DETAILED DESCRIPTION

[0056] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0057] Since the entrance of a conventional protection box is relatively small, it is difficult to carry and replace the internal components, which results in the problem that it is troublesome to replace the components of the energy storage protection device of the conventional power station.

[0058] The present application provides an energy storage protection device for an energy storage photovoltaic power station, which aims to solve technical problems such as the difficulty in carrying the internal components of the energy storage protection device in the prior art. The present application enlarges the entrance of the protection device and provides a flip cover structure that can be freely rotated to open or close, so that the internal components can be easily replaced and carried. At the same time, a restraining frame structure is provided. After the internal components are replaced, the restraining frame structure can better lock the flip cover, making it difficult to open, and ensuring that the protection device can be carried stably and safely.

[0059] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0060] Figure 1 A schematic diagram of the structure of the energy storage protection device of the energy storage photovoltaic power station provided in this application.

[0061] like Figure 1 As shown, the energy storage protection device includes: a telescopic component 1, a chassis 2, a flip cover 3, a restraining frame 4 and a bolt 5;

[0063] Those skilled in the art can understand that the telescopic component 1 can be hydraulically telescopic, elastically telescopic, etc., and the closing and opening of the flap 3 and the chassis 2 are mainly achieved by the telescopic component 1; one end of the telescopic component 1 is arranged in the chassis 2, and can be detachably connected to the chassis 2 or fixedly connected, and the other end is connected to the flap 3. In this embodiment, the connection method of the telescopic component 1 and the chassis 2 and the flap 3 is not limited;

[0064] The flap 3 at the front end of the chassis 2 can be opened or closed, and the upper end of the flap 3 is rotatably connected to the chassis 2 by means of hinges, bearings, locking bolts, etc., so that the flap 3 can be opened or closed with the upper end of the flap 3 as the axis.

[0065] A restraining frame 4 is provided at the lower end of the chassis 2; a bolt 5 is detachably inserted into the restraining frame 4 and detachably threadedly connected to the chassis 2; and an upper end of the restraining frame 4 is detachably clamped to a lower end of the flip cover 3.

[0066] A restraining frame 4 is provided at the lower end of the chassis 2. When the flip cover 3 is closed, the restraining frame 4 fixes the bottom of the flip cover 3. The restraining frame 4 is used to achieve stability after the flip cover 3 is closed. At the same time, the flip cover 3 is not easy to open, ensuring that the internal components of the energy storage protection device will not fall out and be damaged during the movement of swinging.

[0067] Furthermore, the bolt 5 is detachably inserted into the restraint frame 4 and is detachably threadedly connected to the chassis 2, and the flip cover 3 is firmly connected to the chassis 2 through the bolt 5; the upper end of the restraint frame 4 and the lower end of the flip cover 3 are detachably clamped, and when the flip cover 3 is closed, the upper end of the restraint frame 4 is clamped to the lower end of the flip cover 3, and then the bolt 5 is used to connect, so as to achieve the stability of the energy storage protection device.

[0068] During the specific implementation process, first, the telescopic component 1 pushes and rotates the flap 3 to open it, and places the energy storage element and other devices into the energy storage protection device. Then, the flap 3 is closed, and the upper end of the restraining frame 4 is clamped on the lower end of the flap 3. Then, the bolts 5 are used to connect the flap 3 and the chassis 2 to complete the installation.

[0069] When the flip cover 3 is rotated and opened, the front opening of the box body 21 is no longer blocked, and the components inside the box body 21 are moved out and new components are moved in, thereby increasing the transport operable range through the front opening of the box body 21.

[0070] The embodiment of the present application provides an energy storage protection device for an energy storage photovoltaic power station, which comprises a telescopic component, a chassis, a flap, a restraining frame and a bolt; a flap is provided at the front end of the chassis; the upper end of the flap is rotatably connected to the chassis; one end of the telescopic component is provided in the chassis, and the other end is connected to the flap; a restraining frame is provided at the lower end of the chassis; the bolt is detachably inserted into the restraining frame and detachably threadedly connected to the chassis; the upper end of the restraining frame is detachably clamped with the lower end of the flap.

