The embodiments described by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0034] The following will be combined with Figures 1 to 4 to describe the microwave oven 1000 for curing concrete according to the embodiments of the present invention.

[0035] As Figures 1 to 4, the microwave oven 1000 for curing concrete according to an embodiment of the present invention includes a microwave oven body 1, a microwave emitter 2, a first temperature sensor 3, a second temperature sensor 4, and a power and time controller 5. Among them, the microwave oven body 1 includes a box body 101 and a box door 102. The box body 101 is provided with a box opening, and the box door 102 is installed on the box body 101 to open or close the box opening; the microwave emitter 2 is installed on the microwave oven body 1 for heating the concrete specimen 6 placed in the microwave oven body 1; the first temperature sensor 3 is used to detect the internal temperature of the concrete specimen 6; the second temperature sensor 4 is used to detect the surface temperature of the concrete specimen 6; the power and time controller 5 is respectively connected to the microwave emitter 2, the first temperature sensor ③ and the second temperature sensor 4, and is used to receive the detected temperatures of the first temperature sensor 3 and the second temperature sensor 4 in real time, and control the emission power and emission time of the microwave emitter 2 in real time according to the detected temperatures of the first temperature sensor 3 and the second temperature sensor 4, so that the internal temperature of the concrete specimen 6 is within the set temperature range.

[0036] Specifically, the microwave oven body 1 includes a box body 101 and a box door 102. The box body 101 is provided with a box opening, and the box door 102 is installed on the box body 101 to open or close the box opening. By providing the box opening on the box body 101, it is convenient to put in and take out the concrete specimen 6. By providing the box door 102, it is beneficial for the box door 102 and the box body 101 to form a closed space for microwave heating, and up to four concrete specimens 6 can be accommodated in this closed space.

[0037] The microwave emitter 2 is installed on the microwave oven body 1 for heating the concrete specimen 6 placed in the microwave oven body 1. Specifically, the microwave emitter 2 can heat the concrete specimen 6 in the microwave oven body 1 by emitting microwaves, and the heating speed is fast, so that the microwave oven can improve the early strength of the concrete specimen 6 in a short time.

[0038] The first temperature sensor 3 is used to detect the internal temperature of the concrete specimen 6; the second temperature sensor 4 is used to detect the surface temperature of the concrete specimen 6. Thus, the detection of the internal temperature and the surface temperature of the concrete specimen 6 can be realized, and it can be known whether the temperature difference between the inside and the surface of the concrete specimen 6 is too large and whether the internal temperature of the concrete specimen 6 is within the set temperature range.

[0039] The power and time controller 5 is respectively connected to the microwave transmitter 2, the first temperature sensor 3 and the second temperature sensor 4, and is used to receive in real time the detected temperatures of the first temperature sensor 3 and the second temperature sensor 4, and control in real time the transmission power of the microwave transmitter 2 according to the detected temperatures of the first temperature sensor 3 and the second temperature sensor 4, so as to control in real time the heating temperature and heating time of the microwave oven, so that the internal temperature of the concrete specimen 6 is within the set temperature range. It can be understood that when the temperature difference between the inside and the surface of the concrete specimen 6 is too large or the internal temperature of the concrete specimen 6 is not within the set temperature range, the power and time controller 5 can control the increase or decrease of the microwave transmission power and the transmission time of the microwave transmitter 2, so that the temperature of the concrete specimen 6 is within the set temperature range again, and the concrete specimen 6 can quickly reach the early target strength.

[0040] For the microwave oven 1000 for curing concrete according to an embodiment of the present invention, the working process is as follows: the concrete specimen 6 is placed into the microwave oven cavity 101 from the box opening, the first temperature sensor 3 is inserted into the interior of the concrete specimen 6, and the box door 102 is closed; the microwave oven 1000 for curing concrete is started, the microwave transmitter 2 heats the concrete specimen 6 placed in the microwave oven cavity 101, the first temperature sensor 3 detects in real time the internal temperature of the concrete specimen 6, the second temperature sensor 4 detects in real time the surface temperature of the concrete specimen 6, and the power and time controller 5 adjusts in real time the microwave transmission power and the transmission time of the microwave transmitter 2 by receiving the detected temperatures of the first temperature sensor 3 and the second temperature sensor 4, so as to control in real time the heating temperature and heating time of the microwave oven, and ensure that the temperature of the concrete specimen 6 is within the set temperature range, so that the concrete specimen 6 quickly reaches the early target strength under suitable temperature conditions.

