Description

Technical Field

[0001] The utility model relates to the technical field of submersible pumps, in particular to a submersible pump for wells with adaptive water depth. Background Art

[0002] Submersible pumps are important equipment for pumping water from deep wells. When in use, the entire unit submerges in the water to extract groundwater to the surface. This water is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscapes. This is especially true in farmland irrigation, where surface water irrigation is inconvenient for some farmlands. Submersible pumps are used for pumping water for irrigation after digging a well. However, in actual use, impurities in the water body easily float on the water surface, causing blockages when pumping water near the water surface. Silt is also prone to sedimentation at the bottom of the well, and blockages are also prone to occur when the pumping position is close to the bottom. Generally, the position of the submersible pump is fixed by a rope and needs to be adjusted according to the water level. As a result, the water level in the well cannot be adjusted in time after changes, causing the pump to easily become blocked when pumping water near the water surface and near the bottom of the water, which brings inconvenience to use.

[0004] In view of the deficiencies in the prior art, the utility model provides a submersible pump for a well with adaptive water depth, which solves the inconvenience of having to manually adjust the fixed position of the pump according to the water depth in the well.

[0005] (2) Technical solution

[0007] Preferably, a thread is provided on the lower side of the outer wall of the mounting ring seat, and the mounting ring seat is mounted with a filter cartridge cover through the outer wall thread.

[0008] Preferably, an inner filter ring is installed on the inner wall of the mounting ring seat and at a position close to the bottom, and the cavity between the mounting ring seat and the inner filter ring forms a filter tank.

[0009] Preferably, the inner side of the inner filter ring is raised upward.

[0012] Compared with the prior art, the present invention provides a submersible pump for wells with adaptive water depth, which has the following beneficial effects:

[0013] 1. The adaptive water depth submersible pump for wells adjusts the distance between the top of the support screw and the mounting ring seat by rotating the support screw, thereby adjusting the distance between the water suction port at the bottom of the submersible pump and the water surface. After the submersible pump is placed into the well, the buoyancy plate floats on the water surface, thereby adjusting the distance between the water inlet at the bottom of the submersible pump and the water surface. It is easy to use and does not require manual lifting and depth control using ropes on the ground.

[0014] 2. This self-adaptive water depth submersible pump for wells will move up and down with the water surface when the water depth inside the well changes, so that the water inlet at the bottom of the submersible pump always maintains the same distance from the water surface, preventing the support screw from approaching the water surface and sucking in floating impurities on the water surface. There is no need to manually adjust the pump position, making it easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 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.

[0020] See also Figure 1-3 The utility model provides a submersible pump for a well with adaptive water depth, including a mounting ring seat 1 and a submersible pump 6. A locking column 2 is installed on the outer wall of the mounting ring seat 1. A thread is provided at the position where the locking column 2 and the mounting ring seat 1 contact each other. A rotating handle 3 for rotation is installed at the outer end of the locking column 2. The inner end of the locking column 2 penetrates the mounting ring seat 1 and extends into the inner side of the mounting ring seat 1. The inner end of the locking column 2 is rotatably installed with a connecting ring seat 4 through a bearing. A fixed The splint 5 and the submersible pump 6 are clamped on the inner side of the fixed splint 5. A water outlet pipe 61 for drainage is provided on the top of the submersible pump 6. A fixing nut 7 is installed on the bottom of the mounting ring seat 1. A support screw 8 is installed on the inside of the fixing nut 7 through a thread. A protective ball cap 9 is installed on the bottom end of the support screw 8. The top end of the support screw 8 passes through the mounting ring seat 1 and extends to the top of the mounting ring seat 1. A buoyancy plate 10 is installed on the top of the support screw 8 through a thread. A pipe through-hole 11 is opened at the center of the buoyancy plate 10.

[0021] Furthermore, a thread is provided on the lower side of the outer wall of the mounting ring seat 1, and a filter cartridge cover 14 is installed on the mounting ring seat 1 through the outer wall thread. The filter cartridge cover 14 filters impurities in the water body sucked in from the outside and the bottom to prevent the submersible pump 6 from being blocked.

[0022] Furthermore, an inner filter ring 12 is installed on the inner wall of the mounting ring seat 1 and at a position near the bottom. The cavity between the mounting ring seat 1 and the inner filter ring 12 forms a filter tank 13. The water flowing from the upper side to the lower side is filtered by the inner filter ring 12, and the filtered impurities are gathered in the filter tank 13, reducing the impurities entering the filter tube cover 14.

[0023] Furthermore, the inner side of the inner filter ring 12 is convex upward, which prevents impurities from rolling inward above the inner filter ring 12 and entering the interior of the filter cartridge cover 14 .

[0024] Furthermore, the fixing splint 5 is made of elastic metal, and the arc-shaped inner wall of the fixing splint 5 is provided with anti-slip grooves. The locking column 2 presses the fixing splint 5 to contact the submersible pump 6 through the connecting ring seat 4, thereby pressing and fixing the submersible pump 6. When pressed, the fixing splint 5 is deformed and elastically pressed and fixed, thereby effectively preventing loosening, and the anti-slip grooves can prevent the submersible pump 6 from sliding in the up and down directions, further improving the stability of the fixation.

[0025] Furthermore, the buoyancy plate 10 is made of plastic, and a cavity is opened on the inner wall of the buoyancy plate 10 for increasing buoyancy. The surface of the buoyancy plate 10 is coated with a protective paint. The buoyancy of the device is provided by the buoyancy plate 10, and the anti-corrosion ability is further improved by the protective paint, thereby increasing the service life.

[0026] When in use, place the submersible pump 6 on the inner side of the three fixing splints 5, and then rotate the handle 3 to drive the locking column 2 to rotate. The locking column 2 rotates and moves inward under the action of the thread. The locking column 2 drives the fixing splint 5 to approach the submersible pump 6 and support it through the connecting ring seat 4. By adjusting the three locking columns 2, the three fixing splints 5 are moved from the outside to the inside to squeeze and fix the submersible pump 6, thereby completing the installation of the submersible pump 6. Then, according to the water depth in the well and the cleanliness of the water surface, observe the depth of the bottom of the submersible pump 6 under the water surface in the well, rotate the support screw 8 to pass through the fixing nut 7, and adjust the support screw 8 and the distance between the top of the mounting ring seat 1. After the distance adjustment is completed, the remaining two support screws 8 are also installed, and then the buoyancy plate 10 is placed above the three support screws 8. The support screws 8 are rotated and threadedly connected to the buoyancy plate 10 respectively. The drainage pipe is passed through the pipe through-hole 11 and installed on the top of the outlet pipe 61. After the assembly is completed, the device is placed into the well through a rope, and the submersible pump 6 is submerged under the water surface. The buoyancy provided by the buoyancy plate 10 keeps the distance between the bottom water inlet of the submersible pump 6 and the water surface unchanged. The submersible pump 6 will not be blocked by impurities floating on the water surface when pumping water, nor will it sink to the bottom of the well to inhale silt and cause blockage.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
