Description

Technical Field

[0001] This utility model relates to the field of multifunctional ecological dam technology, specifically a multifunctional ecological dam for purifying water quality after paddy field drainage. Background Technology

[0002] Agricultural runoff refers to wastewater and liquid waste discharged during agricultural production processes such as crop cultivation, livestock feeding, and food processing. This runoff may contain harmful substances such as pesticide and fertilizer residues and pathogenic microorganisms. If discharged directly into the environment without proper treatment, it will pollute water bodies and affect the ecological environment and human health. Therefore, it is necessary to purify the runoff to ensure that the water flowing out of paddy fields meets the required standards.

[0003] When existing ecological dams are in use, the sand and gravel filling the inner side of the dam tend to clump together after filtering water for a long time, which affects the filtration effect. The dam body does not have the function of stirring the sand and gravel, so the clumps of sand and gravel affect the water purification effect. At the same time, when existing ecological dams are in use, there is no effective fixed connection between the dam body and the floating plate, which makes the floating plate easy to move and affect the purification effect of the water area around the dam. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a multifunctional ecological dam for purifying the water quality of paddy field drainage. By setting a No. 1 motor, a No. 2 motor and a stirring shaft, the No. 1 motor and the No. 2 motor can drive the stirring shaft to rotate, thereby stirring the pebble layer and the fine sand layer, breaking up the clumps of sand and gravel, ensuring the filtration effect of the sand and gravel layer on the water, and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional ecological dam for purifying water quality after paddy field drainage, comprising a dam body box, a No. 1 motor installed on the upper side of the dam body box, a No. 2 motor installed on the inclined surface of one side of the dam body box, both the No. 1 and No. 2 motors having their output ends connected to a stirring shaft, a filter screen installed on the inclined surface of the other side of the dam body box, a floating disc provided on the upper side of the filter screen, and straw ropes installed at equal intervals on the lower side of the floating disc.

[0006] Furthermore, the lower side of the filter screen is filled with gravel, and pebbles are arranged on the lower side of the gravel.

[0007] Furthermore, gravel is provided on the lower side of the pebble, and fine sand is provided on the lower side of the gravel.

[0008] Furthermore, a filter plate is provided between the gravel, the pebbles, the crushed stone and the fine sand, and the stirring shaft is respectively embedded in the pebbles, the crushed stone and the fine sand.

[0009] Furthermore, baffles are installed at both ends of the dam body box, and a concrete retaining wall is provided on one side of the baffle.

[0010] Furthermore, a retaining block is vertically installed on the side of the concrete retaining wall away from the baffle, and a water outlet is provided on the side of the dam body below the No. 2 motor.

[0011] Furthermore, the retaining block and the concrete retaining wall are an integral structure, and the baffle is fixedly connected to the dam body box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model, through the setting of a No. 1 motor, a No. 2 motor and a stirring shaft, enables the No. 1 motor and the No. 2 motor to drive the stirring shaft to rotate, thereby stirring the pebble layer and the fine sand layer, breaking up the clumps of sand and gravel, and ensuring the filtration effect of the sand and gravel layer on the water.

[0014] This utility model uses a floating disc, a filter screen, and straw ropes to fix the floating disc to the filter screen. This allows the floating disc to be placed on the upper side of the filter screen, so that the aquatic plants on the floating disc can purify the water around the filter screen inlet, ensuring the water purification effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This embodiment provides a technical solution: a multifunctional ecological dam for purifying the water quality of paddy field drainage, including a dam body box 1. A first motor 13 is installed on the upper side of the dam body box 1, and a second motor 14 is installed on the inclined surface of one side of the dam body box 1. The output ends of the first motor 13 and the second motor 14 are both connected to a stirring shaft 15. A filter screen 6 is installed on the inclined surface of the other side of the dam body box 1. A floating plate 5 is set on the upper side of the filter screen 6, and straw ropes 16 are installed at equal intervals on the lower side of the floating plate 5.

[0021] like Figure 1-3 As shown, the receding water gathers at the front of the dam box 1. The water enters the inner side of the dam box 1 through the filter screen 6. Gravel 8, pebbles 9, crushed stone 10, and fine sand 11 can filter and purify the water. Aquatic plants are planted on the floating plate 5, which can purify the water. Straw rope 6 can connect and fix the floating plate 5 to the filter screen 6, so that the aquatic plants on the floating plate 5 can purify the water around the filter screen 6 opening. The concrete retaining wall 2 and retaining block 7 can stably support the baffle 4, ensuring that the dam box 1 is stably supported. The purified and filtered water flows out through the outlet 3. When the pebbles 9 and fine sand 11 clump together, the first motor 13 and the second motor 14 can drive the stirring shaft 15 to rotate, so that the stirring shaft 15 can stir and mix the pebbles 9 and fine sand 11, preventing the pebbles 9 and fine sand 11 from clumping together and ensuring the filtration effect.

[0022] The lower side of the filter screen 6 is filled with gravel 8, and pebbles 9 are placed on the lower side of the gravel 8.

[0023] Pebbles 9 are placed at an angle below gravel 10, and gravel 10 is placed at an angle below fine sand 11.

[0024] A filter plate 12 is installed between gravel 8, pebble 9, crushed stone 10 and fine sand 11, and a stirring shaft 15 is buried in pebble 9, crushed stone 10 and fine sand 11 respectively.

[0025] The dam body box 1 is equipped with baffles 4 at both ends, and a concrete retaining wall 2 is set on one side of the baffles 4.

[0026] A retaining block 7 is vertically installed on the side of the concrete retaining wall 2 away from the baffle 4, and a water outlet 3 is installed on the side of the dam body below the No. 2 motor 14.

[0027] The retaining block 7 and the concrete retaining wall 2 are an integral structure, and the baffle 4 is fixedly connected to the dam body box 1.

[0028] The working principle of the multifunctional ecological dam for purifying paddy field runoff water provided by this utility model is as follows: Figures 1-3As shown, the receding water gathers at the front of the dam box 1. The water enters the inner side of the dam box 1 through the filter screen 6. Gravel 8, pebbles 9, crushed stone 10, and fine sand 11 can filter and purify the water. Aquatic plants are planted on the floating plate 5, which can purify the water. Straw rope 6 can connect and fix the floating plate 5 to the filter screen 6, so that the aquatic plants on the floating plate 5 can purify the water around the filter screen 6 opening. The concrete retaining wall 2 and retaining block 7 can stably support the baffle 4, ensuring that the dam box 1 is stably supported. The purified and filtered water flows out through the outlet 3. When the pebbles 9 and fine sand 11 clump together, the first motor 13 and the second motor 14 can drive the stirring shaft 15 to rotate, so that the stirring shaft 15 can stir and mix the pebbles 9 and fine sand 11, preventing the pebbles 9 and fine sand 11 from clumping together and ensuring the filtration effect.
