Abstract
Description
Technical Field
[0001] This application relates to the field of ventilation equipment, and in particular to a high-temperature self-opening ventilation window. Background Technology
[0002] In enclosed installations such as computer rooms, warehouses, power distribution cabinets, and energy storage containers, heat is generated during equipment startup or storage, causing the internal temperature to rise. To effectively maintain air circulation within these enclosed spaces and promptly reduce temperature, the installation of ventilation windows is crucial. Ventilation windows not only provide a channel for air exchange between the enclosed space and the outside environment but also, to a certain extent, ensure environmental stability and safety within the space.
[0003] Ventilation windows can be opened and closed in various ways. They can be operated manually to meet the needs of simple scenarios or emergency situations, or they can be opened and closed precisely with the help of advanced electronic control equipment to achieve automated and intelligent management.
[0004] However, traditional ventilation windows mostly rely on electronic control devices to remotely control the opening and closing of the window sashes. While this method improves the convenience of operation to some extent, it also poses some potential risks. If the temperature inside the enclosed space exceeds normal levels, and the electronic control device used to remotely open the window sash malfunctions due to power failure, short circuit, or operator negligence or delayed response, the ventilation window will fail to open properly. This situation will directly prevent effective air exchange between the enclosed space and the outside, making it difficult to reduce the concentration of flammable gases inside and to dissipate heat properly. Over time, the risk of explosion or thermal runaway within the enclosed space will increase significantly, posing a serious threat to the safety of people and property. Utility Model Content
[0005] In order to alleviate the problem of ventilation windows failing to open and close properly due to damage to the electronic control device, and to ensure normal heat dissipation and air exchange in enclosed spaces, this application provides a high-temperature self-opening ventilation window.
[0006] The high-temperature self-opening ventilation window provided in this application adopts the following technical solution:
[0007] A high-temperature self-opening ventilation window includes a frame for mounting on a target device housing. The frame has an opening for connecting the inside and outside of the target device. A cover plate is hinged to the frame, and the cover plate flips to control the opening and closing of the opening. A control assembly for controlling the flipping of the cover plate is provided on the frame. The control assembly includes a slide block slidably mounted on the frame. A drive unit for controlling the movement of the slide block is provided on the frame. A connecting rod is movably mounted between the slide block and the cover plate. The movement of the slide block pushes the cover plate to flip via the connecting rod. The connecting rod is a telescopic rod, and an elastic unit is provided on the telescopic rod. The elastic unit pushes the telescopic rod to remain in a retracted state. A temperature-sensitive limiter is connected to the telescopic rod to limit its extension.
[0008] By adopting the above technical solution, the frame provides the installation foundation and connects the inside and outside of the target device. The cover plate controls the opening and closing of the opening through a flip-up mechanism, achieving the ventilation function. The sliding block in the control assembly moves under the action of the drive unit, pushing the cover plate to flip via a telescopic rod. This design allows the ventilation window to be remotely controlled and its opening and closing status adjusted, increasing the flexibility and automation of ventilation. The elastic unit and temperature-sensitive limiter on the telescopic rod keep the telescopic rod retracted under normal conditions, preventing the cover plate from opening automatically. When the temperature rises to the activation threshold of the temperature-sensitive limiter, the limiter releases its restriction on the telescopic rod, and the elastic unit controls the extension of the telescopic rod to push the cover plate open, effectively addressing ventilation needs in high-temperature environments and ensuring the stability of the internal environment of the target device. This design, through the cooperation of the elastic unit and the temperature-sensitive limiter, enables the cover plate to automatically open under high-temperature conditions when the drive unit is affected by factors such as high temperature, short circuit, or power failure, thus improving the safety of the device.
[0009] Optionally, the telescopic rod includes a sleeve and an inner rod that slides through the sleeve. The elastic unit and the temperature-sensitive limiter are both disposed between the sleeve and the inner rod. The elastic unit is used to push the inner rod out of the sleeve, and the temperature-sensitive limiter is used to restrict the inner rod from extending out of the sleeve. The slide and the cover plate are both provided with hinge seats. The sleeve is hinged to one of the hinge seats, and the inner rod is hinged to the other hinge seat.
