Description

Sensor intelligent multiple protective cover

Technical Field

The invention relates to the technical field of sensor protection devices, in particular to an intelligent multiple protection cover for a sensor.

Background

The sensor is equipped with the protection casing in the manufacturing process and when leaving the factory, and is usually simpler and easier, for example, the cover made of plastic and other materials is sleeved. After the user purchases the sensor, when in use, the cover is generally directly taken off without special management, but is directly thrown away. In some special scene applications or some special sensor classes, the conventional method has a major drawback.

Especially the sensor related to water quality monitoring has the following defects:

(1) the measurement part of the electrochemical dissolved oxygen sensor, polarography or galvanic cell sensor is provided with a breathable film, and if the sensor is used or protected improperly, the sensor is very easy to break, for example, the sensor can not be used directly due to the displacement or the breakage of the breathable film when the sensor is touched by accident or falls on the ground;

(2) after the fluorescence method dissolved oxygen sensor is used, if no special attention is paid in the later use or maintenance process, the key parts of the sensor are not covered by black sleeves or cloth and the like in time, the fluorescent layer can be directly consumed, so that the normal service life of the sensor is seriously damaged, and the service cycle can be extremely shortened.

In the traditional application process, the protective cover is directly sleeved, so that the following problems in use exist:

(1) when the sensor is used, the protective cover needs to be detached, the sensor is generally discarded or lost after a short period of time, the sensor is not provided with the protective cover in the whole using process, the conditions of accidental falling, accidental touch and the like of the sensor at the later stage cannot be eliminated, and certain hidden danger exists;

(2) the water body monitoring sensor is directly pulled up from water during daily maintenance or checking, the operators are generally not professional sensors, the sensors are applied to a large variety on site, the operators cannot specifically identify and use the sensors, if the fluorescence method dissolved oxygen sensors are used, the sensors can be placed in the water body again, the sensors can be placed for a long time in the sun accidentally, the service life of the sensors is greatly shortened, or the measurement is inaccurate;

(3) in the case of aquaculture and other scene applications, such as the use of sensors in prawn culture, when one manufacturing operation is finished, the sensors need to be collected and maintained and then stored in good condition during the period of time when the second manufacturing operation is not started. However, after being collected, farmers generally place the collected fish in a certain corner randomly and wait for the fish to be used again, and the protective cover is lost early, so that the improper use of the sensor is caused, and the service life of the fish is seriously threatened;

(4) due to the fact that the water body condition is complex, particularly the aquaculture water body, the water body biological excrement and the like exist, the water body biological excrement and the like can be adsorbed on the key measuring position of the sensor, and therefore irregular cleaning or maintenance is needed, more uncertain factors are added, and the probability that the sensor is not used properly is greatly increased.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The following disclosure provides different embodiments, or examples, for implementing different features of the invention. The components and arrangements of the specific embodiments are described below to simplify the present disclosure.

As shown in fig. 1, the intelligent multiple protective cover for the sensor comprises a protective cover body 10, wherein a control box body 105 is arranged at the lower part of the protective cover body 10, a dirt collecting disc 103 with an inward concave plane is arranged on the upper surface of the control box body 105, and a plurality of mounting posts 104 are arranged at the edge of the dirt collecting disc 103.

The protective cover comprises a protective cover body 10 and is characterized in that a lifting rotating column 101 is arranged on the central axis of the protective cover body 10, the lifting rotating column 101 penetrates through a hole formed in the central area of a sewage receiving disc 103, and a cleaning disc 102 is arranged on the lifting rotating column 101.

The cleaning disc 102 and the lifting rotary column 101 can be lifted or rotated synchronously, and the cleaning disc 102 is arranged at a position right below the measuring part 201 of the sensor 20.

In this embodiment, the shield body 10 is installed and disposed below the sensor 20, and the upper end portion of the mounting post 104 is clamped and fixed to the lower end edge of the sensor 20.

The top end of the mounting column 104 is provided with a buckle and a round hole for fastening and mounting the shield body 10 and the sensor 20, and the shield body 10 can be fixed below the sensor 20 after being bound around the buckle part by an external circular coil.

The control box body 105 is made of soft plastic and can play a role in falling prevention. The measuring part 201 of the sensor 20 can not be damaged when the sensor is carelessly dropped in the using or maintaining process, and the sensor is particularly suitable for the dissolved oxygen water sensor with the air-permeable film.

