They are widely used in fields such as water conservancy, environmental protection, and scientific research. In terms of application scenarios, in the monitoring of natural water bodies such as rivers and lakes, they can provide real-time feedback on flow velocity, providing a basis for ecological assessment and flood and drought prevention; in urban drainage systems, they can monitor sewage flow velocity, assisting in pipe network maintenance and sewage treatment; in industrial production processes, they can monitor the flow velocity of process water such as cooling water, ensuring stable production.

[0003] Existing water quality and flow velocity monitors need to improve their operational stability in cold, high-altitude environments, as well as their flexibility in monitoring waters with varying flow directions, and their overall practicality needs to be enhanced. Utility Model Content

[0004] The purpose of this invention is to provide a high-altitude antifreeze water quality flow velocity monitor that can effectively cope with the cold environment of high altitudes and flexibly adapt to complex and ever-changing water flow directions, making it highly practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A plateau-resistant, freeze-resistant water flow rate monitor includes a float. The float has mounting holes on its outer surface, and a bearing is snapped into the mounting holes. A connecting pipe is snapped into the central shaft of the bearing. A detection tube is fixedly connected to one end of the connecting pipe. The detection tube has an internal interlayer, and a spiral-shaped resistance heating tube is installed inside the interlayer. A guide plate is fixedly connected to the upper end of the arc-shaped outer surface of the detection tube. Two insertion holes are provided on the outer surface of the float, and limit rods are inserted into the insertion holes.

[0007] By adopting the above technical solutions, we can effectively cope with cold environments and complex and ever-changing water flow directions, which is highly practical.

[0008] Furthermore, two inclined opposing mounting seats are provided on the side surface of the detection tube. An ultrasonic transducer is snapped into the mounting hole of the mounting seat. The two ultrasonic transducers are coaxially opposite each other and both face the inside of the detection tube.

[0009] By adopting the above technical solution, effective water flow velocity monitoring can be carried out.

[0010] Furthermore, an ultrasonic flow meter main unit is installed at the upper end of the connecting pipe, and the ultrasonic flow meter main unit is electrically connected to two ultrasonic transducers.

[0011] By adopting the above technical solution, stable ultrasonic flow velocity detection operation is ensured.

[0012] Furthermore, a second bracket is installed at one end of the lower surface of the float, and a temperature sensor is installed at one end of the second bracket.

[0013] By adopting the above technical solution, water temperature can be detected in real time.

[0014] Furthermore, a third bracket is fixedly installed on the upper surface of the float box, a waterproof box is installed at the upper end of the third bracket, a temperature controller is fixedly installed inside the waterproof box, the temperature sensor is electrically connected to the temperature controller, and the temperature controller is electrically connected to the resistance heating tube.

[0015] By adopting the above technical solution, temperature control and adjustment operations can be performed, ensuring that the heating structure can work in a timely manner.

[0016] Furthermore, the interior of the waterproof box is equipped with a storage battery, a charge / discharge controller, and an inverter. A first bracket is fixedly installed on the upper surface of the floating box, and a photovoltaic panel assembly is fixedly installed at the upper end of the first bracket. The photovoltaic panel assembly is electrically connected to the charge / discharge controller, and the charge / discharge controller is electrically connected to both the storage battery and the inverter.

[0017] By adopting the above technical solutions, effective photovoltaic power generation can be achieved.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows the float box to be placed directly in a designated water area during monitoring. The detection tube is then submerged in the water. Because guide plates are installed on the outer surface of the detection tube, and the connecting pipe is rotatably connected to the float box, the orientation of the detection tube can be adjusted in real time according to the water flow, ensuring that the water flow passes through the detection tube stably and orderly. As the water flows through the detection tube, two ultrasonic transducers alternately emit and receive ultrasonic waves. The ultrasonic flowmeter host can then effectively calculate the water flow velocity using the time-of-flight method and achieve remote data transmission through the wireless communication module inside the ultrasonic flowmeter host. Furthermore, during the entire monitoring process, a resistance heating tube can be used to heat the detection tube, thereby increasing the internal temperature of the tube and preventing freezing at the detection structure in cold, high-altitude environments, thus ensuring the stable operation of the entire monitor.

