Description

Technical Field

[0001] The present invention relates to the technical field of urban wetland protection, and in particular to an urban wetland management and protection device and method. Background Art

[0002] Urban wetland management and protection contribute to the sustainable development of the urban economy and maintain the ecological balance of the entire city. Take the Yellow River Delta wetlands as an example. The Yellow River Delta is a typical representative of wetlands, with rich ecosystem restoration, high productivity and economic potential. However, with the reclamation and development projects such as agriculture, marine aquaculture, oil extraction and salt industry, large-scale loss of coastal wetlands, decline in biodiversity and increased water pollution load have occurred. Therefore, wetland management and protection are needed.

[0003] At present, in the process of managing and protecting the Yellow River Delta wetland, water purification is a crucial link. In this link, wetland plants are usually planted in the canal that introduces water flow into the Yellow River Delta wetland to reduce the water nutrients in the water flow. At the same time, filter net structures are set to intercept suspended matter, particulate matter and other debris in the water flow to reduce the pollutant load entering the wetland. Although the above water quality treatment can effectively improve the ecological environment of the Yellow River Delta wetland, it still has the following defects: after long-term use, the debris intercepted by the filter net structure will gradually accumulate. If it is not cleaned in time, it will cause clogging of the filter net and affect its normal interception function. Once the filter net is clogged, it will cause poor water flow, affect the normal operation of the wetland ecosystem, and be detrimental to the management and protection of the wetland. At present, it is usually manually cleaned and maintained regularly by humans, which is troublesome to use, increases the labor intensity, and has certain dangers. To this end, we propose an urban wetland management and protection device and method. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Please refer to the attached Figure 1 -Attached Figure 2

[0042] An urban wetland management and protection device is used to purify water entering the urban wetland through a canal in the urban wetland. The device includes wetland plants planted inside and on the top of the canal. The wetland plants, such as reeds, Suaeda salsa and Tamarix chinensis, are used to purify the flowing water and absorb nutrients such as nitrogen and phosphorus in the water, as well as harmful substances such as heavy metals. The device also includes:

[0043] The mounting seat 1 is arranged in the canal, and can be arranged on one side of the wetland plants in the canal, so that the flowing water passes through the mounting seat 1 and then passes through the wetland plants; a filter 2 is arranged in the mounting seat 1, and the mounting seat 1 is in a circular shape, and has a through opening at one end of the top, and the filter 2 is, for example, a filter net;

[0044] The collecting mechanism 5 is provided on one side of the filter element 2 and is used to clean the filter element 2 and collect the debris intercepted by the filter element 2, and specifically corresponds to the opening position of the mounting seat 1;

[0045] A driving mechanism, disposed in the mounting seat 1, for driving the collecting mechanism 5 to move up and down;

[0046] The recovery shell 8 is detachably mounted on the top of the mounting seat 1, and the top of the recovery shell 8 is hollow; and

[0047] The material-moving mechanism is disposed above the recovery shell 8 and is used to move the debris on the collection mechanism 5 into the recovery shell 8 when the collection mechanism 5 moves upward to a preset position.

[0048] Please refer to the attached Figure 3 -Attached Figure 5

[0049] Preferably, the collecting mechanism 5 of this embodiment includes:

[0050] The perforated collecting plate 51 is arranged on one side of the filter element 2, specifically on the side where the water flow impacts the filter element 2. The debris intercepted by the filter element 2 will remain at the top position of the perforated collecting plate 51. The bottom of the perforated collecting plate 51 is slidably provided with a scraper 52 for contacting the bottom inner wall of the mounting seat 1. The perforated collecting plate 51 can be slidably connected with the slider on the scraper 52 through the sliding groove provided at the bottom. The scraper 52 is located at the end of the bottom of the perforated collecting plate 51 away from the filter element 2 when the perforated collecting plate 51 is at the lowermost end of the filter element 2. In this case, the scraper 52 can prevent the debris from entering the position between the scraper 52 and the bottom inner wall of the mounting seat 1; and,

[0051] The housing 54 is embedded on the perforated collecting plate 51. A movable block 57 is movably provided in the inner cavity of the housing 54. The side of the movable block 57 away from the filter element 2 is connected to the output end of a telescopic device 59 provided in the housing 54. The telescopic device 59 is, for example, an electric telescopic rod. The movable block 57 can be driven to move by the telescopic device 59. The movable block 57 is connected to one end of a pull rope 56. The other end of the pull rope 56 movably passes through the housing 54 toward the side of the filter element 2 and is connected to the scraper 52.

