[0005] Therefore, the technical problem to be solved by the present invention is that the existing snow density detection device mostly performs average density detection on a piece of snow during use, which is inconvenient to perform layered density detection in thick snow.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: a device for rapid on-site detection of the layer density of thick natural snow, comprising a plate and a detection mechanism installed above the plate, wherein the detection mechanism comprises a moving component and a detection component;

[0008] The detection assembly includes a mass scale, the top of the plate and the mass scale are fixed to each other, and the center lines of the mass scale and the plate coincide with each other;

[0009] The gear train is fixed on the left side of the gear train, and the gear train is fixed on the right side of the gear train, and the gear train is fixed on the left side of the gear train. The lifting of the lifting gear is increased with the increase of the number of lifting gears, and the reduction gear rotation is increased with the increase of the number of lifting gears, and the reduction gear rotation is increased with the increase of the number of lifting gears.

[0010] Preferably, the mounting plate forms a rotating structure with the plate body through the cooperation between the first rotating shaft and the first motor, and the mounting plate forms a sliding structure with the plate body through the cooperation between the balancing rotating shaft and the balancing sliding groove.

[0011] Preferably, the vertical tooth plate forms a telescopic structure through the third hydraulic rod and the mounting plate, the gears all form a rotating structure through the vertical tooth plate, the connecting rod forms a rotating structure through the cooperation between the second rotating shaft and the gear, and the connecting rods are symmetrical with each other about the center line of the vertical tooth plate.

[0012] Preferably, the anti-slip ring and the gripping clamp are fixed to each other, and the centers of the circles of the anti-slip ring and the cup body coincide with each other.

[0013] Preferably, the telescopic plate forms a telescopic structure with the plate body through the cooperation between the first hydraulic rod and the mounting groove, and the center lines of the telescopic plate and the plate body coincide with each other.

[0014] Preferably, the middle fixed plate forms a folding structure with the telescopic plate through the cooperation between the second hydraulic rod and the third rotating shaft, the triangular base plate and the telescopic plate are rotatably connected, the triangular base plate is an arrow-shaped structure, and the fixed sleeve rod and the triangular base plate are fixed to each other.

[0015] Preferably, the third pulley forms a transmission structure with the first pulley through a driving belt, the second pulley forms a transmission structure with the third pulley, and the fourth pulley forms a transmission structure with the second pulley through a driving belt.

[0016] Preferably, the top fixed plate and the sampling sleeve are fixed to each other, the top fixed plate forms a lifting structure through the gear rod and the triangular bottom plate, the top fixed plate and the gear rod are engaged with each other, the sizes of the feeding rod and the sampling sleeve match each other, and the feeding rod forms a rotating structure through the third motor.

[0017] Preferably, the snow is taken out through the sampling sleeve, and then the fixed sleeve rod, the middle fixed plate and the triangular bottom plate are fixed to each other, and the sampling sleeve is sleeved inside the fixed sleeve rod and can slide up and down. Therefore, when the gear rod is driven to rotate, the top of the gear rod and the top fixed plate are fixed to each other, and the top fixed plate and the sampling sleeve are fixed to each other, and then the bottom of the gear rod is installed on the triangular bottom plate. Therefore, when the gear rod rotates, it will drive the top fixed plate to rise and fall inside the device, so as to adjust the height of the sampling sleeve inside the device, and then the third motor The feeding rod at the bottom is driven to rotate inside the device. During testing, the sampling sleeve is first installed at the position to be tested, and then the sampling sleeve is driven downward to drill the snow. When the device descends to the height to be tested, the feeding rod will discharge all the snow above the height to be tested through the snow outlet pipe. After complete discharge, the device continues to move downward one unit height, and then the feeding rod will discharge all the snow inside the sampling sleeve. The snow obtained by the feeding rod is snow per unit volume. At this time, the density of snow at different levels can be obtained by measuring the weight of the obtained snow.

