Description

Technical Field

[0001] The invention belongs to the technical field of ecological canals, and in particular relates to an ecologically restorable ecological canal. Background Art

[0002] The principle of ecological canal refers to improving the water quality and environment of the canal and improving the health of the ecosystem through a series of ecological measures. These measures include but are not limited to the establishment of wetlands, vegetation belts, sewage interception ditches, etc. These engineering measures can reduce the input of pollutants and improve the water purification capacity. At the same time, by adjusting the water flow rate and water level, the diversity and stability of the water ecosystem can be improved, and the self-repair and protection of the ecosystem can be promoted.

[0003] Filtration treatment is the most commonly used water restoration method in ecological canals, and is used to filter and remove large particles in the water flow. Traditional filtration in ecological canals is to fix the filter screen on the area where the water flows to filter the water flow. However, in actual use, this method requires regular maintenance and cleaning of the filter screen to avoid clogging of the filter screen due to long-term use, which greatly increases the workload of daily maintenance of ecological canals for staff.

[0004] For example, the Chinese invention patent CN115726323B proposes an ecological canal capable of ecological restoration, which can monitor the water flow inside the canal in real time through a water quality monitor. In cooperation with the first gate and the transfer canal, when the content of pollutants inside the water flow is large, it can be automatically transferred to the transfer canal, and combined with the filler layer inside the transfer canal to complete the water flow purification operation. That is, a filter is set at the water inlet and outlet of the transfer canal to filter the large particles of debris mixed in the water flow, but after long-term use, the large particles of debris will adhere to the filter and block the filter, which will seriously affect the actual flow of the water flow in this path, resulting in a significant reduction in the amount of water entering the transfer canal from the water inlet or a significant reduction in the amount of water flowing out of the transfer canal from the water outlet, thereby causing a significant reduction in the actual amount of water treated by the transfer canal. In more serious cases, the water flow cannot pass through the transfer canal, thereby causing the transfer canal to fail. Another example is the Chinese invention patent with publication number CN113800642B, which proposes an ecological interception ditch for farmland runoff pollution. The first filter screen and filter plate on the interception device can filter out pollutants in the ecological interception ditch. When the water in the ditch flows through the adsorption box, the substances in the adsorption box can greatly adsorb harmful substances such as nitrogen and phosphorus in the water, effectively reducing the nitrogen and phosphorus content in the water. The first filter screen also has the problem of being easily blocked after long-term use, which will affect the penetration of water flow, and in severe cases, will cause the repair performance of the device to fail. Summary of the invention

[0005] In view of the above-mentioned problems, the purpose of the present invention is to provide an ecological water channel that can be ecologically restored, which can clean the filter and effectively avoid the problem of filter clogging after long-term use.

The cleaning teeth are used to clean the blockages in the filter holes of the filter screen. The cleaning teeth can be inserted into the filter holes of the filter screen and mesh with the filter holes for transmission. The sliding of the filter screen is used to drive the roller body to rotate in the positive direction along the axis.

[0010] A driving assembly is arranged in the water diversion channel and is used to convert the energy generated by the water flow in the water diversion channel into mechanical energy. The driving assembly has an output end, which is connected to the traction assembly and is used to provide power to the traction assembly.

[0011] The energy storage elastic member is connected to the roller body. The rotation of the roller body drives the energy storage elastic member to deform and store energy. The energy storage elastic member is used to drive the roller body to rotate in the opposite direction along the axis.

[0013] A runner is rotatably arranged in the water diversion channel via a rotating shaft;

[0014] The speed regulating gear box comprises an input shaft and an output shaft. The input shaft is connected to the rotating shaft and rotates coaxially with the rotating shaft, and the output shaft is connected to the traction component and is used to provide power to the traction component.

[0015] Furthermore, the runner is arranged in the upper half of the height direction of the water diversion channel;

[0016] During dry spells, the water level in the diversion channel is below the rotor;

[0017] During the flood season, the water level in the water diversion channel rises but does not cover the impeller, and the water flow in the water diversion channel drives the impeller to rotate.

