[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] The present invention provides a fan protection device 10 that can be applied to an outdoor air conditioner to protect the fan of the outdoor air conditioner. In the following embodiments, the fan protection device is mainly used in the outdoor air conditioner as an example for description. Other situations where the fan protection device is required to protect the fan can be implemented accordingly.

[0031] See also Figure 1 and Figure 2 The wind turbine protection device 10 includes a protection frame 100, a protection door 200 and a connection assembly 300. The wind turbine can be installed in the protection frame 100, the protection door 200 can be movably installed on the protection frame 100, and the connection assembly 300 is connected between the protection door 200 and the protection frame 100, and is selectively in a first working state or a second working state. The connection assembly 300 in the first working state and the connection assembly 300 in the second working state respectively make the protection door 200 in different position states. For example, Figure 1 As shown, the connection assembly 300 in the first working state can open the protection door 200 so that the fan in the protection frame 100 can better drive the air flow. Figure 2 As shown, the connecting assembly 300 in the second working state can close the protective door 200 to prevent snow or ice from entering the protective frame 100 and adhering to the fan in bad weather, thereby protecting the fan and ensuring that the fan can work normally and prevent damage to the fan, thereby saving excessive resources for clearing snow and ice.

[0032] The protective frame 100 is provided with a fan protection space 101 and an opening 102. The fan protection space 101 can accommodate a fan, and the opening 102 is connected to the fan protection space 101. The protective frame 100 may include a bracket 110 and a base plate 120. The bracket 110 may be connected to the base plate 120, for example, the bracket 110 may be welded to the base plate 120, or for another example, the bracket 110 may be screwed to the base plate 120. The bracket 110 cooperates with the base plate 120 to form the fan protection space 101. The opening 102 is provided on the bracket 110, and the opening 102 is opposite to the base plate 120. In this embodiment, in order to facilitate air flow, the opening 102 may be provided at the top of the bracket 110, which is also conducive to the protective door 200 to protect the fan.

[0033] The bracket 110 can be roughly a rectangular or cube-shaped frame, so that the wind turbine protection device 10 is more compact and takes up less space. The bracket 110 may include a first side frame 111, a second side frame 112 and a third side frame 113. The first side frame 111 and the second side frame 112 may be located on opposite sides of the protection frame 100, and the third side frame 113 is connected between the first side frame 111 and the second side frame 112, and is spaced apart and arranged relative to the bottom plate 120. The first side frame 111, the second side frame 112 and the third side frame enclose an opening 102. In this way, the bracket 110 composed of the first side frame 111, the second side frame 112 and the third side frame 113 cooperates with the bottom plate 120, so that the protection frame 100 has better stability, thereby making the wind turbine protection device 10 more secure and less prone to damage. In addition, ventilation holes 103 may be provided on the surrounding sides of the protective frame 100. For example, the first side frame 111 or the second side frame 112 may be provided with ventilation holes 103, so that the fan 700 can simultaneously drive air in and out of the fan protection space 101 through the opening 102 and the ventilation holes 103, thereby facilitating the fan 700 to quickly drive air to dissipate heat. At the same time, it is also conducive to forming a larger fan protection space 101, so that multiple fans can be installed in the protective frame 100, which is beneficial to the heat dissipation of the air conditioner outdoor unit.

[0034] The protective door 200 is movably connected to the protective frame 100 and is located on one side of the opening 102. The protective door 200 can be hinged to the bracket 110 or connected by a latch, so that the protective door 200 can be movably connected to the protective frame 100. The protective door 200 can have a first position and a second position relative to the protective frame 100. In the first position, the protective door 200 can open the opening 102 (a state in which the opening 102 can be fully opened). For example, the connecting assembly 300, in the first working state, supports the protective door 200 in the first position, so that the protective door 200 can open the opening 102. In the second position, the protective door 200 closes the opening 102 (a state in which the opening 102 is fully closed). For example, the connecting assembly 300, in the second working state, fixes the protective door 200 in the second position, so that the protective door 200 can close the opening 102. In addition, to facilitate understanding of the position of the protective door 200 relative to the protective frame 100, only two positions of the protective door 200 are listed above. The protective door 200 may also have other position states. For example, the position where the protective door 200 partially opens the opening 102 is considered as the first position where the opening 102 is open. For another example, the position where the protective door 200 is about to completely close the opening 102 is considered as the second position where the opening 102 is closed.

