Description
Technical Field

[0002] A distribution cabinet is a device used for power distribution in power systems. It is responsible for converting high or medium voltage current into low voltage current suitable for users, and is protected, controlled and monitored through various electrical components (such as circuit breakers, contactors, fuses, switches, etc.). It is widely used in power distribution systems in industrial, commercial and residential buildings, and is an important part of electrical equipment management and power transmission.
[0003] During the operation of the distribution cabinet, it may be exposed to earthquakes, mechanical vibrations or impacts during transportation, which may cause the components in the distribution cabinet to loosen or be damaged, affecting the normal operation of the power system and may even cause serious consequences such as power outages and equipment burning. Therefore, during the manufacturing process of the distribution cabinet, it is necessary to have good shockproof performance to ensure its stable operation and reliability of power supply under vibration or impact.

[0014] Compared with the existing technology, the advantages of this shockproof distribution cabinet are: 1. The present invention sets a deviation correction mechanism. When the distribution cabinet is not vibrated during use, the distance between the bottom of the cabinet and the base is monitored in real time through multiple distance sensors. After a long period of vibration, impact or use, when the buffer spring becomes metal fatigued and its elastic coefficient becomes different, it will cause the shockproof distribution cabinet to tilt. At this time, the hydraulic oil inside it is transported to the deviation correction groove on the tilted side through an infusion tube, so that the piston plate in the deviation correction groove is displaced upward, and then the reference surface of the bottom of the first buffer spring at this position is displaced upward, increasing the compression degree of the first buffer spring on the tilted side, so that the elastic supporting force of the first buffer spring is restored to the same as that at other positions, thereby driving the cabinet to return to a horizontal state. When the first buffer spring becomes metal fatigued, the height of its bottom supporting position can be adjusted to avoid tilting or instability of the shockproof distribution cabinet.
[0015] 2. The present invention sets a cleaning mechanism. When the piston plate moves to adjust the first buffer spring, the first screw drives the reciprocating screw to rotate through the driving gear and the transmission gear, and drives the fixed ring and the annular cleaning brush plate to perform reciprocating vertical displacement, so as to clean the first buffer spring that has metal fatigue and remove dust and dirt on its surface, thereby avoiding corrosion to the first buffer spring, which would cause the elastic performance and life of the first buffer spring that has already suffered metal fatigue to be further reduced. The shockproof effect is improved, the early aging or damage of the distribution cabinet due to vibration is prevented, and the service life of the shockproof distribution cabinet is extended.
[0016] 3. The present invention sets a rotating mechanism so that the guide ball under the annular cleaning brush plate can move along the upper wall of the spiral guide track, thereby driving the annular cleaning brush plate to rotate relative to the fixed ring, so that the annular cleaning brush plate can rotate while vertically displacing, thereby cleaning the dust and dirt attached to the side wall of the first buffer spring, improving the cleaning effect of the first buffer spring, and further increasing the service life of the first buffer spring and the distribution cabinet.
[0017] 4. The present invention sets a transmission mechanism. When the piston plate adjusts the supporting position of the first buffer spring, the second screw rotates synchronously and moves toward the inside of the threaded sleeve, and the hydraulic oil inside the threaded sleeve is transported to the transmission cylinder, so that the piston block moves downward relative to the transmission cylinder, increasing the compression degree of the second buffer spring, realizing synchronous adjustment of the second buffer spring, ensuring that the first buffer spring and the second buffer spring work under the same conditions, ensuring the accuracy and consistency of the buffer spring, and making the cabinet show a more stable buffering effect when vibrated or impacted.

DETAILED DESCRIPTION
[0020] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
[0021] Example: Refer to Figures 1 to 5 , a shockproof power distribution cabinet, comprising: A cabinet body 1, a base 11 is provided below the cabinet body 1, and a plurality of first buffer springs 12 are provided between the cabinet body 1 and the base 11; Specifically, a cabinet door is provided on the side wall of the cabinet body 1 , and the cabinet door cannot be blocked by the infusion tube 22 when opening or closing, thereby ensuring the normal movement of the cabinet body 1 while avoiding affecting the subsequent deviation correction mechanism 2 .
