Description

Technical Field

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The device features a protective box and a protective plate mounted above a support frame, both connected to the support frame to form a protective cavity. The laser rangefinder body is located within this cavity. Multiple measurement ports are located on the protective box. The laser rangefinder body transmits a laser beam through these ports, which is reflected back by objects, thus measuring the distance to the ground. Simultaneously, an adjustment assembly is installed within the protective cavity, housing the laser rangefinder body. This assembly allows the laser rangefinder body to rotate at multiple angles. A drilling assembly is positioned between the support frames, connected to the support frames via a lifting assembly. This lifting assembly also allows for adjustment of the drilling depth. When measuring ground thickness, the drilling assembly can drill to the required depth. The operation of the adjustment assembly causes the laser rangefinder body to turn and align with the mounting sleeve in the drilling assembly. The mounting sleeve has a first reflector at its top. The adjustment shaft rotates smoothly with the cooperation of the adjustment gear and rack, causing the laser rangefinder body to turn, ensuring accurate alignment of the laser rangefinder with the mounting sleeve in the drilling assembly. The mounting sleeve has a first reflector at the top, which accurately reflects the laser emitted by the laser measuring instrument. By receiving and analyzing the reflected laser, the measuring device can calculate the thickness of the land; thus, through the cooperation of multiple components, the measurement of land distance and thickness can be achieved.

[0017] The annular and pressurized nozzles, installed between the support frames, play a crucial role in actual soil thickness measurement. The drill bit body in the drilling assembly passes through the annular nozzles, while the pressurized nozzle is located on one side of the drill bit body. Both the annular and pressurized nozzles are connected to the liquid supply assembly on the support frame, ensuring a stable liquid supply. Simultaneously, multiple atomizing nozzles are installed at the bottom of the annular nozzles. When measuring soil thickness on relatively dry ground, a large amount of dust is often generated. This dust not only affects the normal operation of the equipment, reducing its accuracy and lifespan, but also poses a serious threat to the health of operators. In this situation, the atomizing nozzles spray water mist, which effectively adsorbs dust particles in the air, causing them to settle, thus greatly reducing the harm of dust to the equipment and operators. At the same time, the pressurized nozzles moisten the soil, accelerating drilling into the soil, and also cool the drill bit body. During the drilling process, the drill bit body generates a lot of heat due to continuous friction with the soil. If it is not cooled down in time, it will cause the drill bit body to overheat and be damaged, affecting the normal progress of the measurement work.

[0018] A storage box is located on one side of the support plate. The rotatable cover and internal locking mechanisms of the storage box facilitate the storage and retrieval of the second reflector. When conducting land surveys in relatively open areas where reflective surfaces are often lacking, the second reflector can be removed from the storage box. Then, the telescopic rod and rotatable support legs connected to the second reflector are extended, positioning the second reflector in the desired location. This serves as a crucial reflector for the laser rangefinder, reflecting the laser beam. Through the reflection from the second reflector, the laser rangefinder accurately acquires the necessary data, ensuring the smooth progress of land surveying. Simultaneously, an observation eyepiece is located on one side of the second reflector. When long-distance operation is required, the operator does not need to approach the support frame. Through the observation eyepiece, the operator can observe the collimator target on the support frame from a distance. By observing the collimator target through the eyepiece, the operator can adjust the position of the second reflector to ensure accurate alignment with the laser rangefinder. This not only improves measurement efficiency but also ensures the accuracy of the measurement data, providing strong support for land surveying work. Attached Figure Description

