[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1 to Figure 8 The present invention provides a technical solution, which specifically includes the following embodiments:

[0039] Embodiment 1:

[0040] A positioning measurement device for land planning comprises a measuring instrument housing 1 and a measuring instrument 2, wherein the measuring instrument housing 1 and the measuring instrument 2 are detachably fixedly connected, a water cooling assembly 3 is fixed on the measuring instrument 2, and the water cooling assembly 3 is used to cool the measuring instrument 2 body, and the water cooling assembly 3 comprises a heat dissipation pipe 30, wherein the heat dissipation pipe 30 is wound and fixed on the outer wall of the measuring instrument 2, one end of the heat dissipation pipe 30 is connected to a water pump 31, and a nozzle 32 is installed at the other end of the heat dissipation pipe 30, wherein the nozzle 32 is of a multi-hole design and is equipped with an electromagnetic valve for controlling the flow rate of water, and the water of the nozzle 32 flows back into a water reservoir 33 and is sprinkled onto an air cooling assembly 4, wherein the air cooling assembly 4 is arranged around the measuring instrument 2, and is used for air flow and heat dissipation, and the air cooling assembly 4 is drivingly connected to an oscillating assembly 5;

[0041] The oscillation component 5 is used to disperse the water molecules by vibration, and includes oscillators 50 . A plurality of oscillators 50 are arranged in a ring and are located at the air outlet of the air cooling component 4 .

[0042] During operation, when the outside temperature is too high and the measuring instrument 2 is difficult to dissipate heat, water is added to the water reservoir 33, and the water pump 31 is started. Water is added to the heat dissipation pipe 30, and the heat is taken away by the heat dissipation pipe 30, so that the heat dissipation pipe 30 cools the measuring instrument 2. When the outside temperature is still very high, the air cooling component 4 and the oscillation component 5 are started. The air cooling component 4 blows the air containing water vapor surrounding the measuring instrument 2 to the outside, and then the water vapor is vibrated and dispersed through the oscillator 50 and diffused around the measuring instrument 2.

[0043] The present invention dissipates heat from the body of the measuring instrument 2 through a water cooling component 3, and further provides an air cooling component 4 and an oscillation component 5. The air cooling component 4 blows air containing water vapor to the outside, and then disperses the water vapor through vibration of an oscillator 50, rapidly diffuses around the measuring instrument 2, thereby improving the efficiency of taking away heat without affecting observation. In addition, the air blown to the outside lowers the ambient temperature and reduces the generation of heat waves, so that the measuring instrument 2 can work normally and obtain accurate data.

[0044] The water reservoir 33 has a water inlet and a water outlet, the water outlet is fixedly connected to the water pump of the water pump 31, and the output pipe of the water pump 31 is detachably fixedly connected to one end of the heat dissipation pipe 30 for water inlet.

[0045] Among them, refer to Figure 1 and Figure 8The measuring instrument 2 is provided with a beam processor inside, an eyepiece 11 and an objective lens 12 are provided at both ends, a shielding cover 13 is fixed on the objective lens 12, the measuring instrument 2 is bolted to one end of a connecting rod 14, the other end of the connecting rod 14 is fixedly connected to the measuring instrument housing 1, a slewing bearing 15 is installed at the bottom of the measuring instrument housing 1, and the slewing bearing 15 is fixed to a support frame. The present invention makes the measuring instrument housing 1 and the measuring instrument 2 detachable, and can connect a variety of support frames through the slewing bearing 15, such as a commonly used multi-support leg structure, to achieve a positioning support function.

[0046] Among them, the nozzle 32 is rotatable, and technical personnel in this field can judge whether to aim it at the fan blades 46 according to the actual external temperature. For example, when the external temperature is not very high and there is no need to start the air cooling component 4, the nozzle 32 is not aimed at the fan blades 46, and the return water directly enters the water reservoir 33, relying on the water cooling component 3 to dissipate heat for the measuring instrument 2.

[0047] The water reservoir 33 is provided with a liquid level gauge, and when the water level drops to a certain level, water is added from the water inlet.

[0048] Among them, refer to Figure 7 The housing of the measuring instrument 2 is provided with a plurality of annular grooves 81 , the heat dissipation pipe 30 is arranged in the grooves 81 , a heat sink is arranged between two grooves 81 , and the shape of the grooves 81 matches the heat dissipation pipe 30 .

