Description

Technical Field

[0001] This utility model relates to the field of environmental management technology, and in particular to a sludge sampling device for environmental management. Background Technology

[0002] Environmental management is a comprehensive activity that uses planning, organization, coordination, control, and supervision to achieve expected environmental goals. Environmental management involves various environmental factors such as soil, water, atmosphere, and organisms. In the process of environmental management, especially in the management of the water environment, it is usually necessary to use corresponding sludge sampling devices to sample the sludge at the bottom of the water body so that the sludge can be analyzed after sampling to determine the pollution status of the water body.

[0003] For example, utility model patent application number 202320923163.1 discloses a sludge sampling device, including a fixed box. A through groove is provided on one side surface of the fixed box, and a lowering mechanism is provided inside the fixed box. The lowering mechanism includes a threaded rod, which is located inside the fixed box. A motor is provided at the top of the threaded rod, and a threaded sleeve is provided on the outside of the threaded rod. A connecting slide rod is provided on one side of the threaded sleeve, and a lower pressure plate is connected to one end of the connecting slide rod.

[0004] Based on existing technology, most existing silt sampling devices have fixed structures, making it inconvenient to adjust the extension distance of the sampling box. This makes it difficult to horizontally adjust the sampling position of underwater silt according to actual sampling needs, resulting in low practicality. Furthermore, adjusting the sampling depth by splicing sampling rods is not convenient enough and is inconvenient to use. Therefore, this utility model proposes a silt sampling device for environmental management to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a sludge sampling device for environmental management, which solves the problems that existing sludge sampling devices are not convenient for horizontally adjusting the sampling position of underwater sludge according to actual sampling needs, and that adjusting the sampling depth by using spliced ​​sampling rods is not convenient enough.

[0006] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a sludge sampling device for environmental management, including a movable base, a first telescopic plate driven to rotate by a first motor being rotatably connected to the top of the movable base, a second telescopic plate being slidably disposed inside the first telescopic plate, a third telescopic plate being slidably disposed inside the second telescopic plate, the first telescopic plate, the second telescopic plate and the third telescopic plate being fixed together by a positioning locking mechanism, a drive box being fixed to one end of the third telescopic plate located outside the second telescopic plate, a sampling bucket being suspended below the drive box by a winding and hoisting mechanism, a drilling cone being provided at the bottom of the sampling bucket being driven to rise and fall by a lifting mechanism, and a sampling tube being fixed at the top of the drilling cone and slidably disposed inside the sampling bucket.

[0007] A further improvement is that the lifting mechanism includes an electric motor fixed to the top of the inside of the sampling barrel and a partition fixed to the middle position inside the sampling barrel. The output end of the electric motor is fixed with a lead screw that is rotatably connected to the partition. A threaded plate is threaded onto the lead screw. A push rod that slides through the partition is symmetrically fixed between the threaded plate and the drilling cone.

[0008] A further improvement is that a counterweight ring is fixed to the lower part of the outer wall of the sampling bucket, and a counterweight cone that is equidistantly distributed in a ring shape is fixed to the bottom end of the counterweight ring.

[0009] A further improvement is that the take-up and lifting mechanism includes a take-up roller rotatably connected inside the drive box and driven to rotate by a second motor, and a lifting rope wound around the take-up roller. The end of the lifting rope away from the take-up roller slides through to the outside of the drive box and is fixed to the top of the sampling barrel.

[0010] A further improvement is that the positioning and locking mechanism includes a positioning bolt threaded through the top of the first and second telescopic plates and positioning holes equidistantly opened at the top of the second and third telescopic plates, wherein the positioning holes are adapted to the positioning bolt.

[0011] A further improvement is that: a drive sprocket is fixedly sleeved on the output shaft of the first motor, a support shaft is fixedly sleeved at the bottom of the first telescopic plate, the lower part of the support shaft passes through the interior of the movable base through a bearing and is fixedly sleeved on a driven sprocket, and a chain is sleeved on both the drive sprocket and the driven sprocket.