[0022] The correction mechanism 2 is used for automatically adjusting the expansion and contraction amount of the first buffer spring 12 to restore the cabinet 1 to a horizontal position when the cabinet 1 is tilted. The correction mechanism 2 includes a liquid storage tank 21 fixedly connected to the upper end of the cabinet 1, and a plurality of liquid infusion tubes 22 are fixedly connected to the peripheral side walls of the liquid storage tank 21. The upper end of the base 11 is provided with a plurality of correction grooves 23 distributed in a circumferential array, and a piston plate 24 is sealed and slidably connected in the correction groove 23. The space in the correction groove 23 and below the piston plate 24 is connected to the liquid infusion tube 22 at a corresponding position. A first liquid storage space is formed between the liquid storage tank 21, the plurality of liquid infusion tubes 22, and the space in the correction groove 23 below the piston plate 24. The first liquid storage space is filled with hydraulic oil. The first buffer spring 12 is fixedly connected between the upper end of the piston plate 24 and the lower end of the cabinet 1. The lower end of the cabinet 1 is provided with a control component for controlling the correction mechanism 2. Specifically, the control component includes a distance sensor 25 arranged at the lower end of the cabinet 1 and corresponding to each piston plate 24, an opening and closing valve is provided inside the infusion tube 22, and a controller 26 is provided at the upper end of the base 11. The controller 26 controls the opening and closing of the opening and closing valve in the infusion tube 22 at the corresponding position according to the electrical signal transmitted by the distance sensor 25.
[0023] Specifically, an extrusion spring and a sealing extrusion plate are provided inside the liquid storage tank 21. When the opening and closing valve is opened, the elastic force of the extrusion spring can push the extrusion plate to slide in the liquid storage tank 21, thereby squeezing the hydraulic oil in the liquid storage tank 21 into the correction groove 23 at the corresponding position.
[0024] In view of the problem in the prior art that after a long period of vibration, impact or use, the first buffer spring 12 is subjected to long-term stress, which may cause metal fatigue and gradually weaken the elastic force, or the elastic coefficients of some springs are different, resulting in differences, causing the shockproof distribution cabinet to tilt or become unstable, causing the internal components of the shockproof distribution cabinet to malfunction, posing a major safety hazard. The present invention provides a correction mechanism 2. When the distribution cabinet is not vibrated during use, the distance between the bottom of the cabinet 1 and the base 11 is monitored by multiple distance sensors 25. When the cabinet 1 tilts, the distance sensor 25 on the tilted side detects that the distance between the bottom of the cabinet 1 and the base 11 at this position is smaller than that at other positions, so that the on-off valve in the infusion pipe 22 at this position is opened by the controller 26. At this time, due to the tilt of the cabinet 1, the liquid storage tank 21 is tilted. The compression spring and the extrusion plate can, under the elastic force of the extrusion spring, transport the hydraulic oil inside the liquid storage tank 21 through the infusion pipe 22 to the correction groove 23 on the inclined side, so that the piston plate 24 in the correction groove 23 is displaced upward, and then the reference surface at the bottom of the first buffer spring 12 at this position is displaced upward, thereby increasing the compression degree of the first buffer spring 12 on the inclined side, so that the elastic force of the first buffer spring 12 is restored to the same as that at other positions, thereby driving the cabinet body 1 to return to a horizontal state, and being able to adjust the height of the bottom support position of the first buffer spring 12 when metal fatigue occurs, thereby avoiding tilting or instability of the shockproof distribution cabinet, and at the same time extending the service life of the first buffer spring 12, eliminating the need for frequent replacement of the first buffer spring, and reducing the workload of the staff. In addition, after the correction is completed, the controller 26 automatically closes the opening and closing valve to avoid excessive delivery of hydraulic oil.
[0025] The cleaning mechanism 3 is provided with a plurality of cleaning mechanisms 3 and is driven by the piston plates 24 at the corresponding positions respectively, and is used for automatically cleaning the first buffer spring 12 at the position during the deviation correction work.
[0026] The cleaning mechanism 3 includes a first screw 31 rotatably connected to the inside of the deviation correction groove 23, the piston plate 24 is threadedly connected to the first screw 31, and the friction coefficient between the first screw 31 and the piston plate 24 is less than the tangent value of the thread helix angle, the lower end of the first screw 31 is fixedly connected to a driving gear 32, and the positions on both sides of the driving gear 32 in the base 11 are meshed and connected with transmission gears 33, and the upper end of the transmission gear 33 is coaxially fixedly connected to a reciprocating screw 34, and the reciprocating screw 34 is threaded with a lifting screw Block 35, sliding cavities 36 are provided in the base 11 and at positions on both sides of the correction groove 23, the lifting block 35 is slidably connected to the inner wall of the sliding cavity 36 at the corresponding position, an extension rod 37 is fixedly connected to the lifting block 35, the upper end of the extension rod 37 passes through the base 11 and is fixedly connected to a fixing ring 38, the inner wall of the fixing ring 38 is rotatably connected to an annular cleaning brush plate 39, and a rotating mechanism 4 is also provided below the annular cleaning brush plate 39, which is used to rotate the annular cleaning brush plate 39 while moving in the vertical direction.
