Description

Technical area

[0001] The present invention relates to the technical field of flotsam barriers and in particular to a monitoring system for a flotsam barrier. Background technology

[0002] Floating debris booms are typically installed in dam areas that float on the water surface. Due to the long distance, they are not suitable for inspection. The individual groups of floating debris booms are connected by a pin shaft. During operation, factors such as rust and long-term friction can cause wear of the pin shaft, which may lead to jamming of the floating debris boom. When the water level in the dam area changes drastically, a floating debris boom will remain stuck at the position where the pin shaft is stuck, preventing it from moving with the water level. If the floating debris boom is stuck for a long time and is not treated in time, the water level will continue to rise, which may cause the floating debris boom as a whole to topple over, the joint to break, or other problems occur.Part of the debris barrier enters the spiral with the water flow and gets stuck in the turbine's guide vane, which can lead to an accident. Content of the invention

[0003] The aim of the present invention is to solve at least partially one of the technical problems of the prior art.

[0004] To this end, an embodiment of the present invention proposes a monitoring system for a debris barrier that enables real-time monitoring of the debris barrier. When the debris barrier becomes stuck, an alarm sounds to remind personnel to take timely action, thereby reducing the risk of a variety of accidents, such as the debris barrier completely tipping over, the joint breaking, and the turbine jamming.

[0005] A monitoring system for a flotsam barrier according to the embodiment of the present invention comprises a level meter and an alarm device, wherein the level meter is connected to the flotsam barrier and the alarm device is connected to the level meter in a signal connection.

[0006] In some embodiments, the level gauge is movably connected to the flotsam barrier along a vertical direction.

[0007] In some embodiments, the level gauge is surrounded by a protective cylinder, wherein the protective cylinder is movably connected to the flotsam barrier.

[0008] In some embodiments, the flotsam barrier comprises a plurality of floats and the number of level gauges is a plurality, wherein at least two of the level gauges are connected to different floats.

[0009] In some embodiments, at least two of the level meters are signal-connected to the alarm device.

[0010] In some embodiments, it further comprises a battery, wherein at least one of the level meter and the alarm device is electrically connected to the battery.

[0011] In some embodiments, it further comprises a solar panel, wherein the solar panel is electrically connected to the battery.

[0012] In some embodiments, it further comprises a control box, wherein the control box is connected to the flotsam barrier and the battery is arranged in the control box.

[0013] In some embodiments, it further comprises a support frame, wherein the support frame is connected to the flotsam barrier, and wherein at least one of the control box and the level gauge is connected to the support frame.

[0014] In some embodiments, the control box is located on top of the support frame and the solar panel and the alarm device are both located on top of the control box.

[0015] In the monitoring system for a flotsam and jetsam barrier of the embodiment of the present invention, the water level gauge can detect the depth of the flotsam and jetsam barrier by placing the water level gauge on the flotsam and transmit the detected water level signal to the alarm device. The alarm device can trigger an alarm based on the received water level signal when the flotsam and jetsam barrier becomes stuck, thereby realizing real-time monitoring of the flotsam and jetsam barrier.

[0016] In particular, when the flotsam and jetsam barrier is working normally, it will rise or fall with the change of water level, and the draft of the flotsam and jetsam barrier remains within the standard draft range, and the water level detected by the level gauge also remains within the preset water level range; when the flotsam and jetsam barrier is stuck, its water level cannot rise or fall with the change of water level. At this time, the water level detected by the level gauge exceeds the preset water level range. The alarm device receives the water level signal and then sends out an alarm signal to remind personnel that the flotsam and jetsam barrier is stuck, so that the problem can be dealt with in time, thereby reducing the risk of a series of accidents such as the flotsam and jetsam barrier completely overturning, the joint breaking, and the turbine blocking.

Specific embodiments

[0018] The embodiments of the present invention are described in detail below. The embodiments described below with reference to the accompanying drawings are exemplary and serve to explain the present invention and are not to be understood as limiting the present invention.

[0019] As in Fig. 1, the monitoring system 100 for a flotsam barrier comprises a level meter 1 and an alarm device 2, wherein the level meter 1 is connected to the flotsam barrier and the alarm device 2 is connected to the level meter 1 in a signal connection.

[0020] In the monitoring system 100 for a flotsam and jetsam barrier of the embodiment of the present invention, the water level gauge 1 can detect the draft of the flotsam and jetsam barrier by placing the water level gauge 1 on the flotsam and transmit the detected water level signal to the alarm device 2. The alarm device 2 can trigger an alarm based on the received water level signal when the flotsam and jetsam barrier is stuck, thereby realizing real-time monitoring of the flotsam and jetsam barrier.

