Description

Technical Field

[0001] This utility model relates to the field of fire safety equipment technology, specifically to a special base for a fire alarm detector in a generator pit with a protective structure. Background Technology

[0002] In industrial production environments, especially in wind tunnels or unit pits where welding and cutting operations are involved, a large amount of dust and smoke are generated during the operation. These pollutants can easily adhere to the surface of fire alarm detectors or enter their interiors, leading to decreased detector sensitivity, shortened detector lifespan, and even false alarms or missed alarms, seriously threatening the safety of industrial production.

[0003] Traditional fire alarm detector base designs often only consider the installation and fixing functions of the detector, lacking protective measures for special environments. When it is necessary to protect the detector, workers usually need to disassemble or cover the protective cover, which is not only cumbersome and inefficient, but also makes it difficult to guarantee the sealing and stability of the protective cover, and cannot effectively prevent the intrusion of dust and smoke.

[0004] Therefore, existing detector mounting bases have issues with detector protection, operational portability, and structural stability. Utility Model Content

[0005] The purpose of this utility model is to provide a special base for fire alarm detectors in the pit of a unit with a protective structure, addressing the problems of detector protection, operational portability and structural stability of existing detector mounting bases.

[0006] The technical solution of this utility model is as follows:

[0007] A dedicated base for a fire alarm detector in a generator pit with a protective structure includes a mounting base, a shielding cloth, and a hinge plate. The mounting base has a first groove and an annular groove. A fixing ring is provided between the first groove and the annular groove. Two corresponding fixing strips are provided on the fixing ring. A limit groove is provided on the side of the two fixing strips that are far apart from each other. A limit block is slidably provided in the limit groove. The two limit blocks are fixedly connected to the hinge plate. The two hinge plates are rotatably connected to one side of two semi-annular frames. A magnet is provided at the center of the lower end of the semi-annular frame. The upper end of the semi-annular frame is connected to the shielding cloth. The other end of the shielding cloth is connected to the lower end of the first groove.

[0008] Two corresponding electric reels are installed on the outside of the mounting base. The electric reels drive the semi-circular frame to retract or extend.

[0009] With the above structure, the electric cable reel drives the shielding cloth and the semi-circular frame to move downwards via the connecting line, thereby moving the limiting block to the bottom of the limiting groove. The semi-circular frame hinges and flips along the hinge plate, causing the two magnets to attract each other and the two shielding cloths to merge into a protective cover, thereby protecting the internal detection components. When it is necessary to retract the cable, the electric cable reel is turned on to tighten the cable on the semi-circular frame, thereby resetting the semi-circular frame in the first groove.

[0010] Furthermore, two corresponding wiring slots are provided through the outer side of the mounting base, and a rotating wheel is rotatably installed in the wiring slot. The wiring slot is interconnected with the first groove. After the connecting wire of the electric reel passes through the wiring slot, it goes around the outer wall of the rotating wheel, passes through the first groove and the shielding cloth, and then connects to the upper end of the semi-circular frame.

[0011] Furthermore, the electric reel is positioned corresponding to the wiring slot.

[0012] Furthermore, the annular slot is equipped with a snap-fit ​​connection with a retaining ring, and a detector is fixedly connected below the retaining ring. Two conductive posts are fixedly connected to the upper end of the detector.

[0013] Furthermore, an electrical mounting base is fixedly provided on the upper surface of the inner wall of the mounting base, and an electrical mounting base is rotatably connected to a wire fixing clamp, and an electrical wire connecting groove is provided through the upper surface of the mounting base.

[0014] Furthermore, the upper end of the conductive post is correspondingly and closely fitted to the lower end of the wire fixing clamp.

[0015] Through the above structure, the two wire fixing clamps conduct electricity to the two conductive posts on the detector.

[0016] Furthermore, a first mounting groove is provided through the upper surface of the mounting base, and a dustproof mesh is provided on the inner wall of the first mounting groove.

[0017] Through the above structure, the dustproof net can provide dust protection and heat dissipation for the detectors installed later during operation.

[0018] Furthermore, a remote control trigger button is provided on the outside of the mounting base, and the remote control trigger button is electrically connected to the electric reel.

[0019] The above structure allows the remote trigger button to control the opening or closing of the electric reel.

[0020] Furthermore, the diameter of the first groove is larger than the diameter of the annular groove.

[0021] Furthermore, the shielding cloth is folded and disposed inside the wiring groove, and the length of the shielding cloth is much greater than the distance that the limiting block can slide in the limiting groove.

[0022] Compared with existing technologies, the beneficial effects of this utility model are:

[0023] When there is a lot of welding smoke inside the wind tunnel, by turning on two electric cable reels, the connecting wires on the electric cable reels move the semi-ring frame and the hinge plate downwards synchronously under the limit of the rotating wheel. When the lower end of the limit block on the hinge plate and the lower end of the inner wall of the fixing strip are in contact with each other, the two semi-ring frames hinge and flip around the two hinge plates, so that the two magnets attract each other and the two shielding cloths merge to form a protective cover, thereby protecting the internal detection components. When it is necessary to retract the work, the electric cable reel is turned on to tighten the cable on the semi-ring frame, so that the semi-ring frame is reset in the first groove.

