Description

Technical Field

[0001] This invention relates to the field of temperature and humidity monitoring technology, specifically a temperature and humidity early warning monitoring device for greenhouse environments. Background Technology

[0002] Temperature and humidity control in greenhouses is crucial for crop growth. Different crops have specific requirements for temperature and humidity at different growth stages. Inappropriate temperature and humidity can lead to problems such as reduced seed germination rate, slow plant growth, and increased pests and diseases.

[0003] Greenhouses are relatively enclosed growing environments formed by plastic film and are quite tall. When monitoring temperature and humidity, there are significant differences in temperature and humidity at different heights inside the greenhouse. For example, in winter, under good sunlight conditions, the temperature at the top of the greenhouse near the film is higher, while the temperature near the ground is significantly lower than the top temperature. Humidity distribution also varies at different heights. Existing greenhouse temperature and humidity monitoring systems cannot monitor the temperature and humidity at different heights inside the greenhouse, and therefore cannot provide comprehensive data on the internal temperature and humidity of the greenhouse.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting up a sampling tube and a folding assembly, the height of the bottom of the sampling tube is adjusted to sample the air at different heights in the greenhouse, and the air samples at the corresponding heights are sent to the testing mechanism for temperature and humidity testing. Before testing, the upper end of the sampling tube is connected to the exhaust assembly to exhaust the residual air in the sampling tube, thereby ensuring that the air sent to the testing mechanism is an air sample at the corresponding height in the greenhouse, and ensuring the accuracy of the temperature and humidity data obtained. At the same time, combined with the walking mechanism set at the top, the testing box is controlled to move back and forth along the layout direction of the greenhouse, thereby realizing the sampling and testing of the overall temperature and humidity in the greenhouse. The temperature and humidity data model in the greenhouse is constructed by combining the data obtained from the sampling and testing, so as to facilitate the intuitive understanding of the temperature and humidity data at different heights and different parts in the greenhouse.

[0015] (2) By setting guide rail one and guide rail two, and simultaneously sliding a snap-fit ​​bracket on the fixed frame, the end of the control rod is controlled by the translation cylinder to cooperate with guide rail one or guide rail two. When the end of the control rod cooperates with guide rail one, the control component one drives the control rod to move along guide rail one, thereby causing the end of the sampling tube to bend towards the venting component. Then, the venting component removes the air in the sampling tube, avoiding additional air interference with the subsequent detection mechanism. When the end of the control rod cooperates with guide rail two, the control component two drives the control rod to move along guide rail two, thereby causing the end of the sampling tube to point towards the detection mechanism, thus facilitating the docking of the detection mechanism and the end of the sampling tube, delivering air at a specific height into the detection mechanism for temperature and humidity detection.

[0016] (3) By setting up a drying component, combined with the exhaust fan at the bottom of the test box, hot air is generated when pumping air into the test box, thereby venting the air in the test box and restoring the initial temperature and humidity data in the test box. When the exhaust fan is venting air, an automatic control switch valve can be set at the lower end of the sampling tube in advance to close the sampling tube. Then, when the exhaust fan in the test box is venting air, the air enters through the air inlet between the heating plate and the test box, and the air that enters is pre-treated by the moisture absorption box.

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0031] like Figures 1-3As shown, a greenhouse environmental temperature and humidity early warning monitoring device includes a detection box 1, which is suspended from the top of the greenhouse. A sampling tube 2 is connected to the bottom of the detection box 1, extending into the inside of the detection box 1. A steering mechanism 4 is connected to one end of the sampling tube 2 inside the detection box 1. An emptying component 5 and a detection mechanism 6 are provided inside the detection box 1 corresponding to the steering mechanism 4. The steering mechanism 4 drives the end of the sampling tube 2 to sequentially engage with the emptying component 5 and the detection mechanism 6. A folding component is provided at the bottom of the detection box 1, allowing the bottom of the sampling tube 2 to be adjusted via the folding component. The detection box 1 is equipped with a walking mechanism 8 at its top, which allows it to move and detect along the greenhouse. The folding assembly includes a snap-fit ​​slide rail 23 on the lower side wall of the detection box 1. Multiple sets of snap-fit ​​slide rails 23 are provided. A sliding rod 21 is slidably snapped into the snap-fit ​​slide rail 23. An abutment wheel 22 is installed on the sliding rod 21. A horizontal cylinder 24 is horizontally connected to the sliding rod 21. The sampling tube 2 is wound around the abutment wheel 22. A clamping wheel 25 is symmetrically arranged in the middle of the detection box 1. The other end of the sampling tube 2 is clamped and installed between the clamping wheels 25.

