DETAILED DESCRIPTION

[0036] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1 to 8 As shown, this embodiment proposes a liquid-cooled energy storage device, including a body 1, movable doors 2 are rotatably connected to both sides of the front of the body 1, handles 3 are fixedly connected to the front of the two movable doors 2, a plurality of ventilation grooves are provided on the rear side of the body 1, a baffle 4 is fixedly connected to the rear side of the body 1, a plurality of energy storage batteries 5 and two liquid cooling components are respectively installed on both sides of the body 1, one side of one of the liquid cooling components is fixedly connected to an integrated over-temperature alarm 6, a connecting mechanism 7 is provided inside the body 1, and a plurality of wedge-shaped grooves are provided inside one of the movable doors 2;

[0039] The connecting mechanism 7 includes a shell 701, one side of which is fixedly connected to a side wall of the inner cavity of the body 1, a motor 702 is fixedly connected inside the shell 701, the motor 702 is fixedly connected to a threaded rod 703 via an output shaft, the outside of the threaded rod 703 is connected to a threaded block 705 via a thread, a side wall of the inner cavity of the body 1 is fixedly connected to a bottom plate 704, the threaded block 705 extends to the inside of the bottom plate 704 and is connected to the bottom plate 704 via a thread, a connecting plate 706 is fixedly connected to one side of the outer side of the threaded block 705, a round block is fixedly connected to one side of the top of the connecting plate 706, and a top rod 707 is fixedly connected to the top of the round block.

[0040] In this embodiment, the baffle 4 is located outside the multiple air-permeable grooves, the threaded rod 703 is connected to the shell 701 through a bearing, the cross-section of the connecting plate 706 is set to a U shape, one side of the connecting plate 706 is fixedly connected to the limiting block 708, and a limiting groove is provided on one side wall of the inner cavity of the body 1. The limiting block 708 extends to the inside of the limiting groove and contacts between the limiting grooves, which can facilitate the limiting block 708 to limit the connecting plate 706.

[0041] In this embodiment, a dredging mechanism 8 is provided inside the body 1, and the dredging mechanism 8 includes a sliding plate 801, the bottom of the sliding plate 801 is in contact with the top of the top rod 707, a folding rod 802 is fixedly connected to one side of the sliding plate 801, and a strip plate 803 is provided outside the sliding plate 801. The sliding plate 801 and the strip plate 803 are slidably connected to each other, which can facilitate the sliding work of the sliding plate 801 inside the strip plate 803.

[0042] In this embodiment, a strip groove is opened inside one of the movable doors 2, and the strip plate 803 is slidingly connected to the strip groove. A plurality of movable plates 804 are provided on one side of the folding rod 802, and one side of one movable plate 804 is fixedly connected to the outer end of the folding rod 802. Two springs 805 are fixedly connected to both sides of the outside of the plurality of movable plates 804, and the outer ends of the plurality of springs 805 are fixedly connected to adapter blocks 806, which can facilitate the springs 805 to drive the adapter blocks 806 to move.

[0043] During use, when the device needs to be cooled, first, the heat inside the body 1 will circulate through the ventilation grooves and the wedge-shaped grooves. During this process, the heat will be taken away by the circulating air. If the wedge-shaped grooves are blocked during long-term use, the temperature inside the body 1 will rise. After the temperature rises, the integrated over-temperature alarm 6 will receive a signal. After receiving the signal, the integrated over-temperature alarm 6 will start to sound an alarm to notify the staff to come to the scene.

[0044] When the staff arrives at the site, they turn on the motor 702. After being turned on, the motor 702 will synchronously drive the threaded rod 703 to rotate forward. During the rotation of the threaded rod 703, the threaded block 705 will move up on its surface. During the movement, the threaded block 705 will synchronously drive the connecting plate 706 to move. The movement of the connecting plate 706 will synchronously drive the top rod 707 to move upward. During this process, the connecting plate 706 will move away from the top of the bottom plate 704, and the distance between the two will become farther and farther. Then, when the top rod 707 contacts the bottom of the sliding plate 801 and continues to apply force during the upward movement, the sliding plate 801 will slide upward from the bottom of the slide groove inside the strip plate 803. During the movement, the sliding plate 801 will synchronously drive the folding rod 802 to slide. When the sliding plate 801 slides to the top of the slide groove, The strip plate 803 continues to be driven to move upward. During this process, the folding rod 802 will slide inside the strip groove of the movable door 2, and the moving plate 804 will be driven to move synchronously during the sliding process. The moving plate 804 will synchronously drive the spring 805 and the adapter block 806 to move during the movement. When the adapter block 806 gradually moves into the wedge-shaped groove, the compressed spring 805 will stretch rapidly. The spring 805 will quickly move the adapter block 806 into the wedge-shaped groove during the stretching process. The adapter block 806 will simultaneously clear the impurities inside the wedge-shaped groove during the movement, thereby achieving the dredging work inside the wedge-shaped groove, ensuring the air permeability and dredging convenience of multiple wedge-shaped grooves, and avoiding the occurrence of low efficiency during the dredging process. Afterwards, the staff can use tools to dredge the inside of the ventilation groove, and this process is relatively easy and convenient.

