[0039] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below 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 creative work are within the scope of protection of the present invention. Example

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Fig. 9 As shown, a street lamp lamp holder protection device for smart city roads includes a lamp holder 1, a plurality of lamp beads 2 are arranged on the lamp holder 1, an upper end surface of the lamp holder 1 is fixedly connected to a shell 3, a moisture-proof mechanism 4 is arranged on the shell 3, and the moisture-proof mechanism 4 includes a moisture absorption disk 42, the moisture absorption disk 42 is fixedly connected to the upper end surface of the shell 3 through a connecting seat 43, the lower end surface of the moisture absorption disk 42 extends to the inside of the shell 3 and is above the lamp holder 1, the upper end surface of the moisture absorption disk 42 extends outside the shell 3, the upper and lower ends of the moisture absorption disk 42 are respectively clamped with an upper cover plate 41 and a lower cover plate 44, and the moisture absorption disk 42 is filled with moisture absorbing particles;

[0041] The lower end surface of the upper cover plate 41 is fixedly connected with an isolation plate 45, and the lower end surface of the isolation plate 45 is slidably attached with a rotating plate 46, and the isolation plate 45 and the rotating plate 46 divide the moisture absorption disk 42 into two semicircular areas of the same size;

[0042] The upper cover plate 41 is provided with a plurality of drying holes 48, the area formed by the drying holes 48 is semicircular and is compatible with the isolation plate 45 and the rotating plate 46 dividing the moisture absorption disk 42 into two semicircular areas of equal size. The lower cover plate 44 is provided with a plurality of moisture absorption holes 47, the area formed by the moisture absorption holes 47 is semicircular and is compatible with the isolation plate 45 and the rotating plate 46 dividing the moisture absorption disk 42 into two semicircular areas of equal size.

[0043] In the embodiment, the street lamp works in an outdoor environment. Rain or humid air will make the inside of the street lamp damp, and the humid environment will damage the lamp holder. In the protective device provided by the present invention, the lower end of the moisture absorbing plate 42 is located above the lamp holder 1, and the moisture absorbing plate 42 is filled with moisture absorbing particles. At the same time, moisture absorbing holes 47 are opened in a partial area of ​​the lower cover plate 44 of the moisture absorbing plate 42. The moisture inside the street lamp will be absorbed by the moisture absorbing particles through the moisture absorbing holes 47, so that the air inside the street lamp is dry, thereby increasing the service life of the lamp holder.

[0044] It should be noted that the interior of the moisture absorption plate 42 is divided into two areas of equal size by the isolation plate 45 and the rotating plate 46. In one area, the lower cover plate 44 is provided with a moisture absorption hole 47, and the upper cover plate 41 of the area is closed without a drying hole 48, so that the air inside the street lamp can be dried and external water vapor can be prevented from entering. This area is the water absorption area. At the same time, the lower cover plate 44 of the other area is closed without a moisture absorption hole 47, and the upper cover plate 41 of the area is provided with a drying hole 48, and this area is the drainage area. The moisture absorption plate 42 is arranged above the heat sink 81 of the lamp holder 1, because after the heat sink 81 absorbs the temperature of the lamp holder 1, its own temperature rises, and the water molecules in the air in the lamp holder 1 are heated after contacting the heat sink 81, and have a tendency to move upward, so the moisture absorption effect of the moisture absorption plate 42 can be improved.

[0045] It is also necessary to understand that the upper cover plate 41 and the lower cover plate 44 of the moisture absorbing disk 42 are installed on the moisture absorbing disk 42 by snap-fitting, and the moisture absorbing disk 42 is detachably fixed to the outer shell 3 by the connecting seat 43, so the user can replace the internal moisture absorbing particles at any time, and can also replace the entire moisture absorbing disk 42.

