Technical Field

[0001] The utility model relates to the technical field of water immersion detectors, in particular to a water immersion detector. Background Art

[0002] A water immersion detector is a sensor for detecting whether water leakage occurs in a measured range. Once water leakage occurs, an alarm is immediately issued to prevent relevant losses and hazards caused by the water leakage accident. Water immersion sensors are widely used in all waterproof places such as data centers, communication machine rooms, power stations, warehouses, and archives. In some places, after water leakage occurs, a small amount of seepage and ponding will not cause serious impacts on equipment, materials, etc., but if the ponding is excessive, major problems will occur, such as air conditioning machine rooms, elevator shafts, etc. Existing water immersion detectors are usually fixedly installed, and in order to detect water leakage in the first time, the probe of the water immersion detector is usually fixedly installed after contacting the ground. This results in a single function of the existing water immersion detector and cannot detect the severity of the water leakage danger, so a water immersion detector is proposed.

Specific embodiments

[0022] In order to make the invention purpose, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present simultaneously.

[0024] The technical solution of the present utility model will be further described below with reference to the drawings and through specific embodiments.

[0025] Refer to Figures 1 to 4 , an embodiment of the present utility model provides a water immersion detector, which includes a main body 10 and an adjustment mechanism 20. The main body 10 is in the shape of a cuboid, and a detection member 11 is provided on the bottom surface of the main body 10 for detecting whether there is water leakage on the ground to be detected. A water level switch 12 is provided on the side surface of the main body 10, and there is a height difference between the detection member 11 and the water level switch 12. When the water level switch 12 comes into contact with water, the water level switch 12 turns on the circuit; when the water level switch 12 is not in contact with water, the water level switch 12 turns off the circuit.

[0026] The adjustment mechanism 20 includes a driving motor 21, a threaded rod 22, a slider 23 and an encoder guide post 24. The threaded rod 22 is provided on the output shaft of the driving motor 21, and the axis of the threaded rod 22 is on the same straight line as the axis of the output shaft of the driving motor 21, so that the threaded rod 22 rotates synchronously with the output shaft of the driving motor 21. The slider 23 is provided with an internal threaded hole (not shown in the figure) corresponding to the threaded rod 22, and the threaded rod 22 passes through the internal threaded hole. When the threaded rod 22 rotates, the slider 23 can slide on the threaded rod 22. The main body 10 is connected to the slider 23 through a connecting rod 30. Specifically, two first connecting rods extend from both sides of the main body 10, and second connecting rods perpendicular to the first connecting rods are provided on both sides of the slider 23, and the first connecting rods and the second connecting rods are fixedly connected. The water level switch 12 is electrically connected to the driving motor 21. When the water level switch 12 turns on the circuit, the driving motor 21 drives the threaded rod 22 to rotate, thereby driving the main body 10 to rise; when the water level switch 12 turns off the circuit, the driving motor 21 stops working. An encoder is provided on the output shaft of the driving motor 21, and this encoder is used to detect the number of turns of rotation of the driving motor 21, so as to obtain the rising distance of the main body 10.

[0027] Through the above technical solution, when the water immersion detector of the present utility model is used to detect environments such as air conditioning machine rooms and elevator shafts, by fitting the bottom surface of the main body 10 to the ground to be detected, even if the detection member 11 contacts the bottom surface, real-time detection of the ground to be detected can be achieved; when the ground to be detected leaks water, it can be detected by the detection member 11; when water accumulates due to leakage of the ground to be detected and the accumulated water contacts the water level switch 12, the driving motor 21 is started to work through the water level switch 12. The driving motor 21 drives the threaded rod 22 to rotate, and the threaded rod 22 drives the slider 23 to rise, thereby driving the main body 10 to rise, that is, the water level is always between the detection member 11 and the water level switch 12. At the same time, the number of turns of rotation of the driving motor 21 is obtained through the encoder, so as to obtain the rising height of the main body 10 to judge the depth of the accumulated water, and finally obtain the severity of the water leakage danger, solving the technical problem that the existing water immersion detector can only detect whether the ground to be detected leaks water and cannot detect the severity of the water leakage danger.

