Description

Technical Field

[0001] This utility model belongs to the field of heat dissipation, and specifically relates to a fireproof electrical cabinet for electrical applications. Background Technology

[0002] An electrical cabinet is a metal device housing switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment. It is used in power systems for the protection, control, and distribution of electrical energy, and is widely applied in various industries to ensure the safety of the system during normal operation and in case of faults. The main function of an electrical cabinet is to connect or disconnect circuits manually or automatically during normal operation. In case of faults or abnormal operation, it uses protective electrical appliances to cut off the circuit or trigger alarms. It can also adjust certain electrical parameters and provide alerts or signals for deviations from normal operating conditions.

[0003] In existing technologies, electrical cabinets need to protect the electrical components inside around the clock. However, during long-term operation of electrical components, they are prone to generating high heat. Traditional heat dissipation methods only use cooling fans to dissipate heat inside the cabinet, which is not very efficient and generates a lot of noise. At the same time, it is impossible to effectively deal with abnormal temperature rise inside the electrical cabinet, which leads to frequent fire accidents.

[0004] Therefore, it is necessary to provide a fireproof electrical cabinet for electrical applications to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fireproof electrical cabinet for electrical applications, comprising: a cabinet body, a control console, a temperature control mechanism, and electrical component modules;

[0006] The control console is mounted on the cabinet and is used to adjust the parameters of the electrical device module;

[0007] The electrical component module is located inside the cabinet and is electrically connected to the control console; the temperature control module is located on the cabinet and is used to adjust the heat dissipation status of the cabinet in real time.

[0008] Specifically, the temperature control module includes: two heat dissipation components, a fan, and an adjustment mechanism;

[0009] Two heat dissipation components are symmetrically arranged on both sides of the cabinet; the guide fan is fixedly installed inside the cabinet; the adjustment mechanism is fixed on the inner wall of the cabinet and connected to the heat dissipation components, and is used to adjust the opening and closing degree of the heat dissipation components according to the internal temperature of the cabinet.

[0010] As a further improvement of this utility model, the heat dissipation component includes:

[0011] The mounting frame is fixed to the cabinet and has multiple air guide vanes rotatably mounted inside it. Drive components are provided at both ends of the air guide vanes. The drive components are connected to the adjustment mechanism through slide grooves, which are formed on the mounting frame.

[0012] As a further improvement of this utility model, the adjustment mechanism includes: a temperature control component, an adjustment component, and a push plate;

[0013] The temperature control component is fixed to the inner wall of the cabinet and slidably connected to one end of the adjustment component; the other end of the adjustment component is fixedly connected to the push plate, and the push plate is connected to the drive component.

[0014] As a further improvement of this utility model, the temperature control component includes:

[0015] The housing is fixed to the cabinet by a fixing seat, and one end of the piston rod is slidably disposed inside the housing. The other end of the piston rod is connected to the adjustment assembly.

[0016] The nozzle is fixed to the housing.

[0017] As a further improvement of this utility model, the sealed space formed by the housing and the piston rod is filled with liquid perfluorohexanone.

[0018] As a further improvement of this utility model, the adjusting component includes: a slide cylinder, a compression spring, and a guide rod;

[0019] One end of the slide cylinder is slidably sleeved on the piston rod, and the other end is fixedly provided with one end of the guide rod, the other end of the guide rod being connected to the push plate;

[0020] One end of the compression spring is fixedly mounted on the slide cylinder, and the other end is connected to the piston rod.

[0021] As a further improvement of this utility model, the driving component includes:

[0023] The rack is slidably disposed within the mounting frame and meshes with the gear; the rack is also fixedly connected to the push plate;

[0024] A return spring is disposed between the rack and the mounting frame.

[0025] As a further improvement of this utility model, the adjustment mechanism is provided on both the upper and lower sides of the heat dissipation component for monitoring the internal temperature of the cabinet in different zones.

[0026] As a further improvement of this utility model, a power interface is also provided on the cabinet.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] 1. Changes in the temperature inside the cabinet cause continuous changes in the vaporization effect of liquid perfluorohexanone, which in turn causes the drive components to adjust the opening and closing angle of the air guide vanes according to the changes in the cabinet temperature, thereby controlling the air circulation efficiency and improving the heat dissipation effect.

