Description

Technical Field

[0001] This invention relates to the field of fishway auxiliary technology, and in particular to a fishway monitoring system and its debris interception device. Background Technology

[0002] The construction of diversion dams will alter fish habitats, potentially leading to the extinction of certain migratory fish populations. Therefore, improving river connectivity, restoring river ecosystems, and providing greater protection for the aquatic environment have become urgent needs in the fields of aquatic ecology and water conservancy and hydropower engineering.

[0003] Fishways are structures built to facilitate fish migration. They are a measure to protect natural fishery resources, achieve biodiversity and sustainable development, and are the closest protective measure to the fish's natural habitat. The construction and operation management of fishways require extensive data collection, recording, and classification; analysis and processing of various complex fish passage situations; and continuous accumulation of experience and improvement of operational plans to achieve efficient fish passage and promote the development of the fishway construction industry. These tasks cannot be accomplished well through manual means and must be achieved with modern technology. Therefore, configuring a comprehensive and automated monitoring system is necessary.

[0004] Furthermore, among the many auxiliary devices for fishways, debris barriers are indispensable. These barriers are typically used to limit and block floating debris on the water surface, preventing it from entering the fishway, obstructing the fish, or even clogging it. However, current debris barriers generally use nets, which accumulate a large amount of floating debris on their surface over time. Some of this debris even enters the fishway through the bottom of the net, requiring regular manual cleaning. In practice, this makes the barriers not very practical. Summary of the Invention

[0005] In view of the problem that the existing technology cannot comprehensively monitor fishway data, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a fishway monitoring system.

[0015] The fish passage monitoring unit monitors the data from the image detection device and the counting detection device to accurately record the number of fish passing through the fish passage.

[0016] The beneficial effects of the fishway monitoring system of this invention are as follows: Through this fishway monitoring system, the overall data of the fishway can be monitored in real time and recorded directly. Thus, by studying the data, the scientific research level of personnel on fishways can be greatly improved.

[0017] In view of the fact that the prior art also mentions the problem of needing to manually clean floating objects at regular intervals, the present invention is proposed.

[0018] The present invention also provides a pollution interception device.

[0019] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a pollution interception device, comprising,

[0020] The backtracking mechanism includes a road, a baffle plate fixedly connected inside the road, and a mounting frame fixedly connected to the top of the road. The bottom end of the mounting frame has a through hole, and a protective shell is fixedly connected to the outside of the mounting frame. A drive component is adapted to be installed inside the protective shell.

[0021] The cleaning mechanism includes a support frame fixedly connected inside the mounting frame, a connecting block fixedly connected to one side of the support frame, and a rotating rod rotatably connected to the inner side of the connecting block.

[0025] In a preferred embodiment of the debris-blocking device of the present invention, the blocking component includes a baffle fixedly connected to one end of the guide plate, and an inclined plate fixedly connected to the bottom end of the baffle.

[0026] In a preferred embodiment of the pollution interception device of the present invention, the collecting component includes a roller shaft rotatably connected inside the mounting frame and a driven gear fixedly connected to the outside of the roller shaft. A reciprocating assembly is provided inside the roller shaft, a scraping assembly is provided on the outside of the roller shaft, and a limiting assembly is provided inside the roller shaft.

[0027] The reciprocating assembly includes a slide rod slidably connected inside the roller shaft, a protrusion fixedly connected to the outside of the slide rod, and a support rod fixedly connected to the outside of the slide rod, with a limit ball fixedly connected to one end of the support rod.

[0028] The outer side of the slide bar is provided with a connecting piece.

[0029] In a preferred embodiment of the debris-blocking device of the present invention, the connecting member includes a second hinge block fixedly connected to the outside of the slide bar, a first connecting rod hinged to the second hinge block, and a second connecting rod hinged to the first hinge block, wherein one end of the first connecting rod is connected to a ball joint at one end of the second connecting rod.

[0030] In a preferred embodiment of the debris-blocking device of the present invention, the scraping assembly includes an outer sleeve fixedly connected to the outside of the roller shaft, an inner rod slidably connected to the inside of the outer sleeve, and a slot formed on the outside of the inner rod.

