An inclined rod 45 is fixedly connected to the circumference of the rotating rod 43. The inclined rod 45 is located on the displacement trajectory of the pressing rod 41. By rotating the fan blade 44, wind force is generated to blow air onto the housing 2 and dissipate heat from the hydraulic oil.

[0028] A torsion spring 46 is fixedly connected to the circumferential surface of the rotating rod 43. The end of the torsion spring 46 away from the rotating rod 43 is fixedly connected to the bottom of the cylindrical rod 42. The design of the torsion spring 46 is conducive to the automatic reset when the rotating rod 43 is not squeezed.

[0029] The fan blades 44 are located at the top of the housing 2. Several fan blades 44 are provided, and several fan blades 44 are arranged in a circumferential array on the circumferential surface of the rotating rod 43. The provision of several fan blades 44 is conducive to providing stable heat dissipation.

[0030] In this embodiment, the interior of the housing 2 is divided into two parts by an isolation plate 36. An oil inlet pipe 37 runs through the left side of the housing 2, supplying hydraulic oil into the housing 2. A water inlet pipe 38 runs through the right side of the housing 2, supplying water into the housing 2. The water and oil are separated by the isolation plate 36. The water is used to cool and exchange heat with the hydraulic oil, reducing the impact on the hydraulic station equipment and minimizing the risk of equipment damage due to high temperatures. This saves energy in the hydraulic station. Starting the motor 31 causes the long rod 32, circular plate 33, telescopic rod 34, and stirring plate 35 to rotate. The long rod 32, circular plate 33, telescopic rod 34, and stirring plate 35 are equipped with multiple... One part is located in hydraulic oil, and the other part is located in water. The telescopic rod 34 has a certain degree of flexibility. When the telescopic rod 34 rotates with the motor 31, it will cause the telescopic end of the telescopic rod 34 to swing out and rotate, which in turn causes the stirring plate 35 to swing out and rotate. Through centrifugal force, the stirring plate 35 rotates, stirring the oil and water separately, so that the oil and water can exchange heat evenly. Through the rotation of the telescopic rod 34 and the swinging of the stirring plate 35, the hydraulic oil and water can be effectively separated and stirred, so that they can exchange heat evenly. Even heat exchange can ensure that the temperature of the hydraulic oil and water is maintained within an appropriate range, which helps to improve thermal efficiency, reduce heat loss, and thus achieve the purpose of energy saving. Centrifugal stirring can achieve high The high-speed rotation pushes the hydraulic oil to the periphery, thereby achieving a more uniform temperature distribution within the hydraulic system. Due to centrifugal force, the high-temperature and low-temperature regions of the oil can exchange heat more quickly, helping to reduce temperature differences. This is crucial for the viscosity stability of the hydraulic oil, as excessive temperature differences can lead to uneven oil viscosity, affecting the efficiency and stability of the hydraulic system. When the motor 31 rotates, it drives the conveyor belt 312 to rotate, which in turn drives the rotating shaft 311 to rotate. The rotating shaft 311 then drives the actuating rod 313 to rotate. The push rod 316 is positioned on the movement trajectory of the actuating rod 313. The movement of the actuating rod 313 compresses the push rod. Push rod 316 pushes the pressure chamber 315 inwards, which in turn pushes the other end of push rod 317 outwards. The push rod 317 then pushes out the vibrating plate 318, which is located on the side of the housing 2, on the side where hydraulic oil is stored. When the vibrating plate 318 is pushed out, it vibrates the housing 2 containing hydraulic oil. Air bubbles, foam, and impurities in the hydraulic oil may cause a decrease in oil performance, especially the oil transmission efficiency and lubrication effect. By tapping the hydraulic housing 2 with the vibrating plate 318, air bubbles in the oil can be eliminated, reducing air accumulation and thus improving the performance of the oil.

[0031] The vibration plate 318 pushes out, causing the extrusion rod 41 to move closer to the inclined rod 45. The inclined rod 45 is located on the movement trajectory of the extrusion rod 41. When the extrusion rod 41 moves, it will squeeze the inclined rod 45, causing the inclined rod 45 to rotate. The rotation of the inclined rod 45 will drive the rotating rod 43 to rotate, which in turn will drive the fan blades 44 to rotate. The rotation of the fan blades 44 will generate wind. The fan blades 44 are located at the top of the box 2, and the wind generated by the fan blades 44 will blow directly onto the box 2 to remove heat. The wind generated by the fan blades 44 blows directly onto the box 2 of the blast furnace hot blast stove, helping to carry away the hot air, effectively reducing heat accumulation, reducing cooling requirements, and thus reducing the use of additional energy. Mechanical transmission can achieve precise control of wind force, avoiding the negative impact of excessively high or low temperatures on the operation of the blast furnace, and improving the overall operating efficiency of the system.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
