Description

Technical Field

[0001] The utility model belongs to the technical field of field pest monitoring, and particularly relates to a large-field pest and disease monitoring system. Background Art

[0002] Traditional large-field pest and disease monitoring devices usually insert a pole with soil detection sensors such as soil humidity and pH into the field soil. The multifunctional bitter gourd field pest and disease monitoring device disclosed in the Chinese utility model patent with the patent publication number CN209201963U includes a base and a column. A chassis is arranged on the column, a second support column is arranged on the chassis, an electric knob is arranged below the second support column, a protective glass shell is arranged below the electric knob, and an infrared camera is arranged inside the protective glass shell. Although pests can be monitored through the infrared camera, during monitoring, the monitoring height of the thermal imager is not easy to adjust, and different height positions of crops cannot be detected. The farmland environment detection device disclosed in the Chinese utility model patent with the patent publication number CN210833640U inserts a soil humidity detection device into the fixed rod and inserts the fixed rod with the soil humidity detection device into the soil to facilitate the detection of the soil humidity near the crops. However, this device can only detect the soil humidity and cannot detect the pH value, conductivity, and nitrogen, phosphorus, and potassium content in the soil. Moreover, in the above patent documents, when it is necessary to change the monitoring position, the device needs to be manually pulled out from the original place and then reinserted at the corresponding position, which is cumbersome and time-consuming and laborious to carry.

[0059] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0060] Embodiment 1

[0061] As Figures 1-11As shown in the figure, a field pest and disease monitoring system includes a mobile trolley 1 and a support rod 2 fixedly connected to the mobile trolley 1. A monitoring camera 21 is installed on the support rod 2 to monitor crops in real time. A thermal imager 22 is fixedly connected to the bottom of the monitoring camera 21. The thermal imager 22 can perform thermal imaging scans on the crops and soil within the range to facilitate the staff to monitor pests on the crops and soil. The monitoring principle of the monitoring camera 21 and the working principle of the thermal imager 22 to perform thermal imaging scans on the crops and soil within the range belong to the prior art and will not be elaborated here.

[0062] A bird repeller 10 is installed on the support rod 2;

[0063] A lifting structure, a lifting structure is installed on one side of the support rod 2. The lifting structure includes a lifting cable 3. The lifting cable 3 is slidably sleeved on the support rod 2. The monitoring camera 21 is fixedly connected to the lifting cable 3. The lifting structure drives the monitoring camera 21 and the thermal imager 22 to move up and down through the lifting cable 3, so as to detect crops at different heights in the field.

[0064] A sensor lifting structure is also installed on the mobile trolley 1. A soil detection sensor 7 is detachably installed on the sensor lifting structure. The soil detection sensor 7 is inserted into the soil through the sensor lifting structure to facilitate the detection of the temperature, humidity, nitrogen, phosphorus, potassium content, pH value, and conductivity of the soil beside the crops. When it is necessary to detect the soil in different ranges, the soil detection sensor 7 inserted into the soil can be taken out only through the sensor lifting structure, and the field pest and disease monitoring system can be moved to the area to be detected through the mobile trolley 1.

[0065] Further, as Figure 1 and Figure 3 shown in the figure, a chassis 4 is installed on the mobile trolley 1. A storage battery 41 and a central control processor 42 electrically connected to the storage battery 41 are installed in the chassis 4. The central control processor 42 is in signal transmission connection with an external control device. A solar panel 43 is fixedly connected to one side of the support rod 2. The solar panel 43 is electrically connected to the storage battery 41 and the central control processor 42 through a transducer respectively;

[0066] The mobile trolley 1, the bird repeller 10, the monitoring camera 21, the thermal imager 22, the lifting structure, the sensor lifting structure, and the soil detection sensor 7 are all electrically connected to the central control processor 42 to facilitate the staff to perform unified control through the central control processor 42.

[0067] The solar panel 43 converts solar energy into electrical energy through a transducer to supply power to the central control processor 42, and supplies power to the mobile cart 1, the monitoring camera 21, the thermal imager 22, the lifting type lifting structure, the sensor lifting structure and the soil detection sensor 7 through the central control processor 42. When the power is insufficient, the battery 41 can be used for auxiliary power supply, and the solar panel 43 can also charge the battery 41.

