Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, specifically to an intelligent fire extinguisher status sensing device. Background Technology

[0002] With the advancement of intelligent fire protection management, the industry is gradually adopting cameras to monitor the status of fire extinguisher safety pins in real time. Combined with image recognition technology, these cameras can identify whether the safety pins have fallen off, thus replacing traditional manual inspections and improving management efficiency.

[0003] Most mainstream smart fire extinguishers currently use a design that integrates the camera with a dedicated one-piece housing. This means that the camera, power supply module, data transmission module, etc., are all fixed inside a customized housing, and then connected to the fire extinguisher through the housing as a whole.

[0004] However, this type of intelligent fire extinguisher is not compatible with the large number of traditional fire extinguishers already in use on the market. Traditional fire extinguishers are difficult to upgrade to intelligent monitoring versions, and the entire fire extinguisher needs to be replaced to achieve intelligent transformation, so the compatibility is not high enough. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent fire extinguisher status sensing device, which uses a camera module and matching installation components to monitor the status of the safety pin on the outside of the fire extinguisher. The installation components can provide multiple mounting positions for the camera module and can be quickly installed with traditional fire extinguishers, thereby improving the compatibility between traditional fire extinguishers and monitoring modules.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an intelligent fire extinguisher status sensing device, comprising a fire extinguisher, wherein the fire extinguisher is externally equipped with a camera module capable of monitoring the status of the fire extinguisher safety pin and an installation component for mounting the camera module;

[0007] The mounting assembly includes a clamp fixed to the outer wall of the fire extinguisher. The top of the fire extinguisher is provided with a kit to prevent the clamp from slipping off. A connection structure is installed between the kit and the clamp to provide multiple mounting positions for the camera module and facilitate quick installation of the camera module.

[0008] Preferably, the kit includes a collar that can be fitted onto the outer wall of the top of the fire extinguisher. The bottom of the collar has several connecting pieces integrally formed therein that can fit against the outer wall of the fire extinguisher. The bottom ends of the connecting pieces are fixedly connected to the clamp.

[0009] Preferably, the connecting structure includes a fixing rod, which is arc-shaped and has connecting holes at both ends. The two ends of the fixing rod are fixedly connected to a clamp and a collar, respectively, by screws.

[0010] Preferably, the connection structure further includes a rubber ring embedded in the camera module, and the outer wall of the fixing rod is provided with a plurality of integrally formed protruding rings, with the rubber ring sleeved between adjacent protruding rings on the outer wall of the fixing rod.

[0011] Preferably, the camera module includes a camera and a housing fixed outside the camera. A through groove is provided inside one end of the housing, the through groove passing through the top and bottom of the housing, and the rubber ring is fixed to both ends of the inner wall of the through groove.

[0012] Preferably, the fire extinguisher includes a canister, and a handle, a pressure handle, and a safety pin installed on the top of the canister. The top of the canister is provided with a nozzle that communicates with the inner cavity of the canister, and the camera is installed on the side of the outer casing near the safety pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the separate design of an independent camera module and a universal mounting component, eliminates the need to alter the original structure of traditional fire extinguishers. The camera module can be fixed to the outside of a traditional fire extinguisher using only the mounting component, enabling monitoring of the safety pin's status. The kit within the mounting component, through the combination of a collar and a connecting piece, fits snugly against the top structure of a traditional fire extinguisher. Simultaneously, the connecting structure provides a flexible installation angle for the camera module, improving the adaptability of smart fire extinguishers for retrofitting.

[0015] 2. In this utility model, the fixing rod in the connecting structure is arc-shaped, and its outer wall is integrally formed with several protruding rings. The outer shell of the camera module is fitted onto the fixing rod through a through groove, and the rubber ring on the inner wall of the through groove can be engaged between adjacent protruding rings. When the height of the fire extinguisher is different, the rubber ring can be fixed by selecting protruding rings at different positions, so that the position of the camera module on the fixing rod is different. Because the fixing rod is arc-shaped, the angle of the camera installed at different positions is different, ensuring that the camera can be aligned with the safety pin of the fire extinguisher, and adapting to fire extinguishers of different heights.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution: an intelligent fire extinguisher status sensing device, including a fire extinguisher 1, wherein the fire extinguisher 1 is externally provided with a camera module 2 capable of monitoring the status of the safety pin 104 of the fire extinguisher 1, and an installation component for installing the camera module 2.

[0029] The mounting assembly includes a clamp 3 fixed to the outer wall of the fire extinguisher 1. The top of the fire extinguisher 1 is provided with a kit 5 that can prevent the clamp 3 from slipping off. A connection structure 4 is installed between the kit 5 and the clamp 3 to provide multiple mounting positions for the camera module 2 and facilitate the quick installation of the camera module 201.

[0030] The device uses a traditional fire extinguisher 1 as a carrier, and separates the monitoring component and the installation component. The camera module 2 is used to collect real-time image information of the safety pin 104 of the fire extinguisher 1, and uses image recognition technology to determine whether the safety pin 104 has fallen off. The installation component plays a fixed supporting role, assembling the camera module 2 on the outside of the fire extinguisher 1 without damaging the original structure of the fire extinguisher 1.

