Abstract

This utility model discloses a subsurface flow constructed wetland blockage monitoring device, relating to the field of wetland blockage monitoring technology. The device includes a monitoring tube and a soil-brick ring-cutting mechanism. The soil-brick ring-cutting mechanism consists of a ring-cutting execution part, a driving part, and a limiting part. The ring-cutting execution part includes a movable ring and several shovels. Through the design of the soil-brick ring-cutting mechanism, the monitoring tube is directly placed on the planting soil layer, allowing the shovels to penetrate into the planting soil layer.

This method simplifies the soil treatment process before monitoring tube insertion to a certain extent. The use of shovels to cut a ring provides temporary protection for the planting soil layer, reducing the tediousness of manually removing the soil layer and excessive damage to vegetation.

Description

Technical Field

[0001] This utility model relates to the field of wetland blockage monitoring technology, specifically to a device for monitoring blockage in subsurface flow constructed wetlands. Background Technology

[0002] Subsurface flow constructed wetlands are widely used in wastewater treatment plants for effluent treatment and reclaimed water reuse due to their excellent pollutant removal capabilities. However, they are prone to clogging due to physical, chemical, and biological factors during long-term operation, affecting effluent quality and even breeding mosquitoes and flies, thus damaging the ecological appearance. Existing clogging control methods have limitations; the former cannot meet the requirements of uninterrupted operation, and the latter is technically immature. Therefore, early detection of clogging and targeted operation and maintenance are crucial.

[0003] The patent publication number CN219608088U, entitled "A Clogging Monitoring Device for Subsurface Flow Artificial Wetland", innovatively proposes a method to assess clogging by injecting water into a monitoring pipe and controlling the water flow infiltration using an opening and closing disc, and using water level-time data. This method has advantages such as not interfering with wetland operation and providing intuitive and reliable data.

[0004] However, in practice, the planting soil layer needs to be manually removed before the monitoring tube is inserted. For wetlands that are already in operation, the planting soil layer and the filler layer are tightly bonded. Removing the soil layer can easily damage the vegetation and affect the wetland ecosystem. This is especially true when there are many monitoring points and a large wetland area, where the efficiency and ecological costs are significant issues. Utility Model Content

[0005] To address the aforementioned technical problems, a device for monitoring blockages in subsurface flow constructed wetlands is provided, which solves the problems existing in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a monitoring device for blockage in subsurface flow artificial wetlands, the device comprising a monitoring tube and a circumferential cutting mechanism for easily removing the planting soil layer at the monitoring point;

[0007] The adobe ring-cutting mechanism consists of a ring-cutting execution part, a driving part, and a limiting part;

[0008] The ring-cutting actuator includes a movable ring rotatably sleeved on the bottom of the outer wall of the monitoring tube, and several circumferentially distributed scrapers that are detachably installed on the bottom surface of the movable ring.

[0009] Preferably, the drive unit includes a movable seat that is rotatably mounted on the top of the outer wall of the monitoring tube via a bearing, and a handle is connected between the movable seat and the movable ring.

[0010] Preferably, the limiting part includes a limiting ring groove surrounding the outer wall of the monitoring tube, and a plurality of limiting screws distributed circumferentially and threaded through the movable ring. One end of the limiting screw is rotatably fitted with a ball, which can be adapted to roll within the limiting ring groove.

[0011] Preferably, one end of the handle is fixedly connected to the top surface of the movable ring, and the other end of the handle is fixed with an assembly block, which is detachably connected to the movable seat by screws.

[0012] Preferably, the handle is convex, and a clearance space is formed between the handle and the outer wall of the monitoring tube.

[0013] Preferably, the top of the shovel is fixed with a mounting base, and the bottom surface of the movable ring is provided with an insertion port that is compatible with the mounting base.

