Description

Technical Field

[0001] This utility model belongs to the field of forest litter technology, and in particular relates to a device for measuring the water-holding capacity of litter. Background Technology

[0002] Forests are the largest terrestrial ecosystems on Earth. Due to global warming and the continuous deterioration of water resources, the water conservation function of forests has always been a major concern. The litter layer is an important component of forest structure, serving as a crucial cover and protective layer on the forest surface. It provides vital protection for the accumulation of soil nutrients and the healthy growth of trees. At the same time, as the second active layer of forest hydrology, it plays a significant role in improving soil structure, intercepting rainfall, protecting the soil from raindrop impact, inhibiting water evaporation, and mitigating surface runoff. Therefore, improving the water retention capacity of forest areas has become a research hotspot.

[0003] However, during the soaking process of litter, most of the collected litter samples are usually quite dry and have been exposed to the elements for a period of time, resulting in low density and relatively light weight. This often leads to litter particles floating on the water surface during the crucial soaking step for testing their water-holding capacity. Previously, the soaking was done manually, which prevented the litter particles from sinking completely and achieving sufficient and uniform soaking. Furthermore, this process was time-consuming and laborious, as it was impossible to remove all the litter particles from the water at the same time, resulting in significant experimental errors. Utility Model Content

[0004] The purpose of this invention is to provide a device for measuring the water-holding capacity of fallen materials, so as to achieve complete immersion of fallen materials in water for thorough and uniform soaking, and to ensure that all fallen materials can be taken out of the water at the same time, thereby improving the accuracy of the experiment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a device for measuring the water-holding capacity of litter, comprising:

[0007] The immersion tank body has multiple cavities inside for storing water;

[0008] A pressing part, wherein the pressing part is installed on the top of the immersion tank body and is located above the plurality of cavities; and

[0009] The detection unit is provided in multiple ways. The multiple detection units are installed in a matrix on the top of the immersion tank body, and all of the multiple detection units are located on the top of the pressing part.

[0010] Furthermore, the pressing part includes:

[0011] A lifting assembly, which is vertically fixed to the center of the immersion tank body; and

[0012] A positioning component, which is connected to the extension end of the lifting component via a connecting component.

[0013] Furthermore, the lifting assembly includes an electric push rod, the cylinder of which is fixed to the inner wall of the center of the immersion tank body; the connecting assembly includes a connecting plate and a connecting frame, the connecting plate is fixed to the extended end of the electric push rod, and the connecting frame is fixed to the outer wall of the connecting plate; the positioning assembly is fixed to the connecting frame.

[0014] Furthermore, the positioning component includes multiple L-shaped rods and multiple positioning rings. The multiple L-shaped rods are fixed to the bottom of the connecting frame in a matrix, and the multiple positioning rings are fixed to the extended ends of the multiple L-shaped rods and correspond to the positions of the multiple cavities.

[0015] Furthermore, the detection unit includes:

[0016] An adjustment assembly, fixed to the top of the immersion tank body; and

[0017] A detection component is mounted on the adjustment component.

[0018] Furthermore, the adjustment assembly includes an adjustment rod, an adjustment seat, and a threaded rod. The adjustment rod is vertically fixed to the top surface of the immersion tank body. The adjustment seat is sleeved on the outer wall of the adjustment rod and slidably connected to it. The threaded rod is threadedly connected to the adjustment seat and passes through the adjustment seat to contact the adjustment rod. A knob is fixed to the extended end of the threaded rod.

[0019] Furthermore, the detection assembly includes a fixed plate, an electronic spring scale, a pull ring, a pull rope, a sealing head, and a detection sleeve. The fixed plate is horizontally fixed on the adjusting seat; the electronic spring scale is fixed to the bottom of the fixed plate; the pull ring is fixed to the bottom detection ring of the electronic spring scale; one end of the pull rope is connected to the pull ring, and the other end of the pull rope is connected to the sealing head; the detection sleeve is threadedly connected to the sealing head, and the outer wall of the detection sleeve has multiple filter holes.