[0035] The protective door 200 may include a first protective door panel 210 and a second protective door panel 220. The first protective door panel 210 and the second protective door panel 220 may be roughly arranged in the shape of a rectangular or square plate, so that the protective door 200 can be adapted to the bracket 110 of the protective frame 100, thereby facilitating the opening and closing of the opening 102.

[0036] The first protective door panel 210 is movably connected to the first side frame 111. For example, the first protective door panel 210 can be hinged to the first side frame 111. In another example, the first protective door panel 210 can be connected to the first side frame 111 via a latch, so that the first protective door panel 210 can rotate relative to the first side frame 111. In this way, the first protective door panel 210 can cooperate with the second protective door panel 220 to open or close the opening 102.

[0037] The second protective door panel 220 is movably connected to the second side frame 112. For example, the second protective door panel 220 can be hinged to the second side frame 112. In another example, the second protective door panel 220 can be connected to the second side frame 112 via a latch, so that the second protective door panel 220 can rotate relative to the second side frame 112. In this way, the second protective door panel 220 can cooperate with the first protective door panel 210 to open or close the opening 102.

[0038] When the protective door 200 is in the first position, Figure 1As shown, the width of the first protective door panel 210 extends along the height of the protective frame 100, while the width of the second protective door panel 220 extends along the height of the protective frame 100. The first protective door panel 210 and the second protective door panel 220 are opposite and spaced apart from each other. Specifically, the first side portion 211 is connected to the first side frame 111 and the connecting assembly 300 and is opposite the third side portion 221. The second side portion 212 is opposite and spaced apart from the fourth side portion 222, and the third side portion 221 is also connected to the second side frame 112. The connecting assembly 300 is positioned between the first protective door panel 210 and the third side frame 113, and between the second protective door panel 220 and the third side frame 113. The connecting assembly 300 supports the first and second protective door panels 210 and 220, ensuring that the first and second protective door panels 210 and 220 are opposite and spaced apart from each other. This allows the protective door 200 to open the opening 102, thereby enabling the fan within the protective frame 100 to better drive air flow.

[0039] When the protective door 200 is in the second position, Figure 2 As shown, the first protective door panel 210 and the second protective door panel 220 are both in contact with the third side frame 113. The first protective door panel 210 and the second protective door panel 220 cover the top of the third side frame 113. That is, the first side portion 211 is connected to the first side frame 111, the second side portion 212 is in contact with the third side frame 113, the third side portion 221 is connected to the second side frame 112, the fourth side portion 222 is in contact with the third side frame 113, and the third side portion 221 is opposite to the fourth side portion 222. The connecting assembly 300 fixes the first protective door panel 210 and the second protective door panel 220 so that the first protective door panel 210 and the second protective door panel 220 cover the top of the third side frame 113, thereby allowing the protective door 200 to close the opening 102, preventing snow or ice from entering the protective frame 100 and adhering to the fan in bad weather, so that the fan is protected, thereby ensuring that the fan can work normally and preventing the fan from being damaged.

