Description

Technical Field

[0001] This disclosure relates to the technical field of leak detection devices, and more specifically, to a leak detection device and its protective housing. Background Technology

[0002] In related technologies, water droplet sensors typically consist of two bare printed circuit board wires that cross each other but are isolated from each other by air. When immersed in water, the water triggers the two wires to conduct. When a water pipe leaks in the production line, the water first flows into a pit near the leak point. A leak detection device is installed in the pit, and the water accumulation triggers a switch to issue an alarm promptly. However, because the trigger ends of the two wires are unprotected, they are easily damaged, leading to conductivity failure, or the conductive ends may touch a conductive object, causing a false alarm. Utility Model Content

[0003] The purpose of this disclosure is to provide a leak detection device and its protective housing to at least partially solve the technical problems existing in the related art.

[0004] To achieve the above objectives, according to a first aspect of this disclosure, a protective housing for a water leakage detection device is provided, comprising:

[0005] An insulating housing having an opening and water passage holes provided on the side wall of the insulating housing.

[0006] An insulating mounting plate is mounted on the insulating housing and covers the opening. The mounting plate has mounting positions for mounting the detection element of a leakage detection device, such that the two detection electrodes of the detection element extend into the interior of the insulating housing.

[0007] An insulating protective cover is installed on the outside of the insulating mounting plate and can shield the mounting position.

[0008] Optionally, the mounting position includes a groove, and the groove is provided with a mounting hole that penetrates the insulating mounting plate, the mounting hole being used to mount the detection body.

[0009] Optionally, the side wall is provided with one of a connecting buckle and a connecting groove, and the insulating mounting plate is provided with the other of a connecting buckle and a connecting groove, wherein the connecting buckle and the connecting groove are fastened together.

[0010] Optionally, the insulating mounting plate is provided with two connecting buckles, which are arranged along a first direction on both sides of the insulating mounting plate, and the two mounting holes are arranged at intervals along the first direction on the insulating mounting plate.

[0011] Two connecting grooves are provided on the side wall of the insulating housing.

[0012] Optionally, the insulating mounting plate is provided with one of a plug-in groove and a plug-in component, and the insulating protective cover is provided with the other of a plug-in groove and a plug-in component, wherein the plug-in groove and the plug-in component are plugged into each other.

[0013] Optionally, the connector is provided with a first limiting part, and the connector slot is provided with a second limiting part adapted to the first limiting part, and the second limiting part is engaged with the first limiting part.

[0014] Optionally, the mounting position includes a groove for mounting the detector, and the sidewall of the groove is provided with the insertion slot, the insertion slot extending in the same direction as the groove.

[0015] Two connectors are provided on the side wall of the insulating protective cover.

[0016] Optionally, the insulating housing is configured as a square, and the end of the detection electrode is located in the middle of the interior of the insulating housing.

[0017] The number of water passage holes is multiple, and the areas where the multiple water passage holes are arranged correspond to the detection electrodes, and are provided on at least the four sides of the square body.

[0018] Optionally, the insulating housing is provided with a plurality of support feet, which are located at the corners of the bottom of the insulating housing.

[0019] According to a second aspect of this disclosure, a leak detection device is provided, comprising a detection body and a protective casing for the leak detection device described above.

[0020] The detection body includes two locking nuts and two screws.

[0021] The mounting position has two mounting holes, and each mounting hole has a nut mounting groove on the side closest to the inside of the insulating housing. The two locking nuts are installed in the corresponding nut mounting grooves.

[0022] The two screws are configured as two detection electrodes. The two screws are respectively inserted into two mounting holes and connected to the corresponding locking nuts. The two screws are electrically connected to each other.

[0023] The above technical solution involves a protective casing, on which the detection element of the leak detection device is mounted. Its detection electrodes extend into the interior of the insulating casing, which has water passage holes.

Detailed Implementation

[0032] The specific embodiments of this disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0033] In the description of this disclosure, it should be understood that the terms "upper" and "lower," etc., indicate the orientation or positional relationship based on the drawing orientation shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational construction and operation, and therefore should not be construed as a limitation of this disclosure.

[0034] In this disclosure, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Wherein, the first direction is as follows... Figure 1 The direction indicated.

[0035] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0036] The first aspect of this disclosure, such as Figures 1 to 4 As shown, a protective housing 100 for a water leakage detection device is provided, including an insulating housing 10, an insulating mounting plate 20, and an insulating protective cover 30. The insulating housing 10 has an opening 11, and a water passage hole 12 is provided on the side wall of the insulating housing 10. The insulating mounting plate 20 is installed on the insulating housing 10 and covers the opening 11. The insulating mounting plate 20 is provided with a mounting position for installing the detection body of the water leakage detection device, so that the two detection electrodes of the detection body extend into the interior of the insulating housing 10. The insulating protective cover 30 is installed on the outside of the insulating mounting plate 20 and can cover the mounting position.