[0027] Specifically, the diameter of the driving gear 32 is greater than the diameter of the transmission gear 33. Therefore, even if the displacement of the piston plate 24 is small and the driving gear 32 rotates a small number of times, it can also drive the transmission gear 33 to rotate a large number of times, thereby ensuring the cleaning effect of the annular cleaning brush plate 39 on the first buffer spring 12.
[0028] In view of the problem in the prior art that after the power distribution cabinet has been used for a long time, dust and dirt are easily attached to the surface of the buffer spring, which in turn causes corrosion to the buffer spring, resulting in weakened elastic force of the buffer spring, inability to effectively absorb vibration or impact, reduced shockproof effect, and further causing the entire power distribution cabinet to age or be damaged prematurely due to vibration, thereby shortening the service life. In the present invention, a cleaning mechanism 3 is provided. Since the friction coefficient between the first screw 31 and the piston plate 24 is less than the tangent value of the thread helix angle, the first screw 31 and the piston plate 24 are in a non-self-locking state. When the piston plate 24 moves to adjust the first buffer spring 12, it will drive the first The screw rod 31 rotates, and further drives the reciprocating screw rod 34 to rotate through the driving gear 32 and the transmission gear 33, so that the lifting block 35 can perform reciprocating vertical displacement, and drives the fixing ring 38 and the annular cleaning brush plate 39 to perform reciprocating vertical displacement through the extension rod 37, so as to clean the first buffer spring 12 that has metal fatigue, remove dust and dirt on its surface, avoid corrosion to the first buffer spring 12, and cause the elasticity and life of the first buffer spring 12 that has already suffered metal fatigue to be further reduced, thereby improving the shockproof effect, preventing the distribution cabinet from premature aging or damage due to vibration, and extending the service life of the shockproof distribution cabinet.
[0029] The rotating mechanism 4 includes a guide rod 41 fixedly connected to the lower end of the annular cleaning brush plate 39, an annular guide groove 42 is opened at the upper end of the base 11, and the part of the guide rod 41 extending into the annular guide groove 42 is fixedly connected with a guide ball 43. Specifically, the guide rod 41 is L-shaped, and the inner wall of the annular guide groove 42 is fixedly connected with a spiral guide track 44. The guide ball 43 is in conflict with the spiral guide track 44, and a torsion spring 45 is provided between the lower end of the annular cleaning brush plate 39 and the upper end of the base 11.
[0030] It is worth mentioning that the present invention sets a rotating mechanism 4. Since the annular cleaning brush plate 39 always has a tendency to twist downward under the elastic force of the torsion spring 45, when the annular cleaning brush plate 39 performs reciprocating vertical displacement, the guide ball 43 below the annular cleaning brush plate 39 is able to move along the upper wall of the spiral guide track 44, thereby driving the annular cleaning brush plate 39 to rotate relative to the fixed ring 38, so that the annular cleaning brush plate 39 can rotate while vertically displacing, thereby sweeping away dust and dirt attached to the side walls of the first buffer spring 12, thereby improving the cleaning effect of the first buffer spring 12, and further improving the service life of the first buffer spring 12 and the distribution cabinet.
[0031] A second buffer spring 5 for providing more shock absorbing and damping is provided between the base 11 and the cabinet body 1. Specifically, when the distribution cabinet vibrates, not only the first buffer spring 12 can be compressed, but also the buffer block 64 can be displaced in the transmission cylinder 62 to compress the second buffer spring 5. The arrangement of the first buffer spring 12 and the second buffer spring 5 can provide more shock absorbing and damping, and can more effectively disperse and absorb vibrations, thereby enhancing the overall shock absorbing effect.
[0032] A transmission mechanism 6 is also provided between the base 11 and the cabinet 1, which is used to synchronously adjust the expansion and contraction amount of the second buffer spring 5 when adjusting the expansion and contraction amount of the first buffer spring 12. The transmission mechanism 6 includes a second screw 61 coaxially fixedly connected to the upper end of the first screw 31, and a plurality of transmission cylinders 62 distributed in a circular array are fixedly connected in the cabinet 1. The internal sealing and sliding connection of the transmission cylinder 62 is connected to a piston block 63. The second buffer spring 5 is fixedly connected to the lower end of the piston block 63, and the lower end of the second buffer spring 5 is fixedly connected to a buffer block 64. The buffer block 64 is slidably connected to the inner wall of the transmission cylinder 62. A threaded sleeve 65 that is airtightly threadedly connected to the second screw 61 is fixedly connected in the transmission cylinder 62 and located below the buffer block 64. A hydraulic component is provided between the interior of the threaded sleeve 65 and the space in the transmission cylinder 62 above the piston block 63.
