Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy engineering equipment, and in particular relates to river channel desilting equipment for water conservancy construction. Background Art

[0002] River dredging in water conservancy construction refers to the process of removing impurities such as mud, silt, etc. from the river channel by manual or mechanical means in order to ensure the smooth flow of waterways and prevent river siltation. At present, river dredging in water conservancy construction faces problems such as low dredging efficiency, unsuitable equipment size, and insufficient environmental considerations. Among the common river dredging methods currently used, the use of high-pressure water cutting or suction is common in manual dredging operations. The workload is huge, the working environment is harsh, the cleaning process is labor-intensive and time-consuming, and it is difficult to clean thoroughly. Small excavators that can penetrate deep into the riverbed, such as trembling excavators, require repeated manual excavation and transfer, which is a large workload and workers are in a sludge environment for a long time, seriously affecting their health.

[0003] Many river dredging systems utilize traditional mechanical methods, such as excavators and forklifts. These methods are complex to operate, inefficient, and highly dependent on human resources. These devices and processes often require significant manpower and time, and are prone to environmental damage. Traditional dredging methods require frequent manual intervention and monitoring, resulting in low efficiency. Furthermore, the large amount of sediment generated during dredging requires treatment and disposal, resulting in high costs and increasing the economic burden of dredging. Traditional dredging processes require operators to enter the waterway to perform operations, which carries operational risks such as mud collapse and drowning. Furthermore, the specialized nature of dredging equipment and tools requires operators to possess specific expertise and skills, and a lack of standardized training and operating guidelines makes accidents more likely. Traditional dredging methods often cannot precisely control the scope and depth of dredging, potentially impacting the river's ecological environment, such as damaging riverbed and bankside vegetation and disrupting aquatic habitats. Traditional dredging equipment often lacks real-time monitoring and data feedback capabilities, preventing timely information on river siltation and dredging effectiveness, hindering decision-making and optimizing dredging plans.

[0004] To solve these problems, it is necessary to develop a new generation of river dredging equipment that combines advanced technology and innovative processes to improve the efficiency and quality of dredging, reduce dependence on human resources, protect the environment and ensure the safety of operators. Summary of the Invention

Implementation Method

[0031] The present invention will be further described below with reference to the accompanying drawings and examples. Example

[0032] A water conservancy construction river dredging equipment, such as Figure 1 As shown, it mainly includes a locomotive mechanism 1, a folding frame 2, a composite track 3, an auxiliary support mechanism 4, a sludge treatment unit 5, a collection and transfer unit 6, a high-pressure cutting unit 7, etc.

[0033] The locomotive mechanism 1 includes a vehicle body 11, a crawler track 12, a bracket 13, a conjoined fixing frame 14, a high-pressure pump assembly 15 and a buffer water tank 16, wherein, as Figure 1 In the embodiment, tracks 12 are installed on both sides of the vehicle body 11, and a battery or an external power supply is installed inside the vehicle body 11, preferably an external power supply. The vehicle body 11 is equipped with a wireless transceiver module and a remote controller, and the vehicle's movement and steering are controlled by remote control. There are independent tracks 12 on both sides of the vehicle body 11, front and back, so that the vehicle can change direction in a controllable manner while moving. A bracket 13 is installed on the upper side of the vehicle body 11, and a sealing plate is fixed around the bracket 13. A water pump, a high-pressure pump assembly 15 and a cache water tank 16 are installed in the inner cavity of the bracket 13. The water pump draws the accumulated water in the river channel into the cache water tank 16 through a pipeline. The high-pressure pump assembly 15 is located on the upper side of the cache water tank 16. The high-pressure pump assembly 15 is used to supply water to the high-pressure nozzle. A connected fixing frame 14 is fixed on the upper front side of the bracket 13, such as Figure 2 shown.

[0034] The folding frame 2 includes a fixed shaft 21, a shaft sleeve 22 and a rotating frame 23, wherein Figure 2As shown, fixed shafts 21 are vertically installed on both sides of the conjoined fixing frame 14, and shaft sleeves are fixed on the inner sides of the two rotating frames 23 on both sides of the conjoined fixing frame 14, and the shaft sleeves 22 on both sides are respectively fitted on the outer sides of the corresponding fixed shafts 21. Therefore, the rotating frames 23 on both sides can rotate along their fixed shafts 21 respectively, and the two states of rotation are respectively as shown in FIG. Figure 2 and Figure 3 shown.

