Description

Technical Field

[0001] This application relates to the field of aquaculture and fluid transport engineering, specifically proposing a deep-water intake submersible pump backflushing device and an aquaculture vessel using the device. Background Technology

[0002] With the continuous development of large-scale deep-sea aquaculture facilities technology, especially with the increasing application of aquaculture workboats in the deep-sea aquaculture industry, the industry is showing multiple development directions, such as optimizing ship design, increasing the volume of aquaculture water on workboats, improving automation and aquaculture efficiency, and reducing aquaculture costs.

[0003] Because cold-water fish farming requires water from deeper waters, existing water transport facilities, especially large-scale systems such as those transporting water from the deep sea to ships or aquaculture platforms, necessitate large-diameter, long-distance water transport devices. However, the design of these existing technologies for lowering or retrieving pipelines from the ship does not meet current technical standards. For example, the stress at the connection point with the ship's side should be minimized, as the water pipe is subjected to ocean currents underwater, resulting in a large torque at its root relative to the ship's side connection. Furthermore, corresponding to the opposite direction of the hoisting ropes, the ocean current impact raises the water inlet position of the pipe, affecting the water intake depth.

[0004] Currently, the equipment configuration for aquaculture vessels has not effectively solved these problems. In view of this, this patent application is hereby filed. Utility Model Content

[0005] The deep-water intake submersible pump backwash device and its aquaculture vessel described in this application aim to solve the problems existing in the prior art by proposing a solution using a high-power submersible pump water intake mechanism and supplemented by multiple sets of dynamic balancing devices, in order to dynamically balance the torque of the submersible pump rotation and the torsional effect of ocean current impact on the water intake pipeline, thereby achieving stable and reliable deep-water intake operations.

[0006] To achieve the above design objectives, the deep water intake submersible pump backflushing device includes a water intake pipe with multiple sections connected to form a water delivery channel, and a submersible pump assembly connected to the inlet of the water intake pipe; the submersible pump assembly includes a pump casing sleeved on the water intake pipe, a drive assembly connected to the inner cavity of the pump casing through an array of fixing rods, and a first propeller drive connected to the output end of the drive assembly; on the pump casing at the outer edge of the inlet, an array of electric propeller assemblies with identical structures and the same number of sensors are symmetrically installed along the axial center of the water intake pipe through an array of brackets.

[0007] Furthermore, a first flange and a second flange are respectively provided at both ends of the pump casing. The first flange is fixedly connected to the outer periphery of the water intake pipe, and the second flange is fixedly connected to the outer edge of the water inlet.

[0008] Furthermore, the drive component is a submersible motor, a water pump, or an electromagnetic thruster.

[0009] Furthermore, the electric propeller assembly includes an electric propeller connector for a connecting bracket, a speed-regulating motor is installed on the electric propeller connector, the output end of the speed-regulating motor drives the connected propeller, and the speed-regulating motor communicates with a set of sensors through a signal line.

[0010] Furthermore, the rotation axes of the propellers in the array of electric propeller assemblies are all perpendicular to the rotation axis of the first propeller.

[0011] Based on the aforementioned deep-water intake submersible pump backwash device, this application proposes an aquaculture vessel, specifically wherein the deep-water intake submersible pump backwash device is connected to the deck inlet or the hull inlet via an elbow and a connecting pipe.

[0012] In summary, the advantages and beneficial effects of this application are that it can be applied to large aquaculture vessels or aquaculture platforms to transport water from deep sea areas to the vessel for aquaculture use. By using an array of electric spiral devices and sensors to dynamically balance the influence of external torque on the water intake pipe during operation through stepless speed regulation, the water intake position is stably maintained so as to keep the water intake depth and significantly improve the efficiency of deep water intake operations.

Detailed Implementation

[0021] Example 1: In deep-sea environments, aquaculture vessels need to draw water from the open ocean and transport it onto the ship for the cultivation of various aquatic products in the internal cabins. Since some fish species are cold-water aquaculture species, water needs to be drawn from deeper water layers. Especially for large aquaculture vessels, the water intake system must have a large-diameter, long-distance, and high-strength pipeline configuration.

