Description

Technical Field

[0001] This invention relates to the field of river water treatment technology, and in particular to a river water treatment device. Background Technology

[0002] Watershed pollution is caused by harmful chemicals that reduce or eliminate the usability of water, polluting the environment. Currently, aquatic plants are often used to treat river water pollution. Generally, aquatic plants are planted in special planting pots, which are then placed on a floating frame. The plant roots are immersed in the polluted water, and the water quality is gradually purified by the absorption and adsorption of the plant roots. However, the water in the river is highly mobile, and the flowing water creates a continuous and strong water force impact on the bottom of the planting pot. This impact damages the roots of the aquatic plants, affecting their normal growth and metabolic functions, weakening their ability to absorb and degrade pollutants, and thus reducing the effectiveness of wastewater treatment. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies where flowing water exerts a continuous and strong hydraulic impact on the bottom of planting pots, causing root damage and thus reducing the effectiveness of wastewater treatment. Therefore, this invention proposes a river water quality treatment device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A river water quality treatment device is designed, including a floating frame. The bottom end of the floating frame is provided with a floating ring. The upper end of the floating frame has a plurality of grooves evenly spaced along its length, and each groove is provided with a planting pot. The floating frame is provided with an adaptive anchoring mechanism for fixation. The bottom end of the floating frame is connected to an open frame. The open frame is provided with a filter screen for filtering debris. One side of the inner wall of the open frame is provided with a first buffer plate, and the other side of the inner wall of the open frame is provided with a second buffer plate. The first buffer plate and the second buffer plate are staggered. The open frame is provided with a perforated plate for buffering water flow.

[0006] Preferably, the adaptive anchoring mechanism includes two symmetrically arranged insert rods, both of which are slidably inserted into the floating frame. The floating frame is fixedly connected to a first connecting rod on each opposite side. One end of each first connecting rod is fixedly connected to a fixing ring. Each insert rod passes through a corresponding fixing ring. Each fixing ring has a plurality of rollers evenly spaced along the axis on its inner ring wall. Each roller makes rolling contact with the outer wall of the corresponding insert rod.

[0007] Preferably, a baffle is provided between the upper ends of the two insertion rods, and a transparent plate is provided on the baffle.

[0008] Preferably, it further includes a liquid exchange mechanism, which includes an open liquid guide frame, one end of which is connected to an open frame, the inlet end of which is located at the upper end of the second buffer plate, a rotating blade rotatably disposed inside the open liquid guide frame, one end of which is fixedly connected to a connecting shaft, a housing is installed on one side of the open liquid guide frame, one end of the connecting shaft extends outside the open frame and is inserted into the housing, a drive impeller is provided at one end of the connecting shaft, a water inlet is opened on one side of the housing, and a water outlet is opened at the bottom of the housing.

[0009] Preferably, the height of the inlet is higher than the height of the outlet.

[0010] Preferably, the bottom end of the open liquid guide frame is connected to a base frame, and the water inlet is provided with a filter frame for filtering impurities.

[0011] Preferably, it further includes a water flow impact transformation mechanism, which includes an arc-shaped plate fixedly connected to the open liquid guide frame. The arc-shaped plate is located above the rotating blade. A first strip-shaped hole is opened at the upper end of the arc-shaped plate. Guide plates are fixedly connected to both sides of the first strip-shaped hole. One end of each guide plate is fixedly connected to the inner wall of the open liquid guide frame.

[0012] Preferably, a partition is installed on the inner wall of the open liquid guide frame, and a narrow channel is provided between the partition and the open liquid guide frame.

[0013] Preferably, a plurality of second connecting rods are fixedly connected to the upper end of the perforated plate, and the same third buffer plate is fixedly connected to the upper end of the plurality of second connecting rods. The third buffer plate is located above the open liquid guide frame, and a second strip hole is provided on both sides of the upper end of the third buffer plate.

[0014] Preferably, each of the second strip-shaped holes is inclined toward the inner wall of the open frame.

