Description

Technical Field

[0001] The utility model relates to a floating pipeline siltation section scanning sensor, belonging to the technical field of urban drainage network monitoring. Background Art

[0002] Drainage network siltation detection is an important part of urban drainage network monitoring. The technical difficulty of drainage network siltation detection is how to collect on-site data signals of the drainage network. Chinese patent application CN202311011767.X, named "A drainage network siltation detection device and application method", uses an ultrasonic water depth sensor to detect drainage network siltation under the premise of knowing the diameter of the drainage pipe. However, several problems were found during the application process: 1. The cross-sectional shape of the drainage pipe siltation cannot be directly measured, such as whether the pipe is a round pipe or a square culvert; 2. The diameter of the drainage pipe cannot be directly measured; 3. When the pipe is not full, an additional manhole water level sensor needs to be used in conjunction; 4. The traction cable cannot automatically measure the length entering the pipe; 5. The power supply is placed in the handheld device, and the battery capacity is limited; 6. The float on the floating cable sinks into the top oil layer, causing a large cable friction, which limits the propeller's forward force. Utility Model Content

[0003] The utility model aims to provide a floating pipe siltation cross-section scanning sensor, which adds a rotating mechanism to an ultrasonic water depth sensor and can rotate to scan the distance in all directions in the drainage pipe, thereby depicting the shape and size of the pipe and the cross-sectional image of the siltation. It can detect the pipe shape, size and siltation degree of the underground drainage network, provide a basis for dredging maintenance and check whether the dredging effect is up to standard, thereby solving the problems existing in the background technology.

[0004] A floating pipeline siltation cross-section scanning sensor comprises a float, a cross-section scanning sensor, a bracket, an electric propeller and a connecting rod. There is at least one float. The connecting rod connects the float, the bracket and the electric propeller in series. The cross-section scanning sensor is arranged at the lower part of the bracket. The cross-section scanning sensor comprises a waterproof shell, a second circuit board, a waterproof stepping motor and an ultrasonic hydroacoustic sensor. The second circuit board and the waterproof stepping motor are arranged in the waterproof shell. The waterproof shell is filled with waterproof glue. The second circuit board is connected to a floating cable. The stepping motor shaft of the waterproof stepping motor extends out of the waterproof shell. The ultrasonic hydroacoustic sensor is matched with the stepping motor shaft, and the ultrasonic hydroacoustic sensor is connected to the second circuit board in the waterproof shell.

[0005] Furthermore, a non-contact distance measuring sensor is provided on the upper part of the floating body.

[0006] Furthermore, the electric propeller is arranged on the lower side of the connecting rod head end, and a trash rack is provided on the electric propeller; the end of the connecting rod is connected to a floating cable, and the floating cable is attached with a pull-back wire rope; a counterweight is provided at the lower part of the floating body.

[0007] Furthermore, a circuit board 1 is provided inside the floating body, the circuit board 1 is connected to the floating cable, and the circuit board 1 controls and drives the electric propeller.

[0008] Furthermore, the ultrasonic hydroacoustic sensor may also be connected to the stepper motor shaft via a universal joint.

[0009] Furthermore, the ultrasonic underwater acoustic sensor and the circuit board in the waterproof housing are connected in at least two ways:

[0010] 1. The ultrasonic underwater acoustic sensor is connected to the second circuit board through a waterproof conductive slip ring. The waterproof conductive slip ring is arranged on a slip ring bracket. The slip ring bracket is arranged on a waterproof shell. A cable is passed through the inside of the waterproof shell. One end of the cable is connected to the waterproof conductive slip ring, and the other end of the cable enters the waterproof shell and is connected to the second circuit board.

[0011] 2. The ultrasonic water acoustic sensor is connected to the second circuit board through a spiral cable. The spiral cable is matched on the stepper motor shaft. One end of the spiral cable is connected to the ultrasonic water acoustic sensor, and the other end of the spiral cable is connected to the second circuit board through a waterproof shell.

[0012] The monitoring and control host, floating cable, buoy, electric propeller, connecting rod, counterweight, trash rack, pull-back wire rope, circuit board one, non-contact ranging sensor, waterproof housing, circuit board two, waterproof stepping motor, ultrasonic hydroacoustic sensor, waterproof conductive slip ring, spiral cable and stepping motor shaft involved in the utility model are all well-known and commonly used technologies in the field.

