[0019] (4) The dust box can be pulled out horizontally in the air inlet shaft, and after being taken out through the pit, the adhered / compacted impurity particles can be easily cleaned, thereby avoiding the problem that the dust box is located in the air inlet shaft and has a small operating space, which makes it difficult for traditional dust removal technology to remove adhered / compacted impurity particles.

[0020] (5) The crimping block is provided with an outer arc surface, which can adapt to the crimping arc surface abutting against the side wall of the dust box, thereby stably limiting the dust box in the air inlet shaft to avoid the problem of the dust box accidentally falling out.

[0040] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0041] Reference Figure 1 , this embodiment provides a low-carbon, fully buried sewage treatment system, including 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 to store sewage, sewage treatment equipment, sewage treatment consumables, etc. The unmanned operation and maintenance module includes a number of functional robots, including inspection robots, sampling robots, garbage and sludge transfer robots, etc., which are equipped with radar or positioning systems and can realize lightless and unmanned operation and maintenance. They are all conventional existing technologies in the industry and will not be described in detail. The intelligent ventilation module includes an air inlet shaft 2, an exhaust shaft 3, a passive ventilation component and an active ventilation component; the intelligent lighting module includes a passive lighting component and an active lighting component.

[0042] Reference Figure 1 The air inlet shaft 2 and the air exhaust shaft 3 are respectively connected to the two ends of the underground space 1, thereby reducing the ventilation blind area.

[0043] Reference Figure 1 and Figure 2The passive ventilation component includes a wind-catching device 4 installed at the top of the air inlet shaft 2 and capable of rotating. The wind-catching device 4 includes a wind-catching shell 41 and a first tail wing 42; the two opposite side walls of the wind-catching shell 41 are respectively provided with an air inlet and the first tail wing 41; the wind-catching shell 41 is in a 7-shaped shape and is provided with an air inlet duct in a 7-shaped shape inside, and the air inlet is the upper lateral opening of the air inlet duct. The outside air flows into the air inlet duct through the air inlet, and then enters the underground space 1 through the air inlet shaft 2. Under the guidance of the first tail wing 42, the wind-catching shell 41 can rotate, so that the air inlet can always face the outside air flow, thereby increasing the air intake. The top of the air inlet shaft 2 is connected to the bottom of the wind-catching shell 41 through a bearing, so that the wind-catching shell 41 can rotate with the wind; the wind-catching shell 41 is fixedly connected to the first tail wing 42 (for example, fixedly connected by bolts or fixedly connected by 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 shell 71 and a second tail wing 72; an exhaust port and a second tail wing 72 are provided at the same side wall position of the cover shell 71. The cover shell 71 is in the shape of a figure 7 and is provided with an exhaust air duct in the shape of a figure 7 inside, and the exhaust port is the lateral opening at the upper part of the exhaust air duct; the air in the underground space 1 is discharged through the exhaust shaft 3, the exhaust air duct and the exhaust port. Under the guidance of the second tail wing 72, the cover shell 71 can rotate so that the exhaust port is always facing away from the external airflow, avoiding the external airflow from flowing back into the underground space 1 through the exhaust shaft 3, thereby ensuring the exhaust reliability of the underground space 1. The bottom end of the cover shell 71 is rotatably connected to the top of the exhaust shaft 3 (for example, connected by a bearing).

[0045] The active ventilation assembly includes an air intake fan installed in the air intake shaft 2 and / or an exhaust fan installed in the exhaust shaft 3. Fan blades are respectively installed on the output shafts of the air intake fan and the exhaust fan, thereby driving the air flow into or out of the underground space 1.

