Description

Technical Field

[0001] The utility model relates to the field of engineering geological exploration, in particular to a water pressure test device for engineering geological exploration. Background Technique

[0002] Engineering geological exploration is an indispensable process in projects such as civil engineering, construction engineering, and environmental engineering. It aims to evaluate geological conditions, determine design parameters, and provide necessary data support for engineering design and construction through detailed investigation and analysis of the engineering site and its surrounding environment. Among them, tests for evaluating the permeability of soil or rock layers require the use of a water pressure test device.

[0003] In traditional water pressure test devices, a pressure pump applies water pressure, usually a manual pump or an electric pump, to control the magnitude of the water pressure. The sample cylinder is used to accommodate soil or rock samples to be tested to ensure the tightness of the test environment. The pressure sensor measures the water pressure applied to the sample to ensure the accuracy of the test. The data recording and analysis system records and analyzes the test data in real time.

[0004] However, the sample cylinder in traditional water pressure test devices is often directly fixed to the pressure pump. This single fixing method is very inconvenient when it is necessary to clean and maintain the inside of the sample cylinder. There may be residues such as soil inside, resulting in a decrease in the accuracy of the test results. Content of the Utility Model

[0007] Further, the water diversion component includes a water diversion pipe, and the water diversion pipe is fixedly connected to the side wall of the pressure pump.

[0008] Further, a fixing platform is fixedly connected to the top of the water inlet pipe, and a sliding groove is formed inside the fixing platform.

[0009] Further, a plurality of sliding platforms are slidably connected to the side wall of the fixing platform. The sliding platforms are symmetric with each other, and clamps are fixedly connected to the bottoms of the sliding platforms.

[0010] Further, fixing members are fixedly connected to the tops of the sliding platforms, and a second spring is arranged between the fixing members.

[0011] Further, two ends of the second spring are respectively fixedly connected inside the fixing members, and a connecting platform is fixedly connected to the top of the fixing platform.

[0012] Further, a connecting shaft is rotatably connected inside the connecting platform, and a clamping platform is fixedly connected to the bottom end of the connecting shaft.

[0013] Further, the clamping platform is slidably connected inside the sliding groove, and the side wall of the clamping platform is arc-shaped.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, first, the screw rod drives the push column to slide into the first fixing column.

Then, by the pulling force of the second spring on the two fixing members, the sliding platforms are pulled back to their original positions, and the water pipe can be connected to the water inlet pipe. With this structure, it is convenient for this device to introduce water source and improves the flexibility of use. Description of the Drawings

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

[0023] Referring to Figure 1 - Figure 2 , an embodiment provided by the present invention: A water pressure test device for engineering geological exploration, including a pressure pump 1, a first fixing column 2 is fixedly connected to the top of the pressure pump 1, a specimen cylinder 3 is arranged on the top of the first fixing column 2, a turntable 4 is fixedly connected to the side wall of the first fixing column 2, a screw 5 is rotatably connected inside the turntable 4, a pushing column 6 is threadedly connected to the outer wall of the screw 5, the pushing column 6 is slidably connected inside the first fixing column 2, a sliding column 7 is slidably connected inside the first fixing column 2, a second fixing column 8 is fixedly connected to the top of the first fixing column 2, a first spring 9 is arranged between the second fixing column 8 and the sliding column 7, a plurality of clamping plates 10 are rotatably connected inside the second fixing column 8, and a water diversion assembly is arranged on the side wall of the pressure pump 1, and the water diversion assembly is used to guide water flow into the pressure pump 1.

