Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a device for monitoring the environment of a vegetable greenhouse. Background Art

[0002] A vegetable greenhouse is a modern agricultural facility, an artificial structure usually composed of plastic film, steel frame or bamboo frame, used to cover the land to form a relatively closed small environment, used to create suitable environmental conditions for vegetables, so as to extend the growth cycle of vegetables, increase yield and improve quality.

[0003] In the process of vegetable greenhouse cultivation, monitoring of soil temperature and humidity is very important. Soil temperature and humidity are one of the key factors affecting vegetable growth. Appropriate temperature and humidity conditions can provide a good environment for plant root growth and nutrient absorption, thereby promoting the healthy growth of vegetables and improving yield and quality. Therefore, real-time and accurate monitoring of soil temperature and humidity is of great significance for optimizing the vegetable planting environment and realizing precision agricultural management.

[0004] When monitoring soil temperature and humidity, professional soil temperature and humidity sensors are usually used. These sensors can accurately measure the temperature and humidity data in the soil and transmit the information to the monitoring system for growers' reference and analysis. However, when installing and using soil temperature and humidity sensors, it is necessary to pay attention to the soil. There should be no hard objects such as stones, bricks, and glass fragments mixed in. These hard objects may damage the sensor during insertion into the soil or long-term use, affecting the accuracy and service life of the sensor, and even causing the sensor to malfunction. For example, stones may scratch the sensor probe, making it unable to accurately measure the temperature and humidity of the soil; while larger hard objects may hinder the normal insertion of the sensor, resulting in inaccurate monitoring data.

[0011] Preferably, the sealing cover is provided with a plurality of water diversion grooves, and all the water diversion grooves are distributed on the outer wall of the sealing cover in a linear array.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets an elastic component. When the detection probe is inserted into the target area, if it encounters a hard block in the soil, in order to prevent the detection probe from being damaged, the detection probe will automatically move upward to compress the elastic component to avoid the hard block. This helps to avoid damage to the detection probe caused by the hard block. If the detection probe still cannot break through the hard block after reaching the maximum clearance distance, then under the action of the hard block, the detection probe will drive the sliding plate to slide along the cavity through the elastic component and the barrel, thereby bypassing the hard block; on the one hand, the avoidance of the hard object by the detection probe not only helps to prevent the hard object from causing damage to the detection probe, but also helps the detection probe to smoothly descend to the predetermined position, thereby ensuring the smooth progress of the detection work.

[0017] 2. The present invention sets an electromagnet. After the detection probe moves upward to a specified distance, the electromagnet is energized to generate magnetism. After the electromagnet generates magnetism, it will adsorb the push rod. Then the electric telescopic rod is controlled to start. By controlling one of the electric telescopic rods to contract and pull the electromagnet, the electromagnet drives the push rod to move, and the push rod drives the sliding plate to slide. The sliding plate drives the detection probe to avoid hard objects, which helps to prevent the detection probe from being difficult to move.

[0018] 3. The present invention arranges the push rod and the push block, and when the sealing cover moves upward, the push rod will be driven to move upward. The push rod will contact the guide surface on the push block when it moves upward, and the sealing cover will be driven to rotate under the action of the guide surface, so that the detection probe rotates. The rotating action of the detection probe is helpful to help it break through the hard block. During the rotation process, the detection probe will drive the ring to rotate, and the ring will drive the rotating ring to rotate through the rod. The annular ring drives the circular hole to rotate and gradually overlap with the water outlet, so that the liquid can flow out at this time to soak the hard block.

DETAILED DESCRIPTION

[0029] 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 described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] Application scenarios: When monitoring soil temperature and humidity, professional soil temperature and humidity sensors are usually used. These sensors can accurately measure the temperature and humidity data in the soil and transmit the information to the monitoring system for growers' reference and analysis. However, when installing and using soil temperature and humidity sensors, it should be noted that the soil should not be mixed with hard objects such as stones, bricks, and glass fragments. These hard objects may damage the sensor when it is inserted into the soil or during long-term use, affecting the accuracy and service life of the sensor, and even causing the sensor to malfunction. For example, stones may scratch the sensor probe, making it unable to accurately measure the temperature and humidity of the soil; and larger hard objects may hinder the normal insertion of the sensor, resulting in inaccurate monitoring data.

