Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a cooling device and cooling system for cooling cast-in-place concrete structures. Background Technology

[0002] During the pouring and curing of high-strength concrete, a significant amount of heat of hydration is generated within the concrete. However, due to concrete's poor thermal conductivity, the central area of ​​the concrete heats up rapidly, while the surface of the concrete structure dissipates heat quickly and remains at a lower temperature. This temperature gradient can lead to a series of problems, such as cracking, deformation, and damage, and this is particularly problematic for larger structural members. For large concrete columns, a cooling pipe system is typically used to control the concrete temperature. Cooling water pumped from a water tank flows through the cooling pipes, absorbs the heat of hydration generated by the concrete, and then flows back to the water tank. The water tank dissipates heat through airflow or by adding ice.

[0003] In existing technologies, when cooling concrete structures, cooling pipes are typically made of galvanized steel pipes in a U-shape, with water entering at one end and exiting at the other. However, the U-shaped cooling pipes must be paired, one for inlet and one for outlet, which limits their flexible arrangement. For example, ideally, for a circular cross-section, the cooling pipes should be arranged symmetrically around the center, with one pipe at the center; U-shaped cooling pipes cannot meet this requirement. While using U-shaped pipes for cooling can achieve partial cooling of concrete structures, it is not suitable for cooling concrete structures of different diameters, and there is also the limitation of not being able to freely arrange the cooling pipes within the concrete structure, thus affecting the cooling effect inside the concrete structure. Utility Model Content

[0004] The main purpose of this utility model is to propose a cooling device and cooling system for cooling cast-in-place concrete structures. It aims to solve the technical problems in the prior art where U-shaped pipes are used as cooling pipes. Although they can achieve partial cooling of concrete structures, they cannot be adapted to cooling operations of concrete structures with different diameters. At the same time, the cooling pipes cannot be freely arranged inside the concrete structure, which affects the cooling effect inside the concrete structure.

[0005] To achieve the above objectives, this utility model proposes a cooling device for cooling cast-in-place concrete structures, comprising:

[0006] A cooling pipe is arranged along the extension direction of the concrete structure, and the two ends of the cooling pipe are a first blind end and an inlet and outlet, respectively. The first blind end extends to the end of the concrete structure, and the inlet and outlet extend out of the concrete structure. The inlet and outlet have an inlet and an outlet that are spaced apart from each other, and the inlet is connected to an external water pipe.

[0007] A cooling water circulation mechanism is detachably installed inside the cooling pipe, and the two ends of the cooling water circulation mechanism are a connection end and a water outlet end, respectively. The connection end is connected to the external water pipe, and the water outlet end extends from the water inlet end to the first blind end along the extension direction of the cooling pipe. The cooling water circulation mechanism enables the cooling water flowing into the cooling pipe to form a vortex and be discharged from the cooling pipe through the water outlet.

[0008] In one embodiment, the cooling water circulation mechanism includes:

[0009] A water supply pipe, wherein the two ends of the water supply pipe are the connection end and the outlet end, respectively, and the water supply pipe extends from the inlet and outlet towards the first blind end along the extension direction of the cooling pipe.

[0010] A water distribution assembly, wherein the water distribution assembly is installed at the water outlet end, and the water distribution assembly gradients water from the water outlet end toward the first blind end; and,

[0011] A water flow rate regulating component is rotatably mounted on the outer periphery of the water supply pipe, and the water flow rate regulating component can regulate the flow rate of cooling water flowing out from the water distribution component through the water supply pipe.

[0012] In one embodiment, the water separation component includes:

[0013] A connecting blade ring, one end of which is connected to the water outlet, and the other end of which is folded outward to form a first folded edge; and,

[0014] A first dispersing blade ring is connected to a first folded edge. A plurality of water-dividing holes are formed between the first dispersing blade ring and the folded edge, and the end of the first dispersing blade ring away from the first folded edge is folded outward to form a second folded edge arranged parallel to the first folded edge. A water-dividing channel is formed between the first folded edge and the second folded edge, which is connected to all the water-dividing holes. The second folded edge is sealed to form a second blind end.

