Description

An easily replaceable lightning protection device for tower poles Technical Field

[0001] This invention relates to the field of lightning rod maintenance, and in particular to an easily replaceable lightning protection device for towers. Background Technology

[0002] A lightning rod is a device used to protect buildings, tall trees, and other structures from lightning strikes. It is usually installed at the highest point of the object to be protected. It guides lightning to discharge to the lightning rod, and then conducts the lightning current to the ground through the grounding down conductor and grounding device, thereby protecting the object from lightning strikes.

[0003] Traditional lightning rods are typically fixed to buildings. However, prolonged exposure to the elements can lead to weathering, corrosion, and other damage, rendering them ineffective at preventing lightning strikes. In such cases, maintenance is necessary. Traditional maintenance methods require workers to climb to the top of the building for high-altitude work, which is not only cumbersome but also poses significant safety hazards.

[0016] As a preferred embodiment of the easily replaceable tower lightning protection device of the present invention, the base is provided with a fixed base at the bottom and an inspection window is provided on the side wall of the base.

[0017] The beneficial effects of this invention are:

[0018] The device of this invention is equipped with a lifting rod and a drive motor. The lightning rod is installed on the lightning protection connecting seat, which is slidably connected to the lifting rod. When the lightning rod needs to be replaced, only the drive motor needs to be started, and the lightning protection connecting seat can be driven to slide up and down along the lifting rod by the drive motor. This allows for quick and easy replacement of the lightning rod without the need for workers to climb to the top of the building for high-altitude operations, thereby improving maintenance efficiency and reducing safety hazards.

[0019] Furthermore, the present invention forms a driving device by cooperating a drive motor and a lead screw. The lead screw and the lifting sleeve are connected by a threaded pair to convert the rotational motion of the drive motor into linear motion, which transports the lightning protection connecting seat to the top of the lifting rod or lowers it to the bottom. The structure is simple and easy to implement.

[0020] Furthermore, this invention achieves rapid fixing and unlocking of the lightning arrester connecting seat through the cooperation of the locking pin on the lightning arrester connecting seat with the locking block and unlocking block on the lifting rod. When the lightning arrester connecting seat rises until the locking pin contacts the locking block, as the lightning arrester connecting seat continues to rise, the telescopic spring is continuously compressed, causing the locking pin to be continuously pressed into the locking groove until the locking pin is completely pressed into the locking groove and moves above the locking block. Then, the locking pin pops out again under the action of the telescopic spring, and the lightning arrester connecting seat is fixed by the cooperation of the lower surface of the locking pin and the upper surface of the locking block, thus completing the installation of the lightning rod. When the lightning rod needs maintenance or replacement, the lightning arrester connector will continue to move upward a certain distance under the drive of the lead screw. During this upward movement, the locking pin is continuously pressed back into the locking groove by the pressure of the unlocking block. Once the locking pin is fully pressed into the locking groove and moves above the unlocking block, the lightning arrester connector is lowered. Since the unlocking spring is easier to compress than the telescopic spring, the locking pin will first drive the unlocking block downward when it descends. Only after the unlocking spring can no longer be compressed will the descending of the locking pin cause the telescopic spring to begin to compress, pressing the locking pin back into the locking groove. The locking pin will then descend directly below the locking block before popping out. At this point, the unlocking of the lightning arrester connector is complete. The lightning arrester connector descends to the bottom of the lifting rod, allowing workers to directly perform maintenance work on the lightning rod from the ground. Therefore, this invention only requires operating the drive motor to quickly fix and unlock the lightning arrester connector, requiring no manual operation. Furthermore, the fixing method of the lightning arrester connector in this invention is robust and reliable.

[0021] Furthermore, the present invention also provides a limiting rod on the lifting rod and a straight groove on the lightning protection connecting seat. During the process of the locking pin moving above the locking block and popping out again, the locking pin will press the limiting rod back into the limiting groove. Then the other end of the limiting rod passes through the side wall of the track groove and inserts into the straight groove of the connecting plate on the lightning protection connecting seat, thereby realizing the secondary fixation of the lightning protection connecting seat and further ensuring the stability of the lightning rod installation.

