Description

TECHNICAL FIELD

[0001] The utility model belongs to the cable deicing technical field, specifically, the utility model relates to a kind of overhead cable deicing device. BACKGROUND

[0002] Current overhead cable deicing methods include current melting method and mechanical deicing method.

[0003] Current melting method includes increasing load current and applying short-circuit current. Increasing load current by reversing load is suitable for initial icing, but it is not suitable for long-term use. Applying short-circuit current for ice melting (direct current ice melting) has high efficiency, but it cannot avoid user power outage.

[0004] Mechanical deicing methods currently include three types. First, the equipment cannot move autonomously along the wire, and needs to be pulled by manpower. For example, deicing is performed using tools such as long insulating rods, moisture-proof insulating ropes, and pulley-mounted deicers, and deicing is performed using insulating boom trucks with short poles. The efficiency is relatively low, and the risk is relatively high. Second, various robot devices can autonomously walk along the wire to deice. Some devices have complex structures, some devices have low practicality, and some devices are not easy to operate. Third, deicing is performed by unmanned aerial vehicles impacting with weights. This method is not suitable for removing frozen rain type icing (with tight adhesion), and requires high operation of unmanned aerial vehicle pilots.

The first deicing rod is connected to the rotating wheel through a first crank mechanism, and the second deicing rod is connected to the rotating wheel through a second crank mechanism. The utility model improves deicing efficiency by arranging the first deicing rod and the second deicing rod, connecting the first deicing rod to the transmission wheel through the first crank mechanism, connecting the second deicing rod to the rotating wheel through the second crank mechanism, and reciprocating the first deicing rod and the second deicing rod under the driving of the rotating wheel to sequentially contact and remove the ice on the cable.

DETAILED DESCRIPTION

[0025] The specific embodiments of the utility model are further described in detail by comparing the drawings and the embodiments, the purpose is to help the technical personnel in the field to have more complete, accurate and deep understanding to the conception, technical scheme of the utility model, and help to implement.

[0026] It should be noted that in the following embodiments, the "first" and "second" do not represent the absolute division relationship of structure and / or function, nor represent the execution order, but only for the convenience of description.

[0027] As Figures 1 to 3 shown, the utility model provides a kind of overhead cable deicing device, including base, walking mechanism being set on base, deicing execution mechanism being set on base and residual ice removing mechanism being set on walking mechanism, deicing execution mechanism includes two opposite arrangement support seat 87 and deicing unit being set on support seat 87, deicing unit is set multiple, all deicing units on support seat 87 are sequentially arranged and equidistantly distributed along the length direction of support seat 87, deicing unit includes the deicing claw 5 of movable setting on support seat 87 and the first spring of the elastic force applied to deicing claw 5.

[0028] Specifically, as Figure 1As shown, the deicing actuator further comprises a first motor 11 fixedly arranged on the base, a cam 10 connected with the first motor 11, and two followers matched with the cam 10. The two followers are arranged in an X shape and are connected with the two support seats 87 respectively. The cam 10 is fixedly connected with the motor shaft of the first motor 11. The two followers are rotatably arranged on the base through the pin 9. One end of each follower is in contact with the cam 10, and the other end of each follower is fixedly connected with the lower end of the support seat 87. The two followers are rotatably connected at the positions between the two ends through the pin 9. The positions between the two ends of each follower are provided with through holes through which the pin 9 passes. The cam mechanism serves as a driving mechanism for deicing. The working frequency is high, and the structure is simple without the need for a complicated movement in advance. The first motor 11 drives the two support seats 87 to swing through the cam mechanism. The deicing units on the two support seats 87 are matched to clamp and crush the ice layer on the cable. Through the driving of the walking mechanism, the deicing device is driven to travel along the cable, and the left and right reciprocating movement of the deicing claws 5 removes the accumulated ice on the cable.

[0029] In order to prevent the deicing device from being stuck due to too much resistance of the accumulated ice on the cable during the working process, thereby causing the motor to overheat and be damaged, an obstacle-avoiding deicing mechanism is specially designed. The first spring is arranged to enable the deicing claws 5 to be retractable. When encountering a larger resistance, the automatic retraction of the deicing claws 5 enables the cam mechanism to continue to work at a continuous high frequency to remove the ice, thereby increasing the service life of the deicing machine while ensuring the high-speed deicing effect.

[0030] As shown in FIGS. Figure 1 and Figure 2 The axis of the cam 10 is parallel to the length direction of the support seat 87. The two support seats 87 are arranged on the same straight line perpendicular to the length direction of the support seat 87. The cable is located between the two support seats 87. The support seat 87 is provided with a mounting hole for accommodating the deicing claw 5 and the first spring. One end of the deicing claw 5 is located in the mounting hole (the maximum outer diameter of this end of the deicing claw 5 is greater than the diameter of the mounting hole, and a stepped surface is formed at this end of the deicing claw 5). The other end of the deicing claw 5 is located outside the mounting hole. The deicing claw 5 is used to contact the ice layer on the cable. The first spring is used to apply an elastic force to the deicing claw 5 to make it extend outward from the support seat 87. The first spring is a cylindrical helical spring and a compression spring. The first spring is clamped between the end surface of the deicing claw 5 and the inner wall surface of the mounting hole. The moving direction of the deicing claw 5 is perpendicular to the length direction of the support seat 87 and the length direction of the cable.

