DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] like Figure 1-9 As shown, a mounting module for a battery compartment of a photovoltaic street lamp includes a lamp post 1, a lighting assembly 2 and a photovoltaic assembly 3. A battery 40 electrically connected to the lighting assembly 2 and the photovoltaic assembly 3 is arranged at the bottom of the lamp post 1. The lamp post 1 also includes a base compartment 4 arranged at the bottom of the lamp post 1. The base compartment 4 includes a base shell 41 and a dome cover 42 arranged in the base shell 41, and a sandwich portion is clamped therebetween. The dome cover 42 is provided with heat dissipation fins 421 in a linear array. The battery 40 is arranged in the dome cover 42, and the sandwich portion is connected to the outside.

[0034] Specifically, the base shell 41 is provided with angle codes, and the base shell 41 is fixed to the ground by fasteners and concrete. The dome cover 42 is arranged in the base shell 41, and an interlayer portion is clamped between the dome cover 42 and the base shell 41. The interlayer portion is provided with a through groove connected to the outside. When the base cabin 4 is installed in the green belt, the low-temperature moisture in the green belt will enter the interlayer along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421, and at the same time, it can isolate moisture with a large amount of water, so as to protect the battery 40 and cool it down at the same time, thereby extending the service life of the battery 40.

[0035] Furthermore, the lighting assembly 2 includes a fixing sleeve 22 disposed on the lamp post 1 , a connecting frame 221 is disposed on the fixing sleeve 22 , and an LED lamp 21 electrically connected to the battery 40 is disposed on the connecting frame 221 .

[0036] In the above technical solution, the dome cover 42 and the base shell 41 are sleeved outside the battery 40 to isolate the external moisture. The dome cover 42 and the base shell 41 form a sandwich part. When the lamp post 1 is arranged in the green belt, the gas with low temperature and high humidity in the green belt will enter the sandwich part to cool the battery 40 in the dome cover 42 through the heat dissipation fins 421. While cooling, it can prevent moisture from directly contacting the battery 40, thereby reducing the corrosion rate of the battery 40.

[0037] As an embodiment provided by the present invention, the photovoltaic assembly 3 includes a bearing frame 32 fixedly connected to the lamp post 1, a mixing channel 12 is provided in the lamp post 1, and the interlayer part and the dome cover 42 are driven to supply gas to the mixing channel 12 and cool the photovoltaic panel 31 on the bearing frame 32;

[0038] The dome cover 42 is provided with a gathering pipe 43 extending into the mixing channel 12, and the gathering pipe 43 and the mixing channel 12 are embraced to form a suction channel.

[0039] Specifically, the photovoltaic assembly 3 includes a bearing frame 32 arranged on the top of the lamp post 1, a cooling chamber 321 is provided on the bearing frame 32, and the photovoltaic panel 31 is arranged on the cooling chamber 321. The interior of the lamp post 1 is hollow, and a mixing channel 12 is arranged in the hollow interior. The diameter of the gathering pipe 43 is smaller than that of the mixing channel 12, and the two are arranged coaxially. The end of the mixing channel 12 is fixedly connected to the output head 11, and the output head 11 extends into the cooling chamber 321. The gathering pipe 43 extends into the mixing channel 12, and there is a gap between the two. Neutral gear, which is the suction duct, is fixedly connected with the interlayer part. The temperature in the dome cover 42 rises with the use of the battery 40, and the heated airflow is discharged along the gathering pipe 43, so as to suck the humid and cold gas in the interlayer part through the Venturi structure, so as to promote the flow of humid and cold gas and increase the cooling of the heat dissipating fins 421. At the same time, the humid and cold gas and the gas discharged from the gathering pipe 43 are mixed in the mixing channel 12 and input into the cooling chamber 321 to continue cooling the photovoltaic panel 31.

[0040] The low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool down the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then, the temperature in the dome cover 42 will increase with the use of the battery 40, and the heated air flow will be discharged along the gathering pipe 43 to suck the wet and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue cooling the photovoltaic panel 31.

