Description

Technical Field

[0001] The present invention relates to the field of network devices, and particularly to an outdoor cabinet with high heat insulation performance. Background Art

[0002] An outdoor cabinet refers to a cabinet that is directly under the influence of natural climate, mostly made of metal materials, and does not allow unauthorized operators to enter and operate. It is a device that provides an outdoor physical working environment and a security system for wireless communication sites or wired network site workstations.

[0003] The use of outdoor cabinets faces the test of large day-night temperature differences in outdoor weather. The existing method is generally to adhere a heat insulation layer to the cabinet. Adhering the heat insulation layer can indeed effectively reduce the temperature exchange between the inside and outside of the cabinet. However, in the case of overheating such as a short circuit inside the cabinet, the heat insulation layer becomes an obstacle to heat dissipation, making the cabinet more likely to catch fire and reducing safety. Summary of the Invention

[0004] The purpose of the present invention is to provide an outdoor cabinet with high heat insulation performance to solve the above problems.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: An outdoor cabinet with high heat insulation performance includes a cabinet body. The cabinet body includes two side plates, ventilation holes are opened on the side plates, two wiring grooves are symmetrically fixed inside the cabinet, and a heat insulation component is provided in front of each wiring groove. The heat insulation component includes a pair of first slide rails and second slide rails symmetrically fixed on the cabinet up and down. Two first sliders are slidably installed in the first slide rails, a first metal plate is fixed between the four first sliders. Second sliders are slidably installed in the second slide rails, a third slide rail is fixed on each pair of second sliders, two third sliders are slidably installed in the third slide rail, and a second metal plate is fixed between the four third sliders. The second metal plate and the first metal plate can be used as reinforcement members of the cabinet body;

[0007] A first layer of thermal insulation cotton is fixed on the first metal plate. A number of ventilation grooves are formed in the first layer of thermal insulation cotton. Through holes are formed in the first metal plate at the positions of the ventilation grooves. The through holes are communicated with the ventilation holes. A number of metal strips are fixed on the second metal plate. The metal strips define communication grooves for ventilation. A second layer of thermal insulation cotton is fixed on the metal strips. Each second layer of thermal insulation cotton is inserted into the corresponding ventilation groove to form an integral thermal insulation layer. Under normal working conditions, the second layer of thermal insulation cotton blocks the through holes to ensure the thermal insulation effect. Electric telescopic components are symmetrically fixed on the top inside the cabinet. The electric telescopic components control telescopic rods. The telescopic rods are fixed to one of the third slide rails.

[0008] A temperature detector is fixed inside the cabinet to detect the temperature of the cabinet. A controller is also integrated inside the cabinet.

[0009] Preferably, a fan group is installed on the top of the cabinet.

[0010] Preferably, fans are installed at the positions of the communication grooves. The fans are fixed on two adjacent metal strips through support frames. A key switch is fixed on the top inside the cabinet. The key switch is used to control the on / off of each fan. The third slide rail is aligned with the key switch.

[0011] Preferably, each fan is in a parallel circuit. The key switch is located on the main circuit. And the key switch is normally open.

[0012] Preferably, the second metal plate is detachable from the third slider. A first fixing head is fixed on each third slider. A hole is formed in the first fixing head. Holes are also formed at the corresponding positions on the second metal plate.

[0013] Preferably, the first slider is also detachable from the first metal plate. A second fixing head is fixed on each first slider. A hole is formed in the second fixing head. Holes are also formed at the corresponding positions on the first metal plate.

[0014] Preferably, after the third slider is inserted into the third slide rail and the first slider is inserted into the first slide rail, they are fixed by gluing.

[0015] Preferably, both the first layer of thermal insulation cotton and the second layer of thermal insulation cotton are trapezoidal.

[0016] In summary, the present invention has the following beneficial effects:

[0017] 1. There are two wiring grooves symmetrically fixed inside the cabinet of the present application for wiring. A thermal insulation component is provided on the front side of each wiring groove. The thermal insulation component includes a pair of first sliding rails and second sliding rails symmetrically fixed on the upper and lower sides of the cabinet. Two first sliders are slidably installed in the first sliding rails. A first metal plate is fixed between the four first sliders. Second sliders are slidably installed in the second sliding rails. A third sliding rail is fixed on each pair of second sliders. Two third sliders are slidably installed in the third sliding rail. A second metal plate is fixed between the four third sliders. The second metal plate and the first metal plate can be used as reinforcement members of the cabinet, which are convenient to install and detachable.

[0018] 2. A thermal insulation layer is arranged between the second metal plate and the first metal plate, greatly enhancing the thermal insulation performance of the cabinet, facilitating outdoor use, and the thermal insulation layer can be detached together with the second metal plate and the first metal plate, facilitating the installation of the thermal insulation layer without gluing the thermal insulation layer to the side plate, greatly reducing the workload.

