Description

Technical Field

[0001] This utility model is specifically a protective device for a submersible propulsion device, belonging to the field of propulsion technology. Background Technology

[0002] With the booming development of the global tourism industry, sightseeing in lakes and coastal areas has become a popular leisure activity. In order to meet tourists' demand for underwater exploration, sightseeing submarines that can dive into the water and observe underwater scenery have emerged. Sightseeing submarines are designed based on the design concept of submarines, but they are smaller in size and have a simpler structure and function, providing tourists with an underwater sightseeing experience. Among them, the propulsion unit is an essential accessory for the submarine.

[0003] Chinese Patent CN119611716B discloses an underwater sightseeing submarine, including a cockpit, an equipment compartment, a buoyancy tank, and a power mechanism. The cockpit is mounted on the equipment compartment, with a hatch on the top and multiple viewing windows on the side walls. The cockpit is equipped with a driving system, and the equipment compartment is equipped with an electromagnetic locking mechanism to fix the cockpit to the equipment compartment. This invention can quickly control the cockpit to detach from the equipment compartment and float to the surface in an emergency, completing an emergency escape and providing a more solid guarantee for the life and property safety of tourists.

[0004] Existing submersible thrusters are used in water. Due to the complexity of underwater conditions, in underwater operation scenarios, the environment itself contains complex factors such as aquatic plants and planktonic impurities. When the thruster is running, it also faces the situation that aquatic plants and other impurities in the underwater natural environment may attach and become entangled on the outside of the thruster, which will affect the stable operation of the propulsion system and affect the normal operation of the thruster. Utility Model Content

[0005] The purpose of this invention is to provide a protective device for submersible thrusters to solve the above-mentioned problems. This addresses the issue that, in the prior art, submersible thrusters also face the problem that impurities such as aquatic plants in the underwater natural environment may adhere to and become entangled on the outside of the thruster, thereby affecting the stable operation of the propulsion system and the normal operation of the thruster.

[0006] This utility model is achieved through the following technical solution: a protective device for a submersible propeller, comprising a propeller body, a baffle fixed to the outer side of the output shaft of the propeller body, a propeller sleeved on the outer side of the output shaft of the propeller body, a fastening cap screwed to the end of the output shaft of the propeller body, a protective mechanism provided on the outer side of the propeller, and an installation mechanism provided on the outer side of the propeller body.

[0007] Preferably, the protective mechanism includes a sleeve fixed to the outer side of the thruster body, a first baffle mesh sleeved on the outer side of the thruster body, a protective cover connected to one side of the first baffle mesh, a second baffle mesh connected to one side of the protective cover, L-shaped plates symmetrically fixed to the outer side of the second baffle mesh, a first screw hole penetrating one side of the L-shaped plate, connecting blocks symmetrically fixed to the outer side of the protective cover, a slot penetrating the middle of one side of the connecting block, and a first fastening bolt penetrating one side of the slot.

[0008] Preferably, the inner diameter of the first baffle is equal to the outer diameter of the propeller body, which facilitates the first baffle to fit against the outer side wall of the propeller body, and the first fastening bolt is screwed into the inside of the first screw hole, which facilitates the fixing of the L-shaped plate.

[0009] Preferably, the installation mechanism includes insertion holes evenly spaced along the edge of the protective cover, mounting cylinders evenly fixed along the outer side wall of the sleeve, a connecting rod slidingly passing through the middle of one side of the mounting cylinder, a connecting plate fixed to one end of the connecting rod, an insertion rod fixed to the bottom edge of the connecting plate, a mounting seat fixed to the other bottom edge of the connecting plate, a connecting rod rotating inside the mounting seat, a connecting ring sliding along the outer side wall of the sleeve, and a connecting seat evenly fixed to the outer side wall of the connecting ring.

[0010] Preferably, the installation mechanism further includes a second fastening bolt that penetrates and connects to the outer side of the connecting ring, and a second screw hole is provided on the outer side of the sleeve.

[0011] Preferably, the second fastening bolt is screwed into the inside of the second screw hole to facilitate the fixing of the connecting ring and prevent the protective cover from loosening. One end of the sleeve is fixed with a retaining ring to position the connecting ring, so that the second screw hole is aligned with the second fastening bolt, and at the same time prevent the connecting ring from falling off.

[0012] Preferably, the bottom end of the connecting rod is fixed with an anti-detachment plate, and the anti-detachment plate is located inside the mounting cylinder to prevent the connecting rod from separating from the mounting cylinder.

[0013] Preferably, one end of the connecting rod rotates inside the connecting seat. When the connecting seat moves, the connecting rod deflects, thereby moving the mounting seat, driving the connecting plate to move, and causing the insertion rod to move. The diameter of the insertion rod is equal to the diameter of the insertion hole, so that the insertion rod and the insertion hole fit together, which facilitates a stable connection.

[0014] This utility model provides a protective device for submersible thrusters, which has the following beneficial effects:

[0015] 1. This application utilizes a protective mechanism to install the protective cover and the first baffle. Then, an L-shaped plate is inserted into a slot, and the first fastening bolt is screwed into the first screw hole to fix the L-shaped plate, thereby installing the second baffle. The first baffle and the protective cover protect the outer side and inlet side of the propeller, preventing weeds and other impurities from contacting the propeller and thus preventing any impact on it, thereby improving the device's protective capabilities. Simultaneously, the second baffle further protects the propeller's drain outlet, enhancing the overall protective effect.

[0016] 2. This application, through the setting of the installation mechanism, welds the sleeve to the outside of the thruster body. By placing the protective cover on the outside of the thruster body, the first baffle mesh is made to fit against one side of the sleeve. Then, the insertion rod is aligned with the insertion hole, the connecting ring is pulled, the connecting seat is moved, and the connecting rod is deflected in the horizontal direction, causing the mounting seat to drive the connecting plate to descend, so that the insertion rod is embedded in the insertion hole. The second fastening bolt is screwed into the second screw hole to complete the connection. This facilitates the installation of the protective mechanism, making the installation simple and convenient for thrusters lacking protective measures, thus improving the practicality of the device.
