Description

Technical Field

[0001] This invention relates to the field of dredging equipment technology, and in particular to an integrated dredging vehicle. Background Technology

[0002] Dredging is an important engineering method for maintaining water quality, ensuring flood control safety, and improving the ecological environment. With technological advancements, integrated dredging vehicles, which combine a chassis, dredging pump, and mud-water separator, are widely used due to their high mobility and efficiency. These vehicles typically use the negative pressure generated by the dredging pump to draw a mud-water mixture containing solid particles from the bottom of the water through a dredging pipe to the onboard separation equipment for treatment.

[0003] However, in actual operation, the above-mentioned dredging method based on negative pressure suction has a significant technical challenge: under strong negative pressure, large solid particles such as stones, bricks, and woven bags in the mud-water mixture are easily sucked into the dredging pump. These large particles not only impact and wear down key internal components of the pump, such as the impeller, shortening the equipment's service life, but in severe cases, they can even directly cause the pump to seize or be damaged, resulting in operation interruption and high maintenance costs.

[0004] To address this issue, the common technical approach in existing technologies is to install a filter device, such as a protective cover or filter basket with a fixed filter screen, at the front end of the dredging pipe (i.e., the water inlet). The main function of this filter device is to physically intercept large particles of impurities before they enter the dredging pump. While this method mitigates the risk of direct damage to the pump body to some extent, it introduces new and more challenging operation and maintenance problems. During prolonged continuous negative pressure adsorption operations, the intercepted solid particles quickly accumulate on the filter screen surface, tightly adhering to and clogging the filter pores. Once the filter screen is clogged, it drastically reduces suction efficiency and flow rate, making dredging operations ineffective. At this point, the machine must be stopped, and manual labor is required to lift the filter device to the water surface or land for manual cleaning to remove the deposits. This process is not only labor-intensive and poses safety hazards, but the frequent shutdowns for cleaning severely impact the continuity and efficiency of the entire dredging operation, becoming a key bottleneck restricting the efficient and automated operation of integrated dredging vehicles. Summary of the Invention

[0005] This invention provides an integrated dredging vehicle that can solve the following problems existing in the prior art: During prolonged continuous negative pressure adsorption operations, intercepted solid particulate impurities quickly accumulate on the filter screen surface, tightly adhering to and clogging the filter pores. Once the filter screen is clogged, it drastically reduces suction efficiency and flow rate, making dredging operations ineffective.

[0009] Preferably, a sludge-removing plate is slidably embedded in the filter cylinder, and the sludge-removing plate divides the inside of the filter cylinder into a first sludge-removing chamber and a second sludge-removing chamber. The first sludge-removing chamber is provided with a first sludge-removing part for pumping out the mud and water in the chamber, and the second sludge-removing chamber is provided with a second sludge-removing part for pumping out the mud and water in the chamber. The first sludge removal chamber is provided with a first adjustment part for adjusting the opening or closing of the filter holes on the side wall of the chamber, and the second sludge removal chamber is provided with a second adjustment part for adjusting the opening or closing of the filter holes on the side wall of the chamber.

[0010] Preferably, the first dredging part includes a first dredging pipe fixed to the dredging plate, the end of the first dredging pipe away from the dredging plate slidingly through the filter cylinder and connected to the conveying pipe, and the second dredging part includes a second dredging pipe fixed to the other side of the dredging plate, the first dredging pipe and the second dredging pipe being connected and having the same axial length; The first and second sludge-dredging pipes have several sets of sludge-dredging holes evenly distributed on their pipe walls.

[0011] Preferably, a first sealing sleeve is slidably sleeved on the first dredging pipe, and a second sealing sleeve is slidably sleeved on the second dredging pipe. The first sealing sleeve and the second sealing sleeve are respectively provided with a plurality of sets of adsorption holes corresponding to the dredging holes. The first sealing sleeve and the second sealing sleeve are respectively connected to the driving part that drives them to slide along the dredging pipe body.

[0012] Preferably, the first adjustment part includes a first annular baffle fixed to the sludge removal plate, the outer edge of the first annular baffle slidingly fitting against the inner wall of the filter cylinder; the second adjustment part includes a second annular baffle fixed to the other side of the sludge removal plate, the outer edge of the second annular baffle slidingly fitting against the inner wall of the filter cylinder; the axial length of both the first annular baffle and the second annular baffle is one-third of the axial length inside the filter cylinder. The cleaning module also includes a lifting unit, which is used to drive the filter cartridge to move up and down axially.

