Description

Technical Field

[0001] The present invention belongs to the technical field of flexible charging piles, and in particular relates to a flexible charging pile and a flexible charging method thereof. Background Art

[0002] Flexible charging stack is an advanced charging technology. It brings together all or part of the charging modules of the electric vehicle charging station and dynamically allocates the charging modules according to the actual charging power required by the electric vehicle through the power distribution unit.

The flexible charging stack is mainly composed of a main machine and multiple auxiliary machines, and the multiple auxiliary machines are connected to the new energy vehicles to charge them. At present, when some flexible charging pile hosts are operating outdoors, a large amount of outdoor dust will come into contact with and adhere to the flexible charging pile. If the staff manually cleans it every day, it will undoubtedly increase the labor. If it is cleaned regularly, once poor heat dissipation occurs, the temperature of the charging equipment will increase, thereby increasing the loss of internal electronic components, generating additional heat, causing energy loss, and reducing charging efficiency.

[0007] Preferably, a sleeve rod is fixedly connected to the tube body of the two corrugated tubes near the top, and one end of the rod body of the two sleeve rods is fixedly connected to the inner wall of the electrical box door.

[0013] A flexible charging method for a flexible charging stack, the specific charging method process is as follows: S1. First, high-precision sensors installed in flexible charging equipment should be used to monitor the battery status, the operation of electric vehicles and the load of the power grid in real time. The sensors will obtain the remaining power and temperature information of the battery, and understand whether the electric vehicle is in normal operation and the current load carrying capacity of the power grid, so as to facilitate the subsequent adjustment of charging power and time. S2. Through the intelligent algorithm in the flexible charging device, a comprehensive analysis will be conducted based on the battery status, vehicle operation status and grid load conditions to adjust the charging power and time. If the battery temperature is too high, the intelligent algorithm will reduce the charging power to protect the battery; if the grid load is low and the vehicle battery allows fast charging, the algorithm will appropriately increase the charging power to achieve adaptive adjustment of the charging process. The above is a flexible charging method.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention starts the electric cylinder to move downward at a regular interval, thereby driving the telescopic plate and the convex groove plate to move downward together. The downwardly moving convex groove plate will stretch the corrugated tube fixed at one end, so that a negative pressure suction force is generated inside the tube body. Therefore, in the process of the convex groove plate moving downward, the dust attached to the surface of the heat dissipation mesh plate is sucked together through the bent suction tube and the suction bucket, so as to achieve the effect of suction while moving downward, and avoid excessive dust accumulation affecting the heat dissipation effect of the heat dissipation mesh plate. The one-way valves respectively installed on the bent suction tube and the straight pipeline are used to control the two to only allow one-way flow of gas, thereby realizing the working process described above.

[0015] In the process of the passive downward movement of the convex groove plate of the present invention, the rubber abutment plates installed on both sides of the top of the convex groove plate elastically press against the guardrail plate. As the convex groove plate continues to move downward, it will repeatedly slide and press against one end of each guardrail plate. The guardrail plate that is pushed will simultaneously stretch the connected elastic telescopic parts to cause it to deform. When there is no subsequent pressure force applied by the guardrail plate, the elastic telescopic parts can drive it to automatically reset. The pushed guardrail plate also drives the connected multiple through-hole brushes to pass through the heat dissipation mesh plate at the same time to make through holes for it, thereby preventing dust from covering its surface and reducing the heat dissipation effect. Therefore, the heat dissipation mesh plate used for the heat dissipation effect is cleaned by a double-layer cleaning method of clearing dust while making through holes. No manual operation is required during the entire cleaning process, thereby improving the efficiency of cleaning and heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0019] like Figures 1 to 7 As shown, the present invention provides a flexible charging stack, including a flexible charging stack body 1, an electric box door 11 is hinged in the inner wall of both ends of one side of the flexible charging stack body 1, a heat dissipation mesh plate 12 is fixedly connected in the inner wall of one end of the two electric box doors 11, and a heat dissipation cleaning part 2 is respectively provided on the two electric box doors 11, and the two heat dissipation cleaning parts 2 respectively include an electric cylinder 21 fixedly connected to the inner wall of both sides of the top of the flexible charging stack body 1, and the outer wall of the bottom end of the two electric cylinders 21 is movably sleeved with a telescopic plate 22, and a convex mesh plate 12 is hinged on one end of the two telescopic plates 22. The groove plates 23, the door panels on both sides of the two electrical box doors 11 are through-opened with rectangular grooves that can be fitted and slidably connected with the two convex groove plates 23 respectively, the bottom inner walls of the two groups of rectangular grooves are respectively fixedly connected with the outer walls on both sides of the bottom ends of the two convex groove plates 23 with telescopic folding plates 24, and the inner walls at the other ends of the two convex groove plates 23 are fixedly connected with drawers 27, which is convenient for sucking the dust attached to the corresponding heat dissipation mesh plate 12, and the two convex groove plates 23 are also provided with suction and dust collection structures, and elastic through-hole structures are respectively provided on one side of the two suction and dust collection structures.

