Description

The invention relates to a device for holding a bait, in particular a bait for rodents.

Such devices are for pest control, d. H. in particular the control of rodents, such. B. mice and rats, which are in flowed through water channels or lines, d. H. In particular sewage, rainwater or sewage channels and / or cable channels, or corresponding duct or conduit shafts, d. H. generally in water leading facilities, and there considerable damage, eg. B. on wastewater and other infrastructural facilities or facilities can provide provided. Corresponding devices therefore support, typically pest-specific, baits which contain specific poisons or agents which cause the pests to perish in various ways and / or prevent multiplication of the pests.

The toxins or active substances contained in the baits pose a risk potential for humans and nature, so that care must be taken that they do not get into the water flowing through appropriate channels or manholes and contaminate it. However, this can in conventional devices, with large amounts of water and thus high water levels in the channels or manholes, which z. B. after a heavy rainfall the case, occur.

The invention is therefore an object of the invention to provide an improved device for holding a bait, especially a bait for rodents.

• – ein in einen Kanalschacht, insbesondere einen Abwasserkanalschacht oder einen Kabelkanalschacht, einsetzbares Gehäuseteil,
• – wenigstens eine in dem Gehäuseteil angeordnete Köderplattform, welche wenigstens eine Durchgangsöffnung begrenzt, durch welche ein Nagetier zu einem auf der Köderplattform angeordneten Köder und/oder zu einem an wenigstens einer in dem Gehäuseteil angeordneten Köderhalteeinrichtung gehalterten Köder gelangen kann,
• – wenigstens einen Schließkörper, welcher relativ zu der Köderplattform bewegbar gelagert ist, wobei der Schließkörper in einer Offenstellung derart von der Köderplattform weg bewegt ist, dass die wenigstens eine köderplattformseitig begrenzte Durchgangsöffnung freigegeben ist, und in einer Schließstellung derart gegen die Köderplattform bewegt ist, dass die wenigstens eine köderplattformseitig begrenzte Durchgangsöffnung verschlossen ist.

The object is achieved by a device of the type mentioned, which is characterized according to the invention by:

• A housing part which can be inserted into a manhole shaft, in particular a sewer manhole or a cable duct shaft,
• At least one bait platform arranged in the housing part, which delimits at least one passage opening through which a rodent can reach bait held on the bait platform and / or bait held on at least one bait holder arranged in the housing part,
• - At least one closing body which is movably mounted relative to the bait platform, wherein the closing body is moved away in an open position from the bait platform that the at least one bait platform side limited passage opening is released, and is moved in a closed position against the bait platform that the at least one bait platform side limited passage opening is closed.

The principle of the invention relates to a specially designed device for holding a bait for pests, d. H. in particular a bait for rodents, such. B. Mice and rats. The bait contains certain, typically pest-specific, substances, such as. As poisons or active ingredients that bring about a variety of ways, an extinction of pests and / or prevent multiplication of pests. Furthermore, the term pest alone is used. These include, in particular, rodents, such. As mice and rats to understand.

The device according to the invention comprises a housing part. The housing part is in a channel or a manhole, such. B. a sewer manhole and / or a cable duct shaft used. In the channel or manhole is typically water or sewage respectively, the channel or manhole may be at least temporarily flowed through by water or sewage. Furthermore, only the term manhole is used. This includes a part of a water-conducting device, such. B. a sewer for water, d. H. z. B. sewage, rainwater, dirty water, or supply lines, etc. to understand.

In order to realize a stable and secure arrangement of the housing part used in the manhole, this expediently has a fastening device, via which it, in particular detachably, on a wall of the manhole shaft or channel shaft side climbing devices, such. B. duct shaft crampons, can be fastened. The fastening device may, for. B. hook or profile-like fastening means to anchor the housing part and thus the device as a whole in a wall of the manhole, respectively corresponding climbing devices.

The housing part is typically made of a corrosion-resistant material, such. As a stainless steel (sheet) and / or plastic formed. Different sections of the housing part can therefore be formed of different materials. In particular, for the execution of or a portion of the housing part made of plastic that here a transparent plastic material can be used to a, z. B. for the purpose of checking a bait bite, to provide the required insight into the housing part.

The housing part is in particular formed as a hollow cylinder, ie it limits one cylindrical receiving space in which certain components of the device can be received or received.

The housing part can, for. B. on an end face, be closed or closed via a cover element, so that over a removal of the cover element access to the housing part side receiving space can be created. The cover element may have a threaded portion, the housing part may have a threaded portion that is equivalent thereto, so that the cover element can be screwed to the housing part.

Within the housing part, a bait platform is arranged or formed. The bait platform limits at least one passage opening. The passage opening therefore defines a lower area of the housing part lying below this and an upper area of the housing part lying above the latter. The bait is typically located in the upper portion of the housing part. The or a bait can be arranged directly on the bait platform. Alternatively or additionally, the bait or a bait may also be arranged supported on a bait holder for holding a bait. Such a bait holder is accordingly also arranged above the bait platform.

In order to achieve the, as mentioned, typically in the upper region of the housing part arranged bait, a pest must first get into the housing part. For this purpose, the housing part is expediently formed with at least one passage, via which the pest can get into the housing part and / or out of the housing part. A corresponding passage may alternatively or additionally also be formed on a closing body which is yet to be specified. The passage allows access to the lower portion of the housing part. In order to reach the bait, the pest subsequently reached into the housing part must subsequently reach the bait platform and thus the upper area of the housing part through the through-opening delimited by the bait platform. After biting the bait, the pest may pass from the upper area of the housing part into the lower area of the housing part by passing through the passage opening and leave the device via corresponding passages. Of course, it is also conceivable in principle that the or another passage allows access to the upper region of the housing part.

The device according to the invention further comprises a closing body. The closing body is movably mounted relative to the bait platform, which is typically fixedly connected to the housing part. The closing body can be moved relative to the bait platform between an open position and a closed position, as well as possibly reversed. The mounting of the closing body typically includes a captive arrangement or connection of the closing body on or with the housing part.

In the open position, the closing body is moved away from the bait platform such that the at least one bait platform-side through opening is released. Thus, a pest in the open position of the closing body pass through hole to z. B. from the lower portion of the housing part in the upper region of the housing part, or vice versa, to arrive.

In the closed position, the closing body is moved against the bait platform in such a way that the at least one bait platform-side through opening is closed. The closing body typically seals or closes the passage opening hermetically in the closed position. The area of the housing part located above the passage opening is typically hermetically sealed or closed in the closed position of the closing body. Accordingly, a pest in the closed position of the closing body, the passage opening does not pass to z. B. from the lower portion of the housing part in the upper region of the housing part, or vice versa, to arrive.

For the inventive principle, it is essential that the upper portion of the housing part in the closed position of the closing body of the lower portion of the housing part, as mentioned above typically hermetically separated, so that in the closed position of the closing body, for. B. flood or Schwallwasserbedingtes, penetration of water in the upper region of the housing part, in which, as mentioned, typically the bait is arranged, is not possible. Such a principle is given that the above-mentioned problem of contamination of water with substances contained in corresponding baits, d. H. Poisons or active substances encountered. The movement of the closing body from the closed position into the open position can be induced in various ways. This will be discussed later.

The closing body can be reversibly mounted movably between the open position and the closed position. Thus, the closing body located in the closed position of on its own in the open position, and vice versa pass. Alternatively, the closing body can be moved irreversibly between the open position and the closed position be such that it is in the closed position, in particular releasably, halterbar or supported via at least one closing body holding device. About the closing body holding device, the closing body can be held in the closed position accordingly. The closing body located in the closed position can therefore not pass over by itself into the open position here.

The closing body holding device can comprise at least one housing-side and / or closing body-side mechanical and / or magnetic holding means, which is set up for mechanical and / or magnetic holding of the closing body in the closed position. The housing-side or closing body-side mechanical or magnetic holding means can thus cooperate in such a way that the closing body is held securely in the closed position and is not readily detachable from it.

The or a mechanical holding means may, for. B. latching or snap elements, which realize a mechanical support of the closing body in the closed position. When the locking or snap elements, it may be z. B. act by protrusions and corresponding recesses or undercuts. Depending on the structural design of the latching or snap elements, the holder realized via this can be detachable or insoluble.

The or a magnetic holding means may, for. B., in particular permanent magnetic, magnetic elements which realize a magnetic support of the closing body in the closed position due to magnetic interaction. It is conceivable in this context, for. Example, that a housing-side magnetic element is arranged such that it exerts a closing body in the closed position-retaining magnetic force on a closing body side magnetic element when the closing body approaches the closed position and is in the closed position. The magnetic force should not be so high that the closing body located in the open position is moved solely because of this in the closed position. If the closing body is made of a magnetic or magnetizable material, it may be possible to dispense with closing element-side magnetic elements. In principle, the housing part and / or the closing body may comprise corresponding magnetic elements.

