DETAILED DESCRIPTION

[0025] The embodiment of the present invention provides a constant temperature curing device for precast concrete components, such as Figure 1-6 As shown, it includes an upper shell 11, a lower shell 12, a first cavity 13, a first opening 14, a maintenance base 15, a maintenance cover 16, a second cavity 17, a humidifier shell 18, a third cavity 19, a preheating resistor 20, a nano-scale water vapor generator 21, a steam outlet pipe 22, a first slot 23, a second opening 24, a heating rod 25, an adjustment base 26, a first slider 27, a first fixed block 28, a second slider 29, a second fixed block 30, a first contact 31, a second contact 32, a third opening 33, a first limit block 34, a second limit block 35, a spring 36, a blocking plate 37, a fourth cavity 38, a fifth cavity 39, and a second slot 40.

[0027] The temperature control component includes an adjusting base 26, a first slider 27 and a first fixed block 28. The first slider 27 is slidably connected to the adjusting base 26, and the first fixed block 28 is fixedly connected to the adjusting base 26. A second slider 29 is also slidably connected in the adjusting base 26. The second slider 29 is arranged on a side of the first fixed block 28 away from the first slider 27. A second fixed block 30 is also fixedly connected in the adjusting base 26. The second fixed block 30 is fixedly connected to the adjusting base 26. The second fixed block 30 is arranged at one end of the second slider 29 away from the first fixed block 28, and one end of the adjusting base 26 close to the second fixed block 30 is connected to the second cavity 17.

[0028] A third opening 33 is provided on the first fixed block 28, a first limit block 34 is fixedly connected to a side of the first fixed block 28 close to the second sliding block 29, a second limit block 35 is fixedly connected to an end of the first limit block 34 away from the first fixed block 28, a spring 36 is sleeved on the outer circumferential surface of the first limit block 34, one end of the spring 36 is fixedly connected to the second limit block 35, and the other end of the spring 36 is fixedly connected to a blocking plate 37.

[0029] A surface of the second slider 29 close to the second fixed block 30 is fixedly connected with a plurality of first contacts 31 , a surface of the second fixed block 30 close to the second slider 29 is fixedly connected with a plurality of second contacts 32 , the first contacts 31 are electrically connected to the second contacts 32 , and the second contacts 32 are electrically connected to the heating rod 25 .

[0030] A second slot 40 is provided on a side of the third opening 33 away from the second limit block 35. The second slot 40 is arranged on a side of the first fixed block 28 close to the sealing plate 37. The first slider 27 and the adjustment base 26 surround a fourth cavity 38. The first slider 27 and the second slider 29 surround a fifth cavity 39. The fourth cavity 38 is filled with thermosensitive gas, and the fifth cavity 39 is filled with damping oil.

[0031] The humidification component includes a humidifier housing 18, a preheating resistance wire 20 and a nano-scale water vapor generator 21. A third cavity 19 is opened in the humidifier housing 18. The preheating resistance wire 20 is fixedly connected to the two side walls of the third cavity 19. The nano-scale water vapor generator 21 is fixedly connected to the third cavity 19. The nano-scale water vapor generator 21 is connected to a steam outlet pipe 22. The end of the steam outlet pipe 22 away from the nano-scale water vapor generator 21 passes through the first groove 23 and is fixedly connected to the second opening 24. It is worth noting that the preheating resistance wire 20, the nano-scale water vapor generator 21 and the heating rod 25 are all prior art.

[0032] The first openings 14 are arranged in several rows, and the first openings 14 in several rows are arranged at equal distances. The first openings 14 in the same row are arranged at equal distances. It is worth noting that in the present embodiment, the heating rod 25 is only arranged in one row of the first openings 14. In actual operation, the heating rod 25 can be arranged in several rows of the first openings 14. The heating rod 25 arranged in the first openings 14 can also play a role in temperature compensation for the water vapor in the steam outlet pipe 22.

[0033] When the present scheme performs constant temperature curing of precast concrete components, first, the precast concrete components are placed in the second cavity 17, the curing upper cover 16 is buckled onto the curing base 15, the upper shell 11 is buckled onto the lower shell 12, and the preheating resistance wire 20, the nano-scale water vapor generator 21 and the heating rod 25 are started. The nano-scale water vapor generator 21 sends nano-scale water vapor into the second cavity 17 through the steam outlet pipe 22, the preheating resistance wire 20 preheats the nano-scale water vapor sent into the second cavity 17 by the nano-scale water vapor generator 21, and the heating rod 25 heats the air in the second cavity 17. Since the first slot 23 connects the first cavity 13 and the second cavity 17, the temperature in the second cavity 17 is equal to the temperature in the first cavity 13.

[0034] Then, when the temperature in the second cavity 17 is too high, the volume of the thermosensitive gas in the fourth cavity 38 increases rapidly, thereby pushing the first slider 27 to slide in the direction of the first fixed block 28. The first slider 27 pushes the damping oil in the fifth cavity 39 from the side of the first fixed block 28 close to the first slider 27 to the side of the first fixed block 28 close to the second slider 29 through the third opening 33, thereby pushing the second slider 29 to slide in the direction of the second fixed block 30. The second slider 29 drives the first contact 31 to slide in the direction of the second fixed block 30 until the first contact 31 contacts the second contact 32. The second contact 32 generates an electrical signal to the heating rod 25, causing the heating rod 25 to stop working.

[0035] Finally, when the temperature in the second cavity 17 returns to normal, the volume of the thermosensitive gas in the fourth cavity 38 decreases, thereby pulling the first slider 27 to slide in the direction away from the first fixed block 28, and the damping oil in the fifth cavity 39 is pushed from the side of the first fixed block 28 close to the second slider 29 to the side of the first fixed block 28 close to the first slider 27 through the third opening 33, thereby pushing the second slider 29 to slide in the direction of the first fixed block 28, and the first contact 31 is separated from the second contact 32, and the second contact 32 generates an electrical signal to the heating rod 25, so that the heating rod 25 resumes working.

[0036] Thereby, the temperature inside the curing upper cover 16 is kept stable, thereby improving the curing effect of the precast concrete components.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
