Description

Antenna base station aging test box Technical Field

[0001] The invention belongs to the technical field of antenna base station detection, and in particular relates to an antenna base station aging test box. Background Art

[0002] Existing 5G or 4G antenna base stations are composed of multiple antenna arrays. In mobile communication network engineering design, antenna base stations should be selected based on specific requirements, such as network coverage, traffic distribution, anti-interference requirements, and network service quality. However, any antenna base station generates heat during use, which accelerates its aging and shortens its actual service life. Generally, multiple antenna base stations are distributed throughout a space to form a communication system. If operators fail to predict the service life of antenna base stations within a communication system, the entire communication system can easily be damaged, forcing it to suddenly cease operation. Sudden damage to the antenna base station can even lead to other serious consequences.

[0003] Therefore, there is an urgent need for a test device for measuring the actual life of the antenna base station during use, so as to facilitate operators to predict the service life of the antenna base station and promptly repair the antenna base station of the operating system.

[0004] A Chinese invention patent with publication number CN115913399B discloses an aging test device for an antenna base station, comprising a box and a sealed door. The box includes a test chamber, support columns, an air duct, and an air circulation device. The box is provided with a test chamber, an access port for placing a device under test into the test chamber, a sealed door at the access port, and support columns installed in the test chamber. An air duct is provided between the outer wall of the box and the test chamber, a uniform air outlet is provided at the upper end of the test chamber, and a uniform air inlet is provided on the side wall of the test chamber. An air circulation device is provided at the uniform air outlet, and the air circulation device is used to guide the gas in the test chamber to move upward. The present invention reduces energy consumption by using the self-heating of the device under test as a heat source in the test chamber. By providing the air duct, air circulation device, uniform air outlet, and uniform air inlet, air is formed in an air circulation system in the box, thereby making the temperature distribution in the box more uniform and achieving better and more stable detection results.

[0005] Although the above-mentioned device can make the temperature distribution in the test box more uniform and achieve better and more stable detection effects, its air circulation device is arranged inside the box. Under the same volume, the test cavity in the box is smaller, and only a small number of base stations can be allowed to be tested in the test cavity, resulting in low test efficiency; and the air circulation device of the above-mentioned device has a complex structure and high manufacturing and processing costs; and the base station needs to be carried into the test cavity by staff before the test, and needs to be manually moved out after the test is completed. Although there is a sliding device to assist the base station in entering and exiting the test cavity, this can only assist the movement of the base station in the test cavity, and the base station is heavy, coupled with the high temperature state after the test, it is particularly difficult to move the base station out after the test.

[0018] Preferably, a plurality of universal wheels are provided at the bottom of the base.

[0019] The beneficial effects of the present invention are:

[0020] 1. An air circulation system is set up outside the box body. The hot air at the top of the test chamber is sucked out from the air outlet through the first fan, and then enters the bottom of the test chamber through the air inlet, which can speed up the air circulation in the test chamber and make the temperature inside the test chamber rise faster and more evenly. The air circulation system is set outside the box body, which reduces the space occupied by the box body. With the same volume, the test chamber space inside the box body is larger, which can accommodate more base stations for testing at the same time, thereby improving the test efficiency. At the same time, suction holes and blowing holes are opened on the circulating air duct, and blocking devices are set in the circulating air duct, the suction holes and the blowing holes to form a temperature control system. When the temperature control system is started, only the blocking device in the circulating air duct is not Allow gas to pass through, and the other sealing devices all allow gas to pass through. At this time, the outside gas enters the test chamber through the suction hole, circulation air duct and air inlet hole in turn, and the gas in the test chamber is discharged to the outside through the outlet hole, circulation air duct and blowing hole in turn, thereby realizing continuous gas exchange between the test chamber and the outside, thereby taking out the heat therein and realizing rapid cooling of the test chamber; when the air circulation system needs to be activated, the blocking state of the blocking device (whether gas is allowed to pass through) is opposite to the above; the temperature control system and the air circulation system share the circulation air duct, and the air circulation system and the temperature control system can be switched by adjusting the blocking state of the blocking device. The overall structure of the device is simple, easy to manufacture, and saving manufacturing costs.

