Description

Technical Field

[0001] This invention relates to the field of fish migration channel technology, specifically a fish passage observation chamber structure. Background Technology

[0002] While water conservancy and hydropower projects play their role in flood control, power generation, and navigation, they also have a significant impact on the ecological environment, especially on the obstruction of fish migration channels. Fish passage facilities, as a fish protection measure to alleviate the obstruction effect of dams, have been used internationally for more than 300 years. The main types include fish passages, fish lifts, lifting gates, and fish collection and transportation systems. Existing fish monitoring solutions often involve setting up observation chambers directly on the side wall of fish passages to observe migrating fish. However, due to the large number of fish and their varying swimming speeds, as well as the mixing of different species, this method of setting up observation chambers directly in the fish passages can result in significant counting errors and makes it difficult to separately count and measure the number of fish species that are unevenly distributed.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0004] The purpose of this invention is to provide a fish passage observation chamber structure to solve the problems mentioned in the background art regarding the large counting error and difficulty in counting and measuring the unevenly distributed fish species in the fish passage observation method.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A fishway observation chamber structure includes: The migration unit includes a migration channel, an observation chamber body interspersed between the migration channels, and a counting probe located above the observation chamber body for photographing and recording the number and species of fish. The observation chamber unit includes a pre-blocking assembly, comprising a first baffle net located at the fish inlet of the observation chamber body for controlling fish to enter the observation chamber body and a second baffle net located at the fish outlet of the observation chamber body for controlling fish to swim out of the observation chamber body.

[0006] Furthermore, a second rotating shaft is fixedly connected to the lower end of the first baffle. The lower end of the second baffle is fixedly connected to the first rotating shaft: A first push rod is fixedly connected to the upper end of the first rotating shaft and located on the outside of the observation chamber body; A second push rod is fixedly connected to the upper end of the second rotating shaft and located on the outside of the observation chamber body; A connecting rod is hinged at the upper part between the first push rod and the second push rod, which is used to drive the first push rod and the second push rod to rotate synchronously.

[0007] Furthermore, a hinge rod is fixedly connected to one side of the first push rod; A first cylinder is installed on the outside of the main body of the observation chamber and at one end of the hinge rod. The drive end of the first cylinder is hinged to one end of the hinge rod.

[0008] Furthermore, a slide is installed at one end of the observation chamber body located on the first cylinder; The first cylinder is slidably connected to the outside of the slide rail.

[0009] Furthermore, a first baffle is fixedly connected to the upper side of the fish inlet end of the first baffle net to block the fish inlet end during the fish release process of the observation chamber body. A second baffle is fixedly connected to one side of the fish outlet end of the second baffle net, which is used to block fish from entering the observation chamber body.

[0010] Furthermore, a fish passage is fixedly connected to the bottom wall of the observation chamber body; The fish passage is provided in multiple sets at equal intervals to allow multiple fish to swim separately; The counting probe is suspended directly above the fish passage via the first crossbeam.

[0011] Furthermore, the observation chamber unit also includes a deflection assembly; The driving-away component includes: The second crossbeam is fixedly connected to the upper end of the observation chamber body and located on one side of the first crossbeam; The second cylinder is installed at the lower middle of the second crossbeam; A splashing plate, installed at the output end of the second cylinder, is used to splash water inside the observation chamber and drive away fish inside the observation chamber. The splashing plate is located between the first baffle net and the fish passage.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention first rotates a first baffle net towards the fish-entry end of the observation chamber, so that the upper end of the first baffle net is below the water surface. Fish swim along the migration channel past the upper end of the first baffle net and enter the observation chamber. Subsequently, the fish swim towards the second baffle net within the observation chamber. During this process, a counting probe counts and measures the fish swimming directly below. Then, the second baffle net is opened, allowing the fish that have completed the counting and measurement to swim out of the observation chamber, thus completing one round of counting and measurement. Throughout the entire counting and measurement process, no additional fish enter the observation chamber, resulting in high accuracy in the counting and measurement. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figures 1-5 The present invention provides a technical solution: A fishway observation chamber structure includes: The migration unit 1 includes a migration channel 11 and an observation chamber body 12 inserted between the migration channels 11, as well as a counting probe 15 located above the observation chamber body 12 for taking pictures and recording the number and species of fish. The observation chamber unit 2 includes a pre-blocking assembly 21, which includes a first baffle net 217 located at the fish inlet of the observation chamber body 12 for controlling fish to enter the observation chamber body 12 and a second baffle net 218 located at the fish outlet of the observation chamber body 12 for controlling fish to swim out of the observation chamber body 12.

[0017] It should be noted that when counting and measuring fish, the first baffle net 217 is first rotated towards the fish-entry end of the observation chamber 12, so that the upper end of the first baffle net 217 is lower than the water surface. After the fish swim along the migration channel 11 past the upper end of the first baffle net 217, they enter the observation chamber 12. Then, the fish swim towards the second baffle net 218 inside the observation chamber 12. During this process, the counting probe 15 counts and measures the fish swimming directly below. Then, the second baffle net 218 is opened, so that the fish that have been counted and measured swim out of the observation chamber 12, completing one round of counting and measurement. During the entire counting and measurement process, no additional fish enter the observation chamber 12, and the counting and measurement accuracy is high.

