Description

Technical Field

[0001] This application relates to the field of ventilation devices, and more particularly to a fire-resistant ventilation device. Background Technology

[0002] In numerous industrial and civilian applications, various types of equipment—such as electrical equipment cabinets, industrial furnaces, and energy storage containers—require ventilation systems to achieve critical functions such as heat dissipation and air circulation. However, current ventilation systems have significant shortcomings in fire resistance.

[0003] like Figure 1 and Figure 2 The traditional ventilation device is typically constructed as follows: a base 10 is installed on the target device, and a ventilation channel 11 is opened on the base 10 to connect the inside and outside of the target device; a baffle 12 is hinged to the side of the base 10 facing the outside of the target device to cover the ventilation channel 11; and a control mechanism 13 is provided inside the base 10 to be responsible for the opening and closing operation of the baffle 12.

[0004] However, if a fire breaks out inside the target device, or if the ambient temperature rises sharply and exceeds the temperature threshold that the control mechanism can withstand, the control mechanism will fail. This can cause the opened baffles to fail to close properly, or the baffles to become loose, thus failing to effectively isolate the flames and allowing them to spread outwards. This hazard could cause the fire to spread to surrounding equipment, ultimately damaging it. Utility Model Content

[0005] In order to improve the fire resistance of ventilation devices and their flame isolation effect, this application provides a fire-resistant ventilation device.

[0006] The fire-resistant ventilation device provided in this application adopts the following technical solution:

[0007] A fireproof ventilation device includes: a base, a ventilation channel disposed on the base; a baffle movably disposed on the base and used to block the ventilation channel; and a control mechanism for controlling the opening and closing of the baffle.

[0008] It also includes: a protective cover, installed on the side of the base facing the target device; a vent, disposed on the protective cover, and the vent is opposite to the ventilation channel; a partition, movably disposed on the base and tending to block the vent; and a limiting component, disposed on the base and used to limit the partition from blocking the vent, wherein the limiting component can release the limiting effect on the partition when the temperature reaches a preset value.

[0009] Optionally, the limiting component includes a rod disposed on the base, the rod being used to restrict the movement of the partition, the rod melting when the temperature reaches a preset value, and releasing the limiting effect on the partition.

[0010] Optionally, the protective cover has an opening corresponding to the insertion rod position, the opening being used to expose the insertion rod.

[0011] Optionally, the partition is slidably disposed on the base, and the partition can move downward under the action of gravity and block the vent. The limiting component is used to restrict the downward movement of the partition.

[0012] Optionally, a limiting plate is fixedly connected to the base, the limiting plate and the inner wall of the protective cover form a guide groove, the partition is slidably disposed in the guide groove, and the limiting component is disposed on the limiting plate.

[0013] Optionally, the limiting plate is provided with a socket for inserting the plug rod, and the limiting plate is provided with a limiting plate corresponding to the position of the socket, and the limiting plate is used to control the size of the plug rod inserted into the socket.

[0014] Optionally, a first heat insulation plate is provided on the inner wall of the protective cover, and the first heat insulation plate is used to cover the control mechanism inside the base.

[0015] Optionally, a second heat insulation plate is provided on the side of the partition facing the base, and the second heat insulation plate is covered with a shell.

[0016] Optionally, the base is movably provided with a cover on the side facing away from the target device to cover the baffle and the ventilation channel, and the cover can be pushed open when the baffle is opened under the action of the control mechanism.

[0017] Optionally, the baffle has a cavity inside, and a third heat insulation plate is provided inside the cavity.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By setting up partitions and limiting components, when the internal temperature of the target device reaches a preset value, the limiting components automatically release the partition. Under the action of gravity, the partition quickly blocks the ventilation opening, effectively preventing the spread of flames and high-temperature gases, which helps to improve the fire safety of the ventilation device.

[0020] 2. The sliding partition and guide groove structure ensures the stability and accuracy of the partition movement; the insertion rod can detect the temperature rise in time. When the temperature reaches the melting point of the insertion rod, it releases the limiting effect on the partition, allowing the partition to move down in the guide groove to achieve the sealing effect of the ventilation opening.

[0021] 3. The installation of the first, second, and third heat insulation plates further enhances the heat insulation performance of the device and reduces the impact of heat transfer on the components around the target device. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.

