Description

Technical Field

[0001] This utility model relates to the field of large-volume concrete construction technology, and in particular to a temperature crack control system for large-volume concrete. Background Technology

[0002] Mass concrete is widely used in municipal engineering, bridges, and water conservancy projects. Due to its large volume, the heat generated during cement hydration is difficult to dissipate naturally. The temperature difference between the inside and outside of the concrete can cause shrinkage and cracks during cooling, affecting its performance. Current solutions involve installing water circulation pipes inside the concrete to cool it. However, when these pipes are not in use, sediment and other impurities can enter and clog the inlets and outlets, hindering their operation. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a temperature crack control system for large-volume concrete. This solves the technical problem in the existing large-volume concrete temperature crack control system where, after the water circulation pipe is not in use, impurities such as mud and sand enter the inlet and outlet of the water circulation pipe at both ends, blocking the inlet and outlet and affecting the use of the water circulation pipe.

[0004] To achieve the above technical objectives, the present invention provides a temperature crack control system for large-volume concrete, including a water circulation pipe installed inside the concrete. The water circulation pipe has an inlet and a outlet at both ends. The control system also includes an anti-clogging device, which includes a base. The front two ends of the base are provided with grooves. The inlet and outlet are respectively located inside the two grooves. The openings of the two grooves are provided with sealing plates. The base has a through hole connecting the two grooves. The two sealing plates are slidably disposed inside the two through holes, and their opposite ends are connected by an elastic element.

[0005] Furthermore, the front side of the base is provided with a rotating groove that communicates with the through hole. A rotating disk is provided inside the rotating groove. The rotating disk is provided with two sliding holes. Both closed plates are provided with sliders. The two sliders are respectively slidably disposed inside the two sliding holes.

[0006] Furthermore, the inner wall of the rotating groove is provided with an annular limiting groove, and the side wall of the rotating disk is provided with an annular limiting ring that is rotatably located inside the annular slot.

[0007] Furthermore, a handle is installed on the rotating disc.

[0008] Furthermore, the handle includes a first rod, a fixed sleeve is provided on the front side of the rotating disk, the first rod is movably disposed inside the fixed sleeve, a stop block for blocking the first rod is installed on the front side of the seat, and a second rod is vertically installed at one end of the first rod.

[0009] Furthermore, the first rod body is provided with a slot that cooperates with the stop block.

[0010] Furthermore, multiple heat dissipation fins are evenly spaced inside the concrete, and water circulation pipes are arranged in a wave-like pattern around the multiple heat dissipation fins.

[0011] The beneficial effects of this utility model include:

[0012] 1. When using the water circulation pipe, push the two sealing plates to retract them into the through hole, opening the openings on the two grooves. This allows the water supply equipment to be connected to the inlet and outlet. After the water circulation pipe is used, the two sealing plates can be moved by the elastic element to close the openings on the two grooves. This prevents impurities such as mud and sand from entering the inlet and outlet at both ends of the water circulation pipe, thus blocking them and affecting the use of the water circulation pipe.

[0013] 2. By rotating the rotating disk, the two sliders can slide inside the two sliding holes, thereby pushing the two sealing plates to move and retract them into the through holes, so as to open the openings on the two grooves. The operation is convenient. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] This utility model provides a temperature crack control system for large-volume concrete, such as... Figure 1-4 As shown, the system includes a water circulation pipe 2 installed inside concrete 1. The water circulation pipe 2 has an inlet 21 and an outlet 22 at each end. The control system also includes an anti-clogging device 3, which includes a base 31. Both ends of the front side of the base 31 have grooves 311. The inlet 21 and outlet 22 are respectively located inside the two grooves 311. Each opening of the two grooves 311 has a sealing plate 33. The base 31 has a through hole 312 connecting the two grooves 311. The two sealing plates 33 are slidably disposed inside the two through holes 312, and their opposite ends are connected by an elastic element 32. Using either a spring or a metal spring, when the water circulation pipe 2 is in use, pushing the two sealing plates 33 moves them back into the through hole 312, opening the openings on the two grooves 311, thus connecting the water supply equipment to the inlet 21 and the outlet 22. When the water circulation pipe is no longer in use, the elastic element 32 can push the two sealing plates 33 to close the openings on the two grooves 311, thereby preventing impurities such as mud and sand from entering the inlet 21 and outlet 22 at both ends of the water circulation pipe, clogging the inlet 21 and outlet 22, and affecting the use of the water circulation pipe 2.

