[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: a cooling tower top anti-freezing device, comprising a tower body 1, a tower spire 2 is fixedly connected to the top of the tower body 1, a plurality of fixed platforms 3 are fixedly connected to the outer wall of the tower spire 2, a push rod 4 is rotatably connected to the bottom of the fixed platform 3, a turntable 10 is rotatably connected to the output end of the push rod 4, a rotating plate 5 is fixedly connected to the lower surface of the turntable 10, a plurality of slide grooves 6 are opened inside the fixed platform 3, a card plate 8 is arranged inside the fixed platform 3, the outer wall of the card plate 8 is slidably connected to the inside of the slide groove 6, an arc groove 9 is arranged inside the card plate 8, a fixed plate 7 is fixedly connected to the lower surface of the fixed platform 3, the bottom of the card plate 8 is rotatably connected to the inside of the turntable 5, the side wall of the card plate 8 is rotatably connected to the inside of the fixed plate 7, a connecting component is arranged inside the tower spire 2, a thermal insulation layer 22 is arranged on the top of the tower spire 2, and a heat conducting ring 23 is arranged inside the thermal insulation layer 22.

[0025] Specifically, starting the push rod 4 will apply a push-pull force on the turntable 10. After the turntable 10 is subjected to the force, the push-pull turn plate 5 will be pushed and pulled, so that the turntable 5 and the turntable 10 will rotate at one end of the push rod 4 and change their own inclination angle. After the turntable 5 starts to rotate, the card plate 8 is pulled to push the card plate 8 to rotate in the side wall of the fixed plate 7 and the inside of the turntable 5. At the same time, the card plate 8 can slide in the slide groove 6 inside the fixed platform 3. The sliding of the card plate 8 can achieve the fixing or unlocking of the heating element. This structural design provides an efficient heating structure for the cooling tower anti-freezing device. It can quickly disassemble and assemble the heating element and flexibly adjust its contact state, thereby improving the maintenance efficiency. At the same time, the setting of the insulation layer 22 and the heat conductive ring 23 can maintain the temperature of the tower top for a long time, further improving the heating efficiency and ensuring the normal operation of the cooling tower.

[0026] Reference Figure 4 The connecting component includes a connecting platform 11, and the connecting component includes a connecting platform 11. The side wall of the connecting platform 11 is fixedly connected to the inside of the fixed platform 3. The side wall of the connecting platform 11 is fixedly connected to a slide rail 12. The slide rail 12 is slidably connected to a slide 14. The side wall of the connecting platform 11 is fixedly connected to a push rod 13. The output end of the push rod 13 is fixedly connected to the side wall of the slide 14. The side wall of the connecting platform 11 is fixedly connected to a top plate 16. A sliding window 15 is opened inside the connecting platform 11. A connecting column 17 is rotatably connected to the inside of the slide 14. A rotating block 18 is rotatably connected to the top of the connecting column 17. A pulley 19 is rotatably connected to the inside of the rotating block 18. The side wall of the pulley 19 is slidably connected to the side of the top plate 16. The side wall of the rotating block 18 is fixedly connected to a connecting frame 20. The side wall of the connecting frame 20 is fixedly connected to the side wall of the slide 14. A plurality of air ducts 21 are fixedly connected to the bottom of the connecting column 17.

[0027] Specifically, when the push rod 13 is started, it applies a push-pull force to the slide 14, causing it to slide on the outer wall of the slide rail 12. The sliding of the slide 14 simultaneously drives the connecting frame 20 to perform synchronous displacement inside the sliding window 15. The movement of the connecting frame 20 drives the rotating block 18 to move in parallel, and the movement of the rotating block 18 causes the pulley 19 inside it to slide and rotate on the side wall of the top plate 16. The top plate 16 has a slope design so that the connecting column 17 can rotate inside the slide 14. The movement of the slide 14 and the connecting column 17 enables the air duct 21 at the bottom to move and rotate. This accelerates the air circulation in the top area of ​​the cooling tower, thereby expanding the thermal circulation range of the heating element and further enhancing the heating effect on the top of the cooling tower. This design ensures the heating effect required for the normal operation of the cooling tower.

[0028] Working principle: when it is necessary to heat and freeze the top of the cooling tower, first start the push rod 4, which outputs a push-pull force to the turntable 10. After the turntable 10 is subjected to the force, it pushes and pulls the rotating plate 5, so that the rotating plate 5 and the turntable 10 rotate at one end of the push rod 4 and change their own inclination angle. While the rotating plate 5 rotates, it pulls the card plate 8, so that the card plate 8 rotates on the side wall of the fixed plate 7 and inside the rotating plate 5 and slides in the slide groove 6 inside the fixed platform 3. The sliding of the card plate 8 can fix or unlock the heating element by the arc groove 9, and at the same time achieves the effect of convenient disassembly. This structure can realize the rapid disassembly and assembly of the heating element, thereby improving the maintenance efficiency of the anti-freezing device. At the same time, the arrangement of the heat-conducting ring 23 and the thermal insulation layer 22 inside the spire 2 can prevent the cooling tower from freezing due to the temperature difference, causing ice to cause damage to the surrounding environment and personnel, which is beneficial to the cooling tower. The anti-freezing work provides an efficient heating structure. When the heating effect needs to be diffused, the push rod 13 is started. The push rod 13 outputs a push-pull force to the slide 14 to make it slide on the outer wall of the slide rail 12. While the slide 14 slides, it drives the connecting frame 20 of its side wall to synchronously move, that is, slide inside the sliding window 15. The connecting frame 20 can drive the rotating block 18 to make parallel movement. While the rotating block 18 moves, the pulley 19 inside it rotates inside it and slides on the side wall of the top plate 16. The inclined design of the top plate 16 makes the connecting column 17 driven to rotate inside the slide 14. Through the sliding of the slide 14 and the rotation of the connecting column 17, the air duct 21 at the bottom can be moved and rotated, thereby accelerating the air circulation at the top of the cooling tower, expanding the heat circulation range of the heating element, further improving the heating effect on the top of the cooling tower, and providing a guarantee for the normal operation of the cooling tower.
