The following detailed description of specific embodiments of the utility model refers to the accompanying drawings and the detailed description.

The inspection well warning device comprises a warning rod, a spring and an inspection well cover, wherein the inspection well cover 4 is arranged at an inspection well opening, the spring comprises a first spring 2 and a second spring 7, a fixed box 1 is arranged on the inspection well wall, one end of the first spring 2 is fixedly arranged in the fixed box 1, the other end of the first spring 2 is fixedly arranged in the tail part of the warning rod 3, the warning rod 3 is provided with the warning device, and the warning rod 3 is bent through the first spring 2 and the head part of the warning rod is in contact with the inner surface of the inspection well cover 4 to form a limiting structure of the warning rod 3.

In order to ensure better implementation effect, the warning rod 3 comprises a body 31 and an extension rod 5, the first spring 2 is arranged in the tail part of the body 31, the head part of the body 31 is provided with an inclined notch 8, the extension rod 5 is an arc-shaped pipe and is connected with the head part of the body 31 through a pin shaft 6, one end of the second spring 7 is connected with the head part of the body 31, the other end of the second spring 7 is fixed with the inner surface of the extension rod 5, and the bending part of the second spring 7 is positioned in the inclined notch 8, so that the second spring 7 can be normally bent and reset.

The length of the extension bar 5 is smaller than that of the body 31, so that the extension bar 5 cannot collide with a inspection well mouth after the body 31 is erected, and the extension bar 5 can be normally sprung.

The warning device comprises an audible and visual alarm 14 and a communication module 11, an electric box 9 is arranged in the tail part of the warning rod 3, a battery 10 and the communication module 11 connected with the battery 10 are arranged in the electric box 9, and a contact switch 12 is arranged outside the tail part of the warning rod 3; the upper part of the body 31 is provided with a transparent window 13, the inner wall of the body 31 in the transparent window 13 is provided with an audible and visual alarm 14, and the audible and visual alarm 14, the battery 10 and the communication module 11 are connected with a contact switch 12; when the warning rod 3 is sprung, the contact switch 12 is in contact with the wall of the inspection well, and at the moment, the circuit is communicated, the communication module 11 can send a signal to the far end (such as a mobile phone, a computer and the like), and the audible and visual alarm 14 can emit sound and light.

It should be noted that, the electrical box 9 is a sealing structure, and the contact switch 12 is a waterproof type tact switch, such as a tact switch with the model of P65-2_t41su, so that the normal operation of the contact switch 12, the battery 10 and the communication module 11 is fully ensured.