[0034] This application discloses a fire-resistant ventilation device. For example... Figure 1 and Figure 2 The fireproof ventilation device includes a base 10 installed on the outer wall of the target device. The base 10 is provided with a ventilation channel 11 for connecting the inside and outside of the target device to enable air circulation. A baffle 12 for blocking the ventilation channel 11 is movably installed on the base 10. The baffle 12 can be hinged or slidably installed on the base 10. In this embodiment, the baffle 12 is hinged to the base 10. A control mechanism 13 is provided inside the base 10 to control the opening and closing of the baffle 12.

[0035] Specifically, the control mechanism 13 includes a rotating shaft fixedly connected to the baffle 12, and the baffle 12 is hinged to the base 10 via the rotating shaft. The rotating shaft extends into the base 10, and a crank is fixedly connected to the rotating shaft. An electric push rod for controlling the rotation of the crank is provided inside the base 10.

[0036] like Figure 3 A protective cover 20 is provided on the base 10, and the protective cover 20 is installed on the side of the base 10 facing the target device; a vent 21 is provided on the protective cover 20, and the vent 21 is arranged opposite to the ventilation channel 11; a partition 22 is movably provided on the base 10, and the partition 22 tends to block the vent 21; a limiting component 28 is provided on the base 10, and the limiting component 28 is used to limit the partition 22 from blocking the vent 21. When the temperature reaches a preset value, the limiting component 28 can release the limiting effect on the partition 22.

[0037] The target device in this embodiment is an energy storage container. An installation port is provided on the side wall of the energy storage container. The base 10 is snapped into the installation port and fixed to the outer wall of the energy storage container with screws, thus fixing the position of the base 10 on the energy storage container. A protective cover 20 is provided on the side of the base 10 facing the inside of the energy storage container. The protective cover 20 can be directly installed on the base 10 or installed on the energy storage container. The protective cover 20 provides heat insulation, reducing the impact of excessively high internal temperatures in the energy storage container and ensuring the normal operation of the control structure 13 or other electrical components inside the base 10. The limiting component 28 is used to limit the partition 22 from blocking the ventilation opening 21, allowing normal ventilation when the partition 12 is open. When a fire occurs inside the energy storage container, the internal temperature of the container rises rapidly. When the temperature reaches the preset value of the limiting component 28, the limiting component 28 releases its limiting effect on the partition 22. The partition 22 can block the ventilation opening 21, reducing the problem of failure of the control structure 13 or other electrical components in the base 10 at high temperatures, allowing the baffle 12 to close normally, thereby effectively isolating the flame and reducing the spread of the fire.

[0038] like Figure 4The partition 22 can tend to close the vent 21 under its own weight, or it can tend to close the vent 21 under the action of an elastic element. In this embodiment, the partition 22 is vertically slidably disposed on the base 10, and tends to move downward and block the vent 21 by relying solely on its own weight. The limiting component 28 on the base 10 restricts the partition 22 from moving downward under the action of gravity.

[0039] Figure 5 and Figure 6 Specifically, a limiting plate 23 is fixedly connected to the base 10. The limiting plate 23 is symmetrically arranged about the ventilation opening 21. The limiting plate 23 and the inner wall of the protective cover 20 form a guide groove 27. The guide groove 27 is U-shaped, and the openings of the two guide grooves 27 are opposite to each other. A partition 22 is installed between the two guide grooves 27 and can slide within the two guide grooves 27 to vertically guide the partition 22 and improve the stability of the vertical movement of the partition 22. A limiting component 28 is installed on the limiting plate 23 and is used to restrict the downward sliding of the partition 22 within the two guide grooves 27.

[0040] Under its own gravity, the partition 22 tends to move downwards. Without the operator needing to drive the partition 22 to move through other drive components, when the limiting component 28 releases its limiting effect on the partition 22, the partition 22 can move downwards stably along the guide groove 27 under the action of gravity and block the ventilation opening 21. During this process, the downward movement of the partition 22 is not easily affected by the external environment, making the downward movement of the partition 22 stable.

[0041] Figure 6 , Figure 7 as well as Figure 8 The limiting component 28 includes a rod 29 disposed on the base 10. The rod 29 is used to limit the downward sliding of the partition 22. The rod 29 melts when the temperature reaches its melting point and releases the limiting effect on the partition 22.

