Description

Technical Field

[0001] This utility model relates to the field of engineering quality testing equipment technology, and in particular to an on-site testing device for the porosity of ecological grid. Background Technology

[0002] Ecological gabions, as an important flexible support structure, are widely used in slope protection, river management, and ecological restoration in water conservancy, transportation, and municipal engineering projects. The stability and functionality of ecological gabions largely depend on the density of the stones filling them, and the porosity is a key technical indicator for measuring this density, directly affecting the overall quality and safety of the project.

[0003] Therefore, accurate detection of the porosity of the ecological grid is an essential step during construction and final acceptance. Currently, the industry commonly uses a detection principle based on Archimedes' principle, which calculates the volume of the stone by measuring its weight in air and its apparent weight in water, thus determining the porosity. While the principle is clear, this method faces a key technical challenge in field application.

[0004] When a cage filled with stones is submerged in water for apparent weight measurement, numerous tiny air bubbles adhere to the surface of the stones and in the gaps between them due to the rough, uneven surface and dense packing of the stones. These air bubbles, unable to escape naturally, generate additional buoyancy, causing the apparent weight measured by the electronic scale to be lower than expected. This deviation in apparent weight measurement directly leads to an overestimation of the calculated stone volume, ultimately resulting in an underestimation of the calculated porosity, which differs significantly from the actual situation. This measurement inaccuracy caused by air bubble interference seriously affects the objective evaluation of project quality. Existing on-site testing methods often lack effective and reliable defoaming mechanisms, making it difficult to guarantee the accuracy of the test results.

[0005] Therefore, this utility model proposes an on-site detection device for the porosity of ecological grid to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an on-site detection device for the porosity of ecological grid, which aims to improve the problem of inaccurate measurement results caused by the difficulty in removing air bubbles attached to the surface of the stone in the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an ecological grid porosity on-site detection device, comprising a forklift, a water tank body, an electronic scale, and a mesh box, wherein the water tank body is fixed on the forklift, the electronic scale is suspended at the end of the forklift lifting mechanism, and the mesh box can be connected below the electronic scale; the device also includes a defoaming component and an adjustment component; The defoaming assembly includes a fixing rod and a nozzle, with the nozzle fixedly mounted on the fixing rod. Furthermore, the adjustment assembly is fixed above the inner wall of the water tank body. The adjustment assembly includes an electric push rod, a push plate, a guide column, a first fixing block, a connecting plate, and a second fixing block. The push plate is fixedly connected to the output end of the electric push rod, the guide column allows the push plate to slide, and the first fixing block is fixedly connected to the push plate. The first fixing block is rotatably connected to one end of the connecting plate, and the other end of the connecting plate is rotatably connected to the second fixing block. The second fixing block is sleeved and fixed on the fixing rod, and is used to drive the fixing rod and the nozzle to rotate under the drive of the electric push rod, through the linkage of the push plate, the first fixing block, and the connecting plate. Preferably, the defoaming assembly further includes a water storage tank and a water pump, the water storage tank and the water pump being installed on the forklift, and the water pump being connected to the nozzle via an outlet pipe and a connecting pipe; Preferably, the connecting pipe is a flexible hose, one end of which is connected to the outlet of the water pump, and the other end is connected to the inlet of the fixing rod. Preferably, both the electric push rod and the guide column are fixedly installed on the bracket above the water tank body; Preferably, the forklift is equipped with wheels that can move on tracks at the bottom; Preferably, one end of the outlet pipe is connected to the bottom of the water storage tank, and the other end is connected to the inlet of the water pump; Preferably, the lifting mechanism of the forklift is used to drive the electronic scale and the wire mesh box to move vertically, so as to place the wire mesh box into or remove it from the water tank body; Preferably, there are two guide posts, which are arranged in parallel, and the two ends of the push plate are slidably sleeved on the two guide posts respectively.

[0008] This utility model has the following beneficial effects: 1. This utility model solves the problems of existing technologies, such as reliance on laboratory equipment for porosity detection, inability to conduct rapid on-site testing, cumbersome procedures, and low efficiency, by integrating the water tank body, electronic scale, defoaming component, and adjustment component onto a mobile forklift. It achieves the effects of device integration, easy mobility, on-site testing anytime and anywhere, and significantly improved work efficiency.

[0009] 2. This utility model, by setting up a defoaming component, uses a water pump to drive water flow through a nozzle to actively flush the stones submerged in water. This solves the problem in the prior art that when measuring weight in water, the buoyancy interference caused by air bubbles attached to the surface and gaps of the stones leads to inaccurate measurement data and large errors in the final calculation results. It achieves the effect of effectively removing interfering air bubbles, ensuring the authenticity and reliability of the weighing data in water, and significantly improving the accuracy of porosity calculation.

[0010] 3. This utility model, by setting an adjustment component and using an electric push rod to drive the linkage mechanism, thereby driving the fixed rod with the nozzle installed to rotate, solves the problems of irregular stone accumulation, dead angles in fixed-angle spraying, and difficulty in removing some stubborn air bubbles. It achieves the effect of multi-angle, dead-angle-free rinsing of stones and ensures that air bubbles are completely removed, further guaranteeing the accuracy of the test results.

Detailed Implementation

[0013] 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.

