Detailed implementation mode

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Refer Figures 1 to 6 As shown, a water volume regulating device includes an outer frame 1, a water baffle 2 is welded on the outer frame 1, and the outer frame 1 and the water baffle 2 are fixed to the water channel. A plurality of water passing holes 203 are formed on the water baffle 2 for the passage of sewage. A first through hole 202 is formed on the water baffle 2, and a water regulating plate 3 matching with a plurality of water passing holes 203 is arranged in the outer frame 1. A second through hole 301 is formed on the water regulating plate 3, and one end of an adjusting screw 6 passes through the first through hole 202 and is threadedly connected in the second through hole 301. The upper end of the adjusting screw 6 is a cuboid, and the horizontal projection of the cuboid can cover the horizontal projection of the second through hole 301. In this way, the adjusting screw 6 cannot vertically pass through the second through hole 301, which is convenient for the installation of the adjusting screw 6. On the basis of keeping the adjusting screw 6 stationary in the vertical direction, the adjusting screw 6 is rotated, thereby driving the water regulating plate 3 to move up and down. By adjusting the area of the water passing holes 203 covered by the water regulating plate 3, the purpose of finally adjusting the water passing volume is achieved. Specifically, in order to improve the connection strength between the water regulating plate 3 and the adjusting screw 6, a hexagonal nut 13 matching with the adjusting screw 6 can be welded on the water regulating plate 3, and the hexagonal nut 13 is concentric with the second through hole 301. At the same time, in order to improve the connection strength between the hexagonal nut 13 and the water regulating plate 3, a flange 14 is welded on the water regulating plate 3. A sixth through hole 141 is formed on the flange 14, and the hexagonal nut 13 is welded in the sixth through hole 141 while being welded to the water regulating plate 3.

[0027] Refer Figure 5 、 Figure 6As shown, a limiting groove 201 is provided on the water retaining plate 2, and a third through hole 302 is provided on the water regulating plate 3. Fastening bolts 11 are inserted into the limiting groove 201 and the third through hole 302, and a fastening lock nut 5 is threadedly connected to the fastening bolt 11, so that the water regulating plate 3 can be limited in the vertical direction so that it can only move up and down along the limiting groove 201. To a certain extent, the displacement quality of the water regulating plate 3 in the vertical direction can be improved, which is convenient for adjusting the water flow rate.

[0028] Ginseng Figure 3 As shown, a hand wheel 7 is sleeved on the adjusting screw 6, and a fourth through hole 701 matching the upper end of the adjusting screw 6 is provided on the hand wheel 7, so that the adjusting screw 6 can be rotated by the hand wheel 7. In addition, a bearing 12 is sleeved on the adjusting screw 6, and the bearing 12 is directly arranged between the water regulating plate 3 and the hand wheel 7, so as to smoothly rotate the adjusting screw 6. Specifically, the bearing 12 can be a thrust ball bearing, which can withstand axial loads. The thrust ball bearing is divided into a seat ring and a shaft ring. The shaft ring should be tightly matched with the adjusting screw 6, and the seat ring should be in good contact with the lower surface of the hand wheel 7 and the upper surface of the water regulating plate 3.

[0029] Ginseng Figure 4 , Figure 7 As shown, a second gripping portion 8 is welded on the hand wheel 7 to facilitate better rotation of the hand wheel 7. A cross bar 9 is mounted on the second gripping portion 8, and a fifth through hole 901 corresponding to the second gripping portion 8 is provided on the cross bar 9, so that the second gripping portion 8 can be rotated by the cross bar 9 to complete the synchronous rotation of the hand wheel 7, so that the displacements of the two ends of the water regulating plate 3 in the vertical direction are the same, so as to ensure the steady rise or fall of the water regulating plate 3, so that the connection quality of the adjusting screws 6 and the hexagonal nuts 13 at the two places is good, so as not to cause large wear and tear, and increase their service life.

[0030] The second gripping portion 8 is welded with a limiting block 801 to facilitate the positioning of the cross bar 9, so as to prevent the cross bar 9 from contacting the hand wheel 7 and reduce the friction generated when the cross bar 9 rotates, so that the cross bar 9 can rotate more smoothly and with less effort. In addition, the limiting block 801 can also increase the strength and stability of the second gripping portion 8. In order to facilitate the gripping of the cross bar 9, fastening bolts 11 are welded at both ends of the cross bar 9.

[0031] Ginseng Figure 1 As shown, in order to increase the practicality of the water volume regulating device, a storage rack 4 is welded on the water regulating plate 3. When the hand wheel 7 is to be rotated alone, the cross bar 9 can be disassembled to complete the adjustment of the two sides of the water regulating plate 3, and the cross bar 9 can be placed on the storage rack 4. Specifically, the length of the cross bar 9 is less than the length of the hand wheel 7, and the height of the cross bar 9 is less than the width of the storage rack 4, so that the cross bar 9 can be placed on the storage rack 4.

[0032] When using it specifically, refer to Figure 1As shown, the two second grasping parts 8 can be rotated respectively to complete the displacement of the water regulating plate 3 in the vertical direction. When the second grasping part 8 is rotated clockwise, the water regulating plate 3 rises and the water passing amount increases; when the second grasping part 8 is rotated counterclockwise, the water regulating plate 3 descends and the water passing amount decreases. Also, as Figure 7 shown, grasp the handle rod 10 and rotate the cross bar 9 to drive the second grasping part 8 to rotate, thereby driving the vertical displacement of the water regulating plate 3 to adjust the water passing amount. Similarly, when the second grasping part 8 is rotated clockwise, the water regulating plate 3 rises and the water passing amount increases; when the second grasping part 8 is rotated counterclockwise, the water regulating plate 3 descends and the water passing amount decreases.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
