Description

Technical Field

[0001] The utility model relates to the technical field of submersible sewage pumps, in particular to an anti-clogging submersible sewage pump. Background Art

[0002] Submersible sewage pumps, also known as submersible sewage pumps, are capable of efficiently pumping large-diameter liquids and are commonly used to pump impure wastewater, such as domestic sewage, wastewater, and rainwater. However, long-fiber plastics, cotton thread, and cloth strips found in sewage can easily become entangled in the impeller shaft during operation, affecting the pump's efficiency and service life.

[0003] In the prior art, although it has been proposed to crush long-fiber analogues by setting a cutting device to reduce the possibility of submersible sewage pumps being blocked, there are still certain defects in use. For example, in a submersible sewage pump with patent number CN220522809U, the output shaft of the driving motor is extended into the base to drive a number of cutting knives to rotate for cutting. However, in this patented technical solution, since the direction of rotation of the cutting knives is parallel to the direction of impurity entry, when long-fiber analogues enter the base, tough long-fiber analogues (such as hair, strip-shaped plastics, etc.) that cannot be effectively broken by a single cut will still be entangled on the rotating shaft as the cutting knives rotate. Therefore, there is an urgent need for an anti-clogging submersible sewage pump to solve the above-mentioned problems. Utility Model Content

[0032] 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.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] Reference Figures 1-4 The utility model provides an anti-clogging submersible sewage pump, comprising:

[0035] The bottom end of the submersible sewage pump body is fixedly connected to a base 1, and a water inlet is opened on the side wall of the base 1.

[0036] The wire winding plate 3 is arranged in the base 1. A driving motor 2 is provided in the submersible sewage pump body. The output shaft of the driving motor 2 extends into the base 1 and is connected to the wire winding plate 3. The wire winding plate 3 rotates in a direction parallel to the water inlet.

[0037] The cutting knife 4 is arranged in the base 1. The cutting knife 4 is configured to slide in contact with one side of the wire winding plate 3 and reciprocate relative to the wire winding plate 3. The cutting knife 4 moves in a direction perpendicular to the water inlet.

[0038] The utility model extends the output shaft of the driving motor 2 directly into the base 1, uses the driving motor 2 to provide power to drive the wire winding plate 3 to rotate in a direction parallel to the water inlet, thereby winding the long fiber analogues onto the wire winding plate 3, and then sets a cutting knife 4 corresponding to the wire winding plate 3. The cutting knife 4 can slide in contact with the wire winding plate 3 and reciprocate relative to the wire winding plate 3 to achieve cutting of the long fiber analogues, and the cutting knife 4 moves in a direction perpendicular to the water inlet, thereby improving the cutting effect of the long fiber analogues, and effectively alleviating the situation where the submersible sewage pump is blocked due to the entanglement of long fiber analogues and affecting the working efficiency.

[0039] In one embodiment of the present invention, referring to Figure 4 The cutting knife 4 can adopt a structure with a right triangle cross section, so that the cutting knife 4 has cutting edges in both horizontal and vertical directions. While cutting back and forth in the vertical direction, it can also rotate synchronously with the wire winding plate 3 to perform horizontal cutting, meeting the needs of conventional rotation cutting and enhancing the cutting effect.

[0040] Furthermore, it also includes:

[0041] The collar 5 is fixedly connected to the cutting knife 4 , and a transmission assembly is provided in the base 1 . The collar 5 is connected to the driving motor 2 through the transmission assembly. When the wire winding plate 3 rotates, the collar 5 reciprocates relative to the wire winding plate 3 .

[0042] The drive motor 2 is connected to the ring 5 through the transmission component, so that the ring 5 can move back and forth relative to the winding plate 3, thereby driving the cutting knife 4 to repeatedly cut the wound long fiber analogue, and reasonably utilizing the drive motor 2 to provide power.

[0043] Furthermore, the transmission assembly includes:

[0044] The shell 6 is fixed to the center of the top surface of the base 1. A rotating rod 7 is connected inside the shell 6. The ring 5 is key-driven on the rotating rod 7. The ring 5 is slidably connected to the shell 6 and has a vertical upward elastic tendency.

[0045] A pair of hemispheres 8 are fixed to the top surface of the collar 5 and the inner wall of the top end of the shell 6 respectively. The hemispheres 8 are arranged opposite to each other. When the rotating rod 7 rotates, the protruding ends of the hemispheres 8 intermittently contact each other.

[0046] By utilizing the key transmission between the collar 5 and the rotating rod 7, the collar 5 is driven to rotate during the rotation of the rotating rod 7. During the process, the hemispheres 8 distributed on the collar 5 and the shell 6 are in intermittent contact, so that when a pair of hemispheres 8 are in contact with each other, the collar 5 slides away from the shell 6. When the pair of hemispheres 8 are not in contact, the collar 5 is reset and moved vertically upward, thereby realizing the reciprocating motion of the cutting knife 4 driven by the collar 5, thereby improving the cutting effect of long fiber analogs.

