Description

Technical Field

[0001] This utility model relates to the field of water lifting technology for deep-sea submersibles, specifically a water lifting device for deep-sea submersibles. Background Technology

[0002] Traditional submersibles are used on the seabed for extended periods, requiring the collection and sampling of seawater at different depths. The collected seawater samples provide a direct reference for the seawater quality and geology of the area, offering detailed data for the development of marine industries. Sampling involves using a hoisting device to extend the device along a rail to a certain depth underwater or a certain distance from the submersible to collect water samples. However, due to the high pressure on the seabed, the efficiency of pumping water is not high.

[0003] Currently, the water extraction efficiency of water-lifting devices on submersibles is not high. For example, a smart water management integrated water quality sampling and testing device disclosed in CN117760797A includes a submersible and a sampling unit. This unit includes a water storage component located at the top of the submersible for storing collected water samples, and an adjustment component located inside the water storage component for controlling the entry of water samples into the component. When water is extracted from the first row of the first column of the inlet trough and the inclined block is inserted into the groove, the inclined block in the second row of the first column of the inlet trough is in contact with the inclined surface. At this time, the guide wheel is at the lower end of the first horizontal plate. When water sampling is required again, the principle is the same as the first water extraction process. When the second water sampling ends, the guide wheel transitions from the second inclined plate to the lower end of the second horizontal plate, and so on. This achieves the ability to collect water quality samples from multiple depths during a single submersible descent, resulting in high sampling and testing efficiency. However, the pumping and suction efficiency in this solution is insufficient, affecting the sampling efficiency of the water-lifting device.

[0004] Therefore, in order to address the above problems, the applicant needs to design a lifting device for launching and lowering deep-sea submersibles. Utility Model Content

[0005] The purpose of this invention is to provide a water-lifting device for deep-sea submersibles to solve the problem of insufficient water-drawing power in the water-lifting device mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a deep-sea submersible, comprising a main body, a rotating mechanism, and an inner cylinder. The rotating mechanism is provided on the side of the main body and is fixedly connected to a slider. The slider is slidably connected to a slide rail, which is stepped. The main body contains an inner cylinder and a water storage tank. The water storage tank and the inner cylinder are connected by a connecting rod. Multiple suction valves are installed at the bottom of the water storage tank, and all suction valves extend out from the bottom of the main body.

[0007] Furthermore, the plurality of water suction valves are arranged in a circular array about the center of the main body of the water inlet and outlet hoisting device, and the plurality of water suction valves can contact the water surface.

[0008] Furthermore, the rotating mechanism is provided with a gear and a bevel gear, which rotate coaxially and are meshed with a gear plate.

[0009] Furthermore, the bottom of the toothed plate can contact the pressure plate, which is annular and has multiple rubber balls at its bottom.

[0010] Furthermore, the positions of the plurality of rubber balls correspond to the positions of the plurality of water suction valves, and the diameter of the water suction valves is equal to the diameter of the rubber balls.

[0011] Furthermore, a rubber valve is slidably connected inside the inner cylinder. The rubber valve is annular, and its center is slidably connected to the inclined groove on the reciprocating screw via a sliding rod. The diameter of the rubber valve matches the inner diameter of the inner cylinder.

[0012] Furthermore, the rotating shaft at the bottom of the reciprocating screw is coaxial with the second bevel gear, and the second bevel gear meshes with the first bevel gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model sets a rotating mechanism on the main body of the water inlet and outlet hoisting device. By using the meshing of the gears and tooth plates of the rotating mechanism, the rotation of two bevel gears is driven, which causes the reciprocating screw and rubber valve in the inner cylinder to move up and down, generating pressure and allowing water to enter into multiple water suction valves.

[0015] 2. The meshing of the toothed plate and the gear drives the operation of two bevel gears. Simultaneously, as the toothed plate moves downward, it squeezes the extrusion plate and multiple rubber balls, increasing the water suction pressure in multiple water suction valves and improving the water suction efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, this utility model discloses a water-lifting and lowering device for a deep-sea submersible, comprising a main body 1, a rotating mechanism 2, and an inner cylinder 5. The rotating mechanism 2 is provided on the side of the main body 1 and is fixedly connected to a slider 3. The slider 3 is slidably connected to a slide rail 4, which is stepped. The main body 1 contains an inner cylinder 5 and a water storage tank 11. The water storage tank 11 and the inner cylinder 5 are connected by a connecting rod 8. Multiple water suction valves 12 are installed at the bottom of the water storage tank 11. The multiple water suction valves 12 extend out of the bottom of the main body 1 and are arranged in a circular array about the center of the main body 1. The multiple water suction valves 12 can contact the water surface.

[0024] By utilizing the connection between the inner cylinder 5, the water storage tank 11, and the suction valve 12, water can be drawn from multiple suction valves 12 into the water storage tank 11.

[0025] The rotating mechanism 2 is equipped with a gear 201 and a bevel gear 202, which rotate coaxially and are meshed with the gear plate 7. The positions of multiple rubber balls 10 correspond to the positions of multiple water suction valves 12, and the diameter of the water suction valves 12 is equal to the diameter of the rubber balls 10. A rubber valve 501 is slidably connected inside the inner cylinder 5. The rubber valve 501 is annular, and its center is slidably connected to the inclined groove on the reciprocating screw 502 via a sliding rod. The diameter of the rubber valve 501 matches the inner diameter of the inner cylinder 5.

[0026] As 7 pushes downward, it drives the meshing rotation of bevel gear 202 and bevel gear 6, which in turn drives the rotation of reciprocating screw 502 and the up-and-down movement of rubber valve 501, drawing water from multiple suction valves 12 into the water storage tank 11.

[0027] The bottom of the toothed plate 7 can contact the pressure plate 9. The pressure plate 9 is circular and has multiple rubber balls 10 at its bottom. The rotating shaft at the bottom of the reciprocating screw 502 is coaxial with the second bevel gear 6. The second bevel gear 6 meshes with the first bevel gear 202.

[0028] As the toothed plate 7 pushes downwards continuously, it will squeeze the pressure plate 9, causing multiple rubber balls 10 to be squeezed, increasing the pressure of multiple water suction valves 12 to draw water.

[0029] Working principle: First, the main body 1 of the water lifting device can be deployed underwater by sliding between the slider 3 and the slide rail 4;

[0030] By continuously pushing the toothed plate 7 downwards, the bevel gear 1 202 and bevel gear 2 6 are driven to rotate, causing the rubber valve 501 to start rotating. The rubber valve 501 will then move up and down inside the inner cylinder 5.

[0031] During the up-and-down movement, the valve inside the suction valve 12 is pulled, causing the suction valve 12 to start drawing water and drawing the water into the water storage tank 11.

[0032] As the toothed plate 7 continues to push downwards, the bottom of the toothed plate 7 will touch the pressure plate 9. After the multiple pressure plates 9 are squeezed, the suction force of the multiple suction valves 12 will increase, thereby improving the efficiency of water suction.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
