Description

Technical Field

[0001] This utility model relates to the field of concrete curing equipment technology, and in particular to a large-volume concrete curing spray device. Background Technology

[0002] Mass concrete, due to its large volume, extensive exposed surface during construction, and significant susceptibility to ambient temperature changes, is highly susceptible to cracking caused by the heat generated during cement hydration after pouring. This heat can easily create a large temperature difference between the concrete's interior and surface, threatening structural quality. Therefore, temperature and humidity control during the curing stage is crucial. Spraying devices, by continuously spraying water to moisturize the concrete while simultaneously cooling it, effectively control the internal temperature of the concrete, enhance its crack resistance, and ensure stable quality during curing. Consequently, they are widely used in the curing of mass concrete.

[0003] However, current mainstream traditional water spraying devices, such as fixed spray guns and ordinary straight pipe nozzles, are limited by their structural design, resulting in a relatively fixed coverage area. This makes it difficult to adapt to the "multi-dimensional and differentiated" actual needs of large-volume concrete curing processes. Specifically, the problems manifest in the following two aspects: First, the core limitation of traditional water spraying devices lies in their fixed and unadjustable spray coverage area, resulting in extremely poor flexibility. Because different areas of large-volume concrete require significantly different curing conditions, these devices cannot flexibly adjust the spray range according to actual needs, leading to a severe lack of adaptability and making it difficult to achieve precise curing across the entire area.

[0004] Secondly, the labor costs and intensity of curing operations are very high, and the problem of "missed areas" is also prone to occur. If a traditional sprinkler head is fixed in a certain position, it can only cover a small, localized area. When dealing with a large area of ​​concrete surface, it is necessary to frequently move the water supply pipeline manually or adjust the position of the support to expand the curing area. This not only greatly increases the labor costs and intensity of manual operation, but also causes "missed areas" due to the intervals between manual movements. The curing of large-volume concrete has very high requirements for "continuous and uniform moisture retention." Missed areas will have insufficient moisture, leading to incomplete cement hydration reaction, which in turn reduces the strength of the concrete and may even cause drying shrinkage cracks. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a large-volume concrete curing spray device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A large-volume concrete curing spraying device includes a water supply pipe connected to a sprinkler, and further includes: a supporting water pipe fixedly connected to both ends of the water supply pipe and symmetrically arranged thereon, with a connecting water pipe slidably inserted into the end of the supporting water pipe away from the spray pipe, and a telescopic water pipe slidably inserted into the end of the connecting water pipe away from the supporting water pipe; a connecting mechanism disposed on the supporting water pipe, the connecting water pipe and the telescopic water pipe; and nozzles installed on the outer walls of the spray pipe, the supporting water pipe, the connecting water pipe and the telescopic water pipe respectively.

[0007] As a further improvement of this utility model, the connecting mechanism includes a first external thread provided at the end of the connecting water pipe near the nozzle, the first external thread being spirally sleeved with the end of the supporting water pipe away from the spray pipe, and a second external thread provided at the end of the telescopic water pipe near the nozzle, the second external thread being spirally sleeved with the end of the connecting water pipe away from the supporting water pipe.

[0008] As a further improvement of this utility model, one end of the connecting water pipe inserted into the supporting water pipe is fixedly connected to a first retaining ring, and one end of the supporting water pipe is provided with a first rubber ring gasket that is tightly connected to the first retaining ring.

[0009] As a further improvement of this utility model, a second retaining ring is fixedly connected to one end of the telescopic water pipe inserted into the connecting water pipe, and a second rubber ring gasket that is tightly connected to the second retaining ring is provided inside one end of the connecting water pipe.

[0010] As a further improvement of this utility model, a side nozzle is fixedly connected to the end of the telescopic water pipe away from the connecting water pipe, and a valve is also provided at the end of the telescopic water pipe near the side nozzle.

[0011] As a further improvement of this utility model, the pair of supporting water pipes, connecting water pipes, telescopic water pipes, side nozzles and valves are all symmetrically arranged with the water spray pipe as the center.

[0013] This utility model utilizes the cooperation of structures such as a water supply pipe, a spray pipe, a supporting water pipe, a connecting water pipe, a telescopic water pipe, a side nozzle, a valve, and a first rubber ring gasket and a second rubber ring gasket.

