Description

Technical Field

[0001] The invention relates to the technical field of fish passing facilities, and in particular to a convenient and efficient catapult-type fish collecting and transporting device and method suitable for low dams. Background Art

[0002] Humans have built dams and other river-blocking structures on rivers, which have destroyed the connectivity of rivers and blocked fish migration and spawning channels, resulting in a sharp decline in fish resources and a significant impact on river ecosystems. Fish migration is not only an important part of their life cycle, but also an important process for maintaining the ecological balance of rivers. Therefore, in order to reduce the obstacles to fish migration caused by dams, people have developed a variety of fish-passing facilities, including fishways and fish-collecting vessels, to help fish pass through river-blocking structures. However, these traditional facilities have the following major problems in practical applications: (1) Due to the large number of low dams and other river-blocking structures on rivers at home and abroad, if fishways or fish-collecting vessels are built for each structure, the construction and maintenance costs will be very huge and not economically feasible; (2) Traditional fish-passing facilities are less effective in attracting fish into the channels, and many fish find it difficult to find the path to enter the facilities, resulting in low fish-passing efficiency; (3) Existing facilities are not adaptable enough to different hydrological conditions. For example, the entrance of the fishway is fixed and cannot attract fish from different water layers and different regions to enter the fishway.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-7 As shown, a convenient and efficient catapult-type fish collecting and transporting device suitable for low dams includes a fish collecting and transporting pond chamber launching and storage system 2, wherein a fish collecting and transporting pond chamber 3 is arranged inside the fish collecting and transporting pond chamber launching and storage system 2, and a fish attracting channel 1 is arranged on one side of the fish collecting and transporting pond chamber launching and storage system 2, and a counterweight system 4 is arranged on the other side.

[0023] Preferably, a water spray pipe 11 for attracting fish and a sonar identification device 12 for identifying fish are provided in the fish-attracting channel 1. One end of the fish-attracting channel 1 is a fish inlet, and the other end is connected to the launching and storage system 2 of the fish collecting and transporting pond room.

[0024] Preferably, the collecting and transporting fish pond chamber launching and storage system 2 comprises a collecting and transporting fish pond chamber storage chamber 21, wherein a pushing device 22 for moving the collecting and transporting fish pond chamber 3 is provided in the collecting and transporting fish pond chamber storage chamber 21, and a first propeller 23 is provided on the outside of the collecting and transporting fish pond chamber storage chamber 21; a launching silo 24 is provided on the top of the middle area of ​​the collecting and transporting fish pond chamber storage chamber 21, a channel connected to the fish luring channel 1 is provided on the side of the collecting and transporting fish pond chamber storage chamber 21 close to the fish luring channel 1, and an ejection device 25 for launching the collecting and transporting fish pond chamber 3 is provided at the bottom of the collecting and transporting fish pond chamber storage chamber 21.

[0025] Preferably, a recycling port and a cover plate matched with the recycling port are provided on the top of the storage chamber 21 of the collecting and transporting fish pond room, and a solar power generation module 26 is provided on the upper surface of the cover plate. The pushing device 22 is an electric push rod or an electric telescopic rod structure, which is transversely arranged in the storage chamber 21 of the collecting and transporting fish pond room. In this embodiment, the pushing device 2 can push the collecting and transporting fish pond room 3 to move in the storage chamber 21 of the fish pond room, so that every time a collecting and transporting fish pond room 3 is ejected from the launch shaft port 24, the adjacent collecting and transporting fish pond room 3 can be pushed to the launch shaft port 24 by the pushing device 22 to prepare for the next ejection process.

[0026] Preferably, the ejection device 25 includes a base 251 fixedly connected to the bottom of the storage chamber 21 of the fish collection and transportation pond room, two rotating motors are arranged inside the base 251, the rotating shaft 252 of the rotating motor is connected to one end of the rotating rod 253, the other end of the rotating rod 253 is provided with a rotating motor, the rotating shaft 254 of the rotating motor is connected to one end of the pressure rod 255, the other end of the pressure rod 255 cooperates with the pressure groove of the ejection plate 256, the base 251 is fixedly connected to the bottom of the spring 257, and the top of the spring 257 is fixedly connected to the bottom of the ejection plate 256; the base 251 is also provided with a photoelectric sensor 258 for detecting the arrival position of the fish collection and transportation pond room 3, and the output end of the photoelectric sensor 258 is connected to the controller. In this embodiment, the ejection device adopts this spring ejection method. Since it is a low dam, the height difference is small, so this spring ejection method can be adopted. If the height difference is large, a method similar to electromagnetic ejection can also be adopted; the working principle of this ejection device in this embodiment is as follows: When the rotating motor is working, it drives the rotating rod 253 to rotate through the rotating shaft 252, so that the pressure rod 255 also performs a first-level pressing process on the ejection plate 256. Since the other end of the pressure rod 255 cooperates with the pressing groove of the ejection plate 256, the length of the pressing groove is long enough so that the pressure rod 255 can slide in the pressing groove during the pressing process; when the end of the rotating rod 253 is close to the edge of the ejection plate 256, the rotating motor stops working; then the rotating motor works and drives the pressure rod 255 to rotate through the rotating shaft 254 to perform a second-level pressing process; the pressure rod 255 rotates continuously until its end leaves the pressing groove, thereby releasing the pressure on the ejection plate 256, and the ejection plate 256 is ejected by the spring 257. Under the action of force, it moves upward, thereby driving the fish collecting and transporting pond chamber 3 to be ejected from the launching silo mouth 24; in this embodiment, the photoelectric sensor 258 can detect whether the fish collecting and transporting pond chamber 3 has accurately reached the position of the ejection plate 256. If there is a deviation in the position, it controls the pushing device 22 to act through the controller, thereby adjusting the position of the fish collecting and transporting pond chamber 3; in addition, the controller also controls the working process of the rotating motor and the rotating motor; in this embodiment, in order to avoid the interference or influence of the bottom of the fish collecting and transporting pond chamber 3 on the rotating rod 253 and the pressure rod 255, the bottom of the fish collecting and transporting pond chamber 3 and the position corresponding to the rotating rod 253 and the pressure rod 255 can be opened into a hollow structure to effectively solve this problem.

