EXPANDABLE PEST VALVE AND METHOD FOR ASSEMBLY

TECHNICAL FIELD

The present invention relates to a pest control system, preferably rats in drainage systems, and comprises a trap with a housing and a method of removably positioning and retaining at least the trap housing in the drainage system after mounting therein.

BACKGROUND

Today's modern society has problems with pests, especially rats, which are found in the community's drainage system and in similar places or in passages through which the rats can move.

Pests spread diseases and cause major damage, so the need to control these animals is increasing. There are known ways to fight pests by placing poison and usually by traps. Known traps have the disadvantages that animals that the poison is not intended can get it into the body, either by ingesting the poison directly or by devouring pests that have died from the poison. Other animals may be trapped and die and / or injured in known traps instead of the pests. In some cases, known traps cannot be used to fight multiple pests at a time, as known traps can often only fight one pest at a time, i.e. when a first pest is trapped in the trap, the trap must be deactivated, emptied manually and subsequently reinforced. manually, ie reactivated for reuse.

Certain known traps are only suitable for a particular application, e.g. as a box of a predetermined size, e.g. on the enclosure and / or trap entrance opening for a particular type of pest. Furthermore, a classic blow trap often has fragrant baits, e.g. food that not only attracts pests, but also other animals of the same size. Famous traps included

DK 2020 70011 A1 predetermined sizes / dimensions cannot be placed anywhere, as they must be sized to fit where they are placed.

DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS

In FIG. 1 to 10G, a system 4 and a trap 10 and associated interacting parts for controlling pests, in particular rats, are shown in drainage systems 1,

DK 2020 70011 A1 which system 4 / trap 10 has at least partially adjustable size / width / radius HR, HR '. Radius HR is the smallest size / width / radius the system / trap can have, while radius HR 'is the largest size and / or width and / or radius that the system / trap can have. The system 4 is constructed in a module-like manner, comprising several removably interconnected and functionally interacting parts 10, 90, 100, 120. The system 4 comprises movable and fixed parts which can be combination of composite internal parts to a larger system 4 and / or comprises at least one external separate part 90, 100 operatively / functionally interconnected by electricity, pneumatics and / or hydraulics and / or comprising a combination of such parts.

The system 4 comprises a trap 10 with a housing 20. The housing 20 is cylindrical in FIG. 1, 4-6, 8-9 and oblong, but may be at least partially square, e.g. rectangular and / or more compact or thicker in design with adjustable width / radius HR, HR '. The system 4 is adapted for removable / removable mounting in different size drainage pipes 3 in drainage systems 1. The system 4 / trap 10 is adapted for removable positioning and holding of the housing 20 within drainage pipes 3, preferably an inspection pipe 2 in drainage systems, of different size / shape. after the removable mounting therein. The shape and size of the housing 20 are at least partially adjustable in relation to the internal design 2 'of the inspection tube, ie. size, inside diameter / radius and / or shape; FIG. The trap 10 may in one aspect comprise deterrent, non-lethal agents, e.g. chili, which can be spread out as powder / vapor and / or stroboscope light via suitable headlamps and / or loud sounds through speakers, which are triggered when a rat is detected to scare the rat away.

The system 4 / trap 10 comprises at least one control device 30 having an adapted or optimized control radius BR. The control radius BR defines the physical distance relative to the trap 10 within which one or more rats can move, be detected and fought, corresponding to a

DK 2020 70011 A1 action radius. The trap control radius BR can be adapted to different needs, ie larger or smaller drainage systems and / or various selected locations in a drainage system 1. The system 4 / trap 10 comprises at least one sensing means 40 which is set to activate the control means 30 when a rat is detected via touch or touch-free, e.g. via infrared radiation (IR), within the combat radius BR. The system 4 / trap 10 comprises at least one control unit 90 which is set to control the control device 30 via the sensing means 40 by activating the control device when a rat is detected within the control radius BR. The system 4 / trap functionally comprises at least one power supply 100 to the control unit 90. The power supply is in one aspect a battery 100. In another aspect, the power supply 100 may be an external unit or an internal unit for the trap 10. The control device 30 is in a lethal manner for the rat. aspect, at least one insert and extendable spear, preferably multiple spears, which cross legs in the rat, e.g. its back without penetrating the skin of the rat completely without hitting the drain pipe 3 and / or its bottom 3 ', see fig. 8th

