Description

Technical Field

[0001] This utility model relates to the field of river management technology, specifically to a riverbed sludge sampling device that facilitates river management. Background Technology

[0002] In the broad field of environmental science and ecological research, riverbed sludge sampling devices are key technical equipment for assessing water pollution, monitoring changes in benthic communities, and studying sediment history. Traditional riverbed sludge sampling devices often face problems such as limited sampling depth, difficulty in ensuring sample integrity, and complex operation. In particular, it is difficult to accurately obtain sludge samples at the target depth under different water depth conditions.

[0003] In response to these challenges, it is particularly important to develop a sampling device that can effectively collect sludge from different depths under varying water conditions. Such a device can not only improve the accuracy and representativeness of sampling, but also provide valuable first-hand data for subsequent laboratory analysis, thereby providing a solid scientific foundation for the formulation of strategies for river management, water quality improvement, and ecological protection. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a riverbed sludge sampling device that is convenient for river management, so as to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A riverbed sludge sampling device for easy river management includes a sampling vessel, the top of which is provided with a lifting and lowering water-detecting structure near its left side.

[0007] The lifting and probing structure includes two horizontal support plates fixedly installed on the top of the sampling vessel. A vertical support plate is fixedly installed on the top of the two horizontal support plates near their left side. Guide rails are fixedly installed on both sides of the inner wall of the vertical support plates. A lifting plate is slidably installed on the outside of the two guide rails. A motor is fixedly installed on the top of the vertical support plate. A ball screw that penetrates into the interior of the lifting plate is fixedly installed at the output end of the motor. The ball screw is rotatably installed inside the upper top wall of the vertical support plate and threadedly connected to the lifting plate. Two electric push rods that penetrate into the top of the lifting plate are fixedly installed at the bottom of the lifting plate. A mud-collecting structure is provided at the bottom of the two electric push rods.

[0008] The mud-collecting structure includes connecting blocks fixedly installed at the bottom of two electric push rods. A housing is fixedly installed between the two connecting blocks. A retrieval groove is opened on the right side wall of the housing. A sampling box located inside the retrieval groove is movably installed inside the housing. A number of partition plates are rotatably installed on the right side of the inner wall of the sampling box. Positioning blocks located at the bottom of the partition plates are fixedly installed on both the front and rear sides of the inner wall of the sampling box. A number of No. 1 metal meshes are fixedly installed inside the back wall of the sampling box. The partition plates divide the interior of the sampling box into multiple mud storage compartments. The multiple No. 1 metal meshes are located inside the multiple mud storage compartments respectively. A No. 2 metal mesh corresponding to the multiple No. 1 metal meshes is fixedly installed inside the back wall of the housing.

[0009] The beneficial effects of this invention are as follows: A ball screw driven by a motor causes the lifting plate to slide down the guide rail, driving the electric push rod and the sludge-collecting structure deeper into the mud layer. The electric push rod can be extended as needed, ensuring the sludge-collecting structure can penetrate mud layers of different depths. After the outer shell is inserted into the mud layer, the sludge enters the sampling box and is isolated and stored by the partition plate, while the wastewater is discharged through the metal mesh, achieving effective separation of sludge and wastewater. After sampling is completed, the electric push rod retracts, and the lifting plate rises to lift the sludge-collecting structure out of the water. This device can flexibly adapt to different water depths, ensuring the acquisition of sludge samples at different depths and meeting diverse sampling needs.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, a reset spring is fixedly installed at the bottom of each of the partition plates, and the reset springs are respectively fixedly installed on the right side of the inner wall of the sampling box.

[0012] Furthermore, a top block is fixedly installed on the top of the sampling box, and a sliding arm that extends through both the upper and lower ends is slidably installed inside the upper top wall of the outer shell, with the sliding arm located on the left side of the top block.

[0013] Furthermore, a base block is fixedly installed on each of the two supporting horizontal plates on opposite sides, and the two base blocks are respectively located at the bottom of the two guide rails.

[0014] Furthermore, the ball screw is rotatably mounted on the top of the rear base block.

[0015] Furthermore, two connecting brackets are fixedly installed between each of the two supporting horizontal plates and the supporting vertical plates. Attached Figure Description

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Example 1, as Figures 1 to 7 As shown, a riverbed sludge sampling device for easy river management includes a sampling vessel 1, with a lifting and probing structure located on the top of the sampling vessel 1 near its left side.

