Description

Technical Field

[0001] The present invention relates to the technical field of water pumps, and specifically to a device for adaptively adjusting the operating efficiency of a water pump. Background Technique

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transmits the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid-base solutions, emulsions, suspension emulsions, and liquid metals, etc.

[0003] During the use of a water pump, according to η=(1 - h_loss / H)*100%, where H is the head and h_loss is the resistance suffered by the water flow when rising in the pipeline, the efficiency of the water pump is affected by the head. The longer the head, the lower the efficiency of the pump. Currently, when a submersible pump is in use, it is usually directly placed at the bottom of the water. The position of the water pump cannot be adjusted with the change of water depth, and it cannot ensure that the flow rate and head of the submersible pump are always controlled within the range indicated on the nameplate during operation. It cannot ensure that the submersible pump operates at the highest efficiency point, and its effectiveness cannot be fully utilized, resulting in a waste of resources. Summary of the Invention

[0017] By setting the turbine and the worm, the motor can be vertically fixedly installed on the L-shaped mounting frame, reducing the width of the L-shaped mounting frame.

[0018] Further, a plurality of positioning holes are opened on the surface of the sliding rod.

[0019] By setting a plurality of positioning holes, the submersible pump can be used at different depths of water correspondingly.

[0020] Further, the bottom of the top positioning plate is fixedly connected with a telescopic support arm through a rotating member. A universal wheel is fixedly installed at the bottom end of the telescopic support arm.

[0021] By setting universal wheels at the bottom of the telescopic support arm, it is convenient to move it.

[0022] Further, the rotating member includes a support shaft. Both ends of the support shaft are fixed to the bottom of the top positioning plate through fixed blocks. An external threaded tube is sleeved on the surface of the support shaft. An internal threaded tube is threadedly connected to the surface of the external threaded tube.

[0023] Through the cooperation between the internal threaded tube and the external threaded tube, the internal threaded tube can be rotated by the rotating handle so that the first notch and the second notch correspond to each other and are conveniently sleeved on the surface of the support shaft to form a rotational fit, and then rotated again to stagger them, which is simple to install and disassemble.

[0024] (III) Beneficial effects

[0025] The present invention has the following beneficial effects:

[0026] (1) The device for adaptively adjusting the operating efficiency of a water pump is configured by arranging a driving member on an L-shaped mounting frame to cooperate with a trigger adjustment component. When the submersible pump is working, its water inlet can be set at a position just below the liquid surface by - centimeters. When the water inlet is about two centimeters below the liquid surface, the motor can be started by triggering the adjustment component to drive the driving member to move the submersible pump downward or upward, so that it always remains just below the liquid surface. The submersible pump does not need to be placed on the bottom of the water, which greatly reduces the head of the submersible pump and improves the use efficiency of the water pump.

[0027] (2) The device for adaptively adjusting the operating efficiency of the water pump can support the submersible pump, motor, etc. by setting a positioning sleeve and cooperating with a delay adjustment member. After the motor stops rotating, the supporting column cooperates with the positioning hole auxiliary gear and tooth plate to improve the stability of the entire structure.

[0028] (3) The device for adaptively adjusting the operating efficiency of the water pump can lift the top positioning plate by setting a telescopic support arm, which is convenient for placing the submersible pump and the L-shaped mounting frame into the well. The support arm is fixedly mounted on the top positioning plate by a rotating part, which is convenient for installation and disassembly and easy to use.

[0042] The photoelectric switch 93 is used to control the start of the motor 10. The motor 10 is a servo motor, rotates 330 degrees each time, and can rotate forward and backward. The motor 10 is powered by a storage battery, and the storage battery is fixedly installed inside the sealing cover 8. The sealing cover 8 can prevent liquid from invading the motor 10, and a protective box 92 is provided. When the submersible pump works, the pipe orifice of the extension pipe 95 is located above the liquid surface, which can prevent water from entering the protective box 92 and affecting the use of the photoelectric switch 93. At the bottom of the L-shaped mounting bracket 2, a mounting block is provided. At the bottom of the sliding rod 3, a groove is opened. The inverted L-shaped mounting brackets 2 can be spliced according to the usage situation. And at the top of the sliding rod in the inverted L-shaped mounting bracket 2, a convex shaft adapted to the groove is fixedly provided to extend the length of the sliding rod 3. And corresponding positioning holes 15 are opened on the inverted L-shaped mounting bracket 2.

[0043] The number of each group of sliding rods 3 is three. The positioning sliding sleeve 4 on the surface of the middle sliding rod includes a sliding sleeve 41.

