Description

Technical Field

[0001] The present invention relates to the technical field of flow velocity and direction meters, and particularly to a flow velocity and direction meter based on image recognition and a control method therefor. Background Technique

[0002] A flow velocity and direction meter is an instrument used to measure the flow velocity and direction of water. There are mainly flow velocity and direction meters based on the Doppler effect principle and the mechanical rotor principle. The principle of the Doppler effect flow velocity and direction meter is to emit ultrasonic waves or electromagnetic waves into the water and then receive the signals scattered back by the particles in the water. Due to the movement of the particles in the water, the frequency of the reflected signal will change, and the flow velocity can be calculated according to the Doppler frequency shift.

[0003] The principle of the mechanical rotor flow velocity and direction meter is that the instrument contains one or more rotors. When the water flows through, the rotors will rotate. By measuring the rotation speed of the rotors, the flow velocity can be deduced. For the measurement of the flow direction, a compass or other direction sensors are usually combined to determine the direction of the water flow.

[0004] When the existing flow velocity and direction meters are used for monitoring, they cannot effectively collect the image information of the water body and various features, objects, forms, positions, etc. in the water body. This results in that it is difficult for the flow velocity and direction meters to accurately measure the flow velocity and direction in the case of overly clear or overly turbid water bodies and small contrast of the monitoring images. They can only rely on data to judge the flow velocity and direction, which is prone to misjudgment or difficult to accurately grasp the actual situation of the water flow, causing inconvenience in use and reducing the use effect of the flow velocity and direction meters.

[0052] Working principle and usage process of the present invention: When in use, the underwater camera 41 can be started to observe the surrounding area through shooting. At the same time, the protective cover 43 can provide transparent protection for the outside of the underwater camera 41, improving the safety of using the underwater camera 41 and preventing the underwater camera 41 from colliding with other objects during movement, which may cause the underwater camera 41 to malfunction and be damaged and unable to shoot normally. Also, when the underwater camera 41 moves to the monitoring position during use, the user can start the electric push rod 47 according to the usage requirements, so that the output end of the electric push rod 47 pushes the positioning rod 46 to move. The movement of the positioning rod 46 can drive the protective cover 43, the positioning rod 46 and the camera to move, facilitating the movement of the camera to monitor the surrounding area through shooting and improving the monitoring range during use. The shooting and monitoring information of the underwater camera 41 can be transmitted to the display 9 through the integrated cable 3, facilitating the user to observe and judge the underwater information. Also, when the height of the position to be used needs to be adjusted, the hydraulic cylinder 56 can be started, so that the output end of the hydraulic cylinder 56 pushes the connecting plate 48 to move. The movement of the connecting plate 48 can drive the protective cover 43, the adjusting rod 42, the underwater camera 41 and the transparent plate 45 to move through the electric push rod 47 and the positioning rod 46, realizing the lifting adjustment of the use height of the underwater camera 41. When the use direction needs to be adjusted, the motor 53 is started, so that the output end of the motor 53 drives the reducer 54 to rotate. The rotation of the reducer 54 can drive the connecting ring 55 to rotate. The rotation of the connecting ring 55 can drive the hydraulic cylinder 56 to rotate. The rotation of the hydraulic cylinder 56 can drive the connecting plate 48 to rotate. The rotation of the connecting plate 48 can drive the protective cover 43, the underwater camera 41 and the transparent plate 45 to move through the electric push rod 47, the positioning rod 46 and the adjusting rod 42, facilitating the user to adjust the use of the underwater camera 41 and enhancing the shooting and monitoring effect of the underwater camera 41 during use, achieving the effect of image monitoring.

[0053] During use, when the water area is turbid and the light is insufficient, the intelligent light supplement device 61 can be activated. When the intelligent light supplement device 61 is activated, it can monitor and supplement light around the underwater camera 41, improving the image shooting and recognition effect of the underwater camera 41. At the same time, during use, according to the usage requirements, the electric telescopic rod 65 can be activated, so that the output end of the electric telescopic rod 65 pushes the transparent plate 45 to move. The movement of the transparent plate 45 can push the laser light supplement lamp 63 and the transparent box 64 to move. The movement of the laser light supplement lamp 63 and the transparent box 64 can adjust the light supplement at the bottom of the underwater camera 41, enhancing the shooting clarity effect of the underwater camera 41, facilitating the user to clearly observe the flow rate and flow direction of the water through the shooting screen. The transparent box 64 can provide transparent protection for the bottom of the laser light supplement lamp 63 during use. At the same time, when the transparent plate 45 moves, it can drive the adjustment rod 42 to move. The movement of the adjustment rod 42 can drive the underwater camera 41 to move, facilitating the user to adjust the usage position of the underwater camera 41. The adjustment rod 42 has two ends that can move telescopically following the transparent plate 45, enhancing the adjustment convenience during use.

