Description

Technical Field

[0001] The present invention relates to the technical field of power grid data observation, and in particular to a transmission line overload testing and maintenance device. Background Art

[0002] In the power system, transmission line is a general term for facilities and equipment that connect power generation and power consumption. It is an intermediate link in the transmission and distribution of electric energy. It is mainly composed of transmission lines, substations, distribution stations and distribution lines connected into a network. The unified whole that connects power generation and power consumption, composed of transmission, substation, distribution equipment and corresponding auxiliary systems, is usually called a power grid, or grid for short. Overload of transmission lines often occurs in the grid, resulting in line damage. Workers need to use transmission line overload testing and maintenance devices. The overload testing and maintenance devices usually use a tool box as a carrier, and the box contains overload testers and common tools required for maintenance.

[0003] In order to make full use of the space inside the box, the existing overload testing and maintenance devices will adopt a drawer structure to set up multiple layers of space for placing tools. Among them, the maintenance tools are mostly flat structures such as screwdrivers, wrenches, etc., which result in these tools being only located in the bottom space inside the drawer. Therefore, only the bottom space of each layer of the drawer is often used, and the middle and upper spaces in the drawer are often idle.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a transmission line overload testing and maintenance device is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a transmission line overload testing and maintenance device in view of the existing technical status.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme: A power transmission line overload testing and maintenance device comprises a tool box body and a maintenance component, wherein slide rails are fixed on both sides of the inner wall of the tool box body, the maintenance component is arranged on the sides of the slide rails, and the maintenance component is slidably connected to the tool box body through the slide rails, the maintenance component comprises a sliding drawer, a torsion spring shaft, a carrier plate, a first elastic tightening band and a rotating pressure rod, both sides of the inner wall of the sliding drawer are elastically connected to the carrier plate through the torsion spring shaft, and the upper and lower surfaces of the carrier plate are both provided with a first elastic tightening band, a maintenance tool is passed between the first elastic tightening band and the carrier plate, and the front end of the inner wall of the tool box body is rotatably connected to the rotating pressure rod above the sliding drawer.

[0007] Furthermore, a tray assembly is arranged on the upper part of the inner wall of the tool box, and the tray assembly includes a hollow frame and a loading tray, and the loading tray is arranged inside the hollow frame.

[0008] Furthermore, the tray assembly also includes a second elastic tightening belt, and the bottom of the inner wall of the cargo tray is provided with a second elastic tightening belt.

[0009] Furthermore, a damping shaft is arranged on the upper back side of the tool box body, and an outer wall of the damping shaft is connected to an overload test component.

[0010] Furthermore, the overload test assembly includes a tool box cover, a partition, a battery and a touch screen. A partition is provided in the middle of the inner wall of the tool box cover, and a battery is fixed on one side of the partition. The battery is connected to the touch screen through a wire.

[0011] Furthermore, the touch screen is located on a side of the partition away from the battery, and the touch screen is embedded in the tool box cover.

[0012] Furthermore, the overload test assembly also includes a rotary spring shaft, and the rotary spring shaft is distributed in parallel on one side of the battery, and the rotary spring shaft is elastically rotatably connected to the partition.

[0013] Furthermore, the overload test assembly also includes a test circuit and a plug connector. The test circuit is wound on the surface of the rotary spring shaft, one end of the test circuit is connected to the plug connector, and the other end of the test circuit is connected to the touch screen.

[0014] Furthermore, a detection head is plugged into the plug connector, and the detection head is separately placed inside the loading tray.

[0015] Furthermore, the overload test assembly also includes a wire threading hole. The side of the tool box cover is provided with the wire threading hole, and a test circuit is passed through the inside of the wire threading hole.

