Description

Technical Field

[0001] The present invention belongs to the technical field of submersible pumps, and in particular relates to a submersible pump for controlling groundwater level and a method thereof. Background Art

[0002] Groundwater refers to various forms of gravity-bound water buried below the Earth's surface. This refers to water found in rock and soil pores, fissures, and karst caves, freely moving under the influence of gravity. Groundwater is a vital component of water resources. Compared to surface water, groundwater offers advantages such as wide spatial distribution, strong regulatory capacity, clean water quality, and high availability. However, under certain conditions, changes in groundwater can also lead to adverse natural phenomena such as swamping, salinization, landslides, and ground subsidence. Therefore, submersible pumps can be used to extract excess groundwater, ensuring safety.

[0003] However, in actual use, it is found that since groundwater is located in the external environment, the water contains a large number of small particles. Therefore, during the operation of the submersible pump, small particles of gravel can be adsorbed onto the filter plate of the submersible pump to complete the filtration operation. However, the submersible pump is always in an adsorption state, so the small particles of gravel at this time are tightly attached to the filter net, which may cause the filter net to be blocked over time. In addition, the submersible pump equipment is immersed in water for a long time and may be attached by aquatic organisms such as algae in the water, causing the filter net to be blocked, which ultimately affects the flow of the submersible pump and the regulation effect.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0047] Example 1:

[0048] like Figures 1 to 14 As shown, a submersible pump for controlling groundwater level includes a submersible pump body 101 and an inner wall cleaning unit 200 and an outer wall cleaning unit 300 installed on the submersible pump body 101.

[0049] A filter sleeve 102 is rotatably mounted at the water inlet of the submersible pump body 101. A slide plate 103 is mounted on the top of the filter sleeve 102, and the slide plate 103 is attached to the inner wall of the water inlet of the submersible pump body 101. A shield plate 1011 is mounted on the side wall of the submersible pump body 101, and the shield plate 1011 is located below the filter sleeve 102.

[0050] The inner wall cleaning unit 200 includes a waterproof motor 201, the output shaft of the waterproof motor 201 is connected to a driving gear 2011, a driven gear ring 2012 is installed on the driving gear 2011, and the driven gear ring 2012 is connected to the filter sleeve 102, and an L-shaped plate 202 is installed on the side wall of the driven gear ring 2012. A combined track is installed on the L-shaped plate 202, and the combined track is composed of a plurality of pairs of inner grooves 2021 and outer protrusions 2022. The inner grooves 2021 and the outer protrusions 2022 are staggered, and the combined track is wavy and annular. An arched plate 203 is vertically inserted at the water inlet of the submersible pump body 101, and bristles 2031 are installed on the side wall of the arched plate 203. The bottom of the arched plate 203 is connected to the combined track. Contact, and the inner groove 2021 and the outer protrusion 2022 in the combined track are used to control the arch plate 203 to move on the inner wall of the filter sleeve 102; after the filter sleeve 102 is blocked, the waterproof motor 201 drives the driving gear 2011 and the driven gear ring 2012 to rotate, thereby driving the entire filter sleeve 102 to move, and during the movement, the internal arch plate 203 always moves downward, and the bottom of the arch plate 203 is connected to the combined track of the L-shaped plate 202. The position of the combined track changes, thereby driving the arch plate 203 to move up and down, so that the bristles 2031 rub up and down on the filter sleeve 102, cleaning the filter holes 1021 of the filter sleeve 102, and pushing the sand and gravel blocking the mesh to the outside of the submersible pump body 101.

[0051] The outer wall cleaning unit 300 includes a guide cover 301, and a scraper 302 is rotatably provided on the side wall of the guide cover 301 close to the filter sleeve 102. A transmission shaft 303 is installed at the rotation center of the scraper 302, and a rocker arm 304 is installed on the transmission shaft 303. The rocker arm 304 moves through the notch 1014 opened on the side wall of the submersible pump body 101, and the end of the rocker arm 304 is inserted into the positioning groove 3041 opened on the surface of the slide 103. The positioning groove 3041 is an arc groove with the transmission shaft 303 as the rotation center. The extension line of the inner wall of one side of the positioning groove 3041 intersects with the rotation center of the slide 103, and the side wall is in contact with the rocker arm 304. During the rotation of the filter sleeve 102, the positioning groove 3041 on the side wall pushes the rocker arm 304 to rotate, and the rocker arm 304 drives the transmission shaft to rotate, so that the scraper 302 on the surface fits with the outer wall of the filter sleeve 102, ensuring that the algae attached to the outer wall are cleaned during the rotation of the filter sleeve 102. After rotating half a circle, the rocker arm 304 automatically resets, driving the scraper 302 to seal the guide cover 301 where the algae are placed, ensuring that the algae will not be re-adsorbed onto the filter sleeve 102 during the subsequent pumping process.

