DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0033] A flood water level monitoring device in the present embodiment relates to the field of urban disaster reduction and prevention technology. By setting the device in the present application in low-lying areas of urban roads, underground projects, bridges, culverts, tunnels and other locations prone to waterlogging, the water level height at the relevant locations is monitored, and an alarm is issued in time to remind drainage personnel to come for drainage, so as to avoid accidents in which vehicles and people are flooded, causing unnecessary loss of life and property.

[0034] At the same time, the device in the present application can also be used in areas such as reservoirs, mines and wells to monitor the water level in relevant areas in real time, playing an important role in relevant safety fields such as disaster prevention and mitigation.

[0035] See also Figures 1 to 7 In this embodiment, a flood water level monitoring device includes: a cylinder 100, a core 200 and a float 300. The float 300 is arranged in the cylinder 100 and is slidably connected with the core 200. The external water enters the cylinder 100 from the bottom of the cylinder 100, and there is no need to open a hole in the cylinder 100, so it is convenient to dredge and maintain the cylinder 100. The water entering the cylinder 100 can lift the float 300 with the help of buoyancy. Based on the principle of communicating vessels, the water in the cylinder 100 and the water outside the cylinder 100 are set at the same height. The height of the float 300 can indirectly reflect the height of the water level. The change of the float 300 relative to the cylinder 100, the sensor 210 arranged on the core 200 can identify the height of the float 300 in real time and feedback to the relevant terminal, so as to issue an alarm in time and remind the drainage personnel to come for drainage.

[0036] In some embodiments, see Figure 1 and Figure 2A connecting unit 110 is provided at the bottom of the cylinder 100. The connecting unit 110 includes an intermediate piece 111, a gasket 112 and a connecting piece 113. The intermediate piece 111 is fixedly connected to the cylinder 100. The gasket 112 is made of a water-permeable material. External water penetrates into the cylinder 100 through the gap of the gasket 112, thereby achieving the connection between the water bodies inside and outside the cylinder 100 and keeping the liquid level flush. The monitoring device can be repaired by replacing the gasket 112, without the need for regular dredging, which saves trouble and effort.

[0037] The connecting piece 113 passes through the middle piece 111 and is fixedly connected to the ground, fixing the cylinder 100 on the ground. A filtering space is formed between the middle piece 111 and the ground. The gasket 112 is inserted into the filtering space. The gasket 112 is connected to the filtering space by an interference fit, which can facilitate the maintenance and replacement of the gasket 112.

[0038] The core 200 is arranged in the cylinder 100 and is coaxially arranged with the cylinder 100. A plurality of sensors 210 arranged along the length direction of the core 200 are arranged inside the core 200. Each sensor 210 can identify the floating body 300 individually, determine the height of the floating body 300, and thus determine the height of the accumulated water surface. The sensor 210 adjacent to the floating body 300 is triggered to obtain the height position of the floating body 300. Compared with the solution of setting a single infrared distance sensor 210 in the vertical direction to identify the height of the floating body 300, the present application can improve the fault tolerance of the device. If any single sensor 210 fails, it will not cause the water level recognition function in the present application to fail, and has higher reliability.

[0039] The float 300 is sleeved on the core body 200 and is slidably connected to the core body 200. The float 300 is spaced apart from the cylinder 100. When the float 300 slides relative to the core body 200, the cylinder 100 spaced apart relative to the float 300 cannot interfere with the movement of the float 300, thereby ensuring that the float 300 always floats above the water surface and accurately identifies the height of the water surface.

[0040] During the implementation process, the external water penetrates into the cylinder 100 from the gasket 112, the water surface in the cylinder 100 is consistent with the external liquid surface, the float 300 floats on the water surface and moves along the core 200, and the float 300 can trigger the sensor 210 located near the same height, thereby judging the water level. If necessary, an alarm is issued in time to remind the drainage personnel to come to dredge.

[0041] In some embodiments, see Figure 2The connection unit 110 further includes a bottom plate 114, which is located between the gasket 112 and the ground. The connecting member 113 passes through the bottom plate 114 and is fixedly connected to the ground. The bottom plate 114 and the connecting member 113 are slidably connected. The bottom plate 114 can move along the connecting member 113. The filtering space is formed between the bottom plate 114 and the middle member 111. The movement of the bottom plate 114 can expand or reduce the filtering space. A wedge 115 is provided between the bottom plate 114 and the ground. By controlling the insertion depth of the wedge 115, the wedge 115 can drive the bottom plate 114 to move, thereby pressing the gasket 112 located in the filtering space, and clamping and fixing the gasket 112.

[0042] In a further embodiment, an opening is provided in the middle of the bottom plate 114 , exposing the bottom of the gasket 112 , thereby expanding the contact area between the gasket 112 and the accumulated water, increasing the penetration speed of the accumulated water on the gasket 112 , and ensuring the synchronization of the liquid level height inside and outside the cylinder 100 .

[0043] In the specific implementation process, the middle piece 111 is specifically a flange ring, which is sleeved on the cylinder 100 and welded to the cylinder 100. The middle piece 111 can expand the contact area between the bottom of the cylinder 100 and the ground, and enhance the connection stability of the cylinder 100. The flange ring is provided with a hole, and the connecting piece 113 is inserted into the flange ring and fixed to the cylinder 100. Among them, there are at least two holes on the flange ring and they are equidistantly arranged around the flange, and the number of connecting pieces 113 corresponds to the number of holes. The connecting piece 113 is specifically an expansion bolt, which passes through the flange ring and the bottom plate 114 in turn to clamp the gasket 112 in the middle. The end of the expansion bolt is inserted into the ground and fixedly connected to the ground.

