Description

Technical Field

[0001] This utility model relates to a controller, and more particularly to an outdoor gas alarm controller. Background Technology

[0002] A gas alarm is a gas leak detection and alarm instrument. When a flammable or toxic gas leaks in an industrial environment, and the gas alarm detects that the gas concentration has reached the critical point set by the explosion or poisoning alarm, the alarm will sound an alarm signal to remind workers to take safety measures and activate ventilation, shut-off, and sprinkler systems to prevent explosions, fires, or poisoning accidents, thereby ensuring safe production.

[0003] Most gas alarm controllers on the market are currently designed for indoor use and are not waterproof.

[0004] Currently, most outdoor gas alarm controllers on the market rely solely on ventilation louvers for waterproofing on both sides. Better models may have a rainproof cover on top, but this structure only meets the IP53 protection level for light rain splashes. In severe weather conditions like strong winds and heavy rain, it cannot effectively prevent rainwater from entering the controller from below. Furthermore, adding a rainproof cover increases product and installation costs. The numerous electrical devices and wiring connections within outdoor controllers have stringent safety requirements. If rainwater seeps into the controller housing, it can affect the electrical equipment and wiring, causing short circuits. This not only disrupts normal power supply but also increases the risk of fire, seriously impacting industrial safety.

[0005] The outdoor environment is complex. In addition to being waterproof, outdoor gas alarm controllers also need to withstand harsh conditions such as humidity and heat. Therefore, the service life of existing gas alarm controllers placed outdoors is relatively short. Utility Model Content

[0006] The purpose of this invention is to provide an outdoor gas alarm controller that has the advantages of heat dissipation and waterproofing, effectively solving the problem in the prior art that it cannot effectively prevent rainwater from entering the controller from the top during severe weather such as wind and heavy rain.

[0031] Please see Figure 1-11 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0032] The outdoor gas alarm controller of this utility model includes a base shell 1, and an upper cover 2 and a lower cover 3 hinged to the front side of the base shell 1. A display screen 4 is fixedly embedded inside the upper cover 2. Several external ventilation openings 5 ​​are provided on both the left and right sides of the base shell 1. A first cover 6 is fixedly provided on both the left and right sides of the base shell 1 above each external ventilation opening 5. Electrical equipment is installed inside the base shell 1. Two partitions 7 are fixedly provided on the inner bottom wall of the base shell 1 in the vertical direction. Each partition 7 is parallel to the inner side wall of the base shell 1. Each partition 7 forms a waterproof interlayer space 10 with the corresponding inner side wall. An internal ventilation opening 8 is provided on each partition 7. The internal ventilation opening 8 and the external ventilation opening 5 are staggered vertically. An overflow hole 9 communicating with the waterproof interlayer space 10 is provided on the bottom surface of the base shell 1.

[0033] In use, the top cover 2 is normally locked and does not need to be opened. For on-site wiring or after-sales maintenance, only the bottom cover 3 needs to be opened. During normal use, heat inside the bottom shell 1 enters the waterproof interlayer space 10 through the inner vent 8, and then dissipates to the outside through the outer vent 5, achieving heat dissipation. On rainy days, rainwater may enter the first cover 6 from below, and then enter the waterproof interlayer space 10 through the outer vent 5. The rainwater entering the waterproof interlayer space 10 flows downwards from the overflow hole 9 on the bottom surface of the bottom shell 1. The waterproof interlayer space 10 effectively prevents rainwater from entering the interior of the bottom shell 1, avoiding its impact on electrical equipment or wiring, and preventing short circuits. This would affect the normal operation of electricity and could easily cause fires, seriously impacting industrial safety.

[0034] In this embodiment, multiple internal ventilation openings 8 are opened on the partition 7 in the vertical direction, and a second cover 11 is fixedly installed on the partition 7 above each internal ventilation opening 8. By setting the second cover 11, rainwater entering the waterproof interlayer space 10 is prevented from entering the space between the two partitions 7 through the internal ventilation opening 8, thereby avoiding the impact on electrical equipment.

[0035] Over time, dust and solid objects can easily accumulate in the waterproof interlayer space 10, reducing its heat dissipation function. Foreign objects can also easily clog the overflow hole 9. To address this issue, in this embodiment, the partition 7 includes a side plate 12, end plates 13 fixed at both ends, and a top plate 14 fixed to the front of the side plate 12. The inner vent 8 and the second cover 11 are both located on the side plate 12. The outer side of the top plate 14 is flush with the inner wall of the bottom shell 1. A waterproof interlayer space 10 is formed between the side plate 12, end plates 13, top plate 14, and the side wall of the bottom shell 1. The overflow hole 9 is located on the lower end plate 13. Mounting holes 15, which are adapted to the end plates 13, are provided on both the upper and lower surfaces of the bottom shell 1. The end plates 13 are fixedly installed within the corresponding mounting holes 15.

[0036] When installing the partition 7, insert the partition 7 into the mounting hole 15 at the upper or lower end of the bottom shell 1, so that the side plate 12, end plate 13 and top plate 14 pass through the mounting hole 15 until the lower end plate 13 is located in the lower mounting hole 15 and the upper end plate 13 is located in the upper mounting hole 15. Then, fix the end plate 13 to the bottom shell 1 with bolts to realize the installation of the partition 7. Long-term use requires regular cleaning of the waterproof interlayer space 10. When a large amount of foreign matter accumulates in the waterproof interlayer space 10, the bolts are removed to release the fixed relationship between the end plate 13 and the bottom shell 1. Then, the side plate 12 is pulled up or down to realize the disassembly of the partition 7, which facilitates the cleaning of the waterproof interlayer space 10. At the same time, the side plate 12, end plate 13 and top plate 14 are cleaned from the outside before the partition 7 is installed into the bottom shell 1.

