[0022] The technical scheme of the present application will be further specifically explained below by embodiments, and in combination with the drawings.

[0023] For example, Figures 1 to 2 ​​As shown in the figure, a pipeline pressure detection device comprises a pressure detection probe 3, a controller, and a power supply mechanism for supplying power to the controller. The pressure detection probe 3 is at least partially arranged in the pipeline 200. The controller is connected to the pressure detection probe 3 to transmit signals. The power supply mechanism comprises a magnet 5, a coil winding 6, an impeller 7, a rectifier regulator, and a battery. The coil winding 6 is sleeved on the magnet 5 and connected to the controller through the rectifier regulator and the battery. The magnet 5 is in transmission connection with the impeller 7. The impeller 7 is located on the water flow path in the pipeline and can be driven by the water flow in the pipeline.

[0024] Through the above arrangement, the battery supplies power to the pressure detection device, which can normally detect the pipeline pressure when the water flow in the pipeline stops moving. When the water flow in the pipeline moves, the impeller 7 can be driven to charge the battery, preventing the battery from running out of power, so that the pressure detection device can move for a long time, avoiding frequent replacement of the battery.

[0025] When the pressure detection device of the present application is used, the pressure detection probe 3 penetrates through the side wall of the pipeline and is fixedly connected with the pipeline. The detection end of the pressure detection probe 3 extends into the pipeline to detect the water pressure. The pressure detection probe 3 can be directly purchased from the market. The controller is used to read the data of the pressure detection probe 3 and transmit the data to the background for analysis by the background staff. Specifically, the controller can adopt PLC or single-chip microcomputer. The battery supplies power to the controller and can adopt lithium battery with good energy density. The outer side of the battery can be wrapped with waterproof and heat-insulating material to improve the safety of the battery. When the water flow in the pipeline passes through the impeller 7, the impeller 7 rotates to drive the magnet 5 to rotate in the coil winding 6. The coil winding 6 cuts the magnetic induction lines to generate electromotive force. The rectifier regulator regulates the voltage to charge the battery.

[0026] As an implementation manner, the pressure detection device further comprises a wireless mechanism connected with the controller to wirelessly transmit and receive signals.

[0027] Through the above arrangement, the signals are transmitted in a wireless form to reduce the wiring and facilitate construction.

[0028] The wireless mechanism of the present application can adopt a Bluetooth module or a Wi-Fi module or a 5G module to send the data read by the controller to the background in a wireless form.

[0029] As an implementation manner, the power supply mechanism further comprises a first housing 8 and a first support 9 fixedly connected in the first housing 8. The first housing 8 is sealingly installed between two adjacent pipelines. The two adjacent pipelines are connected through the first housing 8. The coil winding 6 is fixedly connected to the inner wall of the first housing 8. The impeller 7 is in rotational connection with the first support 9. The rotation axis of the impeller 7 is parallel to the direction of the water flow. The magnet 5 is fixedly connected to the outer wall of the impeller 7.

[0030] The first shell 8 of the application is substantially cylindrical, coaxially installed between two adjacent pipes, and supports the impeller 7 through the first support 9. The ratio of the outer diameter of the impeller 7 to the inner diameter of the pipe is greater than 70%, so that the impeller 7 has sufficient driving force. When the water flows through the impeller 7, the magnet 5 at the edge of the impeller 7 rotates, thereby generating electricity for the battery.

[0031] As an implementation manner, the first shell 8 is connected with the pipe end through threads, or the first shell 8 is fused with the pipe end.

[0032] Through the above arrangement, the first shell 8 is sealed and connected with the pipe.

[0033] As an implementation manner, the inner diameter of the pipe is less than 20 mm.

[0034] When the inner diameter of the pipe is less than 20 mm, in order to ensure sufficient driving force of the impeller 7, the ratio of the outer diameter of the impeller 7 to the inner diameter of the pipe is greater than 70%, and in order to facilitate the installation of the impeller 7, the power supply mechanism is installed between adjacent pipes.

[0035] In another embodiment, as shown in Figures 3 to 4 The power supply mechanism further includes a second shell 10 and a transmission shaft 13. The pipe upper side is provided with a mounting port 11, the second shell 10 is fixedly connected to the upper side of the pipe and seals the mounting port 11, the coil winding 6 is fixedly connected to the inner wall of the second shell 10, and the transmission shaft 13 is vertically rotatably connected in the second shell 10. The upper end of the transmission shaft 13 is fixedly connected with the magnet 5, and the lower end extends into the pipe and is fixedly connected with the impeller 7.

[0036] The second shell 10 of the application is substantially vertically extending cylindrical, and is sealed and installed on the upper side of the mounting port 11. The coil winding 6 is installed on the inner wall of the upper end of the second shell 10. The mounting port 11 is circular and has a diameter greater than the outer diameter of the impeller 7, facilitating the installation of the impeller 7 into the pipe. When the water flows through the impeller 7, the impeller 7 drives the magnet 5 to rotate through the transmission shaft 13, thereby generating electricity for the battery.

[0037] As an implementation manner, the power supply mechanism further includes a second support 12 fixedly connected in the second shell 10, and the transmission shaft 13 penetrates the second support 12 and is fixedly connected with the second support 12.

[0038] Through the above arrangement, the transmission shaft is vertically rotatably connected in the second shell 10 through the second support 12.

[0039] The second support 12 of the application is arranged between the impeller 7 and the magnet 5, and the transmission shaft 13 is axially fixed on the second support 12, that is, the rotation shaft can only rotate but cannot move up and down, so as to ensure the stability of the magnet 5 when rotating.

[0040] As an implementation manner, the inner diameter of the pipe is greater than or equal to 20 mm.

[0041] When the pipe diameter of the present application is large, the upper installation port 11 can be opened larger, so that the impeller 7 installed in the pipe has sufficient driving force, and the power supply mechanism can be installed on the upper side of the pipe with the installation port 11, so that the pipe is less likely to leak water.
