[0002] In the field of concrete curing technology, existing concrete curing devices often have some limitations in practical applications.

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] In one embodiment, Figures 1-9 As shown, an intelligent concrete curing device includes a curing box 1, a door 11 is hinged at the front end of the curing box 1, a fixing block 2 3 and a fixing block 1 2 are fixed on the left and right sides of the curing box 1, and a placement structure 6 for placing a concrete test block is installed between the fixing block 2 3 and the fixing block 1 2;

[0035] An adjustment cavity 4 is provided inside the fixing block 2 3 and the fixing block 1 2. Adjustment openings 40 are symmetrically provided at opposite ends of the fixing block 2 3 and the fixing block 1 2. An adjustment structure 5 for adjusting the distance between each two placement structures 6 is provided inside the adjustment cavity 4.

[0036] The placement structure 6 includes a placement frame 61, on which a smoothing structure 7 is provided for smoothing the water vapor condensed on the concrete test block. A plurality of support rods 62 are fixed equidistantly inside the placement frame 61. Connecting blocks 64 are symmetrically fixed on the left and right sides of the placement frame 61. The outer wall of the connecting block 64 slides with the inner wall of the adjustment port 40. The end of the connecting block 64 away from the placement frame 61 extends through the adjustment port 40 to the inside of the adjustment cavity 4 and is connected to the adjustment structure 5. Side blocks 63 are symmetrically fixed on both sides of the front and rear ends of the placement frame 61.

[0037] The curing box 1 is provided with a curing structure 9 for curing the concrete test blocks inside, and the upper end of the curing box 1 is provided with a driving structure 8 for providing power to the leveling structure 7 and the curing structure 9.

[0038] In this embodiment, the concrete test block is placed on the placement rack 61, and several support rods 62 equidistantly fixed in the placement rack 61 serve to support the concrete test block; then, according to the number of concrete test blocks and the curing requirements, the connecting block 64 can be driven to slide in the adjustment port 40 through the adjustment structure 5, so that the placement rack 61 moves between the fixed block 2 3 and the fixed block 1 2, so as to adjust the distance between each two placement structures 6 to meet the needs of different curing scenarios; next, the curing structure 9 set inside the curing box 1 starts to work to cure the concrete test block placed on the placement structure 6; during the curing process, water vapor will condense on the surface of the concrete test block. At this time, the smoothing structure 7 set on the placement rack 61 starts to work to smooth the water vapor condensed on the concrete test block.

[0039] In an optional embodiment, a movable cavity 46 is provided on the fixed block 23, and the smoothing structure 7 includes a guide rod 76 fixed between the two side blocks 63 at the front end and a screw 77 rotatably installed between the two side blocks 63 at the rear end. A movable block 2 72 slides on the guide rod 76, and the screw 77 is threadedly connected to the movable block 1 71. Fixed support plates 73 are symmetrically fixed to the upper and lower ends of the movable block 1 71 and the movable block 2 72. A fixed frame 74 is fixed between the two fixed support plates 73, and a roller 75 is rotatably installed on the end of the fixed frame 74 close to the placement frame 61. One end of the movable block 1 71 extends to the inside of the movable cavity 46 and is fixedly connected to a gear 1 78, and the gear 1 78 is meshed with a rack 1 79. A through-hole 2 47 is provided on the upper end of the fixed block 2 3, and a through-hole 14 is provided on the upper end of the curing box 1. The rack 1 79 passes through the through-hole 2 47 and the through-hole 14 in sequence and extends to the upper end of the curing box 1 and is connected to the driving structure 8.