[0046] like Figure 1 and Figure 3 As shown, a waterproof mechanism 7 is provided on the outer shell 3, and the waterproof mechanism 7 includes a waterproof box 74, and the waterproof box 74 is movably connected to the outer shell 3. The moisture-proof mechanism 4 is inside the waterproof box 74, and a second gear 73 is fixedly connected to one side of the waterproof box 74. The second gear 73 is fixedly connected to the upper end surface of the outer shell 3 by a bracket, and the second gear 73 is meshed with the first gear 72. The first gear 72 is fixedly connected to the output shaft of the waterproof motor 71, and the waterproof motor 71 is fixedly connected to the upper end surface of the outer shell 3.

[0047] In the embodiment, the waterproof box 74 can protect the moisture-proof mechanism 4 from being damaged by rain. When encountering clear weather, the waterproof motor 71 (the waterproof motor 71 is controlled by a humidity sensor, which is not shown in the humidity sensor control diagram) is started, driving the No. 1 gear 72 to rotate, the No. 1 gear 72 drives the No. 2 gear 73 to rotate, and the No. 2 gear 73 drives the waterproof box 74 to rotate, ultimately exposing the moisture-proof mechanism 4 to the external environment.

[0048] like Figure 4 , Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the lower end surface of the rotating plate 46 and the upper end surface of the lower cover plate 44 are slidably fitted, the lower end surface of the rotating plate 46 and the output shaft of the material changing motor 5 are fixedly connected, and the material changing motor 5 is fixedly connected to the lower end surface of the lower cover plate 44.

[0049] In the embodiment, when the waterproof box 74 no longer covers the moisture-proof mechanism 4, the material replacement motor 5 starts to drive the rotating plate 46 to rotate 180 degrees clockwise. When the rotating plate 46 rotates, it will push some moisture-proof particles in the water absorption area into the drainage area, and at the same time push some moisture-proof particles in the drainage area into the water absorption area, because the moisture-proof particles in the water absorption area have absorbed the moisture inside the street lamp in the previous work, and the water absorption capacity is reduced at this time, and the moisture-absorbing particles in the drainage area are in contact with the clear and dry air outside through the drying holes 48, so that the moisture-absorbing particles are dried. After the two moisture-absorbing particles are exchanged, the particles with stronger moisture absorption capacity enter the water absorption area, thereby improving the drying effect of the inside of the street lamp, and the particles with reduced moisture absorption capacity enter the drainage channel, but at this time the drying holes 48 in the drainage area can contact with the outside to dry the particles with reduced moisture absorption capacity, so that the moisture-absorbing particles can be recycled.

[0050] It should be noted that rainy weather is the main reason for the generation of water vapor inside street lamps. At this time, the moisture-absorbing particles in the water absorption area can be used for drying. When the weather is clear, the moisture-absorbing particles in the two areas are partially exchanged, so that the moisture-absorbing particles can be recycled, while also ensuring that there is no dust intrusion into the street lamps.

[0051] like Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a mixing mechanism 6 is provided in the rotating plate 46, and the mixing mechanism 6 includes a plurality of grooves 63, and the grooves 63 are provided at the upper end of the rotating plate 46, and a support spring 62 is fixedly connected to the bottom of the groove 63, and the upper end of the support spring 62 is fixedly connected to the lower end surface of the telescopic block 61, and the telescopic block 61 is slidably connected in the groove 63;

[0052] The lower end surface of the isolation plate 45 is configured as an arc surface, and the upper end surface of the telescopic block 61 is configured as an arc surface. The isolation plate 45 and the telescopic block 61 are matched with each other.

[0053] In the embodiment, when the rotating plate 46 rotates away from the isolation plate 45, the telescopic block 61 is not subject to the pressure of the isolation plate 45, and the supporting spring 62 extends to drive the telescopic block 61 to protrude from the groove 63. When the rotating plate 46 continues to rotate, the protruding telescopic block 61 will stir the moisture-proof particles in the moisture-absorbing disk 42 to prevent the moisture-proof particles from agglomerating and affecting the water absorption effect. At the same time, when some moisture-proof particles in the water absorption area and the drainage area are exchanged, the moisture-absorbing particles at different heights in the same area have different water absorption properties (because when the rotating plate 46 rotates, the moisture-absorbing particles at the bottom of the moisture-absorbing disk 42 will be exchanged first), and the rotating plate 46 can play a role in mixing the moisture-absorbing particles when driving the telescopic block 61 to rotate.