[0068] Further, as Figure 3 shown, a support rod slot 101 is provided on the mobile cart 1, and the bottom of the support rod 2 is fixedly inserted into the support rod slot 101;

[0069] As Figure 4 shown, inner grooves 201 are provided on both sides of the support rod 2; a wire management cavity 202 is also formed on the support rod 2, and the wire management cavity 202 is located between the two inner grooves 201;

[0070] The monitoring camera 21 is installed on one of the inner grooves 201, and the electrical wires of the monitoring camera 21 and the thermal imager 22 are placed in the wire management cavity 202 to prevent the electrical wires of the monitoring camera 21 and the thermal imager 22 from being exposed.

[0071] Further, as Figure 4 shown, limiting rails 2011 are provided on both sides of one of the inner grooves 201, and moving wheels 23 are rotatably connected to both sides of the monitoring camera 21. The moving wheels 23 on the same side are in rolling contact with the limiting rails 2011; the monitoring camera 21 rolls in the limiting rails 2011 through the moving wheels 23, thereby reducing the friction when the monitoring camera 21 moves up and down;

[0072] A first avoidance opening 203 is formed on the support rod 2, and the wire management cavity 202 is communicated with the inner groove 201 on the side close to the monitoring camera 21 through the first avoidance opening 203. When the monitoring camera 21 and the thermal imager 22 move up and down, the electrical wires on the monitoring camera 21 and the thermal imager 22 move up and down between the wire management cavity 202 and the inner groove 201 through the first avoidance opening 203, preventing the electrical wires of the monitoring camera 21 and the thermal imager 22 from being squeezed by the support rod 2 and damaged.

[0073] Further, as Figure 4 and Figure 5As shown in the figure, a plug-in member 24 is inserted into the top of the support rod 2. Symmetrically rotatably connected to the plug-in member 24 are upper cable sheaves 25. Rotatably connected to each of the two inner grooves 201 are lower cable sheaves 26. The support rod 2 is provided with a second avoidance opening 204, and the two lower cable sheaves 26 are respectively located on both sides of the second avoidance opening 204. By providing the upper cable sheaves 25 and the lower cable sheaves 26, the friction when the lifting cable 3 moves can be reduced. By providing the second avoidance opening 204, it can be ensured that the lifting cable 3 can smoothly move from one inner groove 201 to the other inner groove 201.

[0074] The lifting and lowering structure further includes a first drive motor 27 and a cable winding roller 28. The cable winding roller 28 is rotatably connected in one of the inner grooves 201. Symmetrically wound around the cable winding roller 28 are two sets of lifting cables 3. The same ends of the two sets of lifting cables 3 are in rolling contact with the two upper cable sheaves 25 and are fixedly connected to the top of the monitoring camera 21 at their ends. The other ends of the two sets of lifting cables 3 are in rolling contact with the two lower cable sheaves 26 and are fixedly connected to the bottom of the monitoring camera 21 at their ends. The first drive motor 27 is fixedly installed on one side of the support rod 2, and its output shaft passes through the support rod 2 and is fixedly connected to the cable winding roller 28.

[0075] The first drive motor 27 is electrically connected to the central control processor 42, so that the staff can control the first drive motor 27 through the central control processor 42.

[0076] Specifically, when it is necessary for the monitoring camera 21 and the thermal imager 22 to move downward, the output shaft of the first drive motor 27 drives the cable winding roller 28 to rotate clockwise. When the cable winding roller 28 rotates, it will wind up the lifting cable 3 below it and at the same time release an equal length of the lifting cable 3 upward, so that the lifting cable 3 as a whole moves in a closed loop in the clockwise direction, thereby pulling the monitoring camera 21 downward. When it is necessary for the monitoring camera 21 to move upward, it is only necessary to drive the cable winding roller 28 to rotate counterclockwise through the output shaft of the first drive motor 27.

[0077] Further, as Figure 4 shown, a wind vane 5 is fixedly connected to the top of the plug-in member 24, so as to facilitate the staff to monitor the wind direction change in the field.

[0078] As Figure 5 shown, isolation rubber sleeves 29 are sleeved on the upper cable sheaves 25, the lower cable sheaves 26 and the cable winding roller 28. The isolation rubber sleeves 29 are located between the two sets of lifting cables 3 to prevent the two sets of lifting cables 3 from interfering and winding with each other.

