Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically to an automatic pressurized concrete permeation device. Background Technology

[0002] Concrete permeability testing devices are used in concrete testing to detect the impermeability of concrete. By simulating the water seepage of concrete under pressure, the quality of concrete can be accurately assessed, providing a reliable basis for engineering design and construction. This device is widely used in building engineering, road and bridge engineering, water conservancy and hydropower engineering and other fields. As long as the durability design and quality control of concrete structures are involved, it is necessary to use it to test the impermeability of concrete.

[0003] When concrete undergoes permeability testing, the large weight of the concrete causes it to fall directly into the testing equipment, leading to deformation of the equipment and breakage of the concrete sample due to violent collisions. This affects the integrity of the test sample and the accuracy of the test data. Therefore, there is an urgent need to develop an automatic pressurized concrete permeability testing device to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic pressurized concrete permeation device, which solves the problems of deformation of the testing equipment due to the impact of the heavy concrete falling directly into the testing equipment and the breakage of the concrete sample due to violent collision, thereby affecting the integrity of the test sample and the accuracy of the test data.

[0005] To achieve the above objectives, this utility model provides an automatic pressurized concrete permeation device through the following technical solution: a support frame, a mounting base for storing a test tank is fixed to one side of the top of the support frame, a water tank is provided on the other side of the top of the support frame, and the water tank is also equipped with a pressurizing component for pressurizing the test tank.

[0006] It also includes an auxiliary loading and unloading mechanism, which includes a movable disc set inside the test tank. Two sets of sealing rubber strips are embedded and installed on the outside of the movable disc. The sealing rubber strips are in close contact with the inner wall of the test tank to ensure airtightness. The bottom end of the sealing rubber strip is fixedly connected to a support rod that passes through the test tank and the bracket. A rack is installed at equal intervals on one side of the support rod. A drive assembly is fixedly connected to one side of the bottom of the bracket to drive the support rod to move vertically.

[0007] Preferably, the drive assembly includes a fixed box disposed on one side of the bottom of the bracket, a support rod passing through the inside of the fixed box, a motor fixedly connected to one side inside the fixed box, a gear plate fixedly connected to the output end of the motor, and the gear plate meshing with the rack for transmission.

[0008] Preferably, the pressurization component includes a pressurization pump located on one side of the bottom of the support. The pressurization pump is connected to the top of the water tank through a pipe to pressurize the water source in the water tank. A delivery pipe is fixed to the bottom of the water tank and is connected to the bottom of the test tank to deliver pressurized water. A drain pipe is also provided at the bottom of the test tank to discharge wastewater after the test.

[0009] Preferably, a pressure gauge is installed on one side of the top of the water tank.

[0010] Preferably, it also includes a circulation mechanism, which includes a first solenoid valve tube disposed at the bottom front of the test tank, a filter box fixedly connected to the bottom end of the first solenoid valve tube, the filter box being located at the center of the bottom of the support, two sets of metal perforated plates fixedly connected inside the filter box, a water pump being connected to the top of the filter box through a pipe fitting, a second solenoid valve tube being installed on the water pump outlet pipe, and one end of the second solenoid valve tube being connected through to the top of the water tank.

[0011] Preferably, the filter box has a door mounted on the front via a hinge, and a handle is fixedly attached to one side of the front of the door.

[0012] This invention provides an automatic pressurized concrete permeation device. Compared with the prior art, it has the following advantages.

[0013] 1. The motor drives the toothed disc to rotate, which meshes with the rack and drives the support rod to move vertically. This allows the moving disc to carry the sealing rubber strip to the top of the test tank, facilitating the placement of concrete. Subsequently, the motor reverses, and the moving disc precisely lowers the concrete to the designated position, providing stable conditions for the test. After the test, the motor runs again, and the moving disc moves upward to remove the concrete. This achieves automatic loading and unloading assistance for the test, solving the problems of concrete deformation and sample breakage caused by heavy impact on the tank, which affect the integrity and accuracy of the data.

[0014] 2. After the concrete permeability test is completed, the first solenoid valve is opened, sending the wastewater from the test tank to the filter box. Solid impurities are separated by a metal porous plate, and the water pump draws out the filtered clean water, which is then sent to the water tank through the second solenoid valve to achieve water recycling. This solves the problem of wastewater being wasted by direct discharge, avoids cement residue causing scale buildup and blockage in drainage pipes, and reduces pipe dredging and maintenance costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] First implementation method:

[0021] refer to Figure 1-3 An automatic pressurized concrete permeation device includes a support 1, a mounting base for storing a test tank 2 is fixed to one side of the top of the support 1, and a water tank 203 is provided on the other side of the top of the support 1. The water tank 203 is also equipped with a pressurizing component for pressurizing the test tank 2.

[0022] It also includes an auxiliary loading and unloading mechanism 3, which includes a movable disk 301 set inside the test tank 2. Two sets of sealing rubber strips 302 are embedded on the outside of the movable disk 301. The sealing rubber strips 302 are in close contact with the inner wall of the test tank 2 to ensure airtightness. The bottom end of the sealing rubber strips 302 is fixedly connected to a support rod 303 that passes through the test tank 2 and the bracket 1. A rack 304 is installed at equal intervals on one side of the support rod 303. A drive assembly is fixedly connected to one side of the bottom of the bracket 1 to drive the support rod 303 to move vertically.