In this embodiment, the number of the mounting columns 104 is 4, the mounting columns are uniformly distributed, the gap between adjacent mounting columns 104 is large, the water body is allowed to pass through the gap and flow through the measuring part 201, and when a part of the sensors require water flow to reach a certain flow rate, better detection conditions are conveniently achieved. The mounting posts 104 are not recommended to be arranged too many, preferably 3-4.

The lifting/lowering rotary column 101 has a cylindrical structure, and the diameter thereof is smaller than that of the cleaning disk 102. The diameter of the cleaning disc 102 is larger than the diameter of the measuring part 201 of the sensor 20. The lifting rotary column 101 may be a solid or hollow structure, and may drive the cleaning disc 102 to rotate or lift together, the length of the lifting rotary column 101 is controlled to be just above the lower portion of the sensor 20 when the lifting rotary column is lifted, and at this time, the cleaning disc 102 covers the measuring portion 201, so that the measuring portion 201 is in a closed state. If the sensor 20 is exposed, the measuring portion 201 will not be exposed to light.

In this embodiment, after the cleaning disc 102 is controlled to be pushed against the measuring part 201, the cleaning disc 102 can be further controlled to rotate, so as to brush the measuring part 201. The part of the dirt washed away from the lower end of the sensor 20 will fall into the dirt receiving tray 103.

The sewage receiving plate 103 is concave, a vertical wall body is arranged around the edge, most of the middle area is planar, the height of the vertical wall body is limited, and the sewage is prevented from being accumulated too much. Preferably, the central planar area may be slightly inclined, high in the middle and then gradually lower in the peripheral direction.

As shown in fig. 2, the edge of the dirt collecting tray 103 is further provided with a plurality of dirt outlets 1031.

In this embodiment, the bottom surface of the notch of the dirt outlet 1031 is parallel to or slightly lower than the plane of the dirt collecting tray 103, and after various dirt is stacked on the dirt collecting tray 103, the dirt can be passively dropped out from the dirt outlet 1031 under the conditions of the flushing action of water flow and the like, if the dirt is not completely dropped out, the dirt is not affected, and in some occasions, such as aquaculture, the main components of the various dirt may be further analyzed irregularly for symptomatic treatment.

As shown in fig. 2 and 3, and in conjunction with fig. 4, the edge of the cleaning disc 102 is provided with a raised adhesive tape ring 1023. In this embodiment, the rubber strip ring 1023 is made of soft material, and when the cleaning disc 102 is pushed against the sensor 20, the rubber strip ring 1023 can be in closer contact with the measuring part 201.

A plurality of irregular convex strip-shaped soft rubber strips 1021 are arranged in the cleaning disc 102. In this embodiment, the soft rubber strip 1021 is formed by two arc-shaped splicing shapes in opposite directions. When the cleaning disc 102 is rotating, the soft rubber strip 1021 brushes the measuring part 201. Since the rotation speed of the cleaning disc 102 is controllable, if brushing is performed, it is slowly rotated.

In some applications of the water quality sensor, such as an electrochemical dissolved oxygen sensor, a certain flow rate of the water is required to meet the detection condition, so as to obtain the measurement result more accurately, if the sensor 20 is placed in a substantially stationary water body, the lifting rotary column 101 may be controlled to ascend, stop at a position within a certain distance range from the measurement portion 201, and then rotate rapidly, so that the water in a part of the area below the sensor 20 may be stirred under the combined action of the soft rubber strip 1021 with a certain height, so as to promote water circulation, and thus, the measurement accuracy of the sensor 20 is improved.

Therefore, in this embodiment, the cleaning disc 102 is abutted against the measuring part 201 by the engagement of the rubber strip ring 1023 and the soft rubber strip 1021, and can be used as a fluorescence sensor by providing a light-proof function in the case of maintenance or taking up the sensor 20 from a water body; if the cleaning disc 102 is controlled to rotate slowly, the device plays a role of brushing a measuring part of the sensor and is suitable for various sensors with air-permeable films or other sensors; if the cleaning disc 102 is controlled to rotate rapidly, the water body stirring effect is achieved, and the method is suitable for various electrochemical dissolved oxygen sensors.

As one of the practical ways, the soft rubber strip 1021 can also be made of other plastic materials, and a soft brush is arranged at the upper end thereof.

