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: in modern river channel dredging, it is difficult for small river chain bucket dredgers to enter such shallow river channels for dredging, so the interception and drainage method is often used for excavation and dredging. However, this dredging method is costly, requires more equipment, and the river channel distance to be cleaned each time is limited, the efficiency is low, and it causes greater damage to the river embankments.

[0022] In view of the above problems, the present application discloses a riverbed silt cleaning structure for river channel regulation. The silt removal equipment is installed based on an operating platform 1. The operating platform 1 adopts a small platform with an air cushion to reduce the volume of the equipment. A water pusher 2 is arranged at the bottom of the operating platform 1. A steering gear 3 is arranged on the water pusher 2. The water pushing direction of the water pusher 2 is controlled by the steering gear 3. The water pusher 2 is a paddle structure. The directional water pushing is achieved by changing the preset direction by the steering gear 3. An electrical control box is arranged on the operating platform 1. The control systems of various electrical equipment are integrated in the electrical control box and a remote control device is arranged. The electrical equipment on the operating platform 1 can be controlled in real time by remote control, so that the operating platform 1 can be moved to different places in the river channel. Since the operating platform 1 has a shallow draft and is not limited to the depth of the river channel, it has better applicability.

[0023] Specifically, in order to better desilt the river channel and reduce the size of the equipment as much as possible, a chain bucket cleaner 4 is provided on the working platform 1, and a transmission conversion cylinder 5 is provided on one side of the chain bucket cleaner. A sludge pump 6 is connected to the bottom of the transmission conversion cylinder 5. By controlling the chain bucket cleaner 4, the bottom end of the chain bucket cleaner 4 is close to the river channel, and the chain bucket cleaner 4 is used to reciprocate to excavate the silt at the bottom of the river channel. The excavated silt is lifted to the working platform 1 by the chain bucket system, poured downward into the transmission conversion cylinder 5, and collected by the collecting effect of the transmission conversion cylinder 5. The bottom of the transmission conversion cylinder 5 is connected to a sludge pump 6, and a discharge pipe 11 is connected to the sludge pump 6 and extends to the river bank. The collected sludge is pumped to the river bank by the sludge pump 6, so as to facilitate further harmless treatment of the sludge.

[0024] According to the instruction manual Figure 1-3It can be seen that a pair of adjusting guide blocks 7 are arranged on both sides of the chain bucket cleaner 4, a control seat is arranged on the working platform 1, a pair of adjusting guide rails 8 are arranged on the control seat, a pair of adjusting guide blocks 7 are assembled on the pair of adjusting guide rails 8, and a control push rod 9 is arranged on the control seat to be linked with the pair of adjusting guide blocks 7;

[0025] In the specific implementation process, the control seat plays a supporting role for the chain bucket cleaner 4, and uses the control push rod 9 to push the pair of adjustment guide blocks 7 to move in the pair of adjustment guide rails 8, so that the pair of adjustment guide blocks 7 drive the chain bucket cleaner 4 to move, so that the depth of the chain bucket cleaner 4 inserted into the river channel can be adjusted, so that the chain bucket cleaner 4 is close to the riverbed silt, and the silt in the river channel is excavated according to the depth of the river channel;

[0026] According to the instruction manual Figure 1-3 It can be seen that the top of the transmission conversion cylinder 5 corresponds to the top of the chain bucket cleaner 4, and the bottom of the transmission conversion cylinder 5 is provided with a collecting hopper 10, which is connected to the sludge pump 6;

[0027] During the specific implementation process, the unloading position of the chain bucket cleaner 4 corresponds to the feed port of the transmission conversion cylinder 5, so that the sludge can smoothly enter the transmission conversion cylinder 5. A filter assembly is provided on the transmission conversion cylinder 5, and the filter assembly is assembled on the top of the transmission conversion cylinder 5. The filter assembly plays a filtering role on the sludge to prevent white garbage or large particles of stone from damaging the sludge pump.

[0028] As a preferred solution, further, the water thruster 2 is a propeller driven by a submersible motor, and the steering gear 3 is used to control the direction of the water thruster 2.

[0029] As a preferred solution, further, the outside of the working platform 1 is connected with a plurality of floats 12 to further increase the buoyancy of the working platform 1 , and water can be injected into the floats 12 as needed to increase the draft of the floats 12 .

[0030] As a preferred solution, further, according to the attached description Figure 1-3 It can be seen that the above-mentioned chain bucket cleaner 4 is composed of a transmission frame, a control motor installed on the transmission frame, a transmission chain linked to the control motor, and a plurality of chain dredging buckets;

[0031] In the specific implementation process, the transmission frame is used as the supporting frame of the chain bucket, and the chain dredging bucket is installed on the transmission frame with a chain. The reciprocating motion of the chain dredging bucket is controlled by controlling the motor drive chain to realize the excavation of the silt at the bottom of the river channel.

[0032] As a preferred solution, further, according to the attached description Figure 1-3It can be seen that the above-mentioned filter assembly is composed of a blanking plate 13 installed on the top of the transmission conversion cylinder 5, a nozzle 14 located on the blanking plate 13, and a filter screen plate 15 installed on the blanking plate 13;

[0033] During the specific implementation process, the silt falls from the chain bucket cleaner 4 onto the discharge plate 13. The discharge plate 13 is an inclined structure. The silt slides along the discharge plate 13. A submersible pump is arranged on the working platform 1. After the submersible pump takes water from the river, it pumps it into the nozzle 14. The nozzle 14 is evenly provided with a plurality of nozzles, and water is sprayed onto the discharge plate 13 through the plurality of nozzles. Under the impact of the water flow, the water further flushes the silt, increases the filtering effect of the silt, and improves the portability. As the flushed silt is accelerated to fall from the filter mesh plate 15 into the transmission conversion cylinder 5, large particles of garbage are intercepted and fall along the discharge plate 13 into a specially provided containing cylinder.

[0034] As a preferred solution, further, the discharge pipe 11 connected to the sludge pump 6 is a flexible hose with a telescopic structure, which can be easily arranged at different river bank positions according to needs.

[0035] From the above, it can be generally known that the riverbed silt cleaning structure used for river channel regulation adopts a floating working platform 1 as a working space, has a simple structure and good navigability, can effectively adapt to the dredging of shallow small rivers, and adopts remote control to control the dredging and movement. Since no manual assistance is required, the working process has a high degree of automation, the dredging operation is convenient and efficient, and the unmanned structure can be made more compact and portable, further improving the navigability.

[0036] Although 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.
