Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and particularly relates to a high electromagnetic shielding power equipment housing for preventing vibration displacement. Background Art

[0002] Power equipment is an indispensable infrastructure for modern industry and daily life, mainly including two categories: power generation equipment and power supply equipment. Power generation equipment covers power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc., while power supply equipment includes transmission lines, instrument transformers, contactors, etc. of various voltage levels. These equipment will generate or be affected by high electromagnetic interference during operation, which will affect the normal operation and safety of the equipment. In order to protect power equipment from electromagnetic interference, a corresponding shielding housing is usually required.

[0003] During the use of common power equipment shielding housings, due to the vibration of the internal power equipment, the power equipment may move within the shielding housing or the shielding housing may shake. The stability of the power equipment and the shielding housing during use is not good. At the same time, when it is necessary to move the shielding housing and the internal power equipment as a whole, it usually requires manual handling by staff, and the shielding housing and the internal power equipment will shake during the handling process. When the shielding housing is moved by rotating the wheels at the bottom of the shielding housing on the ground, vibrations will also occur due to uneven ground. When in use, it is impossible to move the shielding housing on the ground without contacting the ground, thereby reducing the vibration of the shielding housing and the internal power equipment.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, the staff energizes a plurality of electromagnet blocks on the outer walls of the two installation shells to make the electromagnet blocks generate a magnetic field. The two protective rings are made of iron. During use, the outer wall of the installation shell and the inner wall of the iron protective ring can maintain a certain distance through the repulsive force of the magnetic field. A plurality of distance sensors on the inner wall of the protective ring can monitor the distances at different positions between the outer wall of the installation shell and the inner wall of the protective ring in real time. When the distances at different positions between the outer wall of the installation shell and the inner wall of the protective ring are different, the magnetic field intensity of the electromagnet blocks at the specified positions is increased by the current and the energization of the electromagnet blocks, so that the repulsive force of the magnetic field of the electromagnet blocks pushes the inner wall of the protective ring. The position of the installation shell can be quickly adjusted through the magnetic fields of the plurality of electromagnet blocks, and it is convenient for the protective ring to roll without contact on the outer wall of the installation shell when the whole equipment shell is moved, improving the stability of the installation shell, the installation plate and the power equipment thereon during movement.

[0018] 2. In the present invention, the support columns can lower the overall center of gravity of the equipment shell through their own weight, improving the overall stability of the shell. At the same time, when installing the power equipment, the support columns can support the power equipment and cooperate with the moving plates and the inner walls of the fixing holes to fix the position of the power equipment, preventing the power equipment from sliding on the top of the installation plate due to vibration during use.

[0019] 3. In the present invention, the staff can select 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 moving plates at both ends inside the fixing hole are respectively abutted against both sides of the power equipment, and the power equipment is clamped and fixed by the reinforcing plates on the moving plates on both sides of the power equipment. During use, the support columns, the moving plates and the inner walls of the fixing holes cooperate with each other to fix the position of the power equipment well, preventing the power equipment from moving on the installation plate due to the vibration of the power equipment during use.

[0020] 4. In the present invention, when the installed power equipment is small in volume, the staff can install several moving plates inside the fixing holes. The several moving plates are in contact with each other to seal the inside of the fixing holes. Then the staff place the power equipment on the top of the moving plates and fix the bottom end of the power equipment to the top of the moving plates through fixing bolts. The mounting plate fixes the position of the power equipment through the guiding grooves and the moving plates.

[0021] 5. In the present invention, when the staff needs to move the equipment housing and the power equipment inside it as a whole, the staff rotate the support plate into the installation groove. At the same time, the suction cups are disconnected from the desktop or the ground through the pressing blocks. Then the staff can push the rotating plate to drive the installation shell, the mounting plate and the power equipment on it to move. The two protective rings rotate without contact on the outer walls of the two installation shells respectively. At the same time, the protective rings roll on the ground. When the staff needs to move the equipment housing and the power equipment inside it, there is no need for the staff to lift and move the equipment housing, which is more convenient to use and can provide better protection and stability for the power equipment during movement.

When in use, the staff can place a certain amount of moving plates 15 inside the fixing holes 22, and the power equipment 18 can be installed and fixed or clamped and limited by the moving plates 15, making the power equipment 18 more stable during use.

