Description

Technical Field

[0001] This utility model belongs to the field of power tower technology, and in particular relates to a protective device for power towers. Background Technology

[0002] The protective devices used on power towers mainly include fall protection and lightning protection. Among these, lightning rods are one of the main facilities for lightning protection in power systems. They are usually installed at the top of the power tower as devices to guide lightning current into the ground, protecting overhead transmission lines, towers, and equipment from direct lightning strikes. They work on the principle of point discharge. During thunderstorms, when charged clouds appear in the sky, the lightning rod senses the charge and neutralizes it through tip discharge, preventing the charge from accumulating to a level that could cause a lightning strike. In this way, the lightning rod effectively guides lightning to the ground, protecting the power tower and surrounding equipment. Lightning rods play a crucial role in lightning protection for power towers and are an indispensable protective device. A problem with existing technology is that current lightning rods are usually installed and fixed to the tower body using multiple bolts. This requires repeated tightening and loosening of bolts with tools during installation and subsequent maintenance and replacement, which is not only time-consuming and labor-intensive but also affects the efficiency of disassembly and assembly work during maintenance and replacement.

[0018] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 5 As shown in the figure, a protective device for power towers provided by this utility model includes a tower body 1, a lightning rod 2, a connecting end 3, and a mounting plate 4. The lightning rod 2 is located at the top of the tower body 1 and is movably connected to the tower body 1. The connecting end 3 is located at the lower rear side of the lightning rod 2 and is fixedly connected to the lightning rod 2. The mounting plate 4 is fixedly connected to the lower end of the lightning rod 2. A fixing device 5 is provided below the lightning rod 2 and is fixedly connected to the tower body 1. The lightning rod 2 is movably connected to the tower body 1 through the fixing device 5.

[0021] refer to Figure 1 , Figure 2 and Figure 3 The fixing device 5 includes a box 51, a self-locking component 52, a linkage component 53, and a control component 54. The box 51 is located below the mounting plate 4 and is fixedly connected to the tower body 1. There are four self-locking components 52, which are respectively located around the upper part of the box 51. The linkage component 53 is located at the lower end of the four self-locking components 52. The control component 54 is located on the lower right side of the linkage component 53.

[0022] The above solution involves setting up a fixing device 5 to secure the lightning rod 2, which facilitates the quick installation and disassembly of the lightning rod 2 during installation and subsequent maintenance, thereby improving the efficiency of the disassembly and assembly work during the maintenance of the lightning rod 2.

[0023] refer to Figure 2 , Figure 3 and Figure 4 The self-locking assembly 52 includes positioning rods 521, lock heads 522, push springs 523, pressure shafts 524, and sealing plates 525. There are two positioning rods 521, which are respectively located on the left and right sides of the front end inside the box body 51, and their front ends are fixedly connected to the front surface inside the box body 51. The lock heads 522 are sleeved on the surfaces of the two positioning rods 521 and are slidably connected to the positioning rods 521. The upper end of the lock heads 522 extends out of the box body 51 and is movably connected to the box body 51. There are two push springs 523, which are respectively sleeved on the surfaces of the two positioning rods 521, and their front and rear ends are fixedly connected to the front surface inside the box body 51 and the lower front end of the lock heads 522, respectively. The sealing plates 525 are sleeved on the upper end of the lock heads 522 and are fixedly connected to the lock heads 522. The sealing plates 525 are in contact with and movably connected to the upper surface of the box body 51.

[0024] The above solution involves setting a self-locking component 52 to cooperate with the mounting plate 4 and snap it into place, thereby achieving quick fixation during installation and improving installation efficiency.

[0025] refer to Figure 3 , Figure 4 and Figure 5 The linkage component 53 includes a rotating shaft 531, a turntable 532, a travel groove 533, and a gear 534. The rotating shaft 531 is disposed inside the housing 51, and its upper and lower ends are rotatably connected to the upper and lower ends inside the housing 51, respectively. The turntable 532 is fitted onto the surface of the rotating shaft 531 and is fixedly connected to the rotating shaft 531. There are four travel grooves 533, which are evenly distributed around the upper surface of the turntable 532 and all penetrate the turntable 532. The lower ends of the four pressure shafts 524 extend into the four travel grooves 533 and are movably connected to the travel grooves 533. The gear 534 is fitted onto the lower surface of the rotating shaft 531 and is fixedly connected to the rotating shaft 531.

