Description

Technical Field

[0001] The utility model relates to the technical field of water immersion sensors, in particular to a water immersion sensor with a protection mechanism. Background Art

[0002] A water immersion sensor is a sensor that detects whether water leakage occurs in the measured range. Once water leakage occurs, an alarm is immediately issued to prevent relevant losses and hazards caused by the water leakage accident. In the electrical room, since there is a long wire connecting the sensor body and the detection head, the wire is easily bitten off by mice; the detection head is generally arranged at a position close to the ground. Due to the low position of the detection head, it is easy to be ignored and hit the detection head when handling equipment, thereby damaging the detection head.

[0003] Based on the above problems, the utility model proposes a water immersion sensor with a protection mechanism. Summary of the Utility Model

Specific embodiments

[0021] The present utility model will be further described below:

[0022] Please refer to Figure 1-5 ,

[0023] The present utility model discloses a water immersion sensor with a protection mechanism, including a sensor body 1, a wire 2, a detection head 3, a back plate 4, side plates 5, a bottom plate 6 and a front plate 7. The sensor body 1 is fixed to the top of the front wall of the back plate 4 in a square structure. The top end of the wire 2 is connected to the inside of the sensor body 1, and the bottom end of the wire 2 is connected to the inside of the detection head 3. The back plate 4 is fixed to the wall surface, and the two sides of the front wall of the back plate 4 are connected to the rear ends of the two side plates 5 to form a "C"-shaped structure. The bottom plate 6 is connected to the bottom ends of the two side plates 5, and a plurality of first water permeable holes 9 are arranged in a rectangular array on the bottom plate 6. A sliding groove 8 for the front plate 7 to slide is provided on the inner wall of the front end of the side plate 5, and the rear wall of the sliding groove 8 is flush with the front wall of the sensor body 1. A hollow square box body is formed by the rear wall of the front plate 7, the bottom of the sensor body 1, the inner wall of the side plate 5 and the top of the bottom plate 6. The wire 2 and the detection head 3 are located in the inner cavity of the square box body. The hollow square box body formed by the rear wall of the front plate 7, the bottom of the sensor body 1, the inner wall of the side plate 5 and the top of the bottom plate 6 can protect the wire 2 and the detection head 3, prevent the wire 2 from being bitten by mice or damaged by hitting the detection head 3 when handling equipment, and ensure that the water immersion sensor can normally detect whether there is water leakage in the electrical room. By providing the first water permeable holes 9 on the bottom plate 6, when there is water leakage in the electrical room, water can enter the square box body through the first water permeable holes 9, so that the detection head 3 can normally detect.

[0024] Furthermore, the front plate 7 is made of transparent material, which is convenient for observing whether the wires 2 and the detection head 3 in the square box are damaged. The front plate has a plurality of second water-permeable holes 10 in a rectangular array as spare water-permeable holes to prevent the first water-permeable holes 9 on the bottom plate 6 from being blocked by debris when the water rises, resulting in the rising water being unable to enter the square box through the first water-permeable holes 9, thereby affecting the detection of water leakage by the detection head 3; when the front plate 7 is inserted into the slide groove 8, the top end of the front plate 7 is flush with the bottom end of the sensor body 1.

[0025] Furthermore, a clamping member 11 for clamping the detection head 3 is provided below the inner wall of the side panel 5, and the clamping member 11 includes a clamping head 111 and a clamping rod 112. The clamping heads 111 on both sides are in an arc-shaped structure, and their inner walls form clamping grooves 113 for inserting the detection head 3 on both sides. The middle parts of the outer walls of the clamping heads 111 on both sides are connected to the inner ends of the clamping rods 112, and the outer ends of the clamping rods 112 are fixed to the side panel 5 through the telescopic mechanism 12.

[0026] Furthermore, the telescopic mechanism 12 includes a base 121, a telescopic slot 122, a compression spring 123, a lever slot 124 and a lever 125. The base 121 is a square structure fixed to the lower side of the outer wall of the side plate 5. The inner end surface of the base 121 is provided with the telescopic slot 122. The side plate 5 is provided with a square hole 126 with the same cross-sectional shape as the telescopic slot 122. The outer end of the clamping rod 112 passes through the square hole 126 and slides with the telescopic slot 122. The compression spring 123 is connected between the inner end wall of the telescopic slot 122 and the outer end of the clamping rod 112. The top of the base 121 is provided with a lever slot 124 connected to the telescopic slot 122. The lever 125 passes through the lever slot 124 and slides with the clamping rod The top of the outer end of the holding rod 112 is connected. When the detection head 3 needs to be clamped by the clamping member 11, the user pushes the lever 125 of the telescopic mechanism 12 on one side outward, driving the clamping rod 112 to move outward along the telescopic slot 122, driving the clamping head 111 of the detection head to move outward, so that the distance between the two clamping heads 111 becomes larger, and then the other side of the detection head 3 is inserted into the clamping slot 113 of the clamping head 111 on the other side, and then the lever 125 is released. Due to the reset effect of the compression spring 123, the clamping rod 112 moves inward along the telescopic slot 122 until the detection head 3 is clamped, thereby completing the clamping and fixing of the detection head 3, ensuring that the detection head 3 will not be displaced in the vertical direction due to external factors, etc., which affects the detection accuracy of the water immersion sensor.

[0027] Furthermore, the spacing between the side panels 5 on both sides is equal to the width of the sensor body 1, ensuring that there is no gap between the side panels 5 and the sensor body 1 to prevent mice and the like from getting into the square box.

[0028] Furthermore, both sides of the back plate 4 are provided with connecting plates 13 integrally formed therewith, and a plurality of bolt holes 14 are provided on the connecting plates 13 at intervals along the vertical direction, so as to facilitate the entire protection mechanism to be fixedly installed on the wall of the power room by bolts.

[0029] Furthermore, a first contact 31 and a second contact 32 are provided on both sides of the front wall of the detection head 3; the wire 2 includes a first wire 21 and a second wire 22, the first contact 31 is connected in series with the power supply 101 and the alarm 102 in the sensor body 1 through the first wire 21, and the second contact 32 is connected in series with the power supply 101 and the alarm 102 in the sensor body 1 through the second wire 22, the first contact 31, the first wire 21, the power supply 101, the alarm 102, the second wire 22 and the second contact 32 form a series circuit, when the water in the power room does not cover the first contact 31 and the second contact 32, the circuit is in an open state; when the water in the power room covers the first contact 31 and the second contact 32, the first contact 31 and the second contact 32 are connected through water conduction, so that the circuit is closed and the alarm 102 is triggered to alarm.
