Description

Technical Field

[0001] This invention relates to the field of communication equipment room technology, and more specifically, to a dustproof device and a communication equipment room having the same. Background Technology

[0002] With the rapid development of the mobile Internet era, telecommunications operators have built a large number of base stations to meet market demand. As the carrier of base stations, communication equipment rooms are a necessary protection measure for communication base stations and a primary condition for base station construction. They have advantages such as strong adaptability, rapid deployment capability, energy saving and high efficiency.

[0003] In related technologies, communication equipment rooms are installed outdoors. In summer, when the temperature is high, in order to prevent the high temperature generated inside the equipment room from affecting the operation of the internal electrical appliances, the communication equipment room is equipped with a heat dissipation device. The heat dissipation device has an air inlet, an air outlet, and a cooling fan. The cooling fan is used to achieve air convection and remove the high-heat gas to achieve the purpose of cooling.

[0004] However, in related technologies, in order to prevent foreign objects such as leaves, plastic bags or sand from entering the communication equipment room, dust screens are installed at the air inlets of the heat dissipation devices. However, under the action of the fan, negative pressure is generated at the air inlet, which can cause foreign objects to adhere to the surface of the dust screen and cause blockage, affecting the air intake efficiency and thus affecting the heat dissipation effect. Summary of the Invention

[0005] This invention provides a dustproof device and a communication equipment room having the same, to solve the problem in related technologies where dustproof netting blockage affects the heat dissipation effect of the communication equipment room.

[0006] According to one aspect of the present invention, a dustproof device is provided, comprising: a dustproof net; a sliding member movably disposed inside the dustproof net; a cleaning member movably disposed outside the dustproof net, wherein a first cleaning structure is provided between the cleaning member and the dustproof net; and a driving member drivenly connected to the sliding member to drive the sliding member to move, wherein the sliding member and the cleaning member are magnetically engaged to drive the cleaning member to move in the same direction as the sliding member.

[0008] Furthermore, the second cleaning structure includes: a protrusion disposed on the inner surface of the dustproof net; and an elastic impact member disposed retractably in the inward and outward directions on the side of the sliding member facing the dustproof net. The elastic impact member has a compressed state that abuts against the protrusion and an impact state that is separated from the protrusion. When the elastic impact member switches from the compressed state to the impact state, the elastic impact member extends outward relative to the sliding member and impacts the dustproof net.

[0009] Furthermore, the elastic impact member includes: an impact protrusion movably disposed on the sliding member in the inward and outward directions; when the elastic impact member is in a compressed state, the impact protrusion abuts against the protrusion; when the elastic impact member switches from a compressed state to an impact state, the impact protrusion extends outward relative to the sliding member and impacts the dustproof net; and an elastic member, the two ends of which are respectively connected to the impact protrusion and the sliding member to apply a restoring force that extends outward relative to the sliding member to the impact protrusion.

[0010] Furthermore, the sliding member has an air cavity, and the elastic impact member also includes a partition plate disposed within the air cavity. The partition plate is slidably disposed within the air cavity in the inward and outward directions and divides the air cavity into a first cavity and a second cavity. The first cavity is located on the side of the second cavity away from the dustproof net. The impact protrusion is disposed on the side of the partition plate facing the dustproof net. The elastic member is disposed within the first cavity, and both ends of the elastic member are connected to the partition plate and the sliding member, respectively. The end of the impact protrusion facing the dustproof net protrudes through the sliding member. The second cleaning structure also includes a cleaning air pipe disposed on the side wall of the sliding member. The cleaning air pipe includes a first pipe section. The first end of the first pipe section is connected to the first cavity, and the second end of the first pipe section extends to the inner surface of the dustproof net. A pneumatic pin is disposed at the second end of the first pipe section.

[0011] Furthermore, the pneumatic inserter includes a sliding seat, an elastic inserter, and a spring. The sliding seat is slidably sleeved on the second end of the first tube segment and sealed to the second end of the first tube segment. The elastic inserter is disposed on the side of the sliding seat facing the dustproof net. The two ends of the spring are respectively connected to the sliding seat and the first tube segment to apply a restoring force away from the dustproof net to the sliding seat.

[0012] Furthermore, the cleaning trachea also includes a second section, the first end of which is connected to the first cavity, and the second end of which extends to the inner surface of the dustproof net and is provided with a nozzle; and / or, the second cleaning structure also includes an elastic membrane disposed in the cleaning trachea, the elastic membrane having a constriction orifice, the constriction orifice having a closed state and an open state, and when the air pressure in the cleaning trachea is greater than or equal to the opening threshold, the constriction orifice switches from the closed state to the open state.

