HYDRAULIC POWER SYSTEM FOR A UTILITY VEHICLE
FIELD OF THE INVENTION
The present invention relates generally to a hydraulic power system for installation on a utility vehicle to enable use of hydraulically powered ancillary or auxiliary attachments for same, and more particularly to a hydraulic power system using the engine crankshaft as a primary drive input to operate one of a hydraulic pump and an alternator, and using a secondary shaft to drive the other one of the hydraulic pump and alternator.
BACKGROUND OF THE INVENTION
Utility vehicles are off road vehicles that have a side by side seating arrangement and generally have a higher payload or load carrying capacity than an ATV (All Terrain Vehicle). These vehicles are typically purchased by farmers, ranchers, commercial growers, landscapers, etc. and are used in place of larger tractors or construction equipment given their size and lower cost. However, one complaint is that these vehicles typically to not have the ability to run ancillary systems such as buckets, tillers, snow blower, sprayers, chippers, lawn mowers, etc.
There is a potential commercial opportunity for these systems as it provides a low cost alternative to the conventional larger systems.
The Kawasaki MuleTM is an example of a commercially available utility vehicle that does not have a factory-provided solution powering ancillary systems using hydraulics.
While there are some available add-on kits for the Mule the involve hydraulic power, including kits for a hydraulic bed and a hydraulic snow plow, the hydraulic power is achieved using a conventional electric-over-hydraulic power pack, in which a 12-volt DC brushed electric motor is powered by the electrical system of the vehicle and connected to a hydraulic pump and reservoir. In use of these system in other products, they have been found acceptable for low duty cycle, low power, linear hydraulic actuators that could run such accessories as a truck bed lift or snow plow blade. However, these systems have been found in some cases to fail if they are run continuously for notable periods of time, for example as little as 20 minutes.
Accordingly, applicant has developed a unique hydraulic power add-on for the Kawasaki Mule that is capable of providing reliable higher power output for extended periods, at least in part by relying on rotational input from the engine crankshaft instead of electrical power for operation of the hydraulic pump.

In typical cogeneration systems the main challenge is balancing the electrical and thermal load demands, where external sources are employed such as auxiliary fired boilers. In this process, the electrical and thermal loads are always in balance at all modes of operation. A
main feature of the process is the ability to control cogeneration efficiency by controlling the engine exhaust temperature (41) to the atmosphere. A second feature of the process is the ability to make up thermal heat demand by using electrical heating elements for thermal heat make up, where the electrical load for the heating elements is provided by the combustion engine. This feature demanding an increase in electrical output from the engine (23) and generator (24) simultaneously increases the output in waste heat generated which is recovered in heat exchangers 15 and 29. This combination of electrical and thermal supply maximizes the efficiency and use of the cogeneration unit. A third feature of this cogeneration process is the employment of variable speed pumps to meet and deliver the thermal load requirements at constant pre-set temperatures, traditionally these operate at a constant flow thus creating temperature swings. A fourth feature of the process is the mode of thermal energy recovery in this cogeneration process. Typically in cogeneration systems the main concern in the thermal energy recovery units is the corrosion and scaling caused by the dissolved gases and dissolved solids in the water circuit. This is due to the large temperature difference between the engine exhaust stream (can be as high as 750 F) and the heated water. In this cogeneration process, thermal oil is employed to recover the heat from the engine block (stream 21) and from the engine exhaust gas (stream 40) in a closed circulating loop. The heat is captured by the circulating thermal oil and is transferred in liquid/liquid heat exchangers to the heated water at much lower temperatures (200 ¨ 220 F) thus preventing and minimizing scale and corrosion.

[0014] The tri-generation method will now be described with reference to FIG. 2.
[0015] Referring to FIG. 2, a pressurized supply water stream 1 from a utility distribution or internal network enters the plant. A slipstream 2 of the cold water supply line is routed to cold water users. The water supply to the cogeneration system is routed through line 3 to pressure tank 4, where it is pre-heated by circulating thermal oil stream coil 34, exiting pressure tank 4 through line 5 into a second pressure tank 6 where it is further heated by circulating thermal oil stream coil 32. A temperature sensor transmitter 10 measures the temperature of the heated pressurized water atop of pressure tank 6, and sends a signal to temperature controller 9, where it is compared to a pre-set hot water operation temperature. If the temperature transmitted by sensor 10 is less than pre-set temperature of controller 9, the electric operated heating element 8 is modulated to heat the water in tank 6 to its pre-set temperature. When the water temperature in pressure tank 6 is greater than the pre-set temperature of controller 9, the electric heating element 8 turns off. The hot water stream 7 exits pressure tank 6 to users.
