Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage cabinets, and relates to an energy storage cabinet with a cabinet door opening and closing angle limiting device. Background Art

[0002] Energy storage cabinets are a type of equipment specially designed to store electrical energy. They have a wide range of application scenarios and play an important role in power systems, renewable energy utilization, home backup power supplies, and specific industry applications. Energy storage cabinets are of great significance to improving energy utilization efficiency, promoting the popularization of renewable energy, and enhancing the flexibility and reliability of power systems through their high-efficiency energy storage and release capabilities. Existing energy storage cabinet doors all use internal hinges, which have a certain opening and closing angle. There are three states for energy storage cabinet doors. The first is the closed state. The second is the open state but not fixed, and the third is the open state and fixed at a certain angle. In the second state, the cabinet door needs to limit the maximum opening angle to avoid physical collision between the cabinet door and the hinge / cabinet due to excessive opening and closing. In the third state, the cabinet door needs to be fixed at a specific angle, such as when the cabinet is being debugged or other maintenance work is being performed. Therefore, the existing energy storage cabinet door limit device uses a finished "limiting strut" or a self-made enhanced "limiting strut". The characteristics of the limiting strut are: it has a self-locking function when opened and closed to a specific angle, and it needs to be manually unlocked before it can be closed.

[0003] However, the door size of the energy storage cabinet is usually higher than 2 meters and wider than 1 meter, and the weight of the door alone can reach 70-200KG. Under the action of the lever, the existing limit struts are easily damaged due to insufficient strength. In addition, even if there are energy storage cabinets that use large-sized and high-strength "limit struts", they only increase the strength on the basis of conventional products and can withstand greater door tension. In actual applications, when the limit strut triggers the self-locking function, people often mistakenly think that it is stuck somewhere, and force the door to close, causing the limit strut to deform, get stuck, and then be damaged.

[0004] Therefore, a high-strength, non-destructive opening and closing limit device is needed to solve the above technical problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0026] like Figures 1 to 7 As shown, an energy storage cabinet with a cabinet door opening and closing angle limiting device comprises: an energy storage cabinet 1, a cabinet door 2, the cabinet door 2 is rotatably connected to the door frame of the energy storage cabinet 1 along a vertical rotation axis, a sliding strut 3 is provided on the upper part of the cabinet door 2, and a limiting strut 4 is provided on the lower part of the cabinet door 2; the sliding strut 3 and the limiting strut 4 are arranged on the upper and lower sides of the cabinet door respectively, the sliding strut 3 on the upper side regulates the sliding track of the cabinet door 2, and the limiting strut 4 on the lower side limits the opening and closing angle of the cabinet door 2 according to demand, and the sliding and limiting are separated. When the limiting is not needed, only the sliding strut 3 works, thereby reducing the use frequency of the limiting strut 4 and the occurrence of misoperation, thereby reducing the damage probability of the limiting strut 4;

[0027] The slide groove 31 of the sliding support rod 3 is fixedly connected to the cabinet door 2, and a slider 32 slides in the slide groove 31. One end of the slide rod 33 of the sliding support rod 3 is rotatably connected to the slider 32, and the other end of the slide rod 33 is rotatably connected to the energy storage cabinet 1. The slide groove 31 and the slide rod 33 are both horizontally arranged;

[0028] The limit block 401 of the limit support rod 4 is fixedly connected to the cabinet door 2, and at least one external limit hole 402 is provided on the limit block 401. The two ends of the limit rod 403 of the limit support rod 4 are bent and provided with limit pins 404. An internal limit hole 405 is provided in the energy storage cabinet 1. The limit pins 404 at both ends of the limit rod 403 can be respectively inserted into the external limit hole 402 and the internal limit hole 405.