[0022] Furthermore, the invention provides a baffle at the top of the lifting rod to limit the movement distance of the lightning protection connector, preventing workers from accidentally disengaging the lightning protection connector from the lifting rod. At the same time, the buffer spring can cushion the rising lightning protection connector, preventing it from colliding with the baffle at too high a rising speed and causing damage to the lightning rod.

[0023] Furthermore, the present invention provides an inspection window on the base, through which the working condition of the cables on the support assembly can be preliminarily judged, and it can be determined whether maintenance work is required. Attached Figure Description

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0036] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0037] Example 1

[0038] Referring to Figures 1-3, this embodiment provides an easily replaceable tower lightning protection device, including a support assembly 100, a base 101 at the bottom of the support assembly 100, a plurality of fixing rings 102 connected to the support assembly 100, and a lifting rod 103 fixedly connected to the fixing rings 102; and a disassembly assembly 200, including a lightning protection connecting seat 201 connected to the lifting rod 103, and a lightning rod 202 fixedly connected to the lightning protection connecting seat 201.

[0039] Specifically, the support component 100 is part of the transmission tower, and cables are laid on it during use. Therefore, in order to prevent the support component 100 from being struck by lightning, a lightning protection device needs to be installed on the top of the support component 100. In order to prevent the performance of the lightning protection device from deteriorating and its lightning protection ability from weakening after long-term use, the lightning protection device needs to be inspected or replaced regularly. Traditional maintenance operations require workers to climb to the top of the support component 100, which poses a significant safety hazard. However, the lifting rod 103 installed on the support component 100 can easily transport the lightning protection device to the top of the support component 100, which not only improves the efficiency of maintenance but also prevents safety accidents.

[0040] Preferably, after the lightning protection connector 201 is delivered to the top of the lifting rod 103, the lightning protection connector 201 can be firmly fixed to the top of the support assembly 100 through the cooperation of the lifting rod 103 and the lightning protection connector 201, and ensure that the lightning rod 202 is always in the vertical direction, so as to achieve the maximum lightning protection effect.

[0041] Furthermore, a grounding wire is installed inside the lifting rod 103 to guide the ground. The grounding wire is electrically connected to the lightning protection connector 201. When the lightning rod 202 is fixed on the lightning protection connector 201, the grounding wire is connected to the lightning rod 202. Therefore, lightning is guided to the ground through the grounding wire, preventing the cable on the support component 100 from being electrocuted and broken down.

[0042] By installing this device, the efficiency of lightning rod maintenance is greatly improved, lightning rod replacement is achieved quickly, and the manual disassembly and assembly of lightning rods is eliminated, further enhancing safety performance.

[0043] Example 2

[0044] Referring to Figures 2-4, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a fixed base 101a is provided at the bottom of the base 101, an inspection window 101b is provided on the side wall of the base 101, and mounting brackets 101c are evenly arranged around the top of the base 101. A drive motor 101d is fixedly connected to the mounting bracket 101c. The drive motor 101d is provided with an output shaft 101d-1, and connecting grooves 101d-2 are symmetrically arranged on the output shaft 101d-1; fixing sleeves 102a are evenly arranged on the fixing ring 102, and the fixing sleeves 102a are secured by a ring lock. 102b is connected to the fixed ring 102; the lifting rod 103 is fixed by the fixed sleeve 102a, the lifting rod 103 is provided with a lead screw 103a, the bottom of the lead screw 103a is symmetrically provided with a square platform 103a-1, the top of the lifting rod 103 is provided with a baffle 103b, the baffle 103b is provided with a buffer spring 103b-1, and the two sides of the lifting rod 103 are provided with track grooves 103c; the output shaft 101d-2 is connected to the lead screw 103a through a coupling 104, the inner wall of one end of the coupling 104 is symmetrically provided with a boss 104a, and the inner wall of the other end of the coupling 104 is symmetrically provided with a square groove 104b.

