Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, and in particular to a high-pressure submersible pump. Background Technology

[0002] A high-pressure submersible pump is a mechanical device specifically designed for underwater operation, such as pumping water, draining water, or raising water levels. A high-pressure submersible pump generally consists of a waterproof motor, a pump body, and an impeller housed within the pump body. During operation, the waterproof motor drives the impeller within the pump body, thereby creating negative pressure within the pump body to draw water in and discharge it.

[0003] Since high-pressure submersible pumps typically operate underwater, they are prone to sucking in aquatic plants, sand, and other debris of varying sizes. This debris entering the pump body can damage the impeller, leading to pump failure. Current high-pressure submersible pumps generally lack a filtration system, resulting in the inability to filter debris and frequent malfunctions. Some pumps incorporate a filter at the inlet to filter aquatic plants and some sand, but this method suffers from poor filtration and is difficult to clean. Therefore, a submersible pump with superior filtration capabilities and easy post-operation debris removal is needed.

[0004] A cutting-type submersible sewage pump is disclosed in utility model application number CN202420789871.5 and publication number CN222025972U. It includes a pump body, a water delivery component fixedly connected to the upper part of the pump body, a first connecting block fixedly connected to the right end of the water delivery component, a threaded groove on the right side of the first connecting block, a threaded sleeve threadedly connected inside the threaded groove, a second connecting block fixedly connected to the right side of the threaded sleeve, a connecting pipe fixedly connected to the right side of the second connecting block, and clamping blocks slidably connected to both the outer sides of the first and second connecting blocks. A threaded block is fixedly connected to the upper part of the clamping block, and a bidirectional threaded rod is threadedly connected inside the threaded block. However, in use, it still suffers from the problem of failing to filter impurities, easily causing the submersible pump to malfunction and stop working. Utility Model Content

Detailed Implementation

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Example:

[0033] like Figures 1 to 4 As shown, in order to solve the above problems, this embodiment discloses a high-pressure submersible pump, including a submersible pump body 10 and a filter assembly 20. The submersible pump body 10 is provided with a water inlet 100 at the bottom, and the filter assembly 20 is provided at the bottom of the submersible pump body 10 and is configured to cooperate with the water inlet 100.

[0034] The filter assembly 20 includes a mounting base 200 and a filter element 201. The mounting base 200 has a mounting cavity 202 inside, one end of which extends through the bottom of the mounting base 200. The top of the mounting base 200 is detachably connected to the bottom of the submersible pump body 10. The top of the mounting base 200 has a connecting port 203 that cooperates with the water inlet 100 and communicates with the mounting cavity 202. The filter element 201 is disposed inside the mounting cavity 202 and cooperates with the connecting port 203. The filter element 201 is detachably connected to the top of the mounting base 200. The upper end of the mounting base 200 has several water inlet windows 204 that communicate with the mounting cavity 202.

[0035] The filter element 201 includes a first filter screen 205, a second filter screen 206, and a mounting structure 207. The mounting structure 207 is detachably connected to the top of the mounting base 200 and is configured to cooperate with the communication port 203. The first filter screen 205 and the second filter screen 206 are sequentially arranged inside the mounting structure 207 and are detachably connected to the mounting structure 207. The first filter screen 205 is positioned above the second filter screen 206. The first filter screen 205 is used to filter small particles of sand and gravel, and the second filter screen 206 is used to filter large particles of sand and gravel.

[0036] In use, water flows through the inlet window 204 on the mounting base 200 into the mounting cavity 202, and then passes sequentially through the second filter screen 206 and the first filter screen 205 in the filter element 201 for filtration. The filtered water then enters the submersible pump body 10 through the connecting port 203 and the inlet 100, and is then pumped out. Compared to traditional submersible pumps, the high-pressure submersible pump of this invention can perform dual filtration during water pumping, thereby effectively reducing impurities entering the submersible pump body 10, thus effectively improving the working efficiency and service life of the submersible pump. This solves the problem that current high-pressure submersible pumps cannot filter impurities during use, which easily causes the submersible pump to malfunction and stop working. At the same time, the filter element 201 is detachably connected to the top of the mounting base 200, and the first filter screen 205 and the second filter screen 206 are detachably connected to the mounting structure 207, which makes it easy to remove the first filter screen 205 and the second filter screen 206 for cleaning, thereby facilitating the cleaning or replacement of the first filter screen 205 and the second filter screen 206.