[0073] The first guide sleeve 23 is fixed on the outer surface of the bottom end of the opening of the box body 21, and the first guide sleeve 23 is used to connect the restraining frame 4; of course, there can be one or more first guide sleeves 23. When there is only one first guide sleeve 23, the first guide sleeve 23 can be on the left or right end of the outer surface of the bottom end of the opening of the box body 21, so that the restraining frame 4 is clamped on the bottom end of the flip cover 3 and connected with the bolt 5; when there are multiple first guide sleeves 23, they can be evenly distributed on the outer surface of the bottom end of the opening of the box body 21.

[0074] The second bearing seat 24 is fixed to the outer surface of the top opening of the box body 21; the second bearing seat 24 has one or more; if there is one second bearing seat 24, the second bearing seat 24 is fixed as a whole to the outer surface of the top opening of the box body 21; if there are two second bearing seats 24, the second bearing seats 24 are fixed to the left and right ends of the outer surface of the top opening of the box body 21. The specific number of the second bearing seats 24 is not particularly limited in this embodiment;

[0075] The upper end of the flip cover 3 is rotatably connected to the second bearing seat 24, and the restraining frame 4 is slidably connected to the first guide sleeve 23. The flip cover 3 can rotate freely around the second bearing seat 24 as an axis, and the restraining frame 4 is slidably connected to the first guide sleeve 23 by means of a cone sleeve, a sliding pin, etc. When the flip cover 3 is closed, the restraining frame 4 is connected to the first guide sleeve 23 to stabilize the energy storage protection device; when the flip cover 3 is to be opened, the restraining frame 4 is first disassembled, and then the flip cover 3 is rotated to open.

[0076] Furthermore, the chassis 2 is further provided with two first bearing seats 22; the two first bearing seats 22 are symmetrically fixedly arranged on the inner side wall of the chassis 2; Figure 1 As shown, the first bearing seat 22 is detachably connected to the telescopic component 1, and the telescopic component 1 enables the flap 3 to be opened; the telescopic component 1 is telescoped by hydraulic pressure or elasticity.

[0077] Figure 3 This is a schematic diagram of the flip cover structure of the energy storage protection device of the energy storage photovoltaic power station provided in this application. Figure 3 As shown, in another embodiment, the flip cover 3 includes a rotating shaft 31 and a cover plate 32; the rotating shaft 31 is fixedly arranged on the upper end of the cover plate 32; the rotating shaft 31 is plugged into the second bearing seat 24;

[0078] The flip cover 3 is an integrally formed component, including a rotating shaft 31 and a cover plate 32. The rotating shaft 31 is fixedly arranged on the upper end of the cover plate 32. The cover plate 32 is used to close the box body 21, thereby protecting the energy storage element and the like from damage; and the rotating shaft 31 is inserted into the second bearing seat 24, so that the flip cover 3 can rotate around the rotating shaft 31 as the axis.

[0079] In order to enable the flip cover 3 to be inserted on the second bearing seat 24 and rotate freely, an avoidance hole 33 is provided on the flip cover 3 . When the flip cover 3 rotates around the rotation axis 31 , the avoidance hole 33 avoids the second bearing seat 24 .

[0080] Figure 4 This is a schematic diagram of the structure of the restraining frame of the energy storage protection device of the energy storage photovoltaic power station provided in this application. Figure 4 As shown, in yet another embodiment, the restraining frame 4 includes a restraining bar 41 and a sliding post 42;

[0081] The slide post 42 is fixedly disposed at the bottom end of the restraining strip 41 ; the slide post 42 corresponds to the first guide sleeve 23 , and the slide post 42 can be inserted into the first guide sleeve 23 .

[0082] The restraint frame 4 has a restraint bar 41 and a slide post 42 . The slide post 42 is fixedly arranged at the bottom end of the restraint bar and corresponds to the first guide sleeve 23 . The slide post 42 can be inserted into the first guide sleeve 23 to fix the restraint frame 4 , the flip cover 3 and the box body 21 .

