Description

Technical Field

[0001] The invention relates to the technical field of test and detection devices, in particular to a constant temperature and humidity test and detection device for pipelines. Background Art

[0002] Constant temperature and humidity test chamber is a kind of equipment used to simulate various environmental conditions for experiments and tests. It can control the temperature and humidity in the chamber to keep it at a stable level to meet the needs of different experimental conditions. Constant temperature and humidity test chambers are widely used in electronics, electrical engineering, instrumentation, plastics, metals, food, chemicals, textiles and other industries to test the performance and stability of products under different temperature and humidity conditions.

[0003] For example, the Chinese patent with the announcement number CN118002216A discloses a constant temperature and humidity test box with efficient internal temperature and humidity monitoring, including a box body, a box door, a temperature adjustment unit and a humidity adjustment unit. The box body has an inner cavity, and a placement rack, a first temperature sensor and a first humidity sensor are installed in the inner cavity. The box door is hinged to the box body, and a detection unit is provided at the box door. The detection unit includes a second temperature sensor and a second humidity sensor.

[0004] In the above patent, multiple first temperature sensors and multiple humidity sensors arranged in the box body are independently detected to avoid failure of the temperature sensor and humidity sensor integrated in the constant temperature and humidity test box.

Embodiment 2:

[0020] On the basis of Example 1, in order to be able to quickly install several pipeline bodies, the detection and installation mechanism includes a connecting column 25, the two ends of the connecting column 25 are cylindrically arranged, and two connecting plates 7 are fixedly connected to the outer sides of the connecting column 25. The opposite surfaces of the two connecting plates 7 are fixedly connected to arc-shaped support plates 28.

One end of the connecting column 25 is movably connected to the detection box 1, and extends out of the detection box 1 and fixed to the disc 5. Fixed connection, the disc 5 is threaded with a limit screw 6, one end of the limit screw 6 is threaded into the internal threaded hole 4, the internal threaded hole 4 is opened in the outer side of the detection box 1, loosen the fixing nut 26 to make the first U-shaped rod 27 in a movable state, place the pipeline body above the arc support plate 28, and reinstall the first U-shaped rod 27 after placement, so that the pipeline body is installed above the two arc support plates 28. By unscrewing the limit screw 6 and rotating the disc 5, the connecting column 25 can be in a rotating state, and several pipeline bodies can be installed by rotating the connecting column 25; The transmission mechanism includes a connecting block 15, and a groove 31 is provided in the connecting block 15 near one end of the connecting column 25. One end of the connecting column 25 is inserted into the groove 31. Since the insertion end of the connecting column 25 and the groove 31 are both cylindrical, the connecting column 25 will not rotate with the connecting block 15 during the rotation of the connecting block 15. A transmission motor 16 is fixedly connected to the outside of the detection box 1. The output end of the transmission motor 16 extends into the detection box 1 and is fixedly connected to the connecting block 15. A cavity 32 is provided in the connecting block 15. The connecting pipe 30 and the circular retaining ring 29 are movably connected to the cavity 32. When the transmission motor 16 drives the connecting block 15 to rotate, since the connecting pipe 30 is in a fixed state, the circular retaining ring 29 will move along the cavity 32 during the rotation of the connecting block 15. A temperature detector 34 and a humidity detector 35 are fixedly connected to one side of the two connecting plates 7 on one side.

