[0042] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0045] See also Figures 1 to 3 As shown, a traditional street light includes a lamp post 500, an equipment compartment 200, and an inspection door 100. The equipment compartment 200 is provided on the lamp post 500, and the equipment compartment 200 is equipped with lighting equipment. The inspection door 100 can be movably provided in the equipment compartment 200. Specifically, the inspection door 100 includes a door panel 110 and a sealing plate 150. The door panel 110 has a hollow area 110a, and the sealing plate 150 is provided in the hollow area 110a to close the opening of the equipment compartment 200. Compared with traditional street lights, smart street lights 1000 will no longer just serve as simple lighting in the future. More and more functions and applications will be integrated into the lamp post 500. As the hub of the smart street light 1000, the equipment compartment 200 needs to improve the utilization rate of the internal space of the equipment compartment 200 while solving the problem of separate installation of weak current equipment 400 and strong current equipment 300. Based on this, the present invention proposes an inspection door 100 for the equipment compartment 200 and a smart street light 1000.

[0046] See also Figures 4 to 13As shown, in one embodiment of the present invention, a maintenance door 100 is provided for an equipment compartment 200, wherein the equipment compartment 200 is provided with a receiving space 200a having an opening, and the receiving space 200a receives a high-voltage device 300. The maintenance door 100 includes a door panel 110 and an isolation compartment 130, wherein the door panel 110 is movably arranged at the opening of the receiving space 200a, and the isolation compartment 130 is protruding from the surface of the door panel 110 facing the receiving space 200a, and the isolation compartment 130 is provided with a closed isolation space 130a, and the isolation space 130a is used to install a low-voltage device 400, so that when the door panel 110 is closed, the isolation compartment 130 with the low-voltage device 400 installed is received in the receiving space 200a.

[0047] When the technical solution of the present invention is applied to a smart street lamp 1000, the equipment cabin 200 is arranged on the lamp pole 500 of the smart street lamp 1000, the high-voltage equipment 300 is accommodated in the accommodation space 200a formed by the equipment cabin 200, the door panel 110 is movably arranged at the opening of the accommodation space 200a, the isolation cabin 130 is protruding from the surface of the door panel 110 facing the accommodation space 200a, and the low-voltage equipment 400 is accommodated in the isolation space 130a of the isolation cabin 130. In this way, when the door panel 110 is closed, the isolation cabin 130 installed with the low-voltage equipment 400 is accommodated in the accommodation space 200a, so that the accommodation space 200a of the equipment cabin 200 simultaneously accommodates the high-voltage equipment 300 and the isolation cabin 130 installed with the low-voltage equipment 400. Since the weak-current equipment 400 is accommodated in the accommodating space 200a of the equipment cabin 200 through the isolation cabin 130, interference from the strong-current equipment 300 outside the isolation cabin 130 is avoided. While achieving the separate installation of the strong-current equipment 300 and the weak-current equipment 400, the internal space of the equipment cabin 200 is fully utilized, thereby improving the utilization rate of the internal space of the equipment cabin 200.

