Description

Technical Field

[0001] The invention belongs to the technical field of lightning arresters, and in particular relates to a lightning arrester installation device. Background Art

[0002] The construction of a new power system based on renewable energy is an inevitable trend in the upgrading and development of the power grid. With the widespread application of renewable energy generation technologies such as photovoltaic power generation and energy storage devices, and the widespread integration of a high proportion of renewable energy and power electronic equipment, the lightning protection issues of this new power system have become more prominent. The overhead distribution lines of the power grid system are extremely susceptible to lightning strikes and power accidents. Therefore, installing lightning arresters on overhead distribution lines is a common and effective protective measure.

[0003] During a lightning strike, the instantaneous high-voltage current on the overhead distribution line flows through the arrester and into the ground, thereby protecting the insulator from breakdown. Typically, insulators are installed vertically between the high-voltage line and the crossarm of the pole, with the upper end connected to the overhead distribution line and the lower end fixed to the crossarm with bolts and grounded. However, to protect personal safety, power workers need to climb the pole and operate at close range after the line is de-energized during the installation of the arrester. Installation during a power outage typically causes power outages for users, impacting industrial and agricultural production, and affecting power supply reliability and service quality. Live installation does not require a power outage and does not affect normal user use. This is of great significance for improving the quality of power supply services and optimizing the business environment of power companies.

[0004] Moreover, in actual situations, the arrester and insulator are roughly parallel and maintain a certain lateral spacing. The two are installed vertically between the high-voltage line and the crossarm. The drainage wire at the top of the arrester is connected to the cable, and the metal connecting plate at the bottom of the arrester is installed between the insulator and the upper surface of the crossarm. It is fixed to the crossarm together with the insulator by bolts. When installing the arrester, power personnel first loosen the bolts at the bottom of the insulator, then manually lift the insulator upward and insert the lower connecting plate of the arrester between the insulator and the upper surface of the crossarm. Due to the downward pressure of the overhead distribution line, the insulator tilts toward the sides of the overhead distribution line, the gap between the insulator and the crossarm becomes smaller, and the lower connecting plate of the arrester cannot be inserted. It is necessary to lift the insulator upward with force, and then insert the lower connecting plate of the arrester between the insulator and the upper surface of the crossarm. The arrester is adjusted to keep it in a roughly vertical position, and finally the bolts at the bottom of the insulator are tightened. During the entire disassembly and installation process, it is extremely difficult for a single electrician to complete the above disassembly and installation. Usually, two professional electricians are required to cooperate with each other to complete the operation. The operation process is cumbersome, time-consuming and labor-intensive, and the disassembly and installation efficiency is low, which also causes excessive power outages. Therefore, there is an urgent need for an automatic tool for disassembling and installing lightning arresters using the insulating rod operation method to solve the problem of safe and efficient disassembly and installation of lightning arresters.

[0005] Therefore, it is necessary to design a lightning arrester installation device to solve the above-mentioned technical problems. Summary of the Invention

DETAILED DESCRIPTION

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0027] Reference Figures 1 to 3 In some embodiments of the present invention, the installation device includes a fixing mechanism 100 and a connecting mechanism 200 arranged on the fixing mechanism 100, wherein the fixing mechanism 100 includes a main seat 101 and an impactor 102 arranged on the main seat 101; the connecting mechanism 200 includes a bracket assembly 201 and a guide rail assembly 202 arranged on the fixing mechanism 100.

