[0021] 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.
[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:
[0023] A meteorological observation rain gauge snow melting device: It includes a measurement base 1. A water collecting pipe 11 is fixedly connected to the surface of the measurement base 1. A measuring cylinder 12 is arranged on the surface of the measurement base 1. The measuring cylinder 12 can measure the rainfall. A drain pipe 13 is arranged on the surface of the measuring cylinder 12. The water source inside the measuring cylinder 12 is discharged through the drain pipe 13 after the measurement is completed. A constant temperature heater 14 is fixedly connected to the inner surface of the water collecting pipe 11. A power cord 15 is arranged on the surface of the constant temperature heater 14. The power cord 15 outputs electricity to the constant temperature heater 14. The constant temperature heater 14 continuously generates heat with the support of electricity, thereby melting the snow water. A funnel-shaped through hole is opened at the top of the constant temperature heater 14, so that the snow water becomes liquid and flows to the measuring cylinder 12 after passing through the constant temperature heater 14. A leak hopper 16 is arranged on the inner surface of the measurement base 1. The leak hopper 16 is located at the bottom of the constant temperature heater 14 and can guide the liquid water to the measuring cylinder 12, thus facilitating the measurement. A maintenance mechanism is arranged on the surface of the water collecting pipe 11. The maintenance mechanism includes a fixing plate 2. The fixing plate 2 is fixedly connected to the surface of the water collecting pipe 11. A movable plate 21 is slidably connected to the surface of the fixing plate 2. A support ring 22 is fixedly connected to the surface of the movable plate 21. A connecting ring 23 is in contact connection with the surface of the support ring 22. A filter screen 24 is fixedly connected to the surface of the connecting ring 23. A fixing nut 25 is fixedly connected to the surface of the fixing plate 2. A bolt 26 is threadedly connected to the surface of the fixing nut 25. A limiting rod 27 is fixedly connected to the surface of the bolt 26. The filter screen 24 is located between the constant temperature heater 14 and the leak hopper 16 and can filter the liquid water, filter out impurities, and prevent impurities from entering the inside of the measuring cylinder 12. This maintenance mechanism can take out the filter screen 24 from the inside of the water collecting pipe 11 for cleaning and maintenance, avoiding the trouble of maintaining the filter screen 24 inside the water collecting pipe 11, and making the maintenance work of the filter screen 24 time-saving and labor-saving.
[0024] A shielding mechanism is arranged on the surface of the movable plate 21. The shielding mechanism includes a connecting frame 3. The connecting frame 3 is fixedly connected to the surface of the movable plate 21. A shielding plate 31 is fixedly connected to the surface of the connecting frame 3. A support rod 32 is fixedly connected to the surface of the fixing plate 2. A guiding block 33 is fixedly connected to the surface of the support rod 32. A sliding rail 34 is slidably connected to the surface of the guiding block 33. The sliding rail 34 is fixedly connected to the bottom of the shielding plate 31. The shielding mechanism can make the shielding plate 31 slide to the top of the water collecting pipe 11 and shield it during the process of the movable plate 21 being pulled out from the fixing plate 2, so as to avoid impurities in the measuring cylinder 12 when the shielding plate 31 is not filtered by the filter screen 24 at this time and ensure the cleanliness inside the measuring cylinder 12.
[0025] The fixing plate 2 is in a rectangular shape. A guiding groove is formed on the surface of the fixing plate 2. The guiding groove of the fixing plate 2 communicates with the interior of the water collecting pipe 11. The movable plate 21 slides on the guiding groove of the fixing plate 2. The movable plate 21 slides into the interior of the water collecting pipe 11 through the guiding groove of the fixing plate 2, so that the filter screen 24 on the movable plate 21 can filter the snow water inside the water collecting pipe 11. A circular hole is formed on the surface of the movable plate 21. The diameter of the circular hole of the movable plate 21 is the same as the inner diameter of the water collecting pipe 11. The outer ring of the support ring 22 is fixedly connected to the bottom of the circular hole of the movable plate 21. The outer diameter of the outer ring of the support ring 22 is the same as the diameter of the circular hole of the movable plate 21. The inner and outer rings of the support ring 22 and the connecting ring 23 are supported in the same way. The support ring 22 supports the filter screen 24 through the connecting ring 23. The connecting ring 23 and the filter screen 24 are limited on the circular hole of the movable plate 21, so as to conveniently move the connecting ring 23 and the filter screen 24 to a specified position inside the water collecting pipe 11 through the movable plate 21. The limiting rod 27 is in a "cross" shape. The limiting rod 27 rotates on the fixing nut 25 through the bolt 26. The limiting rod 27 restricts the sliding of the movable plate 21 on the guiding groove of the fixing plate 2 on the fixing nut 25. When one side of the limiting rod 27 contacts and connects to the surface of the movable plate 21 through rotation, the movable plate 21 cannot slide on the guiding groove of the fixing plate 2 at this time, and the fixing plate 2 restricts the movable plate 21 and the filter screen 24 inside the water collecting pipe 11.
[0026] The connecting frame 3 is in a triangular shape and can effectively support the shielding plate 31. The shielding plate 31 is in an "L" shape. The horizontal height of the bottom of the shielding plate 31 is the same as the horizontal height of the top of the water collecting pipe 11. During the sliding process of the shielding plate 31, it can move to the top of the water collecting pipe 11. When the shielding plate 31 contacts the support rod 32 during the sliding process, the shielding plate 31 cannot continue to slide towards the water collecting pipe 11. The sliding rail 34 slides on the top of the support rod 32 through the guiding block 33. The shielding plate 31 slides on the top of the support rod 32 through the sliding rail 34. The connecting frame 3 and the shielding plate 31 slide along with the movable plate 21. The cross-section of the shielding plate 31 is larger than the cross-section of the water collecting pipe 11. The shielding plate 31 can completely cover the top of the water collecting pipe 11 to prevent impurities from entering the metering cylinder 12 through the water collecting pipe 11.
[0027] Working principle: When the filter screen 24 needs to be maintained, rotate the bolt 26 on the fixing nut 25 to cancel the restriction of the limiting rod 27 on the movable plate 21. At this time, slide the movable plate 21 out of the guiding groove of the fixing plate 2, and the connecting ring 23 and the filter screen 24 on the movable plate 21 can be taken out from the interior of the water collecting pipe 11. The support ring 22 supports the connecting ring 23 and the filter screen 24 on the circular hole of the movable plate 21, and the connecting ring 23 and the filter screen 24 can be taken out from the circular hole of the movable plate 21 for cleaning and maintenance, avoiding the trouble of maintaining the filter screen 24 inside the water collecting pipe 11 and making the maintenance work of the filter screen 24 time-saving and labor-saving.
[0028] When the sliding-out movable plate 21 is used to clean and maintain the filter screen 24, the movable plate 21 drives the connecting frame 3 and the baffle plate 31 to slide synchronously. The baffle plate 31 slides on the support rod 32 through the guide block 33 and the slide rail 34, and the baffle plate 31 slides towards the water collecting pipe 11. When one side of the baffle plate 31 contacts the support rod 32, the baffle plate 31 completely covers the top of the water collecting pipe 11 at this time, so that after the filter screen 24 is taken out, dust can be prevented from entering the metering cylinder 12 from the water collecting pipe 11, ensuring the cleanliness inside the metering cylinder 12.