[0048] It should be noted that in order to achieve the simultaneous accommodation of the equipment compartment 200 for the high-voltage equipment 300 and the isolation compartment 130 in which the low-voltage equipment 400 is installed, the space inside the lamp post 500 can be fully utilized to open a mounting groove of sufficient size, so as to be suitable for the installation of the corresponding equipment compartment 200. In the embodiment of the present invention, the door panel 110 can be installed in the equipment compartment 200 by means of a latch or by means of a hinge. Of course, the inspection door 100 can also be installed in the equipment compartment 200 by means of a combination of a latch and a hinge. As long as the inspection door 100 can be opened and closed at the opening of the accommodation space 200a, the embodiment of the present invention is not limited thereto, and the above is within the scope of protection of the present invention. Of course, in order to avoid interference of the strong current equipment 300 with the weak current equipment 400, the isolation cabin 130 is a structural member formed of electromagnetic shielding material. The isolation cabin 130 can be an integral structural member, and the isolation space 130a is formed by the integral structural member, or it can be a structural member including a cover plate 131, a middle frame 132 and a panel 133, etc., and a closed isolation space 130a is formed by sequentially setting the cover plate 131, the middle frame 132 and the panel 133. In this way, the weak current equipment 400 is installed in the closed isolation space 130a, thereby avoiding interference from the strong current equipment 300 in the accommodation space 200a. Compared with setting two equipment cabins 200 respectively along the height direction of the lamp pole 500, it is obvious that the equipment cabin 200 at a high place is not convenient for maintenance, and the additional equipment cabin 200 will also increase the cost. In addition, the waterproof level of weak current equipment 400, such as switches and network management, is only IP40, which is not waterproof or dustproof. Based on this, if the weak current equipment 400 is set in an open equipment compartment 200, the risk of water ingress will affect the service life of the weak current equipment 400. The present invention sets the isolation cabin 130 on the surface of the door panel 110 facing the accommodation space 200a, avoiding exposure of the weak-current equipment 400 and ensuring its service life. When the door panel 110 is closed, the strong-current equipment 300 and the weak-current equipment 400 in the isolation cabin 130 are arranged side by side and accommodated in the accommodation space 200a of the equipment cabin 200, thereby achieving full utilization of the internal space of the equipment cabin 200. Compared with the additional equipment cabin 200, the utilization rate of the internal space of the equipment cabin 200 is improved; when the door panel 110 is opened, the isolation cabin 130 moves with the door panel 110 to the outside of the equipment cabin 200, and the weak-current equipment 400 in the isolation cabin 130 deviates from the equipment cabin 200, thereby facilitating the inspection and maintenance of the strong-current equipment 300 inside the equipment cabin 200 and the weak-current equipment 400 in the isolation cabin 130. For additional explanation, see Figures 14 and 15As shown, the isolation chamber 130 in the present invention forms an isolated space 130a for mounting the weak current equipment 400. Thus, the isolation chamber 130, housing the weak current equipment 400, is mounted on the door panel 110, thereby completing the assembly of the access door 100. To transform a traditional street light into a smart street light 1000, only the isolation chamber 130 housing the weak current equipment 400 needs to be mounted on the door panel 110. This allows for a quick and convenient upgrade from a traditional street light to a smart street light 1000, reducing costs.

[0049] See also Figures 4 to 13 As shown, the isolation cabin 130 includes a cover 131, a middle frame 132 and a panel 133. The cover 131 and the panel 133 are respectively movably arranged on the two surfaces of the middle frame 132 to form a closed isolation space 130a. The weak current equipment 400 is arranged in the isolation space, and the panel 133 is installed on the door panel 100 with the surface facing away from the middle frame 132. Specifically, the middle frame 132 is a frame structure with two through sides, and the two surfaces of the frame structure are respectively provided with a first fixing hole 132a and a second fixing hole 132b. The cover plate 131 and the panel 133 are respectively located on both sides of the frame structure. The middle frame 132 is installed on the panel 133 by screws and the first fixing holes 132a, and the cover plate 131 is installed on the middle frame 132 by screws and the second fixing holes 132b. In this way, the cover plate 131, the middle frame 132 and the panel 133 enclose a closed isolation space 130a. Of course, in order to facilitate the maintenance of weak current equipment, at least one of the cover plate 131 and the panel 133 is movably provided on the middle frame 132. The movable methods include threaded connection, sliding connection and snap connection, etc. The embodiments of the utility model are not limited to this, and the above are all within the protection scope of the utility model. In addition, in order to improve the waterproof level of the isolation cabin 130, two sealing rings can be provided in the embodiment of the present invention, one sealing ring is used to seal the gap between the cover plate 131 and the middle frame 132, and the other sealing ring is used to seal the gap between the middle frame 132 and the panel 133, so that the waterproof level of the isolation cabin 130 is not lower than IP66, thereby ensuring the service life of the weak current equipment 400 in the isolation cabin 130, thereby ensuring the service life of the smart lamp pole 500.

