[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1 A pole tower isolation device shown in the figure includes a fixing member 100 and a barrier assembly 200. The barrier assembly 200 is connected to the fixing member 100. The fixing member 100 is used to be fixed on a line pole or a line tower. The barrier assembly 200 is used to play the role of isolation and shielding, and plays a role of protection and warning for workers. The fixing member 100 and the barrier assembly 200 can be fixed to each other by welding, bolts, etc.

[0031] The barrier assembly 200 includes a plurality of blades 21 and a rotating shaft 23. The plurality of blades 21 are stacked and rotatably connected to the rotating shaft 23. The plurality of blades 21 can be stacked and overlapped to put the barrier assembly 200 in a folded state, and the plurality of blades 21 can be rotated by a predetermined angle along a set direction to put the barrier assembly 200 in an unfolded state. Through the design of overlapping the plurality of blades 21, when not in use, the plurality of blades 21 can be folded together, so that the outer dimensions of the barrier assembly 200 can be greatly reduced to facilitate the staff to take, and thus facilitate the staff to install the pole tower isolation device; when in use, the plurality of blades 21 only need to be unfolded, so that the barrier assembly 200 can form a sufficient barrier area (it should be noted that the barrier area refers to the area of ​​the barrier assembly 200 in the unfolded state) to protect the staff and other things.

[0032] The fan blades 21 can be made of lightweight insulating materials, which can play the role of insulation and isolation and can also greatly reduce the weight of the tower isolation device to facilitate the handling and operation of the staff.

[0033] The following will introduce the technical details of each component one by one.

[0034] In some embodiments, Figure 1 , Figure 2 As shown, in the direction from the end of the fan blade 21 close to the rotating shaft 23 to the end away from the rotating shaft 23, the width of the fan blade 21 gradually increases to form a fan-shaped structure. The fan-shaped structure can be very easily spliced ​​to form a semicircle, so that the fan blade 21 can relatively easily obtain a sufficient blocking area.

[0035] In addition to the above structure, adjacent blades 21 are coaxially arranged at one end close to the rotating shaft 23, and a plurality of blades 21 rotate in a predetermined direction at a predetermined angle to form a fan structure. The above design allows the blades 21 to be folded and unfolded very conveniently. When folded, a plurality of blades 21 overlap and stack, which can greatly reduce the external dimensions of the barrier assembly 200 for easy handling and installation; when unfolded, the blades 21 only need to be relatively rotated at a predetermined angle to form a larger fan structure to play a barrier role.

[0036] In some embodiments, the blades 21 are detachably connected to the rotating shaft 23. In actual use, the required barrier areas in different places may be different. Based on the above design, the barrier area of ​​the barrier assembly 200 can be changed by increasing or decreasing the number of blades 21. The detachable connection between the blades 21 and the rotating shaft 23 can easily increase or decrease the number of blades 21.

[0037] Specifically, one end of the fan blade 21 close to the rotating shaft 23 is provided with a through hole 04, and the fan blade 21 is sleeved on the rotating shaft 23 through the through hole 04; the rotating shaft 23 includes a shaft rod 231 and a tightening member 232, and the tightening member 232 is connected to the shaft rod 231.

[0038] In other embodiments, Figure 4 , Figure 5 As shown, the shaft 231 includes a rod 2311 and a supporting portion 2312. One end of the rod 2311 is provided with a thread, and the other end is connected to the supporting portion 2312. The fan 21 is sleeved on the rod 2311 and can be supported by the supporting portion 2312. The tightening member 232 is provided with a threaded hole. The tightening member 232 can be threadedly connected with the rod 2311 and tightly against the fan 21, thereby fastening the fan 21. The above connection method has a simple structure and can be very convenient for disassembling and installing the fan 21.

[0039] It can be understood that the above-mentioned tightening member 232 includes a screw-on portion 2321 and a screwing portion 2322, and the screw-on portion 2321 and the screwing portion 2322 are connected. The screw-on portion 2321 is used to be threadedly connected to the shaft 231, and the screwing portion 2322 is used for the operator to screw. The screwing portion 2322 can facilitate the operator to rotate the tightening member 232, and further facilitate the operator to install and disassemble the fan blade 21.

[0040] In other embodiments, Figure 4 As shown, the fan blade 21 has a first avoidance portion 05 at one end close to the rotating shaft 23. The first avoidance portion 05 is arranged on the side of the fan blade 21 close to the line pole, so that the fan blade 21 will not have structural conflict with the line pole during rotation, so that the fan blade 21 can rotate in close contact with the line pole.

[0041] In other embodiments, Figure 7 As shown, the side edge of the fan blade 21 is also provided with a second avoidance portion 06, which is recessed inward to form an arc-shaped recessed structure. Usually, the line pole tower is a cylindrical structure, and the arc-shaped recessed structure can better fit and contact the side of the line pole after the fan blade 21 is unfolded.

[0042] In some embodiments, Figure 1 , Figure 2 , Figure 3 As shown, a through hole 01 is provided at one end of the fan blade 21 away from the rotating shaft 23, and the through hole 01 is used to pass a rope. In actual use, after the fan blade 21 is unfolded, the relative positions between the fan blades 21 are not easy to be fixed. By passing a rope through the through hole 01, the fan blades 21 are connected together to fix the relative positions of the fan blades 21, thereby making the fan surface structure formed by the fan blades 21 more stable, so that the barrier can play a more stable barrier role.

