[0002] Reservoir gate ice-breaking control devices are mainly used for ice-breaking operations in reservoir gate areas during winter. They employ mechanical or hydraulic devices to drive the ice-breaking head in reciprocating motion to prevent the gate from failing to open or close properly due to excessively thick ice. However, this device often faces a major problem in practical applications: due to variations in ice thickness, the device may encounter different levels of resistance during its movement, resulting in torque imbalance. This torque imbalance can cause the ice-breaking device to skew or jam, thus affecting ice-breaking efficiency and the equipment's lifespan. Summary of the Invention

[0029] like Figure 1 As shown, the reservoir gate ice-breaking control device of this application includes an ice-blade mechanism 1, an adjustable linkage mechanism 2, a guide rail 3, a drive arm 4, and a counterweight 5. The ice-blade mechanism 1 is installed at the bottom of the reservoir gate for effectively cutting the ice layer. One end of the adjustable linkage mechanism 2 is connected to the ice-blade mechanism 1, and the other end is connected to the drive arm 4. Its length can be adjusted to adapt to changes in ice thickness, ensuring that the ice-blade mechanism 1 is in perpendicular contact with the ice surface. The guide rail 3 is located on both sides of the ice-blade mechanism 1 to ensure that the ice-blade mechanism 1 moves along a fixed path, preventing deviation or jamming. The drive arm 4 is fixed to the reservoir gate via a rotating shaft, driving the ice-blade mechanism 1 to move up and down. It is also connected to the adjustable linkage mechanism 2 to transmit motion and maintain torque balance. The counterweight 5 is located at the end of the drive arm 4. By adjusting the weight, it balances the torque differences caused by changes in ice thickness, ensuring stable operation of the device.

[0030] The ice blade mechanism 1 is a sharp metal blade, typically made of high-strength material, with excellent cutting performance. This blade is fixed to the bottom of the reservoir gate, and its shape and angle design ensure effective ice cutting. The adjustable linkage mechanism 2 consists of several connecting rods, each hinged together and equipped with adjusting bolts or telescopic joints to allow for length adjustment. This ensures that the ice blade mechanism 1 maintains perpendicular contact with the ice surface under varying ice thicknesses. The guide rails 3 are a pair of parallel guide rails fixed to the structures on both sides of the reservoir gate. They are typically made of wear-resistant material, ensuring that the ice blade mechanism 1 moves smoothly along a predetermined trajectory, preventing skewing or jamming due to lateral forces. The drive arm 4 is fixed to the reservoir gate via a rotating shaft that rotates and drives the drive arm 4. One end of the drive arm 4 is connected to the ice blade mechanism 1, and the other end is connected to the counterweight 5, transmitting force to the ice blade mechanism 1 through the movement of the rotating arm. The counterweight 5 is an adjustable weight block 14, which is suspended or fixed at the end of the drive arm 4. Its mass can be adjusted according to the actual ice thickness to ensure that the drive arm 4 can always maintain a stable torque balance when the ice thickness changes.

[0031] Specifically, the ice blade mechanism 1 can be securely installed at the bottom of the reservoir gate using bolts or other fasteners, ensuring it will not fall off or be damaged during operation. The adjustable linkage mechanism 2 can be implemented by setting threaded holes and corresponding adjusting nuts between the rods, allowing the rod length to be changed by rotating the nuts. The guide rail 3 can be fixed to the side of the reservoir gate by welding or screws, ensuring the guide rail's positional accuracy and rigidity. The drive arm 4 is fixed via a rotating shaft, on which bearings can be installed to reduce friction. The counterweight 5 can be designed to be detachable, allowing users to add or remove the number or size of the counterweight blocks 14 according to actual needs.

[0032] This device, through the effective combination of the aforementioned components, solves the problem of torque imbalance caused by variations in ice thickness. Specifically, the ice blade mechanism 1 is installed at the bottom of the reservoir gate and, through the adjustment of the adjustable linkage mechanism 2, always maintains perpendicular contact with the ice surface. This adjustment function ensures that the ice blade mechanism 1 can closely adhere to the ice surface regardless of changes in ice thickness, guaranteeing cutting efficiency. The guide rail 3 ensures the straightness and stability of the ice blade mechanism 1 during movement, preventing skewing or jamming. The design of the drive arm 4 and the counterweight 5 maintains torque balance in the mechanical movement, ensuring smooth operation of the entire ice-breaking control device even under uneven ice thickness conditions, greatly improving the device's reliability and service life.

