DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods: like Figure 1 , Figure 2 As shown, the present invention provides a protective device for power distribution control equipment, including a base 10, a buffer shock absorbing component 2 is arranged on the top of the base 10, a distribution cabinet housing 11 is arranged on the top of the buffer shock absorbing component 2, a sealing door 12 is hinged on the front side of the distribution cabinet housing 11, a handle 13 is fixedly connected to the front left side of the sealing door 12, ventilation holes 14 are opened on the top of the left and right sides of the distribution cabinet housing 11, a PLC controller 15 is fixedly connected to the right inner wall of the distribution cabinet housing 11, a temperature sensor 16 is fixedly connected to the rear side of the right inner wall of the distribution cabinet housing 11, a humidity sensor 17 is fixedly connected to the front side of the right inner wall of the distribution cabinet housing 11, the PLC controller 15 is electrically connected to the temperature sensor 16 and the humidity sensor 17 respectively, a filter cleaning component 3 is arranged below the left side wall of the distribution cabinet housing 11, and a plurality of distribution equipment clamping components 4 arranged at equal distances are fixedly connected to the rear inner wall of the distribution cabinet housing 11.

[0018] The base 10 is made of metal material as a whole, and has sufficient strength and stability to support the weight of the entire protective device and the internal power distribution control equipment. The right inner wall of the distribution cabinet housing 11 is respectively installed with a temperature sensor 16 and a humidity sensor 17, which can sense the temperature and humidity conditions inside the distribution cabinet in real time and transmit the electrical signal to the PLC controller 15. After receiving these signals, the PLC controller 15 starts the heat dissipation fan 34, which generates airflow by rotating blades to extract the hot air inside the distribution cabinet to achieve the heat dissipation function. A filter 36 is arranged on the left side of the heat dissipation fan 34, and the filter 36 is used to prevent dust and other impurities from entering the distribution cabinet.

[0019] like Figure 3 As shown, the buffer shock absorbing assembly 2 includes four hollow columns 20, the bottoms of the four hollow columns 20 are fixedly connected to the four corners of the top of the base 10, the inner bottoms of the four hollow columns 20 are fixedly connected with springs 22, the tops of the four springs 22 are fixedly connected with lifting columns 21 slidably connected to the inner walls of the hollow columns 20, the tops of the four lifting columns 21 are fixedly connected to the four corners of the bottom of the distribution cabinet housing 11, the opposite surfaces of the front and rear hollow columns 20 are fixedly connected with a cross plate 23, the top of the cross plate 23 is fixedly connected with a plurality of dampers 24 distributed equidistantly front and rear, and the tops of the plurality of dampers 24 are fixedly connected to the bottom of the distribution cabinet housing 11.

[0020] like Figure 3As shown, the opposite surfaces of the left and right hollow columns 20 are fixedly connected with a slide bar 25, and the outer walls of the slide bar 25 are slidably connected with sliders 26 on both sides. The opposite surfaces of the left and right sliders 26 are fixedly connected with a spring 27 sleeved on the outer wall of the slide bar 25. The front sides of the left and right sliders 26 are rotatably connected with a connecting rod 28, and the ends of the left and right connecting rods 28 away from the sliders 26 are rotatably connected to the bottom of the distribution cabinet housing 11. The left and right connecting rods 28 are cross-arranged and rotatably connected in the middle.

