Description

Technical Field

[0001] The present invention relates to a switch cabinet, and more particularly to an anti-collision switch cabinet. Background Art

[0002] A switchgear is an electrical device. The external line of the switchgear first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Its main function is to open and close, control and protect during the process of power generation, transmission, distribution and power conversion in the power system.

[0003] Switchgear is primarily used in a variety of applications, including power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mining enterprises, residential communities, and high-rise buildings. Due to the specific nature of these scenarios, some switchgear must be installed outdoors. These are particularly vulnerable to impacts from vehicles, falling rocks, and other objects. However, existing switchgear relies solely on its external casing for collision protection, making it susceptible to damage to the electrical equipment within. This necessitates further optimization of switchgear to enhance its collision protection capabilities.

[0004] And because of the different impact points, the stress conditions inside the cabinet will also change, so the anti-collision structure needs to be optimized in a targeted manner. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide an anti-collision switch cabinet, which can form different protective operations according to different impact points, so that the protective operations are effectively targeted.

[0006] To achieve the above object, the present invention provides the following technical solutions: an anti-collision switch cabinet, comprising a semi-cylindrical cabinet, a semi-cylindrical door, a mounting cabinet body, and a controller; The installation cabinet is arranged in a semi-cylindrical cabinet, and a protective cavity is formed between the installation cabinet and the semi-cylindrical cabinet; The semi-cylindrical cabinet and the semi-cylindrical door are both provided with interlayer cavities, and each interlayer cavity is provided with three sets of protective members along its height direction, corresponding to the lower end area, the middle end area and the upper end area of ​​the interlayer cavity respectively; Each group of protective elements includes a first protective airbag and a second protective airbag; The installation cabinet is provided with an inflatable protection device, and the inflatable protection device is connected to the first protection airbag and the second protection airbag; The inner sides of the semi-cylindrical cabinet and the semi-cylindrical door are provided with sensing components that cooperate with the first protective airbag and the second protective airbag, and the sensing components include a first sensing component located in the lower end area, a second sensing component located in the middle end area, and a third sensing component located in the upper end area; The protective cavity is provided with four sets of lifting support devices along its circumference.

[0007] In summary, the present invention has the following beneficial effects: it has multiple shock-absorbing and protective effects: 1. By arranging 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, thereby playing a buffering and shock-absorbing role; 2. When the corresponding protective airbag is squeezed by a collision, in order to prevent the airbag from being squeezed and ruptured, the volume of the squeezed airbag becomes smaller and the internal air pressure increases during the squeezing process, which will be transmitted to the inflatable protective device.

[0008] 3. When a collision occurs at the corresponding position, the collision situation is judged based on the changes in the airbag at the corresponding position, and the severity of the collision is judged based on the changes in the air pressure in the airbag, so as to perform support and auxiliary operations.

DETAILED DESCRIPTION

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0012] Reference Figures 1 to 5 As shown, in order to achieve the above purpose, the present invention provides the following technical solutions: an anti-collision switch cabinet, comprising a semi-cylindrical cabinet 1, a semi-cylindrical door 2, an installation cabinet 3 and a controller 4; The installation cabinet 3 is arranged in the semi-cylindrical cabinet 1, and a protective cavity 5 is formed between the installation cabinet 3 and the semi-cylindrical cabinet 1; Both the semi-cylindrical cabinet 1 and the semi-cylindrical door 2 are provided with interlayer cavities 6. Three sets of protective members 7 are provided in each interlayer cavity 6 along its height direction, corresponding to the lower end area, the middle end area and the upper end area of ​​the interlayer cavity 6 respectively. Each set of protective elements 7 includes a first protective airbag 71 and a second protective airbag 72 ; six sets of protective elements 7 each include six first protective airbags 71 and six second protective airbags 72 .

