DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] Figure 1-Figure 2 This is an embodiment of the utility model: a coarse grille cleaning device, comprising a left slide rail 1 and a right slide rail 2 horizontally arranged on both sides of the coarse grille plate, a cleaning brush 3 is installed between the left slide rail 1 and the right slide rail 2, and the cleaning brush 3 is used to remove debris on the coarse grille tooth rake by horizontally moving contact on the coarse grille plate.

[0025] Among them, in order to use a reciprocating design to solve the problem of debris on the coarse grid plate tooth rake, in this technical solution, a slide groove 4 is provided on both the left slide rail 1 and the right slide rail 2, and a reciprocating motion mechanism 5 is installed on the slide groove 4 to drive the cleaning brush 3 to move horizontally back and forth on the coarse grid plate. Its specific structure includes a slider 51 horizontally slidingly connected in the slide groove 4, a column block 52 is welded on one side of the slider 51, and a linkage rod 54 is contact-mounted on the column block 52. The linkage rod 54 is formed by a long section on one side and a short section on the other side. The long section on the linkage rod 54 is The end corner intersecting with the short section is installed with a fixed block 58, the central axis of the end face of the fixed block 58 is connected with the linkage rod 54 by rotation, and the first rotating arm 55 is installed on one side of the short section of the linkage rod 54 in a non-fixed connection, and the end center of the first rotating arm 55 is installed with a rotating motor 57, and the first rotating arm 55 fixed on the central axis is driven by the rotating motor 57 to make a circular motion, the slider 51, the linkage rod 54 and the trigger rod 56 are non-fixedly connected, and a group of trigger rods 56 are welded on both sides of the first rotating arm 55, and one side of the first rotating arm 55 is welded The trigger rod 56 is in contact with the short section on one side of the linkage rod 54, the vertical rod 53 is welded on the other side of the slider 51, and the trigger rod 56 welded on the other side of the first rotating arm 55 is in contact with the vertical rod 53. The rotating motor 57 is started to drive the first rotating arm 55 with a fixed central axis sleeve to rotate in the vertical plane. At this time, the trigger rod 56 welded on one side of the first rotating arm 55 will drive the linkage rod 54 that is not fixedly connected to it to rotate in the vertical plane on the fixed block 58, and then the long section of the linkage rod 54 that is not fixedly connected to it will drive the column block 52 that is not fixedly connected to it to rotate in the vertical plane. The slider 51 moves horizontally on one side in the corresponding slide groove 4. When the trigger rod 56 welded on the other side of the first rotating arm 55 is acted upon by the rotational force, it will approach and contact the vertical rod 53, so that the slider 51 welded and fixed on the vertical rod 53 moves in the corresponding slide groove 4 in the opposite direction of the above-mentioned horizontal direction, thereby realizing that the cleaning brush 3 between the two column blocks 52 in the reciprocating motion mechanism 5 installed on the left slide rail 1 and the right slide rail 2 can remove debris on the coarse grid tooth rake while reciprocating on the upper horizontal surface of the coarse grid plate.

[0026] Among them, in order to realize convenient inspection and maintenance operations, in the present technical solution, the external structure of the slider 51 and the corresponding slide groove 4 are set to the same structure, and the structure is a trapezoidal structure that is narrow at the top and wide at the bottom. Through the slider 51 that is matched and slidably connected in the corresponding slide groove 4, when repairing or replacing the cleaning brush 3, it is only necessary to pull the slider 51 out of the corresponding slide groove 4.

[0027] Example 2

[0028] Based on Example 1, Figure 3As shown, a second rotating arm 59 is fixedly sleeved on the central axis of the rotating motor 57, and the second rotating arm 59 is a half structure of the first rotating arm 55. A single trigger rod 56 is welded on the side of the second rotating arm 59 away from the central axis. The rotating motor 57 is started to drive the second rotating arm 59 with a fixed sleeve on its central axis to rotate in the vertical plane. At this time, the single trigger rod 56 welded on one side of the second rotating arm 59 pushes the vertical rod 53 welded on one side of the slider 51 and the linkage rod 54 that is not fixedly connected to the column block 52 in turn under the action of the rotation force. When the trigger rod 56 comes into contact with and approaches the vertical rod 53 under the action of the rotation force, it drives the welding of the vertical rod 53 on the vertical rod 53 to rotate. The fixed slider 51 moves in the horizontal forward direction in the corresponding slide groove 4. When the trigger rod 56 contacts the linkage rod 54 under the driving of the rotational force, the slider 51 welded on the bottom of the column block 52 will move horizontally backward in the corresponding slide groove 4 through the long section of the linkage rod 54 contacting the non-fixed connected column block 52, thereby realizing the reciprocating movement of the slider 51 in the corresponding slide groove 4, and then realizing the cleaning brush 3 between the two column blocks 52 in the reciprocating motion mechanism 5 installed on the left slide rail 1 and the right slide rail 2 to remove debris on the coarse grid tooth rake while reciprocating on the upper horizontal surface of the coarse grid plate.

[0029] Among them, in order to solve the problem that the cleaning frequency of the original cleaning device cannot be adjusted, in the present technical solution, through the first rotating arm 55 in Example 1 and the second rotating arm 59 in Example 2, a one-step operation can be performed according to the situation of the incoming water pollutants, that is, replacing the first rotating arm 55 or the second rotating arm 59 to achieve the effect of appropriately adjusting the reciprocating frequency of the cleaning brush 3. The working principle is: the first rotating arm 55 has two trigger points per rotation, which can push the slider 51 to reciprocate twice, and the second rotating arm 59 has only one trigger point per rotation, which can push the slider 51 to reciprocate once.

[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