[0024] Specifically, rotate the screw 5 to make it rotate inside the turntable 4. The screw 5 drives the pushing column 6 to slide along the inside of the first fixing column 2 through its threaded connection with the pushing column 6. The movement of the pushing column 6 further pushes the sliding column 7. After the sliding column 7 receives the thrust, it will slide into the second fixing column 8 and push a plurality of clamping plates 10. As the clamping plates 10 move, they will start to rotate inside the second fixing column 8, thereby releasing the clamping of the specimen cylinder 3. In this process, the setting of the first spring 9 also plays a key role. After the specimen cylinder 3 is disassembled, the first spring 9 will make the device return to its original fixed state, thereby re-fixing the specimen cylinder 3. This structural design makes the disassembly and assembly process of the specimen cylinder 3 rapid and efficient. This design not only improves the convenience of disassembly and assembly, but also ensures that the specimen cylinder 3 can be easily cleaned and maintained, preventing the influence of internal residual soil and other debris on the accuracy of the test results. In this way, the operator can better maintain the equipment and ensure the accuracy of the test results.

[0025] Referring to Figure 3, the drainage component includes a water diversion pipe 11, the water diversion pipe 11 is fixedly connected to the side wall of the pressure pump 1, the top of the water diversion pipe 11 is fixedly connected with a fixing platform 12, a chute 20 is opened inside the fixing platform 12, a plurality of sliding platforms 13 are slidably connected to the side wall of the fixing platform 12, the sliding platforms 13 are symmetrical to each other, clamps 14 are fixedly connected to the bottoms of the sliding platforms 13, fixing members 15 are fixedly connected to the tops of the sliding platforms 13, a second spring 16 is arranged between the fixing members 15, and both ends of the second spring 16 are fixedly connected to the inside of the fixing members 15. A connecting platform 17 is fixedly connected to the top of the fixing platform 12, a connecting shaft 18 is rotatably connected to the inside of the connecting platform 17, a clamping platform 19 is fixedly connected to the bottom end of the connecting shaft 18, the clamping platform 19 is slidably connected to the inside of the chute 20, and the side wall of the clamping platform 19 is arc-shaped.

[0026] Specifically, rotate the connecting shaft 18 to make it rotate inside the connecting platform 17. The rotation of the connecting shaft 18 will drive the clamping platform 19 at the bottom to rotate correspondingly in the chute 20. The arc-shaped surface of the clamping platform 19 will push the clamping platform 19 to slide along the side wall of the fixing platform 12. During this process, the clamps 14 at the bottom of the clamping platform 19 will open relatively, so that the water pipe can be smoothly connected to the water diversion pipe 11. After completing the above steps, through the pulling force applied by the second spring 16, the two fixing members 15 will move, and then drive the sliding platforms 13 to reset. At this time, the connection between the water pipe and the water diversion pipe 11 will be stably completed. This structural design not only simplifies the operation process of water source introduction, but also significantly improves the flexibility and convenience of the device.

[0027] Working principle: When it is necessary to disassemble the sample cylinder 3 from this device, rotate the screw rod 5 to make it rotate inside the turntable 4. The screw rod 5 drives the push column 6 to slide into the inside of the first fixing column 2 through the threaded connection relationship of the push column 6. The push column 6 then pushes the sliding column 7. After being stressed, the sliding column 7 slides into the inside of the second fixing column 8 and pushes a plurality of clamping plates 10. After being stressed, the clamping plates 10 can rotate inside the second fixing column 8 to release the clamping of the sample cylinder 3, and the sample cylinder 3 can be re-fixed through the arrangement of the first spring 9. With this structure, the rapid disassembly and assembly of the sample cylinder 3 can be realized, and it can be cleaned and maintained to avoid the influence of residual soil and other sundries inside on the accuracy of the test results. When it is necessary to connect the water pipe to the water diversion pipe 11 to introduce water source into the pressure pump 1, rotate the connecting shaft 18. The rotation of the connecting shaft 18 inside the connecting platform 17 drives the clamping platform 19 at its bottom to rotate inside the chute 20. The arc-shaped surface of the clamping platform 19 is used to push the clamping platform 19 to make the clamping platform 19 slide on the side wall of the fixing platform 12. At this time, the clamps 14 at the bottom of the clamping platform 19 can open relatively. Then, by the pulling force of the second spring 16 on the two fixing members 15, the sliding platforms 13 are pulled to reset, and the water pipe can be connected to the water diversion pipe 11. With this structure, it is convenient for this device to introduce water source and improves the flexibility of use.
