A method and device for intelligently receiving ship sewage on shore

Abstract

The embodiment of the present invention relates to the technical field of ships, and discloses a method and device for intelligently receiving ship sewage on shore, starting the intelligent receiving device for ship sewage on shore; identifying the state of the first hose, and the state of the first hose includes the knotting state of the coil , Unwinding and knotting state, controlling the speed of unwinding the pipe based on the identification result of the first hose state, and controlling the discharge of sewage; in response to the signal of collecting the pipe, identifying the state of the second hose, and controlling the speed of collecting the pipe based on the identification result of the state of the second hose, until the hose is completely stored. The present invention is calculated according to the diameter of the hose and the coil, and the combination of the angular velocity and the linear velocity during operation, so that the hose can be retracted freely, saving manpower, and avoiding abnormal phenomena such as broken tubes or hose entanglements during the operation process, which is reasonable. The laid hose improves the safety of sewage transfer, reduces the complexity of operation and the dependence on manpower.

Description

technical field [0001] The embodiment of the invention relates to the technical field of ships, in particular to the field of receiving sewage from ships. Background technique [0002] In recent years, inland waterway shipping has developed rapidly and has become an important pillar of economic and social development. However, large-scale shipping activities inevitably pollute the surrounding environment. As the most common ship pollutant, domestic sewage from inland ships has attracted more and more attention in countries all over the world. The "Regulations of the People's Republic of China on the Prevention and Control of Vessel Pollution of Inland River Waters Environmental Management" requires that ships navigating, berthing and operating in inland waters must not discharge pollutants into inland waters in violation of laws, administrative regulations, norms, standards and the provisions of the Ministry of Transport. Pollutants from ships that do not comply with the di...

Problems solved by technology

The existing sewage transfer needs to use the transfer pump of the sewage storage tank on the ship or install a temporary transfer pump for the transfer of sewage. Although the transfer of the ship's sewage to the shore is realized, the hose between the shore receiving device and the transfer pump is manually laid The way of laying the hose is time-consuming and laborious; when laying the hose manually, the length of the hose is selected according to experience, and the actual length of the hose will change at any time due to the position of the ship when it is moored. If the hose is too long, it will easily bend. If the hose is too short, it will not be able to connect the receiving device and the delivery pump smoothly, and multiple manual adjustments and inspections are required; when the pipe is collected manually, the sewage in the hose will be removed when the pipe is collected after each rotation. Spill on the ship or in the water source where it is located; in addition, the existing device cannot realize flow monitoring and automatic recording, and each time the sewage is transferred, the staff needs to manually confirm the various information of the ship and record it in time. complex

[0004] In the prior art, there are some devices that use motors to control the retraction and release of the hose. However, in the above-mentioned retraction process, only the automatic retraction control of the hose or the limitation and alarm of the retractable length are realized. The automatic The control device is only a simple switch control, that is, it responds to the instructions of the staff to retract and release the tube, and can calculate the length of the retractable tube, but the simple retractable switch control in the prior art cannot realize the intelligent detection and monitoring of the hose. Adaptive processing cannot intelligently detect the knotting state of the hose during the retraction process, and furthermore, it cannot realize the intelligent control of the retraction process on the basis of automatic identification status. In addition, it cannot solve the hose knotting through adaptive adjustment The problem is that the existing automatic control device for retracting and unwinding tubes has low intelligence and weak ability to deal with abnormal situations.

[0005] Although there is a retractable control device for cables in the prior art, such as an automatic retractable control device for ordinary cables or solid-core cables, from the perspective of the controlled object, cable materials such as ordinary cables or solid-core cables Harder, the above-mentioned cables are less likely to be knotted, and because the cable material is harder, there is still a workable space between the cables in the knotted state, which has little impact on the total amount and speed of the transmitted material, and Once there is a knotted state, due to the hard material of the cable, the knotting problem cannot be automatically solved through retractable control; on the other hand, the sewage discharge pipes used in ships are made of soft materials, and once a knotted state occurs due to the soft material, the transmission space is rapid reduce the transmission speed and flow rate, which greatly affects the efficiency of sewage discharge. In the prior art, there is no need to detect and solve the knotted state in the cable automatic retractable control device in other fields, and due to Due to the difference in materials and application requirements, it is difficult to directly transfer the cable automatic retractable control devices in other fields to the field of ship sewage discharge
