[0031] The bottom of the supporting rod 20 is provided with a base 10 for connecting with the soil at the bottom of water, and the top of the supporting rod 20 is provided with a solar cell panel 60, a visual monitor 70 and an ultrasonic water level meter 80.

[0032] The sliding block 50 is slidingly sleeved on the supporting rod 20.

[0033] The monitoring box 110 is oppositely arranged on the sliding block 50 and is respectively provided with an alarm module 90 and a data transmission module 100; and a controller and a storage battery which are electrically connected with the solar cell panel 60, the visual monitor 70, the ultrasonic water level meter 80, the alarm module 90 and the data transmission module 100 are arranged in the monitoring box 110.

[0034] A floating plate 30 is arranged at the bottom of the monitoring box 110 for floating the sliding block 50 and the monitoring box 110 on the water surface.

[0035] The protection mechanism 40 comprises a protection plate 41 and a buffer assembly 42, the protection plate 41 is arranged around the outside of the monitoring box 110; one end of the protection mechanism 40 is connected with the protection plate 41, and the other end is movably connected with the monitoring box 110.

[0036] Through the above technical solution, the depth measuring device can be stably fixed on the soil at the bottom of water through the base 10; the sliding block 50 is floated on the water surface under the action of the floating plate 30, and the water level data is obtained through the ultrasonic water level meter 80 and the surrounding water surface environment is obtained through the visual monitor 70; by arranging the protection mechanism 40, the supporting rod 20, the sliding block 50 and the monitoring box 110 can be separated from the outside to avoid the impact of floating objects on the water surface; the above-mentioned protection plate 41 has good impact resistance and is not easy to be deformed or damaged after being impacted; at the same time, by arranging the buffer assembly 42, when the protection plate 41 is impacted, the buffer effect can be played, the protection performance of the protection plate 41 is further ensured, the accuracy of water level monitoring is effectively ensured, and the service life of the depth measuring device is improved.

[0037] The solar panel 60 is used to convert light energy into electrical energy and store in the battery; the battery can power the visual monitor 70, the ultrasonic water level meter 80, the alarm module 90 and the data transmission module 100; the ultrasonic water level meter 80 calculates the water level height by emitting and receiving ultrasonic signals and using the propagation speed of sound waves in the air and the time difference; the visual monitor 70 is used to detect the water surface environment around the depth measuring device and transmit to the terminal device through the data transmission module 100; the alarm module 90 is used to send an alarm signal when the water level exceeds the set range. The above-mentioned solar panel 60, visual monitor 70, ultrasonic water level meter 80, alarm module 90 and data transmission module 100 are common devices in the prior art, which can be selected and used according to the needs, and the specific structure is not described here. In this application, the alarm module 90 and the data transmission module 100 are arranged at the top of the two monitoring boxes 110; the controller and the battery are arranged inside the monitoring box 110.

[0038] The above-mentioned sliding block 50 has a through hole with two open ends, which is sleeved outside the support rod 20 and can slide along the support rod 20; its size and cross-sectional shape can be set according to the needs, in this embodiment, the cross-sectional shape of the sliding block 50 is designed as a square, and is symmetrically arranged relative to the through hole; the monitoring box 110 is arranged on the outer side of the sliding block 50 to ensure that the sliding block 50 is balanced.

[0039] The above-mentioned floating plate 30 can form a sufficient buoyancy on the water surface to drive the monitoring box 110 and the sliding block 50 to slide freely along the support rod 20 with the water surface, so that the monitoring box 110 is always located above the water surface, thereby ensuring the normal operation of the solar panel 60, the visual monitor 70, the ultrasonic water level meter 80, the alarm module 90, the data transmission module 100, the controller and the battery. The specific shape of the above-mentioned floating plate 30 can be square, circular or other shapes, which can be a whole or multiple independent individuals; in the embodiment of the application, the monitoring box 110 is a rectangular structure, and the floating plate 30 is consistent with the shape and size of the bottom surface of the monitoring box.

[0040] Further, in the embodiment of the application, as shown in Figure 1 , Figure 2As shown, the protective plate 41 comprises two V-shaped side plates connected, and the connecting tips of the side plates are directed outward; two protective plates 41 are oppositely arranged, and the two sides thereof are connected by a plurality of isolation ropes 43. The side plates have sufficient height and size to cover the entire height range of the monitoring box 110; the connecting tips of the side plates are directed outward and are located outside the end surface of the monitoring box 110 away from the sliding block 50, so that the end surface and the two side plates form an internal space with a certain size, and the buffer assembly 42 is arranged in the internal space; the internal space is not too large, otherwise the weight of the overall device will be affected; nor is it too small to affect the buffering effect of the buffer assembly 42; the included angle between the two side plates can be set according to the needs, and in use, the two protective plates 41 are arranged along the water flow direction, and the V-shaped connection design can better guide the water surface floating objects to the two sides of the side plates; the outer surface of the side plate is a flat plate, and when the water surface floating objects hit the outer surface of the side plate, they can move along the outer surface, thereby moving away from the depth gauge; the isolation ropes 43 are arranged along the height of the side plate, which on the one hand forms a closed protection mechanism with the protective plate 41 to fully isolate the water surface floating objects; on the other hand, when the protective plate 41 is impacted and the buffer assembly 42 is deformed, the arrangement of the isolation ropes 43 allows the protective plate 41 to move with it and restore to its original state after the buffering is completed, achieving good buffering effect.

