Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge deicing, and more specifically, to a road and bridge deicing device. Background Art

[0002] In the existing technology, road and bridge deicing devices are important equipment for maintaining traffic order in winter. The main function of these devices is to remove ice and snow on roads and bridges during the winter icing period to ensure driving safety. However, the existing deicing devices have certain limitations during use. In particular, when deicing, it is necessary not only to break the ice, but also to melt the ice close to the ground, which requires the deicing device to provide sufficient heat and appropriate airflow speed.

[0003] Existing de-icing devices usually melt ice and snow by blowing hot air. This method uses the heat of the hot air to melt the ice and snow by blowing hot air onto the ice surface. However, the existing equipment cannot adjust the flow rate at the nozzle, which limits the adaptability of the equipment. Due to different road and bridge conditions, as well as different thicknesses of ice and snow, different air flow speeds are required to achieve the best de-icing effect. If the air flow speed is too fast, the ice and snow may be blown away instead of melted, resulting in poor de-icing effect; if the air flow speed is too slow, it may cause uneven heat distribution, resulting in low de-icing efficiency.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a road and bridge deicing device having the following features:

[0017] Beneficial effects:

[0018] 1. The design of the adjustment mechanism solves the problem that the existing road and bridge deicing device cannot adjust the hot air flow rate at the nozzle. By installing telescopic discs on the fixed tube and the external tube respectively, and connecting the two telescopic discs through the reverse thread of the bidirectional lead screw, the synchronous reverse movement of the telescopic disc is realized. A fixed ring is installed in the fixed tube and the external tube, and the two ends of multiple elastic sheets are connected to the two fixed rings respectively. Multiple guide sheets are installed on the elastic sheets respectively. By rotating the internal gear, the bidirectional lead screw is driven to rotate, thereby driving the two telescopic discs to move in the opposite direction. When the telescopic disc is stretched, the elastic sheet is pulled, which increases the flow space of the hot air and reduces the flow resistance, thereby increasing the flow rate of the hot air; when the telescopic disc is close, the elastic sheets are close to each other, which increases the flow resistance and reduces the flow rate of the hot air. This design realizes the adjustable hot air flow rate by adjusting the spacing of the elastic sheets, and improves the adaptability and practicality of the deicing device.

[0019] 2. The design of the blowing mechanism ensures uniform blowing and effective coverage of hot air. By installing a baffle on the mobile frame and a transverse pipe on the baffle, the transverse pipe is connected to multiple nozzles to achieve dispersed blowing of hot air. The transverse pipe is also connected to a vertical pipe, which is connected to the fixed pipe to ensure that hot air flows from the external pipe into the fixed pipe and finally sprays out through the nozzle. Multiple nozzles are connected to the transverse pipes respectively to achieve uniform distribution of hot air. This design fully considers the unevenness of the road and bridge surface, and improves the coverage and deicing effect of hot air by dispersed blowing.

[0020] 3. The design of the rotating mechanism realizes efficient de-icing of the ice layer on the surface of the road and bridge. When the transmission shaft rotates, the follower block can rotate along the shaft. Under the action of centrifugal force, the de-icing block will hit the ice surface to break the ice layer. Since the follower block is connected to the shaft in a rotating manner and the de-icing block is flexibly connected to the transmission shaft, the de-icing force of the de-icing block can be adjusted by controlling the rotation speed of the transmission shaft to avoid damage to the road surface. This design uses the principle of centrifugal force to achieve efficient de-icing of the ice layer. At the same time, it protects the surface of the road and bridge through a flexible connection and extends the service life of the road and bridge. The drive box is connected to the external drive equipment, which is convenient for integration with mobile equipment such as vehicles, and improves the mobility and flexibility of the de-icing device.

The air blowing mechanism is cooperatively connected to the fixed pipe 2 and the mobile frame 1, the external pipe 3 is connected to the external air intake mechanism, the bellows 4 are respectively connected to the external pipe 3 and the fixed pipe 2, a plurality of elastic sheets 6 are provided, and the two ends of the plurality of elastic sheets 6 are respectively connected to two fixed rings 5, the two fixed rings 5 ​​are respectively installed in the fixed pipe 2 and the external pipe 3, a plurality of guide sheets 7 are provided, and the plurality of guide sheets 7 are respectively installed on the elastic sheet 6, the fixed pipe 2 and the external pipe 3 are respectively installed with telescopic disks 8, bidirectional lead screws 9 They are respectively connected to the two telescopic disks 8 with reverse threads, and the rotating mechanism is connected to the moving frame 1. The two ends of the multiple bidirectional lead screws 9 are respectively meshed with internal gears 10, and a lever 11 is provided between the two internal gears 10. The two ends of the bidirectional lead screws 9 are respectively provided with limit rings 12, and the internal gear 10 is fitted on the limit ring 12. The two ends of the bidirectional lead screws 9 are respectively threaded with nuts 13, and the nuts 13 abut against the internal gear 10. A plurality of tension springs 14 are provided between the two fixed rings 5, and the plurality of tension springs 14 are respectively equidistantly arranged.

[0031] In this embodiment, when de-icing is completed by the de-icing block 22 and air blowing and drying is required, hot air is introduced through external equipment, and then sprayed onto the ground through the transverse pipe 15 and multiple nozzles 16, thereby melting the ice on the ground. When the flow rate needs to be adjusted to adapt to different ice surfaces, by rotating the internal gear 10, since the internal gear 10 is engaged with the two-way lead screw 9, it can drive the rotation of multiple two-way lead screws 9. Since the two telescopic disks 8 are respectively threadedly connected to the two-way lead screw 9 in reverse, the two telescopic disks 8 can be driven to move in reverse, and the expansion amount can be compensated by the bellows 4. When the two telescopic disks 8 are stretched, multiple elastic sheets 6 are also pulled, thereby increasing the flow space and reducing the flow resistance, thereby adjusting the inflow flow rate. When the flow rate needs to be reduced, the resistance can be increased by bringing the multiple elastic sheets 6 close to each other, thereby reducing the flow rate, thereby completing the flow rate adjustment.

Since the follower blocks 21 are rotatably connected to the rotating shaft 20, the de-icing blocks 22 and the drive shaft 19 are flexibly connected. Controlling the rotation speed of the drive shaft 19 can control the de-icing force of the de-icing blocks 22, thereby avoiding damage to the road and completing the de-icing process.