[0021] 2. A transport device is provided, and a second slideway matching the slide rail at the bottom of the support seat is provided in the test chamber, and an active wheel driven by a right-angle motor and a driven wheel matched therewith are provided in the second slideway, and the support seat and the entire device thereon (including the base station) can be driven in and out of the test chamber by the active wheel. In this way, when a test is required, the staff only needs to transport the base station to the box through the transport device, and then use the push-pull handle provided on the support seat to push the support seat forward a short distance (the distance from the front end of the slide rail to the second slideway) so that the slide rail at its bottom contacts the second slideway, and the active wheel of the second slideway can drive the support seat into the test chamber; after the test is completed, the active wheel of the second slideway will transport the support seat out, and the operator only needs to pull the push-pull handle on the support seat (pull a short distance) to make the support seat detach from the box, and then pull the push-pull handle on the base to realize the transportation of the base station. Before and after the test, the staff does not need to enter the test chamber, which avoids high temperature burns to the staff. It is not only safe, but also simple to operate and labor-saving, thereby improving work efficiency.

[0022] 3. A first cross bar is set on both sides of the vertical bar of the base station bracket, and a bearing seat, a screw rod and a ball slider are set on the first cross bar. In this way, the position of the ball slider can be adjusted according to the size of different base stations, thereby adjusting the distance between the base stations, so that base stations of different sizes can maintain the set distance, thereby improving the applicability of the device.

[0023] 4. A slider is set on the hanging rod of the base station bracket. When you want to hang the base station, you can first slide the slider to the outermost end. After hanging the base station on the hook, directly push the slider to push the top of the base station to the designated position. This is more labor-saving than the staff directly carrying the bulky base station and hanging its top on the relatively inner hook.

[0024] 5. The vertical rod of the base station bracket is equipped with a slide cylinder. The height of the slide cylinder can be adjusted to adjust the contact position between the cylindrical rod and the base station. For base stations of different sizes, this adjustment can be used to keep the inclination angle of all base stations uniform, which also improves the applicability of the device (base stations of various sizes can use the same set of base station brackets).

[0042] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

[0043] It should be noted that the terms such as "upper", "lower", "left", "right", "front", "back", etc. cited in the invention are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0044] As shown in Figures 1 and 2, the present invention provides an antenna base station aging test box, including a box body 1, wherein a test cavity 2 is provided in the box body 1, the box body 1 is provided with an opening matching the test cavity 2, and a sealing door matching therewith is provided at the opening, and an air circulation system and a temperature control system are provided outside the box body 1, wherein the air circulation system includes an air outlet 21, an air inlet 22 and a circulating air duct 3, and the air outlet 21 and the air inlet 22 are opened on the box body 1 and communicate with the test cavity 2. In this embodiment, the air outlet 21 and the air inlet 22 are arranged at opposite corners of the same side wall of the box body 1, and the air outlet 21 is located on the upper side of the air inlet 22, that is, the air outlet 21 is arranged in the upper right corner, and the air inlet 22 is arranged in the lower left corner. It should be noted that the air outlet 21 and the air inlet 22 may not be arranged on the same side wall. For example, the air inlet 22 is arranged at the lower left corner of the front side wall (from the perspective of Figures 1 and 2), and the air outlet 21 is arranged at the upper right corner of the rear side wall (from the same perspective as above).

[0045] The circulating air duct 3 is arranged on the outside of the box body 1, and the circulating air duct 3 connects the air outlet 21 and the air inlet 22. A first fan 23 is provided in the circulating air duct 3, and the first fan 23 is arranged at a position close to the air inlet 22. The first fan 23 is used to suck out the gas from the air outlet 21 and then send it into the air inlet 22.

[0046] Because hot air floats above the test chamber 2 and cold air sinks to the bottom of the test chamber 2, the air outlet 21 and the air inlet 22 are set at opposite angles, and the air outlet 21 is located above the air inlet 22. The hot air at the top of the test chamber 2 is sucked out from the air outlet 21 by the first fan 23, passes through the circulating air duct 3 and then enters the bottom of the test chamber 2 through the air inlet 22. This can accelerate the convection of hot and cold air in the test chamber 2, making the temperature in the test chamber 2 rise faster and more evenly.

