Description

Technical Field

[0001] The present invention relates to the field of lightning rod maintenance, and particularly to a lightning protection device for a tower that is easy to replace.

Background Art

[0002] A lightning rod is a device for protecting buildings, tall trees, etc. from lightning strikes. Generally, it is installed at the highest position of the object to be protected, guides the lightning and discharges it towards the lightning rod, and then introduces the lightning current into the ground through the grounding down-conductor and the grounding device, thereby avoiding lightning strikes on the protected object.

[0003] Conventional lightning rods are generally fixedly attached to buildings. However, if a lightning rod is exposed to the outside for a long time, it may be affected by factors such as weathering and corrosion, and may lose its lightning protection function. In this case, the lightning protection device must be inspected and repaired. In the conventional inspection and repair method, the operator has no choice but to climb to the top of the building to perform high-altitude operations, which is not only complicated in operation but also poses a great danger to safety.

[0016] As a further preferred solution for the easily replaceable lightning protection device for transmission towers described in this invention, a fixed base is provided at the lower part of the base, and an inspection window is provided on the side wall of the base.

[0017] The beneficial effects of this invention are as follows: In the device according to this invention, a lifting rod and a drive motor are provided, the lightning rod is attached to a lightning rod connection base, and the lightning rod connection base is slidably connected to the lifting rod. When it is necessary to replace the lightning rod, simply starting the drive motor will drive the lightning rod connection base, which will slide up and down along the lifting rod. This enables the rapid replacement of the lightning rod, eliminating the need for workers to climb to the top of the building to perform work at height, thereby improving inspection and repair efficiency while reducing safety risks.

[0018] Furthermore, this invention constructs a drive device by combining a drive motor and a threaded rod. The threaded rod and lifting sleeve work together with the screw pair to convert the rotational motion of the drive motor into linear motion, transporting the lightning protection connection base to the top of the lifting rod or lowering it to the bottom. The structure is simple and easy to implement.

[0019] Furthermore, this invention enables rapid locking and unlocking of the lightning protection connection base through the cooperation of the lock pin of the lightning protection connection base and the lock block and unlock block of the lifting rod. As the lightning protection connection base rises until the lock pin contacts the lock block, the expansion and contraction spring is continuously compressed, pushing the lock pin further into the lock groove. This continues until the lock pin is fully pushed into the lock groove and moves above the lock block. At this point, the lock pin springs out again, and the lower surface of the lock pin engages with the upper surface of the lock block, fixing the lightning protection connection base and completing the installation of the lightning rod. When the lightning rod needs to be inspected, repaired, or replaced, the lightning connection base is driven by a threaded rod and moves upward for a certain distance. During this movement, the lock pin is continuously pushed back into the lock groove by the pressure of the unlock block. Once the lock pin is fully pushed into the lock groove and moves above the unlock block, the lightning connection base is lowered. As the lock spring is compressed more easily than the expansion spring, the lock pin drives the unlock block downward first as it descends. This continues until the lock spring can no longer be compressed. At this point, the expansion spring begins to compress as the lock pin descends, pushing the lock pin back into the lock groove. Thus, the lock pin descends directly below the lock block and can then pop out. At this point, the lightning connection base is unlocked, and it has descended to the bottom of the lifting rod, allowing the worker to directly perform maintenance on the lightning rod from the ground. As can be seen from this, this invention enables rapid fixing and unlocking of the lightning protection connection base simply by operating the drive motor, requiring no manual operation whatsoever, and the fixing method of the lightning protection connection base of this invention is robust and highly reliable.

[0020] Furthermore, this invention provides a limiting rod on the lifting rod and a straight groove on the lightning rod connection base. In the process of the lock pin moving above the lock block and then popping out again, the lock pin pushes the limiting rod back into the limiting groove. In this way, the other end of the limiting rod passes through the side wall of the track groove and is inserted into the straight groove of the connection plate on the lightning rod connection base. This achieves secondary fixing of the lightning rod connection base and further ensures the stability of the lightning rod mounting.

