Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and in particular to a safe air volume adaptive adjustment device. Background Technology

[0002] In many industrial production processes and some special indoor environments, such as chemical workshops and laboratories, it is necessary to promptly exhaust harmful gases or regulate the indoor air environment. Exhaust fans usually operate with a fixed exhaust volume and cannot adaptively adjust the exhaust volume according to changes in actual environmental parameters such as indoor harmful gas concentration, air humidity, and temperature. This may lead to excessive exhaust and energy waste when the concentration of harmful gases is low, and insufficient exhaust volume when the concentration of harmful gases suddenly increases, failing to effectively and promptly exhaust harmful gases, posing a threat to the health of workers and environmental safety. In view of the above reasons, this application proposes a safe exhaust volume adaptive adjustment device. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0035] Example 1

[0036] like Figure 1-4 As shown, the present invention proposes a safety exhaust volume adaptive adjustment device, including a body 1, a servo motor 2 for driving the exhaust, a fan blade 3 for exhaust at the output end of the servo motor 2, a mounting bracket 4 for mounting on the top of the body 1, a gas concentration sensor 5 for detecting the concentration above the mounting bracket 4, the gas concentration sensor 5 can monitor the concentration of indoor gas in real time, its specific model is MQ-135, a single-chip microcomputer 7 for analyzing and processing signals and controlling the servo motor 2 at the bottom of the mounting bracket 4, its specific model is STC89C52, two positioning structures 6 for fixing the gas concentration sensor 5 are provided above the mounting bracket 4, and a protective cover is provided at the end of the body 1 away from the air inlet pipe 9, the protective cover can improve safety, and the protective cover is made of stainless steel;

[0037] The positioning structure 6 includes a mounting base 601 for installation and a pressure plate 607 for positioning. A locking frame 602 for locking is movably provided inside the mounting base 601. A top rod 603 is movably provided on one inner wall of the mounting base 601. A connecting base 604 is movably provided on the outside of the locking frame 602. The connecting base 604 is fixedly connected to one inner wall of the mounting base 601. A spring 605 is fixedly provided on one side of the locking frame 602. The other end of the spring 605 is fixedly connected to the mounting base 601. A connecting frame 606 is fixedly provided on the top of the pressure plate 607. Limiting grooves are provided on both inner walls of the mounting base 601. Limiting strips are fixedly provided on both sides of the connecting frame 606. The limiting strips are movably connected to the limiting grooves. A locking block 608 is fixedly provided on the connecting frame 606. The locking frame 602 includes a locking rod and a locking hook. The sides of the locking hook and the locking block 608 that are close to each other are provided with parallel inclined surfaces. A spring 602 is movably sleeved on the top rod 603.

[0038] In this embodiment, the operation of the servo motor 2 causes the fan blades 3 to rotate, which in turn exhausts indoor gas to the outside. The gas concentration sensor 5 monitors the indoor gas concentration in real time and compares the received gas concentration value with a preset value. If the gas concentration value is high, the microcontroller 7 will increase the speed of the servo motor 2, thereby increasing the exhaust volume of the equipment. If the gas concentration value is low, the microcontroller 7 will slow down the speed of the servo motor 2 without affecting the exhaust, thus saving energy. When the gas concentration sensor 5 needs to be disassembled for maintenance, both push rods 603 are pressed inward simultaneously, causing the locking frame 602 to rotate. The sensor moves and separates from the locking block 608. Then, the connecting bracket 606 is pulled upward. After the pressure plate 607 separates from the gas concentration sensor 5, it can be removed for maintenance. During installation, the sensor is placed on top of the mounting bracket 4, and then both connecting brackets 606 are pressed down simultaneously. The connecting bracket 606 drives the locking block 608 and the pressure plate 607. The locking block 608 squeezes the locking bracket 602. When the inclined surface of the locking block 608 separates from the inclined surface of the locking bracket 602, the spring 605 causes the locking bracket 602 to reset and lock onto the locking block 608, thus positioning the connecting bracket 606. At this time, the pressure plate 607 is in contact with the top of the gas concentration sensor 5, completing the positioning and installation of the gas concentration sensor 5.

[0040] like Figure 1-5 As shown, based on Embodiment 1, a filter structure 8 for purifying gas is provided on one side of the body 1. An air inlet pipe 9 is provided on one side of the filter structure 8. The filter structure 8 includes an installation pipe 801 for installation. An activated carbon plate 802 and a filter plate 803 are movably installed inside the installation pipe 801. Two longitudinal grooves 805 are provided inside the installation pipe 801, and two transverse grooves 806 are provided on each longitudinal groove 805. Two rectangular blocks 804 are provided on the outside of both the activated carbon plate 802 and the filter plate 803. The rectangular blocks 804 and the longitudinal grooves 806... The grooves 805 and 806 are compatible. The rectangular block 804, the longitudinal groove 805 and the lateral groove 806 facilitate the disassembly of the activated carbon plate 802 and the filter plate 803. Before entering the machine body 1, the gas enters the installation pipe 801. The filter plate 803 and the activated carbon plate 802 filter the gas in sequence. The filter plate 803 can filter and block impurity particles to prevent impurity particles from entering the equipment and causing wear on the impeller. The activated carbon plate 802 can purify the gas and remove some of the unpleasant odor inside the gas.
