Description

Technical Field

[0001] This utility model relates to the field of intelligent water temperature detection technology for pressure pipelines, specifically to an intelligent temperature measuring device for pressure pipelines. Background Technology

[0002] To ensure the safety and operational stability of pressure pipelines, hydrostatic testing is necessary. Accurate measurement of the water temperature inside the pipeline is crucial during this test. Changes in water temperature not only affect the accuracy of the test results but may also impact the pipeline's actual pressure-bearing capacity. Therefore, real-time monitoring of the water temperature at different points within the pipeline has significant engineering implications.

[0003] Currently, most traditional pressure pipeline water temperature measurement equipment is fixedly installed. While it can achieve basic temperature monitoring, the installation location of traditional temperature measuring devices is limited in long-distance, large-diameter steel pipelines, making it impossible to comprehensively and accurately reflect the real-time water temperature at various locations within the pipeline. Furthermore, during hydrostatic testing, traditional equipment struggles to withstand the high pressure and complex fluid environment inside the pipeline, increasing the risk of equipment failure and affecting the accuracy of the measurement results.

[0004] In summary, there is an urgent need for an intelligent temperature measurement device for pressure pipelines to solve or at least partially solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent temperature measuring device for pressure pipelines, aiming to solve the problems of existing temperature measuring devices being unable to move and having limited temperature measurement capabilities. The specific technical solution is as follows:

[0006] A smart temperature measuring device for pressure pipelines includes a temperature measuring head, a wire, and a receiving mechanism. The temperature measuring head is disposed inside the pressure pipeline, and the receiving mechanism is disposed outside the pressure pipeline. The pressure pipeline is provided with a through hole and a sealing element. The first end of the wire is connected to the temperature measuring head, and the second end of the wire passes through the through hole and is connected to the receiving mechanism. The sealing element is disposed at the through hole to seal the through hole. The density of the temperature measuring head is equal to the density of the wire and the density of the liquid in the pressure pipeline. The temperature measuring head includes a mounting base, a temperature sensor, and a driving assembly. The driving assembly and the temperature sensor are both mounted on the mounting base, and the wire is connected to the temperature sensor.

[0007] Furthermore, the drive assembly includes an electric motor and a propeller. The electric motor is mounted on a mounting base, and the propeller is mounted on the output end of the electric motor. The wires are arranged in two strands, one of which is a signal wire and the other is a control wire. The first end of the signal wire is connected to a temperature sensor, and the second end of the signal wire is connected to a receiving mechanism. The first end of the control wire is connected to the electric motor, and the second end of the control wire is connected to the receiving mechanism. The wires also include an insulating sheath, which wraps around the signal wire and the control wire. The end of the insulating sheath closest to the temperature sensor is connected to the mounting base.

[0008] Furthermore, the sealing element includes a sleeve and a pressure-bearing nut. The sleeve is arranged inside the through hole and extends through the through hole. The pressure-bearing nut is threadedly connected to the end of the sleeve located outside the pressure pipe. The conductor passes through the pressure-bearing nut and is sealed to the pressure-bearing nut.

[0009] Furthermore, the pressure-bearing nut is provided with a through hole, and an annular rubber gasket is placed inside the through hole. The wire passes through the through hole and is arranged with the outer wall of the wire and the annular rubber gasket in an interference fit.

[0010] Furthermore, it also includes a pressure gauge, which is installed on the pressure pipeline.

[0011] Furthermore, it also includes an exhaust valve, which is installed on the pressure pipeline and positioned at the top of the pressure pipeline.

[0013] Furthermore, the switch includes three positions: forward rotation, stop, and reverse rotation.

[0014] The application of the technical solution of this utility model has the following beneficial effects:

[0015] By driving the temperature sensor to move within the liquid being measured using a drive assembly, temperature can be measured at any point within the pressure pipeline, facilitating temperature measurement at various locations throughout the pipeline. During movement, the temperature sensor measures the liquid temperature and converts the temperature signal into an electrical signal, which is then transmitted to the receiving mechanism via wires.

