The driving device 204 enables the three-dimensional garage to store and retrieve cars. When the load potential energy changes during the process of storing and retrieving cars in the three-dimensional garage, the regenerated electric energy is transmitted to the inverter 203 through the driving device 204, and the inverter 203 transmits it to the electric energy feedback device 206. The electric energy feedback device 206 transmits it to the isolation transformer 205, and the isolation transformer 205 then transmits it to the external power supply 201. By setting up the energy recovery system 2, when the load potential energy changes during the process of storing and retrieving cars in the three-dimensional garage, the regenerated electric energy of the motor can be efficiently returned to the AC power grid for use by other surrounding electrical equipment. The power saving effect is very obvious, and the general power saving rate can reach 15%-45%. In addition, since the energy recovery system 2 is installed without a resistance heating element, the temperature of the computer room is significantly reduced, which can save the power consumption of the computer room air conditioner. In many occasions, saving the power consumption of the air conditioner often brings better power saving effects.

[0025] As a further improvement of the present utility model, the driving motor 101 is fixedly mounted on the supporting frame 8, the driving motor 101 is meshedly connected with the transmission gear 102, and a rotating dial 103 is fixedly arranged on one side of the transmission gear 102. A plurality of connecting wheels 104 form a rotating chain 3, and the rotating dial 103 is arranged at the bottom end of the rotating chain 3, and forms a rotating connection with the connecting wheel 104 at the bottom end of the rotating chain 3, and the rotating dial 103 is in the shape of a fan blade. A plurality of triangular plates 4 are arranged on one side of the rotating chain 3, and a side of the triangular plate 4 close to the rotating dial 103 is fixedly connected with two connecting wheels 104, and a tray assembly 5 is arranged on a side of the triangular plate 4 away from the rotating dial 103. By driving the motor 101, the transmission gear 102 can be controlled to rotate, thereby driving the rotating dial 103 to rotate, and the rotating dial 103 rotates the connecting wheel 104, so that the rotating chain 3 rotates in a predetermined track, so that the triangular plate 4 can realize vertical circular motion, and the triangular plate 4 drives the tray assembly 5 and the car placed on the car loading plate 504 of the tray assembly 5 to move the position, thereby realizing the storage and retrieval of the car in the vertical circulation type three-dimensional parking garage.

When the tray assembly 5 changes position, the triangular plate 4 is fixedly connected to the rotating chain 3, and the support shaft 501 and the triangular plate 4 are rotatably connected. The support shaft 501 will continuously adjust the angle of the tray assembly 5 as the triangular plate 4 rotates, so that the car on the vehicle loading plate 504 always maintains a normal vertical position on the ground.

[0027] As a further improvement of the present invention, the support frame 8 is mainly composed of four support columns 7, the transmission mechanism 1 is respectively arranged at the front and rear of the support frame 8, a protection box 6 is arranged outside the energy recovery system 2, and the protection box 6 is fixed on the support frame 8.

[0028] As a further improvement of the utility model, the electric energy feedback device 206 is mainly composed of KM3 contact, capacitor C charging circuit, VT1-VT6 inverter circuit, L1, C1 and L2 forming a passive filter, and KM2 contact. The DC bus terminal of the inverter 203 is connected to the electric energy feedback device 206. When the DC bus voltage reaches the set value of 680V, ​​the KM3 contact is turned on; the capacitor C is incorporated into the DC bus, and the regenerative energy generated by braking is stored in this capacitor to form a charging circuit; VT1 and VT6 are TA1 phase inverters, VT2 and VT5 are TA2 phase inverters, and VT3 and VT4 are TA3 phase inverters to form an inverter circuit; L1, C1, and L2 form a passive filter. When high-frequency harmonics pass through the L-type filter, due to the large frequency of the harmonics, the corresponding angular frequency ω is also large. At this time, the filter impedance Z=ωL is very large, which suppresses high-frequency harmonic currents; when the system is powered on, when the circuit breaker Q1 is closed, it is ensured that Q2 is in a closed state. The inverter current can return to the grid; when the system is powered off, when the circuit breaker Q1 is disconnected, ensure that Q2 is in a closed state, so that the inverter current can return to the grid before the frequency conversion circuit is cut off.

By arranging the guide wheel 9 to move in the guide track 10, the stability of the vehicle loading plate 504 during movement can be ensured.

[0030] When the utility model is used in practice, the driving motor 101 can be used to control the transmission gear 102 to rotate, thereby driving the rotating dial 103 to rotate, and the rotating dial 103 rotates and drives the connecting wheel 104, so that the rotating chain 3 rotates in a predetermined track, so that the triangular plate 4 can realize vertical circular motion, and the triangular plate 4 drives the tray assembly 5 and the car placed on the car loading plate 504 of the tray assembly 5 to move, thereby realizing the storage and retrieval of cars in a vertical circulation type stereo garage. When the load potential changes during the process of storing and retrieving cars in the three-dimensional parking garage, the regenerated electric energy is transmitted to the inverter 203 through the driving device 204, and the inverter 203 transmits it to the electric energy feedback device 206, and the electric energy feedback device 206 transmits it to the isolation transformer 205, and the isolation transformer 205 transmits it to the external power supply 201. By setting up the energy recovery system 2, when the load potential changes during the process of storing and retrieving cars in the three-dimensional parking garage, the regenerated electric energy of the motor can be efficiently returned to the AC power grid for use by other surrounding electrical equipment. The energy-saving effect is very obvious, and the general power saving rate can reach 15% to 45%. In addition, since the energy recovery system 2 is installed without a resistance heating element, the temperature of the computer room is significantly reduced, which can save the power consumption of the computer room air conditioner. In many occasions, saving the power consumption of the air conditioner often brings better power saving effects.