At the same time, the first retaining ring and the first rubber ring gasket are tightly connected to achieve a fixed seal. Then, rotate the telescopic water pipe in the same way, and spirally engage with the connecting water pipe via the second external thread. The second retaining ring and the second rubber ring gasket abut against the extension device and ensure a seal. After adjusting the length, open the valve. Water flows through each pipe in sequence. Part of it is sprayed onto the main surface of the concrete through the nozzles on the outer wall of the spray pipe, support pipe, connecting pipe, and telescopic pipe. The other part is sprayed through the side nozzles to cover the side or edge areas. If the range needs to be adjusted, close the valve and reverse the connecting pipe or telescopic pipe to shorten the length of the device. After adjustment, reopen the valve to continue curing. The entire process does not require frequent movement of pipes or supports, reducing labor costs and labor intensity, while avoiding missed curing and meeting the need for continuous and uniform moisture retention for large-volume concrete.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0016] like Figures 1 to 3As shown, this utility model proposes a large-volume concrete curing spraying device, including a water supply pipe 1 connected to a sprinkler. The water supply pipe 1 is connected to the external sprinkler and serves as the main channel for water supply, introducing water from the sprinkler into the device to supply water to subsequent pipes and nozzles. The sprinkler is an external device that provides water to the large-volume concrete curing device. Its core function is to be directly connected to the water supply pipe 1 of the device, transporting water into the water supply pipe 1, and then distributing the water through the water supply pipe 1 to the internal pipelines of the device, such as the spray pipe 2, support pipe 3, connecting pipe 4, and telescopic pipe 5. Finally, the water is sprayed out through the nozzles 2345 and side nozzles 6, providing continuous moisture for the curing of large-volume concrete and meeting the requirement of "continuous and uniform moisturizing" during the curing process. It is an important water supply component for the device to achieve concrete spraying curing. The water supply pipe 1 is fixedly connected to symmetrically arranged support water pipes 3 at both ends. Corresponding nozzles 2345 are installed on the outer wall of the support water pipes 3, serving both to support and extend the pipeline, and to spray water to cure the concrete. A first rubber ring gasket 31 is also provided inside for sealing with the connecting water pipe 4. The end of the support water pipe 3 furthest from the spray pipe 2 is slidably connected to the connecting water pipe 4. Corresponding nozzles 2345 are installed on the outer wall of the connecting water pipe 4, serving to connect the support water pipe 3 to the telescopic water pipe 5 and extend the pipeline. Simultaneously, it sprays water to cure the concrete through its own nozzles 2345. One end of the connecting water pipe 4 has a first external thread 41, and the other end has a second rubber ring gasket 43 inside, used for spiral connection with the support water pipe 3 and sealing with the telescopic water pipe 5, respectively.

[0017] Among them, such as Figures 1 to 3 As shown, a telescopic water pipe 5 is slidably inserted into the end of the connecting water pipe 4 away from the supporting water pipe 3. A corresponding nozzle 2345 is installed on the outer wall of the telescopic water pipe 5, further extending the pipeline. The nozzle 2345 sprays water to cure the concrete and simultaneously supplies water to the side nozzles 6. The end of the nozzle 2345 near the nozzle 2345 has a second external thread 51, and the end inserted into the connecting water pipe 4 has a second retaining ring 52, used for spiral connection and sealing with the connecting water pipe 4, respectively. The nozzles 2345, installed on the outer walls of the water pipe 2, supporting water pipe 3, connecting water pipe 4, and telescopic water pipe 5, receive water from each pipe and spray it onto the concrete surface, providing continuous moisture to the main areas of the concrete, achieving moisture retention and curing, assisting in controlling the concrete temperature, and improving its crack resistance.

[0018] Secondly, such as Figures 1 to 3As shown, the supporting water pipe 3, connecting water pipe 4, and telescopic water pipe 5 are equipped with connecting mechanisms. The connecting mechanisms include a first external thread 41 located at the end of the connecting water pipe 4 near the nozzle 2345. The first external thread 41 engages with the inner wall thread of the supporting water pipe 3 at the end away from the spray pipe 2. This spiral connection secures the connecting water pipe 4 to the supporting water pipe 3, facilitating adjustment of the insertion length of the connecting water pipe 4 into the supporting water pipe 3. The first external thread 41 is spirally sleeved at the end of the supporting water pipe 3 away from the spray pipe 2. The telescopic water pipe 5 has a second external thread 51 located at the end near the nozzle 2345. The second external thread 51 engages with the inner wall thread of the connecting water pipe 4 at the end away from the supporting water pipe 3. This spiral connection secures the telescopic water pipe 5 to the connecting water pipe 4, facilitating adjustment of the insertion length of the telescopic water pipe 5 into the connecting water pipe 4, thereby changing the overall maintenance range of the device. The second external thread 51 is spirally sleeved at the end of the connecting water pipe 4 away from the supporting water pipe 3.

[0019] In addition, such as Figures 2 to 3 As shown, a first retaining ring 42 is fixedly connected to one end of the connecting water pipe 4 inserted into the supporting water pipe 3. When the connecting water pipe 4 is connected to the supporting water pipe 3, the first retaining ring 42 is tightly connected to the first rubber ring gasket 31 inside the supporting water pipe 3, achieving a seal and preventing the connecting water pipe 4 from excessively slipping out of the supporting water pipe 3. The supporting water pipe 3 also has a first rubber ring gasket 31 inside one end that is tightly connected to the first retaining ring 42. When the connecting water pipe 4 is inserted into the supporting water pipe 3, the first rubber ring gasket 31 is tightly connected to the first retaining ring 42 on the connecting water pipe 4, achieving a seal between the supporting water pipe 3 and the connecting water pipe 4, preventing water leakage at the pipe connection.