[0018] The present invention has the following beneficial effects:

[0019] During use of the present invention, the first motor drives the first rotating shaft to rotate inside the device. Since the mounting plate and the first rotating shaft are fixed to each other, the mounting plate will rotate inside the device through the first rotating shaft. During rotation, the angle of the limit ring clamped inside the clamp on the right side of the mounting plate inside the device can be adjusted, so that the snow discharged from the snow outlet pipe can be adjusted to the top of the mass scale for weighing, so that the density of the accumulated snow can be detected. At the same time, when the mounting plate rotates, the balancing shaft at the bottom will slide inside the balancing slide groove to improve the balance of the mounting plate during rotation and improve the stability of the device.

[0020] During use of the present invention, the third hydraulic rod drives the vertical tooth plate to extend and retract inside the device. When the vertical tooth plate extends and retracts, it can drive the meshing gears on both sides to rotate inside the device. When rotating, the internal second rotating shaft will also be driven to rotate inside the device. Since the connecting rod and the second rotating shaft are fixed to each other, the connecting rod will also rotate inside the device, thereby adjusting the angle of the connecting rod inside the device, thereby adjusting the angle of the right-side clamp inside the device, making it convenient to clamp the limit ring inside the clamp for fixation, so that the limit ring can be lifted.

[0021] During use of the present invention, the second hydraulic rod adjusts the position of the middle fixed plate on the right side inside the device by telescoping. Since the third rotating shaft is installed on the left and right sides of the second hydraulic rod, the middle fixed plate will rotate inside the device through the third rotating shaft. At the same time, the triangular bottom plate and the telescopic plate are rotatably connected. Therefore, the triangular bottom plate can be folded with the telescopic plate inside the device by the second hydraulic rod, further reducing the volume of the device when it is stored and improving the flexibility of the device during use.

[0022] During use, the fixed sleeve, the middle fixed plate, and the triangular base plate are all fixed to each other, and the sampling sleeve is sleeved inside the fixed sleeve and can slide up and down. Therefore, when the gear rod is driven to rotate, the top of the gear rod is fixed to the top fixed plate, and the top fixed plate is fixed to the sampling sleeve. Then, the bottom of the gear rod is installed on the triangular base plate. Therefore, when the gear rod rotates, it drives the top fixed plate to rise and fall inside the device, thereby adjusting the height of the sampling sleeve inside the device. Then, the third motor drives the bottom feeding rod to rotate inside the device. During testing, the sampling sleeve is first installed at the position to be tested, and then the sampling sleeve is driven downward to drill snow. When the device descends to the height to be tested, the feeding rod drains all the snow above the test height through the snow discharge pipe. After complete drainage, the device continues to move downward one unit height, and then the feeding rod drains all the snow inside the sampling sleeve. The snow collected by the feeding rod is the snow per unit volume. At this time, the weight of the collected snow is measured to obtain the density of snow at different levels.

[0040] Example 2

[0041] like Figure 1-9 As shown, this embodiment is based on the previous embodiment, and differs from the previous embodiment in that this embodiment provides a rapid on-site detection device for the density of natural snow layers of great thickness, specifically.

[0042] The mounting plate 8 forms a rotating structure with the plate body 1 through the cooperation between the first rotating shaft 6 and the first motor 5, and forms a sliding structure with the plate body 1 through the cooperation between the balancing rotating shaft 17 and the balancing slide 7. During use, the first motor 5 drives the first rotating shaft 6 to rotate inside the device. Since the mounting plate 8 and the first rotating shaft 6 are fixed to each other, the mounting plate 8 will rotate inside the device through the first rotating shaft 6. During rotation, the angle of the limiting ring 16 clamped inside the clamp 13 on the right side of the mounting plate 8 inside the device can be adjusted, which is convenient for adjusting the snow discharged from the snow outlet pipe 34 to the top of the mass scale 2 for weighing, so that the density of the accumulated snow can be detected. At the same time, when the mounting plate 8 rotates, it will slide inside the balancing slide 7 through the balancing rotating shaft 17 at the bottom to improve the balance of the mounting plate 8 during rotation and improve the stability of the device.

