Description

Technical Field

[0001] The utility model relates to the technical field of safety protection systems for port container cranes, and particularly relates to a power failure protection warning device for temporary navigation lights during the shipping of container cranes and a quay crane. Background Art

[0002] A quay crane (referred to as a shore crane) is a specialized device for loading and unloading container ships at a container terminal, generally installed at a port container terminal. It is huge in size, and the highest point of the machine can reach more than seventy meters. The production of shore cranes is generally located in a specialized production base. After production, they are shipped to the user terminals by sea. User terminals are spread all over the world, and the shipping time can sometimes reach three or four months. Therefore, during the shipping process, due to its high height and large size, navigation lights must be installed to indicate its own position and movement direction to ensure safety.

[0003] A shore crane needs to install three navigation lights, which are located at the front end, the rear end, and the highest point of the shore crane respectively. Since the shore crane itself has no power during the shipping process, it is necessary to borrow the power supply on the transport ship to install temporary navigation lights. The position of the navigation lights is at a high altitude, which is not easy for the crew on the ship to observe and cannot be inspected frequently. The traditional temporary navigation lights only connect three lights by borrowing the power supply on the ship. However, during the long-term sea transportation process, there are often phenomena that the navigation lights lose power and do not light up or the bulbs are damaged and do not light up. This poses a great safety risk to sea transportation. If a collision occurs due to the non-lighting of the navigation lights, it will cause a great accident and huge losses.

[0004] After analysis, there are the following two situations in which the temporary navigation lights may not light up during the shipping process:

[0005] First, the temporary navigation lights lose the main power supply, resulting in power failure and non-lighting.

[0006] Second, although the temporary navigation lights have not lost power, the bulbs are damaged, resulting in non-lighting.

[0007] In order to eliminate the safety risks caused by the non-lighting of navigation lights during sea transportation, for the two situations that may cause the navigation lights not to light up, the inventor of the present application designed a power failure protection warning device for temporary navigation lights during the shipping of container cranes and a quay crane, in order to overcome the above technical problems.

[0039] The navigation light system 200 includes a main navigation light 220. The main navigation light 220 is electrically connected to the electrical output port of the uninterruptible power supply 100. The audible and visual alarm 400 is electrically connected to the second control interface of the network controller 300.

[0040] Currently, the temporary navigation lights on the quay crane are respectively installed at the three positions of the front end, the rear end, and the top end of the quay crane, and the power required for the navigation lights is drawn from the transport ship.

[0041] Preferably, for the power failure protection warning device of the present utility model, the power supplies of the uninterruptible power supply 100 and the network controller 300 are provided by the transport ship through a temporary wire. The power supply of the navigation lights is provided by the output of the uninterruptible power supply 100. The uninterruptible power supply 100 is preferably a small 220-volt uninterruptible power supply with a socket.

[0042] The power failure protection warning device of the present utility model can ensure that when the power supply of the transport ship fails, the uninterruptible power supply 100 can ensure that the navigation light system 200 can continue to be powered for a period of time.

[0043] Preferably, when the power supply of the transport ship fails, the network controller 300 can transmit a power failure signal to various terminal devices such as mobile phones and tablets through the network; at the same time, the network controller 300 controls the contactor to close, so that the sound and light alarm 400 is powered on for sound and light alarm.

[0044] The power failure protection and early warning device for the temporary navigation lights of the container crane of the present utility model enables the navigation lights to give an early warning in time after a power failure and can continue to work for a period of time to give maintenance personnel sufficient time for inspection and maintenance, avoiding collision accidents caused by the non - illumination of the navigation lights during this period.

[0045] As Figure 1 shown, as the power failure protection and early warning device for the temporary navigation lights of the container crane of the present utility model, the power failure protection and early warning device further includes a circuit breaker 500. One end of the circuit breaker 500 is electrically connected to the power supply of the transport ship, and the other end of the circuit breaker 500 is electrically connected to the uninterruptible power supply 100 and the network controller 300. The circuit breaker 500 disconnects when the power supply of the transport ship fails.

[0046] As Figure 2 shown, as the power failure protection and early warning device for the temporary navigation lights of the container crane of the present utility model, the navigation light system 200 further includes a current detection relay 210 and a standby navigation light 230.

[0047] The main navigation light 220 is electrically connected to the control loop of the current detection relay 210.

[0048] The standby navigation light 230 is electrically connected to the load loop of the current detection relay 210, and the load loop is normally open; when the control loop is open, the load loop is connected.

[0049] As Figure 2 shown, as the power failure protection and early warning device for the temporary navigation lights of the container crane of the present utility model, the navigation light system 200 further includes a buzzer 240, and the buzzer 240 is connected in parallel with the standby navigation light 230.

[0050] The current relay cooperates with the main navigation light 220, the standby navigation light 230 and the buzzer 240 to realize the switching and alarm functions when the bulb of the main navigation light 220 is damaged.

