Abstract

The invention discloses a remote control hydrodynamic water surface lifting device for an air gun array of a shallow water source ship, which comprises a water pump device arranged on the air gun array and a water spraying device arranged inside the head of the air gun array, wherein the water pump device can suck seawater and supply water to the water spraying device, and when the water pump device supplies water to the water spraying device, water flow sprayed by the water spraying device can lift the head of the air gun array. The water spraying device is arranged in the air gun array, and the water pump device is used for supplying water to the water spraying device, so that the water spraying device can spray water flow. By means of the reaction force of water flow impacting the water surface, the head of the air gun array is lifted, so that the head of the air gun array is prevented from colliding with the propelling pump at the stern, and the air gun array can be tilted to avoid the propelling pump, and damage is prevented.

Description

Air gun array remote control hydrodynamic water surface lifting device for shallow water seismic source ship Technical Field The invention relates to the technical field of source ships, in particular to an air gun array remote control hydrodynamic water surface lifting device for a shallow water source ship. Background Ocean reserves are rich in resources, and when people conduct ocean resource survey work, exploration source ships are usually used. A large number of specialized exploration equipment is placed on the deck of the exploration source vessel, which makes deck space extremely limited. The air gun array of the source ship is used as a source and needs to be placed below the water surface outside the ship, and high-intensity sound is emitted, and the process is called blasting. The air gun array is carried by the ship body, and is lowered into water after reaching the designated position, and is recovered to the ship after being used. In the recovery process of the air gun array of the shallow water source ship, the head of the air gun array is easy to collide with a propulsion pump below a slipway at the stern due to no obstruction under water, so that damage is caused. In view of the large volume and weight of the air gun array, if the air gun array is assisted on the ship by manpower to avoid collision, the air gun array is dangerous, consumes manpower and has low efficiency. Disclosure of Invention The invention provides an air gun array remote control hydrodynamic water surface lifting device for a shallow water source ship, which aims to overcome the technical problems. In order to achieve the above object, the technical scheme of the present invention is as follows: A remote control hydrodynamic water surface lifting device for an air gun array of a shallow water source ship comprises a water pump device arranged on the air gun array and a water spraying device arranged inside the head of the air gun array, wherein the water pump device can pump seawater and supply water to the water spraying device; when the water pump device supplies water to the water spraying device, the water flow sprayed by the water spraying device can enable the head of the air gun array to be lifted. Further, the water pump device comprises a compressed gas source and a water pump, wherein the compressed gas source is connected with an air inlet of the water pump, a water inlet of the water pump is positioned at the bottom of the air gun array, and a water outlet of the water pump is connected with the water spraying device through a pipeline.
