Description

Technical Field

[0001] This invention relates to a switch cabinet, and more specifically, to an anti-collision switch cabinet. Background Technology

[0002] A switchgear is an electrical device. External lines first enter the main control switch inside the switchgear, and then enter the branch control switches. Each branch is set up according to its needs. Its main function is to perform opening, closing, control and protection during the power generation, transmission, distribution and energy conversion process of the power system.

[0003] Switchgear is mainly used in various settings such as power plants, substations, petrochemical plants, metallurgical steel rolling mills, light industry and textiles, factories and mines, residential communities, and high-rise buildings. Due to the specific characteristics of certain scenarios, some switchgear needs to be installed outdoors, especially those installed on roadsides or hillsides, which are at risk of being hit by vehicles, falling rocks, or other objects. However, existing switchgear relies solely on its external casing for impact protection, making it susceptible to damage to the internal electrical equipment after an external impact. Therefore, further optimization of the switchgear is needed to improve its impact resistance.

[0004] Furthermore, the stress conditions inside the cabinet will vary depending on the point of impact, thus requiring targeted optimization of the anti-collision structure. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an anti-collision switch cabinet that can form different protective operations according to different impact points, so that the protective operations are effectively targeted.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-collision switch cabinet, comprising a semi-cylindrical cabinet, a semi-cylindrical door, a mounting cabinet, and a controller;

[0007] The mounting cabinet is housed inside a semi-cylindrical cabinet, and a protective cavity is formed between the mounting cabinet and the semi-cylindrical cabinet.

[0008] Both the semi-cylindrical cabinet and the semi-cylindrical door are provided with a mezzanine cavity. Each mezzanine cavity is provided with three sets of protective components along its height direction, which correspond to the lower, middle and upper regions of the mezzanine cavity, respectively.

[0009] Each set of protective components includes a first protective airbag and a second protective airbag;

[0010] The mounting cabinet is equipped with an inflation protection device, which is connected to the first protective airbag and the second protective airbag.

[0011] The inner side of the semi-cylindrical cabinet and the semi-cylindrical door is provided with sensing components that work in conjunction with the first and second protective airbags. The sensing components include a first sensing component located in the lower region, a second sensing component located in the middle region, and a third sensing component located in the upper region.

[0012] The protective cavity is equipped with four sets of lifting support devices along its circumference.

[0013] In summary, the present invention has the following beneficial effects: it has multiple shock absorption and protection functions: 1. By setting a protective airbag in the interlayer cavity of the semi-cylindrical cabinet and the semi-cylindrical door, when an object hits the semi-cylindrical cabinet and / or the semi-cylindrical door, the metal shell of the semi-cylindrical cabinet and the semi-cylindrical door deforms, thereby squeezing the protective airbag, thus playing a buffering and shock absorption role.

[0014] 2. When the corresponding protective airbag is impacted and squeezed, in order to prevent the airbag from rupturing, the volume of the squeezed airbag decreases and the internal air pressure increases during the squeezing process, which will be transmitted to the inflation protection device.

[0015] 3. When a collision occurs at the corresponding location, the collision situation is judged based on the changes in the airbag at the corresponding location, and the severity of the collision is judged based on the changes in the air pressure inside the airbag, so as to perform support and assistance operations.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1 to 5 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: an anti-collision switch cabinet, comprising a semi-cylindrical cabinet 1, a semi-cylindrical door 2, a mounting cabinet 3, and a controller 4;

[0024] The mounting cabinet 3 is located inside the semi-cylindrical cabinet 1, and a protective cavity 5 is formed between the mounting cabinet 3 and the semi-cylindrical cabinet 1.

[0025] Both the semi-cylindrical cabinet 1 and the semi-cylindrical door 2 are provided with a mezzanine cavity 6. Each mezzanine cavity 6 is provided with three sets of protective components 7 along its height direction, which correspond to the lower, middle and upper areas of the mezzanine cavity 6 respectively.

[0026] Each set of protective components 7 includes a first protective airbag 71 and a second protective airbag 72; the six sets of protective components 7 each have six first protective airbags 71 and six second protective airbags 72.

[0027] The mounting cabinet 3 is equipped with an inflation protection device 8, which is connected to the first protective airbag 71 and the second protective airbag 72.

[0028] The inner sides of the semi-cylindrical cabinet 1 and the semi-cylindrical door 2 are provided with sensing components 9 that work in conjunction with the first protective airbag 71 and the second protective airbag 72. The sensing components 9 include a first sensing component 91 located in the lower region, a second sensing component 92 located in the middle region, and a third sensing component 93 located in the upper region.

