Description

Technical Field

[0001] The present invention relates to the technical field of marine environmental pollutant detection, and more specifically to a pollutant detection device for marine environmental impact assessment. Background Art

[0002] The marine environment refers to the total water area of the vast and continuous seas and oceans on the earth, including seawater, substances dissolved and suspended in seawater, seabed sediments, and marine organisms. Therefore, before evaluating the marine environment, it is necessary to detect the pollution of the sea area and seawater through a special marine pollutant detection device, so as to compare the values feedback by the device with the standard environmental values to determine the environmental situation of the current sea area, and then accurately evaluate the environmental situation of the current sea area; To sum up, the inventor found that the existing detection devices mainly have the following defects: Since the current detection devices usually float on the sea surface to detect the pollution of seawater and the surrounding environment, it is impossible to control the floating distance and the stability during the floating operation detection process, making it extremely easy to collapse during the operation in the ocean due to being impacted by waves or even being lost in the ocean. Therefore, the operation stability of the pollutant detection device in the ocean is reduced; At the same time, when the monitoring device detects the quality of seawater, it is affected by some garbage in the ocean, so that the garbage will enter the device together with the seawater. Therefore, it is extremely easy for the garbage to get stuck inside the device and be difficult to remove after the seawater is detected and discharged. For this reason, the current detection device cannot avoid this phenomenon. Summary of the Invention

A card slot is opened in the center of the rotating wheel and a towing rope is also connected to the side. The towing rope passes through the side center of the positioning block and one end is also connected to a fixator.

[0011] As a further improvement of the present invention, the bottom block is set in a vertical orientation and there are two in total at the lower end of the base. The positioning block at the upper end of the base determines the position of the rotating wheel through the central rod. An outer shell is arranged outside the rotating wheel and is connected to one end of the central rod. The card slot in the center of the rotating wheel is square in shape.

[0012] As a further improvement of the present invention, the fixator is further provided with a locking groove, which is arranged at the side center of the support block and is threadedly connected to one end of the towing rope. The other end of the support block is connected to a locking block and is threadedly connected to a locking bolt.

[0014] As a further improvement of the present invention, the water quality detector is provided with an insulating housing. The top of the insulating housing is connected with an adapter block, and a detection body is also arranged in the space between the adapter blocks. A power-on block is fixed on the top of the detection body and passes through the center of the floating structure to be electrically connected with the wireless signal host.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. After the floating structure of the present invention is further improved, the four vertical columns at the lower end of the floating plate can ensure the floating balance stability of the overall device on the ocean. Then, the solid rod and the force-receiving block of the controller are used to complete the fixed connection with the dragger, so that the dragger is installed on the shore. Subsequently, the detection device can be stably placed into the ocean by manual release. According to the dragging effect, the floating distance of the detection device can be controlled, so that the floating detection process of the detection device in the ocean can be in a controllable state, thereby improving the balance stability during floating operation in the ocean.

[0019] 2. After the further improvement of the present invention by the dragger, the runner in the positioning block is positioned in the shore area of the ocean through the base and the bottom block. Then, the chuck in the center of the runner can be inserted and rotated manually by a wrench or the runner can be controlled forward and backward by the intervention of an electric rotator, so as to achieve the effect of releasing or recovering the towing rope, thus facilitating the recovery of the detection device from the ocean. Then, the towing rope can be firmly thread-connected with the support block and the locking groove of the fixator to prevent it from falling off during towing. At the same time, after the support block is embedded in one end of the solid rod, the clamping block can be embedded and locked from the other end of the solid rod by combining the convex block and the locking bolt, so as to achieve the stable towing of the overall floating structure and device, avoiding the phenomenon of tilting and collapsing into the ocean during the towing process, and improving the convenience effect of recovering the detection device.

[0020] 3. After the further improvement of the present invention by the water quality detector, the insulating housing covers the center of the lower end of the floating board and is fixed in the lower area of the floating board by the adapter block, ensuring that the detection main body can be stably inserted and electrically connected with the wireless signal host and preventing the intrusion of seawater through covering and fixing. Subsequently, the anti-drop block and the support block of the intercepting structure of the flow-through groove can determine the position of the intercepting member, so that the garbage (such as plastic bags) carried during the seawater filling process will be intercepted by the intercepting member outside, preventing the garbage from entering the flow-through groove together and contacting the detection components at the bottom of the detection main body to cause jamming. Then, the intercepted garbage can be automatically separated again following the impact of the sea waves. Description of the Drawings

Two sets are respectively provided for the locking bolt 6584 and the locking block 6583, and the centers are on the same parallel line.

