Description

Technical Field

[0001] This utility model belongs to the field of multi-sensor fusion technology, specifically relating to a warehouse fire alarm device based on multi-sensor fusion. Background Technology

[0002] Multi-sensor fusion technology refers to the comprehensive processing of data collected by multiple external sensors to obtain more comprehensive and accurate information. This technology can acquire a large amount of data in the shortest time, realize resource sharing among multiple sensors, and thus improve the reliability of the system.

[0003] Existing warehouse fire alarm devices are equipped with single smoke and dust sensors and lack the ability to integrate multiple types of sensors. This makes it difficult to coordinate the monitoring of risk indicators such as temperature, humidity, and combustible gases, resulting in limited functionality and application scenarios. Therefore, a warehouse fire alarm device based on multi-sensor fusion is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a warehouse fire alarm device based on multi-sensor fusion to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a warehouse fire alarm device based on multi-sensor fusion, comprising a mounting base, six mounting bolts fixedly connected inside the mounting base, an annular outer shell fixedly connected to the top of the mounting base, several detection ports opened inside the annular outer shell, an interception net covered on the surface of the annular outer shell, a control board fixedly connected to the top of the annular outer shell, six sealing holes opened inside the control board, a controller fixedly connected to the bottom of the control board, an alarm fixedly connected to the top of the control board, and an adjusting column fixedly connected inside the annular outer shell, the adjusting column having an adjustment mechanism inside. The adjusting column has an adjusting screw hole ring slidably connected to its inner wall. A threaded screw rod is threadedly connected to the inner wall of the adjusting screw hole ring. A drive motor is fixedly connected to the top of the threaded screw rod. Six guide grooves are formed on the surface of the adjusting column. Guide rods are slidably connected to the interior of each of the six guide grooves. Mounting platforms are fixedly connected to the other ends of each of the six guide rods. Mounting grooves are formed on the tops of each of the six mounting platforms. Two springs are fixedly connected to the tops of each of the six mounting platforms. Two telescopic connecting rods are fixedly connected to the tops of each of the six mounting platforms. Elastic pressure rings are fixedly connected to the tops of each spring. Sealing rings are fixedly connected to the tops of each elastic pressure ring.

[0006] By setting up the above structure, several detection ports are opened on the surface of the annular shell in multiple directions, forming a multi-directional monitoring and sensing channel. This can minimize the blind spots of traditional single-point detection devices. The interception net installed outside the detection ports can prevent dust particles and other debris from entering the device, while reducing maintenance frequency. The drive motor can drive the threaded screw to rotate, and with the guide rod, the mounting platform can be automatically raised and lowered, which is convenient for firefighters to install, replace or repair different types of external sensors. Then, the spring and telescopic linkage, together with the elastic pressure ring, can fix the external sensor and form a sealed environment with the sealing ring to prevent moisture and dust from entering the device and causing interference. Compared with traditional devices, this device can expand the monitoring indicators, reduce detection blind spots, shorten sensor replacement time, and is suitable for multi-dimensional fire monitoring.

[0007] As a preferred embodiment, the interception net is located outside the detection port, and the adjustment column is fixedly connected to the control plate.

[0008] As a preferred embodiment, the threaded screw rotates inside the adjusting column, and the bottom of the drive motor is fixedly connected to the top of the control board.

[0009] As a preferred embodiment, the four guide grooves are respectively connected to the adjustment groove, and one end of each of the six guide rods is fixedly connected to the surface of the adjustment screw hole ring.

[0010] As a preferred embodiment, the spring is sleeved on the surface of the telescopic link, and the sealing ring slides on the inner wall of the sealing hole.

[0011] By setting up adjustment grooves, adjustment screw hole rings, guide grooves, and guide rods, the relative limiting and guiding of the adjustment screw hole rings and guide rods can play a precise limiting and guiding role when the mounting platform is raised and lowered, effectively preventing the mounting platform from shaking or tilting, ensuring its smooth raising and lowering, and thus improving the stability of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by setting up detection ports, has multiple detection ports distributed in multiple directions on the surface of the annular outer shell, forming a multi-directional monitoring and sensing channel. This minimizes the blind spots of traditional single-point detection devices.

Compared with traditional devices, this device can expand the monitoring indicators, reduce detection blind spots, shorten sensor replacement time, and is suitable for multi-dimensional fire monitoring.

[0027] Working principle and usage process of this utility model:

[0028] This warehouse fire alarm device based on multi-sensor fusion is fixed to a suitable location in the warehouse by mounting base 1 and mounting bolts 2. The detection port 4 on the annular outer shell 3 is used by the internal sensors to sense the warehouse situation. The interception net 5 prevents debris from entering. When it is necessary to add multiple sensors to enrich the monitoring of the warehouse situation, the drive motor 14 is started, which drives the threaded screw 13 to rotate, causing the adjusting screw ring 12 to move upward along the threaded screw 13 in the adjusting groove 11. Simultaneously, the guide rod 16 slides in the guide groove 15, and the mounting platform 17 and sealing ring 22 rise. When the mounting groove on the mounting platform 17... When 18 rises to the outside of the device, the elastic pressure ring 21 is pulled upward to drive the spring 19 and the telescopic connecting rod 20 to extend and retract. Then, the external sensor with a specific function is placed into the mounting slot 18 on the mounting platform 17 to complete the installation. Afterward, under the elastic force of the spring 19, the spring 19 will drive the elastic pressure ring 21 to reset and fix the external sensor. After multiple external sensors with different functions are installed, the drive motor 14 is started to drive the mounting platform 17 and the external sensors installed on the mounting platform 17 to reset, thus completing the installation of multiple external sensors. Similarly, replacement and maintenance can also be performed.

[0029] During operation, multiple external sensors inside the device will simultaneously collect various data and transmit them to the controller 8 for processing. When a relevant abnormal signal is detected, the controller 8 will control the alarm 9 to issue an alarm, reminding warehouse fire personnel to handle the situation in a timely manner, thereby realizing the multi-sensor fusion monitoring and alarm function.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