The system 4 / trap 10 comprises at least one electrically or mechanically actuable fastening mechanism 50 which is adapted to detachably position and hold the housing 20 within the inspection tube 2 of the drainage system 1 after mounting therein. The housing 20 comprises a longitudinal axis A. The fastening mechanism 50 is set to increase a portion of the radius HR of the housing relative to its longitudinal axis A until the fastening mechanism is at least partially in contact with the inside tube 2 'of the inspection tube. The fastening mechanism 50 is also set to reduce a portion of the radius HR 'of the housing relative to its longitudinal axis A until the fastening mechanism is not in physical abutment against the inside 2' of the inspection tube. The fastening mechanism 50 is set to increase a portion of the smaller radius HR of the housing relative to its longitudinal axis A to a larger radius HR 'after the trap 10 is inserted into the interior of the inspection tube, i. until the attachment mechanism is at least partially abut against the inside tube 2 'of the inspection tube and is set to reduce the enlarged

DK 2020 70011 A1 part of the housing 20, ie. its larger radius HR 'relative to its longitudinal axis A to a smaller radius HR, i.e. until the fastening mechanism is no longer in restraint against the inner tube 2 'of the inspection tube for removing the trap from the inspection tube. In one aspect of the system 4 / trap 10, the control unit 90 is set to activate the securing mechanism 50 by controlling the power supply 100 thereto or not for deactivating the same.

Detachable mounting of the system / trap 10 in the inspection tube 2 is achieved by the fixing mechanism 50 being adjustably positionable and holding the housing 20 within the inspection tube by means of mold and / or force grips and detaching the housing from the inside of the inspection tube. This can be achieved since, in one aspect, the fastener 50 comprises at least one retractable pin / pin 60 which is adapted to shape / force grips having a corresponding recess or cavity on the inner side 2 'of the inspection tube when the pin or pin 60 of the fastener mechanism which can being spear-like, is projected radially from the smaller radius HR of the housing at a certain distance from the housing 20 to at least partially abut the inside of the inspection tube 2 'corresponding to the larger radius HR of the housing'. This can be achieved in another aspect in that the fastening mechanism 50 comprises one or more movable plates 70 adapted for engaging and disengaging mold and / or force grips having a corresponding or complementary surface on the inside of the inspection tube 2 'when the fastening plate 70 is displaced. from the smaller radius HR of the housing at a certain radial distance from the trap housing 20 to at least partial abutment towards the inside of the inspection tube corresponding to the larger radius HR of the housing '.

The system 4 / trap 10 comprises at least one rangefinder 80 which is set to detect or sense the location of the trap 10 relative to a bottom 3 'of the drain 3 below the inspection tube 2. The rangefinder 80 ensures that the trap housing 20 is not moved too far down in the drainage system 1, so that upon release or activation of the trap 10, when a rat is detected, the trap's spike 30 is not extended and collides with the drain bottom 3 '. This security can be achieved by the system 4 / trap 10 comprising at least one spacer 110 (FIG.

DK 2020 70011 A1

1, 4, 5) are set to define the vertical position of the trap relative to the drain bottom 3 'below the inspection tube 2 when mounted therein. This solution also simplifies the fitting of the trap 10 and enables the trap radius BR to be optimized without manual control, e.g. measurement. Simplified mounting of the trap 10 is also achieved by the spacer 110 being set to be releasably attached to the spear 30 of the control device in the extended position and the spear and spacer being aligned so that the spacer is detached from the spear in the spear position.

For the function of the fastener mechanism 50, it comprises at least one drive device 51. The drive device 51 is adapted for adjustable insertion and extension of the fastener mechanism, i.e. one or more of its pins / pins 60 or one or more plates 70 in the direction towards and from the longitudinal axis A of the housing by means of electrical, pneumatic and / or hydraulic and / or manual and / or mechanical drive. An example of mechanical drive is at least one gears in movable engagement with at least one gear that can be operated manually or with a controllable electric motor. The pin / pin 60 can be pushed out or into more or less straight outward radial direction as in FIG. 4 or folded out of the trap housing 20, similar to a camera stand on legs, the legs of which are formed by one or more pins / pins 60 hinged at an upper end located farthest from the control device 30 of FIG. 1, which is unfolded / angled outwardly with the other / lower end closer to the control device and the spacer 110 of FIG. 1 at an angle from the housing 20 and extends downwardly toward the lower drain pipe 3 and is "positioned" / supported with the bottom unfolded end against an edge / flap or cavity / recess 61 at a suitable height on the inside of the inspection tube 2 '. One or more plates 70 may be pushed out or into more or less straight outward radial direction or folded out of the trap housing 20, e.g. as a movable wall that sits on fixed radially directed arms and is more or less evenly radially projected from or toward the housing 20 (Figs. 4 and 7-9), or as a movable wall that sits on hinged but fixed as parallelograms;

DK 2020 70011 A1 movable assembled arms and folded out from or in towards the housing 20 in a partially rotating / curved motion.

