Description

Technical Field

[0001] This application relates to the field of temperature measuring instruments, and more specifically, to a concrete temperature measuring instrument for concrete. Background Technology

[0002] A concrete thermometer is a specialized device used to monitor changes in concrete temperature in real time. It is widely used in construction engineering and is an indispensable quality control tool in modern construction projects.

[0003] The prior art publication (announcement) document CN215984904U provides a concrete temperature measuring instrument for concrete. In the related technology of this device, the setting of a conical detection head, a second support rod, a detection sensor assembly, a connecting pipe and a threaded pipe is conducive to the use of the device. The threaded connection of the connecting pipe and the threaded pipe facilitates the disassembly of the conical detection head and the disassembly and maintenance of the detection sensor assembly during use.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following drawbacks: the temperature measuring instrument structure is not convenient enough and has poor flexibility when used for testing shallow concrete such as floor slabs.

[0005] In view of this, we propose a concrete temperature measuring instrument for concrete. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a concrete temperature measuring instrument for concrete.

[0007] The concrete temperature measuring instrument for concrete provided in this application adopts the following technical solution:

[0008] A concrete temperature measuring instrument for concrete includes an extension cylinder. One end of the extension cylinder is fixedly connected to a power supply and display mechanism, and the other end is fixedly connected to a temperature measuring head. A protective cylinder is slidably connected to the outside of the extension cylinder. One end of the protective cylinder is fixedly connected to an expansion plate, and the other end is fixedly connected to a compressed air cylinder. The compressed air cylinder is sleeved on the outside of the extension cylinder and can abut against and limit the power supply and display mechanism. A three-way control valve is fixedly connected to the one-way air inlet end of the compressed air cylinder. One end of the three-way control valve is fixedly connected to an exhaust pipe, and the other end of the exhaust pipe extends into the interior of the expansion plate and is clearance-fitted with the temperature measuring head.

[0009] By adopting the above technical solution, the extended cylinder with the installed power supply display mechanism and temperature detection head is protected by the protective cylinder, thus achieving the safety protection of the temperature measurement structure. After the extended cylinder is extended and adjusted, the temperature detection head can be used to flexibly measure the temperature of shallow concrete slurry, improving the convenience of the device. When the extended cylinder is extended and adjusted, the compressed air cylinder can be squeezed to release gas, and the gas can be blown through the exhaust pipe to clean the outside of the extended cylinder, ensuring the cleanliness of the extended cylinder when stored and used.

[0010] As an optional solution to the technical solution of this application, a limiting ring is fixedly connected to one side of the expansion plate by bolts. A brush ring is rotatably engaged between the limiting ring and the expansion plate. The brush ring has an annular meshing tooth groove on its outer side. A drive gear shaft is meshed and adapted to one side of the meshing tooth groove. The drive gear shaft is rotatably connected inside the expansion plate and connected to a drive motor. The drive motor is fixedly connected to one side of the expansion plate and electrically connected to the power supply and display mechanism.

[0011] By adopting the above technical solution, the brush ring can be driven to rotate by the drive motor, thereby cleaning the surface of the stored temperature measuring head and improving the aesthetics of the temperature measuring structure.

[0012] As an optional solution to the technical solution of this application, the brush ring has an outer groove, and a plurality of through holes are formed on one side of the groove.

[0013] By adopting the above technical solution and utilizing the interconnected structure of the through hole and the ring groove, the brush ring can be cleaned with water according to usage needs, thereby improving the brush ring's performance.

[0014] As an optional solution to the technical solution of this application, the inner wall of the expansion plate is provided with a groove, and multiple connecting pipes are fixedly connected to the outside of the groove. A water storage ring is fixedly connected between the multiple connecting pipes. The water storage ring is fixedly connected to the outside of the protective cylinder, and one side of the water storage ring is fixedly connected to the other end of the three-way control valve through a hose.

[0015] By adopting the above technical solution and using the opening and closing regulation of the three-way control valve, the gas inside the compressed air cylinder can be pressurized and filled into the water storage cylinder ring. This causes the water inside the water storage cylinder ring to flow into the groove and be sprayed out through the brush ring. This allows the rotating brush ring to spray water to clean the extension cylinder and temperature detection head, improving the aesthetics of the device's storage and cleaning.

[0016] As an optional solution to the technical solution in this application, both the water storage ring and the protective cylinder are transparent structures made of organic plastic.

[0017] By adopting the above technical solution, the transparent water storage ring and protective cylinder made of organic plastic can be used to facilitate the observation of the cleanliness of the extension cylinder.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application achieves the safety protection of the temperature measuring structure by using an extension cylinder with a power supply display mechanism and a temperature measuring head installed under the protection of a protective cylinder. After the extension cylinder is extended and adjusted, the temperature measuring head can be used to flexibly measure the temperature of shallow concrete slurry, improving the convenience of the device. When the extension cylinder is extended and adjusted, the compressed air cylinder can be squeezed to release gas, and the gas can be blown through the exhaust pipe to clean the outside of the extension cylinder, ensuring the cleanliness of the extension cylinder when stored and used.

