Technical Field

[0001] This utility model relates to the field of dredging engineering equipment technology, and in particular to an angle sensing device for the movable cover of the dredging suction hopper. Background Technology

[0002] Trailing suction hopper dredgers are a commonly used type of vessel in dredging projects. The dredger head is an important tool for dredging operations, consisting of the dredger head body, a movable cover, and a dredger tooth frame mounted on the movable cover. The dredger head body and the movable cover are connected by a pin, allowing the movable cover to have a certain range of rotation. During the removal of silt, the movable cover is required to apply appropriate pressure to the bottom of the water so that the multiple dredger teeth on the dredger tooth frame can fully excavate the silt without being damaged. However, when the thickness of the silt at the bottom of the water is uneven, the movable cover will frequently rotate relative to the dredger head body according to the bottom topography, making it impossible for the dredger head to apply appropriate pressure to the bottom of the water, resulting in the dredger head not being in a stable and good working state.

[0022] This utility model provides an angle sensing device for the movable cover of the shovel head of a trailing suction dredger, including a shovel head body 101, a movable cover 102, a shovel tooth frame 103, a drive device 104, a sensor 105, a processor 106, and a crushing mechanism. The crushing mechanism includes a screening component, two mounting seats 107, two crushing rollers 108, a mounting shell 109, two rotating shafts 110, a belt 111, a first drive source 112, and two mating plates 113. The screening component includes a filter screen 114, four connecting components, a second drive source 115, and a cam 116. The connecting components include a support plate 117, a telescopic rod 118, and a spring 119. The above structure solves the problem that during the shovel suction process, it is impossible to crush stones in the mud and sand of the riverbed or seabed, which easily causes blockage and affects the efficiency of the shovel suction.

[0023] In a specific embodiment, the rake head body 101 is movably connected to the movable cover 102, the rake tooth frame 103 is installed below the movable cover 102, and the rake tooth frame 103 is provided with a plurality of rake teeth 120. The drive device 104 is connected between the rake head body 101 and the movable cover 102, the processor 106 is disposed above the rake head body 101, and the sensor 105 is installed above the rake tooth frame 103. During rakeing and suction, the sensor 105 monitors the movable cover 102 and transmits the monitoring data to the processor 106. The processor 106 drives the drive device 104 to operate and adjust the angle of the movable cover 102.

[0024] The screening assembly is disposed within the movable cover 102. Two mounting bases 107 are mounted opposite each other within the movable cover 102. One end of each of the two crushing rollers 108 is rotatably connected to one of the two mounting bases 107. The mounting shell 109 is mounted on the outer wall of the movable cover 102. Two rotating shafts 110 are rotatably mounted on the outer wall of the movable cover 102, and each rotating shaft 110 passes through the movable cover 102 and is fixedly connected to the other end of each of the two crushing rollers 108. A belt 111 is sleeved on the outer wall of each of the two rotating shafts 110. The first drive source 112 is mounted within the mounting shell 109, and its output end is fixedly connected to the rotating shaft 110. Two mating plates 1... 13 is installed inside the movable cover 102. The mounting shell 109 is used for waterproofing and protecting the first drive source 112. During the raking process, the screening component screens the mud and sand, intercepting larger stones. After the mud, sand and smaller stones pass through the screening component, the first drive source 112 operates. The rotating shaft 110 connected to the first drive source 112 rotates. Under the action of the belt 111, another rotating shaft 110 rotates, and the two crushing rollers 108 rotate and cooperate with the mating plate 113 to crush the smaller stones. This further avoids the accumulation of stones and blockage, solving the problem that during the raking process, it is impossible to crush the stones in the mud and sand of the riverbed or seabed, which easily causes blockage and thus affects the raking efficiency.

[0025] The four connecting components are respectively disposed inside the movable cover 102. The filter screen 114 is connected to the four connecting components. The second drive source 115 is fixedly connected to the movable cover 102 and located inside the mounting shell 109. The output end of the second drive source 115 passes through the movable cover 102. The cam 116 is fixedly connected to the output end of the second drive source 115 and is in contact with the filter screen 114. When the second drive source 115 operates, the cam 116 rotates and squeezes the filter screen 114. When the cam 116 disengages from the filter screen 114, the filter screen 114 vibrates under the action of the connecting components, preventing silt from clogging the filter screen 114 and affecting the dredging efficiency.

[0026] The support plate 117 is fixedly connected to the movable cover 102 and is located inside the movable cover 102. The telescopic rod 118 is connected between the support plate 117 and the filter screen 114. The spring 119 is sleeved on the outer side wall of the telescopic rod 118. The support rod is used to install the telescopic rod 118. The second drive source 115 operates, driving the cam 116 to rotate. When the cam 116 contacts the filter screen 114, it squeezes the filter screen 114, and the telescopic rod 118 and the spring 119 are stretched. When the cam 116 disengages from the filter screen 114, under the action of the elastic force of the spring 119, the spring 119 and the telescopic rod 118 contract, pulling the filter screen 114 back to its original position. This causes the filter screen 114 to vibrate, preventing mud and sand from clogging the filter screen 114.

[0027] Second Embodiment

[0028] Please see Figure 5 , Figure 5 This is a schematic diagram of the overall structure of the second embodiment of the present invention.

[0029] Based on the first embodiment, the angle sensing device of the moving cover of the shovel hopper boat of this utility model also includes a heat dissipation mechanism, which includes a heat-conducting plate and multiple heat dissipation fins.

[0030] In a specific implementation, the heat dissipation mechanism is disposed on the outer side wall of the mounting shell 109. The heat dissipation mechanism is used to dissipate heat and ensure the normal operation of the first drive source 112 and the second drive source 115 inside the mounting shell 109.

[0031] The heat-conducting plate is fixedly connected to the mounting shell 109 and located on the outer wall of the mounting shell 109. Multiple heat sinks are respectively fixedly connected to the heat-conducting plate and located on the outer wall of the heat-conducting plate. When the first driving source 112 and the second driving source 115 operate, they dissipate heat. The heat-conducting plate absorbs the heat inside the mounting shell 109 and transfers it to the multiple heat sinks, which then dissipate it to the outside, preventing the temperature inside the mounting shell 109 from becoming too high and affecting the normal operation of the first driving source 112 and the second driving source 115.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
