[0043] Embodiment 1:

[0044] This embodiment provides a cleaning device for a negative pressure pipe, comprising:

[0045] Support frame 1;

[0046] A liquid storage tank 2, the liquid storage tank 2 is installed on the support frame 1, and the liquid storage tank 2 is provided with a connection port 3 for inputting and outputting liquid, and the connection port 3 can be connected to the negative pressure pipeline of the formation equipment;

[0047] An air pressure regulating mechanism, the air pressure regulating mechanism is arranged on the support frame 1 and is connected to the liquid storage tank 2, and the air pressure regulating mechanism includes a positive pressure regulator 4 and a negative pressure regulator 5; the positive pressure regulator 4 is used to make the liquid storage tank 2 in a positive pressure state and push the liquid from the liquid storage tank 2 through the connecting port 3 to the negative pressure pipeline of the formation equipment, and the negative pressure regulator 5 is used to make the liquid storage tank 2 in a negative pressure state and suck the liquid from the negative pressure pipeline of the formation equipment into the liquid storage tank 2 through the connecting port 3;

[0048] The control module 6 is disposed on the support frame 1 , and is used to control the operation of the air pressure regulating mechanism and the opening and closing of the connecting port 3 .

[0049] Furthermore, the cleaning device further comprises a touch screen 7 , which is electrically connected to the control module 6 and is used for an operator to set specific cleaning parameters.

[0050] In the present technical solution, both the positive pressure regulator 4 and the negative pressure regulator 5 are connected to an external gas source, and the liquid is a cleaning agent.

[0051] The starting operation of the cleaning device is as follows: first, connect the connecting port 3 of the liquid storage tank 2 and the cleaning agent tank. Since the positive pressure regulator 4 and the negative pressure regulator 5 are both connected to the liquid storage tank 2, and the operation of the positive pressure regulator 4 and the negative pressure regulator 5 is controlled by the control module 6, and the control module 6 is electrically connected to the touch screen 7, the negative pressure regulator 5 can be opened through the touch screen 7 to make the liquid storage tank 2 in a negative pressure state, so that the cleaning agent in the cleaning agent tank can be sucked into the liquid storage tank 2, and then the connecting port 3 is closed to store the cleaning agent in the liquid storage tank 2.

[0052] The cleaning work of the cleaning device is described as follows: the connecting port 3 is then connected to the negative pressure pipeline of the formation equipment. Since the opening and closing of the connecting port 3 is also controlled by the control module 6, the connecting port 3 and the positive pressure regulator 4 can be opened through the touch screen 7. The external air source transmits positive air pressure to the liquid storage tank 2 through the positive pressure regulator 4, and the cleaning agent in the liquid storage tank 2 is pushed from the connecting port 3 to the negative pressure pipeline. Then the connecting port 3 and the positive pressure regulator 4 are closed, and the cleaning agent is allowed to stand in the negative pressure pipeline to clean the negative pressure pipeline. After standing for a period of time, the connecting port 3 and the negative pressure regulator 5 are opened again, so that the liquid storage tank 2 is in a negative pressure state, so that the cleaning agent can be drawn back from the negative pressure pipeline into the liquid storage tank 2, thereby completing a whole cleaning process.

[0053] It is worth mentioning that the cleaning process can be set to perform multiple cycles, and the above actions can be repeated multiple times, thereby improving the cleaning effect of the negative pressure pipe.

[0054] Through this structural design, the cleaning agent is pumped into the liquid storage tank 2 by the negative pressure regulator 5, and then the cleaning agent is injected into the negative pressure pipeline of the formation equipment by the positive pressure regulator 4, so as to clean the negative pressure pipeline. There is no need for the operator to directly contact the negative pressure pipeline and the cleaning agent, which effectively improves the convenience of cleaning the negative pressure pipeline and reduces the risk of the operator being corroded and injured by the cleaning agent.
