Description

Technical Field

[0001] This invention relates to the field of fish resource protection technology, specifically to an intelligent fish passage monitoring device. Background Technology

[0002] As a man-made ecological passage, the design of fishways to truly suit the target fish species cannot be judged solely by theory. Monitoring data is the "only report card" to verify their success. By statistically analyzing the number, species, size, and time of fish passage, we can directly assess whether the fishway has restored the longitudinal connectivity of the river and helped fish complete their migration. If the data is not ideal, it provides a direct basis for structural modifications or adjustments to the operation plan of the fishway. Generally, underwater cameras are installed to automatically mark and photograph fish schools in order to monitor the effectiveness of fish passage. The existing Chinese patent, application number 202410422390.5, entitled "A Fishway Monitoring Device," uses cameras to capture video of swimming fish from two mutually perpendicular directions and can identify situations where multiple fish overlap while swimming, solving the problem of low counting accuracy in traditional methods. Furthermore, infrared gratings are installed at both ends of the enclosure, ensuring stable fish counting even in turbid water, guaranteeing the reliability of the monitoring results. In addition, the design of the structure between the camera and the enclosure facilitates disassembly and installation, making equipment maintenance more convenient and significantly reducing operating costs. However, most existing underwater monitoring devices lack camera glass cover cleaning devices, which means that manual cleaning is required after a period of use. This is not only troublesome but also interrupts monitoring and affects data accuracy. To avoid the above technical problems, it is necessary to provide an intelligent fish passage effect monitoring device to overcome the defects in the existing technology. Summary of the Invention

[0011] Preferably, a fixing component is installed on the inner side of the spherical glass cover; The fixing component includes a fixing tube; A fixed tube is installed inside the rotating column. A monitoring camera is installed at one end of the fixed tube. A fixed slot plate is sleeved on the outside of the monitoring camera. A support frame is welded to the outside of the fixed slot plate. A counterweight is installed at the bottom of the fixed slot plate. A roller is rotatably installed on the inside of the support frame. A steel connecting rod is welded to the top of the cleaning cylinder. A limit block is threaded to the outer side of the top of the steel connecting rod. A stabilizing float is sleeved on the outer side of the steel connecting rod. A mounting plate is connected to one end face of the stabilizing float. A threaded groove is opened on the inner side of the mounting plate. A fixing screw is threaded to the inner side of the threaded groove.

[0012] Preferably, there are two fixing slots, which are symmetrically fitted onto the outer side of the monitoring camera.

[0013] Preferably, a height limiting groove is provided on the inner side of the stabilizing float, the steel connecting rod is slidably connected to the steel connecting rod through the height limiting groove, and the output end of the monitoring camera is electrically connected to the output end of the external controller.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. Equipped with a cleaning component, the pressure pump is activated to repeatedly flush the spherical glass dome. This cleans the originally dirty surface of the dome, and repeated flushing ensures that the surface of the dome remains clean, especially the side submerged in water. This guarantees that the monitoring camera can always clearly capture images of the fish in the fishway during fish monitoring, ensuring the accuracy of the data and allowing for accurate assessment of the impact of water conservancy projects on fish populations. This helps water conservancy engineers to continuously improve water conservancy projects and further optimize the ecological environment.

[0015] 2. It is equipped with a fixing component. Under the gravity of the counterweight, the support frame and the fixing slot plate will always fix the monitoring camera in the same position on the inner wall of the spherical glass cover, thereby ensuring the accuracy of the monitoring image and preventing the monitoring camera image from changing when the spherical glass cover is rotated for cleaning. This ensures that the monitoring camera will always shoot from the same position and that the monitoring image will not change. The mounting plate is moved to the installation point of the water conservancy project. The operator then passes the fixing screw through the threaded groove and tightens it into the expansion tube of the water conservancy project wall, thereby fixing the stabilizing float plate and ensuring that monitoring devices can be installed in fish passages of various sizes, thus ensuring the effectiveness of fish monitoring.

[0016] In summary, by repeatedly rinsing the spherical glass dome with the pressure pump, the previously dirty surface on the outside of the dome is cleaned. Multiple rinses ensure the dome's surface remains clean, alternating between clean and dirty areas. When fixing the fish monitoring device at different depths, prepare steel connecting rods of appropriate lengths. The operator inserts the steel connecting rod through the stabilizing float to its top position. Then, the operator tightens the limiting block to the top of the outer side of the steel connecting rod, thus securing the steel connecting rod and the bottom cleaning cylinder. The operator can then move the mounting plate to the installation point of the water conservancy project. This ensures that, regardless of the installation location, the monitoring camera can stably capture images and automatically mark various fish in the water. AI recognition distinguishes fish groups and counts their numbers, allowing operators to quickly and effectively analyze fish data accurately and improve the safety of the fish's habitat.

