Description

Technical Field

[0001] This utility model relates to the field of energy-saving equipment technology, specifically to a special geothermal extraction and irrigation equipment for mine geothermal systems. Background Technology

[0002] Geothermal resources are a clean and renewable energy source that has been widely exploited and utilized.

[0003] Geothermal extraction and irrigation technology is a technical solution that uses pump wells to extract underground hot water to the surface, and then extracts the heat energy through heat exchange equipment to provide heating for buildings.

[0004] Because hoses can shrink and become blocked when subjected to negative pressure, rigid risers are typically used in traditional geothermal extraction and injection equipment for mines. When groundwater flows inside a rigid riser, it inevitably impacts the inner wall of the riser, causing frequent vibrations, shaking, and local bending, which in turn leads to stress concentration on the riser sidewalls and damage. Summary of the Invention

[0005] In order to overcome the problem of "vibration, swaying and local bending of riser pipe caused by water flow impact" in the above-mentioned background technology, this utility model provides a special geothermal extraction and irrigation equipment for mine geothermal.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a geothermal extraction and irrigation device for mines, including a pump module and a heat exchange module. The pump module includes a sleeve, a filter pipe, a riser, and a support assembly. The sleeve and the filter pipe are coaxially arranged and their inner cavities are interconnected. The upper part of the riser is placed in the inner cavity of the sleeve, and the lower end is placed in the inner cavity of the sleeve or the inner cavity of the filter pipe. The top end of the riser is connected to the heat exchange module through a flexible hose. The support assembly is sleeved on the outer surface of the riser. When the support assembly is subjected to vertical pressure, its diameter increases, thereby achieving contact and limiting with the inner wall of the sleeve. Several support assemblies are provided and arranged along the axial direction of the riser. Several support assemblies are sequentially pressed together from top to bottom.

[0007] As a further optimization of this utility model, the support assembly includes a first collar, a second collar, a first diagonal brace, and a second diagonal brace; the first collar and the second collar are coaxially arranged and the spacing is adjustable; the top end of the first diagonal brace is hinged to the outer wall of the first collar, the bottom end of the first diagonal brace is hinged to the top end of the second diagonal brace, and the bottom end of the second diagonal brace is hinged to the outer wall of the second collar; both the first collar and the second collar are sleeved on the outer surface of the riser and can slide.

[0008] As a further optimization of this utility model, the first diagonal brace has a limiting protrusion on the side wall near the first collar; the first diagonal brace can rotate inward until the limiting protrusion abuts against the lower middle part of the outer side wall of the first collar.

[0009] As a further optimization of this utility model, the top of the second diagonal brace away from the side wall of the second collar is provided with a guide portion, and the top of the guide portion is inclined outward and points diagonally upward.

[0010] As a further optimization of this utility model, the first diagonal brace is provided in a plurality of circular arrays with equal spacing and equal angles centered on the first collar; the second diagonal brace is provided in a plurality of circular arrays with equal spacing and equal angles centered on the second collar; the number of the first diagonal brace and the second diagonal brace are equal and they are connected in a one-to-one correspondence.

[0011] As a further optimization of this utility model, the pump well module also includes a support seat sleeved on the outer surface of the riser; the support seat is pressed against the outer edge of the bottom surface of the inner cavity of the pipe sleeve; the support seat can support the lowest support component upwards, thereby preventing it from falling into the filter pipe.

[0012] As a further optimization of this utility model, the sleeve has a multi-section tubular structure.

[0013] As a further optimization of this utility model, the sleeve includes several pipe sections that are coaxially arranged and sequentially pressed together.

[0014] As a further optimization of this utility model, an inner extension ring is provided at the bottom of the inner wall of the lowest pipe section, and the support seat is pressed onto the inner extension ring.

[0015] As a further optimization of this utility model, the inner ring body includes a first support ring, a second support ring, and a support rod. The top and bottom ends of the support rod are fixedly connected to the first support ring and the second support ring, respectively. The first support ring is sleeved on the outer surface of the riser, and the second support ring is sleeved on the outer periphery of the riser. The outer diameter of the second support ring is adapted to the outer diameter of the inner ring body.

[0016] In summary, this utility model has at least one of the following advantages:

[0017] (1) The present invention has a simple structure and reliable function. The support components are sleeved on the outer surface of the riser, and several support components are pressed together from top to bottom. After being pressed, the support components can expand and abut against the inner wall of the sleeve, thereby limiting and supporting themselves and the riser, reducing the amplitude and frequency of riser vibration and swaying, further reducing the amplitude and frequency of local bending, improving structural stability, and ensuring operational safety.

