Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to an explosion-proof smoke detector. Background Art

[0002] Explosion-proof smoke detectors can detect smoke and fire hazards in time, providing effective safety protection for people. When the smoke concentration on site exceeds the set threshold, the detector will send an alarm signal to the controller to remind people to take corresponding safety measures.

[0003] At present, explosion-proof smoke detectors are suitable for closed spaces such as warehouses, factories, high-rise places, tunnels, underground garages, and places with electrical fire hazards. At present, since the density of smoke is less than that of air, the installation position usually needs to be set at the top of the building. During installation, personnel need to use a stepladder to install and position the detector. During subsequent inspection and maintenance, the stepladder is also needed to disassemble the detector. This installation method makes the on-site operation more cumbersome, and the subsequent inspection and maintenance are inconvenient. Moreover, it is risky for personnel to work at a higher position using a stepladder. In view of the deficiencies in the prior art, the utility model provides an explosion-proof smoke detector to solve the above problems. Utility Model Content

[0006] The detector support belt is loaded with a smoke detector body;

[0007] A clamping wheel is provided on the rotating shaft of the second pulley, and a clamping mechanism for clamping the clamping wheel in position is provided on the detector support seat. The clamping mechanism includes a sleeve fixedly connected to the detector support seat, and a clamping block is movably clamped inside the sleeve. The clamping wheel is clamped between two groups of clamping blocks.

[0008] Preferably, a screw rod is threadedly connected to the sleeve, and the screw rod is rotatably connected to the clamping block.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application provides an explosion-proof smoke detector, which solves the problem that the explosion-proof smoke detectors in the prior art are usually installed at the top of the building. During installation, personnel need to use a stepladder to install and position the detector. During subsequent inspection and maintenance, the detector also needs to be disassembled using the stepladder. This installation method results in cumbersome on-site operations, inconvenient subsequent inspection and maintenance, and there is a risk that personnel have to use a stepladder to work at a high position.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses an explosion-proof smoke detector. Figure 1-4 As shown, it comprises a detector support base 1, on which a first belt pulley 2 and a second belt pulley 3 are rotatably connected, and a detector support belt 4 is sleeved on the first belt pulley 2 and the second belt pulley 3;

[0026] The detector support belt 4 is loaded with a smoke detector body 5;

[0027] A clamping wheel 301 is provided on the rotating shaft of the second pulley 3, and a clamping mechanism for clamping the clamping wheel 301 in position is provided on the detector support seat 1. The clamping mechanism includes a sleeve 6 fixedly connected to the detector support seat 1, and a clamping block 601 is movably clamped inside the sleeve 6. The clamping wheel 301 is clamped between two groups of clamping blocks 601.

[0028] Furthermore, a screw rod 602 is threadedly connected to the sleeve 6, and the screw rod 602 is rotatably connected to the clamping block 601. The arrangement of the screw rod 602 facilitates position adjustment and movement of the clamping block 601, thereby facilitating the clamping of the clamping block 601 to the clamping wheel 301.

[0029] Specifically, a rotating handle 603 is fixedly connected to the screw rod 602 , and the rotating handle 603 makes the screw rod 602 easy to rotate.

[0030] It is particularly disclosed that a connecting rod 604 is fixedly connected between the sleeve 6 and the detector support seat 1 , and the connecting rod 604 is arranged to fix the position of the sleeve 6 .

[0031] Furthermore, a hand wheel 302 is fixedly connected to the rotating shaft of the second pulley 3 , and the hand wheel 302 is arranged to facilitate the rotation of the second pulley 3 .

[0032] Furthermore, a fixing platform 401 is fixedly connected to the detector support belt 4, and a mounting platform 501 is fixedly connected to the smoke detector body 5. The mounting platform 501 and the fixing platform 401 are fixedly connected, and the mounting platform 501 and the fixing platform 401 are fixed by bolts. Therefore, the mounting platform 501 and the fixing platform 401 are easy to disassemble and assemble, thereby making it easy for the smoke detector body 5 to be installed or disassembled on the detector support belt 4.

[0033] Furthermore, a reinforcing rib 402 is fixedly connected between the fixing platform 401 and the detector supporting belt 4 , and the reinforcing rib 402 is provided to provide reinforcement for the fixing platform 401 and the detector supporting belt 4 .

[0034] When installing the smoke detector body 5, the detector support base 1 is directly installed on the target wall, and the hand wheel 302 is subsequently rotated to drive the second pulley 3 and the rotating shaft of the second pulley 3 to rotate, and the second pulley 3 drives the detector support belt 4 and the first pulley 2 to rotate, and the detector support belt 4 then drives the smoke detector body 5 to move, so that the smoke detector body 5 is adjusted to the target height. After adjusting to the target height, the clamping mechanism is used to clamp the clamping wheel 301 to limit the position, so that the second pulley 3, the detector support belt 4 and the smoke detector body 5 are fixed in position;

[0035] When the clamping mechanism is used to clamp and limit the position of the clamping wheel 301 , the screw rod 602 can be directly rotated, and the screw rod 602 pushes the clamping block 601 to move, and finally the clamping wheel 301 can be clamped by two sets of clamping blocks 601 .

[0036] The explosion-proof smoke detector is convenient for adjusting the height of the smoke detector body 5 after installation, and the installer does not need to climb during adjustment. During subsequent inspection and maintenance, the smoke detector body 5 can be quickly raised and lowered, thereby ensuring convenient maintenance of the smoke detector body 5 and the safety of the staff.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
