The function of the arrangement is that the driving block 5 drives the connecting frame 18, the clamping mechanism and the film element on the connecting frame to do square wave-shaped reciprocating and vertical movement on the plane parallel to the fixed plate 3, so that the spraying mechanism 2 does square wave-shaped reciprocating and vertical movement relative to the film element, and the film element is fully washed in the moving mode (in order to save the water consumption for washing the film element, the spraying area of the spraying mechanism 2 is reduced as much as possible, and the length and the width of the spraying area are smaller than those of the film element, so that the spraying mechanism 2 and the film element need to relatively do horizontal and vertical movement to fully wash the film element); when the driving block 5 moves to the edge of the driving groove 4 (i.e. the tail end of the horizontal groove 41 or the tail end of the vertical groove 42), the driving block 5 slightly impacts the inner wall of the driving groove 4 under the driving of the power mechanism, so that the film element on the clamping mechanism can be driven to vibrate to a certain extent, and the film element intermittently vibrates (at the edges of the multi-section horizontal groove 41 and the vertical groove 42, i.e. intermittently vibrates) in the process of flushing the film element by the spraying mechanism 2, thereby improving the cleaning effect and accelerating the process of cleaning pollutants on the film element; when the chemical agent is soaked in the membrane element, the driving block 5 moves along the driving groove 4 to drive the membrane element to move in the chemical agent (namely, the membrane element moves in the chemical agent and performs intermittent vibration), meanwhile, the chemical agent is stirred to a certain extent through the clamping mechanism on the driving block 5 and the membrane element, so that the chemical agent in the cleaning cavity is fully contacted with the membrane element, the cleaning efficiency of the membrane element is improved as much as possible, and the aeration operation during soaking of the conventional chemical agent can be saved (the aeration operation can be performed simultaneously with the conventional aeration operation, and the cleaning efficiency of the membrane element is further improved).
Still further, the fixing groove 20 is constructed on the driving block 5. Specifically, the connecting frame 18 is connected with the fixing groove 20 of the driving block 5 through the fixing rod 21, that is, the whole connecting frame 18 can be mounted on the driving block 5 through the fixing rod 21 or dismounted from the driving block 5, after the fixing rod 21 is put into the fixing groove 20, the relative positions of the driving block 5 and the fixing rod 21 can be limited through bolts or bolts and the like, so that the connecting frame 18 and the driving block 5 can be conveniently mounted and dismounted.
Still further, the horizontal drive subassembly includes vertical sliding connection lifting block 6 on fixed plate 3, the last rotation of lifting block 6 is connected with drive screw 7, drive screw 7 and drive block 5 threaded connection. Specifically, the lifting block 6 can slide along the vertical direction of the fixed plate 3, when the driving block 5 is positioned in the horizontal groove 41, the driving screw 7 rotates to drive the driving block 5 to move along the horizontal groove 41, when the driving block 5 is positioned in the vertical groove 42, the driving block 5 ascends or descends along the vertical groove 42 under the action of gravity of the vertical driving component, and in the process that the driving block 5 moves along the vertical groove 42, the lifting block 6 synchronously slides along the vertical direction of the fixed plate 3, and the lifting block further comprises a power source (such as a motor, not shown) which is arranged on the lifting block 6, wherein the power source is used for driving the driving screw 7 to rotate forward or reversely, so that the driving block 5 can be driven to horizontally reciprocate through the power source and the driving screw 7, and when the driving block 5 horizontally reciprocates, the driving block 5 can be synchronously driven to vertically reciprocate through the operation of the vertical driving component, and then the driving block 5 is driven to reciprocate along the driving groove 4 in a square wave shape; when the driving screw 7 drives the driving block 5 to move to the end of the horizontal groove 41, the driving block 5 slightly impacts the end of the horizontal groove 41 to drive the membrane element to slightly vibrate.
