DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] For example, see Figure 1-Figure 9 , this embodiment provides a technical solution: a peak shaving and valley filling device, comprising an energy storage cabinet 1, in which a plurality of energy storage battery packs are installed for storing or releasing electric energy. A top plate 2 is fixedly provided on the top of the energy storage cabinet 1, and two symmetrically arranged longitudinal rain shields 4 are slidingly provided on the top plate 2 along its width direction, and the two longitudinal rain shields 4 extend along the length direction of the energy storage cabinet 1. A rotating shaft is rotatably provided on the side of the two longitudinal rain shields 4 away from each other, and there is damping between the rotating shaft and the longitudinal rain shield 4, which is used to increase the friction between the rotating shaft and the longitudinal rain shield 4. A rain guide plate 7 is fixedly provided on the rotating shaft, and the cross section of the rain guide plate 7 is a semicircular arc. Connecting rods 9 are symmetrically fixedly provided on both sides of the width of the top plate 2, and a rack 10 is fixedly provided on the connecting rod 9. Both ends of the rotating shaft pass through the corresponding longitudinal rain shield 4 and are fixedly provided with gears 8, and the gears 8 mesh with the corresponding racks 10 when in contact.

[0026] Two symmetrically arranged transverse rain shields 14 are slidably provided on the top of the top plate 2 along its length direction, and a driving assembly is provided on the top plate 2 for driving the two transverse rain shields 14 and the two longitudinal rain shields 4 to expand or contract respectively.

[0027] The bottom of the energy storage cabinet 1 is evenly fixed with a plurality of support columns, and the bottom of the support columns is fixed with a plurality of anti-skid protrusions. When the energy storage cabinet 1 is on a truck, the friction between the support columns and the truck is increased, making the energy storage cabinet 1 more stable.

[0028] The working principle of a peak shaving and valley filling device provided in this embodiment is as follows:

[0029] In the initial state, the gear 8 and the rack 10 are in meshing state.

[0030] When the driving assembly drives the longitudinal rain shield 4 to unfold, the gear 8 gradually moves away from the rack 10 and rotates under the action of the rack 10. The gear 8 drives the rain deflector 7 to rotate through the rotating shaft, so that the arc bottom of the rain deflector 7 rotates to the lowest position, and the damping between the rotating shaft and the longitudinal rain shield 4 maintains the angle of the rain deflector 7. When it rains, rainwater flows down along the top plate 2 and the longitudinal rain shield 4 into the rain deflector 7, and is guided by the rain deflector 7 to be discharged at both ends, so that the rainwater falls away from the heat dissipation holes of the energy storage cabinet 1, and avoids rainwater falling near the heat dissipation holes of the energy storage cabinet 1, thereby reducing the probability of splashing rainwater entering the energy storage cabinet 1 through the heat dissipation holes, and reducing the risk of short circuit of the battery pack in the energy storage cabinet 1, thereby increasing the safety of the energy storage cabinet 1.

[0031] For example 2, please refer to Figure 1-Figure 9 This embodiment proposes a technical solution based on the second embodiment: the driving component includes a motor 16, a mounting platform 15 is fixedly set at the top center of the top plate 2, the motor 16 is fixedly set on the top of the mounting platform 15, the output end of the motor 16 passes downward through the mounting platform 15 and is fixedly set with a central axis 17, a first winding wheel is fixedly set on the central axis 17, the first winding wheel is provided with winding grooves at both ends, a first traction rope 18 and a second traction rope 19 are respectively wound in the two winding grooves, the first traction rope 18 and the second traction rope 19 are respectively fixedly connected to the corresponding horizontal rain shield 14.

[0032] The bottom of the central axis 17 extends to the accommodating groove opened inside the top plate 2. A second winding wheel is fixedly installed at the bottom of the central axis 17. The second winding wheel is provided with two winding grooves, and the third traction rope 20 and the fourth traction rope 21 are respectively wound in the two winding grooves. The top plate 2 is symmetrically provided with through holes for the third traction rope 20 and the fourth traction rope 21 to pass through. The third traction rope 20 and the fourth traction rope 21 respectively pass through the corresponding through holes and are fixedly connected to the corresponding longitudinal rain shield 4.

[0033] Two symmetrically arranged slide grooves 11 are provided at the top of the top plate 2 along its length direction. A slider 12 is slidably arranged in the slide groove 11. The cross section of the slide groove 11 is T-shaped. The slider 12 is adapted to the slide groove 11 to prevent the slider 12 from being separated from the slide groove 11. The top of the slider 12 is fixedly connected to the transverse rain shield 14, and the transverse rain shield 14 is slidably fitted with the upper part of the top plate 2. A spring 13 is fixedly arranged between the slider 12 and the slide groove 11.

[0034] Both sides of the top plate 2 are inclined downward, and the inclined parts of both sides of the top plate 2 are symmetrically provided with slots 3, and the longitudinal rain shield 4 is slidably connected with the corresponding slots 3. A limit block 6 is fixedly arranged in the slot 3, and a limit groove 5 is symmetrically provided on the top of the longitudinal rain shield 4, and the limit groove 5 is slidably connected with the corresponding limit block 6. The rack 10 is arranged obliquely, and the inclination of the rack 10 is consistent with the inclination of the inclined part of the top plate 2. When the longitudinal rain shield 4 slides along the slot 3, the rack 10 is prevented from obstructing the rotation of the gear 8.

[0035] The working principle of a peak shaving and valley filling device provided by the utility model is as follows:

[0036] When in use, when the energy storage cabinet 1 does not need to be repaired, the motor 16 is first started, and the motor 16 drives the central shaft 17 to rotate, thereby rotating the first winding wheel and the second winding wheel, and the rotation of the first winding wheel and the second winding wheel respectively drives the first traction rope 18, the second traction rope 19, the third traction rope 20 and the fourth traction rope 21 to be released. At this time, under the action of the reset force of the spring 13, the slider 12 is pushed to slide outward in the slide groove 11, so that the two horizontal rain shields 14 are separated from each other and extend to the outside of the energy storage cabinet 1, protecting the two ends of the energy storage cabinet 1 from rain and sun. The two inclined longitudinal rain shields 4 slide downward under the action of gravity and extend to both sides of the energy storage cabinet 1, protecting both sides of the energy storage cabinet 1 from rain and sun.

[0037] When the energy storage cabinet 1 needs to be inspected and maintained, the output shaft of the motor 16 is reversed, and the motor 16 drives the central shaft 17 to rotate in the opposite direction, so that the first winding wheel winds and reels the first traction rope 18 and the second traction rope 19 respectively, so that the first traction rope 18 and the second traction rope 19 pull the two horizontal rain shields 14 closer to the middle and squeeze the spring 13. At the same time, the second winding wheel rotates to wind and reel the third traction rope 20 and the fourth traction rope 21 respectively, so that the two longitudinal rain shields 4 slide into the slot 3, and the gear 8 and the rack 10 are meshed during the sliding process, so that the gear 8 and the rack 10 drive the rotating shaft to rotate, and the rotating shaft drives the rain guide plate 7 to rotate upward and retract. This avoids the inconvenience caused by the unfolding of the horizontal rain shield 14, the longitudinal rain shield 4 and the rain guide plate 7.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
