Description

Technical Field

[0001] This utility model relates to the field of smoldering detector technology, specifically to a mobile early smoldering detector. Background Technology

[0002] After large quantities of goods are stored, fires may occur due to improper storage, abnormal environments, or human factors. Cotton is a particularly serious agricultural product; a fire can destroy large quantities of cotton, impacting the economic interests of cotton farmers, and can also spread widely, endangering their personal safety. Therefore, it is necessary to monitor fire conditions during storage. Early smoldering fire detectors can detect fires as early as possible, allowing for timely intervention and ensuring uninterrupted operation. However, existing early smoldering fire detectors have the following drawbacks:

[0003] (1) Existing fixed early smoldering detectors are installed in fixed locations and can collect and detect data in real time in static warehouse spaces; however, when such equipment is used in temporary dynamic warehouses, it cannot meet the needs of changes in space and detection location, which causes inconvenience for early smoldering detection.

[0004] (2) Traditional smoke detectors detect particulate matter generated by smoldering. The gas characteristics such as PM2.5, CO, and VOCs generated in the early stage of smoldering cotton are not effectively monitored. The detection method is relatively simple, the response is delayed, and it is easy to cause false alarms.

[0005] Therefore, it is necessary to propose a mobile early smoldering detector to at least partially solve the problems existing in the prior art. Utility Model Content

[0034] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] Example

[0036] The present invention will now be further described with reference to the accompanying drawings.

[0037] like Figures 1-7 As shown, this embodiment provides a mobile early smoldering detector, comprising:

[0038] The outer casing 1 has a set of movable wheels 2 installed at the bottom. Inside the outer casing 1, there is an explosion-proof battery compartment 11 and a detection terminal 12, which are electrically connected. A telescopic sampling tube 10 is installed on the top surface of the outer casing 1. The telescopic sampling tube 10 passes through the outer casing 1 and is connected to the detection terminal 12. The detection terminal 12 is equipped with a gas sensor 12.4.3.1 and a particle sensor 12.4.3.2.

[0039] The working principle and beneficial effects of this utility model are as follows:

[0040] This embodiment provides a mobile early-stage smoldering detector. In use, the detector is moved to the desired location using external wheels 2. The length of the telescopic sampling tube 10 is adjusted, and its air inlet is positioned at the required detection height. The explosion-proof battery compartment 11 and detection terminal 12 are activated. The explosion-proof battery compartment 11 powers the detection terminal 12 via electrical connection. The detection terminal 12 then draws in gases from the surrounding environment through the telescopic sampling tube 10. Gas sensors 12.4.3.1 detect the concentrations of gases such as CO and VOCs generated in the early stages of smoldering, and particle sensors 12.4.3.2 detect the concentration of particulate matter in the surrounding environment. After use, the explosion-proof battery compartment 11 and detection terminal 12 are closed, and the telescopic sampling tube 10 is retracted to its initial length for easy movement.

[0041] Gas sensor 12.4.3.1 is configured as any one or more combinations of gas sensors such as PM2.5 gas sensor, CO gas sensor, and VOCs gas sensor.

[0042] The telescopic sampling tube 10 can adopt the telescopic joint tube structure as described in the utility model patent with application number CN202323602674.2, which includes no less than three telescopic tubes and can be locked by threads.

[0043] Through the above structural design, the mobile early smoldering detector provided in this embodiment has the following technical effects:

[0044] The instrument is equipped with a set of wheels 2 on the outside, which can move the detector at will and monitor the dynamic environment to be tested in real time.

[0045] The instrument is equipped with a telescopic sampling tube 10 on the outside to collect gas samples from the surrounding environment. The telescopic feature allows for the detection of areas at different heights, making it convenient for movement and transportation.

[0046] The instrument has an explosion-proof battery compartment 11 inside for powering the equipment, so that testing can be carried out in places without power supply;

[0047] The instrument's internal detection terminal 12 is equipped with a gas sensor 12.4.3.1 and a particle sensor 12.4.3.2, which can detect the concentration of gases such as CO and VOCs generated in the early stage of smoldering in the surrounding environment, as well as the concentration of particulate matter. By comparing the concentration data with preset data, the probability of smoldering can be determined, and accurate information can be obtained, reducing the occurrence of misjudgments due to single monitoring data.

[0048] The outer casing 1 has a handle 3 installed on the back, which facilitates the movement and arrangement of the early smoldering detector by the operator; a rear cover 4 is detachably installed below the handle 3 on the back of the outer casing 1 for convenient storage and installation of the explosion-proof battery compartment 11.

[0049] The outer casing 1 has an exhaust grille 1.1 on its side, which is used to exhaust gas and prevent other debris from entering the instrument.

[0050] The detection terminal 12 has a mounting hole on its back, which is connected to the outer shell 1 through a fixing piece 13.

