[0017] 1. The pumping device for removing rainwater in sections is provided with a water collecting box, a first pipe, a second pipe, a suction cup, an elastic plug, a first transverse plate and a second transverse plate. A vacuum generator is used to form a negative pressure environment inside the first pipe, the second pipe and the water collecting box.

[0019] 3. The pumping device for removing rainwater in sections is provided with a filter box, a box body, a water pipe and a water pump. When the water in the water collecting box is discharged into the filter box, the water pump is started to pump part of the water in the filter box into the box body, and the weight of the box body is increased, so that the first transverse plate and the second transverse plate can be reset, so that the elastic plug can block the first drainage pipe again, and the vacuum generator can be restarted, and the drainage operation of the hull steel plate can be carried out again;

[0020] 4. The pumping device for removing rainwater in sections is provided with a coarse sand layer, a fine sand layer and an activated carbon adsorption layer, which can filter out particulate impurities and odors in the water entering the filter box, thereby recycling the water, for example, it can be used to flush the floor of a processing workshop, etc. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-2 A pumping device for removing rainwater in sections includes a water collecting box 1, a vacuum generator 2 is installed above the water collecting box 1, and a first water inlet pipe 3 is connected to the water collecting box 1 at a position on one side of the vacuum generator 2 above the water collecting box 1, a first drain pipe 13 is connected to the water collecting box 1 below, a first pipe 4 is arranged inside the water collecting box 1 below the vacuum generator 2, a second pipe 5 is sleeved on the outside below the first pipe 4, the first pipe 4 and the second pipe 5 are slidably connected, and a suction cup 8 is connected to one end of the second pipe 5.

[0030] Reference Figure 1-5, the first pipe 4 and the second pipe 5 are slidably connected, and a second water inlet pipe 6 is connected to one side of the upper end of the second pipe 5. A hard sealing sleeve 9 is arranged at the position corresponding to the second pipe 5 below the water collecting box 1, and a soft sealing sleeve 10 is fixed inside the hard sealing sleeve 9. The hard sealing sleeve 9 can be made of metal, such as stainless steel, and the soft sealing sleeve 10 can be made of rubber. A notch 11 is opened on the surface of the second pipe 5 near the soft sealing sleeve 10. When the suction cup 8 is adsorbed on the bottom of the water collecting box 1, the hard sealing sleeve 9 and the soft sealing sleeve 10 seal the notch 11 to prevent water in the water collecting box 1 from entering the second pipe 5 from the notch 11, thereby avoiding destroying the negative pressure environment of the second pipe 5. An elastic plug 14 is arranged inside the first drain pipe 13. The elastic plug 14 is a component made of rubber material, and the weight of the elastic plug 14 is greater than the weight of the box body 21. The lower end of the elastic plug 14 is fixed with a first The cross plate 15, one end of the first cross plate 15 is slidably connected to the second cross plate 19. The purpose of this arrangement is that when the suction cup 8 no longer adsorbs the bottom of the water collecting tank 1, the end of the elastic plug 14 in the first cross plate 15 and the second cross plate 19 can be rotated downward, so that the elastic plug 14 no longer blocks the first drain pipe 13, and the water in the water collecting tank 1 can be discharged from the first drain pipe 13. A first connecting member 16 is fixed to one end of the first cross plate 15, and a second connecting member 17 is fixed at a position corresponding to the first connecting member 16 on the surface of the suction cup 8. The first connecting member 16 and the second connecting member 17 are rotatably connected by a first pin shaft 18. A fixing rod 20 is fixed at a position corresponding to the second cross plate 19 below the water collecting tank 1, a box body 21 is installed at the upper end of the second cross plate 19, and the second cross plate 19 and the fixing rod 20 are rotatably connected by a second pin shaft, and a second drain pipe 22 is connected to the lower end of one end of the box body 21.

[0031] Reference Figure 2-3 A waterproof breathable membrane 12 is fixed to the interior of the second pipe 5 at a position below the notch 11. The waterproof breathable membrane 12 can prevent water from entering the lower section of the second pipe 5, thereby preventing all water in the second pipe 5 from being discharged from the notch 11. A filter screen 7 is installed at the water inlet end of the second water inlet pipe 6. The filter screen 7 is a component made of stainless steel. The filter screen 7 can prevent impurities in the water from entering the second pipe 5 from the second water inlet pipe 6, thereby avoiding blockage of the second pipe 5.