[0027] Specifically, the lifting and probing structure includes two supporting horizontal plates 2 fixedly installed on the top of the sampling vessel 1. A supporting vertical plate 3 is fixedly installed on the top of the two supporting horizontal plates 2 near its left side. Guide rails 4 are fixedly installed on both sides of the inner wall of the supporting vertical plate 3. A lifting plate 5 is slidably installed on the outside of the two guide rails 4. A motor 301 is fixedly installed on the top of the supporting vertical plate 3. A ball screw 302 that penetrates into the interior of the lifting plate 5 is fixedly installed at the output end of the motor 301. The ball screw 302 is rotatably installed inside the upper top wall of the supporting vertical plate 3 and threadedly connected to the lifting plate 5. Two electric push rods 6 that penetrate into the top of the lifting plate 5 are fixedly installed at the bottom of the lifting plate 5. A mud-taking structure is provided at the bottom of the two electric push rods 6.

[0028] Specifically, the mud-collecting structure includes connecting blocks 7 fixedly installed at the bottom of two electric push rods 6, a housing 8 fixedly installed between the two connecting blocks 7, a retrieval groove on the right side wall of the housing 8, a sampling box 9 movably installed inside the housing 8 and located inside the retrieval groove, a number of partition plates 10 rotatably installed on the right side of the inner wall of the sampling box 9, positioning blocks 11 fixedly installed on the front and rear sides of the inner wall of the sampling box 9 at the bottom of the multiple partition plates 10, a number of first-order metal meshes 12 fixedly installed inside the back wall of the sampling box 9, the partition plates 10 dividing the interior of the sampling box 9 into multiple mud storage compartments, the multiple first-order metal meshes 12 being located inside the multiple mud storage compartments respectively, and a second-order metal mesh 13 corresponding to the multiple first-order metal meshes 12 fixedly installed inside the back wall of the housing 8.

[0029] In use, the sampling vessel 1 can carry the lifting and lowering water exploration structure and the mud sampling structure to collect samples in different water areas. Upon reaching the designated water area, the motor 301 is activated, driving the ball screw 302 to rotate forward, causing the lifting plate 5 to slide downwards outside the two guide rails 4. The lifting plate 5 then lowers the two electric push rods 6 and the mud sampling structure, allowing the mud sampling structure to penetrate the mud layer for sampling. When the length is insufficient, the two electric push rods 6 inside the lifting plate 5 are activated, extending the penetration length of the mud sampling structure. Once the outer shell 8 of the mud sampling structure is inserted into the mud layer, the sludge can be sampled. The sludge enters the sampling box 9 and pushes up the multiple partition plates 10 to be stored inside the sampling box 9. At this time, the sewage entering the sampling box 9 is discharged through multiple No. 1 metal mesh 12 and No. 2 metal mesh 13, while the sludge is isolated inside the sampling box 9. After sampling is completed, the two electric push rods 6 are retracted to remove the sludge removal structure from the sludge layer. The motor 301 drives the ball screw 302 to rotate in the opposite direction to raise the lifting plate 5. Then, the lifting plate 5 drives the two electric push rods 6 and the sludge removal structure to emerge from the water. Finally, the sampling box 9 and the sludge sample can be removed from the inside of the outer shell 8.

[0030] Example 2, as Figure 4As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0031] Each of the multiple partition plates 10 has a reset spring 14 fixedly installed at its bottom, and the multiple reset springs 14 are respectively fixedly installed on the right side of the inner wall of the sampling box 9.

[0032] With this configuration, the retraction of multiple sampling boxes 9 can pull multiple partition plates 10 to reset. The reset of multiple partition plates 10 can separate and block the sludge samples inside the sampling boxes 9, preventing the sludge samples inside the sampling boxes 9 from sliding outward when the outer shell 8 and the sampling boxes 9 are pulled upward.

[0033] Example 3, as Figures 3-6 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0034] A top block 15 is fixedly installed on the top of the sampling box 9, and a sliding arm 16 is slidably installed inside the upper top wall of the outer shell 8, extending through its upper and lower ends. The sliding arm 16 is located on the left side of the top block 15.

[0035] With this configuration, by holding the top of the sliding handle 16 and pushing it to the right, the top block 15 and the sampling box 9 at the bottom of the top block 15 can be moved to the right, and the sampling box 9 can be easily removed from the inside of the outer casing 8.

[0036] Example 4, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0037] A base block 17 is fixedly installed on each of the two supporting horizontal plates 2 on opposite sides, and the two base blocks 17 are located at the bottom of the two guide rails 4 respectively.

[0038] This configuration restricts the descent position of the lifting plate 5 by using two bottom blocks 17, preventing it from detaching from the two guide rails 4.

[0039] Example 5, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0040] The ball screw 302 is rotatably mounted on the top of the rear base block 17.

[0041] This configuration allows the bottom of the ball screw 302 to be supported by the rear base block 17.

[0042] Example 6, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0043] Two connecting brackets 18 are fixedly installed between the two horizontal support plates 2 and the vertical support plates 3.

[0044] With this setup, the vertical support plate 3 and the two horizontal support plates 2 are stably connected together by the installed connecting bracket 18.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