[0041] As an embodiment provided by the present invention, a return channel is clamped between the mixing channel 12 and the lamp post 1 , and an air outlet of the return channel faces the bottom of the dome cover 42 .

[0042] Specifically, the first end of the mixing channel 12 (with Figure 3For reference, the first section is the lower end) is provided with an isolation plate 121, a return channel is clamped between the mixing channel 12 and the lamp post 1, the isolation plate 121 isolates the return channel and the interlayer part, the return channel is fixedly connected to the cooling bin 321, and the return channel outlet faces the bottom of the dome cover 42. When the gas in the dome cover 42 is discharged along the gathering pipe 43, the return channel will be sucked to make the airflow in the cooling bin 321 flow along the return channel. The mixed airflow in the mixing channel 12 is stably lower than the temperature of the cooling bin 321, so that the airflow is cooled and then input into the dome cover 42. The moisture in the bushes is mixed in the mixing channel 12 and flows along the cooling bin 321 and the return channel, so that the moisture in the moisture is reduced. After the moisture is reduced, it enters the dome cover 42 through the return channel to cool the battery 40.

[0043] The low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then, the temperature in the dome cover 42 will rise as the battery 40 is used, and the heated airflow will be discharged along the gathering pipe 43 to suck the wet and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue cooling the photovoltaic panel 31. At this time, the moisture in the moisture is reduced and discharged with the gas in the dome cover 42, which will suck the airflow in the cooling chamber 321, so that the airflow flows along the return channel to the bottom of the dome cover 42 for circulation.

[0044] As an embodiment provided by the present invention, a plurality of guide pipes 122 are arranged in a circumferential array on the mixing channel 12 , and the guide pipes 122 pass through the dome cover 42 toward the bottom of the battery 40 .

[0045] Specifically, the guide tubes 122 are arranged in a circular array on the isolation plate 121. When the lamp post 1 is set on a highway (asphalt or plastic road), the base cabin 4 has a higher temperature because it is close to the ground, while the photovoltaic component 3 has a lower temperature. At this time, the interlayer part and the dome cover 42 float up due to heating, increasing the gas supply to the cooling chamber 321 to squeeze the cooling chamber 321, and squeeze the gas in the cooling chamber 321, which is lower in temperature than the bottom, into the dome cover 42 along the return channel.

[0046] When the lamp post 1 is set in the green belt, the low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then the temperature in the dome cover 42 rises with the use of the battery 40, and the heated air flow is discharged along the gathering pipe 43 to suck the wet and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue cooling the photovoltaic panel 31. At this time, the moisture in the The moisture content is reduced and discharged along with the gas in the dome cover 42, which will draw the airflow in the cooling chamber 321, causing the airflow to flow to the bottom of the dome cover 42 along the return channel for circulation. When the lamp post 1 is set on a highway (asphalt or plastic road), the interlayer part and the dome cover 42 will float up due to heating, increasing the air supply to the cooling chamber 321, thereby squeezing the cooling chamber 321, and squeezing the gas in the cooling chamber 321, which is lower in temperature than the bottom, into the dome cover 42 along the return channel for cooling.

[0047] As an embodiment provided by the present invention, the dome cover 42 is driven to move along the base shell 41 to fix the battery 40;

[0048] A spring 402 is disposed on the inner wall of the top of the dome cover 42 , and a push ring 403 is disposed on the spring 402 . The push ring 403 fits the battery 40 .

[0049] Specifically, the dome cover 42 can move along the moving axis direction of the base shell 41. A maintenance groove 411 is opened on the base shell 41. A baffle is fixed on the maintenance groove 411 by fasteners. The maintenance groove 411 is used to inspect, repair and replace the battery 40 by moving the dome cover 42 to expose the battery 40 for maintenance and inspection. When fixing is required, the dome cover 42 is driven to move toward the bottom of the base shell 41 so that the push ring 403 fits the battery 40 and compresses the spring 402 to fix the battery 40. A fan 401 facing the gathering pipe 43 is arranged on the top of the dome cover 42 to assist in sucking the airflow in the dome cover 42.

