For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0033] According to an embodiment of the utility model, a liquid pumping device is provided, comprising:

[0034] The water suction pipe 3 has a water inlet 8 and a water outlet at both ends, the water inlet 8 opens downward and is suitable for contacting the liquid to be pumped, and the water outlet is suitable for being connected to the water pump;

[0035] The limit block 5 is fixedly connected to one end of the water suction pipe 3 close to the water inlet 8. The limit block 5 is suitable for abutting against the ground to prevent the water inlet 8 from fitting against the ground.

[0036] The liquid pumping device provided in this embodiment extracts the liquid to be pumped through the water suction pipe 3, and is fixedly connected to the end of the water suction pipe 3 close to the water inlet 8 through the limit block 5, so that when the water inlet 8 is close to the ground, the limit block 5 abuts against the ground, thereby preventing the water inlet 8 from sticking to the ground under the action of the negative pressure inside it, and thus failing to absorb the liquid to be pumped.

[0037] Specifically, the construction flatness of the hardened site is difficult to control, and shallow water is easily formed on the surface of the site. For example, outdoor hardened sites will form more shallow water after rain. These water accumulations cannot be pumped out by conventional pumps, which will cause the road surface to be slippery and have certain safety risks, thus seriously affecting the normal use of the site. Pumps include gear pumps, centrifugal pumps, screw pumps, piston pumps, etc. The liquid inlet of the pump is connected to the water outlet of the suction pipe 3. When the pump is working, the inside of the suction pipe 3 is in a negative pressure state. At this time, the water inlet 8 is in contact with the liquid to be pumped, so that the liquid to be pumped is sucked into the suction pipe 3 and discharged through the pump. Preferably, the liquid outlet of the pump is connected to the liquid storage tank through a conduit, so as to be suitable for collecting and storing the extracted liquid through the liquid storage tank.

[0038] The limit block 5 includes a rod shape and a hemispherical shape, and the number of the limit block 5 includes at least one. When the water inlet 8 is close to the ground, along the direction of gravity, the bottom of the limit block 5 is located below the plane where the water inlet 8 is located, so that it is suitable for abutting against the ground through the limit block 5, so that there is a gap between the plane where the water inlet 8 is located and the ground, thereby preventing the water inlet 8 from being adsorbed and pressed against the ground under the action of negative pressure, thereby making it impossible to continue to suck the liquid to be pumped out.

[0039] In some embodiments, in combination Figures 1 to 4 As shown, the height of the limit block 5 is H, wherein 2mm≤H≤5mm.

[0040] Specifically, since the thickness of the limit block 5 is very thin, when the limit block 5 is in contact with the ground and the liquid level to be pumped is lower than the plane where the water inlet 8 is located, a small amount of liquid remains on the ground. The remaining liquid can be naturally dried after the liquid pumping device is removed, or the liquid pumping device can be left in place and the airflow generated by the suction force of the suction pipe 3 can be used to blow dry the remaining liquid.

[0041] In some embodiments, in combination Figures 1 to 4 As shown, an annular plate 4 is connected between the water suction pipe 3 and the limiting block 5, the inner peripheral wall of the annular plate 4 is fixedly connected to the outer peripheral wall of the water suction pipe 3, and the limiting block 5 is fixedly connected to the side of the annular plate 4 close to the ground.

[0042] Specifically, the plane where the annular plate 4 is located is perpendicular to the axis of the suction pipe 3. Preferably, the end face of the annular plate 4 close to the ground coincides with the plane where the water inlet 8 is located. There are multiple limit blocks 5, which are evenly distributed on the end face of the annular plate 4 close to the ground.

[0043] In some embodiments, in combination Figures 1 to 4 As shown, the density of the annular plate 4 is smaller than the density of the liquid to be pumped, so as to provide buoyancy to the suction pipe 3 .

[0044] The liquid pumping device provided in this embodiment provides buoyancy to the water suction pipe 3 through the annular plate 4 so that the water inlet 8 is located near the liquid surface of the liquid to be pumped. Compared with when the water inlet 8 is close to the ground, it has a larger pumping range, which is beneficial to improving the pumping efficiency.

[0045] Specifically, the density of the annular plate 4 is lower than the density of the liquid to be pumped. For example, the annular plate 4 is a foam plate. The annular plate 4 is suitable for providing buoyancy to the water suction pipe 3, and the buoyancy provided by the annular plate 4 is greater than the gravity of the limit block 5, so that when the liquid level of the liquid to be pumped is higher, the water inlet 8 floats near the liquid level of the liquid to be pumped. Compared with the position where the water inlet 8 is located close to the ground, it has a larger suction area, which is beneficial to improving the pumping efficiency of the liquid pumping device.

[0046] In some embodiments, in combination Figure 3 and Figure 4 As shown, a screen 7 is fixedly connected to the side of the annular plate 4 facing the ground, and the screen 7 covers the water inlet 8 to prevent debris in the liquid to be pumped from entering the water suction pipe 3.

[0047] The liquid pumping device provided in this embodiment is provided with a screen 7 on the annular plate 4, and the screen 7 covers the water inlet 8, thereby preventing debris in the liquid to be pumped from entering the water suction pipe 3 through the water inlet 8, thereby causing the water suction pipe 3 to be blocked.

[0048] Specifically, the number of the screen 7 includes at least one layer, and the screen 7 has multiple mesh holes to prevent the debris in the liquid from being sucked into the suction pipe 3 while allowing the liquid to pass through, thereby avoiding clogging of the suction pipe 3 and ensuring the continuity of liquid extraction.

