Description

Technical Field

[0001] The invention belongs to the technical field of fish school monitoring, and in particular relates to an integrated buoy device for underwater fish water quality monitoring. Background Art

[0002] Fish monitoring equipment is a tool used to track and identify fish in the water in real time, including sonar, cameras and sensors. Its main function is to monitor the species, quantity and distribution of fish, collect ecological data to support fishery management and environmental protection, and provide a scientific basis for sustainable fishery development. At the same time, in the process of monitoring fish schools, monitoring water quality is also an important link, and the impact of water quality can have a greater impact on fish schools.

[0003] The Chinese patent application number 201510357154.0 discloses a buoy station for online monitoring of water environment, which solves the problem of the lack of effective protection of components in existing buoy stations. The buoy station for online monitoring of water environment includes an instrument cabin, at least one detection cabin and an equipment bracket. The instrument cabin is a conical sealed container with a small end facing downward. The detection cabin is connected to the instrument cabin and the lower end of the detection cabin extends out of the lower end of the instrument cabin. The equipment bracket is fixed to the upper end of the instrument cabin. The upper end of the equipment bracket has an anti-collision plate. The monitoring, communication, warning, security and other components are respectively located directly above or directly below the anti-collision plate. The vertical projection of the anti-collision plate to the upper end surface of the instrument cabin is located inside the upper edge of the instrument cabin. The buoy station for online monitoring of water environment can protect various components when hit by floating bodies such as ships to avoid damage caused by impact.

[0004] In the process of monitoring fish schools, how to monitor the real-time water quality at the same time can have positive significance for the study of fish activities. However, when a large number of fish are concentrated, although this area is convenient for monitoring fish activities, the excessive concentration of fish leads to more feces, a sharp drop in oxygen content and other problems, resulting in abnormal water quality monitoring, which does not represent the water quality of the entire water body, resulting in greater monitoring interference. When conducting fish monitoring, how to ensure the water quality monitoring situation has become a research focus. At the same time, how to protect the monitoring equipment from the influence of fish schools during the monitoring process is also necessary. Summary of the invention

[0013] Furthermore, when the adjustment cylinder is located at the upper half of the protective net cylinder, the torsion spring is in a torsion state, and the soft bristles of the brush plate abut against the mesh holes.

[0014] In a step, a fixing ring plate is extended outward from the upper end of the protection net tube, and the fixing ring plate is fixedly connected to the annular floating block by bolts.

[0015] Furthermore, the first monitoring ring block and the lower end of the protective net tube are in the same horizontal plane; and wire holes are provided on the upper side and the lower side of the support rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention controls the support rod to rise or fall by an electric telescopic rod, thereby adjusting the fish or water quality monitoring and avoiding monitoring interference. Specifically, when there are no large numbers of fish, water quality monitoring is mainly performed. At this time, the support rod is controlled to rise by the electric telescopic rod so that the adjustment tube is located in the upper half of the protective net tube. At this time, the water body enters the upper part of the first monitoring ring block through the mesh, so that the detection head monitors the water quality of the water body in real time. At this time, the waterproof camera plays a role in assisting the monitoring of fish schools. When there are a large number of fish around the equipment and it is not suitable for real-time water quality monitoring, the support rod is controlled to fall by the electric telescopic rod so that the adjustment tube is located in the lower half of the protective net tube. At this time, the closed ring and the first monitoring ring block are sealed and fitted, and the outer wall of the adjustment tube blocks all the meshes, so that the external instantaneous turbid water body will not enter the upper part of the first monitoring ring block in large quantities, so that the monitoring of the detection head will not be disturbed by sudden situations, resulting in abnormal monitoring data. At the same time, due to the descent of the support rod, the waterproof camera can be lowered to a position without line of sight obstruction, thereby playing a role in mainly monitoring fish schools, realizing comprehensive adjustment of fish or water quality monitoring and avoiding monitoring interference.

