Description

TECHNICAL FIELD

[0001] The present application relates to the field of underwater facility monitoring, in particular to a nuclear power ocean organism interception monitoring and early warning system and method. BACKGROUND

[0002] The operation of a nuclear power plant requires a large amount of cooling water. At present, the way to obtain cooling water is to build a water intake on the coast. However, there are a large number of plankton and other sundries in the ocean. In order to ensure the safe operation of the nuclear power plant, other objects outside the water body need to be intercepted. In order to deal with the invasion of ocean objects of the nuclear power plant, the commonly used method is to set up an interception net or to remove it by manual salvage. At present, the interception net does not have a systematic interception monitoring mechanism, and it is impossible to know the interception amount in real time. If the load of the interception net is too large, it often causes damage to the net and failure of protection, which causes hidden dangers to the safe operation of the nuclear power plant.

[0003] The interception net does not have a systematic interception monitoring mechanism. Even if the blockage rate is calculated through underwater detection means, it is impossible to know the interception load in real time, it is difficult to monitor the working state of the interception net in real time, and it is also difficult to give early warning for the abnormalities occurring in the interception process. If the load of the interception net is too large, it often causes damage to the net and failure of protection, which causes hidden dangers to the safe operation of the nuclear power plant. SUMMARY

[0028] Embodiment 1

[0029] In a typical embodiment of the present application, as shown in Figures 1-2 , a nuclear power marine organism interception monitoring and early warning system is given.

[0030] like Figure 1 The nuclear power marine life interception monitoring and early warning system shown in the figure is a system in which a variety of monitoring elements are arranged on the interception net 6 when it intercepts marine life, floating garbage and other debris in the water intake area of ​​the nuclear power plant. The working status of the interception net 6 is collected, such as the interception position, the interception object situation, the bottoming status and the interception object collection status, etc. The working status of the interception net 6 is judged by using the data collected by the monitoring elements. When the collected data exceeds the parameter threshold set for the corresponding item, it is judged that its operation is abnormal and an alarm information is output in time, thereby facilitating timely adjustment of the interception net 6 and keeping the interception net 6 in a good interception working state.

[0031] like Figure 1 As shown, the nuclear power marine life interception monitoring and early warning system mainly includes an interception net 6, a sonar 3 and a bottom sensor 4. In addition, after the interception net 6 is connected to the net bag 8, a fish catch sensor 7 is also provided at the position of the net bag 8; when the interception net 6 is arranged, the interception net 6 is connected to the flexible rope used for the shore fixed structure, and a tension sensor 5 is provided. The sonar 3, the bottom sensor 4, the fish catch sensor 7 and the tension sensor 5 are all used as monitoring elements for the operation of the interception net 6, and are respectively connected to the controller 1 to send the collected information data to the controller 1.

[0032] Specifically, the interception net 6 covers the area to be intercepted to form a collecting port, and the intercepted objects enter the interception net 6 through the collecting port. The collecting port of the interception net 6 is provided with a force rod, which maintains the shape of the collecting port and can bear the force applied by the interception net 6, thereby transmitting the restraining force provided by the external fixed structure to the interception net 6.

[0033] The shape of the collection port of the interception net 6 is determined according to the shape of the area to be intercepted. For example, for the water inlet position with dams on both sides, a rectangular collection port can be used. For some water inlet positions that are transported by pipeline, a circular collection port that adapts to the pipeline cross-section can be used.

[0034] When the shape of the collecting port changes, the shape of the force network corresponding to the position of the collecting port is also adjusted. In this embodiment, a rectangular collecting port with a top and bottom parallel to the water surface is used as an example for description.

[0035] The four sides corresponding to the rectangular collecting port are distributed with force grids, or force grids can be set only at the top and bottom; the sonar 3 is installed on the force grid at the top of the collecting port, and the monitoring area of ​​the sonar 3 is covered by the interception net 6. The sonar 3 obtains the collection port height and interception object information data and sends it to the controller 1.

[0036] In this embodiment, the sonar 3 is located in the middle of the top of the collection port, and the bottom sensor 4 is located in the middle of the bottom of the collection port.

[0037] like Figure 1As shown, the sonar 3 can measure relevant information through sound wave signals, and by measuring the distance between the top force gauge and the seabed, the height position data of the collection port can be obtained. The sonar 3 continuously monitors the position of the collection port, and when the object passes through the collection port, the reflected sound wave data is obtained by the sonar 3, so as to judge the volume of the object according to the continuous time and coverage range. After the data is sent to the controller 1, the controller 1 calculates the size and volume of the related object, and compares it with the corresponding threshold value.

[0038] The bottom touch sensor 4 is installed on the force gauge corresponding to the bottom of the collection port. The bottom touch sensor 4 obtains the distance between the bottom of the collection port and the seabed and sends it to the controller 1. When the force gauge contacts the seabed, the distance data obtained by the bottom touch sensor 4 is zero. When the bottom force gauge is separated from the seabed, the distance data obtained by the bottom touch sensor 4 is a non-zero value.

[0039] Of course, it can be understood that the bottom touch sensor 4 can use an infrared sensor or other contact sensor. When the force gauge where the bottom touch sensor 4 is installed contacts the seabed, the contact sensor is triggered, so as to determine that the force gauge is well grounded. When it is separated, the contact sensor cannot be triggered, which determines that there is a gap between the force gauge and the seabed, and the bottom surface of the interception net 6 and the seabed has a gap, which is in an abnormal working state.