[0021] When the switch cabinet housing 11 is subjected to impact force, the switch cabinet housing 11 will produce an up-and-down displacement. At this time, the lifting columns 21 fixedly connected to the four corners of the bottom of the switch cabinet housing 11 will slide up and down in the hollow column 20 together with the switch cabinet housing 11. Since a spring 22 is fixedly connected to the bottom of the hollow column 20, the spring 22 will be compressed or stretched according to the up-and-down movement of the lifting column 21. The spring 22 uses its own elastic deformation characteristics to absorb and buffer part of the impact force, thereby reducing the vibration effect on the switch cabinet housing 11 and the internal power distribution equipment. At the same time, the damper 24 can further consume the vibration energy and achieve a better buffering and shock absorbing effect. In addition, when the switch cabinet housing 11 shakes in the left and right directions, the rotation of the connecting rod 28 will cause the slider 26 to move on the slide rod 2 5 slides relatively on the upper surface, and the spring 27 is compressed or stretched accordingly. The spring 27 uses its own elastic force to resist the sliding of the slider 26, thereby buffering the shaking of the distribution cabinet housing 11 in the left and right directions, and works in coordination with the shock-absorbing mechanism in the up and down directions to protect the distribution cabinet housing 11 and the internal equipment from vibration in all directions. The buffer and shock-absorbing component 2 set can effectively absorb and buffer these vibrations, prevent the vibration from being directly transmitted to the precise power distribution control equipment inside the distribution cabinet, and avoid the loosening, desoldering, damage, etc. of the electronic components and line connections inside the equipment due to frequent vibration, thereby greatly extending the service life of the distribution equipment. At the same time, the existence of the buffer and shock-absorbing component 2 can effectively suppress the collision and friction caused by vibration, significantly reduce the noise generated during the operation of the distribution cabinet, and create a relatively quiet working environment.

[0022] like Figure 4 As shown, the filter cleaning assembly 3 includes two fixed plates 30, the right sides of the upper and lower fixed plates 30 are fixedly connected to the lower left wall of the distribution cabinet housing 11, the opposite front sides of the upper and lower fixed plates 30 are rotatably connected with a reciprocating screw rod 31, the opposite rear sides of the upper and lower fixed plates 30 are fixedly connected with the reciprocating screw rod 31, the top front side of the upper fixed plate 30 is fixedly connected with a motor 1 33, and the output end of the motor 1 33 passes through the bottom of the upper fixed plate 30 and is fixedly connected to the reciprocating screw rod 31.

[0023] like Figure 4As shown, a cooling fan 34 is fixedly connected to the bottom of the left side wall of the distribution cabinet housing 11, and a filter screen 36 fixedly connected to the left outer wall of the distribution cabinet housing 11 is arranged on the left side of the cooling fan 34. A cleaning brush 35 is threadedly connected to the outer wall of the reciprocating screw 31 and is slidably connected to the outer wall of the slide rod 2 32. The bristles of the cleaning brush 35 are in contact with the left side wall of the filter screen 36, and the PLC controller 15 is electrically connected to the motor 1 33 and the cooling fan 34 respectively.

[0024] As the cooling fan 34 works for a long time, dust may accumulate on the filter 36, affecting the cooling effect. At this time, the PLC controller 15 will regularly start the motor 1 33, and the motor 1 33 drives the reciprocating screw 31 to rotate. The outer wall of the reciprocating screw 31 is threadedly connected with a cleaning brush 35. Under the guidance of the sliding rod 2 32, the cleaning brush 35 will reciprocate along the left side wall of the filter 36 as the reciprocating screw 31 rotates, thereby cleaning the dust accumulated on the filter 36, ensuring the air permeability of the filter 36, and maintaining a good cooling effect. Through the filter cleaning component 3 set, the filter 36 can be cleaned regularly to remove dust and other impurities attached to the filter 36, ensuring the air permeability of the filter 36, so that the cooling fan 34 can smoothly extract and discharge the hot air inside the distribution cabinet, thereby maintaining a good cooling effect, ensuring that the distribution control equipment operates in a suitable temperature environment, and avoiding problems such as equipment overheating, performance degradation or even damage due to poor heat dissipation.

[0025] like Figure 5 , Figure 6 As shown, the power distribution equipment clamping assembly 4 includes a fixed base 40, the rear side wall of the fixed base 40 is fixedly connected to the rear inner wall of the power distribution cabinet housing 11, the front side of the fixed base 40 is fixedly connected to a fixed frame 41, the right side of the fixed frame 41 is fixedly connected to a motor 2 42, the output end of the motor 2 42 passes through the interior of the fixed frame 41 and is fixedly connected to a main gear 43, the front side of the main gear 43 is meshedly connected to a slave gear 44, the interior of the slave gear 44 is fixedly connected to a double-headed screw 45, the left and right ends of the double-headed screw 45 respectively pass through the left and right outer walls of the fixed frame 41 and are rotatably connected to the fixed frame 41.