[0029] The protective cavity 5 is provided with four sets of lifting support devices 51 along its circumference. The controller 4 is electrically connected to the first sensing component 91, the second sensing component 92, the third sensing component 93 and the lifting support device 51 respectively. The controller 4 controls the corresponding lifting support device 51 to perform lifting operation according to the sensing signals of the first sensing component 91, the second sensing component 92 and the third sensing component 93.

[0030] The design of the present invention has multiple shock-absorbing and protective functions: 1. By arranging protective airbags in the sandwich cavity 6 of the semi-cylindrical cabinet 1 and the semi-cylindrical door 2, when an object hits the semi-cylindrical cabinet 1 and / or the semi-cylindrical door 2, the metal outer shells of the semi-cylindrical cabinet 1 and the semi-cylindrical door 2 deform, thereby squeezing the protective airbags, thus playing a role in buffering and shock absorption;

[0031] 2. When the corresponding protective airbag is collided and squeezed, in order to avoid the airbag being squeezed and ruptured, during the squeezing process, the volume of the squeezed airbag becomes smaller and the internal air pressure becomes larger, which will then be transmitted to the inflation protection device 8.

[0032] 3. When a collision occurs at the corresponding position, based on the changes in the airbag at the corresponding position, the collision situation is judged, and based on the air pressure change in the airbag, the severity of the collision is judged to perform support and auxiliary operations.

[0033] The first induction component 91, the second induction component 92, and the third induction component 93 all include a mounting seat 94 and an inductor 95. An installation cavity 96 is formed between the mounting seat 94 and the semi-cylindrical cabinet 1 or the semi-cylindrical door 2. The inductor 95 is installed in the installation cavity 96, and the installation cavity 96 is communicated with the corresponding sandwich cavity 6.

[0034] The mounting seat 94 is arranged in a "C" - shaped structure to form the corresponding installation cavity 96. With this structural design, when there is a slight collision, even if the airbag is squeezed, but due to the low degree of squeezing, the inductor 95 in the installation cavity 96 will not be triggered, thus avoiding unnecessary triggering operations. Only when the collision reaches a certain degree will the corresponding support operation be triggered.

[0035] Each lifting support device 51 includes a lifting seat, a lifting rod, and a hinge plate. The lifting seat is fixedly installed beside the installation cabinet body 3. One end of the lifting rod is fixedly connected to the lifting seat, and the other end is hingedly provided with a hinge plate.

[0036] With this structural design, the lifting rod drives the hinge plate to abut against the semi-cylindrical cabinet 1 or the semi-cylindrical door 2 to form a support.

[0037] Multiple groups of ventilation channels 11 are provided between the installation cabinet body 3 and the semi-cylindrical cabinet 1 and the semi-cylindrical door 2 respectively. The inflation protection device 8 includes an inflation seat 81 and a rotating device 82. Four inflation chambers 83 are arranged in the inflation seat 81, and each inflation chamber 83 is respectively communicated with the adjacent first protective airbag 71 or second protective airbag 72. The installation cabinet body 3 is rotationally connected to the inflation seat 81 through the rotating device 82, and the inflation seat 81 is fixedly connected inside the semi-cylindrical cabinet 1;

[0038] One-way air nozzles are arranged in the ventilation channels 11.

[0039] The one-way air nozzle is made of rubber and is located in the ventilation channel 11. It is used to prevent the protective airbag from injecting gas into the inflation column. When the semi-cylindrical cabinet 1 or the semi-cylindrical door 2 is squeezed, the pressure inside the protective airbag increases, thereby breaking through the one-way air nozzle and allowing gas to be injected into the corresponding inflation chamber 83.

[0040] In addition, a one-way air nozzle can be replaced by a one-way air valve.

[0041] An operating port 84 is provided at the upper end of the inflatable base 81. A floating block 85 is slidably connected inside the operating port 84. A snap-fit ​​groove 86 is formed between the upper end of the floating block 85 and the opening of the operating port 84.

[0042] A guide groove is provided between the four preferred fastening slots 86 to ensure the smooth rotation of the fastening block 823.

[0043] The rotating device 82 includes a rotating base 821, a rotating disk 822, and a fastening block 823. The rotating base 821 is fixedly connected to the inflatable base 81, and the rotating disk 822 is rotatably connected to the rotating base 821. An opening is provided on one side of the mounting cabinet 3. The fastening block 823 is hinged to the side of the rotating disk 822 near the opening and is used to fasten with the fastening groove 86.

[0044] An energy storage component 87 is provided between the rotating base 821 and the rotating disk 822.

