Description

Technical Field

[0001] This invention relates to the field of power supply maintenance technology, and in particular to a power distribution room inspection and maintenance device and its usage method. Background Technology

[0002] During power distribution maintenance, it is necessary to conduct hazard inspections on the cables in the power distribution room. Among these, damage to the cable insulation caused by aging or rodent infestation is particularly prominent, and cable repair is a key focus of the maintenance work. Since the distribution boxes used in the power distribution room are usually assembled in a cabinet-like plug-in configuration, when inspecting the cables in the distribution box, the entire distribution box needs to be pushed out of the cabinet for inspection. When cable insulation damage is found, it needs to be repaired and maintained with insulating glue in the narrow maintenance passage. The entire process involves a large amount of moving work, limited maintenance space, and consumes the physical strength of maintenance personnel, affecting maintenance efficiency. Furthermore, when high-level distribution boxes are involved, it is necessary to work at height, which increases the difficulty and danger of the operation. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention provides a power distribution room inspection and maintenance device and its usage method, which assists maintenance personnel in inspection and maintenance work and improves maintenance efficiency.

[0004] The technical solution of the present invention is as follows: a power distribution room inspection and maintenance device, comprising an operating handle, a steering base, an operating connecting rod, a flexible component, and an execution mechanism connected sequentially from the near end to the far end. The steering base is provided with a transmission component for driving the flexible component to rotate in all directions. The execution mechanism includes a hot melt glue gun, a clamping component mounted on the hot melt glue gun and arranged parallel to the head of the hot melt glue gun, and a camera component. The operating handle is equipped with a display control unit electrically connected to the camera component. The operating handle has a first switch and a second switch. The front ends of the first switch and the second switch are respectively connected to a first flexible steel wire shaft and a second flexible steel wire shaft. The first flexible steel wire shaft and the second flexible steel wire shaft pass through the steering base, the operating connecting rod, and the flexible component in sequence along the axial direction and then pass into the hot melt glue gun. The front end of the first flexible steel wire shaft is connected to the glue application component of the hot melt glue gun to drive the hot melt glue gun to apply glue, and the front end of the second flexible steel wire shaft is connected to the clamping component to drive the clamping component to open and close. The actuator integrates a hot melt glue gun, clamp assembly, and camera assembly. The actuator is driven to rotate by the transmission assembly in the steering base, allowing for a comprehensive inspection of the distribution box without removing the entire distribution cabinet. The actuator then sequentially activates the second and first switches to clamp the cables requiring repair before applying glue. The operation is convenient, adaptable to narrow maintenance spaces, and ensures maintenance efficiency.

[0005] The steering base includes a support sleeve, a universal ball, and a locking screw. The front end of the support sleeve is connected to the operating connecting rod. The rear end of the support sleeve has an inner spherical surface that rotatably engages with the universal ball. The rear end of the universal ball has a connecting part for connecting with the operating handle. The locking screw is threaded through the support sleeve and locks into contact with the universal ball. The transmission assembly includes four deflection steel cables arranged circumferentially in the support sleeve and the operating connecting rod. The rear end of the deflection steel cables is fixedly connected to the universal ball, and the front end of the deflection steel cables passes through the flexible assembly and is fixedly installed.

[0006] The glue application assembly includes a limiting sleeve, a movable plate, and a glue application pulley. The limiting sleeve is slidably installed on the front side of the glue inlet of the hot melt glue gun along the glue stick application path. The movable plate is rotatably installed on the rear end of the limiting sleeve. The glue application pulley is installed on the inner wall of the hot melt glue gun below the front end of the limiting sleeve via a transverse rotating shaft. After the front end of the first steel wire flexible shaft passes through the hot melt glue gun, it passes around the glue application pulley and is fixedly connected to the lower end of the movable plate. The movable plate has a hanging hole on the side away from the glue application pulley, and the hanging hole is connected to the inner wall of the hot melt glue gun via an elastic hook.

[0007] The clamp assembly includes a hinge base, clamp body one, clamp body two, and a drive block. The hinge base is mounted on the hot melt glue gun, and an axial through hole communicating with the inner side of the hot melt glue gun is opened in the middle of the hinge base. The middle parts of clamp body one and clamp body two are hinged to the hinge base via hinge shafts, and inclined sliding holes are opened on the surfaces of clamp body one and clamp body two located in the hinge base. The drive block has sliding shafts formed at both ends that cooperate with the sliding holes to slide. A drive rod is formed at the bottom of the drive block that passes through the axial through hole. A compression spring is sleeved on the outside of the drive rod, with its two ends respectively abutting against the drive block and the hinge base. A steering pulley assembly is installed inside the hot melt glue gun. After the front end of the second steel wire flexible shaft passes through the hot melt glue gun, it passes around the steering pulley assembly and passes into the hinge base and is fixedly connected to the drive rod.

