Description

Technical Field

[0001] This utility model relates to the field of temperature acquisition devices, specifically a pipeline temperature acquisition device. Background Technology

[0002] A temperature data logger is a device used to measure and record temperature. It is widely used in many fields. In order to monitor the actual heating status in heating pipes, it is necessary to monitor and collect the temperature of the medium in the pipes and transmit it back. This requires the use of a temperature data logger.

[0003] Existing pipeline temperature sensors are generally installed on pipelines using a threaded connection. This involves first drilling a threaded hole in the pipeline, then screwing the threaded end of the temperature sensor into the threaded hole to complete the installation. A sealing ring is also provided to improve the sealing performance of the temperature sensor after installation and prevent fluid leakage. However, since the sealing ring is generally annular, while the top of the pipeline is curved, the contact area between the sealing ring and the top of the pipeline is small, which affects the sealing effect. This may lead to fluid leakage in the pipeline and affect the performance of the temperature sensor. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a pipeline temperature acquisition device to solve the technical problem that the sealing effect is affected by the small contact area between the sealing ring and the top of the pipeline.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipeline temperature acquisition device, comprising a pipeline and a temperature sensor, wherein a threaded hole is provided at the top of the pipeline, a threaded head is installed on the outer wall of the temperature sensor, a connector is installed at the top of the threaded head, and a gasket is welded to the outer wall of the connector, an air storage cylinder is installed on one side of the top of the gasket, and a piston is provided inside the air storage cylinder, a threaded rod extending to the outside of the air storage cylinder is installed on the top of the piston through a bearing, an installation groove is provided at the bottom of the gasket, and a sealing airbag is installed inside the installation groove, and an air pipe is connected between the sealing airbag and the air storage cylinder.

[0006] By adopting the above technical solution, when the piston moves down, it will push the gas below the piston, so that the gas below the piston can enter the interior of the sealing airbag through the air pipe.

[0007] Furthermore, the threaded head is threaded into the inside of the threaded hole, and the bottom end of the temperature sensor is located inside the pipe.

[0008] By adopting the above technical solution, the temperature sensor can be installed after the threaded head is screwed into the threaded hole.

[0009] Furthermore, a knob is installed at the top of the threaded rod, and the outer wall of the knob is provided with anti-slip texture.

[0010] By adopting the above technical solution, it is convenient for workers to rotate the threaded rod by turning the knob, and thus move the threaded rod.

[0011] Furthermore, the outer wall of the piston is provided with a sealing ring, and the outer wall of the sealing ring is in contact with the inner wall of the gas storage cylinder.

[0012] By adopting the above technical solution, the sealing ring can improve the sealing between the gas storage cylinder and the piston, preventing the gas below the piston from flowing upward.

[0013] Furthermore, the bottom of the sealing airbag is in close contact with the top of the pipe.

[0014] By adopting the above technical solution, the sealing airbag can fit tightly against the top of the pipe, thereby improving the sealing between the temperature collector and the pipe and preventing fluid leakage from the pipe.

[0015] Furthermore, the outer wall of the piston is fitted to the inner wall of the gas storage cylinder, and the piston and the gas storage cylinder are slidably connected.

[0016] By adopting the above technical solution, the piston can slide inside the gas storage cylinder, thereby facilitating the adjustment of the piston's position.

[0017] Furthermore, the threaded rod is threadedly connected to the gas storage cylinder.

[0018] By adopting the above technical solution, the threaded rod can move when rotated, thus driving the piston to move.

[0019] Furthermore, the temperature sensor is detachably connected to the pipe via a threaded head.

[0020] By adopting the above technical solution, it is convenient to disassemble or install the temperature acquisition device.

[0021] Furthermore, an instrument panel is mounted on the top of the temperature sensor, and a glass cover is mounted on the outer surface of the instrument panel.

[0022] By adopting the above technical solution, the glass cover makes it easier for staff to read the temperature data on the instrument panel.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model is equipped with a sealing airbag, an air reservoir, an air pipe, a piston, and a threaded rod. When the threaded head is screwed into the threaded hole, the sealing airbag contacts the top of the pipe. At this time, the operator can rotate the threaded rod by turning the knob, so that the threaded rod moves down and drives the piston down. After the piston moves down, the air below the piston will enter the sealing airbag through the air pipe, so that the sealing airbag expands towards the pipe. Since the sealing airbag can be inflated to adjust its shape, it fits tightly against the curved surface of the pipe, increasing the contact area between the sealing airbag and the pipe, thereby improving the sealing between the temperature collector and the pipe and preventing the fluid inside the pipe from leaking due to gaps between the temperature collector and the pipe.

