Description

Technical Field

[0001] This application relates to the technical field of measuring equipment, and in particular to a portable measuring mechanism. Background Technology

[0002] In modern industrial production and urban infrastructure construction, pipeline systems are widely used in many fields such as petroleum, chemical, energy, and water supply and drainage. As a key component of pipeline systems, monitoring the operational status of valves is crucial for ensuring the safe, stable, and efficient operation of the pipeline system. Accurately measuring the pressure and temperature parameters at valve locations is an important means of assessing valve operating conditions and preventing potential failures.

[0003] In existing technologies, there are mechanisms for separately measuring valve pressure and separately measuring valve temperature. However, these separate measuring mechanisms have many drawbacks. On the one hand, their structural design is often relatively simple, and their function is limited to measuring a single parameter, which cannot meet the needs of simultaneous measurement of multiple parameters in practical applications. Utility Model Content

[0004] To increase the functionality of a single measuring mechanism, this application provides a portable measuring mechanism.

[0005] The portable measuring mechanism provided in this application adopts the following technical solution:

[0006] A portable measuring mechanism includes a housing and a measuring host fixedly connected inside the housing. A first pressure sensor, a second pressure sensor, and a temperature sensor interface are fixedly connected inside the housing. A first air path interface is installed on the first pressure sensor, a second air path interface is installed on the second pressure sensor, and a temperature sensor is connected to the temperature sensor interface. An antenna interface is installed on the measuring host. The measuring host is electrically connected to the first pressure sensor, the second pressure sensor, and the temperature sensor.

[0007] By adopting the above technical solution, the pressure of the pipeline can be measured through the first and second gas lines, and the differential pressure can be obtained by measuring the difference between the first and second pressure sensors. Simultaneously, the temperature of the pipeline can be measured by a temperature sensor, and the data can be uploaded to other devices in real time via an antenna interface. Thus, the same device can perform data upload, temperature measurement, and differential pressure measurement functions, thereby improving the convenience of pipeline measurement work.

[0008] Optionally, a rubber protective cover is fitted onto the housing.

[0009] By adopting the above technical solution, the side wall of the casing can be protected by a rubber protective sleeve.

[0010] Optionally, a limiting groove is formed on the housing opposite to the rubber protective sleeve, and the rubber protective sleeve is placed in the limiting groove.

[0011] By adopting the above technical solution, the position of the rubber protective sleeve can be restricted by the limiting groove, thereby improving the stability of the rubber protective sleeve within the limiting groove.

[0012] Optionally, both the first and second air passage interfaces are provided with rubber sealing caps, and a connecting component for connecting the two is provided between the rubber sealing caps and the rubber protective sleeve.

[0013] By adopting the above technical solution, when no measurement is being performed, the first gas path junction and the second gas path interface can be protected by rubber sealing plugs.

[0014] Optionally, the connecting assembly includes a connecting rope, one end of which is fixedly connected to the rubber protective sleeve, and the other end of which is fixedly connected to a limiting ring. An annular groove is formed on the outer wall of the rubber sealing cover, surrounding the outer wall of the rubber sealing cover, and the limiting ring is placed inside the groove.

[0015] By adopting the above technical solution, the rubber sealing cap and the rubber protective sleeve can be connected by a connecting rope and a limiting ring, thereby reducing the occurrence of loss of the rubber sealing cap.

[0016] Optionally, the connecting rope is made of rubber and is integrally formed with the rubber protective sleeve.

[0017] By adopting the above technical solution, the stability of the connection between the connecting rope and the rubber protective sleeve can be improved.

[0018] Optionally, a placement rod is fixedly connected to the side wall of the housing, and when the first pressure sensor and the second pressure sensor are activated, the rubber sealing cap is sleeved on the placement rod.

[0019] By adopting the above technical solution, when the first pressure sensor and the second pressure sensor are activated, the rubber protective sleeve can be restricted by the placement rod.

[0020] Optionally, the outer wall of the rubber protective sleeve is provided with multiple anti-slip vertical grooves.

