[0002] In order to prevent the rain gauge sensor of the rain gauge from being affected by low temperature, according to relevant regulations of the meteorological department, it is necessary to cover the rain gauge before winter, and then uncover it after the weather warms up in the coming year. However, due to the scattered distribution of rain gauge stations, manual covering and uncovering will waste a lot of manpower and material resources, and the efficiency is extremely low.

[0003] Chinese Patent Publication No.: CN210465730U, discloses a device for covering and uncovering a rain gauge, including a fixed bracket for placing the rain gauge. A central control box is also provided on the fixed bracket. A guide rod is vertically upward provided at the bottom inside the central control box. A lifting rod is sleeved outside the guide rod. The upper end of the lifting rod penetrates through the top of the central control box. A cross arm is horizontally provided at the upper end of the lifting rod. One end of the cross arm away from the lifting rod is fixedly connected to the cover of the rain gauge. An elevating mechanism for driving the lifting rod to lift and a rotating mechanism for driving the lifting rod to rotate are provided inside the central control box. A covering control mechanism and an uncovering control mechanism are provided inside the central control box. A storage battery is provided inside the central control box. However, the above device has the following defects in use:

[0004] 1. After the cover of the rain gauge is uncovered, there is no special storage area, which is easy to adsorb dust and impurities, etc., and falls into the rain gauge after covering, resulting in blockage and affecting the remote measurement of rainfall.

[0005] 2. After the cover of the rain gauge is rotated and uncovered, it hangs in the air for a long time. The lifting rod and its cross arm are prone to tilt under the influence of wind, etc., and the sealing is not tight during covering, or even damages the edge of the rain gauge. Content of the Utility Model

[0006] The technical problem to be solved by the utility model is that there is no storage area for the cover of the rain gauge after uncovering, which is easy to adsorb dust and enter the rain gauge; at the same time, affected by external factors, the cover is prone to tilt, and it is easy to damage the inlet of the rain gauge during covering. In view of the above problems, an automatic rain gauge with a cover for covering and uncovering is proposed, including a base and a rain gauge. The rain gauge is arranged at one end of the base. A storage cavity is arranged at the other end of the base. A telescopic rod is arranged in the middle of the base and is located between the rain gauge and the storage cavity. The top of the telescopic rod is connected to a cover body through a cross bar. A driving part for driving the telescopic rod to rotate is arranged at the lower part of the storage cavity. A brush is arranged inside the opening of the storage cavity. An upper guard plate and a lower guard plate are arranged outside the storage cavity. The upper guard plate and the lower guard plate move relative to or towards each other simultaneously.

[0007] The technical solution of the present utility model, by setting the structure of the storage cavity, the cover body is stored in the storage cavity after the cover is opened, without being exposed outside, and it is not easy to adsorb dust and impurities, which may cause problems such as inaccurate rainfall measurement or rain gauge blockage when the cover is closed; at the same time, an upper guard plate and a lower guard plate are arranged outside the storage cavity. After the cover body is put into the storage cavity, the upper and lower guard plates close the opening of the storage cavity to prevent dust, impurities and moisture from entering; the storage cavity and the upper and lower guard plates can also play a supporting role to prevent the cover body from tilting due to external force shaking, unable to close the rain gauge or even causing damage to the cutting edge of the rain gauge; a brush is arranged at the opening of the storage cavity, which can clean the cover body, remove dust and impurities on the surface, and keep it clean and tidy.

[0008] As a preference for the technical solution of the present utility model, the storage cavity has a height. The lower part of the storage cavity is an installation cavity for the driving part. Two adjacent sides of the storage cavity are open, and one of the openings faces the rain gauge. The storage cavity is convenient for storing the cover body after the cover is opened, avoiding adsorption of dust and impurities.

Both the upper guard plate and the lower guard plate pass through the guide rod. Both the upper guard plate and the lower guard plate are threadedly connected to the lead screw. The threads at both ends of the lead screw are opposite. The lead screw is connected to the second motor. The second motor is arranged in the installation cavity. After the cover body enters the storage cavity, the upper guard plate and the lower guard plate move closer to each other by the rotation of the lead screw, blocking the opening of the storage cavity from the outside.

