Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ecological restoration, and particularly relates to a city ecological restoration device and method. BACKGROUND

[0002] The city ecology is a complex system composed of water bodies, soil, atmosphere, plants and animals, among which the city water body is an indispensable part of the city blue-green ecological space, which not only provides a place for residents to relax and entertain, but also adjusts the city microclimate and maintains biodiversity. Artificial lakes are a common type of city blue space, which is of great significance to the health of the city ecological system.

[0003] Artificial lakes, also known as man-made lakes, are water bodies created by human engineering. They are distributed in the city and its surroundings. Artificial lakes have functions such as water resource storage and supply, flood control, water landscape shaping, and ecological conservation. Since they are enclosed water areas surrounded by dams, the water flow is small and the water exchange is limited. At the same time, artificial lakes are often close to human production and living areas and often face serious water surface pollution problems, which are not easily diluted or removed by nature. In addition, the leaves of trees around the artificial lake fall on the water surface, which will affect the water ecological system and the beauty of the artificial lake, so effective technical means or devices are needed to clean up in time.

DETAILED DESCRIPTION

[0031] In order for those skilled in the art to better understand the present application, the technical solutions of the present application are further described below in combination with the drawings and examples.

[0032] Example 1: as Figures 1-8The utility model discloses a kind of urban ecological restoration devices, including buoyancy tank 1 and floating mechanism 11, landscape water spraying device 10 is installed on the upper end of buoyancy tank 1, it is characterized by: buoyancy tank 1 is opened with several openings matched with floating mechanism 11, collection groove 12 is installed in buoyancy tank 1 with several openings matched, water pipe 13 is penetrated in the middle of buoyancy tank 1 and is communicated with landscape water spraying device 10, upper and lower movement mechanism is installed in buoyancy tank 1, and upper and lower movement mechanism is connected with several baffle plates 14 with the sliding connection of buoyancy tank 1, several baffle plates 14 are matched with opening, storage groove 15 is opened in collection groove 12 with the communication of opening, trapezoidal plate 16 is fixedly installed with the sealed connection of storage groove 15 in baffle plate 14, lower one-way communication groove 17 and upper one-way communication groove 18 are opened in collection groove 12 with several openings are communicated, two-way pump 19 is installed in buoyancy tank 1 with water pipe 13 is communicated, several upper one-way communication grooves 18 and lower one-way communication grooves 17 are communicated with water pipe 13, and several upper one-way communication grooves 18 and lower one-way communication grooves 17 are installed with filter screen 20;

[0033] Connection groove 18 and lower one-way communication groove 17 are opened in the side surface of collection groove 12 with slope 21, and scraper strip 22 is slidably connected with lower one-way communication groove 17 in collection groove 12, scraper strip 22 is fixedly connected with push rod 23 that extends into the inside of collection groove 12, and push rod 23 is installed with reciprocating mechanism.

[0034] Buoyancy tank 1 is placed in water surface, in turn under the buoyancy effect of floating mechanism 11, water surface is located in the lower side of opening, or also can be installed support rod with buoyancy tank 1 in the bottom of closed water area, which can save the installation of floating mechanism 11 while ensuring that water surface is located in the lower side of opening;Upper one-way communication groove 18 and lower one-way communication groove 17 are provided with one-way valve inside, and the communication groove can only flow into water pipe 13 in one-way valve by one-way valve;Normal state can be pumped by the output end of two-way pump 19 extending into water to transport water below water surface upwards, in turn, from landscape water spraying device 10, play beautiful and oxygenation effect;

[0035] When the water surface is needed to be cleaned, the baffle 14 is driven to move downward by the up-down movement mechanism, so that the baffle 14 leaks out of the opening and is lower than the water surface, at this time, water will enter the inside of the collecting groove 12 under the action of gravity, at this time, the water between the collecting groove 12 and the buoyancy tank 1 is pumped by the bidirectional pump 19, and then the water enters the inside of the lower one-way communication groove 17 through the filter screen and is finally discharged into the water area from the lower side output end of the bidirectional pump 19, the water surface is driven to move close to the buoyancy tank 1 by the cooperation of the bidirectional pump 19 and the baffle 14 being lower than the water surface, and then the water surface garbage moves to the collecting groove 12, the garbage is located in the inside of the collecting groove 12 under the action of the water pumping of the lower one-way communication groove 18, until the baffle 14 and the trapezoidal plate 16 are driven to move upward by the up-down movement mechanism to seal the opening, at this time, since the slope of the trapezoidal plate 16 is inclined to the center of the baffle 14, the water flow will be pushed into the collecting groove 12 on the slope of the trapezoidal plate 16 in the process of the movement of the trapezoidal plate 16, so that the upward movement of the trapezoidal plate 16 will leak out of the storage groove 15, facilitating the downward movement of the garbage inside to the inside of the storage groove 15, and the slope 21 of the collecting groove 12 can also make the garbage inside move downward to avoid residue, and the filter screen 20 is scraped by the reciprocating mechanism to reciprocate the scraping strip 22 to avoid being blocked and unable to generate suction.