[0051] In one embodiment, the detection terminal 12 includes a housing 12.1. Inside the housing 12.1 are a mounting plate 12.2, a main board 12.3, a detection chamber 12.4, an air inlet connector 12.5, and an air outlet connector 12.6. The mounting plate 12.2 is connected to the inner wall of the housing 12.1, and the main board 12.3 and the detection chamber 12.4 are connected to the mounting plate 12.2. The air inlet connector 12.5 is located at the top of the housing 12.1, and its two ends are connected to the telescopic sampling tube 10 and the detection chamber 12.4, respectively. The air outlet connector 12.6 is located at the side of the housing 12.1, and its two ends are connected to the detection chamber 12.4 and the housing 12.1, respectively.

[0052] The detection chamber 12.4 includes a gas filter chamber 12.4.1 and a gas sensor sensing chamber 12.4.3 arranged vertically, connected to each other. An air intake pump 12.4.2 is installed at the top of the gas sensor sensing chamber 12.4.3 and is electrically connected to the main board 12.3. The gas filter chamber 12.4.1 is connected to the telescopic sampling tube 10 via an air inlet connector 12.5. The gas sensor sensing chamber 12.4.3 is connected to the housing 12.1 via an air outlet connector 12.6. The gas sensor sensing chamber 12.4.3 contains a gas sensor 12.4.3.1 and a particle sensor 12.4.3.2.

[0053] The detection chamber 12.4 is externally provided with a detection chamber shell 12.4.5, and the detection chamber shell 12.4.5 is covered with a detection chamber upper cover plate 12.4.6 and a detection chamber lower cover plate 12.4.7; the detection chamber upper cover plate 12.4.6 corresponds to the position of the gas filter chamber 12.4.1, and the detection chamber lower cover plate 12.4.7 corresponds to the position of the gas sensor sensing chamber 12.4.3.

[0054] The gas filter chamber 12.4.1 is equipped with a filter screen 12.4.1.1. The bottom of the gas filter chamber 12.4.1 is connected to the air inlet of the air pump 12.4.2. The gas sensor sensing chamber 12.4.3 is connected to the air outlet of the air pump 12.4.2.

[0055] Among them, a baffle 12.4.3.3 is provided on one side of the bottom of the gas sensor sensing chamber 12.4.3. The baffle 12.4.3.3 guides the airflow to the gas outlet connector 12.6.

[0056] The working principle and beneficial effects of the above technical solution are as follows:

[0057] When the detection terminal 12 is in use, the mainboard 12.3 controls the start of the suction pump 12.4.2. The suction pump 12.4.2 generates suction force, drawing gas from the external environment through the telescopic sampling tube 10. After passing through the air inlet connector 12.5, the gas enters the gas filter chamber 12.4.1. Under the suction, the gas continues to flow downwards, passing through the filter screen 12.4.1.1 at the bottom of the gas filter chamber 12.4.1, which filters out impurities and large particles mixed in the gas, improving detection accuracy and preventing internal blockage of the instrument. Then the gas enters the gas sensor. Inside the sensor chamber 12.4.3, the gas sensor 12.4.3.1 and the particle sensor 12.4.3.2 detect the concentration of gases such as CO and VOCs generated in the early stage of smoldering, as well as the concentration of particulate matter. By comparing the concentration data with preset values, the probability of smoldering is determined, and accurate information is obtained, reducing the occurrence of misjudgments due to single monitoring data. After detection, the gas is guided by the baffle 12.4.3.3 and discharged from the chamber 12.1 through the gas outlet connector 12.6, and then discharged from the instrument through the gas outlet grille 1.1.

[0058] In one embodiment, a power switch 5, a power indicator light 6, a status indicator light 7, an audible and visual alarm light 8, and a 4G antenna 9 are installed on the top surface of the housing 1, and all of them are electrically connected to the motherboard 12.3.

[0059] The working principle and beneficial effects of the above technical solution are as follows:

[0060] The power switch 5 is used to turn on the detector and activate the explosion-proof battery compartment 11 and the detection terminal 12 of the detector.

[0061] Power indicator light 6 is used to indicate the power connection status of the detector;

[0062] Status indicator light 7 is used to indicate the working status of the detector;

[0063] The audible and visual alarm light 8 is used to indicate the smoldering state of the environment. When the concentration value detected by the detector exceeds the preset concentration value, smoldering occurs on the surface, and the audible and visual alarm light 8 is activated to sound an alarm.

[0064] After receiving a signal, the 4G antenna 9 transmits the signal to the cable, which then transmits the signal to the motherboard 12.3. Alternatively, the motherboard 12.3 transmits the signal to the 4G antenna 9 via the cable, and then sends the signal to the mobile terminal.
