Description

Technical Field

[0001] This invention relates to the field of geothermal insulation elimination equipment, and more particularly to a geothermal insulation elimination equipment for underground pipe gallery structures. Background Technology

[0002] As the core carrier of urban infrastructure, underground utility tunnels house various pipelines such as power, communication, water supply and drainage. Their operational stability is directly related to the normal operation of the city. In the underground environment, geothermal energy can easily be conducted into the interior through the tunnel structure, causing abnormal temperature fluctuations inside the tunnel. This may not only affect the performance and service life of the pipeline materials, but also interfere with the pipeline operating parameters. Therefore, geothermal insulation and elimination equipment is needed to insulate underground utility tunnels from geothermal heat.

[0003] Currently, CN205690505U discloses a geothermal integrated utility tunnel system, comprising a utility tunnel structure buried underground and a heat pump room located above ground. Heat exchange pipes are laid within the utility tunnel structure, arranged in segments along its length, with each segment running circumferentially along the four walls of the tunnel. A heat pump unit is installed in the heat pump room, and each segment of heat exchange pipe is connected to the heat pump unit to form a loop. The heat pump unit is connected to users via heating pipes. This utility model provides a geothermal integrated utility tunnel system that solves the problem of space occupation for heat exchange pipes by arranging them in segments within the utility tunnel, effectively reducing the temperature inside the utility tunnel, and simultaneously providing efficient heating to users along the tunnel via the heat pump unit, achieving dual energy-saving and land-saving goals.

[0004] The above-mentioned scheme arranges heat exchange pipes in sections within the integrated utility tunnel, which solves the problem of the heat exchange pipes occupying space and effectively reduces the temperature inside the integrated utility tunnel. Although it can reduce the temperature inside the tunnel, there is a certain gap between the heat exchange pipes, and some geothermal heat can be transferred into the tunnel through the gap between the heat exchange pipes. There is a problem that geothermal heat cannot be blocked or eliminated. Therefore, we propose a geothermal insulation and elimination device for underground utility tunnel structures to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a geothermal insulation elimination device for underground pipe gallery structures.

The pipe gallery is located underground; the multiple cooling towers are located above ground; the multiple mounting frames are connected inside the pipe gallery; multiple geothermal insulation units are sequentially connected to the inner wall of the pipe gallery, with inlet branches connected to the inlets of each unit and return branches connected to the outlets; each geothermal insulation unit consists of multiple hollow insulation plates connected together; multiple guide plates are connected to the inner walls of the insulation plates, and circulation channels are formed between the guide plates; the flexible metal membrane is connected to the bottom of the insulation plates and the guide plates.

[0008] Preferably, multiple pipe racks are fixedly installed on the inner walls of both sides of the fixing frame, and triangular reinforcing plates are installed at the bottom of the pipe racks, and the triangular reinforcing plates are fixedly connected to the fixing frame.

[0010] Preferably, the geothermal insulation elimination device for underground pipe gallery structures further includes: a refrigerant inlet main pipe, a refrigerant recovery main pipe, multiple hoses (first type), multiple hoses (second type), and a valve body. The refrigerant inlet main pipe is installed on the ground and connected to the corresponding cooling tower via a pipe assembly; the refrigerant recovery main pipe is installed on the ground and connected to the corresponding cooling tower via a pipe assembly; one end of each hose (first type) is connected to the outlet of the refrigerant inlet main pipe, and the other end is connected to an inlet branch pipe; one end of each hose (second type) is connected to the inlet of the refrigerant recovery main pipe, and the other end is connected to a return branch pipe; the valve body is connected to the inlet branch pipe.

[0011] Preferably, multiple rigid rubber pads are installed on the side of the heat insulation plate near the fixing frame, and the rigid rubber pads are connected to the fixing frame.

[0012] Preferably, the geothermal insulation elimination device for underground pipe gallery structures further includes: an installation groove, an installation base, a hemispherical groove, a drive plate, and a hemispherical pressure seat. The installation groove is formed on a fixed frame; the installation base is connected to the heat insulation plate; the hemispherical groove is formed on the installation base; the drive plate is slidably installed in the installation groove; the hemispherical pressure seat is fixedly installed on the bottom of the drive plate, and the hemispherical pressure seat can be inserted into the corresponding hemispherical groove.

