Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, and in particular to a suspended water quality testing device with display function. Background Technology

[0002] A buoy-type water quality testing device is a device that uses a buoy as a carrier and integrates multiple devices such as water quality sensors, data acquisition and transmission equipment, and a power supply system. It uses water quality sensors installed at the bottom of the buoy to detect water quality. The buoy is connected to a fixed object on the shore by a rope, and the rope is used to position the buoy, thereby achieving fixed-point detection of water quality.

[0003] In practical applications, common buoy-type water quality monitoring devices typically rely on water quality sensors installed at the bottom of the buoy to detect water quality. However, these buoys are usually connected to fixed objects on the shore by ropes, and the buoys are positioned by the pull of the ropes. Consequently, water quality monitoring can only be carried out at fixed points, and the acquired water quality data often only reflects the situation at that fixed point and its limited surrounding area. It is difficult to detect water quality at different depths, resulting in significant limitations. Therefore, this application provides a suspended water quality monitoring device with display function to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a suspended water quality detection device with display function to solve the problem that common buoy-type water quality detection devices are difficult to detect water quality at different depths and have large detection limitations.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A suspended water quality testing device with display function includes:

[0007] A spherical shell, wherein a partition is fixed in the middle of the interior of the spherical shell, the partition divides the interior of the spherical shell into cavity one and cavity two, and a battery pack and a locator are respectively embedded in the wall of the spherical shell.

[0008] A flipping mechanism includes an inner sphere and a hollow shaft rotatably connected within a partition. The end of the hollow shaft is fixedly connected to the surface of the inner sphere. A servo motor is installed inside the partition and electrically connected to the battery pack. The output end of the servo motor is fixedly connected to the surface of the inner sphere. The inner sphere is located between the servo motor and the hollow shaft.

[0009] The testing mechanism includes a water pump installed inside an inner sphere, which is electrically connected to a battery pack. A hollow rotating shaft is connected to the water inlet of the water pump. The end of the hollow rotating shaft away from the inner sphere movably passes through the spherical shell and is fixed with an arc-shaped rod. A water inlet channel is opened inside the arc-shaped rod. A suction head is installed on the side of the arc-shaped rod away from the spherical shell, which is connected to the water inlet channel. The water inlet channel is connected to the hollow rotating shaft. A water supply hole is opened on the inner sphere corresponding to the water outlet of the water pump. A notch is opened on the surface of the inner sphere, and a water quality detection sensor is fixed in the notch. A drain pump is installed inside a partition. Both the water quality detection sensor and the drain pump are electrically connected to the battery pack. Two drain holes are opened on the partition corresponding to the water inlet of the drain pump. Drainage channels are opened on the side of the partition and the surface of the spherical shell.

[0010] Preferably, a groove is formed on the outer wall of the spherical shell at a location corresponding to the cavity, a flexible solar panel is adhered in the groove, the flexible solar panel is electrically connected to the battery pack, and a transparent protective shell is installed in the groove for the protection of the flexible solar panel.

[0011] Preferably, a rubber scraper is fixed to the side of the arc-shaped rod near the spherical shell.

[0012] Preferably, the center of the arc-shaped rod coincides with the center of the spherical shell.

[0013] Preferably, filter screens are embedded on both sides of the suction head, and two bent rods are installed on the outer wall of the spherical shell at a corresponding cavity. A fixing block is fixed to the end of the bent rod, and a rubber scraper is installed on the side of the fixing block.

[0014] Preferably, the side of the rubber scraper pad is provided with an inclined surface.

[0015] Preferably, a hollow circular shaft is installed on the outer wall of the spherical shell, the hollow circular shaft is connected to the drainage channel, and the arc-shaped rod is rotatably connected to the outer wall of the hollow circular shaft.

[0016] Preferably, flexible hoses are installed on opposite sides of the partition and at the corresponding drainage hole positions. The two hoses are located inside cavity one and cavity two, respectively. A counterweight head is fixed to the end of the hose away from the partition, and a small hole is opened on the outer wall of the counterweight head.

[0017] Preferably, the flexible tube is a silicone tube, and the counterweight head is made of stainless steel.

[0018] Preferably, an indicator light is installed on the outer wall of the spherical shell, and the indicator light is electrically connected to the battery pack.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above scheme, by setting up a spherical shell, an inner sphere, and a water quality detection sensor, the spherical shell floats on the water surface. The water pump is started to pump water into the second chamber. The water quality detection sensor in the second chamber detects the water sample flowing into the second chamber. At the same time, as the amount of water in the second chamber increases, the spherical shell sinks due to the weight of the water. After the water sample in the second chamber is detected, the servo motor of the flipping mechanism drives the inner sphere to rotate, so that the water supply hole turns to the first chamber. The water pump injects water into the first chamber, and the water quality detection sensor detects again, thereby realizing the detection of water quality at different depths in the river. After the detection is completed, the drainage pump empties the water in the first and second chambers, and the spherical shell floats back to the water surface and can drift with the water flow, making the detection range wider and more flexible.

