[0016] In order to facilitate understanding, the core principle of the present scheme is described:
[0017] I. Reduce cost, facilitate maintenance
[0018] Plant floating bed is usually floating on the water surface, and various plants are planted thereon to purify the water. However, as the plants grow, the weight of the plant floating bed increases, which causes the plant floating bed to sink, and then the root system of the plant is completely submerged in water, affecting the respiration and growth of the plant. Therefore, some current designs use some electrically driven telescopic structures (such as some electric motors) to adjust the sinking position of the plant floating bed, which is very high in cost (the electric motor is easy to corrode and damage), and is very difficult to maintain.
[0019] In the scheme, the auxiliary cavity is arranged on the floating base body, the auxiliary cavity has an inner cavity, water is arranged in the inner cavity, and the auxiliary cavity is connected with the pump and the water pipeline; if the water in the auxiliary cavity is pumped away, the weight of the plant floating bed is reduced, if the water is pumped into the inner cavity of the auxiliary cavity, the weight of the floating bed is increased, the pump and the cable are arranged on the shore (some rain shelters are arranged), so that corrosion can be avoided (compared with arranging the motor in water), and maintenance is also convenient.
[0020] That is, the expansion and contraction of the expansion and contraction mechanism is adjusted by the buoyancy and weight of the auxiliary cavity, and the expansion and contraction mechanism also plays a role in avoiding the plant floating bed from floating everywhere.
[0021] Two, convenient installation
[0022] Some current plant floating beds are rectangular plastic shells with inner cavities spliced together, the rectangular plastic shells have upper and lower through holes, planting pots are arranged in the through holes, and small holes are formed in the bottom of the planting pots.
[0023] In the scheme, the auxiliary cavity is divided into a lower barrel and an upper cover, the upper neck of the lower barrel passes through the placement hole and is directly screwed with the upper cover, so that installation is very simple and convenient, and any structure of the existing rectangular plastic shell does not need to be improved.
[0024] In the scheme, the expansion and contraction mechanism is fixedly arranged at the placement hole through the radial cross rod and the nut part of the fixing cylinder, so that installation is very convenient, and the structure of the existing rectangular plastic shell does not need to be changed.
[0025] The utility model has the following advantages: the sinking and floating of the plant floating bed is controlled by the water supplementing / withdrawing mode of the auxiliary cavity, the cost is low, and maintenance is convenient; the structure of the existing plant floating bed does not need to be changed, and installation is directly and conveniently carried out.

DETAILED DESCRIPTION
[0037] The utility model will be further described below in combination with the drawings, but the protection scope of the utility model is not limited to the following.
[0038] It should be noted that the directions or positional relationships indicated by "left", "right" and the like are based on the directions or positional relationships shown in the drawings, or the directions or positional relationships in which the utility model product is usually placed during use, or the directions or positional relationships commonly understood by those skilled in the art. Such terms are only used for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.
[0039] It should be noted that the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other without conflict.
[0040] It should be noted that some wetland plant floating beds currently use similar Figure 10The plurality of plastic units 11 are spliced as shown, and the plastic unit 11 itself is a plastic shell with an inner cavity, which can float when placed on the water surface. There are a plurality of up-and-down through connecting holes 14 at the edge of the plastic unit 11, and an anti-skid groove 1401 is opened on the surface of the plastic unit 11 at the connecting hole 14. When splicing the plurality of plastic units 11, the rope is passed through the connecting hole 14 and around the anti-skid groove 1401. Furthermore, there is an up-and-down through cavity 12 in the middle of the plastic unit 11, and a plastic planting barrel is placed at the through cavity 12. The bottom of the plastic planting barrel is provided with a small hole, and the plastic planting barrel has a flange that serves as a limiting function. When the wetland plant floating bed is placed on the water surface, the plastic planting barrel with plants is placed in the placement hole 12, and the roots of the plants grow through the small hole in the bottom of the plastic planting barrel into the water, thereby purifying the polluted water.
[0041] The problem is that as the plants grow, the weight of the entire wetland plant floating bed gradually increases, causing the wetland plant floating bed to gradually submerge in the water, allowing the plant roots to be completely submerged in the water, affecting the growth of the plants, and even causing the roots to rot. Currently, there are some ways to use electric lifting to raise the wetland plant floating bed, but this way is too expensive and is not conducive to maintenance.
[0042] The present scheme discloses a lifting structure for a wetland plant floating bed, which adjusts the position of the plant floating bed in the water by adjusting the weight of the plant floating bed under the action of buoyancy, which not only has low cost, but also is easy to maintain (of course, the present scheme is not limited to plant floating beds, but can also be used for other water equipment that needs to adjust the position).