[0035] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0036] Example 1: As Figures 1 to 14As shown, this utility model provides a switchable land planning and surveying device, mainly comprising a support frame 101 and a laser rangefinder body 21. The support frame 101 plays a supporting role in the entire device. A drilling assembly is installed inside the support frame 101, including a mounting sleeve 301. Connecting rods 302 are fixedly installed on both sides of the mounting sleeve 301. A lifting assembly is installed on the support frame 101, and the mounting sleeve 301 is connected to the lifting assembly through these two sets of connecting rods 302. This allows the mounting sleeve 301 to move stably up and down under the action of the lifting assembly, thereby adjusting the drilling depth according to actual measurement needs. A first reflector 303 is installed on the top of the mounting sleeve 301, which reflects the laser beam during subsequent land thickness measurement. A detachable protective box 41 and a protective plate 42 can be installed above the support frame 101. When the protective box 41 and the protective plate 42 are installed in place, they form a protective cavity. The protective cavity provides a working environment for the laser rangefinder body 21. The laser rangefinder body 21 is placed inside this protective cavity to prevent potential damage from external factors. An adjustment assembly is provided on the protective plate 42, on which the laser rangefinder body 21 is mounted. Through the adjustment assembly, the laser rangefinder body 21 can rotate at multiple angles, thereby enabling the measurement of ground distance and thickness. The laser rangefinder body 21 can be a Nikon COOLSHOT PRO laser rangefinder. The protective box 41 has multiple sets of measurement ports, providing channels for the laser rangefinder body 21 to emit and receive laser beams. Simultaneously, the support frame 101 has a dedicated light-transmitting hole 102 corresponding to one set of measurement ports, ensuring that the laser beam can propagate smoothly through the measurement ports and the light-transmitting hole 102. The first reflector 303, located below the light-transmitting hole 102, accurately reflects the laser emitted by the laser rangefinder body 21 during ground thickness measurement. Meanwhile, a control panel 22 is also provided on one side of the support frame 101. The control panel 22 provides a convenient operating interface for the operator, allowing control of various functions of the entire measuring device. The control panel 22 can be a Mitsubishi GOT2000 GT2507-WTBD control panel. Through the control panel 22, the operator can easily start and stop the drilling assembly, adjust the height of the lifting assembly, control the measurement mode of the laser rangefinder body 21, and adjust its angle, etc.

[0037] like Figure 2 , Figure 3 , Figure 4As shown, the drilling assembly also includes a drilling motor 304 and a drill bit body 305. A mounting housing 306 is located below the mounting sleeve 301, and the mounting housing 306 and the mounting sleeve 301 are detachably connected, forming a mounting cavity when connected. This mounting cavity provides a stable mounting space for the drilling motor 304. The drilling motor 304 is located within the mounting cavity and is secured between multiple mounting blocks 307, ensuring stability during operation and preventing displacement due to vibration. Simultaneously, a certain gap is formed between the drilling motor 304 and the mounting sleeve 301, providing space for heat dissipation and facilitating installation and disassembly. Mounting holes are provided on both the drilling motor 304 and the mounting blocks 307, through which mounting bolts pass. The drill bit body 305, located below the drilling motor 304, is a key component for realizing the drilling function. A drill hole is provided on the mounting housing 306. One end of the drill bit body 305 passes through this drill hole and is connected to the shaft end of the drilling motor 304. When the drilling motor 304 starts, its powerful force is transmitted to the drill bit body 305 through the shaft end, enabling the drill bit body 305 to rotate at high speed and drill the required hole in the ground. When it is necessary to measure the soil thickness, the drilling motor 304 drives the drill bit body 305 to drill downwards until the required depth is reached. During this process, the mounting sleeve 301 is connected to the lifting assembly through the connecting rod 302, and the drilling depth can be adjusted as needed.