[0010] By adopting the above technical solution, the telescopic rod includes a sleeve and an inner rod that slides and extends within the sleeve. The elastic unit and the temperature-sensitive limiter are both set between the sleeve and the inner rod. The spring is used to push the inner rod out of the sleeve, and the temperature-sensitive limiter is used to limit the inner rod from extending out of the sleeve. When the temperature rises to the activation threshold of the temperature-sensitive limiter, the temperature-sensitive limiter releases the limiting effect between the inner rod and the sleeve, and the spring pushes the inner rod out of the sleeve. In the case of a failure of the drive unit, the cover plate can be automatically opened under high temperature.
[0011] Optionally, the elastic unit includes a spring sleeved on the inner rod, the spring pushing the inner rod so that the inner rod tends to extend out of the sleeve.
[0012] By adopting the above technical solution, a spring fitted on the inner rod serves as an elastic unit, pushing the inner rod towards extending out of the sleeve. This design gives the telescopic rod an automatic extension tendency. Under normal circumstances, the temperature-sensitive limiter restricts the extension of the inner rod, and the spring is in a compressed state. When the temperature-sensitive limiter fails, the spring can quickly release energy, pushing the inner rod out of the sleeve, realizing the extension of the telescopic rod, thereby quickly pushing the cover plate to flip and open the ventilation window. In the case of drive unit failure, it ensures that the ventilation window can respond and open in a timely manner at high temperatures, improving the response speed and reliability of the ventilation window.
[0013] Optionally, the temperature-sensitive limiter includes a hot-melt rod connected between the inner rod and the sleeve to limit the inner rod from extending out of the sleeve.
[0014] By employing the above technical solution, a thermoplastic rod is used as a temperature-sensitive limiter connected between the inner rod and the sleeve. The melting characteristics of the thermoplastic rod at a specific temperature are used to limit and release the extension of the inner rod from the sleeve. When the temperature rises to the melting point of the thermoplastic rod, it melts, and the inner rod extends from the sleeve under the action of a spring, thus automatically opening the cover. This temperature-sensitive limiting method is simple, direct, and low-cost. It can accurately control the opening of the ventilation window according to the set temperature, making it suitable for situations where temperature control requirements are not particularly precise but timely ventilation is needed. It effectively solves the problem of insufficient ventilation inside the target device in high-temperature environments.
[0015] Optionally, the sleeve is provided with a first limiting ring, and the inner rod is provided with a second limiting ring. The first limiting ring can be aligned with the second limiting ring and is used for the insertion of the hot melt rod, so as to restrict the inner rod from extending out of the sleeve.
[0016] By adopting the above technical solution, a first limiting ring and a second limiting ring are respectively set on the sleeve and the inner rod, and the hot-melt rod is inserted between the first limiting ring and the second limiting ring, further clarifying the specific structure of the hot-melt rod restricting the extension of the inner rod. This structure makes the installation of the hot-melt rod more stable, can more accurately restrict the position of the inner rod, and ensure the sealing and stability of the ventilation window under normal temperature. At the same time, when the hot-melt rod melts, the inner rod can smoothly extend out of the sleeve, realizing the opening function of the ventilation window and improving the working reliability of the ventilation window in high-temperature environments.
[0017] Optionally, the temperature-sensing limiter includes a limit pin, a first limit groove on the sleeve, and a second limit groove on the inner rod. The first and second limit grooves are alignable and are used for insertion of the limit pin. The limit pin is slidably disposed on the sleeve. The limit pin has a first inclined surface, and a second inclined surface is provided in the second limit groove to abut against the first inclined surface. The sleeve has a temperature-sensing limiting unit for limiting the limit pin from extending out of the second limit groove.
[0018] By adopting the above technical solution, a temperature-sensitive limiter is constructed using a limiting pin, a first limiting groove, a second limiting groove, and a temperature-sensitive limiting unit. The limiting pin, inserted into the first and second limiting grooves, restricts the inner rod from extending out of the sleeve. The temperature-sensitive limiting unit restricts the movement of the limiting pin. When the temperature rises to a specific value, the temperature-sensitive limiting unit releases its limiting effect on the inner rod. Under the action of the elastic unit, the limiting pin pushes the first inclined surface, causing it to disengage from the second limiting groove, and the inner rod gradually extends out of the sleeve, thus realizing the opening function of the ventilation window.
[0019] Optionally, the temperature-sensing limiting unit includes a bracket disposed on the sleeve, a limiting pin slidably disposed within the bracket, and a temperature-sensing glass bulb supported between the bracket and the limiting pin. The temperature-sensing glass bulb pushes the limiting pin so that the first inclined surface abuts against the second inclined surface, thereby limiting the inner rod from extending out of the sleeve.
