Description

Technical Field

[0001] The utility model relates to a water conservancy pipeline, in particular to a water conservancy pipeline of a water conservancy project applied in the field of water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, ferries, rafts, fishways, etc. to achieve their goals. Pipelines are indispensable equipment in water conservancy projects, mainly used for dredging and diversion of water.

[0003] When water pipes used in water conservancy projects are transporting water, desilting ports are generally set in the pipes to regularly clean up some settled silt, thereby reducing the probability of pipe blockage. However, when the staff are inspecting and repairing, the amount of silt deposited in each desilting port is not the same, some are more, and some are less. In the prior art, the general way for the staff to deal with it is to open the desilting ports one by one for cleaning, resulting in low efficiency of the staff in cleaning the pipes. Utility Model Content

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the utility model is that during dredging, no matter how much sediment is deposited, the dredging ports need to be opened one by one for cleaning, resulting in low efficiency of pipeline cleaning by the staff.

[0005] In order to solve the above problems, the utility model provides a water conservancy pipeline of a water conservancy project, comprising two pipeline bodies and a sand accumulation pipe connected between the two pipeline bodies, the sand accumulation pipe is fixedly connected to the pipeline body by a plurality of bolts, the upper and lower ends of the sand accumulation pipe are respectively fixedly connected with an upper expansion pipe and a silt removal port, the upper expansion pipe and the silt removal port away from the mouth of the sand accumulation pipe are sealed with a silt removal cover, a T-shaped groove is cut on the upper surface of the lower silt removal cover, a monitoring pipe is vertically penetrated in the sand accumulation pipe, the lower end of the monitoring pipe is rotatably connected to the T-shaped groove, the upper end of the monitoring pipe movably penetrates the upper silt removal cover and extends to above the upper expansion pipe, the upper end cover of the monitoring pipe is provided with a spiral cover, and a plurality of light sensors are installed on the side wall of the silt removal port, and the detection ends of the plurality of light sensors are facing the monitoring pipe.

[0006] In the water conservancy pipelines of the above-mentioned water conservancy projects, by setting up monitoring pipes, the internal sediment settlement situation can be understood without opening the dredging outlets, and dredging can be carried out specifically at the dredging outlets with more sediment, without opening the dredging outlets one by one for dredging, which effectively reduces the workload of the staff and improves the dredging efficiency.

[0007] As a further improvement of the present application, a plurality of light sensors are located on the inner wall of the dredging outlet close to the water inlet side of the pipe body, and the lowest light sensor is not lower than the first three-point point from bottom to top of the dredging outlet.

[0008] As a further improvement of the present application, the monitoring tube is a hard transparent structure, and the outer ends of the monitoring tube corresponding to the upper dredging cover are wrapped with a rubber layer, through which the monitoring tube and the dredging cover are interference fit.

[0009] As a further improvement of the present application, a magnetic core is inserted inside the monitoring tube, an external rubbing ring is sleeved on the outer end of the monitoring tube, a positioning rope is fixedly connected to the upper end of the magnetic core, and the external rubbing ring and the magnetic core correspond to each other and are attracted to each other.

[0010] As a further improvement of the present application, the outer rubbing ring is an annular rubber structure with an iron sheet attached to the outside, the magnetic core has an interference fit with the inner wall of the monitoring tube, the total length of the positioning rope is greater than the height of the monitoring tube, and after each use, the magnetic core is pulled upward by the positioning rope to reset it so that the magnetic core is located in the upper expansion tube.

[0011] As another improvement of the present application, two stirring rods are fixedly connected to the outer end of the magnetic core, and the ends of the two stirring rods away from the monitoring tube are inclined upward, and a transparent plate is fixedly inlaid on the outer end of the dredging port, and the bottom of the transparent plate is not lower than the midpoint of the dredging port.

[0012] In summary, when the staff arrives at the dredging port, they can first unscrew the screw cap, take out the positioning rope, so that its end is outside the monitoring tube, and then use a slender tool to push the magnetic core downward to drive the outer wiping ring downward, and then pull the positioning rope to make the magnetic core drive the outer wiping ring upward, so that the impurities adhering to the surface of the monitoring tube can be wiped off, and then a beam of light is emitted into the monitoring tube. Then, according to the light signals received by multiple light sensors, the sediment deposition situation can be judged. When the deposited sediment is large, unscrew the dredging cap for dredging. Compared with the existing technology, it effectively reduces the workload of the staff and improves the dredging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0022] The first implementation method:

[0023] Figure 1-3 A water conservancy pipeline of a water conservancy project is shown, comprising two pipeline bodies 1 and a sand accumulation pipe 2 connected between the two pipeline bodies 1, the sand accumulation pipe 2 is fixedly connected to the pipeline body 1 by a plurality of bolts 201, the upper and lower ends of the sand accumulation pipe 2 are respectively fixedly connected with an upper expansion pipe 31 and a silt removal port 32, the upper expansion pipe 31 and the silt removal port 32 away from the mouth of the sand accumulation pipe 2 are both sealed with a silt removal cover 301, a T-shaped groove 302 is cut on the upper surface of the lower silt removal cover 301, a monitoring pipe 4 is vertically penetrated in the sand accumulation pipe 2, the lower end of the monitoring pipe 4 is rotatably connected to the T-shaped groove 302, the upper end of the monitoring pipe 4 movably penetrates the upper silt removal cover 301 and extends to the top of the upper expansion pipe 31, the upper end cover of the monitoring pipe 4 is provided with a screw cover 401, and a plurality of light sensors 5 are installed on the side wall of the silt removal port 32, and the detection ends of the plurality of light sensors 5 are facing the monitoring pipe 4.

