Description

Technical Field

[0001] The invention belongs to the field of fire protection, and in particular relates to a method and a device for isolating and extinguishing fire in an automobile. Background Art

[0002] With the rapid development of new energy electric vehicles, fire accidents caused by electric vehicles igniting spontaneously or being ignited by external factors have occurred frequently, causing great economic losses and personal injuries to the people. To address the problem of automobile combustion, we need to address it from both internal and external aspects. From the internal aspect, we need to improve battery and automobile fire prevention technology to reduce the probability of automobile combustion; from the external aspect, we need to configure corresponding fire-fighting facilities to quickly extinguish the flames and avoid external losses and personal injuries caused by automobile combustion.

[0003] In the prior art, conventional fire-fighting facilities (such as fire extinguishers or fire hydrants) are usually used to extinguish fires in automobiles. However, since fires in new energy vehicles often originate from short circuits in the electrical system, conventional fire-fighting facilities usually take a long time to extinguish the fire (or even in many cases can only let it burn out on its own). During this process, the burning car is very likely to explode and splash debris outward, and ignite nearby adjacent equipment and facilities, posing a high safety risk. Summary of the invention

[0004] The present invention provides a method for isolating and extinguishing a car fire, and its purpose is to solve the problem that conventional means have relatively large safety risks when extinguishing a car fire.

[0005] In order to achieve the above object, the present invention provides a method for isolating and extinguishing a vehicle fire, comprising the following steps:

[0006] S1, install a fire hood above the parking space;

[0007] S2, release the fire bag cover downwards;

[0008] S3, enveloping the burning car in a fire bladder;

[0009] S4, release fire-fighting substances into the fire-fighting bag cover.

[0010] This solution uses a fire bladder to cover the burning car, reducing the contact between the outside air and the burning car, achieving a preliminary fire extinguishing effect. Afterwards, fire-fighting substances are released into the fire bladder, and the fire-fighting substances come into contact with the burning car, and then the fire of the car is extinguished.

[0011] Preferably, in order to prevent the fire bladder cover from interfering with the parking of the car, in S1 of this solution, the fire bladder cover is in an unexpanded state; in S2, the fire bladder cover is inflated to expand the fire bladder cover.

[0012] When the car is not on fire, the fire bladder cover of the present invention is in an unexpanded state, and the fire bladder cover will not interfere with the parking of the car. When the car is on fire, the fire bladder cover is inflated again, so that the fire bladder cover is expanded. The expanded fire bladder cover covers the burning car.

[0013] Through the above design, compared with directly setting the fire bag cover to an inflated state, the fire bag cover interferes less with the parking space, is convenient for monitoring normal parking and driving, and is more practical.

[0014] Preferably, in order to inject fire-fighting substances into the fire-fighting bag cover, in S2 of this scheme, fire-fighting gas is filled into the fire-fighting bag cover; in S4, when the fire-fighting bag cover is filled with fire-fighting gas reaching a threshold, the fire-fighting bag cover releases the fire-fighting gas into the fire-fighting bag cover.

[0015] This solution fills the fire bladder with firefighting gas, and then when the firefighting gas reaches a threshold, the firefighting gas is released into the fire bladder. In this way, the fire bladder seals the burning car while allowing the firefighting material to contact the burning car, achieving a better fire extinguishing effect on the car. At the same time, since the oxygen concentration inside the fire bladder is reduced, a positive pressure is formed, which prevents new air from entering, achieving a better fire extinguishing effect on the car.

[0016] Preferably, in order to improve the efficiency of fire extinguishing, in S2 described in this solution, when a car fire is detected, the fire bladder cover is automatically inflated.

[0017] When the solution detects that the car is on fire, it automatically inflates the fire bag cover so that the fire bag cover can expand and cover the burning car. Through the above process, the burning car can be quickly isolated from the outside air, and the oxygen concentration between the air bag cover and the car is reduced, and a positive pressure is formed to block new air from entering, so that the fire extinguishing efficiency is higher and the effect is better.

[0018] Preferably, in order to detect whether the car is on fire, the present solution detects the car on fire through temperature, smoke and / or light sensitivity.