[0046] Reference Figure 1 and Figure 4 The passive lighting assembly includes a plurality of light guides 5 longitudinally inserted into the soil layer above the underground space 1. The light guide 5 includes a light cover 51, a tube body 52 and a diffuser cover 53; the light cover 51 is fixedly mounted on the top of the tube body 52, the diffuser cover 53 is fixedly mounted on the bottom of the tube body 52, and the inner wall of the tube body 52 is coated with a reflective film. The inner cavity of the light cover 51, the inner cavity of the tube body 52 and the inner cavity of the diffuser cover 53 are connected in sequence, so as to guide the external light into the underground space 1.

[0047] The active lighting assembly includes 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, such as 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 a preset value, the lighting lamp 6 is started to provide supplementary light, thereby providing a good working field for the user.

[0048] Reference Figure 1 The side wall of the air inlet shaft 2 is provided with a first air vent 21 and a second air vent 22 which are respectively connected to the underground space 1. A first electric venetian blind is installed in the first air vent 21, and an air inlet fan is installed in the second air vent 22. When the first electric venetian blind is opened, the airflow in the air inlet shaft 2 can flow into the underground space 1 through the first air vent 21 and the second air vent 22 (the blades connected to the air inlet fan cannot completely block the second air vent 22). When the first electric venetian blind is closed and the air inlet fan is turned on, the airflow in the air inlet shaft 2 can be driven to flow into the underground space 1 (closing the first electric venetian blind is used to avoid the backflow of airflow between the first air vent 21 and the second air vent 22).

[0049] Reference Figure 1 The side wall of the exhaust shaft 3 is provided with a third air vent and a fourth air vent respectively connected to the underground space 1, a second electric blind is installed in the third air vent, and the exhaust fan is installed in the fourth air vent. When the second electric blind is opened, the airflow in the underground space 1 can flow into the exhaust shaft 3 through the third air vent and the fourth air vent (the blades connected to the exhaust fan cannot completely block the second air vent 22). When the second electric blind is closed and the exhaust fan is turned on, the airflow in the underground space 1 can be driven to flow into the exhaust shaft 3 (closing the second electric blind is used to avoid the backflow of airflow between the third air vent and the fourth air vent).

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

[0051] Reference Figure 5 A partition plate 23 is provided at the bottom of the inner cavity of the air inlet shaft 2, and a U-shaped flow channel 24 is formed on both sides and below the partition plate 23 for depositing foreign 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 an inverted L-shape.

[0052] Reference Figure 6-7A dust box 25 that can be pulled out laterally is provided at the bottom of the air inlet shaft 2. When the dust box 25 is inserted into the air inlet shaft 2, it is located below the partition plate 23. The vertical section of the dust box 25 is U-shaped, so as to receive the fallen impurity particles. When the airflow flows through the U-shaped flow channel 24, the impurity particles fall into the dust box 25 (under the action of its own gravity and centrifugal force), thereby avoiding the problem of impurity particles entering the underground space 1 with the airflow.

[0053] Reference Figure 6 to Figure 8 A pit 11 is provided at the ground edge of the underground space 1, and a dust box 25 is placed in the pit 11 and can be moved laterally under the action of human or mechanical force (such as a mechanical arm). A crimping block 111 with a fan-shaped vertical section and capable of rotation is provided in the pit 11. The middle part of the crimping block 111 is rotatably connected (for example, hinged) to the top of the side wall of the pit 11 away from the air inlet shaft 2; the crimping block 111 can be rotated to abut against the dust box 25 (refer to Figure 6 ), or rotate to the position where it is pressed against the upper surface of the ground in the underground space 1 (refer to Figure 7 ).

[0054] A water retaining slope (for example, fixed by concrete pouring) is provided on the upper surface of the ground of the underground space 1 to prevent sewage in the reservoir from flowing into the pit 11 .

