Description

Technical Field

[0001] This invention relates to the field of multi-fuel leak detection, and more specifically to a multi-fuel leak detection alarm device. Background Technology

[0002] Currently, the catering industry mostly uses alcohol-based fuels and alkyl fuels, which have the following advantages: alkyl fuels and alcohol-based fuels have low fuel costs and are more environmentally friendly than coal.

[0003] Therefore, alkyl and alcohol-based fuels are currently widely used in the catering industry. However, multi-fuel stoves using alkyl and alcohol-based fuels pose a risk of leakage. If a leak is not detected in time, it can easily explode upon contact with an open flame once it reaches a certain level, endangering personal safety. Therefore, the detection of alkyl and alcohol-based fuel leaks is particularly important, and there is an urgent need for a multi-fuel leak detection and alarm device. Summary of the Invention

[0004] This invention overcomes the shortcomings of existing single-fuel detection technologies used in the catering industry and provides a multi-fuel leak detection and alarm device.

[0005] The objective of this invention is achieved through the following technical solution.

[0006] A multi-fuel leak detection and alarm device includes: an intrinsically safe explosion-proof housing, a power module, an alkanoyl group detection device, a processor, a signal transceiver conversion device, and a display device. The intrinsically safe explosion-proof housing houses the power module, the alkanoyl group detection device, the processor, and the signal transceiver conversion device. The power module is electrically connected to the alkanoyl group detection device, the processor, the signal transceiver conversion device, and the display device. The alkanoyl group detection device is electrically connected to the processor, the processor is electrically connected to the signal transceiver conversion device, and the signal transceiver conversion device is electrically connected to the display device.

[0007] The processor is connected to the indicator light circuit.

[0008] The signal transceiver conversion device uses a CAN transceiver.

[0009] The display section of the display device is located on the outer surface of the intrinsically safe explosion-proof enclosure.

[0010] The intrinsically safe explosion-proof enclosure is made of intrinsically safe explosion-proof material.

[0011] The beneficial effects of this invention are as follows:

[0012] This solution, through the combination of an alkyl alcohol group detection device, a processor, and a display device, can effectively monitor multi-fuel devices such as multi-fuel stoves in real time and provide timely reminders to users. It effectively reduces the leakage risk associated with the use of alkyl or alcohol groups as fuels.

[0019] Example 1

[0020] A multi-fuel leak detection and alarm device includes: an intrinsically safe explosion-proof housing 1, a power module 2, an alkanoyl group detection device 3, a processor 4, a signal transceiver conversion device 5, and a display device 6. The intrinsically safe explosion-proof housing 1 houses the power module 2, the alkanoyl group detection device 3, the processor 4, and the signal transceiver conversion device 5. The power module 2 is electrically connected to the alkanoyl group detection device 3, the processor 4, the signal transceiver conversion device 5, and the display device 6. The alkanoyl group detection device 3 is electrically connected to the processor 4. The processor 4 is electrically connected to the signal transceiver conversion device 5. The signal transceiver conversion device 5 is electrically connected to the local display device 6.

[0021] The signal transceiver conversion device 5 uses a CAN transceiver.

[0022] The display section of the local display device 6 is disposed on the outer surface of the intrinsically safe explosion-proof housing 1.

[0023] The intrinsically safe explosion-proof enclosure 1 is made of intrinsically safe explosion-proof material.

[0024] This invention is mainly used by civilian catering establishments and users to report relevant signals and trigger alarms when using multi-fuel (alkyl, alcohol-based) stoves to detect leaks.

[0025] like Figure 1 As shown, the working principle of this invention is as follows. The power module 2 installed inside the intrinsically safe explosion-proof housing 1 supplies power to the alkanoyl group detection device 3, processor 4, signal transceiver conversion device 5, and display device 6. The alkanoyl group detection device 3 monitors the fuel pipeline and sends an electrical signal corresponding to the amount of alcohol-based fuel leakage to the processor 4. The processor 4 converts the received detection signal into a corresponding digital signal and sends the digital signal to the signal transceiver conversion device 5. The signal transceiver conversion device 5 converts the received digital signal into corresponding message information and sends the message information to the display device 6 for display, achieving a visual observation function.

[0026] In this embodiment, the alkanoyl group detection device 3 is an existing alkanoyl and alcohol group detection instrument, and the processor 4 uses a PLC as the processor. In production, other processors can be used depending on the specific environment. The signal transceiver conversion device 5 uses a CAN transceiver to convert the received digital signals into corresponding message information and send them.

[0027] Furthermore, when the processor 4 detects an abnormality in the detection signal, it sends a first digital signal to the signal transceiver conversion device 5, causing the signal transceiver conversion device 5 to convert the first digital signal into a first message. When the display device 6 receives the first message sent by the signal transceiver conversion device 5, it broadcasts a fault prompt message via voice. For example, after receiving the first message sent by the signal transceiver conversion device 5, the display device 6 can broadcast a fault prompt message such as "Current detection is abnormal" to alert personnel that the alkane and alcohol leakage detection equipment has malfunctioned.

