Description

Technical Field

[0001] This utility model relates to the field of submersible pump technology, and specifically discloses an anti-collision fixing mechanism for a submersible pump. Background Technology

[0002] Submersible pumps are essential equipment for deep well water extraction. During operation, the entire unit is submerged in water to extract groundwater to the surface. When extracting water from deep wells, the submersible pump is often lowered into the well using a wire hoisting method. To prevent the extracted groundwater from carrying sediment, submersible pumps are generally not lowered to the bottom of the well.

[0003] Existing submersible pumps are suspended during operation or hoisting, which has the following disadvantages:

[0004] 1. The submersible pump will shake during the process of entering the deep well. The shaking submersible pump will collide with the well wall, which will cause damage to the submersible pump.

[0005] 2. Submersible pumps vibrate when they are working, and the vibration of the submersible pump will cause it to shake, which will then cause it to collide with the well wall again.

[0006] 3. The supporting force of the submersible pump when it is working in the well mainly comes from the steel wire rope. If the load on the steel wire rope is too large, it will cause the steel wire rope to break. If the steel wire rope breaks, the submersible pump will sink to the bottom of the well and be lost. Utility Model Content

[0007] This utility model proposes an anti-collision fixing mechanism for a submersible pump. The protective mechanism can protect the submersible pump during its entry into a deep well, preventing collisions between the pump and the well wall and thus avoiding damage. The support and fixing mechanism can stably support and fix the submersible pump at the working point of the deep well, preventing the pump from shaking due to vibrations during operation. After being supported and fixed, the submersible pump no longer needs to be pulled by steel wire rope, effectively avoiding the breakage of the steel wire rope due to heavy load.

[0008] This utility model is implemented as follows: a submersible pump anti-collision fixing mechanism includes a submersible pump body and a mounting ring disposed outside the submersible pump body. The outer wall of the mounting ring is provided with a protective mechanism, the inside of the mounting ring is provided with a mounting mechanism, and the lower end face of the mounting ring is provided with a support fixing mechanism.

[0009] The protective mechanism includes multiple elastic telescopic rods fixedly connected to the outer wall of the mounting ring and distributed in an array, and the other end of each of the multiple elastic telescopic rods is fixedly connected to a roller;

[0010] The mounting mechanism includes two clamping plates symmetrically distributed inside the mounting ring. Two screws are threadedly connected to the outer wall of the mounting ring. One end of each screw extends into the interior of the mounting ring and is rotatably connected to the two clamping plates respectively.

[0011] The support and fixing mechanism includes multiple mounting slots fixedly connected to the lower end face of the mounting ring and arranged in an array. A rotating shaft is rotatably connected inside the mounting slot. A support rod is fixedly connected to the outer wall of the rotating shaft. A torsion spring sleeved on the outer wall of the rotating shaft is fixedly connected between the support rod and the mounting slot.

[0012] As a preferred anti-collision fixing mechanism for a submersible pump according to the present invention, the upper end face of the mounting ring is provided with a plurality of arrayed through holes, a connecting rod is fixedly connected to one side wall of each of the plurality of support rods, a first pull rope is fixedly connected to the outer wall of each of the plurality of connecting rods, the other end of each of the plurality of first pull ropes passes through the plurality of through holes and extends to the top of the mounting ring, and the other end of each of the plurality of first pull ropes is fixedly connected to a second pull rope.

[0016] As a preferred anti-collision fixing mechanism for a submersible pump according to this utility model, the clamping plate is configured with an arc-shaped structure and matches the outer wall of the submersible pump body.

[0018] The beneficial effects of this utility model are:

[0019] The elastic telescopic rods can buffer the force of impacts, thus protecting the submersible pump body and preventing it from colliding with the well wall and causing damage. After the submersible pump body is moved to the appropriate position, multiple torsion springs drive multiple support rods to rotate outward and open, so that the lower ends of the support rods abut against and insert into the well wall.

After the submersible pump body is supported and fixed, it no longer needs to be pulled by steel wire rope, effectively avoiding the breakage of steel wire rope due to heavy load.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-3 A submersible pump anti-collision fixing mechanism includes a submersible pump body 1 and a mounting ring 2 disposed outside the submersible pump body 1. The outer wall of the mounting ring 2 is provided with a protective mechanism, the inside of the mounting ring 2 is provided with a mounting mechanism, and the lower end face of the mounting ring 2 is provided with a support fixing mechanism.