[0041] Compared with the prior art, the protective plate 41 in the present application is not easily damaged, reduces the maintenance cost, and improves the service life of the device.

[0042] Further, in the embodiment of the present application, as shown in Figure 2 The buffer assembly 42 comprises a sliding rod 421 and an elastic member 422, one end of the sliding rod 421 is connected to the inner side of the corner of the protective plate 41, and the other end is slidingly connected with the monitoring box 110; the elastic member 422 is arranged between the sliding rod 421 and the sliding block 50. When the protective plate 41 is impacted, the protective plate 41 drives the sliding rod 421 to move towards the monitoring box 110 and compresses the elastic member 422, and the elastic member 422 deforms to absorb the impact energy, and then slowly releases to drive the protective plate 421 to reset; this design can reduce the instantaneous impact force peak of the impact on the protective plate 41, thereby effectively protecting the protective plate 41 from deformation or damage due to stress; by arranging the sliding rod 421 on the inner side of the corner of the protective plate 41, the protective plate 41 can effectively transmit the impact force to the sliding rod 421 when subjected to horizontal, vertical and oblique impact, and the impact force is dissipated under the joint action of the sliding rod 421 and the elastic member 422, thereby improving the adaptability of the protective plate 41 to multi-directional impact. In addition, this arrangement also ensures the stability of the device and the accuracy of the water level measurement.

[0043] Further, in the embodiment of the present application, the monitoring box 110 is provided with a sliding groove for accommodating the sliding rod 421, and the elastic member 422 is arranged in the sliding groove. Preferably, the sliding groove is arranged in the interior of the monitoring box 110 and avoids the battery and the controller; the sliding groove has two open ends, one of which is open towards the protective plate 41, and the other of which is communicated with the sliding block 50; the elastic member 422 is arranged in the sliding groove and located between the sliding rod 421 and the sliding block 50, and when the sliding rod 421 slides along the sliding groove towards the sliding block 50, the elastic member 422 is compressed and deformed; when the elastic member 422 is released, the sliding rod 421 is pushed to slide along the sliding groove towards the protective plate 41, so as to realize the buffering of the impact force.

[0044] In the above embodiment, in order to ensure that the sliding rod 421 is always located in the sliding groove during the sliding process and does not come out of the sliding groove to cause the protective mechanism 40 to be separated from the monitoring box 110, the sliding groove is further provided with a limiting member, so that the sliding rod 421 does not come out of the sliding groove when sliding towards the protective plate 41; or one end of the elastic member 422 is connected to the sliding block 50, and the other end is connected to the sliding rod 421, which can pull the sliding rod 421 tight during the resetting process, so as to realize the limiting of the sliding rod 421.

[0045] Further, in a preferred embodiment, the buffering assembly 42 further comprises a damping member 423, and the elastic member 422 is sleeved outside the damping member 423; one end of the damping member 423 is fixed to the sliding block 50, and the other end is connected to the sliding rod 421. The above damping member 423 is used for controlling the direction of the elastic member 422 during single deformation, can be elongated or shortened when subjected to an external force, and can make the two ends of the damping member 423 move away from or close to each other, so as to avoid the repeated stretching and deforming of the elastic member 422 and the repeated movement of the protective plate 41, and also can play a role in assisting the guiding and limiting of the sliding rod 421 when sliding along the first annular groove, so as to effectively improve the stability of the buffering assembly 42, thereby ensuring the buffering effect of the buffering assembly 42 in long-term use. The damping member 423 can adopt the existing technology of a telescopic damper or other structures capable of playing a damping role, which is not limited here.

[0046] Further, the support rod 20 comprises a measuring rod 21 and a fixed rod 22 threadedly connected to the top end of the measuring rod 21; the measuring rod 21 is provided with scale marks; the base 10 is fixed to the bottom end of the measuring rod 21; the solar panel 60 is arranged at the top end of the fixed rod 22; one side of the fixed rod 22 is provided with a connecting frame 23, and the visual monitor 70 and the ultrasonic water level meter 80 are arranged on the connecting frame 23. The sliding block 50 can move within the length range of the measuring rod 21, and the water level data can be manually read by reading the scale marks corresponding to the sliding block 50, so as to correct the accuracy of the ultrasonic water level meter 80; by arranging the fixed rod 22, the solar panel 60 can be replaced and repaired as needed, which is more convenient and fast; the connecting frame 23 is perpendicular to the fixed rod 22 and extends to one side, which provides a basis for the installation of the visual monitor 70 and the ultrasonic water level meter 80, and also enables the ultrasonic water level meter 80 to be aligned with the water surface outside the protection mechanism 40, thereby ensuring the accuracy of the obtained water level data.

[0047] Further, in order to enable the sliding block 50 to slide along the measuring rod 21 more smoothly, the inner wall of the sliding block 50 is embedded with a plurality of rolling balls 51, and the rolling balls 51 are in rolling connection with the measuring rod 21, so as to reduce the friction between the sliding block 50 and the measuring rod 21, and ensure that the sliding block 50 can slide along the measuring rod 21 under the buoyancy of the floating plate 30, thereby floating on the water surface and avoiding that the monitoring box 110 cannot be normally used due to the interference of the water body.

[0048] Further, the bottom of the base 10 is threadedly connected with a fixed cone 11 foot, and it can be understood that the fixed cone 11 foot has a set length, and the bottom end thereof is pointed, so as to be conveniently inserted into the soil body, thereby stably fixing the base 10 and the support rod 20 at the set position.
