[0032] A cooling tower protection device comprises a protection shell body 1 and a fan 2, wherein the fan 2 is arranged inside the protection shell body 1, a protection mechanism 3 for waterproofing the fan 2 is arranged outside the protection shell body 1, and a protection component 4 for dustproofing the fan 2 is arranged on the top of the protection shell body 1;

[0033] The protective mechanism 3 includes a waterproof shell 301, a slide groove 302, a first spring 303, a slide rod 304, a trapezoidal block 305 and a hook column 306. The waterproof shell 301 is arranged above the protective shell body 1, the slide groove 302 is opened at the top of the protective shell body 1, the first spring 303 is welded to the inner wall of the slide groove 302, the slide rod 304 is slidably connected to the inside of the protective shell body 1, the trapezoidal block 305 is welded to one end of the slide rod 304, the hook column 306 is welded to the bottom of the waterproof shell 301, one end of the first spring 303 is welded to the side wall of the trapezoidal block 305, and the trapezoidal block 305 and the hook column 306 are used in conjunction with each other.

[0035] Specifically, Figure 1 As shown, a sealing ring 9 is bonded to the bottom of the protective shell body 1 to improve the sealing performance between the protective shell body 1 and the top of the cooling tower. The sealing ring 9 is made of silicone rubber.

[0036] Specifically, Figure 6 As shown, a circular plate 10 is welded at one end of the slide rod 304 to facilitate the user to pull the trapezoidal block 305 to move, and the circular plate 10 is made of stainless steel.

[0037] Specifically, Figure 6 As shown, a magnetic column 11 is bonded to the inner top wall of the slide slot 302 , and the magnetic column 11 is magnetically connected to the trapezoidal block 305 .

[0038] When in use, the user installs the protective shell body 1 in a suitable position through the external bolts and the mounting plate 7. When it is rainy outside, the user can pick up the waterproof shell 301, and then place the waterproof shell 301 on the top of the protective shell body 1, and then press down the waterproof shell 301. At this time, the bottom inclined surface of the hook column 306 will contact the inclined surface of the trapezoidal block 305, so that the trapezoidal block 305 moves to one side, and then the trapezoidal block 305 is adsorbed by the magnetic column 11 to prevent the trapezoidal block 305 from moving, and then the first spring 303 contracts, and then the waterproof shell 301 continues to be pressed down until the bottom of the hook column 306 contacts the bottom of the slide groove 302, and then the first spring 303 drives the trapezoidal block 305 to reset, thereby limiting the hook column 306. When it is sunny, the user can pull the circular plate 10 to contract the first spring 303, and then the trapezoidal block 305 moves and loses the limit on the hook column 306, and then the waterproof shell 301 can be removed.

[0039] Specifically, Figure 7 As shown, the protection component 4 includes a concave ring 401, a filter cartridge 402, an extension block 403, a guide column 404 and a second spring 405. The concave ring 401 is welded to the top of the protective shell body 1, the filter cartridge 402 is slidably connected to the inside of the concave ring 401, the extension block 403 is circumferentially distributed on the outer wall of the filter cartridge 402, the guide column 404 is welded to the top of the protective shell body 1, the second spring 405 is welded to the bottom of the extension block 403, the bottom of the second spring 405 is welded to the top of the protective shell body 1, and the top of the guide column 404 passes through the extension block 403 and is slidably connected to the extension block 403.

[0040] Specifically, Figure 7 As shown, the top of the guide column 404 is threadedly connected with a limiting portion 5 which prevents the extension block 403 from being separated from the guide column 404 , and the diameter of the limiting portion 5 is greater than the diameter of the guide column 404 .

[0041] Specifically, Figure 7 As shown, two triangular rings 6 are welded to the top of the concave ring 401 , and the right-angled sides of the triangular rings 6 are tightly fitted with the side walls of the filter cartridge 402 .

[0042] When a hard object from the outside is about to come into contact with the fan 2, the hard object will come into contact with the filter cartridge 402, thereby blocking the hard object. When the hard object comes into contact with the filter cartridge 402, the filter cartridge 402 will be lowered, and then the triangular ring 6 can scrape off the dust on the outer wall of the filter cartridge 402, and then the second spring 405 contracts and then stretches. When the second spring 405 stretches, the hard object will be pushed off. Because of the elastic force of the second spring 405, the filter cartridge 402 will move up and down several times. At this time, the dust on the filter cartridge 402 will also be shaken off, thereby improving the cleanliness of the filter cartridge 402. When the filter cartridge 402 moves up and down, the limiting portion 5 can prevent the extension block 403 from detaching from the guide column 404, thereby improving the stability of the device.

[0043] By adopting the above technical solution, the problem that the existing cooling tower protection device protects the fan 2 through a protection net when in use, but when it rains, rainwater will come into contact with the fan 2, causing the fan 2 to short-circuit or rust.

[0044] Working principle: When in use, the user installs the protective shell body 1 in a suitable position through external bolts and the mounting plate 7. When it is rainy outside, the user can pick up the waterproof shell 301, and then place the waterproof shell 301 on the top of the protective shell body 1, and then press down the waterproof shell 301. At this time, the bottom inclined surface of the hook column 306 will contact the inclined surface of the trapezoidal block 305, so that the trapezoidal block 305 moves to one side, and then the trapezoidal block 305 is adsorbed by the magnetic column 11 to prevent the trapezoidal block 305 from moving, and then the first spring 303 contracts, and then the waterproof shell 301 continues to be pressed down until the bottom of the hook column 306 contacts the bottom of the slide groove 302, and then the first spring 303 drives the trapezoidal block 305 to reset, thereby limiting the hook column 306. When it is sunny, the user can pull the circular plate 10 to make the first spring 303 Contraction, then the trapezoidal block 305 moves to lose the limit on the hook column 306, and then the waterproof shell 301 can be removed. When a hard object from the outside is about to contact the fan 2, the hard object will contact the filter cartridge 402, thereby blocking the hard object. When the hard object contacts the filter cartridge 402, the filter cartridge 402 will drop, and then the triangular ring 6 can scrape off the dust on the outer wall of the filter cartridge 402. Then the second spring 405 contracts and then stretches again. When the second spring 405 stretches, the hard object will be pushed off. Because of the elastic force of the second spring 405, the filter cartridge 402 will move up and down several times. At this time, the dust on the filter cartridge 402 will also be shaken off, thereby improving the cleanliness of the filter cartridge 402. When the filter cartridge 402 moves up and down, the limiting portion 5 can prevent the extension block 403 from separating from the guide column 404, thereby improving the stability of the device.
