[0026] See also Figure 1 and Figure 2 The embodiment of the present invention provides a grate anti-blocking device, including a grate 1, which is covered on the top of a drainage well 2 and is used to filter garbage. The grate 1 has a water drop hole 3, and rainwater or other liquids above the grate 1 flow into the drainage well 2 through the water drop hole 3, and garbage above the grate 1, such as plastic bags, leaves, etc., remain above the grate 1 to form a blockage. The grate anti-blocking device also includes a driving mechanism and a cleaning component. The driving mechanism provides power for the cleaning component. The cleaning component is installed in the drainage well 2 through a first rotating shaft 4. The first rotating shaft 4 is arranged horizontally so that the cleaning component can rotate around the first rotating shaft 4. The cleaning component has a plurality of rake teeth 5. The rake teeth 5 are used to clean the blockage. The driving device drives the cleaning component to rotate around the first rotating shaft 4 so that the rake teeth 5 extend out of the water drop hole 3 and move back and forth. The rake teeth 5 rotate back and forth within a certain angle range with the first rotating shaft 4 as the center and the distance from the rake teeth 5 to the first rotating shaft 4 as the radius, and extend out of the water drop hole 3 within a certain rotation range to lift the blockage, and move the rake teeth back and forth to open the blockage above the grate 1. The blockage can be washed away by rainwater to prevent the water drop hole 3 of the grate 1 from being blocked.

[0027] When it rains, the driving device drives the cleaning component to rotate around the first rotating shaft 4. When the cleaning component rotates, the rake teeth 5 can be extended out of the water hole 3 and moved back and forth in the water hole 3 to remove the blockage above the grate 1, and the blockage is washed away from the top of the grate 1 by rainwater to prevent the water hole 3 of the grate 1 from being blocked, so that the rainwater can flow smoothly into the drainage well 2 to ensure the normal operation of road traffic. It can be understood that the number of cleaning components can be set to one or more according to the actual distribution of the water holes 3 and the rotation range of the cleaning components to ensure that the blockage above the water holes 3 can be cleaned in time.

[0028] The driving mechanism can be a motor, a crank slider mechanism, a lever structure, etc. Figure 2 and Figure 4In some embodiments, the driving mechanism includes a first water bucket 6 and a second water bucket 7 symmetrically distributed on both sides of the first rotating shaft 4. The first water bucket 6 and the second water bucket 7 are connected to the first rotating shaft 4 through a first transverse connecting component 8 to form a lever structure. The lever structure swings up and down to drive the cleaning component to rotate forward and reverse around the first rotating shaft 4, so that the rake teeth 5 can move back and forth in the water drop hole 3 within a certain rotation range to remove the garbage above the water drop hole 3. Specifically, the first water bucket 6 switches between the first position and the second position, the first water bucket 6 stores rainwater in the first position, and the first water bucket 6 releases rainwater in the second position, and the first position is higher than the second position. The second water bucket 7 switches between the third position and the fourth position, the second water bucket 7 stores rainwater in the third position, and the second water bucket 7 releases rainwater in the fourth position, and the third position is higher than the fourth position. That is, when the first water bucket 6 is located in the first position to store rainwater, the second water bucket 7 is located in the fourth position to release rainwater, and when the first water bucket 6 is located in the second position to release rainwater, the second water bucket 7 is located in the third position to store rainwater. The first water bucket 6 and the second water bucket 7 both achieve changes in weight by continuously storing and releasing rainwater, thereby switching between different height positions to achieve a lever effect. No other power drive is required to drive the cleaning component to rotate, and automatically remove the garbage above the drain hole 3, which is energy-saving and environmentally friendly, and can accelerate the speed of clearing blockages accordingly with the falling intensity of rainwater, and is highly practical.

