Description

Technical Field

[0001] This utility model relates to the field of formaldehyde, and in particular to a device for detecting the concentration of formaldehyde in the air. Background Technology

[0002] Formaldehyde is a colorless organic compound with a pungent odor, commonly used in chemical production, but it is harmful to human health.

[0003] Devices used to detect formaldehyde concentration in the air are called air formaldehyde concentration detectors. These devices can help people detect and measure the formaldehyde content in indoor air in a timely manner, thereby ensuring the safety and health of their living or working environment.

[0004] An existing device for detecting formaldehyde concentration in the air has the following shortcomings:

[0005] Most materials used in home renovations release formaldehyde directly or indirectly, causing indoor environmental pollution that seriously endangers human health. Therefore, formaldehyde testing is essential. In the practical application of existing technology, most devices are equipped with casters at the bottom for easy indoor movement. However, such designs with only casters lack supporting fixing measures, making the device prone to displacement under external forces and difficult to stably stop at the designated testing location. This not only affects the convenience of the testing operation but may also lead to deviations in the test data, failing to accurately reflect the formaldehyde concentration at that location. Utility Model Content

[0006] This invention avoids the problem of displacement due to external forces when relying solely on the moving wheel, ensuring accurate test data and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a device for detecting formaldehyde concentration in air, comprising a fixing mechanism, wherein a detection mechanism is fixedly connected to the top of the fixing mechanism; the fixing mechanism includes a base plate, the top of the base plate having a set of slots, a set of fixing plates being slidably connected to the inner wall of the slots, a first servo motor being fixedly installed on the top of the fixing plates, a set of threaded rods being fixedly connected to the output end of the first servo motor, a set of threaded cylinders being threadedly connected to the outer wall of the threaded rods, a set of movable plates being fixedly connected to the bottom of the threaded cylinders, a connecting rod being fixedly connected to the bottom of each movable plate, a set of lifting plates being fixedly connected to the bottom of each connecting rod, and a set of anti-slip pads being fixedly connected to the bottom of each lifting plate. Through the above components, the anti-slip pads contact the ground, effectively fixing the device at the designated detection position and ensuring stable device parking.

[0008] Preferably, a push handle is fixedly connected to the top of the base plate, and a PLC controller is fixedly installed on the outer wall of the push handle. The PLC controller is electrically connected to the components to control the opening and closing of the components.

[0009] Preferably, the inner wall of the fixed plate is slidably connected with a slider, and the outer wall of the slider is fixedly connected to the outer wall of the movable plate. The slider can guide the movement of the movable plate, restrict the movable plate to move only in a specific direction, avoid the movable plate from deviating or shaking during the movement, and ensure the stability of the lifting plate and anti-slip pad lifting movement.

[0010] Preferably, the inner wall of each fixed plate is fixedly connected with a guide rod, the outer wall of the guide rod is slidably connected to the inner wall of the slider, and the guide rod is slidably connected to the slider, which further enhances the guiding and supporting effect on the slider, making the slider move more smoothly when it drives the movable plate.

[0011] Preferably, the outer wall of the fixing plate is threaded with bolts, and the top of the base plate is threaded with holes. The inner wall of the threaded hole is threaded to the inner wall of the bolt. The bolt is threaded to the threaded hole, which can firmly fix the fixing plate to the base plate and facilitate the assembly and disassembly of the fixing plate.

[0012] Preferably, a set of rotating rods is movably inserted into the inner wall of the base plate, and wheels are fixedly connected to the outer walls of each rotating rod. A first pulley is fixedly connected to the outer wall of one of the rotating rods. A set of first connecting plates is fixedly connected to the top of the base plate. A second pulley is movably inserted into the inner wall of the first connecting plate. A synchronous belt is fitted onto the inner walls of the second pulley and the first pulley. The synchronous belt is connected to the second pulley and the first pulley by frictional transmission. The cooperation of the rotating rods, wheels, first pulley, synchronous belt, second pulley and other components constitutes the mobile transmission mechanism of the equipment. Power is transmitted through belt transmission, causing the wheels to rotate and drive the equipment to move. The transmission is smooth and the structure is simple, which is conducive to the flexible movement of the equipment between different positions indoors.

[0013] Preferably, a second servo motor is fixedly installed on the front side of the first connecting plate. The output end of the second servo motor is fixedly connected to the front side of the second pulley. The second servo motor provides power for the movement of the equipment. Its output end is connected to the second pulley, which can accurately control the rotation speed of the second pulley, thereby controlling the movement speed of the equipment and enabling the equipment to move quickly to the designated testing location.