[0054] During use, according to the usage requirements, an edible contrast agent is used. By activating the solenoid valve 74, the solenoid valve 74 is opened to connect the central pipe 73 and the storage tank 75. The contrast agent in the storage tank 75 can enter the interior of the central pipe 73 through the solenoid valve 74. After passing through the central pipe 73, the contrast agent enters the interior of the hose 72 and finally enters the nozzle 71 through the hose 72 and is sprayed out from the nozzle 71. After the contrast agent is sprayed out, it can improve the fluid recognition rate. The contrast agent can significantly enhance the visualization degree of the fluid in the flow rate and flow direction meter, making the originally difficult-to-observe fluid become more clearly visible, facilitating the image shooting and monitoring of the underwater camera 41.

[0055] During use, the sealing plate 81 can seal the bottom of the transparent plate 45 to prevent water from entering the protective cover 43 when the transparent plate 45 is adjusted, affecting the normal use of the underwater camera 41 inside the protective cover 43. At the same time, the waterproof column 82 can protect the outside of the electric push rod 47, enhancing the use safety of the electric push rod 47. The protective column 83 can protect the bottom of the motor 53. Under the sealing of the sealing ring 84, the motor 53 can have a stable transmission effect. The corrosion-resistant column 85 can protect the outside of the hydraulic cylinder 56 against corrosion, preventing the hydraulic cylinder 56 from being damaged due to external corrosion, enhancing the use effect of the flow rate and flow direction meter.

[0056] In summary, for the flow velocity and direction meter based on image recognition, by setting up the image monitoring mechanism 4 and cooperating with the movable adjustment mechanism 5 to adjust the image recognition and monitoring in the water area, and at the same time adjusting the supplementary lighting mechanism 6 and the conveying contrast agent mechanism 7, the image monitoring effect of the image monitoring mechanism 4 can be effectively improved. The protection and sealing mechanism can effectively seal and protect the image monitoring mechanism 4 and the movable adjustment mechanism 5, solving the problem that the existing flow velocity and direction meters cannot effectively collect the image information of the water body, various characteristics, objects, forms, positions, etc. in the water body during monitoring and use. This results in the difficulty of accurately measuring the flow velocity and direction of the flow velocity and direction meter in the case of overly clear or overly turbid water bodies and small contrast of monitoring images, and can only rely on data to judge the flow velocity and direction, which is prone to misjudgment or difficult to accurately grasp the actual situation of the water flow, causing inconvenience in use and reducing the use effect of the flow velocity and direction meter.

[0057] Based on the above flow velocity and direction meter based on image recognition, the embodiment of the present invention also proposes a control method for a flow velocity and direction meter. Exemplarily, the control method includes:

[0058] Move the image monitoring mechanism, the movable adjustment mechanism, the adjustment supplementary lighting mechanism, the conveying contrast agent group and the sealing and protection mechanism to the water area to be monitored following the underwater detector;

[0059] By starting the movable adjustment mechanism, the movable adjustment mechanism can be started to move and adjust the use position of the image monitoring mechanism according to the use requirements;

[0060] Start the image monitoring mechanism, and the image monitoring mechanism starts to monitor and recognize the surrounding images, and transmits the monitoring data to the display through the integrated cable for display;

[0061] Start the adjustment supplementary lighting mechanism, and the adjustment supplementary lighting mechanism starts to adjust the supplementary lighting around the image monitoring mechanism to improve the effective monitoring effect of the image monitoring mechanism;

[0062] Start the conveying contrast agent mechanism according to the use requirements, and the conveying contrast agent mechanism starts to convey the contrast agent around to further improve the image monitoring effect of the image monitoring mechanism;

[0063] The sealing and protection mechanism can seal and protect the image monitoring mechanism and the movable adjustment mechanism, ensuring the normal operation of the image monitoring mechanism and the movable adjustment mechanism.

[0064] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