[0079] Embodiment 2

[0080] As Figures 1-11As shown in the figure, the following improvements have been made to this embodiment based on Embodiment 1: Further, as Figure 3 shown, a base slot 102 is provided on the mobile trolley 1. As Figure 6 shown, the sensor lifting structure includes a base 6, a transmission gear ring 61, a driven gear 62, and a cover plate 63. The cover plate 63 is detachably and fixedly installed on the top of the base 6;

[0081] As Figures 6-9 shown, the base 6 is fixedly inserted into the base slot 102. The base 6 is annular and hollow inside. As Figure 7 shown, an inner sliding groove 6301 is provided on the inner wall of the cover plate 63, and the transmission gear ring 61 is slidably connected to the inner sliding groove 6301. As Figure 9 shown, a plurality of gear support pipes 64 are fixedly connected to the bottom of the inner cavity of the base 6, and the top of each gear support pipe 64 is slidably connected to a driven gear 62;

[0082] As Figure 6 shown, a second driving motor 65 is fixedly installed on the cover plate 63. The second driving motor 65 is electrically connected to the central control processor 42, so that the staff can control the second driving motor 65 through the central control processor 42. The output shaft of the second driving motor 65 penetrates through the cover plate 63 and extends into the inner cavity of the base 6, and a driving gear 66 is fixedly sleeved on the end of the output shaft. The driving gear 66 and a plurality of driven gears 62 are both meshed with the transmission gear ring 61. The driving gear 66 is driven to rotate by the output shaft of the second driving motor 65, and the transmission gear ring 61 is driven to rotate under the meshing action;

[0083] Further, as Figures 6-9 shown, circular alignment sliding grooves 6201 are provided at the top and bottom of the driven gear 62. The driven gear 62 is slidably connected to the corresponding gear support pipe 64 through the alignment sliding groove 6201 at its bottom;

[0084] A limiting ring 6302 corresponding to the driven gear 62 is provided at the bottom of the cover plate 63. The limiting ring 6302 is slidably connected to the alignment sliding groove 6201 at the top of the corresponding driven gear 62; The bottom of the corresponding driven gear 62 can be supported and positioned by the gear support pipe 64. When the cover plate 63 is installed on the top of the base 6, the top of the driven gear 62 can be limited by the corresponding limiting ring 6302 to prevent the driven gear 62 from shaking during rotation.

[0085] As Figures 7-9As shown in the figure, an internal thread meshing port 6202 communicating with the inner cavity of the gear support pipe 64 is provided on the driven gear 62. A through port 6303 corresponding to the internal thread meshing port 6202 is provided on the cover plate 63. A screw rod 67 is threadedly engaged with the internal thread meshing port 6202. The top of the screw rod 67 extends out of the through port 6303, and limit bumps 6701 are symmetrically and fixedly connected to the side of the top end. The sensor lifting structure further includes a screw rod limit chuck 68 fixedly connected to the cover plate 63. A bump limit groove 6801 corresponding to the limit bumps 6701 is provided on the screw rod limit chuck 68. The limit bumps 6701 are slidably connected to the corresponding bump limit grooves 6801. By providing the bump limit grooves 6801, the limit bumps 6701 can be limited to prevent the driven gear 62 from driving the screw rod 67 to rotate together.

[0086] Further, as Figure 9 shown, a sensor socket 6702 is provided on the screw rod 67. The sensor socket 6702 communicates with the inner cavity of the gear support pipe 64;

[0087] As Figure 8 and Figure 9 shown, the soil detection sensor 7 includes a soil temperature and humidity sensor 71, a soil pH sensor 72, a soil nitrogen, phosphorus and potassium sensor 73, and a soil conductivity sensor 74 electrically connected to the central control processor 42. The soil temperature and humidity sensor 71, the soil pH sensor 72, the soil nitrogen, phosphorus and potassium sensor 73, and the soil conductivity sensor 74 correspond to multiple screw rods 67 one by one and are threadedly connected in the corresponding sensor sockets 6702;

[0088] The detection probes of the soil temperature and humidity sensor 71, the soil pH sensor 72, the soil nitrogen, phosphorus and potassium sensor 73, and the soil conductivity sensor 74 all penetrate out of the corresponding gear support pipes 64.

[0089] Specifically, when the transmission gear ring 61 rotates, multiple driven gears 62 will be driven to rotate simultaneously through the meshing action. When the driven gear 62 rotates, under the threaded engagement of the internal thread meshing port 6202 and the screw rod 67, the screw rod 67 will slide downward along the bump limit groove 6801, so as to insert the soil temperature and humidity sensor 71, the soil pH sensor 72, the soil nitrogen, phosphorus and potassium sensor 73, and the soil conductivity sensor 74 into the soil simultaneously, and detect the soil temperature and humidity, nitrogen, phosphorus and potassium component content, pH value, and conductivity beside the crops.

