Abstract
Description
Technical Field
[0001] This invention relates to the field of water conservancy and hydropower engineering technology, and more specifically, to a residue collection device and a fishway system. Background Technology
[0002] In water conservancy and hydropower projects, fishways are key facilities for ensuring the passage of migratory fish and maintaining the ecological balance of the watershed, while fishway observation windows are core components for monitoring fish migration behavior and evaluating the effectiveness of fishway operation.
[0003] To ensure the transparency of the observation window, cleaning devices are typically used to wipe away contaminants and debris (such as algae debris, silt particles, and biological remains) from the fishway observation window using a reciprocating motion. However, the contaminants and debris generated by the cleaning devices can fall directly into the fishway water. On the one hand, they can easily accumulate at the bottom or in narrow areas of the fishway with the water flow, causing local blockages and affecting the normal migration of fish. On the other hand, the decomposition or diffusion of the debris in the water can increase water turbidity, consume dissolved oxygen, and even cause local water pollution, damaging the fishway's ecological environment. Summary of the Invention
[0004] The problem solved by this invention is how to prevent the residue cleaned from the observation window from affecting the fish passage.
[0005] To address the above problems, the present invention provides a residue collection device and a fishway system.
[0006] In a first aspect, the present invention provides a residue collection device, comprising: A flow guiding structure is provided below the observation window. The flow guiding structure includes a flow guiding component, which has a water inlet, a flow guiding channel, and a first water outlet connected in sequence. The flow guiding channel is arranged along the extending direction of the flow guiding component and is used to receive and guide the residue cleaned from the observation window. The water inlet is provided on the side wall of the flow guiding component, and the water inlet is used for the water flow from the fish passage to enter the flow guiding channel. A collection chamber structure is provided, which is installed on the concrete of the fishway; the collection chamber structure is provided with an inlet and a second outlet, the inlet is connected to the first outlet of the guide member, the collection chamber structure is used to collect the residue transported by the guide member, and the second outlet is used to connect to the fishway.
[0007] Optionally, the bottom wall of the flow guide channel of the flow guide is higher at the end near the observation window than at the end away from the observation window.
[0008] Optionally, the flow guide structure further comprises a flow guide plate, which is installed on the flow guide member at a position corresponding to the water inlet, and is arranged at an angle with the flow guide member.
[0009] Optionally, the flow guide structure further comprises a sealing strip, which is fixed on the side wall of the flow guide member at a position corresponding to the observation window.
[0010] Optionally, the inner wall of the flow guide channel is provided with an anti-sticking coating.
[0011] Optionally, the collection bin structure comprises a bin body, which is provided with the feeding port and the second water outlet, and is used to be detachably connected with the fishway concrete.
[0012] Optionally, the collection bin structure further comprises a mounting base, and the bin body is fixedly mounted on the fishway concrete through the mounting base.
[0013] Optionally, the collection bin structure further comprises a first magnetic attraction member and a second magnetic attraction member with opposite polarities, and the first magnetic attraction member and the second magnetic attraction member are respectively installed on the bin body and the mounting base.
[0014] Optionally, the collection bin structure further comprises a visual window, and a mounting port is formed in the side wall of the bin body, and the visual window is installed in the mounting port.
[0015] In the second aspect, the present application provides a fishway system, which comprises a fishway, an observation window and a residue collection device as described above, and further comprises a cleaning component, the observation window is installed on the fishway, and the cleaning component is used to clean the observation window.