[0036] At the same time, since the opening part is located on the upper side of the water surface, the upper one-way communication groove 18 pumps air under the action of the bidirectional pump 19, and then the air enters the water pipe 13 and mixes with the water solution pumped by the lower one-way communication groove 17, so as to improve the oxygen content of the water body.

[0037] The present application can repair the water ecological environment of the closed water area, collect the garbage on the surface of the closed water area, mix the air pumped with the water solution at the same time of collecting the garbage, finally flow into the closed water area to improve the oxygen content of the water body and the water quality, and also can supplement oxygen to the closed water area through the landscape water spraying device 10 under normal conditions.

[0038] In the embodiment 1, the storage groove 15 is provided with a rectangular groove 30 at the lower side, a lower plate 31 is sealingly and rotatably connected in the rectangular groove 30, a limiting frame 32 matched with the up-down movement mechanism is fixedly installed in the buoyancy tank 1, an inclined plate 33 is fixedly installed in the limiting frame 32, a locking assembly is transmissionally connected with one of the rotating shafts of the lower plate 31, a collecting tank 34 matched with the bidirectional pump 19 is detachably installed at the lower end of the buoyancy tank 1, and a one-way hole is arranged between the storage groove 15 and the lower one-way communication groove 17.

[0039] The one-way through hole is internally provided with a filtering assembly and also provided with a one-way valve to avoid garbage entering the one-way through hole. When the baffle 14 is opened, the trapezoidal plate 16 seals the upper end of the storage tank 15 to avoid the garbage accumulated in the storage tank 15 from being dispersed. Until the baffle 14 moves upward to close the opening, the trapezoidal plate 16 leaks out of the storage tank 15, and the garbage in the storage tank 15 is flowed into the storage tank 15 by the action of the slope of the trapezoidal plate 16 and the water flow. At this time, the bidirectional pump 19 can suck the residual water in the storage tank 15 through the lower one-way communication groove 17 and the one-way through hole. When the bidirectional pump 19 delivers water to the landscape water spraying device 10, the upper one-way communication groove 18, the lower one-way communication groove 17 and the one-way through hole cannot flow, and thus the water solution cannot enter the inner wall of the storage tank 15.

[0040] When garbage needs to be collected, the discharge plate 31 is driven to rotate downward to match the inclined plate 33, so that the garbage in the storage tank 15 can move to the collection box 34, and thus all the garbage in the storage tank 15 can enter the collection box 34, which is convenient for subsequent synchronous processing.

[0041] The locking assembly comprises an L-shaped rotating rod 35 fixedly connected with the rotating shaft of the discharge plate 31. The L-shaped rotating rod 35 is slidably connected with the limiting frame 32. The limiting frame 32 is slidably connected with a hinged seat 36. A hinged rod 37 is rotatably connected between the hinged seat 36 and the L-shaped rotating rod 35. The hinged seat 36 is threadedly connected with a first threaded rod 38. The first threaded rod 38 is provided at the lower end with a first gear 39. The bottom of the buoyancy tank 1 is rotatably connected with a gear ring 40 engaged with the first gear 39. The gear ring 40 penetrates the buoyancy tank 1 and is fixedly provided with a hand ring 41. In the initial state, the discharge plate 31 is sealingly connected with the rectangular groove 30, so that the storage tank 15 can store garbage. At this time, the hinged seat 36 and the L-shaped rotating rod 35 are located at the uppermost side of the sliding stroke. At this time, the first threaded rod 38 locks the hinged seat 36 at this position. When the discharge plate 31 needs to be opened, the hand ring 41 is rotated to drive the gear ring 40 to drive the first gear 39 and the first threaded rod 38 to rotate, so that the hinged seat 36 threadedly connected with the first threaded rod 38 moves downward. Thus, the L-shaped rotating rod 35 is driven to rotate downward by the hinged rod 37 to drive the discharge plate 31 to rotate and leak out of the rectangular groove 30. In order to improve the stability of the gear ring 40, the existing locking method can be used to connect the gear ring 40 with the buoyancy tank 1, such as using bolts to connect the hand ring 41 with the buoyancy tank 1, so that the meshing teeth of the gear ring 40 lock the first gear 39.

