[0022] like Figure 1 to Figure 11 As shown, the tidal level observation device provided by the embodiment of the present invention includes: A vertical pipe 1 is hollow inside and vertically immersed in the water body. A cylindrical float 2 that rises or falls with the water level is placed inside the vertical pipe 1. The diameter of the cylindrical float 2 is adapted to the inner diameter of the vertical pipe 1. An annular baffle cover 101 is also provided at the bottom end of the vertical pipe 1. The diameter of the cylindrical float 2 is larger than the inner diameter of the annular baffle cover 101. A through hole 102 for the entry and exit of liquid or gas is provided on the wall of the vertical pipe 1. The cylindrical float 2 is made of non-absorbent plastic.

[0023] A rangefinder assembly 3 is arranged at the inner upper end of the vertical pipe 1, and the rangefinder assembly 3 includes a rangefinder 311 and an adjustment assembly for adjusting the rangefinder 311 forward, backward, leftward and rightward, so that the optical axis of the light beam emitted by the rangefinder 311 is parallel to the longitudinal axis of the vertical pipe 1; a mounting device is fixedly connected to the wall of the vertical pipe 1 to fix the vertical pipe 1 on a structure near the water or on the bottom of the water.

[0024] In the above embodiment, when specifically set, the material of the cylindrical float 2 is preferably non-absorbent plastic, such as polyetheretherketone PEEK, polyphenylene sulfide PPS, etc. These materials have very low water absorption and can maintain stable size and performance in a humid environment. If the length of the vertical pipe 1 is not long enough, two or more vertical pipes 1 can be connected by a vertical pipe connector 10, and only an annular baffle cover 101 is set at the bottom end of the lowest vertical pipe 1. The inner diameter of the annular baffle cover 101 is smaller than the diameter of the cylindrical float 2, so it can be ensured that the cylindrical float 2 will not fall out from the bottom of the vertical pipe 1. A through hole 102 for liquid or gas to enter and exit is set on the wall of the vertical pipe 1 to ensure that the atmospheric pressure inside the vertical pipe 1 is consistent with the outside. The embodiment of the present invention directly places the cylindrical float 2 in the internal space of the vertical tube 1. Since the diameter of the cylindrical float 2 is adapted to the inner diameter of the vertical tube 1, the cylindrical float 2 can float up and down freely in the vertical tube 1 without the problem of the float getting stuck or being blocked by organisms attached to the seawater. The adjustment component can adjust the rangefinder 311 forward, backward, left and right, so that the optical axis of the light beam emitted by the rangefinder 311 is parallel to the longitudinal axis of the vertical tube 1, thereby improving the measurement accuracy of the rangefinder 311.

[0025] It should be noted that when making the fixing device of the rangefinder 311, due to the influence of various factors, the central light beam emitted by the rangefinder 311 may not be parallel to the longitudinal axis of the vertical tube 1. If the deviation is large, it is easy to cause the light beam emitted by the rangefinder 311 to be unable to be reflected back to the receiving end of the rangefinder 311 after irradiating the float on the water surface, thereby causing measurement errors or making it impossible to measure. Therefore, an adjustment component is provided in this embodiment.

[0026] In one specific embodiment, the tidal level observation device is as follows: Figure 3~Figure 4 As shown, the adjustment component includes: The disc fixing seat is fixedly connected to the pipe wall of the upper end of the vertical pipe 1; wherein the disc fixing seat comprises: A disc fixing plate 301 is horizontally arranged, and its diameter is larger than the outer diameter of the vertical tube 1; a ring-shaped fixing plate 302 is fixed below the disc fixing plate 301, and the outer diameter of the ring-shaped fixing plate 302 is matched with the inner diameter of the vertical tube 1. A mounting hole 310 is arranged on the annular wall of the ring-shaped fixing plate 302, and the mounting hole 310 is a screw hole. After the ring-shaped fixing plate 302 is inserted into the upper end of the vertical tube 1, a fourth screw is tightened into the mounting hole 310 to fix the ring-shaped fixing plate 302 on the tube wall of the vertical tube 1; The first bracket 303 is arranged on the bottom surface of the disc fixing plate 301, and the first bracket 303 includes two first side panels that are relatively and vertically arranged; the first bracket 303 also includes a square frame that is fixedly connected to the upper ends of the two first side panels and is horizontally arranged, and the square frame is fixed on the bottom surface of the disc fixing plate 301 and is located inside the circular fixing plate 302.

