Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and more specifically, to an outdoor telecommunications base station cabinet. Background Technology

[0002] Telecommunications cabinets are specialized enclosures used to install and protect communication equipment, playing a crucial role in modern communication networks. They are typically made of cold-rolled steel or alloy materials, which not only provide physical protection but also effectively shield against electromagnetic interference, ensuring stable signal transmission between devices.

[0003] A search revealed that utility model patent CN222192891U discloses an outdoor telecommunications base station cabinet, including a cabinet body. The top of the cabinet body has evenly distributed top heat dissipation slots, and the left and right sides of the cabinet body also have evenly distributed side heat dissipation slots. Fixed columns are installed at the four corners of the top of the cabinet body, and a rainproof top plate is installed on the top of multiple sets of fixed columns. Raindrop detection sensors are installed at the corners of the top of the rainproof top plate. In this patent, when the outdoor telecommunications base station cabinet encounters rain, snow, or strong winds, the side shielding plates will close, covering the side heat dissipation slots. The top heat dissipation slots will then be used for normal heat dissipation, preventing rainwater or debris blown up by strong winds from entering the cabinet through the side heat dissipation slots, thus protecting the internal telecommunications equipment. This design is flexible and provides excellent protection for the internal telecommunications equipment.

[0004] However, the aforementioned patent has the following shortcomings: although the rainproof side panel can be opened and closed by driving gears and racks, the gears and racks are directly exposed to the outside, making them susceptible to external debris and compromising the stability of the side panel's movement; furthermore, when rain and wind occur simultaneously, rainwater will be blown by the wind to the bottom of the rainproof top panel, allowing rainwater to enter the cabinet from the top heat dissipation vents. Therefore, we propose an outdoor telecommunications base station cabinet. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an outdoor telecommunications base station cabinet.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] An outdoor telecommunications base station cabinet includes a cabinet body. The side of the cabinet body has multiple louvered openings. A shielding mechanism is provided on the top of the cabinet body. A telescopic cylinder is fixedly connected to the side of the cabinet body. A first motor is fixedly installed at one end of the inner cavity of the telescopic cylinder. A screw is fixedly connected to the output shaft of the first motor. A telescopic column is threaded onto the end of the screw. One end of the telescopic column extends to the outside of the telescopic cylinder and is fixedly connected to a shielding side plate. Multiple shielding grooves are formed on the inner side of the shielding side plate. The inner wall of the shielding grooves fits against the outer side of the louvered openings. The inner side of the shielding side plate fits against the side of the cabinet body. Multiple heat dissipation grooves are formed on the top surface of the cabinet body. A first filter screen is fixedly fitted onto the top of the inner cavity of each heat dissipation groove.

[0008] As a preferred embodiment of this utility model, the shielding mechanism includes multiple electric push rods fixedly installed on the top of the cabinet's inner cavity and multiple heat exchange copper pipes fixedly sleeved within the cabinet's inner cavity. The bottom end of each heat exchange copper pipe extends to the bottom of the cabinet, and the top end extends to the top of the cabinet. The output ends of the multiple electric push rods all extend to the top of the cabinet and are fixedly connected to a rain shield. Multiple water pipes are fixedly sleeved on the rain shield, and the bottom ends of the multiple water pipes are movably sleeved into the inner cavity of the heat exchange copper pipes. A water collection frame is fixedly connected to the top surface of the rain shield. Two mounting seats are fixedly connected to the top of the inner cavity of the water collection frame. A raindrop detection sensor is provided on the top surface of one mounting seat, and a wind detector is provided on the top surface of the other mounting seat. A second filter screen is fixedly sleeved on the top of the inner cavity of the water collection frame.

[0009] As a preferred embodiment of this utility model, a controller is fixedly installed on the inner wall of the cabinet, and the controller is electrically connected to the electric push rod, the raindrop detection sensor, the wind detector, and the first motor.

[0010] As a preferred embodiment of this utility model, the cabinet body is hinged to a cabinet door on the front.

[0011] In a preferred embodiment of this utility model, the side of the telescopic column is in contact with the inner wall of the telescopic cylinder.

[0012] In a preferred embodiment of this utility model, the inner wall of the heat exchange copper tube is in contact with the side of the water pipe.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) In this utility model, when the raindrop detection sensor detects rain or snow outside, the first motor drives the screw to rotate. Through the threaded engagement between the screw and the telescopic column, the telescopic column is driven to retract into the inner cavity of the telescopic cylinder. The telescopic cylinder drives the shielding side plate to move to the side of the louver hole to block it. At the same time, the first motor and the screw are both located in the inner cavity of the telescopic cylinder and will not be affected by the external environment, thus ensuring the stability of the structure during use.