[0016] The residue collection device and the fishway system have the following beneficial effects: The residue collecting device mainly comprises a guide structure and a collecting bin structure. Since the whole guide structure is arranged below the observation window, and the guide channel of the guide member is arranged along the extension direction of the guide member, in the process of cleaning the surface of the observation window, the residues on the surface of the observation window can be pushed into the guide channel as a whole, so that the residues are prevented from scattering into the water body of the fishway. Since the water inlet is arranged on the side wall of the guide member, the water flow of the fishway can smoothly enter the guide channel from the water inlet, and the flow of the water flow entering the guide channel can drive the residues to move towards the direction of the collecting bin structure. Since the feeding port of the collecting bin structure is communicated with the first water outlet of the guide member, the residues in the guide channel can be negatively pressed into the inside of the collecting bin structure by the negative pressure environment of the cavity structure of the collecting bin structure, so that the residues conveyed by the guide member can be collected through the backwater bin structure. Then, the clean water left after the residues are filtered in the collecting bin structure can be discharged from the second water outlet of the collecting bin structure into the fishway. In short, the self water flow of the fishway, the guide member and the collecting bin structure can be combined to generate negative pressure, so that the power device such as the water pump and the motor is not needed, thereby not only the energy consumption and the cost of the power device can be reduced, the efficient collection operation of the residues cleaned from the observation window without additional external force can be realized, the residues cleaned from the observation window are prevented from affecting the fishway and the water body, but also the interference of the power device operation to the fish migration is avoided, and the ecological protection requirement of the fishway is met.

[0023] In view of the problems in the above related technologies, the embodiments of the present application provide a residue collecting device and a fishway system.
[0024] As shown in Figures 1 to 3 The residue collecting device provided by the embodiments of the present application comprises: The flow guide structure 100 is arranged below the observation window 300, and the flow guide structure 100 comprises a flow guide piece 110 provided with a water inlet 111, a flow guide channel 112 and a first water outlet which are sequentially communicated, the flow guide channel 112 is arranged along the extension direction of the flow guide piece 110, and the flow guide channel 112 is used for receiving and guiding the residues cleaned from the observation window 300, and the side wall of the flow guide piece 110 is provided with the water inlet 111, and the water inlet 111 is used for guiding the water flow of the fishway 500 into the flow guide channel 112. The collection bin structure 200 is arranged on the fishway concrete, and the collection bin structure 200 is provided with a feeding port 211 and a second water outlet 212, the feeding port 211 is communicated with the first water outlet of the flow guide piece 110, the collection bin structure 200 is used for collecting the residues conveyed by the flow guide piece 110, and the second water outlet 212 is used for communicating the fishway 500.
[0025] Specifically, the observation window 300 can be arranged at the entrance area of the fishway 500, and whether the migratory fish can successfully find and enter the fishway entrance can be directly monitored, and the reaction of the fish to the water flow velocity at the entrance can be observed, whether there is hesitation, repeated impact or failure to enter.
[0026] The observation window 300 can also be arranged in the main body section inside the channel of the fishway 500, and the swimming posture, energy consumption and success rate of the fish when passing through the partition plate (such as vertical joint type, orifice type fishway) or climbing groove (such as Daniel fishway) can be directly observed.
[0027] The observation window 300 can also be arranged at the outlet area of the fishway 500, and the species, size, quantity and state (whether tired) of the fish which finally successfully enter the upstream water area can be recorded.
[0028] With respect to the entire flow guide piece 110 in Figure 1 The local structure of the flow guide piece 110 is embodied in Figure 2 The local structure of the flow guide piece 110 is embodied in Figure 2 The arrow in the flow guide channel indicates the moving direction of the residues pushed by the water flow.
[0029] The shape of the flow guide piece 110 along the cross section perpendicular to the flow direction of the water flow of the fishway 500 is a U-shaped structure. Along the flow direction of the water flow of the fishway 500, the flow guide piece 110 can be basically in an S-shaped structure.
[0030] The guide flow passage 112 of the guide flow member 110 can be a groove structure. The guide flow member 110 can be arranged below the observation window 300. The longer side wall top end of the guide flow member 110 can be attached to the lower edge of the observation window 300. During the cleaning process of the residues on the surface of the observation window 300 by the cleaning member 400, the residues can be smoothly pushed into or fall into the guide flow passage 112.