The movable relative to the bait platform storage of the closing body can be structurally realized by at least one housing part side guide portion and at least one closing body side guide element, said at least one housing part side guide portion with the at least one closing body side guide element to a movably mounted guide the closing body between the open position and the closed position, and vice versa, interact. In general, a linear guide of the closing body is typically made possible by the interaction of the housing-side guide sections with the closing body-side guide elements. A housing-part-side guide portion may be formed on an outer or inner side of the housing part. A housing-side guide section may, for. B. as a guide rail receptacles, a closing body side guide element can, for. B. be designed as a guide rail or guide bar.

Concerning the structural design of the closing body, it is preferred that this has at least one dome-shaped or conical closing portion, which abuts in the closed position of the closing body sections sealingly formed on the bait platform side edges, which delimit the bait platform side limited passage opening formed investment sections. Due to the sealing contact of the closing body, d. H. corresponding to the closing body-side dome-shaped or conical closing portion trained counter abutment sections, formed on corresponding bait platform side, the passage opening bounding abutment sections is therefore an intrusion of water in the housing receiving the manhole in the housing part, d. H. especially in the upper area of the housing part, not possible.

Suitably, the on the bait platform side, the passage opening limiting edges formed investment sections are therefore at least partially with a sealing element, such as. B. a sealing ring, a sealing lip, etc. provided. Similarly, the closing body-side closing portion, d. H. in particular corresponding formed on this counter abutment sections, at least in sections with a sealing element, such as. B. a sealing ring, a sealing lip, etc., be provided.

In the following, exemplary embodiments of the device will be described with reference to which is explained in more detail how a movement of the closing body from the open position to the closed position, and vice versa, can be induced. The embodiments described below in this connection can be combined with one another as desired.

One embodiment provides that the closing body is designed as a floating body or at least comprises a floating body. A float is a body that floats on a surface of water and does not sink. This can be constructive z. B. be realized by a closing body having at least one cavity. The cavity is filled with air, for example. Alternatively or additionally, the closing body can also be made of a material of low density, which therefore floats on a water surface due to the density difference and does not set. Such a material may, for. As plastic, in particular foamed, plastic. Specifically, it may be so z. B. to foamed thermoplastics, such as. B. foamed polyethylene or foamed polystyrene (styrofoam) act. A movement of the closing body from the open position to the closed position would be induced here automatically by an increase of the water level in the device receiving manhole. Accordingly, a movement of the closing body from the closed position to the open position would be induced by a drop in the water level in the channel shaft receiving the device.

A further embodiment provides that the movement of the closing body from the open position into the closed position is induced by a drive device that can be coupled or coupled to the closing body. The drive device is configured to move the closing body from the open position to the closed position, and / or vice versa. With regard to the design or design of such a drive device, two fundamentally different, but in turn combinable embodiments are conceivable.

A first embodiment of a drive device provides that the drive device is designed as a motor drive device or at least includes such. Consequently, at least one coupled to the closing body motor drive means may be provided, which is adapted to move the closing body from the open position to the closed position, and / or vice versa. In the motor drive device, it may be z. B. act to an electric motor. The coupling between the motor drive device and the closing body can, for. B. be realized by suitable traction means, such as in the form of ribbons or chains. Of course, the closing body may also be formed in this embodiment as a floating body or at least comprise a float.

A second embodiment of a drive device provides that the drive device is designed as a magnetic drive device or at least includes such. Consequently, at least one coupled to the closing body or coupled magnetic drive means may be provided which is adapted to move the closing body from the open position to the closed position, and / or vice versa. Also in this embodiment, the closing body may be formed as a floating body or comprise at least one float.

The magnetic drive device typically comprises at least one magnetizable and / or magnetic magnetic element on the part of the housing and on the part of the closing body. So both electromagnetic and permanent magnetic magnetic elements come into consideration. In a magnetizable magnetic element, it can be z. B. to an electromagnet, which exerts a magnetic attraction when energized act. In a magnetic magnetic element, it may, for. B. to a permanent magnet, which has a static magnetic field act. In any case, the housing-side and the closing body side magnetic elements interact with each other such that a high magnetic attraction force is exercised, due to which the closing body can be moved from the closed position to the open position.

In this context, different configurations are conceivable. So it is z. B. possible that the housing part side, at least one electromagnetic magnetic element is arranged, which can be energized if necessary, and interacts with energization with at least one closing body side permanent magnetic magnetic element, that the closing body can be moved due to magnetic attraction of the open position in the closed position. The or a closing body side (s) magnetic element can be arranged on an exposed surface of the closing body or integrated into the closing body. Of course, the closing body as such also from a magnetic or magnetizable material, such as. B. ferritic steel, or filled with magnetic or magnetizable particles plastic.

In principle, however, it is also possible to provide at least one electromagnetic magnetic element on the closing body side and at least one permanent magnetic magnetic element on the housing side.

Equally, both the housing part side and the closing body side corresponding electromagnetic magnetic elements may be provided.

It is also conceivable to provide both the housing part side and the closing body side at least one permanent magnetic magnetic element, so that with sufficient approximation of the The closing body side magnetic element is moved to the housing-part-side magnetic element of the closing body due to magnetic attraction from the open position to the closed position. The adequate approximation can z. B. be achieved when designed as a floating body or at least one such comprehensive closing body, z. B. due to flooding, starting from the open position to a certain extent in the direction of the bait platform, ie in a position lying between the open position and the closed position, is moved. Of course, in this embodiment care must be taken that the magnetic attraction or interaction existing between the respective permanent magnet magnetic elements is not so high that the closing body located in the open position is moved into the closed position solely because of this.

Based on the described embodiments of a motor and / or an electromagnetic drive device, it is conceivable that an associated control device is provided, via which the control of the operation of the drive device (s) takes place. The control device is thus set up to generate control information controlling the operation of the motor and / or electromagnetic drive device (s).

The control device may be further configured to generate the control information in dependence on a water level information supplied by a water level detection device for detecting the water level in the manhole receiving the device, or the water level in the manhole receiving the device. Consequently, a control of the operation of the motor and / or electromagnetic drive device can take place as a function of the water level detected by a corresponding water level detection device and depicted in a corresponding water level information in the manhole shaft receiving the device. On the part of the control device certain critical water levels can be taken into account, when they reach the penetration of water into the housing part and in particular in the upper region of the housing part, d. H. In general, the area of the housing part, in which the bait is arranged, is possible in principle, so that the control device provides timely appropriate control information to the motor and / or electromagnetic drive means to prevent ingress of water into the housing part or the area of the housing part, in which The bait is arranged to prevent.

The water level detection device may form part of the device. However, this is not absolutely necessary; rather, the control device can also be set up with at least one external, d. H. spatially separated from the device to communicate water level detection device. This may be, in particular, a water level detection device located downstream in relation to the position of the device in the manhole shaft, so that an imminent high water level can be detected in good time. Of course, the device or the control device for this purpose suitable receiving devices, which one, in particular radio-based, d. H. z. B. via Bluetooth, WLAN, etc., enable data or information exchange with a water level detection device.

The device may further comprise a closed position detection device for detecting the closed position of the closing body. The closing position detection device, which is typically arranged in the housing part, is designed to generate at least one acoustic and / or optical closing position information upon detection of the closed position of the closing body and to output it via at least one output device. In this way, it is possible to detect the reaching of the closed position and to display via acoustic and / or optical signals in a simple manner, which may be expedient in the case of service or repair work. The service or Repair personnel can be indicated that a high level of water has been or has been reached in the channel, as a result of which the closing body has been moved to the closed position or is still held in the closed position. The closed position detection device accordingly comprises a suitable sensor for detecting the closed position of the closing body. The sensor system may, for example, be designed optically, ie, for example, via the implementation of light barriers.

As mentioned, the bait can be arranged or arranged on a bait holder for holding a bait. In the event that the device is equipped with such a bait-holding device, it may be expedient if the device further comprises a bite-detecting device for detecting a bait bite. The bite detection device typically arranged in the housing part is configured to generate at least one acoustic and / or optical bite information upon detection of a bitten bait or a bait bite and to output it via at least one output device. In this way, it is possible to detect bait biting by a pest and to display it easily via acoustic and / or optical signals, which in turn may be expedient in the case of service or repair work. The service or repair personnel can be indicated that a bait bit has been bitten and thus a check is made as to whether a new bait is to be inserted into the housing part or into the device. The bite-detecting device accordingly comprises a suitable sensor system for detecting a bait bite. For example, the sensors can detect the weight of the bait arranged on the bait-holding device, whereby bite-related weight changes, typically weight reductions, of the bait allow conclusions to be drawn about a bait bite. Likewise, the sensors may sense biting forces acting on the bait and / or the bait holder, typically tensile forces, which also allow conclusions to be drawn about bait biting.

The snack detection device can, depending on the bite information, z. B. based on the detection of the weight of the bait, different acoustic and / or optical signals. The weight of a new, not bitten bait can z. B. be signaled with optical signals of green color and / or with permanently constant output optical signals, the weight of a partially delivered bait z. B. signaled with optical signals yellow color and / or output at a first flashing frequency optical signals, the bait is completely eaten can this z. B. be signaled by optical signals of red color and / or output at a higher compared to the first flashing frequency second flashing frequency optical signals.

