Abstract
The utility model relates to an underground well safety protection device, which comprises expansion hooks which are fixed below an underground well cover, wherein hanging rings which are adapted to the expansion hooks are arranged on the outer edge of a safety protection screen, the expansion hooks comprises fastening screws, fastening bolts, fastening nuts, limited bulges and fixed hooks, the fastening bolts and the fastening nuts are sleeved on the fastening screws, and the limited bulges are arranged on the two ends of the fastening screws. The safety protection screen is fixedly arranged below the underground well cover through the expansion hooks, and even though the underground well cover is stolen or lost to enable people to fall into a well, people can not be injured or dead. The underground well safety protection device is fixed in a well wall under a wellhead 10-150cm through a plurality of expansion hooks which are made from metal materials such as stainless steel and stainless iron and the like, and the safety protection screen can not loose and fall after being mounted, thereby playing the role of supporting, and preventing pedestrians from falling in the well to cause injuries and deaths. The safety protection screen of the underground well safety protection device has the advantages of high break-resistant strength, ageing resistance, corrosion resistance, safety, reliability and convenient mounting and the like, and can be used for 5-10 years underground.
Description
Technical field
The utility model relates to a kind of missile silo safety device, is particularly useful for the security protection of municipal well, electric power well, inspection shaft communication well, tap water well, manhole, combustion gas well, heating power well, sink hole, the missile silos such as well, lower well, catch-basin, lawn well, street lamp well that fall into water.
Background technology
Along with boisterous continuous generation, square or the circular manhole class facility such as city road inspection shaft, communication manhole, natural gas line, sewer, sewage conduct, feedwater piping is common again indispensable urban operating mechanism in the city, and the underground inspection well cover that is equipped with in a single day lose, stolen or rolled bad etc., the hazard event that will occur that the pedestrian falls into, wheel is blocked etc. and so on causes very big injury to pedestrian, vehicle.
In recent years owing to well lid lose, damage, because pedestrian's injures and deaths case that the reason such as well lid causes is removed in the draining water drainage to be occured repeatedly, civic life and property are caused very large loss, also become the hang-up of various places municipal sector.
Along with boisterous continuous generation, Rainfall Disaster has occured in China various places, so that the contingency that well lid is lost under the spot, its personal safety to normal trip has caused very large threat.
The utility model content
Technical problem to be solved in the utility model provides a kind of missile silo safety device simple and easy, that weight capacity is strong of installing.
The utility model adopts following technical scheme:
The utility model comprise be fixed in underground well lid below expansion hook hitch, described safety guard net outer side edges is along being provided with the link suitable with expansion hook hitch, and described expansion hook hitch is comprised of fastening screw, the spacing preiection and the fixed hook that are set in fastening bolt and the clamp nut on the fastening screw and are arranged at the fastening screw two ends.
The junction of the transverse and longitudinal connection cord of described safety guard net is provided with johning knot.
Described expansion hook hitch adopts stainless steel, stainless iron to make.
Good effect of the present utility model is as follows:
The utility model is fixedly installed on underground well lid below by expansion hook hitch with safety guard net, even if well lid is stolen or loss makes the people fall into well, can not cause casualties yet, the utility model is fixed in the borehole wall at 10-15cm place under the well head by the expansion hook hitch of the metal materials such as several stainless steels, stainless iron, protective screening can not become flexible after installation, come off, play a supporting role, prevent from that the pedestrian from falling into to cause injures and deaths.The missile silo protective screening has following characteristics: anti-fracture intensity is high, anti-aging, corrosion-resistant, safe and reliable, easy for installation etc., and 5-10 can be used in the down-hole.
Description of drawings
Accompanying drawing 1 is the utility model safety protective net structure schematic diagram.
Accompanying drawing 2 is the utility model expansion hook hitch structural representation.
The specific embodiment
Shown in accompanying drawing 1-2, the utility model comprises safety guard net 1, it is characterized in that the expansion hook hitch that it also comprises the metal materials such as stainless steel stainless iron that are fixed in underground well lid bottom, described safety guard net 1 outer side edges is along being provided with the link 2 suitable with expansion hook hitch, described expansion hook hitch is comprised of fastening screw, the spacing preiection 5 and the positioning hanger 6 that are set in fastening bolt 3 and the clamp nut 4 on the fastening screw and are arranged at the fastening screw two ends, and the junction of the transverse and longitudinal connection cord of described safety guard net 1 is provided with johning knot 7.
The utility model safety guard net by (some polypropylene fibre terylene, the braiding of rope that the strong materials of bearing capacity such as polyvinyl high strength yarn are made forms, between rope and the rope mutually knot become to detain.Each junction all has sling to fix, and to guarantee the evenly firm of mesh, the utility model safety guard net is the cobweb structure, outward appearance is the difformity such as square or circular, the expansion hook hitch that the utility model uses is the metal materials such as stainless steel stainless iron, and one is screw thread, and one has the vertebra degree.Outer bread one deck sleeve pipe, half has some otch the sleeve pipe cylinder, in their thiophene is accomplished fluently on the wall together holes, split nut then, nut pulls outward screw, and the vertebra degree is drawn in the cylinder sleeve pipe, and the cylinder sleeve pipe tightly is fixed on it on inwall of down-hole at last by spreading.
The utility model is equipped with for each underground inspection shaft and installs protective screening, in the situation that inspection well cover is lost, damaged under the spot, " eating the people " phenomenon of inspection shaft just can as much as possiblely be avoided, the anti-fracture intensity of the utility model is high, anti-aging, corrosion-resistant, safe and reliable, easy for installation etc., and 5-10 can be used in the down-hole.