[0026] The above scheme is adopted: by setting up a linkage component 53 to drive the self-locking component 52, the four self-locking components 52 are driven synchronously at the same time.

[0027] refer to Figure 3 and Figure 5 The control component 54 includes a slide rail 541, a rack 542, and a pressing member 543. The slide rail 541 is located on the right side of the gear 534 and is fixedly connected to the lower inner surface of the box 51. The rack 542 is sleeved on the surface of the slide rail 541 and is slidably connected to the slide rail 541. The rack 542 is meshed with the gear 534. The pressing member 543 is fixedly connected to the right side of the front end of the rack 542, and the front end extends out of the box 51 and is movably connected to the box 51.

[0028] The above solution is adopted: by setting up a control component 54, it is used to drive and control the fixing device 5. During disassembly, it drives the linkage component 53 to simultaneously control the opening and closing of the four self-locking components 52, thereby releasing the snap-fit ​​fixing of the mounting plate 4.

[0029] refer to Figure 1 and Figure 2 The mounting plate 4 has positioning holes 6 at the four corners of its lower surface. All four positioning holes 6 pass through the mounting plate 4. Limiting rods 7 are fixedly connected at the four corners of the upper surface of the box 51. The positions of the four limiting rods 7 and the four positioning holes 6 correspond to each other and are compatible.

[0030] The above solution is adopted: positioning holes 6 are provided at the four corners of the lower surface of the mounting plate 4, which are used to cooperate with the limiting rods 7 set at the four corners of the upper surface of the box 51 to limit the mounting plate 4 and ensure the stability of the lightning rod 2 installation.

[0031] refer to Figure 3 and Figure 4 Limiting plates 8 are provided at the rear ends of the two positioning rods 521, and the limiting plates 8 are fixedly connected to the positioning rods 521.

[0032] The above solution is adopted: by setting a limit plate 8 at the rear end of the positioning rod 521, the movement distance of the lock head 522 is limited, so as to prevent the lock head 522 from disengaging from the positioning rod 521.

[0033] The working principle of this utility model:

[0034] During installation, align the four positioning holes 6 with the four limiting rods 7 on the housing 51, and press the mounting plate 4 downwards so that the limiting rods 7 are inserted into the positioning holes 6. As the mounting plate 4 is pressed downwards, it will compress the four lock heads 522, causing them to move outwards from the surface of the positioning rods 521. Simultaneously, this movement compresses the push spring 523. After the mounting plate 4 is fully pressed down, it will no longer compress the lock heads 522. At this point, the push spring 523 will rebound, pushing the lock heads 522 inwards from the housing 51, engaging the mounting plate 4, and securing the lightning rod 2. Simultaneously, the sealing plate 525 will move along with the lock heads 522, tightly sealing against the surface of the housing 51. The adhesive provides a certain degree of sealing. During subsequent disassembly, pressing the pressing part 543 backward pushes the rack 542 to move backward on the surface of the slide rail 541. As the rack 542 moves backward, it drives the gear 534 meshing with it to rotate. The rotation of the gear 534 drives the rotating shaft 531 to rotate. The rotation of the rotating shaft 531 drives the turntable 532 to rotate. The rotation of the turntable 532 drives the four stroke grooves 533 to rotate. As the four stroke grooves 533 rotate, they squeeze the four internal pressure shafts 524. The pressure on the pressure shafts 524 causes the lock head 522 to move outward from the surface of the positioning rod 521 towards the outside of the box 51 to release the fixation. Then, the lightning rod 2 can be pulled upward to remove it.

[0035] In summary, this protective device for power towers, through the coordinated use of the tower body 1, lightning rod 2, connecting end 3, mounting plate 4, fixing device 5, box 51, self-locking component 52, positioning rod 521, lock head 522, push spring 523, pressure shaft 524, sealing plate 525, linkage component 53, rotating shaft 531, turntable 532, stroke groove 533, gear 534, control component 54, slide rail 542, rack 542, pressing component 543, positioning hole 6, limit rod 7, and limit plate 8, solves the problem that existing lightning rods typically use multiple bolts to install and fix them to the tower body. This requires repeated tightening of bolts with tools during installation and subsequent maintenance and replacement, which is not only time-consuming and labor-intensive but also affects the efficiency of disassembly and assembly work during maintenance and replacement.
