Technical Field

[0001] The present invention relates to the technical field of subway flood control supporting facilities, and particularly to a cleaning device for subway station flood control drainage ditches. Background Art

[0002] Subway flood control drainage ditches are an important part of the subway flood control system, mainly used to quickly drain rainwater and accumulated water to prevent waterlogging in stations and tunnels during heavy rain. Regular cleaning of subway flood control drainage ditches is crucial for the following reasons: Debris accumulation: Leaves, garbage, sediment, etc. will enter the drainage ditch with rainwater. Long-term accumulation will block the ditch and pipes, resulting in a decrease in drainage speed or even a complete interruption. Pump station protection: If the sump and water pump connected to the end of the drainage ditch are blocked by debris (such as plastics, branches), it may cause the water pump to run idly, overheat or burn out, affecting the emergency drainage capacity. See Figure 1 As shown in the figure, a cover plate is usually laid on the subway station flood control drainage ditch 100 in the prior art. Different from ordinary drainage ditches, the subway station flood control drainage ditch is a crowded place, and many people step on the cover plate every day, often causing the cover plate to crack, so there are safety hazards.

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Embodiment 1

[0023] As Figures 1 to 8 shown, a subway station flood control drainage ditch cleaning device provided by the present invention includes a top plate 1. The top plate 1 is a rectangular plate. There are two rotation holes on the top plate 1. Two guide sleeves 11 are rotatably connected in each rotation hole. A base pipe 2 is slidably connected in each guide sleeve 11. A positioning groove is provided on the inner wall of the guide sleeve 11. A positioning rod 20 is fixedly connected to the outside of the base pipe 2. The positioning rod 20 is slidably connected in the positioning groove. This setting enables the base pipe 2 to rotate or remain stationary following the guide sleeve 11 while sliding up and down along the guide sleeve 11.

[0024] A box body 4 is provided on the lower side of each base pipe 2. The lower part of the box body 4 is open. A cleaning pipe 6 is provided in the base pipe 2. The lower end of the cleaning pipe 6 extends into the box body 4. Water inlet and outlet openings are provided on the side wall of the part of the cleaning pipe 6 extending into the box body 4. A plurality of cleaning plates 61 are fixedly connected to the lower end of the cleaning pipe 6. Two rotating devices 3 and two lifting devices 5 are installed on the top plate 1. The rotating device 3 includes a motor 31. A gear 32 is fixedly connected to the main shaft of the motor 31. A toothed ring 33 is sleeved outside the guide sleeve 11. The toothed ring 33 meshes with the gear 32. The rotating device 3 is used to drive the top plate 1 to rotate around the guide sleeve 11. The lifting device 5 is used to drive the base pipe 2 to move up and down.

[0025] During use, first, one of the base pipes 2 and the box body 4 are lifted by the lifting device 5, and the other box body 4 is placed into the flood control drainage ditch 100. The width and height of the box body 4 match the width and height of the flood control drainage ditch 100, and the length of the box body 4 matches the distance between two adjacent support beams 200. After the box body 4 is placed into the flood control drainage ditch 100 in this way, a sealed space is formed inside the box body 4. Then, high-pressure water is sprayed into the box body 4 through the cleaning pipe 6, and the flood control drainage ditch 100 in the internal area of the box body 4 is flushed clean by the high-pressure water. Then, the cleaning pipe 6 is evacuated, so that the flushed impurities are discharged from the cleaning pipe 6 again. During the cleaning process, the cleaning pipe 6 is rotated, and the silt at the bottom of the flood control drainage ditch 100 can also be scraped clean by the cleaning plate 61. During the process of placing the box body 4, the side wall of the box body contacts the side wall of the flood control drainage ditch 100 and continuously descends, so that the silt on the side wall of the flood control drainage ditch 100 is scraped clean. After the cleaning of this area is completed, the top plate 1 is driven to rotate around the guide sleeve 11 by the rotating device 3. In this way, the other base pipe 2 and the box body 4 also rotate with the top plate 1. After the top plate 1 rotates 180°, the base pipe 2 and the box body 4 are exactly above the flood control drainage ditch 100. The base pipe 2 and the box body 4 are lowered by the lifting device 5, and the box body 4 is exactly placed into the flood control drainage ditch 100 again and is located between two support beams 200. The flood control drainage ditch 100 is cleaned again in the same way. Repeating like this can make the subway station flood control drainage ditch cleaning device continuously move forward and clean. The support beam 200 will not affect its walking operation.