[0035] As a technical optimization solution of the present invention, both ends of the moving plate 15 are respectively slidably installed inside the two guide grooves 24. Screw holes 20 are provided at both ends of the top of the moving plate 15. Grooves 28 are provided at both ends of the side of the two mounting shells 9 close to the mounting plate 1. Support columns 13 are installed below the mounting plate 1. Both ends of the support columns 13 are respectively located inside the grooves 28 on the two mounting shells 9. The support columns 13 can support the bottom end of the power equipment 18 during use, cooperate with the fixing holes 22 and the moving plates 15 to limit the power equipment 18. At the same time, the support columns 13 are located below the mounting plate 1, which can make the support columns 13 lower the overall center of gravity of the mounting plate 1 and the power equipment 18 through their own weights and the mounting shells 9, improving the stability of the power equipment 18 and the overall housing.

[0036] As a technical optimization solution of the present invention, a power equipment 18 is placed in the middle of the fixing holes 22. The bottom end of the power equipment 18 abuts against the top of the support column 13. The top end of the power equipment 18 is located above the mounting plate 1. Both sides of the power equipment 18 respectively abut against the moving plates 15 at both ends inside the fixing holes 22. When in use, the staff can install the moving plates 15 on both sides of the power equipment 18 inside the fixing holes 22 according to the width and size of the installed power equipment 18, so that the moving plates 15 at both ends inside the fixing holes 22 abut against the inner walls of the fixing holes 22, and the moving plates 15 close to the power equipment 18 abut against the sides of the power equipment 18.

[0037] As a technical optimization solution of the present invention, connection blocks 7 are installed on both sides of the mounting plate 1. Arc-shaped rotating plates 2 are rotatably installed at the positions close to the edges of the top and bottom of the mounting plate 1. One end of the rotating plate 2 close to the mounting plate 1 is rotatably connected to the connection block 7. When in use, the staff can rotate the rotating plate 2, which is convenient for the staff to install and disassemble the power equipment 18.

[0038] As a technical optimization solution of the present invention, the opposite surfaces of the two rotating plates 2 on the same side of the mounting plate 1 are in mutual contact. A plurality of fixing blocks 8 are installed at positions on the outer wall of one of the rotating plates 2 on the same side of the mounting plate 1 close to the opposite surface, and a plurality of engaging blocks 17 are installed at positions on the outer wall of the other rotating plate 2 close to the opposite surface. The four rotating plates 2 on both sides of the mounting plate 1 can cooperate with each other to seal the space inside the four rotating plates 2.

[0039] As a technical optimization solution of the present invention, a slot 30 is opened at the bottom end of the side surface of the fixing block 8. The engaging block 17 is located inside the slot 30. A micro telescopic rod 31 is installed on the side of the fixing block 8 away from the rotating plate 2. A suction cup 32 is installed at the end of the micro telescopic rod 31 away from the fixing block 8. A pressing block 11 is installed on the outer wall of the end of the micro telescopic rod 31 away from the fixing block 8. During use, the staff can press the pressing block 11 on the micro telescopic rod 31 below the mounting plate 1, so that the suction cup 32 on the micro telescopic rod 31 is connected and fixed to the tabletop or the ground, and the rotating plate 2 and the mounting plate 1 are fixed in position through the suction cup 32 and the fixing block 8.

[0040] As a technical optimization solution of the present invention, placing grooves 21 are opened in the length direction on both sides of the fixing holes 22 at the top and bottom of the mounting plate 1. An electromagnetic shielding cloth 14 is installed on the inner wall of the rotating plate 2 through a magic tape. The bottom end of the electromagnetic shielding cloth 14 is installed on the inner wall of the placing groove 21. During use, the staff can place the electromagnetic shielding cloth 14 inside the placing groove 21 according to the usage situation, or paste the electromagnetic shielding cloth 14 on the inner wall of the rotating plate 2 through the magic tape, so that the electromagnetic shielding cloth 14 performs electromagnetic shielding on the periphery of the power device 18.