[0008] The first switching element includes a trigger handle and a tension spring. The trigger handle is inserted into the operating handle and rotatably connected to the operating handle. The upper end of the trigger handle has a connecting hole that is connected to the first steel wire flexible shaft. The operating handle is provided with a connecting post. The two ends of the tension spring are respectively connected to the connecting post and the upper end of the trigger handle.

[0009] The second switch includes a pull rod and a sliding seat fixed to the rear end of the operating handle. The pull rod passes through the sliding seat and is connected to the second steel wire flexible shaft. The sliding seat has a positioning frame extending in a direction away from the operating handle. The pull rod has a limiting plate on its outer side that abuts against the outer end face of the sliding seat. The size of the limiting plate is smaller than the inner length of the positioning frame and larger than the outer width of the positioning frame.

[0010] The flexible component includes a flexible joint and a connecting seat. The two ends of the flexible joint are fixedly connected to the operating connecting rod and the connecting seat. The flexible joint and the connecting seat have through holes in the middle for the first and second flexible steel wire shafts to pass through. Each joint of the flexible joint has four through holes along the circumference for the deflection steel rope to pass through. The front end of the connecting seat is fixedly connected to the outside of the hot melt glue gun via two brackets arranged side by side. A guide pulley for winding around the first and second flexible steel wire shafts is provided between the two brackets.

[0011] A deflector is fixed at the connection between the hot melt glue gun and the hinge seat. The deflector has a coaxial hole in the middle that corresponds to and communicates with the axial through hole. The front end of the deflector and the rear end of the hinge seat have ear seats that are hinged to each other. Springs with their two ends connected to the deflector and the hinge seat are provided on both sides of the coaxial hole. The clamp assembly moves toward or away from the head of the hot melt glue gun around the hinge center of the ear seat.

[0013] S1. Insert the operating connecting rod into the distribution box, hold the support sleeve, and rotate the operating handle to drive the universal ball to rotate, thereby driving the flexible component and its connected actuator to rotate in the opposite direction. The display control unit can then view the video information collected from the camera component of the actuator.

[0014] S2. If the cable insulation layer is found to be damaged, tighten the locking screw on the outside of the support sleeve to lock the bending angle of the flexible component. When the clamp assembly is open, it abuts against the corresponding cable and drives the second switch on the operating handle to make the clamp assembly stably clamp the outside of the cable.

[0015] S3. Turn on the hot melt glue gun and drive the first switch on the operating handle to apply glue into the gun head of the hot melt glue gun. Based on the video information collected by the camera component, add insulating glue to the damaged part of the cable.

[0016] S4. Restore the device to its initial state and inspect other locations in the distribution box. If other cable insulation is found to be damaged, repeat S2-S3.

[0017] In summary, the present invention has the following main beneficial effects:

[0018] This solution integrates a hot melt glue gun, clamp assembly, and camera assembly within the actuator. The transmission assembly within the steering base drives the actuator to rotate. By simply extending the operating connecting rod from the cabinet door into the distribution box, a comprehensive inspection of the distribution box can be performed without removing the entire cabinet. The second switch is then activated to clamp the cable requiring repair, and the first switch is activated to apply glue to the clamped cable for repair. The entire operation is convenient and quick, adaptable to narrow maintenance spaces, reduces the workload of maintenance personnel, and ensures maintenance efficiency. Attached Figure Description

[0028] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] like Figure 1 As shown, this invention provides a power distribution room inspection 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 sequentially from the near end to the far end. The steering base 2 is provided with a transmission component for driving the flexible component 4 to rotate in all directions, such as... Figure 2 As shown, the actuator includes a hot melt glue gun 6, a clamp assembly 5 mounted on the hot melt glue gun 6 and arranged parallel to the 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 mounted on the operating handle 1. The operating handle 1 has a first switch and a second switch. The front ends of the first switch and the second switch are respectively connected to a first flexible steel wire shaft and a second flexible steel wire shaft. The first flexible steel wire shaft and the second flexible steel wire shaft pass through the steering base 2, the operating connecting rod 3 and the flexible component 4 in sequence along the axial direction and then pass into the hot melt glue gun 6. The front end of the first flexible steel wire shaft is connected to the glue application assembly of the hot melt glue gun 6 to drive the hot melt glue gun 6 to apply glue. The front end of the second flexible steel wire shaft is connected to the clamp assembly 5 to drive the clamp assembly 5 to open and close. More preferably, in order to avoid interference when the first flexible steel wire shaft and the second flexible steel wire shaft move, the first flexible steel wire shaft and the second flexible steel wire shaft have independent through paths in the flexible component, the operating connecting rod 3 and the steering base 1.