[0013] Preferably, the lifting unit includes a mounting plate fixed to one side of the vehicle body, and a lifting electric cylinder is fixedly arranged on the mounting plate. The drive end of the lifting electric cylinder is fixedly connected to the filter cylinder.

[0014] Preferably, an upper scraper ring and a lower scraper ring are respectively sleeved on the outer side of the filter cylinder, and the cylinder wall of the filter cylinder slides and fits against the inner edge of the upper scraper ring and the lower scraper ring.

[0015] Preferably, the driving part includes a protruding plate fixed to the outside of the first sealing sleeve and the second sealing sleeve. The side of the protruding plate facing the sludge removal plate is fixedly connected to the limiting rod. The end of the limiting rod away from the protruding plate is slidably inserted into the limiting cylinder fixed to the sludge removal plate. The limiting cylinder is also provided with a telescopic spring.

[0016] This invention provides an integrated sludge removal vehicle, which has the following beneficial effects: 1) During the dredging process, the dredging robot of the present invention can pass through the filter holes into the cylinder after the dredging process, while large solid impurities in the dredging water are filtered out of the cylinder, thereby avoiding the phenomenon that large solid impurities in the dredging water are sucked into the conveying pipe and cause damage to the equipment. 2) In the prior art, based on the negative pressure suction effect of the dredging pump, some solid particulate impurities are adsorbed on the filter holes and cause blockage, which requires manual cleaning at regular intervals, which is very tedious. In the present invention, during the dredging process, the solid particulate impurities adsorbed on the filter holes can be cleaned in real time by the cleaning module, which can effectively avoid solid particulate impurities from clogging the filter holes, ensure the normal filtration effect of the filter cartridge, and eliminate the need for machine shutdown, further improving the dredging efficiency. 3) In this invention, the filter holes on the side wall of the second sludge removal chamber are opened by the second adjusting part, and the filter holes on the side wall of the first sludge removal chamber are closed by the first adjusting part. Then, the first sludge removal part is started to extract the mud and water in the first sludge removal chamber. During the extraction process, since the filter holes on the side wall of the first sludge removal chamber are closed, the first sludge removal part will not generate a continuous negative pressure adsorption effect in the first sludge removal chamber. This can prevent solid particle impurities on the outside of the filter cylinder from clogging the filter holes under long-term negative pressure adsorption. Correspondingly, after the mud and water in the first sludge removal chamber is extracted, the filter holes on the side wall of the first sludge removal chamber are opened by the first adjusting part. The first sludge chamber is opened, allowing mud and water to enter the chamber through the filter holes on the side wall of the first sludge chamber. The second adjustment unit adjusts the filter holes on the side wall of the second sludge chamber to close. The second sludge chamber then extracts the mud and water from the second sludge chamber. This process is repeated to achieve the effect of alternating extraction of mud and water from the first and second sludge chambers. The two chambers are independent of each other, so that while one set of chambers is extracting mud and water, the other set of chambers can store mud and water. During the storage of mud and water, the mud and water enter the chamber in a natural flow state, rather than under continuous negative pressure adsorption. This avoids some solid particles and impurities from getting stuck in the filter holes and becoming difficult to clean. Attached Figure Description

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Example 1

[0021] like Figures 1 to 5 The present invention provides an integrated dredging vehicle, including a dredging vehicle body 1, a dredging robot 4 inside the dredging vehicle body 1, and a dredging module on the dredging robot 4, which is used to adsorb and transport the mud-water mixture. In this embodiment, the dredging module is connected to the dredging pump 301 fixedly installed on the dredging vehicle body 1 via the delivery pipe 202. Specifically, this embodiment sets up a dredging robot 4 on the dredging vehicle body 1. The dredging robot 4 is small in size, so as to move the dredging module to a specific dredging scene for dredging, and has a wider range of applications. During the dredging process, the dredging pump 301 can be started. The dredging pump 301 extracts the mud and water mixture from the dredging module through the delivery pipe 202 and proceeds to the next process.

[0022] The dredging vehicle body 1 is also equipped with a mud-water separator 2. The other end of the dredging pump 301 is connected to the mud-water separator 2. The mud-water separator 2 is used to separate the pumped mud and water. It should be noted that after the dredging pump 301 in this embodiment pumps out the mud and water, it can be separated by the mud-water separator 2. It should be noted that the existing technology can be used for the dredging pump 301 and the mud-water separator 2 in this embodiment. This embodiment does not limit their specific models and structures, as long as they meet the actual application requirements.