[0016] The beneficial effects of the present invention are: 1. The present invention provides a power transmission line overload test and maintenance device. The upper surface of the carrier plate in a tilted state is pressed down due to the limit of the rotating pressure rod, thereby causing the torsion spring shaft to enter a power storage state. After the sliding drawer enters the tool box body, the carrier plate is nearly horizontally located on the upper part of the inner wall of the sliding drawer, thereby facilitating full use of the middle and upper space inside the sliding drawer, thereby allowing more flat tools to be stored, thereby reducing the volume of the entire overload test and maintenance device, and making it more convenient to carry. When the sliding drawer is pulled out, the carrier plate automatically rotates and tilts to expose the bottom and the internal space of the sliding drawer, thereby facilitating personnel to take and put tools. 2. The present invention provides a transmission line overload test and maintenance device, in which a detection head is plugged or threadedly connected to a plug connector, and the detection head is connected to a transmission line to be tested. The transmission line is detected by the detection head, and the detection result is fed back through a touch screen. After the detection is completed, the detection head is manually unplugged and the plug connector is loosened. At this time, the rotary spring shaft loses force and rotates in the opposite direction, thereby automatically winding up the redundant test line, which is conducive to neatly and quickly storing the test line and avoiding the test line from being randomly and messily collected manually.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] like Figure 1 to Figure 6As shown, the present invention provides a technical solution: a power transmission line overload testing and maintenance device, comprising a toolbox body 1 and a maintenance component 3, slide rails 2 are fixed on both sides of the inner wall of the toolbox body 1, the maintenance component 3 is arranged on the side of the slide rails 2, and the maintenance component 3 is slidably connected to the toolbox body 1 through the slide rails 2, the maintenance component 3 comprises a sliding drawer 301, a torsion spring shaft 302, a carrier plate 303, a first elastic tightening band 304 and a rotating pressure rod 305, both sides of the inner wall of the sliding drawer 301 are elastically connected with the carrier plate 303 through the torsion spring shaft 302, and the upper and lower surfaces of the carrier plate 303 are both provided with a first elastic tightening band 304, a maintenance tool is inserted between the first elastic tightening band 304 and the carrier plate 303, and the front end of the inner wall of the toolbox body 1 is rotatably connected with the rotating pressure rod 305 above the sliding drawer 301.

[0021] The specific operation is as follows: the flat-structured maintenance tools are not only placed in the internal bottom space of the sliding drawer 301, but also placed on the upper and lower surfaces of the carrier 303, and the maintenance tools are restrained by the elastic action of the first elastic restraining belt 304 to prevent the maintenance tools from sliding and falling off from the upper and lower surfaces of the carrier 303. When the sliding drawer 301 is pulled out, the rotating pressure rod 305 moves from the front end to the rear end above the carrier 303 in disguise, and the front end of the carrier 303 loses force and is tilted upward due to the elastic action of the torsion spring shaft 302, thereby exposing the upper and lower surfaces of the carrier 303 and the tools inside the sliding drawer 301, making it convenient for people to take and put tools.

[0022] When the sliding drawer 301 is pushed back to its original position, the rotating pressure rod 305 moves in disguise from the rear end to the front end above the carrier plate 303, and the upper surface of the carrier plate 303 in a tilted state is pressed down due to the limit of the rotating pressure rod 305, thereby causing the torsion spring shaft 302 to enter a force storage state. After the sliding drawer 301 is reset, the carrier plate 303 is located almost horizontally on the upper part of the inner wall of the sliding drawer 301, which is conducive to making full use of the middle and upper space inside the sliding drawer 301, so that more flat tools can be stored, so as to reduce the volume of the entire overload testing and maintenance device, thereby making it more convenient to carry, and when the sliding drawer 301 is pulled out, the carrier plate 303 automatically rotates and tilts to expose the bottom and the internal space of the sliding drawer 301, thereby facilitating personnel to take and put tools.

[0023] like Figure 1 to Figure 6 As shown, a tray assembly 4 is arranged on the upper part of the inner wall of the tool box body 1, and the tray assembly 4 includes a hollow frame 401 and a loading tray 402. The loading tray 402 is arranged inside the hollow frame 401, and the tray assembly 4 also includes a second elastic tightening belt 403. The bottom of the inner wall of the loading tray 402 is provided with a second elastic tightening belt 403.

[0024] The specific operation is as follows: the loading tray 402 is supported by the hollow frame 401, and the loading tray 402 makes full use of the space above the sliding drawer 301, and the top of the loading tray 402 is relatively lower than the top of the toolbox body 1, that is, the loading tray 402 sinks into the toolbox body 1, and the touch screen 604 is embedded in the toolbox cover 601, that is, the side of the toolbox cover 601 protrudes from the surface of the touch screen 604, then when the toolbox cover 601 and the toolbox body 1 are closed, the side of the toolbox cover 601 is in contact with the top of the toolbox body 1, and the touch screen 604 is suspended above the loading tray 402, thereby avoiding scratches caused by contact between the touch screen 604 and the maintenance tools, wherein the toolbox cover 601 and the toolbox body 1 are fixed by buckles on both sides of the toolbox body 1 after the toolbox cover 601 is closed, and the buckles are not shown in the figure, so as to avoid the toolbox cover 601 from opening and closing at will.

