In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0040] See also Figure 1 and Figure 2As shown, the present invention provides a power supply cabinet for an energy storage system, comprising: a cabinet mechanism 1, a base mechanism 2 and a ceiling mechanism 3, wherein the cabinet mechanism 1 is installed above the base mechanism 2, and the ceiling mechanism 3 is installed on the top of the cabinet mechanism 1; wherein the cabinet mechanism 1 comprises an outer cabinet 11 and a closed door 12 connected by hinges, side ventilation mechanisms 13 are arranged on the left and right sides of the outer cabinet 11, a top ventilation mechanism 14 is installed on the top of the outer cabinet 11, and a locking mechanism is arranged between the outer cabinet 11 and the closed door 12. The base mechanism 2 includes an annular bottom groove 21, and a plurality of lock hooks 22 are arranged on the outer edge of the bottom groove 21; the ceiling mechanism 3 includes a rainproof canopy 31 installed on the top of the outer cabinet 11 through a support frame 32, and a folded waterproof cloth 33 is connected to the bottom of the rainproof canopy 31, and a counterweight ring 34 is connected to the bottom of the waterproof cloth 33; a control mechanism 4 is arranged on the outer side of the closed door 12, a water level sensor 5 is installed on the inner side of the bottom of the bottom groove 21, and a temperature sensor 6 is arranged on the inner side wall of the outer cabinet 11;

[0041] In this embodiment, when installing the equipment, a suitable position is selected to fix the base mechanism 2 on the ground or the installation platform, and then the cabinet mechanism 1 is installed on the base mechanism 2, and the ceiling mechanism 3 is installed on the top of the cabinet mechanism 1 to play a protective role, and the energy storage system is installed in the outer cabinet 11 of the cabinet mechanism 1 for use. During use, the outer cabinet 11 and the closed door 12 are locked by the locking mechanism 15, so that the energy storage system is used in a relatively closed environment, thereby improving the protection of the energy storage equipment, and the side ventilation mechanism 13 and the top ventilation mechanism 14 can be used to circulate air between the inside of the cabinet mechanism 1 and the outside, so as to achieve the purpose of cooling the internal equipment. In addition, when the water level sensor 5 detects that water accumulates in the cabinet mechanism 1, the rainproof canopy 31 is released through the ceiling mechanism 3, and a fully surrounding structure of the cabinet mechanism 1 is formed with the ground or the installation platform to prevent excessive water accumulation from submerging the cabinet mechanism 1, and water entering the cabinet mechanism 1 damages the energy storage system, thereby achieving the purpose of protecting the equipment.

[0042] In a preferred embodiment, please refer to Figure 3 As shown, a sealing groove 110 is provided at the opening of the outer cabinet 11, a sealing strip 111 is provided on the inner side of the sealing groove 110, and a boss 120 is provided on the side where the closed door 12 contacts the outer cabinet 11;

[0043] In this embodiment, the outer cabinet 11 is closed by the closing door 12. When the closing door 12 and the outer cabinet 11 are closed, the boss 120 on the closing door 12 can just fill the sealing groove 110, so that the combination between the outer cabinet 11 and the closing door 12 is tighter and more stable. When the boss 120 is filled in the sealing groove 110, the sealing strip 111 is squeezed at the same time, so that the sealing strip 111 fills the gap between the boss 120 and the sealing groove 110, so that the outer cabinet 11 and the closing door 12 are more tightly sealed to prevent infiltration from the gap. In addition, the drip groove 112 can discharge the accumulated water in the sealing groove 110.

[0044] Next, please refer to Figures 3 to 5 As shown, the side ventilation mechanism 13 includes a side vent 130 connected to the outer cabinet 11, a side filter plate 131 is installed in the side vent 130, and the top ventilation mechanism 14 includes a top vent 140 connected to the outer cabinet 11, an exhaust fan 141 is installed in the top vent 140, and a top filter plate 142 is installed on the inner side of the top vent 140 above the exhaust fan 141, and a sloping platform 144 is provided at the upper end of the top filter plate 142, and a clamping strip 143 is rotatably provided at the top of the top vent 140;

[0045] In the above structure, the heat is dissipated to the inside of the outer cabinet 11 through the side ventilation mechanism 13 and the top ventilation mechanism 14, and the temperature sensor 6 is installed inside the outer cabinet 11 to monitor the temperature inside the outer cabinet 11 in real time, and transmit the data to the control mechanism 4 for data analysis. When the temperature inside the outer cabinet 11 is low, the natural circulation of air with the outside world can be achieved through the side vents 130 on both sides and the top vents 140, so as to achieve the heat dissipation inside the outer cabinet 11. When the temperature sensor 6 detects that the temperature inside the outer cabinet 11 is too high, the signal can be transmitted to the control mechanism 4, and the control mechanism 4 The exhaust fan 141 of the top vent 140 is controlled to be turned on, so that the air in the outer cabinet 11 is discharged through the top vent 140, and the outside air enters the outer cabinet 11 from the side vent 130, so as to realize the directional circulation of the air between the outer cabinet 11 and the outside, and accelerate the air circulation rate, so that the heat dissipation effect of the outer cabinet 11 is enhanced. After the temperature in the outer cabinet 11 drops, the exhaust fan 141 is turned off, and the exhaust fan 141 is controlled to be turned on and off in time, so as to achieve the purpose of saving. In addition, the temperature sensor 6 can be used with a sensor of the brand model MAXIM-DS18B20;

