However, this method has the risk of damaging the paint on the surface of the car, and the cleaning speed is relatively slow. To solve the above problems, the Chinese patent with the announcement number of 204452394 discloses a hydraulically driven rotating cleaning brush, including a brush, a through hole is opened in the middle of the brush, the through hole is fixed and connected to a pipeline, a spiral blade is arranged inside the pipeline, the pipeline is rotatably connected to the shell, and the rear end of the shell is provided with an interface identical to the rear end of the pipeline. The interface is connected to the outlet of the water gun, and the water flow in the water gun must pass through the spiral blade after entering the interface. The spiral blade and the inner wall of the cylinder form a spiral water flow channel. Therefore, the energy of the water flow can make the spiral blade rotate, thereby driving the brush on the head to rotate together. The above cleaning brush can drive the spiral blade in the pipeline by hydraulic power while discharging water, and drive the pipeline to rotate, driving the cleaning brush connected to the pipeline to rotate, and realizing rotary cleaning. In the above structure, the spiral blade is arranged in the pipeline, the manufacturing process is relatively complicated, and the cost is high. At the same time, during the cleaning process, detergent cannot be added as needed. Summary of the invention
[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a hydraulically driven rotary cleaning brush to solve the problems that the existing cleaning brushes have a complex structure and cannot add detergent during the cleaning process.
[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

In this way, the water inlet pipe is connected to the external high-pressure water pipe. After the water valve of the high-pressure water pipe is opened, the high-pressure water in the high-pressure water pipe enters the brush body drive box through the water inlet pipe and is opposite to the blades of the impeller. The impeller rotates under the impact of the high-pressure water, and drives the rotating shaft fixed thereto to rotate together, and then drives the brush on the rotating shaft to rotate. At the same time, when the high-pressure water enters the brush body drive box, the high-pressure water fills the box body, and water is sprayed to the brush from the water spray port on the box body, so that the brush continues to have water to wet its bristles during the rotation process, and then rotates to clean the vehicle or other items. In addition, during the initial cleaning, cleaning products such as cleaning liquid or cleaning powder can be injected into the brush body drive box through the cleaning agent delivery nozzle. Under the stirring of the impeller, the liquid in the brush body drive box will be evenly stirred to form clean water with a certain cleaning effect. The brush is detachably connected to the end of the rotating shaft, so that it is convenient to replace the brush as needed.
[0006] Furthermore, the brushes are provided with two, the left and right ends of the rotating shaft are connected to the brush body of the brush by threads, two bearings are provided in the brush body driving box and are distributed on the left and right sides, the rotating shaft is sleeved on the bearings and is fixedly connected to the hub of the impeller. In this way, after two brushes are provided, the cleaning area is larger, and at the same time, the two ends of the rotating shaft are more stable; the provided bearings can make the rotating shaft rotate more smoothly.
[0007] Furthermore, the mouth of the water inlet pipe extends into the brush body drive box and is adjacent to the upper end of the impeller, and the water inlet pipe and the brush body drive box are integrally formed. In this way, after the water inlet pipe is inserted, it is closer to the blades of the impeller, and the impact force is greater. After the water inlet pipe and the brush body drive box are integrally formed, the sealing is good and it is not easy to leak.
[0008] Furthermore, a left water outlet pipe and a right water outlet pipe connected to the water inlet pipe are provided near the pipe opening, and the left water outlet pipe and the right water outlet pipe correspond to the bristles of the left and right brushes respectively; at least one nozzle is also provided at the lower end of the brush body driving box. In this way, after the left and right water outlet pipes are directly provided on the water inlet pipe, high-pressure water can be discharged more quickly, so that the bristles of the brushes are wetted more quickly. The nozzle provided at the lower end can form multiple water spraying points between the two brushes, and can directly flush the outer surface of the cleaned object during the mobile cleaning process, so as to achieve a better cleaning effect.
[0009] Furthermore, the brush is in a disc shape, and the brush body driving box is in a circular shape. In this way, the brush has bristles all around it, so that when the brush rotates continuously, the bristles can always contact the outer surface of the object to be cleaned.