[0013] Preferably, the geothermal insulation elimination device for underground pipe gallery structures further includes: a threaded hole, a threaded rod, and an elastic washer. The threaded hole is formed on the inner wall of the mounting groove; the threaded rod is threaded into the threaded hole, with one end rotatably mounted on the drive plate and the other end fixedly mounted with a knob; the elastic washer is fitted onto the threaded rod and contacts the knob.

Each geothermal insulation unit is composed of multiple hollow insulation panels connected together. Insulation pads are set between adjacent insulation panels with no obvious gaps, which avoids the geothermal infiltration problem caused by the spacing of heat exchange pipes in the existing technology. Combined with the active heat absorption of circulating refrigerant, the geothermal heat is completely blocked and eliminated.

[0018] 2. Through the design of flexible metal film, the heat insulation board and the inner wall of the pipe gallery are tightly bonded by the refrigerant circulation pressure, eliminating the thermal resistance of the contact gap, so that the geothermal energy can be directly and efficiently transferred to the refrigerant, greatly improving the geothermal absorption and heat exchange efficiency.

[0019] 3. When the floor of the pipe gallery settles, collapses, or deforms, the insulation pad between two adjacent insulation boards and the high-strength hose connecting two adjacent insulation boards fully absorb stress through stretching, compression, or bending, ensuring that the internal circuit is unobstructed and does not break. At the same time, through the cooperation of the hemispherical pressure seat and the hemispherical groove, the insulation board and the fixing frame can rotate, thereby avoiding the breakage and damage of the insulation board caused by rigid resistance to ground deformation, thus ensuring the normal operation of the geothermal insulation unit.

[0030] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0031] This application discloses a geothermal insulation elimination device for underground pipe gallery structures.

[0032] Reference Figure 1-9A geothermal insulation and elimination device for underground pipe gallery structures includes: a pipe gallery 101, multiple cooling towers 104, multiple fixing frames 102, multiple geothermal insulation units 2, multiple guide plates 202, and a flexible metal film 204. The pipe gallery 101 is located underground; multiple cooling towers 104 are located on the ground, and are arranged at equal intervals along the length of the pipe gallery 101; multiple fixing frames 102 are connected inside the pipe gallery 101, with a support connected to the top of the fixing frame 102, and the support is integrally cast with the concrete of the pipe gallery 101. The fixing frame 102 is fixedly connected to the support, thereby increasing the stability of the fixing frame 102; multiple geothermal insulation units 2 are sequentially connected to the inner wall of the pipe gallery 101. The inlet of the geothermal insulation unit 2 is connected to an inlet branch pipe 21, and the outlet of the geothermal insulation unit 2 is connected to a return branch pipe 22. More specifically, the inlet branch pipe 21 is installed on the inlet end pipe 205 of the initial heat insulation plate 201, which is the inlet of the geothermal insulation unit 2. The return branch pipe 22 is installed on the outlet end pipe 206 at the end of the heat insulation plate 201. The liquid outlet pipe 206 is the outlet of the geothermal insulation unit 2. A geothermal insulation unit 2 is composed of multiple hollow insulation plates 201 connected together. Multiple guide plates 202 are connected to the inner wall of the insulation plates 201. The multiple guide plates 202 are configured as circulation channels 203, so that the refrigerant flows in an S-shape in the circulation channels 203. The flexible metal film 204 is fixedly connected to the bottom of the insulation plate 201 and the guide plates 202. More specifically, the flexible metal film 204 is a flexible metal film with high thermal conductivity. When the pressurized refrigerant enters the insulation plate 201, the hydraulic action will support the flexible metal film 204 at the bottom, making it bulge outward like a balloon, actively filling the unevenness and gaps on the concrete surface of the pipe gallery 101. The refrigerant's own circulation pressure is used to achieve a tight fit between the plate and the ground, eliminating the thermal resistance of the contact gaps. The geothermal heat can be transferred to the refrigerant through the flexible metal film 204.

[0033] Based on the above, and referring to Figure 1 , 2 Multiple pipe supports 103 are fixedly installed on both inner walls of the fixed frame 102 by welding. Triangular reinforcing plates are fixedly installed on the bottom of the pipe supports 103 by welding, and the triangular reinforcing plates are fixedly connected to the fixed frame 102. The stability of the pipe supports 103 can be increased by the triangular reinforcing plates.

