Description

Technical Field

[0001] This invention belongs to the field of land surveying and mapping, specifically a land surveying and mapping device used in the land use management stage. Background Technology

[0002] Land surveying refers to the process of understanding topography and land area through measurement and mapping. It is a necessary operation for land management. The existing land surveying equipment consists of two parts: a tripod and a total station. When setting up the land surveying equipment, the tripod is responsible for the coarse leveling of the equipment. That is, the tripod needs to adjust the length and angle of the three support rods to keep the total station mounting platform at the top of the tripod roughly horizontal. After placing the total station on the mounting platform, the total station is operated to perform fine leveling before the surveying equipment can be set up.

[0003] On flat and solid ground, a tripod can achieve coarse leveling with small adjustments. After coarse leveling, the tripod can remain stable for a long time without external force. However, when setting up a tripod on soft or uneven ground, it is not only necessary to make large adjustments to the length difference of the three support rods, but also easy to cause horizontal deviation due to the sinking of one or more support rods during the surveying process, requiring re-leveling. In view of the above inconvenience, this invention proposes a land surveying device for use in the land use management stage. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the prior art by providing a land surveying device used in the land use management stage.

[0005] The present invention achieves the above objectives through the following technical solutions: A land surveying device for use in the land use management stage includes a total station, a combined support for adjusting the height of the total station, and a base for providing a horizontal support surface for the combined support. The base includes a support plate, several sliding rods that penetrate the support plate, and an inflatable component sleeved on the outside of the rods. The rods are used to fix the base to the ground and limit the highest point of the support plate's range of motion. The inflatable component is used to push the support plate upward along the rods to the highest point by inflating and deforming after the rods are inserted into the ground. The inflatable component can fit against the ground after being inflated.

[0006] As a further optimization of the present invention, the inflation assembly includes a wind cover sleeved on the outside of the insert rod, with airbags connected above and below the wind cover. A sealing sleeve is embedded in the side wall of the airbag and can slide along the insert rod. The insert rod has a hollow structure and is connected to the wind cover through a slot in the side wall. An air inlet seat is connected to the top of the insert rod. A one-way valve for connecting an external inflation device is provided on the support plate, and the air inlet seat is connected to the one-way valve through a hose.

[0007] As a further optimization of the present invention, the insert rod is provided with a sliding slide rod, and a number of side rods arranged in a circular array are provided between the bottom end of the slide rod and the bottom plate of the insert rod. The side rods are made of elastic metal material, and the side wall of the insert rod is provided with a through groove that cooperates with the side rods.

[0008] As a further optimization of the present invention, the combined bracket includes a mounting base for mounting a total station. A center plate is provided below the mounting base and the center plate is connected to the mounting base through a lifting mechanism. Several support rods are provided below the center plate. The lifting mechanism includes a rotatable gear ring embedded in the center of the center plate and several screws provided below the mounting base. Several screw sleeves corresponding to the screws are embedded in the center plate and are rotatable. Gears that mesh with the gear ring are sleeved on the outer side of the screw sleeves.

[0009] As a further optimization of the present invention, the support rods are arranged in a ring array, the top of the support rods are rotatably connected to the middle plate and the bottom of the support rods are rotatably connected to a locking block, and the base is provided with a number of locking seats that correspond one-to-one with the locking blocks.

[0010] As a further optimization of the present invention, a sealing plug is provided on the air intake seat. The sealing plug has a conical structure and is elastically connected to the air intake seat by a spring.

[0011] The beneficial effects of this invention are as follows: 1. This land surveying device for land use management uses a pole, a support plate, and an inflation mechanism to restrict the support plate to a horizontal angle. The inflation mechanism provides support between the ground and the support plate, ensuring the support plate remains horizontal on uneven ground. This provides a horizontal support surface for the combined support frame, allowing the total station to be fixed on the combined support frame and thus completing the coarse leveling process. The device is easy and efficient to operate, eliminating the need for repeated adjustments. Furthermore, the inflation component, once inflated, wraps around the pole and conforms to the ground, increasing the support area and preventing the pole from sinking due to soft ground. This comprehensively solves the problems mentioned in the background technology.

[0012] 2. In this device, the coarse leveling function of the total station is achieved through the base and the inflation mechanism, while the height adjustment function is achieved through the lifting mechanism. These two functions are independent of each other. After coarse leveling is completed, i.e., after the support plate is fixed in a horizontal position, the height of the total station can be adjusted arbitrarily within the adjustable range of the lifting mechanism. During this process, the horizontal state of the support plate remains unaffected, eliminating the need for multiple coarse leveling adjustments during device setup. The entire assembly, consisting of the mounting base, center plate, lifting mechanism, and support rods, can be disassembled and folded from the base. Disassembly and folding significantly reduces the overall size of the device, facilitating transport. Attached Figure Description

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1

[0017] like Figure 1-6 As shown, the land surveying device for the land use management stage in this embodiment includes a total station 8, a combined support for adjusting the height of the total station 8, and a base 1 for providing a horizontal support surface for the combined support. The base 1 includes a support plate 101, several sliding rods 102 that penetrate the support plate 101, and an inflatable assembly 4 sleeved on the outside of the rods 102. The rods 102 are used to fix the base 1 on the ground and limit the highest point of the range of motion of the support plate 101. The inflatable assembly 4 is used to push the support plate 101 upward along the rods 102 to the highest point by inflating and deforming after the rods 102 are inserted into the ground. The inflatable assembly 4 can fit against the ground after being inflated.

