Description

Technical Field

[0001] The invention relates to the technical field of dew collection, and in particular to an automatic dew collection device for wild herb plants. Background Art

[0002] Dew is an important source of water for herbaceous plants, soil crusts, soil microorganisms and animals, especially in arid environments. It has unique isotopic characteristics and rich nutrient content, and therefore has important scientific research value. Organisms in arid environments rely on the presence of dew to maintain their life activities, and the isotopic characteristics of dew can provide important information about water cycles and environmental changes. In addition, the nutrient content in dew is also of great significance for studying the nutrient cycle of ecosystems.

[0003] However, due to the small amount of dew produced and its short existence, it is technically difficult to effectively collect it in the field. The existing manual collection methods are often inefficient, which limits the depth and breadth of dew research. Summary of the invention

[0004] In view of the above problems in the prior art, the present invention provides an automatic dew collection device for wild herbaceous plants, which solves the problem of low efficiency in manual dew collection.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] Provided is an automatic dew collecting device for wild herbaceous plants, comprising: an electric lifting member, on which a carrier which can be lifted and lowered in a vertical direction is arranged; a rotating motor, which is fixed on the carrier; an electric telescopic rod, which is used to rotate in a horizontal direction, and one end of which is fixedly connected to the rotating motor; and a dew collector, which comprises a shell fixed on the other end of the electric telescopic rod, the shell comprising a bottom plate, on the outer edge of which a plurality of comb teeth are fixed, a water conveying membrane is fixed between two adjacent comb teeth, a water collecting and guiding groove is arranged inside the bottom plate, a water inlet which is connected to the water collecting and guiding groove is arranged on the top surface of the bottom plate, a water outlet of the water collecting and guiding groove is arranged on the side of the bottom plate, and the water conveying membrane conveys dew on the herbaceous plants into the water collecting and guiding groove.

[0007] The working principle of this scheme is to determine the collection site of the dew on the herb, first determine the height suitable for collecting dew according to the height of the herb, then adjust the height of the dew collector through the electric lifting part, start the rotating motor, the rotating motor drives the dew collector to rotate in the horizontal direction, and the electric telescopic rod can gradually adjust the rotation radius. During the rotation of the dew collector, multiple comb teeth pass through the herb and drop the dew on it onto the water transfer membrane. The water transfer membrane sends the dew into the water collection and diversion trough for collection. After completing the dew collection in a circular area, the experimenter diverts the dew into the collection bottle through the outlet of the water collection and diversion trough.

[0008] Furthermore, a V-shaped opening is provided in the middle of each water transfer membrane, and the V-shaped opening faces the tip of the comb teeth. The V-shaped opening enables the end of the herb to enter the opening, and the two ends of the water transfer membrane opening are respectively located on both sides of the herb, so that when the water transfer membrane passes over and bends the end of the herb, both sides of the water transfer membrane can receive dew, thereby increasing the receiving area.

[0009] Furthermore, a hydrophilic coating or a bionic lotus leaf layer is provided on the surface of each water transport membrane. The hydrophilic coating may be a hydrophilic silicon oxide coating or a titanium oxide coating. The bionic lotus leaf layer is a bionic material based on the super-hydrophobic properties of the lotus leaf surface. This material imitates the micro-nano structure of the lotus leaf surface, so that the dew forms a high contact angle on its surface, thereby presenting a ball shape and having excellent water conductivity.

[0010] Furthermore, a plurality of dew inlets are provided on the outer end of the bottom plate, all of which are located below the water transfer membrane. Each dew inlet is connected to a flow channel, and the other end of the flow channel is inclined downward and connected to the water collection and diversion groove. Due to the characteristics of dew and the water transfer membrane, dew can slide along the lower surface of the water transfer membrane into the flow by relying on surface tension, thereby increasing the collection of dew.

[0011] Furthermore, the top projection of each dew inlet is funnel-shaped, each flow channel is in the shape of a Tesla valve structure, and the branch pipes of each flow channel are capillaries. When the rotating motor stops, the dew collected in the flow channel of the dew collector may spill out of the flow channel due to inertia, while the flow channel in the shape of a Tesla valve does not affect the flow rate during dew collection and has the characteristics of a one-way valve, which can prevent the gathered dew from spilling out of the flow channel. During the dew collection process, even if there is very little dew and it cannot fill the flow channel, a single dew drop in the shape of a water drop will move along multiple capillaries on the flow channel into the water collection and diversion groove under the action of capillary action and the relative movement of the dew collector.

[0012] Furthermore, a switch plate is slidably arranged on one side of the water collecting and guiding groove that is connected to the multiple flow channels. The switch plate is provided with connecting ports corresponding to the multiple flow channels one by one. The sliding switch plate closes or opens all the flow channels. Considering that the dew on the bottom plate may be contaminated by dust and impurities, the flow channel can be closed first by using the switch plate. Due to the arrangement of the Tesla structure, the flow channel will not spill the dew and can be used to buffer part of the dew. Therefore, when collecting dew, the dew flowing through the bottom plate can be collected first by the water collecting and guiding groove, and then the switch plate can be opened to collect the dew flowing out of the flow channel separately. This can reduce the risk of dew being contaminated and facilitate the comparison of experimental data of different dew.

