Abstract
The utility model discloses a natural gas gas engine direct drive is to boats and ships owner propulsion system of oar of coming about, a serial communication port, including natural gas gas engine, this natural gas gas engine is through the cardan shaft direct drive to the oar system that comes about. The utility model discloses there is following beneficial effect: 1, when the inland navigation craft size receives the restriction in narrow channel, do not change the width of a boat condition under, increase the captain, improve economic efficiency, and accomplish to have an easy control in the matter, 2, reduce harmful gas's emission, 3, improve propulsive efficiency, reduce the energy consumption, 4, solve gas engine suddenly with suddenly unloading the relatively poor weakness of performance, 5, simplify the construction, simple to operate.
Description
Technical field
The utility model relates to a kind of natural gas gas machine and directly drives the boats and ships basic propulsion system to the oar of coming about, and its dynamical system is placed on cabin or deck, connects full circle swinging to the oar of coming about by universal drive shaft.
Background technology
The basic propulsion system that is applied to boats and ships between inland waters, island has the diesel main engine of employing by gear-box deceleration rear drive constant pitch airscrew, this employing diesel oil is as the mode of fuel, the discharge of nitrogen oxide, oxysulfide, carbon dioxide and solid particle is all very serious, environmental pollution is very serious, and diesel oil cost is also high.
Also having the natural gas of employing gas machine is to drive spacing oar or adjustable propeller by gearbox shaft. Natural gas gas machine is the form that drives spacing oar by gearbox shaft, and sudden unloading process response is slower, and maneuvering performance is not so good; Natural gas gas machine drives adjustable propeller performance ideal, but cost is too high, and efficiency is on the low side.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of natural gas gas machine directly to drive the boats and ships basic propulsion system to the oar of coming about, to solve problem many in prior art.
To achieve these goals, the technical solution of the utility model is as follows:
Natural gas gas machine directly drives the boats and ships basic propulsion system to the oar of coming about, and it is characterized in that, comprises natural gas gas machine, and this natural gas gas machine directly drives the oar system of coming about by universal drive shaft.
In a preferred embodiment of the present utility model, the described arranged outside to the oar system of coming about has the protective grille of the protection played to the oar system effect of coming about.
In a preferred embodiment of the present utility model, described to arranging before and after two of the oar system of coming about blades, 5 leaves after first 4 leaves of blade, two oars are to turning.
The utility model has following beneficial effect:
1, when inland navigation craft size is subject to the restriction of narrow fairway, do not change in beam situation, increase captain, improve economic efficacy, and accomplish to have an easy control in the matter;
2, reduce the discharge of pernicious gas;
3, improve propulsive efficiency, reduce energy consumption;
4, solve the weakness of gas machine sudden unloading process poor-performing; 5, simplify construction, easy for installation, be applicable to Southeast Asia and build the regional Construction of ability.
Feature of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained and be well understood to.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the local enlarged diagram in Fig. 1.
Detailed description of the invention
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
Referring to Fig. 1 and 2, the utility model is a kind of boats and ships basic propulsion system that is applied to boats and ships between inland waters, island. This system comprises natural gas gas machine 1, the active force that natural gas gas machine 1 is whole system; Natural gas gas machine 1 directly drives the oar system 3 of coming about by universal drive shaft 2. To coming about, oar system 3 contains thrust bearing, change gear box. To arranging before and after two of the oar system of coming about blades, 5 leaves after first 4 leaves of blade, two oars are to turning, improve propulsive efficiency, oar footpath increases, and significantly reduces pitch ratio, oar load is little, reduces the external load fluctuation of gas machine, and to gas machine, to power, variable load responds high performance requirement in reduction.
The utility model has improved the problem of ship's manoeuverability under shallow draft completely, can increase captain, improves loading capacity. Due to the rotational characteristic to the oar of coming about, in special manipulation occasion, stop as anxious, fall back, racing, can easily realize, ensure safety, the weakness of gas machine sudden unloading process poor-performing is made up.
The arranged outside of the oar system 3 of coming about is had to the protective grille 4 of the protection played to the oar system effect of coming about. Prevent that the foreign matters such as fishing net from damaging rudder oar.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model. The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model. The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
