[0031] As shown in Figures 1 to 3 , in one embodiment, the snow hardness measuring device comprises a support plate 100, a guide column 200 and a probe rod 300. The bottom surface of the support plate 100 is used to abut against the ground, and the support plate 100 is provided with a clearance hole (not marked in the figure). The guide column 200 is arranged on the top surface of the support plate 100 and is provided with a guide rail 210 extending in the direction perpendicular to the top surface of the support plate 100. The probe rod 300 is in sliding connection with the guide rail 210, and the probe rod 300 passes through the clearance hole in the sliding direction relative to the guide rail 210, and the probe rod 300 is provided with a pressure sensor 310 for detecting the resistance received by the probe rod 300 during sliding.

[0032] As shown in Figures 1 to 3 , specifically, the support plate 100 is a square plate, and in the use process, one of the two plate surfaces with the largest area of the support plate 100, that is, the bottom surface, abuts against the ground, and the other surface, that is, the top surface of the support plate 100. The clearance hole penetrates the support plate 100 along the distribution direction of the top surface and the bottom surface of the support plate 100. The guide column 200 extends upward from the top surface of the support plate 100 in the direction perpendicular to the top surface of the support plate 100, so that the guide rail 210 extending in the direction perpendicular to the top surface of the support plate 100 can be arranged. The area of the top surface of the support plate 100 is greater than the area of the contact part of the guide column 200. The probe rod 300 can slide along the guide rail 210, that is, it can move in the direction perpendicular to the top surface of the support plate 100, and the probe rod 300 can pass through the support plate 100 through the clearance hole during movement.

[0033] Referring to Figures 1 to 3 As shown, in the use of the snow hardness measuring device, the support plate 100 abuts against the ground, thereby stably supporting the measuring device on the ground. Then, by moving the probe rod 300 downward along the guide rail 210, the probe rod 300 can pass through the support plate 100 via the avoiding hole and then be inserted into the ground below the support plate 100. As the probe rod 300 continues to move downward along the guide rail 210, the probe rod 300 can continuously penetrate into the snow, and meanwhile, the probe rod 300 can obtain the resistance received in the process of penetrating into the snow through the detection value of the pressure sensor 310, so as to analyze the hardness of the snow at different depths according to the resistance.

[0034] In the scheme of the present embodiment, the guide column 200 is arranged on the top surface of the support plate 100, the guide rail 210 is arranged on the guide column 200, and the probe rod 300 is slidingly connected with the guide rail 210. The support plate 100 can abut against the snow ground to be measured, thereby stably supporting the measuring device on the ground. Then, by moving the probe rod 300 downward along the guide rail 210, the probe rod 300 can pass through the support plate 100 via the avoiding hole and then be inserted into the snow ground below the support plate 100. As the probe rod 300 continues to move downward along the guide rail 210, the probe rod 300 can continuously penetrate into the snow, and meanwhile, the probe rod 300 can obtain the resistance received in the process of penetrating into the snow through the detection value of the pressure sensor 310, so as to analyze the hardness of the snow at different depths according to the resistance. Therefore, the snow hardness measuring device of the present scheme can penetrate into the snow to a certain depth by moving the probe rod 300 along the guide rail 210, thereby measuring the hardness of the snow below a certain depth of the snow ground, so that the snow hardness information is more comprehensive, which is helpful for better analyzing the snow condition. Moreover, the support plate 100 can stably support the measuring device, avoiding the inclination and tilting of the measuring device.

[0035] As shown, Figures 1 to 4 The snow hardness measuring device further comprises a driving mechanism, which is in transmission connection with the probe rod 300 to drive the probe rod 300 to slide relative to the guide rail 210. The driving mechanism comprises a sliding block 410, a lead screw 420 and a motor 430. The sliding block 410 is slidingly connected with the guide rail 210 and fixedly connected with the probe rod 300. The lead screw 420 is in threaded connection with the sliding block 410. The motor 430 is in transmission connection with the lead screw 420 to drive the lead screw 420 to rotate, thereby driving the sliding block 410 to slide along the guide rail 210.

[0036] Referring to Figures 1 to 4As shown, specifically, guide rail 210 consists of two parallel tracks. The width of slider 410 is greater than the distance between the two tracks, allowing it to slide smoothly with the two tracks of guide rail 210. Lead screw 420 has threads on its surface and is positioned between the two tracks of guide rail 210, extending in the same direction as guide rail 210. Slider 410 is threadedly connected to lead screw 420. The shaft of motor 430 is connected to lead screw 420, enabling the activated motor 430 to drive lead screw 420 to rotate. This rotation, via the threaded connection between lead screw 420 and slider 410, causes slider 410 to move along guide rail 210, subsequently moving probe rod 300 along the extension direction of guide rail 210. Simultaneously, by controlling the forward and reverse rotation of motor 430, the upward or downward movement of slider 410 can be controlled.