[0050] During maintenance, the battery 40 is fixedly shielded or unlocked and exposed by moving the dome cover 42. When the lamp post 1 is set in the green belt, the low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then, the temperature in the dome cover 42 rises with the use of the battery 40, and the heated air flow is discharged along the gathering pipe 43 to suck the wet and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue to heat the photovoltaic The plate 31 is cooled. At this time, the moisture in the moisture is reduced and discharged with the gas in the dome cover 42, which will suck the airflow in the cooling chamber 321, so that the airflow flows to the bottom of the dome cover 42 along the return channel for circulation. When the lamp post 1 is set on a highway (asphalt or plastic road), the interlayer part and the dome cover 42 float up due to heating, increasing the air supply to the cooling chamber 321, so as to squeeze the cooling chamber 321, and squeeze the gas in the cooling chamber 321 with a lower temperature than that at the bottom into the dome cover 42 along the return channel for cooling.

[0051] As an embodiment provided by the present invention, a sliding gear ring 431 is provided on the gathering pipe 43, and a concave gear ring 123 is provided on the mixing channel 12. The dome cover 42 is driven to move to drive the concave gear ring 123 and the sliding gear ring 431 to couple, so that the gathering pipe 43 and the mixing channel 12 are connected and the suction channel is closed.

[0052] Specifically, the gathering tube 43 can move with the movement of the dome cover 42. A concave gear ring 123 is provided on the inner wall of the mixing channel 12, and a sliding gear ring 431 is provided on the gathering tube 43. The sliding gear ring 431 and the concave gear ring 123 complement each other. When the weather is relatively cold, the storage capacity of the battery 40 will drop significantly as the temperature decreases. To avoid this situation, the dome cover 42 is moved to couple and overlap the concave gear ring 123 and the sliding gear ring 431, the gathering tube 43 and the mixing channel 12 are connected, and the suction channel is closed. At this time, the heat generated by the battery 40 will rise along the mixing channel 12 into the cooling chamber 321, and then return to the dome cover 42 along the return channel for heat circulation to maintain the temperature of the battery 40 and reduce the impact of cooling on the battery 40.

[0053] During maintenance, the battery 40 is fixedly shielded or unlocked and exposed by moving the dome cover 42. When the lamp post 1 is set in the green belt, the low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then, the temperature in the dome cover 42 is increased with the use of the battery 40, and the heated air flow is discharged along the gathering pipe 43 to suck the wet and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue cooling the photovoltaic panel 31. At this time, the moisture in the moisture is reduced, and it is discharged with the gas in the dome cover 42, which will suck the cooling chamber 32 1, so that the airflow flows along the return channel to the bottom of the dome cover 42 for circulation. When the lamp post 1 is set on a highway (asphalt or plastic road), the interlayer part and the dome cover 42 float up due to heating, increasing the air supply to the cooling chamber 321 to squeeze the cooling chamber 321, and squeeze the gas in the cooling chamber 321 with a lower temperature than that at the bottom into the dome cover 42 along the return channel for cooling. When the temperature is low, the dome cover 42 is moved to couple and overlap the concave gear ring 123 and the sliding gear ring 431, and the heat generated by the battery 40 will rise along the mixing channel 12 and enter the cooling chamber 321, and then return to the dome cover 42 along the return channel for heat circulation.

[0054] As an embodiment provided by the present invention, a folding ring 422 facing the base shell 41 is provided on the dome cover 42, and the dome cover 42 is assembled at the following three stations:

[0055] First station: the folding ring 422 is completely compressed as the dome cover 42 moves, and the suction channel is closed;

[0056] Second station: the folding ring 422 moves with the dome cover 42 and is semi-compressed, and the suction channel is open;

[0057] The third station: the folding ring 422 moves with the dome cover 42 without compression, and the battery 40 is unlocked.

