Description

Technical Field

[0001] This utility model relates to a locator, specifically a precise locator for field observation, belonging to the field of field plant research technology. Background Technology

[0002] Wild plants refer to plants that grow naturally in their native habitat. Wild plants are important natural resources and environmental elements, playing a vital role in maintaining ecological balance and economic development. Tracking and observing the growth of wild plants provides a comprehensive understanding of their habitat. Since wild plants often grow in areas with little human activity, these areas often contain a variety of other plants. Therefore, accurately locating and recording the location of plants during regular field observations is crucial for plant research and conservation.

[0003] However, traditional positioning methods often involve simple methods such as attaching marker tapes or boards to the stem diameter of the observed plant. However, due to the long observation period, these marker tapes or boards are prone to falling off, leading to significant errors. Furthermore, the large time span and significant plant changes make it easy for the markers to be lost, thus failing to meet the needs of precise observation. Additionally, in existing technologies, such as the grazing locator disclosed in CN108320446A, a ring-shaped sleeve is placed on the livestock, and a locator is installed on the sleeve. The locator transmits a positioning signal to the cloud to determine the livestock's exact location for easy retrieval. However, once located... If either alarm line on either side of the device is disconnected, the locator will emit an alarm signal. The cloud will receive the alarm signal and issue an alarm. Although the existing locators are designed for livestock, the satellite positioning method they use can also be applied to locating plants in the wild. The locator can be connected to the plant being observed to achieve accurate positioning. However, in actual use, the locator needs to be placed in the wild for a long time, which poses a significant risk of loss. If a tight binding method is used to fix the locator to the plant, it will affect the normal growth of the plant. Therefore, the existing locators are not well adapted to the positioning of plants observed in the wild. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 10 As shown, a precise field observation locator includes a locator body 1. A fixing and inserting component is connected to the lower part of the locator body 1. The fixing and inserting component is vertically inserted into the soil in the area where wild plants grow. An anti-theft rope 2 is also connected to the upper end of the fixing and inserting component. The rope body of the anti-theft rope 2 is wrapped around the root and stem of the wild plant. The fixing and inserting component provides stable support for the locator body 1. By vertically inserting the fixing and inserting component into the area where wild plants grow, the locator body 1 can be positioned on one side of the wild plant, thus enabling the location of the wild plant. Furthermore, the anti-theft rope 2 can connect the locator body 1 with the wild plant to be recorded and studied, thus forming a unique pairing between the locator body 1 and the wild plant to be recorded and studied. Even if there are wild plants of the same species in the surrounding area, the anti-theft rope 2 can accurately locate the wild plant to be recorded and studied. The anti-theft rope 2 also has a good anti-theft effect.

[0034] The locator body 1 includes a central processing unit 14, a satellite locator 15, and a buzzer 18. Both the satellite locator 15 and the buzzer 18 are connected to the central processing unit 14 via signal transmission. The central processing unit 14 is also connected to a peripheral handheld terminal device via signal transmission. The handheld terminal device can receive the positioning signal emitted by the satellite locator 15, allowing researchers to first locate the approximate area of ​​the locator body 1. Then, the handheld terminal device can send a further positioning signal to the central processing unit 14, causing the buzzer 18 to emit a beeping sound, thus enabling researchers to accurately locate the locator body 1. This allows for precise location and search of plants in the wild. It should be noted that the central processing unit 14 can be the same as the one disclosed in the geographic location positioning device with announcement number CN212623107U; the satellite locator 15 can use the Global Positioning System (GPS) or the BeiDou Navigation Satellite System to ensure that the measurement of plant location is accurate to the centimeter level.

[0035] The fixed installation assembly includes a locator support sleeve 3, a buried fixing sleeve 4, and a snap-fit ​​connecting rod 6. The locator support sleeve 3 is fixedly connected to the bottom of the locator body 1. The buried fixing sleeve 4 is inserted into the soil. One end of the snap-fit ​​connecting rod 6 is fitted with the locator support sleeve 3, and the other end of the snap-fit ​​connecting rod 6 is fitted with the buried fixing sleeve 4. The snap-fit ​​connecting rod 6 connects the locator support sleeve 3 and the buried fixing sleeve 4 together, thus achieving a firm connection between the locator body 1 and the fixed installation assembly. This facilitates researchers' location studies of discovered plants in the field, making the locator easy to assemble, carry, and operate, without adding excessive burden to fieldwork. Example 2

[0036] Improvements based on Example 1:

[0037] like Figure 1 , Figure 2 and Figure 3As shown, the locator body 1 also includes a locator housing 11 and a long-endurance battery 13. A partition 12 is horizontally fixedly connected inside the locator housing 11. The long-endurance battery 13, the central processing unit 14, and the satellite locator 15 are all fixedly installed on the partition 12, so that the locator housing 11 can be divided into upper and lower cavities by the partition 12. The cavity located above the partition 12 is a sealed cavity. Therefore, by fixing the long-endurance battery 13, the central processing unit 14, and the satellite locator 15 on the partition 12, the long-endurance battery 13, the central processing unit 14, and the satellite locator 15 can be located in the upper sealed cavity of the locator housing 11. This can prevent rainwater from seeping into the locator housing 11 and damaging the long-endurance battery 13, the central processing unit 14, or the satellite locator 15 when using the locator in the field. In addition, the long-endurance battery 13 can provide power for a longer period of time, ensuring that the positioning task can be completed within the observation period.

[0038] A buzzer fixing sleeve 16 is installed in the cavity below the partition plate 12 of the locator housing 11. The bottom end of the buzzer fixing sleeve 16 is fixedly connected to the bottom plate of the locator housing 11. Several sound guide holes 17 are opened through the bottom plate of the locator housing 11 located inside the buzzer fixing sleeve 16. A buzzer 18 is fixedly connected to the upper end of the buzzer fixing sleeve 16. The buzzer fixing sleeve 16 can make a certain gap between the buzzer 18 and the bottom plate of the locator housing 11, so as to prevent water from eroding the buzzer 18 when water seeps into the locator housing 11. Secondly, the sound emitted by the buzzer 18 is picked up by the buzzer fixing sleeve 16 and transmitted through the sound guide holes 17. However, the sound emitted by the buzzer 18 can be heard by the researchers to the maximum extent, so that the researchers can locate the position of the locator body 1 more quickly and accurately.

[0039] The sound guide hole 17 is flared, and a downward convex sidewall 19 is integrally connected to the edge of the bottom plate of the locator housing 11. Since the sound guide hole 17 is flared, that is, the bottom opening of the sound guide hole 17 is small, it can prevent rainwater from seeping in. Furthermore, the bottom edge of the downward convex sidewall 19 is lower than the bottom plate of the locator housing 11, which can further prevent rainwater from flowing along the outer surface of the locator housing 11 to the bottom plate of the locator housing 11.

[0040] like Figures 1 to 10As shown, an annular slot 31 is provided on the inner wall of the top end of the locator support sleeve 3. Two sets of contact pieces 32 are placed inside the annular slot 31. The two sets of contact pieces 32 are respectively connected to a connecting wire 33. The wire of the connecting wire 33 passes through the top end of the locator support sleeve 3, and the other end of the connecting wire 33 is placed inside the locator body 1 and connected to the signal receiving end of the central processing unit 14. The anti-theft rope 2 has an inner core wire 21 wrapped inside its rope body. The wire ends of the inner core wire 21 extending out of both ends of the anti-theft rope 2 are respectively locked in the annular slot 31, and the two wire ends of the inner core wire 21 are tightly attached to the contact piece 32, that is, the contact piece can pass through the contact piece. The function of wires 32 and 33 is to establish a circuit between the inner core wire 21 and the central processing unit 14. When the anti-theft rope 2 is damaged or broken, the inner core wire 21 and the central processing unit 14 are in an open circuit state. The central processing unit 14 can then receive a short circuit signal from the inner core wire 21, indicating that the anti-theft rope 2 is disconnected from the fixed installation component. There is a possibility that the locator may be deliberately damaged to steal the locator body 1 or wild plants. In other words, the anti-theft rope 2 can play a certain role in anti-theft warning. It should be noted that the signal transmission alarm principle between the inner core wire 21 of the anti-theft rope 2 and the central processing unit 14 can adopt the alarm line alarm principle disclosed in the grazing locator with announcement number CN 108320446A.

[0041] Furthermore, the inner wall of the locator support sleeve 3 is connected with several parallel, vertically distributed upper annular locking strips 35. One end of the locking and connecting rod 6 includes a support sleeve insertion rod 61. Several parallel, vertically distributed upper annular slots 63 are provided on the rod body of the support sleeve insertion rod 61. The upper annular locking strips 35 and the upper annular slots 63 are arranged one-to-one. When the support sleeve insertion rod 61 is inserted into the locator support sleeve 3, the upper annular locking strips 35 can be locked into the upper annular slots 63, thereby ensuring a more secure connection between the locator support sleeve 3 and the support sleeve insertion rod 61. It should be noted that the cross-sections of the upper annular locking strips 35 and the upper annular slots 63 are right-angled triangles, which can form a locking connection and prevent easy disassembly by humans later.