[0031] like Figures 1 to 9 A vegetable greenhouse planting environment monitoring device shown in the figure comprises a base frame 1, a monitoring rod 2 is fixedly mounted on the base frame 1, a mounting frame 3 is fixedly mounted on the outer wall of the monitoring rod 2, a monitoring component is arranged on the mounting frame 3, and a data collector 4 is fixedly mounted on the outer wall of the monitoring rod 2; A receiving assembly is symmetrically arranged on the base frame 1, and a lower pressure plate 5 is slidably arranged between two groups of receiving assemblies. A lower pressure cylinder 6 is fixedly installed on the bottom of the lower pressure plate 5. A slot 7 for the lower pressure cylinder 6 to pass through is provided on the base frame 1, and a disc 8 is fixedly installed on the lower pressure cylinder 6. A cavity is provided inside the disc 8, and a cross groove 9 is provided on the disc 8. The cross groove 9 is connected with the cavity, and a sliding disc 10 is slidably connected inside the cross groove 9. A connecting cylinder 11 is fixedly installed on the bottom of the sliding disc 10, and a detection probe 12 is slidably connected inside the connecting cylinder 11. A sleeve barrel 13 is fixedly installed on the top of the disc 8, and an elastic assembly is provided between the detection probe 12 and the sleeve barrel 13.

[0032] It should be understood that the monitoring device is installed at a pre-selected location with loose soil in the vegetable greenhouse, and the monitoring component is used to monitor the environment in the greenhouse in real time to ensure that the planting environment is suitable. The data collector 4 is responsible for collecting and processing the data collected by all sensors, so that the operator can make corresponding adjustments to the environmental parameters based on these data.

[0033] At the same time, the lower pressing plate 5 is pushed downward by controlling the receiving assembly, and the movement of the lower pressing plate 5 drives the lower pressing cylinder 6 to slide toward the target area. During the movement of the lower pressing cylinder 6, it drives the sliding plate 10 to slide downward through the disc 8, and the movement of the sliding plate 10 further drives the connecting cylinder 11 to slide downward, and finally the connecting cylinder 11 drives the detection probe 12 to be inserted into the target soil area, and the soil temperature and humidity sensor to be used is installed on the detection probe 12 for use; During the process of inserting the detection probe 12 into the target area, if it encounters a hard block in the soil, in order to prevent the detection probe 12 from being damaged, the detection probe 12 will automatically move upward to compress the elastic component to avoid the hard block, which helps to avoid damage to the detection probe 12 caused by the hard block. If the detection probe 12 still cannot break through the hard block after reaching the maximum clearance distance, then under the action of the hard block, the detection probe 12 will drive the sliding plate 10 to slide along the cavity through the elastic component and the barrel 13, thereby bypassing the hard block; on the one hand, the avoidance of the hard object by the detection probe 12 not only helps to prevent the hard object from causing damage to the detection probe 12, but also helps the detection probe 12 to smoothly descend to the predetermined position, thereby ensuring the smooth progress of the detection work.

[0034] As a further implementation scheme of the present invention, the receiving assembly includes a mounting rod 14, which is fixedly connected to the top of the base frame 1, a fixing plate 15 is fixedly installed on the top of the mounting rod 14, a sliding seat 16 is symmetrically fixedly connected to the end of the fixing plate 15, a hydraulic rod 17 is fixedly installed on the top of the fixing plate 15, and the telescopic end of the hydraulic rod 17 passes through the fixing plate 15 and is fixedly connected to a lower sliding frame 18, a sliding rod 19 is symmetrically fixedly connected to the lower sliding frame 18, and the two sliding rods 19 are respectively slidably connected to the two sliding seats 16, and the lower pressure plate 5 is fixedly connected to the sliding rod 19.

[0035] It should be understood that by controlling the hydraulic rod 17 to start the push-out, the hydraulic rod 17 will push the lower slide frame 18 to move, the lower slide frame 18 will drive the slide rod 19 to move, the slide rod 19 will slide downward inside the slide seat 16 and push the lower pressure plate 5 to move, thereby facilitating the detection probe 12 to smoothly enter the soil in the target area.

[0036] As a further embodiment of the present invention, the elastic component includes a connecting rod 20 and a connecting port 21, the connecting port 21 is opened on the disc 8, the connecting rod 20 is fixedly connected to the detection probe 12, the top end of the connecting rod 20 is fixedly connected with a sealing cover 22, the diameter of the sealing cover 22 is equal to that of the connecting port 21, and a spring 23 is fixedly installed between the sealing cover 22 and the barrel 13.

