Abstract
Description
Technical Field
[0001] This invention belongs to the field of water conservancy and hydropower engineering, specifically relating to a fish box transfer device and transfer method that integrates inclined cable pulling and lifting. Background Art
[0002] Currently, fish protection measures at hydropower stations typically involve constructing fish passage facilities to allow fish to cross the dam, which usually require a fish transportation component. Given the often hundreds of meters of height required for transporting fish across steep inclines, overcoming this elevation difference necessitates the construction of extremely long roads or tunnels, resulting in lengthy transportation times. The construction costs of such long roads and tunnels are very high, and the extended transportation time also reduces the survival rate of the fish. Summary of the Invention
[0003] To address the challenge of enabling fish transport vehicles to handle steeper inclines and longer distances, this invention provides a fish box transfer device and method that integrates inclined pulling and lifting.
[0004] The object of the present invention is achieved in the following manner: a fish box transfer device integrating inclined pulling and lifting, including a track 22 fixed on a slope 21, a slope fish transport vehicle 1 is movably mounted on the track 22, and a lifting device 3 is provided at the upstream of the slope 21; The lifting equipment 3 includes a gantry structure 32, on which a fish box lifting and transfer mechanism 31 is slidably mounted. The fish box lifting and transfer mechanism 31 is used to grab the fish box 4 and place or remove it from the slope fish transport vehicle 1. The gantry structure 32 is also provided with a slope fish transport vehicle inclined pull winch mechanism 33, which is used to drive the slope fish transport vehicle 1 to move on the track 22.
[0005] Furthermore, the slope fish transport vehicle 1 includes a vehicle body 11, a motion mechanism 12 that cooperates with the track 22 is provided at the bottom of the vehicle body 11, and a horizontal support structure 13 is fixedly connected to the top of the vehicle body 11. The horizontal support structure 13 is a steel frame structure, and the top surface of the steel frame structure forms a horizontal support surface.
[0006] Furthermore, the gantry structure 32 includes a top gantry support plate 321 and a plurality of gantry columns 322 for supporting the gantry support plate 321. The fish box lifting and transfer mechanism 31 includes a slide rail 313 fixed to the bottom of the gantry support plate 321. The slide rail 313 is slidably fitted with a transfer mechanism 312. The bottom of the transfer mechanism 312 is provided with a fish box lifting mechanism 311.
[0007] Furthermore, the fish box lifting mechanism 311 includes a fish box gripping device 3112, which is connected to the bottom of the transfer mechanism 312 via a scissor lifting mechanism. It also includes a lifting winch mechanism 3111 fixed to the bottom of the transfer mechanism 312, which drives a steel wire rope suspending the fish box gripping device 3112.
[0008] Furthermore, the gantry structure 32 extends a cantilever structure toward the slope 21, and the slide rail 313 extends to the cantilever structure. The projection of the cantilever structure in the vertical direction covers the fish transport vehicle 1 on the slope located at the extreme position of the track 22.
[0009] Furthermore, the top of the gantry support plate 321 is fixedly connected to the inclined winch mechanism 33. The top of the gantry support plate 321 behind the inclined winch mechanism 33 is provided with a reversing pulley device 331. The gantry support plate 321 behind the reversing pulley device 331 is provided with a wire hole. Below the wire hole, near the top of the slope 21, a guide pulley device 332 is provided. The slope fish transport vehicle 1 is fixedly connected to the lifting lug structure 111. The inclined winch mechanism 33 is driven and connected to the winch wire rope 334. The winch wire rope 334 sequentially cooperates with the reversing pulley device 331, passes through the wire hole, cooperates with the guide pulley device 332, and is connected and fixed to the lifting lug structure 111.
[0010] Furthermore, a second lifting device is provided downstream of the slope 21. The second lifting device includes a gantry structure 32 and a fish box lifting and transfer mechanism 31 that is slidably mounted on the gantry structure 32.
