[0026] The plug-in low-voltage power generation equipment and power generation vehicle of the present invention have the following beneficial effects:

[0027] The plug-in low-voltage power generation equipment and power generation vehicle of the present invention consider installing a female plug at the power distribution point, and converting the low-voltage cable into a male plug at the power generation vehicle end. When maintaining power, the male plug can be directly inserted into the female plug, which is simple and convenient to use.

[0028] Based on the provision of a first backup power supply and a second backup power supply, when using the power in the first backup power supply, not only can the current and voltage be supplied stably and continuously, but the fan assembly can also be started at the same time to charge the second backup power supply. The first backup power supply and the second backup power supply are used alternately to achieve the purpose of continuous power supply.

[0029] When the conductor sheath is subjected to tension, the conductor sheath can drive the insulating elastic sleeve to slide on the outside of the metal conductive sleeve to achieve buffering and avoidance, preventing the conductor sheath from breaking due to excessive tension. When the insulating elastic sleeve slides on the outside of the metal conductive sleeve, the copper core and the first limiting ring move synchronously in the metal conductive sleeve, and the metal conductive sleeve is in contact with the copper core, ensuring that the metal conductive sleeve and the copper core maintain a real-time electrical connection.

[0030] The present invention can not only automatically extend and retract to reduce the influence of tension on the outer skin of the conductor, but also dissipate heat at the connection position between the copper core and the conductive column during automatic extension and retraction, thereby reducing the influence of heat on the current transmission efficiency.

[0031] The partition curtain divides the interior of the carriage into two spaces, so that the diesel generator set that is prone to generate heat is isolated in a chamber alone, avoiding the problem of the heat generated by the diesel generator set causing the high operating temperature of the first bellows.

[0032] The partition curtain can not only isolate the battery pack and the diesel generator set, but also connect the two spaces, making it convenient for personnel to inspect the diesel generator set or connect the two spaces when necessary.

[0033] A sponge block is installed in the drain outlet. Due to the obstruction of the sponge block, the air flow rate is reduced. Therefore, when the hot air enters the heat dissipation chamber, it will be discharged through the unobstructed heat dissipation outlet first, thus avoiding the phenomenon that the hot air discharged from the drain outlet is easily sucked into the heat dissipation inlet.

[0034] If the motor in the second bellows is started, the air will blow in the opposite direction, and the dust and other impurities around the battery pack can be discharged into the first bellows through the air holes on the first bellows for collection, thereby achieving the purpose of dust removal and preventing dust from affecting the heat dissipation of the battery pack. In actual use, the two motors are switched regularly. When the wind blows upward from the bottom of the battery pack, the dust on the surface of the battery pack will be lifted up, making it difficult for the dust to stubbornly adhere to the surface of the battery pack. When the wind blows downward from the top of the battery pack, all the dust around the battery pack will be collected in the first bellows, and the dust collection efficiency is high.

[0035] With reference to the following description and drawings, a specific embodiment of the present invention is disclosed in detail, indicating the manner in which the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereby, and within the spirit and scope of the appended claims, the embodiments of the present invention include many changes, modifications and equivalents.

[0051] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0052] It should be noted that when an element is referred to as being "disposed on, provided with" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs. The terms used in the specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0054] Please refer to the instruction manual Figure 1-14 The present invention provides a technical solution: a plug-in low-voltage power generation device, including: a fan assembly 33, an AC / DC converter, a battery pack 21, a male plug and a female plug.

[0055] In order to solve the problem that when a low-voltage generator is used to maintain power during a planned power outage or a fault power outage, the present invention needs to disassemble and assemble screws, reconnect wires, and then power on at the distribution station side, and the process is cumbersome and the operation is troublesome. The male plug provided includes a wire sheath 2 and a plug 3, and the end of the wire sheath 2 away from the plug 3 is connected to the battery pack 21. The female plug is installed at the connection end of the distribution station, and the female plug is matched and plugged with the plug 3. When maintaining power, the male plug can be directly inserted into the female plug. The use is simple and convenient, replacing the prior art that needs to disassemble and assemble screws, reconnect wires, and then power on at the distribution station side, and the process is cumbersome and the operation is troublesome.