[0012] Further improvements include: symmetrically fixed supporting balls at the bottom end of the first telescopic plate, and a push-pull handle fixed on the side of the movable base away from the drive box.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a movable base, a second telescopic plate is slidably arranged inside the first telescopic plate, and a third telescopic plate is slidably arranged inside the second telescopic plate. At the same time, the third telescopic plate is positioned and fixed by a positioning and locking mechanism, so that the drive box at the end of the third telescopic plate and the sampling bucket suspended below it can be easily adjusted horizontally. This makes it easy to adjust the sampling position of underwater silt horizontally according to the actual sampling needs, which is highly practical. Moreover, the sampling bucket is driven to rise and fall freely by the unwinding and hoisting mechanism, which is more convenient and easy to use than the traditional splicing and adjustment method.

Detailed Implementation

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this embodiment provides a sludge sampling device for environmental management, including a movable base 1 with casters at the bottom and a first motor 2 fixed inside the movable base 1. A hollow first telescopic plate 3 is rotatably connected to the top of the movable base 1, and the first telescopic plate 3 is driven to rotate by the first motor 2. A hollow second telescopic plate 4 is slidably disposed inside the first telescopic plate 3, and the right end of the second telescopic plate 4 slides through to the outside of the first telescopic plate 3, allowing the second telescopic plate 4 to slide and adjust within the first telescopic plate 3. A third telescopic plate 5 is slidably disposed inside the second telescopic plate 4, and the right end of the third telescopic plate 5 slides through to the outside of the second telescopic plate 4 and is fixed with a hollow drive box 6 by bolts, allowing the third telescopic plate 5 to slide and adjust within the second telescopic plate 4. The first telescopic plate 3, the second telescopic plate 4, and the third telescopic plate 5 are fixed together by a positioning locking mechanism, facilitating fixation after sliding adjustment. Below the drive box 6... A sampling bucket 7 for sludge sampling is provided. The sampling bucket 7 is driven and raised and lowered by a winding and lifting mechanism on the drive box 6. The sampling bucket 7 has a lifting mechanism inside. The bottom of the sampling bucket 7 has a conical drilling cone 8, which is driven and raised and lowered by the lifting mechanism. The top of the drilling cone 8 is fixed with a sampling tube 9 for containing sludge samples. The sampling tube 9 is slidably disposed inside the sampling bucket 7 and can be raised and lowered synchronously with the drilling cone 8. A second telescopic plate 4 is slidably disposed in the first telescopic plate 3, and a third telescopic plate 5 is slidably disposed in the second telescopic plate 4. At the same time, the third telescopic plate 5 is positioned and fixed by a positioning and locking mechanism. This makes it easy to adjust the horizontal extension and retraction of the drive box 6 at the end of the third telescopic plate 5 and the sampling bucket 7 suspended below it. This makes it easy to adjust the sampling position of underwater sludge horizontally according to the actual sampling needs. The sampling bucket 7 is driven to rise and fall freely by the winding and lifting mechanism, which is more convenient than the traditional splicing and adjustment method.

[0022] The lifting mechanism includes an electric motor 10 and a partition 11. The electric motor 10 is fixed to the top of the inside of the sampling barrel 7 by screws, and the partition 11 is fixed to the middle position inside the sampling barrel 7. A lead screw 12 is fixed to the output end of the electric motor 10. The bottom end of the lead screw 12 is rotatably connected to the top of the partition 11 through a bearing. A threaded plate 13 is threaded onto the lead screw 12. A push rod 14 is symmetrically fixed to the bottom end of the threaded plate 13. The bottom end of the push rod 14 slides through the partition 11 and is fixed to the top of the drilling cone 8. The electric motor 10 drives the lead screw 12 to rotate, which causes the threaded plate 13 threaded onto the lead screw 12 to drive the push rod 14 to move up and down. The push rod 14 then drives the drilling cone 8 to move up and down.

