Description

Technical Field

[0001] The utility model relates to the technical field of geothermal conversion equipment, in particular to a geothermal conversion equipment for geothermal utilization. Background Art

[0002] With the growing global demand for clean energy, geothermal energy has attracted widespread attention as a sustainable, stable, and environmentally friendly energy source. The utilization of geothermal energy is mainly achieved through geothermal conversion equipment, which plays a vital role in the energy field.

[0003] The Earth's interior holds vast reserves of thermal energy. This energy exists in various forms within underground media, such as rocks and water layers. The core function of geothermal conversion equipment is to efficiently extract this stored underground heat and bring it to the surface, converting it into usable energy, such as electricity or hot water.

[0004] In existing technologies, geothermal conversion equipment faces many challenges in practical application. On the one hand, from the perspective of equipment placement stability, geothermal conversion equipment is usually large and heavy, requiring a stable support structure during installation and operation. However, many traditional geothermal conversion devices have shortcomings in this regard. Due to the complexity of the working environment, such as uneven ground and changing geological conditions, the main body of the equipment is prone to unstable conditions such as shaking and tilting during placement. This instability may not only affect the normal operation of the equipment, but may also cause additional stress on the pipes and connectors inside the equipment, thereby shortening the service life of the equipment.

[0005] On the other hand, in geothermal conversion equipment, the connection between fixed pipes and connecting pipes is a critical link in ensuring heat transfer and the normal operation of the entire system. These pipes are used to transport geothermal water or other heat transfer media. During long-term operation, the connection between the fixed pipes and connecting pipes is prone to loosening due to factors such as temperature changes, fluid pressure fluctuations, and vibration generated by equipment operation. Once loose, not only can the heat transfer medium leak, resulting in energy waste and environmental pollution, but it can also affect the heat exchange efficiency of the entire geothermal conversion system and reduce equipment performance. For example, geothermal water leakage may adversely affect the surrounding soil and groundwater environment. For geothermal conversion equipment used for power generation, loose connecting pipes may interrupt the heat exchange process, thereby affecting power generation efficiency.

[0006] According to the utility model patent application number CN221744161U, a new geothermal conversion device is disclosed. The device comprises a main body, a housing, an L-shaped geothermal water pipe embedded and fixed on the left side of the housing, and an inlet pipe embedded and fixed on the right side of the housing. A heat exchanger is fixedly connected between the inlet pipe and the adjacent ends of the L-shaped geothermal water pipe. While this device achieves geothermal conversion to a certain extent, it also fails to fully address the aforementioned issues of device placement stability and pipe connection stability, leaving room for improvement in practical applications. Therefore, there is a need for a geothermal conversion device for geothermal utilization that can effectively address these issues. Utility Model Content

[0007] The purpose of the utility model is to provide a geothermal conversion device for geothermal utilization, which solves the problem that the main body of the geothermal conversion device for geothermal utilization is unstable when placed during use, and the fixed pipe and connecting pipe of the geothermal conversion device for geothermal utilization are easily loose when connected, thereby causing leakage at the connection.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a geothermal conversion device for geothermal utilization, comprising a geothermal conversion device body, the lower end of the geothermal conversion device body being fixedly connected to a base, the interior of the base being slidably connected to a connecting plate, the lower end of the connecting plate being fixedly connected to a connecting rod, the connecting rod being slidably connected to the base, the lower end of the connecting rod being fixedly connected to a supporting bottom, the bottom of the supporting bottom being made of wear-resistant and non-slip rubber material, the rubber material being nitrile rubber, which has good wear resistance, oil resistance and pressure resistance, and is circular in shape, with criss-cross anti-slip grooves on the bottom, the depth of the anti-slip grooves being 3-5 mm, the width of the grooves being 2-3 mm, and the interval between adjacent grooves being 5-8 mm, which can increase the friction with the ground, improve the stability of the equipment when placed, and adapt to ground conditions under different geological conditions, including smooth cement floors, slightly undulating land, etc. The base is internally rotatably connected to a threaded rod, which is threadedly connected to the connecting plate. Preferably, a sealed bearing is provided at the connection between the threaded rod and the base. This sealed bearing is made of high-temperature, wear-resistant fluororubber seals and high-carbon chromium bearing steel. The fluororubber seal effectively prevents the ingress of impurities such as dust and moisture in a temperature range of -20°C to 200°C. The bearing steel has a hardness of HRC60-65, ensuring the wear resistance of the bearing and the smooth rotation of the threaded rod. The threaded portion of the threaded rod is coated with a special high-temperature grease. This high-temperature grease is based on a lithium-complex grease and contains solid lubricants such as graphite and molybdenum disulfide, as well as antioxidant and corrosion-resistant additives. Its dropping point is not less than 260°C and it can operate stably in high-temperature environments of 200°C. This reduces friction between the threads, improves the durability of the threaded rod during long-term use, and prevents adjustment failure caused by thread wear. A fixed tube is fixedly connected to the outside of the geothermal conversion device body. A connecting tube is slidably connected to the inside of the fixed tube. The fixed tube is provided with a limit mechanism.

