[0044] A T-shaped support arm 301 is fixed on the bottom tray 3. The T-shaped support arm 301 is a stainless steel support arm. The AC / DC power module 5, the water immersion sensor module 6 and the intelligent switch module 7 are installed on the T-shaped support arm 301. The T-shaped support arm 301 can prevent rainwater from penetrating along the inner wall of the box body 1 and damaging the electrical modules.

The upper end of the water leakage sensing line 601 is connected to the water immersion signal converter 603 through the water leakage line interface 602. The RS485 water immersion sensor communication interface 604 is connected to the RS485 intelligent switch communication interface 705 of the intelligent switch module 7. When the water leakage sensing line 601 detects water immersion, the water immersion signal converter 603 immediately sends an alarm linkage signal to the intelligent switch module 7.

[0047] The intelligent switch module 7 adopts the existing mature power monitoring switch module, which has the functions of automatically monitoring the output power of the isolation transformer 4, receiving the alarm linkage signal of the water immersion sensor module 6, and automatically opening / closing the power supply circuit composed of the secondary cable 10 according to the preset threshold and the received alarm linkage signal; the intelligent switch module 7 is externally provided with a liquid crystal display 701, a setting button 702, a debugging interface 703, a cable input / output interface 704, an RS485 intelligent switch communication interface 705, a DC intelligent switch power supply interface 706, etc.; the liquid crystal display 701 is used to display the monitored The output voltage, current and other electrical quantity values ​​of the isolation transformer 4 and the switch status of the secondary cable power supply circuit; the setting button 702 can set the electrical quantity alarm threshold; the debugging interface 703 can be connected to a PC to configure the intelligent switch module 7; the cable input / output interface 704 is used to connect the power supply circuit composed of the secondary cable connector 402 and the front-end navigation lamp 13 through the secondary cable 10 to power the front-end navigation lamp 13; the RS485 signal input / output interface 705 is connected to the water immersion sensor module 6, and can communicate with the navigation light monitoring system to upload monitoring data when the network conditions are met.

[0048] like Figure 6 As shown, the primary cable jumper 9 includes a primary cable line 901, and a primary cable jumper connector 902 and an AC power connector 903 arranged at the end of the primary cable line 901; the length of the primary cable line 901 is determined according to the distance between adjacent light boxes, the primary cable jumper connector 902 is used to connect to the primary cable connector 401 of the isolation transformer 4, and the AC power connector 903 is used to connect to the power input interface 501 of the AC / DC power module 5AC. The primary cable jumper 9 can adopt a machine-prefabricated finished cable and can be plugged and played.

[0049] like Figure 7 and 8As shown, the transverse interface component 8 includes a connecting steel pipe 801, a ferrule-type metal pipe joint 802, a sealing cap 803 and a sealing component 804, etc.; the connecting steel pipe 801 is made of a DN25 steel pipe, and the outer walls of both ends are provided with sleeve threads 8011, and the connecting steel pipe 801 is welded in the primary wire pipe reserved hole 101 of the box body 1; the ferrule-type metal pipe joint 802 adopts an existing product on the market, and the sleeve end is embedded with threads, and the ferrule-type metal pipe joint 802 is sleeved on the sleeve thread 8011 at the outer end of the connecting steel pipe 801, and the ferrule-type metal pipe joint 802 is sleeved on the sleeve thread 8011 at the outer end of the connecting steel pipe 801. The other end of the connector 802 is connected to the flexible metal tube 14. After the connection and installation of the ferrule metal tube connector 802 is completed, glass glue is used to seal the joint. When the outer port of the connecting steel tube 801 is not in use, it is sealed with sealant; the sealing cap 803 is made of plastic, with an embedded thread, and is sleeved on the sleeve thread 8011 at the inner end of the connecting steel tube 801; a sealing assembly 804 is provided in the inner port of the connecting steel tube 801, and the sealing assembly 804 is sealed with the primary cable jumper 9 and the grounding jumper 12.

