[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 7 As shown, an embodiment of the utility model provides a tunnel cooling device, which includes a circulation pipeline 4, an installation box 1, and an air guide structure 2 and a blowing assembly 3 arranged in the installation box 1, the installation box 1 has a relative air inlet side and an air outlet side, the blowing direction of the blowing assembly 3 is from the air inlet side to the air outlet side, and the air guide structure 2 and the blowing assembly 3 are arranged in the installation box 1 at intervals along the blowing direction; the circulation pipeline 4 includes a heat exchange pipeline 41 and a drainage pipeline 42 that are interconnected, the heat exchange pipeline 41 is arranged around the air guide structure 2, the blowing assembly 3 is arranged on the drainage pipeline 42, and the cold flow flowing through the drainage pipeline 42 provides driving force for the blowing assembly 3.

[0029] In this embodiment, the cooling water first flows through the heat exchange pipeline 41, so that the heat exchange pipeline 41, the air guide structure 2 surrounded by the heat exchange pipeline 41 and the surrounding area are cooled and a cold flow atmosphere is formed. Then the cooling water continues to flow to the drainage pipeline 42. In the process of flowing through the drainage pipeline 42, the blowing component 3 is driven to start and generate wind flow. The wind flow passes through the cold flow atmosphere in the process of flowing along the blowing direction, so as to blow the cold flow in the area out from the air outlet side of the installation box 1 to cool down the tunnel. In this arrangement, the cooling water is used to form a cold flow atmosphere and drive the blowing component 3 to work. There is no need to set up a motor or other additional power source and there is no need to lay cables or other additional pipelines. The equipment cost is reduced on the basis of ensuring the cooling effect on the tunnel. The tunnel cooling device is safer and the installation position is more selective and the installation convenience is higher.

[0030] like Figure 2 , Figure 4 and Figure 5 As shown, the blowing assembly 3 includes a fixed box 8 and a fan blade assembly, the fan blade assembly is rotatably arranged on the fixed box 8 to form a wind flow from the air inlet side to the air outlet side, the fixed box 8 is arranged in the installation box 1 and has a liquid flow channel 11 connected to the drainage pipeline 42, and the part of the fan blade assembly located in the fixed box 8 has a plurality of striking ends, and the plurality of striking ends can be rotatably arranged around the axis of the fan blade assembly, and any striking end will pass through the liquid flow channel 11 during the rotation process. This arrangement facilitates the rotation drive of the fan blade assembly by the fluid flowing through the liquid flow channel 11, thereby ensuring the blowing effect.

[0031] like Figure 4 and Figure 5 As shown, the fan blade assembly includes a first rotating shaft 9, a second rotating shaft 13, a blade group and a fan blade group. The first rotating shaft 9 and the second rotating shaft 13 are connected and rotatably penetrated on the fixed box 8. The ends of the first rotating shaft 9 and the second rotating shaft 13 that are opposite to each other are respectively located inside and outside the fixed box 8. The fan blade group includes a plurality of fan blades 10 and are arranged at the end of the second rotating shaft 13 that is located outside the fixed box 8. The blade group includes a plurality of blades 14 and are arranged at the end of the first rotating shaft 9 that is located inside the fixed box 8. The end of any blade 14 that is opposite to the first rotating shaft 9 forms a striking end.

[0032] In this embodiment, the first rotating shaft 9 is rotatably arranged on the side wall of the fixed box 8 facing the air outlet side, and the second rotating shaft 13 is rotatably arranged in the fixed box 8 and connected to the first rotating shaft 9. The circulating coolant flowing through the drainage pipe 42 will cause an impact on the striking end of the blade 14 located in the liquid flow channel 11 during the process of flowing through the liquid flow channel 11, so that the blade group rotates. As the circulating coolant continues to flow, the blade group will continue to rotate under the impact, and the blade group rotates and drives the second rotating shaft 13, the first rotating shaft 9 and the fan blade group to rotate, and the fan blade group rotates to form a wind flow. In this way, the fan blade assembly is continuously driven to rotate and form a wind flow by the circulating coolant, and there is no need to set up a motor or other additional power source, cable and additional pipeline, which is safer to use and easy to design and install.