[0013] The circuit board 1 and the circuit board 2 are both well-known and commonly used control circuits in the art. Controlling and driving corresponding components (devices) as needed is a skill known to those skilled in the art.

[0014] When the drainage pipe is full at high water level, the electric propeller of the floating pipe siltation section scanning sensor is started, and according to the length of the floating cable entering the manhole and at certain intervals, the ultrasonic hydroacoustic sensor signal scans the inside of the drainage pipe driven by the waterproof stepper motor; if the drainage pipe is not full, the ultrasonic hydroacoustic sensor scans the water-passing section of the underwater part of the drainage pipe, and the above-water part is detected by the non-contact ranging sensor on the upper side of the float.

[0015] The ultrasonic water acoustic sensor of the utility model can rotate and scan the distance in each direction of the drainage pipe, so as to depict the shape and size of the drainage pipe and the cross-sectional image of the siltation; the diameter of the drainage pipe is calculated by computer software, and the shape, size and siltation curve of the drainage pipe are generated according to the detected siltation scanning sections. Due to reasons such as ground subsidence, the sewage pipe will not be horizontal underground, but will bend up and down, so the siltation curve varies in depth. According to the siltation curve of the sewage pipe, it is determined whether siltation should be carried out, or whether the siltation effect meets the standard after siltation.

[0016] If there are too many floating objects in the drainage pipe and the trash rack of the electric propeller is blocked, the reverse thrust of the electric propeller is used to clear the blocked floating objects.

[0017] The beneficial effects of the utility model are as follows: a rotating mechanism is added to the ultrasonic water depth sensor, which can rotate to scan the distance in all directions in the pipeline, thereby depicting the shape and size of the drainage pipeline and the cross-sectional image of the siltation. It can detect the pipeline shape, size and siltation degree of the underground drainage network, provide a basis for dredging maintenance and check whether the dredging effect meets the standards.

[0031] Refer to the attached Figure 1 A floating object anti-hanging plate 22 is provided at the tail end of the connecting rod 8.

[0032] The ultrasonic underwater acoustic sensor 17 is connected to the circuit board 15 in the waterproof housing 14 in at least two ways:

[0033] Refer to the attached Figure 2In the first embodiment, the ultrasonic underwater acoustic sensor 17 is connected to the second circuit board 15 through a waterproof conductive slip ring 18.

[0035] The use process of this utility model: open the manhole cover, refer to the attached Figure 5 When the drainage pipe is not full, directly put the floating pipe sedimentation section scanning sensor 1 into the manhole and let it flow into the drainage pipe for detection; refer to the attached Figure 6 , when the drainage pipe is full of water at high water level, the floating pipe siltation section scanning sensor 1 is sent into the drainage pipe in the manhole for detection; when the drainage pipe is full of water at high water level, the electric propeller 7 of the floating pipe siltation section scanning sensor 1 is started, and according to the length of the floating cable 3 entering the manhole displayed by the meter 25, at a certain interval, the signal of the ultrasonic hydroacoustic sensor 17 is driven by the waterproof stepping motor 16 to scan the inside of the drainage pipe; if the drainage pipe is not full, the ultrasonic hydroacoustic sensor 17 scans the water section of the underwater part of the drainage pipe, and the above-water part is detected by the non-contact ranging sensor 13 on the upper side of the float;

[0037] The floating pipe siltation section scanning sensor 1 is sent into the drainage pipe in the manhole, and the existing technology "CNZL202420115490.9, a device for a floating sensor to enter the interior of a drainage pipe at a low flow rate" can be used through hydroacoustic scanning.

[0039] When the drainage pipe is full of high water level, the floating pipe siltation section scanning sensor 1 will float to the water surface when it moves forward to the next manhole. At this time, the pull-back wire rope 11 on the floating cable 3 is pulled down, and then the electric propeller 7 is turned on in reverse to push the floating pipe siltation section scanning sensor 1 down to the water surface into the drainage pipe. The pull-back wire rope 11 is also used to retrieve the floating pipe siltation section scanning sensor 1 from the drainage pipe. Another function of the pull-back wire rope is to prevent the floating pipe siltation section scanning sensor 1 from being stuck in the drainage pipe by tree roots or the like.
