Description

TECHNICAL FIELD

[0001] The utility model relates to the field of measurement technology, concretely to a novel height measuring pole. BACKGROUND

[0002] In the field of forest resource management, forestry investigation and ecological research, measuring the height of trees is a basic and important work. The traditional method of measuring the height of trees mainly relies on manual height measuring pole. This method has the following main drawbacks: first, it is laborious and time-consuming to manually extract the height measuring pole section by section, and the operation is complex, especially when measuring high trees, the labor intensity increases significantly; second, in the process of manual measurement, it is difficult to accurately control the alignment of the height measuring pole and the tree height, which may cause measurement error and affect the accuracy of the data; finally, the traditional height measuring pole is usually heavy, inconvenient to carry and install, and its maximum measurement height is limited, which is difficult to meet the measurement needs of higher trees.

[0003] The specification of Chinese utility model patent CN219473311U discloses a portable tree height measuring device, which comprises a supporting cylinder and a telescopic height measuring pole. The telescopic height measuring pole is achieved through a movable ring and a connecting rod. This design improves the accuracy of measurement through the alignment assembly, but still requires manual operation to extract the height measuring pole section by section, which is labor-intensive, and there are still problems of operation difficulty and measurement error when measuring high trees.

Therefore, there is an urgent need for a new type of height measuring pole that can realize multi-stage automatic lifting, accurate measurement and automatic locking function to overcome the shortcomings of the prior art and improve the measurement efficiency and accuracy.

Addressing the shortcomings of traditional methods for measuring tree height, it provides an efficient, accurate, and easy-to-operate height measurement solution, specifically including the following components and their interconnections:

[0043] The controller, as the core control unit of the height measuring pole, is responsible for receiving image signals from camera 5 and processing measurement data. The controller has a built-in display module for real-time display of measurement results, allowing users to intuitively observe the height of the trees.

A camera 5 is snapped onto the top of inner tube 3-4 for real-time observation and capture of images of tree height.

[0044] The outer ends of the inner tube one 2, the inner tube two 3 and the inner tube three 4 are fixedly connected with the rack 6, the rack 6 is provided with accurate scales, which is convenient for reading and measuring height, the camera 5 is installed at the top end of the inner tube three 4, communicates with the controller 1 through electrical connection, and transmits image data of the measured height in real time, the camera 5 has high definition and wide angle view, which ensures that the user can clearly observe the height position of the measured target, the rack 6 is fixedly connected to the outer ends of the outer tube 1, the inner tube one 2, the inner tube two 3 and the inner tube three 4, and the scales are arranged along the axial direction of the outer tube 1.

[0045] The rack 6 is clamped with the lifting slider 9, which ensures that the extension and retraction movement of the inner tube is synchronous with the movement of the rack, realizes accurate height adjustment, and the lifting mechanism 7 is fixedly connected to the position close to the top end of the outer end of the outer tube 1, which comprises the following components:

[0046] The sliding groove 7 is fixedly connected with the outer end of the outer tube 1, is symmetrically arranged, extends along the radial direction of the outer tube 1, provides a sliding path, the adjusting slider 8 is symmetrically arranged between the sliding grooves 7 and can slide along the radial direction of the outer tube 1 along the sliding grooves 7, adjusts the positioning of the lifting slider 9, the lifting slider 9 is symmetrically arranged between the adjusting sliders 8 and can slide along the axial direction of the outer tube 1 in the adjusting slider 8, the lifting slider 9 close to one end of the outer tube 1 is clamped with the rack 6, which drives the rack 6 to move away from the outer tube 1, the lifting slider 9 away from one end of the outer tube 1 adopts a wedge-shaped structure, which is convenient for being separated from the rack 6 when being pushed, prevents sliding from hindering, the connecting rod 10 is symmetrically arranged away from one end of the outer tube 1, is connected by rotating mode, drives the movement of the lifting slider 9, the gear one 11 is installed between the two connecting rods 10, the two connecting rods 10 are rotatably connected with the gear one 11, and the connection points are centrally symmetrically arranged with the center of gravity of the gear one 11, the gear two 12 is meshingly connected with the outer end of the gear one 11, is fixedly connected with the gear one 11 through the connecting block 13, ensures the stable meshing of the gear, the connecting block 13 is fixedly connected between the gear one 11 and the gear two 12, ensures the stable meshing and transmission of the gear, the motor 14 is installed on the gear two 12, is connected with the controller 1 through electrical connection, is responsible for driving the rotation of the gear two 12, thereby driving the movement of the gear one 11 and the connecting rod 10, realizes the automatic control of the lifting mechanism 7, the fixed support 15 is symmetrically arranged at the outer end of the outer tube 1, one end of the fixed support 15 is rotatably connected with the gear two 12, and the rotating shafts of the gear two 12 are both penetrated through the fixed support 15.