Still further, vertical drive assembly includes vertical sliding connection first rack 8 and sliding plate 9 on fixed plate 3, be provided with the elastic component between first rack 8 and the fixed plate 3, it is provided with gear 10 to rotate on the sliding plate 9, sliding connection has second rack 11 on the sliding plate 9, first rack 8 and second rack 11 all mesh with gear 10, still include the joint spare, it is used for carrying out the joint to drive block 5 and second rack 11. Specifically, a sliding groove is vertically formed in the fixed plate 3, the sliding plate 9 is in sliding connection with the sliding groove, the first rack 8 is arranged along the vertical direction of the fixed plate 3, a guide post 12 is fixed on the fixed plate 3, a guide groove for the guide post 12 to move is formed in the first rack 8, the guide post 12 is polygonal and is inserted into the guide groove, so that the guide post can only vertically slide and cannot rotate, an elastic piece is preferably two first springs 13 symmetrically arranged, the two first springs 13 are respectively sleeved at the upper end and the lower end of the guide post 12, the two ends of the first springs 13 are respectively fixedly connected with the fixed plate 3 and the first rack 8, so that the first rack 8 is forced to be positioned at an original position on the guide post 12 through the first springs 13, the second rack 11 is horizontally arranged and can slide along the horizontal direction of the sliding plate 9, and the first rack 8 and the second rack 11 are staggered in the depth direction (the direction perpendicular to the fixed plate 3) and are meshed with the gear 10; when the driving block 5 needs to ascend along the driving groove 4 (ascending of the whole travel), the driving block 5 moves to a position close to the vertical groove 42 along the horizontal groove 41, the driving block 5 and the second rack 11 are clamped through a clamping piece (the clamping piece can be a clamping piece controlled by an electric push rod, and the clamping piece can be clamped with a groove body on the second rack 11 when extending out of the driving block 5), after the clamping is completed, continued movement of the drive block 5 along the horizontal slot 41 will squeeze the second rack 11 (via the snap-fit engagement against the inner wall of the slot), since the second rack 11 is in sliding connection with the sliding plate 9, the second rack 11 is extruded and then moves horizontally relative to the sliding plate 9, so that the gear 10 is driven to rotate when the second rack moves, and then the first rack 8 is driven by the gear 10 to move downwards along the guide post 12, when the first rack 8 moves downwards, the first spring 13 is stretched or extruded (both ends of the first rack 8 are respectively provided with the first spring 13, when the first rack moves downwards, the first spring 13 is stretched or extruded), at this time, the driving block 5 is interfered by the upper wall of the horizontal groove 41, and cannot move vertically under the action of the elastic force of the first spring 13 until the driving block 5 completely moves to the inside of the vertical groove 42, the top of the driving block 5 is not limited any more, and the first rack 8, the sliding plate 9, the gear 10, the second rack 11 and the driving block 5 are driven to synchronously rise into the next horizontal groove 41 under the elastic force of the first spring 13, then the driving block 5 can continue to move along the next horizontal groove 41 (the clamping between the driving block 5 and the second rack 11 is released during the movement), so that the driving of the driving block 5 along the driving groove 4 is completed; when the driving block 5 descends along the driving groove 4 (the whole travel descends), the driving block moves to a position close to the vertical groove 42 along the horizontal groove 41, the clamping piece does not work (namely the clamping machine head does not extend to be clamped with the groove body), so that the driving block 5 can directly move into the vertical groove 42, and the driving block 5 is driven to descend into the next horizontal groove 41 along the vertical groove 42 under the action of the gravity of the horizontal driving component, so that the driving of the driving block 5 descending along the driving groove 4 is completed; after the driving block 5 ascends along the driving groove 4 and moves to the next horizontal groove 41 from the vertical groove 42, and the second rack 11 is released from the clamping connection with the driving block 5, the sliding plate 9 slides downwards under the action of gravity, and in the process of downward movement of the sliding plate 9, the position of the first rack 8 is basically unchanged, so that the gear 10 rotates when moving downwards, and meanwhile, the second rack 11 is driven to horizontally move until the sliding plate 9, the gear 10 and the second rack 11 are reset to the original positions, so that the next clamping connection with the driving block 5 is facilitated, and the driving block 5 is driven to move upwards along the vertical groove 42.
The advantage of this arrangement is that firstly, the horizontal driving assembly continuously works and drives the driving block 5 to horizontally reciprocate, when the driving block 5 moves to a position close to the vertical groove 42 along the horizontal groove 41, under the action of the structures such as the first rack 8 and the second rack 11, the driving block 5 can be driven to rise into the next horizontal groove 41 passively, or the driving block 5 is driven to fall into the next horizontal groove 41 under the action of gravity, so that the driving block 5 can be driven to continuously and continuously move along the driving groove 4 along square-wave-shaped track, so that the film element on the clamping mechanism moves relative to the spraying mechanism 2 and the film element is washed comprehensively; secondly, when driving the driving block 5 through the first spring 13 and ascending along the vertical groove 42, the elasticity of the first spring 13 can drive the driving block 5 to strike the top wall of the vertical groove 42, so can drive the membrane element on the clamping mechanism to vibrate to a greater extent, further improve the cleaning effect and accelerate the process of removing pollutants on the membrane element, and correspondingly, the driving block 5 can strike the bottom wall of the vertical groove 42 when descending along the vertical groove 42 under the action of gravity, and can also drive the membrane element to vibrate to a certain extent.