[0032] Specifically, by setting up sampling tube 2 and folding components, the height of the bottom of sampling tube 2 is adjusted to sample air at different heights within the greenhouse. The air samples at these heights are then sent to the detection mechanism 6 for temperature and humidity testing. Before testing, the upper end of sampling tube 2 is connected to the venting component 5 to remove any residual air, ensuring that the air sent to the detection mechanism 6 is a sample from the corresponding height within the greenhouse, thus guaranteeing the accuracy of the obtained temperature and humidity data. Simultaneously, the traveling mechanism 8 at the top controls the detection box 1 to move back and forth along the greenhouse's layout, thereby sampling and testing the overall temperature and humidity within the greenhouse. The data obtained from these sampling tests is used to construct a temperature and humidity data model of the greenhouse, facilitating a direct understanding of the temperature and humidity data at different heights and locations within the greenhouse.

[0033] More specifically, by setting up multiple sets of snap-fit ​​slide rails 23 and sliding rods 21, the horizontal cylinder 24 drives the sliding rods 21 to move back and forth along the snap-fit ​​slide rails 23. With the cooperation of the abutment wheel 22, the height of the end of the sampling tube 2 in the greenhouse is adjusted, thereby realizing the sampling and detection of temperature and humidity data at different heights.

[0034] It should be noted that sampling tube 2 uses a flexible tube with an embedded spiral steel wire to prevent the tube from becoming blocked when folded, thus ensuring smooth airflow during sampling.

[0035] Furthermore, such as Figure 2 , Figure 4 , Figure 5As shown, the steering mechanism 4 includes a fixed frame 40 connected to the inside of the detection box 1. The sampling tube 2 passes through the fixed frame 40 and extends to the upper side of the detection box 1. A snap-fit ​​bracket 42 is slidably mounted on the fixed frame 40. A translation cylinder 41 is provided between the bottom of the snap-fit ​​bracket 42 and the fixed frame 40. Guide rail 1 45 and guide rail 2 46 are respectively provided on both sides of the inner wall of the detection box 1. The sampling tube 2 is located between guide rail 1 45 and guide rail 2 46. Multiple sets of control rods 43 are distributed and installed between 46. Each control rod 43 is equipped with a clamping roller 44 that cooperates with the outer wall of the sampling tube 2. A connecting rope 431 is provided between the ends of the multiple sets of control rods 43 away from the clamping roller 44. A mating ring 430 is provided on the control rod 43. The mating ring 430 is engaged with the snap-fit ​​bracket 42. The control rods 43 are symmetrically arranged on both sides of the sampling tube 2. A control component 48 is provided in cooperation with the first guide rail 45, and a control component 49 is provided in cooperation with the second guide rail 46.

[0036] Specifically, in order to achieve the switching and docking of sampling tube 2 with venting component 5 and detection mechanism 6, guide rail 1 45 and guide rail 2 46 are set, and a snap-fit ​​bracket 42 is slidably set on the fixed frame 40. Using snap-fit ​​bracket 42 and mating ring 430 on control rod 43, combined with translation cylinder 41, the end of control rod 43 is controlled to cooperate with guide rail 1 45 or guide rail 2 46. When the end of control rod 43 cooperates with guide rail 1 45, control component 1 48 drives control rod 43 to move along guide rail 1 45, thereby causing the end of sampling tube 2 to bend towards venting component 5. Then, venting component 5 removes the air in sampling tube 2 to avoid additional air interference with subsequent detection by detection mechanism 6. When the end of the control rod 43 engages with the guide rail 46, the control component 49 drives the control rod 43 to move along the guide rail 46, thereby causing the end of the sampling tube 2 to point towards the detection mechanism 6. This facilitates the docking of the detection mechanism 6 and the end of the sampling tube 2, allowing air at a specific height to be delivered into the detection mechanism 6 for temperature and humidity detection.

