Description

Technical Field

[0001] The present invention relates to the technical field of line lightning protection, and particularly relates to a multi-angle air-blowing lightning protection device for a wind farm collector line. Background Art

[0002] The collector line is one of the very important components in a wind farm. It is responsible for efficiently transmitting the electric energy of multiple wind turbines to a substation for further feeding into the power grid. The collector line usually consists of multiple cables, and its length is determined by the scale of the wind farm. The collector line of a wind farm is generally located in mountainous or low mountain and hilly areas, and its 35 kV collector line can adopt two transmission forms: overhead lines or directly buried cables.

[0003] Lightning arresters are usually used for lightning protection in the collector line of a wind farm. Due to the complex natural environment, terrain, mountains, and vegetation in the wind farm, fallen leaves and other impurities and dust are likely to fall on the main body of the lightning arrester, which is not convenient for cleaning and affects its normal operation. Therefore, we designed a multi-angle air-blowing lightning protection device for a wind farm collector line. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose a multi-angle air-blowing lightning protection device for a wind farm collector line.

[0007] As a further solution of the present invention, two guide rods are fixed to the inner wall of the notch, and guide holes for the guide rods to pass through are formed in the first connecting rod.

The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0017] Referring to Figures 1-5 , a lightning protection device for a multi-angle blast-type wind farm collector line, including a mounting frame 1. One side of the top of the mounting frame 1 is fixedly provided with a lightning arrester main body 2. A notch 3 is opened at a position on the top of the mounting frame 1 away from the lightning arrester main body 2. A blast mechanism 6 is installed at the position of the notch 3. An electric telescopic rod 171 for realizing the angle adjustment of the blast mechanism 6 is installed at the bottom of the mounting frame 1; The blast mechanism 6 includes an air outlet cover 9. One side of the air outlet cover 9 facing the lightning arrester main body 2 is provided on three sides, and both the upper and lower surfaces are symmetrically inclined. A mounting back plate 10 is fixedly provided on the back of the air outlet cover 9, and an integrated fan 11 is fixedly installed in the mounting back plate 10. A protective mesh cover is fixedly provided on the back of the mounting back plate 10; Cleaning mechanisms 7 are installed on both sides of the outer wall of the air outlet cover 9.

[0018] In this embodiment, both sides of the inner wall of the notch 3 are rotatably connected with mounting arms 12. The air outlet cover 9 is fixed between the two mounting arms 12. Both sides of the outer wall of the mounting back plate 10 are rotatably connected with support arms 13. The same U-shaped mounting block 16 is fixed between the two support arms 13 through a first connecting rod 14. An L-shaped frame 17 is fixedly provided at the bottom of the mounting frame 1. The electric telescopic rod 171 is fixed on the L-shaped frame 17. The output shaft of the electric telescopic rod 171 is rotatably connected with the U-shaped mounting block 16. The electric telescopic rod 171 pulls the U-shaped mounting block 16 rotatably connected thereto. Under the action of pulling the first connecting rod 14, the support arms 13 are deflected. Since the air outlet cover 9 itself is rotatably connected to the inner wall of the notch 3 through the mounting arms 12, when the support arms 13 are deflected, the whole blast mechanism 6 is deflected clockwise until it is perpendicular to the mounting frame 1. At this time, the integrated fan 11 performs the blast work, and the wind blows out from three sides of the air outlet cover 9 and blows against the outer wall of the lightning arrester main body 2.

[0019] In this embodiment, two guide rods 5 are fixedly provided on the inner wall of the notch 3. A guide hole 15 for the guide rod 5 to pass through is opened on the first connecting rod 14.

[0020] In this embodiment, the same second connecting rod 18 is fixed between the two mounting arms 12.

[0021] In this embodiment, the cleaning mechanism 7 includes a connector 22 rotatably arranged on the outer wall of the mounting arm 12. A water pipe 19 is fixed to the outer end of the connector 22. A plurality of spray nozzles 20 are equidistantly fixed on the water pipe 19. A hose 21 is fixed to the water inlet end of the water pipe 19. A through hole 4 for the hose 21 to pass through is formed in the mounting frame 1. An electric push rod 23 is fixed to the outer wall of the mounting arm 12. A rack 24 is fixed to the output shaft of the electric push rod 23. A toothed ring 25 is fixedly sleeved on the outer wall of the connector 22. The rack 24 meshes with the toothed ring 25. The spray nozzles 20 are installed on the outer wall of the mounting arm 12, and the spray nozzles 20 are connected to the hose 21. The hose 21 is connected and then connected to a water pump for water supply. Water is sprayed from the spray nozzles 20 to wash the outer wall of the lightning arrester body 2. At the same time, the electric push rod 23 works to move the rack 24 up and down, causing the toothed ring 25 to rotate reciprocally, and then the connector 22 drives the water pipe 19 to swing, achieving a better washing effect.

[0022] In this embodiment, a remote control cabinet 8 is fixed to the bottom of the mounting frame 1. A power supply and a remote controller are fixed in the remote control cabinet 8. The power supply is electrically connected to the remote controller. The remote controller is electrically connected to the integrated fan 11, the electric telescopic rod 171 and the electric push rod 23. The remote controller is connected to a remote control, for remotely controlling the equipment on the ground to work, which is convenient to operate.

[0023] Working principle: Since there are provided a mounting frame 1, a lightning arrester body 2, a blowing mechanism 6, etc., through the above structural design, the whole blowing mechanism 6 is close to the notch 3. When it is necessary to blow and clean the lightning arrester body 2, the electric telescopic rod 171 located at the bottom of the mounting frame 1 is started. The electric telescopic rod 171 pulls the U-shaped mounting block 16 rotatably connected thereto. The provided guide rod 5 passes through the guide hole 15 on the first connecting rod 14. Under the action of pulling the first connecting rod 14, the support arm 13 is deflected. Since the air outlet hood 9 itself is rotatably connected to the inner wall of the notch 3 through the mounting arm 12, when the support arm 13 is deflected, the whole blowing mechanism 6 is deflected clockwise until it is perpendicular to the mounting frame 1. At this time, the integrated fan 11 blows air. The air blows out from three sides of the air outlet hood 9 and blows against the outer wall of the lightning arrester body 2, effectively solving the problems raised in the background art, being able to blow and clean the impurities adhered to the outer wall of the lightning arrester body 2, and avoiding the impurities adhered to the outer wall of the lightning arrester body 2 from affecting its work.