[0031] The kit 5 includes a collar 501 that can be fitted onto the top outer wall of the fire extinguisher 1. The bottom of the collar 501 is integrally formed with several connecting pieces 502 that can fit against the outer wall of the fire extinguisher 1. The bottom end of the connecting pieces 502 is fixedly connected to the clamp 3.

[0032] The collar 501 has a ring structure and can be fitted onto the top of the fire extinguisher 1, such as... Figure 1 As shown, it is connected to the clamp 3 via the connecting piece 502. Since the diameter of the collar 501 is smaller than the diameter of the fire extinguisher 1 tank 101, when the clamp 3 tends to slide downward, it can provide an upward pulling force to the clamp 3, preventing the clamp 3 from slipping off, and providing more stable support for the installation of the camera module 2.

[0033] The connecting structure 4 includes a fixing rod 401, which is arc-shaped. Both ends of the fixing rod 401 are provided with connecting holes 402. The two ends of the fixing rod 401 are fixedly connected to the clamp 3 and the collar 501 by screws, respectively.

[0034] like Figure 2 As shown, the fixing rod 401 is an outwardly curved arc rod. One end is directly fixed to the clamp 3 with a screw, and the other end is inserted into the collar 501. The screw is then passed through the outer wall of the collar 501 and screwed into the connecting hole 402 to achieve a stable connection.

[0035] The connecting structure 4 also includes a rubber ring 403 embedded in the camera module 2. The outer wall of the fixing rod 401 is provided with several integrally formed protruding rings 404, and the rubber ring 403 is sleeved between adjacent protruding rings 404 on the outer wall of the fixing rod 401. The inner wall of the rubber ring 403 fits against the outer wall of the fixing rod 401. By fitting the rubber ring 403 between adjacent protruding rings 404 at different positions, the vertical position of the camera module 2 on the fixing rod 401 can be adjusted. Due to the arc shape of the fixing rod 401, the angle of the camera module 2 is different when it is installed in different positions. When the fire extinguisher 1 is high, that is, when the distance between the safety pin 104 and the camera module 2 is large, the camera module 2 can be lowered so that the front end of the camera module 2 captures the image upward along the arc tangent of the fixing rod 401, adapting to the position of the safety pin 104.

[0036] The camera module 2 includes a camera 201 and a housing 202 fixed to the outside of the camera 201. A through groove 203 is provided inside one end of the housing 202. The through groove 203 passes through the top and bottom of the housing 202. The rubber ring 403 is fixed to both ends of the inner wall of the through groove 203.

[0037] The through groove 203 runs through the top and bottom of the outer shell 202, forming an installation channel that is compatible with the fixing rod 401. The outer shell 202 is fitted onto the fixing rod 401 through the through groove 203, realizing quick docking with the connecting structure 4. The rubber rings 403 at both ends of the inner wall of the through groove 203 cooperate with the protruding rings 404 of the fixing rod 401 to fix the outer shell 202 at a specific position on the fixing rod 401.

[0038] The structure of the camera module 2 is the same as that of the prior art. The outer shell 202 integrates auxiliary components such as a battery that powers the camera 201 and a data transmission module, making the camera module 2 an independent functional unit.

[0039] The fire extinguisher 1 includes a canister 101, and a handle 102, a pressure handle 103 and a safety pin 104 installed on the top of the canister 101. The top of the canister 101 is provided with a nozzle 105 that communicates with the inner cavity of the canister 101. The camera 201 is installed on the side of the outer casing 202 near the safety pin 104.

[0040] The camera is directly aimed at the safety pin 104, which can clearly capture image information such as the appearance and position of the safety pin 104. When the safety pin 104 is in the normal insertion state or the detached state, the camera 201 can capture obvious image differences, providing clear image data for the subsequent image recognition algorithm to determine the state of the safety pin 104.

[0041] In use, the fixing rod 401 is fixed to the outer wall of the clamp 3 with screws, and the outer shell 202 is fitted onto the fixing rod 401 through the through groove 203; the kit 5 and the clamp 3 are fitted onto the outer wall of the fire extinguisher 1, and the collar 501 is automatically fitted onto the top of the fire extinguisher 1. According to the position of the safety pin 104, the clamp 3 is rotated so that the camera 201 is in a position where the safety pin 104 can be photographed, and then the clamp 3 is locked.

[0042] Manually pull the outer casing 202 up or down to adjust its height on the fixing rod 401. The rubber ring 403 will engage between the convex ring 404. When the camera 201 can clearly capture the image of the safety pin 104, fix the top of the fixing rod 401. Specifically, insert the top of the fixing rod 401 into the collar 501. The outer wall of the collar 501 has a groove. After the fixing rod 401 is inserted into the groove, screw it into the connecting hole 402 to fix the fixing rod 401 and the collar 501.

[0043] Camera module 2 has a built-in lithium battery. After being powered on, camera 201 enters real-time working mode, continuously acquiring image information of safety pin 104. Simultaneously, the data transmission module within the module, such as the WiFi module, is activated. Camera 201 transmits the acquired image of safety pin 104 to the fire monitoring platform in real time. The backend uses a preset image recognition algorithm to compare the shape and position features of safety pin 104 in the image. Camera module 2 is only responsible for real-time image acquisition and transmission; subsequent image recognition processing and alarm notification are handled by the backend computer, which will not be elaborated further.

[0044] 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.
