Description

Technical Field

[0001] The invention relates to the technical field of electric equipment, and in particular to a high electromagnetic shielding electric equipment housing that is resistant to vibration displacement. Background Art

[0002] Power equipment is an indispensable infrastructure for modern industry and daily life. It mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment covers power station boilers, steam turbines, gas turbines, water turbines, generators and transformers, while power supply equipment includes transmission lines of various voltage levels, mutual inductors, contactors, etc. These devices will generate or be subject to high electromagnetic interference during operation, affecting the normal operation and safety of the equipment. In order to protect power equipment from electromagnetic interference, it is usually necessary to equip it with corresponding shielding casing.

[0003] When in use, a common shielding shell of power equipment may cause the power equipment to move or shake inside the shielding shell due to the vibration of the power equipment inside it. The stability of the power equipment and the shielding shell is poor during use. At the same time, when the shielding shell and the power equipment inside it need to be moved as a whole, staff are usually required to carry them manually. During the transportation process, the shielding shell and the power equipment inside it may shake. When the wheels at the bottom of the shielding shell rotate on the ground to drive the shielding shell to move, it will vibrate due to the uneven ground. When in use, the shielding shell cannot be moved on the ground without contacting the ground, thereby reducing the vibration of the shielding shell and the power equipment inside it.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the staff energizes several electromagnet blocks on the outer walls of the two mounting shells to make the electromagnet blocks generate a magnetic field, and the materials of the two protective rings are both iron. When in use, the electromagnet blocks and the inner walls of the iron protective rings can maintain a certain distance between the outer wall of the mounting shell and the inner wall of the protective ring through the repulsive force of the magnetic field. Several distance sensors on the inner wall of the protective ring can monitor the distance between the mounting shell and the inner wall of the protective ring at different positions in real time. When the distances between the outer wall of the mounting shell and the inner wall of the protective ring are different, the magnetic field strength of the electromagnet block at the specified position is increased by the current and the energization of the electromagnet block, so that the magnetic field repulsive force of the electromagnet block pushes the inner wall of the protective ring. The electromagnet block can quickly adjust the position of the mounting shell through the magnetic field of several electromagnet blocks, and when the device shell is moved as a whole, it is convenient for the protective ring to roll contactlessly on the outer wall of the mounting shell, thereby improving the stability of the mounting shell, the mounting plate and the electrical equipment thereon during movement.

[0016] 2. The support column in the present invention can lower the center of gravity of the entire equipment casing through its own weight, thereby improving the overall stability of the casing. At the same time, when the power equipment is installed, the support column can support the power equipment and cooperate with the movable plate and the inner wall of the fixing hole to fix the position of the power equipment, thereby preventing the power equipment from sliding on the top of the mounting plate due to vibration during use.

[0017] 3. In the present invention, the staff can choose different installation methods according to the overall volume of the power equipment. When the overall volume of the power equipment is large, the power equipment is placed in the middle end of the fixing hole so that the bottom end of the power equipment is located on the top of the support column. The movable plates at both ends of the fixing hole are respectively abutted against the two sides of the power equipment, and the power equipment is clamped and fixed by the reinforcement plates on the movable plates on both sides of the power equipment. When in use, the support column, the movable plate and the inner wall of the fixing hole cooperate with each other to better fix the position of the power equipment and prevent the power equipment from moving on the mounting plate due to the vibration of the power equipment during use.

[0018] 4. In the present invention, when the installed power equipment is small in size, the staff can install several movable plates inside the fixing hole, and the several movable plates abut against each other and seal the inside of the fixing hole. The staff places the power equipment on the top of the movable plate, and fixes the bottom end of the power equipment to the top of the movable plate through fixing bolts. The mounting plate fixes the position of the power equipment through the guide groove and the movable plate.

