Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of culvert cleaning, and particularly relates to a tubular culvert dredging structure. Background Art
[0002] A culvert refers to a water passage built below the road surface in highway or railway engineering construction so that the highway or railway can pass through the water channel smoothly. Through this structure, water can flow under the highway or railway, which is used to cross natural valleys and depressions to drain floods, or as a water channel for farmland irrigation. Many culverts are directly built with some circular pipes. After long-term use, a large amount of silt will accumulate in the culvert. If not cleaned, it will cause water flow blockage. Therefore, it is necessary to regularly clean and dredge the culvert.
[0003] However, for the existing tubular culverts at present, it is often impossible for personnel to enter during cleaning. Therefore, some dredging equipment needs to be used. However, most of these dredging equipment rely on manual pulling for cleaning. It is very difficult to ensure uniform contact between the dredging equipment and the inner wall of the culvert during cleaning, and it is difficult to control the cleaning position. Therefore, the cleaning efficiency is low. Some also use a flushing device that sprays water to impact the silt in the culvert by water pressure. However, the stubborn silt adhered to the culvert is very difficult to wash down, resulting in the problem of incomplete cleaning. Summary of the Invention
[0004] In view of this, the present invention provides a tubular culvert dredging structure to solve the problems of low cleaning efficiency and incomplete cleaning of the existing culvert dredging equipment.
[0005] The present invention provides a tubular culvert dredging structure, which specifically includes: a main support frame; a main shaft is rotatably installed on the front and rear sides of the main support frame, and a bevel gear is arranged on the outer side of each of the two main shafts; a waterproof double-shaft motor is fixedly installed at the middle position of the main support frame, and the front and rear ends of the waterproof double-shaft motor are respectively fixedly connected to the two main shafts; four groups of transmission shafts are rotatably installed on the outer side of the main support frame, and a bevel gear is arranged at both ends of each transmission shaft; the other ends of the four groups of transmission shafts are respectively rotatably connected to four roller support frames; an electric cylinder is fixedly installed on the outer side of the main support frame; the other ends of the four electric cylinders are respectively fixedly connected to one side of the four roller support frames; a roller shaft is rotatably installed on the front and rear sides of the four roller support frames, and a bevel gear is fixedly arranged on each roller shaft; rollers are fixedly arranged at both ends of each roller shaft; four groups of a total of eight cleaning frame support cylinders are fixedly arranged on the outer side of the front end of one of the main shafts; four groups of a total of eight cleaning frame support rods are slidably installed at one end of the eight cleaning frame support cylinders; the other ends of the four groups of cleaning frame support rods are fixedly connected to a cleaning frame; a spring is arranged on the outer sides of the cleaning frame support cylinders and the cleaning frame support rods.
[0006] Further, the main support frame is in a cross-shaped structure as a whole, and the four groups of transmission shafts on the outside of the main support frame are also arranged in a cross shape.
[0007] Further, two rectangular bumps are arranged on the outer sides of one ends of the cleaning frame support rods connected to the cleaning frame support cylinders, and two strip-shaped grooves corresponding to their widths are also arranged on the outer sides of the cleaning frame support cylinders. The cleaning frame support rods can slide under the support of the cleaning frame support cylinders.
[0008] Further, the bevel gears at one ends of the transmission shafts are engaged with the bevel gears on the main shaft, and the bevel gears at the other ends of the transmission shafts are engaged with the bevel gears on the roller shafts.
[0009] Further, an annular plate is fixedly arranged on the outer sides of the cleaning frame support cylinders, and the springs are located on the outer sides of the cleaning frame support cylinders and the cleaning frame support rods, between the annular plate and the cleaning frame.

[0012] Further, four strip-shaped protrusions are arranged on the outer sides of the thin round rods of the transmission shafts, and four corresponding strip-shaped guide grooves are arranged on the outer sides of the cylindrical holes at one ends of the thick round rods of the transmission shafts.
[0013] Beneficial Effects
[0014] 1. The cleaning frame in the present invention can be adjusted to closely adhere to the inner walls of tubular culverts of different specifications. When the main shaft rotates, it can drive the cleaning frame support cylinder and the cleaning frame support rod to rotate.

