The input shaft of each generator 117 is matched with the corresponding shifting gear 125 through a one-way transmission of the ratchet assembly 124, wherein the generator heat dissipation bracket 116 is fixedly matched with the guide slide bar connecting seat 122.

[0029] The switching assembly includes a partition support plate 105 fixed to the inner wall of the protective housing 103, a central gear stabilizing bracket 113 is fixed on the partition support plate 105, a central gear 112 is rotatably arranged at the center of the central gear stabilizing bracket 113, a magnetic limiting ring 108 is rotatably installed on the inner ring of the partition support plate 105, an outer ring double gear ring 109 is coaxially fixed on the magnetic limiting ring 108, the outer ring double gear ring 109 and the central gear 112 are meshed and transmitted through three planetary gears 111, and all the planetary gears 111 are rotatably installed on the planetary gear carrier 131. An electromagnetic limiting friction block sliding groove 106 is provided on the partition support plate 105, an electromagnetic limiting friction block 107 is slidably installed in the electromagnetic limiting friction block sliding groove 106 along the radial direction of the partition support plate 105, and the electromagnetic limiting friction block 107 and the magnetic limiting ring 108 are magnetically frictionally matched to limit the rotation of the magnetic limiting ring 108. The planetary gear carrier 131 in the switching assembly closest to the baffle 114 is fixedly matched with the guide slide connecting seat 122 and the generator heat dissipation bracket 116, and the planetary gear carrier 131 in the second switching assembly is fixedly synchronously driven with the central gear 112 in the switching assembly closest to the baffle 114 through a rotating shaft; the central gear 112 in the switching assembly farthest from the baffle 114 is fixedly matched with the output shaft of the light energy conversion drive motor 104. A linkage gear 110 is also rotated on the partition support plate 105 in each switching assembly, and the linkage gear 110 is meshed and driven with the corresponding outer ring double gear ring 109, wherein the linkage gear 110 is fixedly synchronously driven with the corresponding toggle gear 125 through a rotating shaft.

[0030] The working principle of a photovoltaic power generation and energy storage device disclosed in the present invention is as follows: according to different weather conditions and light intensity, the power generation of the solar panel 101 will change dynamically, especially in the evening or on cloudy days, the power generation of the solar panel 101 will be greatly reduced, so a storage device capable of storing these relatively weak electrical energies is needed. During the normal power generation process of the solar panel 101 (such as noon on a sunny day), the power generation of the solar panel 101 is the largest. The solar panel 101 transmits electricity to the light energy conversion drive motor 104 through a cable. A current and voltage sensor is provided at the output end of the solar panel 101 for real-time monitoring of the power generation power of the solar panel 101. When the light energy conversion drive motor 104 receives electricity, the output shaft of the light energy conversion drive motor 104 will rotate, and the light energy conversion drive motor 104 will rotate. The motor 104 drives the linkage gears 110 at different positions to rotate through the switching assembly, thereby driving the toggle gears 125 at the corresponding positions to rotate. The rotation of the toggle gear 125 will drive the rack 120 to move in the direction away from the guide slide rod connecting seat 122 (in this process, the toggle gear 125 will drive the outer ring of the ratchet assembly 124 to rotate. In this direction, the outer ring of the ratchet assembly 124 cannot drive the inner ring of the ratchet assembly 124 to rotate, and therefore cannot drive the input shaft of the generator 117 to rotate), and at the same time stretch the energy storage spring 121 to convert electrical energy into elastic potential energy of the energy storage spring 121. At the same time, no matter where the rack 120 moves to, the locking snap-in 126 provided on the rack 120 will contact and engage with different unlocking snap-in 127 to prevent the rack 120 from resetting and maintain the elastic potential energy of the energy storage spring 121.

[0031] According to the current power generation of the solar panel 101, the electromagnetic limiting friction blocks 107 in different switching components are controlled for adjustment. That is to say, if the electromagnetic limiting friction block 107 in a switching component is not working (only one electromagnetic limiting friction block 107 in all the switching components is not working, and only one electromagnetic limiting friction block 107 is in a non-powered state), the corresponding toggle gear 125 will rotate (because the electromagnetic limiting friction block 107 will not magnetically attract the magnetic limiting ring 108 when it is not working, thereby limiting the magnetic limiting ring 108, so the corresponding magnetic limiting ring 108 can rotate, and when the magnetic limiting ring 108 rotates, the outer double tooth ring 109 can rotate, thereby driving the corresponding linkage gear 110 to rotate, and then driving the corresponding toggle gear 125 to rotate). For example, the electromagnetic limiting friction block 107 corresponding to the switching component on the side closest to the baffle 114 is in an unpowered state, and all the remaining electromagnetic limiting friction blocks 107 are in a powered state. At this time, the output shaft of the light energy conversion drive motor 104 will drive the central gear 112 in the driving component on the side farthest from the baffle 114 to rotate, and the rotation of the central gear 112 will drive the planetary gear 111 to revolve, and the planetary gear 111 will revolve to drive the planetary gear carrier 131 to rotate, and the planetary gear carrier 131 will drive the central gear 112 in the next driving component to rotate, and so on, until it is transmitted to the side closest to the baffle 114. 14, and then because the central gear stabilizing bracket 113 in the driving assembly is fixed to the generator heat dissipation bracket 116, the central gear stabilizing bracket 113 cannot rotate, so that the central gear 112 drives the outer ring double gear ring 109 to rotate through the planetary gear 111, thereby driving the corresponding linkage gear 110 to rotate. Due to the deceleration of multiple switching components, when the power generation of the solar panel 101 is small in the working state at this time, the maximum torque is provided, thereby driving the rack 120 to pull the energy storage spring 121, so that its electrical energy is converted into elastic potential energy. On the contrary, when the power generation is large, the electromagnetic limiting friction block 107 in the switching assembly farthest from the baffle 114 is in a power-off state, and the planetary gears 111, the central gear 112, and the outer ring double gear ring 109 in all the remaining switching assemblies can be regarded as a whole and cannot rotate, so the corresponding planetary gear carrier 131 cannot rotate, and the power of the light energy conversion drive motor 104 can be directly transmitted to the outer ring double gear ring 109 through the central gear 112 and the planetary gear 111. The user can set the elastic force of different energy storage springs 121 to be different as needed, so that adaptive energy storage can be better performed.