[0025] like Figure 1 to Figure 6 As shown, a damping shaft 5 is arranged on the upper back of the toolbox body 1, and the outer wall of the damping shaft 5 is connected to an overload test component 6, the overload test component 6 includes a toolbox cover 601, a partition 602, a battery 603 and a touch screen 604, a partition 602 is arranged in the middle of the inner wall of the toolbox cover 601, and a battery 603 is fixed on one side of the partition 602, the battery 603 is connected to the touch screen 604 through a wire, the touch screen 604 is located on the side of the partition 602 away from the battery 603, and the touch screen 604 is embedded in the toolbox cover 601, the overload test component 6 also includes a rotary spring shaft 605, one side of the battery 603 is parallel to the A rotary spring shaft 605 is distributed, and the rotary spring shaft 605 is elastically rotatably connected to the partition 602. The overload test component 6 also includes a test circuit 606 and a plug connector 607. The test circuit 606 is rolled up on the surface of the rotary spring shaft 605, and one end of the test circuit 606 is connected to the plug connector 607, and the other end of the test circuit 606 is connected to the touch screen 604. A detection head is plugged into the plug connector 607, and the detection head is separately placed inside the cargo tray 402. The overload test component 6 also includes a threading hole 608. The side of the tool box cover 601 is provided with a threading hole 608, and the test circuit 606 is passed through the threading hole 608.

[0026] The specific operation is as follows. When conducting an overload test on a power transmission line, first open the tool box cover 601 and rotate it to an inclined angle through the damping shaft 5 so that people can comfortably observe the touch screen 604. Manually hold the plug connector 607 and pull it, so that the rotary spring shaft 605 is rotated under force to release the test circuit 606. Then take out the detection head from between the second elastic tightening belt 403 and the loading tray 402, plug or thread the detection head and the plug connector 607, and connect the detection head to the power transmission line to be tested. The transmission line is detected by the detection head, and the detection result is fed back through the touch screen 604, wherein the battery 603 is used to power the touch screen 604.

[0027] After the test is completed, the test head is manually unplugged and the plug connector 607 is loosened. At this time, the rotary spring shaft 605 loses the force and rotates in the opposite direction, thereby automatically reeling in the redundant test circuit 606, which is conducive to neatly and quickly storing the test circuit 606 and avoiding the test circuit 606 from being randomly and messily collected manually.

[0028] In summary, the advantages of the transmission line overload testing and maintenance device are as follows: When the overload test is performed on the transmission line, the tool box cover 601 is first opened to rotate it to an inclined angle through the damping shaft 5 so that people can comfortably observe the touch screen 604. The plug connector 607 is manually held and pulled to make the rotary spring shaft 605 rotate under force to release the test line 606. Then the detection head is taken out from between the second elastic tightening belt 403 and the loading tray 402, and the detection head and the plug connector 607 are plugged or threaded, and the detection head is connected to the transmission line to be tested. The transmission line is detected by the detection head, and the detection result is fed back through the touch screen 604, wherein the battery 603 is used to supply power to the touch screen 604; after the detection is completed, the detection head is manually unplugged and the plug connector 607 is loosened. At this time, the rotary spring shaft 605 loses force and rotates in the opposite direction, thereby automatically rolling up the redundant test line 606, which is conducive to neatly and quickly storing the test line 606 and avoiding the test line 606 from being randomly and messily recycled manually; The flat-structured maintenance tools are not only placed in the inner bottom space of the sliding drawer 301, but also placed on the upper and lower surfaces of the carrier plate 303, and the maintenance tools are bound by the elastic action of the first elastic tightening belt 304 to prevent the maintenance tools from sliding off the upper and lower surfaces of the carrier plate 303. When the sliding drawer 301 is pulled out, the rotating pressure rod 305 moves from the front end to the rear end of the upper part of the carrier plate 303 in disguised form, and the front end of the carrier plate 303 loses force and tilts upwards due to the elastic action of the torsion spring shaft 302, thereby exposing the upper and lower surfaces of the carrier plate 303 and the tools inside the sliding drawer 301, and it is convenient for personnel to take and put tools; When the sliding drawer 301 is pushed back to its original position, the rotating pressure rod 305 moves from the rear end to the front end above the carrier plate 303, and the upper surface of the carrier plate 303 in a tilted state is pressed down due to the limit of the rotating pressure rod 305, thereby making the torsion spring shaft 302 enter a force storage state. After the sliding drawer 301 is completely reset, the carrier plate 303 is almost horizontally located on the upper part of the inner wall of the sliding drawer 301, which is conducive to making full use of the middle and upper space inside the sliding drawer 301. The loading tray 402 is supported by the hollow frame 401, and the loading tray 402 fully utilizes the space above the sliding drawer 301, and the top of the loading tray 402 is relatively lower than the top of the toolbox body 1, that is, the loading tray 402 sinks into the toolbox body 1, and the touch screen 604 is embedded in the toolbox cover 601, that is, the side of the toolbox cover 601 protrudes from the surface of the touch screen 604, then when the toolbox cover 601 and the toolbox body 1 are closed, the side of the toolbox cover 601 is in contact with the top of the toolbox body 1, and the touch screen 604 is suspended above the loading tray 402, thereby avoiding scratches caused by the contact between the touch screen 604 and the maintenance tools.

[0029] The present invention is not limited to the above-mentioned specific implementation modes. A person skilled in the art can implement the present invention in various other specific implementation modes based on the contents disclosed in the present invention.