[0037] The above technical solution involves a protective housing 100, on which the detection element of the leakage detection device is mounted. Its detection electrodes extend into the interior of the insulating housing 10, which has water passage holes 12. This allows water to enter the interior of the insulating housing 10 through the water passage holes 12, thereby conducting electricity to the two detection electrodes and completing the leakage detection. This design protects the detection electrodes, preventing damage and conductivity failure that could lead to the leakage detection device malfunctioning. It also avoids false alarms caused by the detection electrodes touching a conductive material.

[0038] Furthermore, in related technologies, the two bare printed circuit board wires are two-dimensional planes, which are easily covered by dust, causing the detection device to fail. However, in this disclosure, the two detection electrodes are arranged in the three-dimensional space of the insulating housing 10, which can effectively prevent the accumulation of dust.

[0039] In this disclosure, the insulating housing 10, the insulating mounting plate 20, and the insulating protective cover 30 are separately provided, which facilitates the installation of the detection object. That is, the detection object can be installed on the insulating mounting plate 20 first, and then the insulating mounting plate 20 can be installed on the insulating housing 10. In this way, it can be ensured that the installation of the detection object will not be obstructed by the insulating housing 10 or the insulating protective cover 30.

[0040] Here, the opening 11 on the insulating housing 10 provides a mounting position for the insulating mounting plate 20, and also allows the detection electrode to pass through and extend into the interior of the insulating housing 10. The mounting position on the insulating mounting plate 20 provides a mounting position for the detection object, and the mounting position can be a suitable structure such as a slot, snap-fit, or through hole. The insulating protective cover 30 can shield the mounting position, thus protecting the detection object installed there and facilitating insulation and dust prevention.

[0041] In this disclosure, such as Figure 2 As shown, the mounting position may include a groove 21, within which a mounting hole 22 penetrating the insulating mounting plate 20 is provided. The mounting hole 22 is used to mount the detection element. Here, the groove 21 can mount and limit the position of the detection element, facilitating its installation. Furthermore, the mounting hole 22 penetrating the insulating plate allows the detection electrode to pass through and extend into the interior of the insulating housing 10.

[0042] The insulating mounting plate 20 is connected to the insulating housing 10 by means of snap-fit, adhesive, or other suitable methods. In embodiments where the insulating mounting plate 20 and the insulating housing 10 are snap-fitted together, such as... Figure 1 and Figure 2 As shown, the side wall of the insulating mounting plate 20 may be provided with one of a connecting buckle 23 and a connecting groove 13, and the insulating mounting plate 20 is provided with the other of a connecting buckle 23 and a connecting groove 13, with the connecting buckle 23 and the connecting groove 13 fastened together. This facilitates the installation and disassembly of the insulating mounting plate 20 and the insulating housing 10, enabling rapid assembly and disassembly, improving installation efficiency, facilitating adjustment of the position of the detection element and replacement of the detection element, and promoting the repeated use of the protective housing 100.

[0043] In this disclosure, such as Figure 1 and Figure 2 As shown, the insulating mounting plate 20 can be provided with two connecting buckles 23, which are arranged along the first direction on both sides of the insulating mounting plate 20. Two mounting holes 22 are spaced apart on the insulating mounting plate 20 along the first direction, and two corresponding connecting grooves 13 are provided on the side wall of the insulating housing 10. This facilitates the design of the connecting grooves 13 and connecting buckles 23, and placing the connecting grooves 13 on the insulating housing 10 reduces damage to the insulating housing 10. Furthermore, the two connecting buckles 23 are positioned on both sides of the two mounting holes 22, preventing the insulating mounting plate 20 from being obstructed by the detection body installed in the mounting holes 22 when connected to the insulating housing 10.

[0044] The insulating mounting plate 20 and the insulating protective cover 30 are connected by means of snap-fit, adhesive, plug-in, or other suitable methods. In the plug-in configuration between the insulating mounting plate 20 and the insulating protective cover 30, for example... Figure 2 and Figure 4 As shown, the insulating mounting plate 20 is provided with one of a plug-in slot 24 and a plug-in component 31, and the insulating protective cover 30 is provided with the other of the plug-in slot 24 and the plug-in component 31. The plug-in slot 24 and the plug-in component 31 are plugged into each other. The plug-in method is convenient to operate, has a simple process design, is easy to disassemble and replace, and is also convenient to inspect and replace the detection body during maintenance.