[0015] The river water quality treatment device proposed in this invention has the following advantages:

[0016] The water flow is initially buffered by the first and second buffer plates, and then further buffered by the perforated plate. This consumes the kinetic energy of the water flow and reduces the impact intensity when the water flow comes into contact with the bottom of the planting pot. This prevents the water flow from eroding and damaging the plant roots, thus improving the treatment effect of wastewater. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1: Refer to Figure 1-4 A river water quality treatment device includes a floating frame 1, a floating ring 2 at the bottom end of the floating frame 1, and a plurality of grooves 3 evenly spaced along the length direction at the top end of the floating frame 1. Each groove 3 contains a planting pot 4. The floating frame 1 is provided with an adaptive anchoring mechanism 5 for fixing. The bottom end of the floating frame 1 is connected to an open frame 6. The open frame 6 is provided with a filter screen 7 for filtering debris. One side of the inner wall of the open frame 6 is provided with a first buffer plate 8, and the other side of the inner wall of the open frame 6 is provided with a second buffer plate 9. The first buffer plate 8 and the second buffer plate 9 are staggered. The open frame 6 is provided with a perforated plate 10 for buffering water flow.

[0029] Reference Figure 1 The adaptive anchoring mechanism 5 includes two symmetrically arranged insert rods 51, both of which are slidably inserted into the floating frame 1. The floating frame 1 is fixedly connected to the opposite sides of the first connecting rod 52. One end of each first connecting rod 52 is fixedly connected to a fixing ring 53. Each insert rod 51 passes through the corresponding fixing ring 53. The inner ring wall of each fixing ring 53 is provided with several rollers 54 at equal intervals along the axis. Each roller 54 rolls in contact with the outer wall of the corresponding insert rod 51. A baffle 55 is provided between the upper ends of the two insert rods 51. A transparent plate 56 is provided on the baffle 55.

[0030] Working principle:

[0031] The floating frame 1 floats on the water surface via the floating ring 2. Two rods 51 are passed through the fixing ring 53 and inserted into the riverbed soil. The floating ring 2 allows the device to automatically adjust its height according to the water level. After the floating frame 1 moves, it drives the first connecting rod 52 to move in the vertical direction. The first connecting rod 52 drives the fixing ring 53 to move. The fixing ring 53 rolls with the rods 51 through the roller 54, reducing the friction between the fixing ring 53 and the rods 51. This ensures that the open frame 6 is always at the effective working water depth, without the need for frequent manual adjustments.

[0032] Aquatic plants are planted in the planting pot 4. The planting pot 4 is placed into the groove hole 3. When water flows into the open frame 6, the filter screen 7 filters out large particles of debris in the water to prevent debris from clogging the inside of the open frame 6. As the water continues to flow upward, it hits the staggered first buffer plate 8 and second buffer plate 9 in sequence. The first buffer plate 8 and the second buffer plate 9 work together to gradually buffer the water flow, reducing the flow velocity of the water in the open frame 6. After the water flow is slowed down by the first buffer plate 8 and the second buffer plate 9, it comes into contact with the perforated plate 10. 10. The water flow is slowed down and evened out again. The water flow passing through the perforated plate 10 passes through the planting pot 4 and comes into contact with the aquatic plants. The roots of the aquatic plants absorb the nitrogen, phosphorus and other nutrients in the wastewater, thus treating the wastewater. The first buffer plate 8 and the second buffer plate 9 provide initial buffering for the water flow, and the perforated plate 10 provides secondary buffering for the water flow, consuming the kinetic energy of the water flow and reducing the impact intensity when the water flow comes into contact with the bottom of the planting pot 4. This prevents the water flow from scouring and damaging the plant roots, thus improving the treatment effect of the wastewater.

[0033] Example 2: When wastewater passes through the perforated plate 10 and comes into contact with the aquatic plants in the planting pot 4, some debris tends to accumulate between the upper end of the perforated plate 10 and the planting pot 4. Simultaneously, the wastewater exchange rate between the upper end of the perforated plate 10 and the bottom of the planting pot 4 is slow, easily forming a stagnant water zone and reducing the wastewater treatment effect. (Refer to...) Figure 5-9 As another preferred embodiment of the present invention, the difference from embodiment 1 is that it further includes a liquid exchange mechanism 11. The liquid exchange mechanism 11 includes an open liquid guide frame 111, one end of which is connected to an open frame 6. The inlet end of the open liquid guide frame 111 is located at the upper end of the second buffer plate 9. A rotating blade 113 is rotatably provided inside the open liquid guide frame 111. One end of the rotating blade 113 is fixedly connected to a connecting shaft 114. A liquid guide frame 111 is installed on one side. The device has a housing 115, one end of a connecting shaft 114 extends to the outside of the open frame 6 and is inserted into the housing 115. One end of the connecting shaft 114 is provided with a drive impeller 116. A water inlet 117 is opened on one side of the housing 115, and a water outlet 118 is opened at the bottom of the housing 115. The height of the water inlet 117 is higher than the height of the water outlet 118. The bottom end of the open liquid guide frame 111 is connected to a base frame 112. A filter frame 119 for filtering impurities is provided on the water inlet 117.