[0027] The second bracket 304 includes two second side plates that are opposite and vertically arranged, a third side plate that is vertically arranged between the two second side plates, and a fourth side plate that is horizontally arranged between the two second side plates. The second bracket 304 is arranged between the two first side plates of the first bracket 303, and the rangefinder 311 is arranged in a space surrounded by the two second side plates, the third side plate, and the fourth side plate. The first side plate and the second side plate on the same side are fixedly connected in a relatively rotatable manner, and the specific setting method is: a first circular hole and a first arc-shaped long hole 315 arranged directly below the first circular hole are arranged on both of the first side plates, the first rotation axis screw 307 passes through the circular hole and is screwed to the second side plate, and the first screw 308 passes through the first arc-shaped long hole 315 and is screwed to the second side plate; when the first screws 308 on both sides are loosened, the two second side plates rotate around the first rotation axis screws 307, and the two first screws 308 move in their corresponding first arc-shaped long holes 315 respectively, then the second bracket 304 rotates forward or backward relative to the first bracket 303, and after the correction is completed, the first screws 308 on both sides are tightened; The rangefinder 311 is fixedly arranged on the third side plate in a manner of being rotatable relative to the third side plate, and is specifically arranged as follows: a second circular hole and a second arc-shaped long hole 312 arranged directly below the second circular hole are arranged on the third side plate, a second rotation axis screw 305 passes through the second circular hole and is screwed to the rangefinder 311, and a second screw 306 passes through the second arc-shaped long hole 312 and is screwed to the rangefinder 311; when the second screw 306 is loosened, the rangefinder 311 is rotated around the second rotation axis screw 305, and the second screw 306 moves in the second arc-shaped long hole 312, then the rangefinder 311 rotates leftward or rightward relative to the third side plate, and after calibration is completed, the second screw 306 is tightened again, and then the rangefinder 311 is fixed to the bottom surface of the fourth side plate for further fixation.

[0028] In the above embodiment, the adjustment assembly provided in the present invention can not only stably fix the rangefinder 311 on the internal upper end of the vertical tube 1, but also enable the second bracket 304 to rotate forward or backward relative to the first bracket 303, thereby adjusting the front-to-back direction of the optical axis of the light beam emitted by the rangefinder 311, and can also enable the rangefinder 311 to rotate leftward or rightward relative to the third side plate of the second bracket 304, thereby adjusting the left-right direction of the optical axis of the light beam emitted by the rangefinder 311. Therefore, overall, the parallelism between the optical axis of the light beam emitted by the rangefinder 311 and the longitudinal axis of the vertical tube 1 can be adjusted, thereby improving the accuracy and precision of the data measured by the rangefinder 311. In specific implementation, for the second bracket 304, the left side of the third side plate is fixedly connected to the side of the second side plate arranged on the left, and the right side is fixedly connected to the side of the second side plate arranged on the right. For the square frame, it is fixed to the bottom surface of the disc fixing plate 301 by four second screws 309.

