Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge cable-stayed bridge de-icing, and in particular to an ice-breaking mechanism and an auxiliary device for bridge cable-stayed bridge de-icing. Background Technology
[0002] Bridges are an important part of transportation systems, and their safety in various environments is crucial. The cable surface of a cable-stayed bridge is mostly a spatial structure located directly above the bridge's roadway. In cold, rainy, or snowy weather, the cables are highly susceptible to snow and ice accumulation due to the combined effects of rain, snow, and low temperatures.
[0003] The presence of snow and ice increases the weight of the stay cables and changes their cross-sectional shape. Under these conditions, the stress state of the cables changes, and they are prone to abnormal "ice-covered vibration" under wind force, which poses a great threat to the structural safety of the bridge. In addition, the ice on the cables is prone to falling when the temperature changes, which poses a great threat to the safety of vehicles on the bridge. There have been many traffic accidents caused by falling ice from the cables on existing bridges.
[0004] Existing de-icing methods typically rely on manual labor or simple mechanical tools, which are not only inefficient but also pose significant safety risks. Manual labor requires workers to operate at heights in adverse weather conditions, resulting in high physical exertion and a risk of ice falling due to improper handling, endangering bridge traffic. Furthermore, existing tools have limited ice-breaking effectiveness and may damage the surface of the cable stays.
[0005] Therefore, there is an urgent need to propose an ice-breaking mechanism and an auxiliary device for de-icing bridge cables. Utility Model Content
[0006] Therefore, the technical problem to be solved by this utility model is that the existing tools have limited ice-breaking effect and may cause damage to the surface of the cable-stayed bridge.
[0007] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes an ice-breaking mechanism, which includes,
[0008] An ice-breaking rack includes a curved plate and ice-breaking components. The curved plate has a first side for connecting a handle and a second side for connecting the ice-breaking components, which are arranged on the second side along the travel direction of the curved plate.
[0009] In a preferred embodiment of the ice-breaking mechanism of this utility model: the ice-breaking component has a pointed ice-breaking part, and the included angle of the tip of the cross-section of the pointed ice-breaking part is between 45° and 60°.
[0010] In a preferred embodiment of the ice-breaking mechanism of this utility model: a protrusion is provided on the end of the handle away from the curved plate.
[0011] The beneficial effects of this invention are as follows: The ice-breaking frame includes a curved plate and ice-breaking components, which are arranged along the travel direction of the curved plate. This design allows the ice-breaking components to effectively penetrate the ice and snow on the surface of the cable-stayed bridge and break the ice layer by moving the curved plate, thereby achieving a highly efficient de-icing effect. Furthermore, the ice-breaking components have a pointed ice-breaking section with a pointed angle between 45° and 60° on its cross-section. This angle design effectively breaks the ice layer while minimizing damage to the cable-stayed bridge, and it can withstand greater impact forces without easily becoming damaged.
[0012] Therefore, the technical problem this invention aims to solve is that existing de-icing methods typically rely on manual operation or simple mechanical tools. These methods are not only inefficient but also pose significant safety risks. Manual operation requires workers to perform high-altitude work in adverse weather conditions, which is not only physically demanding but also prone to causing ice to fall due to improper operation, endangering bridge traffic.

[0016] A connecting rod is attached to which the remote-controlled aircraft is mounted, and the connecting rod is connected to the first housing.
[0017] In a preferred embodiment of the bridge cable de-icing auxiliary device of this utility model: the protective sleeve includes a first end and a second end disposed opposite to the first end, and the bridge cable passes through the first end and the second end.
[0018] In a preferred embodiment of the bridge cable de-icing auxiliary device of this utility model: the first end is trumpet-shaped, the narrower part of the first end faces away from the second end, and the second end is elastic.

[0023] The beneficial effects of this utility model are as follows: This utility model uses a remote-controlled aircraft to drive the protective sleeve and de-icing structure forward along the direction of the cable-stayed bridge to clear ice and snow, eliminating the need for manual climbing of the bridge or the use of large equipment, thus reducing the difficulty and risk of operation; the initial ice breaking at the first end of the protective sleeve and the further de-icing by the de-icing component work together to effectively improve the efficiency of clearing ice and snow; and the support rod is equipped with a telescopic part, which allows the distance between the support plate and the fixed plate to be adjusted according to the different diameters of the cable-stayed bridge by pressing the elastic button and moving the support rod, so that the device can meet the needs of commonly used diameter cable-stayed bridges, enhancing the versatility and applicability of the device.