[0030] Embodiment: Please refer to Figures 1 to 8 as shown:
[0031] The present invention provides a tubular culvert dredging structure, including a main support frame 1; a main shaft 2 is rotatably installed on both the front and rear sides of the main support frame 1, and a bevel gear 6 is arranged on the outer side of each of the two main shafts 2. The main support frame 1 is used to support the waterproof double-shaft motor 3 and the main shaft 2. When the main shaft 2 rotates, it can drive the cleaning frame 12 to rotate to clean the inner wall of the culvert, so that the silt adhered to the culvert can be scraped off. Moreover, when the main shaft 2 rotates, it can also drive the transmission shaft 4 to rotate synchronously through the bevel gear 6; the main support frame 1 is of a cross-shaped structure as a whole, and the four groups of transmission shafts 4 on the outer side of the main support frame 1 are also arranged in a cross shape. Therefore, when installing this device, it can be stably supported by the four groups of rollers 9 evenly stressed; a waterproof double-shaft motor 3 is fixedly installed at the middle position of the main support frame 1, and the front and rear ends of the waterproof double-shaft motor 3 are respectively fixedly connected to the two main shafts 2. When the waterproof double-shaft motor 3 rotates, it can drive the main shaft 2 to rotate; four groups of transmission shafts 4 are rotatably installed on the outer side of the main support frame 1, and a bevel gear 6 is arranged at both ends of the transmission shaft 4. When the main shaft 2 rotates, it can drive the transmission shaft 4 to rotate synchronously through the bevel gear 6, and when the transmission shaft 4 rotates, it can drive the roller shaft 8 and the roller 9 to rotate synchronously through the bevel gear 6, so that this device can move in the culvert; the bevel gear 6 at one end of the transmission shaft 4 is engaged with the bevel gear 6 on the main shaft 2, and the bevel gear 6 at the other end of the transmission shaft 4 is engaged with the bevel gear 6 on the roller shaft 8. Therefore, when the main shaft 2 rotates, it can drive the transmission shaft 4 to rotate synchronously through the bevel gear 6, and when the transmission shaft 4 rotates, it can drive the roller shaft 8 and the roller 9 to rotate synchronously through the bevel gear 6, so that this device can move in the culvert; the other ends of the four groups of transmission shafts 4 are respectively rotatably connected to the four roller support frames 7. Therefore, the roller support frame 7 can support this end of the transmission shaft 4; an electric cylinder 5 is fixedly installed on the outer side of the main support frame 1. When the electric cylinder 5 expands and contracts, it can drive the roller support frame 7 to move, and then the distance between the roller support frame 7 and the main support frame 1 can be adjusted, so that this device can be placed in tubular culverts with different diameters; the other ends of the four electric cylinders 5 are respectively fixedly connected to one side of the four roller support frames 7. When the electric cylinder 5 expands and contracts, it can drive the roller support frame 7 to move, and then the distance between the roller support frame 7 and the main support frame 1 can be adjusted, so that this device can be placed in tubular culverts with different diameters; a roller shaft 8 is rotatably installed on both the front and rear sides of the four roller support frames 7, and a bevel gear 6 is fixedly arranged on the roller shaft 8. When the transmission shaft 4 rotates, it can drive the roller shaft 8 and the roller 9 to rotate synchronously through the bevel gear 6, so that this device can move in the culvert; a roller 9 is fixedly arranged at both ends of the roller shaft 8. When installing this device, the roller 9 is in close contact with the inner wall of the tubular culvert. Therefore, when the roller 9 rotates, it can drive this device to move in the culvert; eight cleaning frame support cylinders 10 in four groups are fixedly arranged on the outer side of the front end of one of the main shafts 2. The cleaning frame support cylinders 10 are used for sliding support of the cleaning frame support rods 11;One end of eight cleaning frame support cylinders 10 is slidably installed with four groups of eight cleaning frame support rods 11 in total. The cleaning frame support rods 11 are used to support the cleaning frame 12. When installing this device, the cleaning frame support rods 11 can be first pushed towards the cleaning frame support cylinders 10, and then this device is inserted into the tubular culvert, and the cleaning frame support rods 11 can be