Description

Technical Field

[0001] This utility model relates to the field of high-pressure flushing technology, and in particular to a high-pressure flushing cleaning device for a vacuum truck. Background Technology

[0002] In the field of municipal cleaning and pipeline maintenance, the vacuum cleaning vehicle is a highly efficient piece of equipment that integrates vacuuming and high-pressure flushing functions. It is widely used for dredging and cleaning operations in sewers and drainage pipes. One of its core working components is the high-pressure flushing cleaning device that penetrates deep into the pipes. This device delivers high-pressure water to the nozzle at the front end through a high-pressure resistant pipe. The high-pressure water jet from the nozzle impacts the dirt on the inner wall of the pipe, and the reaction force generated by the water jet propels the nozzle forward inside the pipe, achieving a thorough cleaning. Simultaneously, negative pressure can be used to collect waste, significantly improving the efficiency and convenience of pipeline cleaning.

[0003] However, the high-pressure flushing cleaning devices on traditional vacuum cleaning trucks typically have a fixed angle for the rear spray nozzles. This fixed-angle structure has significant limitations when dealing with complex pipeline environments: firstly, when the pipeline has 90-degree bends, 45-degree bends, or slight inclinations, the fixed-angle rear spray nozzles cannot adjust the thrust direction, causing the nozzles to easily get stuck at corners and hindering smooth passage through complex pipelines; secondly, for pipelines of different diameters, the fixed-angle rear spray nozzles cannot balance forward momentum and flushing range. When the pipe diameter is small, it is difficult to provide concentrated recoil force to ensure forward efficiency; when the pipe diameter is large, it is impossible to achieve wide-area flushing through dispersed water flow, thus restricting cleaning effect and operational efficiency. Therefore, this application proposes a high-pressure flushing vacuum truck cleaning device to solve the above problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a high-pressure flushing vacuum truck cleaning device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-pressure flushing vacuum truck cleaning device includes a high-pressure resistant pipe. A water rat nozzle is fixedly installed at the end of the high-pressure resistant pipe. Several angle-adjustable nozzles are fixedly installed in a ring on the water rat nozzle. Each angle-adjustable nozzle is composed of an external threaded connector, a spherical component, a connecting post, and an end block. The spherical component is rotatably installed inside the external threaded connector. The connecting post is fixedly installed on the outer wall of the spherical component. The end block is fixedly installed at one end of the connecting post. Several adjustment and fixing components are fixedly installed in a ring on the water rat nozzle. Each adjustment and fixing component is composed of a connecting frame, a connecting block, a threaded post, and an internal threaded tube. Two of each of the connecting frame, connecting block, and threaded post are provided. The connecting block is rotatably installed on the connecting frame. The threaded post is fixedly installed at one end of the connecting block. The internal threaded tube is installed on the two threaded posts.

[0007] Preferably, the high-pressure resistant pipe is fixedly installed on the vacuum cleaning vehicle.

[0008] Preferably, one end of the water rat nozzle is fixedly installed with an external threaded connecting pipe, the external threaded connecting pipe is fixedly installed inside a high-pressure resistant pipe, and a plurality of threaded holes are formed in a ring on the outer wall of the water rat nozzle, and spray holes are formed on the inner wall of the threaded holes.

[0009] Preferably, the external threaded connector on the angle adjusting nozzle is installed in the threaded hole, the inner end of the external threaded connector has a first hole, the outer end of the external threaded connector has an arc-shaped groove, and the first hole and the arc-shaped groove are interconnected.

[0010] Preferably, the spherical component on the angle adjusting nozzle is rotatably mounted in the arc-shaped groove, and a second hole is provided in the spherical component and the connecting column, through which the spherical component and the connecting column pass. A third hole is provided in the end block, through which the end block passes.

