[0015] The present invention provides a rotary grille sewage discharge device with an anti-blocking function, and the beneficial effects thereof are as follows:

[0016] 1. The rotary grille sewage discharge equipment with anti-blocking function, the first U-shaped plate moves upward to drive the first clamping plate to move upward, so that the first gear loses the limit of the first clamping plate, and also allows the first baffle to rotate counterclockwise. At this time, the first baffle and the second baffle can dump the garbage between the first baffle and the second baffle into the collection tank when the conveyor belt rotates, and then the garbage in the water is continuously salvaged as the conveyor belt circulates. This structure uses the conveyor belt to drive the first baffle and the second baffle to perform a circular motion, and then changes the angle between the first baffle and the second baffle, which can not only salvage the garbage in the water into the collection tank, but also use the change in the angle of the first baffle and the second baffle to prevent the garbage from blocking the first baffle and the second baffle.

[0017] 2. The rotary grille sewage discharge equipment with anti-clogging function, when the second protrusion completely passes through the first slide groove, the first gear is disengaged from the meshing force of the first rack, and the first U-shaped plate is driven by the rebound force of the first spring to move the first clamping plate downward, so that the first clamping plate is stuck inside the first gear, and at the same time, the second U-shaped plate is driven by the rebound force of the second spring to move the second clamping plate upward to limit the second gear, so that an angle can be formed between the second baffle and the first baffle to salvage garbage in the water, and multiple drainage grooves are opened inside the first baffle and the second baffle. At this time, water is discharged through the drainage grooves, and with the movement of the conveyor belt, the solid garbage in the water will move upward with the first baffle and the second baffle, and finally discharged into the collection tank.

[0018] 3. The rotary grille sewage discharge equipment with anti-blocking function, the second U-shaped plate is subjected to the pulling force of the second spring so that the second clamping plate on one side of the second U-shaped plate can be tightly clamped at the bottom of the second gear, so as to limit the second gear and prevent the angle of the second baffle from changing with the movement of the conveyor belt, which is not conducive to the salvage of garbage in the water. At the same time, the first U-shaped plate can be driven by the return force of the first spring to move the first clamping plate downward, and the downward movement of the first clamping plate can limit the first gear. At this time, the angle of the first baffle can be limited in the same way as the above principle, so that the position between the first baffle and the second baffle forms a certain angle, which is convenient for salvaging garbage in the water, and combined with the rotation of the conveyor belt, the salvage work can be repeated.

[0038] An embodiment of the present invention provides a rotary grille sewage discharge device with a clogging prevention function.

[0039] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14, including a support frame 1. Inside the support frame 1, there are multiple first baffles 2 and second baffles 3 for fishing pollutants in water. Inside the first baffle 2 and the second baffle 3, there is a rotating assembly for changing the fishing direction. On one side of the rotating assembly, there is a limiting assembly for limiting the fishing direction of the first baffle 2 and the second baffle 3. The rotating assembly includes multiple circular rods 4. Multiple circular rods 4 are respectively fixedly connected inside the first baffle 2, and another multiple circular rods 4 are respectively fixedly connected inside the second baffle 3. The limiting assembly further includes a second gear 301. The second gear 301 is fixedly connected to the outside of the circular rod 4. The outside of the circular rod 4 is rotatably connected to a second vertical plate 302. The bottom of the second vertical plate 302 is fixedly connected to a second telescopic rod 303 and a second spring 304. The second spring 304 is arranged outside the second telescopic rod 303. The bottom of the second telescopic rod 303 and the second spring 304 are fixedly connected to a second U-shaped plate 305. One side of the second U-shaped plate 305 is fixedly connected to a third convex block 306. Inside the second U-shaped plate 305, there is a second groove 308. Inside the support frame 1, there is a fourth convex block 307. The second U-shaped plate 305 is slidably connected to the fourth convex block 307 through the second groove 308. The top of the second gear 301 is meshed with a second rack 310. The second rack 310 is fixedly connected to the inside of the support frame 1. One side of the third convex block 306 and the fourth convex block 307 is an arc surface. One side of the second U-shaped plate 305 is fixedly connected to a second clamping plate 309. The second clamping plate 309 is clamped to the bottom of the second gear 301. By setting the fourth convex block 307, the third convex block 306 is subjected to the extrusion force of the fourth convex block 307. At this time, it can drive the second U-shaped plate 305 to move downward. The downward movement of the second U-shaped plate 305 drives the second clamping plate 309 to move downward, thereby causing the second gear 301 to lose the limit of the second clamping plate 309, so as to facilitate adjusting the angle of the second baffle 3. One side of the support frame 1 is fixedly connected to a motor 9. The output end of the motor 9 is fixedly connected to a rotating rod 10. The rotating rod 10 penetrates the support frame 1 and is rotatably connected to the support frame 1. The number of the rotating rods 10 is set to be multiple. The outside of the rotating rod 10 is fixedly connected to a roller 11. The roller 11 is arranged inside the support frame 1. There is a conveyor belt 12 outside the roller 11. By setting the conveyor belt 12, it is used to drive the first baffle 2 and the second baffle 3 to move together with the conveyor belt 12.