[0049] The present invention can improve the heat dissipation efficiency by winding the heat dissipation tube 30 and arranging the groove 81 matched therewith, so that the measuring instrument 2 can be cooled down quickly.

[0050] The heat dissipation pipe 30 includes a plurality of rectangular pipes 301 and a connecting pipe 302 . The cross-sections of the rectangular pipes 301 and the connecting pipes 302 are both semicircular. Two rectangular pipes 301 are connected and communicated with each other through the connecting pipe 302 .

[0051] The water supply method of the present invention can quickly make the water flow to and out of the heat dissipation pipe 30, thereby improving the efficiency of heat exchange.

[0052] Among them, refer to Figure 7 The water inlet direction is from bottom to top, the first connecting pipe 302 is arranged in the middle of the top of the first rectangular tube 301 and the second rectangular tube 301, the second connecting pipe 302 is arranged in the middle of the bottom of the second rectangular tube 301 and the third rectangular tube 301, and so on, to complete the arrangement of the heat dissipation tube 30.

[0053] Among them, the rectangular tube 301 and the connecting tube 302 are set in a shape-dependent manner. When the shell of the measuring instrument 2 is circular, the rectangular tube 301 and the connecting tube 302 are set in an arc shape and wrapped around the surface of the measuring instrument 2. Those skilled in the art can set the shape of the heat dissipation tube 30 according to actual conditions.

[0054] As a further explanation of this embodiment, refer to Figure 3 and Figure 6 The air cooling component 4 includes a first gear ring 40, which is meshed with a gear 41. The gear 41 is coaxially fixed with the output shaft of the motor 42. The motor 42 is fixed on a first support plate 44. The first gear ring 40 is connected to the first support plate 44 by bearings. A plurality of arc rods 45 are fixed on the surface of the first gear ring 40, and a fan blade 46 is fixed on each of the arc rods 45. The fan blade 46 overlaps with the water retaining net 47 when rotating. The water retaining net 47 is arc-shaped and has a plurality of leakage holes evenly arranged on the surface. The water retaining net 47 is fixed on the top of the water reservoir 33, and the water reservoir 33 is fixed to the first support plate 44.

[0055] During operation, the motor 42 is started, so that the gear 41 drives the first gear ring 40 to rotate, thereby rotating the blades 46 on the arc rod 45. While the blades 46 rotate, they come into contact with the water in the water reservoir 33, adhere to the surface of the blades 46 or throw a part of it into the air, and are brought to the outside by the rotating exhaust air.

[0056] The present invention sets an air cooling component 4, arranges the fan blades 46 in a ring shape, generates a whirlwind, quickly entrains the air, and increases the air flow rate. The fan blades 46 are used to dissipate water to moisten the air, lowering the air temperature and improving the heat exchange efficiency of the heat pipe 30. The temperature of the measuring instrument 2 is quickly reduced to a working state capable of measurement, and the ambient temperature is also reduced.

[0057] The water level in the water reservoir 33 is higher than the lowest point of the arc-shaped water retaining net 47 , and the water level is lower than the highest point of the arc-shaped water retaining net 47 .

[0058] The present invention allows a portion of the water retaining net 47 to be immersed in water, so that the fan blades 46 can dip into the water while the water retaining net 47 slightly contacts the fan blades 46, thereby preventing a large amount of water from being scraped out of the water reservoir 33. Figure 6 As shown, the contact state between the lowest blade 46 and the water retaining net 47.

[0059] The water retaining net 47 is made of rubber and is elastic, so that when the fan blades 46 pull the water retaining net 47 during rotation, the water retaining net 47 is not easily damaged. Moreover, the tension of the lightweight and elastic material in the water makes it easy to float, avoiding splashing water.

[0060] When the water from the nozzle 32 enters the water reservoir 33, a part of it is sprinkled onto the fan blades 46 in the air cooling component 4, so that the fan blades 46 carry away the water and sprinkle it into the air during the rotation process, cooling the water while causing water molecules to condense in the air to moisten the air.

[0061] The power modules of the motor 42 and the water pump 31 include a battery, an electric control module, and a wireless communication module, and the wireless communication module is wirelessly connected to a user terminal.

[0062] The present invention allows the user to directly control the rotation speed of the motor 42 and the water pump 31 through the wireless communication module, thereby adjusting the cooling efficiency.

[0063] Among them, those skilled in the art can set the transmission ratio of the first gear ring 40 and the gear 41 according to actual needs. In order to display the structure more intuitively, the dimensions shown in the figure are only for reference.

