Description

Technical Field

[0001] The utility model relates to the technical field of building material maintenance, in particular to a drawer-type concrete test piece intelligent maintenance cabinet. Background Art

[0002] Concrete materials are widely used in housing construction, transportation, water conservancy, municipal administration and other fields, which greatly promotes the process of urbanization in my country. Since concrete specimens are mixed with cement, sand, stone, water, admixtures, admixtures and other materials, and the performance requirements of concrete materials in different fields are different, it is necessary to debug the mix ratio of concrete materials in the laboratory to obtain concrete specimens with performance that meets the requirements.

[0003] After the concrete specimens are freshly mixed, they need to be placed in a specific environment for curing for a specified period of time, and then their performance is tested. The standard curing conditions for concrete specimens are a temperature range of 20℃±2℃, a relative humidity of not less than 95%, or curing in a non-flowing saturated calcium hydroxide solution at a temperature of 20℃±2℃. At present, most of the relevant units have concrete curing rooms, including refrigeration equipment, humidity control equipment, and several shelves for placing concrete specimens. However, the following problems may occur during the use of the curing room:

[0004] 1. In order to meet the simultaneous curing of a large number of concrete specimens, the curing room is generally large, so high-power refrigeration equipment and humidity control equipment are required. However, when the number of concrete specimens to be cured is small, it is easy to cause waste of resources and increase the curing cost. At the same time, since the refrigeration equipment and humidity control equipment are usually installed in the curing room, the high humidity environment increases the probability of damage to the refrigeration equipment and humidity control equipment. When one of the refrigeration equipment and humidity control equipment is damaged, the curing room will not work;

[0005] 2. The curing room uses tap water atomization spray to make the indoor humidity reach the target value, but atomization curing can easily cause the test personnel's vision to decrease in the curing room, greatly affecting the speed of taking or placing concrete specimens. When the concrete specimens are placed irregularly, it takes a long time to find the target specimens in the curing room;

[0006] 3. Only one curing condition can be set in the curing room. For concrete specimens that need to be cured under different curing conditions, it is necessary to purchase additional curing equipment or reset the curing conditions after the curing in the curing room is completed.

[0007] Chinese patent CN 217168993 U designs a modular curing mechanism and combined curing equipment. By placing the test block on a carrier and applying a curing cover to form a closed curing space, the large curing room is miniaturized, unitized, and modularized. The temperature and humidity in the curing space of the equipment are easy to adjust and maintain, and the temperature control is precise. At the same time, the modular curing mechanism can independently adjust the temperature and humidity in its curing space to meet different curing needs. Moreover, the equipment has an independent timing function, and different batches of concrete specimens are not easily confused when they are cured for different lengths of time. However, when curing concrete specimens, the equipment stacks the specimens together, while the specification requires that the specimens be spaced 10mm to 20mm apart during the curing process.

[0031] The technical solution of the present utility model is described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can better understand and implement the technical solution of the present utility model.

[0032] like Figure 1As shown, this embodiment is composed of 4 independent curing cabinets 1 and they are placed in a row, but in actual application, the number of curing cabinets 1 can be increased or decreased according to the actual situation, and the placement of the curing cabinets 1 can be reasonably arranged according to the spatial structure of the laboratory.

[0033] A control computer 4, i.e., a monitoring control terminal, is provided next to the curing cabinet 1. For easy operation, the computer 4 is placed on the work table 3. The computer 4 can be used as a control terminal of the curing cabinet 1. By setting the parameters of the temperature adjustment device 5 and the humidity adjustment device 6, the temperature and humidity inside each curing cabinet 1 can be adjusted. At the same time, the computer 4 also serves as a monitoring terminal of the curing cabinet 1. It is connected to the temperature and humidity sensor 8 to display the temperature and humidity conditions inside the curing cabinet 1 in real time. It can also be connected to a sensor for monitoring the number of test pieces to display the number of concrete test pieces in each drawer 2 inside each curing cabinet 1, providing a reference for the subsequent placement of concrete test pieces.

[0034] Figures 2 to 4 The internal structure of a drawer-type intelligent curing cabinet for concrete specimens of the utility model is shown. The curing cabinet 1 includes a temperature regulating device 5 for regulating the temperature inside the curing cabinet 1 and a humidity regulating device 6 for regulating the humidity inside the curing cabinet 1. The curing cabinet 1 is provided with a plurality of drawers 2 for placing concrete specimens. The drawers 2 and the cabinet body of the curing cabinet 1 form a closed curing space for the concrete specimens. The bottom of the drawer 2 has a grille hole. A spray head 11 is correspondingly provided above each drawer 2. Each spray head 11 is connected to the humidity regulating device 6 through a pipe 10. In this embodiment, the pipe 10 has a plurality of branches extending to the top of each drawer 2. The atomized water vapor generated by the humidity regulating device 6 flows to each spray head 11 through the pipe 10, and then sprays out through the spray head 11, so as to ensure that the humidity in each drawer 2 is the same. A temperature and humidity sensor 8 is provided inside the curing cabinet 1.