[0022] (2) When the present invention is mainly used for water quality monitoring, the driving rod is controlled to rotate back and forth periodically by controlling the forward and reverse motors, so that the rotating ring and the adjusting tube fixed thereto can be periodically rotated forward and reversed. Since the soft bristles of the brush plate abut against the mesh at this time, the soft bristles will continuously clean the mesh during the periodic forward and reverse rotation of the adjusting tube to prevent the mesh from being blocked, thereby avoiding abnormal monitoring of water quality. At the same time, the rotation of the brush plate can drive away fish to a certain extent and prevent the waterproof camera from being damaged by the fish. When there are a large number of fish around the equipment and it is necessary to switch to monitoring the activities of the fish, the brush plate will extend out of the protective net tube after the electric telescopic rod controls the support rod to descend. Under the reset of the torsion spring, the brush plate will flip upward at a certain angle, not only withdrawing from the monitoring viewing angle of the waterproof camera, which is beneficial to fish monitoring, but also through the continued forward and reverse rotation of the forward and reverse motors, the brush plate will continue to rotate to drive away the fish, preventing the fish from getting too close and damaging the waterproof camera.

[0023] (3) The present application adopts the structural design of the bracket. Since one end of the L-shaped connecting frame is fixedly connected to the mounting groove on one side of the middle pole by bolts, and the other end of the L-shaped connecting frame is fixedly connected to the mounting groove on the inner side of the support frame by bolts, the two middle poles can be adjusted laterally by loosening the bolts, moving the middle pole and then fixing it; similarly, through the connection relationship between the vertical pole and the middle pole and the horizontal pole, the position of the vertical pole on the middle pole can be adjusted, which not only facilitates the flexible installation and disassembly of the bracket, but also allows the center of gravity of the control box to be quickly changed, so that it can be quickly adjusted according to actual conditions, thereby improving the stability of the monitoring equipment in the water body; the present application adopts the connection relationship between the C-shaped connecting frame and the vertical pole, so that the control box can be adjusted up and down in height, thereby changing the height of the center of gravity of the monitoring equipment, thereby meeting the monitoring needs of water bodies of different depths and further improving the stability of the equipment in different monitoring environments.

[0035] Example

[0036] like Figure 1 to Figure 7As shown, an integrated buoy device for underwater fish water quality monitoring includes an annular floating block 100, a bottom plate 500 is fixedly installed at the bottom middle opening of the annular floating block 100, a bracket 200 is fixedly connected to the top of the bottom plate 500, a control box 400 and a solar panel 300 are installed on the bracket 200, a monitor is arranged in the control box 400, and the monitor is electrically connected to the solar panel 300; a protective net cylinder 600 is fixedly installed at the bottom middle opening of the annular floating block 100; a first monitoring ring block 120 is also fixedly connected to the bottom of the annular floating block 100 through two connecting rods 110, and a detection head 130 is installed on the first monitoring ring block 120; the first monitoring ring block 120 is located in the protective net cylinder 600;

[0037] An electric telescopic rod 510 is also fixedly installed at the bottom of the base plate 500, and the telescopic end of the electric telescopic rod 510 is fixedly connected to one end of the support rod 800, and the interior of the support rod 800 is a hollow structure; the support rod 800 passes through the first monitoring ring block 120 and the end is fixedly connected to the second monitoring ring block 830, and the second monitoring ring block 830 is installed with a waterproof camera 840; the detection head 130, the waterproof camera 840 and the corresponding monitor are electrically connected.

[0038] The present invention uses a solar panel 300 to power the monitor of the control box 400. Under the buoyancy of the annular floating block 100, the underwater water quality is monitored by the detection head 130, and the underwater fish activities are monitored by the waterproof camera 840. The present invention controls the support rod 800 to rise or fall through the electric telescopic rod 510, thereby adjusting the fish or water quality monitoring and avoiding monitoring interference, which will be described in detail later.

[0039] It is worth noting that the monitor and the detection head 130 of the present invention can detect the water quality of the water body, and the waterproof camera 840 can monitor the activity of the fish school by taking photos and videos, which are existing technologies and will not be described in detail here. The electric telescopic rod 510 can also be powered by the solar panel 300 or an external battery.

