Description

Technical Field

[0001] The utility model relates to the technical field of submersible sewage pumps, in particular to a novel self-cleaning submersible sewage pump. Background Art

[0002] Submersible sewage pumps are widely used in urban drainage systems, industrial wastewater treatment, rural domestic sewage treatment and other fields. Their working principle is mainly to drive the impeller to rotate through the motor to extract sewage from the sewage pool and transport it to the designated location;

[0003] Submersible sewage pumps are usually installed at the bottom of sewage pools. Since sewage pools contain various solid particles, fibrous materials and other debris, these debris can easily enter the pump body during operation, blocking the flow channel and affecting the normal operation of the pump. This will not only reduce the drainage efficiency of the pump, but may also cause pump failure, requiring shutdown for cleaning or maintenance, thereby increasing the cost of use and the difficulty of maintenance. Utility Model Content

[0004] In view of this, and in view of the deficiencies of the prior art, the utility model provides a novel self-cleaning submersible sewage pump to solve the problem in the prior art that the submersible sewage pump is installed at the bottom of the sewage pool, which makes it easy for debris to enter the pump body and cause it to be blocked.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new self-cleaning submersible sewage pump, comprising a pump body, a water inlet chamber is arranged at the bottom of the pump body, a drainage pipe is arranged on one side of the outer surface of the water inlet chamber, a mounting plate is arranged at the bottom of the water inlet chamber, connecting seats are evenly arranged at the bottom of the mounting plate, connecting shafts are arranged between the opposite surfaces of the connecting seats, support cylinder 1 is arranged on the outer surface of the connecting shaft, support cylinder 2 is arranged on the inner surface of the support cylinder 1, and support columns are arranged on the inner surface of the support cylinder 2; a cleaning component is arranged at the bottom of the mounting plate, which is used to prevent debris in the sewage from entering the interior of the pump body.

[0006] Preferably, the mounting plate is triangular in shape and has three connecting seats, which are used to ensure the stability of the pump body. The bottom of the support columns are provided with protrusions, which are used to enable the support columns to stably support the pump body in the sludge.

[0007] Preferably, a torsion spring is arranged between the opposite surfaces of the connecting seat and the supporting tube, the torsion spring is sleeved on the outer surface of the connecting shaft, the outer surface of the supporting tube close to the connecting seat is provided with a convex plate 2, and the inside of the connecting seat is provided with a convex plate 1, and the convex plate 1 is adapted to the convex plate 2.

[0008] Preferably, the outer surfaces of the support tube 2 and the support column are provided with sliding grooves, the inside of the sliding grooves are provided with slide plates, telescopic springs are provided between the bottom of the slide plates and the opposite surface of the sliding grooves, and limiting blocks are provided on the top of the slide plates. The inner surfaces of the support tube 1 and the support tube 2 are provided with limiting grooves, and the limiting grooves are adapted to the limiting blocks.

[0009] Preferably, magnet one is evenly arranged on the bottom of the mounting plate, and magnet two is arranged on the outer wall of the support tube one close to the mounting plate, and the magnetic poles of magnet two and magnet one are opposite.

[0010] Preferably, the cleaning assembly includes a transmission rod, which is arranged at the bottom end of the output shaft of the impeller in the pump body, a cleaning rod is arranged at the bottom end of the transmission rod, a filter screen is arranged at the bottom of the mounting plate, and the cleaning rod is located on the outer surface of the filter screen.

[0011] Preferably, the filter screen is a cylindrical structure, which is used to increase the sewage flow rate, the cleaning rod has a T-shaped cross-section, and the protruding end of the cleaning rod is in contact with the outer surface of the filter screen, which is used to improve the effect of cleaning debris.