[0034] Based on the above, and referring to Figure 4 , 7The same heat insulation pad 208 is detachably installed between two adjacent heat insulation plates 201 by screws. One side of the heat insulation plate 201 is connected to the liquid inlet pipe 205, and the other side of the heat insulation plate 201 is connected to the liquid outlet pipe 206. The same high-strength hose 207 is installed between the liquid inlet pipe 205 and the connected liquid outlet pipe 206. When the ground of the pipe gallery 101 settles, collapses or deforms, the heat insulation pad 208 between two adjacent heat insulation plates 201 and the high-strength hose 207 connecting two adjacent heat insulation plates 201 fully absorb stress through stretching, compression or bending to ensure that the internal circuit is unobstructed and does not break.

[0035] Based on the above, and referring to Figure 4 , 8 The geothermal insulation and elimination device used in the underground pipe gallery 101 structure also includes: a refrigerant inlet main pipe 105, a refrigerant recovery main pipe 106, multiple hoses 24, multiple hoses 25, and a valve body 23. The refrigerant inlet main pipe 105 is installed on the ground and connected to the corresponding cooling tower 104 via a pipe assembly. The refrigerant recovery main pipe 106 is also installed on the ground and connected to the corresponding cooling tower 104 via a pipe assembly. More specifically, the pipe assembly includes connecting pipes and a water pump, and the liquid supply method is known to those skilled in the art without inventive effort and is not within the scope of this solution, therefore it need not be described in detail. One end of each of the multiple hoses 24 is detachably and fixedly connected to the outlet of the refrigerant inlet main pipe 105 via a clamp, and the other end is detachably and fixedly connected to the inlet branch pipe 21 via a clamp. One end of each of the multiple hoses 25 is detachably and fixedly connected to the refrigerant recovery main pipe 105 via a clamp. The other end of the inlet of 06 is detachably fixed to the return branch pipe 22 by a clamp; the valve body 23 is connected to the inlet branch pipe 21. By setting the valve body 23, the flow rate entering the inlet branch pipe 21 can be controlled, thereby achieving the uniformity of the refrigerant flow rate in the geothermal insulation unit 2. When heat is blocked, the valve body 23 is opened, and the water pump installed on the cooling tower 104 injects the refrigerant into the refrigerant inlet main pipe 105 through the pipe assembly. The refrigerant inlet main pipe 105 transports the cooled refrigerant to each geothermal insulation unit 2 through the hose 24 and the inlet branch pipe 21. The refrigerant flows through the circulation channel 203 in the heat insulation plate 201 connected in sequence. The flow of the refrigerant can absorb the geothermal heat, thereby achieving the purpose of geothermal isolation and elimination.

[0036] Based on the above, and referring to Figure 3 Multiple hard rubber pads 301 are installed on the side of the heat insulation plate 201 near the fixing frame 102, and the hard rubber pads 301 are connected to the fixing frame 102. The hard rubber pads 301 can fill the gap between the heat insulation plate 201 and the fixing frame 102, thereby increasing the stability of the heat insulation plate 201.

[0037] Based on the above, and referring to Figure 9 The geothermal insulation and elimination device used in the underground pipe gallery 101 structure also includes: an installation groove 302, an installation base 303, a hemispherical groove 304, a drive plate 305, and a hemispherical pressure seat 306. The installation groove 302 is formed on the fixed frame 102; the installation base 303 is fixedly connected to the heat insulation plate 201 by welding; the hemispherical groove 304 is formed on the installation base 303; the drive plate 305 is slidably installed in the installation groove 302. More specifically, a guide hole 401 is formed on the inner wall of the installation groove 302, and a guide rod 402 is slidably installed in the guide hole 401. One end of the guide rod 402 is fixedly installed on the corresponding drive plate 305. Through the cooperation of the guide rod 402 and the guide hole 401, the drive plate 305 can be driven... The moving plate 305 guides the drive plate 305 so that it can be stably slidably installed in the mounting groove 302; the hemispherical pressure seat 306 is fixedly installed on the bottom of the drive plate 305 by welding, and the hemispherical pressure seat 306 can be inserted into the corresponding hemispherical groove 304. Through the cooperation of the hemispherical pressure seat 306 and the hemispherical groove 304, the heat insulation plate 201 and the fixing frame 102 can rotate, thereby avoiding the rigid connection between the heat insulation plate 201 and the fixing frame 102 from being damaged by ground deformation.

