Description

Technical Field

[0001] The present invention relates to the field of dredging vessels, and particularly to a multi-functional unmanned semi-submersible dredging vessel. Background Art

[0002] Currently, the existing remote control boats on the market are mostly used for model ship teaching or for putting bait, feed, etc. Although they can ensure navigation stability and speed, their towing ability is poor and they cannot drag a series of accessories such as long and thick throat pipes, suction nozzles, and counterweights to sail on the water surface. At the same time, there are generally many bubbles and flocculants on the surface of the sewage reaction tank. If a water jet engine with a strong thrust is used, the engine and the duct will be blocked by flocculants soon and cannot be used. Moreover, when the unmanned boat is operating, it is also necessary to ensure that the suction nozzle is always on the surface of the sludge and does not float in the water, otherwise it can only suck sewage and cannot adsorb sludge.

[0003] Some sewage treatment plants have tried to use excavators for dredging operations, but the effect is average. Because the radius of the sewage treatment tank is generally more than 5 meters, and the radius of some large reaction tanks exceeds 10 meters, the excavator cannot reach the central area and can only dig along the edge. At the same time, the inner surface of all sewage tanks has been treated with waterproof and anti-corrosion. If the excavator is operated improperly, it is easy to damage the waterproof layer and cause greater losses. Summary of the Invention

[0004] The main technical problem to be solved by the present invention is to provide a multi-functional unmanned semi-submersible dredging vessel, which can solve the problems in the background art.

[0005] To solve the above technical problem, a technical solution adopted by the present invention is: a multi-functional unmanned semi-submersible dredging vessel, including a hull and a remote control module. The hull is internally provided with a power module, a battery module, and an ECU control module. The power module, the battery module, and the ECU control module inside the hull are electrically connected. The front end of the hull is provided with a forward-looking radar and a signal indicator light, and the tail end is provided with a propeller. Sensors are respectively provided on both sides of the front end of the hull. There is a mud suction throat pipe inlet near the middle position of the hull, and a mud suction throat pipe penetrates and inserts. Throat pipe guide rails are provided above and below the hull at the mud suction throat pipe inlet. A synchronous ratchet is provided at the joint of the hull and the mud suction throat pipe. A gravity suction nozzle is provided at one end of the mud suction throat pipe close to the sludge, and a sewage suction pump is provided at the end far from the hull. The hull adopts a streamlined design, wider at the bottom and narrower at the top, and the throat pipe guide rail is arc-shaped.

[0006] Preferably, the gravity suction nozzle is made of metal.

[0007] Preferably, the remote control module is a 2.4GH remote control unit.

[0008] Preferably, the number of the propellers is 2.

[0009] The beneficial effects of the present invention are as follows: (1) Low cost and reusable. A multi-functional unmanned semi-submersible dredging workboat can continuously dredge a sewage tank with a radius of 6 meters and a depth of 2 meters under a pre-set program, and it only takes 7 to 8 hours to complete. During this period, only two people are needed to be on duty, which not only greatly saves labor costs, but also ensures that the dredging work can be completed without stopping the operation of the sewage treatment plant, achieving multiple benefits. Generally, when a sewage treatment plant conducts a normal dredging operation, it needs to first drain the sewage, then conduct air drying for about 24 hours to ensure the dissipation of harmful gases, and then quickly arrange personnel to enter the sewage tank for manual dredging. If the air drying time is too long, the sludge will solidify. Therefore, for a sewage tank with a radius of 6 meters and a depth of 2 meters, 6 to 8 workers are required to work simultaneously, and there are certain requirements for the operation methods of the workers to prevent damage to the waterproof layer caused by rough construction. Generally speaking, a single dredging operation requires the sewage treatment plant to stop work for at least 3 days. Calculated at 300 yuan per day for labor costs, only the labor cost alone will exceed at least 5000 yuan, not to mention other costs caused by the shutdown. (2) Due to the modular design of the present invention, the main hull is made of fiberglass, with a length of about 1.3 meters and a relatively light weight. In addition to the hull, it also includes a battery pack, a power unit, an ECU, as well as components such as a gravity suction nozzle, a sewage suction pump, and a throat pipe. It can be operated by only two people on site. When transportation is required, it can be disassembled into several parts and can be placed in the trunk of an ordinary family car, which is convenient for handling and use and can cope with various usage scenarios.

Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0014] See also Figure 1 and Figure 2 The embodiment of the present invention includes: the hull 1 adopts a semi-submersible design with a deep draft. The entire hull 1 is wide at the bottom and narrow at the top, with a very low center of gravity, thereby ensuring driving stability and being able to withstand large water flows and bubbles when working in a sewage tank. In addition, the design of the two propellers 7 being placed at the rear minimizes the impact of flocs on the hull. The hull 1 adopts a fiberglass design and is light in weight. At the same time, the mud suction operation does not require a high speed, but requires a high drag force. The semi-submersible hull ensures driving stability while taking into account high traction and drag forces.

[0015] The sewage suction pipe 10 adopts a through-type design, passing through the hull 1 from bottom to top. The hull 1 is designed with arc-shaped throat guide rails 11 on the upper and lower sides to ensure that the throat will not bend. At the same time, a synchronous ratchet 12 is installed at the junction of the hull 1 and the mud suction pipe 10. The remote control module can be set so that when a certain distance is traveled, the synchronous ratchet 12 will roll downward at the same time. At this time, the sewage suction pipe 10 continues to penetrate downward and sticks to the sludge layer. It can also be manually controlled to make the synchronous ratchet 12 rotate downward or upward to control the up and down movement of the sewage suction pipe 10.

[0016] Since the hull 1 adopts a streamlined design, the gravity suction nozzle 13 can always be closely attached to the surface of the sludge layer in a horizontal posture. At the same time, the gravity suction nozzle 13 uses a metal material with a high density and weighs about 2KG, which further stabilizes the operating state.

[0017] The technologies used in the present invention are all mature designs in the current civilian market. When in use, they can be equipped by sewage treatment stations themselves, or purchased by individuals or professional companies. A modular design is adopted according to different usage scenarios.

[0018] First, according to the pre-surveyed usage environment, preset the travel route in advance. As the hull 1 moves forward along the set route, the diving depth of the sewage suction hose 10 continuously increases. Its working principle is similar to that of a floor cleaning robot. The shape of the sewage pool is not limited and can be a circular, square or even irregular-shaped sewage pool. For example, if the sewage pool is circular, set the gradually shrinking concentric circles as the travel trajectory. Since the forward-looking radar 5 is installed in the front of the hull 1 and sensors 8 are installed on both sides, in case of encountering obstacles or blockages, it can choose to avoid or turn around; or directly select the remote control mode, and the operator directly manually remote controls through the remote control module. The remote control module selects the currently mature 2.4GH remote control unit on the market and can perform remote control operations up to 50 meters away at the farthest. This can ensure that the operator stays away from the sewage pool and avoids the risks of falling and suffocation.

[0019] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