[0056] The fan assembly 33 generates electricity by diesel drive; the AC / DC converter is used to convert the alternating current generated by the fan assembly 33 into direct current; the battery pack 21 includes a first backup power supply and a second backup power supply, a first switch module is provided between the output end of the AC / DC converter and the input end of the first backup power supply, and a second switch module is provided between the output end of the AC / DC converter and the input end of the second backup power supply. When the first switch module is turned on, the first backup power supply is in a charging state, and when the second switch module is turned on, the second backup power supply is in a charging state. Based on the provision of the first backup power supply and the second backup power supply, it is convenient to continuously realize stable power supply. In the prior art, if the fan assembly 33 is used to directly generate electricity, since the fan assembly 33 has a critical point of power generation when starting, the current and voltage are unstable. If the fan assembly 33 is directly used for power supply, the life of the electrical equipment will be reduced due to the instability of the current and voltage. Therefore, in the present invention, the electricity generated by the fan assembly 33 is first stored in the first backup power supply and the second backup power supply. For example, when the power in the first backup power supply is used, the current and voltage can not only be stably and continuously supplied, but also the fan assembly 33 can be started at the same time to charge the second backup power supply. The first backup power supply and the second backup power supply are used alternately to achieve the purpose of continuous power supply.

[0057] The first backup power supply and the second backup power supply are also provided with a third switch module and a fourth switch module respectively. When the third switch module is turned on, the first backup power supply is connected to the distribution connection terminal. When the fourth switch module is turned on, the second backup power supply is connected to the distribution connection terminal, thereby achieving the purpose of switching to use the first backup power supply or the second backup power supply.

[0058] It should be noted that both the first backup power supply and the second backup power supply can use lithium batteries, and the first switch module, the second switch module, the third switch module and the fourth switch module can use switches for controlling the on and off of the circuit, which is a common existing technology and will not be elaborated here.

[0059] Considering that there is a risk of disconnection or loosening of the connection when using a plug-in power supply, the present invention provides a socket 5 on the plug 3, a copper core 10 is provided inside the wire sheath 2, one end of the copper core 10 is connected to a conductive connecting ring 6, and the other end of the copper core 10 is integrally provided with a first limiting ring 17, and a telescopic component 7 is provided at the end of the wire sheath 2 away from the conductive connecting ring 6, and the telescopic component 7 includes an insulating fixing sleeve 8 and an insulating elastic sleeve 9, the insulating elastic sleeve 9 is integrally connected to the wire sheath 2, and the end of the insulating elastic sleeve 9 away from the wire sheath 2 is flexible between the insulating fixing sleeve 8 and the insulating elastic sleeve 9. The conductive column 12 is fixedly arranged at the inner circle of the insulating fixed sleeve 8, and the metal conductive sleeve 13 is fixedly arranged at the outer circle of the end of the conductive column 12. The metal conductive sleeve 13 is movably sleeved at the outer circle of the first limiting ring 17, and the metal conductive sleeve 13 is located between the insulating elastic sleeve 9 and the copper core 10. The diameter of the insulating elastic sleeve 9 is greater than the diameter of the copper core 10. The end of the insulating elastic sleeve 9 away from the wire sheath 2 is fixedly provided with a second limiting ring 19, and the second limiting ring 19 is movably fitted at the outer circle of the metal conductive sleeve 13. The telescopic component 7 extends into the interior of the socket 5, and one end of the socket 5 The end is open and connected to the female plug. A rubber ring 11 is fixedly arranged at the inner ring of the other end of the jack 5. The rubber ring 11 is movably fitted on the outer ring of the wire sheath 2. The rubber ring 11 and the second limiting ring 19 are respectively fixedly arranged on the sides close to each other with a first magnet 14 and a second magnet 18. The end of the insulating elastic sleeve 9 away from the insulating fixed sleeve 8 is provided with a second air hole 16, and the end of the metal conductive sleeve 13 away from the conductive column 12 is provided with a first air hole 15. The outer ring of the insulating fixed sleeve 8 is fixed on the inner wall of the jack 5. When working, the female plug is inserted into the jack 5 and docked with the conductive column 12, and the current The wire flows through the conductive column 12, the metal conductive sleeve 13 and the copper core 10 in sequence. When the wire sheath 2 is subjected to tension, the wire sheath 2 can drive the insulating elastic sleeve 9 to slide outside the metal conductive sleeve 13 to achieve buffering and avoidance, thereby preventing the wire sheath 2 from breaking due to excessive tension. When the insulating elastic sleeve 9 slides outside the metal conductive sleeve 13, the copper core 10 and the first limiting ring 17 move synchronously in the metal conductive sleeve 13, and the metal conductive sleeve 13 is in contact with the copper core 10, thereby ensuring that the metal conductive sleeve 13 and the copper core 10 maintain a real-time electrical connection.