[0019] Preferably, in order to facilitate rapid inflation of the fire bag cover, the fire bag cover described in this solution includes an inflation frame and a fireproof wall, the fireproof wall is installed on the inflation frame, and the inflation frame is used to support the fireproof wall.

[0020] The inflatable frame of the present invention can be inflated and expanded. When the inflatable frame is inflated, the inflatable frame supports the fire wall, and the inflatable frame and the fire wall cooperate to form a firefighting bag cover. Since the present invention only needs to inflate the inflatable frame, the firefighting bag cover can be rapidly inflated, and the efficiency is higher.

[0021] In order to solve the problem that conventional means are inefficient in extinguishing automobile fires, the second aspect of the present invention provides an automobile isolation fire prevention device for the above-mentioned automobile isolation fire extinguishing method, comprising:

[0022] A fire bladder cover, wherein the fire bladder cover is provided with a releaser, the fire bladder cover is used to cover a car in a burning state, and the releaser releases a fire extinguishing substance to the car in a burning state;

[0023] An inflation module is connected to the fire bag cover and is used to inject gas into the fire bag cover.

[0024] In this solution, the fire bladder is inflated by the inflation module to expand the fire bladder. The inflated fire bladder can cover the burning car, preventing the outside air from contacting the burning car, and achieving a better car fire extinguishing effect. At the same time, the fire extinguishing material is released to the burning car through the releaser to achieve the fire extinguishing of the car.

[0025] Preferably, in order to facilitate the timely release of the fire bag cover when the car catches fire, the present solution further includes a mounting module, which is arranged above the parking space and is used to accommodate and release the fire bag cover.

[0026] In this solution, the installation module is arranged above the parking space. When a car catches fire, the installation module can release the fire bag cover to the burning car in time. At the same time, the fire bag cover is arranged above the parking space through the installation module, so the fire bag cover will not affect the normal parking of the car, and the practicality is stronger.

[0027] In order to achieve rapid expansion of the fire bag cover, the present solution further includes a fire monitor, which is used to monitor the state of the car.

[0028] This solution will detect the state of the car through the fire monitor. When the car is on fire, the control module controls the inflation module to work, and the inflation module inflates the fire bag cover. Compared with manually operating the fire bag cover to inflate, the above method is more efficient.

[0029] Preferably, in order to release the fire-fighting gas into the interior of the fire-fighting bag cover, the present solution further comprises a pressure monitor, wherein the pressure monitor is installed on the fire-fighting bag cover, and the pressure monitor is used to detect the internal pressure of the fire-fighting bag cover.

[0030] This solution uses a pressure monitor to detect the internal pressure of the fire bladder. When the internal pressure reaches the threshold, the releaser can be controlled to release the firefighting gas. Through the cooperation of the pressure monitor and the releaser, the fire of the car inside the fire bladder can be extinguished. At the same time, the burning car can always remain in the state of being enclosed by the fire bladder.

[0031] The beneficial effects of the present invention are as follows: First, the present solution covers the burning car with the fire bag cover, reduces the contact between the outside air and the burning car, and achieves a preliminary fire extinguishing effect. Then, the fire-fighting material is released into the fire bag cover, and the fire-fighting material contacts the burning car, further promoting the fire extinguishing of the car. Compared with the traditional fire extinguishing method, it is more efficient.

[0032] Second, the present invention covers the burning car with a fire bladder cover, which can play a blocking role, preventing splashing impurities from causing personal injury and damage to external facilities, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0044] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance.

[0045] Example 1

[0046] Basically as attached Figure 1 As shown, a method for isolating and extinguishing a car fire comprises the following steps:

[0047] S1, a fire extinguisher cover 1 is arranged above the parking space of the car. In order to reduce the volume of the fire extinguisher cover 1, the fire extinguisher cover 1 is not inflated and is in a folded state. The folded fire extinguisher cover 1 is conducive to rapid deployment, further improving the fire extinguishing efficiency.

[0048] It can be understood that: in this embodiment, the fire bag cover 1 is arranged above the parking space, so when the car is not on fire, the fire bag cover 1 will not affect the normal entry and exit and parking of the vehicle, and will not affect other adjacent parking spaces. It is more practical and meets the needs of the use of various private parking spaces in practice.