[0015] (2) In this utility model, when the raindrop detection sensor and the wind detector detect that rain, snow and strong wind occur simultaneously outside, the side of the louver hole is blocked by the shielding side plate. The rain shield is moved down by the electric push rod, so that the side of the rain shield is wrapped around the outside of the cabinet and the top of the cabinet door. This prevents the strong wind from blowing rainwater to the top of the cabinet. The rainwater flowing through the water pipe and the heat exchange copper pipe cools the inner cavity of the cabinet, preventing rainwater from entering the cabinet and ensuring the cooling effect on the inner cavity of the cabinet. It is practical. Attached Figure Description

A shielding mechanism 3 is provided on the top of the cabinet body 1. A telescopic cylinder 6 is fixedly connected to the side of the cabinet body 1. A first motor 7 is fixedly installed at one end of the inner cavity of the telescopic cylinder 6. A screw 8 is fixedly connected to the output shaft of the first motor 7. A telescopic column 9 is threaded onto the end of the screw 8. One end of the telescopic column 9 extends to the outside of the telescopic cylinder 6 and is fixedly connected to a shielding side plate 10. Multiple shielding grooves 11 are provided on the inner side of the shielding side plate 10. The inner wall of the shielding groove 11 fits against the outer side of the louvered openings 2. The inner side of the shielding side plate 10 fits against the side of the cabinet body 1. Multiple heat dissipation grooves 4 are provided on the top surface of the cabinet body 1. A first filter screen 5 is fixedly sleeved on the top of the inner cavity of the heat dissipation groove 4.

[0027] In this embodiment, the louvered openings 2 and the heat dissipation grooves 4 are used to ventilate and dissipate heat in the inner cavity of the cabinet 1.

[0028] For details, please refer to Figures 1 to 3The shielding mechanism 3 includes multiple electric push rods 12 fixedly installed on the top of the inner cavity of the cabinet 1 and multiple heat exchange copper pipes 15 fixedly sleeved in the inner cavity of the cabinet 1. The bottom end of the heat exchange copper pipes 15 extends to the bottom of the cabinet 1, and the top end of the heat exchange copper pipes 15 extends to the top of the cabinet 1. The output ends of the multiple electric push rods 12 all extend to the top of the cabinet 1 and are fixedly connected to a rain shield 13. Multiple water pipes 16 are fixedly sleeved on the rain shield 13. The bottom ends of the multiple water pipes 16 are movably sleeved in the inner cavity of the heat exchange copper pipes 15. A water collection frame 14 is fixedly connected to the top surface of the rain shield 13. Two mounting seats 17 are fixedly connected to the top of the inner cavity of the water collection frame 14. A raindrop detection sensor 18 is provided on the top surface of one mounting seat 17, and a wind detector 19 is provided on the top surface of the other mounting seat 17. A second filter screen 20 is fixedly sleeved on the top of the inner cavity of the water collection frame 14.

[0029] In this embodiment, the second filter screen 20 is used to prevent debris from entering the inner cavity of the water receiving frame 14, and the water receiving frame 14 is used to collect rainwater.

[0030] For details, please refer to Figures 1 to 4 A controller 22 is fixedly installed on the inner wall of the cabinet 1. The controller 22 is electrically connected to the electric push rod 12, the raindrop detection sensor 18, the wind detector 19, and the first motor 7.

[0031] In this embodiment, the controller 22 processes the information detected by the raindrop detection sensor 18 and the wind detector 19, and controls the electric push rod 12 and the first motor 7.

[0032] For details, please refer to Figure 1 Cabinet 1 has a cabinet door 21 hinged to its front.

[0033] For details, please refer to Figure 4 The side of the telescopic column 9 fits against the inner wall of the telescopic cylinder 6.

[0034] In this embodiment, the inner wall of the telescopic cylinder 6 is used to limit the telescopic column 9, so that the telescopic column 9 can only move along the axial direction of the screw 8.

[0035] For details, please refer to Figure 2 The inner wall of the heat exchange copper tube 15 is in contact with the side of the water pipe 16.

[0036] In this embodiment, the airtightness between the heat exchange copper tube 15 and the water pipe 16 is ensured.

[0037] Working principle: During use, the cabinet 1 is ventilated and cooled through the heat dissipation groove 4 and the louver holes 2. The raindrop detection sensor 18 senses whether the external environment is rainy or snowy, and the wind detector 19 senses whether the external environment is windy. When the raindrop detection sensor 18 detects that the external environment is only rainy or snowy, the controller 22 controls the first motor 7 to start. The first motor 7 drives the screw 8 to rotate. Through the threaded engagement between the screw 8 and the telescopic column 9, the telescopic column 9 is driven to retract into the inner cavity of the telescopic cylinder 6, so that the side panel 10 moves to the side of the louver hole 2, thereby blocking the louver hole 2. The heat dissipation groove 4 ventilates and cools the inner cavity of the cabinet 1 at this time. In addition, the water receiving frame 14 catches the falling rainwater, and the rainwater in the water receiving frame 14 flows down the water pipe 16, so that the rainwater flows in the inner cavity of the heat exchange copper pipe 15. At the same time, the rainwater in the inner cavity of the heat exchange copper pipe 15 and the heat in the inner cavity of the cabinet 1 are used for heat exchange, thereby cooling the inner cavity of the cabinet 1.

[0038] When the raindrop detection sensor 18 and the wind detector 19 detect rain, snow and strong winds simultaneously, on the one hand, the shielding side panel 10 blocks the side of the louver hole 2, and on the other hand, the electric push rod 12 is activated to move the rain shield 13 down, so that the side of the rain shield 13 fits over the outside of the cabinet body 1 and the top of the cabinet door 21, preventing the strong wind from blowing rainwater to the top of the cabinet body 1. At this time, the rainwater flowing through the water pipe 16 and the inner cavity of the heat exchange copper pipe 15 heats and cools the inner cavity of the cabinet body 1.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
