Technical Field

[0001] This utility model relates to the technical field of settlement observation instruments, specifically to a seawall settlement observation instrument that prevents slippage. Background Technology

[0002] Seawalls, also known as steep-wall sea dikes, are man-made structures built along the coast using boulders or stone blocks to form steep walls, used to block tides and prevent waves. Reference to Publication No. CN111979971A, Publication Date: 2020-11-24, which discloses a type of seawall structure, also provides this information. Seawalls are an important barrier along the southeastern coast of China. Because tides can cause significant damage to coastal areas, settlement monitoring of seawalls is necessary to prevent excessive tidal damage.

[0003] However, most of the seawall settlement monitoring instruments currently on the market, such as the one disclosed in the public announcement (No. CN205537607U, date of public announcement: 2016-08-31), is an automatic settlement monitoring instrument.

[0004] There are still some shortcomings in its use, such as:

[0005] 1. After installation, it is easily affected by the impact of sea waves and may slip, which may lead to inaccurate measurements, and it is difficult to provide warnings after it deviates;

[0006] 2. It is inconvenient to observe the subsidence offset of the seawall intuitively. Utility Model Content

[0007] The purpose of this invention is to provide a seawall settlement monitoring instrument that prevents slippage. This solves the problems of seawall settlement monitoring instruments being easily slipped due to wave impact after installation, leading to inaccurate measurements, difficulty in providing warnings after deflection, and inconvenience in visually observing seawall settlement offset.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a seawall settlement observation instrument to prevent slippage, comprising a mounting rod and a plurality of sinkers symmetrically arranged about the center of the mounting rod, wherein a steel cable is provided between the sinkers and a fixing block fixedly installed on the mounting rod;

[0009] It also includes a fixing component that is sleeved around the periphery of the mounting rod and keeps it centrally arranged, which includes a pressure sensor. The pressure sensor corresponds to a plurality of protrusions arranged in a circumferential array on the outer wall of the mounting rod and maintains a predetermined distance between the protrusions.

[0010] The end of the mounting rod that extends out of the water surface is equipped with a camera.

[0011] Preferably, it also includes a concrete base set on the seabed and an L-shaped fixing seat;

[0012] The fixing base includes a horizontal part and a vertical part. The horizontal part is located on the top of the concrete base, while the main body of the seawall is arranged on the adjacent surfaces of the horizontal and vertical parts.

[0013] Preferably, the fixing assembly includes a frustum-shaped mounting cylinder and a protective cylinder disposed on the narrow opening section of the mounting cylinder, while the pressure sensor is mounted on the inner wall of the mounting cylinder.

[0014] The mounting cylinder is located within the horizontal section and the concrete base, and the protective cylinder extends from the horizontal section into the seawater;

[0015] The piercing part of the mounting rod is inserted into the seabed through the wide opening of the mounting cylinder.

[0016] Preferably, the driven nail is disposed in the horizontal section and within the concrete base.

[0017] Preferably, a connecting ring is fixedly provided on the end face of the exposed horizontal portion of the sinker, and the connecting ring is provided with a connecting hook for connecting the steel cable to it.

[0018] Preferably, a connecting block is welded to the end of the mounting rod, and a protective assembly consisting of a tempered glass plate snapped onto the connecting block is fixedly mounted on the connecting block, while the camera is assembled inside the housing.

[0019] Preferably, the camera's acquisition surface faces the tempered glass plate, and the tempered glass plate is provided with scale lines.

[0020] In the above technical solution, the seawall settlement observation instrument provided by this utility model to prevent slippage has the following beneficial effects:

[0021] 1. It is equipped with a sinker, an installation rod and a steel cable. The installation rod is fixed by being driven into the seabed through the fixing component, and the sinker is fixed by being driven into the concrete base through the fixing seat. Since the steel cable is connected to the connecting ring through the connecting hook, the steel cable is connected to the connecting ring through the connecting hook, thereby further limiting the installation rod and improving the installation stability of the installation rod.

[0022] 2. It is equipped with a pressure sensor, a protrusion, and a fixing component. The pressure sensor is fixedly connected to the inner surface of the mounting cylinder, and the pressure sensor is connected to an external signal transmitting device through a wire. At the same time, the pressure sensor and the protrusion are distributed at equal angles about the vertical center line of the mounting rod. When the mounting rod is tilted or slipped due to the impact of waves, the protrusion hits the pressure sensor, and then sends out a warning signal through the signal transmitting device, which facilitates warning and improves practicality.

