[0014] The present invention provides a leakage test device for mine low-voltage electrical appliances. It has the following beneficial effects:

[0015] (1) In this invention, when the pulley moves towards the wire, it will push the trapezoidal plate downward. The downward movement of the trapezoidal plate will drive the slider downward. The downward movement of the slider will drive the arc plate downward. The wire is clamped by the downward movement of the arc plate to prevent the wire from sagging downward during the detection, which may affect the detection.

The reciprocating motion of the elastic telescopic plate drives the reciprocating motion of the connecting plate, and the reciprocating motion of the connecting plate drives the reciprocating motion of the arc-shaped brush. The reciprocating motion of the arc-shaped brush is used to clean the dust above the wire, preventing the dust from accumulating on the wire surface, which may cause the leakage monitoring instrument to fail to detect the leakage phenomenon when passing through the leakage area, thus affecting the detection effect. At the same time, the arc-shaped brush shakes up and down to clean the dust adhering to the arc-shaped brush, preventing excessive dust from adhering to the arc-shaped brush and affecting the subsequent cleaning effect of the arc-shaped brush.

Detailed Embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 7 Figures 1 - 7 One embodiment of the present invention is: a leakage test device for mine low-voltage electrical appliances, comprising: a fixed frame 1, a wire 2 penetrates through the inside of the fixed frame 1, an electric slide rail 3 is fixedly installed on the surface of the fixed frame 1, a sliding plate 4 is slidably installed on the surface of the fixed frame 1, a fixed seat 5 is fixedly installed on the surface of the sliding plate 4, a pulley 6 is fixedly installed on the inner wall of the fixed seat 5, a slider 7 is fixedly installed on the surface of the fixed frame 1, an arc plate 71 is fixedly installed at the bottom of the slider 7, a trapezoidal plate 8 is fixedly installed on the surface of the slider 7, an L-shaped plate 9 is fixedly installed on the surface of the sliding plate 4, a limit block 10 is slidably installed on the surface of the fixed frame 1, a sliding block 11 is fixedly installed at the output end of the electric slide rail 3, a connector 12 is fixedly installed on the surface of the sliding block 11, a leakage monitor 13 is fixedly installed at one end of the connector 12 away from the sliding block 11, and an alarm 14 is fixedly installed on the top of the sliding block 11. The wire is clamped by the downward movement of the arc plate 71 to prevent the wire 2 from sagging downward during the detection process, resulting in the wire 2 and the leakage monitor 13 not being at the same height during the detection, which affects the detection result. The surface of the wire 2 is detected by the reciprocating movement of the leakage monitor 13. When a leakage phenomenon is detected in the wire 2, the alarm 14 will give an alarm reminder, and the leakage area can be accurately detected through timely alarm.

[0028] A first spring is provided between the sliding plate 4 and the fixed seat 5 to drive the sliding plate 4 to reset through the first spring. A second spring is provided between the slider 7 and the trapezoidal plate 8 to drive the slider 7 to reset through the second spring. A third spring is provided between the fixed frame 1 and the limit block 10 to drive the limit block 10 to reset through the third spring.

[0029] During the operation of this embodiment: By pushing the L-shaped plate 9 to move towards the wire 2, the sliding plate 4 is driven to move towards the wire 2. When the sliding plate 4 moves towards the wire 2, the fixed seat 5 is driven to move towards the wire 2. When the fixed seat 5 moves towards the wire 2, the pulley 6 is driven to move towards the wire 2. When the pulley 6 moves towards the wire 2, the trapezoidal plate 8 is pushed to move downwards. When the trapezoidal plate 8 moves downwards, the slider 7 is driven to move downwards. When the slider 7 moves downwards, the arc-shaped plate 71 is driven to move downwards. The wire is clamped by the downward movement of the arc-shaped plate 71 to prevent the wire 2 from sagging during the detection process, resulting in the wire 2 and the leakage monitor 13 not being at the same height during detection, which affects the detection result. At the same time, when the L-shaped plate 9 moves towards the wire 2, the limit block 10 is pushed to move away from the L-shaped plate 9. When the L-shaped plate 9 is separated from the limit block 10, the limit block 10 will reset under the elastic force of the third spring. The L-shaped plate 9 is limited by the reset of the limit block 10 to ensure that the arc-shaped plate 71 can clamp the wire 2. At the same time, the slider 11 is driven to reciprocate by the electric slide rail 3. The reciprocating movement of the slider 11 drives the connector 12 to reciprocate. The reciprocating movement of the connector 12 drives the leakage monitor 13 to reciprocate. The surface of the wire 2 is detected by the reciprocating movement of the leakage monitor 13. When it is detected that there is a leakage phenomenon in the wire 2, the alarm 14 will give an alarm reminder. The leakage area can be accurately detected through timely alarm.