[0050] like Fig. 9 and 10 As shown, the sealing assembly 804 includes a T-shaped rubber sealing pad 804-1 and a snap-on blocking gasket 804-2. The T-shaped rubber sealing pad 804-1 is made of waterproof rubber and consists of two cylinders with different diameters. The diameter of the thin end is adapted to the inner diameter of the connecting steel pipe 801, and the diameter of the thick end is adapted to the outer diameter of the connecting steel pipe 801. A primary cable threading hole 804-1-1 and a grounding cable threading hole 804-1-2 are reserved in the middle of the T-shaped rubber sealing pad 804-1. The diameters thereof are adapted to the outer diameters of the primary cable and the grounding cable, respectively. A movable transverse seam 804-1-3 is reserved on one side of the T-shaped rubber sealing pad 804-1. The movable transverse seam 804-1-3 divides the primary cable threading hole 804-1-1 and the grounding cable threading hole 804-1-2 into two. The snap-fit ​​blocking gasket 804-2 is made of stainless steel, and its outer diameter is the same as the inner diameter of the connecting steel pipe 801. A C-shaped bayonet 804-2-1 is provided on the snap-fit ​​blocking gasket 804-2, and its opening width is adapted to the outer diameter of the primary cable jumper 9.

[0051] After the primary cable jumper 9 and the ground jumper 12 are laid through the connecting steel pipe 801, open the movable transverse seam 804-1-3 on the T-shaped rubber sealing pad 804-1, and insert the primary cable jumper 9 and the ground jumper 12 into the primary cable threading hole 804-1-1 and the grounding cable threading hole 804-1-2 respectively, and then insert the thin end of the T-shaped rubber sealing pad 804-1 into the inner port of the connecting steel pipe 801, and then use the C-shaped blocking gasket card 804 to clamp the primary cable jumper 9 and the ground jumper 12 and press them on the top of the thick end of the T-shaped rubber sealing pad 804-1, and finally cover it with the sealing cap 803 and sleeve it on the inner port of the connecting steel pipe 801 to seal it.

[0052] The functions that can be realized by the airport navigation light box that can be quickly installed adjacent to each other in this embodiment include:

[0053] When the intelligent switch module 7 detects that the output power of the isolation transformer 4 is less than a certain threshold, the light intensity of the front-end navigation lamp 13 will not meet the aircraft approach requirements, or when the intelligent switch module 7 detects that the output power of the isolation transformer 4 fluctuates and is momentarily greater than a certain threshold, which may damage the front-end navigation lamp 13, or when the intelligent switch module 7 receives the alarm linkage signal of the water immersion sensor module 6, or when the intelligent switch module 7 itself is damaged, it automatically cuts off the power supply circuit formed by the secondary cable 10, turns off the front-end navigation lamp 13, and enables the navigation light monitoring system to quickly detect the circuit breaker signal of the front-end navigation lamp 13 and issue an alarm, prompting the on-duty personnel to go for maintenance.

[0054] When the operation and maintenance personnel conduct on-site inspection, they can observe the situation inside the box body 1 through the transparent box cover 2, directly read the voltage, current, switch status and other data on the LCD screen 701, and judge the fault;

[0055] After the output power of the isolation transformer 4 returns to normal and the alarm linkage signal of the water immersion sensor module 6 is eliminated, the intelligent switch module 7 automatically connects the power supply circuit formed by the secondary cable 10, turns on the front-end navigation light 13, and provides the aircraft with a navigation light approach guidance signal.

[0056] The multi-level waterproofing measures implemented by the airport navigation light box that can be quickly installed adjacent to each other in this embodiment are as follows:

[0057] Installing a rubber gasket seal 204 on the inner side of the cover edge 202 of the box cover 2 to prevent water seepage is the first level waterproof measure, and using the bottom tray 3 to install the isolation transformer 4 and AC / DC power module 5, water immersion sensor module 6, intelligent switch module 7 and other electrical modules to prevent the electrical performance from being damaged when a small amount of water enters is the second level waterproof measure;

[0058] After the ferrule metal pipe joint 802 is installed on the outer port of the connecting steel pipe 801 of the horizontal interface assembly 8, glass glue is used to seal the joint, or when the outer port of the connecting steel pipe 801 is not in use, it is sealed with sealant, which is the first level waterproof measure; T-shaped rubber sealing pad 804-1 and sealing cap 803 are installed on the inner port of the connecting steel pipe 801 as the second level waterproof measure;

[0059] After the secondary cable 10 is laid, both ends of the secondary wire tube 103 are sealed with sealant to prevent water seepage, forming a two-level waterproof measure;

[0060] When water penetrates into the box 1 and triggers the water leakage sensing line 601, the water immersion sensor module 6 immediately sends an alarm linkage signal to the intelligent switch module 7. After receiving the alarm linkage signal, the intelligent switch module 7 automatically cuts off the power supply circuit of the front-end navigation light 13 and sends an alarm prompt to the navigation light monitoring system platform for maintenance, which is a third-level waterproof measure.

[0061] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