[0033] like Figure 5 As shown, the fixed box 8 has a mounting cavity 12, and the striking end is limitedly matched with the inner wall of the mounting cavity 12 during the rotation process, and the liquid flow channel 11 passes through the bottom area of ​​the mounting cavity 12. This arrangement can limit the rotation of the blade group in the fixed box 8 to prevent the blade group from moving or deflecting during the rotation process. At the same time, the liquid flow channel 11 is arranged to pass through the bottom area of ​​the mounting cavity 12, which is conducive to ensuring the retention of the circulating coolant in the fixed box 8 and the driving effect of the circulating coolant on the blade group.

[0034] like Figure 2 and Figure 3 As shown, the heat exchange pipeline 41 is a serpentine flat tube with multiple parallel sub-flow paths. The heat exchange pipeline 41 is meandering to form multiple installation areas, and the multiple installation areas are spaced apart from each other and located on the same vertical plane. The air guide structure 2 includes multiple air guide and heat dissipation components 5, and a corresponding air guide and heat dissipation component 5 is inserted in any installation area. Such a setting is conducive to increasing the amount of cooling water flowing through the heat exchange pipeline 41, and at the same time, it is conducive to increasing the cooling area and cooling effect of the heat exchange pipeline 41 on the nearby area and nearby structures, and is conducive to expanding the cold flow atmosphere and ensuring the coldness of the cold flow atmosphere. By setting up multiple air guide and heat dissipation components 5, it is conducive to further expanding the surrounding area and cooling range of the heat exchange pipeline 41, and is conducive to further improving the range and continuous stability of the cold flow atmosphere. Among them, the heat exchange pipeline 41 in this embodiment has 3 parallel sub-flow paths, and the heat exchange pipeline 41 in this embodiment is formed with 5 installation areas. The openings of any two adjacent installation areas are opposite, and correspondingly, there are 5 air guide and heat dissipation components 5, and the 5 air guide and heat dissipation components are inserted in the 5 installation areas one by one.

[0035] like Figure 7As shown, the air-guiding heat dissipation assembly 5 includes a vertical plate group and a plurality of horizontal plate groups. The vertical plate group includes a plurality of vertical plates 17. The plurality of vertical plates 17 are parallel to each other and are evenly spaced in pairs. A horizontal plate group is provided between any two vertical plates 17. The horizontal plate group includes a plurality of horizontal plates 18. The plurality of horizontal plates 18 are parallel to each other and are evenly spaced in pairs along the extension direction of the vertical plates 17. A plurality of airflow channels 19 are formed between any two adjacent vertical plates 17 through the horizontal plate group. In this way, the wind flow is easily guided through the plurality of airflow channels 19, which ensures the uniform distribution of the wind flow and is conducive to maintaining the cold flow atmosphere. It can be understood that the cold flow atmosphere will continue with the flow of cooling water to ensure that the wind flow can always blow out the cold flow from the wind outlet side. The wind flow is evenly diverted through the plurality of airflow channels 19 to avoid the situation where the wind flow is too concentrated, resulting in a faster cold flow loss in the area where the wind flow blows through, and the cooling water is difficult to maintain the cold flow atmosphere in this part. On the other hand, the orientation of the plurality of airflow channels 19 formed inside the vertical plate group and the horizontal plate group can be determined according to the actual situation, and is not limited to the parallel arrangement in this embodiment.

[0036] like Figure 3 and Figure 7 As shown, the vertical plate 17 is arranged vertically and parallel to the blowing direction, and multiple slot groups are arranged on both the upper and lower sides of the vertical plate group. The multiple slot groups are arranged at intervals along the blowing direction. Any slot group includes multiple slots 20 arranged on multiple vertical plates 17 in a one-to-one correspondence. The upper and lower side walls of the heat exchange pipeline 41 are provided with multiple convex strips 21. The multiple convex strips 21 correspond to the multiple slot groups in a one-to-one correspondence. The convex strips 21 in any installation area are limitedly matched with the corresponding slot group. This arrangement facilitates the plugging and unplugging of the air-guiding and heat-dissipating component 5 in the installation area of ​​the heat exchange pipeline 41, avoids other relative movements between the air-guiding and heat-dissipating component 5 and the heat exchange pipeline 41 other than plug-in, and ensures the reliability and stability of the installation of the two.

