Description

Technical Field

[0001] This utility model relates to the field of concrete temperature measurement technology, specifically a temperature measuring device that facilitates the recovery of temperature probes. Background Technology

[0002] When pouring large volumes of concrete during the hot season, the ambient temperature will increase significantly due to the heat from solar radiation. The combination of high external temperatures and the heat released from the hydration of concrete will cause the internal temperature of the concrete to rise sharply. Since concrete has poor thermal conductivity, the internal heat is difficult to dissipate quickly, easily creating a significant temperature difference between the inside and outside.

[0003] When the temperature difference exceeds the allowable value specified in the code, compressive stress is generated inside the concrete and tensile stress is generated on the surface. If the tensile stress exceeds the tensile strength of the concrete, it will directly cause cracking, seriously affecting the integrity, durability, and load-bearing capacity of the large-volume concrete structure. Therefore, effectively controlling the ambient temperature of the pouring chamber and the temperature difference between the inside and outside of the concrete is the core key to avoiding concrete cracking and ensuring project quality when pouring large-volume concrete during the high-temperature season. Currently, natural ventilation cooling, misting cooling, and simple sunshade coverings are commonly used to reduce the ambient temperature of the pouring chamber and control the temperature rise of the concrete during high-temperature concrete pouring.

[0004] During the spray cooling process, multiple temperature sensors arranged at discrete points are needed to measure the temperature inside the concrete layer. However, in existing temperature measuring devices, the temperature probes are fixed together after the concrete has hardened, making it impossible to remove them properly. The only solution is to cut off the temperature probes, which is a waste of the temperature sensor probes. Utility Model Content

[0005] The present invention aims to solve the problem that it is inconvenient to remove the thermocouple temperature probes embedded in the concrete after it has cured.

[0006] This utility model is achieved through the following technical solution: A temperature measuring device for easy retrieval of a temperature probe includes a temperature sensor electrically connected to a temperature transmitter via a cable. The temperature transmitter is fixedly connected to and mounted in a housing, and the temperature transmitter is wirelessly connected to a temperature receiver. The temperature sensor slides against the inner wall of the contact sleeve, and the sleeve is fixedly connected to the head. Apply a layer of lubricant between the temperature sensor and the housing. Multiple first magnetic strips are provided on the edges of the four side walls at one end of the box opening; the box body is magnetically attached to the box lid.

[0007] The lid opening has multiple second magnetic strips on the edges of the four side walls.

[0008] Each of the first magnetic strips adheres to and attracts each of the second magnetic strips.

[0009] The temperature sensor slides and fits against the inner wall of the contact sleeve.

[0010] The sleeve has vents on its transverse open sidewall. The vents penetrate the sidewalls of the sleeve and the head in sequence, and the bottom of the vents penetrates and connects to the interior of the head.

[0011] Multiple straps are fixedly connected to one side of the outer wall of the box.

[0012] The outer wall of one side of the box has a connecting port for installing cables, and the gap between the connecting port side wall and the cable hole is sealed with sealant.

[0013] The sleeve is made of copper.

[0014] The sleeve is made of polytetrafluoroethylene.

[0015] The lubricating layer is made of silicone-based grease.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows for easy removal of the temperature sensor after concrete temperature measurement. Air is introduced through a vent into the bottom of the sleeve, preventing the sensor from being attracted by negative pressure. The sensor can then be directly removed after measurement, enabling sensor retrieval. Furthermore, the sleeve protects the temperature probe from damage during concrete vibration, ensuring smooth temperature monitoring. The equipment used in this temperature measurement device is common and readily available in construction, facilitating on-site implementation. Most components, including the temperature sensor probe, can be reused according to construction needs, improving construction efficiency and reducing costs. Attached Figure Description