[0012] Compared with the prior art, the utility model provides a new self-cleaning submersible sewage pump, which has the following beneficial effects:

[0013] Through the multi-level support effect of support cylinder 1, support cylinder 2 and support column, the bottom of the pump body can be pushed away from the bottom of the sewage pool, and the torsion spring can make the support part fully expand to improve the stability of the pump body. At the same time, the convex plate 2 on the support cylinder 1 and the convex plate 1 on the connecting seat can limit the expansion angle of the support part, thereby avoiding the problem that the bottom of the pump body touches the bottom and the debris in the sewage enters the pump body and blocks the flow channel. This not only ensures the drainage efficiency of the pump body and enables it to operate normally, but also effectively reduces the probability of pump failure, thereby reducing the cost of use.

[0014] The filter net set up can block the debris in the sewage to prevent the debris from entering the pump body and affecting the normal operation of the pump body. The transmission rod drives the cleaning rod to rotate around the outer surface of the filter net and scrape off the debris adsorbed on it, avoiding the problem of debris clogging the filter net and causing the working efficiency of the submersible sewage pump to be reduced, thereby achieving the self-cleaning effect of the submersible sewage pump, which can not only significantly improve the working efficiency of the submersible sewage pump, but also extend the service life of the submersible sewage pump.

[0015] By pressing the limit block, the limit block is caused to slide along the inside of the slide groove and the telescopic spring is contracted, thereby releasing the limiting effect of the support column and the support tube 2, so that the two can be retracted into the inside of the support tube 1, and then by arranging mutual attraction between magnet 1 and magnet 2, the supporting part of the pump body can be quickly expanded and retracted, so that the submersible sewage pump does not take up space, which not only facilitates storage and transportation, but also enhances adaptability and stability.

[0026] The utility model is further described in detail below based on the drawings and embodiments.

[0027] Example

[0029] Among them, the mounting plate 4 is triangular in shape, and the number of connecting seats 5 is three, which is used to ensure the stability of the pump body 1. The bottom of the support column 8 is provided with a protrusion 19, which is used to enable the support column 8 to firmly support the pump body 1 in the sludge; and a torsion spring 18 is provided between the connecting seat 5 and the opposite surface of the support tube 6. The torsion spring 18 is sleeved on the outer surface of the connecting shaft 17, which is used to enable the support tube 6 to be in an expanded state. The outer surface of the support tube 6 close to the connecting seat 5 is provided with a convex plate 2 13, and the inside of the connecting seat 5 is provided with a convex plate 12. The convex plate 12 is adapted to the convex plate 2 13. Through the mutual cooperation between the two, the rotation angle of the support tube 6 can be limited to avoid the opening angle being too large and unable to stabilize the pump body 1.

[0030] Further examples:

[0031] Please refer to Figure 3 , Figure 4 , Figure 6 as well as Figure 7As shown, the outer surfaces of the support tube 2 7 and the support column 8 are provided with a slide groove 20, and a slide plate 10 is arranged inside the slide groove 20. A telescopic spring 9 is arranged between the bottom of the slide plate 10 and the opposite surface of the slide groove 20, and a limit block 11 is arranged on the top of the slide plate 10. The inner surfaces of the support tube 1 6 and the support tube 2 7 are provided with a limit groove 16, and the limit groove 16 is adapted to the limit block 11, wherein the telescopic spring 9 can squeeze the limit block 11 to make it fit tightly in the slide groove 20, thereby limiting the moving distance of the support tube 2 7 and the support column 8, and the support tube The lengths of support tube 1 6, support tube 2 7 and support column 8 decrease successively, thereby ensuring that support column 8, support tube 2 7 and support tube 1 6 are successively retracted into the interior thereof, so as to facilitate their retraction and collection together; at the same time, magnets 14 are evenly arranged at the bottom of mounting plate 4, and magnets 2 15 are arranged on the outer wall of one side of support tube 1 6 close to mounting plate 4, and magnets 2 15 have opposite magnetic poles to magnet 1 14, thereby enabling support tube 1 6 to be adsorbed on the bottom of mounting plate 4, thereby reducing the overall volume of pump body 1 and improving its flexibility and portability.