[0045] Specifically, the working condition of the cables on the support component 100 can be initially determined through the inspection window 101b, and it can be determined whether maintenance work is required.

[0046] Preferably, the shape of the boss 104a matches the shape of the connecting groove 101d-2 on the output shaft 101d-1, and the shape of the square groove 104b matches the shape of the platform 103a-1 on the lifting rod 103. Therefore, by setting a coupling 104 between the output shaft 101d-1 and the lead screw 103a, the torque output by the output shaft 101d-1 can be transmitted to the lead screw 103a without loss. Then, by rotating the lead screw 103a, the lifting function of the lifting rod 103 can be realized. By driving the lead screw to rotate forward and backward by the drive motor 101d, the lifting of the lightning protection connecting seat 201 can be realized.

[0047] Furthermore, the baffle 103b at the top of the lifting rod 103 can limit the movement distance of the lightning protection connecting seat 201, preventing the lightning protection connecting seat 201 from being accidentally disengaged from the lifting rod 103 by the staff. At the same time, the buffer spring 103b-1 can buffer the rising lightning protection connecting seat 201, preventing the lightning protection connecting seat 201 from rising too fast and colliding with the baffle 103b, causing damage to the lightning rod 202.

[0048] By setting up the support component 100, the lightning protection connection seat 201 can be fixed and raised at the same time, eliminating the need for workers to carry the lightning rod 202 to the top of the tower, which greatly improves safety.

[0049] Example 3

[0050] Referring to Figures 5-8, this is the third embodiment of the present invention. This embodiment provides an easily replaceable tower lightning protection device. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: an unlocking groove 103d is provided in the track groove 103c, an unlocking block 103d-1 is provided in the unlocking groove 103d, an unlocking spring 103d-2 arranged vertically is fixedly connected to the bottom of the unlocking block 103d-1, a locking block 103e is provided below the unlocking groove 103d, a limiting groove 103f is also provided on the side wall of the track groove 103c, a limiting rod 103g is provided in the limiting groove 103f, a limiting spring 103g-1 is sleeved on the limiting rod 103g, a slope 103g-2 is provided at one end of the limiting rod 103g, and a protrusion 103g-3 is symmetrically provided at the other end of the limiting rod 103g; the lightning protection connection seat 201 includes a main board 201a, side plates 201b are provided at both ends of the main board 201a, and the side plates... 201b is also equipped with a connecting plate 201c; the outer wall of the main board 201a is equipped with a connecting sleeve 201a-1, into which the lightning rod 202 is inserted; the inner wall of the main board 201a is equipped with a lifting sleeve 201a-2, and the inner wall of the lifting sleeve 201a-2 is equipped with a thread 201a-3; the inner side of the side plate 201b is equipped with a locking groove 201d, and the bottom of the locking groove 201d is also equipped with a lock hole 201d-1, which is located inside the locking groove 201d. A locking pin 201e is provided, and a locking post 201e-1 is provided at the bottom of the locking pin 201e to cooperate with the lock hole 201d-1. A telescopic spring 201e-2 is sleeved on the locking post 201e-1. The inner diameter of the telescopic spring 201e-2 is larger than that of the lock hole 201d-1, and the locking post 201e-1 can be inserted into the lock hole 201d-1. A straight groove 201c-1 is provided on the connecting plate 201c, and positioning grooves 201c-2 are provided on both sides of the straight groove 201c-1.

[0051] Specifically, the width of the track groove 103c is the same as the width of the locking pin 201e on the lightning protection connector 201. The locking pin 201e embedded in the track groove 103c limits the lightning protection connector 201 to prevent it from falling off the lifting rod 103. At the same time, the lifting sleeve 201a-2 can extend into the lifting rod 103 and be sleeved on the screw 103a. The lifting and lowering of the lightning protection connector 201 can be realized through the engagement of the screw 103a with the thread 201a-3 on the lifting sleeve 201a-2.

