Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an automatic measuring device and method for measuring the difference in seawater tides. Background Technology

[0002] During land reclamation construction, accurately grasping the changes in sea level during high and low tides is crucial for project progress. The difference in tidal range directly impacts project schedule planning, structural safety, and construction quality. Traditional sea level measurement relies primarily on manual, timed observations. In the complex and large-scale reclamation areas, manual measurement is extremely inefficient, requiring significant manpower and time. Furthermore, human factors such as visual errors by observers and inaccurate observation times severely affect the accuracy of measurement results, making it difficult to capture real-time and comprehensive dynamic information on sea level fluctuations. While existing automated measurement equipment offers some efficiency improvements, its complex structure requires specialized personnel for installation and commissioning, resulting in high costs. In harsh marine environments with high salinity and humidity, the equipment exhibits poor reliability and stability, frequently malfunctioning and severely disrupting normal engineering measurement work. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic measurement device and method for measuring the difference in seawater tides. The device is simple in structure, easy to install, low in cost, and can automatically measure the difference in seawater tides stably over a long period of time.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is an automatic measurement device for the difference in seawater tide height, comprising: A connecting plate is positioned horizontally directly above the sea surface to be tested, and multiple support legs are connected at intervals at the bottom of the connecting plate for support to the ground; A sliding rod is vertically and freely slidably connected to the connecting plate; A buoyancy ball, connected to the bottom of the slide bar, is used to automatically rise and fall with the ebb and flow of the tide, thereby driving the slide bar to slide up and down. A measuring component, connected to the top of the connecting plate, is used to record the height of a specified position on the slide bar at different times.

[0005] A further improvement of the automatic tidal range measuring device of the present invention is that the measuring components include: A positioning rod is located above the connecting plate, and one end of the positioning rod is vertically connected to the designated position of the slide rod; A limiting frame is vertically connected to the top of the connecting plate and located on one side of the slide rod, and the other end of the positioning rod is slidably inserted into the limiting frame; A scale is vertically connected to one side of the limiting frame. When the seawater is calm, the positioning rod points to the 0 mark of the scale. Two water level pointers are located above and below the positioning rod, respectively, with one end slidably connected to the limiting frame and the other end extending towards the scale. They are used to move as the positioning rod pushes. The static friction between each water level pointer and the limiting frame is greater than its own weight.

[0006] A further improvement of the automatic tidal difference measuring device of the present invention is that a sliding ring is provided below the connecting plate for the sliding rod to slide through, and a reinforcing rod is connected between each of the legs and the sliding ring.

[0007] A further improvement of the automatic tidal range measuring device of the present invention is that the length of each of the legs is adjustable and each of the legs is a telescopic rod.

[0008] A further improvement of the automatic measurement device for the difference in seawater tides of the present invention is that a level is connected to the top of the connecting plate to monitor whether the connecting plate is level.

[0009] An automatic method for measuring the difference in seawater tide levels includes the following steps: Step 1: Provide the above-mentioned automatic tidal range measurement device and install it at the location to be measured; Step 2: Use the measuring components to obtain the highest height of the slide bar at a specified position during high tide and the lowest height of the slide bar at a specified position during low tide, and calculate the difference in sea level between high and low tide at the location to be tested.

[0010] Compared with the prior art, the advantages of the present invention are: It has a simple structure, is easy to install, has low cost, and can automatically measure the difference in seawater tides stably over a long period of time. Attached Figure Description

[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] The automatic measurement device for the difference in seawater tides and its measurement method of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Please see Figures 1-4 As shown, the automatic tidal range measurement device includes: The connecting plate 1 is positioned horizontally directly above the sea surface to be tested. Multiple support legs 2 are connected at intervals at the bottom of the connecting plate 1 to support it to the ground. The slide bar 3 is vertically and freely slidably connected to the connecting plate 1; The buoyancy ball 4 is connected to the bottom of the slide bar 3 and is used to automatically rise and fall with the ebb and flow of the tide, so as to drive the slide bar 3 to slide up and down. The measuring component 5 is connected to the top of the connecting plate 1 and is used to record the height of the slider 3 at a specified position at different times.

[0020] Specifically, the connecting plate 1 has a through hole in the middle for the slide rod 3 to slide through.

[0021] Specifically, the length of the slide bar 3 is greater than the height of the connecting plate 1 from the ground.