[0013] Furthermore, the dustproof device also includes a collection frame, which is movably disposed below the dustproof net in the inward and outward directions. The collection frame has an upward-facing dust collection port. The cleaning component and the sliding component move relative to the dustproof net in the up-down direction, and the cleaning component can move into the collection frame.

[0014] Furthermore, the cleaning component includes a scraper and a vibrating component. The scraper and the sliding component are movably disposed on the outside of the dustproof net in the same direction. The side wall of the scraper facing the dustproof net forms a first cleaning structure. The scraper and the sliding component are magnetically engaged. The scraper has a cavity, and the vibrating component is disposed in the cavity. When the scraper leaves the collection frame, the vibrating component impacts the inner wall of the cavity.

[0015] Furthermore, the vibrating element includes an elastic rope and a magnetic ball. The elastic rope is disposed in the cavity and extends laterally. Both ends of the elastic rope are connected to the scraper. The magnetic ball is disposed in the middle of the elastic rope. A magnetic suction device is provided on the collection frame. When the scraper is located in the collection frame, the magnetic suction device and the magnetic ball magnetically cooperate to make the elastic rope in a stretched state. And / or, an anti-slip pad is provided on the lower surface of the collection frame.

[0016] Furthermore, the dustproof device also includes a mounting frame and a moisture-absorbing plate mounted on the mounting frame, both of which are located inside the dustproof net.

[0017] Furthermore, the mounting frame includes: a frame body located inside the dustproof net; an arched spring piece, the first end of which is connected to the frame body, the middle of which protrudes upward, and the lower end of the moisture-absorbing plate connected to the middle of the arched spring piece; and an alarm switch located on the frame body and below the second end of the arched spring piece. The moisture-absorbing plate has a usage state and a threshold state. When the moisture-absorbing plate is in the threshold state, it can trigger the alarm switch.

[0018] Furthermore, the sliding component includes a sliding plate and an active magnetic block disposed on the sliding plate, and a driven magnetic block is disposed on the cleaning component. The magnetism of the end of the active magnetic block facing the dustproof net is opposite to the magnetism of the end of the driven magnetic block facing the dustproof net. The dustproof device also includes a mounting frame surrounding the outside of the dustproof net. A guide groove is disposed on the inner surface of the mounting frame. The guide groove extends vertically, and the active magnetic block is movably disposed in the guide groove along the extension direction of the guide groove. The driving component includes a motor and a threaded transmission rod. The motor is disposed on the mounting frame, and the output shaft of the motor is connected to the threaded transmission rod to drive the threaded transmission rod to rotate around its vertical axis. The threaded transmission rod passes through the sliding component and is threadedly engaged with the sliding component. The holes of the dustproof net gradually slope upward in the direction from the outside to the inside.

[0020] According to the technical solution of this invention, the dustproof device includes a dustproof net, a sliding member, a cleaning member, and a driving member. The driving member drives the sliding member to move relative to the dustproof net. Due to the magnetic attraction between the sliding member and the cleaning member, the sliding member drives the cleaning member to move in the same direction relative to the dustproof net. Furthermore, since a first cleaning structure is provided between the cleaning member and the dustproof net, the outer surface of the dustproof net can be cleaned by the first cleaning structure during the movement of the cleaning member relative to the dustproof net. This prevents foreign objects such as sand particles, plastic bags, and leaves from adhering to the outer surface of the dustproof net, thus avoiding affecting the heat dissipation effect of the communication equipment room. This effectively protects the electrical equipment in the communication equipment room, prevents the electrical equipment from aging excessively at high temperatures, and thereby improves the service life of the electrical equipment.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 7As shown, this embodiment of the invention provides a dustproof device, which includes a dustproof net 10, a sliding member 20, a cleaning member 30, and a driving member 40. The sliding member 20 is movably disposed on the inner side of the dustproof net 10, and the cleaning member 30 is movably disposed on the outer side of the dustproof net 10. A first cleaning structure is provided between the cleaning member 30 and the dustproof net 10. The driving member 40 is drivenly connected to the sliding member 20 to drive the sliding member 20 to move. The sliding member 20 and the cleaning member 30 are magnetically attracted to drive the cleaning member 30 and the sliding member 20 to move in the same direction.