[0029] In one specific embodiment, the tidal level observation device is as follows: Fig.11 As shown, it also includes a control device box 5, which is electrically connected to the rangefinder 311, and the rangefinder 311 transmits the collected tide data to the control device box 5; the device control box 5 includes: a micro control unit MCU501, a mobile communication module 502 and a Beidou receiver 503, the Beidou receiver 503 is connected to the Beidou satellite 505 for communication, the Beidou satellite 505 is connected to the Beidou receiver 506 for communication, and then transmitted to the server via the Internet, the mobile communication module 502 is connected to the mobile communication base station system 507 for communication, the mobile communication module 502 and the Beidou receiver 503 are both connected to the micro control unit 501, and the tide data is transmitted to the server 504 via the mobile communication module 502 or the Beidou receiver 503.

[0030] In the above specific implementation, in order to transmit the collected water level data to the server in real time, both a mobile communication module 502 and a Beidou receiver 503 are provided, and Beidou short message transmission signals are adopted. The mobile communication module 502 has a large amount of data sent and low communication costs, but the disadvantage is that data cannot be transmitted in areas where mobile communication signals are not covered, such as islands far away from the mainland; the Beidou short message transmission mode does not require mobile communication signals and can solve the data transmission in the offshore area, but its disadvantage is that the amount of data sent is small and the communication costs are high. This embodiment combines these two transmission modes. When the mobile communication signal is available, the mobile signal is preferentially used for data transmission. When the mobile communication signal is unstable or in areas where the mobile signal cannot be covered, such as isolated islands far away from the mainland, the Beidou short message mode is adopted for transmission. The two transmission modes can be automatically judged and switched by the micro control unit MCU to achieve data transmission without dead ends.

[0031] It should be noted that, since the mobile communication module 502 and the Beidou receiver 503 are arranged in the control device box in this embodiment, in order not to affect the use of the Beidou receiver and the mobile communication antenna, the control device box is made of non-metallic materials. If the control device box is made of metal materials, the mobile communication module 502 and the Beidou receiver 503 should be arranged outside the control device box.

[0037] In one specific embodiment, the tidal level observation device is as follows: Fig.10 As shown, the installation device includes: An underwater base 430, on which the bottom end of the vertical pipe 1 is fixed; An L-shaped fixing frame 431, on which the control device box 5 is fixed a vertical rod; The fourth clamp is arranged on the horizontal rod body of the L-shaped fixing frame and is tightly connected to the upper end of the vertical pipe 1.

[0038] In the above embodiment, the structure of the installation device is suitable for use in the case where there is no building to rely on near the water. A stable underwater base 430 is installed under the water, and the vertical pipe 1 together with the control device box 5 is erected on the underwater base 430. The control device box 5 is placed above the water surface to ensure that it is not submerged in the water at any time. This installation method requires that the vertical pipe 1 itself has great strength, because in addition to being a limiter for the float, the vertical pipe 1 also bears the function of supporting other control device boxes. It is recommended to be made of steel pipe.

[0039] The above three installation devices with different structures are suitable for different outdoor environments. Since various different environments will be encountered in actual application scenarios, there are corresponding different installation methods and installation structures. If there are no regular artificial structures on the coastline of the area, it is necessary to install a fixed underwater base under the water. Obviously, this installation method is more troublesome and requires a large investment. However, if there are buildings such as docks, piers, breakwaters, etc. on the coastline, a leaning installation can be adopted. Therefore, this embodiment is provided with a variety of installation structures to facilitate adaptation to different scenarios.

[0040] In one specific embodiment, the tide level observation device further includes a third clamp 8, which is arranged in the middle or lower part of the vertical pipe 1; wherein the number of the third clamps 8 is greater than or equal to 1, and each of the third clamps 8 is fixedly connected to one end of a support rod 9, and the other end of the support rod 9 is hinged to the wall of the structure.

[0041] In the above embodiment, if the vertical pipe 1 is long, it is necessary to add a supporting component on the wall of the dock facing the water, so as to hinge the other end of the supporting rod 9 to the wall of the structure to ensure the stability of the vertical pipe 1.

[0042] The number of devices and processing scales described here are used to simplify the description of the present invention. Applications, modifications and variations of the present invention will be obvious to those skilled in the art.

[0043] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