[0030] Specifically, such as Figure 3 and Figure 4As shown, the steering base 2 includes a support sleeve 201, a universal ball joint 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 rotatably engages with the universal ball joint 202. The rear end of the universal ball joint 202 has a connecting part 2021 for connecting with 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 joint 202 and the operating handle 1. For fixed connection, preferably by adhesive fixation, the inner spherical surfaces of the universal ball 202 and the support sleeve 201 cooperate to form a ball joint hinge structure. The locking screw 203 is threaded through the support sleeve 201 and locks into contact with the universal ball 202. The transmission component includes four deflection steel ropes 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 passes through the flexible component 4 and is fixedly set. When operating this device, hold the support sleeve 201 and rotate the operating handle 1. The universal ball 202 rotates within the support sleeve 201 according to the direction of the operating handle 1, pulling the four deflection steel ropes fixed inside. The deflection steel ropes drive the flexible component 4 to rotate in the opposite direction to the rotation of the operating handle 1. Subsequently, the actuator connected to the front end of the flexible component 4 also rotates. The transmission component in the steering base 2 drives the actuator to rotate. Since the actuator integrates a hot melt glue gun 6, a clamping assembly 5, and a camera assembly 7, the camera assembly 7 can be used to conduct a comprehensive inspection of the distribution box without removing the entire distribution cabinet. Specifically, the camera assembly 7 is an endoscopic camera with built-in LED auxiliary imaging. After discovering cable damage, it drives the second switch to clamp the cable that needs repair, and then drives the first switch to apply glue to the clamped cable for repair. The entire operation process is convenient and quick, can adapt to narrow maintenance spaces, reduces the workload of maintenance personnel, and ensures maintenance efficiency.

[0031] like Figure 2 and Figure 8 As shown, the flexible component 4 includes a flexible joint 401 and a connecting seat 402. The two ends of the flexible joint 401 are fixedly connected to the operating connecting rod 3 and the connecting seat 402. The flexible joint 401 and the connecting seat 402 have through holes in the middle for the first and second flexible steel wire shafts to pass through. Each joint of the flexible joint 401 has four through holes along the circumference for the deflection steel rope to pass through. Specifically, the front end and the rear end of the deflection steel rope are connected with knots. The knot at the front end is located on the end face of the frontmost joint of the flexible joint 401, and the knot at the rear end is located on the rear end face of the universal ball 202. The front end of the connecting seat 402 is fixedly connected to the outside of the hot melt glue gun 6 via two brackets arranged side by side. A guide pulley 4021 for winding the first and second flexible steel wire shafts is provided between the two brackets.

[0032] like Figure 2 As shown, the glue application assembly includes a limiting sleeve 602, a moving plate 603, and a glue application 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 glue application path of the glue stick 601. The moving plate 603 is rotatably installed on the rear end of the limiting sleeve 602. The upper end face of the moving plate 603 has a meshing part for clamping the glue stick 601 during the glue application process. The above structure is the same as the existing structure of the hot melt glue gun 6, so it will not be described in detail. It is worth noting that the glue application 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 passes through the hot melt glue gun 6, it passes around the glue application pulley 9 and is fixedly connected to the lower end of the moving plate 603. The moving plate 603 has a hanging hole on the side away from the glue application pulley 9. The hanging hole is connected to the inner wall of the hot melt glue gun 6 via an elastic hook 604.

[0033] like Figure 4 The first switching component that cooperates 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 rotatably connected to the operating handle 1. The upper end of the trigger handle 102 has a connecting hole for connecting to the first flexible steel wire shaft. The operating handle 1 has a connecting post 103 inside. The two ends of the tension spring 104 are respectively connected to the connecting post 103 and the upper end of the trigger handle. When the trigger handle is pulled, the upper end of the trigger handle 102 pulls the first flexible steel wire shaft backward. The first flexible steel wire shaft passes around the gluing pulley 9 and then moves the moving plate 603 and the limiting sleeve 602 forward, completing the gluing operation.

