Those skilled in the art will understand the specific meanings of the above terms in the present invention according to specific circumstances.
[0025] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.
[0026] See also Figure 1-7, the present invention provides a technical solution: a hardware cabinet of an edge computing network system, comprising a first cabinet 1, a second cabinet 2 being slidably connected to the first cabinet 1, a hardware installation position 9 being arranged in the second cabinet 2, the hardware installation position 9 being used to install the hardware equipment of the edge computing network system, the part of the first cabinet 1 connected to the second cabinet 2 and the second cabinet 2 being made of high-temperature resistant heat-insulating material, a second through-hole 4 being provided on the second cabinet 2, a first through-hole 3 corresponding to the second through-hole 4 being provided on the first cabinet 1, a temperature regulating unit 5 for regulating the relative position of the first cabinet 1 and the second cabinet 2 according to temperature changes is installed between the first cabinet 1 and the second cabinet 2, a heat-conducting member for transferring heat between the temperature regulating unit 5 and the outside of the first cabinet 1 is provided on the first cabinet 1, so that when the hardware is at normal working temperature, the hardware installation position 9 is communicated with the outside of the first cabinet 1 through the first through-hole 3 and the second through-hole 4, in case of fire, the first cabinet 1 and the second cabinet 2 cooperate to form a closed cavity structure surrounding the hardware installation position 9 formed by high-temperature resistant heat-insulating material, so that the normal working of the hardware can be prevented during use. When the outside temperature is set to between 20-40°C, the first through hole 3 and the second through hole 4 are opposite to each other, and the vent aperture formed by the first through hole 3 and the second through hole 4 of the entire cabinet is the largest, which is convenient for heat dissipation of the equipment in the cabinet. When the outside temperature is higher than 40°C, as the temperature rises, the outside temperature is transferred to the temperature adjustment unit 5 through the heat conductor, and the temperature adjustment unit 5 causes the second cabinet body 2 to slide relative to the first cabinet body 1, thereby gradually reducing the aperture of the vent. When the outside temperature reaches 90°C, the vent is completely closed. The temperature continues to rise, and the vent remains in a closed state. The closed cavity surrounded by high-temperature resistant insulation material can protect the hardware at the hardware installation position 9 from damage by fire, effectively preventing flames, high temperatures and smoke from entering the cabinet, protecting the hardware equipment, so that the hardware cabinet has good heat dissipation and fire prevention performance. The outside temperature for normal operation of the hardware can also be set to a suitable temperature range such as between 20-45°C and between 15-40°C. Within this temperature range, the first through hole 3 and the second through hole 4 are opposite to each other.
[0027] In one embodiment, the temperature adjustment unit 5 includes a control rod 5.1 made of a thermal expansion material. The material of the control rod 5.1 can be made of a suitable material such as polytetrafluoroethylene, aluminum, etc., and each control rod 5.1 is installed with an amplification mechanism 5.2 for amplifying the length change of the control rod 5.1. The two ends of each amplification mechanism 5.2 are connected to the first cabinet 1 and the second cabinet 2.
[0028] In one embodiment, each amplification mechanism 5.2 includes a first connecting rod 5.2.1 and a second connecting rod 5.2.2. One end of the first connecting rod 5.2.1 is rotatably connected to the first cabinet 1, the other end of the first connecting rod 5.2.1 is rotatably connected to one end of the second connecting rod 5.2.2, and the other end of the second connecting rod 5.2.2 is rotatably connected to the second cabinet 2. The first connecting rod 5.2.1 and the second connecting rod 5.2.2 are rotatably connected to the control rod 5.1, and the control rod 5.1 is close to the rotation of the first connecting rod 5.2.1 and the second connecting rod 5.2.2. At the dynamic connection, the thermal expansion coefficients of the first connecting rod 5.2.1, the second connecting rod 5.2.2 and the control rod 5.1 are different, among which the thermal expansion coefficients of the first connecting rod 5.2.1 and the second connecting rod 5.2.2 are smaller than the thermal expansion coefficient of the control rod 5.1. When the length of the control rod 5.1 is adjusted by temperature changes, the first connecting rod 5.2.1 and the second connecting rod 5.2.2 cooperate to amplify the changed length of the control rod 5.1 by the lever principle, thereby driving the second cabinet 2 to slide within the first cabinet 1.