[0037] like Figure 2 As shown, there are multiple blowing assemblies 3, and multiple blowing assemblies 3 are connected in series on the drainage pipeline 42 in sequence. Multiple blowing assemblies 3 are located on the same vertical plane and the blowing directions are parallel to each other; an air guide structure 2 and the corresponding heat exchange pipeline 41 form a cold atmosphere group, and there are multiple cold atmosphere groups, and multiple cold atmosphere groups are arranged at intervals along the blowing direction, and multiple heat exchange pipelines 41 of multiple cold atmosphere groups are connected in sequence. Such an arrangement is conducive to improving the coverage range of the wind flow and the coverage range of the cold flow atmosphere, so as to improve the cooling effect of the lane cooling device on the lane. Among them, there are 4 blowing assemblies 3 in this embodiment, and the 4 blowing assemblies 3 are distributed in a rectangular shape. There are 2 cold atmosphere groups in this embodiment, and the two cold atmosphere groups are arranged at intervals along the blowing direction.

[0038] like Figure 6As shown, a first mounting frame 15 and a second mounting frame 16 are provided inside the mounting box 1 . The first mounting frame 15 is used to support the blowing assembly 3 , and the second mounting frame 16 is used to support the heat exchange pipeline 41 and the air guide structure 2 .

[0039] In this way, the first mounting frame 15 and the second mounting frame 16 facilitate the support of the blowing assembly 3 and the cold atmosphere group. The number of the first mounting frame 15 and the number of the second mounting frame 16 are determined according to the number of the blowing assembly 3 and the cold atmosphere group. For example, in this embodiment, there are two first mounting frames 15, each of which supports two blowing assemblies, and there are two second mounting frames 16, one of which supports one cold atmosphere group.

[0040] like Figure 1 and Figure 2 As shown, the ends of the heat exchange pipeline 41 and the drainage pipeline 42 that are away from each other are the water inlet pipe section 6 and the water outlet pipe section 7, respectively. The water inlet pipe section 6 and the water outlet pipe section 7 are both penetrated on the side wall of the installation box 1. The air inlet side and the air outlet side of the installation box 1 are both installed with a protective plate 22, and the protective plate 22 has evenly distributed grid holes, which are used for air flow. In this way, the protection of the internal area of ​​the installation box 1 is achieved through the protective plate 22, which is conducive to improving the reliability and safety of the tunnel cooling device. Among them, the cooling water enters from the water inlet pipe section 6 and flows out from the water outlet pipe section 7. The water outlet pipe section 7 and the water inlet pipe section 6 in this embodiment are penetrated on the same side wall and are respectively located at the upper and lower diagonals of the side wall of the installation box 1. It is understandable that the protective plate 22 can also be a structure such as an isolation net with a certain structural strength. Examples are not given here one by one. The cooling water can be recycled through a circulating pump after cooling. The outlet pipe section 7 passes through the normal temperature groundwater layer and is connected to the water inlet of the circulating pump installed on the ground. The inlet pipe section 6 is connected to the water outlet of the circulating pump, and the cooling speed of the tunnel cooling device on the tunnel can also be achieved by controlling the speed of the circulating pump. The circulating pump and the control system for controlling the circulating pump are generally set in a safe position on the ground. The tunnel cooling device does not need to be equipped with a motor or other additional power source, and there is no risk of electric shock to personnel, and the risk of explosion caused by electric sparks can be reduced. Therefore, the device is safer to use. At the same time, since no additional power supply equipment is used and no wiring is required, the installation location of the tunnel cooling device can be more selective. It only needs a location where a water pipe can be installed, which is convenient for the installation of the tunnel cooling device.

[0041] In summary, the utility model provides a tunnel cooling device, the working principle of which includes:

[0042] When in use, cooling water flows into the heat exchange pipeline 41 from the water inlet pipe section 6, and flows through two cold atmosphere groups in sequence, cooling the heat exchange pipeline 41, multiple air-guiding and heat-dissipating components 5 surrounded by the heat exchange pipeline 41, and nearby areas to form a cold flow atmosphere. Then, the cooling water with a slightly lowered temperature enters the drainage pipeline 42 and flows through four blowing components 3 in sequence. The cooling water flows through the blowing components 3 and drives the blowing components 3 to rotate to form a wind flow, which blows from the air inlet side to the air outlet side. When passing through the cold atmosphere group, the wind flow will take away part of the cold flow in the cold flow atmosphere and blow the cooling air out from the air outlet side of the installation box 1, and cool the tunnel as the underground ventilation system works.
