Description

Technical Field

[0001] This utility model belongs to the field of chemical safety technology, and more specifically, it relates to a chemical pipeline safety detector. Background Technology

[0002] A chemical pipeline safety detector is an instrument used to detect potential safety hazards such as leaks and corrosion in chemical pipelines. It uses sensors to sense changes in gas concentration within the pipeline and converts these changes into electrical signals. These signals are then analyzed by a data acquisition and processing system to determine if a gas leak is present. When the detected gas concentration reaches a set safety alarm value, the instrument will trigger an audible and visual alarm. However, the sensors in commonly used chemical pipeline safety detectors may age after prolonged use, affecting their functionality and creating safety hazards. Therefore, a new type of chemical pipeline safety detector is needed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a chemical pipeline safety detector, which solves the problem that the sensors of existing chemical pipeline safety detectors may age after prolonged use, affecting their use and causing safety hazards.

[0004] This utility model relates to a chemical pipeline safety detector, achieved through the following specific technical means:

[0005] A safety detector for chemical pipelines includes a main body, a casing, and a pressure gauge;

[0006] The main body has connectors at both ends and a round hole at the top. The outer shell is placed on the top of the main body, and the top surface of the main body is fixedly connected to the bottom surface of the outer shell. A display screen is installed on the top of the outer shell. A square groove is provided on the right side of the outer shell, and two sets of slots are provided in the square groove. A movable plate is installed in the square groove. A circular groove is provided on the rear side of the outer shell. The pressure gauge is placed in the circular groove on the rear side of the outer shell and is electrically connected to the display screen.

[0007] Furthermore, the lower end of the pressure gauge is connected to a connecting pipe, the lower end of which extends out of the outer shell, passes through the round hole at the upper end of the main body, and enters the main body.

[0008] Furthermore, an alarm is installed on the left rear end of the housing, and an indicator light A is provided on the top of the alarm. The indicator light A and the alarm are electrically connected to the pressure gauge.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a chemical pipeline safety detector, including a main body 1, a shell 3, and a pressure gauge 4;

[0025] The main body 1 has connectors 2 at both ends and a round hole at the top. The outer shell 3 is placed on the top of the main body 1 and the top surface of the main body 1 is fixedly connected to the bottom surface of the outer shell 3. A display screen 6 is installed on the top of the outer shell 3. A square groove is provided on the right side of the outer shell 3 and two sets of slots are provided in the square groove. A movable plate 7 is installed in the square groove. A circular groove is provided on the rear side of the outer shell 3. A pressure gauge 4 is placed in the circular groove on the rear side of the outer shell 3 and is electrically connected to the display screen 6.

[0026] Among them, such as Figure 2 and Figure 3 As shown, the lower end of pressure gauge 4 is connected to a connecting pipe 10. The lower end of the connecting pipe 10 extends out of the outer casing 3, passes through the upper circular hole of the main body 1, and enters the main body 1. An alarm 11 is installed on the left rear end of the outer casing 3, and an indicator light A5 is provided on the top of the alarm 11. The indicator light A5 and the alarm 11 are electrically connected to pressure gauge 4 and enter the main body 1 through the lower end of the connecting pipe 10, so that pressure gauge 4 can detect pressure changes inside the pipeline in real time and accurately, and dynamically monitor gas pressure fluctuations in the pipeline. Once the pressure exceeds the normal range, the alarm 11, which is electrically connected to pressure gauge 4, will immediately start and sound an alarm. At the same time, the indicator light A5 on the top will also light up, flashing a bright light to promptly remind the surrounding staff, so that the staff can respond quickly and take appropriate measures to ensure the safe operation of the chemical pipeline.

[0027] Among them, such as Figure 4As shown, an alarm 16 and an indicator light B17 are installed at the front end of the outer casing 3. The indicator light B17 is located near the upper side of the alarm 16. A groove is provided on the front side of the outer casing 3, and two sets of positioning holes 13 are provided at the left and right ends of the groove. A movable plate 8 is movably connected to the groove on the front side of the outer casing 3. Dustproof nets 9 are installed on the left and right sides of the movable plate 8. Two sets of positioning posts 12 are provided at the lower ends of the left and right sides of the movable plate 8, corresponding to the positioning holes 13. A data integration module 14 is installed inside the groove on the front side of the outer casing 3. Sensors 15 are connected to the left and right sides of the data integration module 14. The data integration module 14 is electrically connected to two sets of slots in the square groove on the right side of the outer casing 3. The two sets of sensors 15 are connected to the alarm 16 and... The indicator light B17 is electrically connected and corresponds to the positioning hole 13 via the positioning post 12, facilitating the maintenance or replacement of the sensor 15. The dustproof net 9 reduces the impact of dust and other impurities on the sensor 15. By inserting memory cards into the two sets of slots, the data of the sensor 15 can be recorded, facilitating subsequent observation of changes in the concentration of chemical gases in the surrounding environment. In addition, by comparing the two sets of sensors 15, it is possible to check whether the sensors 15 have aged or other problems, thereby improving the accuracy of data acquisition. When the two sets of sensors 15 sense a change in the concentration of gases in the surrounding environment, they will immediately transmit the signal to the electrically connected alarm 16 and indicator light B17, promptly issuing an alert so that staff can quickly grasp the environmental gas conditions.

[0028] The specific usage and function of this embodiment are as follows:

[0029] like Figures 1 to 4 As shown, in this utility model, the two ends of the utility model are connected to the pipeline, and the lower end of the connecting pipe 10 is inserted into the main body 1, so that the pressure gauge 4 can detect the pressure changes inside the pipeline in real time and accurately, and dynamically monitor the gas pressure fluctuations in the pipeline. Once the pressure exceeds the normal range, the alarm 11, which is electrically connected to the pressure gauge 4, will be activated immediately and sound an alarm. At the same time, the indicator light A5 on the top will also light up, and the bright light will flash to promptly remind the surrounding staff, so that the staff can respond quickly and take appropriate measures to ensure the safe operation of the chemical pipeline. By comparing the two sets of sensors 15, it is also possible to check whether the sensors 15 have aged or other problems, thereby improving the accuracy of data acquisition. When the two sets of sensors 15 sense a change in the gas concentration in the surrounding environment, they will immediately transmit the signal to the alarm 16 and indicator light B17, which are electrically connected to them, to issue a timely reminder and allow the staff to quickly grasp the environmental gas conditions.
