[0041] The device can greatly improve the dust removal efficiency of the communication equipment fan, does not need to carry the fan, can complete dust removal in front of the equipment rack in the communication room, and also avoids that carrying the fan may cause damage to the fan and injury to the personnel.

[0042] In some preferred embodiments, the specific structure of the air blowing assembly 3 is described in detail.

[0043] The air blowing assembly 3 comprises:

[0044] The guide rail structure 300 is installed on the inner top wall of the sealed space, and a plurality of hangers 301 are movably arranged at the bottom of the guide rail structure 300, and an air gun 302 is arranged on each hanger 301;

[0045] The air compressor 304 is arranged inside or outside the box 1 and is connected with the air gun 302 through the air pipe 303 and the conversion subhead 308;

[0046] The power module 305 is connected with the air compressor 304 and is installed on the box 1.

[0047] The power module 305 and the air compressor 304 provide the air source, and then the air gun 302 on each hanger 301 generates high-pressure gas through the air pipe 303 and the conversion subhead 308, so as to realize dust removal of the communication equipment fan at multiple points and improve the dust removal efficiency. In addition, the power module 305 is located at the bottom of the back of the device, which can be a power interface or a battery pack with stored electric energy, and the battery pack has a charging interface.

[0048] Reference Figure 3 and Figure 4 Further, since the sizes of the communication equipment fans are different, it is necessary to adjust the positions of the air guns 302, that is, to adjust them arbitrarily, and the specific adjustment is as follows:

[0049] The guide rail structure 300 comprises a mounting plate 3001, the bottom of the mounting plate 3001 is provided with a first guide rail 3002 and a second guide rail 3003, the bottom of each of the first guide rail 3002 and the second guide rail 3003 is provided with a T-shaped slide, and the first guide rail 3002 and the second guide rail 3003 are longitudinally and transversely arranged and are in communication with each other at the intersection.

The air spray gun 302 can replace the spray nozzles of different sizes to adjust the size of the air outlet area to meet the dust removal requirements in different situations.

[0051] Through the above arrangement, the position of the boom 301 can be adjusted to facilitate dust removal of different communication equipment fans. The position can be manually adjusted to align different parts of the fan to be dusted, and the air spray gun 302 sprays high-pressure air to blow off the dust on the fan.

[0052] The sliding block 306 includes a buckle block 3061, the bottom of the buckle block 3061 is fixedly connected with the top of the boom 301, and the bottom of the buckle block 3061 is in contact with the first ball 3062 on the inner wall of the T-shaped slide. Such a ball structure reduces friction and facilitates movement while preventing up and down movement during air jet. Of course, the sliding block 306 can be a T-shaped slide.

[0053] Furthermore, the boom 301 also moves left and right during air jet, so the boom 301 is provided with a locking member 307 below the guide rail structure 300, which is used to abut or move away from the bottom surface of the guide rail structure 300. Thus, the position of the boom 301 is locked to ensure the dust removal effect. The locking member 307 includes a horizontal support 3071 fixedly connected with the boom 301, a vertical screw 3072 threadedly connected with the horizontal support 3071, and a rubber pad 3073 provided on the top of the vertical screw 3072. Of course, other locking forms such as a locking pin and a telescopic form are not excluded.

[0054] In some preferred embodiments, the hollow placement rack 2 can be a plate with through holes; however, in order to allow the gas and dust to quickly fall without being blocked, the following arrangement is provided:

[0055] Reference Figure 5 and Figure 6 The hollow placement rack 2 includes a plurality of cylindrical cross bars 201 and two horizontally spaced guide rails 200, and the guide rail 200 is provided with a T-shaped slide extending along the length direction thereof; the two ends of the cylindrical cross bar 201 are connected with the corresponding T-shaped slide through a sliding structure 202. The sliding structure 202 includes a baffle fixedly connected with the end of the cylindrical cross bar 201, and a second ball is arranged between the baffle and the inner wall of the T-shaped slide.

[0056] The above arrangement realizes maximum hollowing while also realizing supporting, and in addition, the sliding structure 202 allows the cylindrical cross bar 201 to move smoothly, and the spacing can be manually adjusted to place fans of different sizes to be dusted by adjusting the spacing of the cylindrical cross bars 201.

[0057] In some preferred embodiments, the exhaust assembly 4 comprises an exhaust pipe 400, the inside of which is provided with a motor fan 401;

[0058] In the axial direction of the exhaust pipe 400, the distance between the motor fan 401 and the sealed space is greater than the distance between the filter 5 and the sealed space. Exhaust is achieved without polluting the environment. The air end of the exhaust pipe 400 is provided with a protective net in a grid shape to prevent the blades of the motor fan 401 from being accidentally touched.

[0059] The opening and closing hatch 7 is provided with an observation glass; the opening and closing hatch 7 is used for the placement and removal of the fan to be dedusted; the bottom of the box body 1 is provided with universal wheels 6. The observation glass facilitates the observation of the dust removal effect and progress, and the universal wheels 6 at the bottom can make the device flexible in moving position.

[0060] Beneficial effects:

[0061] The device can greatly improve the dust removal efficiency of the fan of the communication equipment, and can complete the dust removal in front of the equipment rack in the communication room without carrying the fan, thereby avoiding the damage of the fan and the injury of the personnel caused by carrying the fan. The device adopts a closed design, the dust removal process does not cause pollution to the external environment, and the device is powered by a rechargeable battery, so that the device does not need to be connected to a power source during work. In combination with the universal wheels at the bottom of the device, the device can be flexibly moved in position.

[0062] The position of the air spray gun 302 is freely adjusted, and a locking member 307 is designed to avoid the sliding of the air spray gun 302 caused by airflow during use, so that accurate dust removal can be achieved at different positions. The air spray gun 302 nozzle can be replaced with nozzles of different sizes and shapes to adjust the size of the air outlet area and meet the dust removal needs in different situations; the hollow placement rack 2 is designed with a spacing-adjustable cylindrical cross bar 201, which can adapt to different fan sizes.
