DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below with reference to specific diagrams.

[0022] Example: Figure 1-6 As shown, a deicing device suitable for suspension bridge cables includes a motion module 1, which is slidably connected to the suspension bridge cables 2. The slings 3 are installed on the suspension bridge cables 2 through cable clamps 4. The motion module is provided with a deicing module 5, which includes two symmetrically arranged spiral blades 6. The spiral blades 6 are made of metal material. The spiral blades 6 are provided with an electric heating wire heating mechanism for cutting ice spikes on the suspension bridge cables 2. An ice collecting module 7 is provided on the lower side of the deicing module 5, and the ice collecting module 7 is used to collect the cut ice spikes.

[0023] Furthermore, the motion module 1 includes two parallel main beams 8, the main beams 8 are configured to be retractable, and the main beams 8 include two symmetrical main beam units, which are connected by a telescopic rod to achieve the telescopic function of the main beam 8. The two main beams 8 are connected by four rods, and the upper ends of the two main beams 8 are provided with a power supply module 9 and four flying fans 10, which are arranged symmetrically in pairs and are used to drive the entire device to take off, land, and hover in the air.

[0024] Among them, the power supply module 9 is arranged at the top of the device and fixedly connected to the motion module 1. The power supply module 9 is a high-energy battery pack, which is connected to the electric heating wire heating mechanism, the motion module 1, etc. in the device through lines to provide continuous power supply to ensure heating, the flight fan 10 and the rolling of the wheels in the device.

[0025] Furthermore, the lower sides of the two main beams 8 are connected to the four fixed wheels 12 of the fixed wheel group through four fixed wheel connecting rods 11, and the four fixed wheels 12 are slidably connected to the top of the suspension bridge cable 2. Fixed columns 13 are provided on the lower sides of both ends of the two main beams 8. The two fixed columns 13 at the same end are connected through a side beam 14. The side beam 14 at the same end is connected to the two special-shaped wheels 16 of the special-shaped wheel group through two special-shaped wheel connecting rods 15. The special-shaped wheels 16 at both ends are respectively slidably connected to the two side ends of the suspension bridge cable 2. The spiral blade 6 is placed between the two special-shaped wheels 16. The side beam 14 is connected to the spiral blade 6 through a blade connecting rod 17. The blade connecting rod 17 is placed in the middle of the two special-shaped wheel connecting rods 15. The spiral blade 6 can make circular motion around the central axis of the connection through a motor. A slidable support sleeve 29 is provided on each blade connecting rod 17, and the top of the support sleeve 29 is connected to the bottom of the power supply module 9 through the support column 19. The blade connecting rod 17 and the special-shaped wheel connecting rods 15 on both sides are hingedly connected through connecting rods 30, and both ends of the connecting rod 30 are provided with inclined notches 32, and the inclined notches 32 at both ends are located on different sides.

[0026] Furthermore, the blade connecting rod 17 is connected to the first sleeve 21 through the first spring 20, and the first sleeve 21 is movably connected to the side beam 14. The special-shaped wheel connecting rod 15 is connected to the second sleeve 23 through the second spring 22, and the second sleeve 23 is movably connected to the side beam 14 through the slide 24. The slide 24 has a small length, so that the second sleeve 23 has a certain lateral movement space. The first spring 20 and the second spring 22 are both provided with an electrically controlled retractable support rod inside, one end of the retractable support rod is connected to the blade connecting rod 17 or the special-shaped wheel connecting rod 15, and the other end can be freely extended into the first sleeve 21 or the second sleeve 23. The outer ends of the first sleeve 21 and the second sleeve 23 are both provided with a driving fan 18, and the driving fan 18 is electrically connected to the power supply module 9.

[0027] Furthermore, the ice collecting module 7 includes two symmetrically arranged ice collecting ice bins 25 , and the bottoms of the two blade connecting rods 17 are respectively connected to the outer sides of the two ice collecting ice bins 25 through two connecting columns 26 .

[0028] Furthermore, a three-layer ice crushing mechanism is arranged inside the refrigerator 25, and the ice crushing mechanism includes several rotating shafts, on which ice crushing blades 31 are fixed. The rotating shafts become denser from top to bottom to ensure the ice crushing effect. A rotating fan 27 is arranged at both ends of each rotating shaft. The rotating fan 27 is installed on the outside of the refrigerator 25 and is connected to the rotating shaft inside the refrigerator 25. The rotating fan 27 is driven to rotate by the strong wind force at high altitude.

[0029] Furthermore, a plurality of smaller ice discharge ports 28 are provided at the bottom of the ice collecting refrigerator 25. After the spiral blade 6 cuts the ice shards, the ice shards will fall into the ice collecting refrigerator 25, effectively avoiding the potential safety hazard caused by the ice shards falling during the de-icing process. When the ice shards fall into the ice collecting refrigerator 25, due to the wind force, the rotating fan 27 drives the rotating shaft and the ice crushing blade 31 to rotate. Under the repeated cutting action of the ice crushing blade 31, the ice shards are cut into ice slag and discharged through the ice discharge port 28 at the bottom of the ice collecting refrigerator 25.

[0030] When the deicing device is used, when the device moves at the suspension cable 3 of the suspension bridge, the motion module 1 can control the position of the spiral blade 6 through the blade connecting rod 17, so as to avoid the spiral blade 6 from colliding with the suspension cable 3. The electric heating wire heating mechanism can keep the metal spiral blade 6 at a certain temperature at all times, and the rotation of the spiral blade 6 and the electric heating wire heating mechanism are both powered by the power supply module 9; when the spiral blade 6 contacts the ice ridge, the ice ridge can be quickly cut by the temperature of the blade during heating and the high-speed rotation of the spiral blade 6 itself.

