Description

Technical Field

[0001] The utility model relates to the field of river channel management, in particular to a suspension device used for river channel management. Background Art

[0002] Moss is caused by filamentous algae, including 11 categories such as Spirogyra, Spirogyra, Hydrodiplophyta, and Diplophyta. The growth of moss is affected by environmental factors such as temperature, light, salinity, and pH, among which light is the primary factor that promotes the growth of Spirogyra cells and their metabolic activity. Most of the mosses in the river are caused by Spirogyra of the filamentous algae Spirogyra. The growth of Spirogyra is suitable for thin and shallow water bodies with high light intensity and high temperature. When the conditions are right, the strong reproduction and spread of moss "algae bloom" will cause harm and seriously damage the balance of the aquatic ecosystem. The large-scale existence of filamentous algae in the river will affect the growth of other aquatic organisms through nutrient competition, algal entanglement, allelopathic effects, and light shielding. After the death, it will float densely on the water surface, showing yellow-green, yellow or black with bubbles, the water color will turn white, the dissolved oxygen in the water will decrease, and toxic and harmful gases will be emitted, destroying the landscape effect of the water body.

[0003] In the face of the harm caused by moss, commonly used treatment methods include using composite fillers for water purification. However, conventional spraying fillers are expensive, direct spraying requires multiple tasks, and is labor-intensive. The work efficiency is low and cannot meet the needs of river management.

[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figures 1 to 3 As shown, it is a schematic diagram of the structure of the suspension device for river management provided by the utility model. The suspension device for river management includes an ecological screen 10 and a plurality of ecological balls 20 filled in the ecological screen 10. It can be imagined that the suspension device for river management also includes other functional modules such as anchor cables for positioning, buoys for easy marking, etc., which are well known to those skilled in the art and will not be described one by one here.

[0018] The ecological screen 10 includes a plurality of floating barriers 11, a group of traction ropes 12 arranged at both ends of the floating barriers 11, a plurality of close-mesh sinking nets 13 connected to the floating barriers 11, a plurality of counterweights 14 arranged on the close-mesh sinking nets 13, and a group of rod-type movable joints 15 arranged between every two floating barriers 11.

[0019] The outer layer of the floating barrier 11 is made of high-density polyethylene, and the interior is wrapped with foam plastic to give it extremely strong buoyancy. The traction rope 12 is arranged at both ends of the floating barrier 11 and is symmetrically arranged, and has a positioning and aiming function to accurately cover the water treatment range. The dense mesh sinking net 13 is connected to the outer layer of the floating barrier 11. This net is closed on three sides, and the depth and aperture can be adjusted as needed to fully recover the eco-ball. The counterweight 14 is arranged at the lower part of the dense mesh sinking net 13 away from the floating barrier 11 to ensure the straightness of the sinking net in the water. The rod-type movable joint 15 is placed between the two floating barriers 11, and the direction can be adjusted freely, and the rigidity of the ecological screen is increased to facilitate the recovery of the eco-ball 20.

[0020] The eco-ball 20 includes two interlocking low-density upper hemispheres 21 and high-density lower hemispheres 22, a core balloon 23 arranged in the low-density upper hemisphere 21, a plurality of flower holes 24 opened on the high-density lower hemisphere 22, a composite filler 25 filled in the high-density lower hemisphere 22, and a plurality of connecting buckles 26 arranged at the connection between the low-density upper hemisphere 21 and the high-density lower hemisphere 22.

[0021] The low-density upper hemisphere 21 and the high-density lower hemisphere 22 are both made of polyethylene, and the density of the high-density lower hemisphere is 0.94-0.965 g / cm 3 The density of the low-density upper hemisphere is 0.91-0.94 g / cm 3 . The low-density upper hemisphere 21 is fully enclosed, without holes all over, and carbon black modifying materials are added to make the whole body appear black, so as to effectively block the sunlight and dissipate heat faster at night. The high-density lower hemisphere 22 is white all over, or decorated in blue, green, etc., to distinguish it from the low-density upper hemisphere 21. Due to the density difference between the low-density upper hemisphere 21 and the high-density lower hemisphere 22, the low-density upper hemisphere 21 is easier to float on the surface, and the two are centrally symmetrical with the connection as the axis. A baffle occupying half of the circumference is provided at the opening of the low-density upper hemisphere 21 and the high-density lower hemisphere 22, and they are misaligned and attached when the low-density upper hemisphere 21 and the high-density lower hemisphere 22 are buckled together, so that the space between the low-density upper hemisphere 21 and the high-density lower hemisphere 22 can be separated from each other when the two are buckled together, and will not be affected. At the same time, it is convenient to take out the core balloon 23 and the composite filler 25 and replace them.

[0022] The core balloon 23 is arranged inside the low-density upper hemisphere 21 to adjust the buoyancy of the eco-sphere 20. At the same time, it should be noted that the upper hemisphere should not be filled up during inflation to prevent explosion due to heat transfer.

[0023] The flower holes 24 are arranged at the bottom of the high-density lower hemisphere 22 away from the low-density upper hemisphere 21, and are densely distributed within 1 / 3 of the bottom, and adjacent flower holes 24 are spaced apart from each other to facilitate the placement of fillers and immersion of the fillers in the water body. The flower holes 24 are arranged in a plum blossom shape. It should be noted that when the flower holes 24 are arranged, the structural strength and quality of the high-density lower hemisphere 22 will not be greatly reduced.

[0024] The composite filler 25 is a common technology widely used in the field of sewage treatment technology and should be well known to those skilled in the art, so it is only briefly described here. It is made into granules and placed in the high-density lower hemisphere 22, so that the filler slowly dissolves in the river channel and is evenly distributed by means of the low-density upper hemisphere 21 on the water surface and the high-density lower hemisphere 22 in the water.

[0025] The connecting buckles 26 are arranged in groups of two on the low-density upper hemisphere 21 and the high-density lower hemisphere 22, respectively. The two connecting buckles 26 in the same group are attached to each other and passed through by a buckle pin or fastener, and each eco-ball 20 is provided with at least one pair of connecting buckles 26 on the diameter of the eco-ball 20, so as to fix them when the two are buckled together.

[0026] Compared with the prior art, the utility model provides a suspension device for river management, which mainly includes the eco-screen 10 and the eco-ball 20. The eco-screen 10 provides a water treatment boundary by setting the floating barrier 11, and the eco-ball 20 has a shading effect and can provide a filler slow-release effect. The two work together to make it easy to operate and recycle the eco-ball 20, and the effect is significant. The eco-ball 20 uses the low-density upper hemisphere 21 and the high-density lower hemisphere 22 of different densities, and the filler is placed in the high-density lower hemisphere 22 with holes, so that when the ball floats on the water surface, the filler is immersed in the water body and slowly dissolved in the river, which helps to increase the use time of the filler and ensure the stability of water purification.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
