Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a submersible pump cable protector which is easy to install. 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] Since the span of both ends of the submersible pump cable is large, once the cable is damaged during installation, the replacement cost is high, so it is necessary to equip the cable with a protector. In the related technology, a short section and a guard plate with claws are often used to form a protector, and the cable is passed through the protector, thereby limiting the position of the cable around the outer wall of the oil pipe to achieve the purpose of cable protection.

[0004] When the above protector is used, there is friction between the cable and the protector when the cable is threaded and pulled, which damages the cable skin. When installing the protector, it is necessary to use fasteners to fix the oil pipe, cable and protector. The mainstream fasteners are bolts, which have the defect of low protector installation efficiency.

[0005] In addition, due to the different diameters of oil pipes, in actual production activities, workers need to select protectors that are suitable for the different sizes of oil pipes. The protectors in the relevant technology are not very applicable to oil pipes of different diameters. Utility Model Content

[0006] In order to improve the situation in the related technology that the friction between the cable and the protector damages the cable skin, the protector installation efficiency is low and the applicability to oil pipes with different diameters is not strong, the present application provides a submersible pump cable protector that is easy to install to ensure that the cable skin is not damaged by the protector during the cable traction process, improves the installation efficiency of the protector by changing the fixing method of the protector, and enables the protector to be applicable to various oil pipes with different diameters within a preset diameter range, thereby improving the applicability of the protector.

[0007] The present application provides a submersible pump cable protector that is easy to install, using the following technical solution:

[0008] A submersible pump cable protector that is easy to install, comprising a connecting seat that is snap-connected to the outer wall of an oil pipe and a protective sheet that is detachably mounted on the connecting seat, the protective sheet being mounted on the connecting seat and having a cable hole for the cable to pass through, the protective sheet being "U"-shaped and the inner diameter of the protective sheet being smaller than the outer diameter of the connecting seat, plug blocks being arranged at both ends of the protective sheet, a plug hole for the plug block to be plugged into being opened on the side wall of the connecting seat, and the connecting seat and the protective sheet being made of materials having elasticity and recovery ability.

[0009] Optionally, a side of the protective sheet facing the connecting seat has a reinforcement block, and the cable hole is opened on the reinforcement block.

[0010] Optionally, the connecting seat is provided with an oil pipe hole for the oil pipe to be clamped, and the connecting seat is also provided with a make-shift opening connected to the oil pipe hole.

[0011] Optionally, a roller is provided on the end surface of the protective sheet facing the connecting seat, and the rolling surface of the roller abuts against the outer wall of the cable.

[0012] Optionally, the inner wall of the cable hole is provided with an anti-slip layer.

[0013] Optionally, a main tightening groove is provided on the side wall of the protective sheet, and the submersible pump cable protector further comprises a main tie provided along the main tightening groove.

[0014] Optionally, at least one secondary tightening groove is provided on the side wall of the protective sheet, and the secondary tightening groove is arranged parallel to the tightening groove, and the submersible pump cable protector further includes a secondary rolling belt arranged along the secondary tightening groove.

[0015] By adopting the above technical solution, when actually installing the protector, align the clearance port of the connecting seat with the oil pipe, so that the connecting seat is buckled on the oil pipe through the clearance port, and the inner wall of the oil pipe hole is against the outer wall of the oil pipe; then, buckle the protective sheet on one side of the connecting seat, so that the plug is plugged and fixed in the socket, and the cable is pulled through the cable hole, and finally the main cable tie is set on the main tightening groove and tightened. Workers can also add auxiliary cable ties according to actual work needs, set the auxiliary cable tie on the auxiliary tightening groove and tighten it. The above protector is simple and convenient to install, and the connection strength of each component of the protector is reliable. During the pulling process of the cable, one end face of the cable is against the roller surface of the roller, which makes the pulling of the cable smoother and reduces the surface wear of the cable due to friction with the protector during the pulling process.

