[0037] 4. By deflecting the rotating top plate axially inward along the fixed axis, the resilient plug fixedly connected to the bottom of the rotating top plate will pass through the perforations on the surface of the filter screen, thereby cleaning the impurities accumulated inside the perforations of the filter screen outward.

[0038] 5. Through the rotation of the rotating top plate, it will also impact the surface of the filter screen, thereby vibrating and removing the dust or salt on the surface of the filter screen.

[0039] 6.

[0055] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, any combination of the following-described embodiments or technical features can form a new embodiment. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] Please refer to Figures 1 to 14 , the present invention provides a technical solution: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , it includes a motor 1 for driving the fan, and the outside of the fan 1 is connected to a machine shell 3 by bolts; among them, the motor 1 is an energy-saving motor.

[0057] The fixing mechanism 2 for fixedly installing the motor 1 and the housing 3 is provided at the bottom of the motor 1;

[0058] The cleaning mechanism 4 for filtering impurities and salt spray in the air flow is connected to the side of the housing 3 away from the motor 1.

[0059] The fixing mechanism 2 includes a base 21 which is slidably fitted to the bottom of the motor 1;

[0060] The fastening bolts 22 are used for threadedly fastening the base 21 and the motor 1 and are respectively threadedly connected to the base 21 and the motor 1;

[0061] An elastic telescopic rod 23 is fixedly installed inside the base 21;

[0062] The positioning plate 24 is used for positioning when the base 21 and the motor 1 have not been threadedly fastened, and the bottom is fixedly connected to the top end of the elastic telescopic rod 23; By fastening the motor 1 to the housing 3 with bolts, and then sliding the bottom of the motor 1 from right to left to fit into the top of the base 21. An elastic telescopic rod 23 is fixedly connected inside the base 21, and the top end of the elastic telescopic rod 23 is fixedly connected to the positioning plate 24. Therefore, when the motor 1 initially slides and fits on the base 21, its bottom will squeeze the positioning plate 24 downward, and at the same time the elastic telescopic rod 23 will be compressed. However, when the bottom of the motor 1 moves to the position where it fits with the top of the positioning plate 24, the elastic telescopic rod 23 will extend, so that the positioning plate 24 will play a role in initially limiting and positioning the motor 1, and then the motor 1 and the base 21 are fastened and connected by the fastening bolts 22.

[0063] An inner inclined plate 25 is fixedly installed at the central part of the top of the base 21, and the vertical end face of the inner inclined plate 25 is in extrusion fit with a fitting plate 26;

[0064] The return spring 28 is used for returning the fitting plate 26 and is fixedly connected to the end of the fitting plate 26 away from the inner inclined plate 25;

[0065] One end of the return spring 28 away from the fitting plate 26 is fixedly connected to a T-shaped plate 27. The inner wall of the T-shaped plate 27 is slidably fitted with the fitting plate 26, and the end of the T-shaped plate 27 away from the fitting plate 26 is fixedly connected to the housing 3;

[0066] A long strip plate 29 is connected inside the base 21 by the fastening bolts 22, and an insertion limiting plate 20 is inserted on the outside of the long strip plate 29;

[0067] The fastening sleeve 201 is used for limiting the insertion limiting plate 20 and is press-fitted on the outside of the insertion limiting plate 20. Since the outside of the motor 1 is fixedly connected to the machine housing 3 by bolts, when the motor 1 slides and fits from right to left along the top of the base 21, the machine housing 3 will also move towards the base 21. A T-shaped plate 27 is fixedly connected to the outside of the machine housing 3. Therefore, as the T-shaped plate 27 moves towards the base 21, the fitting plate 26 sliding and fitting inside it will be squeezed by the inner inclined plate 25. The inner inclined plate 25 is fixedly connected to the center of the top of the base 21, compresses the return spring 28 and is received into the T-shaped plate 27. The inside of the T-shaped plate 27 is filled with gas. Therefore, when the fitting plate 26 slides into the T-shaped plate 27, it will also compress the gas inside it. The compressed gas will move towards both ends of the inner cavity of the T-shaped plate 27 and squeeze the insertion limiting plate 20. Finally, the insertion limiting plate 20 will move outwards along the inner sliding groove 202, pass through the long strip plate 29, and then the fastening sleeve 201 is used to limit the insertion limiting plate 20, so as to play a role in firmly connecting the motor 1, the machine housing 3 and the base 21 pairwise.

[0068] An inner sliding groove 202 is formed inside the T-shaped plate 27. The inside of the inner sliding groove 202 is slidably fitted with the insertion limiting plate 20. One end of the insertion limiting plate 20 away from the fastening sleeve 201 is fixedly connected with a first magnetic block 203.

[0069] A second magnetic block 204 is in an attracting relationship with the first magnetic block 203 and is fixedly connected inside the T-shaped plate 27. The long strip plate 29 is installed inside the base 21 through fastening bolts 22. When the fitting plate 26 is received into the T-shaped plate 27, the insertion limiting plate 20 will also extend outwards along the inner sliding groove 202 synchronously. When the fitting plate 26 moves inwards to the position where it cannot move, the insertion limiting plate 20 also passes through the surface of the long strip plate 29 and extends outwards from the other side.

