[0002] The falling of distribution and transmission lines is a serious problem in the power system. It not only affects the stability of power supply, but also may pose a threat to the safety of personnel and equipment.

[0044] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and implementation methods. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all of them.

[0045] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between 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.

[0046] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0047] In the description of this embodiment, the terms "upper", "lower", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplified operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0048] For example, the loss of distribution and transmission lines is a serious problem in the power system. It not only affects the stability of power supply, but also may pose a threat to the safety of personnel and equipment. There are many reasons for the loss of lines, including extreme weather conditions (such as strong winds, ice and snow, freezing rain, etc.), equipment aging (conductor corrosion, insulation aging), external factors (construction work, fallen trees, vehicle collisions, etc.) and equipment failures (loose joints, falling connections, etc.).

[0049] In the prior art, the lines are usually fixed to the pole towers by insulating cross arms, and the lines are suspended in the air. In addition, in the low temperature environment in winter, the lines will freeze, which will increase the weight of the lines, causing the weight to exceed the designed weight bearing limit, thus causing the lines to fall off. In addition, strong winds will also cause the lines to shake, causing the lines to fall off.

[0050] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure discloses a line anti-detachment device 100, which is arranged on a pole tower or other objects, and the line is arranged on the line anti-detachment device 100, so as to achieve the fixation of the line and the pole tower or other objects.

[0051] To solve the above problems, Figure 1 to Figure 3 As shown, the line anti-dropping device 100 includes a clamp 10, a clamping member 20 and a self-locking member 30. The clamp 10 has a accommodating space 12. The clamping member 20 and the self-locking member 30 are both arranged in the accommodating space 12 and located on the inner side of the clamp 10. The clamping member 20 and the self-locking member 30 can be used to clamp the line respectively. The clamping member 20 cooperates with the self-locking member 30. The axial movement of the clamping member 20 along the clamp 10 can enable the self-locking member 30 to clamp the line along the radial direction of the clamp 10. When the line shakes or falls off, the line drives the clamping member 20 to move axially along the clamp 10. The axial movement of the clamping member 20 can enable the self-locking member 30 to clamp the line along the radial direction of the clamp 10, thereby realizing the line anti-dropping device 100 to firmly clamp the line, which can effectively prevent the line from falling off.

[0052] In an optional embodiment, if Figure 3 and Figure 4 As shown, the clamping member 20 includes a first triggering portion 21 having a first inclined surface 211, and the self-locking member 30 includes a second triggering portion 31 having a second inclined surface 311. The first inclined surface 211 is in contact with the second inclined surface 311. The axial movement trend of the first inclined surface 211 relative to the second inclined surface 311 along the clamp 10 is converted into the second triggering portion 31 moving toward the axis L of the clamp 10 through the sliding of the first inclined surface 211 and the second inclined surface 311. c The movement trend in the direction can be realized by setting the simple structure of the first inclined surface 211 and the second inclined surface 311, so that the second trigger part 31 can firmly clamp the line. The first trigger part 21 and the second trigger part 31 are compactly arranged, and the movement trend can be quickly converted in a limited space, ensuring that the line anti-detachment device 100 occupies a smaller space, which is convenient for the better installation and use of the line anti-detachment device 100 in a limited space.

[0053] Specifically, if Figure 3 As shown, the first inclined surface 211 and the second inclined surface 311 are both aligned with the axis L of the hoop 10. cThe angle is set. Due to the setting of the angle, when the first inclined surface 211 and the second inclined surface 311 slide relative to each other, the force F exerted by the clamping member 20 on the self-locking member 30 合 It can be decomposed into a first force component F1 along the axial direction of the clamp 10 and a second force component F2 along the radial direction of the clamp 10 , wherein the second force component F2 can achieve the effect of the self-locking member 30 clamping the line along the radial direction of the clamp 10 .

