Description

Technical Field

[0001] This utility model relates to the field of geothermal energy technology, and in particular to a medium-deep geothermal transmission device. Background Technology

[0002] Geothermal energy is the thermal energy contained within the Earth. It is characterized by sustainability, cleanliness, and high efficiency, and is a renewable energy source with great potential. Geothermal energy in the middle and deep layers usually has higher temperatures and more stable heat than that in the shallow layers. Therefore, it is necessary to ensure the safe and efficient transmission of geothermal fluids under high temperature and high pressure environments through transmission devices, while avoiding energy waste due to temperature loss or pressure reduction during transmission.

[0003] Currently, there are various types of medium-deep geothermal transmission devices on the market. However, the temperature sensors of these devices are usually installed on the outer wall of the pipe, which cannot accurately detect the temperature of the fluid inside the pipe. Furthermore, when maintenance is required, operators often need to perform complex manual operations to disassemble them. The entire operation process is cumbersome and time-consuming, increasing maintenance costs and time. Utility Model Content

[0004] This invention addresses the problem that temperature sensors in some devices on the market are usually installed on the outer wall of the pipe, making it impossible to accurately detect the temperature of the fluid inside the pipe. Furthermore, when maintenance is required, operators often need to perform complex manual operations to disassemble them, which is cumbersome and time-consuming, increasing maintenance costs and time. Therefore, this invention provides a medium-deep geothermal transport device.

[0005] This utility model is achieved by the following technical solution: a medium-deep geothermal transport device, including a limiting mechanism, an auxiliary mechanism and a protective mechanism, wherein the limiting mechanism is located inside the protective mechanism and the auxiliary mechanism is located on the surface of the protective mechanism;

[0006] The limiting mechanism includes a spring, a limiting post fixedly connected to the bottom of the spring, a connecting plate fixedly connected to the surface of the limiting post, a slider fixedly connected to one side of the connecting plate, a limiting plate slidably connected to the surface of the limiting post, a limiting ring fixedly connected to the surface of the limiting plate, a support plate fixedly connected to the inner wall of the limiting plate, and a temperature sensor fixedly connected to one side of the support plate.

[0007] Through the above technical solution, the limiting post can limit the limiting plate, thereby fixing the limiting ring. The support plate is connected between the limiting plates and can effectively support the temperature sensor.

[0008] As a further improvement to the above solution, the number of springs is set to two, and the two springs are symmetrically distributed vertically around the limiting ring.

[0009] Through the above technical solution, the symmetrically arranged springs can allow the limiting posts to limit the upper and lower limiting plates respectively, thereby further ensuring the stability of the entire device.

[0010] As a further improvement to the above solution, the slider is located to the left of the limiting post, and the temperature sensor is located to the left of the support plate.

[0011] The temperature sensor described above is a PT100 platinum resistance temperature sensor, which is suitable for a wide range of temperature changes, has high accuracy, and can provide stable temperature data.

[0012] As a further improvement to the above solution, the auxiliary mechanism includes a fixing plate, the surface of which is provided with a circular groove, and the inner wall of the circular groove is threaded with bolts.

[0013] The above technical solution provides a more robust fixing mechanism by connecting bolts to the fixing plate, thereby further ensuring the stability of the internal components of the device.

[0014] As a further improvement to the above solution, the protective mechanism includes a connecting tube, a fixing ring is fixedly connected to the surface of the connecting tube, and a fixing tube is fixedly connected to one side of the limiting ring.

[0015] Through the above technical solution, the fluid enters the interior of the fixed pipe from the connecting pipe, and the temperature sensor can directly contact the fluid to detect its temperature.

[0016] As a further improvement to the above solution, the spring is located inside the fixed ring, and the surface of the limiting post is slidably connected to the inner wall of the limiting plate.

[0017] As a further improvement to the above solution, the temperature sensor is located inside the connecting tube, and the fixing tube is located to the right of the limiting ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes a limiting mechanism. The operator first aligns the limiting ring with the groove of the connecting pipe, then moves the connecting plate by sliding the outer slider, further pushing the limiting post and compressing the spring. The limiting post slides into the fixed ring, allowing the limiting plate to fully enter the connecting pipe. The operator then releases the slider, and the spring, through its restoring force, pushes the limiting post back into the limiting plate, thus fixing the limiting ring. The support plate ensures the stability of the temperature sensor during operation. The temperature sensor can directly contact the fluid, avoiding the influence of the external environment on the measurement results and improving measurement accuracy. The installation and disassembly of the entire device are convenient and quick, further accelerating the operator's work efficiency.

