Description

Technical Field

[0001] This utility model relates to the field of sampling device technology, specifically a mangrove insect sampling device. Background Technology

[0002] Mangrove insects refer to the insect groups that live in the mangrove ecosystem. Mangroves are wetland ecosystems that grow in the intertidal zone of tropical and subtropical coasts and are composed of mangrove plants and other organisms. They have unique ecological environments, such as the confluence of fresh and salt water, high and low tides, rich bottom mud, and biodiversity. Mangrove insects have adapted to this special environment and have some unique adaptive characteristics.

[0003] Mangrove insect sampling devices are specialized tools or equipment used to collect and monitor insects in mangrove ecosystems. Due to the special nature of mangrove environments, which are often intertidal, muddy, or saline-alkali, these devices typically need to be adapted to humid and corrosive environments and designed to accommodate the habitat characteristics of insects.

[0004] However, existing mangrove insect sampling devices often fail to collect insects efficiently due to the complex terrain of mangrove areas and the wide and active distribution of insects. This results in the insects being easily captured flying away and being damaged during the sampling process, which affects subsequent research. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mangrove insect sampling device, which solves the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mangrove insect sampling device, comprising a square mounting base, a square groove formed at the center of the inner side of the square mounting base, a transmission screw rotatably mounted at the center of the inner side of the square groove, a square nut seat threadedly mounted on the outer side wall of the transmission screw, an outer protective shell fixedly mounted on the upper end of the square nut seat, irregularly shaped mounting blocks symmetrically fixedly mounted on the upper end of the outer protective shell, a threaded screw rotatably mounted at the center of the inner side of the outer protective shell, an irregularly shaped nut seat threadedly mounted on the outer side wall of the threaded screw, support rods symmetrically mounted on both sides of the irregularly shaped nut seat, and an irregularly shaped sampling cover rotatably opened and closed above the symmetrical support rods.

[0010] Preferably, each of the two symmetrical irregular-shaped sampling covers has a sealing locking block fixedly installed at the center of one side, and each of the two symmetrical irregular-shaped sampling covers has a flexible brush installed at the center of the inner side.

[0011] Preferably, irregularly shaped mounting plates are symmetrically installed at each of the four corners of the lower end of the square mounting base, and a rotary motor is fixedly installed at the center of one end of the square mounting base, with a transmission screw installed at the output end of the rotary motor.

[0012] Compared with the prior art, this utility model provides a mangrove insect sampling device, which has the following beneficial effects:

[0013] 1. By setting up threaded screws and transmission screws, as well as two symmetrical irregularly shaped sampling covers, it is possible to move the irregularly shaped sampling covers to different positions and open and close them quickly and stably to efficiently collect mangrove insects.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments. Example

[0024] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a mangrove insect sampling device, including a square mounting base 1, a square groove 2 formed at the center of the inner side of the square mounting base 1, a transmission screw 3 rotatably mounted at the center of the inner side of the square groove 2, a square nut seat 4 rotatably mounted on the outer side of the transmission screw 3, and a bearing embedded in the square groove 2 to reduce the friction loss of the transmission screw 3 and ensure that the square nut seat 4 rises and falls smoothly. An outer protective shell 5 is fixedly mounted on the upper end of the square nut seat 4, and irregularly shaped mounting blocks 6 are symmetrically fixedly mounted on the upper end of the outer protective shell 5. A threaded screw 7 is rotatably mounted at the center of the inner side of the outer protective shell 5, and an irregularly shaped nut seat 8 is rotatably mounted on the outer side of the threaded screw 7.

[0025] On both sides of the irregular nut seat 8, two support rods 9 are symmetrically and rotatably installed. The irregular nut seat 8 has an H-shaped structure, with the support rods 9 hinged to the ears on both sides, which converts the rotational motion of the threaded screw 7 into the fan-shaped unfolding of the support rods 9. An irregular sampling cover 13 is rotatably and openably installed above the two symmetrical support rods 9. The square mounting base 1 is made of high-strength corrosion-resistant alloy material and the surface is treated with a special coating to resist the erosion of the high-salt and humid environment of mangroves and extend the service life of the device. The inner wall of the square groove 2 is precision polished, and the fit with the transmission screw 3 reaches the micron level, ensuring the stability and accuracy of the transmission screw 3 when rotating.

