Technical Field

[0001] The present invention relates to the technical field of land area measurement, and particularly to an area measurement device for national territorial space planning. Background Art

[0002] When carrying out national territorial space planning, the measurement of land area is a crucial step. Traditional land measurement methods usually rely on manual use of tools such as tape measures and rangefinders for measurement, and there are the following problems: 1. Low measurement accuracy: Manual measurement is easily affected by factors such as terrain and environment, resulting in large measurement errors; 2. Complicated operation: Traditional measurement tools require multiple people to cooperate. Especially when measuring large areas of land, the operation is cumbersome and time-consuming; 3. Inconvenient marking: During the measurement process, it is usually necessary to mark on the ground. The traditional method of marking is not precise enough, and the spraying of marking materials (such as lime) is uneven.

[0003] 4. Unintelligent data recording: Traditional measurement tools cannot automatically record measurement data and rely on manual recording, which is prone to errors and has low efficiency.

[0004] With the development of intelligent technology, automated and intelligent measurement tools have gradually been introduced in the field of land measurement. However, existing intelligent measurement devices are often costly and have complicated operations, making it difficult to be widely used in grass-roots national territorial space planning. Summary of the Invention

On both sides of the docking column, side disks are fixedly installed, and the docking column and the two side disks form a double-disk frame structure. On each side disk, two groups of symmetrically distributed moving components are installed, and through the moving components, the double-disk frame structure moves parallel to the ground; A rotatable rotating cylinder is sleeved on the docking column, and a measuring tape for measuring the length of the land is wound on the rotating cylinder. Protective disks are fixedly sleeved on both ends of the rotating cylinder; On the inner disk wall of any one of the side disks, a Hall sensor is fixedly installed, and on the outer wall of the protective disk corresponding to the Hall sensor, a magnet is fixedly installed. Through the Hall sensor and the magnet, a ranging system for measuring the length of the land is formed.

[0009] Preferably, one end of the tension spring is fixedly connected to the inner top wall of the installation groove, and the other end of the tension spring is fixedly connected to the upper surface of the sliding seat.

[0010] Preferably, the guide roller is located below the side disk, and the guide roller abuts against the outermost layer of the measuring tape wound around the rotating cylinder.

[0011] Preferably, a marker is further installed on the side disk. The marker includes a funnel for storing lime. The funnel is fixedly installed on the outer disk wall of the side disk through a frame, and a curved ash discharging pipe is fixedly installed at the material discharging port of the funnel.

[0012] Preferably, an electromagnetic valve is fixedly installed at the material discharging port of the funnel.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 10 , an area measuring device for territorial space planning provided by an embodiment of the present invention, the area measuring device for territorial space planning includes a docking column 1, a rotating cylinder 2, a measuring tape 3 and a distance measuring system.

[0021] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 , both sides of the docking column 1 are fixedly installed with side plates 11, and the docking column 1 and the two side plates 11 form a double-plate frame structure. A rotating cylinder 2 is sleeved on the docking column 1 in a rotatable connection manner, and a measuring tape 3 for measuring the length of the land is wound on the rotating cylinder 2. Protective plates 21 are fixedly sleeved on both ends of the rotating cylinder 2. The inner wall of any one of the side plates 11 is fixedly installed with a Hall sensor 4, and a magnet 5 is fixedly installed on the outer wall of the protective plate 21 corresponding to the Hall sensor 4. A distance measuring system for measuring the length of the land is formed by the Hall sensor 4 and the magnet 5; Two groups of symmetrically distributed moving components 8 are installed on each side plate 11. Through the moving components 8, the double-plate frame structure can be moved parallel to the ground, so as to facilitate the staff to push the double-plate frame structure to move on the land to be measured.

[0022] It should be noted that when measuring the area of the soil body, the staff locates and measures the end of the measuring tape 3 at the starting point (either by using a ground nail or by pressing it by hand), and then pushes the double-disk frame structure to move it along the boundary of the measured land. Therefore, when the measuring tape 3 is stretched, the length of the measured land can be measured. At the same time, since the measuring tape 3 is pulled out of the rotating cylinder 2, the rotating cylinder 2 can rotate around the docking column 1. Therefore, the Hall sensor 4 can continuously detect the magnetic field change of the magnet 5 to generate pulses and record the number of rotations of the protection disk 21. In each scheme, the circumference of the protection disk 21 is designed to be one meter. Therefore, the number of rotations of the protection disk 21 is the measured length, and its error does not exceed 1 meter. At the same time, the ranging system and the measuring tape 3 form a double-measurement structure, which greatly improves the accuracy of length measurement in form. After measuring the lengths of each side of the measured land, its area can be calculated.

[0023] It should be noted that a positioning ring is fixedly installed at the end of the measuring tape 3 for the staff to use a ground nail or hold it for positioning.

[0024] In the embodiment of the present invention, please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 8 , a pressing tape component 6 for pressing against the measuring tape 3 is installed on the double-disk frame structure, and the pressing tape component 6 includes a guiding roller 61. U-shaped frames 62 are rotatably installed on both sides of the guiding roller 61, and a connecting member 63 is installed on each U-shaped frame 62. The two connecting members 63 are respectively installed in the installation grooves 11a opened on the two side disks 11. The connecting member 63 includes a sliding rod 631, the sliding rod 631 is fixedly installed in the installation groove 11a, and a sliding seat 632 is slidably sleeved on the sliding rod 631 and a tension spring 633 is sleeved, and the connecting end of the sliding seat 632 is fixedly connected to the U-shaped frame 62.

