Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of environmental engineering, specifically relates to a wetland edge area bottom mud turning device. BACKGROUND

[0002] Artificial wetland is a kind of artificial construction system that imitates the function of natural wetland, and is used for treating sewage and purifying water quality. It is usually composed of aquatic plants, microorganisms, substrates and water bodies, and removes pollutants in water through the synergistic effect of physical, chemical and biological processes. It has the technical advantages of low cost, simple operation, easy maintenance and good ecological benefits.

[0003] When designing and constructing artificial wetlands, appropriate plant species and substrate materials are usually selected according to the scale of sewage treatment and the target water quality requirements. In addition to floating plants, the common submerged plants, floating plants and emergent plants in artificial wetlands need to be rooted in wetland bottom mud to obtain necessary support and nutrient support. Therefore, the soil in the planting area needs to be turned and mixed before planting to improve the soil permeability and fertility, which can effectively promote plant growth. In addition, regular turning of the bottom mud can release the nutrient salts and effectively prevent the bottom mud from hardening, which is an important work in the maintenance and management of artificial wetlands.

[0004] At present, the traditional bottom mud turning method mainly relies on manpower or simple machinery, which is low in efficiency and high in labor intensity, and it is difficult to meet the management needs of large-scale artificial wetland areas.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0026] See also Figure 1 A preferred embodiment of a bottom mud turning device for a wetland edge area is provided, which is used to improve the bottom mud environment in the edge area of ​​an artificial wetland to promote plant growth and maintain ecological balance.

[0027] In this embodiment, the device includes a frame frame 1 as a structural support. A welded frame is formed at the bottom of the frame frame 1, to which a planar floating plate 18 is welded. This planar floating plate 18 increases the contact area with the wetland's edge mud, thereby reducing the pressure per unit area, allowing the entire device to float stably on the mud surface. Furthermore, both sides of the planar floating plate 18 are raised to form raised edges 10. These raised edges 10 serve as guide structures, formed on the forward and backward sides of the planar floating plate 18, ensuring stability and directionality during movement of the device at the wetland's edge.

[0028] In another embodiment, the device can be provided with a towing frame at the front end of the frame support 1, which is connected to a power machine assembly, so that the device can be towed and moved by the power machine. In addition, a counterweight box can be provided on the frame support 1, and the counterweight box can be filled with counterweights of different weights to ensure the stability of the device when working in the wetland edge area, preventing the center of gravity of the device from shifting during movement and operation, resulting in tipping or difficulty in operation.

[0029] In this embodiment, the device also includes functional components for tamping the bottom mud, comprising a lifting base 6 and a tamping assembly. Specifically, a through-hole extending vertically through the center of the planar floating plate 18 is provided. A guide tube 7 is welded to the surface of the planar floating plate 18 corresponding to the through-hole. The guide tube 7 has an inwardly tapered upper portion and a cylindrical volume chamber 12 formed below.

[0030] The guide cylinder 7 is fitted with a lifting seat 6 at the inner neck position. The upper portion of the lifting seat 6 is assembled and connected to an assembled coupling 5. This assembled coupling 5 has a dual-output, dual-input structure, with one corresponding input end and one corresponding output end respectively assembled and connected to the lifting seat drive motor 19 and the main body of the lifting seat 6, thereby controlling the lifting of the lifting seat 6 via the lifting seat drive motor 19. To improve the stability of the lifting seat 6 in the inner neck position of the guide cylinder 7, a plurality of guide grooves are uniformly formed on the inner annular surface of the inner neck of the guide cylinder 7. The lifting seat 6 is embedded in the guide grooves and guided by the guide grooves to ensure stable lifting of the lifting seat 6 within the guide cylinder 7.

[0031] The lifting seat 6 is equipped with a shaft 16, which can be raised and lowered along with the lifting seat 6; at the same time, the shaft 16 itself can rotate and drive the tamping assembly assembled at the lower end of the shaft 16 to rotate; correspondingly, the upper end of the shaft 16 and the shaft drive motor 2 for driving the shaft 16 to rotate are assembled on the other pair of input and output ends of the assembled coupling 5, so that when the shaft drive motor 2 is connected to the assembled coupling 5 through the motor output shaft 4, the shaft 16 can be driven to rotate through the action of the shaft drive motor 2.