[0037] Furthermore, such as Figures 5-7As shown, the control component 48 includes a mounting bracket 481 connected to the side wall of the detection box 1. A motor 482 is mounted on the mounting bracket 481. A swing frame 480 is mounted on the output shaft of the motor 482. A swing cylinder 483 is mounted on the swing frame 480. A mating frame 484 is connected to the swing cylinder 483. A mating rod 47 is mounted on the uppermost control rod 43. The control component 49 includes a mounting bracket 490 fixedly connected to the side wall of the detection box 1. A lifting cylinder 493 is mounted on the mounting bracket 490. A lifting frame 491 is mounted on the output shaft of the lifting cylinder 493. A mating frame 494 is horizontally slidably mounted on the lifting frame 491. A cylinder 492 is mounted on the lifting frame 491. The output shaft of the cylinder 492 is connected to the mating frame 494.

[0038] Specifically, when the end of the control rod 43 aligns with the guide rail 45, the swing cylinder 483, the mating frame 484, and the mating rod 47 of the upper control rod 43 work together. Combined with the swing frame 480 and the motor 482, the control rod 43 moves along the guide rail 45, causing the end of the sampling tube 2 to bend towards the venting assembly 5. The venting assembly 5 then vents the sampling tube 2, preventing residual air from affecting the accuracy of the detection mechanism 6. When the end of the control rod 43 aligns with the guide rail 46, the cylinder 492, the mating frame 494, and the mating rod 47 of the control rod 43 work together. Combined with the lifting cylinder 493, the control rod 43 moves up and down along the guide rail 46, causing the end of the sampling tube 2 to point towards the detection mechanism 6, facilitating subsequent temperature and humidity detection.

[0039] Furthermore, such as Figure 3 , Figure 4 As shown, the venting assembly 5 includes a venting pipe 50 disposed on the side wall of the detection box 1. The venting pipe 50 is inserted into the side wall of the detection box 1. A push-pull cylinder 52 is disposed inside the detection box 1. The push-pull cylinder 52 is connected to the end of the venting pipe 50. A connection interface 53 is disposed on one side of the venting pipe 50 inside the detection box 1. The other end of the venting pipe 50 is connected to a venting fan 51.

[0040] Specifically, when the end of the sampling tube 2 points to the venting component 5, the push-pull cylinder 52 drives the venting tube 50 to connect with the end of the sampling tube 2, and the venting fan 51 is used to vent all the residual air in the sampling tube 2. Then, the sampling tube 2 is connected to the detection mechanism 6 to perform temperature and humidity detection.

[0041] Furthermore, such as Figure 2 , Figure 8 , Figure 9As shown, the detection mechanism 6 includes a detection box 60 fixedly installed inside the detection box 1. The bottom of the detection box 60 is provided with a second interface 65. An exhaust fan 66 is provided inside the second interface 65. An exhaust pipe 63 is provided on the side of the detection box 60 and extends to the outside of the detection box 1. A temperature sensor 61 and a humidity sensor 62 are provided on the detection box 60. A second lifting cylinder 64 is provided on the detection box 60. The output shaft of the second lifting cylinder 64 passes through the detection box 60 and is connected to the side wall of the second interface 65.

[0042] Specifically, when the end of the sampling tube 2 points to the docking interface 65 at the bottom of the detection mechanism 6, the lifting cylinder 64 drives the docking interface 65 to move down, so that the ends of the sampling tube 2 are connected to each other. At this time, the exhaust fan 66 sends the air at a specific height in the greenhouse into the detection box 60, and the temperature sensor 61 and humidity sensor 62 are used for detection to obtain the temperature and humidity data at the corresponding height.

[0043] Furthermore, such as Figure 2 , Figure 8 As shown, a drying assembly 7 is also provided between the detection box 60 and the detection box 1. The drying assembly 7 includes a heating plate 70 inserted between the detection box 60 and the detection box 1. The heating plate 70 is hollow and has heating wires 71 evenly distributed on its surface. An air inlet is provided at the insertion position between the detection box 1 and the heating plate 70. A moisture-absorbing box 72 is provided at the air inlet. A push-pull handle 73 is provided on the heating plate 70.