[0040] Furthermore, when the protective door 200 is in the second position, the side of the first protective door plate 210 facing away from the protective frame 100 has a first slope 213, and the side of the first slope 213 facing the second protective door plate 220 is higher than the side of the first slope 213 facing the first frame. In this way, when it is snowing or hail outside, the side of the first protective door panel 210 facing away from the protective frame 100 can effectively prevent snow and ice from entering the fan protection space 101 from the opening 102. In addition, since the side of the first inclined surface 213 facing the second protective door panel 220 is higher than the side of the first inclined surface 213 facing the first side frame 111, the friction force between the snow or ice attached to the first inclined surface 213 and the first inclined surface 213 cannot overcome its own gravity. Therefore, the snow or ice attached to the first inclined surface 213 can easily slide from the side of the first inclined surface 213 facing the second protective door panel 220 to the side of the first inclined surface 213 facing the first side frame 111, so that the snow and ice attached to the first inclined surface 213 can automatically fall off, avoiding excessive snow or ice on the first inclined surface 213 from crushing the first protective door panel 210, and also avoiding wasting resources in dealing with the snow or ice on the first inclined surface 213. Of course, in addition to allowing accumulated snow or ice to fall off automatically, the first inclined surface 213 can also allow other debris attached to the first inclined surface 213 to fall off.

[0041] Similarly, the second protective door plate 220 has a second inclined surface 223 on the side facing away from the protective frame 100 , and the side of the second inclined surface 223 facing the first protective door plate 210 is higher than the side of the second inclined surface 223 facing the second frame. In this way, when it is snowing or hail outside, the side of the second protective door panel 220 facing away from the protective frame 100 can effectively prevent snow and ice from entering the fan protection space 101 from the opening 102, and because the side of the second inclined surface 223 facing the first protective door panel 210 is higher than the side of the second inclined surface 223 facing the second side frame 112, the friction force between the snow or ice attached to the second inclined surface 223 and the second inclined surface 223 cannot overcome its own gravity. Therefore, the snow or ice attached to the second inclined surface 223 can easily slide from the side of the second inclined surface 223 facing the first protective door panel 210 to the side of the second inclined surface 223 facing the second side frame 112, so that the snow and ice attached to the second inclined surface 223 can automatically fall off, avoiding excessive snow or ice on the second inclined surface 223 from crushing the second protective door panel 220, and also avoiding wasting resources in dealing with the snow or ice on the second inclined surface 223. Of course, in addition to allowing accumulated snow or ice to fall off automatically, the second slope 223 can also allow other debris attached to the second slope 223 to fall off.

[0042] See also Figure 2 and Figure 3The first protective door panel 210 may have a first side portion 211 and a second side portion 212. The first side portion 211 may be connected to the first side frame 111, and the second side portion 212 is opposite the second protective door panel 220. The protective door 200 may also include a first blocking door strip 230. The first blocking door strip 230 is located on the second side portion 212, thereby preventing water on the side of the first protective door panel 210 facing away from the protective frame 100 from flowing back into the opening 102. Of course, the first blocking door strip 230 may be a protrusion or a convex strip, etc. The first blocking door strip 230 may extend along the length of the first protective door panel 210, thereby effectively preventing water on the side of the first protective door panel 210 facing away from the protective frame 100 from flowing back into the opening 102.

[0043] The second protective door panel 220 may have a third side portion 221 and a fourth side portion 222. The third side portion 221 is connected to the second side frame 112 and may be opposite to the fourth side portion 222. The protective door 200 may also include a second blocking strip 240, located on the fourth side portion 222, thereby preventing water on the side of the second protective door panel 220 facing away from the protective frame 100 from flowing back into the opening 102. The second blocking strip 240 may be a bump or a ridge, and may extend along the length of the second protective door panel 220, thereby effectively preventing water on the side of the second protective door panel 220 facing away from the protective frame 100 from flowing back into the opening 102.

[0044] Please refer again Figure 1 The connecting component 300 can be connected between the first protective door plate 210 and the protective frame 100, and between the second protective door plate 220 and the protective frame 100, so as to facilitate the connecting component 300 to support the protective door 200 to open the opening 102 or fix the protective door 200 to close the opening 102.