[0045] For example, when a collision occurs, the first protective airbag 71 and the second protective airbag 72 on the semi-cylindrical door 2 are compressed. At this time, the gas in the first protective airbag 71 and the second protective airbag 72 enters the corresponding inflation chamber 83 through the ventilation channel 11, which increases the air pressure in the inflation chamber 83. The floating block 85 moves upward and pushes the fastening block 823 out of the fastening groove 86. Under the action of the energy storage component 87, the rotating disk 822 drives the installation cabinet 3 to rotate until the fastening block 823 is re-fastened into the normal fastening groove 86, restoring the function of limiting the rotation of the rotating disk 822. At this time, the opening of the installation cabinet 3 faces away from the collision area, and the cabinet of the installation cabinet 3 plays the role of protecting the electrical appliances inside the installation cabinet 3.

[0046] When the collision area is facing away from the opening of the mounting cabinet 3, the air pressure in the corresponding inflation chamber 83 increases, and the floating block 85 moves upward. However, the fastening block 823 does not correspond to it, so the mounting cabinet 3 will not rotate.

[0047] The energy storage component 87 includes a rotating block and a coil spring. The rotating block is connected to the rotating disk 822, and the coil spring is disposed within the rotating base 821. This structure is designed so that by initially rotating the rotating disk 822, the rotating block compresses the coil spring, thereby achieving the effect of energy storage.

[0048] In a further preferred embodiment, the semi-cylindrical cabinet has a door that is not frequently opened on the side away from the semi-cylindrical door 2, so that when the semi-cylindrical door 2 is deformed by a collision, the cabinet body 3 can be rotated 180° to face the door behind it.

[0049] Because the air chamber 83 is equipped with 4 sets, the mounting cabinet 3 can rotate 90°, 180°, and 270°.

[0050] The processing method of controller 4 includes: A1, when the first sensing component 91 in the lower area is triggered, controller 4 controls the lifting rod on the far side to start. When the lower area is dented by a collision, the cabinet on the far side will bend. At this time, the lifting rod will provide support for it, thereby strengthening the internal strength.

[0051] A2, when the third sensing component 93 in the upper region is triggered, the controller 4 controls the lifting rod on the adjacent side to start; when a collision occurs in the upper region, the switch cabinet will tilt along the collision direction, and at this time the lifting rod on the adjacent side corresponding to the collision side will support it, thereby strengthening the internal strength.

[0052] A3, when the second sensing component 92 in the middle area is triggered, the controller 4 controls all the lifting rods to start. When a collision occurs in the middle area, the lower area will bend upwards and the upper area will bend downwards. At this time, the lifting rods provide support for them, thereby strengthening the internal strength.

[0053] Furthermore, if the collision area is too large, for example, if large areas of dents appear in both the lower and middle areas, the controller 4 will control the corresponding lifting rod to provide support based on the corresponding trigger information.

[0054] The controller 4's processing method can respond to collisions at different locations and provide corresponding support operations.

[0055] like Figure 1 As shown, it also includes a mounting base. The semi-cylindrical cabinet 1 can be detachably installed on the mounting base. The semi-cylindrical cabinet includes a mounting base located at the lower end. The mounting base is embedded. First, a groove of a certain depth is dug in the ground, then the mounting base is installed inside, and then the semi-cylindrical cabinet 1 is installed on the mounting base, so that the semi-cylindrical cabinet 1 is installed stably.

[0056] Multiple sets of flexible switches 12 are installed on the mounting chassis and are arranged at equal intervals along the circumference of the mounting chassis.

[0057] The flexible switch 12 is electrically connected to the controller 4. The flexible switch 12 is a push-button type. When the semi-cylindrical cabinet 1 is installed on the mounting base, the flexible switch 12 will be blocked. When the semi-cylindrical cabinet 1 is knocked up, the flexible switch 12 at the corresponding position will contact the limit, thereby triggering the sensing.

[0058] The flexible switch 12 is provided with four sets. When the semi-cylindrical cabinet 1 is lifted, the controller 4 also includes the following processing methods:

[0059] B1, when only one elastic switch 12 is triggered, the controller 4 controls the lifting rod on the adjacent side to start; the design of this structure means that when the collision force is too large, the switch cabinet will separate from the ground. At this time, the lifting rod can start the lifting rod on the adjacent side to form support and keep the equipment stable.

[0060] B2, when multiple elastic switches 12 are triggered, controller 4 controls all lifting rods to close.

[0061] When multiple flexible switches 12 are triggered, it means that the switch cabinet may tip over. At this time, the controller 4 receives an instruction to retract all the lifting rods to avoid more serious damage.

[0062] The lifting rod can be a cylinder or a motor assembly.

[0063] The semi-cylindrical door 2 includes three sets of cabinet doors, with three sets of protective components 7 respectively installed inside the three sets of cabinet doors. This structural design can reduce interference between the three sets of cabinet doors during a collision.

[0064] To explain the adjacent side and the far side mentioned above, when the first surface of the semi-cylindrical door 2 collides, the side closer to the colliding surface is the adjacent side, and conversely, the far side is the position away from the first surface.

[0065] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
