A self-locking device is arranged on a rotating shaft of a track wheel set 9 at the bottom of the gravity vehicle 3, and comprises a ratchet wheel 904, a pawl 905 and an electromagnet 906; a ratchet 904 is fixedly sleeved on a rotating shaft of the driving wheel above the support 903, a pawl 905 is arranged on the support 903, one end of the pawl 905 is movably hinged on the support 903, the other end of the pawl 905 is movably clamped in a tooth groove of the ratchet 904, and an electromagnet 906 is fixed on the support 903 above the pawl 905. The signal output end of the controller 12 is connected with the signal input end of the electromagnet 906 through a signal; when the electromagnet 906 is electrified, the pawl 905 is adsorbed by the electromagnet to be separated from the ratchet 904, and the self-locking device is unlocked; when the electromagnet 906 loses power, the pawl 905 falls under the action of gravity, the front end of the pawl 905 is clamped into the tooth groove of the ratchet wheel 904, the ratchet wheel 904 stops rotating, the self-locking device is locked, the rail wheel 901 stops rotating, the gravity vehicle 3 stops moving, the gravity vehicle 3 is protected, and the gravity vehicle is prevented from sliding downwards under the action of gravity to cause danger.
As shown in fig. 3, the signal output end of the power grid 10 is in signal connection with the signal input end of the monitor 11, the signal output ends of the monitor 11, the upper limit sensor 801, the lower limit sensor 802 and the speed position sensor 8 are in signal connection with the signal receiving end of the controller 12, and the signal output end of the controller 12 is in signal connection with the signal receiving ends of the electric/power generation all-in-one machine of the gravity vehicle 3, the high-order magnetic brake block 4, the low-order magnetic brake block 6 and the electromagnet 906.
The working principle is as follows:
the monitor 11 receives the index of AGC distribution and the index of the power generated by the maximum capacity of the wind farm in real time, and when the index of the power generated by the maximum capacity of the wind farm is equal to the index of AGC distribution, all the power generated by the wind farm is output to the power grid 10.
When the power generation index of the maximum capacity of the wind power plant is 50-60% larger than the AGC distribution index, the monitor 11 sends a signal to the controller 12, and meanwhile, the speed position sensor 8 also transmits the position and state information of the gravity vehicle 3 to the controller 12 through the signal; the controller 12 receives the signal and issues a command.
If the gravity vehicle 3 is in a low-position pre-energy storage state, the lower limit sensor 802 transmits a signal to the controller 12, the controller 12 controls the self-locking device to unlock after the controller 12 receives the signal, that is, the controller 12 controls the electromagnet 906 to be electrified, and when the electromagnet 906 is electrified, the electromagnet adsorbs the pawl 905 to be separated from the ratchet 904, so that unlocking is realized; meanwhile, the power supply of the low-level magnetic brake block 6 is cut off, then the controller 12 controls the power grid 10 to output the residual electric energy to the electric/power generation integrated machine, and the electric/power generation integrated machine drives the gravity vehicle 3 to move from the low level to the high level for storing energy.
If the gravity vehicle 3 runs in the middle section of the track 2 and no residual electric energy supports the gravity vehicle to continuously run to a high position for energy storage, when the speed position sensor 8 detects that the moving speed of the gravity vehicle 3 is reduced or even approaches zero, a signal is sent to the controller 12, the controller 12 controls the electromagnet 906 to be powered off, when the electromagnet 906 is powered off, the pawl 905 falls under the action of gravity, the front end of the pawl 905 is clamped into the tooth groove of the ratchet 904, the rotation of the ratchet 904 stops, the self-locking device locks, the rotation of the track wheel 901 stops, and the gravity vehicle 3 stops moving. Since the self-locking device locks the gravity vehicle 3, it cannot slide down the rail 2.
When residual electric energy supports the monitoring instrument to continuously operate to a high position for energy storage, the controller 12 controls the electromagnet 906 to be electrified after receiving a signal transmitted by the monitoring instrument 11, and when the electromagnet 906 is electrified, the electromagnet adsorbs the pawl 905 to be separated from the ratchet 904, so that the self-locking device is unlocked; meanwhile, the electric/power generation integrated machine is controlled to start, and the gravity vehicle 3 is continuously driven to store energy to run to a high position; until the gravity vehicle 3 reaches the highest position, the upper limit sensor 801 sends a signal to the controller 12 to prompt the gravity vehicle 3 to store energy; after receiving the signal, the controller 12 controls the power supply of the high-position magnetic brake block 4 to be switched on, and controls the self-locking device of the gravity vehicle 3 to be started, so that the gravity vehicle 3 is stable and immobile, and the energy storage of the gravity vehicle 3 is completed.
When the power generation energy of the maximum capacity of the wind power plant is smaller than an AGC distribution index, the monitor 11 sends a signal to the controller 12, and meanwhile, the speed position sensor 8 also transmits the position and state information of the gravity vehicle 3 to the controller 12 through the signal; after the controller 12 receives the signal, the self-locking device is controlled to be unlocked, if the gravity vehicle 3 is at the highest position, the upper limit sensor 801 transmits the signal to the controller 12, the controller 12 unlocks the self-locking device of the gravity vehicle 3, meanwhile, the controller 12 controls the high-position magnetic brake block 4 to be powered off, the gravity vehicle 3 does free-fall motion under the action of gravity, and the gravity vehicle runs along the track 2 from the high position to the low position to drive the electric/power generation integrated machine to rotate, so that the gravity energy is converted into electric energy to be output to the power grid 10. When the sensor 802 located at the lower limit is triggered, a signal is transmitted to the controller 12, and after the controller 12 receives the signal, the controller firstly controls the low-level magnetic brake block 6 to be electrified and started, then controls the self-locking device to be started, and the gravity vehicle 3 stops running and finishes discharging.
The utility model discloses only show a standard cell, if surplus electric energy or required electric energy is more, then start other unit process more than repeated, reduce the waste of electric energy, reach the purpose that improves the benefit.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