[0019] 5. In the present invention, when the staff needs to move the device casing and the electrical equipment inside it as a whole, the staff rotates the support plate to the inside of the installation groove, and at the same time, the suction cup is disconnected from the desktop or the ground by the pressure block, and the staff can push the rotating plate to make the rotating plate drive the mounting shell, the mounting plate and the electrical equipment thereon to move, and the two protective rings rotate contactlessly on the outer walls of the two mounting shells respectively, and at the same time the protective rings roll on the ground. When the staff needs to move the device casing and the electrical equipment inside it, the staff does not need to lift and move the device casing, which is more convenient to use and can provide better protection and stability for the electrical equipment during movement.

[0029] As a technical optimization scheme of the present invention, the opposite surfaces of the two rotating plates 2 located on the same side of the mounting plate 1 abut against each other, a plurality of fixing blocks 8 are installed on the outer wall of one of the rotating plates 2 located on the same side of the mounting plate 1 near the opposite surface, and a plurality of clamping blocks 17 are installed on the outer wall of the other rotating plate 2 near the opposite surface; the four rotating plates 2 located on both sides of the mounting plate 1 can cooperate with each other to seal the space inside the four rotating plates 2.

[0030] As a technical optimization solution of the present invention, a card slot 30 is opened at the bottom end of the side of the fixed block 8, and the card block 17 is located inside the card slot 30. A micro telescopic rod 31 is installed on the side of the fixed block 8 away from the rotating plate 2, and a suction cup 32 is installed on the end of the micro telescopic rod 31 away from the fixed block 8. A pressing block 11 is installed on the outer wall of the end of the micro telescopic rod 31 away from the fixed block 8; when in use, the staff can press the pressing block 11 on the micro telescopic rod 31 under the mounting plate 1 to connect and fix the suction cup 32 on the micro telescopic rod 31 to the desktop or the ground, and fix the rotating plate 2 and the mounting plate 1 through the suction cup 32 and the fixed block 8.

[0031] As a technical optimization scheme of the present invention, the top and bottom of the mounting plate 1 are located on both sides of the fixing hole 22 and are provided with placement grooves 21 in the length direction. An electromagnetic shielding cloth 14 is installed on the inner wall of the rotating plate 2 through Velcro, and the bottom end of the electromagnetic shielding cloth 14 is installed on the inner wall of the placement groove 21. When in use, the staff can place the electromagnetic shielding cloth 14 inside the placement groove 21 according to the usage situation, or can stick the electromagnetic shielding cloth 14 to the inner wall of the rotating plate 2 through Velcro, so that the electromagnetic shielding cloth 14 can electromagnetically shield the surrounding area of ​​the power equipment 18.

[0032] As a technical optimization solution of the present invention, L-shaped reinforcement blocks 16 are installed at both ends of the top of the two movable plates 15 located on both sides of the power equipment 18, and a fixing bolt 26 is installed on the top of the bottom end of the reinforcement block 16. The bottom end of the fixing bolt 26 passes through the reinforcement block 16 and is threadedly installed inside the screw hole 20. A rubber pad 25 is installed on the top of the reinforcement block 16 close to the side of the power equipment 18; when in use, the reinforcement block 16 can cooperate with the inner walls on both sides of the fixing hole 22 to clamp the two sides of the power equipment 18.

[0033] As a technical optimization scheme of the present invention, air supply holes 19 are opened on the inner walls at both ends of the fixing hole 22, and one end of the air supply hole 19 penetrates into the interior of the mounting shell 9. Air filters 12 and air pumps 27 are respectively installed on the inner walls of the two mounting shells 9. The air filters 12 and the air pumps 27 are respectively connected to the two air supply holes 19. The two movable plates 15 located at both ends of the fixing hole 22 are provided with guide angles on both sides of the corners near one end of the air supply hole 19. When in use, the air filter 12 filters the outside air and delivers it to the inside of the four rotating plates 2 to cool down the power equipment 18.

