DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] like Figure 1 As shown, the present invention provides a distribution room detection and maintenance device, including an operating handle 1, a steering base 2, an operating connecting rod 3, a flexible component 4 and an actuator connected in sequence from the proximal end to the distal end, wherein the steering base 2 is provided with a transmission component for driving the flexible component 4 to rotate in a universal direction, as shown in FIG. Figure 2 As shown, the actuator includes a hot melt glue gun 6, a clamp assembly 5 installed on the hot melt glue gun 6 and arranged side by side with the gun head of the hot melt glue gun 6, and a camera assembly 7. A display control unit 701 electrically connected to the camera assembly 7 is installed on the operating handle 1. The operating handle 1 has a first switch component and a second switch component. The front ends of the first switch component and the second switch component are respectively connected to a first steel wire flexible shaft and a second steel wire flexible shaft. The first steel wire flexible shaft and the second steel wire flexible shaft successively penetrate the steering base 2, the operating connecting rod 3 and the flexible component 4 axially and then penetrate into the hot melt glue gun 6. The front end of the first steel wire flexible shaft is connected to the gluing component of the hot melt glue gun 6 to drive the hot melt glue gun 6 to glue. The front end of the second steel wire flexible shaft is connected to the clamp assembly 5 to drive the clamp assembly 5 to open and close. It is further preferred that in order to avoid interference between the first steel wire flexible shaft and the second steel wire flexible shaft when they are in motion, the first steel wire flexible shaft and the second steel wire flexible shaft have independent penetration paths in the flexible component 4, the operating connecting rod 3 and the steering base 2 respectively.

[0018] like Figure 3 and Figure 4As shown, the steering base 2 includes a support sleeve 201, a universal ball 202 and a locking screw 203. The front end of the support sleeve 201 is connected to the operating connecting rod 3, and the rear end of the support sleeve 201 has an inner spherical surface that rotates with the universal ball 202. The rear end of the universal ball 202 has a connecting portion 2021 for connecting to the operating handle 1. Specifically, there is a connection between the support sleeve 201 and the operating connecting rod 3, and between the universal ball 202 and the operating handle 1. Fixed connection, preferably adhesive fixation can be used, the inner spherical surface of the universal ball 202 and the support sleeve 201 cooperate to form a ball-jointed hinge structure, the locking screw 203 threadedly penetrates the support sleeve 201 and is in locking contact with the universal ball 202, the transmission assembly includes four deflection steel wires arranged circumferentially in the support sleeve 201 and the operating connecting rod 3, the rear end of the deflection steel rope is fixedly connected to the universal ball 202, and the front end of the deflection steel rope is fixedly set after passing through the flexible assembly 4. When operating the device, hold the support sleeve 201 and rotate the operating handle 1. The universal sphere 202 rotates in the support sleeve 201 according to the direction of the operating handle 1, and pulls the four deflection wires fixed inside it. The deflection wire drives the flexible component 4 to rotate in the opposite direction of the rotation of the operating handle 1, and then the actuator connected to the front end of the flexible component 4 also rotates together, and the transmission component in the steering base 2 drives the actuator to rotate. Since the hot melt glue gun 6, the clamp assembly 5 and the camera assembly 7 are integrated in the actuator, the distribution box can be fully explored through the camera assembly 7 without pushing out the entire distribution cabinet. Specifically, the camera assembly 7 uses an endoscopic camera with a built-in LED to assist in imaging. After the cable is found to be damaged, the second switch component is driven to clamp the cable that needs to be repaired, and then the first switch component is driven to glue and repair the clamped cable. The whole operation process is convenient and fast, can adapt to narrow maintenance space, reduce the workload of maintenance personnel, and ensure maintenance efficiency.