[0018] As an improvement, such as Figure 2 As shown, a second rotating shaft 216 is fixedly connected to the lower end of the first baffle 217; The lower end of the second baffle 218 is fixedly connected to the first rotating shaft 214. A first push rod 2141 is fixedly connected to the upper end of the first rotating shaft 214 and located on the outside of the observation chamber body 12; A second push rod 2161 is fixedly connected to the upper end of the second rotating shaft 216 and located on the outside of the observation chamber body 12; A connecting rod 215 is hinged at the upper part between the first push rod 2141 and the second push rod 2161, which is used to drive the first push rod 2141 and the second push rod 2161 to rotate synchronously.

[0019] Furthermore, such as Figures 1-2 As shown, a hinge rod 213 is fixedly connected to one side of the first push rod 2141; A first cylinder 211 is installed on the outside of the observation chamber body 12 and at one end of the hinge rod 213; The driving end of the first cylinder 211 is hinged to one end of the hinge rod 213.

[0020] Furthermore, a slide rail 212 is installed at one end of the observation chamber body 12 located on the first cylinder 211; The first cylinder 211 is slidably connected to the outside of the slide rail 212.

[0021] Among them, a first baffle 2171 is fixedly connected to the upper side of the fish inlet end of the first baffle net 217, which is used to block the fish inlet end of the observation chamber body 12 during the fish release process. A second baffle 2181 is fixedly connected to one side of the fish outlet end of the second baffle 218, which is used to block fish from entering the observation chamber body 12 during the fish entry process.

[0022] As an improvement, such as Figures 3-5As shown, the bottom wall of the observation chamber body 12 is fixedly connected to the fish passage 13; The fish passage 13 is provided with multiple sets at equal intervals to allow multiple fish to swim separately; The counting probe 15 is suspended directly above the fish passage 13 via the first crossbeam 14.

[0023] Furthermore, such as Figure 5 As shown, the observation room unit 2 also includes a deflection assembly 22; The driving-away component 22 includes: The second crossbeam 221 is fixedly connected to the upper end of the observation chamber body 12 and located on one side of the first crossbeam 14; The second cylinder 222 is installed at the lower middle of the second crossbeam 221; The water-slapping plate 223 is installed at the output end of the second cylinder 222 and is used to slap the water in the observation chamber body 12 and drive away the fish in the observation chamber body 12. The water-slapping plate 223 is located between the first baffle net 217 and the fish passage 13.

[0024] It should be noted that: in the specific implementation process of this invention, such as Figures 1-4 As shown, fish swim along the extension direction of the migration channel 11. When counting and measuring the fish, the first cylinder 211 is activated. The first cylinder 211 pushes the connecting rod 215 to move through the hinge rod 213. The connecting rod 215 drives the first push rod 2141 and the second push rod 2161 to rotate synchronously. This causes the first push rod 2141 to drive the first rotating shaft 214 to rotate. The first rotating shaft 214 drives the second baffle 218 and the second baffle 2181 to rotate. At the same time, the second rotating shaft 216 drives the first baffle 217 and the first baffle 2171 to rotate. During this process, the intersection line of the first baffle 2171 and the first baffle 217 is located below the water surface inside the observation chamber body 12, while the second baffle 2181 is above the water surface inside the observation chamber body 12. This allows the fish to swim into the interior of the observation chamber body 12 with the water flow in the migration channel 11, thus completing the fish entry process. like Figure 5As shown, the fish then swim towards the second baffle 218 within the observation chamber 12. During this process, the counting probe 15 counts and measures the fish swimming directly below. Then, by controlling the first cylinder 211 to pull the hinge rod 213, the hinge rod 213 synchronously drives the first push rod 2141 and the second push rod 2161 to rotate via the connecting rod 215. The first push rod 2141 drives the second baffle 218 and the second baffle 2181 to rotate in reverse via the first rotating shaft 214. At the same time, the second push rod 2161 drives the first baffle 218 to rotate in reverse via the second rotating shaft 216. 17. The first baffle 2171 is reversed, so that the intersection line of the second baffle 2181 and the second baffle net 218 is lower than the water surface inside the observation chamber body 12, while the first baffle 2171 is higher than the water surface inside the observation chamber body 12. This prevents fish from entering the observation chamber body 12 temporarily, and the fish that were previously counted inside the observation chamber body 12 swim out from inside the observation chamber body 12 above the intersection line of the second baffle 2181 and the second baffle net 218, ensuring that no additional fish enter the observation chamber body 12 during the entire counting and measurement process, and the counting and measurement accuracy is high. like Figure 5 As shown, in addition, the present invention ensures that different types of fish are separated by fish passages 13 at equal intervals at the bottom of the observation chamber body 12, and ensures that the fish swim below the counting probe 15 and remain evenly distributed, so that the counting probe 15 can count and measure different types of fish. like Figures 4-5 As shown, in order to prevent individual fish from lingering inside the observation chamber 12 for an extended period during the fish discharge process, the second cylinder 222 can be activated. The second cylinder 222 drives the water-slapping plate 223 to repeatedly rise and fall, causing the water-slapping plate 223 to repeatedly slap the water inside the observation chamber 12 near the first baffle 217. This ensures that the fish can swim out in a timely manner after being counted and measured in the observation chamber 12, thus improving the efficiency of the counting and measurement.