[0042] Using the dustproof device provided in this embodiment, the sliding member 20 is driven by the driving member 40 to move relative to the dustproof net 10. Since the sliding member 20 and the cleaning member 30 are magnetically attracted, the sliding member 20 drives the cleaning member 30 to move in the same direction relative to the dustproof net 10. Furthermore, since a first cleaning structure is provided between the cleaning member 30 and the dustproof net 10, the outer surface of the dustproof net 10 can be cleaned by the first cleaning structure during the movement of the cleaning member 30 relative to the dustproof net 10. This prevents foreign objects such as sand particles, plastic bags, and leaves from adhering to the outer surface of the dustproof net 10, thus avoiding affecting the heat dissipation effect of the communication equipment room. This effectively protects the electrical equipment in the communication equipment room, prevents the electrical equipment from aging excessively under high temperature, and thereby improves the service life of the electrical equipment.

[0043] like Figure 3 and Figure 4 As shown, the dustproof device also includes a second cleaning structure 50 disposed between the sliding member 20 and the dustproof net 10. By employing the second cleaning structure 50, during the movement of the sliding member 20 relative to the dustproof net 10, the dustproof net 10 can be cleaned from the inside using the second cleaning structure 50, thereby improving the cleaning effect on the dustproof net 10.

[0044] like Figure 3As shown, the second cleaning structure 50 includes a protrusion 51 and an elastic impact member 52. The protrusion 51 is disposed on the inner surface of the dustproof net 10. The elastic impact member 52 is telescopically disposed on the side of the sliding member 20 facing the dustproof net 10 in the inward and outward directions. The elastic impact member 52 has a compressed state that abuts against the protrusion 51 and an impact state that is separated from the protrusion 51. When the elastic impact member 52 switches from the compressed state to the impact state, the elastic impact member 52 extends outward relative to the sliding member 20 and impacts the dustproof net 10. During the movement of the sliding member 20 relative to the dustproof net 10, when the elastic impact member 52 moves with the sliding member 20 to the protrusion 51, the protrusion 51 abuts against the elastic impact member 52 and compresses the elastic impact member 52 away from the dustproof net 10 in the inward and outward directions. When the elastic impact member 52 moves with the sliding member 20 to the point of separation from the protrusion 51, the elastic impact member 52 switches from the compressed state to the impact state. The elastic impact member 52 extends outward relative to the sliding member 20 and impacts the dustproof net 10. The vibration generated can shake off the impurities on the dustproof net 10, preventing impurities from being stored in the holes of the dustproof net 10, which the cleaning member 30 cannot scrape off.

[0045] like Figure 3 As shown, the elastic impact member 52 includes an impact protrusion 521 and an elastic member 522. The impact protrusion 521 is movably disposed on the sliding member 20 in the inward and outward directions. When the elastic impact member 52 is in a compressed state, the impact protrusion 521 and the protrusion 51 abut against each other. When the elastic impact member 52 switches from the compressed state to the impact state, the impact protrusion 521 extends outward relative to the sliding member 20 and impacts the dustproof net 10. The two ends of the elastic member 522 are respectively connected to the impact protrusion 521 and the sliding member 20 to apply a restoring force that extends outward relative to the sliding member 20 to the impact protrusion 521. When the elastic impact member 52 moves with the sliding member 20 to the protrusion 51, the protrusion 51 abuts against the impact protrusion 521 and drives the impact protrusion 521 to move away from the dustproof net 10 along the inner and outer direction box, and compresses the elastic member 522. When the elastic impact member 52 moves with the sliding member 20 to the point where it separates from the protrusion 51, the elastic member 522 applies a restoring force to the impact protrusion 521 relative to the sliding member 20, so that the elastic member 522 extends outward relative to the sliding member 20 and impacts the dustproof net 10.

