Description

Technical Field

[0001] This invention relates to the field of electrical safety technology, specifically to an electrical automation industrial fire extinguishing device. Background Technology

[0002] Electrical engineering is a general term encompassing the disciplines or engineering fields of electrical energy production, transmission, distribution, use, and the manufacturing of electrical equipment. It is a science that uses electrical energy, electrical equipment, and electrical technology to create, maintain, and improve a defined space and environment. It covers three aspects: the conversion, utilization, and research of electrical energy, including basic theory, applied technology, and facilities and equipment. Electrical engineering is one of the core disciplines in modern science and technology, and an indispensable key discipline in today's high-tech fields. It is the tremendous progress in electronic technology that has driven the arrival of the information age based on computer networks, and will change the way people live and work.

[0003] Currently, existing industrial electrical equipment is typically protected by protective enclosures to prevent damage. However, in the event of a fire, these enclosures usually cannot extinguish the fire themselves and require human intervention. By the time personnel discover and arrive at the scene, the fire may be uncontrollable. While some electrical cabinets have fire suppression systems, these typically require a power source to activate. In the event of a fire in one of these cabinets, a power outage can easily prevent the fire suppression system from functioning properly. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an electrical automation industrial fire extinguishing device to solve the problem that existing electrical boxes usually do not have the effect of self-extinguishing fires, and although there are some electrical cabinets with fire extinguishing functions, they still require power support to trigger the fire extinguishing function.

[0005] This invention is achieved through the following technical solution:

[0006] An electrical automation industrial fire extinguishing device includes an electrical cabinet, in which a fixing plate for supporting electrical components is provided. One end of the fixing plate is fixedly connected to the inner wall of the electrical cabinet. At least one side of the electrical cabinet has a heat dissipation vent. A movable plate is slidably fitted inside the heat dissipation vent. The movable plate can slide along the through direction of the heat dissipation vent and move closer to or away from the heat dissipation vent.

[0007] Inside the electrical cabinet, below the fixed plate, there is a support member made of a fusible material. The top surface of the support member is provided with a counterweight. A first connecting rod is provided between the counterweight and the movable plate, and the two ends of the first connecting rod are respectively connected to the counterweight and the movable plate.

[0008] Further specified, the top surface of the electrical cabinet is provided with a container for storing dry powder, and the bottom surface of the container and the top surface of the electrical cabinet are connected through a connection port, and the interior of the container and the electrical cabinet are connected through two connection ports;

[0009] A baffle is slidably fitted inside the connection port of the electrical cabinet. A second connecting rod is provided between the baffle and the first connecting rod. The two ends of the second connecting rod are respectively hinged to the bottom surface of the baffle and the first connecting rod.

[0010] Further specified, a support membrane is provided inside the connection port of the container, and the support membrane covers the connection port;

[0011] The container is connected to a pressure pump, and the output end of the pressure pump is connected to the inside of the container.

[0012] Furthermore, the electrical cabinet is also equipped with a tapping assembly, which is located between the electrical components and the connection port. The tapping assembly is rotatably connected to the electrical cabinet, and the rotation path of the tapping assembly is perpendicular to the through direction of the connection port.

[0013] Further defined, the striking assembly includes multiple rods and multiple collars arranged along the length of the rods. One end of each rod is rotatably connected to the electrical cabinet, and the collars are rotatably sleeved on the rods. Each of the opposite ends of the collars is provided with a flip plate.

[0014] Further defined, the movable plate includes a plate body and a frame body, the frame body is slidably engaged with the heat dissipation vent, and the plate body is fixed on the side of the frame body away from the heat dissipation vent;

[0015] The frame has guide grooves on opposite sides, the guide grooves extend along the groove direction of the heat dissipation groove, and guide blocks are provided on opposite sides of the heat dissipation groove within the guide grooves.

[0016] Furthermore, the electrical cabinet has a sealing groove on its side wall that surrounds the heat dissipation vent, and a sealing ring is provided on the side of the plate near the heat dissipation vent. The sealing groove is located at the end of the sliding path of the plate.

[0017] Furthermore, the frame has through holes on its side walls.

[0018] Furthermore, the electrical cabinet is also provided with a base located below the counterweight, and the top surface of the base is provided with a groove recessed along the thickness direction of the base, and the support member is placed in the groove.

[0019] Furthermore, a heat-conducting rod is provided between the base and the fixing plate, and the two ends of the heat-conducting rod are detachably connected to the fixing plate and the base, respectively.

