Abstract
Description
Technical Field
[0001] This utility model relates to a self-leveling anti-permeability instrument, and more specifically, it relates to a self-leveling anti-permeability instrument. Background Technology
[0002] A self-leveling permeability tester is an instrument used to test the permeability resistance of self-leveling materials. This instrument has wide applications in fields such as construction and water conservancy, especially in situations where it is necessary to assess the ability of self-leveling materials to resist water penetration.
[0003] The working principle of a self-leveling permeability tester is based on either electrochemical or pressure osmosis principles. A permeability tester based on the pressure osmosis principle uses a sealed container and a connecting pipeline system to apply pressure with a water pump, causing pressurized water to permeate upwards through the test specimen in the mold, thereby determining the permeability performance of the specimen and calculating its permeability grade.
[0004] Existing self-leveling permeability testers sometimes cause debris to fall into the mold and settle at the bottom when the self-leveling specimen is placed inside. The presence of debris alters the contact state between the specimen and the mold, thus affecting the specimen's permeability performance. Furthermore, the bottom of the mold is quite deep, making manual cleaning inconvenient and increasing the difficulty of cleaning.
[0005] Therefore, a new solution is needed to address this problem. Utility Model Content
[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a self-leveling anti-permeability instrument. A motor drives the chassis to rotate, concentrating and throwing away debris originally scattered at the bottom of the mold to the chassis edge. This makes it easier for workers to clean the debris from the edge of the chassis. Furthermore, the diameter of the chassis is the same as the inner diameter of the mold, preventing debris from falling to the bottom of the mold, i.e., below the chassis. Simultaneously, when the cylinder pushes the chassis upwards, it approaches the mold's outlet, allowing workers to clean the self-leveling debris from the chassis at the mold's outlet without needing to penetrate deep into the mold, thus reducing cleaning difficulty.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a self-leveling anti-permeability instrument, comprising a body, a test mold at the upper end of the body, a base plate movably disposed in the lower part of the inner cavity of the test mold, a cover plate at the rear side of the upper end of the body, a drain pipe and a water supply pipe on the right side of the body, a fixing plate fixedly installed at the left end of the body, a cylinder fixedly installed at the upper end of the fixing plate, a movable plate fixedly installed at the output end of the cylinder, a rotating shaft movably inserted and connected at the middle side of the upper end of the movable plate, the rotating shaft passing through the bottom of the body and extending into the test mold and fixedly connected to the base plate, a motor fixedly installed at the lower end of the rotating shaft, the motor fixedly connected to the lower end of the movable plate, a power button at the left side of the front end of the body, and a control panel at the middle side of the front end of the body.
[0008] The present invention is further configured such that four support legs are fixedly installed at the lower end of the body.
[0009] The present invention is further configured such that: the chassis is circular in shape, and the diameter of the chassis is the same as the inner diameter of the mold.
[0010] The present invention is further configured such that a drain valve is provided on the right side of the front end of the machine body.
[0011] In summary, this utility model has the following beneficial effects:
[0012] 1. The chassis is rotated by a motor, and the debris originally scattered at the bottom of the mold is concentrated and thrown away to the edge of the chassis. This makes it easier for workers to clean the debris from the edge of the chassis. The diameter of the chassis is the same as the inner diameter of the mold, so the debris will not fall to the bottom of the mold, i.e., below the chassis. At the same time, when the cylinder pushes the chassis upward, it is close to the exit of the mold, which makes it easy for workers to clean the self-leveling debris on the chassis at the exit of the mold without having to go deep into the mold, thus reducing the difficulty of cleaning.

[0020] A self-leveling impermeable device, such as Figures 1 to 2As shown, the device includes a body 1, a test mold 2 at its upper end, a base 3 movably mounted in the lower part of the inner cavity of the test mold 2, a cover plate 4 at the rear of the upper end of the body 1, a drain pipe 5 and a water supply pipe 6 on the right side of the body 1, a fixing plate 7 fixedly mounted on the left end of the body 1, a cylinder 8 fixedly mounted on the upper end of the fixing plate 7, a movable plate 9 fixedly mounted on the output end of the cylinder 8, a rotating shaft 10 movably inserted through the middle of the upper end of the movable plate 9, the rotating shaft 10 passing through the bottom of the body 1 and extending into the test mold 2 and fixedly connected to the base 3, the base 3 being circular in shape, the diameter of the base 3 being the same as the inner diameter of the test mold 2, and the lower end of the rotating shaft 10... A motor 11 is fixedly installed and connected to the lower end of the movable plate 9. A power button 12 is located on the left side of the front end of the main body 1, and a control panel 13 is located on the center side of the front end of the main body 1. The power button 12 is a key component for starting and stopping the self-leveling permeability tester. Pressing the power button 12 connects the instrument to the power supply and begins initialization, preparing it for subsequent testing. After completing the test, pressing the power button 12 safely shuts down the instrument, cutting off the power and avoiding energy waste and safety hazards. The control panel 13 is equipped with a display screen to show various data during the testing process in real time, such as current pressure and test time. This data helps users understand the test progress and the status of the specimen, allowing for timely adjustments to test parameters or necessary interventions.
[0021] like Figure 1 As shown, four support legs 14 are fixedly installed at the lower end of the machine body 1, and a drain valve 15 is provided on the right side of the front end of the machine body 1. The support legs 14 provide support and stability to the machine body 1, and the drain valve 15 drains the water in the mold 2, making it easier to remove the specimen from the mold 2.
[0022] Working principle: A movable base 3 is set at the bottom of the mold 2. After the test specimen is tested for impermeability within the mold 2, it is removed from the mold 2. The specific impermeability working principle of the specimen is based on existing technology. A movable base 3 is set at the bottom of the mold 2. After the test specimen is tested for impermeability within the mold 2, it is removed from the mold 2. The cylinder 8 is a commonly used pneumatic actuator that can convert the pressure energy of gas into mechanical energy, thereby driving the load to move linearly. The cylinder 8 drives the connected rotating shaft 10 to move upward, and the rotating shaft 10 drives the base 3. As it moves upwards, it approaches the exit of the test mold 2. Simultaneously, the motor 11 drives the chassis 3 to rotate. The debris originally scattered at the bottom of the test mold 2 and on the chassis 3 is concentrated and thrown away to the edge of the chassis 3, making it easier for workers to clean the debris from the edge of the chassis 3. Furthermore, the diameter of the chassis 3 is the same as the inner diameter of the test mold 2, so the debris will not fall to the bottom of the test mold 2, i.e., below the chassis 3. At the same time, as the cylinder 8 pushes the chassis 3 upwards, it approaches the exit of the test mold 2, allowing workers to clean the self-leveling debris on the chassis 3 at the exit of the test mold 2 without having to go deep into the interior of the test mold 2, thus reducing the difficulty of cleaning.