[0021] Specifically, when the debris barrier is operating normally, it will rise or fall with the change of water level, and the draft of the debris barrier remains within the standard draft range, and the water level detected by the level gauge 1 also remains within the preset water level range; when the debris barrier is stuck, its water level cannot rise or fall with the change of water level. At this time, the water level detected by the level gauge 1 exceeds the preset water level range. The alarm device 2 receives the water level signal and then sends out an alarm signal to remind personnel that the debris barrier is stuck, so that the problem can be dealt with in time, thereby reducing the risk of a series of accidents such as the complete overturning of the debris barrier, the breakage of the joint, and the blocking of the turbine.

[0022] Optionally, the level meter 1 is an electrode type level meter 1.

[0023] The electrode type level meter 1 has the advantages of high measurement accuracy, wide application range, convenient operation, low maintenance cost, etc., and can achieve better monitoring effect.

[0024] Optionally, alarm device 2 is a sound and light alarm device 2.

[0025] Since the debris barrier is installed in a distant dam area, a more intuitive alarm signal can be issued via the sound and light alarm device 2, which makes it easier for personnel to detect the alarm signal.

[0026] In some embodiments, as in the Fig. 1 and Fig. As shown in Figure 2, the level gauge 1 is connected to the flotsam barrier so that it can move vertically.

[0027] By arranging as above, the water level gauge 1 can be adjusted up and down according to the on-site conditions, so that the preset water level range of the water level gauge 1 corresponds to the standard draught range of the flotsam and jetsam, so that the draught depth of the flotsam and jetsam can be accurately measured by the water level gauge 1, and then an alarm signal can be issued when the draught depth of the flotsam and jetsam exceeds the standard draught range.

[0028] In some embodiments, as in Fig. 3, the level gauge 1 is surrounded by a protective cylinder 11, wherein the protective cylinder 11 is movably connected to the flotsam barrier.

[0029] The debris barrier is designed to catch floating debris on the water surface. At high water flow velocities, some of the debris will hit the debris barrier, which can easily damage the level gauge 1. By installing the protective cylinder 11, the level gauge 1 can be protected and its service life extended.

[0030] As an example, as in Fig. 3, the protective cylinder 11 is placed externally on the level gauge 1, and a mounting sleeve 12 is slipped onto the protective cylinder 11. The protective cylinder 11 is slidably connected to the mounting sleeve 12. The mounting sleeve 12 is provided with a locking bolt 131. The locking bolt 131 is connected to the mounting sleeve 12 by a thread and rests against the outside of the protective cylinder 11. The locking bolt 131 can fix the protective cylinder 11. A mounting plate 13 is firmly connected to one side of the mounting sleeve 12, and an end of the mounting plate 13 remote from the mounting sleeve 12 is connected to the flotsam barrier. The level gauge 1 is arranged laterally on the flotsam barrier and has a certain distance from the flotsam barrier so that the level gauge 1 can contact the water surface of the damming area.

[0031] In some embodiments, the flotsam barrier comprises a plurality of floats and the number of level gauges 1 is several, wherein at least two of the level gauges 1 are connected to different floats and at least two of the level gauges 1 are in signal connection with the alarm device 2.

[0032] In the event of strong waves on the water surface, the debris barrier may tilt, resulting in one side of the debris barrier having a greater draft and the other side having a lesser draft. This, in turn, causes the water level detected by level gauge 1 to exceed the preset water level range and trigger a false alarm.

[0033] By arranging multiple water level gauges 1 and connecting the signals of the multiple water level gauges 1 to the same alarm device 2, the alarm device 2 can receive water level signals from multiple water level gauges 1; when the water levels detected by multiple water level gauges 1 exceed the preset water level range, the alarm device 2 activates the alarm, thereby reducing the probability of false alarms from the alarm device 2.

[0034] In addition, the level gauges 1 can each be arranged at different positions on the same float, thereby further reducing the likelihood of false alarms from the alarm device 2.

[0035] In some embodiments, the flotsam and jetsam monitoring system 100 further comprises a battery, wherein at least one of the level gauge 1 and the alarm device 2 is electrically connected to the battery.

[0036] Since the flotsam barrier monitoring system 100 is installed on the flotsam barrier and the flotsam barrier is installed in a remote dam area, the power supply of the flotsam barrier monitoring system 100 on the flotsam barrier is relatively cumbersome.

[0037] By arranging a storage battery, the battery can supply power to the level meter 1 and the alarm device 2, thereby solving the power supply problem of the flotsam and jetsam monitoring system 100.

[0038] Optionally, the level meter 1 and the alarm device 2 are both electrically connected to a battery.

[0039] Optionally, the standard battery voltage is 24V.

[0040] In some embodiments, as in Fig. 1, the flotsam barrier monitoring system 100 further comprises a solar panel 3, wherein the solar panel 3 is electrically connected to the battery.