[0023] As a further embodiment, the dredging robot 4 includes a walking vehicle 401, on which a positioning bracket 402 for fixing the conveying pipe 202 is provided; wherein, a filter cylinder 6 is provided at the front of the walking vehicle 401, and the end of the conveying pipe 202 passes through the filter cylinder 6, and the filter cylinder 6 is evenly provided with filter holes 601 for filtering solid impurities in the mud and water; it can be explained that, during the dredging process, the dredging robot 4 of this embodiment can pass through the filter holes 601 into the cylinder after filtration, while large solid impurities in the mud and water are filtered out of the cylinder, thereby avoiding the phenomenon that large solid impurities in the mud and water are sucked into the conveying pipe 202 and cause damage to the equipment; Furthermore, the dredging module also includes a cleaning module, which is used to treat solid particles that are blocked in the filter holes 601. It should also be noted that in the prior art, based on the negative pressure suction effect of the dredging pump 301, some solid particles and impurities are adsorbed onto the filter holes 601, causing blockage. This requires manual cleaning at regular intervals, which is very tedious. However, in this embodiment, during the dredging process, the cleaning module can clean the solid particles and impurities adsorbed at the filter holes 601 in real time, which can effectively prevent solid particles and impurities from clogging the filter holes 601, ensuring the normal filtration effect of the filter cartridge 6, and eliminating the need for shutdown, thus further improving the dredging efficiency.

[0024] As one implementation method of this embodiment, in order to facilitate the deployment of the dredging robot 4, the dredging vehicle body 1 is also equipped with a hoisting mechanism 5 for hoisting and deploying the dredging robot 4. It should be noted that since the dredging robot 4 is placed at a certain height on the dredging vehicle body 1, when the dredging vehicle body 1 moves to the position to be dredged, the hoisting mechanism 5 can be used to transfer the dredging robot 4 to the predetermined dredging position for dredging. After the dredging is completed, the hoisting mechanism 5 will transfer the dredging robot 4 back to the dredging vehicle body 1, thereby achieving the effect of automatic loading and unloading of the dredging robot 4. This embodiment does not require manual movement of the dredging robot 4, and has a higher degree of automation. As another implementation method, for facilitating the conveying of the conveying pipe 202, please refer to... Figures 1-2 The dredging vehicle body 1 is equipped with a hydraulic hose reel 3 for retracting and extending the delivery pipe 202; specifically, in this embodiment, the hydraulic hose reel 3 can automatically retract and extend the delivery pipe 202 based on the position of the dredging robot 4, further improving the degree of automation.

[0025] Example 2

[0026] Based on Example 1, please refer to Figures 3-8A sludge-removing plate 7 is slidably embedded in the filter cylinder 6, dividing the interior of the filter cylinder 6 into a first sludge-removing chamber 604 and a second sludge-removing chamber 605. The first sludge-removing chamber 604 is provided with a first sludge-removing part for pumping out the mud and water in the chamber, and the second sludge-removing chamber 605 is provided with a second sludge-removing part for pumping out the mud and water in the chamber. The first sludge-removing chamber 604 is also provided with a first adjusting part for adjusting the opening or closing of the filter holes 601 on the side wall of the chamber, and the second sludge-removing chamber 605 is provided with a second adjusting part for adjusting the opening or closing of the filter holes 601 on the side wall of the chamber. It can be noted that in this embodiment, by dividing the filter cylinder 6 into two sets of sludge-removing chambers, and each set of sludge-removing chambers is provided with independent sludge-removing parts, in actual application, the mud and water outside the filter cylinder 6 can enter the first sludge-removing chamber 604 and the second sludge-removing chamber 605 respectively through the filter holes 601. During dredging, the filter holes 601 on the side wall of the second dredging chamber 605 are first opened by adjusting the second adjusting unit, and the filter holes 601 on the side wall of the first dredging chamber 604 are closed by adjusting the first adjusting unit. Then, the first dredging unit is activated to extract the mud and water in the first dredging chamber 604. During the extraction process, since the filter holes 601 on the side wall of the first dredging chamber 604 are closed, the first dredging unit will not generate a continuous negative pressure adsorption effect in the first dredging chamber 604. This avoids solid particle impurities on the outside of the filter cylinder 6 from clogging the filter holes 601 under long-term negative pressure adsorption. Correspondingly, after the mud and water in the first dredging chamber 604 are extracted, the filter holes 601 on the side wall of the first dredging chamber 604 are closed by adjusting the first adjusting unit. The filter hole 601 is opened, allowing mud and water to enter the cavity through the filter hole 601 on the side wall of the first sludge removal cavity 604. The second adjustment unit adjusts the filter hole 601 on the side wall of the second sludge removal cavity 605 to close. The second sludge removal unit extracts the mud and water in the second sludge removal cavity 605. This process is repeated to achieve the effect of alternating extraction of mud and water from the first sludge removal cavity 604 and the second sludge removal cavity 605. The two are independent of each other, so that while one set of cavities is extracting mud and water, the other set of cavities can store mud and water. During the storage of mud and water, the mud and water enter the cavity in a natural flow state, rather than under continuous negative pressure adsorption. This can prevent some solid particulate impurities from getting stuck in the filter hole 601 and becoming difficult to clean.