[0041] As a technical optimization solution of the present invention, L-shaped reinforcing blocks 16 are installed at both ends of the top of the two moving plates 15 on both sides of the power device 18. A fixing bolt 26 is installed at the top and bottom of the reinforcing block 16. The bottom end of the fixing bolt 26 penetrates through the reinforcing block 16 and is threadedly installed inside the screw hole 20. A rubber pad 25 is installed on the side of the top end of the reinforcing block 16 close to the power device 18. The reinforcing block 16 can cooperate with the inner walls on both sides of the fixing hole 22 during use to clamp both sides of the power device 18.

[0042] As a technical optimization solution of the present invention, air inlet holes 19 are provided on the inner walls at both ends of the fixing hole 22. One end of the air inlet hole 19 penetrates into the interior of the mounting shell 9. An air filter 12 and an air extraction pump 27 are respectively installed on the inner walls of the two mounting shells 9. The air filter 12 and the air extraction pump 27 are respectively communicated with the two air inlet holes 19. On both sides of the corners of the two moving plates 15 near the air inlet holes 19 at both ends inside the fixing hole 22, flow guiding corners are provided; during use, the air filter 12 filters the external air and conveys it into the interiors of the four rotating plates 2 to cool the power equipment 18.

[0043] When the present invention is in use, the staff puts protective rings 3 on the mounting shells 9 at both ends of the mounting plate 1, and rotates the support plates 6 located inside the mounting grooves 5 on both sides of the outer wall at 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. During 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 during use, the four support plates 6 are all in an arc shape, making the mounting plate 1 and the mounting shell 9 more stable during use. The staff rotates the two rotating plates 2 located below the mounting plate 1, so that the space below the mounting plate 1 communicates with the outside. The staff can insert both ends of the support column 13 into the grooves 28 below the mounting plate 1 on the opposite surfaces of the two mounting shells 9. During use, the support column 13 can connect the two mounting shells 9. The support column 13 is a telescopic support column 13, which is convenient for the staff to install, disassemble and replace the installation position of the support column 13. During use, the support column 13 can lower the overall center of gravity of the equipment shell by its own weight, improving the overall stability performance of the shell. At the same time, when installing the power equipment 18, the support column 13 can support the power equipment 18, and cooperate with the inner walls of the moving plate 15 and the fixing hole 22 to fix the position of the power equipment 18, preventing the power equipment 18 from sliding on the top of the mounting plate 1 due to vibration during use.

[0044] After the staff finishes installing the support column 13, the staff pulls the electromagnetic shielding cloth 14 placed in the placement grooves 21 on both sides at the bottom of the mounting 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 the electromagnetic shielding cloth 14 is installed on the inner wall of the rotating plate 2 through Velcro. The staff pushes the rotating plate 2 towards the support column 13 until the opposite surfaces of the two rotating plates 2 located below the mounting plate 1 abut against each other. At the same time, the clamping block 17 on one of the rotating plates 2 is inserted into the clamping groove 30 on the fixing block 8 on the outer wall of the other rotating plate 2. During use, the fixing block 8 and the clamping block 17 can connect and fix the two rotating plates 2, preventing the two rotating plates 2 from disconnecting due to the vibration of the power equipment 18, resulting in the disconnection of the electromagnetic shielding cloth 14 on the inner wall of the rotating plate 2 from shielding the electromagnetic field of the power equipment 18.

[0045] The staff presses down the pressing block 11 on the outer wall of the micro telescopic rod 31 of the fixing block 8, so that the bottom end of the micro telescopic rod 31 drives the suction cup 32 thereon to move down until the suction cup 32 adsorbs on the desktop or the ground. During use, the suction cup 32 can better limit the positions of the two rotating plates 2 through the fixing block 8, making the rotating plates 2 more stable during use, and at the same time, the two rotating plates 2 can also be supported by the micro telescopic rod 31.

