[0006] Therefore, the object of the present invention is to provide an electrically-charged anisotropic umbrella-shaped shielding cover for a tension pole of a distribution line.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a live anisotropic umbrella-shaped shielding cover for a tension pole of a distribution line comprises a telescopic assembly, comprising a fixed pole and a sliding pole arranged inside the fixed pole, wherein the sliding pole and the fixed pole are connected to an insulating soft pole through a hinge; and

[0008] The insulating assembly includes an insulating blanket arranged on the side wall of the insulating soft rod, which is used to wrap and insulate the wrapping point. The insulating blanket is symmetrically arranged with respect to the central axis of the fixed rod, and the two insulating blankets are connected by a locking piece.

[0009] As a preferred solution of the live anisotropic umbrella-shaped shielding cover for the distribution line tension pole of the present invention, the telescopic assembly also includes a spring buckle arranged on the inner wall of the sliding rod, pressing the spring buckle can drive the wedge block to move inward to cancel the lock on the fixed rod, and the side wall of the sliding rod is provided with an anti-slip insulating rubber sleeve to reduce the sliding phenomenon during movement.

[0010] As a preferred solution of the live anisotropic umbrella-shaped shielding cover for the distribution line tension pole of the present invention, the hinged part includes a connecting rod arranged at the top end of the fixed rod, and the interior of the connecting rod is hinged to the diagonal support rod through a ring rod.

[0011] As a preferred solution of the live anisotropic umbrella-shaped shielding cover for the distribution line tension pole of the present invention, the hinged part also includes a limit groove arranged at the top end of the sliding rod for limiting the moving range of the sliding rod, one end of the insulating soft rod is hinged to the sliding rod, and the insulating soft rod and the diagonal support rod are symmetrically arranged with respect to the central axis of the sliding rod.

[0012] As a preferred solution of the live anisotropic umbrella-shaped shielding cover for the distribution line tension pole of the present invention, the insulating soft rod is located on the side wall of the insulating blanket to facilitate deformation according to the object and reduce the obstruction of the object to the insulating blanket.

[0013] As a preferred solution of the live anisotropic umbrella-shaped shielding cover for the distribution line tension pole of the present invention, the insulating assembly also includes an insulating hard rod arranged at one end of the insulating soft rod away from the sliding rod, and the side wall of the insulating hard rod is connected to the locking piece.

[0014] As a preferred solution of the live anisotropic umbrella-shaped shielding cover for the distribution line tension pole of the present invention, the end of the insulating hard rod is connected to the insulating blanket, and the insulating blanket is arranged in a "trapezoidal" shape, and the insulating blanket is wrapped around by the insulating hard rod and the insulating soft rod to improve the stability of the movement of the insulating blanket.

[0015] As a preferred solution of the live anisotropic umbrella-shaped shielding cover for the distribution line tension pole of the present invention, the locking member includes a fixed block arranged on one of the side walls of the insulating hard pole, and the top of the fixed block is provided with a first inclined surface and a second inclined surface, and the bottom ends of the first inclined surface and the second inclined surface are located in adjacent positions.

[0018] Beneficial effects of the present invention: The present invention can quickly complete the insulation wrapping of the live area in a short time through the linkage design of the sliding rod and the insulating soft rod.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1, reference Figure 1 to Figure 3 and Figure 5 , which is the first embodiment of the present invention, provides a live heterogeneous umbrella-shaped shielding cover for a distribution line tension pole, including a telescopic component 100 that can drive an insulating component 200 to move, thereby effectively insulating the live area and ensuring the safety of operators.

[0035] Specifically, the telescopic assembly 100 includes a fixed rod 101, a sliding rod 102 disposed inside the fixed rod 101, and the sliding rod 102 and the fixed rod 101 are connected to the insulating soft rod 104 through a hinge 103. The sliding rod 102 moves along its axis inside the fixed rod 101, and the insulating soft rod 104 moves accordingly through the transmission of the hinge 103. The insulating soft rod 104 has a certain elasticity and can be deformed when encountering an irregular object, so as to better fit the charged area, thereby improving the insulation effect, wherein the sliding rod 102 and the fixed rod 101 are both made of insulating materials.

[0036] Furthermore, the telescopic assembly 100 also includes a spring buckle 105 arranged on the inner wall of the sliding rod 102. Pressing the spring buckle 105 can drive the wedge block 106 to move inward to cancel the lock on the fixed rod 101, and the side wall of the sliding rod 102 is provided with an anti-slip insulating rubber sleeve 107 to reduce the slipping phenomenon during movement.

[0037] Furthermore, the hinged member 103 includes a connecting rod 103a disposed at the top end of the fixing rod 101, and the interior of the connecting rod 103a is hinged to the diagonal support rod 103c via a ring rod 103b.

