Description

Technical Field

[0001] The present invention relates to the field of water surface cleaning equipment, and more particularly to a salvage device. Background Art

[0002] Today, with the increasing abundance of commodities, commodity packaging is also increasing. In daily life, some packaging bags often float onto the water surface with the wind. The presence of floating objects on the water surface not only blocks the channels, but also causes problems such as water quality deterioration and microbial reproduction. Therefore, salvaging and cleaning the floating objects in irrigation channels is a necessary task in current agricultural production.

[0003] In the related art, the Chinese invention patent with the publication number CN104176200A discloses a floating object salvage ship, which includes a ship body, and a storage basket, a salvage unit, an extension unit, a drive unit, a steering unit, and a control unit all arranged on the ship body. The control unit is used to control the salvage unit, the extension unit, the drive unit, and the steering unit according to a control device on land; the salvage unit is used to salvage floating objects into the storage basket; the drive unit is used to drive the ship body to move forward; the steering unit is used to realize the steering of the ship body; the extension unit is used to accommodate the floating objects inside the extension unit when the ship body moves, so as to facilitate the salvage unit to salvage; the extension unit at least includes two sets of telescopic rod devices symmetrically arranged on both sides of the salvage unit. When the ship body moves, the floating objects are accommodated between the two telescopic rod devices for the salvage unit to salvage. The salvage unit at least includes a motor, a main shaft, a salvage frame, a mesh surface, a shaft sleeve, and a base. The base and the motor are respectively arranged at both ends of the main shaft, and the main shaft is connected to the ship body through the base and the motor. The main shaft is driven by the motor to rotate, and the other end of the main shaft is connected to the base through the shaft sleeve. The salvage frame is arranged outside the main shaft, and the mesh surface is installed on the salvage frame.

[0004] In view of the above related art, when the salvage frame rotates, the floating objects on the water surface can be transferred to the filter net at the bottom of the storage box through the salvage frame. Since there are a large number of objects such as packaging bags and beverage bottles in the floating objects that can hold river water, when the floating objects contain a large amount of river water, the ability of the salvage equipment to store floating objects is reduced, thereby reducing the salvage efficiency. Summary of the Invention

[0005] In order to improve the ability of the salvage equipment to store floating objects and the salvage efficiency of the salvage equipment, the present application provides a salvage device.

[0006] The salvage device provided by the present application adopts the following technical solutions:

[0007] A salvage device, comprising a hull and a filter screen. A collection chamber for accommodating floating objects is provided inside the hull. The filter screen is disposed inside the collection chamber. A transverse rod is provided above the filter screen, and an extrusion plate for extruding the floating objects is mounted on the transverse rod. A driving device for driving the transverse rod to reciprocate is provided on the hull.

[0008] By adopting the above technical solution, the transverse rod is located above the filter screen, and the extrusion plate is mounted on the transverse rod. The floating objects on the water surface can be salvaged onto the filter screen by the salvage frame. When the driving device drives the transverse rod to reciprocate, the transverse rod can drive the extrusion plate to extrude the floating objects on the filter screen, so that the extrusion plate can squeeze out the water carried by the floating objects, making the space occupied by the floating objects smaller, improving the storage capacity of the salvage device for floating objects, and thus improving the salvage efficiency of the salvage device.

[0009] Preferably, a strip-shaped chute is formed on the side wall of the collection chamber. An accommodation chamber communicating with the strip-shaped chute is formed inside the hull. The driving device is located inside the accommodation chamber. The driving device includes a motor fixedly connected to the inner wall of the accommodation chamber. A reciprocating screw is mounted on the output shaft of the motor. A sliding seat is fitted on the reciprocating screw. One end of the transverse rod passes through the strip-shaped chute and is fixed to the sliding seat, and one end of the transverse rod is slidably disposed inside the strip-shaped chute.

[0010] By adopting the above technical solution, one end of the transverse rod passes through the strip-shaped chute and is fixed to the sliding seat. The reciprocating screw is mounted on the output shaft of the motor, and the sliding seat is fitted on the reciprocating screw. When the motor is started, under the action of the transverse rod abutting against the top wall and the bottom wall of the strip-shaped chute, the reciprocating screw drives the sliding seat to reciprocate, so that the sliding seat can drive the extrusion plate to extrude the floating objects located on the filter screen.

