Description

Technical Field

[0001] This invention belongs to the field of pipeline pressure measurement technology, and more specifically, relates to a pipeline pressure sensor and its installation method. Background Technology

[0002] my country will comprehensively launch urban infrastructure lifeline safety projects, including urban gas, bridges, water supply, drainage, heating, electricity, elevators, communications, rail transit, integrated utility tunnels, and oil pipelines. These infrastructures bear important responsibilities for urban information transmission, energy delivery, flood control, and disaster reduction. They are crucial infrastructure for maintaining the normal operation of cities and meeting the needs of people's production and daily life; they are the lifelines of cities. Infrastructure lifelines are like the "nerves" and "blood vessels" of the human body, ensuring the safe operation of cities.

[0003] Over a century of urban development has resulted in a network of underground pipelines for various transportation services. Some water pipes, due to age and disrepair, suffer severe leaks, frequently causing ground subsidence and resulting in accidents involving vehicles and fatalities. Gas pipeline leaks also cause fires and explosions, which occur from time to time; burst heating pipelines cause heating outages, posing a significant threat to people's lives and property.

[0004] The Urban Infrastructure Lifeline Safety Project aims to use digital means to detect and manage risks and hidden dangers early, effectively improve urban safety capabilities, safeguard people's lives and property, make cities healthier, safer, and more livable, and continuously enhance the people's sense of gain, happiness, and security.

[0005] However, due to the various pipelines being distributed both underground and above ground and constantly in operation, it is extremely difficult to install various monitoring sensors, and the construction costs are too high, which brings great difficulties to obtaining big data. Summary of the Invention

[0006] In view of this, the present invention provides a pipeline pressure sensor and its installation method, which can solve the problems of difficulty in installing existing sensors, high construction costs, and difficulty in obtaining big data.

[0007] This invention is implemented as follows:

[0008] This invention provides a pipeline pressure sensor, which includes a sensor mounting mechanism, a sealing mechanism, a pressure monitoring mechanism, and a signal transmission mechanism;

[0009] The sensor mounting mechanism is located at the bottom of the sensor and is used to fix the sensor on the pipeline to measure the pressure value inside the pipeline in real time.

[0010] The sealing mechanism is disposed between the pipeline and the sensor mounting mechanism, and is used to seal the pipeline pressure sensor to the pipeline.

[0011] The pressure monitoring mechanism is located on top of the sensor mounting mechanism and is used to monitor the pressure value inside the pipeline in real time.

[0012] The signal transmission mechanism is located above the pressure monitoring mechanism and is electrically connected to the pressure monitoring mechanism. It is used to transmit the pressure value inside the pipeline monitored by the pressure monitoring mechanism to the monitoring terminal.

[0013] Based on the above technical solution, the pipeline pressure sensor of the present invention can be further improved as follows:

[0014] The sensor mounting mechanism includes a sensor mounting housing, stainless steel nails, and plugs. The sensor mounting housing is located near the pipe and has a hollow interior. The hollow interior serves as a sealed channel, and the opening of the sealed channel is sealed by the plugs. Two stainless steel nails are movably disposed between the sensor mounting housing and the pipe to fix the pipe pressure sensor onto the pipe.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a sensor mounting housing, the component for measuring pipeline pressure can be fixed inside; by setting stainless steel nails, it is convenient to fix the device for measuring pipeline pressure on the pipeline, and the pressure inside the pipeline can be measured in real time.

[0016] Furthermore, the stainless steel nail includes a steel nail, a cartridge case, and a groove. The cartridge case is fixed to the top of the steel nail to provide power for the steel nail to drive the pipeline pressure sensor to be fixed on the pipeline. The steel nail has multiple grooves on its side, which are used to introduce the pressure inside the pipeline into the sensor.

[0017] Furthermore, the cartridge case is equipped with a double-base propellant, which is used to fix the sensor to the pipeline and measure the pressure value inside the pipeline in real time.

[0018] Furthermore, the sealing mechanism includes a sealing element and a self-sealing element. The sealing element is disposed between the stainless steel nail, the sensor mounting housing, and the pipe to seal the sensor mounting housing and the pipe. A central guide post is provided at the middle position of the sensor mounting housing, and the self-sealing element is sleeved on the central guide post.

[0019] The sealing element includes an upper sealing element and a lower sealing element. The upper sealing element is located at the top of the stainless steel nail and abuts against the inside of the sensor mounting housing to seal the sensor mounting housing and the stainless steel nail. The lower sealing element is located at the bottom of the stainless steel nail and abuts against the pipe to seal and fix the pipe pressure sensor on the pipe.

[0020] The upper and lower seals are made of rubber and resin.

[0021] Furthermore, the self-sealing component is also provided with a sealing gasket, a spring, and a partition. The top of the self-sealing component is provided with a partition, the bottom of the self-sealing component is provided with a spring, and the top of the partition is provided with the sealing gasket. The sealing gasket, the partition, the self-sealing component, and the spring are all in contact.

[0022] The side of the partition is set as a slope, which matches the slope of the self-sealing component.

[0023] Furthermore, the pressure monitoring mechanism includes a pressure sensor and a mounting probe. The mounting probe is installed at the top of the self-sealing component, and the pressure sensor is positioned above the sensor mounting housing. A pressure channel is formed between the pressure sensor, the self-sealing component, and the mounting probe. The pressure channel is used to introduce the pressure inside the pipe into the sensor for measurement.

[0024] Furthermore, the signal transmission mechanism is a controller, which is fixed on top of the pressure sensor. A signal line is provided between the controller and the pressure sensor for transmitting pressure signals. The controller is equipped with a communication device, which can be either wired or wireless, for transmitting pressure data inside the pipeline to a monitoring terminal or monitoring platform.

[0025] Furthermore, the controller is equipped with a lithium battery that is electrically connected to the controller to supply power to the controller.

[0026] This invention provides a method for installing a pipeline pressure sensor, comprising the following installation steps:

[0027] The first step is to axially attach the pipeline pressure sensor to the pipeline, so that the sensor mounting housing fits into the pipeline.

[0028] The second step is to use an integrated double-muzzle nail gun to mount the stainless steel nail, press down to fire, and under the power of the gunpowder inside the cartridge case, the stainless steel nail will penetrate the outer shell of the pipe.

[0029] The third step is to seal and fix the stainless steel nail to the pipe using the sealing element and the self-sealing element.

[0030] In the fourth step, the installation probe presses down the self-sealing component, screws in the pressure sensor and the controller in sequence, connects them to the sensor mounting housing, and measures the pressure inside the pipe.

[0031] Compared with existing technologies, the advantages of the pipeline pressure sensor and its installation method provided by this invention are as follows: By setting a sensor mounting housing, the component for measuring pipeline pressure is fixed inside; by setting stainless steel nails, the device for measuring pipeline pressure is easily fixed to the pipeline, enabling real-time measurement of the pressure inside the pipeline; by setting plugs, the inside of the sensor mounting housing is sealed; by setting sealing elements and self-sealing elements, the sensor mounting housing is sealed to the pipeline, facilitating the detection of the pressure value inside the pipeline; and by setting a pressure sensor, the problems of difficult installation, high construction costs, and difficulty in obtaining large amounts of data associated with existing sensors are solved.

The pressure data inside the pipeline is transmitted to the monitoring terminal or monitoring platform through the communication device.