[0029] The driving mechanism can be directly arranged below the drainage well 2, or can be arranged on the side of the drainage well 2. Figure 1 and Figure 3 In some embodiments, a water bucket groove 9 is provided on the side of the drainage well 2, and the driving mechanism is located in the water bucket groove 9, which can avoid direct contact between the driving mechanism and rainwater, thereby preventing rainwater from scouring the driving mechanism on a large scale and causing damage. It also includes a water collecting component 10, which is used to collect rainwater. The water collecting component 10 is located below the grate 1 and is respectively connected to the first water bucket 6 and the second water bucket 7, so that the rainwater in the water collecting component 10 can flow into the first water bucket 6 and the second water bucket 7 respectively. The water collecting component 10 provides rainwater to the first water bucket 6 and the second water bucket 7, so that the driving mechanism has the function of swinging up and down, thereby driving the cleaning component to rotate.

[0030] See also Figure 3 In some embodiments, the water bucket 9 is provided with a drainage channel 11 connected to the drainage well 2, so that the rainwater released from the first water bucket 6 and the second water bucket 7 flows into the drainage well 2 and is discharged outward, thereby achieving a water-free or low-water environment inside the water bucket 9 and ensuring that the driving mechanism can work normally.

[0031] See also Figure 2 and Figure 4In some embodiments, a second rotating shaft 12 and a first floating member 13 connected to the second rotating shaft 12 are provided in the first water bucket 6, and a first push rod 14 is provided above the first floating member 13, and the first floating member 13 can rotate around the second rotating shaft 12 to rise or fall. When the first water bucket 6 is located at the first position to store rainwater, the rainwater stored in the first water bucket 6 to a certain height can drive the first floating member 13 to rotate around the second rotating shaft 12 and rise, and the first floating member 13 can lift up the first push rod 14 when it rises. The other end of the first push rod 14 is connected to a first rotating rod 15, and the first rotating rod 15 is connected to the third rotating shaft 16 and rotates around the third rotating shaft 16, and the other end of the first rotating rod 15 contacts the end of the first L-shaped transition rod 17. A first support rod 18 is provided above the first water bucket 6, and the first support rod 18 extends to above the other end of the first L-shaped transition rod 17. When the first rotating rod 15 rotates, it can drive the first L-shaped transition rod 17 to move away from the first support rod 18 in the lateral direction of the first L-shaped transition rod 17. After the first support rod 18 loses the support of the first L-shaped transition rod 17, the first water bucket 6 can fall back to the second position from the first position. At this time, under the action of the lever structure, the second water bucket 7 can rise back to the third position from the fourth position.

[0032] See also Figure 2 , a fourth rotating shaft 19 and a second floating member 20 connected to the fourth rotating shaft 19 are provided in the second water bucket 7, a second top rod 21 is provided above the second floating member 20, and the second floating member 20 can rotate around the fourth rotating shaft 19 to rise or fall. When the second water bucket 7 is located at the third position to store rainwater, the rainwater stored in the second water bucket 7 to a certain height can drive the second floating member 20 to rotate around the fourth rotating shaft 19 and rise, and the second floating member 20 can lift up the second top rod 21 when it rises. The other end of the second top rod 21 is connected to a second rotating rod 22, the second rotating rod 22 is connected to the fifth rotating shaft 23 and rotates around the fifth rotating shaft 23, and the other end of the second rotating rod 22 contacts the end of the second L-shaped transition rod 24. A second support rod 25 is provided above the second water bucket 7, and the second support rod 25 extends to the top of the other end of the second L-shaped transition rod 24. When the second rotating rod 22 rotates, it can drive the second L-shaped transition rod 24 to move away from the second support rod 25 along the lateral direction of the second L-shaped transition rod 24. After the second support rod 25 loses the support of the second L-shaped transition rod 24, the second water bucket 7 can fall back to the fourth position from the third position. At this time, under the action of the lever structure, the first water bucket 6 can rise back to the first position from the second position. In this way, the driving mechanism can automatically work under the action of rainwater, which is energy-saving, environmentally friendly and resource-saving. Among them, when the first water bucket 6 or the second water bucket 7 releases rainwater, the first top rod 14 and the second top rod 21 can return to their original positions under the action of gravity. In this way, the first top rod 14 or the second top rod 21 can continue to drive the first rotating rod 15 or the second top rod 21 to rotate when the water level reaches a certain height.