[0020] The beneficial effects of this invention are as follows:

[0021] A fire in an electrical component causes the internal temperature of the electrical cabinet to rise. The support components will gradually melt due to the high temperature environment. The counterweight placed on the support components will fall due to gravity after losing the support. As it falls, it will pull the first connecting rod, which will then pull the movable plate towards the heat dissipation vent until the movable plate is in contact with the heat dissipation vent and covers it. This will prevent outside air from entering the electrical cabinet through the heat dissipation vent, thereby reducing the air circulation inside the electrical cabinet and reducing the amount of oxygen inside the electrical cabinet.

[0022] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0035] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0036] Please see Figure 1-6 The present invention provides a technical solution: an electrical automation industrial fire extinguishing device, including an electrical cabinet 1, wherein a fixing plate 101 for supporting electrical components is provided inside the electrical cabinet 1, one end of the fixing plate 101 is fixedly connected to the inner wall of the electrical cabinet 1, and a heat dissipation vent 102 is provided through at least one side of the electrical cabinet 1, wherein a movable plate 2 is slidably fitted inside the heat dissipation vent 102, and the movable plate 2 can slide along the through direction of the heat dissipation vent 102 and move closer to or away from the heat dissipation vent 102;

[0037] Inside the electrical cabinet 1, below the fixed plate 101, there is a support member 3 made of a fusible material. The top surface of the support member 3 is provided with a counterweight 4. A first connecting rod 401 is provided between the counterweight 4 and the movable plate 2. The two ends of the first connecting rod 401 are respectively connected to the counterweight 4 and the movable plate 2.

[0038] In this solution, when the electrical cabinet 1 is in normal use, the interior can be connected to the outside through the heat dissipation vent 102. At this time, the movable plate 2 moves away from the heat dissipation vent 102 to keep the heat dissipation vent 102 open. At the same time, the movable plate 2 can also slide to fit against the heat dissipation vent 102 to keep the heat dissipation vent 102 closed.

[0039] The support component 3 is made of hot melt adhesive. If a fire breaks out inside the electrical cabinet 1, the temperature inside the cabinet 1 will rise relatively, and the support component 3 will gradually melt in the high-temperature environment. The melted support component 3 will be insufficient to support the counterweight 4. Under the influence of gravity, the counterweight 4 falls downward. At the same time, since the two ends of the first connecting rod 401 are hinged to the counterweight 4 and the movable plate 2 respectively, the counterweight 4 pulls the lower end of the first connecting rod 401 when it falls. The movable plate 2 is pulled by the upper end of the first connecting rod 401 and slides towards the heat dissipation vent 102 until the movable plate 2 is attached to the heat dissipation vent 102, making the heat dissipation vent 102 closed. Thus, by the movable plate 2 being attached to the heat dissipation vent 102, it is difficult for outside air to enter the electrical cabinet 1 through the heat dissipation vent 102, thereby reducing the air circulation inside the electrical cabinet 1 and reducing the amount of oxygen inside the electrical cabinet 1, thus effectively suppressing the fire source.

[0040] In this embodiment, the top surface of the electrical cabinet 1 is provided with a container 5 for storing dry powder. The bottom surface of the container 5 and the top surface of the electrical cabinet 1 are connected through a connection port. The container 5 and the interior of the electrical cabinet 1 are connected through two connection ports.

[0041] A baffle 6 is slidably fitted inside the connection port of the electrical cabinet 1. A second connecting rod 402 is provided between the baffle 6 and the first connecting rod 401. The two ends of the second connecting rod 402 are respectively hinged to the bottom surface of the baffle 6 and the first connecting rod 401.

[0042] The electrical cabinet 1 has a receiving groove on the side wall of the connection port for accommodating the baffle 6. As the counterweight 4 falls, it pulls the first connecting rod 401, causing the lower end of the second connecting rod 402 to move synchronously with the first connecting rod 401. This causes the upper end of the second connecting rod 402 to move the baffle 6 toward the receiving groove. As the baffle 6 moves, it gradually exposes the connection port, allowing the dry powder in the receiving box 5 to enter the electrical cabinet 1 through the connection port. On the one hand, the dry powder falls directly onto the fire source to extinguish it; on the other hand, the dry powder floats inside the electrical cabinet 1, effectively reducing the contact between air and the fire source.

[0043] In this embodiment, a support membrane 601 is provided inside the connection port of the container 5, and the support membrane 601 covers the connection port;

[0044] The container 5 is connected to a pressure pump 7, and the output end of the pressure pump 7 is connected to the inside of the container 5.

