Description

Technical Field

[0001] The invention relates to the technical field of building municipal engineering, and in particular to a silt early warning and desilting device and method for a road sedimentation well. Background Art

[0002] Urban drainage is an important part of urban infrastructure. High-grade highway drainage is an important measure to ensure the long-term safe use of highways. Sludge sedimentation wells are devices used to store and treat sludge. The above projects all require the use of culverts, culverts or culverts for drainage. Since runoff formed on urban or highway pavements during rainy seasons often carries varying amounts of silt, during underground drainage or centralized treatment, silt is prone to settle when the terrain conditions are met, causing siltation in the drainage system. Setting up sedimentation wells at required locations is one of the important means to solve the siltation problem. Sedimentation wells need to be cleaned of silt from time to time during use, otherwise excessive silt in the sedimentation well will seriously affect the normal use of drainage pipes or channels. At present, the time to clean the sedimentation wells is determined by visual inspection and some regular speculations of the staff. This method is unreasonable. First, if it is not cleaned for a long time, it is easy for the sediment at the bottom of the well to form sticky and solid blocks, making it difficult to remove the silt. The use of conventional sand suction pumps or sludge pumps will not achieve the expected silt removal effect. In addition, regular silt removal may lead to short silt removal intervals, and personnel and equipment cannot be used efficiently, wasting manpower and material resources. In addition, manual on-site silt removal will also lead to the ineffective control of on-site pollution, seriously affecting the urban environment. Finally, manual silt removal may cause methane poisoning to on-site workers, and the manual labor intensity is high. Summary of the invention

[0046] The first moisture detector probe 400 includes a probe fixing seat 401, and a plurality of parallel probes 403 (including 3 probes in this embodiment) are arranged on one side of the probe fixing seat 401. A transmission cable 3 and a cable fixing cap 406 are connected to the top of the probe fixing seat 401. The first moisture detector probe 400 is threadedly connected to the wire socket 225 on the first detection instrument box fixing seat 220 through the transmission cable 3 and its cable fixing cap 406 connected thereto.

The second T-shaped fixing cap 405 is pre-buried in the sedimentation well kiln body 2 by punching, and the first moisture detector probe 400 can be firmly fixed to the side wall of the sedimentation well kiln body 2 through the third fixing screws 404.

[0047] It should be pointed out that, in this embodiment, the three probes 403 are at the same horizontal height, and the detection accuracy of the silt height can be improved by providing multiple probes 403 .

[0048] Example 2, reference Figure 6-7A road sedimentation well silt early warning and silt removal device comprises a sedimentation well 100, a second moisture detection instrument 500, a silt removal mechanism 300, and a second moisture detection instrument probe 600. The sedimentation well 100 comprises a sedimentation well kiln body 2 embedded in a soil matrix 7 and a sedimentation well cover body 1 matched therewith, and an overflow pipe 6 pre-buried in the soil matrix 7 is connected to one side of the sedimentation well kiln body 2; the second moisture detection instrument 500 is fixedly arranged on the upper side of the inner wall of the sedimentation well kiln body 2, and the second moisture detection instrument probe 600 fixedly connected at the bottom end of the second moisture detection instrument 500 is immersed in the water layer 5 on the lower side of the sedimentation well kiln body 2; the silt removal mechanism 300 can be placed in the sedimentation well kiln body 2 and is wirelessly connected to the second moisture detection instrument 500.

[0049] In this embodiment, the second moisture detection instrument 500 is integrated with the second moisture detection instrument probe 600; the second moisture detection instrument 500 includes a detection instrument box, and the second moisture detection instrument probe 600 is fixedly arranged at the bottom of the detection instrument box; the detection instrument box includes a transceiver antenna 01, a protection mechanism 02, and a box body 03, and the top of the box body 03 is fixedly provided with the transceiver antenna 01 and the protection mechanism 02; the upper back side of the box body 03 is provided with a second fixing plate 511, and the second fixing plate 511 is fixed to the sedimentation well kiln body 2 by pre-buried in the third T-shaped fixing cap 512 and the fourth fixing screw 513. In this embodiment, the installation requirements of the integrated moisture detection instrument meet the requirements that the installation height of the transceiver antenna 01 and the protection mechanism 02 at the top of the detection instrument box is greater than the lower liquid level of the overflow pipe 6, so as to avoid the long-term immersion of the connecting part of the transceiver antenna 01, the protection mechanism 02 and the box body 03; the second moisture detection instrument probe 600 includes multiple probes. In this embodiment, the second moisture detection instrument probe 600 includes three probes, and the multiple probes can effectively improve the detection accuracy.

[0050] In Example 1 and Example 2, the moisture detection instrument adopts the frequency domain reflection principle (FDR), that is, the electromagnetic wave of a certain frequency is emitted by the sensor, and the electromagnetic wave is transmitted along the probe, and returns after reaching the bottom, and the voltage output by the probe is detected. Since the change of the dielectric constant of the soil usually depends on the water content of the soil, the water content of the soil can be calculated from the relationship between the output voltage and the water content. Water is the main factor determining the dielectric constant of the soil. Measuring the dielectric constant of the soil can directly and stably reflect the true water content of various soils. The probes of the moisture detector probes 400 and 600 are made of 316 stainless steel with high corrosion resistance and electrolysis resistance. When working, the total water content of the cylindrical range of about 6cm in diameter and 10cm in length around the probe can be measured. Under normal circumstances, the probe is in the water, and the water value measured by the probe is 100%. When the silt height gradually fills the probe, the water content around the probe will gradually decrease. When the water content shows 50-60%, the probe is basically surrounded by silt. This water content data can be used to determine whether the silt height in the sedimentation well 100 needs to be cleaned.

[0051] In addition, the detection instrument box includes a battery, a communication module, a single-chip microcomputer, a timing device, an alarm device and a control circuit. The communication module, the timing module, the alarm module and the single-chip microcomputer are electrically connected, and the battery provides power for the above devices. The above functions can be integrated through existing technical units and will not be described in detail here. When working, the single-chip microcomputer is started by the timing device to start the control circuit to detect the moisture in the sedimentation well 100. The moisture detector probe 400, 600 detects the height of the water layer 5 in the sedimentation well according to the instructions of the moisture detector 200, 500. The conventional detection frequency is once a day; when the silt layer 4 in the sedimentation well 100 rises to the height of the moisture detector probe 400, 600 and gradually buries its probe, its detected moisture content drops to a preset value, and its electrical signal is transmitted to the moisture detector 200, 500. The moisture detector 200, 500 converts its electrical signal into a radio signal and transmits it to the control center through the antenna 01, and issues a dredging alarm.

A jet pump 329 is also arranged on the periphery of the third mounting plate 321, and the jet tube 3211 at the lower end thereof extends to the lower end of the third mounting plate 321.
