Description

Technical Field

[0001] The invention relates to the technical field of water body restoration, in particular to a water body ecological restoration device for gardens. Background Art

[0002] A garden is a natural environment and recreational area created within a certain geographical area by using engineering technology and artistic means, through transforming the terrain (or further building mountains, stacking stones, and managing water), planting flowers and trees, creating buildings, and arranging garden paths. It cleverly combines natural beauty with artificial beauty, and has multiple functions such as viewing, leisure, and cultural inheritance. It is a space for people to get close to nature, relax, and feel the aesthetic conception. In order to maintain a better ecological environment in the garden, it is necessary to repair the bad ecological environment. Among them, the repair of waterways is the top priority in the entire ecological environment. With the massive destruction of the environment by humans, the ecological environment of waterways has become extremely bad, and the water body is seriously polluted and urgently needs to be repaired. In order to repair the water body, a mixture of physical blocking waste and chemical drugs is generally used to achieve water management, that is, using a blocking net to block the waste and then collect it, but the water body height in the ecological environment will increase with the arrival of rain and flood season, but the height of the blocking net currently used cannot be changed. When the water body height changes, it cannot effectively block the waste, and its applicability is reduced.

[0003] When performing physical blocking, it relies on a blocking net with permeable holes to block the water body, so that water can pass through the blocking net, but waste cannot pass through. However, when the water height increases, water can pass through the top of the blocking net and it is impossible to effectively block the waste. At the same time, the blocking net is greatly affected by the buoyancy of the water body and is prone to floating. At this time, the cross-sectional area of ​​the blocking net is small, and at the same time, effective blocking can be achieved and the waste needs to be manually salvaged, which increases the workload to a certain extent.

[0010] Preferably, guide rods are respectively provided on both sides of the scraper, and connecting plates are respectively fixedly connected to both ends of the two guide rods, and both ends of the connecting plates are fixedly connected to the inner wall of the lower net body, and the outer wall of the pull rope passes through the connecting plate to form an L-shaped structure, and extrusion columns are respectively fixedly connected to both sides of the scraper.

[0011] Preferably, the cleaning assembly further comprises two sewage discharge chambers, which are respectively located on both sides of the lower net body, and the bottom ends of the sewage discharge chambers are fixedly connected to the upper surface of the river bank.

[0012] Preferably, a T-shaped limiting member is fixedly provided on the upper side of the inner wall of the sewage discharge chamber.

[0013] Preferably, the cleaning assembly also includes two side baffles, which are respectively installed at both ends of the lower net body, and raised layers are fixedly provided on both sides of the top of the side baffles, and the lower surface of the raised layer is fixedly connected with a spring telescopic rod, and the bottom end of the spring telescopic rod is embedded and fixed in the upper surface of the lower net body.

[0014] Preferably, the side baffle includes a sliding end and a rotating end, the outer wall of the sliding end is slidably connected to the inner wall of the lower mesh body, the sliding end and the opposite end of the rotating end are rotatably connected via an axis, a blocking plate is provided on the upper side of the rotating end, and the outer wall of the blocking plate is fixedly connected to the upper side wall of the lower mesh body.

[0015] Preferably, the bottom sides of both ends of the lower net body are rotatably connected to guide plates via torsion spring shafts, and the guide plates are configured to be U-shaped.

[0016] Working principle: When in use, the lower net body is floated on the water surface through the buoyancy layer. The floating garbage on the garden water surface enters the lower net body through the gap driven by the water flow and is intercepted by the lower net body. When the liquid level of the river water changes, the lower net body rises and falls along the support rod synchronously according to the rise and fall of the liquid level under the buoyancy of the buoyancy layer, so that the floating garbage on the garden water surface can always be intercepted, meeting the interception requirements of different water body heights.

[0017] When it is necessary to clean up the garbage, the electric push rod is extended to drive the electromagnet to descend and press against the connecting seat, the electromagnet is operated and adsorbs the connecting seat, thereby connecting the lower net body to the electric push rod, and then the electric push rod is contracted to pull the lower net body upward and above the water surface, so that the garbage is separated from the water. After a period of drying, the garbage in the lower net body can be cleaned by the cleaning component. When a ship needs to pass on the water surface, the electric push rod is extended to press against the connecting seat, thereby pushing the lower net body into the water, so that the ship can pass through the protective net smoothly, and when the electric push rod descends, it drives the net body to descend, so that the upper net body and the lower net body are closed, thereby preventing the garbage inside the net body from flowing out.

