Description

Technical Field

[0004] However, the above mobile intelligent charging pile equipment still has the following defects during use:

[0005] Since charging piles are mobile structures, their safety performance faces significant challenges. When in motion, the internal power structure of the charging pile may be damaged due to vibration, increasing the risk of fire. Once a fire occurs, especially when the mobile charging pile is located in narrow spaces such as elevators and underground garages, these environments not only restrict the entry of fire-fighting equipment, but also make it extremely difficult to effectively cool down and extinguish the fire.

[0021] Beneficial effects of the present invention:

[0022] 1. By setting up a fire extinguishing mechanism, when a fire occurs accidentally in the charging box, the fire extinguishing device can respond quickly and start automatically, directly extinguishing the fire at the fire source, improving efficiency and enhancing safety; when a burning situation is detected, the extrusion mechanism is controlled to start, quickly filling the gap between the shell and the charging box, effectively squeezing out the air therein; in this way, the fire extinguishing material released by the fire extinguisher can cover the charging box faster and more completely, isolating oxygen, and achieving a fast and efficient fire extinguishing effect; this mechanism not only improves the fire extinguishing efficiency, but also enhances the overall safety of the system, ensuring that sudden fires can be responded to in a timely manner even in a small space;

[0023] 2.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0038] like Figures 1 to 10 As shown, mobile intelligent charging pile, reference Figures 1 to 3 and Figure 5 , including a mobile base 1, on which a shell 2 and a charging box 3 are provided, and the charging box 3 is arranged in the shell 2; an auxiliary fire extinguishing mechanism 5 is arranged on the mobile base 1; the auxiliary fire extinguishing mechanism 5 includes: a mounting seat 51, the mounting seat 51 is arranged on the mobile base 1, and the fire extinguisher 4 is arranged on the mounting seat 51; a delivery pipe 52, the input end of the delivery pipe 52 passes through the mounting seat 51 to be connected with the fire extinguisher 4, and the output end of the delivery pipe 52 passes through the shell 2 and is inserted into the gap between the bottom of the charging box 3 and the mobile base 1; and an extrusion mechanism 55, the extrusion mechanism 55 is arranged in the shell 2; when combustion occurs in the shell 2, the extrusion mechanism 55 is used to squeeze and discharge the air in the space between the shell 2 and the charging box 3.

[0039] It should be noted that when the mobile smart charging pile is placed in a small space, the fire extinguishing operation can be performed without manually taking out the fire extinguisher 4. Specifically, the bottom of the fire extinguisher 4 is connected to the bottom of the charging box 3 inside the shell 2 via the delivery pipe 52; this design allows the fire extinguishing device to respond quickly to the fire source and automatically extinguish the fire when an accidental fire occurs in the charging box 3, thereby improving the fire extinguishing efficiency and enhancing the safety of use; such an arrangement not only saves response time in an emergency, but also effectively utilizes limited space, ensuring the safety of the charging pile and its surrounding environment;

[0040] A certain gap is reserved between the inside of the shell 2 and the charging box 3 to ensure that the charging box 3 can effectively dissipate heat during normal use. However, this design may have an adverse effect when the charging box 3 burns: the air in the gap will fuel the flame, thereby hindering the effectiveness of the fire extinguishing work. In order to solve this problem, when a combustion is detected in the charging box 3, the extrusion mechanism 55 will be automatically triggered to start. The function of this mechanism is to quickly fill the gap between the inside of the shell 2 and the charging box 3, and effectively squeeze out the air therein. In this way, when the fire extinguishing matrix is ​​released through the fire extinguisher 4, the fire extinguishing material can quickly and completely wrap and cover the charging box 3, isolating the air, and achieving a quick and efficient fire extinguishing effect. This mechanism not only improves the efficiency of fire extinguishing, but also enhances the overall safety of the system, ensuring that sudden fires can be responded to in a timely manner even in a small space.

[0041] like Figures 1 to 4 As shown, a one-way valve 53 is provided at the bottom of the fire extinguisher 4, and a top block 54 with a through hole is provided at the input end of the delivery pipe 52; when the fire extinguisher 4 is set on the mounting seat 51, the top block 54 abuts against the top ball of the one-way valve 53, so that the one-way valve 53 is forced to open, and the interior of the fire extinguisher 4 is connected with the delivery pipe 52 through the through hole on the top block 54; a solenoid valve is installed on the delivery pipe 52.

