Description

Technical Field

[0001] The present invention relates to the technical field of test chambers, and particularly to a low-pressure temperature and humidity test chamber for environmental simulation. Background Art

[0002] The low-pressure temperature and humidity test chamber for environmental simulation can simulate a low-pressure environment such as high altitude by controlling the air pressure inside the chamber, and can usually achieve low-pressure conditions from normal atmospheric pressure to near vacuum (for example, air pressure below 1000 hPa). Through the built-in heating or cooling system, the temperature inside the temperature and humidity test chamber can be adjusted and set within a range from low temperature (such as -70°C) to high temperature (such as +150°C) to simulate different working environments. There are humidifying and dehumidifying systems in the device, which can accurately control the humidity range, usually between 20% - 98% RH.

[0003] In the prior art, the document with the publication number CN117030774A provides a low-pressure temperature and humidity test chamber for environmental simulation. This test chamber cooperates with a water leakage device through a pop-up device. When a large amount of water flows into the water leakage device, based on the Worthington jet principle, a jet is formed to impact the pop-up device and make it move upward, thereby ejecting the base of the broken glass cup out of the fixing groove, facilitating the cleaning by the test personnel.

[0004] When using the low-pressure temperature and humidity test chamber for environmental simulation to detect water pollution, a glass measuring cup is usually used to hold the water sample. However, after the detection, the glass measuring cup needs to be manually cleaned, and the residual pollutants may not be completely removed during the cleaning process. Especially for complex water pollutants such as organic compounds, even after cleaning, trace substances may still remain, and these residual substances may cause cross-contamination, thereby affecting the detection results of the water sample.

[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0022] As Figures 1 - 8An environmental simulation low-pressure temperature and humidity test chamber shown in the figure includes a test chamber main body 1. Inside the test chamber main body 1, a material guiding seat 2 is fixedly connected through. On the material guiding seat 2, two placing plates 3 are slidably and symmetrically arranged. On one side of the material guiding seat 2, a transmission mechanism 4 is rotatably connected. At the bottom end of the material guiding seat 2, a processing seat 5 is fixedly connected. Inside the processing seat 5, a push plate 6 is slidably arranged. On the push plate 6, a plastic cup processing plate 7 is slidably arranged. On one side of the push plate 6, a pressurizing mechanism 8 is rotatably connected. At the opening on one side of the processing seat 5, a material receiving seat 9 is placed.

[0023] As Figure 3 Shown in the figure, placing grooves 301 are formed on the placing plates 3. Disposable plastic cups 302 are placed on the two placing plates 3. One side of the placing plate 3 passes through the inner wall of the material guiding seat 2 and extends to the outside and is fixedly connected with a grooved rod 303. One end of the grooved rod 303 is fixedly connected with a tension spring 304. The other end of the tension spring 304 is fixedly connected with the inner wall of the material guiding seat 2.

[0024] When using the low-pressure temperature and humidity test chamber to detect water pollution, the disposable plastic cups 302 are used to hold water samples, eliminating the need for manual cleaning after each experiment, saving cleaning and preparation time. Especially when conducting a large number of water sample detections, the experimental efficiency is significantly improved, and at the same time, cross-contamination caused by incomplete cleaning of glass cups is avoided. This can ensure the independence of each water sample detection and improve the accuracy of test results.

[0025] As Figure 4 Shown in the figure, the transmission mechanism 4 includes a universal joint 401. One end of the universal joint 401 is rotatably connected to the outer wall of the material guiding seat 2. At the end of the universal joint 401 connected to the material guiding seat 2, a U-shaped rod 402 is fixedly connected. The two ends of the U-shaped rod 402 are respectively slidably arranged in the inner walls of the two grooved rods 303. The other end of the universal joint 401 passes through the inner wall of the test chamber main body 1 and extends into the processing seat 5 and is fixedly connected with a contact plate 403. Under the action of the tension spring 304, the grooved rod 303 will be driven to move, causing the grooved rod 303 to drive the connected placing plate 3 to move outward, so that the disposable plastic cup 302 above falls onto the mesh plate 501 in the processing seat 5 through the material guiding seat 2. When the push plate 6 resets, the contact rod 604 on the push plate 6 will contact and squeeze the contact plate 403, causing the universal joint 401 connected to the contact plate 403 to rotate, causing the universal joint 401 to drive the connected U-shaped rod 402 to rotate, and causing the two ends of the U-shaped rod 402 to slide in the two grooved rods 303, thereby driving the two placing plates 3 to automatically move closer and reset.

[0026] As Figure 5As shown, the inner wall of the processing seat 5 is of an inclined structure and fixedly connected with a net plate 501. One end of the net plate 501 is fixedly connected with an opening plate 502. A conical opening is provided on the opening plate 502. A plurality of jacks 503 are provided at the opening of the processing seat 5. A valve 504 is fixedly connected through the bottom end of the processing seat 5. When the push plate 6 continues to move, the flattened disposable plastic cup 302 will be pushed onto the opening plate 502 and fall into the receiving seat 9 through the opening plate 502 for collection.

