DETAILED DESCRIPTION

[0028] Below, combining the drawings and specific embodiment, the utility model is described further, need explaining, under the premise of not conflicting, the following description between each embodiment of various embodiments or between each technical feature can be combined to form new embodiment.

[0029] Please combine Figures 1-6 The high-pressure spray cleaning device of the pipeline robot of the embodiment comprises an installation cylinder 1 and an inlet pipe 2. First, a pipeline assembly 3 is fixedly installed in the inside of the installation cylinder 1, one end of the inlet pipe 2 is connected with an external water source, one end extends into the inside of the installation cylinder 1 and is connected with the pipeline assembly 3.

[0030] A spray head 4 is also installed on the installation cylinder 1, wherein the spray head 4 comprises a main spray head 41 and an adjustable spray head 42. The main spray head 41 and the adjustable spray head 42 are connected with the pipeline assembly 3 through an elastic connecting hose 43. The main spray head 41 is fixedly installed at the front end of the installation cylinder 1.

[0031] In order to install the adjustable spray head 42, three installation ports 5 are circumferentially formed along the installation cylinder 1, a rotating frame 6 is arranged in the installation port 5, a connecting shaft 7 is connected to the end of the rotating frame 6, and the rotating frame 6 is rotatably installed in the installation port 5 through the connecting shaft 7. The adjustable spray head 42 is fixedly connected in the inside of the rotating frame 6.

[0032] It should be noted that when the adjustable nozzle 42 is selected, the nozzle 4 with the control switch 44 needs to be driven. That is, the opening or closing of the adjustable nozzle 42 can be controlled through the control switch 44. And in the initial state, the adjustable nozzle 42 and the main nozzle 41 are opposite in direction. That is, the main nozzle 41 faces the front of the mounting barrel 1, and the adjustable nozzle 42 faces the rear of the mounting barrel 1.

[0033] In the initial state, the adjustable nozzle 42 is in the mounting port 5, and the adjustable nozzle 42 is closed through the control switch 44. At this time, only the main nozzle 41 is normally used, and the water flow sprayed through the main nozzle 41 is used to flush the pipeline. Since the direction of the main nozzle 41 is fixed, it can only move forward along the pipeline, and it can flush the blockage in the pipeline, but the cleaning ability of the inner wall of the pipeline is weak, and the water flow direction of the main nozzle 41 is forward, so it is difficult to bring the blockage in the pipeline out of the pipeline.

[0034] Therefore, the adjusting structure 8 is also arranged in the mounting barrel 1, and the adjusting structure 8 is used to adjust the angle of the adjustable nozzle 42. Specifically, the adjusting structure 8 includes a fixed wedge block 81, a movable wedge block 84, and a moving ring 83.

[0035] First, the top of the fixed wedge block 81 is rotatably connected with a spherical connecting piece 86, and the spherical connecting piece 86 is composed of a spherical ball at the top and a connecting rod at the lower end, wherein the upper end of the spherical connecting piece 86 is rotatably connected to the bottom of the rotating frame 6. The fixed wedge block 81 is provided with a dovetail-shaped limiting groove 82. The movable wedge block 84 is fixedly provided with a corresponding limiting strip 85, and the limiting strip 85 is slidably installed in the limiting groove 82. And the contact surface of the fixed wedge block 81 and the movable wedge block 84 is a slope. Therefore, if the movable wedge block 84 moves horizontally, it will push the fixed wedge block 81 upward. The movable wedge block 84 will push the rotating frame 6 to move through the spherical connecting piece 86, and the rotating frame 6 will rotate around the connecting shaft 7. Therefore, the spherical connecting piece 86 is rotatably connected with the fixed wedge block 81 and the rotating frame 6, so as to push the rotating frame 6 to rotate around the axial direction of the connecting shaft 7.

[0036] The above-mentioned fixed wedge block 81 is provided with three, and the movable wedge block 84 is also provided with three, in order to connect the three movable wedge blocks 84, the moving ring 83 is arranged. The three movable wedge blocks 84 are fixedly connected to the moving ring 83. And a cavity needs to be arranged in the inside of the mounting barrel 1 for the movement of the moving ring 83 and the movable wedge block 84. And it should be noted that the movable wedge block 84 and the fixed wedge block 81 cannot be separated.

[0037] Therefore, the movable wedge block 84 and the moving ring 83 are also in the inside of the mounting barrel 1, in order to facilitate the movement of the moving ring 83. Therefore, the control barrel 9 is also arranged. The control barrel 9 is composed of a connecting section 91, a threaded section 92, and a control section 93.

[0038] First, one end of the connecting section 91 is provided with a connecting notch 94, one end of the above-mentioned moving ring 83 is rotatably connected in the connecting notch 94 through a bearing. The outer surface of the connecting section 91 is fixedly connected with external threads, and a corresponding internal thread is formed on the inner wall of the mounting cylinder 1. The control section 93 is connected with the threaded section 92, and the control section 93 is located outside the mounting cylinder 1. The threaded section 92 can be rotated through the control section 93.

[0039] Therefore, when the control section 93 is manually operated to rotate (the mounting cylinder 1 is fixed), the control cylinder 9 can be driven to rotate and move outward of the mounting cylinder 1 due to the cooperation of the threads.

[0040] The rotation of the control cylinder 9 does not affect the moving ring 83, but when the control cylinder 9 moves, the moving ring 83 is driven to move together.

[0041] The connecting plate 10 is further fixedly connected to the bottom of the mounting cylinder 1, and the connecting plate 10 is used to connect the mounting cylinder 1 and the pipeline robot.

[0042] The implementation process and principle of the high-pressure spray cleaning device of the pipeline robot in the embodiment of the present application are as follows:

[0043] (1) In the initial state, the adjustable nozzle 42 is inside the mounting port 5 and in the closed state. At this time, the mounting cylinder 1 is sent into the pipeline through the pipeline robot, and high-pressure water flow is sprayed out through the main nozzle 41 to flush the pipeline.

[0044] (2) Refer to Figure 2 , the control cylinder 9 is rotated to move the control cylinder 9 outward of the mounting cylinder 1 (in the left direction). The control cylinder 9 drives the moving ring 83 to move leftward. Since the contact surface of the fixed wedge block 81 and the movable wedge block 84 is a slope, the movable wedge block 84 drives the fixed wedge block 81 to move upward when the movable wedge block 84 moves. The fixed wedge block 81 drives the rotating frame 6 to rotate around the connecting shaft 7 through the spherical connecting piece 86 connected in rotation. One end of the adjustable nozzle 42 is lifted.

[0045] At this time, the control switch 44 of the adjustable nozzle 42 is opened, so that the adjustable nozzle 42 is inclined upward and opposite to the direction of the main nozzle 41.

[0046] Therefore, on the one hand, in the process that the pipeline robot penetrates into the inside of the pipeline to be cleaned, the water flow sprayed by the adjustable nozzle 42 can be washed to the inner wall of the pipeline, so that the dirt and scale attached to the inner wall of the pipeline can be more easily removed; on the other hand, when the pipeline robot exits from the inside of the pipeline, the adjustable nozzle 42 can easily push the dirt flushed from the pipeline out of the pipeline.

[0047] That is, in the process that the adjustable nozzle 42 penetrates into the pipeline, the inner wall of the pipeline can be cleaned, and in the process that the adjustable nozzle 42 moves out of the pipeline, the dirt can be pushed out of the pipeline while the cleaning effect is achieved.

[0048] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application belong to the scope of protection required by the present application.