[0015] like Figure 1-Figure 3As shown, the hydraulically driven rotary cleaning brush comprises a brush body driving box 1, a brush 5 connected to the brush body driving box 1 is arranged on the outside thereof, a water inlet pipe 11 for communicating with an external high-pressure water pipe is arranged on the brush body driving box 1, an impeller 2 with a plurality of blades 21 on the outside thereof is rotatably mounted in the brush body driving box 1 via a rotating shaft 3, the blades 21 of the impeller 2 correspond to the water inlet pipe 11, and the middle part of the impeller 2 is fixedly connected to the rotating shaft 3; the left and right ends or one end of the rotating shaft 3 extend out of the brush body driving box 1, and are detachably connected to the brush body 51 of the brush 5 ; A detergent delivery nozzle 13 is also provided on the brush body driving box 1 and beside the water inlet pipe 11, and a sealing cover 14 is provided on the detergent delivery nozzle 13; a plurality of water spraying ports 15 are provided on the side of the brush body driving box 1 facing the brush 5, and the water spraying ports 15 correspond to the bristles 52 of the brush 5; the lower end surface of the brush 5 is located below the brush body driving box 1 (thereby ensuring that the bristles 52 extend out of the lower end of the brush body driving box 1 and contact the outer surface of the vehicle to be cleaned); in order to facilitate the adjustment of water pressure according to needs, a pressure regulating valve for adjusting water pressure is provided on the water inlet pipe 11 or the external high-pressure water pipe. In this way, the water inlet pipe 11 is connected to the external high-pressure water pipe. After the water valve of the high-pressure water pipe is opened, the high-pressure water in the high-pressure water pipe enters the brush body driving box 1 through the water inlet pipe 11, and is opposite to the blades 21 of the impeller 2. The impeller 2 rotates under the impact of the high-pressure water, and drives the rotating shaft fixed thereto to rotate together, and then drives the brush 5 on the rotating shaft to rotate. At the same time, when the high-pressure water enters the brush body driving box 1, the high-pressure water fills the box, and water is sprayed from the water spray port 15 on the box to the brush 5, so that the brush 5 continues to have water to wet its bristles 52 during the rotation process, and then rotates to clean the vehicle or other objects. In addition, during the initial cleaning, cleaning liquid or cleaning powder and other cleaning supplies can be injected into the brush body driving box 1 through the cleaning agent delivery nozzle 13. Under the stirring of the impeller 2, the liquid in the brush body driving box 1 will be evenly stirred to form clean water with a certain cleaning effect. The brush 5 is detachably connected to the end of the rotating shaft, so that the brush 5 can be replaced as needed. When used, the water inlet pipe 11 can be used as a grip for cleaning personnel. A flexible sleeve is set on the water inlet pipe 11 for easy gripping.
[0016] like Figure 1 As shown, in this embodiment, two brushes 5 are provided, and the left and right ends of the rotating shaft are connected to the brush body 51 of the brush 5 by threads, and two bearings 4 distributed on the left and right are provided in the brush body driving box 1, and the rotating shaft is sleeved on the bearings 4 and fixedly connected to the hub of the impeller 2. In this way, after two brushes 5 are provided, the cleaning area is larger, and at the same time, the two ends of the rotating shaft are more stable; the provided bearings 4 can make the rotating shaft rotate more smoothly.
[0017] The rotating shaft 3 in this embodiment is a whole shaft. In a specific application, the rotating shaft 3 can be set as a left rotating shaft and a right rotating shaft. The left and right rotating shafts are respectively fixed to the center of the hub of the impeller 2 by a tight fit or a threaded fit, and the contact part between the rotating shaft and the brush body drive box is provided with a sealing ring for sealing.
[0018] Furthermore, the mouth of the water inlet pipe 11 extends into the brush body drive box 1 and is adjacent to the upper end of the impeller 2, and the water inlet pipe 11 and the brush body drive box 1 are integrally formed. In this way, after the water inlet pipe 11 is inserted, it is closer to the blades 21 of the impeller 2, and the impact force is greater. After the water inlet pipe 11 and the brush body drive box 1 are integrally formed, the sealing is good and it is not easy to leak.
[0019] Furthermore, a left water outlet pipe 12 and a right water outlet pipe connected to the water inlet pipe 11 are provided near the pipe mouth, and the left water outlet pipe 12 and the right water outlet pipe correspond to the bristles 52 of the brushes 5 on the left and right sides, respectively; at least one nozzle 16 is also provided at the lower end of the brush body driving box 1, and the water sprayed by the nozzle 16 can be in a columnar or mist shape, and the size of the nozzle 16 can be set according to needs. In this way, after the left and right water outlet pipes are directly provided on the water inlet pipe 11, high-pressure water can be discharged more quickly, so that the bristles 52 of the brush 5 are wetted more quickly. The nozzle 16 provided at the lower end can form multiple water spraying points between the two brushes 5, and can directly flush the outer surface of the cleaned object during the mobile cleaning process, so as to achieve a better cleaning effect.
[0020] Furthermore, the brush 5 is disc-shaped, and the brush body drive box 1 is circular; the water spray ports 15 may be distributed in a circular shape, corresponding to the positions of the bristles 52. When the pressure is sufficient, the water spray ports 15 are sufficient to inject water into the brush 5, so the left and right water outlet pipes can be blocked at this time, or the left and right water outlet pipes are not used. In a specific application, the brush body 51 drive box may also be a regular polygon. In order to facilitate the maintenance of internal parts, the brush body drive box 1 may be assembled from a left shell and a right shell, and the left and right shells are sealed and connected. In this way, the brush 5 has bristles 52 circumferentially, so that when the brush 5 continues to rotate, the bristles 52 are always in contact with the outer surface of the object to be cleaned.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
