Description

Technical Field

[0001] The utility model relates to the technical field of sealing protection, in particular to a sealing protection device for a submersible electric pump cable. Background Art

[0002] Submersible electric pumps are water pumps whose impeller and the motor driving the impeller are both submerged in water. There are two types of pumps: deep well pumps and surface pumps. Deep well submersible electric pumps supply power to the motor through cables inserted into the well, eliminating the need for a long transmission shaft. Therefore, they are compact in structure, light in weight, and easy to install, use, and move. They tend to replace long-shaft deep well pumps in areas with power supply, but are not suitable for wells with high sand content and areas without power supply.

[0003] In the prior art, when the submersible pump is placed into water, it is necessary to tie the submersible pump with a rope and then slowly sink it into the water. However, when the submersible pump is placed into water, the rope and the cable may be out of sync, causing the cable to be subjected to tension, which may cause tearing at the connection between the cable and the submersible pump, affecting the sealing effect of the cable. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that, when the submersible pump is put into water, it is necessary to tie the submersible pump with a rope and then slowly sink it into the water. However, when the submersible pump is put into water, the rope and the cable may be out of sync, so that the cable is subjected to tension, which may cause the connection between the cable and the submersible pump to tear, thereby affecting the sealing effect of the cable.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sealing protection device for a submersible electric pump cable, comprising: a submersible electric pump body, a connection seat is fixedly installed on the outer surface of the submersible electric pump body near the top, and the cable body is fixedly connected inside the connection seat, and further comprising:

[0006] Two fixed plates are symmetrically fixedly installed on the outer surface of the submersible electric pump body near the top, and the outer surfaces of the two fixed plates away from the submersible electric pump body are movably embedded with rotating rods, one end of the two rotating rods is fixedly sleeved with a movable plate, the outer surfaces of the two movable plates are threadedly embedded with screws, one end of the two screws is movably sleeved with clamping plates, the outer surfaces of the two clamping plates are symmetrically fixedly installed with two guide rods, the outer surfaces of the multiple guide rods are symmetrically and movably embedded in the outer surfaces of the two movable plates in pairs, and the other ends of the two screws are fixedly installed with turning handles.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Embodiment 1, as Figure 1-5 As shown, the utility model provides a sealing protection device for a submersible electric pump cable, comprising: a submersible electric pump body 1, a connecting seat 106 is fixedly installed on the outer surface of the submersible electric pump body 1 near the top, and a cable body 102 is fixedly connected inside the connecting seat 106, and also comprises: two fixing plates 2, which are symmetrically fixedly installed on the outer surface of the submersible electric pump body 1 near the top, and the outer surfaces of the two fixing plates 2 away from the submersible electric pump body 1 are both movably embedded with rotating rods 201, one end of the two rotating rods 201 is fixedly sleeved with a movable plate 3, the outer surfaces of the two movable plates 3 are both threadedly embedded with screw rods 301, one end of the two screw rods 301 is movably sleeved with a clamping plate 304, the outer surfaces of the two clamping plates 304 are symmetrically fixedly installed with two guide rods 303, the outer surfaces of the plurality of guide rods 303 are respectively and symmetrically embedded in the outer surfaces of the two movable plates 3, and the other ends of the two screw rods 301 are both fixedly installed with a turning handle 302 , round rods 204 are fixedly installed on the opposite sides of the two fixed plates 2, and blocks 205 are movably sleeved on the outer surfaces of the two round rods 204. Limiting rings 206 are fixedly sleeved on one end of the two round rods 204. L-shaped blocks 202 are fixedly sleeved on the other ends of the two rotating rods 201. Two slots 203 are provided on one side of the two L-shaped blocks 202. The outer surfaces of the two blocks 205 are movably embedded in the inside of the two slots 203. Springs 207 are movably sleeved on the outer surfaces of the two round rods 204. One end of the two springs 207 is fixedly installed on the opposite sides of the two fixed plates 2, and the other ends of the two springs 207 are fixedly installed on one side of the two blocks 205. The two clamping plates 304 are both arranged in an arc shape. Rubber pads 305 are fixedly installed on the inner sides of the arc surfaces of the two clamping plates 304. A handle 101 is fixedly installed on the top of the submersible electric pump body 1, and the handle 101 can be connected to a rope.