[0018] When the cleaning component is cleaning, the electric push rod pulls up the lower net body until the inner bottom wall of the lower net body is higher than the inner bottom wall of the sewage chamber. The guide plate is pressed against the sewage chamber by the torsion force of the torsion spring shaft, thereby blocking the gap between the sewage chamber and the side opening of the lower net body, so that the garbage can enter the interior of the sewage chamber along the guide plate when it is discharged, thereby reducing the falling of garbage when it is discharged, and the two winches are operated in turn to reel in the line. The pull rope connected to the winch reel is pulled to rotate the scraper, and then the scraper slides to push the garbage inside the lower net body into the sewage chamber. By placing a garbage bin under the sewage chamber, the garbage can be collected, thereby achieving the effect of automatic cleaning and collection of garbage, and reducing the pollution of garden water bodies by floating garbage.

[0019] The elastic supporting force applied by the spring telescopic rod makes the top end of the rotating end higher than the blocking plate, so that the rotating end is limited by the blocking plate, so that the side baffle plate remains vertical, so that the two ends of the lower net body can be intercepted to prevent garbage from flowing out from the two ends of the lower net body. When the lower net body for cleaning garbage is connected to the sewage chamber, the upward moving side baffle plate is blocked by the limiting member, so that the rotating end drops below the blocking plate. When the scraper drives the garbage to move, the rotating end can be pushed to rotate upward from the inside of the sewage chamber, thereby opening the lower net body, so that the garbage can fall into the sewage chamber.

[0020] The present invention provides a water ecological restoration device for gardens, which has the following beneficial effects:

[0021] 1. The present invention uses the buoyancy of the buoyancy layer to make the lower net body rise and fall synchronously according to the rise and fall of the liquid level, so that floating garbage on the garden water surface can still be intercepted when the water level changes, achieving the interception requirements of adapting to different water body heights.

[0022] 2. The present invention can push the lower net body into the water through the cooperation of the electric push rod and the electromagnet, so that the boat can pass through the protective net smoothly, and can also lift the lower net plate upward to make the garbage out of the water, which is convenient for the subsequent discharge of the garbage collected in the lower net plate.

[0023] 3. The present invention pushes the garbage inside the lower net body into the sewage chamber by sliding the scraper. By placing a garbage bin under the sewage chamber, the garbage can be collected, achieving the effect of automatic cleaning and garbage collection, and reducing the pollution of floating garbage to the garden water body.

[0024] 4. The present invention prevents garbage from overflowing from the protective net when the protective net is immersed in water for ships to pass through and when the lower net is raised for cleaning, through the cooperation of the lower net body, the upper net body and the side baffles, thereby improving the garbage collection effect.

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings 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.

[0035] Please see attached Figure 1 -Attached Figure 4The embodiment of the present invention provides a water ecological restoration device for gardens, including a river bank 1, a protective net 2 is installed above the river bank 1, the protective net 2 includes a lower net body 21, the lower net body 21 is set to be U-shaped, a notch 3 is opened on one side of the lower net body 21, and support rods 5 are respectively penetrated at the four corners of the lower net body 21, the support rods 5 are made of anti-corrosion material, the upper surfaces of the two support rods 5 are fixedly connected with mounting seats 6, the bottom ends of the support rods 5 are fixedly connected to the inner lower wall of the river bank 1, and a height adjustment component 4 is installed on the surface of the protective net 2. The height adjustment component 4 includes a plurality of buoyancy blocks 41 and an electric push rod 42. The buoyancy blocks 41 are fixedly installed on the lower surface of the lower net body 21, and the top ends of both sides of the lower net body 21 are respectively fixedly connected with connecting seats 7 made of ferromagnetic material. The outer wall of the electric push rod 42 is fixedly connected to the upper surface of the mounting seat 6, and the driving end of the electric push rod 42 penetrates the mounting seat 6 and is fixedly connected with a waterproof electromagnet 43.