[0026] like Figure 5 , Figure 6 As shown, a slide rod 3 46 is fixedly connected to the inner front side of the fixed frame 41, and the left and right ends of the slide rod 3 46 respectively penetrate the left and right outer walls of the fixed frame 41 and are fixedly connected to a limiting block 47, and the left and right sides of the outer wall of the double-headed screw 45 are threadedly connected to moving blocks 49 that are slidably connected to the outer wall of the slide rod 3 46, and the front sides of the left and right moving blocks 49 are fixedly connected to clamping blocks 48.

[0027] like Figure 5 , Figure 6As shown, the PLC controller 15 is electrically connected to the second motor 42, and the opposing surfaces of the left and right clamping blocks 48 are both provided with anti-slip materials.

[0028] When it is necessary to clamp the power distribution equipment, the PLC controller 15 controls the motor 2 42 to start, and the output end of the motor 2 42 drives the main gear 43 to rotate, and the main gear 43 is meshed with the slave gear 44. The rotation of the main gear 43 will drive the slave gear 44 to rotate, and the double-headed screw 45 fixedly connected inside the slave gear 44 will also rotate accordingly. When the double-headed screw 45 rotates, the left and right moving blocks 49 will move towards or away from each other. When the moving blocks 49 move towards each other, the clamping block 48 will gradually clamp the power distribution equipment, and increase the friction force through the anti-slip material to ensure that the power distribution equipment is firmly fixed in the power distribution cabinet to prevent it from shaking, thereby ensuring the normal operation and safety of the power distribution equipment. When it is necessary to disassemble the power distribution equipment, the PLC controller 15 controls The brake motor 42 rotates in the opposite direction, causing the clamp 48 to release the power distribution equipment. Through the power distribution equipment clamping assembly 4, the device can firmly clamp the power distribution equipment, effectively preventing the power distribution equipment from shaking in the power distribution cabinet, ensuring that the connection parts such as the wiring terminals of the power distribution equipment always maintain a stable connection state, avoiding loose wiring due to shaking, and thus ensuring the normal power supply and signal transmission of the power distribution system. At the same time, the power distribution equipment clamping assembly 4 allows the operator to easily remove the power distribution equipment from the power distribution cabinet without the need to laboriously disassemble other complex fixing devices or worry about damaging the equipment, which greatly shortens the time for equipment maintenance and reduces the impact of equipment maintenance on the operation of the entire power distribution system.

[0029] It should be noted that the PLC controller 15, the temperature sensor 16, the humidity sensor 17, the damper 24, and the heat dissipation fan 34 are all prior arts and will not be described in detail herein.

[0030] The following is a detailed description of the working principle of the protective device of the power distribution control equipment.

[0031] like Figure 1-6 As shown, first, the right inner wall of the distribution cabinet housing 11 is respectively installed with a temperature sensor 16 and a humidity sensor 17, which can sense the temperature and humidity conditions inside the distribution cabinet in real time, and transmit the electrical signal to the PLC controller 15. After receiving these signals, the PLC controller 15 starts the heat dissipation fan 34, which generates airflow through rotating blades to extract the hot air inside the distribution cabinet to achieve the heat dissipation function. A filter 36 is arranged on the left side of the heat dissipation fan 34, and the filter 36 is used to prevent dust and other impurities from entering the distribution cabinet.

