[0033] The working principle and technical effects of the above technical solution are:

[0034] In the self-priming pump, the pump base 2 is arranged at the bottom of the self-priming pump body 1 to support the self-priming pump body 1, facilitating overall carrying and moving. Four inclined slide pipe 4 are arranged in the installation chamber of the pump base 2, and four walking support wheel groups 5 are slidably arranged in the four inclined slide pipes 4. When carrying and moving is needed, the four walking support wheel groups 5 can be controlled by the control mechanism 6 to move from the four inclined slide pipes 4 to the four side openings 3, and then extend out of the four side openings 3 to contact the ground, so that the pump base 2 is separated from the ground, facilitating moving. When the four walking support wheel groups extend out, the height of the pump base 2 and the self-priming pump body 1 is raised. In order to improve the stability of the self-priming pump body 1 after being raised, the inclined slide pipe 4 is used to guide the extension direction of the walking support wheel group 5. The horizontal height of the end of the inclined slide pipe 4 connected with the side opening 3 is lower than the horizontal height of the end of the inclined slide pipe 4 away from the side opening 3, so that the longer the length of the four walking support wheel groups extending out, the larger the support range, and the better the stability.

When the I-shaped slide 601 slides downward, the four walking support wheel groups 5 are driven by the lateral sliding ways 603 on both sides of the I-shaped slide 601 to move downward in the inclined sliding grooves on the side of the four inclined sliding pipe 4, and when the four lateral sliding columns 502 slide downward, the four supporting arms 501 and the four walking wheels 503 are extended to the outside of the four side openings 3, and are supported on the ground by the four walking wheels 503, so that the whole device is moved conveniently. When the I-shaped slide 601 slides upward, the four walking support wheel groups 5 are driven by the lateral sliding ways 603 on both sides of the I-shaped slide 601 to move upward in the inclined sliding grooves on the side of the four inclined sliding pipe 4, so that the four supporting arms 501 and the four walking wheels 503 are retracted into the four inclined sliding pipe 4, so that the device is fixed conveniently. The control motor 605 is electrically connected with the rechargeable battery group installed in the pump seat 2 mounting chamber, so that power supply is facilitated.
