Technical Field

[0001] This application relates to the technical field of hydrological monitoring, and particularly to a vision flowmeter. Background Art

[0002] In hydrological monitoring, flow measurement is one of the very important parameters. At present, common flow measurement methods include traditional mechanical flowmeters and modern electronic flowmeters. Traditional mechanical flowmeters are limited by the water body cleanliness and flow velocity changes, and are prone to failures. Although electronic flowmeters have certain accuracy and reliability, there are still certain difficulties in installation and maintenance.

[0003] In addition, existing flowmeters mostly adopt contact measurement methods, which are easily affected by impurities in the water, resulting in an increase in measurement errors. Moreover, due to the long-term use of the flowmeter, especially in a hot summer environment, the measurement accuracy will decrease or even the instrument life will be reduced due to overheating of internal components.

[0004] Therefore, it is particularly important to develop a non-contact flow measurement device with high precision, easy installation and maintenance. Utility Model Content

[0006] Specifically, this application provides a vision flowmeter, which includes a housing. A vision cavity and a ranging cavity communicating with the inside of the housing are provided at the bottom of the housing. A vision acquisition device for collecting water body image data is installed in the vision cavity, and a rangefinder for measuring the distance to the water surface is installed in the ranging cavity; a heat dissipation part is provided at the upper part of the housing.

The heat sink includes a flat part connected to the housing and a convex part extending upward relative to the flat part. The convex part is provided at one end of the heat sink; the convex parts of each heat sink are arranged in a staggered and parallel manner.

[0008] In an alternative implementation, the housing includes an upper housing and a lower housing, and the upper housing and the lower housing are joined and connected; both sides of the upper housing are composed of upper inclined plates that slope outward, and both sides of the lower housing are composed of lower inclined plates that slope outward; a plurality of installation parts for installing the vision flowmeter are provided on the upper housing.

[0009] In an alternative implementation, the vision flowmeter includes a control main board, and the control main board is electrically connected to the vision acquisition device and the rangefinder.

[0010] In an alternative implementation, the visual current meter further includes a calculation component for calculating and processing image data and distance data, and a data transmission component for wireless signal transmission and reception. The calculation component and the data transmission component are electrically connected to the control main board.

[0011] According to the technical solution provided by the foregoing implementation, the visual current meter has at least the following advantages:

[0012] (1) The combination of the visual acquisition device and the rangefinder enables the device to simultaneously obtain the image and distance information of the water body. Through subsequent image processing algorithms, the flow velocity and flow rate of the water body can be measured more accurately, improving the accuracy and reliability of the measurement.