[0041] For the microwave oven 1000 for curing concrete according to an embodiment of the present invention, during the concrete curing process, the internal temperature and the surface temperature of the concrete specimen 6 are detected in real time by the first temperature sensor 3 and the second temperature sensor 4, and at the same time, the power and time controller 5 is used to control the transmission power and the transmission time of the microwave transmitter 2, so as to control in real time the heating temperature and heating time of the microwave oven, so as to ensure that the internal temperature of the concrete specimen 6 is always within the set temperature range, and the concrete specimen 6 reaches the early target strength in a short time. In summary, the microwave oven 1000 for curing concrete according to an embodiment of the present invention can control the microwave heating time and heating temperature in real time, and has high efficiency.

[0042] According to an embodiment of the present invention, there are four microwave transmitters 2, which are respectively installed on the left inner wall, the rear inner wall, the right inner wall of the box body 101, and the inner wall of the box door 102. It can be understood that multiple microwave transmitters 2 heat the concrete specimen 6 from four different directions, so that the concrete specimen 6 is heated evenly, the early target strength of the concrete specimen 6 can be enhanced in a relatively short time, the curing time is reduced, and the curing efficiency is improved.

[0043] According to an embodiment of the present invention, the first temperature sensor 3 is an externally inserted contact type temperature sensor. An insertion hole 7 is provided on the top wall of the box body 101, and the insertion hole 7 just faces the center of the upper surface of the concrete specimen 6.

It can be understood that the aperture of the insertion hole 7 provided on the top wall of the box body 101 can be set according to the diameter of the first temperature sensor 3. The newly placed concrete specimen 6 in the microwave oven body 1 is still in a soft and wet state, and the first temperature sensor 3 can be directly inserted into the interior of the new concrete specimen 6 through the insertion hole 7.

[0044] According to some embodiments of the present invention, the second temperature sensor 4 is an infrared sensor, and the second temperature sensor 4 is installed on the inner wall of the box body 101 or the inner wall of the box door 102. During the curing process, the infrared sensor uses infrared rays to measure the temperature inside the box body 101 or the box door 102.

It can be understood that one end of the first temperature sensor 3 is inserted into the concrete specimen 6, and the other end is connected to the wire 11, and the wire 11 is connected to the first display screen 8. Thus, the first display screen 8 can display the internal temperature of the concrete specimen 6 in real time; the second temperature sensor 4 is installed on the inner side wall of the box body 101 or the inner side wall of the box door 102, one end is connected to a wire, and the wire is connected to the second display screen 9. Thus, the second display screen 9 can display the surface temperature of the concrete specimen 6 in real time; the power and time controller 5 is connected to the third display screen 10 through a wire. Thus, the third display screen 10 can display the microwave emission power and emission time in real time.

[0048] According to an embodiment of the present invention, it further includes a cushion block 12 on which the concrete specimen 6 can be placed, and the cushion block 12 is detachably arranged on the inner bottom wall of the box body 101. It can be understood that the cushion block 12 is separable from the microwave oven box body 101, which is convenient for placing the concrete specimen 6 on the cushion block 12 and then putting it into the microwave oven box body 101 or taking it out of the box body 101.

Thus, by supporting the concrete specimen 6 with the support members 13, a gap can be left between the concrete specimen 6 and the cushion block 12, which is convenient for air circulation and prevents the concrete specimen 6 from exploding during the heating process.

[0050] According to a still further embodiment of the present invention, the support member 13 is in a long strip shape. It can be understood that the support member 13 is used to support the concrete specimen 6, and it can also be in other shapes besides the long strip shape.