[0031] As a preferred embodiment of the debris-blocking device of the present invention, the limiting component includes a mounting block fixedly connected inside the roller shaft, a guide rod slidably connected to the bottom end inside the mounting block, and a pressure rod slidably connected to the top end of the guide rod.

[0032] The guide rod is fitted with a second spring on its outer side, and the other end of the hinge rod is hinged to the pressure rod.

[0033] The beneficial effects of the debris-blocking device of the present invention are as follows: When the motor is started, it not only drives the roller to rotate and collect floating objects on the water surface, but also collects them when the inner rod rotates into the inside of the channel. This avoids the situation where the outer and inner rods would block the fish that are swimming back when they rotate into the inside of the channel, thus ensuring the safety of the fish passage. Furthermore, in conjunction with the swinging guide plate, baffle, and telescopic inner rod, the debris-blocking effect can be further improved, greatly enhancing the overall practicality of the device.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0047] Example 1

[0048] Reference Figure 9 This is the first embodiment of the present invention, which provides a fishway monitoring system, including,

[0049] Operation and management workstation A, data server B, monitor C, fishway auxiliary equipment monitoring unit D, and fishway fish passage monitoring unit E;

[0050] Among them, the operation management workstation A controls the monitoring unit D of the fishway auxiliary equipment to realize the operation of the fishway and display the screen on the monitor C;

[0051] By using the operation management workstation A to control the fish passage monitoring unit E, the monitoring of fish attraction, fish guidance and fish passage can be realized. Information on fish passage can be collected and analyzed. The fish passage monitoring video information can be displayed and played back through the monitor C, and finally the fish passage data can be managed.

[0052] The operation management workstation A transmits the images of fish passing through the fish passage, the number of fish passing through, the types of fish passing through, real-time meteorological environmental conditions, and real-time working status of the auxiliary equipment from the fish passage auxiliary equipment monitoring unit D and the fish passage fish passing monitoring unit E to the data server B for storage.

[0053] Specifically, the monitoring unit D for fishway auxiliary equipment mainly controls the fish-attracting light F, gate equipment G, spray equipment H, water replenishment equipment I, flow velocity sensor J, flow rate sensor K, water quality monitoring equipment L, water temperature monitoring equipment M, air temperature monitoring equipment N, air pressure monitoring equipment O, and debris-blocking equipment P;

[0054] The fish passage monitoring unit E mainly controls the image detection device Q and the counting detection device R.

[0055] Among them, the fishway auxiliary equipment monitoring unit D mainly controls the start and stop of the fish-attracting lamp F to attract fish, adjusts the water flow by controlling the gate device G, simulates precipitation by controlling the sprinkler device H, ensures that the inside of the fishway remains unchanged by controlling the water replenishment device I, monitors the data of the flow velocity sensor J, flow rate sensor K, water quality monitoring device L, water temperature monitoring device M, air temperature monitoring device N, and air pressure monitoring device O to ensure that all data meet the requirements of the fishway, and ensures the smooth flow of the fishway by controlling the debris barrier device P.

[0060] In summary, this fishway monitoring system allows for real-time monitoring and direct recording of the overall data of the fishway. By studying this data, researchers can significantly improve their understanding of fishways.

[0061] Example 2

[0062] Reference Figures 1-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a debris-blocking device, including...

[0063] The backtracking mechanism 100 includes a road 101, a baffle plate 102 fixedly connected inside the road 101, and a mounting frame 103 fixedly connected to the top of the road 101. A through hole 104 is provided at the bottom of the mounting frame 103. A protective shell 105 is fixedly connected to the outside of the mounting frame 103. A drive component 106 is adapted to be installed inside the protective shell 105.

[0064] The cleaning mechanism 200 includes a support frame 201 fixedly connected inside the mounting frame 103, a connecting block 202 fixedly connected to one side of the support frame 201, and a rotating rod 203 rotatably connected to the inner side of the connecting block 202. A guide plate 204 is rotatably connected to the outer side of the rotating rod 203. Extension plates 205 are fixedly connected to both sides of the guide plate 204. A first hinge block 206 is fixedly connected to the bottom end of the extension plate 205.