[0060] Furthermore, due to the setting of the second limiting ring 19 and the first limiting ring 17, it is ensured that the end of the wire sheath 2 will not fall off directly from the jack 5. When the second limiting ring 19 and the rubber ring 11 are close to each other, the second limiting ring 19 will automatically reset due to the repulsive force generated between the first magnet 14 and the second magnet 18, ensuring that when the wire sheath 2 is affected by tension, the wire sheath 2 can automatically expand and contract to adapt.

[0061] Furthermore, since the metal conductive sleeve 13 and the insulating elastic sleeve 9 are respectively provided with the first air hole 15 and the second air hole 16, when the telescopic component 7 at the end of the wire sheath 2 moves, the insulating elastic sleeve 9 will be compressed and deformed due to the pressure of the inner wall of the rubber ring 11, and the first limiting ring 17 moves toward the end of the metal conductive sleeve 13 away from the insulating fixed sleeve 8 to compress the gas inside the metal conductive sleeve 13, so that the high-temperature gas is discharged from the first air hole 15 and the second air hole 16, thereby achieving the purpose of heat dissipation. That is, the present invention can not only automatically expand and contract to reduce the influence of tension on the wire sheath 2, but also dissipate heat at the connection position of the copper core 10 and the conductive column 12 during automatic expansion and contraction, thereby reducing the influence of heat on the current transmission efficiency.

[0062] It should also be noted that the conductive connecting ring 6 on the wire sheath 2 is pre-connected to the connection terminal at the power distribution point or the battery pack 21 for easy connection and use.

[0063] The present invention also discloses a power generation vehicle, comprising: a frame 1 and a carriage 4; wherein the frame 1 is provided with wheels at the bottom, so as to facilitate movement to a designated power distribution connection end for use; the carriage 4 is installed above the frame 1, the fan assembly 33 and the battery pack 21 are both installed in the carriage 4, and the male plug connected to the battery pack 21 is extended to the outer surface of the carriage 4; a liftable curtain 24 is provided in the carriage 4, the curtain 24 is isolated between the battery pack 21 and the fan assembly 33, the curtain 24 is flexible, and the curtain 24 divides the interior of the carriage 4 into two spaces, so that the diesel generator set 20 that is easy to generate heat is isolated in a chamber alone, so as to avoid the problem that the heat generated by the diesel generator set 20 causes the high operating temperature of the first bellows 22, and the curtain 24 is made of thermal insulation cotton and rubber composite, and has good thermal insulation ability.

[0064] The partition curtain 24 can not only isolate the battery pack 21 and the diesel generator set 20, but also connect the two spaces, so that personnel can easily inspect and repair the diesel generator set 20 or connect the two spaces when necessary. The specific implementation scheme is as follows:

[0065] The upper end of the partition curtain 24 is fixed to the top of the carriage 4, and a third magnet 49 is fixedly provided at the bottom of the partition curtain 24. A handle 48 is provided on the third magnet 49. A slide groove 25 is provided on the side inner wall of the carriage 4. The slide groove 25 is arranged along the height direction of the carriage 4. The side of the third magnet 49 is slidably connected in the slide groove 25. A fourth magnet 50 is fixedly provided on the upper surface of the frame 1, and the fourth magnet 50 and the third magnet 49 are in contact with each other; when the third magnet 49 and the fourth magnet 50 are attracted and fixed to each other, the partition curtain 24 is positioned. At this time, the partition curtain 24 isolates the diesel generator set 20 and the battery pack 21. When the third magnet 49 is pulled up by the handle 48, the third magnet 49 slides along the slide groove 25, so that the partition curtain 24 rolls up, thereby connecting the space between the diesel generator set 20 and the battery pack 21.