[0045] The connecting assembly 300 may include a first connecting member 310 and a second connecting member 320. The first connecting member 310 may be connected between the first protective door panel 210 and the protective frame 100. For example, the first connecting member 310 may be connected between the first side portion 211 and the third side frame 113. The first connecting member 310 may be a cylinder or a telescopic rod, etc., so that the first connecting member 310 can support the first protective door panel 210 to partially open the opening 102 or fix the first protective door panel 210 to partially close the opening 102. In addition, the first connecting member 310 may be connected to the first protective door panel 210 and the protective frame 100 via a hinge or a latch, so that the first connecting member 310 is rotatably connected relative to the first protective door panel 210 and the protective frame 100, thereby facilitating the switching of the protective door 200 between the first position and the second position.

[0046] The second connecting member 320 can be connected between the second protective door panel 220 and the protective frame 100. For example, the second connecting member 320 can be connected between the third side portion 221 and the third side frame 113. The second connecting member 320 can be a cylinder or a telescopic rod, etc., so that the second connecting member 320 can support the second protective door panel 220 to partially open the opening 102 or fix the second protective door panel 220 to partially close the opening 102. In addition, the second connecting member 320 can be connected to the second protective door panel 220 and the protective frame 100 via a hinge or a latch, so that the second connecting member 320 is rotatably connected relative to the second protective door panel 220 and the protective frame 100, thereby facilitating the switching of the protective door 200 between the first position and the second position.

[0047] When the connecting assembly 300 is in the first working state, the protective door 200 is in the first position. That is, the first connecting member 310 and the second connecting member 320 are in the extended state, allowing the first connecting member 310 to support the first protective door panel 210 in the first position, and the second connecting member 320 to support the second protective door panel 220 in the second position. This allows the first protective door panel 210 and the second protective door panel 220 to be positioned opposite and spaced apart, thereby allowing the protective door 200 to be opened.

[0048] When the connecting assembly 300 is in the second working state, the protective door 200 is in the second position. That is, the first connecting member 310 and the second connecting member 320 are in the retracted state, allowing the second connecting member 320 to fix the second protective door panel 220 in the second position. The second connecting member 320 can also fix the second protective door panel 220 in the second position, so that the first protective door panel 210 and the second protective door panel 220 are located above the third side frame 113, thereby allowing the protective door 200 to close the opening.

[0049] See also Figures 4 to 6 In some embodiments, the wind turbine protection device 10 further includes a wind turbine mounting frame 400, wherein a mounting cavity 401 is formed in the wind turbine mounting frame 400, and the wind turbine can be mounted in the mounting cavity 401. The wind turbine mounting frame 400 can be used for mounting the wind turbine, facilitates the connection between the wind turbine and the protection frame 100, and improves the stability and firmness of the wind turbine installed in the protection frame 100. The wind turbine mounting frame 400 can be horizontally mounted in the protection frame 100, such as Figure 2 and Figure 4 As shown, for example, the fan mounting frame 400 can be mounted on the bottom plate 120, and the fan mounting frame 400 is opposite to the opening 102, so as to facilitate the fan to discharge hot air upward from the opening 102. In other embodiments, such as Figure 5 To make the diagram concise, Figure 5Only a partial structure of the wind turbine protection device 10 is shown. The wind turbine mounting frame 400 can be vertically installed in the protection frame 100. For example, the wind turbine mounting frame 400 can be installed on the first side frame 111, so as to facilitate the air intake and air discharge of the wind turbine 700.

[0050] In some embodiments, the wind turbine protection device 10 further includes a control device 500. The control device 500 may include a CPU, a memory, an input component, an output component, a power supply, and a programmer, etc., to achieve automatic control of the wind turbine protection device 10. For example, the control device 500 may be electrically connected to the connecting component 300 to control the connecting component 300 to selectively be in the first working state or the second working state. For example, the control device 500 may be electrically connected to the first connecting component 300 and the second connecting component 300 to control the extension and contraction of the first connecting member 310 and the second connecting member 320, so that the first connecting member 310 can support or fix the first protective door panel 210, and the second connecting member 320 can support or fix the second protective door panel 220, thereby improving the intelligence level of the wind turbine protection device 10.