[0045] In some embodiments, the insertion slot 24 can be configured as a shrinkage slot with a reduced volume to facilitate clamping of the insertion piece 31.

[0046] To ensure a stable connection between the connector 31 and the slot 24, such as Figure 2 and Figure 4 As shown, the connector 31 may be provided with a first limiting part 311, and the connector slot 24 may be provided with a second limiting part 241 adapted to the first limiting part 311, with the second limiting part 241 engaging with the first limiting part 311. Thus, after the connector 31 is connected to the connector slot 24, the second limiting part 241 and the first limiting part 311 mutually limit each other, preventing relative movement between them and ensuring the stability of the connection between the insulating mounting plate 20 and the insulating protective cover 30.

[0047] For example, the second limiting part 241 and the first limiting part 311 can be a combination of an arc-shaped protrusion and an arc-shaped groove, or a combination of wedge-shaped surfaces. This disclosure does not limit this, as long as it can prevent relative movement between the insertion groove 24 and the insertion member 31.

[0048] Optionally, the mounting position may include a groove 21 for mounting the detection element. A insertion slot 24 may be provided on the side wall of the groove 21, extending in the same direction as the groove 21. Two corresponding insertion pieces 31 are provided on the side wall of the insulating protective cover 30. This prevents interference between the insertion pieces 31 and the detection element mounted on the groove 21 during insertion, facilitating the connection between the insulating mounting plate 20 and the insulating protective cover 30.

[0049] In this disclosure, the insulating housing 10 can be configured as a square, with the end of the detection electrode located in the middle of the interior of the insulating housing 10. This allows water to enter from any direction within the protective housing 100, ensuring that both detection electrodes are energized at approximately the same water level. Multiple water passage holes 12 can be provided, with the areas of these holes corresponding to the detection electrodes and located on at least four sides of the square. This configuration allows accumulated water to flow into the interior of the protective housing 100 in a timely manner, enabling the leakage detection device to detect the water promptly.

[0050] In this context, the four sides of a square refer to the four sides other than the top and bottom surfaces.

[0051] Optionally, the insulating housing 10 may be provided with multiple support feet 14, which are located at the corners of the bottom of the insulating housing 10. This allows the insulating housing 10 to be a certain distance from the ground, preventing the ground drainage holes 12 from being blocked, thus affecting the infiltration and drainage of accumulated water, protecting the insulating housing 10, and allowing the height of the water level to be detected to be adjusted by adjusting the height of the support feet 14.

[0052] Here, the support foot 14 can be configured as a support foot 14 with multiple feet, such as... Figure 1 As shown, the multiple legs of the support feet 14 can extend vertically along the adjacent sides so that the protective shell 100 is supported by the support feet 14 no matter how it is placed on its side.

[0053] According to a second aspect of this disclosure, a leakage detection device is provided, comprising a detection body and a protective shell 100 for the aforementioned leakage detection device. The detection body includes two locking nuts and two screws. Two mounting holes 22 are provided at the mounting position. Each mounting hole 22 has a nut mounting groove 25 on its side near the interior of the insulating shell 10. The two locking nuts are mounted in their corresponding nut mounting grooves 25. The two screws are configured as two detection electrodes, each passing through one of the two mounting holes 22 and connected to its corresponding locking nut. The two screws are electrically connected. This configuration, with the detection body consisting of nuts and screws, facilitates the fixed installation of the detection body on the insulating mounting plate 20, and the threaded connection also facilitates disassembly and replacement. Here, the nut mounting groove 25 can define the position of the locking nuts, facilitating screw tightening. For example, a hexagonal nut can be used as the locking nut, and the nut mounting groove 25 is configured as a hexagonal groove to fit the locking nut, facilitating the limiting of the locking nut's position.

[0054] In this disclosure, such as Figure 3 As shown, a limiting hook 251 is provided on the upper part of the nut mounting groove 25. After the locking nut is installed on the nut mounting groove 25, the limiting hook 251 abuts against the locking nut to prevent the locking nut from loosening and falling off.

[0055] Specifically, an M4 galvanized screw can be used to lock the wiring as a detection electrode by passing through the mounting hole 22 of the groove 21 and engaging with a lock nut. Water passage holes 12 are distributed on all four sides of the insulating housing 10 to allow water to seep in and drain out. The corners of the insulating housing 10 have sixteen-cornered protruding supports, facilitating water seepage and drainage on the ground side of the protective housing 100. When water seeps into the protective housing 100, it conducts electricity to the two galvanized screw detection electrodes, generating a trigger signal.

[0056] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0057] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction, and this disclosure will not describe the various possible combinations separately.

[0058] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