[0040] Multiple water leakage grooves 5 are respectively opened inside the first baffle 2 and the second baffle 3. Multiple support plates 6 are fixedly connected to the outside of the conveyor belt 12. The circular rod 4 penetrates the support plate 6 and is rotatably connected to the support plate 6. By setting the support plate 6, it is used to support the circular rod 4, so as to facilitate the circular rod 4 to run more stably. Both the first baffle 2 and the second baffle 3 are inclined. An included angle is formed between the first baffle 2 and the second baffle 3. By setting the first baffle 2 and the second baffle 3, not only can the garbage in the water be fished, but also the garbage can be prevented from blocking the first baffle 2 and the second baffle 3.

[0041] Specifically, when the grille sewage treatment equipment is in use, first install the equipment vertically in the water. Then start the motor 9, which drives the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the circular roller 11 to rotate. Through the cooperation of the circular roller 11 and the conveyor belt 12, the support plate 6 is driven to move along with the conveyor belt 12. When the support plate 6 moves, the circular rod 4 can be driven to move along with the support plate 6, so that the second vertical plate 302 outside the second baffle 3 moves along with the circular rod 4. The movement of the second vertical plate 302 drives the second telescopic rod 303 and the second spring 304 to move together. At this time, the second spring 304 is in a normal telescopic state. The second U-shaped plate 305 is pulled by the second spring 304, so that the second clamping plate 309 on one side of the second U-shaped plate 305 can tightly clamp the bottom of the second gear 301, thereby limiting the second gear 301 to prevent the angle of the second baffle 3 from changing when moving along with the conveyor belt 12, which is not conducive to salvaging the garbage in the water. At the same time, the first U-shaped plate 205 can drive the first clamping plate 207 to move downward under the action of the pulling force of the first spring 204. The downward movement of the first clamping plate 207 can limit the first gear 201. At this time, based on the same principle as above, the angle of the first baffle 2 can be limited, so that a certain included angle is formed between the positions of the first baffle 2 and the second baffle 3, which is convenient for salvaging the garbage in the water. Coupled with the rotation of the conveyor belt 12, the salvaging work can be carried out in a cycle.

