Description

Technical Field

[0001] This invention relates to the field of electrical equipment safety protection technology, and in particular to a fireproof distribution box. Background Technology

[0002] As the core equipment for power distribution, distribution boxes are widely used in various buildings and industrial facilities. With the increase in the load of electrical equipment and the increasing complexity of the power environment, fire accidents caused by short circuits, overloads and other reasons in distribution boxes occur frequently.

[0003] Currently, the fire resistance of distribution boxes on the market is mainly achieved through external fire protection systems or simple insulation materials. However, these methods have problems such as delayed response and limited protection range. Moreover, when a fire breaks out inside the distribution box due to leakage, short circuit, or overload, it is difficult for staff to detect it at first. Often, the fire is only noticed when it has grown large, at which point the distribution box is already severely damaged, and it can ignite flammable materials around the distribution box, such as transformers, thus causing a fire.

[0004] In response to the aforementioned technologies, there is an urgent need to design and develop a fireproof distribution box that can immediately extinguish the fire when the wires inside the distribution box catch fire due to leakage, short circuit or overload, thus preventing more serious losses. Summary of the Invention

[0005] In order to enable immediate fire extinguishing operations at the point of ignition when the wires inside the distribution box catch fire due to leakage, short circuit or overload, and to avoid more serious losses, this application provides a fireproof distribution box.

[0006] The fireproof distribution box provided in this application adopts the following technical solution: A fireproof distribution box includes a judgment mechanism for determining fire point information within the distribution box. The distribution box is equipped with a fire extinguishing mechanism, which includes a first fire extinguishing head slidably disposed horizontally within the distribution box, a second fire extinguishing head slidably disposed vertically within the distribution box, a fire extinguishing device for providing fire extinguishing material to the first and second fire extinguishing heads, and a control component for controlling the activation and deactivation of the fire extinguishing device. The judgment mechanism is located on the inner top wall of the distribution box, and the fire extinguishing device is located beside the distribution box.

[0007] By adopting the above technical solution, the judgment mechanism is set on the inner top wall of the distribution box, the first fire extinguishing head is slidably installed horizontally inside the distribution box, the second fire extinguishing head is slidably installed vertically inside the distribution box, and the fire extinguishing device is set next to the distribution box. The fire extinguishing device provides fire extinguishing material to the first and second fire extinguishing heads. When the judgment mechanism identifies the location of the fire point inside the distribution box, it drives the first fire extinguishing head to slide horizontally to the position closest to the fire point, and drives the second fire extinguishing head to slide vertically to the position closest to the fire point. The control component activates the fire extinguishing device to provide fire extinguishing material to the first and second fire extinguishing heads, so that the first and second fire extinguishing heads can spray fire extinguishing material on the fire point in a timely and accurate manner to extinguish the fire and avoid more serious losses.

[0008] Preferably, the control component includes a valve disposed at the output end of the fire extinguishing device, a movable pin cooperating with the valve, a pulling member for pulling the movable pin, and a driving member for driving the pulling member to move. The movable pin is disposed on the valve, and the driving member and the pulling member are disposed next to the distribution box.

[0009] By adopting the above technical solution, the valve is set at the output end of the fire extinguishing device, the movable pin is set on the valve, the movable pin cooperates with the valve, and the driving component and the pulling component are set next to the distribution box. When it is necessary to start the fire extinguishing device, the driving component drives the pulling component to slide, so that the pulling component drives the movable pin to disengage from the valve, which facilitates the start of the fire extinguishing device.

[0010] Preferably, the fire extinguishing mechanism includes a first material transfer pipe connected to the first fire extinguishing head, a second material transfer pipe connected to the second fire extinguishing head, a material feeding pipe that can be connected to the fire extinguishing device, and a control component for controlling the connection between the material feeding pipe and the first and second material transfer pipes, wherein the control component is disposed on the material feeding pipe.