[0038] Based on the above, and referring to Figure 9 The geothermal insulation and elimination device used in the underground pipe gallery 101 structure also includes: threaded hole 501, threaded rod 502 and elastic gasket 504. A threaded hole 501 is formed on the inner wall of the mounting groove 302; a threaded rod 502 is threaded into the threaded hole 501, and one end is rotatably mounted on the drive plate 305. More specifically, the drive plate 305 has a rotating groove, and an annular groove is formed on the inner wall of the rotating groove. An annular seat is installed on one end of the threaded rod 502, and the annular seat is rotatably connected to the annular groove. Through the annular groove and the annular seat, the threaded rod 502 can be rotatably mounted on the drive plate 305, and the movement of the threaded rod 502 can drive the drive plate 305 to move. A knob 503 is welded and fixedly installed on the other end; an elastic washer 504 is fitted on the threaded rod 502 and contacts the knob 503. The elastic washer 504 can increase the stability of the knob 503 abutting against the fixing frame 102. The threaded rod 502 can drive the hemispherical pressure seat 306 to move and insert into the corresponding hemispherical groove 304, thereby facilitating the disassembly and assembly of the heat insulation plate 201.

[0039] The working principle of this invention is as follows: Each heat insulation plate 201 is sequentially spliced ​​together, with heat insulation pads 208 installed between adjacent heat insulation plates 201. The liquid outlet pipe 206 of the previous heat insulation plate 201 and the liquid inlet pipe 205 of the next heat insulation plate 201 are connected via a high-strength flexible hose 207 to form a geothermal insulation unit 2. The mounting base 303 is installed into the mounting groove 302 on the fixing frame 102. At this time, the flexible metal film 204 on the heat insulation plate 201 contacts the inner wall of the pipe gallery 101. By rotating the knob 503, the knob 503 drives the threaded rod 502 to rotate. The threaded rod 502 drives the drive plate 305 to move closer to the heat insulation plate 2 via threaded engagement. Moving in the direction of 01, the drive plate 305 drives the hemispherical pressure seat 306 to insert into the hemispherical groove 304 on the mounting base 303, realizing the fixed connection between the heat insulation plate 201 and the fixing frame 102. The elastic gasket 504 plays a role in preventing loosening, and the guide rod 402 ensures that the drive plate 305 slides accurately. The liquid inlet branch pipe 21 is installed on the liquid inlet end pipe 205 of the initial heat insulation plate 201, and the return branch pipe 22 is installed on the liquid outlet end pipe 206 at the end. The liquid inlet branch pipe 21 is connected to the refrigerant liquid inlet main pipe 105 through the first hose 24, and the return branch pipe 22 is connected to the refrigerant recovery main pipe 106 through the second hose 25, thus realizing the laying of the geothermal insulation unit 2.

[0040] When geothermal insulation and heat removal are required for the pipe gallery 101, valve 23 is opened. A water pump installed on the cooling tower 104 injects refrigerant into the refrigerant inlet main 105 through the piping assembly. The refrigerant inlet main 105 then delivers the cooled refrigerant to each geothermal insulation unit 2 via hose 24 and inlet branch pipe 21. The refrigerant flows through the circulation channels 203 within the insulation plates 201, which are connected sequentially. Simultaneously, when pressurized refrigerant enters the insulation plates 201, hydraulic pressure lifts the flexible metal film 204 at the bottom, causing it to bulge outwards like a balloon, actively filling the unevenness of the concrete surface of the pipe gallery 101. The gaps allow for a tight fit between the plate and the ground using the refrigerant's own circulation pressure, eliminating thermal resistance in the contact gaps. The flexible metal film 204 allows geothermal heat to be transferred to the refrigerant. After absorbing heat, the refrigerant flows into the refrigerant recovery main pipe 106 through the return branch pipe 22 and the second hose 25. It is then transported to the cooling tower 104 by the refrigerant recovery main pipe 106. The cooling tower 104 cools and releases the refrigerant. The cooled refrigerant is then pumped back to the refrigerant inlet main pipe 105 and returned to the circulation channel 203, achieving continuous heat transport and exchange, thus blocking geothermal intrusion and reducing the ambient temperature of the pipe gallery 101.

[0041] Even when the ground of the pipe gallery 101 settles, collapses, or deforms, the insulation pad 208 between two adjacent insulation panels 201 and the high-strength hose 207 connecting two adjacent insulation panels 201 fully absorb stress through stretching, compression, or bending, ensuring that the internal circuit is unobstructed and does not break. At the same time, through the cooperation of the hemispherical pressure seat 306 and the hemispherical groove 304, the insulation panel 201 and the fixing frame 102 can rotate, thereby avoiding the breakage and damage of the insulation panel 201 caused by rigid resistance to ground deformation, thus ensuring the normal operation of the geothermal insulation unit 2.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