[0012] As a preference for the technical solution of the present utility model, the lead screw is parallel to the guide rod, and the guide rod prevents the upper guard plate and the lower guard plate from rotating or shaking along with the lead screw when moving up and down.

[0013] As a preference for the technical solution of the present utility model, semi-circular notches are arranged on the sides of the upper guard plate and the lower guard plate facing the rain gauge. The semi-circular notches of the upper guard plate and the lower guard plate enclose a through hole for passing the cross bar.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be described in detail with reference to the accompanying drawings in the embodiments of the present utility model. Figures 1-4 of the present utility model. Embodiment 1

[0023] As Figures 1-4 shown, the present utility model is an automatic rain gauge with a cover that can be opened and closed, including a base 1 and a rain gauge 2. The rain gauge 2 is fixedly installed at one end of the base 1, and an installation cavity is fixedly arranged at the other end of the base 1. A storage cavity 11 is fixedly arranged above the installation cavity.

[0024] The fixed end of the telescopic rod 3 is fixedly installed in the middle of the base 1 and is located inside the installation cavity. The movable end of the telescopic rod 3 extends out of the installation cavity. A horizontal crossbar is fixedly connected to the top of the telescopic rod 3, and the crossbar is fixedly connected to the side wall of the cover body 31. The telescopic rod 3 is entirely located between the rain gauge 2 and the storage cavity 11.

[0025] The storage cavity 11 is used to store the removed cover body 31 after the cover is lifted. Two adjacent sides of the storage cavity 11 are open, facilitating the entry of the cover body 31. One of the two open sides faces the rain gauge 2.

[0026] Brush 14 is provided at the inner edge of the opening of the storage cavity 11. The brush 14 is divided into two groups and is fixedly connected to the upper and lower walls of the storage cavity 11 respectively. In this way, when the cover body enters, the upper and lower parts of the brush 14 sweep across the upper and lower walls of the cover body 31 respectively, removing the dust and impurities adsorbed on the surface of the cover body 31.

[0027] A baffle 15 is also provided at the opening that does not face the rain gauge 2. The baffle 15 is rotatably connected to the upper wall of the storage cavity 11, perpendicular to the lower wall, and is located inside the brush 14. When the cover body 31 enters the storage cavity 11, the baffle 15 is pushed inward until the cover body 31 completely enters the storage cavity 11, and then the baffle 15 returns to the vertical position to block the opening on this side of the storage cavity 11. The baffle 15 is a selectively installed structure, and whether to install it can be selected according to needs. Its main purpose is to reduce the entry of a small amount of dust and impurities into the storage cavity 11 when the brush is working.

[0028] An upper guard plate 12 and a lower guard plate 13 are provided outside the storage cavity 11. The upper guard plate 12 and the lower guard plate 13 are attached to the outer wall of the storage cavity. Driven by the second motor 16, the upper guard plate 12 and the lower guard plate 13 move relative to or towards each other simultaneously.

[0029] A limiting block extends outward from the top of the storage cavity 11. The guide rod 18 is perpendicular to the horizontal plane, and its two ends are fixedly connected to the lower wall of the limiting block and the upper wall of the installation cavity respectively. The lead screw 17 is parallel to the guide rod 18. The lead screw 17 is rotatably arranged between the limiting block and the installation cavity. The upper guard plate 12 and the lower guard plate 13 are mirror - image settings, slidably connected to the guide rod 18, and are threadedly connected to the lead screw 17. The motor shaft of the second motor 16 is connected to the lead screw 17, and the second motor 16 is fixedly installed in the installation cavity.

[0030] The threads at both ends of the screw rod 17 are opposite, and the center plane of the screw rod 17 when started coincides with the center plane of the opening of the storage chamber 11. Therefore, when the second motor 16 is started, the screw rod 17 rotates, and the upper guard plate 12 and the lower guard plate 13 move relative to or toward each other at the same time, and move toward each other until the upper guard plate 12 is fitted with the limit block and stops. At this time, the opening of the storage chamber 11 is completely exposed, which is convenient for the cover body 31 to enter, and move relatively. When the upper guard plate 12 and the lower guard plate 13 move and fit together, they stop. At this time, the upper guard plate 12 and the lower guard plate 13 can just completely cover the opening of the storage chamber 11 on the outside, preventing dust and impurities from entering the storage chamber 11.