released. At this time, the spring 13 will push the cleaning frame support rods 11 to slide outwards. Therefore, the cleaning frame 12 on the cleaning frame support rods 11 can be made to closely adhere to the inner wall of the tubular culvert, and then the cleaning frame 12 can clean and dredge the silt in the tubular culvert; One end of each of the four groups of cleaning frame support rods 11 is fixedly connected with a cleaning frame 12. When the main shaft 2 drives the cleaning frame support cylinders 10 and the cleaning frame support rods 11 to rotate, it will also drive the cleaning frame 12 to rotate. At this time, the cleaning frame 12 will rotate along the inner wall of the tubular culvert. Therefore, the silt in the culvert can be scraped off, and then the silt will be washed away by the water flow, making the silt cleaning more thorough; A spring 13 is arranged on the outer sides of both the cleaning frame support cylinders 10 and the cleaning frame support rods 11. When installing this device, the cleaning frame support rods 11 can be first pushed towards the cleaning frame support cylinders 10, and then this device is inserted into the tubular culvert, and the cleaning frame support rods 11 can be released. At this time, the spring 13 will push the cleaning frame support rods 11 to slide outwards. Therefore, the cleaning frame 12 on the cleaning frame support rods 11 can be made to closely adhere to the inner wall of the tubular culvert.;
[0032] Among them, two rectangular bumps are arranged on the outer sides of the ends of the cleaning frame support rods 11 connected to the cleaning frame support cylinders 10, and two strip-shaped grooves with corresponding widths are also arranged on the outer sides of the cleaning frame support cylinders 10. The cleaning frame support rods 11 can slide under the support of the cleaning frame support cylinders 10. Therefore, when the cleaning frame support rods 11 slide under the support of the cleaning frame support cylinders 10, they are more stable, and the cleaning frame support rods 11 can be prevented from separating from the cleaning frame support cylinders 10. When installing this device, the cleaning frame support rods 11 can be first pushed towards the cleaning frame support cylinders 10, and then this device is inserted into the tubular culvert, and the cleaning frame support rods 11 can be released. At this time, the spring 13 will push the cleaning frame support rods 11 to slide outwards. Therefore, the cleaning frame 12 on the cleaning frame support rods 11 can be made to closely adhere to the inner wall of the tubular culvert, and then the cleaning frame 12 can clean and dredge the silt in the tubular culvert.
[0033] Among them, an annular plate is fixedly arranged on the outer side of the cleaning rack support cylinder 10, and the spring 13 is located outside the cleaning rack support cylinder 10 and the cleaning rack support rod 11, between the annular plate and the cleaning rack 12. When installing this device, the cleaning rack support rod 11 can be first pushed towards the cleaning rack support cylinder 10, and then this device can be inserted into the tubular culvert and the cleaning rack support rod 11 can be released. At this time, the spring 13 will push the cleaning rack support rod 11 and the cleaning rack 12 to slide towards the outside, so that the cleaning rack 12 on the cleaning rack support rod 11 can be closely attached to the inner wall of the tubular culvert, and then the cleaning rack 12 can clean and dredge the silt in the tubular culvert.
[0034] Among them, the transmission shaft 4 is evenly divided into two sections. The thin round rod is connected to the roller support frame 7, and the thick round rod is connected to the main support frame 1. And the thin round rod can slide at one end of the thick round rod. When placing this device in the culvert, first control the four electric cylinders 5 to contract synchronously, so that the roller support frames 7 can all move towards the main support frame 1 to reduce the overall outer diameter of this device. During this process, the overall length of the transmission shaft 4 will also contract. Then this device can be placed in the culvert. After placing it, control the four electric cylinders 5 to extend synchronously, so that the roller support frames 7 can all move towards the outside to increase the overall outer diameter of this device until the rollers 9 on the roller support frames 7 are closely attached to the inner wall of the culvert, and the installation is completed. During this process, the overall length of the transmission shaft 4 will also extend. Therefore, no matter how the transmission shaft 4 is adjusted, the transmission effect can be achieved.
