[0028] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0029] 1. A low-energy heat preservation and moving mechanism is set up. The low-energy heat preservation and moving mechanism pushes the pipe laying frame up and down through the cooperation of electric hydraulic cylinders, telescopic rods and splicing plates to fit the concrete surface. The heating rods on the positioning plate are then used to heat the water inside the heating water tank. The heated water is then transported to the inside of the pipe laying frame, which facilitates heating and heat preservation of the concrete surface, prevents the concrete from freezing and cracking, ensures high-quality maintenance of the concrete even in severely cold areas, and improves the durability and frost resistance of the concrete.

[0030] At the same time, the first water pump, water supply hose, cross pipe and heat exchange pipe cooperate to distribute hot water inside the pipe laying frame, which increases the uniformity of concrete heating. At the same time, the cooperation of the cover plate and thermal insulation pad can not only slow down the heat loss inside the pipe laying frame, but also prevent the temperature from being too high, reducing the phenomenon of concrete drying.

[0031] In addition, during the lifting and lowering process of the pipe laying frame, the water supply hose can be supported and limited by the cooperation of the splicing plate, vertical plate, limit rod and anti-deflection ring, preventing the water supply hose from being tangled together and ensuring the water supply effect.

[0032] 2. The water recovery tank, the second water pump and the return pipe are arranged to facilitate the re-transport of the heat-exchanged water to the heating water tank, so as to recycle the water with residual heat and improve the utilization rate of resources. In areas with sufficient sunlight, the three-way valve is turned to allow the water to pass through the branch pipe into the diversion pipe and the solar heating pipe, so as to heat the water with solar energy, thereby increasing the water temperature. The hot water circulation and solar energy are used together for auxiliary heating, thus reducing energy consumption.

[0033] Through the cooperation of the insulation board, N-shaped frame, adjustment rod, lifting slide and support wheel, the lightweight aluminum alloy frame can be easily pushed to move, and the position of the pipe laying frame can be adjusted to facilitate continuous use. There is no need for frequent disassembly and installation of pipes, which saves construction steps and improves convenience.

[0034] 3. An automatic spraying and water replenishing mechanism is set up. The electric slide rail pushes the translation frame, spray barrel and atomizing spray pipe to move, and at the same time separates the touch switch from the partition, restores the power supply to the electromagnet, and makes the two electromagnets repel each other, pushing the top plate, movable rod and water plug to rise, releasing the seal of the atomizing spray pipe, and facilitating the water inside the spray barrel to be sprayed out through the atomizing spray pipe, thus ensuring the humidity of the concrete surface, preventing the phenomenon of drying and cracking, improving the quality of maintenance, and improving the early strength and durability;

[0035] When the translation frame moves to the other side of the electric slide rail, the touch switch fits against the partition, shutting off the power supply to the electric slide rail and the electromagnet, stopping the electric slide rail and making the electromagnet lose its magnetism. The support spring then pushes the water plug, the movable rod and the top plate to reset, resealing the atomizing spray pipe and stopping spraying. This achieves the effect of moving spraying and stopping sealing, and increases the degree of automation of the device.

[0036] By embedding one end of the water inlet pipe into the retaining ring inside the water outlet pipe, the inner wall of the retaining ring is tightly fitted with the outer side of the water outlet pipe, and the movable plug is pushed to move to release the seal of the water outlet pipe. At the same time, the push rod also pushes the sealing plug to slide and shrink inside the water inlet pipe, releasing the seal of the water inlet pipe, making it convenient for the water inside the water storage tank to enter the interior of the spray barrel through the vertical pipe, the water outlet pipe and the water inlet pipe, and automatically replenished, thereby ensuring the effect of subsequent spraying and reducing people's operation.

[0037] In summary, through the cooperation of low-energy thermal insulation and mobile mechanisms and automatic spraying and water replenishment mechanisms, heating, insulation and automatic spraying are achieved, which ensures the maintenance quality of concrete in cold areas, increases the durability and frost resistance of concrete, reduces the demand for workers, and improves convenience. At the same time, two auxiliary heating methods, solar energy and waste heat recovery, are set up to reduce energy consumption and save costs. In addition, the entire device can be moved for convenient continuous use without the need for frequent disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

A movable plug 520 is movably sleeved on the outer side of the push rod 519 corresponding to the position on one side of the retaining ring 517, and a return spring 521 is clamped between the movable plug 520 and the connecting plate 518 at the outer position of the push rod 519 corresponding to the outer side of the push rod 519. In order to facilitate the automatic replenishment of water into the spray barrel 506, the axis of the water outlet pipe 515 and the axis of the water inlet pipe 516 are located on the same horizontal line. The retaining ring 517 is a waterproof rubber ring, and the inner diameter of the retaining ring 517 inside the water outlet pipe 515 is larger than the outer diameter of the water inlet pipe 516, and the outer diameter of the push rod 519 is smaller than the inner diameter of the retaining ring 517 inside the water inlet pipe 516;

[0069] A cross plate 522 is clamped on the inner wall of the water inlet pipe 516, and a sliding rod 523 is movably connected inside the cross plate 522. A sealing plug 524 is clamped on one end of the sliding rod 523 at a position corresponding to one side of the retaining ring 517, and a return spring 521 is clamped on the outer position of the sliding rod 523 between the sealing plug 524 and the cross plate 522.

[0070] According to the above technical solution, an application for improving the early strength of concrete and improving its durability and frost resistance is provided, and a system for improving the early strength of concrete and improving its durability and frost resistance is provided for use in concrete and prefabricated floor slabs.

