Description

Technical Field

[0001] This utility model relates to the field of drift interception and drift removal, and in particular to a drift removal system for irrigation canals. Background Technology

[0002] Conventional debris interception and removal systems are primarily installed in the natural watershed upstream of the dam intake in hydropower projects to intercept floating debris and then retrieve it ashore. However, for artificial irrigation canals in water conservancy projects, there are currently few mature and efficient methods for intercepting and retrieving floating debris. It is well known that excessive floating debris in irrigation canals can affect water quality and the ecosystem. Floating debris, submerged in water, may slowly decompose and produce toxic substances and gases, polluting the water body and the surrounding environment. Too much floating debris can also clog irrigation channels, affecting water flow and leading to poor irrigation results. Organic matter in suspended solids can easily undergo anaerobic fermentation after sedimentation, producing foul odors and harmful substances, further deteriorating water quality and affecting crop growth. Suspended solids may also carry heavy metals, bacteria, viruses, and other harmful substances; if used as drinking water, this could cause various health problems.

[0003] Among existing floating debris removal equipment, the Chinese utility model patent for "River Floating Debris Cleaning and Collection" is relevant.

[0004] The device, disclosed in patent announcement number CN220746850U, involves a horizontally positioned drift barrier on a river channel for intercepting floating debris. A conveying mechanism is also horizontally positioned on the river channel and correspondingly arranged with the drift barrier. The conveying mechanism is driven and connected to a pusher plate, which drives the pusher plate to move along the drift barrier to push the floating debris to the bank. The first end of the conveying mechanism and the first end of the drift barrier are rotatably connected to the bank, and the second end of the conveying mechanism and the second end of the drift barrier are connected to a float. A traction mechanism is located on the bank near the first end of the conveying mechanism and is driven and connected to the float, which tractions the conveying mechanism and the drift barrier to rotate and avoid the river channel. In this way, the drift barrier first intercepts the floating debris on the river channel, and then the conveying mechanism drives the pusher plate to gather and push the floating debris to the bank, thus facilitating subsequent processing.

[0005] The floating debris collection box is embedded in the bank embankment. The river floating debris cleaning and collection device also includes a support structure and a hoisting mechanism. The hoisting mechanism is set on the support structure and is driven to lift the floating debris collection box.

[0006] The above document has the following problems:

[0007] 1. The technical solution described in the aforementioned comparative document intercepts floating objects on the river channel by using a float-blocking ditch, and then uses a conveying mechanism to drive a float-pushing plate to gather and push the floating objects to the bank, thus facilitating subsequent processing. However, the irrigation canal is narrow and not suitable for setting up large cleaning devices such as conveying mechanisms in the river channel, as this would obstruct water flow, reduce flow rate, and affect irrigation.

[0008] 2. Using a float collection box to store floating debris for later processing can affect water quality and the ecosystem in irrigation canals. Floating debris soaking in water may slowly decompose and produce toxic substances and gases, polluting the water and the surrounding environment and affecting crop growth. Summary of the Invention

[0009] The purpose of this invention is to overcome the above-mentioned problems of the prior art and to propose an irrigation canal cleaning system that solves the problem that the cleaning devices in the prior art are not suitable for cleaning irrigation canals.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] A canal cleaning system, characterized by comprising a drift interceptor, a cleaning mechanism, and a transfer vehicle.

[0012] The drift barrier is installed inside the irrigation canal, and the drift removal mechanism is installed on the road beside the irrigation canal for cleaning and transferring the retrieved floating objects. The transfer vehicle is located in front of the drift removal mechanism. The drift removal mechanism includes a drift retrieval mechanism and a self-propelled vehicle. The rotation drive device of the rotating telescopic arm on the drift retrieval mechanism is connected to the self-propelled vehicle, and the rotating telescopic arm is connected to a retrieval bucket. The fixed anchor points at both ends of the traction main cable on the drift barrier are fixed on both sides of the irrigation canal, and the drift barrier box and the hanging grid are installed on the traction main cable.

[0013] The rotary drive device is equipped with a rotary drive motor, which is connected to the transmission gear on the rotary drive device.

[0014] The rotating telescopic boom includes a rotating drive device, a support arm, a boom hydraulic cylinder, a boom, a forearm hydraulic cylinder, a forearm, and a bucket hydraulic cylinder; one end of the support arm is connected to the rotating telescopic mechanism, and the other end is connected to the boom; the boom, forearm, and forearm are connected in sequence; the forearm is connected to the bucket; one end of the boom hydraulic cylinder is located at the bottom of the support arm, and the other end is located at the lower part of the boom; one end of the forearm hydraulic cylinder is connected to the end of the forearm, and the other end is located at the upper part of the boom; one end of the forearm hydraulic cylinder is connected to the end of the forearm, and the other end is located at the upper part of the forearm; one end of the bucket hydraulic cylinder is connected to the bucket, and the other end is located at the upper part of the forearm.

[0015] The rotary drive device is equipped with a telescopic arm motor, which is connected to a gear pump located inside the support arm.

[0017] The drive trolley is equipped with a drive motor, which drives a four-wheel synchronous gear that makes the four wheels of the trolley move synchronously.

[0018] The advantages of using this utility model are:

[0019] I. Compared with the prior art, this utility model effectively treats floating objects in irrigation canals and other waterways by using a combination of a drift interceptor, a drift removal mechanism, and a transfer vehicle, without affecting the flow rate of the irrigation canal itself.

[0020] Second, compared with the prior art, this utility model does not set up a device for collecting floating objects, but adopts a float retrieval mechanism to retrieve and treat floating objects in a timely manner, which will not cause pollution to the water body and the surrounding environment.

