Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Such as Figures 1 to 9As shown in the figure, the present invention provides a temperature monitoring and alarm device for computer network equipment, including a first box body 1 and a second box body 2. An installation cover 3 is fixedly installed inside the first box body 1 and the second box body 2. A support column 4 is fixedly connected to the central position inside the installation cover 3. A multi-stage response mechanism for triggering different response operations according to different temperatures inside the box body is installed inside the installation cover 3. The multi-stage response mechanism includes a first response component, a second response component, and a third response component. The first response component, the second response component, and the third response component are respectively installed on the outer wall of the support column 4 from bottom to top. A heat conduction component for transmitting the temperature inside the box body to the first response component and the second response component in real time is installed at the bottom inside the installation cover 3. A heat dissipation component is installed on the inner wall of the installation cover 3. The heat dissipation component includes two embedded plates 81 and four groups of heat dissipation plates 8. While the multi-stage response mechanism is working, the opening and closing degrees of the embedded plates 81 and the heat dissipation plates 8 are adjusted through the first response component according to the temperature inside the box body. The first box body 1 and the second box body 2 of the above device are designed to be detachable, so as to facilitate the operator to maintain and replace the internal structure of the box body and improve the convenience of subsequent operations. The first response component, the second response component, and the third response component are coaxially installed on the outer wall of the support column 4 from bottom to top with the support column 4 as the axis. Each response component corresponds to a different temperature threshold, so as to trigger different operations to achieve corresponding effects. Through the pure mechanical structure design, the stability of the multi-stage response mechanism operation can be ensured, and at the same time, the problems that traditional electronic modules are vulnerable to electromagnetic interference and high temperature effects can be avoided.

[0031] As Figure 3 , Figure 5 and Figure 6As shown in the figure, the thermal conduction component includes a plurality of heat conducting fins 41. The plurality of heat conducting fins 41 are fixedly connected to the bottom of the outer wall of the support column 4 at equal intervals with the center of the support column 4 as the axis. The bottom of the heat conducting fin 41 is in contact with the inner bottom wall of the first box body 1 or the second box body 2. A aluminum layer 43 is fixedly connected to the middle and lower part of the outer wall of the support column 4, and an invar alloy layer 42 is fixedly connected to the outer wall of the aluminum layer 43; The first response component includes two first fixing blocks 5. The two first fixing blocks 5 are respectively fixedly connected to both sides of the top wall of the aluminum layer 43. A first connecting rod 51 is fixedly connected to the outer wall of the first fixing block 5. The first connecting rod 51 is designed with a bend. Mounting frames 52 are fixedly connected to the two sides of the outer wall of the support column 4 corresponding to the first fixing blocks 5. A guide plate 54 is rotatably connected to the inner wall of the mounting frame 52 through a rotating rod 53. The end of the first connecting rod 51 is fixedly connected to the outer wall of the guide plate 54. The end of the guide plate 54 is fixedly connected to the middle of the outer wall of the embedded plate 81; The second response component includes a brass layer 6. The brass layer 6 is fixedly connected to the middle of the outer wall of the support column 4. A stainless steel layer 61 is fixedly connected to the outer wall of the brass layer 6. Second fixing blocks 62 are fixedly connected to both sides of the top wall of the brass layer 6. The installation positions of the two second fixing blocks 62 and the two first fixing blocks 5 are staggered from each other in the vertical projection. A second connecting rod 63 is fixedly connected to the outer wall of the second fixing block 62. The end of the second connecting rod 63 is fixedly connected to an impact block 64. Impact plates 65 are fixedly connected to both sides of the inner wall of the installation cover 3. The impact block 64 can collide with the impact plate 65 through the movement of the second connecting rod 63.

