Description
Technical Field
[0001] This utility model relates to the field of submersible pumps, specifically a clog-resistant submersible electric pump for sewage and waste. Background Technology
[0002] A submersible pump is a special type of water pump designed to extract liquids from deep water to the surface or transport them to other locations. It can extract liquids from deep wells, pools, lakes, or other water sources and transport them to higher altitudes or over longer distances. Submersible pumps are characterized by their compact structure, light weight, and ease of installation, use, and relocation. They are suitable for various applications, including water supply systems, irrigation, sewage treatment, and industrial uses. Their working principle involves a motor driving an impeller to rotate, thereby generating pressure and flow to meet different needs.
[0003] Application number CN217216158U discloses a submersible pump, which includes: a motor body having a motor cavity and multiple stator leads disposed within the motor cavity; a junction box connected to the motor body, the junction box having a wiring cavity; a cable, one end of which is located within the wiring cavity and includes multiple conductors; a terminal block, the two ends of which are a first end and a second end, the first end being located within the wiring cavity and the second end being located within the motor cavity, the multiple stator leads being connected to the second end by a plug-in connection; and a plug, with multiple conductors connected to the plug, the plug being connected to the first end by a plug-in connection. This design enables quick plugging and unplugging of the submersible pump plug, simplifies the wiring method and disassembly / removal steps of the submersible pump, thereby improving the wiring efficiency of the submersible pump, avoiding the situation in the prior art where the wiring quality cannot be guaranteed due to the small space of the wiring cavity, enhancing the reliability of the cable connection, and ensuring the safety of the submersible pump operation.
[0004] In existing technologies, the function of diverting and transmitting water is achieved through components such as the motor body, junction box, and submersible pump. The junction box has a wiring cavity, which facilitates the insertion and removal of cables and terminals, enabling quick plugging and unplugging of the submersible pump plug and ensuring the submersible pump is powered on and running. However, during the operation of the submersible pump, the water flow contains a large amount of dirt and debris, which can easily enter the submersible pump and cause blockages, leading to damage to the internal parts of the submersible pump. At the same time, the submersible pump is powered on and the impeller rotates to introduce water flow, which can easily generate vibrations, making the submersible pump unstable in the water and causing the pump body to tip over, affecting the operation of the submersible pump.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-5 As shown, this utility model is a submersible electric pump for preventing clogging of sewage and waste, including a base structure 1, a filter structure 2, and a pump body structure 3. The base structure 1 includes a base plate 101, a base 102 is installed on the top of the base plate 101, and shock-absorbing springs 103 and spring sheets 104 are installed in sequence inside the base 102. The top of the base 102 is connected to the bottom of the filter chamber 201. The filter structure 2 includes a filter chamber 201, and a filter screen 202 is installed inside the filter chamber 201. A housing 303 is fitted on the top of the filter chamber 201. A housing 303 is fitted on the outside of the pump body structure 3. A rotor 301, a rotating shaft, and an impeller 302 are installed in sequence inside the housing 303.
[0027] The base structure 1 has a base plate 101 at the bottom, and bases 102 are installed on both sides of the top of the base plate 101. The inner walls of the bases 102 are provided with shock-absorbing springs 103, and the top of each shock-absorbing spring 103 is equipped with a spring piece 104. By installing several shock-absorbing springs 103 in the base structure 1, the vibration generated by the submersible pump during operation is dissipated by multiple sets of shock-absorbing springs 103, reducing the degree of shaking of the submersible pump and thus enhancing the stability of the submersible pump in water. A water storage tank 105 is installed on the top of the base 102. Water inlets are provided on both sides of the outside of the water storage tank 105. A filter plate 106 is installed inside the water storage tank 105, and one side of the filter plate 106 is connected to the outlet 107.
[0028] The filter structure 2 includes a filter chamber 201. The bottom of the filter chamber 201 is adapted to the bottom of the water storage tank 105. A filter screen 202 is installed at the bottom of the filter chamber 201. By installing the filter chamber 201 at the top of the water storage tank 105 and cooperating with the filter screen 202 at the bottom, impurities and dirt in the water are filtered and retained inside the filter plate 106 inside the water storage tank 105. This maintains the normal flow of water to the outlet 107, prevents internal blockage, and facilitates cleaning of impurities inside the filter plate 106, thereby improving the working efficiency of the submersible pump.
[0029] The lower end of the housing 303 is movably connected to the upper edge of the filter chamber 201. The rotor 301 is installed at the top inside the housing 303. The rotating shaft and impeller 302 are installed in sequence below the rotor 301. The top of the rotor 301 is connected to the motor 304. Handles 305 are provided on both sides above the housing 303.
[0030] An arc-shaped groove is provided on the inner wall of the base 102. Three sets of shock-absorbing springs 103 are located inside the base 102 and are arranged in a circular array to fit the inner wall. A spring piece 104 is installed at the center of the top of the shock-absorbing spring 103 and is adapted to connect with the groove on the inner side of the base 102.
[0031] The top of the filter screen 202 is provided with several filter holes, which are arranged in several groups and are evenly distributed and extend to the bottom of the filter screen 202. The filter holes perform secondary filtration of fine impurities in the water, preventing impurities from entering the pump body structure 3 and causing damage to the parts, thus enhancing protection.
[0032] An opening is provided on the top of the housing 303. An electric wire is installed inside the opening. One end of the electric wire is connected to the motor 304, and the other end is connected to the power plug. When the power plug is powered, it drives the rotor 301 and impeller 302 in the pump body structure 3 to rotate, generating centrifugal force that causes the liquid to be sprayed outward. The liquid in the housing 303 gradually slows down and flows out through the outlet 107, thus realizing the water delivery work.
[0033] Working principle: During use, the base structure 1 and filter structure 2 are installed correspondingly, and the power is connected through the power plug on the top of the housing 303 in the pump body structure 3. This causes the rotor 301 and impeller 302 inside to rotate in the same direction. The shock-absorbing spring 103 inside the base 102 in the base structure 1 gradually reduces the frequency of vibration generated by the pump body structure 3 during operation, thereby reducing the degree of pump body shaking and ensuring the stability of the submersible pump in water. Water flows into the interior through the inlets on both sides of the water storage tank 105 and passes through the internal filter plate 106. The filter plate 106 filters out dirt and impurities from the water and traps them around the filter. The water inside the filter plate 106 undergoes secondary filtration through the top filter chamber 201 and the bottom filter screen 202, preventing impurities from entering the pump body structure 3 and causing blockages or damage to components, thus improving safety. The impeller 302 in the pump body structure 3 rotates rapidly, generating centrifugal force that gradually slows the flow rate of the water sprayed inside. The water is then delivered to the desired location through the outlet 107, completing the water delivery process. A handle 305 is provided on the top of the casing 303 for easy carrying and handling of the submersible pump. The above-disclosed preferred embodiments of this utility model are only for illustrating the present utility model. The preferred embodiments do not describe all details exhaustively, nor do they limit the utility model to the specific implementation described. Obviously, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