[0037] It should be understood that when the detection probe 12 moves upward to make way when encountering a hard object, it will drive the connecting rod 20 to move upward, and the connecting rod 20 will drive the sealing cover 22 to move upward. As the connecting rod 20 rises, the sealing cover 22 will also be driven to move upward, and finally move out from the inside of the connecting port 21. In this process, the rise of the sealing cover 22 will exert pressure on the spring 23, compressing the spring 23. The compression of the spring 23 provides additional space for the rise of the sealing cover 22, ensuring that it can move smoothly with the upward movement of the detection probe 12, thereby adapting to the change in the trajectory of the probe when avoiding the hard block.

[0038] As a further implementation scheme of the present invention, a plurality of electric telescopic rods 24 are fixedly connected inside the cross slot 9, the telescopic ends of the electric telescopic rods 24 are fixedly connected to electromagnets 25, and a push rod 26 is fixedly connected to the outer wall of the sliding plate 10, and the push rod 26 cooperates with the electromagnet 25.

[0039] It should be understood that in the above example, it is described that the detection probe 12 can bypass the hard block under the action of force by giving way. However, in the process of the detection probe 12 bypassing the hard block, it may be difficult for the detection probe 12 to move, which will cause damage to the detection probe 12. Therefore, after the detection probe 12 moves upward to a specified distance, the electromagnet 25 is energized to generate magnetism. The electromagnet 25 is energized by a battery. After the electromagnet 25 generates magnetism, it will adsorb the push rod 26, and then the electric telescopic rod 24 is controlled to start. By controlling one of the electric telescopic rods to contract and pull the electromagnet 25, the electromagnet 25 drives the push rod 26 to move, and the push rod 26 drives the sliding plate 10 to slide. The sliding plate 10 will drive the detection probe 12 to avoid the hard object, which is beneficial to prevent the detection probe 12 from being difficult to move.

[0040] As a further embodiment of the present invention, a water tank 27 is fixedly connected to the top of the disc 8 , a water pipe 28 is fixedly connected between the water tank 27 and the sleeve barrel 13 , and a plurality of water flow ports 29 are opened on the connecting tube 11 .

[0041] It should be understood that in the above example, the electromagnet 25 is set to assist in driving the detection probe 12 to move. However, in actual application, there may be a situation where the pin is inserted into the soil but does not penetrate. At this time, pulling the detection probe 12 may easily cause the detection probe 12 to bend. Therefore, during the start-up of the hydraulic push rod, the water tank 27 is synchronously controlled to send water to the inside of the barrel 13 through the water pipe 28. Because, as the sealing cover 22 is moved out from the inside of the sealing port, the water flow entering the barrel 13 can enter the inside of the connecting tube 11 and discharge the liquid through the water outlet 29. In this process, if the detection probe 12 encounters The hard block found is of soil nature, and the soil is softened by adding an appropriate amount of water. On the one hand, the infiltration of liquid helps to make the hard soil block soft, so that with the assistance of the spring 23, the detection probe 12 can more easily pass through the soil block; on the second hand, if the probe still cannot penetrate the soil block, the wet bump can help guide the probe to avoid obstacles. On the third hand, if the probe still cannot move after the soil is moistened, this may mean that the obstacle encountered is not ordinary soil, and bypassing it by applying external force will affect the detection probe 12. In this case, the operator needs to be reminded to take other measures to avoid damage to the detection probe 12.

[0042] As a further embodiment of the present invention, a plurality of water diversion grooves 30 are provided on the sealing cover 22 , and all the water diversion grooves 30 are distributed on the outer wall of the sealing cover 22 in a linear array.

[0043] It should be understood that in order to verify whether the soil is moist enough for the detection probe 12 to penetrate under the thrust of the spring 23, we equip the sealing cover 22 with a water guide groove. As the sealing cover 22 moves upward, water will flow along the water guide groove toward the disc 8. The design of the water guide groove makes it gradually exposed as the sealing cover 22 moves upward, resulting in a gradual increase in water flow. This method of gradually increasing the water flow to soften the hard block is conducive to testing whether the detection probe 12 can successfully penetrate the soil block, and is conducive to preventing the occurrence of a situation where excessive water application affects the detection result of the detection probe 12.

