Above-mentioned deep sea becomes water layer temperature measurement water intaking system during operation: when the temperature of the seawater at the bottom of the ship does not meet the temperature of the cultured fishes, the central processing unit 4 opens the valves on the water intake pipe according to the measured temperatures at the bottom of the ship, the culture water tank and the lower end of the water intake pipe, and the suction pipe of the water pump 9 is in a state that the water intake pipe of the seabed valve box and the deep water intake pipe are connected in parallel; according to the established program of the central processing unit, the opening degrees of the valve I and the valve II are adjusted, and the temperature in the culture water tank is mixed with the bottom seawater and the deep seawater to meet the requirement of fish culture; when the opening degrees of the valve adjusting valve I and the valve II are adjusted to the specified values, the temperature of the aquaculture water tank still cannot meet the requirements, the central processing unit 4 sends an instruction to the hydraulic crane 2, and the angle and the depth of the water taking pipe 1 are adjusted until the temperature in the aquaculture water tank reaches the set values.
The deep sea cultivation ship adopts the deep sea water-layer-changing temperature-measuring water taking system.
Meanwhile, the sonar sensor 8 and the compensation device are arranged on the aquaculture worker ship, when the water intake pipe is located in sea water and the ship jolts under the action of waves, the sonar sensor 8 is used for preventing the water intake pipe from impacting an underwater submerged reef when the ship sails; the compensation device compensates the displacement generated between the ship and the water intake pipe, and eliminates the threat to ship stability.
The technical difficulty is as follows: the culture ship requires continuous circulation of a circulating water system in the ship anchoring process during the marine culture, and when the environment is not suitable for culture, the fishing ship can flexibly search for a suitable culture environment; when the environmental water temperature changes, the seawater temperature required by the cultured fishes needs to be continuously met, the angle and the depth of the water intake pipe need to be dynamically adjusted, and the water intake pipe is required to stably work at different depths; the deep seawater intake pipe can be impacted by ocean currents, the stability of the ship is threatened due to the difficulty in fixing the rigid deep seawater intake pipe, and the ship can fluctuate under the action of waves; the rigid water intake pipe is likely to hit the submerged reef in deep sea water, which affects the safety of the ship, so that the sonar sensor 8 and the compensation device are needed for prevention.
More specifically, the following is exemplified:
the length of the water taking pipe is about 70m, the top end of the water taking pipe is close to the bottom of the bow, and the bottom end of the water taking pipe is hung by a crane on a deck. The water intake pipe is placed on the main deck (one on each side of the port and the starboard) in a folded state, the water intake pipe is slowly placed into seawater by a crane in a culture working condition, and the temperature is measured by the temperature sensors at the bottom of the ship, the culture water tank and the tail end of the water intake pipe and then transmitted to the central processing unit for analysis and judgment. If the temperature of the ship bottom is suitable for the requirement of fish culture, the valve II 7 is closed, the valve I6 is opened, and only the seawater at the ship bottom is taken. When the temperature of the seawater in the culture water tank is higher or lower than the set temperature, the central processing unit measures the temperature of the end of the water taking pipe, the temperature of the bottom of the ship and the temperature in the culture tank through comparison, and the depth of the water taking pipe is controlled through the hydraulic crane. And simultaneously, the opening degree of a valve on a suction pipeline of the water taking pump is adjusted until the temperature of the seawater in the cabin reaches a set temperature. So that the temperature of the seawater in the cabin is always in the temperature range meeting the requirements of the cultured fishes. The water intake pipe is fixed at the water depth to continuously supply water to the culture water tank. When the water level in the cabin reaches the height of the overflow pipe, the seawater automatically overflows to the outboard to form a seawater circulating system. When the ship jolts under the action of waves or the water intake pipe swings under the action of ocean currents, the compensation device on the crane can compensate the jolting of the ship and the swinging of the water intake pipe, and therefore the threat to ship stability is eliminated. All valves in the system are electro-hydraulic remote control valves, and the opening of the valves can be automatically controlled. When the hydraulic power pipeline with the valve has a fault, the emergency hydraulic device can be used for operating and controlling the hydraulic power pipeline with the valve. Before the water intake pipe is put down, the sonar detection system needs to be opened firstly to continuously detect the underwater obstacles, so that the safety of the water intake pipe and the ship is ensured.
The above are preferred embodiments of the present invention, and those skilled in the art can make various changes or improvements on the above embodiments without departing from the general concept of the present invention, and these changes or improvements should fall within the scope of the present invention.
