Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping of water areas such as rivers, lakes, and seas. More specifically, the present invention relates to a tidal level observation device. Background Art

[0002] Water level observation is often required for mapping and hydrological surveys of rivers, lakes, and oceans, as well as for safety monitoring of upstream water bodies. This allows for tide level corrections through depth measurements, determination of mean sea level, calculation of depth datums, and water level monitoring of rivers and lakes. Current methods for tide level observation include manual observation, well-type self-recording tide gauges, pressure tide gauges, radar tide gauges, laser tide gauges, ultrasonic tide gauges, and rangefinder-float tide gauges. Patent CN212567593U discloses a water level monitoring device using a rangefinder and float-type tide gauge. Specifically, the device comprises a measuring tube with a water inlet at its bottom and a receiving chamber connected to the inlet. The inner walls of the receiving chamber are provided with a pair of vertical tracks. A float is slidably connected to the vertical tracks at its left and right ends. The float is a floating plate with receiving grooves at its left and right ends. These grooves contain balls that match the vertical tracks. A measuring unit, mounted on the measuring tube and used to indicate the float's position, includes an infrared ranging sensor located at the top of the receiving chamber and electrically connected to a PLC controller. The measuring tube is mounted on a base plate with a through hole corresponding to the water inlet and an anchor rod with protruding spikes. In this patent, the float is mounted on the vertical tracks with ball bearings and the infrared ranging sensor is used for position measurement, avoiding measurement errors caused by the float becoming stuck. However, the track and ball bearings described in the aforementioned patents are complex, requiring high precision and high implementation costs. Furthermore, due to their small size, the track is easily blocked by upturned silt or marine growth (such as shells), causing it to become stuck and fail. Furthermore, if the beam from the distance meter strikes the pipe wall, it can easily cause measurement errors or even prevent measurement, making it difficult to apply in practice.

[0057] like Figures 1 to 11 As shown, the tide level observation device provided by the embodiment of the present invention includes:

[0058] A vertical pipe 1 is hollow inside and vertically immersed in the water body. A cylindrical float 2 is placed inside the vertical pipe 1, which rises or falls with the water level. 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 material of the cylindrical float 2 is non-absorbent plastic.

[0059] A rangefinder assembly 3 is disposed at the upper end of the vertical tube 1. The rangefinder assembly 3 includes a rangefinder 311 and an adjustment assembly for adjusting 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; and a mounting device is fixedly connected to the wall of the vertical tube 1 to secure the vertical tube 1 to a structure near water or to the bottom of the water.

[0060] In the above embodiment, when specifically set up, the material of the cylindrical float 2 is preferably a non-water-absorbing 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 an annular baffle cover 101 is only provided 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 that the cylindrical float 2 can be prevented from falling out of the bottom of the vertical pipe 1. A through hole 102 for the entry and exit of liquid or gas is provided on the wall of the vertical pipe 1 to ensure that the atmospheric pressure inside the vertical pipe 1 is consistent with that of the outside world. In this embodiment of the present invention, a cylindrical float 2 is directly placed within the interior space of the vertical tube 1. Because the diameter of the cylindrical float 2 is adapted to the inner diameter of the vertical tube 1, the cylindrical float 2 can freely float up and down within the vertical tube 1, eliminating the risk of the float becoming stuck or clogged by organisms in the seawater. An adjustment assembly is provided to adjust the rangefinder 311 forward, backward, left, and right, ensuring 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.

[0061] It should be noted that when manufacturing 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 hit the float on the water surface and not be reflected back to the receiving end of the rangefinder 311, thereby causing measurement errors or even the inability to perform measurement. Therefore, this embodiment provides an adjustment component.

[0062] In one embodiment, the tide level observation device is as follows: Figure 3~Figure 4 As shown, the adjustment component includes:

[0063] A disc fixing seat is fixedly connected to the upper end of the vertical pipe 1; wherein the disc fixing seat includes:

[0064] A circular fixing plate 301 is arranged horizontally and has a diameter larger than the outer diameter of the vertical tube 1. A circular fixing plate 302 is fixed below the circular fixing plate 301. The outer diameter of the circular fixing plate 302 is adapted to the inner diameter of the vertical tube 1. A mounting hole 310 is provided on the annular wall of the circular fixing plate 302. The mounting hole 310 is a screw hole. After the circular 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 circular fixing plate 302 to the wall of the vertical tube 1.

[0065] 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 opposite and vertically arranged; the first bracket 303 also includes a square frame that is fixedly connected to the upper end heads 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.

[0066] The second bracket 304 includes two second side panels that are opposite and vertically arranged, a third side panel that is vertically arranged between the two second side panels, and a fourth side panel that is horizontally arranged between the two second side panels. The second bracket 304 is arranged between the two first side panels of the first bracket 303, and the rangefinder 311 is arranged in the space enclosed by the two second side panels, the third side panel, and the fourth side panel.