[0032] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention.

[0033] Reference Figure 1 and Figure 2 This embodiment provides an ice-breaking mechanism, including an ice-breaking frame 1. The ice-breaking frame 1 includes a curved plate 11 and a plurality of ice-breaking components 12. The curved plate 11 has a first surface 111 for connecting a handle 113 and a second surface 112 for connecting the ice-breaking components 12. The ice-breaking components 12 are arranged on the second surface 112 along the traveling direction of the curved plate 11. The operator can control the movement of the curved plate 11 through the handle 113, thereby controlling the ice-breaking components 12 to insert into the ice and snow on the surface of the object to be broken and move to break the ice. In some embodiments, the curved plate 11 has a built-in heating mechanism. The heating mechanism uses a heating resistance wire, one end of which is connected to a power source. The power source is a battery, which is fixedly installed above the curved plate 11. The heating mechanism can transfer heat to the ice-breaking components 12 through the curved plate 11, assisting the ice-breaking components 12 in breaking the ice and thus improving the ice-breaking efficiency.
[0034] Reference Figure 2 and Figure 3In one embodiment provided in this application: three icebreakers 12 are provided. The icebreakers 12 are triangular prisms and have a pointed icebreaker part 121. The included angle of the tip of the cross-section of the pointed icebreaker part 121 is between 45° and 60°. An angle of 45° to 60° can effectively break the ice layer while causing less damage to the cable. In addition, the tip of this angle can withstand a large impact force during the icebreaking process and is not easily damaged. Furthermore, this angle is suitable for environments with ice thickness between 1 cm and 5 cm, which is a common ice thickness on bridge cable stays.
[0035] Reference Figure 2 In one embodiment provided in this application: a protrusion 113a is provided on the end of the handle 113 away from the curved plate 11, so the protrusion 113a makes it easier for the operator to control the mechanism.
[0036] Reference Figure 1 This embodiment provides a bridge cable-stayed bridge de-icing auxiliary device, including any of the ice-breaking mechanisms described above, and also includes a protective sleeve 2, which can protect the de-icing mechanism. The sleeve includes a first housing 21 connected to a handle 113, and a second housing 22 hinged to the first housing 21. The first housing 21 and the second housing 22 are arranged symmetrically in the upper and lower positions. A locking part 23 is provided between the first housing 21 and the second housing 22. The first housing 21 and the second housing 22 are fixed together by the locking part 23. When the locking part 23 is opened, the first housing 21 and the second housing 22 can be opened.
[0037] The device also includes an installation part 3, which includes a fixing rod 31 fixedly installed on the second housing 22, and a fixing plate 32 set on the fixing rod 31. The fixing plate 32 is used to cooperate with the curved plate 11, and is distributed vertically to fit on the bridge cable stay; a connecting rod 4, on which the remote control aircraft is installed. The connecting rod 4 is fixedly connected to the first housing 21. The connecting rod 4 is located directly above the fixing sleeve. The connecting rod 4 can be connected to the remote control aircraft. The remote control aircraft is a multi-rotor drone, which can achieve precise flight and object delivery through remote control or programming control.
[0038] Reference Figure 1 In one embodiment provided in this application: the protective sleeve 2 includes a first end 24 and a second end 25 disposed opposite to the first end 24, through which the bridge stay cable passes.
[0039] Reference Figure 1 In some embodiments: the first end 24 is trumpet-shaped, with the narrower part of the first end 24 facing away from the second end 25, and the second end 25 is made of rubber; the trumpet-shaped blade is used for the initial ice breaking of the device, which can remove some of the ice and snow on the surface of the bridge cable stays, and can also protect the ice breaking mechanism.
