Description

Technical Field

[0001] This utility model relates to the field of constructed wetland technology, and in particular to a landscape water circulation and purification constructed wetland. Background Technology

[0002] Constructed wetlands are artificially built and controlled wetlands similar to marshes. Wastewater and sludge are systematically distributed onto these artificially constructed wetlands. As the wastewater and sludge flow in a certain direction, the technology mainly utilizes the physical, chemical, and biological synergistic effects of soil, artificial media, plants, and microorganisms to treat the wastewater and sludge.

[0003] Chinese utility model patent CN213202739U discloses an artificial wetland for landscape water circulation and purification, which includes an artificial wetland with a landscape pool at the upper end of the artificial wetland and the landscape pool extending into the interior of the artificial wetland. A water storage tank is set in the artificial wetland. Several overflow pipes are fixedly connected to the left, right, front and rear walls of the landscape pool, and the end of the overflow pipe away from the landscape pool extends into the artificial wetland.

[0004] During the use of the above-mentioned artificial wetland with landscape water circulation and purification, some of the sewage on the surface of the artificial wetland will flow directly into the landscape pool, and floating objects or debris in the sewage will also flow into the landscape pool with the water flow, increasing the probability of the overflow pipe in the landscape pool being blocked. Utility Model Content

[0005] To address the aforementioned problems, this invention provides an artificial wetland for landscape water circulation and purification.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an artificial wetland for landscape water circulation and purification, comprising a wetland body for planting pollution-tolerant plants and filtering sewage, and a water storage mechanism set on the wetland body. The top of the wetland body is provided with multiple through grooves, and an annular water pool is fixed in the through grooves. Multiple overflow holes communicating with the inside of the wetland body are provided on the inner side wall of the annular water pool. The top of the annular water pool is provided with an installation groove, and an installation frame is detachably connected in the installation groove. An installation through hole is provided through the top of the installation frame, and a filter screen is fixed in the installation through hole. A positioning mechanism for positioning the installation frame is provided on the installation frame. The number of through grooves, the number of annular water pools, the number of installation frames, and the number of positioning mechanisms are all equal and their positions correspond one-to-one.

[0007] By adopting the above technical solution, during the use of the device, the sewage on the top of the wetland body will flow into the circular pool through the mesh of the filter screen, while floating objects or debris in the sewage will be blocked by the filter screen, reducing the probability of the overflow hole in the landscape pool becoming clogged.

[0008] Furthermore, the mounting frame is provided with a cavity, and the positioning mechanism includes a positioning component. The positioning component is provided in two sets and is symmetrically arranged about the middle of the mounting frame. The positioning component includes an insert that is slidably disposed in the cavity, a connecting block fixed on the insert, a slider fixed to the bottom of the connecting block, and a spring fixed between the two sets of sliders and in an elongated state. The insert passes through the mounting frame and is slidably connected. The side wall of the annular water tank is provided with a socket for inserting and engaging with the insert. The number of inserts is equal to the number of sockets and their positions correspond one-to-one. The positioning mechanism also includes a moving component for driving the two sets of connecting blocks to move.

[0009] By adopting the above technical solution, the moving component drives the two sets of connecting blocks to move towards each other, so that the inserts connected to the two sets of connecting blocks and the inserts connected to the two sets of connecting blocks move towards each other until the water tank and the socket are separated. At this time, the mounting bracket can be taken out from the mounting slot. The stability of the mounting bracket when connected to the mounting slot is improved by limiting the insertion of the inserts and the socket.

[0010] Furthermore, the movable component includes a threaded post that passes through the top of the mounting frame and is threadedly connected, a frustum block fixed to the bottom of the threaded post, and a handle fixed to the top of the threaded post. The distance between the sidewalls of the two sets of connecting blocks that are close to each other gradually decreases from top to bottom. The outer diameter of the frustum block gradually decreases from top to bottom. The sidewalls of the frustum block abut against the sidewalls of the two sets of connecting blocks that are close to each other.

[0011] By adopting the above technical solution, rotating the handle and driving the threaded column to rotate, the threaded column is threadedly connected to the mounting bracket, causing the frustum block connected to the threaded column to rise. As the distance between the side walls of the two sets of connecting blocks gradually decreases from top to bottom, the outer diameter of the frustum block gradually decreases from top to bottom, and the spring gradually contracts, thereby causing the two sets of connecting blocks to move closer to each other, thus achieving the purpose of separating the insert from the socket.

