Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a foundation testing device for water conservancy projects. Background Technology

[0002] The foundation testing device for water conservancy projects is designed for precise detection of the condition of water conservancy foundations. It adopts a high-strength alloy drill rod and is equipped with a special drill bit to adapt to complex soil conditions and has high drilling efficiency. It is equipped with a powerful drive system that can output stable power to meet the needs of deep drilling. It has an intelligent speed control and depth monitoring module to accurately control the drilling speed and record the depth, ensuring the accuracy of sampling and helping to ensure the safe construction of water conservancy projects.

[0003] Existing technologies, such as the utility model with publication number CN214143626U, relate to the field of foundation testing, specifically a foundation testing device for water conservancy projects. It includes a mounting plate with several support rods welded to both ends of its lower surface. Each support rod has a roller with a braking structure mounted on one end. Telescopic cylinders are welded to the middle of both ends of the lower surface of the mounting plate. A base is welded to the piston rod at one end of each telescopic cylinder, and an insertion rod is welded below each base. A through hole is opened in the middle of the upper surface of the mounting plate, and fixing blocks are welded to both ends of the through hole. A slider is welded to one end of each fixing block, and a fixing rod is slidably mounted between two sliders. A mounting block is welded to the lower end of the fixing rod. A first slot is opened on the lower surface of the mounting block, and a first locking block is engaged in the first slot. A connecting block is welded to one end of the first locking block, and a probe is mounted on one end of the connecting block. This utility model makes foundation testing more accurate.

[0004] However, with existing sampling devices, if soil samples are not quickly and properly sealed after extraction, the moisture will evaporate and be lost rapidly, causing the soil samples to dry, crack, and shrink. This will result in serious deviations in the results of some testing items that rely on moisture content to determine soil properties, such as the determination of the liquid and plastic limits of cohesive soils. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing sampling devices. If soil samples are not quickly and properly sealed after extraction, moisture evaporates rapidly, causing the soil samples to dry, crack, and shrink. This leads to serious deviations in the results of some testing items that rely on moisture content to determine soil properties, such as the determination of the liquid and plastic limits of cohesive soil. Therefore, this invention proposes a foundation testing device for water conservancy projects.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a foundation testing device for water conservancy projects, comprising a base plate and a sampling device. An assembly frame is fixedly connected to the upper surface of the base plate, a servo motor is fixedly connected to the upper surface of the assembly frame, a pneumatic rod is fixedly connected to the drive end of the servo motor, a drilling rod is fixedly connected to the lower surface of the pneumatic rod, and a wheel is rotatably connected to the lower surface of the base plate. The sampling device is disposed on the surface of the base plate and includes a cylinder fixedly connected to the base plate. A support is fixedly connected to the upper surface of the cylinder, and the upper surface of the support... A protective ring is fixedly connected to the surface, and soft bristles are fixedly connected to the inner side of the protective ring. A pusher block is slidably connected to the inner wall of the cylinder. A through hole is opened on the side of the bottom plate near the cylinder. By setting up a sampling device, when the drilling rod drills into the ground and then resets, the soft bristles scrape off the adhering soil in time, so that the sample collection is more complete, reducing soil loss and preserving the original stratum information of the sample to the greatest extent. This provides reliable material for the accurate analysis of the soil characteristics of the foundation of water conservancy projects, and facilitates the rapid and proper sealing of the collected samples to prevent the samples from being disturbed by the external environment, maintain the stability of the sample state, and meet the needs of subsequent long-term and high-precision testing.

[0007] Preferably, a guide tube is fixedly connected to the side of the cylinder near the through hole, and the position of the guide tube corresponds to the through hole. By setting up the cylinder, when the drill rod, carrying underground soil, drills out of the ground and moves upward, the soft bristles scrape off the soil adhering to the surface of the drill rod, and this soil then falls into the cylinder. The cylinder acts as a temporary storage space, preventing soil from scattering everywhere, ensuring the orderly collection of samples, avoiding soil loss, and allowing for the collection of as complete a stratigraphic sample as possible in the future.