[0019] like Figure 2 and Figure 8 As shown, the flexible component 4 includes a flexible joint part 401 and a connecting seat 402, and the two ends of the flexible joint part 401 are fixedly connected to the operating connecting rod 3 and the connecting seat 402. The middle part of the flexible joint part 401 and the connecting seat 402 is provided with a through hole for the first steel wire flexible shaft and the second steel wire flexible shaft to pass through. Each joint of the flexible joint part 401 is circumferentially provided with four through holes for the deflection steel rope to pass through. Specifically, the front end and the rear end of the deflection steel rope are connected with a wire knot, the wire knot at the front end is located on the end face of the front end joint of the flexible joint part 401, and the wire knot at the rear end is located on the rear end face of the universal sphere 202. The front end of the connecting seat 402 is fixedly connected to the outer side of the hot melt glue gun 6 through two brackets arranged side by side, and a guide pulley 4021 for winding the first steel wire flexible shaft and the second steel wire flexible shaft is provided between the two brackets.

[0020] like Figure 2 As shown, the gluing assembly includes a limiting sleeve 602, a movable plate 603 and a gluing pulley 9. The limiting sleeve 602 is slidably installed on the front side of the glue inlet of the hot melt glue gun 6 along the gluing path of the glue stick 601, and the movable plate 603 is rotatably installed on the rear end of the limiting sleeve 602. The upper end surface of the movable plate 603 has a meshing portion for clamping the glue stick 601 during the gluing process. The above structure is the same as the existing structure of the hot melt glue gun 6, which is not repeated here. It is worth mentioning that the gluing pulley 9 is installed on the inner wall of the hot melt glue gun 6 below the front end of the limiting sleeve 602 via a transverse rotating shaft. After the front end of the first steel wire flexible shaft penetrates into the hot melt glue gun 6, it bypasses the gluing pulley 9 and is fixedly connected to the lower end of the movable plate 603. A hanging hole is provided on the side of the movable plate 603 away from the gluing pulley 9, and the hanging hole is connected to the inner wall of the hot melt glue gun 6 via an elastic hook 604.

[0021] like Figure 4 The first switch member matched with the gluing assembly includes a trigger handle 102 and a tension spring 104. The trigger handle 102 is inserted into the operating handle 1 and is rotatably connected to the operating handle 1. The upper end of the trigger handle 102 has a connection hole connected to the first steel wire flexible shaft. The operating handle 1 is provided with a connecting column 103. The two ends of the tension spring 104 are respectively connected to the connecting column 103 and the upper end of the movable handle. When the trigger wrench is pulled, the upper end of the trigger handle 102 pulls the first steel wire flexible shaft backward, and the first steel wire flexible shaft drives the moving plate 603 and the limit sleeve 602 forward after bypassing the gluing pulley 9, completing the gluing operation.

[0022] like Figure 5-Figure 7 As shown, the clamp assembly 5 includes an articulated seat 503, a clamp body 1 501, a clamp body 2 502 and a driving block 8. The articulated seat 503 is installed on the hot melt glue gun 6 and an axial through hole 5031 communicating with the inner side of the hot melt glue gun 6 is opened in the middle of the articulated seat 503. The middle parts of the clamp body 1 501 and the clamp body 2 502 are hinged in the articulated seat 503 via a hinge shaft, and the surfaces of the clamp body 1 501 and the clamp body 2 502 located in the articulated seat 503 are opened with an inclined sliding hole 5011. Sliding shafts 801 that slide with the sliding hole 5011 are formed at both ends of the driving block 8, and a driving rod 802 that penetrates into the axial through hole 5031 is formed at the bottom of the driving block 8. A compression spring 803 is sleeved on the outer side of the driving rod 802, and the two ends of the compression spring 803 are respectively abutted against the driving block 8 and the hinge seat 503. A steering pulley block 10 is installed in the hot melt glue gun 6. After the front end of the second steel wire flexible shaft penetrates into the hot melt glue gun 6, it bypasses the steering pulley block 10 and penetrates into the hinge seat 503 and is fixedly connected to the driving rod 802.