[0043] In some embodiments, Figure 4 As shown, when the barrier assembly 200 is in the folded state, the through holes 01 of the plurality of blades 21 are aligned with each other. In practical applications, when the pole tower isolation device is not in use, the blades 21 may be unfolded, and the unfolded blades 21 are relatively weak. When stored, the unfolded blades 21 will increase the external dimensions of the pole tower isolation device and easily cause damage to the blades 21. In order to avoid the above-mentioned undesirable situation, when stored, the blades 21 can be bundled together through the through holes 01, thereby effectively preventing the blades 21 from spreading out when not in use.

[0044] In other embodiments, a locking structure is provided between two adjacent blades 21, and the locking structure can lock the two blades 21 after the two blades 21 rotate relative to each other at a preset angle, so that the two blades 21 can stably maintain a preset deployment angle. Figure 7 As shown, the fan piece 21 is provided with a fixing hole 07, and the barrier assembly 200 further includes a fixing member 24, which is used to pass through the fixing hole 07 to form the locking structure; when the barrier assembly 200 is in the unfolded state, the fixing holes 07 of two adjacent fan pieces 21 are coaxially aligned up and down, and the fixing member 24 passes through the fixing holes 07 of the two adjacent fan pieces 21 to engage and fix the two adjacent fan pieces 21, thereby enhancing the structural stability of the barrier assembly 200 after unfolding.

[0045] It is understandable that, since the barrier assembly 200 needs to have good insulation properties to provide good protection for the staff, the fixing member 24 is also made of insulating materials such as plastic, glass, and ceramic.

[0046] In other embodiments, the fan blade 21 is further provided with a magnetic attraction component, which includes a magnetic member and a magnetic conductive member (which may be an iron sheet), which are respectively embedded or bonded on the fan blade 21, and the magnetic member and the iron sheet are respectively close to the two sides of the fan blade 21. When the fan blade 21 is unfolded, the magnetic member and the iron sheet on two adjacent fan blades 21 are attracted to limit the relative rotation angle between the two adjacent fan blades 21, and when the fan blade 21 is folded, the magnetic members on the two adjacent fan blades 21 are attracted to each other to maintain the fan blade 21 in a folded state.

[0047] In some embodiments, Figure 2 , Figure 3 As shown, a limiting structure 22 is provided between two adjacent blades 21, and the limiting structure 22 is used to limit the rotation angle between two adjacent blades 21 to avoid excessive relative rotation of two adjacent blades 21, thereby making it impossible for the blades 21 to be fully unfolded to obtain sufficient blocking area. The limiting structure 22 can effectively limit the relative rotation angle between adjacent blades 21, so that each blade 21 can obtain sufficient blocking area after unfolding; and, in addition to the above effects, the limiting structure 22 can also enhance the connection between each blade 21, so that the fan surface structure formed by the blades 21 is more stable.

[0048] Specifically, Figure 2 , Figure 3 As shown, one of the two adjacent blades 21 is provided with a slide groove 02, and the other of the two adjacent blades 21 is provided with a protrusion 03, the protrusion 03 is at least partially provided in the slide groove 02 and can slide along the slide groove 02, and the slide groove 02 and the protrusion 03 form a limiting structure 22. The limiting structure 22 formed by the above structure is simple and easy to produce and process.

[0049] In some embodiments, Figure 2 As shown, in the vertical direction, the chute 02 is opened on the bottom surface of the fan blade 21, and the protrusion 03 is opened on the top surface of the fan blade 21. (It should be noted that the vertical direction refers to the direction in which the fan surface is perpendicular to the ground after installation) In actual use, the fan blade 21 is installed in an outdoor environment, and there are many falling objects in the outdoor environment. If the chute 02 is opened on the top surface of the fan surface, it will accumulate in the chute 02 and cause clogging of the chute 02 and affect the rotation of the fan blade 21. Therefore, opening the chute 02 on the bottom surface of the fan blade 21 can prevent the falling objects from accumulating inside the chute 02 and causing clogging of the chute 02.

[0050] In some embodiments, Figure 4 , Figure 6 As shown, the fixing member 100 includes a clamp 12 and a clamp 11, wherein the clamp 12 is used to connect the line tower, and the clamp 11 is used to connect the line pole, so that the pole tower isolation device can be conveniently fixed on the line pole and the line tower.

[0051] The clamp 11 includes a first portion 111 and a second portion 112. The first portion 111 and the second portion 112 are mirror images of each other. The first portion 111 and the second portion 112 are arranged opposite to each other and connected by bolts. In practical applications, the clamp 11 can be fixed on line poles of various sizes by adjusting the spacing between the first portion 111 and the second portion 112, thereby enhancing the adaptability of the pole tower isolation device.

[0052] The clamp 12 includes a first bending piece 121 and a second bending piece 122, which are arranged opposite to each other and connected by bolts, and both of the first bending piece 121 and the second bending piece 122 are L-shaped structures. In practical applications, a line tower is usually built with a steel frame with an L-shaped cross-section, and the first bending piece 121 and the second bending piece 122 are L-shaped structures that can be compatible with the L-shaped steel frame of the line tower, thereby facilitating the fixing of the pole tower isolation device to the line tower.

[0053] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
