Description

Technical Field

[0001] This utility model relates to the field of river ice treatment technology, specifically to a device for monitoring and breaking ice on river surfaces. Background Technology

[0002] In cold regions, the formation and accumulation of ice floes on rivers during winter pose a significant threat to flood control, navigation, and the stability of water conservancy facilities. As ice floes move with the water flow, they can easily form ice jams or ice dams in narrow downstream river sections, bridge piers, and other areas, leading to sudden rises in water levels, river blockages, and even ice jam floods.

[0003] Traditional methods for dealing with ice jams mainly rely on manual patrols and monitoring, as well as passive ice breaking. Existing ice monitoring equipment (such as fixed water level sensors and shore cameras) is mostly deployed independently, making it difficult to dynamically adapt to water level fluctuations. Especially during the winter period when rivers freeze and thaw, water levels change frequently, leading to fixed sensor installation heights and making it easy for monitoring blind spots or equipment to be damaged by water immersion. At the same time, most existing ice breaking methods involve blasting the ice surface, but this method is often used after the ice has completely frozen, and it cannot deal with the thinner ice surface in the early stages of freezing. If the thinner ice surface is not contained, it will gradually thicken, increasing the difficulty of subsequent treatment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a river ice monitoring and ice-breaking device, which solves the problems that monitoring equipment is difficult to adapt to water level changes and lacks countermeasures in the early stages of ice formation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a river ice monitoring and ice-breaking device, comprising a top plate, a lifting plate and a lifting mechanism, wherein a mounting base is fixedly connected to the upper surface of the top plate, and the mounting base is fixedly installed below the bridge deck;

[0006] The lifting mechanism is located on the lower surface of the top plate and connected to the lifting plate to control the height of the lifting plate;

[0007] The lifting plate has rotating rods on both sides, and a connecting chain is fixedly connected to the bottom of the rotating rod.

The driving mechanism is connected to the rotating rod to drive the rotating rod to rotate. A mounting hole is provided on one side of the lifting plate to install a monitoring device.

[0008] Optionally, the lifting mechanism includes a slider and a connecting rod. The slider is slidably disposed on the lower surface of the top plate. The connecting rod is rotatably connected to the bottom of the slider via a rotating shaft. The other end of the connecting rod is rotatably connected to the upper surface of the lifting plate via a rotating shaft. The slider and the connecting rod are grouped in pairs, and the middle of the two connecting rods are connected by a rotating shaft.

[0009] Optionally, a drive motor is fixedly connected to the lower surface of the top plate, and a rotating shaft is fixedly connected to the output end of the drive motor. The rotating shaft passes through the slider, and the surface of the rotating shaft is provided with threads in opposite directions. The two sliders are respectively adapted to the threads on both sides.

[0010] Optionally, the drive mechanism includes a dual-axis motor, a reciprocating screw, and a drive wheel. The dual-axis motor is fixedly connected to the upper surface of the lifting plate. The reciprocating screw is connected to the output end of the dual-axis motor through a keyway.

[0014] This utility model provides a device for monitoring and breaking up ice on river surfaces, which has the following beneficial effects:

[0015] This utility model provides a river ice monitoring and ice-breaking device. Through the coordinated arrangement of a top plate, a lifting plate, and a lifting mechanism, the height of the lifting plate can be adjusted by changing the height of the lifting mechanism to adapt to different river water levels. Furthermore, mounting holes on the lifting plate allow for the installation of corresponding detection equipment, such as flow meters and ultrasonic thickness gauges, to monitor the flow velocity and thickness of the floating ice, enabling timely responses.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a river ice monitoring and ice breaking device, including a top plate 1, a lifting plate 2 and a lifting mechanism. The upper surface of the top plate 1 is fixedly connected to a mounting base 3, which is fixedly installed below the bridge deck.

[0022] Both sides of the lifting plate 2 are provided with rotating rods 4. The bottom of the rotating rods 4 is fixedly connected to a connecting chain 5. The bottom of the connecting chain 5 is fixedly connected to an ice-breaking hook 6 for breaking floating ice. The middle of the lifting plate 2 is provided with a driving mechanism, which is connected to the rotating rods 4 to drive the rotating rods 4 to rotate. One side of the lifting plate 2 is provided with a mounting hole 16 for installing a monitoring device.

[0023] The top plate 1 is connected to the mounting base 3 by bolts. The top plate 1 has a transverse through groove. When the mounting base 3 is fixed to the top plate 1, the position of the mounting base 3 can be adjusted laterally to adapt to more situations. The drive mechanism drives the rotating rods 4 on both sides to rotate. When the rotating rods 4 rotate, they will drive the connecting chain 5 at one end to rotate, which will further drive the ice-breaking hook 6 at one end to rotate, so that the ice-breaking hook 6 collides with the floating ice and breaks the floating ice. The bottom of the mounting hole 16 can be used to install the required equipment to monitor the floating ice on the river surface. The top plate 1 has notches and protrusions on both sides, so that the top plate 1 can be spliced ​​laterally to adapt to different situations.