[0008] Preferably, the soft bristles contact the drilling rod, and the cylinder has a hole in the center. By setting the soft bristles, after the drilling operation is completed, the drilling rod emerges from the ground, and a large amount of soil adheres to its surface. The soft bristles rub against the upward-moving drilling rod. Utilizing the fine and soft characteristics of the soft bristles, they can gently and effectively scrape the drilling rod, peel off the attached soil, and prevent the soil from being carried out with the drilling rod and scattered everywhere, maintaining the cleanliness of the work area and preparing for subsequent sample collection.

[0009] Preferably, the drilling rod is inserted into a hole on the surface of the cylinder, and there are two brackets arranged in a mirror-symmetrical manner.

[0010] Preferably, there are multiple soft bristles, and the multiple soft bristles are arranged in a circumferential array.

[0011] Preferably, a collection assembly is provided on the lower surface of the base plate. The collection assembly includes a box body corresponding to the through hole. Insert rods are slidably connected to both sides of the box body. By setting up the collection assembly, the collection assembly is equipped with a box body that is easy to disassemble. The box body is fixed by a simple connection between the insert rods and the buckle. After the operation is completed, the box body can be removed by pulling the insert rods to disengage from the buckle. This design is convenient and quick, and allows the box body to be quickly separated from the device, providing an independent and closed storage space for the sample, reducing external environmental interference, maintaining the original characteristics of the sample, and facilitating subsequent experimental detection.

[0012] Preferably, a buckle is fixedly connected to the side of the base plate near the insertion rod. The insertion rod is inserted into the buckle. By setting the insertion rod, the box body is connected to the main body of the device, so that the box body is stably fixed in the corresponding position during the collection of soil samples, and it is precisely aligned with the guide tube and through hole. In this way, the scraped soil can smoothly enter the box body through the guide tube and through hole, ensuring a stable and smooth collection process, and avoiding the box body shaking or shifting, which would affect the sample collection efficiency and integrity.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up a sampling device and a collection component, when in use, the servo motor is started, and the servo motor rotates while driving the pneumatic rod to rotate. The pneumatic rod starts and squeezes the drilling rod downward. At the same time, the drilling rod follows the rotation of the pneumatic rod and drills into the ground. When the drilling rod enters the predetermined depth, the pneumatic rod, in conjunction with the servo motor, drives the drilling rod to reset. When the drilling rod moves upward, it rubs against the soft bristles, which scrape off the soil adhering to the surface of the drilling rod and drop it into the cylinder. Pushing the push block facilitates the soil to enter the through hole through the guide tube and fall into the box. Pulling the insertion rod to disengage from the buckle allows the box to be removed for easy sample preservation.

[0015] By designing this utility model, when the drilling rod drills into the ground and then resets, the soft bristles promptly scrape off the adhering soil, making the sample collection more complete, reducing soil loss and preserving the original stratum information of the sample to the greatest extent. This provides reliable material for the accurate analysis of the soil characteristics of the foundation of water conservancy projects, facilitates the rapid and proper sealing of the collected samples, prevents the samples from being disturbed by the external environment, maintains the stability of the sample state, and meets the needs of subsequent long-term, high-precision testing.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a foundation testing device for water conservancy projects, including a base plate 1 and a sampling device 7.

[0023] In this implementation scheme: the sampling device 7 includes a cylinder 74, which is fixedly connected to the base plate 1. A bracket 73 is fixedly connected to the upper surface of the cylinder 74, and a protective ring 71 is fixedly connected to the upper surface of the bracket 73. Soft bristles 72 are fixedly connected to the inner side of the protective ring 71. A pusher block 75 is slidably connected to the inner wall of the cylinder 74. A through hole 77 is opened on the side of the base plate 1 near the cylinder 74. By setting up the sampling device 7, when the drilling rod 5 drills into the ground and then resets, the soft bristles 72 promptly scrape off the adhering soil, making the sample collection more complete, reducing soil loss, and preserving the original stratum information of the sample to the greatest extent. This provides reliable material for the accurate analysis of the soil characteristics of the foundation of water conservancy projects, facilitates the rapid and proper sealing of the collected samples, prevents the samples from being disturbed by the external environment, maintains the stability of the sample state, and meets the needs of subsequent long-term and high-precision testing.

