Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring devices, in particular to an environmental monitor for soilless cultivation. Background Art

[0002] Soilless culture refers to a cultivation method in which water, peat, forest leaf mold, vermiculite and other media are used as the substrate for the plant roots to fix the plants, so that the plant roots can directly contact the nutrient solution. The composition of the nutrient solution in soilless culture is easy to control and can be adjusted at any time. In places with suitable light and temperature but no soil, such as deserts, beaches, and deserted islands, as long as there is a certain amount of fresh water supply, it can be carried out. Soilless culture is divided into hydroponics, mist (air) culture and substrate culture according to the different cultivation media. Hydroponics refers to a cultivation method in which the plant roots are in direct contact with the nutrient solution without the use of a substrate. The earliest hydroponics was to immerse the plant roots in the nutrient solution for growth. This method will cause hypoxia, and in severe cases, cause the death of the roots. The hydroponic method often used is the nutrient film method, that is, a very thin layer of nutrient solution that continuously circulates through the crop roots, ensuring a continuous supply of water and nutrients to the crops, and a continuous supply of fresh oxygen to the roots. Soilless cultivation is usually carried out in a special culture room, and the environment in the culture room needs to be monitored to ensure the normal growth of the plants, including temperature, humidity, pH value of the nutrient solution, and plant diseases and pests.

[0003] Existing technologies usually use sensors to monitor various data. However, for larger culture rooms, the data monitored by sensors cannot represent the actual data at any location in the culture room. In addition, for the monitoring of pests and diseases, it is necessary to use camera technology to collect images. During this process, conventional cameras cannot accurately collect the conditions of plants in each area. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an environmental monitor for soilless cultivation to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Through the arrangement of the first rack and the second rack, the device can move horizontally and vertically, so that the monitoring range can be accurately distributed at any position in the culture room, thereby improving the monitoring effect. Through the cooperation of the moving component and the detection component, each time the detection component moves from one end of the first rack to the other end, the moving component travels a distance along the second rack, which facilitates the movement of the device along the room for monitoring.

[0005] In order to achieve the above-mentioned object, the present invention is implemented through the following technical solutions: an environmental monitor for soilless cultivation, comprising a slide rail, a first rack is provided on both sides of the slide rail, and mounting plates are fixed at both ends of the slide rail and the first rack, a detection assembly is installed on the surface of the slide rail, and the detection assembly includes a slide seat, a movable groove is opened on the slide seat corresponding to the position of the slide rail and the first rack, and the slide rail and the first rack slide through the movable groove of the slide seat, the slide rail is slidably engaged with the slide seat, a driving turntable is rotatably installed on the bottom of the slide seat through a bearing, and a vertical frame is fixed to the bottom of the driving turntable, A camera is installed inside the vertical frame, and a detector is fixed to the bottom of the vertical frame at the camera. A tube is provided at the bottom of the detector. Second racks are provided at both ends of the slide rail, and a moving component is provided on the surface of the second rack. The moving component includes a vertical plate, and a second gear is rotatably installed on one side surface of the vertical plate, and the second gear is meshed with the top of the second rack. A buckle frame is fixed to the bottom of the vertical plate, and the buckle frame is slidably buckled to the bottom of the second rack. Fixed plates are fixed at both ends of the second rack, and an annular chain is provided on the front of the vertical plate, and the slide is connected to the chain transmission.

[0006] Furthermore, the detection component also includes a first gear, and the first gear is rotatably installed at the bottom of the movable groove of the slide corresponding to the first rack passing through, and a motor that drives the first gear to rotate is installed on the outside of the slide, and the first gear is meshed with the bottom of the first rack.

[0007] Furthermore, a hose is fixed to the bottom of the detector, and the other end of the hose is fixedly connected to the cannula. A first electric push rod is fixed to the bottom of the detector, and the extended end of the first electric push rod is fixedly connected to the top of the cannula.

[0008] Furthermore, a temperature sensor is installed on one side of the vertical frame, and a humidity sensor is installed on the other side of the vertical frame, and a battery box is installed inside the sliding seat.

[0009] Furthermore, the moving assembly also includes a sprocket. Two sprockets are symmetrically mounted on the front of the vertical plate through bearings, and the chain is meshed and sleeved on the two sprockets. The sprocket on one side of the vertical plate is fixedly connected to the second gear on the back.

