Description

Technical Field

[0001] This utility model relates to the field of concrete cooling technology, and in particular to a zoned cooling device for large-volume concrete construction. Background Technology

[0002] Large-volume concrete structures (thickness ≥ 1m) are widely used in projects such as water conservancy projects, nuclear power plant foundations, and raft slabs for high-rise buildings. Due to the large amount of heat released during cement hydration and the low thermal conductivity of concrete (typically 1.28-3.6 W / (m·K)), the internal temperature of the structure rises rapidly (up to 60-80℃), while the surface cools quickly due to ambient temperature, creating a significant internal-external temperature difference (specifications require ≤25℃). When the temperature stress generated by this difference exceeds the tensile strength of the concrete, harmful temperature cracks will occur, severely affecting the structure's durability and load-bearing capacity. Traditional temperature control measures often involve pre-embedded cooling water pipes for circulating cooling.

[0003] Existing zoned cooling devices are mostly fixed in shape and size, making them inconvenient to adjust flexibly. They are difficult to adapt to different concrete structures, requiring remanufacturing or modification. Furthermore, the difficulty in flexibly adjusting the spray zones can easily lead to uneven spraying. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a zoned cooling device for large-volume concrete construction, including a main water supply pipe 1, the surface of which is provided with a plurality of water supply connectors 11; a connector 2, which is connected to the main water supply pipe 1 through the water supply connectors 11, and the other end of the connector 2 is connected to a spraying component 3; the spraying component 3 includes a spray pipe 31 and a nozzle 32, the spray pipe 31 is connected to the connector 2, and the nozzle 32 faces the concrete surface.

[0029] Specifically, the main water supply pipe 1 is used to supply water to the spray pipes 31 of each zone. The main water supply pipe 1 is arranged along the concrete surface. Water supply connectors 11 are evenly distributed on both sides of the main water supply pipe 1 for installing corresponding spray components 3. By installing the spray components 3, spraying can be carried out on the corresponding areas, which can effectively and evenly spray and cool the large volume of concrete. The connector 2 is used to connect the spray components 3 to the main water supply pipe 1, and also serves to seal the water supply connectors 11 when not connected.

[0030] Reference Figures 1-3 Furthermore, the connector 2 includes a closed head 21 disposed on the water supply connector 11. The closed head 21 is provided with a mounting plate 22. An elastic element 23 is mounted on the mounting plate 22. A ball head 24 is mounted on the top of the elastic element 23. The mounting plate 22 is fixedly connected to the inner wall of the closed head 21. The mounting plate 22 has a through hole in the center for water to flow through. The elastic element 23 can be a spring or other structure that can perform the same function. The ball head 24 is connected to the mounting plate 22 through the elastic element 23.

[0031] Furthermore, the top of the closed head 21 is provided with a constriction, and the ball head 24 is adapted to the closed head 21. The surface of the mounting plate 22 is provided with several water passage grooves. In the default state, the ball head 24 is pushed out by the spring, and the surface of the ball head 24 is in complete contact with the constriction part of the closed head 21, thereby blocking the closed head 21. At this time, the water supply connector 11 is closed and no water is supplied to the outside. By setting an additional water supply groove on the mounting plate 22, the water delivery efficiency can be improved.

[0032] Furthermore, the connector 2 also includes a sleeve 25 fitted onto the closed head 21. Several connecting rods 26 are fixedly connected to the inner wall of the sleeve 25. A push rod 27 is fixedly connected to the connecting rod 26. The push rod 27 is coaxially arranged with the sleeve 25. The sleeve 25 and the closed head 21 can be connected by various methods such as threaded connection and flange connection. The connection between the sleeve 25 and the closed head 21 is sealed. The push rod 27 is located on the axis of the sleeve 25. When the sleeve 25 is installed, the push rod 27 can direct the ball head 24 toward the mounting plate 22.