[0047] The temperature control system includes an air suction hole 31, an air blowing hole 32 and a blocking device 4. The air suction hole 31 and the air blowing hole 32 are provided on the circulating air duct 3. The air suction hole 31 and the air blowing hole 32 are raised pipes provided on the circulating air duct 3 as air holes. The opening of these two air holes allows the gas in the circulating air duct 3 to be exchanged with the outside air, which will be described in detail below.

[0048] The blocking device 4 can control the flow rate of airflow (in this device, it mainly allows airflow to pass through or completely prevents airflow from passing through); there are three blocking devices 4, two of which are respectively arranged in the suction hole 31 and the blowing hole 32, and the other is arranged in the circulating air duct 3 and located between the suction hole 31 and the blowing hole 32; a second fan 33 is provided on the blowing hole 32.

[0049] During the test, the blocking device 4 in the circulating air duct 3 allows the airflow to pass normally, while the blocking devices 4 in the air suction holes 31 and the air blowing holes 32 completely prevent the airflow from passing through, which is equivalent to blocking the air suction holes 31 and the air blowing holes 32; making the circulating air duct 3 a completely closed pipe, and only the gas circulation convection in the test chamber 2 is carried out.

[0050] When the test is completed and the test chamber 2 needs to be cooled, the blocking device 4 in the circulating air duct 3 blocks the air flow, which is equivalent to dividing the circulating air duct 3 into two independent pipes on the left and right; the blocking device 4 in the air suction hole 31 and the air blowing hole 32 allows the air flow to pass through, so that the circulating air duct 3 on the left side draws the outside air in through the air suction hole 31 by the first fan 23, and enters the test chamber 2 through the air inlet hole 22, while the air in the test chamber 2 is sucked out by the second fan 33 through the air outlet hole 21 and discharged to the outside air through the air blowing hole 32. In this way, the high-temperature air in the test chamber 2 can be discharged, and cold air can be continuously input into the test chamber 2 to continuously take out the heat in the test chamber 2, thereby achieving rapid cooling.

[0051] The air circulation system and the temperature control system share a circulating air duct 3, and the two systems are switched by a blocking device 4. The overall structure of the two systems is simple, the manufacturing cost is low, and it is easy to use; and the two systems are arranged on the outside of the box 1, do not occupy the volume of the box 1, and the test chamber 2 in the box 1 of the same volume has a larger space, can test multiple base stations at the same time, and improve the test efficiency.

[0052] A socket may be provided in the test cavity 2 to provide power to the base station, and a through hole and a sealing ring (same as disclosed in CN115913399B) may also be provided so that the plug of the base station can obtain power from the outside.

[0053] As shown in Figure 3, the blocking device 4 includes a shell 41, two blocking pieces 42 (the number of blocking pieces 42 can be set according to actual needs) and a first drive motor 43. The first drive motor 43 is installed on the outside of the shell 41, and the output shaft of the first drive motor 43 passes through the shell 41 and is connected to the blocking piece 42; the other end of the blocking piece 42 connected to the first drive motor 43 is rotatably connected to the inner wall of the shell 41; when all the blocking pieces 42 are rotated to be perpendicular to the axis of the shell 41 (for example, when the blocking device 4 is placed horizontally (with the top opening facing upward), the axis of the shell 41 is a vertical line), the blocking piece 42 completely blocks the inside of the shell 41, preventing airflow from passing through the inside of the shell 41; the blocking piece 42 is driven to rotate by the first drive motor 43, thereby adjusting the gas flow rate.

[0054] When installing, the blocking device 4 can be installed inside the circulating air duct 3, the suction hole 31 and the blowing hole 32. Such installation requires ensuring that the outer shell 41 is in contact with the inner walls of the circulating air duct 3, the suction hole 31 and the blowing hole 32, and is in a sealed state to prevent gas from flowing through the gaps; the circulating air duct 3 can also be divided into two left and right sections, which are respectively sealed and connected to the openings on both sides of the blocking device 4; and the suction hole 31 and the blowing hole 32 can be directly sealed and connected to their openings.