[0033] See also Figure 2and Figure 4 In some embodiments, the first L-shaped transition rod 17 is connected to the first elastic component 26, and a first guide component 27 for guiding the first support rod 18 to move to the top of the first L-shaped transition rod 17 is provided above the first water bucket 6, so that when the first water bucket 6 rises from the second position to the first position, it can return to the top of the first L-shaped transition rod 17 under the guidance of the first guide component 27. Through the provision of the first elastic component 26, the first L-shaped transition rod 17 automatically returns to the original position in contact with the first support rod 18, thereby supporting the first L-shaped transition rod 17.

[0034] See also Figure 2 The second L-shaped transition rod 24 is connected to the second elastic component 28, and a second guide component 29 for guiding the second support rod 25 to move to the top of the second L-shaped transition rod 24 is provided above the second water bucket 7, so that when the second water bucket 7 rises from the fourth position to the third position, it can return to the top of the second L-shaped transition rod 24 under the guidance of the second guide component 29. Through the provision of the second elastic component 28, the second L-shaped transition rod 24 automatically returns to the original position in contact with the first support rod 18, thereby supporting the second L-shaped transition rod 24.

[0035] Specifically, one end of the first guide member 27 can be connected to the end of the first L-shaped transition rod 17 separately, and the other end of the first guide member 27 is connected to the rotation spring; the end of the first guide member 27 can also be fixedly connected to the first L-shaped transition rod 17. Similarly, one end of the second guide member 29 can be connected to the end of the second L-shaped transition rod 24 separately, and the other end of the second guide member 29 is connected to the rotation spring; the end of the second guide member 29 can also be fixedly connected to the second L-shaped transition rod 24.

[0036] See also Figure 2 and Figure 4In some embodiments, a first water outlet 30 and a first gate mechanism that slides up and down along the side wall of the first water bucket 6 are provided on the side wall of the first water bucket 6, and a second water outlet 31 and a second gate mechanism that slides up and down along the side wall of the second water bucket 7 are provided on the side wall of the second water bucket 7. When the first water bucket 6 is in the first position, the first gate mechanism covers the first water outlet 30, so that the first water bucket 6 can store rainwater; when the first water bucket 6 is in the second position, the first gate mechanism slides upward relative to the side wall of the first water bucket 6, and the first gate mechanism opens the first water outlet 30, so that the rainwater in the first water bucket 6 can flow out from the first water outlet 30; when the second water bucket 7 is in the third position, the second gate mechanism covers the second water outlet 31, so that the second water bucket 7 can store rainwater; when the second water bucket 7 is in the third position, the second gate mechanism slides upward relative to the side wall of the second water bucket 7, and the second gate mechanism opens the second water outlet 31, so that the rainwater in the second water bucket 7 can flow out from the second water outlet 31.

[0037] By setting the first gate mechanism and the second gate mechanism, the weight of the first water bucket 6 and the second water bucket 7 is increased or decreased accordingly, so that the first water bucket 6 and the second water bucket 7 can be switched between different positions, so that the driving mechanism swings up and down, thereby driving the cleaning component to rotate around the first rotating shaft 4 to achieve the cleaning function. It can be understood that the first gate mechanism can be set in the first water bucket 6, that is, located on the inner side of the side wall of the first water bucket 6, or can be set outside the first water bucket 6, that is, located on the outer side of the side wall of the first water bucket 6. Similarly, the second gate mechanism can be set in the second water bucket 7, that is, located on the inner side of the side wall of the second water bucket 7, or can be set outside the second water bucket 7, that is, located on the outer side of the side wall of the second bucket.