[0028] Further, the detection member 11 includes a first conductive sheet 111 and a second conductive sheet 112 that do not contact each other, and a first sensor (not shown in the figure) is provided in the main body 10. The first conductive sheet 111 is electrically connected to the positive electrode of the first sensor through a wire, and the second conductive sheet 112 is electrically connected to the negative electrode of the first sensor through a wire. It should be noted that the material of the main body 10 is an insulating material. The bottom surface of the main body 10 is fitted to the ground to be detected, and when there is water on the bottom surface of the main body 10, the first conductive sheet 111 and the second conductive sheet 112 are electrically connected through the water, thereby realizing the conduction of the first sensor. It should be further noted that a power supply is provided in the circuit. When the first conductive sheet 111 and the second conductive sheet 112 are electrically connected through the water, the first sensor is powered on, thereby realizing water leakage detection.

[0029] To avoid damaging the first conductive sheet 111 and the second conductive sheet 112 due to the extrusion of the bottom surface of the main body 10 on the first conductive sheet 111 and the second conductive sheet 112 when the bottom surface of the main body 10 is in contact with the ground to be detected. In this embodiment, a first installation groove 13 and a second installation groove 14 are provided on the bottom surface of the main body 10. The first conductive sheet 111 is disposed in the first installation groove 13, and the second conductive sheet 112 is disposed in the second installation groove 14. To avoid the first conductive sheet 111 and the second conductive sheet 112 not contacting the ground to be detected due to the excessive depth of the first installation groove 13 and the second installation groove 14 when the bottom surface of the main body 10 is in contact with the ground to be detected. In this embodiment, elastic sheets 16 are provided in both the first installation groove 13 and the second installation groove 14, and the first conductive sheet 111 is disposed on one side of the elastic sheet 16 away from the bottom wall surface of the first installation groove 13, and the second conductive sheet 112 is disposed on one side of the elastic sheet 16 away from the bottom wall surface of the second installation groove 14. When the bottom surface of the main body 10 is not in contact with the ground to be detected, the first conductive sheet 111 and the second conductive sheet 112 protrude slightly from the bottom surface of the main body 10 under the elastic force of the elastic sheet 16; when the bottom surface of the main body 10 is in contact with the ground to be detected, the first conductive sheet 111 and the second conductive sheet 112 are subjected to the force of the ground, so that the elastic sheet 16 is compressed under pressure, that is, the elastic force of the elastic sheet 16 makes the first conductive sheet 111 and the second conductive sheet 112 always in contact with the ground. To facilitate the installation of the elastic sheet 16, inner grooves are provided on two opposite side walls of the first installation groove 13 and the second installation groove 14. When installing the elastic sheet 16, both ends of the elastic sheet 16 can be inserted into the inner grooves.

[0030] When the bottom surface of the main body 10 is in contact with the ground to be detected, to avoid the main body 10 from obstructing the water flow to the first conductive sheet 111 and the second conductive sheet 112, in this embodiment, a water guide groove 15 is further provided on the bottom surface of the main body 10. The water guide groove 15 communicates with the first installation groove 13 and the second installation groove 14, and the water guide groove 15 extends to the side surface of the main body 10.

[0031] Further, the adjusting mechanism 20 further includes a guide post 24. The guide post 24 is provided with a guide groove 25 in the vertical direction, and the slider 23 can slide in the guide groove 25. The threaded rod 22 passes through the guide groove 25 and is rotatably connected to the guide post 24. The driving motor 21 is disposed on the upper end surface of the guide post 24, and the output shaft of the driving motor 21 passes through one end of the guide post 24 and is connected to the threaded rod 22.

[0032] Furthermore, a mounting plate 40 is provided on the side of the guide post 24 away from the main body 10, and a mounting hole 41 is provided on the mounting plate 40. When the water immersion detector of the present utility model is used to detect environments such as air-conditioning machine rooms and elevator shafts, it is installed on the side walls of the air-conditioning machine room and elevator shaft through the mounting plate 40, and then the driving motor 21 is rotated in the reverse direction to make the bottom surface of the main body 10 fit the ground to be detected. It should be noted that the driving motor 21 in this embodiment is a bidirectional motor, that is, it can rotate forward and reverse. When the driving motor 21 rotates forward, it drives the main body 10 to rise; when the driving motor 21 rotates in the reverse direction, it drives the main body 10 to descend.

[0033] As described above, the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than limiting it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