[0040] It should be noted that when the driving structure 8 drives the rack 1 79 to make a reciprocating linear motion up and down, since the gear 1 78 is engaged with the rack 1 79, the gear 1 78 will automatically rotate forward and reverse in the movable chamber 46, thereby driving the moving block 1 71 to make a reciprocating threaded motion on the screw 77; at the same time, the moving block 2 72 slides on the guide rod 76 to provide a guide for the movement of the moving block 1 71 and ensure the stability of the movement; the moving blocks 1 71 and the moving blocks 2 72 drive the fixed frame 74 to move through the fixed support plate 73, so that the roller 75 moves on the concrete The surface of the test block is rolled to smooth out the condensed water vapor on the concrete test block, avoiding surface cracks of the concrete test block caused by water vapor accumulation. The smoothing operation can temporarily close the micropores on the surface of the test block, slow down the evaporation rate of water, extend the effective curing time, and ensure that the concrete obtains sufficient strength growth in the early stage. The smoothing operation can also reduce the local accumulation of water vapor on the surface of the test block, avoid uneven curing due to humidity differences, and a uniform humidity environment is conducive to the full progress of the cement hydration reaction, thereby improving the ultimate strength and durability of the concrete test block.

[0041] In an optional embodiment, the driving structure 8 includes an automatic reversing unit 81 and a motor 2 801 installed at the upper end of the maintenance box 1, the output end of the motor 2 801 is fixedly connected to the gear 2 802, the gear 2 802 is meshed with the gear 3 803, and a driving rod 804 is fixed at a position deviating from the center of the upper end of the gear 3 803, the driving rod 804 is connected to the rack 1 79 through the automatic reversing unit 81, and the driving rod 804 is connected to the maintenance structure 9.

[0042] It should be noted that after the motor 2 801 is started, it drives the gear 2 802 to rotate. Since the gear 2 802 is engaged with the gear 3 803, the gear 3 803 rotates accordingly; the driving rod 804 is fixed at a position deviated from the center of the circle at the upper end of the gear 3 803, so when the gear 3 803 rotates, the driving rod 804 will perform a circular motion; through the automatic reversing unit 81, the circular motion of the driving rod 804 can be converted into the up and down reciprocating linear motion of the rack 1 79, thereby providing power for the leveling structure 7; at the same time, the driving rod 804 is also connected to the maintenance structure 9, and can provide power for the maintenance structure 9, realizing the function of a driving source driving the leveling structure 7 and the maintenance structure 9 to work at the same time, simplifying the structure of the device and reducing costs.

[0043] In an optional embodiment, the automatic reversing unit 81 includes an L-shaped rod 811, which is provided with a reversing port 8111 that cooperates with the driving rod 804. A rack 2 8112 is fixed to the bottom of the other end of the L-shaped rod 811, and the rack 2 8112 is meshed with the gear 4 812. The gear 4 812 is fixedly connected to the gear 5 814 through a synchronization rod 813. The gear 5 814 is rotatably mounted on the fixed plate 15, and the fixed plate 15 is fixed to the upper end of the maintenance box 1.

[0044] It should be noted that when the drive rod 804 performs circular motion, it slides within the reversing opening 8111, driving the L-shaped rod 811 to perform reciprocating linear motion. Since rack 2 8112 is fixed to the bottom of the other end of the L-shaped rod 811, rack 2 8112 also performs reciprocating linear motion, thereby driving gear 4 812 to rotate forward and reverse. Gear 4 812 then drives gear 5 814 to rotate forward and reverse synchronously via synchronization rod 813. Gear 5 814 meshes with rack 1 79, thereby achieving the up and down reciprocating linear motion of rack 1 79. This automatic reversing unit has a simple and reliable structure and can accurately convert the circular motion of the drive rod 804 into the reciprocating linear motion of rack 1 79, ensuring the normal operation of the leveling mechanism 7.

[0045] In an optional embodiment, the maintenance structure 9 includes a steam cylinder 903, a push rod 907 and a spraying unit 91, one end of the push rod 907 is rotatably connected to the drive rod 804, and the other end of the push rod 907 is rotatably connected to the hinge block 906, and the other end of the hinge block 906 extends to the interior of the steam cylinder 903 through the piston rod 905 and is fixedly connected to the piston block 9051. The interior of the steam cylinder 903 is connected to the interior of the steam generator 901 through the steam supply pipe 902, and the steam cylinder 903 is connected to the spraying unit 91 through the steam blowing pipe 904 and the fixed pipe 45. Steam one-way valves are installed on the steam supply pipe 902 and the steam blowing pipe 904.

