Description

Technical Field

[0001] The utility model belongs to the technical field of mobile spraying, in particular to a polyurea spraying device applied to a pumped storage power station. Background Art

[0002] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse the spray into uniform and fine droplets by pressure or centrifugal force and apply it to the surface of the object. It can be divided into air spray, airless spray, electrostatic spray and various derivative methods of the above basic spray forms, such as high-flow low-pressure atomization spray, thermal spray, automatic spray, multi-group spray, etc.

[0003] Polyurea is an elastomeric substance generated by the reaction of isocyanate components and amino compound components. It is divided into pure polyurea and semi-polyurea, and their properties are different. The most basic properties of polyurea are anti-corrosion, waterproof, and wear resistance.

[0004] However, the existing spraying vehicles cannot adjust the spraying amount according to the moving speed of the spraying vehicle. When the moving speed of the spraying vehicle changes, the sprayed polyurea coating will become thicker or thinner, which not only easily causes waste of polyurea materials but also affects the spraying quality. In addition, polyurea is easy to solidify when it is stationary, which is not very convenient to use.

[0005] Therefore, we need to design a polyurea spraying device for use in pumped storage power stations to solve these problems. Utility Model Content

[0045] Specifically, a stirring shaft 5 is provided through the bottom of the storage tank 4, a plurality of stirring rods 6 are fixedly provided on the stirring shaft 5 located inside the storage tank 4, a driven gear 7 is fixedly provided at the end of the stirring shaft 5 located below the storage tank 4, and the driven gear 7 is meshed with the driving gear 205.

[0048] Specifically, a bracket 14 and a handle 22 are fixedly provided on the vehicle body 1 , and the bracket 14 is connected to the output pipe 17 . The bracket 14 is provided in this way so as to support the output pipe 17 , and the handle 22 is used to move the vehicle.

[0049] Specifically, a plurality of spray heads 16 are fixedly arranged on the spray pipe 15 , and the spray heads 16 are connected to the inside of the spray pipe 15 , so that polyurea can be sprayed.

[0050] Specifically, a support leg 9 is fixedly provided at the bottom of the storage tank 4, the storage tank 4 and the vehicle body 1 are connected to each other through the support leg 9, and a cover plate 21 is hinged on the top of the storage tank 4, so that debris can be prevented from falling into the storage tank 4 and contaminating the polyurea raw material.

[0051] Specifically, a one-way valve 20 is fixedly disposed in the output end, and the one-way valve 20 is located between the output end of the regulating mechanism 3 and the output end of the air compressor 13. Such a configuration can prevent the reverse flow of high-pressure gas while ensuring that polyurea can flow through.

[0052] The working process of this embodiment is as follows: when spraying, the cover plate 21 on the top of the storage tank 4 is opened, and then the polyurea is poured into the storage tank 4 and then the cover plate 21 is covered to prevent debris from falling in. Then the driving motor 201 is started. After the driving motor 201 rotates, it will drive the adjusting driving wheel 202 to rotate synchronously with the speed of the motor. At the same time, the output shaft 204 of the reducer 203 will drive the driving gear 205 and the traveling driving wheel 206 to rotate at a lower speed. After the driving gear 205 rotates, it will drive the meshing driven gear 7 to rotate. After the driven gear 7 rotates, it will drive the stirring shaft 5 to rotate. After the stirring shaft 5 rotates, it will drive the stirring rod 6 to rotate. After the stirring rod 6 rotates, it will stir the polyurea in the storage tank 4 to prevent the polyurea from solidifying and affecting the spraying. At the same time, the traveling driving wheel 206 will drive the traveling driven wheel 11 to rotate through the traveling transmission belt 12. After the traveling driven wheel 11 rotates, it drives the spraying vehicle to move through the wheels.

[0053] At the same time, since the adjusting drive wheel 202 rotates at the same speed as the driving motor 201, and the adjusting drive wheel 202 is connected to the adjusting driven wheel 308 through the adjusting transmission belt 19, the rotating disk 309 will rotate at the same speed as the driving motor 201 at this time, and the rotating disk 309 rotates the flyweight 312 which will be affected by the centrifugal force and move radially along the rotating disk 309, and the flyweight 312 is hinged to the rotating disk 309 through the connecting frame 310, so the free end of the connecting rod 311 will push the push plate 307 to move axially along the rotating disk 309, and the push plate 307 will compress the adjusting spring 313 when moving along the axial direction of the rotating disk 309, and at the same time, it will pull the piston 303 to move through the pull rod 305, and after the piston 303 moves, the through hole 304 will connect the connecting pipe 18 and the output pipe 17.

[0054] At this time, the air compressor 13 is started. After the air compressor 13 is started, high-pressure gas will be blown into the output pipe 17 through the output end. The one-way valve 20 will prevent the high-pressure gas from moving toward the spray pipe 15 through the output pipe 17 and spraying out from the nozzle 16. The polyurea in the storage tank 4 flows through the connecting pipe 18 and the through hole 304 and enters the discharge pipe. At the same time, due to the high-pressure air flowing out of the nozzle 16, the polyurea in the output pipe 17 at the input end of the one-way valve 20 will be sucked out and sprayed out through the nozzle 16.

[0055] When the rotation speed of the driving motor 201 increases, the moving speed of the trolley will increase, and the speed of the rotating disk 309 will become faster. The centrifugal force on the hammer 312 will become larger, and the piston 303 will be driven to move a longer distance through the pull rod 305, so that the connectivity between the through hole 304 and the connecting pipe 18 and the output pipe 17 increases, allowing more polyurea to flow through, thereby increasing the polyurea spraying and ensuring the spraying quality.

[0056] When the speed of the driving motor 201 decreases, the moving speed of the trolley will slow down. At this time, the speed of the rotating disk 309 will slow down, the centrifugal force on the fly hammer 312 will become smaller, and the adjusting spring 313 will push the push plate 307 to get closer to the rotating disk 309, and push the piston 303 to move in the opposite direction through the pull rod 305, thereby reducing the connection flux between the through hole 304 and the connecting pipe 18 and the output pipe 17, which can reduce the polyurea flowing through, thereby reducing the amount of polyurea sprayed, and avoiding excessive thickness of the sprayed polyurea leading to waste of raw materials.

[0057] The adjustment spring 313 can be compressed or released by adjusting the position of the thrust adjustment frame 306 through the thread, and the moving speed of the vehicle body 1 and the polyurea spraying speed can be matched by utilizing the coordination between the adjustment of the spring elastic force and the centrifugal force exerted on the fly hammer 312 .

[0058] In this embodiment, a feeding pump can be installed on the connecting pipe 18 or the output pipe 17 to transport the polyurea, so that the spray pipe and the spray head 16 can spray the polyurea.

[0059] The handle 22 on the vehicle body 1 can move the vehicle body 1 when the drive motor 201 is not rotating. Because the power wheel 8 is connected to the reducer 203, if it is moved directly or encounters greater resistance, the travel belt 12 can be removed when the vehicle body 1 is moved using the handle 22; or a tensioning pulley is set on the travel belt 12 between the travel driving wheel 206 and the travel driven wheel 11, and the tensioning pulley can be used to tighten the travel belt 12 when moving using the drive motor 201, and the tensioning pulley can be used to release the travel belt 12 when moving the vehicle body 1 using the handle 22.

[0060] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