[0011] Preferably, the filter screen includes a fixed section fixed to the inner wall of the collection chamber and a swinging section hinged to the side of the fixed end. The driving device includes a rotating drive mechanism for driving the swinging section to swing downward and a reset mechanism for driving the swinging section to swing upward.

[0012] By adopting the above technical solution, the fixed section is fixed to the inner wall of the collection chamber, and the swinging section is hinged to the side of the fixed section. When the drive mechanism drives the swinging section to swing downward, the floating objects extruded by the extrusion plate can fall to the bottom of the collection chamber, further improving the storage capacity of the salvage device for floating objects, and thus improving the salvage efficiency of the salvage device.

[0013] Preferably, a shaft hole communicating with the accommodating cavity is formed in the side wall of the collecting cavity. The hinge shaft of the swinging section and the fixed section passes through the shaft hole. The hinge shaft is rotatably arranged on the fixed section, and the hinge shaft is fixed to the swinging section. The hinge shaft is rotatably arranged in the shaft hole. The rotation driving mechanism includes a gear mounted on the hinge shaft. The gear is located in the accommodating cavity. A transfer rod is fixedly connected to the sliding seat, and a short rack that can be engaged with the gear is fixedly connected to the transfer rod.

[0014] By adopting the above technical solution, the gear is mounted on the hinge shaft, and the short rack is fixed to the sliding seat through the transfer rod. When the motor is started, the reciprocating screw drives the sliding seat to move. When the short rack is engaged with the gear, the short rack can drive the gear to rotate, so that after the floating matter on the filter screen is squeezed by the pressing plate, the swinging section can swing downward. Since the floating matter accumulates at one end of the swinging section far from the fixed section after being squeezed by the pressing plate on the filter screen, after the swinging section swings downward, the floating matter on the swinging section can fall below the filter screen.

[0015] Preferably, an installation ring groove is formed on the end surface of the gear, and an internal ratchet is fixed on the inner peripheral wall of the installation ring groove. A pawl that can be inserted between the teeth of the internal ratchet is hinged on the hinge shaft. A thrust spring is arranged between the hinge shaft and the pawl. One end of the thrust spring is fixed on the hinge shaft, and the other end of the thrust spring is fixed on the pawl. The short rack is located below the gear.

[0016] By adopting the above technical solution, when the sliding seat drives the short rack to move towards the swinging section, one end of the short rack is engaged with the gear. As the floating matter on the filter screen is squeezed by the pressing plate, the rotation of the gear drives the relative rotation of the ratchet and the hinge shaft. When the sliding seat moves in the reverse direction, the short rack drives the gear to rotate in the reverse direction. At this time, the pawl is inserted between the teeth of the ratchet under the elastic force of the thrust spring, so that the gear can drive the hinge shaft to rotate, thereby enabling the hinge shaft to drive the swinging section to swing downward. Furthermore, after the pressing plate squeezes the floating matter, the swinging section can automatically swing downward, and the floating matter can automatically fall below the filter screen.

[0017] Preferably, an annular groove is formed on the inner peripheral wall of the shaft hole. The reset mechanism includes a coil spring installed in the annular groove. One end of the coil spring is fixed on the inner peripheral surface of the annular groove, and the other end of the coil spring is fixed on the hinge shaft.

[0018] By adopting the above technical solution, when the sliding seat drives the short rack to move away from the swinging section, the swinging section swings downward. As the short rack moves away from the swinging section, when the short rack disengages from the gear, the return spring can drive the hinge shaft to rotate in the reverse direction, so that the hinge shaft drives the swinging section to swing upward.

[0019] Preferably, a sliding groove is formed on the end face of the output shaft of the motor. A sliding rod is installed on the end face of the reciprocating screw close to the motor. The sliding rod is slidably arranged in the sliding groove. A buffer spring is arranged in the sliding groove. One end of the buffer spring is fixed on the side face of the sliding groove far away from the reciprocating screw, and the other end of the buffer spring is fixed on the end face of the sliding rod far away from the reciprocating screw. A limiting component is arranged between the sliding rod and the rotating shaft of the motor to prevent the relative rotation between the sliding rod and the motor.

[0020] By adopting the above technical solution, the sliding rod is slidably arranged in the sliding groove. When there are more or harder floating objects fished on the filter net, during the process of the extrusion plate extruding the floating objects, the buffer spring can play a buffering role, reducing the stress at the connection between the cross bar and the sliding seat and improving the structural stability of the driving device.

