The mobile seat is arranged at the bottom, the meteorological monitoring body is arranged on the mobile seat, and the bird-repelling platform and the solar power generation panel are arranged on opposite sides of the upper part of the meteorological monitoring body.
[0039] The solar panels can charge the equipment through solar power generation, the meteorological monitoring body can detect the meteorological information in the field, and the bird-scaring station can drive away the birds that land on the equipment through sound and rotation, thereby preventing the birds from landing on the equipment and affecting the equipment, thereby improving the accuracy of the equipment's meteorological perception.
[0040] However, the base of the device is supported by support rods, bases and universal wheels. When transporting the device to areas with soft soil in the field, the universal wheels are easily sunk into the soil and cannot be used, making it difficult to move and increasing the workload of operators.
[0041] To do this, please refer to Figure 1 The present application provides a new agricultural meteorological observation device, including a meteorological monitoring body 1, a bird-repelling platform 2, a solar power generation panel 3, a bottom plate 4 and a main column 5. Among them, the meteorological monitoring body 1, the bird-repelling platform 2 and the solar power generation panel 3 can all be the above-mentioned meteorological monitoring body 1, the bird-repelling platform 2, and the solar power generation panel 3, and only need to achieve the above-mentioned meteorological monitoring effect.

[0045] Please refer to Figure 1The bottom plate 4 and the main column 5 in the present application can cooperate to support and fix the meteorological monitoring body 1. At the same time, the cooperation between the first mounting portion 11 and the first mounting groove 41, and the second mounting portion 51 and the second mounting groove 42 can make the connection stability between the meteorological monitoring body 1, the bottom plate 4, and the main column 5 better. The bottom plate 4 is provided with a main storage hole 43, which can store the main column 5. During transportation, the above parts can be disassembled, and the main column 5 can be placed in the bottom plate 4. In areas where it is not convenient to use tools for transportation, it can be carried manually. The bottom plate 4 and the meteorological monitoring body 1 have a simple structure and a smaller volume, which is convenient for transportation. At the same time, the structure is easy to install.
[0046] In some examples, the first mounting portion 11 and the second mounting portion 51 may be the same, and the first mounting slot 41 and the second mounting slot 42 may be the same; or they may be different. The first mounting portion 11 and the second mounting slot 42, and the second mounting portion 51 and the second mounting slot 42 may be matched and connected, and the matching method may be any one of a variety of methods.
[0047] Please refer to Figure 2 Exemplarily, the first mounting portion 11 and the first mounting groove 41 can be bolts, threaded holes, or blocks, slots, or limiting holes and limiting protrusions. It should be noted that when the first mounting portion 11 and the first mounting groove 41 are limiting holes and limiting protrusions, the opening cross-section of the limiting hole needs to be smaller than the cross-section of the internal space of the limiting hole, and the limiting protrusion needs to have a certain elasticity so that the first mounting portion 11 and the first mounting groove 41 can have good connection stability after installation.

The structure of the bottom plate 4 can make it more stable when moving; when it is inconvenient to use tools for transportation, it can also be directly transported by staff. The regular structure is more convenient for taking and placing. At the same time, the components can be divided into two major parts. Whether it is transported by one person or two people, it can reduce the difficulty of transportation and make transportation faster and more convenient.

Similarly, the base plate 4 and the main column 5 may be fixedly connected through the through hole and the threaded hole.
[0060] Please refer to Figure 2 In some examples, the second mounting portion 51 is a threaded column, the second mounting slot 42 is a threaded hole, and the threaded column is threadedly matched with the threaded hole.
[0061] The threaded column and the threaded hole have a simple structure, are easy to manufacture, and have a low cost. At the same time, they can ensure good connection stability between the bottom plate 4 and the main body column 5 after connection.
[0062] In some examples, when the second mounting portion 51 is a threaded column and the second mounting slot 42 is a threaded hole, the threaded hole can be set at the center of the main column 5 to facilitate assembly of the two.
[0063] Please refer to Figure 2 In some examples, the first mounting portion 11 is a card block, the first mounting slot 41 is a card slot, and the card block is engaged with the card slot.
