Abstract
The utility model discloses a firefighting ship comprising a ship body, a water pump (1) and a mainframe (2) used for driving the ship body to sail, wherein the mainframe (2) is connected with the water pump (1); the firefighting ship further comprises a slip clutch (3), and the mainframe (2) is connected with a ship propeller (4) through the slip clutch (3). By adopting the firefighting ship disclosed by the utility model, a gearbox with a fixed reduction gear ratio in the prior art is changed, the slip clutch is used for changing the speed between the mainframe and the propeller, and the special structure of a slip gear box is used for reducing the load at the propeller end under a working state of the water pump so as to effectively the overload operation of the mainframe and guarantee the sailing security of the ship.
Description
Technical field
The utility model relates to the hull technical field, is a kind of fire boat specifically.
Background technology
On fire boat, generally all be provided with water pump, be used for fire extinguishing by the water pump water spray.Water pump is generally also by the hull host driven, and namely main frame also will drive pump working when driving the hull navigation, and water pump links to each other with the marine main engine free end by step-up gear.Undoubtedly, be under the non-operational configuration at boats and ships, the host driven water pump is nothing difficult naturally, but when the external fire-fighting of host driven fire pump, because under externally the powerful kick of fire water monitor affected, fire boat can fall back, and affects the fire-fighting effect.Therefore, this moment, main frame also needed to drive screw, and hull is positioned.Because the screw of our normal operation is the spacing oar, do not regulate the effect of load, main frame drives simultaneously water pump and screw will certainly cause the main unit load overload, damages easily main frame, affects boats and ships and uses.
The utility model content
The technical problems to be solved in the utility model is a kind of variable-speed clutch that adopts the propeller blades load to be provided, and effectively to avoid the fire boat of main frame overload operation.
Technical solution of the present utility model is, a kind of fire boat of following structure is provided, and comprises the main frame of hull, water pump and the navigation of driving hull, and described main frame is connected with water pump; Described fire boat also comprises slip clutch, and main frame is connected with propeller for vessels by slip clutch.
Adopt above structure, the utility model compared with prior art has the following advantages: adopt the utility model, change prior art and adopted the fixedly reduction box of speed reducing ratio, adopt the speed change between slip clutch realization main frame and the screw, in the situation of pump working, utilize the special structure of slippage gear-box, reduce the screw end load, thereby effectively avoided the main frame overload operation, ensured boats and ships enforcement safety.
Description of drawings
Fig. 1 is the structural representation of fire boat of the present utility model.
As shown in the figure 1, water pump, 2, main frame, 3, slip clutch, 4, propeller for vessels.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, fire boat of the present utility model comprises hull, water pump 1 and drives the main frame 2 that hull navigates by water that described main frame 2 is connected with water pump 1; Described fire boat also comprises slip clutch 3, and main frame 2 is connected with propeller for vessels 4 by slip clutch 3.
Described slip clutch 3 can adopt the slip clutch of Twin Disc Inc. (TWIN DISC) production of buying on the market.
Operation principle of the present utility model is as follows: the utility model has mainly utilized special " Ω " structure of Twin Disc Inc.'s slip clutch, change prior art and adopted the fixedly reduction box of speed reducing ratio, with the stepless time adjustment between slip clutch realization main frame and the screw, having in the situation of pump working, the load of corresponding reduction screw, thus the main frame overload operation effectively avoided.
Below only be described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model not only is confined to above embodiment, and its concrete structure allows to change.In a word, all various variations of doing in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
Claims (1)
1. fire boat, comprise hull, water pump (1) and drive the main frame (2) that hull navigates by water, described main frame (2) is connected with water pump (1), it is characterized in that: described fire boat also comprises slip clutch (3), and main frame (2) is connected with propeller for vessels (4) by slip clutch (3).