[0021] Furthermore, by providing a baffle plate at the top of the lifting rod, this invention limits the movement distance of the lightning protection connection base, preventing the lightning protection connection base from detaching from the lifting rod due to operator error. At the same time, the buffer spring cushions the rising lightning protection connection base, preventing the lightning protection connection base from colliding with the baffle plate due to excessive upward speed and damaging the lightning rod.

[0022] Furthermore, this invention includes an inspection window in the base, which allows for a preliminary assessment of the operating state of the cables on the support assembly and a determination of whether inspection or repair work is necessary. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0024] In order to make the above objects, features and advantages of the present invention clearer and easier to understand, the specific embodiments of the present invention will be described in detail below while referring to the drawings in the specification.

[0025] In the following description, many specific details are shown to make the present invention easier to understand. However, the present invention may be implemented in other modes different from those described in this specification, and those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Next, the present invention will be described in detail with reference to the schematic diagrams. When the embodiments of the present invention are described in detail, for the sake of facilitating the explanation, the cross-sectional views showing the device structure are not partially enlarged according to a general ratio, and the above schematic diagrams are merely illustrative and should not be used to limit the protection scope of the present invention. Also, in actual manufacturing, the three-dimensional space dimensions of length, width and depth should be included.

[0027] Furthermore, the terms “one embodiment” or “example” as used herein refer to specific features, structures, or characteristics that may be included in at least one embodiment of the present invention. The phrase “in one embodiment” appearing elsewhere in this specification does not necessarily refer to the same embodiment, nor does it refer to a single embodiment that is mutually exclusive or an optional embodiment.

[0028] Example 1 Referring to Figures 1 to 3, this embodiment provides an easily replaceable lightning protection device for a transmission tower, the device comprising: a support assembly 100, the lower part of which a base 101 is provided, and several fixing rings 102 are connected to the support assembly 100, to which a lifting rod 103 is fixedly connected; and a removal assembly 200, which includes a lightning protection connection base 201 connected to the lifting rod 103, to which a lightning protection connection base 201 is fixedly connected.

[0029] Specifically, the support assembly 100 is part of a power transmission tower, and cables are installed on the support assembly 100 when it is in use. Therefore, to prevent lightning strikes on the support assembly 100, a lightning protection device needs to be installed on top of the support assembly 100. In order to prevent the performance of the lightning protection device from deteriorating and the lightning protection capacity from decreasing after long-term use, the lightning protection device needs to be inspected, repaired, or replaced periodically. However, conventional inspection and repair work requires workers to climb to the top of the support assembly 100, which poses a significant safety risk. In contrast, the lifting rod 103 installed on the support assembly 100 allows the lightning protection device to be easily transported to the top of the support assembly 100, improving the efficiency of inspection and repair and eliminating the occurrence of safety accidents.

[0030] Preferably, after the lightning protection connection base 201 is transported to the top of the lifting rod 103, the fitting of the lifting rod 103 and the lightning protection connection base 201 securely fixes the lightning protection connection base 201 to the top of the support assembly 100, ensuring that the lightning rod 202 is always positioned vertically and achieving the maximum lightning protection effect.

[0031] Furthermore, a grounding wire is provided inside the lifting rod 103, which is connected to the ground. The grounding wire is electrically connected to the lightning protection connection base 201, and when the lightning rod 202 is fixed to the lightning protection connection base 201, the grounding wire is connected to the lightning rod 202, so that lightning is guided to the ground through the grounding wire, preventing the cables on the support assembly 100 from being penetrated by electric shock.

[0032] By installing this device, the efficiency of inspecting and repairing the lightning rod 202 is greatly improved, the lightning rod 202 can be replaced quickly, and the manual removal and installation of the lightning rod 202 is eliminated, further improving safety performance.

