Description

Technical Field

[0001] This utility model belongs to the field of power transmission line de-icing technology, and specifically relates to a line de-icing device for power distribution line operations. Background Technology

[0002] Power distribution lines refer to the lines that transmit power from step-down substations to distribution transformers or from distribution substations to power-consuming units. Currently, power distribution lines are prone to icing on the outside, which affects their operation and requires regular de-icing by staff.

[0003] The utility model patent with publication number CN220382732U proposes a de-icing device for power transmission lines. Although it improves practicality by adding a collection box that is easy to disassemble and assemble to collect ice blocks, preventing ice blocks from falling and injuring crops and livestock, its solution still has the following problems: When the line is long or heavily iced, the amount of ice blocks that can be loaded inside the collection box is limited, and the device and collection box need to be repeatedly removed to clean the ice blocks inside, which is inconvenient to use. If the size of the collection box is increased, the weight of the device will increase, increasing the load on the line and posing a safety risk. There may be ice blocks with high hardness on the line, and a single cleaning may not be enough to remove them completely. Utility Model Content

[0004] To address the existing technical problems, this utility model proposes a line de-icing device for power distribution line operations, which solves the problems of limited loading capacity and incomplete ice removal in current line de-icing devices.

[0005] The purpose of this utility model and the technical problem it solves are achieved by the following technical solution. According to this utility model, a line de-icing device for power distribution line operations includes a de-icing refrigerator with an open top. An de-icing mechanism and a traveling mechanism are provided on the inner wall of the top of the de-icing refrigerator. An ice storage compartment is provided at the bottom of the de-icing refrigerator. Guide plates are symmetrically arranged at the upper end of the ice storage compartment. The guide plates are inclined and used to guide the ice blocks. An ice-crushing roller is rotatably provided at the discharge port of the guide plate, and the ice-crushing roller has several crushing blades. An electric heating plate is fixedly connected to the inner wall around the ice storage compartment, and the bottom surface of the ice storage compartment is connected to several drainage holes.

[0006] Furthermore, the de-icing mechanism includes a striking mechanism and an ice-scraping mechanism. The striking mechanism includes a support rod fixed to the front end of the de-icing refrigerator, and a striking rod driven by a rotary motor and used to strike the circuit on the support rod. The ice-scraping mechanism includes a first electric push rod symmetrically arranged on the inner walls of both sides of the de-icing refrigerator. The extended end of the first electric push rod is fixed with an arc-shaped ice-breaking shell. After the two ice-breaking shells are joined together, they can form an ice-breaking sleeve that completely covers the circuit.

[0007] Furthermore, the ice-breaking shell is inserted into the extension end of the first electric actuator via a connecting sleeve, and the connecting sleeve is locked to the first electric actuator through the engagement of its top screw hole and bolt.

[0008] Furthermore, the walking mechanism includes a front walking mechanism and a rear walking mechanism. The front walking mechanism and the rear walking mechanism each include a second electric push rod and a third electric push rod symmetrically arranged on the inner walls of both sides of the refrigerator. The extension ends of the second electric push rod and the third electric push rod are respectively provided with a front wheel and a rear wheel driven by a motor. The two front wheels and the rear wheel are respectively engaged with the outer edge of the circuit through the wheel grooves on them.

[0009] Furthermore, the front wheels, rear wheels, and motor are detachably connected.

[0010] Furthermore, an ice-receiving tray is provided at the front of the refrigerator.

[0011] Furthermore, a power bank is provided on the refrigerator.

[0012] Furthermore, the electric heating plate is a waterproof type.

[0013] In summary, this utility model has the following advantages:

[0014] 1. In addition to the ice crushing roller and heating plate inside the refrigerator, which are connected to the outside through the drain hole, the ice can be crushed and melted while collecting ice. After that, the water droplets from the melted ice are discharged through the drain hole. This not only avoids the problem of ice falling and injuring crops or people and livestock, but also allows for continuous collection of ice. It is suitable for working conditions with long lines or heavy ice accumulation. There is no need to clean the ice storage compartment repeatedly, which improves work efficiency and facilitates de-icing.

[0015] 2. For ice-covered lines with high hardness, the striking mechanism can break and loosen the ice on the line, and the ice scraping mechanism can remove the ice after completely wrapping the line, which is conducive to cleaning up the ice with high hardness. At the same time, multiple de-icing can ensure that the line is thoroughly de-iced and ensure the safety of the line's power supply.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0021] Please see Figure 1 A line de-icing device for power distribution line operation includes a de-icing refrigerator 1 with an open top and a mobile power supply 15 disposed on the outer side of the de-icing refrigerator 1. The inner wall of the top of the de-icing refrigerator 1 is provided with a de-icing mechanism and a walking mechanism.

[0022] The de-icing mechanism includes a striking mechanism and an ice-scraping mechanism. The striking mechanism includes a support rod 5 fixed to the front end of the de-icing refrigerator 1 (i.e., the forward end of the de-icing refrigerator 1). The support rod 5 is equipped with a striking rod 3 driven by a rotary motor 4 and used to strike the circuit. The length of the striking rod 3 must be greater than the straight-line distance from the circuit to the rotation point of the striking rod 3. When the striking rod 3 reciprocates, it can strike the circuit to break or loosen the ice covering the circuit surface. The ice-scraping mechanism includes first electric push rods 8 symmetrically arranged on the inner walls of both sides of the de-icing refrigerator 1. The extended end of the first electric push rod 8 is fixed with an arc-shaped ice-breaking shell 9. The two ice-breaking shells 9 After docking, an ice-breaking sleeve can be formed to completely enclose the circuit. When the two first electric push rods 8 extend in opposite directions, the two ice-breaking shells 9 clamp the circuit. When moving, the ice on the surface of the circuit can be scraped off. The front end of the ice-breaking shell 9 (i.e. the end near the forward direction of the refrigerator 1) can be chamfered to facilitate the scraping off of ice. Furthermore, the ice-breaking shell 9 can be inserted into the extended end of the first electric push rod 8 through the connecting sleeve 19. The connecting sleeve 19 is locked with the first electric push rod 8 through the cooperation of its top screw hole and bolt 18. Ice-breaking shells 9 of different sizes can be replaced as needed to adapt to circuits of different diameters.

