Description

A vehicle-mounted fish transport box system suitable for maintaining fish ecological behavior

technical field

The invention relates to the field of aquatic biology research, in particular to a vehicle-mounted fish tank system suitable for maintaining the ecological behavior of fish.

Background technique

In order to protect fish resources and alleviate the serious impact of dams or hydropower facilities on river ecosystems, corresponding fish protection measures are required during the construction of dams and hydropower projects, such as building fishways, fish ladders, container transportation, etc. Fish protection measures such as fishing boats. During the migration process of fish, the heights of the dams encountered are different, and the fish passing facilities are also different. Generally, low-head dams can be realized through fishways and fish ladders, but high-head dams can be realized with the help of fishways and fish ladders. At the same time as the ladder, it is necessary to cooperate with the fish transport vehicle. Fish trucks transport fish to suitable habitats. In addition to the function of slowing down the stress response of fish to adapt to long-distance transportation, this kind of fish transport vehicle should also minimize the disturbance to the ecological behavior of fish.

The role of fish transport vehicles as a fish protection measure in high head dams is critical. When transporting fish, it is necessary to ensure that the surface of the transported fish is not injured, and that the physiological characteristics of the fish are not abnormal, such as the fish jumping in the water, the swimming behavior of the fish is not normal, the spawning rate of the parent fish is frightened, etc. It is also necessary to maintain the behavioral characteristics of the fish so that the fish can quickly adapt to the river environment and find a habitat after being released from the fish transport vehicle into the river. For the important tasks undertaken by the fish transport vehicle, the existing fish transport vehicle and the method for transporting fish still need to be improved. Ordinary fish transport vehicles mainly transport commercial fish, and the protection of fish is mainly reflected in oxygen supply and lowering water temperature, but does not involve the method of maintaining fish behavior characteristics. Among them, the method of lowering the water temperature is contrary to the need to maintain fish behavior, because it is difficult for fish to return to normal swimming, foraging and harm avoidance behaviors in a short period of time after being transported at low temperature. In order to ensure that fish maintain ecological behavior during transportation, it is necessary to invent a vehicle-mounted fish transport box system that has high safety performance, can maintain fish ecological behavior, and is easy to operate.

Detailed ways

As shown in Figures 1-3, a vehicle-mounted fish transport box system suitable for maintaining fish ecological behavior,

It includes the truck-mounted lifting device installed on the transport vehicle, which is matched with the fish box, and the truck-mounted lifting device can

Transport the fish tank far from the shore to the vicinity of the fish tank, and also load and unload the closed tank on the truck;

In the fish transport box, the box wall of the closed box is fixed by the anti-collision layer (to prevent the fish from being injured by the wall) and the

layer (plays the role of fixing the sponge body or foam board, and also plays the role of preventing water leakage), thermal insulation layer (makes the water temperature change slowly, and can prevent the large temperature difference in the water for transporting fish during long-distance transportation. It can also prevent the water temperature from changing due to the influence of the external environment) and a protective layer (which can prevent damage to the insulation material). The top of the closed box is provided with a fish opening 8 and an observation opening 17. The fish opening 8 is a rectangular opening. The fish and water collected by the ladder or the fishing boat are discharged into the casing through the fish port 8, and the observation port 17 is a circular mouth; the fish port 8 is provided with a transparent cylinder cover, and the observation port 17 is provided with a transparent skylight for Observe the water level in the casing. Nets are set above the viewing port 17, which can prevent the fish from overflowing when the casing water accidentally overflows. The fish-out box 19 that is arranged on the fishway 12 matching at the transport vehicle rear end,

The fish passage 12 is a telescopic tank with a semicircular cross section, which can be directly stretched to the target fish habitat, and can reduce the use of oxygenated plastic bags and reduce the labor of the discharge staff during the fish proliferation and discharge. workload, and the fish are not separated from the water during the flow into the habitat;

The top of the closed box is also provided with an exhaust port 5, which is provided with a plug made of stone with gaps, which can ensure frequent air exchange in the box, and can also prevent the air from falling when the road is rough during transportation. A large amount of water in the tank overflows, the fish outlet tank 19 is provided with a first valve 10 and a second valve 11, and the first valve 10 is provided with a hand valve 16;

Because there are differences in the water temperature in the fish transport box and the purpose habitat, so in order not to allow the fish to be injured because of a sudden temperature change, a circulating water pump 2 is arranged outside the fish transport box, and the fish can be pumped into the box while putting the fish. The circulating water pump 2 can simultaneously create a circulating water flow in the casing to keep the water flow in a flowing state. Water flow is very important for fish to maintain ecological behavior. It can reduce the stress response, reduce the time for fish to adapt to the new environment after release, and improve the survival rate.

