A sewage outlet 11 is provided at the lower end of the water storage tank 10. A baffle 12 is hinged on the sewage outlet 11. The baffle 12 is always hinged along the The force of the axial swing blocks the sewage outlet 11. When the water storage in the water storage tank 10 reaches a certain volume, the baffle 12 can continue to open the sewage outlet 11 for a period of time and then close again.

A boss is fixed at the lower end of the outer edge surface of the inner cylinder 4, and a compression spring is provided between the boss and the water retaining plate 8. The compression spring always gives the water retaining plate 8 an upward thrust.

The left end of the baffle 12 is hinged to the left end of the sewage outlet 11, and a weight 13 is fixed to the left end of the baffle 12 on the left side of the hinge axis. The weight 13 forces the right side of the baffle 12 to always receive an upward force to close the sewage outlet 11.

In order to extend the opening time of the baffle 12, the upper end surface of the baffle 12 is provided with a chute 14 in the left and right directions on the inner side of the sewage outlet 11. The chute 14 is provided with a slider 15 that can slide left and right. The slider 15 With a certain gravity, when the baffle 12 opens the sewage outlet 11, the slider 15 can slide to the right, and when the baffle 12 closes the sewage outlet 11, the slider 15 can reset to the left.

The lower end surface of the sewage outlet 11 is a slope with a lower left and a higher right. When the baffle 12 closes the sewage outlet 11, it is inclined with a low left and a high right. Threading rings 16 are fixed on the left and right sides of the chute 14, and the left and right ends of the slider 15 are fixed. A drawstring 17 is fixed respectively. The right drawstring 17 passes through the right threading ring 16 and is fixedly connected to the inner edge surface of the sewage outlet 11. The left drawstring 17 passes through the left threading ring 16 and is fixedly connected upward to the water baffle 8. , when the baffle 12 closes the sewage outlet 11, the slider 15 is placed at the leftmost end of the chute 14 under the action of its own gravity. At this time, the two pull ropes 17 are in a straightened state. When the baffle 12 opens the sewage outlet 11 , the slider 15 can be pulled by the right side pull rope 17 and slide to the right along the chute 14. At the same time, the slider 14 pulls the water baffle 8 downward through the left side pull rope 17, so that the upper end surface of the water baffle 8 is lower than the annular shape. The lower end surface of plate 9 and the upper end surface of annular filter plate 6 are lower than the lower end surface of tube sheet 3.

The sewage outlet 11 is a rectangular opening, and a scraper 19 placed vertically front and back is fixed on the slider 15.

When the baffle 12 closes the sewage outlet 11, the scraper 19 It can be placed inside the sewage outlet 11.

A filter screen is provided inside the drain outlet 7 .

The lower end face of the drainage outlet 7 is not lower than the lower end face of the tube plate 3 .

A horizontal horizontal tube 18 is fixed at the lower end of the inner cylinder 4 . The horizontal tube 18 penetrates the outer cylinder 1 and is fixedly connected to the outer cylinder 1 .

It is worth mentioning that in order to prevent the water baffle 8 from shaking up and down when working in heavy rainfall, the opening area of the drainage outlet 7 should be set to be no larger than the total opening area of the water inlet 4.

In order to facilitate sedimentation and collection at the sewage outlet 11, the lower end surface of the water storage tank 10 is a funnel-shaped conical surface.

When the present invention is in use, both the outer cylinder 1 and the water storage tank 10 are pre-buried underground, so that the upper end surface of the outer cylinder 1 is flush with the ground, and the horizontal pipe 18 is connected to the municipal drainage pipe, which can be installed below the sewage outlet 11 Cloth bags or receiving boxes for collecting garbage and sludge to facilitate centralized treatment of garbage and sludge;