[0037] like Figures 4 to 6As shown, to facilitate the assembly and disassembly of the first filter screen 205 and the second filter screen 206, this embodiment is modified based on the above embodiment. The difference lies in that the mounting structure 207 includes a first mounting part 208, a second mounting part 209, and a third mounting part 210 connected sequentially from top to bottom. The second mounting part 209 has a mounting ring 211 inside, which is fixedly connected to the inner wall of the second mounting part 209. The bottom of the first mounting part 208 is disposed within the second mounting part 209 and is detachably connected to the second mounting part 209. The first filter screen 205... The first filter 205 is disposed between the mounting ring 211 and the first mounting part 208, with one end of the first filter 205 contacting the top of the mounting ring 211 and the other end contacting the bottom of the first mounting part 208. The top of the third mounting part 210 is disposed inside the second mounting part 209 and is detachably connected to the second mounting part 209. The second filter 206 is disposed between the mounting ring 211 and the third mounting part 210, with one end of the second filter 206 contacting the bottom of the mounting ring 211 and the other end contacting the top of the third mounting part 210. The top of the first mounting part 208 is detachably connected to the top of the mounting base 200.

[0038] In use, the first filter screen 205 is fixed by the first mounting part 208, and the second filter screen 206 is fixed by the third mounting part 210, which facilitates the installation and removal of the first filter screen 205 and the second filter screen 206.

[0039] like Figure 5 As shown, in order to facilitate the disassembly and assembly of the filter element 201, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the top of the first mounting part 208 is provided with a plug-in part 212, the plug-in part 212 is fixedly connected to the first mounting part 208, and the plug-in part 212 can be inserted into the communication port 203 on the top of the mounting base 200 and is interference-fitted with the communication port 203.

[0040] When in use, a plug-in connection structure is adopted, which facilitates the installation and removal of filter element 201.

[0041] like Figure 4 As shown, in order to improve the sealing performance of the connection between the plug-in part 212 and the communication port 203, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that a sealing ring 213 is provided on the top of the first mounting part 208. The sealing ring 213 is embedded in the top of the first mounting part 208. When the plug-in part 212 is inserted into the communication port 203, the sealing ring 213 contacts the top of the mounting base 200 and forms a seal.

[0042] like Figure 5As shown, in order to facilitate the filtration of small particles of sand and gravel, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the first filter screen 205 includes a first filter screen 214 and a first ring body 215. The first filter screen 214 is fixedly disposed in the first ring body 215, and the first ring body 215 is disposed between the first mounting part 208 and the mounting ring 211.

[0043] As a further preferred option, the first filter screen 214 is a medium-particle filter screen in the prior art, with a pore size range of 1mm-3mm.

[0044] like Figure 6 As shown, in order to facilitate the filtration of large particles of sand and gravel, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the second filter screen 206 includes a second filter screen 216 and a second ring body 217. The second filter screen 216 is fixedly disposed in the second ring body 217, and the second ring body 217 is disposed between the third mounting part 210 and the mounting ring 211.

[0045] As a further preferred option, the second filter 216 adopts a coarse particle filter screen in the prior art, with a pore size range of 3mm-10mm.

[0046] In one embodiment, as a further preferred embodiment, the bottom of the first mounting part 208 is threadedly connected to the second mounting part 209, and the bottom of the third mounting part 210 is threadedly connected to the second mounting part 209. When the first mounting part 208 is connected to the second mounting part 209, the first ring 215 can be fixed between the first mounting part 208 and the mounting ring 211. When the third mounting part 210 is connected to the second mounting part 209, the second ring 217 can be fixed between the third mounting part 210 and the mounting ring 211.

[0047] When the first filter screen 205 needs to be removed, the first mounting part 208 can be unscrewed from the second mounting part 209 to remove the first filter screen 205. When installing the first filter screen 205, simply place the first filter screen 205 inside the second mounting part 209, so that the first ring body 215 contacts the mounting ring 211, and then screw the first mounting part 208 into the second mounting part 209, so that the first mounting part 208 presses the first ring body 215 against the top of the mounting ring 211 to complete the installation of the first filter screen 205.

[0048] When the second filter 206 needs to be removed, simply unscrew the third mounting part 210 from the second mounting part 209 to remove the second filter 206. When installing the second filter 206, simply place the second filter 206 on the third mounting part 210, then screw the third mounting part 210 into the second mounting part 209, and place the second ring 217 against the bottom of the mounting ring 211 to complete the installation of the second filter 206.

[0049] In order to facilitate the quick assembly and disassembly of the first mounting part 208 and the second mounting part 209, the outer side of the second mounting part 209 is provided with several grooves 218.

[0050] The grooves 218 can increase the friction between the second mounting part 209 and the hand. Therefore, when connecting the first mounting part 208 and the second mounting part 209, the first mounting part 208 can be screwed into the second mounting part 209 by rotating the second mounting part 209.