[0018] When setting up this land surveying device, firstly, all the poles 102 are vertically inserted into the ground, ensuring the tops of all poles 102 are flush. Then, an external inflation device is used to inflate the inflation assembly 4. During inflation, the volume of the inflation assembly 4 continuously deforms and increases as it fills with gas. On one hand, the deformation of the inflation assembly 4 pushes the support plate 101 upwards, causing it to slide along the poles 102 to its highest point. On the other hand, as the volume of the inflation assembly 4 gradually increases, its outer wall gradually conforms to the ground, thus expanding the contact area between each support point of the base 1 and the ground, preventing damage to the poles 102. After the inflatable component 4 is inflated, it presses upwards to press against the support plate 101 and downwards to press against the ground. Even if the ground is uneven, causing different distances between the various points on the horizontal support plate 101 and the ground, the inflatable component 4 can adapt by adjusting the degree of inflation, thus providing support between the support plate 101 and the uneven ground. After the base 1 is installed, the combined bracket is placed on the base 1 as a whole. After the total station 8 is fixed on the mounting base 3, the total station 8 is in a state of coarse leveling. Then, the height of the total station 8 is adjusted by adjusting the combined bracket and the total station 8 is finely leveled to complete the erection of this surveying device.

[0019] The inflation assembly 4 includes a wind cover 401 sleeved on the outside of the insert rod 102. Airbags 402 are connected to the top and bottom of the wind cover 401. A sealing sleeve 403 is embedded in the side wall of the airbag 402. The sealing sleeve 403 can slide along the insert rod 102. The insert rod 102 has a hollow structure and is connected to the wind cover 401 through a slot in the side wall. An air inlet seat 5 is connected to the top of the insert rod 102. A one-way valve for connecting an external inflation device is provided on the support plate 101, and the air inlet seat 5 is connected to the one-way valve through a hose. After connecting an external inflation device, the gas passes through the one-way valve, hose, air inlet seat 5 and insert rod 102 into the wind cover 401, and finally passes through the wind cover 401 into the two airbags 402. The two airbags 402 expand and extend vertically to both ends under the filling of gas. One airbag 402 will press the support plate 101 upward and the other will press the ground downward.

[0020] The combined support includes a mounting base 3 for mounting a total station 8. A center plate 2 is located below the mounting base 3, and the center plate 2 is connected to the mounting base 3 via a lifting mechanism 7. Several support rods 6 are located below the center plate 2. The lifting mechanism 7 includes a rotatable gear ring 701 embedded in the center of the center plate 2 and several screws 704 located below the mounting base 3. Several threaded sleeves 703, corresponding one-to-one with the screws 704, are embedded inside the center plate 2 and are rotatable. The outer side of each threaded sleeve 703 is fitted with a sleeve that corresponds to the gear ring 701. With the meshing gear 702, after placing the combined bracket on the base 1 and fixing the total station 8 on the mounting base 3, simply lifting or pressing down the mounting base 3 will drive the screw 704 to slide up and down, thereby causing the entire assembly formed by the connection between the screw sleeve 703 and the gear 702 to rotate. The gear ring 701 can rotate in this process. After releasing, the meshing relationship between the gear ring 701 and the gear 702 can also play a limiting role, preventing the screw sleeve 703 from rotating arbitrarily. Thus, the height of the mounting base 3 can be locked when no external force is applied.

[0021] The support rods 6 are arranged in a ring array. The top of the support rod 6 is rotatably connected to the middle plate 2 and the bottom is rotatably connected to the locking block 9. The base 1 is provided with several locking seats 10 that correspond one-to-one with the locking blocks 9. The angle of the support rod 6 can be fixed by aligning the locking blocks 9 with the locking seats 10. It is also convenient to disassemble and assemble. When not in use, the middle plate 2, the mounting base 3, the lifting mechanism 7 and the support rod 6 can be disassembled as a whole. Then the support rod 6 can be rotated inward and the mounting base 3 can be pressed down to the lowest point, which can greatly reduce the size of the device and facilitate transportation.

[0022] The air intake seat 5 is equipped with a sealing plug 11. The sealing plug 11 has a conical structure and is elastically connected to the air intake seat 5 by a spring. When the air pressure in the inflation assembly is too high, the sealing plug 11 will be pushed out to release the pressure, which can prevent the airbag 402 from being damaged due to over-inflation.

[0023] Example 2

[0024] Based on Embodiment 1, the insert rod 102 is provided with a slidable slide rod 103. Several side rods 104 arranged in a circular array are provided between the bottom end of the slide rod 103 and the bottom plate of the insert rod 102. The side rods 104 are made of elastic metal. A through groove is provided in the side wall of the insert rod 102 to cooperate with the side rods 104. During inflation, initially, the slide rod 103 blocks the through groove connecting the ventilation hood 401 and the insert rod 102. At this time, the gas entering the insert rod 102 will press the slide rod 103 down. During the process, the side rod 104 undergoes outward arching deformation due to compression at both ends. During this arching process, the side rod 104 passes through the through groove in the insertion rod 102 and inserts into the outer soil, thereby reinforcing the connection between the insertion rod 102 and the ground. This continues until the sliding rod 103 slides down to below the through groove connecting the ventilation hood 401 and the insertion rod 102. At this point, the gas inside the insertion rod 102 can enter the ventilation hood 401. Reinforcing the insertion rod 102 before inflating the inflation mechanism 4 avoids the problem of the insertion rod 102 loosening due to the pressure exerted on the ground by the inflation mechanism. The above-described embodiments only illustrate one implementation of the present invention, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
