Technical Field

[0001] The utility model relates to the technical field of construction safety protection devices, in particular to a high-voltage protection net device. Background Art

[0002] Due to the limitations of existing high-voltage power line facilities, future construction projects below the high-voltage power line will need to consider construction safety. Construction processes such as mechanical excavation, lifting, and self-unloading may all touch the high-voltage power line. In addition, there are visual blind spots or illusions at high altitudes. During high-altitude operations, humans cannot accurately judge or avoid touching the high-voltage power line, which can easily cause safety issues such as personal injury and equipment damage.

[0003] Therefore, in order to reduce the risk of triggering the high-voltage power line during construction and avoid the risk of secondary electric shock caused by damage and falling of the high-voltage power line, it is considered to install a protective net device in the construction area below the high-voltage power line; in view of this, we propose a high-voltage protective net device.

[0029] The following will be combined with 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7 The present invention describes the above technical solution in detail through the following embodiments:

[0031] A high-voltage protection net device includes a protection net body 1 for being arranged below a high-voltage line network facility, and further includes:

[0032] Two mounting parts, such as Figure 1 Installation diagram, the protective net body 1 is set between two installation parts, specifically, as Figure 2 and Figure 3 In the structure shown, each mounting portion includes two vertical trusses 2 and a truss unit 3 that moves along the two vertical trusses 2 through a power source. In this embodiment, a mounting base 5 is horizontally mounted on the vertical trusses 2, and an electric hoist 6 is installed between the mounting base 5 and the truss unit 3 as a power source. The truss unit 3 can be hoisted by the electric hoist 6 to adjust its vertical height. In this embodiment, a netting unit 4 is provided on the truss unit 3, and both ends of the protective net body 1 are respectively mounted on the two netting units 4, that is, Figure 1 The installation structure shown can pull up the protective net body 1 under the high-voltage network cable as a protective structure.

[0033] like Figure 4-Figure 6 As shown in the structure, the truss unit 3 in this embodiment includes two mouth-shaped frames 32 for being inserted into the two vertical trusses 2, and a horizontal truss 31 is installed between the two mouth-shaped frames 32. In order to facilitate the lifting and maintain the coverage area of the protective net body 1, a hanging frame 33 is installed on the mouth-shaped frame 32 on the side opposite to the horizontal truss 31. The hanging frame 33 is aligned with the mounting seat 5, as shown in FIG. Figure 1 、 Figure 2 Lateral mounting sites shown.

[0034] It should be noted that, in order to reduce the wear and resistance of the truss unit 3 during the movement along the vertical truss 2, the vertical truss 2 is surrounded by cylindrical steel frames, and the inner portion of the mouth frame 32 is provided with an insertion cavity 3201 for inserting the vertical truss 2. Figure 6 In the structure shown, a roller 321 for abutting against the vertical truss 2 is rotatably installed in the insertion cavity 3201. The roller 321 can achieve rolling friction, which facilitates the smooth lifting of the truss unit 3.

[0035] like Figure 4 and Figure 7 As shown in the structure, the netting unit 4 includes a connecting plate 43 with detachable mounting side blocks 42 on both sides, and the mounting side blocks 42 are detachably mounted with vertical rods 41 through the mounting holes 421 provided thereon. The vertical rods 41 are mounted on the horizontal truss 31. The netting unit 4 can install the protective net body 1 and at the same time make up for the height difference defect caused by the electric hoist 6 equipment, so that a higher protective net height can be obtained.

[0036] It should be noted that if Figure 7 As shown in the structure, a group of lugs 431 for mounting a mesh roller 44 are provided on the outer side of the connecting plate 43; specifically, in order to facilitate the winding and tensioning of the protective net body 1, a mesh roller 44 is rotatably mounted on the connecting plate 43 on one side through a motor 7, and a mesh roller 44 is fixedly mounted on the connecting plate 43 on the other side, and both ends of the protective net body 1 can be detachably mounted on the mesh rollers 44 on both sides; that is, when the device is implemented, they can be installed on two mesh rollers 44 respectively, but when the construction is completed, it is inconvenient to manually wind up, so the protective net body 1 on the side of the mesh roller 44 can be detachably fixed, and the other side motor 7 can be driven to quickly wind up; the mesh rollers 44 on both sides of other embodiments can also be fixedly mounted, and the protective net body 1 can be directly disassembled and wound up.

[0037] The working principle of the high-voltage protection net device of this embodiment is as follows: according to the construction requirements, the area below the high-voltage network line is as follows: Figure 1 As shown in the figure, two installation positions are planned, such as Figure 2 After installation, first install the two ends of the protective net body 1 on the net installation unit 4, and then hoist it to the truss unit 3 through the electric hoist 6 to complete the hoisting. Figure 3 and Figure 1 At the height shown, a protective net structure is formed under the high-voltage network cable, which is conducive to further improving the safety of construction below.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
