Description

Deep bottom suction cup type dredging and sand discharging device with floating function

Technical Field

The invention relates to the technical field of dredging and sand-removing equipment, in particular to a deep-bottom sucker type dredging and sand-removing device with a floating function.

Background

In the water conservancy field, the reservoir capacity loss caused by sediment accumulation continuously influences the functions, safety and comprehensive benefits of the reservoir. In the face of the continuous aggravation of reservoir sediment accumulation and the continuous increase of the demand of human beings for water resources, the problem of reservoir sediment accumulation is more and more highly emphasized, and how to manage the reservoir sediment accumulation, maintain and restore the functions of the established reservoir becomes an important means for solving the problems of water resource shortage and serious flood disasters. Due to slow water flow in water areas such as river channels, reservoirs and the like, a large amount of sediment such as sediment, broken stone and the like are deposited, so that the smoothness of water flow and the normal operation of hydraulic facilities are affected. Advanced technical means such as mechanical dredging, chemical cleaning and the like are needed for sediment treatment so as to ensure that normal operation of hydraulic facilities and engineering safety are not affected. Long-term deposition of sediment may cause problems such as riverbed elevation, reservoir capacity reduction and the like, and increase the risk of natural disasters such as flood, drought and the like.

In the field of water environments, sediments in the water environment may contain a variety of contaminants including heavy metals, organics, nutritive salts, etc., which may be from industrial wastewater, agricultural activities, domestic sewage, etc., which present challenges to treatment. Sediment in the water may spread throughout the water area, affecting the quality of the water and the health of the ecosystem. Different treatments, such as physical, chemical, biological, etc., are required for different types of deposits, which requires high demands and complexity of the treatment technique. The treatment of the sediment may have an effect on the ecological environment of the water, such as disruption of ecological balance, influence on the survival of aquatic organisms, etc.

In the water supply field, along with the aggravation of environmental pollution, many water source sites are affected by different degrees, so that sediment and pollutants exist in the water supply process, and the treatment difficulty and risk are increased. In order to ensure the quality and safety of the water supply, it is necessary to treat the sediment efficiently, which requires advanced treatment techniques such as filtration, adsorption, oxidation, etc. The water supply apparatus is required to be periodically maintained and managed, including cleaning, sterilizing, and replacing parts, etc., to ensure the normal operation of the apparatus and the safety of water supply. In order to ensure the quality and safety of the water supply, it is necessary to detect and monitor the water quality and to discover and treat sediment and contaminant problems in time.

In the marine field, the sediment in the ocean may come from different sources, including river-carried sediment, wind-borne dust, biological remains, etc., which are of different kinds and properties, and present a challenge to the process. The distribution of sediment in the ocean is uneven, some areas may have a large amount of sediment, and some areas may have little sediment, which increases the difficulty and cost of the process. Marine environments have high complexity, including variations in water flow, temperature, salinity, light, etc., which can affect the properties and treatment of the sediment. The treatment of sediment may have an effect on marine ecology, such as disruption of the ecological balance of the ocean floor, impact on the survival of marine organisms, etc.

In the field of aquaculture, sediments produced in the aquaculture contain a large amount of organic matters, and harmful substances such as ammonia, hydrogen sulfide and the like can be produced in the decomposition process of the organic matters, so that water body is polluted. Harmful substances such as medicines, heavy metals and the like can be remained in the sediment, and the substances can permanently pollute the water body. The amount of sediment produced in the breeding industry is large, and an efficient treatment method is needed to ensure the cleaning of the water body.

In the mechanical field, deposits in mechanical systems can come from a number of sources, including lubricants, fuels, coolants, etc., which are of various kinds and properties, and present challenges for processing. Many mechanical devices have complex internal structures, such as narrow channels, deep holes, etc., that make it difficult for the sediment to enter and clear. Many mechanical components have high precision requirements, such as bearings, gears, etc., and the presence of deposits can cause increased wear on these components, degrading equipment performance. Some mechanical devices need to operate in high temperature and high pressure environments, which makes the deposit more difficult to remove and increases the difficulty of handling. The deposits can affect the proper operation of the equipment, can cause equipment failure, reduce equipment performance, and even raise safety concerns.

In the chemical industry, the sediment composition is complex and often contains various chemical substances and particulate matters, and the substances interact with each other, so that the treatment difficulty is increased. The treatment process of chemical sediment needs to ensure safety, and harmful substances are prevented from being generated in the treatment process, thereby affecting the environment and human health. In the long-term use of chemical equipment, the sediment can influence the normal operation of the chemical equipment, so that the chemical equipment needs to be cleaned and maintained frequently, and the normal operation of the chemical equipment is ensured. In the chemical production process, the continuity of the whole production process can be affected by the faults of any equipment, so that the treatment of sediment is also an important link for ensuring the production continuity.

The above mentioned owners are mainly described around reservoir sand discharge as a typical feature. Aiming at the sand discharge of the reservoir, the traditional sand discharge modes comprise flood-stagnation sand discharge, heavy-duty sand discharge, emptying sand discharge and concentrated flushing, and the sand discharge modes have high operation difficulty and require a large amount of manpower, material resources and financial resources. Compared with the traditional sand discharging mode, the sand discharging ship has the advantages that the sand discharging difficulty is greatly reduced, the operation is simple and convenient, the flexibility is realized, the investment and operation cost is low, but the sand discharging ship also has the defects of too large volume and relatively clumsy operation. At present, there is no sand removing tool which is convenient to operate and can achieve the same effect with a sand removing ship, and therefore, in the fields of water conservancy, water environment, water supply, sea, aquaculture, machinery, chemical industry and the like, a deep-bottom sucker type dredging sand removing device with a floating function is needed to solve the defects.
