Description

Technical Field

[0001] This invention relates to the field of fire protection technology for charging piles, specifically to a fire early warning system and method for energy storage charging piles. Background Technology

[0002] Electric vehicles are vehicles that use onboard power sources to drive their wheels with electric motors and meet all road traffic and safety regulations. Currently, charging devices mainly charge electric vehicles using AC and DC power, and charging stations or charging piles also primarily use AC and DC power. However, excessive current during charging can easily cause internal combustion within the charging pile, resulting in relatively low safety performance.

[0003] Utility model application CN202121697111.4 (hereinafter referred to as Prior Art 1) discloses a new energy charging pile with an anti-self-ignition interface, including a base, an installation shell fixedly installed on the top of the base, a charging handle connected to the bottom right side of the installation shell, an interface on the top of the charging handle, two conductive rods fixedly installed inside the interface, and an exhaust pipe connected to the left side of the bottom of the charging handle. This utility model uses a base for installing the installation shell and a charging handle for charging the vehicle. The cooperation between the installation cylinder, installation rods, motor, air duct, and exhaust pipe delivers external air to the inside of the interface to cool the conductive rods, thereby preventing the conductive rods from overheating and causing the charging handle to spontaneously combust. It also solves the problem of heat generation at the connection between the charging pile connector and the vehicle due to the large current during use.

[0004] However, the existing technology 1 still has not solved the technical problem of spontaneous combustion of the charging pile itself, and the safety of the charging equipment in the existing technology still needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a fire alarm system and method for energy storage charging piles, which can effectively solve the technical problem of excessive current during charging, leading to spontaneous combustion of charging piles and low safety performance in practical use.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] A fire alarm system for energy storage charging piles includes an outer shell and a charging pile body installed inside the outer shell. The outer shell is provided with a socket, and the charging pile body is connected to a charging gun. A temperature sensor and a smoke sensor are installed inside the outer shell. The temperature sensor and the smoke sensor are connected to a fire control room located at a remote location via a cloud platform.

[0008] The outer casing is also equipped with an automatic power-off mechanism, which includes a mounting plate, a fixed conductive block, a sliding conductive block and a fuse block. The mounting plate is made of insulating material. The fixed conductive block is fixedly installed on the inner wall of the mounting plate. The sliding conductive block is slidably installed on the mounting plate. The fixed conductive block and the sliding conductive block are arranged parallel to each other and there is a gap between them.

[0009] Both the fixed conductive block and the sliding conductive block have mounting grooves on opposite sides. The shape of the fuse block matches the mounting grooves, and the fixed conductive block and the sliding conductive block are locked and fixed together by the fuse block.

[0010] The fixed conductive block is connected to the charging pile body via a first cable, and the sliding conductive block is connected to the wires in the charging gun via a second cable. Weights are connected to the upper and lower ends of the sliding conductive block.

[0011] The second cable is a spiral cable.

[0012] Further optimization resulted in a prismatic cross-section for the fuse block.

[0013] The mounting plate is equipped with guide rails, and the sliding conductive block is equipped with guide grooves. The sliding conductive block is slidably mounted on the mounting plate via the guide rails and guide grooves.

[0014] Further optimization involves installing a limit plate on the mounting plate, a pressure ring on the guide rail, and a spring on the guide rail. The upper end of the spring is connected to the pressure ring, and the lower end is connected to the limit plate.

[0015] The limiting plate is equipped with a limiting post.

[0016] Furthermore, a buffer pad is provided on the limiting post.

[0017] The outer casing has an air inlet and an air outlet, and a circulating fan is installed inside the casing.

[0018] The present invention also discloses a fire early warning method for energy storage charging piles, including the above-mentioned fire early warning system for energy storage charging piles.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In practical use, this invention achieves real-time monitoring through the installation of temperature and smoke sensors. The temperature sensor monitors the temperature in real time, and in the event of a fire, these sensors provide immediate feedback, transmitting the monitored signals to a remote fire control room for early warning. Simultaneously, an automatic power-off device automatically cuts off the circuit in the event of a large current. This is achieved through a combination of fixed and sliding conductive blocks and a fuse. Because the sliding conductive block is supported by a weight, when a large current occurs in the circuit, the fuse will melt under the influence of the current. The weight also ensures that the fixed and sliding conductive blocks disconnect instantly, effectively shortening the melting time and reducing the probability of spontaneous combustion.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] Example 1

[0035] See Figures 1-3 This embodiment discloses a fire alarm system for energy storage charging piles, including a housing 101 and a charging pile body 102 disposed inside the housing 101. The housing 101 is provided with a socket 103, and the charging pile body 102 is connected to a charging gun 104. A temperature sensor and a smoke sensor are disposed inside the housing 101. The temperature sensor and the smoke sensor are connected to a fire control room located at a remote location via a cloud platform.

[0036] An automatic power-off mechanism 105 is also provided inside the housing 101. The automatic power-off mechanism 105 includes a mounting plate 106, a fixed conductive block 107, a sliding conductive block 108, and a fuse block 109. The mounting plate 106 is made of insulating material. The fixed conductive block 107 is fixedly installed on the inner wall of the mounting plate 106. The sliding conductive block 108 is slidably installed on the mounting plate 106. The fixed conductive block 107 and the sliding conductive block 108 are arranged parallel to each other and there is a gap between them.

[0037] Both the fixed conductive block 107 and the sliding conductive block 108 are provided with mounting grooves 110 on opposite sides. The shape of the fuse block 109 matches the mounting groove 110. The fixed conductive block 107 and the sliding conductive block 108 are locked and fixed together by the fuse block 109.

[0038] The fixed conductive block 107 is connected to the charging pile body 102 via the first cable 111, and the sliding conductive block 108 is connected to the wire in the charging gun 104 via the second cable 112. The upper and lower ends of the sliding conductive block 108 are connected to weights 113.