[0022] like Figures 1 to 6 As shown, this application proposes a deep-water intake submersible pump backwash device, which is connected to the deck / hull water inlet 13 via an elbow 20 and a pipe 21. Specifically, the deck water inlet 13 is provided on the deck 11 of the aquaculture vessel 10, thereby enabling the entire aquaculture process from fry to harvest to be carried out inside the hull.

[0023] Specifically, the deck inlet 13 is fixed to the deck 11. The deck inlet 13 is connected to a set of water intake pipes 22 through an elbow 20 and a connecting pipe 21. Water intake operations are carried out from the deep sea area through the inlet 49 of the water intake pipes 22. The water intake pipes 22 can be made of a flexible material with good elasticity or a material with a more rigid upper part and a more flexible lower part.

[0024] The deep water intake submersible pump backwash device includes a water intake pipe 22 formed by connecting multiple pipe sections to form a water delivery channel, and a submersible pump assembly 30 is connected at the water inlet 49 of the water intake pipe 22.

[0025] The submersible pump assembly 30 includes a pump casing 31 sleeved on the water intake pipe 22. A first flange 35 and a second flange 36 are respectively provided at both ends of the pump casing 31. The first flange 35 is fixedly connected to the outer periphery of the water intake pipe 22, and the second flange 36 is fixedly connected to the outer edge of the water inlet 49.

[0026] The submersible motor 32 is connected to the inner cavity of the pump housing 31 via an array of fixing rods 34, and the first propeller 33 is driven and connected to the output end of the submersible motor 32;

[0027] On the pump casing 31 at the outer edge of the inlet 49, four sets of identical first electric propeller assemblies 40, second electric propeller assemblies 45, third electric propeller assemblies 50 and fourth electric propeller assemblies 55, as well as four sets of sensors are symmetrically installed along the axial center of the water intake pipe 22 via array brackets 37.

[0028] The first electric propeller assembly 40 includes a first electric propeller connector 43 on a connecting bracket 37. A speed-regulating motor 41 is installed on the first electric propeller connector 43. The output end of the speed-regulating motor 41 drives and connects to a second propeller 42. The speed-regulating motor 41 communicates with a first sensor 44 through a signal line.

[0029] The first electric propeller assembly 40 can preferably be a power component that generates auxiliary thrust water flow underwater, such as a water pump or an electromagnetic thruster.

[0030] Accordingly, the second electric propeller assembly 45 is connected to the second sensor 46, the third electric propeller assembly 50 is connected to the third sensor 51, and the fourth electric propeller assembly 55 is connected to the fourth sensor 52.

[0031] Moreover, the rotation axes of the propellers of the above four sets of electric propeller assemblies are all perpendicular to the rotation axis of the first propeller 33, thus forming an auxiliary power mechanism that surrounds the submersible pump assembly 30 in four directions.

[0032] like Figure 6 As shown, due to the large power of the submersible pump assembly 30, that is, the large torque of the submersible motor 32 when it starts working, the first propeller 33 will generate a clockwise or counterclockwise torque on the water intake pipe 22 due to inertia during the water intake operation. The magnitude and direction of the torque can be sensed by the above four sets of sensors, and the CPU drives one or more sets of electric propeller assemblies to start running to automatically balance the above torque and maintain the dynamic balance of the water intake pipe 22 to ensure that the water inlet 49 maintains a constant underwater depth.

[0033] Based on the same principle, when the direction and magnitude of the ocean current change significantly, causing obvious or large bends in the water intake pipe 22, the above four sets of sensors can still detect and trigger the CPU to drive the electric propeller assembly to start operation, so as to balance the impact of the ocean current.

[0034] In summary, the embodiments shown in the accompanying drawings are merely preferred solutions for achieving the objectives of this utility model. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this utility model. Other structural features derived therefrom should also fall within the scope of the solutions described in this utility model.
