Description

Hydraulic Supply for Generator Starting

The present invention relates to a hydraulic supply for starting a generator, and more specifically, to maximize the amount of hydraulic oil conveyance under the same vehicle weight, to simplify maintenance and repair, and to easily install a generator without damaging the road. It relates to a hydraulic supply for.

In modern society, electric energy is used in almost all fields and can be easily converted into a light source, a heat source, and a power source that are needed in daily life, and thus has a wide range of applications.

Such electric energy is generally produced by using hydro, thermal, and nuclear power. In order to produce electric energy through the existing power generation system, fossil fuel or other energy sources must be continuously supplied.

Therefore, in countries with high dependence on basic energy and lack of natural resources, most of the electric energy needed is imported by natural fuel and is obtained through the above power generation method.

On the other hand, the current popular electric energy generation method is to use thermal power generation or combined cycle power generation, which has the advantage of producing electricity stably, but is a harmful gas generated during the combustion of natural fuel, that is, gas or fossil fuel. As a result, environmental pollution such as NOx, CO, and CO ₂ is generated, thereby requiring new alternative energy.

In addition, the need for replacing increasingly depleted natural fuels in countries with high energy dependence and lack of resources is even more absolute.

On the other hand, in recent years, interest in wind power generation, which can solve environmental pollution problems and is relatively simple to install, has been increasing, but it has the advantage of being relatively economical and environmentally friendly. It is impossible to industrialize the masses because it cannot produce electric energy and can not be used in places with low air volume.

In addition, the above-described method can be installed only at the national level because it requires a large-scale power generation equipment, and minimal emergency measures with only a small amount of electricity when it is difficult to supply power through the transmission line or due to an accident. There is a need for a generator that can be used separately in places where it is necessary.

As a technology devised in consideration of such conditions, there is a "generator" filed on September 11, 2001 and filed and registered as a utility model No. 257033. This technology uses a plurality of clutches by using the weight and inertia energy of a running vehicle. And rotating the power generation shaft mechanically connected to the bevel gear to produce electric energy and to be used for traffic signals and other facilities.

That is, a pad assembly having a front pad 104 and a rear end pad 106 is installed through a frame assembly having a main frame 100 and an auxiliary frame 102, and a power transmission means is installed through the pad assembly. The power generation means is installed on the final shaft constituting the power transmission means.

And. The power transmission means includes a first drive shaft 110 mounted on the main frame so as to be rotatable, a first drive bevel gear 114 mounted via a first one-way clutch fitted on the first drive shaft 110, The second driving bevel gear 118 mounted on the first drive shaft 110 via the second one-way clutch and the bearings mounted on the auxiliary frame 102 are installed as well as the first and the second driving bevel gears. A driving bevel gear connecting shaft 122 engaged with the driving bevel gears 114 and 118 is provided.

In addition, the driving bevel gear connecting shaft 122 has a second driving shaft 124, a third driving bevel gear 126 provided through a second one-way clutch, and a first member fitted on the second driving shaft 124. The fourth driving bevel gear 128 and the driven bevel gear connecting shaft 130 meshed with the third and fourth driving bevel gears 126 and 128 are provided.

Therefore, when the front pad 104 is pressed by the wheels while the vehicle is running, the first driving shaft 110 is rotated in the same direction as the first rotation shaft 134, and the first driving shaft 110 is rotated by the rotational force transmitted to the first driving shaft 110. While the one-way clutch rotates counterclockwise, the first driving bevel gear 114 meshed with the one-way clutch also rotates counterclockwise, and the second drive bevel gear 118 rotates clockwise.

When the first and second driving bevel gears 114 and 118 are rotated, the driving bevel gear connecting shaft 122 engaged thereto rotates in the counterclockwise direction, so that the third and fourth driving bevel gears 126 and 128 rotate in the reverse direction, thereby driving the bevel. The final drive shaft 136 is rotated through the gear rotation shaft 130, and thus, the generator 138 connected to the final drive shaft 136 is operated to generate electricity.

However, the conventional power generation apparatus having the above structure has a drawback that not only power loss occurs in the power transmission process but also assembly and construction are inconvenient due to the structure in which a plurality of gears and drive shafts are interconnected and coupled. .

In addition, due to power loss inevitably generated during the power transmission process, the power generation capacity is lowered, the usability is lowered, and the device is damaged by rain or other foreign matters.