[0049] S2, when a car is on fire, the fire bag cover 1 is inflated, and the fire bag cover 1 is quickly unfolded into a rectangular cover. At the same time, the fire bag cover 1 is released downward, and the burning car can enter the fire bag cover 1 through the bottom opening of the fire bag cover 1.

[0050] It can be understood that: in this embodiment, the fire bag cover 1 is allowed to fall freely downward so that the car can enter the fire bag cover 1. There is no need to configure external force to push the fire bag cover 1 to cover the burning car. The fire bag cover 1 falls freely by gravity, which is more practical.

[0051] It should be noted that the gas filled into the fire bag cover 1 in this embodiment is firefighting gas, and the types of firefighting gas filled include but are not limited to carbon dioxide, IG541, heptafluoropropane, perfluorohexanone, nitrogen, argon and helium. By filling the firefighting gas, when the firefighting bag cover 1 is accidentally damaged, the firefighting gas inside the firefighting bag cover 1 can be quickly and directly released to the vicinity of the car to extinguish the fire of the car.

[0052] In this embodiment, the firefighting bag cover 1 can be inflated manually or automatically by a configured monitoring system. The two inflation modes can be configured at the same time, or only the manual mode can be set. When manual inflation and monitoring inflation by a monitoring system are configured at the same time, manual inflation takes priority.

[0053] When the manual inflation method is used, the staff observes whether the car is burning. If the car is burning, the staff can manually operate it, such as manually opening the valve 32 at the mouth of the gas cylinder to inflate the fire bag cover 1. The fire bag cover 1 is inflated to form a cover body to cover the burning car.

[0054] When the monitoring system is used for automatic inflation, the monitoring system includes a detector, an electric valve 32 and a control module 6. The detector is arranged outside, and can be specifically arranged in a parking space. The detector detects one or more signals of temperature, smoke and fire light, and transmits the detected signal to the control module 6. When the control module 6 receives one or more of the above signals at the same time, it will determine that the car is on fire. The control module 6 sends a start command signal to control the electric valve 32 to open, and the gas cylinder can inflate the inside of the fire bag cover 1.

[0055] S3, when the fire bag cover 1 is unfolded and released downward, the fire bag cover 1 covers the car inside the fire bag cover 1. When the fire bag cover 1 covers the burning car inside, the fire bag cover 1 can reduce the gas flow, so that the burning car is sealed, and the air cannot contact the car in large quantities, which has a preliminary fire extinguishing effect.

[0056] S4, releasing firefighting gas to the car inside the firefighting bag, and further extinguishing the fire of the car by the firefighting gas.

[0057] It should be noted that: an automatic release system is configured in this embodiment, and the firefighting gas is released to the car inside the firefighting bag through the automatic release system. The automatic release system includes a nozzle, a pressure monitor 42 and a control module 6. The nozzle is arranged on the inner wall of the firefighting bag cover 1, and the nozzle is in a connected state with the firefighting bag cover 1. That is, the firefighting gas inside the firefighting bag cover 1 can be released to the car through the nozzle, thereby extinguishing the fire of the car. The pressure monitor 42 is arranged on the firefighting bag cover 1, and the pressure monitor 42 is used to detect the internal pressure of the firefighting bag cover 1. Both the pressure monitor 42 and the nozzle are in a signal connection state with the control module 6. When the pressure monitor 42 detects that the internal air pressure of the firefighting bag cover 1 reaches a certain threshold (at this time the firefighting bag cover 1 is in a stable support state), the control module 6 can control the nozzle to open, and the nozzle releases the firefighting gas to the car, thereby extinguishing the fire of the car.

[0058] In order to adapt to different types of vehicles, when the fire extinguisher 1 is installed in different parking spaces, the fire extinguisher 1 can be set to different models to extinguish fires for different types of vehicles. For example, one model of fire extinguisher 1 is set for parking spaces for sedans and SUVs; another model of fire extinguisher 1 is set for parking spaces for buses and public buses, and different models of fire extinguisher 1 have different sizes.

[0059] like Figure 2 As shown, the fire bag cover 1 in this embodiment preferably includes an inflatable frame 11 and a fireproof wall 12, and the inflatable frame 11 includes a plurality of vertically arranged columns and a plurality of horizontally arranged beams. The columns and beams are combined to form a rectangular inflatable frame 11, so that the bottom of the frame is open for gas to enter the fire bag cover 1. Fireproof walls 12 are arranged between adjacent columns of the inflatable frame 11 and between adjacent beams. The fireproof wall 12 can be fixedly connected to the inflatable frame 11 by configuring sutures or the like.

