Description

Technical Field

[0001] This utility model belongs to the field of pipeline and pipe material design technology, specifically relating to a multi-line integrated intelligent hydropower transmission composite pipe. Background Technology

[0002] Currently, in fluidized bed mining processes or groundwater extraction activities, it is usually necessary to use submersible pumps to extract groundwater solutions or groundwater (hereinafter referred to as groundwater) from deep wells. Deep wells require the separate installation of groundwater lift pipes, power transmission cables, and water level monitoring signal lines, which presents the following problems: Traditional deep well submersible pumps require the simultaneous lowering of lift pipes and cables when extracting groundwater. To prevent the lift pipes and cables from tangling and causing blockages in the deep well, ropes and plastic adhesive tape are needed to secure the cables to the lift pipes at regular intervals. This requires multiple fixing points, is time-consuming, easily damages cables, causes environmental pollution, and can easily lead to pump jamming during drilling. Furthermore, groundwater level monitoring requires the additional installation of water level monitoring instruments, increasing the complexity of the work. Multiple reads of the water level information from the instrument are necessary, and online monitoring is not possible. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-line integrated intelligent water and electricity transmission composite pipe, which solves the problems of the need to lay out the power transmission cables, water level and other signal lines and the riser pipe separately for the pipes used for groundwater extraction in deep wells. This is because the process is complicated, the wiring cost is high, and the multiple cables are tangled and may cause safety accidents.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a multi-line integrated intelligent hydropower transmission composite pipe, wherein the composite pipe includes: a hollow cylindrical composite pipe body made of modified PE material, four axial through holes are provided in the pipe wall of the composite pipe body, a water level monitoring system is provided in one of the through holes, and the pressure data of the well water level sensor is collected in real time through a shielded twisted pair cable with built-in optical fiber, and a power transmission system is set in three axial through holes that are evenly distributed or side by side, and 380V three-phase power is transmitted through three insulated cables.

[0005] The aforementioned multi-line integrated intelligent hydropower transmission composite pipe has an outer diameter of 50-100mm and a wall thickness of 7-20mm.

[0006] In the aforementioned multi-line integrated intelligent hydropower transmission composite pipe, the insulated cable of the power transmission system is a copper core cross-linked polyethylene insulated cable, and the cable channel is sealed using a stepped sealing structure.

[0007] In the aforementioned multi-line integrated intelligent hydropower transmission composite pipe, the diameter of the axial through hole ranges from 6 to 12 mm.

[0008] The aforementioned multi-line integrated intelligent hydropower transmission composite pipe includes three axial through holes for the power transmission system. When arranged side by side, the middle through hole and the through hole for the water level monitoring system are symmetrically arranged on both sides inside the main pipe wall of the composite pipe.

[0009] In the aforementioned multi-line integrated intelligent hydropower transmission composite pipe, the three axial through holes, when arranged side by side, can also be located on the outside of the pipe wall of the composite pipe body, and fixed to the outside of the pipe wall by means of the same material as the pipe wall of the composite pipe body.

[0010] The aforementioned multi-line integrated intelligent hydropower transmission composite pipe has silicone rubber buffer layers filling the spaces between each cable.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The multi-line integrated intelligent water and electricity transmission composite pipe provided by this utility model integrates cables, signal transmission and water pipes into one unit through integrated design, which is beneficial to the pump lifting operation, improves work efficiency and shortens the pump lifting time. On the other hand, by reducing the number of procedures, the binding and dismantling of cables and water pipes during pipe lifting is eliminated, reducing material consumption and lowering the maintenance cost of single-hole failure.
