Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to a fire protection smoke exhaust debugging control device. Background Art

[0002] In the field of fire response, the effectiveness of the smoke exhaust system is directly related to personnel safety and rescue results. In the event of a fire, the thick smoke produced by the burning of decoration materials often contains a large amount of toxic substances, which can easily cause poisoning or even suffocation. In order to reduce this risk, fire smoke exhaust systems are generally installed in buildings, aiming to exhaust the toxic smoke to the outside in a timely manner through mechanical smoke exhaust, thereby minimizing the inhalation of toxic smoke by indoor personnel. However, the installation and commissioning of the smoke exhaust system is also an important link, which is directly related to the working effect of the smoke exhaust system.

[0003] Chinese patent CN213022330 U discloses a new type of debugging device for fire smoke exhaust system. When the two spacers of the device are against the air duct, if the inner diameter of the air duct is larger than the curvature of the bottom plate, there is only line contact between the spacers and the inner wall of the air duct. In this case, when the air volume increases, the main box may rotate around the two telescopic rods, causing the angle of the main box to deviate, thereby affecting the detection effect. Only when the inner diameter of the air duct is completely consistent with the curvature of the bottom plate can surface contact be achieved to provide sufficient friction to maintain stability. This strict requirement on the inner diameter of the air duct limits the wide applicability of the debugging device. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. The utility model is further described in combination with the drawings and embodiments:

[0019] like Figure 1-Figure 2 As shown, a fire smoke exhaust debugging control device includes a main body box 1, and the main body box has at least three groups of support mechanisms 3 in a circular array. The support mechanism includes an outer sleeve 31, and a support rod 32 is slidably fitted in the outer sleeve. A rubber arc pad 33 is provided on the top of the support rod. A flexible spring 34 is provided between the rubber arc pad and the outer sleeve, and the flexible spring drives the rubber arc pad away from the outer sleeve. This structural design enables the device to adapt to air ducts of different sizes. Through the elasticity of the flexible spring, the rubber arc pad can fit closely to the inner wall of the air duct to provide stable support.

[0020] In at least one embodiment, a telescopic sleeve is provided between the main body box and the rubber arc pad. The design of the telescopic sleeve further enhances the adaptability and stability of the device, and enables the rubber arc pad to more flexibly adapt to changes in the shape of the air duct.

[0021] Specifically, the telescopic sleeve includes an outer sleeve 37, an inner guide rod 38 and a tightening knob 39. The main body box is provided with a first hinge seat 36, on which the outer sleeve is rotatably connected, and the inner guide rod is slidably fitted in the outer sleeve. The outer sleeve is threadedly connected with a tightening knob, and the tightening knob can make the inner guide rod move along the outer sleeve and be positioned at a place on the outer sleeve. The end of the inner guide rod is rotatably connected to the second hinge seat 35, and the second hinge seat is fixedly connected to the bottom of the rubber arc pad. By adjusting the tightening knob, the position of the inner guide rod can be accurately controlled, thereby achieving fine adjustment of the position and angle of the rubber arc pad. This structural design improves the adjustment accuracy and use flexibility of the equipment.

[0022] The scheme is refined. The first hinge seat is provided with a first rotating shaft 310, on which an outer sleeve is rotatably connected; the second hinge seat is provided with a second rotating shaft 311, on which an inner guide rod is rotatably connected. The design of the first rotating shaft and the second rotating shaft allows the outer sleeve and the inner guide rod to rotate freely within a certain range. This design increases the flexibility of the device during installation and enables the device to adapt to more complex environments.

[0023] In at least one embodiment, a protective cover 2 is provided in the middle of the main box, a mounting hole is formed in the middle of the protective cover, a through net 21 is provided in the mounting hole, and a wind speed sensor 23 and an air volume sensor 24 are provided on the through net. The design of the protective cover can protect the electronic components inside the main box from dust and debris, and at the same time, the through net in the mounting hole ensures that the wind speed sensor and the air volume sensor can accurately measure the wind speed and air volume in the air duct.

[0024] Furthermore, the protective cover is provided with an indicator light 22. The indicator light can intuitively display the working status of the device, so that the user can quickly understand the operating status of the device.

[0025] Furthermore, the protective cover is provided with a speaker and a wireless module. The speaker can sound an alarm when the equipment fails or an abnormal situation occurs, and promptly remind the operator; the wireless module realizes the remote monitoring and control function of the equipment, and improves the intelligence level of the equipment.

[0026] Furthermore, the speaker, the wireless module, the wind speed sensor 23 and the wind volume sensor 24 are connected to a control board.

[0027] Working mode, check whether the equipment is intact, especially whether the rubber arc pad 33, flexible spring 34, support rod 32 and other components are functioning properly. Make sure that all electronic components (such as wind speed sensor 23, air volume sensor 24, speaker, wireless module, etc.) are properly connected and in working condition.

[0028] Squeeze the rubber arc pad 33 toward the middle, which will retract the flexible spring 34 and drive the support rod 32 to move toward the main box 1. Continue squeezing until the distance between the rubber arc pad 33 and the center of the main box 1 is less than the inner diameter of the target air duct. Carefully place the prepared equipment inside the air duct. Loosen the rubber arc pad 33, allowing the flexible spring 34 to release energy and push the rubber arc pad 33 to expand outward until it contacts the inner wall of the air duct. If the contact between the rubber arc pad 33 and the inner wall of the air duct does not completely match, use a telescopic sleeve (including an outer sleeve 37 and an inner guide rod 38) to adjust it. Rotate the tightening knob 39 to move the inner guide rod 38 along the outer sleeve 37, thereby achieving appropriate deformation of the rubber arc pad 33 to ensure its full contact and stable support with the inner wall of the air duct. Ensure that the through net 21 is not blocked so that the wind speed sensor 23 and the air volume sensor 24 can accurately measure.

[0029] Turn on the device and monitor the real-time data of wind speed and air volume through the control panel. According to the status of the indicator light 22 or the information on the control panel, determine whether the smoke exhaust system is operating normally. If there is an abnormality in the smoke exhaust system, the speaker on the device will sound an alarm and send an alarm message through the wireless module. The operator should respond immediately and perform troubleshooting or adjust the smoke exhaust system settings according to the information provided by the control panel. When the smoke exhaust commissioning is completed or the position needs to be changed, repeat step 2 to shrink the rubber arc pad 33, and then remove the device from the air duct. Perform regular maintenance and care on the equipment to ensure the normal operation of all components, especially sensors and springs.
