Description

Technical Field

[0001] This invention relates to the field of new energy charging piles, and in particular to a cable-laying mechanism for charging piles of electric equipment in thermal power plants. Background Technology

[0002] A thermal power plant, or coal-fired power plant for short, is a factory that uses combustible materials (such as coal) as fuel to produce electricity. Its basic production process is as follows: fuel burns to heat water and generate steam, converting the chemical energy of the fuel into heat energy. The steam pressure drives a turbine to rotate, converting the heat energy into mechanical energy. The turbine then drives a generator to rotate, converting the mechanical energy into electrical energy. Thermal power plants typically use electric forklifts and other electric equipment to move goods. To meet usage demands, existing charging stations often use long charging cables, which are frequently coiled on the ground or rolled up on the outside of the charging station after use. These cables are prone to shortening their lifespan due to vehicle pressure or environmental factors, posing a risk of electrical leakage. Furthermore, the power equipment generates significant heat during vehicle charging. Current technology typically uses cooling fans to dissipate heat, but in thermal power plants, the cooling channels on the charging stations can become blocked due to the external environment, affecting cooling efficiency. Summary of the Invention

Detailed Implementation

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 Reference Figure 1 , 2 This is the first embodiment of the present invention, which provides a cable-laying mechanism for charging piles of electric equipment in thermal power plants.

[0020] The charging pile assembly 100 includes a charging pile housing 101. A power supply device 104 is fixedly installed on the bottom inner side of the charging pile housing 101. A cooling fan 109 is provided on one side of the power supply device 104. A charging cable 105 is fixedly installed on one end of the power supply device 104.

A door 102 is hinged to the side of the charging pile housing 101.

[0021] Specifically, the power supply device 104 is connected to the main power supply unit of the charging pile, and the cooling fan 109 is electrically connected to the power supply device 104 through a wire. When the user uses the charging gun 106 to charge the electric vehicle, the cooling fan 109 starts to run to cool the power supply device 104.

[0022] A connecting block 107 is fixedly connected inside the charging pile box 101. A guide ring 108 is fixedly connected to one side of the connecting block 107, and the charging cable 105 passes through and is disposed inside the guide ring 108.

[0023] Specifically, inside the charging pile housing 101, the charging cable 105 passes through the guide ring 108. The charging cable 105 also passes through the charging pile housing 101 and connects to the charging gun 106. The guide ring 108 can guide the charging cable 105 to prevent the charging cable 105 from bending and being damaged.

[0024] Example 2 Reference Figure 2 , 4 5 and 6 are the second embodiment of the present invention, which is based on the previous embodiment.

[0025] The unwinding and rewinding assembly includes a first rotating shaft 201 and a locking structure 205. A take-up roller 202 is fixedly connected to the surface of the first rotating shaft 201. Limiting discs 203 are provided at the top and bottom of the take-up roller 202. A torsion spring 204 is provided at the lower end of the first rotating shaft 201. A charging cable 105 is wound around the surface of the take-up roller 202. A locking block 205f is movably provided at the end of the locking structure 205. A ratchet 201a is fixedly connected to the surface of the first rotating shaft 201. The end of the locking block 205f engages with the ratchet 201a. The locking structure 205 includes a U-shaped part 205a fixedly connected to the surface of the charging pile housing 101. The charging gun 106 can be stored inside the U-shaped part 205a. One end of the U-shaped part 205a is fixedly connected to a mounting box 205b. 5b is fixedly connected to the charging pile box 101 and the U-shaped part 205a. The mounting plate 205d is fixedly connected to the middle of the inner side of the mounting box 205b. The reset spring 205e is fixedly connected to the left side of the mounting plate 205d. The movable block 205c is fixedly connected to the left side of the reset spring 205e. Mounting blocks 205c-2 are symmetrically arranged on both sides of the movable block 205c. The drive rod 205c-3 is fixedly connected to the right side of the mounting block 205c-2. The end of the drive rod 205c-3 is hinged to the hinge rod 205c-4. The end of the hinge rod 205c-4 is hinged to the guide wheel 205c-5. The left side of the locking block 205f is fixedly connected to the rectangular frame 205f-1. A set of guide wheels 205c-5 are slidably connected to the inner side of the rectangular frame 205f-1.

