Description

Technical Field

[0001] This utility model relates to the field of fire prevention and control device technology, and in particular to a fire prevention and control isolation compartment for electric vehicles. Background Technology

[0002] With the increasing popularity of electric vehicles, the fire risk posed by their power batteries is becoming increasingly prominent. Electric vehicle fires are characterized by intense combustion and the production of toxic fumes, posing a serious threat to people and property. Effective prevention and control have become an important issue in the field of fire protection.

[0003] To address this challenge, existing technologies have developed multi-section fire prevention isolation compartments for electric vehicles. This design allows the isolation compartments to retract and fold when not in use, saving space; when needed, they can be unfolded to form a physical isolation space and control the spread of fire.

[0004] However, most fire isolation chambers currently rely on manual deployment, which is not only time-consuming and labor-intensive, but also delays precious firefighting opportunities, especially in emergency situations. Secondly, existing fire isolation chambers generally lack smoke extraction capabilities. The combustion of electric vehicles produces a large amount of high-temperature, soot-filled smoke, which accumulates in the closed or semi-closed fire isolation chamber, reducing visibility and hindering firefighting operations.

[0005] Based on this, in order to further improve the ease of use of existing isolation compartments, we propose an electric vehicle fire prevention isolation compartment. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as reliance on manual deployment which is time-consuming and labor-intensive, and to propose an electric vehicle fire prevention isolation compartment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design an electric vehicle fire prevention isolation compartment, including:

[0009] Several nested and sliding chambers;

[0010] A drive unit is installed between each pair of said compartments, the drive unit being used to drive relative movement between the two said compartments;

[0011] The interior of the compartment is equipped with a water system and a fire extinguisher, and the outermost and innermost ends of the two compartments are also equipped with roller shutter assemblies.

[0012] Furthermore, the compartment is provided in three parts, nested sequentially;

[0013] The compartment has a U-shaped structure and is equipped with a set of wheels at the bottom;

[0014] A smoke exhaust water gun is also installed above the silo.

[0015] Furthermore, the water system assembly includes a surface water pipe and a top water pipe fixedly installed inside the chamber. The surface water pipe and the top water pipe are connected in water passage and have spray holes evenly distributed on their end faces. A connector is fixedly installed on the side of the chamber and is connected to the surface water pipe.

[0016] Furthermore, the roller shutter assembly includes a fireproof curtain fixedly installed at the end of the compartment, and a strap is fixedly installed on the end face of the fireproof curtain, with a buckle at the end of the strap;

[0017] A buckle is fixedly installed on the top of the hopper body, and the buckle ring is fitted onto the buckle.

[0018] Furthermore, it also includes locking components;

[0019] The locking component is used to lock and position the plurality of compartments when they are being stored.

[0020] Furthermore, the locking assembly includes a sleeve fixedly installed on the outermost compartment, a locking rod being movably inserted into the sleeve via a spring, and positioning holes being provided on the end face of the inner compartment, with the locking rod sequentially passing through and being inserted into multiple positioning holes.

[0021] Furthermore, the driving component is configured as a hydraulic cylinder, the housing of which is mounted on the inner side of the chamber and the shaft end is connected to the outer side of the chamber.

[0022] The present invention proposes an electric vehicle fire prevention isolation compartment, which has the following advantages: Firstly, by using a driving component to move the two compartments together, the compartment can automatically unfold during use, thus improving fire extinguishing efficiency.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-5 As one embodiment of this utility model, a fire prevention isolation compartment for electric vehicles is disclosed. Specifically, the isolation compartment includes several compartment bodies 1 that are sequentially nested and slidable. In this embodiment, three compartment bodies 1 are provided and are sequentially nested. The compartment bodies 1 have a U-shaped structure. Preferably, in this embodiment, two compartment bodies 1 can be slidably engaged by a guide rail and a slider assembly to ensure the stability of the sliding.

[0031] Of course, in order to facilitate the convenient movement of each compartment 1, and with wheelset 11 installed at the bottom, the wheelset 11 can be designed as directional wheels. Specifically, four wheelset 11 are installed under each compartment 1.

[0032] A drive unit 2 is installed between each two compartments 1, and the drive unit 2 is used to drive the two compartments 1 to move relative to each other.

[0033] Inside the compartment 1, a water system assembly 3 and a fire extinguisher 4 are fixedly installed. It is worth noting that in this embodiment, there is a certain height difference between the outer compartment 1 and the inner compartment 1. This design is for the installation of the drive component 2 and the fire extinguisher 4. In this way, when multiple compartments 1 are stored, the drive component 2 and the fire extinguisher 4 are prevented from interfering with the movement of the inner compartment 1. In addition, it should be noted that the fire extinguisher 4 in this embodiment is a suspended automatic fire extinguisher, which realizes automatic spraying of extinguishing medium through a temperature sensing element. Its specific principle is existing technology and will not be elaborated here. Of course, in order to seal the two ends of the unfolded isolation compartment, in this embodiment, a roller shutter assembly 5 is also installed at the ends of the two outermost and innermost compartments 1.