[0038] Furthermore, the hinge 103 also includes a limit groove 103d arranged at the top of the sliding rod 102 for limiting the movement range of the sliding rod 102. One end of the insulating soft rod 104 is hinged to the sliding rod 102, and the insulating soft rod 104 and the diagonal support rod 103c are symmetrically arranged with respect to the central axis of the sliding rod 102.

[0039] Furthermore, the insulating soft rod 104 is located on the side wall of the insulating blanket 201 so as to be deformed according to the object and reduce the obstruction of the object to the insulating blanket 201 .

[0040] Operation process: Move the charged anisotropic umbrella-shaped shielding cover of the distribution line tension pole to just below the operation point to ensure that the device is in the correct working position. The operator stands in a safe position and pushes the sliding rod 102 downward. The sliding rod 102 moves along its axial direction inside the fixed rod 101. As the sliding rod 102 moves downward, the hinge 103 (including the connecting rod 103a, the ring rod 103b and the diagonal support rod 103c) drives the insulating soft rod 104 to move inside the fixed rod 101. Since the insulating soft rod 104 has a certain elasticity, it can deform according to the shape of the charged object and fit the charged area more closely. The movement of the insulating soft rod 104 will drive the insulating blankets 201 on both sides to gradually close. During the closing process of the insulating blanket 201, the plug rods 203c at both ends are concentrated towards the middle slot 203b through the inclination of the first inclined surface M-1 and the second inclined surface M-2. When the insulating blanket 201 is completely closed, the plug rod 203c is inserted into the slot 203b. Through the action of the downward tightening force, the plug rod 203c is firmly fixed in the slot 203b, ensuring the sealing of the insulating blanket 201. When the sliding rod 102 is pulled down, the wedge block 106 on the side wall of the fixed rod 101 will automatically insert into the limiting hole of the sliding rod 102 to limit the sliding rod 102 and prevent it from moving accidentally. When it is necessary to release the fixing of the insulating blanket 201, press the spring buckle 105 to drive the wedge block 106 to move inward, so that it is out of the limiting hole and the locking of the sliding rod 102 is cancelled. Pull the pull ring 203e, and pull the plug rod 203c out of the slot 203b through the pull ring 203e to cancel the fixing of the insulating blanket 201. The plug rod 203c returns to its original position under the elastic force of the telescopic spring 203d, which is convenient for the next use.

[0041] Example 2, reference Figure 1 and Figure 4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that an insulating hard rod 204 is added to the design of the insulating blanket 201, thereby improving the stability and reliability of the insulating blanket 201 during movement, and further enhancing the practicability and safety of the device.

[0042] Specifically, the insulating assembly 200 includes an insulating blanket 201 arranged on the side wall of the insulating soft rod 104, which is used to wrap and insulate the wrapping point. The insulating blanket 201 is symmetrically arranged with respect to the central axis of the fixed rod 101, and the two insulating blankets 201 are connected by a locking member 203.

[0043] Furthermore, the insulating assembly 200 also includes an insulating hard rod 204 disposed at one end of the insulating soft rod 104 away from the sliding rod 102 , and a side wall of the insulating hard rod 204 is connected to the locking member 203 .

[0044] Furthermore, the end of the insulating hard rod 204 is connected to the insulating blanket 201, and the insulating blanket 201 is arranged in a "trapezoidal" shape, and the insulating blanket 201 is wrapped around by the insulating hard rod 204 and the insulating soft rod 104 to improve the stability of the movement of the insulating blanket 201.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Operation process: Move the charged anisotropic umbrella-shaped shielding cover of the distribution line tension pole to the bottom of the operation point to ensure that the device is in the correct working position. The operator stands in a safe position and pushes the sliding rod 102 downward. The sliding rod 102 moves along its axial direction inside the fixed rod 101. As the sliding rod 102 moves downward, the hinge 103 (including the connecting rod 103a, the ring rod 103b and the diagonal support rod 103c) drives the insulating soft rod 104 to move inside the fixed rod 101. Since the insulating soft rod 104 has a certain elasticity, it can deform according to the shape of the charged object and fit the charged area better. The movement of the insulating soft rod 104 will drive the insulating blankets 201 on both sides to gradually close. During the closing process of the insulating blanket 201, the locking parts 203 at both ends are concentrated to the middle through the action of the inclined surface. The insulating hard rod 204 is located at the end of the insulating soft rod 104 away from the sliding rod 102 and is connected to the end of the insulating blanket 201. The rigid design of the insulating hard rod 204 helps to improve the stability of the insulating blanket 201 during movement, ensuring that the insulating blanket 201 can be closed and locked smoothly. When the insulating blanket 201 is completely closed and covers the live area, the two insulating blankets 201 are connected together by the locking member 203 to ensure the sealing of the insulating blanket 201. The design of the locking member 203 enables the insulating blanket 201 to be firmly fixed around the live area to form a complete insulating barrier. During the downward pull of the sliding rod 102, the wedge block 106 on the side wall of the fixed rod 101 will automatically insert into the limiting hole of the sliding rod 102 to limit the sliding rod 102 and prevent it from moving accidentally. When it is necessary to release the fixing of the insulating blanket 201, press the spring buckle 105 to drive the wedge block 106 to move inward, so that it is out of the limiting hole and the locking of the sliding rod 102 is cancelled. Pull the unlocking device on the locking member 203 to loosen the locking member 203 and release the connection between the two insulating blankets 201.

