Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a quick connection device for large-volume concrete cooling water pipes. Background Technology

[0002] During the pouring of large-volume concrete, cooling water pipes are pre-embedded inside to reduce the heat of hydration inside the large-volume concrete after pouring.

[0003] Pre-embedded cooling water pipes are relatively long and are generally composed of multiple pipes spliced ​​together. Currently, adjacent cooling water pipes are usually connected by welding or binding. Welding is costly and inefficient, and the quality of the cooling water pipe structure is easily affected by welding techniques; binding is inefficient, produces poor quality, and the joints are prone to loosening and leakage. Utility Model Content

[0004] Therefore, it is necessary to provide a rapid connection device for large-volume concrete cooling water pipes to accelerate and standardize the connection of cooling water pipes, so as to overcome the current technical difficulties in assembling cooling water pipe structures.

[0005] A quick-connection device for large-volume concrete cooling water pipes includes:

[0006] A transparent main tube with graduation lines on the middle of its outer circumference;

[0007] A connecting sub-tube is provided with gradually expanding sealing flanges at intervals on its outer periphery. The end of the connecting sub-tube is inserted into the transparent main tube and connected to the transparent main tube by a fixing device.

[0008] A leakage indicator ring is located at the end of the outermost sealing flange and is used to detect whether cooling water is flowing out of the transparent main pipe.

[0009] As a preferred embodiment of the rapid connection device for large-volume concrete cooling water pipes in this utility model, the inner diameter of the transparent mother pipe is equal to the maximum outer diameter of the connecting daughter pipe.

[0010] As a preferred embodiment of the quick connection device for large-volume concrete cooling water pipes in this utility model, the inner diameter of the connecting sub-pipe is not greater than the outer diameter of the cooling water pipe.

[0011] As a preferred embodiment of the quick connection device for large-volume concrete cooling water pipes in this utility model, the fixing device is sleeved on the outer periphery of the transparent main pipe and between adjacent sealing flanges, and is used to connect the transparent main pipe and the connecting daughter pipe.

[0012] As a preferred embodiment of the quick connection device for large-volume concrete cooling water pipes in this utility model, the leakage indicator ring is attached to the outermost sealing flange away from the adjacent sealing flange side, and it changes color when exposed to water and moisture.

[0013] As a preferred embodiment of the quick connection device for large-volume concrete cooling water pipes in this utility model, the quick connection device for cooling water pipes also includes a heating device for drying the leakage indicator ring that changes color when wet.

[0014] The beneficial effects of this utility model are:

[0015] This invention replaces the original welding connection method with a mechanical connection method. The connecting sub-tube is sleeved on the outer periphery of the transparent main tube, and the connecting sub-tube is inserted into the transparent main tube. The cooling water pipe is fixed in the transparent main tube by a fixing device. The connection method is more convenient and faster. At the same time, the modular connection method greatly improves the connection quality of the cooling water pipe.

[0016] After the cooling water pipe structure of this utility model is assembled, a water test can be performed. If the connection is not firm, the leakage indicator ring can detect it in time, and then reinforcement can be carried out to avoid leakage of the cooling water pipe structure during use, which would affect the quality of the concrete.

[0031] Example 1

[0032] This embodiment provides a quick connection device for large-volume concrete cooling water pipes, such as... Figure 1 As shown, it includes a transparent main tube 1000, a connecting sub-tube 2000, and a fixing device 3000.

[0033] The connecting sub-pipe 2000 is sleeved on the interconnecting side of the cooling water pipes 5000. The cooling water pipes 5000 are inserted from the end of the transparent main pipe 1000 to its center through the connecting sub-pipe 2000 and abut against the adjacent cooling water pipes 5000. The fixing device 3000 is used to fix the transparent main pipe 1000, the connecting sub-pipe 2000 and the cooling water pipes 5000.

[0034] The transparent main tube 1000 is a hollow structure with a uniform cross-section, made of transparent elastic material. It has a scale line in the middle of its outer periphery. The cooling water pipe 5000 inserted into the transparent main tube 1000 abuts at the scale line to facilitate observation of the connection status of the cooling water pipe 5000 and its position in the transparent main tube 1000.

[0035] The outer periphery of the connecting sub-tube 2000 is provided with multiple sealing flanges 2100 spaced apart. The diameter of the multiple sealing flanges 2100 gradually increases from one end to the other, and the outer diameter of the sealing flange 2100 with the largest diameter is equal to the inner diameter of the transparent main tube 1000. The inner diameter of the connecting sub-tube 2000 is not less than the outer diameter of the cooling water pipe 5000, so as to ensure a more secure connection between the connecting sub-tube 2000 and the cooling water pipe 5000 and prevent cooling water from flowing out between the connecting sub-tube 2000 and the cooling water pipe 5000. At the same time, it also allows both to be inserted simultaneously into the transparent main tube 1000.

[0036] In this embodiment, a connecting platform is provided at the connection between the sealing flange 2100 and the transparent mother tube 1000, which increases the contact surface and achieves a better sealing effect.

[0037] When the connecting sub-pipe 2000 is connected to the cooling water pipe 5000, the end with the smallest outer diameter is flush with the abutting end of the cooling water pipe 5000. The gradually expanding sealing flange 2100 structure helps the cooling water pipe 5000 to be inserted into the transparent mother pipe 1000 more quickly and conveniently.

[0038] The fixing device 3000 is sleeved on the outer periphery of the transparent main tube 1000 and between adjacent sealing flanges 2100. It is used to connect the transparent main tube 1000 and the connecting daughter tube 2000, fix the cooling water pipe 5000 inside the transparent main tube 1000, and also play a sealing role to prevent cooling water from flowing out of the transparent main tube 1000.

[0039] Example 2

[0040] The difference between this embodiment and embodiment 1 is that it also includes a water leakage indicator ring 4000, which is located at the end of the outermost sealing flange 2100 and is used to detect whether cooling water flows out of the transparent main pipe 1000. The water leakage indicator ring 4000 is attached to the side of the outermost sealing flange 2100 away from the adjacent sealing flange 2100. It changes color when it gets wet and returns to its original color when it dries.

[0041] After the cooling water pipe 5000 structure is assembled, a water test can be conducted. If the connection is not secure, cooling water will flow out from the transparent main pipe 1000. Construction personnel can detect this in time through the leakage indicator ring 4000 and then reinforce it to prevent leakage of the cooling water pipe 5000 structure during use, which would affect the quality of the concrete.

[0042] It also includes a heating device for drying the leak indicator ring 4000, which becomes wet and discolored, so that a water test can be performed again after the connection is tightened.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