[0028] Reference Figures 1 to 3In some embodiments of the present invention, the bracket assembly 201 includes an upper clamping member 201a and a lower clamping member 201b adapted to fit the lower clamping member 201b. The upper clamping member 201a includes an upper clamping plate 201a-1, a groove 201a-2 at the front end of the upper clamping plate 201a-1, an upper through hole 201a-3 at the end of the upper clamping plate 201a-1, and a long bolt 201a-4 adapted to fit the upper through hole 201a-3. The lower clamping member 201b includes a lower clamping plate 201b-1, a boss 201b-2 fixedly disposed at the front end of the lower clamping plate 201b-1, a lower through hole 201b-3 at the end of the lower clamping plate 201b-1, and an arc groove 201b-4 on the lower clamping plate 201b-1. The upper clamping plate 201a-1 and the lower clamping plate 201b-1 are compatible Z-shaped plates, the groove 201a-2 is opened at the front end of the upper clamping plate 201a-1, the upper through hole 201a-3 is opened at the rear end of the upper clamping plate 201a-1, the boss 201b-2 is opened at the front end of the upper clamping plate 201a-1, the lower through hole 201b-3 is opened at the rear end of the lower clamping plate 201b-1, the lower through hole 201b-3 is compatible with the upper through hole 201a-3, the groove 201a-2 is compatible with the boss 201b-2, one end of the long bolt 201a-4 passes through the lower through hole 201b-3 and the upper through hole 201a-3, and the other end of the long bolt 201a-4 is connected to the impactor 102. When the boss 201b-2 is engaged with the groove 201a-2, the gap formed between the upper clamping plate 201a-1 and the lower clamping plate 201b-1 can fix the pole cross arm to ensure the stability of the bracket assembly 201 during operation.

[0029] Specifically, the upper clamping plate 201a-1 and the lower clamping plate 201b-1 are connected by long bolts 201a-4. When installing, the openings of the upper clamping plate 201a-1 and the lower clamping plate 201b-1 must first be opened on the ground. Then the operator uses the insulating operating rod to capture the crossarm of the pole with the bracket assembly 201, and then uses the lower clamping plate 201b-1 to cling to the side and bottom of the crossarm for positioning. After that, the bolts are impacted by the impactor 102 and tightened. Then, the upper clamping plate 201a-1 will move downward under the action of the long bolts 201a-4 until the installation is completed.

[0030] Reference Figures 1 to 4In some embodiments of the present invention, the fixing mechanism 100 also includes a guide rail assembly 202 arranged on the main seat 101; the guide rail assembly 202 includes a limit block 202a, and a guide rail rod 202b slidably connected to the limit block 202a; the guide rail assembly 202 is provided with two groups, respectively located on both sides of the bracket assembly 201. One side of the limit block 202a is in frictional contact with the upper clamping plate 201a-1, and the other side of the limit block 202a is slidably connected to the guide rail rod 202b. When the upper clamping plate 201a-1 is inserted between the limit blocks 202a on both sides, the friction generated by the two sides of the upper clamping plate 201a-1 and the limit blocks 202a will cause the limit blocks 202a to move along the guide rail rod 202b when the upper clamping plate 201a-1 moves. When the installation is finally completed, the operator applies a pulling force greater than the friction force to cause the limit block 202a to separate from the upper clamping plate 201a-1. The guide rail helps to ensure that the bracket remains in a centered position during the installation process and does not deviate to the sides, thereby ensuring the installation quality. The guide rail assembly 202 can ensure that the upper clamping plate 201a-1 will not rotate under the action of the bolts during the descent process.

[0031] Reference Figures 1 to 5 In some embodiments of the present invention, the fixing mechanism 100 further includes a support assembly 103; the lower clamping member 201b further includes a clamping groove 201b-5 defined on the lower clamping plate 201b-1. The support assembly 103 includes a lower support plate 103a disposed on the main base 101, lower support columns 103b fixedly connected to both ends of the lower support plate 103a, clamping columns 103c fixedly connected to the lower support columns 103b, a base 103d disposed on the main base 101, and a lightning arrester support 103e disposed on the base 103d. The clamping column 103c is adapted to the support groove 201b-5, and the diameter of the lower support column 103b is larger than the diameter of the clamping column 103c. When the clamping column 103c is inserted into the support groove 201b-5, the lower support column 103b will support the lower clamping plate 201b-1; one end of the lightning arrester support 103e is fixedly connected to the base 103d, and the other end of the lightning arrester support 103e contacts the bottom surface of the lower clamping plate 201b-1.

