The water outlet end of the high-pressure unloading valve 11 communicates with the water tank 1 through a water pipe. When high-pressure water needs to be delivered for work, the high-pressure unloading valve 11 is closed. If the high-pressure unloading valve 11 is opened, the high-pressure water in the water diversion block 5 Water overflows back to the water tank 1 through the pipeline, and no longer outputs high-pressure water to the high-pressure control valve 6 .

2. Oil circuit part

In this embodiment, the high-pressure control valve 6 and the high-pressure unloading valve 11 are both provided with a hydraulic cylinder, and the high-pressure spray gun 12 is provided with a hydraulic motor 123 for driving the spray head to rotate. In order to make the high-pressure control valve 6, the high-pressure unloading valve 11 and the hydraulic motor 123 in the high-pressure spray gun work smoothly, it is necessary to configure corresponding hydraulic oil pipelines. There are many ways to implement the setting of the hydraulic oil pipeline. For example, a hydraulic oil pipeline supply system can be separately configured for each group of high-pressure water spray components. In order to improve the integration of the system and uniformly supply oil to the three groups of high-pressure water spray components, the invention is provided with a centralized hydraulic system. The centralized hydraulic system includes a mailbox 7, a hydraulic oil filter 8, a hydraulic pump 9 and a hydraulic valve block 10; the oil tank 7 is connected to the hydraulic pump 9 through the hydraulic oil filter 8, and the hydraulic pump 9 is connected to the hydraulic valve block 10 , the hydraulic valve block 10 is provided with a plurality of oil ports, which are respectively connected with the oil ports of the hydraulic cylinder of the high-pressure control valve 6, the hydraulic motor 123 of the high-pressure spray gun 12, and the hydraulic cylinder of the high-pressure unloading valve 11 .

The power of the aforementioned hydraulic cylinder and hydraulic motor 123 is provided by the oil pressure established by the hydraulic pump 9 . That is, the hydraulic oil in the oil tank 7 is filtered by the hydraulic oil filter 8 and then pressurized by the hydraulic pump 9 and delivered to the hydraulic valve block 10.

The other hydraulic solenoid control valve 14, that is, the fourth hydraulic solenoid control valve 144 controls the oil passage of the hydraulic cylinder on the high-pressure unloading valve 11; when the hydraulic electromagnetic unloading valve 15 is opened, the hydraulic pump 9 outputs The hydraulic oil directly overflows back to the oil tank 7, and the centralized hydraulic system has no oil pressure. When the hydraulic electromagnetic unloading valve 15 is closed, the hydraulic oil overflow port is closed, and oil pressure is established in the centralized hydraulic system.

The hydraulic solenoid control valve that controls the hydraulic motor 123 of any high-pressure spray gun 12 is simultaneously connected with the hydraulic cylinder of the high-pressure control valve 6 corresponding to the high-pressure spray gun, that is, one hydraulic solenoid control valve controls the oil passage of a group of high-pressure water spray components. . Both sides of the spool of any one of the hydraulic electromagnetic control valves 14 are provided with coils, and the two coils are respectively connected to two ports of the controller 13, and the two coils are not powered at the same time; as shown in Figure 2 , the two coils of the first hydraulic electromagnetic control valve 141 in this embodiment are respectively connected to the two ports P1 and P8 of the controller 13, and the two coils of the second hydraulic electromagnetic control valve 142 are respectively connected to the two ports P2 and P7. The two coils of the third hydraulic electromagnetic control valve 143 are respectively connected to the two ports P3 and P6, and the two coils of the fourth hydraulic electromagnetic control valve 144 are respectively connected to the two ports P4 and P5.

For any of the hydraulic solenoid control valves and the high-pressure water spray assembly controlled by it, since the two coils are not powered at the same time, when one of the coils is powered, the other coil, the B coil, is not powered. At this time, the spool moves toward the A coil, the hydraulic cylinder of the high-pressure control valve in the high-pressure water spray assembly and the oil circuit of the hydraulic motor of the high-pressure spray gun are connected, the high-pressure control valve is opened, and the high-pressure water enters the high-pressure spray gun and is sprayed out from the nozzle. , and the nozzle rotates under the drive of the hydraulic motor to achieve rotating water spray; when the B coil is energized, the A coil is not energized, and at this time the valve core moves to the B coil, and the hydraulic cylinder of the high-pressure control valve in the high-pressure water spray assembly And the oil circuit of the hydraulic motor of the high-pressure spray gun is disconnected, the high-pressure control valve is closed, the high-pressure water does not enter in the high-pressure spray gun, and the hydraulic motor of the high-pressure spray gun stops rotating.

5. Working method of multifunctional high-pressure water jet flushing device

The working process of the device will be described in detail below in conjunction with the drawings in the embodiments.

The controller 13 sends a closing signal to the hydraulic electromagnetic unloading valve 15, and the hydraulic electromagnetic unloading valve 15 is electrically activated to close the hydraulic oil overflow port, and then the centralized hydraulic system builds up oil pressure. The controller 13 sends a closing signal to the fourth hydraulic electromagnetic control valve 144 that controls the high pressure unloading valve 11, and the fourth hydraulic electromagnetic control valve 144 is electrically activated, and oil enters the upper cavity of the oil cylinder on the high pressure unloading valve 11 to make the valve core go down. Remove and close the overflow port, and the water system builds up high pressure. When a certain road spray gun is required to work, the controller 13 sends an opening signal to the hydraulic solenoid control valve 14 (such as the first hydraulic solenoid control valve 141) that controls the high pressure control valve 6 of the road, then the high pressure control valve 6 is opened, and the nozzle 129 outputs high pressure. water, and the hydraulic oil is output to the hydraulic motor 123 on the high-pressure spray gun 12 of the road, and the hydraulic motor 123 rotates to drive the spray nozzle 129 on the high-pressure spray gun 12 to rotate.

When it is necessary to switch to another spray gun to work, after the controller 13 sends an open signal to the hydraulic solenoid control valve 14 (such as the second hydraulic solenoid control valve 142), the high pressure control valve 6 of the other path is opened, and the nozzle 129 outputs high pressure. At the same time, the hydraulic motor 123 on the high-pressure spray gun 12 corresponding to the high-pressure control valve 7 of this road drives the nozzle 129 on it to rotate; at the same time, the controller 13 sends the hydraulic solenoid control valve 14 (that is, the first hydraulic pressure) to the original working road. Electromagnetic control valve 141) sends closing signal, then that way of original work stops conveying high-pressure water, and shower nozzle 129 stops rotating simultaneously.
