Description

Technical Field

[0001] This utility model relates to the field of propulsion device technology, specifically a propulsion device for marine bases. Background Technology

[0002] Maritime communication is an indispensable part of navigation activities, enabling ships to communicate promptly and accurately with land, other vessels, and maritime rescue organizations, ensuring safe and smooth navigation. The development of maritime communication technology has also provided crucial support and guarantees for maritime transportation, marine resource development, and maritime rescue.

[0003] Traditional maritime communication relies on shore-based base stations and radio stations near the coast, while satellite communication is generally used in the open ocean. This is costly and unreliable. Existing technologies utilize unmanned equipment as relay stations for maritime communication. This unmanned equipment includes, but is not limited to, unmanned communication vessels and unmanned communication buoys. These devices typically include a floating base at sea, equipped with photovoltaic or ocean current power generation devices to power the communication equipment. The base is usually secured by cables and can float within a certain range. To reduce the burden on the fixing equipment and to facilitate adjustments to the base's position and orientation, a propulsion device is installed at the bottom of the base.

[0004] However, unlike manned ships, offshore bases cannot be regularly returned to port for cleaning. Being submerged in seawater for extended periods can cause barnacles and other organisms to attach to the propulsion system, reducing its thrust and affecting its lifespan. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a propulsion device for marine bases.

[0006] The technical solution of this utility model is:

[0007] A propulsion device for a marine base, comprising:

[0008] The propulsion assembly includes a water spray assembly, which drives the base to move by pushing the water spray. The water spray assembly is provided with a reverse thrust assembly at its tail end. The water spray assembly is provided with a sealing assembly at its water inlet and outlet, which is used to seal the water spray assembly.

[0009] A protective component, the protective component including a drainage device for draining seawater from inside the water jet component.

[0010] Preferably, the water jet assembly includes a duct, the end of which is connected to a tailpipe, and a propeller assembly is provided inside the duct and the tailpipe, the propeller assembly being used to propel seawater.

[0011] Preferably, the thrust reverser assembly includes a thrust reverser cover, which is rotatably mounted at the tail end of the tail tube, and a first telescopic rod is connected between the thrust reverser cover and the tail tube.

[0012] Preferably, the sealing assembly includes a plurality of water inlet baffles, which are rotatably mounted on the inner side of the culvert head via a rotating shaft, and the water inlet baffles are connected to a second power source.

[0013] Preferably, the sealing assembly further includes several water outlet baffles, which are rotatably mounted on the inner side of the tailpipe end via a rotating shaft, and the water outlet baffles are connected to a third power source.

[0015] Preferably, a first liquid level sensor is provided on the side of the culvert head, and the first liquid level sensor is used to detect the liquid level height inside the culvert.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes a second and a third power source to drive the inlet and outlet baffles to rotate. When the propulsion assembly is not in operation, it can close the culvert and tailpipe to prevent marine life from entering the propulsion assembly. By controlling the angle of the outlet baffle, the direction of the water flow discharged from the propulsion assembly can be changed, facilitating the adjustment of the machine base's movement direction. When the inlet baffle is rotated to a vertical position, it facilitates the entry of seawater into the culvert while blocking larger debris from entering. Attached Figure Description

[0028] 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.

[0029] Example 1:

[0030] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0031] A propulsion device for a marine base, comprising:

[0032] The propulsion component 2 includes a water spray component, which drives the base to move by pushing the water spray. The rear of the water spray component is provided with a reverse thrust component, and the water inlet and outlet of the water spray component are provided with a sealing component 3, which is used to seal the water spray component.

[0033] The water jet assembly includes a duct 21, with a tailpipe 24 connected to the end of the duct 21. A propeller assembly is installed inside the duct 21 and the tailpipe 24, and the propeller assembly is used to propel seawater.

[0034] The propulsion assembly 2 is mounted on the base via a mounting bracket 1, which includes a mounting base plate 11 and a mounting back plate 12. The duct 21 is welded between the mounting base plate 11 and the mounting back plate 12, and both ends of the duct 21 pass through the mounting base plate 11 and the mounting back plate 12.

[0035] The propeller assembly includes a power source 22, which is fixedly mounted on the top surface of the mounting base plate 11. The output shaft of the power source 22 passes through the duct 21 and is fixedly connected to the propeller 23.

[0036] The power source 22 can be an electric motor. When the power source 22 is working, it can drive the propeller 23 to rotate, thereby pushing the seawater to move in the direction of the tailpipe 24. This, in turn, drives the base to move in the opposite direction.

[0037] The power source 22 can be powered by solar panels on the base or by an ocean current generator.

[0038] The thrust reverser assembly includes a thrust reverser cover 25, which is rotatably mounted at the tail of the tail tube 24, and a first telescopic rod 26 is connected between the thrust reverser cover 25 and the tail tube 24.

