[0040] According to the above structural features of the present application, the embodiments of the present application are further described as follows:

[0041] Referring to Figure 1 , the embodiment provides a low-carbon full-buried sewage treatment system, which comprises an underground space 1, an unmanned operation and maintenance module, an intelligent ventilation module, an intelligent lighting module, and a personnel detection module. The underground space 1 is used for storing sewage, sewage treatment equipment, sewage treatment consumables, etc. The unmanned operation and maintenance module comprises a plurality of functional robots, including a patrol robot, a sampling robot, a garbage and sludge transfer robot, etc., which are provided with a radar or positioning system and can realize lightless and unmanned operation and maintenance, which are all conventional existing technologies in the industry and will not be described in detail. The intelligent ventilation module comprises an air inlet shaft 2, an air outlet shaft 3, a passive ventilation assembly, and an active ventilation assembly; the intelligent lighting module comprises a passive lighting assembly and an active lighting assembly.

[0042] Referring to Figure 1 , the air inlet shaft 2 and the air outlet shaft 3 are respectively communicated with two ends of the underground space 1, thereby reducing the ventilation blind area.

[0043] Referring to Figure 1 and Figure 2The passive ventilation system includes a rotatable wind-catching device 4 mounted on the top of the air intake shaft 2. The wind-catching device 4 includes a wind-catching shell 41 and a first tail fin 42. Air inlets and the first tail fin 42 are respectively located on two opposite sidewalls of the wind-catching shell 41. The wind-catching shell 41 is shaped like a "7" and has a "7"-shaped air intake duct inside, with the air inlet being the upper lateral opening of the air intake duct. External airflow enters the air intake duct through the air inlet and then enters the underground space 1 through the air intake shaft 2. Guided by the first tail fin 42, the wind-catching shell 41 can rotate, ensuring that the air inlet always faces the external airflow, thereby increasing the air intake volume. The top of the air intake shaft 2 and the bottom of the wind-catching shell 41 are connected by a bearing, enabling the wind-catching shell 41 to rotate with the wind. The wind-catching shell 41 is fixedly connected to the first tail fin 42 (e.g., by bolts or welding).

[0044] Reference Figure 1 and Figure 3 A rotatable exhaust device 7 is installed at the top of the exhaust shaft 3. The exhaust device 7 includes a cover 71 and a second tail fin 72. An exhaust port and the second tail fin 72 are located on the same side wall of the cover 71. The cover 71 is shaped like the number 7 and has an exhaust duct shaped like the number 7 inside. The exhaust port is the upper lateral opening of the exhaust duct. Air in the underground space 1 is discharged through the exhaust shaft 3, the exhaust duct, and the exhaust port. Under the guidance of the second tail fin 72, the cover 71 can rotate, so that the exhaust port always faces away from the outside airflow, preventing outside airflow from flowing back into the underground space 1 through the exhaust shaft 3, thereby ensuring the reliability of exhaust in the underground space 1. The bottom end of the cover 71 is rotatably connected to the top end of the exhaust shaft 3 (e.g., through a bearing).

[0045] The active ventilation system includes an intake fan installed in the intake shaft 2 and / or an exhaust fan installed in the exhaust shaft 3. Fan blades are mounted on the output shafts of both the intake fan and the exhaust fan, thereby propelling airflow into or out of the underground space 1.

[0046] Reference Figure 1 and Figure 4 The passive lighting assembly includes several light guide tubes 5 vertically inserted into the soil layer above the underground space 1. Each light guide tube 5 includes a light-collecting cover 51, a tube body 52, and a diffuser 53. The light-collecting cover 51 is fixedly installed at the top of the tube body 52, and the diffuser 53 is fixedly installed at the bottom of the tube body 52. ​​The inner wall of the tube body 52 is coated with a reflective film. The inner cavities of the light-collecting cover 51, the tube body 52, and the diffuser 53 are sequentially connected, thereby guiding external light into the underground space 1.