[0029] In one embodiment, a first mounting rod 5.2.3 is welded to a side of the first connecting rod 5.2.1 away from the second connecting rod 5.2.2, and a second mounting rod 5.2.4 is welded to a side of the second connecting rod 5.2.2 away from the first connecting rod 5.2.1. The first mounting rod 5.2.3 and the second mounting rod 5.2.4 are rotatably connected to the control rod 5.1 at two ends away from each other. The thermal expansion coefficients of the first mounting rod 5.2.3, the second mounting rod 5.2.4 and the control rod 5.1 are different. The thermal expansion coefficient of the first connecting rod 5.2.1, the second connecting rod 5.2.2, the first mounting rod 5.2.3 and the second mounting rod 5.2.4 are parallel to each other at the rotating connection points. Since the thermal expansion coefficients of the first mounting rod 5.2.3 and the second mounting rod 5.2.4 are different from those of the control rod 5.1, the angle change between the first connecting rod 5.2.1 and the second connecting rod 5.2.2 caused by the length change of the control rod 5.1 is amplified, thereby amplifying the length change of the control rod 5.1 for the second time.
[0030] In one embodiment, the first connecting rod 5.2.1, the second connecting rod 5.2.2, the first mounting rod 5.2.3, and the second mounting rod 5.2.4 are made of a heat-conducting material. The first connecting rod 5.2.1, the second connecting rod 5.2.2, the first mounting rod 5.2.3, and the second mounting rod 5.2.4 are made of a suitable material such as iron, steel, gray cast iron, etc. The first connecting rod 5.2.1 is in contact with the heat-conducting member, and the external temperature transfers heat to the control rod 5.1 through the heat-conducting member, the first connecting rod 5.2.1, the second connecting rod 5.2.2, the first mounting rod 5.2.3, and the second mounting rod 5.2.4, thereby facilitating the adjustment of the length of the control rod 5.1.
[0031] In one embodiment, the first cabinet 1 includes a first shell 1.1 and a second shell 1.2. The first shell 1.1 is made of a high-temperature resistant heat-insulating material. The first shell 1.1 is slidably connected to the second cabinet 2. The second shell 1.2 is made of a suitable heat-conducting material such as iron or steel. A temperature adjustment unit 5 is installed between the second shell 1.2 and the second cabinet 2. The second shell 1.2 forms a heat-conducting member. The first shell 1.1 and the second shell 1.2 are fixed with bolts.
[0032] In one embodiment, reference Figure 4 The first shell 1.1 and the second cabinet 2 include an inner layer 2.1 and an outer layer 2.2 made of high-temperature resistant material, and an inner core 2.3 made of high-temperature resistant heat-insulating material is sandwiched between the inner layer 2.1 and the outer layer 2.2, wherein the inner layer 2.1 and the outer layer 2.2 are made of suitable materials such as low-carbon steel and iron. Furthermore, suitable high-temperature resistant heat-insulating coatings such as ZS-1 steel structure fireproof, heat-insulating and scalding-proof materials can be applied to the surfaces away from each other on the inner layer 2.1 of the second cabinet 2 and the outer layer 2.2 of the first shell 1.1, and the inner core 2.3 is a suitable heat-insulating material such as a vacuum insulation panel and aerogel felt, so that the first shell 1.1 and the second cabinet 2 can cooperate to form a closed cavity surrounded by high-temperature resistant heat-insulating material and surrounding the hardware installation position 9.
[0033] In one embodiment, the first cabinet body 1 is installed with a first limit member 6 for limiting the movement of the second cabinet body 2 at the front side in the direction of movement of the second cabinet body 2 when the temperature rises, and when the first limit member 6 contacts the second cabinet body 2, the first through holes 3 and the second through holes 4 do not contact each other, wherein the first limit member 6 is a blocking bar, the first shell 1.1 includes an annular enclosure, one side of the annular enclosure is bolted to the second shell 1.2, the other side of the annular enclosure is the cabinet opening of the first cabinet body 1, and the other side of the annular enclosure is screwed to the cabinet door, and each blocking bar and the annular enclosure are an integral structure; the first cabinet body 1 is slidably connected to the second limit member 7, and when the second cabinet body 2 slides relative to the first cabinet body 1, each second limit member 7 slides in contact with the second cabinet body 2, and when the second cabinet body 2 contacts the first limit member 6, the first cabinet body 1 is fixedly connected to the second cabinet body 2 through the cooperation of each second limit member 7 and the first limit member 6.