[0052] When the movable block 57 moves in a direction away from the filter element 2, the scraper 52 is pulled toward the filter element 2 through the pull rope 56. An elastic member for driving the scraper 52 to return to its original position is provided at the bottom of the perforated collecting plate 51.

[0053] When the perforated collecting plate 51 is upward, the movable block 57 can be driven by the telescopic device 59 to move to the side away from the filter element 2, and then the movable block 57 pulls the scraper 52 to move toward the filter element 2 through the pull rope 56. When the perforated collecting plate 51 is downward to a preset position, the bottom of the scraper 52 contacts the bottom inner wall of the mounting seat 1, and then the telescopic device 59 drives the movable block 57 to move to the side close to the filter element 2. At this time, the scraper 52 is reset under the action of the elastic member to push the debris remaining on the bottom inner wall of the mounting seat 1 away from the bottom inner wall of the mounting seat 1. This method can prevent some debris from being intercepted by the water flowing through the filter element 2 and being on the bottom inner wall of the mounting seat 1 during the upward movement of the perforated collecting plate 51, thereby preventing it from being compacted on the bottom inner wall of the mounting seat 1 by the downward perforated collecting plate 51, thereby affecting the use of the filter element 2.

[0054] Preferably, the collecting mechanism 5 of this embodiment further includes:

[0055] A cleaning plate 53 is used to fit with the filter element 2. The cleaning plate 53 is, for example, a brush plate. When the cleaning plate 53 moves upward with the perforated collecting plate 51, the filter element 2 can be cleaned to prevent the filter element 2 from being blocked. One end of the cleaning plate 53 is inserted into a movable opening opened in the outer wall of the perforated collecting plate 51 facing the filter element 2, so that the cleaning plate 53 can move horizontally relative to the filter element 2. A connecting rod 55 is provided at the bottom of the cleaning plate 53. One end of the connecting rod 55 away from the cleaning plate 53 movably penetrates the perforated collecting plate 51 and the outer shell 54 and is connected to a connecting block 510. The connecting block 510 is movably arranged in the outer shell 54 and is spaced apart on the side of the movable block 57 facing the filter element 2. A protrusion is integrated with the outer shell 54 at a position between the connecting block 510 and the movable block 57; and,

[0056] The buckle structure 58 is used to connect the movable block 57 and the connecting block 510. The buckle structure 58 is, for example, an arc-shaped elastic clamp provided on the connecting block 510 and a clamping ball provided on the movable block for clamping into the arc-shaped elastic clamp. When the connecting block 510 contacts the protrusion, the cleaning plate 53 is separated from the filter element 2. When the buckle structure 58 continues to move after the movable block 57 contacts the protrusion, the movable block 57 and the connecting block 510 are separated.

[0057] Please refer to the attached Figure 5 As shown, when the movable block 57 moves to the side away from the filter element 2, the movable block 57 drives the connecting block 510 to move through the snap structure 58, and then the connecting block 510 drives the cleaning plate 53 to separate from the filter element 2 through the connecting rod 55. When the connecting block 510 contacts the protrusion, the movable block 57 continues to move, which will cause the movable block 57 and the connecting block 510 to separate, so that the movable block 57 continues to move. In this way, the cleaning plate 53 can be separated from the filter element 2 when the perforated collecting plate 51 moves downward, so as to avoid the cleaning plate 53 pushing the particles filtered by the filter element 2 downward in the process of the perforated collecting plate 51 moving downward, resulting in the filtered particles being compacted and remaining between the bottom inner wall of the mounting seat 1 and the perforated collecting plate 51.

[0058] Preferably, the driving mechanism of this embodiment includes:

[0059] Two sets of guide rails 3 are respectively embedded in the inner walls of both sides of the mounting seat 1. The height of the guide rail 3 is greater than the height of the mounting seat 1. A lead screw 4 is rotatably arranged in the guide rail 3. A slider that can move in the guide rail 3 is threadedly sleeved on the outer wall of the lead screw 4. The slider is fixed to the side wall of the perforated collecting plate 51; and,

[0060] A fixed plate is fixed on the top of two sets of guide rails 3. A protective shell 7 is provided on the top of the fixed plate. A rotating device 6 is provided on the top of the protective shell 7. The output end of the rotating device 6 extends into the protective shell 7 and is connected to the lead screw 4. The rotating device 6 is a servo motor. The output end of the rotating device 6 and the lead screw 4 can be connected to each other through a sprocket transmission group (including a sprocket and a chain). By opening the rotating device 6, the lead screw 4 can be driven to rotate synchronously in the same direction, thereby moving the perforated collecting plate 51 upward or downward.