[0039] When the first telescopic rod 26 is working, it can drive the thrust shield 25 to rotate. When the thrust shield 25 is perpendicular to the tailpipe 24, it can block the water flow discharged from the tailpipe 24, thereby changing the direction of the water flow and driving the base to move towards the thrust shield 25.

[0040] The sealing assembly 3 includes several inlet baffles 32, which are rotatably installed on the inner side of the head of the culvert 21 via a rotating shaft 35, and the inlet baffles 32 are connected to a second power source 31.

[0041] The second power source 31 is a servo motor. The second power source 31 is fixedly installed at the head of the duct 21 by screws and is located above the mounting base plate 11.

[0042] When the second power source 31 is working, it can drive the water inlet baffle 32 to rotate through the rotating shaft 35.

[0043] When the inlet baffle 32 is rotated to the horizontal position, it can close the inlet of the culvert 21. When the inlet baffle 32 is rotated to the vertical position, it can facilitate the entry of seawater into the culvert 21, while blocking larger debris from entering the culvert 21.

[0044] The sealing assembly 3 also includes several water outlet baffles 34, which are rotatably installed on the inner side of the end of the tailpipe 24 via a rotating shaft 35, and the water outlet baffles 34 are connected to a third power source 33.

[0045] The third power source 33 is a servo motor, and it is fixedly installed above the end of the tailpipe 24 by screws.

[0046] When the third power source 33 is working, it can drive the water outlet baffle 34 to rotate through the rotating shaft 35.

[0047] When the outlet baffle 34 is rotated to be parallel to the outlet of the tailpipe 24, it can close the tailpipe 24. When the outlet baffle 34 is rotated to be perpendicular to the outlet of the tailpipe 24, it can facilitate the discharge of seawater from the tailpipe 24.

[0048] By changing the angle of the outlet baffle 34, the direction of the seawater discharged from the tailpipe 24 can be changed, thus playing a role in assisting steering.

[0049] In this embodiment, when the operator uses this equipment, the propulsion component 2 is installed at the bottom of the base using the fixing frame 1, ensuring that the inlet of the culvert 21 and the outlet of the tailpipe 24 are below the water surface.

[0050] Multiple propulsion components 2 can be installed.

[0051] When the base position needs to be adjusted, first control the second power source 31 and the third power source 33 to work, drive the inlet baffle 32 and the outlet baffle 34 to rotate, and release the seal on the propulsion component 2.

[0052] The power source 22 is controlled to operate, driving the propeller 23 to rotate, which pushes seawater out of the tailpipe 24, thereby moving the base.

[0053] By controlling the operation of the first telescopic rod 26, the thrust reverser shroud 25 can be lowered, thereby changing the thrust direction of the propulsion assembly 2 and achieving reverse thrust.

[0054] By changing the angle of the outlet baffle 34, the direction of the water flow ejected from the tailpipe 24 can be changed, thereby changing the direction of the thrust and facilitating the adjustment of the base position.

[0055] After the position adjustment is completed, first stop the propeller 23, then control the second power source 31 and the third power source 33 to drive the inlet baffle 32 and the outlet baffle 34 to rotate. This achieves the sealing of the duct 21 and the tailpipe 24.

[0056] After the duct 21 and tailpipe 24 are sealed, marine organisms can be prevented from attaching to the duct 21, tailpipe 24 and propeller 23.

[0057] Example 2: Reference Figure 1-3 ,

[0058] The protective component 4 includes a drainage device 41 for draining seawater from inside the water jet assembly.

[0059] The drainage device 41 uses a known water pump.

[0060] The inlet of the drainage device 41 is connected to a pumping pipe 42, and the end of the pumping pipe 42 is connected to the head of the culvert 21.

[0061] With the culvert 21 and tailpipe 24 sealed, the drainage device 41 is operated to pump seawater out of the culvert 21 and tailpipe 24 through the pumping pipe 42, further preventing barnacles and other organisms from attaching.

[0062] The first liquid level sensor 43 is provided on the side of the head of the duct 21.

[0063] The first liquid level sensor 43 is used to detect the liquid level in the culvert 21. When the liquid level is lower than the first liquid level sensor 43, the drainage device 41 stops working to prevent it from running dry.

[0064] The protective component 4 also includes a one-way valve 44, which is located above the tail end of the duct 21, and a second liquid level sensor 45 is provided on the side of the one-way valve 44.

[0065] The one-way valve 44 allows air to enter the culvert 21 when the drainage device 41 is working, facilitating drainage.

[0066] One-way valve 44 can also be used to inject water into culvert 21.

[0067] The second liquid level sensor 45 is used to detect the height of the liquid level inside the culvert 21.

[0068] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
