Abstract
Description
Technical Field
[0001] This utility model relates to the field of simulation experiments, and more specifically, to a simulation experimental device for seepage in rock fractures. Background Technology
[0002] Rock fracture seepage simulation experimental devices are specialized equipment used to simulate and study the seepage characteristics in rock fractures. These devices are typically designed for use in geological engineering, geotechnical engineering, and related scientific research fields to gain a deeper understanding of the seepage behavior in fractured rock masses. The simulation device injects fluid (water or other liquids) through an injection system to simulate the seepage process of groundwater flow.
[0003] However, most current rock fracture seepage simulation experimental devices have the following problems:
[0004] I. In existing rock fracture seepage simulation experimental devices, during the experiment, water in the rock sample easily traps some impurities. When the experimental equipment detects the water in the fluid through sensors, the impurities in the water can easily clog the outlet pipe and scratch the components inside the pipe, making it inconvenient to filter the impurities in the water.
[0005] II. Existing rock mass fissure seepage simulation experimental devices mostly involve filling the equipment with liquid during seepage simulation. The liquid then flows through the fissures of the rock mass sample to simulate seepage. When installing the sample, the support is mostly fixed by welding or other methods. The size of the support is fixed, and the size of the sample that can be placed is fixed, making it inconvenient to disassemble the support to replace and install samples of different sizes.
[0006] Therefore, we made improvements and proposed a simulation experimental device for seepage in rock fractures. Utility Model Content
[0007] The purpose of this invention is to address the current problems of inconvenience in filtering impurities in water and inconvenience in disassembling the support to replace and install samples of different sizes.
[0008] To achieve the above objectives, the present invention provides the following technical solution:
[0009] A rock mass fracture seepage simulation experimental device was developed to improve the above-mentioned problems.
[0010] The application is as follows:
[0011] The device includes a housing and a mounting frame. The mounting frame is housed within the housing, and a support plate and a sealing gasket are fixedly connected within it. A rock sample is placed within the mounting frame. A motor is fixedly connected to the housing, and a reciprocating screw is fixedly connected to the motor's output shaft. The reciprocating screw is rotatably connected to the mounting frame. A moving block is threaded onto the reciprocating screw, and a scraper is fixedly connected to the moving block. A slider is fixedly connected to the scraper, and a sliding rod is slidably connected to the upper limit of the slider. The sliding rod is fixedly connected to the mounting frame. A filter plate is fixedly connected to the housing. A collection box is fixedly connected to the housing, and a sealing plate is bolted to the collection box. A guide plate is fixedly connected to the housing, and a discharge pipe is fixedly connected to the guide plate. A flow rate sensor is installed on the discharge pipe, and a control panel is connected to the flow rate sensor via a cable. The control panel is mounted on the housing. A discharge pipe is fixedly connected to the housing, and a mounting box is fixedly connected to the housing, containing a spring.
[0012] As a preferred technical solution of this application, the inner side end face of the fixing frame is inclined, and the trays are symmetrically distributed inside the fixing frame.
[0013] As a preferred technical solution of this application, the output shaft of the motor is fixedly connected to the center of one end of the reciprocating lead screw, and the top surface of the moving block is in contact with the inner top surface of the fixed frame.
[0014] As a preferred technical solution of this application, the center line of the moving block and the center line of the slider are at the same horizontal line, and the bottom end surface of the scraper is in contact with the top end surface of the filter plate.
[0015] As a preferred technical solution of this application, the filter plate has an inverted "U" shaped cross-section, and the collection boxes are symmetrically distributed on the left and right sides of the device housing.
[0016] As a preferred technical solution of this application, the other end of the spring is fixedly connected to a limiting plate, a clamping plate is fixedly connected to the limiting plate, a pull rod is fixedly connected to the limiting plate, and the height of the bottom end face of the feeding tube is greater than the height of the bottom end face inside the device housing.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] In the scheme of this application:
[0019] 1. Equipped with a reciprocating screw; during seepage, it can filter impurities in the liquid through the filter plate, preventing impurities from affecting the output detection effect. To prevent material from clogging the filter plate, the motor can be turned on to drive the reciprocating screw to rotate. The reciprocating screw can drive the moving block to move back and forth. When the moving block drives the scraper to move, the scraper can move smoothly through the sliding support of the slider on the slide rod. The scraper can scrape off the filtered impurities and clean them into the collection box, preventing impurities from clogging and affecting the filtration effect.
