Description

Technical Field

[0001] This application relates to the field of control cabinets, and more specifically, to physically isolated fire control cabinets. Background Technology

[0002] Fire control cabinets are the core equipment of automatic fire alarm systems, integrating high-voltage control units (such as main / standby power switches, circuit breakers, relays, etc.) and low-voltage control units (such as central processing units, signal acquisition modules, communication modules, etc.). Currently, most fire control cabinets on the market are of an integrated structure, with high-voltage and low-voltage modules mixed and installed in the same cabinet.

[0003] In practical use, the high-voltage module generates a strong electromagnetic field when it is working, which can interfere with sensitive low-voltage signals, potentially causing false alarms or communication interruptions and affecting the reliability of the fire protection system. At the same time, the high-voltage module generates a lot of heat and shares the heat dissipation duct with the low-voltage module, which may lead to excessively high local temperatures inside the cabinet and affect the service life of the low-voltage components. To address this, we have proposed a physically isolated fire control cabinet. Utility Model Content

[0004] To address the above shortcomings, this application provides a physically isolated fire control cabinet, which aims to improve the problem of poor heat dissipation structure in existing fire control cabinets.

[0005] This application provides a physically isolated fire control cabinet, including a cabinet body. A partition is installed on the inner wall of the cabinet body, which divides the interior of the cabinet body into a low-voltage chamber and a high-voltage chamber. An air intake component is connected to the top of the cabinet body, and the air intake component is connected to the top of the low-voltage chamber and the high-voltage chamber. Drying components are installed on the side walls at both ends of the cabinet body, and the drying components are connected to the low-voltage chamber and the high-voltage chamber.

[0006] In one specific implementation, the air intake assembly includes two mounting tubes, which are respectively connected to the top of the weak current chamber and the strong current chamber, and each mounting tube is equipped with a cooling fan.

[0007] In one specific implementation, a waterproof cap is fixedly installed on the top of the mounting pipe, and an air outlet is provided on the side wall of the mounting pipe.

[0008] In one specific implementation, the drying assembly includes two breathable and waterproof covers, which are detachably connected to the two end side walls of the cabinet. The two breathable and waterproof covers are respectively connected to the weak current chamber and the strong current chamber. A support frame is inserted inside each of the two breathable and waterproof covers, and a drying package is placed on the support frame.

[0009] In one specific implementation, the support frame includes an assembly plate inserted into the breathable and waterproof cover. Several support plates are fixedly installed on one side wall of the assembly plate, and the drying package is placed on several of the support plates. Several through holes are provided on the assembly plate.

[0010] In one specific implementation, a dustproof net is also inserted inside the breathable and waterproof cover, the dustproof net is in contact with the assembly plate, and air inlets are provided on both the front and rear surfaces of the breathable and waterproof cover.

[0011] In one specific implementation, two L-shaped limiting plates are fixedly installed on the side wall of the cabinet, and the breathable and waterproof cover is inserted between the two L-shaped limiting plates.

[0012] In one specific implementation, through openings are provided on both ends of the cabinet sidewalls, and the through openings on both sides are respectively connected to the weak current chamber and the strong current chamber, and two breathable and waterproof covers are provided on the through openings on both sides.

[0013] In one specific implementation, guide rails are installed on the inner walls of both the weak current chamber and the strong current chamber, and accessory brackets are slidably connected to the guide rails.

[0014] In one specific implementation, limit blocks are fixedly installed at the bottom of both the weak current chamber and the strong current chamber. A limit groove is formed on the top of the limit block, and a rod slides through one side wall of the limit groove. A pulling block is fixedly connected to one end of the rod, and a spring is connected between the pulling block and the limit block. The bottom of the accessory bracket is inserted into the limit groove, and one end of the rod is inserted into the bottom of the accessory bracket.

[0015] The beneficial effects of this application are as follows: By installing partitions on the inner wall of the cabinet, the weak current chamber and the strong current chamber are physically isolated. The top of the cabinet is connected to the air intake component, and drying components are installed on the side walls at both ends of the cabinet. The air in the weak current chamber and the strong current chamber is discharged through the air intake component, so that the outside air enters the weak current chamber and the strong current chamber after passing through the drying component, thereby completing the heat dissipation inside the cabinet. At the same time, it is ensured that the air entering the cabinet is in a dry state to avoid affecting the internal components. By inserting a dustproof net inside the breathable and waterproof cover, impurities in the air can be filtered to prevent impurities from entering the cabinet and affecting the internal components.

Detailed Implementation

[0019] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0020] Please see Figure 1-5This application provides a physically isolated fire control cabinet, including a cabinet body 10. A partition 20 is installed on the inner wall of the cabinet body 10. Specifically, the partition 20 is made of metal and divides the interior of the cabinet body 10 into a low-voltage chamber 30 and a high-voltage chamber 40, thereby achieving physical isolation between the low-voltage chamber 30 and the high-voltage chamber 40. It should be noted that the partition 20 is connected to an existing grounding terminal located on the back of the cabinet body 10 via a wire. An air intake assembly 50 is connected to the top of the cabinet body 10, and the air intake assembly 50 is connected to the low-voltage chamber 30. The air intake component 50 is connected to the top of the high-voltage chamber 40. Specifically, the air intake component 50 is used to absorb the air in the low-voltage chamber 30 and the high-voltage chamber 40. Drying components 60 are installed on the side walls at both ends of the cabinet 10. The drying components 60 are connected to the low-voltage chamber 30 and the high-voltage chamber 40. So when the pressure in the low-voltage chamber 30 and the high-voltage chamber 40 decreases, outside air enters the low-voltage chamber 30 and the high-voltage chamber 40 through the drying components 60, so as to realize the air flow in the low-voltage chamber 30 and the high-voltage chamber 40 and achieve the purpose of heat dissipation.