[0023] Furthermore, a slide groove is arranged at the bottom of the water diversion channel, and the installation frame is slidably arranged in the slide groove.

[0024] Furthermore, the traction assembly includes:

The traction assembly drives the sliding frame group to slide on the water diversion channel. The roller body rotates along the axis in the positive direction as the filter screen slides. Then the cleaning teeth clean the blockages in the filter holes of the filter screen and drive the energy storage elastic member to deform and store energy. When the driving assembly does not provide power to the traction assembly, the energy storage elastic member is used to drive the roller body to rotate in the opposite direction along the axis.

[0034] The present invention utilizes a driving component to convert the energy generated by the water flow into mechanical energy and transmits it to the traction component through the output end, further traction the filter to move, causing the roller to rotate along the axis in the positive direction as the filter slides, so that the cleaning teeth can clean the blockages in the filter holes of the filter. In addition, the filter also acts as a transmission member to transmit the sliding displacement to the energy storage elastic member through the rotation of the roller, causing the energy storage elastic member to deform and store energy.

[0045] It should be noted that the circuit connections involved in the present invention all adopt conventional circuit connection methods and do not involve any innovation.

[0046] Example 1

[0047] like Figure 1 , Figure 2 The ecologically restorable ecological canal shown has a water diversion canal 1, a sliding frame assembly 2, a traction assembly 3, a roller body 4, a driving assembly 5 and an energy storage elastic member 6.

[0048] The sliding frame assembly 2 is slidably arranged on the water diversion channel 1, and a filter screen 20 is arranged on the sliding frame assembly 2, and the filter screen 20 is used to filter the water in the water diversion channel 1. The traction component 3 has a traction end, which is connected to the sliding frame assembly 2 and is used to drive the sliding frame assembly 2 to slide on the water diversion channel 1. The sliding direction of the sliding frame assembly 2 intersects with the water flow direction in the water diversion channel 1, and the filter screen 20 slides with the sliding frame assembly 2.

[0049] like Figure 4As shown, the roller body 4 is rotatably arranged at any position tangent to the sliding path of the filter screen 20. A plurality of cleaning tooth groups 40 are evenly arranged on the roller body 4 along the circumference of the axis. Each cleaning tooth group 40 includes a plurality of cleaning teeth 400 from top to bottom. The cleaning teeth 400 are used to clean the blockages in the filter holes of the filter screen 20. The cleaning teeth 400 can be inserted into the filter holes of the filter screen 20 and mesh with the filter holes for transmission. The sliding of the filter screen 20 is used to drive the roller body 4 to rotate in the positive direction along the axis. The driving assembly 5 is arranged in the water diversion channel 1, and is used to convert the energy generated by the water flow in the water diversion channel 1 into mechanical energy. It has an output end, which is connected to the traction assembly 3 and is used to provide power to the traction assembly. The energy storage elastic member 6 is connected to the roller body 4. The rotation of the roller body 4 drives the energy storage elastic member 6 to deform and store energy. The energy storage elastic member 6 is used to drive the roller body 4 to rotate in the opposite direction along the axis. It should be noted that: as Figure 4 As shown, the energy storage elastic member 6 of this embodiment adopts a clockwork energy storage member, the inner end of which is fixed on the roller body 4, and the outer end is fixed on the shell, and the shell is arranged on the water diversion channel 1.

[0050] It should be noted that the sliding frame assembly 2 is arranged in the water diversion channel 1, and its total length is greater than the width of the water diversion channel 1, and the ratio of the effective length of the filter 20 to the water flow width of the water diversion channel 1 is 2:1. The effective length of the filter 20 is the length of the filter 20 projected on a plane perpendicular to the water flow direction. In addition, in actual assembly, the structure of the water diversion channel 1 needs to be adaptively adjusted according to the actual use of the water diversion channel 1, such as Figure 1 As shown, the water diversion channel 1 of this embodiment includes a main channel body and a placement channel for placing the sliding frame assembly 2 and the filter screen 20. The placement channel and the main channel body form a cross-shaped structure, and a seal is provided at the intersection of the main channel body and the placement channel, and the seal is closely attached to the filter screen 20. Figure 1 As shown, the roller body 4 is arranged at the initial position of the sliding frame assembly 2 .

