Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitoring and early warning technology, and in particular to a monitoring and early warning device for frost heave deformation of water conservancy engineering channels. Background Technology
[0002] When the soil moisture content in irrigation canals is high and the temperature drops below 0°C, the water freezes and expands, generating frost heave (which can reach 0.1–1 MPa), which can lead to damage such as cracking of concrete linings, loosening of masonry, and landslides on canal slopes. For example, in a certain irrigation area in Northeast my country, frost heave in winter caused large-scale peeling of the canal lining, resulting in leakage and collapse during the water conveyance period, directly threatening the safety of downstream villages.
[0003] By monitoring frost heave deformation (such as displacement, stress, and water content) in real time, early warnings can be issued before the frost heave force exceeds the structural bearing capacity, thus preventing accidents such as dam failure and breaches caused by "operating with defects." Therefore, frost heave monitoring and early warning devices are essential. However, existing frost heave monitoring and early warning devices require manual guidance to continuously move monitoring points along the entire water conservancy project channel for testing. The operation steps are cumbersome, requiring constant relocation and construction of monitoring platforms. In addition, the measured monitoring data cannot be directly reflected on the water conservancy project channel. Testing personnel and analysis and evaluation personnel need to spend a long time handing over and sorting data before they can assess the frost heave risk. They cannot obtain frost heave risk information directly and quickly. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a monitoring and early warning device for frost heave deformation of water conservancy engineering channels, comprising a track and a platform. The platform is located on one side of the track, and an installation box is fixedly embedded in the middle of the platform. A time domain reflectometer is inserted inside the installation box. A fixed column is fixedly embedded in one corner of the platform. Multiple marking rods are equidistantly inserted on the fixed column. Each marking rod includes a head rod, a color rod, and a fixed cone. A cavity is opened inside the head rod, and a rotating shaft is rotatably connected to the inner wall of the cavity. A transmission rod is fixedly connected to the top of the rotating shaft, and a roll of marking paper is wound on the rotating shaft. A through groove is opened on one side wall of the head rod, and the middle of the roll of marking paper moves through the through groove.
[0006] As a preferred embodiment of this utility model, a sliding plate is slidably connected to one side wall of the track, and the back of the platform is fixedly connected to the front of the sliding plate.
[0007] In a preferred embodiment of this invention, the bottom end of the head rod is fixedly connected to the top end of the color rod, and the top end of the fixing cone is fixedly connected to the bottom end of the color rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model, by setting up a track, slide plate, and platform, and with the installation box embedded in the platform, allows the time domain reflectometer to be fixedly installed at multiple interval monitoring points in the water conservancy project channel, forming a detection platform to quickly measure the current soil moisture content and other conditions to determine the frost heave risk level.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution for a monitoring and early warning device for frost heave deformation in water conservancy engineering channels:
[0022] according to Figure 1 , Figure 2 and Figure 3 , Figure 4 As shown, a monitoring and early warning device for frost heave deformation in water conservancy engineering channels includes a track 1 and a platform 3. The track 1 is made of 304 stainless steel, and its length is customized according to the channel monitoring range. The surface is treated with rust prevention, and the tensile strength is ≥520MPa to ensure long-term use in humid environments. The platform 3 is located on one side of the track 1, and a mounting box 4 is fixedly embedded in the middle of the platform 3. A time domain reflectometer 5 is inserted inside the mounting box 4. The mounting box 4 is injection molded from ABS engineering plastic with a wall thickness of 5mm and built-in shock-absorbing sponge. The time domain reflectometer 5 (TDR) model is TRIME-PICO. IPH, a fixed post 6 is fixedly embedded in one corner of the platform 3. Multiple marking rods are inserted at equal intervals on the fixed post 6. The marking rods include a head rod 7, a color rod 17 and a fixed cone 8. The surface of the color rod 17 is sprayed with weather-resistant fluorocarbon paint, and the colors are distinguished according to the risk level (red / orange / yellow / green, corresponding to different moisture content ranges). The head rod 7 has a cavity inside. The inner wall of the cavity is rotatably connected to a rotating shaft 15. The top of the rotating shaft 15 is fixedly connected to a transmission rod 14. A marking paper roll 12 is wound on the rotating shaft 15. A through groove 13 is opened on one side wall of the head rod 7. The middle part of the marking paper roll 12 moves through the through groove 13.
[0023] A slide plate 2 is slidably connected to one side wall of track 1. The back of platform 3 is fixedly connected to the front of slide plate 2. The bottom end of head rod 7 is fixedly connected to the top end of color rod 17. The top end of fixed cone 8 is fixedly connected to the bottom end of color rod 17.
[0024] The middle part of the fixed post 6 has multiple slots, and multiple marking rods pass through the multiple slots respectively. The inner wall of the slot has two built-in grooves 9. A pair of compression springs 11 are fixedly connected to one side of the inner wall of the built-in groove 9. One end of the pair of compression springs 11 is fixedly connected to a clamping plate 10. The side wall of the clamping plate 10 fits against the side wall of the color rod 17.
[0025] A resistance block 16 is fixedly connected to the inner wall of the top of the cavity, and the middle part of the transmission rod 14 passes through the resistance block 16.
[0026] In practical use, this utility model, a monitoring and early warning device for frost heave deformation prevention in water conservancy engineering channels, allows the operator to install a track on the side wall of the channel, close to the soil layer. When monitoring for frost heave tendency in the surrounding soil is required, the sliding plate 2 can be adjusted to move along the track 1, stopping at intervals to install the time-domain reflectometer 5 inside the mounting box 4. This quickly establishes a monitoring platform on the soil layer, allowing probes to be inserted into the surrounding soil layer for detection. The higher the moisture content and the greater the temperature drop, the higher the risk of frost heave, requiring focused monitoring. The measured frost heave risk level can be pre-assigned to multiple colored bars 17, such as bars painted in red, orange, yellow, green, cyan, blue, and purple, with progressively increasing frost heave risk levels. After each moisture content monitoring, the device can... The marker pole is inserted into the measured soil area to quickly mark the soil frost heave risk at that location. When observing the entire water conservancy project channel later, the soil frost heave risk of the whole line can be quickly grasped, and the probability of frost heave can be warned in advance and the status can be analyzed. The specific operation is as follows: For example, if the current soil moisture content is low, that is, the frost heave risk is low, the red-colored pole 17 can be manually pressed down and its bottom fixing cone 8 is inserted into the soil, so that the marker pole is stably placed in the measured soil for marking. At the same time, the marking paper roll 12 in the head pole 7 can be pulled out during the test to record the specific measurement data such as moisture content. In this way, after observing the frost heave risk level divided by color, pulling out the marking paper roll 12 in the head pole can show detailed frost heave monitoring data information, so as to achieve a more accurate frost heave risk assessment.