[0016] Because the protective sheet is "U"-shaped and made of elastic and restorative materials, after the protective sheet is put on the connecting seat, the two ends of the protective sheet tend to approach each other, and the protective sheet can "hold" the connecting seat tightly. After the plug is inserted and fixed in the socket, the protective sheet and the connecting seat are not easy to loosen. Workers can choose to pull the cable first and then tie the belt, or they can choose to tie the belt first and then pull the cable. The installation order of the various components of the protector is relatively low, the operation is convenient, and the installation efficiency of the protector is improved.

[0017] In addition, the above-mentioned protector also enhances the friction between the protector and the oil pipe by arranging an anti-skid layer on the inner wall of the oil pipe hole, thereby reducing the probability of the protector being loosened and falling off the oil pipe.

[0018] When the construction site needs to repair the cable, the main rolling belt and / or the auxiliary tie are cut off, and then the protective sheet is removed from the connecting seat. The connecting seat can still be retained on the oil pipe for easy disassembly.

[0019] The protector has a forward installation state and a reverse installation state: in the forward installation state, the protective sheet is inserted from the side away from the clearance opening opened by the connecting seat; in the reverse installation state, the protective sheet is inserted from the side close to the clearance opening opened by the connecting seat. Since the connecting seat has elasticity and recovery ability, and the oil pipe hole is connected to the clearance opening, the oil pipe hole actually available for the oil pipe to be inserted is larger than the oil pipe hole in the forward installation state, so that the protector can be used for various oil pipes with different diameters within a preset diameter range, thereby improving the applicability of the protector.

[0027] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the various embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The embodiment of the utility model provides a submersible pump cable protector which is easy to install. Figures 1 to 5 As shown, it includes a connecting seat 1 clamped on the outer wall of the oil pipe and a protective sheet 2 detachably mounted on the connecting seat 1, the protective sheet 2 is mounted on the connecting seat 1 and has a cable hole 3 for the cable to pass through, the protective sheet 2 is "U"-shaped and the inner diameter of the protective sheet 2 is smaller than the outer diameter of the connecting seat 1, plug blocks 4 are arranged at both ends of the protective sheet 2, and the side wall of the connecting seat 1 is provided with a plug hole 5 for the plug block 4 to be plugged in, and the connecting seat 1 and the protective sheet 2 are both made of materials with elasticity and recovery ability.

[0029] Specifically, in this embodiment, the "U"-shaped protective sheet 2 has a notch. During installation, the notch is aligned with the connecting seat 1 that is clamped on the outer wall of the oil pipe, and the protective sheet 2 is inserted from the side of the connecting seat 1 so that the plug block 4 is inserted into the plug hole 5. Since the protective sheet 2 is made of a material with elasticity and recovery ability, after the protective sheet 2 is stretched open by the connecting seat 1, its two ends tend to approach each other, and the protective sheet 2 hugs the connecting seat 1, thereby improving the connection strength between the two.

[0030] In a preferred embodiment of the present invention, a side of the protection sheet 2 facing the connection seat 1 has a reinforcement block 6 , and the cable hole 3 is formed on the reinforcement block 6 .

[0031] In a preferred embodiment of the utility model, the connecting seat 1 is provided with an oil pipe hole 7 for clamping the oil supply pipe, and the connecting seat 1 is also provided with a clearance port 8 communicating with the oil pipe hole 7 .

[0032] Specifically, in the present embodiment, the protector has a forward installation state and a reverse installation state: in the forward installation state, the protective sheet 2 is inserted from the side away from the clearance opening 8 opened by the connecting seat 1; in the reverse installation state, the protective sheet 2 is inserted from the side close to the clearance opening 8 opened by the connecting seat 1. Since the connecting seat 1 has elasticity and recovery ability, and the oil pipe hole 7 is connected with the clearance opening 8, the oil pipe hole 7 that can actually be used for inserting the oil pipe is larger than the oil pipe hole 7 in the forward installation state, so that the protector can be used for various oil pipes with different diameters within a preset diameter range, thereby improving the applicability of the protector.

