[0037] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0039] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0040] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side", "the other side", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present invention. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0041] In addition, terms such as "identical" do not require the components to be absolutely identical, but there can be slight differences. The term "vertical" merely means that the positional relationship between components is more vertical relative to "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0042] Please refer to Figure 1 、 Figure 2 , the present invention provides a technical solution: a hydrological flood mark monitoring device, including a chassis 1 installed on the ground through bolts or anchor rods. During installation, directly penetrate the bolts or anchor rods through the through holes on the chassis 1, and then drive the bolts or anchor rods into the ground.

[0043] A support seat 2 is fixed on the top of the chassis 1. The top of the support seat 2 is fixed with a measuring rod 3. The top of the measuring rod 3 is detachably connected with a lower shell 4 and an upper shell 5. The upper shell 5 is located on the top of the lower shell 4. A plurality of water inlet holes for flood water to flow in are opened on the outer wall of the support seat 2. The flood water will enter the inside of the measuring rod 3 through these water inlet holes, and the measuring rod 3 measures the highest water level of the flood water;

[0044] In this embodiment, the structure of the measuring rod 3 is as shown in Figure 3 、 Figure 4 、 Figure 5 . It includes a hollow rod c38 fixed to the top of the support seat 2. The top of the hollow rod c38 is fixed with a hollow rod a31. The top of the hollow rod a31 is fixed with a hollow rod b34. An annular support plate 6 is fixed to the outer wall of the bottom end of the hollow rod b34. The top of the annular support plate 6 is in contact with the bottom of the lower shell 4. A piston head 33 is inserted into the hollow rod a31. A piston rod 32 is fixed to the top of the piston head 33. A marker pen 36 for marking the highest water level of the flood is provided on the outer wall of the piston rod 32. When the flood water enters the inside of the hollow rod a31, it will push the piston head 33 and the piston rod 32 to move upward under the action of the buoyancy of the water body, so that the top end of the piston rod 32 passes through the through hole on the rotating seat 35 and moves into the upper shell 5. The provided upper shell 5 can protect the piston rod 32 from the outside to prevent it from getting damp. Since the marker pen 36 is in contact with the outer wall of the piston rod 32, during the upward movement of the piston rod 32 pushed by the flood water, the marker pen 36 will draw a vertical line on the outer wall of the piston rod 32, and the outer wall of the piston rod 32 is processed with scale lines. The values of the scale lines increase from top to bottom. The starting position marked as 0 is located at the top end of the outer wall of the piston rod 32. The scale corresponding to the bottom end of this vertical line is the highest water level of this flood, so as to realize the monitoring of the hydrological flood mark;

[0045] Moreover, the hollow rod a31 in the present invention is made of a transparent material, and the length of the hollow rod a31 is the same as the length of the scale line on the outer wall of the piston rod 32. The driving assembly 37 and the hollow rod c38 are both made of opaque materials. After the flood recedes, the piston rod 32 and the piston head 33 will move downward and reset. The hydrological staff can directly observe the vertical lines marked on the outer wall of the piston rod 32 through the hollow rod a31, and directly understand the highest water level of this flood by reading the scale value at the bottom of the vertical line, which is relatively convenient to operate.

[0046] To prevent the piston head 33 from falling into the support seat 2, as Figure 3 and Figure 4 shown, a support rod 7 is provided inside the support seat 2. The bottom end of the support rod 7 is fixed at the center of the top of the chassis 1, and the top end of the support rod 7 contacts the bottom of the piston head 33, so that the support rod 7 can support the piston head 33 from the bottom. The flood water entering the support seat 2 can enter the hollow rod a31 through the gap between the top end of the support rod 7 and the inner wall of the hollow rod c38.

[0047] Different from the transmission flood mark monitoring device, the present invention does not need to manually operate the device to reset after each flood recedes, and is more convenient to use. As Figure 4 shown: A rotatable rotating seat 35 is provided at the top of the marker pen 36. The rotating seat 35 is sleeved on the top end of the hollow rod b34 and rotates on the top end of the hollow rod b34. The marker pen 36 is fixed in the inner wall of the rotating seat 35 through a bracket. The rotating seat 35 is driven to rotate by the driving assembly 37. The rotating rotating seat 35 can drive the marker pen 36 to rotate on the outer wall of the piston rod 32, and can change the marking position after each flood recedes to mark the highest water level of multiple floods, and there is no need for manual operation, further improving the practicality;