[0034] Preferably, considering that smoke will be generated during the fire extinguishing process, in order to exhaust the smoke inside the compartment 1, a smoke exhaust water gun 12 is also installed above the compartment 1 in this embodiment. Through the design of the smoke exhaust water gun 12, the smoke inside the compartment 1 can be quickly exhausted during fire extinguishing, thereby improving the fire extinguishing stability of electric vehicles.

[0035] The principle of the exhaust water gun 12 is to generate high-speed jets through high-pressure water flow, and use the impact force of the water flow to form an airflow that drives the air flow, thereby dispersing the smoke and reducing its concentration. Its specific structure and principle are existing technologies and will not be elaborated here. Of course, the exhaust water gun 12 can also be connected to an external water pump through a pipe. For details, please refer to the connection method of the water circuit component 3 below.

[0036] In some embodiments, the water circuit assembly 3 of the present invention includes a surface water pipe 31 and a top water pipe 32 fixedly installed inside the chamber 1. The surface water pipe 31 and the top water pipe 32 are connected by water circuit and have spray holes evenly distributed on their end faces. A connector 33 is fixedly installed on the side of the chamber 1 and is connected to the surface water pipe 31.

[0037] Specifically, in this embodiment, since the compartment 1 has a U-shaped structure, two surface water pipes 31 are provided. The two surface water pipes 31 and the top water pipe 32 are arranged in a U-shaped structure to form a 270-degree water spray for fire extinguishing of the electric vehicle. In actual use, after each compartment 1 is unfolded in sequence, an external water source can be connected through the connector 33, thus forming a water channel inside the compartment 1. Water is sprayed outward along the spray holes to extinguish the fire. Of course, in other embodiments, nozzles can also be installed on the surface water pipes 31 and the top water pipe 32 for water spraying. The specific method can be selected by those skilled in the art, and will not be elaborated here.

[0038] Preferably, in this embodiment, the roller shutter assembly 5 includes a fireproof curtain 51 fixedly installed at the end of the compartment 1, and a strap 52 is fixedly installed on the end face of the fireproof curtain 51, with a buckle 53 provided at the tail end of the strap 52.

[0039] A buckle 54 is fixedly installed above the chamber body 1, and the buckle ring 53 is fitted onto the buckle 54.

[0040] During fire extinguishing, the buckle 53 can be removed from the buckle seat 54, which is roughly U-shaped. The buckle 53 is fastened in the opening of the buckle seat 54. When the buckle 53 is removed, the entire fire curtain 51 falls freely under the action of gravity, thus achieving the sealing operation of the opening sides of the two end chambers 1. Conversely, the entire fire curtain 51 can be rolled up, and then the buckle 53 can be hooked onto the buckle seat 54 to complete the rolling up of the fire curtain 51.

[0041] In some embodiments, the present invention also includes a locking component 6;

[0042] The locking component 6 is used to lock and position the plurality of compartments 1 when they are being stored.

[0043] Specifically, in this embodiment, the locking component 6 includes a sleeve 61 fixedly installed on the outermost compartment 1. A locking rod 63 is movably inserted into the sleeve 61 via a spring 62. The two ends of the spring 62 are fixed to the sleeve 61 and the locking rod 63. Positioning holes 64 are provided on the end face of the inner compartment 1. The locking rod 63 passes through and is inserted into a plurality of positioning holes 64 in sequence.

[0044] When the three compartments 1 are stored, in order to ensure the stability of the storage position and reduce the force on the drive component 2 during movement, the present invention uses locking rods 63 to lock the multiple compartments 1 in sequence by inserting them together, so as to ensure the relative locking between the compartments 1. Of course, when unfolding the isolation compartment, the locking rods 63 should be opened first to ensure that each compartment 1 can move and unfold stably.

[0045] It should be noted that the driving component 2 in this embodiment is a hydraulic cylinder. Preferably, the hydraulic cylinder in this embodiment can be a multi-stage hydraulic cylinder. The housing of the hydraulic cylinder is installed on the inner side of the chamber 1 and the shaft end is connected to the outer side of the chamber 1. The inner side and the outer side refer to the inner and outer sides of the two chambers 1. The design of installing the housing of the hydraulic cylinder on the inner chamber 1 can reduce the heat of the housing during fire extinguishing, thus ensuring its working stability.

[0046] In summary, this utility model utilizes a driving component 2 to drive the movement between the two compartments 1, enabling automatic deployment of the two compartments 1 during the entire use of the isolation compartment, thereby improving fire extinguishing efficiency. Furthermore, each compartment 1 is equipped with a smoke exhaust nozzle 12, which can quickly expel smoke from inside the compartment 1 during fire extinguishing, thus enhancing the fire extinguishing stability for electric vehicles. Finally, a locking component 6 locks and secures the multiple compartments 1 during storage, ensuring the stability of their storage positions and reducing the stress on the driving component 2 during movement.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