[0042] Furthermore, an annular insert 64 is integrally connected to the top of the support sleeve rod 61. The annular insert 64 is located directly below the annular slot 31. The top wall of the positioner support sleeve 3 is symmetrically provided with wire holes 34. The wire holes 34 are located on one side of the contact piece 32, which facilitates the insertion of the two ends of the inner core wire 21 into the positioner support sleeve 3. When the support sleeve rod 61 is inserted into the positioner support sleeve 3, the annular insert 64 can move upward until it is inserted into the annular slot 31, thereby pushing the two ends of the inner core wire 21 to a state of tight contact with the contact piece 32, so as to ensure that the connection between the ends of the inner core wire 21 and the contact piece 32 always maintains contact.

[0043] Furthermore, the other end of the buckle connecting rod 6 includes a fixing sleeve insertion rod 62. Several parallel, vertically distributed lower annular locking strips 65 are connected to the rod body of the fixing sleeve insertion rod 62. Several parallel, vertically distributed lower annular locking grooves 42 are opened on the inner wall of the buried fixing sleeve 4. The lower annular locking strips 65 and the lower annular locking grooves 42 are set one-to-one. When the fixing sleeve insertion rod 62 is inserted into the buried fixing sleeve 4, the upper annular locking strip 35 can be locked into the lower annular locking groove 42, thereby ensuring a more secure connection between the fixing sleeve insertion rod 62 and the buried fixing sleeve 4. It should be noted that the cross-section of the lower annular locking strip 65 and the lower annular locking groove 42 is a right-angled triangle, which can form a locking connection and prevent easy disassembly by humans later.

[0044] Furthermore, the bottom end of the buried fixing sleeve 4 is integrally connected with a buried cone 41. A rod through hole 43 is opened on the lower end of the pipe wall of the buried fixing sleeve 4. The rod through hole 43 is arranged in a cross shape with several layers. A reinforcing rod 5 is movably inserted into the rod through hole 43. The buried fixing sleeve 4 can be inserted into the soil layer more easily through the buried cone 41. After the buried fixing sleeve 4 is inserted and fixed, when the fixing sleeve rod 62 is vertically inserted into the buried fixing sleeve 4, the rod wall of the fixing sleeve rod 62 can push the reinforcing rod 5 outward. That is, multiple horizontal fixing points can be set on the outside of the pipe body of the buried fixing sleeve 4, which can further improve the positional stability of the buried fixing sleeve 4 after installation and make it difficult to pull out the buried fixing sleeve 4 easily, thus playing a certain role in preventing theft.

[0045] Furthermore, the reinforcing rod 5 is initially connected in pairs within the buried fixing sleeve 4, and the joints of adjacent reinforcing rods 5 are provided with joint points 51. The bottom end of the fixing sleeve insert rod 62 is integrally connected with a conical top block 66, which ensures that the reinforcing rod 5 can be installed relatively stably within the buried fixing sleeve 4 in the initial state. When the fixing sleeve insert rod 62 moves downward within the buried fixing sleeve 4, the conical top block 66 can abut against the center of the joint of the reinforcing rod 5. As the fixing sleeve insert rod 62 continues to move downward, the conical top block 66 can break the joint points 51 provided at the joint of the reinforcing rod 5, thereby pushing the reinforcing rod 5 outward.

[0046] Working principle: By vertically inserting the fixed mounting component into the growth area of ​​the wild plant, the locator body 1 can be positioned on one side of the wild plant. The anti-theft binding rope 2 is wrapped around the root and stem of the wild plant. The anti-theft binding rope 2 connects the locator body 1 with the wild plant to be recorded and studied, thus forming a unique pairing between the locator body 1 and the wild plant to be recorded and studied. Even if there are wild plants of the same species in the vicinity, the anti-theft binding rope 2 can accurately locate the wild plant to be recorded and studied. The anti-theft binding rope 2 also has a good anti-theft effect. When positioning is required, the positioning signal emitted by the satellite locator 15 is received through the external handheld terminal device. This allows researchers to first find the approximate area of ​​the location of the locator body 1, and then send a further positioning signal to the central processing unit 14 through the handheld terminal device, causing the buzzer 18 to emit a buzzing indication sound. This allows researchers to accurately locate the location of the locator body 1, thereby achieving precise positioning and locating of wild plants.