[0026] Specifically, the U-shaped component 205a is fixedly installed inside the shield 103 and is fixedly connected to the surface of the charging pile housing 101, so that the charging gun 106 can be stored inside the U-shaped component 205a. Together with the shield 103, it can prevent the charging gun 106 from being damaged by external factors. When the electric vehicle is fully charged, the charging gun 106 is pressed against the movable block 205c in the locking structure 205. When the movable block 205c moves, it can drive the mounting blocks 205c-2 on both sides, causing the drive rod 205c-3 to move. The drive rod 205c-3 can drive the hinge rod 205c-4 to move. The hinge rod 205c-4 can drive the guide wheel 205c-5 to slide inside the rectangular frame 205f-1, thereby... The structure allows the rectangular frame 205f-1 to shift to the left inside the mounting box 205b, thereby disengaging the locking block 205f from the ratchet 201a. Under the action of the torsion spring 204, the first rotating shaft 201 will rotate in the opposite direction, driving the winding roller 202 to wind up the charging cable 105. This allows the charging cable 105 exposed on the outside of the charging pile box 101 to be wound into the inside of the charging pile box 101. After winding, the charging gun 106 is released. Under the action of the return spring 205e, the movable block 205c will cooperate with the drive rod 205c-3, the hinge rod 205c-4, the guide wheel 205c-5, and the rectangular frame 205f-1 to drive the locking block 205f to shift to the right, so that the locking block 205f can re-engage with the ratchet 201a.

[0027] A set of mounting grooves 205a-1 are symmetrically opened on the inner side of the U-shaped part 205a. An elastic spring 205a-2 is fixedly connected inside the mounting groove 205a-1, and a stop block 205a-3 is fixedly connected to the end of the elastic spring 205a-2. A rectangular hole 205a-4 is opened on the inner side of the U-shaped part 205a. A movable block 205c is disposed through the inner side of the rectangular hole 205a-4. A limit plate 205c-1 is fixedly connected to the surface of the movable block 205c. A set of rod holes 205d-1 are symmetrically opened on the surface of the mounting plate 205d. A drive rod 205c-3 is movably connected inside the rod hole 205d-1. A clearance hole 205b-1 is opened at the end of the mounting box 205b away from the U-shaped part 205a. A locking block 205f is disposed through the clearance hole 205b-1. The end of the locking block 205f passes through the clearance hole 205b-1 and engages with the ratchet 201a.

[0028] Specifically, under the action of the elastic spring 205a-2, a set of stop blocks 205a-3 can prevent the charging gun 106 from falling off the inside of the U-shaped part 205a. By opening the rectangular hole 205a-4, the movable block 205c can be pressed more conveniently, which is convenient for winding the charging cable 105. By setting the rod hole 205d-1, the drive rod 205c-3 can be guided so that the drive rod 205c-3 can move in parallel. By setting the clearance hole 205b-1, the locking block 205f can be engaged with the ratchet 201a.

[0029] Example 3 Reference Figure 2 and 3 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0030] The cleaning assembly 300 includes a fixed plate 301, a second rotating shaft 302 rotatably connected to the inner side of the fixed plate 301, a drive structure 304 at one end of the second rotating shaft 302, a rack plate 305 on the inner side of the drive structure 304, a fixing strip 306 fixedly connected to the bottom of the rack plate 305, a cleaning brush 306b on the surface of the fixing strip 306, and a heat dissipation groove 101a on the back of the charging pile housing 101, with a dust filter 10 installed inside the heat dissipation groove 101a. 1b, the cleaning brush 306b is attached to the dust filter 101b. A set of rectangular vertical plates 307 are fixedly connected to the inner wall of the charging pile box 101 on both sides of the heat dissipation groove 101a. The fixing strip 306 is slidably connected between the set of rectangular vertical plates 307. A guide groove 307a is opened on the side of the rectangular vertical plate 307 near the fixing strip 306. Guide blocks 306a are fixedly connected to both sides of the fixing strip 306, and the guide blocks 306a are slidably connected inside the guide groove 307a.