[0032] Further Embodiments

[0033] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 6 As shown, the cleaning assembly includes a transmission rod 22, which is arranged at the bottom end of the output shaft of the impeller in the pump body 1, and can rely on the output end of the pump body 1 to drive the transmission rod 22 to work; a cleaning rod 23 is arranged at the bottom end of the transmission rod 22, and a filter screen 21 is arranged at the bottom of the mounting plate 4, and the cleaning rod 23 is located on the outer surface of the filter screen 21; the filter screen 21 is a cylindrical structure, which is used to increase the sewage flow rate, the cross-section of the cleaning rod 23 is T-shaped, and the protruding end of the cleaning rod 23 is in contact with the outer surface of the filter screen 21, which is used to improve the effect of cleaning debris.

[0034] Everything in the above example works like this:

[0035] When in use, the user first moves the support tube 16 to separate the magnet 14 from the magnet 2 15. At this time, the torsion spring 18 loses its limiting effect and continues to stretch, so that the support tube 16 rotates along the connecting shaft 17 until the convex plate 2 13 on the support tube 16 contacts the convex plate 12 on the connecting seat 5, so that the three support tubes 6 can be fully unfolded. Then, during the rotation of the support tube 16, the support tube 2 7 inside it slides along its interior until the limit block 11 on the support tube 27 slides to the through hole opened in the limit groove 16. At this time, the telescopic spring 9 loses its restriction and continues to stretch, and continuously pushes the slide plate 10 to slide along the inside of the slide groove 20, causing the limit block 11 to extend into the through hole on the limit groove 16, thereby completing the limiting effect on the support tube 27. Similarly, the support column 8 extends to the outside of the support tube 27 and limits it according to the same steps as above, thereby completing the limiting effect on the support tube 27. The stable support of the pump body 1 prevents the bottom of the pump body 1 from touching the bottom and causing debris in the sewage to enter the pump body 1 and block the flow channel. This not only ensures the drainage efficiency of the pump body 1 and enables it to operate normally, but also effectively reduces the probability of failure of the pump body 1, thereby reducing the cost of use; when the pump body 1 is working, the filter screen 21 at the bottom of the water inlet chamber 3 can block the debris in the sewage and prevent the debris from entering the pump body 1 and affecting the normal operation of the pump body 1. At the same time, the output end of the pump body 1 drives the transmission rod 22 to rotate, and then the transmission rod 22 drives the cleaning rod 23 to rotate and continuously scrapes off the debris adsorbed on the outer surface of the filter screen 21, which can prevent the debris from clogging the filter screen 21 and causing the working efficiency of the submersible sewage pump to be reduced, thereby achieving the effect of self-cleaning of the submersible sewage pump, which can not only significantly improve the working efficiency of the submersible sewage pump, but also extend the service life of the submersible sewage pump;

[0036] When the pump body 1 is used up or needs to be stored and placed, the user first presses the limit block 11 on the outer surface of the support tube 27 to make it slide inward. At this time, the slide plate 10 slides inward along the inside of the slide groove 20 and continuously squeezes the telescopic spring 9 to shrink, causing the limit block 11 to gradually slide into the slide groove 20, thereby releasing the limiting effect of the support column 8, so that it can slide along the inside of the support tube 27 and be retracted into it. Similarly, press the limit block 11 on the outer surface of the support tube 6, and follow the same steps as above to make the support tube 27 slide into the inside of the support tube 6 together with the support column 8. Subsequently, the support tube 6 is rotated in the opposite direction to make the convex plate 12 move away from the convex plate 213. At this time, the torsion spring 18 on the connecting shaft 17 continuously shrinks, and the magnet 2 15 on the support tube 6 and the magnet 14 on the mounting plate 4 attract each other, thereby quickly unfolding and retracting the supporting part of the pump body 1, so that the submersible sewage pump does not take up space, can be conveniently stored and transported, and at the same time enhances adaptability and stability.