[0047] A handle 16 is fixedly connected to one end away from the motor 14, and a user can manually control the lifting mechanism 7 by rotating the handle 16. The handle 16 is fixedly connected to the fixed support 15, and a user can drive the rotation of the gear two 12 by manually rotating the handle 16 to achieve manual control of the lifting mechanism 7. As an auxiliary or backup mode of electric control, the spring 17 is installed in the sliding groove 7, one end of which abuts against the inner wall of the sliding groove 7, and the other end abuts against the adjusting sliding block 8. The spring 17 ensures that the lifting sliding block 9 is always in close contact with the corresponding rack 6 by continuously pushing the adjusting sliding block 8, thereby ensuring the stability and accuracy of the lifting process. The outer ends of the outer tube 1, the inner tube one 2, the inner tube two 3, and the inner tube three 4 are provided with precise scales for reading the measured height values. The scales are designed with easy-to-read markings to ensure that users can quickly and accurately obtain measurement results.

[0048] Working process

[0049] Preparation of the height measuring rod: Place the outer tube 1 vertically on the ground to ensure its stability. Make sure that the battery pack 15 is correctly installed and normally connected to the controller 1 and the motor 14 through electrical connection.

[0050] Start measurement: A user can choose to start the motor 14 through the controller 1 to achieve automatic lifting, or manually rotate the handle 16 to manually control the operation of the lifting mechanism 7. The start of the motor 14 drives the rotation of the gear two 12, which is transmitted through the gear one 11 to drive the synchronous movement of the two connecting rods 10.

[0051] Movement of the lifting sliding block: The movement of the connecting rod 10 drives the lifting sliding block 9 to slide along the axis direction of the outer tube 1. The lifting sliding block 9 near one end of the outer tube 1 is in mutual engagement with the rack 6, which pushes the rack 6 to move away from the outer tube 1. Due to the wedge-shaped structure design of the lifting sliding block 9 away from one end of the outer tube 1, it can smoothly separate from the rack 6 when pushed, avoiding hindering the sliding.

[0052] Extension of the inner tube: While the lifting sliding block 9 pushes the rack 6, the inner tube three 4, the camera 5, the inner tube two 3, and the inner tube one 2 are sequentially slid out along the axis direction of the outer tube 1 to achieve multi-stage lifting. This multi-stage lifting design overcomes the drawbacks of traditional height measuring rods that need to be manually extracted one by one, reduces the labor intensity of the operator, and improves the measurement efficiency. When the inner tube three 4 reaches the maximum extension length, the lifting sliding block 9 continues to push the inner tube two 3 and the rack 6 as well as the inner tube three 4 and the camera 5 to further extend, and finally pushes the inner tube one 2 to completely extend, ensuring that the measured height covers a larger range.

[0053] Height measurement: When inner tube one 2, inner tube two 3 and inner tube three 4 are fully extended and reach the desired height, the camera 5 observes the current height in real time, processes the image data through the controller 1, and the user reads the scale on the outer tube 1, inner tube one 2, inner tube two 3 and inner tube three 4 to obtain accurate measurement results. The position of the camera 5 ensures that the user can intuitively observe the alignment of the measuring rod and the tree height, reducing human measurement error and improving measurement accuracy.

[0054] Automatic fitting and elastic adjustment: During the movement of the lifting slider 9, the spring 17 in the sliding groove 7 continuously pushes the adjusting slider 8, so that the lifting slider 9 always fits the corresponding rack 6. This design ensures the stability and accuracy of the lifting process, avoids errors during sliding, and improves the reliability of the measurement.

[0055] Traditional measurement of tree height requires manual extraction of the measuring rod one by one, which is tedious and laborious, especially when measuring trees higher than 15 meters or 18 meters. This embodiment uses a multi-stage automatic lifting design, which significantly reduces the operation difficulty and labor intensity, and improves the work efficiency.

[0056] Traditional measurement methods cannot intuitively observe the alignment of the measuring rod and the tree height, which can easily lead to measurement errors. This embodiment installs a camera 5 at the top of the measuring rod, so that the user can observe the alignment of the measuring rod and the tree height in real time through the controller 1, ensuring the accuracy of the measurement and reducing human error.

[0057] Traditional measuring rods are usually limited to within 15 meters or 18 meters, and measuring beyond this height is inaccurate and difficult to operate. This embodiment uses a multi-stage telescopic design of inner tube one 2, inner tube two 3 and inner tube three 4, combined with stable control of the lifting mechanism 7, to achieve high-precision measurement beyond 18 meters, meeting higher measurement needs.