An oxygen supply machine 14 connected to the generator 1 and a circulating water pump 2 are arranged outside the fish tank. One end of the oxygen supply pipe 13 communicates with the oxygen outlet of the oxygen supply machine 14, and the other end of the oxygen supply pipe 13 is inserted from the top of the closed box. The closed box is connected with the oxygen outlet pipe 15 laid on the bottom of the closed box, and the fish can slowly adapt to the habitat environment through the circulation of the habitat water;

The circulating water pump 2 is communicated with the water inlet pipe 4 and the outer water inlet pipe in the case respectively, and the inner water inlet pipe 3 is communicated with the circulating water pump 2, and the enclosed casing of the water inlet pipe 4 in the case is longitudinally equipped with a fish net 6.

The main function of water inlet pipe 4 in the case is to recirculate the water in the water tank when injecting new water in the case, so that the water temperature in the case remains uniform, so that fish will be prevented from overreacting because of temperature unevenness. Both the fresh water injected into the tank and the circulating water enter through the water inlet shown in Figure 1-3. The shock absorption and anti-collision of the fish transport vehicle mainly occur during the process of transporting fish and unloading fish (in the target habitat). In the process of transporting fish, the anti-collision layer in the box can play a role; while in the process of unloading fish, there may be dry water in the fish unloading tank, that is, there are only fish but no water. This can be done by circulating water pump 2 Just keep pouring water into the tank. During the whole process, measures such as water flow, temperature control, and anti-collision measures are used to maintain the maximum ecological behavior of fish.

The truck-mounted lifting device includes a swing arm frame 18 and a suspension hook installed at one end of the swing arm frame 18 .

The anti-collision layer of the box wall is a sponge layer or a foam layer to prevent fish from colliding with the hard wall of the box.

The fixed layer of the box wall is a seamless welded metal wall layer to prevent water leakage in the box.

The protective layer is a protective layer made of metal material.

When the fish box 19 was opened, fish just flowed into the habitat of the purpose by putting the fishway 12.

The cylinder head is installed on the fish port 8 by the cylinder head supporting column 7.

It is mainly used to assist in the transfer of fish, including broodstock, juveniles and sub-adult fish, among which broodstock is the main fish, but the spawning rate of the broodstock may drop or stop spawning after the broodstock is disturbed, so the protection of the broodstock is especially important.

When the fish transport vehicle is far away from the fish ladder and the fish collection ship, the fish transport box can be transported to the vicinity of the fish transport vehicle with the hoisting device on the truck, and then the fish and water release port of the fish collection box can be opened to release the fish and water into the transport tank. Inside the fish box. The fish transport box is usually fixed on the base of the truck compartment, so the bottom area of the fish transport box does not need to exceed the bottom area of the cargo compartment. The volume of the fish transport box and the specifications of the cargo compartment of the truck should be designed and selected according to the size of the fish box collected by the fish ladder or the fish collection boat. The fish and water are all poured into the fish transport box, and the volume of water and fish reaches 1/2-2/3 of the water tank, which can improve the efficiency of fish transport and prevent the water and fish in the tank from overflowing. When putting fish and water into the fish transport vehicle, the speed of putting fish and water should be adjusted according to the stress behavior of the fish. To observe the behavior of fish through the observation port 17, the field of view of the observation port 17 will cover every corner inside the water tank. It was observed that the overall fish behavior in the tank was stable, and the water and fish could be put in at the original speed. If most of the fish have excessive behavior, such as jumping out of the water and bumping against the wall, you can slow down the water release speed until the fish show a stable behavior. Slowing down the water release rate will not reduce the abnormal behavior of the fish, you can stop the water discharge, and then release the water and fish after the behavior is stable. When the density of fish injected into the fish box is too low, and there are multiple fish boxes, some water can be released in the fish box. When the fish density is appropriate, put the fish and fish in other boxes again water, which can improve the efficiency of fish transportation. When injecting water and fish from different water tanks into the fish tank, keep the circulating water pump running so that the water temperature in the tank of the fish tank can be kept uniform quickly. In the process of putting in water and fish, oxygenation needs to be carried out continuously, and the water discharge is stopped when the water level reaches 2/3 of the height of the box body, and the observation hole and the fish inlet hole are covered.

After transporting the fish to the destination, if the fish truck is unloading fish and water on the shore, extend the fish channel into the river, then introduce the suction pipe into the river to pump water into the water tank, and then open the fish outlet of the fish truck Case 19, can allow fish to adapt to the aquatic environment of destination slowly like this, can allow fish and water evenly enter in the river of destination again in unloading fish process.