[0046] like Figure 3As shown, the sliding member 20 has an air cavity 21, and the elastic impact member 52 further includes a partition plate 523 disposed within the air cavity 21. The partition plate 523 is slidably disposed within the air cavity 21 in the inward and outward directions and divides the air cavity 21 into a first cavity 211 and a second cavity 212. The first cavity 211 is located on the side of the second cavity 212 facing away from the dustproof net 10. The impact protrusion 521 is disposed on the side of the partition plate 523 facing the dustproof net 10. The elastic member 522 is disposed within the first cavity 211. Both ends of 522 are connected to the partition plate 523 and the sliding member 20 respectively. The end of the impact protrusion 521 facing the dustproof net 10 passes through the sliding member 20. The second cleaning structure 50 also includes a cleaning air pipe 53 provided on the side wall of the sliding member 20. The cleaning air pipe 53 includes a first pipe section 531. The first end of the first pipe section 531 is connected to the first cavity 211. The second end of the first pipe section 531 extends to the inner surface of the dustproof net 10. A pneumatic pin 5311 is provided at the second end of the first pipe section 531. When the elastic impact member 52 moves with the sliding member 20 to the protrusion 51, the protrusion 51 abuts against the impact protrusion 521 and drives the impact protrusion 521 and the partition plate 523 to move away from the dustproof net 10 along the inner and outer direction box, compressing the first cavity 211, so that the gas in the first cavity 211 enters the cleaning air pipe 53, so that the pneumatic needle 5311 set at the second end of the first pipe section 531 is inserted into the mesh of the dustproof net 10, clearing the mesh of the dustproof net 10, preventing sand and gravel particles from getting stuck in the dustproof net 10, and further improving the cleaning effect of the dustproof net 10.

[0047] like Figure 3 As shown, the pneumatic needle 5311 includes a sliding seat 5312, an elastic needle 5313, and a spring 5314. The sliding seat 5312 is slidably sleeved on the second end of the first tube segment 531 and sealed to the second end of the first tube segment 531. The elastic needle 5313 is disposed on the side of the sliding seat 5312 facing the dustproof net 10. The two ends of the spring 5314 are respectively connected to the sliding seat 5312 and the first tube segment 531 to apply a restoring force away from the dustproof net 10 to the sliding seat 5312. After the gas in the first cavity 211 enters the cleaning air pipe 53, the gas in the first tube segment 531 drives the sliding seat 5312 to move towards the dustproof net 10, so that the elastic needle 5313 is inserted into the mesh of the dustproof net 10, clearing the mesh of the dustproof net 10 and preventing sand and gravel particles from getting stuck in the dustproof net 10, thereby further improving the cleaning effect of the dustproof net 10. The spring 5314 provides the restoring force, and the elastic pin 5313 can prevent the pneumatic pin 5311 from getting stuck in the mesh of the dustproof net 10.

[0048] like Figure 3As shown, the cleaning air pipe 53 also includes a second pipe section 532. The first end of the second pipe section 532 is connected to the first cavity 211, and the second end of the second pipe section 532 extends to the inner surface of the dustproof net 10 and is provided with a nozzle 5321. After the gas in the first cavity 211 enters the cleaning air pipe 53, the gas in the second pipe section 532 is blown towards the dustproof net 10 through the nozzle 5321, further improving the cleaning effect.

[0049] like Figure 4 As shown, the second cleaning structure 50 also includes an elastic membrane 54 disposed within the cleaning air tube 53. The elastic membrane 54 has a constriction orifice 541, which has a closed state and an open state. When the air pressure within the cleaning air tube 53 is greater than or equal to an opening threshold, the constriction orifice 541 switches from the closed state to the open state. The gas can be briefly compressed through the elastic membrane 54, and when the threshold of the elastic membrane 54 is reached, it will be ejected outward, thereby enhancing the cleaning effect of the nozzle 5321 through the resulting impact force.

[0050] like Figure 2 and Figure 5 As shown, the dustproof device also includes a collection frame 60, which is movably disposed below the dustproof net 10 in the inward and outward directions. The collection frame 60 has an upward-facing dust collection port 61. The cleaning member 30 and the sliding member 20 move relative to the dustproof net 10 in the vertical direction, and the cleaning member 30 can move into the collection frame 60. Impurities cleaned from the dustproof net 10 can be collected into the collection frame 60 through the dust collection port 61 and collected through the collection frame 60. Because the height of the collection frame 60 is lower than that of the dustproof net 10, when the cleaning member 30 can move into the collection frame 60, it can compact the impurities in the collection frame 60, preventing the scraped impurities from scattering near the dustproof net 10 and being re-absorbed, and also facilitating cleaning by the staff.

[0051] like Figure 5 and Figure 6 As shown, the cleaning component 30 includes a scraper 31 and a vibrator 32. The scraper 31 and the sliding component 20 are movably disposed on the outside of the dustproof net 10 in the same direction. The side wall of the scraper 31 facing the dustproof net 10 forms a first cleaning structure. The scraper 31 and the sliding component 20 are magnetically attracted to each other. The scraper 31 has a cavity 311, and the vibrator 32 is disposed in the cavity 311. When the scraper 31 leaves the collection frame 60, the vibrator 32 impacts the inner wall of the cavity 311. The sliding component 20 drives the scraper 31 to move in the same direction relative to the dustproof net 10, and uses the side wall of the scraper 31 facing the dustproof net 10 to scrape off the impurities on the dustproof net 10. When the scraper 31 leaves the collection frame 60, the vibrator 32 impacts the inner wall of the cavity 311 to shake off the impurities on the scraper 31.