[0013] Furthermore, a detachable end cap is provided at the connection port between each flow channel and the water collecting and guiding groove, and a cover plate for reducing dew evaporation is provided at the water inlet of the water collecting and guiding groove. The provision of the end cap facilitates the separate collection of dew in multiple flow channels, further increasing the comparative test data of dew.

[0014] Furthermore, a camera for detecting the height of the herb is provided on the electric telescopic rod near the dew collector, and the camera is electrically connected to the controller. The camera can obtain information about the herb through image recognition and feed it back to the controller, and the controller can control the height of the electric lifting member and the length of the electric telescopic rod through the visual information fed back by the camera. For example, when the height of one of the herb is too high, the controller can control the electric lifting member to raise the dew collector to avoid collision of the dew collector.

[0015] Furthermore, the electric lifting member is an electric push rod vertically fixed on the base, and the electric push rod and the electric telescopic rod are both electrically connected to the controller.

[0016] Furthermore, a super hydrophobic coating is provided on the top surface of the bottom plate, which facilitates dew to move along the top surface of the bottom plate.

[0017] The invention discloses an automatic dew collection device for wild herbaceous plants, which has the following beneficial effects:

[0018] 1. The present invention can automatically collect dew on herbs in a circular area, which speeds up the collection efficiency and saves time and effort compared to manual collection. The dew collector is driven to rotate in the horizontal direction by a rotating motor, and the rotation radius is gradually adjusted by an electric telescopic rod. During the rotation of the dew collector, multiple comb teeth pass through the herbs and drop the dew on them onto the water transport membrane. The water transport membrane sends the dew into the water collection and diversion trough for collection. After completing the dew collection in a circular area, the test personnel uniformly divert the dew into the collection bottle through the water outlet of the water collection and diversion trough.

[0019] 2. The present invention arranges multiple flow channels in the shape of Tesla valve structures, so that dew will not spill out from the flow channels when the dew collector slows down or stops, and the flow channels can be used alone as containers for buffering dew, which not only reduces the risk of dew pollution, but also facilitates the formation of multiple groups of comparative experimental data.

[0027] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0028] refer to Figure 1 This embodiment provides an automatic dew collection device for wild herbaceous plants, including an electric lifting member 1, a rotating motor 2, an electric telescopic rod 3 and a dew collector 4.

[0029] A platform 11 that can be lifted and lowered in the vertical direction is provided on the electric lifting member 1. The electric lifting member 1 in this embodiment is an electric push rod vertically fixed on a base, and the electric push rod and the electric telescopic rod 3 are both electrically connected to a controller.

[0030] The rotating motor 2 is fixed on the carrier 11 and is used to drive the dew collector 4 to rotate.

[0031] The electric telescopic rod 3 is used to rotate in the horizontal direction. One end of the electric telescopic rod 3 is fixedly connected to the rotating motor 2 , and the other end is used to fix the dew collector 4 .

[0032] refer to Figure 2 The dew collector 4 is used to collect dew, and includes a shell. The shell includes a bottom plate 43. A plurality of comb teeth 41 are fixed on the outer edge of the bottom plate 43. A water transfer membrane 42 is fixed between two adjacent comb teeth 41. A water collecting and diversion groove 44 is arranged inside the bottom plate 43. A water inlet connected to the water collecting and diversion groove 44 is opened on the top surface of the bottom plate 43. A cover plate for reducing dew evaporation is arranged at the water inlet of the water collecting and diversion groove 44. A water outlet of the water collecting and diversion groove 44 is opened on the side of the bottom plate 43. The water transfer membrane 42 transfers dew on the herbaceous plants to the water collecting and diversion groove 44.

[0033] In this embodiment, in order to facilitate the transport of dew, a hydrophilic coating or a bionic lotus leaf layer is provided on the surface of each water transport membrane 42, and a super hydrophobic coating is provided on the top surface of the bottom plate 43. The super hydrophobic coating is provided to facilitate the movement of dew along the top surface of the bottom plate 43. The hydrophilic coating in this embodiment can be a hydrophilic silicon oxide coating or a titanium oxide coating. The bionic lotus leaf layer is a bionic material based on the super hydrophobic properties of the lotus leaf surface. This material imitates the micro-nano structure of the lotus leaf surface, so that the dew forms a high contact angle on its surface, thereby presenting a ball shape and having excellent water conductivity.

