Description

Technical Field

[0001] This utility model belongs to the field of submersible sewage pump technology, and specifically relates to a combined small submersible sewage pump. Background Technology

[0002] Submersible sewage pumps are mainly used in liquids containing hard solids, fibrous materials, and particularly dirty, viscous, and slippery liquids. As a result, submersible sewage pumps have received increasing attention and their application range has expanded. From simply transporting clean water, they are now used for wastewater discharge from enterprises and institutions, sewage treatment plant discharge systems, sewage drainage stations in residential areas, subways, basements, civil defense system drainage stations, municipal engineering, and the discharge of thin mud in construction projects.

[0003] Chinese patent with announcement number "CN212563681U" discloses a suspended submersible sewage pump, which relates to the field of sewage pump technology. Specifically, it is a suspended submersible sewage pump, including a sewage pump body. An air inflator is fixedly installed on the upper end of the sewage pump body, and a suspension air ring is fixedly installed on the outer side of the sewage pump body. An air guide pipe is fixedly connected between the air inflator and the suspension air ring. When the air inflator works to inflate the suspension air ring, the buoyancy of the suspension air ring increases.

[0004] However, this sewage pump has some shortcomings. After long-term use, a lot of sediment will inevitably accumulate on the inner wall of its drain pipe, which requires cleaning. Because it is not easy to disassemble it individually, users have to clean the drain pipe directly on the whole sewage pump, which is inconvenient and reduces the cleaning efficiency of the drain pipe. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a combined small submersible sewage pump to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A combined small submersible sewage pump includes a base, a bottom shell fixedly connected to the top of the base, a reinforcing ring fixedly connected to the outer side of the bottom shell, the bottom end of the reinforcing ring fixedly connected to the top of the base, a first connecting plate fixedly connected to the top of the bottom shell, a second connecting plate threadedly connected to the top of the first connecting plate, a top shell fixedly connected to the top of the second connecting plate, a handle fixedly connected to the top of the top shell, a first protective plate fixedly connected to one side of the bottom shell, a second protective plate snapped onto one side of the first protective plate, a drain pipe installed on one side of the second protective plate, the drain pipe communicating with the inner side of the bottom shell, a first slot provided on one side of the second protective plate, the first slots all penetrating the second protective plate and one side of the first protective plate, a second slot provided on the inner wall of the first slot, a circular groove provided on the inner side of the first slot, a first locking block snapped onto the inner side of the first slot, a second locking block fixedly connected to the outer side of the first locking block, the second locking block snapping onto the inner side of the circular groove.

[0008] As a preferred technical solution, a retaining spring that matches the second retaining block is installed on the inner side of the circular groove, and the other side of the second retaining block is engaged with one side of the retaining spring. The second retaining block is engaged with the inner side of the circular groove by the retaining spring.

[0009] As a preferred technical solution, a limiting block is fixedly connected to the other side of the second protective plate, and a limiting groove matching the limiting block is opened on one side of the first protective plate, with the limiting block inserted into the inner side of the limiting groove.

[0010] As a preferred technical solution, a second sealing ring is fixedly connected to the other side of the second protective plate, and a second sealing groove matching the second sealing ring is opened on one side of the first protective plate, with the second sealing ring covering the inner side of the second sealing groove.

[0011] As a preferred technical solution, the top end of the first connecting plate is provided with a threaded groove, and the bottom end of the second connecting plate is fixedly connected with a connecting ring. The outer wall of the connecting ring is provided with an external thread that matches the threaded groove. The connecting ring is threaded to the inner side of the threaded groove through the external thread. The second connecting plate is threaded to the top end of the first connecting plate through the threaded groove, the connecting ring and the external thread.

[0012] As a preferred technical solution, a first sealing ring is fixedly connected to the top of the first connecting plate, and a first sealing groove matching the first sealing ring is fixedly connected to the bottom of the second connecting plate, with the first sealing ring covering the inner side of the first sealing groove.

[0013] As a preferred technical solution, a groove is provided at the bottom of the base, and a rubber pad is fixedly connected to the inside of the groove. The rubber pad covers the inside of the groove, and the position of the bottom of the rubber pad is on the same horizontal line as the position of the bottom of the base.