[0054] In an optional embodiment, if Figure 3 As shown, the first trigger part 21 and the second trigger part 31 are matched with each other, the first trigger part 21 also includes a third inclined surface 212, and the second trigger part 31 also includes a fourth inclined surface 312. The third inclined surface 212 is in contact with the fourth inclined surface 312, and the fourth inclined surface 312 is in contact with the axis L of the clamp 10. c The second inclined surface 311 and the fourth inclined surface 312 are arranged at an angle along the axial direction of the clamp 10, and the distance between the second inclined surface 311 and the fourth inclined surface 312 gradually decreases along the radial direction and outward direction of the clamp 10. When the clamp 20 has a tendency to move to the left, the first inclined surface 211 and the second inclined surface 311 cooperate with each other, which can trigger the self-locking component 30 to clamp the line along the radial direction of the clamp 10; when the clamp 20 has a tendency to move to the right, the third inclined surface 212 and the fourth inclined surface 312 cooperate with each other, which can achieve the effect of triggering the self-locking component 30 to clamp the line along the radial direction of the clamp 10. In summary, the line anti-slip device 100 of this optional embodiment has the first inclined surface 211, the second inclined surface 311, the third inclined surface 212 and the fourth inclined surface 312 at the same time. The line drives the clamp 20 to move in any direction (either of the two directions), which can trigger the self-locking component 30 to lock the line.

[0055] In an optional embodiment, if Figure 3 and Figure 4 As shown, at least two first trigger parts 21 are provided, and at least two first trigger parts 21 are arranged in sequence along the axial direction of the clamp 10. By providing more first trigger parts 21 and second trigger parts 31, it is possible to ensure that the self-locking part 30 can firmly clamp the line at various axial positions of the clamp 10.

[0056] In an optional embodiment, if Figure 3 and Figure 4As shown, the clamping member 20 also includes a first clamping portion 22 and a connecting portion 23. The first clamping portion 22, the connecting portion 23 and the first triggering portion 21 are connected in sequence. The first clamping portion 22 is used to clamp the circuit. A through groove 111 is provided on the clamping hoop 10. The extending direction of the through groove 111 is arranged parallel to the axial direction of the clamping hoop 10. The connecting portion 23 is arranged in the through groove 111. The connecting portion 23 and the side wall of the through groove 111 are arranged at intervals along the radial direction of the clamping hoop 10. Through the arrangement of the through groove 111, the clamping member 20 can be ensured to move radially along the clamping hoop 10 and to move axially along the clamping hoop 10. In addition, through the cooperation of the connecting portion 23 and the through groove 111, it can also be ensured that the clamping member 20 is always well suspended on the clamping hoop 10 to prevent the clamping member 20 from separating and falling off from the clamping hoop 10.

[0057] In an optional embodiment, if Figure 1 to Figure 4 As shown, the first clamping portion 22 can be made of an anti-slip material, and the anti-slip material can be a rubber material, a polyurethane material, a PVC material, a mineral particle material, etc. The anti-slip material can further enhance the clamping effect of the clamping member 20 on the circuit and prevent the circuit from loosening. It should be noted that the aforementioned materials are only a limited list, and all materials with a high friction coefficient are within the protection scope of this optional embodiment, and all materials with a friction coefficient greater than or equal to 0.1 are within the protection scope of this optional embodiment.

The second clamping portion 33 is made of an anti-slip material. The anti-slip material can be a rubber material, a polyurethane material, a PVC material, a mineral particle material, etc. The anti-slip material can further enhance the clamping effect of the self-locking member 30 on the line and prevent the line from loosening.

The first limiting portion 113 cooperates with the second limiting portion 34 to limit the self-locking member 30 from being separated from the clamp 10. Through the cooperation between the first limiting portion 113 and the second limiting portion 34, it can be ensured that the self-locking member 30 is always well suspended on the clamp 10, thereby preventing the self-locking member 30 from separating and falling off from the clamp 10.

[0064] In an optional embodiment, if Figure 3 and Figure 4 As shown, the first clamping portion 22 is arc-shaped and is arranged around the outer circumference of the circuit.

[0066] In an optional embodiment, if Figure 1 and Figure 2 As shown, the clamp 10 includes two loop arms 11, which are detachably connected and are commonly arranged around the periphery of the line. When the two loop arms 11 are in a locked state, the two loop arms 11 cooperate to achieve the effect of fixing and clamping the line.

[0067] In an optional embodiment, if Figure 1 and Figure 2 As shown, the hoop 10 further includes a fixing member 15, each of the loop arms 11 includes a first end and a second end, the first ends of the two loop arms 11 are rotatably connected, and the second ends of the two loop arms 11 are fixedly connected through the fixing member 15, thereby realizing the rapid opening and locking function of the two loop arms 11, facilitating the fixing and separation of the line and the hoop 10, and facilitating the rapid assembly of the line and the hoop 10. Exemplarily, the two loop arms 11 can be rotatably connected through a hinge 13.