[0033] like Figure 1 As shown, in one embodiment, the ice-breaking mechanism 1 of a reservoir gate ice-breaking control device of this application includes at least two cutting edges 6, which are uniformly distributed laterally. Specifically, the distribution of these cutting edges 6 ensures uniform cutting at different horizontal positions, thereby reducing skewing or jamming caused by uneven local force. Through this design, the ice-breaking mechanism 1 can operate effectively under a wide range of ice thicknesses and distributions, ensuring the overall stability and reliability of the device.

[0034] In one embodiment, the number, spacing, and shape of the cutting blades 6 can be adjusted according to actual needs to adapt to the specific conditions of different reservoirs. For example, each cutting blade 6 can be made of a high-performance, corrosion-resistant material to ensure efficient cutting capability during long-term use. The cutting blades 6 are bolted to the main frame of the ice-breaking mechanism 1, which is connected to the gate body via connectors, ensuring a compact and stable overall structure. In this way, the ice-breaking mechanism 1 can not only be evenly distributed throughout the working area but also reliably perform ice-breaking tasks under different environmental conditions.

[0035] Continue to refer to Figure 1In one embodiment, the adjustable linkage mechanism 2 of the reservoir gate ice-breaking control device of this application includes two parallel telescopic rods 7. An adjusting bolt 8 is provided between the outer tube and inner rod of each telescopic rod 7. By adjusting the position of the adjusting bolt 8, the length of the telescopic rod 7 can be changed, allowing the ice blade mechanism 1 to perpendicularly contact the ice layer and precisely adapt to ice layers of different thicknesses. To facilitate quick adjustment by operators according to the actual ice thickness, a scale 9 is provided on the outside of the telescopic rod 7. Operators can accurately grasp the extension length of the telescopic rod 7 by reading the scale 9, avoiding torque imbalance caused by misoperation. The outer tube and inner rod of the telescopic rod 7 are connected by threads, and the adjusting bolt 8, through engagement with the threaded hole on the inner rod, realizes the length adjustment of the telescopic rod 7. Simultaneously, the scale 9 is fixed on the outer tube of the telescopic rod 7, and the scale is clearly visible.

[0036] For example, specifically, the adjusting bolt 8 is installed on the side of the outer tube, with one end matching the threaded hole on the inner rod and the other end exposed for easy manual adjustment. When it is necessary to change the length of the telescopic rod 7, the operator can push or pull the inner rod by rotating the adjusting bolt 8 to achieve the desired length. The scale 9 is set longitudinally along the outer tube of the telescopic rod 7, with each graduation representing a certain length change. The operator can accurately read and adjust the extension length of the telescopic rod 7 according to actual needs.

[0037] like Figure 2 As shown, in one embodiment, a reservoir gate ice-breaking control device of this application includes a guide rail 3, which is used to ensure that the ice blade mechanism 1 moves stably along a preset path during movement, avoiding deviation or jamming. The guide rail 3 consists of two symmetrically arranged linear guide rails 10, each guide rail being equipped with multiple rollers 11, which are in close contact with the guide rail. The guide rails are installed on both sides of the ice blade mechanism 1 to ensure that the ice blade mechanism 1 maintains stable linear movement throughout the ice-breaking process. The number of rollers 11 on each guide rail can be adjusted according to actual needs, but it must be ensured that sufficient support force can be provided under any operating conditions.

[0038] In one embodiment, these rollers 11 are made of a self-lubricating material, possessing excellent friction-reducing properties. This reduces friction during rolling while improving the overall operational stability and reliability of the device. The choice of self-lubricating material can further reduce maintenance frequency and costs, extending the device's service life. For example, rollers 11 can be made of high-performance polymer materials, such as polyoxymethylene (POM) or ultra-high molecular weight polyethylene (UHMW-PE). These materials not only have good self-lubricating properties but also withstand low-temperature environments, ensuring normal operation under cold conditions. Furthermore, the rollers 11 are typically mounted using rolling bearings. The embedded bearings allow the rollers 11 to rotate freely, further reducing friction and improving the overall system performance.

[0039] Return to reference Figure 1 In one embodiment, the drive arm 4 of the reservoir gate ice-breaking control device of this application is internally equipped with a hydraulic cylinder 12, which drives the ice-blade mechanism 1 to move up and down by the pressure of hydraulic oil. This design enables the device to respond quickly to external control signals and ensures stable operation under different working conditions. Specifically, the space inside the drive arm 4 is designed to accommodate the size and shape of the hydraulic cylinder 12, ensuring that the hydraulic cylinder 12 has sufficient space and stability during operation.

