Description

Technical Field

[0001] The present invention relates to the technical field of electrical engineering de-icing, and particularly to a cable de-icing edge device. Background Art

[0002] In rural main lines, 120mm² aluminum core insulated cables (conductor diameter 13.5mm, about 18mm after insulation) are often used as transportation lines. After multiple cores of such cables are combined, they are thicker and longer. After snow in winter, vertical downward ice edges will appear on such cables after the snow melts. This will not only increase the weight load on the cable, but also the falling of the ice edges will affect the safety of residents. Conventional cable de-icing edge devices are often expensive and mainly applied to high-voltage transmission lines, that is, the existing de-icing edge devices are expensive and only applied to thick-diameter high-voltage cables.

[0003] Therefore, there is an urgent need for a de-icing edge device with low cost and suitable for rural main and branch lines. Summary of the Invention

[0004] In order to make up for the deficiencies in the prior art and achieve the above functions, the present invention provides a cable de-icing edge device.

[0005] The present invention is realized by the following technical solutions: A cable de-icing edge device includes an inverted "U"-shaped body. Inside the body, a "cross"-shaped rotating cavity and a driving cavity are respectively arranged front and back. A rotating mechanism capable of contacting the lower cable is installed in the rotating cavity, and a driving mechanism is installed in the driving cavity; The bottom of the body is a semi-circular arc cavity, and the top of the arc cavity is divided left and right by the rotating cavity and the driving cavity. A plurality of ball bearings are arranged on the left and right inner walls of the arc cavity; On the left and right sides of the bottom of the body, two anti-disengagement plates are rotatably connected. On the inner side of each anti-disengagement plate, an isosceles triangular anti-disengagement sheet metal is arranged, and the vertices of the two anti-disengagement sheet metals face each other; The rotating mechanism includes a front motor fixed in the rotating cavity. The rotating shaft of the front motor is matched with the front bearing seat on the opposite side, and an inner ring sleeve is fixed on the rotating shaft. Three pairs of brackets are evenly arranged on the left and right sides of the inner ring sleeve. A roller is installed on each pair of brackets, and the middle of the roller is concave. The three rollers are all wound by a conveyor belt, and the conveyor belt is connected to a transmission wheel in the driving mechanism. The conveyor belt is located at the concave part of the roller.

[0006] Further, the driving mechanism includes a rear motor and a rear bearing seat fixed in the driving cavity, and the transmission wheel is fixed on the output shaft of the rear motor.

[0007] Further, a brake is arranged on the front motor.

[0008] Further, a front counterweight and a rear counterweight are respectively arranged in the rotation cavity and the driving cavity, and heat dissipation slots are arranged on the left and right sides of the machine body corresponding to the positions of the rotation cavity and the driving cavity.

[0009] Further, inclined plates are installed at the lower positions on both sides of the machine body and a plurality of limiting cylinders are arranged on the inclined plates. A spring is arranged in each limiting cylinder, and the other end of the spring extends into a corresponding limiting hole on the anti - detachment plate, and the limiting hole corresponds to the direction of the limiting cylinder.

[0010] Further, when the spring is in a relaxed state, the anti - detachment plate is in a vertical state.

[0011] Further, the machine body is made of plastic material, and an energy supply module and a control module are arranged between the rotation cavity and the driving cavity.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present invention.