[0036] Specifically, by setting multiple groups of protective nets 2 on the river channel of the garden, a multi-layer interception is formed, and the protective nets 2 are limited by the support rods 5 so that the protective nets 2 can be vertically lifted and lowered along the support rods 5. The gaps 3 are used to allow floating garbage to enter the lower net body 21, and the buoyancy blocks 41 are used to provide buoyancy support for the lower net body 21, so that the horizontal center line of the lower net body 21 is close to the water surface, so that the lower area of ​​the lower net body 21 is immersed in water for interception, and the lower net body 21 can adaptively adjust its height according to the increase in water level, so that the lower net body 21 can always float on the water surface for interception, thereby improving the interception effect of floating garbage. The electric push rod 42 is telescopically used to adjust the height of the electromagnet 43. When the electromagnet 43 descends, it can push the lower net body 21 to immerse in water, which is convenient for ships on the water surface to pass through, and the electromagnet 43 descends to adsorb the connecting seat 7, and after the electric push rod 42 contracts and drives the electromagnet 43 to rise, the lower net body 21 rises above the water surface, so that the garbage can be cleaned up later.

[0037] Please see attached Figure 4 An L-shaped upper net body 22 is installed above the lower net body 21. The height adjustment assembly 4 also includes a connecting rod 44. The bottom end of the connecting rod 44 is fixedly connected to the upper surface of the upper net body 22. The top end of the connecting rod 44 is fixedly connected to an L-shaped connecting piece 45. The driving end of the electric push rod 42 passes through the connecting piece 45, and the driving end of the electric push rod 42 is fixedly connected to the inner wall of the connecting piece 45.

[0038] Specifically, when the electric push rod 42 contracts, the height of the upper net body 22 is raised through the connecting piece 45 and the connecting rod 44, thereby opening the gap 3. When the lower net body 21 needs to be immersed in water, the electric push rod 42 extends to drive the upper net body 22 to descend and insert into the inside of the gap 3, so that the upper net body 22 and the lower net body 21 are closed. When the protective net 2 is immersed in water, the floating garbage flowing upward is intercepted, thereby preventing the garbage from overflowing the protective net 2, and when the lower net body 21 is lifted upward, the garbage is prevented from falling from the gap 3.

[0039] Please see attached Figure 4 The height adjustment assembly 4 also includes a U-shaped guide frame 46, the inner wall of the guide frame 46 is slidably connected to the outer wall of the upper net body 22, the bottom end of the guide frame 46 is fixedly connected to the outer wall of the lower net body 21, and the top end of the guide frame 46 passes through the connecting piece 45.

[0040] Specifically, the guide frame 46 is used to guide the upper net body 22 so that the upper net body 22 can be accurately inserted into the notch 3 to achieve accurate docking between the upper net body 22 and the lower net body 21 .

[0041] Please see attached Figure 1 -Attached Figure 3 The protective net 2 is made of a stainless steel metal frame, so that the protective net 2 is not easy to rust when immersed in water. A plurality of installation openings are opened on the surface of the metal frame, and a tensioned rope net of corresponding size is fixedly arranged in the installation opening. The top end of the support rod 5 is fixedly connected to the support frame 8, and the bottom end of the support frame 8 is fixedly installed on the river bank 1.

[0042] Specifically, the metal frame is used to improve the overall strength of the protection net 2 , the rope net is used to reduce the weight and intercept garbage, and the support frame 8 is used to support the top end of the support rod 5 to improve the stability of the support rod 5 .

[0043] Please see attached Figure 5 A cleaning assembly 9 is installed on the river bank 1, the mounting seat 6 and the lower net body 21. The cleaning assembly 9 includes a scraper 91. The outer wall of the scraper 91 is slidably connected to the inner wall of the lower net body 21. Pull ropes 92 are fixedly connected to both sides of the scraper 91. The other end of the pull rope 92 passes through the mounting seat 6 and is fixedly connected to a winch 93. One end of the pull rope 92 is wound around and fixed on the drum of the winch 93. The bottom end of the winch 93 is fixedly mounted on the upper surface of the mounting seat 6. Push protrusions are respectively provided on both sides of the scraper 91. The top of the push protrusion is lower than the connecting plate 95. The push protrusion is used to pass through the connecting plate 95 to assist in pushing the garbage in the two end areas of the lower net body 21, thereby reducing the residual garbage at both ends of the lower net body 21.

[0044] Specifically, in the interception room, the two groups of winches 93 both pay out the wires to facilitate the lifting and lowering of the lower net body 21. When the lower net body 21 is lifted up for cleaning, the two groups of winches 93 reel in the wires in turn. When one of the groups of winches 93 reels in the pull rope 92, the scraper 91 is pulled to slide, thereby pushing out the garbage inside the lower net body 21. Then the winch 93 pays out the wires again, and when the other group of winches 93 reels in the pull rope 92, the scraper 91 is pulled to slide in the opposite direction, thereby relatively comprehensively cleaning out the garbage inside the lower net body 21 and reducing the residual garbage.