[0065] One end of the guide plate 204 is provided with a blocking component 207, the inside of the mounting frame 103 is provided with a collecting component 208, and the other side of the support frame 201 is designed with a slope.

[0066] Specifically, the drive component 106 includes a motor 106a disposed on the inner wall of the protective shell 105, a drive rod 106b fixedly connected to the output end of the motor 106a, and a drive gear 106c fixedly connected to one end of the drive rod 106b. A transmission assembly 106d is disposed on the outer side of the drive rod 106b.

[0067] Furthermore, the scraping assembly 208d includes an outer sleeve 208d-1 fixedly connected to the outside of the roller 208a, an inner rod 208d-2 slidably connected inside the outer sleeve 208d-1, and a slot 208d-3 opened on the outside of the inner rod 208d-2. A fixing block 208d-4 is fixedly connected to the outside of the inner rod 208d-2, and a first spring 208d-5 is sleeved on the outside of the inner rod 208d-2.

[0068] Preferably, the limiting assembly 208e includes a mounting block 208e-1 fixedly connected inside the roller 208a, a guide rod 208e-2 slidably connected to the bottom end of the mounting block 208e-1, and a pressure rod 208e-3 slidably connected to the top end of the guide rod 208e-2. A locking rod 208e-4 is slidably connected to the outside of the mounting block 208e-1, and a hinge rod 208e-5 is hinged to the outside of the locking rod 208e-4.

[0069] Among them, the outer side of the guide rod 208e-2 is fitted with a second spring 208e-6, and the other end of the hinge rod 208e-5 is hinged to the pressure rod 208e-3.

[0070] By starting the motor 106a, the motor 106a drives the drive rod 106b and the drive gear 106c at one end of the drive rod 106b to rotate. With the cooperation of the drive gear 106c and the driven gear 208b, the drive gear 106c drives the roller 208a to rotate through the driven gear 208b. The rotating roller 208a drives the outer sleeve 208d-1 and the inner rod 208d-2 to rotate, thereby collecting floating objects on the water surface and finally sending them into the mounting frame 103 through the guide plate 204, thus completing the collection of floating objects.

[0071] When the inner rod 208d-2 rotates to the inclined surface of the support frame 201, it will press against the inclined surface of the support frame 201. Under the action of the pressing force, the inner rod 208d-2 will slide into the inner surface of the outer sleeve 208d-1, and the fixing block 208d-4 will press against the first spring 208d-5, causing the first spring 208d-5 to contract. The upward sliding inner rod 208d-2 will press against the locking rod 208e-4, causing the locking rod 208e-4 to slide into the inner surface of the mounting block 208e-1. Due to the inclined design of the hinge rod 208e-5, the hinge rod 208e-5 will cause the guide rod 208e-2 to slide downward, and... The second spring 208e-6 is compressed, causing it to contract until the slot 208d-3 is located on the surface of the lever 208e-4. Under the elasticity of the second spring 208e-6, the guide rod 208e-2 and the lever 208e-4 will be reset, thereby causing the lever 208e-4 to insert into the slot 208d-3, thus limiting the inner rod 208d-2. By limiting the inner rod 208d-2 inside the outer sleeve 208d-1 in this way, it is possible to avoid obstructing the fish that are swimming back when the outer sleeve 208d-1 and the inner rod 208d-2 rotate into the interior of the passage 101, thus ensuring the safety of the fish passage.

[0072] In summary, when the motor 106a is started, it will not only drive the roller 208a to rotate and collect floating objects on the water surface, but also collect them when the inner rod 208d-2 rotates into the interior of the passage 101. This can prevent the outer sleeve 208d-1 and the inner rod 208d-2 from blocking the fish that are swimming back when they rotate into the interior of the passage 101, thus ensuring the safety of the fish passage.

[0073] Example 3

[0074] Reference Figure 7 and Figure 8 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a transmission assembly 106d including a disc 106d-1 fixedly connected to the outside of the drive rod 106b, and an annular guide groove 106d-2 opened on the outside of the disc 106d-1.

