Description

An anti-theft manhole cover

technical field

The utility model relates to an inspection well cover, in particular to an anti-theft inspection well cover, which belongs to the field of municipal public facilities.

Background technique

In urban construction, underground pipelines are indispensable, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet leading to the ground every other section, and the pipeline from the pipeline to the ground This section is called the inspection well, and the mouth of the inspection well is usually flush with the ground, so a cover is needed to cover the inspection well, which is called the inspection well cover. Manhole covers are usually made of reinforced concrete, metal, reinforced plastics and other materials, and their shapes are based on circles and squares. Used to cover roads or deep wells in homes to prevent people or objects from falling.

The traditional manhole cover is still used on many urban roads. The traditional manhole cover is simply placed on the top of the sewer pipe and deep well, so there is often a problem of being stolen. If the manhole cover is stolen by criminals, the sewer pipe , The deep well is exposed on the road, and there is a great potential safety hazard. For example, the patent No. 201410050603.2 discloses a manhole cover, which detects the presence or absence of the manhole cover through a pressure-sensitive sensor. When the gushing water washes away the inspection well cover, the washed away inspection well cover drives the drawstring to tear off the sealing cover of the sealing warning device, and the warning device inflates and floats to the liquid surface, reminding pedestrians that the inspection well cover under the liquid surface is washed away, ensuring pedestrian safety. But the production cost is higher, and still can not effectively prevent the well cover from being stolen. In order to solve the problem of manhole cover being stolen, the utility model patent with the patent application number of 99237459.6 discloses a kind of anti-theft manhole cover, which adopts a hanging basket structure and realizes anti-theft by soaking in water under its own weight, but the overall structure is too large and requires The hanger is lifted, it is inconvenient to use, and the manhole cover is not anti-corrosion and other defects.

detailed description

In Fig. 1-2, a kind of anti-theft manhole cover comprises manhole cover 1, outer frame 2, metal loam cake 6, and the outer wall of manhole cover 1, outer frame 2, metal loam cake 6 is all coated with protective paint protective layer, through protection The protective effect of the paint protection layer can effectively prevent the manhole cover 1, the outer frame 2, and the metal upper cover 6 from being exposed to the sun and rain and corroded. Drainage grooves 3 are arranged at equal intervals on the outer frame 2 to effectively discharge accumulated water and prevent the manhole cover from being corroded. The metal upper cover 6 is provided with an exhaust net 7 to effectively discharge the pipeline gas. The first holder 4 and the second holder 8 are respectively arranged on the two ends of the metal upper cover 6 along the central horizontal axis, the first escutcheon 5 is installed in the middle of the first holder 4, and the first clamping plate is arranged below the first escutcheon 5 11. The first locking cylinder 10 is arranged inside the first clamping plate 11, and the first clamping post 12 is provided on one side of the first clamping plate 11, and the first clamping plate 11 and the first clamping post 12 are in a concave fixed structure. The second escutcheon 9 is installed in the middle of the second retainer 8, the second escutcheon 9 below is provided with the second clamping plate 15, the second clamping plate 15 inside is provided with the second lock core 14, and the second clamping plate 15 side is provided with the second clamping plate 15. The second clamping post 13, the second clamping plate 15 and the second clamping post 13 are in a concave fixed structure. The first clamping plate 11 , the second clamping plate 15 and the outer frame 2 are in a rotating connection structure. The manhole cover 1 is clamped above the sewer pipe 16 through the first clamping plate 11 and the first clamping column 12 and the second clamping plate 15 and the second clamping column 13 of the concave fixed structure, thereby preventing theft. The first clamping column 12, the second clamping column 13 and the manhole cover 1 are fixed by welding, and the first clamping column 12 and the second clamping column 13 are vertically connected with the manhole cover 1 to increase the tightness of the internal structure connection of the device.

The use process of an anti-theft manhole cover: insert a specific key into the first lock core 10 and the second lock core 14, and turn the key to drive the first clamping plate 11 and the second clamping plate 15 to rotate, so that the first clamping column 12 and the second clamping column 12 are rotated. The clamping posts 13 are stuck respectively under the first clamping plate 11 and the second clamping plate 15 to complete the installation of the inspection shaft cover 1. Due to the concave clamping structure of the clamping plate and the clamping post, the inspection shaft cover 1 is effectively prevented from being stolen. When the inspection shaft cover 1 needs to be opened, the first clamping plate 11 and the second clamping plate 15 are rotated in the opposite direction by the key in the same way to open the inspection shaft cover 1 .
