Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, and in particular to a groundwater level monitoring device near a channel lining. Background Technology

[0002] In water conservancy projects such as agricultural irrigation, urban water supply, and water resource allocation, canals serve as crucial water conveyance facilities, and their stability and safety are paramount. Canal lining is a key measure to protect the canal structure and reduce water seepage losses; however, excessive lining can obstruct groundwater circulation, causing changes in the groundwater level and consequently affecting the surrounding ecological environment and canal safety. Therefore, monitoring the groundwater level near canal lining is of great significance for assessing the effectiveness of lining, preventing soil erosion caused by seepage, and ensuring the safe operation of the canal.

[0003] Currently, traditional groundwater level monitoring methods are often limited to single-point or limited-location measurements, making it difficult to comprehensively reflect the spatial distribution and dynamic changes of groundwater levels near the lining, resulting in inaccurate and incomplete monitoring data. To address this, we propose a multi-point groundwater level monitoring device near channel linings, which can effectively improve the accuracy of groundwater level monitoring data. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a groundwater level monitoring device near channel linings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A groundwater level monitoring device near a channel lining includes a support and a monitoring component. The bottom inner wall of the support is provided with a winding mechanism, and one end of the winding mechanism is provided with a protective cylinder. The monitoring component is located inside the channel.

[0007] The inner circumferential wall of the protective cylinder is provided with a channel; the monitoring component includes a top support fixedly connected to the inner wall of the top of the channel, a partition plate fixedly connected to the extension end of the top support, two support rods symmetrically hinged to the bottom surface of the partition plate, and two or more water level sensors fixedly connected to one side of the support rods at equal intervals. The partition plate and the channel form an up-and-down sliding fit.

[0008] As a further improvement of this utility model: the outer circumference of the protective cylinder is symmetrically provided with openings, and an elastic body is fixedly connected to the top inner wall of the opening.

[0009] As a further embodiment of this utility model: the winding mechanism consists of a motor fixedly connected to the inner wall of the bottom of the support and a wire roller rotatably connected to one side of the support. The output end of the motor is connected to one end of the wire roller through a coupling. A measuring rope is wound around the outer circumference of the wire roller, and the top of the protective cylinder is located at one end of the measuring rope.

[0010] As a further improvement of this utility model: a solar panel is fixedly connected to the top outer wall of the bracket, and a power source is fixedly connected to the inner wall of one side of the bracket.

[0011] As a further improvement of this utility model, a positioner is fixedly connected to the bottom inner wall of the bracket.

[0012] As a further improvement of this utility model, a warning light is fixedly connected to the top surface of the bracket.

[0013] As a further improvement of this utility model, a display screen is fixedly connected to one side of the bracket.

[0014] As a further improvement of this utility model, positioning pins are inserted into the four perimeters of the bracket.

[0015] Compared with the prior art, this utility model provides a groundwater level monitoring device near channel lining, which has the following beneficial effects:

[0016] 1. The groundwater level monitoring device near the channel lining, through the installation of monitoring components and other structures, can synchronously and effectively monitor the changes in groundwater level at different locations in the same area near the channel lining, thereby improving the accuracy of groundwater level monitoring data and being easy to use.

[0017] 2. The groundwater level monitoring device near the channel lining is activated when the protective cylinder is lowered to the appropriate position by the measuring rope. The lower top partition plate moves down, and the bottom ends of the two support rods extend out along the opening until the bottom surface of the partition plate is in contact with the bottom inner wall of the channel. At this time, the two support rods also extend to a horizontal position under the support of the elastic body above them, thus completing the spatial distribution of multiple water level sensors on the support rods, which is convenient to operate.

[0018] 3. The groundwater level monitoring device near the lining of the channel uses multiple water level sensors to transmit real-time groundwater level information to the control module, which can then remotely send the information to the back-end for staff to understand, and to the display screen to show the water level at different spatial points in the area.

[0026] Example 1

[0027] A groundwater level monitoring device near the canal lining, such as Figure 1-4 As shown, the device includes a support 1 and a monitoring component. Positioning pins 101 for fixing the device to the ground near the channel lining are inserted at the four periphery positions of the support 1. According to the monitoring requirements, the device is fixed in position near the channel lining by the positioning pins 101.