[0046] It should be noted that when the drive rod 804 performs circular motion, it drives the push rod 907 to swing back and forth. The push rod 907, through the hinge block 906 and the piston rod 905, drives the piston block 9051 to perform reciprocating linear motion within the steam cylinder 903. When the piston block 9051 moves away from the steam supply pipe 902, a negative pressure is formed within the steam cylinder 903, and the steam generated by the steam generator 901 enters the steam cylinder 903 through the steam supply pipe 902. When the piston block 9051 moves toward the steam supply pipe 902, the steam within the steam cylinder 903 is compressed and enters the spray unit 91 through the steam blowing pipe 904 and the fixed pipe 45. Finally, the spray unit 91 sprays the steam onto the concrete test block, thereby curing the concrete test block. The function of the steam check valve is to ensure that steam can only flow in one direction, prevent steam backflow, and ensure the normal operation of the curing structure 9.

[0047] In an optional embodiment, the spray unit 91 includes a movable block 911 that is slidably connected to the outer wall of the fixed tube 45, a steam vent 451 is provided on the side wall of the fixed tube 45, a baffle 453 that blocks the steam vent 451 is slidably installed inside the fixed tube 45, a contact plate 452 is fixed to the lower end of the baffle 453, the lower end of the contact plate 452 contacts the upper end of the movable block 911, movable ports 912 are symmetrically provided on both sides of the movable block 911, the movable block 911 is connected to the adjustment structure 5 through the movable ports 912, the movable block 911 is connected to another movable block 911 through a spray rod 913, the other movable block 911 slides with the fixed rod 44, the fixed rod 44 and the fixed tube 45 are respectively fixed in two adjustment chambers 4, the fixed tube 45 is connected to the spray rod 913 through the steam vent 451, and a plurality of atomizing nozzles 914 are provided on the spray rod 913.

[0048] It should be noted that when the adjustment structure 5 is working, it will drive the movable block 911 to slide on the outer wall of the fixed tube 45 and the fixed rod 44. When the movable block 911 slides, it will push the contact plate 452, and then drive the baffle 453 to slide in the fixed tube 45, so that the steam vent 451 is opened or closed. When the steam vent 451 is open, the steam in the steam cylinder 903 enters the spray rod 913 through the fixed tube 45 and the steam vent 451, and is finally sprayed onto the concrete test block by the atomizing nozzle 914. By sliding the movable block 911, the opening of the steam vent 451 can be controlled, thereby adjusting the spraying amount and spraying range of the steam, and achieving more precise maintenance. At the same time, the spray rod 913 is connected to the movable block 911, and the sliding of the movable block 911 will also drive the spray rod 913 to move, so that the steam can be sprayed more evenly onto the surface of the concrete test block.

[0049] In an optional embodiment, an adjusting slot 43 is provided at the lower end of the adjusting chamber 4, a motor slot 42 is provided on one side of the adjusting slot 43, and a fixing rod 44 and a fixing tube 45 are provided inside the adjusting chamber 4 of the fixing block 2 3 and the fixing block 1 2 respectively; the adjusting structure 5 includes a motor 1 501 installed inside the motor slot 42, the output end of the motor 1 501 extends to the inside of the adjusting slot 43 and is fixedly connected to a bidirectional screw 502, and two adjusting blocks 1 503 are slidably installed inside the adjusting slot 43, and the two adjusting blocks 1 503 are respectively threadedly connected to the two ends of the bidirectional screw 502, and the adjusting block 1 503 A fixing ear 504 is fixed at the upper end, one of the fixing ears 504 is hinged to one end of the adjustment plate 1 511, and the other fixing ear 504 is hinged to one end of the adjustment plate 2 513. The other ends of the adjustment plate 1 511 and the adjustment plate 2 513 are rotatably connected to the other adjustment plate 2 513 and the other adjustment plate 1 511 respectively through the rotating shaft 2 514. The rotating shaft 2 514 slides with the movable opening 912. Each of the adjustment plates 1 511 is hinged to the middle part of the adjustment plate 2 513 through the rotating shaft 1 512. The end of the rotating shaft 1 512 away from the adjustment chamber 4 is fixedly connected to the placement rack 61 through the connecting block 64.