[0043] Specifically, as shown in Figure 1 and Figure 2 The present embodiment provides a lifting structure for a wetland plant floating bed, which is placed on the water surface and includes a floating base 10, an auxiliary cavity 20, and a telescopic mechanism 30.
[0044] The floating base 10 is provided with the auxiliary cavity 20, and the inner cavity of the auxiliary cavity 20 is connected with a water pipeline. The water pipeline is connected with a water pump on the shore, and the pipeline of the water pump is also connected with water in the wetland.
[0045] The floating base 10 is also provided with the telescopic mechanism 30, which is inserted into the soil at the bottom of the water.
[0046] When it is needed to place the plant floating bed at a certain position in the water, the telescopic mechanism 30 is inserted into the water.
[0047] When working, at the initial planting, the weight of the whole plant floating bed is not enough because the plants have not grown, so water needs to be pumped into each auxiliary cavity 20 to increase the weight of the plant floating bed and make the bottom of the plastic planting barrel immersed in water; as the plants grow, after a period of time, the staff finds that the plant floating bed sinks badly, so a part of water in the auxiliary cavity 20 is pumped out to reduce the weight of the whole plant floating bed and make the plant floating bed float up.
[0048] The advantage is that the pump can be arranged at the shore, and the cable and the like can not be immersed in water, so that the pump, the cable and the like can be maintained on the shore, which is very convenient; and the cost of manufacturing the plant floating bed is very low except for the pump (the pump can be repeatedly used).
[0049] In the embodiment, a plurality of auxiliary cavities 20 are arranged at intervals on the floating base 10, and a plurality of telescopic mechanisms 30 are arranged at intervals on the floating base 10.
[0050] The placement position and structure of the auxiliary cavity 20 will be further described below.
[0051] As shown in Figures 3-6 , the auxiliary cavities 20 are arranged at the placement holes 12 of some plastic units 11.
[0052] The auxiliary cavity 20 includes a lower barrel 21 and an upper cover 22, the lower barrel 21 is small at the top and large at the bottom, and the upper part of the lower barrel 21 is in the shape of a neck; during installation, the neck of the lower barrel 21 is passed through the placement hole 12 from bottom to top, and then the upper cover 22 is screwed on, so that the upper cover 22 is threadedly connected with the neck of the lower barrel 21, the upper cover 22 and the lower barrel 21 clamp and fix the plastic unit 11, and the installation is very convenient.
[0053] Further, the lower barrel 21 has a water hole 2101 near the bottom thereof, and the water hole 2102 is connected with the water pipe line.
[0054] Further, the upper cover 22 is a shell with an inner cavity, the upper cover 11 has an air hole A2201 at the inner top wall thereof, and the upper cover 22 has an air hole B2202 at the outer side wall thereof near the lower middle part, the lower barrel 21 is connected with the outside through the air hole A2201, the inner cavity of the upper cover 22 and the air hole B2202, so that the outside air can enter the auxiliary cavity 20 when water is pumped into or pumped out of the auxiliary cavity 20.
[0055] The position and structure of the telescopic mechanism 30 will be further described below.
[0056] Specifically, referring to Figures 7-9 , the telescopic mechanisms 30 are also arranged at the placement holes 12 of some plastic units 11.
[0057] The telescopic mechanism 30 comprises an outer cylinder 31, an inner rod 32 and a fixed cylinder 33. The lower part of the fixed cylinder 33 has a radial crossbar 3301, and the upper part is screwed with a nut part 3302 from the placing hole 12, and the plastic unit 11 is clamped through the radial crossbar 3301 and the nut part 3302. In addition, the outer cylinder 31 is welded and fixed in the fixed cylinder 33 through the radial crossbar 3301, and the outer cylinder 31 is vertically arranged, and the inner rod 32 is inserted in the outer cylinder 31. When the plant floating bed adjusts the position, the inner rod 32 slides up and down in the outer cylinder 31, and the plant floating bed can be prevented from moving in the horizontal plane.
[0058] A plug hole is opened along the radial direction of the cross section of the lower part of the outer cylinder 31, and the inner rod 32 has a sliding slot 3201 penetrating through it; when the outer cylinder 31 is inserted into the inner rod 32, the cross pin 3101 is inserted into the sliding slot 3201 through the plug hole. When the outer cylinder 31 slides up and down along the inner rod 31, the cross pin 3101 reaches the upper limit position and the lower limit position of the sliding slot 3201, forming an upper and lower limit structure.
[0059] The above embodiments only express the preferred embodiments, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model.