The output end of the monitoring camera 302 is electrically connected to the output end of the external controller.

[0023] The working principle and usage process of this invention: First, when the monitoring device is used in the fishway in the water conservancy project, a large amount of planktonic matter and algae will continuously attach to the outside of the spherical glass cover 207. Over a long period of time, these algae will block the image captured by the monitoring camera 302, thereby affecting the accuracy of the data. Every so often, the waterproof motor 205 inside the waterproof housing 204 is started, which drives the clamping plate 206 to rotate. The clamping plate 206 rotates at a constant speed inside the bearing 202 via the rotating column 203. Then, the clamping plate 206 drives the spherical glass cover 207 to rotate inside the sealed groove 208. When the spherical glass cover 207 rotates, the outer wall of the cleaning cylinder 1 first scrapes and cleans the outer wall of the spherical glass cover 207, thus performing preliminary cleaning of the spherical glass cover 207. Then, the side of the spherical glass cover 207 that needs to be cleaned rotates to the inside of the conversion chamber 219. Then, the pressurizing pump 215 is turned on, which allows external cleaning water to be introduced into the inside of the pressurizing pipe 216. Then, this water enters the internal position of the pressurized shower head 217. Then, this water is sprayed onto the spherical glass cover 207 at the bottom through the nozzle 218 at the bottom of the pressurized shower head 217. These high-pressure water jets continuously scour the outer wall of the spherical glass dome 207, washing away a large amount of algae and plankton. These debris are then washed into the annular water pipe 209. Simultaneously, the water pump 213 is activated, which extracts the sewage from the conversion chamber 219. This sewage enters the inner side of the annular water pipe 209 through the suction trough 210. Then, the sewage is transported to the inside of the connecting pipe 212 through the sewage pipe 211. Subsequently, the sewage enters the inside of the water pump 213 through the connecting pipe 212 and is discharged into the fish passage through the wastewater pipe 214, thus removing the debris. Next, the pressure pump 215 is turned on again to repeatedly flush the spherical glass cover 207. This cleans the originally dirty surface of the spherical glass cover 207. The repeated flushing cleans the outer surface of the spherical glass cover 207 alternately, keeping the side of the spherical glass cover 207 in the water clean. The high-pressure water flow continuously flushes the outer wall of the spherical glass cover 207, washing away a large amount of algae and plankton. These debris are flushed to the position of the annular water pipe 209. At the same time as flushing, the water pump 213 is turned on to pump out the sewage inside the conversion chamber 219, which can prevent secondary pollution from the sewage. This ensures that the monitoring camera 302 can always clearly capture the fish in the fish passage during fish monitoring, ensuring the accuracy of data monitoring and accurately assessing the impact of water conservancy projects on fish. This can help water conservancy engineers to continuously improve water conservancy projects and further optimize the ecological environment. Subsequently, as the spherical glass cover 207 rotates continuously, the roller 306 will continuously rotate against the inner wall of the spherical glass cover 207. Under the gravity of the counterweight 305, the support frame 304 and the fixing slot plate 303 will always fix the monitoring camera 302 in the same position on the inner wall of the spherical glass cover 207, thereby ensuring the accuracy of the monitoring image and preventing the image of the monitoring camera 302 from changing when the spherical glass cover 207 rotates for cleaning. This ensures that the monitoring camera 302 will always capture the same position and that the monitoring image will not change. Finally, when fixing the fish monitoring device to different depths, prepare steel connecting rods 307 of appropriate length. The operator inserts the steel connecting rod 307 through the stabilizing float 309 to the top position of the stabilizing float 309. Then, the operator can tighten the limiting block 308 to the outer top position of the steel connecting rod 307, thereby fixing the steel connecting rod 307 and the bottom cleaning cylinder 1. Subsequently, the operator can move the mounting plate 310 to the installation point of the water conservancy project. The operator passes the fixing screw 312 through the threaded groove 311 and tightens it into the expansion tube of the water conservancy project wall, thereby fixing the stabilizing float 309. This ensures that the monitoring device can be installed in fish passages of various sizes, thus ensuring the effectiveness of fish monitoring.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