[0026] Embodiment 2

[0027] In Embodiment 1, the box body 4 rises or falls to clean the flood control drainage ditch 100. However, during the rising or falling process of the box body 4, the box body 4 can never cover the area directly below the support beam 200 in the flood control drainage ditch 100. Therefore, the area directly below the support beam 200 cannot be cleaned. To solve this problem, in this embodiment, a through groove is provided at the center of the top of the box body 4, a moving block 41 is arranged in the through groove, relief grooves are arranged on both sides of the moving block 41, the box wall at the top of the box body 4 is in the relief grooves, the moving block 41 can slide horizontally back and forth at the relief grooves, and a first spring 42 is fixedly connected between the bottom of the relief groove and the side wall of the through groove. With such a setting, after the box body 4 is placed into the flood control drainage ditch 100, the box body 4 is pushed forward a certain distance. In this way, during the forward movement of the box body 4, the silt directly below the support beam 200 can be pushed forward, so that the silt in this part is pushed between the two support beams 200. In this way, when the box body 4 is placed into the flood control drainage ditch 100 next time, this part of the silt can be covered and cleaned together.

[0028] In order to enable the box body 4 to translate, a corresponding power device is required. In this application, a form combining a lifting device with the translation of the box body 4 is adopted, that is, after the lifting device drives the box body to descend, it can also make it move forward a certain distance at the same time. To achieve this function, in this embodiment, a central hole is provided on the upper side of the moving block 41, and the base pipe 2 passes through the central hole. A first retaining ring 21 and a second retaining ring 22 are fixedly connected to the base pipe 2. The first retaining ring 21 is located above the moving block 41, and the second retaining ring 22 is located below the moving block 41. A second spring 23 is installed between the moving block 41 and the first retaining ring 21. When the second spring 23 is in a free state, under the elastic force of the second spring 23, the box body 4 is at the lowermost end of the base pipe 2, and the cleaning pipe 6 and its cleaning plate 61 are both at the uppermost part inside the box body 4. The lifting device 5 includes an electric telescopic rod 51. The telescopic end of the electric telescopic rod 51 is fixedly connected to a lifting shaft 52. One side of the lifting shaft 52 is fixedly connected to a collar 50 through a connecting rod 53. An annular groove is provided on the outer side of the base pipe 2, and the collar 50 is rotatably connected in the annular groove. A bracket 55 is fixedly connected to the lifting shaft 52, and an extrusion wheel 56 is fixedly connected to the bracket 55. A support seat 57 is fixedly connected to the upper side of the box body 4, and an inclined extrusion plate 58 is fixedly connected to one side of the support seat 57. The extrusion wheel 56 can contact the extrusion plate 58 during the descending process. The electric telescopic rod 51 is used to push the cleaning pipe 6 and the box body 4 to move downward together. After the box body 4 contacts the bottom of the flood control drainage ditch 100, the electric telescopic rod 51 pushes the cleaning pipe 6 to continue descending. The extrusion wheel 56 will contact the extrusion plate 58 as the cleaning pipe 6 continues to descend. Under the action of the inclined surface of the extrusion plate 58, a lateral thrust will be generated on the box body 4, so that the box body 4 moves forward a certain distance, thereby pushing the silt forward.

[0029] To improve the stability of the lifting device, a circular ring 43 is rotatably connected above the moving block 41. A support pipe 54 is fixedly connected to the upper side of the circular ring 43. The lifting shaft 52 is inserted into the support pipe 54 and can move up and down along the support pipe 54, so as to support the lower end of the lifting shaft 52 and prevent the lifting device from tilting due to uneven force during operation.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