[0044] As a further implementation scheme of the present invention, a pushing assembly is provided between the sealing cover 22 and the sleeve barrel 13, a rotating ring 31 is sleeved on the outer wall of the detection probe 12, the rotating ring 31 is slidably connected to the end of the connecting tube 11, and circular holes 32 are opened on the rotating ring 31. The number of circular holes 32 is the same as the water outlet 29. The bottom of the rotating ring 31 is fixedly connected to a sleeve ring 34 through a sleeve rod 33, and the sleeve ring 34 is fixedly connected to the outer wall of the detection probe 12.

[0045] It should be understood that after the sealing cover 22 moves upward to the specified position, the pushing assembly will push the sealing cover 22 to rotate, and the sealing cover 22 will drive the detection probe 12 to rotate through the connecting rod 20. The rotation of the detection probe 12 is helpful to help it break through the hard block. During the rotation process, the detection probe 12 will drive the ring 34 to rotate, and the ring 34 will drive the rotating ring 31 to rotate through the sleeve rod 33. The annular ring drives the circular hole 32 to rotate and gradually overlap with the water outlet 29, so that the liquid can flow out at this time to soak the hard block.

[0046] It should be further explained that the sleeve rod 33 includes a sliding tube and a sliding rod, and the sliding rod is slidably connected inside the sliding tube.

[0047] As a further implementation scheme of the present invention, the pushing assembly includes a pushing rod 35 and a pushing block 36. The pushing rod 35 is fixedly connected to the top of the sealing cover 22, and the pushing block 36 is fixedly installed on the inner bottom surface of the barrel 13. The pushing block 36 is provided with a guide surface, and the pushing rod 35 cooperates with the guide surface.

[0048] It should be understood that when the sealing cover 22 moves upward, the push rod 35 will be driven to move upward. The push rod 35 moves upward and contacts the guide surface on the push block 36. The sealing cover 22 is driven to rotate under the action of the guide surface, thereby rotating the detection probe 12.

[0049] As a further embodiment of the present invention, a plurality of insertion rods 37 are fixedly connected to the bottom of the disc 8, and all the insertion rods 37 are distributed in a circular array.

[0050] It should be understood that when the disc 8 moves downward, the insertion rod 37 will be driven to move downward, so that the insertion rod 37 is inserted into the soil, which is beneficial to fix the device.

[0051] As a further embodiment of the present invention, the monitoring component includes a light sensor, a carbon dioxide sensor and a wind speed sensor, and the light sensor, the carbon dioxide sensor and the wind speed sensor are fixedly connected to different positions of the mounting frame 3 respectively.

[0052] It should be understood that the environment in the greenhouse is monitored in real time through light sensors, carbon dioxide sensors and wind speed sensors to facilitate adjustments, and different sensors can be installed according to actual needs, which will not be elaborated in detail.

[0053] Working principle of the present invention: The monitoring device is installed at a pre-selected location with loose soil in the vegetable greenhouse, and the monitoring component is used to monitor the environment in the greenhouse in real time to ensure that the planting environment is suitable. The data collector 4 is responsible for collecting and processing the data collected by all sensors, so that the operator can make corresponding adjustments to the environmental parameters based on these data.

[0054] At the same time, the receiving assembly is controlled to push the lower pressing plate 5 to slide downward, and the movement of the lower pressing plate 5 drives the lower pressing cylinder 6 to slide toward the target area. During the movement of the lower pressing cylinder 6, it drives the sliding plate 10 to slide downward through the disc 8, and the movement of the sliding plate 10 further drives the connecting cylinder 11 to slide downward, and finally the connecting cylinder 11 drives the detection probe 12 to insert into the target soil area; During the process of inserting the detection probe 12 into the target area, if it encounters a hard block in the soil, in order to prevent the detection probe 12 from being damaged, the detection probe 12 will automatically move upward to compress the elastic component to avoid the hard block, which helps to avoid damage to the detection probe 12 caused by the hard block. If the detection probe 12 still cannot break through the hard block after reaching the maximum clearance distance, then under the action of the hard block, the detection probe 12 will drive the sliding plate 10 to slide along the cavity through the elastic component and the barrel 13, thereby bypassing the hard block; on the one hand, the avoidance of the hard object by the detection probe 12 not only helps to prevent the hard object from causing damage to the detection probe 12, but also helps the detection probe 12 to smoothly descend to the predetermined position, thereby ensuring the smooth progress of the detection work.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
