Abstract
Description
Technical Field
[0001] This utility model relates to the field of height measurement technology, specifically a shadow positioning height measurement device. Background Technology
[0002] In the field of modern measurement technology, height measurement has always been a crucial aspect of numerous engineering, scientific research, and everyday applications. Whether it's accurately measuring the height of buildings during construction, determining the elevation of terrain features in geographic surveying, or estimating the height of objects like trees and utility poles in daily life, efficient and accurate height measurement tools are indispensable.
[0003] Traditional height measurement methods are diverse, but all have certain limitations. For example, using a theodolite requires complex operating procedures and specialized personnel, and is greatly restricted by terrain conditions, making the measurement process cumbersome and inefficient. While laser rangefinders offer high measurement accuracy, they are expensive and may introduce measurement errors in certain special environments. Furthermore, some simple measuring tools, such as the pedometer method, are easy to operate, but their measurement accuracy is difficult to guarantee, and they can only be used over short distances, limiting their applicability.
[0004] Therefore, a shadow positioning height measurement device is needed to improve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a shadow positioning height measuring device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a shadow positioning height measuring device, including a standard pole, a hollow groove on the inner side of the standard pole, L-shaped mounting grooves on both sides inside the hollow groove, a winding drum placed inside the L-shaped mounting groove, and a handle fixedly provided at the upper end of the standard pole.
[0007] As a preferred embodiment of this utility model, the winding drum is provided with a winding shaft inside, and a graduated measuring tape is wound around the surface of the winding shaft. An insert plate is fixed at the other end of the graduated measuring tape.
[0008] As a preferred embodiment of this utility model, the standard upright is fixedly provided with a base at its bottom, and the surface of the base is provided with a slot, which is compatible with the insert plate.
[0009] As a preferred embodiment of this utility model, a sliding sleeve is fixedly provided on one side of the standard upright, and a sliding rod is slidably provided inside the sliding sleeve.
[0010] As a preferred embodiment of this utility model, a throttle is fixedly provided at one end of the slide rod, and a hexagonal head is fixedly provided at the other end of the slide rod.
[0011] As a preferred embodiment of this utility model, one end of the winding shaft is provided with a hexagonal mating groove, which is correspondingly provided with the hexagonal head and is adapted to the hexagonal head.
[0012] As a preferred embodiment of this utility model, the two ends of the winding shaft extend out of the two side surfaces of the winding drum, and the two ends of the winding shaft are slidably disposed inside the L-shaped mounting groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The height of the standard pole in this device is fixed. By observing the shaded scale of the standard pole, the proportional relationship can be accurately calculated. This fixed benchmark design ensures that the proportional calculation is accurate and reliable during the measurement process, thereby improving the accuracy of the height measurement of the object under test. The device has a stable base at the bottom, which can ensure that the standard pole is placed vertically and avoid measurement errors caused by the pole tilting. This stable support structure provides a solid foundation for measurement and further guarantees the accuracy of the measurement results.
[0015] 2. This device uses a retractable measuring tape for storage and unfolding via a winding drum and a retractable shaft. During measurement, the measuring tape can be easily unfolded along the side or shaded direction of the object being measured. After measurement, the measuring tape can be quickly rewound back into the drum using the handle and the hexagonal head with its hexagonal groove. This design makes the measurement process smoother and greatly improves measurement efficiency.
[0016] 3. This device can be used to measure objects of various heights, whether tall buildings, trees, or smaller objects, as long as they can cast a shadow. Its compact structure makes it easy to carry and use, making it particularly suitable for outdoor or complex environments. Attached Figure Description

[0029] Please see Figure 1-7This utility model provides a technical solution: a shadow positioning height measuring device, including a standard pole 2, a hollow groove 6 on the inner side of the standard pole 2, L-shaped mounting grooves 3 on both sides inside the hollow groove 6, a winding drum 7 placed inside the L-shaped mounting grooves 3, a handle 1 fixedly attached to the upper end of the standard pole 2, and a graduated measuring tape 11 unfolded along the side or shadow direction of the object to be measured. By observing the scale markings on the graduated measuring tape, since the height of the standard pole 2 is fixed, the shadow scale of the standard pole 2 is observed first to calculate the ratio, and then the height of the object to be measured is obtained by multiplying the shadow length of the object to be measured by the ratio.
[0030] As an example of this utility model, a winding shaft 8 is rotatably provided inside the winding drum 7, and a scale measuring tape 11 is wound around the surface of the winding shaft 8. An insert plate 10 is fixed at the other end of the scale measuring tape 11. The device is placed near the object to be measured, ensuring that the standard pole 2 is placed vertically and the base 4 stably supports the entire device. The insert plate 10 is inserted into the slot 5 on the surface of the base 4 to ensure that the end of the scale measuring tape 11 is fixed and to prevent it from shifting during the measurement process.
[0031] As an example of this utility model, a base 4 is fixedly provided at the bottom of the standard pole 2. A slot 5 is provided on the surface of the base 4. The slot 5 is adapted to the insert plate 10. A sliding sleeve 13 is fixedly provided on one side of the standard pole 2. A sliding rod 14 is slidably provided inside the sliding sleeve 13. A handle 12 is fixedly provided at one end of the sliding rod 14. A hexagonal head 15 is fixedly provided at the other end of the sliding rod 14. A hexagonal mating groove 9 is provided at one end of the winding shaft 8. The hexagonal mating groove 9 is correspondingly provided with the hexagonal head 15, and the hexagonal mating groove 9 is adapted to the hexagonal head 15.
[0032] As an example of this utility model, the two ends of the winding shaft 8 extend out of the two side surfaces of the winding drum 7, and the two ends of the winding shaft 8 are slidably set inside the L-shaped mounting groove 3. After the measurement is completed, the winding drum 7 is placed into the L-shaped mounting groove 3 through the winding shafts 8 at both ends. At this time, push the rotating handle 12 to make the hexagonal head 15 on the slide rod 14 cooperate with the hexagonal mating groove 9 at one end of the winding shaft 8. Continue to rotate the handle 12 to drive the winding shaft 8 to rotate, thereby rewinding the scale tape measure 11 back into the drum 7 and completing the device reset operation.
[0033] Working principle: When using, place the device near the object to be measured, ensure that the standard pole 2 is placed vertically and the base 4 stably supports the entire device, insert the insert plate 10 into the slot 5 on the surface of the base 4, and ensure that the end of the scale tape measure 11 is fixed to prevent it from shifting during the measurement process.
[0034] After the graduated measuring tape 11 is unfolded along the side or shadow direction of the object to be measured, the height of the object to be measured is obtained by observing the scale markings on the measuring tape. Since the height of the standard pole 2 is fixed, the shadow scale of the standard pole 2 is observed first to calculate the ratio. Then, the height of the object to be measured is obtained by multiplying the shadow length of the object to be measured by the ratio.
[0035] After the measurement is completed, the take-up drum 7 is placed into the L-shaped mounting groove 3 through the take-up shafts 8 at both ends. At this time, push the rotating handle 12 to make the hexagonal head 15 on the slide rod 14 engage with the hexagonal mating groove 9 at one end of the take-up shaft 8. Continue to rotate the handle 12 to drive the take-up shaft 8 to rotate, thereby rewinding the scale tape measure 11 back into the drum 7 and completing the device reset operation.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
