Description

Technical Field

[0001] The invention belongs to the technical field of temperature and humidity monitoring, and in particular relates to a temperature and humidity device for environmental monitoring. Background Art

[0002] The working principle of the temperature and humidity monitor mainly relies on the built-in temperature and humidity sensor. The sensor converts the temperature and humidity in the environment into electrical signals. After being processed and converted by the internal circuit, these electrical signals are converted into digital signals and displayed on the screen. Some devices also support wireless transmission of data to the cloud or a designated server to achieve remote monitoring and management.

[0003] Existing equipment generally installs it near the area where temperature and humidity are measured to ensure that temperature changes can be accurately sensed. However, general temperature monitoring is based on the changes in electrical properties such as resistance and voltage of the thermistor as the ambient temperature changes. The installation location needs to avoid interference from external factors such as direct sunlight and rain soaking as much as possible to ensure measurement accuracy. While monitoring humidity, it is inevitable to expose the semiconductor sensing point of the thermistor to the temperature measurement point area. For high-humidity environment detection, long-term monitoring in a high-humidity environment will reduce the sensitivity of temperature monitoring; on the other hand, an increase in altitude is usually accompanied by a decrease in temperature, which affects the humidity. The temperature and humidity detector is generally installed in a hanging or fixed manner. At this time, the environmental changes cannot be fully sensed, thereby reducing the monitoring accuracy.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-7 A temperature and humidity device for environmental monitoring shown in the figure includes a high-precision temperature and humidity monitoring device 1, the high-precision temperature and humidity monitoring device 1 includes a fixed frame 2, a temperature and humidity detection box 3, a sliding lifting platform 4, a movable bracket 5, a temperature sensor 6, a humidity sensor 7, a moisture absorption component 8 and a rotating component 9, the temperature and humidity detection box 3 is installed on one side of the wall for fixing the temperature and humidity detection box 3, the fixed frame 2 is installed on the top of the temperature and humidity detection box 3, the sliding lifting platform 4 is slidably sleeved on the outside of the fixed frame 2, the rotating component 9 is installed on the outside of the sliding lifting platform 4, the movable bracket 5 is fixedly connected to one side surface of the rotating component 9, the temperature sensor 6 and the humidity sensor 7 are installed on both sides of the bottom of the movable bracket 5, and the moisture absorption component 8 is installed on the inner side of the temperature sensor 6; The temperature and humidity detection box 3 is fixed to the wall by bolts and is used to support the fixed frame 2. The sliding lifting platform 4 is used to move up and down inside the fixed frame 2. The rotating component 9 is used to drive the movable bracket 5 to rotate and control the monitoring position of the temperature sensor 6 and the humidity sensor 7. The movable bracket 5 is used to connect the temperature sensor 6 and the humidity sensor 7. The conductor sensing end of the humidity sensor 7 is exposed to the outside and is in full contact with the surrounding environment of the monitoring point. The conductor sensing end of the temperature sensor 6 is located inside the moisture absorption component 8 and is used to isolate moisture.

[0022] The soft copper wire 30 is installed at the output terminal connection of the temperature sensor 6 and the humidity sensor 7 and is left with enough length to adapt to the lifting effect of the sliding lifting platform 4. Before measuring the temperature, the air in the high humidity environment will be fully dehumidified and filtered inside the sealed chamber 10, thereby reducing the moisture content in the air, thereby protecting the temperature measuring element and improving the measurement accuracy. When the temperature sensor 6 is monitoring, its semiconductor sensing head is always located in the sealed chamber 10, and cooperates with the small air pump 17 to complete the air collection at different heights, thereby protecting the temperature measuring element and improving its service life.

[0023] The moisture absorption component 8 includes a sealed chamber 10, a rotating handle 11, a connecting rod 12, a circular moisture-proof plate 13 and an exhaust component 14. The sealed chamber 10 is installed below the temperature sensor 6 for storing gases at different heights. The rotating handle 11 is rotatably connected to the outside of the sealed chamber 10, one end of the connecting rod 12 is rotatably connected to the inner wall surface of the sealed chamber 10, one side of the circular moisture-proof plate 13 is fixedly connected to the outer surface of the connecting rod 12, and the exhaust component 14 is installed on the outside of the sealed chamber 10 for exhausting the internal air of the sealed chamber 10.