[0055] As shown in Figures 4 and 5, the present invention also provides a transport device 5 that matches the test chamber 2, including a base 51, a support base 52 and a base station bracket 9. The support base 52 is provided with two slide rails 53 at the bottom, and the top of the base 51 is provided with a first slide 54 that matches the slide rails 53; the base station bracket 9 is arranged on the top of the support base 52; the base 51 and the support base 52 are each provided with an independent push-pull handle to facilitate pushing and pulling the device; the bottom of the test chamber 2 is provided with a second slide 6 that matches the slide rail 53; the bottom of the base 51 is provided with a plurality of universal wheels 511.

[0056] As shown in FIG6 , a plurality of first rollers 61 are rotatably connected in the second slideway 6. The plurality of first rollers 61 located at the front end of the second slideway 6 serve as driving wheels, and the rest serve as driven wheels. By using only the first rollers 61 at the front end as driving wheels and the rest as driven wheels, kinetic energy can be saved, and the first rollers 61 at the front end can always maintain contact with the slide rail 53 (until the slide rail 53 is completely separated from the second slideway 6).

[0057] The driving wheel is provided with a protruding shaft 611 that passes through the side wall of the second slide 6, and a plurality of first gears 612 are provided on the protruding shaft 611; a right-angle motor 7 is provided at the bottom of the test chamber 2, and the right-angle motor 7 is located between the two second slides 6, and the output shaft of the right-angle motor 7 is connected to the two driving wheels opposite to the second slides 6 on both sides; a plurality of second gears 71 are provided on the output shaft of the right-angle motor 7; adjacent first gears 612 are connected by a transmission chain 8, and the second gear 71 and its adjacent first gear 612 are also connected by an independent transmission chain 8, but the transmission chain 8 connecting each two gears is independent of the transmission chain 8 connecting other gears.

[0058] The tops of the first slide 54 and the second slide 6 are rotatably connected to a plurality of second rollers 62 on the outside of the slide rail 53. The axes of the second rollers 62 are perpendicular to the length direction of the slide rail 53. The second rollers 62 can prevent the support seat 52 from shifting. The second rollers 62 are always in contact with the side walls of the slide rail 53, do not affect its sliding, and can prevent it from shifting in the left and right directions of the forward direction.

[0059] It should be noted that a plurality of first rollers 61 may also be provided in the first slideway 54 to reduce the friction during the sliding process of the slide rail 53 .

[0060] The right-angle motor 7 drives the driving wheel to rotate, so that the slide rail 53 on the first roller 61 can be driven to move back and forth in the second slide 6. In this way, before the test, the staff only needs to push the push-pull handle on the support seat 52 to push the support seat 52 together with the base station bracket 9 and the base station forward a short distance (the distance from the front end of the slide rail 53 to the second slide 6). When the slide rail 53 enters the second slide 6, the support seat 52 and the device thereon can be driven into the test chamber 2 under the action of the driving wheel; when the test is completed, the right-angle motor 7 is reversed, and the support seat 52 and the device thereon can be moved out of the test chamber 2 through the driving wheel. Before leaving the chamber, the base 51 is first moved to the opening of the box 1 so that the first slide 54 is opposite to the position of the slide rail 53, so that the slide rail 53 on the removed support seat 52 can fall into it, and finally pulled a short distance to completely separate the support seat 52 from the box 1. If the tested base station needs to be moved to another place, the push-pull handle on the base 51 can be used to push the base 51 to drive the entire conveying device 5 to move.

[0061] As shown in Figures 4 and 7, the base station bracket 9 includes a plurality of vertical rods 91, which are connected to the support base 52. The left and right sides of the top of the vertical rod 91 are connected to a first cross rod 92; a plurality of bearing seats 93 are provided on the top of the first cross rod 92, and a screw rod 94 is connected between the bearing seats 93. The screw rod 94 is connected to the output shaft of the second drive motor (in order to better show the main components, the second drive motor is omitted in the drawings). A ball slider 95 is connected to the screw rod 94. In this embodiment, screw rods 94 are only provided for the front and rear end ball sliders 95. The middle ball slider 95 is directly fixedly connected to the two first cross rods 92. Because the distance between adjacent base stations can be adjusted by adjusting the front and rear end ball sliders 95, of course, matching screw rods 94 and bearing seats 93 can also be provided for the middle ball slider 95.