[0022] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0024] Example:

[0025] See Figures 1-3This embodiment provides an intelligent temperature measuring device for a pressure pipeline, including a temperature measuring head 1, a wire 2, and a receiving mechanism 3. The temperature measuring head 1 is disposed inside the pressure pipeline 4, and the receiving mechanism 3 is disposed outside the pressure pipeline 4. The pressure pipeline 4 is provided with a through hole and a sealing element 5. The first end of the wire 2 is connected to the temperature measuring head 1, and the second end of the wire 2 passes through the through hole and is connected to the receiving mechanism 3. The sealing element 5 is disposed at the through hole to seal the through hole. The density of the temperature measuring head 1 is equal to the density of the wire 2 and the density of the liquid in the pressure pipeline 4. The temperature measuring head 1 includes a mounting base 11, a temperature sensor 12, and a driving assembly 13. The driving assembly 13 and the temperature sensor 12 are both mounted on the mounting base 11, and the wire 2 is connected to the temperature sensor 12.

[0026] Specifically, the temperature measuring head 1 is made to have the same density as the liquid in the pressure pipe 4, that is, after the temperature measuring head 1 is placed in the pressure pipe 4, the temperature measuring head 1 can be suspended in the liquid being measured.

[0027] It is understood that by driving the temperature measuring head 1 to move in the liquid being measured through the driving component 13, the temperature can be measured at any point in the pressure pipeline 4, facilitating the measurement of the temperature at various points in the pressure pipeline 4. During the movement, the temperature sensor 12 measures the liquid temperature and converts the temperature signal into an electrical signal, which is then sent to the receiving mechanism 3 via the wire 2. The operator reads the temperature parameters through the receiving mechanism 3. With the above-mentioned device, the temperature at various points in the pressure pipeline 4 can be conveniently measured, solving the problem of the one-sidedness of temperature measurement by fixed temperature measuring devices in large-diameter and long pressure pipelines 4. This device can conveniently measure any point in large-diameter and long pipelines, and by measuring the temperature at multiple points, it can reflect the temperature situation at various points in large-diameter and long pressure pipelines 4. (It should be noted that large-diameter pipelines here refer to pressure pipelines 4 with an inner diameter exceeding 20 cm and a length exceeding 10 m. It should also be noted that when the liquid flow velocity in the pipeline is slow, the temperature at the upstream end and the downstream end of the pipeline is inconsistent.)

[0028] Furthermore, the drive assembly 13 includes an electric motor 131 and a propeller 132. The electric motor 131 is mounted on the mounting base 11, and the propeller 132 is mounted on the output end of the electric motor 131. The wire 2 has two strands, one of which is a signal wire and the other is a control wire. The first end of the signal wire is connected to the temperature sensor 12, and the second end of the signal wire is connected to the receiving mechanism 3. The first end of the control wire is connected to the electric motor 131, and the second end of the control wire is connected to the receiving mechanism 3. The wire 2 also includes an insulating sheath, which wraps around the signal wire and the control wire. The end of the insulating sheath near the temperature sensor 12 is connected to the mounting base 11.

[0029] It is understood that the propeller 132 is driven to rotate by the electric motor 131, which in turn moves the mounting base 11 and temperature sensor 12 on the temperature measuring head 1. After moving to the required position, the temperature sensor 12 measures the liquid temperature and converts the temperature signal into an electrical signal, which is then transmitted to the receiving mechanism 3 via a signal line. The operator reads the liquid temperature in the pressure pipe 4 through the receiving mechanism 3. It should be noted that the overall density of the conductor 2 is equal to the density of the liquid in the pressure pipe 4. In actual production, the center of both the signal line and the control line is made of metal, mainly copper wire. Since the density of copper is generally higher than that of the liquid in the pipe, the insulation is made of a material with a lower density than that of the liquid in the pressure pipe 4. Ultimately, this makes the overall density of the conductor 2 basically equal to the density of the liquid, allowing the conductor 2 to float in the liquid in the pressure pipe 4.