[0010] Furthermore, an inclined plate is provided on the front of the vertical plate, and the inclined plate is parallel to the chain of the lower layer of the vertical plate. Inclined blocks are fixed on both sides of the slide, and the inclined blocks are in sliding contact with the inclined surface of the inclined plate.

[0011] Furthermore, two groups of second electric push rods are fixed on the outer wall of the slide seat, and the directions of the second electric push rods are opposite. The extended ends of the second electric push rods are fixed with extrusion plates, and the extrusion plates are in extrusion contact with the front end of the inclined plate.

[0012] Furthermore, a sliding frame is provided at the bottom of the inclined plate, and a slider is slidably connected inside the sliding frame. The slider is fixedly connected to the bottom of the inclined plate, and a return spring is fixed between the slider and the inner wall of the sliding frame.

[0013] Furthermore, two spring telescopic rods are fixed at the bottom of the vertical plate at a position corresponding to the sliding frame, and the extended ends of the spring telescopic rods are fixedly connected to the sliding frame.

[0014] Furthermore, a transmission rod is fixed between the second gears at the top of the two second racks, and the sprocket is fixedly sleeved on the transmission rod.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention drives the first gear to rotate through a motor, the first gear engages with the first rack, and the slide slides along both sides of the slide rail, so that the detection component moves stably along the path of the first rack and the slide rail, and performs mobile monitoring of the culture area on the lower layer.

[0017] 2. After the movement is completed, the detection component of the present invention returns to its original path. The inclined plate first pops outward through the spring telescopic plate, and then returns to its original position through the reset spring inside the slide frame. Because the two second gears are connected by a transmission rod, when the detection component moves to one side, it will drive the moving components at both ends to move synchronously, and then the moving path of the detection component is set to be limited by the length of the slide rail, so that the plants in the culture room can be monitored back and forth.

[0018] 3. The present invention maintains the stability of the device during movement by sliding the buckle frame along the bottom of the second rack. During the movement of the inclined plate, the second electric push rod is shortened cooperatively, but the extrusion plate keeps the extrusion limit on the inclined plate, so that it cannot escape the extrusion effect on the chain.

[0019] 4. In the present invention, when the moving assembly approaches the second rack at one end, the inclined block will first contact the inclined surface of the inclined plate, and at the same time, the inclined plate will be pushed backward through the second electric push rod and the extrusion plate, and the detection assembly will continue to move backward to maintain the contact between the inclined block and the inclined plate. The spring telescopic plate will shrink after being squeezed, and the back of the inclined plate will be squeezed and contacted with the chain. Subsequently, as the detection assembly continues to move, the inclined plate slides along the slide frame through the bottom slider through the cooperation between the inclined block and the inclined surface of the inclined plate. Because the chain itself has a certain hardness, it will move synchronously with the inclined plate under the extrusion of the inclined plate, and the chain drives the sprocket to rotate counterclockwise, and the second gear connected to the sprocket will also rotate synchronously to engage with the second rack, driving the vertical plate, the first rack, the slide rail and the detection assembly to move a distance along the direction of the second rack.

[0020] 5. Compared with the prior art, the present invention enables the device to move horizontally and vertically through the arrangement of the first rack and the second rack, so that the monitoring range can be accurately distributed at any position in the culture room, thereby improving the monitoring effect. Through the cooperation between the moving component and the detection component, each time the detection component moves from one end of the first rack to the other end, the moving component travels a distance along the second rack, which facilitates the movement of the device along the room for monitoring.

When the device is used, the lengths of the first rack 11, the slide rail 1 and the second rack 3 are customized according to the length and width of the culture chamber, and the second rack 3 is fixed to the two ends of the culture chamber through the fixed plates 31 at both ends. The detection component 2 moves along the first rack 11 and the slide rail 1 to monitor the plants and environment on the path. When the detection component 2 moves to one end of the slide rail 1, it will cooperate with the moving component 4 on the second rack 3 to horizontally move the first rack 11, the slide rail 1 and the detection component 2 for a distance, thereby realizing the horizontal and vertical movement detection of the detection component 2.