[0047] The active lighting assembly comprises a lighting lamp 6 and a light sensor installed in the underground space 1. The lighting lamp 6 is fixedly installed on the top surface of the underground space 1 (for example, fixedly connected by bolts); the light sensor is fixedly installed on the top surface of the underground space 1 (for example, fixedly connected by bolts). The light sensor, for example, a light intensity sensor, is used to detect the light intensity in the underground space 1; when the light signal intensity collected by the light sensor is lower than the preset value, the lighting lamp 6 is started to perform light compensation, thereby providing a good working field of view for the user.

[0048] Referring to Figure 1 , the side wall of the air inlet shaft 2 is provided with a first air port 21 and a second air port 22 which respectively communicate with the underground space 1, the first air port 21 is provided with a first electric louver, and the air inlet fan is installed in the second air port 22. When the first electric louver is opened, the airflow in the air inlet shaft 2 can flow into the underground space 1 through the first air port 21 and the second air port 22 (the fan blades connected with the air inlet fan cannot completely block the second air port 22). When the first electric louver is closed and the air inlet fan is opened, the airflow in the air inlet shaft 2 can be driven to flow into the underground space 1 (the first electric louver is closed to avoid backflow of the airflow between the first air port 21 and the second air port 22).

[0049] Referring to Figure 1 , the side wall of the air inlet shaft 2 is provided with a first air port 21 and a second air port 22 which respectively communicate with the underground space 1, the first air port 21 is provided with a first electric louver, and the air inlet fan is installed in the second air port 22. When the first electric louver is opened, the airflow in the air inlet shaft 2 can flow into the underground space 1 through the first air port 21 and the second air port 22 (the fan blades connected with the air inlet fan cannot completely block the second air port 22). When the first electric louver is closed and the air inlet fan is opened, the airflow in the air inlet shaft 2 can be driven to flow into the underground space 1 (the first electric louver is closed to avoid backflow of the airflow between the first air port 21 and the second air port 22).

[0050] The air inlet fan is fixedly installed in the second air port 22 through a support frame, and the air outlet fan is fixedly installed in the fourth air port through a support frame. The support frame and the support frame are both conventional existing technologies in the industry, and the specific structure will not be described here.

[0051] Referring to Figure 5 , the inner cavity of the air inlet shaft 2 is provided with a partition plate 23, and the two sides and the lower part of the partition plate 23 form a U-shaped flow channel 24 for depositing impurity particles (such as dust) in the fresh air. The partition plate 23 is fixedly installed on the inner wall of the air inlet shaft 2 by bolts or welding. The vertical section of the partition plate 23 is in the shape of an inverted L.

[0052] Referring to Figures 6-7The bottom end of the air inlet shaft 2 is provided with a dust collection box 25 which can be pulled out horizontally. When the dust collection box 25 is inserted into the air inlet shaft 2, it is located below the partition plate 23. The dust collection box 25 has a U-shaped vertical cross-section, thereby serving to receive the falling impurity particles. When the airflow flows through the U-shaped flow channel 24, the impurity particles fall into the dust collection box 25 (under the action of gravity and centrifugal force), thereby avoiding the problem of impurity particles entering the underground space 1 along with the airflow.

[0053] With reference to Figures 6-8 , the ground edge position of the underground space 1 is provided with a pit 11, and the dust collection box 25 is placed in the pit 11 and can be moved horizontally under the action of human or mechanical force (such as a mechanical arm). A pressing block 111 with a fan-shaped vertical cross-section is arranged in the pit 11 and can rotate. The middle part of the pressing block 111 is rotationally connected (such as hinged) to the top end of the side wall of the pit 11 away from the air inlet shaft 2. The pressing block 111 can be rotated to abut the dust collection box 25 (see Figure 6 ), or to be pressed on the upper surface position of the ground of the underground space 1 (see Figure 7 ).

[0054] The upper surface of the ground of the underground space 1 is provided with a water retaining slope (for example, fixed by pouring concrete), thereby avoiding the inflow of sewage in the reservoir into the pit 11.