[0043] The vertical tooth plate 9 forms a telescopic structure between the third hydraulic rod 39 and the mounting plate 8, and the gears 10 all form a rotating structure through the vertical tooth plate 9. The connecting rod 12 forms a rotating structure through the cooperation between the second rotating shaft 11 and the gear 10. The connecting rods 12 are symmetrical with each other about the center line of the vertical tooth plate 9. During use, the third hydraulic rod 39 drives the vertical tooth plate 9 to extend and retract inside the device. When the vertical tooth plate 9 extends and retracts, it can drive the meshing gears 10 on both sides to rotate inside the device. When rotating, the second rotating shaft 11 inside the device will also be driven to rotate inside the device. Since the connecting rod 12 and the second rotating shaft 11 are fixed to each other, the connecting rod 12 will also rotate inside the device, thereby adjusting the angle of the connecting rod 12 inside the device, thereby adjusting the angle of the right-side clamp 13 inside the device, making it convenient to clamp the limit ring 16 inside the clamp 13 and fix it, so that the limit ring 16 can be lifted.

[0044] The anti-slip ring 14 and the gripping clamp 13 are fixed to each other, and the centers of the circles of the anti-slip ring 14 and the cup body 15 coincide with each other. The anti-slip ring 14 and the gripping clamp 13 are fixed to each other. The anti-slip ring 14 can increase the friction between the cup body 15 and prevent the cup body 15 from sliding inside the device, causing the cup body 15 to fall from the inside of the device when the position is adjusted inside the device, and the limit ring 16 fixedly installed on the outside of the cup body 15 can limit the position of the cup body 15, thereby improving the stability of the cup body 15 during the translation process.

[0045] Example 3

[0046] like Figure 1-9 As shown, this embodiment is based on the previous embodiment, and differs from the previous embodiment in that this embodiment provides a rapid on-site detection device for the density of natural snow layers of great thickness, specifically.

[0047] The telescopic plate 20 forms a telescopic structure with the plate body 1 through the cooperation between the first hydraulic rod 19 and the mounting groove 18. The center lines of the telescopic plate 20 and the plate body 1 coincide with each other. During use, the first hydraulic rod 19 inside the plate body 1 is used to telescope and adjust the position of the telescopic plate 20 inside the device inside the mounting groove 18. The device moves to the position to be detected by moving the belt 4, and then extends the telescopic plate 20 through the first hydraulic rod 19 to adjust the position of the middle fixed plate 23 on the right side of the telescopic plate 20 inside the device. This can improve the flexibility of the device during use. When not in use, the telescopic plate 20 can also be folded to reduce the volume of the device and facilitate storage of the device.

[0048] Example 4

[0049] like Figure 1-9 As shown, this embodiment is based on the previous embodiment, and differs from the previous embodiment in that this embodiment provides a rapid on-site detection device for the density of natural snow layers of great thickness, specifically.

[0050] The middle fixed plate 23 forms a folding structure with the telescopic plate 20 through the cooperation between the second hydraulic rod 21 and the third rotating shaft 22. The triangular bottom plate 25 and the telescopic plate 20 are rotatably connected. The triangular bottom plate 25 has an arrow-shaped structure. The fixing sleeve rod 24 and the triangular bottom plate 25 are fixed to each other. The second hydraulic rod 21 adjusts the position of the middle fixed plate 23 on the right side inside the device by telescoping during use. Since the third rotating shaft 22 is installed on both sides of the second hydraulic rod 21, the middle fixed plate 23 will rotate inside the device through the third rotating shaft 22. At the same time, the triangular bottom plate 25 and the telescopic plate 20 are rotatably connected. Therefore, the triangular bottom plate 25 can be folded with the telescopic plate 20 inside the device through the second hydraulic rod 21, further reducing the volume of the device when stored and improving the flexibility of the device during use.