[0021] By adopting the above technical solution, the anti-slip vertical grooves can increase the friction between the rubber protective sleeve and the hands of the testing personnel, reducing the occurrence of slippage of the testing mechanism.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The pressure in the pipeline can be measured through the first and second gas lines, and the differential pressure can be obtained by measuring the difference between the first and second pressure sensors. Simultaneously, the temperature of the pipeline can be measured through the temperature sensor interface, and the data can be uploaded to other devices in real time through the antenna interface. Thus, the same device can perform data upload, temperature measurement, and differential pressure measurement functions, thereby improving the convenience of pipeline measurement work.

[0024] 2. The position of the rubber protective sleeve can be restricted by the limiting groove, thereby improving the stability of the rubber protective sleeve within the limiting groove;

[0025] 3. When no measurement is being performed, the first gas path junction and the second gas path interface can be protected by rubber sealing caps. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0031] Example 1

[0032] A portable measuring mechanism, referring to Figure 1 and Figure 2The device includes a housing 1, within which a measuring host 2 is fixedly connected. A first pressure sensor 3, a second pressure sensor 4, and a temperature sensor interface 51 are also fixedly connected within the housing 1. Both the first pressure sensor 3 and the second pressure sensor 4 are located on the upper part of the housing 1. The first pressure sensor 3 is fixedly connected to and connected to a first air path interface 31, and the second pressure sensor 4 is fixedly connected to and connected to a second air path interface 41. A temperature sensor 5 is detachably connected to and connected to the temperature sensor interface 51. An antenna interface 21 is installed on the measuring host 2, which is used to transmit data from the measuring host 2 externally. The measuring host 2 is electrically connected to the first pressure sensor 3, the second pressure sensor 4, and the temperature sensor 5, and is used to receive information from these sensors.

[0033] The implementation principle of Example 1 is as follows: The pressure of the pipeline is measured through the first gas interface 31 and the second gas interface 41, and the pressure difference is obtained by the difference between the first pressure sensor 3 and the second pressure sensor 4. The pressure difference value is then transmitted to the measuring host 2 for display. The temperature of the pipeline is measured by the temperature sensor 5 and transmitted to the measuring host 2 for display. Data can be uploaded to other devices in real time via the antenna interface 21.

[0034] Example 2

[0035] The difference from Example 1 is that: (Refer to...) Figure 3 The housing 1 has a limiting groove 11 surrounding it, and a rubber protective sleeve 6 is fitted inside the limiting groove 11. The outer wall of the rubber protective sleeve 6 has multiple anti-slip vertical grooves 61. Rubber sealing caps 7 are fitted at both the first air passage interface 31 and the second air passage interface 41. The rubber protective sleeve 6 is used to protect the first air passage interface 31 and the second air passage interface 41.

[0036] A connecting component 8 is provided between the rubber sealing cap 7 and the rubber protective sleeve 6 to connect the two. The connecting component 8 includes a connecting rope 81, which in this embodiment is made of rubber and is integrally formed with the rubber protective sleeve 6. One end of the connecting rope 81 is fixedly connected to the rubber protective sleeve 6, and the other end of the connecting rope 81 is fixedly connected to a limiting ring 82. An annular groove 71 is formed on the outer wall of the rubber sealing cap 7, and the limiting ring 82 is placed in the limiting groove 11 and is restricted by the rubber sealing cap 7 within the annular groove 71.

[0037] A placement rod 12 is fixedly connected to the side wall of the housing 1. When the first pressure sensor 3 and the second pressure sensor 4 are activated, the rubber sealing cover 7 is sleeved on the placement rod 12.

[0038] The implementation principle of Example 2 is as follows: When no measurement is being performed, the first gas path junction and the second gas path interface 41 can be protected by the rubber sealing cap 7. When the first pressure sensor 3 and the second pressure sensor 4 are activated, the rubber sealing cap 7 can be fitted onto the placement rod 12, and the rubber protective sleeve 6 can be restricted by the placement rod 12.
