In addition, specific terms can be selected by the applicant, and in this case, the detailed meaning thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meaning of the terms and the overall description of the present application.
[0027] Referring to Figures 1 to 5 , the present embodiment provides a power line explosion mechanism, comprising,
[0028] The receiving and releasing assembly 1 comprises a lowering part 11, and a hook releasing part 12 is arranged on the lowering part 11;
[0029] The suspension assembly 2 is detachably connected with the hook releasing part 12 and the receiving and releasing assembly 1, and the suspension assembly 2 comprises a cross-line frame 21, the cross-line frame 21 has an opening 22 facing downward, the cross-line frame 21 is suspended on the power line through the opening 22, and a containing part 23 is arranged on the cross-line frame 21;
[0030] The explosion assembly 3 is arranged in the containing part 23.
[0031] The explosion principle of the transmission line explosion mechanism is as follows: the explosion assembly 3 is placed in the containing piece 23, then the suspension assembly 2 is connected together through the unhooking piece 12 and the receiving and releasing assembly 1, the receiving and releasing assembly 1 is fixed on the transportation equipment, such as a unmanned aerial vehicle 4 or a hoisting equipment, the whole explosion mechanism is transported to the upper part of the transmission line through the transportation equipment, then the lowering piece 11 performs the lowering work, the unhooking piece 12 is lowered together with the suspension assembly 2, until the cross-line frame 21 is suspended on the transmission line, then the unhooking piece 12 is opened, the connection between the unhooking piece 12 and the suspension assembly 2 is released, then the lowering piece 11 performs the recycling work, the unhooking piece 12 is lifted back to the position before lowering, then the transportation equipment works to transport the receiving and releasing assembly 1 back to the ground, the suspension assembly 2 stays on the transmission line together with the explosion assembly 3, then the explosion assembly 3 is ignited, the explosion force of the explosion assembly 3 acts on the cross-line frame 21, and the cross-line frame 21 acts on the transmission line in contact with the cross-line frame 21, so that the transmission line is exploded.
[0032] Referring to Figure 2 In some embodiments, the opening 22 on the cross-line frame 21 is gradually narrowed from bottom to top, and the top end of the opening 22 is pointed.
[0033] When the suspension assembly 2 is lowered, the transmission line gradually enters the inside of the opening 22 from the lower end of the opening 22 to the upper end position, until the transmission line contacts the inner wall of the top end of the opening 22, the suspension of the cross-line frame 21 is realized. The opening 22 is designed to be wide at the lower part and narrow at the upper part, the transmission line is easier to enter the lower part of the opening 22, and the top end of the transmission line is pointed, so that the side of the transmission line after suspension can be in contact with the side wall of the top end of the opening 22, forming a certain mutual limiting action, which can limit the movement of the cross-line frame 21 and improve the firmness after suspension. In order to further improve the firmness of the cross-line frame 21 after suspension, the cross-line frame 21 is in the shape of “∧”, and the two sides are designed symmetrically. When suspended, the two sides of the cross-line frame 21 are arranged on the two sides of the transmission line. Due to the symmetrical design of the two sides and the gravity center of the cross-line frame 21 at the top point, the stability after suspension is good, and it is not easy to tilt and fall. Of course, the angle between the two sides of the cross-line frame 21 also has an influence on the stability after suspension. When designing, the angle between the two sides of the cross-line frame 21 is preferably designed to be small, such as 45°, on the premise of ensuring that the lower end of the opening 22 is easy for the transmission line to enter.
[0034] In order to prevent the cross-line frame 21 from being heavy at the head and light at the foot (easy to tilt and fall), the lower end positions of the two sides of the cross-line frame 21 are fixedly provided with feet, which also facilitates standing when placing. The feet are in the shape of a cylinder and have a certain length. In order to reduce the weight of the cross-line frame 21, the overall weight of the cross-line frame 21 is not easy to be too large. The cross-line frame 21 can be made of wood or plastic, or light metal, such as aluminum alloy.
[0035] The accommodating member 23 is arranged at the top end of the cross-line frame 21, specifically, the accommodating member 23 is arranged parallel to the power transmission line, and the top end of the accommodating member 23 is fixedly provided with a connecting rope 24, one end of the connecting rope 24 away from the accommodating member 23 is detachably connected to the unhooking member 12.
[0036] Under the premise that the cross-line frame 21 is designed as an “∧” type, the accommodating member 23 is designed at the top end position of the cross-line frame 21, and the advantage of this design is that, since the power transmission line is in contact with the inner top end of the cross-line frame 21, after the explosive assembly 3 is placed in the accommodating member 23, the explosive assembly 3 is very close to the power transmission line, and when the explosive assembly 3 explodes, the power transmission line can be subjected to a greater impact force, thereby ensuring the explosion effect, and at the same time, due to the “∧” type design of the cross-line frame 21 and the position design of the accommodating member 23, the power transmission line is located directly below the explosive assembly 3, and the impact force of the explosive assembly 3 explosion is positively downward on the power transmission line, reducing lateral dispersion, further ensuring a greater impact force, thereby ensuring the explosion effect.
[0037] Referring to Figure 2 In an embodiment provided in the present application, the accommodating member 23 is in a cylindrical shape, and at least one end of the accommodating member 23 is open.
[0038] The explosive such as detonator is generally in a cylindrical shape, and the accommodating member 23 is in a cylindrical shape, which is suitable for most explosive products, and when the accommodating member 23 is designed, the length thereof must be greater than that of the explosive assembly 3, so that the explosive assembly 3 can be completely placed in the accommodating member 23, that is, the side wall of the accommodating member 23 completely wraps the side wall of the explosive assembly 3, thereby preventing the lateral splashing of the explosion from hitting the power transmission line and causing damage to the power transmission line.
