Description

[OI] The present invention belongs to the technical field of long-distance fish conveying system structures of fish lift engineering and methods.
BACKGROUND ART
[02] In existing dam design, consideration must be made to construction of a fish passing channel system, for example, fish lift engineering. The fish lift engineering, as a type of large-sized engineering, is built between the downstream and upstream of a dam, and requires a high cost. Dam construction has certain influence on local ecology, especially, it has great influence on biological habits such as spawning and migration of various fish in upstream and downstream mainstreams and branches. In order not to break local ecological chain balance, fish conveying, lifting and releasing systems/devices should assist the fish lift engineering in perfecting the ecological functions. A common system is not perfect, is not friendly to fish in upstream and downstream of the dam, and is prone to cause unnecessary damage or death of the fish. Furthermore, when the fish is conveyed for a long distance, it is difficult not to cause injury or death to the fish in the conveying process.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[52] As shown in FIGs. 1, 2 and 3:
[53] Implementation
[54] An initial planned releasing place of a fish lift for fish passing is initially set at a river confluence and other large branch confluences. As a drop-off point is far away from a dam site, fish collecting and conveying systems should be combined for releasing. After crossing a dam, a fish-conveying box is placed on a fish-conveying ship and conveyed by the fish conveying ship to an upstream releasing point for releasing.
[55] After vertical conveying, the fish-conveying box is located at a dam section 1# and may be directly transferred to cross the dam, a fish-collecting ship abuts against a reservoir area of the dam section 1# to receive the fish-conveying box, however, the dam section 1# is close to a water diversion opening of a power station and has a certain flow speed, safety of the fish conveying ship and the dam may be influenced, such that an alternative solution is considered, that is, the fish-conveying box on the dam is horizontally conveyed from the dam section 1# to a dam section 2# on a right bank, and the fish-conveying box is placed. In the alternative solution, the dam section 2# is far away from the water diversion opening of the power station, a water surface is calm, but transfer on the dam is difficult to some extent, and the two solutions are compared for selection in the report.
[56] Dam crest design
[57] A vertical shaft in the dam is 3.0 m~3.0 m and extends to a dam crest, and the vertical shaft is arranged on a downstream side of a dam-crest gantry crane rail and a monitoring ditch. When the fish lift does not operate, a cover plate is used to cover an opening of the vertical shaft, and the dam crest passing safety 1s guaranteed.
[58] (1) putting solution for dam section 1#
[59] A maximum trash rack crossing flow velocity at a trash rack at a power intake of a hydropower station is about 0.92 m/s, a flowing area of water flow of a reservoir in front of the water inlet is rapidly enlarged and a flow velocity is rapidly reduced, by means of calculation, a flow velocity near the dam section 1# is smaller than 0.1 m/s, compared with a Yangtze River waterway which is known as a “golden waterway”, water flow of a reach from Yichang to Wuhan generally has a flow velocity of 1.0 m/s-1.7 m/s in a dry period and a flow velocity of 2.0 m/s-3.0 m/s in a flood period, and water flow of a reach below
Wuhan has a general flow velocity of 0.8 m/s-1.2 m/s in the dry period and a general flow velocity of 1.6 m/s-1.9 m/s in the flood period, such that it may be seen that basically the flow velocity at the water inlet does not influence operation of a ship in front of the dam.
[60] (2) putting solution for dam section 2#
[61] When transferred to the dam section 2# at the right bank, the fish lift should cross a middle overflow dam section, a dam-crest working bridge may not be widened due to an operation influence of a crest-outlet service gate, and a dam-crest fish conveying vehicle may only pass below a dam-crest gantry crane, such that large interference is caused to operation of the gantry crane, and the fish-conveying box is recommended not to be put in a dam section 5#.
[62] Comparing a dam section 2# fish-releasing solution with the dam section 1# fish-releasing solution, fish trapping systems have completely identical structural apparatuses; the difference is that the fish-conveying box does not directly move horizontally after being lifted to the crest of the dam section 1# by an upstream trolley and is lowered to a transfer ship, berthed in a reservoir in front of the dam section 1#, of the fish-releasing system, but moves horizontally and is lowered to a dam-crest fish conveying vehicle parked at the crest of the dam section 1#, then conveyed to the dam section 2# along the dam crest by the dam-crest fish conveying vehicle, and finally lowered, by means of horizontal moving of the dam-section-2# trolley, to the transfer ship, berthed in a reservoir in front of the dam section 2#, of the fish-releasing system. According to the dam section 2# fish-releasing solution, one fish conveying vehicle and one trolley are required to be additionally arranged for the metal structure apparatus of the conveying and dam crossing system.
[63] Summary
[64] According to the solution, one fish conveying vehicle is additionally arranged for a metal structure apparatus at a dam crest and is configured to convey a fish-conveying box between a dam section 1# and a dam section 2#; one trolley is additionally arranged at a crest of the dam section 2# and is configured to horizontally move, along the dam crest, the fish-conveying box parked on the dam-crest fish conveying vehicle at the dam section 2# to a position above a transfer ship, berthed in a reservoir in front of the dam section 2#, of a fish-releasing system and lower the fish-conveying box to discharging fish in the fish-conveying box into the transfer ship of the fish-releasing system so as to transfer the fish to the fish-releasing system from a conveying and dam crossing system.
[65] Dam-crest fish conveying vehicle
[66] The fish conveying vehicle is an automated guided vehicle with a rated load capacity of 10 tons. The automated guided vehicle (AGV) is a vehicle equipped with an automatic guide device, for example, an electromagnetic or optical device, may travel along a preset guide path,
[67] The fish conveying vehicle has safety protection and various transfer functions, and takes a rechargeable storage battery as a power supply. A conveying starting point of the fish conveying vehicle is the crest of the dam section 1#, an end point is the crest of the dam section 2#, a conveying distance is 180m, and a running speed is 60m/min.

