Description

Technical Field

[0001] The present application relates to the technical field of gate de-icing in water conservancy projects, and in particular to a gate de-icing device and a gate de-icing method. Background Art

[0002] In winter, in low-temperature environments, many places with gates, such as water conservancy project hubs and water delivery channels, often have ice formed in front of the gates due to low temperatures and relatively stable water levels. In the presence of ice, the normal opening and closing of the gates will be affected, so ice melting devices are needed to ensure the safety and normal opening and closing of the gates.

[0003] At present, most common ice melting methods have certain limitations. For example, although the submersible pump method can accelerate the melting of ice by pumping or draining water to stir the water surface and enhance the fluidity of the water body, its ice melting speed is difficult to meet emergency needs when the ice layer is thick or the temperature is extremely low.

[0004] However, in actual use, heating or bubbling methods have also been proven to be unable to quickly and effectively break the ice layer, making it difficult to meet the requirements for rapid ice melting to restore normal operation of the gate in emergency situations. Summary of the invention

[0005] In order to effectively improve the efficiency of breaking the ice layer, the present application provides a gate ice melting device and an ice melting method.

[0006] On the one hand, the present application provides a gate ice melting device, which adopts the following technical solution: A gate ice melting device, comprising: A gate chamber section, on which a gate is slidably mounted; A crossbeam, located at the front side of the gate and slidably mounted on the gate chamber section; A lifting assembly is arranged on the lock chamber section and is used to detect the ice condition of the water surface in front of the lock gate and drive the crossbeam to rise and fall; A crushing assembly, disposed on the crossbeam and used for initially crushing the ice layer; The rotating component is arranged on the crushing component and is used for crushing ice cubes.

[0007] By adopting the above technical solution, the lifting component detects the ice condition of the water surface in front of the gate. When the water surface is frozen, the lifting component drives the crossbeam down to the ice surface position. The coordinated use of the crushing component and the rotating component can quickly crush and stir the ice, thereby easily improving the crushing efficiency of the ice layer and then easily improving the ice melting efficiency.

[0008] Optionally, a mounting groove is provided inside the crossbeam along its length direction, and the crushing assembly includes: A driving motor is fixed on the crossbeam; A cam, coaxially connected to the output shaft of the driving motor; A connecting plate is located in the mounting groove, and the cam is located above the connecting plate; A plurality of vibration rods are arranged along the length direction of the connecting plate, and one end of the vibration rod is fixedly connected to the connecting plate; A plurality of pressure-bearing springs are arranged along the length direction of the connecting plate, and two ends of the pressure-bearing springs are respectively fixedly connected to the connecting plate and the mounting groove. In an initial state, the pressure-bearing springs are in a natural state.

[0009] By adopting the above technical solution, the output shaft of the driving motor drives the cam to rotate, the tip of the cam squeezes the connecting plate to move downward, the connecting plate squeezes the pressure spring, the compression amount of the pressure spring increases, and the elastic force is accumulated, and the energy is released when the cam leaves; The cam can periodically contact and push the connecting plate when it rotates, thereby converting the rotational motion into the up and down reciprocating motion of the connecting plate. The connecting plate drives the vibration rod to move, and the vibration rod moves back and forth. The vibration rod repeatedly knocks on the ice layer. The vibration can destroy the structure of the ice layer, making it loose and making the ice layer easy to break, thereby improving the efficiency of ice crushing.

[0010] Optionally, the vibration rod is hollow inside, and the rotating assembly includes: Transmission unit, including: A detection telescopic rod is fixedly arranged in the installation groove, and a movable end of the detection telescopic rod is fixedly connected to the connecting plate; The movable telescopic rod has a fixed end fixedly connected to the crossbeam, and the rodless cavity is connected to the rodless cavity of the detection telescopic rod through a drainage tube, and air flows in the drainage tube; The rotating part is arranged on the movable telescopic rod and is used for crushing ice cubes.