[0067] The first side panel and the second side panel on the same side are fixedly connected in a relatively rotatable manner. The specific setting method is as follows: a first circular hole and a first arc-shaped long hole 315 located directly below the first circular hole are provided on both first side panels; a first rotation axis screw 307 passes through the circular hole and is screwed to the second side panel, and a first screw 308 passes through the first arc-shaped long hole 315 and is screwed to the second side panel; when the first screws 308 on both sides are loosened, the two second side panels 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, so that the second bracket 304 rotates forward or backward relative to the first bracket 303. After the correction is completed, the first screws 308 on both sides are tightened;

[0068] The rangefinder 311 is fixedly mounted on the third side panel in a manner rotatable relative to the third side panel. Specifically, the third side panel is provided with a second circular hole and a second arc-shaped elongated hole 312 directly below the second circular hole. A second rotation axis screw 305 passes through the second circular hole and is screwed to the rangefinder 311. A second screw 306 passes through the second arc-shaped elongated hole 312 and is screwed to the rangefinder 311. When the second screw 306 is loosened, the rangefinder 311 rotates about the second rotation axis screw 305. The second screw 306 moves in the second arc-shaped elongated hole 312, causing the rangefinder 311 to rotate leftward or rightward relative to the third side panel. After calibration is completed, the second screw 306 is tightened again, and the rangefinder 311 is further fixed to the bottom surface of the fourth side panel.

[0069] In the above-described embodiment, the adjustment assembly provided by the present invention not only stably secures the rangefinder 311 to the inner upper end of the vertical tube 1, but also allows 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. It also allows the rangefinder 311 to rotate left or right relative to the third side plate of the second bracket 304, thereby adjusting the left-to-right direction of the optical axis of the light beam emitted by the rangefinder 311. Therefore, overall, the parallelism of the optical axis of the light beam emitted by the rangefinder 311 with 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. Specifically, for the second bracket 304, the left side of the third side plate is fixedly connected to the side of the second side plate on the left, and the right side is fixedly connected to the side of the second side plate on the right. The square frame is secured to the bottom surface of the disc fixing plate 301 via four second screws 309.

[0070] In one embodiment, the tide level observation device is as follows: Figure 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.

[0071] In the above-described specific embodiment, to transmit collected water level data to a server in real time, both a mobile communication module 502 and a Beidou receiver 503 are provided, using Beidou short message transmission signals. Mobile communication module 502 transmits a large amount of data and offers low communication costs, but suffers from the inability to transmit data in areas not covered by mobile communication signals, such as islands far from the mainland. Beidou short message transmission, which does not require mobile communication signals, can address data transmission in offshore areas. However, its drawbacks are the smaller amount of data transmitted and the higher communication costs. This embodiment combines these two transmission modes. When a mobile communication signal is available, the mobile signal is prioritized for data transmission. When the mobile communication signal is unstable or in areas not covered by mobile signals, such as islands far from the mainland, Beidou short message transmission is used. The microcontroller unit (MCU) automatically determines and switches between these two transmission modes, achieving seamless data transmission.

[0072] It should be noted that, in this embodiment, the mobile communication module 502 and the Beidou receiver 503 are disposed within the control device box. Therefore, to avoid interfering with the use of the Beidou receiver and the mobile communication antenna, the control device box is constructed of non-metallic materials. If the control device box were constructed of metal, the mobile communication module 502 and the Beidou receiver 503 would need to be disposed outside the control device box.

[0073] In one embodiment, the tide level observation device, such as 5~ Figure 7 As shown, the mounting device includes:

[0074] A first clamp 7 is fastened to the upper end of the vertical pipe 1. The first clamp 7 includes a clamp ring 420 and two fixing plates 419 provided at both ends of the clamp ring 420. Each fixing plate 419 is provided with two arc-shaped holes 423, and the four arc-shaped holes 423 are all located on the same circumference.

[0075] The connecting plate includes a first thick connecting plate 417 and a second thin connecting plate 418 fixedly connected to the first thick connecting plate 417. Four third screws 421 pass through the four arc-shaped holes 423 to fix the first clamp 7 to the second thin connecting plate 418. When the four third screws 421 are loosened, the first clamp 7 is adjusted to rotate left or right so that it is vertical in the left-right direction, thereby correcting the verticality of the vertical pipe 1 in the left-right direction.

[0076] A fixed frame is fixed to a structure near the water; specifically, the fixed frame includes: a horizontal frame 416, on which a plurality of beam limiting rings 412 are provided along the front-to-back direction, and the first beam 410 is disposed in the plurality of beam limiting rings 412;

[0077] There are two vertical frames 411, which are respectively arranged at the front end and the rear end of the horizontal frame 416, and are clamped on the opposite side walls of the structure. The vertical frame 411 includes: a pair of symmetrically arranged vertical rods 4111, a pair of inverted triangle support frames 4110 arranged on the outside of the pair of vertical rods 4111, and a horizontal rod 4112 connecting the pair of vertical rods 4111 and the pair of inverted triangle support frames 4110; wherein, each vertical rod of the pair of vertical rods 4111 is provided with a plurality of fixing components for adjustment, and the fixing components include: a first screw rod 415 horizontally arranged through the vertical rod, a support plate 413 is provided on the inner end of the first screw rod 415, and an adjustment dial 414 is provided on the outer end, and the adjustment dial 414 is rotated to make the support plate 413 close to the wall of the structure.

