Description

Technical Field

[0001] The utility model relates to the technical field of submersible pumps, in particular to a sand-proof self-adjusting floating water-absorbing device. Background Art

[0002] Submersible pumps are important equipment for water supply and drainage. When in use, the entire unit is submerged in water to extract groundwater to the surface. Existing submersible pumps are widely used and have a strong overall water absorption capacity, making them easy for staff to use.

[0003] In the Chinese patent with publication number CN220622207U, a new type of sand-proof submersible pump is mentioned, which has a sand-proof mechanism with good sand-proof effect, so that the submersible pump can work normally, thereby improving the use efficiency and effect of the submersible pump; it includes a pump group body, a first connecting plate, a second connecting plate and multiple groups of bolts, the middle part of the top end of the first connecting plate is connected to the bottom end of the pump group body, the bottom end of the first connecting plate and the top end of the second connecting plate are fastened and connected by multiple groups of bolts, and the bottom area of ​​the pump group body is provided with a sand-proof mechanism; the sand-proof mechanism also includes a double-layer sand-proof sleeve, a support plate, a fixed plate, a sliding plate, a limit rod, a cleaning sleeve, a first screw and a servo motor, a working chamber is provided in the double-layer sand-proof sleeve, the bottom end of the second connecting plate is connected to the top end of the double-layer sand-proof sleeve, the outer end of the fixed plate is connected to the top area of ​​the working chamber, the top end of the support plate is connected to the bottom end of the double-layer sand-proof sleeve, and the bottom end of the support plate is provided with a supporting mechanism.

[0004] However, the above technical solution drives the cleaning sleeve to slide back and forth up and down through the driving device, so that the cleaning sleeve scrapes off the sand and gravel attached to the double-layer anti-sand sleeve. Although this device can prevent the water suction port from being blocked, submersible pumps are mostly used in deeper waters, making it difficult to repair the driving structure after it is damaged, and then it is difficult to continue to prevent blockage, resulting in the anti-blockage effect of the device being relatively general, which needs to be improved by the staff.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1 and Figure 2 As shown, the utility model provides a sand-proof self-adjusting floating water-absorbing device, comprising:

[0034] A submersible pump body 1 is provided with a sealed cabin 2 on the water suction port of the submersible pump body 1, and a water suction pipe 3 is connected to the side of the sealed cabin 2.

[0035] A floating member 4 is connected to one end of the water suction pipe 3 close to the water inlet end. The floating member 4 can be affected by the buoyancy in the water body and can drive the water inlet end of the water suction pipe 3 to float upward in the water body.

[0036] A water inlet bottom valve 5 is installed at the water inlet end of the water suction pipe 3. The water inlet bottom valve 5 has a one-way cut-off function to prevent water backflow inside the submersible pump body 1. A filter screen 6 is arranged on the water inlet end of the water inlet bottom valve 5. The filter screen 6 intercepts larger impurities outside the water inlet end of the water inlet bottom valve 5. At the same time, the filter screen 6 is made of rigid stainless steel to avoid deformation of the filter screen 6 when impacted by water flow.

[0037] When in use, the submersible pump body 1 is placed in a deep water area. The floating part 4 is affected by the buoyancy of the water body. The floating part 4 drives the water inlet end of the suction pipe 3 to move upward away from the water bottom and suspend in the water body. Therefore, when the submersible pump body 1 falls on the bottom of the water and the submersible pump body 1 starts to absorb water, the water inlet end of the suction pipe 3 can be prevented from directly contacting the silt and impurities at the bottom of the water, thereby sucking the silt and impurities into the submersible pump body 1 to avoid blockage of the pipes inside the submersible pump body 1.

[0038] Among them, the suction pipe 3 moves upward and the distance between it and the submersible pump body 1 is limited by the length of the suction pipe 3. For water bodies of different depths or water bodies with more bottom silt and impurities, suction pipes 3 and floating parts 4 of different lengths can be assembled, so as to flexibly adjust the suspension height of the floating part 4 in the water body, and further avoid the water inlet end of the suction pipe 3 from contacting with silt and impurities.

[0039] Furthermore, during the startup of the submersible pump body 1 , water enters the water suction pipe 3 through the filter screen 6 and the water inlet bottom valve 5 , and further filtration by the filter screen 6 can further intercept impurities to protect the pipeline inside the submersible pump body 1 .

[0040] In order to enable the floating member 4 to arbitrarily pull the pipe head of the water suction pipe 3 to move, the water suction pipe 3 needs to have a certain flexibility. Figure 2 As shown, the water suction pipe 3 includes a connecting pipe 301 fixedly connected to the water inlet of the side wall of the sealed cabin 2, the connecting pipe 301 is connected to a rigid water inlet pipe 302, the rigid water inlet pipe 302 is connected to a hose 303, and the hose 303 is connected to a floating pipe head 304.

[0041] The hose 303 is flexible so that the floating tube head 304 can be moved by the floating member 4. Furthermore, the hose 303 is made of a stainless steel braided hose to prevent the hose 303 from being squeezed during the water absorption process.

[0042] The floating member 4 is fixedly disposed on the floating tube head 304 .

[0043] In this embodiment, the water inlet end of the rigid water inlet pipe 302 is upward, and the water inlet end of the floating pipe head 304 is downward, so the path of water entering the submersible pump body 1 is arched. Under the action of gravity, the silt in the water body increases the difficulty of the silt in the water body entering the water suction pipe 3, so that the silt in the water body spontaneously settles in the process of entering the water suction pipe 3, reducing the probability of silt entering the water suction pipe 3.

[0044] In this embodiment, refer to Figure 3 As shown, the floating member 4 includes a bracket 401 with a sleeve hole 402, the sleeve hole 402 is sleeved on the floating pipe head 304, and a bearing plate 403 is connected to both ends of the bracket 401. A bladder 404 that can float upward in the water body is attached to the bearing plate 403.

[0045] The bladder 404 has a low density, so that the bladder 404 is subjected to a large buoyancy in the water body, so that the floating member 4 can drive the floating tube head 304 to move upward and suspend in the water body.

[0046] In this embodiment, the bladder 404 is located at the bottom of the supporting plate 403 , so the bladder 404 supports and drives the floating tube head 304 to move, thereby reducing the risk of the bladder 404 being separated from the supporting plate 403 .

[0047] In this embodiment, the capsule 404 is an airbag filled with low-density gas.

[0048] Specifically, depending on the use environment, for example, for water bodies in complex environments that may contain sharp objects, the airbag 6 can be replaced with low-density materials such as foam to achieve the purpose of ensuring that the floating member 4 is subjected to sufficient buoyancy in the water.

[0049] In this embodiment, refer to Figure 4 As shown, an outer cover 501 with a water inlet hole is arranged at the water inlet end of the water inlet bottom valve 5 , and a filter screen 6 is arranged on the outer surface of the outer cover 501 .

[0050] A rotating rod 7 is provided on one side of the outer cover 501 close to the filter screen 6 , and a stirring blade 8 is connected to the rotating rod 7 .

[0051] When the water flows through the stirring piece 8 and enters the water inlet bottom valve 5, the rapid water flow impacts the stirring piece 8 to drive it to rotate. The stirring piece 8 rotates to stir the water flow at the water inlet bottom valve 5, thereby driving the water flow around it, which has a certain cleaning effect on impurities attached to the filter screen 6.

[0052] In this embodiment, a drainage pipe 101 is connected to the top of the submersible pump body 1 , and a label plate is connected to the middle surface of the submersible pump body 1 .

[0053] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
