[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-4 The device shown is an automatic foreign object removal device inside a rain gauge, including a rain gauge body 1, and a funnel installed inside the rain gauge body 1.

[0025] Furthermore, a connecting ring 4 is provided inside the rain gauge body 1 to support the shielding net 2 and facilitate its rotation. The inner cavity of the connecting ring 4 is fitted with the shielding net 2 for collecting foreign objects that fall inside the rain gauge body 1. The aperture size of the shielding net 2 is 1-2 cm, so it will not affect the collection of rainwater. The shielding net 2 helps to block impurities and foreign objects that fall inside the rain gauge body 1, preventing blockage of the funnel. The rain gauge body 1 is provided with an auxiliary mechanism 3 for tilting the shielding net 2 to collect foreign objects that fall. The auxiliary mechanism 3 includes a collection frame 31, a fixed shaft 33, and a servo motor. The collection frame 31 has an arc-shaped side to facilitate its fit against the outer wall of the rain gauge body 1. The collection frame 31 helps collect falling debris when the shielding net 2 is tilted, facilitating subsequent centralized processing. The fixed shaft 33 supports the connecting ring 4 and allows it to rotate around its center, facilitating the unloading of debris. The servo motor is electrically connected to an external power supply via an external switch. The servo motor drives the fixed shaft 33 to rotate, causing the connecting ring 4 to repeatedly rotate at a certain tilt angle a certain number of times, thus dislodging debris. The collection frame 31 is located on the side of the rain gauge body 1. The collection frame 31 has an arc-shaped plate 32 inside, which helps guide falling foreign objects and facilitates cooperation with the connecting ring 4, allowing the connecting ring 4 to impact the arc-shaped plate 32, causing the foreign objects in the shielding net 2 to vibrate and fall off. The servo motor is located outside the rain gauge body 1, and the fixed shaft 33 is rotatably mounted on the rain gauge body 1. The connecting ring 4 is connected to the rain gauge body 1 through the fixed shaft 33. The output end of the servo motor is connected to one of the fixed shafts 33. Assembly plates are fixedly connected to the top and bottom of the collection frame 31, and assembly bolts are threaded through the sides of the assembly plates. The assembly plates and assembly bolts facilitate... The collection frame 31 is installed and disassembled to remove foreign objects inside the collection frame 31. One end of the assembly bolt is threadedly connected to the rain gauge body 1. The side of the rain gauge body 1 is provided with an arc-shaped groove, and the arc plate 32 is embedded in the arc-shaped groove. The side of the collection frame 31 is provided with a through groove, and the side of the arc plate 32 is located inside the through groove. A pad 5 is fixedly connected to the inner wall of the rain gauge body 1, which is beneficial for supporting the connecting ring 4 when it is placed horizontally. The pad 5 is located at the bottom of the connecting ring 4. A motor box 34 is installed on the outside of the rain gauge body 1, which is beneficial for shielding and protecting the servo motor. The servo motor is installed inside the motor box 34.

[0026] Specifically, the collection frame 31 has an arc-shaped frame 35 inside. The arc-shaped frame 35 cooperates with the arc-shaped plate 32 to shield the interior of the collection frame 31, preventing rainwater from entering. The arc-shaped frame 35 is slidably inserted into the inner cavity of the through groove and the arc-shaped groove. A connecting rod 36 is fixedly connected to the inner wall of the arc-shaped frame 35, which facilitates the movement of the arc-shaped frame 35 and allows for driving operation. The outer wall of the connecting rod 36 is slidably inserted into the side of the collection frame 31. A sliding plate 37 is fixedly connected to the end of the connecting rod 36, which facilitates the movement of the connecting rod 36. A hydraulic cylinder is installed on the back of the collection frame 31. The hydraulic cylinder is electrically connected to an external power source through an external switch. The hydraulic cylinder drives the sliding plate 37 to move, facilitating the movement of the arc-shaped plate. The frame 35 moves, and the output end of the hydraulic cylinder is connected to the sliding plate 37. When it is necessary to remove foreign objects from the inside of the rain gauge body 1, the hydraulic cylinder drives the sliding plate 37 to move, which in turn drives the connecting rod 36 to move, pulling the arc frame 35 to move, exposing the inside of the through groove and the arc groove. Then, the servo motor drives the fixed shaft 33 to rotate, which in turn drives the connecting ring 4 to rotate, causing the shielding net 2 to rotate and tilt, and to rotate repeatedly at a certain speed and angle, so that the connecting ring 4 hits the arc plate 32 multiple times, which helps to vibrate the foreign objects on the shielding net 2, causing the foreign objects to fall onto the arc plate 32 and then fall into the inside of the collection frame 31. After the removal is completed, the shielding net 2 and the arc frame 35 return to their original positions.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