[0026] The transmission screw 3 and the square groove 2 are rotatably connected by a bearing, and the threaded screw 7 and the outer protective shell 5 are also rotatably connected by a bearing. The bearing can reduce friction during transmission, improve the transmission efficiency and service life of the device. The bearing adopts a sealed deep groove ball bearing, which can effectively prevent mud and water in the mangrove forest from entering the bearing, avoiding bearing wear and corrosion. At the same time, the bearing balls and raceway surfaces are specially hardened to improve the bearing's load-bearing capacity and wear resistance.

[0027] Two symmetrical irregularly shaped mounting blocks 6 are each symmetrically and rotatably mounted with opening and closing rods 10 at their lower ends, and two symmetrically and rotatably mounted with transmission rods 11 at their upper ends. The shape of the irregularly shaped mounting blocks 6 is optimized by fluid dynamics, which can effectively reduce air resistance during device movement. At the same time, it is equipped with a reinforcing rib structure inside to enhance the strength and rigidity of the mounting blocks and ensure the stability of the opening and closing rods 10 and transmission rods 11 when rotating. The two symmetrical opening and closing rods 10 are hinged to the other end of the support rod 9 at their middle. A fixing block 12 is fixedly installed at the center of one side of the two symmetrical irregularly shaped sampling covers 13. The hinged installation part uses a self-lubricating bearing, which does not require additional lubricant, reduces maintenance costs, and reduces the friction coefficient at the hinge, making the linkage between the opening and closing rods 10 and the support rod 9 smoother.

[0028] The surface of the fixing block 12 is provided with anti-slip texture to enhance the firmness of the connection with the opening and closing rod 10 and the transmission rod 11. The upper end of the two symmetrical opening and closing rods 10 and the other end of the two symmetrical transmission rods 11 are respectively fixedly installed at the center of the two symmetrical fixing blocks 12. The inner center of the outer protective shell 5 is fixedly installed with a drive motor. The output end of the drive motor is equipped with a threaded screw 7. The drive motor is a high-precision servo motor with high torque and low noise. It can accurately control the rotation angle and speed of the threaded screw 7, thereby realizing the precise opening and closing of the irregular sampling cover 13. The drive motor and the threaded screw 7 are connected by a high-precision coupling to ensure the stability and accuracy of power transmission.

[0029] At the lower four corners of the square mounting base 1, irregularly shaped mounting plates 16 are symmetrically installed in pairs. Due to the complex environmental conditions of mangrove forests, some are mudflats or flooded areas that are difficult to reach on foot. For flooded areas, boats are used for access. The irregularly shaped mounting plates 16 have bearings that allow them to rotate, making it easy and quick to install them on boats or mudflat vehicles to sample insects in the mangrove forests. A rotary motor 17 is fixedly installed at the center of one end of the square mounting base 1. A transmission screw 3 is installed at the output end of the rotary motor 17. The rotary motor 17 drives the transmission screw 3 to rotate, thereby driving the square nut seat 4 and the outer protective shell 5 to move longitudinally, expanding the sampling range of the irregularly shaped sampling cover 13 for insects in the mangrove forests. The rotary motor 17 is a high-torque stepper motor that can provide sufficient power to drive the transmission screw 3 and has a self-locking function. It can automatically lock after the device is raised or lowered to the designated position to ensure the stability of the device. Example

[0030] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a sealing locking block 14 that is interlocked and locked is fixedly installed at the center of one side of each pair of symmetrical irregular-shaped sampling covers 13, and the sealing locking block 14 has a "dovetail groove" structure in cross section. When closed, it produces an interference fit to prevent small aquatic insects from leaking out. Flexible bristles 15 are installed at the center of the inner side of each pair of symmetrical irregular-shaped sampling covers 13, and the flexible bristles 15 are coated with insect aggregation hormone to improve the trapping efficiency. The sealing locking block 14 achieves a tight seal between the irregular-shaped sampling covers 13 to prevent insects from escaping during the sampling process. The flexible bristles 15 can gently sweep the insects into the sampling cover during sampling to avoid damaging the insects. The sealing locking block 14 is made of elastic silicone material, which has good flexibility and sealing performance.