[0035] The composite track 3 includes an upper track 31, a lower track 32, a slot 33, a connecting plate 34, a fixing bolt 35 and a plug 36, wherein Figure 2 As shown, both the upper rail 31 and the lower rail 32 are C-shaped structures, each consisting of a web and two side flanges. The webs of the upper rail 31 and lower rail 32 are fixed together, with gaps between adjacent webs. Connecting plates 34 with mounting holes are fixed to each end of the composite rail 3. The gap between the webs at one end of the composite rail forms a slot 33, while a plug 36 is fixed to the gap at the other end. When docking multiple composite rails, the plugs of adjacent composite rails fit into the slots and are secured with fixing bolts 35. The connecting plates 34 of adjacent composite rails are also bolted together.

[0036] like Figure 2 and Figure 3 As shown, a pair of composite rails at the root are fixed to the rotating frames 23 on both sides, specifically, the composite rails are fixed to the outer sides of the corresponding rotating frames. In the non-working state, only the two composite rails at the root are fixed to the two rotating frames 23, so that the two composite rails at the root can rotate with the rotating frames 23 on both sides. Figure 2 The expanded state shown or Figure 3 In the folded state shown, the root composite rails on both sides are parallel to the vehicle body 11 and are located on both sides of the vehicle body 11.

[0037] like Figure 1 As shown, in the working state, multiple composite tracks are sequentially tail-jointed and fixedly connected to the root composite track to form a combined composite track. It is best to ensure that the combined tracks on both sides of the vehicle body 11 are symmetrical.

[0038] Furthermore, an auxiliary support mechanism 4 may be installed at the outermost end of the composite track.

[0039] like Figure 6As shown, one form of auxiliary support mechanism 4 includes a vertical sleeve 41, telescopic legs 42, a lower wheel seat 43, running wheels 44, side sleeves 45, side frames 46, side wheel seats 47, and side wheels 48. The inner side of the vertical sleeve 41 is fixed to the end of the composite track. The telescopic legs 42 are mounted within the lower end of the vertical sleeve 41. The lower wheel seat 43 is fixed to the lower end of the telescopic legs 42, and the bottom of the lower wheel seat 43 is mounted with running wheels 44. Alternatively, a side sleeve 45 is vertically fixed to the outer side of the vertical sleeve 41. The side frame 46 is mounted within the side sleeve 45. The end of the side frame 46 is fixed to the side wheel seat 47, and the side wheel seat 47 is mounted on the side wheel seat 47. The running wheels 44 are used to support the riverbed or the river bank slope, and the side wheels 48 are used to support the river bank slope and maintain the horizontality of the composite track on both sides. In other words, the side wheels on both sides are supported on the surface of the river bank slope to ensure that the composite track remains horizontal and prevents tilting.

[0040] On the basis of the composite track of the above combination, a sludge treatment unit 5 is installed at the bottom of the composite track, and a collection and transfer unit 6 is installed at the top of the composite track.

[0041] like Figure 1 As shown, the sludge treatment unit 5 includes a sludge pump 51, a suction pipe 52, and an output pipe 53. The suction port of the sludge pump 51 is connected to the suction pipe 52, which extends into the deep layer of sludge. The outlet of the sludge pump is connected to the output pipe 53, and the outlet of the output pipe 53 is discharged to the collection and transfer unit 6. The sludge treatment unit 5 also includes an auxiliary support rod on the side, and the output pipe 53 is fixed on the upper side of the auxiliary support rod.

[0042] like Figure 1 As shown, the collection and transfer unit 6 includes a support bucket (such as the bucket cover component 562) and a mud receiving lining bucket 61. The mud receiving lining bucket 61 is mounted inside the support bucket. When the collection and transfer unit 6 is full and transported to the end of the composite track, the mud receiving lining bucket 61 is removed by a lifting mechanism and replaced with an empty mud receiving lining bucket 61. A turning frame can also be provided at the end of the collection and transfer unit 6. When the collection and transfer unit 6 moves to the end of the composite track, it hits the turning frame, causing the collection and transfer unit 6 to turn over as a whole and discharge the sludge to an external mud receiving unit.