[0075] Specifically, the blocking component 207 includes a baffle 207a fixedly connected to one end of the guide plate 204, and an inclined plate 207b fixedly connected to the bottom end of the baffle 207a.

[0076] Furthermore, the collecting component 208 includes a roller 208a rotatably connected inside the mounting frame 103, and a driven gear 208b fixedly connected to the outside of the roller 208a. A reciprocating assembly 208c is provided inside the roller 208a, a scraping assembly 208d is provided on the outside of the roller 208a, and a limiting assembly 208e is provided inside the roller 208a.

[0077] The reciprocating assembly 208c includes a slide rod 208c-1 slidably connected inside the roller 208a, a protrusion 208c-2 fixedly connected to the outside of the slide rod 208c-1, and a support rod 208c-3 fixedly connected to the outside of the slide rod 208c-1. One end of the support rod 208c-3 is fixedly connected to a limit ball 208c-4.

[0078] Among them, the outer side of the slide bar 208c-1 is provided with a connecting piece 208c-5.

[0079] Preferably, the connector 208c-5 includes a second hinge block 208c-5a fixedly connected to the outside of the slide rod 208c-1, a first connecting rod 208c-5b hinged to the second hinge block 208c-5a, and a second connecting rod 208c-5c hinged to the first hinge block 206. One end of the first connecting rod 208c-5b is ball-jointed to one end of the second connecting rod 208c-5c.

[0080] The rotation of the drive rod 106b also drives the disk 106d-1 to rotate. Since the limiting ball 208c-4 is located inside the annular guide groove 106d-2, the rotating disk 106d-1 will drive the slide rod 208c-1 to slide back and forth. The slide rod 208c-1, through its reciprocating movement, will drive the first connecting rod 208c-5b and the second connecting rod 208c-5c to move back and forth, and push the guide plate 204 to rotate around the rotating rod 203. Since the first connecting rod 208c-5b and the second connecting rod 208c-5c are connected by a ball joint, the stable operation of the equipment can be ensured. The guide plate 204 rotates around the first connecting rod 203. Driven by the rod 208c-5b and the second connecting rod 208c-5c, the guide plate 204 swings back and forth. The swinging guide plate 204 not only increases the falling speed of the floating objects on the surface of the guide plate 204, preventing them from stopping on the surface of the guide plate 204 and causing blockage, but the guide plate 204 also drives the baffle 207a and the inclined plate 207b to swing back and forth. This can displace the floating objects intercepted on the surface of the baffle 207a, preventing the floating objects from continuously accumulating on the surface of the baffle 207a and causing some of the floating objects to enter the road 101 through the bottom of the baffle 207a, thereby further improving the overall pollution interception effect of the equipment.

[0081] As the slide bar 208c-1 slides back and forth, it causes the protrusion 208c-2 on the outer side of the slide bar 208c-1 to slide back and forth as well. When the retracted inner rod 208d-2 is about to rotate out of the inside of the road 101, the protrusion 208c-2 will press against the guide rod 208e-2, causing the locking rod 208e-4 to slide out of the slot 208d-3. With the elasticity of the first spring 208d-5, the inner rod 208d-2 will slide out of the outer sleeve 208d-1. This ensures that the floating objects intercepted by the baffle 207a can be collected a second time, and the process can be repeated to achieve a highly efficient pollution interception and cleaning effect.

[0082] In summary, when the motor 106a is started, it not only drives the roller 208a to rotate and collect floating debris from the water surface, but also collects the debris when the inner rod 208d-2 rotates into the interior of the passageway 101. This avoids blocking the fish that are swimming upstream when the outer sleeve 208d-1 and the inner rod 208d-2 rotate into the interior of the passageway 101, thus ensuring the safety of the fish passageway. Furthermore, in conjunction with the swinging guide plate 204, the baffle 207a, and the telescopic inner rod 208d-2, the debris-blocking effect can be further improved, significantly enhancing the overall practicality of the equipment.