[0045] After filling the dry powder into the container 5, close the lid of the container 5 and start the pressurization pump 7 to pressurize the air in the container 5 to a certain level. When the baffle 6 moves into the container slot, the dry powder will be temporarily supported by the support membrane 601, so that it will not be directly output into the electrical cabinet 1 through the connection port. The support membrane 601 will gradually melt due to the high temperature and fire source in the electrical cabinet 1. At this time, because the container 5 has been pressurized in advance, the dry powder will be sprayed into the electrical cabinet 1 through the connection port for fire extinguishing.

[0046] In this embodiment, the electrical cabinet 1 is also provided with a tapping component, which is located between the electrical components and the connection port. The tapping component is rotatably connected to the electrical cabinet 1, and the rotation path of the tapping component is perpendicular to the through direction of the connection port.

[0047] By installing the beater assembly, the sprayed dry powder can be beaten, allowing the dry powder to extinguish fires over a wider area and float better within the electrical cabinet 1.

[0048] In this embodiment, the striking assembly includes multiple rods 8 and multiple collars 801 arranged along the length of the rods 8. One end of the rod 8 is rotatably connected to the electrical cabinet 1, and the collars 801 are rotatably sleeved on the rods 8. Each of the opposite ends of the collars 801 is provided with a flip plate 802.

[0049] Because the tilting plate 802 is mounted on the rod body 8 via a bearing, when the tilting plate 802 is impacted by the sprayed dry powder, the tilting plate 802 will rotate to strike the rod body 8, causing the dry powder to extinguish the fire over a wide area.

[0050] In this embodiment, the movable plate 2 includes a plate body 201 and a frame body 202. The frame body 202 is slidably engaged with the heat dissipation vent 102, and the plate body 201 is fixed on the side of the frame body 202 away from the heat dissipation vent 102.

[0051] The frame 202 has guide grooves 2021 on opposite sides, the guide grooves 2021 extend along the slotting direction of the heat dissipation groove, and guide blocks 1021 are provided on opposite sides of the heat dissipation groove within the guide grooves 2021.

[0052] When the first link 401 is pulled by the counterweight 4, the first link 401 will pull the plate 201 to move toward the heat dissipation port 102. During this process, the guide block 1021 is inserted into the guide groove 2021 and can move along the length of the guide groove 2021, so that the frame 202 and the plate 201 can only slide along the length of the guide groove 2021. The length of the guide groove 2021 can limit the sliding distance of the frame 202 and the plate 201, so that they will not fall off the heat dissipation port 102.

[0053] In this embodiment, a sealing groove 103 surrounding the heat dissipation port 102 is provided on the side wall of the electrical cabinet 1, and a sealing ring 2011 is provided on the side of the plate 201 near the heat dissipation port 102. The sealing groove 103 is located at the end of the sliding path of the plate 201.

[0054] When the first connecting rod 401 pulls the plate 201 to the limit distance of the guide groove 2021, the sealing ring 2011 on the plate 201 is interference-fitted with the sealing groove 103 on the electrical cabinet 1. At this time, the sealing ring 2011 is embedded in the sealing groove 103 under compression. Thus, through the cooperation of the plate 201, the sealing ring 2011 and the sealing groove 103, the heat dissipation port 102 is sealed, reducing the amount of air flowing into the electrical cabinet 1 through the heat dissipation port 102.

[0055] In this embodiment, a through hole 2022 is provided on the side wall of the frame 202.

[0056] When the heat dissipation vent 102 is open, the first connecting rod 401 has not yet pulled the plate 201 toward the heat dissipation vent 102. At this time, both the frame 202 and the plate 201 are located outside the electrical cabinet 1. External oxygen can enter the heat dissipation vent 102 through the through hole 2022 and then enter the electrical cabinet 1 to achieve heat exchange of the gas.

[0057] In this embodiment, the electrical cabinet 1 is also provided with a base 9 located below the counterweight 4. The top surface of the base 9 is provided with a groove recessed along the thickness direction of the base 9, and the support 3 is placed in the groove.

[0058] Before use, place the support 3 in the groove of the base 9, and then place the counterweight 4 on the support 3. If a fire breaks out in the electrical cabinet 1, the support 3 will melt due to high temperature, and the liquid produced by the melting will fall into the groove, which can be collected and reused by reprocessing the melted liquid.

[0059] In this embodiment, a heat-conducting rod 901 is provided between the base 9 and the fixing plate 101, and the two ends of the heat-conducting rod 901 are detachably connected to the fixing plate 101 and the base 9, respectively.

[0060] The heat-conducting rod 901 is connected to the fixed plate 101 and the base 9 at both ends, so that when the electrical components on the fixed plate 101 are in the event of a fire, the temperature of the fixed plate 101 will rise due to the influence of the fire source. At this time, the heat-conducting rod 901 will transfer the heat of the fixed plate 101 to the base 9, and the base 9 will further melt the support 3.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
