[0047] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0048] Example 1

[0049] Please see Figure 1 - Figure 8 A pest and disease protection device for forsythia cultivation, comprising:

[0050] Base plate 1;

[0051] Two fixed frames 2 are arranged symmetrically at the top and bottom, with the lower fixed frame 2 fixedly installed on the base plate 1, and the monitoring component 8 fixedly installed on the upper fixed frame 2;

[0052] Insect-attracting lamp 3 is fixedly installed on the top wall inside the mounting frame 2;

[0053] The electrical grid 4 is fixedly installed on the outer wall of the mounting frame 2;

[0054] A water tank 5 is set between two fixed frames 2, and the water tank 5 is fixedly installed on the lower fixed frame 2, while the upper fixed frame 2 is fixedly installed on the top of the water tank 5.

[0055] The extraction component 6 and the monitoring mechanism are respectively installed inside the water tank 5;

[0056] A spray assembly 7 is installed at the output end of the extraction assembly 6;

[0057] The protective frame 9 is fitted onto the outside of the fixed frame 2;

[0058] Fixed frame 13 is fixedly installed inside the protective frame 9;

[0059] Four brushes 14 are arranged in a rectangular shape and fixedly installed on the four inner walls of the fixed frame 13;

[0060] Two U-shaped frames 10 are symmetrically arranged on the left and right, and the two ends of the U-shaped frames 10 are fixedly connected to the two protective frames 9 respectively. A square plate 11 is installed on one side of the U-shaped frame 10.

[0061] And an electric telescopic rod 12 fixedly installed at the bottom of the square plate 11, with the bottom of the electric telescopic rod 12 fixedly connected to the fixing frame 2 below.

[0062] This utility model provides a pest and disease protection device for Forsythia cultivation. Through an insect-attracting lamp 3 and an electric grid 4, it can comprehensively attract and kill both flying and ground-based pests. The extraction component 6 extracts pesticide solution from the water tank 5 and sprays it out through the spraying component 7, thus achieving pest control. This diversifies the device's pest control methods. While spraying, a monitoring agency can detect the liquid level in the water tank 5, reminding staff to replenish the pesticide solution to avoid affecting the pest and disease control effect. When the monitoring component 8 detects windy or rainy weather, the controller on the monitoring component 8 controls the electric telescopic rod 12 to retract and lower the square plate 11. The lowering square plate 11 then synchronously drives the U-shaped frame 10, allowing the U-shaped frame 10 to descend and protect the electric grid 4. Normally, when a preset time is reached, the controller also controls the electric telescopic rod 12 to extend and retract, causing the protective frame 9 to rise and fall, which in turn drives the brush 14 to clean the surface of the electric grid 4. This gives the device good protective capabilities, preventing damage in extreme weather conditions while maintaining its pest control effectiveness.

[0063] It should also be noted that the spraying time of the extraction component 6 and the spraying component 7 will not be continuous, but will be based on a preset time.

[0064] Furthermore, a fixing plate is fixedly installed on the inner wall of the water tank 5, and an inlet pipe 15 is fixedly installed through the water tank 5 and the fixing plate. The fixing plate divides the water tank 5 into two independent chambers, one is the water chamber and the other is the installation chamber.

[0065] Specifically, the inner side of the water tank 5 is divided into a water cavity and an installation cavity by a fixing plate, making the overall structure more compact and also protecting the extraction component 6 from the influence of severe weather.

[0066] Furthermore, the monitoring mechanism includes a T-shaped rod 16 that runs through the mounting plate, a float block 17 that is fixedly installed at the bottom of the T-shaped rod 16, and a pressure sensor 18 that is fixedly installed at the top of the mounting plate.

[0067] Specifically, when the liquid in the water tank 5 drops, the float 17 and the T-shaped rod 16 drop synchronously with the liquid. Then, when the pressure sensor 18 senses the pressure of the T-shaped rod 16, the pressure sensor 18 immediately inputs the pressure signal to the controller in the monitoring component 8. The controller then immediately sends information to the PC, thereby reminding the staff to replenish the pesticide solution and avoid affecting the pest and disease control effect.

[0068] Furthermore, the extraction assembly 6 includes a water pump 61 fixedly mounted on the mounting plate, an extraction pipe 62 fixedly connected to the input end of the water pump 61, and the bottom of the extraction pipe 62 extends into the water chamber. The output end of the water pump 61 is fixedly connected to a delivery pipe 63, and the spray assembly 7 is fixedly connected to the delivery pipe 63.

