[0019] The specific implementation of the utility model will be further explained below in combination with the drawings.

[0020] In order to facilitate understanding of the utility model, the utility model will be explained in more detail in combination with the drawings and specific examples. The preferred embodiments of the utility model are given in the drawings. However, the utility model can be realized in many different forms, and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.

[0021] It should be noted that, unless otherwise defined, all technical and scientific terms used in the present application have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0022] As shown in Figures 1-3 A subway tunnel drainage structure, comprising a tunnel floor 1, the tunnel floor 1 is provided with a drainage ditch 3 along the left and right directions, the upper end of the drainage ditch 3 is provided with a cover plate 6, the drainage ditch 3 is provided with at least two, the drainage ditch 3 is provided with an auger 4 with the same axis as the drainage ditch 3, the drainage ditch 3 is provided with a motor 5 for driving the auger 4 to rotate, the upper end of the drainage ditch 3 is provided with a branch water pipe 13 parallel to the auger 4, the branch water pipe 13 is provided with a plurality of nozzles 11 facing the auger 4, one end of the tunnel floor 1 is provided with a sedimentation tank 7 communicating with the drainage ditch 3, the sedimentation tank 7 is provided with a water tank 9, the water tank 9 is provided with a water pump, and the water pump is connected with each branch water pipe 13 through a main water pipe 10.

[0023] In this embodiment, the arrow direction is the passenger flow direction, and the middle part of the tunnel floor 1 is provided with a 1% slope towards the drainage ditch 3, which facilitates the water to flow into the drainage ditch 3 under the influence of gravity and then flow into the sedimentation tank 7 for storage. When the impurities in the drainage ditch 3 accumulate too much, the auger 4 can be used for regular cleaning. By starting the motor 5, the output shaft of the motor 5 drives the auger 4 to rotate, stirs the impurities in the drainage ditch 3 and continuously transports them into the sedimentation tank 7, which facilitates centralized processing and eliminates the need for frequent opening of the cover plate 6 on the drainage ditch 3 to clean the impurities, thereby affecting the passage of passengers. At the same time, by starting the water pump, the water in the water tank 9 is pumped into the main water pipe 10 and then sprayed out through the multiple nozzles 11 on the branch water pipe 13 to wash away the impurities remaining on the blades of the auger 4, ensuring the cleanliness of the auger 4 and facilitating the maintenance effect.

[0024] As shown in Figure 2 The motor 5 is a waterproof motor 5.

[0025] In this embodiment, the waterproof motor 5 has a high IP protection level, improving durability.

[0026] As shown in Figure 1 The drainage ditch 3 is provided with an access plate 12 above it.

[0027] In this embodiment, the access plate 12 is located above the motor 5 to protect the motor 5, and when maintenance is needed, the access plate 12 can be directly removed for maintenance of the motor 5.

[0028] As shown in Figure 1 The sedimentation tank 7 is provided with a protective plate 8 above it.

[0029] In this embodiment, by setting a protective plate 8 to cover the entrance of the sedimentation tank 7, people can step on it without affecting passenger passage. When too many impurities are collected in the sedimentation tank 7, the protective plate 8 can be removed to clean the impurities in the sedimentation tank 7.

[0030] like Figure 3 As shown, a drain pipe 14 is installed on one side of the sedimentation tank 7, and a valve is installed on the drain pipe 14.

[0031] In this embodiment, the other end of the drain pipe 14 is connected to the sedimentation tank 7. When the water level in the sedimentation tank 7 reaches a predetermined height, a pumping device can be used to connect the drain pipe 14 and open the valve to pump out the water in the sedimentation tank 7.

[0032] like Figure 2 As shown, drainage ditch 3 is designed with a slope of 1.5%.

[0033] In this embodiment, by setting a slope, the water in the drainage ditch 3 automatically flows into the sedimentation tank 7 for collection under the action of gravity.

[0034] Working principle: When there is a lot of impurities in the drainage ditch 3, the auger 4 can be used for regular cleaning. By starting the motor 5, the output shaft of the motor 5 drives the auger 4 to rotate, stirring the impurities in the drainage ditch 3 and continuously conveying them to the sedimentation tank 7 for centralized treatment. After cleaning, in order to prevent impurities from sticking to the blades of the auger 4 and affecting the cleaning effect next time, the water pump in the water tank 9 is started to pump the water in the water tank 9 into the main water pipe 10 and then spray it out through multiple sets of nozzles 11 on the branch water pipe 13 to wash away the remaining impurities on the blades of the auger 4, ensuring the cleanliness of the auger 4 and maintaining the subsequent cleaning effect. When the rainwater collected in the sedimentation tank 7 reaches the predetermined height, the water in the sedimentation tank 7 can be pumped out by connecting the drainage pipe 14 with a pumping device and opening the valve. Then, by opening the protective plate 8, the impurities collected in the sedimentation tank 7 can be cleaned with cleaning tools.

For example, the term "joined" can refer to a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can refer to the internal communication of two components or the interaction between two components. Therefore, unless otherwise expressly limited in this specification, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] According to the above description of the present specification, those skilled in the art can also understand that the terms used such as "upper", "lower", "front", "back", "left", "right", "length", "width", "thickness", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", "center", "longitudinal", "transverse", "clockwise" or "counterclockwise" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the present specification, which are only for the purpose of facilitating the description of the present application and simplifying the description, and are not explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in a specific orientation, therefore the above orientation or positional relationship terms cannot be understood or interpreted as a limitation on the technical solutions of the present application.