[0027] As one embodiment of this invention, the first dredging section includes a first dredging pipe 203 fixed on the dredging plate 7. The end of the first dredging pipe 203 away from the dredging plate 7 slides through the filter cylinder 6 and is connected to the conveying pipe 202. The second dredging section includes a second dredging pipe 201 fixed on the other side of the dredging plate 7. The first dredging pipe 203 and the second dredging pipe 201 are connected and have the same axial length. A plurality of dredging holes 204 are evenly opened on the pipe walls of the first dredging pipe 203 and the second dredging pipe 201. It can be noted that when the mud and water in the first dredging chamber 604 or the second dredging chamber 605 are extracted in this embodiment, they can be extracted through the dredging pipes provided in the corresponding chambers. The mud and water can pass through the dredging holes 204 and enter the pipe. Specifically, a first sealing sleeve 703 is slidably fitted onto the first dredging pipe 203, and a second sealing sleeve 704 is slidably fitted onto the second dredging pipe 201. The first sealing sleeve 703 and the second sealing sleeve 704 each have several sets of suction holes 705 corresponding to the dredging holes 204. The first sealing sleeve 703 and the second sealing sleeve 704 are respectively connected to a driving part that drives them to slide along the dredging pipe body. It can be noted that, initially, the suction holes 705 on the first sealing sleeve 703 are misaligned with the dredging holes 204 on the first dredging pipe 203, and the suction holes 705 on the second sealing sleeve 704 are misaligned with the dredging holes 204 on the second dredging pipe 201. Therefore, the first dredging chamber 604 and the second... The mud and water in the dredging chamber 605 will not pass through the adsorption hole 705 and the dredging hole 204 to enter the pipe. In the actual dredging process, when it is necessary to adjust the first dredging pipe 203 to extract the mud and water in the first dredging chamber 604, the first sealing sleeve 703 can be driven to slide on the first dredging pipe 203 by the driving part, so that the adsorption hole 705 on the first sealing sleeve 703 corresponds to the dredging hole 204 on the first dredging pipe 203. When the dredging pump 301 is started, the mud and water in the first dredging chamber 604 can be sucked into the first dredging pipe 203 in sequence through the adsorption hole 705 and the dredging hole 204 under negative pressure. Correspondingly, the mud and water in the second dredging chamber 605 can be extracted in the same way. This embodiment will not elaborate on this.

[0028] In this embodiment, please refer to Figures 5-8The first adjustment part includes a first annular baffle 701 fixed on the sludge removal plate 7, the outer edge of the first annular baffle 701 slidingly fitting against the inner wall of the filter cylinder 6. The second adjustment part includes a second annular baffle 702 fixed on the other side of the sludge removal plate 7, the outer edge of the second annular baffle 702 slidingly fitting against the inner wall of the filter cylinder 6. The axial length of both the first annular baffle 701 and the second annular baffle 702 is one-third of the axial length inside the filter cylinder 6. The cleaning module also includes a lifting part, which is used to drive the filter cylinder 6 to move up and down axially. It can be noted that when the mud and water in the first sludge removal chamber 604 need to be extracted in this embodiment, the lifting part can be used to adjust the lifting of the filter cylinder 6 so that the end of the first annular baffle 701 away from the sludge removal plate 7 abuts against the top of the filter cylinder 6, so that the sludge removal plate 7, the first annular baffle 701 and the top wall of the filter cylinder 6 enclose a sealed cavity. Based on this, the mud and water in the sealed cavity can be extracted through the first sludge removal pipe 203. Accordingly, when the mud and water in the second sludge removal chamber 605 are extracted, the end of the second annular baffle 702 away from the sludge removal plate 7 can be adjusted by the lifting part to abut against the bottom of the filter cylinder 6 to form a sealed chamber again, and the mud and water in the sealed chamber can be extracted through the second sludge removal pipe 201. Therefore, in this embodiment, when extracting mud and water from different dredging chambers, it is only necessary to adjust the lifting of the filter cylinder 6 by means of the lifting part; It should also be noted that when the sludge removal plate 7 moves toward any side of the sludge removal chamber, the volume of the sludge removal chamber is compressed, causing some of the mud and water initially immersed in the sludge removal chamber to be pushed out in the opposite direction along the filter hole 601 to the outside of the filter cylinder 6, thereby achieving the effect of backflushing the filter hole 601, so as to automatically flush out the solid impurity particles blocked in the filter hole 601, and thus simultaneously achieve the effect of automatically cleaning the solid particle impurities in the filter hole 601.