[0011] Preferably, the two connecting brackets on the adjusting and fixing assembly are respectively fixedly installed on the outer wall of the water rat nozzle and one end of the end block.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By incorporating an angle-adjustable nozzle—comprising an externally threaded connector, a spherical component, a connecting post, and an end block—into the water rat nozzle, the spherical component can rotate within the arc-shaped groove of the externally threaded connector, thereby rotating the connecting post and end block. This allows for flexible adjustment of the water rat nozzle's spray angle, enabling it to adapt to pipes of varying diameters and complex pipe environments with bends. When the pipe has a 90-degree bend, a 45-degree bend, or a slight inclination, the angle of the adjustable nozzle can be adjusted to change the water flow direction, preventing the water rat nozzle from getting stuck at corners. Furthermore, for different pipe diameters, adjusting the nozzle angle can balance the forward momentum and flushing range. For smaller pipe diameters, it can concentrate the water flow to provide sufficient recoil force to ensure efficient forward movement. With a larger pipe diameter, the water flow can be dispersed to achieve a wide-area flushing, improving cleaning effect and work efficiency. By setting an adjustment and fixing assembly consisting of a connecting frame, connecting block, threaded column, and internal threaded tube on the water rat nozzle and angle adjustment nozzle, the angle of the angle adjustment nozzle can be adjusted by rotating the internal threaded tube. Since the two threaded columns are respectively engaged with the internal threaded tube and the thread directions are opposite, rotating the internal threaded tube can make the two threaded columns move closer or further apart, thereby driving the angle adjustment nozzle to adjust its angle through the connecting block and connecting frame. After the adjustment is completed, stop rotating the internal threaded tube, and the angle of the angle adjustment nozzle is fixed, ensuring that the nozzle angle remains stable under the impact of high-pressure water flow and will not deviate, thus ensuring the stability and reliability of cleaning operations.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 - Figure 5 As shown, a high-pressure flushing vacuum truck cleaning device includes a high-pressure resistant pipe 1. A water rat nozzle 3 is fixedly installed at the end of the high-pressure resistant pipe 1. Several angle-adjustable nozzles 4 are fixedly installed in a ring on the water rat nozzle 3. Each angle-adjustable nozzle 4 consists of an external threaded connector 9, a spherical component 12, a connecting post 13, and an end block 15. The spherical component 12 is rotatably installed inside the external threaded connector 9. The connecting post 13 is fixedly installed on the outer wall of the spherical component 12. The end block 15 is fixedly installed at one end of the connecting post 13. Several adjusting and fixing components 5 are fixedly installed in a ring on the water rat nozzle 3. The adjusting and fixing components 5 are also fixedly installed on the angle-adjustable nozzles 4. The adjusting and fixing assembly 5 consists of a connecting frame 17, a connecting block 18, a threaded post 19, and an internally threaded tube 20. Two of each of the connecting frame 17, connecting block 18, and threaded post 19 are provided. The connecting block 18 is rotatably mounted on the connecting frame 17, and the threaded post 19 is fixedly mounted on one end of the connecting block 18. The internally threaded tube 20 is mounted on both threaded posts 19. An angle-adjusting nozzle 4, consisting of an externally threaded connector 9, a spherical component 12, a connecting post 13, and an end block 15, is installed on the water rat nozzle 3. The spherical component 12 can rotate within the arc-shaped groove 11 of the externally threaded connector 9, thereby driving the connecting post 13 and the end block 15 to rotate, thus achieving the adjustment of the water rat nozzle 3. The flexible adjustment of the spray angle allows the Water Rat Sprayer 3 to adapt to pipes of different diameters and complex pipe environments with bends. When the pipe has a 90-degree bend, a 45-degree bend, or a slight inclination, the angle of the adjustable nozzle 4 can be adjusted to change the direction of the water jet, preventing the Water Rat Sprayer 3 from getting stuck at corners. Simultaneously, for different pipe diameters, the angle of the adjustable nozzle 4 can be adjusted to balance the forward momentum and the flushing range. When the pipe diameter is small, the water flow can be concentrated to provide sufficient recoil force to ensure forward efficiency; when the pipe diameter is large, the water flow can be dispersed to achieve a wide-area flushing, improving cleaning effect and work efficiency. The Water Rat Sprayer 3 and the angle-adjusting nozzle 4 are connected by a... The adjustment and fixing assembly 5, consisting of frame 17, connecting block 18, threaded post 19, and internal threaded tube 20, can adjust the angle of the angle-adjusting nozzle 4 by rotating the internal threaded tube 20. Since the two threaded posts 19 are respectively engaged with the internal threaded tube 20 and the thread directions are opposite, rotating the internal threaded tube 20 can make the two threaded posts 19 move closer or further away from each other, thereby driving the angle adjustment nozzle 4 to adjust through the connecting block 18 and connecting frame 17. After the adjustment is completed, stop rotating the internal threaded tube 20, and the angle of the angle-adjusting nozzle 4 is fixed, ensuring that the nozzle angle remains stable under the impact of high-pressure water flow and will not deviate, thus ensuring the stability and reliability of the cleaning operation.