[0040] Further, the inner wall of the protective net cylinder 600 is movably fitted with an adjustment cylinder 700, and the height of the adjustment cylinder 700 is half of the protective net cylinder 600; the top of the adjustment cylinder 700 is fixedly connected with an adjustment frame 710, and the middle of the adjustment frame 710 is fixedly provided with a swivel 720; the upper side of the support rod 800 is fixedly provided with a limit ring groove 820, and the swivel 720 is sleeved in the limit ring groove 820 and rotatably connected with the limit ring groove 820; the upper half side wall of the protective net cylinder 600 is a closed structure, and the lower half side wall of the protective net cylinder 600 is evenly provided with a plurality of mesh holes 610. The mesh holes 610 have the ability to intercept some impurities to prevent inaccurate monitoring data.

[0041] Specifically, when there are no large numbers of fish, water quality monitoring is mainly used. At this time, the electric telescopic rod 510 is used to control the support rod 800 to rise, so that the adjustment cylinder 700 is located in the upper half of the protective net cylinder 600; at this time, the water body passes through the mesh 610 and enters the upper part of the first monitoring ring block 120, so that the detection head 130 monitors the water quality of the water body in real time. At this time, the waterproof camera 840 plays a role in assisting the monitoring of fish schools;

[0042] Furthermore, a closed ring 750 is extended inward from the bottom of the adjustment cylinder 700, and the inner diameter of the closed ring 750 is the same as the outer diameter of the first monitoring ring block 120; when the electric telescopic rod 510 controls the support rod 800 to descend and makes the closed ring 750 fit the outer side of the first monitoring ring block 120, the outer wall of the adjustment cylinder 700 blocks all the mesh holes 610.

[0043] When there are a large number of fish around the equipment, which is not suitable for real-time water quality monitoring, the electric telescopic rod 510 is used to control the support rod 800 to descend, so that the adjustment tube 700 is located in the lower half of the protective net tube 600. At this time, the closed ring 750 and the first monitoring ring block 120 are closed and fitted, and at the same time, the outer wall of the adjustment tube 700 blocks all the mesh holes 610, so that the external instantaneous turbid water will not enter the first monitoring ring block 120 in large quantities, so that the monitoring of the detection head 130 will not be disturbed by sudden situations, resulting in abnormal monitoring data; at the same time, due to the descent of the support rod 800, the waterproof camera 840 can be lowered to a position without line of sight obstruction, thereby playing a major role in monitoring fish schools, realizing comprehensive regulation of fish or water quality monitoring, and avoiding monitoring interference.

[0044] Furthermore, a rotating groove 821 is symmetrically opened in the limiting ring groove 820, and a driving rod 730 is penetrated in the rotating groove 821, and both ends of the driving rod 730 are fixedly connected to the inner side of the rotating ring 720; a forward and reverse motor 900 is fixedly installed on the upper part of the inner part of the support rod 800, and the output end of the forward and reverse motor 900 is fixedly connected to the driving rod 730.

[0045] It is worth noting that the forward and reverse motor 900 can also be operated by the solar panel 300; at the same time, the electric telescopic rod 510 and the forward and reverse motor 900 can be operated by a conventional external controller, such as a remote control switch, which will not be described in detail here.

[0046] Furthermore, a plurality of pairs of ear plates 742 are evenly fixedly provided at the bottom of the closed ring 750, each pair of ear plates 742 is rotatably connected with a rotating shaft 743, a brush plate 741 is fixedly connected to the rotating shaft 743, and soft bristles 745 are provided on the side of the brush plate 741 close to the protective net tube 600; a torsion spring 744 is sleeved on the rotating shaft 743 between the ear plate 742 and the brush plate 741, and the two ends of the torsion spring 744 are respectively fixedly connected to the ear plate 742 and the brush plate 741.

[0047] Furthermore, when the adjustment cylinder 700 is located at the upper half of the protection net cylinder 600 , the torsion spring 744 is in a torsion state, and the soft bristles 745 of the brush plate 741 abut against the mesh 610 .

