Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 This utility model provides an embodiment of a temperature and humidity monitoring and alarm device, including a monitoring and alarm component 1 and a locking component 2. The locking component 2 is movably snapped onto the monitoring and alarm component 1. The monitoring and alarm component 1 includes a power supply box 3 and a fixing plate 9. A humidity sensor 4 and a temperature sensor 5 are fixedly installed at the front end of the power supply box 3. A PLC controller 6 is fixedly installed at the top of the power supply box 3. Four seven-color sound and light alarms 7 are evenly fixedly installed at the top of the power supply box 3. A limiting arc plate 8 is fixedly connected to the middle of one side of the power supply box 3. The fixing plate 9 is fixedly installed in the middle of the side of the power supply box 3 away from the humidity sensor 4. A limiting plug-in plate 12 is provided at one end of the fixing plate 9 that snaps onto the limiting arc plate 8. The locking component 2 includes a support plate 15. A tensile arc plate 17 is fixedly connected to one side of the support plate 15 to increase the support strength of the support plate 15. A locking bolt 16 is threadedly connected to the middle of the support plate 15. A plug-in rod 19 is fixedly connected to one end of the support plate 15 away from the tensile arc plate 17.

[0021] A limiting groove 11 is provided at one end of the fixed plate 9 near the limiting arc plate 8. The limiting plug plate 12 is slidably connected to the inner side of the limiting groove 11. A metal spring 14 is provided on the inner side of the limiting groove 11. The metal spring 14 is located at the end of the limiting plug plate 12 away from the limiting arc plate 8. The plug rod 19 is movably plugged into the inner side of the limiting arc plate 8. A limiting plug groove 20 is evenly provided on one side of the plug rod 19 near the middle of the support plate 15. The limiting plug plate 12 is engaged with the inner side of the limiting plug groove 20. The elasticity of the metal spring 14 applies a pushing force to the limiting plug plate 12, causing the limiting plug plate 12 to be plugged into the inner side of the limiting plug groove 20.

[0022] A toggle plate 13 is fixedly connected to the side of the limiting plug plate 12 away from the power supply box 3. The limiting plug plate 12 can be moved by toggling the toggle plate 13.

[0023] A positioning groove 10 is provided in the middle of the side of the fixing plate 9 away from the power box 3. The locking bolt 16 is positioned corresponding to the positioning groove 10. A rubber pad 18 is fixedly connected to the end of the locking bolt 16 near the plug rod 19. The support steel pipe is located between the fixing plate 9 and the support plate 15, and the support steel pipe is stuck inside the positioning groove 10. Rotating the locking bolt 16 moves the rubber pad 18 toward the fixing plate 9 until the rubber pad 18 is tightly attached to the outside of the support steel pipe for fixation. The rubber pad 18 can increase the friction force, thereby increasing the fixation strength.

[0024] The temperature and humidity threshold range is set by the PLC controller 6. The PLC controller 6 is wired to the humidity sensor 4 and the temperature sensor 5 through its built-in data processing module. The humidity sensor 4 and the temperature sensor 5 transmit the detected signals to the data processing module in the PLC controller 6. The data processing module analyzes and processes the signals. When the temperature and humidity exceed the threshold range, the data processing module sends the signal to the control module of the PLC controller 6 for processing. The PLC controller 6 is wired to the seven-color sound and light alarm 7 through its built-in control module. When the control module of the PLC controller 6 receives the corresponding alarm command, the PLC controller 6 controls the seven-color sound and light alarm 7 of the corresponding color to turn on the alarm. The power supply box 3 is wired to the humidity sensor 4, the temperature sensor 5, the PLC controller 6 and the seven-color sound and light alarm 7 to provide power.

[0025] The plug rod 19 has a hollow design, which reduces material consumption and lightens the overall weight of the device.

[0026] Working Principle: During use, first, set the temperature and humidity threshold ranges, and assign different colors to the four seven-color sound and light alarms 7 according to different temperature and humidity conditions. Then, adjust the distance between the fixed plate 9 and the support plate 15 according to the diameter of the supporting steel pipe in the greenhouse. Push the actuating plate 13 away from the limiting arc plate 8 by external force. The movement of the actuating plate 13 causes the limiting insertion plate 12 to slide inside the limiting groove 11, approaching and squeezing the metal spring 14 until it retracts. This continues until the limiting insertion plate 12 completely disengages from the inner side of the limiting insertion slot 20 and enters the inner side of the limiting groove 11. Then, push and pull the support plate 15, causing the insertion rod 19 to move inside the limiting arc plate 8. The support plate 15 moves until the distance between the support plate 15 and the fixed plate 9 is approximately 1 cm greater than the diameter of the supporting steel pipe, and one of the limiting insertion slots 20 and the limiting insertion plate 12 are aligned. Then, remove the force applied to the actuating plate 13. At this point, the metal spring 14 loses its compression, releases its elastic potential energy, and rebounds, pushing... The movable limit plug plate 12 moves closer to the limit arc plate 8 until one end of the limit plug plate 12 away from the fixed plate 9 is inserted into the inner side of the limit plug groove 20. Then, the device is placed on the outside of the support steel pipe by external force, and the support plate 15 is pushed so that the support steel pipe is between the fixed plate 9 and the support plate 15. Then, the power supply box 3 is moved to place the outside of the support steel pipe against the inside of the positioning groove 10. When the diameter of the support steel pipe is larger than the diameter of the positioning groove 10, the support steel pipe is locked in the positioning groove 10. Then, the locking bolt 16 is tightened by external force to move the rubber pad 18 closer to the support steel pipe until the rubber pad 18 is tightly against the outside of the support steel pipe. When the signals detected by the humidity sensor 4 and the temperature sensor 5 are transmitted to the PLC controller 6, the PLC controller 6 processes the signals through the data processing module. When the temperature and humidity data exceed the threshold range and show an abnormality, the PLC controller 6 controls the corresponding color seven-color sound and light alarm 7 to activate the sound and light alarm to remind the staff.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