[0011] By adopting the above technical solution, the feed pipe is connected to the fire extinguishing device, and the control component is installed on the feed pipe. The first feed pipe is connected to the first fire extinguishing head, and the second feed pipe is connected to the second fire extinguishing head. When the judgment mechanism detects a fire in the distribution box, it first adjusts the control component to connect the feed pipe to the first and second feed pipes. Then, the fire extinguishing device is activated to deliver the extinguishing material to the first and second fire extinguishing heads through the feed pipe, the first feed pipe, and the second feed pipe. If there is no fire in the distribution box, and the fire is pulled... If the actuator accidentally pulls the movable pin off the valve due to force majeure, the control component will not regulate the connection between the feed pipe and the first and second feed pipes, so that the first and second extinguishing heads will not spray extinguishing material. This reduces the possibility of the actuator being accidentally activated and causing the movable pin to disengage from the valve. If it is necessary to extinguish the fire through the first and second extinguishing heads later, the control component can be used to regulate the connection between the feed pipe and the first and second feed pipes, so that the first and second extinguishing heads can complete the fire extinguishing task.

[0012] Preferably, a connecting mechanism is provided between the fire extinguishing device and the feed pipe. The connecting mechanism includes a connecting pipe that can be threadedly connected to the discharge port of the fire extinguishing device, and the connecting pipe is rotatably sleeved on the feed pipe.

[0013] By adopting the above technical solution, the connecting pipe is threadedly connected to the outlet pipe of the fire extinguishing device. The connecting pipe is rotatably sleeved on the feed pipe. When the fire extinguishing device needs to be replaced, the connecting pipe is rotated to detach it from the fire extinguishing device. After replacing the fire extinguishing device, the connecting pipe is rotated again to connect to the new fire extinguishing device, which facilitates the replacement of the fire extinguishing device.

[0014] Preferably, the connecting mechanism includes a support ring disposed on the feed pipe, a sealing ring that can abut against the support ring, and a compression ring for compressing the sealing ring. The support ring is connected to the feed pipe, the sealing ring is disposed on the connecting pipe and is connected to the connecting pipe, the sealing ring and the connecting pipe are sleeved on the support ring, and the compression ring is vertically slidably disposed on the feed pipe.

[0015] By adopting the above technical solution, the support ring is set on the feed pipe and connected to the feed pipe. The sealing ring is set on the connecting pipe and connected to the connecting pipe. The sealing ring and the connecting pipe are sleeved on the support ring. The compression ring is vertically slidably set on the feed pipe. During the process of connecting the connecting pipe to the fire extinguishing device, one end of the connecting pipe is threaded to the output end of the fire extinguishing device. The compression ring is rotated to approach the sealing ring, so that the sealing ring is tightly attached to the support ring, which improves the tightness of the connection between the connecting pipe and the feed pipe, reduces the possibility of fire extinguishing material leakage during the fire extinguishing process, and improves the safety of the fire extinguishing device during the fire extinguishing process.

[0016] Preferably, the judgment mechanism includes a first identification component for judging whether there is a fire point and a second identification component for judging the location of the fire point, wherein the first identification component and the second identification component are disposed on the inner top wall of the distribution box.

[0017] By adopting the above technical solution, the first identification component and the second identification component are installed on the inner top wall of the distribution box. The first identification component can determine whether there is a fire point, and the second identification component can determine the location of the fire point, which facilitates timely determination of the fire point information and thus facilitates accurate fire extinguishing.

[0018] Preferably, the distribution box is installed inside the protective box, the fire extinguishing device is installed inside the protective box, and a processing unit is installed inside the protective box. The processing unit can receive the data collected by the first identification component and the second identification component, and the processing unit can control the operation of the control component and the drive component. The processing unit can also control the sliding of the first fire extinguishing head and the second fire extinguishing head.