[0060] In this embodiment, in order to ensure that the inflatable frame 11 is not damaged by burning, the outer surface of the inflatable frame 11 is wrapped with a fireproof layer, which plays a role in fire protection of the internal airbag. The fireproof layer can be a flame-retardant or non-combustible fire-resistant fiber fabric layer, and the fireproof layer is arranged on the surface of the inflatable frame 11 by bonding or other methods. The fireproof wall 12 of this embodiment can be a fire blanket of the prior art, and the fire blanket is preferably arranged in at least two layers, so as to achieve a better fireproof effect and prevent the fireproof wall 12 from being damaged.

[0061] Take an application scenario as an example: when a car is on fire, gas is filled into the inflatable frame 11, so that the frame is propped up into a rectangular frame shape. When the inflatable frame 11 is propped up into a rectangular frame shape, the inflatable frame 11 props up the fireproof wall 12. The inflatable frame 11 and the fireproof wall 12 cooperate to cover the burning car.

[0062] It should be noted that: in this embodiment, the entire fire bag cover 1 can be propped up by only inflating the inflatable frame 11. Obviously, compared with setting the entire fire bag cover 1 as an inflatable bag, the fire bag cover 1 structure of this embodiment can greatly reduce the deployment time of the fire bag cover, which is conducive to rapid fire extinguishing. Of course, in some other embodiments, if factors such as deployment time are not considered, the fire bag cover 1 can also be directly set as an integral bag.

[0063] Example 2

[0064] This embodiment provides a vehicle isolation fire extinguishing device, such as Figure 3As shown, it mainly includes a fire bag cover 1, an installation module 2, an inflation module 3, a fire module 4, a fire monitor 5 and a control module 6. The installation module 2, the inflation module 3, the fire module 4 and the fire monitor 5 are all connected to the control module 6 by signal, and the control module 6 can be an industrial computer module, a PLC module or other control modules 6 in the prior art.

[0065] In this embodiment, the installation module 2 is arranged above the parking space, and the installation module 2 can be installed on the ceiling above the parking space by configuring fasteners; or, a bracket can be arranged at the parking space, and then the installation module 2 is installed on the bracket, so that the installation module 2 is located above the parking space. The bracket can be a gantry or other brackets in the prior art.

[0066] The mounting module 2 of this embodiment is used to accommodate the fire bladder cover 1 in a contracted and folded state. When a car fire occurs, the mounting module 2 releases the fire bladder cover 1 downward, and the fire bladder cover 1 can cover the burning car. When the fire bladder cover 1 covers the burning car, the fire bladder cover 1 plays an isolating role, preventing the outside air from contacting the burning car, which is conducive to quickly extinguishing the flames.

[0067] like Figure 5 As shown, the installation module 2 in this embodiment specifically includes a storage box 21 and a release door 22. The storage box 21 can be a rectangular box, and the interior of the storage box 21 is used to accommodate the fire bag cover 1 in a contracted and folded state. The bottom of the storage box 21 is open, and a release door 22 is installed at the open position through a hinge, and the bottom of the storage box 21 can be opened or closed through the release door 22. The release door 22 is configured with an electronic lock. When the electronic lock is locked, the electronic lock can lock the release door 22, and the fire bag cover 1 is confined inside the storage box 21; when the electronic lock is unlocked, the release door 22 opens downward due to gravity, and the fire bag cover 1 contained in the storage box 21 is released downward.

[0068] It should be noted that: this embodiment discloses a structure of an installation module 2, but in some other embodiments, the installation module 2 may also adopt other structures in the prior art, and it is only necessary to ensure that the installation module 2 has the function of accommodating and releasing the fire bag cover 1.

[0069] like Figure 4 As shown, the fire bag cover 1 in this embodiment preferably includes an inflatable frame 11 and a fireproof wall 12, and the inflatable frame 11 includes a plurality of vertically arranged columns and a plurality of horizontally arranged beams. The columns and beams are combined to form a rectangular inflatable frame 11. The bottom of the inflatable frame 11 is open for cars to enter the fire bag cover 1. Fireproof walls 12 are arranged between adjacent columns of the inflatable frame 11 and between adjacent beams. The fireproof wall 12 can be fixedly connected to the inflatable frame 11 by configuring sutures or the like.