[0019] 3. A first heat-insulating cotton is fixed on the first metal plate. A number of ventilation grooves are opened on the first heat-insulating cotton. Through holes are opened on the first metal plate at the positions of the ventilation grooves. The through holes are communicated with ventilation holes. A number of metal strips are fixed on the second metal plate. The metal strips partition out communication grooves for ventilation. Second heat-insulating cotton is fixed on the metal strips. Each second heat-insulating cotton is inserted into the corresponding ventilation groove to form a whole layer of thermal insulation layer. And under the normal working state, the second heat-insulating cotton blocks the through holes to ensure the thermal insulation effect. Electric telescopic components are symmetrically fixed on the top inside the cabinet. The electric telescopic components control telescopic rods. The telescopic rods are fixed to one of the third sliding rails. A temperature detector is fixed inside the cabinet to detect the temperature of the cabinet. A controller is also integrated inside the cabinet. When the temperature detector detects that the temperature inside the cabinet is too high, the controller controls the electric telescopic components to start and retracts the telescopic rods. The telescopic rods drive the third sliding rail together with the second metal plate away from the first metal plate. At this time, the second heat-insulating cotton no longer blocks the through holes, and a gap will be generated between the first heat-insulating cotton and the second heat-insulating cotton. The outside air will blow into the cabinet from the through holes on one side and the gap between the first heat-insulating cotton and the second heat-insulating cotton for heat dissipation, and blow out from the through holes on the other side and the gap between the first heat-insulating cotton and the second heat-insulating cotton, greatly enhancing the ventilation and heat dissipation function in case of emergency and ensuring the safety of the cabinet.

[0020] 4. Fans are installed at the positions of the communication grooves. The fans are fixed on two adjacent metal strips through support frames. A key switch is fixed on the top inside the cabinet. The key switch is used to control the on / off of each fan. The third sliding rail is aligned with the key switch. After the telescopic rod drives the third sliding rail to move, the third sliding rail will press the key switch to control the start of each fan. After the fans start, the air flow inside the cabinet is greatly strengthened, accelerating the cooling of the cabinet. Description of the Drawings

Detailed implementation manners

[0031] Combined with the attached Figures 1-8The described outdoor cabinet with high heat preservation performance includes a cabinet body, and the cabinet body includes two side plates 11. Ventilation holes 10 are opened on the side plates 11, and waterproof treatment needs to be done at the ventilation holes 10 (by adding a waterproof cover, etc., not shown). Two wiring grooves 35 are symmetrically fixed in the cabinet body for wiring. A heat preservation component is provided on the front side of each wiring groove 35. The heat preservation component includes a pair of first slide rails 21 and second slide rails 24 symmetrically fixed on the upper and lower parts of the cabinet. Two first sliders 22 are slidably installed in the first slide rails 21. A first metal plate 29 is fixed among the four first sliders 22. Second sliders 25 are slidably installed in the second slide rails 24. A third slide rail 28 is fixed on each pair of second sliders 25. Two third sliders 26 are slidably installed in the third slide rail 28. A second metal plate 12 is fixed among the four third sliders 26. The second metal plate 12 and the first metal plate 29 can be used as reinforcement parts of the cabinet body, which are convenient to install and detachable;

[0032] A heat preservation layer is arranged between the second metal plate 12 and the first metal plate 29, which greatly enhances the heat preservation performance of the cabinet body, is convenient for outdoor use, and the heat preservation layer can be detached together with the second metal plate 12 and the first metal plate 29, which facilitates the installation of the heat preservation layer without sticking the heat preservation layer to the side plate 11, greatly reducing the workload;

[0033] However, the adoption of the heat preservation layer will affect the heat dissipation of the cabinet body. Therefore, the heat preservation layer is optimized. Specifically, a first heat preservation cotton 20 is fixed on the first metal plate 29. A plurality of ventilation grooves 33 are opened on the first heat preservation cotton 20. Through holes 34 are opened on the first metal plate 29 at the positions of the ventilation grooves 33. The through holes 34 communicate with the ventilation holes 10. A plurality of metal strips 15 are fixed on the second metal plate 12. The metal strips 15 define communication grooves 36 for ventilation. Second heat preservation cotton 19 is fixed on the metal strips 15. Each second heat preservation cotton 19 is inserted into the corresponding ventilation groove 33 to form an integral heat preservation layer. And in the normal working state, the second heat preservation cotton 19 blocks the through holes 34 to ensure the heat preservation effect. Electric telescopic components 31 are symmetrically fixed on the top of the cabinet body. The electric telescopic components 31 control telescopic rods 32, and the telescopic rods 32 are fixed to one of the third slide rails 28;

