Description

Technical Field

[0001] This utility model belongs to the field of engineering foundation testing technology, specifically a water conservancy engineering foundation testing device. Background Technology

[0002] Foundation testing for water conservancy projects is a crucial step in ensuring the safety, stability, and long-term operation of these projects. By conducting comprehensive and systematic testing of the foundation, we can fully understand its physical properties, mechanical characteristics, and potential engineering risks, providing an important basis for project design, construction, and operation. The bearing capacity, shear strength, and peak torque of the foundation are important indicators for evaluating its stability and safety. Testing these indicators can help identify potential risks in a timely manner and ensure the structural safety of buildings.

[0003] A patent with publication number CN114855742B discloses a foundation testing device for water conservancy projects. This device, by setting up three adjustment and control units and three testing devices, can simultaneously perform three-point testing during use, making the test results more accurate. Through the first and second sliding adjustment devices, the three adjustment and control units and the testing devices can be controlled to slide and move closer on the first and second track rings respectively. After the three testing devices are close together, they can perform single-point testing on a concentrated area. At this time, the pressure of the counterweights in the three adjustment and control units can be applied to this testing point, so that the device can apply different testing pressures to detect the settlement according to different construction sites. The above-mentioned scheme still has some problems in practical application. Usually, when sampling and testing the foundation soil, only a drill bit can be used to drill into the foundation and collect the soil that the drill bit drilled out for testing. However, when testing the bearing capacity of the foundation, it is necessary to use a bearing capacity testing device to conduct impact testing on the foundation. This is not only cumbersome to operate, but also because the existing testing devices have too limited functions. As a result, multiple devices are needed to cooperate to complete the testing work, which greatly reduces the efficiency of foundation testing.

[0004] Therefore, this utility model provides a foundation testing device for water conservancy projects. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The water conservancy engineering foundation detection device of this utility model includes a vehicle body and a chain-type moving component set at the lower end of the vehicle body. A fixed frame is installed on one side of the upper end of the vehicle body. A U-shaped rotating frame is rotatably connected to one side of the fixed frame. A frame is installed in the inner cavity of the U-shaped rotating frame. A counterweight is slidably connected to the inner cavity of the frame. Limiting grooves are opened on both sides of the lower end of the frame. A fixed column is fixedly connected to the inner cavity of the limiting groove. A limiting slide plate is slidably connected to the outside of the fixed column. A sampling rod is fixedly connected to the lower end of the limiting slide plate. A storage groove is opened at the lower end of the sampling rod. A T-shaped slide rod is slidably connected to the inner cavity of the storage groove. A second spring is fixedly connected to the bottom of the inner cavity of the storage groove, and one end of the second spring is fixedly connected to the T-shaped slide rod. A groove is opened inside the outside of the T-shaped slide rod, and a third spring is set in the inner cavity of the groove. A stop block is slidably connected to the inner cavity of the groove.

[0007] Preferably, the inner wall of the frame has an installation groove, and multiple electromagnetic blocks are installed in the inner cavity of the installation groove. Magnets are installed on both sides of the counterweight, and the magnets are slidably connected to the inner cavity of the frame.

[0008] Preferably, a rubber pad is provided at the lower end of the counterweight to reduce the impact force on the limiting slide plate, and a support rod is installed on one side of the fixing frame, with one end of the support rod fixedly installed to the vehicle body.

[0009] Preferably, a power distribution box is installed on the upper end of the frame, and the power distribution box is electrically connected to the electromagnetic block through wires, and controls the power-on and power-off sequence of the electromagnetic block.

[0010] Preferably, a first spring is fixedly connected to the bottom of the inner cavity of the limiting groove, and one end of the first spring is fixedly connected to the limiting slide plate. An iron block is provided inside the lower end of the frame to increase the downward weight of the frame.

[0011] Preferably, a detection block is slidably connected to the lower end of the sampling rod, and an elastic element is fixedly connected to the upper end of the detection block, with one end of the elastic element fixedly connected to the lower end of the frame.

[0012] Preferably, a counterweight assembly is installed on one side of the upper end of the vehicle body, and the counterweight assembly includes a box installed on one side of the upper end of the vehicle body, a support column is fixedly connected to the bottom of the inner cavity of the box, multiple counterweight plates are installed on the outside of the support column, and a baffle is installed on the upper end of the box.