[0033] Specifically, the threaded rod and the threaded sleeve can be sealed and connected. This sealing connection is usually used in situations where leakage of liquid, gas or other substances needs to be prevented. This is an existing mature technology, so it will not be elaborated on.
[0034] The hydraulic assembly includes an infusion hose 66 fixedly connected to the inside of the side wall of the transmission cylinder 62, one end of the infusion hose 66 extends to above the piston block 63 and is connected to the space above the piston block 63, the other end of the infusion hose 66 is connected to the inside of the threaded sleeve 65, and a second liquid storage space is formed between the inside of the threaded sleeve 65, the infusion hose 66 and the space above the piston block 63 in the transmission cylinder 62, and the second liquid storage space is filled with hydraulic oil.
[0035] Specifically, two limit blocks are fixedly connected inside the transmission cylinder 62 and below the buffer block 64. The limit blocks can prevent the buffer block 64 from moving downward and squeezing the infusion hose 66, thereby preventing damage to the infusion hose 66 and making it impossible to adjust the second buffer spring 5.
[0036] In addition, the present invention sets a transmission mechanism 6. When the piston plate 24 moves to drive the first screw 31 to rotate and adjusts the support position of the first buffer spring 12, the second screw 61 will rotate synchronously and move toward the inside of the threaded sleeve 65, so that the hydraulic oil inside the threaded sleeve 65 is transported to the position above the piston block 63 in the transmission cylinder 62 through the infusion hose 66, so that the piston block 63 moves downward relative to the transmission cylinder 62, driving the reference surface at the top of the second buffer spring 5 to move downward, increasing the compression degree of the second buffer spring 5, and realizing synchronous adjustment of the second buffer spring 5, ensuring that the first buffer spring 12 and the second buffer spring 5 work under the same conditions, ensuring the accuracy and consistency of the buffer springs, so that the cabinet 1 exhibits a more stable buffering effect when subjected to vibration or impact.
[0037] In addition, it should be noted that shock absorption is the conversion of vibration energy into internal energy generated by sliding friction. In essence, the spring only continuously accumulates and releases elastic potential energy, but the consumption is the consumption of vibration energy through friction. Where there is friction, there is energy dissipation.
[0038] The present invention can be explained by the following operation mode: When the power distribution cabinet is not vibrated during use, the distance between the bottom of the cabinet 1 and the base 11 is monitored by multiple distance sensors 25. When the cabinet 1 tilts, the distance sensor 25 on the tilted side detects that the distance between the bottom of the cabinet 1 and the base 11 at this position is smaller than that at other positions, so that the on-off valve in the infusion pipe 22 at this position is opened by the controller 26, so that the hydraulic oil inside the liquid storage tank 21 is transported to the correction groove 23 on the tilted side, so that the piston plate 24 in the correction groove 23 moves upward, increasing the compression degree of the first buffer spring 12 on the tilted side, so that the elastic force of the first buffer spring 12 is restored to the same as that at other positions, thereby driving the cabinet 1 to return to a horizontal state; When the piston plate 24 moves to adjust the first buffer spring 12, it will drive the first screw rod 31 to rotate, and further drive the reciprocating screw rod 34 to rotate through the driving gear 32 and the transmission gear 33, so that the lifting block 35 can reciprocate vertically, and drive the fixing ring 38 and the annular cleaning brush plate 39 to reciprocate vertically through the extension rod 37, so as to clean the first buffer spring 12 with metal fatigue; When the annular cleaning brush plate 39 performs reciprocating vertical displacement, the guide ball 43 below the annular cleaning brush plate 39 is able to move along the upper wall of the spiral guide track 44, thereby driving the annular cleaning brush plate 39 to rotate relative to the fixing ring 38, so that the annular cleaning brush plate 39 can rotate while performing vertical displacement, thereby improving the cleaning effect of the first buffer spring 12; When the piston plate 24 moves to drive the first screw 31 to rotate and adjust the supporting position of the first buffer spring 12, the second screw 61 will rotate synchronously and move into the threaded sleeve 65, and the hydraulic oil inside the threaded sleeve 65 will be transported to the position above the piston block 63 in the transmission cylinder 62, so that the piston block 63 moves downward relative to the transmission cylinder 62, increasing the compression degree of the second buffer spring 5, realizing synchronous adjustment of the second buffer spring 5, and ensuring that the first buffer spring 12 and the second buffer spring 5 work under the same conditions.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
