[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0016] This embodiment is about a dual-purpose fire-fighting propulsion system for ships, which is used at the stern of a ship 1 and includes a dual-purpose system 2 and a propulsion motor 3 located in a power compartment at the stern of the ship 1. Figure 1 As shown, the dual-purpose system 2 and the propulsion motor 3 are both located at the stern of the hull 1 . The difference between the two arrangements is that the dual-purpose system 2 is located outside the hull 1 , and the propulsion motor 3 is located inside the hull 1 .
[0017] When the hull 1 of this embodiment is a speedboat, the propulsion motor 3 preferably has a power of 260-300 horsepower; when the hull 1 itself is an emergency rescue boat that requires more power, the number of dual-purpose systems 2 and propulsion motors 3 can be multiple sets, which is hereby explained.
[0018] In this embodiment, the dual-purpose system 2 includes a horizontally placed cylinder body 7, which is arranged below the waterline to ensure its contact with the water surface. A water contact suction port 12 and a water tank suction port 13 are provided on the lower side of the cylinder body 7. The water contact suction port 12 is always on the water surface. During actual use, in order to make the water absorption more stable, a swing-out hose can be provided at the water contact suction port 12. The water tank suction port 13 is connected to the water tank 14. A fire pump 15 and a water cannon 16 connected to the fire pump 15 are provided on the upper part of the water tank 14. The propulsion motor 3 is connected to the impeller 11 through the impeller shaft 8 and the coupling 10 extending into the cylinder body 7.
[0019] The propulsion motor 3 is located near the rear wall of the power cabin. By limiting its position, it is beneficial to shorten the overall length of the impeller shaft 8 and improve transmission efficiency and stability.
[0020] The dual-purpose system 2 also includes an auxiliary connecting block 4 and an anti-oxidation sleeve 5. A portion of the auxiliary connecting block 4 is connected to the cylinder body of the propulsion motor 3, and another portion of the auxiliary connecting block 4 is connected to the anti-oxidation sleeve 5. The anti-oxidation sleeve 5 is sleeved on the portion of the impeller shaft 8 between the cylinder body 7 and the propulsion motor 3. As the name suggests, the anti-oxidation sleeve 5 is used to prevent contamination of the impeller shaft 8 at the sleeve portion thereof. Figure 2 As shown, the auxiliary connecting block 4 is respectively connected to the cylinder body of the propulsion motor 3 and the anti-oxidation sleeve 5 by hinges, which facilitates adjustment of the axial extension error of the impeller shaft 8 during maintenance.
[0021] A head end seal 6 is provided between the anti-oxidation sleeve 5 and the cylinder body 7 to wrap the portion of the impeller shaft 8. The head end seal 6 is also implemented in a manner of blocking the inner cavity of the cylinder body 7. Specifically, the head end seal 6 is used to prevent water in the cylinder body 7 from entering the power compartment.
[0022] A rear end seal 9 is provided at the connection point where the impeller shaft 8 extends out of the cylinder body 7 . The rear end seal 9 is implemented in a manner of blocking the inner cavity of the cylinder body 7 . The rear end seal 9 corresponds to the head end seal 6 .
[0023] The water tank 14 is located at the stern of the hull 1 and directly above the dual-purpose system 2. In the non-firefighting application state, the water tank 14 is empty. From this, it can be understood that the ship fire-fighting and propulsion dual-purpose system disclosed in this embodiment is dual-function and single-use, that is, it is usually used to propel the hull 1, and the propulsion of the hull 1 is stopped when emergency firefighting is required.
[0024] There are multiple fire pumps 15, and each fire pump 15 is equipped with a water cannon 16. The fire pumps 15 and the water cannon 16 are both implemented in a manner higher than the main deck of the hull 1. In this embodiment, when there are multiple fire pumps 15, two are preferably used, and the water cannon 16 is equipped with a hose according to actual needs.
[0025] When emergency firefighting is required, the propulsion of the hull 1 stops, the fire pump 15 starts to operate and sucks water into the water tank 14 through the water contact suction port 12 and the water tank suction port 13 in sequence, and then sprays the water out through the fire pump 15 and the water cannon 16.
[0026] In this way, the dual-purpose fire-fighting and propulsion system for ships disclosed in the present invention combines the propulsion system and the fire-fighting system with each other and shares a common cylinder body, which has a streamlined structure, so that small ships are equipped with special equipment for fire-fighting, can obtain water on site, have a better fire-fighting effect, and completely get rid of the dependence on portable fire extinguishers.
[0027] The above-mentioned implementation manner is not a limitation of the present invention, and the present invention is not limited to the above-mentioned examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also fall within the scope of protection of the present invention.