[0055] Reference Figure 6 and Figure 8 The crimping block 111 is provided with an outer arc surface, the radius of the outer arc surface is adapted to the vertical distance between the rotation center of the crimping block 111 and the outer wall of the air inlet shaft 2, and the upper part of the outer wall of the dust box 25 is provided with a crimping arc surface 251 adapted to the outer arc surface. When the crimping block 111 rotates to the outer arc surface, the crimping arc surface 251 is crimped (at this time, one plane of the crimping block 111 is in contact with the inner wall of the pit 11, and the other plane is adapted to block the top opening of the pit 11, and the plane used to adapt to block the pit 11 can be coplanar with the upper surface of the ground of the underground space 1, thereby improving the operating safety and convenience of the functional robot or user, and preventing the functional robot, user or operating materials from falling into the pit 11); at the same time, the crimping block 111 can limit the dust box 25 to prevent the dust box 25 from falling out, while ensuring the sealing between the dust box 25 and the air inlet shaft 2 to prevent foreign particles from flowing out with the leaked airflow.

[0056] Reference Figure 6 and Figure 8The inner wall of the air inlet shaft 2 is provided with a stopper 26 (for example, welded or bolted), and the stopper 26 can abut against and stop the upper surface of the end of the dust box 25 away from the crimping arc surface 251. Since the outer arc surface is crimped to the crimping arc surface 251 in an oblique downward manner, the side of the dust box 25 away from the crimping arc surface 251 has a tendency to tilt upward, and the stopper 26 is used to avoid the upward tilting problem, thereby ensuring the installation stability of the dust box 25 (the side of the dust box 25 away from the crimping arc surface 251 tilts upward to prevent the dust box 25 from tilting upward). Figure 6 Taking the perspective shown as an example, the dust box 25 has a tendency to rotate clockwise, which will further cause the left side of the U-shaped flow channel 24 to be blocked).

[0057] Different from the traditional dust cleaning technology, the airflow flowing into the air inlet shaft 2 in the present invention contains moisture, which will evaporate naturally after contacting with the impurity particles in the dust box 25, causing the impurity particles to agglomerate and adhere to the dust box 25. Therefore, it is difficult to remove the impurity particles with the traditional dust removal technology. In the present invention, after the user unscrews the crimping block 111, the dust box 25 can be pulled out horizontally from the air inlet shaft 2, and then extracted from the pit 11, and the dust box 25 and the impurity particles in the dust box 25 can be taken out together, which is convenient for later cleaning (for example, using a high-pressure water gun or a brush to clean the impurity particles adhering to the inner wall of the dust box 25), and improves the convenience of operation.

[0058] Reference Figure 7 The bottom of the side wall of the air inlet shaft 2 is provided with a receiving opening 27, which is used to provide an insertion space for the dust box 25; when the dust box 25 is inserted into the air inlet shaft 2, the side wall of the dust box 25 can be adapted to block the receiving opening 27, thereby preventing air leakage and dust leakage. The bottom surface of the dust box 25 is provided with moving wheels, thereby facilitating the lateral movement of the dust box 25.

[0059] An operation and maintenance method for a low-carbon fully buried sewage treatment system, including an operation method and a maintenance method.

[0060] The operation method includes: when the personnel detection module detects that a person has entered the underground space 1, the active ventilation component and the active lighting component are operated; when the personnel detection module does not detect that a person has entered the underground space 1, the passive ventilation component and the passive lighting component are operated. Since the low-carbon fully buried sewage treatment system uses an unmanned operation and maintenance module to operate under normal conditions, that is, the functional robot has low requirements for oxygen and light when operating, natural ventilation (i.e., passive ventilation components) and natural lighting (i.e., passive lighting components) are used to ventilate and illuminate the underground space 1. When the user enters the underground space 1, the active ventilation component and the active lighting component are started to ensure the oxygen supply and light supply of the user, ensure their personal safety and provide a good field of vision. The personnel detection module, such as a satellite positioning system, uses satellite positioning of the user's portable electronic device (such as a mobile phone), so as to determine whether the user has entered the low-carbon fully buried sewage treatment system, and in which underground space 1 the user is specifically located (a plurality of underground spaces 1 are provided in the low-carbon fully buried sewage treatment system, which are respectively used to perform different processes of sewage treatment).