[0022] By limiting the length of the slide bar 3, it is ensured that the slide bar is always slidably connected to the connecting plate 1 and does not fall off.

[0023] Specifically, the slide bar 3 is hollow inside.

[0024] By making the slide bar 3 a hollow structure, the weight of the slide bar 3 is reduced, ensuring that the slide bar 3 can slide up and down with the floating ball 4.

[0025] Specifically, lubricant is applied between the slide bar 3 and the connecting plate 1.

[0026] Applying this lubricant ensures the sliding stability of the slide bar 3.

[0027] Preferably, the measuring component 5 includes: Positioning rod 501 is located above the connecting plate 1, and one end of the positioning rod 501 is vertically connected to the designated position of the slide rod 3; The limiting frame 502 is vertically connected to the top of the connecting plate 1 and located on one side of the slide rod 3. The other end of the positioning rod 501 is slidably inserted into the limiting frame 502. The scale 504 is vertically connected to one side of the limiting frame 502. When the seawater is calm, the positioning rod 501 points to the 0 mark of the scale 504. Two water level pointers 503 are located above and below the positioning rod 501, respectively, with one end slidably connected to the limiting frame 502 and the other end extending to the scale 504, for moving with the push of the positioning rod 501. The static friction between each water level pointer 503 and the limiting frame 502 is greater than its own weight.

[0028] The process of measuring the difference in sea level during high and low tides: When the tide rises, the buoyancy ball 4 rises with the sea level and drives the sliding rod 3 to slide upwards, which in turn drives the positioning rod 501 to slide upwards along the limiting frame 502. The positioning rod 501 pushes the upper water level pointer 503 upwards, and the scale on the ruler 504 pointed to by the final position of the upper water level pointer 503 is the highest point of the high tide. When the tide falls, the buoyancy ball 4 falls with the sea level and drives the sliding rod 3 downwards, which in turn drives the positioning rod 501 to slide downwards along the limiting frame 502. The positioning rod 501 pushes the lower water level pointer 503 downwards, and the scale on the ruler 504 pointed to by the final position of the lower water level pointer 503 is the lowest point of the low tide. The difference in sea level during high and low tides can be calculated simply by using the above two sets of data.

[0029] By limiting the static friction between the water level pointer 503 and the limiting frame 502 to be greater than its own weight, the water level pointer 503 is prevented from sliding freely within the limiting frame 502 due to its own weight, ensuring that the water level pointer 503 can only move due to the push of the positioning rod 501, thus reducing errors.

[0030] Specifically, the top of the slide bar 3 extends upward to form an extension section, the diameter of which is smaller than that of the slide bar 3, and the positioning rod 501 is connected to the extension section.

[0031] By setting this extension section, the weight of the slide bar 3 is further reduced, ensuring that the slide bar 3 can slide up and down with the floating ball 4.

[0032] Preferably, a sliding ring 6 is provided below the connecting plate 1 for the sliding rod 3 to slide through, and a reinforcing rod 7 is connected between each leg 2 and the sliding ring 6.

[0033] By setting the sliding ring 6 in conjunction with the through hole on the connecting plate 1, the vertical sliding stability of the sliding rod 3 is ensured. In addition, the multiple reinforcing rods 7 are used to strengthen the support effect of the multiple support legs 2, thereby improving the overall structural stability.

[0034] Preferably, each of the outriggers 2 is adjustable in length and each of the outriggers 2 is a telescopic rod.

[0035] By setting the outrigger 2 as a telescopic rod, the length of the outrigger 2 can be adjusted to meet various working conditions.

[0036] Preferably, a level is connected to the top of the connecting plate 1 to monitor whether the connecting plate 1 is level.

[0037] Specifically, the level is a bubble level.

[0038] By setting up this bubble level, it is easy to determine whether the connecting plate 1 is level by observing whether the bubble of the bubble level is centered, so that the length of the support leg 2 can be adjusted in real time to adjust the levelness of the connecting plate 1.

[0039] An automatic method for measuring the difference in seawater tide levels includes the following steps: Step 1: Provide the above-mentioned automatic tidal range measurement device and install it at the location to be measured; Step 2: Using the five measuring devices, obtain the highest height of the slide bar 3 at the specified position during high tide and the lowest height of the slide bar 3 at the specified position during low tide, and calculate the difference in high and low tide at the location to be tested.