[0040] The sonar 3 and the bottom touch sensor 4 are connected to the controller 1 respectively. The controller 1 is used to output alarm information. After obtaining the data collected by the sonar 3 and the data collected by the bottom touch sensor 4, the controller 1 processes and analyzes such data, determines the corresponding interception information and the height information of the collection port, and can monitor whether the bottom force gauge is off the bottom.

[0041] As shown in Figure 1 For the structure of the interception net 6, one end of the interception net 6 is opened as a collection port, and the whole forms a pocket-shaped structure. After the intercepted object enters the collection port, it is blocked by the interception net 6, so as to avoid entering the cooling water area of the nuclear power plant.

[0042] The end of the interception net 6 away from the collection port is detachably connected with a net capsule 8. In the direction from the collection port to the net capsule 8, the cross-sectional area of the interception net 6 gradually decreases, forming a converging structure. After the external debris enters the interception net 6, the interception net 6 can gradually guide the external debris to the net capsule 8 under the action of the gradually changing structure, and collect them in the net capsule 8.

[0043] The fish capture sensor 7 is installed on the net bag 8, monitors the area covering the net bag 8, and is connected to the controller 1 to monitor the situation of the intercepted objects in the net bag 8, so as to prevent the intercepted objects from damaging the interception net 6 due to excessive amount. The fish capture sensor 7 in the embodiment can adopt an existing contact sensor. When the intercepted objects fill the net bag 8, the fish capture sensor 7 is contacted, and the fish capture sensor 7 sends a signal to the controller 1 after being triggered. The controller 1 determines that the net bag 8 is filled at this time, and reminds to clean the net bag 8 in time.

[0044] As shown in Figure 1 , the interception net 6 is installed on the external fixed dam or other fixed structure, and the force cable is connected with the traction cable. The traction cable is provided with the tension sensor 5, and the interception net 6 is connected to the external fixed structure through the traction cable and the tension sensor 5.

[0045] The interception net 6 is connected with multiple traction cables through the force cable. All the traction cables are arranged at intervals around the collection port, and each traction cable is provided with a corresponding tension sensor 5. The tension sensors 5 are respectively connected to the controller 1. The force condition of the interception net 6 is monitored through the tension sensors 5, and the load condition of the interception net 6 is monitored.

[0046] Multiple tension sensors 5 are adopted to cooperate with multiple traction cables. The traction cable itself also serves as the force cable of the entire interception net 6. In order to improve the monitoring precision, the traction cable is connected to multiple positions of the collection port of the interception net 6. The force state of multiple regions is monitored at multiple points to reduce the error problem caused by single-point monitoring while improving the traction bearing capacity.

[0047] As shown in Figure 1 , the controller 1 is respectively connected with the sonar 3, the bottom sensor 4, the fish capture sensor 7, and the tension sensor 5 through the cable 2. The controller 1 is arranged on the shore close to the interception net 6. In addition, the controller 1 is connected with the touch screen 9. The touch screen 9 is used to display the image data output by the controller 1 and receive external control information.

[0048] The controller 1 is arranged in the case and fixed on the shore. The cable 2 is used to power each monitoring element and collect the data obtained by each monitoring element. The touch screen 9 can also select a host with a display. The controller 1 can be wirelessly transmitted with the display and the host, and can real-time early warn the state of the interception net 6.

[0049] The state of the interception net 6 is obtained by the multiple monitoring elements arranged on or connected to the interception net 6. The force, the interception amount, and the interception effect of the interception net 6 are monitored in real time by the controller 1. The bottom of the interception net 6 can also be monitored to prevent aquatic organisms from leaking from the bottom. When the interception net 6 is in an abnormal working state, an alarm information is output to reduce the damage and protection failure of the interception net 6.

[0050] Embodiment 2

[0051] In another typical embodiment of the present application, as shown in Figures 1-2 a working method of a nuclear power ocean organism interception monitoring and early warning system is given.

[0052] The working method comprises the following steps of:

[0053] The interception net 6 is arranged so that the collection port contacts the seabed and the collection port is open;

[0054] The interception net 6 behind the collection port is kept suspended in water, the sonar 3 monitors the height of the collection port and the information data of the intercepted objects are sent to the controller 1, and the bottom sensor 4 monitors whether the bottom of the collection port is in contact with the seabed.

[0055] When the height of the collection port deviates from the set threshold, the intercepted objects passing through the collection port are abnormal, and / or the collection port is not in contact with the seabed, the controller 1 outputs an alarm information.

[0056] The sonar 3, the bottom sensor 4, the catch sensor 7 and the tension sensor 5 collect data in real time and send them to the controller 1 in real time, so as to monitor the state of the interception net 6 in real time.

[0057] By arranging the sonar 3 and the bottom sensor 4 at the position of the collection port of the interception net 6, the state of the intercepted objects of the interception net 6 is collected and the height information of the collection port is obtained at the same time, the interception state of the interception net 6 is monitored, the suspended state of the interception net 6 is monitored by the bottom sensor 4, the bottom of the interception net 6 is ensured to be in contact with the seabed, the interception net 6 can be in a reasonable working state, and the alarm information is outputted when an abnormality occurs in the monitoring, so as to achieve the purpose of early warning.

[0058] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
