[0002] The fire safety of tobacco warehouse is the top priority of industry management. The stored tobacco leaves and cigarette products are highly flammable. The fire warning device installed in the tobacco warehouse can monitor in real time, capture the fire point in the first time, inform the security personnel, and jointly deal with the fire emergency with other devices, which greatly reduces the loss of tobacco warehouse in case of fire. However, the existing fire warning device lacks the combination of multi-source sensor data, and only relies on single data such as smoke concentration and temperature for analysis, which greatly increases the false alarm rate, causes unnecessary fire treatment, and causes damage to the goods in the tobacco warehouse.

[0003] The tobacco warehouse stores a large amount of goods, and the forklift operation is frequent, which is very easy to cause dust to fly. After the dust enters the detection device, it will affect the collection of fire data by the fire warning device, reduce the detection accuracy, and cause misjudgment of the fire. A large amount of dust accumulates in the filter screen of the smoke concentration detection device, blocks the air suction holes, reduces the gas absorption amount, prolongs the fire detection time, and causes the fire warning device to be unable to perform fire emergency treatment in the first time, resulting in significant loss. SUMMARY

[0004] In order to overcome the problem that the dust flying in the tobacco warehouse enters the fire warning device and affects the accuracy of the collection of fire data, causes misjudgment of the fire, and the dust blocks the air suction holes of the smoke concentration detection device, reduces the gas absorption amount, prolongs the fire judgment time, and cannot perform fire emergency treatment in the first time, the present application provides a special fire warning device for tobacco warehouse.

DETAILED DESCRIPTION

[0020] The application will be further described below in conjunction with the drawings and examples.

[0021] Example 1, a tobacco warehouse special fire warning device, as shown in​Figures 1-6 As shown, it includes a main housing 1, a filter 5, a base 6, a camera 7, a collection box 3, a cleaning component, and a collection component. Several air inlets 1001 are provided inside the main housing 1. A smoke concentration detection component 4 is installed inside the main housing 1. The filter 5 is fixedly connected to the inside of the main housing 1, and the filter 5 covers all the air inlets 1001. The base 6 is fixedly connected to the middle of the inside of the main housing 1. A camera 7 is installed at the lower part of the base 6. Four circumferentially arranged fixing blocks 2 are connected to the lower part of the main housing 1. A collection box 3 is installed on each of the four fixing blocks 2, and the collection box 3 can be disassembled at any time to facilitate the removal of the collected dust. A cleaning component is installed inside the main housing 1. A collection component is fixedly connected to the upper part of the collection box 3.

[0022] The collection component includes a slider 201 and a first airbag 204; four sliders 201 arranged in a circumferential array are slidably connected to the inside of the receiving box 3; an annular fixing plate 202 is fixedly connected to the upper part of the four sliders 201; a first airbag 204 is fixedly connected to the inner side of the annular fixing plate 202, and the first airbag 204 is fixedly connected to the inner side of the receiving box 3. When the first airbag 204 is filled with gas, it can seal the upper part of the receiving box 3, ensuring that the air blown out by the air outlet 105 will not blow away the dust contained in the receiving box 3, thus avoiding secondary dust re-entrainment.

[0023] The receiving box 3 has four ventilation openings 3001 on its inner side, and all ventilation openings 3001 face the camera 7. The ventilation openings 3001 can guide the air blown out of the air outlet 105 to the surface of the camera 7 to clean the dust on the surface of the camera 7 and prevent dust from accumulating on the surface of the camera 7 and affecting the visual positioning.

[0024] The upper part of the camera 7 is equipped with four sets of moving components 7001 arranged in a circumferential array. The moving components 7001 enable the camera 7 to move up and down, thereby expanding the monitoring range of the camera 7 and coordinating with other surveillance cameras to ensure that there are no blind spots in the monitoring. The camera 7 is relatively large, but the airflow from the vent 3001 is fixed and cannot clean the dust of the camera 7 completely. By moving the camera 7 up and down through all the moving components 7001, the airflow can blow away the dust on the entire surface of the camera 7, ensuring that there are no blind spots in the cleaning.

[0025] The collection component also includes a connecting block 205 and a second airbag 206; four connecting blocks 205 arranged in a circumferential array are fixedly connected to the lower part of the base 6; and several second airbags 206 are arranged between each two adjacent connecting blocks 205.

[0026] When each second airbag 206 is in a fully inflated state, adjacent second airbags 206 are tightly connected, and the innermost and outermost second airbags 206 are connected to the receiving box 3 and the base 6. All second airbags 206 are connected and in close contact with the receiving box 3 and the base 6. This can seal the gap between the receiving box 3 and the base 6, and when the first airbag 204 is fully inflated, the air blown out by the air duct 105 can only be discharged from the vent 3001, and the air is directly directed to the surface of the camera 7.