[0052] like Figure 6As shown, the vibrating element 32 includes an elastic rope 321 and a magnetic ball 322. The elastic rope 321 is disposed in the cavity 311 and extends laterally. Both ends of the elastic rope 321 are connected to the scraper 31. The magnetic ball 322 is disposed in the middle of the elastic rope 321. A magnetic suction element 62 is disposed on the collecting frame 60. When the scraper 31 is located in the collecting frame 60, the magnetic suction element 62 and the magnetic ball 322 magnetically attract each other, so that the elastic rope 321 is in a stretched state. When the scraper 31 leaves the collecting frame 60, the elastic rope 321 is in a stretched state. When the magnetic attraction force applied by the magnetic suction element 62 to the magnetic ball 322 is less than the elastic force applied by the elastic rope 321 to the magnetic ball 322, the elastic rope 321 returns to its initial state, thereby driving the magnetic ball 322 to strike the inner wall of the cavity 311.

[0053] like Figure 2 As shown, the lower surface of the collection frame 60 is provided with an anti-slip pad 63 to increase the friction between the lower surface of the collection frame 60 and the mounting frame 80, and to prevent the collection frame 60 from falling off during the cleaning of the dust net 10.

[0054] like Figure 7 As shown, the dustproof device also includes a mounting frame 71 and a moisture-absorbing plate 72 mounted on the mounting frame 71. Both the mounting frame 71 and the moisture-absorbing plate 72 are located inside the dustproof net 10. In summer rainy weather or when the air is relatively humid, the moisture-absorbing particles in the moisture-absorbing plate 72 absorb the moisture in the air, preventing the electrical appliances in the computer room 91 from being corroded by rainwater and causing short circuits.

[0055] like Figure 7 As shown, the mounting bracket 71 includes a frame 711, an arched spring 712, and an alarm switch 713. The frame 711 is located inside the dustproof net 10. The first end of the arched spring 712 is connected to the frame 711, and the middle part of the arched spring 712 protrudes upward. The lower end of the moisture-absorbing plate 72 is connected to the middle part of the arched spring 712. The alarm switch 713 is set on the frame 711 and located below the second end of the arched spring 712. The moisture-absorbing plate 72 has a use state and a threshold state. When the moisture-absorbing plate 72 is in the threshold state, the moisture-absorbing plate 72 can trigger the alarm switch 713. As the moisture-absorbing particles inside the moisture-absorbing plate 72 absorb more and more moisture, the moisture-absorbing plate 72 becomes increasingly heavy. At this point, the moisture-absorbing plate 72 will press down on the middle of the arched spring 712, causing the free end of the arched spring 712 to extend. When the moisture-absorbing plate 72 reaches its threshold state, it can no longer absorb moisture. At this time, the weight of the moisture-absorbing plate 72 reaches its maximum, and the free end of the arched spring 712 extends to contact the alarm switch 713, triggering the alarm switch 713 and reminding the staff to replace the moisture-absorbing plate 72 in time.

[0056] In this embodiment, the mounting bracket 71 also includes a warning light installed on the bracket body. The warning light is electrically connected to the alarm switch 713. When the alarm switch 713 is triggered, the warning light is powered on and illuminated, so that the staff can promptly detect the problem during inspection and replace the moisture-absorbing plate 72.

[0057] like Figure 5 As shown, the sliding member 20 includes a sliding plate 22 and an active magnetic block 23 disposed on the sliding plate 22. The cleaning member 30 is provided with a driven magnetic block 33. The magnetism of the end of the active magnetic block 23 facing the dustproof net 10 is opposite to the magnetism of the end of the driven magnetic block 33 facing the dustproof net 10. When the sliding plate 22 moves, the sliding plate 22 drives the active magnetic block 23 to move. The active magnetic block 23 applies a magnetic attraction force to the driven magnetic block 33 to drive the driven magnetic block 33 to move synchronously, so that the driven magnetic block 33 drives the cleaning member 30 to clean the outer surface of the dustproof net 10 using the first cleaning structure.