[0013] The beneficial effects of this utility model are as follows: 1. The water conservancy engineering foundation testing device of this utility model supplies power to the electromagnetic blocks sequentially from bottom to top through a power distribution box. After the electromagnetic blocks are energized, they form an N pole that attracts the S pole magnet and moves upward. At the same time, the electromagnetic blocks are de-energized sequentially from bottom to top to prevent two electromagnetic blocks from being simultaneously energized and attracting the magnet, which would affect the efficiency of the magnet driving the counterweight block upward. This allows multiple electromagnetic blocks to attract the magnet alternately and move upward, so that the magnet drives the counterweight block to the top of the frame. Then, the power distribution box de-energizes the electromagnetic blocks at the top of the frame cavity, allowing the counterweight block to slide rapidly downward in the frame cavity using its own weight. The counterweight block impacts the limiting slide plate with the rubber pad, and the limiting slide plate pushes the sampling rod into the foundation, realizing soil sampling and testing of foundations with hard soil. This improves the automation level of the testing device and the efficiency of foundation soil sampling.

[0014] 2. The foundation testing device for water conservancy projects described in this utility model, while sampling and testing the foundation, simultaneously moves the counterweight block to the top of the frame cavity. Power is then supplied from top to bottom via a distribution box, causing the electromagnetic block to form an S-pole that repels the S-pole magnet. Simultaneously, the electromagnetic block is de-energized and demagnetized sequentially from top to bottom to avoid wasting electrical energy. This creates an electromagnetic guide rail within the frame cavity that accelerates the magnet. The S-pole electromagnetic block 14, in conjunction with the S-pole magnet, accelerates the counterweight block, causing it to move rapidly downwards and impact the limiting slide plate. This, in turn, causes the limiting slide plate to... The sampling rod is pushed into the foundation to take a sample. At the same time, the sampling rod drives the detection block to come into contact with the foundation. The detection block compresses the elastic element, and an impact force detection probe is set at the lower end of the detection block. The impact force detection probe is then used to detect the bearing capacity of the foundation and collect and store the detection data. When it is necessary to test different soil foundations, the number of electromagnetic blocks energized is increased. The electromagnetic blocks use the principle of repulsion between the S poles to accelerate the magnet by a factor of two, thereby increasing the speed at which the magnet drives the counterweight block to move downward, and thus increasing the impact force of the counterweight block, so as to realize the function of testing the bearing capacity of different soil foundations.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example 1, as Figures 1 to 6 As shown in the embodiment of this utility model, the water conservancy engineering foundation testing device includes a vehicle body 1 and a chain-type moving assembly 2 set at the lower end of the vehicle body 1. A fixed frame 5 is installed on one side of the upper end of the vehicle body 1. A U-shaped rotating frame 6 is rotatably connected to one side of the fixed frame 5. A frame 7 is installed in the inner cavity of the U-shaped rotating frame 6. A counterweight 9 is slidably connected to the inner cavity of the frame 7. Limiting grooves 20 are opened on both sides of the lower end of the frame 7. A fixed column 11 is fixedly connected to the inner cavity of the limiting groove 20. A limiting slide plate 10 is slidably connected to the outside of the fixed column 11. A sampling rod 13 is fixedly connected to the lower end of the limiting slide plate 10. A storage groove 19 is opened at the lower end of the sampling rod 13. A T-shaped slide rod 17 is slidably connected to the inner cavity of the storage groove 19. A second spring 18 is fixedly connected to the bottom of the inner cavity of the storage groove 19, and one end of the second spring 18 is fixedly connected to the T-shaped slide rod 17. A groove is opened on the outside of the T-shaped slide rod 17, and a third spring 25 is set in the inner cavity of the groove. A stop block 24 is slidably connected to the inner cavity of the groove.

[0019] Specifically, during the inspection of the water conservancy project site, the vehicle body 1 is moved remotely, causing the fixed frame 5 to move synchronously. The vehicle body 1 uses a chain-type moving component 2 for power movement, which avoids the situation where conventional moving vehicles easily get stuck in the mud when the water conservancy project foundation soil is wet. After the vehicle body 1 moves the fixed frame 5 to the inspection position, the counterweight 9 is driven to fall from the top of the inner cavity of the frame 7, causing the counterweight 9 to slide in the inner cavity of the frame 7 and impact the limiting slide plate 10. The limiting slide plate 10 then pushes the sampling rod 13 downward, causing the sampling rod 13 to impact the water conservancy project site and insert into the site. At the same time, the soil of the site compresses the T-shaped sliding rod 17. The device moves upward, causing the T-shaped slide bar 17 to press the second spring 18 into the inner cavity of the storage groove 19. At the same time, the third spring 25 in the inner cavity of the groove bounces up the abutment block 24, causing the abutment block 24 to abut against the inner cavity of the storage groove 19. This causes the sampling rod 13 to press the foundation into the soil pile in the inner cavity of the storage groove 19 for collection and storage. Then, the vehicle body is driven to move again to sample the next area. This solves the problem that existing water conservancy engineering foundation testing devices usually require operators to manually enter the water conservancy engineering foundation to sample, and after each sampling, the sampled soil needs to be collected before sampling the next area. This is not only cumbersome but also affects the efficiency of sampling and testing.

