Description

a sweeping boat

technical field

The invention relates to the technical field of water surface cleaning equipment, in particular to a cleaning vessel.

Background technique

There is a lot of garbage floating on the lake now, which seriously affects the water quality and the water surface landscape. Therefore, it is necessary to collect the surface garbage quickly, and the sweeping boat came into being. At the same time, the main operation modes of the hull are propeller propulsion and water spray type. The water jet propulsion is obtained by the reaction force of the water flow ejected by the propelling water jet pump, and the steering of the ship is realized by distributing and changing the direction of the jet flow by steering the rudder and the reverse rudder device.

General cleaning boats collect garbage near the surface of the water, and then manually pick up the garbage and place it on the ship.

In view of the above-mentioned related technologies, the inventor believes that there is a disadvantage that it is inconvenient to manually salvage the garbage on the water surface onto the ship.

SUMMARY OF THE INVENTION

In order to facilitate the salvage of garbage on the water surface, the present application provides a sweeping boat.

A cleaning vessel provided by the application adopts the following technical solutions:

A sweeping boat, comprising a hull, a gathering tank opened at the bow of the hull, a garbage tank opened on the upper surface of the hull near the gathering tank and used for placing garbage, and a garbage tank located at the bow of the hull and capable of gathering garbage on the water into the gathering tank Garbage gathering device, a hull power device located at the stern of the hull and controlling the movement of the hull, the hull is provided with a salvage concave net body located at the gathering trough that can extend below the water surface of the gathering trough, and the hull is provided with a salvage concave net body that can drive the salvage concave net body to rotate To move to the salvage concave net body rotating mechanism above the garbage chute.

By adopting the above technical solution, when the salvage concave net body is located in the water of the gathering tank, the hull moves forward through the hull, so that the garbage on the water surface enters the gathering tank, and the garbage entering the salvage concave net body is blocked and no longer moves. When the garbage in the net body is full to a certain extent, the salvage concave net body is rotated, so that the salvage concave net body is turned over, and the salvage concave net body is moved to the top of the garbage chute, so that the garbage in the salvage concave mesh body is dumped into the garbage chute. It is more convenient to pick up the garbage on the water surface in the gathering tank without manual labor, which can also improve the efficiency of surface garbage salvage and reduce labor costs.

Preferably, the salvage concave net body rotating mechanism comprises two supporting columns fixedly connected to the upper surface of the hull, a rotating rod rotatably connected between the two supporting columns, a connecting rod fixedly connected to the rotating rod, and a A rotating rod motor, a motor sheave coaxially fixedly connected to the output shaft of the rotating rod motor, a rotating rod sheave coaxially fixedly connected to one end of the rotating rod, a transmission belt connected to the rotating rod sheave and the motor sheave, a connecting rod One end close to the salvage concave mesh body is bent and the bending direction of the connecting rod is away from the salvage concave mesh body.

By adopting the above-mentioned technical solution and starting the rotating rod motor, the rotating rod can be driven to rotate through the transmission belt, and then the salvage concave net body can be driven to rotate around the axis of the rotating rod. In the process of driving the salvage concave net body to rotate, it is more difficult to bend, and when the garbage is dumped into the garbage chute, it also reduces the rotation angle of the rotating rod, which is convenient for the salvage concave mesh body to pour the garbage into the garbage chute. middle.

Preferably, a push plate is slidably connected to the two opposite inner walls of the gathering tank along the length of the hull, the surface of the push plate is evenly provided with several water passages, and the hull is provided with a push plate driving mechanism that can drive the push plate to slide along the length of the hull.

By adopting the above technical solution, the push plate is moved to prevent the garbage in the gathering tank from moving to the position where the salvage concave net body cannot be stored and salvaged during the process of rotating the salvage concave net body to pour the garbage into the garbage chute. . Therefore, more garbage in the gathering tank cannot enter into the salvage concave net body, and at the same time, the water passing hole can reduce the resistance of the water when the push plate moves.

Preferably, the push plate driving mechanism includes connecting block grooves opened on two opposite inner walls of the gathering groove along the length of the hull; The two connecting blocks in the block groove, the guide rod fixedly connected to the connecting block groove far from the rotating rod motor, the connecting block screw rotatably connected to the connecting block groove close to the rotating rod motor, and the coaxial fixed connecting block screw The screw bevel gear close to one end of the rotating rod motor, the motor bevel gear that is coaxially fixedly connected to the output shaft of the rotating rod motor and meshed with the screw bevel gear, the guide rod is penetrated and slidably connected to a similar connecting block, and the screw of the connecting block is penetrated. It is set and screwed to a similar connecting block.

By adopting the above technical solution, when the rotating rod motor is restarted to drive the salvage concave net body to rotate, the rotating rod motor can drive the connecting block screw to rotate through the motor bevel gear and the screw bevel gear, so that the movement of the push plate and the salvage concave net body are made. The rotation of the trough is performed synchronously, so that the salvage concave net body and the push plate can be better matched, and most of the garbage in the gathering tank has been salvaged.

Preferably, the connecting block grooves are inclined, and the openings of the two connecting block grooves are both facing the water surface in the collecting groove.

By adopting the above technical solution, it is difficult for water to accumulate in the groove of the connection block, and the water accumulation in the groove of the connection block is avoided, which makes it difficult for the guide rod and the screw of the connection block to move between the connection blocks.

Preferably, the garbage gathering device includes two aggregates rotatably connected to both sides of the opening of the gathering tank, two hydraulic cylinder tanks located at the bow of the hull, the cylinder body is hinged to the inner wall of the hydraulic cylinder tank and the power The rod extends out of the cylinder slot and is hinged to the hydraulic cylinder of the aggregate, the end of which facing away from the hull is blade-shaped.
