[0008] Preferably, the output end of the single-axis motor is coaxially and fixedly connected to the driving pulley in the pulley assembly. The driving pulley and the driven pulley in the pulley assembly are coaxially and fixedly connected to two sets of transmission rods, respectively.

[0009] Preferably, the support plate has a square groove in the middle that is slidably connected to the protective shell, and a storage groove is vertically provided at one end of the support plate near the fireproof component. The support plate has a storage shell near the storage groove and on the outside of the fireproof component.

[0010] Preferably, the shielding component includes two sets of shielding frames that are slidably connected to the top sides of the protective shell, the protective shell is connected to an adjusting component for adjusting the horizontal position of the two sets of shielding frames, the shielding frames are connected to a branch pipe connected to the fireproof component, and the two sets of shielding frames are respectively connected to three sets of corrugated pipes that are fixedly connected to and communicate with the branch pipes.

[0011] Preferably, the adjusting component includes two sets of bidirectional screws rotatably connected to the front and rear sides of the protective shell, respectively. The two sets of bidirectional screws are threadedly connected to two sets of shielding frames, and the two sets of bellows are located outside the two sets of bidirectional screws. A dual-axis motor is fixedly connected to the outside of the protective shell, and a set of second bevel gear assemblies for driving the bidirectional screws is connected to the front and rear sides of the dual-axis motor, respectively.

[0014] Beneficial effects

[0015] This invention provides a fire-monitoring, self-power-off intelligent charging pile. Compared with existing technologies, it has the following advantages:

[0016] (1) The fire-prevention monitoring self-power-off smart charging pile, by setting protective components inside the device, after detecting that the temperature of the main body of the charging pile is close to the fire temperature and cutting off the power under the control of the smart controller, allows the single-axis motor to cooperate with the pulley assembly, two sets of transmission rods, four sets of first bevel gear assemblies, and one-way screws to achieve side shielding protection of the main body of the charging pile by adjusting the vertical height of the protective shell and shielding components. The dual-axis motor, two sets of second bevel gear assemblies, and two-way screws cooperate to achieve upper shielding protection of the main body of the charging pile by adjusting the distance between the two sets of shielding frames, so that a relatively closed protective space is formed on the outside of the main body of the charging pile, reducing its contact range with the outside world, playing a protective role against the outside world, which helps subsequent fire extinguishing operations and reduces safety hazards.

[0017] (2) The fire-prevention monitoring self-power-off smart charging pile is equipped with a corrugated pipe, a protective pipe and a protective tube inside the device. The protective pipe and the corrugated pipe work together to protect the outside of the two sets of bidirectional screws from dust, while the protective tube protects the unidirectional screws from dust. The protective pipe, the protective tube and the corrugated pipe are all elastic and will deform accordingly during the traction process, so as to prevent the unidirectional screws and bidirectional screws from being directly exposed to the external environment, and not affect the adjustment of the unidirectional screws and bidirectional screws on the protective shell and the shielding frame.

[0018] (3) The fire-prevention monitoring self-power-off intelligent charging pile has fireproof components installed inside the device. The fireproof components are installed with a mounting plate and a support frame to facilitate the access of electromagnetic fire extinguishers. The connector body and nut are fitted together to facilitate the disassembly and installation between the extension tube and the branch tube, which makes it easier for users to replace electromagnetic fire extinguishers. The intelligent controller can then activate two sets of electromagnetic fire extinguishers to spray dry powder through the extension tube, connector body, branch tube, corrugated tube, and the discharge trough end of the shielding frame into the surface of the charging pile body inside the protective shell. This facilitates the user's disassembly and replacement of fire extinguishing equipment. In conjunction with the shielding frame, it can quickly extinguish fires by spraying dry powder onto the charging pile body in the corresponding protected space. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] refer to Figures 1-6 The present invention provides the following three technical solutions:

[0028] First implementation: A fire-monitoring self-power-off smart charging pile includes a charging pile body 1. The charging pile body 1 is connected to a processing component for fire monitoring. The processing component includes: several sets of temperature sensors 2, which are fixedly connected to the side of the charging pile body 1 for temperature detection; and a protective component 3, which is installed at the bottom of the charging pile body 1 for power-off protection. The protective component 3 includes a support base 33 fixedly connected to the bottom of the charging pile body 1. The support base 33 has a built-in smart controller that is electrically connected to the charging pile body 1 and the temperature sensors 2 and is used for power-off control. A support shell 32 is fixedly connected to the bottom of the support base 33. A support plate 31 is fixedly connected to the top of the support base 33 near the bottom of the charging pile body 1. A protective shell 35 is slidably connected to the inner side of the support base 33 near the outer side of the charging pile body 1. A lifting component 34 for height adjustment of the protective shell 35 is provided at the bottom of the support shell 32. A shielding component 36 for shielding the top of the charging pile body 1 is installed on the top of the lifting component 34. Two sets of fireproof components 37 for fire extinguishing treatment in conjunction with the shielding component 36 are installed on the rear side of the support plate 31.

[0029] The lifting component 34 includes a single-axis motor 341 fixedly connected to the bottom of the support shell 32. The output end of the single-axis motor 341 is connected to a pulley assembly 342. The pulley assembly 342 is connected to a set of transmission rods 343 rotatably connected to the support shell 32 on both sides near the support base 33. The front and rear sides of the transmission rods 343 are respectively connected to a set of first bevel gear assemblies 344. The top of the first bevel gear assembly 344 is connected to a one-way screw 345 rotatably connected to the support shell 32. All four sets of one-way screws 345 are threadedly connected to the protective shell 35. The output end of the single-axis motor 341 is coaxially fixedly connected to the drive pulley in the pulley assembly 342. The drive pulley and driven pulley in the pulley assembly 342 are coaxially fixedly connected to the two sets of transmission rods 343. The transmission rods 343 are coaxially fixedly connected to the first drive bevel gear in the first bevel gear assembly 344. The first driven bevel gear in the first bevel gear assembly 344 is coaxially fixedly connected to the one-way screw 345.

[0030] The support plate 31 has a square groove in the middle that is slidably connected to the protective shell 35. The end of the support plate 31 near the fireproof component 37 has a vertically penetrating storage groove. The support plate 31 has a storage shell near the storage groove and the outside of the fireproof component 37. The shielding component 36 includes two sets of shielding frames 361 that are slidably connected to the top sides of the protective shell 35. The protective shell 35 is connected to an adjusting component 362 for adjusting the horizontal position of the two sets of shielding frames 361. The shielding frames 361 are connected to a branch pipe 363 that is connected to the fireproof component 37. The two sets of shielding frames 361 are respectively connected to three sets of corrugated pipes 364 that are fixedly connected to and communicate with the branch pipes 363.

[0031] Adjusting component 362 includes two sets of bidirectional screws 3623 rotatably connected to the front and rear sides of the protective shell 35, respectively. The two sets of bidirectional screws 3623 are threadedly connected to two sets of shielding frames 361. Two sets of bellows 364 are located outside the two sets of bidirectional screws 3623. A dual-axis motor 3621 is fixedly connected to the outside of the protective shell 35. A second bevel gear assembly 3622 for driving the bidirectional screws 3623 is connected to the front and rear sides of the dual-axis motor 3621, respectively. The output end of the dual-axis motor 3621 is coaxially and fixedly connected to the second driving bevel gear within the second bevel gear assembly 3622. The second driven bevel gear within the second bevel gear assembly 3622 is coaxially and fixedly connected to the bidirectional screws 3623. After detecting that the temperature of the charging pile body 1 is close to the ignition temperature and the power is cut off under the control of the intelligent controller, the single-axis motor 341, pulley assembly 342, two sets of transmission rods 343, four sets of first bevel gear assemblies 344, and one-way screw 345 cooperate to adjust the vertical height of the protective shell 35 and the shielding part 36, so that the protective shell 35 shields and protects the side of the charging pile body 1. Then, the dual-axis motor 3621, two sets of second bevel gear assemblies 3622, and two-way screw 3623 cooperate to adjust the distance between the two sets of shielding frames 361 to shield and protect the upper side of the charging pile body 1, reduce the contact area between the charging pile body 1 and the outside world, facilitate subsequent fire extinguishing operations, and reduce safety hazards.

