Description

Technical Field

[0001] The utility model relates to the technical field related to rockfill dam filling density detection, in particular to a rockfill dam filling density detection device. Background Art

[0002] The density test of rockfill dam is carried out at the height of the sand filling cylinder mouth. Sand is filled into the sand filling cylinder until the distance to the top of the cylinder does not exceed about 15mm. The mass m1 of the sand in the cylinder is weighed to an accuracy of 1g. Each subsequent calibration and test should maintain the mass of the sand filled at the same height. The switch is turned on to align the sand flow hole at the bottom of the sand filling cylinder, the circular hole at the upper end of the conical funnel and the circular hole in the center of the switch iron plate up and down to allow the sand to flow out freely, and the volume of the flowing sand is equal to the volume of the test pit dug at the construction site (or equal to the volume of the calibration tank). Then the switch is turned off. This step cannot be omitted. It is to keep the measured sand in the state of measurement in order to accurately obtain the volume of the measured sand.

[0003] The existing conical funnel used for testing the filling density of rockfill dams is often blocked because the sand is in a measuring flow state, which affects the accuracy of the sand filling tube and the sand loading quality, resulting in deviations in the testing of the filling density of rockfill dams.

The connecting ring 2 can be movably connected to the connection between the sand filling cylinder 4 and the lower sand cylinder 1, and is tightened. The switch on the sand filling cylinder 4 is turned on to allow the sand to flow into the middle hole of the substrate. When the sand in the lower sand cylinder 1 stops flowing down, the switch is turned off, the sand filling cylinder is removed, and the mass of the sand in the measuring cylinder is weighed;

[0028] Among them, a threaded bottom 3 is installed at the connection between the lower sand cylinder 1 and the sand filling cylinder 4, a funnel cylinder 5 is fixed at the bottom end of the sand filling cylinder 4, a circular hole 6 is fixedly connected to the top of the funnel cylinder 5, a sand lowering spiral rod 7 is movably installed inside the circular hole 6, and a handle 8 is fixedly connected to the top of the sand lowering spiral rod 7.

The funnel cylinder 5 inside the sand filling cylinder 4 can flow the measured sand (m5) into the lower sand cylinder 1, and the measured sand spirally enters the top of the funnel cylinder 5 through the circular hole 6. The user manually pushes the handle 8, and the lower sand spiral rod 7 on the handle 8 brings the measured sand spiral into the circular hole 6 to avoid excessive measurement sand being blocked in the circular hole 6 and the top of the funnel cylinder 5.

The threaded strip 9 on the sand lowering spiral rod 7 is threadedly connected to the shaft ring 10. The measured sand inside the sand filling cylinder 4 enters the circular hole 6 and the funnel cylinder 5 along with the threaded strip 9 on the sand lowering spiral rod 7. The measured sand can be transported to the lower sand cylinder 1. The user can manually twist the handle 8 to drive the threaded strip 9 on the sand lowering spiral rod 7 to rotate and add sand. When the measured sand inside the transparent funnel cylinder 5 and the lower sand cylinder 1 is filled with, the user can stop twisting the handle 8. When the circular hole 6, the funnel cylinder 5 and the lower sand cylinder 1 are blocked during the sand filling process, the user can continue to twist the handle 8 to drive the threaded strip 9 on the sand lowering spiral rod 7 to perform anti-blocking rotation and addition.

When the transparent funnel tube 5 and the lower sand tube 1 are filled with measured sand, the handle 8 can be stopped and twisted. The sealing plate 11 is screwed to the circular hole 6, the funnel tube 5 and the tube mouth of the lower sand tube 1 along with the threaded strip 9 on the sand lowering spiral rod 7 to perform sealing.