[0044] It should be noted that the gasket 112 is a fiber gasket 112, which is woven from a polymer material and has a certain thickness and flexibility. The polymer material can be plastic or resin. The gasket 112 can filter debris in the water to prevent the inner cavity of the cylinder 100 from being blocked.

[0045] See also Figure 3 and Figure 4 A packaging member 120 is provided above the cylinder, and the packaging member 120 is detachably connected to the cylinder 100. In the specific implementation process, at least two plugs are provided at the bottom of the packaging member 120, and sockets corresponding to the plugs are provided on the cylinder 100. The plugs can be inserted into the sockets, thereby realizing the detachable fixation of the two.

[0046] As another implementation, the packaging component 120 is connected to the cylinder 100 via bolts, and the packaging component 120 can be disassembled and assembled by disassembling and assembling the bolts, thereby achieving installation of the packaging component 120.

[0047] The package 120 is provided with a microprocessor and a transmitter, and the microprocessor and the transmitter are packaged in the package 120. The multiple sensors 210 are electrically connected to the microprocessor respectively. After the sensor 210 senses the float 300, it can transmit the signal to the microprocessor. After the microprocessor processes the signal, the water level information is obtained. The transmitter is electrically connected to the microprocessor, and the water level information is transmitted to a client terminal such as a mobile phone or a computer through the transmitter, which is convenient for relevant personnel to check.

[0048] Special note: Please refer to Figure 7 A connecting hole 130 is provided at the top of the cylinder 100. The connecting hole 130 can be connected to the outside world, so that the water level in the cylinder 100 is connected to the atmosphere. Through the connecting vessel principle, the water level in the cylinder 100 is consistent with the liquid level in the outside world. At the same time, the sensor 210 located in the core 200 is electrically connected to the microprocessor and the transmitter in the package 120 through the data line. The data line from the cylinder 100 passes through the connecting hole 130 and enters the package 120.

[0049] A pad 140 is also provided at the top of 100, and two ends of the pad 140 are respectively in contact with the cylinder 100 and the packaging member 120, and a gap connected to the connecting hole 130 is formed between the pads 140, which can prevent the packaging member 120 from blocking the connecting hole 130 and destroying the floating condition of the float 300.

[0050] In some embodiments, see Figure 3 and Figure 5 The core body 200 includes a core tube 220 and a support body 230. The bottom of the core tube 220 is sealed to prevent water from intruding. The bottom of the core tube 220 abuts against the gasket 112. The bottom of the core tube 220 is relatively fixed to ensure that the core tube 220 is always located at the central axis of the cylinder 100 and is not disturbed by external forces. The support body 230 is specifically strip-shaped and inserted into the core tube 220. The sensor 210 is connected to the support body 230.

[0051] The core body 200 is connected to the inner wall of the cylinder 100 through a bracket to fix the core body 200. The bracket is specifically annular, the inner circle of the bracket is connected to the core tube 220, and the outer circle of the bracket is connected to the inner wall of the cylinder 100. The bracket is relatively hollow, and the flood entering the cylinder 100 can be raised and lowered and moved in the cylinder 100 through the bracket.

[0052] It should be noted that: multiple sensors 210 are arranged at equal intervals, the distance between two adjacent sensors 210 is no more than 10 mm, and at least two sensors 210 simultaneously identify the floating body 300 and obtain the relative position height of the floating body 300. The resolution of the sensor 210 is within 10 mm, and a more accurate water level height value can be obtained. Compared with setting the infrared distance sensor 210 in the vertical direction, the accuracy of the present application is higher, and the measured value obtained is closer to the real value.

[0053] In the specific implementation process, a magnet is provided inside the float 300, and the sensor 210 adopts a magnetic sensor 210. The magnetic sensor 210 can determine the position of the float 300 by identifying the magnetic strength of the magnet, thereby obtaining the real-time water level height.

[0054] The floating body 300 is hollow inside and has a hole in the middle. The hole is connected to the outer wall of the floating body 300 to form a sealed space inside the floating body 300, so that the mass of the floating body 300 is reduced and floats on the water surface. The core tube 220 is inserted into the hole and slidably connected to the hole, and the floating body 300 can move freely relative to the core tube 220.

[0055] In some embodiments, see Figure 6 The bottom of the core tube 220 is provided with a boss 221, which is fixedly connected to the core tube 220, and the outer diameter of the boss 221 is larger than the inner diameter of the hole body. The boss 221 can prevent the floating body 300 from escaping from the core tube 220, thereby preventing the device from failing.

[0056] Workflow: stack the bottom plate 114, the gasket 112 and the middle piece 111 connected to the cylinder 100 on the ground in sequence, and bolts pass through the middle piece 111, the gasket 112 and the bottom plate 114 in sequence and are fixedly connected to the ground. When waterlogging occurs in the corresponding area, the water level in the installation area of ​​the cylinder 100 rises, and the accumulated water seeps into the cylinder 100 from the gasket 112. The float 300 floats on the water surface, and the accumulated water pushes the float 300 and moves along the core 200. The multiple sensors 210 located on the core 200 can identify the position of the float 300 in real time, thereby judging the water level.

[0057] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto.
