Description

Technical Field

[0001] The invention belongs to the technical field of gravity power generation, and in particular relates to a power generation device for a heavy-loaded vehicle to generate power when going downhill. Background Art

[0002] A heavy-load train generally refers to an extra-long, overweight freight train that uses large special freight cars and is pulled by two or more locomotives on transportation routes with concentrated freight arrivals and departures. Heavy-load trains have a large load capacity and a large number of vehicles.

[0003] When a heavy-loaded vehicle is going downhill, it generally uses a method of continuously braking to reduce speed, which not only wastes energy, but also easily damages the tires and durability of the vehicle, and has poor practicality. This phenomenon has become a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0004] The purpose of the present invention is to provide a power generation device for a heavy-load vehicle to generate power when going downhill in an existing material collection device, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a power generation device for a heavy-loaded vehicle going downhill, comprising a heavy-loaded vehicle and a ramp, characterized in that: the top of the ramp is an open structure, and the inner wall of the ramp is rotatably connected with a rotating shaft via a bearing, the outside of the rotating shaft is provided with a pulley via a key connection sleeve, a synchronous belt is sleeved between the two pulleys, the bottom of the heavy-loaded vehicle has wheels, and the wheels are in contact with the synchronous belt. When the heavy-loaded vehicle moves downward on the ramp, the brakes are first squeezed to stop the movement of the wheels. At this time, the wheels are attached to the synchronous belt and move downward due to gravity. Since the ramp has a certain slope, the gravity can have a downward component force. At this time, the synchronous belt will be driven to move due to the friction force of the wheels, thereby driving the two pulleys to rotate, and at this time, the rotating shaft can be driven to rotate to output the rotating torque. At this time, the gravity can be converted into rotational force, which is convenient for gravity recovery.

[0006] The present invention further illustrates that a support plate is fixed between the inner walls on both sides of the ramp by welding, and balls are evenly installed on the top of the support plate for rotation through a universal bearing. The balls are in contact with the inner side of the synchronous belt. When the synchronous belt is squeezed downward, it may cause bending of the synchronous belt. When the synchronous belt moves downward, it will be squeezed on each ball and slide relative to the ball, fully distributing the pressure to each contact point, thereby alleviating the pressure on the synchronous belt and preventing the synchronous belt from collapsing due to excessive pressure.

[0007] The present invention further illustrates that the synchronous belts have several groups, and the several groups of synchronous belts are arranged in a straight line along the surface of the ramp, and an intermediate dividing column is arranged between two of the synchronous belts. The two sides of the intermediate dividing column are fixed to the inner wall of the ramp by welding. In order to avoid the problem of excessive friction caused by the synchronous belts being too long, the synchronous belts are usually arranged at intervals. At this time, the empty area between the two synchronous belts can be filled and supported by the intermediate dividing column, thereby making the driving process of the heavy-loaded vehicle smoother.

[0008] The present invention further illustrates that a plurality of gear liquid pumps are installed in the ramp, one end of the rotating shaft is connected to the pumping gear of the gear liquid pump, a hydraulic motor is connected between the two ports of the gear liquid pump, and the output torque of the hydraulic motor is connected to a generator. When the rotating shaft is driven to rotate, the pump blade gear in the gear liquid pump will first rotate synchronously, and the liquid can be pumped at this time. All the liquid output by the gear liquid pump will enter the hydraulic motor, thereby driving the hydraulic motor to operate. The hydraulic motor converts the liquid pressure into torque and inputs it into the generator to recover the rotational energy and generate electricity. The advantage of this method is that the hydraulic energy of multiple rotating shafts can be superimposed and recovered, and there is no need to set up multiple generators, which effectively saves the number of structures of the electric energy recovery device and improves the energy utilization efficiency.

[0009] The present invention further illustrates that a two-position, two-way reversing valve is connected between the two ports of the hydraulic motor and the two ports of the gear liquid pump, and a hydraulic sensor is connected to an output end of the gear liquid pump. When the hydraulic motor is used, the pressure of the gear liquid pump port is sensed by the hydraulic sensor, thereby sensing the flow direction of the liquid. In a large downhill slope, there are often some vehicles going uphill. Some vehicles will also brake due to speed limit when going uphill, which will cause inertial friction between the tires and the synchronous belts. In the uphill section, the direction of the rotating shaft will be opposite, thereby making the flow direction of the gear liquid pump opposite. At this time, the reversing valve will be reversed according to the pressure felt in this section, so that the liquid will also enter the forward flow position of the hydraulic motor, so as to facilitate the recovery of the inertial potential energy of the vehicle in the uphill state of the downhill section.

