Description

Technical Field

[0001] The present invention relates to the technical field of surveying and mapping equipment, and in particular to a geographic surveying and mapping sample collection device and a use method thereof. Background Art

[0002] Geographical surveying samples are a part of the geographical objects to be surveyed, which are extracted from the population and used to represent and infer the overall geographical characteristics of individuals or units. For example, when conducting a topographic survey of a city, it is impossible to measure every inch of land in the city in detail. Instead, some typical areas will be selected as samples. The topographic data of these sample areas can be used to infer the topographic conditions of the entire city.

[0003] Among the equipment for collecting samples in geographic surveying and mapping, the level is one of the most common devices. During the use of the level, it is necessary to adjust the foot screws at various positions to level the level. However, due to terrain and other reasons, the degree of extension and retraction of each foot screw after each level is leveled is different. After each use, if the foot screws are not "returned to the center", the next time the level is used directly, the foot screws may not be turned when they are adjusted directly. In fact, the travel of the foot screws has reached the limit position, which can easily lead to locking between the foot screws and their own shafts, making it difficult to adjust the foot screws.

[0004] However, after each use of the level, if you want to "return to the center" all the foot screws, you need to carefully check each foot screw and carefully "return to the center" the foot screws. In addition, there are "return to the center" instructions on the foot screws, and it depends entirely on the naked eye to judge. The entire inspection, adjustment, and judgment operation is very cumbersome.

[0005] In summary, how to quickly determine the position of the foot screws after the level is used, and how to conveniently determine the adjustment status of the foot screws when adjusting the foot screws, have become problems that need to be solved during the use of the level.

A fixed thread groove 1031 is provided at the center of the chassis 103. When in use, the level 1 is placed on the upper side of the tripod, and a hand-screw piece is installed from the bottom side of the tripod support platform. The hand-screw piece cooperates with the fixed thread groove 1031 to achieve a firm fixation of the chassis 103 of the level 1 on the tripod support platform (the fixing and installation method of the level 1 and the tripod piece belongs to the prior art and will not be repeated in this application).

[0038] Center disk 2 and magnetic ring 201: Combination Figure 2 , Figure 3 The center disk 2 is fixedly installed at the center position of the bottom side of the scale disk 101, and a magnetic ring 201 is embedded in the center disk 2.

[0039] Vertical sleeve 3: Combination Figure 1 , Figure 4 , Figure 5 , multiple vertical sleeves 3 are movably arranged on the chassis 103, and their distribution positions are aligned with the distribution positions of the foot screws 102. The top of the vertical sleeve 3 protrudes from the upper side of the chassis 103, and a limit ring 301 is provided on the outer ring side of the bottom. The chassis 103 is provided with multiple low-position installation grooves 1032, and a through-movement hole 1033 is provided just above each low-position installation groove 1032. The limit ring 301 is located in the low-position installation groove 1032, and the vertical sleeve 3 is limitedly installed at the position of the through-movement hole 1033 by the limit ring 301.

[0040] Magnetic sheet 4: Binding Figure 1 , Figure 2 , Figure 3 , a magnetic sheet 4 aligned with the magnetic ring 201 is embedded on the top side of the vertical sleeve 3, and the magnetic sheet 4 is a circular sheet. Let the ring width of the magnetic ring 201 be D1, let the diameter of the magnetic sheet 4 be D2, let the center disk 2 and the chassis 103 be parallel to each other as the standard zero value, let the angle range of the center disk 2 relative to the chassis 103 be [-α, α], then D1*cosα≥D2, to ensure that the magnetic ring 201 produces an effective repulsive force on the magnetic sheet 4, and no matter how the magnetic ring 201 is tilted, the magnetic sheet 4 is within the vertical projection range of the magnetic ring 201.

[0041] Double cone 5: Combination Figure 4 , Figure 5 , Figure 8The double cone member 5 is located in the mounting groove 302 on the bottom side of the vertical sleeve 3, and includes a main plate 501, an upper cone 502 and a lower cone 503.

The double cone member 5 is provided with a positioning screw hole 504 that vertically penetrates the main plate 501, the upper cone 502 and the lower cone 503. The diameters of the upper cone 502 and the lower cone 503 are smaller than the diameter of the main plate 501. The lower end of the upper spring 8 is sleeved on the outer periphery of the upper cone 502, and the upper end of the lower spring 9 is sleeved on the outer periphery of the lower cone 503, so as to achieve stable cooperation between the spring and the double cone member 5, and at the same time ensure the stability of the structure in a limited space, which is conducive to the screw connection of the screw member 7.