[0034] When the present invention is in use, the staff puts the protective ring 3 on the mounting shell 9 at both ends of the mounting plate 1, and rotates the support plate 6 located inside the mounting groove 5 on both sides of the outer wall of the bottom end of the protective ring 3, so that one end of the support plate 6 moves out of the mounting groove 5, and the other end abuts against the inner wall of the mounting groove 5 after rotation. When in use, the four support plates 6 at the bottom ends of the two protective rings 3 support the mounting shell 9 and the mounting plate 1, and when in use, the four support plates 6 are all located in an arc shape, so that the mounting plate 1 and the mounting shell 9 are more stable when in use. The staff rotates the two rotating plates 2 located below the mounting plate 1, so that the space below the mounting plate 1 is interconnected with the outside world, and the staff can insert the two ends of the support column 13 into the groove 28 located below the mounting plate 1 on the opposite surfaces of the two mounting shells 9. When in use, the support column 13 can connect the two mounting shells 9. The support column 13 is a retractable support column 13, which is convenient for the staff to install and disassemble the support column 13 and change the installation position. When in use, the support column 13 can lower the center of gravity of the entire equipment casing through its own weight, thereby improving the overall stability of the casing. At the same time, when the power equipment 18 is installed, the support column 13 can support the power equipment 18, and cooperate with the movable plate 15 and the inner wall of the fixing hole 22 to fix the position of the power equipment 18, thereby preventing the power equipment 18 from sliding on the top of the mounting plate 1 due to vibration during use.

[0035] After the staff has installed the support column 13, the staff pulls the electromagnetic shielding cloth 14 inside the placement grooves 21 on both sides of the bottom of the installation plate 1, so that the electromagnetic shielding cloth 14 moves to the inner wall of the rotating plate 2 close to the support column 13, and installs the electromagnetic shielding cloth 14 on the inner wall of the rotating plate 2 through Velcro. The staff pushes the rotating plate 2 to move in the direction of the support column 13 until the opposite surfaces of the two rotating plates 2 located below the installation plate 1 abut against each other, and at the same time, the block 17 on one of the rotating plates 2 is inserted into the slot 30 on the fixing block 8 on the outer wall of the other rotating plate 2. When in use, the fixing block 8 and the block 17 can connect and fix the two rotating plates 2 to prevent the two rotating plates 2 from being disconnected due to the vibration of the power equipment 18, causing the electromagnetic shielding cloth 14 on the inner wall of the rotating plate 2 to disconnect the electromagnetic shielding of the power equipment 18.

[0036] The staff presses down the pressing block 11 on the micro-telescopic rod 31 on the outer wall of the fixed block 8, so that the bottom end of the micro-telescopic rod 31 drives the suction cup 32 thereon to move downward until the suction cup 32 is adsorbed on the table or the ground. When in use, the suction cup 32 can better limit the position of the two rotating plates 2 through the fixed block 8, making the rotating plates 2 more stable when in use, and at the same time, the two rotating plates 2 can be supported by the micro-telescopic rod 31.

[0037] The staff rotates the two rotating plates 2 above the mounting plate 1 and installs the power equipment 18 to be used. When in use, the staff can choose different installation methods according to the overall volume of the power equipment 18. When the overall volume of the power equipment 18 is large, the staff first installs a plurality of movable plates 15 at both ends of the interior of the fixing hole 22 through the limiting grooves 23, and the two ends of the movable plates 15 are respectively located inside the two guide grooves 24. The staff places the power equipment 18 at the middle end of the interior of the fixing hole 22, so that the bottom end of the power equipment 18 is located at the top of the support column 13, and the top end of the power equipment 18 is located above the mounting plate 1. When in use, the movable plates 15 located at the two ends of the fixing hole 22 are respectively abutted against the two sides of the power equipment 18, and the staff can install the reinforcement blocks 16 on the top of the two movable plates 15 close to the two sides of the power equipment 18, and fix the reinforcement blocks 16 and the movable plates 15 by fixing bolts 26, and the reinforcement blocks 16 located on both sides of the power equipment 18 clamp and fix the two sides of the power equipment 18 by the rubber pads 25 thereon. When in use, the support column 13, the movable plate 15 and the inner wall of the fixing hole 22 cooperate with each other, which can better fix the position of the power equipment 18, and prevent the power equipment 18 from moving on the mounting plate 1 due to the vibration of the power equipment 18 during use.