[0025] 2. This utility model has a sealing ring, which improves the sealing between the gas storage cylinder and the piston, preventing the gas below the piston from flowing upward, so as to ensure that the gas below the piston can only flow into the sealed airbag gasket through the gas pipe.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] A type of pipe temperature sensor, such as Figures 1-7 As shown, the device includes a pipe 1 and a temperature sensor 2. The top of the pipe 1 has a threaded hole 4. The outer wall of the temperature sensor 2 is fitted with a threaded head 5, and the top of the threaded head 5 is fitted with a connector 6. A gasket 16 is welded to the outer wall of the connector 6. An air reservoir 10 is fitted on one side of the top of the gasket 16. A piston 12 is installed inside the air reservoir 10. When the piston 12 moves down, it pushes the gas below the piston 12, allowing the gas below the piston 12 to enter the interior of the sealing airbag 8 through the air pipe 11. A threaded rod 13 extending to the outside of the air reservoir 10 is mounted on the top of the piston 12 through a bearing. The bottom of the gasket 16 has a mounting groove 9, and the sealing airbag 8 is installed inside the mounting groove 9. An air pipe 11 connects the sealing airbag 8 and the air reservoir 10.

[0038] See Figures 1-6 The outer wall of piston 12 is in contact with the inner wall of gas storage cylinder 10. Piston 12 is slidably connected to gas storage cylinder 10 so that piston 12 can slide inside gas storage cylinder 10, thereby facilitating adjustment of the position of piston 12. Threaded rod 13 is threadedly connected to gas storage cylinder 10 so that when threaded rod 13 is rotated, threaded rod 13 can move and drive piston 12 to move. The bottom of sealing gasket 8 is tightly in contact with the top of pipe 1. Sealing gasket 8 can be tightly in contact with the top of pipe 1, thereby improving the sealing between temperature collector and pipe 1 and preventing fluid leakage in pipe 1.

[0039] Specifically, the threaded head 5 is threaded into the inside of the threaded hole 4, and the bottom end of the temperature sensor 2 is located inside the pipe 1. After the threaded head 5 is screwed into the threaded hole 4, the installation of the temperature sensor can be completed. A knob 14 is installed at the top of the threaded rod 13. The outer wall of the knob 14 is provided with anti-slip texture, which makes it convenient for the operator to rotate the threaded rod 13 and move the threaded rod 13. An instrument panel 3 is installed at the top of the temperature sensor 2. A glass cover 7 is installed on the outer surface of the instrument panel 3. The glass cover 7 is set to make it convenient for the operator to read the temperature data on the instrument panel 3. The temperature sensor 2 is detachably connected to the pipe 1 through the threaded head 5, which facilitates the disassembly or installation of the temperature acquisition device.

[0040] Example 2:

[0041] Based on the above embodiment 1, in order to improve the sealing between piston 12 and gas storage cylinder 10 and prevent gas below piston 12 from flowing upward, the following structure will be provided.

[0042] See Figures 2-6 The outer wall of the piston 12 is provided with a sealing ring 15. The outer wall of the sealing ring 15 fits against the inner wall of the gas storage cylinder 10. The sealing ring 15 can improve the sealing between the gas storage cylinder 10 and the piston 12 and prevent the gas below the piston 12 from flowing upward.

[0043] The working principle of this utility model is as follows: First, the operator installs the temperature acquisition device on the pipe 1. The operator can screw the threaded head 5 on the temperature sensor 2 into the threaded hole 4. After the threaded head 5 is screwed into the threaded hole 4, the installation of the temperature acquisition device is completed. At this time, the bottom end of the temperature sensor 2 is located inside the pipe 1, and the sealing airbag 8 is in contact with the top of the pipe 1. Then, the operator can rotate the threaded rod 13 through the knob 14, so that the threaded rod 13 moves down and drives the piston 12 to move down. After the piston 12 moves down, the air below the piston 12 will enter the sealing airbag 8 through the air pipe 11, so that the sealing airbag 8 expands towards the pipe 1. Since the sealing airbag 8 can be adjusted in shape by inflation, it fits tightly against the arc surface of the pipe, thereby improving the sealing between the temperature acquisition device and the pipe 1 and preventing the fluid inside the pipe 1 from leaking. The temperature sensor 2 can measure the temperature of the fluid, and the glass cover 7 makes it convenient for the operator to read the temperature data on the instrument panel 3.
