Description

Technical Field

[0001] This utility model belongs to the field of river detection technology, specifically relating to a cableway-type river flow measurement device. Background Technology

[0002] For wide rivers without bridges, cable-stayed flow measurement is necessary to achieve real-time online measurement. To ensure accurate measurements, several instruments (sensors) need to be installed on the cableway, depending on the river's width. Cable-stayed flow measurement devices are suitable for wide rivers without bridges, enabling real-time online measurement and offering certain advantages. However, existing cable-stayed flow measurement devices also have some problems. For example, the traveling support used to install the instruments (sensors) has poor wind resistance stability, which can easily affect the accuracy of the measurements. Especially due to gravity, the middle section of the cableway is curved, causing wheel slippage and difficulty in climbing when the traveling trolley is in the middle position. Furthermore, for cable-stayed flow measurement devices that need to operate in the field for extended periods, challenges arise regarding power supply, data transmission, and the reliability and durability of the equipment. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cableway-type river flow measurement device that drives reciprocating motion.

[0004] A cableway-type river flow measurement device includes a main column and a secondary column fixed on both sides of the river channel, a traveling cableway and a traction cableway matched between the main column and the secondary column, and a measuring trolley that can move back and forth along the traveling cableway driven by the traction cableway. A radar level gauge is fixedly installed at the bottom of the measuring trolley, and a winch mechanism is mounted on the measuring trolley. A measuring part is fixedly installed at the end of the hoisting rope of the winch mechanism. The measuring trolley is equipped with a first battery pack for driving the winch motor of the winch mechanism, and a first solar panel for storing energy of the first battery pack is set on the top.

[0005] As one preferred embodiment, a traction drive mechanism for driving the traction cableway is fixedly installed on the main column, including a traction motor, a traction pulley driven by the traction motor, and a guide pulley disposed on one side of the traction pulley to increase the contact angle between the traction cableway and the traction pulley.

[0006] As one preferred embodiment, the traction drive mechanism further includes a second battery pack for driving the traction motor, and a second solar panel for storing energy from the second battery pack is provided on the top of the main column, and the second solar panel is fixedly mounted on a rotatable bracket.

[0007] As one preferred embodiment, the traction drive mechanism further includes a stroke limiting integrated mechanism, which includes a first gear directly coaxially connected to the traction groove wheel, a second gear meshing with the first gear, a third gear meshing with the second gear, a limiting screw fixedly connected to the third gear on the same axis, a sliding contact block sleeved on the limiting screw and limited to horizontal movement, and proximity sensors correspondingly disposed at predetermined positions at both ends of the limiting screw. The second gear is coaxially connected to an encoder.

[0008] As one preferred embodiment, the second gear and the encoder are coaxially mounted on the rotating carrier plate, the rotation axis of the rotating carrier plate is coaxial with the third gear, and the rotating carrier plate is tensioned by a spring to keep it in contact with the first gear.

[0011] The advantages and beneficial effects of this utility model are as follows:

[0012] In terms of cableway design, this device adopts an innovative approach by separating the traveling cableway and the traction cableway. The two ends of the traveling cableway are securely connected and locked to the main and secondary columns respectively, ensuring the cableway's stability and preventing loosening. The traction cableway is driven by a traction drive mechanism on the main column side, with steering pulleys on the secondary column section. By controlling the forward and reverse rotation of the traction cableway, the measuring trolley can move back and forth above the river channel. Compared to the traditional method of setting traveling wheels on the measuring trolley, this design, where the traction cableway pulls the measuring trolley relative to the traveling cableway, can transmit driving force more efficiently. Especially when dealing with complex water flow environments and strong winds, it can effectively avoid the problem of trolley stalling caused by localized wear and icing of the traveling cableway, and completely solve the problem of insufficient driving force due to uneven friction in various parts of the traveling cableway. Furthermore, the radar level gauge at the bottom of the measuring trolley works in conjunction with the lifting measuring unit to obtain multiple key parameters such as liquid level, flow rate, and flow velocity in a single measurement, enabling rapid and accurate multi-point measurements within the river channel. Utilizing solar power greatly enhances the ease of deployment in complex field environments, reducing reliance on external power sources. Coupled with 4G or 5G signal transmission technology, it not only enables real-time transmission and storage of measurement information but also supports remote control, achieving intelligent operation.

[0022] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] This utility model provides a cableway-type river flow measurement device with ingenious structural design and practical function. A main column 1 and a secondary column 2 are fixed on opposite banks of the river. These two columns form a solid "foundation" by being sunk into a steel reinforcement base, providing stable support for the entire device. Between the main and secondary columns, a traveling cableway 3 and a traction cableway 4 are installed, with clear division of labor and mutual cooperation. The measuring trolley 5, driven by the traction cableway 4, can reciprocate along the traveling cableway 3. A radar level gauge 51 is fixedly installed at the bottom of the measuring trolley 5, and a winch mechanism 52 is also mounted on the trolley. The end of its hoisting rope is connected to the measuring unit 53. A first battery pack 54 is specifically used to drive the winch motor of the winch mechanism, while a first solar panel 55 at the top stores energy for the first battery pack 54.