[0048] Specifically, as Figures 6 - 10, the driving component 37 includes a worm gear 371 fixed to the outer wall of the rotating seat 35. One side of the worm gear 371 meshes with a worm 372. The worm 372 is movably connected to the inside of the upper shell 5 through a bearing. A turntable 373 is fixed to the rear end of the worm 372. There are two vertically distributed dial blocks 374 on one side of the turntable 373. The two dial blocks 374 are installed at the bottom end of the same bracket 375 through a rotating shaft 376. A threaded rod 378 is fixed to the top end of the bracket 375. A threaded hole 379 that is threadedly connected to the threaded rod 378 is opened at the top end of the piston rod 32. The threaded connection between the threaded rod 378 and the threaded hole 379 detachably connects the bracket 375 and the piston rod 32 together, and is used to synchronously drive the bracket 375 and the dial block 374 to move upward when the flood pushes the piston rod 32 upward. Moreover, the top end of the dial block 374 is processed into a smooth arc surface, which is used to contact the arc-shaped outer wall of the turntable 373 when the bracket 375 moves upward, so that the dial block 374 rotates downward under the restriction of the turntable 373 and does not rotate the turntable 373, as Figure 10 shown;

[0049] Since coil springs 377 are fixed to the rear ends of both rotating shafts 376, and the coil springs 377 are installed in the inner wall of the bracket 375, after the dial block 374 moves above the turntable 373, the rotating shaft 376 will drive the dial block 374 that rotates downward during the upward movement to reset to the position as shown in Figure 8 shown;

[0050] Moreover, two slots for accommodating the dial block 374 are processed at the bottom end of the bracket 375. Under the restriction of the slots, the dial block 374 is only allowed to rotate downward. Therefore, after the flood recedes, the dial block 374 moves downward synchronously with the piston rod 32. During the downward movement, one end of the dial block 374 will insert into the empty slot on the outer wall of the turntable 373. At the same time, under the restriction of the slot, the dial block 374 cannot rotate upward, so it will rotate the turntable 373, so that the rotating turntable 373 can drive the worm 372 and the dial block 374 to rotate, thereby realizing the drive of the rotating seat 35. Finally, the rotating seat 35 drives the marker pen 36 to move on the outer wall of the piston rod 32 to change the position of the marker pen 36 on the outer wall of the piston rod 32, so that the marker pen 36 can mark the highest water level of the flood again at a position adjacent to the previous vertical line when the next flood comes, without manual operation.

[0051] The present invention can be applied to the scenario of multiple floods. After marking the highest water levels of multiple floods, hydrological staff can see multiple vertical lines of different lengths on the outer wall of the piston rod 32. Each vertical line represents the highest water level of a flood. By observing the different bottom positions of the vertical lines, the difference in the highest water level of each flood can be intuitively understood, so as to help hydrological staff analyze the floods in this area.

[0052] In addition, after the marking material in the marker pen 36 is used up and the outer wall of the piston rod 32 is covered with vertical lines, it needs to be removed for replacement. Based on this, the bottom end of the upper shell 5 and the top end of the lower shell 4 of the present invention are fixed together by bolts. When disassembling, the bolts between the lower shell 4 and the upper shell 5 can be directly loosened, and then the upper shell 5 can be removed from the top end of the lower shell 4;

[0053] Then rotate the bracket 375 to screw the threaded rod 378 out of the threaded hole 379, remove the bracket 375, and then pull the rotating seat 35 out from the top of the hollow rod b34. Since the marking pen 36 and the rotating seat 35 are connected together, the marking pen 36 can be replaced after the rotating seat 35 is removed.

[0054] The outer wall of the hollow rod b34 is also processed with threads, and a threaded sleeve 8 is fixed at the top of the lower shell 4. By rotating the lower shell 4 upward, the lower shell 4 can be removed from the top of the hollow rod b34. Figure 5 As shown in the figure, the piston rod 32 is then pulled out from the inside of the hollow rod a31 from the top end of the hollow rod b34, and then the vertical lines marked on its surface are wiped off and it can be reused to reduce the cost of hydrological flood mark monitoring and enhance the practicality of the present invention.

[0055] It is worth noting that the present invention can be directly installed in areas where floods occur frequently. The entire device does not need to be driven by a power source. All structures except the marker pen 36 can be recycled and practical, which can reduce the cost of construction and monitoring and is more suitable for field flood mark monitoring.

[0056] A miniature camera for observing the vertical lines on the outer wall of the piston rod 32 can also be installed on the inner wall of the hollow rod a, and remote monitoring technology can be used to achieve the effect of remote reading. This can also save the cost of manual observation and recording after each flood recedes. The miniature camera and remote monitoring technology can be achieved through existing technical means and will not be further elaborated here.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