[0044] Specifically, to avoid the air remaining in the detection chamber 60 from previous tests affecting subsequent tests, a drying component 7 is set up. Combined with the exhaust fan 66 at the bottom of the detection chamber 60, hot air is generated when the fan pumps air into the detection chamber 60, thereby venting the air in the detection chamber 60 and restoring the initial temperature and humidity data in the detection chamber 60. When the exhaust fan 66 is evacuating air, an automatically controlled switch valve can be set at the lower end of the sampling tube 2 to close the sampling tube 2. Subsequently, when the exhaust fan 66 in the detection box 1 evacuates air, the air enters through the air inlet between the heating plate 70 and the detection box 1, and the air that enters has been dehumidified in advance by the dehumidification box 72.

[0045] Furthermore, such as Figure 2 , Figures 10-12As shown, the walking mechanism 8 includes a mounting shaft 81 disposed on the top of the detection box 1. A walking steel wire 80 is installed on the top of the greenhouse. An obstacle block 84 is sleeved on the walking steel wire 80 and fixedly connected to the top of the greenhouse. A connecting cylinder 82 is sleeved on the mounting shaft 81. A torsion spring is disposed between the connecting cylinder 82 and the mounting shaft 81. A suspension assembly 83 is disposed on the connecting cylinder 82. The suspension assembly 83 includes components disposed on the connecting cylinder 82. The semi-circular frame 831 has an arc-shaped locking groove 832 inside, an arc-shaped cylinder 833 installed in the arc-shaped locking groove 832, and a mating frame 834 slidably installed in the arc-shaped locking groove 832. The arc-shaped cylinder 833 is connected to the mating frame 834. A lifting motor 835 is provided at the bottom of the mating frame 834. The lifting motor 835 is connected to a traveling wheel 836, and the traveling wheel 836 abuts against the upper surface of the traveling steel wire 80.

[0046] Furthermore, such as Figure 11 , Figure 12 As shown, the suspension assembly 83 has two sets on both sides of the traveling steel wire 80. The top of the semi-circular frame 831 is provided with a vertical frame 837. The two ends of the vertical frame 837 are provided with abutment posts 838. The clearance block 84 is provided with an inclined sliding groove 842 that cooperates with the abutment post 838. The clearance block 84 is also provided with an inclined surface 841. The inclined sliding groove 842 is provided on the inclined surface 841.

[0047] Specifically, by setting up a walking mechanism 8 to drive the detection box 1 to continuously sample along the walking steel wire 80, a three-dimensional temperature and humidity data model of the greenhouse can be constructed, making it easier to intuitively understand the temperature and humidity data of the greenhouse. In order to avoid being blocked by the avoidance block 84 during walking, an inclined surface 841 is set on the avoidance block 84, and an inclined groove 842 is set on the inclined surface 841. When the abutment post 838 in the suspension assembly 83 cooperates with the inclined groove 842, the suspension assembly 83 will disengage from the walking steel wire 80 under the guiding action of the inclined groove 842. After passing the avoidance block 84, the suspension assembly 83 returns to the initial position under the action of the torsion spring. Combined with the lifting motor 835, the upper surface between the walking wheel 836 and the walking steel wire 80 continues to contact each other, thereby continuing the walking detection.

[0048] Furthermore, a counterweight 20 is fitted onto the lower end of the sampling tube 2.

[0049] Specifically, the counterweight 20 at the bottom of the sampling tube 2 can ensure that the sampling tube 2 can be smoothly raised and lowered when the folding component is working, and at the same time ensure the stability of the bottom of the sampling tube 2 when it is driven by the walking mechanism 8.