[0078] A first crossbeam 410 is disposed above the fixed frame in a manner movable in the front-to-back direction. The first crossbeam 410 is fixedly connected to the connecting plate. The first crossbeam 410 is adjusted to move forward or backward so that the vertical pipe 1 is vertical in the front-to-back direction.

[0079] A rod 6 is vertically arranged on the fixed frame, and the control device box 5 is fixed on the rod 6 .

[0080] In the above embodiment, the structure of the installation device is suitable for use in situations where there are wall-like structures near the water, such as the low wall on top of a vertical breakwater, or the wheel guard at the front of the dock. This installation method does not require embedding the screw 415 on the building, is easy to install and disassemble, and is also easy to carry and reuse, saving costs. The provided installation device includes a first clamp 7, a connecting plate, a fixed frame and a first crossbeam 410. The connection method of the first clamp 7 and the connecting plate can facilitate fine-tuning the verticality of the vertical pipe 1 in the left and right directions; the connection method of the first crossbeam 410 and the fixed frame can facilitate adjustment of the verticality of the vertical pipe 1 in the front and back directions, thereby ensuring that the vertical pipe 1 is in a vertical state, which can further increase the accuracy and precision of the measurement of the rangefinder 311. In a specific implementation, preferably, two fixing members for adjustment are provided on each vertical rod of a pair of vertical rods 4111. The fixing members include: a first screw rod 415, a support plate 413 provided on the inner end of the first screw rod 415, and an adjustment dial 414 provided on the outer end. The support plate 413 can make the fixed frame close to the wall. Rotating the adjustment dial 414 can adjust the tightness between the fixed frame and the wall. The eight fixing members can be used to adjust the closeness between the fixed frame and the wall, which is both stable and easy to install and disassemble. In addition, specifically, on the horizontal frame 416, four to five beam limiting rings 412 are provided along the front-to-back direction. The beam limiting rings 412 are adapted to the diameter of the first beam 410 to prevent the first beam 410 from moving in other directions.

[0081] In one embodiment, the tide level observation device is as follows: Figures 8 and 9 As shown, the mounting device includes:

[0082] Main columns 424 are vertically arranged and fixed on the top surface of the structure 429;

[0086] In the above-described embodiment, the structure of the installation device is suitable for use in situations where structures such as docks exist on the coastline, significantly reducing costs. In specific configurations, the arrangement of the two second clamps 427 and the other ends of the two second crossbeams 426 can also be adopted. The second clamps 427 can also include a clamp and two fixing plates disposed at the ends of the clamps. Each fixing plate is provided with two arcuate holes, and the four arcuate holes are located on the same circumference. The four arcuate holes are fixed to the other end of the second crossbeam 426 to adjust the verticality of the vertical pipe 1. In specific implementation, the main column 424 is fixed to the top surface of the structure as follows: a support plate 428 is provided at the bottom end of the main column 424. The support plate 428 has a screw hole at each of its four corners. During installation, a screw is inserted into a hard surface (such as a concrete dock surface), inserted into the support plate 428, and then tightened with screws.

[0087] In one embodiment, the tide level observation device is as follows: Figure 10 As shown, the mounting device includes:

[0088] An underwater base 430, on which the bottom end of the vertical pipe 1 is fixed;

[0089] L-shaped fixing frame 431, the control device box 5 is fixed on the vertical rod of the L-shaped fixing frame;

[0090] The fourth clamp is provided on the horizontal rod of the L-shaped fixing frame and is fastened to the upper end of the vertical pipe 1 .

[0091] In the above-described embodiment, the mounting structure is suitable for use near water without any structures to support it. A stable underwater base 430 is installed underwater, and the riser pipe 1, along 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 does not submerge at any time. This installation method requires the riser pipe 1 to be extremely strong. In addition to serving as a float limiter, the riser pipe 1 also supports the other control device boxes. Therefore, it is recommended to be made of steel pipe.

[0092] The three different installation structures are suitable for different outdoor environments. In actual application scenarios, different environments are encountered, so there are different installation methods and installation structures accordingly. If the coastline in the area does not have any regular artificial structures, 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 provides a variety of installation structures to facilitate adaptation to different scenarios.

[0093] 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.

[0094] In the above embodiment, if the vertical pipe 1 is long, it is necessary to add a supporting component on the wall facing the water of the dock so as to hinge the other end of the support rod 9 to the wall of the structure to ensure the stability of the vertical pipe 1.
