[0002] Geothermal energy is renewable heat from the Earth's interior. It originates from magma and the decay of radioactive materials. This heat is continuously transferred from the lower, high-temperature rock layers to the upper, lower, low-temperature rock layers through stratum heat conduction. Geothermal energy reserves are vast and renewable. Geothermal energy can currently be divided into two types based on its utilization: hydrothermal (water-sourced) and heat exchange (ground-sourced). Based on the depth of development and utilization, it can be further divided into shallow, intermediate, and deep geothermal.
[0003] However, in the actual use of some pipe clamps, for shallow and medium coaxial casing wells, due to the complexity of outer casing models and diameters, casing installation requires the preparation of multiple types of elevators or clamps, which is costly on the one hand and heavy on the other hand, resulting in high labor intensity for on-site operators. Therefore, in view of the above shortcomings, a pipe clamp with adjustable opening is proposed to solve the above problems. Utility Model Content

[0007] As a further description of the above technical solution:
[0008] The opening adjustment shaft is designed to be two, which can ensure that the device will not twist during use;
[0009] As a further description of the above technical solution:
[0010] There are eight fixing nuts in total, which can freely adjust the distance between the C-shaped steel clamps to accommodate the lifting and lowering of various types of pipes;
[0011] As a further description of the above technical solution:
[0012] When the flange type pipe is raised or lowered, the flange support column needs to be rotated to a vertical position and fixed;
[0013] As a further description of the above technical solution:
[0014] When the male and female buckle type pipe fixture is raised and lowered, the flange support column needs to be rotated, laid flat and fixed.
[0015] The utility model has the following beneficial effects:

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.
[0026] Reference Figures 1 to 3 The utility model provides an embodiment: a lower pipe clamp with adjustable opening, comprising two C-shaped steel clamps 1, which play a vital role in this device. It is made of high-strength steel and has good rigidity and stability. Its unique C-shaped design can fit tightly to the outer surface of the pipe fixture, providing reliable support for the lifting and lowering of the pipe fixture. The size of the C-shaped steel clamp 1 has been carefully designed and is suitable for various types of pipe fixtures within DN150mm. Whether it is a flange-type pipe fixture 5 or a male and female buckle-type pipe fixture 6, it can be safely lifted and lowered under the clamping of the C-shaped steel clamp 1. The tops of the two C-shaped steel clamps 1 are rotatably connected to a flange support column 2. The main function of the flange support column 2 is to provide specific support when the bolts of the flange-type pipe fixture 5 are disassembled.
[0027] Reference Figures 2 to 4 When the flange-type pipe fixture 5 is being lifted and lowered, the flange support column 2 needs to be rotated to a vertical position and fixed. This ensures that the flange support column 2 is in close contact with the flange portion of the pipe fixture, providing stable support for bolt removal. The top of the flange support column 2 is provided with a connection structure that matches the flange-type pipe fixture 5, which can ensure the safety and stability of the pipe fixture during the lifting and lowering process. At the same time, the rotational connection design of the flange support column 2 and the C-shaped steel clamp 1 allows it to be flexibly adjusted according to the operation requirements and is convenient for operation. The two C-shaped steel clamps 1 are internally slidably connected with two opening adjustment shafts 3. The opening adjustment shafts 3 are designed to be two, which can ensure that the device will not twist during use. The function of the opening adjustment shaft 3 is to adjust the distance between the C-shaped steel clamps 1 by adjusting its position inside the C-shaped steel clamp 1, thereby adapting to the lifting and lowering operations of different types of pipe fixtures. The design of the two opening adjustment shafts 3 can ensure that the device will not twist during use, ensuring the safe and stable lifting and lowering of the pipe fixture. The exteriors of both adjustment shafts 3 are threadedly connected to multiple fixing nuts 4. There are eight fixing nuts 4, allowing for flexible adjustment of the distance between the C-shaped steel plates 1 to accommodate the lifting and lowering of various pipe types. The main function of the fixing nuts 4 is to secure the adjustment shafts 3 in place through their threaded connection with the adjustment shafts 3, thereby adjusting the distance between the C-shaped steel plates 1 to accommodate the lifting and lowering of various pipe types. The eight fixing nuts 4 provide sufficient adjustment accuracy and stability.
[0028] Reference Figures 4 to 6 During use, operators can flexibly adjust the position of the fixing nut 4 based on the diameter and type of the pipe, ensuring that the C-shaped steel clamp 1 can tightly grip the pipe and ensuring safe and stable lifting and lowering operations. A flange-type pipe fixture 5 is installed on the top of the flange support column 2. When the flange-type pipe fixture 5 is being raised or lowered, the flange support column 2 needs to be rotated to a vertical position and secured. The flange-type pipe fixture 5 typically has a flange connection structure, and the flange support column 2 needs to be rotated to a vertical position and secured during the lifting and lowering process. This provides stable support for the bolt removal of the flange-type pipe fixture 5, ensuring safe operation. A male and female buckle-type pipe fixture 6 is installed on the top of the two C-shaped steel clamps 1. When the male and female buckle-type pipe fixture 6 is being raised or lowered, the flange support column 2 needs to be rotated flat and secured. The male and female buckle-type pipe fixture 6 uses a male and female buckle connection, and the flange support column 2 needs to be rotated flat and secured during the lifting and lowering process. This prevents the flange support column 2 from interfering with the lifting and lowering operation of the male and female buckle-type pipe fixture 6, improving operational efficiency.
[0029] Working principle: A lower pipe clamp with adjustable opening mainly consists of two C-shaped steel clamps 1, flange support columns 2, opening adjustment shafts 3 and fixing nuts 4. The C-shaped steel clamp 1 is made of high-strength steel, and its unique C-shaped design can fit tightly to the outer surface of various types of pipes within DN150mm, providing reliable support for the lifting of pipes. The flange support column 2 is rotatably connected to the top of the C-shaped steel clamp 1. When the bolts of the flange-type pipe fixture 5 are removed, it can be rotated to a vertical state and fixed to provide stable support for the flange part; for the male and female buckle-type pipe fixture 6, it is rotated flat to avoid interference when it is lifted. There are two opening adjustment shafts 3, which are slidably connected to the inside of the C-shaped steel clamp 1. By adjusting its position, the distance between the C-shaped steel clamps 1 can be adjusted to adapt to different types of pipes, and it can ensure that the device does not twist during use. Eight fixing nuts 4 are threaded onto the opening adjustment shaft 3, securing the shaft 3 in a specific position. Operators can flexibly adjust the position of the fixing nuts 4 according to the diameter and type of pipe, ensuring that the C-shaped steel clamp 1 tightly grips the pipe, ensuring safe and stable lifting and lowering operations. This pipe lowering clamp combines the characteristics and functions of various structures to achieve safe and efficient lifting and lowering operations for different types of pipes.
[0030] 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. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