[0032] Adopting the above scheme: The temperature inside the box is quickly transferred by a plurality of heat conducting fins 41 and high thermal conductivity silicone grease 13. At the same time, a significant difference is formed between the high expansion of the aluminum layer 43 and the low expansion of the invar alloy layer 42, which can generate sufficient deformation at about 30°C. The first response component can convert and amplify the deformation on the surface of the aluminum layer 43 through the first connecting rod 51 with a bend design and a lever structure, so as to realize the cooperation with the heat dissipation component; The principle of the second response component is the same as that of the first response component. The thermal conduction material is replaced by a combination of a brass layer 6 + a stainless steel layer 61, and the size of the composite structure disk of the brass layer 6 and the stainless steel layer 61 is slightly smaller than that of the invar alloy layer 42 and the aluminum layer 43. When the temperature inside the installation cover 3 reaches about 50°C, the brass layer 6 gradually deforms, thereby driving the second connecting rod 63 to control the impact block 64 to contact the impact plate 65, and sending a reminder alarm to the user through the impact beeping sound. In the initial state, the second connecting rod 63 does not contact the impact plate 65. At the same time, the deformation of the aluminum layer 43 continues, driving the embedded plate 81 to continue moving to the maximum heat dissipation area.

[0033] As Figures 2 to 8As shown in the figure, the third response component includes two connecting plates 7, which are respectively fixedly connected to the rear end of the inner top wall of the installation cover 3. The adjacent sides of the outer walls of the two connecting plates 7 are rotatably connected with support rods 71. The bottom of the support rod 71 is fixedly connected with a fixing plate 72. The outer wall of the fixing plate 72 is fixedly installed with a plug 73. Springs 74 and alloy wires 75 are respectively fixedly installed on both sides of the support rod 71. The support rod 71 is connected to the outer wall of the support column 4 and the inner wall of the installation cover 3 through the spring 74 and the alloy wire 75 respectively. A socket 76 is opened at the top of the rear end of the inner wall of the installation cover 3. The socket 76 is connected in series with the computer circuit and is adapted to the plug 73; two embedded plates 81 are respectively rotatably connected to both sides of the inner wall of the installation cover 3. The outer wall of the installation cover 3 is divided into six equal parts, and each equal part area corresponds to a heat dissipation plate 8. Four groups of heat dissipation plates 8 are distributed in pairs on both sides of the installation cover 3. Sliding grooves 83 are opened at both the upper and lower ends of the inner wall of the installation cover 3. Sliders 82 are fixedly connected to both the upper and lower ends of the outer wall of the embedded plate 81. The embedded plate 81 is slidably connected to the inner wall of the sliding groove 83 through the slider 82 to realize the sliding connection with the installation cover 3.

[0034] With the above scheme: the design of the spring 74 and the alloy wire 75 plays a balancing effect on the support rod 71, thus ensuring the stable connection between the plug 73 and the socket 76. When the temperature inside the box continues to rise and exceeds 70°, the alloy wire 75 starts to melt, the balance of the support rod 71 is broken, and the plug 73 is separated from the socket 76 through the elastic force of the spring 74, realizing the power-off of the circuit. Moreover, the socket 76 and the computer circuit are connected in series, so as to ensure that the circuit is connected only when both interfaces are connected; the embedded plate 81 is slidably connected to the inner wall of the installation cover 3 through the slider 82. In the initial state, the two embedded plates 81 are respectively placed at the positions of the heat dissipation plates 8 provided on the installation cover 3. The embedded plate 81 is driven through the first response component, and the moving direction is towards the position where no heat dissipation plate 8 is provided, so as to gradually increase the heat dissipation area of the installation cover 3 until it is maximized, realizing the heat dissipation effect.

[0035] As Figures 1 to 9 As shown in the figure, limiting strips 12 are fixedly connected to both sides of the inner wall of the sliding groove 83. The size of the limiting strip 12 is adapted to an equal part area after the outer wall of the installation cover 3 is divided into six equal parts; mounting plates 9 are fixedly connected to both sides of the outer walls of the first box body 1 and the second box body 2. Positioning holes 10 are opened at both ends of the outer wall of the mounting plate 9. The two mounting plates 9 are connected through a pin 11 passing through the positioning hole 10; the inside of the support column 4 is filled with a high thermal conductivity silicone grease 13 material; the outer walls of the aluminum layer 43 and the brass layer 6 on the side close to the support column 4 are both designed as spiral corrugated structures.

