[0020] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, this utility model provides a water permeability coefficient test water supply device, including a water storage tank 1. A heating mechanism 3 is arranged on the outer surface of the water storage tank 1. A stirring mechanism 4 is arranged on the top of the water storage tank 1. The heating mechanism 3 includes a mounting plate 301, a test box 309 and a temperature sensor 312. A first motor 302 is arranged at a position near the center of the bottom of the mounting plate 301. The output end of the first motor 302 penetrates through the bottom of the mounting plate 301 and extends upward. The output end of the first motor 302 is fixedly connected with a rotating rod 303. The top of the rotating rod 303 is fixedly connected with a rotating plate 304. A plurality of heating blocks 305 are arranged on the top of the rotating plate 304. A water storage tank 306 is fixedly installed at a position near the corner of the top of the mounting plate 301. A water delivery pipe 307 is fixedly communicated with the outer surface of the water storage tank 306. One end of the water delivery pipe 307 penetrates through the outer surface of the water storage tank 1 and extends to one side. A first water pump 308 is arranged on the outer surface of the water delivery pipe 307. A water outlet pipe 310 is fixedly communicated with the outer surface of the test box 309. One end of the water outlet pipe 310 penetrates through the outer surface of the water storage tank 1 and extends to one side. The bottom of the test box 309 is fixedly installed with the top of the mounting plate 301. A second water pump 311 is arranged on the outer surface of the water outlet pipe 310. The outer surface of the temperature sensor 312 is fixedly installed with the outer surface of the water storage tank 1.

[0023] The effect achieved by the entire Embodiment 1 is that when using this water permeability coefficient test water supply device, first, an appropriate amount of water needs to be added to the water storage tank 306. Subsequently, the first water pump 308 is started, and the water in the water storage tank 306 is pumped out through the first water pump 308 and conveyed to the water storage tank 1 through the water delivery pipe 307. While the water enters the water storage tank 1, the heating block 305 is started to start heating the bottom of the water storage tank 1. At the same time, the first motor 302 at the bottom of the mounting plate 301 is started, and its output end will drive the rotating rod 303 to rotate. As the rotating rod 303 rotates, the rotating plate 304 will also rotate accordingly, so that the heating block 305 can uniformly heat the water storage tank 1 during the rotation process, ensuring the uniformity of the water temperature, thus ensuring the constancy of the water temperature during the test process and improving the accuracy of the test results. During the heating process, the temperature sensor 312 will continuously and real-time monitor the temperature inside the water storage tank 1. When the temperature in the water storage tank 1 reaches the preset value, the temperature sensor 312 will quickly send a signal to the external controller. After receiving the signal, the external controller will immediately turn off the heating block 305 to ensure that the water temperature in the water storage tank 1 remains at the preset value. Subsequently, when the water temperature in the water storage tank 1 reaches and stabilizes at the preset value, the second water pump 311 is started. The second water pump 311 will pump out the water inside the water storage tank 1 through the water outlet pipe 310 and convey it to the test box 309 for subsequent use in the water permeability coefficient test. Under the action of the heating mechanism 3, the water required for the test can be heated and continuously maintained within the preset water temperature range. Through temperature control, not only the accuracy of the test is improved, but also the reliability of the test results is guaranteed.

[0024] Embodiment 2, as Figures 1 - 4 shown, the stirring mechanism 4 includes a second motor 401. The second motor 401 is installed on the top of the water storage tank 1. The output end of the second motor 401 penetrates the top of the water storage tank 1 and extends downward. The output end of the second motor 401 is fixedly connected with a connecting rod 402. A plurality of stirring blades 403 are fixedly connected in an array on the outer surface of the connecting rod 402. A fixing column 2 is fixedly installed on the outer surface of the water storage tank 1. The top of the fixing column 2 is fixedly connected with the top of the mounting plate 301.

[0025] The effect achieved by the entire Embodiment 2 is that when using this device, by starting the second motor 401, the output end of the second motor 401 will drive the connecting rod 402 to rotate. As the connecting rod 402 rotates, the stirring blades 403 will rotate at high speed. Such high-speed rotating stirring blades 403 can fully stir the heating water, ensure the uniformity of water heating, and avoid test errors caused by problems such as local overheating or uneven temperature.

[0026] Working principle: When in use, start the first water pump 308 to pump out the water in the water storage tank 306 and transport the water to the water storage tank 1 through the water delivery pipe 307. While the water enters the water storage tank 1, start the heating block 305 to heat the bottom of the water storage tank 1. At the same time, start the first motor 302 to drive the rotating rod 303 to rotate. As the rotating rod 303 rotates, the heating block 305 can evenly heat the water storage tank 1 during the rotation process. During the heating process, the temperature sensor 312 monitors the temperature inside the water storage tank 1 in real time. When the temperature in the water storage tank 1 reaches the preset value, the temperature sensor 312 will quickly send a signal to the external controller. After receiving the signal, the external controller will immediately turn off the heating block 305 to ensure that the water temperature in the water storage tank 1 remains at the preset value. Subsequently, by starting the second motor 401, the output end of the second motor 401 will drive the connecting rod 402 to rotate. As the connecting rod 402 rotates, the stirring blade 403 will rotate at high speed. This high-speed rotating stirring blade 403 can fully stir the heating water. Finally, start the second water pump 311, and the second water pump 311 will pump out the water inside the water storage tank 1 through the water outlet pipe 310 and transport it to the test box 309 for subsequent use in the permeability coefficient test.

[0027] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