[0042] Please refer to again Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14, the limiting component includes a first gear 201, the first gear 201 is fixedly connected to the outer side of the circular rod 4, a first vertical plate 202 is rotatably connected to the outer side of the circular rod 4, two first telescopic rods 203 and a first spring 204 are fixedly connected to the top of the first vertical plate 202, the first spring 204 is arranged on the outer side of the first telescopic rod 203, the top of the first telescopic rod 203 and the first spring 204 are fixedly connected to a first U-shaped plate 205, a first convex block 206 is fixedly connected to one side of the first U-shaped plate 205, a first clamping plate 207 is fixedly connected to one side of the first U-shaped plate 205, the first clamping plate 207 is clamped to the top of the first gear 201, a first chute 208 is opened inside the first U-shaped plate 205, a second convex block 209 is fixedly connected to the inside of the support frame 1, the first U-shaped plate 205 and the second convex block 209 are slidably connected through the first chute 208, a first rack 210 is meshed and connected to the bottom of the first gear 201, the first rack 210 is fixedly connected to the inside of the support frame 1, the sides of the first convex block 206 and the second convex block 209 are arc-shaped. By arranging the second convex block 209, when the first convex block 206 is subjected to the extrusion force of the second convex block 209, the first U-shaped plate 205 can move upward, thereby driving the first clamping plate 207 to move upward, so that the first gear 201 loses the limit of the first clamping plate 207, and thus the angle of the first baffle 2 is adjusted. The cross-sectional shapes of the first chute 208 and the second groove 308 are both rectangular, the cross-sectional width of the first chute 208 is greater than the cross-sectional width of the second convex block 209, and the cross-sectional width of the second groove 308 is greater than the cross-sectional width of the fourth convex block 307.

[0043] Specifically, when the second U-shaped plate 305 moves with the conveyor belt 12, the movement of the second U-shaped plate 305 drives the third protrusion 306 to move together, until the third protrusion 306 moves to the side of the fourth protrusion 307. At this time, the third protrusion 306 is squeezed by the fourth protrusion 307 and drives the third protrusion 306 to move downward. At this time, since the cross-sectional width of the second groove 308 is greater than the cross-sectional width of the fourth protrusion 307, the fourth protrusion 307 can pass through the second groove 308. When the second U-shaped plate 305 moves downward, it can drive the second clamping plate 309 to move downward. The downward movement of the second clamping plate 309 causes the second gear 301 to lose the second clamping plate 309. The fourth protrusion 307 is limited, at this time, while the fourth protrusion 307 slowly passes through the second groove 308, the second gear 301 is subjected to the meshing force of the second rack 310, and the second gear 301 can be driven to rotate, and the rotation of the second gear 301 drives the circular rod 4 to rotate, and the rotation of the circular rod 4 drives the second baffle 3 to rotate counterclockwise. At the same time, the first protrusion 206 is squeezed by the second protrusion 209, and the first protrusion 206 can be driven to move upward. When the first U-shaped plate 205 moves, the second protrusion 209 can pass through the inside of the first slide groove 208. When the first protrusion 206 moves upward, it can drive the first card plate 207 to move upward. The upward movement of the first card plate 207 can The first gear 201 loses its limit, and at the same time, the first gear 201 just moves to the top of the first rack 210, and the first gear 201 is rotated by the meshing force of the first rack 210. The rotation of the first gear 201 drives the circular rod 4 to rotate, and the rotation of the circular rod 4 drives the first baffle 2 to rotate clockwise. At this time, there is a 45-degree angle between the first baffle 2 and the second baffle 3. When the fourth protrusion 307 completely passes through the second groove 308, the second gear 301 just breaks away from the meshing force of the second rack 310. At the same time, when the second protrusion 209 completely passes through the first slide groove 208, the first gear 201 breaks away from the meshing force of the first rack 210. At this time, the first U The first clamping plate 207 is driven downward by the rebound force of the first spring 204 to make the first clamping plate 207 stuck inside the first gear 201. At the same time, the second U-shaped plate 305 is driven upward by the rebound force of the second spring 304 to limit the second gear 301. At this time, an angle can be formed between the second baffle plate 3 and the first baffle plate 2 to salvage garbage in the water. A plurality of drainage grooves 5 are provided inside the first baffle plate 2 and the second baffle plate 3. At this time, water is discharged through the drainage grooves 5. With the movement of the conveyor belt 12, the solid garbage in the water will move upward with the first baffle plate 2 and the second baffle plate 3, and finally be discharged into the collection tank.