[0027] Preferably, an electric door 31 is provided on one side of the fish collection and transportation pond chamber 3 to match the end of the fish luring passage 1. The control end of the electric door 31 is connected to the output end of the controller, and the input end of the controller is connected to the sonar identification device 12. A second propeller 32 is provided on the outside of the fish collection and transportation pond chamber 3, and a protective frame 33 is provided on the periphery of the second propeller 32. The sonar identification device 12 can monitor the passage of fish; before the fish begin to arrive at the fish collection and transportation pond chamber 3, the controller controls the electric door 31 to open so that the fish can enter. When the amount of fish passing through reaches the set value, the controller controls the electric door 31 to close. In this embodiment, a plurality of sieve holes are provided on the surface of the fish collection and transportation pond chamber 3 to facilitate water flow through so that the fish can enter. At the same time, when ejected, the water flow will also escape to reduce its own gravity. In addition, in order to further reduce the weight of the fish collection and transportation pond chamber 3, a lightweight material that can float on the water surface can be selected to prevent it from sinking.

[0028] Preferably, the counterweight system 4 includes a counterweight box 41, and the side wall of the counterweight box 41 is provided with a water pump 42, a drainage pump 43, and a connected water inlet pipe and a water outlet pipe, and the counterweight box 41 is fixedly connected to the side of the launching and storage system 2 of the collecting and transporting fish pond room. In this embodiment, water can be introduced into the counterweight box 41 through the water pump 42, so that the weight of the counterweight system 4 is increased, and the whole device is tilted on the water surface, so that the launch well mouth 24 can be tilted and aligned with the upstream position of the low dam; and the water in the counterweight box 41 can be discharged through the drainage pump 43, so that the weight of the counterweight system 4 is reduced, so that the whole device is kept horizontal on the water surface again, which is convenient for the fish entering process.

[0029] Preferably, a camera 44 is also provided on the side of the counterweight box 41. The status of the fish school in the water can be observed through the camera 44. When a large number of fish schools are found in a certain area, the propeller of the device is controlled by the controller to move to the area, so that the position of the entire device on the water surface can be flexibly adjusted according to the distribution of the fish school, thereby ensuring the high efficiency of the fish passing efficiency.

[0030] The present invention also discloses a method for collecting and transporting fish using the convenient and efficient catapult-type fish collecting and transporting device suitable for low dams, which comprises the following steps: S1. The entire device is initially moved by its propeller and floats to the fish gathering area downstream of the low dam.

When the fish reaches the recognition area of ​​the sonar recognition device, the electric door of the fish collection and transportation pond room will be opened, and the fish enter the fish collection and transportation pond room. When the sonar recognition device detects that a certain number of fish enter the fish collection and transportation pond room, the electric door of the fish collection and transportation pond room will be closed. In this embodiment, the entire device has a certain weight. When it floats on the water surface, the fish luring channel is located below the water surface.

[0031] S2. When the electric door of the fish tank room is closed, the counterweight system extracts or discharges a certain amount of water through the water pump and the drainage pump, so that the center of gravity of the entire device is shifted and tilted at a certain angle. At this time, the launch well mouth faces the upstream direction of the low dam; S3, the ejection device in the launching and storage system of the fish collection and transportation pond room works, so that the fish collection and transportation pond room is ejected from the launch well mouth, and then reaches the upstream area of ​​the low dam. At this time, the propeller of the fish collection and transportation pond room works, so that the fish collection and transportation pond room moves on the water surface. After reaching the designated area, the electric door is opened to release the fish; S4. The pushing device in the launching and storage system of the transporting fish pond room pushes the other empty transporting fish pond room to the location of the launching well mouth, and then the electric door of the transporting fish pond room opens, and the fish enter the transporting fish pond room. When the sonar recognition device detects that a certain number of fish enter the transporting fish pond room, the electric door of the transporting fish pond room will be closed; S5, repeat steps S2, S3 and S4 until all the fish collection and transportation pond rooms for fish entering are launched.

[0032] Furthermore, it also includes S6: after the fish collecting and transporting pond chamber in step S3 is released, its propeller works to send the fish to the recovery area. In step S5, when all the fish collecting and transporting pond chambers with fish are launched, the propeller of the device also works to move it to the recovery area. The staff regularly reinstalls the fish collecting and transporting pond chambers in the recovery area into the device to realize the process of reuse.
