[0002] With the acceleration of industrialization and the continuous expansion of human activities, the risk of water resources being contaminated by chemical substances is increasing. These pollutants not only pose a serious threat to the ecological environment, but also directly or indirectly affect human health and social and economic development. Therefore, it is necessary to provide early warnings for water pollution risks. When pollutants are detected or their levels increase, early warnings should be issued to upstream and downstream sources of pollutant risk transmission so that personnel can take prompt measures to reduce the extent of pollutant risk transmission and protect the environment and public health.

[0003] In water quality monitoring practice, buoy-type water quality detectors are one of the commonly used devices for monitoring the water quality of target waters. However, this type of detection device has certain limitations. Specifically, traditional buoy-type water quality detectors lack effective protection measures and are prone to capsizing when encountering external forces (such as strong winds), causing the detection probe to be exposed to the water surface or moved out of the predetermined water depth position, resulting in inaccurate data obtained, which seriously affects the accuracy and reliability of chemical water pollution risk warnings. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1 and Figure 2 A risk-transfer-based early warning device for chemical substance water pollution includes: a detection terminal located at a detection point in a flowing water area, and a plurality of early warning terminals located along a risk transmission path corresponding to the detection point. The risk transmission path refers to the upstream and downstream of the flowing water area (downstream refers to users of the water area, such as a water plant, and upstream refers to factories, such as chemical plants, whose emissions enter the flowing water area);

[0030] The detection end includes: a buoy 1, on the top wall of which are installed a processing device 2 (equivalent to a computer) and an information transmission device 3 (communication equipment for transmitting signals); on the bottom wall of the buoy 1 is installed a detection component 4, which includes a probe (a plurality of sensors are installed on the probe for detecting water quality. The device belongs to the prior art and will not be described in detail here) and a mesh cover. The mesh cover is covered on the outside of the probe to prevent large impurities from contacting the probe.

[0031] It should be noted that a photovoltaic power generation device is installed on the top of the buoy 1 to supply power to the electrical equipment on the early warning device.

[0032] See also Figure 1 and Figure 2 The buoy 1 is provided with an anti-rollover assembly; the anti-rollover assembly includes several support members and several floats 7 (air bags). The several support members are distributed in a ring shape on the outer wall of the buoy 1, and the several floats 7 are respectively installed on the end of the several support members away from the buoy 1.

[0033] A risk transfer-based early warning method for water pollution risk caused by chemical substances, the method steps are as follows:

[0034] First, place the buoy 1 in the test waters and place the detection component 4 in the water. Float 7 floats on the water surface around the buoy 1, providing support for the buoy 1. This prevents the buoy 1 from tipping over when affected by wind, and prevents the detection component from being exposed to the water surface or moving out of the predetermined area, ensuring the accuracy of the collected water quality data.

[0035] Second, the detection component 4 is in the water for collecting water quality data and transmitting the data to the processing device 2. The processing device 2 processes the collected water quality data, detects pollutants in the water, and when the content of pollutants is greater than the threshold, controls the information transmission device 3 to send information to the early warning end on the risk transmission path corresponding to the detection point to cause it to issue an alarm, so that the staff can take timely measures to prevent the spread of pollutants.

[0036] In this embodiment, as a further optimization solution, please refer to Figure 1 and Figure 2The support member is a telescopic support rod 6, which is hinged to the side wall of the buoy 1; the support member can be rotated against the side wall of the buoy 1 and retracted to reduce the space occupied by the early warning device when it is not in use.

[0037] In this embodiment, as a further optimization solution, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A mounting ring 5 is fixedly provided on the outer wall of the buoy 1, and a collar 8 is rotatably provided on the outer wall of the mounting ring 5. The telescopic support rod 6 is hinged on the outer wall of the collar 8 through a rotating shaft 13. An annular tooth is provided on the outer wall of the rotating shaft 13. A movable rack 12 is slidably provided on the collar 8 (a spring is installed between the movable rack 12 and the collar 8, and the spring is used to reset the movable rack 12). There are several movable racks 12 and they correspond to several telescopic support rods 6 one by one. The movable racks 12 are meshed with the annular teeth. Several slots 11 are provided on the outer wall of the mounting ring 5. , several slots 11 correspond to several movable racks 12 one by one, and the depth of the slots 11 gradually decreases along the rotation direction of the collar 8, and the end of the movable rack 12 away from the telescopic support rod 6 extends into the inner cavity of the slot 11; the collar 8 is rotated to make the movable rack 12 move in the inner cavity of the slot 11. As the depth of the slot 11 gradually decreases, the movable rack 12 is pushed to move gradually closer to the telescopic support rod 6. Since the annular gear and the movable rack 12 are meshed, the rotating shaft 13 will be rotated, so that the telescopic support rod 6 is rotated from a vertical direction to a horizontal state.