[0066] As another embodiment, the fourth magnet 50 can also use an electromagnet, and a temperature sensor is attached to the side of the battery pack 21. When the temperature sensor detects that the temperature of the battery pack 21 is too low, in order to maintain the temperature difference of the battery pack 21 in the use environment not too large and maintain a suitable temperature, a controller can be provided to be connected between the temperature sensor and the fourth magnet 50. When the temperature sensor detects that the temperature of the battery pack 21 is too low and feeds this data information back to the controller, the controller controls the current direction passed into the fourth magnet 50 to be opposite. At this time, a repulsive force is generated between the fourth magnet 50 and the third magnet 49, and the third magnet 49 will rise due to the repulsive force, thereby connecting the space between the battery pack 21 and the diesel generator set 20. The heat generated by the diesel generator set 20 during operation will enter the space where the battery pack 21 is located, compensating for the defect of too low temperature around the battery pack 21, facilitating use according to actual needs, and increasing the service life of the battery pack 21.

[0067] Considering that the diesel generator set 20 is installed inside the carriage 4, and the existing diesel generator set 20 usually has a fan assembly 33 for heat dissipation, if the carriage 4 is in a sealed state, it will affect the heat dissipation of the diesel generator set 20. In order to reduce the phenomenon of subsequent modification of the diesel generator set 20 to adapt to the heat dissipation requirements of the diesel generator set 20, a heat dissipation inlet 31 corresponding to the fan assembly 33 on the diesel generator set 20 is provided on one side of the carriage 4, and a filter screen 32 is installed in the heat dissipation inlet 31. A baffle 28 is provided above the diesel generator set 20, and the baffle 28 separates the upper end of the carriage 4 into a heat dissipation chamber 27. The heat dissipation chamber 27 is provided in the heat dissipation chamber 27. 7 is provided with a heat dissipation outlet 26 penetrating the upper surface of the carriage 4 at the upper end, and a heat dissipation column 40 is provided on the baffle 28, and the upper and lower ends of the heat dissipation column 40 are respectively connected to the upper and lower parts of the baffle 28; when working, the diesel generator set 20 uses its own fan assembly 33 to dissipate heat, and the external wind enters the space where the diesel generator set 20 is located after being filtered by the filter net 32, and the wind blows away the heat around the diesel generator set 20, and the hot air passes through the heat dissipation column 40, the heat dissipation chamber 27 and the heat dissipation outlet 26 in sequence and is discharged. The hot air discharge position is set above the carriage 4, away from the heat dissipation inlet 31, to ensure that the discharged hot air will not be sucked into the carriage 4 again.

[0068] When the power truck is used outdoors, it is inevitable that it will rain. In order to prevent rainwater from entering from the heat dissipation outlet 26 and affecting the equipment inside the car 4, the baffle 28 in the present invention is arranged at an angle, and the end of the baffle 28 away from the partition curtain 24 is inclined downward, and the side of the car 4 is provided with a drain port 29 connected to the surface of the baffle 28, and the upper end of the heat dissipation column 40 is fixedly connected to a rain shield 41 through a support. When rainwater enters from the heat dissipation outlet 26, due to the obstruction of the rain shield 41, the rainwater will not enter the heat dissipation column 40, and the rainwater flows along the baffle 28 to the drain port 29 and is discharged to the side, and will not enter the vicinity of the diesel generator set 20.

[0069] A sponge block 30 is installed in the drain port 29. Due to the obstruction of the sponge block 30, the air flow rate is reduced. Therefore, when the hot air enters the heat dissipation chamber 27, it will be discharged through the unobstructed heat dissipation outlet 26 first, thus avoiding the phenomenon that the hot air discharged from the drain port 29 is easily sucked into the heat dissipation inlet 31.