[0014] Preferably, the detection mechanism includes a housing, with a second connecting plate fixedly connected to the inner wall of the housing. An exhaust fan is fixedly installed on the inner wall of the second connecting plate. A formaldehyde sensor is fixedly installed on the inner wall of the housing. The exhaust fan can draw outside air into the housing, allowing the air to fully contact the formaldehyde sensor. The formaldehyde sensor can quickly and accurately detect the formaldehyde concentration in the air, providing core concentration data for the detection work and ensuring the validity of the detection results.

[0015] Preferably, an audible and visual alarm is fixedly installed on one side of the front of the box, an air vent is fixedly connected to the front of the box, and a baffle is fixedly connected to the top of the box. When the formaldehyde concentration exceeds the standard, the audible and visual alarm can promptly sound an alarm through sound and light to remind the operator to pay attention to the indoor formaldehyde pollution. The air vent can discharge the tested air from the box to ensure air circulation inside the box and not affect subsequent testing.

[0016] Preferably, a storage battery is fixedly installed on the inner wall of the enclosure. The storage battery provides power to the device, freeing it from dependence on external power sources. Formaldehyde detection can be performed anywhere indoors without being limited by the location of power outlets, greatly enhancing the mobility and range of use of the device. It is especially suitable for indoor environmental testing in areas where the power has not yet been connected after renovation.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0018] 1. In this utility model, the bottom of the equipment is equipped with a fixing mechanism. The first servo motor drives the threaded rod to rotate, which in turn drives the threaded cylinder, movable plate, connecting rod and lifting plate to move, so that the anti-slip pad contacts the ground and stabilizes the equipment in the designated testing position. This avoids the problem of easy displacement due to external force when relying solely on the moving wheels, and ensures the accuracy of the test data. At the same time, the equipment is equipped with a moving transmission mechanism consisting of a rotating rod, wheels, pulleys, synchronous belt and a second servo motor. Power is transmitted through belt drive, the moving speed is precisely controlled, and the equipment can flexibly adapt to the testing needs of multiple locations.

[0019] 2. In this utility model, the slider is fixedly connected to the movable plate and slides on the inner wall of the fixed plate. Combined with the cooperation of the guide rod and the slider, it provides guidance and support for the movement of the movable plate, ensuring that it moves only in a specific direction and avoiding deviation or shaking. This ensures the stability of the lifting process of the lifting plate and the anti-slip mat. In addition, the exhaust fan in the detection mechanism can draw outside air into the box, allowing it to fully contact the formaldehyde sensor, ensuring that the sensor can quickly and accurately detect the formaldehyde concentration, providing a guarantee for core data. At the same time, the audible and visual alarm can promptly issue an alarm through sound and light when the formaldehyde concentration exceeds the standard, reminding the operator to take action.

The air vent 203 can discharge the tested air inside the enclosure 201 to ensure air circulation inside the enclosure 201 and not affect subsequent testing.

[0037] like Figure 4As shown, a storage battery 207 is fixedly installed on the inner wall of the enclosure 201.

[0038] The operation and working principle of this device are as follows: When the equipment needs to be moved, the second servo motor 106 is started via the button on the PLC controller 112. Its output drives the second pulley 109 to rotate. The second pulley 109 forms a frictional transmission with the first pulley 107 through the synchronous belt 108, causing the first pulley 107 to drive the rotating rod 105 to rotate. The wheel 104 on the rotating rod 105 rotates accordingly, realizing the movement of the equipment. At the same time, the push handle 111 can assist in pushing. The PLC controller 112 controls the operation of each component. When the equipment reaches the designated detection position and needs to be fixed, the first servo motor 114 is started, driving the threaded rod 115 to rotate. The threaded cylinder 116, which is threadedly connected to the threaded rod 115, drives the movable plate 117 to move. 17. The slider 122 slides on the guide rod 123 on the inner wall of the fixed plate 113 to ensure smooth movement. The movable plate 117 drives the lifting plate 120 to descend through the connecting rod 121, so that the anti-slip pad 119 at the bottom of the lifting plate 120 contacts the ground and fixes the equipment. During testing, the exhaust fan 206 is fixed in the box 201 through the second connecting plate 205 to draw outside air into the box 201. After the air comes into contact with the formaldehyde sensor 208, the sensor can detect the formaldehyde concentration and display the test results in real time. The user can view the data through the display screen of the PLC controller 112. If the formaldehyde concentration exceeds the standard, the audible and visual alarm 204 will sound an alarm. The detected air is discharged through the exhaust plate 203, and the battery 207 provides power support for the entire equipment.