[0027] During normal operation, this invention requires smoke concentration detection and real-time video monitoring of the tobacco warehouse to ensure the absence of a fire. In this operating state, neither the first airbag 204 nor the second airbag 206 is fully inflated, and the receiving box 3 is open. A certain amount of space is left between adjacent second airbags 206 to allow a large amount of air to pass through. The smoke concentration detection component 4 draws a certain amount of air from the warehouse, and the air passes through the gap between adjacent second airbags 206 and the ventilation opening 3001 before entering the air inlet 1001. Because all air inlets 1001 are covered by filters 5, the smoke concentration... All air is filtered by filter 5. The size of the pores in filter 5 separates smoke particles from dust particles. Smoke particles enter the smoke concentration detection component 4 for analysis to obtain monitoring data. Dust particles that are too large are intercepted on filter 5 to prevent them from entering the detection device and affecting the accuracy of the detection results. Camera 7 is in a real-time detection state. Every once in a while, all moving components 7001 move camera 7 downwards. When moving downwards, the monitoring range of camera 7 can be expanded, and it can work in conjunction with other monitoring cameras to ensure that there are no blind spots in the monitoring.

[0028] Example 2, based on Example 1, such as Figure 7 and Figure 8 As shown, the cleaning assembly includes a moving block 101 and a brush 104; the moving block 101 is slidably connected to the inner side of the main housing 1; two electric push rods 102 are provided inside the main housing 1, the two electric push rods 102 are symmetrically arranged, and both electric push rods 102 are fixedly connected to the upper part of the moving block 101; a rotating plate 103 is provided at the lower part of the moving block 101; several sets of scraping components are fixedly connected to the lower part of the rotating plate 103, and each set of scraping components consists of several brushes 104.

[0029] Each brush 104 is L-shaped. Setting the brush 104 to L-shape increases the contact area between the brush 104 and the filter 5, improves the cleaning strength of the brush 104 on the filter 5, and ensures that dust will not clog the air inlet 1001. Setting it to L-shape also enhances the cleaning effect of the air blown out by the blower 105 on the brush 104.

[0030] The cleaning assembly also includes an air outlet 105; several air outlets 105 are fixedly connected to the lower part of the rotating plate 103, and each air outlet 105 corresponds to a set of scraping components. The air outlet 105 can guide the air blown out by the blowing components provided inside the rotating plate 103 through the brush 104 to the filter screen 5, blow away the dust on the surface of the filter screen 5, and enhance the cleaning of the filter screen 5; and the air blown out from the air outlet 105 passes through the brush 104, and the brush 104 is cleaned by the blowing of the air, thus ensuring the cleaning ability of the brush 104.

[0031] After the smoke concentration detection component 4 completes its detection, a large amount of dust particles remain on the surface of the filter screen 5. If these particles are not cleaned in time, they will clog the air inlet 1001, affecting the results of the next smoke concentration detection. Therefore, the electric push rod 102 pushes the moving block 101 downward, while the rotating plate 103 rotates, allowing the brush 104 to clean the surface of the filter screen 5. The L-shaped brush 104 increases the contact area between the brush 104 and the filter screen 5, improving the cleaning strength of the brush 104 and ensuring that the dust does not clog the air inlet 1001, thus sweeping the dust off the filter screen 5. The blower assembly inside block 101 blows air out through the air outlet 105. The air is guided by the brush 104 to the surface of the filter screen 5. With the help of the air, the brush 104 can more easily sweep away the dust. The air blown out by the air outlet 105 also acts directly on the brush 104, which can achieve self-cleaning of the brush 104 under the action of the air, ensuring that the brush 104 will not stick to the dust. After cleaning, all the dust falls into the collection box 3 for storage. The staff only needs to pry open the fixing block 2 every once in a while, take out the collection box 3 to pour out the powder, and then put the collection box 3 back in its original position and lock it in place with the fixing block 2.

[0032] Example 3, based on Examples 1 and 2, such as Figure 9 and Figure 10 As shown, the collection assembly also includes a first magnet 203 and a second magnet 207; the first magnet 203 is fixedly connected to the outer side of the receiving box 3; the second magnet 207 is fixedly connected to the outer side of the annular fixing plate 202; the first magnet 203 and the second magnet 207 are set so that the annular fixing plate 202 is in close contact with the receiving box 3, ensuring that the wind will not enter the receiving box 3 and cause the dust to fly again.

[0033] Because camera 7 is located at the edge of the air intake, its surface is also a major area for dust accumulation. Unclear monitoring by camera 7 can affect the assessment of whether there is a fire in the tobacco warehouse, so cleaning of camera 7 is necessary. Inflating the first airbag 204, and with the assistance of the slider 201, causes the annular fixing plate 202 to adhere tightly to the receiving box 3. Furthermore, the magnetic attraction between the first magnet 203 and the second magnet 207 allows the first airbag 204 to seal the inside of the receiving box 3, ensuring that the air blown from the exhaust duct 105 does not disperse the dust inside the receiving box 3, thus preventing secondary dust re-entrainment. Simultaneously, the second airbag 206 is inflated. When the second airbags 206 are fully inflated, they will press against each other without leaving any gaps. This seals the ventilation path between the second airbags 206, forcing the air blown out of the air outlet 105 to be discharged only through the vent 3001. Since the vents 3001 are all facing the surface of the camera 7, the dust on the surface of the camera 7 is blown away by the wind. When the wind blows on the surface of the camera 7, all moving components 7001 move the camera 7 up and down, allowing the wind to blow away the dust on the entire surface of the camera 7, ensuring that the camera 7 can monitor normally.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