[0052] like Figures 1 to 14As shown, in a specific embodiment, a cover plate 1012 is mounted on the submersible pump body 101. The cover plate 1012 is positioned above the shield plate 1011. The cover plate 1012 and the shield plate 1011 are positioned on either side of the filter sleeve 102. The diameter of the cover plate 1012 is smaller than that of the shield plate 1011. Several pairs of barrier strips 1013 are obliquely mounted on the cover plate 1012 and the shield plate 1011, with gaps between the pairs of barrier strips 1013. The shield plate 1011 ensures that the water below the submersible pump body 101 is stable, facilitating the subsequent discharge of impurities. The barrier strips 1013 support collapsed gravel in the well, ensuring the safety of the equipment.

[0053] like Figures 1 to 14 As shown, a mounting lug 105 is welded to the water outlet of the submersible pump body 101. Several pairs of positioning holes 1051 are evenly distributed on the sidewalls of the mounting lug 105. The positioning holes 1051 are through-holes. A fixing seat 1041 is welded to the top cover of the submersible pump body 101. A lifting ring 104 is rotatably connected to the fixing seat 1041. The lifting ring 104 has an anti-slip groove. The lifting ring 104 facilitates the subsequent lifting of the entire body and facilitates the movement of the submersible pump body 101.

[0054] Example 2:

[0055] The difference between the above embodiment and this embodiment is that: Figures 1 to 14 As shown, the filter sleeve 102 is evenly provided with filter holes 1021 on its surface, a guide slot 1031 is provided on the inner wall of the bottom of the filter sleeve 102, and a guide rail 1032 is installed on the inner wall of the water inlet of the submersible pump body 101. The guide slot 1031 and the guide rail 1032 cooperate with each other, and the guide rail 1032 is slidably arranged inside the guide slot 1031. The guide slot 1031 in the filter sleeve 102 rotates along the guide rail 1032, thereby limiting the movement of the filter sleeve 102.

[0056] like Figures 1 to 14 As shown, in a specific embodiment, the housing of the waterproof motor 201 is welded to the shield 1011. A reinforcing block 1015 is welded to the bottom of the shield 1011. The reinforcing block 1015 is triangular and welded to the side wall of the submersible pump body 101. The output end of the waterproof motor 201 is movable through the inner wall of the submersible pump body 101. The number of teeth on the driving gear 2011 is smaller than the number of teeth on the driven ring gear 2012. A connecting plate 2013 is mounted on the outer wall of the driven ring gear 2012, and the connecting plate 2013 is interconnected with the filter sleeve 102. When the waterproof motor 201 is started, it can drive the driving gear 2011 at the end of the output shaft to rotate. The driven ring gear 2012 is meshed with the driven ring gear 2012, and the driven ring gear 2012 can drive the connecting plate 2013 to rotate, and the connecting plate 2013 drives the filter sleeve 102 to rotate.

[0057] like Figures 1 to 14 As shown, further, a connecting seat 2032 is installed at the bottom of the arched plate 203, and a guide wheel 2033 is installed on the connecting seat 2032. The guide wheel 2033 is slidably set in the combined track. The bristles 2031 are made of soft material. The shortest distance from the arched plate 203 to the inner wall of the filter sleeve 102 is less than the length of the bristles 2031. During the rotation of the filter sleeve 102, the L-shaped plate 202 at the bottom of the filter sleeve 102 rotates synchronously, and during the rotation, the combined track in the L-shaped plate 202 moves, and the inner groove 2021 and the outer protrusion 2022 in the combined track continuously contact the guide wheel 2033 at the bottom. The guide wheel 2033 plays a guiding role. The heights of the inner groove 2021 and the outer protrusion 2022 are different, so it can drive the guide wheel 2033 installed. The arch plate 203 moves vertically up and down, and the bristles 2031 in the arch plate 203 are constantly in contact with the inner wall of the filter sleeve 102. The bristles 2031 are soft, so the bristles 2031 can be better inserted into the filter hole 1021, and can clean blocked impurities. The filter sleeve 102 rotates, and the arch plate 203 moves vertically, so the bristles 2031 in the arch plate 203 can clean different positions of the inner wall of the filter sleeve 102.