[0027] The protective mechanism includes multiple elastic telescopic rods 3 that are fixedly connected to the outer wall of the mounting ring 2 and distributed in an array, and the other end of each elastic telescopic rod 3 is fixedly connected to a roller 4;

[0028] The mounting mechanism includes two clamping plates 5 symmetrically distributed inside the mounting ring 2. Two screws 6 are threadedly connected to the outer wall of the mounting ring 2. One end of each screw 6 extends into the interior of the mounting ring 2 and is rotatably connected to the two clamping plates 5 respectively.

[0029] The support and fixing mechanism includes multiple mounting slots 7 that are fixedly connected to the lower end face of the mounting ring 2 and distributed in an array. A rotating shaft 8 is rotatably connected inside the mounting slot 7. A support rod 9 is fixedly connected to the outer wall of the rotating shaft 8. A torsion spring 10 sleeved on the outer wall of the rotating shaft 8 is fixedly connected between the support rod 9 and the mounting slot 7.

[0030] In this embodiment: When in use, the mounting ring 2 is installed on the outer wall of the submersible pump body 1 through the mounting mechanism. Specifically, the mounting ring 2 is moved to the outside of the submersible pump body 1, and then the two screws 6 are rotated. The two screws 6 respectively drive the two clamping plates 5 to abut against the outer wall of the submersible pump body 1. Then, through the mutual cooperation between the two screws 6 and the two clamping plates 5, the mounting ring 2 is installed on the outer wall of the submersible pump body 1.

[0031] Then, the submersible pump body 1 and the mounting ring 2 are lowered into the deep well via the steel wire rope 15. At the same time, the second pulling rope 14 is tightened, and the submersible pump body 1 and the mounting ring 2 continue to be lowered. During the lowering process, when the submersible pump body 1 shakes and causes it to collide with the well wall, the roller 4 first comes into contact with the well wall. Through the friction between the well wall and the roller 4, the roller 4 rotates. The rotating roller 4 can reduce the friction between the elastic telescopic rod 3 and the well wall. Then the elastic telescopic rod 3 retracts to buffer the impact force, thereby protecting the submersible pump body 1 and preventing it from colliding with the well wall and causing damage to the submersible pump body 1.

[0032] After the submersible pump body 1 is moved to the appropriate position, the second pull rope 14 is released, and then multiple torsion springs 10 rebound, driving multiple support rods 9 to rotate, causing multiple support rods 9 to open outward, and thus causing the lower ends of multiple support rods 9 to abut against the well wall. At this time, multiple support rods 9 are in a downward tilted state. Since the lower ends of multiple support rods 9 are all set with barbed structures, the lower ends of support rods 9 can be inserted into the well wall through the barbed structures, thereby stably supporting and fixing the submersible pump body 1 at the working point of the deep well. This prevents the submersible pump body 1 from shaking due to the vibration generated during the operation of the submersible pump body 1. At the same time, after the submersible pump body 1 is supported and fixed, it is not necessary to continue to use the wire rope 15 for traction, effectively avoiding the wire rope 15 from breaking due to heavy load.

[0033] As a technical optimization of this utility model, the upper end face of the mounting ring 2 is provided with a plurality of arrayed through holes 11, and a connecting rod 12 is fixedly connected to one side wall of the plurality of support rods 9. A first pull rope 13 is fixedly connected to the outer wall of the plurality of connecting rods 12. The other ends of the plurality of first pull ropes 13 pass through the plurality of through holes 11 and extend to the top of the mounting ring 2. The other ends of the plurality of first pull ropes 13 are fixedly connected to a second pull rope 14.

[0034] In this embodiment, the second pull rope 14 and multiple first pull ropes 13 can pull multiple support rods 9 to rotate inward.

[0035] As a technical optimization of this utility model, the lower ends of the multiple support rods 9 are all provided with barbed structures.

[0036] In this embodiment, the lower ends of multiple support rods 9 are all provided with barbed structures. The barbed structures enable the lower ends of the support rods 9 to be inserted into the well wall, thereby enabling the submersible pump body 1 to be stably supported and fixed at the working point of the deep well.