[0020] By adopting the above technical solution, the temperature-sensing limiting unit includes a bracket, a limiting pin, and a temperature-sensing bulb. The temperature-sensing bulb pushes the limiting pin so that the first inclined surface extends into the second limiting groove and abuts against the second inclined surface within the second limiting groove, thereby restricting the inner rod from extending out of the sleeve. When the temperature rises to the sensing temperature of the temperature-sensing bulb, the bulb ruptures, and the limiting pin disengages from the second limiting groove under the action of a spring or other force, allowing the inner rod to extend out of the sleeve. This temperature-sensing limiting unit utilizes the characteristics of the temperature-sensing bulb to stably control the opening temperature of the ventilation window.
[0021] Optionally, the drive unit includes an electric push rod fixedly connected to the frame, and the movable part of the electric push rod is fixedly connected to the slide.
[0022] By adopting the above technical solution, the drive unit uses an electric actuator, and the moving part of the electric actuator is fixedly connected to the slide. The electric actuator has the advantages of high control precision and fast response speed, and can accurately control the moving distance and speed of the slide, thereby precisely controlling the flipping angle of the cover and the opening and closing degree of the ventilation window.
[0023] In summary, this application includes at least one of the following beneficial technical effects: when it is necessary to dissipate heat from a closed target device, the cover can be flipped by the drive unit to achieve the effect of heat dissipation and air exchange; when the drive unit is damaged or difficult to open in time, the cover can be automatically opened under high temperature by the cooperation of the elastic unit and the temperature sensing limiter, which helps to improve the safety of the device.

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail. Example 1
[0034] This application discloses a high-temperature self-opening ventilation window. For example... Figure 1and Figure 2 The high-temperature self-opening ventilation window includes a frame 11, which is used to install on the closed housing of the target device. The frame 11 is provided with an opening 12 for connecting the inside and outside of the housing of the target device. A cover plate 13 is hinged to the frame 11, and the opening and closing of the opening 12 can be controlled by flipping the cover plate 13.
[0035] like Figure 2 and Figure 3 A control component 2 is provided on the frame 11. The control component 2 includes a slide block 21 slidably mounted on the frame 11. A drive unit 3 for controlling the movement of the slide block 21 is provided on the frame 11. A connecting rod is movably connected between the slide block 21 and the cover plate 13. The drive unit 3 controls the movement of the slide block 21 and drives the cover plate 13 to flip through the connecting rod. The drive unit 3 can be a motor, cylinder, etc., for controlling the movement of the slide block 21. In this embodiment, the drive unit 3 includes an electric push rod 31 mounted on the frame 11. The body of the electric push rod 31 is hinged to the inner wall of the opening 12 of the frame 11, and the moving part of the electric push rod 31 is hinged to the slide block 21. The operator can control the moving part of the electric push rod 31 to move, thereby causing the slide block 21 to slide on the frame 11, thereby driving the cover plate 13 to flip through the connecting rod, achieving the opening and closing effect of the opening 12.
[0036] The connecting rod is a telescopic rod 22, which includes a sleeve 23 and an inner rod 24. The inner rod 24 slides through the sleeve 23. Both the slide block 21 and the cover plate 13 are provided with hinge seats 25. The sleeve 23 is hinged to one of the hinge seats 25, and the inner rod 24 is hinged to the other hinge seat 25.
[0037] An elastic unit 4 is provided on the telescopic rod 22. The elastic unit 4 can be a tension spring, a spring sheet, or an elastic band, etc. In this embodiment, the elastic unit 4 includes a spring 41 sleeved on the inner rod 24. The spring 41 pushes the inner rod 24, causing the inner rod 24 to tend to extend out of the sleeve 23. A temperature-sensitive limiter 5 is connected to the telescopic rod 22. In this embodiment, the temperature-sensitive limiter 5 includes a thermoplastic rod 51, which is connected between the inner rod 24 and the sleeve 23 to limit the inner rod 24 from extending out of the sleeve 23.
[0038] like Figure 2 and Figure 4 The sleeve 23 is provided with a first limiting ring 52, and the inner rod 24 is provided with a second limiting ring 53. By controlling the movement of the inner rod 24 within the sleeve 23, the first limiting ring 52 and the second limiting ring 53 can be aligned. In this embodiment, the through-holes of the first limiting ring 52 and the second limiting ring 53 are axially perpendicular to the extension and retraction direction of the inner rod 24 within the sleeve 23. The hot-melt rod 51 is inserted into the first limiting ring 52 and the second limiting ring 53 to restrict the inner rod 24 from extending out of the sleeve 23.
