Description

Technical Field

[0001] The present invention relates to the technical field of sediment collection equipment, and in particular to a device and method for collecting underwater sediment in a coastal zone. Background Art

[0002] Ocean detection, also known as ocean exploration, ocean detection technology and equipment engineering are the foundation for ocean development, ocean protection and sustainable development. Building a strong ocean country with advanced ocean technology, developed ocean economy, ocean ecological civilization and strong comprehensive ocean national strength is inseparable from the vigorous development of ocean detection and equipment engineering. With the enhancement of environmental awareness, people's protection of the ocean is also gradually developing. In response to the appearance of foreign matter in seawater, in order to ensure the health of water quality, relevant collection devices are needed to collect and detect foreign matter in seawater to ensure the safety of water quality.

[0003] Patent document: CN113252404B discloses a depth-adjustable coastal underwater sediment collection device, comprising "a base frame, the upper end face of the base frame being fixedly connected to one end of a gantry frame by bolts, the side end face of the base frame being fixedly connected to a support assembly by bolts, the base frame being connected to a collection assembly, the collection assembly being arranged through the base frame, the side face of the collection assembly being fixedly connected to an extractor, the input end of the extractor being connected to a hose, the hose being fixedly connected to an internal tube, the internal tube being connected to an extraction head, which can be adjusted in height, and the collection depth of the collection bucket being adjustable. When the collection bucket is collecting underwater sediment, the water source that first enters the top of the collection bucket is extracted, and then the extraction head cooperates with a spring to seal the gap, thereby completing the extraction process and leaving sufficient collection space in the collection bucket to ensure collection efficiency."

[0004] However, in the above patent, the device adjusts the extraction work of the sediment at different depths by adjusting the height of the extraction head. However, the sediments in the coastal water are mostly formed by the accumulation of debris falling on the coast and are affected by the push of waves. Therefore, there are more sediments near the coast. When the above device is in use, its collection structure is not sufficiently applicable to the shore structure, and the extraction work of the above device lacks range limitation. The sediment samples are distributed widely and are not concentrated enough, which affects the efficiency of the device's collection work.

[0019] S4. The device is installed by fitting it with the inclined coast. Therefore, when installing the device, the shore structure can be constructed in advance to meet the installation of the device, and the device is plugged into the shore structure by plugging. The installation can be carried out in a wide range. At the same time, through the setting of through grooves and docking rods, two sets of identical fixed frames can be laid, and the two can be installed and connected by the penetration of the docking rod.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention provides a screen and a collection frame. The collection frame can cooperate with the setting of the screen to play a dual sample collection role, so as to collect samples of objects in the screen and the collection frame. The screen can collect the sliding of foreign objects, and also screen the objects entering the collection frame. The collection frame can be used for sediment accumulation. The collection frame can accumulate the sediment. After the collection frame is pulled out, the accumulation of sediment increases the efficiency of the sampling work of the device.

[0022] 2.

The filling of the sand and gravel layer can also play a role in increasing weight. The counterweight cover has a certain weight, so the counterweight frame after filling the sand and gravel layer can be installed and sealed to prevent the entry of seawater. The setting of the counterweight frame can press down the bottom fixed plug-in rod, thereby increasing the stability of its insertion, and then increasing the stability of the structural installation when the device is in use. Since the counterweight frame is located above the entire device, when it exceeds the height of seawater, the counterweight cover can be removed to install and connect the fence or other warning devices to the counterweight frame.

An anti-collision plate 36 is fixedly mounted on one side of the connecting card block 35, and two groups of anti-collision strips 37 are fixedly mounted on one side of the anti-collision plate 36.

[0035] By setting the mounting frame 1 and the fixing frame 2 and the inclination of the device structure, the device is installed on the shore. The inclination of the mounting frame 1 is matched with the coast, so that it fits with the shore.