[0058] Example 3:

[0059] The difference between the above embodiment and this embodiment is that: Figures 1 to 14 As shown, a push rod 2041 is mounted on the arch plate 203, and a positioning sleeve 204 is sleeved on the push rod 2041. The positioning sleeve 204 is welded to the submersible pump body 101. A baffle 2042 is slidably provided inside the positioning sleeve 204. One side of the baffle 2042 is connected to the push rod 2041. A return spring 2043 is clamped between the inner wall of the baffle 2042 and the inner wall of the positioning sleeve 204. The compression direction of the return spring 2043 is aligned with the movement path of the push rod 2041. During the vertical movement of the arch plate 203, the push rod 2041 in the arch plate 203 is inserted into the positioning sleeve 204. The baffle 2042 in the positioning sleeve 204 is acted upon by the push rod 2041. After the baffle 2042 moves, it can drive the return spring 2043 to compress or extend. The elasticity of the return spring 2043 facilitates the arch plate 203 to always have a downward force in the later stage.

[0060] like Figures 1 to 14As shown, in a specific embodiment, the guide cover 301 is installed obliquely on the baffle 1011, and a side plate 3012 is installed on one side of the guide cover 301. The side plate 3012 is in contact with the side wall of the filter sleeve 102. A discharge groove 3011 is provided on the inner wall of the guide cover 301, and the end of the scraper 302 is chamfered 3021. A positioning shaft 3023 is installed on the scraper 302, and the positioning shaft 3023 is rotatably installed on the positioning seat 3022 of the side wall of the guide cover 301, and the positioning shaft 3023 is connected to the transmission shaft 303. When the transmission shaft 303 rotates, the transmission shaft 303 drives the positioning shaft 3023 to rotate. The rotation of the positioning shaft 3023 can rotate the scraper 302 to a certain angle, so that the scraper 302 can contact the side wall of the filter sleeve 102. The filter sleeve 102 is rotating, and the algae remaining on the surface can be cleaned by the scraper 302. During the cleaning process, a part of the algae residue falls into the side plate 3012 at the bottom, which serves the purpose of preliminary collection.

[0061] like Figures 1 to 14 As shown, further, a protective cover 3033 is installed on the side wall of the submersible pump body 101. The protective cover 3033 covers the outside of the notch 1014, and the bottom of the protective cover 3033 is movably penetrated by the transmission shaft 303. A bearing seat 3031 is sleeved on the transmission shaft 303. The bearing seat 3031 is welded to the inner wall of the protective cover 3033. A torsion spring 3032 is sleeved on the transmission shaft 303. One end of the torsion spring 3032 is clamped on the bearing seat 3031, and the other end of the torsion spring 3032 is clamped on the side wall of the rocker 304. Assuming that the slide 103 rotates counterclockwise at this time, as shown in FIG. Figure 9 Therefore, when the skateboard 103 rotates, the positioning groove 3041 in the skateboard 103 can drive the rocker arm 304 to rotate. During the rotation of the rocker arm 304, the rocker arm 304 can drive the transmission shaft 303 at the end to rotate. At this time, the transmission shaft 303 rotates around the bearing seat 3031. At this time, the torsion spring 3032 has a torsional force, which facilitates the reset of the transmission shaft 303.

[0062] A method for regulating a submersible pump for controlling groundwater level, comprising the following steps:

[0063] Step 1: Place the submersible pump body 101 into the underground well as a whole, and control the water level by controlling the power of the submersible pump body 101;

[0064] Step 2: During use, always observe the water output of the submersible pump body 101 to determine whether the filter screen of the submersible pump body 101 is unblocked;

[0065] Step 3: After blockage occurs, the waterproof motor 201 drives the driving gear 2011 and the driven ring gear 2012 to rotate, thereby driving the entire filter sleeve 102 to move, and during the movement, the internal arched plate 203 always moves downward, and the bottom of the arched plate 203 is connected to the combined track of the L-shaped plate 202. The position of the combined track changes, thereby driving the arched plate 203 to move up and down, causing the bristles 2031 to rub up and down on the filter sleeve 102, cleaning the filter holes 1021 of the filter sleeve 102, and pushing the sand and gravel blocking the mesh to the outside of the submersible pump body 101;

[0066] Step 4: During the rotation of the filter sleeve 102, the positioning groove 3041 on the side wall pushes the rocker arm 304 to rotate, and the rocker arm 304 drives the transmission shaft to rotate, so that the scraper 302 on the surface fits with the outer wall of the filter sleeve 102, ensuring that the algae attached to the outer wall are cleaned during the rotation of the filter sleeve 102, and after rotating half a circle, the rocker arm 304 automatically resets, driving the scraper 302 to seal the guide cover 301 where the algae are placed, ensuring that the algae will not be re-adsorbed onto the filter sleeve 102 during the subsequent pumping process.

