DETAILED DESCRIPTION

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] See also Figure 1-Figure 5 As shown, an electric power construction protection device includes a mounting plate 1, the mounting plate 1 is composed of two semicircular blocks 11, each semicircular block 11 is slidably provided with a plurality of protection mechanisms 2 for expanding above the mounting plate 1, the protection mechanism 2 includes a shielding plate 21 and a connecting rod driving mechanism 3 for driving the shielding plate 21 to expand and contract, the connecting rod driving mechanism 3 includes a hinged rod 31 and a positioning mechanism 4 for locking the hinged rod 31, the electric power construction protection device also includes a connecting mechanism 5 arranged on the semicircular block 11 for connecting the two semicircular blocks 11, and a clamping mechanism 6 for fixing the semicircular block 11 on the wire rod, and a circular hole for the power wire rod to pass is reserved between the two semicircular blocks 11.

[0031] When carrying out power construction, firstly, the two semicircular blocks 11 are assembled according to the diameter of the pole through the connecting mechanism 5. After assembly, the shielding plate 21 is slid and expanded in the horizontal straight line direction through the connecting rod driving mechanism 3. The shielding plate 21 can be expanded above the construction site by sliding and expanding, so that the user can continue to adjust the expansion angle of the shielding plate 21 according to the actual situation on site, which is convenient for adapting to different construction environments and improves the flexibility of the device.

[0032] See also Figure 5-Figure 8 As shown, the connecting rod driving mechanism 3 also includes a sliding block 32, a travel groove 33, a second extension plate 34, a sliding groove 35 and a limiting rod 36; the sliding block 32 is slidably set on the travel groove 33 along the expansion direction of the shielding plate 21, and the sliding block 32 is fixed to the end of the shielding plate 21; the travel groove 33 is opened on the mounting plate 1 and has a plurality of, and the shielding plate 21 is slidably matched with the travel groove 33; the second extension plate 34 is slidably set below the shielding plate 21; the sliding groove 35 is opened on the second extension plate 34; the limiting rod 36 is set on the shielding plate 21 and slidably matches with the notch of the sliding groove 35.

[0033] When the shielding plate 21 is expanding, the shielding plate 21 can slide along the travel groove 33 through the sliding block 32, and the expansion movement can be carried out during the sliding of the shielding plate 21. In this process, since the second extension plate 34 can slide with the limiting rod 36 set on the shielding plate 21 through the sliding groove 35, when the shielding plate 21 is expanding, the second extension plate 34 can be driven to slide along the limiting rod 36 through the sliding groove 35 to follow the expansion of the shielding plate 21. After the shielding plate 21 is expanded, the second extension plate 34 can be expanded synchronously, so that the shielding range can be adjusted by the expansion of the shielding plate 21 during construction, which is convenient for adapting to different construction environments and improves the flexibility of the device.

[0034] See also Figure 6-Figure 8 As shown, the connecting rod driving mechanism 3 also includes a travel block 37, a positioning rod 38 and a second connecting rod 39; the travel block 37 is slidably arranged on the mounting plate 1 in a horizontal straight line direction; the positioning rod 38 is arranged on the travel block 37 and has a pair; the second connecting rod 39 is arranged on the travel block 37 and is rotatably connected to the pulling end of the hinged rod 31.

[0035] When it is necessary to adjust the expansion angle of the shielding plate 21, first pull the travel block 37, and then drive the sliding block 32 to slide along the positioning rod 38 in the horizontal straight line direction. During the sliding process of the travel block 37, the second connecting rod 39 rotatably connected to it can be driven to pull and tilt. When the second connecting rod 39 is pulled, the hinged rod 31 rotatably connected to it can be driven to rotate and swing close to the shielding plate 21. When the hinged rod 31 contacts the shielding plate 21, the shielding plate 21 can be driven to slide along the travel groove 33 through the sliding block 32, so as to realize the expansion movement of the shielding plate 21. The expansion movement of the shielding plate 21 is realized by the horizontal straight line sliding of the hinged rod 31 and the second connecting rod 39 by the travel block 37.

[0036] See also Figure 5-Figure 7 As shown, the positioning mechanism 4 includes a linear limiting groove 41, a guide rod 42 and a locking rod 43; the linear limiting groove 41 is opened on the mounting plate 1 and is used to limit the horizontal linear sliding of the travel block 37; the guide rod 42 is arranged on the linear limiting groove 41 and is clearance-matched with the travel block 37; the locking rod 43 is bolted on the travel block 37 and is tightly pressed against the guide rod 42, and a return spring 421 is arranged on the guide rod 42 to drive the sliding block 32 to slide in the horizontal linear direction, and the two ends of the return spring 421 are respectively fixed to the linear limiting groove 41 and the end of the sliding block 32.

[0037] When it is necessary to fix the angle of the expanded baffle plate 21, in the initial state, the locking rod 43 and the guide rod 42 are in a tight state. In this state, the position of the travel block 37 is fixed, and the return spring 421 is in a compressed state, and will not drive the baffle plate 21 to expand. At this time, the baffle plate 21 is in a locked state. When it is necessary to expand the baffle plate 21, it is only necessary to rotate the locking rod 43 in the opposite direction until the locking rod 43 loses the tight effect on the guide rod 42. At this time, the travel block 37 that has lost its fixing force and the compressed return spring 421 are released, thereby pushing the travel block 37 to slide horizontally and linearly. During the sliding process, the baffle plate 21 can be expanded by the second connecting rod 39 and the hinged rod 31, so as to fix the expansion angle of the baffle plate 21 and to store and fix the baffle plate 21, thereby preventing the baffle plate 21 from expanding freely.

[0038] See also Figure 1 and Figure 2 As shown, the connecting mechanism 5 includes a positioning block 51, a threaded rod 52 and a locking nut 53; the positioning block 51 is arranged on the mounting plate 1 and has a plurality of them; the threaded rod 52 is threadedly connected to the positioning block 51 and has a pair; the locking nut 53 is threadedly connected to the threaded rod 52.

[0039] When a pair of semicircular blocks 11 need to be quickly installed and docked, first make the pair of semicircular blocks 11 on the same horizontal plane, then thread the threaded rod 52 to the pair of positioning blocks 51, and finally thread the locking nut 53 to the threaded rod 52 to dock the pair of semicircular blocks 11, thereby realizing quick installation and disassembly of the mounting plate 1.

[0040] See also Figure 2-Figure 6 As shown, the clamping mechanism 6 includes a screw rod 61, a round rod 62 and a clamping block 63; the screw rod 61 is rotatably set on the mounting plate 1 and is located below the travel block 37; the round rod 62 is set below the mounting plate 1 and has a plurality of them; the clamping block 63 is threadedly mounted on the screw rod 61, and the clamping block 63 and the round rod 62 are clearance-matched. The clamping block 63 is preferably a semicircular shape that better fits the outer wall of the wire rod. An anti-sliding block can be set at one end of the clamping block 63 that faces the wire rod to increase the friction between the clamping block 63 and the wire rod and improve the clamping effect of the clamping block 63.

[0041] When the mounting plate 1 needs to be fixed on the wire rod, the threaded clamping block 63 can be slid in the horizontal straight line direction along the circular rod 62 by rotating the screw rod 61 until the clamping block 63 is in contact with the wire rod and fixed, thereby fixing the wire rod. Wire rods of different diameters can be adjusted and fixed.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
