[0041] Duckweed is a rapidly growing aquatic plant that is not only high in protein but also rich in various essential amino acids. Efficient duckweed production has broad ecological, economic, and social value, particularly in providing a sustainable and efficient protein source. Therefore, as duckweed plays an increasingly important role, research into related cultivation and harvesting equipment has become essential.

[0045] The inner cavity is provided with a gate 400, the gate 400 divides the inner cavity into a breeding pool 200 and a backwater pool 300, and the breeding pool 200 and the backwater pool 300 are sequentially arranged along the length direction of the floating plant breeding device. The breeding pool 200 is used for containing breeding water, and the breeding water is breeding water which is prepared with certain nutrient solution and is suitable for duckweed breeding; the gate 400 functions as a water gate and is a control end for opening and harvesting duckweed, and the water flow of the breeding pool 200 changes with the opening degree of the gate 400.

[0046] The backwater pool 300 is provided with a collection net 500, the water surface of the breeding pool 200 is higher than the position of the collection net 500, the area between the collection net 500 and the bottom of the backwater pool 300 is a backwater cavity 320, and the side, away from the backwater cavity 320, of the collection net 500 is a collection area 310; the backwater cavity 320 is used for recycling duckweed breeding water, and the collection area 310 is used for collecting duckweed.

[0047] When the duckweed is not collected, the gate 400 can be lifted to be closed, so as to separate the collection area 310 and the breeding pool 200, so that the duckweed is cultivated and grown in the breeding pool 200; when the duckweed is cultivated to a certain degree, the gate 400 can be lowered, so that the collection area 310 is communicated with the breeding pool 200, at this time, the breeding pool 200 and the backwater pool 300 form a liquid level difference, so that the duckweed in the breeding pool 200 flows to the side of the collection area 310 with the breeding water, the breeding water flows into the backwater cavity 320 through the collection area 310, and the duckweed is screened by the collection net 500 and is left in the collection area 310.

[0048] In summary, compared with the collection mode in the related art, the device of the present application can improve the collection efficiency, reduce the collection cost, and will not damage the duckweed breeding environment, thereby realizing cost reduction and efficiency increase, and ensuring a long service life of the breeding device.

[0049] Optionally, the collection net 500 comprises a filter screen 510 and a fence 520 arranged along the edge of the filter screen 510, and the fence 520 and the filter screen 510 enclose a duckweed collection groove. When the duckweed in the breeding pool 200 falls into the duckweed collection groove, it is convenient to collect and summarize.

[0050] Optionally, for the setting of the collection net 500, the collection net 500 can cover the pool water outlet of the backwater pool 300, and the height of the position of the collection net 500 is less than the initial liquid level height of the breeding water in the breeding pool 200, so that the collection area 310 is an open area to collect duckweed when the gate 400 is opened, and the present application adopts the following mode:

[0051] The floating plant cultivation device is arranged as a rectangular container, the gate 400 is arranged as a partition to separate the backwater pool 300 and the cultivation pool 200, and the pool water outlet of the backwater pool 300 and the pool water outlet of the cultivation pool 200 are flush. The collection net 500 is arranged in the backwater pool 300, the collection area 310 is a cavity surrounded by the gate 400, the collection net 500 and the enclosure member 100, and the pool water outlet of the backwater pool 300 is arranged as a collection opening of the collection area 310. Such an arrangement limits the accommodation space of the collection area 310 to prevent the duckweed from falling out of the collection area 310.

[0052] Optionally, the floating plant cultivation device further comprises a retention plate 600 arranged in the cultivation pool 200, and an extension direction of the retention plate 600 is different from a direction in which the cultivation pool 200 and the backwater pool 300 are arranged in sequence. For example, the retention plate 600 extends transversely, and the extension direction of the retention plate 600 is a width direction of the floating plant cultivation device, and the cultivation pool 200 and the backwater pool 300 are arranged in sequence along a length direction of the floating plant cultivation device. In this way, during the collection of duckweed, the retention plate 600 retains part of the duckweed in the cultivation pool 200 until the duckweed on other parts of the water surface flows to the collection net 500, so that there is always duckweed on the cultivation water body, achieving an optimal balance between duckweed collection and retention, keeping the duckweed in a high-speed growth state, realizing efficient growth of the duckweed and high utilization of resources, greatly reducing labor costs, improving water surface space utilization efficiency, and effectively filling the gaps in intelligentization, poor expansion and extension, and insufficient cost performance.

