AI Technical Summary
Traditional siphon rain gauges suffer from problems such as failure to generate a siphon effect or inaccurate observation data in marine environments due to shaking and turbulence.
A groove is set at the bottom of the upper cover assembly, and a measuring float with an outer diameter smaller than the inner diameter is placed inside the measuring tube. The siphon principle is used to generate a siphon when the measuring tube is full, and the float maintains the accuracy of liquid level observation in a swaying environment.
This improved the measurement accuracy of the rain gauge in marine environments, reduced measurement errors caused by device shaking, and ensured the effectiveness of liquid surface observation under tilted conditions.

Specific implementation
[0016] In order to further illustrate the technical means and its effect that the utility model adopts, below to the utility model a siphon rain gauge makes further detailed description.
[0017] As Figures 1 to 6 Shown, a siphon rain gauge, including upper cover subassembly 1, measurement cylinder 2 and lower cover subassembly 3.
[0018] Assemble upper cover subassembly 1: the bottom end surface of upper cover main body 1-1 is provided with recess 1-1-1 and heating hole 1-1-2 respectively, sets up three through holes on upper cover main body 1-1, is respectively: measurement hole 1-1-3, air hole 1-1-4 and water inlet hole 1-1-5, inserts detector 1-2 from the upper end of upper cover subassembly 1 into measurement hole 1-1-3, inserts air pipe 1-3 into air hole 1-1-4, inserts water inlet pipe 1-4 into water inlet hole 1-1-5, inserts measurement guide pipe 1-6 from the lower end of upper cover subassembly 1 into measurement hole 1-1-3, inserts heating pipe 1-7 from the lower end of upper cover subassembly 1 into heating hole 1-1-2, the outer diameter of measurement float 1-8 is less than the inner diameter of measurement guide pipe 1-6, places measurement float 1-8 in measurement guide pipe 1-6, and sealing ring I 1-5 is sleeved at the connecting place of upper cover main body 1-1 and measurement cylinder 2.
[0019] Assembling the lower cover assembly 3: according to the shape of the siphon bend 3-2, both ends of the siphon bend 3-2 are horseshoe-shaped, and the two sides of the siphon bend 3-2 are fixed with the fixing clips 3-3, the long side penetrates the lower cover body 3-1, and the short side contacts the upper end face of the lower cover body 3-1, and the sealing ring II 3-5 is sleeved at the connection between the lower cover body 3-1 and the measuring cylinder 2;
[0020] First, insert the assembled upper cover assembly 1 into the measuring cylinder 2 from the top end, then align the vertex of the siphon bend 3-2 of the assembled lower cover assembly 3 with the groove 1-1-1 at the bottom end of the upper cover body 1-1, and insert it from the lower end of the measuring cylinder 2, and finally lock and fix the upper cover body 1-1 and the lower cover body 3-1 with two support columns 3-4 and screws, and seal both ends of the measuring cylinder 2 with the sealing ring I 1-5 and the sealing ring II 3-5.
[0021] Working principle: During the precipitation process, rainwater enters the rain gauge through the water inlet pipe 1-4 of the upper cover assembly 1, and a continuously rising liquid level is formed in the rain gauge. The setting of the groove 1-1-1 ensures that the water level of the measuring cylinder 2 can fully reach the vertex of the siphon bend 3-2, and the siphon is started in time; the measuring float 1-8 in the measuring conduit 1-6 ensures that the device is not affected by shaking, and the measuring float 1-8 rises and falls with the liquid level, and the probe 1-2 continuously outputs the voltage value corresponding to the liquid level height through the height of the measuring float 1-8. When the liquid level rises to the system design height, the siphon phenomenon is started, and the water in the rain gauge is discharged outside the sensor through the siphon structure. Such a process is periodically cycled, and the liquid level represented by the output voltage is accumulated one by one in each cycle, and the precipitation amount in the entire precipitation process is finally measured. Through the processing of the precipitation amount, the rain intensity can be obtained.