[0023] 3. It is equipped with protective components, a camera and a mounting rod. A tempered glass plate is fixedly connected to the left end face of the shell, and the outer surface of the tempered glass plate is set with scale values. When the camera is observing, the settlement value of the main body of the seawall can be conveniently and intuitively displayed through the scale values ​​on the outer surface of the tempered glass plate.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-4 As shown, a seawall settlement monitoring instrument to prevent slippage includes a mounting rod 4 and a plurality of sinkers 12 arranged symmetrically about the center of the mounting rod 4. A steel cable 9 is provided between the sinkers 12 and the fixing block 8 fixedly installed on the mounting rod 4.

[0032] It also includes a fixing component 13 that is sleeved around the mounting rod 4 and keeps it centered. It includes a pressure sensor 14, which corresponds to a plurality of protrusions 15 arranged in a circular array on the outer wall of the mounting rod 4 and maintains a predetermined distance between the protrusions 15.

[0033] The end of the mounting rod 4 that extends out of the water is equipped with a camera 7.

[0034] Specifically, in this embodiment, before installing the seawall settlement monitoring instrument, it is necessary to determine the bedrock using GPS geological exploration equipment. This bedrock refers to rock that is independent of the main body 3 of the seawall to be monitored and will not move synchronously with the settlement of the main body 3 of the seawall. After determining the installation location, holes are pre-drilled in the bedrock and steel bars are inserted. Finally, a concrete base 1 is formed by pouring concrete, and then the fixing seat 2 of the precast concrete component is installed. Figure 1 Install as shown.

[0035] Furthermore, the fixing component 13 in the embodiment includes a frustum-shaped mounting cylinder 1302 and a protective cylinder 1301 disposed on the narrow section of the mounting cylinder 1302. Before pouring the concrete base 1, the mounting cylinder 1302 is pre-positioned in the square groove, centered, and then the concrete is poured. When installing the fixing seat 2, the protective cylinder 1301 passes through a pre-drilled hole in the horizontal section, with the inner wall of the hole contacting half of the outer wall of the mounting cylinder 1302. Figure 1 As shown.

[0036] After completing the above steps, multiple sinkers 12 are arranged in a circular array with the protective cylinder 1301 as the center, passing through the horizontal section and being inserted into the concrete base 1. Then, the aforementioned installation rod 1 is passed through the protective cylinder 1301 and then inserted into the seabed.

[0037] It should be noted that the mounting rod 4 is located on the axis of the protective cylinder 1301, while the pressure sensor 14 is mounted on the inner wall of the mounting cylinder 1302. Therefore, when the mounting rod 4 is deflected or slipped due to the impact of waves, the protrusion 15 will hit the pressure sensor 14. The pressure sensor 14 is connected to an external signal transmitter through a wire, and then the signal transmitter will send a warning signal to remind the staff to repair the seawall settlement monitoring instrument that is designed to prevent slippage.

[0038] The electronic components and control programs in the above embodiments are common technical knowledge to those skilled in the art. The power supply required for operation can be provided by photovoltaic panels and batteries or directly by 220V mains power, which will not be described in detail.

[0039] Furthermore, in this embodiment, a connecting ring 11 is fixedly installed on the end face of the exposed horizontal portion of the sinker 12. The connecting ring 11 and the steel cable 9 are connected by a connecting hook 10, thereby pulling the mounting rod 4 to maintain a vertical state and further limiting the mounting rod 4.

[0040] Furthermore, a connecting block 5 is welded to the end of the mounting rod 4, and a protective assembly 6 consisting of a tempered glass plate 602 snapped onto the port of the housing 601 is fixedly mounted on the connecting block 5. The camera 7 is assembled inside the housing 601. The acquisition surface of the camera 7 faces the tempered glass plate 602, and the tempered glass plate 602 is provided with scale lines. When the camera 7 observes, it can conveniently and intuitively display the settlement value of the seawall body 3 through the scale values ​​set on the outer surface of the tempered glass plate 602 on the housing 601.

[0041] Working principle:

[0042] After the installation of the seawall settlement monitoring instrument is completed, the camera 7 is activated to observe the scale reading through the tempered glass plate 602, obtaining the current water level of the main body of the seawall 3. By continuously recording the scale reading of this water level gauge under different hydrological conditions such as flood season and dry season, and comparing and analyzing the relative changes of the water level reading at the same location over time (excluding the influence of short-term fluctuations such as tides and waves), it is possible to help determine whether the main body of the seawall 3 has settled and its settlement trend.

[0043] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