On the other side of the connecting block 43 and inside the elastic member 44, a driving rope 45 is fixedly connected.

[0044] There is no installation shell 42, elastic member 44, support column 46, etc. in the positioning sliding sleeves on both sides, and the driving rope 45 passes through the installation shell 42 and extends to the outside of the installation shell 42.

[0045] The delay adjustment member 6 includes a driving rod 61. An adjustment shaft 62 is sleeved on the surface of the driving rod 61. A circular groove is formed in the upper side inside the adjustment shaft 62. A spiral spring 63 is fixedly connected inside the circular groove.

A first arc groove 65 is formed in one side of the inner surface of the adjustment shaft 62 and below the circular groove. A first driving block 66 is fixedly connected inside the first arc groove 65 on the surface of the adjustment shaft 62.

[0046] When the spiral spring extends normally, the first driving block 66 contacts the inner wall of the first arc groove 65 in the direction of rotation of the first driving block 66. The outer side end of the spiral spring 63 is fixed inside the circular groove. The connection between both sides of the first arc groove 65 and the center of the adjustment shaft 62 is 330 degrees.

[0047] A rotating shaft 67 is rotatably connected to the lower side of the adjustment shaft 62. One end of the rotating shaft 67 extends to the outside of the adjustment shaft 62 through a cylindrical hole. A second arc groove 69 is formed in one side of the inner surface of the cylindrical hole. A second driving block 68 is fixedly connected inside the second arc groove 69 on the surface of the rotating shaft 67.

[0048] The connection between both sides of the inner wall of the second arc groove 69 and the center of the adjustment shaft 62 is 330 degrees. When the adjustment shaft 62 rotates 60 degrees, it contacts the second driving block 68.

[0049] A winding wheel 64 is fixedly connected to the surface of the adjustment shaft 62. One ends of two driving ropes 45 are respectively fixedly connected to both sides of the surface of the winding wheel 64.

[0050] The driving member 7 includes two groups of fixed arms 71, a worm 75 and a toothed plate 73. The two groups of fixed arms 71 are respectively fixed on the surfaces of the two groups of positioning sliding sleeves 4. A rotating shaft 72 is fixedly connected between the two groups of fixed arms 71. One end of the worm 75 is fixedly installed at one end of the rotating shaft 67 through a coupling. The toothed plate 73 is fixed on one side of the inner wall of the L-shaped mounting bracket 2.

[0051] A turbine 74 is fixedly connected to the surface of the rotating shaft 72. One side of the turbine 74 meshes with the surface of the worm 75. One side of a gear 76 meshes with one side of the toothed plate 73.

[0052] The gear 76 rotates 330 degrees and travels 5 - 8 cm on the toothed plate.

[0053] A plurality of positioning holes 15 are formed on the surface of the sliding rod 3.

[0054] There are no less than 15 positioning holes 15.

[0055] The bottom of the top positioning plate 1 is fixedly connected with a telescopic support arm 14 through a rotating member 13, and a universal wheel is fixedly installed at the bottom end of the telescopic support arm 14.

[0056] The telescopic support arm 14 includes an outer cylinder and an inner arm. A nut is fixed on one side of the outer cylinder, and a threaded column is threadedly connected inside the nut. One end of the threaded column extends into the interior of the outer cylinder. A plurality of fixing holes are formed on the inner arm to position the inner wall in cooperation with the threaded column.

[0057] The rotating member 13 includes a support shaft 131. Both ends of the support shaft 131 are fixed to the bottom of the top positioning plate 1 through fixing blocks. An external threaded tube 132 is sleeved on the surface of the support shaft 131. An internal threaded tube 133 is threadedly connected to the surface of the external threaded tube 132. One end of the external threaded tube 132 and located on the surface of the support shaft 131 is fixedly connected with a rotating handle 134. A first notch 135 is formed on one side of the external threaded tube 132, and a second notch 136 is formed on one side of the internal threaded tube 133.

[0058] When the first notch 135 and the second notch 136 are in the same position, one end of the internal threaded tube 133 extends horizontally outside the external threaded tube at this time. When the two notches are staggered by 180 degrees, the rotating handle 134 is close to the external threaded tube 132 at this time.

