Description

Technical Field

[0001] The utility model relates to the field of multistage pumps, in particular to an immersed multistage pump. Background Art

[0002] Immersed multistage pump is a special type of multistage pump, the pump body of which is completely immersed in the liquid. It is usually used to pump deep well water, groundwater or other liquid media.

[0003] An immersion pipe is provided at the water suction pipe structure of the immersed multi-stage pump. This structure can extend the water inlet pipe for immersing the water inlet of the pump body. In order to ensure that the pump body can stably extract the liquid medium, a filtering structure is provided at the water inlet end of the immersion pipe for protection. Most of these filtering structures are fixedly connected to the water suction pipe through a screw and nut structure. Since the filtering structure serves as a guarantee for fluid extraction and entry of the entire pump body, it needs to be kept unobstructed before use. Therefore, it is often necessary to disassemble and clean the filtering structure. The threaded connection for fixing makes the disassembly and installation operations time-consuming and labor-intensive when multiple groups of connecting mechanisms are connected together.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] It should be noted that the immersion tube 4 usually has a longer pipe section, which can effectively draw water from deeper water bodies, and the immersion tube 4 can help guide the fluid to flow to the pump inlet, reduce flow resistance, and improve the efficiency of the pump. At the same time, the immersion tube 4 can adjust the immersion depth according to changes in the water level to ensure that the multi-stage pump body 1 can work normally at different water levels.

[0036] Specifically, a connection plate 201 is provided at one end of the water pump 2 away from the multi-stage pump body 1 , the bottom of the connection plate 201 is used for sleeve connection with the immersion tube 4 , and the side of the connection plate 201 is used for connection with the connection mechanism.

[0037] The protection mechanism is arranged at the end of the immersion pipe 4 away from the water extraction pipe 2, and is used for filtering protection when the immersion pipe 4 is pumping water;

[0038] Specifically, the protection mechanism includes a protection cover 6, which is sleeved on the bottom of the connecting sleeve 5. The sides and bottom of the protection cover 6 are provided with inlets, and filter plates 601 are provided in the multiple inlets.

[0039] It should be noted that the setting of the filter plate 601 can filter and block water during pumping. The setting of the filter plate 601 prevents impurities such as branches or plastic bags from entering the pump body, ensuring that the multi-stage pump body 1 can stably pump water.

[0040] The connecting mechanism has one end sleeved on the outer wall of the protective mechanism, and the other end of the connecting mechanism is connected to the water pumping pipe 2. The connecting mechanism is used for installing the protective mechanism on the water pumping pipe 2.

[0041] Specifically, the connection mechanism includes:

[0042] The connecting sleeve 5 is sleeved on the end of the immersion pipe 4 away from the water pumping pipe 2, and the bottom of the connecting sleeve 5 is used to sleeve the protective mechanism;

[0043] Connecting rods 7, multiple connecting rods 7 are respectively arranged around the sides of the multiple connecting sleeves 5;

[0044] Furthermore, a plurality of connection blocks 501 are arranged around the side of the connection sleeve 5 , and the bottoms of the plurality of connection rods 7 are respectively arranged on the top ends of the plurality of connection blocks 501 .

[0045] It should be noted that the connection block 501 is provided to support the connection rod 7. After such operation and setting, the connection rod 7 can maintain connection with the connection sleeve 5, thereby completing the traction locking of the protective mechanism by cooperating with the connection disk 201.

[0046] Locking parts: multiple groups of locking parts are respectively arranged on the top of the connecting rod 7, and the locking parts are used to cooperate with the connecting disk 201 to lock the protective mechanism.

[0047] Furthermore, a receiving groove 701 is provided at the top of the connecting rod 7, and the receiving groove 701 is used to set the locking part.

[0052] It should be noted that under the setting of the torsion spring 11, the second clamp 9 and the first clamp 8 both rotate in the direction away from each other in the initial state. At the same time, since the second clamp 9 and the first clamp 8 are sleeved on the outer wall of the same supporting rotating rod 10, the two rotate in an articulated manner, that is, the tops of the second clamp 9 and the first clamp 8 rotate away from each other. In the setting of this scheme, the tops of the second clamp 9 and the first clamp 8 both have a hook-shaped structure. Through this structure, the tops of the second clamp 9 and the first clamp 8 pass through the connecting through hole to the top of the connecting disk 201. The hook-shaped structure hooks at the top of the connecting disk 201 at the connecting through hole, thereby realizing a locking and blocking type. At the same time, this connection method makes it possible to release the lock by only pinching the second clamp 9 and the first clamp 8 so that the two rotate toward each other, thereby completing the release of the lock, which saves time and effort in operation.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
