[0033] A main control circuit board 4 and a power supply battery pack 32 are provided inside the monitoring box 3. The power supply battery pack 32 is used to power the device. The temperature sensor 5, the remote control antenna 6 and the alarm 7 are electrically connected through the main control circuit board 4.

The temperature sensor 5, the alarm 7 and the cooling fan 8 are all connected to the external mobile terminal electrical signal through the remote control antenna 6. The outer end of the central pipe 2 is threaded and connected to a breathable closed cover 10.

[0034] Furthermore, the main pipe 1 and the center pipe 2 are both cylindrical structure pipes. The outer wall of the main pipe 1 is provided with a buffer rubber pad 13. After the main pipe 1 is inserted into the opened hole, the buffer rubber pad 13 plays a preliminary pressure-resistant effect. The inner end of the main pipe 1 is a closed structure. The outer ring of the main pipe 1 away from the closed end is provided with a connecting plate 14. The connecting plate 14 is provided with a number of connecting holes 15. A hole of corresponding size is opened on the bridge pier using a punching machine, and then the device is inserted into the hole. The outer wall of the main pipe 1 is tightly fitted with the inner wall of the hole, and the inner wall of the connecting plate 14 is fitted with the surface of the bridge pier. Then, holes are punched according to the positions of the several connecting holes 15 opened on the connecting plate 14, and then expansion screws are inserted into the connecting holes 15 and inside the punched holes to fix the device.

[0035] Furthermore, a number of first reinforcing support rods 9 are evenly distributed between the inner wall of the main pipe 1 and the outer wall of the center pipe 2. Reinforcing support plates 11 are provided at both ends of the first reinforcing support rods 9 connected to the inner wall of the main pipe 1 and the outer wall of the center pipe 2. The settings of the first reinforcing support rods 9 and the reinforcing support plates 11 can improve the pressure resistance effect and prevent the internal center pipe 2 from deformation. The contact surfaces of the two reinforcing support plates 11 with the inner wall of the main pipe 1 and the outer wall of the center pipe 2 are provided with rubber shock-absorbing pads 12.

The diameter of the first cover 25 is smaller than the diameter of the second cover 26. The outer ring of the first cover 25 is provided with an external thread structure 27. The breathable closed cover 10 is screwed and connected to the central pipe 2 using the external thread structure 27 and the internal thread structure 24, thereby achieving the closure of the central pipe 2. The inner surface of the second cover 26 protruding from the first cover 25 is affixed with a rubber sealing gasket 28. The rubber sealing gasket 28 improves the sealing effect and prevents rainwater and dust from entering the interior of the central pipe 2. A rotating handle 29 is provided on the outer side of the first cover 25. The rotating handle 29 facilitates the rotation of the breathable closed cover 10.

[0039] Furthermore, a plurality of heat exhaust holes 30 are provided on the breathable closed cover 10, and a plurality of second heat exhaust holes 31 are provided at one end of the monitoring box 3 away from the cooling fan 8.

[0040] A method for monitoring the temperature of a large-volume concrete in a bridge pier based on remote sensing comprises the following steps:

[0041] S1: Device installation: Use a punch to drill holes of corresponding sizes on the bridge pier, then insert the device into the hole, with the outer wall of the main pipe 1 tightly fitting with the inner wall of the hole, and the inner wall of the connecting plate 14 fitting with the surface of the bridge pier. Then, drill holes according to the positions of the several connecting holes 15 opened on the connecting plate 14, and then use expansion screws to insert into the connecting holes 15 and the inside of the drilled holes to fix the device;

[0042] S2: Monitoring box installation: After the main pipe 1 is installed and fixed, the monitoring box 3 is pushed into the center pipe 2 through the slide 18 and the slider 17. Then, the breathable sealing cover 10 is screwed and connected to the center pipe 2 using the external thread structure 27 and the internal thread structure 24, thereby sealing the center pipe 2.

[0043] S3: Temperature monitoring: When the device is fully installed, turn on the device, and the temperature sensor 5 starts normal sensing work. When the sensed temperature is too high, the alarm 7 starts to alarm, and the external mobile terminal receives the alarm signal and displays the temperature. Then, the alarm 7 is controlled to be turned off by remote control in conjunction with the remote control antenna 6, and the staff is notified to take corresponding measures. At the same time, the cooling fan 8 is controlled to turn on to dissipate the high temperature inside the central pipe 2.

[0044] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0045] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0046] The foregoing description shows and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art.
