Description

Technical Field

[0001] The invention relates to a collection equipment technology, and in particular to a water sampler for a multi-stage quasi-in-situ groundwater repair device. Background Art

[0002] Groundwater remediation refers to the use of extraction, gas extraction, bioremediation, permeable reaction wall and other technologies to restore contaminated groundwater to its original water quality. Groundwater resources are an important part of water resources. At present, groundwater pollution occurs frequently in my country. The development of groundwater pollution control and remediation work is of great significance to the sustainable utilization of groundwater resources.

[0003] In the Chinese invention patent with publication number CN118443387A, a stratified water sampler is disclosed, which includes a mounting bracket, multiple water sampling tanks, a locking mechanism, a detection mechanism and a control module. After the stratified water sampler is placed underwater, the detection mechanism detects the underwater depth of the stratified water sampler in real time. When the stratified water sampler reaches a predetermined depth, the first locking mechanism is controlled to disconnect through the control module so that the first float is disconnected from the mounting bracket. The first float quickly floats to the water surface due to its own buoyancy, so that the staff on the water surface can observe and confirm that the stratified water sampler has reached the predetermined depth, and then control the water sampling tank to collect water at the current depth. Either only one first float or multiple first floats can be set, and when the stratified water sampler reaches different depths, the first floats are released respectively, so as to collect water samples at different depths. When the stratified water sampler reaches a predetermined depth, either only one first float or multiple first floats can be released at the same time. To sum up, the stratified water sampler can set different numbers of first floats as needed to achieve sampling at different depths, thereby obtaining multi-layer water samples, which helps to more accurately understand the properties and composition of the water body, making the water sampling process more efficient and flexible, and able to obtain more accurate water sample data.

[0004] When the existing equipment is in use, it is difficult to independently adjust the water samplers at different levels due to the different water flow rates and water quality characteristics in different water layers, which results in the water samplers being unable to reach the optimal state and unable to perform accurate extraction. At the same time, when collecting water, the water sampling port is easily blocked by particulate matter or other substances, thereby greatly reducing the collection efficiency. Therefore, a water sampler for a multi-stage quasi-in-situ groundwater remediation device has been developed. Summary of the invention

[0023] Example: See Figure 1-Figure 8 A water sampler for a multi-stage quasi-in-situ groundwater remediation device comprises a main body 1, a connecting block 11 is arranged at the upper end of the main body 1, and a collecting component 2 is arranged on the inner wall of the main body 1, through which water is collected.

[0024] In this solution, the connection block 11 is arranged on the traction rod and is distributed at different depths according to actual conditions to make it suitable for the current scene, and the connection block 11 is tightly connected to the traction rod by means of fixing parts such as buckles.

[0025] Furthermore, the collecting assembly 2 includes a fixed block 21 connected to the main body 1, a limiting rod 22 is provided at the end of the fixed block 21, and a turntable 23 is provided at the end of the limiting rod 22; a first turntable 24 is rotatably installed at the end of the fixed block 21, a rotating shaft 27 is provided at the end of the first turntable 24, and a second turntable 25 is rotatably installed on the outer surface of the rotating shaft 27, a transmission rope 231 is provided on the outer surface of the turntable 23, and the outer surface of the transmission rope 231 is respectively connected to the outer surfaces of the first turntable 24 and the second turntable 25.

[0026] In this embodiment, a device with power output, such as a motor, is provided at the end of the limit rod 22 and is connected to an external control device. When the motor is started, the turntable 23 provided at its output end is synchronously driven to rotate.

[0027] At the same time, the outer surface of the turntable 23 drives the first rotating block 24 and the second rotating block 25 to rotate through the transmission rope 231, so that the first rotating block 24 and the second rotating block 25 rotate in opposite directions, and the rotating shaft 27 set at the end of the first rotating block 24 is connected to the internal rotation of the second rotating block 25, so that the first rotating block 24 and the second rotating block 25 do not interfere with each other when rotating.

[0028] Furthermore, a transmission cylinder 251 is provided at the end of the second rotating block 25, and a positioning rod 252 is provided on the outer surface of the transmission cylinder 251, the end of the positioning rod 252 is connected to the outer surface of the fixed block 21, and a rotating cylinder 26 is provided at the end of the transmission cylinder 251, and the outer surface of the rotating cylinder 26 is rotatably connected to the inner wall of the main body 1.

[0029] Specifically, the second rotating block 25 is limited by the transmission cylinder 251 so that the second rotating block 25 is always located on the outer surface of the rotating shaft 27 . Meanwhile, the transmission cylinder 251 is supported by the positioning rod 252 to ensure overall stability.

[0030] Since the end of the transmission cylinder 251 is connected to the rotating cylinder 26, the rotating cylinder 26 rotates synchronously with the second rotating block 25. At the same time, the outer surface of the rotating cylinder 26 is provided with rubber or other sealing components to keep the connection between the rotating cylinder 26 and the main body 1 sealed.

[0031] Furthermore, a through hole 261 is provided on the outer surface of the rotating drum 26 , a thread 262 is provided on the inner wall of the rotating drum 26 , and a ring 28 is provided on the outer surface of the rotating drum 26 .

[0032] Specifically, when the drum 26 rotates, it synchronously drives the ring 28 arranged on its outer surface to rotate. At the same time, a scraper is arranged at the end of the ring 28. When the ring 28 rotates, impurities and particulate matter around the drum 26 are pushed out, so that the impurity content in the collected water body is reduced and the blockage phenomenon is reduced.

[0033] Furthermore, the outer surface of the rotating shaft 27 is slidably connected to the inner wall of the transmission cylinder 251 , and the end of the rotating shaft 27 penetrates and extends to the interior of the rotating cylinder 26 .