On the other hand, there is a conventional "hydraulic drive device for driving the generator" which is maintained as a utility model registered as No. 273659 dated December 20, 2002 as a hydraulic generator to compensate for the above disadvantages, which is driven by the pump rod It is configured to supply the power to reliably obtain the power required to start the generator.

When the vehicle passes over the hydraulic supply 200, the pad 202 is pressed by the weight of the vehicle, so that the roller 204 located below the pad 202 rotates counterclockwise and simultaneously the push lever 206 is pressed. Is rotated in a clockwise direction, the pump rod 208 is pressed, and when the pump rod 208 is pressed, pressure is applied to the fluid filled in the pump body 210, and the fluid compressed by the pressurized fluid flows through the pipe. It is stored primarily in the integrated tank.

In addition, the hydraulic motor installed in the generator is driven by using the high pressure fluid pressure collected by the fluid integration tank, and the generator is started. Since a plurality of pads are continuously pressed, the hydraulic pressure is continuously stored in the fluid integration tank to maintain the hydraulic motor. Can be driven continuously.

However, since the hydraulic drive device having such a structure is also installed on the road through which the vehicle passes, foreign matter introduced between the slot 216 and the pad 202 prevents the normal vertical movement of the pad 202. Since it is impossible to effectively transmit the rotational force to the push lever 206 due to an undesired operation, it is not possible to continuously supply the pressure oil through the pump rod 208, which raises a problem of not generating electric energy as the user intended.

In addition, since the hydraulic supply is installed through a frame in which several steel structures are connected to each other, assembling property is degraded, and a part of the road must be installed in the form of excavation and embedding, which leads to difficulties in construction and economic efficiency. There was also a problem.

The present invention devised to solve the above problems, can be easily installed on the ground without excavating the road, can maximize the amount of oil transfer, and is configured to simplify maintenance and repair, usability and power generation capacity It is an object of the present invention to provide a hydraulic supply for starting a generator improved.

Next will be described the operation and effect of the present invention hydraulic supply having the above structure.

The present invention is installed on the road where the traffic is frequent and operates the oil suction means and the oil discharge means through the piston 11 which is pressed when the vehicle passes over the device to continuously flow the hydraulic oil in the hydraulic tank into the hydraulic pump. The generator (not shown) connected to the pump is operated to produce electrical energy. When the oil is sucked and discharged, the oil suction means and the oil discharge means operate in the same manner as the check valves, respectively, thereby preventing reverse pressure of the hydraulic oil. .

That is, when the vehicle passes over the hydraulic supply, the piston 11 moves up and down while compressing the ball spring 19 by the vehicle load, and through the oil suction line 3 due to the pressure change generated in the block during the lift. The hydraulic oil in the tank flows into the block. At this time, the ball 45 moves downward by momentarily moving the ball while the ball spring 47 is pressed by the hydraulic oil to pass the hydraulic oil, and the hydraulic oil passed along the hydraulic oil passage 7 It is pumped to the oil discharge means.

Then, the ball 63 constituting the oil discharging means is turned on while moving upward in the upward direction while compressing the support spring 67 by the moving force of the pressure oil to convey the pressure oil to the oil discharge line (5), The oil moves through the oil discharge line 5 to a hydraulic pump, not shown, to start the generator, thereby producing electrical energy.

Meanwhile. As described above, when the oil pumping action occurs, the pressure oil introduced into the oil suction line 3 is not reversed. When the piston 11 descends, the pressure oil filled in the oil chamber 80 is compressed, thereby compressing the ball 45. The pressure oil movement is turned off because it is caught by the stopper 43, and on the contrary, the ball 63 is turned on because it is pushed up by the pressure oil.

In addition, since the movement of the ball 45 is regulated by the locking rod 49 when the oil suction line 3 is turned on, the ball 45 is not in the original position, thereby preventing the operation from being poor, and the cap 65. It is possible to effectively prevent the support spring 67 is separated by the discharge pressure by the protrusion 69 formed in the.

Preferred embodiments of the present invention are only intended to clearly describe and explain the purpose of the present invention. Of course, it can be used in a variety of design changes without departing from the scope and scope of the present invention described below.

As described above, according to the present invention, by supplying the hydraulic oil to the hydraulic pump connected to the generator via the piston lifted by the weight of the vehicle, it is possible to continuously produce electrical energy during the passage of the vehicle, and can be simply installed on the ground structurally The constructability is improved, and it is configured to simplify the maintenance work, which has the advantage of improving usability.
