Description
Technical Field
[0001] This utility model relates to the field of electrical equipment shielding covers, and in particular to a high-voltage electrical equipment shielding cover that is easy to clean. Background Technology
[0002] A high-voltage electrical equipment shielding cover is a shielding device used in high-voltage electrical systems. The shielding device is made of specific materials, and its core function is to control, isolate, or absorb electric fields, magnetic fields, and electromagnetic radiation, thereby ensuring the stability of equipment operation, personnel safety, and that the surrounding environment is not disturbed.
[0003] In the existing technology, when it is necessary to clean the shielding cover of high-voltage electrical equipment, the high-voltage equipment to which the shielding cover belongs must first be de-energized. After the power is turned off, the staff needs to use a dry soft brush to clean the high-voltage shielding cover to avoid scratching the surface.
[0004] Because workers need to get very close to the shielding of high-voltage electrical equipment, they need to wear specific high-voltage protective clothing during cleaning to reduce the risk of accidental electric shock caused by residual charge during contact. There is still room for improvement. Utility Model Content
[0005] To facilitate the cleaning of high-voltage electrical equipment shielding covers by staff, this utility model provides a high-voltage electrical equipment shielding cover that is easy to clean.
[0006] This utility model provides a shielding cover for high-voltage electrical equipment that is easy to clean, and adopts the following technical solution:
[0007] A high-voltage electrical equipment shielding cover that is easy to clean includes a housing and a cover body. The cover body is equipped with a cleaning brush for cleaning dust. The cleaning brush is equipped with a reset device for driving the cleaning brush to reset and rotate. The reset device is equipped with a drive mechanism for driving the reset device to reset and rotating, and the cleaning brush to rotate. The drive mechanism is equipped with a pull rope for driving the drive mechanism. The drive mechanism is equipped with a fixed pipe for the pull rope to pass through. The housing is equipped with a fixing post for installing the fixed pipe.
[0008] By adopting the above technical solution, when the surface of the top of the cover needs to be cleaned, the pull rope is pulled, and the drive mechanism corresponding to the pull rope moves to make the cleaning brush rotate to clean the surface of the cover. Releasing the pull rope reset device drives the cleaning brush to rotate in the opposite direction so that the cleaning brush resets and cleans the cover a second time. Thus, the cleaning cover can be cleaned by pulling the pull rope from a distance, which is convenient for workers to clean.
[0009] Optionally, the resetter includes a cleaning housing for mounting the cleaning brush, a spring coiler disposed inside the cleaning housing for driving the cleaning housing to rotate, and a spring coiler retaining post for mounting the spring coiler. The cleaning housing has an installation groove for mounting the spring coiler. A rotating bearing is provided between the spring coiler retaining post and the spring coiler. The spring coiler is provided with a cover for mounting the spring coiler. The cover is in contact with the cleaning housing. The cover has a fixing groove for inserting the spring coiler.
[0010] By adopting the above technical solution, the coil spring is placed on the cleaning shell with the coil spring retainer, and the coil spring is fixed by the cover, so that the coil spring is fixed inside the cleaning shell. The rotation of the coil spring retainer is increased by the rotating bearing between the coil spring retainer and the coil spring retainer. Thus, when rotating, the coil spring retainer is rotated to drive the cleaning brush to rotate, and the coil spring retainer is used to reset, so that the cleaning brush can automatically reset.
[0011] Optionally, the spring coiler includes a spring coil and a spring housing for mounting the spring coil. The spring coil holder has a slot for mounting the spring coil inside. The outside of the spring coil is fixedly connected to the spring housing. The spring housing has an insertion hole for mounting the spring coil holder and the rotating bearing.
[0012] By adopting the above technical solution, the coil spring is placed in the coil spring shell, and the inside of the coil spring is engaged in the slot of the coil spring retainer, while the outside is fixed to the coil spring shell. Thus, when the coil spring retainer is rotated, the coil spring generates elastic force. When the force of the coil spring retainer disappears, the elastic force is released, causing the coil spring retainer to reset.
[0013] Optionally, the driving mechanism includes a rotating column mounted on a spring-loaded post and a movable circular block for driving the rotating column to rotate. The cover has an insertion hole for inserting the rotating column. The rotating column rotates in a fixed pipe, and the movable circular block is positioned between the rotating column and the fixed pipe. The fixed pipe has an insertion slot for mounting the rotating column and the movable circular block.