[0039] When the internal temperature of the target device is normal, the hot melt rod 51 remains solid, restricting the inner rod 24 from extending out of the sleeve 23, and the spring 41 is in a compressed state. When the internal temperature of the target device rises to the melting point of the hot melt rod 51, the hot melt rod 51 melts, the inner rod 24 extends out of the sleeve 23 under the action of the spring 41, the telescopic rod 22 extends, pushing the cover plate 13 to flip, opening the opening 12, and increasing the ventilation.
[0040] The target device is equipped with a controller and various detectors, with the detectors electrically connected to the controller, which in turn is electrically connected to the electric push rod 31. When the detector detects that the temperature, combustible gas concentration, smoke concentration, or other factors inside the target device reach a preset threshold, the detector sends an electrical signal to the controller. Upon receiving the signal, the controller controls the electric push rod 31 to extend, thereby controlling the slide 21 to move. This allows the cover plate 13 to flip open via a connecting rod, opening the opening 12 for ventilation and heat dissipation. In the event of circuit failure and the electric push rod 31 failing to start normally, if the internal temperature of the target device rises to the melting point of the hot melt rod 51, the hot melt rod 51 melts. The inner rod 24 extends out of the sleeve 23 under the action of the spring 41, and the telescopic rod 22 extends, pushing the cover plate 13 to automatically flip and opening the opening 12. Example 2
[0041] like Figure 5 , Figure 6 as well as Figure 7 This embodiment 2 is basically the same as embodiment 1, except for the structure of the temperature-sensing limiter 5. The temperature-sensing limiter 5 includes a limit pin 62, a first limit groove 6 is formed on the outer wall of the sleeve 23, and a second limit groove 61 is formed on the outer wall of the inner rod 24. The inner rod 24 slides within the sleeve 23, which can align the first limit groove 6 and the second limit groove 61, and is used for the insertion of the limit pin 62. When the limit pin 62 is inserted into the first limit groove 6 and the second limit groove 61, it can restrict the relative movement of the inner rod 24 and the sleeve 23, thereby restricting the extension of the inner rod 24, so that the spring 41 remains in a compressed state.
[0042] like Figure 7 and Figure 8 A limiting pin 62 is slidably disposed on the sleeve 23, and the limiting pin 62 can move to insert into or disengage from the sleeve 23. The limiting pin 62 is provided with a first inclined surface 63 for abutting against the wall of the second limiting groove 61, and the wall of the second limiting groove 61 is provided with a second inclined surface 67. Under the elastic force of the spring 41, the inner rod 24 can cause the second inclined surface 67 to push against the first inclined surface 63, applying a force to the limiting pin 62 to disengage from the second limiting groove 61. The sleeve 23 is provided with a temperature-sensitive limiting unit 65, which is used to prevent the limiting pin 62 from disengaging from the second limiting groove 61.
[0043] The temperature sensing limiting unit 65 includes a bracket 64 fixedly connected to the outer wall of the sleeve 23, a limiting pin 62 slidably disposed in the bracket 64, and a temperature sensing glass bulb 66 disposed between the bracket 64 and the limiting pin 62. The temperature sensing glass bulb 66 pushes the limiting pin 62 so that the limiting pin 62 remains inserted into the second limiting groove 61. In this state, the first inclined surface 63 abuts against the second inclined surface 67 in the second limiting groove 61 so as to limit the inner rod 24 from extending out of the sleeve 23.
[0044] When the internal temperature of the target device is normal, the temperature-sensing bulb 66 is intact, restricting the movement of the limiting pin 62. The limiting pin 62 is inserted into the first limiting groove 6 and the second limiting groove 61, restricting the inner rod 24 from extending out of the sleeve 23. When the internal temperature of the target device rises to the sensing temperature of the temperature-sensing bulb 66, the temperature-sensing bulb 66 breaks. Under the pushing action of the second inclined surface 67, the limiting pin 62 disengages from the second limiting groove 61. Under the elastic force of the spring 41, the inner rod 24 extends out of the sleeve 23, the telescopic rod 22 extends, pushing the cover plate 13 to flip, causing the opening 12 to open.
[0045] 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.