[0047] Example 3, reference Figure 4 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that the locking member 203 can not only ensure the tight fit and fixation of the insulating blanket 201 when it is closed, but also can be easily unlocked and reset, which greatly improves the safety and efficiency of live working.

[0048] Specifically, the locking member 203 includes a fixed block 203a arranged on the side wall of one of the insulating hard rods 204, and the top of the fixed block 203a is provided with a first inclined surface M-1 and a second inclined surface M-2, and the bottom ends of the first inclined surface M-1 and the second inclined surface M-2 are located in adjacent positions.

[0049] Furthermore, the locking member 203 also includes a slot 203b disposed between the first inclined surface M-1 and the second inclined surface M-2. The slot 203b is located on the side wall of the fixed block 203a. The fixed block 203a is disposed on the side wall of an insulating hard rod 204, and the top of the fixed block 203a is designed with the first inclined surface M-1 and the second inclined surface M-2. The bottom ends of the two inclined surfaces are located in adjacent positions to form a guiding structure so that the insertion rod 203c can slide smoothly into the slot 203b. The slot 203b is located on the side wall of the fixed block 203a, between the first inclined surface M-1 and the second inclined surface M-2. The slot 203b is designed to receive and fix the insertion rod 203c to ensure that the insulating blanket 201 remains stable in the closed state.

[0050] Furthermore, the locking member 203 also includes an insertion rod 203c arranged on another insulating hard rod 204, and a telescopic spring 203d is arranged between the insertion rod 203c and the insulating hard rod 204. A pull ring 203e is installed at one end of the insertion rod 203c. After the insertion rod 203c is fully inserted into the slot 203b, the telescopic spring 203d continues to provide inward pressure to ensure that the insertion rod 203c will not fall off easily, thereby maintaining the sealing and stability of the insulating blanket 201.

[0051] The rest of the structure is the same as that of Example 2.

[0052] Operation process: This device is inverted in an umbrella shape. The operator moves to the bottom of the insulation wrapping operation point and pushes the sliding rod 102 downward. The sliding rod 102 drives the insulating soft rod 104 to move into the fixed rod 101. The insulating soft rod 104 is made of a material with a certain elasticity. When it encounters an irregular object, it can deform to fit the charged area more closely, thereby driving the insulating blankets 201 on both sides to close together to achieve insulation of the charged area. The diagonal support rod 103c is used to improve the stability of the insulating blanket 201 during movement. When the insulating blanket 201 is closed, the insertion rod 203c passes through the first inclined The inclination of the inclined surface M-1 and the second inclined surface M-2 causes the insertion rod 203c to concentrate on the middle slot 203b, and the pulling-down tightening force can effectively make the insertion rod 203c inserted into the interior of the slot 203b to fix the insulating blanket 201, wherein the insertion rod 203c and the slot 203b are located at both ends of the insulating blanket 201, which can effectively improve the sealing of the insulating blanket 201, and wherein the sliding rod 102 can effectively make the wedge block 106 on the side wall of the fixed rod 101 inserted into the limiting hole of the sliding rod 102 to limit the sliding rod 102 during the pulling-down process.

[0053] When there is no need to limit the sliding rod 102, pressing the spring buckle 105 drives the wedge block 106 to move inward, so that the wedge block 106 is separated from the limiting hole, making it more convenient to cancel the fixing of the sliding rod 102.

[0054] When it is necessary to cancel the insulation of the live part of the insulating blanket 201, pull the pull ring 203e, and the pull ring 203e can be used to pull the plug rod 203c out of the slot 203b to cancel the fixation of the insulating blanket 201. After the fixation of the plug rod 203c is canceled, the elastic force of the telescopic spring 203d can effectively drive the plug rod 203c to return to its original position to facilitate the next insertion of the plug rod 203c into the slot 203b. The plug rod 203c is arranged in a cross shape, and the horizontal block on the plug rod 203c is to facilitate the insertion of the plug rod 203c into the slot 203b and reduce the retraction of the plug rod 203c.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