[0021] Third, the entire process of dredging the floats in this utility model is remotely controlled, requiring only one remote operator to complete the entire dredging operation, which greatly improves cleaning efficiency. Attached Figure Description

Detailed Implementation

[0027] Example 1

[0028] A canal debris removal system includes a debris-blocking dam 1, a debris removal mechanism, and a transfer vehicle 3.

[0029] The float-blocking slab 1 is installed inside the irrigation canal, and the float-clearing mechanism is installed on the road beside the irrigation canal for cleaning and transferring the retrieved floating objects. The transfer vehicle 3 is located in front of the float-clearing mechanism. The float-clearing mechanism includes a float-collecting mechanism 4 and a self-propelled vehicle body 5. The rotating drive device of the rotating telescopic arm 6 on the float-collecting mechanism 4 is connected to the self-propelled vehicle body 5, and the rotating telescopic arm 6 is connected to a scooping bucket 7. The fixed anchor points 14 at both ends of the traction main cable 12 on the float-blocking slab 1 are fixedly installed on both sides of the irrigation canal, and the float-blocking box 11 and the hanging grid 13 are installed on the traction main cable 12.

[0030] The rotary drive device is equipped with a rotary drive motor, which is connected to the transmission gear on the rotary drive device.

[0031] The rotating telescopic boom 6 includes a rotating drive device, a support arm 15, a boom hydraulic cylinder 16, a boom 17, a forearm hydraulic cylinder 18, a forearm 19, a forearm hydraulic cylinder 20, a forearm 21, and a bucket hydraulic cylinder 22.

[0032] One end of the support arm 15 is connected to the rotary telescopic mechanism, and the other end is connected to the upper arm 17; the upper arm 17, the lower arm 19, and the forearm 21 are connected in sequence; the forearm 21 is connected to the bucket 7; one end of the upper arm hydraulic cylinder 16 is located at the bottom of the support arm 15, and the other end is located at the lower part of the upper arm 17; one end of the lower arm hydraulic cylinder 18 is connected to the end of the lower arm 19, and the other end is located at the upper part of the upper arm 17; one end of the forearm hydraulic cylinder 20 is connected to the end of the forearm 21, and the other end is located at the upper part of the lower arm 19; one end of the bucket hydraulic cylinder 22 is connected to the bucket 7, and the other end is located at the upper part of the forearm 21.

[0033] The rotary drive device is equipped with a telescopic arm motor, which is connected to a gear pump located inside the support arm 15.

[0034] The self-propelled vehicle body 5 includes a fixed support 9 and a drive trolley 10. The fixed support 9 is fixedly installed above the drive trolley 10 and is fixedly connected to the rotation drive structure of the rotating telescopic arm 6.

[0035] The drive trolley 10 is equipped with a drive motor, which drives a four-wheel synchronous gear that enables the four wheels of the trolley to move synchronously.

[0036] The drift barrier 1 is positioned at the highest point of the irrigation canal. The main traction cable 12 can be appropriately long to ensure proper interception of floating debris during the transition from the highest to the lowest water level. When operating at the highest water level for drift interception, the catenary sag of the main traction cable 12 is relatively large; when operating at the lowest water level, the drift barrier 1 automatically adapts to spatial changes according to the water level, at which point the catenary sag of the main traction cable 12 decreases.

[0037] The irrigation canal cleaning equipment is self-propelled (wheeled or tracked) and can be remotely controlled for short-range movement or relocation. The cleaning mechanism 2 includes a self-propelled vehicle body 5, a powertrain, a fixed support 9, a rotary drive device 8, and a rotary telescopic arm 6. The rotary drive device 8 mainly consists of a rotary reducer and a rotary support, which drives the rotary telescopic arm 6, mounted on it, to rotate 360° via a rotary drive motor. The rotary telescopic arm 6 generally consists of a support arm 15, a large arm 17, a small arm 19, a front arm 21, and corresponding hydraulic cylinders. Under the coordinated action of multiple hydraulic cylinders driven by the telescopic arm motor, the rotary telescopic arm 6 can extend from near to far and adjust its height, meeting the requirements for omnidirectional float retrieval within a certain range. The float retrieval mechanism mainly consists of a retrieval bucket 7, either a single bucket or a clamshell type, which performs float retrieval operations under the control of hydraulic cylinders.

[0038] The transfer vehicle 33 is simply a general-purpose van with a box, which is responsible for transferring the collected floating debris.

[0039] Typically, roads are built on both sides or one side of irrigation canals. Due to the obstruction of the drift barrier 1 in the irrigation canal, a large amount of floating garbage will accumulate in front of the drift barrier 1. The special drift cleaning equipment for irrigation canals is placed in a position that is convenient for retrieval of floating garbage. The special drift cleaning equipment for irrigation canals is operated by a special remote control to retrieve the floating garbage, and then transported by a transfer vehicle 3 to a planned location for harmless treatment.

[0040] When the floating debris retrieval work begins, the cleaning mechanism 2 is moved to a designated position close to the drift barrier 1, and the transfer vehicle 3 is moved to the designated position. The location of the floating debris intercepted by the drift barrier 1 is determined, and the front bucket 7 of the rotating telescopic arm 6 in the cleaning mechanism 2 is controlled by an external remote control to retrieve the floating debris. After the floating debris is retrieved from the water, it is transferred to the transfer vehicle 3, and then transported by the transfer vehicle 3 to the planned treatment area. The three work together to achieve the cleaning of the irrigation canal.
