Description

Technical Field

[0001] This utility model relates to the technical field of collection devices, and in particular to a biological detection and collection device for intertidal sediments. Background Technology

[0002] In fields such as marine ecological environment research, environmental monitoring, and biological resource surveys, the biological detection of intertidal sediments is of vital importance. As a transitional zone between the ocean and the land, the intertidal zone contains rich biological information in its sediments. This information can reflect key aspects such as the ecological environment status, biological community structure, and degree of environmental pollution in the area. Accurate and efficient collection of intertidal sediment samples is the foundation for subsequent biological detection and analysis.

[0003] Currently, the sampling devices used for intertidal sediment biological detection on the market have a relatively simple structure. They usually consist of a sleeve, a sampling tube, and a rotating handle that controls the vertical movement of the sampling tube within the sleeve. In actual use, the operator rotates the handle to insert the sampling tube into the intertidal ground, thereby completing the sampling operation.

[0004] However, most existing sampling tubes are single-tube designs. During the sampling process, in order to reduce random errors and ensure the reliability of the test data, according to the testing specifications, each sampling point needs to be sampled repeatedly, generally 3-5 times. This means that operators need to perform multiple sampling operations at a single sampling point. Moreover, before the next sampling, the sampling tube must be cleaned to prevent the previous sample from contaminating the subsequent sample. This series of operations is not only cumbersome and greatly increases the workload of operators, but also significantly reduces the overall work efficiency, making the entire sampling process time-consuming and labor-intensive, and difficult to meet the needs of large-scale, high-efficiency intertidal sediment biological testing. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose an intertidal sediment biological detection and collection device. This utility model has a reasonable structure. Through the structure of the sleeve, sampling tube and cylindrical shell, a dual-axis motor is used in conjunction with the first and second unidirectional transmissions to realize the synchronous lifting and lowering of the sampling tube for sampling and discharge, and the drainage hole tube drives the cleaning brush to rotate for cleaning. The design of multiple sampling tubes reduces repetitive operations, the transparent material and scale lines facilitate observation, and the battery is suitable for field use, which improves the sampling efficiency and reliability.

[0007] To achieve the above objectives, this utility model proposes an intertidal sediment biological detection and collection device, comprising:

[0008] Sleeve: An inner cylinder seat is provided at the top center. The inner wall of the inner cylinder seat is arranged vertically with a first one-way drive, a dual-shaft motor and a second one-way drive, and the three are connected in a driving connection. An outer cylinder seat is evenly arranged on the outer side of the inner cylinder seat. The bottom of the sleeve is open. A reciprocating screw is rotatably connected to the top wall of the sleeve. The reciprocating screw is connected in a driving connection with the second one-way drive, and a lower frame is threaded on its outer surface. The lower frame slides in a vertical fit with the inner wall of the sleeve.

[0009] Sampling tube: It is uniformly threaded and connected to the inner wall of the lower frame, and its position corresponds one-to-one with that of the outer cylinder seat;

[0010] Cylindrical housing: threadedly connected to the top of the inner cylinder seat, with a water collection groove on the top. An internal gear is rotatably connected to the inner wall of the cylindrical housing and is connected to the first one-way transmission device. An external gear is uniformly meshed with the outer side of the internal gear. The external gear is rotatably connected to the inner wall of the cylindrical housing. A drain hole pipe is fixedly connected to the center of the surface of the external gear. One end of the drain hole pipe passes through the inside of the water collection groove and is sealed and connected to it. The other end passes through the outer cylinder seat and passes through the corresponding sampling tube. A cleaning brush and a piston are arranged sequentially along its length.

[0011] In addition, the intertidal sediment biodetector proposed in the above application may also have the following additional technical features:

[0012] Specifically, a handle is provided on the outer wall of the sleeve, and guide grooves and guide blocks are respectively provided on the inner wall of the sleeve and the lower frame surface at corresponding positions. The guide blocks are slidably connected to the inner wall of the guide groove in the vertical direction.