The same applies, of course, for the output of acoustic signals, in particular the frequency and / or the rhythm of a tone or a tone sequence depending on the Anbissinformation, z. B. based on the detection of the weight of the bait, are variable. The same applies, of course, for the case that the snack detection device does not draw on the weight but on other measured variables, conclusions on a bait bite.

An acoustic output means can, for. B. be designed as speakers or at least include such. An optical output means may, for. B. as, in particular multi-colored, light-emitting diode or screen or be at least one (n) include such (n).

The or an output means may be arranged on or in the housing part, wherein it is arranged on an exposed outer surface of the housing part or within a limited by the housing part receiving space. In particular, for optical output means that, if this is within the housing part, d. H. are arranged within a bounded by the housing part receiving space of the housing part, the housing part should be at least partially partially transparent, to make the optical signals from outside the housing part recognizable.

The or an output means may also be integrated in an external mobile terminal. If the or an output device is integrated in an external mobile terminal, the closed position detection device and / or the bite detection device may be configured to communicate with the external mobile terminal and the closed position information and / or the bite information to the external mobile terminal for output to the local Transfer output medium. Service or operating personnel can be informed in such a way without entering the sewers on reaching the closed position of the closing body and / or a bait bite. The communication described is particularly radio-based, d. H. z. B. via Bluetooth, WLAN, etc. realized, which is why the closed position detection device and / or the Anbisserfassungseinrichtung comprise corresponding radio-based transmitting devices. In an external mobile device, it may, for. B. a cell phone, smartphone, tablet, a notebook, etc. act.

In view of the large number of optionally be arranged in the housing part electrical and / or electronic components, d. H. In particular, corresponding control or detection devices, it may be appropriate that in the or limited by the housing part receiving space at least one receiving chamber is formed or arranged, in which electrical and / or electronic components of the device, in particular control devices and detection devices, can be arranged or arranged , The receiving chamber thus offers a protection of these components from the outside, d. H. especially climatic and mechanical, influences. The receiving chamber may be formed integrally with the housing part or as a separate component, which is to be used separately in the housing part side receiving space. The receiving chamber can be closed or closed via a cover element, which may also be the housing-side cover element mentioned above, so that access to the receiving chamber can be provided by removing the cover element.

The or a receiving chamber, in which corresponding electrical and / or electronic components of the device, in particular control devices and detection devices, can be arranged or arranged, one, in particular cylinder-like or cylindrical, a receiving chamber volume for receiving electrical and / or electronic components of the device limiting receiving chamber main body which projects at least partially into the housing part side receiving space.

The receiving chamber is expedient releasably fastened or fixed to the housing part. The receiving chamber can therefore be arranged on or in the housing part and removed from it. Of course, the receiving chamber base body protrudes only in the attached to the housing part state of the receiving chamber in the housing part side receiving space. The releasable attachment of the receiving chamber to the housing part can be formed or formed by, in particular form-fitting, cooperation of at least one housing part-side fixing portion with at least one receiving chamber body-side fixing portion. The receiving chamber and the housing part are thus each equipped with at least one attachment portion, on the interaction of which a stable or captive, yet releasable attachment of the receiving chamber can be realized on the housing part. Under a, in particular form-fitting, cooperation of respective fastening portions is to be understood in particular an at least partially interlocking or overlapping corresponding fastening sections.

The receiving chamber can be arranged rotatably mounted or arranged on the housing part between a mounting position and a release position. In the attachment position, the at least one housing-part-side attachment portion and the at least one receiving chamber base body-side attachment portion, in particular a form-fitting, cooperate, so that the receiving chamber is releasably secured to the housing part. In the release position, the at least one housing-side fastening section and the at least one receiving chamber base body-side fastening section do not act together, so that the receiving chamber can be detached from the housing part. The attachment of the receiving chamber to the housing part can thus be made and canceled by rotational movements of the receiving chamber about an axis of rotation, which typically coincides with the central axis of the receiving chamber, relative to the housing part. The receiving chamber can thus be transferred by rotational movements relative to the housing part of the mounting position in the release position, and vice versa.

The or at least one housing-side attachment portion may, for. B. as a radially projecting from a cylinder-like portion of the housing part annular disk element or ring segment disk element with at least one of this axially projecting shoulder-like fastening projection. The or at least one receiving chamber body-side fixing portion may, as a radially projecting from a cylinder-like projection of the receiving chamber body annular disc member or ring segment disc member with a corresponding to the housing-side attachment portion formed fastening projection, d. H. be formed in particular opposite trained or aligned, axially projecting shoulder-like fastening projection.

To realize corresponding rotational movements of the receiving chamber, the receiving chamber in the region of an upper exposed cover portion at least one tool engagement area for positive engagement of a tool, which tool can be rotational movements transmitted to the receiving chamber to transfer the receiving chamber from the mounting position to the release position, and vice versa , on. By arranging or forming at least one corresponding tool engagement region in the region of an upper exposed cover section of the receiving chamber, the tool engagement region is always accessible (from above). The geometric shape of the tool engagement area is such that a, z. B. T-shaped, form-fitting tool can engage this, so that rotational movements can be transferred to the receiving chamber.

The tool engagement region is also good, especially in the state of the device properly inserted into a manhole, d. H. especially from above, accessible. By suitable shaping and dimensioning of a corresponding tool, it is not absolutely necessary for a user to descend into the manhole shaft in order to transfer the receiving chamber by corresponding rotational movements from the fastening position into the release position, or vice versa. The receiving chamber can thus be solved from outside the manhole of the housing part and optionally removed from the manhole. This can, for example, for control purposes, for. For example, determining whether bait baiting has taken place can be practicable so that controls can be considerably simplified and carried out considerably more swiftly.

In particular, if the bait or a bait held on the receiving chamber or trained bait holding device is supported for holding a bait, the receiving chamber together with bait holder and bait held it without entry into the manhole of the manhole taken, any bait bite detected, optionally an exchange or replacement the bait or bait made, and the receiving chamber together with bait holder and bait held it be introduced back into the manhole.

From the above paragraph it follows that the or generally a bait holding device for holding a bait is advantageously arranged or formed on the receiving chamber. In this case, the bait holding device is arranged or formed, in particular, on a section of the receiving chamber projecting into the housing-part-side receiving space.

At least one, in particular optical, monitoring device for monitoring at least part of the receiving space bounded by the housing part can be arranged or formed on the or a corresponding receiving chamber. The monitoring device is generally arranged or formed on or in the receiving chamber in such a way that the widest possible monitoring of the receiving space bounded by the housing part can be realized. The monitoring device typically comprises a suitable, in particular optical, sensor system for monitoring at least part of the receiving space bounded by the housing part. The monitoring device can therefore be designed as an infrared sensor or camera or at least comprise an infrared sensor or camera. Of course, the monitoring device can in principle be designed differently. It would be conceivable z. B. the implementation of a monitoring device in the form of a video camera or the like.

Regardless of the specific embodiment of the or generally a corresponding monitoring device, it is therefore possible to detect and evaluate all operations in or an area of the receiving space bounded by the housing part. In particular, rodent-related processes can be quantitatively and / or qualitatively recorded and evaluated or assessed. Quantitative and / or qualitatively monitored processes of particular interest include, for example, infestations of pests in the receiving space, leaks of pests from the receiving space, the behavior, d. H. in particular the biting and / or movement behavior, respective pests in the receiving space accessed in the receiving space etc. In general, the frequency of the receiving space per specific unit of time can be quantitatively and / or qualitatively recorded and evaluated or assessed. Since monitoring information or data acquired by the monitoring device can of course be transmitted via a suitable, in particular radio-based, communication connection to a user-side, in particular mobile, external terminal, monitoring of all processes in the area bounded by the housing part can be monitored via a corresponding monitoring device Realize receiving space of the housing part without the need for entry into the manhole or in the sewer. The communication is in particular radio-based, d. H. z. B. via Bluetooth, WLAN, etc. realized, which is why the monitoring device comprises a corresponding radio-based transmitting device. In a, in particular mobile, external terminal can in turn z. B. to a mobile phone, smartphone, tablet, notebook, etc. act.

The or in general a monitoring device can be supplied with electrical energy via a receiving or arranged in the receiving chamber, in particular rechargeable, electrical energy storage. As a corresponding electrical energy storage is, for example, an electrochemical or galvanic energy storage in the form of a, in particular rechargeable, battery in question. Also conceivable is an inductive, d. H. a by means of electromagnetic induction, rechargeable energy storage. In principle, the electrical power supply of a corresponding monitoring device can also be realized via a wired connection of this to a power supply network.

Incidentally, the same applies to the electrical power supply of other arranged and trained in the receiving chamber electrical and / or electronic components of the device.

The device may comprise at least one surge protection element for protecting the penetration of water into or through the housing part bounded receiving space, in particular in a above the bait platform side limited through hole upper portion of the receiving space, at a surge or suddenly rising water level in the manhole in which Insert or insert the housing part include. The surge protection element is typically located below the bait platform. The surge protection element can be arranged at least in sections inside or outside the housing part.

