Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of concrete maintenance, especially to a concrete maintenance intelligent temperature control device. BACKGROUND

[0002] In the building engineering quality detection system, the maintenance quality of the concrete test block directly determines the accuracy of its strength, durability and other key performance indicators, and is an important basis for evaluating the quality of concrete entity. At present, the maintenance of the concrete test block mostly adopts the traditional maintenance method, and these methods have many problems in practical application.

[0003] Most laboratories or construction sites still use simple curing rooms or curing pools for test block maintenance. The temperature in the curing room is usually adjusted by ordinary heating and refrigeration equipment. Due to the lack of precise temperature monitoring and control mechanism, the indoor temperature is unevenly distributed, and there is a large difference in the curing temperature of test blocks at different positions, which affects the final strength of the test block and makes the test block detection result unable to truly reflect the quality of the concrete entity.

[0004] Although some curing environments are equipped with temperature and humidity control equipment, these equipment are mostly manually operated and parameterized. During the actual curing process, the staff needs to check and manually adjust the equipment regularly, which not only has high labor intensity, but also is difficult to ensure the timeliness and accuracy of temperature adjustment.

[0005] In addition, with the increasing strictness of the building industry on engineering quality control and the continuous refinement of detection standards, the control precision and stability of the concrete test block curing temperature are increasingly required. The frequent entry and exit of the staff in the curing room during the operation process of the traditional curing method will cause the temperature and humidity in the room to change, thereby affecting the detection accuracy.

[0030] As one implementation method in this embodiment, in order to achieve a uniform cooling temperature within the curing chamber 2, such as... Figure 3 As shown, multiple cooling holes 20 are arrayed on the right side wall of the curing chamber 2, and a cooling box 6 is provided on the right outer wall of the curing chamber 2. One side of the cooling box 6 is connected to the inner cavity of the curing chamber 2 through the cooling holes 20, and the other side of the cooling box 6 is connected to a cooling pipe.

[0031] As one implementation method in this embodiment, to uniformly and stably regulate the humidity within the curing chamber 2, such as... Figure 3 , Figure 5 As shown, the bottom array of the maintenance chamber 2 is provided with multiple sets of humidification holes 21, and the bottom of the maintenance chamber 2 is provided with a humidification box 7. The top surface of the humidification box 7 is connected to the inner cavity of the maintenance chamber 2 through the humidification holes 21.

[0032] As one implementation method in this embodiment, to facilitate the stable pulling out of the placement frame 9, such as Figures 3 to 5 As shown, multiple sets of support wheels 90 are symmetrically arranged at the bottom of the placement frame 9.

When the temperature is higher than the set temperature, the control panel 10 controls the cooler 4 to work and simultaneously opens the cooling solenoid valve 40, allowing cold air to enter the maintenance chamber 2 through the cooling pipe, cooling box 6, and cooling hole 20 for cooling. Regarding humidity, when the humidity is lower than the set value, the control panel 10 controls the humidifier 5 to work and simultaneously opens the humidification solenoid valve 50, allowing water mist to enter the maintenance chamber 2 through the humidification pipe, humidification box 7, and humidification hole 21 to increase the humidity. When the humidity is too high, the control panel 10 controls the window exhaust fan 8 to start, expelling excess water mist through the exhaust pipe 22.