[0028] Furthermore, the bottom inner wall of the bracket 1 is provided with a winding mechanism for connecting the monitoring component and adjusting its lifting height. The winding mechanism consists of a motor 3 fixed to the bottom inner wall of the bracket 1 by bolts and a wire roller 301 rotatably connected to one side of the bracket 1. The output end of the motor 3 is connected to one end of the wire roller 301 through a coupling. A measuring rope is wound around the outer circumference of the wire roller 301. One end of the measuring rope passes through the bottom surface of the bracket 1 and is tied to a protective cylinder 2. Starting the motor 3 can accurately control the protective cylinder 2, especially the lowering height of the monitoring component inside it, via the measuring rope.

[0029] The inner circumferential wall of the protective cylinder 2 is provided with a channel 201, and the monitoring component is installed inside the channel 201.

[0030] In order to effectively monitor the changes in groundwater level at different locations in the same area near the channel lining, the monitoring component includes a top support 11 fixed to the inner wall of the top of the channel 201 by bolts and electrically connected to the control module, a partition plate 9 fixed to the extension end of the top support 11 by bolts, two support rods 10 symmetrically hinged to the bottom surface of the partition plate 9, and multiple water level sensors 13 equidistantly fixed to one side of the support rods 10 by bolts and communicatively connected to the control module. The top support 11 can be an electric telescopic rod, etc., and the partition plate 9 and the channel 201 form an up-and-down sliding fit.

[0031] Preferably, the outer circumferential wall of the protective cylinder 2 is symmetrically provided with openings 202 for one end of the support rod 10 to extend out. An elastic body 12 is fixedly connected to the top inner wall of the opening 202. The elastic body 12 can be rubber or the like. When the protective cylinder 2 is lowered to a suitable position by the measuring rope, the control top support 11 is activated, the lower top partition plate 9 moves down, and then supports the bottom ends of the two support rods 10 to extend out along the opening 202 until the bottom surface of the partition plate 9 is in contact with the bottom inner wall of the channel 201. At this time, the two support rods 10 also extend to a horizontal position under the support of the elastic body 12 above them, thereby completing the spatial distribution of multiple water level sensors 13 on the support rods 10, which is convenient to operate.

[0032] Furthermore, a display screen 8 electrically connected to the control module is fixed to one side of the bracket 1 by bolts; multiple water level sensors 13 transmit the real-time monitored groundwater level information to the control module so that it can be remotely sent to the backend for staff to understand, and sent to the display screen 8 to display the water level of groundwater at different spatial points in the area.

[0033] Working Principle: Based on monitoring requirements, the equipment is positioned near the channel lining using positioning pins 101. The starter motor 3 lowers the protective cylinder 2 to the target underground location via the measuring rope. This activates the top support component 11, causing the lower partition plate 9 to move downwards. Consequently, the bottom ends of the two support rods 10 extend along the opening 202 until the bottom surface of the partition plate 9 is flush with the bottom inner wall of the channel 201. At this point, the two support rods 10 also extend horizontally under the support of the elastic body 12 above them, thus completing the spatial distribution of multiple water level sensors 13 on the support rods 10. During use, the multiple water level sensors 13 transmit the real-time groundwater level information to the control module, which then remotely sends it to the backend for staff to review, and displays the water level at different spatial points in the area on the display screen 8.

[0034] Example 2

[0035] A groundwater level monitoring device near the canal lining, such as Figure 1-2 As shown, in order to avoid the equipment being restricted by the urban power grid, this embodiment makes the following improvements based on embodiment 1: a solar panel 6 is fixed to the top outer wall of the bracket 1 by bolts, and a power supply 7 electrically connected to the solar panel 6 is fixed to one side inner wall of the bracket 1 by bolts; the solar panel 6 converts light energy into electrical energy and stores it in the power supply 7 to provide strong support for the normal operation of the equipment.

[0036] Furthermore, a locator 4 is fixed to the bottom inner wall of the bracket 1 by bolts; an alarm light 5 electrically connected to the control module is fixed to the top surface of the bracket 1 by bolts. When the groundwater level in the area exceeds the threshold, the control module will control the alarm light 5 to sound an alarm. The locator 4 and the alarm light 5 in this section enable staff to quickly locate the groundwater level monitoring component set near the channel lining, making it convenient to use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
