[0002] Currently, in fish protection measures of hydropower stations, fish passage facilities are generally built to achieve fish over-dam, and fish transportation is generally required in fish passage facilities. There are many ways of fish transportation, such as fish elevators, fish transport trucks, navigation unmanned fish transport vehicles, rail fish transport vehicles, etc. Whether transporting fish upward or downward, the elevation difference between fish transportation locations needs to be overcome. Generally, the terrain near the dam site of a water conservancy project is relatively complex, and even has a relatively large slope. Whether it is a fish transport truck and an unmanned fish transport vehicle running on a road surface or a rail fish transport vehicle, the slope that these vehicles can overcome is limited, and roads need to be built or tracks need to be laid on complex terrain.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Such as Figures 1 to 9As shown in the figure, a suspended fish transport vehicle includes a running trolley 1, a horizontal holding mechanism 2, a suspension bracket 3, a lifting mechanism 4, a guiding mechanism 5, an automatic lifting beam 6, a fish tank 7, a transfer flatbed 8, a track device 9 and a control unit 10. The fish tank 7 is placed on the transfer flatbed 8. The fish tank 7 is inserted and connected to the automatic lifting beam 6. The automatic lifting beam 6 is hoisted and connected to the lifting mechanism 4 through the guiding mechanism 5. Both the lifting mechanism 4 and the guiding mechanism 5 are fixed on the suspension bracket 3. The suspension bracket 3 is hinged to the horizontal holding mechanism 2 and the suspension bracket 3 is also hinged to the running trolley 1. The horizontal holding mechanism 2 is fixed on the running trolley 1. The running trolley 1 is slidably connected to the track device 9. The track device 9 is suspended. The running trolley 1, the horizontal holding mechanism 2, the suspension bracket 3, the guiding mechanism 5, the automatic lifting beam 6 and the transfer flatbed 8 are all electrically connected to the control unit 10.

[0027] As Figures 1 to 2 shown, the elevation position of one end of the track device 9 is greater than or less than the elevation position of the other end of the track device 9. Elevation refers to the distance from a certain point along the plumb line direction to the absolute reference plane. In this embodiment, one end of the track device 9 is arranged at a low elevation position and the other end is arranged at a higher elevation position. The track device 9 includes a horizontal track and an inclined track. Both the horizontal track and the inclined track are composed of multiple sections. The inclination angle of the track can be set according to the terrain conditions. The horizontal track and the inclined track are fixedly connected. Both the horizontal track and the inclined track include a steel rail 91 and a bent frame 93. The bent frames 93 are arranged at uniform intervals along the track line. The bent frame 93 is made of steel structure or reinforced concrete structure, and the bent frame 93 is a portal bent frame. A cross beam 931 is fixedly arranged at the top of the portal bent frame. The steel rail 91 is suspended below the cross beam 931, and the axis of the steel rail 91 is perpendicular to the axis of the cross beam 931. The entire suspended fish transport vehicle runs inside the portal bent frame. The steel rail 91 is two parallel and juxtaposed steel rails. The cross section of each steel rail 91 is an I-shaped cross section. A rack 92 is fixedly arranged at the bottom of each steel rail 91. The rack 92 is arranged along the entire length of the bottom of the I-shaped steel rail 91.

[0028] As Figure 3 shown, corresponding to the two I-shaped steel rails 91, two running trolleys 1 are provided, that is, each steel rail 91 is slidably connected with a running trolley 1. The running trolley 1 includes a vehicle frame 11, a supporting wheel 13 and a gear driving mechanism 12. The side structure of the vehicle frame 11 is a T-shaped structure. The front and rear ends fixedly support the wheels 13. The lower part is hinged to the suspension bracket 3. The vehicle frames 11 of each running trolley 1 are respectively arranged on both sides of the I-shaped steel rail 91. The supporting wheels 13 are located on both sides of the steel rail 91 and are fixed on the vehicle frame 11. The wheel rims of the supporting wheels 13 support inside the I-shaped steel rail 91. The supporting wheels 13 can run along the length direction of the steel rail 91 to transfer the weight of the entire suspended fish transport vehicle to the I-shaped steel rail.

