Technical Field

[0001] The utility model relates to the technical field of sand prevention, in particular to a sand prevention device for a wind turbine. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean and pollution-free renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. Wind is one of the pollution-free energy sources. Moreover, it is inexhaustible. For coastal islands, grassland pastoral areas, mountainous areas and plateau areas that are short of water, fuel and have inconvenient transportation, it is very suitable to use wind power generation according to local conditions, and there is a lot of potential. Offshore wind power is an important field for the development of renewable energy, an important force to promote the advancement of wind power technology and industrial upgrading, and an important measure to promote the adjustment of energy structure. Offshore wind energy resources are abundant, and accelerating the construction of offshore wind power projects is of great significance to promoting the control of atmospheric haze in coastal areas, adjusting energy structure and transforming the mode of economic development. The desert has open terrain and is rich in wind and solar energy resources, but it has not been used in the work of sand control and prevention, and has been wasted in vain.

[0003] In desert control, when building a large number of sand-proof tree planting pits, sand retaining walls and sand-fixing layers through transportation equipment, fuel needs to be transported over long distances, which increases the transportation cost and the cost of the project. In addition, when charging the transportation equipment in windy and sandy weather, sand and gravel are likely to enter the charging gun connection port and accumulate. For this reason, we proposed a sand-proof device for wind turbines. Utility Model Content

The paddle is continuously in contact with the air permeable plate to vibrate the air permeable plate, and the sand blocked in the holes of the air permeable plate by negative pressure is shaken off, thereby improving the gas circulation efficiency. The negative pressure generated by the rotation of the fan increases the air pressure in the placement box and causes the opening and closing plate to overcome the force of the spring and open, so that the sand on the socket of the charging gun is blown off from the bottom of the placement box.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 8 The utility model provides a technical solution: comprising a base 1, the top of the base 1 is fixedly connected with four support columns 2, the tops of the four support columns 2 are commonly fixedly connected with a battery 3, an anti-blocking component 4 is arranged on the back of the battery 3, a placement box 5 is arranged on the back of the battery 3, and a sand discharge component 7 is arranged on the bottom of the placement box 5; the anti-blocking component 4 comprises a shell 401, the front of the shell 401 is fixedly connected to one side of the back of the battery 3, one side of the shell 401 is fixedly connected with a breathable plate 402, and the top of the shell 401 is fixedly connected with A sleeve 403, the inner ring surface of the sleeve 403 is fixedly connected with a plurality of connecting rods 408 and the connecting rods 408 are distributed in a ring array, the other end of each connecting rod 408 is commonly fixedly connected with a driving motor 405, the output shaft end of the driving motor 405 is fixedly connected with a fan 406, the middle of the bottom of the fan 406 is fixedly connected with an extension shaft 407, the bottom of the extension shaft 407 is fixedly connected with a paddle 409, the top of the sleeve 403 is fixedly connected with a connecting pipe 404 and the other end of the connecting pipe 404 is connected to the placement box 5.

[0024] In this embodiment, Figure 2 , Figure 5 and Figure 6As shown, the sand discharge assembly 7 includes an extension tube 6, which is fixedly connected to the side surface of the placement box 5, and the bottom of the extension tube 6 is fixedly connected to two protrusions 701, and a fixing rod 702 is fixedly connected between the two protrusions 701. A spring 705 is movably sleeved in the middle of the side surface of the fixing rod 702, and two fixing plates 703 are movably sleeved on the side surface of the fixing rod 702. The top of the fixing plate 703 is fixedly connected to an opening and closing plate 704, and the bottom of the opening and closing plate 704 is in contact with the pin of the spring 705. When the charging gun is used each time After the charging gun is clamped on the clamp arm 12, the sealing cover 8 is closed and the driving motor 405 is started so that the output shaft end of the driving motor 405 rotates and drives the fan 406 to rotate to generate negative pressure. When the fan 406 rotates, it rotates together with the extension shaft 407 and the paddle 409, and the paddle 409 contacts the air permeable plate 402 to vibrate and fall the gravel attached to the holes of the air permeable plate 402. As the internal pressure of the placement box 5 increases, the two opening and closing plates 704 overcome the force of the spring 705 and move around the fixed rod 702 as the center. The opening and closing plate 704 rotates, so that the gravel attached to the charging gun socket falls through the gap opened by the opening and closing plate 704 after being blown off. When the driving motor 405 is turned off, the fan 406 stops rotating. At this time, the pressure in the placement box 5 is balanced with the pressure of the external environment, and the opening and closing plate 704 seals the bottom of the extension tube 6 under the force of the spring 705, so that the inside of the placement box 5 is isolated from the external environment, so that the wind and sand cannot enter the placement box 5. After the construction is completed, the device is left in place to provide kinetic energy in the subsequent water supply operation. By tilting The placed air permeable plate 402 ensures that the sand will not be obstructed when falling, effectively preventing the sand from accumulating. The paddle 409 continuously contacts the air permeable plate 402 to vibrate the air permeable plate 402, thereby shaking off the sand blocked in the holes of the air permeable plate 402 by negative pressure, thereby improving the gas circulation efficiency. The negative pressure generated by the rotation of the fan 406 increases the air pressure in the placement box 5 and enables the opening and closing plate 704 to overcome the force of the spring 705 and open, so that the sand on the socket on the charging gun is blown off from the bottom of the placement box 5.

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, the back of the storage box 5 is connected to a sealing cover 8 through a hinged connection, and the back of the sealing cover 8 is fixedly connected to a handle 9.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 8 As shown, a plurality of circular grooves 10 are formed on the edge of the front side of the sealing cover 8 , and magnets 11 are fixedly sleeved inside the circular grooves 10 .

[0027] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, two clamping arms 12 are fixedly connected to the inner wall of one side of the placement box 5 close to the battery 3. The two tilted clamping arms 12 allow the wind force generated by the rotation of the fan 406 to blow on the charging gun muzzle at a certain angle, making it easier for the gravel to be discharged from the socket of the charging gun.

[0028] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, two wind turbines 13 are fixedly connected to the top of the base 1 .

[0029] The use method and advantages of the utility model: When the sand-proof device of the wind turbine is used, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, after the charging gun is clamped on the clamp arm 12 after each use, the sealing cover 8 is closed and the driving motor 405 is started so that the output shaft end of the driving motor 405 rotates and drives the fan 406 to rotate to generate negative pressure. When the fan 406 rotates, the extension shaft 407 and the paddle 409 rotate together, and the paddle 409 contacts the air permeable plate 402 to vibrate and fall the gravel attached to the holes of the air permeable plate 402. As the internal pressure of the placement box 5 increases, the two opening and closing plates 704 overcome the force of the spring 705 to fix The rod 702 rotates with the center of the circle, so that the gravel attached to the charging gun socket falls through the gap opened by the opening and closing plate 704 after being blown off. When the driving motor 405 is turned off, the fan 406 stops rotating. At this time, the pressure in the placement box 5 is balanced with the pressure of the external environment, and the opening and closing plate 704 seals the bottom of the extension tube 6 under the action of the spring 705, so that the inside of the placement box 5 is isolated from the external environment, so that the wind and sand cannot enter the placement box 5, and the device is left in place after the construction is completed to provide kinetic energy in the subsequent water supply operation.