[0031] The water inlet 111 is arranged on the side wall of the guide flow member 110 away from the observation window 300. The water inlet 111 can be arranged at the end of the guide flow member 110 away from the collection bin structure 200. More water flow of the fishway 500 can enter the guide flow passage 112 from the water inlet 111.
[0032] At least part of the design of the guide flow member 110 needs to be completely matched with the wiping path of the cleaning member 400 (such as a cleaning strip or a cleaning brush). When the cleaning member 400 moves up and down or back and forth along the surface of the observation window 300, the end of the cleaning member 400 can always be attached to the inner wall of the guide flow passage 112. It is ensured that all the contaminants and residues generated during the cleaning process are pushed into the guide flow passage 112, so as to avoid the residues from scattering into the water body of the fishway 500.
[0033] The collection bin structure 200 can be a sealed cavity structure with a feeding port 211 and a second water outlet 212. Since the feeding port 211 of the collection bin structure 200 is in communication with the first water outlet of the guide flow member 110, a natural negative pressure environment can be formed in the interior of the collection bin structure 200.
[0034] In the embodiment, the residue collecting device mainly comprises a flow guide structure 100 and a collecting bin structure 200. Since the entire flow guide structure 100 is arranged below the observation window 300, and the flow guide channel 112 of the flow guide piece 110 is arranged along the extension direction of the flow guide piece 110, the residue on the surface of the observation window 300 can be pushed into the flow guide channel 112 as a whole during the process of cleaning the residue on the surface of the observation window 300, so as to avoid the residue from scattering into the water body of the fishway 500. Since the side wall of the flow guide piece 110 is provided with the water inlet 111, the water flow of the fishway 500 can smoothly enter the flow guide channel 112 from the water inlet 111, and the residue can be moved toward the direction of the collecting bin structure 200 by using the flow of the water flow entering the flow guide channel 112. Since the feeding port 211 of the collecting bin structure 200 is in communication with the first water outlet of the flow guide piece 110, the residue in the flow guide channel 112 can be negatively sucked into the inside of the collecting bin structure 200 by using the negative pressure environment of the cavity structure of the collecting bin structure 200, so as to collect the residue transported by the flow guide piece 110 through the backwater bin structure. Subsequently, the clean water left after the residue is filtered out in the collecting bin structure 200 can be discharged from the second water outlet 212 of the collecting bin structure 200 into the fishway 500. In short, the negative pressure can be generated by using the self water flow of the fishway 500, the flow guide piece 110 and the collecting bin structure 200, without the need of power devices such as water pumps and motors, so as to not only reduce the energy consumption and the cost of power devices, realize the efficient collection operation of the residue cleaned on the observation window 300 without additional external force, avoid the residue cleaned from the observation window 300 from affecting the fishway 500 and the water body, but also avoid the interference of the operation of the power devices to the fish migration, so as to meet the ecological protection requirements of the fishway 500.
[0035] Optionally, in combination with Figure 1 As shown in the figure, the height of the bottom wall of the flow guide channel 112 of the flow guide piece 110 near the observation window 300 is higher than the height of the end of the flow guide channel 112 away from the observation window 300.
[0036] Specifically, the end of the bottom wall of the flow guide channel 112 near the observation window 300 is higher than the end of the flow guide channel 112 away from the observation window 300, in other words, the bottom wall of the flow guide channel 112 is arranged to be inclined relative to the horizontal plane.
[0037] The bottom wall of the flow guide channel 112 can be provided with a certain slope, for example, 1% to 2%.
[0038] In the optional embodiment, the water flow of the fishway 500 can enter the flow guide channel 112 from the water inlet 111, so that the water flow in the flow guide channel 112 can be used to push the residues to move in the direction of the collection bin structure 200; since the bottom wall of the flow guide channel 112 is close to one end of the observation window 300 and is higher than the other end of the observation window 300, the residues in the flow guide channel 112 can flow in the direction of the collection bin structure 200 by relying on the slope of the bottom wall of the flow guide channel 112, thereby further improving the moving speed of the residues in the flow guide channel 112 and avoiding the accumulation of the residues in the flow guide channel 112.
