Description

Technical Field

[0001] This invention belongs to the field of buoy technology, specifically a buoy device for monitoring planktonic flora and fauna in waters. Background Technology

[0002] A buoy is a navigational aid that floats on the water's surface. Anchored in a designated location, it marks the extent of a navigational channel, indicates shoals, obstructions, or serves a specific purpose. Buoys are the most numerous and widely used type of navigational aid, placed in locations where it is difficult or unsuitable to establish fixed navigational markers. The function of a buoy is to mark shallow channels or obstacles that endanger navigational safety. Buoys equipped with lights are called light buoys, and those used as signal buoys in navigable waters day and night are used for navigational assistance. Some buoys are also equipped with radar transponders, radio beacons, fog warning signals, and marine survey instruments.

[0003] Current buoys are designed for navigational safety and have a relatively limited function. They cannot monitor planktonic plants and animals while floating, nor can they move freely in the water. They are also prone to damage in case of collisions. Summary of the Invention

[0020] like Figure 1-8As shown, this invention provides a buoy device for monitoring planktonic flora and fauna in waters. The components of the device are made of pressure-resistant materials, and the materials used in the device are made of corrosion-resistant materials. The device includes a buoy 1, which is made of metal. The buoy 1 contains a control processor with a corresponding control program. The control processor is signal-connected to the electrical control components in the device, and performs corresponding signal processing and transmission. A monitoring box 32 is connected to the buoy 1 via a lifting mechanism. The lifting mechanism is used to move the monitoring box 32 up and down, facilitating the adjustment of the depth and height of the monitoring box 32. The monitoring box 32 is also made of metal. The monitoring box 32 is equipped with a phytoplankton density measuring mechanism for measuring the density of phytoplankton. This mechanism includes a measuring chamber 37 within the monitoring box 32. A supporting shaft 51, made of metal, is rotatably connected to the end wall of the measuring chamber 37 and is powered by a measuring motor fixedly installed inside the monitoring box 32. A supporting plate 50, also made of metal, is fixedly mounted on the outer surface of the supporting shaft 51 and has filter holes. An electronic scale 52 is fixedly connected to the upper surface of the supporting plate 50 for weighing the phytoplankton. The weighing process includes a filter plate 53 fixedly connected to the upper end of the electronic scale 52. The filter plate 53 is made of metal and is used for filtering water, allowing water to pass through. Elastic sealing plates 54, made of rubber, are fixedly connected to both ends of the filter plate 53. These elastic sealing plates 54 seal the edges of the filter plate 53 to prevent leakage and facilitate rotation. A water collection tank 40 is fixedly connected to the bottom wall of the measuring chamber 37. The water collection tank 40 is made of metal and is used to collect the filtered water.

The outer surface of the mounting plates 14 is covered with a wear-resistant material. A rotating shaft 17, also made of metal and with a wear-resistant material on its outer surface, is fixedly mounted on the inner surface of the mounting plates 14. The rotating shaft 17 is connected to an adjusting motor, which is fixedly mounted inside the mounting plates 14. A fixing ring 16 is fixedly mounted between the rotating shafts 17. The upper edge of the water collection tank 40 is tightly attached to the end wall of the measuring chamber 37. A drain pump 22 is fixedly mounted on the bottom wall of the tank 40. The extraction pump 41 is activated, allowing planktonic plants and water to enter the measuring chamber 37 through the extraction pipe 15, the extraction pipe, the suction pipe 21, and the extraction pump 41. The water then falls onto the filter plate 53, passes through the filter plate 53 and the support plate 50, and enters the water collection tank 40 for collection. The liquid level monitoring sensor 39 measures the liquid level in the water collection tank 40, and the electronic scale 52 measures the weight of the planktonic plants on the filter plate 53. The density of the planktonic plants is calculated using the measured water volume and the weight of the planktonic plants. The drain pump 22 discharges the water from the water collection tank 40. When cleaning the filter plate 53 is required, the measuring motor is activated, causing the support shaft 51 to rotate, which in turn rotates the support plate 50, thus rotating the filter plate 53 by a certain angle to clean its surface.

[0021] Advantageously, an auxiliary filtration mechanism is provided on the upper end wall of the measuring cavity 37. This auxiliary filtration mechanism is used to dehydrate auxiliary planktonic plants and animals, facilitating accurate weight acquisition.

An auxiliary dehydration plate 49 is fixedly connected to the lower end of the dehydration electric push rod 48. The auxiliary dehydration plate 49 is made of a metal material and has a wear-resistant material on its outer surface. The radius of the auxiliary dehydration plate 49 is the same as the radius of the channel 46. The two auxiliary dehydration plates 49 are located in the channel 46 and form a closure of the channel 46. This energizes the auxiliary electric lead screw 44, causing it to rotate. The auxiliary electric lead screw 44 is threadedly connected to the nut plate 47, which in turn moves the nut plate 47, thereby moving the dehydration electric push rod 48 and the auxiliary dehydration plate 49. When the auxiliary dehydration plate 49 moves into the channel 46, the dehydration electric push rod 48 is energized, causing the auxiliary dehydration plate 49 to move downwards until it is flush with the bottom surface of the dehydration frame 61. The pressing electric push rod 43 is energized, causing the dehydration frame 61 to move downwards and contact the planktonic plants on the filter plate 53, pressing out the water from the planktonic plants. The water then passes through the filter plate 53, the support plate 50, and is collected in the water collection tank 40.

[0022] Advantageously, a cleaning mechanism is provided on the end wall of the measuring cavity 37. This cleaning mechanism is used to clean the surface of the filter plate 53.