[0023] The drive assembly includes a fixed box 305 located on one side of the bottom of the bracket 1, a support rod 303 passing through the inside of the fixed box 305, a motor 306 fixedly connected to one side inside the fixed box 305, a gear plate 307 fixedly connected to the output end of the motor 306, and the gear plate 307 meshing with the rack 304 for transmission.

[0024] The pressurization assembly includes a booster pump 202 located on one side of the bottom of the bracket 1. The booster pump 202 is connected to the top of the water tank 203 through a pipe to pressurize the water source in the water tank 203. A delivery pipe 204 is fixed to the bottom of the water tank 203. The delivery pipe 204 is connected to the bottom of the test tank 2 to deliver pressurized water. A drain pipe 201 is also provided at the bottom of the test tank 2 to discharge wastewater after the test. A pressure gauge 5 is installed on one side of the top of the water tank 203.

[0025] The motor 306 drives the gear disc 307 to rotate. The gear disc 307 transmits power by meshing with the rack 304, which in turn drives the support rod 303 to move vertically. The support rod 303 drives the moving disc 301 to the top position inside the test tank 2. At this time, the sealing rubber strip 302 on the edge of the moving disc 301 is in contact with the inner wall of the test tank 2. This state makes it easy for the operator to place the concrete on the top of the moving disc 301. Then the motor 306 drives the gear disc 307 to rotate in the opposite direction. The gear disc 307 drives the support rod 303 to move down through the rack 304, so that the concrete moves accurately with the moving disc 301 to the designated position inside the test tank 2, providing stable material placement conditions for concrete penetration testing.

[0026] After water is supplied into the water tank 203, the booster pump 202 operates to draw in outside air and deliver it into the water tank 203, thereby pressurizing the water inside the water tank 203. This causes the water inside the water tank 203 to be delivered to the test tank 2 through the delivery pipe 204 to conduct a permeation test on the concrete. The pressure gauge 5 is used to monitor the pressure inside the water tank 203, allowing the operator to automatically control the operation and stop of the booster pump 202 through the controller, thus realizing the function of automatically pressurizing and permeating the concrete.

[0027] After the concrete penetration test is completed, the motor 306 runs again to drive the toothed disc 307 to rotate. The toothed disc 307 transmits power through the rack 304, which drives the support rod 303 to move vertically upward. The support rod 303 drives the moving disc 301 to move to the top position inside the test tank 2, so that the moving disc 301 can smoothly move the concrete at the top out of the test tank 2.

[0028] This process enables automatic loading and unloading of concrete in test tank 2 for permeability testing. It solves the problems of deformation of the tank due to impact and cracking of concrete samples caused by the large weight of concrete falling directly into the test tank 2 during permeability testing. It also avoids the problem of concrete falling and damaging samples due to unstable center of gravity after the test due to increased weight from absorbing water.

[0029] Second implementation method:

[0030] The direct discharge of wastewater during concrete permeability testing leads to water waste. At the same time, cement residue contained in the directly discharged wastewater enters the drainage pipe with the water flow. Due to the hardening property of cement when it comes into contact with water, scale gradually forms on the inner wall of the pipe, causing blockage and increasing the cost of pipe dredging and maintenance.

[0031] refer to Figure 3In the second embodiment of this utility model, a circulation mechanism 4 is also included. The circulation mechanism 4 includes a first solenoid valve tube 401 disposed at the bottom front of the test tank 2. The bottom end of the first solenoid valve tube 401 is fixedly connected to a filter box 402. The filter box 402 is located at the center of the bottom of the support 1. Two sets of metal perforated plates 403 are fixedly connected inside the filter box 402. The top of the filter box 402 is connected to a water pump 404 through a pipe. A second solenoid valve tube 405 is installed on the outlet pipe of the water pump 404. One end of the second solenoid valve tube 405 is connected to the top of the water tank 203. A door 406 is installed on the front of the filter box 402 through a hinge. A handle is fixedly connected to one side of the front of the door 406.

[0032] After the concrete penetration test is completed, the first solenoid valve 401 is opened, and the wastewater generated inside the test tank 2 is transported to the filter box 402. The wastewater passes through the metal perforated plate 403 in the filter box 402 to separate and filter solid impurities such as concrete residue and debris contained in the wastewater. The filtered clean water is drawn by the water pump 404 and transported to the water tank 203 through the second solenoid valve 405, realizing the recycling of water source.

[0033] This process solves the problem of water waste caused by direct discharge of sewage in concrete permeability testing. At the same time, it avoids the problem of cement residue contained in sewage entering the drainage pipe with the water flow, causing the inner wall of the pipe to gradually scale and block due to the hardening property of cement when it comes into contact with water, thus increasing the cost of pipe dredging and maintenance. Meanwhile, opening the box door 406 allows for the collection and cleaning of cement impurities and residues separated by the metal porous plate 403.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