[0032] In this embodiment, the detection component 2 also includes a first gear 29, and the slide 21 is rotatably installed with the first gear 29 at the bottom of the movable groove through which the first rack 11 passes, and a motor for driving the first gear 29 to rotate is installed on the outer side of the slide 21. The first gear 29 is meshed with the bottom of the first rack 11, and the first gear 29 is driven to rotate by the motor. The first gear 29 meshes with the first rack 11, and the slide 21 slides along both sides of the slide rail 1, so that the detection component 2 moves stably along the path of the first rack 11 and the slide rail 1, and performs mobile monitoring of the culture area in the lower layer.

[0033] In this embodiment, a hose 27 is fixed to the bottom of the detector 25, and the other end of the hose 27 is fixedly connected to the cannula 26. A first electric push rod 28 is fixed to the bottom of the detector 25, and the extended end of the first electric push rod 28 is fixedly connected to the top of the cannula 26. A temperature sensor 210 is installed on one side of the vertical frame 23, and a humidity sensor 211 is installed on the other side of the vertical frame 23. A battery box is installed inside the slide 21. When the detection component 2 moves to the upper end position of the plant culture solution, the cannula 26 is driven down by the first electric push rod 28. During this process, the hose 27 is unfolded to keep the cannula 26 connected to the detector 25. The cannula 26 is inserted into the culture solution, and the pH value in the culture solution is detected by the detector 25. The measuring instrument 25 is an existing detection equipment. It is very important to monitor the content of major elements such as nitrogen, phosphorus, potassium and other trace elements in the nutrient solution. Through sensing equipment such as pH sensors, the composition of the nutrient solution is monitored online, and the formula of the nutrient solution is adjusted in time to meet the needs of plants at different growth stages. The temperature, humidity and plant images in the moving area are collected through the temperature sensor 210, the humidity sensor 211 and the camera 24 to accurately grasp the precise values ​​of each area. In this structure, the battery box inside the slide 21 supplies power to various components. At the same time, a motor is also installed inside the slide 21 to drive the drive turntable 22 to rotate. Each time the detection component 2 moves to one end of the slide rail 1, the drive turntable 22 automatically turns to change the direction of the camera 24.

[0034] In this embodiment, the moving component 4 also includes a sprocket 43. Two sprockets 43 are symmetrically mounted on the front of the vertical plate 41 through bearings, and a chain 47 is meshed and sleeved on the two sprockets 43. The sprocket 43 on one side of the vertical plate 41 is fixedly connected to the second gear 42 on the back. A slanted plate 45 is provided on the front of the vertical plate 41, and the slanted plate 45 is parallel to the chain 47 on the lower layer of the vertical plate 41. Slanted blocks 212 are fixed on both sides of the slide 21, and the slanted blocks 212 are in sliding contact with the inclined surface of the slanted plate 45. Two groups of second electric push rods 213 are fixed on the outer wall of the slide 21, and the directions of the second electric push rods 213 are opposite. An extrusion plate 214 is fixed to the extended end of the second electric push rod 213, and the extrusion plate 214 is in contact with the front of the slanted plate 45. The ends are squeezed and contacted, a sliding frame 46 is provided at the bottom of the inclined plate 45, and a slider 49 is slidably connected inside the sliding frame 46, the slider 49 is fixedly connected to the bottom of the inclined plate 45, and a return spring 410 is fixed between the slider 49 and the inner wall of the sliding frame 46, and two spring telescopic rods 48 are fixed at the position of the bottom of the vertical plate 41 corresponding to the sliding frame 46, and the extended end of the spring telescopic rod 48 is fixedly connected to the sliding frame 46, a transmission rod 44 is fixed between the second gears 42 at the top of the two second racks 3, and the sprocket 43 is fixedly sleeved on the transmission rod 44. In the initial state, when the detection component 2 is not close to the second rack 3, the spring telescopic rod 48 pushes the sliding frame 46 and the inclined plate 45 outward without contacting the chain 47. When the second rack 3 is engaged, the inclined block 212 will first contact the inclined surface of the inclined plate 45, and at the same time, the inclined plate 45 will be pushed to move backward through the second electric push rod 213 and the extrusion plate 214, and the detection component 2 will continue to move backward to maintain the contact between the inclined block 212 and the inclined plate 45. The spring expansion plate will shrink after being squeezed, and the back of the inclined plate 45 will be squeezed and contacted with the chain 47. Then, as the detection component 2 continues to move, through the cooperation between the inclined block 212 and the inclined surface of the inclined plate 45, the inclined plate 45 will slide along the slide frame 46 through the bottom slider 49. Because the chain 47 itself has a certain hardness, it will move synchronously with the inclined plate 45 under the extrusion of the inclined plate 45, and the chain 47 will drive the sprocket 43 to rotate counterclockwise, and the second gear 42 connected to the sprocket 43 will also rotate synchronously with the second gear The bar 3 is engaged, driving the vertical plate 41, the first rack 11, the slide rail 1 and the detection component 2 to move a distance in the direction of the second rack 3. The buckle frame 411 slides along the bottom of the second rack 3 to maintain the stability of the device when moving. During the movement of the inclined plate 45, the second electric push rod 213 is shortened cooperatively, but the extrusion plate 214 is kept to limit the extrusion of the inclined plate 45, so that it cannot escape the extrusion effect on the chain 47. After the movement is completed, the detection component 2 returns to the original path, and the inclined plate 45 first pops outward through the spring telescopic plate, and then returns to its original position through the return spring 410 inside the slide frame 46. Because the two second gears 42 are connected by a transmission rod 44, when the detection component 2 moves to one side, it will drive the moving components 4 at both ends to move synchronously.Then, the moving path of the detection component 2 is set to be limited by the length of the slide rail 1, and the plants in the cultivation room are monitored back and forth.