[0009] Preferably, a fixing rod is fixedly connected to the inside of the base, and the fixing rod is slidably connected to the connecting plate. The design of the fixing rod can limit the connecting plate. A fixing rod is provided inside the base and slidably connected to the connecting plate to constrain the movement direction of the connecting plate. When the threaded rod is rotated to adjust the up and down position of the connecting plate, the fixing rod can ensure that the connecting plate can only move along the axial direction of the fixing rod, preventing the connecting plate from offsetting or rotating in the base. This is crucial for accurately controlling the height adjustment of the support bottom and ensuring the stability of the entire support structure. It can make the movement of the connecting plate more stable and predictable, thereby ensuring that the stability of the geothermal conversion equipment body during placement is not affected by abnormal movement of the connecting plate.

[0010] Preferably, a baffle is fixedly connected to the outer side of the threaded rod, and the baffle is in contact with the inner wall of the base. The design of the baffle can limit the threaded rod. The baffle is in contact with the inner wall of the base, which limits the threaded rod. During the rotation of the threaded rod, due to the presence of the baffle, it can limit the displacement of the threaded rod in the axial direction, preventing the threaded rod from escaping from the rotational connection between it and the base. At the same time, this limiting effect also helps to ensure the position accuracy of the threaded rod during normal operation, ensuring that the threaded transmission between it and the connecting plate can be carried out accurately and stably, thereby ensuring the reliable realization of the function of adjusting the support bottom height by rotating the threaded rod, and avoiding equipment failure or instability caused by abnormal position of the threaded rod.

[0011] Preferably, a knob is fixedly connected to the lower end of the threaded rod, and the knob is in contact with the base. The design of the knob facilitates the rotation of the threaded rod. The knob is for the operator to rotate the threaded rod conveniently. In actual operation, especially when it is necessary to fine-tune the placement height of the geothermal conversion equipment, the knob provides a location that is easy to grasp and apply force. By rotating the knob, the operator can more easily transfer torque to the threaded rod, realize the rotation of the threaded rod, and then drive the movement of the connecting plate and the support bottom. This design improves the convenience and operability of equipment adjustment, reduces the difficulty of operation and the required force, and makes the installation and adjustment process of the equipment more efficient.

[0012] Preferably, the limiting mechanism includes a mounting block, the outer side of the fixed pipe is fixedly connected to the mounting block, the outer side of the mounting block is rotatably connected to a limiting sleeve, the outer side of the geothermal conversion equipment body is fixedly connected to a guide rod, and the outer side of the connecting pipe is fixedly connected to a guide plate. By plugging the connecting pipe into the fixed pipe, the connecting pipe drives the guide plate to be socketed with the guide rod, and then the limiting sleeve is rotated to cause the limiting sleeve and the connecting pipe to undergo threaded movement, so that the limiting sleeve limits the connecting pipe, and the plugging of the connecting pipe and the fixed pipe can be kept stable.

[0013] The mounting block serves as the installation base of the limit sleeve. It connects the limit sleeve to the fixed pipe, allowing the limit sleeve to rotate around its rotation axis outside the fixed pipe, and provides stable support and positioning for the movement of the limit sleeve, ensuring that the limit sleeve will not be displaced or shaken during operation, and ensuring that the threaded connection operation between the limit sleeve and the connecting pipe can be carried out accurately.

[0014] When the connecting tube is inserted into the fixed tube, the connection between the guide plate and the guide rod provides guidance and preliminary positioning for the insertion of the connecting tube. They ensure that the connecting tube is inserted into the fixed tube in the correct direction, reducing deviation and resistance during insertion. This guiding function helps improve the accuracy and convenience of the connection operation, while also protecting the interface between the connecting tube and the fixed tube from damage caused by incorrect insertion.

