Description
Technical field
The utility model relates to a kind of falling proof device, is specifically related to a kind of cable shaft falling proof device.
Background technology
Along with socioeconomic development, urban development is advanced by leaps and bounds, and electric power is constantly for local economic development is contributed.The development of electric utility, city cable changes into as another bright spot in urbanization process, and cable is with himself own advantage, when improving constantly power supply reliability, for the city look and feel in city have increased brilliance.Along with improving constantly of cable rate, cable shaft is also more and more, and cable well lid becomes the inevitable outcome of development, but the loss of cable well lid, breakage but become potential safety hazard.Therefore for further carrying out management innovation, requirement has urgently been proposed, must adopt an effective measure, at cable shaft, anti-drop net measure is installed, avoids the generation due to accidents such as manhole cover loss, breakage cause casualties, guarantee the safe and reliable operation of power equipment simultaneously.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of cable shaft falling proof device is provided, and simple in structure, reasonable in design, safe.
The utility model solves the technical scheme that its technical problem adopts:
Cable shaft falling proof device described in the utility model, comprise anti-drop net and expansion hook, the edge of anti-drop net is fixed on annular retractable circle, annular retractable circle hangs on expansion hook, expansion hook is fixed on the borehole wall, and the top of expansion hook is provided with garland, and garland is fixed on the borehole wall, the edge of waterproof film is fixed on garland, on annular retractable circle, is provided with small bell.
Described expansion hook is that equalization is arranged on the borehole wall.
Described small bell is that equalization is arranged on annular retractable circle.
Operating principle and process:
Anti-drop net is fixed on and on the borehole wall, can prevents that pedestrian's well that falls is injured, and annular retractable circle makes anti-drop net be applicable to the cable shaft of all size, if pedestrian falls into anti-drop net accidentally, pedestrian can rock small bell and seek help; If rain infiltrates, rainwater can fall into and on waterproof film, flow into garland again and discharge, and avoids rainwater to drop on anti-drop net and annular retractable circle and causes corrosion, brings potential safety hazard.
The beneficial effect that the utility model has is: reasonable in design, simple in structure, safe, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model top view;
In figure: 1, anti-drop net; 2, expansion hook; 3, annular retractable circle; 4, garland; 5, waterproof film; 6, small bell; 7, the borehole wall.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, the utility model comprises anti-drop net 1 and expansion hook 2, the edge of anti-drop net 1 is fixed on annular retractable circle 3, annular retractable circle 3 hangs on expansion hook 2, expansion hook 2 is fixed on the borehole wall 7, and the top of expansion hook 2 is provided with garland 4, and garland 4 is fixed on the borehole wall 7, the edge of waterproof film 5 is fixed on garland 4, is provided with small bell 6 on annular retractable circle 3.
Expansion hook 2 is that equalization is arranged on the borehole wall 7.
Small bell 6 is that equalization is arranged on annular retractable circle 3.
Anti-drop net 1 is fixed on and on the borehole wall 7, can prevents that pedestrian's well that falls is injured, and annular retractable circle 3 makes anti-drop net 1 be applicable to the cable shaft of all size, if pedestrian falls into anti-drop net 1 accidentally, pedestrian can rock small bell 6 and seek help; If rain infiltrates, rainwater can fall on waterproof film 5 and flow into garland 4 discharges again, avoids rainwater to drop on anti-drop net 1 and annular retractable circle 3 and causes corrosion, brings potential safety hazard.