[0045] Example 2

[0046] like Figure 6 to Figure 10 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the outer surfaces of multiple adapter blocks 806 are all adapted to the wedge-shaped groove and in contact with the inside thereof, and the interiors of multiple movable plates 804 are movably connected with rollers 807 through rotating shafts, and the outer surfaces of the rollers 807 are in contact with the inside of the movable door 2, which can facilitate the rolling of the rollers 807.

[0047] In this embodiment, a counterweight plate 808 is fixedly connected between each of the plurality of movable plates 804 , and a support plate 809 is fixedly connected to the bottom of the inner cavity of the movable door 2 , so that the support plate 809 can support the movable plate 804 .

[0048] When the cleaning is completed, the staff needs to open the movable door 2. After the movable door 2 is opened, the bottom of the sliding plate 801 will be separated from the top of the top rod 707, and the multiple counterweight plates 808 will drive the movable plate 804 to fall downward by their own weight. During the falling process, the movable plate 804 will simultaneously drive the spring 805 and the adapter block 806 to fall. At this time, the falling force is greater than the stretching force of the spring 805, so when the adapter block 806 is guided and slid inside the wedge-shaped groove, it will drive the adapter block 806 to contract and the spring 805 to compress, and then the bottom movable plate 804 will fall until it contacts the top of the support plate 809, thereby realizing the support work of the movable plate 804 as a whole, and at the same time the wedge-shaped groove is in an open state, that is, the wedge-shaped groove and the adapter block 806 are staggered, which can achieve continuous ventilation.

[0049] Example 3

[0050] like Figure 11-12 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a discharge mechanism 9 is provided on one side of the movable door 2, and the discharge mechanism 9 includes two sockets 901, and the two sockets 901 are respectively fixedly connected to the two sides of the bottom of the inner cavity of the body 1, and a rotating rod 902 is connected between the two sockets 901 through a bearing, which can facilitate the supporting work of the rotating rod 902.

[0051] In this embodiment, a rotating plate 903 is fixedly connected to the outside of the rotating rod 902, the bottom of the rotating plate 903 contacts the bottom of the inner cavity of the body 1, and a base 904 is fixedly connected to one side of the top of the rotating plate 903, which can facilitate the fixed connection of the base 904.

[0052] In this embodiment, the inside of the base 904 is connected to a movable rod 905 via a bearing, and the outside of the movable rod 905 is fixedly connected to a connecting rope 906, so that the connecting rope 906 can be fixed.

[0053] In this embodiment, one end of the connecting rope 906 is fixedly connected to one side of one of the movable doors 2, and the connecting rope 906 is in a relaxed and unstretched state, which can facilitate the movable door 2 to drive the connecting rope 906 to be pulled.

[0054] After the adapter block 806 has completed the ventilation and reset work inside the wedge-shaped groove, the staff needs to adjust the motor 702 to the reverse state. The threaded rod 703 will synchronously drive the threaded block 705 to move downward during the reversal process, and then the connecting plate 706 and the top rod 707 will sink to the initial position. When the staff is in the process of closing the movable door 2, the movable door 2 will synchronously drive the sunken movable plate 804, the strip plate 803, the folding rod 802 and the sliding plate 801 to contact the top of the top rod 707, so it is convenient to separate and cooperate with each other, and will not affect the actual use. Because the structure is in a side-by-side state, it will not cause the situation of blocking the release of heat in the actual heat dissipation process. At the same time, it also ensures a larger operating space inside the body 1, saving space resources.

[0055] When the impurities are cleaned and unblocked, some of the impurities will fall on the outside of the body 1, and the other part will fall on the top of the rotating plate 903. If the staff will simultaneously drive the connecting rope 906 to pull when opening the movable door 2, the connecting rope 906 will simultaneously drive the movable rod 905 and the base 904 to pull during the pulling process, and the base 904 will simultaneously drive the rotating plate 903 to rotate and tilt during the pulling process. At this time, the impurities will be automatically discharged, ensuring the convenience of the device when used.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
