Description

Technical Field

[0001] The utility model relates to an antifreeze high-pressure water pump for severe cold environments, in particular to an antifreeze high-pressure water pump for severe cold environments applied in the field of pump equipment. Background Art

[0002] The most widely used high-pressure water pump should be the micro high-pressure water pump. Because of its high pressure, small size, easy to carry, and can be driven by a car battery, it is often used for cleaning, spraying, spraying, pressurization, pumping, etc. Various micro water pumps and micro self-priming water pumps can be found in Chengdu Xinweicheng Technology. The existing high-pressure water pumps have the phenomenon of poor operation when used in low-temperature areas due to low temperatures, which affects the efficiency of the pump.

[0003] In order to solve the problem that the existing high-pressure water pumps do not operate properly when used in low-temperature areas, affecting the efficiency of the pump, the antifreeze high-pressure water pumps on the market adopt a design in which an antifreeze mechanism is set inside, which has a certain market share.

[0004] The antifreeze type high-pressure water pumps currently on the market use an antifreeze mechanism inside the pump to solve the problem of the high-pressure water pump body being frozen. However, there is no antifreeze mechanism in the external pipeline, and the output water flowing into the pipeline will still freeze and expand in the opposite direction, contacting the pump and causing the pump to explode. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that the antifreeze type high-pressure water pump in the existing market has no antifreeze mechanism in its external pipe, and the output water flowing into the pipe will still freeze and expand in the reverse direction, and come into contact with the pump machine, causing the pump machine to explode.

[0006] In order to solve the above problems, the utility model provides an antifreeze high-pressure water pump for severe cold environments, including a pump installed on a base, the output end and the input end of the pump are fixedly connected to water pipes, the outer end of the water pipe is provided with a telescopic sleeve, the inner side wall of the telescopic sleeve is fixedly connected to a thermal insulation liner, the end of the telescopic sleeve close to the pump is fixedly connected to a connecting hoop, and the connecting hoop is sleeved outside the interface between the water pipe and the pump, the end of the connecting hoop away from the pump is fixedly connected to a self-controlling temperature mixing thermal elastic kit belt, and the self-controlling temperature mixing thermal elastic kit belt is sleeved outside the water pipe.

[0007] In the above-mentioned antifreeze high-pressure water pump for severe cold environments, this solution effectively avoids the risk of the output water freezing and expanding in the reverse direction when there is no antifreeze mechanism in the external pipeline, and the risk of the output water coming into contact with the pump and causing the pump to explode, by arranging a telescopic sleeve with antifreeze function in the water pipe outside the output end of the pump and the input pipe.

[0008] As a further improvement of the present application, an outer hoop ring is fixedly connected to one end of the telescopic sleeve away from the pump, and a connecting threaded ring is fixedly connected to one end of the telescopic sleeve close to the pump.

[0009] As a further improvement of the present application, the right end and the upper end of the pump are fixedly connected with a threaded retaining ring, and the threaded retaining ring is located outside the output end and the input end of the base, and the threaded retaining ring is threadedly connected to the pump through the threaded retaining ring.

[0010] As a further improvement of the present application, a pair of elastic draw cords are fixedly connected to one end of the outer hoop away from the pump.

[0011] As another improvement of the present application, the outer end of the telescopic sleeve is fixedly connected to a plurality of pairs of binding ropes, and the plurality of pairs of binding ropes are arranged at equal distances.

[0012] As another improved supplement of the present application, the outer end of the binding rope is bound with thickened thermal insulation cotton, and the thickened thermal insulation cotton is located outside the telescopic sleeve.

[0013] In summary, this solution effectively avoids the risk of the output water freezing and reverse expansion in the water pipe when there is no antifreeze mechanism in the external pipeline, and the risk of the pump bursting when it contacts the pump and causes the pump to burst. The self-controlling temperature-mixing thermal elastic kit belt sleeve arranged in the telescopic sleeve is installed outside the water pipe, and the stretching state of the telescopic sleeve can be adjusted according to the actual length of the water pipe, so that the application scope of the telescopic sleeve is wider, and the antifreeze ability of the telescopic sleeve is enhanced in colder environments.

[0020] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0021] The first implementation method:

[0022] Figure 2-3 It is shown that the pump 2 is installed on the base 1, and the output end and the input end of the pump 2 are fixedly connected to the water pipe 6, the outer end of the water pipe 6 is provided with a telescopic sleeve 4, the inner wall of the telescopic sleeve 4 is fixedly connected to the thermal insulation liner 8, the end of the telescopic sleeve 4 close to the pump 2 is fixedly connected to the connecting hoop 5, and the connecting hoop 5 is sleeved outside the interface between the water pipe 6 and the pump 2, and the end of the connecting hoop 5 away from the pump 2 is fixedly connected to the self-controlling temperature mixing thermal elastic kit belt 7, and the self-controlling temperature mixing thermal elastic kit belt 7 is sleeved outside the water pipe 6.

[0023] Figure 2 It is shown that the end of the telescopic sleeve 4 away from the pump 2 is fixedly connected to an outer hoop ring 9, the end of the telescopic sleeve 4 close to the pump 2 is fixedly connected to a connecting threaded ring 3, the right end and the upper end of the pump 2 are fixedly connected to threaded clamps, and the threaded clamps are located outside the output end and the input end of the base 1, the connecting threaded ring 3 and the pump 2 are threadedly connected via the threaded clamps, and the end of the outer hoop ring 9 away from the pump 2 is fixedly connected to a pair of elastic pull ropes 10.

[0024] Figure 1-3 It is shown that the present solution arranges a telescopic sleeve 4 with an antifreeze function between the output end of the pump 2 and the water pipe 6 outside the input pipe. The telescopic sleeve 4 is threadedly installed outside the water pipe 6, which effectively avoids the risk that the output water flowing into the water pipe 6 will still freeze and expand in the opposite direction if there is no antifreeze mechanism in the external pipeline, and contact with the pump 2 will cause the pump 2 to burst. The self-controlling temperature-mixing thermal elastic kit belt 7 arranged in the telescopic sleeve 4 is arranged outside the water pipe 6, and the stretching state of the telescopic sleeve 4 can be adjusted according to the actual length of the water pipe 6, so that the application range of the telescopic sleeve 4 is wider, and a thermal insulation liner 8 is arranged in the telescopic sleeve 4. The thermal insulation liner 8 assists in antifreeze and cold resistance. At the same time, an elastic pull rope 10 is arranged on the side of the outer hoop 9, and the elastic pull rope 10 can be wrapped and bound with the valve to play a preliminary positioning role.

[0025] The second implementation method:

[0027] Figure 4 It is shown that a plurality of binding ropes 11 are arranged outside the telescopic sleeve 4 at the same time. The binding ropes 11 can bind the thickened thermal insulation cotton outside the telescopic sleeve 4, thereby enhancing the anti-freezing ability of the telescopic sleeve 4 in a colder environment.

[0028] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