[0018] (2) The impact energy of the water flow is transmitted to the surface soil in sequence through the riser, support components and pipe sleeve, avoiding the problem of the riser being damaged due to independent absorption of impact kinetic energy in traditional technology, improving the service life of the riser and ensuring operational safety.

[0019] (3) A cover plate is pressed on the top of the uppermost support component, so that the upper middle support component expands under pressure; the outer edge of the cover plate is adapted to the inner wall of the pipe sleeve, so that when the cover plate is pressed on the support component, it can seal the pipe sleeve, thereby preventing garbage and other debris from falling into the pump well module; at the same time, when the user accidentally falls into the pipe sleeve, the support component and the cover plate can apply support force to the person, preventing them from falling further, thereby reducing the difficulty of rescue; at the same time, it can prevent the person from drowning, greatly improving the survival rate.

[0020] (4) The support base can support the lowest support component, thereby preventing the support component from falling into the filter pipe and further preventing the support component from expanding and breaking the filter pipe, thus ensuring the reliability of the filtration function.

[0041] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0042] Reference Figure 1 This embodiment provides a geothermal extraction and irrigation device specifically for mine geothermal systems, including a pump well module 1 and a heat exchange module 2. The pump well module 1 includes a pipe sleeve 11, a filter pipe 12, a riser 13, and a support assembly 14. The pump well module 1 is longitudinally inserted underground; the pipe sleeve 11 is longitudinally inserted into the topsoil 3, and the filter pipe 12 is longitudinally inserted into the aquifer 4, with the pipe sleeve 11 located above the filter pipe 12. The topsoil 3 is located above the aquifer 4, and a first water-proof layer 5 is provided between the topsoil 3 and the aquifer 4. A second water-proof layer 6 is provided below the aquifer 4. The first water-proof layer 5 and the second water-proof layer 6 are used to prevent water seepage from the aquifer 4, thereby reducing heat loss, improving the strength of the geological structure, preventing the topsoil 3 from collapsing, and improving safety.

[0043] Reference Figure 1 The sleeve 11 and the filter pipe 12 are coaxially arranged and their inner cavities are interconnected. The bottom end of the inner cavity of the filter pipe 12 is sealed to prevent impurities in the aquifer 4 from entering the inner cavity of the filter pipe 12, the inner cavity of the sleeve 11, the inner cavity of the riser 13, and the inner cavity of the heat exchange module 2 without filtration, thus avoiding blockage. The aquifer 4 is, for example, a sandstone aquifer.

[0044] Reference Figure 1 The upper part of the riser 13 is placed inside the sleeve 11, and the lower end is placed at the bottom of the sleeve 11 or the top of the filter pipe 12. The top of the riser 13 is connected to the heat exchange module 2 through a hose.

[0045] Reference Figures 1-3 The support component 14 is sleeved on the outer surface of the riser 13. When the support component 14 is subjected to vertical pressure, its diameter increases (i.e., the support component 14, which was originally in a contracted state, expands), thereby achieving contact and limiting with the inner wall of the sleeve 11. After the outer surface of the support component 14 abuts against the inner wall of the sleeve 11, it can achieve the function of limiting the riser 13, so the riser 13 cannot undergo large-amplitude, high-frequency vibration, swaying, or local bending under the impact of water flow, thus avoiding the problem of local damage.

[0046] Reference Figures 1-3 Several support components 14 are provided and arranged along the axial direction of the riser 13; several support components 14 are pressed together from top to bottom. The support component 14 located below expands due to the pressure from the support component 14 above (the pressure comes from the weight of the support component 14), so that its outer surface abuts against the inner wall of the sleeve 11.

[0047] A cover plate is pressed onto the top of the uppermost support component 14, causing the upper-middle support component 14 to expand under pressure and abut against the inner wall of the pipe sleeve 11. The cover plate is fitted around the outer periphery of the riser 13; the cover plate is connected to a rope, which can be pulled by personnel or hoisting machinery to lift the cover plate out of the pipe sleeve 11 for water sampling and other operations. The outer edge of the cover plate fits the inner wall of the pipe sleeve 11, so when the cover plate is pressed onto the support component 14, it can seal the pipe sleeve 11, thereby preventing garbage and other debris from falling into the pump well module 1; at the same time, if a user accidentally falls into the pipe sleeve 11, the support component 14 and the cover plate can provide support for the person, preventing them from falling further, thereby reducing the difficulty of rescue; at the same time, it can prevent the person from drowning, greatly improving the survival rate.