[0030] Furthermore, the sealing element 5 includes a sleeve 51 and a pressure-bearing nut 52. The sleeve 51 is arranged in the through hole and extends through the through hole. The pressure-bearing nut 52 is threaded to the end of the sleeve 51 located outside the pressure pipe 4. The wire 2 passes through the pressure-bearing nut 52 and is sealed to the pressure-bearing nut 52.

[0031] It can be seen that, through the above-mentioned setup, the wire 2 can be smoothly connected to the inside and outside of the pressure pipe 4 while keeping the pressure pipe 4 sealed.

[0032] Furthermore, the pressure nut 52 is provided with a through hole, and an annular rubber gasket is provided inside the through hole. The wire 2 is arranged through the through hole, and the outer wall of the wire 2 is arranged with an interference fit with the annular rubber gasket.

[0033] It is known that the annular rubber gasket is used to prevent liquid leakage between the pressure nut 52 and the wire 2.

[0034] Furthermore, it also includes a pressure gauge 6, which is installed on the pressure pipe 4.

[0035] It is known that the pressure in the pressure pipeline 4 is measured and displayed in real time by the pressure gauge 6, and the operator can read the pressure in the pressure pipeline 4 through the pressure gauge 6 and take corresponding actions.

[0036] Furthermore, it also includes an exhaust valve 7, which is installed on the pressure pipe 4 and is located at the top of the pressure pipe 4.

[0037] It is known that when there are gas impurities in the pipeline, the gas in the pressure pipeline 4 can be discharged through the exhaust valve 7.

[0038] Furthermore, the receiving mechanism 3 includes a display screen 31, a battery 32, and a switch 33. The end of the signal line away from the temperature sensor 12 is connected to the display screen 31 to display the temperature. The battery 32 is used to power both the display screen 31 and the electric motor 131. The first end of the switch 33 is connected to the battery 32, and the second end of the switch 33 is connected to the electric motor 131.

[0039] It is known that the battery 32 supplies power to the display screen 31 and the electric motor 131, the display screen 31 displays the temperature measured by the temperature sensor 12, and the switch 33 can control the start and stop of the electric motor 131.

[0040] Furthermore, switch 33 includes three positions: forward rotation, stop, and reverse rotation.

[0041] It is known that by setting three gears, the electric motor 131 can rotate in the forward direction, rotate in the reverse direction, and stop, thereby facilitating the movement of the temperature measuring head 1 in the liquid being measured, and thus making it easy to move the temperature measuring head 1 to the required position for measurement.

[0042] In a preferred embodiment, the system also includes a water injection pipe 82, an inner flange 84, and an outer flange 83. The pressure pipe 4 is connected to the water injection pipe 82 via the inner flange 84 and the outer flange 83, with a gasket 85 installed between the flanges. Bolt holes are evenly arranged circumferentially on the flanges and gasket 85, and the connection is sealed and fixed with pressure-bearing bolts to ensure good sealing between the pressure pipe 4 and the water injection pipe 82. This design effectively prevents water leakage during the water injection process, ensuring efficient system operation.

[0043] It should be noted that the water injection pipe 82, inner flange 84 and outer flange 83 are installed at one end of the pressure pipeline 4 for pressure testing of the pressure pipeline 4.

[0044] In a preferred embodiment, a stop valve 81 is installed on the upper part of the water injection pipe 82. During the pressure test, the operator opens the stop valve 81 to continuously inject water into the pressure pipe 4. When the pressure gauge 6 in the pressure pipe 4 shows that the predetermined pressure value has been reached, the operator closes the stop valve 81. This design can precisely control the water pressure injection, ensure the stability of the pressure in the pipe, and provide a reliable guarantee for further temperature measurement and data acquisition.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