The anti-surge element may have a base body which limits at least one water surge receiving volume for receiving a certain amount of water flowing in the or a manhole. The main body of the splash water protection element may, for. B. be cylindrical or cylindrical. Also conceivable are polygonal (polygonal), in particular square, basic shapes. The or generally at least one closing body is included at least partially movably mounted within the main body of the surge protection element, such that it is moved from the open position to the closed position at a concomitant with the entry of water into the at least one water surge receiving volume increase in the water level in the water surge receiving volume. In the closed position of the closing body is typically with a corresponding, in particular dome-shaped or conical closing portion, partially sealingly on at the bait platform side edges, which delimit the bait platform side limited passage opening, trained abutment sections. In the case of the closing body, it is expedient, but in view of the above statements, in connection with corresponding drive devices which can be coupled or coupled to a closing body, not necessarily to be a floating body.

In the region of its side facing away from the bait platform, the main body of the surge protection element may comprise a bottom surface having at least one surge water inlet opening. The closing body may be arranged in the open position at least partially in the surge water inlet opening. When increasing the water level in the manhole, the, in particular designed as a floating body, closing body lifts from the surge water inlet, so that water can enter the Wasserschwallaufnahmevolumen until the closing body due to the increase of the water level in the water surge volume finally, as described, from the Open position is moved to the closed position. Of course, it is also conceivable that the main body of the surge protection element in the region of its side remote from the bait platform is completely open. In particular, in this case, the closing body can be supported via a suitable holder.

The main body of the anti-surge element may be a number of, for. B. web-like, feet have, which are the storage of the body, possibly also the arranged on this housing part together with the arranged or fixed therein components of the device used.

In principle, the housing part can be provided with stiffening structures for increasing the mechanical stability of the housing part. Corresponding stiffening structures can, for. B. ring or rib-like, be formed. Corresponding stiffening structures may be present as separate components, which are to be attached to or correspondingly connected to the housing part, or be formed integrally with the housing part.

In order to make it easier for a rodent to access the bait platform via the closing body, the closing body can be provided at least in sections with surface structuring and / or surface coating and / or surface coating providing at least one retention and / or adhesion for a rodent entering the closing body. A corresponding surface structuring or surface coating or inhibits slipping of the rodent of the closing body, thus serves in the sense of a "boarding aid" and facilitates a rodent access to the bait platform, generally the access to the interior of the housing part. Of course, a corresponding surface structuring and / or surface coating and / or surface support a rodent vice versa also in the sense of "exit aid" and facilitates a rodent sonach also leaving the bait platform, generally the output from the interior of the housing part.

The or at least a corresponding hold and / or adhesion for a rodent entering the closing body, typically three-dimensional, surface structuring can be formed, for example, by corrugated and / or rib and / or bead structures in the surface of the closing body. A corresponding surface structuring can form a rung or step-like structuring of a surface section of the closing body. A certain roughening of the surface can also serve as appropriate surface structuring. The surface coating or at least one stop and / or adhesion for a rodent that enters the closing body can be formed, for example, by a rubber-like coating. In general, any adhesion of a rodent to the closing body can be improved by coatings, e.g. B. based on natural or synthetic rubbers, silicones, etc., at least partially applied to the surface of the closing body. The or at least one surface support may be formed, for example, by a rubber-like surface support fixed at least in sections on the surface of the closing body. A corresponding surface support is to be fastened in a suitable manner to the closing body, for which purpose all positive and / or non-positive and / or cohesive fastening types come into question; merely by way of example reference is made to clipping, gluing, screwing, embossing, etc.

For the exemplary case of a dome-shaped or spherical segment-shaped closing body, a corresponding surface structuring and / or surface coating and / or surface coating can be applied at least in sections on one side be arranged or formed circular disc-shaped portion of the spherical segment-shaped closing body.

For the realization of the described above, movable relative to the bait platform storage of the closing body, it is conceivable that the closing body by means of at least one movable, in particular pivotable, on or in the housing part, in particular on the bait platform, mounted clamp or clasp-like holding element movable relative is stored to the bait platform. In this case, a corresponding holding element to be referred to as a retaining clip or retaining clip is typically fastened to the closing body on the one hand, in particular at one end, on the housing part or the bait platform and on the other hand, in particular at the other end. About the connection of the closing body to the holding element, the connection of the holding element to the housing part or the bait platform and the geometric dimensions, d. H. in particular the shape of the retaining element defines a certain trajectory, the closing body in a movement from the open position to the closed position, and vice versa, passes through.

The clasp-like or clip-like holding element may comprise at least two holding element sections running parallel or at an angle to one another, wherein at least one holding element section engages through the through opening delimited by the bait platform at least in the open position of the closing body. Corresponding holding element sections and thus the entire holding element can be bent in an L-shaped manner, for example. H. indicate a (substantially) L-shaped geometric shape.

Another possible realization of the movable mounting of a closing body can take place by means of a flap device. A corresponding flap device may comprise at least one movable, in particular pivotable, mounted flap element relative to the bait platform, which in an open position is moved away from the bait platform such that the at least one bait platform-side through opening is released, and in a closed position against the bait platform is moved, that the at least one bait platform side limited passage opening is closed. The closing body can be an integral part of the flap device here in the form of a corresponding flap element. Of course, it is alternatively also possible to attach a separate closing body to a corresponding flap element. Of course, also in this embodiment, a closing body may be formed as a floating body or at least comprise a float.

A corresponding flap device may also comprise a plurality of flap elements which are moved in a respective open position away from the bait platform such that the at least one bait platform side limited passage opening is released, and are moved in a respective closed position against the bait platform that the limited at least one bait platform side Passage opening is closed by the flap elements together.

A particularly expedient component of the device may be a fastening device, by means of which the housing part, in particular detachably, can be fastened to a wall of a sewage system, in particular of a manhole. A corresponding fastening device may comprise at least one, in particular annular, first fastening element and at least one second fastening element for fastening the first fastening element to the wall of a sewer system, which surrounds the outer peripheral side of the housing part. An appropriate fastening device thus makes it possible to provide stable attachment of the housing part to a wall of a sewage system or a manhole, in particular with regard to flood or water-induced forces acting on the housing part. The attachment of the second fastening element to the wall of a sewer or a manhole may, for example, be realized via fastening bolts or bolts extending from the second fastening element or from the second fastening element, optionally threaded, horizontal or vertical bores. z. B. by walls or screws, are stably anchored in the wall of a sewer or a manhole.

All components of the fastening device are expediently made of one or more mechanically stable and corrosion-resistant materials, eg. As stainless steels, or material structures formed or include such materials or material structures. As will be seen below, a corresponding fastening device can also ensure a buoyancy protection of the housing part.

In general, the fastening device can be designed in one or more parts. The first and the second, ie in general at least one further fastening element, can thus be integrally formed with each other or formed in several pieces and secured to each other accordingly. For attachment of respective fasteners to each other come basically all ( damage-free or non-destructive) releasable or non-releasable positive and / or non-positive and / or cohesive fastening types into consideration.

In order to realize a buoyancy protection, the second fastening element may comprise at least one fastening element section which engages over the housing part at least in sections to form a buoyancy protection at least in sections. The housing part is therefore protected against flooding or flood-related buoyancy forces and fixed in its, in particular vertical, positioning fixed to or in the sewer system. In other words, the housing part engaging over the top side of the fastener section can absorb flooding or surge water-induced buoyancy forces.

Of course, it is possible to provide several corresponding fastener sections. Thus, for example, at least two, in particular angled, preferably V-shaped, mutually extending fastener element sections may be present. A fastener portion may basically have any geometric shape. For example, reference is made to leg or strut-like fastening element sections.

Corresponding fastening element sections can be detachably, fastened or fastened to the exposed upper side of the housing part, in particular in a form-fitting manner (damage-free or non-destructive). The attachment thus takes place in particular by a positive connection, d. H. on the positive interaction of positive locking elements on the part of the fastener sections with this form-fitting elements on the part of the housing part. Formed on respective fastener sections form-fitting elements can, for. B. formed as a recess or aperture, formed on the housing part interlocking elements may be formed for example by, in particular vertical, projections which engage in the attached state in or through corresponding recesses or openings. Of course, a mixed or reverse configuration of corresponding recesses or openings and projections is possible.

The or at least one corresponding fastener portion may be releasably or non-detachably fastened or fastened as a separate component to a profile-like base body of the second fastener form and / or force and / or material fit (damage or destruction). For example only, in this context, reference is made to a clamping, screwing or welding fastening. It is also conceivable that the or at least one corresponding fastener section is formed integrally with the or a profile-like base body of the second fastener.

The or at least one fastening element section may be formed at least in sections with at least one, in particular cross-section reducing, stiffening structure for increasing the mechanical stability of the fastening element section. In this way, the material thickness and thus the weight of the fastening device can be reduced without sacrificing the mechanical stability of the fastening device.

Corresponding stiffening structures can be formed, for example, by ribs, beads, etc.

As an alternative to the attachment of the housing part by means of a corresponding fastening device, it is conceivable to clamp the housing part by means of a tensioning device against the walls of a sewer or a manhole and to fasten it in such a way. The tensioning device can comprise a plurality of clamping elements, which are arranged distributed in a typically equidistant manner and protrude radially from the housing part, which clamp the latter against corresponding walls.