[0020] 2. This utility model can use photovoltaic panel components to convert light energy into electrical energy, which can be stored inside the battery under the control of the charge and discharge controller. Then, when in use, it provides stable power to the detection structure, further improving the stability of the device's operation. Attached Figure Description

[0025] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 , Figure 2 , Figure 3A high-altitude, freeze-resistant water flow rate monitor includes a float box 1. The float box 1 has mounting holes on its outer surface, and bearings are snapped into the mounting holes. A connecting pipe 7 is snapped into the central shaft of the bearing. One end of the connecting pipe 7 is fixedly connected to a detection pipe 8. The detection pipe 8 has an internal interlayer, and a spiral resistance heating tube 18 is installed inside the interlayer. A guide plate 10 is fixedly connected to the upper end of the arc-shaped outer surface of the detection pipe 8. The float box 1 has two insertion holes on its outer surface, and limit rods 2 are inserted into the insertion holes. The detection pipe 8 has two inclined, opposing mounting seats 9 on its side surface. Ultrasonic transducers are snapped into the mounting holes of the mounting seats 9. The two ultrasonic transducers are coaxially opposite and both face the inside of the detection pipe 8. An ultrasonic flow meter main unit 13 is installed at the upper end of the connecting pipe 7. The ultrasonic flow meter main unit 13 is electrically connected to the two ultrasonic transducers. [The last sentence appears to be incomplete and possibly refers to a separate device or mechanism.] During monitoring, the float box 1 is placed directly in the designated water area, and the detection tube 8 is placed in the water. Since the guide plate 10 is set on the outer surface of the detection tube 8 and the connecting pipe 7 is rotatably connected to the float box 1, the orientation of the detection tube 8 can be adjusted in real time according to the water flow, ensuring that the water flow can pass through the inside of the detection tube 8 stably and orderly. When the water flow passes through the inside of the detection tube 8, the two ultrasonic transducers alternately emit and receive ultrasonic waves. At this time, the ultrasonic flow meter host 13 can effectively calculate the water flow velocity according to the time difference method, and realize remote data transmission operation through the wireless communication module inside the ultrasonic flow meter host 13. In addition, during the entire monitoring process, the resistance heating tube 18 can be used to heat the detection tube 8 to increase the internal temperature of the detection tube 8, avoid freezing at the detection structure in the cold environment of the plateau, and ensure the stable operation of the entire monitor.

[0027] Reference Figure 1 , Figure 2 , Figure 3 A second bracket 5 is installed at one end of the lower surface of the float box 1, and a temperature sensor 6 is installed at one end of the second bracket 5. A third bracket 11 is fixedly installed on the upper surface of the float box 1, and a waterproof box 12 is installed at the upper end of the third bracket 11. A thermostat 14 is fixedly installed inside the waterproof box 12. The temperature sensor 6 is electrically connected to the thermostat 14, and the thermostat 14 is electrically connected to the resistance heating tube 18. During operation, the temperature sensor 6 can monitor the water temperature in real time and transmit the temperature data to the inside of the thermostat 14. When the temperature is lower than the set value, the thermostat 14 closes the working circuit of the resistance heating tube 18, and the resistance heating tube 18 starts to work, thereby increasing the temperature of the detection tube 8 and ensuring stable operation.

[0028] Reference Figure 2The waterproof box 12 houses a battery 15, a charge / discharge controller 16, and an inverter 17. A first bracket 3 is fixedly mounted on the upper surface of the float box 1, and a photovoltaic panel assembly 4 is fixedly mounted on the upper end of the first bracket 3. The photovoltaic panel assembly 4 is electrically connected to the charge / discharge controller 16, which is electrically connected to both the battery 15 and the inverter 17. The photovoltaic panel assembly 4 can convert light energy into electrical energy, which can be stored inside the battery 15 under the control of the charge / discharge controller 16. When in use, it provides stable power to the detection structure, further improving the stability of the device's operation.

[0029] Working Principle: During use, the float 1 is placed directly in the designated water area, and the limit rod 2 limits its position. At this time, the detection tube 8 is submerged in the water. Because guide plates 10 are installed on the outer surface of the detection tube 8, and the connecting pipe 7 is rotatably connected to the float 1, the orientation of the detection tube 8 can be adjusted in real time according to the water flow, ensuring that the water flow passes through the detection tube 8 stably and orderly. When the water flows through the detection tube 8, the two ultrasonic transducers alternately emit and receive ultrasonic waves. At this time, the ultrasonic flow meter main unit 13 can effectively calculate the water flow velocity using the time difference method, and then transmit the velocity through the wireless communication module inside the ultrasonic flow meter main unit 13. The remote data transmission operation, as well as the entire monitoring process, utilizes temperature sensor 6 to monitor the water temperature in real time and transmits the temperature data to the internal temperature controller 14. When the temperature drops below the set value, the temperature controller 14 closes the working circuit of the resistance heating tube 18, and the resistance heating tube 18 starts working to increase the temperature of the detection tube 8, preventing freezing at the detection structure in the cold high-altitude environment and ensuring the stable operation of the entire monitor. Throughout the process, the photovoltaic panel module 4 converts light energy into electrical energy, which can be stored inside the battery 15 under the control of the charge and discharge controller 16, and then provides stable power to the detection structure when in use.