[0029] The gear drive mechanism 12 is arranged below the vehicle frame 11. The gear drive mechanism 12 is fixedly connected to the vehicle frame 11. The gear drive mechanism 12 includes a drive motor, a rotating shaft, and a gear 121. The gear 121 meshes with a rack 92 below the I-shaped steel rail 91 to provide upward running power for the running trolley 1 or braking force during the downhill process. The gear 121 is fixed on the rotating shaft, and the rotating shaft is fixedly connected to the output shaft of the drive motor. The drive motor is electrically connected to the control unit 10. A hinge bracket 31 is further arranged at the bottom of the vehicle frame 11. The vehicle frame 11 is hinged to the suspension bracket 3 through the hinge bracket 31, and the hinge bracket 31 is fixedly connected to the suspension bracket 3.

[0030] As Figures 3 to 4 shown, the function of the horizontal holding mechanism 2 is to keep the structures below the suspension bracket 3 and the fish tank 7 running in a horizontal state. The horizontal holding mechanism 2 includes a worm drive motor 24, a worm 22, a turbine 21, and a connecting rod 23. One end of the connecting rod 23 is hinged to the suspension bracket 3, and the other end of the connecting rod 23 is hinged to the turbine 21. The turbine 21 is meshed and connected with the worm 22. The worm 22 is fixedly connected to the output shaft of the worm drive motor 24. The worm drive motor 24 is electrically connected to the control unit 10. The worm drive motor 24, the worm 22, and the turbine 21 are all fixed on the vehicle frame 11.

[0031] The suspension bracket 3 is a planar quadrilateral steel structure. A horizontal sensor 33 is arranged on the suspension bracket 3. The horizontal sensor 33 is electrically connected to the control unit 10. The horizontal sensor 33 is arranged on the top surface of the suspension bracket 3 to detect the inclination angle of the suspension bracket 3. The control unit 10 is fixed on the suspension bracket 3, and the control unit 10 is any one of a single-chip microcomputer, a PLC, or an industrial control computer.

[0032] Two hinge brackets 31 protrude from the upper surface of the suspension bracket 3. The top of the hinge bracket 31 is hinged to the bottom of the vehicle frame 11 of the running trolley 1. In this way, while the weight of the fish tank 7 can be transmitted to the running trolley 1, the suspension bracket 3 can rotate around the hinge point to ensure the horizontal state of the fish tank 7 during slope running.

[0033] As Figure 9As shown in the figure, when the running trolley 1 runs on a non-horizontal track, the entire suspended fish transporter will tilt. When the horizontal sensor 33 detects a non-horizontal state, the control unit 10 controls the worm drive motor 24 to drive the worm 22 to rotate, and then drives the worm gear 21 to rotate. The worm gear 21 drives the suspension bracket 3 to rotate through the connecting rod 23 to adjust the angle between the suspension bracket 3 and the running trolley 1, so that the suspension bracket 3 remains in a horizontal state. Both ends of the worm 22 are fixed on the frame 11 of the running trolley 1 and can rotate driven by the worm drive motor 24. The center of the worm gear 21 is also hinged on the frame 11 and meshes with the worm 22 to rotate. There is a hinge point for the connecting rod 23 on the worm gear 21. One end of the connecting rod 23 is hinged on the worm gear 21, and the other end is hinged on the end of the suspension bracket 3.

