Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a gas sensor that is easy to install. Background Technology

[0002] A gas sensor is an electronic device used to detect the concentration of a specific gas in the air. They are widely used in air quality monitoring, industrial safety, environmental protection, medical equipment, and smart homes. Depending on the type of gas detected and the application scenario, gas sensors come in a wide variety of types, such as electrochemical gas sensors, semiconductor gas sensors, and infrared gas sensors.

[0003] However, traditional gas sensors typically rely on ambient natural wind or static airflow, making it difficult to guarantee a continuous and sufficient gas sample. This results in long detection response times or low accuracy, and makes it difficult to ensure that airflow can enter the sensor normally for detection while minimizing rainwater entering the device, thus reducing the sensor's applicability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an easy-to-install gas sensor. This gas sensor is equipped with a conveying mechanism that, with the assistance of external wind, rotates a large fan blade. This, combined with bevel gear transmission, allows a small fan blade to draw external airflow into the sensor module through the air inlet, thereby improving the sensor's detection efficiency and reducing energy consumption. Furthermore, the drainage cover reduces the entry of rainwater, dust, and other impurities into the device, enhancing its durability and reliability. This allows the gas sensor to reduce rainwater ingress while ensuring stable airflow into the sensor, thus expanding its applicable range.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An easy-to-install gas sensor includes a base with an installation mechanism at its rear end. The installation mechanism includes a first fixing plate and a positioning block. A support plate is fixedly connected to the center of the front outer wall of the first fixing plate. A positioning slot is formed on the upper part of the front outer wall of the support plate. A connecting bracket is fixedly connected to one end of the rear outer wall of the first fixing plate. A first connecting strip is hinged to the other side of the rear outer wall of the first fixing plate. A second fixing plate is hinged to the end of the first connecting strip away from the first fixing plate. A threaded rod is threaded at the center of the rear outer wall of the second fixing plate. A second connecting strip is hinged to the end of the second fixing plate away from the first connecting strip. A connecting clip is fixedly connected to the end of the second connecting strip away from the second fixing plate.

[0007] The upper end of the base is provided with a conveying mechanism, which includes a ventilation shell and a threaded groove. The upper end of the outer wall of the ventilation shell has multiple air inlets. A flow guide cover is fixedly connected to the upper surface of the ventilation shell. A rotating seat is rotatably connected to the center of the upper surface of the flow guide cover. A support rod is fixedly connected to the center of the upper surface of the rotating seat.

A first bevel gear is fixedly connected to the upper surface of the first transmission rod. A wind vane is fixedly connected to the upper surface of the support rod. A second transmission rod is rotatably connected to the middle of the outer wall of the rear end of the wind vane. A second bevel gear is fixedly connected to the outer wall of the front end of the second transmission rod. A large fan blade is fixedly connected to the outer wall of the rear end of the second transmission rod.

[0008] With the above technical solution, the gas sensor is equipped with an installation mechanism that allows users to quickly install it by engaging the connector between the connector and the connector head. The locking mechanism of the threaded rod further restricts and fixes the position, making it easier and faster for users to install and fix the sensor.

[0009] Furthermore, the first fixing plate is engaged with the base via a support plate, and the positioning block is fixedly connected to the rear end of the outer wall of the support plate, and the positioning block is engaged with the positioning slot.

[0010] The above technical solution enables the base to be installed on the mounting mechanism via a snap-fit ​​method.

[0011] Furthermore, the connecting bracket and the connecting head engage with each other, and rubber pads are fixedly connected to the middle of the inner walls of the first fixing plate and the second fixing plate.

[0012] The above technical solution enables the installation mechanism to be securely fixed to the pole.

[0013] Furthermore, a rotating handle is fixedly connected to the outer wall of the rear end of the threaded rod, and a rubber block is fixedly connected to the outer wall of the front end of the threaded rod;

[0014] The above technical solution allows the user to rotate the threaded rod by turning the handle, thereby enabling the rubber block to be tightly squeezed against the object to be clamped, allowing the installation mechanism to position the gas sensor.

[0015] Furthermore, the ventilation housing is threaded into the middle of the upper surface of the base, the threaded groove is formed on the upper surface of the base, and a threaded block is fixedly connected to the lower surface of the ventilation housing, the threaded block being threaded into the threaded groove.

[0016] The above technical solution enables users to separate the ventilation shell from the base by rotating the ventilation shell.

[0017] Furthermore, the first bevel gear meshes with the second bevel gear;

[0018] Through the above technical solution, the first transmission rod can transmit power to the second transmission rod, thereby enabling the large fan blade to drive the small fan blade.

[0019] Furthermore, a storage battery is fixedly connected to the lower end of the base, and a placement groove is provided at the center of the lower surface of the base. A sensor module is fixedly connected to the upper end of the inner wall of the placement groove, and the sensor module is electrically connected to the storage battery.

[0020] The above technical solution enables the battery to provide power to the sensor module, thereby enabling the sensor module to detect the airflow flowing in the placement tank.

[0021] Furthermore, a cover plate is threadedly fitted to the center of the lower surface of the base, a filter screen is fixedly connected to the center of the inner wall of the cover plate, and a hexagonal block is fixedly connected to the center of the lower surface of the cover plate.

[0022] The above technical solution enables users to rotate and disassemble the cover plate by engaging a wrench with a hexagonal block.

[0043] Working principle: First, the first fixing plate 201 is attached to the column or thick tree branch to be installed.

The connecting clip 2012 is then engaged with the connecting clip seat 204. Next, by rotating the handle 209, the threaded rod 208 is rotated, causing the rubber block 2010 and rubber pad 207 to be firmly pressed and adhered to the column or thick tree branch. The friction of the rubber pad 207 itself reduces the possibility of the threaded rod 208 moving or rotating. Finally, the base 1 is connected to the fixed... The sensor module 6 is mounted on the support plate 202 with the slot 203 engaging. A small fan (ADDA mini fan blade) is installed inside the sensor module 6 and rotates at low speed so that the sensor can be used normally in windless weather. When there is wind, the large fan blade 3014 generates power to the second transmission rod 3012 under the guidance of the wind vane block 3011. Under the meshing of the bevel teeth, the power is transmitted to the small fan blade 309 through the first transmission rod 308, thereby assisting the external airflow to enter the sensor through the air inlet 304. After the detection is completed, the airflow is discharged through the filter screen 8, thereby reducing the possibility of the device being corroded by rainwater from the outside.