[0032] Reference Figure 4 and Figure 6A filter box 23 is arranged below the water collecting box 1, and a mesh box 24 is installed above the interior of the filter box 23. The interior of the mesh box 24 is provided with a coarse sand layer 26, a fine sand layer 27 and an activated carbon adsorption layer 28 from top to bottom. The water discharged from the water collecting box 1 is filtered through the coarse sand layer 26, the fine sand layer 27 and the activated carbon adsorption layer 28 in turn, and particulate impurities and odors can be filtered out, so that the water can be recycled. For example, it can be used for flushing the floor of a processing workshop, etc. Handles 29 are fixed above both ends of the mesh box 24, and the edges of the handles 29 are provided with rounded corners. A support frame 25 is fixed inside the filter box 23, and reinforcing ribs are provided at the inner corners of the support frame 25. This structure facilitates the installation and disassembly of the mesh box 24. After the device has been used for a period of time, the coarse sand layer 26, the fine sand layer 27 and the activated carbon adsorption layer 28 can be replaced conveniently.

[0033] Reference Figure 1 A third drainage pipe 30 is connected to the lower part of one end of the filter box 23, and a water delivery pipe 31 is connected to one end of the filter box 23 at a side position of the third drainage pipe 30. A water pump 32 is installed at the water inlet end of the water delivery pipe 31, and the water outlet end of the water delivery pipe 31 is located above the box body 21. The water pump 32 and the filter box 23 are fixedly connected by a fixing frame 33. When the water in the water collecting box 1 is drained, the water pump 32 is started again to pump part of the water in the filter box 23 into the box body 21, thereby increasing the weight of the box body 21 so that the weight of the box body 21 is greater than the total weight of the elastic plug 14 and the suction cup 8. Then, the first cross plate 15 and the second cross plate 19 are reset, so that the elastic plug 14 blocks the first drainage pipe 13 again, and the vacuum generator 2 is restarted to form a negative pressure environment between the water collecting box 1, the first pipe 4 and the second pipe 5, and then the drainage operation of the hull steel plate can be carried out again.

[0034] Reference Figure 1 A fixing plate 34 is fixed on both sides of the water collecting box 1, and the filter box 23 is fixedly connected to the fixing plate 34 through a first supporting plate 35. A second supporting plate 36 is fixed to the lower end of the fixing plate 34, and self-locking wheels 37 are installed at both ends below the second supporting plate 36. The setting of the self-locking wheel 37 makes it convenient to move and stably place the device.

[0035] In the present invention, the vacuum generator 2 is first started to allow the suction cup 8 to be adsorbed on the bottom of the water collecting tank 1, and the second pipe 5, the first pipe 4 and the interior of the water collecting tank 1 form a negative pressure environment. The water inlet end of the first water inlet pipe 3 can be connected to a hose, and the water inlet end of the hose is connected to the hull steel plate to be drained, so that the water on the steel plate can be pumped into the water collecting tank 1. When the water level in the water collecting tank 1 rises to the position of the second water inlet pipe 6, the water will enter the second pipe 5 through the second water inlet pipe 6, destroying the second pipe. 5 and the negative pressure environment of the suction cup 8, so that the suction cup 8 no longer adsorbs the bottom of the water collecting box 1, and because the weight of the elastic plug 14 is greater than the weight of the box body 21, the first cross plate 15 and the second cross plate 19, where the elastic plug 14 is located, can be rotated downward, so that the elastic plug 14 no longer blocks the first drain pipe 13, and the water in the water collecting box 1 can be discharged from the first drain pipe 13 and enter the filter box 23. At the same time, one end of the first cross plate 15 drives the suction cup 8 and the second pipe 5 to move downward, and as the first cross plate 15 and the second cross plate 19 are connected, the suction cup 8 and the second pipe 5 are connected. When the second pipe 5 moves downward, the notch 11 is no longer in the same position with the soft sealing sleeve 10 and the hard sealing sleeve 9, and the water in the second pipe 5 can be discharged from the notch 11. When the water in the water collecting box 1 is completely discharged, the water pump 32 is started again to pump part of the water in the filter box 23 into the box body 21, increasing the weight of the box body 21 so that the weight of the box body 21 is greater than the total weight of the elastic plug 14 and the suction cup 8. Then, the first cross plate 15 and the second cross plate 19 are reset, so that the elastic plug 14 is again connected to the first row. After the water pipe 13 is blocked and the vacuum generator 2 is restarted to form a negative pressure environment in the water collecting box 1, the first pipe 4 and the second pipe 5, the drainage operation of the hull steel plate can be performed again. After the device performs a new round of pumping operation, the water in the filter box 23 and the box body 21 can be discharged from the third drainage pipe 30 and the second drainage pipe 22 respectively. In order to facilitate the observation of the water level changes of the water collecting box 1 and the filter box 23, an observation window (not shown in the figure) can be set on one side of the water collecting box 1 and the filter box 23;

[0036] The water discharged from the water collecting tank 1 can be filtered when entering the filter box 23. The coarse sand layer 26 can filter larger particle impurities in the water, and the fine sand layer 27 can filter smaller particle impurities in the water. Finally, after being adsorbed by the activated carbon adsorption layer 28, the odor in the water is removed, and the water can be recycled and used for flushing the floor of the processing workshop, etc.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
