Abstract

The invention discloses an air gun array remote control hydrodynamic water surface lifting device for a shallow water seismic source ship, which comprises a water pump device arranged on an air gun array and a water spraying device arranged in the head of the air gun array, and the water pump device can suck seawater and supply water to the water spraying device; 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. The head of the air gun array is lifted by means of counter-acting force generated when water flow impacts the water surface, so that the head of the air gun array is prevented from colliding with a propulsion pump at the stern, and the head of the air gun array can be tilted to avoid the propulsion pump to prevent damage.

Description

Technical Field

[0001] This invention relates to the field of seismic source vessel technology, and in particular to a remote-controlled hydrodynamic surface lifting device for an air gun array on a shallow-water seismic source vessel. Background Technology

[0002] The ocean is rich in resources, and when conducting marine resource exploration, humans typically use exploration seismic source vessels. These vessels require a large amount of specialized exploration equipment on their decks, making deck space extremely limited. The air gun array on the seismic source vessel serves as the seismic source, requiring it to be placed below the water surface outside the ship and emit a high-intensity sound; this process is known as firing the gun.

[0003] The air gun array needs to be carried by the hull. After arriving at the designated location, it is lowered into the water and then retrieved back onto the ship after use. During the retrieval process of the air gun array from the shallow-water seismic source vessel, due to the lack of underwater obstructions, the head of the air gun array is prone to colliding with the propulsion pump under the stern ramp, causing damage. Given the large size and weight of the air gun array, manually assisting it onto the ship to avoid collisions is not only dangerous and labor-intensive but also inefficient. Summary of the Invention

[0004] This invention provides a remote-controlled hydrodynamic water surface lifting device for an air gun array on a shallow-water seismic source vessel, in order to overcome the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A remotely controlled hydrodynamic water surface lifting device for a shallow-water seismic source vessel air gun array includes: a water pump device installed on the air gun array and a water spray device installed inside the head of the air gun array, wherein the water pump device is capable of drawing seawater and supplying water to the water spray device; When the water pump device supplies water to the water spraying device, the water jet from the water spraying device can lift the head of the air gun array.

[0006] Furthermore, the water pump device includes a compressed gas source and a water pump. The compressed gas source is connected to the air inlet of the water pump, the water inlet of the water pump is located at the bottom of the air gun array, and the water outlet of the water pump is connected to a water spraying device through a pipeline.

[0007] Furthermore, an electromagnetic check valve is provided between the compressed gas source and the air inlet.

[0008] Furthermore, the water spraying device is a water spray pipe with its outlet facing downwards.

[0009] Furthermore, the water spray pipe includes an inlet pipe and two outlet pipes symmetrically fixed on the inlet pipe. The outlet pipes are connected to the inlet pipe, and the end of the outlet pipe away from the inlet pipe is the outlet of the water spray pipe.

[0010] Furthermore, the angle between the axis of the inlet pipe and the axis of the outlet pipe is 45 degrees.

[0011] Furthermore, it also includes a remote control for controlling the water pump device.

[0012] Beneficial effects: This invention provides a remotely controlled hydrodynamic surface-lifting device for an air gun array on a shallow-water seismic source vessel. By installing a water spray device inside the air gun array and using a water pump to supply water to the spray device, the device can spray water. The reaction force of the water flow impacting the water surface lifts the head of the air gun array, thus preventing it from colliding with the propulsion pump and instead tilting it upwards to avoid damage.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This embodiment provides a remote-controlled hydrodynamic water surface lifting device for a shallow-water seismic source vessel air gun array, such as... Figures 1 to 6 As shown, it includes: a water pump device installed on the air gun array 1 and a water spray device installed inside the head of the air gun array 1. The water pump device is capable of drawing seawater and supplying water to the water spray device. like Figure 2 As shown, when the water pump device supplies water to the water spraying device, the water jet sprayed by the water spraying device can lift the head of the air gun array 1.

[0018] This embodiment provides a remotely controlled hydrodynamic water surface lifting device for a shallow-water seismic source vessel's air gun array. By installing a water spray device inside the air gun array 1 and using a water pump to supply water to the spray device, the device can spray water. The reaction force of the water flow impacting the water surface lifts the head of the air gun array 1, thus preventing a collision between the head of the air gun array 1 and the propulsion pump 6. Instead, the head is tilted to avoid the propulsion pump 6, preventing damage to the air gun array 1.

[0019] Specifically, such as Figures 3 to 5 As shown, the water pump device includes a compressed gas source 2 and a water pump 4. The compressed gas source 2 is connected to the air inlet 41 of the water pump 4 through a pipeline. The water inlet 42 of the water pump 4 is located at the bottom of the air gun array 1. The water outlet 43 of the water pump 4 is connected to a water spraying device through a pipeline. In this embodiment, the water pump 4 is fixed on the air gun array 1. The water pump 4 is a pneumatic pipeline pump. The compressed gas source 2 can be mounted on a ship or directly fixed on the air gun array 1 (in this case, the compressed gas source 2 can be a gas cylinder).

[0020] Specifically, such as Figure 5 As shown, an electromagnetic check valve 5 is provided between the compressed gas source 2 and the air inlet 41.

[0021] Specifically, such as Figures 1 to 5 As shown, the water spraying device is a water spray pipe 3 fixed on the air gun array 1, and the outlet of the water spray pipe 3 faces downward.

[0022] Specifically, such as Figure 6 As shown, the water spray pipe 3 includes an inlet pipe 31 and two outlet pipes 32 symmetrically fixed on the inlet pipe 31. The inlet pipe 31 is connected to the outlet 43 of the water pump 4 through a pipeline. The outlet pipes 32 are connected to the inlet pipe 31. The end of the outlet pipe 32 away from the inlet pipe 31 is the outlet of the water spray pipe 3.

[0023] Specifically, such as Figure 6 As shown, the angle between the axis of the water inlet pipe 31 and the axis of the water outlet pipe 32 is 45 degrees, so that the reaction force of the sprayed water flow can effectively support the head of the air gun array 1.

[0024] Specifically, it also includes a remote control for controlling the water pump device. The remote control can control the start and stop of the water pump 4 and the electromagnetic check valve 5. When retrieving the air gun array 1, the operators on board control the water pump device to start via the remote control, causing the water to spray downwards, so that the head of the air gun array 1 is like... Figure 2 The head of the air gun array 1 is tilted up; after the head of the air gun array 1 enters the slide 7, the operator controls the water pump to stop via remote control, so that the head of the air gun array 1 falls onto the slide 7.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