[0053] Optionally, a retention groove 610 is arranged on a side of the retention plate 600 away from the collection area 310. During the process in which the duckweed flows to the collection area 310 along the cultivation water body, the retention plate 600 more effectively accommodates part of the duckweed in the retention groove 610 to retain it for subsequent breeding.

[0054] Optionally, the retention plate 600 comprises a connecting piece 620 and a plurality of stop units 630, the stop units 630 are provided with the retention grooves 610, the stop units 630 are arranged in sequence along the extension direction of the retention plate 600, a water flow channel is formed between adjacent stop units 630, and the adjacent stop units 630 are connected by the connecting piece 620. In this way, on the one hand, the plurality of retention grooves 610 are distributed along the extension direction of the retention plate 600, so that the retained duckweed is distributed in multiple positions in the cultivation pool 200, making it easier for the duckweed to grow in subsequent cultivation. On the other hand, the arrangement of the water flow channel facilitates the flow of the cultivation water body, so that part of the duckweed can flow to the collection area 310 to be collected.

[0055] Optionally, the stop unit 630 is arranged as an arc-shaped baffle, and the storage groove 610 is an arc-shaped groove formed by a recessed area of the arc-shaped baffle, and such an arrangement can reduce the cross-sectional area of the storage plate 600, and avoid excessive extrusion of the storage plate 600 on the growth space of the duckweed in the breeding pond 200.

[0056] Optionally, a plurality of storage plates 600 are arranged along the length direction of the floating plant breeding device, so that the stored duckweed can be more uniformly distributed to all parts of the breeding water body in the breeding pond 200, and the subsequent cultivation of the duckweed is facilitated.

[0057] Optionally, the storage plate 600 is a transparent plate, so as not to hinder the irradiation of sunlight on the duckweed, and facilitate the growth of the duckweed.

[0058] Optionally, the storage plate 600 is arranged in a spaced manner with the cavity bottom of the breeding device, so as to reduce the stop of the storage plate 600 on the breeding water body, and make the breeding water body flow more freely in the breeding pond 200.

[0059] Optionally, the storage plate 600 spans the breeding pond 200, and the storage plate 600 is connected with the two opposite surrounding members 100 of the breeding device, and the two opposite surrounding members 100 are arranged in a relative manner along the width direction of the breeding device, so as to ensure the connection stability of the storage plate 600, and to reinforce the breeding pond 200 by the support force generated by the storage plate 600.

[0060] Further, for the specific connection mode of the storage plate 600 and the surrounding member 100, a fixing device 640 can be arranged at both ends of the storage plate 600. The fixing device 640 is a clamping strip, and a clamping groove for clamping the clamping strip is arranged on the surrounding member 100, so that the storage plate 600 can be clamped into the surrounding member 100, and the storage plate 600 is fixed.

[0061] Figure 3 is another structure diagram of the storage plate of the utility model, and Figure 2The difference between the standing plate 600 is that the standing plate 600 can also adopt the fixing mode of the elastic rope. Specifically, the upper and lower two parts on both sides of the stop unit 630 are perforated, the connecting piece 620 is an elastic rope, and the elastic rope penetrates a plurality of stop units 630; the fixing device 640 is a fixed frame, one side of the fixed frame extends into the culture pond 200 to connect the elastic rope, and the other side of the fixed frame extends out of the culture pond 200 to be fixed in the soil, platform or other base body for setting the culture device of the application, or is fixed on the top surface of the enclosure member 100. The purpose of such arrangement is that the side of the enclosure member 100 facing the inner cavity is attached with a waterproof film 110. Compared with the mode of clamping and fixing the standing plate 600 on the enclosure member 100, the mode of hanging the standing plate 600 by the elastic rope makes the standing plate 600 not contact the waterproof film 110, which on the one hand prevents the destruction of the waterproof film 110 and causes the loss of the culture water, and on the other hand is cost-effective and reduces the production cost.