[0083] Furthermore, the restraining frame 4 further comprises a retaining ring 43 and a second guide sleeve 44 ; the second guide sleeve 44 is fixedly arranged in the middle of the restraining strip 41 ; and the retaining ring 43 is fixedly arranged at the front end of the second guide sleeve 44 .

[0084] like Figure 4 As shown, in another embodiment, the bolt 5 includes a threaded rod 51 and a knob 53; the threaded rod 51 and the knob 53 are fixedly connected; the threaded rod 51 passes through the retaining ring 43 and the second guide sleeve 44, and is threadedly connected to the screw hole 25 on the chassis 2, so as to fix the restraining frame 4 to be installed on the chassis 2.

[0085] Figure 5 A schematic diagram of bolts of the energy storage protection device of the energy storage photovoltaic power station provided in this application, such as Figure 5 As shown, the bolt 5 includes a threaded rod 51 and a knob 53, wherein the threaded rod 51 and the knob 53 are fixedly connected, and the threaded rod 52 can pass through the retaining ring 43 and the second guide sleeve 44, and then be screwed to the screw hole on the chassis 2, so as to further fix the restraining frame on the chassis 2. The retaining ring 43 is used to limit the sliding range of the bolt 5.

[0086] Furthermore, combined with Figure 1 and Figure 2 As shown, the position of the screw hole 25 is higher than the position of the first guide sleeve 23, so that when the bolt 5 is separated from the restraining frame 4, the sliding column 42 slides downward in the first guide sleeve 23, so that the restraining frame 4 changes from a state of being engaged with the flip cover 3 to a state of losing engagement with the flip cover 3.

[0087] The position of the screw hole 25 is higher than that of the first guide sleeve 23, so that when the bolt 5 is separated from the restraining frame 4, the slide column 42 moves downward in the first guide sleeve 23, causing the restraining frame 4 to change from a state of being engaged with the flip cover 3 to a state of losing engagement with the flip cover 3, so that the flip cover can be opened.

[0088] Furthermore, the bolt 5 also has a movable rod 52 , wherein the movable rod 52 is between the threaded rod 51 and the knob 53 , and is fixedly connected to the threaded rod 51 , that is, the bolt 5 is integrally formed with the knob 53 , the movable rod 52 and the threaded rod 51 .

[0089] The threaded rod 51 is slidably inserted into the second guide sleeve 44, the movable rod 52 is slidably penetrated through the retaining ring 43, the threaded rod 51 is threadedly installed at the lower part of the box body 21, and the movable rod 52 is fixedly connected between the threaded rod 51 and the knob 53. By screwing the knob 53, the movable rod 52 is acted on by the knob 53, and the threaded rod 51 is screwed out of the box body 21, or the threaded rod 51 is screwed back into the box body 21.

[0090] Furthermore, the outer periphery of the knob 53 of the bolt 5 is provided with anti-skid patterns, which increase the friction between the knob 53 and the finger.

[0091] During the specific implementation process, when the components are stored in the energy storage protection device, the flap 3 receives the thrust of the telescopic component 1, rotates freely around the rotating shaft 31 to open, and then the energy storage element and the like are placed in the box body 21, the flap 31 is closed, the restraining strip 41 of the restraining frame 4 is inserted into the lower end of the flap 3, and the sliding column 42 on the restraining frame 4 is inserted into the first guide sleeve 23 in the box body 21, the bolt 5 is inserted into the knob 53, the movable rod 52 and the threaded rod 51, and the threaded rod 51 is spirally connected to the screw hole 25 to complete the installation of the energy storage protection device.

[0092] When opening the energy storage protection device, that is, when the battery or other components inside the chassis 2 need to be replaced, the bolt 5 is first loosened to disengage the bolt 5 from the chassis 2, and the restraining frame 4 slides downward, so that the lower part of the flip cover 3 is freed from restraint, and the telescopic rod 1 is driven to push the flip cover 3 to swing upward and open, thereby increasing the entry and exit range of the chassis 2.