[0020] like Figure 1 and Figure 3 As shown, the inner wall of the frame 7 has an installation groove 21, and multiple electromagnetic blocks 14 are installed in the inner cavity of the installation groove 21. Magnets 15 are installed on both sides of the counterweight 9, and the magnets 15 are slidably connected to the inner cavity of the frame 7.

[0021] like Figure 1 and Figure 3 As shown, a rubber pad 16 is provided at the lower end of the counterweight 9 to reduce the impact force on the limiting slide plate 10. A support rod 4 is installed on one side of the fixing frame 5, and one end of the support rod 4 is fixedly installed to the vehicle body 1.

[0022] like Figure 1 and Figure 3 As shown, a power distribution box 8 is installed on the upper end of the frame 7, and the power distribution box 8 is electrically connected to the electromagnetic block 14 through wires, and controls the power-on and power-off sequence of the electromagnetic block 14.

[0023] Specifically, during foundation testing, the electromagnetic blocks 14 are energized via the distribution box 8, sequentially supplying power from bottom to top. This causes the N-pole of each electromagnetic block 14 to attract the S-pole magnet 15, which then moves upwards. Simultaneously, the electromagnetic blocks 14 are de-energized sequentially from bottom to top to prevent two blocks from being simultaneously energized and attracting the magnet 15, thus affecting the efficiency of the magnet 15 in moving the counterweight 9 upwards. This allows multiple electromagnetic blocks 14 to alternately attract the magnet 15, causing it to move upwards and thus the magnet 15 to move the counterweight 9 upwards. Once the counterweight 9 reaches the top of the frame 7, the distribution box 8 de-energizes the electromagnetic blocks 14 at the top of the frame 7's inner cavity, allowing the counterweight 9 to slide rapidly downwards within the frame 7 using its own weight. The counterweight 9 then impacts the limiting slide plate 10 using the rubber pad 16, causing the limiting slide plate 10 to push the sampling rod 13 into the foundation for sampling. Meanwhile, regarding the... When sampling hard soil foundations, the counterweight 9 is moved to the top of the inner cavity of the frame 7, and then the power distribution box 8 supplies power from top to bottom, causing the electromagnetic block 14 to form the S pole. At the same time, the electromagnetic block 14 is de-energized and demagnetized from top to bottom, thus forming an electromagnetic guide rail in the inner cavity of the frame 7. Simultaneously, the electromagnetic block 14 with the S pole, in conjunction with the magnet 15 with the S pole, accelerates the counterweight 9, causing it to move rapidly downwards and impact the limiting slide plate 10. This causes the limiting slide plate 10 to push the sampling rod 13 into the foundation for sampling. This method enables soil sampling and testing of hard soil foundations, solving the problem that existing water conservancy engineering foundation testing devices typically use a threaded drill bit to rotate the foundation and then sample the soil. This is not only cumbersome to operate, but also requires significant pressure to press the drill bit into the foundation for sampling in hard soil conditions.

[0024] Example 2, as Figures 3 to 5 As shown, a first spring 12 is fixedly connected to the bottom of the inner cavity of the limiting groove 20, and one end of the first spring 12 is fixedly connected to the limiting slide plate 10. An iron block is provided inside the lower end of the frame 7 to increase the downward weight of the frame 7.

[0025] like Figures 3 to 5 As shown, a detection block 22 is slidably connected to the lower end of the sampling rod 13, and an elastic element 23 is fixedly connected to the upper end of the detection block 22, with one end of the elastic element 23 fixedly connected to the lower end of the frame 7.

[0026] Specifically, after the vehicle body 1 moves onto the foundation, if the ground is uneven, the frame 7 will use the internal iron block to move vertically downwards. At the same time, the frame 7 will drive the U-shaped rotating frame 6 to rotate, so that the frame 7 always remains perpendicular to the ground, thereby improving the accuracy of foundation detection.

[0027] like Figure 1 , Figure 2 and Figure 6 As shown, a counterweight assembly 3 is installed on one side of the upper end of the vehicle body 1, and the counterweight assembly 3 includes a box 31 installed on one side of the upper end of the vehicle body 1. A support column 32 is fixed to the bottom of the inner cavity of the box 31, and multiple counterweight plates 33 are installed on the outside of the support column 32. A baffle 34 is installed on the upper end of the box 31.