[0014] Preferably, the outer side wall of the movable ring is threaded with a mounting screw along a radial thread, the mounting screw can be retracted into the socket, and the mounting base is provided with a positioning hole corresponding to the mounting screw.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] By using a soil-brick ring-cutting mechanism, the monitoring tube is placed directly on the planting soil layer, allowing the shovel blade to penetrate into the soil. The rotating part then uses the shovel to cut around the monitoring tube, forming a soil ring that matches the tube. The soil ring is then gently removed to facilitate manual insertion of the monitoring tube. After the water injection monitoring process is completed, the soil ring is backfilled. This method simplifies the soil preparation process before monitoring tube insertion, providing temporary protection to the planting soil layer by using a shovel to create a ring. This reduces the tediousness of manually removing the soil and excessive damage to vegetation, minimizing the impact on wetland ecosystems and optimizing the pre-monitoring preparation stage.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figure 1 As shown, a device for monitoring blockage in a subsurface flow constructed wetland includes a monitoring tube 1;

[0025] Referring to the patent publication number CN219608088U, “A Subsurface Flow Artificial Wetland Blockage Monitoring Device”, in the existing wetland blockage monitoring system, a louvered opening and closing disc for controlling the opening and closing of the internal channel is set more than 30cm from the bottom inside the monitoring tube 1 (see diagram not shown). The monitoring tube is equipped with a control rod for controlling the rotation of the opening and closing flaps to achieve opening and closing (see diagram not shown). The above are existing known technical features, which will not be elaborated in this case.

[0026] When using this device, the planting soil layer needs to be removed, and the monitoring tube 1 should be vertically inserted into the filler layer to a depth of 30cm. The operation procedure is as follows: first, close the opening and closing disc, and inject water into the monitoring tube to leave a certain amount of water in the area above the opening and closing disc; then open the opening and closing disc, and the water in the tube will seep downwards through the disc. By using the water level-time data changes, the blockage status at the corresponding point can be accurately assessed. This monitoring mode does not interfere with the normal operation of the constructed wetland, and can obtain blockage parameters that are closer to the actual working conditions; moreover, it can measure point by point, is low in cost, highly accurate, does not rely on complex models, and the data directly reflects the actual blockage status. The testing is convenient and efficient, and the operation is simple and easy to implement, effectively adapting to the blockage monitoring needs of subsurface flow constructed wetlands.

[0027] However, in practice, the planting soil layer needs to be manually removed before the monitoring tube 1 can be inserted. For wetlands that are already in operation, the planting soil layer and the filler layer are tightly bonded. Removing the soil layer can easily damage the vegetation and affect the wetland ecology. This is especially true when there are many monitoring points and a large wetland area, where the efficiency and ecological costs are prominent.

[0028] Therefore, referring to Figure 1 and Figure 4 As shown, it is worth noting that the device also includes a circumferential cutting mechanism for easily removing the planting soil layer at the monitoring point.

[0029] The adobe ring-cutting mechanism mainly consists of a ring-cutting actuator and a driving mechanism;

[0030] The ring-cutting actuator includes a movable ring 2 that is rotatably sleeved on the bottom of the outer wall of the monitoring tube 1, and several circumferentially distributed scrapers 3 that are detachably installed on the bottom surface of the movable ring 2;

[0031] By using a soil-brick ring-cutting mechanism, the monitoring tube 1 is placed directly on the planting soil layer, allowing the shovel 3 to penetrate into the soil. The rotating part then uses the shovel 3 to cut around the monitoring tube 1, forming a soil ring that matches the tube. The soil ring is then gently removed to facilitate manual insertion of the monitoring tube 1. After the water injection monitoring process is completed, the soil ring is backfilled. This method simplifies the soil preparation process before monitoring tube insertion, providing temporary protection for the planting soil layer by using a shovel to create a ring. This reduces the tediousness of manually removing the soil and excessive damage to vegetation, minimizing the impact on wetland ecosystems and optimizing the pre-monitoring preparation stage.

[0032] Furthermore, referring to Figure 3 As shown, it is worth noting that the top of the shovel 3 is fixed with a mounting base 9, and the bottom surface of the movable ring 2 is provided with an insertion port that is compatible with the mounting base 9.

