Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment devices, and particularly relates to a river ecological restoration device and restoration method. Background Technology

[0002] In recent years, with the rapid development of urban construction, a large amount of domestic and industrial wastewater has flowed into rivers, leading to increasingly serious river pollution. Currently, in addition to cutting off the source of sewage discharge and treating sewage to meet standards before discharge, various biological agents are regularly added to rivers to utilize the metabolic functions of these microorganisms to decompose and transform pollutants in the water, thereby achieving the goal of ecological restoration of the river.

[0003] Traditional methods of applying biological agents involve manual spraying or using spraying equipment mounted on boats. These methods are typically time-sensitive and cannot provide continuous application over a period of time. Furthermore, the agents applied using these methods mostly remain suspended on the shallow surface of the water, which is insufficient for treating pollutants at the bottom of rivers. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a river ecological restoration device and method that can continuously and automatically deliver biological agents to the bottom of the river over a period of time, thereby improving the treatment effect on pollutants at the bottom of the river.

[0005] In order to achieve the objective of this invention, the following solution is proposed:

[0006] A river ecological restoration device includes: a feed pipe, an impeller, a piston, and a weight.

[0007] The top of the material tube is sealed, and the bottom is open. The upper section of the side wall has a discharge hole. The bottom of the material tube has a connecting rod, and the bottom of the connecting rod has a weight. The inside of the material tube has a piston that slides along the axis of the material tube.

[0008] The impeller includes two coaxially arranged ring-shaped frames with multiple blades arranged in a circumferential array between the frames. The frames are coaxially fitted onto the outside of the material tube. A through hole is opened on the side wall of the upper frame. The through hole and the discharge hole are located at the same height as the material tube, and the discharge hole is located within the width range of the frame.

[0009] The air bladder is connected to the piston via a rope that passes through the top of the feed tube. When the bacterial agent is released, the air bladder is below the water surface.

[0010] The beneficial effects of this invention are as follows: it can achieve the purpose of direct, automatic and continuous delivery of bacterial agents to the bottom of the river, which can effectively improve the effect of bacterial agents on the treatment of pollutants on the river bottom, and has a prompt function after the bacterial agent delivery is completed, which is convenient for management; and it has a marking and positioning function, which is convenient for the device to be retrieved and is conducive to the reuse of the device.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1, as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a river ecological restoration device includes: a material pipe 1, a connecting rod 2, a weight 3, a piston 4, and an impeller 5.

[0021] The top of the material pipe 1 is a sealed structure, and the bottom is an open structure. The upper section of the side wall is provided with a discharge hole 11. The bottom of the material pipe 1 is provided with a connecting rod 2, and the bottom of the connecting rod 2 is provided with a weight 3. The weight 3 is a cement block or an iron block, which is used to fix the device to the bottom of the river. The material pipe 1 is provided with a piston 4, which is slidably arranged along the axis of the material pipe 1.

[0022] The impeller 5 includes two coaxially arranged ring-shaped skeletons 51, with multiple blades 52 arranged in a circumferential array between the skeletons 51. The skeletons 51 are coaxially sleeved on the outside of the material tube 1. A through hole 511 is opened on the side wall of the upper skeleton 51. The through hole 511 and the discharge hole 11 are located at the same height as the material tube 1, and the discharge hole 11 is located within the width range of the skeleton 51.

[0023] The airbag 6 is connected to the piston 4 by a pull rope 61 that passes through the top of the feed tube 1. The hole at the top of the feed tube 1 for the pull rope 61 is equipped with a rubber ring to achieve a sealing effect. When the bacterial agent is released, the airbag 6 is below the water surface.

[0024] Preferably, a protective net is laid on the outside of the airbag 6 to protect the airbag 6 from being torn by objects flowing in the water.

[0025] Preferably, the connection between the connecting rod 2 and the weight 3 is a ball joint structure. When the weight 3 falls on the uneven riverbed, the material pipe 1 can remain vertical under the buoyancy of the air bag 6, preventing the material pipe 1 from tipping over or even lying flat on the riverbed, thus affecting the rotation of the impeller 5. At this time, the axes of the connecting rod 2 and the weight 3 are in an inclined state.

[0026] Further preferred, such as Figure 2 As shown, the lower end side wall of the connecting rod 2 is provided with a stop block 21. There is a gap between the stop block 21 and the top surface of the weight block 3 to avoid affecting the swing of the connecting rod 2 around the ball joint point. The top surface of the weight block 3 is provided with a stop pin 31 to abut against the stop block 21 to prevent the connecting rod 2 from rotating around the ball joint point, so that the material tube 1 remains relatively fixed along the circumference.

[0027] Preferred, such as Figure 4 As shown, when the piston 4 is at the bottom of the feed tube 1, the airbag 6 contacts the top surface of the feed tube 1 to shorten the overall length of the device, thus facilitating transportation; when the device is deployed, it can avoid excessive horizontal positional difference between the airbag 6 and the weight 3, which would cause the landing point of the weight 3 to deviate too much from the expected position; and by bringing the airbag 6 closer to the feed tube 1, the length of the pull rope 61 extending from the top of the feed tube 1 can be shortened, allowing the airbag 6 to better straighten the feed tube 1, making the feed tube 1 more vertical, thereby ensuring the impact effect of the water flow on the blade 52.

