[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1As shown, the embodiment of the present application discloses a concrete sample curing device for testing, including: a device body 1, in which a humidifying assembly capable of spraying a spray is arranged; a rotating shaft 2, rotatably installed in the device body 1, and located on one side of the humidifying assembly; a placing component 3, made of a stainless steel welded mesh, arranged on the rotating shaft 2, and used for placing a concrete sample 8; a drainage component 4, arranged on the rotating shaft 2, and located above the placing component 3; a first arcuate surface 41, arranged on the drainage component 4, and the edge of the first arcuate surface 41 extends in a direction away from the rotating shaft 2, for directing water droplets to flow in a direction away from the rotating shaft 2; a driving motor 5, which is transmission-connected to the rotating shaft 2, and is used for driving the rotating shaft 2 to rotate.

[0019] In the utility model, the concrete sample 8 is placed by using a placement component 3 made of a stainless steel welded mesh, which can effectively reduce the area of ​​the outer surface of the concrete sample 8 that is covered, improve the air permeability of the concrete sample 8, ensure that the concrete sample 8 can fully contact the spray diffused in the air, and ensure that the humidity of the concrete sample 8 is uniform.

[0020] In this embodiment, by setting a first curved surface 41 above the placement part 3, the water droplets condensed from the spray can be guided through the first curved surface 41 to flow in a direction away from the rotating shaft 2, preventing the water droplets from directly falling on the concrete sample 8, further ensuring the uniformity of the humidity of the concrete sample 8 and ensuring the accuracy of the detection.

[0021] Reference Figure 2 As shown, the device also includes: a first mounting ring 31 and a second mounting ring 32, the first mounting ring 31 is arranged on the rotating shaft 2, and the storage component 3 is installed between the first mounting ring 31 and the second mounting ring 32; a support rod 33, which is also arranged between the first mounting ring 31 and the second mounting ring 32, and the storage component 3 is arranged on the support rod 33 in a wave shape.

[0022] The first mounting ring 31 , the second mounting ring 32 and the support rod 33 are provided to ensure the mounting stability of the storage component 3 and prevent the storage component 3 from being deformed by pressure.

[0023] By installing the placement component 3 in a wave shape, the surface-to-surface contact between the concrete sample 8 and the placement component 3 can be converted into line-to-surface contact, thereby further reducing the contact area between the concrete sample 8 and the placement component 3 .

[0024] It can be understood that the storage part 3 can be formed into a wavy shape by pressing the stainless steel welded mesh; of course, in order to ensure the strength, one storage part 3 can be formed by stacking several layers of stainless steel welded mesh.

[0025] Furthermore, a plurality of placement components 3 are arranged at fixed intervals on the rotating shaft 2 to increase the number of concrete samples 8 placed and improve the maintenance efficiency; along the axial direction of the rotating shaft 2, drainage components 4 are arranged on both sides of each placement component 3, and each placement component 3 is independent in the vertical direction to prevent water droplets on the upper concrete sample 8 from directly dripping onto the lower concrete sample 8, thereby avoiding the influence between the concrete samples 8.

[0026] Specifically, the device also includes: a second curved surface 42, arranged on the drainage component 4, for receiving water droplets and flowing the water droplets toward the rotating shaft 2; a recovery channel 21, opened in the rotating shaft 2 and extending toward the humidification component; a through hole 22, opened on the rotating shaft 2, one end facing the second curved surface 42, and the other end connected to the recovery channel 21.

[0027] In the present use model, by providing the second curved surface 42, the water droplets condensed from the spray in the maintenance equipment can be drained and gathered, and the water droplets are recovered through the recovery channel 21 and sent back to the humidification component, which can reduce losses and save resources.

[0028] Furthermore, the humidification component includes: a first delivery pipe 61, which is arranged in the equipment body 1; a plurality of atomizing nozzles 62, which are arranged on the first delivery pipe 61; a water tank 63 and a water pump 64, and the water pump 64 connects the first delivery pipe 61 and the water tank 63 through pipe fittings.

[0029] It can be understood that by delivering water to the first delivery pipe through the water pump 64 , the mist can be sprayed into the device body 1 through the atomizing nozzle 62 , so as to adjust the humidity in the device body 1 .

[0030] It is worth mentioning that the recovery channel 21 is arranged toward the water tank 63 , and the received water droplets are collected and flowed toward the water tank 63 .

[0031] Furthermore, the device also includes: a second conveying pipeline 71, which is arranged in the equipment body 1; a plurality of air outlets 72, which are opened on the second conveying pipeline 71; a fan 73, which is connected to the second conveying pipeline 71 through a pipe fitting; and a resistance wire (not shown in the figure), which is arranged between the fan 73 and the second conveying pipeline 71.

[0032] Specifically, air is blown into the device body 1 by the fan 73 and heated by the resistance wire, which can accelerate the evaporation of water in the device body 1, thereby adjusting the dryness in the device body 1.
