Due to the influence of building materials or extreme weather, water droplets will be retained on the bottom of the escalator during use. At the same time, water will accumulate in the well pit used to install the escalator. This will easily cause the components of the escalator to rust, and even cause the electrical components installed in these places to short-circuit and fail. Summary of the invention
[0003] The utility model aims to solve the above problems in the prior art and proposes an anti-water accumulation structure for an outdoor escalator capable of efficiently draining water.

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0024] like Figure 1 — Figure 4 As shown, the anti-water accumulation structure of an outdoor escalator of the utility model includes a truss 100, a lower shaft pit 200, an upper shaft pit 300, an angle a, a first drainage system 400 and a second drainage system 500.
[0025] In the present invention, the bottom surface of the truss 100 close to the upper shaft pit 300 is called an upper bottom surface 140 , and the bottom surface of the truss 100 close to the lower shaft pit 200 is called a lower bottom surface 150 .
[0026] The lower shaft pit 200 supports one end of the truss 100, and the upper shaft pit 300 supports the other end of the truss 100. An angle a is formed between the bottom surface of the truss 100 near one end of the lower shaft pit 200 and the horizontal plane, and between the bottom surface of the truss 100 near one end of the upper shaft pit 300 and the horizontal plane. When the lower shaft pit 200 is located on the floor where the bottom end of the building is located, a second drainage system 500 is provided at the lower shaft pit 200. When the lower shaft pit 200 is located on other floors except the bottom end of the building, a first drainage system 400 is provided at the lower shaft pit 200. The first drainage system 400 and the second drainage system 500 are both located directly below the end of the truss 100 near the lower shaft pit 200. A water collector 110 is provided at the bottom surface of the truss 100 near one end of the lower shaft pit 200. The water collector 110 is located at the bottom of the truss 100 near the lower shaft pit 200. At the lowest point of the lower bottom surface 150, when it rains, rainwater will move from top to bottom along the bottom surface of the truss 100. Furthermore, because there is an angle a between the upper bottom surface 140 and the horizontal plane, the rainwater on the upper bottom surface 140 can move smoothly from top to bottom until it moves to the lower bottom surface 150. There is also an angle a between the lower bottom surface 150 and the horizontal plane, so that the rainwater on the lower bottom surface 150 will also move from top to bottom to the water collector 110. Thereafter, the rainwater will drip through the water collector 110 into the first drainage system 400 or the second drainage system 500. Thereafter, the rainwater will be guided to the outside of the escalator through the first drainage system 400 or the second drainage system 500. In this way, the drainage function of the escalator can be realized to avoid water accumulation at the bottom of the escalator and in the lower shaft pit 200.
[0027] In the utility model, the water collector is equivalent to a solid water baffle, which is used to prevent rainwater from continuing to move relative to the lower bottom surface and provide guidance for rainwater, so that rainwater can drip smoothly along the water collector into the first drainage system or the second drainage system.
[0028] The first drainage system 400 includes a water trough 410 connected to the lower shaft pit 200, and a drain outlet 420 is provided at the bottom of the water trough 410. The water collector 110 is located directly above the water trough 410. During installation, people need to connect the drain outlet 420 to an external water pipe. In this way, when rainwater drips into the water trough 410 through the water collector 110, the rainwater in the water trough 410 will flow into the external water pipe through the drain outlet 420 to complete the drainage function of other floors except the bottom of the building.
[0029] The second drainage system 500 includes a drainage channel 510, which is arranged on the ground. A pit 520 is also provided on the ground for accommodating one end of the truss 100 close to the lower shaft pit 200. The bottom surface of the pit 520 is set as an inclined surface 521. The bottom surface of the pit 520 is also provided with a water inlet 530 connected to the drainage channel 510. When rainwater on the water collector 110 drops into the pit 520, part of the rainwater will directly enter the drainage channel 510 through the water inlet 530, and another part of the rainwater will slide along the trajectory of the inclined surface 521 to the water inlet 530, and then enter the drainage channel 510 through the water inlet 530 to complete the drainage function of the floor where the bottom of the building is located.
[0030] The end of the slope 521 away from the water inlet 530 is higher than the end of the slope 521 close to the water inlet 530. In this way, when rainwater drops onto the slope 521, the rainwater will slide to the water inlet 530 along the trajectory of the slope 521 due to its own gravity, thereby preventing the rainwater from staying on the slope 521.
[0031] The lower shaft pit 200 is provided with a baffle 210 at the water inlet 530, and the baffle 210 is located directly below the water collector 110. When rainwater drips through the water collector 110, the rainwater will first contact the baffle 210, and then splash into the pit groove 520 or directly slide along the trajectory of the baffle 210 to the water inlet 530. In this way, rainwater can be prevented from dripping directly into the drainage channel 510 through the water inlet 530, thereby reducing the impact of rainwater on the drainage channel 510, and then better protecting the drainage channel 510.
[0032] A lower extension plate 120 is provided at one end of the truss 100 close to the lower shaft pit 200, and an upper extension plate 130 is provided at one end of the truss 100 close to the upper shaft pit 300. A lower groove 220 for placing the lower extension plate 120 is provided on the lower shaft pit 200, and an upper groove 310 for placing the upper extension plate 130 is provided on the upper shaft pit 300. When installing the escalator, people need to clamp the upper extension plate 130 of the truss 100 in the upper groove 310 and clamp the lower extension plate 120 in the lower groove 220, so that the escalator can be stably clamped between the upper shaft pit 300 and the lower shaft pit 200.

If the specific posture changes, the directional indication will also change accordingly.
[0034] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