[0069] Specifically, the water pump 61 and the extraction pipe 62 extract the liquid from the bottom of the water tank 5, and then the extracted liquid is transported to the spray assembly 7 through the delivery pipe 63 and sprayed out from the spray assembly 7, thereby enabling insecticidal spraying.

[0070] Furthermore, the spray assembly 7 includes a first tee connector fixedly installed on the top of the delivery pipe 63, with a first connecting pipe 71 fixedly connected to both ends of the first tee connector, a second tee connector 72 fixedly installed at the other end of the first connecting pipe 71, a second connecting pipe 73 fixedly installed at both ends of the second tee connector 72, a third tee connector 74 fixedly installed at the other end of the second connecting pipe 73 extending to the outside of the water tank 5, and a third connecting pipe 75 fixedly installed at one end of the third tee connector 74.

[0071] The other end of the third connecting pipe 75 is fixedly installed with a right angle connector 76. A U-shaped pipe 77 is provided on the outside of the water tank 5, and the two ends of the U-shaped pipe 77 are fixedly connected to the right angle connector 76 and the third tee connector 74 respectively. Two rows of atomizing nozzles are fixedly installed on the outer wall of the U-shaped pipe 77.

[0072] Specifically, through the first tee connector, the first connecting pipe 71, the second tee connector 72, the second connecting pipe 73, the third tee connector 74, the third connecting pipe 75, and the right-angle connector 76, the delivery pipe 63 can deliver the pesticide solution to the U-shaped pipe 77. Then, through the atomizing nozzle on the U-shaped pipe 77, the pesticide solution can be sprayed onto the forsythia, thereby performing insecticidal treatment and diversifying the insecticidal methods of the device.

[0073] Furthermore, the monitoring component 8 includes a mounting bracket 81 fixedly installed on the top of the mounting frame 2. A control box 82 is fixedly installed on the inner top wall of the mounting bracket 81. A wind speed sensor 83 and a raindrop sensor 84 are fixedly installed on the top of the mounting bracket 81, and both the wind speed sensor 83 and the raindrop sensor 84 are electrically connected to the controller inside the control box 82.

[0074] Specifically, the wind speed sensor 83 and the raindrop sensor 84 can monitor the weather conditions. When the wind speed sensor 83 and the raindrop sensor 84 detect strong winds or rain, the controller in the control box 82 controls the electric telescopic rod 12 to retract and drive the square plate 11 to descend. Then, the descending square plate 11 synchronously drives the U-shaped frame 10, so that the U-shaped frame 10 can descend and protect the power grid 4.

[0075] Furthermore, a collection frame 19 is provided below the fixing frame 2. Two inverted T-grooves 20 are symmetrically opened on the collection frame 19. Four inverted L-plates 21 are arranged in a rectangular pattern above the collection frame 19, and the collection frame 19 is snapped onto the fixing frame 2 through the inverted L-plates 21.

[0076] Each of the four inverted L-plates 21 has an inverted T-plate fixedly installed at its bottom. The four inverted T-plates are paired up and interlocked with the two inverted T-grooves 20 respectively. The top of the inverted L-plates 21 is threaded with a hand screw 22, and the screw end of the hand screw 22 is in contact with the fixing bracket 2.

[0077] Specifically, the inverted L-plate 21 is manually inserted into the fixing frame 2, and then the inverted L-plate 21 is manually moved so that it can slide and engage with the fixing frame 2 under the action of the inverted T-plate and the inverted T-groove 20. Then, the hand screw 22 is manually turned and its screw end is tightly pressed against the fixing frame 2, so that the collection frame 19 can be installed below the fixing frame 2, and the collection frame 19 can collect the insect corpses cleaned by the brush 14.

Insertion plates 25 are fixedly installed on both sides of the inner side of the protective shell 24 and are inserted into the grooves on both sides of the square plate 11.

[0080] The technical solution provided in this embodiment is as follows: the plug-in plate 25 is manually plugged into the groove on the square plate 11, so that the protective shell 24 can be installed on the square plate 11, and then, with the cooperation of the protective plate 23, the electric telescopic rod 12 can be protected.

[0081] Furthermore, a protective mechanism is provided on the outer side of the electric telescopic rod 12, and the protective mechanism is inserted into the inner side of the protective plate 23 and the protective shell 24.

[0082] Specifically, the protective mechanisms in the protective plate 23 and the protective shell 24 can provide comprehensive protection for the electric telescopic rod 12, without affecting the descent of the electric telescopic rod 12, the square plate 11, the protective plate 23, and the protective shell 24.

[0083] Furthermore, the protective mechanism includes a first U-shaped shell 26 and a second U-shaped shell 27 arranged symmetrically.