[0023] like Figure 4The second switch member matched with the clamp assembly 5 includes a pull rod 105 and a sliding seat 101 fixed at the rear end of the operating handle 1. The pull rod 105 passes through the sliding seat 101 and is connected to the second steel wire flexible shaft. The sliding seat 101 extends with a positioning frame 1011 in the direction away from the operating handle 1. The outer side of the pull rod 105 has a limit plate 1051 abutting against the outer end surface of the sliding seat 101. The size of the limit plate 1051 is smaller than the inner length of the positioning frame 1011 and larger than the outer width of the positioning frame 1011. In the initial state, the driving block 8 is located below the hinge axis of the clamp body 1 501 and the clamp body 2 502 under the elastic force of the compression spring 803. At this time, the sliding shaft 801 of the driving block 8 is located at the front end of each sliding hole 5011, and the clamp body 1 501 and the clamp body 2 502 are in an open state. In this state, they are docked on the outside of the cable to be repaired, and the pull rod 105 is pulled until the limit plate 1051 reaches the outside of the positioning frame 1011. At this time, the pull rod 105 is rotated. Since the size of the limit plate 1051 is larger than the width of the positioning frame 1011, the limit plate 1051 limits the pull rod 105 at this position, and the front end of the second steel wire flexible shaft drives the driving block 8 to move backward under the pulling of the pull rod 105, and the sliding shaft 801 slides along the sliding hole 5011 to drive the two clamp bodies to close, thereby completing the clamping action of the cable.

[0024] In order to facilitate the glue filling process, the gun head of the hot melt glue gun 6 can move within a certain range, thereby ensuring its glue filling area, as shown in FIG. Figure 5-Figure 7 As shown, a deflection seat 504 is fixed at the connection between the hot melt glue gun 6 and the hinge seat 503, and a coaxial hole 5041 corresponding to the axial through hole 5031 is provided in the middle of the deflection seat 504, and the front end of the deflection seat 504 and the rear end of the hinge seat 503 are provided with an ear seat part 12 hinged to each other, and springs 11 are provided on both sides of the coaxial hole 5041, and the two ends are respectively connected to the deflection seat 504 and the hinge seat 503. Specifically, the hinge axis between the clamp bodies and the hinge axis between the ear seat parts 12 are vertically arranged, and the clamp assembly 5 moves around the hinge center of the ear seat part 12 to move closer to or away from the gun head direction of the hot melt glue gun 6.

[0025] When the construction personnel inspect and repair the power distribution room, they use the above-mentioned power distribution room detection and maintenance device. The operation steps are as follows: S1. Extend the operating connecting rod 3 into the distribution box, hold the supporting sleeve 201, rotate the operating handle 1 to drive the universal ball 202 to rotate, and then drive the flexible component 4 and the actuator connected to it to rotate in the opposite direction, and use the display control unit 701 to view the video information collected from the camera component 7 of the actuator; S2. If the insulation layer of the cable is damaged, tighten the locking screw 203 on the outside of the support sleeve 201 to lock the bending angle of the flexible component 4, and the clamp component 5 is in the open state to abut against the corresponding cable, and drive the second switch on the operating handle 1 to stably clamp the clamp component 5 on the outside of the cable; S3, turning on the hot melt glue gun 6, and driving the first switch on the operating handle 1 to apply glue to the gun head of the hot melt glue gun 6, and filling the damaged part of the cable with insulating glue according to the video information collected by the camera assembly 7; S4. Restore the device to its initial state and inspect other locations of the distribution box. If other cable insulation layers are found to be damaged, repeat S2-S3.

[0026] This device can complete a comprehensive exploration of the distribution box without pushing out the entire distribution cabinet, and complete the gluing and repairing operation of the cable with the cooperation of the first switch component and the second switch component. It can adapt to narrow maintenance space, reduce the workload of maintenance personnel, and ensure maintenance efficiency.