[0042] It should be noted that when combustion occurs inside the housing 2, the solenoid valve will be automatically activated to open the delivery pipe 52. At this time, the fire extinguishing matrix in the fire extinguisher 4 passes through the one-way valve 53, enters the delivery pipe 52 from the through hole of the top block 54, and directly sprays the fire extinguishing matrix to the bottom of the charging box 3, achieving rapid and effective fire extinguishing. This process ensures that the fire extinguishing material can quickly reach the fire source location, improving the fire extinguishing efficiency;

[0043] If a fire occurs outside the housing 2 and a fire extinguisher 4 is needed to extinguish the fire, the fire extinguisher 4 can be directly removed from the mounting seat 51. During the removal process, the one-way valve 53 is separated from the top block 54, and the blocking function of the bottom of the fire extinguisher 4 is restored, ensuring that the fire extinguisher 4 can be used normally like a common fire extinguishing device to deal with external fire situations. This design not only ensures a timely response to internal fires, but also provides a flexible way to deal with external fires, enhancing overall safety and practicality.

[0044] like Figures 1 to 3 and Figures 5 and 6 As shown, the extrusion mechanism 55 includes an expansion mechanism 551 and a first linkage mechanism 552; the expansion mechanism 551 is arranged between the shell 2 and the charging box 3, and the first linkage mechanism 552 is arranged between the output end of the delivery pipe 52 and the expansion mechanism 551; when the fire extinguishing matrix is ​​discharged from the output end of the delivery pipe 52, the expansion mechanism 551 can be driven by the first linkage mechanism 552 to move and expand to fill the space between the shell 2 and the charging box 3.

[0045] When combustion occurs inside the shell 2 and triggers the fire extinguishing matrix to be discharged from the delivery pipe 52, the impact force generated by the fire extinguishing matrix when passing through the delivery pipe 52 will activate the first linkage mechanism 552. Subsequently, the movement of the first linkage mechanism 552 will drive the expansion mechanism 551 to start. This chain reaction ensures that while the fire extinguishing matrix is ​​erupting, the expansion mechanism 551 can be automatically started to squeeze out the air in the shell 2. In this way, during the fire extinguishing process, not only can the fire source be quickly and effectively covered, but also the oxygen supply can be reduced by excluding air, further enhancing the fire extinguishing effect and ensuring that the fire is quickly controlled. This design realizes the simultaneous implementation of fire extinguishing and air displacement, significantly improving the efficiency and safety of fire extinguishing.

[0046] like Figures 5 to 8 As shown, the expansion mechanism 551 includes a mounting plate 5511, a rotating plate 5512, a first isolation cloth 5513, a second isolation cloth 5514 and a compression spring 5515; the mounting plate 5511 is fixed to the shell 2, the rotating plate 5512 is hinged to the mounting plate 5511, and the shell 2 and the side wall of the first isolation cloth 5513 are connected through the first isolation cloth 5513; the second isolation cloth 5514 is arranged between the mounting plate 5511 and the rotating plate 5512; a sealed cavity is surrounded by the shell 2, the mounting plate 5511, the rotating plate 5512, the first isolation cloth 5513 and the second isolation cloth 5514; an opening portion connected to the sealed cavity is opened on the shell 2; the compression spring 5515 is arranged between the shell 2 and the rotating plate 5512.

[0047] When the fire extinguishing matrix is ​​discharged from the delivery pipe 52, the impact force generated triggers the first linkage mechanism 552, which in turn drives the expansion mechanism 551 to start. At the same time, the originally restricted compression spring 5515 is released, pushing the rotating plate 5512 to rotate, thereby increasing the space of the sealed cavity. During the rotation of the rotating plate 5512, due to the presence of the first isolation cloth 5513 and the second isolation cloth 5514, it is ensured that the sealed cavity and the inside of the shell 2 always maintain expansion in an isolated state. This not only achieves effective squeezing of the air in the shell 2, but also ensures that the air can be quickly discharged, thereby improving the fire extinguishing efficiency. Through this design, the expansion mechanism 551 is automatically started during the fire extinguishing process, which can not only quickly expand the sealed cavity space, but also effectively isolate and squeeze the air, providing strong support for the fire extinguishing work, and significantly enhancing the overall safety and fire extinguishing effect.

