Description

Technical Field

[0001] The present application relates to the field of design of water injection devices for permeameters, and in particular, to a water injection device for permeameters. Background Art

[0002] The common permeameter is a testing instrument that combines the negative pressure method and the weight method. It measures the amount of water flowing out of the soil and the number of vibrations in a certain period of time, calculates the permeability coefficient, and thus determines the permeability of the soil.

[0003] Since a large amount of water needs to be added to the permeameter when it is used, and in order to determine the amount of water added, water is usually injected into a graduated tube for reading, and the water in the graduated tube then flows into the permeameter. In order for all the water in the graduated tube to flow into the permeameter, the lower end of the graduated tube needs to be higher than the permeameter, and the length of the graduated tube is usually long, so users often need to lift a large amount of water to the upper end of the graduated tube at a higher height to inject water. The water injection process is laborious, and users are at risk of falling and getting injured when climbing high. Summary of the invention

[0030] A permeameter water injection device includes: a graduated tube 1, a water delivery component and a water pump 2. A group of graduations are formed on the outer wall of the graduated tube 1, which is convenient for the user to observe the volume of water in the graduated tube 1. The lower end of the graduated tube 1 is connected to the permeameter 12 through a hose. The water pump 2 uses an existing centrifugal pump, and the water delivery component forms a water inlet and a water outlet. The water inlet is connected to the output end 6 of the water pump 2, and the water outlet is connected to the upper end of the graduated tube 1. The input end 5 of the water pump 2 is connected to an external water source. The water pump 2 is used to pump water from the external water source, and then transport the water upward to the upper end of the graduated tube 1 along the water delivery component, and finally the water flows into the permeameter 12 from the lower end of the graduated tube 1. The external water source can specifically be one of a pool, a water pipe and a water tank.

[0031] Specifically, multiple groups of calibrated tubes 1 are provided, five groups in this embodiment, and the water supply assembly forms five groups of water outlets corresponding to the calibrated tubes 1 one by one. Therefore, the five groups of calibrated tubes 1 can simultaneously inject water into five permeameters 12, thereby improving the user's detection efficiency for a large number of samples.

[0032] In another embodiment, the water delivery assembly includes: a porous valve 3 and a pipeline 4. The input end 5 of the porous valve 3 forms a water inlet, and the input end 5 of the porous valve 3 is fixedly connected to the output end 6 of the water pump 2 by bolts. The porous valve 3 forms multiple output ends 6, and in this embodiment, there are five output ends 6, and the five output ends 6 can be opened and closed in sequence. The pipeline 4 is selected as a hose, which is convenient for the user to bend at will. Multiple groups of pipelines 4 are set, and five groups are selected in this embodiment. One end of the five groups of pipelines 4 forms a water outlet, and the water outlet is connected to the upper end of multiple groups of calibrated tubes 1 in a one-to-one correspondence. The other end of the five groups of pipelines 4 is connected to the output ends 6 of the five porous valves 3 in a one-to-one correspondence through a pipe joint. The porous valve 3 can choose to inject the water pumped by the water pump 2 into one group, two groups, three groups, four groups and five groups of pipelines 4, so that the user can control the porous valve 3 to inject water into any number of pipelines 4, so that when the sample does not occupy all five permeameters 12, the water supply to the unused permeameter 12 is suspended to avoid water waste.

[0033] Specifically, the porous valve 3 includes: a valve shell and a valve core 7. The interior of the shell forms a cylindrical chamber, and the valve core 7 is a fan-shaped cylinder. The valve core 7 fills the remaining space in the cylindrical chamber to form a fan-shaped cavity, and the water pumped by the water pump 2 enters the fan-shaped cavity from the input end 5 of the porous valve 3. The valve core 7 can rotate continuously relative to the axis of the cylindrical cavity. When the valve core 7 is at the initial angle, the fan-shaped cavity is connected to the input end 5. At this time, the water is retained in the fan-shaped cavity, and the porous valve 3 suspends the water supply to the five groups of pipes 4. When the valve core 7 rotates to the full opening angle, that is, 150 degrees, the fan-shaped cavity connects the input end 5 with the four output ends 6 one by one, and the porous valve 3 supplies water to the four groups of pipes 4 one by one. When the valve core 7 rotates to the full opening angle, that is, 150 degrees, the fan-shaped cavity is connected to the input end 5 and all five output ends 6, and the porous valve 3 supplies water to all five groups of pipes 4. The user can control the water supply of five pipes 4 by rotating a valve core 7, which is easy to operate.

[0034] Specifically, the valve housing includes: a valve cover 8 and a valve bottom 9. The valve cover 8 is butted against the valve bottom 9 and is detachably connected by bolts, so that the user can replace the valve core 7 clamped between the valve cover 8 and the valve bottom 9.

[0035] Specifically, the valve cover 8 covers a plane of the cylindrical chamber, and the material of the valve cover 8 is a light-transmitting plastic, so that the user can observe the number of output ends 6 from which water flows out of the porous valve 3 when rotating the valve core 7 .

[0036] Specifically, the porous valve 3 further includes a rotating handle 10. The valve cover 8 forms a through hole coaxial with the cylindrical chamber, one end of the rotating handle 10 is inserted into the through hole, the end of the rotating handle 10 is fixed to the side of the valve core 7 facing the valve cover 8 by bolts, and the rotating handle 10 is rotatably connected to the through hole, so that the user can rotate the valve core 7 to any angle by holding the rotating handle 10 to control the water supply of the porous valve 3 to the five groups of pipes 4.

[0037] Specifically, it also includes: water valves 11. Multiple groups of water valves 11 are provided, and in this embodiment, five groups are provided, and the five groups of water valves 11 are connected to the lower parts of the five groups of pipes 4 in a one-to-one correspondence. When the permeameter 12 between two permeameters 12 in use is damaged and needs to be replaced, the user can close the water valve 11 on the pipe 4 corresponding to the damaged permeameter 12, and the porous valve 3 stops supplying water to the corresponding pipe 4. After the water in the calibrated tube 1 is drained, the user can replace the damaged permeameter 12.