In the housing part can several, d. H. at least two, bait platforms be arranged, wherein at least one closing body is movably mounted relative to at least one bait platform, wherein the closing body is moved in an open position of the respective at least one bait platform away, that the respective at least one bait platform side limited passage opening is released, and in a closed position is moved against the respective at least one bait platform, that the respective at least one bait platform side limited passage opening is closed. The principle described at the outset of the hermetically sealing closure of a bait platform side limited passage opening via a closing body moved into a corresponding closed position thus applies equally here. The closing body typically seals or closes off a respective passage opening in the closed position hermetically. Accordingly, the area of the housing part located above the passage opening is typically hermetically sealed or closed in the closed position of the closing body.

Respective bait platforms are typically arranged above or below each other. Depending on the geometry of the respective bait platforms, several bait platforms may be arranged in parallel at least in sections. Between two ( immediately adjacent bait platforms, a gap defining an intermediate plane is typically formed. Respective gaps do not have to be the same in terms of their shape, their volume, etc., but may be different. This applies to the exemplary case of more than two bait platforms and thus at least two corresponding spaces. Respective intermediate spaces communicate with each other via respective passage openings delimited by the bait platform; There is therefore a passageway from a "bottom" bait platform to a "top" bait platform.

Corresponding gaps can cause a flow-related "calming", generally an influence on the flow, of water rising in the housing part. The inflowing into the housing part and rising in this water must therefore "walk" the way over several intermediate levels upwards, which typically leads to a "calming" of the flow of water. Respective lure platforms can also at least in sections with a flow, in particular the type of flow or the flow velocity, from along this flowing or rising in the housing part ascending water surface structuring, z. B. in the form of flow-influencing ribs and / or beads, be provided.

Due to the presence of several spaces, it is also possible to equip the housing part with a larger number of baits in comparison, since bait can be arranged in principle in several levels. The housing part can be haunted so far compared in comparison of more rodents.

In addition, the mechanical stability, in particular the rigidity, of the housing part can be increased by the presence of several intermediate spaces. The housing part can be additionally "stiffened" by the bait platforms arranged in it.

Respective passage openings delimited by respective bait platforms may be offset relative to each other. In general, at least one bait platform-side through opening of a first bait platform can be offset from the at least one bait platform-side defined through opening of a bait platform adjacently arranged to the first bait platform. For example, a through opening of a first bait platform may be formed in an edge region of the first bait platform and a through opening of another bait platform adjacent to the first bait platform may be formed in an oppositely disposed edge region of the further bait platform. Due to the staggered arrangement of respective passage openings is also a "reassurance", generally influencing the flow of, in the housing part, for. B. meandering, ascending water possible. The staggered arrangement of respective through openings also facilitates the movement of a pest between respective spaces or intermediate levels.

At least one bait platform may be formed, at least in sections, with a lure platform section extending inclined or curved or curved relative to at least one further bait platform, in particular adjacent thereto. By appropriate inclined or curved or curved courses corresponding bait platforms can also be realized an effect on the flow of ascending water in the housing part. Inclined or curved or curved courses of corresponding bait platforms can also facilitate the entry or exit of pests between respective spaces or intermediate levels in the sense of ascending or descending ramps.

As a further measure for influencing the flow of ascending water in the housing part, at least one bait platform can be formed at least in sections with these duretting borehole-like openings or perforations. Respective openings of a bait platform, generally similar to a perforated structure, can "dampen" the flow of rising water and thus also "calm" it. The openings are present in addition to respective through holes and differ in particular in their size, d. H. in particular their diameter, of respective passage openings; the openings are small compared to respective through holes. For example, round openings may have a diameter between 50 μm and 3 mm. Of course, different openings with different geometries may be present.

In general, ie basically independent of the provision of several bait platforms, it should be noted that, when water flows into or into the housing part, a counterpressure forms in the housing part due to the given volume (inner volume) and the tightness of the housing part. which is opposite to the inflowing or ascending water respectively counteracts the inflow or rising of water. This results from the fact that the air in the housing part is compressed by the inflow and rising of water. The rising of water in the housing part is therefore due to the forming Counterpressure increasingly difficult. This principle is of course also given in the presence of multiple bait platforms, so that the ascending water in the housing part on reaching a certain bait platform such a high back pressure is opposite, that it can no longer rise at the given flow.

Further generally, d. H. In principle, regardless of the provision of several bait platforms, it is conceivable that the or at least one bait platform is at least partially helical or helical formed at least partially extending through the housing part. About a corresponding spiral or - similar to a spiral staircase - helical trained bait platform can penetrate into the housing part pest in a simple manner within the housing part, z. B. to get to a bait. Spiral bait platforms may also have an influence on the flow of water rising in the housing part. In the case of multiple bait platforms, it is possible that one or more bait platform (s) are formed at least in sections with a corresponding spiral or helical course.

The invention further relates to a manhole, generally a shaft-like structure or a shaft-like structure section comprising at least one device as described. In a corresponding manhole may be in particular a sewer manhole or a cable duct shaft. With regard to the manhole, all designs in connection with the device apply analogously.

Further advantages, features and details of the invention will become apparent from the embodiment described below and with reference to the drawings. Showing:

1 - 4 each a schematic diagram of a device for holding a bait according to an embodiment of the invention; and

5 - 9 each a schematic diagram of a device for holding a bait according to another embodiment of the invention;

10 - 13 each a schematic diagram of a device for holding a bait according to another embodiment of the invention; and

14 - 26 each a schematic diagram of a device for holding a bait according to another embodiment of the invention.

1 shows a schematic diagram of a device 1 for holding a bait 2 according to an embodiment of the invention. The bait 2 Contains substances, ie in particular poisons and active substances, which cause the death of pests and / or prevent the multiplication of pests.

The device 1 includes a housing part 3 , The housing part 3 is in a sewer 4 , ie, for example, a sewer or sewer manhole used. The attachment of the housing part 3 via a in the 1 - 4 Not shown in detail housing-side fastening device, via which the housing part 3 , in particular detachably, on a wall of the sewer system 4 is attached. The fastening device 35 may comprise hook or profile-like fastening means, so that the housing part 3 in the wall of the sewer 4 or corresponding channeling-side climbing devices (not shown), such. As crampons, can be attached.

The housing part 3 is made of a corrosion-resistant material, such. B. a steel sheet and (essentially) formed as a hollow cylindrical body, ie the housing part 3 defines a (substantially) cylindrical receiving space 5 ,

In the area of an upper end side of the housing part 3 is a lid element 6 intended. The housing part 3 is therefore frontally on a cover element 6 closable. About removing the cover element 6 can provide access to the recording room 5 be created. The cover element 6 has a threaded portion (not shown), the housing part 3 has a threaded portion (not shown) opposite thereto, so that the lid member 6 with the housing part 3 can be screwed. Between the lid element 6 and the housing part 3 is also a sealing element 7 arranged, which is a seal of the housing part 3 allows in the upper end face.

In the recording room 5 is a, typically annular, bait platform 8th educated. The bait platform 8th defines a, typically circular, passage opening 9 , The passage opening 9 defines an upper area above it 5a of the recording room 5 and a lower area below it 5b of the recording room 5 , The constructive connection of the bait platform 8th to the housing part 3 takes place with respect to the outer wall 10 of the housing part 3 radially inwardly offset inner walls 11 ,

The bait 2 is in the upper area of the recording room 5 arranged. This is a bait holder 12 for holding the bait 2 provided at the free end of the bait 2 is arranged stably. In principle, the or another bait could 2 but also directly on the bait platform 9 be arranged.

Between the outer wall 10 of the housing part 3 and the radially inwardly offset inner walls 11 are housing-side guide sections 13 formed in the form of elongated guide shots. The housing-side guide sections 12 act with this corresponding guide elements 14 in the form of elongated guide webs of a closing body 15 together. Due to the interaction of the housing-side guide sections 13 with the closing body side guide elements 14 is a linear guide and thus a movable mounting of the closing body 15 realized, which makes it possible, the closing body 15 relative to the bait platform 8th to move. The storage of the closing body 15 includes a captive arrangement or connection of the closing body 15 on or with the housing part 3 ,

As part of the movable storage of the closing body 15 is an open position and a closed position provided. The closing body 15 is thus mounted or guided in particular between a movable in the open position and a closed position. The closing body 15 can therefore between an open position and a closed position, and possibly vice versa, relative to the bait platform 9 to be moved.

In the in 1 shown open position is the closing body 15 like that from the bait platform 8th away moves that the bait platform side limited passage opening 9 is released. Thus, a pest in the open position, the passage opening 9 happen to z. B. from the lower area 5b of the recording room 5 in the upper area 5a of the recording room 5 , or vice versa, to arrive. In the in 2 shown closed position is the closing body 15 so against the bait platform 8th moves that the bait platform side limited passage opening 9 is closed. Accordingly, a pest in the closed position, the passage opening 8th do not happen to B. from the lower area 5b of the recording room 5 in the upper area 5a of the recording room 5 , or vice versa, to arrive.