[0021] The inner wall cleaning mechanism includes a second U-shaped rod 13, a plurality of rubber scrapers 14 are fixedly connected to the outside of the second U-shaped rod 13, a liquid guide cavity 33 is opened in the second U-shaped rod 13, and the liquid guide cavity 33 is connected to the cavity 32. The opposite surfaces of the two second U-shaped rods 13 are fixedly connected to a plurality of atomizing nozzles 10, and the atomizing nozzles 10 are connected to the liquid guide cavity 33. The plurality of atomizing nozzles 10 can be divided into two types of atomizing nozzles 10 with different apertures, so that the atomizing nozzles 10 with corresponding apertures can be controlled to spray water mist into the detection box 1 according to the humidity in the detection box 1. The opposite surfaces of the two second U-shaped rods 13 are fixed A heating light bar 11 is connected, and the transmission motor 16 is turned on to drive the connecting block 15 connected to its output end to start rotating. The connecting block 15 rotates to drive the first U-shaped rod 27 to start rotating. The first U-shaped rod 27 rotates to drive several atomizing nozzles 10 to rotate synchronously. The rotating atomizing nozzles 10 can evenly spray water mist into the detection box 1. By turning on the heating light bar 11 connected to the first U-shaped rod 27, the detection box 1 can be heated. By turning on the temperature detector 34 and the humidity detector 35, the temperature and humidity in the detection box 1 can be detected. Both sides of the second U-shaped rod 13 are fixedly connected with water storage boxes 37; A baffle 17 is movably connected in the second U-shaped rod 13, and a plurality of through holes 24 are provided in the baffle 17. The baffle 17 is fixedly connected to the output end of the telescopic cylinder 9, and the telescopic cylinder 9 is fixedly installed in the second U-shaped rod 13. The temperature and humidity in the detection box 1 can be detected by turning on the temperature detector 34 and the humidity detector 35. When it is detected that the humidity in the detection box 1 is high, the telescopic cylinder 9 starts to drive the baffle 17 to start moving, and the baffle 17 drives the through holes 24 provided therein to move. When the through holes 24 move, they are connected with the other two groups of atomizing nozzles 10 with smaller apertures. At this time, the water mist sprayed by the atomizing nozzle 10 becomes smaller, thereby reducing the humidity in the detection box 1; A lifting plate 20 is provided at the lower end of the liquid guiding tube 19, and two T-shaped rods 22 are fixedly connected to the upper end of the lifting plate 20. The T-shaped rods 22 are slidably connected in the sliding cavity 21, and the sliding cavity 21 is opened in the lower end of the liquid guiding tube 19. A connecting spring 23 is sleeved on the outer side of the T-shaped rod 22, and one end of the connecting spring 23 is fixedly connected to the T-shaped rod 22, and the other end is fixedly connected to the sliding cavity 21. When the water source entering the bottom of the inner side of the detection box 1 accumulates to a certain weight, the lifting plate 20 will move downward at this time, and the water source entering the liquid guiding tube 19 will enter the water storage cavity 2 and be stored. When the water source accumulated in the detection box 1 is discharged into the water storage cavity 2, the lifting plate 20 will return to its original position under the elastic force of the connecting spring 23 to prevent the water vapor in the water storage cavity 2 from entering the detection box 1 and affecting the humidity in the detection box 1; A guide wheel 3 is fixedly connected to one end of the second U-shaped rod 13 . The guide wheel 3 is slidably connected to a guide groove 8 . The guide groove 8 is formed on the inner wall of the detection box 1 .

[0022] Working principle: when in use, the pipeline body is installed in the detection installation mechanism as needed. Specifically, loosen the fixing nut 26 to make the first U-shaped rod 27 movable, and place the pipeline body above the arc support plate 28. After placement, reinstall the first U-shaped rod 27 so that the pipeline body is installed above the two arc support plates 28. The connecting column 25 can be rotated by unscrewing the limit screw 6 and rotating the disc 5. Several pipeline bodies can be installed by rotating the connecting column 25. After installation, turn on the circulation pump 18. After the circulation pump 18 is started, the water source in the water storage chamber 2 is pumped into the connecting pipe 30. The water source enters the cavity 32 through the connecting pipe 30, and enters the liquid guide cavity 33 through the cavity 32. At this time, the water source is sprayed into the detection box 1 through the atomizing nozzle 10; Turn on the transmission motor 16 to drive the connecting block 15 connected to its output end to start rotating. The connection block 15 rotates to drive the first U-shaped rod 27 to start rotating. The first U-shaped rod 27 rotates to drive several atomizing nozzles 10 to rotate synchronously. The rotating atomizing nozzle 10 can evenly spray water mist into the detection box 1. By turning on the heating light bar 11 connected to the first U-shaped rod 27, the detection box 1 can be heated. By turning on the temperature detector 34 and the humidity detector 35, the temperature and humidity in the detection box 1 can be detected. When it is detected that the humidity in the detection box 1 is high, the telescopic cylinder 9 starts to drive the baffle 17 to start moving. The baffle 17 drives the through hole 24 opened therein to move. When the through hole 24 moves, it is connected with the other two groups of atomizing nozzles 10 with smaller apertures. At this time, the water mist sprayed by the atomizing nozzle 10 becomes smaller, thereby reducing the humidity in the detection box 1. The second U-shaped rod 13 drives the rubber scraper 14 connected to its outer side to start moving during the rotation process. The rubber scraper 14 moves along the circular cavity in the detection box 1, so that the water droplets adhering to the inner wall of the detection box 1 are scraped off. At the same time, when the rubber scraper 14 moves to the upper side, the scraped water droplets will enter the water storage box 37 to be stored, preventing the scraped water droplets from falling on the surface of the pipeline body. When the second U-shaped rod 13 is rotated to the lower side, the water source in the water storage box 37 will flow out. When the water source entering the bottom of the inner side of the detection box 1 accumulates to a certain weight, the lifting plate 20 will move downward, and the water source entering the liquid guide tube 19 will enter the water storage chamber 2 to be stored. When the water source accumulated in the detection box 1 is discharged into the water storage chamber 2, the lifting plate 20 will return to its original position under the elastic force of the connecting spring 23 to prevent the water vapor in the water storage chamber 2 from entering the detection box 1 and affecting the humidity in the detection box 1. When the detection is completed, turn off the circulation pump 18, open the box door 38 and take out the tested pipeline body.