[0024] It is worth noting that the light sensor 5 can be connected to the staff's mobile phone APP for signal connection through wireless transmission technology. This part of the content is existing technology and will not be elaborated on here. When monitoring the sediment deposition situation, the staff can directly receive the data of multiple light sensors 5 through the mobile phone APP; in addition, a display screen for displaying the data on multiple light sensors 5 can also be installed on the sand accumulation pipe 2. This is also existing technology and will not be elaborated on here.

[0025] A plurality of light sensors 5 are located on the inner wall of the dredging opening 32 close to the water inlet side of the pipe body 1, and the lowest light sensor 5 is not lower than the first three points from the bottom to the top of the dredging opening 32. Figure 4 During detection, the more sediment is deposited, the more light sensors 5 are blocked. When light is emitted into the monitoring tube 4, only the light sensors 5 above the sediment can receive the light signal. Therefore, based on the situation of multiple light sensors 5 receiving light signals, the sediment deposition situation in the dredging port 32 can be roughly judged, which is convenient for the staff to judge whether it is necessary to open the dredging port for dredging. Compared with the existing technology, there is no need to open the dredging port one by one for dredging, thereby effectively reducing the workload of the staff and improving the dredging efficiency.

[0026] The monitoring tube 4 is a hard transparent structure, and the outer ends of the monitoring tube 4 corresponding to the upper dredging cover 301 are wrapped with a rubber layer, through which the monitoring tube 4 and the dredging cover 301 are interference fit.

[0027] like Figure 5 A magnetic core 41 is inserted into the monitoring tube 4, and an outer rubbing ring 42 is sleeved on the outer end of the monitoring tube 4. A control rope 43 is fixedly connected to the upper end of the magnetic core 41. The outer rubbing ring 42 and the magnetic core 41 correspond to each other and are adsorbed on each other. The outer rubbing ring 42 is an annular rubber structure with an iron sheet attached to the outside. The magnetic core 41 and the inner wall of the monitoring tube 4 have an interference fit. The total length of the control rope 43 is greater than the height of the monitoring tube 4. After each use, the magnetic core 41 is pulled upward by the control rope 43 to reset the magnetic core 41, so that the magnetic core 41 is located in the upper expansion tube 31. The outer rubbing ring 42 can be controlled by the magnetic core 41 to move up and down outside the monitoring tube 4, thereby effectively wiping impurities adhered to its surface, making it light transmittance good, so that the subsequent light sensor 5 is not easy to receive light signals due to excessive impurities on its surface, thereby effectively improving the monitoring results of sand accumulation using the monitoring tube 4 and the light sensor 5 to be more accurate.

[0028] A rear magnetic ring is embedded inside the upper dredging cover 301. After the impurities on the surface of the monitoring tube 4 are cleaned, when the magnetic core 41 is taken out, the outer wiping ring 42 moves up with the magnetic core 41 and contacts the dredging cover 301. Under the action of the magnetic ring, the iron sheet on the outer wiping ring 42 can be adsorbed so that the outer wiping ring 42 is restricted in the upper expansion tube 31, which is not easy to block the monitoring tube 4 and affect the reception of the optical signal of the light sensor 5.

[0029] In summary, when the staff arrives at the dredging port, they can first unscrew the screw cover 401, take out the position control rope 43 first, so that its end is outside the monitoring tube 4, and then use a slender tool to push the magnetic core 41 downward, so that it drives the outer wiping ring 42 to move downward, and then pull the position control rope 43 to make the magnetic core 41 drive the outer wiping ring 42 to move upward, so that the impurities adhering to the surface of the monitoring tube 4 can be wiped off, and finally, continue to pull the position control rope 43 to remove the outer wiping ring 42 from the monitoring tube 4, and then shine a beam of light into the monitoring tube 4, and then judge the sediment deposition situation according to the light signals received by multiple light sensors 5. When the deposited sediment is large, unscrew the dredging cover 301 for dredging. Compared with the prior art, there is no need to open the dredging ports one by one for dredging, thereby effectively reducing the workload of the staff and improving the dredging efficiency.

[0030] After the dredging is finally completed, the magnetic core 41 is inserted into the monitoring tube 4 , and the position control rope 43 is also placed into the monitoring tube 4 , and the screw cover 401 is closed.

[0031] The second implementation method:

[0032] On the basis of the first embodiment, this embodiment adds a stirring rod 61 and a transparent plate 62, and does not provide a light sensor 5. The rest of the parts are consistent with the first embodiment.

[0033] Figure 6 As shown, two stirring rods 61 are fixedly connected to the outer end of the magnetic core 41, and the ends of the two stirring rods 61 away from the monitoring tube 4 are inclined upward, and a transparent plate 62 is fixedly embedded on the outer end of the dredging port 32, and the bottom of the transparent plate 62 is not lower than the midpoint of the dredging port 32.

[0034] Each time the sediment deposition in the sand accumulation pipe 2 is detected, the monitoring pipe 4 can be moved back and forth and drilled several times to allow the stirring rod 61 to loosen the settled sediment and make the upper surface of the deposited sediment tend to be horizontal. Then a beam of light is injected into the monitoring pipe 4. By observing whether the light leakage at the transparent plate 62 can be observed, it can be judged whether the sediment deposition amount in the dredging port 32 is too much. It can directly replace the light sensor 5. In specific implementation, a suitable implementation method can be selected according to actual needs.

[0035] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
