Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1 A high-pressure water flow equipment for cleaning a boiler in a power plant comprises a base 1, a liquid storage tank 2 fixedly connected to the top of the base 1, a support frame 5 fixedly connected to the top of the base 1 and a horizontal plate 51 fixedly connected to one side of the support frame 5, and a flushing component 3 for cleaning the boiler is arranged above the liquid storage tank 2.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 5The flushing assembly 3 includes a water pump 31 fixedly connected to the top of the liquid storage tank 2, a delivery pipe 32 fixedly connected to the top of the water pump 31, a first mounting plate 33 fixedly passing through one end of the delivery pipe 32, a spray pipe 34 fixedly passing through the bottom end of the first mounting plate 33, a first spray port 341 provided on the outer surface of the spray pipe 34, a second mounting plate 35 fixedly passing through the bottom end of the spray pipe 34, a second spray port 351 provided at the bottom end of the second mounting plate 35, and an electric push rod 36 arranged between the cross plate 51 and the first mounting plate 33, wherein the fixed end of the electric push rod 36 is fixedly connected to the cross plate 51, the telescopic end of the electric push rod 36 is fixedly connected to the first mounting plate 33, and the delivery pipe 32 is fixedly connected to the cross plate 51. The plate 51 is connected through, and there are multiple groups of spray pipes 34. Cleaning liquid is placed in the liquid storage tank 2. Under the action of the water pump 31, the cleaning liquid enters the spray pipe 34 and the second mounting plate 35 through the transmission pipe 32 and the first mounting plate 33 in turn, and is finally sprayed out through the first spray port 341 and the second spray port 351. The cleaning liquid sprayed from the first spray port 341 flushes the side wall of the boiler, and the cleaning liquid sprayed from the second spray port 351 cleans the bottom end of the inner wall of the boiler. The electric push rod 36 is extended and retracted to drive the first mounting plate 33 to move up and down, thereby driving the spray pipe 34 and the second mounting plate 35 to move up and down. The spray pipe 34 and the second mounting plate 35 move up and down to clean the inside of the boiler in all directions.

[0026] The transmission tube 32 is a telescopic hose, which has the characteristic of free expansion and contraction, and is convenient for expansion and contraction according to actual needs. When the electric push rod 36 expands and contracts to drive the first mounting plate 33 to move up and down, the first mounting plate 33 drives the transmission tube 32 to expand and contract.

[0027] A fixing assembly 4 for fixing the conveying tube 32 is arranged above the transverse plate 51. The fixing assembly 4 includes an arc-shaped fixing plate 41 fixedly connected to the top of the transverse plate 51, a spring 42 fixedly connected to the inner side of the arc-shaped fixing plate 41, and an arc-shaped fixing block 43 fixedly connected to one end of the spring 42. The arc-shaped fixing block 43 is brought into contact with the outer surface of the fixed conveying tube 32. At this time, the spring 42 is in a compressed state under pressure. The reaction force generated by the compression of the spring 42 acts on the outer surface of the conveying tube 32 through the arc-shaped fixing block 43, which is convenient for fixing the arc-shaped fixing block 43.

[0028] The arc-shaped fixing block 43 is a component made of a rubber material. The rubber material is soft and has good wear resistance. When it contacts the outer surface of the conveying pipe 32, it is convenient to reduce the wear and damage of the outer surface of the conveying pipe 32.

[0029] A motor 6 is fixedly connected to the top of the liquid storage tank 2, a connecting rod 61 is fixedly connected to the output end of the motor 6, a stirring frame 611 is fixedly connected to the outer surface of the connecting rod 61, the connecting rod 61 is connected through the liquid storage tank 2, and the motor 6 is started, the motor 6 drives the connecting rod 61 to rotate, and the rotation of the connecting rod 61 drives the stirring frame 611 to rotate, so as to prevent the cleaning liquid inside the liquid storage tank 2 from precipitating.

[0030] A push handle 12 is fixedly connected to the top of the base 1, and a universal wheel 11 is fixedly connected to the bottom of the base 1. By pushing the push handle 12, the base 1 can be moved to a designated position under the action of the universal wheel 11 to clean different boilers.

[0031] When in use, open the boiler cover, push the push handle 12, and move the base 1 to the specified position under the action of the universal wheel 11. At this time, the second mounting plate 35 is located above the boiler, and the electric push rod 36 is started. The electric push rod 36 extends downward to drive the first mounting plate 33 to move downward, thereby driving the liquid spraying pipe 34 and the second mounting plate 35 to move downward, so that the first mounting plate 33 is inside the boiler, and the motor 6 is started. The motor 6 drives the connecting rod 61 to rotate, and the rotation of the connecting rod 61 drives the stirring frame 611 to rotate to prevent the cleaning of the inside of the liquid storage tank 2. The liquid produces precipitation. Under the action of the water pump 31, the cleaning liquid enters the liquid spraying pipe 34 and the second mounting plate 35 through the transmission pipe 32 and the first mounting plate 33 in turn, and is finally sprayed out through the first liquid spraying port 341 and the second liquid spraying port 351. The cleaning liquid sprayed from the first liquid spraying port 341 rinses the side wall of the boiler, and the cleaning liquid sprayed from the second liquid spraying port 351 cleans the bottom end of the inner wall of the boiler. The electric push rod 36 is then extended and retracted to drive the liquid spraying pipe 34 and the second mounting plate 35 to move up and down inside the boiler, so as to clean the inside of the boiler in all directions.