[0038] When the installed power equipment 18 is small in size, the staff can install several mobile plates 15 inside the fixing hole 22, and the several mobile plates 15 abut against each other, and seal the inside of the fixing hole 22, and the staff places the power equipment 18 on the top of the mobile plate 15, and fixes the bottom end of the power equipment 18 on the top of the mobile plate 15 through the fixing bolts 26, and the mounting plate 1 fixes the position of the power equipment 18 through the guide groove 24 and the mobile plate 15. The staff installs the electromagnetic shielding cloth 14 located inside the placement groove 21 at the top of the mounting plate 1 on the inner walls of the two rotating plates 2 located above through Velcro, and rotates the two rotating plates 2 so that the top opposite surfaces of the two rotating plates 2 abut against each other, and are connected to each other through the fixing block 8 and the clamping block 17. When in use, the four electromagnetic shielding cloths 14 can electromagnetically isolate the surroundings of the power equipment 18.

[0039] When in use, the staff energizes several electromagnet blocks 10 on the outer walls of the two mounting shells 9 to generate a magnetic field. The two protective rings 3 are made of iron. When in use, the electromagnet blocks 10 and the inner walls of the iron protective rings 3 can maintain a certain distance between the outer wall of the mounting shell 9 and the inner wall of the protective ring 3 through the repulsive force of the magnetic field. At the same time, several distance sensors 29 located on the inner wall of the protective ring 3 can monitor the distance between the mounting shell 9 and the inner wall of the protective ring 3 at different positions in real time. When the distance between the outer wall of the mounting shell 9 and the inner wall of the protective ring 3 is short, the magnetic field strength of the electromagnet block 10 at the specified position is increased by the current and the energization of the electromagnet block 10, so that the magnetic field repulsive force of the electromagnet block 10 pushes the inner wall of the protective ring 3. When in use, when the mounting plate 1 shakes a large amplitude, the electromagnet block 10 can quickly adjust the position of the mounting shell 9 through the magnetic field of several electromagnet blocks 10. At the same time, the micro telescopic rod 31, the suction cup 32 and the fixing block 8 can also support and stabilize the bottom of the equipment housing.

[0040] When in use, the air filter 12 filters the outside air and delivers it between the four rotating plates 2 to cool the power equipment 18, and the cooled gas can be delivered to the outside again through the air pump 27, so that the temperature of the power equipment 18 and the internal space of the four rotating plates 2 can be cooled in real time when in use. When the staff needs to move the device housing and the power equipment 18 inside it as a whole, the staff can rotate the support plate 6 on the outer wall of the protective ring 3 to rotate the support plate 6 to the inside of the mounting groove 5, and pull the pressure block 11 at the same time to disconnect the suction cup 32 from the desktop or the ground, and the staff can push the rotating plate 2 to drive the mounting shell 9, the mounting plate 1 and the power equipment 18 thereon to move, and the two protective rings 3 respectively rotate on the outer walls of the two mounting shells 9 without contact, and the protective rings 3 roll on the ground at the same time. Because the mounting shell 9 is not in contact with the protective ring 3, when the protective ring 3 rotates on the ground and vibrates slightly, the mounting shell 9, the mounting plate 1 and the power equipment 18 will not vibrate. When the staff needs to move the device casing and the electric device 18 inside it, the staff does not need to lift and move the device casing, which is more convenient to use and can better protect and stabilize the electric device 18 when moving.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