[0090] When it is necessary to detect soils in different ranges, only need to drive the driving gear 66 to rotate in reverse through the output shaft of the second driving motor 65. Driven by the cooperation of the transmission gear ring 61 and the driven gear 62, the screw rod 67 slides upward along the bump limiting groove 6801, so as to simultaneously pull out the soil temperature and humidity sensor 71, soil pH sensor 72, soil nitrogen, phosphorus and potassium sensor 73 and soil conductivity sensor 74 inserted into the soil;

[0091] Further, as Figure 9 shown, a plurality of scraping sleeves 8 are detachably and fixedly connected to the bottom of the base 6. The scraping sleeves 8 correspond to the soil temperature and humidity sensor 71, soil pH sensor 72, soil nitrogen, phosphorus and potassium sensor 73 and soil conductivity sensor 74 one by one, and are slidably sleeved on the detection probes of the corresponding soil temperature and humidity sensor 71, soil pH sensor 72, soil nitrogen, phosphorus and potassium sensor 73 and soil conductivity sensor 74;

[0092] When the soil temperature and humidity sensor 71, soil pH sensor 72, soil nitrogen, phosphorus and potassium sensor 73 and soil conductivity sensor 74 in the soil move upward and reset, the dirt and stones attached to the detection probes can be scraped off through the scraping sleeves 8, avoiding the dirt and stones from adhering to the detection probes for a long time and affecting subsequent detections;

[0093] A plurality of protection sleeves 9 corresponding to the screw limiting chucks 68 are detachably installed on the cover plate 63. The protection sleeves 9 are sleeved on the corresponding screw limiting chucks 68. The tops of the soil temperature and humidity sensor 71, soil pH sensor 72, soil nitrogen, phosphorus and potassium sensor 73 and soil conductivity sensor 74 all slide through the corresponding protection sleeves 9. By providing the protection sleeves 9, it is possible to prevent the stems and leaf fragments of the field from falling into the bump limiting groove 6801 and affecting the sliding of the limiting bump 6701 in the bump limiting groove 6801.

[0094] In summary, the working process of the present utility model is as follows: The mobile trolley 1 moves the field pest and disease monitoring system to the corresponding field. The output shaft of the second driving motor 65 drives the driving gear 66 to rotate. Under the meshing action, the transmission gear ring 61 is driven to rotate. When the transmission gear ring 61 rotates, a plurality of driven gears 62 are driven to rotate simultaneously through the meshing action. When the driven gear 62 rotates, under the thread meshing of the internal thread meshing port 6202 and the screw rod 67, the screw rod 67 slides downward along the bump limiting groove 6801, so as to simultaneously insert the soil temperature and humidity sensor 71, soil pH sensor 72, soil nitrogen, phosphorus and potassium sensor 73 and soil conductivity sensor 74 into the soil, and detect the soil temperature and humidity, nitrogen, phosphorus and potassium component content, pH value, and conductivity beside the crop;

[0095] When it is necessary to monitor the downward movement of the camera 21 and the thermal imager 22, the output shaft of the first drive motor 27 drives the rope winding roller 28 to rotate clockwise. When the rope winding roller 28 rotates, it will wind up and recycle the lifting cable 3 below it, and at the same time release an equal length of the lifting cable 3 upward, so that the overall lifting cable 3 moves in a closed loop in the clockwise direction, thereby pulling the monitoring camera 21 downward; when it is necessary to move the monitoring camera 21 upward, only need to drive the rope winding roller 28 to rotate counterclockwise through the output shaft of the first drive motor 27;

[0096] When it is necessary to detect soils in different ranges, only need to drive the driving gear 66 to rotate in the reverse direction through the output shaft of the second drive motor 65. Under the cooperation of the transmission gear ring 61 and the driven gear 62, drive the screw rod 67 to slide upward along the bump limiting groove 6801, so as to simultaneously pull out the soil temperature and humidity sensor 71, soil pH sensor 72, soil nitrogen, phosphorus and potassium sensor 73 and soil conductivity sensor 74 inserted into the soil, and move the field pest monitoring system to the corresponding field through the mobile trolley 1.