[0032] When releasing electric energy, it is only necessary to energize the unlocking electromagnet 128 corresponding to the control, and then the unlocking electromagnet 128 attracts the unlocking bayonet 127, so that the elastic component 129 is compressed. At this time, the unlocking bayonet 127 will not restrict the locking bayonet 126, so that the rack 120 can be reset under the drive of the energy storage spring 121, and the movement of the rack 120 will drive the toggle gear 125 to rotate in a certain direction. The toggle gear 125 drives the input shaft of the generator 117 to rotate through the ratchet assembly 124, and then the generator 117 generates electric energy. During this process, all the electromagnetic limiting friction blocks 107 are in a power-off state. Therefore, a one-way transmission module is set between the toggle gear 125 and the linkage gear 110 to prevent the power of the toggle gear 125 from being transmitted to the linkage gear 110, to realize the one-way transmission of power, wherein the one-way limiting rotating disk 134 in the one-way transmission module is fixedly and synchronously connected to the toggle gear 125 side, and the one-way limiting friction shell 132 is fixedly and synchronously connected to the linkage gear 110 side. When the linkage gear 110 rotates, the one-way limiting friction shell 132 also rotates accordingly. At this time, the one-way limiting friction shell 132 drives the one-way limiting friction column 135 to move upward (in the direction of space reduction) on the inclined surface of the trapezoidal groove opened in the one-way limiting friction rotating block 133 through friction force. At this time, the inner wall of the one-way limiting friction shell 132 and the inclined surface of the trapezoidal groove squeeze the one-way limiting friction column 135 (the inclined surfaces of the trapezoidal groove are symmetrically arranged, and each inclined surface is contacted with a one-way limiting friction column 135). 135, so the two one-way limiting friction columns 135 are also symmetrically arranged). Since the two one-way limiting friction columns 135 are symmetrically arranged, no matter whether the one-way limiting friction shell 132 rotates clockwise or counterclockwise, one of the one-way limiting friction columns 135 will be squeezed, and the squeezed one-way limiting friction column 135 will be stuck between the one-way limiting friction rotating block 133 and the one-way limiting friction shell 132, thereby causing the one-way limiting friction shell 132 and the one-way limiting friction rotating block 133 to rotate synchronously. At this time, the one-way limiting friction column 135 drives the one-way limiting rotating disk 134 to rotate, which also drives the corresponding 125 to rotate. On the contrary, when 125 rotates, the one-way limiting rotating disk 134 rotates synchronously, and the one-way limiting rotating disk 134 rotates. The one-way limiting friction column 135 will be driven to rotate by the one-way limiting pin 137. The rotation of the one-way limiting pin 137 will cause one of the one-way limiting friction columns 135 to move downward on the inclined surface of the trapezoidal groove opened in the one-way limiting friction rotating block 133 (in the direction in which the space becomes larger). The other one-way limiting friction column 135 will make the same movement under the action of the friction force. At this time, the squeezing force of the one-way limiting friction shell 132 inner wall and the one-way limiting friction rotating block 133 on the one-way limiting friction column 135 disappears, and the friction force does not exist. Therefore, the one-way limiting friction rotating block 133 will idle in the one-way limiting friction shell 132, and the one-way limiting friction shell 132 will not be driven by the one-way limiting rotating disk 134, thereby realizing the cutting off of the transmission direction from the toggle gear 125 to the linkage gear 110.The elastic expansion rubber block 136 drives the two one-way limiting friction columns 135 to move in opposite directions, and maintains contact with the inclined surface of the trapezoidal groove provided on the one-way limiting friction rotating block 133 and the inner wall of the one-way limiting friction shell 132. The specific connection relationship is that a trapezoidal groove with symmetrical inclined surfaces is provided on the one-way limiting friction rotating block 133, and two one-way limiting friction columns 135 are symmetrically arranged on the inclined surface of the trapezoidal groove, and a one-way toggle limiting pin 137 is provided on one side of the two one-way limiting friction columns 135 facing the inclined surface of the trapezoidal groove, and the two one-way toggle limiting pins 137 are fixed on the one-way limiting rotating disk 134, and the one-way limiting rotating disk 134 is fixedly synchronously driven with the toggle gear 125, and the one-way limiting friction rotating block 133 is rotatably installed in the one-way limiting friction shell 132, and the one-way limiting friction shell 132 is fixedly synchronously driven with the linkage gear 110, and the two one-way limiting friction columns 135 are elastically matched through the elastic expansion rubber block 136.