[0013] Specifically, both the sleeve and the sampling tube are made of transparent material, and the sampling tube has scale lines on its surface; the first one-way drive and the second one-way drive have opposite one-way drive directions, and both are ratchet-type one-way drives.

[0014] Specifically, the inner wall of the water collection tank is uniformly and fixedly connected with sealed bearings, and the installation position of the sealed bearings is collinear with the axis of the drain hole pipe; one end of the drain hole pipe that penetrates into the water collection tank is inserted into the inner ring of the sealed bearing and forms an interference fit with the inner wall of the inner ring to achieve synchronous rotation and sealing of the two.

[0015] Specifically, an ultrasonic generator is embedded inside the piston, and a circuit channel is opened inside the drain hole pipe.

[0016] Specifically, the cylindrical housing has a controller on its surface, a battery inside, and an internal gear and an external gear separated by a partition; the battery, controller, dual-axis motor and ultrasonic generator are connected by wires to form a closed electrical circuit.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Efficiently complete multiple sampling: The multi-sampling tube design can complete 3-5 repeated samplings required for a collection point in a single operation, eliminating the need for multiple sampling operations, greatly reducing operation steps and significantly improving work efficiency.

[0020] 2. Ensure sampling consistency and accuracy: A dual-axis motor drives a reciprocating screw to synchronously raise and lower multiple sampling tubes, ensuring that the insertion depth of each sampling tube is consistent, avoiding depth deviations caused by manual operation, and improving sample reliability; at the same time, compared with traditional rotary handle operation, motor drive is more labor-saving and reduces labor intensity.

[0021] 3. Convenient sampling tube cleaning: The integrated drain pipe and cleaning brush, combined with the lifting action of the sampling tube, can efficiently clean the inner wall of the sampling tube. The water collection tank supplies water and the cleaning brush rotates, eliminating the need for manual disassembly and cleaning. The operation is simple and time-saving, and avoids sample contamination.

[0022] 4. Observe and control the sample status: The cannula and sampling tube are made of transparent material, and the sampling tube has scale lines on its surface, which allows for direct observation of the sample volume and sampling status, and facilitates real-time control of the sampling process.

[0023] 5. Achieve single-power dual-function drive: The first and second unidirectional transmissions adopt a ratchet design in opposite directions. The dual-axis motor drives the sampling tube lifting (sampling / discharging) and the cleaning component rotating (cleaning) in forward and reverse directions respectively. No additional power source is required, and the structure is compact and easy to operate.

[0024] 6. Improved cleaning effect and component fit: The piston is embedded with an ultrasonic generator, which can clean dirt on the piston surface and ensure a tight seal between the piston and the inner wall of the sampling tube; the sealed bearing design ensures the sealing of the drain tube when it rotates, preventing water leakage from affecting cleaning or sampling.

[0025] 7. Suitable for field operation scenarios: Equipped with a rechargeable battery, it eliminates the need for an external power source, meeting the needs of use in intertidal field environments; the controller can precisely control the sampling depth and operation process, improving operational accuracy.

[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0034] The following description, in conjunction with the accompanying drawings, describes an embodiment of an intertidal sediment biological detection and collection device of the present invention.

[0035] like Figures 1-4 As shown, an intertidal sediment biodetector according to an embodiment of the present invention includes:

[0036] Sleeve 1: An inner cylinder seat 11 is provided at the top center. The inner wall of the inner cylinder seat 11 is arranged vertically with a first one-way drive 12, a dual-shaft motor 13 and a second one-way drive 14, and the three are connected in a transmission. An outer cylinder seat 15 is evenly arranged on the outer side of the inner cylinder seat 11. The bottom of the sleeve 1 is open. A reciprocating screw 16 is rotatably connected to the top wall of its inner side. The reciprocating screw 16 is connected in a transmission with the second one-way drive 14, and a lower frame 17 is threaded on its outer surface. The lower frame 17 slides with the inner wall of the sleeve 1 in a vertical direction.

