Description

TECHNICAL FIELD

[0001] The utility model relates to deep well pump technical field, concretely relates to a cable protection device for deep well pump. BACKGROUND

[0002] Deep well pump is a kind of pump for pumping and transporting water by being immersed in underground water well, and the pump body is cylindrical, easy to put into narrow space, and motor and water pump are integrated, due to integrated design and the way of working into water, deep well pump is stable and reliable, and low noise. Deep well pump has no special requirements for water-lifting pipe, and is easy to install, use and maintain, and has small floor area. Deep well pump has various structural forms, including dry type, semi-dry type, oil-filled type and wet type motor. These structural forms enable deep well pump to operate efficiently in different environments. Deep well pump is not only suitable for deep water well, hot water well and ocean extraction, but also can be used for river, reservoir and water channel extraction.

[0003] The structure of deep well pump mainly comprises motor, pump body, transmission shaft, water-lifting pipe and other accessories. Deep well pump is located in deep underground, and flanges are used to connect each water-lifting pipe. The cable of deep well pump motor extends to the outside of well along the outside of water-lifting pipe. In order to avoid the cable from being hung during installation of deep well pump, the cable is usually fixed by iron wire. When the water-lifting pipe and deep well pump are taken out or put into deep well, the cable of deep well pump motor will rise with the water-lifting pipe. Since the flange is a protruding part on the water-lifting pipe, and the cable at the flange connection lacks a protection device, the water-lifting pipe collides with the wall of deep well, and the cable is squeezed or scratched, especially the cable at the flange connection, which can easily cause the cable to be worn or broken, thereby affecting the use of deep well pump and prolonging the time for taking out deep well pump. SUMMARY

[0004] The utility model aims at providing a kind of cable protection device for deep well pump to solve the problem that the cable at the flange connection lacks a protection device, which causes the cable to be damaged by collision and squeezing with deep well at the flange connection.

[0005] To achieve the above-mentioned purpose, the basic scheme provided by the utility model is as follows: a cable protection device for deep well pump, comprising a deep well, a water-lifting pipe and a cable. The water-lifting pipe is located in the deep well, and a flange is provided on the water-lifting pipe. The cable is located on the outside of the water-lifting pipe. A protective sleeve is detachably connected to the outside of the cable and the water-lifting pipe. The protective sleeve is two U-shaped clamps connected by a hinge. A limiting component is provided in the protective sleeve to prevent the protective sleeve from squeezing the cable.

[0006] The utility model discloses a principle and beneficial effect lies in: when installing, the two U type cards of horizontal rotation protective sleeve, fix protective sleeve at the water raising pipe of flange, and the cable and water raising pipe sleeve into protective sleeve, can prevent the cable of flange connecting place and deep well collision, extrusion and so on damage, then through the limiting assembly in protective sleeve, fix protective sleeve, prevent extrusion of protective sleeve and water raising pipe, cause the damage of cable, reduce the cable's collision and extrusion in the process of taking out deep well pump when replacing deep well pump, can prolong the service life of cable, and the device structure is simple, convenient operation.

[0007] Scheme two, this is the preferred basis scheme, limiting assembly includes two limiting blocks, and each limiting block and flange are opposite;Limiting block can fix protective sleeve, prevent flange connecting place and protective sleeve from shaking or extruding in the process of taking out deep well pump, cause the extrusion of cable and damage.

[0008] Scheme three, this is the preferred scheme two, protective sleeve is opened with a plurality of limiting holes, and the bolt of limiting block is fixedly connected, and the bolt is connected with the limiting hole threadedly;The thickness of flange is not fixed, and the position of limiting block can be adjusted according to actual demand, increase the practicability of the device.

[0009] Scheme four, this is the preferred basis scheme, the protective sleeve is fixedly connected with a hoop, and the cable and water raising pipe are movably connected with the hoop;The hoop can tightly fix the protective sleeve, can effectively prevent the loosening of protective sleeve due to vibration or external force, ensure the firmness of connection, when needing to maintain or replace protective sleeve, can be quickly disassembled, improve the maintenance efficiency.

[0010] Scheme five, this is the preferred basis scheme, a protective washer is arranged in the protective sleeve;The protective washer can protect the cable of flange connecting place from being damaged, since the protective sleeve is used to protect the cable from collision and extrusion, it is usually hard metal, and adding a suitable washer can reduce the direct friction between the protective sleeve and the cable, prolong the service life of the cable.

[0011] Scheme six, this is the preferred basis scheme, the protective sleeve is made of stainless steel;The stainless steel has high hardness, great strength, good wear resistance and tensile resistance, can bear greater pressure, ensure the stability of protective sleeve, can be processed with high precision by professional processing equipment and process, can effectively resist the erosion of chemical substances, moisture and oxygen in humid, acid and alkali and other harsh environments.

[0018] Example

[0019] like Figures 1 to 4 As shown: A cable protection device for a deep well pump includes a deep well 1, a water delivery pipe 2, and a cable 4. The water delivery pipe 2 is located inside the deep well 1 and is equipped with a flange 3. The cable 4 is located outside the water delivery pipe 2. A protective sleeve 5 is detachably connected to the outside of the cable 4 and the water delivery pipe 2. The protective sleeve 5 consists of two hinged U-shaped clips. A clamp 8 is fixedly connected to the protective sleeve 5. The cable 4 and the water delivery pipe 2 are movably connected to the clamp 8. A protective gasket 10 is provided inside the protective sleeve 5. A limiting component for preventing the protective sleeve 5 from squeezing the cable 4 is provided inside the protective sleeve 5. The limiting component includes two limiting blocks 6. Several limiting holes 9 are opened on the protective sleeve 5. Bolts 11 are fixedly connected to the limiting blocks 6. The bolts 11 are threadedly connected to the limiting holes 9. Each limiting block 6 abuts against the flange 3. The protective sleeve 5 is made of stainless steel.

[0020] The implementation method of this embodiment is as follows: During installation, the U-shaped clip on the protective sleeve 5 is rotated horizontally so that the protective sleeve 5 is fitted onto the flange 3 connection, covering the water pipe 2 and the cable 4. Then, the two limiting blocks 6 are adjusted so that the two limiting blocks 6 are locked onto the flange 3, thereby fixing the protective sleeve 5 and preventing the protective sleeve 5 from moving up and down. Then, the clamp 8 on the protective sleeve 5 is connected so that the protective sleeve 5 is fixed at the flange 3 connection, which can protect the cable 4. When it is necessary to replace the deep well pump, the deep well pump is taken out by the lifting device. If the water pipe 2 collides with the wall of the deep well 1, the protective sleeve 5 can prevent the cable 4 at the flange 3 connection from hitting the well wall. Then, the protective sleeve 5 is removed by the clamp 8, and then the limiting blocks 6 are removed by the bolt 11 so that the protective sleeve 5 can be removed from the flange 3, which is convenient for replacing the deep well pump.