[0032] When the switch cabinet housing 11 is subjected to impact force, the switch cabinet housing 11 will produce an up-and-down displacement. At this time, the lifting columns 21 fixedly connected to the four corners of the bottom of the switch cabinet housing 11 will slide up and down in the hollow column 20 together with the switch cabinet housing 11. Since a spring 22 is fixedly connected to the bottom of the hollow column 20, the spring 22 will be compressed or stretched according to the up-and-down movement of the lifting column 21. The spring 22 uses its own elastic deformation characteristics to absorb and buffer part of the impact force, thereby reducing the vibration effect on the switch cabinet housing 11 and the internal power distribution equipment. At the same time, the damper 24 can further consume the vibration energy and achieve a better buffering and shock absorbing effect. In addition, when the switch cabinet housing 11 shakes in the left and right directions, the rotation of the connecting rod 28 will cause the slider 26 to move on the slide rod 2 5 slides relatively on the upper surface, and the spring 27 is compressed or stretched accordingly. The spring 27 uses its own elastic force to resist the sliding of the slider 26, thereby buffering the shaking of the distribution cabinet housing 11 in the left and right directions, and works in coordination with the shock-absorbing mechanism in the up and down directions to protect the distribution cabinet housing 11 and the internal equipment from vibration in all directions. The buffer and shock-absorbing component 2 set can effectively absorb and buffer these vibrations, prevent the vibration from being directly transmitted to the precise power distribution control equipment inside the distribution cabinet, and avoid the loosening, desoldering, damage, etc. of the electronic components and line connections inside the equipment due to frequent vibration, thereby greatly extending the service life of the distribution equipment. At the same time, the existence of the buffer and shock-absorbing component 2 can effectively suppress the collision and friction caused by vibration, significantly reduce the noise generated during the operation of the distribution cabinet, and create a relatively quiet working environment.

[0033] As the cooling fan 34 works for a long time, dust may accumulate on the filter 36, affecting the cooling effect. At this time, the PLC controller 15 will regularly start the motor 1 33, and the motor 1 33 drives the reciprocating screw 31 to rotate. The outer wall of the reciprocating screw 31 is threadedly connected with a cleaning brush 35. Under the guidance of the sliding rod 2 32, the cleaning brush 35 will reciprocate along the left side wall of the filter 36 as the reciprocating screw 31 rotates, thereby cleaning the dust accumulated on the filter 36, ensuring the air permeability of the filter 36, and maintaining a good cooling effect. Through the filter cleaning component 3 set, the filter 36 can be cleaned regularly to remove dust and other impurities attached to the filter 36, ensuring the air permeability of the filter 36, so that the cooling fan 34 can smoothly extract and discharge the hot air inside the distribution cabinet, thereby maintaining a good cooling effect, ensuring that the distribution control equipment operates in a suitable temperature environment, and avoiding problems such as equipment overheating, performance degradation or even damage due to poor heat dissipation.

[0034] When the power distribution equipment needs to be clamped, the PLC controller 15 controls the motor 2 42 to start, and the output end of the motor 2 42 drives the main gear 43 to rotate, and the main gear 43 is meshed with the slave gear 44. The rotation of the main gear 43 drives the slave gear 44 to rotate, and the double-headed screw 45 fixedly connected inside the slave gear 44 also rotates accordingly. When the double-headed screw 45 rotates, the left and right moving blocks 49 will move towards or away from each other. When the moving blocks 49 move towards each other, the clamping block 48 will gradually clamp the power distribution equipment, and increase the friction through the anti-slip material to ensure that the power distribution equipment is firmly fixed in the power distribution cabinet to prevent it from shaking, thereby ensuring the normal operation and safety of the power distribution equipment. When the power distribution equipment needs to be disassembled, the PLC controller 15 controls the motor 2 42 to rotate in the opposite direction, so that the clamping block 48 releases the power distribution equipment. Through the set power distribution equipment clamping component 4, the device can firmly clamp the power distribution equipment, effectively preventing the power distribution equipment from shaking in the power distribution cabinet, ensuring that the connection parts such as the wiring terminals of the power distribution equipment always maintain a stable connection state, avoiding loose wiring due to shaking, and thus ensuring the normal power supply and signal transmission of the power distribution system. At the same time, the set power distribution equipment clamping component 4 enables the operator to easily remove the power distribution equipment from the power distribution cabinet without the need to laboriously disassemble other complex fixing devices or worry about damaging the equipment, which greatly shortens the equipment maintenance time and reduces the impact of equipment maintenance on the operation of the entire power distribution system.

[0035] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