[0034] In order to increase the area of ​​dew received by the water transfer membrane 42, a V-shaped opening is opened in the middle of each water transfer membrane 42, and the V-shaped opening faces the tip of the comb teeth 41. The V-shaped opening allows the end of the herb to enter the opening, and the two ends of the opening of the water transfer membrane 42 are respectively located on both sides of the herb, so that when the water transfer membrane 42 passes over and bends the end of the herb, both sides of the water transfer membrane 42 can receive dew, increasing the receiving area.

[0035] To increase the amount of dew collected, refer to Figure 2 and Figure 3 The outer end of the bottom plate 43 is provided with a plurality of dew inlets 431, all of which are located below the water transfer membrane 42. Each dew inlet 431 is connected to a flow channel 432. The other end of the flow channel 432 is tilted downward and connected to the water collection and diversion groove 44. Due to the characteristics of the dew and the water transfer membrane 42, the dew can slide along the lower surface of the water transfer membrane 42 into the flow by relying on surface tension, thereby increasing the collection of dew.

[0036] As a further structure of the flow channel 432, the top projection of each dew inlet 431 is funnel-shaped, each flow channel 432 is a Tesla valve structure, and the branch pipes of each flow channel 432 are capillaries. When the rotating motor 2 stops, the dew collected in the flow channel 432 in the dew collector 4 may spill out of the flow channel 432 due to inertia, while the flow channel 432 in the Tesla valve structure does not affect the flow rate during dew collection and has the characteristics of a one-way valve, which can prevent the gathered dew from spilling out of the flow channel 432. In the dew collection process, even if the dew is very little and cannot fill the flow channel 432, a single dew drop in the form of a water drop will move along the multiple capillaries on the flow channel 432 in sequence and enter the water collection and diversion groove 44 under the capillary action and the relative movement of the dew collector 4.

[0037] To reduce the risk of dew contamination, refer to Figure 3 to Figure 6 A switch plate 433 is slidably arranged on one side of the water collecting and guiding groove 44 that is connected to the multiple flow channels 432. The switch plate 433 is provided with communication ports corresponding to the multiple flow channels 432 one by one. The switch plate 433 is slid to close or open all the flow channels 432. Considering that the dew on the bottom plate 43 may be contaminated by dust and impurities, the flow channel 432 may be closed first by using the switch plate 433. The flow channel 432 may be used to buffer part of the dew because the Tesla structure does not spill the dew. Therefore, when collecting dew, the dew flowing through the bottom plate 43 may be collected first by the water collecting and guiding groove 44, and then the switch plate 433 may be opened to collect the dew flowing out of the flow channel 432 separately. This may reduce the risk of dew being contaminated and facilitate comparison of experimental data of different dew.

[0038] As another solution of this embodiment, in order to separately collect dew in each flow channel 432, a detachable end cap is provided at the connection port between each flow channel 432 and the water collecting and guiding groove 44. The provision of the end cap facilitates the separate collection of dew in multiple flow channels 432, further increasing the comparative test data of dew.

[0039] As a further solution of this embodiment, in order to avoid collision of the dew collector 4, a camera for detecting the height of the herb is provided on the electric telescopic rod 3 near the dew collector 4, and the camera is electrically connected to the controller. The camera can obtain information of the herb through image recognition and feed it back to the controller, and the controller can control the height of the electric lifting member 1 and the length of the electric telescopic rod 3 through the visual information fed back by the camera. For example, when the height of one of the herbaceous plants is too high, the controller can control the electric lifting member 1 to raise the dew collector 4 to avoid collision of the dew collector 4.

[0040] In order to facilitate remote observation by experimenters, the controller is electrically connected to the communication module, and the communication module transmits the information of the camera to the control terminal through the communication module. The experimenters can directly manually control the height of the electric lifting member 1 and the length of the electric telescopic rod 3, and can directly remotely control the collection of dew at a specific time point, thereby improving the operability of the automatic dew collection device for wild herbaceous plants.

[0041] In summary, the working principle of this solution is:

[0042] After determining the collection site of the herb dew, first determine the height suitable for collecting dew according to the height of the herb, then adjust the height of the dew collector 4 through the electric lifting part 1, start the rotating motor 2, the rotating motor 2 drives the dew collector 4 to rotate in the horizontal direction, and the electric telescopic rod 3 gradually adjusts the rotation radius. During the rotation of the dew collector 4, multiple comb teeth 41 pass through the herb and drop the dew on it onto the water delivery membrane 42. The water delivery membrane 42 delivers the dew on the upper and lower surfaces to the bottom plate 43 and the flow channel 432 respectively. The dew on the bottom plate 43 and the flow channel 432 flows into the water collection and diversion groove 44 for convergence. After completing the dew collection in a circular area, the experimenter diverts the dew into the collection bottle through the outlet of the water collection and diversion groove 44.

[0043] In order to prevent the dew on the bottom plate 43 from being contaminated by impurities, the experimenter can collect the dew on the bottom plate 43 and in the flow channel 432 separately.

[0044] Although the specific implementation of the invention is described in detail in conjunction with the drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