[0033] The outer side wall of the movable ring 2 is threaded with a mounting screw 10 along the radial direction. The mounting screw 10 can be retracted into the socket. The mounting base 9 is provided with a positioning hole corresponding to the mounting screw 10.

[0034] With the mounting base 9 and mounting screw 10, the blade 3 can be quickly positioned by the mounting base 9 and the socket, and then a stable connection is achieved by the mounting screw 10 locking with the positioning hole. When the blade 3 wears down due to long-term cutting or needs to be replaced with a different blade type according to the soil type, it can be disassembled and replaced simply by loosening the mounting screw 10. The operation is convenient and the connection is reliable, adapting to the cutting needs of different wetland planting soil layers and extending the overall service life of the device.

[0035] Furthermore, referring to Figure 1 and Figure 2 As shown, it is worth noting that the drive unit includes a movable seat 3 that is rotatably mounted on the top of the outer wall of the monitoring tube 1 via a bearing, and a lever 5 is connected between the movable seat 3 and the movable ring 2.

[0036] With the drive mechanism in place, when the operator holds the lever 5 and applies force, the movable seat 3 rotates flexibly around the monitoring tube 1. The torque is smoothly transmitted to the movable ring 2 through the lever 5, which drives the movable ring 2 and the bottom blade 3 to move in a circular motion around the monitoring tube 1 in sync.

[0037] Furthermore, referring to Figure 1 As shown, it is worth noting that the handlebar 5 is convex in shape;

[0038] This convex structure creates a clearance space between the lever 5 and the outer wall of the monitoring tube 1, preventing interference or collision between the lever and the control rod during rotation.

[0039] Furthermore, referring to Figure 2 As shown, it is worth noting that one end of the handle 5 is fixed to the top surface of the movable ring 2, and the other end of the handle 5 is fixed with an assembly block 11. The assembly block 11 and the movable seat 3 are detachably connected by screws.

[0040] The detachable assembly block 11 and movable seat 3 allow the handle 5, movable ring 2 and shovel 3 to be separated from the movable seat 3 as a whole. This allows the whole assembly to be removed from the monitoring tube 1 after the planting layer soil is cut, so that the monitoring tube 1 can be inserted into the filler layer separately and avoid movement interference.

[0041] Meanwhile, this separation structure enables the device to be "functionally modularly disassembled". The cutting stage assembles complete components to ensure the ring cutting function, while the monitoring stage retains only the monitoring tube 1 and necessary parts, which significantly reduces the weight of a single component. This not only makes it easier for people to carry the monitoring tube 1 to complete the insertion operation and reduces physical burden, but also allows the device to be disassembled and stored during transportation or storage, reducing space occupation and improving portability and practicality.

[0042] Furthermore, referring to Figure 2 and Figure 3 As shown, it is worth noting that the adobe ring cutting mechanism also includes a limiting part for enhancing the stability of the ring cutting actuator during operation;

[0043] The limiting part includes a limiting ring groove 8 that surrounds the outer wall of the monitoring tube 1, and a plurality of limiting screws 6 that are distributed circumferentially and threaded through the movable ring 2. One end of the limiting screw 6 is rotatably embedded with a ball 7, which can be adapted to roll in the limiting ring groove 8.

[0044] By setting the limiting part, during assembly, the contact tightness between the ball 7 and the limiting ring groove 8 is adjusted by rotating the limiting screw 6, so that the ball 7 is tightly locked into the limiting ring groove 8. When the movable ring 2 drives the shovel 3 to rotate around the monitoring tube 1, the ball 7 rolls synchronously along the limiting ring groove 8. The circumferential limiting effect of the limiting ring groove 8 on the ball 7 restricts the radial swing and axial movement of the movable ring 2, ensuring that the ring cutting actuator always makes a stable circular motion around the axis of the monitoring tube 1, avoiding the deviation of the cutting trajectory caused by uneven soil resistance, and further improving the forming accuracy of the adobe ring and the smoothness of the cutting process.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