[0038] An annular nozzle 43 is installed between the support frames 101. Multiple atomizing nozzles 44 are installed at the bottom of the annular nozzle 43 to ensure a wide coverage area for the sprayed water mist. The drill bit body 305 passes through the annular nozzle 43, allowing the atomizing nozzles 44 to directly act on the drill bit body 305 and its surrounding area during drilling. A pressurized nozzle 45 is also installed below the annular nozzle 43, located on one side of the drill bit body 305 and firmly connected to the support frame 101. The pressurized nozzle 45 provides additional assistance during drilling. When drilling on relatively dry and hard soil, the pressurized nozzle 45 can spray high-pressure water to help the drill bit body 305 penetrate the soil more quickly, improving drilling efficiency. Meanwhile, heat dissipation grooves 308 are provided on both sides of the mounting sleeve 301. Heat-conducting elements 309 are installed within the heat dissipation grooves 308, with one side of the heat-conducting element 309 contacting the drilling motor 304. During operation, the drilling motor 304 generates a large amount of heat. If this heat is not dissipated in time, it may affect the motor's performance and lifespan. The heat-conducting component 309 can conduct the heat generated by the drilling motor 304 away. On the other side of the heat-conducting component 309, multiple sets of heat dissipation fins 310 are provided. The heat dissipation fins 310 can increase the heat dissipation area and improve heat dissipation efficiency, ensuring that the drilling motor 304 remains within a suitable temperature range during operation. A support platform 103 is provided on the support frame 101. The support platform 103 provides a stable mounting platform for the liquid supply assembly. The liquid supply assembly includes a water pump 51, which is installed at the bottom of the support platform 103. The water pump 51 is connected to the annular nozzle 43 and the pressurized nozzle 45 via connecting pipes. During operation, the water pump 51 delivers liquid to the annular nozzle 43 and the pressurized nozzle 45. For the annular nozzle 43, the liquid supplied by the water pump 51 is sprayed out through the atomizing nozzle 44, forming a fine water mist. When drilling on dry ground, this water mist effectively adsorbs dust particles in the air, reducing the harm of dust to equipment and operators. For the pressurized nozzle 45, the high-pressure water flow provided by the water pump 51 assists in the drilling operation and also cools the drill bit body 305, ensuring smooth drilling.

[0039] like Figure 2 , Figure 11 , Figure 13As shown, the liquid supply assembly also includes a storage tank 52 and a connector 53. A limiting sleeve 104 is provided above the support platform 103 to hold the storage tank 52 in place. The storage tank 52 serves as a liquid storage container, providing a continuous liquid supply to the annular nozzle 43 and the pressurized nozzle 45. A liquid outlet pipe 105 is installed on one side of the storage tank 52, with a valve at one end. When drilling operations are required, the valve is opened, allowing the liquid in the storage tank 52 to flow out through the outlet pipe 105. The connector 53 is located on one side of the storage tank 52 and is securely connected to the support platform 103. The connector 53 connects the storage tank 52 and the water pump 51. One end of the connector 53 is connected to the valve, and the other end is connected to the water pump 51 via a connecting pipe. This ensures that the liquid can flow smoothly from the storage tank 52 to the water pump 51, and then be delivered by the water pump 51 to the annular nozzle 43 and the pressurized nozzle 45. The connector 53 has an internally threaded tube 54 at its top, forming a three-way pipe structure that allows for more flexible liquid flow, which can be adjusted according to actual needs. A sealing plug 55 is secured within the internally threaded tube 54, effectively preventing liquid leakage. Simultaneously, the connector 53 is also equipped with a stabilizing cover 56, with the internally threaded tube 54 located within it. This allows for easy removal of the sealing plug 55 outdoors, enabling the mineral water bottle to be directly clamped into the internally threaded tube 54, providing a flexible emergency liquid supply method for measurement work in special environments such as the field.

[0040] Figure 2 As shown, the lifting assembly includes two sets of lead screws 61. Two sets of first bearings are provided on both sides of the support frame 101. The two ends of the lead screws 61 pass through the first bearings, allowing them to rotate stably. A connecting rod 302 has a connecting through hole, through which the lead screws 61 pass. The mounting sleeve 301 is slidably connected to the two sets of lead screws 61, and the rotation of the lead screws 61 enables the mounting sleeve 301 to move up and down. Each lead screw 61 is equipped with a transmission wheel 62, and the two sets of transmission wheels 62 are connected by a transmission belt 63. This ensures that the two sets of lead screws 61 can rotate synchronously. A lifting motor 64 is provided on the support frame 101, and the shaft end of the lifting motor 64 is connected to one set of lead screws 61. When the lifting motor 64 starts, it drives the connected lead screw 61 to rotate. Through the action of the transmission wheel 62 and the transmission belt 63, the other set of lead screws 61 also rotates synchronously, thereby achieving smooth lifting and lowering of the mounting sleeve 301.