[0049] In some embodiments, in combination Figures 1 to 4 As shown, the liquid pumping device also includes a curved pipe 2, one end of which is connected to the water outlet of the suction pipe 3, and the other end is connected to the water pump. The curved pipe 2 is suitable for changing the flow direction of the liquid.

[0050] Specifically, the curved pipe 2 can be a hard curved pipe or a soft curved pipe. By setting the curved pipe 2 to change the flow direction of the liquid, it is helpful to set the position of the water pump according to the environmental requirements of different sites, thereby improving the applicability of the liquid pumping device.

[0051] In some embodiments, in combination Figures 1 to 4 As shown, the liquid pumping device further comprises a support frame 1 , a curved pipe 2 is fixedly connected to the top of the support frame 1 , and the support frame 1 is suitable for supporting and fixing the curved pipe 2 .

[0052] Specifically, the support frame 1 includes a plurality of vertical poles 11 arranged at intervals, the axis of the vertical poles 11 is arranged at an angle to the horizontal direction, the support frame 1 also includes a cross bar 12 arranged at an angle to the vertical poles 11, the cross bar 12 is arranged between two adjacent vertical poles 11, and the two ends of the cross bar 12 are respectively fixedly connected to the two adjacent vertical poles 11. The structure is simple and easy to manufacture. As a preferred embodiment, at least one cross bar 12 is arranged between each two adjacent vertical poles 11, so as to ensure the structural stability of the support frame 1, wherein the elbow 2 is fixedly connected to the vertical poles 11 and / or the cross bar 12 in the area at the top of the support frame 1. As a feasible implementation form, a connecting plate is fixed on the outer peripheral wall of the elbow 2, and a through hole is opened on the connecting plate. The vertical poles 11 and / or the cross bar 12 are provided with threaded holes corresponding to the through holes. The elbow 2 is connected and fastened to the vertical poles 11 and / or the cross bar 12 by bolts penetrated through the through holes and the threaded holes. As an additional implementation form, the elbow 2 can also be directly tied to the top of the support frame 1 by a metal rope or a non-metal rope.

[0053] The vertical poles 11 and the horizontal poles 12 can be metal poles or non-metal poles. Preferably, the vertical poles 11 and the horizontal poles 12 are constructed from leftover steel bars at the construction site, that is, the support frame 1 is formed by welding steel bars, which is easy to manufacture and helps to reduce costs.

[0054] In some embodiments, in combination Figure 3 As shown, a roller 10 is provided at the bottom of the support frame 1 , and the support frame 1 is suitable for moving its position through the roller 10 .

[0055] The liquid pumping device provided in this embodiment is provided with a roller 10 at the bottom of the support frame 1 so as to facilitate the movement of the liquid pumping device as needed, which is beneficial to improving the mobility of the liquid pumping device.

[0056] Specifically, the roller 10 is disposed at the bottom of the vertical pole 11 . Preferably, the roller 10 is a universal wheel to facilitate the staff to move the position of the support frame 1 , thereby improving the moving efficiency of the support frame 1 .

[0057] In some embodiments, in combination Figures 1 to 4 As shown, the water suction pipe 3 includes a telescopic tube 31 , the top opening of the telescopic tube 31 is connected to the elbow 2 , the bottom opening of the telescopic tube 31 forms a water inlet 8 , and the telescopic tube 31 is suitable for changing the height of the water inlet 8 by its extension and retraction.

[0058] The liquid pumping device provided in this embodiment changes the height of the water inlet 8 by means of the telescopic tube 31 so as to be suitable for pumping liquids to be pumped out from pits of different depths, which is beneficial to improving the applicability of the liquid pumping device.

[0059] Specifically, the support frame 1 supports and fixes the bent pipe 2, and the top of the telescopic tube 31 is connected to the bent pipe 2, so the height of the top opening of the telescopic tube 31 remains unchanged, and the bottom opening of the telescopic tube 31 is configured as a water inlet 8. The material of the limit block 5 can be metal or non-metal, and the gravity of the limit block 5 and the annular plate 4 is greater than the force required for the telescopic tube 31 to extend, so that when the liquid level of the liquid to be pumped decreases, the telescopic tube 31 extends under the gravity of the limit block 5 and the annular plate 4, so that the position of the water inlet 8 decreases as the liquid level to be pumped decreases, thereby continuously sucking the liquid. Preferably, the telescopic tube 31 is a telescopic hose, so that after the position of the support frame 1 is fixed, the position of the telescopic tube 31 close to the ground can be manually moved to fine-tune the suction position. The water suction pipe 3 also includes a first connecting pipe 32, one end of which is connected to the liquid inlet of the curved pipe 2, and the other end is connected to the end of the telescopic pipe 31 away from the ground. The first connecting pipe 32 is suitable for connecting the curved pipe 2 and the telescopic pipe 31, wherein the first connecting pipe 32 can be a hard pipe or a soft pipe.

[0060] In some embodiments, in combination Figures 1 to 4 As shown, a flow guide pipe 9 is connected between the elbow 2 and the water pump.

[0061] Specifically, one end of the flow guide pipe 9 is connected to the liquid outlet of the elbow 2, and the other end is connected to the liquid inlet of the water pump. The flow guide pipe 9 is suitable for guiding the liquid into the water pump. A second connecting pipe 6 is also connected between the flow guide pipe 9 and the elbow 2. Preferably, the second connecting pipe 6 is a hose, so that the relative angle between the flow guide pipe 9 and the elbow 2 can be flexibly adjusted according to actual needs.

[0062] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present utility model are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations are all within the scope defined by the present utility model.
