Description

Technical Field

[0001] This utility model belongs to the field of line protection technology, specifically a wind farm transmission line protection device. Background Technology

[0002] Wind farms are large-scale facilities that utilize wind energy to produce electricity. Their core function is to convert natural wind energy into electrical energy through wind turbine generators. They are an important part of the renewable energy generation field. During operation, wind farms need to transmit electricity through power lines. These transmission lines are usually equipped with protective sleeves to prevent damage or malfunctions caused by external factors (such as mechanical damage, environmental erosion, animal bites, etc.), thereby ensuring the safe and stable operation of the lines.

[0003] Utility model patent application publication number 202321835503.1 discloses a line protection device, relating to the field of line protection sleeve technology. It includes an installation protective sleeve and a fixing structure. An insert protective sleeve is installed at the opening of the installation protective sleeve. Both the installation and insert protective sleeves have fixing structures on their surfaces. The opening of the installation protective sleeve has a disassembly structure. The fixing structure includes an installation hole and an arc-shaped sponge pad. A line is slidably compressed onto the inner wall of the arc-shaped sponge pad. Both the installation and insert protective sleeves have installation holes. A threaded rod is rotatably connected to the inner wall of the installation hole. A limit block is threadedly connected to the surface of the threaded rod. A connecting slide is fixedly connected to the bottom of the threaded rod. A circular groove is formed on the bottom surface of the connecting slide. This invention solves the problem that existing line protection sleeves cannot be adjusted and fixed to adapt to lines of different thicknesses, which is detrimental to their proper use.

[0004] As can be seen from the aforementioned patent, there is a wind farm transmission line protection device, but it still has shortcomings in actual use. The most obvious one is that the current method usually adjusts the device by rotating the threaded rod to drive the arc-shaped sponge pad. However, the threaded rod is usually directly exposed to the working environment. When the working environment is humid or corrosive, the surface of the threaded rod is easily oxidized and corroded, which may even lead to the risk of breakage. This affects the stability of the threaded rod and reduces the protection effect on the line. Therefore, we propose a wind farm transmission line protection device. Utility Model Content

[0005] The purpose of this invention is to provide a wind farm transmission line protection device to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] Specifically, this application is as follows: a wind farm transmission line protection device includes: a first protective sleeve, a second protective sleeve, and mounting posts respectively fixedly connected to the outside of the first protective sleeve and the second protective sleeve. The first protective sleeve is hinged to one side of the second protective sleeve, and the second protective sleeve is provided with mounting parts for connecting the first protective sleeve.

[0008] One end of the mounting post has a square groove, and a sliding rod is slidably connected to the inner cavity of the square groove. One end of the sliding rod has a threaded hole, and the other end of the sliding rod is fixedly connected to a rubber pad. An arc-shaped limiting plate is fixedly connected to the side wall of the rubber pad. One end of the mounting post is rotatably connected to a knob, and a screw is fixedly connected to the side of the knob near the sliding rod. The screw is threaded into the inner cavity of the threaded hole.

[0009] As a preferred technical solution of this application, the mounting component includes a mounting plate, which is fixedly connected to one side of the first protective sleeve. The other side of the second protective sleeve is provided with a mounting groove that matches the mounting plate, and the second protective sleeve is provided with a positioning component for limiting the position of the mounting plate.

[0010] As a preferred technical solution of this application, the positioning component includes two sets of positioning cylinders, which are fixedly connected to both ends of the side wall of the second protective sleeve. The inner cavity of the positioning cylinder is slidably connected to a positioning rod. The side wall of the mounting plate and the inner side wall of the mounting groove are both provided with positioning holes that match the positioning rods. The positioning cylinder is provided with an elastic element for applying a thrust to the positioning rod.

[0011] As a preferred technical solution of this application, the elastic element includes a spring, a support ring is fixedly connected to the side wall of the positioning rod, the support ring is slidably connected to the inner cavity of the positioning cylinder, and the spring is fixedly connected between the side wall of the support ring and the inner side wall of the positioning cylinder.

[0012] As a preferred technical solution of this application, the end of the positioning rod away from the second protective sleeve passes through the inner wall of the positioning cylinder and is rotatably connected to a rotating block.

[0013] As a preferred technical solution of this application, a plurality of rubber strips are fixedly connected to one side of the arc-shaped limiting plate.

[0014] As a preferred technical solution of this application, the cross-section of the rotating block is rectangular.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In the scheme of this application:

[0017] 1. By setting mounting posts on both sides of the first and second protective sleeves, the mounting posts slide to support the sliding rod through square grooves. A knob is set at one end of the mounting post, which drives the screw to rotate. Since the screw is threaded to the sliding rod through a threaded hole, the rotation of the knob can drive the sliding rod and the arc-shaped limiting plate to move longitudinally. The arc-shaped limiting plate clamps and protects the line. By setting the screw inside the mounting post and isolating the screw from the external environment through the knob, the occurrence of oxidation and corrosion of the screw is reduced, ensuring the stability of the threaded rod and improving the protection effect of the line.

