Technical Field

[0001] The present invention relates to the technical field of prefabricated substations, and specifically relates to a drainage device with a filtering mechanism for a prefabricated substation. Background Art

[0002] A drainage device with a filtering mechanism for a prefabricated substation is a device specifically designed for the internal drainage system of a substation. Its main function is to drain the accumulated water inside the substation, and at the same time prevent debris from entering the drainage system through the filtering mechanism to ensure smooth drainage.

[0003] For the drainage device with a filtering mechanism used in a prefabricated substation, it mainly intercepts impurities such as solid particles, sediment, and leaves in the water through a filtering mechanism such as a filter plate or a filter element. After long-term use, the filtering mechanism is easily blocked by impurities, affecting the drainage effect. Users need to process it regularly, which is very troublesome. Moreover, the water outlet of the drainage device is connected to the sewage pipe. When drainage is not required, since bacteria and mosquitoes are likely to appear in the sewage pipe, the generated bacteria, mosquitoes or odors are likely to enter the prefabricated substation through the water outlet, causing pollution.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; Please refer to Figures 1 to 8 , in the present invention: A drainage device with a filtering mechanism for a prefabricated substation includes a substation main body 1. A drain outlet 2 is opened on the ground of the substation main body 1. A sewage pipe 3 is communicated with the drain outlet 2. An annular groove 4 is opened on the inner wall of the drain outlet 2. A rotating plate 5 is rotatably connected to the inner wall of the annular groove 4. A through hole 6 is opened on the rotating plate 5. A filter plate 7 is threadedly connected to the inner wall of the through hole 6. The top of the filter plate 7 is flush with the rotating plate 5. A waste slot 8 is opened on the top of the rotating plate 5. A treatment tank 9 is opened on the inner top wall of the annular groove 4. A cover plate 10 is threadedly connected to the inner wall of the treatment tank 9. An installation groove 11 is opened on the ground of the substation main body 1. A motor 12 is installed on the inner wall of the installation groove 11. The output shaft of the motor 12 penetrates through the substation main body 1 and is fixedly connected to the rotating plate 5.

[0017] In the present invention, the accumulated water in the substation main body 1 will flow into the drain outlet 2, and then the accumulated water will pass through the filter plate 7 in the through hole 6 and fall into the sewage pipe 3 for discharge, achieving the effect of draining the accumulated water in the substation main body 1. During the drainage process, the sewage will be filtered by the filter plate 7, and the filtered impurities will adhere to the top of the filter plate 7, thus effectively avoiding the situation of the sewage pipe 3 being blocked by impurities; After a period of use, the user can start the motor 12 to drive the rotating plate 5 to rotate in the annular groove 4, which can change the position of the filter plate 7. The connecting part between the inner wall of the water outlet 2 and the inner top wall of the annular groove 4 will slide over the top of the filter plate 7. At this time, the impurities attached to the top of the filter plate 7 will be scraped off, achieving the effect of cleaning the filter plate 7. The cleaned impurities will roll along the top of the rotating plate 5 until the waste slot 8 slides to align with the water outlet 2, and the impurities will fall into the waste slot 8, thereby achieving the effect of collecting impurities. As the rotating plate 5 rotates, the waste slot 8 will slide past the water outlet 2. At this time, the rotating plate 5 will close the through hole 6, effectively avoiding the situation where odors, mosquitoes or bacteria in the sewage pipe 3 enter the substation main body 1 through the water outlet 2 and cause pollution. Moreover, the closed water outlet 2 can effectively prevent the sewage in the sewage pipe 3 from flowing back in rainy weather.

[0018] The user controls the rotation of the rotating plate 5 until the waste slot 8 moves to align with the treatment slot 9. Then, the user can rotate the cover plate 10 to rotate it off the treatment slot 9. Next, the impurities in the waste slot 8 can be cleaned through the treatment slot 9, facilitating the user to clean the filter plate 7 and improving the practicality of the device.

[0019] Please refer to Figures 1 to 6 , in which: an electric push rod 13 is inserted through the ground of the substation main body 1. The telescopic end of the electric push rod 13 is fixedly connected with a baffle 14. The bottom of the baffle 14 is fixedly connected with a cleaning ring 15. Annularly distributed water inlet holes 16 are formed in the cleaning ring 15.

[0020] In the present invention, when the waste slot 8 aligns with the water outlet 2 to discharge impurities, the user can start the electric push rod 13 to drive the baffle 14 to descend. The baffle 14 will drive the cleaning ring 15 to slide along the inner wall of the water outlet 2, thereby scraping off the impurities attached to the inner wall of the water outlet 2, improving the effect of impurities entering the waste slot 8. Moreover, the setting of the baffle 14 can further seal the water outlet 2, further avoiding the situation where odors, mosquitoes or bacteria in the sewage pipe 3 enter the substation main body 1 through the water outlet 2 and cause pollution. Moreover, the baffle 14 can block the water outlet 2 to prevent the situation of staff falling. And the water inlet holes 16 on the cleaning ring 15 can preliminarily filter the sewage, avoiding the situation of large-volume impurities entering the water outlet 2 and improving the working stability of the drainage device.

[0021] Please refer to Figure 5 , in which: a chute 17 is formed at the bottom of the cleaning ring 15. The shape of the chute 17 is trumpet-shaped.

[0022] In the present invention, the situation of impurities adhering to the surface of the cleaning ring 15 can be effectively reduced.

[0023] Please refer to Figure 6 and 7 , wherein: a waste box 18 is slidably connected to the inner wall of the waste chute 8, and a handle 19 is fixedly connected to the inner bottom wall of the waste box 18.

[0024] In the present invention, the waste box 18 can collect impurities instead of the waste chute 8. The user can take out the impurities by pulling out the waste box 18 through the handle 19, which is convenient for the user to clean the impurities.

[0025] Please refer to Figure 8 , wherein: four mounting blocks 20 are fixedly connected to the bottom of the cover plate 10, and heating rods 21 are installed between adjacent two mounting blocks 20.

[0026] In the present invention, after the heating rods 21 are turned on, they can dry and disinfect the impurities in the waste box 18, reduce the volume of the impurities, increase the capacity for storing the impurities, and also avoid the breeding of bacteria or mosquitoes, improving the practicality of the device. Moreover, after the filter plate 7 is moved to align with the cover plate 10, turning on the heating rods 21 can perform drying and disinfection treatment on the filter plate 7.

[0027] Please refer to Figure 5 , wherein: a sealing plate 22 is threadedly connected to the inner wall of the installation groove 11, and anti-slip patterns are provided on the surface of the sealing plate 22.

[0028] In the present invention, the sealing plate 22 can seal the installation groove 11 to prevent sewage from damaging the motor 12 and improve the practicality of the device.

[0029] Please refer to Figure 5 , wherein: a sealing ring 23 is embedded in the inner wall of the annular groove 4, and the top of the sealing ring 23 is in contact with the rotating plate 5.

[0030] In the present invention, the setting of the sealing ring 23 can improve the sealing effect between the annular groove 4 and the rotating plate 5.

[0031] Please refer to Figure 3 , wherein: a signal receiver 24, a signal transmitter 25 and a controller 26 are installed on the wall of the substation main body 1, and the output end of the controller 26 is signal-connected to the motor 12.

[0032] In the present invention, the signal receiver 24 can receive remote instructions and control the motor 12 to start through the controller 26, thereby realizing the effect that the user remotely controls the cleaning of the filter plate 7.