[0024] In terms of cableway design, this device adopts an innovative approach by separating the traveling cableway and the traction cableway. The two ends of the traveling cableway are securely connected and locked to the main and secondary columns respectively, ensuring the cableway's stability and preventing loosening. The traction cableway is driven by a traction drive mechanism on the main column side, with steering pulleys on the secondary column section. By controlling the forward and reverse rotation of the traction cableway, the measuring trolley can move back and forth above the river channel. Compared to the traditional method of setting traveling wheels on the measuring trolley, this design, where the traction cableway pulls the measuring trolley relative to the traveling cableway, can transmit driving force more efficiently. Especially when dealing with complex water flow environments and strong winds, it can effectively avoid the problem of trolley stalling caused by localized wear and icing of the traveling cableway, and completely solve the problem of insufficient driving force due to uneven friction in various parts of the traveling cableway. Furthermore, the radar level gauge at the bottom of the measuring trolley works in conjunction with the lifting measuring unit to obtain multiple key parameters such as liquid level, flow rate, and flow velocity in a single measurement, enabling rapid and accurate multi-point measurements within the river channel. Utilizing solar power greatly enhances the ease of deployment in complex field environments, reducing reliance on external power sources. Coupled with 4G or 5G signal transmission technology, it not only enables real-time transmission and storage of measurement information but also supports remote control, achieving intelligent operation.

[0025] The traction drive mechanism on the main column is a key component ensuring the stable operation of the measuring trolley. It consists of a traction motor 41, a traction pulley 42, and two guide pulleys 43. The traction motor 41 drives the traction pulley 42 to rotate. The two guide pulleys 43 are mounted on one side of the traction pulley 42, cleverly increasing the contact angle between the traction cable and the traction pulley. The guide pulleys are rotatably fixed and are on the same horizontal plane as the traction pulley. The bottom of the upper guide pulley is lower than the top of the traction pulley, and the top of the lower guide pulley is higher than the bottom of the traction pulley, making the contact angle exceed 200°, significantly enhancing the driving force of the pulleys. Actual testing shows that, under the same motor power, this structure can improve traction efficiency by more than 30%, ensuring that the traction motor can stably perform its traction function under different working conditions. At the same time, the traction drive mechanism is equipped with a second battery pack 44 to power the traction motor, and a second solar panel 45 on the top of the main column stores energy for the second battery pack. The second solar panel is mounted on a rotatable bracket, which can be flexibly adjusted to the optimal angle of sunlight during installation and can also be dynamically adjusted according to seasonal changes to always maintain the best energy storage effect.

[0026] To improve the safety and accuracy of the device's operation, the traction drive mechanism is equipped with an integrated travel limit mechanism. This mechanism includes a first gear 61 coaxially connected to the traction pulley, a second gear meshing with the first gear, a third gear 63 meshing with the second gear 62, a limit screw 64 coaxially fixed to the third gear, a sliding contact block 65 sleeved on the screw, and proximity sensors 66 at both ends. The second gear is also coaxially connected to an encoder 69. This integrated design of the encoder and proximity limit sensor effectively avoids equipment damage due to encoder failure; by converting the travel distance into proximity sensor signals, high-precision limit control is achieved. The second gear and encoder are coaxially mounted on a rotating carrier plate 67, whose rotation axis is coaxial with the third gear. Under the action of a spring 68, the rotating carrier plate always maintains elastic contact with the first gear. It is worth mentioning that this elastic contact structure also has a certain self-compensation function; when the gears experience minor wear, the spring force can automatically adjust the meshing clearance between the gears, further extending the service life of the mechanism. This integrated measurement and limit mechanism is compact in size and combines encoder measurement and mechanical limit functions. It can accurately control the measurement point and greatly improve the accuracy of data such as liquid level measurement. The elastic contact design extends the service life of the mechanism and ensures stable operation in harsh environments.

[0027] In addition, a docking compartment 7 is located at the end of the main column facing the secondary column, specifically for the measurement trolley to enter and park. The top of the docking compartment is made of transparent materials such as glass or hard plastic, which not only protects the measurement trolley from problems such as rope stretching caused by long-term suspension on the cableway, but also does not affect the solar panels' ability to receive light and charge. The inward-protruding support plate at the bottom works in conjunction with the limiting guide plate at the bottom of the measurement trolley to effectively improve anti-interference capabilities. Furthermore, the docking compartment is equipped with a temperature and humidity control device and a simple cleaning brush, which can dehumidify and prevent moisture from affecting the equipment during the trolley's parking period, as well as clean the surface of the radar level gauge, further ensuring the accuracy of the measurement data. Even in windy weather, the measurement trolley will not detach from the docking compartment due to cableway swaying, fully ensuring the safety and stability of the parking.

[0028] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