[0048] like Figures 2 to 3 As shown, a heat dissipation channel is provided on the top of the shell 2, and the interior of the shell 2 is connected to the outside through the heat dissipation channel; an air suction pipe 5516 is provided on the shell 2; one end of the air suction pipe 5516 is connected to the sealed cavity through an opening; the other end of the air suction pipe 5516 is provided close to the heat dissipation channel on the top of the shell 2.

[0049] When the expansion mechanism 551 is started, negative pressure is generated inside it, thereby sucking air from the outside through the air suction pipe 5516 to supplement the expansion space. This process causes the port position of the air suction pipe 5516 close to the heat dissipation channel to generate significant suction, which speeds up the flow of air in the heat dissipation channel. Therefore, the air in the shell 2 can be discharged more quickly, further improving the fire extinguishing efficiency. Specifically, the activation of the expansion mechanism 551 not only directly squeezes the air in the shell 2, but also enhances the air discharge rate through the negative pressure effect generated, ensuring that the fire extinguishing matrix can cover the fire source more quickly and evenly, thereby achieving a more efficient fire extinguishing effect. This design cleverly utilizes physical principles, optimizes the fire extinguishing and smoke exhaust process, and improves the overall safety and response speed of the system.

[0050] like Figure 5 , Figures 7 and 8 and Fig.10 As shown, the first linkage mechanism 552 includes a slide 5521, a rotating rod 5522 and a universal joint 5523; the slide 5521 is slidably connected to the mobile base 1 along the direction of the fire extinguishing matrix being discharged from the delivery pipe 52; a plug is provided on the slide 5521, and when the charging box 3 is in normal use, the plug is plugged into the output end of the delivery pipe 52; one end of the rotating rod 5522 is hinged to the slide 5521, and the other end of the rotating rod 5522 is connected to the rotating plate 5512 through a universal joint 5523; when the charging box 3 is in normal use, the length direction of the rotating rod 5522 remains perpendicular to the sliding direction of the slide 5521.

[0051] It should be noted that when combustion occurs in the shell 2 and the fire extinguishing matrix is ​​introduced into the delivery pipe 52, the fire extinguishing matrix impacts the plug on the delivery pipe 52, breaks the plug and pushes the slide 5521 to move, so that the fire extinguishing matrix can be smoothly led out of the delivery pipe 52 to achieve fire extinguishing. At the same time, the driving force of the fire extinguishing matrix causes the slide 5521 to drive the rotating rod 5522 to rotate, destroying the vertical state between the rotating rod 5522 and the slide 5521, and releasing the restriction of the slide 5521 on the rotation of the rotating plate 5512. At this time, the compression spring 5515, which was originally in a compressed state, is released, pushing the rotating plate 5512 to rotate, thereby expanding the sealed cavity. This chain reaction not only ensures that the fire extinguishing matrix can quickly cover the fire source, but also squeezes and discharges the air in the shell 2 through the expansion of the sealed cavity, further improving the efficiency and safety of fire extinguishing. The whole process realizes the simultaneous implementation of fire extinguishing and air exhausting, optimizes the fire response mechanism, and ensures rapid and effective control of the fire.

[0052] like Figures 6 to 10 As shown, a second linkage mechanism 553 is provided between the mounting plate 5511 and the rotating plate 5512; when the first linkage mechanism 552 drives the rotating plate 5512 to rotate, the rotating plate 5512 can be driven to move by the second linkage mechanism 553 to increase the expansion degree of the sealing cavity.

[0053] In order to further increase the expansion degree of the sealed cavity and speed up the air exhaust speed, a second linkage mechanism 553 is provided. When the rotating plate 5512 starts to rotate, it drives the second linkage mechanism 553 to move, so that the sealed cavity can further expand. Through the coordinated use of the expansion mechanism 551 and the second linkage mechanism 553, after the first linkage mechanism 552 has increased the sealed cavity space to a certain extent, the second linkage mechanism 553 is started to realize the gradual and sequential increase of the sealed cavity. This design not only effectively controls the speed of extrusion and prevents the sealed cavity from expanding too quickly and causing excessive positive pressure in the shell 2, but also avoids excessive impact and potential damage to the electronic components in the shell 2. The entire process ensures the efficient implementation of fire extinguishing and air exhaust, while protecting the safety of internal equipment and achieving a rapid and controlled fire extinguishing effect;

[0054] Specifically, the mechanism first triggers the first linkage mechanism 552 by the flow of the fire extinguishing matrix, which promotes the initial expansion of the sealed cavity; then, as the rotating plate 5512 rotates, the second linkage mechanism 553 is activated, allowing the sealed cavity to further expand. This staged expansion design can ensure rapid exhaust of air while maintaining precise control of the expansion rate during the process.