[0010] The present invention further describes that a port of the gear liquid pump is connected to a valve component. When the valve component is used, the liquid in the gear liquid pump is first pumped into the valve component, and the valve component is used to control whether the liquid flows, thereby achieving the effect of regulating the liquid.

[0011] The present invention further illustrates that motor one and motor two are fixed to the two sides of the valve component respectively by welding, and the output ends of motor one and motor two are connected to nut sleeves, one end of the nut sleeve is connected to a screw rod by threading, and the screw rod moves through the inner wall of the valve component, and one end of the screw rod is fixed to a movable blocking block by welding. When motor one and motor two are started, the nut sleeves can rotate following their respective output shafts, so that the screw rod can perform translational movement, thereby adjusting the lateral position of the movable blocking block. When the movable blocking block is in contact with the side wall of the valve component, it is in a flow blocking state, and when separated, the liquid is in a natural flow state, which is convenient for adjusting the flow direction of the liquid according to needs.

[0012] The present invention further describes that a branch channel is opened inside the movable blocking block, main channels are opened on the inner walls on both sides of the valve member, and the main channel is connected with the branch channel, a buoyancy ball is provided on one side of the movable blocking block, a hollow cover is fixed to one side of the movable blocking block by welding, the density of the buoyancy ball is less than that of water, and the branch channel is located at the upper part of the movable blocking block, and the buoyancy ball is in contact with one end of the branch channel.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: in the present invention, a generator set is designed to be connected to the road surface or roadside on a downhill section of a highway, and the inertia of a heavy-loaded vehicle when going downhill is used to drive a belt at the same time. The belt is connected to a rotating wheel, and can drive the generator to generate electricity. When the vehicle goes downhill, the downhill speed can be controlled by the control system, which can effectively reduce accidents caused by brake failure of heavy-loaded vehicles on downhill sections, and the recovered electricity can be connected to the grid or stored separately.

DETAILED DESCRIPTION

[0022] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-6 The present invention provides a technical solution: a power generation device for a heavy-loaded vehicle going downhill, comprising a heavy-loaded vehicle 1 and a ramp, characterized in that: the top of the ramp is an open structure, and the inner wall of the ramp is rotatably connected with a rotating shaft 3 through a bearing, the outer part of the rotating shaft 3 is provided with a pulley 2 through a key connection sleeve, a synchronous belt 21 is sleeved between the two pulleys 2, the bottom of the heavy-loaded vehicle 1 has wheels, and the wheels are in contact with the synchronous belt 21. When the heavy-loaded vehicle 1 moves downward on the ramp, the brake is first squeezed to prevent the movement of the wheel. At this time, the wheel fits on the synchronous belt 21 and moves downward due to gravity. Since the ramp has a certain inclination, the gravity can have a downward component force. At this time, the synchronous belt 21 will be driven to move due to the friction of the wheel, thereby driving the two pulleys 2 to rotate, and at this time, the rotating shaft 3 can be driven to rotate to output the rotating torque. At this time, the gravity can be converted into rotational force, which is convenient for gravity recovery;

[0024] A support plate 4 is fixed between the inner walls of both sides of the ramp by welding, and a ball 41 is evenly installed on the top of the support plate 4 through a universal bearing for rotation. The ball 41 contacts the inner side of the synchronous belt 21. When the synchronous belt 21 is squeezed downward, it may bend due to the synchronous belt 21. When the synchronous belt 21 moves downward, it will be squeezed on each ball 41 and slide relative to the ball 41, fully distributing the pressure to each contact point, thereby relieving the pressure on the synchronous belt 21 and preventing the synchronous belt 21 from collapsing due to excessive pressure.

[0025] There are several groups of synchronous belts 21, and the groups of synchronous belts 21 are arranged in a straight line along the surface of the ramp. An intermediate dividing column 5 is arranged between two synchronous belts 21. Both sides of the intermediate dividing column 5 are fixed to the inner wall of the ramp by welding. In order to avoid the problem of excessive friction caused by the synchronous belt 21 being too long, the synchronous belts 21 are usually arranged at intervals. At this time, the empty area between the two synchronous belts 21 can be filled and supported by the intermediate dividing column 5, so that the driving process of the heavy-loaded vehicle 1 is smoother.