[0051] The third pulley 29 forms a transmission structure with the first pulley 27 through the drive belt 31, the second pulley 28 forms a transmission structure through the third pulley 29, and the fourth pulley 30 forms a transmission structure with the second pulley 28 through the drive belt 31. The second motor 26 drives the first pulley 27 to rotate inside the device, and then the first pulley 27 drives the third pulley 29 to rotate inside the device through the drive belt 31. Since the second pulley 28 and the third pulley 29 are coaxial and parallel to each other, the second pulley 28 will also rotate inside the device. Then the second pulley 28 drives the fourth pulley 30 to rotate inside the device through the drive belt 31, thereby driving the two sets of gear rods 35 above to rotate inside the device, so that the position of the sampling sleeve 33 inside the device can be adjusted through the top fixed plate 36 at the top.

[0052] The top fixing plate 36 and the sampling sleeve 33 are fixed to each other, and the top fixing plate 36 forms a lifting structure between the gear rod 35 and the triangular bottom plate 25. The top fixing plate 36 and the gear rod 35 are meshed with each other, and the sizes of the feeding rod 38 and the sampling sleeve 33 are consistent with each other. The feeding rod 38 forms a rotating structure through the third motor 37. During use, the fixed sleeve 24, the middle fixed plate 23 and the triangular bottom plate 25 are all fixed to each other, and the sampling sleeve 33 is sleeved inside the fixed sleeve 24 and can slide up and down. Therefore, when the gear rod 35 is driven to rotate, since the top of the gear rod 35 and the top fixing plate 36 are fixed to each other, and the top fixing plate 36 and the sampling sleeve 33 are fixed to each other, and the bottom of the gear rod 35 is installed on the triangular bottom plate 25, the gear rod 35 When rotating, it will drive the top fixed plate 36 to rise and fall inside the device to adjust the height of the sampling sleeve 33 inside the device. Then the third motor 37 drives the bottom feeding rod 38 to rotate inside the device. During detection, the sampling sleeve 33 is first installed at the position to be detected. Then the sampling sleeve 33 is driven downward to drill the snow. When the device descends to the height to be detected, the feeding rod 38 will export all the snow above the height to be tested through the snow outlet pipe 34. After complete export, the device continues to move downward one unit height, and then the feeding rod 38 will export all the snow inside the sampling sleeve 33. The snow obtained by the feeding rod 38 is snow per unit volume. At this time, the weight of the obtained snow is measured to obtain the density of snow at different levels.

[0053] The snow is taken out through the sampling sleeve 33, and then the fixed sleeve rod 24, the middle fixed plate 23 and the triangular bottom plate 25 are fixed to each other, and the sampling sleeve 33 is sleeved inside the fixed sleeve rod 24 and can slide up and down. Therefore, when the gear rod 35 is driven to rotate, the top of the gear rod 35 is fixed to the top fixed plate 36, and the top fixed plate 36 is fixed to the sampling sleeve 33. Then the bottom of the gear rod 35 is installed on the triangular bottom plate 25. Therefore, when the gear rod 35 rotates, it will drive the top fixed plate 36 to rise and fall inside the device, so as to adjust the height of the sampling sleeve 33 inside the device. The third motor 37 drives the feeding rod 38 at the bottom to rotate inside the device. During detection, the sampling sleeve 33 is first installed at the position to be detected, and then the sampling sleeve 33 is driven downward to drill the snow. When the device descends to the height to be detected, the feeding rod 38 will discharge all the snow above the height to be tested through the snow outlet pipe 34. After complete discharge, the device continues to move downward one unit height, and then the feeding rod 38 will discharge all the snow inside the sampling sleeve 33. The snow obtained by the feeding rod 38 is snow per unit volume. At this time, the density of snow at different levels can be obtained by measuring the weight of the obtained snow.