[0055] With reference to Figure 6 and Figure 8 , the pressing block 111 is provided with an outer arc surface, the radius of which is adapted to the vertical distance between the rotation center of the pressing block 111 and the outer side wall of the air inlet shaft 2. The outer side wall of the dust collection box 25 is provided with a pressing arc surface 251 adapted to the outer arc surface. When the pressing block 111 is rotated to press the pressing arc surface 251 with the outer arc surface (at this time, one plane of the pressing block 111 is attached to the inner side wall of the pit 11, and the other plane is adapted to block the top opening of the pit 11, the plane adapted to block the pit 11 can be coplanar with the upper surface of the ground of the underground space 1, thereby improving the safety and convenience of the functional robot or the user, and avoiding the functional robot, the user or the work material from falling into the pit 11); at the same time, the pressing block 111 can limit the dust collection box 25, avoiding the dust collection box 25 from being pulled out, while ensuring the sealing between the dust collection box 25 and the air inlet shaft 2, thereby avoiding the impurity particles from flowing out along with the leaked airflow.

[0056] With reference to Figure 6 and Figure 8The inner wall of the air intake shaft 2 is provided with a limiting block 26 (e.g., fixed by welding or bolts). The limiting block 26 can abut against and limit the upper surface of the end of the dust collection box 25 away from the pressing arc surface 251. Since the outer arc surface presses against the pressing arc surface 251 in a downward angle, the side of the dust collection box 25 away from the pressing arc surface 251 tends to tilt upwards. The limiting block 26 is used to avoid this upward tilting problem and ensure the installation stability of the dust collection box 25 (the side of the dust collection box 25 away from the pressing arc surface 251 tilts upwards, so that...). Figure 6 Taking the shown perspective as an example, the dust collection box 25 tends to rotate clockwise, which will further block the left side of the U-shaped flow channel 24.

[0057] Unlike traditional dust removal techniques, the airflow entering through the air intake shaft 2 in this invention contains moisture. This moisture comes into contact with impurity particles in the dust collection box 25 and then evaporates naturally, causing the impurity particles to clump together and adhere to the dust collection box 25. Therefore, traditional dust removal techniques are ineffective in removing these impurity particles. In this invention, after the user unscrews the pressing block 111, the dust collection box 25 can be pulled out laterally from the air intake shaft 2 and then extracted through the recess 11. This allows the dust collection box 25 and the impurity particles inside it to be removed together, facilitating subsequent cleaning (e.g., using a high-pressure water gun or brush to remove impurity particles adhering to the inner wall of the dust collection box 25) and improving operational convenience.

[0058] Reference Figure 7 The bottom of the side wall of the air inlet shaft 2 is provided with a receiving opening 27, which provides an insertion space for the dust collection box 25. When the dust collection box 25 is inserted into the air inlet shaft 2, the side wall of the dust collection box 25 can be fitted to seal the receiving opening 27, thereby preventing air and dust leakage. The bottom surface of the dust collection box 25 is provided with casters, which facilitates the lateral movement of the dust collection box 25.

[0059] A method for the operation and maintenance of a low-carbon, fully underground sewage treatment system, including operation and maintenance methods.

[0060] The operation method comprises: when the personnel detection module detects that a person enters the underground space 1, the active ventilation assembly and the active lighting assembly are operated; when the personnel detection module does not detect that a person enters the underground space 1, the passive ventilation assembly and the passive lighting assembly are operated. Since the low-carbon full-buried sewage treatment system normally operates by using the unmanned operation module, that is, the functional robot operates with lower requirements for oxygen and light, the natural ventilation (that is, the passive ventilation assembly) and the natural lighting (that is, the passive lighting assembly) are used to ventilate and light the underground space 1. When the user enters the underground space 1, the active ventilation assembly and the active lighting assembly are started to ensure the oxygen supply and the light supply of the user, to ensure the personal safety of the user and to provide a good field of view. The personnel detection module, for example, a satellite positioning system, uses a satellite to locate an electronic device (for example, a mobile phone) carried by a person, so as to determine whether the user enters the low-carbon full-buried sewage treatment system and the specific underground space 1 (the low-carbon full-buried sewage treatment system is provided with a plurality of underground spaces 1, which are respectively used to perform different processes of sewage treatment) in which the user is located.