The baffle 35 is made of metal and is sealed with the connecting groove 33. The monitoring box 32 is provided with a collection chamber 31, which is connected to the connecting groove 33. This energizes the cleaning screw 60, causing it to rotate. The cleaning screw 60 is threadedly connected to the cleaning nut block 62, which in turn moves the cleaning nut block 62, thereby moving the connecting plate 58, which in turn moves the cleaning electric push rod 56, which in turn moves the cleaning plate 55. This pushes the planktonic plants on the upper side of the filter plate 53 to contact the baffle 35, causing the damping shaft 34 to rotate. This allows the planktonic plants to enter the collection chamber 31 for collection. When the cleaning nut block 62 reaches its limit position, the cleaning electric push rod 56 is energized, causing the cleaning plate 55 to move, facilitating the pushing of planktonic plants into the collection chamber 31. After completion, the baffle 35 is automatically reset by the damping shaft 34.

The motion motor is activated, which drives the motion shaft 5 to rotate, which in turn drives the propeller 6 to rotate, which in turn drives the float 2 to move, which in turn drives the buoy 1 to move in the water.

The cleaning nozzle 36 is connected to the cleaning pump 38 through a water supply pipe. The cleaning pump 38 is fixedly installed on the bottom wall of the measuring chamber 37 inside the water collection tank 40. The cleaning pump 38 is then activated, which draws water from the water collection tank 40 and delivers it through the water pipe to the cleaning nozzle 36.

The monitoring camera 12 sends a signal to the control processor, and the control processor sends a signal to the corresponding components, which facilitates the adjustment of the position of the buoy 1.

[0029] In the working process of this invention, the electrical energy generated by the photovoltaic panel 8 enters the storage battery through the transmission line, and after being inverted by the photovoltaic inverter, it supplies power to the electrical components in the device. The monitoring camera 12 sends a signal to the control processor, and the control processor sends a signal to the corresponding components to facilitate the adjustment of the position of the buoy 1. The moving motor is started, thereby driving the gear shaft 28 to rotate, which in turn drives the gear 27 to rotate. The gear 27 meshes with the rack, thereby driving the float 2 to rotate, which in turn drives the fixed plate 3 to rotate to the corresponding position. The motion motor is started, thereby driving the motion shaft 5 to rotate, which in turn drives the propeller 6 to rotate, thus... The movement of the float plate 2 causes the buoy 1 to move in the water. When a turn is needed, the steering motor is activated, which rotates the steering shaft 19, which in turn rotates the bogie 4, which in turn rotates the propeller 6, thus achieving a turn. Upon impact, the propeller contacts the anti-collision block 10, compressing the spring rod 9 for anti-collision protection. The lifting motor is activated, which rotates the lifting shaft 25, which in turn rotates the winding drum 24, causing the wire rope 20 to move, which in turn moves the monitoring box 32 to adjust its height. When a descent is needed, the water inlet valve is opened, allowing water to enter the buoyancy ball 1. In step 3, the monitoring box 32 sinks. When it floats, the drain valve opens, causing the monitoring box 32 to float. The extraction pump 41 is activated, allowing planktonic plants and water to enter the measuring chamber 37 through the extraction pipe head 15, the extraction pipe, the suction pipe head 21, and the extraction pump 41. The water then falls onto the filter plate 53. The auxiliary electric screw 44 is energized, causing it to rotate. The auxiliary electric screw 44 is threadedly connected to the nut plate 47, which in turn moves the nut plate 47, thereby moving the dehydration electric push rod 48 and the auxiliary dehydration plate 49. When the auxiliary dehydration plate 49 moves into the channel 46... When the dehydration electric push rod 48 is energized, it drives the auxiliary dehydration plate 49 to move downwards until it is flush with the bottom surface of the dehydration frame 61. When the pressing electric push rod 43 is energized, it drives the dehydration frame 61 to move downwards and contact the planktonic plants on the filter plate 53, pressing out the water from the planktonic plants. The water then passes through the filter plate 53, the support plate 50, and enters the water collection tank 40 for collection. The liquid level monitoring sensor 39 measures the liquid level in the water collection tank 40, and the electronic scale 52 measures the weight of the planktonic plants on the upper side of the filter plate 53.The density of phytoplankton is calculated by measuring the volume of water and the weight of the phytoplankton. After measurement, the cleaning screw 60 is energized, causing it to rotate. The cleaning screw 60 is threadedly connected to the cleaning nut block 62, which in turn moves the connecting plate 58, which in turn moves the cleaning electric push rod 56, which in turn moves the cleaning plate 55. This pushes the phytoplankton on the upper side of the filter plate 53 to contact the baffle 35, causing the damping shaft 34 to rotate. This allows the phytoplankton to enter the collection chamber 31 for collection. When the cleaning nut block 62 reaches its limit position, the cleaning electric push rod 56 is energized. This causes the cleaning plate 55 to move, facilitating the pushing of planktonic plants and animals into the collection chamber 31. After completion, it resets, and the damping shaft 34 automatically drives the baffle 35 to reset. When the filter plate 53 needs cleaning, the measuring motor is started, which drives the support shaft 51 to rotate, thereby driving the support plate 50 to rotate, and thus driving the filter plate 53 to rotate a certain angle to clean the surface of the filter plate 53. The cleaning pump 38 is started, which draws water from the water collection tank 40 and delivers it through the water pipe to the cleaning nozzle 36. The water is then sprayed onto the filter plate 53 through the cleaning nozzle 36 to clean the surface of the filter plate 53. After cleaning, the drain pump 22 discharges the water from the water collection tank 40.