[0038] See also Figure 2 In some embodiments, the water bucket 9 is provided with a first stopper 32 on the outer side of the side wall of the first water bucket 6, see Figure 4 and Figure 5 The first gate mechanism includes a first gate plate 33 shielding the first water outlet 30 and a first gate rod 34 connected to the first gate plate 33, see Figure 2 , the top of the first gate rod 34 extends horizontally to the top of the first stopper 32. When the first water bucket 6 switches from the first position to the position close to the second position, the first stopper 32 abuts against the first gate plate 33, limiting the first gate plate 33 so that the first gate plate 33 cannot continue to slide downward with the first water bucket 6, that is, the first gate plate 33 slides upward relative to the first water outlet 30. When the first water bucket 6 is in the second position, the first stopper 32 continues to abut against the first gate plate 33, and the first gate plate 33 opens the first water outlet 30, so that the rainwater in the first water bucket 6 flows out from the first water outlet 30. When the first water bucket 6 switches from the second position back to the first position, the first gate mechanism can cover the first water outlet 30 under the action of gravity and start to collect rainwater.

[0039] See also Figure 2 , the water bucket 9 is provided with a second stopper 35 on the outer side of the side wall of the second water bucket 7, and the second gate mechanism includes a second gate plate that shields the second water outlet 31 and a second gate rod connected to the second gate plate, and the top of the second gate rod extends horizontally to the top of the second stopper 35. In the process of the second water bucket 7 switching from the third position to the position close to the fourth position, the second stopper 35 abuts against the second gate plate, and limits the second gate plate, so that the second gate plate cannot continue to slide downward with the second water bucket 7, that is, the second gate plate slides upward relative to the second water outlet 31. When the second water bucket 7 is in the third position, the second stopper 35 continues to abut against the second gate plate, and the second gate plate opens the second water outlet 31, so that the rainwater in the second water bucket 7 flows out from the second water outlet 31. When the second water bucket 7 switches from the fourth position back to the third position, the second gate mechanism can shield the second water outlet 31 under the action of gravity and start to collect rainwater.

[0040] Specifically, a first sliding channel 36 for the first gate rod 34 to slide up and down is provided on the side wall of the first water bucket 6. The first sliding channel 36 can be set on the outer side of the side wall of the first water bucket 6, or on the inner side of the side wall of the first bucket. Similarly, a second sliding channel for the second gate rod to slide up and down is provided on the side wall of the second water bucket 7. The second sliding channel can be set on the outer side of the side wall of the second water bucket 7, or on the inner side of the side wall of the second bucket.

[0041] When the first water bucket 6 is switched to the second position or the second water bucket 7 is switched to the fourth position, the first water bucket 6 or the second water bucket 7 needs to be restricted from continuing to move downward. Figure 2 , Figure 4 and Figure 5 In some embodiments, the first gate rod 34 is provided with a third stopper 37 for resisting the top of the first water bucket 6 to limit the stroke of the first water bucket 6. When the first water bucket 6 is switched to the second position, the first gate rod 34 restricts the first water bucket 6 from continuing to move downward. The second gate rod is provided with a fourth stopper for resisting the top of the second water bucket 7 to restrict the stroke of the second water bucket 7. When the second water bucket 7 is switched to the fourth position, the second gate rod restricts the second water bucket 7 from continuing to move downward, so that the driving mechanism swings within a certain angle range, ensuring that the rake teeth 5 are not interfered with by other structures when they are moved back and forth within a certain angle range. It is understandable that the first water bucket 6 and the second water bucket 7 can also be limited by setting a blocking member in the water bucket groove 9.

[0042] See also Figure 2 and Figure 4In some embodiments, a first roller 38 is provided at the top of the first support rod 18, and a second roller 39 matching the first roller 38 is provided at the end of the first L-shaped transition rod 17. The first support rod 18 can be transitioned to the top of the first L-shaped transition rod 17 by the arrangement of the first roller 38 and the second roller 39, which is conducive to ensuring the stability of the first water bucket 6 when switching to the first position. A third roller is provided at the top of the second support rod 25, and a fourth roller matching the third roller is provided at the end of the second L-shaped transition rod 24. The second support rod 25 can be transitioned to the top of the second L-shaped transition rod 24 by the arrangement of the third roller and the fourth roller, which is conducive to ensuring the stability of the second water bucket 7 when switching to the third position.
