[0039] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "vertical", "horizontal", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" used in the present invention to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" 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 an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1 to Figure 7 As shown, a drainage clamp according to a preferred embodiment of the present invention comprises a contact wire clamp 1, a conducting portion 2 and an insulating handle 3;

[0043] The contact wire clamp 1 is provided with a hooking portion 11 for hooking the high-voltage wire and a connecting portion 12 for connecting the conductive cable 4, the front end of the conductive portion 2 is connected to the connecting portion 12, and the rear end of the conductive portion 2 is connected to the conductive cable 4, the insulating handle 3 is sleeved on the outer periphery of the contact wire clamp 1 and the conductive portion 2, and the insulating handle 3 is movably connected to the contact wire clamp 1 so as to be able to move along the axial direction of the contact wire clamp 1 to press against and fix the high-voltage wire.

[0044] The working process of the present invention is as follows: the hooking portion 11 hooks the high-voltage line outlet, and then the insulating handle 3 is rotated so that the front end of the insulating handle 3 abuts against the high-voltage line outlet, so that the high-voltage line outlet is fixed to the hooking portion 11. Since the connecting portion 12 of the contact wire clamp 1 is conductive, the current at the high-voltage line outlet flows from the contact wire clamp 1 to the connecting portion 2, and since the rear end of the conductive portion 2 is connected to the conductive cable 4, the current flows from the conductive portion 2 to the conductive cable 4.

[0045] The high-voltage line outlet is directly hooked through the hooking part 11, and the front end of the insulating handle 3 abuts against the high-voltage line outlet, which simplifies the complex steps of connecting the high-voltage line outlet and the emergency connection cable through the copper nose in the traditional connection, thereby improving the installation efficiency. In addition, the current passes through the high-voltage line outlet to the contact wire clamp 1, the conductive part 2, and the conductive cable 4, ensuring that the high-voltage overhead line can be powered uninterruptedly. The insulating handle 3 can insulate the conductive part 2 and the contact wire clamp 1, play a role in electrical isolation, effectively prevent the conductive part 2 and the contact wire clamp 1 from contacting the outside world and leaking electricity, and ensure the safety of construction personnel during the construction process.

[0046] Preferably, the drain clamp also includes a movable pressing block 32, which is movably sleeved on the outer periphery of the contact clamp 1, and the insulating handle 3 is sleeved on the outer periphery of the movable pressing block 32. When the insulating handle 3 moves axially along the contact clamp 1, it can push the movable pressing block 32 to abut against the high-voltage line; the insulating handle 3 is threadedly connected to the contact clamp 1. The movable pressing block 32 is rotatably connected to the contact line through a threaded connection. Since the threaded connection has a self-locking property, even under the action of external forces, such as slight movement of the cable caused by wind, the threaded connection can provide stable axial and radial pressure to ensure the stability of the connection between the drain clamp and the outlet terminal of the high-voltage line. The front end of the movable pressing block 32 abuts against the outlet terminal of the high-voltage line. In this embodiment, the outer periphery of the insulating handle 3 is silicone rubber, and the movable pressing block 32 is made of hard material, which is convenient for fixing the outlet terminal of the high-voltage line to the hook portion 11.

[0047] Preferably, the front end of the contact wire clamp 1 is connected with an insulating cap 5. The insulating cap 5 can provide electrical isolation, ensuring that the front end of the contact wire clamp 1 does not directly contact the external environment, thereby preventing leakage and electric shock accidents, and thus the insulating cap 5 makes the contact wire clamp 1 easier to operate during installation, because construction workers can handle the contact wire clamp 1 more confidently without worrying about the risk of electric shock.

[0048] Preferably, the rear end of the contact wire clamp 1 is provided with a mounting groove 13, the front end of the conductive part 2 penetrates into the mounting groove 13 and is threadedly connected to the contact wire clamp 1, the installation between the conductive part 2 and the contact wire clamp 1 is simple and the threaded connection has high reliability.

[0049] Preferably, the outer peripheral surface of the insulating handle 3 is fixedly sleeved with an insulating ring 31 protruding in the radial direction thereof. Electric flashover occurs through the air medium, but since the curve of the distribution of electric field lines in the air is close to the number of electric field lines around the insulating handle 3, electric flashover is more likely to occur here. The insulating ring 31 protrudes outward along the circumference of the insulating handle 3, and the insulating ring 31 can block the electric field lines around the insulating handle 3, thereby reducing the probability of electric flashover.