[0062] Two hanging rods 96 are connected to the left and right sides of the ball slider 95 (only one can be set, and if there is only one, it can be set as a prismatic rod. It is preferably set as two or more to improve stability and prevent the hanging rod slider 97 from rotating around the hanging rod 96). The hanging rod 96 is slidably connected to the hanging rod slider 97 (that is, the hanging rod slider 97 is simultaneously mounted on the two hanging rods 96). The bottom of the hanging rod slider 97 is connected to a hook 98, and the base station is hung on the hook 98.

[0063] The hanging rod slider 97 is provided with an axial positioning device 102 (existing technology), which is used to control whether the hanging rod slider 97 can move on the hanging rod 96, so as to maintain the stability of the base station and prevent it from shaking during movement and deviating from the set position.

[0064] The second drive motor drives the screw rod 94 to rotate, so that the ball slider 95 moves back and forth along the screw rod 94, and then drives the base station mounted on the hook 98 to move back and forth. In this way, for base stations of different sizes, the distance between adjacent base stations can be flexibly adjusted. In this way, regardless of the size of the base station, the set distance can be maintained, thereby improving the applicability of the device.

[0065] The vertical rod 91 is provided with a slide (not shown in the accompanying drawings), and the left and right sides of the slide are connected to second cross bars 99. The front and rear ends of the second cross bars 99 are connected to connecting plates 100, and the connecting plates 100 are perpendicular to the second cross bars 99. Two cylindrical rods 101 are rotatably connected between the two connecting plates 101. The rotatable connection prevents wear on the surface of the base station during contact between the base station and the cylindrical rods 101. The distance from the cylindrical rods 101 to the second cross bar 99 increases from near to far from the top (that is, the plane formed by the axes of the two cylindrical rods 101 is in an inclined state, and the positional relationship of the two cylindrical rods 101 is specifically shown in FIG7 ).

[0066] The vertical rod 91 is provided with a plurality of threaded holes (not shown in the figure), and the slide is provided with through holes matching the threaded holes. The slide is fixed by means of positioning bolts cooperating with the threaded holes.

[0067] The cylindrical rod 101 is in contact with the base station, and the arrangement of the cylindrical rod 101 enables the base station to maintain a certain inclination angle. The slide can drive the second cross bar 99 (and thus the cylindrical rod 101) to move up and down, and adjust the contact position between the cylindrical rod 101 and the base station, so as to adapt to base stations of different sizes, so that base stations of different specifications can be tested at the set inclination angle.

[0068] The working principle of the antenna base station aging test box provided by the present invention is as follows:

[0069] Before the test, the hanging rod slider 97 is first moved to the outermost end of the hanging rod 96, and the staff hangs the base station on the hook 98, and then pushes the hanging rod slider 97 to the specified position at the inner end of the hanging rod 96, and locks the hanging rod slider 97 through the axial positioning device 102; the ball slider 95 is driven by the second drive motor to move, and the distance between adjacent base stations is adjusted to the set value, and the position of the slide is adjusted to make the inclination angle of the base station the set value (if the specific specifications of the base station are known, the ball slider 95 and the slide can also be adjusted in advance, which is more labor-saving and convenient), and then the transport device 5 is pushed to the opening of the box body 1, and the support seat 52 is pushed into the test cavity 2, and the right-angle motor 7 drives the active wheel to move the support seat 52 into the interior of the test cavity 2.

[0070] At this time, the air circulation system is turned on, the temperature control system is turned off (achieved through the sealing device 4, which has been explained in the previous text and will not be repeated here), the sealed door is closed, and the base station starts working after being powered on to generate a large amount of heat. The air circulation system accelerates the gas convection in the test chamber 2, performs internal circulation, and quickly achieves uniform temperature rise.

[0071] After the test is completed, the air circulation system switches to the temperature control system to achieve continuous exchange of external air with the air in the test chamber 2, thereby taking away the heat in the test chamber 2 and achieving rapid cooling in the test chamber 2. When the temperature reaches the appropriate value, the sealed door is opened, the right-angle motor 7 reverses, and the support base 52 is sent out of the test chamber 2 through the active wheel and falls onto the base 51, completing the entire test process.

[0072] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should be considered within the scope of protection of the present invention.