[0052] Preferably, the inclined angles of the locking pin 201e, the unlocking block 103d-1, and the inclined surfaces of the locking block 103e are the same, and the inclined surfaces of the locking block 103e and the unlocking block 103d-1 are set opposite to each other. The force required to compress the unlocking spring 103d-2 is less than the force required to compress the telescopic spring 201e-2. Therefore, when the locking pin 201e applies pressure to the unlocking block 103d-1, it will first compress the unlocking spring 103d-2 to make the unlocking block 103d-1 drop. Only when the unlocking spring 103d-2 is fully compressed and pressure is continued will the telescopic spring 201e-2 be compressed.

[0053] Furthermore, the protrusion 103g-3 on the limiting rod 103g is embedded in the positioning groove 201c-2, which can ensure that the limiting rod 103g will not rotate during movement, so that the inclined surface 103g-2 always faces the outside of the track groove 103c.

[0054] In this embodiment, the lightning rod 202 is first transported to the top of the lifting rod 103. At this time, the drive motor 101d is started. The torque output by the drive motor 101d is transmitted to the lead screw 103a through the output shaft 101d-1. The forward rotation of the lead screw 103a drives the lightning protection connecting seat 201 to rise. When the lightning protection connecting seat 201 rises until the locking pin 201e contacts the locking block 103e, the lightning protection connecting seat 201 continues to rise. The telescopic spring 201e-2 is continuously compressed, causing the locking pin 201e to be continuously pressed into the locking groove 201d. After the locking pin 201e is completely pressed into the locking groove 201d and moves above the locking block 103e, the locking pin 201e pops out again under the action of the telescopic spring 201e-2. The lightning protection connecting seat 201 is fixed by the cooperation between the lower surface of the locking pin 201e and the upper surface of the locking block 103e, thus completing the installation of the lightning rod 202.

[0055] Preferably, during the process of the locking pin 201e moving above the locking block 103e and popping out again, the locking pin 201e will press the limiting rod 103g back into the limiting groove 103f. Then, the other end of the limiting rod 103g passes through the side wall of the track groove 103c and inserts into the straight groove 201c-1 of the connecting plate 201c, completing the secondary fixation of the lightning rod 202 and ensuring the stability of the installation of the lightning rod 202.

[0056] When inspecting or replacing the lightning rod 202, first, continue rotating the drive motor 101d forward. The lightning arrester connector 201 will then move upward a short distance under the influence of the lead screw 103a. During this upward movement, the locking pin 201e is continuously pressed back into the locking groove 201d by the pressure of the unlocking block 103d-1. Once the locking pin 201e is fully pressed into the locking groove 201d and moves above the unlocking block 103d-1, reverse the drive motor 101d. The lightning arrester connector 201 will then begin to descend due to the reverse rotation of the lead screw 103a. Since the unlocking spring 103d-2 is more easily compressed than the telescopic spring 201e-2,… When the locking pin 201e descends, it will first cause the unlocking block 103d-1 to move down until the unlocking spring 103d-2 can no longer be compressed. Only then will the descent of the locking pin 201e cause the telescopic spring 201e-2 to start compressing and press the locking pin 201e back into the locking groove 201d. Then the locking pin 201e will descend directly to the bottom of the locking block 103e before it pops out. At this point, the unlocking of the lightning rod connecting seat 201 is completed. The reverse rotation of the lead screw 103a can directly drive the lightning rod connecting seat 201 down to the bottom of the lifting rod 103. The staff can directly carry out maintenance work on the lightning rod on the ground, which greatly improves the efficiency of maintenance.

[0057] By setting up the disassembly component 200, the installation and disassembly of the lightning rod 202 can be completed simply by moving the lightning protection connector 201 up and down on the lifting rod 103, which greatly improves the replacement efficiency of the lightning rod. Moreover, the staff only needs to control the forward and reverse rotation of the drive motor 101d throughout the process, which is not only convenient to operate, but also reduces safety hazards.