[0041] By arranging the solar panel 3, the electrical energy generated by the solar panel 3 can be stored in the battery, thereby achieving power independence for the flotsam and jetsam monitoring system 100. At the same time, the solar panel 3 has a long service life, requires less daily maintenance, and can maintain efficient operation, thereby keeping the maintenance costs of the flotsam and jetsam monitoring system 100 low.

[0042] In some embodiments, as in Fig. 1, the monitoring system 100 for a flotsam barrier further comprises a control box 4, wherein the control box 4 is connected to the flotsam barrier and the battery is arranged in the control box 4.

[0043] The control box 4 can protect the battery and prevent damage from debris trapped by the debris barrier. At the same time, it can prevent the battery from being directly immersed in water and damaged if the debris barrier gets stuck and the water surface submerges it.

[0044] In addition, the connecting parts between the alarm device 2, the level meter 1, etc. and the battery are also arranged in the control box 4, which can protect the wiring parts.

[0045] Optionally, the control box 4 has a sealed cavity, and the battery and the above-mentioned wiring parts are installed in this cavity. The control box 4 has a through-hole on its wall, and the connecting cables between the battery and the solar panel 3, the connecting cables between the level meter 1 and the battery, etc., pass through this through-hole, and the through-hole is waterproof.

[0046] As an example, as in Fig. 1, the external dimensions of the control box 4 are: length 300 mm, width 200 mm, height 300 mm.

[0047] In some embodiments, as in the Fig. 1 and Fig. 2, the flotsam boom monitoring system 100 further comprises a support frame, the support frame being connected to the flotsam boom, and at least one of the control box 4 and the level gauge 1 being connected to the support frame.

[0048] By arranging as above, the control box 4, the level meter 1, the solar panel 3, the alarm device 2, and other devices of the floating debris barrier monitoring system 100 can be assembled with the support frame. The support frame can then be connected to the floating debris barrier, simplifying installation.

[0049] As an example, as in Fig. 1 and Fig. 2, there are two types of support frames, namely a first support frame 51 and a second support frame 52, and both the first support frame 51 and the second support frame 52 are made of stainless steel.

[0050] As in Fig. As shown in Figure 1, the first support frame 51 is configured to support the control box 4, the solar panel 3, the alarm device 2, the level meter 1, and other devices. The first support frame 51 includes a rectangular first platform 511 and four first support legs 512 arranged at the bottom of the first platform 511. The table size of the first platform 511 is: length 400mm, width 300mm, the four first support legs 512 are distributed in two rows and two columns at the bottom of the first platform 511, and all are welded and fixed to the first platform 511.The lower end of the first support legs 512 is firmly connected to the protective cylinder 11 of the flotsam and jetsam barrier by bolts; the control box 4, the solar panel 3, the alarm device 2, and other devices are arranged on the top of the first platform 511, and the level gauge 1 is connected to one side of the first platform 511 via the mounting plate 13 on its outer side, thereby realizing the stable installation of the flotsam and jetsam barrier monitoring system 100.

[0051] As in Fig.2, the second support frame 52 is a triangular support mainly designed to support the level meter 1; the second support frame 52 includes a circular second platform 521 and three second support legs 522 arranged on the underside of the second platform 521, the three second support legs 522 are all welded and fixed to the second platform 521, and the lower end of the second support legs 522 is further firmly connected to the protective cylinder 11 of the flotsam and jetsam barrier by bolts; the level meter 1 is firmly connected to the second platform 521 via the mounting plate 13 on its outer side, so that stable installation of the level meter 1 can be realized.

[0052] In addition, the second platform 521 has the same height as the first platform 511, so that the heights of the level meters 1 are the same.

[0053] In some embodiments, the control box 4 is arranged on top of the support frame and the solar panel 3 and the alarm device 2 are both arranged on top of the control box 4.

[0054] Since the volume of the debris barrier float is limited, the available installation area above it is also limited; by adopting an upper and lower arrangement installation method for the debris barrier monitoring system 100, the occupied area of ​​the debris barrier monitoring system 100 can be reduced, which better promotes the connection between the support frame and the debris barrier float, and improves the stability of the connection between the debris barrier monitoring system 100 and the debris barrier.

[0055] By arranging the control box 4 on top of the support frame, the distance between the control box 4 and the debris barrier can be increased, thereby increasing the distance between the control box 4 and the water surface and reducing the risk of the control box 4 being submerged in the water.

[0056] By placing the solar panel 3 and the alarm device 2 on top of the control box 4, the solar panel 3 can fully receive sunlight, thereby improving power generation efficiency. At the same time, the alarm device 2 is placed on top of the control box 4. When the alarm device 2 issues an alarm signal, it is easier to attract the attention of personnel to timely resolve the blockage of the debris barrier, preventing the debris barrier from tipping over completely and breaking the joint.