[0031] When the irregularly shaped sampling cover 13 is closed, it forms a tight seal. The flexible bristles 15 are made of soft and wear-resistant nylon. The length and density of the bristles are scientifically designed to effectively clean insects without damaging their wings, antennae, or other vulnerable parts. The irregularly shaped sampling cover 13 is made of a transparent and lightweight material, which facilitates observation of the insects inside the cover and reduces the overall weight of the device, making it easy to move and operate in the mangrove environment. The irregularly shaped sampling cover 13 is made of polycarbonate, which has high strength, high transparency, and impact resistance. It can withstand certain external impacts and protect the insect samples inside. Its density is only half that of traditional glass, effectively reducing the weight of the device.

[0032] The remaining structure is the same as that in Example 1.

[0033] The workflow of this utility model is as follows:

[0034] First, the mangrove insect sampling device is based on a square mounting base 1. A square groove 2 is opened at the center of the inner side of the square mounting base 1. A transmission screw 3 is rotatably installed in the square groove 2. The transmission screw 3 is threadedly connected to a square nut seat 4. The irregularly shaped mounting plates 16 at the four corners of the lower end of the square mounting base 1 can be flexibly installed on a boat or a mudflat vehicle. A rotary motor 17 at the center of one end drives the transmission screw 3 to rotate, causing the square nut seat 4 and the outer protective shell 5 above to move longitudinally, expanding the sampling range. Irregularly shaped mounting blocks 6 are symmetrically fixed at the upper end of the outer protective shell 5. A threaded screw 7 is rotatably installed at the center of the inner side. The threaded screw 7 is driven by a drive motor inside the outer protective shell 5, and its outer side wall is threadedly connected to an irregularly shaped nut seat 8.

[0035] Two symmetrical support rods 9 are mounted on each side of the irregular nut seat 8. An irregular sampling cover 13 is mounted on the top of the support rods 9. An opening and closing rod 10 and a transmission rod 11 are mounted on the upper and lower ends of the irregular mounting block 6, respectively. The opening and closing rod 10 is hinged to the support rod 9 in the middle. The upper ends of the opening and closing rod 10 and the transmission rod 11 are fixed to the fixing block 12 at the center of one side of the irregular sampling cover 13, forming a linkage structure.

[0036] Secondly, when sampling is required, the rotary motor 17 starts, driving the transmission screw 3 to rotate, so that the outer protective shell 5 reaches the appropriate position. Then, the drive motor works, driving the threaded screw 7 to rotate. The irregular nut seat 8 moves along the threaded screw 7. Through the linkage of the support rod 9, the opening and closing rod 10 and the transmission rod 11, the irregular sampling cover 13 opens and closes. During the opening and closing process, the two symmetrical irregular sampling covers 13 can move to different positions to collect insects. Moreover, a sealing block 14 with interlocking interlocking is installed on the center of one side of the irregular sampling cover 13. When closed, it seals tightly to prevent insects from escaping. The flexible bristles 15 installed in the center of the inner side can gently sweep insects into the sampling cover to avoid damaging the insects.

[0037] Finally, after sampling is completed, the drive motor reverses, and the irregularly shaped sampling cover 13 closes, trapping the insect inside. The height of the device can then be adjusted by rotating the motor 17 to facilitate the removal of samples or the transfer of the device to other sampling locations. Through the coordinated operation of its components, the entire device achieves efficient and non-destructive sampling of insects in the complex environment of mangroves.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