[0051] like Figures 6 to 7 As shown, in order to facilitate the quick assembly and disassembly of the third mounting part 210 and the second mounting part 209, the third mounting part 210 is provided with a cross mounting bracket 219, which is fixedly connected to the third mounting part 210. A turning handle 220 is fixedly provided at the bottom of the cross mounting bracket 219.

[0052] In use, the handle 220 can be manually turned, which in turn drives the cross-shaped mounting bracket 219, which in turn drives the third mounting part 210, causing the third mounting part 210 to screw into the second mounting part 209. The cross-shaped mounting bracket 219 facilitates water flow.

[0053] like Figures 5 to 7 As shown, in order to prevent the filter element 201 from falling off, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the bottom of the mounting base 200 is provided with a locking element 221. The locking element 221 includes a locking sleeve 222 and a contact ring 223. The contact ring 223 is located on the top of the locking sleeve 222. The contact ring 223 and the locking sleeve 222 are connected by a plurality of connecting rods 224. The plurality of connecting rods 224 are spaced apart. One end of the connecting rod 224 is fixedly connected to the locking sleeve 222, and the other end is fixedly connected to the contact ring 223. One end of the locking sleeve 222 can be screwed into the mounting cavity 202 and is detachably connected to the mounting base 200 by threads. When the locking sleeve 222 is screwed into the mounting cavity 202, the contact ring 223 contacts the bottom of the third mounting part 210 to limit the mounting structure 207.

[0054] When in use, screw one end of the locking sleeve 222 into the mounting cavity 202 so that the contact ring 223 contacts the bottom of the third mounting part 210, thereby further fixing the filter element 201 and preventing the filter element 201 from falling off.

[0055] In the above embodiments, the submersible pump body 10 may be a submersible pump in the prior art, or may adopt the following structure.

[0056] like Figure 2 , Figure 8 As shown, the submersible pump body 10 includes a pump body 101, an impeller 102, and a drive structure 103. The inlet 100 is located at the bottom of the pump body 101. The top of the mounting base 200 is detachably connected to the bottom of the pump body 101. The impeller 102 is rotatably installed inside the pump body 101, and the bottom of the impeller 102 is rotatably connected to the inlet 100. The drive structure 103 is located at the top of the pump body 101 and is detachably connected to the pump body 101. The drive structure 103 is configured to cooperate with the impeller 102 and is used to drive the impeller 102.

[0057] The drive structure 103 is a waterproof motor as described in the prior art.

[0058] The output shaft of the drive structure 103 passes through the top of the pump body 101 and is rotatably connected to the top of the pump body 101. One end of the output shaft of the drive structure 103 extends into the pump body 101 and is connected to the impeller 102. The impeller 102 is fixedly mounted on the output shaft of the drive structure 103.

[0059] The pump body 101 is equipped with a water outlet 104.

[0060] In use, the impeller 102 is driven to rotate at high speed by the drive structure 103, so that water can enter the pump body 101 from the inlet 100 and then be discharged through the outlet 104.

[0061] like Figure 8 As shown, in order to facilitate the use of this utility model, this embodiment is modified based on the above embodiment. The difference from the above embodiment is that the top of the drive structure 103 is provided with a lifting member, which includes a handle 105 and a lifting ring 106. The handle 105 is detachably connected to the top of the drive structure 103 by bolts, and the lifting ring 106 is set on the handle 105 and fixedly connected to the handle 105.

[0062] When in use, the high-pressure submersible pump described in this utility model can be carried to the place where it is needed by the handle 105, and then the high-pressure submersible pump can be lifted and put into the water by the lifting ring 106.

[0063] Working principle of this utility model:

[0064] In use, water flows through the inlet window 204 on the mounting base 200 into the mounting cavity 202, and then passes sequentially through the second filter screen 206 and the first filter screen 205 in the filter element 201 for filtration. The filtered water then enters the submersible pump body 10 through the connecting port 203 and the inlet 100, and is then pumped out. Compared to traditional submersible pumps, the high-pressure submersible pump of this invention can perform dual filtration during water pumping, thereby effectively reducing impurities entering the submersible pump body 10, thus effectively improving the working efficiency and service life of the submersible pump. Simultaneously, the filter element 201 is detachably connected to the top of the mounting base 200, and the first filter screen 205 and the second filter screen 206 are detachably connected to the mounting structure 207, making it easy to remove the first filter screen 205 and the second filter screen 206 for cleaning, thus facilitating the cleaning or replacement of the first filter screen 205 and the second filter screen 206.

[0065] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