[0061] Preferably, the material-selecting mechanism of this embodiment includes:

[0062] A second guide rail 9 is provided at the bottom of the fixed plate, the second guide rail 9 is perpendicular to the fixed plate, a second scraper 10 is slidably provided in the second guide rail 9, and the second scraper 10 is used to contact the top of the collecting mechanism 5 when the collecting mechanism 5 moves upward to a preset position; and,

[0063] The second telescopic device is arranged at one end of the guide rail 9, and its output end is connected to the scraper 10 for driving the scraper 10 to move along the guide rail 9. The second telescopic device is, for example, an electric telescopic rod. When the collecting mechanism 5 moves upward to a preset position, its top contacts the bottom of the scraper 10. By driving the scraper 10 to move by the second telescopic device, the debris on the collecting mechanism 5 can be moved into the recovery shell 8.

[0064] Preferably, a detection sensor 13 is provided on the top of the inner wall of one of the guide rails 3 of the present embodiment. The detection sensor 13 is, for example, a pressure sensor, and its model is selected according to actual conditions, which will not be described in detail herein. The detection sensor 13 is electrically connected to the electrical mechanism 11, and the electrical mechanism 11 includes a wireless communicator and a controller for controlling the rotating device 6, the telescopic device 1 59 and the telescopic device 2. The wireless communicator is used for the device to remotely connect to an external management terminal, and the user can remotely control the operation of the electrical components in the device through the wireless communicator. The detection sensor 13 contacts the collecting mechanism 5 when the collecting mechanism 5 moves upward to a preset position, and then the detection sensor 13 sends a signal to the controller, so that the controller controls the rotating device 6, the telescopic device 1 59 and the telescopic device 2 to work, specifically controlling the telescopic device 1 59 to drive the movable block 57 to move to the side away from the filter element 2, the rotating device 6 to stop working, and the telescopic device 2 to drive the scraper 2 10 to move toward the recovery shell 8.

[0065] It should be noted that photovoltaic components (including photovoltaic panels and batteries, etc.) can also be installed in the device to power the electrical devices in the device, which will not be described in detail here.

[0066] Please refer to the attached Figure 6

[0067] As a preferred embodiment, a support frame 12 is provided at the top of the mounting base 1 and on both sides of the recovery shell 8. A toothless gear 14 is rotatably provided at the top of the support frame 12. A nozzle 15 is rotatably provided at the top of the support frame 12 and on one side of the toothless gear 14 through a rotating shaft and a torsion spring.

Specifically, the shaft of the toothless gear 14 and the lead screw 4 are transmission-connected by a sprocket transmission group. The nozzle 15 is connected to the output end of the pump body 16 through a pipeline. When the lead screw 4 rotates, the toothless gear 14 is driven to rotate at the same time. The toothless gear 14 intermittently drives the driven gear, so that the rotating shaft drives the nozzle 15 to reciprocate. The pump body 16 is arranged on the side wall of the protective shell 7, and one end of the impeller shaft of the pump body 16 extends into the protective shell 7 and rotates with the rotating The output end of the device 6 is transmission connected, and the impeller shaft of the pump body 16 and the output end of the rotating device 6 can be transmission connected by a bevel gear set (two sets of meshing bevel gears). The output end of the pump body 16 is connected to an inlet head 18 through an inlet pipe 17, and the inlet head 18 is in the canal; when the rotating device 6 is working, it also drives the impeller shaft of the pump body 16, thereby making the pump body work, and the pump body allows the liquid in the canal to enter the nozzle 15 through the inlet head 18 and the inlet pipe 17, and is sprayed from the nozzle 15 to irrigate the wetland plants on both sides of the canal.

[0069] A method for urban wetland management and protection, using the above-mentioned device, comprises the following steps:

[0070] S1: Plant wetland plants on the top and inside of the canals in urban wetlands to initially purify the water flowing in the canals so as to absorb nutrients such as nitrogen and phosphorus, as well as harmful substances such as heavy metals in the water;