[0071] The working principle and usage process of the present invention are as follows: First, through the cooperation of the insulation board 432, the N-shaped frame 433, the adjustment rod 434, the lifting slide 435 and the support wheel 410, the lightweight aluminum alloy frame 1 is conveniently moved to the top of the concrete that needs to be cured. Then, the adjustment rod 434 is rotated to move the lifting slide 435 and the support wheel 410 upward, thereby changing the height of the lightweight aluminum alloy frame 1, so that the bottom end of the insulation board 432 is in contact with the ground, reducing the gap. At the same time, the insulation tarpaulin 2 and the insulation curtain 3 are installed on the lightweight aluminum alloy frame 1 to keep warm and prevent wind, thereby reducing heat loss.

[0072] Next, the electric hydraulic cylinder 403 pushes the telescopic rod 404, the splicing plate 405 and the pipe laying frame 406 downward, so that the pipe laying frame 406 is in contact with the concrete surface. Then, the heating rod 409 on the positioning plate 408 is used to heat the water in the heating water tank 407 to increase the water temperature. Then, the hot water is transported to the horizontal pipe 416 inside the pipe laying frame 406 through the first water pump 411 and the water supply hose 412, and flows evenly into the heat exchange pipe 417, thereby evenly distributing the heat inside the pipe laying frame 406, uniformly heating and insulating the concrete, facilitating high-quality maintenance of concrete in severely cold regions, preventing freezing damage to the concrete caused by the cold temperature, and increasing the frost resistance of the concrete.

[0073] In addition, the cover plate 418 installed by bolts facilitates the protection of the pipes inside the pipe laying frame 406. At the same time, the threaded cylinder 419, the latch 420 and the limiting clamping plate 421 cooperate to clamp the thermal insulation pad 422 at the top and bottom of the pipe laying frame 406, which not only slows down the loss of heat inside the pipe laying frame 406, but also prevents the temperature from being too high and causing the concrete to dry out too much.

[0074] Next, the heat-exchanged water is transported to the interior of the recovery water tank 423 through the cooperation of another horizontal pipe 416 and the water supply hose 412. It is then transported back to the interior of the heating water tank 407 through the cooperation of the second water pump 425 and the return pipe 424. This facilitates the recycling of the water with residual heat, improves resource utilization, and reduces the power consumption of the heating rod 409.

[0075] In addition, in areas with sufficient sunlight, the three-way valve 431 is turned to allow the water in the return pipe 424 to enter the branch pipe 430, forcing the water to be transported to the diversion pipe 427 and evenly flow into the solar heating pipe 428, thereby heating the water with solar energy to increase the water temperature. The water is then transported back to the heating water tank 407 through the connecting pipe 429, so that the hot water circulation and solar energy are used for auxiliary heating together, further reducing energy consumption. At the same time, the solar heating pipe 428 is installed at an angle, which allows water to remain inside when not in use, preventing it from freezing.

[0076] In addition, when the pipe laying frame 406 rises, the splicing plate 405 pushes the vertical plate 413 to slide, and the water supply hose 412 is lifted and limited by the cooperation of the limit rod 414 and the anti-deflection ring 415. When the pipe laying frame 406 descends, the splicing plate 405, the vertical plate 413, and the limit rod 414 bring the water supply hose 412 down, preventing the water supply hose 412 from being tangled together, thereby ensuring the water supply effect.

[0077] Then, the state of the concrete is regularly observed. When it becomes dry, the electric hydraulic cylinder 403 is remotely activated to pull the telescopic rod 404, the splicing plate 405 and the pipe laying frame 406 up to the top of the electric slide rail 501. Then, with the cooperation of the electric slide rail 501, the translation frame 502 is pushed to slide with the spray barrel 506 and the atomizing spray pipe 507 inside the lightweight aluminum alloy frame 1. After the translation frame 502 moves, the touch switch 503 is separated from the partition 504, and the power supply to the electromagnet 512 is restored, so that the two electromagnets 512 repel each other, thereby pushing the top plate 511, the movable rod 508 and the water plug 509 to rise, releasing the seal of the atomizing spray pipe 507, and facilitating the spraying of water through the atomizing spray pipe 507, thereby ensuring the humidity of the concrete surface, preventing the phenomenon of drying and cracking, improving the quality of maintenance, and improving the early strength and durability.

[0078] In addition, when the translation frame 502 moves with the spray barrel 506 to the other side of the electric slide rail 501, the touch switch 503 is in contact with the partition 504, shutting off the power supply of the electric slide rail 501 and the electromagnet 512, so that the electric slide rail 501 stops moving and the electromagnet 512 loses its magnetism. Then, through the expansion and contraction characteristics of the support spring 510, the water plug 509, the movable rod 508 and the top plate 511 are pushed down and reset, resealing the atomizing spray pipe 507 and stopping spraying. This achieves the effect of moving spraying and stopping sealing, thereby increasing the degree of automation of the device.

[0079] Finally, when the translation frame 502 moves with the spray barrel 506 to the other side of the electric slide rail 501, one end of the water inlet pipe 516 is embedded in the retaining ring 517 inside the water outlet pipe 515, forcing the inner wall of the retaining ring 517 to fit tightly with the outer side of the water outlet pipe 515, reducing the occurrence of gaps and water leakage. As the translation frame 502 continues to move, the water inlet pipe 516 is embedded in the water outlet pipe 515, pushing the movable plug 520 to move, releasing the seal on the water outlet pipe 515, and at the same time, the push rod 519 also pushes the sealing plug 524 to slide and shrink inside the water inlet pipe 516, releasing the seal on the water inlet pipe 516, making it convenient for the water inside the water storage tank 513 to enter the interior of the spray barrel 506 through the vertical pipe 514, the water outlet pipe 515 and the water inlet pipe 516, so as to be replenished in time and ensure the effect of subsequent spraying.

[0080] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
