For ease of the first drive mechanism, medium 5 is sent in higher memory container 1, the top of higher memory container 1 has
Opening, in the first drive mechanism, the first drive 31 is located in lower memory container 2, and the second drive 32 is located at higher memory
The overthe openings of container 1.First drive 31 is located in lower memory container 2 so that passing through first in the first bearing part 34
It is easy at driving wheel 31 and during being overturn contain the medium 5 in lower memory container 2 in first bearing part 34；The
Two drives 32 are located at the top of higher memory container 1 opening so that the first bearing part 34 is gone forward side by side at the second drive 32
It is easy to pour medium 5 in higher memory container 1 into during row upset.
The first conveyer belt in first drive mechanism is obliquely installed, the second drive 32 and switch valve 6 place vertical plane it
Between distance be less than the distance between the first drive 31 and switch valve 6 place vertical plane.As shown in figure 1, in direction shown in Fig. 1
On, when the first drive mechanism medium 5 is sent in higher memory container 1 by the left side of higher memory container 1, the first transmission
Band is tilted to the left setting that is to say, that the first drive 31 is in, with respect to the second drive 32, the position more keeping left.Now,
The second conveyer belt in second drive mechanism can be vertically arranged, that is, the 3rd drive 41 be located at the 4th drive 42 just under
Side.
Understand in the same manner, when medium 5 is sent to higher memory container by the right side of higher memory container 1 by the first drive mechanism
It is that the first driving-chain 33 is tilted to the right setting that is to say, that the first drive 31 is in more with respect to the second drive 32 in 1
The position kept right.
Move to switch valve 6 direction for the ease of the medium 5 in higher memory container 1, as shown in Fig. 2 higher memory is held
The inclined bottom surface setting of device 1, switch valve 6 is arranged at the region being in lower position on the bottom surface of higher memory container 1.So set
Meter, falls the medium 5 in higher memory container 1 and can move to lower along the bottom surface tilting, eventually arrive at switch valve 6, open
After switch valve 6, certain media 5 falls in the second bearing part 44, and other media 5 in higher memory container 1 may proceed to switch
Move at valve 6, thus ensureing when switch valve 6 is in opening, medium 5 constantly falls the second bearing part via switch valve 6
In 44.
In addition, the bottom surface of higher memory container 1 can also be the shape such as funnel-form or semicircle shape, switch valve 6
The region of extreme lower position is on bottom surface.
Move to the first drive 31 direction for the ease of the medium 5 in lower memory container 2, please continue to refer to Fig. 2, low
The bottom surface of position storage container 2 is arranged from the first drive mechanism diagonally downward at the second drive mechanism.So set
Put, during the second drive mechanism operating, falling in the second bearing part 44 in higher memory container 1, and hold with second
Holder 44 moves in lower memory container 2, and the medium 5 reaching in lower memory container 2 passes along the bottom surface tilting towards first
Moving in driving wheel 31 direction, thus avoiding accumulating excessively in the 3rd drive 41 lower dielectric 5, leads between medium 5 and driving-chain
The phenomenon that frictional force increases impact the second drive mechanism operating produces.
Move it is preferable that when medium 5 is solid in lower memory container 2 and higher memory container 1 for the ease of medium 5
During body, medium 5 is spherical structure, spherical medium 5 move mode in lower memory container 2 or higher memory container 1
For rolling, the frictional force producing each other is less, and translational speed is relatively faster.Further, can also hold in lower memory
Add lubricant, during medium 5 rolls, the surface of medium 5 can be stained with lubricant, enters in device 2 and higher memory container 1
One step reduces the friction between medium 5.Additionally, work as medium 5 to be contained from lower memory container 2 using the first bearing part 34
When, the friction between the first bearing part 34 and medium 5 is less, thus reducing the electric power in the first drive mechanism operation process
Loss, increased electric energy conversion ratio.
In electrical energy storage device, bearing part has multiple structural forms, and for example, bearing part can be pallet, specifically, pallet
Including loading plate, and it is arranged at the loading plate edge flange of a week, flange can be vertical or become certain angle between loading plate
Degree；Additionally, bearing part can also be for having the structure that body structure of opening etc. is capable of bearing medium 5 function.
In the present embodiment, drive mechanism is power-jdriven gear, and for example, drive mechanism can be blower fan.
Finally it should be noted that：Various embodiments above is only in order to illustrating the technical solution of the utility model, rather than it is limited
System；Although being described in detail to this utility model with reference to foregoing embodiments, those of ordinary skill in the art should
Understand：It still can be modified to the technical scheme described in foregoing embodiments, or to wherein some or all of
Technical characteristic carries out equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from this practicality new
The scope of type each embodiment technical scheme.