[0044] Please refer again Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 ,Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 , a winding spring 401 is fixedly connected inside the circular rod 4, a support rod 402 is fixedly connected inside the winding spring 401, the support rod 402 is slidably connected inside the support frame 1. By providing the winding spring 401, it is convenient to drive the circular rod 4 to rotate and return to its original position, thereby facilitating the dumping of garbage and preventing the garbage from being blocked between the first baffle 2 and the second baffle 3. The limiting assembly further includes a fifth convex block 7 and a sixth convex block 8, both the fifth convex block 7 and the sixth convex block 8 are fixedly connected inside the support frame 1, and one side of both the fifth convex block 7 and the sixth convex block 8 is provided as an arc surface. By setting the fifth convex block 7 and the sixth convex block 8 as arc surfaces, the rotation directions of the first baffle 2 and the second baffle 3 are changed, and the garbage between the first baffle 2 and the second baffle 3 is dumped into the collection tank. A cavity is formed inside the support frame 1, the first rack 210 and the second rack 310 are both arranged inside the cavity, the fifth convex block 7, the sixth convex block 8, the fourth convex block 307 and the second convex block 209 are all arranged inside the cavity, and a collection tank for collecting the salvaged garbage is installed at the bottom of the support frame 1.

[0045] Specifically, when the first baffle 2 and the second baffle 3 move together with the conveyor belt 12, since the fifth bump 7 and the sixth bump 8 are also provided inside the cavity of the support frame 1, according to the same working principle as above, since one side of the fifth bump 7 and the sixth bump 8 is set as an arc surface, when the third bump 306 is subjected to the extrusion force of the fifth bump 7, at this time, the third bump 306 can move downward, thereby driving the second clamping plate 309 to move downward. At this time, the second gear 301 loses the limit of the second clamping plate 309. In the above working movement, since the rotation of the circular rod 4 causes the torsion spring 401 to generate torsion, now once the second gear 301 loses its limit, the circular rod 4 is subjected to the torsion of the torsion spring 401 to drive the circular rod 4 to reverse. The reverse rotation of the circular rod 4 drives the second baffle 3 to rotate clockwise, so that the second baffle 3 can fit on 16. In this state, similarly, when the first bump 206 is subjected to the extrusion force of the sixth bump 8, at this time, it can drive the first U-shaped plate 205 to move upward. The upward movement of the first U-shaped plate 205 drives the first clamping plate 207 to move upward, so that the first gear 201 loses the limit of the first clamping plate 207. Similarly, the first baffle 2 can rotate counterclockwise. At this time, when the first baffle 2 and the second baffle 3 rotate with the conveyor belt 12, the garbage between the first baffle 2 and the second baffle 3 can be poured into the collection tank, and then continuously cycle to fish the garbage in the water with the conveyor belt 12. This structure uses the conveyor belt 12 to drive the first baffle 2 and the second baffle 3 to perform a cyclic movement, and at the same time, by changing the included angle between the first baffle 2 and the second baffle 3, not only can the garbage in the water be fished into the collection tank, but also the change in the angles of the first baffle 2 and the second baffle 3 is used to prevent the garbage from blocking the first baffle 2 and the second baffle 3.

[0046] Working principle: The second gear 301 loses the limit of the second clamping plate 309. In the above working movement, since the rotation of the circular rod 4 causes the torsion spring 401 to generate torsion, now once the second gear 301 loses its limit, the circular rod 4 is subjected to the torsion of the torsion spring 401 to drive the circular rod 4 to reverse. The reverse rotation of the circular rod 4 drives the second baffle 3 to rotate clockwise, so that the second baffle 3 can fit on 16. In this state, similarly, when the first bump 206 is subjected to the extrusion force of the sixth bump 8, at this time, it can drive the first U-shaped plate 205 to move upward. The upward movement of the first U-shaped plate 205 drives the first clamping plate 207 to move upward, so that the first gear 201 loses the limit of the first clamping plate 207.
