Description

Technical Field

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

[0002] A submersible pump is an important device for pumping water from deep wells. When in use, the whole unit works underwater, extracting groundwater to the ground surface, and is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship ballasting, and can also be used for fountain landscapes.

[0003] However, there are still some deficiencies in the current submersible pumps during use. In the process of using traditional submersible pumps, the water inlet is prone to blockage, resulting in the impeller idling, often causing the submersible pump to malfunction. And when the water inlet is blocked, manual handling is required, which is time-consuming and laborious and reduces work efficiency. At the same time, for some river channels with relatively serious bottom silt, when using a submersible pump, traditional submersible pumps cannot increase the distance between the water inlet and the river bottom according to different usage conditions, which easily leads to the situation where the silt blocks the water inlet.

[0004] An anti-blocking submersible pump disclosed in the existing patent (publication number: CN220302352U) belongs to the field of water pumps. It solves the problem that the water inlet of the existing submersible pump is easily blocked by silt or other impurities. This anti-blocking submersible pump includes a pump body with a water inlet port and a water outlet port, an impeller, and a drive motor for controlling the rotation of the impeller to work. The impeller is located inside the pump body and is connected to the output shaft of its drive motor. A anti-blocking device for preventing impurities from blocking is fixedly installed at the water inlet port of the pump body. The output shaft of the drive motor passes through the pump body and is connected to its impeller. A main dredging cone for preventing impurities and silt from blocking is also provided on the output shaft of the drive motor. The anti-blocking device includes a connecting cylinder fixedly connected to the water inlet port of the pump body and several dredging components arranged on the side wall of the connecting cylinder and used for preventing blockage. The several dredging components are arranged at intervals in the circumferential direction along the side wall of the connecting cylinder. By setting the anti-blocking device and the main dredging cone, this structure can effectively prevent the problem that the water inlet port of the submersible pump is blocked by silt and other impurities and cannot work normally, thereby reducing the failure rate of the submersible pump, enabling it to work in various environments, greatly extending its service life and improving work efficiency.

[0005] However, the above technical solution still has certain defects. In the above technical solution, the impurities are cut by the spiral blade groove during use. However, many waterweeds in the water are relatively slender and very tough. After these waterweeds come into contact with the main dredging cone and the auxiliary dredging cone, due to the conical shape of the main dredging cone and the auxiliary dredging cone, the waterweeds are very easy to wind around the outer walls of the main dredging cone and the auxiliary dredging cone, and the spiral blade groove cannot exert enough cutting force on the waterweeds, resulting in the water pump being blocked by waterweeds. Therefore, an anti-blocking submersible pump is proposed. Summary of the Utility Model

[0006] Based on this, the purpose of the present utility model is to provide a clog - proof submersible pump to solve the technical problems raised in the above - mentioned background.

[0007] To achieve the above - mentioned purpose, the present utility model provides the following technical solution: A clog - proof submersible pump includes a submersible pump main body. The submersible pump main body includes a motor. The bottom end of the motor is fixedly connected with a pressure chamber. The output end of the motor extends into the interior of the pressure chamber. The output end of the motor is fixedly connected with a connection disk. The connection disk is located on the inner wall of the pressure chamber. The bottom end of the connection disk is fixedly connected with a first impeller located inside the pressure chamber. The bottom end of the first impeller is fixedly connected with a cutting piece located outside the pressure chamber. The bottom end of the pressure chamber is fixedly connected with a base, and the base is sleeved outside the cutting piece.

[0008] As a preferred technical solution of the clog - proof submersible pump of the present utility model, a second impeller is fixedly connected between the first impeller and the cutting piece, and the second impeller is coaxially connected with the first impeller.

[0009] As a preferred technical solution of the clog - proof submersible pump of the present utility model, the top end of the motor is fixedly connected with a handle, and two groups of hanging rings are fixedly connected to the top end of the handle.

[0010] As a preferred technical solution of the clog - proof submersible pump of the present utility model, a connection mechanism is communicated with the side wall of the pressure chamber. The connection mechanism includes a water outlet pipe, and the end of the water outlet pipe is in an umbrella shape.

[0014] In summary, the present utility model mainly has the following beneficial effects:

[0015] 1. In the process of the water pump running, the cutting piece rotates at high speed.

Moreover, the waterweeds can be chopped to avoid entanglement inside the submersible pump. Through the rotation of the first impeller and the second impeller, the suction force of the submersible pump on the water flow is increased, improving the working efficiency of the submersible pump.