[0048] Reference Figure 2 and Figure 3The support assembly 14 includes a first collar 141, a second collar 142, a first diagonal brace 143, and a second diagonal brace 144. The first collar 141 and the second collar 142 are coaxially arranged and their spacing is adjustable. The top end of the first diagonal brace 143 is hinged to the outer wall of the first collar 141, the bottom end of the first diagonal brace 143 is hinged to the top end of the second diagonal brace 144, and the bottom end of the second diagonal brace 144 is hinged to the outer wall of the second collar 142. The support assembly 14 is rhomboid in shape, thus possessing excellent expansion capacity.

[0049] Reference Figures 1-3 The first ring 141 and the second ring 142 are both sleeved on the outer surface of the riser 13 and can slide independently along the axial direction of the riser 13.

[0050] Reference Figure 4 and Figure 5 The first diagonal brace 143 is provided in a plurality of circular arrays with equal spacing and equal angles centered on the first collar 141; the second diagonal brace 144 is provided in a plurality of circular arrays with equal spacing and equal angles centered on the second collar 142; the number of the first diagonal brace 143 and the second diagonal brace 144 are equal and they are connected in a one-to-one correspondence.

[0051] Reference Figure 3 , Figure 4 and Figure 5 The outer walls of the first ring 141 and the second ring 142 are respectively provided with a number of extended fins (for example, by integral fixed connection or by bolt fixed connection), and the extended fins are used to support the hinge shaft.

[0052] Reference Figure 3 A torsion spring is installed on the outer fin of the second ring 142. The torsion spring is sleeved on the outer circumference of the hinge shaft. One end of the torsion spring is pressed against the outer wall of the second ring 142, and the other end is pressed against the second diagonal brace 144. The torsion spring can push the second diagonal brace 144 to rotate inward, so that the support assembly 14 has a tendency to retract inward. Therefore, under the condition of no external force, the support assembly 14 can maintain its retracted shape, so that it can slide smoothly down along the sleeve 11.

[0053] During construction: The retractable support component 14 (refer to...) Figure 3 They slide down the riser 13 one by one; when multiple support components 14 are laminated, the lower support component 14 expands (see reference). Figure 2 And it comes into contact with the sleeve 11 and is limited. Finally, the cover plate is lowered along the sleeve 11, so that the cover plate presses against the uppermost support component 14, and the support component 14 in the upper middle position expands and comes into contact with the sleeve 11 and is limited.

[0054] Under the action of the torsion spring, the first diagonal brace 143 and the second diagonal brace 144 tend to rotate inward. (Refer to...) Figure 6 When the first diagonal brace 143 and the second diagonal brace 144 rotate to the inner side of the outer edge of the first collar 141 / second collar 142, excessive contraction and jamming may occur (i.e., in this state, when the first collar 141 is subjected to downward pressure, the support assembly 14 will not expand and open). To avoid this problem, refer to... Figure 3 and Figure 7 The first diagonal brace 143 has a limiting protrusion 1431 on the side wall near the first collar 141 (e.g., by an integral fixed connection or by bolts); the first diagonal brace 143 can rotate inward until the limiting protrusion 1431 abuts against the lower middle part of the outer side wall of the first collar 141, so that the angle R of the first diagonal brace 143 tilting outward is not less than 10 degrees, thereby avoiding the problem of excessive contraction.

[0055] Reference Figure 8 and Figure 9 The second diagonal brace 144 has a guide portion 1441 at its top end on the side wall away from the second collar 142. The top end of the guide portion 1441 is inclined outward and points obliquely upward. The sleeve 11 has a multi-section tubular structure. The sleeve 11 includes several coaxially arranged and sequentially pressed tube sections 111. There is a splicing seam between adjacent tube sections 111. The top end of the guide portion 1441 points obliquely upward, so that the top end of the guide portion 1441 can be prevented from being jammed by the splicing seam during the downward movement of the support assembly 14, thereby ensuring the smooth downward movement of the support assembly 14.

[0056] Reference Figure 8 The outer surface of the guide portion 1441 is provided with an elastic rubber layer 1442 (for example, by bonding or by bolting). When the support assembly 14 expands, the rubber layer 1442 adheres to and is squeezed against the inner wall of the sleeve 11, thereby avoiding the problem of vibration of the guide portion 1441 and frequent knocking of the sleeve 11, which would generate noise (when water flows in the riser 13, it causes the riser 13 to vibrate, and this vibration will be further transmitted to the entire support assembly 14).

[0057] Reference Figure 9 and Figure 10 The pump well module 1 also includes a support seat 15 sleeved on the outer surface of the riser 13; the support seat 15 is pressed against the outer edge of the bottom surface of the inner cavity of the sleeve 11; the support seat 15 can support the lowermost support component 14 upwards, thereby preventing it from falling into the filter pipe 12. The filter pipe 12 is porous and has low structural strength, so when the support component 14 expands inside the filter pipe 12, it will rupture the filter pipe 12, causing filtration failure.