[0059] During use, first fixedly install the submersible pump 12 inside the fixing frame 11, and then select whether to increase the length of the L-shaped mounting frame 2 according to the depth of the well. When it is necessary to increase, the mounting block at the bottom of the L-shaped mounting frame 2 can be corresponded to the mounting block at the top of another inverted L-shaped mounting frame 2 and fixedly installed through screws, and the convex shaft at the top of the sliding rod 3 on the inverted L-shaped mounting frame 2 is correspondingly inserted into the groove formed at the bottom of the sliding rod 3 on the L-shaped mounting frame 2;

[0060] When placing the submersible pump 12 into the well, first install the telescopic support arm 14 corresponding to the rotating member 13 at the bottom of the top positioning plate 1. During installation, first rotate the internal threaded tube 133 at the top of the telescopic support arm 14, and the first notch 135 on the internal threaded tube 133 corresponds to the second notch 136 on the external threaded tube 132. Then, it is sleeved on the surface of the support shaft 131 through the first notch 135 and the second notch 136. Then, drive the internal threaded tube 133 to rotate through the rotating handle 134 to stagger the first notch 135 from the second notch 136, thereby limiting it;

[0061] Then, the length of the telescopic support arm 14 can be adjusted according to the length of the entire L-shaped mounting bracket 2, and the length of the telescopic support arm 14 is adjusted to be longer than the length of the L-shaped mounting bracket 2. Then, the L-shaped mounting bracket 2 is erected through the telescopic support arm 14, and the fixing bracket 11 is located on the upper side of the wellhead. The position of the adjusting device is adjusted so that the L-shaped mounting bracket 2 corresponds to the wellhead. Then, the telescopic support arm 14 is pulled towards the side, so that the L-shaped mounting bracket 2 gradually enters the well until the water inlet of the submersible pump 12 is 10 cm below the water surface. At this time, the floating ball 94 floats on the water surface, and the top end of the extension pipe 95 is located above the water surface. Among them, the water depth inside the well is measured in advance, and the position of the fixing bracket 11 is adjusted accordingly. And when the submersible pump 12 moves to the lower side of the liquid level, at this time, the top positioning plate 1 is located at the inlet. At this time, the telescopic support arm 14 can be selected to be removed to reduce the occupied volume;

[0062] Then, the submersible pump 12 can be powered on, and the submersible pump 12 works to discharge water outward. As the water inside the well is discharged outward, the water surface drops, and the floating ball 94 moves downward accordingly. The floating ball 94 drives the shielding block 97 to move downward through the U-shaped rod 96. When the floating ball moves downward until the water inlet part of the submersible pump 12 is located below the liquid level, at this time, the shielding block 97 is located in front of the photoelectric switch 93, and at this time, the photoelectric switch 93 is triggered. The photoelectric switch 93 starts the motor 10. The motor 10 rotates 330 degrees each time. The motor 10 drives the driving rod 61, and the driving rod 61 drives the first driving block 66 at the end to rotate. The first driving block 66 drives the adjusting shaft 62 to rotate in cooperation with the side wall of the first arc-shaped groove. The adjusting shaft 62 drives the wire winding wheel 64 to wind the driving ropes on both sides, and at the same time pulls the inner end of the spring 63 to contract the spring 63;

[0063] The driving rope 45 then pulls the connecting block 43 to pull out the support column 46 from the positioning hole 15 and compress the elastic member 44. When the support column 46 is completely pulled out of the positioning hole 15, at this time, the second driving block 68 moves to contact the side wall of the second arc-shaped groove 69, and at this time, the rotating shaft 67 can be driven to rotate. The rotating shaft 67 drives the worm 75 to rotate. The worm 75 drives the rotating shaft 72 to rotate through the turbine 74. The rotating shaft 72 drives the gear 73 to rotate the gear 76 by five-sixths of a turn. Both the first arc-shaped groove 65 and the second arc-shaped groove 69 are opened to be one-sixth of a turn of the adjusting shaft 62;

[0064] At this time, the gear 76 acts with the toothed plate 73 to drive the entire driving member 7 to move downward or upward. At the same time, the positioning sliding sleeve 4 drives the fixing bracket 11 to move downward or upward, that is, drives the submersible pump 12 to move downward or upward. It moves downward until the water inlet part of the submersible pump 12 is located below the liquid level. At this time, the motor 10 stops rotating. At this time, the position of the support column 46 corresponds to the positioning hole 15. Through the action of the spring 63 and the elastic member 44, the adjusting shaft 62 rotates back to the original position. The adjusting shaft 62 drives the wire winding wheel 64 to release the driving rope 45. At this time, the support column 46 is located inside the positioning hole 15 to support it;

[0065] Similarly, when the liquid level drops again until the water inlet part of the submersible pump 12 is located below the liquid level, similarly, the driving member 7 can drive the submersible pump 12 to dive again, that is, always make the submersible pump 12 located above the liquid level, reduce the head of the pump, and increase the utilization rate of the pump.