[0015] In one embodiment, the water-dividing assembly further includes a second dispersing blade ring disposed between the connecting blade ring and the first dispersing blade ring. The end of the second dispersing blade ring near the first dispersing blade ring is folded outward to form a third folded edge. The water-dividing channel is formed between the first folded edge and the third folded edge, as well as between the third folded edge and the second folded edge.

[0016] In one embodiment, there are multiple second dispersion blade rings, and the multiple second dispersion blade rings are sequentially connected along the direction from the connecting blade ring to the first dispersion blade ring.

[0017] In one embodiment, the water flow velocity regulating component includes:

[0018] A sleeve, the sleeve being rotatably fitted onto the outer periphery of the water supply pipe; and,

[0019] Multiple blades are arranged at an angle outward along the direction from the water outlet to the water inlet / outlet. Cooling water can flow out between any two adjacent blades to drive the sleeve to rotate around the water supply pipe.

[0020] In one embodiment, there are multiple water flow rate regulating components, which are arranged to rotate sequentially along the extension direction of the water supply pipe.

[0021] In one embodiment, the number of cooling pipes is multiple, and the multiple cooling pipes are arranged in an equilateral polygon.

[0022] In one embodiment, the cooling pipe is connected to multiple reinforcing bars to form a reinforcing cage for the concrete structure.

[0023] Based on the same technical concept, in a second aspect, this utility model also proposes a cooling system that applies the cooling device for cooling cast-in-place concrete structures described in the first aspect.

[0024] The technical solution of this utility model involves setting up cooling pipes and a cooling water circulation mechanism. In use, the cooling pipes are installed within the concrete structure along its extension direction, with the blind end of the cooling pipe extending to the end of the concrete structure and the inlet and outlet extending out of the concrete structure. The cooling water circulation mechanism is installed inside the cooling pipes, allowing the utility model to supply cooling water to the cooling pipes. This enables the utility model to cool the interior of the concrete structure using the cooling pipes arranged along the extension direction of the concrete structure. Furthermore, arranging the cooling pipes along the extension direction of the concrete structure allows for free arrangement within the concrete structure, enabling cooling of different concrete structures and ensuring effective cooling.

[0036] Please see Figures 1 to 4 In one embodiment of this utility model, the cooling device for cooling a cast-in-place concrete structure 300 includes:

[0037] Cooling pipe 100 is arranged along the extension direction of concrete structure 300, and the two ends of cooling pipe 100 are a first blind end 110 and an inlet / outlet 122, respectively. The first blind end 110 extends to the end of concrete structure 300, and the inlet / outlet 122 extends out of concrete structure 300. The inlet / outlet 122 has an inlet 121 and an outlet 122 that are spaced apart from each other. The inlet 121 is connected to an external water pipe 10.

[0038] The cooling water circulation mechanism 200 is detachably installed inside the cooling pipe 100. The two ends of the cooling water circulation mechanism 200 are a connection end 210 and an outlet end 220, respectively. The connection end 210 is connected to the external water pipe 10, and the outlet end 220 extends from the inlet end to the first blind end 110 along the extension direction of the cooling pipe 100. The cooling water circulation mechanism 200 can make the cooling water flowing into the cooling pipe 100 form a vortex and be discharged from the cooling pipe 100 through the outlet 122.

[0039] It should be specifically and clearly stated that, in this embodiment, the example cooling pipe 100 can be a straight pipe or an S-shaped pipe, etc., with both ends located at both ends. In this embodiment, the example cooling pipe 100 is preferably a straight pipe. In this embodiment, the example external water pipe 10 is also connected to the external water tank 30 through an external water pump 20, so that in actual use, the present invention can utilize the cooperation of the external water pump 20 and the external water tank 30 to pump the cooling water stored in the external water tank 30 into the cooling pipe 100 to cool the concrete structure.

