Description

Technical Field

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

[0002] The submersible pump power cable is a special cable used in conjunction with the submersible electric pump unit. It is laid in the oil well. The lower end of the cable is connected to the lead-in cable, and the upper end is connected to the ground control cabinet.

[0003] In the prior art, submersible pump cables are generally divided into two types according to their shapes: round and flat. The advantage of the flat shape is that it occupies less space. However, during power transmission, the electromagnetic induction caused by the imbalance of the magnetic field will cause hysteresis loss and make the cable heat up. Therefore, when space permits, round cables with better performance will be used. When laying the cables, the cables will be installed on the outer surface of the oil pipe with the help of cable clamps to avoid damage to the cable surface due to its own gravity or shaking. However, since the cables need to be in different shapes according to actual conditions, double cable clamps need to be purchased, which undoubtedly increases the overall procurement cost. In view of this, we propose a submersible electric pump cable protection device. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art and to provide a submersible electric pump cable protection device, which can solve the problem of needing to purchase double cable clamps due to different cable shapes.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a submersible electric pump cable protection device, comprising an oil pipe, the outer surface of the oil pipe is sleeved with a clamp, the outer surface of the clamp is fixedly connected to a U-shaped mounting plate, the right side surface of the U-shaped mounting plate is provided with a sliding groove, the right side surface of the U-shaped mounting plate is fixedly connected to two locking plates, the left side surfaces of the two locking plates are respectively fixedly connected to sliding protrusions, the sliding protrusions are adapted to the sliding grooves, the adjacent side surfaces of the two locking plates are respectively fixedly connected to two cross bars, the two cross bars are cross-arranged, bolts are respectively arranged on the front and rear side surfaces of the U-shaped mounting plate, the adjacent ends of the two bolts are respectively threadedly penetrated into the interior of the U-shaped mounting plate, the adjacent ends of the two bolts are respectively rotatably connected to the side surfaces opposite to the two locking plates, and a circular locking assembly is arranged on the outer surface of the clamp.

[0006] Preferably, the circular locking assembly comprises a mounting block, the mounting block is fixedly connected to the outer surface of the clamp, and an arc groove is formed on the left side surface of the mounting block.

[0007] Preferably, the front and rear side surfaces of the mounting block are respectively fixedly connected with second mounting blocks, the left side surface of the second mounting block is provided with a second bolt, and the second bolt thread penetrates into the interior of the clamp.

[0008] Preferably, two mounting plates are fixedly connected to the left surface of the mounting block, and a rotating rod is rotatably connected between the two mounting plates.

[0009] Preferably, a rotating sleeve is sleeved on the outer surface of the rotating rod, a locking ring is fixedly connected to the left side surface of the rotating sleeve, and the locking ring is arranged in an arc shape.

[0010] Preferably, an L-shaped plate is fixedly connected to the front surface of the locking ring, and a slot is provided on the left surface of the mounting block.

[0011] Preferably, a plug plate is fixedly connected to the right side surface of the locking ring, the plug plate is adapted to the slot, and a threaded hole extending into the interior of the slot is formed on the front side surface of the mounting block.

[0012] Preferably, the front surfaces of the L-shaped plate and the inserting plate are also provided with threaded holes, and the inner threads of the threaded holes are sleeved with third bolts.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) When fixing a flat cable, the cable protection device for the submersible electric pump passes one end of the cable between two locking plates, and then selectively rotates a bolt according to the size of the flat cable. When the bolt rotates, it gradually moves into the interior of the U-shaped mounting plate, and when the bolt moves, it synchronously drives the locking plate to move. When the locking plate moves, the two cross bars also approach each other. At the same time, when the locking plate moves, the locking plate can be limited by a sliding protrusion. After the locking plate moves, it can be tightly attached to the flat cable. When it is necessary to fix a round cable, it can be fixed with the help of a round locking assembly provided on the outer surface of the clamp. Through the above structure, when fixing cables of different shapes, different locking assemblies can be selected to complete the fixation without replacing a specific clamp, which can increase the overall applicability. Therefore, when purchasing, only one clamp needs to be purchased to selectively fix according to the actual situation.

[0015] (2) When fixing a round cable, the cable protection device for the submersible electric pump first connects the mounting block with the clamp by means of the cooperation of the second bolt and the second mounting block, then places the round cable between the arc groove and the locking ring, then rotates the locking ring so that the plug plate enters the interior of the slot, at which time the L-shaped plate is located on the front surface of the mounting block, and the three threaded holes are aligned, then the L-shaped plate, the plug plate and the mounting block are fixed by means of the third bolt. Through the above structure, not only can the clamp be used to fix the round cable, but also the mounting block can be removed as a whole when fixing the flat cable, thereby avoiding the problem that the clamp cannot be installed and fixed due to insufficient internal space.

The clamp 2 described in the text is a traditional clamp commonly used for fixing cables to oil pipes. The prior art will not be elaborated on here. When fixing the flat cable, one end of the cable is passed through between the two locking plates 5, and then the bolt 8 is selectively rotated according to the size of the flat cable. When the bolt 8 is rotated, it will gradually move into the interior of the U-shaped mounting plate 3, and when the bolt 8 moves, it will synchronously drive the locking plate 5 to move.

After the locking plate 5 moves, it can be tightly attached to the flat cable. When it is necessary to fix the round cable, it can be fixed with the help of a round locking assembly provided on the outer surface of the clamp 2. Through the above structure, when fixing cables of different shapes, different locking assemblies can be selected to complete the fixation without replacing a specific clamp, which can increase the overall applicability.

At this time, the L-shaped plate 16 is located on the front side surface of the mounting block 9, and the three threaded holes 19 are aligned, and then the L-shaped plate 16, the plug plate 18 and the mounting block 9 are fixed with the help of the third bolt 20. Through the above structure, not only the clamp 2 can fix the round cable, but also the mounting block 9 can be removed as a whole when fixing the flat cable, thereby avoiding the problem that the clamp 2 cannot be installed and fixed due to insufficient internal space.

[0026] Working principle: When fixing the flat cable, one end of the cable is passed through the two locking plates 5, and then the bolt 8 is selectively rotated according to the size of the flat cable.