[0064] As a further explanation of this embodiment, refer to Figure 3~Figure 5 The oscillation assembly 5 also includes a rotating mechanism 6, which includes a circular ring 61, which is fixed to the arc rod 45, and a plurality of slide rails 62 are fixed on the circular ring 61. A first slider 63 is provided on the slide rail 62 for moving along the slide rail, and one end of the first slider 63 is connected to a roller 64 bearing, and the roller 64 overlaps the inner wall of the wave ring 65, and the wave ring 65 is fixed to a second support plate 66, and the other end of the first slider 63 is fixed to a convex block 67, and the convex block 67 intermittently overlaps the oscillator 50.

[0065] During operation, the air cooling component 4 and the oscillation component 5 can be linked, and the ring 61 can rotate under the drive of the arc rod 45, so that the first slider 63 can rotate. During the rotation, the roller 64 on the first slider 63 moves along the wave circle 65, so that the first slider 63 can move reciprocatingly radially, thereby allowing the convex block 67 at the other end of the first slider 63 to move reciprocatingly radially.

[0066] The first sliding block 63 is fixedly connected to the first spring 68 , and the other end of the first spring 68 is fixed to the slide rail 62 .

[0067] The present invention enables the first sliding block 63 to quickly reset when moving in the radial direction, thereby improving the oscillation efficiency.

[0068] The structures composed of two groups of the slide rails 62 , the first slider 63 , the roller 64 , the convex block 67 , and the first spring 68 are symmetrically arranged on both sides of the circular ring 61 .

[0069] The present invention can improve oscillation efficiency and stability.

[0070] The inner wall of the wave ring 65 is wave-shaped, with wave crests and wave troughs, so that the roller 64 can move radially back and forth when moving along the wave ring 65.

[0071] As a further explanation of this embodiment, refer to Figure 3~Figure 5 The oscillator 50 includes a rotating shaft 501, and the rotating shaft 501 is intermittently overlapped with the convex block 67. The two ends of the rotating shaft 501 are respectively connected to an elastic component 7 by bearings. The elastic component 7 includes a wire bundle shaft 70, and the wire bundle shaft 70 is connected to the rotating shaft 501 by bearings. One end of a plurality of elastic ropes 71 is annularly fixed on the surface of the wire bundle shaft 70, and the other end of the elastic rope 71 is fixed on a guide ring 72. The guide ring 72 is fixedly connected to one end of a first fixed rod 73, and the other end of the first fixed rod 73 is fixed to the ring 61.

[0072] During operation, the convex block 67 can move radially back and forth. When the small head of the convex block 67 overlaps the rotating shaft 501 and transitions to the large head of the convex block 67 overlapping the rotating shaft 501, the wire bundle shaft 70 gradually deviates from its original position and is squeezed to one side. When the large head of the convex block 67 does not overlap the rotating shaft 501, the wire bundle shaft 70 is reset, and the twisted and tensioned elastic rope 71 rebounds instantly and produces multiple vibrations, repeatedly oscillating the water vapor in the air and splitting it into smaller molecules. With the help of the air blowing of the air cooling component 4, it quickly diffuses into the surrounding environment, lowers the ambient temperature, reduces the generation of heat waves in front of the measuring instrument 2, and improves the accuracy of the measurement.

[0073] Among them, an elastic rope 71 can be made of multiple ropes twisted together to increase the incidence of vibration.

[0074] As a further explanation of this embodiment, refer to Figure 3~Figure 4 as well as Figure 7 Two groups of guide blocks 91 are symmetrically arranged on the inner wall of the measuring instrument housing 1. The guide blocks 91 are slidably connected to the guide grooves 92. The guide grooves 92 are penetrated and opened on the first support plate 44 and the second support plate 66. One end of the guide block 91 is fixed with a limit block 93, and the other end of the guide block 91 is provided with an oblique threaded hole 94. The oblique threaded hole 94 is threadedly connected with a bolt 95, and the bolt 95 is against the limit groove 96 opened on the second support plate 66.

[0075] The present invention makes the air cooling component 4 and the oscillation component 5 and the measuring instrument 2 be of separate design, which is convenient to carry and use, and can be quickly disassembled when in use.

[0076] As a further explanation of this example, refer to Figure 1~Figure 3 Two symmetrically arranged handles 16 are fixed on the measuring instrument housing 1 .

[0077] The present invention can ensure the stability of measurement and improve the convenience of carrying during measurement.