[0019] By adopting the above technical solution, the power distribution box is installed inside the protective box, the fire extinguishing device is installed inside the protective box, and a processing unit is installed inside the protective box. The processing unit can receive the data collected by the first identification component and the second identification component, and the processing unit can control the operation of the control component and the drive component. The processing unit can control the sliding of the first fire extinguishing head and the second fire extinguishing head. The processing unit is installed outside the power distribution box, so when the power distribution box catches fire, it will not affect the processing unit's function of receiving data and controlling the fire extinguishing.

[0020] Preferably, a protective window is hinged inside the side window of the protective box, and a waterproof mechanism is provided on the protective box. The waterproof mechanism includes a rainproof component provided on the outer top surface of the protective box and a rubber sealing ring provided on the inner wall of the window of the protective box. The protective window can abut against the rubber sealing ring.

[0021] By adopting the above technical solution, the rainproof component is installed on the top surface of the protective box, and a protective window is hinged inside the side window of the protective box. The rubber sealing ring is installed on the inner wall of the window of the protective box, and the protective window can abut against the rubber sealing ring. During the rainy season, the rainproof component and the rubber sealing ring can prevent rainwater from entering the protective box, thereby preventing rainwater from entering the distribution box and reducing the possibility of short circuits caused by rainwater erosion in the distribution box, which could lead to leakage and fire.

[0022] Preferably, the inner wall of the protective box is coated with fire-retardant paint, and the electrical distribution box is filled with fire-retardant paint.

[0023] By adopting the above technical solution, the inner wall of the protective box is coated with fire-retardant paint, and the electrical distribution box is filled with fire-retardant paint. When the fire-retardant paint is exposed to fire, it will form a heat insulation layer through physical and chemical reactions, thus delaying the spread of fire.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The judgment mechanism is located on the inner top wall of the distribution box. Fire extinguishing head one is horizontally slidable inside the distribution box, and fire extinguishing head two is vertically slidable inside the distribution box. The fire extinguishing device is located next to the distribution box. The fire extinguishing device provides fire extinguishing material to fire extinguishing head one and fire extinguishing head two. When the judgment mechanism identifies the location of the fire point inside the distribution box, it drives fire extinguishing head one to slide horizontally to the position closest to the fire point and drives fire extinguishing head two to slide vertically to the position closest to the fire point. The control component activates the fire extinguishing device to provide fire extinguishing material to fire extinguishing head one and fire extinguishing head two, so that fire extinguishing head one and fire extinguishing head two can extinguish the fire point in a timely and accurate manner, avoiding more serious losses. 2. The feed pipe is connected to the fire extinguishing device, and the control element is located on the feed pipe. The first feed pipe is connected to the first fire extinguishing head, and the second feed pipe is connected to the second fire extinguishing head. When the judgment mechanism detects a fire in the distribution box, it first adjusts the control element to connect the feed pipe to the first and second feed pipes. Then, the fire extinguishing device is activated to deliver the extinguishing material to the first and second fire extinguishing heads through the feed pipe, the first feed pipe, and the second feed pipe. If there is no fire in the distribution box, and the pulling element is not activated... In the event of accidental activation of the movable pin from the valve due to force majeure, the control component will not regulate the connection between the feed pipe and the first and second feed pipes, thus preventing the first and second extinguishing heads from spraying extinguishing material. This reduces the possibility of the movable pin disengaging from the valve due to accidental activation of the pull component. If it is necessary to extinguish the fire using the first and second extinguishing heads later, the control component can be used to re-regulate the connection between the feed pipe and the first and second feed pipes, allowing the first and second extinguishing heads to complete their fire extinguishing tasks. 3. The connecting pipe is threaded to the outlet of the fire extinguishing device. The connecting pipe is rotatably sleeved on the feed pipe. When the fire extinguishing device needs to be replaced, the connecting pipe is rotated to detach it from the fire extinguishing device. After replacing the fire extinguishing device, the connecting pipe is rotated again to connect to the new fire extinguishing device, which facilitates the replacement of the fire extinguishing device.

