DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an implementation scheme: the salvage equipment in modern water conservancy projects is usually used in the upper layer of the water surface. The salvage of the lower layer of garbage close to the riverbed is usually carried out in conjunction with dredging. However, in actual application, the salvage operation in the dredging method is inefficient and energy-intensive.

[0022] In view of the above problems, the present application discloses a bottom salvage device for water conservancy engineering, comprising a fixed frame 1, the fixed frame 1 is a rectangular frame, a salvage roller belt 2 is arranged on the fixed frame 1, a pair of sliding rails 3 are symmetrically arranged on both sides of the tail end of the fixed frame 1, and a pair of sliding blocks 4 are assembled on the pair of sliding rails 3;

[0023] In the specific implementation process, the salvage roller belt 2 is installed and the tail end is fixed by the fixed frame 1. A pair of sliding rails 3 are provided at the tail end of the fixed frame 1 to guide the pair of sliding blocks 4. The pair of sliding blocks 4 are connected to the salvage device at the bottom. After the salvage device contacts the riverbed, due to the ups and downs of the riverbed, the salvage device moves up and down. The pair of sliding blocks 4 and the pair of sliding rails 3 are used to guide and limit the salvage device at the bottom, thereby ensuring that the salvage device can move with the ups and downs of the riverbed and maintain a horizontal posture of the salvage device.

[0024] Furthermore, a pair of floating rods 5 are extended from the bottom ends of the pair of sliding blocks 4, and a pair of traveling rollers 6 are arranged at the bottom ends of the pair of floating rods 5. The pair of floating rods 5 are extended as the pair of sliding blocks 4, so that the bottom ends of the salvage roller belts 2 are extended to the position of the riverbed. At the same time, the pair of floating rods 5 are supported by the pair of traveling rollers 6, so that the pair of traveling rollers 6 contact the riverbed ground. When the salvage device moves forward with the hull, the supporting effect of the rollers matches the bottom terrain of the riverbed, ensuring that the salvage device can effectively approach the riverbed position.

[0025] According to the instruction manual Figure 1-3 It can be seen that the bottom ends of a pair of floating rods 5 are connected by movable rollers 7, and the top ends of a pair of sliding blocks 4 are connected by conversion rollers 8; in the specific implementation process, the conversion roller 8 is used to change the salvage roller belt 2 from a horizontal posture to a posture perpendicular to the horizontal, and a pair of side pressure rollers 10 are arranged at the turning position of the salvage roller belt 2 to fit the bottom surface of the salvage roller belt 2. The movable roller 7 serves as a transmission mechanism with the bottom end close to the riverbed. The salvage roller belt 2 is matched with the movable roller 7 and the conversion roller 8, so that the salvage roller belt 2 extends to the riverbed position, and then cooperates with a number of salvage spikes 9 evenly arranged on the salvage roller belt 2 to salvage the bottom garbage close to the riverbed during the rotation of the salvage roller belt 2. The length of the plurality of salvage spikes 9 is equal to or less than the length of the pair of traveling rollers 6;

[0026] Furthermore, the end of the salvage roller belt 2 is connected to a power assembly 11, and a separator 12 is provided on the head end of the fixed frame 1. The power assembly 11 is used to drive the salvage roller belt 2 to circulate, and the separator 12 is used to separate the salvaged garbage.

[0027] Furthermore, a sliding column 13 is provided on the sliding block 4, and an adjusting screw 14 is assembled on the sliding column 13. The end of the adjusting screw 14 is connected to a support rod, and the side pressure roller 10 is movably installed on the support rod. By rotating the adjusting screw 14 to engage the adjusting screw 14 with the sliding column 13, the side pressure roller 10 can be pushed to move, thereby adjusting the side pressure roller 10 to fit the bottom surface of the salvage roller belt 2.

[0028] Furthermore, the pair of floating rods 5 are a pair of pneumatic struts, and a pair of floating assembly blocks 15 are mounted on the pair of pneumatic struts. In the specific implementation process, the floating rods 5 and the floating assembly blocks 15 work together as buoyancy devices to reduce the pressure of the floating roller on the riverbed, thereby preventing the equipment from sinking into the riverbed. At the same time, the floating rods 5 have a certain amount of space for swinging and floating. The air-charging and air-discharging valve cores arranged on the pair of floating assembly blocks 15 are used to adjust the air-charging and air-discharging valve cores, and the air-charging and air-discharging valve cores are adjusted according to the hardness of the riverbed to keep the equipment always close to the bottom of the riverbed.

[0029] According to the instruction manual Figure 1-3 It can be seen that the power assembly 11 includes a driving motor 111, and the driving motor 111 is arranged parallel to one side of the inner end shaft of the salvage roller belt 2, and a reducer 112 is arranged on one side of the driving motor 111, and the reducer 112 is respectively connected to the driving motor 111 and the inner end of the salvage roller belt 2;

[0030] In the specific implementation process, the reducer 112 is driven to rotate by the driving motor 111, and the input end of the reducer 112 is connected to the driving motor 111 through a coupling to increase the torque output by the reducer 112, and the reducer 112 contacts the end groove of the salvage roller belt 2, thereby making the salvage roller belt 2 circulate.

[0031] From the above, it can be generally known that the bottom salvage equipment for water conservancy projects adopts a floating structure design that can extend the salvage device to the riverbed for salvage. During the salvage process, the buoyancy rod and the buoyancy assembly block can keep the salvage device always close to the riverbed and move forward, and cooperate with the circulating chain salvage roller belt 2 and the salvage nails 9 to salvage the garbage on the bottom layer. The structure is simple, which solves the problem that conventional salvage devices cannot fit the bottom layer of the river channel for salvage operations.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