[0014] Reference Figures 1-4This utility model provides an embodiment of an ecological grid porosity on-site testing device, comprising a forklift 1 and a water tank body 7 fixed on the forklift 1. The forklift 1 serves as the moving and carrying platform for the entire device, and the water tank body 7 is used to contain liquid to immerse the material to be tested. The bottom of the forklift 1 is equipped with wheels that can move on a track 4 to achieve precise displacement of the device. A lifting mechanism is provided on the forklift 1, and an electronic scale 5 is suspended at the end of the lifting mechanism of the forklift 1. A mesh box 6 is detachably connected below the electronic scale 5 and is used to contain the stone material to be tested. To achieve accurate measurement, a defoaming component 2 and an adjusting component 3 for controlling the defoaming component 2 are also included inside the water tank body 7. The adjustment assembly 3 is fixed above the inner wall of the water tank body 7. The adjustment assembly 3 includes an electric push rod 301, a push plate 302, a guide column 303, a first fixing block 304, a connecting plate 305, and a second fixing block 306. The push plate 302 is fixedly connected to the output end of the electric push rod 301. The guide column 303 is slidably set for the push plate 302 to guide the movement of the push plate 302. The first fixing block 304 is fixedly connected to the push plate 302, so that the first fixing block 304 moves linearly synchronously with the push plate 302. One end of the connecting plate 305 is rotatably connected to the first fixing block 304, and the other end of the connecting plate 305 is rotatably connected to the second fixing block 306. The defoaming assembly 2 includes a fixed rod 307 and a nozzle 205; a second fixed block 306 is sleeved and fixed on the fixed rod 307, and the nozzle 205 is fixedly installed on the fixed rod 307; through the above connection method, when the electric push rod 301 is driven, the second fixed block 306 can be driven through the linkage of the push plate 302, the first fixed block 304 and the connecting plate 305, thereby causing the fixed rod 307 and the nozzle 205 fixedly installed on the fixed rod 307 to rotate, thus realizing the adjustment of the spray angle; The defoaming assembly 2 also includes a water tank 201 and a water pump 203. Both the water tank 201 and the water pump 203 are mounted on the forklift 1 to provide water and power for the entire defoaming process. One end of the outlet pipe 202 is connected to the bottom of the water tank 201, and the other end of the outlet pipe 202 is connected to the inlet of the water pump 203. One end of the connecting pipe 204 is connected to the outlet of the water pump 203, and the other end of the connecting pipe 204 is connected to the inlet of the fixed rod 307, thus constructing a complete water circuit. When the water pump 203 starts, the water in the water tank 201 is drawn in through the outlet pipe 202, pressurized, and then transported to the fixed rod 307 through the connecting pipe 204, and finally sprayed out from the nozzle 205 fixedly mounted on the fixed rod 307. The connecting pipe 204 is a flexible hose. This flexible hose connection method can adapt to the rotation of the fixed rod 307 during adjustment, ensuring the continuous connection and sealing of the water circuit. Both the electric push rod 301 and the guide column 303 are fixedly mounted on a bracket above the water tank body 7. This bracket is integrally formed with the water tank body 7 or the main frame of the forklift 1, or welded together, ensuring that the adjustment assembly 3 will not vibrate or shift during operation, thereby improving the accuracy of angle adjustment. To ensure the smooth movement and precise guidance of the push plate 302, two guide columns 303 are used, arranged in parallel. The two ends of the push plate 302 are slidably fitted onto the two guide columns 303. This double guide column structure effectively prevents the push plate 302 from rotating or swaying during sliding, ensuring the accuracy of angle adjustment. A fixed block 304 always performs purely linear motion, thus ensuring the accuracy of the entire linkage mechanism transmission. The bottom of the forklift 1 is equipped with wheels that can move on the track 4. The track 4 is pre-laid at the inspection station. The forklift 1 can easily move the mesh box 6 to the top of the water tank body 7 by following the guide of the track 4, which simplifies the alignment operation and improves the inspection efficiency. The lifting mechanism of the forklift 1 is used to drive the electronic scale 5 and the mesh box 6 to move vertically. By operating the lifting mechanism, the mesh box 6 that has completed dry weight weighing can be smoothly placed into the water tank body 7, or the mesh box 6 that has completed water weighing can be smoothly removed from the water tank body 7.

[0015] Working principle: When conducting the test, the stone material is first placed in the mesh box 6. The lifting mechanism of the forklift 1 is used to move the electronic scale 5 and the mesh box 6 upward, and the initial weight displayed by the electronic scale 5 is recorded. Then, the forklift 1 is moved along the track 4 to the top of the water tank body 7, and the lifting mechanism is used to smoothly immerse the mesh box 6 in the water of the water tank body 7. When it is necessary to remove air bubbles from the surface of the stone, the water pump 203 is started. Water in the water storage tank 201 enters the water pump 203 through the water outlet pipe 202, is pressurized, and is transported to the fixed rod 307 through the connecting pipe 204. Finally, it is sprayed out by the nozzle 205 fixedly installed on the fixed rod 307 to rinse the stone in the water. During the defoaming process, if it is necessary to adjust the spray angle, the electric push rod 301 is started. The extension and retraction of the electric push rod 301 drives the push plate 302 and the first fixed block 304 fixedly connected to it to slide linearly along the guide column 303. Since the first fixing block 304 is rotatably connected to one end of the connecting plate 305, and the other end of the connecting plate 305 is rotatably connected to the second fixing block 306, the linear motion of the first fixing block 304 is converted into the motion of the second fixing block 306 through the transmission of the connecting plate 305. Since the second fixing block 306 is sleeved and fixed on the fixing rod 307, the motion of the second fixing block 306 will directly drive the fixing rod 307 and the nozzle 205 fixed on the fixing rod 307 to rotate synchronously, thereby realizing the precise adjustment of the spray angle and ensuring the effective removal of air bubbles on the surface of the stone. After defoaming is completed and the water surface is still, the weight in the water is recorded again by the electronic scale 5, thus completing the entire on-site testing process.