[0020] This utility model has the following beneficial effects:

[0021] 1. By setting up a pressing part, after the fallen material is loaded into the detection sleeve, the height of the detection sleeve is adjusted by the detection part so that the detection sleeve can float on the water surface and leave extra length for the pull rope. At this time, the electric push rod can be driven to move the connecting plate and connecting frame downward. The inner diameter of the positioning ring is larger than the outer diameter of the detection sleeve, so that the positioning rings on multiple L-shaped rods squeeze the detection sleeve downward, so that the detection sleeve can be completely submerged in the water for sufficient soaking. This avoids the fallen material being too light and too low in density, which would cause it to float on the water surface, thereby ensuring more accurate detection data.

[0022] 2. With a detection unit, after placing the waste material inside the detection sleeve, the sealing head can be turned to place the waste material inside the detection sleeve. The filter holes prevent the waste material from leaking out while allowing water to enter the detection sleeve to soak the waste material. The electronic spring scale can detect the weight of the detection sleeve and compare and record the weight of the waste material before and after soaking to calculate the water-holding capacity of the waste material. When the knob is turned to drive the threaded rod to rotate, it will cause the threaded rod to fit tightly against the outer wall of the adjusting rod, thereby fixing the height of the adjusting seat. The height of the waste material can be adjusted to facilitate drainage and also provide sufficient pull rope length for the wetted waste material.

[0023] 3. To ensure that all fallen debris can be removed from the water at the same time, thus improving the accuracy of the experiment.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figure 1-5 As shown, this utility model is a device for measuring the water-holding capacity of litter, comprising:

[0039] The immersion tank body 1 has several cavities inside for storing water.

[0040] Pressing part 2 is installed on the top of the immersion tank body 1 and is located above multiple cavities of the immersion tank body 1; and

[0041] The detection unit 3 is provided in multiple ways. The multiple detection units 3 are installed in a matrix on the top of the immersion tank body 1. The multiple detection units 3 are located on the top of the pressing unit 2.

[0042] The system includes multiple cavities for storing water and immersing fallen debris, a pressing unit 2 for pressing the fallen debris downwards so that it can be completely submerged in water, and multiple detection units 3 for weighing multiple groups of fallen debris. The fallen debris is weighed before immersion in water, and after immersion, the detection units 3 adjust the height of the fallen debris. After each immersion period, the fallen debris is taken out, drained, and weighed again to test its water-holding capacity.

[0043] The pressing part 2 includes:

[0044] Lifting assembly 21 is fixedly installed at the center of the immersion tank body 1, and the top of the lifting assembly 21 extends to the top center of the immersion tank body 1; and

[0045] Positioning component 22 is connected to the extended end of lifting component 21 via a connecting component;

[0046] The lifting component 21 can drive the positioning component 22 to move up or down, and press the fallen material into the water through the positioning component 22.

[0047] The lifting assembly 21 includes an electric push rod 211, the cylinder of which is fixedly connected to the inner wall of the immersion tank body 1. The connecting assembly includes a connecting plate 212 and a connecting frame 213. The connecting plate 212 is fixed to the extended end of the electric push rod 211, and the connecting frame 213 is fixed to the outer wall of the connecting plate 212. The positioning assembly 22 is fixed to the connecting frame 213.

[0048] The electric push rod 211 can drive the connecting plate 212 and the connecting frame 213 to move up and down, serving as a driving source for pressing down fallen objects.

[0049] The positioning assembly 22 includes multiple L-shaped rods 221 and multiple positioning rings 222. The multiple L-shaped rods 221 are fixed in a matrix to the bottom of the connecting frame 213, and the multiple positioning rings 222 are fixed to the extended ends of the multiple L-shaped rods 221 and correspond to the positions of multiple cavities.

[0050] When the positioning ring 222 moves downward, it presses the fallen material into the water. By providing the pressing part 2, the detection sleeve 326 can be fully submerged in the water for thorough soaking, avoiding the fallen material from being too light and having too low density, which would cause it to float on the water surface, thus ensuring more accurate detection data.

[0051] Testing unit 3 includes:

[0052] Adjustment component 31, which is fixed to the top of the immersion tank body 1; and

[0053] Detection component 32 is mounted on adjustment component 31;

[0054] The adjusting component 31 is used to adjust the height of the fallen material so that it can be submerged in water. At the same time, the adjusting component 31 can also be used to drain the fallen material after soaking. The detection component 32 is used to measure the weight of the fallen material.