[0058] Specifically, when performing maintenance, the dome cover 42 is moved along the base shell 41 toward the top of the lamp post 1 and switched to the third workstation. At this time, the battery 40 is exposed and unlocked at the same time, so as to facilitate replacement and maintenance operations. When the weather is hot and the battery 40 needs to be cooled, the dome cover 42 is moved along the base shell 41 toward the bottom of the lamp post 1 and switched to the second workstation. At this time, the dome cover 42 fixes the battery 40 and makes the folding ring 422 semi-compressed as the dome cover 42 moves, so that the suction channel is open to draw in external airflow for cooling. When the weather temperature is low, the dome cover 42 continues to move along the base shell 41 toward the bottom of the lamp post 1 and switches to the first workstation. The folding ring 422 is fully compressed as the dome cover 42 moves. At this time, the suction channel is closed and the gathering pipe 43 and the mixing channel 12 are connected to circulate the heat flow.

[0059] During maintenance, the dome cover 42 is moved along the base shell 41 to the top of the lamp post 1 and switched to the third station. At this time, the battery 40 is exposed and unlocked. When the weather is hot, the dome cover 42 is moved along the base shell 41 to the bottom of the lamp post 1 and switched to the second station. The dome cover 42 fixes the battery 40 and makes the folding ring 422 semi-compressed as the dome cover 42 moves, so that the suction channel is open. When the lamp post 1 is set in a green belt, the low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then, the temperature in the dome cover 42 rises with the use of the battery 40, and the heated airflow is discharged along the gathering pipe 43 to suck the humid and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue cooling the photovoltaic panel 31. However, at this time, the moisture in the moisture is reduced, and it is discharged with the gas in the dome cover 42, which will suck the airflow in the cooling chamber 321, so that the airflow flows to the bottom of the dome cover 42 along the return channel for circulation. When the lamp post 1 is set on a highway (asphalt or plastic road), the interlayer part and the dome cover 42 float due to heating, increasing the air supply to the cooling chamber 321, so as to squeeze the cooling chamber 321, and squeeze the gas in the cooling chamber 321 with a lower temperature than that at the bottom into the dome cover 42 along the return channel for cooling. When the temperature is low, the dome cover 42 continues to move along the base shell 41 toward the bottom of the lamp post 1, and switches to the first working position. The dome cover 42 is moved to couple and overlap the concave gear ring 123 and the sliding gear ring 431. The heat generated by the battery 40 will rise along the mixing channel 12 and enter the cooling chamber 321, and then return to the dome cover 42 along the return channel for heat circulation.

[0060] As an embodiment provided by the present invention, an air intake assembly 5 is arranged in a circumferential array on the base shell 41, and the air intake assembly 5 includes a plurality of reverse-top air intake grooves 51, and the reverse-top air intake grooves 51 are driven to open or close.

[0061] Specifically, folding portions 511 are provided at both ends of the reverse-top air inlet groove 51, and the reverse-top air inlet groove 51 can be bent and sealed along the folding portions 511. An elastic mosquito-proof strip 52 is provided on the reverse-top air inlet groove 51, and the elastic mosquito-proof strip 52 prevents mosquitoes from entering the interlayer. At the same time, when the reverse-top air inlet groove 51 is switched to the first working position along with the dome cover 42, it is folded to increase the sealing ability through the elastic mosquito-proof strip 52, and the reverse-top air inlet groove 51 is sealed to disconnect the interlayer from the outside world, thereby achieving a heat preservation effect and further retaining the heat generated by the battery 40.