[0025] It should be noted that in the initial state, the guiding roller 61 abuts against the outermost layer of the measuring tape 3 under the action of the tension spring 633, avoiding the hidden danger of the measuring tape 3 being scattered when not in use; When using the measuring tape 3 for measurement, since the guiding roller 61 abuts against the outermost layer of the measuring tape 3, after the measuring tape 3 is pulled out of the rotating cylinder 2, the guiding roller 61 can drive the measuring tape 3 to be in a straightened state, avoiding the hidden danger of inaccurate measurement caused by the bending of the measuring tape 3 during measurement. And when the wound measuring tape 3 is continuously stretched, the guiding roller 61 continuously abuts against the outermost layer of the measuring tape 3 under the action of the tension spring 633, avoiding the loosening of the measuring tape 3 wound on the rotating cylinder 2; Among them, since the guiding roller 61 is rotatably arranged, when the measuring tape 3 is pulled outwards, the guiding roller 61 is driven to rotate, so that the measuring tape 3 slides out more smoothly.

[0026] Furthermore, one end of the tension spring 633 is fixedly connected to the inner top wall of the mounting groove 11a, and the other end of the tension spring 633 is fixedly connected to the upper surface of the sliding seat 632, thereby avoiding the phenomenon that the tension spring 633 in the compressed state bounces up and down along the sliding rod 631 after the pressure is instantly released.

[0027] In this solution, the guide roller 61 is located below the side plate 11, and the guide roller 61 abuts against the outermost measuring tape 3 wound around the rotating cylinder 2, so as to facilitate the rotation of the measuring tape 3 along the guide roller 61 after being pulled out from the bottom of the double-disk frame structure, and the guide roller 61 abuts against the next layer of the measuring tape 3 under the action of the elastic force of the tension spring 633.

[0028] In an embodiment of the present invention, please refer to Figure 2 and Figure 9 , a marker 7 is further installed on the side plate 11, and the marker 7 includes a funnel 71 for storing lime. The funnel 71 is fixedly installed on the outer wall of the side plate 11 through a frame, and a curved ash discharge pipe 72 is fixedly installed at the material discharge port of the funnel 71, and a solenoid valve is fixedly installed at the material discharge port of the funnel 71.

[0029] It should be noted that when measuring the length of the soil body, the solenoid valve is opened so that the lime stored in the funnel 71 is sprinkled onto the measured land from the curved ash discharge pipe 72, thereby forming an effective mark. Therefore, the staff can mark it while measuring, without manual operation, simplifying the process after measurement.

[0030] In an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , the moving component 8 includes a bracket 81. The bracket 81 is rotatably installed on the outer wall of the side plate 11, and a rotatably connected roller 82 is sleeved on the installation end of the bracket 81. The moving component 8 further includes a pneumatic damping rod 83. One end of the pneumatic damping rod 83 is fixedly installed on the side plate 11, and the other end of the pneumatic damping rod 83 is fixedly installed on the bracket 81. A spring 84 is sleeved on the pneumatic damping rod 83, and both ends of the spring 84 are fixedly connected to the side plate 11 and the bracket 81 respectively.

[0031] It should be noted that the roller 82 provided on the side plate 11 facilitates the movement of the double-disk frame structure along the land. Since a spring 84 is sleeved on the pneumatic damping rod 83 installed between the bracket 81 and the side plate 11, the spring 84 and the pneumatic damping rod 83 constitute a shock-absorbing structure, thereby reducing the stability of the double-disk frame structure when traveling along the ground.

[0032] In an embodiment of the present invention, please refer to Figure 1 Figure 2 and Figure 10, on the outer disk wall of any one of the side disks 11, a side connection post 111 is fixedly installed, and a pushing member 9 is installed on the side connection post 111. The pushing member 9 includes a handle 91. An insertion rod 92 with a sliding connection is inserted into the through hole opened in the handle 91. The other end of the insertion rod 92 is sleeved on the side connection post 111 and is rotatably connected to the side connection post 111. A threaded through hole is opened on the rod wall of the handle 91 close to the insertion rod 92, and a fastening screw rod 93 with a threaded connection is inserted into the threaded through hole.

[0033] It should be noted that: Since the handle 91 and the internally provided insertion rod 92 form a telescopic structure, it is convenient for the staff to adjust the length of the handle 91 to cope with different terrains.

[0034] This application integrates multiple functions such as measurement, marking, and movement, and can meet various requirements for land area measurement in territorial space planning. Through an integrated design, the problem of carrying multiple devices by traditional measurement tools is reduced, and the efficiency and practicality of measurement are improved.

[0035] In addition, this solution can also be optimized into an intelligent device. Specifically, a wireless transmission module (such as Bluetooth or Wi-Fi) is integrated to transmit measurement data to a smartphone, tablet, or cloud server in real time. Through a supporting application, users can view measurement data in real time and automatically generate a measurement report, reducing errors in manual recording; the double-disk frame structure can be built with a Beidou module (or GPS module), combined with Beidou technology (or GIS technology), to achieve precise positioning of measurement data and geographical information annotation. Through Beidou module positioning, the device can automatically record the longitude and latitude coordinates of the measurement area and combine the measurement data with the geographical information system to generate an accurate land area distribution map. The double-disk frame structure can be equipped with a voice prompt system to guide the staff to operate through voice. For example, when the measurement is completed, the system can inform the measurement result through voice prompt, or issue a warning when an operation error occurs, improving the convenience and safety of operation.

[0036] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
