Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of meteorological monitoring equipment, specifically relating to a tipping bucket rain gauge. Background Technology
[0002] The tipping bucket rain gauge is an important rain gauge instrument that can digitize rainfall data in real time. It has advantages such as accurate timing, automatic data recording, and convenient data acquisition, compilation, and processing.
[0003] The working principle of a tipping bucket rain gauge is as follows: Rainwater enters the rain collector through the uppermost inlet, falls into the funnel, and flows into the tipping bucket measuring device. When the water level in the bucket reaches a certain height (e.g., 0.01 mm), the bucket loses its balance and tipes over. Each time the bucket tipps, a switch is activated, sending a pulse signal to the recorder. The recorder then controls the automatic recording pen to record the rainfall. This process is repeated to measure the rainfall.
[0004] Tipping bucket rain gauges typically have a rain inlet and a rain catcher. Since dust and impurities can affect the accuracy of rain gauges, existing technologies typically install filters on the rain catcher. However, these filters are usually horizontally placed, have limited filtration capacity, and are very prone to clogging, preventing rainwater from entering and affecting the measurement results.

[0046] Please refer to the following: Figures 1 to 4 The tipping bucket rain gauge provided by this utility model will now be described. The tipping bucket rain gauge includes a rain collector 10, an mounting cylinder 20, a water receiving funnel 30, a tipping bucket metering component 40, a filter screen 50, and a cleaning component. The rain collector 10 has an inverted conical structure; the mounting cylinder 20 is sleeved on the outside of the rain collector 10 and connected to it; the water receiving funnel 30 is located on the lower side of the rain collector 10 and connected to the mounting cylinder 20; the tipping bucket metering component 40 is located on the lower side of the water receiving funnel 30 and connected to the mounting cylinder 20; the filter screen 50 has a conical structure, is located on the upper side of the rain collector 10, and connected to it; the cleaning component is connected to the filter screen 50 and is used to clean the filter screen 50.
[0047] The cleaning assembly includes a scraper 61, a connecting plate 62, and a drive mechanism. The scraper 61 is located between the filter screen 50 and the rain collector 10 and is attached to the filter screen 50. The connecting plate 62 is located on top of the filter screen 50 and rotates with the filter screen 50. The connecting plate 62 is connected to the scraper 61. The power output end of the drive mechanism is connected to the connecting plate 62 to drive the connecting plate 62 to rotate.
[0048] Specifically, the filter screen 50 has a frustum-shaped structure, which facilitates the connection between the connecting plate 62 and the filter screen 50. The mounting cylinder 20, the water receiving funnel 30, and the tipping bucket metering component 40 all use existing components.
[0049] It should be noted that the function of the scraper 61 is to remove the debris from the surface of the filter screen 50. Therefore, the scraper 61 can be attached to the filter screen 50, attached to the inner wall of the rain collector 10, or spaced apart.
[0050] The beneficial effects of the tipping bucket rain gauge provided by this utility model are as follows: Compared with the prior art, the tipping bucket rain gauge provided by this utility model has a filter screen 50 in the rain collector 10, and the filter screen 50 has a conical structure, which has a larger filtration area and effectively reduces the possibility of clogging. Furthermore, the scraper 61 driven by the drive mechanism scrapes the surface of the filter screen 50, further preventing clogging.
[0051] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tipping bucket rain gauge provided in this utility model, the scraper 61 extends downward to the connection between the filter screen 50 and the rain collector 10 to scrape the entire filter screen 50 and prevent garbage from accumulating and clogging the bottom of the filter screen 50.
[0052] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tipping bucket rain gauge provided in this utility model, the scraper 61 is tilted from the filter screen 50 side to the rain collector 10 side towards the side opposite to the rotation direction of the scraper 61, so that during the rotation of the scraper 61, the garbage moves away from the filter screen 50 and moves along the scraper 61 towards the inner wall of the rain collector 10.
[0053] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tipping bucket rain gauge provided in this utility model, the scraper 61 tilts from bottom to top to the side opposite to the direction of rotation of the scraper 61. During the rotation of the scraper 61, the garbage gradually moves upward, and may even be thrown out of the rain collector 10 by rapid rotation, thereby reducing the degree of accumulation at the bottom of the filter screen 50.
[0054] like Figure 1 and Figure 2 As shown, in a specific embodiment of the tipping bucket rain gauge provided in this utility model, the scraper 61 is provided with a wear-resistant rubber strip 611 on the side facing the filter screen 50, and the wear-resistant rubber strip 611 is attached to the filter screen 50.
[0055] It should be noted that the wear-resistant rubber strip 611 is set between the scraper 61 and the filter screen 50. On the one hand, it can effectively increase the adhesion between the scraper 61 and the filter screen 50 and ensure cleaning efficiency. On the other hand, the hardness of the wear-resistant rubber strip 611 is less than that of the filter screen 50, which can effectively reduce the wear on the filter screen 50.
[0056] like Figure 3 and Figure 4As shown, in a specific embodiment of the tipping bucket rain gauge provided in this utility model, the cleaning component further includes a blowing mechanism. The blowing mechanism is located on the lower side of the filter screen 50 and on the front side of the scraper 61 in the rotation direction. It is used to blow the filter screen 50. The blowing mechanism is connected to the power output end of the drive mechanism and rotates synchronously with the scraper 61.
[0057] Specifically, such as Figure 3 and Figure 4 As shown, in a specific embodiment of the tipping bucket rain gauge provided in this utility model, the purging mechanism includes a purging pipe 71 and an air pump 73. The purging pipe 71 has multiple purging holes on the side facing the filter screen 50. The purging pipe 71 is connected to the power output end of the drive mechanism. The air pump 73 is connected to the filter screen 50 or the rain collector 10. The purging pipe 71 is connected to the air pump 73 through a flexible pipe so that air is continuously supplied to the purging pipe 71 through the flexible pipe during the rotation of the purging pipe 71.
[0058] It should be noted that some debris adheres tightly to the surface of the filter screen 50, while some debris becomes embedded in the holes of the filter screen 50. This debris is difficult to scrape off. Therefore, a blowing mechanism is installed on the underside of the filter screen 50. During operation, the blowing pipe 71 first blows the surface of the filter screen 50 from the inside out, and then the scraper 61 scrapes the blown area, improving cleaning efficiency.
[0059] Specifically, such as Figure 3 and Figure 4 As shown, in a specific embodiment of the tipping bucket rain gauge provided in this utility model, the driving mechanism includes a bracket 63, a motor assembly 64, and a transmission shaft 65. The bracket 63 is located on the lower side of the filter screen 50 and is connected to the rain collector 10; the motor assembly 64 is connected to the bracket 63; one end of the transmission shaft 65 is connected to the power output end of the motor assembly 64, and the other end passes through the filter screen 50 and is connected to the connecting plate 62.
[0060] The purging mechanism also includes a connecting frame 72, which is connected to the purging pipe 71 and the drive shaft 65; and an air pump 73 is connected to the bracket 63.
[0061] Specifically, the motor assembly 64 is assembled from an existing motor and reducer; the bracket 63 has a U-shaped structure and is located at the lower part of the rain collector 10, which serves as the mounting point for the motor assembly 64 and the air pump 73.
[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