[0041] like Figure 8 , Figure 9As shown, the adjustment assembly includes an adjustment shaft 71 and an adjustment gear 72. Two sets of connecting plates 46 are provided on the protective plate 42, and second bearings are installed on the connecting plates 46. The adjustment shaft 71 passes through these two sets of second bearings, ensuring stable rotation of the adjustment shaft 71. A fixing plate 73 is provided on the adjustment shaft 71, and the laser rangefinder body 21 is located between the two sets of connecting plates 46. Fixing grooves 74 are provided on both sides of the fixing plate 73, and two sets of fixing sliders 23 are provided at the bottom of the laser rangefinder body 21. The fixing sliders 23 can be locked in the fixing grooves 74, so that the laser rangefinder body 21 and the fixing plate 73 are detachably connected, which facilitates the maintenance and replacement of the equipment. The adjustment gear 72 is sleeved on one end of the adjustment shaft 71, and through cooperation with other components, the angle of the laser rangefinder body 21 can be adjusted.

[0042] The adjustment assembly also includes a limiting slide rail 75 and an electric cylinder 76. The limiting slide rail 75 is firmly connected to the protective plate 42. A limiting slider 77 is slidably mounted on the limiting slide rail 75, and an adjusting rack 78 is installed on the limiting slider 77. The adjusting rack 78 meshes with the adjusting gear 72. When it is necessary to adjust the angle of the laser rangefinder body 21, the electric cylinder 76 is activated. The electric cylinder 76, mounted on the protective plate 42, is located on one side of the limiting slide rail 75. A connecting plate 79 is provided below the limiting slide rail 75. One end of the connecting plate 79 is connected to the limiting slider 77 by a screw, and the other end is sleeved on the shaft end of the electric cylinder 76. The extension and retraction movement of the electric cylinder 76 drives the connecting plate 79 to move, thereby causing the limiting slider 77 to slide on the limiting slide rail 75. Through the meshing transmission of the adjusting rack 78 and the adjusting gear 72, the adjusting shaft 71 is driven to rotate, thereby realizing the adjustment of the angle of the laser rangefinder body 21. A light-shielding sleeve 47 is provided at one end of the measuring port, and one set of light-shielding sleeves 47 passes through the light-transmitting hole 102. A filter lens is provided inside the light-shielding sleeve 47. These filter lenses can effectively filter out external stray light interference, ensuring that the laser signal received by the laser rangefinder body 21 is more accurate.

[0043] like Figure 2 , Figure 10As shown, a placement box 106 is provided on one side of the support frame 101. A placement cover 107 is rotatably mounted on the placement box 106. When the placement cover 107 is closed, a placement cavity is formed. A second reflector 108 is placed inside the placement cavity. When long-distance measurement is required or there are no suitable reflective objects nearby, the second reflector 108 can reflect the laser beam. A telescopic rod 109 is provided at the bottom of the second reflector 108. Multiple sets of rotatable support feet are provided at one end of the telescopic rod 109. By adjusting the length of the telescopic rod 109 and the angle of the support feet, the second reflector 108 can be stably placed in the desired position. Multiple sets of fixing buckles 110 are provided inside the placement box 106. The telescopic rod 109 can be secured to these fixing buckles 110, ensuring that the second reflector 108 and the telescopic rod 109 can be stored away when not in use. An observation eyepiece 111 is provided on one side of the second reflector 108. The observation eyepiece 111 is rotatably connected to the second reflector 108. The operator can observe the crosshair target 112 set on the top of the support frame 101 from a distance through the observation eyepiece 111, thereby adjusting the position of the second reflector 108 so that it can accurately reflect the laser emitted by the laser rangefinder body 21.