[0024] Specifically, a guide tube 76 is fixedly connected to the side of the cylinder 74 near the through hole 77. The position of the guide tube 76 corresponds to the through hole 77. By setting up the cylinder 74, when the drill rod 5, carrying underground soil, drills out of the ground and moves upward, the soft bristles 72 scrape off the soil adhering to the surface of the drill rod 5, and this soil then falls into the cylinder 74. The cylinder 74 acts as a temporary storage space to prevent soil from scattering, ensure the orderly collection of samples, avoid soil loss, and allow for the collection of as complete a stratigraphic sample as possible in the future.

[0025] Specifically, the soft bristles 72 contact the drilling rod 5, and a hole is opened in the center of the cylinder 74. By setting the soft bristles 72, after the drilling operation is completed, the drilling rod 5 emerges from the ground, and a large amount of soil will adhere to its surface. The soft bristles 72 rub against the upward-moving drilling rod 5. Utilizing the fine and soft characteristics of the soft bristles 72, the drilling rod 5 can be gently and effectively scraped to remove the attached soil, preventing the soil from being carried out with the drilling rod 5 and scattered everywhere, maintaining the cleanliness of the work area, and also preparing for subsequent sample collection.

[0026] Specifically, the drilling rod 5 is inserted into the hole on the surface of the cylinder 74, and there are two brackets 73, which are arranged in a mirror symmetrical manner.

[0027] Specifically, there are multiple soft bristles 72, which are arranged in a circular array.

[0028] Specifically, a collection component 8 is provided on the lower surface of the base plate 1. The collection component 8 includes a box body 81, which corresponds to the through hole 77. Insert rods 82 are slidably connected to both sides of the box body 81.

[0029] In this embodiment: By setting up a collection component 8, the collection component 8 is equipped with a box 81 that is easy to disassemble. The box 81 is fixed by a simple connection between the insert rod 82 and the buckle 83. After the operation is completed, the box 81 can be removed by pulling the insert rod 82 to disengage from the buckle 83. This design is convenient and quick, and allows the box 81 to be quickly separated from the device, providing an independent and closed storage space for the sample, reducing external environmental interference, maintaining the original characteristics of the sample, and facilitating subsequent experimental detection.

[0030] Specifically, a retaining ring 83 is fixedly connected to the side of the base plate 1 near the insert rod 82, and the insert rod 82 and the retaining ring 83 are inserted into each other.

[0031] In this embodiment: by setting up the insertion rod 82, the insertion rod 82 connects the box body 81 to the main body of the device, so that the box body 81 is stably fixed in the corresponding position during the collection of soil samples, so that it is precisely connected with the guide tube 76 and the through hole 77. In this way, the scraped soil can smoothly enter the box body 81 through the guide tube 76 and the through hole 77, ensuring a stable and smooth collection process, and avoiding the shaking or displacement of the box body 81, which would affect the sample collection efficiency and integrity.

[0032] Working principle: By setting up the sampling device 7 and the collection component 8, when in use, the servo motor 3 is started. The rotation of the servo motor 3 drives the pneumatic rod 4 to rotate. The pneumatic rod 4 starts and squeezes the drilling rod 5 downward. At the same time, the drilling rod 5 follows the rotation of the pneumatic rod 4 and drills into the ground. When the drilling rod 5 reaches the predetermined depth, the pneumatic rod 4, in conjunction with the servo motor 3, drives the drilling rod 5 to return to its original position. When the drilling rod 5 moves upward, it rubs against the soft bristles 72. The soft bristles 72 scrape off the soil adhering to the surface of the drilling rod 5 and drop it into the cylinder 74, pushing the pusher block 75, which facilitates the movement of the soil through the guide tube 76. The sample enters the through hole 77 and falls into the box 81. Pulling the insertion rod 82 to disengage from the buckle 83 allows the box 81 to be removed for easy sample preservation. By designing this utility model, when the drilling rod 5 drills into the ground and then resets, the soft bristles 72 promptly scrape off the adhering soil, making the sample collection more complete, reducing soil loss and preserving the original stratum information of the sample to the greatest extent. This provides reliable material for the accurate analysis of the soil characteristics of the foundation of water conservancy projects, and facilitates the rapid and proper sealing of the collected samples to prevent the samples from being disturbed by the external environment, maintain the stability of the sample state, and meet the needs of subsequent long-term and high-precision testing.