[0028] Furthermore, based on this, the processor 4 can be electrically connected to the valve of the alkane and alcohol storage device, allowing the processor 4 to control it. When the processor 4 receives a detection signal, it determines whether the concentration of the alkane and alcohol fuel is greater than or equal to a preset concentration threshold. If so, it controls the valve of the alkane and alcohol storage device to close, achieving an emergency shutdown of alkane and alcohol leakage. This structure enables the device to control the valve of the alcohol storage device when it detects that the concentration of alkane and alcohol is greater than or equal to the preset concentration threshold, causing it to close in time and preventing alcohol fuel leakage and explosion accidents.

[0029] Preferably, the alkyl group concentration detection thresholds are 5% ≤ CH4 ≤ 15%, 3% ≤ CH3CH3 ≤ 12%, 2.1% ≤ CH3CH2CH3 ≤ 9.5%, and 3% ≤ C4H10 ≤ 12%; the alcohol group concentration detection threshold is 35 ppm ≤ CH3OH.

[0030] Example 2

[0031] Based on Embodiment 1, the processor 4 is connected to the indicator light 7 in a circuit.

[0032] In this embodiment, the processor 4 converts the received detection signal into a corresponding pulse voltage and sends the corresponding pulse voltage to the indicator light 7, causing the indicator light 7 to flash at the corresponding frequency.

[0033] In this embodiment, three pulse voltages are used as an example. The processor 4 outputs three pulse voltages to the indicator light 7 according to the different detection signals received, namely, the first, second and third pulse voltages.

[0034] Specifically, when indicator light 7 receives a first pulse voltage, it will flash accordingly, for example, it will be on for 2 seconds and off for 2 seconds, which corresponds to an abnormal detection signal.

[0035] When indicator light 7 receives a second pulse voltage, it will flash accordingly, for example, it will be on for 1 second and off for 3 seconds, which corresponds to the normal concentration of alkane and alcohol fuel.

[0036] When indicator light 7 receives a pulse voltage with a third pulse, it will flash accordingly, for example, flashing rapidly for 0.25 seconds on and 0.25 seconds off, corresponding to the concentration of alkane or alcohol-based fuel leakage exceeding the preset gas concentration threshold.

[0037] This structure, by setting up indicator lights 7, flashes at corresponding frequencies according to the different concentrations of alcohol-based fuels, allowing catering staff to more intuitively understand the leakage status of alkane and alcohol-based fuels, and also to intuitively understand whether the current fuel leak detection equipment is malfunctioning.

[0038] Preferably, indicator light 7 is a diode, which will flash at different frequencies when it receives different pulse voltages.

[0039] Example 3

[0040] like Figure 3 As shown, based on Embodiment 2, the processor 4 is also connected to the remote explosion-proof LED screen 8 circuit, which includes a buzzer alarm. This structure, by setting up the remote explosion-proof LED screen 8, provides audible and visual alarms at corresponding frequencies based on the different concentrations of alkane and alcohol-based fuels. This allows catering personnel to more intuitively understand the leakage status of alkane and alcohol-based fuels, and also to intuitively understand whether the current fuel leak detection equipment is malfunctioning.

[0041] Compared to Embodiment 2, in this embodiment, catering staff can remotely set and shut down the detection thresholds for alkane and alcohol leaks via the explosion-proof LED screen 8; set the frequency and volume of the audible and visual alarms; and perform a reset operation after an alkane or alcohol fuel leak alarm.

[0042] Example 4

[0043] like Figure 4 As shown, based on Embodiment 3, the processor 4 is also connected to the Nb transmission module 9.

[0044] Compared to embodiment three, in this embodiment, when the processor 4 detects an abnormal detection signal, it also communicates the signal with the mobile phone through the Nb transmission module. In this embodiment, catering staff can remotely and wirelessly control the leakage of alkane and alcohol fuels at night or when no one is on duty through a mobile APP.

[0045] Example 5

[0046] like Figure 5 As shown, based on Embodiment 4, the processor 4 is also connected to the CCTV acquisition module 10.

[0047] Compared to embodiment four, in this embodiment, when the CCTV acquisition module detects personnel misoperation or unsafe behavior, the processor 4 triggers the transmission module and broadcasts a voice message to reduce the output of unsafe behavior.

[0048] Example 6

[0049] Based on Embodiment 5, processor 4 employs an enhanced embedded edge computing component.

[0050] Compared to embodiment five, in this embodiment, the processor can collect data such as gas usage habits and gas consumption while working, and create a profile of the gas usage habits of catering customers, thereby enabling high-frequency detection during peak gas usage times and improving detection efficiency.

All equivalent changes and improvements made in accordance with the scope of the present invention should still fall within the patent coverage of the present invention.