[0034] like Figures 5-7 As shown, the clamp assembly 5 includes a hinge base 503, a first clamp body 501, a second clamp body 502, and a drive block 8. The hinge base 503 is mounted 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 formed in the middle of the hinge base 503. The middle parts of the first clamp body 501 and the second clamp body 502 are hinged to the hinge base 503 via a hinge shaft, and inclined sliding holes 5011 are formed on the surfaces of the first clamp body 501 and the second clamp body 502 located in the hinge base 503. The drive block 8 has sliding shafts 801 formed at both ends that slide in conjunction with the sliding holes 5011. The bottom of the drive block 8 has a drive rod 802 that passes through the axial through hole 5031. The drive rod 802 is fitted with compression springs 803 at both ends that abut against the drive block 8 and the hinge seat 503, respectively. The hot melt glue gun 6 is equipped with a steering pulley assembly 10. After the front end of the second steel wire flexible shaft passes through the hot melt glue gun 6, it passes around the steering pulley assembly 10 and passes through the hinge seat 503 and is fixedly connected to the drive rod 802.

[0035] like Figure 4The second switching component that cooperates with the clamp assembly 5 includes a pull rod 105 and a sliding seat 101 fixed to 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 a positioning frame 1011 in a direction away from the operating handle 1. The pull rod 105 has a limiting plate 1051 on its outer side that abuts against the outer end face of the sliding seat 101. The size of the limiting 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 drive block 8 is located below the hinge shaft near clamp body 1 501 and clamp body 2 502 under the elastic force of the compression spring 803. At this time, the sliding shaft 801 of the drive block 8 is located at the front end of each sliding hole 5011. Clamp body 1 501 and clamp body 2 502 are in the open state. In this state, they are connected to the outside of the cable to be repaired. Pull the pull rod 105 until the limiting plate 1051 reaches the outside of the positioning frame 1011. At this time, rotate the pull rod 105. Since the size of the limiting plate 1051 is larger than the width of the positioning frame 1011, the limiting plate 1051 restricts the pull rod 105 to this position. Under the pull of the pull rod 105, the front end of the second steel wire flexible shaft drives the drive block 8 to move backward. The sliding shaft 801 slides along the sliding hole 5011 to drive the two clamp bodies to close, completing the clamping action of the cable.

[0036] To facilitate the glue application process, the nozzle of the hot melt glue gun 6 can move within a certain range, thereby ensuring the glue application area, as shown in the figure. Figures 5-7 As shown, a deflection seat 504 is fixed at the connection between the hot melt glue gun 6 and the hinge seat 503. The deflection seat 504 has a coaxial hole 5041 in the middle that communicates with the axial through hole 5031. The front end of the deflection seat 504 and the rear end of the hinge seat 503 have ear seats 12 that are hinged to each other. Springs 11 are provided on both sides of the coaxial hole 5041, with their two ends connected to the deflection seat 504 and the hinge seat 503 respectively. Specifically, the hinge axis between the clamp bodies and the hinge axis between the ear seats 12 are set perpendicularly. The clamp assembly 5 moves around the hinge center of the ear seats 12 towards or away from the head of the hot melt glue gun 6.

[0037] When construction workers inspect and maintain the power distribution room, they use the aforementioned power distribution room inspection and maintenance devices. The operating procedures are as follows:

[0038] S1. Insert the operating connecting rod 3 into the distribution box, hold the support sleeve 201, and rotate the operating handle 1 to drive the universal ball 202 to rotate, thereby driving the flexible component 4 and its connected actuator to rotate in the opposite direction. The display control unit 701 can view the video information collected from the camera component 7 of the actuator.

[0039] S2. If the cable insulation layer is found to be damaged, tighten the locking screw 203 on the outside of the support sleeve 201 to lock the bending angle of the flexible component 4. When the clamp component 5 is open, it abuts against the corresponding cable and drives the second switch on the operating handle 1 to make the clamp component 5 stably clamp the outside of the cable.

[0040] S3. Turn on the hot melt glue gun 6 and drive the first switch on the operating handle 1 to apply glue into the gun head of the hot melt glue gun 6. Based on the video information collected by the camera component 7, add insulating glue to the damaged part of the cable.

[0041] S4. Restore the device to its initial state and inspect other locations in the distribution box. If other cable insulation is found to be damaged, repeat S2-S3.

[0042] This device can perform a comprehensive inspection of the distribution box without removing the entire distribution cabinet, and can perform cable repair by applying glue with the cooperation of the first and second switching components. It can adapt to narrow maintenance spaces, reduce the workload of maintenance personnel, and ensure maintenance efficiency.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the principles of the present invention should be included within the scope of protection of the present invention.
