[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-7 As shown, an energy-saving and environmentally friendly precast concrete component includes a precast staircase assembly 1, which consists of multiple steps 101. Each step 101 has multiple drainage holes 102 on its top and a water collection trough 103 inside each step 101. The width of the drainage holes 102 gradually increases from bottom to top. The drainage holes 102 can increase the anti-slip properties of the upper surface of the step 101 and guide the rainwater on the upper surface of the step 101 into the water collection trough 103, preventing excessive rainwater accumulation on the step 101 and reducing the risk of slipping when workers step on the step 101. A guide plate 104 is connected inside the water collection trough 103 to guide the rainwater.

[0031] It also includes two guard plates 2, which are fixedly installed on both sides of the prefabricated stair component 1. One of the guard plates 2 has a groove 3 inside, and an inspection port 16 is opened on one side of the inner wall of the groove 3. An inspection plate 13 is fixedly installed inside the inspection port 16. A drainage component 4 is fixedly installed inside the groove 3. The drainage component 4 is used to drain the rainwater in the water collection tank 103. There are mounting bolts at the four corners of the inspection plate 13. The inspection plate 13 can be opened by the mounting bolts to maintain and repair the drainage component 4. The drainage component 4 includes a main pipe 41. One side of the main pipe 41 is connected to multiple branch pipes 42. One end of the multiple branch pipes 42 extends into the interior of multiple water collection tanks 103. One end of the main pipe 41 is connected to a drain outlet 43. The rainwater in the water collection tank 103 can enter the main pipe 41 through the branch pipes 42 and then flow out through the drain outlet 43.

[0032] Furthermore, both ends of the prefabricated staircase component 1 are fixedly connected to an extension platform 7. A water storage tank 10 is fixedly installed on one side of one of the extension platforms 7. One end of the drain outlet 43 extends into the interior of the water storage tank 10. Rainwater leaking through the drain outlet 43 can enter the water storage tank 10, which can store rainwater. A cover 14 is installed on the top of the water storage tank 10. The cover 14 is detachable, which facilitates the maintenance of the interior of the water storage tank 10. A filter screen 11 is fixedly installed inside the water storage tank 10. The filter screen 11 is used to filter impurities in the rainwater. A cleaning component 8 is installed inside the water storage tank 10 and on one side of the filter screen 11. The cleaning component 8 is used to clean the filter screen 11 and prevent it from becoming clogged. The cleaning component 8 includes a servo motor 81, which is fixedly installed on one side of the water storage tank 10. A screw 82 is fixedly connected to the output end of the servo motor 81. A slide groove 83 is provided inside the water storage tank 10 for the screw 82 to rotate. A threaded block 84 is threadedly connected to the outer surface of the screw 82. The bottom of the threaded block 84 is slidably connected to the inner wall of the slide groove 83. Driving the servo motor 81 can drive the screw 82 to rotate, and the rotation of the screw 82 can drive the threaded block 84 to slide. A cleaning brush 85 is fixedly connected to one side of the threaded block 84. The bottom of the cleaning brush 85 contacts the filter screen 11, and the threaded block 84 drives the cleaning brush 85 to slide. The cleaning brush 85 can clean the impurities on the filter screen 11. A waste bin 86 is provided inside the water storage tank 10 and on the side away from the drain outlet 43. A door panel 87 is hinged to one side of the front of the water storage tank 10. The cleaning brush 85 pushes the impurities on the filter screen 11 into the waste bin 86. The staff can open the door panel 87 periodically to remove the impurities in the waste bin 86. A water outlet 6 is provided on the other side of the front of the water storage tank 10. A valve is provided on the water outlet 6. Rainwater in the water storage tank 10 can be drawn out and utilized through the water outlet 6 to save water resources and improve the environmental protection of the equipment.

[0033] Furthermore, a filter assembly 9 is installed inside the water storage tank 10 and below the filter screen 11. The filter assembly 9 is used to adsorb dust particles in the rainwater and further purify the rainwater. The filter assembly 9 includes filter cotton 91, which is made of porous sponge to intercept dust particles in the rainwater. A metal mesh 92 is fixedly connected to the bottom of the filter cotton 91. The metal mesh 92 has a certain degree of rigidity and is used to work with the filter screen 11 to squeeze the filter cotton 91, squeezing out the rainwater absorbed inside the filter cotton 91 and making full use of it. Magnetic blocks are fixedly connected to both sides of the metal mesh 92. 93. Both sides of the inner wall of the water storage tank 10 are provided with squeezing grooves 12 for the magnetic block 93 to slide. A switch 95 is provided at the bottom of the inner wall of the squeezing groove 12. The switch 95 is electrically connected to the servo motor 81. A telescopic spring 96 is fixedly connected to the bottom of the inner wall of the squeezing groove 12 and to both sides of the switch 95. The top of the telescopic spring 96 is fixedly connected to the bottom of the magnetic block 93. The filter assembly 9 also includes two electromagnets 94. The two electromagnets 94 are fixedly installed on the top of the inner walls of the two squeezing grooves 12 respectively. When the electromagnets 94 are energized, they are opposite magnetic poles to the magnetic block 93. The electromagnets 94 are electrically connected to the switch 95. When filtering rainwater, filter cotton 91 absorbs rainwater, increasing its weight. When filter cotton 91 absorbs a certain amount of rainwater, its weight causes magnetic block 93 to compress extension spring 96, causing it to touch switch 95. Switch 95 briefly connects the servo motor 81 and electromagnet 94. Electromagnet 94 then generates a magnetic force with magnetic block 93, attracting them to merge. When magnetic block 93 and electromagnet 94 merge, extension spring 96 is stretched, causing magnetic block 93 to move metal mesh 92 upwards. The top of filter cotton 91 then comes into contact with filter mesh 11, and metal mesh 92 compresses the bottom of filter cotton 91, thus compressing the filter cotton 91. The rainwater inside is squeezed out, and the rainwater filtered by the double layer of filter screen 11 and filter cotton 91 can fall to the bottom of the water storage tank 10. At the same time, the servo motor 81 drives the screw 82 to rotate, and the cleaning brush 85 can slide on the filter screen 11 through the threaded block 84, pushing the impurities on the filter screen 11 into the waste bin 86. Then the servo motor 81 reverses to drive the cleaning brush 85 to reset. After the servo motor 81 and the electromagnet 94 are energized, the magnetic block 93 can drive the metal mesh 92 and filter cotton 91 to reset through the elastic force of the telescopic spring 96. This cycle can realize that the equipment can automatically clean the filter screen 11 when a certain amount of rainwater is collected, without the need for manual control, reducing the workload of the staff and making it convenient for the staff to use.

[0034] As can be seen from the above, by setting up the prefabricated staircase component 1 and the drainage component 4, the present invention can drain rainwater from the steps 101 during rainy days, preventing rainwater or other liquids from accumulating on the steps 101, thereby reducing the risk of slipping and falling when workers step on the steps 101, and at the same time preventing the steps 101 from being soaked in water, thus extending the service life of the equipment; by setting up the water storage tank 10, the rainwater drained from the steps 101 can be collected, which is convenient for subsequent use of rainwater, saving water resources and improving the environmental friendliness of the equipment; by setting up the cleaning component 8 and the filter component 9, impurities in the rainwater can be filtered, and when the water storage tank 10 collects a certain amount of rainwater, the impurities on the filter screen 11 can be automatically cleaned without manual control, reducing the workload of workers and making it convenient for workers to use.