[0042] The insertion rod 29 is made of a thermoplastic material, such as tin-lead alloy or aluminum-silicon alloy. When the temperature reaches the melting point of the insertion rod 29, the insertion rod 29 melts and releases the limiting effect on the partition 22, allowing the partition 22 to move down smoothly and block the ventilation opening 21, achieving a heat insulation effect. This reduces the possibility of excessively high internal temperature of the energy storage container, which could lead to failure of the drive mechanism inside the base 10. It also helps to improve the sealing effect of the baffle 12 on the ventilation channel 11, achieving the purpose of flame isolation.

[0043] The limiting plate 23 is provided with a socket 24 for inserting the insertion rod 29. A limiting seat 25 is provided on the limiting plate 23 corresponding to the socket 24, and the limiting seat 25 is used to control the insertion size of the insertion rod 29 into the socket 24. The limiting seat 25 is U-shaped, with its opening facing the socket 24, and is located on the side of the limiting plate 23 away from the protective cover 20. The protective cover 20 has an opening 26 corresponding to the insertion rod 29, which is opposite to the socket 24 and is used to expose the insertion rod 29. The operator inserts the insertion rod 29 through the opening 26 and into the through hole until the insertion rod 29 enters the limiting seat 25 and abuts against the inner wall of the limiting seat 25, thereby limiting the insertion size of the insertion rod 29.

[0044] The limiting plate 23 is provided with insertion holes 24 for inserting rods 29. A limiting seat 25 is provided on the limiting plate 23 corresponding to the insertion hole 24. The limiting seat 25 acts as a limiting structure to control the insertion size of the rod 29 into the insertion hole 24. By controlling the insertion size of the rods 29, the insertion size of each rod 29 into the through hole is kept consistent, ensuring that the partition 22 can be stably held in a position that does not obstruct the vent 21 under normal conditions. Simultaneously, when the temperature reaches a preset value, the rods 29 can reliably melt and release the limiting effect on the partition 22. This design improves the adjustment accuracy and reliability of the limiting component 28.

[0045] An opening 26 is provided on the protective cover 20 to expose the insertion rod 29, so that the internal temperature of the energy storage container can directly affect the insertion rod 29, and the insertion rod 29 can melt quickly when the temperature inside the energy storage container reaches a preset value.

[0046] Figure 5 and Figure 7 A first heat insulation plate 30 is provided on the inner wall of the protective cover 20, and the first heat insulation plate 30 is set inside the protective cover 20 corresponding to the control mechanism 13 inside the base 10, and covers the area where the control mechanism 13 is located. The first heat insulation plate 30 can effectively reduce the transmission of high temperature inside the energy storage container to the base 10, reduce the risk of damage to the control mechanism 13 due to high temperature, and help improve the service life of the ventilation device, as well as the fire resistance and stability of the entire ventilation device.

[0047] Figure 8 and Figure 9A second heat insulation plate 31 is installed on the side of the partition 22 facing the base 10, and a housing 32 is installed over the second heat insulation plate 31. The function of the second heat insulation plate 31 is to further prevent the high temperature inside the target device from being transferred to the outside of the ventilation device through the partition 22, ventilation channel 11, and baffle 20, thereby enhancing the heat insulation effect of the partition 22. The housing 32 protects the second heat insulation plate 31, preventing it from being damaged or worn during use and transportation, ensuring the stability of its heat insulation performance, and improving the fire resistance reliability of the entire ventilation device.

[0048] A cover 33 for covering the baffle 12 and the ventilation channel 11 is movably provided on the side of the base 10 facing the target device. When the baffle 12 is opened under the action of the control mechanism 13, the cover 33 can be pushed open. A cavity is provided inside the cover 33, and a third heat insulation plate 34 is provided inside the cavity.

[0049] Figure 9 and Figure 10 A cover 33 is hinged to the side of the base 10 facing outwards from the energy storage container. This cover is used to shield the baffle 12 and the ventilation channel 11, preventing the flame inside the energy storage container from spreading outwards and protecting the components around the energy storage container from damage. At the same time, when the baffle 12 is opened under the action of the control mechanism 13, it can push open the cover 33 without affecting the normal ventilation function of the ventilation device, thus achieving a combination of ventilation and protection.

[0050] like Figure 4 and Figure 9 The baffle 33 has a cavity inside, and a third heat insulation plate 34 is installed inside the cavity. The third heat insulation plate 34 can effectively reduce the impact of the high temperature inside the energy storage container on surrounding equipment, further improve the fire resistance of the ventilation device, and enhance the safety of the energy storage container. The baffle 33 protects the third heat insulation plate 34, reducing the possibility of damage or wear to the third heat insulation plate 34 during long-term use.

[0051] 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.
