[0003] Currently, vertical water pumps are commonly used. Vertical water pumps can not only drain water, but also discharge silt in the river. Vertical water pumps generally include a pipe body, a pump casing arranged below the pipe body, and a motor arranged above the pipe body. The pump casing is provided with an impeller, a water inlet and a water outlet. When in use, the water pump is tilted and fixed on the float so that the upper motor part is located on the water surface to prevent the motor from being immersed in water and malfunctioning.

[0004] With regard to the above-mentioned related technologies, vertical water pumps are generally heavy and need to be transported by a transport cart. After being transported to the site, the vertical water pump is removed from the cart and fixed to the float with tools. The float and the water pump are then transported to the river. The transportation and installation of the water pump are troublesome, time-consuming and labor-intensive. Summary of the Invention

The two positioning blocks are used to fix the water pump pipe body 101, and the two fixing blocks 33 are respectively arranged on the two first seat bodies 31. By rotating the first screw 321 to drive the first seat body 31 up and down, the water pump can be driven up and down; when transporting the water pump on the ground, the first seat body 31 and the water pump can be driven upward so that the lower surface of the water pump is higher than the lower surface of the driving wheel 13, thereby pushing the water pump for transportation; when draining in the river channel, the first screw 321 can be rotated to move the water pump downward to a suitable position for water suction and drainage.

[0048] Reference Figure 3 and Figure 4In this embodiment, the second seat body 35 can be a rectangular seat body, and the second seat body 35 is slidably set on the upper surface of the second plate 312. The two second driving members 34 are respectively used to drive the two second seat bodies 35 to move in the direction of approaching or moving away from the corresponding first plate 311.

The second guide rod 342 slides through the first plate 311, and the second guide rod 342 can be respectively arranged on both sides of the second screw 341, so as to rotate the second screw 341, and the second screw 341 moves in a direction perpendicular to the first plate 311, which can drive the second base body 35 to move back and forth along the length direction of the second screw 341, and finally drive the two fixed blocks 33 to approach or move away from each other.

[0049] Reference Figure 4 and Figure 5 In this embodiment, a first limit block 351 is fixed on the lower surface of the second seat body 35 for limiting the upward movement of the second seat body 35 relative to the second plate 312. The first limit block 351 is a "T"-shaped block. In other embodiments, the first limit block 351 may also be a dovetail block. A first limit groove 3121 for sliding of the first limit block 351 is provided on the upper surface of the second plate 312. The extension direction of the first limit groove 3121 is parallel to the sliding direction of the second seat body 35. One first limit block 351 can be set on the lower surface of the second seat body 35. In other embodiments, two first limit blocks 351 can also be set, and the first limit groove 3121 is opened corresponding to the second limit block 371.

[0050] Reference Figure 4 and Figure 5 In this embodiment, a fixing block 33 is slidably mounted on the sidewall of the second base 35 facing away from the second plate 312. The fixing block 33 can be a rectangular block. Two parallel positioning rings 102 are fixed to the sidewall of the water pump tube 101 at intervals along the length of the water pump tube 101. The fixing block 33 can be inserted between the two positioning rings 102, thereby clamping the water pump tube 101 and fixing the water pump. A clamping groove 332 for clamping the water pump tube 101 is formed on the sidewall of the two fixing blocks 33 adjacent to each other. When the sidewalls of the two fixing blocks 33 abut each other, the sidewall of the clamping groove 332 can be pressed against the sidewall of the water pump tube 101.

[0051] Reference Figure 5 and Figure 6In this embodiment, a limiting member 37 is provided between the second base body 35 and the fixed block 33 to limit the horizontal movement of the fixed block 33 relative to the second base body 35. The limiting member 37 may be a second limiting block 371 fixed to the side wall of the fixed block 33 facing the second base body 35. The second limiting block 371 may have a T-shaped cross section, and a second limiting groove 353 is defined on the side wall of the second base body 35 for the second limiting block 371 to slide up and down. In other embodiments, the second limiting block 371 may also be fixed to the side wall of the second base body 35, and the second limiting groove 353 is defined on the side wall of the fixed block 33.

[0052] Reference Figure 5 and Figure 6 In this embodiment, the third driving member 36 is used to drive the fixed block 33 to move up and down. Specifically, the third driving member 36 includes a driving disk 361 that is rotatably disposed within the positioning seat, a driving block 362 disposed on the driving disk 361, and a power source 363 for driving the driving disk 361 to rotate. The driving disk 361 is a circular disk, the axis of which is perpendicular to the side wall of the second seat body 35 facing the fixed block 33. The driving block 362 has a circular cross-section and is located on the side of the driving disk 361 facing the fixed block 33. The power source 363 can drive the driving disk 361 to rotate along the axis, thereby driving the driving block 362 to move along a circular trajectory. The end of the driving block 362 away from the driving disk 361 extends out of the surface of the second seat body 35. The second seat body is provided with a circular clearance groove 352 for the driving block 362 to rotate.

[0053] A waist-shaped groove 331 for the driving block 362 to be inserted into is provided on the side wall of the fixed block 33 facing the second seat body 35. The waist-shaped groove 331 extends in the horizontal direction. When the driving block 362 moves in a circle under the drive of the driving disk 361, the driving block 362 slides in the waist-shaped groove 331 at the same time. The fixed block 33 moves up and down repeatedly with the cooperation of the second limit block 371 and the second limit groove 353, and driven by the driving disk 361, thereby driving the water pump to move up and down.

[0054] Reference Figure 5 and Figure 63633 is provided in the second seat body 35 and is connected to the worm gear 3632; a space is provided in the second seat body 35 for the worm gear 3632 and the worm gear 3631 to rotate; in order to achieve a better waterproof effect, the drive motor 3633 can be battery-driven and controlled by a signal; when the water pump encounters silt blocking the pipe during drainage, the drive motor 3633 can be started to drive the worm gear 3632 to rotate, thereby driving the drive disc 361 to rotate, and finally driving the fixed block 33 and the water pump to move up and down, so that the water inlet pipe below the water pump can discharge the silt, thereby playing the role of a through hole and reducing blockage.

[0055] The implementation principle of a water pump bracket for river drainage in the embodiment of the present application is as follows: when transporting the water pump on the ground, first rotate the two second screws 341 respectively to drive the two fixing blocks 33 closer to each other and insert them into the two positioning rings 102 on the water pump pipe body 101, thereby fixing the water pump; then rotate the two first screws 321 to move the water pump upward so that the lower surface of the water pump is higher than the driving wheel 13; then the outer support frame 11 can be dragged to transport the water pump. When a water pump is needed to drain the river, the water pump bracket and the water pump can be pushed into the river through the outer support frame 11. The suspension cylinder 21 allows the water pump to float on the water surface. Then, rotate the two first screws 321 to adjust the water pump downward to the appropriate position, and then water can be pumped through the water pump.