[0026] A plurality of gear liquid pumps 31 are installed in the ramp, one end of the rotating shaft 3 is connected to the pumping gear of the gear liquid pump 31, a hydraulic motor 91 is connected between the two ports of the gear liquid pump 31, and the output torque of the hydraulic motor 91 is connected to the generator 91. When the rotating shaft 3 is driven to rotate, the pump blade gear in the gear liquid pump 31 will first rotate synchronously, and the liquid can be pumped at this time. The liquid output by all the gear liquid pumps 31 will enter the hydraulic motor 91, thereby driving the hydraulic motor 91 to operate. The hydraulic motor 91 converts the hydraulic pressure into torque and inputs it into the generator 91 to recover the rotational energy and generate electricity. This has the advantage that the hydraulic energy of multiple rotating shafts 3 can be superimposed and recovered, and there is no need to set up multiple generators, which effectively saves the number of structures of the electric energy recovery device and improves the energy utilization efficiency.

[0027] A two-position, two-way reversing valve 8 is connected between the two ports of the hydraulic motor 91 and the two ports of the gear liquid pump 31. A hydraulic sensor 6 is connected to one output end of the gear liquid pump 31. When the hydraulic motor 91 is used, the pressure at the port of the gear liquid pump 31 is sensed by the hydraulic sensor 6, thereby sensing the flow direction of the liquid. In a large downhill slope, there are often some vehicles going uphill. Some vehicles will brake due to speed limit when going uphill, which will cause inertial friction between the tires and the synchronous belt 21. In the uphill section, the rotation direction of the rotating shaft 3 will be opposite, thereby making the flow direction of the gear liquid pump 31 opposite. At this time, the reversing valve 8 is reversed according to the pressure felt in this section, so that the liquid will also enter the forward flow position of the hydraulic motor 91, which is convenient for recovering the inertial potential energy of the vehicle in the uphill state of the downhill section.

[0028] One port of the gear liquid pump 31 is connected to a valve member 7. When the valve member 7 is used, the liquid in the gear liquid pump 31 is first pumped into the valve member 7, and the valve member 7 controls whether the liquid flows, thereby achieving the effect of regulating the liquid.

[0029] Motor 1 71 and motor 2 72 are fixed to the two sides of the valve member 7 by welding. The output ends of motor 1 71 and motor 2 72 are connected with nut sleeves 73. One end of the nut sleeve 73 is connected with a screw rod 74 by threading. The screw rod 74 movably passes through the inner wall of the valve member 7. One end of the screw rod 74 is fixed with a moving block 75 by welding. When motor 1 71 and motor 2 72 are started, the nut sleeve 73 can rotate along with their respective output shafts, so that the screw rod 74 can perform translational movement, thereby adjusting the lateral position of the moving block 75. When the moving block 75 is in contact with the side wall of the valve member 7, it is in a flow blocking state. When they are separated, the liquid flows naturally, which is convenient for adjusting the flow direction of the liquid according to needs.

[0030] A branch channel is provided inside the movable blocking block 75, and main channels are provided on the inner walls on both sides of the valve member 7, and the main channel and the branch channel are connected with each other. A buoyancy ball 77 is provided on one side of the movable blocking block 75, and a hollow cover 76 is fixed to one side of the movable blocking block 75 by welding. The density of the buoyancy ball 77 is less than that of water, and the branch channel is located at the upper part of the movable blocking block 75, and the buoyancy ball 77 is in contact with one end of the branch channel. Since the buoyancy ball 77 always floats on the upper part due to its lower density, the branch channel can be blocked by the buoyancy ball 77, but the liquid flowing into the inner cavity of the valve member 7 from the branch channel will not be affected, thereby achieving the effect of unidirectional conduction. The hollow cover 76 is used to limit the position of the buoyancy ball 77 while allowing it to continue to conduct liquid. When the movable blocking block 75 is attached to the inner walls on both sides of the valve member 7, the liquid flow must pass through one side of the buoyancy ball 77, so that the buoyancy ball 77 can be used to control the on and off of the liquid.

[0031] Embodiment 1: When the gear liquid pump 31 pumps liquid in the forward direction, the valve member 7 needs to be in a reverse check state. At this time, the left movable block 75 blocks the left wall of the valve member 7, and the right movable block 75 blocks the right wall of the valve member 7. At this time, the liquid will push the buoyancy ball 77 from left to right and allow the liquid to flow, which is suitable for the situation where the vehicle goes downhill;

[0032] Embodiment 2: When the gear liquid pump 31 pumps liquid in reverse, the valve member 7 needs to be in a forward non-return state. At this time, the right moving block 75 blocks the right wall of the valve member 7, and the left moving block 75 blocks the left wall of the valve member 7. At this time, the liquid will push the buoyancy ball 77 from right to left and allow the liquid to flow, which is suitable for the situation of deceleration and braking of the vehicle uphill;

[0033] Embodiment 3: When the non-return structure does not need to be controlled, the two moving blocking blocks 75 are both in a suspended state, at which time the liquid can flow unimpeded, which is suitable for the case where only downhill is considered.