[0011] The transfer method for the integrated inclined pull and lifting fish box transfer equipment described above includes the following steps: S1. After the fish box 4 collects the target fish from the fish collection stage, it is transported by the flat transfer vehicle 5 to the designated position within the span of the second lifting equipment, waiting for the fish box lifting and transfer mechanism 31 to grab the fish box 4. S2. After the fish box lifting mechanism 311 picks up the fish box 4, it lifts it to a specified height. After the fish box reaches the specified height, the fish box transfer mechanism 312 moves forward along the slide rail 313, driving the fish box lifting mechanism 311 and the fish box 4 forward to a specified position. Directly below the specified position is the stopped slope fish transport vehicle 1. The fish box lifting mechanism 311 lowers and places the fish box 4 on the horizontal support structure 13 of the slope fish transport vehicle 1. After the fish box 4 is placed, the inclined winch mechanism 33 on the lifting equipment 3 at the top of the slope is activated, and the fish transport vehicle 1 on the slope is pulled up along the track 22 by the winch wire rope 334. After reaching the designated position, the fish box lifting and transfer mechanism 31 of the lifting equipment 3, which is directly above the fish box 4, lifts the fish box 4 to the designated height. After the fish box 4 reaches the designated height, the fish box transfer mechanism 312 transfers the fish box 4 to the designated position and puts it down, completing the slope transfer work of the fish box 4.

Therefore, they should not be construed as limitations on the invention.
[0017] As attached Figure 1 , 3 As shown, the integrated inclined and lifting fish box transfer equipment includes a track 22 fixed on the slope 21, a slope fish transport vehicle 1 is mounted on the track 22, and a lifting device 3 is installed at the upstream of the slope 21. The lifting equipment 3 includes a gantry structure 32, on which a fish box lifting and transfer mechanism 31 is slidably mounted. The fish box lifting and transfer mechanism 31 is used to grab the fish box 4 and place or remove it from the slope fish transport vehicle 1. The gantry structure 32 is also provided with a slope fish transport vehicle inclined pull winch mechanism 33, which is used to drive the slope fish transport vehicle 1 to move on the track 22.
[0018] For the case of transporting fish from downstream to upstream, as shown in the figure, a lifting device 3 is set up upstream of slope 21, and a second lifting device is set up downstream of slope 21; for the case of releasing fish from upstream of slope 21 to downstream of slope 21, a lifting device 3 is set up only upstream of slope 21.
[0019] Further details are attached. Figure 2 As shown, the slope fish transport vehicle 1 includes a vehicle body 11, which is preferably a steel plate vehicle structure. The bottom of the vehicle body 11 is provided with a motion mechanism 12 that cooperates with the track 22. The motion mechanism 12 can be a slider structure that cooperates with the track 22, or a chassis + pulley structure that cooperates with the track 22. The top of the vehicle body 11 is fixedly connected to a horizontal support structure 13, which is a steel frame structure. The top surface of the steel frame structure forms a horizontal support surface, and a enclosure that cooperates with the fish box 4 is formed around the horizontal support surface. Preferably, a matching positioning block and positioning groove structure is provided between the fish box 4 and the top surface of the steel frame structure.
[0020] Further details are attached. Figure 3As shown, the gantry structure 32 includes a top gantry support plate 321 and several gantry columns 322 for supporting the gantry support plate 321. Preferably, there are four gantry columns 322, arranged in pairs on both sides of the fish box lifting and transfer mechanism 31 to avoid interfering with the fish box lifting and transfer mechanism 31. The fish box lifting and transfer mechanism 31 includes a slide rail 313 fixed to the bottom of the gantry support plate 321. Preferably, the slide rail 313 consists of two I-beams fixed to the bottom of the gantry support plate 321. The slide rail 313 is slidably fitted with a transfer mechanism 312. The transfer mechanism 312 includes a support plate. The top of the support plate is provided with a structure that slidably fits with the slide rail 313. This structure can be a pulley or a slider structure, driven by an external device such as a chain, push rod, or winch. Alternatively, it can be a trolley with independent power, with its wheels extending into the bottom plate of the I-beams on both sides. The bottom of the transfer mechanism 312 is provided with a fish box lifting mechanism 311.
[0021] Further details are attached. Figure 4 As shown, the fish box lifting mechanism 311 includes a fish box gripping device 3112, which includes a support plate. The bottom of the support plate is provided with a gripper, hook, or other connecting structure that cooperates with the fish box 4. The fish box gripping device 3112 is connected to the bottom of the transfer mechanism 312 through a scissor lifting mechanism. It also includes a lifting winch mechanism 3111 fixed to the bottom of the transfer mechanism 312. The lifting winch mechanism 3111 drives a steel wire rope that suspends the fish box gripping device 3112. The top of the support plate of the fish box gripping device 3112 is provided with a movable pulley that cooperates with the steel wire rope.