[0011] By adopting the above technical solution, the tip of the cam squeezes the connecting plate to move downward, the connecting plate squeezes the movable end of the detection telescopic rod to move, the internal volume of the rodless cavity of the detection telescopic rod is reduced, the air in the rodless cavity of the detection telescopic rod enters the rodless cavity of the movable telescopic rod through the drainage tube, the air squeezes the movable end of the movable telescopic rod to move, the movable end of the movable telescopic rod drives the rotating part to move out of the vibration rod, the rotating part further crushes the ice cubes, and the ice melting efficiency is further improved; Conversely, when the tip of the cam leaves the connecting plate, the connecting plate moves upward under the elastic force of the pressure spring, and the movable ends of the detection telescopic rod and the movable telescopic rod are reset, so that the rotating part can approach or move away from the ice layer as the movable telescopic rod is extended or retracted, thereby realizing the spiral rise or fall to crush the ice cubes, and can further crush the ice cubes, thereby facilitating the melting of the ice layer.

[0012] Optionally, one end of the vibration rod away from the connecting plate is open, and the rotating part includes: A rotating motor is fixedly mounted on the movable end of the movable telescopic rod through a support plate; A plurality of rotating rods corresponding to the plurality of vibrating rods one by one, the rotating rods being inserted into the vibrating rods and being coaxially fixed with a cutting wheel; A plurality of driving gears corresponding to the plurality of rotating rods one by one, and the driving gears are coaxially fixed on the rotating rods; The intermediate gear is coaxially fixedly connected with the output shaft of the rotating motor, wherein the intermediate gear and the plurality of driving gears are jointly sleeved with a chain.

[0014] Optionally, a pressure cone is fixedly provided at one end of the rotating rod away from the driving gear, and in an initial state, the bottom end of the pressure cone is matched with the open end of the vibration rod.

[0015] By adopting the above technical solution, the conical design of the pressure cone makes it easier to cut into and crush ice when it contacts the ice layer. At the same time, since the pressure cone is closely matched with the vibration rod, when the vibration rod vibrates, the pressure cone can drive the cutting wheel to cut the ice layer more effectively, thereby improving the cutting efficiency and accuracy.

[0016] Optionally, a heating tube is provided in the pressing cone, and the heating tube is fixedly mounted on the inner wall of the pressing cone and spirally arranged along the conical surface of the pressing cone.

[0017] By adopting the above technical solution, the spiral setting of the heating tube in the pressing cone ensures that the heat can be evenly distributed on the cone surface of the pressing cone. When the pressing cone contacts the ice layer, the heat can be quickly transferred to the ice layer, accelerating the melting process of the ice layer, thereby significantly improving the ice melting efficiency.

[0018] Optionally, the lifting assembly includes: An infrared sensor is fixed on the crossbeam and is used to output an ice signal on the water surface; A controller is fixedly mounted on the lock chamber section, and the infrared sensor, the rotating motor and the driving motor are all electrically connected to the controller; Two hydraulic cylinders are provided, the movable ends of the two hydraulic cylinders are respectively fixedly connected to the two ends of the crossbeam, and the fixed ends are fixedly connected to the gate chamber section, and the hydraulic cylinders are electrically connected to the controller.

When the water surface freezes, the wavelength and energy of the reflected infrared rays change, and the infrared sensor outputs a water surface freezing signal to the controller. The controller responds to the signal output by the infrared sensor and controls the telescopic end of the hydraulic cylinder to move downward, thereby driving the crossbeam to move downward, so that the ice melting equipment can accurately locate the water surface position where ice melting is required, thereby improving the accuracy and efficiency of ice melting.

[0020] Optionally, the pressing cone is made of metal.

[0021] By adopting the above technical solution, metal is a good conductor of heat and can quickly transfer the heat generated by the heating tube to the ice layer.

[0023] By adopting the above technical solutions, the ice melting efficiency is improved from detecting the ice layer to positioning equipment, breaking ice, crushing ice and then melting ice.

[0024] Optionally, after the ice melting step S5, the following steps are further included: S6 Cooling: After the ice layer is completely melted, the controller controls the rotating motor to stop working, and the hydraulic cylinder lifts the crossbeam to lift the crushing assembly and the rotating assembly out of the water.