[0036] Adopting the above solution: By installing the limiting strip 12 inside the chute 83, the moving position of the embedded panel 81 can be limited, thereby preventing the embedded panel 81 from covering the heat dissipation plate 8; The first box body 1 and the second box body 2 are quickly installed through the mounting plate 9, improving the convenience of using the device; The sides of the aluminum layer 43 and the brass layer 6 in contact with the support column 4 are both designed with spiral corrugated structures, thereby improving the effect of the deformation of the metal disc and ensuring that both achieve spiral deformation.

[0037] The working principle and usage process of the present invention:

[0038] The first box body 1 and the second box body 2 are attached through the mounting plates 9 on both sides of the top, and the quick disassembly and assembly of the two box bodies are realized through the insertion of the latch 11 into the positioning hole 10. When the temperature inside the box body begins to rise, the temperature contacts the first response component and the second response component through air and the heat conducting sheet 41. Since both ends of the heat conducting sheet 41 are respectively in contact with the box body and the support column 4, and the inside of the support column 4 is filled with a high thermal conductivity silicone grease 13 material, the rapidity and stability of heat transfer are ensured. In the first response component, the response structure is supported by the invar alloy layer 42 and the aluminum layer 43. There is a significant difference between the high expansion of aluminum and the low expansion of the invar alloy, which can generate sufficient deformation at a low temperature of 30 °C. The deformation on the surface of the aluminum layer 43 controls the movement of the first fixing blocks 5 on both sides, thereby driving the first connecting rod 51 to initially amplify the small movement of the first fixing block 5. The mounting frame 52 is fixedly connected to the support column 4, and the lever effect is achieved through the connection of the rotating rod 53 and the guide plate 54. The end of the first connecting rod 51 is connected to the outer wall of the guide plate 54, and the rotating rod 53 divides the guide plate 54 unevenly. The mechanical kinetic energy of the guide plate 54 is realized through the push of the first connecting rod 51, thereby driving the movement of the embedded plate 81 and realizing the adjustment of the heat dissipation area of the heat dissipation component. The outer wall of the mounting cover 3 is designed with six equal parts, and the heat dissipation plates 8 are designed in two adjacent equal parts areas. When the temperature of the box body is normal, the first connecting rod 51 drives the embedded plate 81 to be in the equal part area of the preset heat dissipation plate 8. When the temperature continues to rise, the deformation of the aluminum layer 43 also continues, simultaneously driving the embedded plate 81 to continue to rotate and increase the heat dissipation area. The design of the limit strip 12 can limit the movement position of the embedded plate 81 to prevent the embedded plate 81 from continuously rotating and affecting the heat dissipation area at high temperatures. When the temperature reaches about 50 °C, the spiral deformation on the surface of the brass layer 6 is realized through the expansion difference between the brass layer 6 and the stainless steel layer 61, thereby driving the second connecting rod 63 to move through the second fixing block 62, ensuring that the end of the second connecting rod 63 can contact the impact piece 65 through the impact block 64 to realize the impact buzzer reminder. The impact piece 65 is fixed on the inner wall of the mounting cover 3 at a position where the embedded plate 81 cannot rotate, thereby avoiding mutual interference between the first response component and the second response component. When the temperature continues to rise above 75 °C, the alloy wire 75 begins to melt, the plug 73 loses the pulling force, and it disengages from the socket 76 through the elastic effect of the spring 74 to realize the automatic power-off effect. When the temperature drops, the metal disc returns to its initial state, thereby pulling the embedded plate 81 and the impact block 64 to their initial positions. Through the multi-stage response mechanism, it is ensured that this design can achieve different usage effects at different temperature thresholds, improving the practicability of the device and the stability of the structure operation.
