Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting and rust removal, specifically to a sandblasting and rust removal device for the outer surface of a wind turbine. Background Technology

[0002] A wind turbine, also known as a wind engine or wind power machine, is a device that converts air kinetic energy into mechanical energy and generates electricity through a generator. It mainly consists of components such as blades, towers, nacelles, and control systems. It is used in wind power plants and distributed energy systems. During the production process, the outer surface of the wind turbine needs to be sandblasted to remove rust, thereby increasing its service life.

[0003] For example, Chinese utility model patent CN110653726A discloses a rust removal and sandblasting device for ship hulls. This device includes a sand storage tank with supporting legs around its bottom. A sand outlet pipe is located at the bottom of the tank, and a high-pressure air duct is connected to the outlet pipe. One end of the high-pressure air duct is connected to a sandblasting hose, with a sandblasting nozzle attached to its end. The other end of the high-pressure air duct is connected to a double-ended air inlet pipe. One end of the double-ended air inlet pipe is connected to the high-pressure air duct, and the other end is connected to the internal space of the sand storage tank. A high-pressure main air duct is connected to the middle of the double-ended air inlet pipe. This invention can be manufactured using simple tools and materials found in factories, eliminating the need for large-scale rust removal equipment. It is simple to operate, flexible, and convenient, especially effective and efficient for small ship hulls, demonstrating significant practical value.

[0004] The existing sandblasting and rust removal equipment generally uses long sandblasting hoses, which are not convenient for quick retrieval and collection, thus making it inconvenient to transport the equipment and also inconvenient to adjust the length to meet different needs. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sandblasting and rust removal device for the outer surface of a wind turbine, which facilitates the stretching of the sandblasting pipe to different lengths during use, thereby facilitating the rapid collection of the sandblasting pipe and making the overall device easy to transport, thus improving its practicality.

[0006] This utility model discloses a sandblasting and rust removal device for the outer surface of a wind turbine. It includes a sandblasting machine body, a support fixedly installed at the bottom of the outer wall of the machine body, a sandblasting pipe connected to the output end of the machine body, a nozzle connected to the output end of the sandblasting pipe, a fixed plate fixedly installed on the outer wall of the nozzle, and a collection mechanism rotatably installed at the top of the support via a rotating mechanism for collecting the sandblasting pipe. The collection mechanism includes a rotating plate, a connecting plate fixedly installed at the top of the rotating plate, the connecting plate being in contact with the outer wall of the sandblasting machine body, and a fixed plate fixedly installed at the top of the support, located outside the connecting plate and rotatably connected to the rotating plate. The sandblasting pipe is located between the fixed plate and the connecting plate. A fixing groove is formed at the top of the fixed plate, and two upright plates are symmetrically fixedly installed on the outer wall of the fixing groove. Two rotating rollers are rotatably installed on the two upright plates, and the sandblasting pipe is located between the two rotating rollers. The wind turbine's external surface sandblasting and rust removal device uses a fixed plate and a connecting plate to clamp the sandblasting pipe, allowing for collection when not in use. When the sandblasting pipe needs to be used, it is passed through a fixed groove on the fixed plate and stretched under the control of two rotating rollers. Simultaneously, the connecting plate and rotating plate rotate with the help of a rotating mechanism, facilitating the lengthening of the sandblasting pipe to suit different needs. When collecting the sandblasting pipe, rotating the connecting plate returns it to its initial state. This allows for quick collection of the sandblasting pipe and facilitates the overall transport of the device, improving its practicality.

[0007] Preferably, the rotating mechanism includes multiple rotating blocks, each of which is symmetrically fixedly installed at the bottom of the rotating plate. The top of the support is provided with an annular groove, and each rotating block is rotatably connected to the annular groove. When the sandblasting pipe rotates between the gap inside the fixed plate and the connecting plate, it synchronously drives the rotating blocks to rotate inside the annular groove, thereby facilitating the stretching of the sandblasting pipe.

[0008] Preferably, a sealing plate is fixedly installed on the outer side wall of the fixed plate, and the inner side wall of the sealing plate is rotatably connected to the outer side wall of the support. By installing the sealing plate, it is convenient to seal the gap between the annular slide and the rotating block, so as to prevent dust and impurities from entering the interior of the annular slide.

[0009] Preferably, multiple support columns are fixedly installed around the bottom of the sandblasting machine body, and a fixed seat is fixedly installed between two adjacent support columns. Both ends of the fixed seat are rotatably mounted with wheels via a rotating shaft. When not in use, the outer side of the wheel is located on the upper side of the bottom of each support column. When the device needs to be moved, the device is tilted and the wheels contact the ground, thus facilitating the movement of the device.

[0010] Preferably, multiple brackets are fixedly installed on the top of the fixed plate, and each bracket is in contact with the outer side wall of the connecting plate. By having multiple brackets in contact with the connecting plate, it is easier to effectively limit the operation of the rotating connecting plate.

[0011] Preferably, a limiting plate is fixedly installed at the top of one of the vertical plates, and a connecting roller is rotatably installed at the bottom of the limiting plate. The connecting roller is in contact with the outer wall of the sandblasting pipe. Before the sandblasting pipe passes through the two rotating rollers, it contacts the connecting roller, which facilitates the guiding operation of the sandblasting pipe.

[0012] Preferably, each of the rotating rollers has a connecting groove on its outer side wall. The connecting groove facilitates the limiting operation of the outer side wall of the sandblasting pipe.

[0013] Preferably, the outer wall of the fixing plate is provided with multiple through holes, which facilitates the observation of the storage length of the sandblasting pipe between the fixing plate and the connecting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This sandblasting and rust removal device for the outer surface of the wind turbine uses a fixing plate and a connecting plate to clamp the sandblasting pipe, thereby collecting the sandblasting pipe when not in use. When the sandblasting pipe needs to be used, it is passed through the fixing groove on the fixing plate and stretched under the limit of two rotating rollers. When the sandblasting pipe is stretched, the connecting plate and the rotating plate are simultaneously rotated in cooperation with the rotating mechanism, which facilitates the lengthening of the sandblasting pipe. The length of the sandblasting pipe can be adjusted according to different needs. When the sandblasting pipe needs to be collected, the connecting plate is rotated to restore the sandblasting pipe to its initial state. This facilitates the stretching of the sandblasting pipe to different lengths when in use, and facilitates the rapid collection of the sandblasting pipe. This makes the entire device easier to transport and improves its practicality. Attached Figure Description