[0039] Optionally, in combination with Figure 2 As shown in the drawings, the flow guide structure 100 further comprises a flow guide plate 120, which is installed on the flow guide piece 110 at a position corresponding to the water inlet 111, and the flow guide plate 120 is arranged at an angle with the flow guide piece 110.
[0040] Specifically, one end of the flow guide plate 120 can be fixedly connected with the outer side wall of the flow guide piece 110, and the other end of the flow guide plate 120 can be inclined toward the direction away from the flow guide piece 110.
[0041] The flow guide piece 110 can be arranged along the flow direction of the water flow of the fishway, and the flow guide plate 120 is arranged at an angle with the flow guide piece 110, so that the water flow in the flow guide channel and the water flow of the fishway outside the flow guide piece are basically in the same direction, which can prevent the water flow in the flow guide channel from flowing out of the water inlet in the opposite direction.
[0042] The flow guide plate 120 can adopt a plate structure such as an arc-shaped plate or a straight plate.
[0043] One end of the flow guide plate 120 and the flow guide piece 110 can be fixedly connected by means of one-piece forming or anchor bolt.
[0044] The flow guide plate 120, the flow guide piece 110 and the collection bin structure 200 can be made of stainless steel, so as to prolong the service life, and the collection bin structure 200 is made of stainless steel, which has the characteristics of resisting water body corrosion and avoiding harm to fish caused by dissolution of the material of the collection bin structure 200.
[0045] In the optional embodiment, since the flow guide plate 120 is installed on the flow guide piece 110 at a position corresponding to the water inlet 111, and the other end of the flow guide plate 120 is inclined toward the direction away from the flow guide piece 110, the flow rate of the water flow of the fishway 500 entering the flow guide channel 112 from the water inlet 111 is increased, the pushing speed of the residues in the flow guide channel 112 is further improved, the collection efficiency of the residues is correspondingly improved, and the accumulation of the residues in the flow guide channel 112 is avoided.
[0046] Optionally, in combination withFigure 2 and Figure 3 As shown in
[0047] Specifically, the sealing strip 130 can be made of flexible materials such as rubber, latex, etc. The sealing strip 130 can be fixed to the top end edge of the flow guide channel 112 of the flow guide 110 by clamping, fasteners, etc.
[0048] In this optional embodiment, the slot edge of the flow guide channel 112 is provided with a sealing strip 130, which is tightly fitted with the side surface of the cleaning component 400, so as to prevent residues from leaking out of the gap between the flow guide 110 and the cleaning component 400 during cleaning, further improving the sealing performance of residue collection.
[0049] Optionally, in combination with Figure 2 and Figure 3 As shown in
[0050] Specifically, the anti-sticking coating 140 can be a polytetrafluoroethylene coating, and the thickness can be controlled to be 0.1mm~0.5mm. The anti-sticking coating 140 can be formed on the inner wall of the flow guide channel 112 by spraying.
[0051] In this optional embodiment, by providing the anti-sticking coating 140 on the inner wall of the flow guide channel 112, the smoothness of the inner wall of the flow guide channel 112 of the flow guide 110 can be increased, and accordingly the residues adhering to the inner wall of the flow guide channel 112 can be reduced.
[0052] Optionally, in combination with Figure 1 As shown in
[0053] Specifically, the bin body 210 can be directly detachably installed on the fishway concrete, or indirectly detachably installed on the fishway concrete through other components.

When the residues in the bin body 210 reach a certain capacity, the maintenance personnel only need to apply an external force from the outside of the fishway 500 or the maintenance channel to remove the bin body 210 from the upper part of the fishway concrete, and then reinstall the bin body 210 on the fishway concrete after cleaning.