[0061] The maintenance method comprises the following steps: S1, a first handle on the surface of the crimping block 111 is gripped, the crimping block 111 is rotated out of the pit 11, and then the crimping block 111 is (naturally) crimped on the surface of the ground of the underground space 1; S2, a second handle on the outer wall of the dust collection box 25 is gripped, the dust collection box 25 is pulled out of the air inlet well 2, and the dust collection box 25 is placed in the pit 11; S3, the dust collection box 25 is lifted, and the dust collection box 25 is taken out of the pit 11; S4, impurity particles in the dust collection box 25 are cleaned; S5, the dust collection box 25 is placed into the pit 11 and pushed into the air inlet well 2; and S6, the first handle on the surface of the crimping block 111 is gripped, the crimping block 111 is rotated into the pit 11, and the outer arc surface is crimped on the crimping arc surface 251.

[0062] When the crimping block 111 is rotated into the pit 11, the bottom end of the crimping block 111 crimps the inner cavity bottom surface of the pit 11, so that, compared with a traditional overhead cover plate, the crimping block 111 has stronger bearing capacity, and the functional robot (and other engineering machinery) crimped on the crimping block 111 will not cause the crimping block 111 to sag, so that the functional robot does not need to avoid the pit 11, thereby having a larger range of motion.

[0063] The low-carbon full-buried sewage treatment system further comprises an electrical cabinet, which is fixedly installed on the top of the side wall of the underground space 1 through bolts; the air inlet fan, the air outlet fan, the light sensor, the illuminating lamp 6, the first electric shutter and the second electric shutter are connected with the electrical cabinet through wires and signal lines respectively; the electrical cabinet is connected with an external power supply and an external computer through wires and signal lines respectively, and the functional robot is connected with the external computer through wireless connection, and the computer controls the start-stop and other working states of the air inlet fan, the air outlet fan, the light sensor, the illuminating lamp 6, the first electric shutter, the second electric shutter and the functional robot in the application.

[0064] The low-carbon full-buried sewage treatment system further comprises an intelligent monitoring module, which comprises sensors (such as pH sensors, pressure sensors, liquid level sensors, oxygen content sensors, ammonia content sensors, nitrogen content sensors and other sensors for monitoring various parameters in the sewage treatment process) and a camera arranged in the underground space, the camera is provided with a night vision assembly, a heat source monitoring assembly and a voiceprint recognition assembly, the sensors and the camera are connected with the electrical cabinet through wires and signal lines respectively, and an external computer is arranged in an aboveground control room. The monitoring personnel can evaluate the operation of each process section of the sewage treatment according to the data information collected by the intelligent monitoring module in the aboveground control room. When an abnormal gas parameter (such as oxygen content lower than a threshold value or ammonia content higher than a threshold value) is detected in a certain underground space 1, the active ventilation assembly is started to accelerate ventilation, and the inspection robot drives into the underground space 1 to collect data or cooperate with work. When an abnormal light parameter is detected in a certain underground space 1, the active lighting assembly is started to supplement light, and the inspection robot drives into the underground space 1 to collect data or cooperate with work. The top surface of the underground space 1 is provided with a light window for natural light irradiation. When the natural light is sufficient (monitored by the light sensor), the camera enters a low-power mode and only the color recognition function is enabled; when the natural light is insufficient, the built-in night vision assembly (i.e. infrared light supplement assembly) is started.

[0065] The underground space 1 is a basement.

[0066] The application has the advantages of simple structure and reliable function; when there is no one in the underground space 1, the unmanned operation and maintenance module is used to maintain the operation of the low-carbon full-buried sewage treatment system, the passive ventilation assembly and the passive lighting assembly are used to ventilate and illuminate the underground space 1, and the energy consumption is low; when a user enters the underground space 1, the active ventilation assembly and the active lighting assembly are used to enhance the ventilation intensity and the illumination intensity, so as to protect the life safety of the user and provide a good field of view, thereby facilitating the underground operation of the user.