[0022] Furthermore, the gantry structure 32 extends a cantilever structure toward the slope 21, and a reinforcing rib is fixedly connected between the cantilever structure and the nearby gantry column 322. The slide rail 313 extends to the cantilever structure, and the projection of the cantilever structure in the vertical direction covers the slope fish transport vehicle 1 located at the extreme position of the track 22. That is, when the slope fish transport vehicle 1 is located at the upper / lower extreme position of the track 22, the stroke of the fish box lifting mechanism 311 can cover this position. The internal dimensions of the gantry structure 32 are sufficient for the fish box lifting and transfer mechanism 311 to place the fish box 4 on the flat fish transport vehicle 5, and the flat fish transport vehicle 5 does not interfere with the gantry column 322 when it travels within the gantry span.
[0023] Furthermore, the top of the gantry support plate 321 is fixedly connected to the inclined winch mechanism 33. A reversing pulley device 331 is provided on the top of the gantry support plate 321 behind the inclined winch mechanism 33. A wire hole is provided on the gantry support plate 321 behind the reversing pulley device 331. Below the wire hole, near the top of the slope 21, that is, near the corner of the top of the slope 21, a guide pulley device 332 is provided. The rear end of the body 11 of the slope fish transport vehicle 1 is fixedly connected to the lifting lug structure 111. A winch wire rope is driven to the drum 333 of the inclined winch mechanism 33. 334, the hoisting wire rope 334 is sequentially connected to the reversing pulley device 331, passes through the cable hole, and is connected and fixed to the lifting lug structure 111 with the guide pulley device 332. The wire rope 334 wound out of the drum 333 first changes from the horizontal direction to the vertical direction along the height of the gantry 32 by the reversing pulley device 331, and then reaches the guide pulley device 332 fixed at the top of the slope. After the wire rope 334 is wound through the guide pulley device 332, it is connected to the lifting lug structure 111 set at the upper end of the slope fish transport vehicle 1 to adapt to the angle of the slope fish transport vehicle 1 running along the slope track 2.
[0024] Furthermore, for the case of transporting fish from downstream to upstream, a second lifting device is provided at the downstream end of the slope 21. The second lifting device includes a gantry structure 32 and a fish box lifting and transfer mechanism 31 that is slidably mounted on the gantry structure 32, but no inclined winch mechanism 33 is provided.
[0025] The integrated cable-stayed and lifting fish box transfer system functions to transport fish boxes 4 on steep slopes. In multi-stage dam crossings, it can simultaneously fulfill the functions of transporting and releasing fish. The transfer method of the integrated cable-stayed and lifting fish box transfer system is illustrated using the example of transporting fish boxes 4 from the bottom to the top of the slope.
[0026] The transfer method for the integrated inclined pull and lifting fish box transfer equipment described above includes the following steps: S1. After the fish box 4 collects the target fish from the fish collection stage, it is transported by the flat transfer vehicle 5 to the designated position within the span of the second lifting equipment, waiting for the fish box lifting and transfer mechanism 31 to grab the fish box 4. S2. After the fish box lifting mechanism 311 picks up the fish box 4, it lifts it to a specified height. After the fish box reaches the specified height, the fish box transfer mechanism 312 moves forward along the slide rail 313, driving the fish box lifting mechanism 311 and the fish box 4 forward to a specified position. Directly below the specified position is the stopped slope fish transport vehicle 1. The fish box lifting mechanism 311 lowers and places the fish box 4 on the horizontal support structure 13 of the slope fish transport vehicle 1. After the fish box 4 is placed, the inclined winch mechanism 33 on the lifting equipment 3 at the top of the slope is activated, and the fish transport vehicle 1 on the slope is pulled up along the track 22 by the winch wire rope 334. After reaching the designated position, the fish box lifting and transfer mechanism 31 of the lifting equipment 3, which is directly above the fish box 4, lifts the fish box 4 to the designated height. After the fish box 4 reaches the designated height, the fish box transfer mechanism 312 transfers the fish box 4 to the designated position and puts it down, completing the slope transfer work of the fish box 4.
[0027] During the fish release process, the fish box 4 needs to be placed on the slope fish transport vehicle 1 and fixed. Then, the fish box 4 is transported down the slope 21 to the water surface. The fish release hole of the fish box opens the cover under the action of water pressure, thus realizing the fish release process.
[0028] This application proposes an integrated cable-stayed and lifting fish box transfer system at a water conservancy hub. This integrated system can overcome the challenges of transporting fish boxes on steep inclines and also enables long-distance, multi-tiered fish box transport. In the case of multi-tiered dam crossings, it can facilitate both fish transport and release.
[0029] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be considered within the scope of protection of the present invention.