[0051] In some embodiments, the wind turbine guard 10 further includes a temperature sensor 600 capable of detecting the external temperature. The temperature sensor 600 is electrically connected to the control device 500, and both the temperature sensor 600 and the control device 500 are electrically connected to the connection assembly 300. In this way, the wind turbine guard 10 can detect changes in the external temperature, allowing the opening 102 to be opened or closed according to different temperature environments, further enhancing the intelligence of the wind turbine guard 10. For example, when the temperature sensor 600 detects that the outdoor temperature is low and there is a possibility of snow or hail, the control device 500 can control the connection component 300 to extend and retract according to the detection result of the temperature sensor 600, so that the connection component 300 can fix the protective door 200, thereby allowing the protective door 200 to close the opening 102; when the temperature sensor 600 detects that the outdoor ambient temperature is high, the control device 500 can control the connection component 300 to extend and retract according to the detection result of the temperature sensor 600, so that the connection component 300 can support the protective door 200, thereby allowing the protective door 200 to open the opening 102, thereby facilitating the fan to drive air heat dissipation.

[0052] See also Figure 7The present invention also provides an air conditioning outdoor unit 20, which can be used in a data center computer room to dissipate heat from cabinet equipment. The air conditioning outdoor unit 20 can include a fan 700 and a fan protection device 10. The fan 700 can be installed in the protective space of the fan protection device 10 to protect the fan 700. The specific structure of the fan protection device 10 is similar to the above-mentioned embodiments. Since the air conditioning outdoor unit 20 adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be detailed here.

[0053] See also Figure 8 The present invention provides a protection and control method for a fan. The protection and control method for a fan can be applied to a fan protection device. The specific structure of the fan protection device 10 refers to the above embodiment. Since the protection and control method of the fan adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The protection and control method for the fan of the present invention can control the fan protection device 10 to protect the fan 700, so as to improve the automation and intelligence level of the air-conditioning outdoor unit 20 and save the cost of protecting the fan 700.

[0054] In some embodiments, the wind turbine protection control method includes:

[0055] Get the outdoor ambient temperature;

[0056] If the outdoor ambient temperature is greater than the temperature threshold, the connection assembly 300 is controlled to be in the first working state to open the protective door 200 to open the opening 102;

[0057] If the outdoor ambient temperature is less than or equal to the temperature threshold, the control connection component 300 is in the second working state to close the protective door 200 to seal the opening 102.

[0058] The outdoor ambient temperature may be obtained, for example, by using a temperature sensor 600 to collect the data.

[0059] The fan protection control method is based on a comparison between the outdoor ambient temperature and a temperature threshold. When the outdoor ambient temperature is greater than the temperature threshold, the connection assembly 300 switches to a first operating state. When the outdoor ambient temperature is less than or equal to the temperature threshold, the connection assembly 300 switches to a second operating state. In other words, the operating state of the connection assembly 300 can be switched based on the outdoor ambient temperature, thereby causing the protective door 200 to open or close the opening 102.

[0060] In addition, the temperature threshold can be set according to the application of the air conditioner outdoor unit 20. When the outdoor ambient temperature is greater than the temperature threshold, the connecting assembly 300 is in the first working state, the first connecting member 310 is in the extended state, so that the first connecting member 310 supports the first protective door panel 210, and the second connecting member 320 is in the extended state, so that the second connecting member 320 supports the second protective door panel 220, thereby allowing the protective door 200 to open the opening 102, which is conducive to the fan 700 driving air for heat dissipation. When the outdoor ambient temperature is less than or equal to the temperature threshold, there may be extreme weather such as snow or hail outdoors, and the connecting component 300 is in the second working state, and the first connecting member 310 and the second connecting member 320 are in a retracted state, so that the first connecting member 310 fixes the first protective door panel 210, and the second connecting member 320 fixes the second protective door panel 220, so that the first protective door panel 210 and the second protective door panel 220 are abutted, thereby allowing the protective door 200 to close the opening 102, which is beneficial for the protective door 200 to block snow and ice from entering the fan protection space 101 from the opening 102, ensuring that the fan 700 can work normally.
