Description

Technical Field

[0001] This utility model relates to the field of manhole covers, and in particular to a manhole cover with a nighttime warning function. Background Technology

[0002] Urban construction involves the design of numerous pipelines, including drainage pipes and cable conduits, along with corresponding drainage outlets and inspection ports, necessitating the installation of manhole covers for concealment. Manhole covers may be removed from manholes for reasons such as maintenance, emergency drainage, or theft. Although some smart manhole covers integrate detection modules to detect whether the cover has been opened and allow for real-time monitoring by the backend, the management department's response is somewhat delayed, leaving pedestrians or vehicles passing by the manholes with certain risks.

[0003] In the prior art, such as the Chinese utility model patent application number 2024231110187, a manhole cover is disclosed that is equipped with a light source component, a sensor, a storage battery, and a solar cell. The light source component can open the power supply path between the storage battery and / or the solar cell and the light source component when the sensor detects that the cover is separated from the manhole base, thereby illuminating the light source component for light warning. However, the light source component in this manhole cover is always lit after the manhole cover is opened, and during the day, due to the good brightness, there is no need for warning, which results in a waste of power. Therefore, there is an urgent need for a manhole cover with a night warning function to solve the above problems. Utility Model Content

[0032] Reference Figures 1 to 5 A manhole cover with nighttime warning function includes a manhole base 10, a body 20, a control board 30, a light source assembly 40, a first sensor 51, a second sensor 52, a storage battery 60, and a solar cell 70.

[0033] Well base 10 is installed at the wellhead;

[0034] The main body 20 is supported on the well base 10;

[0035] The light source assembly 40 is disposed on the inner wall of the well base 10;

[0036] The first sensor 51 is installed on the well base 10 to detect whether the main body 20 is separated from the well base 10;

[0037] The second sensor 52 is installed on the well base 10 and is used to detect ambient brightness;

[0038] A storage battery 60 and a solar cell 70 are mounted on the well base 10;

[0039] The control board 30 is mounted on the well base 10 and is electrically connected to the light source assembly 40, the first sensor 51, the second sensor 52, the storage battery 60, and the solar cell 70.

[0040] The control board 30 can turn on the power supply path between the battery 60 and / or the solar cell 70 and the light source assembly 40 to light up the light source assembly 40 when the first sensor 51 detects that the body 20 is separated from the well base 10 and the second sensor 52 detects that the ambient brightness is less than a preset value.

[0041] In some embodiments of this utility model, an annular mounting groove 13 is provided on the inner sidewall of the well base 10, the light source assembly 40 is disposed in the annular mounting groove 13, and a mounting seat 80 is provided on the outer sidewall of the well base 10, the mounting seat 80 having a cavity 81; and a first mounting hole 11 and a second mounting hole 12 communicating with the cavity 81 are provided on the inner sidewall of the well base 10; during assembly, the light source assembly 40 is first embedded in the annular mounting groove 13, then the first sensor 51 is installed in the first mounting hole 11, the second sensor 52 is installed in the second mounting hole 12, then the control board 30, the battery 60 and the solar cell 70 are disposed in the mounting seat 80, and finally the control board 30 is connected together with the light source assembly 40, the first sensor 51, the second sensor 52, the battery 60 and the solar cell 70.

[0042] In use, when the first sensor 51 detects that the main body 20 is not turned on, it will send a corresponding signal to the control board 30. At this time, regardless of the ambient brightness detected by the second sensor 52, the control board 30 will not open the power supply path between the battery 60 and / or the solar cell 70 and the light source assembly 40, and the light source assembly 40 will not be lit. When the first sensor 51 detects that the main body 20 is turned on, it will send a corresponding signal to the control board 30. The control board 30 then judges the ambient brightness detected by the second sensor 52. At this time, regardless of the ambient brightness detected by the second sensor 52, the control board 30 will not open the power supply path between the battery 60 and / or the solar cell 70 and the light source assembly 40, and the light source assembly 40 will not be lit. If the detected ambient brightness is less than the preset value, it is determined that it is nighttime or the weather is relatively dark. In this case, the control board 30 turns on the power supply path between the battery 60 and / or the solar cell 70 and the light source component 40, so that the light source component 40 is lit. If the ambient brightness detected by the second sensor 52 is greater than the preset value, it is determined that it is daytime or the ambient brightness is good (such as the surrounding street lights). In this case, the control board 30 does not turn on the power supply path between the battery 60 and / or the solar cell 70 and the light source component 40, so the light source component 40 is not lit.

[0043] In some embodiments, a manhole cover with a night warning function also includes a tempered glass plate 90 disposed within a cavity 81 and above a solar cell 70; the tempered glass plate 90 is used to protect the solar cell 70 and also to avoid affecting the solar cell 70's reception of sunlight.

[0044] In some embodiments, a manhole cover with a night warning function further includes a reflective structure 91 disposed on the inner side wall of the manhole base 10; by setting the reflective structure 91 to reflect the light emitted by the light source assembly 40, the illumination range can be improved, and the safety warning effect can be further improved; as a preferred embodiment of the reflective structure 92, the reflective structure 92 is set as a reflective sticker, of course, the reflective structure 92 can also be set as a reflective coating.

[0045] The advantage of this invention is that the above structure enables the light source component to be lit only when the manhole cover is opened and at night or when the ambient light is low, so as to provide a warning to pedestrians or vehicles, avoiding the waste of electricity by lighting it during the day, and thus having very good practicality.

[0046] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