[0051] Preferably, Figure 1 As shown, the driving assembly 5 includes a rotating wheel 51 and a speed regulating gear box 52 .

[0052] The rotating wheel 51 is arranged in the water diversion channel 1 through the rotating shaft. The speed regulating gear box 52 has an input shaft and an output shaft, the input shaft is connected to the rotating shaft and rotates coaxially, and the output shaft is connected to the traction assembly 3 and is used to provide power to the traction assembly. Among them, the speed regulating gear box 52 of this embodiment adopts a commercially available gear reduction box.

[0053] Preferably, the impeller 51 is disposed in the upper half of the water diversion channel 1 in the height direction.

[0054] During the dry season, the water level of the water diversion channel 1 is below the runner 51. During the flood season, the water level of the water diversion channel 1 rises and does not exceed the runner 51, and the water flow in the water diversion channel 1 drives the runner 51 to rotate.

[0055] Since the water level of the ecological canal is not fixed, the water level in the canal changes over time, which is mainly affected by factors such as climate change, human activities, and the allocation and management of water resources. Therefore, the water level of the water diversion channel 1 will drop during the drought period, and the water level of the water diversion channel 1 will rise during the flood season. Based on this, the runner 51 in the water diversion channel 1 of the ecological canal is selectively adjusted to meet the actual application in different regions. It should be noted that: Under normal circumstances, it is necessary to ensure that the filter 20 is in a fixed state, and then the filtering process can be effectively carried out, that is, it is necessary to ensure that the traction component 3 has no traction on the sliding frame group 2, so the drive component 5 in this state does not need to do work. The filter 20 is cleaned only after it has been used for a period of time. Therefore, this process can be a fixed cycle or a non-fixed cycle. In this embodiment, the actual position of the runner 51 is adjusted based on the natural law of the rising water level in the flood season. During the flood season, the water level can rise to cover the runner 51, which in turn causes the water flow to drive the runner 51 to rotate, thereby ensuring that the traction assembly 3 pulls the sliding frame group 2 to slide. At this time, the cleaning teeth 400 clean the blockages in the filter holes of the filter screen 20. The energy storage elastic member 6 is deformed and stored through the rotation of the roller body 4. After the flood season, the water level drops again. At this time, the energy storage elastic member 6 drives the roller body 4 to rotate in the opposite direction along the axis, and causes the sliding frame group 2 to slide in the opposite direction to achieve reset.

[0056] Preferably, the sliding direction of the sliding frame assembly 2 is perpendicular to the water flow direction in the water diversion channel 1. The sliding direction of the sliding frame assembly 2 maximizes the actual contact area between the corresponding roller body 4 and the filter screen 20 after sliding, and maximizes the actual cutting area of ​​the water flow by the filter screen 20, thereby enabling the filter screen 20 to filter the water in the water diversion channel 1 more effectively and to clean the filter screen 20 to the greatest extent.

[0057] Preferably, Figure 3 As shown, the sliding frame assembly 2 includes a mounting frame 21 , an edge strip 22 and a water retaining member 23 .

[0058] The mounting frame 21 is a rectangular frame structure, which is slidably arranged in the water diversion channel 1. The filter screen 20 is arranged on the mounting frame 21. There are two edge strips 22, which are respectively located at the two ends of the mounting frame 21 and are arranged on the water diversion channel 1. The two edge strips 22 respectively form two mounting intervals with the side of the mounting frame 21. There are two water retaining members 23, which are telescopic structures. The two water retaining members 23 are arranged in two mounting intervals in a one-to-one correspondence. The water retaining member 23 is used to perform water retaining treatment on the empty space formed by the mounting frame 21 and the water diversion channel 1 after sliding. The water retaining member 23 of this embodiment adopts a water retaining plate composed of a plurality of soft silicone water retaining strips connected in sequence.