[0031] Specifically, the drive structure 304 can drive the rack plate 305 to reciprocate up and down, so that the rack plate 305 drives the fixed bar 306 to move synchronously. The fixed bar 306 is slidably connected between a set of rectangular vertical plates 307, and slides in the guide groove 307a with the guide block 306a, so that the fixed bar 306 can slide smoothly. The cleaning brush 306b set on the fixed bar 306 can clean the dust and debris on the dust filter 101b, so as to cooperate with the cooling fan 109 to perform better heat dissipation operation on the power supply device 104.

[0032] A drive bevel gear 201b is fixedly connected to the upper surface of the first rotating shaft 201, and a driven bevel gear 303 is fixedly connected to the end of the second rotating shaft 302 away from the drive structure 304. The drive bevel gear 201b and the driven bevel gear 303 are meshed and connected, and the basic parameters of the drive bevel gear 201b and the driven bevel gear 303 are the same.

[0033] Specifically, by setting the driving bevel gear 201b and driven bevel gear 303 with identical basic parameters, when the charging gun 106 is pulled to make the charging cable 105 drive the first rotating shaft 201 to rotate, the driving bevel gear 201b can drive the meshing driven bevel gear 303 to rotate together, so that the drive structure 304 can operate simultaneously.

[0034] The drive structure 304 includes a drive gear 304a fixedly connected to the end of the second rotating shaft 302. A first driven shaft 304b and a second driven shaft 304c are rotatably connected to both sides of the second rotating shaft 302 via the surface of the fixing plate 301. A first driven gear 304b-1 is fixedly connected to the surface of the first driven shaft 304b, and a first fixing ring 304b-2 is fixedly connected to the end of the first driven shaft 304b. A first semi-circular gear 304b-3 is fixedly connected to the surface of the first fixing ring 304b-2. A second driven gear 304c-1 is fixedly connected to the surface of the second driven shaft 304c, and a second fixing ring 304c-2 is fixedly connected to the end of the second driven shaft 304c. A second semi-circular gear 304c-3 is fixedly connected to the surface of the second fixing ring 304c-2. The first driven gear 304b-1 and the second driven gear 304c-1 are located on either side of the drive gear 304a. On one side, the drive gear 304a meshes with the first driven gear 304b-1 and the second driven gear 304c-1, with the first driven gear 304b-1 and the second driven gear 304c-1 rotating in the same direction, and the drive gear 304a rotating in the opposite direction to the first driven gear 304b-1 and the second driven gear 304c-1. The rack plate 305 is located between the first semi-circular gear 304b-3 and the second semi-circular gear. Between 304c-3, and both the first semi-circular gear 304b-3 and the second semi-circular gear 304c-3 can mesh with the rack plate 305. The first semi-circular gear 304b-3 and the second semi-circular gear 304c-3 are completely identical, and the number of teeth of the first semi-circular gear 304b-3 and the second semi-circular gear 304c-3 matches the number of teeth on both sides of the rack plate 305. Support blocks 305a are provided on both sides of the rack plate 305 at the upper and lower ends of the rack.