[0058] Reference Figure 9 and Figure 10The inner wall of the lowest pipe section 111 has an inner extension ring 1111 (for example, by an integral fixed connection or by bolts and a sealing ring), and the support seat 15 is pressed onto the inner extension ring 1111. The upper surface of the inner extension ring 1111 is the bottom surface of the inner cavity of the sleeve 11.

[0059] Reference Figure 10 The inner ring body 1111 includes a first support ring 151, a second support ring 152 and a support rod 153. The top and bottom ends of the support rod 153 are fixedly connected to the first support ring 151 and the second support ring 152 respectively (e.g., by bolts or by an integral fixed connection). The first support ring 151 is sleeved on the outer surface of the riser 13 and can slide relative to it, so the support seat 15 can slide down the riser 13 to the bottom of the inner cavity of the sleeve 11. The second support ring 152 is sleeved on the outer periphery of the riser 13. The outer diameter of the second support ring 152 is adapted to the outer diameter of the inner extension ring 1111, so that the second support ring 152 can be located as close as possible to the outer edge of the bottom surface of the inner cavity of the sleeve 11, thereby avoiding the second support ring 152 from blocking the bottom opening of the sleeve 11, and further ensuring that the riser 13 is inserted into the middle position of the filter pipe 12, thereby reducing the problem of frequent impact between the bottom end of the riser 13 and the inner wall of the filter pipe 12, avoiding impact damage to the filter pipe 12, and improving the service life of the filter pipe 12.

[0060] Pipe section 111 is made of corrosion-resistant metal material (e.g., stainless steel) or reinforced concrete structure; filter pipe 12 is made of porous material (e.g., foamed metal, foamed ceramic, etc.), or a mesh is wrapped around the outside of the cylindrical frame to form filter pipe 12. Riser 13 is a double-layered insulated metal pipe, thereby reducing heat loss.

[0061] Reference Figure 11 Pump well modules 1 are installed in pairs. Within the same pair of pump well modules 1: one pump well module 1 is responsible for pumping water, and its internal riser 13 is the pumping riser 131; the other pump well module 1 is responsible for returning water, and its internal riser 13 is the reinjection riser 132. (Refer to...) Figure 1 and Figure 11The heat exchange module 2 includes a heat exchanger 21, a first liquid pump 22, a second liquid pump 23, an inlet pipe 24, and a return pipe 25. The heat exchanger 21 has a first inlet, a second inlet, a first outlet, and a second outlet. A heat exchange plate is installed inside the heat exchanger 21, with a first liquid path and a second liquid path on each side of the heat exchange plate. The first liquid path is connected to the first inlet and the first outlet. The first inlet is connected to the first liquid pump 22, which is connected to the inlet pipe 24, which is connected to the city heating system. The first outlet is connected to the return pipe 25, which is also connected to the city heating system. The second inlet is connected to the second liquid pump 23, which is connected to the extraction riser 131 via a flexible hose. The second outlet flexible hose is connected to the reinjection riser 132. The second liquid pump 23 uses the extraction riser 131 to pressurize the underground hot water into the heat exchanger 21 and exchange heat with the water in the urban heating system. After the underground hot water is cooled down, it is injected into the ground through the reinjection riser 132 to achieve circulation.

[0062] The heat exchanger 21, the first liquid pump 22, and the second liquid pump 23 are fixedly connected to each other by bolts. The heat exchanger 21, the first liquid pump 22, and the second liquid pump 23 are all placed on the surface of the topsoil 3.

[0063] This utility model has a simple structure and reliable function. The support component 14 is sleeved on the outer surface of the riser 13, and several support components 14 are pressed together from top to bottom. When the support component 14 is pressed, it can expand and abut against the inner wall of the sleeve 11, thereby limiting and supporting itself and the riser 13, reducing the amplitude and frequency of vibration and swaying of the riser 13, further reducing the amplitude and frequency of its local bending, improving structural stability, and ensuring operational safety.

[0064] The impact energy of the water flow is transmitted sequentially through the riser 13, the support component 14, and the sleeve 11, and finally into the surface soil 3. This avoids the problem of the riser 13 being damaged due to independently absorbing the impact kinetic energy in traditional technology, thus improving the service life of the riser 13 and ensuring operational safety.

[0065] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0066] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0067] In conclusion, for those skilled in the art, any changes, modifications, substitutions, or variations made to this utility model based on its guidance, without departing from its principles and spirit, shall still fall within the protection scope of this utility model.