[0033] The end of the reinforcing block 6 facing the notch has a raised portion, and in the reverse installation state, the raised portion abuts against the outer wall of the oil pipe, so that the oil pipe and the cable are separated by a certain distance, thereby avoiding the friction between the cable and the oil pipe due to the close distance in the reverse installation state. The reinforcing block 6 also enhances the structural strength of the protective sheet 2, so that the protective sheet 2 is not easy to age and loosen even if it is in a long-term deformation state.

[0034] In a preferred embodiment of the present invention, a roller 9 is provided on the end surface of the protective sheet 2 facing the connecting seat 1, and the rolling surface of the roller 9 abuts against the outer wall of the cable.

[0035] Specifically, in this embodiment, during the cable pulling process, the outer wall of the cable contacts the rolling surface of the roller 9, and the roller 9 rotates as the cable slides, making the cable pulling process smoother and avoiding the wear of the surface due to friction with the protector body during the cable sliding process.

[0036] In a preferred embodiment of the present invention, an anti-slip layer 10 is provided on the inner wall of the cable hole 3 .

[0037] Specifically, in this embodiment, the anti-slip layer 10 includes a plurality of raised friction particles, which enhance the friction between the protector and the oil pipe and reduce the probability of the protector being loosened and falling off the oil pipe.

[0038] In a preferred embodiment of the utility model, a main tightening groove 11 is opened on the side wall of the protection sheet 2, and the submersible pump cable protector further includes a main tie 12 arranged along the main tightening groove 11.

[0039] Specifically, in this embodiment, the main tightening groove 11 is located in the middle of the protective sheet 2. In the forward installation state, after the protective sheet 2 is clamped on the connecting seat 1, the main cable tie 12 is put on the main tightening groove 11 and tightened. The operation is simple, which not only improves the installation efficiency of the protector, but also enhances the connection strength between the connecting seat 1 and the protective sheet 2, and the cable tie cost is relatively low.

[0040] In a preferred embodiment of the utility model, at least one auxiliary tightening groove 13 is opened on the side wall of the protective sheet 2, and the auxiliary tightening groove 13 is arranged parallel to the tightening groove. Then the submersible pump cable protector also includes an auxiliary rolling belt arranged along the auxiliary tightening groove 13.

[0041] Specifically, in this embodiment, the secondary tightening groove 13 is arranged on the side of the main tightening groove 11 away from the reinforcement block 6. In the reverse installation state, the main tightening groove 11 is away from the connecting seat 1. After the main cable tie 12 is installed, the connection strength between the connecting seat 1 and the protective sheet 2 is not high. The connection strength between the connecting seat 1 and the protective sheet 2 can be ensured by installing a secondary cable tie on the secondary tightening groove 13 and tightening it.

[0042] In summary, when actually installing the protector, align the clearance port 8 of the connection seat 1 with the oil pipe, so that the connection seat 1 is buckled on the oil pipe through the clearance port 8, and the inner wall of the oil pipe hole 7 is against the outer wall of the oil pipe; then, buckle the protective sheet 2 on one side of the connection seat 1, so that the plug block 4 is plugged and fixed in the plug hole 5, and the cable is pulled through the cable hole 3, and finally the main tie 12 is set on the main tightening groove 11 and tightened. Workers can also match the auxiliary tie according to actual work needs, and set the auxiliary tie on the auxiliary tightening groove 13 and tighten it. The above-mentioned protector is simple and convenient to install, and the connection strength of each component of the protector is reliable.

[0043] Workers can choose to pull the cable first and then tie the belt, or they can choose to tie the belt first and then pull the cable. The installation order of the various components of the protector is less demanding, further improving the convenience of installing the protector.

[0044] When the construction site needs to repair the cable, the main rolling belt and / or the auxiliary tie are cut off, and then the protective sheet 2 is removed from the connecting seat 1. The connecting seat 1 can still be retained on the oil pipe for easy disassembly.