In rainy weather, rainwater passes through the water inlet 2 and is filtered by the annular filter plate 6 and then enters the cavity of the outer cylinder 1. Then it falls on the water baffle 8 and continues to fall downward through the gap between the water baffle 8 and the annular plate 9. The water storage tank 10 below realizes the collection and precipitation of rainwater; when the duration of rainfall or the amount of rainfall gradually increases, the amount of water entering the cavity of the outer cylinder 1 through the water inlet 2 is greater than the amount of water entering the cavity of the outer cylinder 1 through the water retaining plate 8 and the annular plate 9 The discharge amount is downward at intervals, and the rainwater gathers above the baffle 8, causing the gravity to continuously increase, and finally overcomes the elastic force of the compression spring to push the baffle 8, the sleeve 5 and the annular filter plate 6 to move synchronously, and the sleeve 5 moves to the After moving downward, the drain outlet 7 is exposed, and the rainwater that cannot be discharged from the gap between the water retaining plate 8 and the annular plate 9 enters the inner cylinder 4 through the drain outlet 7, and is then discharged into the municipal drainage pipe through the horizontal pipe 18. Since the annular plate 9 The inner diameter gradually decreases from top to bottom. Once the water baffle 8 moves downward, the water baffle 8 will not reset upward before the rainfall decreases; because the rainwater in the early stage of rain will evenly distribute the mud or dust on the municipal road. The water is washed away and discharged into the water storage tank 10, so the sediment content of subsequent rainwater discharged into the municipal pipeline through the drainage outlet 7 is greatly reduced, which greatly reduces the risk of municipal pipeline blockage. Rainwater is subject to sedimentation treatment;

When the rainwater in the water storage tank 10 is accumulated to an amount that can overcome the gravity of the weight 13, the right end of the baffle 12 swings downward along the hinge axis under the action of the gravity of the rainwater, gradually opening the sewage outlet, and at the same time, the slider 15 pulls the rope on the right side. 17 slides to the right along the chute 14, and the slider 15 drives the scraper 19 to move synchronously to the right, scraping all the sediment and garbage deposited at the sewage outlet 11 to the right and out of the sewage outlet 11. At the same time, the slider 15 Use the left pull rope 17 to overcome the compression spring force and pull down the water baffle 8, so that the upper end surface of the water baffle 8 is lower than the lower end surface of the annular plate 9, and the upper end surface of the annular filter plate 6 is lower than the lower end surface of the tube plate 3, such as As shown in Figure 5, the large particles of garbage deposited on the upper sides of the annular filter plate 6 and the water baffle 8 can be discharged downward into the water storage tank 10 under the erosion of rainwater, and can be released on the left side after the slider 15 is reset to the left. Pull the rope 17 to reset the annular filter plate 6 upward to the inside of the tube plate 3 to continue filtering rainwater, and to reset the water baffle 8 upward to the inside of the annular plate 6 to continue to block water;

Since the sewage outlet 11 is opened, the rainwater in the water storage tank 10 will be discharged together with the sedimentation, and the gravity exerted on the baffle 12 will be reduced. However, since the slider 15 itself has a certain gravity, and it will always move along the baffle 12 during the clocking process. The chute 14 moves to the right, and the downward gravity arm exerted by the slider 15 on the baffle 12 continues to become longer and the force also continues to increase, which can compensate for the reduction in the downward thrust of the baffle 12 caused by the reduction in the weight of rainwater. Small, to prevent the baffle 12 from resetting upward in advance and closing the sewage outlet 11. Until the slider 15 moves to the right to the right end of the chute 14, the force arm no longer increases, and the rainwater in the water storage tank 10 continues to decrease, which will cause the weight 13 to Re-drive the baffle 12 to swing upward along the hinge axis to close the sewage outlet 11. Since the lower end surface of the sewage outlet 11 is a slope with lower left and higher right, the baffle 12 is also in a state of low left and high right after reset. The slider 15 above it It can be reset to the left side of the chute 14 under the action of its own gravity.

The invention uses the gravity of rainwater instead of electronic control components as the power source, greatly improves the overall practicality of the device, reduces production and use costs, and controls the amount of rainfall separated by the water barrier 8 and the annular plate 9 through the water barrier 8, making the rain weather better. In the first half of the period, rainwater with a large sediment content can be preferentially entered into the water storage tank on the lower side through the baffle plate 8 and the annular plate 9 for collection and precipitation. Subsequent rainwater with a small sediment content can be gradually blocked by the baffle plate 8 and drained through Port 7 is discharged into the municipal pipeline, which greatly reduces the risk of municipal pipeline blockage; the weight 13 is used to control the switch of the sewage outlet 11, and the slider 15 is used to change the force arm of the baffle 12 to extend the opening time of the baffle 12, so that the water storage tank After the water output in the water storage tank 10 meets a certain gravity, the sewage outlet 11 is automatically opened for a certain period of time, so that all the sediment at the bottom of the water storage tank 10 is discharged, improving the water storage quality in the water storage tank 10, making it easier to fetch and use water later, and reducing the difficulty of subsequent cleaning of the water storage tank.