[0034] As Figures 5 to 7 shown, the lifting mechanism 4 includes a first drum 41, a drum drive reduction motor 42, a first movable pulley 43, a balance pulley 44, a steel wire rope 45, a second movable pulley 46 and a second drum 47. The top of the automatic lifting beam 6 is provided with a lifting lug 61. The first movable pulley 43 and the second movable pulley 46 are respectively hinged to the top of the automatic lifting beam 6 through the lifting lug 61. One end of the steel wire rope 45 is fixed to the first drum 41, and the other end of the steel wire rope 45 passes through the first movable pulley 43, the balance pulley 44 and the second movable pulley 46 in sequence and is fixed to the second drum 47. Both the first drum 41 and the second drum 47 are driven by the drum drive reduction motor 42. The drum drive reduction motor 42 has a double-axis output, and the drum drive reduction motor 42 is electrically connected to the control unit 10. The drum drive reduction motor 42, the first drum 41, the second drum 47 and the balance pulley 44 are all fixed to the bottom of the suspension bracket 3. The number of balance pulleys 44 is one or two. When there is one balance pulley 44, the steel wire rope passes through the first movable pulley 43, the balance pulley 44 and the second movable pulley 46 in sequence and is fixed to the second drum 47. When there are two balance pulleys 44, the steel wire rope passes through the first movable pulley 43, the two balance pulleys 44 and the second movable pulley 46 in sequence and is fixed to the second drum 47, as Figure 6 shown. The drum drive reduction motor 42 includes a motor and a reducer. The motor drives the first drum 41 and the second drum 47 respectively through the reducer.

[0035] The guiding mechanism 5 includes an upper guiding tube 51 and a lower guiding tube 52. The upper guiding tube 51 is uniformly fixed to the bottom of the suspension bracket 3. The lower guiding tube 52 is fixed to the top of the automatic lifting beam 6 and corresponds to the position of the upper guiding tube 51. The diameter of the upper guiding tube 51 is larger than that of the lower guiding tube 52. The lower guiding tube 52 is sleeved in the upper guiding tube 51 and is slidably connected to the upper guiding tube 51, so as to prevent the automatic lifting beam from tilting due to rotation around the lifting lug 61 during the lifting and lowering process of the automatic lifting beam 6.

[0036] A cable reel 32 is also provided at the bottom of the suspension bracket 3. The cable reel 32 is electrically connected to the control unit 10. A cable is wound around the cable reel 32. A shaft-passing mechanism 62 is provided at the bottom of the automatic lifting beam 6. The shaft-passing mechanism 62 is electrically connected to the control unit 10 through the cable. The shaft-passing mechanism 62 is an electric push rod.

[0037] The drum drive reduction motor 42 drives the first drum 41 and the second drum 47 to wind the wire rope 45, thereby lifting or lowering the automatic lifting beam 6. The automatic lifting beam 6 is a planar frame structure. There are two lifting lugs 61 in the middle of the top surface. The top lifting lugs 61 are hinged to two movable pulleys. The four corners of the top surface are respectively fixed to the bottom of the lower guide pipes 52 of the guiding mechanism 5. The four corners of the bottom surface are automatic shaft-passing mechanisms 62. The operation of the automatic shaft-passing mechanism 62 is powered and controlled by a cable hanging from the cable reel 32 fixed to the bottom of the suspension bracket 3 on the suspension bracket 3.

[0038] As Figures 7 to 8 shown, the fish box 7 is a fish transportation container. A lifting lug hole 71 is provided at the top of the fish box 7. Specifically, four lifting lug holes 71 are provided at the four corners of the top of the fish box 7. The lower aperture of the lifting lug hole 71 is larger than the shaft diameter of the shaft-passing mechanism 62, and the upper aperture of the lifting lug hole 71 is equal to the shaft diameter of the shaft-passing mechanism 62. The four lifting lug holes 71 adopt a structure with a larger lower part and a smaller upper part. The diameter of the larger lower hole is larger than the shaft diameter of the shaft-passing mechanism 62 of the automatic lifting beam 6. When the automatic lifting beam 6 falls onto the fish box 7, the axis of the shaft-passing mechanism 62 coincides with the axis of the larger lower part of the lifting lug hole 71. Such a matching structure can adapt to the position error between the automatic lifting beam 6 and the fish box 7.

[0039] A guiding track 72 is provided at the bottom of the fish box 7. A guiding wheel 81 is provided on the transfer flat car 8. The guiding track 72 is slidably connected with the guiding wheel 81 in a matching manner. The cooperation between the guiding wheel 81 and the guiding track 72 on the fish box 7 can fix the relative position between the fish box 7 and the transfer flat car 8, facilitating the grasping of the fish box 7 by the automatic lifting beam 6.