[0037] As a technical optimization of this utility model, a steel wire rope 15 is detachably connected to the upper end face of the submersible pump body 1 via a connecting ring, and an electric wire 16 electrically connected to the submersible pump body 1 is fixedly connected to the upper end face of the submersible pump body 1.

[0038] In this embodiment: the submersible pump body 1 can be pulled by the steel wire rope 15, and the submersible pump body 1 can be supplied with electrical energy by the wire 16.

[0039] As a technical optimization of this utility model, the other ends of the two screws 6 are fixedly connected with torsion blocks 17.

[0040] In this embodiment, the torsion block 17 facilitates the rotation of the screw 6.

[0041] As a technical optimization of this utility model, the clamping plate 5 is set as an arc-shaped structure and matches the outer wall of the submersible pump body 1.

[0042] In this embodiment, the clamping plate 5 is configured as an arc-shaped structure and matches the outer wall of the submersible pump body 1, so that the clamping plate 5 can be tightly abutted against the outer wall of the submersible pump body 1, and the outer wall of the submersible pump body 1 can be stably clamped.

[0043] As a technical optimization of this utility model, the sum of the elastic forces of the multiple torsion springs 10 is less than the weight of the submersible pump body 1.

[0044] In this embodiment, the sum of the elastic forces of the multiple torsion springs 10 is less than the weight of the submersible pump body 1. When the second pull rope 14 is pulled, it will only pull the multiple support rods 9 to rotate inward, and will not pull the submersible pump body 1 upward.

[0045] The working principle and usage process of this utility model are as follows: When in use, the mounting ring 2 is moved to the outside of the submersible pump body 1, and then the two screws 6 are rotated by the two torsion blocks 17. The two screws 6 respectively drive the two clamping plates 5 to abut against the outer wall of the submersible pump body 1. Then, through the mutual cooperation between the two screws 6 and the two clamping plates 5, the mounting ring 2 is installed on the outer wall of the submersible pump body 1.

[0046] Then, the submersible pump body 1 and the mounting ring 2 are lowered into the deep well via the steel wire rope 15. At the same time, the second pulling rope 14 is tightened, and the submersible pump body 1 and the mounting ring 2 continue to be lowered. During the lowering process, when the submersible pump body 1 shakes and causes it to collide with the well wall, the roller 4 first comes into contact with the well wall. Through the friction between the well wall and the roller 4, the roller 4 rotates. The rotating roller 4 can reduce the friction between the elastic telescopic rod 3 and the well wall. Then the elastic telescopic rod 3 retracts to buffer the impact force, thereby protecting the submersible pump body 1 and preventing it from colliding with the well wall and causing damage to the submersible pump body 1.

[0047] After the submersible pump body 1 is moved to the appropriate position, the second pull rope 14 is released, and then multiple torsion springs 10 rebound, driving multiple support rods 9 to rotate, causing multiple support rods 9 to open outward, and then the lower ends of multiple support rods 9 to abut against the well wall. At this time, multiple support rods 9 are in a downward tilted state. Since the lower ends of multiple support rods 9 are all set with barbed structures, the lower ends of support rods 9 can be inserted into the well wall through the barbed structures, thereby stably supporting and fixing the submersible pump body 1 at the working point of the deep well. This prevents the submersible pump body 1 from shaking due to the vibration generated during the operation of the submersible pump body 1. At the same time, after the submersible pump body 1 is supported and fixed, it is not necessary to continue to use the wire rope 15 for traction, effectively avoiding the wire rope 15 from breaking due to heavy load.

[0048] When it is necessary to move the submersible pump body 1 downward again, pull the second pull rope 14. The second pull rope 14, together with multiple first pull ropes 13 and multiple connecting rods 12, pulls multiple support rods 9 to rotate inward, so that multiple support rods 9 are detached from the well wall. Since the sum of the elastic force of multiple torsion springs 10 is less than the weight of the submersible pump body 1, when the second pull rope 14 is pulled, only multiple support rods 9 will be pulled to rotate inward, and the submersible pump body 1 will not be pulled upward. Then, the submersible pump body 1 is lowered a certain distance through the steel wire rope 15, and is supported and fixed through the above steps.

[0049] After the submersible pump body 1 is finished using, the second pull rope 14 causes the multiple support rods 9 to rotate inward, and then the submersible pump body 1 is pulled out of the deep well by the steel wire rope 15.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
