Description

Technical Field

[0001] The utility model relates to the field of pipeline anti-corrosion protection, in particular to a geothermal energy pipeline anti-corrosion protection device. Background Art

[0002] There are two ways to develop geothermal energy: direct utilization and indirect utilization. Direct utilization is to directly use the high-temperature formation water in the formation, and indirect utilization is to use the high-temperature formation water to heat secondary water. Based on heat exchange, the secondary water is heated to provide thermal energy. The utilization of high-temperature formation water in the formation requires burying geothermal energy pipelines in underground wells.

[0003] After searching, Chinese patent announcement number: CN219315081U discloses an underground pipeline cathodic protection and corrosion prevention device, including: an anode metal block and a connecting wire, the upper end of the anode metal block is connected to the connecting wire, and the connecting wire is connected to the surface of the pipeline; a protection mechanism, the protection mechanism is arranged on the surface of the pipeline; wherein, the protection mechanism includes a second protection component arranged on one side of the connecting wire, the second protection component is sleeved on the surface of the pipeline, the second protection component is used to wrap the connecting end of the connecting wire to prevent movement, and a first protection component is arranged on the other side of the connecting wire, and the first protection component is arranged on the surface of the pipeline.

[0004] The above patent sets a protective mechanism, which can protect the welding end of the connecting wire and the pipeline under the action of the protective mechanism. However, when the pipeline is connected to the connecting wire, in order to ensure better connectivity, a clamping mechanism is usually set between the connecting wire and the pipeline. However, after a long period of anti-corrosion protection, an anodic metal coating will appear on the outer wall of the pipeline. These coatings will cause the outer diameter of the pipeline to change. The existing clamping mechanism is usually designed for a single pipeline outer diameter size. When the outer diameter of the pipeline changes, it is necessary to replace the corresponding clamping mechanism, which increases material consumption and usage costs. For this reason, a geothermal energy pipeline anti-corrosion protection device is proposed to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The geothermal energy pipeline 19 is protected by sacrificing the anode metal block 5. It is a method of preventing metal corrosion by utilizing the principle of a primary battery, which is a prior art.

[0032] Reference Figure 2 - Figure 4 , a clamping mechanism is provided inside the mounting sleeve 1, which includes a shell 6 and a control rod 7. The shell 6 is arranged in an arc shape, and the right side of the shell 6 is fixedly connected to the inner wall of the mounting sleeve 1 through a fixing rod 15. The control rod 7 passes through and is slidably mounted on the inner wall of the shell 6. The control rod 7 has a certain curvature so that it matches the shell 6. The control rod 7 is fixedly connected to the piston plate 8. The control rod 7 is arranged in a T shape. The left side of the control rod 7 is fixedly connected to the right side of the mounting block 2. When the mounting block 2 rotates, the control rod 7 is driven to move relative to the mounting sleeve 1 and the shell 6. The piston plate 8 is mounted on the inner wall of the shell 6. The piston plate 8 is elastically connected to the inner wall of the shell 6 by a spring 9. The spring 9 is initially in a stretched state. The spring 9 applies an elastic force to the piston plate 8 in a direction away from the extrusion block 10. The piston on the inner wall of the shell 6 is connected with the extrusion block 10. A hydraulic chamber is provided between the piston plate 8 and the extrusion block 10. The hydraulic chamber inside the shell 6 is provided with oil for transmitting pressure.

[0033] Reference Figure 1 - Figure 3 The top of the pressing block 11 is provided with an inclined surface, and the pressing block 11 is squeezed and displaced when the pressing block 10 moves. The pressing block 11 is connected to the inner wall of the mounting sleeve 1 through a torsion bar spring 12. The torsion bar spring 12 is provided to make the pressing block 11 have a tendency to rotate counterclockwise. The inner wall of the pressing block 11 is rotatably connected with a rotating block 13, and the rotating block 13 can rotate slightly on the inner wall of the pressing block 11. The rotating block 13 is fixedly connected to a rubber block 14 with good elasticity on the side away from the pressing block 11, which can increase the contact friction between the pressing block 11 and the surface of the geothermal energy pipeline 19, thereby improving the stability of the clamping. The interior of the mounting sleeve 1 is provided with a positioning mechanism, and the interior of the sleeve 3 is provided with a geothermal energy pipeline 19.

[0034] Reference Figure 1 、 Figure 2 The positioning mechanism includes a positioning rod 16, which is set to a T-shape. The positioning rod 16 passes through and is slidably installed on the inner wall of the mounting sleeve 1. The sliding direction of the positioning rod 16 is left and right. The positioning rod 16 is elastically connected to the outer wall of the mounting sleeve 1 through a second spring 17. The second spring 17 is set to a stretched state. The second spring 17 applies an elastic force to the positioning rod 16 in the direction close to the mounting block 2. A positioning groove 18 that cooperates with the positioning rod 16 is provided on the right side of the mounting block 2. The number of the positioning grooves 18 is set to multiple, and the multiple positioning grooves 18 are evenly spaced and arranged on the right side of the mounting block 2.

[0035] Working principle: When in use, the mounting sleeve 1 and the mounting block 2 are mounted on the outside of the geothermal energy pipe 19, and then the positioning rod 16 is pulled to the right, so that the positioning rod 16 overcomes the elastic force of the spring 2 17 and moves to the right, thereby disengaging the positioning rod 16 from the inside of the positioning groove 18, and the mounting block 2 can be rotated clockwise relative to the mounting sleeve 1. The rotation of the mounting block 2 causes the control rod 7 to rotate clockwise. The movement of the control rod 7 drives the piston plate 8 to move toward the inside of the shell 6 and squeezes the oil in the shell 6, thereby increasing the pressure inside the hydraulic cabin, and then pushing the extrusion block 10 to move toward the outside of the shell 6. The movement of the extrusion block 10 causes the inclined surface of the extrusion block 10 to squeeze the inclined surface of the clamping block 11, thereby making the clamping block 11 Overcoming the elastic force of the torsion bar spring 12, the clockwise rotation of the compression block 11 drives the rotating block 13 to approach and press against the surface of the geothermal energy pipe 19. The rotating block 13 will rotate slightly according to the curvature of the surface of the geothermal energy pipe 19, making the clamping more stable. By arranging multiple rubber blocks 14 on the surface of the rotating block 13, the deformation of the geothermal energy pipe 19 can be reduced, and the possibility of damage to the surface of the geothermal energy pipe 19 can be reduced. At this time, the positioning rod 16 is released. The positioning rod 16 will re-enter the positioning groove 18 under the elastic force of the spring 2 17, limit the mounting block 2, and make the mounting block 2 and the mounting sleeve 1 relatively fixed, thereby improving the stability of clamping the geothermal energy pipe 19.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