[0050] See also Figures 4 to 13As shown, in one embodiment of the present invention, the middle frame 132 is movably mounted on the panel 133, and a first sealing ring 134 is provided between the panel 133 and the middle frame 132. The first sealing ring 134 is used to seal the gap between the middle frame 132 and the panel 133. It should be noted that in order to better position the installation of the first sealing ring 134, the embodiment of the present invention is provided with a first mounting groove on the surface of the panel 133, and the first sealing ring 134 is provided in the first mounting groove. In this way, the middle frame 132 is mounted on the panel 133 by squeezing the first sealing ring 134, thereby sealing the gap between the middle frame 132 and the panel 133, thereby preventing external water from flowing through the gap to the weak current equipment 400, preventing the internal weak current equipment 400 from being damaged by water, and thus improving the waterproof level of the isolation cabin 130.

[0051] See also Figures 4 to 13 As shown, in one embodiment of the present invention, the cover plate 131 is movably mounted on the middle frame 132, and a second sealing ring 135 is provided between the cover plate 131 and the middle frame 132. The second sealing ring 135 is used to seal the gap between the cover plate 131 and the middle frame 132. It should be noted that in order to better position the installation of the second sealing ring 135, the embodiment of the present invention is provided with a second mounting groove on the surface of the cover plate 131, and the second sealing ring 135 is provided in the second mounting groove. In this way, the cover plate 131 is mounted on the middle frame 132 by squeezing the second sealing ring 135, thereby sealing the gap between the middle frame 132 and the cover plate 131, thereby preventing water in the equipment compartment 200 from flowing through the gap to the weak current equipment 400, and improving the waterproof level of the isolation compartment 130.

[0052] See also Figures 4 to 13 As shown, in one embodiment of the present invention, the surface of the panel 133 is provided with two fixing grooves 133a spaced apart along the width direction of the door panel 110, and the weak current device 400 is positioned and installed in the isolation space 130a through the two fixing grooves 133a. It should be noted that during the installation process of the weak current device 400, the bar hoop of the weak current device 400 is aligned with the fixing groove 133a of the panel 133, and screws are sequentially passed through the bar hoop and the fixing groove 133a to achieve the installation of the weak current device 400 on the panel 133. After the installation of the weak current device 400 is completed, the middle frame 132 is fixed to the panel 133. Of course, in order to adapt to the installation of different types of weak current devices 400, the fixing groove 133a of the embodiment of the present invention extends along the height direction of the door panel 110. In this way, different types of weak current devices 400 are installed and fixed through the fixing grooves 133a at different positions, achieving stable installation in the isolation cabin 130.

[0053] See also Figures 4 to 13As shown, in one embodiment of the present invention, the door panel 110 is formed with a hollow area 110a, and a plurality of heat dissipation ribs 136 are protruding from the surface of the isolation cabin 130 facing away from the accommodating space 200a, and the plurality of heat dissipation ribs 136 are exposed in the hollow area 110a of the door panel 110. Specifically, the door panel 110 includes four frame bars, which are connected end to end in sequence to form a frame structure having the door panel 110, and a plurality of heat dissipation ribs 136 arranged at intervals are exposed in the hollow area 110a. In this way, the heat generated by the weak current equipment 400 is conducted to the heat dissipation ribs 136 through the shell of the isolation cabin 130, and the heat dissipation ribs 136 are exposed to the outside world, thereby realizing the conduction of heat to the outside air, achieving the effect of quickly cooling the weak current equipment 400, and being compatible with the heat dissipation requirements of the weak current equipment 400.

[0054] See also Figures 4 to 13 As shown, in one embodiment of the present invention, the door panel 110 includes two frame bars arranged opposite to each other, one frame bar is used to be rotatably connected to the equipment compartment 200, and the other frame bar is provided with a lock 111 that cooperates with the equipment compartment 200, so that the door panel 110 can be opened or closed by rotation under the cooperation of the lock 111. It should be noted that, of the two frame bars, one frame bar can be rotatably mounted on the equipment compartment 200 by a latch, or can be rotatably mounted on the equipment compartment 200 by a hinge. Of course, the door panel 110 can also be rotatably mounted on the equipment compartment 200 by a latch and a hinge; the equipment compartment 200 is provided with a lock slot, and the other frame bar is provided with a lock 111 that cooperates with the lock slot of the equipment compartment 200.