[0035] When the device is used, the lengths of the first rack 11, the slide rail 1 and the second rack 3 are customized according to the length and width of the culture chamber. The second rack 3 is fixed to the two ends of the culture chamber through the fixing plates 31 at both ends. The first gear 29 is driven to rotate by the motor, and the first gear 29 is engaged with the first rack 11. The slide 21 slides along both sides of the slide rail 1, so that the detection component 2 moves stably along the path of the first rack 11 and the slide rail 1, and performs mobile monitoring of the culture area of ​​the lower layer. Through sensing devices such as pH sensors, the composition of the nutrient solution is monitored online, and the formula of the nutrient solution is adjusted in time to meet the needs of plants at different growth stages. Through temperature sensors 210 and humidity The sensor 211 and the camera 24 collect the temperature, humidity and plant images in the moving area, and accurately grasp the precise values ​​of each area. In the initial state, when the detection component 2 has not yet approached the second rack 3, the spring telescopic rod 48 pushes the slide frame 46 and the inclined plate 45 outward without contacting the chain 47. When the moving component 4 approaches the second rack 3 at one end, the inclined block 212 will first contact the inclined surface of the inclined plate 45, and at the same time, the inclined plate 45 will be pushed backward by the second electric push rod 213 and the extrusion plate 214. The detection component 2 continues to move backward, keeping the contact between the inclined block 212 and the inclined plate 45. The spring telescopic plate is squeezed and contracts, and the back of the inclined plate 45 The chain 47 is squeezed and contacted with the chain 47. Then, as the detection component 2 continues to move, the inclined block 212 cooperates with the inclined surface of the inclined plate 45, and the inclined plate 45 slides along the slide frame 46 through the slider 49 at the bottom. Because the chain 47 itself has a certain hardness, it will move synchronously with the inclined plate 45 under the squeezing action of the inclined plate 45. The chain 47 drives the sprocket 43 to rotate counterclockwise, and the second gear 42 connected to the sprocket 43 will also rotate synchronously and mesh with the second rack 3, driving the vertical plate 41, the first rack 11, the slide rail 1 and the detection component 2 to move a distance in the direction of the second rack 3. The buckle frame 411 slides along the bottom of the second rack 3 to maintain the stability of the device when moving. During the movement of the inclined plate 45, the second electric push rod 213 is shortened cooperatively, but the extrusion plate 214 keeps limiting the extrusion of the inclined plate 45, so that it cannot escape the extrusion of the chain 47. After the movement is completed, the detection component 2 returns to its original path, and the inclined plate 45 first pops out through the spring telescopic plate, and then returns to its original position through the reset spring 410 inside the slide frame 46. Because the two second gears 42 are connected by a transmission rod 44, when the detection component 2 moves to one side, it will drive the moving components 4 at both ends to move synchronously, and then set the moving path of the detection component 2 to be limited to the length of the slide rail 1, so as to monitor the plants in the culture room back and forth.