To the one in the upper area 5a of the recording room 5 arranged bait 2 To reach, a pest must first in the housing part 3 reach. For this purpose, in the closing body side guide elements 14 crossings 21 educated. The passages 21 allow access to the lower area 5b of the recording room 5 , To the bait 2 to reach, the pest must further through the bait platform side limited passage opening 9 on the bait platform 8th and thus in the upper area 5a of the recording room 5 reach. After bite of the bait 2 can the pest by passing through the passage opening 9 from the upper area 5a of the recording room 5 in the lower area 5b of the recording room 5 arrive and the device 1 via corresponding passages 21 leave.

The in the closed position of the closing body 15 realized closure of the bait platform side limited through hole 9 prevents in particular a, z. B. in high or splash water possible, unwanted ingress of water in the upper area 5a of the recording room 5 in which the bait 2 is arranged. Consequently, in the closed position of the closing body 15 the risk of contamination of the water in the manhole with those in the bait 2 eliminated substances removed.

Obviously, the closing body 15 a dome-shaped closing portion 16 on, which in the closed position partially sealing on at the bait platform side edges, which the bait platform side limited passage opening 9 limit, trained investment sections 17 is applied. By the sealing system corresponding to the dome-shaped closing portion 16 trained counterpart sections 18 , at corresponding bait platform side abutment sections 17 is an ingress of water in the upper area 5a of the housing part side receiving space 5 prevented. At the bait platform side abutment sections 17 are also sealing elements for the purpose of sealing 19 formed in the form of sealing lips. With the same purpose are also on the closing body side counter abutment sections 18 sealing elements 20 formed in the form of sealing rings. Visible are further, unspecified sealing elements in the form of sealing lips in the region of the opening of the housing part side guide portion 13 as well as on lateral areas of the closing body 15 intended.

The movement of the closing body 15 from the open position to the closed position takes place in the in the 1 . 2 shown embodiment by an increase in the water level in the manhole 4 , This is related to that of the closing body 15 is designed as a floating body. The closing body 15 thus has z. B. an approximately filled with air cavity (not shown). Alternatively or additionally, the closing body 15 be made of a, in particular foamed, plastic material of low density, which floats due to the difference in density on a water surface and does not set. A movement of the closing body 15 from the open position to the closed position is therefore automatically induced by an increase in the water level in the manhole. Accordingly, a movement of the closing body 15 from the closed position into the open position induced by a drop in the water level in the manhole.

The closing body 15 can be mounted reversibly or irreversibly movable The described movement of the closing body 15 from the open position to the closed position can therefore be reversible or irreversible. A reversibly movable mounting of the closing body 15 means that the closing body 15 can move from the open position to the closed position by itself. An irreversibly movable bearing means that the closing body 15 in the closed position, in particular releasably, via a closing body holding device (not shown) can be held or held, and thus can not pass from the closed position by itself in the open position. A corresponding closing body holding device typically comprises at least one housing-side and / or closing body-side mechanical and / or magnetic holding means, which leads to a mechanical and / or magnetic retention of the closing body 15 is set in the closed position. The housing-side or closing body-side mechanical or magnetic holding means can thus cooperate such that the closing body 15 securely held in the closed position and not readily solvable from this.

3 shows a device 1 according to a further embodiment of the invention. Unlike in the 1 . 2 embodiment shown, the device comprises 1 here one with the closing body 15 coupled motor drive device 22 in the form of an electric motor, which is (r) adapted to the closing body 15 from the open position to the closed position, and / or vice versa to move. A movement of the closing body 15 from the open position to the closed position can therefore specifically here by a with the closing body 15 coupled motor drive means are induced. The coupling between the motor drive device 22 and the closing body 15 is about a traction device 23 realized in the form of a chain. Of course, the closing body 15 be formed in this embodiment as a floating body.

The control of the operation of the motor drive device 22 via a control device associated therewith 24 used to generate the operation of the motor drive device 22 controlling information is set up.

The control device 24 is further adapted to the control information in response to a of a water level detection device 25 for detecting the water level in which the device 1 supplied to the receiving manhole, or to generate a water level in the manhole descriptive water level information. Thus, a control of the operation of the motor drive device 22 depending on a corresponding water level detection device 25 recorded and displayed in a corresponding water level information water level in which the device 1 take place receiving manhole.

In the in 3 the embodiment shown is the water level detection device 25 externally, ie spatially separated from the device 1 arranged. As a result, the controller is 24 also equipped with the (external) water level detection device 25 , z. B. radio-based, to communicate. For this purpose, the control device comprises 24 a suitable receiving device and the water level detection device 25 a suitable transmitting device. The or a corresponding water level detection device 25 However, in principle, in the device 1 be integrated.

4 shows a device 1 according to a further embodiment of the invention. Unlike the in 3 shown embodiment here is no motor drive device 22 but a magnetic drive device 32 intended. The magnetic drive device 32 includes one in the upper area 5a of the recording room 5 arranged electromagnetic magnetic element 33 and a closing body side arranged permanent magnetic magnetic element 34 , The housing-side permanent magnet magnetic element 33 exerts upon energization such a high magnetic attraction force on the closing body side permanent magnet magnetic element 34 from that the closing body 15 is moved from the open position to the closed position. The operation of the permanent magnet magnetic element 33 , ie in particular its energization, is equally through the control device 24 controlled. The relevant explanations apply in connection with the control of the operation of the motor drive device 22 analogous.

Alternatively to that in the in 4 shown embodiment of corresponding electromagnetic magnetic elements or permanent magnetic magnetic elements, it is also possible on the housing side permanent magnetic magnetic elements 34 and closing body side electromagnetic magnetic elements 33 provided. It is also conceivable, both the housing part side and the closing body side electromagnetic or permanent magnetic magnetic elements 33 . 34 provided. The in the in Figs. shown embodiments 1 further comprises a closed position detection device 26 for detecting the closed position of the closing body 15 , The closing position detection device 26 is set to when detecting the closed position of the closing body 15 to generate at least one acoustic and / or optical closing position information and an output means 27 in which it is z. B. is a speaker and / or one, in particular multi-colored, LED, spend. The closing position detection device 26 comprises a realized via an implementation of photoelectric sensors, optical sensors 28 for detecting the closed position of the closing body 15 ,

The device shown in the embodiments shown in the figures 1 next to it includes a snack detection device 29 for detecting a bait bite. The snack detection device 29 is set up to detect a bitten bait 2 to generate at least one acoustic and / or optical bite information and the output means 27 issue. The snack detection device 29 therefore includes a sensor 30 for detecting a bait bite. The sensors 30 For example, the weight of the bait holder 12 arranged bait 2 capture, with bite-induced weight changes of the bait 2 To allow conclusions about bait biting. Similarly, the sensors 30 biting, on the bait 2 and the bait holder 12 detect acting forces, which also allow conclusions about a bait bite.

The snack detection device 29 can depend on the snack information, z. B. based on the detection of the weight of the bait 2 generate different acoustic and / or optical signals. With regard to the output of corresponding information in the form of optical signals, it is conceivable that the weight of a new, not bitten bait 2 can z. B. be signaled with optical signals of green color and / or permanently permanently output optical signals, the weight of a partially delivered bait 2 can z. B. are signaled with optical signals yellow color and / or output at a first flashing frequency optical signals is the bait 2 completely eaten, this can, for. B. be signaled by optical signals of red color and / or output at a higher compared to the first flashing frequency second flashing frequency optical signals. The same applies of course to the output of acoustic signals, in particular the frequency and / or the rhythm of a tone or a tone sequence depending on the weight of the bait 2 respectively on the bait 2 or the bait holder 12 acting forces are variable.

Contrary to the arrangement of the dispensing means shown in the embodiments shown in the figures on the housing part 3 , ie at the top of the cover element 6 , it is also possible that or an issue means 27 in an external mobile device, such. As a smartphone is integrated. In this case, the closing position detecting means 26 and / or the bite detection device 29 configured to communicate with the external mobile terminal and transmit the closed position information and / or the bite information to the external mobile terminal for output to the local output terminal. The communication is in particular radio-based, ie, for example realized by Bluetooth, WLAN, etc., which is why the closed position detection device 26 and / or the bite detection device 29 include corresponding radio-based transmitting devices.

It is evident in the recording room 5 a receiving chamber 31 formed, in which electrical and / or electronic components of the device 1 , ie in particular the control device 24 and corresponding detection devices 26 . 29 and optionally facilities for their electrical supplies, such. B. electrical energy storage are arranged. The reception chamber 31 offers protection of these components against external, ie in particular climatic and mechanical, influences.

Both the closed position detection device 26 as well as the snack detection device 29 are optional and for that by means of the device 1 realized basic principle of the invention is not absolutely necessary.

The 5 - 9 each show a schematic diagram of a device 1 for holding a bait 2 according to a further embodiment of the invention. Obviously, it is 5 around a perspective view of the device 1 , at 6 around a longitudinal section through the in 5 shown device 1 , at 7 to see an enlarged view of the 6 shown detail VII, at 8th for a view of the device 1 and at 9 to see an enlarged view of the 6 shown detail IX.