[0034] A temperature detector 16 is fixed inside the cabinet to detect the temperature of the cabinet. A controller is also integrated inside the cabinet. When the temperature detector 16 detects that the temperature inside the cabinet is too high, the controller controls the electric telescopic assembly 31 to start, retract the telescopic rod 32, and the telescopic rod 32 drives the third slide rail 28 and the second metal plate 12 away from the first metal plate 29. At this time, the second heat insulation cotton 19 no longer blocks the through hole 34, and a gap will be generated between the first heat insulation cotton 20 and the second heat insulation cotton 19. The wind from the outside will blow into the cabinet for heat dissipation through each through hole 34 on one side and the gap between the first heat insulation cotton 20 and the second heat insulation cotton 19, and blow out through each through hole 34 on the other side and the gap between the first heat insulation cotton 20 and the second heat insulation cotton 19, greatly enhancing the ventilation and heat dissipation function in case of emergency and ensuring the safety of the cabinet.

[0035] Of course, in the normal working state, a fan group 18 is installed on the top of the cabinet of the present application for heat dissipation. When the temperature is too high, the fan group 18 also works. This part is common technology in the art and will not be elaborated in the present application.

[0036] To further enhance the air circulation effect inside the cabinet when the temperature inside the cabinet is too high, fans 14 are installed at the positions of the communication grooves 36. The fans 14 are fixed on two adjacent metal strips 15 through a support frame 13. A key switch 30 is fixed on the top inside the cabinet. The key switch 30 is used to control the on / off of each fan 14. The third slide rail 28 is aligned with the key switch 30. After the telescopic rod 32 drives the third slide rail 28 to move, the third slide rail 28 will press the key switch 30 to control each fan 14 to start. After the fans 14 start, the air flow inside the cabinet is greatly enhanced, accelerating the cooling of the cabinet.

[0037] It should be noted that each fan 14 is in a parallel circuit, the key switch 30 is located on the main circuit, and the key switch 30 is normally open. When it is pressed, the parallel circuit is always powered off, and when it is being pressed, the parallel circuit is powered on.

[0038] To reduce the production difficulty, the second metal plate 12 and the third slider 26 are detachable. A first fixing head 27 is fixed on each third slider 26. The first fixing head 27 has an opening, and corresponding positions on the second metal plate 12 also have openings. After the holes on the first slide rail 21 are aligned with the holes on the first fixing head 27, the second metal plate 12 and the third slider 26 can be fixed by bolts and nuts.

[0039] Similarly, the first slider 22 is also detachable from the first metal plate 29. A second fixed head 23 is fixed on each of the first sliders 22. The second fixed head 23 has an opening, and the corresponding position on the first metal plate 29 also has an opening. After the holes on the first metal plate 29 are aligned with the holes on the second fixed head 23, the second fixed head 23 and the first metal plate 29 can be fixed by bolts and nuts.

[0040] It should be particularly noted that after the third slider 26 is inserted into the third slide rail 28 and the first slider 22 is inserted into the first slide rail 21, they are fixed by glue adhesion. Of course, they can also be fixed by other means, such as fixing through openings with bolts and nuts, etc.

[0041] Both the first heat insulation cotton 20 and the second heat insulation cotton 19 are trapezoidal. While being mutually adapted, the inclined surfaces on both sides can also play a certain guiding role for the wind.

[0042] Usage method:

[0043] During normal operation, the heat insulation layer is used to reduce the heat exchange between the inside of the cabinet and the outside world, effectively insulate the inside of the cabinet, so that each electrical component inside the cabinet can be in a good working state.

[0044] In case of a short circuit or other situations, when the temperature detector 16 detects that the temperature inside the cabinet is too high, it feeds back to the controller, and the controller controls the electric telescopic assembly 31 to start, retract the telescopic rod 32. The telescopic rod 32 drives the third slide rail 28 together with the second metal plate 12 away from the first metal plate 29. At this time, the second heat insulation cotton 19 no longer blocks the through hole 34, and a gap will be generated between the first heat insulation cotton 20 and the second heat insulation cotton 19. The wind from the outside will blow into the cabinet for heat dissipation from the through holes 34 on one side and the gap between the first heat insulation cotton 20 and the second heat insulation cotton 19, and blow out from the through holes 34 on the other side and the gap between the first heat insulation cotton 20 and the second heat insulation cotton 19, greatly enhancing the ventilation and heat dissipation function in case of emergency and ensuring the safety of the cabinet.

[0045] After the telescopic rod 32 drives the third slide rail 28 to move, the third slide rail 28 will press the button switch 30 to control the start of each of the fans 14. After the fans 14 start, the air flow inside the cabinet is greatly strengthened, accelerating the cooling of the cabinet.

[0046] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and their purpose is to enable those skilled in this field to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