It should be noted that, the elastic coefficient of the first spring 13 is larger, the lifting block 6 and the driving screw 7 are made of light materials (the power source of the driving screw 7 is smaller and the power is larger), because the horizontal movement of the driving block 5 is driven by the driving screw 7, and the transmission ratio of the driving screw 7 is larger, the driving screw 7 has enough power to drive the driving block 5 to squeeze the second rack 11 so as to force the first rack 8 to squeeze the first spring 13 to move, and when the first spring 13 is reset, the elastic potential energy of the first spring 13 is enough to drive the structures of the first rack 8, the sliding plate 9, the driving block 5, the lifting block 6, the film element and the like to synchronously move; the elastic coefficient of the first spring 13 is determined based on the height of the vertical groove 42, so that when the driving block 5 extrudes the second rack 11, the deformation amount of the first rack 8 compressing the first spring 13 is slightly larger than the height of the vertical groove 42 (so that the elastic potential energy accumulated by the first spring 13 is enough to drive the driving block 5 to impact the inner wall of the driving groove 4 to a certain extent), and when the first spring 13 is reset, the driving block 5 is driven to move to the top of the vertical groove 42 to enter the next horizontal groove 41 to move continuously; the height of the sliding groove corresponds to the height of the vertical groove 42, that is, the sliding distance of the sliding plate 9 along the sliding groove is the same as the sliding distance of the driving block 5 along the vertical groove 42, so that after the driving block 5 is clamped with the second rack 11, the driving block 5 and the sliding plate 9 synchronously move for a certain distance.
In still another embodiment of the present invention, further, the clamping member includes a clamping block 14 slidably connected to the driving block 5, a clamping groove 141 is configured on the clamping block 14, and a clamping rod 15 adapted to the clamping groove 141 is fixed on the second rack 11. Specifically, the driving block 5 is provided with a chute 16 along the direction of the vertical fixing plate 3, the clamping block 14 is slidably connected in the chute 16, two clamping grooves 141 are symmetrically formed at two ends of the clamping block 14, and the two clamping grooves 141 are respectively used for clamping the clamping rods 15 at two sides of the fixing plate 3. When the driving block 5 ascends along the driving groove 4, the clamping block 14 is automatically moved to one side of the sliding groove 16 far away from the fixed plate 3 (such as an electric push rod or an electric telescopic rod) by driving the clamping block 14 through a linear driving mechanism, at this time, the clamping groove 141 is aligned with the clamping rod 15, so that when the driving block 5 moves along the horizontal groove 41, the clamping rod 15 can be inserted into the corresponding clamping groove 141, thereby driving the driving block 5 to ascend along the vertical groove 42 through the vertical driving component until the driving block 5 moves to the tail end above the driving groove 4, and when the driving block 5 returns and descends along the driving groove 4, the clamping block 14 is moved to one side of the sliding groove 16 near the fixed plate 3, at this time, the clamping block 14 is dislocated with the clamping rod 15, and both the driving block 5 and the clamping block 14 are positioned on one side of the clamping rod 15 near the fixed plate 3, that is, when the driving block 5 descends along the driving groove 4, the driving block 5 does not contact with the second rack 11, so that the driving block 5 can descend along the vertical groove 42 under the action of self gravity. The advantage of this arrangement is that the state of the driving block 5 can be changed by adjusting the position of the clamping block 14, so that the driving block can be clamped with the clamping rod 15 or not clamped with the clamping rod 15, and the driving block 5 can be adapted to the ascending or descending stroke.
It should be noted that, after the clamping rod 15 abuts against the inner wall of the clamping groove 141, the driving block 5 continues to move a certain distance to reach the end of the horizontal groove 41, and the distance is the same as the deformation of the first spring 13, that is, after the driving block 5 is clamped with the second rack 11, the moving distance of the first rack 8 and the second rack 11 is the same until the driving block 5 completely enters the vertical groove 42.
Furthermore, trigger mechanisms are arranged at two ends of the driving groove 4, the trigger mechanisms force the clamping blocks 14 to be aligned with the clamping rods 15 at the bottom end of the driving groove 4, and the trigger mechanisms force the clamping blocks 14 to be dislocated with the clamping rods 15 at the top end of the driving groove 4. Specifically, the trigger mechanism includes two trigger blocks 17 fixed on the upper and lower sides of the fixed plate 3, the two trigger blocks 17 are respectively located at two ends of the driving slot 4, one side of the two trigger blocks 17 close to the driving slot 4 is respectively provided with an inclined plane, and the angles of the two inclined planes are opposite, so that the clamping block 14 is forced to move along the chute 16 through the inclined planes on the two trigger blocks 17, that is, when the driving block 5 moves to the upper end along the driving slot 4, the clamping block 14 can squeeze the inclined plane of the upper trigger block 17, so that the clamping block 14 moves to one side of the chute 16 close to the fixed plate 3, correspondingly, when the driving block 5 moves to the lower end along the driving slot 4, the clamping block 14 can squeeze the inclined plane of the lower trigger block 17, so that the clamping block 14 moves to one side of the chute 16 far away from the fixed plate 3, and the driving block 5 is driven to reciprocate along the driving slot 4, in the reciprocating movement process of the driving block 5, that the clamping block 14 can pass through the upper end and lower end of the driving slot 4, so that the clamping block 14 is forced to move to the clamping block 15 or the lower end of the driving rod is not adapted to the stroke of the driving rod.