[0054] The workflow is as follows:

[0055] In actual use, because the street lamp is used in an outdoor environment, rainy days will make the inside of the street lamp damp and produce water vapor, which will damage the lamp holder and shorten the service life of the lamp holder. In the protection device provided by the present invention, the lower end of the moisture absorbing plate 42 is located above the lamp holder, and the moisture absorbing plate 42 is filled with moisture absorbing particles. At the same time, moisture absorbing holes 47 are opened in a partial area of ​​the lower cover plate 44 of the moisture absorbing plate 42. The moisture inside the street lamp will be absorbed by the moisture absorbing particles through the moisture absorbing holes 47, so that the air inside the street lamp is dry, thereby improving the service life of the lamp holder. The moisture absorbing plate 42 is arranged above the heat sink 81 of the lamp holder 1. Because the heat sink 81 absorbs the temperature of the lamp holder 1, its own temperature rises, and the water molecules in the air in the lamp holder 1 are heated after contacting the heat sink 81, and have a tendency to move upward, so the effect of the moisture absorbing plate 42 in absorbing moisture can be improved. At the same time, the upper cover plate 41 and the lower cover plate 44 of the moisture absorbing disc 42 are mounted on the moisture absorbing disc 42 by snapping, and the moisture absorbing disc 42 is detachably fixed to the outer shell 3 by the connecting seat 43, so the user can replace the internal moisture absorbing particles at any time, and can also replace the entire moisture absorbing disc 42. In humid or rainy weather, the waterproof box 74 can prevent the moisture-proof mechanism 4 from being eroded by rainwater. When the weather is clear, the waterproof motor 71 starts, driving the No. 1 gear 72 to rotate, the No. 1 gear 72 drives the No. 2 gear 73 to rotate, and the No. 2 gear 73 drives the waterproof box 74 to rotate, and finally the moisture-proof mechanism 4 is exposed to the external environment. At this time, the material replacement motor 5 starts to drive the rotating plate 46 to rotate 180 degrees clockwise. When the rotating plate 46 rotates, it will push some moisture-proof particles in the water absorption area into the drainage area, and at the same time push some moisture-proof particles in the drainage area into the water absorption area. Because The moisture-proof particles in the water absorption zone have absorbed the moisture inside the street lamp in the previous work, and the water absorption capacity is reduced at this time, while the moisture-absorbing particles in the drainage zone are in contact with the clear and dry air outside through the drying holes 48, thereby drying the moisture-absorbing particles. After the two moisture-absorbing particles are exchanged, the particles with stronger moisture absorption capacity enter the water absorption zone, thereby improving the effect of drying the inside of the street lamp, while particles with reduced moisture absorption capacity enter the drainage channel. However, at this time, the drying holes 48 in the drainage zone can be in contact with the outside to dry the particles with reduced moisture absorption capacity, so that the moisture-absorbing particles can be recycled. When the rotating plate 46 rotates away from the isolation plate 45, the telescopic block 61 is not subjected to the pressure of the isolation plate 45, and the supporting spring 62 extends to drive the telescopic block 61 to protrude from the groove 63. When the rotating plate 46 continues to rotate, the protruding telescopic block 61 will stir the moisture-proof particles in the moisture absorption disk 42 to prevent the moisture-proof particles from agglomerating and affecting the water absorption effect. At the same time, when some moisture-proof particles in the water absorption area and the drainage area are exchanged, the moisture-absorbing particles at different heights in the same area have different water absorption properties, and the rotating plate 46 can play a role in mixing the moisture-absorbing particles when driving the telescopic block 61 to rotate.