[0022] Specifically, the high-pressure resistant pipe 1 is fixedly installed on the vacuum cleaning vehicle 2. One end of the water rat nozzle 3 is fixedly installed with an externally threaded connecting pipe 8, which is fixedly installed inside the high-pressure resistant pipe 1. Several threaded holes 6 are annularly formed on the outer wall of the water rat nozzle 3. Spray holes 7 are formed on the inner wall of the threaded holes 6. An externally threaded connector 9 on the angle-adjusting nozzle 4 is installed inside the threaded holes 6. A first hole 10 is formed at the inner end of the externally threaded connector 9, and an arc-shaped groove 11 is formed at the outer end of the externally threaded connector 9. The first hole 10 and the arc-shaped groove 11 are interconnected. A spherical component 12 on the angle-adjusting nozzle 4 is rotatably installed inside the arc-shaped groove 11. A second hole 14 is formed inside the spherical component 12 and the connecting post 13, penetrating both the spherical component 12 and the connecting post 13. A third hole 16 is formed inside the end block 15, penetrating the end block 15. Two connecting brackets 17 on the adjusting and fixing assembly 5 are respectively fixedly installed on the outer wall of the water rat nozzle 3 and one end of the end block 15. When cleaning bends in the pipe, the angle of the nozzle 4 can be adjusted according to the bend. Before placing the water rat nozzle 3 into the bend, the angle of one side of the angle-adjusting nozzle 4 should be increased to give the water rat nozzle 3 a thrust that is biased towards the inside of the bend, preventing it from getting stuck at the bend and allowing it to pass through complex pipes more smoothly. When cleaning pipes of different diameters, if the pipe diameter is small, a concentrated recoil force is needed to push the nozzle forward, that is, the angle of all angle-adjusting nozzles 4 should be decreased. If the pipe diameter is large, the dispersed recoil force can allow the nozzle to move more stably in the center of the pipe, while using the dispersed water flow to flush a larger area of ​​the inner wall. At this time, the angle of all angle-adjusting nozzles 4 should be increased. When the pipe is flushed, the suction pipe of the vacuum cleaning vehicle 2 can be placed into the dirty area, and then the vacuum pump on the vacuum cleaning vehicle 2 can be started to create a negative pressure in the tank on the vacuum cleaning vehicle 2. The liquid and semi-liquid dirt is sucked into the tank by the air pressure difference. After absorption, the vacuum pump can be turned off and the suction pipe can be retracted.

[0023] Before use, the high-pressure resistant pipe 1 is fixedly installed on the power system of the vacuum cleaning vehicle 2. The water rat nozzle 3 is fixedly installed on the end of the high-pressure resistant pipe 1 through the external threaded connecting pipe 8. The external threaded connector 9 of the angle adjusting nozzle 4 is installed in the threaded hole 6 of the water rat nozzle 3. At this time, the first hole 10 on the external threaded connector 9 is connected to the spray hole 7. During operation, the power system of the vacuum cleaning vehicle 2 provides high-pressure water flow. The water flow enters the water rat nozzle 3 through the high-pressure resistant pipe 1, enters the first hole 10 on the external threaded connector 9 through the spray hole 7, and then sprays out through the second hole 14 on the spherical part 12 and the connecting column 13, and the third hole 16 on the end block 15 in sequence, realizing the flushing and cleaning of the pipe. During this process, the water rat nozzle 3 will move forward in the pipe with the help of the reaction force generated by the water jet; when according to When adjusting the angle of the nozzle 4 to meet operational needs due to pipe bends or changes in pipe diameter, the internal threaded pipe 20 on the adjusting fixing component 5 can be rotated. Since the two threaded posts 19 are respectively engaged with the internal threaded pipe 20 and the thread directions are opposite, rotating the internal threaded pipe 20 can make the two threaded posts 19 move closer or further away from each other. This, in turn, drives the spherical part 12 of the angle adjusting nozzle 4 to rotate in the arc groove 11 through the connecting block 18 and the connecting frame 17. When the spherical part 12 rotates, it drives the connecting post 13 and the end block 15 to rotate, so that the angle between the third hole 16 on the end block 15 and the water flow channel formed by the second hole 14 on the spherical part 12 and the connecting post 13 and the first hole 10 of the external threaded connector 9 changes. After adjusting to the appropriate angle, the rotation of the internal threaded pipe 20 can be stopped. At this time, the angle of the angle adjusting nozzle 4 will be fixed by the adjusting fixing component 5.

[0024] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