[0044] Example 2: Based on the switchable land use planning and surveying device provided in Example 1 of this application, Example 2 of this application proposes a switchable land use planning and surveying device. This Example 2 is merely a preferred embodiment of Example 1, and its implementation will not affect the independent implementation of Example 1. The Example 2 of this utility model will be further described below.

[0045] like Figures 5 to 7 As shown, an annular nozzle 43 is arranged between the support frames 101. Multiple atomizing nozzles 44 are installed at the bottom of the annular nozzle 43 to ensure a wide coverage area for the sprayed water mist. The drill bit body 305 passes through the annular nozzle 43, allowing the atomizing nozzles 44 to directly act on the drill bit body 305 and its surrounding area during drilling. A pressurized nozzle 45 is also arranged below the annular nozzle 43, located on one side of the drill bit body 305 and firmly connected to the support frame 101. The pressurized nozzle 45 provides additional assistance during drilling. When drilling on relatively dry and hard soil, the pressurized nozzle 45 can spray high-pressure water to help the drill bit body 305 penetrate the soil more quickly, improving drilling efficiency. Meanwhile, heat dissipation grooves 308 are provided on both sides of the mounting sleeve 301. Heat-conducting elements 309 are installed within the heat dissipation grooves 308, with one side of the heat-conducting element 309 contacting the drilling motor 304. The drilling motor 304 generates a lot of heat during operation. If it is not cooled in time, it may affect the performance and life of the motor.

[0046] Meanwhile, multiple sets of guide ribs 311 are provided on both sides of the mounting sleeve 301. These guide ribs 311 not only strengthen the structural strength of the mounting sleeve 301, but also guide the flow of liquid. Two sets of water inlet chambers 312 are provided on the mounting sleeve 301, and multiple sets of water outlet holes 313 are also provided on the mounting sleeve 301, located above the guide ribs 311. The water inlet chambers 312 are connected to the outside through the water outlet holes 313, allowing the liquid to flow downwards along the guide ribs 311 and leave on the surface of the heat-conducting component 309, thereby carrying away heat from the heat-conducting component 309 and achieving a cooling function. A support platform 103 is provided on the support frame 101, providing a stable mounting platform for the liquid supply assembly. The water pump 51 in the liquid supply assembly is installed at the bottom of the support platform 103. Two sets of liquid inlet pipes 314 are provided above the mounting sleeve 301, and the liquid inlet pipes 314 are connected to the water inlet chambers 312. The water pump 51 is connected to the annular nozzle 43, the pressurized nozzle 45, and two sets of inlet pipes 314 via connecting pipes. During operation, the water pump 51 can deliver liquid to various required parts, providing atomizing water for the annular nozzle 43, providing high-pressure water flow for the pressurized nozzle 45, and also providing circulating liquid for heat dissipation of the mounting sleeve 301.

[0047] The difference between this embodiment and embodiment one is that two sets of water inlet chambers 312 are provided on the mounting sleeve 301, and are connected to the water pump 51 through the liquid inlet pipe 314, which can smoothly transport the water in the storage tank 52 into the water inlet chambers 312, and then flow out downward through two sets of water outlet holes 313. At the same time, multiple sets of guide ribs 311 are provided on both sides of the mounting sleeve 301. When the water flows out, it will flow downward along the guide ribs 311. Due to the guiding effect of the guide ribs 311, the water will flow over the surface of the heat-conducting component 309. In this process, the heat on the heat-conducting component 309 can be effectively removed, thereby realizing the cooling function of the drilling motor 304 and ensuring the stability and reliability of the equipment during operation. The other conditions are the same as in embodiment one, so they will not be described again in this embodiment.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