[0032] The lower support plate 103a is fixedly connected to the main base 101 and is inserted into the clamping groove 201b-5 through the lower clamping column 103c, which helps to ensure that the lower clamping plate 201b-1 will not tilt due to imbalance, thereby avoiding affecting the installation effect. The base 103d is fixedly connected to the main base 101. The lightning arrester support 103e mainly supports the redundant bolts and nuts at the fixing points of the lightning arrester and the lower clamping plate 201b-1. By fixing the lightning arrester to the lower clamping plate 201b-1, it is beneficial to improve the fixing reliability of the lightning arrester and the connecting mechanism 200, further ensuring the installation quality of high-altitude operations.

[0033] Reference Figures 1 to 6 In some embodiments of the present invention, the fixing mechanism 100 further includes a control assembly 104 and a clamping assembly 105 disposed on the control assembly 104. The clamping assembly 105 is provided in two groups, one on each side of the control assembly 104. The control assembly 104 is used to drive the clamping assembly 105 to clamp the lightning arrester. The control assembly 104 includes an electric push rod 104a and a push plate 104b fixedly connected to the electric push rod 104a.

[0034] Reference Figures 1 to 6 In some embodiments of the present invention, the clamping assembly 105 includes a connecting plate 105a rotatably connected to the push plate 104b, a moving plate 105b rotatably connected to the connecting plate 105a, a limiting plate 105c slidably connected to the moving plate 105b, a rotating plate 105d rotatably connected to the moving plate 105b, a clamping jaw 105e rotatably connected to the rotating plate 105d, a clamping seat 105f rotatably connected to the rotating plate 105d, and a connecting plate 105g fixedly connected to the clamping seat 105f. The clamping end of the clamping jaw 105e is arc-shaped; the rotating plate 105d is rotatably connected to the clamping seat 105f; one end of the connecting plate 105g is fixedly connected to the clamping seat 105f; and the other end of the connecting plate 105g is fixedly connected to the limiting plate 105c. The electric push rod 104a is fixedly connected to the side wall of the main base 101, and the output end of the electric push rod 104a passes through the side wall of the main base 101 and is fixedly connected to the push plate 104b. The limit plate 105c can make the movable plate 105b only move toward the center or sideways on the limit plate 105c. Then, when the output end of the electric push rod 104a drives the push plate 104b to move, the push plate 104b moves and drives the connecting plate 105a to move. The movement of the connecting plate 105a drives the movable plate 105b to move sideways on the limit plate 105c. The movement of the movable plate 105b to the side drives the rotating plate 105d to rotate, and then drives the clamping claw 105e to move toward the center, so that the clamping claws 105e on both sides clamp the lightning arrester, which is beneficial to enhance the stability of the lightning arrester.

[0035] During the operation, first, the operator clamps and fixes the lightning arrester and bracket assembly 201 on the ground and then debugs the device; secondly, the operator holds the insulating operating rod to lift the device, and manually adjusts the position so that the connecting bracket captures the crossarm of the pole; then the impactor 102 (impact wrench) is started to tighten and impact, and the upper clamping plate 201a-1 in the bracket assembly 201 moves downward under the action of the long bolt 201a-4, and the limit blocks 202a on both sides follow and move downward to ensure that the upper clamping plate 201a-1 will not rotate with the long bolt 201a-4; finally, when the bracket assembly 201 is installed, the lightning arrester clamping structure is unlocked and the device is pulled down and disengaged.

[0036] In summary, the bracket assembly 201 can ensure the stability of the upper clamping plate 201a-1 and the lower clamping plate 201b-2 during the installation process; the clamping assembly 105 can effectively clamp lightning arresters of multiple sizes through three-point positioning; first, the support assembly 103 is used to position the bottom bolts of the lightning arrester, and then the space connecting plate 105a structure is used to realize the synchronous opening and closing of the left and right clamping jaws 105e. The arc-shaped design of the clamping jaws 105e can make the clamping structure adaptable to lightning arresters of various sizes; the guide rail assembly 202 can ensure that the bracket assembly 201 remains in the center position during the installation process and does not deviate to the sides, thereby ensuring the installation quality of the lightning arrester; the present invention has a smart structure and is easy to use, reduces the labor burden of the operator, and greatly improves work efficiency.
