Description

Technical Field

[0001] This utility model relates to the field of manhole covers, and in particular to a safety manhole cover. 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 are removed from manholes for maintenance, emergency drainage, theft, or other reasons. Although some smart manhole covers integrate detection modules to detect whether the cover is open and allow for real-time monitoring, the response from management departments is somewhat delayed, leaving pedestrians and vehicles passing near manholes still at risk. Traffic cones are used to warn pedestrians in areas with exposed manholes; however, their warning function relies on light reflection, and their effectiveness is limited in poorly lit environments. Therefore, a safe manhole cover is urgently needed to address these issues. Utility Model Content

[0022] Figure 1 This is a structural schematic diagram of a safety manhole cover in its first state;

[0023] Figure 2 This is a structural schematic diagram of a safety manhole cover in its second state;

[0024] Figure 3 An exploded view of a type of safety manhole cover;

[0025] Figure 4 for Figure 3 A magnified view of a portion of region A in the middle. Detailed Implementation

[0026] Reference Figures 1 to 4 A safety manhole cover includes a manhole base 10, a light source assembly 20, a manhole cover 30, an elastic component 40, a solar panel 50, a storage battery 60, and a control board 70.

[0027] The well base 10 is provided with a first receiving groove 11 and a second receiving groove 12 with an opening at the top, and a number of clearance grooves 13 communicating with the first receiving groove 11 are provided on the inner side wall of the well base 10.

[0028] The light source assembly 20 is disposed in the first receiving groove 11 and has a plurality of pressure plates 21 extending into the clearance groove 13 thereon;

[0029] The manhole cover 30 is supported on the manhole base 10 and pressed against the pressure plate 21;

[0030] The elastic component 40 is disposed in the first receiving groove 11 and abuts against the light source assembly 20 to provide an upward thrust;

[0031] The solar panel 50, the battery 60 and the control board 70 are disposed in the second receiving groove 12. The control board 70 is electrically connected to the solar panel 50, the battery 60 and the light source assembly 20.

[0032] When the manhole cover 30 is supported on the manhole base 10, it can push the light source assembly 20 to be fully housed in the first receiving groove 11, or when the manhole cover 30 is separated from the manhole base 10, the light source assembly 20 can extend at least partially out of the first receiving groove 11 under the action of the elastic component 40.

[0033] In this invention, during assembly, the light source assembly 20 is first connected to the elastic component 40, and then the elastic component 40 is fixedly connected to the bottom surface of the first receiving groove 11, so that the pressure plate 21 on the light source assembly 20 extends into the clearance groove 13 on the well base 10. Then, the solar panel 50, the battery 60, and the control board 70 are installed in the second receiving groove 12. In some embodiments, the side wall of the well base 10 is provided with mounting holes 16 communicating with the first receiving groove 11 and the second receiving groove 12. The lead wire of the light source assembly 20 passes through the mounting hole 16 and extends into the second receiving groove 12, communicating with the control board 70. The control board 70 is connected to the solar panel 50, which can control the state of the light source component 20. The solar panel 50 can receive sunlight and convert it into electrical energy to charge the battery 60 or directly power the control board 70. When the ambient light is low, the battery 60 powers the control board 70. In a further embodiment, a detection device electrically connected to the control board 70 is provided in the mounting hole 16. As a preferred embodiment of the detection device, the detection device is set as an infrared sensor, which can detect the position of the light source component 20. Finally, the manhole cover 30 is placed on the manhole base 10 and pressed against the pressure plate 21.

[0034] When in use, when the manhole cover 30 is supported on the manhole base 10, the light source assembly 20 will move downward by pushing the pressure plate 21. At this time, the detection device detects and generates a first signal, and the control board 70 determines that the manhole cover 30 is normally installed on the manhole base 20. When the manhole cover 30 is removed from the manhole base 10, the light source assembly 20 will move upward under the pushing action of the elastic component 40. At this time, the detection device detects and generates a second signal, and the control board 70 determines that the manhole cover 30 has been removed, thereby enabling the light source assembly 20 to light up. Since the light source assembly 20 is pushed to extend at least partially outside the first receiving groove 11, the light emitted by the light source assembly 20 can spread in all directions, serving as a light warning to pedestrians and motor vehicles.

[0035] Reference Figures 1-4 In some embodiments, a safety manhole cover also includes several limiting plates 82 connected to the manhole base 10 via a detachable structure 81 and enclosing the upper end of the clearance groove 13. As a preferred embodiment of the detachable structure 81, the detachable structure 81 is configured as a bolt connection structure. The limiting plates 82 limit the movement stroke of the light source assembly 20 and prevent the light source assembly 20 from being maliciously disassembled.

[0036] Reference Figures 3-4 In some embodiments, a first drain outlet 14 communicating with the first receiving tank 11 is provided on the inner side wall of the well base 10. The first drain outlet 14 allows sewage that has seeped into the first receiving tank 11 to be discharged into the well channel through the first drain outlet 14, thereby preventing sewage from accumulating in the first receiving tank 11.

[0037] Reference Figures 3-4 In some embodiments, the bottom surface of the first receiving groove 11 is provided with a mounting groove 15, one end of the elastic component 40 is fixedly connected to the bottom surface of the mounting groove 15, and the other end of the elastic component 40 is fixedly connected to the light source component 20.

[0038] Reference Figures 3-4 In some embodiments, the elastic component 40 includes a plurality of springs 41 evenly distributed within the first receiving groove 11.

[0039] Reference Figures 1-4 In some embodiments, the manhole cover 30 is provided with a plurality of vertically connected second drainage outlets 31, which can meet the daily drainage function under normal conditions.

[0040] Reference Figures 1-4 In some embodiments, the solar panel 50 is covered with a light-transmitting tempered glass plate 90. The tempered glass plate 90 not only protects the solar panel 50 but also does not affect the solar panel 50's reception of sunlight.

[0041] The advantages of this utility model are: the above structure can determine that the manhole cover and the manhole seat are separated when the light source component is detected to extend outside the first receiving groove, and then light up the light source component as a light warning. It can play a very good safety warning role in poor ambient lighting conditions, reduce safety risks, and has very good practicality.

[0042] 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.