[0014] The movable circular block slides in the fixed pipe, the pull rope is installed on the movable circular block, the movable circular block is provided with a contact bolt for abutting against the rotating column to drive the rotating column to rotate, the movable circular block is provided with a rotating groove for the contact bolt to be installed, the rotating column is provided with a threaded groove for the contact bolt to abut against; the movable circular block is provided with a slider, and the fixed pipe is provided with a sliding groove for the slider to slide.
[0015] By adopting the above technical solution, the contact bolt on the moving block is connected to the threaded groove of the rotating column. The pull rope pulls the moving block, so that the slider on the moving block can only slide in the groove, thereby converting the linear motion of the moving block into the rotation of the rotating column. The rotation of the rotating column drives the coil spring locking column to rotate, which in turn makes the sweeping brush rotate.
[0016] Optionally, the fixed pipe includes an installation pipe fixed to the cover, a connecting pipe disposed on the side of the installation pipe away from the cover, and a tapered pipe disposed on the side of the connecting pipe away from the installation pipe. The connecting pipe is sleeved on the fixed column, and the pull rope passes through the tapered pipe, the connecting pipe and the installation pipe in sequence to connect to the movable circular block.
[0017] By adopting the above technical solution, the pull rope is sequentially threaded through the cone tube, the connecting tube, and the installation tube to be installed on the connecting block. The worker pulls the pull rope to make the connecting block move up and down, thereby driving the cleaning brush to rotate.
[0018] Optionally, the rotating column is provided with a threaded rod that is threadedly engaged with the spring retainer. The threaded rod is used to fix the rotating column on the spring retainer. The rotating column and the spring retainer are provided with rotating grooves for the threaded rod to be threadedly engaged.
[0019] By adopting the above technical solution, a threaded rod is installed on the rotating column and the coil spring retainer, and the rotating column is fixed on the coil spring retainer by the threaded rod, thereby restricting the movement of the rotating column and restricting the ejection of the coil spring.
[0020] Optionally, a mounting bearing is provided between the rotating column and the cover, and the cover has a bearing groove for mounting the bearing.
[0021] By adopting the above technical solution, a bearing is installed between the rotating column and the cover. By installing the bearing, the rotation of the rotating column and the cover caused by friction is reduced, thereby allowing the rotating column to slide between the rotating column and the cover, reducing the friction between the rotating column and the cover.
[0022] Optionally, the cleaning brush includes a cleaning bracket disposed on the cover for cleaning the cover and a cleaning strip disposed on the cleaning bracket, wherein the cleaning bracket has a slot for inserting and installing the cleaning strip.
[0023] By adopting the above technical solution, a cleaning strip is placed on the cleaning bracket, and the cleaning strip is installed by inserting it into the insertion slot on the cleaning bracket, thereby cleaning the cover by installing the cleaning strip on the cleaning bracket.
[0024] Optionally, the cleaning bracket is provided with a fixing member for fixing the cleaning strip, and the fixing member is provided with an inserter that is inserted into a slot.
[0025] By adopting the above technical solution, a fixing component is provided on the mounting bracket. After the cleaning strip is inserted, the fixing component is inserted into the insertion slot to limit the cleaning strip, thereby fixing the cleaning strip and realizing the replacement of the cleaning strip.
[0026] Optionally, the fastener is provided with a snap-fit block for fixedly engaging with the cleaning bracket, and the cleaning bracket is provided with a snap-fit groove for the snap-fit block to snap into.
[0027] By adopting the above technical solution, a snap-fit block is provided on the fixing component. The snap-fit block snaps into the snap-fit groove of the cleaning bracket. After snapping, the fixing component is fixed on the cleaning bracket, thereby further improving the fixation between the fixing block and the cleaning bracket through the snap-fit block.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. The cleaning hood is cleaned by pulling the pull rope from a distance, making it convenient for staff to clean.
[0030] 2. During rotation, the cleaning brush is driven to rotate by rotating the spring retainer, and then reset by the spring coiler, so that the cleaning brush can automatically reset.
[0031] 3. This allows for the fixing of the cleaning strip via fasteners, and also enables the replacement of the cleaning strip. Attached Figure Description