[0032] The main difference between the second implementation method and the first implementation method is that:

[0033] Four sets of protective tubes for protecting the bidirectional screws 3623 are fixedly connected to the inner wall of the protective shell 35 near the front and rear sides of the two sets of corrugated tubes 364 respectively. Eight sets of protective tubes fixedly connected to the protective shell 35 are fixedly connected to the outer side of the support shell 32 near the four sets of unidirectional screws 345. The protective tubes and corrugated tubes 364 are made of the same material, namely silicone rubber, which is fire resistant. The protective shell 35 is fixedly connected to the outer side of the dual-shaft motor 3621 and the second bevel gear assembly 3622. The bottom of the shielding frame 361 is provided with a discharge chute for dry powder spraying near the charging pile body 1. The protective tubes and corrugated tubes 364 cooperate to protect the two sets of bidirectional screws 3623 from dust, while the protective tubes protect the unidirectional screws 345 from dust. The protective tubes, corrugated tubes and corrugated tubes 364 are all elastic and will deform accordingly during the traction process.

[0034] The main difference between the third and second implementation methods is that:

[0035] Fireproof component 37 includes a mounting plate 371 that fits against the upper end of support plate 31. The mounting plate 371 has a set of bolts along its edge, which are threaded onto the support plate 31. A support frame 372 is fixedly connected to the bottom of the mounting plate 371, and the bottom of the support frame 372 fits against the storage shell. An electromagnetic fire extinguisher 373 is slidably connected to the support frame 372 near the upper side of the mounting plate 371. The mounting plate 371 has a slot that matches the electromagnetic fire extinguisher 373. There is a space between the bottom of the mounting plate 371 and the electromagnetic fire extinguisher 373 for storage and retrieval. A single-axis motor 341, a dual-axis motor 3621, and the electromagnetic fire extinguisher 373 are all electrically connected to an intelligent controller. An extension tube 374 is fixedly connected to the discharge end of the electromagnetic fire extinguisher 373, and the extension tube 374 is located away from the electromagnetic fire extinguisher. One end of the fire extinguisher 373 is fixedly connected to a connector body 375 that is connected to the shield 36. The rear side of the branch pipe 363 is fixedly connected to a nut that is threadedly connected to the connector body 375. A retainer is provided between the connector body 375 and the nut. The mounting plate 371 cooperates with the support frame 372 to facilitate the storage and retrieval of the electromagnetic fire extinguisher 373. The connector body 375 cooperates with the nut to facilitate the disassembly and installation between the extension tube 374 and the branch pipe 363, thereby facilitating the user to replace the electromagnetic fire extinguisher 373. The intelligent controller activates two sets of electromagnetic fire extinguishers 373 to spray dry powder through the extension tube 374, connector body 375, branch pipe 363, corrugated pipe 364, and the discharge chute end of the shield frame 361 into the surface of the charging pile body 1 inside the protective shell 35 to achieve fireproofing.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During use, the user monitors the temperature of the charging pile body 1 through the temperature sensor 2 and continuously feeds back the data to the intelligent controller inside the support base 33. The charging pile body 1 then charges the corresponding vehicle. The charging pile body 1, temperature sensor 2, and intelligent controller are all existing technologies, so their internal structure and working principle will not be described in detail. When the temperature sensor 2 detects an abnormal temperature in the charging pile body 1, the intelligent controller stops supplying power to the charging pile body 1. Simultaneously, it starts the single-axis motor 341. The single-axis motor 341 provides power to the four sets of first bevel gear assemblies 344 through the pulley assembly 342 and two sets of transmission rods 343. The four sets of first bevel gear assemblies 344 drive the four sets of one-way screws 345 to rotate. The four one-way screws 345 work together... The protective shell 35 and the shielding component 36 are moved vertically, so that the shielding frame 361 inside the shielding component 36 is aligned with the outer edge of the charging pile body 1. After the shielding frame 361 is raised to a suitable height, the dual-axis motor 3621 is started. The dual-axis motor 3621 drives the two sets of shielding frames 361 to move in opposite directions through two sets of second bevel gear assemblies 3622. During the above adjustment process, the corrugated pipe 364 is extended accordingly. After the distance between the two sets of shielding frames 361 can no longer be shortened, the dual-axis motor 3621 is turned off and the intelligent controller is activated to activate the two sets of electromagnetic fire extinguishers 373. The electromagnetic fire extinguishers 373 spray dry powder into the surface of the charging pile body 1 inside the protective shell 35 through the extension pipe 374, connector body 375, branch pipe 363, corrugated pipe 364, and the discharge chute end of the shielding frame 361, thereby achieving fireproofing treatment.