As can be seen in the 5 - 9 shown embodiment, that of the device 1 associated housing part 3 also be executed in several parts. The housing part 3 is here from an upper housing segment 3a and a lower housing part segment 3b executed. The housing part segments 3a . 3b can be secured to each other via unspecified retaining clips.

As it turned out 7 results, goes from the ring element 36 in the radial direction, an annular disc-shaped holding web 38 from. The jetty 38 supports one on the outside wall 10 of the housing part 3 ie the outer wall 10 of the lower housing part segment 3b , attached fuse element 39 from. The here also ring-shaped fuse element 39 is by means of a latching mechanism on the housing part 3 , ie the housing part-side outer wall 10 , attached. The locking mechanism is through the interaction of housing outer wall side locking elements in the form of locking projections not shown in detail and locking element side counter-locking elements in the form of recesses 66 realized in which the housing outer wall-side locking elements can lock. Of course, a reverse arrangement, ie housing outer wall side locking elements in the form of locking recesses and locking element-side locking elements in the form of locking projections, conceivable.

One below the jetty 38 formed area of the ring element 36 serves in the closed position of the closing body 15 as a contact surface for an outer peripheral side arranged on the closing body or trained, unspecified sealing element.

The fuse element 39 serves the captive arrangement of the closing body 15 on the housing part 3 , This is realized in that a securing element side, here angled extension 40 so in the between the housing part-side outer wall 10 and the radially inwardly offset inner walls 11 formed housing part side guide sections 13 that engages the closing body 15 due to one of the upper portion of the closing body side guide elements 14 radially projecting extension 41 prevented from leaving the guide section 13 to glide.

In 6 it can be seen that the of the closing section 16 of the closing body 15 outgoing areas 42 slightly inclined, ie, for example by 3 to 5 °, are executed, so that on the closing body 15 located water can flow radially outward.

In which a top side or front side of the housing part 3 , ie the upper housing part segment 3a , forming area is a cylindrical reception chamber 31 arranged. The reception chamber 31 has a cylinder-like, a receiving chamber volume 43 for receiving electrical and / or electronic components of the device 1 limiting reception chamber body 44 on. Obviously, the receiving chamber main body protrudes 44 in sections in the housing part side receiving space 5 ,

At one in the housing part-side receiving space 5 protruding lower portion of the receiving chamber main body 44 is a bait holder 12 for holding the bait 2 arranged.

The reception chamber 31 is detachable on the housing part 3 , ie here the upper housing segment 3a , attachable. The releasable attachment of the receiving chamber 31 on the housing part 3 is by positive interaction of housing side mounting portions 45 with receiving chamber body-side attachment portions 46 Educable or trained. The reception chamber 31 and the housing part 3 So are each with mounting sections 45 . 46 equipped, on their interaction is a stable or captive, yet releasable attachment of the receiving chamber 31 on the housing part 3 can be realized. As in particular by means of 9 results is under a positive cooperation of respective attachment portions 45 . 46 an at least partially interlocking or overlapping corresponding fastening sections 45 . 46 to understand.

The reception chamber 31 is rotatably supported between a mounting position and a release position on the housing part 3 arranged. In the attachment position, the housing-side attachment portions act 45 and the receiving chamber body-side fixing portions 46 form-fitting together, so that the receiving chamber 31 detachable on the housing part 3 is attached. In the release position, the housing-side attachment portions act 45 and the receiving chamber body-side fixing portions not together, so that the receiving chamber 31 from the housing part 3 is solvable. The attachment of the receiving chamber 31 on the housing part 3 can therefore by rotating movements of the receiving chamber 31 about an axis of rotation, which typically coincides with the central axis of the receiving chamber 31 coincides, relative to the housing part 3 produced and be lifted again. The reception chamber 31 can therefore by rotational movements relative to the housing part 3 be transferred from the mounting position to the release position, and vice versa.

As it turned out 9 results, the housing-part-side fixing portions 45 as one of an axially aligned cylinder-like portion 47 of the housing part 3 radially inwardly projecting ring segment disc element 48 with at least one of this axially projecting shoulder-like fastening projection 49 educated. The receiving chamber body-side fixing portions 46 are as one of a cylinder-like approach 50 of the receiving chamber main body 44 radially outwardly projecting ring segment disc element 51 with a to the housing-part-side fixing portion 45 formed fastening projection 49 corresponding, ie counter-trained or aligned, axially projecting shoulder-like fastening projection 52 educated.

To realize corresponding rotational movements of the receiving chamber 31 relative to the housing part 3 has the receiving chamber 31 in the area of an in 8th shown upper exposed deck section 53 a tool engagement area 54 on, in which a here T-shaped tool 55 with an engaging portion 57 can intervene positively. About how in 8th shown in the tool engagement area 54 engaging tool 55 can be rotational movements on the receiving chamber 31 transferred to the receiving chamber 31 from the mounting position to the release position, and vice versa to convict. The tool engagement area is visible 54 here with ring segment-shaped tool holders 58 formed, in which the cross-sectionally rounded designed tool-side engaging portion 57 can engage, allowing rotational movements of the tool 55 counterclockwise to rotational movements of the receiving chamber 31 run counterclockwise. The engaging section 57 arranged circumferentially opposite a stop portion 59 educated. Between the engagement section 58 and the stopper section 59 is a circumferentially extending gap space 60 formed over which the tool 55 into the tool engagement area 54 can be introduced in order to cooperate with it.

By the arrangement or design of the tool engagement area 54 in the area of an upper exposed deck section 53 the receiving chamber 31 is the tool engagement area 54 always accessible (from above). The geometric shape of the tool engagement area 54 is due to the shape of the tool 55 customized. The present is the geometric shape of the tool engagement area 54 such that a T-shaped tool 55 can engage form-fittingly at this, so that over by the double arrow 56 indicated rotational movements of the tool 55 Rotary movements on the receiving chamber 31 can be transmitted.

The tool engagement area is corresponding 54 in properly inserted into a manhole shaft state of the device 1 good, ie especially from above, accessible. By suitable shaping and dimensioning of a corresponding tool 55 It is not imperative that a user descend into the manhole to the receiving chamber 31 to be converted by appropriate rotational movements of the mounting position in the release position, or vice versa. The reception chamber 31 can therefore from outside the manhole of the housing part 3 dissolved and optionally removed from the manhole. This may be for control purposes, e.g. For example, determining whether bait baiting has taken place can be practicable so that controls can be considerably simplified and carried out considerably more swiftly.

Especially since the bait 2 about the at the receiving chamber 31 arranged bait holder 12 is held, the receiving chamber can 31 including bait holder 12 and baited bait 2 taken without entry into the manhole from the manhole, any bait bite recognized, possibly an exchange or replacement of or a bait 2 made and the receiving chamber 31 including bait holder 12 as well as baited bait 2 be brought back into the manhole.

The holding element sections 72a . 72b are bent in an L-shape. The holding element 72 thus has a (substantially) L-shaped geometric shape.

On the basis of in the 14 - 18 embodiments shown is still a particularly convenient attachment device 73 over which the housing part 3 , in particular detachably, on a wall of a sewer 4 , in particular a manhole, fastened, shown. The fastening device 73 includes a housing part 3 Outer peripheral side encompassing, annular, first fastener 74 , which over on the housing part 3 screwed fastening clips 76 on the housing part 3 is attached, and at least a second fastener 75 for fastening the first fastening element 74 and the attached housing part 3 on the wall of a sewer 4 or a manhole. About the fastening device 73 can be a, especially with regard to flood or Schwallwasserbedingte on the housing part 3 acting forces, stable attachment of the housing part 3 on a wall of a sewer 4 or a manhole. The attachment of the second fastener 75 on the wall of a sewer 4 or a manhole is over from the second fastener 75 outgoing or on the part of the second fastening element 75 , optionally threaded, horizontal or vertical holes 77 passing through fastening bolts 78 or screws realized, which, for. B. by walls or screws, stable in the wall of a sewer 4 or a manhole can be anchored.

Obvious is the fastening device 73 executed in several parts. To realize a buoyancy protection, the second fastening element comprises 75 one the housing part 3 on the upper side with the formation of a buoyancy protection sections overlapping fastener section 75a , The housing part 3 is thus protected against flooding or flood-related buoyancy forces and in its, in particular vertical, positionally stable on the sewer system 4 attached.

All components of the fastening device 73 are made of one or more mechanically stable and corrosion-resistant materials, eg. As stainless steels, or material structures formed or include such materials or material structures.

In the 16 . 17 is an optional monitoring device 83 for monitoring at least a part of the through the housing part 3 limited recording room 5 shown. The monitoring device 83 is so at the receiving chamber 31 arranged that the widest possible monitoring of the recording room 5 can be realized. The monitoring device 83 includes a suitable optical sensor for monitoring the receiving space 5 , The monitoring device 83 is in the in the 16 . 17 embodiments shown formed as infrared sensors or camera.