[0020] It is worth noting that, such as Figures 2 to 3 As shown, a second retaining ring 52 is fixedly connected to one end of the telescopic water pipe 5 inserted into the connecting water pipe 4. When the telescopic water pipe 5 is connected to the connecting water pipe 4, the second retaining ring 52 is tightly connected to the second rubber ring gasket 43 inside the connecting water pipe 4, achieving a seal and preventing the telescopic water pipe 5 from excessively dislodging from the connecting water pipe 4. A second rubber ring gasket 43 is provided inside one end of the connecting water pipe 4, which is tightly connected to the second retaining ring 52. When the telescopic water pipe 5 is inserted into the connecting water pipe 4, the second rubber ring gasket 43 is tightly connected to the second retaining ring 52 on the telescopic water pipe 5, achieving a seal between the connecting water pipe 4 and the telescopic water pipe 5, preventing water leakage at the pipe connection.

[0021] Furthermore, such as Figures 1 to 3As shown, the end of the telescopic water pipe 5 furthest from the connecting water pipe 4 is fixedly connected to a side nozzle 6. After receiving water from the telescopic water pipe 5, the side nozzle 6 sprays water onto the side or edge areas of the concrete, covering areas that are difficult for the nozzles 2345 to reach, achieving multi-dimensional curing of the concrete and preventing missed curing in the edge and side areas. A valve 7 is also provided at the end of the telescopic water pipe 5 near the side nozzle 6. The valve 7 controls the flow of water from the telescopic water pipe 5 to the side nozzle 6. When it is necessary to adjust the length of the device or pause the spraying of water from the side nozzle 6, the valve 7 can be closed, allowing for flexible operation and easy control of the working state of the side nozzle 6 according to curing needs. A pair of supporting water pipes 3, connecting water pipes 4, telescopic water pipes 5, side nozzles 6, and valves 7 are all symmetrically arranged around the spray pipe 2. The end of the supporting water pipe 3 furthest from the spray pipe 2 is tightly fitted with the end of the connecting water pipe 4, and the end of the connecting water pipe 4 furthest from the supporting water pipe 3 is tightly fitted with the end of the telescopic water pipe 5.

[0022] In this embodiment, when using the large-volume concrete curing device, the water supply pipe 1 is first connected to the external sprinkler. Then, the overall length of the device can be adjusted according to the size of the curing area: the connecting water pipe 4 is rotated so that it is spirally connected to the end of the supporting water pipe 3 away from the spray pipe 2 through the first external thread 41. At the same time, the part of the connecting water pipe 4 inserted into the supporting water pipe 3 will allow the first retaining ring 42 to be tightly connected to the first rubber ring gasket 31 inside the supporting water pipe 3, which not only achieves connection and fixation but also ensures a leak-proof seal through the first rubber ring gasket 31. Then, in the same way, the telescopic water pipe 5 is rotated so that it is spirally connected to the end of the connecting water pipe 4 away from the supporting water pipe 3 through the second external thread 51. The second retaining ring 52 of the telescopic water pipe 5 inserted into the connecting water pipe 4 is tightly connected to the second rubber ring gasket 43 inside the connecting water pipe 4, further extending the device and ensuring a seal.

[0023] After adjusting the length, open valve 7. The water delivered by the sprinkler will pass through water supply pipe 1, spray pipe 2, support water pipe 3, connecting water pipe 4, and telescopic water pipe 5 in sequence. Then, part of the water will be sprayed outward through the nozzles 2345 on the outer wall of spray pipe 2, support water pipe 3, connecting water pipe 4, and telescopic water pipe 5 to cure the main areas of the concrete surface. The other part of the water will be sprayed out through the side nozzles 6 at the end of telescopic water pipe 5 away from the connecting water pipe 4 to cover the side or edge areas that are difficult to reach by nozzles 2345, achieving multi-dimensional curing.

[0024] If the curing range needs to be adjusted, valve 7 can be closed, and the connecting water pipe 4 or telescopic water pipe 5 can be rotated in the reverse direction. The overall length of the device can be shortened by the spiral engagement of the first external thread 41 and the second external thread 51. After adjustment, valve 7 can be reopened to continue curing. The entire process does not require frequent movement of water supply pipelines or supports, which greatly reduces labor costs and labor intensity. At the same time, the cooperation of multi-position nozzles 2345 and side nozzles 6, as well as the leak-proof guarantee of the sealing structure, avoids the problem of missed curing caused by curing interruption, meets the need for continuous and uniform moisture retention of large-volume concrete, and reduces the risk of insufficient cement hydration and drying shrinkage cracks.

For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