[0034] Specifically, the rotating shaft 27 provides power output for the processing assembly 3, so that the processing assembly 3 and the rotating drum 26 rotate in opposite directions.

[0035] Furthermore, the processing assembly 3 is assembled in the inner cavity of the rotating drum 26, and the collected water is screened by the processing assembly 3. The processing assembly 3 includes a docking block 31 connected to the rotating shaft 27, and a clamping tube 32 is provided at the end of the docking block 31, and a positioning shaft 34 is provided at one end of the clamping tube 32 away from the docking block 31.

[0036] In this embodiment, when the docking block 31 rotates, the clamping sleeve 32 disposed at the end thereof is synchronously driven to rotate, wherein the positioning shaft 34 is rotatably mounted on the inner wall of the clamping sleeve 32 .

[0037] Furthermore, the outer surface of the clamping tube 32 is provided with multiple groups of protection rods 33, and the multiple groups of protection rods 33 are evenly distributed on the outer surface of the clamping tube 32. The end of the protection rod 33 is provided with a movable block 38, and the end of the movable block 38 away from the protection rod 33 is provided with an adjustment plate 381.

[0038] Specifically, when the clamping tube 32 rotates, the protection rod 33 disposed on the outer surface thereof is driven to rotate, and the movable block 38 and the adjustment plate 381 disposed on the movable block 38 are driven to move.

[0039] The inner wall of the drum 26 is provided with a mesh plate or other screening components, and the outer surface of the mesh plate is in contact with the outer surface of the adjustment plate 381. The particles on the mesh plate are removed by the adjustment plate 381 to avoid blockage due to accumulation of particles.

[0040] Furthermore, a support rod 35 corresponding to the protection rod 33 is provided on the outer surface of the end of the positioning shaft 34 away from the clamping cylinder 32. A rotating block 36 is provided at the end of the support rod 35, and a transmission rod 37 is provided at the end of the rotating block 36. The end of the transmission rod 37 away from the rotating block 36 is connected to the end of the movable block 38.

[0041] Specifically, when the movable block 38 moves, the transmission rod 37 installed at its end is synchronously driven to move. Since the end of the transmission rod 37 is connected to the rotating block 36, the transmission rod 37 rotates around the rotating block 36. At the same time, the entire clamping cylinder 32 slides along the outer surface of the positioning shaft 34, thereby adjusting the angle of the adjustment plate 381 to achieve regulation of the water flow rate.

[0042] The transmission rod 37 is a telescopic rod, and the overall length can be adjusted according to actual conditions to make it suitable for the current scene.

[0043] Furthermore, a connecting tube 39 is provided at the end of the positioning shaft 34, a telescopic member 391 is provided on the inner wall of the connecting tube 39, and a slider 392 is provided at the output end of the telescopic member 391. A convex block 393 is provided on the inner wall of the connecting tube 39, and a slot 397 corresponding to the convex block 393 is provided on the outer surface of the slider 392, and the inner wall of the slot 397 is slidably connected to the outer surface of the convex block 393.

[0044] Specifically, the telescopic member 391 is a device with power output such as an electric telescopic rod, and is connected to an external control device. When the telescopic member 391 is started, it synchronously drives the slider 392 set at its output end to move, and the activity trajectory of the slider 392 is limited by the protrusion 393.

[0045] When the slider 392 is engaged with the protrusion 393, the positioning shaft 34 is in a fixed state when the docking block 31 rotates, so that the angle of the adjustment plate 381 can be adjusted. When the slider 392 is separated from the protrusion 393, when the docking block 31 rotates, the adjustment plate 381 rotates synchronously with it and clears the particles accumulated on the grid plate.

[0046] Furthermore, a stretching rod 394 is provided at the end of the slider 392, and a baffle 395 is provided at the end of the stretching rod 394. The outer surface of the baffle 395 is in contact with the inner wall of the thread 262. At the same time, an adjusting rod 396 is provided at the end of the baffle 395, and the end of the adjusting rod 396 is connected to the inner wall of the rotating drum 26.

[0047] Specifically, the stretching rod 394 is composed of a cylinder and a round rod, the outer surface of the round rod is slidably connected to the inner wall of the cylinder, and one end of the round rod is connected to the baffle 395, and one end of the cylinder is connected to the rotating drum 26. When the rotating drum 26 rotates, the baffle 395 is driven to rotate on the thread 262 and move to one side, so that the through hole 261 is connected to the inner wall of the rotating drum 26.

[0048] The entire device is moved to the position where water needs to be collected, and the motor arranged on the limit rod 22 drives the second rotating block 25 to rotate, and synchronously drives the rotating drum 26 to rotate, and synchronously drives the circular ring 28 arranged on its outer surface to rotate. At the same time, a scraper is arranged at the end of the circular ring 28. When the circular ring 28 rotates, impurities and particulate matter around the rotating drum 26 are pushed out, so that the impurity content in the collected water is reduced, and the blockage phenomenon is reduced.

[0049] In addition, the first rotating block 24 cooperates with the rotating shaft 27 to drive the docking block 31 to rotate, and drives the positioning shaft 34 set on the docking block 31 to rotate. Since the connecting tube 39 is set at the end of the positioning shaft 34, the connecting tube 39 rotates synchronously. Since the slider 392 is in contact with the protrusion 393, the stretching rod 394 set on the slider 392 rotates, thereby driving the baffle 395 to rotate.

[0050] When the positioning shaft 34 rotates, the support rod 35 arranged on its outer surface is driven to rotate, thereby driving the rotating block 36 arranged at its end to move, so that a misalignment occurs between the rotating block 36 and the movable block 38, and then the adjustment plate 381 arranged on the movable block 38 is adjusted in angle, thereby realizing the regulation of the water flow rate.

[0051] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