[0020] The above scheme is adopted: the electric cylinder 21 is started to move downward regularly and regularly, thereby driving the telescopic plate 22 and the convex groove plate 23 to move downward together. The movement of the convex groove plate 23 will pull the telescopic folding plate 24 in the rectangular groove in real time to prevent dust from entering from the rectangular groove. The downward moving convex groove plate 23 will stretch the corrugated tube 25 fixed at one end, so that negative pressure suction force is generated inside the tube body, and the dust attached to the surface of the heat dissipation mesh plate 12 is sucked together through the bending suction tube 26 and the suction bucket 27, so as to achieve the effect of suction while moving downward. To prevent excessive dust accumulation from affecting the heat dissipation effect of the heat dissipation mesh plate 12, at the same time, during the passive downward movement of the convex groove plate 23, the rubber abutment plates 2301 installed on both sides of the top of the convex groove plate 23 elastically press against the railing 236. As the convex groove plate 23 continues to move downward, it will repeatedly slide and press against one end of each railing 236, and the pushed railing 236 will also drive the connected multiple through-hole brushes 237 to pass through the heat dissipation mesh plate 12 at the same time to make through holes for it, thereby preventing dust from covering its surface and reducing the heat dissipation effect.

[0021] The two suction ash collecting structures each include two bellows 25 fixedly connected to the outer walls on both sides of the top end of the convex groove plate 23, the bottom ends of the two bellows 25 are fixedly connected with bent suction pipes 26, and the other end pipe openings of the two bent suction pipes 26 are fixedly connected to the plates on both sides of one end of the draw bucket 27, the pipe bodies of the two bent suction pipes 26 are fixedly connected to the inner walls of the plates on both sides of the convex groove plate 23, the ends of the two bellows 25 near the top are fixedly connected with straight delivery pipes 28, and the pipe bodies of the two bent suction pipes 26 and the straight delivery pipes 28 are fixedly connected with a one-way valve 29.

[0022] The above scheme is adopted: the downward moving convex groove plate 23 will stretch the corrugated tube 25 fixed at one end, so that negative pressure suction force is generated inside the tube body. Therefore, in the process of the convex groove plate 23 moving downward, the dust attached to the surface of the heat dissipation mesh plate 12 is sucked together through the bent suction tube 26 and the suction bucket 27, so as to achieve the effect of suction while moving downward, and avoid excessive dust accumulation to affect the heat dissipation effect of the heat dissipation mesh plate 12. The one-way valves 29 respectively installed on the bent suction tube 26 and the straight pipe 28 are used to control the two to only allow one-way flow of gas.

[0023] A sleeve rod is fixedly connected to the tube body of the two bellows 25 near the top, and one end of the rod body of the two sleeve rods is fixedly connected to the inner wall of the electric box door 11. The other ends of the two straight conveying pipes 28 are fixedly connected with a dust box 230. The top outer walls of the two dust boxes 230 are fit-connected to the top inner wall of the flexible charging stack body 1, and a sealing cover 231 can be intermittently and tightly clamped in the inner wall of one end of the two dust boxes 230. Rubber abutment plates 2301 are also fixedly connected to the outer walls on both sides of the top of the convex groove plate 23, and two T-shaped sliders 232 are also fixedly connected to the inner wall of one end of the convex groove plate 23.

[0024] The above scheme is adopted: when the bellows 25 passively moves upward and contracts, the gas inside will be squeezed to produce squeezed gas, and then the pressurized gas will carry the sucked-in dust through the straight pipe 28 and enter the dust box 230 for unified collection, so as to facilitate the subsequent direct opening of the sealing cover 231 on the dust box 230 to uniformly clean the dust inside. In the process of the passive downward movement of the convex groove plate 23, it will specifically be limited and guided in translation in the T-shaped groove 234 correspondingly opened on the vertical plate 233 through the two T-shaped sliders 232 installed thereon, until the rubber abutment plates 2301 installed on both sides of the top of the convex groove plate 23 are elastically pressed against the railing 236.

