Detailed Implementation

[0025] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] This utility model proposes an installation structure for an acoustic and optical monitoring device at the inlet of a fish collection trough for a fish lifter. This structure enables the installed acoustic and optical monitoring device to completely cover the inlet area of ​​the fish collection trough, achieving comprehensive monitoring of different water depths at the inlet area. Furthermore, the installed sonar monitoring device can adapt to changes in water level.

[0027] See Figure 1This utility model proposes an installation structure for an acoustic and optical monitoring device at the inlet of a fish collection trough for a fish lifter, including an acoustic sonar monitoring device mounting system 1 and an optical video monitoring device mounting system 2.

[0028] The acoustic sonar monitoring equipment system 1 is floatingly installed at the inlet of the fish collection tank; two optical video monitoring equipment systems 2 are provided, which are fixedly installed on the fish collection tank body and close to the inlet of the fish collection tank.

[0029] See Figure 2 The acoustic sonar monitoring equipment system 1 includes a vertical slide rail 11, a horizontal connector 12, a pulley 13, a buoy 14, a steel cable 15, and an anchor block 16.

[0030] On the inner sides of the fish collection tank inlet sidewalls 17 on both the left and right sides, vertical slide rails 11 are symmetrically fixedly installed. A buoy 14 is positioned at the transverse center of the vertical slide rails 11 on both sides. A transverse connector 12 is fixedly installed on each of the left and right sides of the buoy 14. The transverse connector 12 is preferably made of PVC pipe to reduce its weight. A pulley 13 is provided at the other end of the transverse connector 12, and the pulley 13 is slidably connected to the corresponding vertical slide rail 11. A steel cable 15 is suspended below the buoy 14, and an anchor block 16 is fixedly installed at the bottom of the steel cable 15. Several sonar monitoring devices 3 are fixedly installed at intervals along the water depth direction on the surface of the steel cable 15, for example, the sonar monitoring devices 3 are evenly spaced. Furthermore, depending on the shape of the sonar monitoring device 3, different methods such as clamp locking and nut fixing are used to fix the sonar monitoring device 3 to the steel cable 15. Furthermore, based on the width and depth of the fish collection tank inlet and the monitoring capability of the sonar monitoring equipment 3, the required number of sonar monitoring equipment 3 is determined.

[0031] The acoustic sonar monitoring equipment system 1 has the following advantages: the left and right ends of the buoy 14 are connected to the horizontal connecting member 12, and the other end of the horizontal connecting member 12 is connected to the pulley 13. The pulley 13 engages with the vertical slide rail 11. Therefore, through the action of the horizontal connecting member 12, the buoy 14 can be kept at the horizontal center position of the fish collection tank inlet. Furthermore, as the water level changes, the pulley 13 can slide freely up and down along the vertical slide rail 11, so that the buoy 14 adapts to the water level. Since the bottom of the buoy 14 is suspended by the anchor block 16 to maintain verticality, and multiple sonar monitoring devices 3 are installed at intervals on the steel cable 15, when the buoy 14 adapts to the water level, each sonar monitoring device 3 adapts to the water level, realizing the monitoring of different depth positions at the fish collection tank inlet. When the existing acoustic sonar monitoring equipment is exposed to air, it is prone to burn-out accidents. However, the sonar monitoring equipment of this application adapts to the water level, which can also solve the problem of easy burn-out and improve its safety of use.

[0032] See Figures 3 to 5 The optical video monitoring equipment mounting system 2 includes an H-shaped support frame 21, a bracket 22, and a frame 23;

[0033] The H-shaped support frame 21 can be made of stainless steel and includes two longitudinal main beams 211 arranged opposite each other and several cross beams 212 arranged between the two longitudinal main beams 211; wherein, the longitudinal main beams 211 and the fish collection tank side wall 24 can be anchored and fixed by fixing steel bars 25, and the fixing steel bars 25 are anchored to the fixing anchor points 26 of the fish collection tank side wall 24.

[0034] Several crossbeams 212 are arranged at intervals along the longitudinal direction, and each crossbeam 212 is welded and fixed to two longitudinal main beams 211 at both ends; the two longitudinal main beams 211 are fixed to the side wall 24 of the fish collection tank near the inlet of the fish collection tank.

[0035] The bracket 22 is fixedly installed on the outer side of each of the crossbeams 212; the frame 23 is fixedly installed on the outer side of each of the brackets 22; as shown Figure 5 As shown, mark 27 is the bracket welding point, which connects and fixes the bracket 22 and the frame 23. The frame 23 is made of stainless steel and is used to fix the camera unit 41. The frame 23 and the camera unit 41 constitute the optical video monitoring device 4, and are connected to the H-shaped support frame 21 through the bracket 22.

[0036] The optical video monitoring equipment equipped with system 2 has the following advantages:

[0037] An H-shaped support frame 21 is constructed using stainless steel, and brackets 22 corresponding to the number of optical video monitoring devices 4 are welded on them. The brackets 22 are then welded with frames 23, and each optical video monitoring device 4 is installed on the frames 23. The optical video monitoring devices 4 are welded to each frame 23 by stacking, so as to achieve full coverage of the monitoring area at the inlet of the fish collection tank.

[0038] This invention proposes an installation structure for an acoustic and optical monitoring device at the inlet of a fish-collecting trough for a fish lifter. The optical video monitoring device is welded to the frame of an H-shaped support structure using a stacking method, achieving complete coverage of the monitoring area at the inlet of the fish-collecting trough. A buoy, steel cable, and anchor block system is constructed to mount the acoustic sonar monitoring device, and pulleys and rails are used to connect the buoy to the sidewall, enabling the acoustic sonar monitoring device to adapt to water level changes and be positioned at the lateral center of the fish-collecting trough inlet. This invention allows the installed acoustic and optical monitoring device to completely cover the fish-collecting trough inlet area, achieving comprehensive monitoring at different water depths within the inlet area. Furthermore, the installed sonar monitoring device can adapt to water level changes.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