[0033] Example 2 Referring to Figures 2 to 4, a second embodiment of the present invention is shown, which is based on the previous embodiment and differs from the previous embodiment in the following respects: A fixed base 101a is provided at the lower part of the base 101, an inspection window 101b is provided on the side wall of the base 101, a mounting frame 101c is provided evenly in an annular shape at the upper part of the base 101, a drive motor 101d is fixedly connected to the mounting frame 101c, an output shaft 101d-1 is provided on the drive motor 101d, and a connection groove 101d-2 is provided symmetrically on the output shaft 101d-1. Fixed sleeves 102a are evenly distributed on the fixed ring 102, and the fixed sleeves 102a are connected to the fixed ring 102 by annular locks 102b. The lifting rod 103 is fixed by the fixed sleeves 102a, a threaded rod 103a is provided inside the lifting rod 103, and square bases 103a-1 are symmetrically provided on the lower part of the threaded rod 103a, a baffle plate 103b is provided on the upper part of the lifting rod 103, a buffer spring 103b-1 is provided on the baffle plate 103b, and raceway grooves 103c are provided on both sides of the lifting rod 103, the output shaft 101d-2 is connected to the threaded rod 103a via a coupling 104, a boss 104a is symmetrically provided on the inner wall of one end of the coupling 104, and a square groove 104b is symmetrically provided on the inner wall of the other end of the coupling 104.

[0034] Specifically, the operational status of the cables on the support assembly 100 can be preliminaryly determined through the inspection window 101b, and it can be determined whether or not inspection and repair work is necessary.

[0035] Preferably, the shape of the boss 104a fits with the shape of the connection groove 101d-2 of the output shaft 101d-1, and the shape of the square groove 104b fits with the shape of the square base 103a-1 of the lifting rod 103. By providing the coupling 104 between the output shaft 101d-1 and the threaded rod 103a, the torque output from the output shaft 101d-1 can be transmitted to the threaded rod 103a without loss. Subsequently, the rotation of the threaded rod 103a enables the lifting function of the lifting rod 103. By driving the threaded rod 103a with the drive motor 101d to rotate it in forward and reverse directions, the lightning protection connection base 201 can be raised and lowered.

[0036] Furthermore, the baffle plate 103b at the top of the lifting rod 103 limits the movement distance of the lightning protection connection base 201, preventing it from detaching from the lifting rod 103 due to operator error. At the same time, the buffer spring 103b-1 cushions the rising lightning protection connection base 201, preventing it from colliding with the baffle plate 103b and damaging the lightning rod 202 if its upward speed is too fast.

[0037] By providing the support assembly 100, the lightning protection connection base 201 can be fixed while the lifting function is realized, eliminating the need for workers to carry the lightning rod 202 to the top of the tower, and significantly improving safety.

[0038] Example 3 Referring to Figures 5 to 8, a third embodiment of the present invention is shown, which provides an easily replaceable lightning protection device for transmission towers, and this embodiment is based on the previous embodiment and differs from the previous embodiment in the following respects: A release groove 103d is provided in the track groove 103c, a release block 103d-1 is provided in the release groove 103d, a vertically positioned release spring 103d-2 is fixedly connected to the lower part of the release block 103d-1, and a lock block 103e is provided below the release groove 103d. A limiting groove 103f is further provided in 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 externally fitted to the limiting rod 103g, an inclined surface 103g-2 is provided at one end of the limiting rod 103g, and a projection block 103g-3 is symmetrically provided at the other end of the limiting rod 103g, the lightning protection connection base 201 includes a main plate 201a, side plates 201b are provided at both ends of the main plate 201a, connecting plates 201c are further provided on both side plates 201b, a connecting sleeve 201a-1 is provided on the outer wall of the main plate 201a, the lightning rod 202 is inserted into the connecting sleeve 201a-1, and a lifting sleeve 201a-2 is provided on the inner wall of the main plate 201a, and lifting sleeve A screw thread 201a-3 is provided on the inner wall of the section 201a-2, a lock groove 201d is provided on the inside of the side plate 201b, a lock hole 201d-1 is further provided at the bottom of the lock groove 201d, a lock pin 201e is provided inside the lock groove 201d, a lock column 201e-1 is provided at the bottom of the lock pin 201e that fits into the lock hole 201d-1, an expansion spring 201e-2 is fitted onto the lock column 201e-1, the inner diameter of the expansion spring 201e-2 is larger than the lock hole 201d-1, the lock column 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.

[0039] Specifically, the width of the track groove 103c matches the width of the lock pin 201e of the lightning protection connection base 201, and the lock pin 201e fitted into the track groove 103c restricts the lightning protection connection base 201, preventing it from falling off the lifting rod 103. At the same time, the lifting sleeve 201a-2 extends into the lifting rod 103 and can be externally fitted onto the threaded rod 103a, and the screwing of the threaded rod 103a with the threaded rod 201a-3 on the lifting sleeve 201a-2 enables the lifting and lowering of the lightning protection connection base 201.