[0040] In this embodiment, by setting up a cooling pipe 100 and a cooling water circulation mechanism 200, during use, the cooling pipe 100 is installed inside the concrete structure 300 along its extension direction, with the blind end of the cooling pipe 100 extending to the end of the concrete structure 300. The inlet / outlet 122 extends out of the concrete structure 300. The cooling water circulation mechanism 200 is installed inside the cooling pipe 100, allowing the present invention to provide cooling water to the cooling pipe 100. This enables the present invention to cool the interior of the concrete structure 300 using the cooling pipe 100 arranged along the extension direction of the concrete structure 300. Furthermore, arranging the cooling pipe 100 along the extension direction of the concrete structure 300 allows for free arrangement within the concrete structure 300, enabling cooling of different concrete structures and ensuring effective cooling.

[0041] In some specific embodiments, the cooling water circulation mechanism 200 includes:

[0042] Water supply pipe 230, with a connection end 210 and an outlet end 220 at its two ends, extends from the inlet / outlet 122 toward the first blind end 110 along the extension direction of cooling pipe 100.

[0043] Water distribution component 240 is installed at the outlet end 220, and the water distribution component 240 gradient-distributes water from the outlet end 220 toward the first blind end 110; and,

[0044] The water flow rate regulating component 250 is rotatably mounted on the outer periphery of the water supply pipe 230. The water flow rate regulating component 250 can regulate the flow rate of the cooling water that flows out from the water distribution component 240 through the water supply pipe 230.

[0045] In this embodiment, by setting up a water supply pipe 230, a water distribution component 240, and a water flow rate adjustment component 250, during use, the connection end 210 of the water supply pipe 230 is connected to the inlet 121 of the cooling pipe 100, and the water distribution component 240 is installed at the outlet end 220 of the water supply pipe 230. The water flow rate adjustment component 250 is rotatably installed on the outer periphery of the water supply pipe 230. This allows the water distribution component 240 to disperse the cooling water supplied through the water supply pipe 230, ensuring that different locations within the cooling pipe 100 are exposed to cooling water of varying temperatures, thus improving cooling efficiency. Simultaneously, the water flow rate adjustment component 250 can be used to adjust the water flow rate within the cooling pipe 100, thereby enabling the adjustment of the cooling water flow rate after cooling the concrete structure 300, and ultimately changing the cooling efficiency.

[0046] In some specific embodiments, the water separation component 240 includes:

[0047] A connecting blade ring 241 is provided, one end of which is connected to the outlet end 220, and the other end is folded outward to form a first folded edge 242; and,

[0048] A first dispersing blade ring 243 is connected to a first folded edge 242. A plurality of water-dividing holes are formed between the first dispersing blade ring 243 and the folded edge, and the end of the first dispersing blade ring 243 away from the first folded edge 242 is folded outward to form a second folded edge 244 arranged parallel to the first folded edge 242. A water-dividing channel 247 is formed between the first folded edge 242 and the second folded edge 244, which is connected to all the water-dividing holes. The second folded edge 244 is sealed to form a second blind end.

[0049] In this embodiment, by setting the connecting blade ring 241 and the first dispersing blade ring 243, the present invention can achieve the function of diverting cooling water by using the connecting blade ring 241 and the dispersing blade ring, so that different positions of the cooling pipe 100 can come into contact with cooling water at a lower temperature, thereby improving the cooling efficiency.

[0050] Of course, in some preferred embodiments, the water distribution assembly 240 further includes a second dispersing blade ring 245 that is connected between the connecting blade ring 241 and the first dispersing blade ring 243. The end of the second dispersing blade ring 245 near the first dispersing blade ring 243 is folded outward to form a third folded edge 246. Water distribution channels 247 are formed between the first folded edge 242 and the third folded edge 246, and between the third folded edge 246 and the second folded edge 244.

[0051] There are multiple second dispersion blade rings 245, and the multiple second dispersion blade rings 245 are sequentially connected along the direction connecting blade ring 241 to first dispersion blade ring 243.