[0037] In this embodiment, an extension portion 16 extending inward by a predetermined distance is provided on the front side of the side wall of the bottom shell 1 corresponding to the partition 7. A lock cylinder 17 is installed on both the upper cover 2 and the lower cover 3. A lock tongue 18 is fixedly provided at the rear end of the lock cylinder 17. When the upper cover 2 and the lower cover 3 are closed, the lock cylinder 17 is rotated by using a key to drive the lock tongue 18, so that the outer end of the lock tongue 18 enters the rear of the extension portion 16, thereby locking the upper cover 2 and the lower cover 3. When it is necessary to open the upper cover 2 and the lower cover 3, the lock cylinder 17 is rotated to drive the lock tongue 18, so that the outer end of the lock tongue 18 exits the rear of the extension portion 16, and then the upper cover 2 and the lower cover 3 can be opened.

[0038] In this embodiment, a set distance is provided between the front side of the top plate 14 and the rear side of the extension 16, so as not to interfere with the locking tongue 18 entering and exiting the rear of the extension 16.

[0039] In this embodiment, a spacer 19 is fixedly provided on the front side of the bottom shell 1, and a sealing strip 20 corresponding to the upper cover 2 and the lower cover 3 is fixedly provided on the front side of the bottom shell 1. A sealing groove 21 adapted to the sealing strip 20 is opened on the rear side of the upper cover 2 and the lower cover 3. When the upper cover 2 and the lower cover 3 are closed, the sealing strip 20 enters the sealing groove 21, thereby sealing the upper cover 2 and the lower cover 3 with the bottom shell 1 and ensuring water tightness.

[0040] In this embodiment, the electrical equipment includes a main control PCB board and a power supply 22 installed inside the bottom shell 1. A waterproof connector 23 is fixedly installed on the lower end face of the bottom shell 1. When wiring, the wires pass through the waterproof connector 23 and are electrically connected to the terminals of the main control PCB board. The waterproof connector 23 is a commercially available product with waterproof function. It is existing technology and will not be described in detail here.

[0041] To facilitate the connection of wires to the main control PCB board, in this embodiment, a rectangular opening 24 is provided on the lower end face of the bottom shell 1 below the waterproof connector 23. The sealing plate 25 located in the rectangular opening 24 is fixedly installed with the bottom shell 1. When wiring is required, the sealing plate 25 is first opened, then the wire is passed through the waterproof connector 23, and then the wire and the main control PCB board are electrically connected through the rectangular opening 24. Currently, gas alarm controllers on the market, when facing multi-channel users, usually have knockout holes designed at the bottom of the bottom shell 1 to meet customer wiring needs. Indoor knockout holes have obvious penetration gaps and are not completely filled with powder coating, making knocking them out relatively simple. However, outdoor knockout holes are filled with powder coating after spraying, and only the knockout gaps are visible. This type of outdoor knockout hole is difficult to knock out, making the operation difficult. By setting the waterproof connector 23 and sealing plate 25 to replace the knockout holes on the outdoor bottom shell 1, the wiring efficiency is effectively improved.

[0042] In this embodiment, the electrical equipment also includes a backup battery 26 and a backup PCB board installed in the bottom shell 1. The backup battery 26, the backup PCB board, the power supply 22 and the main control PCB board are all provided with protective covers 27, and the protective covers 27 are fixedly installed to the inner bottom wall of the bottom shell 1.

[0043] In this embodiment, an indicator light PCB board 28 is fixedly installed on the rear side of the upper cover 2. A buzzer 29, a voice speaker 30, and several status indicator lights 31 are installed on the indicator light PCB board 28. The front side of the upper cover 2 has through holes that are compatible with the buzzer 29, the voice speaker 30, and the status indicator lights 31. The buzzer 29, the voice speaker 30, and the status indicator lights 31 are all located in the corresponding through holes, which makes it easy to observe the color of the status indicator lights 31 and to facilitate the sound transmission of the buzzer 29 and the voice speaker 30.

[0044] In this embodiment, the upper cover 2 is provided with a display screen mounting groove 32 and a fixing plate mounting groove 33. The display screen 4 is fixedly embedded in the display screen mounting groove 32 by adhesive, and the fixing plate 34 is fixedly embedded in the fixing plate mounting groove 33 by adhesive.

[0045] The working principle of this utility model is as follows: The upper cover 2 is normally locked and does not need to be opened. For on-site wiring or after-sales maintenance, only the lower cover 3 needs to be opened. During normal use, heat inside the bottom shell 1 enters the waterproof interlayer space 10 through the inner vent 8, and then dissipates to the outside through the outer vent 5, achieving heat dissipation. On rainy days, rainwater may enter the first cover 6 from below, and then enter the waterproof interlayer space 10 through the outer vent 5. The rainwater entering the waterproof interlayer space 10 flows downwards from the overflow hole 9 on the bottom surface of the bottom shell 1. The waterproof interlayer space 10 effectively prevents rainwater from entering the interior of the bottom shell 1, thus preventing rainwater from affecting electrical equipment or wiring, causing short circuits, affecting normal power supply, and potentially causing fires, seriously impacting industrial safety.
