Description

Technical Field

[0001] This utility model belongs to the field of silt removal technology, and more specifically, it relates to a silt removal device that is easy to move underwater. Background Technology

[0002] After a long period of operation, a large amount of silt will gradually accumulate at the bottom of the irrigation canals. When the amount of silt accumulates to a certain level, it may cause blockage of the canals, affecting the smooth flow of water. At the same time, the accumulation of silt can also cause abnormal rise in the water level of the canals, increasing the risk of water overflow and posing a potential threat to the surrounding environment and facilities. Therefore, in order to ensure the normal operation of the irrigation canals and the safety of the surrounding area, we need to clean and maintain the silt at the bottom of the canals regularly.

[0003] Existing similar underwater sludge removal devices often rely on a single propulsion method, such as water flow or external force, and lack an active and flexible movement mechanism, which limits the device's movement efficiency in the underwater environment. During the sludge removal process, it is difficult to maintain a stable contact state between the scraper and the bottom of the waterway, which can easily affect the cleaning effect. Furthermore, after long-term use or after being hit by a collision, the scraper is cumbersome to disassemble and replace, making maintenance inconvenient. Utility Model Content

[0011] In at least some embodiments, a set of first elastic members are respectively sleeved on the support rods at the front and rear ends of the mounting frame, and the top of the first elastic members is in contact with the bottom surface of the connecting plate on the cleaning chamber.

[0012] In at least some embodiments, a set of second elastic members are respectively sleeved on the slide rod at the outer end of the insertion rod, and the outer ends of the second elastic members are respectively in contact with the inner end face of the fixing plate on the mounting bracket.

[0013] In at least some embodiments, a set of first gears is fixedly installed at the inner end of the drive propeller, and a set of second gears is fixedly installed at both ends of the rotating scraper plate, and the second gears at both ends of the rotating scraper plate are respectively meshed and connected to the first gears at the inner end of the drive propeller.

[0014] Compared with the prior art, the silt cleaning device of this utility model that is easy to move underwater has the following beneficial effects:

[0015] 1. The combination of the drive propeller and scraper facilitates the rotation of the drive propeller via a motor, thereby assisting in the movement of the underwater device. The support rods at the front and rear ends of the mounting frame are slidably mounted on the sliding holes of the connecting plates at the front and rear ends of the cleaning chamber. With the cooperation of the first elastic element on the support rod, the outer end of the scraper has an inclined structure, ensuring that the scraper on the mounting frame is always in contact with the bottom of the waterway. This allows the device to easily scrape away the silt at the bottom of the waterway. Furthermore, the second gears at both ends of the rotating scraper blade are meshed with the first gear at the inner end of the drive propeller, enabling the rotating scraper blade to rotate clockwise. This allows the silt to be discharged through the external pipe on the collection chamber via the suction pump, effectively improving the silt cleaning effect of the device.

[0016] 2. The scraper is designed so that it can be slidably installed on the sliding holes of the fixing plates at both ends of the mounting frame via the sliding rod at the outer end of the insertion rod. Pulling the insertion rod outward will insert the positioning block at the inner end of the scraper into the positioning groove of the mounting frame. After the scraper moves to the fixed position, the insertion rod is released. Under the action of the second elastic element on the sliding rod, the insertion rods at both ends of the mounting frame are inserted into the insertion holes at both ends of the scraper. This makes the scraper of this device easy to disassemble and replace quickly after long-term use or collision. Attached Figure Description

Pulling the insert rod 204 outward will insert the positioning block 301 at the inner end of the scraper 3 into the positioning groove 203 of the mounting frame 2. After the scraper 3 moves to the fixed position, the insert rod 204 is released. Under the action of the second elastic element 2042 on the slide rod 2041, the insert rods 204 at both ends of the mounting frame 2 are respectively inserted into the insertion holes 302 at both ends of the scraper 3, so that the scraper 3 of this device can be quickly disassembled and replaced after long-term use or collision.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In use, the motor 103 drives the drive propeller 4 to rotate, assisting in the movement of the underwater device.