[0040] Preferably, the inclination angles of the inclined surfaces of the lock pin 201e, the unlock block 103d-1, and the lock block 103e are the same, the inclined surfaces of the lock block 103e and the unlock block 103d-1 are arranged facing in opposite directions, and the force required to compress the unlock spring 103d-2 is smaller than the force required to compress the expansion spring 201e-2. Therefore, when the lock pin 201e applies pressure to the unlock block 103d-1, the unlock spring 103d-2 is compressed first, causing the unlock block 103d-1 to descend, and once the unlock spring 103d-2 is fully compressed, the expansion spring 201e-2 is compressed as pressure continues to be applied.

[0041] Furthermore, by fitting the projection block 103g-3 of the limiting rod 103g into the positioning groove 201c-2, it is ensured that the limiting rod 103g does not rotate during the movement process, and the inclined surface 103g-2 can always be positioned facing outwards from the raceway groove 103c.

[0042] In this embodiment, it is first necessary to transport the lightning rod 202 to the top of the lifting rod 103. At this time, it is only necessary to drive the drive motor 101d, and the torque output from the drive motor 101d is transmitted to the threaded rod 103a via the output shaft 101d-1, and the forward rotation of the threaded rod 103a drives the lightning connection base 201 up, and when the lightning connection base 201 has risen to the point where the lock pin 201e contacts the lock block 103e, the lightning connection base 201 As the height continues to rise, the expansion spring 201e-2 is continuously compressed, pushing the lock pin 201e further into the lock groove 201d. After the lock pin 201e is fully pushed into the lock groove 201d and moves above the lock block 103e, the lock pin 201e is released again by the action of the expansion spring 201e-2. The lower surface of the lock pin 201e and the upper surface of the lock block 103e engage, fixing the lightning protection connection base 201 and completing the installation of the lightning rod 202.

[0043] Preferably, in the process in which the lock pin 201e moves above the lock block 103e and pops out again, when the lock pin 201e pushes the limiting rod 103g back into the limiting groove 103f, the other end of the limiting rod 103g passes through the side wall of the track groove 103c and is inserted into the straight groove 201c-1 of the connecting plate 201c, thereby completing the secondary fixing of the lightning rod 202 and ensuring the stability of the mounting of the lightning rod 202.

[0044] When inspecting, repairing, or replacing the lightning rod 202, first keep the drive motor 101d in the forward direction. This causes the lightning connection base 201 to move upward by a certain distance, driven by the threaded rod 103a. During this movement, the lock pin 201e is continuously pushed back into the lock groove 201d by the pressure of the release block 103d-1. After the lock pin 201e is fully pushed into the lock groove 201d and moves above the release block 103d-1, reverse the drive motor 101d. The reverse rotation of the threaded rod 103a causes the lightning connection base 201 to begin descending. As the lock release spring 103d-2 is compressed more easily than the expansion spring 201e-2, the lock pin 201e moves downward. First, the unlock block 103d-1 is driven downward and moved until the unlock spring 103d-2 can no longer be compressed. Then, the downward movement of the lock pin 201e causes the expansion spring 201e-2 to begin to compress, pushing the lock pin 201e back into the lock groove 201d. In this way, the lock pin 201e can descend directly below the lock block 103e and then pop out. At this point, the lightning rod connection base 201 is unlocked, and by reversing the threaded rod 103a, the lightning rod connection base 201 can be directly driven down to the bottom of the lifting rod 103. This allows the worker to directly inspect and repair the lightning rod 202 from the ground, significantly improving inspection and repair efficiency.

[0045] By providing the removal assembly 200, the installation and removal of the lightning rod 202 can be completed simply by moving the lightning rod connection base 201 up and down on the lifting rod 103, significantly improving the efficiency of replacing the lightning rod 202. Furthermore, the operator only needs to control the forward and reverse rotation of the drive motor 101d throughout the entire process, making operation convenient and reducing safety hazards.