[0050] It should be noted that after the motor 501 is started, it drives the bidirectional screw 502 to rotate. Since the two adjustment blocks 503 are respectively threadedly connected to the two ends of the bidirectional screw 502, the two adjustment blocks 503 will move toward or away from each other within the adjustment slot 43. The adjustment block 503 drives the adjustment plate 1 511 and the adjustment plate 2 513 to move through the fixed ear 1 504. The adjustment plate 1 511 and the adjustment plate 2 513 are hinged to each other through the rotating shaft 1 512 and the rotating shaft 2 514, forming a structure similar to a scissors fork. When the two adjustment blocks 503 move toward each other, the distance between the two adjacent placement racks 61 is increased; when the two adjustment blocks 503 move away from each other, the distance between the two adjacent placement racks 61 is decreased. In this way, the distance between each two placement structures 6 can be precisely adjusted to meet the maintenance requirements of different concrete test blocks. At the same time, the second rotating shaft 514 slides with the movable opening 912, so that the movement of the adjustment structure 5 can be coordinated with the movement of the spraying unit 91, ensuring the overall coordination of the device.

[0051] In an optional embodiment, guide grooves 41 are symmetrically provided on both sides of the adjustment cavity 4, a slide plate 524 slides inside the guide groove 41, a cross bar 523 is fixed between the two slide plates 524, two adjustment blocks 522 slide symmetrically on the cross bar 523, a fixing ear 2 521 is fixed at the lower end of the adjustment block 2 522, one fixing ear 2 521 is hinged to one end of the adjustment plate 1 511, and the other fixing ear 2 521 is hinged to one end of the adjustment plate 2 513.

[0052] It should be noted that the slide plate 524 slides within the guide groove 41, providing guidance for the movement of the crossbar 523 and ensuring the stability of the movement direction of the crossbar 523. The second adjustment block 522 slides on the crossbar 523 to accommodate the changes in the angle of the adjustment plate 1 511 and the adjustment plate 2 513 during movement. The second fixing ear 521 connects the second adjustment block 522 to the adjustment plate 1 511 and the adjustment plate 2 513, making the adjustment plate 1 511 and the adjustment plate 2 513 more stable during movement, improving the stability and reliability of the adjustment structure 5 and further ensuring the accuracy of the movement of the placement rack 61.

[0053] In an optional embodiment, a temperature sensor 12 and a humidity sensor 13 are installed inside the curing box 1 .

[0054] It should be noted that the temperature sensor 12 and the humidity sensor 13 can monitor the temperature and humidity inside the curing box 1 in real time, which is helpful for judging whether the temperature and humidity inside the curing box 1 are appropriate.

[0055] The above embodiment discloses an intelligent concrete curing device, in which concrete test blocks are placed on a placement rack 61 in a curing box 1, with support rods 62 serving as support. Depending on the number of concrete test blocks and curing requirements, the bidirectional screw 502 is driven to rotate by motor 1 501, thereby driving the adjustment block 1 503 to slide in the adjustment slot 43. The sliding of the adjustment block 1 503 is converted into movement of the placement rack 61 between the fixed block 1 2 and the fixed block 2 3 through the hinged structure of the adjustment plate 1 511 and the adjustment plate 2 513, thereby adjusting the distance between each two placement structures 6.

[0056] The maintenance structure 9 starts working, the motor 2 801 starts, driving the gear 2 802 and the gear 3 803 to rotate; the driving rod 804 on the gear 3 803 performs a circular motion, driving the piston block 9051 to perform a reciprocating linear motion in the steam cylinder 903 through the push rod 907 and the piston rod 905; the reciprocating motion of the piston block 9051 creates negative pressure and positive pressure in the steam cylinder 903, thereby sucking steam from the steam generator 901 through the steam supply pipe 902, and delivering the steam to the spray unit 91 through the steam blowing pipe 904 and the fixed pipe 45; the movable block 911 in the spray unit 91 is driven by the adjustment structure 5 to slide on the outer wall of the fixed pipe 45 and the fixed rod 44, thereby controlling the opening of the steam vent 451 and adjusting the steam spraying amount and spraying range.