[0055] The adjustment assembly 31 includes an adjustment rod 311, an adjustment seat 312, and a threaded rod 313. The adjustment rod 311 is vertically fixed to the top surface of the immersion tank body 1. The adjustment seat 312 is sleeved on the outer wall of the adjustment rod 311 and slidably connected to it. The threaded rod 313 is threadedly connected to the adjustment seat 312 and passes through the adjustment seat 312 to contact the adjustment rod 311. A knob 314 is fixed to the extended end of the threaded rod 313.

[0056] By turning the knob 314, the threaded rod 313 moves away from or closer to the adjusting rod 311, and the adjusting seat 312 slides up and down to fix the height position of the adjusting seat 312, thereby adjusting the height of the fallen material for soaking or draining the fallen material.

[0057] The detection assembly 32 includes a fixing plate 321, an electronic spring scale 322, a pull ring 323, a pull rope 324, a sealing head 325, and a detection sleeve 326. The fixing plate 321 is horizontally fixed on the adjusting seat 312; the electronic spring scale 322 is fixed to the bottom of the fixing plate 321; the pull ring 323 is fixed to the bottom detection ring of the electronic spring scale 322; one end of the pull rope 324 is connected to the pull ring 323, and the other end of the pull rope 324 is connected to the sealing head 325; the detection sleeve 326 is threadedly connected to the sealing head 325, and the outer wall of the detection sleeve 326 is provided with multiple filter holes 327.

[0058] The detection sleeve 326 is used to fill with fallen debris. The pull rope 324 and pull ring 323 work together to fix the detection sleeve 326 filled with fallen debris to the bottom detection ring of the electronic spring scale 322 through the sealing head 325 for weighing. After the detection sleeve 326 is immersed in water, water is poured into the inside of the detection sleeve 326 through the filter hole 327 to wet the fallen debris. With the detection part 3, the electronic spring scale 322 can detect the weight of the detection sleeve 326 and compare and record the weight of the fallen debris before and after soaking to calculate the water-holding capacity of the fallen debris. When the knob 314 is turned to drive the threaded rod 313 to rotate, the threaded rod 313 will be driven to fit tightly against the outer wall of the adjusting rod 311, thereby fixing the height of the adjusting seat 312. The height of the fallen debris can be adjusted to facilitate drainage, and sufficient length of the pull rope 324 can be reserved for wetting the fallen debris.

[0059] One specific application of this embodiment is as follows: By providing the pressing part 2, after the fallen material is loaded into the detection sleeve 326, the height of the detection sleeve 326 is adjusted by the detection part 3, so that the detection sleeve 326 can float on the water surface and leave extra length of the pull rope 324. At this time, the electric push rod 211 can be driven to move the connecting plate 212 and the connecting frame 213 downward. The inner diameter of the positioning ring 222 is larger than the outer diameter of the detection sleeve 326, so that the positioning rings 222 on the multiple L-shaped rods 221 squeeze the detection sleeve 326 downward, so that the detection sleeve 326 can be completely submerged in the water for sufficient soaking, avoiding the fallen material from being too light and having too low density and suspending on the water surface, thereby ensuring more accurate detection data.

[0060] With the detection unit 3, after the fallen material is placed inside the detection sleeve 326, the sealing head 325 can be turned to place the fallen material inside the detection sleeve 326. The filter hole 327 prevents the fallen material from leaking out while allowing water to enter the detection sleeve 326 to soak the fallen material. The electronic spring scale 322 can detect the weight of the detection sleeve 326 and compare and record the weight of the fallen material before and after soaking to calculate the water-holding capacity of the fallen material. When the knob 314 is turned to drive the threaded rod 313 to rotate, the threaded rod 313 will be driven to fit tightly against the outer wall of the adjusting rod 311, thereby fixing the height of the adjusting seat 312. The height of the fallen material can be adjusted to facilitate drainage, and sufficient length of the pull rope 324 can be reserved for the soaking of the fallen material.