[0062] During maintenance, the dome cover 42 is moved along the base shell 41 to the top of the lamp post 1 and switched to the third station. At this time, the battery 40 is exposed and unlocked. When the weather is hot, the dome cover 42 is moved along the base shell 41 to the bottom of the lamp post 1 and switched to the second station. The dome cover 42 fixes the battery 40 and makes the folding ring 422 semi-compressed as the dome cover 42 moves, so that the suction channel is open. When the lamp post 1 is set in the green belt, the low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then, the temperature in the dome cover 42 rises with the use of the battery 40, and the heated air flow is discharged along the gathering pipe 43 to suck the humid and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue cooling the photovoltaic panel 31. At this time, the moisture in the moisture is reduced, and the dome cover 4 2 is discharged, which will suck the airflow in the cooling chamber 321, so that the airflow flows along the return channel to the bottom of the dome cover 42 for circulation. When the lamp post 1 is set on a highway (asphalt or plastic road), the interlayer part and the dome cover 42 will float due to heating, increasing the air supply to the cooling chamber 321, so as to squeeze the cooling chamber 321, and squeeze the gas in the cooling chamber 321 with a lower temperature than that at the bottom into the dome cover 42 along the return channel for cooling. When the temperature is relatively low, the dome cover 42 is continued to move along the base shell 41 toward the bottom of the lamp post 1, and switched to the first working position. The dome cover 42 is moved to couple and overlap the concave gear ring 123 and the sliding gear ring 431, and at the same time, the reverse top air inlet groove 51 is bent along the folding portion 511, and the reverse top air inlet groove 51 is sealed to disconnect the interlayer part from the outside. The heat generated by the battery 40 will rise along the mixing channel 12 and enter the cooling chamber 321, and then return to the dome cover 42 along the return channel for heat circulation.

[0063] As the optimal embodiment provided by the present invention, a switching component 6 is arranged on the base shell 41, and the switching component 6 includes a rotating roller 612 rotatably connected to the base shell 41, and an arc-shaped strip 61 is arranged on the rotating roller 612 to fit the reverse top air inlet groove 51, and connecting strips 611 are arranged between the arc-shaped strips 61, and the rotating roller 612 is driven to rotate and push against the dome cover 42.

[0064] Specifically, a threaded rod 62 is threadedly connected to the base shell 41, and a rotating roller 612 is fitted onto the heat dissipation fins 421 on the dome cover 42. When it is necessary to switch the work station, the rotating threaded rod 62 pushes one of the arc strips 61 to flip it, so that the flipped rotating roller 612 fits the heat dissipation fins 421 to drive the dome cover 42 to move toward the bottom of the base shell 41, so as to realize the switching of the work station.

[0065] During maintenance, the dome cover 42 is moved along the base shell 41 to the top of the lamp post 1 and switched to the third station. At this time, the battery 40 is exposed and unlocked. When the weather is hot, the dome cover 42 is moved along the base shell 41 to the bottom of the lamp post 1 and switched to the second station. The dome cover 42 fixes the battery 40 and makes the folding ring 422 semi-compressed as the dome cover 42 moves, so that the suction channel is open. When the lamp post 1 is set in the green belt, the low-temperature moisture in the green belt will enter the interlayer part along the through groove, and cool the battery 40 in the dome cover 42 by contacting the heat dissipation fins 421. Then, the temperature in the dome cover 42 rises with the use of the battery 40, and the heated air flow is discharged along the gathering pipe 43 to suck the humid and cold gas in the interlayer part, mix it in the mixing channel 12, and input it into the cooling chamber 321 to continue cooling the photovoltaic panel 31. At this time, the moisture in the moisture is reduced, and the dome cover 4 2 is discharged, which will suck the airflow in the cooling chamber 321, so that the airflow flows along the return channel to the bottom of the dome cover 42 for circulation. When the lamp post 1 is set on a highway (asphalt or plastic road), the interlayer part and the dome cover 42 will float due to heating, increasing the air supply to the cooling chamber 321, so as to squeeze the cooling chamber 321, and squeeze the gas in the cooling chamber 321 with a lower temperature than that at the bottom into the dome cover 42 along the return channel for cooling. When the temperature is relatively low, the dome cover 42 is continued to move along the base shell 41 toward the bottom of the lamp post 1, and switched to the first working position. The dome cover 42 is moved to couple and overlap the concave gear ring 123 and the sliding gear ring 431, and at the same time, the reverse top air inlet groove 51 is bent along the folding portion 511, and the reverse top air inlet groove 51 is sealed to disconnect the interlayer part from the outside. The heat generated by the battery 40 will rise along the mixing channel 12 and enter the cooling chamber 321, and then return to the dome cover 42 along the return channel for heat circulation.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