[0015] The stop sleeve is threaded with the connecting pipe. When the stop sleeve is rotated, it applies a clamping force to the connecting pipe in the axial direction. This clamping force overcomes the tendency of the connecting pipe to loosen due to factors such as temperature changes, fluid pressure fluctuations, and vibration during equipment operation. It effectively secures the connecting pipe within the fixed pipe, maintains the stability of the connection, prevents leakage at the connection, and ensures the sealing and stability of the heat exchange medium transmission in the geothermal conversion equipment.

[0016] Preferably, the limiting sleeve is rotatably connected to the fixed pipe, and the limiting sleeve is connected to the connecting pipe by a thread. The design of the limiting sleeve can play a limiting role on the connecting pipe. The rotatable connection between the limiting sleeve and the fixed pipe enables the limiting sleeve to rotate freely relative to the fixed pipe while maintaining a relative position relationship with the fixed pipe. The above structure provides the necessary conditions for the threaded movement between the limiting sleeve and the connecting pipe, so that the limiting function of the connecting pipe can be achieved by rotating the limiting sleeve without affecting the position of the fixed pipe. The threaded connection between the limiting sleeve and the connecting pipe is the key to achieving the limiting effect. Through the cooperation between the threads, an axial force is generated when the limiting sleeve is rotated, which tightly fixes the connecting pipe in the fixed pipe to prevent the connecting pipe from loosening, thereby ensuring the reliability and stability of the connection and ensuring the normal operation of the internal piping system of the geothermal conversion equipment.

[0017] Preferably, an annular groove is provided inside the limiting sleeve, and the annular groove is slidably connected to the mounting block. Through the design of the annular groove, the limiting sleeve can be limited in cooperation with the mounting block. The annular groove inside the limiting sleeve is slidably connected to the mounting block, further constraining the movement of the limiting sleeve. The annular groove slides along the mounting block, limiting the freedom of the limiting sleeve in directions other than the rotation direction. This can prevent the limiting sleeve from axial movement or radial displacement during rotation, ensuring that the limiting sleeve always rotates stably around the axis of the mounting block, thereby ensuring that the threaded connection operation between the limiting sleeve and the connecting pipe can be carried out smoothly and accurately, improving the stability and reliability of the entire limiting mechanism, and helping to maintain the stability of the connection between the connecting pipe and the fixed pipe for a long time.

[0018] Preferably, the guide plate is in contact with the limiting sleeve, and the guide plate is slidably sleeved with the guide rod. The design of the guide plate can limit the connecting pipe. The guide plate is in contact with the limiting sleeve. On the one hand, during the process of inserting the connecting pipe into the fixed pipe, the cooperation with the guide rod provides a guiding effect for the connecting pipe. On the other hand, when the limiting sleeve limits the connecting pipe, the guide plate, as a part of the connecting pipe, interacts with the limiting sleeve. When the limiting sleeve rotates and holds the connecting pipe tightly, the guide plate can transmit the holding force of the limiting sleeve, so that the connecting pipe is evenly restricted in all directions, thereby more effectively preventing the connecting pipe from loosening or shaking in the fixed pipe. At the same time, the sliding sleeve structure of the guide plate and the guide rod also ensures that during the operation of the equipment, the connecting pipe can still remain in the correct position when subjected to various external forces, thereby maintaining the stability and sealing of the connection.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The utility model provides a limiting sleeve, a guide rod, a guide plate and other components. By rotating the limiting sleeve, the limiting sleeve and the connecting pipe can be threaded, so that the limiting sleeve limits the connecting pipe, and the connection between the connecting pipe and the fixed pipe can be kept stable, which solves the problem that the fixed pipe and the connecting pipe of the geothermal conversion equipment used for geothermal utilization are prone to loosening when connected, thereby causing leakage at the connection.

[0021] 2. The utility model is provided with a base, a supporting bottom, a threaded rod and other components. By rotating the threaded rod, the threaded rod and the connecting plate can undergo threaded movement, so that the connecting plate drives the supporting bottom to move, and the supporting point of the base can be adjusted, so that the main body of the geothermal conversion equipment remains stable when placed.