[0041] The specific functions and operation procedures of this embodiment: In the present invention, the pollutant detection device for marine environmental impact assessment can generate solar power through the solar power supply body 3 on the floating structure 4, and then input the electric energy into the wireless signal host 2, so that the wireless signal host 2 can remotely control the rotating monitoring head 1 and the bottom water quality detector 5 program, so that the rotating monitoring head 1 can adjust its own monitoring direction through the bottom rotating rod, and then transmit the garbage pollution situation on the ocean to the wireless signal host 2 according to the real-time video effect, and then the water quality detector 5 at the bottom can directly contact the seawater to detect its quality, and finally transmit it to the wireless signal host 2 in the form of data, so that the wireless signal host 2 transmits the garbage pollution situation and water quality situation of the ocean in the form of wireless signals. The pollutant detection operation of the current ocean can be completed by going to the relevant judgment center, and the vertical stability of the wireless signal host 2, the rotating monitoring head 1, and the water quality monitor 5 can be maintained by the floating structure 4 during the operation to prevent the occurrence of tilting and collapse. The floating board 42 of the floating structure 4 can determine the position of the solar power supply body 3 through the upper end positioning groove 41, and then the electrical slot 43 at the lower end can allow the water quality detector 5 to be embedded and positioned, so that the water quality detector 5 can be completed by passing through the bottom center of the floating board 42 to complete the interlaced fixed electrical connection with the solar power supply body 3 and the wireless signal host 2, and then the four vertical columns 44 at the lower edge of the floating board 42 can ensure the same spacing through vertical fixation and the balance rod 45 set on the edge, so there is a vertical The cooperation of the column 44 can ensure that the floating board 42 can drift in a stable parallel state on the sea surface, and then the controller 46 equipped at one end of the balance bar 45 can overlap with it through the solid bar 463, thereby increasing its own solid hardness and positioning the force block 464. Therefore, the cooperation of the force block 464 and the solid bar 463 allows the dragger 465 to be installed and fixed, so that the detection device can be placed in the ocean. Before operation, the dragger 465 needs to be fixed on the shore, and then the solid bar 463 is connected to the balance bar 45 through the magnetic block 462 and the fixed block 461. Therefore, through the cooperation of the dragger 465, the vertical column 44 can be stably dragged by the solid bar 463 to slide in the ocean, while allowing the floating board to 42 drifts in a parallel direction to a specified direction, thereby facilitating recovery and controlling the drifting distance of the detection device, thereby improving the balance stability of the detection device during operation in the ocean, so that the base 4652 of the dragger 465 can install the positioning block 4653 on the shore through the bottom block 4651, and then the central rod 4654 inside the positioning block 4653 determines the position of the rotating wheel 4655, and then the square card slot 4656 opened in the center of the rotating wheel 4655 allows the intervention of a manual wrench or an electric rotator to control the rotating wheel 4655, so that the towing rope 4657 can be stably released or recovered according to the forward and reverse rotation of the rotating wheel 4655, thereby achieving a mechanically controllable state and improving the recovery convenience of the detection device.At the same time, the support block 6582 of the fixer 4658 at the other end of the towing rope 4657 can be threadedly connected to one end of the towing rope 4657 through the internal thread of the locking groove 6581 to prevent it from falling off during use. At the same time, the two locking blocks 6583 at the other end of the support block 6582 can allow the protrusion 6586 of the clamping block 6585 to be embedded through their own spacing. After the locking block 6583 of the support block 6582 is first embedded in the surface of the force-bearing block 464 and the solid rod 463, the clamping block 6585 is inserted from the other end with the protrusion 6586, so that the protrusion 6586 can be inserted into the spacing between the locking blocks 6583. Then, the locking bolts 6584 are locked into the locking blocks 6583 one by one to complete the fixed assembly, thereby improving the towing stability of the detection device and preventing it from falling off due to the weight of the device itself and the pressure of the ocean during the towing process. Example

[0042] Figures 6 to 7 As shown: The present invention provides a pollutant detection device for marine environmental impact assessment. Its structure includes: the water quality detector 5 is provided with an insulating shell 51, the top of the insulating shell 51 is connected to an adapter block 52, and a detection body 53 is also arranged in the interval between the adapter blocks 52, and a power block 54 is fixed on the top of the detection body 53, which passes through the center of the floating structure 4 and is electrically connected to the wireless signal host 2, and a flow groove 55 passes through the side end of the insulating shell 51 and an interception structure 56 is arranged inside the flow groove 55.

[0043] Among them, the insulating shell 51 is in the shape of a rectangular parallelepiped and is provided with two adapter blocks 52 on the top to be vertically inserted and engaged with the electrical slot 43 of the floating plate 42. An insulating frame is provided on the outside of the detection body 53 and is electrically connected to the wireless signal host 2 through the power block 54. The flow slot 55 is opened in a straight line.

[0044] The interception structure 56 is further provided with an anti-slip block 561 , which is welded to the upper center of the support block 562 and an interception member 563 is further provided at the lower end of the support block 562 to contact the seawater.

[0045] Among them, the anti-falling block 561 and the supporting block 562 are respectively provided at the upper and lower ends of the intercepting member 563 and are provided with three groups which are arranged in a horizontal direction in the flow groove 55 and allow the intercepting member 563 to intercept the flow groove 55 area horizontally.

[0046] Specific functions and operation procedures of this embodiment: In the present invention, the insulating housing 51 of the water quality detector 5 can be installed at the lower end area of the floating plate 42 through the adapter block 52. Then, through the positioning of the insulating housing 51, the detection main body 53 and the power-on block 54 can penetrate through the center of the floating plate 42 and be fixedly connected to the wireless signal host 2 in an interpenetrating manner. Furthermore, with the coverage of the insulating housing 5, seawater intrusion into the electrical connection area can be prevented. After the insulating housing 51 positions the detection main body 53 and the power-on block 54, seawater will be poured into it through the flow-through groove 55, so as to contact the detection component at the bottom of the detection main body 53. Then, the detection main body 53 can directly contact the seawater at the lower end to conduct a wide-range detection of its quality. The generated data will be transmitted to the wireless signal host 2 through electrical connection. During this process, the interception structure 56 carried by the flow-through groove 55 can position the support block 562 through the anti-disengagement block 561, so that the support block 562 installs the interception member 563. Therefore, the interception member 563 can form a mesh interception characteristic on the surface of the flow-through groove 55 in a crossed state. When seawater is poured into the flow-through groove 55, the interception member 563 can intercept the carried garbage (such as plastic bags) outside and avoid the jamming caused by the garbage entering the inside of the flow-through groove 55 and contacting the lower end of the detection main body 53 through direct contact interception. Subsequently, the intercepted plastic bags can drift to other areas again with the irregular scouring of the waves, so they cannot enter the detection device and cause jamming, which affects the overall detection accuracy.