[0031] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0032] Please see Figure 1-5 A dedicated base for a fire alarm detector in a generator pit with a protective structure includes a mounting base 1; it also includes a shielding cloth 302 and a hinge plate 4. The lower end of the mounting base 1 has a first groove 106 and an annular slot 107. A fixed ring 108 is formed by the first groove 106 and the annular slot 107 approaching each other. Two fixing strips 402 are fixedly connected to the fixed ring 108. A limiting groove 403 is formed at the far end of the two fixing strips 402. A limiting block 401 is slidably arranged in the limiting groove 403. A hinge plate 4 is fixedly connected at the far end of the two limiting blocks 401. Two semi-annular frames 303 are rotatably arranged on the hinge plate 4. A magnet 304 is located at the center of the lower end of each semi-annular frame 303. The upper end of each semi-annular frame 303 is connected to the shielding cloth 302, and the other end of the shielding cloth 302 is connected to the lower end of the first groove 106. Two electric cable reels 301 are installed on both sides of the arc-shaped outer wall of seat 1. The semi-ring frame 303 is driven by the electric cable reels 301. When there is a lot of smoke during welding work in the wind tunnel, the two electric cable reels 301 are turned on. The connecting wires on the electric cable reels 301 are limited by the rotating wheel 3, causing the semi-ring frame 303 and the hinge plate 4 to move downward synchronously. When the lower end of the limiting block 401 on the hinge plate 4 and the lower end of the inner wall of the fixing strip 402 are in contact with each other, the two semi-ring frames 303 are hinged and flipped around the two hinge plates 4, so that the two magnets 304 attract each other and the two shielding cloths 302 merge to form a protective cover, thereby protecting the internal detection components. When it is necessary to retract the work, the electric cable reels 301 are turned on to tighten the cable on the semi-ring frame 303, so that the semi-ring frame 303 is reset in the first groove 106.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the arc-shaped outer wall of the mounting base 1 is provided with a wiring groove 109. The inner wall of the wiring groove 109 is rotatably provided with rotating wheels 3 at both ends. The wiring groove 109 and the first groove 106 are interconnected. The connecting wire of the electric reel 301 passes through the wiring groove 109 and then passes down the outer wall of the rotating wheel 3, through the first groove 106 and the shielding cloth 302, and is connected to the upper end of the semi-circular frame 303. The upper and lower ends of the mounting base 1 are provided with a first mounting groove 101. The inner wall of the first mounting groove 101 is provided with a dustproof net 102. The dustproof net 102 can provide dust protection and heat dissipation for the detector 201 installed later during operation. The front end of the mounting base 1 is provided with a remote control trigger button 5. The remote control trigger button 5 is electrically connected to the electric reel 301.

[0034] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, a snap ring 2 is snapped into the annular slot 107. A detector 201 is fixedly connected to the lower end of the snap ring 2. Two conductive posts 202 are fixedly connected to the upper end of the detector 201. An electrical mounting base 104 is fixedly connected to the lower end of the inner wall of the mounting base 1. A wire fixing clamp 105 is rotatably installed at the lower end of the electrical mounting base 104. Wire connecting grooves 103 are opened through the upper and lower ends of the mounting base 1. The wires passing through the wire connecting grooves 103 can be threaded and fixed by the electrical mounting base 104 and the wire fixing clamp 105. The upper ends of the conductive posts 202 and the lower ends of the wire fixing clamps 105 correspond one-to-one and fit together. The two wire fixing clamps 105 conduct electricity to the two conductive posts 202 on the detector 201.

[0035] Working principle: First, the mounting base 1 is installed onto the inner wall of the wind tunnel using double-sided tape or a threaded installation structure. Then, the wire is passed through the wire connecting groove 103, and the electrical mounting base 104 is placed in it. The wire fixing clamp 105 is then used for threaded installation and fixation. Next, the retaining ring 2 on the detector 201 is inserted into the annular retaining groove 107 for snap-fit ​​fixation, so that the two conductive posts 202 and the two corresponding wire fixing clamps 105 make contact with each other and conduct electricity, causing the retaining ring 2 to work. When there is a lot of smoke during welding work in the wind tunnel, the two electric reels 301 are activated by remote control or manual pressing of the remote control trigger button 5, and the electric reels are activated. The connecting wire on the device 301 causes the semi-ring frame 303 and the hinge plate 4 to move downward synchronously under the limit of the rotating wheel 3. When the lower end of the limiting block 401 on the hinge plate 4 and the lower end of the inner wall of the fixing strip 402 are in contact with each other, the two semi-ring frames 303 hinge and flip around the two hinge plates 4, so that the two magnets 304 attract each other and the two shielding cloths 302 merge to form a protective cover, thereby protecting the internal detector 201. When it is necessary to retract the work, the electric reel 301 is turned on to tighten the cable on the semi-ring frame 303, so that the semi-ring frame 303 is reset in the first groove 106.

[0036] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