[0028] Preferred, such as Figure 3As shown, the projection of the blade 52 on the radial side of the feed pipe 1 is inclined relative to the axis of the feed pipe 1, thereby ensuring that even when the feed pipe 1 is in a horizontal state, the water flow enters from the end of the impeller 5, and the blade 52 can drive the impeller 5 to rotate with the help of the water flow, so as to always maintain the feeding state.

[0029] Preferred, such as Figure 6 As shown, the piston 4 has a winding reel 7 inside for winding the pull rope 61. The outer side of one end of the winding reel 7's shaft has a toothed structure. A push rod 8 is vertically inserted through the piston 4. The upper end of the push rod 8 protrudes from the top surface of the piston 4, and a spring 81 is provided between the top of the push rod 8 and the top surface of the piston 4. The lower section of the push rod 8 has a locking tooth 821. When the spring 81 is in its natural state, the locking tooth 821 is connected to the tooth of the winding reel 7 to lock the winding reel 7 and prevent it from rotating. More specifically, the lower section of the push rod 8 has a rectangular frame 82. The rectangular frame 82 is fitted onto the outside of the toothed end of the winding reel 7 to prevent the push rod 8 from rotating. The bottom surface inside the rectangular frame 82 has a locking tooth 821. When the spring 81 is in its natural state, the locking tooth 821 is engaged with the tooth of the winding reel 7 to achieve the connection between the locking tooth 821 and the tooth. When the push rod 8 moves downward relative to the piston 4, the locking tooth 821 separates from the tooth of the reel 7, and the pull rope 61 wound on the reel 7 is released. The length of the pull rope 61 wound on the reel 7 is greater than the depth of the river, so that the airbag 6 can float on the water surface, making it easier to be found and thus easier to determine the location of the device, so as to retrieve the device and thus realize the reuse of the device.

[0030] Preferably, the bottom of the piston 4 is provided with a sealing plate to prevent debris from entering the piston 4 and affecting the rotation of the winding wheel 7, and the sealing plate can be removed to facilitate the operation of the winding wheel 7 to wind the rope 61.

[0031] The principle of bacterial agent dispensing is as follows: After the device enters the water, under the impact of the water flow, the blades 52 will drive the impeller 5 to rotate. When the impeller 5 rotates to a predetermined angle, as... Figure 5 As shown, the through hole 511 will coincide with the discharge hole 11. Since the airbag 6 always has an upward buoyancy, it also always exerts an upward pulling force on the piston 4, causing the piston 4 to press against the top of the feed tube 1. When the through hole 511 coincides with the discharge hole 11, under the pressure of the piston 4, the bacterial agent in the feed tube 1 will be discharged outward through the discharge hole 11 and the through hole 511, thereby achieving the purpose of adding bacterial agent. The discharged bacterial agent will quickly spread to the surrounding area under the stirring action of the blade 52, so that the bacterial agent can fully contact the water, thereby better exerting the effect of the bacterial agent. When the through hole 511 and the discharge hole 11 are misaligned, the discharge hole 11 will be covered by the skeleton 51, thereby sealing the discharge hole 11. The purpose is to achieve intermittent discharge to extend the feeding time.

[0032] After the bacterial agent inside the feed pipe 1 has been discharged, the piston 4 will move to the upper end of the feed pipe 1 and make the push rod 8 contact the top of the feed pipe 1. At this time, the air bag 6 will still exert an upward pulling force on the piston 4. This pulling force will cause the piston 4 to move upward relative to the push rod 8, thereby separating the locking tooth 821 from the tooth of the winding reel 7, thus releasing the pull rope 61 wound on the winding reel 7, and causing the air bag 6 to float to the water surface as a signal that the bacterial agent has been discharged. At the same time, it is convenient for workers to locate and retrieve the device.

[0033] Example 2, a method for river ecological restoration, implemented using the river ecological restoration device described in Example 1, includes the following steps:

[0034] S1: Filler, invert the feed pipe 1, load the biological agent powder or mixed liquid into the feed pipe 1, load the piston 4 from the bottom of the feed pipe 1, and use the pull rope 61 to pull the piston 4 to the top of the feed pipe 1. At this time, to prevent the piston 4 from falling off, the pull rope 61 can be knotted at the top surface of the feed pipe 1 to fix the pull rope 61 and thus prevent the piston from falling off; rotate the impeller 5 to offset the through hole 511 from the discharge hole 11 to prevent the agent from leaking.

[0035] S2: Deployment. The river ecological restoration device containing the bacterial agent is deployed to the predetermined location in the river by boat. Under the action of the weight 3, the device will be fixed at a predetermined height above the riverbed. The device will automatically release the bacterial agent under the impact of the flowing water. The height of the device above the riverbed can be controlled by setting connecting rods 2 of different lengths.