[0050] An installation tool, used for installing any of the above drainage wire clamps, comprising: a mounting seat 9, a fixed portion 6 and a rotating portion 7 rotatably connected to the mounting seat 9, the fixed portion 6 being transmission-connected to the rotating portion 7;

[0051] The fixing portion 6 is provided with a clamping space 611 , and the fixing portion 6 is used to fix the insulating handle 3 in the clamping space 611 . Rotating the rotating portion 7 can drive the fixing portion 6 to rotate accordingly.

[0052] The working process of the embodiment of the present invention is as follows: the operator first fixes the insulating handle 3 in the clamping space 611, and then rotates the rotating part 7, so that the fixed part 6 rotates with the rotating part 7, so that the front end of the insulating handle 3 abuts against the high-voltage line outlet, and the high-voltage line outlet is fixed to the hook part 11. By fixing and using the insulating handle 3 by the fixed part 6 and the rotating part 7, the operator can maintain a safe distance from the cable and the wire clamp during the operation, avoiding the risk of direct electric shock.

[0053] Preferably, the fixing part 6 comprises a fixing column 61, a limiting block 62, a fixing clamp 63 and a mounting block 64; there are multiple fixing columns 61, and the multiple fixing columns 61 enclose a clamping space 611, the limiting block 62 is fixedly connected to the top of the multiple fixing columns 61, the mounting block 64 is fixedly connected to two adjacent fixing columns 61, the fixing clamp 63 is threadedly connected to the mounting block 64, and the fixing clamp 63 cooperates with the limiting block 62 to clamp and fix the insulating handle 3 in the clamping space 611. The multiple fixing columns 61 enclose a clamping space 611 that can accommodate and fix the insulating handle 3, and the limiting block 62 is fixedly connected to the top of the multiple fixing columns 61, and the limiting block 62 plays a role in limiting the insulating handle 3 from moving out of the clamping space 611, thereby ensuring the stability and safety of the handle in the clamping space 611.

[0054] Preferably, the rotating part 7 includes: a driving gear 71, a driven gear 72 and a driving shaft 73, and the mounting seat 9 includes: a top plate 91 and a bottom plate 92;

[0055] The driving shaft 73 is fixedly connected to the driving gear 71. The driving gear 71 rotates to drive the driven gear 72 to rotate. The diameter of the driving gear 71 is smaller than that of the driven gear 72. The top plate 91 and the bottom plate 92 are arranged at intervals and connected by bolts. The driving gear 71 and the driven gear 72 are arranged between the top plate 91 and the bottom plate 92 and are rotatably connected to the top plate 91 and / or the bottom plate 92. The fixing column 61 is fixedly connected to the driven gear 72. The corresponding clamping spaces 611 of the driven gear 72 and the bottom plate 92 are both provided with clamping grooves. The specific working process of the rotating part 7 is as follows: the operator rotates the driving shaft 73, the driving shaft 73 rotates to drive the driving gear 71 to rotate, the driving gear 71 rotates to drive the driven gear 72 to rotate, and since the fixing column 61 is fixedly connected to the driven gear 72, the driven gear 72 rotates to drive the fixing column 61 to rotate, and the fixing column 61, the limit block 62 and the fixing clamp 63 cooperate to fix the insulating handle 3, so that the operator rotates the driving shaft 73, that is, the insulating handle 3. Furthermore, the diameter of the driving gear 71 is smaller than that of the driven gear 72 , so that the driven gear 72 can obtain a larger rotational torque under the same driving force, thereby making it easier to drive the insulating handle 3 , thereby achieving the purpose of easily and conveniently rotating the insulating handle 3 .