[0018] 2. By setting an mounting plate on one side of the first protective sleeve and placing the mounting plate in the mounting groove on the second protective sleeve, the mounting plate is fixed in the mounting groove by a limiting positioning rod in conjunction with a positioning hole, thus fixing the first and second protective sleeves. When disassembling, by rotating the rotating block, the rotating block lifts the positioning rod, realizing the translation of the positioning rod and causing the spring to deform. At this time, the positioning rod moves out of the positioning hole, so that the mounting plate and the mounting groove are no longer limited, thus facilitating the disassembly and assembly of the first and second protective sleeves and making it convenient to use.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 A wind farm transmission line protection device includes: a first protective sleeve 100, a second protective sleeve 120, and mounting posts 200 fixedly connected to the outer sides of the first protective sleeve 100 and the second protective sleeve 120, respectively. The first protective sleeve 100, in conjunction with the second protective sleeve 120, provides isolation protection for the transmission line. The first protective sleeve 100 is hinged to one side of the second protective sleeve 120, and the second protective sleeve 120 is provided with mounting parts for connecting the first protective sleeve 100. One end of the mounting post 200 has a square groove 210, and a sliding rod 220 is slidably connected to the inner cavity of the square groove 210. The mounting post 200 supports the sliding rod 220 through the square groove 210. One end of the sliding rod 220 has a threaded hole 221, and the other end of the sliding rod 220 is fixedly connected to a rubber pad 230. An arc-shaped limiting plate 240 is fixedly connected to the side wall of the rubber pad 230. A knob 250 is rotatably connected to one end of the mounting post 200. A screw 260 is fixedly connected to the side of the knob 250 near the sliding rod 220. The screw 260 is threaded into the inner cavity of the threaded hole 221. The knob 250 drives the screw 260 to rotate. At this time, the screw 260 is threaded into the threaded hole 221, while the sliding rod 220 slides in the square groove 210 and cannot rotate. This allows the screw 260 to drive the sliding rod 220 to move longitudinally when it rotates. The sliding rod 220 drives the rubber pad 230 and the arc-shaped limiting plate 240 to move longitudinally. The rubber pad 230 creates an elastic force between the sliding rod 220 and the arc-shaped limiting plate 240, and the arc-shaped limiting plate 240 clamps and protects the circuit.

[0029] Please see Figure 1-3The mounting component includes a mounting plate 110, which is fixedly connected to one side of the first protective sleeve 100. The other side of the second protective sleeve 120 is provided with a mounting groove 130 that matches the mounting plate 110. The second protective sleeve 120 is provided with a positioning element for limiting the mounting plate 110. By placing the mounting plate 110 in the mounting groove 130 and limiting the mounting plate 110 by the positioning element, the installation of the first protective sleeve 100 and the second protective sleeve 120 is realized.

[0030] Please see Figure 1-3 The positioning component includes two sets of positioning cylinders 140, which are fixedly connected to both ends of the side wall of the second protective sleeve 120. The inner cavity of the positioning cylinder 140 is slidably connected to a positioning rod 150. The side wall of the mounting plate 110 and the inner side wall of the mounting groove 130 are provided with positioning holes that match the positioning rod 150. The positioning cylinder 140 is provided with an elastic element for applying a pushing force to the positioning rod 150. The positioning cylinder 140 supports the positioning rod 150, and the positioning rod 150 limits the mounting plate 110 in the mounting groove 130 through the positioning hole.

[0031] Please see Figure 1-3 The elastic element includes a spring 152. A support ring 151 is fixedly connected to the side wall of the positioning rod 150. The support ring 151 is slidably connected to the inner cavity of the positioning cylinder 140. The spring 152 is fixedly connected between the side wall of the support ring 151 and the inner side wall of the positioning cylinder 140. The spring 152 and the support ring 151 work together to apply an elastic force to the positioning rod 150, so that the positioning rod 150 can limit the mounting plate 110 through the positioning hole.

[0032] Please see Figure 1-3 The end of the positioning rod 150 away from the second protective sleeve 120 passes through the inner wall of the positioning cylinder 140 and is rotatably connected to the rotating block 160. The rotating block 160 is designed so that it can hold the positioning cylinder 140 when it rotates. Since the cross-section of the rotating block 160 is rectangular, it can pull the positioning rod 150 to move, so that the positioning rod 150 moves out of the positioning hole.

[0033] Please see Figure 1 and Figure 4 Multiple sets of rubber strips 241 are fixedly connected to one side of the arc-shaped limiting plate 240. By setting the rubber strips 241, the arc-shaped limiting plate 240 avoids hard contact when clamping the circuit, thereby achieving the function of protecting the circuit.

[0034] Please see Figure 1-3 The rotating block 160 has a rectangular cross-section, which allows the rotating block 160 to pull the positioning rod 150 to move, so that the positioning rod 150 moves out of the positioning hole.

[0035] Specifically, when using this device, the first protective sleeve 100 is opened, and the circuit is placed between the two sets of arc-shaped limiting plates 240. Then, the first protective sleeve 100 is closed, and the first protective sleeve 100 moves the mounting plate 110 into the mounting groove 130 on the second protective sleeve 120. Then, by rotating the rotating block 160, the spring 152 applies an elastic force to the support ring 151, and the support ring 151 pushes the positioning rod 150 into the positioning hole on the mounting plate 110. Then, the knob 250 is rotated, and the knob 250 drives the screw 260 to rotate. The rotation of the screw 260 drives the sliding rod 220 to move longitudinally. The sliding rod 220 drives the arc-shaped limiting plate 240 to move through the rubber pad 230. The arc-shaped limiting plate 240 contacts the circuit through the rubber strip 241 and clamps and protects the circuit, thus completing the use of the device.