[0062] Optionally, the standing plate 600 further comprises a stand column 650 and a longitudinal beam 660. The stand column 650 is arranged at the end of the connecting piece 620 as the elastic rope; the longitudinal beam 660 extends along the length direction of the culture pond 200; the longitudinal beam 660 is connected with the fixing device 640 and the stand column 650 respectively; the unit body composed of the connecting piece 620, the stop unit 630 and the stand column 650, and the fixing device 640 are arranged along the extension direction of the longitudinal beam 660. In this way, the number and specifications of the stop units 630 on the connecting piece 620 and the number of the unit body composed of the connecting piece 620, the stop unit 630 and the stand column 650 can be flexibly adjusted, so as to adjust the density of the stop units 630 in the culture pond 200, thereby optimizing the utilization rate of the water surface space and the nutrient distribution rate, more effectively controlling the dynamic balance of the duckweed stock and the recovery amount, and achieving the best ecological benefit.

[0063] Optionally, the buffer plate 410 is arranged on the side of the gate 400 facing the backwater pool 300. The buffer plate 410 is arranged on the top of the gate 400, and the buffer plate 410 extends towards the collection net 500 to form an included angle between the gate 400 and the buffer plate 410. This is because the duckweed may be accumulated on the outside of the gate 400, so the buffer plate 410 is made of a material that is not easy to stick to duckweed, and the duckweed falling point is dispersed.

[0064] Optionally, the floating plant cultivation device further comprises a backwater pipe 710 and a circulating pump 720, the backwater pipe 710 is communicated with the backwater cavity 320 and the cultivation pond 200 respectively, the circulating pump 720 is arranged in the backwater pipe 710, and the circulating pump 720 can be a propellerless circulating pump or a magnetic fluid water pump. When the floating algae is collected, the gate 400 is opened and the circulating pump 720 is started, at this time, the cultivation water in the backwater cavity 320 is pumped into the cultivation pond 200, so that the floating algae is continuously washed to the collection area 310 and is continuously enriched in the collection net 500, and on the other hand, the resource utilization rate of the cultivation water is improved.

[0065] Optionally, the height of the position where the backwater pipe 710 is communicated with the backwater cavity 320 is lower than the height of the position where the backwater pipe 710 is communicated with the cultivation pond 200, the backwater pipe 710 does not extend into the cultivation water of the cultivation pond 200, so as to avoid direct contact with the cultivation water in the cultivation pond 200, so that the water is pumped from the low end of the backwater cavity 320 to the high end of the cultivation pond 200 by the circulating pump 720, on the one hand, the flow performance of the water is further improved, and on the other hand, the mechanical damage to the floating algae is avoided.

[0066] Optionally, a plurality of water outlets are arranged on one side of the backwater pipe 710 for communicating with the cultivation pond 200, the plurality of water outlets are arranged in sequence along the width direction of the floating plant cultivation device, and the cultivation water in the cultivation pond 200 flows towards the length direction of the floating plant cultivation device. In this way, the plurality of water outlets are arranged in a waterfall type water outlet structure, so that the water outlet side of the backwater pipe 710 is subdivided into a plurality of branches; after the cultivation water pumped to the high end of the cultivation pond 200 by the circulating pump 720 is naturally subdivided, the water flow direction is stable and the water flow speed is slowed down, which is helpful for the floating algae to flow orderly to the low end of the backwater cavity 320.

[0067] Optionally, the collection net 500 is slidably arranged in the backwater cavity 320 along the height direction, so that the fixed position of the collection net 500 can be adjusted according to the amount of floating algae collected at one time, so that the collection net 500 is not blocked by too much floating algae, and the collection net 500 can be kept at a certain distance from the cultivation water in the backwater cavity 320 below, so that the water carried by the floating algae can be effectively drained.

[0068] Optionally, the collection net 500 is detachably arranged in the backwater cavity 320, so that after the collection net 500 collects enough floating algae, the collection net 500 can be detached and used as a carrier for transporting the floating algae.

[0069] The working process of the floating plant cultivation device is described as follows:

[0070] When duckweed grows normally until it is about to fill the whole cultivation pond 200, the gate 400 is opened and the circulating pump 720 starts to work. The circulating pump 720 pumps the cultivation water in the backwater chamber 320 to the high position area of the cultivation pond 200. With the water flow and gravity, the duckweed starts to drift to the low position end of the backwater pond 300. With the liquid level difference caused by the gate 400 gradually increasing, part of the duckweed falls to the collection net 500 with the water flow, and the other part of the duckweed is blocked by the retention plate 600 and is collected in the retention groove 610. The cultivation water forms a closed loop until the duckweed on other parts of the water surface basically all flows to the collection net, and then the circulating pump 720 is closed. In this way, the duckweed will be collected by the collection net 500, and the duckweed remaining in the cultivation pond 200 will be used for subsequent breeding.