[0058] In this embodiment, the driven magnetic block 33 is provided with a rounded chamfer on the side facing the dustproof net 10 to improve the smoothness of the movement of the active magnetic block 23, prevent the driven magnetic block 33 from getting stuck at the position where the collection frame 60 and the dustproof net 10 meet, and avoid affecting the scraper 31 cleaning the dustproof net 10.

[0059] like Figure 2 As shown, the dustproof device also includes a mounting frame 80 surrounding the outside of the dustproof net 10. A guide groove 81 is provided on the inner surface of the mounting frame 80. The guide groove 81 extends vertically, and the active magnetic block 23 is movably disposed within the guide groove 81 along the extending direction of the guide groove 81. By utilizing the guiding effect of the guide groove 81 on the active magnetic block 23, the reliability of the movement path of the sliding plate 22 relative to the dustproof net 10 is improved.

[0060] like Figure 2 As shown, the driving component 40 includes a motor 41 and a threaded transmission rod 42. The motor 41 is mounted on the mounting frame 80, and its output shaft is connected to the threaded transmission rod 42 to drive the threaded transmission rod 42 to rotate around its vertical axis. The threaded transmission rod 42 passes through the sliding member 20 and is threadedly engaged with it. After the dustproof device has been used for a period of time, the motor 41 is energized, causing its output shaft to drive the threaded transmission rod 42 to rotate forward and backward around its vertical axis. Since the threaded transmission rod 42 passes through the sliding member 20 and is threadedly engaged with it, the forward and reverse rotating threaded transmission rod 42 uses the threaded structure of its threaded engagement with the sliding member 20 to drive the sliding member 20 to move up and down relative to the dustproof net 10.

[0061] like Figure 3 As shown, the holes of the dustproof net 10 gradually slope upwards from the outside to the inside. This prevents impurities cleaned off the dustproof net 10 from falling back into the inside of the dustproof net 10 through the holes, thus improving the dustproof effect of the dustproof device.

[0062] like Figures 1 to 8 As shown, another embodiment of the present invention provides a communication equipment room, which includes an equipment room 91 and a dustproof device. The equipment room 91 has a receiving cavity 911 and an air inlet 912 and an air outlet 913 connected to the receiving cavity 911. A protective net 914 is provided at the air outlet 913. The dustproof device is provided at the air inlet 912. The dustproof device is the dustproof device provided above. The communication equipment room provided in this embodiment can also use the driving component 40 to drive the sliding component 20 to move relative to the dustproof net 10. Since the sliding component 20 and the cleaning component 30 are magnetically attracted to each other, the sliding component 20 drives the cleaning component 30 to move in the same direction relative to the dustproof net 10. Furthermore, since a first cleaning structure is provided between the cleaning component 30 and the dustproof net 10, the outer surface of the dustproof net 10 can be cleaned by the first cleaning structure during the movement of the cleaning component 30 relative to the dustproof net 10. This prevents foreign objects such as sand particles, plastic bags, and leaves from adhering to the outer surface of the dustproof net 10, thus avoiding affecting the heat dissipation effect of the communication equipment room. This effectively protects the electrical equipment in the communication equipment room, prevents the electrical equipment from aging excessively under high temperature, and thus improves the service life of the electrical equipment.

[0063] like Figure 8 As shown, the communication equipment room also includes a cooling fan 93 located at the air outlet 913 and inside the dustproof net 10. The cooling fan 93 quickly exhausts the hot air in the housing 911 through the air outlet 913. When the communication equipment room is operating in summer, the interior of the equipment room 91 will generate high temperatures. At this time, the cooling fan 93 is activated to drive the airflow in the housing 911. In conjunction with the air inlet 912 and the air outlet 913, the hot air in the housing 911 is quickly exhausted through the air outlet 913, while cool outside air is introduced into the housing 911 through the air inlet 912, thereby achieving the purpose of cooling.

[0064] In this embodiment, the equipment room 91 adopts a corrugated plate structure, and reinforcing ribs are provided in the grooves of the corrugated plate to improve the structural strength of the equipment room 91, thereby significantly improving the anti-theft effect of the communication equipment room.

[0065] like Figure 1 As shown, the communication equipment room also includes an openable security door 94 on one side of the equipment room 91, which improves the anti-theft effect of the communication equipment room without affecting the entry and exit of staff in the equipment room 91.

[0066] like Figure 8 As shown, the communication equipment room also includes an infrared sensor 95 installed in the equipment room 91, which further enhances the anti-theft effect of the communication equipment room.

[0067] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0068] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0069] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0070] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0071] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0072] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
