Abstract
A safety well lid is characterized in that a hole is punched in the center of the well lid, a countersunk head triangle knob switch is installed, a connection rod device is installed at the position, 200-300 mm below the well lid, at the bottom of the knob switch, the connection device at the bottom extends and retracts when the triangle knob switch at the center of the upper face of the well lid is rotated, connection rods at the two ends of the connection rod device extend out respectively to be plugged into holes installed in the well wall in advance when the triangle knob switch is turned on, the well lid is locked, a key is pulled out after the well lid is locked, people above the well lid can not pry or open the well lid, water flow can not float the well lid when an opening is filled with water, and safety of cars and pedestrians is ensured. When a person needs to descend a well for checking or maintenance, the key is plugged into the countersunk head triangle knob switch, the switch is rotated to the opened position, and then the well lid is opened.
Description
Technical field: Safety well cover belongs to urban construction field, is widely used in the irreplaceable product in civilian infrastructure field such as city or road, draining, communication, circuit, source of the gas, water source.
Background technology: by domestic and international complete search, Safety well cover is widely used in the municipal infrastructure in draining, communication engineering, water, electricity, the field such as warm, belong to irreplaceable product, consumption is very large, and existing well lid product cast iron with the easy breakage of cement or loss, the more important thing is at low speed place, city, due to ponding time rainy enter sewer time, be easy to that well lid is floated be subjected to displacement, and walk superincumbent pedestrian or vehicle blocks sight line due to ponding, do not see pavement behavior and have an accident.The object of the invention is to solve above-mentioned Problems existing, through Access point, in the industry, also not occurring innovation and creation and the product of identical type.
Summary of the invention: Safety well cover is characterized in that: the position punching being positioned at well lid center, countersunk head triangle turn-knob switch is installed, 200mm-300mm place installing connecting rods device below well lid is positioned at bottom turn-knob switch, above rotary well cover during the turn-knob delta switch of center, the linkage of bottom stretches out or retracts, when turn-knob delta switch is opened, the connecting rod at linkage two ends stretches out respectively, insert in the hole installed on the borehole wall in advance, realize the locking of well lid, after well lid locking, extract key out, people above just can not lever up or open well lid, same when opening collection full water, stream can not make well lid float, ensure the safety of vehicle and pedestrian, when needs go into the well inspection or maintenance, key is inserted countersunk head triangle turn-knob switch, twist switch is to the position of opening, get final product open manhole cover.
Safety well cover compared with prior art has the following advantages:
Structure is simple, and processing ease is safe and effective, anti-lost antitheft.
Accompanying drawing illustrates:
Accompanying drawing is Safety well cover schematic diagram.
1, Safety well cover 2, triangle turn-knob 3, well head
4, the borehole wall presets hole 5, connecting rod 16, linkage
7, connecting rod 28, private key
Detailed description of the invention: now illustrate to the drawings as examples: when Safety well cover (1) has been installed to (3) well head, insert on triangle turn-knob (2) switch by private key (8), rotate private key (8) to fastening position, pass on linkage (6) by the torsion transmitted, linkage (6) is rotated, drivening rod 1 (5) and connecting rod 2 (7), insert respectively in borehole wall preset hole hole (4), realize the locking of Safety well cover, then realized the unlatching of Safety well cover by opposite spin.
