That is, the high-pressure flushing head can only move forward automatically but cannot retreat automatically. The retreat requires human or mechanical pulling, resulting in low work efficiency and increased labor intensity of operators. Utility Model Content
[0003] The purpose of the utility model is to provide a pipeline high-pressure dredging device to solve the above problems.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A pipeline high-pressure dredging device comprises a high-pressure cleaning head and a pressure control console, wherein the high-pressure cleaning head comprises a high-pressure water pipe joint and a spray mechanism arranged at one end of the high-pressure water pipe joint, the spray mechanism comprises a shell and a fixed plate arranged in the shell, a plurality of through holes are arranged on the fixed plate, a fixed pipe is arranged on the side of the fixed plate facing the high-pressure water pipe joint, the top surface of the fixed pipe is open, an annular pressure slider is sleeved on the outer periphery of the fixed pipe, a plurality of springs are arranged between the pressure slider and the fixed plate, a limiting ring is arranged on the inner wall of the shell to limit the end of the pressure slider away from the spring, a plurality of central water distribution holes are evenly pierced on the side wall of the fixed pipe, a plurality of forward jet ports are evenly pierced on the outer wall of the shell near the high-pressure water pipe joint, the water outlet of the forward jet port is arranged toward the direction of the high-pressure water pipe joint, a plurality of reverse jet ports are evenly pierced on the outer wall of the shell away from the high-pressure water pipe joint, the water outlet of the reverse jet port is opposite to the water outlet direction of the forward jet port; a high-pressure water pipe is arranged between the high-pressure water pipe joint and the water outlet of the pressure control console for communication.
[0006] In order to further realize the utility model, the shell is an integrated structure, including an expanded area and a conical area, the end of the expanded area away from the conical area is connected to the high-pressure water pipe joint, the fixed plate is arranged at the intersection of the expanded area and the conical area, the forward injection port is arranged in the expanded area, and the reverse injection port is arranged in the conical area.
[0007] In order to further realize the utility model, the distance between the forward injection port and the high-pressure water pipe joint is smaller than the distance between the central water distribution hole and the high-pressure water pipe joint. When the water pressure of the central water distribution hole is lower than that of the spring, the pressure slider moves upward, and the water flows through the hole to the reverse injection port, and moves up and down under the different forces of the spring and the pressure slider, opening or closing the central water distribution hole and the forward injection port.
[0008] In order to further realize the utility model, the two ends of the spring are fixedly connected to the pressure slider and the fixing plate respectively.
[0009] In order to further realize the utility model, the fixing plate is circular, and the through holes are radially and evenly arranged on the fixing plate with the center of the fixing plate as the center. The diameter of the through holes is smaller than the inner diameter of the spring, and the axis of the spring overlaps with the center of the through holes.
[0010] In order to further realize the utility model, one end of the forward injection port communicating with the inner wall of the shell is a horizontal end, and one end of the forward injection port communicating with the outer wall of the shell is an inclined end.
[0011] In order to further realize the utility model, the number of the through holes is greater than the number of the springs.
[0012] In order to further realize the utility model, the center of the circle of the fixing plate overlaps with the axis of the fixing tube.
[0013] In order to further realize the utility model, the pressure sliding block is sandwiched between the inner wall of the shell and the outer wall of the fixed tube.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] The utility model discloses a high-pressure cleaning head which controls the upward and downward movement of the pressure slider by balancing the force generated by the water pressure on the pressure slider and the action force of the spring. The spring contracts when the water pressure is greater than the spring pressure, and stretches when the water pressure is less than the spring pressure. The water flow is changed to pass through the central water distribution hole to be opened and sprayed from the reverse jet port or the forward jet port to form a certain impact force, thereby pushing the high-pressure cleaning head forward or backward to achieve its automatic advance and retreat or impact function.
[0016] The utility model can change the forward or backward movement of the high-pressure cleaning head by controlling the flushing pressure, thereby solving the problem that the cleaning heads currently on the market can only automatically move forward but not automatically move backward.

[0023] The shell 2 is an integrated structure, including an expansion area 2-1 and a conical area 2-2. The end of the expansion area 2-1 away from the conical area 2-2 is connected to the high-pressure water pipe joint 1. The fixing plate 3 is arranged at the intersection of the expansion area 2-1 and the conical area 2-2.