[0018] Reference Figures 1 to 5 , including an inverted "U"-shaped body 1. Inside the body 1, a "cross"-shaped rotating cavity 101 and a driving cavity 104 are respectively arranged in the front and rear. A rotating mechanism capable of contacting the cable below is installed in the rotating cavity 101, and a driving mechanism is installed in the driving cavity 104; The bottom of the body 1 is a semi-circular arc cavity 102 for accommodating the cable. The top of the arc cavity 102 is divided left and right by the rotating cavity 101 and the driving cavity 104. A number of balls 2 are arranged on the left and right inner walls of the arc cavity 102. The balls 2 are in contact with the cable to keep the balance of the machine during operation, and the balls 2 will make point contact with the cable, thus avoiding the friction caused by the direct surface contact between the cable and the arc cavity 102; Two anti-drop plates 3 are rotatably connected to the left and right sides of the bottom of the body 1. An isosceles triangular anti-drop sheet metal 301 is arranged inside each anti-drop plate 3, and the vertices of the two anti-drop sheet metals 301 face each other. When the drone places this device on the cable, the hypotenuses of the two anti-drop sheet metals 301 will be squeezed and separated, which is beneficial for the cable below to enter; The rotating mechanism includes a front motor 4 fixed in the rotating cavity 101. The rotating shaft of the front motor 4 is matched with the front bearing seat 404 on the opposite side, and an inner ring sleeve 401 is fixed on the rotating shaft. Three pairs of brackets 402 are evenly arranged on the left and right sides of the inner ring sleeve 401. A roller 403 is installed on each pair of brackets 402, and the middle of the roller 403 is concave. The three rollers 403 are all wound by a conveyor belt 6, and the conveyor belt 6 is connected to the transmission wheel 501 in the driving mechanism, that is, the transmission wheel 501 will make the roller 501 rotate through the conveyor belt 6. The conveyor belt 6 is located in the concave part of the roller 403.

[0019] The driving mechanism includes a rear motor 5 and a rear bearing block 502 fixed in the driving cavity 104, and a transmission wheel 501 is fixed on the output shaft of the rear motor 5.

[0020] A brake 405 is provided on the front motor 4. When the device runs on the cable, the output shaft of the front motor 4 is braked, and the roller 403 rotates freely.

[0021] A front counterweight 7 and a rear counterweight 8 are respectively arranged in the rotating cavity 101 and the driving cavity 104. The front counterweight 7 and the rear counterweight 8 evenly distribute the weight of the whole body 1 in the front-back and left-right directions to prevent tilting when hanging on the cable line.

[0022] Heat dissipation slots 103 are arranged on the left and right sides of the body 1 corresponding to the positions of the rotating cavity 101 and the driving cavity 104 for dissipating heat from internal components during travel.

[0023] Slant plates 9 inclined outward are installed at the lower positions on both sides of the body 1, and a plurality of limiting cylinders 901 are arranged on the slant plates. A spring 902 is arranged in each limiting cylinder 901. The limiting cylinder 901 prevents the spring 902 from skewing. The other end of the spring 902 extends into a corresponding limiting hole 903 on the anti-detachment plate 3, and the limiting hole 903 corresponds to the direction of the limiting cylinder 901.

[0024] When the spring 902 is in a relaxed state, the anti-detachment plate 3 is in a vertical state, that is, the anti-detachment plate 3 is pushed open and separated and reset by the spring 902 to provide a certain supporting force.

[0025] The body 1 is made of plastic material to reduce the weight of the whole machine. An energy supply module and a control module are arranged between the rotating cavity 101 and the driving cavity 104.

[0026] The working principle of the present invention is as follows: The present invention is carried by a drone at the top. After the cable is sleeved into the arc cavity 102 of the present machine by using two elastic anti-detachment sheet metals 301 protruding inward, due to different diameters of different cable lines, when in a horizontal state, it abuts against different balls 2, and it cannot ensure that it completely contacts the edge of the roller 403. Normally, as Figure 2 shown, two rollers 403 are in contact with the cable line. Under appropriate circumstances, the brake 405 is closed, the front motor 4 rotates, and then a single roller 403 faces downward. At this time, the contact height will be reduced, prompting the single roller 403 to abut against the cable line with the ball 2. Then the brake 405 is opened, and only by the rotation of the transmission wheel 501, the three rollers 403 rotate by themselves to drive the present machine to move forward. Since the apex spacing of the anti-detachment sheet metal 301 is small and it is made of sheet metal, when facing ice ridges, the present machine moving at high speed is sufficient to knock open the ice ridges at the bottom of the cable to achieve the effect of removing ice ridges.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