[0050] The working principle of this invention embodiment is as follows: like Figures 1-12As shown, by setting up sampling tube 2 and folding components, the height of the bottom of sampling tube 2 can be adjusted to sample air at different heights within the greenhouse. The air samples at these heights are then sent to the detection mechanism 6 for temperature and humidity testing. Before testing, the upper end of sampling tube 2 is connected to the venting component 5 to remove any residual air from the sampling tube 2, ensuring that the air sent to the detection mechanism 6 is a sample from the corresponding height within the greenhouse, thus guaranteeing the accuracy of the obtained temperature and humidity data. Simultaneously, the traveling mechanism 8 at the top controls the detection box 1 to move back and forth along the greenhouse's layout, thereby sampling and testing the overall temperature and humidity within the greenhouse. The data obtained from the sampling and testing is used to construct a temperature and humidity data model within the greenhouse, facilitating a direct understanding of the temperature and humidity data at different heights and locations within the greenhouse. By setting multiple sets of snap-fit ​​slide rails 23 and sliding rods 21, and using a horizontal cylinder 24 to drive the sliding rods 21 to move back and forth along the snap-fit ​​slide rails 23, the height of the sampling tube 2 end inside the greenhouse is adjusted with the cooperation of the abutment wheel 22, thereby realizing the sampling and detection of temperature and humidity data at different heights. In order to realize the switching and docking of the sampling tube 2 with the venting component 5 and the detection mechanism 6, guide rail 1 45 and guide rail 2 46 are set, and a snap-fit ​​frame 42 is slidably set on the fixed frame 40. Using the snap-fit ​​frame 42 and the mating ring 430 on the control rod 43, combined with the translation cylinder 41, the end of the control rod 43 is controlled to cooperate with the guide rail 1 45 or the guide rail 2 46. When the end of the control rod 43 cooperates with the guide rail 1 45, the control component 1 48 drives the control rod 43 to move along the guide rail 1 45, thereby causing the end of the sampling tube 2 to bend towards the venting component 5. Then, with the cooperation of the venting component 5, the air in the sampling tube 2 is vented away, avoiding additional air interference with the subsequent detection by the detection mechanism 6. When the end of control rod 43 engages with guide rail 46, control component 49 moves control rod 43 along guide rail 46, causing the end of sampling tube 2 to point towards detection mechanism 6. This facilitates docking between detection mechanism 6 and the end of sampling tube 2, allowing air at a specific height to be delivered into detection mechanism 6 for temperature and humidity detection. When the end of control rod 43 engages with guide rail 45, swing cylinder 483, mating frame 484, and mating rod 47 on the upper control rod 43 engage with swing frame 480 and motor 482, moving control rod 43 along guide rail 45. This causes the end of sampling tube 2 to bend towards venting component 5, venting sampling tube 2 and preventing residual air in sampling tube 2 from affecting the accuracy of detection mechanism 6.When the end of the control lever 43 aligns with the guide rail 46, the cylinder 492, the mounting bracket 494, and the mounting rod 47 of the control lever 43 work together, and the lifting cylinder 493 moves the control lever 43 up and down along the guide rail 46, thus controlling the end of the sampling tube 2 to point towards the detection mechanism 6, facilitating subsequent temperature and humidity detection. When the end of the sampling tube 2 points towards the docking interface 65 at the bottom of the detection mechanism 6, the lifting cylinder 64 moves the docking interface 65 down, aligning the ends of the sampling tube 2. At this time, the exhaust fan 66 delivers air at a specific height inside the greenhouse into the detection box 60, where it is detected by the temperature sensor 61 and the humidity sensor 62, thus obtaining the temperature and humidity data at the corresponding height. To prevent residual air from previous tests from affecting subsequent tests in the testing chamber 60, a drying component 7 is installed. Combined with the exhaust fan 66 at the bottom of the testing chamber 60, hot air is generated when pumping air into the testing chamber 60, thus purging the air inside and restoring the initial temperature and humidity data. During exhaust, an automatically controlled valve at the lower end of the sampling tube 2 can be pre-operated to close the sampling tube 2. Air then enters the testing chamber 1 through the air inlet between the heating plate 70 and the testing chamber 1, and is pre-treated by the moisture-absorbing box 72. A walking mechanism 8 drives the testing chamber 1 along the walking steel wire 80 for continuous sampling, thereby constructing a three-dimensional temperature and humidity data model of the greenhouse, facilitating a direct understanding of the greenhouse's temperature and humidity data. To prevent obstruction by the avoidance block 84 during movement, an inclined surface 841 is provided on the avoidance block 84, and an inclined groove 842 is provided on the inclined surface 841. When the abutment post 838 in the suspension assembly 83 cooperates with the inclined groove 842, the suspension assembly 83 will disengage from the walking wire 80 under the guiding action of the inclined groove 842. After passing the avoidance block 84, the suspension assembly 83 returns to its initial position under the action of the torsion spring. Combined with the lifting motor 835, the upper surface between the walking wheel 836 and the walking wire 80 continues to contact each other, thereby continuing the walking detection.
