Description

Technical Field

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

[0002] A fire during cargo storage can result in significant losses of goods and harm to the surrounding environment and workers. Therefore, fire monitoring devices should be installed in warehouses or temporary storage areas. Early smoldering fire detectors, in particular, can detect fires early, issuing timely alarms to alert staff or firefighters for rapid response and firefighting. However, existing early smoldering fire detectors have the following drawbacks:

[0003] (1) Once the existing fixed smoldering detectors are deployed, they are used for real-time monitoring within a certain area. When a smoldering alarm occurs, on-site personnel cannot carry the detectors to the alarm location to conduct investigations.

[0004] (2) Existing detectors use a single gas sensor, such as a CO sensor, which cannot detect multiple gases such as CO and VOC produced in the early stage of smoldering cotton and make a comprehensive judgment.

[0005] (3) The existing instruments do not integrate active air intake devices, so they cannot collect the gas in the surrounding environment in a timely manner and make a rapid judgment on the situation on site.

[0006] Therefore, it is necessary to propose a handheld, very early smoldering detector to at least partially solve the problems existing in the prior art. Utility Model Content

[0044] 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.

[0045] Example

[0046] The present invention will now be further described with reference to the accompanying drawings.

[0047] like Figures 1-4 As shown, this embodiment provides a handheld early smoldering detector, comprising:

[0048] The outer casing 1 has a handle 2 at its bottom and a detection chamber is formed inside the outer casing 1.

[0049] Mainboard 14 is installed inside the housing 1. Mainboard 14 contains air pump 12 and multiple gas sensors 15.

[0050] Telescopic sampling tube 9 is located on the top of housing 1 and connected to the air inlet of suction pump 12.

[0051] The working principle and beneficial effects of this utility model are as follows:

[0052] This embodiment provides a handheld early smoldering detector. In use, on-site personnel carry the detector to the alarm location for investigation. The personnel hold the instrument via handle 2; adjust the length of the telescopic sampling tube 9, positioning its inlet end to the desired detection position; start the detector, and the main board 14 controls the intake pump 12 and multiple gas sensors 15. Under the suction force of the intake pump 12, the end of the telescopic sampling tube 9 draws in gas from the surrounding environment. The multiple gas sensors 15 detect the concentration of particulate matter and gases such as CO and VOCs generated in the early stages of smoldering in the surrounding environment. After use, the detector power is turned off, and the telescopic sampling tube 9 is retracted to its initial length.

[0053] Gas sensor 15 is configured as any one or more combinations of gas sensors such as PM2.5 gas sensor, CO gas sensor, and VOCs gas sensor. Optionally, motherboard 14 is configured with a particulate sensor for detecting particulate matter concentration.

[0054] Through the above structural design, the handheld early smoldering detector provided in this embodiment has the following technical effects:

[0055] The instrument is equipped with a handle 2 on the outside, which allows you to hold the detector and quickly go to the location where there is a fire alarm or the location that needs to be monitored to conduct smoldering detection.

[0056] The instrument is equipped with a telescopic sampling tube 9 on the outside, which can monitor positions at different distances;

[0057] The instrument is equipped with an air intake pump 12, which can actively collect ambient gases and make rapid judgments on the situation on site.

[0058] The instrument's internal detection terminal is equipped with multiple gas sensors 15, which can detect the concentration of particulate matter and gases such as CO and VOCs generated in the early stage of smoldering in the surrounding environment; compare the concentration data with preset data to determine the probability of smoldering, obtain accurate information, and reduce the occurrence of misjudgments due to single monitoring data.

[0059] The lower side of the outer casing 1 has a small hole 1.1 for detecting the discharge of gas from the cavity.

[0060] The top of the telescopic sampling tube 9 is equipped with a filter screen 9.1, which is used to filter hair particles in the gas collected from the surrounding environment, improve detection accuracy, and prevent blockage inside the detector.

[0061] The bottom end of the telescopic sampling tube 9 is connected to the outer casing 1 via a locking nut 10.

[0062] The housing 1 has an internal mounting plate 13 on one side, on which a main board 14 and a battery pack 17 are mounted. The battery pack 17 is electrically connected to the main board 14. The battery pack 17 is used to power the electronic components on the detector.