[0045] Please see attached Figure 5 -Attached Figure 6 Guide rods 94 are respectively provided on both sides of the scraper 91, and connecting plates 95 are respectively fixedly connected at both ends of the two guide rods 94. The two ends of the connecting plates 95 are fixedly connected to the inner wall of the lower net body 21. The outer wall of the pull rope 92 passes through the connecting plate 95 to form an L-shaped structure, and extrusion columns 11 are respectively fixedly connected on both sides of the scraper 91.

[0046] Specifically, the guide rod 94 is used to guide and support the scraper 91 , and the connecting plate 95 is used to change the force direction of the pull rope 92 and fix the guide rod 94 .

[0047] Please see attached Figure 5 The cleaning assembly 9 also includes two drainage chambers 96, which are respectively located on both sides of the lower net body 21. The bottom ends of the drainage chambers 96 are fixedly connected to the upper surface of the river bank 1, and the inner bottom wall of the drainage chamber 96 is provided with an inclined surface for allowing garbage to slide out of the drainage chamber 96.

[0048] Specifically, the sewage chamber 96 is used to connect the two ends of the lower net body 21, so that the garbage enters the interior of the sewage chamber 96 when it is pushed out of the lower net body 21. A garbage bin is placed below the sewage chamber 96 to collect the garbage.

[0049] Please see attached Figure 7 The cleaning component 9 also includes two side baffles 98, which are respectively installed at the two ends of the lower net body 21. A raised layer is fixedly provided on both sides of the top of the side baffle 98, and a spring telescopic rod 99 is fixedly connected to the lower surface of the raised layer. The bottom end of the spring telescopic rod 99 is embedded and fixed on the upper surface of the lower net body 21.

[0050] Specifically, the side baffle 98 is limited by the spring telescopic rod 99 so that the side baffle 98 blocks the side end openings of the lower net body 21 to prevent garbage from flowing out from the openings at both ends of the lower net body 21 .

[0051] Please see attached Figure 8The side baffle 98 includes a sliding end 981 and a rotating end 982. The outer wall of the sliding end 981 is slidably connected to the inner wall of the lower mesh body 21. The sliding end 981 and the opposite end of the rotating end 982 are rotatably connected through an axis. A blocking plate 10 is provided on the upper side of the rotating end 982. The outer wall of the blocking plate 10 is fixedly connected to the upper side wall of the lower mesh body 21. A T-shaped limiter 97 is fixedly provided on the upper side of the inner wall of the sewage discharge chamber 96. Extrusion columns 11 are fixedly connected on both sides of the scraper 91.

[0052] Specifically, the sliding end 981 is used to slide with the lower net body 21 to improve stability. The height of the rotating end 982 is lifted by the spring telescopic rod 99, so that the rotation connection between the sliding end 981 and the rotating end 982 is higher than the blocking plate 10, so that the rotating end 982 is vertically limited under the cooperation of the blocking plate 10 and the lower net body 21, so that the side baffle 98 at this time remains vertical to block the side opening of the lower net body 21. When the lower net body 21 rises to connect with the sewage chamber 96, the gradually rising sliding end 981 is limited by the limiting member 97, so that the sliding end 981 and the rotating end 982 move downward until the rotation connection between the sliding end 981 and the rotating end 982 is lower than the blocking plate 10. At this time, the rotating end 982 can rotate upward under the thrust of the garbage pushed by the scraper 91 and the extrusion column 11 when it moves closer, thereby opening the side opening of the lower net body 21, so that the garbage can fall into the sewage chamber 96.

[0053] Please see attached Figure 7 The bottom sides of both ends of the lower net body 21 are rotatably connected to the guide plate 12 through the torsion spring shaft. The guide plate 12 is set to be U-shaped, and the lower end of the guide plate 12 is provided with a chamfered surface for fitting the outer wall of the sewage chamber 96 when rotating and tilting. The elastic force of the spring telescopic rod 99 is greater than the torsion of the torsion spring shaft.

[0054] Specifically, the guide plate 12 is pressed against the rotating end 982 by the torsion force of the torsion spring shaft. When the rotating end 982 rotates to open the side opening of the lower net body 21, the guide plate 12 is pressed against the sewage chamber 96 by the torsion force of the torsion spring shaft, thereby blocking the gap between the sewage chamber 96 and the side opening of the lower net body 21, so that the garbage can enter the interior of the sewage chamber 96 along the guide plate 12 when being discharged, thereby reducing the falling of garbage when being discharged.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