[0032] In order to optimize the use effect, the shaft drive motor 2 and the lifting seat drive motor 19 in this embodiment both adopt stepless motors. The shaft drive motor 2 can provide smooth and continuous rotational power to ensure that the tamping component is evenly and effectively turned in the wetland bottom mud, while the lifting seat drive motor 19 ensures that the tamping component can operate effectively in mud layers of different depths, while avoiding excessive disturbance of the bottom mud and protecting the ecological environment of the wetland.

[0033] In different embodiments, the tamping assembly can be configured in two ways:

[0034] A kind of Figure 1 The illustrated embodiment focuses on the effectiveness and efficiency of tamping the bottom mud. In this embodiment, the tamping assembly includes a sleeve 14 and a tamping arm 15. The sleeve 14 is fixed to the lower end of a shaft 16 as an assembly structure. The tamping arm 15 is detachably connected to the sleeve 14 via an arm shaft, which rotates with the rotation of the shaft 16. The entire tamping arm 15 is tilted on the sleeve 14 at an angle of 45 to 60 degrees. A plurality of tamping teeth 13 are evenly distributed on the arm of the tamping arm 15. These tamping teeth 13 are arranged in a spiral pattern on the arm of the tamping arm 15. During the rotation of the sleeve 14, the tamping arm 15 can effectively stir the bottom mud, promoting its loosening and mixing.

[0035] In another embodiment, the combination of the tamping arms 15 and the tamping teeth 13 can be directly replaced with a plurality of spiral tamping blades formed on the outer surface of the sleeve 14, thereby achieving easier assembly and maintenance. In this embodiment, the spiral tamping blades are directly formed on the outer surface of the sleeve 14. These blades simplify the assembly process of the tamping assembly, reduce maintenance costs, and also reduce the possibility of failures caused by improper assembly. When in use, they can also rotate with the sleeve 14 to stir the bottom mud, achieving a similar effect as the tamping arms 15 and tamping teeth 13.

[0036] In this embodiment, the tamping assembly switches between the standby position and the working position by lifting and lowering the lifting seat 6. When in standby mode, the entire tamping assembly is stored in the cylindrical volume cavity 12 to protect the tamping teeth 13 from damage.

[0037] Additionally, a motor assembly bracket 3 with a buffer structure and a stabilizing bracket 8 with legs 9 are mounted on either side of the frame bracket 1. The motor assembly bracket 3 utilizes a cushioning rubber pad 11 as a buffer structure and is used to mount the drive motor 2. The stabilizing bracket 8, on the other hand, is used to mount the lifter drive motor 19. Rubber pads are also provided on the bracket body to provide a cushioning effect, ensuring the stability of the lifter drive motor 19 and reducing impacts on the equipment during movement and operation at the edge of wetlands. To further enhance the adaptability and stability of the device, the legs 9 of the stabilizing bracket 8 are designed to be height-adjustable.

[0038] In addition, in this embodiment, to further protect aquatic plants, the device is equipped with two side baffles 17 below the flat floating plate 18. These two side baffles 17 are located on either side of the tamping assembly and are oriented parallel to the forward direction of the device. The side baffles 17 have an inward-sloping guide slope on the forward side to minimize interference with established aquatic plants.

[0039] In summary, the present invention's wetland marginal sediment stirring device, through a series of structural designs, effectively stirs the sediment at the edge of constructed wetlands while avoiding damage to aquatic plants and maintaining the wetland's ecological balance. The device is easy to operate, low-cost, and suitable for the management of large-scale constructed wetland areas, possessing significant practical value and promising prospects for widespread adoption.

Those skilled in the art should understand that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. Furthermore, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications, and / or variations to the present invention, all of which equivalent forms fall within the scope of protection defined by the appended claims.