[0020] This utility model, by setting an auxiliary mechanism, securely installs the fixing plate on the surfaces of the limiting ring and the fixing ring after the fixing plate comes into contact with the surface of the fixing ring through the fixing action of bolts. This further ensures the structural stability of the entire device, avoids the device from loosening due to external forces or vibrations, and further improves the actual effect.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-6 The medium-deep geothermal transport device of this embodiment includes a limiting mechanism 1, an auxiliary mechanism 2 and a protective mechanism 3. The limiting mechanism 1 is located inside the protective mechanism 3 and the auxiliary mechanism 2 is located on the surface of the protective mechanism 3.

[0032] The limiting mechanism 1 includes a spring 11, a limiting post 12 fixedly connected to the bottom of the spring 11, a connecting plate 13 fixedly connected to the surface of the limiting post 12, a slider 14 fixedly connected to one side of the connecting plate 13, a limiting plate 15 slidably connected to the surface of the limiting post 12, a limiting ring 16 fixedly connected to the surface of the limiting plate 15, a support plate 17 fixedly connected to the inner wall of the limiting plate 15, and a temperature sensor 18 fixedly connected to one side of the support plate 17. The limiting post 12 can limit the limiting plate 15, thereby fixing the limiting ring 16. The support plate 17 is connected between the limiting plates 15 and can effectively support the temperature sensor 18.

[0033] The number of springs 11 is set to two, and the two springs 11 are symmetrically distributed above and below the limiting ring 16. The symmetrical arrangement of the springs 11 allows the limiting post 12 to limit the upper and lower limiting plates 15 respectively, thereby further ensuring the stability of the entire device.

[0034] The slider 14 is located to the left of the limiting post 12, and the temperature sensor 18 is located to the left of the support plate 17.

[0035] The auxiliary mechanism 2 includes a fixing plate 21. A circular groove 22 is provided on the surface of the fixing plate 21. A bolt 23 is threadedly connected to the inner wall of the circular groove 22. The connection between the bolt 23 and the fixing plate 21 provides a more robust fixing mechanism, thereby further ensuring the stability of the internal components of the device.

[0036] The protective mechanism 3 includes a connecting pipe 31, a fixing ring 32 is fixedly connected to the surface of the connecting pipe 31, and a fixing pipe 33 is fixedly connected to one side of the limiting ring 16. Fluid enters the interior of the fixing pipe 33 from the connecting pipe 31, and the temperature sensor 18 can directly contact the fluid to detect its temperature.

[0037] Spring 11 is located inside fixed ring 32, and the surface of limiting post 12 is slidably connected to the inner wall of limiting plate 15.

[0038] Temperature sensor 18 is located inside connecting tube 31, and fixing tube 33 is located to the right of limiting ring 16.

[0039] The implementation principle of a medium-deep geothermal transmission device in this embodiment is as follows: When installing the temperature sensor 18, the operator first aligns the limiting ring 16 with the groove of the connecting pipe 31, and then inserts the limiting plate 15 into the connecting pipe 31. At this time, the spring 11 pushes the limiting post 12, preventing the limiting plate 15 from sliding completely into the connecting pipe 31. The operator needs to slide the slider 14 outward, so that the slider 14 drives the connecting plate 13 to move. Then, the moving connecting plate 13 can drive the limiting post 12 to move together, and the spring 11 will be compressed by the squeezing force. The operator can then continue to push the limiting ring 16 to push the limiting plate 15 completely into the connecting pipe 31. After that, the operator releases the slider 14, and the spring 11 can then push the limiting post 12 again, so that the limiting post 12 enters the limiting plate 15, thereby limiting and fixing the limiting ring 16. At this time, the temperature sensor 18 is... Installed inside the connecting pipe 31, the temperature of the fluid inside the pipe can be directly detected. The support plate 17 connects the upper and lower limit plates 15 and also provides effective support for the temperature sensor 18, thus ensuring the stability of the entire device during operation. After the limit ring 16 is installed, the limit ring 16 fits against the surface of the fixed ring 32. At this time, the operator places the fixed plate 21 on the fitted limit ring 16 and fixed ring 32, and places the bolt 23 inside the circular groove 22 and tightens it, so that the fixed plate 21 is fixedly installed on the surface of the fixed ring 32 and the limit ring 16, thereby limiting them and further ensuring the stability of the entire device. The whole operation process is convenient and quick, which can speed up the operator's work efficiency and further improve the overall stability of the device. The temperature sensor 18 can directly contact the fluid, thereby accurately measuring the fluid temperature, avoiding the influence of the external environment on the measurement, and further improving the actual effect.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
