As shown in Figure 1-3: a self-starting anti-fall early warning inspection well seat, which is fixed in a cylindrical inspection well bore, a manhole cover is installed above the inspection well, and the well seat is 1 is located between the wellbore and the manhole cover of the inspection well. The well seat 1 is cylindrical and is installed on the wellbore of the inspection well. It also includes a warning device 2 and an anti-falling net 3. The warning device 2 is installed on the well seat. 1, and the warning device 2 is arranged close to the inner wall of the wellbore of the inspection well, and the anti-falling net 3 is installed at the bottom of the well seat 1.

The well base 1 includes a well base support 1.1, a connecting rod 1.2, a fixed support 1.3, a hook 1.4 and an axial positioning clamp 1.5. The well base support 1.1 is installed on the top of the inspection well bore. The connecting rod 1.2 is located at the lower end of the well seat support 1.1, the fixed support 1.3 is installed at the bottom end of the connecting rod 1.2, the bottom end of the connecting rod 1.2 is installed with a hook 1.4, and the axial positioning card There are at least two hoops 1.5, one is mounted on the well seat support 1.1 and the other is mounted on the connecting rod 1.2. The well base 1 is installed on the wellbore of the inspection well, wherein the connecting rod 1.2 is arranged close to the wall of the wellbore of the inspection well. The seat support 1.1 is fixed together with the inspection well shaft, and the well seat 1 is mainly fixed on the inspection well shaft and provides a support structure for the warning device 2 at the same time.

The warning device 2 includes a compression spring 2.1, a hydraulic telescopic rod 2.2, a torsion spring 2.3 and a warning sign 2.4. The hydraulic telescopic rod 2.2 is provided with a torsion spring 2.3 at the top and a compression spring 2.1 at the bottom. The torsion spring 2.3 A warning sign 2.4 is installed on the top, and the bottom of the compression spring 2.1 is fixed on the fixed support 1.3. The warning device 2 is mainly used to warn passers-by. When the manhole cover rolls over, the warning sign 2.4 sticks out of the ground to remind people to avoid falling into the inspection well. , the anti-falling net 3 installed in the inspection well shaft can also prevent personnel from being injured.

The upper and lower axial positioning clamps 1.5 are respectively used for fixing the upper and lower ends of the hydraulic telescopic rod 2.2. At least two axial positioning clamps 1.5 are respectively fixed on the upper and lower ends of the hydraulic telescopic rod 2.2, which can ensure the overall stability of the hydraulic telescopic rod 2.2 and ensure that it will not tilt at will.

The self-starting type anti-fall early warning inspection well seat of the utility model comprises a well seat 1, a warning device 2 and an anti-fall net 3; wherein: the well seat 1 is composed of a manhole cover support 1.1, a connecting rod 1.2, It consists of a fixed support 1.3, a hook 1.4 and an axial positioning clamp 1.5. The manhole cover support 1.1 is the connection transition module between the wellbore and the manhole cover in the inspection well, which is consistent with the structure and size of the conventional inspection well seat; the connecting rod 1.2 is mainly used to fix the connection between the fixed support 1.3 and the manhole cover support 1.1. The fixed support 1.3 is mainly used for the connection and fixation of the warning device 2 and the anti-falling net 3 .