[0031] The deicing unit with the above structure can automatically retract the deicing claw 5 into the mounting hole when encountering thicker accumulated ice, thereby achieving automatic obstacle avoidance. The special design of the deicing claw 5 can effectively protect the cable and increase the deicing efficiency.

[0032] As Figure 1 shown, the walking mechanism includes a driving wheel 16, a guide wheel 2 arranged side by side with the driving wheel 16, a driving mechanism connected with the driving wheel 16, a supporting wheel 17 arranged opposite to the driving wheel 16, and a supporting mechanism providing elastic supporting force to the supporting wheel 17. The driving mechanism includes a second motor 24 arranged on the base and a power transmission mechanism connected with the second motor 24, and the power transmission mechanism is connected with the driving wheel 16.

[0033] As Figure 1 shown, in the embodiment, the power transmission mechanism includes a first transmission mechanism 23 and a second transmission mechanism, the first transmission mechanism 23 is a gear transmission mechanism, the first transmission mechanism 23 plays a role of deceleration, and the second transmission mechanism is a belt transmission mechanism. The input end of the first transmission mechanism 23 is connected with the motor shaft of the second motor 24, the driving pulley 22 of the second transmission mechanism is connected with the output end of the first transmission mechanism 23, and the driven pulley 14 of the second transmission mechanism is connected together through a driving shaft at one end of the driving wheel 16 and connected together through a driving shaft and a bearing support 15 at the other end.

[0034] When the second motor 24 works, a certain power torque is output, the torque is increased through the deceleration of the first transmission mechanism 23, and finally the output force is applied to the driving wheel 16 through the transmission of the second transmission mechanism. Under the guidance of the guide wheel 2, the deicing device can walk, the first motor 11 drives the cam 10 to rotate, and then drives the left and right reciprocating movement of the deicing claw 5 to remove the accumulated ice on the high-voltage line.

[0035] As Figure 1 shown, the base is provided with an upper support 1, a lower support 21, a fixing frame 12 and a side connecting plate 13, and the first motor 11 is fixedly installed on the lower support 21. The upper support 1 is installed together with the lower support 21 through screws, the guide wheel 2 is installed on the upper support 1, the residual ice removing mechanism is installed in front of the guide wheel 2, the guide wheel 2 serves as a guide, and the residual ice removing mechanism is mainly used for removing residual ice on the cable. The fixing frame 12 is installed on the lower support 21 through screws, and the second motor 24 is installed on the lower support 21.

[0036] As Figure 1As shown, the support mechanism includes a support frame 18, a guide rod mounted on a base, and a second spring 19 sleeved on the guide rod and exerting an elastic force on the support frame 18. The support wheel 17 is mounted on the support frame 18. The drive wheel 16 and the guide wheel 2 are in contact with the cable. The drive wheel 16 and the guide wheel 2 are arranged in sequence along the length of the cable. The cable is clamped between the drive wheel 16 and the support wheel 17. The support wheel 17 is located below the cable. The guide rod is fixedly mounted on the lower bracket 21 and guides the support frame 18. The lower end of the support frame 18 is provided with a guide hole for inserting the guide rod. The second spring 19 exerts an upward elastic force on the support frame 18, causing the support frame 18 and the support wheel 17 to float. The second spring 19 is a cylindrical coil spring and a compression spring. The support wheel 17 is mounted on the support frame 18 via a wheel axle. The side connecting plate 13 is mounted on the lower bracket 21. The axis of the support wheel 17 is parallel to the axes of the cam 10, the drive wheel 16, and the guide wheel 2.

[0037] A buffer element spring is installed under the support wheel 17 to achieve flexibility during movement and to accommodate high-voltage wires of different specifications. The device has the following characteristics:

[0038] (1) Easy to produce, install and maintain, durable and highly practical;

[0039] (2) The spring flexible support effect is obvious, the speed is stable, and the slippage phenomenon is reduced;

[0040] (3) Small size, no noise, low cost and high safety.

[0041] like Figure 1 and Figure 3 As shown, the residual ice removal mechanism includes a scraper 3 for removing residual ice on the cable. The scraper 3 has a U-shaped structure and is located between the de-icing unit and the guide wheel 2. The upper open end of the scraper 3 is fixedly connected to the mounting bracket of the guide wheel 2, and the lower closed end of the scraper 3 is used to contact the cable to scrape residual ice on the cable during driving.

[0042] Since the deicing claws 5 have a too fast deicing speed and cannot ensure that the ice on the cable is removed perfectly, a residual ice removal mechanism is provided. The device has a simple structure, obvious effect, and good deicing effect.

[0043] like Figure 1 As shown, a battery 25 for supplying power to the first motor 11 and the second motor 24 is provided on the lower bracket 21 .

[0044] The utility model has been described exemplarily above in combination with the drawings. Apparently, the utility model is not limited by the above-mentioned mode in the specific implementation. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model; or the above-mentioned concept and technical scheme of the utility model are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