[0055] like Figures 6 to 10 As shown, the second linkage mechanism 553 includes a connecting plate 5531, an inserting shaft 5532 and a clamping mechanism; the inserting shaft 5532 is fixed to the connecting plate 5531; one side of the connecting plate 5531 is slidably connected to the mounting plate 5511 through the inserting shaft 5532, and the other side of the connecting plate 5531 is hinged to the rotating plate 5512; the clamping mechanism is arranged between the mounting plate 5511 and the connecting plate 5531; when the rotating plate 5512 rotates, the clamping mechanism can be driven to open to release the restriction on the connecting plate 5531, so that The connecting plate 5531 can move axially along the insertion shaft 5532; the clamping mechanism includes an elastic sheet 5533 fixed on the mounting plate 5511, a protrusion 5534 is arranged on the elastic sheet 5533, and a limiting groove 5535 adapted to the protrusion 5534 is opened on the connecting plate 5531; a protrusion 5536 is arranged on the rotating plate 5512, and when the rotating plate 5512 drives the protrusion 5536 to rotate, the elastic sheet 5533 can be pushed to deform, so that the protrusion 5534 is separated from the limiting groove 5535.

[0056] When the rotating plate 5512 starts to rotate, it drives the raised portion 5536 thereon to rotate together. As the rotation proceeds, the raised portion 5536 gradually approaches and eventually contacts the elastic sheet 5533. During the continued rotation, the raised portion 5536 pushes the elastic sheet 5533 to deform, causing the protrusion 5534 on the elastic sheet 5533 to separate from the limiting groove 5535. At this time, the compression spring 5515, which was originally in a compressed state, releases its elastic force, pushing the connecting plate 5531 away from the mounting plate 5511, further increasing the space of the sealing cavity. This action not only increases the volume of the sealing cavity, but also effectively squeezes the air in the shell 2, accelerating the discharge of the air, thereby achieving the purpose of quickly emptying the air in the shell 2;

[0057] Specifically, this process triggers a series of mechanical linkages through the rotation of the rotating plate 5512: first, the contact and deformation of the protrusion 5536 and the elastic sheet 5533 release the position restriction on the connecting plate 5531; then, the restoring force of the compression spring 5515 causes the connecting plate 5531 to move, expanding the sealed cavity space. This design ensures that during the fire extinguishing process, the sealed cavity can expand gradually and in a controlled manner, effectively squeezing out the air in the housing 2, improving the fire extinguishing efficiency, and avoiding damage to the internal electronic components that may be caused by excessive expansion.

[0058] like Figures 1 to 3 As shown, a controller is provided on the mobile base 1, and temperature sensors are provided at the bottom of the charging box 3 and at a position in the shell 2 away from the charging box 3; and the two temperature sensors and the solenoid valves are connected to the controller through electrical control; it can be understood that the controller, temperature sensor and solenoid valve are all existing technologies, which are not drawn in the figure and will not be described in detail.

[0059] When the temperature sensor at the bottom of the charging box 3 detects that the temperature is too high, the controller will automatically open the solenoid valve, so that the fire extinguishing matrix in the fire extinguisher 4 is introduced into the bottom of the charging box 3 through the delivery pipe 52 to achieve the purpose of cooling and extinguishing the fire. The fire extinguishing matrix continues to spray until another temperature sensor detects that the temperature drops to a suitable value within the safe range. At this time, it is judged that the fire extinguishing is completed, and the solenoid valve is closed through the controller to stop the release of the fire extinguishing matrix;

[0060] In case of a fire outside the housing 2, the user can directly pull out the fire extinguisher 4 from the mounting base 51 to extinguish the fire outside the housing 2. This design not only ensures that the internal fire can be automatically and timely controlled, but also provides a flexible manual fire extinguishing method for the external fire, thereby improving the overall safety and the ability to cope with emergencies.
