[0003] For example, a patent named: Horizontal Self-Priming Centrifugal Pump (patent application number: CN200820186092.7) discloses a horizontal self-priming centrifugal pump, wherein an annular gap is provided between the pump body and the volute body, so that the water inlet flow channel is communicated with the gas-liquid separation chamber, and the liquid in the gas-liquid separation chamber enters the water inlet flow channel in the form of a jet. During the self-priming and exhausting stage, these liquids are quickly mixed with the air in the water inlet flow channel and enter the impeller, thereby accelerating the pumping speed and improving the suction capacity of the pump. However, the above-mentioned self-priming pump is not convenient for autonomous movement and transportation. When it is transferred to the use location, it needs to be moved by external transportation equipment, which increases the cost, is time-consuming and labor-intensive, and reduces the practicality of the self-priming pump.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figures 1 to 5 A horizontal self-priming pump is shown, comprising a frame 1, with a pump body 2 fixedly mounted on the top of the frame 1. The pump body 2 comprises a pump casing, a motor, an impeller and other structures. The main part of the pump body 2 is placed horizontally with the ground and is horizontally distributed. It has the characteristics of compact structure, small footprint, easy assembly and disassembly, and simple maintenance. Its working principle is to use a motor to drive the impeller to rotate, so that it generates centrifugal force, so that the liquid generates kinetic energy, thereby achieving water pumping or water supply. Specifically, when the pump body 2 is started, water is sucked into the pump through the gap between the pump casing and the impeller, and then the water is brought to the water outlet due to the action of centrifugal force, thereby achieving the water delivery effect. The pump body 2 and its working principle are existing common technologies and will not be described in detail here.

[0023] Considering that the pump body 2 is not convenient to move and transport independently, when it is transferred to the use location, it needs to be moved by external transportation equipment. At the same time, the main part of the pump body 2 is placed horizontally with the ground, so that its center of gravity is lower, which increases the difficulty of transfer. Grooves 3 are provided on both sides of the bottom of the frame 1, and square grooves 4 are opened at both ends of the top of the groove 3. The inside of the square groove 4 is slidingly connected with a slide post 5, and the bottom of the slide post 5 is rotatably connected with a universal wheel 6. The slide post 5 slides downward inside the square groove 4, and the universal wheel 6 extends from the inside of the groove 3 to facilitate the movement of the pump body 2; and considering that it is only in contact with the ground through the universal wheel 6, it is easy to shake due to the small contact area. When the pump body 2 is running, the slide post 5 slides upward inside the square groove 4, and the universal wheel 6 is recovered to the inside of the groove 3. The frame 1 as a whole directly contacts the ground, thereby improving the stability of the pump body 2 when used.

[0024] In order to make the two sliding posts 5 on the same side move synchronously, an upper connecting plate 8 is fixedly connected between the tops of the two sliding posts 5 , and a control component for driving the upper connecting plate 8 to move up and down is provided above the groove 3 .

[0025] In the specific setting, the control component includes a threaded rod 9 and a rotating rod 10. The threaded rod 9 is rotatably connected to the top of the frame 1. A threaded hole that cooperates with the threaded rod 9 is opened on the upper connecting plate 8, and the rotating rod 10 is fixedly connected to the top of the threaded rod 9.

[0026] When transfer is required, the threaded rod 9 is rotated by the rotating rod 10. Since the upper connecting plate 8 is provided with a threaded hole that matches the threaded rod 9, and under the limiting effect of the square groove 4 and the sliding column 5, the upper connecting plate 8 drives the two sliding columns 5 to move downward synchronously, and the universal wheel 6 extends from the inside of the groove 3, facilitating the movement of the pump body 2;

[0027] When the pump body 2 is running, the threaded rod 9 is rotated in the opposite direction by the rotating rod 10. Since the upper connecting plate 8 is provided with a threaded hole that cooperates with the threaded rod 9, and under the limiting action of the square groove 4 and the sliding column 5, the upper connecting plate 8 drives the two sliding columns 5 to move upward synchronously, and the universal wheel 6 is recovered to the inside of the groove 3. The frame 1 as a whole is in direct contact with the ground, thereby improving the stability of the pump body 2 during use.

[0028] During specific use, a driving device can be provided to cooperate with the threaded rod 9, including a motor and other structures to realize electric control, or a transmission structure can be added to make the threaded rods 9 on both sides rotate synchronously. The driving device and the transmission structure are both existing common technologies and will not be elaborated here.

[0029] A lower connecting plate 7 is fixedly connected between the bottoms of the two sliding columns 5 , and the lower connecting plate 7 is provided to improve the stability of the sliding columns 5 when moving up and down.

[0030] To further enhance the stability of the pump body 2, air cavities 13 are formed on both sides of the frame 1. A circular groove 14 is formed through the bottom of the air cavity 13. Multiple circular grooves 14 are provided, and the multiple circular grooves 14 are evenly spaced. A slide rod 15 is slidably connected to the interior of the circular groove 14, and a pointed cone 16 is fixedly connected to the bottom of the slide rod 15. The pointed cone 16 is provided to facilitate insertion into the ground. When the slide rod 15 and the pointed cone 16 extend from the interior of the circular groove 14, they penetrate the ground, making the frame 1 less likely to shake.

[0031] To control the extension and retraction of slide bar 15 and pointed cone 16, a connecting assembly is provided between air cavity 13 and the corresponding lower connecting plate 7. The connecting assembly includes an airbag 11 and a gas channel 12. Airbag 11 is fixedly connected between lower connecting plate 7 and the top of groove 3. Gas channel 12 is provided inside frame 1. One end of gas channel 12 is connected to airbag 11, and the other end is connected to air cavity 13.

[0032] When transferred to the destination position, the upper connecting plate 8 drives the two sliding columns 5 to move upward synchronously, and the universal wheel 6 is recovered to the inside of the groove 3. During this process, the lower connecting plate 7 moves upward and compresses the airbag 11, and the gas inside it is transported to the inside of the circular groove 14 through the gas channel 12 and the air cavity 13, so that the sliding rod 15 and the pointed cone 16 extend from the inside of the circular groove 14 and insert into the ground. The frame 1 is not easy to shake, which further improves the stability of the pump body 2 during use.

[0033] When the pump body 2 needs to be transferred, the upper connecting plate 8 drives the two slide columns 5 to move downward synchronously, and the universal wheel 6 extends from the inside of the groove 3. During this process, the lower connecting plate 7 moves downward and stretches the airbag 11, and the gas inside the circular groove 14 is sucked through the gas channel 12 and the air cavity 13, so that the slide rod 15 and the pointed cone 16 are recovered to the inside of the circular groove 14, which does not affect the transfer of the pump body 2.