[0035] As a preferred embodiment:

[0036] The interior of the curing cabinet 1 is divided from top to bottom into an upper area, a middle area and a lower area that are interconnected. The upper area is a buffer area 13, the middle area is used to place each drawer 2, and the lower area is provided with a storage box 7. The buffer area 13 can prevent the uppermost drawer 2 from being too close to the temperature adjustment device 5, which may cause abnormal curing temperature and affect the curing result. The storage box 7 can hold water and debris falling from above.

[0037] In this embodiment, the temperature and humidity sensor 8 is arranged in the lower area, above the storage box 7. In other embodiments, a plurality of temperature and humidity sensors 8 can be arranged and distributed in different areas in the curing cabinet 1 to monitor the temperature and humidity in the curing cabinet. The monitoring data can be sent to the monitoring control terminal, i.e., the computer 4, through wired or wireless transmission to display the real-time temperature and humidity, and the temperature and humidity are adjusted to the required curing conditions through the temperature adjustment device 5 and the humidity adjustment device 6.

[0038] In this embodiment, a fan group consisting of a plurality of fans 12 is provided on the top wall of the curing cabinet 1. The air circulation in the curing cabinet 1 can be enhanced to make the temperature in the curing cabinet 1 uniform. Each drawer 2 is provided with a sensor for detecting concrete specimens. Preferably, the sensor for detecting concrete specimens is an infrared distance sensor 9 correspondingly installed above each drawer 2. When there is or is no concrete specimen inside the drawer 2, the detection result of the infrared distance sensor 9 is significantly different. When there is a concrete specimen inside the drawer 2, the detection result of the infrared distance sensor 9 is less than the detection result when there is no concrete specimen inside the drawer 2. The detection result is sent to the computer 4 through a wired or wireless transmission method, so that the number of concrete specimens inside the drawer 2 can be obtained without opening the drawer 2. Of course, in addition to using the infrared distance sensor 9 to detect whether there is a concrete specimen inside the drawer 2, other detection technologies can also be used to determine whether there is a concrete specimen inside the drawer 2. In this embodiment, the curing cabinet 1 has a uniform appearance. In order to better distinguish and quickly find the target concrete specimen, the curing cabinet 1 and the drawer 2 are numbered. Multiple concrete specimens can be placed inside each drawer 2. The concrete placement area inside the drawer 2 also needs to be numbered according to a certain rule and the information of the drawer 2 and the concrete specimen is stored in the monitoring and control terminal, which is used to record and display the number of concrete specimens in each drawer 2, the curing age of each specimen and other information.

[0039] In this embodiment, the temperature regulating device 5 is an air conditioner or a refrigerator. The humidity regulating device 6 is a humidifier. An industrial humidifier or other humidifier can be selected according to the maintenance conditions.

[0040] In this embodiment, the side wall of the curing cabinet 1 is filled with a thermal insulation layer in order to reduce heat loss in the curing cabinet.

[0041] The use of the utility model:

[0042] First, according to the curing conditions of the concrete specimens, including temperature conditions and humidity conditions, set the parameters of the temperature regulating device 5 and the humidity regulating device 6 in the computer 4, and turn on the fan 12; then, observe the temperature and humidity values ​​inside the curing cabinet 1 and the remaining position in the drawer 2 in the computer 4, and select the corresponding number of drawers 2 according to the number of concrete specimens that need to be cured. Preferably, all drawers 2 in a curing cabinet 1 should be filled with concrete specimens as much as possible before another curing cabinet 1 is enabled. At the same time, the same batch of concrete specimens should be placed in the same curing cabinet 1 as much as possible; then, when the curing conditions of the curing cabinet 1 meet the target requirements, open the selected drawers 2 in turn to place the concrete specimens, and then close the drawer 2. Finally, record the position number of the concrete specimen so that the target concrete specimen can be quickly found after the curing age is reached. It should be added that the storage box 7 needs to be checked regularly during use, and it should be cleaned when there is too much moisture or debris inside it.

[0043] The above implementation examples are only preferred implementation examples of the utility model, but cannot be used as limitations of the utility model.
