Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrological testing, in particular to a steady-flow siphon device. Background Art
[0002] Sediment content determination is an important indicator in hydrological testing. The conventional determination method is to dry, weigh and calculate the sediment content. The current sample collection and preparation method is to collect a certain volume of sample and place it in a container for a specified time (no less than 3 days in flood season and no less than 5 days in non-flood season). After standing, use a pipette or silicone hose to siphon off the upper clear liquid. In order to avoid disturbing the bottom sand layer, the siphoning process requires manual adjustment of the siphon position and siphon water volume to avoid disturbing the lower water body; the lower water needs to be replaced with an ear bulb to absorb, and as much water sample as possible is removed under the premise of avoiding disturbing the deposited sand. Finally, the remaining small amount of water-sand mixture is transferred to a beaker for drying and weighing.
[0003] During the sample processing process, since no major disturbance of the water body can occur, the siphon position and siphon flow rate need to be manually controlled, which makes the sample processing work quite time-consuming and labor-intensive, and places strict operating requirements on the sample processing personnel. Any carelessness will cause the loss of sand samples, which will affect the accuracy of the measurement results.
[0004] To this end, we propose a steady-flow siphon device. Summary of the invention
[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a steady-flow siphon device.

[0008] A siphon tube is provided, an overflow hole is opened on the tube wall of the siphon tube, a water outlet pipe is coaxially provided in the siphon tube, the siphon tube is then placed in the clear liquid to be removed, the siphon air bag is squeezed, and the clear liquid in the sample is removed by the siphon phenomenon. The overflow hole on the tube wall of the siphon tube can avoid water disturbance caused by excessive siphon flow rate, and avoid the problem of sand sample loss due to water disturbance. The depth of the siphon tube entering the water body can be adjusted by an adjusting frame to be removed, so as to achieve fixed-layer siphoning, eliminate the step of manually adjusting the position of the straw at any time for the siphon, and save manpower.
[0009] It is further defined that the bottom end of the water outlet pipe is located at the bottom of the siphon tube, and a water outlet groove is arranged on the bottom circumference of the water outlet pipe; by providing a water outlet groove on the bottom circumference of the water outlet pipe for discharging water instead of directly using the bottom opening of the water outlet pipe as the water outlet, such an arrangement can further control the siphon flow rate to make it slower, thereby improving the flow stabilization effect.
[0010] It is further defined that a regulating water valve is also connected to the water hose; by setting the regulating water valve, the siphon flow rate can also be controlled to further enhance the flow stabilization effect of the device.
[0011] It is further defined that the fixing plate is in the shape of a long strip, both ends of the fixing plate are fixedly arranged on the top of the siphon tube, and a fixing hole for the water outlet pipe to pass through is opened in the middle of the fixing plate; setting a long strip of fixing plate to set the water outlet pipe and the siphon tube coaxially has a simple structure and is easy to manufacture.
[0012] It is further defined that the adjusting frame includes a holding ring, a plurality of connecting rods and a clamping screw. The inner diameter of the holding ring and the outer diameter of the siphon tube are clearance-matched. A locking hole matching the clamping screw is provided on the holding ring. A plurality of connecting rods are evenly spaced and arranged on the circumference of the holding ring. The connecting rods are used to fix the holding ring. The siphon tube is inserted into the holding ring. By tightening the clamping screw, the end of the clamping screw presses the outer wall of the siphon tube to fix the height of the siphon tube. The fixing is firm and not easy to slip.
[0013] It is further defined that the aperture of the overflow hole gradually decreases from top to bottom; such an arrangement of the overflow hole can ensure a relatively consistent water inlet from top to bottom due to different pressures at different water depths.
[0014] The beneficial effect of the utility model is that by providing a siphon tube and opening an overflow hole on the siphon tube from top to bottom, the water flow entering the outlet pipe can be greatly reduced, thereby controlling the siphon flow rate, avoiding the disturbance of the water body caused by excessive siphon flow rate, and avoiding the loss of sand samples.