[0029] 2. By increasing the opening angle of the air guide vanes, the resonance phenomenon between the air and the air guide vanes will also be reduced, thereby reducing the decibel of heat dissipation noise.

[0030] 3. When the temperature inside the cabinet exceeds the safety threshold, perfluorohexanone will be sprayed through the nozzle onto the electrical component module and the entire cabinet. The air guide vanes will rotate synchronously to close the cabinet, preventing the perfluorohexanone from leaking out and isolating the air, further preventing fire and improving safety.

[0031] 4. When the electrical components module is in a stopped state, the opening and closing degree of the air guide vanes is zero, that is, the cabinet is kept in a closed state under the action of the air guide vanes, thereby preventing dust from entering. Attached Figure Description

[0042] See Figures 1 to 9 As shown, a fireproof electrical cabinet for electrical use is characterized by comprising: a cabinet body 1, a control console 2, a temperature control mechanism, and an electrical component module 6;

[0043] The control console 2 is mounted on the cabinet 1 and is used to adjust the parameters of the electrical device module 6;

[0044] The electrical device module 6 is located inside the cabinet 1 and is electrically connected to the control console 2; the temperature control module is located on the cabinet 1 and is used to adjust the heat dissipation status of the cabinet 1 in real time.

[0045] Specifically, the temperature control module includes: two heat dissipation components 4, a fan 7, and an adjustment mechanism 8;

[0046] Two heat dissipation components 4 are symmetrically arranged on both sides of the cabinet 1; the guide fan 7 is fixedly installed inside the cabinet 1; the adjustment mechanism 8 is fixed on the inner wall of the cabinet 1 and connected to the heat dissipation components 4, and is used to adjust the opening and closing degree of the heat dissipation components 4 according to the internal temperature of the cabinet 1.

[0047] When in operation, the continuous operation of electrical component module 6 will generate heat, which accumulates inside cabinet 1, causing the temperature inside cabinet 1 to rise continuously.

[0048] When the temperature inside the cabinet 1 is monitored, the adjustment mechanism 8 adjusts the opening and closing degree of the heat dissipation component 4, thereby cooperating with the guide fan 7 to improve the air convection efficiency inside the cabinet 1. This effectively improves the heat dissipation effect of the air on the electrical component module 6, keeps the electrical component module 6 within the normal temperature range, and avoids the signal detection module 6 from malfunctioning due to excessive temperature.

[0049] When the temperature of the electrical component module 6 rises abnormally and the temperature cannot be reduced to a reasonable operating range by the guide fan 7 and the heat dissipation component 4, the continuous temperature rise will cause the regulating mechanism 8 to spray flame-retardant material. At the same time, the regulating mechanism 8 will shut down the heat dissipation component 4, keeping the cabinet 1 in a closed state and blocking air circulation, which further prevents the occurrence of fire accidents and improves the safety of equipment use.

[0050] In a preferred embodiment, the heat dissipation component 4 includes:

[0051] The mounting frame 41 is fixed on the cabinet 1, and multiple air guide blades 42 are rotatably arranged inside it; drive components 43 are provided at both ends of the air guide blades 42, and the drive components 43 are connected to the adjustment mechanism 8 through the slide groove 44, which is formed on the mounting frame 41.

[0052] In a preferred embodiment, the adjustment mechanism 8 includes: a temperature control component 81, an adjustment component 82, and a push plate 83;

[0053] The temperature control component 81 is fixed on the inner wall of the cabinet 1 and is slidably connected to one end of the adjustment component 82; the other end of the adjustment component 82 is fixedly connected to the push plate 83, and the push plate 83 is connected to the drive component 43.

[0054] It should be noted that the temperature control component 81 senses the temperature change inside the cabinet 1 and drives the adjustment component 82 based on the temperature change. This causes the adjustment component 82 to control the drive component 43 through the push plate 83. Under the action of the drive component 43, the opening and closing degree of the air guide vane 42 is adjusted. That is, the air guide vane 42 is adjusted by the temperature inside the cabinet 1, thereby achieving the control of the air convection rate.

[0055] When the machine is stopped, the opening degree of the air guide vane 42 is zero, that is, the cabinet 1 is in a closed state under the action of the air guide vane 42, thereby preventing dust from entering.