[0058] The new measuring rod uses a design of outer tube 1 and inner tube one 2, inner tube two 3, and inner tube three 4 connected in turn, which is compact in structure, easy to carry and install. Compared with traditional measuring rods, this design is more portable and convenient for users to use in the field.

[0059] The measuring rod can be automatically lifted by the motor 14 or manually controlled by the handle 16 to meet the operation needs in different scenarios. For example, when the power supply is insufficient or the motor fails, the user can still manually operate through the handle 16 to ensure the continuity and reliability of the measurement work.

[0060] The lifting mechanism 7 ensures the smooth movement of the lifting slider 9 through the precise meshing transmission of gear one 11 and gear two 12, and the symmetrical design of the connecting rod 10. The addition of spring 17 further ensures the close fit of the lifting slider 9 and the rack 6, avoiding sliding errors during lifting and improving the stability and reliability of the measurement. The components such as the lifting slider 9, the rack 6, the connecting rod 10, etc. are made of high-strength materials to ensure the durability and reliability of the height measuring rod during long-term use. At the same time, the modular design allows the components to be easily disassembled and replaced through the connecting block 13, facilitating daily maintenance and troubleshooting, extending the service life of the equipment. The built-in battery pack 15 provides stable power for the controller 1 and the motor 14, reducing dependence on external power sources and improving the portability and applicability of the equipment. At the same time, the electric lifting design reduces the energy consumption of human operation, in line with the design concept of energy saving and environmental protection.

[0061] Through the above design and implementation, the new height measuring rod described in embodiment 1 has significant advantages in structure, function and convenience of use, and can effectively overcome the shortcomings of traditional measuring rods such as complex operation, high labor intensity, high measurement error and limited measurement height, etc., meeting various height measurement needs and having wide application prospects.

[0062] Embodiment 2

[0063] As shown in Figures 1 to 11 , this embodiment further improves the structure and function of the new height measuring rod based on embodiment 1, especially adding the design of locking and unlocking devices and cover plates, enhancing the stability and convenience of use of the height measuring rod. The specific components and their connection methods include:

[0064] The motor 14 is installed at the outer end of the gear two 12 and fixedly connected with the fixed support 15, connected with the controller 1 through electrical connection, responsible for driving the rotation of the gear two 12, thereby driving the movement of the gear one 11 and the connecting rod 10, realizing the automatic control of the lifting mechanism 7.

[0065] The spring 17 in the sliding groove 7 is in contact with the inner wall of the sliding groove 7 at one end and with the adjusting slider 8 at the other end.

[0066] The spring 17 continuously pushes the adjusting slider 8 to ensure that the lifting slider 9 is always in close contact with the corresponding rack 6, ensuring the stability and accuracy of the lifting process.

[0067] The fixed support 15 is symmetrically arranged at the outer end of the outer tube 1, one end of the fixed support 15 is rotatably connected with the gear two 12, and the shaft of the gear two 12 penetrates through the fixed support 15 at both ends.

[0068] A handle 16 and a cover plate 20 are fixedly connected to one end away from the motor 14, and a user can manually control the lifting mechanism 7 by rotating the handle 16, and the cover plate 20 is used to protect the internal components and prevent dust and sundries from entering, thereby prolonging the service life of the device.

[0069] The handle 16 is fixedly connected to the fixed support 15, and a user can manually control the lifting mechanism 7 by rotating the handle 16 to drive the rotation of the gear two 12, thereby serving as an auxiliary or backup mode of the electric control.

[0070] The spring 17 is installed in the sliding groove 7, one end of which abuts against the inner wall of the sliding groove 7, and the other end abuts against the adjusting sliding block 8.

[0071] The spring 17 continuously pushes the adjusting sliding block 8, thereby ensuring that the lifting sliding block 9 is always in close contact with the corresponding rack 6, and ensuring the stability and accuracy of the lifting process.

[0072] The magnetic attraction device 18 is fixedly connected to a position near the top end of the outer tube 1, and a permanent magnet 21 is rotatably connected to the magnetic attraction device 18, thereby realizing the locking and unlocking functions of the inner tube.

[0073] The permanent magnet 21 changes the direction of the magnetic pole by rotating, and interacts with the permanent magnet in the locking device 19, thereby realizing automatic locking and unlocking.

[0074] The locking device 19 is fixedly connected to the bottom ends of the inner tube one 2, the inner tube two 3 and the inner tube three 4, thereby ensuring that the height measuring rod can be stably locked after reaching the predetermined height.