[0037] Sampling tube 2: It is uniformly threaded and connected to the inner wall of the lower frame 17, and corresponds one-to-one with the position of the outer cylinder seat 15;

[0038] Cylindrical housing 3: threaded connection to the top of inner cylinder seat 11, with a water collection groove 31 on the top. An internal gear 32 is rotatably connected to the inner wall of the cylindrical housing 3 and is connected to the first one-way transmission device 12. An external gear 33 is uniformly meshed on the outer side of the internal gear 32. The external gear 33 is rotatably connected to the inner wall of the cylindrical housing 3. A drain hole pipe 34 is fixedly connected to the center of the surface of the external gear 33. One end of the drain hole pipe 34 passes through the inside of the water collection groove 31 and is sealed and connected to it. The other end passes through the outer cylinder seat 15 and passes through the corresponding sampling tube 2. A cleaning brush 35 and a piston 36 are arranged sequentially along its length.

[0039] It should be noted that the piston 36 described in this embodiment is provided in two sets, which are respectively provided on the top side and the bottom side of the cleaning brush 35.

[0040] It should be noted that both the cleaning brush 35 and the piston 36 described in this embodiment are detachable structures.

[0041] Specifically, this utility model has a reasonable structure. Through the structure of the sleeve 1, sampling tube 2 and cylindrical shell 3, the dual-axis motor 13, together with the first one-way transmission 12 and the second one-way transmission 14, realizes the synchronous lifting and lowering of the sampling tube 2 for sampling and discharge, and the drainage hole pipe 34 drives the cleaning brush 35 to rotate and clean. The design of multiple sampling tubes 2 reduces repetitive operations, the transparent material and scale lines make it easy to observe, and the battery 38 is suitable for field use, which improves the sampling efficiency and reliability.

[0042] Before use: Sampling tube 2 is located inside the upper part of sleeve 1, cleaning brush 35 is inside sampling tube 2, and two sets of pistons 36 block the top and bottom openings of sampling tube 2 respectively to ensure that there are no impurities in the tube before sampling.

[0043] Sampling process: The device is placed in the sampling area. The dual-axis motor 13 is started to rotate forward via the controller 37. The power of the dual-axis motor 13 is transmitted to the reciprocating screw 16 through the second one-way transmission 14, causing it to rotate. This drives the threaded lower frame 17 to descend vertically along the inner wall of the sleeve 1 (the guide groove 19 and the guide block 110 cooperate to ensure the stability of the descent). This drives multiple sets of sampling tubes 2 to be inserted into the ground simultaneously to complete the sediment sampling. When the lower frame 17 moves to the end of the reciprocating screw 16 (reaching the set sampling depth), the reciprocating screw 16 continues to rotate with the dual-axis motor 13, driving the lower frame 17 and the sampling tubes 2 to rise along the screw until they return to the inside of the sleeve 1, at which point the dual-axis motor 13 stops.

[0044] Sampling process: The lifting device is raised and a collection box is placed below. The dual-axis motor 13 is started again, and the sampling tube 2 continues to rise. When the sample comes into contact with the piston 36 below, the sample in the tube is discharged into the collection box through the relative movement of the piston 36 and the sampling tube 2.

[0045] Cleaning process: When the sampling tube 2 needs to be cleaned, the dual-axis motor 13 is started and reversed. The power is transmitted to the internal gear 32 through the first one-way transmission 12. The internal gear 32 drives the meshing external gear 33 to rotate, which in turn causes the drain hole pipe 34 connected to the external gear 33 to rotate. The water in the water collection tank 31 flows into the sampling tube 2 through the drain hole pipe 34. At the same time, the rotating cleaning brush 35 contacts the inner wall of the sampling tube 2. With the adjustment of the lifting position of the sampling tube 2, the inner wall is thoroughly cleaned. The ultrasonic generator embedded in the piston 36 can simultaneously clean the dirt on the surface of the piston 36 to ensure that there is no residual contamination in the next sampling.