[0043] The sludge treatment unit 5 and the collection and transfer unit 6, or one of them, includes a rail car 56. Figure 5 As shown, it includes a bottom plate 561, a bucket cover component 562, a wheel frame 563, and a track wheel 564, wherein,

[0044] A bucket cover component 562 is fixed to the upper side of the bottom plate 561, and a wheel frame 563 is fixed to the lower periphery of the bottom plate 561. A front axle is installed between the front pair of wheel frames 563, and a rear axle is installed between the rear pair of wheel frames 563. Track wheels 564 are installed at both ends of the front and rear axles. A drive motor 565, a transmission mechanism 566, and a power module 567 are installed at the bottom of the bottom plate 561 in sequence. The drive motor 565 drives the front axle or the rear axle to rotate through the transmission mechanism 566, thereby driving the rail vehicle to move. Figure 9 As shown, each track wheel 564 is respectively mounted between the two side wings of the composite track, allowing the rail car 56 to travel along the composite track without derailing, and also allowing the rail car to travel not only along the upper side of the composite track but also along the lower side of the composite track. A power module 567 is installed below the base plate 561. The power module 567 can be an independent battery, an external power source, or a power source drawn from the vehicle body. The transmission mechanism includes a gearbox, the input shaft of which is connected to the motor shaft, and a worm is installed at the end of the output shaft of the gearbox. The worm is installed in a worm rack, and a worm wheel is installed in the middle of the front wheel shaft or the rear wheel shaft, and the worm and worm wheel are meshed.

[0045] Furthermore, a high-pressure cutting unit 7 is installed inside the sludge processing unit 5 for cutting and crushing the sludge.

[0046] A form of high pressure cutting unit 7 such as Figure 8 As shown, it includes a central fixed frame 71, parallel connecting rods 72, a base 73, a high-pressure nozzle 74, a cylinder 75 and a high-pressure water supply pipe 76. Among them, the central fixed frame 71 is vertically fixed to the middle part of the bucket cover part 562 of the sludge treatment unit 5. The upper and lower ends of the central fixed frame 71 are respectively provided with axial holes, and the upper and lower ends of the base 73 are also provided with axial holes. The upper axial holes of the central fixed frame 71 and the base 73 are hinged together through the upper connecting rod, and the lower axial holes of the central fixed frame 71 and the base 73 are hinged together through the lower connecting rod. The upper and lower connecting rods are a pair of parallel connecting rods 72, and the central fixed frame 71 is parallel to the base 73, that is, the base 73 is always in a vertical state. A high-pressure nozzle 74 is fixed on the base 73, and the high-pressure nozzle 74 is connected to the high-pressure water supply pipe 76. The high-pressure water supply pipe 76 is connected to the output end of the high-pressure pump assembly 15. The cylinder 75 is hinged between the inner cavity of the bucket cover part 562 and the upper connecting rod. When the cylinder 75 is controlled by the controller to frequently extend and retract, it can drive the high-pressure nozzle 74 to move left and right, but the high-pressure nozzle 74 is always in a vertical downward state.

[0047] The above embodiment includes the following process when applied:

[0048] Here’s how to use it:

[0049] 1. Preparation: Deploy the river desilting equipment for water conservancy construction to the river channel requiring desilting. Ensure that the equipment's locomotive mechanism, folding frame, composite track, and auxiliary support mechanisms are fully installed and in working order. Ensure the equipment is receiving power or connected to an external power source.

[0050] 2. Start the device: Start the locomotive mechanism 1 and control the vehicle's movement and steering through the remote control. The crawler tracks 12 of the locomotive mechanism firmly fix the vehicle on the ground, allowing it to move and work stably.

[0051] 3. Unfolding the composite track: In the non-operating state, only the two root composite tracks are fixed to the turntable 23, allowing the composite tracks to rotate with the turntable 23.