[0075] The locking device 19 is slidably connected with a permanent magnet 22, and the direction of the connecting line of the permanent magnet 22 is parallel to the radial direction of the outer tube 1.

[0076] The outer tube 1, the inner tube one 2 and the inner tube two 3 are all provided with a locking groove 23 near the top end, which cooperates with the outer end of the permanent magnet 22 on the locking device 19, and when the height measuring rod is extended to the upper limit, the permanent magnet 22 is attracted to the permanent magnet 21, the permanent magnet 22 is clamped into the locking groove 23, thereby realizing the locking of the inner tube one 2, the inner tube two 3 and the inner tube three 4.

[0077] The cover plate 20 is fixedly connected to one end of the fixed support 15 away from the outer tube 1, covers the outer end of the motor 14 and the gear two 12, thereby protecting the internal components from the external environment and prolonging the service life of the device.

[0078] Working process

[0079] Place the outer tube 1 vertically on the ground to ensure its stability.

[0080] Confirm that the battery pack 15 has been correctly installed and is normally connected with the controller 1 and the motor 14 through electrical connection.

[0081] Ensure that the magnetic device 18 and the locking device 19 are in the unlocked state, facilitate the subsequent telescopic operation.

[0082] Users can choose to start the motor 14 through the controller 1 to achieve automatic lifting; or manually rotate the handle 16 to achieve manual control of the lifting mechanism 7.

[0083] The start of the motor 14 drives the rotation of gear two 12, which is transmitted through gear one 11 to drive the synchronous movement of the two connecting rods 10.

[0084] The movement of the connecting rod 10 drives the lifting block 9 to slide along the axis of the outer tube 1.

[0085] The lifting block 9 near one end of the outer tube 1 is interlocked with the rack 6, which drives the rack 6 to move away from the outer tube 1.

[0086] Due to the wedge-shaped design of the lifting block 9 away from one end of the outer tube 1, it can smoothly separate from the rack 6 when pushed, avoiding hindering sliding.

[0087] While the lifting block 9 pushes the rack 6, the inner tube three 4, the camera 5, the inner tube two 3 and the inner tube one 2 are sequentially slid out along the axis of the outer tube 1, realizing multi-stage lifting.

[0088] This multi-stage lifting design overcomes the drawbacks of traditional height measuring rods that need to be manually extracted one by one, reducing the labor intensity of operators and improving measurement efficiency.

[0089] When the inner tube three 4 reaches the maximum extension length, the lifting block 9 continues to push the inner tube two 3 and the rack 6, as well as the inner tube three 4 and the camera 5 to further extend, and finally pushes the inner tube one 2 to fully extend, ensuring that the measurement height covers a larger range.

[0090] When the inner tube one 2, the inner tube two 3 and the inner tube three 4 are fully extended and reach the required height, the camera 5 observes the current height in real time and processes image data through the controller 1.

[0091] Users can obtain accurate measurement results by reading the scales on the outer tube 1, the inner tube one 2, the inner tube two 3 and the inner tube three 4.

[0092] The position of the camera 5 ensures that users can intuitively observe the alignment of the measuring rod and the tree height, reducing human measurement error and improving measurement accuracy.

[0093] During the movement of the lifting block 9, the spring 17 in the sliding groove 7 continuously pushes the adjusting block 8, so that the lifting block 9 always adheres to the corresponding rack 6.

[0094] This design ensures the stability and accuracy of the lifting process, avoids errors during sliding, and improves the reliability of measurement.

[0095] Locking of inner tubes:

[0096] When the inner tube one 2, the inner tube two 3 and the inner tube three 4 are extended from the outer tube 1 to the upper limit position, the permanent magnet 22 in the locking device 19 is attracted to the permanent magnet 21 on the magnetic attraction device 18.

[0097] The permanent magnet 22 is clamped into the locking slot 23, realizing stable locking of the inner tube one 2, the inner tube two 3 and the inner tube three 4, ensuring that the height measuring rod will not accidentally slide down when it is in the high position, increasing the safety and stability of use.

[0098] Unlocking and retracting of inner tubes:

[0099] When it is necessary to retract the inner tube one 2, the inner tube two 3 and the inner tube three 4, the user manually turns the permanent magnet 21 on the magnetic attraction device 18 to reverse its magnetic pole. The magnetic pole reversal pushes the permanent magnet 22 on the locking device 19 to retract, and the permanent magnet 22 is disengaged from the locking slot 23, realizing automatic unlocking. The user then manually presses the inner tube one 2, the inner tube two 3 and the inner tube three 4 to press the height measuring rod into the outer tube 1, completing the retracting operation.