[0016] The heat to pressure tanks 6 and 4 is provided by a low pressure circulating closed loop thermal oil system. Thermal oil from receiver 11, is supplied through stream 12 to a variable speed pump 13, a temperature sensor transmitter 18 ensures the temperature of stream 22 is constant by transmitting the temperature to controller 20 which in turn controls the speed of pump 13, thus controlling the thermal oil flowrate 14 into heat exchanger 15, through coil 16 and exiting the heat exchanger through line17. Its purpose is to cool and control the combustion engine 23 closed loop oil system and maintain the lubrication oil at a constant pre-set temperature into the engine. The lubrication oil stream exits engine 23 through stream 21 into heat exchanger 15, where it is cooled by thermal oil coil 16 and returns back to the engine through line 22, a temperature sensor in line 22 ensures the flowrate of thermal oil to heat exchanger 15 is sufficient to keep stream 22 temperature constant at all combustion engine operating conditions. The heated thermal oil stream 17 goes through check valve 19 into stream 28 and enters exhaust heat exchanger 29. The thermal oil stream flows through coil 30 in heat exchanger 29 where it is further heated from engine exhaust stream 40. The cooling of engine exhaust stream 41 is controlled by a temperature sensor 20. The assembly of claim 19, wherein a specific section of the lower end piece comprises an inlet fitting connected to a pipe that passes through the specific section of the lower end piece to communicate with the middle chamber through an aperture.
21. The assembly of claim 1, wherein the cathode chamber comprises an outlet fitting connected to an tube that passes tangentially through a specific section of the upper end piece to communicate with the cathode chamber through an aperture and wherein the anode chamber comprises an outlet fitting connected to a tube that passes tangentially through a specific section of the upper end piece to communicate with the cathode chamber through an aperture.
22. The assembly of claim 21, wherein a specific section of the upper end piece comprises an outlet fitting connected to a pipe that passes through a specific section of the upper end piece to communicate with the middle chamber through an aperture.
23. The assembly of claim 1, wherein said ports address said spaces through said end pieces or through said electrode tubes adjacent to the site of insertion of said electrode tubes into said end pieces.
24. The assembly of claim 1, wherein said entrance ports direct the flow of said fluid at an angle of 0 to 15 degrees relative to the plane of said seats of said end pieces.
25. The method of claim 1, where the generated diluted Sodium Hydroxide as cleaning solution is suitable for cleaning all surfaces, including textiles, fabrics and carpets.
8 thermostat 62. A slipstream 54 from the glycol heating header 53 is routed through modulating temperature control valve 55, providing thermal energy to thermal chiller 56 through heated glycol coil 57, and routed to returning glycol header 42 for re-heating.
The chiller glycol returning header 59 discharges into glycol chiller storage tank 60. The glycol is fed through circulating pump 61 into chiller 56 where it is cooled in glycol chiller coil 62 to a pre-set temperature measured and transmitted by 63. Modulating controller 62 controls heated glycol thermal valve 55 to supply the thermal energy required for chiller 56.
[0020] A feature of this tri-generation system is the add-on to the cogeneration system in Fig. 1 where the same benefit of generating a continuous electrical and thermal load allows the combustion engine to generate both electrical and thermal loads in balance year around.
This is an added dimension for balancing electrical and thermal energy loads throughout all seasons. In cogeneration systems, the predominant energy requirement in the winter is thermal energy, whereas in the summer, the predominant energy load is electricity. Since both heating and cooling energy requirements are both driven at all seasons by both electricity and thermal energy, the proposed process meets the balance demand at all times.
[0021] Referring to FIG. 3, a variation on the tri-generation process where an ORC is employed to utilize thermal energy available from the combustion engine generator to produce additional electrical energy. This feature is an alternative to convert excess thermal energy into electrical energy. An ORC unit works on the principle of expanding and condensing a low boiling point fluid. A low boiling point fluid 68, is pumped to an high pressure (300 ¨ 600 psi) and heated up in heat exchanger 70 through coil 71. A
temperature transmitter 73, through controller 72, controls the temperature of the low boiling fluid stream 74 to vaporize it. The heated vapour stream enters 74 ORC expander/generator 75 and exits as a two phase stream 66 into a condenser and storage unit 67.
In this mode of operation electrical heating elements 8 and 50 are turned off, ORC unit is used for applications where thermal energy is abundant.