[0013] An inflatable protection device 8 is provided on the installation cabinet 3, and the inflatable protection device 8 is connected to the first protective airbag 71 and the second protective airbag 72; The inner sides of the semi-cylindrical cabinet 1 and the semi-cylindrical door 2 are provided with a sensing component 9 that cooperates with the first protective airbag 71 and the second protective airbag 72. The sensing component 9 includes a first sensing component 91 located in the lower end area, a second sensing component 92 located in the middle end area, and a third sensing component 93 located in the upper end area. The protective cavity 5 is provided with four groups 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, and the controller 4 controls the corresponding lifting support device 51 to perform lifting operations according to the sensing signals of the first sensing component 91, the second sensing component 92 and the third sensing component 93.

[0014] The design of the present invention has multiple shock-absorbing and protective effects: 1. By arranging a protective airbag in the interlayer 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 shell of the semi-cylindrical cabinet 1 and the semi-cylindrical door 2 deforms, thereby squeezing the protective airbag, thereby playing a buffering and shock-absorbing role; 2. When the corresponding protective airbag is squeezed by a collision, in order to prevent the airbag from 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 be transmitted to the inflatable protection device 8.

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

[0016] The first sensing component 91, the second sensing component 92, and the third sensing component 93 each include a mounting base 94 and a sensor 95. An installation cavity 96 is formed between the mounting base 94 and the semi-cylindrical cabinet 1 or the semi-cylindrical door 2. The sensor 95 is installed in the installation cavity 96, and the installation cavity 96 is communicated with the corresponding sandwich cavity 6.

[0017] The mounting base 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, since the degree of squeezing is not high, the sensor 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.

[0018] 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 hinged with the hinge plate.

[0019] 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, thus forming a support. [[ID=k]]

[0020] Multiple ventilation channels 11 are arranged 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 cavities 83 are arranged in the inflation seat 81, and each inflation cavity 83 is respectively communicated with the adjacent first protection airbag 71 or second protection 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; A one - way air nozzle is arranged in the ventilation channel 11.

[0021] The one - way air nozzle is made of rubber and is arranged in the ventilation channel 11 to block the injection of gas from the protection airbag into the inflation column. When the semi - cylindrical cabinet 1 or the semi - cylindrical door 2 is squeezed, the pressure in the protection airbag increases, thus breaking through the one - way air nozzle and making the gas injected into the corresponding inflation cavity 83. e

[0022] In addition, the one - way air nozzle can also be replaced by a one - way air valve.

[0023] An operation port 84 is arranged at the upper end of the inflation seat 81. A floating block 85 is slidably connected in the operation port 84. A buckling groove 86 is formed between the upper end of the floating block 85 and the opening of the operation port 84; Preferably, a guiding groove is arranged between the four buckling grooves 86, which can ensure the smoothness of the rotation process of the buckling block 823.

[0024] The rotating device 82 includes a rotating base 821, a rotating disk 822, and a buckle block 823. The rotating base 821 is fixedly connected to the inflatable seat 81, and the rotating disk 822 is rotatably connected to the rotating base 821. An opening is opened on one side of the installation cabinet 3. The buckle block 823 is hinged to the side of the rotating disk 822 near the opening and is used to buckle with the buckle groove 86. An energy storage component 87 is provided between the rotating base 821 and the rotating disk 822 .

[0025] For example, when a collision occurs, the first protective airbag 71 and the second protective airbag 72 on the semi-cylindrical door 2 are squeezed. 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, so that the air pressure in the inflation chamber 83 increases, and the floating block 85 moves upward, pushing the buckle block 823 out of the buckle groove 86. Under the action of the energy storage component 87, the rotating disk 822 drives the installation cabinet 3 to rotate until the buckle block 823 is buckled into the normal buckle groove 86 again, restoring the function of limiting the rotation of the rotating disk 822. At this time, the opening of the installation cabinet 3 is facing away from the collision area, and the cabinet 3 is installed to protect the electrical appliances in the installation cabinet 3.