[0023] The walking mechanism includes a front walking mechanism and a rear walking mechanism. The front walking mechanism and the rear walking mechanism each include a second electric push rod 6 and a third electric push rod 10 symmetrically arranged on the inner walls of both sides of the refrigerator 1. The extended ends of the second electric push rod 6 and the third electric push rod 10 are respectively provided with a front wheel 7 and a rear wheel 11 driven by a motor. The wheel surfaces of the front wheel 7 and the rear wheel 11 are provided with wheel grooves that fit with the line. The two front wheels 7 and the rear wheel 11 are respectively clamped on the outer edge of the line through the wheel grooves so that the refrigerator 1 is completely attached to the line. The front wheels 7 and the rear wheel 11 are detachably connected to the motor. For example, the walking wheels can be fixed to the drive shaft of the motor by bolts. The front wheels 7 and the rear wheels 11 with different sizes of wheel grooves can be replaced according to the size of the line to adapt to the use of lines with different diameters.

[0024] The striking mechanism needs to be located at the front end of the refrigerator 1 to pre-de-ice and remove larger ice blocks, ensuring the stable operation of the refrigerator 1 on the line. In addition, the front walking mechanism, the rear walking mechanism, and the ice scraping device are set at the same height, and the front-to-back order of the three can be determined according to the requirements. In this embodiment, the ice scraping mechanism is set in the middle of the two walking mechanisms, which has better driving stability and can avoid the problem of concentrated load on a certain part of the line causing damage to the line.

[0025] Please see Figure 2 , Figure 3 In addition to the ice storage compartment at the bottom of the refrigerator 1, the upper end of the ice storage compartment is symmetrically equipped with guide plates 12. The guide plates 12 are inclined and outward V-shaped, which can be used to guide ice blocks into the ice storage compartment. The ice crushing roller 13 driven by a motor is rotated at the discharge port of the guide plate 12. The ice crushing roller 13 is equipped with several crushing blades 14. The ice blocks entering the ice storage compartment through the guide plate 12 are crushed into small particles, reducing the melting time. Waterproof electric heating plates 16 are fixed to the inner walls around the ice storage compartment, and the bottom surface of the ice storage compartment is connected to several drainage holes 17. The electric heating plates 16 melt ice and water, and the water flows out through the drainage holes 17. The diameter of the drainage holes 17 is small. At the same time, a metal filter screen can be installed on the bottom surface of the ice storage compartment to further prevent small ice fragments from passing through the drainage holes 17 and to prevent them from damaging crops or people and animals below.

[0026] The front end of the refrigerator 1 is provided with an ice-receiving tray 2, which protrudes from the refrigerator 1. When the striking mechanism strikes the circuit, it will shake off some ice blocks on the circuit at the front end of the refrigerator 1. The ice-receiving tray 2 catches these ice blocks and prevents them from falling out of the refrigerator 1.

[0027] The rotary motor 4, the first electric push rod 8, the second electric push rod 6, the third electric push rod 10, the motors driving the front wheel 7 and the rear wheel 11, the drive motor of the ice crushing roller 13, and the electric heating plate 16 are electrically connected to the mobile power supply 15, thereby controlling the operation of each electrical component. At the same time, a remote control module can be set inside the device and connected to a mobile terminal, thereby facilitating the operation of the device.

[0028] Furthermore, a sensor for monitoring the ice filling amount can be installed inside the ice storage compartment. The sensor is located at the maximum filling amount scale line. When the sensor alarms, the operation of the de-icing refrigerator 1 is paused, and the ice is melted for a period of time by the electric heating plate 16 before the de-icing operation is restarted.

[0029] Work process:

[0030] First, place the refrigerator 1 below the power line, with the wheel grooves of the front wheel 7 and rear wheel 11, as well as the ice-breaking shell 9, at the same height as the power line. Then, extend the first electric push rod 8, the second electric push rod 6, and the third electric push rod 11, so that the two front wheels 7, the rear wheel 11, and the ice-breaking shell 9 clamp the power line, and the refrigerator 1 is connected to the power line as a whole. It should be noted that the ice-breaking shell 9 does not need to completely clamp the power line; there should be a certain gap between it and the outer wall of the power line to avoid damaging the power line. Then, start the rotary motor 4 to drive the striking rod 3 to repeatedly strike the power line, shaking off and loosening some of the ice. At the same time, the ice-breaking sleeve composed of the ice-breaking shell 9 scrapes off the ice on the surface of the power line again. The fallen ice blocks fall into the ice storage chamber through the ice receiving bucket 2 and the guide plate 12. At the same time, the ice crushing roller 13 drives the crushing blades 14 to rotate and crush the ice blocks that have entered the ice storage chamber. After the ice blocks are turned into small particles, they are heated and melted into water by the electric heating plate 16 inside the ice storage chamber, and then discharged through the bottom drain hole 17.

[0031] The above description is merely a preferred embodiment of this utility model. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the scope of the technical solution of this utility model.
