Abstract
The invention discloses a sand wind snow barrier device capable of being opened and closed and belongs to anti-wind equipment. The sand wind snow barrier device capable of being opened and closed is composed of a wind resisting plate, a support frame, a connecting rod, a connecting rotary shaft, a hinge and an open-and-close pull rod. The wind resisting plate is installed on the connecting rod. The connecting rod is connected with the support frame through the connecting rotator shaft. One end of the connecting rod is connected with the open-and-close pull rod through the hinge. Closing or opening of the sand wind snow barrier device can be achieved by pushing the open-and-close pull rod to displace vertically. Compared with the prior art, the sand wind snow barrier device capable of being opened and closed has the advantages of being capable of being freely opened and closed, economical and practical, simple and fast to operate, and convenient to use.
Description
Technical field
The invention belongs to the protection from the wind in windproof field, be specifically related to a kind of dust storm snowbreak device that can open and close of administering for wind, sand, snow injury.
Background technology
Strong wind sand and wind snow not only can seriously block the traffic, and can cause soil erosion and desertification of land simultaneously.
Existing dust storm snowbreak is all plane baffle plates of fixing, the angle that can not regulate choke plate.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple in structure, economical and practical dust storm snowbreak that can open and close, and reduces the disaster impact.
For achieving the above object, the present invention adopts following solution, and it is comprised of choke plate, bracing frame, connecting rod, connection rotating shaft, hinge, switching pull bar; Choke plate is arranged on connecting rod, and connecting rod is connected with bracing frame by connection rotating shaft, an end of connecting rod by hinge be connected pull bar and connect, open and close the pull bar upper and lower displacement by promotion and can realize closing or opening.
Effective choke area of described choke plate is 20%-80% of the choke plate area of plane.
Principle of the present invention is: when dust storm snow during by this device, because the choke effect of choke plate reduces its kinetic energy and takes husky snow ability, thereby reach the purpose of improvement.Pull downwards simultaneously when opening and closing pull bar, choke plate can be realized opening.When upwards promoting to open and close pull bar, choke plate can be realized closing.
Compared with prior art, the present invention has following advantage:
1, the present invention can free opening and closing, and is economical and practical.
2, the present invention is simple to operation, and is easy to use.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure: 1., bracing frame, 2., choke plate, 3., connecting rod, 4., hinge, 5., open and close pull bar, 6., connection rotating shaft.
The specific embodiment
Embodiment: shown in Figure 1,1. the present embodiment comprises two bracing frames, and 3. 6. 1. bracing frame connect some connecting rods by connection rotating shaft; 2. 3. connecting rod be installed with choke plate, and a connecting rod end 3. is 4. 5. hinged with the switching pull bar by hinge.
4. described hinge is bolted by hinge plate and forms
Described choke plate effective choke area 2. is 20%-80% of the choke plate area of plane.