[0031] The upper guard plate 12 and the lower guard plate 13 are both recessed from the edge on one side facing the rain gauge 2 to form a semicircular notch. When the cover body 31 is stored, the upper guard plate 12 and the lower guard plate 13 move relative to each other at the same time, and the semicircular notches of the upper guard plate 12 and the lower guard plate 13 gradually fit together to form a through hole, which is used to pass the cross bar connected to the cover body 31.

[0032] The telescopic rod 3 itself can move in the vertical direction, so the cover body 31 can also move in the vertical direction, and the driving part driving the telescopic rod 3 to rotate in the horizontal direction is arranged in the installation cavity.

[0033] The driving part includes a driven wheel 32, the end face of the driven wheel 32 faces upward and is rotatably connected to the bottom of the installation cavity, the driving wheel 33 is meshed with the driven wheel 32, and the motor shaft of the first motor 34 is connected to the driving wheel 33. After the first motor 34 is started, the driving wheel 33 rotates to drive the driven wheel 32 to rotate, and the fixed end of the telescopic rod 3 is fixedly connected to the upper end face of the driven wheel, so the telescopic rod 3 rotates with the driven wheel 32, and the telescopic rod 3 can move in any direction.

[0034] The device is powered by batteries, which are charged by solar panels. Since it only needs to work once a year, it basically does not need to rely on other structures for energy supply. The batteries can be fixedly installed in the installation cavity to avoid accelerated weathering and wear due to wind and sun, and the entire device can be controlled by remote control, saving a lot of manpower and material resources.

[0035] The method of using the automatic cover-uncover rain gauge of the present embodiment is as follows:

[0036] Covering operation: First, the second motor 16 is started, the lead screw 17 rotates, the upper guard plate 12 and the lower guard plate 13 move towards each other, exposing the opening of the storage cavity 11. Then, the first motor 34 is started and rotates 90°. The driving wheel 33 drives the driven wheel 32 to also rotate 90°. The cover body 31 connected to the telescopic rod 3 rotates 90° and moves out of the storage cavity 11. Next, the second motor 16 is started and rotates in the reverse direction. The upper guard plate 12 and the lower guard plate 13 move relatively and fit together. Then, the telescopic rod 3 is started to lift the height of the cover body 31 above the rain gauge 2. The first motor 34 rotates 90° again, so that the whole cover body 31 is located directly above the rain gauge 2. Finally, the telescopic rod 3 is started, and the height of the cover body 31 drops to cover the rain gauge 2.

[0037] Uncovering operation: First, the telescopic rod 3 is started to lift the height of the cover body 31, and the cover body 31 is separated from the rain gauge 2. Then, the first motor 34 is started and rotates 90° in the reverse direction. The driving wheel 33 drives the driven wheel 32 to also rotate 90° in the reverse direction, and the cover body 31 also rotates 90° in the reverse direction. Then, the telescopic rod 3 is started, and the height of the cover body 31 drops until it is flush with the storage cavity 11. At the same time, the second motor is started, the lead screw 17 rotates, the upper guard plate 12 and the lower guard plate 13 move towards each other, exposing the opening of the storage cavity 11. Subsequently, the first motor 34 is started and rotates 90° in the reverse direction again. The cover body 31 enters the storage cavity 11 after passing through the brush 174. The brush 14 will remove the dust and impurities adsorbed on the surface of the cover body 11 to keep it clean. Finally, the second motor 16 is started and rotates in the reverse direction. The upper guard plate 12 and the lower guard plate 13 move relatively and fit together. At this time, the notch of the upper guard plate 12 and the lower guard plate 13 just engages with the cross bar to fixedly store the cover body 31 in the installation cavity 11.

[0038] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention.