The present invention also relates to a method of removably mounting the trap 10 within the inspection tube 2 in drainage systems 1. The method comprises introducing the trap 10 into the inspection tube (Figure 5), adjusting the vertical position of the trap with respect to the bottom of the drain pipe below the inspection tube, thus optimizing the trap radius BR of the trap (Fig. 6) and securing the trap removably to the inspection tube 2 (Figs. 7-9). The method comprises in one aspect that the detachable attachment of the trap 10 is effected by activating the attachment mechanism 50, until the attachment mechanism is at least partially abutting the inside of the inspection tube 2 '(Figs. 4, 7-9). The method further comprises an aspect of positioning the control unit 90 and / or the power supply 100 to the trap 10 removably above the trap (Fig. 8). This detachable location of the power supply 100 is obtained e.g. with a suspension / binding device 120 (see Figures 1 and 8), said suspension device 120 having a variable length by means of an adjustable mechanism 121 which can be telescopic, preferably via pipe fitting, in order to be adapted in size / length to inspection pipes 2 of different sizes, e.g. various internal diameters. The method may further comprise placing the power supply 100 and the control unit 90 to the trap 10 removably by means of hooks or hooks 91 which are hooked over the suspension device 120 above the trap 10, ie. its housing 20 (Fig. 8). The method also includes activating the trap 10 after mounting / placement thereof.

The method further ensures proper removable mounting and placement of the trap 10 by including extending the control device spear 30 and holding it in this position, after which the spacer 110 is mounted on the spear (Fig. 1), and the trap is then inserted into the inspection tube 2 with spear and spacer ( Figures 4-6) until the spacer 110 comes in

DK 2020 70011 A1 abuts against the drain pipe 3 under the inspection pipe (Fig. 6), and the spear is then pushed in so far back into the trap that the spacer can be detached from the spear 30 and reinforcement of the trap can be done (Figs. 8, 9). The method can also ensure proper removable mounting and positioning of the trap 10 by including measuring the distance to the drain pipe bottom 3 'below the inspection tube 2 via / using at least the distance meter 80 for recording and sensing the trap location relative to the drain bottom 3' below the inspection pipe. This measurement provides a double check of the distance to the drain pipe bottom 3 'below the inspection tube 2 that the trap control device 30 is correct relative to its control radius / distance BR. The adjustable size / width / radius of the system and trap can be obtained via the fastening mechanism 50 and its drive 51 and the skewer or pin or pin 60 which is retractable. Alternatively, the adjustable size / width / radius of the system and / or trap can be obtained by means of the fastening mechanism 50 and its drive 51 and the plate (s) 70, which are insertable / extendable (s) by straight and / or inclined outward / the arm (s) and / or via the hinged parallelogram which swings out the plate (s).

The spacer (s) 110 (if more than one spacer is used, for example as stacked tubes, for example, of paper, of the same and / or different sizes / lengths for modular and controllable construction of a desired height of a stack ( spacer) to the system / trap control device so that it is adjustable in size, for example in length and / or height to fit the trap in different types of pipes, different depth / length pipes and / or other uses in addition to drains.

The adjustable size / width / radius of the system and trap can be obtained via the fastening mechanism 50 and its drive 51 and the skewer or pin or pin 60 which is retractable by the projecting parts being liquid or hydraulically suspended so that they can be adapted to various sizes, shapes and diameters on the inside of the pipe 2 ', e.g. by postponing

DK 2020 70011 A1 for installations and until a certain amount of construction power is achieved, why e.g. the spear 30 of FIG.

is projected with different lengths to fit the curvature / radius of the drain pipe bottom 3 '. Corresponding liquid suspension can be obtained for the fastening mechanism 50 and its drive 51 and the plate (s) 70 which are retractable / extendable using air or hydraulic fluid, e.g. in the expandable / inflatable bag-like or piston-like part 71 of FIG.

7. In FIG. 4 and 7, the adjustment of the size / width / radius of the trap 10 is shown in relation to larger pipes 2, where the spear 60 and / or plate 70 is extended with a longer distance HR ', since the trap is inserted into a larger pipe than in FIG. 8, 9 and 10G. The plate 70 and the pin 60 are in various aspects partly made of resilient material, e.g. of rubber, and / or partially of hard material, e.g. metal.