About the monitoring device 83 It is possible, all operations in the or a specific area or partial area of the recording room 5 to record and evaluate. In particular, rodent-related processes can be quantitatively and / or qualitatively recorded and evaluated or assessed. Quantitative and / or qualitatively monitored processes of particular interest are, for example, access by rodents to the receiving space 5 , Exits of rodents from the recording room 5 , the behavior, ie in particular the Anbiss- and / or movement behavior, respectively in the recording room 5 Rodents in the reception room 5 etc. In general, the frequency of the recording room 5 Quantitatively and / or qualitatively recorded and evaluated or assessed per specific time unit. Because of the monitoring device 83 Obtained monitoring information or data of course via a via a suitable communication device 91 trained, in particular radio-based, communication connection to a user-side, in particular mobile, external terminal 92 can be transmitted, can be via a corresponding monitoring device 83 a "monitoring" of all processes in the recording room 5 without the need for entry into the device 1 stocked manhole or in the with the device 1 equipped sewage system 4 realize. The communication is useful radio-based, ie, for example, realized by Bluetooth, WLAN, etc., which is why the monitoring device 83 a corresponding radio-based transmitting device (not shown) comprises or is connected to such.

The monitoring device 83 is about one in the receiving chamber 31 arranged rechargeable electric energy storage 84 supplied with electrical energy. In the energy storage 84 it is an electrochemical energy store in the form of a rechargeable battery. It would also be conceivable to use an inductive, ie one by means of electromagnetic induction, rechargeable energy storage.

On the basis of in the 14 - 17 the embodiment shown is also a section surface structuring 85 of the dome-shaped or spherical segment-shaped closing body 15 to recognize. The surface structuring 85 facilitates a rodent over the closing body 15 access to the bait platform 8th , The surface structuring 85 is by a step or rib-like structure of the circular disc-shaped portion of the spherical segment-shaped closing body 15 trained and offers a closing body 15 entering rodent stop or liability. The surface structuring 85 inhibits or prevents slipping of the rodent from the closing body 15 and thus serves as an "entry aid" for access to the bait platform 8th , Of course, a corresponding surface structuring serves 85 vice versa also in the sense of an "exit aid" for leaving the bait platform 8th , Next is on the part of the closing body 15 an annular section 86 existing, which also serves as a corresponding "entry help" or "exit help".

In 15 is also one by one from the bait platform 8th angled, especially vertical, protruding wall 88 limited area 87 for a bait 2 shown.

That in the in the 19 . 20 embodiment shown shows a special storage of a corresponding energy storage 84 , The energy storage 84 is on one at one in the reception room 5 projecting floor section 93 the receiving chamber 31 (releasably) fixed floor plate 94 stored. The attachment of the bottom plate 94 at the bottom section 93 via unspecified mounting screws (see. 20 ). Obviously there is a sealing element 96 in the form of a sealing ring between the bottom plate 94 and the bottom section 93 , Another unspecified sealing element is located between the receiving chamber 31 and housing part 3 ,

The bottom plate 94 is with angled, especially vertical, projecting walls 95 provided, which has a receiving area for the energy storage 84 limit. The energy storage 84 can typically be accurately positioned in the receiving area. The bottom plate 94 including the arranged on this energy storage 84 can insofar as separate to the receiving chamber 31 fastenable assembly are considered, which, for. B. in the context of an exchange or recharge of the energy storage 84 , in a simple way from the receiving chamber 31 dissolved and can be attached to this again.

Obvious is the monitoring device 83 as well as the communication device 91 side of the energy storage 84 on the bottom section 93 arranged. For the monitoring device 83 is the bottom section side an opening 95 intended.

On the basis of in the 21 . 22 shown embodiments is another way of movably mounting a closing body 15 by means of a flap device 89 recognizable. A corresponding flap device 89 comprises according to the in 21 shown embodiment, relative to the bait platform 8th movable, in particular pivotable, stored flap element 90 which in an open position so from the bait platform 8th moved away is that the bait platform side limited passage opening 9 is released, and in a closed position shown in broken lines against the bait platform 8th is moved that the bait platform side limited passage opening 9 is closed. The closing body 15 can here in the form of a corresponding flap element 90 integral part of the flap device 89 be. Of course, it would also be possible to have a separate closing body 15 on a corresponding flap element 90 to fix. The closing body 15 may be formed as a float or at least include a float.

Based on the in 22 shown embodiment can be seen that a corresponding flap device 89 also several flap elements 90 which may be in a respective open position so from the bait platform 8th are moved away that the bait platform side limited passage opening 9 is released, and in a respective closed position shown in dashed lines against the bait platform 8th are moved, that the bait platform side limited passage opening 9 through the flap elements 90 is closed together. In the in 22 shown embodiment are on respective flap elements 90 respective closing body 15 arranged.

On the basis of in the 23 to 26 shown embodiments can be seen that in the housing part 3 several bait platforms 8th can be arranged. In each case, at least one closing body 15 provided which is relative to at least one bait platform 8th is movably mounted, wherein the closing body 15 in an open position such from the respective at least one bait platform 8th is moved away, that the respective at least one bait platform side limited passage opening 9 is released, and in a closed position against the respective at least one bait platform 8th is moved, that the respective at least one bait platform side limited passage opening 9 is closed. The described principle of the hermetically sealing closure of a bait platform side limited passage opening 9 via a closing body moved into a corresponding closed position 15 So here is equally valid.

Obvious are respective bait platforms 8th arranged above or below each other. Several bait platforms 8th can be arranged in parallel at least in sections. Between two adjacently arranged bait platforms 8th is a gap defining an intermediate level 97 educated. The gaps 97 communicate via respective bait platform side limited passage openings 9 together; There is therefore a passageway between the individual bait platforms 8th ie from a "lowest" bait platform 8th up to a "top" bait platform 8th ,

Corresponding spaces 97 cause a flow-related "sedation", generally influencing the flow, in the housing part 3 ascending water. That in the housing part 3 Incoming and in this ascending water must therefore make its way over several intermediate levels upwards, which leads to a "calming" of the flow of water. Respective bait platforms 8th In addition, at least in sections, the flow, in particular the type of flow or the flow velocity, can flow from or along the housing part 3 ascending water surface structuring (not shown), e.g. B. in the form of flow-influencing ribs and / or beads, be provided.

Obvious are those by respective bait platforms 8th limited passage openings 9 arranged offset relative to each other. Due to the staggered arrangement of respective passage openings 9 is also a "reassurance" in the housing part 3 ascending water possible. The staggered arrangement of respective through holes 9 also facilitates the movement of a rodent between respective spaces 97 or intermediate levels.

Based on 24 . 25 is to realize that a bait platform 8th at least in sections, with an inclined or curved or curved relative to at least one further, in particular adjacent, arranged further bait platform 8th extending bait platform section may be formed. By appropriate inclined or curved or curved courses of corresponding bait platforms 8th may also affect the flow of in the housing part 3 ascending water can be realized. Inclined or curved or curved courses of corresponding bait platforms 8th also facilitate the entry and exit of rodents between respective spaces in the sense of ascent and descent ramps 97 or intermediate levels.

As in 23 exemplary for the lowest bait platform 8th indicated as a further measure to influence the flow of in the housing part 3 rising water, a bait platform 8th be formed at least in sections with these dursetzenden, unspecified hole-like openings or perforations. Corresponding apertures, generally similar to a hole (sheet) structure, can "dampen" and thus "calm down" the flow of rising water. The openings are recognizable in addition to respective passage openings 9 present and differ in particular in their size, in particular their diameter, of respective passage openings 9 ; the openings are small compared to respective through holes 9 , For example, round openings may have a diameter between 50 μm and 3 mm, in particular between 100 μm and 2 mm.

Generally, ie basically independent of the provision of multiple bait platforms 8th , it should be noted that in case of inflow or rising of water in the or in the housing part 3 due to the given volume (internal volume) and the tightness of the housing part 3 in the housing part 3 forms a counter-pressure, which is opposite to the inflowing or rising water respectively counteracts the influx or rising of water. This is due to the fact that in the housing part 3 Air is compressed by the inflow and rising of water. The rising of water in the housing part 3 is therefore increasingly difficult due to the forming counter-pressure.

Based on the in 25 As shown, it can be seen that at least one bait platform 8th at least partially spirally or helically at least partially through the housing part 3 may be formed extending. About a corresponding spiral or - similar to a spiral staircase - helical trained bait platform 8th can be a in the housing part 3 Penetrated rodent in a simple manner within the housing part 3 move, z. B. to a bait 2 to get. Spiral or helical bait platforms 8th may also affect the flow of in the housing part 3 have rising water.

Are visible in the 23 to 26 different ways of storing corresponding closing body 15 shown. These can of course be combined arbitrarily. Also, the number and arrangement of respective closing body 15 on respective bait platforms 8th is of course purely exemplary and can be combined arbitrarily. The same applies, of course, for the number and arrangement of respective bait platforms 8th ,

For all embodiments, that the housing part 3 with stiffening structures to increase the mechanical stability of the housing part 3 can be provided. Corresponding stiffening structures can, for. B. ring or rib-like, be formed. Corresponding stiffening structures can be used as separate components which correspond to the housing part 3 to be attached or to be connected to this, be present or integral with the housing part 3 be educated.

All embodiments of the device shown in FIGS 1 respectively one or more features of the embodiments shown in FIG. 1 can be combined with one another as desired.