A plurality of drain holes 1022 are disposed in the cleaning disc 102. A number of triggers 1024 are disposed on the glue strip ring 1023. In this embodiment, the trigger 1024 is a trigger switch, the trigger 1024 is fixedly disposed on or embedded in the upper end surface of the rubber strip ring 1023, when the cleaning disc 102 is lifted, the rubber strip ring 1023 pushes the measuring portion 201 to trigger the trigger 1024, and then a trigger signal is fed back to an intelligent controller disposed in the control box 105, wherein the intelligent controller at least comprises a microcontroller module and a power supply module. The trigger 1024 is connected to the microcontroller module.

In this embodiment, the power module and the power source of the sensor 20 are independent of each other, and can be adapted to various sensors.

A plurality of light detectors 1025 are disposed on the cleaning plate 102. In this embodiment, the light detector 1025 employs a photo-resistor and its peripheral circuits. The light detector 1025 is connected to the microcontroller module. The light detectors 1025 are disposed on the planar edge regions of the cleaning plate 102, and portions of the light detectors 1025 may be disposed on the upper surface of the bead ring 1023.

When the sensor 20 is in maintenance or the like, it is fished out of the water body, and at this time, the light detector 1025 captures the obvious change of the light and feeds back the signal to the microcontroller module in time. The intelligent control ware in the control box body 105 will start and control the lift column 101 rises, works as the washing dish 102 withstands measuring portion 201 stops, in the closely effect of adhesive tape ring 1023 down, measuring portion 201 will not be shone by light, plays the lightproof effect. This function applies to sensors of the fluorometric principle class.

The intermediate region of the cleaning disc 102 is also arranged with a tilt detector 1026. In this embodiment, the inclination detector 1026 is connected to the microcontroller module. The inclination detector 1026 is used to capture the sudden change of the inclination angle of the sensor, and when the sensor 20 is in maintenance or in use and abnormal conditions such as sudden drop occur, the inclination detector 1026 captures a signal and feeds the signal back to the microcontroller module in time.

If the inclination detector 1026 detects that the sensor is always in a certain range of variation state, and the light detector 1025 detects light, the lifting rotary column 101 is lifted, and the cleaning disc 102 is pressed against the measuring part 201 to protect the sensor 20.

After the sensor 20 maintains a certain angle range and maintains a certain period of time, if the light detector 1025 cannot detect light at the same time, the lifting rotary column 101 slowly descends to expose the measuring part 201 for normal measurement.

As one of the implementable manners, the inclination detector 1026 may also be an acceleration sensor.

According to the intelligent multiple protective cover for the sensor, the protective cover with the control box body is arranged under the sensor, so that the situations of abnormal falling and the like in the using or maintaining process can be prevented, the protective effects such as falling and the like are achieved, the intelligent multiple protective cover for the sensor is obviously different from the traditional sleeved protective cover, and the normal use is not influenced; is more suitable for various sensors with breathable films.

According to the intelligent multiple protective cover for the sensor, which is provided by the invention, the lifting rotary column and the cleaning disc are arranged, the intelligent multiple protective cover can be used for jacking up and shielding the measuring part of the sensor in various application scenes, and the sealing effect of the rubber strip ring is combined, so that the intelligent multiple protective cover has a light-proof effect in the use or maintenance process, and is suitable for various sensors adopting a fluorescence method.

According to the intelligent multiple protective cover for the sensor, the irregular soft adhesive tape on the lifting rotary column and the cleaning disc can scrub the measuring part at the bottom of the sensor by controlling the rotating speed, so that the dirt adsorption is reduced, the measuring precision of the sensor is improved, and the service life of the sensor is prolonged.

The intelligent multiple protective cover for the sensor can promote water circulation and is suitable for part of sensors needing a certain flow rate; will wash the dish and push up to being close to the sensor bottom, nevertheless still keep certain distance, control and wash a dish fast revolution, under the combined action of irregular soft adhesive tape and blowoff hole, can stir partial water to promote the water and satisfy the detection condition, obtain more accurate measuring result.

The intelligent multiple protective cover for the sensor can be used for collecting dirt for subsequent analysis, is used for collecting a small number of cleaned dirt by arranging the concave dirt collecting disc with the vertical wall body with a certain height, and simultaneously avoids a large amount of dirt from being accumulated by arranging the dirt outlet.