[0026] When the collision area itself faces away from the opening of the installation cabinet 3, the air pressure in the corresponding inflation cavity 83 increases, and the floating block 85 moves upward, but the buckle block 823 does not correspond to it, so the installation cabinet 3 will not rotate.

[0027] The energy storage component 87 includes a rotating block and a coil spring, which is connected to the rotating disk 822 and is arranged in the rotating base 821. The design of this structure can achieve the effect of energy storage by initially rotating the rotating disk 822 so that the rotating block squeezes the coil spring.

[0028] Further preferably, a door that is not often opened is provided on the side of the semi-cylindrical cabinet away from the semi-cylindrical door 2, which is used to install the cabinet body 3 so that it can rotate 180° to face the door at the rear when the semi-cylindrical door 2 is deformed by a collision.

[0029] Since four groups of inflation chambers 83 are provided, the mounting cabinet 3 can be rotated 90°, 180°, and 270°.

[0030] The processing method of the controller 4 includes: A1. When the first sensing component 91 in the lower end area is triggered, the controller 4 controls the lifting rod on the far side to start. After the lower end area is hit and sunken, the cabinet on the far side will bend. At this time, the lifting rod is used to support it, thereby strengthening the internal strength.

[0031] A2. When the third sensing component 93 in the upper end area is triggered, the controller 4 controls the lifting rod on the adjacent side to start; when a collision occurs in the upper end area, the switch cabinet will tilt along the collision direction. At this time, the lifting rod on the adjacent side corresponding to the collision side supports it, thereby strengthening the internal strength.

[0032] A3: When the second sensing element 92 in the middle region is triggered, the controller 4 activates all the lifting rods. When a collision occurs in the middle region, the lower region folds upward and the upper region folds downward. At this time, the lifting rods on all sides provide support, thereby strengthening the internal strength.

[0033] Furthermore, if the collision area is too large, for example, when large areas of depression appear in both the lower end area and the middle end area, the controller 4 controls the corresponding lifting rod to provide support according to the corresponding trigger information.

[0034] The processing method of the controller 4 can face collisions at different positions and perform corresponding supporting operations.

[0035] like Figure 1 As shown, it also includes a mounting base, and the semi-cylindrical cabinet 1 can be detachably mounted on the mounting base. The semi-cylindrical cabinet includes a mounting chassis at the lower end; the mounting base is embedded, and a groove of a certain depth is dug in the ground, and 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.

[0036] A plurality of elastic switches 12 are arranged on the mounting chassis and are arranged equidistantly along the circumference of the mounting chassis; The elastic switch 12 is electrically connected to the controller 4. The elastic switch 12 is a button type. When the semi-cylindrical cabinet 1 is installed on the mounting base, the elastic switch 12 will be pressed. When the semi-cylindrical cabinet 1 is bumped and lifted, the elastic switch 12 at the corresponding position contacts the limit, thereby triggering the induction.

[0037] There are four sets of elastic switches 12. When the semi-cylindrical cabinet 1 is lifted, the processing method of the controller 4 also includes: 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 will cause the switch cabinet to separate from the ground when the collision force is too large. At this time, the lifting rod on the adjacent side can be activated through the action of the lifting rod, thereby forming a support to keep the equipment stable.

[0038] B2, when multiple elastic switches 12 are triggered, the controller 4 controls all the lifting rods to close.

[0039] When multiple elastic switches 12 are triggered, it means that the switch cabinet may fall over. At this time, the controller 4 receives an instruction to retract all the lifting rods to avoid more serious damage.

[0040] The lifting rod can be a cylinder or a motor assembly.

[0041] The semi-cylindrical door 2 includes three groups of cabinet doors, and three groups of protective members 7 are respectively arranged in the three groups of cabinet doors. The design of this structure can reduce the interference between the three groups of cabinet doors during collision.

[0042] The adjacent side and the distal side mentioned above are explained. When the first surface of the semi-cylindrical door 2 collides, the side close to the collision surface is the adjacent side mentioned above. On the contrary, the distal side is the position away from the first surface.

[0043] 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 based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