[0029] Furthermore, the limiting rod 403 is divided into three sections along the length direction, the two end sections of the limiting rod 403 are rigid straight rods, the middle section of the limiting rod 403 is a spiral spring section 406, the rotation axis direction of the spring section 406 is the same as the length direction of the limiting rod 403, the two ends of the spring section 406 are respectively fixedly connected to the rigid straight rods at both ends of the limiting rod 403, the spring section 406 is provided with a pressure sensor 407, the two pressure detection ends of the pressure sensor 407 are respectively arranged at the two ends of the spring section 406, the pressure sensor 407 is electrically connected to a buzzer 408 and a power supply 409, and the buzzer 408 emits a buzzer alarm sound when the pressure sensor 407 detects that the spring section 406 is stretched and / or compressed; by arranging the spring section 406 in the middle section of the limiting support rod 4, and in the spring section 406 A pressure sensor 407 is provided so that when the cabinet door 2 is limited and the cabinet door switch pressure is too large, a buzzer 408 generates a sound alarm prompt, thereby preventing personnel from operating incorrectly and causing damage to the limit support rod 4, the cabinet door 2 or the energy storage cabinet 1; the pressure sensor 407 can be replaced by a tension sensor. When the cabinet door 2 is opened and closed with a large tension or pressure, the spring segment 406 is compressed or stretched and produces elastic reciprocating motion, which can activate the pressure sensor 407 or the tension sensor, and the sensor activation threshold can be set according to the elastic deformation coefficient of the spring segment 406 and the weight of the cabinet door 2 to prevent the sensor from giving a false alarm due to a slight touch on the cabinet door 2; the buzzer 408 can be provided on the cabinet door 2 or in the energy storage cabinet 1, and powered by the power supply in the cabinet. The layout position is flexible and changeable, and it is suitable for energy storage equipment of different models in different environments.

[0030] Furthermore, the power supply 409 is a battery, and a warning light 410 is provided on the buzzer 408, and the warning light 410 is linked with the buzzer 408, and the pressure sensor 407, the buzzer 408, the power supply 409, and the warning light 410 are arranged in the inner circle cavity of the spring segment 406; the pressure sensor 407, the buzzer 408, the power supply 409, and the warning light 410 are centrally arranged in the spring segment 406, and powered by a battery, thereby avoiding the circuit routing of the energy storage cabinet 1 to supply power to the limit support rod 4, so that the installation and use are simpler and more convenient, and can meet the application environment where the energy storage cabinet 1 cannot supply power to the outside. In addition, the added warning light 410 can flash an alarm at the same time as the buzzer 408 alarms, prompting the operator of the alarm position, so that the operator can realize that the cabinet door 2 is pulled or compressed when the limit support rod 4 is working, and thus make corrections.

[0031] Furthermore, the limit rod 403 is divided into three sections along the length direction, the two end sections of the limit rod 403 are rigid straight rods, the middle section of the limit rod 403 is a pressure sensor 407, and the two pressure detection ends of the pressure sensor 407 are respectively fixedly connected to the ends of the limit rod 403 on their respective corresponding sides; the two ends of the pressure sensor 407 are directly connected to the rigid limit rods 403 on both sides, and the pressure or tension of the limit rod 403 on the cabinet door 2 side is transmitted to the pin hole connection of the limit rod 403 on the energy storage cabinet 1 side through the pressure sensor 407; this scheme eliminates the spring section 406, so that the limit rod 403 has fewer components and is simpler, but the defect of this scheme is that the pressure sensor 407 directly bears the tension or pressure of the cabinet door 2, which has a certain impact on the service life of the pressure sensor 407.

[0032] Furthermore, a plurality of outer limiting holes 402 are provided at equal intervals on the limiting block 401; the plurality of limiting holes 402 facilitates setting different opening angles of the cabinet door 2 as required.

[0033] Furthermore, a lifting ring 5 is provided on the top of the energy storage cabinet 1, a base frame 6 is provided on the bottom of the energy storage cabinet 1, and forklift fork holes 7 are reserved on the sides of the base frame 6; the forklift fork holes 7 facilitate forklifts to carry the energy storage cabinet 1, and the base frame 6 facilitates the installation and fixation of the energy storage cabinet 1.
