[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides a technical solution:

[0029] See also Figures 1 to 7 A mechanical dustproof device comprises a storage box 1, a dustproof cloth 101 is arranged inside the storage box 1, a rotating rod 2 is rotatably arranged inside the storage box 1, and the dustproof cloth 101 is wound around the outside of the rotating rod 2;

[0030] A rotating plate 201 is provided at the lower end of the storage box 1, and the rotating plate 201 is fixedly connected to the lower end of the rotating rod 2. A plurality of counterweights 203 are fixedly connected to the outer portion of the lower side of the dustproof cloth 101 through a pull rope. The counterweights 203 are located between the rotating plate 201 and the storage box 1, and grooves are provided at positions corresponding to the rotating plate 201 and the counterweights 203, and the counterweights 203 are located inside the grooves.

[0031] A thread groove 205 is provided inside the rotating rod 2, and an extrusion rod 206 is slidably installed inside the rotating rod 2. A first ball 207 is embedded in the outer wall of the extrusion rod 206 at a position corresponding to the thread groove 205. The extrusion rod 206 extrudes the inner wall of the thread groove 205 through the first ball 207.

[0032] A moving block 3 is fixedly installed on the upper end of the rotating rod 2, and a moving groove 102 is opened at a position corresponding to the moving block 3 on the upper side of the storage box 1. The moving block 3 slides up and down inside the moving groove 102. A moving plate 103 is also slidably installed inside the moving groove 102. A plurality of second balls 104 are embedded on the upper end of the moving plate 103. The cross section of the moving block 3 is a "T"-shaped structure. The lower end of the upper side of the moving block 3 is in frictional contact with the balls. A plurality of column wheels 105 are rotatably connected between the moving plate 103 and the storage box 1, and the column wheels 105 squeeze the dustproof cloth 101.

[0033] A squeezing spring 106 is fixedly mounted at the lower end of the moving plate 103, and the lower end of the squeezing spring 106 is fixedly connected to the lower end of the inner wall of the moving groove 102;

[0034] Two annular grooves 209 are formed inside the rotating rod 2. The two annular grooves 209 are connected to the upper end and the lower end of the thread groove 205 respectively. The end of the annular groove 209 close to the thread groove 205 is inclined.

[0035] A plurality of push rods 210 are fixedly installed at the lower end of the upper protruding part of the extrusion rod 206. An opening 211 is opened at the position corresponding to the push rod 210 at the upper end of the storage box 1. The opening 211 is connected to the inside of the movable groove 102. The lower end of the push rod 210 passes through the opening 211 and is in extrusion contact with the upper end of the movable block 3.

[0036] By adopting the above technical solution, first, when it is necessary to cover the mechanical equipment for dust prevention, the squeezing rod 206 is pressed down so that the squeezing rod 206 drives the first ball 207 to descend. When the first ball 207 descends, it can squeeze the inner wall of the threaded groove 205, thereby driving the rotating rod 2 to rotate under the action of the squeezing force. After the rotating rod 2 rotates, it can drive the counterweight block 203 on its outer side to rotate through the groove. After the counterweight block 203 rotates, centrifugal force can be generated. After the squeezing rod 206 descends one end distance, the push rod 210 can be inserted into the opening 211. As the squeezing rod 206 continues to descend, the push rod 210 can squeeze the upper end of the moving block 3, causing the moving block 3 to descend and squeeze the second ball 104 to cause the moving plate 103 to descend. The descent of the moving plate 103 can squeeze the squeezing spring 106, so that the squeezing spring 10 6 contracts, and when the moving block 3 descends, it can drive the rotating rod 2 and the rotating plate 201 to descend. The descent of the rotating plate 201 can increase the gap between the rotating plate 201 and the storage box 1. At this time, the column wheel 105 no longer squeezes the dustproof cloth 101. At the same time, under the action of the counterweight block 203 and the centrifugal force, the dustproof cloth 101 can be pulled to move around, so that the dustproof cloth 101 is opened. When the dustproof cloth 101 is opened, it can cover the outside of the mechanical equipment. Among them, when the first ball 207 is located in the annular groove 209, the squeezing rod 206 no longer moves. The rotating rod 2 can still rotate relative to the squeezing rod 206. Since the end of the annular groove close to the threaded groove 205 is an inclined structure, the first ball 207 can automatically enter the threaded groove 205 when the squeezing rod 206 descends or rises.