[0063] The bottom of the outer casing 1 is equipped with a charging socket 3 and a charging indicator light 4, which are electrically connected to the mainboard 14. The charging socket 3 is connected to a municipal power supply via a charging cable to power the battery pack 17.

[0064] The front of the outer casing 1 is equipped with a power switch 5 and a power indicator light 6, which are electrically connected to the main board 14. The power switch 5 is used to turn the detector on and off, and the power indicator light 6 is used to indicate the on and off status of the detector.

[0065] The outer casing 1 has a fire alarm light 7 mounted on its front side, and a sound alarm 16 mounted on the main board 14. The fire alarm light 7 and the sound alarm 16 are electrically connected to the main board 14. The fire alarm light 7 is available in yellow and red.

[0066] The fire alarm light 7 and the sound alarm 16 are 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 fire alarm light 7 and the sound alarm 16 are activated to announce the fire.

[0067] The top surface of the outer casing 1 is equipped with a 4G antenna 8, which is electrically connected to the motherboard 14. The 4G antenna 8 is used for data transmission with an external platform. It transmits signals to the motherboard 14 via a cable, or the motherboard 14 transmits signals to the 4G antenna 8 via a cable and then sends the signals to the mobile terminal.

[0068] The outer casing 1 is provided with an air intake connector 11, which is connected to the outer casing 1 and the air intake pump 12.

[0069] The handle 2 has anti-slip texture.

[0070] like Figure 5 , Figure 6 As shown, in one embodiment, the telescopic sampling tube 9 includes a plurality of concentrically arranged and relatively sliding telescopic sections 21, the number of which is at least three, and a limiting component is provided between adjacent telescopic sections 21. The limiting component includes:

[0071] Threaded area 22 is provided at the end of each expansion joint 21;

[0072] Screw sleeve 23 is fitted on the outside of expansion joint 21 and connected to threaded area 22;

[0073] Arc-shaped groove 24 is provided on the side wall of threaded sleeve 23;

[0074] Arc-shaped limiting piece 25 is slidably connected within arc-shaped groove 24;

[0075] The slide rod 26 is connected to the outside of the arc-shaped limiting piece 25 and extends through the arc-shaped sliding groove 24 to the outside of the screw sleeve 23. A spring is sleeved on the slide rod 26, and the two ends of the spring are respectively connected to the arc-shaped limiting piece 25 and the arc-shaped sliding groove 24.

[0076] Pressure block 27 is connected to the extension end of slide rod 26;

[0077] Annular slots 28, multiple annular slots 28 are evenly arranged on the outer wall of the expansion joint 21.

[0078] The working principle and beneficial effects of the above technical solution are as follows:

[0079] When the telescopic sampling tube 9 is in the retracted state, multiple telescopic joints 21 are sleeved together. At this time, the threaded sleeve 23 is fully screwed onto the threaded area 22 of the telescopic joint 21, and the arc-shaped limiting piece 25 is pressed into the arc-shaped groove 24 by the outer wall of the telescopic joint 21. The multiple telescopic joints 21 can slide relative to each other. When it is necessary to adjust the telescopic sampling tube 9 to extend it, one or more telescopic joints 21 are slid out. After sliding to the preset position, the threaded sleeve 23 is rotated, and the part of the threaded sleeve 23 with the arc-shaped groove 24 extends out of the telescopic joint 21. The arc-shaped limiting piece 25 is no longer pressed by the outer wall of the telescopic joint 21 and quickly pops out inward under the action of the spring, engaging with the annular groove 28 on the inner telescopic joint 21, thereby limiting and locking the inner telescopic joint 21. This effectively realizes the adjustment of the length of the telescopic sampling tube 9, which is convenient for detection at different positions. After the test is completed, when the telescopic sampling tube 9 needs to be retracted and reset, pull the pressure block 27 outward to separate the arc-shaped limiting piece 25 from the annular groove 28, and rotate the threaded sleeve 23 in the opposite direction to reset it onto the threaded area 22, and then slide the telescopic joint 21 back to its original position.

[0080] Multiple annular slots 28 are provided on the telescopic joint 21, so that the telescopic joint 21 can be locked at any length without fully unfolding or retracting, and the adjustable range is wider.

[0081] When the telescopic sampling tube 9 is in the retracted state, the screw sleeve 23 can be rotated to lock the telescopic joint 21, which can prevent the telescopic sampling tube 9 from unfolding on its own during carrying.