[0070] There is an attracting relationship between the first magnetic block 203 connected to the insertion limiting plate 20 and the second magnetic block 204 fixedly connected inside the T-shaped plate 27. The attraction between the two magnetic blocks plays a role in resetting the insertion limiting plate 20 when it is not squeezed by the compressed gas.

[0071] As Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14 shown, the cleaning mechanism 4 includes an impeller 42, and the central part of the impeller 42 is fixedly connected to the output end of the motor 1.

[0072] An air guiding frame 41 for guiding the air entering the interior of the casing 3, and both the air guiding frame 41 and the impeller 42 are arranged inside the casing 3;

[0073] The cleaning mechanism 4 further includes an air flow pipe 44, the air flow pipe 44 is fixedly connected to the outside of the casing 3, and a filter net 400 is fixedly connected to one end of the air flow pipe 44 away from the casing 3;

[0074] A support shaft seat 45 is fixedly connected to the top of the air flow pipe 44, and a fixed shaft 46 is fixedly connected to the inside of the support shaft seat 45;

[0075] A rotating top plate 47, which is used for impacting and penetrating the impurities on the filter net 400 and is rotatably connected to the fixed shaft 46;

[0076] Wherein, friction protrusions are arranged on the circumferential side of the rotating top plate 47 to increase the friction force with the air flow pipe 44, and a resilient plug 48 is fixedly connected to the bottom of the rotating top plate 47; in addition, when the equipment stops running, the rotating top plate 47 is deflected inward along the fixed shaft 46, so that the resilient plug 48 fixedly connected to the bottom of the rotating top plate 47 will pass through the perforations on the surface of the filter net 400, thereby playing a role in cleaning the impurities accumulated inside the perforations of the filter net 400 outward. At the same time, the rotating top plate 47 will also impact the surface of the filter net 400, thereby playing a role in vibrating and removing the dust or salt on the surface of the filter net 400. The inward deflection of the rotating top plate 47 also facilitates the operator to clean the inside of the air flow pipe 44.

[0077] A dehumidifying plate 49 and a desalting frame 40 are respectively inserted through the top of the air flow pipe 44, wherein the dehumidifying plate 49 is used for removing the moisture in the air;

[0078] At the bottom of the inner cavity of the desalting frame 40, there is a material receiving frame 403. A wet curtain board 402 is fixedly connected to the top of the material receiving frame 403. The wet curtain board 402 is used to remove the salt mist in the air. By starting the motor 1, the impeller 42 connected to its output end will rotate. Then, the outside air flow will enter the air flow pipe 44 through the filter net 400. The filter net 400 will filter the impurities floating in the air flow. In addition, a desalting frame 40 is arranged inside the air flow pipe 44. At this time, the air flow will pass through the conical holes 401 opened on the surface of the desalting frame 40. The inner diameter of the end of the conical hole 401 in contact with the wind is larger than that of the other end, so as to prevent the salt accumulated in a group from running out of the conical hole 401. At the same time, a wet curtain board 402 is also arranged inside the desalting frame 40. At this time, the salt mist in the air flow will be absorbed by the wet curtain board 402, so as to remove the salt mist contained in the air flow and avoid corroding the motor shaft and the impeller 42. Then, the air flow passing through the wet curtain board 402 and the desalting frame 40 will pass through the dehumidifying board 49, and the dehumidifying board 49 will absorb and remove the moisture in the air flow.

[0079] Conical holes 401 are opened on both sides of the desalting frame 40;

[0080] The output end of the motor 1 is connected to the machine shell 3 through a bearing. An external connecting shaft 43 is fixedly connected to the outer end face of the output end of the motor 1. A telescopic rod 404 is fixedly connected to the outside of the external connecting shaft 43;

[0081] The elastic ring plate 405 has a certain function of circular expansion and contraction, and its inner wall is fixedly connected to the telescopic rod 404.

[0082] The bottom of the air flow pipe 44 is inserted with a hollow frame 406. One end of the hollow frame 406 is slidably fitted with a plugging plate 407. The plugging plate 407 is fixedly connected to the bottom of the air flow pipe 44. One end of the hollow frame 406 close to the plugging plate 407 is open;

[0083] A clamping plate 408 is fitted in a nested manner at the end of the hollow frame 406 away from the plugging plate 407. A constant temperature part 409 is fixedly connected to one side of the inner cavity of the hollow frame 406 where the clamping plate 408 is located. The clamping plate 408 is fitted in a nested manner on the hollow frame 406, so the clamping plate 408 and the constant temperature part 409 can be removed to realize the replacement of the constant temperature part 409.