[0035] Specifically, driven by the driving bevel gear 201b and the driven bevel gear 303, the driving gear 304a on the second rotating shaft 302 rotates in the same direction as the driven bevel gear 303. The driving gear 304a meshes with the first driven gear 304b-1 and the second driven gear 304c-1, which can drive the first driven gear 304b-1 and the second driven gear 304c-1 to rotate in the opposite direction to the driving gear 304a. This causes the first semi-circular gear 304b-3 and the second semi-circular gear 304c-3 to mesh with the rack plate 305 in sequence. When the first driven gear 304b-1 and the second driven gear 304c-1 rotate clockwise, the end of the second semi-circular gear 304c-3 engages with the rack plate 305. The support block 305a makes contact first, and then the rack plate 305 rises through the second semi-circular gear 304c-3. When the rack plate 305 rises to a certain extent, the second semi-circular gear 304c-3 disengages from the rack plate 305. At the same time, the end of the first semi-circular gear 304b-3 contacts the support block 305a, and the rack plate 305 falls through the first semi-circular gear 304b-3. When the first semi-circular gear 304b-3 is engaged with the rack plate 305, the second semi-circular gear 304c-3 will not contact the rack plate 305. When the first semi-circular gear 304b-3 disengages from the rack plate 305, the second semi-circular gear 304c-3 contacts the rack plate 305 and engages with it.

[0036] When using this device, pulling the charging cable 105 causes the take-up roller 202 to rotate the first rotating shaft 201 clockwise, and the torsion spring 204 stores energy. The locking block 205f and ratchet 201a prevent the first rotating shaft 201 from rotating counterclockwise. The driving bevel gear 201b on the first rotating shaft 201 meshes with the driven bevel gear 303 on the second rotating shaft 302, thereby driving the second rotating shaft 302 to rotate. This causes the driving gear 304a to sequentially drive the first driven gear 304b-1 and the second driven gear 304c-1 to rotate. When the first driven gear 304b-1 and the second driven gear 304c-1 rotate clockwise, the rack plate 305 rises through the second semi-circular gear 304c-3, and the rack plate 305 rises through the first semi-circular gear 304c-3. 4b-3 causes the rack plate 305 to descend, and when the first semi-circular gear 304b-3 meshes with the rack plate 305, the second semi-circular gear 304c-3 will not contact the rack plate 305. When the first semi-circular gear 304b-3 disengages from the rack plate 305, the second semi-circular gear 304c-3 contacts and meshes with the rack plate 305, thereby realizing the up-and-down reciprocating motion of the cleaning brush 306b, which can clean the dust filter 101b. Furthermore, when the charging gun 106 is connected to the electric vehicle charging port, the power supply device 104 charges via the charging cable 105, and simultaneously the cooling fan 109 starts running, dissipating the heat generated by the power supply device 104 through the heat dissipation slot 101a, thus providing... To effectively improve the heat dissipation of the power supply device 104, after charging is completed, the user can retract the handle of the charging gun 106 into the inside of a set of stops 205a-3, causing the rear end of the charging gun 106 to press against the movable block 205c. When the movable block 205c moves, it can cause the rectangular frame 205f-1 to shift to the left via the drive rod 205c-3, the hinge rod 205c-4, and the guide wheel 205c-5, thereby causing the locking block 205f to disengage from the surface of the ratchet 201a. Under the action of the torsion spring 204, the first rotating shaft 201 rotates counterclockwise, driving the winding roller 202 to wind up the charging cable 105, so that the charging cable 105 is stored inside the charging pile box 101. Finally, the charging gun 106 is released, and the reset spring... Under the action of spring 205e, movable block 205c will return to its original position and, together with a set of stop blocks 205a-3, fix charging gun 106. Through the above structure, when charging cable 105 is needed, it can be pulled out from inside charging pile box 101 for easy use. After use, charging cable 105 can be stored inside charging pile box 101, which can ensure that charging cable 105 is not damaged by external factors, thus extending the service life of charging cable 105. In addition, during the use and storage of charging cable 105, the dust filter 101b can be cleaned by cleaning brush 306b to prevent the dust filter 101b from becoming clogged due to long-term uncleaning, which would affect heat dissipation efficiency.