[0016] 2. In this utility model, the water hose is sleeved on the end of the water outlet pipe. By rotating the threaded sleeve, the water hose can be tightly attached to the outer wall of the water outlet pipe. Reversely rotating the threaded sleeve can release the fixation of the water hose on the outer wall of the water outlet pipe, making it more convenient to connect and disassemble the water hose to the submersible pump. This enables faster placement of the submersible pump and quicker disassembly of the water hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0026] Next, the embodiments of the present utility model will be described according to its overall structure.

[0027] An anti-blocking submersible pump, as Figures 1 to 5 shown, includes a submersible pump body 1. The submersible pump body 1 includes a motor 101. The bottom end of the motor 101 is fixedly connected to a pressure chamber 102. The output end of the motor 101 extends into the interior of the pressure chamber 102. The output end of the motor 101 is fixedly connected to a connection disk 103. The connection disk 103 is located on the inner wall of the pressure chamber 102. The bottom end of the connection disk 103 is fixedly connected to a first impeller 104 located inside the pressure chamber 102. The bottom end of the first impeller 104 is fixedly connected to a cutting blade 106 located outside the pressure chamber 102. The bottom end of the pressure chamber 102 is fixedly connected to a base 107. The base 107 is sleeved outside the cutting blade 106. A second impeller 105 is fixedly connected between the first impeller 104 and the cutting blade 106. The second impeller 105 is coaxially connected to the first impeller 104. The top end of the motor 101 is fixedly connected to a handle, and two groups of lifting rings are fixedly connected to the top end of the handle.

[0028] The motor 101 drives the connection disk 103 to rotate, so that the connection disk 103 drives the first impeller 104 to rotate. The first impeller 104 pushes water flow into the pressure chamber 102 and discharges it from the water outlet pipe 201. During the rotation of the first impeller 104, the cutting blade 106 is driven to rotate, so that impurities in the water are cut by the cutting blade 106 during the process of passing through the base 107, thereby preventing waterweeds from winding around the first impeller 104 and avoiding the submersible pump being blocked by waterweeds. During the rotation of the first impeller 104, the second impeller 105 rotates synchronously, thereby pushing water flow into the interior of the pressure chamber 102, thus improving the pumping efficiency of the submersible pump.

[0029] Please refer particularly to Figure 1 , Figure 2 , Figure 3 and Figure 5 , a connection mechanism 2 is communicated with the side wall of the pressure chamber 102. The connection mechanism 2 includes a water outlet pipe 201. The end of the water outlet pipe 201 is in an umbrella shape. A sleeve 202 is fixedly sleeved on the outer wall of the water outlet pipe 201. A threaded sleeve 203 is threadedly connected to the outer wall of the sleeve 202. The threaded sleeve 203 extends into the inner wall of the sleeve 202. A tapered sleeve 204 is fixedly sleeved on the inner wall of the threaded sleeve 203. A sealing ring 206 is fixedly sleeved on the inner wall of the tapered sleeve 204. A rubber ring 205 is fixedly sleeved on the inner wall of the tapered sleeve 204. Multiple convex strips are arranged on the outer wall of the rubber ring 205. The rubber ring 205 is located below the sealing ring 206.

[0030] After the water hose is put on the outside of the water outlet pipe 201, the tapered sleeve 204 is driven downward by rotating the threaded sleeve 203, so that the tapered sleeve 204 drives the rubber ring 205 to move downward, so that the rubber approaches the umbrella-shaped outer wall at the end of the water outlet pipe 201, so that the tapered sleeve 204 pushes the rubber ring 205 to fit the outer wall of the water hose. When the water hose is removed, the threaded sleeve 203 is rotated in the opposite direction so that the tapered sleeve 204 drives the rubber ring 205 away from the water outlet pipe 201, so that the water hose is no longer tightly wrapped around the outer wall of the water outlet pipe 201, so that the water hose can be separated from the water outlet pipe 201, and in the process of pumping water, when the waterway is filled with water, the water props up the water hose, so that the outer wall of the water hose fits against the sealing ring 206, thereby further improving the sealing between the water hose and the water outlet pipe 201.

[0031] When in use, the cutting blade 106 rotates rapidly during the operation of the water pump, so that when water plants, branches or even smaller fish are sucked into the water pump, these debris are chopped up by the cutting blade 106, so that these debris will not block the submersible pump, and the water plants can be chopped up to prevent them from being entangled in the inside of the submersible pump. The rotation of the first impeller 104 and the second impeller 105 improves the suction force of the submersible pump on the water flow, so that the working efficiency of the submersible pump is improved. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.

[0032] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