[0040] The transfer flat car 8 can be an electric flat car running on a track. The transfer flat car 8 further includes a ground track 82. The ground track 82 is arranged directly below the suspended fish transportation vehicle track device 9. The laying direction of the ground track 82 can be parallel or perpendicular to the direction of the suspended fish transportation vehicle track device 9. A position sensor 83 is arranged at the parking position of the transfer flat car 8. The position sensor 83 and the transfer flat car 8 are both wirelessly connected to the control unit 10. A position sensor 83 is arranged at the parking position of the transfer flat car 8. When the transfer flat car 8 reaches the preset position and the position sensor 83 senses the position of the fish box 7, the control unit 10 sends a signal and the transfer flat car 8 stops.

[0041] The control unit 10 is the control center for the various actions of the suspended fish transporter. It is installed on the suspension frame 3 and can control the actions of the running trolley 1, the horizontal holding mechanism 2, the lifting mechanism 4, and the automatic hanging beam 6, obtain the signals of various sensors, and provide signal interfaces for remote control and remote operation.

[0042] The specific working process of the suspended fish transporter is as follows: The function of the suspended fish transporter is to transport the fish box 7 back and forth at different elevations. Taking the transportation of the fish box from a lower elevation to a higher position as an example, the operation process of the suspended fish transporter is described.

[0043] After the fish box 7 collects the target fish in the fish collection link, it is placed on the transfer flatbed 8. Under the guiding action of the guiding wheels 81 on the transfer flatbed 8, the guiding track 72 of the fish box 7 is relatively positioned with the guiding wheels 81 on the transfer flatbed 8, thereby determining the position of the fish box 7 on the transfer flatbed 8, facilitating the subsequent hoisting of the fish box 7. The transfer flatbed 8 travels along its ground track 82 towards the suspended fish transporter. When the position sensor 83 fixed on the ground senses the fish box 7, the transfer flatbed 8 stops and waits for the suspended fish transporter to hoist the fish box 7.

[0044] The lifting mechanism 5 of the suspended fish transporter operates to lower the automatic hanging beam 6. Under the guiding action of the guiding mechanism 5, the automatic hanging beam 6 descends vertically while maintaining a horizontal state. When the automatic hanging beam 6 reaches the fish box 7, the lifting mechanism 4 stops operating. At this time, the shaft-passing mechanism 62 of the automatic hanging beam 6 aligns with the large-diameter hole of the lifting lug hole 71 of the fish box 7, and then the shaft-passing mechanism 62 operates. The lifting shaft of the shaft-passing mechanism 62 penetrates into the large hole of the lifting lug hole 71 of the fish box 7, and the lifting mechanism 4 operates the automatic hanging beam 6 to hoist the fish box 7 upward and leave the transfer flatbed 8.

[0045] The gear drive mechanism 12 of the running trolley 1 drives the gear 121 to mesh with the rack 92 on the track device 9 to drive the entire suspended fish transporter forward. When the supporting wheel 13 of the running trolley 1 runs to the inclined plane of the track device 9, after the horizontal sensor 33 installed on the suspension frame 3 detects the inclination angle of the suspension frame 3, the control unit 10 controls the horizontal holding mechanism 2 to operate. The worm drive motor 24 drives the worm 22 to rotate, and the worm gear 21 drives the connecting rod 23 to adjust the angle between the suspension frame 3 and the running trolley 1, ensuring that the suspension frame 3 carrying the fish box 7 is in a horizontal position, as Figure 9 shown. The horizontal holding mechanism 2 can operate in real time according to the data of the horizontal sensor 33.

[0046] The running trolley 1 continuously drives the suspended fish transporter forward to a predetermined target position. Another transfer flatbed 8 has been parked directly below the predetermined position. The lifting mechanism 4 lowers the automatic hanging beam 6 and the fish box 7 onto the transfer flatbed 8, the shaft-passing mechanism 62 withdraws the lifting shaft, and then the automatic hanging beam 6 is lifted away from the fish box 7 to complete the transfer of the fish box 7.

[0047] The suspended fish transporter can realize two-way transportation of fish boxes and can also realize the hoisting operation of empty boxes.

It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
