Description
Technical Field
[0001] The utility model belongs to the technical field of ships, and in particular relates to a special electric push-tugboat for passing locks. Background Art
[0002] Non-powered vessels require the assistance of pushers and tugboats when passing through locks. Currently, there are two methods of pushing and tugboats used for passing locks: one is to tie the vessel to the side of the pusher and tugboat, and then the tugboat tows the vessel through the lock; the other is to push the vessel through with a pusher boat. Currently, there are no dedicated pushers for passing locks, and ordinary pushers and tugboats are used for passing locks. However, due to the other functions of pushers and tugboats, their overall size is large, resulting in a large turning radius, poor turning performance, and slow lock-passing efficiency. Utility Model Content
[0003] The utility model proposes a special electric push-tug boat for passing through a lock, which has a small overall size, a small turning radius and good turning performance, thereby improving the efficiency of passing through the lock.
[0004] To this end, the technical solution adopted by the present invention is: a special electric pusher and tugboat for passing through locks, comprising a main hull surrounded by a bilge and a main deck, a push frame being provided at the front end of the main hull, and a plurality of cable piles and handles being provided at intervals on the left and right sides of the main hull, the main hull being arranged from front to back as a bow tank, a hydraulic pump tank, a battery tank and a rudder and propeller tank, a power distribution room and a fire extinguishing room being provided at intervals on the left and right sides above the battery tank, a driving cab being provided above the hydraulic pump tank through a lifting device, and the driving cab being equipped with an inclined ladder accessed from the main deck, a straight-wing rudder and propeller device being provided in the rudder and propeller tank, a battery pack for providing power to the main engine of the straight-wing rudder and propeller device being provided in the battery tank, and a centralized control console for operating the straight-wing rudder and propeller device being provided in the driving cab.
[0005] As the preferred embodiment of the above scheme, the main hull is configured as a single bottom, single side, and single deck structure, the main hull's lines adopt a tugboat line type, the bilge includes the bottom and the side, the bottom and the main deck are both configured as a transverse frame type, the side adopts an alternating rib system, and the rib spacing is 500 mm.
[0006] Further preferably, two sets of straight-wing rudder-propeller equipment are arranged at left and right intervals in the rudder-propeller compartment, and two sets of straight-wing rudder-propeller equipment are arranged at left and right intervals in the battery compartment corresponding to the straight-wing rudder-propeller equipment.
[0007] Further preferably, the fire extinguishing chamber adopts a HFC-227ea fire extinguishing chamber, and a pipe network type HFC-227ea fire extinguishing system is provided in the battery compartment, and the main hull is equipped with a water fire extinguishing system.
[0008] Further preferably, a power supply socket box for external power supply and a shore power box for connecting to shore power are provided on the main deck.
[0009] The beneficial effects of the present invention are as follows: the entire vessel is dedicated to pushing and towing through locks, so that it does not need to be equipped with a living area, thus effectively reducing the size; at the same time, it is equipped with two sets of fully rotating straight-wing rudder propellers, so that the entire vessel has a large thrust and good rotation performance, thereby facilitating towing or pushing other ships; and the ship can be driven through the cab, so that the required personnel are reduced, saving labor costs; and the use of electric propulsion can basically achieve zero emissions and no pollution.

DETAILED DESCRIPTION
[0014] The present invention will be further described below with reference to the following embodiments and accompanying drawings:
[0015] like Figure 1-3 As shown, a special electric push tugboat for passing through a lock includes a main hull surrounded by a bilge 1 and a main deck 2. In order to push the ship through the lock, a pushing frame 3 is provided at the front end of the main hull. At the same time, a plurality of mooring piles 4 and handles 5 are arranged at intervals on the left and right sides of the main hull, so that the ship also has a tying and towing function.
[0016] The main hull is designed with a single bottom, single side, and single deck structure. The main hull's lines adopt the tugboat line type, which reduces the pusher's own resistance. The bilge 1 includes the bottom and side. The bottom and main deck 2 are both designed as transverse frames. The side adopts an alternating rib system with a rib spacing of 500mm. The superstructure and deck are steel transverse frame structures. The entire hull is equipped with several transverse bulkheads, of which the fifth, fourteenth, and eighteenth are watertight transverse bulkheads. They divide the main hull into the following from front to back: the forecastle tank A, hydraulic pump room B, battery room C, and rudder and propeller room D. That is, the area between the bow and the eighteenth transverse bulkhead is the forecastle tank, the area between the eighteenth and fourteenth transverse bulkheads is the hydraulic pump room, the area between the fourteenth and fifth transverse bulkheads is the battery room, and the area between the fifth transverse bulkhead and the stern is the rudder and propeller room.
[0017] To push the boat, a straight-wing propeller 7 is installed in the propeller compartment D. A battery pack, used to power the main engine in the straight-wing propeller 7, is located in the battery compartment C. To ensure the overall thrust of the boat, two straight-wing propellers 7 are spaced apart in the propeller compartment D, and two battery packs are located in the battery compartment C, corresponding to the left and right spacing of the straight-wing propellers 7. Preferably, the battery pack uses a conventional lithium iron phosphate battery system.
[0018] For ease of operation, a cab G is installed above the hydraulic pump compartment B via a lifting mechanism. Cab G houses a centralized control console for operating the straight-wing rudder propellers 7, enabling remote control of the entire pushboat from the cab. Cab G also features an inclined ladder 6, accessible from the main deck, with guardrails on both sides. Both the centralized control console and the lifting mechanism are conventional.
[0019] To prevent fires, a fire extinguishing room F is located above the battery compartment C. This room uses HFC-227ea fire extinguishing equipment, and a corresponding pipe-network HFC-227ea fire extinguishing system is installed inside the battery compartment C. To further prevent fires, the main hull is equipped with a water fire extinguishing system, including bilge fire pumps and fire hydrants on the deck, as well as other firefighting equipment such as fire extinguishers.
[0020] In order to facilitate the external power supply and docking of the battery compartment with shore power, a distribution room is provided above the battery compartment, and the distribution room is provided with a power supply socket box for external power supply and a shore power box for connecting to shore power.
[0021] The electric pushboat is also equipped with temporary emergency batteries, lighting systems, monitoring and alarm systems, navigation equipment, ventilation equipment, communication equipment, and existing technologies such as lightning protection and grounding.