[0027] In this embodiment, when the submersible electric pump body 1 and the cable body 102 need to be put into the water, first, the movable plate 3 is kept in a horizontal state, and the card block 205 is inserted into the inside of the card slot 203 to limit the L-shaped block 202. At this time, the rotating rod 201 and the movable plate 3 remain in a relatively fixed state, and then the turning handle 302 is manually turned to drive the screw rod 301 to rotate. Under the action of the threaded cooperation between the screw rod 301 and the movable plate 3 and the cooperation of the guide rod 303, the screw rod 301 can push the clamping plate 304 to move toward the outer surface of the cable body 102 and clamp it. By setting the rubber pad 305, a certain protection effect is played on the cable body 102, and by increasing the contact area with the cable body 102, when the rope and the cable body 1 02 is out of sync, the tension on the cable body 102 and the connecting seat 106 can be reduced, thereby avoiding the cable body 102 from tearing, thereby ensuring the sealing effect of the cable body 102. When the submersible pump body 1 is not in use, first release the clamping and fixation of the cable body 102, and then manually pull the block 205 to disengage it from the inside of the slot 203, and simultaneously stretch the spring 207 to release the limit on the L-shaped block 202. At this time, the movable plate 3 is rotated downward 90 degrees under the action of gravity, and then the block 205 is released. Under the reset force of the spring 207, it is inserted into the inside of another slot 203 to limit the L-shaped block 202, thereby keeping the movable plate 3 in a relatively fixed state, thereby facilitating a certain degree of storage of the device.

[0028] Embodiment 2, as Figure 1-5 As shown, a sealing sleeve 103 is fixedly sleeved on the outer surface of the connecting seat 106, and an elastic sealing ring 107 is fixedly installed on the inner wall of the sealing sleeve 103 near one end thereof, and the inner wall of the elastic sealing ring 107 is fixedly sleeved on the outer surface of the sealing sleeve 103, and an air pipe 104 is fixedly embedded on the outer surface of the sealing sleeve 103, a spherical air bag 105 is fixedly installed on one end of the air pipe 104, and an annular air bag 108 is fixedly installed on the other end of the air pipe 104, the outer surface of the annular air bag 108 is movably embedded in the inside of the sealing sleeve 103, and the inner wall of the annular air bag 108 is movably sleeved on the outer surface of the cable body 102, and the annular air bag 108, the air pipe 104 and the spherical air bag 105 are connected.

[0029] In this embodiment, when the submersible electric pump body 1 sinks into deep water, as the depth of descent increases, the pressure on the spherical airbag 105 gradually increases, causing the spherical airbag 105 to be squeezed, so that the gas inside it enters the interior of the annular airbag 108 through the air pipe 104, thereby expanding the annular airbag 108 and making it in close contact with the cable body 102. With the cooperation of the elastic sealing ring 107, water seepage at the connection between the cable body 102 and the connecting seat 106 can be avoided, thereby playing a certain sealing and protective role.

[0030] Working principle: When the submersible electric pump body 1 and the cable body 102 need to be put into the water, firstly, the movable plate 3 is kept horizontal, and the clamping block 205 is clamped into the inside of the clamping groove 203 to limit the L-shaped block 202. At this time, the rotating rod 201 and the movable plate 3 are kept relatively fixed, and then the rotating handle 302 is manually rotated to drive the screw rod 301 to rotate. Under the action of the threaded cooperation between the screw rod 301 and the movable plate 3 and the cooperation of the guide rod 303, the screw rod 301 can be pushed to clamp The plate 304 moves toward the outer surface of the cable body 102 and clamps and fixes it. By setting the rubber pad 305, it plays a certain protective role on the cable body 102 and increases the contact area with the cable body 102. In this way, when the rope and the cable body 102 are out of sync, the tension on the cable body 102 and the connecting seat 106 can be reduced, thereby avoiding the cable body 102 from being torn, thereby ensuring the sealing effect of the cable body 102. When the submersible pump body 1 is not in use, First, release the clamping fixation of the cable body 102, and then manually pull the card block 205 to disengage it from the inside of the card slot 203, and simultaneously stretch the spring 207 to release the limit of the L-shaped block 202. At this time, the movable plate 3 rotates downward 90 degrees under the action of gravity, and then releases the card block 205. Under the reset force of the spring 207, it is inserted into the inside of another card slot 203 to limit the L-shaped block 202, so that the movable plate 3 can remain in a relatively fixed state, which is convenient for certain operations on this device. When the submersible electric pump body 1 sinks into deep water, as the depth of descent increases, the pressure on the spherical airbag 105 gradually increases, causing the spherical airbag 105 to be squeezed, and the gas inside it enters the annular airbag 108 through the air pipe 104, thereby expanding the annular airbag 108 and making it in close contact with the cable body 102. With the cooperation of the elastic sealing ring 107, water seepage at the connection between the cable body 102 and the connecting seat 106 can be avoided, thereby playing a certain role in sealing protection.