[0056] In a preferred embodiment, the temperature control component 81 includes:

[0057] The housing 811 is fixed to the cabinet 1 by a fixing seat 812. One end of the piston rod 813 is slidably disposed inside the housing 811, and the other end of the piston rod 813 is connected to the adjusting assembly 82.

[0058] The nozzle 814 is fixed on the housing 811.

[0059] In a preferred embodiment, the sealed space formed by the housing 811 and the piston rod 813 is filled with liquid perfluorohexanone.

[0060] During operation, the temperature change inside the cabinet 1 causes the vaporization effect of liquid perfluorohexanone to change continuously. Even if the pressure in the sealed space changes according to the temperature, it will push the piston rod 813 to slide inside the housing 811. The sliding drive adjustment component 82 of the housing 811 will cause the push plate 83 to adjust the opening and closing angle of the guide vane 42 according to the temperature change of the cabinet 1 through the drive component 43, thereby achieving control of the air circulation efficiency.

[0061] As the temperature rises, the speed of the guide fan 7 is increased to enhance the air suction effect. At the same time, by increasing the opening angle of the guide vanes 42, the resonance between the air and the guide vanes 42 is reduced, thereby reducing the decibel of heat dissipation noise.

[0062] When the temperature inside the cabinet 1 exceeds the safety threshold, the vaporization of perfluorohexanone reaches its limit, thereby pushing the piston rod 813 to move to its limit position inside the housing 811. At this point, the perfluorohexanone inside the housing 811 will be sprayed through the nozzle 814 onto the electrical device module 6 and the entire cabinet 1. Simultaneously, due to the spraying of perfluorohexanone, the air guide vanes 42 are closed synchronously under the action of the regulating component 82, so that the cabinet 1 is isolated from the air while preventing the perfluorohexanone from escaping, further preventing the occurrence of fire and improving the safety of use.

[0063] In a preferred embodiment, the adjustment assembly 82 includes: a slide cylinder 821, a compression spring 822, and a guide rod 823;

[0064] One end of the slide cylinder 821 is slidably sleeved on the piston rod 813, and the other end is fixedly provided with one end of the guide rod 823. The other end of the guide rod 823 is connected to the push plate 83.

[0065] One end of the compression spring 822 is fixedly mounted on the slide cylinder 821, and the other end is connected to the piston rod 813.

[0066] In a preferred embodiment, the driving component 43 includes:

[0067] Gear 431 is coaxially fixed at both ends of the air guide blade 42;

[0068] The rack 432 is slidably disposed within the mounting frame 41 and meshes with the gear 431; the rack 432 is also fixedly connected to the push plate 83.

[0069] A return spring is provided between the rack 432 and the mounting frame 41.

[0070] During normal operation, the movement of piston rod 813 causes slide cylinder 821 to push guide rod 823 through compression spring 822. During the movement of guide rod 823, rack 432 slides. The sliding of rack 432 drives gear 431 to rotate, thereby adjusting the opening degree of guide vane 42.

[0071] When the opening angle of the air guide vane 42 is perpendicular to the mounting frame 41, this is the maximum opening angle of the air guide vane 42, and the rack 432 cannot move within the mounting frame 41; at the same time, the temperature inside the cabinet 1 is at a safe threshold in this state.

[0072] When the temperature exceeds the safety threshold, the vaporization of perfluorohexanone will continue to push the piston rod 813. When the piston rod 813 slides to the nozzle, perfluorohexanone is sprayed out to cover the entire interior of the cabinet 1, thereby achieving a flame-retardant effect.

[0073] As perfluorohexanone flows out of the housing 811, the rack 432 slides under the action of the return spring, thereby restoring the air guide vane 42 to its initial state. Even if the air guide vane 42 completely seals the cabinet 1 to isolate the air, it further hinders the possibility of fire.

[0074] In a preferred embodiment, the adjustment mechanism 8 is provided on both the upper and lower sides of the heat dissipation component 4 to monitor the internal temperature of the cabinet 1 in zones, improve the temperature control inside the cabinet 1, and thereby reasonably adjust the opening and closing angle of the air guide blades 42 to improve heat dissipation efficiency.

[0075] In a preferred embodiment, a power interface 5 is also provided on the cabinet 1.

[0076] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