[0046] The staff rotates the two rotating plates 2 above the mounting plate 1 and installs the power equipment 18 to be used. During use, the staff can select different installation methods according to the overall volume of the power equipment 18. When the overall volume of the power equipment 18 is relatively large, the staff first installs several moving plates 15 at both ends inside the fixing holes 22 through the limiting grooves 23, and both ends of the moving plates 15 are respectively located inside the two guiding grooves 24. The staff places the power equipment 18 in the middle end inside the fixing holes 22, so that the bottom end of the power equipment 18 is located on the top of the support column 13, and the top end of the power equipment 18 is located above the mounting plate 1. During use, the moving plates 15 at both ends inside the fixing holes 22 are respectively abutted against both sides of the power equipment 18, and the staff can install the reinforcing blocks 16 on the tops of the two moving plates 15 close to both sides of the power equipment 18 and fix the reinforcing blocks 16 and the moving plates 15 through the fixing bolts 26. The reinforcing blocks 16 on both sides of the power equipment 18 clamp and fix both sides of the power equipment 18 through the rubber pads 25 thereon. During use, the support column 13, the moving plates 15 and the inner wall of the fixing holes 22 cooperate with each other to fix the position of the power equipment 18 well, preventing the power equipment 18 from moving on the mounting plate 1 due to the vibration of the power equipment 18 during use.

[0047] When the volume of the installed power equipment 18 is relatively small, the staff can install several moving plates 15 inside the fixing holes 22, and several moving plates 15 are abutted against each other to seal the inside of the fixing holes 22. The staff places the power equipment 18 on the top of the moving plates 15 and fixes the bottom end of the power equipment 18 to the top of the moving plates 15 through the fixing bolts 26. The mounting plate 1 fixes the position of the power equipment 18 through the guiding grooves 24 and the moving plates 15. The staff installs the electromagnetic shielding cloth 14 placed inside the placing groove 21 on the top of the mounting plate 1 on the inner walls of the two rotating plates 2 above through the magic tape, and rotates the two rotating plates 2 so that the opposite surfaces at the top ends of the two rotating plates 2 are abutted against each other and are connected to each other through the fixing block 8 and the clamping block 17. During use, the four electromagnetic shielding cloths 14 can isolate the electromagnetic field around the power equipment 18.

[0048] During use, the staff energizes a number of electromagnet blocks 10 on the outer walls of the two mounting shells 9, causing the electromagnet blocks 10 to generate a magnetic field. The two protective rings 3 are made of iron. During use, the outer walls of the mounting shells 9 and the inner walls of the iron protective rings 3 can maintain a certain distance through the repulsive force of the magnetic field. At the same time, a number of distance sensors 29 on the inner walls of the protective rings 3 can continuously monitor the distances at different positions between the outer walls of the mounting shells 9 and the inner walls of the protective rings 3. 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 intensity of the electromagnet blocks 10 at the specified position is increased by increasing the current and energizing the electromagnet blocks 10, so that the repulsive force of the magnetic field of the electromagnet blocks 10 pushes the inner wall of the protective ring 3. During use, when the shaking amplitude of the mounting plate 1 is large, the electromagnet blocks 10 can quickly adjust the position of the mounting shell 9 through the magnetic fields of the number of electromagnet blocks 10. At the same time, the micro telescopic rods 31, the suction cups 32 and the fixing blocks 8 can also support and stabilize the lower part of the equipment shell.

[0049] During use, the air filter 12 filters the outside air and conveys it between the four rotating plates 2 to cool the power equipment 18. The cooled gas can be conveyed to the outside again through the air extraction pump 27. During use, the temperature of the power equipment 18 and the internal spaces of the four rotating plates 2 can be continuously cooled. When the staff needs to move the equipment shell and the internal power equipment 18 as a whole, the staff can rotate the support plate 6 on the outer wall of the protective ring 3 so that the support plate 6 rotates into the installation groove 5. At the same time, the pressing block 11 is pulled to disconnect the suction cup 32 from the desktop or the ground. Then 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. The two protective rings 3 rotate without contact on the outer walls of the two mounting shells 9. At the same time, the protective rings 3 roll on the ground. Because there is no contact between the mounting shell 9 and the protective ring 3, when the protective ring 3 rotates on the ground and there is a slight vibration, the mounting shell 9, the mounting plate 1 and the power equipment 18 will not vibrate. When the staff needs to move the equipment shell and the internal power equipment 18, there is no need for the staff to lift and move the equipment shell, which is more convenient during use and can provide better protection and stability for the power equipment 18 during movement.

[0050] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