[0039] Referring to Figure 1 and Figures 3 to 5 In some embodiments, the winding and releasing assembly 1 further comprises a device box 13, the lowering member 11 comprises a winch 111 arranged in the device box 13, the winch 111 is wound with a lowering rope 112, the lower end of the lowering rope 112 is arranged outside the device box 13, and the unhooking member 12 is fixed to the lower end of the lowering rope 112; the bottom of the device box 13 is provided with a through hole 14 through which the lowering rope passes, a contact switch 15 is arranged at the through hole 14, the contact switch 15 is connected with the winch 111, and the lower end of the lowering rope 112 is fixed with a blocking cap 16, and the blocking cap 16 is located at the upper portion of the unhooking member 12.
[0040] The specific lowering process is that the winch 111 performs a rope releasing action, and due to the action of gravity, the suspension assembly 2 at the lower end of the lowering rope 112, the unhooking piece 12 and the explosive assembly 3 move downward together until the cross line frame 21 is arranged on the power transmission line, then the unhooking piece 12 is opened, the connecting rope 24 is separated from the unhooking piece 12, and then the suspension assembly 2 and the winding and releasing assembly 1 are separated, and then the winch 111 performs a rope winding action, the lowering rope 112 rises together with the blocking cap 16 and the unhooking piece 12, when the blocking cap 16 rises to the position of touching the contact switch 15, the contact switch 15 controls the winch 111 to stop working, so as to avoid the situation that the unhooking piece 12 is blocked at the lower part of the equipment box 13 and is difficult to rise, and the winch 111 continues to work, which leads to the situation that the lowering rope 112 is pulled off or even the winch 111 is burned out. By this way, the winding work of the winch 111 is stopped, compared with the operation of the operator stopping at the lower part, the advantage is that: since the power transmission line is generally high, the operator at the lower part cannot clearly see the winding situation, which easily leads to the problem that the winch 111 is stopped too early or too late, too early generally has no impact, but too late may lead to the situation that the lowering rope 112 is pulled off or even the winch 111 is burned out.
[0041] The unhooking piece 12 is provided with a blocking rod 17, and the upper end of the connecting rope 24 is provided with a hanging plate 25, the hanging plate 25 is arranged on the blocking rod 17, when the winding and releasing assembly 1 and the suspension assembly 2 are connected, the unhooking piece 12 is in a closed state, the hanging plate 25 is hung on the cross rod, the blocking rod 17 is in a horizontal state, the two sides of the blocking rod 17 are blocked by the shell of the unhooking piece 12, the hanging plate 25 is difficult to separate from the cross rod, and the connection is realized, when the winding and releasing assembly 1 and the suspension assembly 2 are separated, the unhooking piece 12 is in an open state, the cross rod is rotated downward along one end, so that a space is left between the cross rod and the shell of the unhooking piece 12 for the hanging plate 25 to slide out, with the unhooking piece 12 being pulled upward by the lowering rope 112, the hanging plate 25 slides downward along the cross rod and finally separates from the cross rod, and the unhooking piece 12 specifically adopts a commercially available wireless remote control unhooking device.
[0042] In some embodiments, the explosive assembly 3 includes an electronic detonator 31, and the explosion force is selected to be about 70 kilograms, in actual application, the electronic detonator 31 can be wrapped with paper outside, so that the thickness of the electronic detonator 31 is basically the same as the inner diameter of the accommodating piece 23, so that the electronic detonator 31 is tightly contacted with the inner wall of the accommodating piece 23 after being inserted into the accommodating piece 23, which can not only avoid falling, but also improve the force transmission effect, and then improve the explosion effect.
[0043] Reference Figures 6 to 8 In an embodiment provided in the present application, a power transmission line deicing device includes a power transmission line explosion mechanism, and further includes,
[0044] The unmanned aerial vehicle 4, and the winding and releasing assembly 1 is fixed on the unmanned aerial vehicle 4.
[0045] Of course, it also includes remote control, the controller of the winch 111 is arranged in the equipment box 13, the unhooking device 12 adopts a wireless remote control unhooking device, the explosion assembly 3 adopts an electronic detonator 31, the remote control and the unmanned aerial vehicle 4, the winch 111, the wireless remote control unhooking device and the electronic detonator 31 are connected, the actions of these components are controlled, of course, the stop of the winch 111 when winding the rope is controlled through the upper contact switch 15.
[0046] The operator controls the operation through the remote control on the ground, and the lifting of the whole set of equipment, the cross setting of the suspension assembly 2, and the subsequent winding and explosion of the explosion assembly 3 can be completed, and the shock wave ice removal is realized, the whole shock wave ice removal process is relatively simple to operate, and the safety is good, since the explosion assembly 3 is directly arranged above the power transmission line, the impact force on the power transmission line during explosion is strong, the shock wave effect is guaranteed, and the ice removal effect is guaranteed, at the same time, through the structural design of the cross line frame 21, the cross line frame 21 can directly carry the explosion assembly 3 to cross the power transmission line, without the need of other components for position fixing, and the lowering and suspension of the cross line frame 21 can be completed through the winding and unwinding assembly 1, the structure is very simple, the operation is very convenient, and the shock wave ice removal effect is very good.
[0047] Finally, it should be pointed out that the above detailed description of the method and device is only an embodiment, and those skilled in the art can modify the embodiment in different ways without departing from the scope of the present application.
