It is hereby declared that the up, down, left, right, front, back, inner and outer directions appearing or about to appear in the present application in the text are based on the drawings of the present application, and are not specific limitations on the present application.

[0027] Example 1

[0028] An intelligent well lid with the flood discharge function, as shown in Figures 1-7 , comprises a sewer 1 and a well lid 2; the sewer 1 is provided with the well lid 2; the well lid 2 is provided with four drainage holes 2002;

[0029] The manhole cover 2 is provided with the rain amount monitor 108 for monitoring rainfall.

[0030] In order to detect the water level in the water containing frame 103 in real time, the water containing frame 103 is provided with a water level sensor.

[0031] The manhole cover 2 is provided with the rain amount monitor 108 for monitoring rainfall.

[0032] In order to reduce the risk of the rain amount monitor 108 being damaged by vehicles and pedestrians, there is a gap between the upper side of the rain amount monitor 108 and the upper side of the manhole cover 2.

[0033] The manhole cover 2 is provided with the rain amount monitor 108 for monitoring rainfall.

[0034] The manhole cover 2 is provided with the rain amount monitor 108 for monitoring rainfall.

[0035] In order to facilitate the storage of the interception net 106, the interception net 106 is provided in a foldable manner.

[0036] The connecting plate 201 and the arc-shaped plug plate 202 are further included; four connecting plates 201 are fixedly connected to the annular isolation frame 105; one arc-shaped plug plate 202 is connected to each connecting plate 201; four water outlet grooves 10301 are formed in the water containing frame 103; four movable grooves 10303 are formed in the water containing frame 103; the water outlet groove 10301 is communicated with the corresponding movable groove 10303, and the arc-shaped plug plate 202 is movably arranged in the movable groove 10303 to block the water outlet groove 10301.

[0037] In order to facilitate the discharge of the sediment and impurities in the water containing frame 103 through the water outlet groove 10301, the inner bottom surface of the water containing frame 103 is arranged in an inclined shape towards the water outlet groove 10301.

[0038] The working process of the intelligent well cover 2 with the flood discharge function is as follows:

[0039] It should be noted that the water inlet of the water pump 10302 is communicated with the sewage in the sewer 1 through a hose and a filtering device; as shown in the figure, the annular isolation frame 105 is located inside the water containing frame 103, and a gap is formed between the lower side of the annular isolation frame 105 and the inner bottom surface of the water containing frame 103; the drain hole 2002 is directly opposite the inside of the annular isolation frame 105; Figure 3

[0040] In use, the filtered sewage is pre-discharged into the water containing frame 103 by the water pump 10302 until the water containing frame 103 is filled with water to submerge the lower part of the annular isolation frame 105, and a barrier is formed between the well cover 2 and the sewer 1 by the water, so that when the unextinguished cigarette butt or the burning object floating from the outside falls into the sewer 1 through the drain hole 2002 of the well cover 2, the burning object will fall into the water containing frame 103 and be extinguished by the water in the water containing frame 103, thereby avoiding the burning object falling into the sewer 1 to ignite the methane gas in the sewer 1 and causing an explosion; by using water as an isolation barrier, the drain hole 2002 is directly closed, the water on the road surface can be normally discharged, and the drain hole 2002 needs to be repeatedly controlled to open and close when water needs to be discharged; it is specified that the water discharge process is that the water from the outside flows into the water containing frame 103 through the drain hole 2002 and then overflows into the sewer 1 through the water containing frame 103; it is specified that the methane gas discharge process in the sewer 1 is that the methane gas first enters the water containing frame 103 through the gap between the water containing frame 103 and the well cover 2, and then is discharged into the air through the drain hole 2002 after being blocked by the annular isolation frame 105 and the water; it should be noted that the methane gas discharged into the air will be mixed with the air and dispersed, and the concentration is low and cannot be ignited by an open flame.

[0041] ​Considering that the amount of biogas discharged to the outside through the drain hole 2002 by water is small, a large amount of biogas accumulates below the well lid 2; therefore, by arranging a biogas concentration sensor on the bottom surface of the water retaining frame 103, the biogas concentration and pressure are monitored by the biogas concentration sensor, and when the amount and pressure of biogas in the sewer 1 are monitored to be too large, the biogas concentration sensor feeds back a signal to the background to inform the staff that the biogas in the sewer 1 needs to be treated, so as to avoid the amount and pressure of biogas in the sewer 1 being too large, which may cause the well lid 2 to be lifted up and cause a safety hazard to pedestrians and vehicles.

[0042] Further, the water level in the water retaining frame 103 is monitored in real time by the water level sensor on the water retaining frame 103, and when the water level in the water retaining frame 103 is about to be lower than the lower part of the annular isolation frame 105 due to evaporation, the water level sensor sends a signal to control the water pump 10302 to discharge the filtered sewage into the water retaining frame 103, so as to ensure that there is enough water in the water retaining frame 103 to isolate the combustible material.