[0034] Working principle:

[0035] After the river water passes through the filter frame 119 to remove large debris, it enters the shell 115 through the inlet 117. The water in the shell 115 is discharged from the outlet 118. Since the inlet 117 is higher than the outlet 118, the water forms a directional flow under the natural settling of gravity, which drives the drive impeller 116 to rotate continuously. The drive impeller 116 drives the rotating blade 113 to rotate through the connecting shaft 114. When the rotating blade 113 rotates, a local low-pressure area is formed in the open liquid guide frame 111, thereby generating negative pressure. Negative pressure is generated at the inlet of the open liquid guide frame 111.

[0036] The negative pressure generated draws in the wastewater from the upper part of the perforated plate 10, allowing the wastewater in the lower part of the open frame 6 to pass through the perforated plate 10 and enter the upper part. This process removes and replaces the wastewater between the upper part of the perforated plate 10 and the planting pot 4, preventing localized stagnant water. At the same time, it releases fine particles from the upper part of the perforated plate 10 from the bottom of the open liquid guide frame 111, preventing debris from accumulating between the upper part of the perforated plate 10 and the planting pot 4, thus improving the wastewater treatment effect.

[0037] Example 3: When the negative pressure generated within the open liquid guide rack 111 is used to absorb wastewater between the upper end of the perforated plate 10 and the planting pot 4, if the suction is too weak, the wastewater replacement effect between the upper end of the perforated plate 10 and the planting pot 4 is poor; if the suction is too strong, it can easily damage the roots of aquatic plants. (Refer to...) Figure 6-7 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that it further includes a water flow impact transformation mechanism 12. The water flow impact transformation mechanism 12 includes an arc-shaped plate 121, which is fixedly connected to the open liquid guide frame 111. The arc-shaped plate 121 is located above the rotating blade 113. A first strip-shaped hole 122 is opened at the upper end of the arc-shaped plate 121. Guide plates 123 are fixedly connected to both sides of the first strip-shaped hole 122. One end of each guide plate 123 is fixedly connected to the inner wall of the open liquid guide frame 111. A partition 124 is installed on the inner wall of the open liquid guide frame 111. A narrow channel 125 is provided between the partition 124 and the open liquid guide frame 111. Several second connecting rods 126 are fixedly connected to the upper end of the perforated plate 10. The same third buffer plate 127 is fixedly connected to the upper end of the several second connecting rods 126. The third buffer plate 127 is located above the open liquid guide frame 111. Second strip holes 128 are opened on both sides of the upper end of the third buffer plate 127. Each second strip hole 128 is inclined towards the inner wall of the open frame 6.

[0038] Working principle:

[0039] After the arc plate 121, guide plate 123 and partition plate 124 are combined, the narrow channel 125 is connected to the first strip hole 122. When negative pressure is generated in the open liquid guide rack 111, the negative pressure is transmitted to the first strip hole 122 to form directional suction. When the suction flows through the narrow channel 125, the flow velocity increases and the pressure further decreases due to the narrowing of the flow cross section, which improves the extraction intensity of wastewater at the upper end of the perforated plate 10. It can more efficiently discharge the aging water and fine suspended particles accumulated above the perforated plate 10, improve the water quality renewal efficiency between the upper end of the perforated plate 10 and the planting pot 4, avoid local eutrophication caused by water stagnation, and improve the replacement effect of wastewater at the upper end of the perforated plate 10.

[0040] Furthermore, after the wastewater at the upper end of the perforated plate 10 is sucked out, it generates suction on the second strip hole 128. The second strip hole 128 absorbs the wastewater at the upper end of the third buffer plate 127. Since the second strip hole 128 is inclined towards the inner wall of the open frame 6, the resulting adsorption force acts on the edge area of ​​the inner wall of the open frame 6 and will not directly act on the bottom of the planting pot 4, so that the adsorption force on the bottom of the planting pot 4 is small. While ensuring the water replacement effect, it will not damage the roots of aquatic plants.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