[0042] Card block 6: combination Figure 3 , Figure 4 , Figure 5 , Figure 7 , a plurality of block pieces 6 are fixedly embedded on the bottom side of the chassis 103, which are located directly below the vertical sleeve 3 and are clamped at the position of the low-position installation groove 1032, and the bottom side thereof is flush with the bottom side of the chassis 103. The block piece 6 includes an upper groove 601 with an opening facing upward, an inner cone 602 located at the center of the upper groove 601, and a rod body through hole 603 vertically penetrating the inner cone 602 and the bottom plate. The lower end of the lower spring 9 is sleeved on the periphery of the inner cone 602, and the screw member 7 is movably inserted at the position of the rod body through hole 603. The design of the inner cone 602 ensures that the screw member 7 is guided smoothly. Elastic clamping plates 604 are arranged on both sides of the block piece 6, and a limiting protrusion 605 is arranged on the outer side of the elastic clamping plate 604. The side wall surface of the low-position installation groove 1032 is provided with a clamping groove structure matched with the limiting protrusion 605 to ensure that the block piece 6 is installed firmly.

[0043] Screw 7: Combination Figure 4 , Figure 5 , Figure 8 , which consists of a plastic rod 701, a threaded structure 702 located at the upper section of the plastic rod 701, and a hexagonal groove 703 provided on the bottom side of the plastic rod 701. The screw member 7 is inserted into the inner periphery of the lower spring 9, and the upper end is screwed to the position of the positioning screw hole 504 of the double cone member 5. By inserting an inner hexagonal wrench into the hexagonal groove 703, the plastic rod 701 can be driven to rotate, thereby adjusting the position of the relevant components.

[0044] Spring component: Combined Figure 4 , Figure 5 , Figure 6 The upper spring 8 is installed between the top surface of the mounting groove 302 of the vertical sleeve 3 and the double cone member 5, and the lower spring 9 is installed between the double cone member 5 and the block member 6, which act together on the elastic adjustment mechanism of the device to assist in realizing the judgment and adjustment function of the position of the foot screw 102.

[0045] Embodiment 2: The present invention provides a method for using a geographic surveying and mapping sample collection device, and the specific method is as follows:

[0046] 1. Installation and debugging phase

[0047] First, fix the center plate 2 at the center position of the bottom side of the dial 101 as required, and install the vertical sleeve 3, upper spring 8, double cone 5, block 6 and screw 7 in sequence to ensure that each component is installed in the correct position and connected firmly.

[0048] Before the first use and in the subsequent regular maintenance process, the plurality of foot screws 102 are manually adjusted so that the positions of the foot screws 102 are centered, that is, in the middle position of their travel range.

[0049] Observe the current positions of the bottom ends of multiple screw members 7. If the bottom end of the screw member 7 is concave inwardly or convexly inwardly of the bottom side surface of the block member 6, use an Allen wrench to rotate the screw member 7 until the bottom end of the screw member 7 is flush with the bottom side surface of the block member 6 to ensure that the initial state of the device is normal.

[0050] ㈡ Post-measurement adjustment phase

[0051] After using the level 1 each time, remove the level 1 from the tripod, directly observe the chassis 103 of the level 1, and check the position of the bottom end of the screw member 7 relative to the bottom side of the chassis 103.

[0052] If the screw member 7 is obviously concave at the bottom side of the chassis 103, it indicates that the distance between the magnetic ring 201 and the magnetic sheet 4 at the current position is large, the repulsive force is reduced, and the screw member 7 moves up. At this time, the foot screw 102 at the corresponding position is rotated counterclockwise (because clockwise rotation increases the corresponding position of the foot screw 102, and counterclockwise rotation decreases it) until the bottom end of the screw member 7 is flush with the bottom side of the block member 6, and the adjustment of the foot screw 102 at this position is completed, so that it returns to the appropriate position.

[0053] If the screw member 7 is obviously protruding from the bottom side of the chassis 103, it means that the distance between the magnetic ring 201 and the magnetic sheet 4 at the current position is small, the repulsive force increases, and the screw member 7 moves down. At this time, the foot screw 102 at the corresponding position is rotated clockwise until the bottom end of the screw member 7 is flush with the bottom side of the block member 6, so that the foot screw 102 is correctly returned to its original position for the next use.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