[0043] Further, when the rainfall monitor 108 on the well lid 2 detects rainfall, the rainfall monitor 108 controls the first electric push rod 101 to drive the mounting rod 102 and the water retaining frame 103 to descend, so that the water retaining frame 103 is away from the annular isolation frame 105, so as to increase the distance between the water retaining frame 103 and the annular isolation frame 105, avoid the annular isolation frame 105 blocking the water flowing from the drain hole 2002 into the water retaining frame 103, so as to ensure the drainage efficiency and ensure that the water inflow and the water outflow are consistent; further, when the first electric push rod 101 drives the mounting rod 102 and the water retaining frame 103 to descend, the arc-shaped plug plate 202 will be away from the water retaining frame 103, so that the water outlet groove 10301 is opened, so as to further ensure the drainage efficiency.

[0044] It is explained here that during the long-term use of the well lid 2, the small impurities such as silt carried by water will enter the water retaining frame 103 through the drain hole 2002 on the well lid 2 and deposit, and after the water outlet groove 10301 is opened, the deposited silt impurities will move to the water outlet groove 10301 under the guidance of the inclined bottom surface of the water retaining frame 103, therefore, after the water outlet groove 10301 is opened, the silt impurities in the water retaining frame 103 will be quickly washed away with the water flow, it is noted that most of the silt and other small impurities entering the sewer 1 will be washed away by the water flow in the sewer 1, and will not cause the sewer 1 to be blocked.

[0045] Considering that when the rainfall is large, the drain hole 2002 cannot meet the rainfall, which easily leads to road waterlogging, therefore, a (capacitive, ultrasonic or radar type) liquid level sensor is embedded on the well lid 2 to monitor the distance between the water surface and the well lid 2, and when the water accumulation above the well lid 2 is serious, the liquid level sensor controls the second electric push rod 104 to drive the lifting part 2001 on the well lid 2 and the connected parts to move upward, such as Figure 7As shown, until the lifting part 2001 is higher than the manhole cover 2 (10 cm), the area of the drain outlet is increased, and the flood discharge operation is performed; it is explained that in the process of the rain amount monitor 108 controlling the first electric push rod 101 to drive the installation rod 102 and the water containing frame 103 to descend, and the water containing frame 103 is far away from the annular isolation frame 105, the second electric push rod 104 adaptively pushes the lifting part 2001 on the manhole cover 2 and the connected parts upward, so that the lifting part 2001 and the connected parts are always in the original position and do not move.

[0046] Further, when the lifting part 2001 moves upward, the interception net 106 is also moved upward, and after the lifting part 2001 is higher than the manhole cover 2 (10 cm), the interception net 106 is in a tight state, and then the interception net 106 intercepts the garbage in the water, so as to avoid a large amount of garbage entering the sewer 1 and easily blocking the sewer 1; at the same time, when the flood discharge is performed, the second electric push rod 104 can be controlled to repeatedly rise and fall at regular time, so that the interception net 106 repeatedly contracts and expands, and the garbage intercepted on the interception net 106 is pushed away, thereby ensuring the flow of rainwater.

[0047] Embodiment 2

[0048] On the basis of embodiment 1, as shown in Figures 3-5 It also includes a spring 203; two springs 203 are fixedly connected on each connecting plate 201, and the connecting plate 201 is fixedly connected with the arc-shaped plug plate 202 through the spring 203.

[0049] In order to guide the arc-shaped plug plate 202 to be inserted back into the movable groove 10303, the upper side section of the movable groove 10303 is provided in an inverted eight-shaped manner.

[0050] The surface of the water containing frame 103 and the annular isolation frame 105 will inevitably have pollutants left over in long-term use, thereby breeding bacteria, accelerating the aging of the water containing frame 103 and the annular isolation frame 105, and reducing the service life of the water containing frame 103 and the annular isolation frame 105; therefore, the sanitation worker can pour the powdery cleaning agent into the water containing frame 103 through the drain hole 2002 on the well lid 2 at regular intervals, and the powdery cleaning agent will dissolve in the water in the water containing frame 103 to dissolve the residual pollutants on the water containing frame 103 and the annular isolation frame 105; in addition, during the dissolving process, the mounting rod 102, the water containing frame 103 and the second electric push rod 104 can be driven upward by the first electric push rod 101, and during this process, the lifting part 2001 on the well lid 2 will be adaptively lowered by the extension end of the second electric push rod 104, so that the lifting part 2001 and other parts are in their original positions, and the annular isolation frame 105 is submerged in the water in the water containing frame 103, thereby ensuring the dissolving effect of the residual pollutants on the annular isolation frame 105; it should be noted that after a period of dissolution, the mounting rod 102 and the water containing frame 103 are lowered away from the annular isolation frame 105 by the first electric push rod 101, so that the water in the water containing frame 103 is drained through the water outlet groove 10301.

[0051] It should be noted that because the bottom of the arc-shaped plugboard 202 is in contact with the bottom of the water containing frame 103, the upward movement of the water containing frame 103 is blocked, therefore, the connecting plate 201 is connected to the arc-shaped plugboard 202 through the spring 203, thereby providing a space for movement by the spring 203 when the water containing frame 103 continues to rise, and ensuring the normal upward movement of the water containing frame 103.

[0052] The above embodiments are only preferred embodiments of the present application and are not intended to limit the scope of the present application, therefore, any equivalent changes made according to the content described in the claims of the present application should be included in the scope of the claims of the present application.
