DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1

[0030] This embodiment provides an adjustable protective device for power engineering construction, such as Figure 1 As shown, it includes several protective units 1 connected in sequence, each protective unit 1 includes two columns 11 and several protective rods 12, a support seat 13 is provided at the lower end of the two columns 11, a connecting plate 14 and a connecting rod 15 are connected in parallel between the two columns 11, the connecting plate 14 is connected to the lower part of the column 11, and the connecting rod 15 is connected to the upper part of the column 11, and several protective rods 12 are evenly arranged, and the lower ends are fixed on the connecting plate 14, and the upper parts are fixed on the connecting rod 15; the side surfaces of the two columns 11 that are away from each other are respectively provided with an inner frame 16 and an outer frame 17, and the columns 11 of the two adjacent protective units 1 that are close to each other are respectively provided with an inner frame 16 and an outer frame 17, and the inner frame 16 is detachably sleeved in the outer frame 17.

[0031] This embodiment includes multiple protection units 1, which are detachably connected via an inner frame 16 and an outer frame 17. This allows the units 1 to be disassembled and stacked together when not in use, saving space. For larger construction sites and larger protective devices, the units can be disassembled and moved flexibly when changing protective positions. The lower placement of the support base 13 and connecting plate 14 in this embodiment lowers the center of gravity of the device, increasing its overall stability.

[0032] Example 2

[0033] The inner sleeve 16 of this embodiment is detachably sleeved in the outer sleeve 17 in the following manner: the inner sleeve 16 is sleeved in the outer sleeve 17, and threaded holes are provided on the top and bottom of the inner sleeve 16 and the outer sleeve 17, respectively. Figure 3 As shown, the bottom and top of the inner frame 16 and the outer frame 17 are fixed by screwing bolts 2 into corresponding threaded holes.

[0034] The rest is the same as in Example 1.

[0035] Example 3

[0036] The inner sleeve frame 16 of this embodiment is detachably sleeved in the outer sleeve frame 17 in the following manner: the inner top and the inner bottom of the outer sleeve frame 17 are both provided with spring grooves 3 facing outwards, and springs 4 are provided in the spring grooves 3. Figure 4 As shown, the ends of the two springs 4 close to each other are provided with clips 5, and the ends of the two clips 5 close to each other are arc-shaped. The top and bottom of the inner sleeve frame 16 are respectively provided with slots 6 corresponding to the two clips. The shape of the slots 6 is adapted to the ends of the clips 5, and the clips 5 are clamped in the slots 6.

[0037] In this embodiment, the end surface of the inner sleeve frame 16 close to the outer sleeve frame 17 is a curved surface, and the connecting portion between the slot 6 and the outer surface of the inner sleeve frame 16 is also a curved surface.

[0038] The rest is the same as in Example 1.

[0039] When using this embodiment, the inner sleeve 16 is moved together with the protective unit 1 in which it is located toward the corresponding outer sleeve 17 until it enters the outer sleeve 17. After entering the outer sleeve 17, the outer surface of the inner sleeve 16 presses the clamping member 5 to move (the clamping member presses the spring) until the clamping member 5 is snapped into the slot 6. The curved surface makes it easier for the inner sleeve 16 to enter the outer sleeve 17 and makes it easier for the clamping member 5 to be snapped into the slot 6 for connection. When disassembly is required, the inner sleeve 16 is moved outward, and force is applied to disengage the clamping member from the slot 6. The inner sleeve 16 presses the clamping member 5 outward until it is free from the outer sleeve 17, completing the disassembly.

[0040] Example 4

[0041] The inner sleeve frame 16 of this embodiment is detachably sleeved in the outer sleeve frame 17 in the following manner: the outer sleeve frame 17 is hollow and has an upper opening 7 adapted to the inner sleeve frame 16 at the top, and a side opening 8 close to the side of the inner sleeve frame 16. Figure 5 and 6 As shown, ( Figure 5 and 6(The figure shows a structure with a connecting rope) The side opening 8 is narrower than the upper opening 7, and limiting grooves 9 are provided on the two side surfaces of the inner frame 16 corresponding to the two side parts of the outer frame 17 forming the side opening 8. In this embodiment, the two parts of the outer frame 17 forming the side opening are called clamping parts 22, and the clamping parts 22 are placed in the limiting grooves 9; the two side surfaces of the upper opening 7 are respectively hinged with limiting plates 10, and the two limiting plates 10 are respectively connected to the two inner side surfaces of the outer frame 17 through elastic columns 20; the top of the outer frame 17 is located on both sides of the upper opening 7 and is also provided with rotation limiting devices 21, which can be rotatably placed above the limiting plates 10.

[0042] Preferably, the side surfaces of the two limiting plates 10 that are close to each other are arc surfaces.

[0043] The rest is the same as in Example 1.

[0044] When using this embodiment, the end of the protective unit 1 provided with the inner sleeve frame 16 is lifted, so that the inner sleeve frame 16 is snapped into the outer sleeve frame 17 from top to bottom through the upper opening 7 (the snap portion 22 corresponds to the limit slot 9 and is downward). The snapping process squeezes the limit plate 7 downward (squeezes the elastic column 20 downward. When the elastic column is not under force, it can support the limit plate 10 to be set horizontally). After the snapping, the snap portion 22 is placed in the limit slot 9, horizontally limiting the inner sleeve frame 16 and preventing it from moving out. The limit plate 10 is reset to a horizontal position by the elastic force of the elastic column 20. The rotation limit device 21 can be rotated above the limit plate 10 to limit it, preventing the inner sleeve frame 16 from being forced upward to squeeze the limit plate 10 during use and sliding out of the outer sleeve 17, thereby disconnecting. When disassembly is required, the rotation limit device 21 is rotated to a state where it is not on the limit plate 10, and the inner sleeve frame 16 is moved upward out of the outer sleeve 17.

[0045] Example 5

[0046] The rotation limiting device 21 of this embodiment includes a support column 211, a limiting plate 212 and a rotating plate 213. The support column 211 is fixed to the top of the outer frame 17, the limiting plate 212 is arranged on the top of the support column 211, and the rotating plate 213 is rotatably arranged on the support column 211. Figure 7-10 shown.

[0047] The rest is the same as Example 4.

[0048] In this embodiment, the rotating plate 213 can be rotated to the top of the limiting plate 10 or not according to whether or not the limiting plate 10 needs to be limited.

[0049] Example 6

[0050] In this embodiment, the connecting rod 15, the inner frame 16 and the outer frame 17 are all hollow, and the two upright posts 11 of each protection unit 1 are provided with connecting holes 18 corresponding to the connecting rod 15. Figure 2As shown, the connecting rod 15 , the connecting through hole 18 , the inner casing 16 and the outer casing 17 are interconnected and connected by a connecting rope 19 .

[0051] The rest is the same as in Example 1.

[0052] The setting of the connecting rope 19 in this embodiment can flexibly connect the various protective units 1 after the protective device is disassembled into the various protective units 1 to form a whole, which makes it more convenient to move the various disassembled protective units 1 as a whole. The connecting rope 19 does not need to be set to a straight state inside the protective device. A part of the length of the connecting rope 19 needs to be reserved for the connection between the various protective units 1, and for folding, stacking or moving the disassembled protective units 1.

[0053] Example 7

[0054] The connecting rope 19 of this embodiment is an elastic rope.

[0055] The rest is the same as Example 6.

[0056] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary engineering technicians in this field should fall within the scope of protection of the present invention.