[0012] Furthermore, the water storage mechanism includes a water storage component, which includes a water storage tank fixed to the bottom of the wetland body and made of reinforced concrete, and a water-absorbing cotton that is installed through and fixed to the top of the water storage tank. The top of the water-absorbing cotton is attached to the bottom of the wetland body. The water storage mechanism also includes a drainage component for pumping water out of the water storage tank.

[0013] By adopting the above technical solution, the water inside the wetland can be drawn into the water storage tank through the absorbent cotton, which avoids the problem of blockage compared with the existing technology that uses pipes.

[0014] Furthermore, the drainage assembly includes a water pump fixed to the water storage tank, an inlet pipe fixed and connected to the input end of the water pump, a drain pipe fixed and connected to the output end of the water pump, a water supply pipe fixed and connected to the end of the drain pipe away from the water pump, and a rotating nozzle fixed to the top of the wetland body. The end of the water supply pipe away from the drain pipe is fixed and connected to the rotating nozzle, and the end of the inlet pipe away from the water pump is fixed and connected to the side wall of the water storage tank. Multiple water inlet holes are provided through the side wall of the inlet pipe.

[0015] By adopting the above technical solution, after the water pump starts working, the water in the water storage tank first enters the water inlet pipe through the water inlet hole, then is discharged by the water pump to the drain pipe, then discharged by the drain pipe to the water supply pipe, then discharged by the water supply pipe to the rotating nozzle, and finally discharged by the rotating nozzle to the top of the wetland body, thus achieving the purpose of water circulation.

[0016] Furthermore, the positioning component also includes a slide rod fixed in the cavity and slidingly engaged with both sets of sliders, and the spring is sleeved on the slide rod.

[0017] By adopting the above technical solution, the stability of the spring and slider during movement is improved.

[0018] Furthermore, a walking platform is fixed to each of the multiple annular pools.

[0019] By adopting the above technical solution, it is easy to disassemble or install the annular water tank.

[0020] Furthermore, the distance between the top of the filter screen and the inner bottom wall of the channel is less than the distance between the top of the mounting bracket and the inner bottom wall of the channel.

[0021] By adopting the above technical solution, the probability of debris falling from the top of the mounting bracket when it is lifted is reduced.

[0022] In summary, this utility model has the following beneficial effects: In this application, by setting a filter screen, the probability of overflow hole blockage in the landscape pool is reduced. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-4 As shown in the embodiment of this application, an artificial wetland for landscape water circulation and purification is disclosed, including a wetland body 1, a positioning mechanism 8, and a water storage mechanism 9. The wetland body 1 consists of, from bottom to top, the original geological soil layer, a gravel layer with a particle size of 20 to 80 mm, a sand layer, a nutrient-rich planting soil layer, a cover layer, and a viscous water storage layer. The wetland body 1 is used to plant pollution-tolerant plants and filter sewage. Multiple through-channels 2 are provided on the top of the wetland body 1, and an annular water tank 3 is fixed within each through-channel 2. Multiple overflow holes 4 communicating with the interior of the wetland body 1 are provided on the inner sidewall of the annular water tank 3, and an installation groove 5 is provided on the top of the annular water tank 3. An installation frame 6 is detachably connected to the installation groove 5. The installation frame 6 has a cavity, and an installation through hole is provided through the top of the installation frame 6. A filter screen 7 is fixed within the installation through hole. The number of through-channels 2, the number of annular water tanks 3, the number of installation frames 6, and the number of sets of positioning mechanisms 8 are all equal and their positions correspond one-to-one. During the use of the device, the sewage at the top of the wetland body 1 will flow into the annular pool 3 through the mesh of the filter screen 7, while floating objects or debris in the sewage will be blocked by the filter screen 7, reducing the probability of the overflow hole in the landscape pool becoming clogged.