[0070] In this embodiment, in order to ensure that the inflatable frame 11 is not damaged by burning, the outer surface of the inflatable frame 11 is wrapped with a fireproof layer, which plays a role in fire protection for the internal airbag. The fireproof layer can be a flame retardant or non-combustible fire-resistant fiber fabric layer, and the fireproof layer is arranged on the surface of the inflatable frame 11 by bonding or other methods. The fireproof wall 12 of this embodiment can be a fire blanket of the prior art, and the fire blanket is preferably arranged with at least two layers, so as to achieve a better fireproof effect and prevent the fireproof wall 12 from being damaged.

[0071] Take an application scenario as an example: when a car is on fire, gas is filled into the inflatable frame 11, and the inflatable frame 11 expands and supports to form a rectangular frame shape. When the inflatable frame 11 is propped up into a rectangular frame shape, the inflatable frame 11 props up the fireproof wall 12. Then the inflatable frame 11 and the fireproof wall 12 cooperate to cover the burning car, reducing the contact between the outside air and the burning car.

[0072] like Figure 6 As shown, in this embodiment, the inflation module 3 specifically includes a gas container 31, a valve 32 and a fixing frame 33. The gas container 31 is preferably a gas cylinder, and firefighting gas is stored inside the gas cylinder. The types of firefighting gas include but are not limited to carbon dioxide, IG541, heptafluoropropane, perfluorohexanone, nitrogen, argon or helium. The gas cylinder is preferably configured as at least two to ensure sufficient firefighting gas supply. The gas container 31 is fixedly mounted on the fixing frame 33 to ensure that the gas container 31 will not fall. The fixing frame 33 can be installed in a position such as a garage wall by configuring fasteners. The fixing frame 33 can be a rectangular frame formed by a combination of several columns and beams. The valve 32 is preferably an electric valve 32, so as to facilitate signal control. The valve 32 is installed at the mouth of the gas container 31. When the valve 32 is opened, the gas in the gas container 31 can be transported to the firefighting bag cover 1. The gas container 31 is specifically in a connected state with the firefighting bag cover 1 through a pipeline, and the pipeline is preferably a plastic pipeline. The pipeline can be dragged and moved so that when the firefighting bag cover 1 is released downward, the pipeline and the firefighting bag cover 1 will not separate.

[0073] like Figure 4As shown, the fire-fighting module 4 in this embodiment includes a releaser 41 and a pressure monitor 42. The releaser 41 is preferably a nozzle, which is arranged on the inner wall of the fire-fighting bag cover 1, and the nozzle is in a connected state with the fire-fighting bag cover 1. That is, the fire-fighting gas inside the fire-fighting bag cover 1 can be released to the car through the nozzle, thereby extinguishing the fire of the car. There are multiple nozzles, and they are arranged in a ring shape for at least one circle. By arranging the nozzle in a ring shape, it can be ensured that the fire-fighting gas is in full contact with the burning car. The pressure monitor 42 of this embodiment is arranged on the fire-fighting bag cover 1, and the pressure monitor 42 is used to detect the internal pressure of the fire-fighting bag cover 1. The pressure monitor 42 can be a pressure detection device in the prior art. The pressure monitor 42 and the nozzle are both in a signal connection state with the control module 6.

[0074] Take an application scenario as an example: when the pressure monitor 42 detects that the internal air pressure of the fire bag cover 1 reaches a certain threshold (the fire bag cover 1 is in a stable state at this time), the control module 6 can control the releaser 41 to open, and the releaser 41 releases the fire gas to the car to extinguish the fire of the car.

[0075] In order to detect whether the car is on fire, the present embodiment also includes a fire monitor 5 arranged outside, which can be specifically arranged in a corresponding parking space (for example, on the wall of the parking space). The fire monitor 5 can be a detection device used in the prior art to detect whether a fire has occurred. The detection device can determine whether a car is on fire by detecting one or more of temperature, smoke and flame light. When the fire monitor 5 detects that the car is on fire, the fire monitor 5 feeds back a signal to the control module 6, and the control module 6 controls the valve 32 to open, so that the gas cylinder can inflate the fire bag cover 1.