[0046] Reference Figure 1 and Figure 2 As shown, when the first identification component 41 identifies a fire in the distribution box 2 and the second identification component 42 identifies the location of the fire, the processing unit 12 controls the opening of the electronic control valve 5101, and the feed pipe 513 is connected to the first feed pipe 511 and the second feed pipe 512. The processing unit 12 drives the first motor 51 to drive the first screw 52 to rotate. Under the limiting action of the first slider 53, the first fire extinguishing head 54 slides horizontally to the position closest to the fire. The processing unit 12 drives the second motor 55 to drive the second screw 56 to rotate. Under the limiting action of the second slider 57, the second fire extinguishing head 58 slides vertically to the position closest to the fire. Reference Figure 1 and Figure 2 As shown, the processing unit 12 drives the driving component 5104 to move the pulling component 5103, causing the pulling component 5103 to move the movable pin 5102 away from the valve 5101, activating the fire extinguishing device 59.

[0047] Reference Figure 1 and Figure 2As shown, if the pull member 5103 accidentally pulls the movable pin 5102 off the valve 5101 due to force majeure when there is no fire in the distribution box 2, the control member 514 will not regulate the connection between the feed pipe 513 and the first feed pipe 511 and the second feed pipe 512, so that the first fire extinguishing head 54 and the second fire extinguishing head 58 will not spray fire extinguishing material, reducing the possibility that the pull member 5103 will be accidentally touched, causing the movable pin 5102 to disengage from the valve 5101. If it is necessary to extinguish the fire through the first fire extinguishing head 54 and the second fire extinguishing head 58 later, the control member 514 can continue to regulate the connection between the feed pipe 513 and the first feed pipe 511 and the second feed pipe 512, so that the first fire extinguishing head 54 and the second fire extinguishing head 58 can complete the fire extinguishing task.

[0048] The implementation principle of a fireproof distribution box 2 in this application embodiment is as follows: When the first identification component 41 identifies a fire inside the distribution box 2 and the second identification component 42 identifies the location of the fire, the processing unit 12 controls the opening of the electronic control valve 5101, and the feed pipe 513 is connected to the first feed pipe 511 and the second feed pipe 512. The processing unit 12 drives the first motor 51 to rotate the first screw 52. Under the limiting action of the first slider 53, the first fire extinguishing head 54 slides laterally to the position closest to the fire. The processing unit 12 drives the second motor 55 to rotate the second screw 56. Under the limiting action of the second slider 57, the second fire extinguishing head 58 slides vertically to the position closest to the fire. The processing unit 12 drives the driving component 5104 to slide the pulling component 5103, causing the pulling component 5103 to drive the movable pin 5102 to disengage from the valve 5101, thus activating the fire extinguishing device 59. The fire extinguishing device 59 delivers the fire extinguishing material to the first fire extinguishing head 54 and the second fire extinguishing head 58 through the feed pipe 513, the first feed pipe 511, and the second feed pipe 512. The fire extinguishing device 59 provides the fire extinguishing material to the first fire extinguishing head 54 and the second fire extinguishing head 58, enabling the first fire extinguishing head 54 and the second fire extinguishing head 58 to spray the fire extinguishing material at the fire point in a timely and accurate manner to extinguish the fire and avoid more serious losses. If the pull member 5103 accidentally pulls the movable pin 5102 off the valve 5101 due to force majeure when there is no fire in the distribution box 2, the control member 514 will not regulate the connection between the feed pipe 513 and the first feed pipe 511 and the second feed pipe 512, so that the first fire extinguishing head 54 and the second fire extinguishing head 58 will not spray fire extinguishing material, reducing the possibility that the pull member 5103 will be accidentally activated and cause the movable pin 5102 to disengage from the valve 5101. If it is necessary to extinguish the fire through the first fire extinguishing head 54 and the second fire extinguishing head 58 later, the control member 514 can continue to regulate the connection between the feed pipe 513 and the first feed pipe 511 and the second feed pipe 512, so that the first fire extinguishing head 54 and the second fire extinguishing head 58 can complete the fire extinguishing task.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