[0046] A side filter plate 131 is installed at the side vent 130, and a top filter plate 142 is installed at the top vent 140, so that the air entering the outer cabinet 11 can be filtered to prevent external dust and the like from entering and adhering to the system components, thereby affecting the performance of the components. In addition, the top filter plate 142 is installed by directly placing it on the top vent 140, and the top filter plate 142 is clamped and fixed by rotating the clamping strip 143, so that the installation method of the top filter plate 142 is simpler and the disassembly, cleaning and installation of the top filter plate 142 are convenient. A ramp-shaped boss 144 is provided at the top of the top filter plate 142, so that when the clamping strip 143 is rotated, the extrusion pressure generated by the boss 144 is greater, and the top filter plate 142 can be clamped more tightly to prevent loosening due to long-term use.

[0047] Secondly, please refer to Figure 6 As shown, the lock mechanism 15 includes a lock tongue 150 arranged on the inner side of the outer cabinet 11, a paddle 151 is connected to the outer side of the lock tongue 150, a spring 152 is installed at the bottom end of the lock tongue 150, the upper and lower sets of lock tongues 150 are connected by a connecting rod 153, a lock plate 154 is installed at the closed door 12 corresponding to the lock tongue 150, and a limit bolt 155 is installed below the lower lock tongue 150, and the limit bolt 155 is connected to the outer cabinet 11 through a threaded engagement;

[0048] In the above structure, the outer cabinet 11 and the closed door 12 are locked by the lock mechanism 15. When the closed door 12 is closed, the lock plate 154 on the closed door 12 will be inserted into the outer cabinet 11, and the lock tongue 150 will be gradually pushed down by the inclined surface at the lower front side of the lock plate 154. When the closed door 12 is fully closed, the lock plate 154 is also inserted into place, and then the elastic force of the spring 152 pushes the lock tongue 150 to move up and get stuck in the groove of the lock plate 154, so as to achieve the locked state. When the closed door 12 needs to be opened, the lock tongue 150 is driven downward by the paddle 151, so that the lock tongue 150 and the lock plate 154 are disengaged, so that the closed door 12 can be opened, and the function of the connecting rod 153 is to connect the lock tongues 150 of the upper and lower lock mechanisms 15. When one lock tongue 150 moves up, it will drive the other lock tongue 150 to move at the same time, so that the movement of the two lock tongues 150 can produce a synchronous effect.

[0049] The lock mechanism 15 in this embodiment is relatively convenient to open and close, and can be opened without using a key. In order to ensure safety in use without a lock, a limit bolt 155 is installed below a lock tongue 150 below. The limit bolt 155 supports the lock tongue 150. Without removing the limit bolt 155, the lock tongue 150 cannot move downward, which will make it impossible to release the engagement between the lock tongue 150 and the lock plate 154, making it difficult for non-staff to open the cabinet, thereby ensuring the safety of use of system components inside the cabinet mechanism 1.

[0050] In a preferred embodiment, please refer to Figure 7 A second guide rod 310 is extended downwardly from the inner side of the rainproof shed 31, a locking block 340 is installed on the inner side of the counterweight ring 34, and the locking block 340 is sleeved on the outer side of the second guide rod 310, and the counterweight ring 34 is located directly above the bottom groove 21, and a third guide rod 320 is extended toward the counterweight ring 34 from the support frame 32, a second locking hook 321 is sleeved on the third guide rod 320, and a third spring 322 is sleeved on the third guide rod 320, one end of the third spring 322 is pressed against the third guide rod 320, and the other end of the third spring 322 is pressed against the second locking hook 321, and a snap-fit ​​structure is formed between the second locking hook 321 and the locking block 340, and an electromagnet 323 is installed on the side of the support frame 32 away from the counterweight ring 34, and a magnetic connection is formed between the electromagnet 323 and the second locking hook 321;

[0051] In this embodiment, the rainproof canopy 31 is the topmost structure of the device, which can provide a shield for the device from wind and rain, and the guide rod 2 310 is mainly used to guide the counterweight ring 34 when releasing the counterweight ring 34, so that the counterweight ring 34 can fall more stably and fall into the bottom groove 21 accurately.

[0052] When the water level sensor 5 installed in the bottom groove 21 detects that water accumulates around the bottom of the outer cabinet 11, it transmits a signal to the control mechanism 4 through the wired structure. The control mechanism 4 judges the situation and uses the control mechanism 4 to control the electromagnet 323 installed on the support frame 32 to be energized to generate magnetism. Then the second lock hook 321 overcomes the elastic force of the third spring 322 and moves along the guide rod 320 toward the side of the electromagnet 323, so that the second lock hook 321 is disengaged from the locking block 340 on the counterweight ring 34. Then the counterweight ring 34 falls downward due to gravity, and drives the waterproof cloth 33 to extend downward and unfold, thereby protecting the outer cabinet 11 and preventing the water level from continuing to rise and immersing into the outer cabinet 11 to cause damage to the internal equipment.