[0031] Specifically, when the device moves on the suspension bridge cable 2, assuming that when the device moves from one end of the suspension bridge cable 2 to the other end, the shaped wheel group on the first side first passes through the cable clamp 4, then when the device returns, the shaped wheel group on the second side first passes through the cable clamp 4. Taking the case where the shaped wheel group on the first side first passes through the cable clamp 4 as an example, since the cable clamp 4 has an additional protrusion compared to the suspension bridge cable 2, after the shaped wheel group on the first side contacts the cable clamp 4, the second spring 22 on the first side is compressed, and the shaped wheel connecting rod 15 on the first side moves outward in the horizontal direction. Since the connecting rod 30 on the first side is hinged and has an inclined notch 32, the outward movement of the shaped wheel connecting rod 15 on the first side will drive the connecting rod 30 on the first side to move outward, and the connecting rod 30 on the first side drives the blade connecting rod 17 to move outward. Since the connecting rod 30 on the second side hinged to the other side of the blade connecting rod 17 has an inclined notch 32, the connecting rod 30 on the second side will be in an inclined state when the blade connecting rod 17 moves outward. At this time, because the connecting rod 30 on the second side is inclined, the distance between the special-shaped wheel connecting rod 15 on the second side and the blade connecting rod 17 will be reduced, and the second sleeve 23 on the second side can move slightly toward the blade connecting rod 17 through the slide groove 24 on the second side, thereby not affecting the special-shaped wheel group on the second side to continue to slide on the suspension bridge cable 2, until the special-shaped wheel group on the second side also collides with the cable clamp 4, and then it will produce horizontal outward movement due to the protrusion of the cable clamp 4.

[0032] When the special-shaped wheel set on the first side first leaves the cable clamp 4, the second spring 22 on the first side will rebound, so that the special-shaped wheel set on the first side returns to the suspension bridge cable 2. At this time, due to the obstruction of the connecting rod 30 on the second side, the blade connecting rod 17 will maintain its original state; when the special-shaped wheel set on the second side also leaves the cable clamp 4, the second spring 22 on the second side will rebound, so that the special-shaped wheel set on the second side returns to the suspension bridge cable 2. At this time, the constraint of the connecting rod 30 on the blade connecting rod 17 on the second side disappears. Under the rebound force of the first spring 20, the blade connecting rod 17 will rebound, and the spiral blade 6 returns to its original position. At this point, the device passes through the cable clamp 4 and successfully avoids the sling 3. When the device moves to one end of the suspension bridge and moves in the opposite direction, since the device is a symmetrical structure, the process of passing through the sling 3 is similar to the above.

[0033] When the flying fan 10 drives the device to take off and hover on the suspension bridge cable 2, the flying fan 10 is first used to adjust the position so that the fixed wheel group stands on the suspension bridge cable 2, and then the retractable support rod inside the first spring 20 and the second spring 22 is controlled to maintain the same length as the spring, and the fan 18 is driven to rotate to move the special-shaped wheel connecting rod 15 inward (the retractable support rod can prevent the spring from being compressed during movement) until the special-shaped wheel 16 contacts the side of the suspension bridge cable 2, completing the fixation of the device on the suspension bridge cable 2. After fixation, the flying fan 10 continues to rotate to adjust the balance of the device, and the retractable support rod returns to the contracted state.

[0034] The method for removing ice ridges by the device comprises the following steps: S1: The device is initially installed on the suspension bridge cable 2, and stable operation on the suspension bridge cable 2 is achieved through the special-shaped wheel 16 and the flying fan 10.

[0035] S2: When the device runs to the place where the ice ridge is hung, the spiral blade 6 collides with the ice ridge, and the ice ridge is cut by the temperature and high-speed rotation of the blade.

[0036] S3: After being cut, the ice shards will fall into the ice collecting ice box 25 , and the ice shards will be cut by the ice crushing mechanism in the ice collecting ice box 25 and become ice slag, which will be discharged through the ice discharge port 28 at the bottom of the ice collecting ice box 25 .

[0037] S4: Under the continuous action of S1-S3, all the ice ridges in the ice collecting ice box 25 are finally discharged in the form of ice slag, ensuring that the device can achieve long-span and uninterrupted ice ridge removal.

[0038] The method of the device passing through the suspension bridge cable comprises the following steps: S1: The device is initially installed on the suspension bridge cable 2, and stable operation on the suspension bridge cable 2 is achieved through the special-shaped wheel 16 and the flying fan 10.

[0039] S2: When the device runs to the cable clamp 4, since the cable clamp 4 has a protrusion compared to the cable, when the special-shaped wheel group on the first side passes the cable clamp 4, the second spring 22 on the first side is compressed, and the special-shaped wheel connecting rod 15 on the first side moves forward and drives the connecting rod 30 on the first side to move synchronously.

[0040] S3: Driven by the connecting rod 30 on the first side, the blade connecting rod 17 moves forward and drives the spiral blade 6 and the connecting column 26 to move forward together, so that the spiral blade 6 and the ice box collection 25 avoid the area where the sling 3 is located.

[0041] S4: When the device as a whole leaves the cable clamp 4, the shaped wheels 16 return to the suspension bridge cable 2. Under the action of the spring rebound force, the blade connecting rod 17 and the connecting column 26 move backward and return to their original positions, and bring the spiral blade 6 and the ice collector 25 back to the working position to continue removing ice spikes.

[0042] The above are only implementation modes of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention's specification and drawings, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present invention.
