DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 What is shown is a front view schematic diagram of a manhole cover in an embodiment; Figure 2 It is shown that Figure 1 AA cross-sectional structure diagram; Figure 3 Shown is a schematic structural diagram of an adjustment plate in an embodiment.

[0027] The device includes:

[0028] Base 10;

[0029] A cover 20, the cover 20 is at the opening end of the base 10;

[0030] The drainage structure 30 includes a filter hole 32 that penetrates the cover body 20 and has a built-in filter, and an adjustment plate 33 that is rotatably disposed at the bottom end of the cover body 20;

[0031] The adjusting plate 33 rotates to a position where the filter holes 32 are completely covered, and the filter holes 32 are closed, and the cover body 20 does not have a drainage function;

[0032] When the adjusting plate 33 is rotated to a position where the filter holes 32 are partially or completely blocked, a part of or all of the filter holes 32 are opened, and the cover body 20 has a drainage function.

[0033] To facilitate the inspection and maintenance of the pipeline, the cover 20 is detachably arranged at the open end of the base 10, and specifically, can be hingedly arranged with the base 10;

[0034] The adjustable drainage structure 30 can control the drainage volume of the filter holes 32 according to actual conditions. When there is no drainage demand, the filter holes 32 are closed to prevent the sewage gas in the sewer from overflowing and polluting the surrounding environment; when there is a drainage demand, the filter holes 32 are opened, and the drainage volume of the cover body 20 is adjusted according to the specific drainage demand, thereby achieving flexible drainage.

[0035] The drainage structure 30 also includes a rain sensor 31, a controller and a driver 34. The rain sensor 31 is embedded in the top of the cover body 20, and the driver 34 is arranged at the bottom of the cover body 20 and its output end is fixedly connected to the adjustment plate 33. There are signal connections between the rain sensor 31 and the controller, and between the controller and the driver 34.

[0036] Specifically, the controller is arranged inside the cover body 20 (not shown in the figure), the rain sensor 31 can sense the amount of rainfall and transmit the information to the controller, and the controller controls the operation of the driving member 34 by analyzing the information. The driving member 34 drives the adjustment plate 33 to rotate a certain angle, so that the filter hole 32 of the adjustment plate 33 is opened or closed, thereby realizing automatic adjustment of the drainage amount.

[0037] The adjustment plate 33 includes an adjustment portion 331 and a mounting portion 332. The adjustment portion 331 is movably fitted with the bottom end of the cover body 20. The shape of the adjustment portion 331 matches the shape of the filter hole 32. The mounting portion 332 is provided with a recessed mounting groove. The driving member 34 is arranged at a position corresponding to the mounting groove at the bottom end of the cover body 20, and the output end of the driving member 34 is fixedly connected to the mounting portion 332. The driving member 34 is a motor.

[0038] The filter holes 32 are opened and closed by the correspondence and misalignment of the adjustment portion 331 and the filter holes 32. Specifically, in this embodiment, the adjustment portion 331 and the filter holes 32 are both arranged in an arc shape and are arranged symmetrically.

[0039] When the adjusting portion 331 is rotated to a state where it is completely misaligned with the filter hole 32, the adjusting portion 331 does not block the filter hole 32. At this time, the water flow can smoothly pass through the entire filter hole 32 into the sewer, which is suitable for when the drainage demand is large, such as heavy rainfall or water accumulation; when the drainage demand is small, such as rainy weather but small rainfall, the adjusting portion 331 is controlled to be partially misaligned with the filter hole 32, and the water flow can enter the sewer from the opened filter hole 32; when there is no drainage demand, such as when the weather is clear, in order to prevent the sewage gas in the sewer from overflowing and polluting the surrounding environment, the adjusting portion 331 is controlled to be in a state where it corresponds to and overlaps with the filter hole 32, so that the filter hole 32 can be closed.

[0040] The amount of rainwater mentioned in this embodiment is large or small, which is divided and defined by setting a numerical range, and the specific numerical range is determined according to the actual situation.

[0041] The top of the cover body 20 is provided with an embedding groove matching the shape of the rain sensor 31. The rain sensor 31 is arranged in the embedding groove and its top end surface does not exceed the top end surface of the cover body 20.

[0042] The bottom end of the rain sensor 31 embedded in the groove is also provided with an elastic member 311;

[0043] The rain sensor 31 is installed in the embedding groove by the elastic member 311, so that the rain sensor 31 can be protected. When pedestrians or vehicles continue to pass by the top of the cover body 20, under normal circumstances, since the top end surface of the rain sensor 31 does not exceed the top end surface of the cover body 20, the rain sensor 31 will not be subjected to a large impact pressure. Even if it is pressurized, the rain sensor 31 will sink into the embedding groove under the action of the elastic member 311 to avoid damage, and it will recover after the external force disappears to avoid being stuck in the embedding groove all the time and causing water accumulation in the embedding groove.

[0044] A connecting hole 312 connecting the embedded groove and the filter hole 32 is also provided inside the cover body 20. The connecting hole 312 is inclined and one end close to the filter hole 32 is lower than the other end. The connecting hole 312 can further avoid water accumulation in the embedded groove. Even if rainwater enters the embedded groove from the gap, it will be discharged to the filter hole 32 through the inclined connecting hole 312, and further discharged into the sewer.

[0045] An ultrasonic sensor 40 is also provided at the bottom end of the regulating plate 33; the ultrasonic sensor 40 is used to monitor the liquid level, and the liquid level height is determined by measuring the distance from the ultrasonic wave to the liquid surface and the distance from the liquid surface to the sensor, so as to realize real-time monitoring of changes in the sewer water surface and transmit the information to the working end, so that the staff can promptly check whether the sewer is blocked, and make decisions on whether the sewer needs to be expanded based on long-term statistical data.

[0046] The top of the cover 20 is also inlaid with a warning piece 50. The warning piece 50 can be an LED light bar for lighting at night. The LED light bar has a high brightness and can be clearly seen at night or in low visibility conditions, thereby improving the recognition of pedestrians and vehicles. The warning piece 50 can also be a fluorescent light strip that can serve as a reminder at night. After the cover 20 is accidentally damaged, the warning piece 50 can serve as a warning at night.

[0047] Working principle: The device realizes flexible drainage of the cover body 20 through the drainage structure 30. The adjustment process is as follows: After the rain sensor 31 senses the amount of rainfall, the information is transmitted to the controller. The controller controls the operation of the driving member 34 by analyzing the information. When the rain sensor 31 senses that the rainfall is large, the driving member 34 drives the adjustment part 331 of the adjustment plate 33 to rotate to a state where it is completely misaligned with the filter hole 32, that is, the adjustment part 331 does not block the filter hole 32, and the water flow can smoothly pass through the entire filter hole 32. The filter holes 32 enter the sewer to achieve rapid drainage; when the rain sensor 31 senses a small amount of rainfall, the driving member 34 drives the adjusting portion 331 of the adjusting plate 33 to rotate to a state partially offset from the filter holes 32, and at this time, the water flow can enter the sewer from the opened filter holes 32; when the rain sensor 31 does not sense raindrops, the driving member 34 drives the adjusting portion 331 of the adjusting plate 33 to rotate to a state corresponding to the filter holes 32, so that the filter holes 32 can be closed, effectively preventing the sewage gas in the sewer from overflowing.

[0048] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