[0020] 2. Equipped with a retaining plate; when it is necessary to disassemble the fixing frame to replace it with a different size, the pull rod on both sides of the mounting box can be pulled. The pull rod drives the limiting plate to move, and the limiting plate can compress the spring. At the same time, the limiting plate can remove the retaining plate from the fixing frame. After the fixing frame is unobstructed, it can be removed for disassembly and replacement. When fixing the replacement fixing frame, release the pull rod. Under the push of the spring, the limiting plate and the retaining plate will return to their original positions. The retaining plate will engage in the fixing frame, which can limit and fix it, making it convenient to replace fixing frames with different hole sizes. Attached Figure Description

[0033] like Figure 1-5As shown, this embodiment proposes a rock mass fracture seepage simulation experimental device, including a device shell 1 and a fixing frame 2. The fixing frame 2 is installed inside the device shell 1, and a support plate 3 is fixedly connected inside the fixing frame 2. A sealing gasket 4 is fixedly connected inside the fixing frame 2, and a rock mass sample 5 is placed inside the fixing frame 2. A motor 6 is fixedly connected to the device shell 1, and a reciprocating screw 7 is fixedly connected to the output shaft of the motor 6. The reciprocating screw 7 is rotatably connected inside the fixing frame 2. A moving block 8 is threadedly connected to the reciprocating screw 7, and a scraper 9 is fixedly connected to the moving block 8. A slider 10 is fixedly connected to the scraper 9, and a sliding rod 11 is slidably connected to the upper limit of the slider 10. Rod 11 is fixedly connected inside the fixed frame 2. Filter plate 12 is fixedly connected inside the device housing 1. Collection box 13 is fixedly connected to the device housing 1. Sealing plate 14 is bolted to the collection box 13. Guide plate 15 is fixedly connected inside the device housing 1. Feed pipe 16 is fixedly connected to the guide plate 15. Flow rate detection sensor 17 is installed on the feed pipe 16. Flow rate detection sensor 17 is connected to control panel 18 via cable. Control panel 18 is installed on the device housing 1. Discharge pipe 19 is fixedly connected to the device housing 1. Mounting box 20 is fixedly connected to the device housing 1. Spring 21 is fixedly connected inside the mounting box 20.
[0034] Example 2:
[0035] The solution in Example 1 will be further described below with reference to its specific working method.
[0036] like Figure 2 As shown, in a preferred embodiment, based on the above method, the inner side end face of the fixing frame 2 is inclined, and the trays 3 are symmetrically distributed in the fixing frame 2, which can ensure that the inclined surface in the fixing frame 2 can guide the added water.
[0037] like Figure 2 As shown, in a preferred embodiment, based on the above method, the output shaft of the motor 6 is further fixedly connected to the center of one end of the reciprocating lead screw 7, and the top surface of the moving block 8 is in contact with the inner top surface of the fixed frame 2, which can ensure that when the moving block 8 moves, it can move smoothly by being supported by the contact of the inner top surface of the fixed frame 2.
[0038] like Figure 4 As shown, in a preferred embodiment, based on the above method, the center line of the moving block 8 and the center line of the slider 10 are at the same horizontal line, and the bottom surface of the scraper 9 is in contact with the top surface of the filter plate 12, which can ensure that the moving block 8 and the slider 10 can smoothly drive the scraper 9 to move.
[0039] like Figure 3As shown, in a preferred embodiment, based on the above method, the filter plate 12 has an inverted "U" shaped cross section, and the collection box 13 is symmetrically distributed on the left and right sides of the device housing 1. This ensures that the inverted "U" shaped filter plate 12 can filter the liquid, and the liquid falling into the collection box 13 can also be filtered by the filter plate 12.
[0040] like Figure 2 As shown, in a preferred embodiment, based on the above method, the other end of the spring 21 is further fixedly connected to a limiting plate 22, a clamping plate 23 is fixedly connected to the limiting plate 22, and a pull rod 24 is fixedly connected to the limiting plate 22. The height of the bottom end of the feeding tube 16 is greater than the height of the bottom end inside the device housing 1, which can ensure that the feeding tube 16 can fall smoothly into the bottom of the device housing 1 when feeding.
[0041] Specifically, when using this rock mass fracture seepage simulation experimental device: (in conjunction with...) Figure 1-5 When it is necessary to disassemble the fixing frame 2 to replace it with a fixing frame 2 of different sizes, the pull rod 24 on the two mounting boxes 20 can be pulled. The pull rod 24 drives the limiting plate 22 to move. The limiting plate 22 can squeeze the spring 21. At the same time, the limiting plate 22 can remove the clamping plate 23 from the fixing frame 2. After the fixing frame 2 is no longer obstructed, it can be taken out for disassembly and replacement. When fixing the replacement fixing frame 2, the pull rod 24 is released. Under the push of the spring 21, the limiting plate 22 and the clamping plate 23 are reset. The clamping plate 23 is engaged in the fixing frame 2, which can limit and fix it, making it convenient to fix fixing frames 2 with different hole sizes.
[0042] The collected rock sample 5 is inserted into the fixing frame 2 and limited by the support plate 3. With the help of the sealing gasket 4, it can achieve a sealing and protective effect. Water is added into the outer shell 1 of the device. The added water can seep through the cracks of the rock sample 5 through the fixing frame 2. The seeping liquid can filter the impurities in the liquid through the filter plate 12 to avoid the impurities affecting the output detection effect. To prevent the material from clogging the filter plate 12, the motor 6 can be turned on to drive the reciprocating screw 7 to rotate. The reciprocating screw 7 can drive the moving block 8 to move back and forth. When the moving block 8 drives the scraper 9 to move, the scraper 9 can move smoothly by the sliding support of the slider 10 on the slide rod 11. The scraper 9 can scrape off the filtered impurities and clean them into the collection box 13 to prevent the impurities from clogging and affecting the filtration effect.
[0043] The seeping liquid can be guided by the guide plate 15 and discharged through the discharge pipe 16. During discharge, the flow rate sensor 17 on the discharge pipe 16 can detect the flow. The detected data can be recorded and viewed through the control panel 18. When the liquid needs to be cleaned later, the discharge pipe 19 can be opened to discharge and collect the liquid. When it is necessary to clean the impurities collected in the collection box 13, the sealing plate 14 on the collection box 13 can be removed to clean and collect the impurities. The signal of the flow rate sensor 17 used is (FTB-930-I).
[0044] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, as well as all technical solutions and improvements that do not depart from the spirit and scope of practicality, are covered within the scope of the claims of the present utility model.