[0056] Preferably, the driven gear 72 is provided with a fixing groove 721 which passes through its axis and has an opening on the outer wall. The rotating part 7 also includes a first gear 74 and a second gear 75. The diameters of the first gear 74 and the second gear 75 are the same. The diameter of the first gear 74 is larger than the diameter of the driving gear 71 and smaller than the diameter of the driven gear 72. The top plate 91 is rotatably connected to the first gear 74 and the second gear 75 is arranged between the top plate 91 and the bottom plate 92, and is rotatably connected to the top plate 91 and / or the bottom plate 92. The first gear 74 and the second gear 75 are arranged at intervals, and both the first gear 74 and the second gear 75 are meshed with the driving gear 71, and the driven gear 72 is meshed with the first gear 74 and / or the second gear 75; the driving gear 71 drives the driven gear 72 to rotate by driving the first gear 74 and the second gear 75.

[0057] The specific working process of this embodiment is as follows: when the operator rotates the drive shaft 73, the drive shaft 73 drives the driving gear 71 to rotate, and the rotation of the driving gear 71 drives the first gear 74 and the second gear 75 to rotate at the same time, and the rotation of the first gear 74 and the second gear 75 drives the driven gear 72 to rotate respectively. Since the driven gear 72 has a fixed groove 721, the interval between the first gear 74 and the second gear 75 ensures that the driven gear 72 is engaged with the first gear 74 or the second gear 75 even when the first gear 74 or the second gear 75 is located in the fixed groove 721, so that the transmission is realized. The fixed column 61 is fixedly connected to the driven gear 72, so the rotation of the driven gear 72 drives the fixed column 61 to rotate. The insulating handle 3 passes through the clamping space 611 and the fixed groove 721 in sequence, and the fixed column 61, the limit block 62 and the fixed clamp 63 (for fixing the insulating handle 3) work together to ensure that the insulating handle 3 remains stable during the rotation process. Through the first gear 74 and the second gear 75, the stability and reliability of the rotation are enhanced, and the efficiency of the transmission is improved.

[0058] Preferably, the rotating part 7 also includes an adjustment mechanism 8, which includes a first mounting shell 81, a second mounting shell 82, a first connecting shaft 83, a second connecting shaft 84 and a connecting rod 85; the top of the first mounting shell 81 abuts the bottom plate 92, the first mounting shell 81 and the second mounting shell 82 jointly form an installation space, the first connecting shaft 83 is connected to the first mounting shell 81 and is arranged in the installation space, the second connecting shaft 84 is connected to the second mounting shell 82 and is arranged in the installation space, one end of the first connecting shaft 83 is fixedly connected to the drive shaft 73, the other end of the first connecting shaft 83 is rotatably connected to the second connecting shaft 84, and the second connecting shaft 84 is fixedly connected to the connecting rod 85. The specific working process of this embodiment is: the staff drives the second connecting shaft 84 to rotate by rotating the connecting rod 85, the torque of the second connecting shaft 84 can drive the first connecting shaft 83 to rotate, the rotation of the first connecting shaft 83 causes the drive shaft 73 to rotate, and the operator can achieve the effect of rotating the insulating handle 3 on the ground. The other end of the first connecting shaft 83 is rotatably connected to the second connecting shaft 84. By fine-tuning the position or angle of the connecting rod 85, the operator can also adjust the angle of the first connecting shaft 83 through the connecting rod 85 on the ground to ensure that the high-voltage line outlet end can be firmly fixed to the hook portion 11. Since high-altitude operations are avoided, that is, the occurrence of high-altitude falling accidents is avoided, the safety of the operator is further guaranteed while the high-voltage line can be supplied with uninterrupted power.

[0059] In summary, the embodiment of the present invention provides a high-voltage cable quick and safe connection drainage clamp and installation tool, which directly hooks the high-voltage line outlet through the hook portion 11, and the front end of the insulating handle 3 abuts the high-voltage line outlet, which simplifies the complex steps of connecting the high-voltage line outlet and the emergency connection cable through the copper nose in the traditional connection, thereby improving the installation efficiency. In addition, the current passes through the high-voltage line outlet to the contact wire clamp 1, the conductive part 2, and the conductive cable 4, ensuring that the high-voltage overhead line can be powered uninterruptedly. The insulating handle 3 can insulate the conductive part 2 and the contact wire clamp 1, which plays a role in electrical isolation, effectively preventing the conductive part 2 and the contact wire clamp 1 from contacting the outside world and leaking electricity, and ensuring the safety of construction personnel during the construction process.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