[0037] Those skilled in the art will understand that by setting a drive mechanism to drive the probe rod 300 to slide relative to the guide rail 210, measurement becomes more convenient. Furthermore, by using a motor 430 to drive the lead screw 420 to rotate, which in turn drives the slider 410, which is threadedly connected to the lead screw 420, to slide along the guide rail 210, thereby causing the probe rod 300 to move along the extension direction of the guide rail 210, this driving method is more stable and has higher accuracy.

[0038] It should be noted that in some other embodiments, the drive structure may also be a linear motor. Alternatively, no drive structure may be provided, and power may be supplied manually, for example, by manually driving a lead screw with a rocker arm.

[0039] like Figures 1 to 3 As shown, in one embodiment, the snow hardness measuring device further includes a pressure plate 500, which is disposed at the top of the guide post 200 and fixedly connected to the guide post 200. The probe rod 300 is movable to a position located between the pressure plate 500 and the support plate 100. Specifically, the pressure plate 500 and the support plate 100 are the same size and shape. The pressure plate 500 is disposed at the top of the guide post 200, thereby clamping the guide post 200 between it and the support plate 100. The probe rod 300 is also movable to a position located between the pressure plate 500 and the support plate 100.

[0040] As can be understood by those skilled in the art, the pressing plate 500 and the support plate 100 are arranged at two ends of the guide column 200 respectively in a way that the plate surfaces are opposite to each other, so as to clamp the guide column 200 together, and the probe rod 300 can also move to a position between the pressing plate 500 and the support plate 100. On the one hand, the pressing plate 500 and the support plate 100 can protect the guide column 200 and the probe rod 300 during transportation or use of the measuring device, so as to reduce the possibility of collision of the guide column 200 and the probe rod 300. On the other hand, the pressing plate 500 can be pressed during use, so as to make the measuring device more stable. In addition, the pressing plate 500 also helps to provide a pressing position, so as to facilitate the carrying of the measuring device.

[0041] As shown in Figures 1 to 3 , the snow hardness measuring device further comprises a plurality of reinforcing rods 600 arranged between the bottom surface of the pressing plate 500 and the top surface of the support plate 100 and fixedly connected with the bottom surface of the pressing plate 500 and the top surface of the support plate 100 respectively. By arranging the reinforcing rods 600, the stability of the overall structure of the measuring device is improved, so that the overall structure is more stable.

[0042] As shown in Figures 1 to 3 , the pressing plate 500 is provided with a mounting hole (not labeled in the figure), and the motor 430 is arranged on the top of the pressing plate 500, so as to be connected with the lead screw 420 through the mounting hole and fixed in the mounting hole. Specifically, the motor 430 is located on the side of the pressing plate 500 away from the support plate 100, and is in transmission connection with the lead screw 420 through the mounting hole. In other words, the motor 430 is not located between the pressing plate 500 and the support plate 100.

[0043] By arranging the motor 430 on the top of the pressing plate 500, the user can easily observe the motor 430, so as to discover the failure of the motor 430 in time. At the same time, the motor 430 is convenient for maintenance.

[0044] As shown in Figures 1 to 3 , the driving mechanism further comprises a speed reducer 440 arranged between the motor 430 and the lead screw 420. The speed reducer 440 plays a role of increasing torque, which helps to reduce the cost of the motor 430.

[0045] As shown in Figures 1 to 2 , the edges of the pressing plate 500 and the support plate 100 are surrounded by a protective ring 700 made of elastic material. For example, the protective ring 700 can be made of rubber, elastic plastic or the like. The protective ring 700 helps to reduce the impact force on the pressing plate 500 or the support plate 100 when the measuring device is tilted, so as to avoid excessive shock of the measuring device, thereby helping to protect the measuring device.

[0046] AsFigures 1 to 3 As shown, the snow hardness measuring device further comprises a limiting block 800 fixed to the guide column 200 and provided with a limiting hole (not labeled in the figure) with a hole diameter matched with the outer diameter of the probe rod 300, and the probe rod 300 passes through the limiting hole. Specifically, the limiting block 800 is fixed to a position close to the bottom end of the guide column 200 and located on the moving path of the probe rod 300. At the same time, the limiting block 800 is provided with a limiting hole for the probe rod 300 to pass through. The limiting block 800 can limit the probe rod 300 through the limiting hole, so that the movement of the probe rod 300 is more stable, and the probe rod 300 is also protected to a certain extent.

[0047] Although not shown in the figure, the bottom surface of the support plate is provided with a sawtooth-shaped protrusion, so that the support plate can be more firmly supported on the snow ground.

[0048] At this point, those skilled in the art should recognize that although the present application has been shown and described in detail in the above embodiments, many other variations or modifications can be directly determined or deduced according to the disclosure of the present application without departing from the spirit and scope of the present application, which conform to the principles of the present application. Therefore, the scope of the present application should be understood and recognized as covering all these other variations or modifications.