[0068] Exemplarily, the fixing member 15 can be a combination assembly of screws and nuts, a magnetic assembly, a snap assembly, a pin, etc. All fixing members 15 that can fix the two holding arms 11 are within the protection scope of this optional embodiment.

The line anti-slip device 100 has good versatility and can adapt to many usage scenarios.

[0072] In an optional embodiment, if Figure 1 to Figure 4 As shown, an air chamber 112 is provided in the clamp 10, and the driving mechanism 40 includes a pneumatic cylinder 41 and a gas generating mechanism (not shown in the figure). The pneumatic cylinder 41 includes a cylinder body 411 and a piston 412 which can move radially relative to the clamp 10, and the free end of the piston 412 can abut against the clamp 20. The cylinder body 411 is connected to the air chamber 112, and the gas generating mechanism is connected to the air chamber 112. The gas generating mechanism can generate gas, and the gas generating mechanism can achieve different degrees of extension of the piston 412 by adjusting the gas output, so that the driving mechanism 40 can achieve a better clamping effect on lines of different diameters or models.

[0073] In an optional embodiment, if Figure 1 to Figure 4 As shown, the drive mechanism 40 also includes an air pressure detection mechanism 43, which is connected to the air chamber 112. The air pressure detection mechanism 43 is used to detect the pressure of the gas in the air chamber 112. The user can judge whether the drive mechanism 40 has tightened and clamped the corresponding line according to the value displayed by the air pressure detection mechanism 43. Specifically, the line anti-slip device 100 can be tested before leaving the factory to give a preset value corresponding to the line clamping of the line anti-slip device 100. When the value displayed by the air pressure detection mechanism 43 has reached the preset value, it can be judged that the drive mechanism 40 has tightened and clamped the line, and the user can control the gas generating mechanism to stop working. Exemplarily, the air pressure detection mechanism 43 can be various types of barometers, and all types of barometers are within the protection scope of this optional embodiment.

[0075] In an optional embodiment, the driving mechanism 40 also includes a control mechanism, which is respectively communicated with the gas generating mechanism and the air pressure detection mechanism 43.

[0076] In an optional embodiment, if Figure 1 to Figure 4 As shown, the pneumatic cylinder 41 is fixedly connected to the clamp 10, and the overall integration of the line anti-detachment device 100 is good, which facilitates the rapid assembly of the line anti-detachment device 100 and the line.

[0077] In an optional embodiment, if Figure 1 to Figure 4 As shown, the air pressure detection mechanism 43 is fixedly connected to the clamp 10, and the overall integration of the line anti-detachment device 100 is good, which facilitates the rapid assembly of the line anti-detachment device 100 and the line.

[0078] For ease of understanding, combined Figure 1 to Figure 4 The working process of the line anti-drop device 100 is described below:

[0079] When in use, first clamp the ring arm 11 on the line, and after clamping, fix the two locking plates 14 by the fixing member 15, and then fix the fixing plate 16 to the pole tower and other objects. At this time, the clamping member 20 is clamped on the line, and the first anti-slip pattern 221 on the clamping member 20 can increase the friction between the clamping member 20 and the line. When the line moves or falls off, the line will drive the clamping member 20 to move along the axial direction of the clamp 10, and the clamping member 20 triggers the self-locking member 30 to move along the radial direction of the clamp 10, and the self-locking member 30 can clamp the line more firmly. The more the line is pulled, the greater the amplitude of movement of the clamping member 20, the greater the amplitude of movement of the self-locking member 30, and the greater the clamping force of the self-locking member 30 on the line, thereby achieving a better clamping effect of the self-locking member 30 on the line.

[0080] In addition, high-pressure gas can be added through the gas interface 45, and the high-pressure gas enters the cylinder body 411 after passing through the gas chamber 112, and the piston 412 is pushed out, and the piston 412 pushes out the clamping member 20, so that the clamping member 20 clamps the line, and the setting of the driving mechanism 40 can prevent the clamping member 20 from retracting. In addition, the setting of the air pressure detection mechanism 43 can prevent the line anti-dropping device 100 from failing to clamp due to air leakage.
