Abstract
Description
Technical Field
[0001] This utility model relates to the field of anti-icing devices, and in particular to an anti-icing device for bridge piers. Background Technology
[0002] When the river thaws, ice blocks move with the water flow. To prevent ice blocks from directly hitting the bridge piers, anti-icing devices are wrapped around the outer layer of the piers. The anti-icing devices are integrally formed with the bridge piers and are fixed in position. However, the river water level fluctuates significantly with factors such as season, weather, and upstream flow, causing the height of the ice layer to change accordingly. When the height of the ice layer is lower than the lowest point of action of the fixed anti-icing device, the device completely fails and cannot perform its ice-breaking function, leaving the bridge pier unprotected. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0018] In this embodiment, as Figure 1 and Figure 2 As shown, an anti-icing device for a bridge pier includes: an impact-resistant component 2, which is adjustable up and down along the water-facing side of the bridge pier 1 to break ice layers of different heights; an adjustment component 3, which is used to adjust the position of the impact-resistant component 2; the impact-resistant component 2 includes: an ice-blocking plate 21, which is located on the water-facing side of the bridge pier 1, and ice-breaking cones 211 are evenly distributed on the water-facing side of the ice-blocking plate 21; a limiting slide rail 22, which is slidably connected to the ice-blocking plate 21, and the side of the limiting slide rail 22 away from the ice-blocking plate 21 is fixedly connected to the bridge pier 1; and a locking member 23, which is used to fix the position of the ice-blocking plate 21.
[0019] As a result, the upstream ice blocks are carried by the river toward the bridge pier 1. At this time, the ice-breaking cone 211 located on the water-facing side of the ice-blocking plate 21 comes into contact with the ice blocks to break them. Depending on the water level in different seasons, the position of the ice-blocking plate 21 on the outer wall of the two limiting slide rails 22 is changed by moving the ice-blocking plate 21 on the outer wall of the bridge pier 1, thereby adjusting the position of the ice-breaking cone 211 and adapting the ice-blocking plate 21 and the ice-breaking cone 211 to rivers of different depths.
[0020] Specifically, the ice-blocking plate 21 is machined with grooves that are compatible with the bridge pier 1. The ice-breaking cones 211 are evenly distributed along the water-facing side of the ice-blocking plate 21. The number of ice-breaking cones 211 used is not specifically limited. The limiting slide rail 22 is machined in a T-shape, and the ice-blocking plate 21 is provided with grooves that are compatible with the limiting slide rail 22.
[0021] In some embodiments, such as Figure 2 As shown, the locking component 23 includes: a countersunk hole 231, which is evenly distributed based on the limiting slide rail 22, and a magnetic block 231a is disposed in the countersunk hole 231; and a pin 232, which passes through the ice-blocking plate 21 and is connected to the countersunk hole 231, and the end of the pin 232 away from the ice-blocking plate 21 is attracted to the magnetic block 231a.
[0022] Specifically, the countersunk hole 231 is recessed into the limiting slide rail 22, the magnetic block 231a can be a neodymium iron boron magnet, and pins 232 are provided on both sides of the ice-blocking plate 21. The magnetic block 231a is used to attract the pins 232 to prevent the pins 232 from separating from the ice-blocking plate 21. It should be noted that, since the pin 232 can be embedded in the groove of the ice-blocking plate 21, the water flow is not likely to cause the pin 232 and the ice-blocking plate 21 to separate.
[0023] In some embodiments, such as Figure 3As shown, the adjustment assembly 3 includes: a mounting shell 31, which is connected to the top of the pier 1 at a preset height; a drive shaft 32, which is connected to the mounting shell 31 via a bearing, and a slide block 321 is threadedly connected to the outer circumference of the drive shaft 32; a connecting frame 33, which is fixedly connected to the outer circumference of the slide block 321, and the side of the connecting frame 33 away from the slide block 321 is connected to the anti-icing plate 21; and a driving component 34, which is used to drive the drive shaft 32 to rotate. Specifically, the top of the mounting shell 31 is designed with a cavity to wrap around the outer periphery of the first gear 342 and the second gear 343. The drive shaft 32 rotates in the mounting shell 31 through bearings. When the slide 321 moves on the drive shaft 32, it drives the connecting frame 33 to move. The connecting frame 33 and the ice-blocking plate 21 are fixedly connected and move together.
[0024] In some embodiments, such as Figure 4 As shown, the drive component 34 includes: a rotating rod 341, which is connected to the mounting housing 31 via a bearing; a first gear 342, whose center hole is connected to the rotating rod 341, and a second gear 343 meshing with the outer periphery of the first gear 342, whose center hole is connected to the drive shaft 32.
[0025] Specifically, the rotating rod 341 rotates in the mounting housing 31 via a bearing, and the first gear 342 rotates together with the rotating rod 341. The meshing between the first gear 342 and the second gear 343 drives the transmission shaft 32 to rotate.
[0026] In some embodiments, such as Figure 4 As shown, a handwheel 341a is provided at the bottom end of the rotating rod 341; Specifically, handwheel 341a is used to drive rotating rod 341 to rotate. Depending on the on-site construction conditions, handwheel 341a can also be replaced by a motor to provide power.
[0027] In some embodiments, such as Figure 2 As shown, the anti-icing plate 21 is made of stainless steel. Specifically, the anti-icing plate 21 is made of stainless steel to reduce the probability of rust. In addition, during actual production, an anti-corrosion coating needs to be applied to the surface of the anti-icing plate 21.
[0028] In some embodiments, such as Figure 2 As shown, the limiting slide rail 22 is symmetrically distributed based on the anti-icing guard plate 21; Specifically, the limit slide rail 22 is designed with two rails to make the up-and-down adjustment of the anti-icing guard plate 21 more stable.
[0029] In some embodiments, such as Figure 2As shown, the water-facing surface of the icebreaker cone 211 is machined into a blade shape.
[0030] Specifically, the icebreaker 211 is designed with a blade-like shape, using sharp edges to enhance the breaking effect on the ice surface. In addition, the water-facing side of the icebreaker 211 can also be processed into a cone shape or other pointed shapes.
[0031] The working principle of this application is illustrated below with a preferred embodiment: When the position of the ice-blocking plate 21 needs to be adjusted according to the river's liquid level, firstly, the pin 232 is pulled out of the ice-blocking plate 21, separating the pin 232 from the magnetic block 231a in the countersunk hole 231. Then, the handwheel 341a is manually turned, which drives the rotating rod 341 and the first gear 342 to rotate together. Under the action of the first gear 342, the second gear 343 is rotated, and the transmission shaft 32 located in the center hole of the second gear 343 rotates. The rotation of the transmission shaft 32 drives the slide 321 to move, and the slide 321 drives the connecting frame 33 and the ice-blocking plate 21 to move together. At the same time, the ice-blocking plate 21 moves along the outer periphery of the limiting slide rail 22 to change its position on the outer wall of the pier 1. After the height of the ice-blocking plate 21 is adjusted, the pin 232 is reinserted into the countersunk hole 231 and connected to the magnetic block 231a, thereby locking the position of the ice-blocking plate 21 and the limiting slide rail 22. As the ice begins to melt, the upstream ice blocks are carried by the river toward the bridge pier 1. At this time, the ice-breaking cone 211 located on the water-facing side of the ice-blocking plate 21 comes into contact with the ice blocks to break them.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