[0024] When monitoring in a high humidity environment, the device can place the movable bracket 5 in the lowest position, and manually rotate the rotating handle 11. The rotating handle 11 drives the connecting rod 12 to rotate through the meshing eccentric gears 31. The connecting rod 12 blocks the two sets of circular moisture-proof plates 13 at the outer air inlet end of the inner air collecting chamber 32 of the sealed chamber 10, so that the air entering the interior can be fully absorbed by the two sets of circular moisture-proof plates 13, thereby improving the internal dryness of the air collecting chamber 32, so that the sensing conductor of the temperature sensor 6 is prevented from being immersed in a humid environment for a long time, thereby improving its service life. When in a dry environment, the rotating handle 11 can be rotated again to rotate the circular moisture-proof plate 13 back to the sealed chamber 10 away from the outer side of the air inlet end of the air collecting chamber 32. When the circular moisture-proof plate 13 is in the working position without blocking the air collecting chamber 32, it is embedded in the sealed chamber 10 and does not come into contact with the air in large quantities, thereby ensuring the dryness of the circular moisture-proof plate 13.

[0025] The vacuum assembly 14 includes an exhaust pipe 15, a one-way valve 16 and a small air pump 17. The output end of the small air pump 17 passes through the interior of the sealed chamber 10 and fits tightly with the inner surface of the sealed chamber 10. One side of the exhaust pipe 15 is clamped with the output end of the small air pump 17, and the one-way valve 16 is installed on the outside of the exhaust pipe 15.

[0026] In order to facilitate the air intake effect of the sealed chamber 10 at different heights, this product can start the small air pump 17 on the outside. Under negative pressure, the gas is drawn into the sealed chamber 10 along the outer air intake pipe 33. When the detection is completed, the one-way valve 16 is opened to discharge the internal air. The monitoring data at this height is recorded in the module of the temperature and humidity detection box 3, which is convenient for subsequent data detection and integration at different heights and improves the detection accuracy.

[0027] The rotating assembly 9 includes a mounting seat 18, a stepper motor 19 and a rotating shaft 20. The mounting seat 18 is installed on the outside of the sliding lifting platform 4. The stepper motor 19 is installed on the outside of the mounting seat 18 for connecting to the rotating shaft 20. The outside of the rotating shaft 20 is fixedly connected to the top of the movable bracket 5.

[0028] By starting the stepper motor 19 to drive the rotating shaft 20 to rotate, the rotating shaft 20 drives the movable bracket 5 to rotate along the axis. At this time, when they are at the lowest point, the heights of the temperature sensor 6 and the humidity sensor 7 are lower than the heights of the sliding lifting platform 4. When they are at the highest point, the heights of the temperature sensor 6 and the humidity sensor 7 are higher than the heights of the sliding lifting platform 4, thereby expanding the detection range.

[0029] A lifting assembly 21 is also provided inside the fixed frame 2. The lifting assembly 21 includes a servo motor 22, a drive shaft 23, an alloy worm 24, a rotating shaft 25, a locking gear 26 and an auxiliary support 27. The servo motor 22 is installed on the top of the fixed frame 2. The drive shaft 23 passes through the inner side of the top of the fixed frame 2 and is fixedly connected to the motor shaft of the servo motor 22 through a coupling. The alloy worm 24 is welded to the outer side of the middle part of the drive shaft 23. The rotating shaft 25 is rotatably connected to the inside of the fixed frame 2. The locking gear 26 is sleeved on the outer side of the rotating shaft 25 for engaging the alloy worm 24. The auxiliary support 27 passes through the inside of the sliding lifting platform 4 for limiting the moving direction of the sliding lifting platform 4.

[0030] An inner rack 28 meshing with the outer teeth of the locking gear 26 is also provided on the inner side of the sliding lifting platform 4 .

[0031] A through hole 29 having a size matching that of the auxiliary support 27 is formed through the interior of the sliding lifting platform 4 .

[0032] The outside of the connection terminals of the temperature sensor 6 and the humidity sensor 7 are also clamped with a soft copper wire 30 , and the output end of the soft copper wire 30 is clamped with the incoming line end of the temperature and humidity detection box 3 .

[0033] The opposite sides of the rotating handle 11 and the connecting rod 12 are also provided with mutually meshing eccentric gears 31 .

[0034] In order to facilitate the stable movement of the temperature sensor 6 and the humidity sensor 7 along the Z-axis direction, the device can start the servo motor 22 on the top of the fixed frame 2, the servo motor 22 drives the drive shaft 23 to rotate, and the drive shaft 23 drives the alloy worm 24 to rotate. Since the inner side of the outer spiral surface of the alloy worm 24 is meshed with the locking gear 26, the alloy worm 24 can achieve a synchronous self-locking effect when driving the locking gear 26 to rotate; on the other hand, with the cooperation of the embedded rack 28, the sliding lifting platform 4 can stably translate in the Z-axis direction along the outer side of the auxiliary support 27 in the opening direction of the through hole 29. With the help of the longer soft copper wire 30, the temperature sensor 6 and the humidity sensor 7 can detect the temperature and humidity of the air at different heights, thereby improving the use effect of the device.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