[0014] In summary, the present invention has the following main advantages:

[0015] First, the presence of the first locking block facilitates the insertion of the second locking block into the circular groove. By adjusting the second locking block to a position that is not directly opposite to the second groove, the first locking block can be effectively engaged and limited, thereby fixing the position of the second connecting plate. When the drain pipe needs to be cleaned later, the first locking block can be rotated to adjust the second locking block to a position symmetrical to the second groove, allowing the first locking block to be pulled out directly. This also makes it easier for the user to pull the second connecting plate out of the first connecting plate, so as to bring the drain pipe out. This allows the user to easily disassemble the drain pipe individually for cleaning.

[0016] Secondly, due to the presence of the limiting block, the insertion of the limiting block can effectively limit the second connecting plate, thereby effectively improving the stability and accuracy of the second connecting plate's point engagement. Its second sealing ring can effectively seal the contact points of the first and second connecting plates, thereby improving the overall sealing performance of the connection between the two to avoid water leakage. Due to the presence of the connecting ring, it is convenient to connect the top shell, so as to connect the bottom shell and the top shell into a whole protective shell, which can effectively improve the safety protection of the outer wall of the sewage pump. When it needs to be disassembled later, the connecting ring can be unscrewed directly, which also facilitates the user to inspect or maintain the sewage pump later. Attached Figure Description

[0024] Example

[0025] refer to Figures 1 to 6 This embodiment of a combined small submersible sewage pump includes a base 1, a bottom shell 2 fixedly connected to the top of the base 1, a reinforcing ring 3 fixedly connected to the outer side of the bottom shell 2, the bottom end of the reinforcing ring 3 fixedly connected to the top of the base 1, a first connecting plate 4 fixedly connected to the top of the bottom shell 2, a second connecting plate 8 threadedly connected to the top of the first connecting plate 4, a top shell 7 fixedly connected to the top of the second connecting plate 8, a handle 12 fixedly connected to the top of the top shell 7, a first protective plate 13 fixedly connected to one side of the bottom shell 2, a second protective plate 14 snapped onto one side of the first protective plate 13, a drain pipe 15 installed on one side of the second protective plate 14, the drain pipe 15 communicating with the inner side of the bottom shell 2, a first slot 16 opened on one side of the second protective plate 14, the first slot 16 penetrating one side of both the second protective plate 14 and the first protective plate 13, a second slot 17 opened on the inner wall of the first slot 16, and a second slot 17 opened on the inner side of the first slot 16. There is a circular groove 18. The inner side of the first slot 16 is engaged with a first locking block 24. The outer side of the first locking block 24 is fixedly connected with a second locking block 25 that matches the second slot 17. The second locking block 25 is engaged with the inner side of the circular groove 18. In use, due to the presence of the first locking block 24, it is easy for the second locking block 25 to be engaged into the circular groove 18. The second locking block 25 is adjusted to a position that is not directly corresponding to the second slot 17, thereby effectively engaging and limiting the first locking block 24 to achieve the effect of fixing the position of the second connecting plate 8. When it is necessary to clean the drain pipe 15 later, the first locking block 24 is rotated to adjust the second locking block 25 to a position that is symmetrical with the second slot 17, so that the first locking block 24 can be directly pulled out. This also makes it easier for the user to directly pull out the second connecting plate 8 from the first connecting plate 4 so as to bring out the drain pipe 15. This achieves the purpose of facilitating the user to disassemble the drain pipe 15 individually for cleaning.

[0026] refer to Figures 1 to 4A retaining spring 19 matching the second retaining block 25 is installed on the inner side of the circular groove 18. The other side of the second retaining block 25 is engaged with one side of the retaining spring 19. The second retaining block 25 is engaged with the inner side of the circular groove 18 through the retaining spring 19. Due to the presence of the retaining spring 19, the second retaining block 25 can be engaged twice, which can effectively improve the stability of the second retaining block 25 and also improve the stability of the second protective plate 14 engagement.

[0027] refer to Figures 1 to 4 On the other side of the second protective plate 14, a limiting block 22 is fixedly connected. On one side of the first protective plate 13, a limiting groove 21 matching the limiting block 22 is provided. The limiting block 22 is inserted into the inner side of the limiting groove 21. Due to the presence of the limiting block 22, the insertion of the limiting block 22 can effectively limit the second connecting plate 8, thereby effectively improving the stability and accuracy of the point-to-point engagement of the second connecting plate 8.