[0047] It can be understood that multiple pairs of hemispheres 8 can be selectively provided and fixed to the inner wall of the top end of the shell 6 and the top surface of the collar 5 along the circumferential direction.

[0048] Furthermore, the transmission assembly also includes:

[0049] The baffle 9 is fixedly connected to the rotating rod 7 and is used to seal the bottom end of the housing 6. The outer peripheral side of the baffle 9 is connected to the housing 6 via a sliding bearing 10.

[0050] The spring 11 is wound on the rotating rod 7, and the two ends of the spring 11 are respectively against the bottom surface of the collar 5 and the top surface of the baffle 9.

[0051] The baffle 9 is fixedly connected to the rotating rod 7, and the baffle 9 is transferred to the housing 6 through the sliding bearing 10, so that the baffle 9 can seal the housing 6 to reduce the entry of pollutants into the housing 6, and the spring 11 is respectively used to resist the ring 5 and the baffle 9 to provide the ring 5 with a vertical upward elastic tendency.

[0052] Furthermore, it also includes:

[0053] The connecting rod 12 is fixedly connected to the bottom surface of the collar 5 in the vertical direction. The bottom end of the connecting rod 12 passes through the baffle 9 and is fixedly connected to the cutting knife 4. The connecting rod 12 and the baffle 9 are limited and slidably connected.

[0054] The connecting rod 12 is in limited sliding connection with the baffle 9 , and the connecting rod 12 is fixedly connected with the collar 5 in the vertical direction, so that the key transmission between the collar 5 and the rotating rod 7 is realized.

[0055] Furthermore, the top end of the rotating rod 7 is coaxially fixed to the output shaft of the driving motor 2, the bottom end of the rotating rod 7 extends out of the shell 6 and is connected to the base 1, and the wire winding plate 3 is fixed to the side wall of the part of the rotating rod 7 extending out of the shell 6.

[0056] Furthermore, a plurality of wire wrapping plates 3 are provided along the circumference of the rotating rod 7 , and the number of the cutting knives 4 is the same as that of the wire wrapping plates 3 and they correspond one to one.

[0057] Reference Figure 2 The wire winding plate 3 and the cutting knife 4 are arranged in a one-to-one correspondence, and several cutting knives 4 and the wire winding plate 3 are equally spaced along the axial direction and arranged on the part of the rotating rod 7 extending out of the shell 6. The water inlet is opened on the side wall of the base 1. When the wire winding plate 3 rotates, the long fiber analogue can be wound and rolled along the direction parallel to the water inlet.

[0058] Furthermore, the wire winding plate 3 is provided with a plurality of wire winding holes in sequence along the axial direction, and the radius of the hemisphere 8 is not less than the vertical length of the wire winding hole.

[0059] By setting the radius of the hemisphere 8 to be greater than the vertical length of the wire winding hole, when a pair of hemispheres 8 are in sliding contact, the hemispheres 8 push against each other to drive the ring 5 to move the cutting knife 4, so that the moving distance of the cutting knife 4 is greater than the vertical length of the wire winding hole. The cutting knife 4 is in contact with the edge of the wire winding hole to improve the cutting effect of the long fiber analogue.

[0060] Furthermore, a top plate 13 is fixed to the top surface of the base 1 , and the housing 6 is fixed to the center of the bottom surface of the top plate 13 . The top plate 13 is provided with a plurality of grid holes that pass through both ends.

[0061] Furthermore, the base 1 is fixed with an impeller housing 14 and a motor housing 15 in sequence in a vertically upward direction, the drive motor 2 is fixed in the motor housing 15, the output shaft of the drive motor 2 extends into the impeller housing 14 and is fixed to the axis of the impeller 16, and a water outlet is provided on the side wall of the impeller housing 14.

[0062] The working principle of this practical information anti-clogging submersible sewage pump is:

[0063] During use, tough, long-fiber analogs, some of which are difficult to cut with conventional rotational methods, are introduced into the base 1 along the water inlet. The drive motor 2 drives the rotating rod 7 to rotate the winding plate 3, wrapping and collecting the long-fiber analogs. As the winding plate 3 rotates and reels, the baffle 9 and connecting rod 12 drive the collar 5 and the rotating rod 7, causing the rotating rod 7 to rotate the collar 5. The hemispheres 8 on the collar 5 slide into contact with the hemispheres 8 on the housing 6. The hemispheres 8, acting against each other, drive the collar 5 downward in a vertical direction, compressing the spring 11 during this movement. As the collar 5 moves, the long-fiber analogs on the winding plate 3 are vertically cut, enhancing the cutting effect. After the hemispheres 8 disengage, the spring 11 resets the collar 4. As the rotating rod 7 rotates, the hemispheres 8 make contact again, achieving reciprocating motion for the collar 4.