[70] Operation flowchart
[71] The operation flow of a dam crest and releasing system metal structure apparatus is as follows:
[72] (1) a movable top cover of a fish-conveying box is closed after fish in a transfer chamber are completely discharged into the fish-conveying box;
[73] (2) a fish-conveying vehicle conveys the fish-conveying box to a bottom of a vertical shaft of a dam section 1# along a guide rail by means of a low-line highway under the dam;

[76] (5) the dam-crest fish conveying vehicle conveys the fish-conveying box from the crest of the dam section 1# to a position below the trolley at a crest of the dam section 5# along the guide rail;
[77] (6) the dam-section-2# trolley hoists the fish-conveying box to move to a position above a transfer ship, berthed in a dam-front reservoir of the dam section 2#, of a fish-releasing system along a horizontal rail on a dam-crest bent frame;
[78] (7) the dam-section-2# trolley lowers the fish-conveying box on the transfer ship of the fish-releasing system, a fish-discharging hole in a side of the fish-conveying box is opened, and the fish in the fish-conveying box are discharged into the transfer ship of the fish-releasing system,
[79] such that the fish is transferred to the fish-releasing system from the conveying and dam crossing system;
[80] (8) the fish-discharging hole in the side of the fish-conveying box is closed, and the fish-conveying box is lifted from the dam-section-2# trolley to the dam crest;
[81] (9) the dam-section-2# trolley hoists the fish-conveying box to move to a position above the dam-crest fish conveying vehicle along the horizontal rail on the dam-crest bent frame;
[82] (10) the dam-section-5# trolley lowers the fish-conveying box on the dam-crest fish conveying vehicle and is unhooked from the fish-conveying box;
[83] (11) the dam-crest fish conveying vehicle conveys the fish-conveying box from the crest of the dam section 2# to a position below the upstream trolley at a crest of the dam section 1# along the guide rail;
[84] (12) the upstream trolley hoists the fish-conveying box to move to the top of the vertical shaft along the horizontal rail on the dam-crest bent frame;
[85] (13) the upstream trolley lowers the fish-conveying box along the fish-conveying box guide rail and on the fish conveying vehicle parked at the bottom of the vertical shaft and is unhooked from the fish-conveying box;
[86] (14) the fish conveying vehicle conveys the fish-conveying box to the transfer chamber along the guide rail by means of the low-line highway under the dam; and
[87] (15) the movable top cover of the fish-conveying box is opened. The fish conveying and dam crossing system enters a next cycle.
[88] Thus, the operation flowchart of the metal structure apparatus for transferring the fish to the fish-releasing system by the conveying and dam crossing system is completed.

De ww 5 [92] Solution comparison and selection
[93] For dam section 1# fish-releasing and the dam section 2# fish-releasing, the metal structure apparatuses of the two solutions are feasible. Compared with the dam section 2# fish-releasing, the dam section 1# fish-releasing has a shorter dam crossing time and less apparatus investment. Therefore, a dam section 1# fish-releasing solution is a recommended solution for the conveying and dam crossing system in the engineering.
[94] Investment
[95] A main difference between the dam section 1# fish-releasing solution and the dam section 2# fish-releasing solution is that the dam section 1# fish-releasing solution should add a trolley required by a conveying section on a dam and add a dam-crest fish conveying vehicle, and according to measurement and calculation, the dam section 2# solution should increase the investment by about 2,180,500 Yuan compared with the dam section 1# solution. [9%] Comparison and selection result
[97] Advantages and disadvantages for putting the dam section 1# solution and the dam section 2# solution are summarized and compared, as specifically shown in Table 2. A comparison result shows that both the two solutions may achieve transfer dam-crossing putting of the fish-conveying box, however, the dam section 1# solution is simpler, more efficient and shorter in transfer time, improves a transfer survival rate of fish, is smaller in investment and has no potential safety hazard, the dam section 1# is recommended to serve as a placement point of the fish-conveying box at the present stage.
[98] The fish-conveying box has a full-loaded dead weight of 10 tons, and is hoisted by an upstream 2x63KN trolley, and the fish-conveying box has double hoisting points and may be prevented from rotating in a hoisting process.
