Description

The object of the invention is a thermoelectric recuperative rope device with electric drive, resp. hybrid drive, which uses thermoelectric elements in the braking system of the retractor. Thermoelectric recuperative rope equipment is used mainly in the field of forestry, agriculture, construction and wherever it is necessary to approach the load in the phase of gravity approach down the slope.

BACKGROUND OF THE INVENTION

The hitherto known cable transport devices are not equipped with thermoelectric elements in the braking system of the winding device for the conversion of energy in the form of heat, which is generated during braking or braking. braking in the brake system, for electric energy.

Furthermore, the previously known cable transport devices for transporting loads do not use this energy in the form of heat generated in the braking system of the winding device. Generally, it causes a reduction in the efficiency of the brakes due to overheating. A known solution to this problem lies in the use of a back-up brake. These are most often currently solved on the aerodynamic and whirling principle.

In the field of recuperative rope equipment there is also known a solution according to patent application 53 - 2006 on the name recuperative rope equipment for timber harvesting. This recuperative rope cutter for timber harvesting, like the previous solutions, does not use thermoelectric elements in the brake system of the winding device.

SUMMARY OF THE INVENTION

The aforementioned drawbacks of the prior art approach of rope approach devices in heavy and steep inaccessible terrains are eliminated by the thermoelectric recuperative rope device using thermoelectric links in the brake system of the winding device.

SUMMARY OF THE INVENTION The thermoelectric recuperative rope device utilizes excess gravitational energy when approaching wood to generate electrical energy by thermoelectric cells. The charging of the traction battery is provided by a device which converts the energy in the form of heat generated in the brake system of the winding device (cable drum) into electrical energy. The winding system brake system is equipped with thermoelectric cells.

The thermoelectric recuperative rope device operates on the principle of continuous braking, resp. braking the truck to a constant desired speed. The recovery cable carriage with load is braked respectively. braked by the braking system in the retractor.

During braking, resp. braking in the brake system of the retractor generates energy in the form of heat. In the recuperative rope device according to the invention, this energy is utilized in the form of heat generated by braking in the braking system of the winding device. This energy in the form of heat, which is a loss energy for standard cable cars, is used to recharge the traction battery. This energy in the form of heat, which is wasted in the brake system of the winding device, is used to generate electrical voltage by means of thermoelectric cells (eg Peltier cells). These cells operate on the basis of the temperature difference and directly convert heat into electricity, which charges the accumulator during braking or braking. braking the cable car to a constant desired speed, especially during the gravity approach of the load down the slope.

Furthermore, the thermoelectric recuperative rope device simultaneously uses mechanical energy and energy in the form of heat, which arises during its operation, especially during the phase of gravitational approach of the load down the slope and subsequently converts it into electrical energy. The electricity thus obtained recharges the accumulator and is subsequently used in the phase of pulling the empty trolley back up the slope and to provide any other functions during operation of the recuperative rope equipment.