[0028] refer to Figures 1 to 4 A second sealing ring 23 is fixedly connected to the other side of the second protective plate 14. A second sealing groove 20 matching the second sealing ring 23 is opened on one side of the first protective plate 13. The second sealing ring 23 covers the inner side of the second sealing groove 20. Due to the presence of the second sealing ring 23, the second sealing ring 23 can effectively seal the contact point of the first connecting plate 4 and the second connecting plate 8, thereby improving the overall sealing performance of the connection between the two and avoiding water leakage.

[0029] refer to Figure 5 and Figure 6 The top of the first connecting plate 4 is provided with a threaded groove 5, and the bottom of the second connecting plate 8 is fixedly connected with a connecting ring 9. The outer wall of the connecting ring 9 is provided with an external thread 10 that matches the threaded groove 5. The connecting ring 9 is threaded to the inner side of the threaded groove 5 through the external thread 10. The second connecting plate 8 is threaded to the top of the first connecting plate 4 through the threaded groove 5, the connecting ring 9 and the external thread 10. Due to the presence of the connecting ring 9, it is convenient to connect the top shell 7, so that the bottom shell 2 and the top shell 7 can be connected into an integral protective shell, which can effectively improve the safety protection of the outer wall of the sewage pump. When it needs to be disassembled later, the connecting ring 9 can be unscrewed directly. It is also convenient for users to inspect or maintain the sewage pump later.

[0030] refer to Figure 5 and Figure 6 The top end of the first connecting plate 4 is fixedly connected to a first sealing ring 6, and the bottom end of the second connecting plate 8 is fixedly connected to a first sealing groove 11 that matches the first sealing ring 6. The first sealing ring 6 covers the inner side of the first sealing groove 11. Due to the presence of the first sealing ring 6, the contact point between the first connecting plate 4 and the second connecting plate 8 can be effectively sealed, thereby effectively improving the overall connection sealing performance of the bottom shell 2 and the top shell 7, so as to achieve a good sealing and protection effect.

[0031] refer to Figure 2 The bottom end of the base 1 is provided with a groove 26, and a rubber pad 27 is fixedly connected to the inner side of the groove 26. The rubber pad 27 covers the inner side of the groove 26. The bottom end of the rubber pad 27 is on the same horizontal line as the bottom end of the base 1. Due to the presence of the rubber pad 27, which is made of rubber, it has good anti-slip ability and rubber shock absorption ability, thereby effectively improving the stability of the base 1 when it is placed.

[0032] Operating principle and advantages: During use, the presence of the first locking block 24 facilitates the insertion of the second locking block 25 into the circular groove 18. Adjusting the second locking block 25 to a position that is not directly aligned with the second groove 17 effectively engages and limits the first locking block 24, thus fixing the second connecting plate 8. When cleaning the drain pipe 15 later, rotating the first locking block 24 adjusts the second locking block 25 to a symmetrical position with the second groove 17, allowing the first locking block 24 to be directly removed. This also facilitates the user's direct removal of the second connecting plate 8 from the first connecting plate 4, bringing the drain pipe 15 out with it. This allows for convenient disassembly and cleaning of the drain pipe 15 individually. The presence of the retaining spring 19 provides secondary engagement of the second locking block 25, effectively improving the stability of the second locking block 25 and the stability of the second protective plate 14 engagement. The presence of the limiting block 22 effectively limits the second connecting plate 8. The presence of the second sealing ring 23 effectively improves the stability and accuracy of the second connecting plate 8's snap-fit ​​connection. The second sealing ring 23 effectively seals the contact points of the first connecting plate 4 and the second connecting plate 8, thereby improving the overall sealing performance of the connection and preventing leakage. The presence of the connecting ring 9 facilitates the docking of the top shell 7, connecting the bottom shell 2 and the top shell 7 into a single protective shell, effectively improving the safety protection of the sewage pump's outer wall. When disassembly is required later, the connecting ring 9 can be unscrewed directly, facilitating future inspection and maintenance of the sewage pump. The presence of the first sealing ring 6 effectively seals the contact points of the first connecting plate 4 and the second connecting plate 8, further improving the overall sealing performance of the bottom shell 2 and the top shell 7, providing excellent sealing protection. The presence of the rubber pad 27, made of rubber, provides excellent anti-slip and shock absorption capabilities, effectively improving the stability of the base 1's placement.