[0021] It should be noted that mounting holes are provided at both ends of the back of the base 31, and the two ends of the water circulation pipe 2 are fixed inside the two mounting holes respectively, so that the water inlet 21 and the drain outlet 22 are respectively located inside the two grooves 311.

[0022] In this embodiment, multiple heat dissipation fins 4 are provided at equal intervals inside the concrete 1, and the water circulation pipe 2 is arranged in a wave shape around the multiple heat dissipation fins 4. The cooling effect on the concrete 1 can be improved through the heat dissipation fins 4.

[0023] In this embodiment, the front side of the base 31 is provided with a rotating groove 313 communicating with the through hole 312. A rotating disk 34 is rotatably provided inside the rotating groove 313. The rotating disk 34 is provided with two sliding holes 341. Both of the two sealing plates 33 are provided with sliders 331. The two sliders 331 are slidably disposed inside the two sliding holes 341 respectively. By rotating the rotating disk 34, the two sliders 331 can be driven to slide inside the two sliding holes 341, thereby pushing the two sealing plates 33 to move and retract the two sealing plates 33 into the through hole 312, so as to open the openings on the two grooves 311, which is convenient to operate.

[0024] It should be noted that the inner wall of the rotating groove 313 is provided with an annular limiting groove 314, and the side wall of the rotating disk 34 is provided with an annular limiting ring 342 that is rotatably disposed inside the annular groove 314. The rotating disk 34 can be rotatably installed inside the rotating groove 313 by the cooperation of the annular limiting groove 314 and the annular limiting ring 342.

[0025] In this embodiment, a handle 35 is installed on the rotating disk 34. More specifically, the handle 35 includes a first rod 351. A fixing sleeve 343 is provided on the front side of the rotating disk 34. The first rod 34 is movably disposed inside the fixing sleeve 343. A stop block 315 for blocking the first rod 34 is installed on the front side of the seat 31. A second rod 352 is vertically installed at one end of the first rod 351. By providing a handle 35 on the rotating disk 34, the rotating disk 34 can be easily rotated. At the same time, when the two sealing plates 33 move, the openings on the two grooves 311 are opened. When the opening is fully open, the movable first rod 34 can be blocked by the stop block 315 to prevent the elastic member 32 from pushing. The stop block 315 automatically closes the opening on the groove 311, so that the water supply equipment can be easily connected to the water inlet 21 and the drain outlet 22. At the same time, the first rod 351 is provided with a slot 3511 that cooperates with the stop block 315. When the stop block 315 blocks the first rod 351, the stop block 35 can be inserted into the slot 3511 to prevent the position of the first rod 351 from moving.

[0026] It should be noted that when the handle 35 is not in use, the first rod 351 can be pulled out from inside the fixed sleeve 343 to prevent non-staff members from opening the opening on the groove 311 through the handle 35.

[0027] In terms of specific principle, when cooling concrete 1, turning handle 33 causes rotating disk 34 to rotate. Rotating disk 34 causes two sliders 331 to slide inside two sliding holes 341, thereby pushing two sealing plates 33 to move and retract into the through hole 312, opening the openings on the two grooves 311. This allows the water supply equipment to be connected to the inlet 21 and outlet 22. After the water supply equipment is connected to the inlet 21 and outlet 22, it supplies water to the water circulation pipe 2 to cool concrete 1. After the concrete 1 has cooled down, the water supply equipment is removed from the inlet 21 and outlet 22. The elastic element 32 can push the two sealing plates 33 to move and close the openings on the two grooves 311, thus preventing impurities such as mud and sand from entering the inlet 21 and outlet 22 at both ends of the water circulation pipe 2, blocking the inlet 21 and outlet 22, and affecting the use of the water circulation pipe 2.

[0028] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