[0023] A counterweight ring 15 is welded and fixed to the lower part of the outer wall of the sampling bucket 7, which serves to increase the weight and make it easier for the sampling bucket 7 to fall into the bottom of the water. A counterweight cone 16 is fixed to the bottom of the counterweight ring 15, and the counterweight cone 16 is distributed in a ring at equal intervals on the counterweight ring 15, which also serves to increase the weight and makes it easier to insert into the silt at the bottom of the water.

[0024] The take-up and lifting mechanism includes a second motor 17, a take-up roller 18, and a lifting rope 19. The second motor 17 is fixed to the outer right side of the drive box 6 by bolts. The take-up roller 18 is rotatably connected to the inside of the drive box 6 and is driven to rotate by the second motor 17. The lifting rope 19 is wrapped around the take-up roller 18. The end of the lifting rope 19 away from the take-up roller 18 slides through to the outside of the drive box 6 and is fixed to the top of the sampling barrel 7. The bottom of the drive box 6 has a through hole adapted to the lifting rope 19. The take-up roller 18 is driven to rotate by the second motor 17 to unwind the lifting rope 19, so as to lower the sampling barrel 7. The take-up roller 18 is driven to rotate in the opposite direction to wind up the lifting rope 19, so as to lift the sampling barrel 7.

[0025] The positioning and locking mechanism includes positioning bolts 20 and positioning holes 21. The positioning bolts 20 are provided in two sets and are threaded through the top right side of the first telescopic plate 3 and the top right side of the second telescopic plate 4, respectively. The positioning holes 21 are equally spaced at the top of the second telescopic plate 4 and the third telescopic plate 5 and are adapted to the positioning bolts 20. By screwing the positioning bolts 20 into the positioning holes 21, the positioning and fixing of the first telescopic plate 3, the second telescopic plate 4 and the third telescopic plate 5 are achieved.

[0026] A drive sprocket 22 is fixedly sleeved on the output shaft of the first motor 2. A support shaft 23 is fixedly sleeved at the bottom of the first telescopic plate 3. The lower part of the support shaft 23 passes through the interior of the movable base 1 through a bearing and is fixedly sleeved with a driven sprocket 24 that matches the position of the drive sprocket 22. A chain is sleeved on both the drive sprocket 22 and the driven sprocket 24 and they are connected by chain drive. The drive sprocket 22 is driven to rotate by the first motor 2, and the drive sprocket 22 then drives the driven sprocket 24 to rotate through the chain, which in turn drives the first telescopic plate 3 to rotate through the support shaft 23.

[0027] Four sets of symmetrically distributed support balls 25 are fixed at the bottom of the first telescopic plate 3, which provide auxiliary support for the first telescopic plate 3. A push-pull handle 26 is fixed on the side of the movable base 1 away from the drive box 6, which makes it easy for the user to push the device to move, and the weight of the movable base 1 is sufficient to ensure its stability.

[0028] When underwater sludge sampling is required during environmental management, the device is first moved to the shore of the area to be sampled. Then, the third telescopic plate 5 is slid out from the second telescopic plate 4, and the second telescopic plate 4 is slid out from the first telescopic plate 3 until the drive box 6 moves to the corresponding position above the water surface (at this time, the sampling bucket 7 is directly above the sampling location). After adjustment, the first telescopic plate 3, the second telescopic plate 4, and the third telescopic plate 5 are fixed together using the positioning and locking mechanism. Then, the winding and hoisting mechanism is activated to drive the sampling bucket 7 downwards, allowing... The sampling bucket 7 is lowered into the water until it embeds itself in the silt at the bottom due to its own weight. Then, the lifting mechanism is activated to drive the drilling cone 8 to descend until it drives the sampling tube 9 into the sludge. After the sampling tube 9 is removed from the sampling bucket 7, the sludge, due to its fluidity, will flow into the sampling tube 9 from the opening at the top. Then, the lifting mechanism is activated to drive the drilling cone 8 to rise until the sampling tube 9 retracts into the sampling bucket 7. After that, the unwinding and hoisting mechanism is activated to drive the sampling bucket 7 to rise and reset. The silt in the sampling tube 9 is the sludge sample. After it is removed, the sludge sampling is completed.