[0029] Specifically, the lifting unit in this embodiment includes a mounting plate 607 fixed to one side of the vehicle body 401. A lifting cylinder 606 is fixedly arranged on the mounting plate 607. The driving end of the lifting cylinder 606 is fixedly connected to the filter cartridge 6. It can be understood that in this embodiment, by activating the lifting cylinder 606, the lifting cylinder 606 can synchronously drive the filter cartridge 6 to rise and fall.

[0030] During the backflushing process of the filter hole 601, in order to prevent solid particles from adhering to the outer wall of the filter cylinder 6, an upper scraper ring 603 and a lower scraper ring 602 are respectively fitted on the outer side of the filter cylinder 6. The cylinder wall of the filter cylinder 6 slides and fits against the inner edge of the upper scraper ring 603 and the lower scraper ring 602. It can be explained that during the process of the lifting cylinder 6 being driven to rise and fall by the lifting cylinder 606, the impurities adhering to the outer wall of the filter cylinder 6 can be scraped off by the cooperation of the upper scraper ring 603 and the lower scraper ring 602.

[0031] As one implementation method of this embodiment, please refer to Figures 7-8 The driving unit includes a protruding plate 706 fixed to the outside of the first sealing sleeve 703 and the second sealing sleeve 704. The side of the protruding plate 706 facing the sludge removal plate 7 is fixedly connected to the limiting rod 707. The end of the limiting rod 707 away from the protruding plate 706 is slidably inserted into the limiting cylinder 709 fixed on the sludge removal plate 7. The limiting cylinder 709 is also provided with a telescopic spring 708. One end of the telescopic spring 708 is fixed to the bottom of the cylinder, and the other end is fixed to the limiting rod 707. It can be explained that when the adsorption hole 705 on the sealing sleeve and the sludge removal hole 204 on the sludge removal pipe are in a misaligned sealing state, as the lifting unit drives the filter cylinder 6 to rise and fall, the sealing sleeve first abuts against the bottom or top of the filter cylinder 6. Under the abutment action, as the filter cylinder 6 continues to move, the filter cylinder 6 can press the sealing sleeve to move towards the sludge removal plate 7, thereby compressing the telescopic spring 708 and generating elastic force. Correspondingly, as the filter cylinder 6 moves in the opposite direction, the telescopic spring 708 can drive the sealing sleeve to reset.

[0032] A dredging method using an integrated dredging vehicle includes the following steps: Please see Figures 1-5 S1, the dredging vehicle 1 moves to the dredging location, and the hoisting mechanism 5 transfers the dredging robot 4 to the predetermined dredging location for dredging; S2, the hydraulic hose reel 3 automatically retracts and extends the conveying pipe 202 based on the position of the dredging robot 4; S3. During the dredging process, the dredging pump 301 is started, and the dredging pump 301 extracts the mud-water mixture from the dredging module through the delivery pipe 202. S4, the dredging robot 4, during the dredging process, the filtered mud and water can pass through the filter hole 601 and enter the cylinder, while large particles of solid impurities in the mud and water are filtered out of the cylinder. S5. The cleaning module cleans the solid particulate impurities adsorbed at the filter hole 601. S6. After the dredging pump 301 pumps out the mud and water, it is separated into mud and water by the mud and water separator 2. S7. After the dredging is completed, the hoisting mechanism 5 will transfer the dredging robot 4 to the dredging vehicle body 1.

[0033] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