[0024] The lifting mechanism is located on the lower surface of the top plate 1 and connected to the lifting plate 2 to control the height of the lifting plate 2.

[0025] In this embodiment, as a preferred solution, the lifting mechanism includes a slider 7 and a connecting rod 8. The slider 7 is slidably disposed on the lower surface of the top plate 1. The connecting rod 8 is rotatably connected to the bottom of the slider 7 via a rotating shaft. The other end of the connecting rod 8 is rotatably connected to the upper surface of the lifting plate 2 via a rotating shaft. The sliders 7 and the connecting rods 8 are grouped in pairs, and the middle of the two connecting rods 8 are connected by a rotating shaft. A drive motor 9 is fixedly connected to the lower surface of the top plate 1. A rotating shaft 10 is fixedly connected to the output end of the drive motor 9. The rotating shaft 10 passes through the slider 7. The surface of the rotating shaft 10 is provided with threads in opposite directions. The two sliders 7 are respectively adapted to the threads on both sides.

[0026] The drive motor 9 drives the rotating shaft 10 at the output end. The rotating shaft 10 has two threads in opposite directions, which are connected to two sliders 7 respectively. When the rotating shaft 10 rotates, it will drive the two sliders 7 to move towards or away from each other, thereby driving the connecting rod 8 at the bottom of the sliders 7 to move. The two connecting rods 8 form an X shape. When the sliders 7 move away from each other, the connecting rod 8 will lift up, thereby lifting the bottom lifting plate 2 and raising the height of the lifting plate 2. When the sliders 7 move closer to each other, the connecting rod 8 will move down, thereby lowering the bottom lifting plate 2. The connecting rods 8 are in pairs, and each pair is equipped with a drive motor 9 at the top. The drive motor 9 is a stepper motor, which can control the rotation angle of the rotating shaft 10, making the adjustment of the height of the lifting plate 2 more accurate and preventing the lifting plate 2 from tilting.

[0027] In this embodiment, as a preferred option, the drive mechanism includes a dual-axis motor 11, a reciprocating screw 12, and a drive wheel 13. The dual-axis motor 11 is fixedly connected to the upper surface of the lifting plate 2. The reciprocating screw 12 is connected to the output end of the dual-axis motor 11 through a keyway. The drive wheel 13 is fixedly connected to one end of the reciprocating screw 12 to drive the rotating rod 4 to rotate. A synchronous belt 14 is sleeved on the surface of the drive wheel 13. A driven wheel 15 is fixedly connected to one side of the rotating rod 4. The other end of the synchronous belt 14 is sleeved with the driven wheel 15 to drive the driven wheel 15 to rotate.

[0028] During the rotation of the dual-axis motor 11, the output shaft drives the drive wheel 13 to rotate. The drive wheel 13 is connected to the driven wheel 15 through the synchronous belt 14. When the drive wheel 13 rotates, it drives the driven wheel 15 to rotate as well. The driven wheel 15 drives the rotating rod 4 to rotate, so that the rotating rod 4 drives the ice-breaking hook 6 at one end to break the floating ice.

[0029] In this embodiment, as a preferred option, a groove 17 is provided in the middle of the upper surface of the lifting plate 2, and a sliding plate 18 is threadedly connected to the surface of the reciprocating screw 12. The sliding plate 18 passes through the groove 17 and is guided to the groove 17. A guide plate 19 is rotatably connected to the bottom of the sliding plate 18 to push the middle floating ice to move outward. The side wall of the guide plate 19 is provided with a plurality of guide grooves 20 opened along the water flow direction to reduce water flow resistance.

[0030] During the rotation of the output shaft of the dual-axis motor 11, the sliding plate 18 meshes with the surface of the reciprocating screw 12, allowing the sliding plate 18 to slide on the surface of the reciprocating screw 12. The slide groove 17 restricts the movement direction of the sliding plate 18, making the movement of the sliding plate 18 smoother. The sliding plate 18 is connected to the guide plate 19. An angle limiting mechanism is provided at the connection position between the guide plate 19 and the sliding plate 18 to limit the rotation angle of the guide plate 19, so as to prevent the guide plate 19 from rotating continuously when the water flow is too large. During the lateral movement of the guide plate 19, the floating ice in the middle will be pushed to both sides, so that the ice-breaking hooks 6 on both sides can break the floating ice. The guide grooves 20 on both sides can reduce the impact of the water flow on the guide plate 19.

[0031] In this invention, the working steps of the device are as follows:

[0032] 1. When using, install the top plate 1 under the bridge deck in a location where floating ice is likely to appear. If the length needs to be extended, splice the two top plates 1 together. After the top plate 1 is installed, install the required monitoring device in the mounting hole 16 on the lifting plate 2.

[0033] 2. Adjust the height of the lifting plate 2 according to the height of the river surface to meet the requirements;

[0034] 3. After floating ice appears in the river, start the dual-shaft motor 11 to drive the output shafts at both ends to rotate, and break the floating ice through the ice-breaking hooks 6 at both ends and the guide plate 19 at the bottom.

[0035] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