[0076] Example 3

[0077] The difference between this embodiment and embodiment 2 lies in the difference of fire fighting module 44. Figure 8 and Fig. 9 As shown, the fire module 44 includes a release component 43, a spring 44 and a closing plug 45. The release component 43 is installed on the inner wall of the fire bag cover 1. The release component 43 is constructed with a release channel that runs through the entire release component 43. The release channel enables the interior of the fire bag cover 1 to communicate with the outside. The closing plug 45 and the spring 44 are installed inside the release channel. The closing plug 45 is located at the entrance of the connecting channel. The spring 44 can hold the closing plug 45 against the closing plug 45, so that the closing plug 45 closes the entrance of the release channel. At the same time, when the internal air pressure of the fire bag cover 1 increases, the closing plug 45 is pushed by the fire gas, the closing plug 45 moves, and the closing plug 45 opens the entrance of the connecting channel, and the fire gas can be released to the outside through the connecting channel.

[0078] Take an application scenario as an example: when the fire bag cover 1 is inflated, in the initial stage, since the internal air pressure of the fire bag cover 1 is relatively small, the spring 44 will press the closing plug 45, and the closing plug 45 will close the connecting channel, thereby preventing the fire gas from leaking and causing the fire bag cover 1 to be unable to prop up normally; as the fire gas continues to inflate the fire bag cover 1, the internal air pressure of the fire bag cover 1 increases to a threshold value, and the fire gas pushes the closing plug 45 to move, and the closing plug 45 opens the connecting channel, and the fire gas in the fire bag cover 1 is released to the burning car through the connecting channel.

[0079] Example 4

[0080] This embodiment is improved on the basis of embodiment 2. Since some cars catch fire while being charged, a charging cable may be connected to the car. When the charging cable is connected to the car, the charging cable may prevent the fire bag cover 1 from covering the car. Therefore, in this embodiment, a notch is preferably provided at the rear end of the fire bag cover 1, and the notch shape may be rectangular. The notch is used to accommodate the charging cable.

[0081] Take an application scenario as an example: when a car in a charging state catches fire, the installation module 2 releases the fire bag cover 1 downward. When the fire bag cover 1 is released downward, the fire bag cover 1 covers the burning car. At the same time, the charging cable is also accommodated in the gap, thereby preventing the charging cable from pressing against the fire bag cover 1.

[0082] Example 5

[0083] This embodiment is improved on the basis of embodiment 2 or embodiment 4. In order to ensure that the fire bag cover 1 is more stable. In this embodiment, a circle of accommodating channels is preferably provided at the bottom of the fire bag cover 1, and the accommodating channels are used to accommodate weights. For example, the accommodating channels can accommodate water or sand, and in this embodiment, the weight is preferably sand.

[0084] Take an application scenario as an example: when the fire bag cover 1 is released downward, since a circle of accommodating channels is set at the bottom of the accommodating channels, and a counterweight is contained in the accommodating channels, during the downward release of the fire bag cover 1, the bottom of the fire bag cover 1 will naturally be located at the bottom due to gravity, and eventually the bottom of the fire bag cover 1 will contact the ground. At the same time, after the bottom of the fire bag cover 1 contacts the ground, since a counterweight is set at the bottom of the fire bag cover 1, the bottom of the fire bag cover 1 is heavier, the fire bag cover 1 is more stable, and the fire bag cover 1 is not easy to be overturned.

[0085] It should be noted that: if a notch is provided at the rear end of the fire bag cover 1, the accommodating channel provided at the bottom of the fire bag cover 1 is not a complete ring, and the accommodating channel is also correspondingly disconnected at the notch. That is, the accommodating channel is in the shape of an open ring. When the accommodating channel is in the shape of an open ring, and a counterweight is provided in the accommodating channel, the counterweight drives the bottom of the fire bag cover 1 to fall downward, and the counterweight can adjust the position of the fire bag cover 1, and the charging cable can slide into the notch to ensure that the notch position at the rear end of the fire bag cover 1 is adapted to the position of the charging cable.

[0086] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