The wire 2 is supported by the reciprocating movement of the guide wheel 154 to prevent the wire 2 from sagging due to its own weight, which affects the accuracy of the detection.

[0031] An electric telescopic device 155 is installed on the surface of the fixed plate 151. A long plate 156 is fixedly installed at the bottom of the electric slide rail 3. A short plate 157 is fixedly installed on the surface of the long plate 156. When detecting the leakage area, the electric slide rail 3 continues to slide, resulting in an inaccurate detected leakage area and affecting the detection effect.

[0033] The dust removal device includes an elastic telescopic plate 161, a connecting plate 162 and an arc brush 163. The elastic telescopic plate 161 is fixedly installed on the top of the square plate 153. The connecting plate 162 is fixedly installed at the free end of the elastic telescopic plate 161. The arc brush 163 is fixedly installed at the bottom of the connecting plate 162 to prevent dust from accumulating on the surface of the wire 2, resulting in the leakage monitoring instrument 13 failing to detect the leakage phenomenon when passing through the leakage area, affecting the detection effect.

A roller 166 is rotatably installed on the surface of the semi-circular block 165. A convex block 167 is fixedly installed on the top of the electric slide rail 3. The dust adhered to the arc brush 163 is cleaned off by the up and down shaking of the arc brush 163 to prevent too much dust from adhering to the arc brush 163 and affecting the subsequent cleaning effect of the arc brush 163.

[0035] The arc brush 163 is in contact with the surface of the wire 2, and the surface of the wire 2 is cleaned by the arc brush 163. The roller 166 is in contact with the surface of the convex block 167.

[0036] When this embodiment works: the reciprocating movement of the sliding block 11 drives the reciprocating movement of the fixed plate 151. The reciprocating movement of the fixed plate 151 drives the reciprocating movement of the L-shaped rod 152. The reciprocating movement of the L-shaped rod 152 drives the reciprocating movement of the square plate 153. The reciprocating movement of the square plate 153 drives the reciprocating movement of the guide wheel 154. The wire 2 is supported by the reciprocating movement of the guide wheel 154 to prevent the wire 2 from sagging downward due to its own weight, affecting the accuracy of detection. At the same time, when a leakage area is detected, the alarm 14 will trigger the electric telescopic device 155, and the output end of the electric telescopic device 155 will move in the direction close to the long plate 156. The electric telescopic device 155 is clamped between the short plates 157 to limit the sliding block 11, preventing the electric slide rail 3 from continuously sliding when a leakage area is detected due to the inertia of the reciprocating movement of the electric slide rail 3, resulting in an inaccurate detected leakage area and affecting the detection effect.

[0037] The reciprocating motion of the square plate 153 drives the reciprocating motion of the elastic telescopic plate 161. The reciprocating motion of the elastic telescopic plate 161 drives the reciprocating motion of the connecting plate 162. The reciprocating motion of the connecting plate 162 drives the reciprocating motion of the arc-shaped brush 163. The reciprocating motion of the arc-shaped brush 163 is used to clean the dust above the wire 2, preventing the dust from accumulating on the surface of the wire 2, which may cause the leakage monitoring instrument 13 to fail to detect the leakage phenomenon when passing through the leakage area, affecting the detection effect. At the same time, the reciprocating motion of the connecting plate 162 drives the reciprocating motion of the connecting rod 164. The reciprocating motion of the connecting rod 164 drives the reciprocating motion of the semi-circular block 165. The reciprocating motion of the semi-circular block 165 drives the reciprocating motion of the roller 166. The reciprocating motion of the roller 166 contacts the convex block 167, and the convex block 167 pushes the roller 166 to move upward. The upward movement of the roller 166 drives the connecting rod 164 and the connecting plate 162 to move upward. The upward movement of the connecting plate 162 drives the arc-shaped brush 163 to move upward. The dust adhering to the arc-shaped brush 163 is cleaned off by the up-and-down shaking of the arc-shaped brush 163, preventing excessive dust from adhering to the arc-shaped brush 163 and affecting the subsequent cleaning effect of the arc-shaped brush 163.
