As shown in fig. 1, the drainage system of the present invention is assembled in its entirety, and is installed under the ground. The drainage system of fig. 1 includes a housing 1 and an internal drainage device. The top surface of the outer cover 1 is provided with a ground drainage grate 2, and the ground drainage grate 2 is flush with the ground and is used for leaking ground water and garbage to drain into a sewer.
Fig. 2 is a schematic view of the drainage system of fig. 1, with the cover 1 removed. The internal drainage device comprises a lower layer drainage grate positioned right below the ground drainage grate 2, wherein the two layers of drainage grate are arranged at close distance, and the interval is 1-10 cm for effective shearing movement. The lower layer drainage grate is of a strip-shaped U-shaped groove structure, a cylindrical drainage grate 3 and a strip-shaped rectangular drainage grate 4 are fixedly arranged in the strip-shaped U-shaped groove at intervals, and a protruding sliding block is further arranged on the outer side face of the lower layer drainage grate. The cylindrical drainage grate 3 and the long rectangular drainage grate 4 can be integrally driven to move so as to cut and shear solid garbage falling from the ground drainage grate 2, and garbage accumulation entering a sewer is reduced.
Fig. 3 is an enlarged view of the transmission mechanism of the cylindrical drain grate 3 and the elongated rectangular drain grate 4 of fig. 2. The transmission mechanism for the cylindrical drainage grate 3 and the rectangular drainage grate 4 to move back and forth comprises a crank 5, a disc 6 and an outer disc 7. The disc 6 fits into a circular groove formed in the outer disc 7, and the disc 6 can be driven by a power mechanism to rotate in the circular groove. An inner convex cylinder 61 is arranged on the upper surface of the disc 6 near the edge, an outer convex cylinder 71 is arranged on the upper surface of the outer disc 7, which is not positioned in the circular groove, a sliding groove 72 is arranged on the outer side surface of the outer disc 7, and the outer convex cylinder 71 is arranged on one side far away from the sliding groove 72. The sliding block of the lower layer drainage grate is embedded into the sliding groove 72, and the sliding block can slide in the sliding groove 72 under the action of external force.
A tail end convex cylinder 31 is arranged in the U-shaped groove of the lower layer drainage grate and between the cylindrical drainage grate 3 and the rectangular drainage grate 4. The crank 5 is of a strip-shaped structure and is horizontally arranged, and the crank 5 is provided with three sections of longitudinally penetrated holes, wherein the three sections of holes are sequentially a first section of hole, a second section of hole and a third section of hole from one end to the other end. The first section of hole is cylindrical, the diameter of the first section of hole is consistent with that of the outer convex cylinder 71, and the outer convex cylinder 71 penetrates into the first section of hole upwards; the second section of hole is strip-shaped, the width of the second section of hole is the same as the diameter of the inner convex cylinder 61, and the inner convex cylinder 61 penetrates into the second section of hole upwards and can slide in the strip-shaped hole; the third section of hole is an open-ended strip-shaped hole, the width of which is the same as the diameter of the end convex cylinder 31, and the end convex cylinder 31 penetrates upwards into the open-ended strip-shaped hole.
The disc 6 is driven by a power mechanism connected with the lower end of the disc 6 to rotate, the inner convex cylinder 61 moves circularly along with the disc, the circular motion of the inner convex cylinder 61 drives the crank 5 to rotate in a fan shape by taking the outer convex cylinder 71 as an approximate circle center, the tail convex cylinder 31 is driven to move back and forth in a third section hole of the crank 5, and the moving track of the tail end of the crank 5 becomes an arc of the fan-shaped rotating pattern. Since the sliding block of the lower layer drainage grate is limited in the sliding groove 72, the end convex cylinder 31 moves linearly back and forth relative to the sliding groove 72, and accordingly, the cylindrical drainage grate 3 and the long rectangular drainage grate 4 move linearly back and forth along the sliding groove 72. Therefore, the cylindrical drainage grate 3 and the strip rectangular drainage grate 4 do back and forth linear motion relative to the fixed ground drainage grate 2, and the grid lines of the cylindrical drainage grate 3 and the strip rectangular drainage grate 4 are perpendicular to the grid lines of the ground drainage grate 2, so that the back and forth motion can effectively cut hard and brittle matters such as branches, and the problem that the water outlet cannot be normally drained due to accumulation and blockage of sundries such as dead leaves and dead branches is effectively avoided. The rectangular drainage grate 4 has sharp edges, garbage is easy to cut, and the cylindrical drainage grate 3 can cut garbage relative to the ground drainage grate 2 in the cutting motion, so that garbage can be easily penetrated, and garbage retention is reduced. From the above, the transmission mechanism is used for converting the circular motion of the disc 6 into the back-and-forth linear motion of the cylindrical drain grate 3 and the rectangular drain grate 4.
As shown in fig. 2, the drainage system of the present invention further comprises a support plate 8, wherein the outer tray 7 and the lower drainage grate are mounted on the support plate 8, and the support plate 8 is fixed on the outer cover 1.

