Problems solved by technology

Under the influence of heavy rains, the drainage of urban sewer pipes is limited, and it is easy to cause water flow on the road surface. The water flows through the assembly and washes away the well cover, resulting in no protection at the well head. However, the well head is blocked by rain, so it is difficult to find the position of the well head, which is easy to cause pedestrians to fall In the wellhead, pedestrians were injured

Embodiment Construction

[0018] The present invention will be further elaborated below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1-6 As shown in the figure, an early warning protection device for the loss of municipal manhole covers includes an annular device 1, a base cone 2, a first-level telescopic cylinder 3, a second-level telescopic cylinder 4, a spring 5, an annular connecting rod 6, and a support device 7. It is characterized in that: a plurality of base cones 2 are fixed at an equal angle on the top surface of the ring device 1, and a first-stage telescopic cylinder 3 and a second-stage telescopic cylinder 4 are slidably connected in the base cone 2 in sequence. The shape cylinder 2, the first-level telescopic cylinder 3 and the second-level telescopic cylinder 4 are stretched and contracted by the spring 5, and the top of the outer wall of the base conical cylinder 2, the first-level telescopic cylinder 3, and the second-level telescopic cyli...

Abstract

The invention discloses a municipal well lid loss early warning protection device which comprises an annular device, base conical barrels, a first-stage telescopic barrel, a second-stage telescopic barrel, a spring, an annular connecting rod and a supporting device. A first-stage telescopic cylinder and a second-stage telescopic cylinder are sequentially connected into the base conical cylinder in a sliding mode, the interiors of the base conical cylinder, the first-stage telescopic cylinder and the second-stage telescopic cylinder stretch out and draw back through springs, and horizontal annular connecting rods are fixed to the tops of the outer walls of the base conical cylinder, the first-stage telescopic cylinder and the second-stage telescopic cylinder. A plurality of supporting devices are installed on the inner circumference of the annular device. The device plays a role in warning, prevents pedestrians from falling into a wellhead, prevents foreign matters from being washed into the wellhead by rainwater in cooperation with the annular connecting rod, and can also play a role in blocking the foreign matters and preventing the wellhead from being blocked.

Description

technical field [0001] The invention relates to a protection device, in particular to an early warning protection device for the loss of municipal manhole covers. Background technique [0002] Urban drainage manhole covers are drained through underground pipes to avoid the accumulation of rainwater on the road. Under the influence of heavy rain, the drainage capacity of urban sewer pipes is limited, and it is easy to form water flow on the road surface. The water flows through the assembly and washes away the manhole cover, resulting in the phenomenon of no protection at the wellhead, and the wellhead is blocked by rainwater. It is difficult to find the location of the wellhead, which is easy to cause pedestrians to fall In the wellhead, pedestrians were injured. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an early warning protection device for the loss of municipal manhole covers to solve the above-mentioned technical problems. ...
