[0008] The slope of the top of the step is used to transmit rainwater to the water inlet trough, so that the water inlet trough transmits the rainwater to the drainage trough set on the top of the platform plate through the slope. The rainwater on the top of the slope will be transmitted to the drainage trough through the slope of the slope, and part of the rainwater will flow to the step surface, so that the step surface will transmit the rainwater to the water inlet trough again, so that the device can be more convenient in the drainage process, and there will be no irregular flow of rainwater.

[0022] Furthermore, by setting up the filter, when the top of the gutter receives rainwater, larger particles or objects such as leaves in the rainwater can be intercepted by the filter, thereby preventing the gutter from being blocked by objects during drainage, thereby increasing the protectiveness of the device.

[0031] Example 1:

[0032] In order to solve the problem that the stair ramp in the prior art is difficult to drain and thus effectively drain, the following solution is disclosed. Figure 1-5 The utility model provides a technical solution: a stair ramp drainage device, comprising a stair body 1, a slope 9 connected to the middle of the stair body 1, a step surface 2 provided on the top of the stair body 1, and the middle of the stair body 1 is connected to the slope 9, and water inlet grooves 10 are provided on the left and right sides of the outer side of the slope 9, and the water inlet grooves 10 are located on the inner top of the step surface 2;

[0033] The rear side of the top of the staircase body 1 is connected to the crossbeam 7, and the front side of the bottom of the staircase body 1 is provided with a platform board 15, and the top of the platform board 15 is provided with a drainage trough 13, and the front side of the platform board 15 is connected to a sewer 16, and the sewer 16 is connected to the drainage trough 13 by waterway;

[0034] When the stair ramp drainage device is used, rainwater will drip onto the step 2 and the slope 9 at the top of the stair body 1, so that the rainwater on the top of the step 2 flows into the water inlet trough 10 through the slope of the top of the step 2, and the rainwater on the top of the slope 9 flows to the platform 15 through the slope of the slope 9, and part of the rainwater will flow to the step 2, so that the step 2 will divert the rainwater to the water inlet trough 10 again through the slope, and the rainwater will be diverted to the drainage trough 13 set at the top of the platform 15 through the slope 9 and the water inlet trough 10, and then the rainwater will be transmitted to the sewer 16 through the drainage trough 13 to complete the stair drainage work;

[0035] A waterproof cushion layer 3 is provided on the top of the step surface 2, and the waterproof cushion layer 3 has an inclination angle, with the inner side being lower than the outer side, and a fixed anchor 5 is provided on the top of the step surface 2. The waterproof cushion layer 3 is fixedly connected to the step surface 2 through the fixed anchor 5, and a rubber convex layer 4 is connected to the top of the waterproof cushion layer 3;

[0036] A corner protection layer 6 is provided at the front end of the step surface 2, and the corner protection layer 6 is fixedly connected to the waterproof cushion layer 3, and the inner sides of the waterproof cushion layer 3 and the corner protection layer 6 are in contact with the slope 9; a throttle valve 11 is provided inside the slope 9, and the left and right ends of the throttle valve 11 are fixedly connected to the water inlet trough 10, and a drain valve 12 is provided at the bottom of the throttle valve 11;

[0039] When the step surface 2 is draining rainwater, the waterproof cushion layer 3 on the top of the step surface 2 has an inward slope, so it will drain the rainwater to the water inlet trough 10. Moreover, since the rubber convex layer 4 is provided on the top of the waterproof cushion layer 3, when pedestrians walk on the top of the waterproof cushion layer 3, the uneven rubber convex layer 4 can increase the grip and friction, thereby preventing pedestrians from slipping when walking.

[0041] Working principle: When the stair ramp drainage device is used, rainwater will drip onto the step 2 and slope 9 at the top of the stair body 1, so that the rainwater on the top of the step 2 flows into the water inlet trough 10 through the slope of the top of the step 2, and the rainwater on the top of the slope 9 flows to the platform board 15 through the slope of the slope 9, and part of the rainwater will flow to the step 2, so that the step 2 will divert the rainwater to the water inlet trough 10 again through the slope, and the rainwater will be diverted to the drainage trough 13 set at the top of the platform board 15 through the slope 9 and the water inlet trough 10, and then the rainwater will be transmitted to the sewer 16 through the drainage trough 13 to complete the stair drainage work;

[0042] When the step surface 2 is draining rainwater, the waterproof cushion layer 3 on the top of the step surface 2 has an inward slope, so it will drain the rainwater to the water inlet trough 10. Moreover, since the rubber convex layer 4 is provided on the top of the waterproof cushion layer 3, when pedestrians walk on the top of the waterproof cushion layer 3, the uneven rubber convex layer 4 can increase the grip and friction, thereby preventing pedestrians from slipping when walking.

[0043] When the water inlet trough 10 is transmitting rainwater, the rainwater can be transmitted to the inside of the drain valve 12 through the throttle valve 11, so that the drain valve 12 transmits the rainwater to the drain trough 13 set on the top of the platform plate 15, and by setting a filter screen 14 on the top of the drain trough 13, the filter screen 14 can intercept larger objects, thereby avoiding the problem of clogging of the drain trough 13.