[0051] Combined with Figure 2 shown, the introduction of the switching and early warning functions of the temporary navigation light bulb damage of the power failure protection and early warning device of the present utility model is as follows:

[0052] When there is no damaged bulb, the main navigation light 220 represented by S1 is powered on and emits light. When the main navigation light 220 represented by S1 is damaged, the current detection relay 210 represented by KF1 does not detect current, the current detection relay 210 operates, KF1 closes, the backup navigation light 230 represented by S2 is powered on and operates, and at the same time, the buzzer 240 represented by H1 is powered on for early warning.

[0053] As Figure 1 shown, as the power failure protection and early warning device for the temporary navigation lights of the container crane in the shipping of the present utility model, an IoT card is set in the network controller 300, and the network controller 300 is communicatively connected with the mobile terminal 600 through a wireless network.

[0054] As Figure 1 shown, as the power failure protection and early warning device for the temporary navigation lights of the container crane in the shipping of the present utility model, the network controller 300 includes a set of normally open and normally closed contacts, and the normally open and normally closed contacts have a normally open end, a normally closed end, and a common end; the common end is the first control interface and is electrically connected to the electrical output port of the uninterruptible power supply 100; the normally closed end is the second control interface and is electrically connected to the sound and light alarm 400.

[0055] As Figure 1 shown, as the power failure protection and early warning device for the temporary navigation lights of the container crane in the shipping of the present utility model, a normally open contact is arranged between the common end and the normally open end, and a normally closed contact is arranged between the common end and the normally closed end;

[0056] When the network controller 300 is powered on, the normally open contact closes and the normally closed contact opens; when the network controller 300 is powered off, the normally open contact resumes to open and the normally closed contact resumes to close.

[0057] The network controller 300 is built-in with an IoT card, is connected to the mobile phone APP of the mobile terminal 600 through a wireless network, and has a set of normally open and normally closed contacts. The live wire of the power supply of the sound and light alarm 400 is taken from the uninterruptible power supply 100 and is connected to itself through the normally closed contact of the network controller 300.

[0058] As Figure 1 shown, when the network controller 300 is powered on, it will send a reminder to the mobile phone APP of the mobile terminal 600 through a wireless network signal. At the same time, its own normally open and normally closed contacts act, the normally open ab contacts close, and the normally closed bc contacts open; when the network controller 300 is powered off, it will send a reminder to the mobile phone APP through a wireless network signal. At the same time, its own normally open and normally closed contacts act and return to the initial state, the ab contacts reconnect to open, and the bc contacts reconnect to close.

[0059] Combined with Figure 1As shown in the figure, the introduction of the power failure protection and warning function of the temporary navigation lights of the power failure protection warning device of the present utility model is as follows:

[0060] When the transport ship is normally powered, the uninterruptible power supply 100 is powered (the battery is charged), the navigation light system 200 is powered and works normally; the network controller 300 is powered, sends a reminder to the mobile phone APP of the mobile terminal 600, and at the same time the normally closed bc contact is disconnected; the audible and visual alarm 400 is connected to the uninterruptible power supply 100 through the bc contact of the network controller 300, but since the network controller 300 is powered and the normally closed bc contact has been disconnected, it is not powered and does not work.

[0061] When the power supply of the transport ship is abnormal, the uninterruptible power supply 100 loses power and its backup power supply starts. At this time, the navigation light system 200 can still work for a period of time; the network controller 300 loses power, sends a reminder to the APP of the mobile terminal 600, and at the same time the bc contact returns to normally closed; the audible and visual alarm 400 is connected to the uninterruptible power supply 100 through the normally closed bc contact, the device is powered and starts to work, giving an audible and visual warning to the ship's crew.

[0062] The power failure protection warning device of the temporary navigation lights of the container crane for shipping of the present utility model can ensure that when the power supply of the transport ship fails, the uninterruptible power supply 100 ensures that the main navigation light 220 can continue to be powered for a period of time, and the network controller 300 transmits the power failure signal to the mobile phone APP of the crew through the network for warning; at the same time, it controls the alarm to be powered and gives an audible and visual alarm.

[0063] At the same time, when the navigation light system 200 does not lose power, but does not light up due to the damage of the navigation light bulb, through the detection of the current relay, if there is no current in the bulb of the main navigation light 220, it will immediately switch to the bulb of the backup navigation light 230 to ensure that the navigation light can still emit light normally, and alarm through the buzzer 240.

[0064] The power failure protection warning device of the present utility model enables the navigation lights to give timely warnings after power failure or bulb damage, and can continue to work for a period of time to give maintenance personnel sufficient time for inspection and repair, avoiding collision accidents caused by the non - lighting of the navigation lights during this period.

[0065] The present utility model also provides a quay crane, and the quay crane includes the power failure protection warning device of the temporary navigation lights of the container crane for shipping as described above.

[0066] The power failure protection warning device of the temporary navigation lights of the container crane carried by the quay crane of the present utility model has dual software and hardware alarms. It deeply analyzes two situations that may cause the navigation lights not to light up during ship transportation and designs solutions. It can timely remind the crew of the power failure of the navigation lights, and at the same time, using the uninterruptible power supply, ensure that the navigation lights can still work during the process of crew's maintenance and troubleshooting, avoiding the occurrence of danger.
