Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment accessories technology, and in particular to a multi-functional nozzle for downhole equipment maintenance. Background Technology

[0002] Underground mining requires a large number of mechanical equipment. Due to the special nature of the shaft, the maintenance of the equipment is carried out underground. The maintenance of mechanical equipment involves washing and painting, and spray nozzles are needed for washing and painting.

[0003] In the existing technology, in order to avoid wasting water resources, the water recovered in the well is used to flush the equipment. In order to achieve the flushing effect, high-pressure nozzles are mostly used. However, the recovered water contains impurities, which can easily cause the high-pressure nozzles to become clogged, causing inconvenience to the work and reducing work efficiency. In addition, when painting the equipment, professional painting equipment is required. Due to the small working space in the well, it is not possible to place a lot of equipment.

[0004] To address this, a multi-functional nozzle for downhole equipment maintenance has been proposed, which facilitates equipment rinsing and also allows for direct painting operations. Utility Model Content

[0005] This invention provides a multi-functional nozzle for downhole equipment maintenance to solve the problems mentioned in the background art.

[0006] To address the aforementioned problems, this utility model provides a multi-functional nozzle for downhole equipment maintenance, comprising an injection pipe, a gas chamber, an air inlet pipe, and a liquid inlet pipe. The injection pipe is fixed at the front end of the gas chamber and communicates with the interior of the gas chamber. The air inlet pipe is fixed at the rear end of the gas chamber opposite to the injection pipe and communicates with the interior of the gas chamber. The liquid inlet pipe is inclined and fixed at the bottom of the gas chamber and communicates with the interior of the gas chamber. The end of the air inlet pipe away from the gas chamber has a first threaded end, which is connected to a high-pressure gas pipe. The outer surface of the end of the liquid inlet pipe away from the gas chamber has a second threaded end, which is threadedly connected to a liquid inlet hose.

[0007] Preferably, the end of the injection pipe away from the gas chamber is provided with a flared opening.

[0008] Preferably, the air intake pipe is connected to the end portion inside the air chamber, and the connecting end is tapered.

[0009] Preferably, the outer surface of the liquid inlet tube is provided with a handheld end.

[0010] The beneficial effects of adopting the above technical solutions are:

[0011] By using an air inlet pipe in conjunction with a high-pressure air pipe, external high-pressure gas can be sent into the air chamber and then sprayed out from the spray pipe. The flow of gas in the air chamber creates a suction force on the liquid inlet pipe, which, in conjunction with the liquid inlet hose, can carry water or paint into the spray pipe for spraying. The high-pressure gas propulsion ensures the spraying effect. Since the spraying is propelled by high-pressure gas, it will not cause blockage, thus improving work efficiency. At the same time, no special painting equipment is required when spraying paint, making the work more convenient. Attached Figure Description

[0016] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1-3In this embodiment, a multi-functional nozzle for downhole equipment maintenance includes a jet pipe 1, a gas chamber 2, an air inlet pipe 3, and a liquid inlet pipe 4. The jet pipe 1 is fixed at the front end of the gas chamber 2 and communicates with the interior of the gas chamber 2. The air inlet pipe 3 is fixed at the rear end of the gas chamber 2 opposite to the jet pipe 1 and communicates with the interior of the gas chamber 2. The liquid inlet pipe 4 is inclined and fixed at the bottom of the gas chamber 2 and communicates with the interior of the gas chamber 2. The end of the air inlet pipe 3 away from the gas chamber 2 is provided with a first threaded end 31, which is connected to a high-pressure air pipe 32. The outer surface of the end of the liquid inlet pipe 4 away from the gas chamber 2 is provided with a second threaded end 41, which is threadedly connected to a liquid inlet hose 42.

[0020] With the above technical solution, the high-pressure air pipe 32 is threadedly connected to the first threaded end 31 of the air inlet pipe 3, and the liquid inlet hose 42 is threadedly connected to the second threaded end 41 of the liquid inlet pipe 4. The liquid inlet hose 42 is placed in water or a paint can, and then the air pump is started. The air pump generates gas, which is sent into the air inlet pipe 3 and then into the air chamber 2. The gas then enters the spray pipe 1 through the air chamber 2 and is sprayed out. Since the liquid inlet pipe 4 is connected to the air chamber 2, the gas flowing in the air chamber 2 generates suction on the liquid inlet pipe 4. The liquid inlet pipe 4, with the cooperation of the liquid inlet hose 42, draws water or paint into the air chamber 2 and sprays it out from the spray pipe 1 with the gas flow, completing the washing or painting operation of the equipment. Since the spraying effect is driven by high-pressure gas, it is less likely to cause blockage of the spray pipe 1, improving work efficiency. It also facilitates the painting of equipment without the need for a separate dedicated painting equipment, thus reducing operating costs.

[0021] Preferably, the end of the injection pipe 1 away from the air chamber 2 is provided with a flared mouth 11.

[0022] Through the above technical solution, the setting of the horn 11 can spread the water or paint sprayed from the spray pipe 1, thereby increasing the washing or painting range.

[0023] Preferably, the end of the air intake pipe 3 that connects to the air chamber 2 is a connecting end 33, and the connecting end 33 is tapered.

[0024] Through the above technical solution, the conical design of the connecting end 33 can pressurize the gas when it enters the gas chamber 2 through the air inlet pipe 3, thereby increasing the air pressure of the water or paint entering the liquid inlet pipe 4, and ensuring the pressure when it is sprayed from the spray pipe 1.

[0025] Preferably, the outer surface of the liquid inlet pipe 4 is provided with a handheld end 43.

[0026] The above technical solution allows the handheld terminal 43 to be convenient for workers to hold the device during work, thus improving work convenience.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