[0052] In this embodiment, by setting the number of second dispersing blades to multiple, and making the multiple second dispersing blades sequentially connected along the direction from the connecting blade to the first dispersing blade, the present invention can provide more water distribution channels 247 in the cooling pipe 100 during specific implementation, so as to realize the function of cooling more locations inside the concrete structure 300.

[0053] It should be specifically and clearly stated that, in this embodiment, the first dispersing blade, the connecting blade, and the second dispersing blade can be continuously arranged, or they can be connected by extending pipe sections between two adjacent second dispersing blades, between the first dispersing blade and an adjacent second dispersing blade, and between the second dispersing blade and the connecting blade. It should also be noted that, in this embodiment, by sealing one end corresponding to the first folded edge 242 of the first dispersing blade, the cooling water can be prevented from directly rushing out from the opening of the first folded edge 242 during use, thus improving the dispersion effect of the cooling water.

[0054] In some specific embodiments, the water flow velocity regulating component 250 includes:

[0055] Sleeve 251, sleeve 251 is rotatably fitted onto the outer periphery of water supply pipe 230; and,

[0056] Multiple blades 252 are inclined outward along the direction from the water outlet 220 to the water inlet / outlet 122. Cooling water can flow out from between any two adjacent blades 252 to drive the sleeve 251 to rotate around the water supply pipe 230.

[0057] In this embodiment, by setting the sleeve 251 and multiple blades 252, the present invention can change the flow rate of water after cooling the concrete structure 300 during use, thereby enabling the cooling water to stay in the cooling pipe 100 for a longer time, so as to improve the cooling effect on the concrete structure 300.

[0058] Of course, when the hydration heat temperature inside the concrete structure 300 is high and it is necessary to speed up heat dissipation, the flow rate can also be increased by increasing the supply flow rate of cooling water or by changing the size of the drain pipe of the outlet 122.

[0059] In one embodiment, there are multiple water flow rate regulating components 250, which are arranged to rotate sequentially along the extension direction of the water supply pipe 230.

[0060] In this embodiment, by setting multiple water flow rate adjustment components 250, the water flow rate in the cooling pipe 100 can be further reduced during the specific implementation of this invention, thereby improving the cooling effect on the concrete structure 300.

[0061] It should be specifically and clearly stated that, in this embodiment, among the plurality of water flow rate regulating components 250 in the example, the rotation directions of any two adjacent water flow rate regulating components 250 are opposite. This arrangement allows the present invention to further reduce the water flow rate within the cooling pipe 100, thereby achieving the function of fully cooling the concrete structure 300.

[0062] In one embodiment, there are multiple cooling pipes 100 arranged in an equilateral polygon.

[0063] In this embodiment, the number of cooling pipes 100 is set to multiple, so that more cooling pipes 100 can be arranged in the concrete structure 300 during use, thereby improving the cooling effect on the concrete structure 300.

[0064] In one embodiment, the cooling pipe 100 is connected to a plurality of steel bars to form a steel cage for the concrete structure 300.

[0065] In this embodiment, the cooling pipe 100 is connected to the reinforcing bar to form a reinforcing cage, which enables the cooling pipe 100 to become part of the concrete structure 300 after completing the cooling operation of the concrete structure 300, thus improving the applicability of the cooling pipe 100.

[0066] Based on the same technical concept, in a second aspect, this utility model also proposes a cooling system that applies the cooling device of the first aspect for cooling cast-in-place concrete structures 300.

[0067] The cooling system provided in this application embodiment employs the cooling device for cooling the cast-in-place concrete structure 300 described in the above embodiments. This solves the technical problems of using U-shaped pipes as cooling pipes 100, which, while achieving partial cooling of the concrete structure 300, cannot be adapted to cooling operations on concrete structures 300 of different diameters. Furthermore, it addresses the issue of the inability to freely arrange the cooling pipes 100 within the concrete structure 300, thus affecting the internal cooling effect. Compared to the prior art, the beneficial effects of the cooling system provided in this application embodiment are the same as those of the cooling device for cooling the cast-in-place concrete structure 300 provided in the above embodiments, and other technical features of the cooling system are the same as those disclosed in the above embodiments, and will not be repeated here.