[0038] It should be noted that bolts are installed on the outer wall of the mounting ring 5 for fixing the rotating collar 8 .

[0039] In this embodiment, as a further optimization solution, please refer to Figure 4 The telescopic support rod 6 includes a sleeve 61, a moving rod 62 slidably inserted in the sleeve 61, an elastic member 63 (spring) provided between the sleeve 61 and the moving rod 62, and a first flexible connecting member 65 (rope, but not limited to a rope) provided between the moving rod 62 and the ring 8; a magnetic member 64 (magnet) is provided in the inner cavity of the sleeve 61, and the moving rod 62 is made of a metal material that can be magnetically adsorbed (such as iron); when the telescopic support rod 6 is rotated from a horizontal state to a vertical state, the first flexible connecting member 65 will pull the moving rod 62 into the inner cavity of the sleeve 61, thereby shortening the telescopic support rod 6; after the moving rod 62 moves into the interior of the sleeve 61, the distance between the moving rod 62 and the magnetic member 64 is reduced, and the suction force of the magnetic member 64 will act on the moving rod 62, causing the moving rod 62 to move further into the interior of the sleeve 61, thereby further reducing the length of the telescopic support rod 6.

[0040] Example 2

[0041] As a further optimization solution of Example 1, please refer to Figure 1 、 Figure 2 and Figure 5 The anti-rollover assembly also includes a number of limit members, which are arranged in a ring shape on the bottom wall of the buoy 1; the limit members include a mounting rod 10 and an umbrella-shaped barrier 9 arranged on the bottom end of the mounting rod 10; when the buoy 1 is placed on the water surface, the umbrella-shaped barrier 9 is in the water. When the buoy 1 is tilted by external force, the umbrella-shaped barrier 9 will provide a resistance to prevent the buoy 1 from further tilting, thereby reducing the chance of the buoy 1 rolling over and preventing the detection assembly 4 from being exposed to the water surface.

[0042] In this embodiment, as a further optimization solution, please refer to Figure 6 and Figure 7 The umbrella-shaped barrier 9 includes several first baffles 91 and several second baffles 92. Several first baffles 91 and several second baffles 92 are staggered to form the umbrella-shaped barrier 9. The second baffle 92 is an elastic plate (made of rubber) with certain elasticity and can be extended. When the buoy 1 tilts, part of the limiter will move upward. At this time, the downward pressure on the umbrella-shaped barrier 9 on the rising limiter will increase, causing the second baffle 92 to deform into a flat shape, increasing the lateral contact area between the umbrella-shaped barrier 9 and the water, increasing the resistance of the umbrella-shaped barrier 9 to move upward, and further reducing the probability of the buoy 1 tipping over.

[0043] In this embodiment, as a further optimization solution, please refer to Figure 6 and Figure 7 The interior of the buoy 1 is provided with a mounting groove 17, in which a plurality of counterweights 15 are slidingly provided. The counterweights 15 correspond one to one with the limit members, and the counterweights 15 are distributed in a ring shape in the inner cavity of the mounting groove 17. Elastic connecting members 16 (equivalent to rubber bands or springs) are installed between the mounting groove 17 and the counterweights 15. When the counterweights 15 move, they will approach or move away from the corresponding limit members. An opening 19 is provided through the mounting rod 10, and a movable block 18 is slidingly provided in the inner cavity of the opening 19 (the movable block 18 and the opening 19 are sealed). A second flexible connecting member 14 (which can be a rope, but is not limited to a rope) is provided between the movable block 18 and the counterweight block 15; when the limiting member is in water, the water pressure will move the movable block 18 upward, causing the counterweight block 15 to be subjected to the tension and move toward the center of the installation slot; when the buoy 1 tilts and causes part of the limiting member to move upward, the depth of the limiting member in the water decreases, causing the pressure on the movable block 18 to decrease and move downward, and the counterweight block 15 is pulled closer to this limiting member through the second flexible connecting member 14, which has a downward pressure effect, used to prevent the buoy 1 from continuing to tilt and further avoid it from tipping over.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