[0025] The two elastic through-hole structures respectively include a vertical plate 233, and two T-shaped grooves 234 are provided on the outer wall of one end of the vertical plate 233, which can be slidably engaged with the two T-shaped sliders 232 respectively. A plurality of groups of elastic telescopic parts 235 are fixedly connected to the outer wall of the other end of the vertical plate 233, and a guard plate 236 is fixedly connected to the other end of each group of elastic telescopic parts 235, and a plurality of through-hole brushes 237 are fixedly connected to the other end of each guard plate 236, and each group of through-hole brushes 237 can be intermittently fitted and slidably connected to the heat dissipation mesh plate 12, and a plurality of support plates 238 are fixedly connected to the bottom end of the vertical plate 233, and the other end of each support plate 238 is fixedly connected to the inner wall of one end of the electrical box door 11.

[0026] The above scheme is adopted: as the convex groove plate 23 continues to move downward, it will repeatedly slide and press against one end of each baffle plate 236, so that the pushed baffle plate 236 will simultaneously stretch the connected elastic telescopic member 235 to cause it to deform, and when there is no subsequent pressure force applied by the baffle plate 236, the elastic telescopic member 235 can drive it to automatically reset, and the pushed baffle plate 236 also drives the connected multiple through-hole brushes 237 to pass through the heat dissipation mesh plate 12 at the same time to make through holes for it, so as to prevent dust from covering its surface and reducing the heat dissipation effect.

[0027] A flexible charging method for a flexible charging stack, the specific charging method process is as follows: S1. First, high-precision sensors installed in flexible charging equipment should be used to monitor the battery status, the operation of electric vehicles and the load of the power grid in real time. The sensors will obtain the remaining power and temperature information of the battery, and understand whether the electric vehicle is in normal operation and the current load carrying capacity of the power grid, so as to facilitate the subsequent adjustment of charging power and time. S2. Through the intelligent algorithm in the flexible charging device, a comprehensive analysis will be conducted based on the battery status, vehicle operation status and grid load conditions to adjust the charging power and time. If the battery temperature is too high, the intelligent algorithm will reduce the charging power to protect the battery; if the grid load is low and the vehicle battery allows fast charging, the algorithm will appropriately increase the charging power to achieve adaptive adjustment of the charging process. The above is a flexible charging method.

[0028] The working principle and use process of the present invention are as follows: the central control system in the prior art is used to control the starting electric cylinder 21 to move downward at a regular time, thereby driving the telescopic plate 22 and the convex groove plate 23 to move downward together. The convex groove plate 23 that moves downward will stretch the corrugated tube 25 fixed at one end, so that a negative pressure suction force is generated inside the tube body. Therefore, in the process of the convex groove plate 23 moving downward, the dust attached to the surface of the heat dissipation mesh plate 12 is sucked together through the bent suction tube 26 and the suction bucket 27, so as to achieve the effect of suction while moving downward, and avoid excessive accumulation of dust affecting the heat dissipation mesh plate. 12 has a heat dissipation effect. On the contrary, when the bellows 25 is passively moved upward and contracted, the gas inside will be squeezed to produce squeezed gas, and then the compressed gas will carry the sucked dust through the straight pipe 28 and enter the dust box 230 for unified collection, so that the sealing cover 231 on the dust box 230 can be directly opened later to clean the dust inside uniformly. The one-way valves 29 respectively installed on the bent suction pipe 26 and the straight pipe 28 are used to control the two to only have one-way flow of gas, thereby realizing the working process described above; At the same time, during the passive downward movement of the convex groove plate 23, the two T-shaped sliders 232 installed thereon will perform limited and guided translation in the T-shaped slide grooves 234 correspondingly opened on the vertical plate 233, until the rubber abutment plates 2301 installed on both sides of the top of the convex groove plate 23 are elastically pressed against the guardrail 236. As the convex groove plate 23 continues to move downward, it will repeatedly slide and press against one end of each guardrail 236, so that the pushed guardrail 236 will simultaneously stretch the connected elastic telescopic member 235. When the subsequent baffle 236 does not apply pressure, the elastic telescopic part 235 can drive it to automatically reset, and the pushed baffle 236 also drives the connected multiple through-hole brushes 237 to pass through the heat dissipation mesh 12 at the same time to make through holes for it, so as to prevent dust from covering its surface and reducing the heat dissipation effect. In this way, the heat dissipation mesh 12 used for the heat dissipation effect is cleaned by a double-layer cleaning method of clearing the holes and cleaning the dust at the same time. The whole cleaning process does not require manual operation, thereby improving the efficiency of cleaning and heat dissipation.
