Description

Technical Field

[0001] The utility model relates to the technical field of algae collection, in particular to a device for collecting algae grown on an artificial substrate. Background Art

[0002] The species diversity of attached algae is an important aquatic organism in the assessment of the ecological health of rivers and lakes. Sampling and testing of attached algae is of great significance for objectively and accurately evaluating the ecological health of river water, understanding the impact and effect of various ecological environments on river ecosystems, and strengthening river ecological protection and ecological restoration.

[0003] When using biological organisms to monitor water ecological conditions, the sampling site is often limited by the lack of suitable natural matrices, and samples collected from natural matrices can only be used for qualitative determination, not quantitative determination. Therefore, artificial matrices are currently used for sampling, which have the advantages of being able to be placed at will, having a uniform surface, and being able to control the type, area, and direction of the surface.

[0004] However, when the existing sampling device is arranged in water, it is easily affected by the fluctuation of the water surface and the airflow above the water surface, resulting in poor stability on the water surface and failure to keep the sampling device at a fixed depth in the water relative to the water surface.

[0005] How to develop an artificial substrate-attached algae collection device to improve stability and wind resistance on the water surface and enable the sampling device to maintain a fixed depth in the water from the water surface has become a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] The utility model discloses an artificial substrate algae collection device, comprising a buoyancy unit and a sampling unit, wherein a connecting rod is fixedly mounted on the lower surface of the buoyancy unit, the sampling unit is sleeved on the connecting rod, and the sampling unit abuts against the connecting rod;

[0009] It also includes a counterweight positioning unit, which is fixedly connected to the connecting rod;

[0010] The sampling unit comprises a fixed frame and a glass slide, a fixed groove is installed on the opposite surface of the inner side wall of the fixed frame, and the glass slide is installed in the fixed groove;

[0011] The fixing frame is in contact with the side wall of the connecting rod via fixing bolts.

[0012] Preferably, the buoyancy unit includes a buoyancy frame, and the outer side wall of the buoyancy frame is threadedly connected to one end of the telescopic rod; the other end of the telescopic rod is fixedly installed with a floating ball.

[0013] Preferably, the shape of the buoyancy frame is circular.

[0014] Preferably, scale lines are provided on the outer side wall of the connecting rod away from the set bolt.

[0015] Preferably, the weight positioning unit includes a hanging ring and a traction line. The hanging ring is fixedly connected to the bottom of the connecting rod. One end of the traction line is fixedly connected to the hanging ring, and the other end of the traction line is fixedly connected to a weight.

[0016] Preferably, a water baffle is further included. The water baffle abuts against the outer side wall of the fixed frame, and the water baffle abuts against the set bolt through an elastic washer.

[0017] Compared with the prior art, the beneficial technical effects of the present utility model are as follows:

[0018] For an artificial substrate epiphytic algae collection device of the present utility model, by adjusting the length of the telescopic rod on the buoyancy frame, the stability performance of the buoyancy frame on the water surface can be greatly improved, ensuring that the buoyancy frame will not capsize due to the influence of water flow and / or air flow on the water surface. Further, by adjusting the moving length of the fixed frame on the connecting rod, it can be ensured that the glass slide on the fixed frame always maintains a fixed distance from the water surface, is not affected by the rise and fall of the water surface, and has a small shielding effect on the glass slide on the fixed frame, enabling the glass slide to receive appropriate light.

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] As Figures 1-3 shown, an artificial substrate epiphytic algae collection device includes a buoyancy unit and a sampling unit. A connecting rod 4 is fixedly installed on the lower surface of the buoyancy unit. The sampling unit is sleeved on the connecting rod 4, and the sampling unit abuts against the connecting rod 4;

[0026] It further includes a weight positioning unit, and the weight positioning unit is fixedly connected to the connecting rod 4;

[0027] The sampling unit includes a fixed frame 5 and a glass slide 6. Fixed grooves are installed on the opposite inner side walls of the fixed frame 5, and the glass slide 6 is installed in the fixed grooves. Further, rubber blocks are installed in the fixed grooves to enhance the firmness when the glass slide is installed in the fixed grooves and prevent the glass slide from falling out of the fixed frame under the influence of water flow;

[0028] The fixed frame 5 abuts against the side wall of the connecting rod 4 through a set screw 7, so that the fixed frame and the buoyancy unit form an integral body, enabling the fixed frame to move as the buoyancy unit floats, so that the glass slide on the fixed frame will not be affected by the rise and fall of the water surface and always remains at a fixed depth under the water surface, which can effectively ensure that the light intensity received by the epiphytic algae remains consistent.

[0029] Specifically, the buoyancy unit includes a buoyancy frame 1, and the outer side wall of the buoyancy frame 1 is threadedly connected to one end of a telescopic rod 2; the other end of the telescopic rod 2 is fixedly installed with a floating ball 3, and the anti-tipping performance and wind resistance of the buoyancy frame are improved by adjusting the length of the telescopic rod.

[0030] Specifically, the shape of the buoyancy frame 1 is circular, which can further improve the stability of the buoyancy frame on the water surface, prevent the buoyancy frame from tipping over under the influence of water flow, air flow and / or the pulling action of the weight assembly, and can block the sunlight on the fixed frame to the lowest extent.

[0031] Specifically, scale lines are provided on the outer side wall of the connecting rod 4 away from the set screw 7, which is convenient for sampling personnel to adjust the distance between the fixed frame and the buoyancy frame. The numerical range of the scale lines is 0-30 cm, and the adjustment range is relatively large, which can meet the collection of epiphytic algae at different water depths;

[0032] During the actual sampling process, the relative distance between the fixed frame and the buoyancy frame is adjusted to 5-15 cm, which can enable the artificial substrate to receive appropriate light.

[0033] Specifically, the counterweight positioning unit includes a lifting ring 8 and a towing line 9. The lifting ring 8 is fixedly connected to the bottom of the connecting rod 4. One end of the towing line 9 is fixedly connected to the lifting ring 8, and the other end of the towing line 9 is fixedly connected to a counterweight 10. The lifting ring is directly connected to the connecting rod and not to the fixed frame, so that the pulling force will not be transmitted to the fixed frame. During the sampling process, the depth of the fixed frame in the water can be unaffected and remain consistent all the time;

[0034] When the counterweight sinks into the water, it can pull the buoyancy assembly through the connecting rod, and limit the buoyancy assembly within a preset water surface range by controlling the length of the towing line, preventing the buoyancy assembly from deviating from the sampling area and affecting the accuracy of sampling.

[0035] Specifically, it further includes a water baffle 11. The water baffle 11 abuts against the outer wall of the fixed frame 5, and the water baffle 11 abuts against the set screw 7 through an elastic washer. The water baffle is made of a flexible transparent plastic plate, which can greatly improve the environmental adaptability during the arrangement of the fixed frame, so that the glass slide on the fixed frame can cope with the rapids and swirls in the water during sampling.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or sequence between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0037] The embodiments described above are only descriptions of the preferred modes of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