[0040] Specifically, when using this device, the protective sleeve 2 is in the open state, so that the second surface 112 of the curved plate 11 is in contact with the ice and snow on the bridge cable. The de-icing component can break the ice and snow and allow the bridge cable to pass through the first end 24 and the second end 25 of the first housing 21. Then the second housing 22 is closed with the first housing 21, and the locking part 23 is used to fix the first housing 21 and the second housing 22. The connecting rod 4 is installed on the remote control drone. The staff controls the remote control drone to move diagonally upward along the bridge cable. During this process, the ice-breaking component 12 continuously breaks and clears the ice and snow on the bridge cable. The first end 2411 can play a preliminary ice-breaking role.
[0041] Reference Figure 6 In one embodiment provided in this application: both the fixed plate 32 and the curved plate 11 are arc-shaped columns. The openings of the fixed plate 32 and the curved plate 11 are adjacent, and a channel 321 is formed between the fixed plate 32 and the curved plate 11. The bridge stay cable passes through the channel 321. When installing this device, the bridge stay cable passes through the channel 321 between the curved plate 11 and the fixed plate 32. The curved plate 11 and the support plate can further confine the bridge stay cable within the channel 321, thereby improving the de-icing accuracy and working efficiency of this device.
[0042] Reference Figure 1 and Figures 4-6 In one embodiment provided in this application: a collar 211 is provided on the side of the first housing 21 away from the second housing 22, the number of collars 211 corresponds to the number of handles 113, the handles 113 are movably inserted into the collars 211, the collars 211 are provided with a snap-fit part 211a, and the handles 113 are provided with a telescopic part 113b that is connected to the collars 211 and can fix the position of the support rod.
[0043] Reference Figure 5 and Figure 6 In some embodiments, multiple sets of telescopic parts 113b are provided and arranged on the handle 113. The multiple telescopic parts 113b are arranged in a straight line, and the central axis of the handle 113 is parallel to the straight line in which the multiple telescopic parts 113b are arranged. The telescopic parts 113b are telescopic buttons, and the locking part 211a is a socket opened on the collar 211 and adapted to the telescopic button. The telescopic button can be locked into the socket.
[0044] Specifically, depending on the diameter of the bridge stay cable in actual application, the distance between the curved plate 11 and the fixed plate 32 is adjusted by adjusting the position of the two handles 113. The diameter of the stay cable is smaller than that of the installation part 3 and the de-icing part, and the distance between the curved plate 11 and the fixed plate 32 meets the diameter of commonly used bridge stay cables. The adjustment process is as follows: press the elastic buttons on the two collars 211 at the same time, and then move the two handles 113 up and down at the same time as needed, so that the elastic buttons at the corresponding positions pop into the corresponding sockets.
[0045] Reference Figure 4 In one embodiment provided in this application: the locking part 23 includes a first fixing block 231 fixedly connected to the first housing 21 and a second fixing block 232 fixedly connected to the second housing 22. Bolts 233 are inserted into the first fixing block 231 and the second fixing block 232. A nut 234 is threaded onto the side of the bolt 233 away from the nut. When the locking part 23 is used to fix the first housing 21 and the second housing 22, the bolt 233 is inserted into the first fixing block 231 and the second fixing block 232, and then the nut 234 is tightened on the bolt 233. The first fixing block 231 and the second fixing block 232 are clamped by the nut 234 and the nut of the bolt 233, so that the first housing 21 and the second housing 22 can be closed and fixed into a whole; conversely, the nut 234 is unscrewed and the bolt 233 is removed, so that the first housing 21 and the second housing 22 can be opened.
[0046] Reference Figure 1 and Figure 2 In some embodiments: the use of this device is further divided into two stages; in the first stage, the remote-controlled aircraft pulls the device to the highest point of the bridge cable; in the second stage, the remote-controlled aircraft releases the connecting rod 4, and the device can fall naturally under the action of gravity. The ice-breaking component 12 can then de-ice the bridge cable again. When the device slides to the bottom of the bridge cable, the rubber material of the second end 25 can buffer the protective sleeve 2 and protect the device. Through the second stage, the bridge cable can be de-iced a second time, and the device can be retrieved without relying on the remote-controlled aircraft.
[0047] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