[0040] In addition, to improve system stability and reduce vibration, an elastic buffer pad 13 is installed at the connection between the hydraulic cylinder 12 and the drive arm 4. This buffer pad can absorb some vibration during operation and reduce the impact caused by torque changes. Specifically, the buffer pad is placed on the contact surface between the hydraulic cylinder 12 and the drive arm 4, serving as a shock absorber and protector.

[0041] For example, the drive arm 4 can be made of a high-strength alloy material, with an internal sealed cavity to accommodate the hydraulic cylinder 12. The hydraulic cylinder 12 is filled with hydraulic oil, and the oil pressure is regulated by an external control system to drive the ice blade mechanism 1 to move up and down. Meanwhile, the buffer pad can be made of a material with good elasticity and wear resistance, such as polyurethane or rubber, and is fixed between the contact surfaces of the hydraulic cylinder 12 and the drive arm 4 by fasteners.

[0042] refer to Figure 3 In one embodiment, the counterweight 5 of the reservoir gate ice-breaking control device of this application includes two symmetrically arranged adjustable counterweight blocks 14. The design of these two counterweight blocks 14 enables the entire device to maintain torque balance during the ice-breaking process. Several adjustment holes 15 are provided on the counterweight blocks 14. By selecting and installing the adjustment holes 15 at different positions, the user can flexibly adjust the weight of the counterweight blocks 14. This design not only adapts to different ice thickness variations but also ensures good torque balance throughout the entire range of ice thickness changes.

[0043] The adjustment holes 15 on each counterweight 14 are arranged at equal intervals. The spacing of these holes is optimized to precisely match common ice thickness variations. For example, in practical applications, if the ice thickness changes, the user can select the appropriate adjustment hole 15 for installation based on the actual ice thickness. The equal spacing of the adjustment holes 15 ensures that the weight of the counterweight 14 can be accurately adjusted with each adjustment, thereby guaranteeing that the device is in optimal balance after each adjustment.

[0044] In one embodiment, the counterweight 14 is installed at one end of the balance arm, connected to the ice-breaking mechanism. Adjustment holes 15 are evenly distributed along the length of the counterweight 14. This design allows operators to quickly select and install appropriate adjustment holes 15 under ice thickness conditions. The installation process involves passing a fastener through the corresponding adjustment hole 15 on the counterweight 14 and then fixing it to the corresponding position on the balance arm to ensure that the counterweight 14 is securely installed and performs its adjustment function.

[0045] In actual operation, when this device is used, firstly, an ice-cutting mechanism 1 is installed at the bottom of the reservoir gate, which can cut the ice layer during the closure of the reservoir gate. The ice-cutting mechanism 1 needs to maintain perpendicular contact with the ice surface, for which an adjustable linkage mechanism 2 is designed. One end of this linkage is connected to the ice-cutting mechanism 1, and the other end is connected to the drive arm 4, and its length can be adjusted to adapt to changes in ice thickness. This adjustment function ensures that the ice-cutting mechanism 1 always remains in close contact with the ice surface, achieving effective cutting.

[0046] Furthermore, guide rails 3 are positioned on both sides of the ice-blading mechanism 1, providing a fixed movement path for it. This design effectively avoids potential skewing or jamming during the cutting process, ensuring stable operation of the device. The drive arm 4 is fixed to the reservoir gate via a rotating shaft, enabling it to drive the ice-blading mechanism 1 up and down. The drive arm 4 not only transmits motion but also connects to the adjustable linkage mechanism 2 to maintain torque balance throughout the system. Through this connection method, even at different operational stages, all components can coordinate and work together to complete the ice-breaking task.

[0047] Finally, a counterweight 5 is installed at the end of the drive arm 4. The weight of the counterweight 5 can be adjusted according to changes in ice thickness, thereby maintaining torque balance under various operating conditions. This not only reduces energy consumption during operation but also significantly improves the efficiency and safety of the device. Through the combined efforts of all these components, the entire ice-breaking control system can efficiently and reliably complete the ice-breaking task of the reservoir gate under various complex environmental conditions.

[0048] The exemplary systems and methods of the present invention have been specifically shown and described with reference to the above embodiments, which are merely examples of the best mode for implementing the systems and methods. Those skilled in the art will understand that various changes can be made to the embodiments of the systems and methods described herein without departing from the spirit and scope of the invention as defined in the appended claims when implementing the systems and / or methods.