[0084] The bottom of the hollow frame 406 is extrusion-fitted with the outer side of the elastic ring plate 405. By the rotation of the motor shaft, the external shaft 43 connected to its outer end will rotate. A number of telescopic rods 404 are fixedly connected to the outer side of the external shaft 43. Therefore, when the rotation speed of the motor shaft increases, the centrifugal force of the telescopic rods 404 will become larger, causing the telescopic rods 404 to extend outwards. And the elastic ring plate 405 connected to the other end of the telescopic rod 404 will expand outwards. The elastic ring plate 405 will keep extruding the hollow frame 406 outwards. At this time, the hollow frame 406 will extend into the air flow pipe 44 from the bottom of the air flow pipe 44, and the opening of the hollow frame 406 will no longer be blocked by the blocking plate 407 and will remain open. Immediately afterwards, the temperature control element 409 arranged inside the hollow frame 406 will cool the inside of the air flow pipe 44, so as to cool the air entering the air flow pipe 44, and indirectly cool the motor 1, the impeller 42 and the motor shaft.

[0085] When the present invention is in use: First, the motor 1 is firmly connected to the machine shell 3 by bolts. Then, the bottom of the motor 1 is fitted and slid from right to left with the top of the base 21. An elastic telescopic rod 23 is fixedly connected to the inside of the base 21, and the top of the elastic telescopic rod 23 is fixedly connected to the positioning plate 24. Therefore, the initial sliding fit of the motor 1 on the base 21 causes its bottom to squeeze the positioning plate 24 downwards, and at the same time, the elastic telescopic rod 23 will be compressed. However, when the bottom of the motor 1 moves to the position where it is fitted with the top of the positioning plate 24, the elastic telescopic rod 23 will extend. At this time, the positioning plate 24 will perform a preliminary positioning process on the motor 1, and then the motor 1 and the base 21 will be firmly connected by the fastening bolt 22.

[0086] Since the outer side of the motor 1 is firmly connected to the machine shell 3 by bolts, during the process of the motor 1 sliding and fitting from right to left along the top of the base 21, the machine shell 3 will also move towards the base 21. A T-shaped plate 27 is fixedly connected to the outer side of the machine shell 3. Therefore, as the T-shaped plate 27 moves towards the base 21, the fitting plate 26 slidably fitted inside it will be squeezed by the inner inclined plate 25. The inner inclined plate 25 is fixedly connected to the center of the top of the base 21, compresses the return spring 28 and is received into the T-shaped plate 27. The inside of the T-shaped plate 27 is filled with gas. Therefore, when the fitting plate 26 slides into the T-shaped plate 27, it will also compress the gas inside it. The compressed gas will move towards both ends of the inner cavity of the T-shaped plate 27 and squeeze the inserted limiting plate 20. Finally, the inserted limiting plate 20 will move outwards along the inner chute 202, pass through the long strip plate 29, and then the inserted limiting plate 20 will be limited by the fastening sleeve 201, so as to firmly connect the motor 1, the machine shell 3 and the base 21 in pairs.

[0087] By starting the motor 1, the impeller 42 connected to its output end will rotate. Immediately afterwards, the outside air flow will enter the air flow pipe 44 through the filter net 400. The filter net 400 will filter out the impurities floating in the air flow. In addition, a desalting frame 40 is arranged inside the air flow pipe 44. At this time, the air flow will pass through the conical holes 401 formed on the surface of the desalting frame 40. At the same time, a wet curtain plate 402 is also arranged inside the desalting frame 40. At this time, the salt mist in the air flow will be absorbed by the wet curtain plate 402. Immediately afterwards, the air flow passing through the wet curtain plate 402 and the desalting frame 40 will pass through the dehumidifying plate 49, and the dehumidifying plate 49 will absorb and remove the moisture in the air flow. In addition, when the equipment finishes running, the rotating top plate 47 is deflected inward along the fixed shaft 46, so that the resilient plug 48 fixedly connected to the bottom of the rotating top plate 47 will pass through the perforations on the surface of the filter net 400 to clean the impurities accumulated inside the perforations of the filter net 400 outward.

[0088] By the rotation of the motor shaft, the external shaft 43 connected to its outer end will rotate. A number of telescopic rods 404 are fixedly connected to the outside of the external shaft 43. Therefore, when the rotation speed of the motor shaft increases, the centrifugal force of the telescopic rods 404 will become larger, causing the telescopic rods 404 to extend outward. And the elastic ring plate 405 connected to the other end of the telescopic rod 404 will expand outward. The elastic ring plate 405 will keep pressing outward on the hollow frame 406. At this time, the hollow frame 406 will extend into the inside of the air flow pipe 44 from the bottom of the air flow pipe 44, and the opening of the hollow frame 406 will no longer be blocked by the blocking plate 407 and will remain in an open state. Immediately afterwards, the constant temperature element 409 arranged inside the hollow frame 406 will cool the inside of the air flow pipe 44 to cool the air entering the inside of the air flow pipe 44, and indirectly cool the motor 1, the impeller 42 and the motor shaft.

[0089] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concepts and without creative labor, all kinds of transformations made will fall within the scope of protection of the present invention.