[0021] Preferably, a limiting groove is formed on the inner peripheral wall of the sliding groove. The limiting component includes a limiting block fixed on the sliding rod, and the limiting block is slidably arranged in the limiting groove.

[0022] By adopting the above technical solution, the limiting block is slidably arranged in the limiting groove, thus preventing the synchronous rotation of the sliding rod and the motor rotating shaft.

[0023] Preferably, a drainage device is installed on the hull. The drainage device includes a pump body installed on the hull. A water suction pipe and a drainage pipe are installed on the pump body. One end of the water suction pipe far away from the pump body communicates with the bottom of the collection cavity.

[0024] By adopting the above technical solution, when the pump body is started, the pump body can pump the water in the collection cavity out of the collection cavity, thus increasing the storage capacity of the collection cavity.

[0025] Preferably, a control groove is provided on the inner wall of the collecting chamber, and the control groove is located below the filter screen. A control mechanism is installed in the control groove, and the control mechanism includes a control tube vertically installed in the control groove and a float located in the control tube. A water hole is provided on the side of the control tube, and a vertical groove is provided on the top wall of the control groove. A trigger rod is vertically slidably arranged in the vertical groove, a fixed contact piece is embedded on the inner wall of the vertical groove, and a moving contact piece that can contact the fixed contact piece is embedded on the trigger rod. A power supply is installed on the hull, the moving contact piece is electrically connected to one of the terminals of the pump body, the other terminal of the pump body is electrically connected to one of the electrodes of the power supply, and the other electrode of the power supply is electrically connected to the fixed contact piece.

[0026] By adopting the above technical solution, when the water level in the collecting chamber reaches a certain height, the float can push the trigger rod upward, so that the moving contact piece contacts the fixed contact piece, thereby making the electrical circuit of the pump body conductive, and then the water level in the collecting chamber reaches a certain height, and the pump body automatically discharges the water in the collecting chamber.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The transverse rod is located above the filter screen, and the squeezing plate is installed on the transverse rod. The floating objects on the water surface can be salvaged to the filter screen through the salvage frame. When the driving device drives the transverse rod to move back and forth, the transverse rod can drive the squeezing plate to squeeze the floating objects on the filter screen, so that the squeezing plate can squeeze out the water carried by the floating objects, so that the space occupied by the floating objects becomes smaller, and the ability of the salvage equipment to store floating objects is improved, thereby improving the salvage efficiency of the salvage equipment;

[0029] 2. The gear is installed on the hinge shaft, and the short rack is fixed on the sliding seat through the adapter rod. When the motor is started, the reciprocating screw drives the sliding seat to move. When the short rack is meshed with the gear, the short rack can drive the gear to rotate, so that after the squeezing plate squeezes the floating objects on the filter screen, the swing section can swing downward. After the squeezing plate squeezes the floating objects on the filter screen, the floating objects will accumulate at the end of the swing section away from the fixed section, so that after the swing section swings downward, the floating objects on the swing section can fall below the filter screen;

[0030] 3. When the sliding seat drives the short rack to move towards the swing section, one end of the short rack meshes with the gear. As the extrusion plate extrudes the floating objects on the filter net, the gear rotates to drive the ratchet and the hinge shaft to rotate relative to each other. When the sliding seat moves in the reverse direction, the short rack drives the gear to rotate in the reverse direction. At this time, the pawl is inserted between the teeth of the ratchet under the elastic force of the thrust spring, enabling the gear to drive the hinge shaft to rotate, so that the hinge shaft can drive the swing section to swing downward. Furthermore, after the extrusion plate extrudes the floating objects, the swing section can automatically swing downward, and the floating objects can automatically fall below the filter net.

At this time, the pawl 645 is inserted between the teeth of the ratchet wheel, so that the gear 641 drives the hinge shaft 23 to rotate, and then the hinge shaft 23 drives the swing section 22 to swing downward, so that the floating objects located on the swing section 22 after extrusion fall below the filter net 2. And when the short rack 643 moves towards the direction close to the other swing section 22 and disengages from the gear 641, the swing section 22 that swings downward can drive the swing section 22 to swing upward under the elastic force of the coil spring 651 until the swing section 22 is in a horizontal state.

[0061] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this.