[0021] See Figure 2 The air intake assembly 50 includes two mounting pipes 510, which are respectively connected to the top of the low-voltage chamber 30 and the high-voltage chamber 40. Each mounting pipe 510 is equipped with a cooling fan 520. Specifically, the two cooling fans 520 work synchronously to circulate air within the two mounting pipes 510, thereby causing air inside the cabinet 10 to flow into the two mounting pipes 510 and allowing outside air to enter the cabinet 10, thus ventilating and dissipating heat inside the cabinet 10. Furthermore, a waterproof cap 530 is fixedly installed on the top of the mounting pipe 510, and an air outlet 540 is opened on the side wall of the mounting pipe 510. By installing the waterproof cap 530 on the top of the mounting pipe 510, water can be prevented from entering the mounting pipe 510 through the air outlet 540.

[0022] See Figure 2 , 35. The drying assembly 60 includes two breathable and waterproof covers 610, which are detachably connected to the side walls at both ends of the cabinet 10. During installation, the breathable and waterproof covers 610 can be removed from the side walls of the cabinet 10. The two breathable and waterproof covers 610 are respectively connected to the low-voltage chamber 30 and the high-voltage chamber 40. Each of the two breathable and waterproof covers 610 has a support frame 620 inserted inside, on which a drying package 630 is placed. Specifically, by removing the breathable and waterproof cover 610 from the side wall of the cabinet 10, the support frame 620 can be pulled out from inside the breathable and waterproof cover 610, allowing the drying package 630 on the support frame 620 to be replaced. Further, the support frame 620 includes an assembly plate 6210, which is inserted into the breathable and waterproof cover 610 and slides in contact with the inner wall of the breathable and waterproof cover 610. Several support plates 6220 are fixedly installed on one side wall of the cabinet 10. A desiccant pack 630 is placed on the support plates 6220. Specifically, several desiccant packs 630 are provided and placed on the support plates 6220. The desiccant packs 630 are filled with desiccant. Several through holes 6230 are opened on the assembly plate 6210. Outside air enters the breathable and waterproof cover 610, is dried by the desiccant packs 630, and then enters the cabinet 10 through the through holes 6230. Furthermore, a dustproof net 640 is inserted into the breathable and waterproof cover 610. The dustproof net 640 is in contact with the assembly plate 6210. Air inlets 650 are opened on both the front and back surfaces of the breathable and waterproof cover 610. The dustproof net 640 can be pulled out from the breathable and waterproof cover 610 for easy cleaning. Outside air enters the breathable and waterproof cover 610 through the air inlets 650.

[0023] See Figure 3 and 5 Two L-shaped limiting plates 110 are fixedly installed on the side wall of the cabinet 10. A breathable and waterproof cover 610 is inserted between the two L-shaped limiting plates 110. In the specific installation, connecting plates are fixedly installed on the top and bottom of the breathable and waterproof cover 610. The two connecting plates are inserted into the two L-shaped limiting plates 110 respectively to facilitate the disassembly and assembly of the breathable and waterproof cover 610. Furthermore, through openings 120 are provided on the side walls at both ends of the cabinet 10. The two through openings 120 are respectively connected to the weak current chamber 30 and the strong current chamber 40. The two breathable and waterproof covers 610 are closed on the two through openings 120. Specifically, the air inside the breathable and waterproof cover 610 enters the cabinet 10 through the through openings 120.

[0024] See Figure 2 and 4Guide rails 70 are installed on the inner walls of both the low-voltage chamber 30 and the high-voltage chamber 40. Accessory brackets 710 are slidably connected to the guide rails 70. Several guide rails 70 are provided, and sliding grooves are formed on the side walls of the guide rails 70. The side walls of the accessory brackets 710 are slidably disposed within the sliding grooves. Furthermore, limit blocks 80 are fixedly installed at the bottom of both the low-voltage chamber 30 and the high-voltage chamber 40. Limit grooves 810 are formed on the top of the limit blocks 80, and insertion rods 820 slide through the side walls of one end of the limit grooves 810. A pull block 830 is fixedly connected to one end of 820. A spring 840 is connected between the pull block 830 and the limit block 80. The bottom of the accessory bracket 710 is inserted into the limit groove 810. One end of the insertion rod 820 is inserted into the bottom of the accessory bracket 710. In a specific setting, an insertion hole is opened on the side wall of the bottom of the accessory bracket 710. One end of the insertion rod 820 is inserted into the insertion hole to cooperate with the guide rail 70. Fixing the accessory bracket 710 also facilitates the assembly and disassembly of the accessory bracket 710.

[0025] When this physically isolated fire control cabinet is in operation: the accessory bracket 710 is installed inside the cabinet 10, the side wall of the accessory bracket 710 is inserted into the guide rail 70, and then the insertion rod 820 is used to fix the accessory bracket 710 to complete the installation of the accessory bracket 710. The accessory installation structure of the cabinet 10 is existing technology. When the accessories inside the cabinet 10 are working, the cooling fans 520 on both sides are started. The cooling fans 520 work to make the air flow in the installation pipe 510, so that the air inside the cabinet 10 flows into the installation pipe 510, thereby reducing the air pressure inside the cabinet 10, allowing outside air to enter the breathable waterproof cover 610 through the air inlet 650, the air flows through the support plate 6220, is dried by the drying bag 630, and then passes through the through hole 6230 and the dustproof net 640, so that the air enters the cabinet 10 through the through hole 120 to ventilate and dissipate heat inside the cabinet 10.

[0026] It should be noted that the specific model and specifications of the cabinet 10 and the cooling fan 520 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0027] The power supply and operating principle of the cabinet 10 and the cooling fan 520 are clear to those skilled in the art, and will not be described in detail here.

[0028] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