[0020] 2. This application utilizes a drive motor to rotate the brush ring, thereby cleaning the surface of the stored temperature measuring head and improving the aesthetics of the temperature measuring structure. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1-5 The concrete temperature measuring instrument for concrete described in this application includes an extension cylinder 1. One end of the extension cylinder 1 is fixedly connected to a power supply display mechanism 2, and the other end is fixedly connected to a temperature measuring head 3. A protective cylinder 4 is slidably connected to the outside of the extension cylinder 1. One end of the protective cylinder 4 is fixedly connected to an expansion plate 5, and the other end is fixedly connected to a compressed air cylinder 6. The compressed air cylinder 6 is sleeved on the outside of the extension cylinder 1 and can abut against and limit the power supply display mechanism 2. A three-way control valve 7 is fixedly connected to the one-way air inlet end of the compressed air cylinder 6. One end of the three-way control valve 7 is fixedly connected to an exhaust pipe 8, and the other end of the exhaust pipe 8 extends into the interior of the expansion plate 5 and is clearance-fitted with the temperature measuring head 3.

[0029] This concrete temperature measuring instrument utilizes an extension cylinder 1 equipped with a power supply display mechanism 2 and a temperature measuring head 3, protected by a protective cylinder 4, to ensure the safety of the temperature measuring structure. After the extension cylinder 1 is extended and adjusted, it drives the temperature measuring head 3 to flexibly measure the temperature of shallow concrete slurry, improving the ease of use of the device. Furthermore, when the extension cylinder 1 is extended and adjusted, it can compress the air cylinder 6 to release gas, which can then be blown through the exhaust pipe 8 to clean the exterior of the extension cylinder 1, ensuring the cleanliness of the extension cylinder 1 during storage and use.

[0030] Reference Figure 4 and Figure 5 In the concrete temperature measuring instrument for concrete described in this application embodiment, a limiting ring 51 is fixedly connected to one side of the expansion plate 5 by bolts. A brush ring 52 is rotatably engaged between the limiting ring 51 and the expansion plate 5. The brush ring 52 has a ring-shaped meshing tooth groove on its outer side. A drive gear shaft 53 is meshing and driven on one side of the meshing tooth groove. The drive gear shaft 53 is rotatably connected inside the expansion plate 5 and is connected to a drive motor 54. The drive motor 54 is fixedly connected to one side of the expansion plate 5 and is electrically connected to the power supply and display mechanism 2. The brush ring 52 has an annular groove 55 on its outer side, and multiple through holes are opened on one side of the annular groove 55.

[0031] This concrete temperature measuring instrument uses a drive motor 54 to drive the brush ring 52 to rotate, thereby cleaning the surface of the temperature measuring head 3 and improving the aesthetics of the temperature measuring structure. The connection between the through hole and the ring groove 55 allows the brush ring 52 to be cleaned with water as needed, improving the performance of the brush ring 52.

[0032] Reference Figure 4 and Figure 2In the concrete temperature measuring instrument for concrete described in this application embodiment, a groove 56 is provided on the inner wall of the expansion plate 5. Multiple connecting pipes 57 are fixedly connected to the outside of the groove 56. A water storage ring 58 is fixedly connected between the multiple connecting pipes 57. The water storage ring 58 is fixedly connected to the outside of the protective cylinder 4, and one side of the water storage ring 58 is fixedly connected to the other end of the three-way control valve 7 through a hose.

[0033] This concrete temperature measuring instrument for concrete, by using the opening and closing of the three-way control valve 7, allows the gas inside the compressed air cylinder 6 to be filled into the water storage ring 58 for pressurization, causing the water inside the water storage ring 58 to flow into the groove 56 and be sprayed out through the brush ring 52. This enables the rotating brush ring 52 to spray water to clean the extension cylinder 1 and the temperature measuring head 3, improving the aesthetics of the device's storage and cleaning.

[0034] Reference Figure 2 In the concrete thermometer for concrete described in this application, both the water storage ring 58 and the protective cylinder 4 are transparent structures made of organic plastic.

[0035] This concrete temperature measuring instrument for concrete allows for easy observation of the cleanliness of the extended cylinder 1 by utilizing a transparent water storage ring 58 and a protective cylinder 4 made of organic plastic.

[0036] Working principle: When using this temperature measuring device to measure the temperature of shallow concrete slurry, the operator closes the three-way control valve 7 port connected to the water storage cylinder ring 58 and opens the three-way control valve 7 port connected to the exhaust pipe 8.

[0037] Next, attach the expansion plate 5 to the surface of the concrete slurry, and push down the extension cylinder 1 to drive the temperature detection head 3 to insert into the shallow layer of concrete slurry for temperature detection.

[0038] When it is necessary to clean the slurry of the temperature detection head 3, the operator opens the three-way control valve 7 port connected to the water storage ring 58 and closes the three-way control valve 7 port connected to the exhaust pipe 8.

[0039] Then, the extension cylinder 1 is pushed to compress the air cylinder 6. The gas inside the air cylinder 6 flows into the water storage ring 58. Under pressure, the water in the water storage ring 58 is filled into the groove 56 and flows through the through hole of the brush ring 52 and sprays out. The brush ring 52 is driven by the drive gear shaft 53 at the output end of the drive motor 54 to rotate and spray water to clean the extension cylinder 1 and the temperature detection head 3.