[0030] A positioning mechanism 8 is mounted on the mounting frame 6 and is used to position the mounting frame 6. The positioning mechanism 8 includes a positioning component 81 and a moving component 82. The positioning component 81 includes a strip 811, a connecting block 812, a slider 813, and a spring 814. Two sets of positioning components 81 are symmetrically arranged about the center of the mounting frame 6. The strip 811 is slidably positioned within the cavity. Insertion holes 815, which engage with the strip 811, are provided through the sidewall of the annular water tank 3. The strip 811 passes through the mounting frame 6 and is slidably connected. The connecting block 812 is fixed to the strip 811. The distance between the sidewalls of the two sets of connecting blocks 812 gradually decreases from top to bottom. The slider 813 is fixed to the bottom of the connecting block 812. The spring 814 is fixed between the two sets of sliders 813 and is in an extended state. The number of strips 811 is equal to the number of insertion holes 815, and their positions correspond one-to-one. The moving component 82 drives the two sets of connecting blocks 812 to move towards each other, so that the inserts 811 connected to the two sets of connecting blocks 812 and the inserts 811 connected to the two sets of connecting blocks 812 move towards each other until the water tank 911 separates from the socket 815. At this time, the mounting bracket 6 can be taken out from the mounting groove 5. The limiting of the inserts 811 and the socket 815 improves the stability of the mounting bracket 6 when connected to the mounting groove 5.

[0031] The movable assembly 82 includes a threaded post 821, a frustum block 822, and a handle 823. The movable assembly 82 is used to drive the two sets of connecting blocks 812 to move. The threaded post 821 is threaded through and disposed at the top of the mounting bracket 6, and the frustum block 822 is fixed to the bottom of the threaded post 821. The outer diameter of the frustum block 822 gradually decreases from top to bottom, and the sidewalls of the frustum block 822 abut against the adjacent sidewalls of the two sets of connecting blocks 812. The handle 823 is fixed to the top of the threaded post 821. Rotating the handle 823 causes the threaded post 821 to rotate. Since the threaded post 821 is threadedly connected to the mounting bracket 6, the frustum block 822 connected to the threaded post 821 rises. As the distance between the side walls of the two sets of connecting blocks 812 gradually decreases from top to bottom, the outer diameter of the frustum block 822 gradually decreases from top to bottom, and the spring 814 gradually contracts, thereby causing the two sets of connecting blocks 812 to move closer to each other, thus achieving the purpose of separating the insert 811 from the socket 815.

[0032] A water storage mechanism 9 is installed on the wetland body 1, and includes a water storage component 91 and a drainage component 92. The water storage component 91 includes a water tank 911 and absorbent cotton 912. The water tank 911 is fixed to the bottom of the wetland body 1 and is constructed of reinforced concrete. The absorbent cotton 912 is installed through and fixed to the top of the water tank 911, with its top fitting against the bottom of the wetland body 1. The absorbent cotton 912 allows water from inside the wetland body 1 to be drawn into the water tank 911, eliminating the risk of blockages compared to existing technologies that use pipes.

[0033] The drainage assembly 92 is used to pump water out of the water storage tank 911. The drainage assembly 92 includes a water pump 921, an inlet pipe 922, a drain pipe 923, a delivery pipe 924, and a rotating nozzle 925. The water pump 921 is fixed to the water storage tank 911, and the inlet pipe 922 is fixed and connected to the input end of the water pump 921. The end of the inlet pipe 922 away from the water pump 921 is fixed and connected to the side wall of the water storage tank 911, and multiple inlet holes are provided through the side wall of the inlet pipe 922. The drain pipe 923 is fixed and connected to the output end of the water pump 921, and the delivery pipe 924 is fixed and connected to the end of the drain pipe 923 away from the water pump 921. The end of the delivery pipe 924 away from the drain pipe 923 is fixed and connected to the rotating nozzle 925, and the rotating nozzle 925 is fixed to the top of the wetland body 1. After the water pump 921 starts working, the water in the water storage tank 911 first enters the water inlet pipe 922 through the water inlet hole, and then is discharged by the water pump 921 to the drain pipe 923. Then it is discharged from the drain pipe 923 to the water supply pipe 924, and then from the water supply pipe 924 to the rotating nozzle 925. Finally, it is discharged from the rotating nozzle 925 to the top of the wetland body 1, thus achieving the purpose of water circulation.

[0034] The positioning assembly 81 also includes a slide rod 816, which is fixed in the cavity and slides in cooperation with two sets of sliders 813. A spring 814 is sleeved on the slide rod 816, which improves the stability of the spring 814 and the slider 813 during movement.

[0035] A walking platform 10 is fixed to multiple annular water tanks 3. This facilitates the disassembly or installation of the annular water tanks 3.

[0036] The distance between the top of the filter screen 7 and the inner bottom wall of the channel 2 is less than the distance between the top of the mounting bracket 6 and the inner bottom wall of the channel 2. This reduces the probability of debris falling from the top of the mounting bracket 6 when it is lifted.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