The first set of holes is a left large circular hole 81 adjacent to the cylindrical drain grate 3. The second set of apertures is a central square array of apertures 82. The third group of holes is a right large round hole 83, which is close to the rectangular drainage grate 4. Wherein, the water and the fine garbage flowing into the middle square array small holes 82 flow to the power mechanism of the drainage system, the mechanical energy of the water flow is converted into the mechanical energy of the power mechanism, and the water and the garbage flowing into the left large round hole 81 and the right large round hole 83 flow to the drainage mechanism of the drainage system.

The vertical connecting rod of the fourth bevel gear 16 to the disc 6 also passes down through the fourth bevel gear 16 and is connected to a spacer 22 (spacer 22 as in fig. 1) provided inside the housing 1 by means of a bearing housing 160, providing support for the fourth bevel gear 16. The conical surfaces of the first bevel gear 13, the second bevel gear 14, the third bevel gear 15 and the fourth bevel gear 16 which are meshed with each other are limited to the outer periphery of the gears, and the central positions of the bevel gears are all planar and are not contacted.

Wherein the middle crawler wheel 20 of the left crawler 17 is fixed outside the horizontal connecting rod between the second bevel gear 14 and the third bevel gear 15, and synchronously rotates along with the horizontal connecting rod. Since the first bevel gear 13 is meshed with the second bevel gear 14, the meshed conical surfaces are limited to the outer periphery of the gears, and the central positions of the two bevel gears are all planar and not contacted, a horizontal connecting rod is fixedly connected to the central plane of the second bevel gear 14, and the horizontal connecting rod rotatably passes through the middle position supporting column 130 and is fixed on the end surface of the middle position crawler wheel 20 of the right crawler belt 18, so that the two middle position crawler wheels 20 realize coaxial synchronous rotation. The second bevel gear 14 rotates clockwise when viewed from the front surface toward the center plane thereof, thereby moving the upper surface of the crawler belt from the lower position to the higher position. The lower crawler wheel 19 of the left crawler 17 and the lower crawler wheel 19 of the right crawler 18 are fixedly connected through a section of horizontal connecting rod in interference fit to realize coaxial synchronous rotation, the horizontal connecting rod is supported by a shorter supporting column, and the supporting column is also fixed on a interlayer 22 arranged inside the outer cover 1.

The garbage discharged from the left and right large circular holes 81 and 83 to the upper side of the track through the discharge pipe is adsorbed on the track during the rotation of the track due to the certain adsorption capacity of the track surface to the large garbage, and moves obliquely upward with the track, and falls into the garbage collection box 10. The refuse and water not adsorbed by the tracks flow downward and out of the tracks, passing through the grid holes of the refuse-permeable plate 9 into the sewer.
Example 2
As a second embodiment of the drainage system of the present invention, three sets of holes formed in the support plate 8 are each provided with a siphon type rain bucket to increase the water flow rate, increase the power transmission, and improve the rotational mechanical energy of the water turbine 12, and the other structures are the same as those of example 1.
The present invention is not limited to the above-described embodiments, and for example, the present invention may be configured to directly drive the water turbine 12 to rotate by electricity to provide the shearing power of the drain grate and the power of the crawler belt rotation without providing the booster propeller 11. The cylindrical drainage grate 3 and the rectangular drainage grate 4 in the lower layer drainage grate are not limited to the cylindrical and rectangular drainage grate, and can be blade pieces which are beneficial to cutting garbage. For example, the grid lines of the cylindrical drainage grating 3 and the long rectangular drainage grating 4 and the grid line of the ground drainage grating 2 can be in a vertical relationship, and can also cross at an angle of 60 degrees, and the lower layer drainage grating moves back and forth along the grid line direction of the ground drainage grating 2.