[0042] The inside of the storage tank 15 is provided with an inclined surface matched with the discharging plate 31, and a water quality detection sensor 42 is installed in the one-way hole. The inclined surface can facilitate the sliding of garbage downward, and the water quality detection sensor 42 is connected to a terminal outside to receive the water quality detection signal of the water quality detection sensor 42, so that the water quality environment of the water area can be analyzed through the terminal, and further, the next step can be taken conveniently;

[0043] The water quality detection sensor 42 here has several working states:

[0044] 1. When collecting garbage on the water surface, the water solution near the water surface will enter the inside of the collecting tank body 12, and then enter the lower one-way communication groove 17. Since the lower one-way communication groove 17 is in communication with the one-way hole, the water that enters the inside of the lower one-way communication groove 17 first enters the inside of the one-way hole for detection, and the subsequent water enters the two-way pump 19 through the lower one-way communication groove 17. During continuous pumping, the water solution in the one-way hole changes, and then the change of the water quality is detected by the water quality detection sensor 42;

[0045] 2. When the garbage mixed water solution enters the inside of the storage tank 15, the residual qualitative solution in the inside of the storage tank 15 is detected by the water quality detection sensor 42 when the solution in the inside of the storage tank 15 is pumped by the two-way pump 19. The water quality of the water solution detected here does not change, and thus the water quality of the water solution brought by the garbage is checked;

[0046] 3. When oxygen is supplied through the landscape water spraying device 10, the solution at the bottom of the water area is pumped into the inside of the lower one-way communication groove 17 through the water pipe 13, but it cannot enter the inside of the collecting tank body 12 due to the restriction of the one-way valve. The solution in the inside of the lower one-way communication groove 17 enters the inside of the one-way hole, and thus the solution at the bottom of the water area is detected.

[0047] A hollow cylinder 45 is fixedly installed in the middle of the collecting box 34 and is in sealed connection with the lower side output end of the two-way pump 19. A plurality of water pumping channels 43 are formed in the lower part of the collecting box 34 and are in communication with the hollow cylinder 45. A one-way water inlet valve 44 is installed at the bottom of the collecting box 34 and is in communication with the water pumping channels 43. When the water solution full of air is used to supplement oxygen in the water body, the water solution can be dispersed in all directions through the uniformly installed water pumping channels 43, which is more conducive to the reaction absorption of the higher closed water area. The one-way water inlet valve 44 can make the water solution in the inside of the collecting box 34 enter the water pumping channels 43 and be discharged.

[0048] The reciprocating mechanism includes a ring 50 in sealed rotary connection with the water pipe 13. The ring 50 is fixedly installed with inclined paddles 51 fixedly connected with each other. The ring 50 is fixedly connected with an outer gear ring 52. A plurality of second gears 53 are rotatably connected in the inside of the collecting tank body 12 and are in transmission connection with the outer gear ring 52. The plurality of second gears 53 are each installed with a connecting rod assembly in transmission connection with the push rod 23.

[0049] The connecting rod assembly comprises a rotating rod 54 fixedly connected with the second gear 53, and the distal end of the rotating rod 54 is rotatably connected with a connecting rod 55, and the other end of the connecting rod 55 is rotatably connected with the push rod 23.

[0050] When the bidirectional pump 19 pumps water, the water solution passing through the lower one-way communication groove 17 can act on the surface of the inclined paddle 51, and then the inclined paddle 51 drives the rotating ring 50 and the outer gear ring 52 to rotate. Since the outer gear ring 52 is engaged with a plurality of second gears 53, the outer gear ring 52 drives the plurality of second gears 53 and the rotating rod 54 to rotate, and then the connecting rod 55 is driven to rotate by the rotating rod 54, and the push rod 23 and the scraping strip 22 are driven to slide forward and backward, thereby scraping the filter screen 20, so as to avoid that the garbage blocks the lower one-way communication groove 17.

[0051] The up-down moving mechanism comprises transmission gears 56 rotatably connected with the buoyancy tank 1 in a symmetrical manner, and the two transmission gears 56 are jointly engaged with an inner gear ring 57 rotatably connected inside the buoyancy tank 1. The buoyancy tank 1 is rotatably connected with a drive gear 58 engaged with the inner gear ring 57. The collecting groove body 12 is provided at the lower end with a band brake motor 59 in transmission connection with the drive gear 58. The lower ends of the plurality of baffles 14 are fixedly provided with moving plates 60 fixedly connected at the other ends. The upper ends of the two transmission gears 56 are provided with second threaded rods 61 in threaded connection with the moving plates 60.

[0052] When the band brake motor 59 works, the drive gear 58 is driven to rotate, and then the inner gear ring 57 is driven to rotate, and the transmission gears 56 and the second threaded rods 61 are driven to rotate by the rotating inner gear ring 57. Since the moving plates 60 can only slide up and down, the moving plates 60 in threaded connection with the second threaded rods 61 are moved up and down, thereby controlling the opening and closing of the openings of the baffles 14. In addition, the moving plates 60 are slidably connected with a plurality of slide rods, which can improve the stability of the moving plates 60.

[0053] The above embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought of the present application should be covered by the claims of the present application.