[0028] Specifically, during foundation testing, after the counterweight 9 is moved to the top of the inner cavity of the frame 7, power is supplied from top to bottom via the distribution box 8. This causes the electromagnetic block 14 to form an S pole that repels the S pole magnet 15. Simultaneously, the electromagnetic block 14 is de-energized and demagnetized sequentially from top to bottom to avoid wasting electrical energy. This creates an electromagnetic rail within the inner cavity of the frame 7 to accelerate the magnet 15. The S pole electromagnetic block 14, in conjunction with the S pole magnet 15, accelerates the counterweight 9, causing it to move rapidly downwards and impact the limiting slide plate 10. This causes the limiting slide plate 10 to push the sampling rod 13 into the foundation for sampling. Simultaneously, the sampling rod 13 causes the detection block 22 to contact the foundation, compressing the elastic element 23. An impact force detection probe is located at the lower end of the detection block 22, which is then used to detect the impact force on the foundation. The device measures the bearing capacity of the foundation and collects and stores the test data. When testing is required for different soil foundations, the number of electromagnetic blocks 14 energized is increased, allowing the electromagnetic blocks 14 to accelerate the magnet 15 multiple times using the principle of repulsion between their S poles. This increases the speed at which the magnet 15 drives the counterweight 9 downward, thereby increasing the impact force of the counterweight 9. This enables the device to test the bearing capacity of different soil foundations, thus solving the problem that existing water conservancy engineering foundation testing devices cannot simultaneously test the bearing capacity of the foundation when sampling and testing the foundation soil. This results in a single function of the testing device, where the bearing capacity can only be tested using the foundation bearing capacity testing device alone. Moreover, it is difficult to adjust and increase the impact force of the testing blocks according to different soil types, making it difficult to accurately detect the bearing capacity of the foundation.

[0029] Working principle: During foundation testing, the electromagnetic blocks 14 are energized via the distribution box 8, sequentially supplying power from bottom to top. This causes the N pole of each electromagnetic block 14 to attract the S pole of the magnet 15, moving it upwards. Simultaneously, the electromagnetic blocks 14 are de-energized sequentially from bottom to top to prevent two blocks from being simultaneously energized and attracting the magnet 15, which would affect the efficiency of the magnet 15 in moving the counterweight 9 upwards. This allows multiple electromagnetic blocks 14 to alternately attract the magnet 15, moving it upwards, thus enabling the magnet 15 to move the counterweight 9 upwards. Once the counterweight 9 reaches the top of the frame 7, the distribution box 8 de-energizes the electromagnetic blocks 14 at the top of the frame 7's inner cavity, allowing the counterweight 9 to slide rapidly within the frame 7 using its own weight. The counterweight 9 moves downward and impacts the limiting slide plate 10 using the rubber pad 16, causing the limiting slide plate 10 to push the sampling rod 13 into the foundation for sampling. When sampling on foundations with harder soil, the counterweight 9 is transported to the top of the inner cavity of the frame 7, and then the power distribution box 8 supplies power from top to bottom, causing the electromagnetic block 14 to form the S pole. At the same time, the electromagnetic block 14 is de-energized and demagnetized from top to bottom, thereby forming an electromagnetic guide rail in the inner cavity of the frame 7. Simultaneously, the electromagnetic block 14 with the S pole, in conjunction with the magnet 15 with the S pole, accelerates the counterweight 9, causing it to move downward rapidly and impact the limiting slide plate 10. This causes the limiting slide plate 10 to push the sampling rod 13 into the foundation for sampling, thus enabling soil sampling and testing on foundations with harder soil. During foundation testing, after the counterweight 9 is moved to the top of the inner cavity of the frame 7, power is supplied from top to bottom via the distribution box 8. This causes the electromagnetic block 14 to form an S pole that repels the S pole magnet 15. Simultaneously, the electromagnetic block 14 is de-energized and demagnetized sequentially from top to bottom to avoid wasting electrical energy. This creates an electromagnetic rail within the inner cavity of the frame 7 that accelerates the magnet 15. The S pole electromagnetic block 14, in conjunction with the S pole magnet 15, accelerates the counterweight 9, causing it to move rapidly downwards and impact the limiting slide plate 10. The limiting slide plate 10 then pushes the sampling rod 13 into the foundation. Sampling is performed inside the foundation, and the sampling rod 13 drives the detection block 22 to contact the foundation. The detection block 22 compresses the elastic element 23. An impact force detection probe is installed in the lower end of the detection block 22. The impact force detection probe is used to detect the bearing capacity of the foundation and collect and store the detection data. When it is necessary to test different soil foundations, the number of electromagnetic blocks 14 energized is increased, so that the electromagnetic blocks 14 use the principle of repulsion between the S poles to accelerate the magnet 15 by a factor of two, thereby increasing the speed at which the magnet 15 drives the counterweight block 9 to move downward, thereby increasing the impact force of the counterweight block 9, and realizing the function of testing the bearing capacity of different soil foundations.