[0053] After the counterweight ring 34 is released and falls, the power to the electromagnet 323 can be released, so that the electromagnet 323 loses its magnetism. Due to the elastic force of the spring three 322, the lock hook two 321 will move away from the electromagnet 323 and return to its original position. When the waterproof cloth 33 is not in use, the counterweight ring 34 can be lifted upward so that the locking block 340 is re-engaged with the lock hook two 321, so that the counterweight ring 34 can be released by powering on next time for easy reuse.

[0054] In a preferred embodiment, please refer to Figure 8 As shown, a sealing sheet 1 210 is installed at the inner bottom end of the bottom groove 21, a sealing sheet 211 is installed at the outer bottom end of the bottom groove 21, and an arc-shaped guide sheet 23 is installed at the top end of the bottom groove 21;

[0055] In this embodiment, the bottom groove 21 can be installed with the ground or the installation platform by burying expansion bolts on the ground or the installation platform or fastening them with ordinary bolts. During installation, the outer ground of the bottom groove 21 contacts the ground or the installation platform, and a sealing sheet 211 is provided on the bottom surface of the bottom groove 21 to fill the gap generated when the bottom groove 21 contacts the ground or the installation platform, thereby preventing water from seeping in from the gap.

[0056] The counterweight ring 34 will eventually fall into the bottom groove 21 after being released, and the function of the sealing sheet 210 is to fill the seal produced when the bottom groove 21 contacts the counterweight ring 34, thereby preventing the infiltration of accumulated water and achieving a better sealing effect.

[0057] Second, see Fig. 9 and Fig.10 As shown, the inner side of the lock hook 22 is connected with a guide rod 220, and the guide rod 220 is sleeved with a spring 221, one end of the spring 221 is pressed against the outer end of the guide rod 220, and the other end of the spring 221 is pressed against the lock hook 22, and the lower end of the lock hook 22 is slidably connected to the slide seat 222;

[0058] In this embodiment, after the counterweight ring 34 falls into the bottom groove 21, it will be fastened and fixed by the lock hook 22. When the counterweight ring 34 falls into the bottom groove 21 from above, it can fall into the bottom groove 21 more accurately through the guiding effect of the arc-shaped guide piece 23. When the counterweight ring 34 is in free fall, due to the action of the inclined surface of the lock hook 22, the lock hook 22 will be squeezed outward, so that the lock hook 22 moves outward along the guide rod 220 and the slide seat 222. When the counterweight ring 34 completely falls into the bottom groove 21, due to the action of the spring 221, the lock hook 22 moves in the opposite direction, thereby fastening to the upper end of the counterweight ring 34, and the counterweight ring 34 is firmly fixed in the bottom groove 21. The bottom groove 21, the ground and the waterproof cloth 33 protect the outer cabinet 11, thereby preventing the counterweight ring 34 from extending into the outer cabinet 11 and causing damage to the equipment when water accumulates.

[0059] The control mechanism 4 is electrically connected to the water level sensor 5 and the temperature sensor 6 as well as the exhaust fan 141 and the electromagnet 323;

[0060] In this embodiment, the device is precisely controlled by the control mechanism 4, and the signals detected by the water level sensor 5 and the temperature sensor 6 are used to determine when to release the counterweight ring 34 and when to start exhaust to dissipate heat for the device, making the use of the device more intelligent. In addition, the water level sensor 5 can be a sensor of the brand model ZTS-YW of Zhaotai Sheng, which is used to accurately sense the water level of the accumulated water.

[0061] The working principle of the present invention is as follows: when installing the equipment, a suitable position is selected to fix the base mechanism 2 on the ground or the installation platform, and then the cabinet mechanism 1 is installed on the base mechanism 2, and the ceiling mechanism 3 is installed on the top of the cabinet mechanism 1 to play a protective role, and the energy storage system is installed in the outer cabinet 11 of the cabinet mechanism 1 for use. During use, the outer cabinet 11 and the closed door 12 are locked by the locking mechanism 15, so that the energy storage system is used in a relatively closed environment, thereby improving the protection of the energy storage equipment, and the side ventilation mechanism 13 and the top ventilation mechanism 14 can be used to circulate air between the inside of the cabinet mechanism 1 and the outside world, so as to achieve the purpose of cooling the internal equipment. In addition, when the water level sensor 5 detects that water accumulates in the cabinet mechanism 1, the rainproof canopy 31 is released through the ceiling mechanism 3, and a fully surrounding structure is formed with the ground or the installation platform for the cabinet mechanism 1, so as to avoid excessive water accumulation and submerging the cabinet mechanism 1, and water entering the cabinet mechanism 1 to damage the energy storage system, thereby achieving the purpose of protecting the equipment.

[0062] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