[0067] The implementation principle of a submersible pump for controlling groundwater level and a method thereof in this embodiment is as follows:

[0068] First, the operator needs to put the entire device into the groundwater well, and the size of the shield 1011 is adapted to the inner diameter of the groundwater well, such as Figure 14 shown.

[0069] When groundwater needs to be pumped out, the operator needs to start the submersible pump body 101, where the submersible pump body 101 can discharge groundwater from the water inlet to the water outlet, and a filter sleeve 102 is installed at the water inlet of the submersible pump body 101. The debris in the water is filtered through the filter holes in the filter sleeve 102, reducing the impact of the debris on the impeller.

[0070] After a long time, debris may clog the outer wall of the filter sleeve 102. Then the operator needs to start the waterproof motor 201. When the waterproof motor 201 is started, it can drive the driving gear 2011 at the end of the output shaft to rotate, and the driving gear 2011 is meshed with a driven ring gear 2012, and the driven ring gear 2012 can drive the connecting plate 2013 to rotate, and the connecting plate 2013 drives the filter sleeve 102 to rotate, and the guide groove 1031 in the filter sleeve 102 rotates along the guide rail 1032.

[0071] In the rotating process of the filter sleeve 102, the L-shaped plate 202 at the bottom of the filter sleeve 102 rotates synchronously, and in the rotating process, the combined track in the L-shaped plate 202 moves, and the inner groove 2021 and the outer protrusion 2022 in the combined track are in contact with the guide wheel 2033 at the bottom at all times, and the guide wheel 2033 plays a guiding role, wherein the heights of the inner groove 2021 and the outer protrusion 2022 are different, so as to drive the arched plate 203 provided with the guide wheel 2033 to move vertically up and down, the bristles 2031 in the arched plate 203 are in contact with the inner wall of the filter sleeve 102 at all times, and the bristles 2031 are soft, so that the bristles 2031 can be better inserted into the filter holes 1021, and the blocked impurities can be cleaned, and the filter sleeve 102 is in rotary motion, and the arched plate 203 is vertically moved, so that the bristles 2031 in the arched plate 203 can clean different positions of the inner wall of the filter sleeve 102.

[0072] In the vertical moving process of the arched plate 203, the top rod 2041 in the arched plate 203 is inserted into the positioning sleeve 204, the baffle 2042 in the positioning sleeve 204 is acted on by the top rod 2041, and after the baffle 2042 moves, the return spring 2043 can be compressed or elongated, and the elasticity of the return spring 2043 facilitates that the arched plate 203 always has a downward force in the later stage.

[0073] When the filter sleeve 102 rotates, the filter sleeve 102 can drive the sliding plate 103 to rotate, assuming that the sliding plate 103 rotates counterclockwise at this time, as shown in FIG. 17. Figure 9 Therefore, in the rotating process of the sliding plate 103, the positioning groove 3041 in the sliding plate 103 can drive the swing rod 304 to rotate, and in the rotating process of the swing rod 304, the swing rod 304 can drive the transmission shaft 303 at the tail end to rotate, and the transmission shaft 303 rotates around the bearing seat 3031 at this time, and the torsional spring 3032 has a torsional force at this time, facilitating the return of the transmission shaft 303, when the transmission shaft 303 rotates, the transmission shaft 303 drives the positioning shaft 3023 to rotate, and the positioning shaft 3023 rotates to rotate the scraper 302 by a certain angle, so that the scraper 302 can be in contact with the side wall of the filter sleeve 102, and the filter sleeve 102 is rotating, and thus the surface residual algae can be cleaned by the scraper 302, and in the cleaning process, part of the algae residues fall into the side plate 3012 at the bottom, achieving the purpose of preliminary collection.

[0074] When the filter sleeve 102 rotates 180 degrees, the rocker arm 304 can be reset under the condition of the torsion spring 3032, thereby driving the scraper 302 to reset. The scraper 302 can move along the side plate 3012, thereby pushing the algae remaining on the surface into the internal guide cover 301, and the scraper 302 is sealed to the guide cover 301, resulting in the relative stability of the liquid in the guide cover 301. Through the sedimentation operation, the internal impurities fall under the baffle 1011, and the baffle 1011 makes the submersible pump body 101 absorb the water above at this time, and will not interfere with the impurities discharged at the bottom, thereby reducing the possibility of blockage here.