[0035] Among them, the cleaning rack 12 is welded by thin round rods with a diameter of 2 cm. Therefore, the resistance of the cleaning rack 12 during rotation is relatively small, which is convenient for scraping and loosening the silt in the tubular culvert. Moreover, the cleaning rack 12 rotates along the inner wall of the tubular culvert, so the stubborn silt adhered to the inner wall of the culvert can also be cleaned out, and then these silts will be washed away by the water flow, making the silt cleaning more thorough and efficient.
[0036] Among them, four strip-shaped protrusions are arranged on the outer side of the thin round rod of the transmission shaft 4, and four corresponding strip-shaped guide grooves are arranged on the outer side of the cylindrical hole at one end of the thick round rod of the transmission shaft 4. Therefore, when the thick round rod of the transmission shaft 4 rotates, it can ensure that the thin round rod of the transmission shaft 4 rotates synchronously, and then it can drive the roller shaft 8 to rotate when the main shaft 2 rotates. That is, when the waterproof double-shaft motor 3 rotates, it can not only drive the cleaning rack 12 to rotate to dredge the inside of the culvert, but also drive the rollers 9 to rotate to move this device in the culvert, so as to clean different positions of the culvert.
[0037] Specific usage method and function of this embodiment: In the present invention, before using this device, first connect the waterproof double-shaft motor 3 and the four electric cylinders 5 to the external power supply line and the controller and do a good job in waterproof treatment at the joints. When it is necessary to use this device to dredge a tubular culvert, first control the four electric cylinders 5 to contract synchronously, so that the roller support frames 7 can all move towards the main support frame 1 to reduce the overall outer diameter of this device. During this process, the overall length of the transmission shaft 4 will also contract. Then, this device can be placed in the culvert. When placing it, first push the cleaning frame support rod 11 towards the cleaning frame support cylinder 10, and then this device can be inserted into the tubular culvert and the cleaning frame support rod 11 can be released. At this time, the spring 13 will push the cleaning frame support rod 11 to slide outwards, so that the cleaning frame 12 on the cleaning frame support rod 11 can be closely attached to the inner wall of the tubular culvert, and then the cleaning frame 12 can clean and dredge the silt in the tubular culvert. At this time, control the four electric cylinders 5 to extend synchronously, so that the roller support frames 7 can all move outwards to increase the overall outer diameter of this device until the rollers 9 on the roller support frames 7 are closely attached to the inner wall of the culvert, and the installation is completed. During this process, the overall length of the transmission shaft 4 will also extend. Therefore, no matter how the transmission shaft 4 is adjusted, the transmission effect can be achieved. Then, power on and start the waterproof double-shaft motor 3 through the external controller. When the waterproof double-shaft motor 3 rotates, it can drive the main shaft 2 to rotate. When the main shaft 2 rotates, it will drive the cleaning frame support cylinder 10 and the cleaning frame support rod 11 to rotate. At this time, the cleaning frame 12 will scrape off the silt in the culvert, and the cleaning frame 12 will rotate along the inner wall of the tubular culvert, so that the stubborn silt adhered to the inner wall of the culvert can also be cleaned out. Then, these silts will be washed away by the water flow, and the cleaning of the silt is more thorough. And when the main shaft 2 rotates, it will also drive the transmission shaft 4 to rotate synchronously through the bevel gear 6. When the transmission shaft 4 rotates, it can drive the roller shaft 8 and the rollers 9 to rotate synchronously through the bevel gear 6 at the other end, so that this device can continuously move in the culvert. Therefore, it can ensure that every position inside the culvert is cleaned, and this device only needs to move to the end in the culvert to complete the cleaning, and the cleaning is more efficient.
[0038] Finally, it should be noted that when the present invention describes the positions of various components and their cooperation relationships, etc., usually one / a pair of components are taken as examples. However, those skilled in the art should understand that such positions, cooperation relationships, etc. are equally applicable to other components / other pairs of components.
[0039] The above is only an exemplary implementation manner of the present invention, rather than being used to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