[0048] When the present invention is mainly used for water quality monitoring, the forward and reverse motor 900 is controlled to periodically control the driving rod 730 to rotate back and forth, so that the rotating ring 720 and the adjusting cylinder 700 fixed thereto can be periodically reversed; because the soft bristles 745 of the brush plate 741 abut against the mesh 610 at this time, during the periodic forward and reverse rotation of the adjusting cylinder 700, the soft bristles 745 will continuously clean the mesh 610 to prevent the mesh 610 from being blocked, thereby avoiding abnormal monitoring of water quality. At the same time, the rotation of the brush plate 741 can drive away the fish to a certain extent, preventing The waterproof camera 840 is damaged by fish. When there are a large number of fish around the device and it is necessary to switch to monitoring the fish activities, the electric telescopic rod 510 controls the support rod 800 to descend, and the brush plate 741 will extend out of the protective net tube 600. Under the reset of the torsion spring 744, the brush plate 741 flips upward at a certain angle, which not only exits the monitoring field of view of the waterproof camera 840, which is beneficial for fish monitoring, but also continues to rotate the forward and reverse motor 900 to rotate the brush plate 741 to continue to drive away the fish, thereby preventing the fish from getting too close and damaging the waterproof camera 840.

[0049] Furthermore, since the waterproof camera 840 is disposed between the first monitoring ring block 120 and the second monitoring ring block 830 , the waterproof camera 840 is protected to a certain extent in space, thereby comprehensively improving the safety of the waterproof camera 840 .

[0050] It is worth noting that the rotation speed of the forward and reverse motor 900 of the present invention can be set to a slower speed to prevent the rotation speed from being too fast, causing the equipment to be unstable and affecting the monitoring.

[0051] Furthermore, a fixing ring plate 620 is extended outward from the upper end of the protection net tube 600 , and the fixing ring plate 620 is fixedly connected to the annular floating block 100 by bolts.

[0052] Furthermore, the first monitoring ring block 120 and the lower end of the protective net tube 600 are in the same horizontal plane; the upper and lower sides of the support rod 800 are both provided with wire holes 810. The wire holes 810 are used for passing wires to facilitate electrical connection.

[0053] Furthermore, four surfaces of each connecting rod of the bracket 200 are provided with mounting grooves; the bracket 200 includes a support frame 210 fixed to the top of the bottom plate 500, two middle rods 220 are provided in the support frame 210, and both ends of the middle rods 220 are provided with L-shaped connecting frames 230; one end of the L-shaped connecting frame 230 is fixedly connected to the mounting groove on one side of the middle rod 220 by bolts, and the other end of the L-shaped connecting frame 230 is fixedly connected to the mounting groove on the inner side of the support frame 210 by bolts;

[0054] Each of the middle poles 220 is provided with a vertical pole 240, the lower end of the vertical pole 240 is fixedly connected to the mounting groove on the top surface of the middle pole 220 through an L-shaped connecting frame 230 and bolts, and the upper end of the vertical pole 240 is fixedly connected to a cross pole 260 in the same way; both ends of the cross pole 260 are fixedly connected to the corresponding adjacent ends of the support frame 210 through an oblique pole 250;

[0055] A control box 400 is fixedly installed between the two vertical rods 240 , and a solar panel 300 is fixedly installed on the oblique rods 250 on the same side of the control box 400 .

[0056] The present invention adopts the structural design of the bracket 200. Since one end of the L-shaped connecting frame 230 is fixedly connected to the mounting groove on one side of the middle pole 220 by bolts, and the other end of the L-shaped connecting frame 230 is fixedly connected to the mounting groove on the inner side of the support frame 210 by bolts, the two middle poles 220 can be adjusted laterally by loosening the bolts and then moving the middle pole 220 and fixing it again; similarly, through the connection relationship between the vertical rod 240 and the middle pole 220 and the horizontal rod 260, the position of the vertical rod 240 on the middle pole 220 can be adjusted. This not only facilitates and flexibly installs and disassembles the bracket 200, but also quickly changes the center of gravity of the control box 400, so that it can be quickly adjusted according to actual conditions, thereby improving the stability of the monitoring equipment in the water body.

[0057] Furthermore, C-shaped connecting frames 280 are fixedly provided on both sides of the control box 400 , and both ends of the C-shaped connecting frames 280 are fixedly connected to the mounting grooves on the sides of the corresponding vertical rods 240 through bolts.

[0058] Through the connection relationship between the C-shaped connecting frame 280 and the vertical rod 240, the present invention can adjust the control box 400 up and down, thereby changing the up and down height of the center of gravity of the monitoring equipment, thereby meeting the monitoring requirements of water bodies at different depths and further improving the equipment stability in different monitoring environments.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