[0054] Working principle: First, the device moves to the position to be detected by moving the belt 4, and extends the telescopic plate 20 through the first hydraulic rod 19 to adjust the position of the middle fixed plate 23 on the right side of the telescopic plate 20 inside the device, which can improve the flexibility of the device during use. When not in use, the telescopic plate 20 can also be folded to reduce the volume of the device and facilitate storage of the device. Then the second hydraulic rod 21 telescopically adjusts the angle of the middle fixed plate 23 on the right side inside the device. Due to the rotation connection between the triangular bottom plate 25 and the telescopic plate 20, the middle fixed plate 23 is adjusted to be perpendicular to the telescopic plate 20. At this time, the second motor 26 drives the first pulley 27 to rotate inside the device, and then the first pulley 27 drives the third pulley through the driving belt 31. The pulley 29 rotates inside the device. Since the second pulley 28 and the third pulley 29 are coaxial and parallel to each other, the second pulley 28 will also rotate inside the device. Then the second pulley 28 drives the fourth pulley 30 to rotate inside the device through the driving belt 31, thereby driving the two sets of gear rods 35 above to rotate inside the device, so that the position of the sampling sleeve 33 inside the device can be adjusted through the top fixing plate 36 at the top. After that, the fixed sleeve 24, the middle fixing plate 23 and the triangular bottom plate 25 are all fixed to each other. At the same time, the sampling sleeve 33 is sleeved inside the fixed sleeve 24 and can slide up and down. Therefore, when the gear rod 35 is driven to rotate, since the top of the gear rod 35 is fixed to the top fixing plate 36, When the sampling sleeve 33 is inspected, the top fixing plate 36 and the sampling sleeve 33 are fixed to each other, and then the bottom of the gear rod 35 is installed on the triangular bottom plate 25. Therefore, when the gear rod 35 rotates, it will drive the top fixing plate 36 to rise and fall inside the device to adjust the height of the sampling sleeve 33 inside the device. Then the third motor 37 drives the bottom feeding rod 38 to rotate inside the device. When inspecting, the sampling sleeve 33 is first installed at the position to be inspected, and then the sampling sleeve 33 is driven downward to drill the snow. When the device descends to the height to be inspected, the feeding rod 38 guides all the snow above the height to be tested through the snow outlet pipe 34. After it is completely exported, the device continues to move downward by a unit height, and then the sampling sleeve 33 is taken out by the feeding rod 38. 3. All the snow inside is discharged. The snow obtained by the feeding rod 38 is snow per unit volume. At this time, the density of snow at different levels can be obtained by measuring the weight of the obtained snow. After the obtained snow is put into the cup body 15, the third hydraulic rod 39 drives the vertical tooth plate 9 to extend and retract inside the device. When the vertical tooth plate 9 extends and retracts, it can drive the meshing gears 10 on both sides to rotate inside the device. When rotating, the second rotating shaft 11 inside the device is also driven to rotate inside the device. Since the connecting rod 12 and the second rotating shaft 11 are fixed to each other, the connecting rod 12 will also rotate inside the device, thereby adjusting the angle of the connecting rod 12 inside the device, thereby adjusting the angle of the right gripper 13 inside the device.It is convenient to clamp the limiting ring 16 inside the gripping clamp 13 and fix it, so that the limiting ring 16 can be lifted. Then the first motor 5 drives the first rotating shaft 6 to rotate inside the device. Since the mounting plate 8 and the first rotating shaft 6 are fixed to each other, the mounting plate 8 will rotate inside the device through the first rotating shaft 6. During the rotation, the angle of the limiting ring 16 clamped inside the gripping clamp 13 on the right side of the mounting plate 8 inside the device can be adjusted, so that the snow discharged from the snow outlet pipe 34 can be adjusted to the top of the mass scale 2 for weighing, so that the density of the snow can be detected. At the same time, when the mounting plate 8 rotates, the balancing shaft 17 at the bottom slides inside the balancing chute 7 to improve the balance of the mounting plate 8 during the rotation process and improve the stability of the device. After rotating to the top of the mass scale 2, the cup body 15 is lowered. After lowering it, the weight of the snow is measured by the mass scale 2 to obtain the density of the snow.