[0034] In one embodiment, the sliding direction of the second cabinet body 2 relative to the first cabinet body 1 is parallel to the horizontal plane, and the first cabinet body 1 opens a sliding hole 8 above the second cabinet body 2, and the lower part of each second limiting member 7 is slidably connected to the sliding hole 8, and the radial dimension of the upper end of each second limiting member 7 is larger than the aperture size of the sliding hole 8, wherein the second limiting member 7 is an "L"-shaped rod. When the second cabinet body 2 contacts the first limiting member 6, the second limiting member 7 slides downward relative to the sliding hole 8 under the action of gravity, thereby cooperating with the first limiting member 6 to clamp the second cabinet body 2, so that the relative position of the first cabinet body 1 and the second cabinet body 2 is fixed.
[0035] Among them, when the external temperature rises to a certain temperature, such as 100℃, 120℃, etc., the second cabinet 2 moves to contact with the first limiter 6. At this time, the relative positions of the first cabinet 1 and the second cabinet 2 are fixed. As the temperature rises, the length of the control rod 5.1 continues to increase, thereby causing the length of the temperature adjustment unit 5 to continue to increase. At this time, the relative positions of the first cabinet 1 and the second cabinet 2 can be maintained by the deformation of the second shell 1.2 at the first connecting rod 5.2.1. The bolts at the connection between the first shell 1.1 and the second shell 1.2 can also be used to maintain the first cabinet 1 and the second cabinet 2 fixed. A cabinet 1 and a second cabinet 2 are fixed relative to each other, such as the first shell 1.1 and the second shell 1.2 are fixedly connected by bolts. The bolts are made of a suitable material such as polycarbonate. The thermal deformation temperature of polycarbonate is 130-140°C. When the first cabinet 1 and the second cabinet 2 are fixed relative to each other, as the temperature rises, the second shell 1.2 is slightly deformed, and the bolts are thermally deformed. As the temperature continues to rise, the threads are damaged, causing the first shell 1.1 and the second shell 1.2 to separate. The first cabinet 1 and the second cabinet 2 remain fixed relative to each other and do not Affected by the length of the control rod 5.1; when the hardware is at normal operating temperature, the first through hole 3 and the second through hole 4 are opposite, and the vent hole diameter is the largest, which is convenient for heat dissipation of the equipment in the cabinet. When a fire occurs, as the temperature rises, the external temperature is transferred to the temperature adjustment unit 5 through the heat conduction member. The temperature adjustment unit 5 makes the second cabinet 2 slide relative to the first cabinet 1, so that the diameter of the vent hole gradually decreases. When the external temperature reaches a certain value, such as 90°C, the vent hole is completely closed. If the temperature continues to rise, the vent hole remains closed. In this state, the closed cavity composed of high-temperature resistant heat-insulating material formed by the cooperation of the first shell 1.1 and the second cabinet 2 makes the hardware installation position 9 in a high-temperature resistant heat-insulating closed state, effectively preventing flames, high temperatures and smoke from entering the interior of the cabinet, and protecting the hardware equipment from damage by fire. In this way, when the hardware is at normal working temperature, the hardware installation position 9 is connected to the outside of the first cabinet 1 through the first through hole 3 and the second through hole 4. When a fire occurs, the first cabinet 1 and the second cabinet 2 cooperate to form a structure of a closed cavity surrounded by high-temperature resistant heat-insulating material surrounding the hardware installation position 9.
[0036] The present invention has been described in detail above by way of specific embodiments and examples, but these do not constitute limitations of the present invention. Without departing from the principles of the present invention, those skilled in the art may make many variations and improvements, which should also be considered within the scope of protection of the present invention.