[0027] As Figure 6 shown, one end of the push plate 6 is fixedly connected with a slider 601. The slider 601 is slidably matched with the inner wall of the processing seat 5. A lead screw 602 is threadedly connected to the slider 601. The lead screw 602 is rotatably connected through the inner wall of the processing seat 5. An outer end of the lead screw 602 is fixedly connected with a motor 603. The motor 603 is fixedly connected with the outer wall of the processing seat 5. The bottom end of the push plate 6 is in sliding contact with the net plate 501. The top end of the push plate 6 is fixedly connected with a contact rod 604. One end of the contact rod 604 is in sliding contact with the contact plate 403. By driving the connected lead screw 602 to rotate by the motor 603, the lead screw 602 drives the slider 601 to move. Then the slider 601 will drive the connected push plate 6. At this time, the contact rod 604 on the push plate 6 will not be in contact with the contact plate 403.

[0028] As Figure 7 shown, one end of the plastic cup processing plate 7 is fixedly connected with a moving block 701. The moving block 701 is slidably matched with the inner wall of the push plate 6. The other end of the plastic cup processing plate 7 is fixedly connected with an inclined plate.

[0029] As Figure 7 shown, the pressurizing mechanism 8 includes a threaded rod 801. One end of the threaded rod 801 is rotatably connected with the push plate 6. The top end of the threaded rod 801 is fixedly connected with a transmission wheel 802. A fixed rack 803 is meshed and transmitted on one side of the transmission wheel 802. The fixed rack 803 is fixedly connected with the inner wall of the processing seat 5. A movable block 804 is threadedly connected to the outer wall of the threaded rod 801. One end of the movable block 804 is fixedly connected with a chute rod 805.

[0030] A T-shaped head 806 is slidably fitted inside the inner wall of the chute rod 805. An L-shaped rod 807 is rotatably connected to the outer end of the T-shaped head 806. One side of the upper end of the L-shaped rod 807 is rotatably connected to the push plate 6. A connecting rod 808 is rotatably connected to the upper end of the L-shaped rod 807. The other end of the connecting rod 808 is rotatably connected to the moving block 701. When the push plate 6 continues to move, under the action of the fixed rack 803, the threaded rod 801 connected to the transmission wheel 802 rotates, causing the threaded rod 801 to drive the chute rod 805 connected to the movable block 804 to move upward. The chute rod 805 can drive the L-shaped rod 807 connected to the T-shaped head 806 to rotate. The other end of the L-shaped rod 807 drives the connecting rod 808 to rotate, and the connecting rod 808 drives the plastic cup processing plate 7 connected to the moving block 701 to move downward, pressing the disposable plastic cup 302 below, causing the water sample inside to be discharged and separated by the mesh plate 501. The L-shaped rod 807 can use the lever principle to achieve labor-saving pressurization.

[0031] As Figure 8 shown, two U-shaped handles 901 are slidably fitted symmetrically on the outside of the material receiving seat 9. One end of the U-shaped handle 901 is fixedly connected to a spring 902, and the other end of the spring 902 is fixedly connected to the material receiving seat 9. The two ends of the other side of the U-shaped handle 901 are movably inserted into the inner wall of the jack 503. When it is necessary to take out the disposable plastic cup 302 in the material receiving seat 9, by holding the two U-shaped handles 901, the two ends of the U-shaped handles 901 are removed from the jack 503, and the material receiving seat 9 can be taken out.

[0032] Working principle: When it is necessary to detect the pollution of the water sample, first place the treated water sample in the disposable plastic cup 302 and place the disposable plastic cup 302 in the placement groove 301 on the placement plate 3. The test chamber body 1 simulates the environment of low air pressure, temperature and humidity to detect the pollutants in the water sample; After the detection is completed, the motor 603 drives the connected lead screw 602 to rotate, causing the lead screw 602 to drive the slider 601 to move. Then the slider 601 will drive one side of the connected push plate 6. At this time, the contact rod 604 on the push plate 6 will not contact the contact plate 403; Then, under the action of the tension spring 304, the grooved rod 303 will be driven to move, causing the grooved rod 303 to drive the connected placement plate 3 to move outward, so that the disposable plastic cup 302 above will fall onto the mesh plate 501 in the processing seat 5 through the material guide seat 2. Since the mesh plate 501 is arranged in an inclined structure, the disposable plastic cup 302 will slide under the plastic cup processing plate 7. When the push plate 6 resets, the contact rod 604 on the push plate 6 will contact and squeeze the contact plate 403, causing the universal joint 401 connected to the contact plate 403 to rotate, so that the universal joint 401 drives the connected U-shaped rod 402 to rotate, causing the two ends of the U-shaped rod 402 to slide in the two grooved rods 303, thereby driving the two placement plates 3 to automatically move closer and reset; Then, when the push plate 6 continues to move, under the action of the fixed rack 803, the threaded rod 801 connected to the transmission wheel 802 will rotate, causing the threaded rod 801 to drive the chute rod 805 connected to the movable block 804 to move upward, so that the chute rod 805 can drive the L-shaped rod 807 connected to the T-shaped head 806 to rotate, causing the other end of the L-shaped rod 807 to drive the connecting rod 808 to rotate, so that the connecting rod 808 drives the plastic cup processing plate 7 connected to the moving block 701 to move downward, pressing the disposable plastic cup 302 below, so that the internal water sample is discharged and separated through the mesh plate 501; Then, when the push plate 6 continues to move, the flattened disposable plastic cup 302 will be pushed onto the opening plate 502 and fall into the receiving seat 9 through the opening plate 502 for collection. When it is necessary to take out the disposable plastic cup 302 in the receiving seat 9, by holding the two U-shaped handles 901, the two ends of the two U-shaped handles 901 are removed from the jacks 503, so that the receiving seat 9 can be taken out, and then the valve 504 is opened to discharge the water sample in the processing seat 5.