[0033] Furthermore, the nozzle of the spray pipe 31 is also equipped with a sealing head 21, a mounting plate 22, an elastic element 23, and a ball head 24. The two ends of the push rod 27 simultaneously press against the ball head 24, so that the spray pipe 31 can also achieve the effect of being closed and opened by the push rod 27.

[0034] Operating procedure: When using, first install the main water supply pipe 1 next to the large volume concrete, then divide the large volume concrete into sections. At this time, each water supply connector 11 corresponds to one section. Then, install the spraying components 3 in the areas that need to be sprayed for cooling. First, install the sleeve 25 of the connector 2 on the closed head 21 of the water supply connector 11, tighten and fix it, then open the water supply connector 11 with the top rod 27. Then, install the spray pipe 31 on the corresponding sleeve 25. At this time, the main water supply pipe 1 is connected to the spray pipe 31. Install each spraying component 3 in sequence. After the installation is completed, start supplying water to the main water supply pipe 1, so that the corresponding spraying component 3 can start spraying and spray the surface of the large volume concrete in sections.

[0035] Areas that do not require spraying do not need to have sprayer 3 installed, as water will not be supplied to the sprayer because connector 2 closes the water supply connector 11.

[0036] Example 2

[0037] Reference Figures 1-4 This is the second embodiment of the present utility model. Unlike the previous embodiment, it also includes a water collection component 4. The water collection component 4 includes an installation rod 41 installed on the outer wall of the spray pipe 31. A collection box 42 is installed at the bottom end of the installation rod 41. A water inlet 44 is provided on the upper surface of the collection box 42.

[0038] Specifically, the mounting rod 41 is positioned below the spray area, thereby using the collection box 42 to collect excess water after spraying.

[0039] Furthermore, the mounting rod 41 is oriented towards the direction of gravity, the water inlet 44 is oriented towards the nozzle 32, and the collection box 42 is used to collect the sprayed water.

[0040] The rest of the structure is the same as in Example 1.

[0041] Operation process: The collection box 42 can be pre-installed on the spray pipe 31. The side of the collection box 42 protrudes from the nozzle 32, so that when the nozzle 32 sprays, the side wall of the collection box 42 can stick to the concrete surface. At this time, when the nozzle 32 sprays, the excess water flows down the concrete surface and flows directly into the collection box 42 from the inlet 44 for collection, reducing the water flowing to the next section and preventing water from accumulating at the bottom of the concrete.

[0042] Example 3

[0043] Reference Figures 1-4 This is the third embodiment of the present invention. Unlike the previous embodiments, a shovel 43 is provided on one side of the inlet 44. The shovel 43 is in close contact with the concrete surface and is used to guide the water flow into the collection box 42. The shovel 43 can collect the water flow better.

[0044] Specifically, the upper surface of the collection box 42 is provided with several movable tracks 45, and the bottom end of the mounting rod 41 is provided with a connecting notch 46. The movable tracks 45 are adapted to the connecting notch 46. By setting the movable tracks 45, the collection box 42 can be moved, so that the collection box 42 can be closer to or further away from the concrete. Thus, the size of the collection box 42 no longer needs to protrude from the spraying component 3, and the distance between the spraying component 3 and the concrete surface can be flexibly adjusted. Only the movable tracks 45 need to be adjusted.

[0045] Furthermore, the moving direction of the movable track 45 is the same as the water spraying direction of the nozzle 32. The movable track 45 is slidably engaged with the connecting notch 46. By opening a notch on the mounting rod 41, the collection box 42 is changed to be movably connected to the mounting rod 41 via the movable track 45. At this time, the collection box 42 can be made into a detachable design. The collection box 42 can also be equipped with a drain outlet. While collecting water, excess water can be discharged through the drain outlet and pipe for reuse.

[0046] The rest of the structure is the same as in Example 2.

[0047] Operation process: Before installing the spray component 3, the collection box 42 is moved away from the concrete via the movable track 45. This avoids the installation area and facilitates installation. After installing the spray component 3, the collection box 42 is moved closer to the concrete surface via the movable track 45 until the collection box 42 is pressed against the concrete surface.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