[0039] In practical use, this invention achieves real-time monitoring through the installation of temperature and smoke sensors. The temperature sensor monitors the temperature in real time, and in the event of a fire, the temperature and smoke sensors can provide feedback immediately, sending the monitored signals to the remote fire control room in real time to achieve remote early warning.

[0040] Meanwhile, in actual use, the automatic power-off device can automatically cut off the circuit when a large current occurs. The circuit is made conductive by the fixed conductive block 107, the sliding conductive block 108 and the fuse. Since the sliding conductive block 108 is equipped with a weight 113, when a large current occurs in the circuit, the fuse will be melted by the current. At this time, under the action of the weight 113, the fixed conductive block 107 and the sliding conductive block 108 can be disconnected in an instant, which can effectively shorten the melting time and reduce the probability of spontaneous combustion.

[0041] The second cable 112 is a spiral cable, which makes it easier for the second cable 112 to move along with the sliding conductive block 108 when it moves.

[0042] The fuse block 109 has a prismatic cross-section, which enables the fuse block 109 to position the fixed conductive block 107 and the sliding conductive block 108 when it is engaged with the mounting groove 110.

[0043] The mounting plate 106 is provided with a guide rail 114, and the sliding conductive block 108 is provided with a guide groove. The sliding conductive block 108 is slidably mounted on the mounting plate 106 through the guide rail 114 and the guide groove. The guide rail 114 and the guide groove make the sliding conductive block more stable when sliding.

[0044] The mounting plate 106 is provided with a limit plate 115, the guide rail 114 is fitted with a pressure ring 116, and the guide rail 114 is fitted with a spring 117. The upper end of the spring 117 is connected to the pressure ring 116, and the lower end is connected to the limit plate 115. The pressure ring 116 and the spring 117 can form a buffer structure to prevent the sliding guide rail 114 from sliding down under the action of the weight 113 and causing a strong impact.

[0045] The limiting plate 115 is provided with a limiting post 118, which can limit the pressure ring 116.

[0046] Among them, the limiting post 118 is provided with a buffer pad 119, which can serve as a buffer.

[0047] The outer casing 101 is provided with an air inlet and an air outlet, and a circulating fan is provided inside the outer casing 101.

[0048] The heat dissipation effect can be improved by setting up air inlets, air outlets and circulating fans.

[0049] Example 2

[0050] This embodiment is a further optimization based on Embodiment 1. In this embodiment, a stepped surface 120 is provided on the outer shell 101, and a groove 121 and a through hole 122 communicating with the groove 121 are provided on the stepped surface 120. A sealing ring 123 is slidably provided on the outer shell 101, and a sealing part corresponding to the groove 121 is provided on the sealing ring 123. The sealing part is supported by a heat-resistant material. A first guide wheel 124 is provided inside the outer shell 101, and a pull rope 125 is provided on the sealing ring 123. The pull rope 125 passes through the through hole 122 and is wound around the first guide wheel 124 and then connected to the sliding conductive block 108.

[0051] The air inlet and air outlet are formed by a series of through holes arranged in rows 122.

[0052] When an overload causes the fuse block 109 to melt, the sliding conductive block 108 slides down under the action of the weight 113, causing the fixed conductive block 107 to disengage from the sliding conductive block 108, thus achieving the purpose of quickly disconnecting the circuit. At the same time, under the action of the pull rope 125, as the sliding conductive block 108 slides down, the sealing ring 123 moves upward, and the sealing part on the sealing ring 123 seals the groove 121, thus sealing the through hole 122 and forming a sealed structure inside the outer shell 101. In this way, even if a short circuit occurs inside and spontaneous combustion occurs, a sealed structure can be formed inside the outer shell 101 immediately to isolate oxygen and achieve the purpose of rapid fire extinguishing, which can effectively improve the safety during use.

[0053] Example 3

[0054] This embodiment is a further optimization based on Embodiment 2. In this embodiment, a push ring 126 is slidably disposed on the outer shell 101. The push ring 126 is located below the sealing ring 123. The sealing ring 123 is provided with a first through hole 127. The pull rope 125 passes through the first through hole 127 and is connected to the push ring 126. The push ring 126 is provided with a mounting hole, and a support spring 128 is provided in the mounting hole. In this way, after the pull rope 125 pulls the push ring 126 to move, under the action of the support spring 128, a buffer anti-collision mechanism can be formed between the sealing ring 123 and the push ring 126. When the pull rope 125 pulls the push ring 126 upward, the sealing ring 123 is prevented from colliding with the stepped surface 120 of the outer shell 101. Under the action of the support spring 128, the hard contact is changed to a soft contact, thereby improving the shock absorption effect.

[0055] Example 4

[0056] This embodiment discloses a fire early warning method for energy storage charging piles, including the use of the fire early warning system for energy storage charging piles described in Embodiment 1;

[0057] The specific early warning methods are as follows:

[0058] Real-time monitoring is achieved by using temperature and smoke sensors, and the temperature is monitored in real time by using temperature sensors.

[0059] When a fire occurs, temperature and smoke sensors can provide immediate feedback, sending the monitored signals to a remote fire control room in real time to achieve remote early warning.

[0060] Meanwhile, the automatic power-off device can automatically cut off the circuit when a large current occurs. The circuit is made conductive by the fixed conductive block 107, the sliding conductive block 108 and the fuse. Since the sliding conductive block 108 is equipped with a weight 113, when a large current occurs in the circuit, the fuse will be melted by the current. At this time, under the action of the weight 113, the fixed conductive block 107 and the sliding conductive block 108 can be disconnected in an instant, which can effectively shorten the melting time and reduce the probability of spontaneous combustion.