[0046] In one embodiment of this utility model, such as Figure 3 As shown, a handle 18 is provided on the outer wall of the sleeve 1, and a guide groove 19 and a guide block 110 are respectively provided on the inner wall of the sleeve 1 and the surface of the lower frame 17. The guide block 110 is slidably connected to the inner wall of the guide groove 19 in the vertical direction.

[0047] Specifically, the handle 18 is designed for easy carrying, and the guide groove 19 and guide block 110 are designed to improve the operational stability of the lower shelf 17.

[0048] In one embodiment of this utility model, such as Figure 3 As shown, both the sleeve 1 and the sampling tube 2 are made of transparent material, and the surface of the sampling tube 2 is provided with scale lines; the one-way transmission directions of the first one-way actuator 12 and the second one-way actuator 14 are opposite, and both are ratchet-type one-way actuators.

[0049] Specifically, the sleeve 1 and the sampling tube 2 are made of transparent material, and the surface of the sampling tube 2 is provided with scale lines, which allows for intuitive observation of the sample volume and sampling status, and facilitates real-time control of the sampling process; the first one-way drive 12 and the second one-way drive 14 adopt a ratchet design in opposite directions, and drive the sampling tube 2 to lift (sampling / discharging) and the cleaning component to rotate (cleaning) by the forward and reverse rotation of the dual-axis motor 13, respectively, without the need for an additional power source, and the structure is compact and easy to operate.

[0050] In one embodiment of this utility model, such as Figure 4 As shown, sealed bearings 311 are uniformly fixedly connected to the inner wall of the water collection tank 31, and the installation position of the sealed bearings 311 is collinear with the axis of the drain hole pipe 34; one end of the drain hole pipe 34 that penetrates into the water collection tank 31 is inserted into the inner ring of the sealed bearing 311 and forms an interference fit with the inner wall of the inner ring to achieve synchronous rotation and sealing of the two.

[0051] Specifically, the sealed bearing 311 is designed to ensure the sealing of the drain pipe 34 when it rotates, preventing water leakage from affecting cleaning or sampling.

[0052] In one embodiment of this utility model, such as Figure 4 As shown, an ultrasonic generator is embedded inside the piston 36, and a circuit channel is opened inside the drain hole pipe 34.

[0053] It should be noted that the ultrasonic generator described in this embodiment is not shown in the diagram.

[0054] Specifically, the ultrasonic generator is designed to facilitate the cleaning of dirt on the surface of piston 36, allowing it to better fit with the inner wall of sampling tube 2.

[0055] In one embodiment of this utility model, such as Figure 4 As shown, a controller 37 is provided on the surface of the cylindrical housing 3, and a storage battery 38 is provided inside it. The internal gear 32 and the external gear 33 are separated by a partition 39. The storage battery 38, the controller 37, the dual-axis motor 13 and the ultrasonic generator are connected by wires to form a closed electrical circuit.

[0056] Specifically, it is equipped with a rechargeable battery 38, eliminating the need for an external power source and meeting the needs of use in the intertidal zone field environment; the controller 37 can precisely control the sampling depth and operation process, improving operational accuracy.

[0057] In summary, the intertidal sediment biological detection and collection device of this utility model has a reasonable structure. Through the structure of the sleeve 1, sampling tube 2 and cylindrical shell 3, the dual-axis motor 13, together with the first one-way drive 12 and the second one-way drive 14, realizes the synchronous lifting and lowering of the sampling tube 2 for sampling and discharge, and the drainage hole pipe 34 drives the cleaning brush 35 to rotate and clean. The design of multiple sampling tubes 2 reduces repetitive operations, the transparent material and scale lines facilitate observation, and the battery 38 is suitable for field use, which improves the sampling efficiency and reliability.