[0037] Specifically, a movable groove 301 is provided on the inner wall of the movable block 3, a clamping block 302 is slidably installed inside the movable groove 301, a return spring 303 is fixedly installed between the clamping block 302 and the movable groove 301, and the return spring 303 squeezes the clamping block 302. A clamping groove 107 is provided at a position corresponding to the clamping block 302 on the inner wall of the movable groove 102, and the clamping block 302 is clamped and matched with the clamping groove 107;

[0038] A first magnet 304 is embedded in one end of the clamping block 302 away from the return spring 303 , and a second magnet 208 is embedded in the outer wall of the extrusion rod 206 at a position corresponding to the first magnet 304 , and the second magnet 208 repels the first magnet 304 .

[0039] By adopting the above technical solution, when the squeezing rod 206 rises to a certain position, the position of the second magnet 208 corresponds to the position of the first magnet 304. At this time, the first magnet 304 can drive the block 302 to move under the action of the repulsive force, and the block 302 can move to the inside of the movable groove 301. After that, the squeezing spring 106 can squeeze the moving plate 103 under the action of its own toughness, so that the moving plate 103 rises, thereby causing the moving block 3 and the rotating rod 2 to rise. After the rotating rod 2 rises, it can drive the rotating plate 201 to rise. After the rotating plate 201 rises, it can clamp the dustproof cloth 101 again;

[0040] A first through hole 212 is opened inside the extrusion rod 206, and the first through hole 212 penetrates the extrusion rod 206 and extends to its upper side. The interior of the rotating rod 2 is hollow. A second through hole 213 is opened at the lower end of the rotating plate 201. The second through hole 213, the rotating rod 2, and the first through hole 212 form an ash suction channel.

[0041] By adopting the above technical solution, after the dustproof cloth 101 covers the mechanical equipment, the dust suction device is aligned with the first through hole 212 at the upper end of the extrusion rod 206 and suction is performed. At this time, the dust stuck to the surface of the mechanical equipment can be sucked away through the second through hole 213 and the rotating rod 2.

[0042] Working principle: When the mechanical equipment needs to be covered for dust prevention, the extrusion rod 206 is pressed down so that the extrusion rod 206 drives the first ball 207 to descend. When the first ball 207 descends, it can squeeze the inner wall of the thread groove 205, thereby driving the rotating rod 2 to rotate under the action of the extrusion force. After the rotating rod 2 rotates, it can drive the counterweight block 203 on its outer side to rotate through the groove. After the counterweight block 203 rotates, centrifugal force can be generated. After the extrusion rod 206 descends one end distance, the push rod 210 can be inserted into the opening 211. As the extrusion rod 206 continues to descend, the push rod 210 can squeeze the upper end of the moving block 3. The moving block 3 is made to descend and squeeze the second ball 104 to make the moving plate 103 descend. The descending of the moving plate 103 can squeeze the squeezing spring 106, so that the squeezing spring 106 contracts. When the moving block 3 descends, it can drive the rotating rod 2 and the rotating plate 201 to descend. The descending of the rotating plate 201 can increase the gap between the rotating plate 201 and the storage box 1. At this time, the column wheel 105 no longer squeezes the dustproof cloth 101. At the same time, under the action of the counterweight block 203 and the centrifugal force, the dustproof cloth 101 can be pulled to move around, so that the dustproof cloth 101 is opened. When the dustproof cloth 101 is opened, it can cover On the outside of the mechanical device, when the first ball 207 is located inside the annular groove 209, the extrusion rod 206 no longer moves and the rotating rod 2 can still rotate relative to the extrusion rod 206. Since the end of the annular groove close to the thread groove 205 is inclined, the first ball 207 can automatically enter the thread groove 205 when the extrusion rod 206 descends or rises. After the top rod 210 squeezes the moving block 3, the moving block 3 can be lowered. When the moving block 3 descends, the movable groove 301 can squeeze the block 302 inside it to make the block 302 descend. When the moving block 3 descends to When at the lowest end, the position of the block 302 is aligned with the position of the slot 107. At this time, under the action of the return spring 303, the block 302 can move relative to the movable slot 301. After moving, the block 302 can extend from the inside of the movable slot 301, thereby getting stuck in the slot 107 to fix the movable block 3. When the dustproof cloth 101 needs to be retracted, the rotating plate 201 is rotated so that the dustproof cloth 101 is wound around the outside of the rotating rod 2, and then the squeezing rod 206 is pulled upward to align the position of the second magnet 208 with the position of the first magnet 304, thereby disengaging the block 302 from the slot 107.
