Technical Field

[0001] The utility model relates to a protective device for a sewer well, in particular to a sewer well cover damage warning and protection device. Background Art

[0002] In urban infrastructure projects, the city's drainage system is very important, and a manhole is a structure that drains water from the road into the sewer. The manhole is equipped with a manhole cover. The manhole cover can not only filter out larger debris, but also allow the manhole cover to be opened to work inside the manhole.

[0003] Since a manhole cover is provided on the sewer, there is a situation where the manhole cover is separated from the sewer, so that the wellhead of the sewer is in an open state.

[0004] On urban roads, the openings of manholes are in an open state, which is a very dangerous situation, especially at night when the ambient light is relatively dim. Pedestrians or vehicles can easily fall into the manholes if they are not careful. Utility Model Content

[0037] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0038] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] Example:

[0041] See also Figure 1 、 Figure 2 and Figure 3 This embodiment discloses a sewer manhole cover damage warning and protection device, comprising a telescopic assembly 10, a warning light 20, an alarm (not shown), a push-button switch 30, and a protective net 40. The telescopic assembly 10, warning light 20, alarm, push-button switch 30, and protective net 40 are all disposed within a sewer manhole 50, with the warning light 20 disposed on the telescopic assembly 10. The push-button switch 30 is electrically connected to the warning light 20 and the alarm via wires.

[0042] Specifically, the telescopic assembly 10 is positioned within the manhole 50, near the manhole's opening. The telescopic assembly 10 is adjustable in length and can reciprocate vertically. The warning light 20 is mounted on the top of the telescopic assembly 10. When the telescopic assembly 10 is extended, it can be extended beyond the manhole's opening.

[0043] The alarm is installed on the inner wall of the sewer manhole 50 to sound an alarm. The push switch 30 is also set on the inner wall of the sewer manhole 50 and close to the wellhead of the sewer manhole 50. In this application, the push switch 30 is a normally closed switch. When the manhole cover is installed on the wellhead of the sewer manhole 50, the manhole cover triggers the push switch 30, causing the contacts in the push switch 30 to separate.

[0044] The protection net 40 is disposed inside the sewer shaft 50 , and the protection net 40 is intercepted inside the sewer shaft 50 . Meanwhile, the protection net 40 is located below the telescopic assembly 10 , the push switch 30 and the alarm.

[0045] In this embodiment, a telescopic assembly 10 is disposed within a manhole 50, and a warning light 20 is disposed on top of the telescopic assembly 10. When the manhole cover is closed on the manhole 50, the compression assembly is compressed, concealing the warning light 20 within the manhole 50. Simultaneously, the manhole cover also presses on the switch 30, de-energizing the warning light 20 and the alarm.

[0046] When the manhole cover on the sewer well 50 is opened, the push switch 30 pops up, and the alarm and the warning light 20 are energized. The alarm sounds an alarm, and the warning light 20 emits a warning light.

[0047] Furthermore, after the manhole cover is opened, the telescopic assembly 10 automatically pops up and extends its top out of the manhole, thereby supporting the warning light 20 outside the manhole.

[0048] In this technical solution, by providing the warning light 20 and the siren, the purpose of reminding the passing pedestrians and vehicles to pay attention to safety is achieved, thereby reducing the probability of safety accidents.

[0049] In one specific embodiment:

[0050] The telescopic assembly 10 includes a support rod 11, a first connecting rod 12, a second connecting rod 13 and a spring 14. Specifically, the support rod 11 is arranged in a horizontal direction, and one end of the support rod 11 is fixedly arranged on the inner wall of the sewer well 50.

[0051] One end of the first connecting rod 12 is rotatably connected to the other end of the support rod 11, and the middle part of the first connecting rod 12 is rotatably connected to the middle part of the second connecting rod 13. One end of the spring 14 is fixedly set on the end of the support rod 11 away from the inner wall of the sewer well 50, and the other end of the spring 14 is fixedly set at one end of the second connecting rod 13. At this time, the other end of the second connecting rod 13 is its top end.

[0052] The warning light 20 is arranged on an end of the first connecting rod 12 away from the support rod 11 , or on an end of the second connecting rod 13 away from the spring 14 .

[0053] In this embodiment, when the manhole cover is pressed against the top ends of the first and second connecting rods 12, 13, they retract into the manhole 50, driving the warning light 20 to retract into the manhole 50. At this point, the spring 14 is pulled. When the manhole cover is opened, the contracting force of the spring 14 causes the bottom end of the second connecting rod 13 to move closer to the support rod 11, allowing the first and second connecting rods 12, 13 to support the warning light 20 outside the manhole 50.

[0054] Preferably, a stopper rod is provided at the end of the support rod 11 away from the inner wall of the manhole 50. The length of the stopper rod is aligned with the length of the support rod 11, and the end of the second connecting rod 13 connected to the spring 14 is slidably mounted on the stopper rod. In addition, the first connecting rod 12 is rotatably connected to the side of the support rod 11, so that the rotation axis of the first connecting rod 12 on the support rod 11 extends horizontally.

[0055] In this technical solution, a limit rod is provided to limit the movement path of the second connecting rod 13, and the rotation axis of the first connecting rod 12 is set in the horizontal direction, so that the first connecting rod 12 and the second connecting rod 13 can only rotate in the vertical plane.

[0056] In another specific embodiment:

[0057] The first connecting rod 12 and the second connecting rod 13 constitute an X member, and a plurality of X members are arranged in sequence. Specifically, in two adjacent X members, the first connecting rod 12 of one X member is rotatably connected to the second connecting rod 13 of the other X member.

[0058] The warning light 20 is arranged on the topmost X member, and multiple warning lights 20 can also be arranged on the X member.

[0059] In this embodiment, by providing a plurality of X members, the top of the telescopic assembly 10 can be raised to a higher height, thereby achieving a better reminder effect.

[0060] Preferably, all the warning lights 20 are in a long strip shape, and the outer tubes of the warning lights 20 are all red, so that the warning lights 20 emit a more eye-catching red light.

[0061] In another specific embodiment:

[0062] The alarm includes a speaker and a battery. The speaker, push switch 30 and battery are connected in series. The warning light 20, push switch 30 and battery are connected in series. In addition, the alarm and warning light 20 are waterproof.

[0063] In this embodiment, the horn and the warning light 20 are respectively connected in series with the push switch 30 and the battery, so that when the push switch 30 is triggered, the horn and the warning light 20 can be directly started at the same time.

[0064] Since it is a sewer well 50, in order to prevent water from entering various electronic components, the alarm and the warning light 20 are both waterproofed.

[0065] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