[0061] The maintenance method includes the following steps: S1, grab the first handle on the surface of the crimping block 111, rotate the crimping block 111 out of the pit 11, and then crimp the crimping block 111 (naturally) on the upper surface of the ground of the underground space 1; S2, grab the second handle on the outer wall of the dust box 25, pull the dust box 25 out of the air inlet shaft 2, and place the dust box 25 in the pit 11; S3, lift the dust box 25, and take the dust box 25 out of the pit 11; S4, clean the foreign particles in the dust box 25; S5, place the dust box 25 into the pit 11 and push it into the air inlet shaft 2; S6, grab the first handle on the surface of the crimping block 111, rotate the crimping block 111 into the pit 11, and crimp the outer arc surface into the crimping arc surface 251.

[0062] When the crimping block 111 is screwed into the pit 11, the bottom end of the crimping block 111 crimps the bottom surface of the inner cavity of the pit 11. Compared with the traditional overhead cover plate, the crimping block 111 has a stronger load-bearing capacity. When the functional robot (and other engineering machinery) is crimped on the crimping block 111, it will not cause the crimping block 111 to bend and sink. Therefore, the functional robot does not need to avoid the pit 11, and thus has the largest possible range of motion.

[0063] The low-carbon fully buried sewage treatment system also includes an electrical cabinet, which is fixedly installed on the top of the side wall of the underground space 1 by bolts; the air inlet fan, the exhaust fan, the light sensor, the lighting lamp 6, the first electric blinds, and the second electric blinds are respectively connected to the electrical cabinet through wires and signal lines; the electrical cabinet is connected to the external power supply and the external computer through wires and signal lines, respectively, and the functional robot is connected to the external computer wirelessly, and the computer controls the start and stop and other working states of the air inlet fan, the exhaust fan, the light sensor, the lighting lamp 6, the first electric blinds, the second electric blinds and the functional robot in the present invention.

[0064] The low-carbon fully buried sewage treatment system also includes an intelligent monitoring module, which includes sensors (such as pH sensors, pressure sensors, liquid level sensors, oxygen content sensors, ammonia content sensors, nitrogen content sensors, etc., which are used to monitor various parameters in the sewage treatment process) and cameras arranged in the underground space. The camera is equipped with a night vision component, a heat source monitoring component, and a voiceprint recognition component. The sensor and the camera are respectively connected to the electrical cabinet through wires and signal lines, and the peripheral computer is arranged in the ground control room. The monitoring personnel can evaluate the operation of each process section of the sewage treatment in the ground control room through the data information collected by the intelligent monitoring module. When an abnormal gas parameter is detected in a certain underground space 1 (for example, the oxygen content is lower than the threshold value, and the ammonia content is higher than the threshold value), the active ventilation component is started to accelerate the ventilation, and the inspection robot drives to the underground space 1 for data collection or collaborative operation. When an abnormal light parameter is detected in a certain underground space 1, the active lighting component is started to fill the light, and the inspection robot drives to the underground space 1 for data collection or collaborative operation. A lighting window is provided on the top surface of the underground space 1 for natural light irradiation. When there is sufficient natural light (monitored by a light sensor), the camera enters low-power mode and only enables the color recognition function; when there is insufficient natural light, the built-in night vision component (i.e., infrared fill light component) is activated.

[0065] The underground space 1 is a basement.

[0066] The present invention has a simple structure and reliable functions. When no one is in the underground space 1, an unmanned operation and maintenance module is used to maintain the operation of the low-carbon fully buried sewage treatment system, and passive ventilation components and passive lighting components are used to ventilate and illuminate the underground space 1, which has low energy consumption. When users enter the underground space 1, active ventilation components and active lighting components are used to enhance ventilation intensity and lighting intensity, ensure the life safety of users and provide a good field of vision, thereby facilitating users' underground operations.