[0059] Preferably, a slide groove 10 is provided at the bottom of the water diversion channel 1 , and the installation frame 21 is slidably disposed in the slide groove 10 .

[0060] Preferably, Figure 1 As shown, the traction assembly 3 includes a wire drum 31 and a traction wire 32 .

[0061] The wire drum 31 is rotatably mounted on the water diversion channel 1 via a mounting shaft, and the mounting shaft is connected to the output end and rotates coaxially. One end of the traction wire 32 is mounted on the wire drum 31 , and the other end is connected to the sliding frame assembly 2 .

[0062] Preferably, the traction assembly 3 further includes a guide roller 33 , which is rotatably disposed in the water diversion channel 1 to guide the traction line 32 .

[0063] The working principle of the above embodiment is:

[0064] The water level in the water diversion channel 1 is below the rotating wheel 51, the driving assembly 5 does not operate and cannot drive the traction assembly 3, the sliding frame assembly 2 is not subjected to force and remains fixed, and the filter screen 20 is in a fixed state for filtering.

[0065] When the water level in the water diversion channel 1 rises and is above the impeller 51, the water flow drives the impeller 51 to rotate, and the speed regulating gear box 52 drives the wire drum 31 to rotate. The wire drum 31 tightens the traction wire 32, and then pulls the sliding frame group 2 to slide in the direction of tightening the traction wire 32. Among them, the sliding frame group 2 slides along the slide groove 10. Since the roller body 4 is rotatably set at a position tangent to the sliding path of the filter screen 20, the filter holes of the filter screen 20 are meshed with the cleaning teeth 400, and the roller body 4 rotates to clean the filter holes of the filter screen 20. The cleaning teeth 400 are used to clean the filter holes of the filter screen 20. The roller body 4 rotates and drives the energy storage elastic member 6 to deform and store energy. When the water level drops below the impeller 51, the energy storage elastic member 6 drives the roller body 4 to rotate in the opposite direction along the axis, and prompts the sliding frame group 2 to slide in the opposite direction to achieve reset.

[0066] Example 2

[0067] The difference from Example 1 is that: preferably, Figure 5 , Figure 6 As shown, a resistance component 7 is also included. The resistance component 7 is arranged on the water diversion channel 1 and connected to the sliding frame group 2, and is used to reversely pull the sliding frame group 2 to provide initial resistance.

[0068] Preferably, the resistance assembly 7 includes an adjustment slot 71 , an elastic member 72 and a displacement adjustment member 73 .

[0069] The adjustment groove 71 spans the water diversion channel 1 and is parallel to the sliding direction of the sliding frame assembly 2. The elastic member 72 is placed in the adjustment groove 71, and one end of the elastic member 72 away from the sliding direction of the sliding frame assembly 2 is connected to the sliding frame assembly 2 through a connecting rod, and the other end is connected to the end of the adjustment groove 71 through a displacement adjustment member 73. In this embodiment, the displacement adjustment member 73 is a long screw, and the compression state of the elastic member 72 in the initial state is determined by fixing the long screw at different positions on the adjustment groove 71.

[0070] In actual use, the resistance component 7 can be used to increase the initial resistance of the sliding frame group 2. When the water level is above the rotating wheel 51, the water flow drives the rotating wheel 51 to rotate, and the speed regulating gear box 52 drives the wire drum 31 to rotate. The traction force generated by the traction wire 32 on the sliding frame group 2 is:

[0071] When the flow rate of the water flow is low, and the traction force generated by the traction line 32 on the sliding frame assembly 2 is smaller than the initial resistance generated by the resistance assembly 7 , the traction line 32 cannot pull the sliding frame assembly 2 .

[0072] When the flow rate of the water flow is high, and the traction force generated by the traction line 32 on the sliding frame assembly 2 is greater than the initial resistance generated by the resistance assembly 7, the traction line 32 pulls the sliding frame assembly 2 to slide.

[0073] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