[0021] With the arrangement of the arc-shaped rod and the suction head, the battery pack is placed below the second cavity. The lower half of the spherical shell is heavier than the upper half, which ensures that when the spherical shell floats on the water surface, the lower half can sink steadily in the water. This ensures that the suction head located at the bottom of the arc-shaped rod is always underwater. Even if the water surface fluctuates, it will not affect the stable extraction of water samples by the suction head, thus effectively guaranteeing the continuity and stability of water sample collection.

[0022] With the flexible solar panels installed, when the spherical shell floats on the water, the flexible solar panels are installed on the upper part of the shell. When sunlight shines on the flexible solar panels, they convert solar energy into electrical energy to charge the battery pack. At the same time, a transparent protective shell is used to protect the flexible solar panels.

[0023] With the rubber scraper installed, when the arc-shaped rod rotates upward, it drives the rubber scraper to rotate upward as well. The upward rotation of the rubber scraper automatically cleans the surface of the transparent protective shell, making the surface of the transparent protective shell cleaner and more tidy. This effectively prevents the adhesion and accumulation of impurities on the transparent protective shell, reduces the obstruction of sunlight by impurities on the transparent protective shell, and ensures the power generation capacity of the flexible solar panel.

[0024] By using a rubber scraper pad, the suction head rotates upward when the arc-shaped rod rotates upward. The filter screen on the side of the suction head contacts the rubber scraper pad at the fixed block, and the rubber scraper pad scrapes off the impurities attached to the surface of the filter screen, thereby achieving automatic cleaning of the filter screen.

Detailed Implementation

[0036] The following is a detailed description of a suspended water quality testing device with display function provided by the present invention, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0037] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0038] like Figures 1-7 As shown, an embodiment of the present invention provides a suspended water quality testing device with display function, comprising:

[0039] The spherical shell 1 has a partition 4 fixed in the middle of its interior. The partition 4 divides the interior of the spherical shell 1 into cavity 2 and cavity 3. A battery pack 28 and a locator 29 are embedded in the wall of the spherical shell 1. Both the battery pack 28 and the locator 29 are located below cavity 3. The battery pack 28 and the locator 29 are electrically connected. The spherical shell 1 serves as the main floating component of the entire device, enabling the device to float stably on the water surface and providing a basic platform for subsequent water quality testing. The locator 29 is used to position the spherical shell 1, making it easier for staff to observe the movement trajectory of the spherical shell 1 and to find the spherical shell 1 later. The battery pack 28 makes the lower half of the spherical shell 1 relatively heavy, which helps the spherical shell 1 to remain stable when floating on the water surface. Furthermore, during the subsequent filling of cavity 3 with water, it can sink smoothly as the water volume increases, enabling water quality testing at different depths.

[0040] The flipping mechanism 5 includes an inner ball 8 and a hollow shaft 7 rotatably connected within a partition 4. A sealing ring is installed inside the partition 4 for sealing between the inner ball 8 and the partition 4. The end of the hollow shaft 7 is fixedly connected to the surface of the inner ball 8. A servo motor 6 is installed inside the partition 4 and is electrically connected to the battery pack 28. The output end of the servo motor 6 is fixedly connected to the surface of the inner ball 8. The inner ball 8 is located between the servo motor 6 and the hollow shaft 7. An electromagnetic braking assembly is installed at the tail of the servo motor 6 or near the output shaft. When the servo motor 6 does not receive a rotation command, the electromagnetic braking assembly is activated, and the friction generated by the electromagnetic force tightly holds the output shaft, preventing it from rotating freely and preventing relative rotation between the ball shell 1, the partition 4, and the inner ball 8. When a rotation command is received, the electromagnetic braking assembly releases the locking of the output shaft, and the output shaft rotates normally.

[0041] The testing mechanism 9 includes a water pump 11 installed inside the inner sphere 8, which is electrically connected to the battery pack 28. A hollow rotating shaft 7 is connected to the water inlet of the water pump 11. One end of the hollow rotating shaft 7, away from the inner sphere 8, movably passes through the spherical shell 1 and is fixed with an arc-shaped rod 13. A sealing ring is embedded in the wall of the spherical shell 1, used for sealing between the spherical shell 1 and the hollow rotating shaft 7. A water inlet channel 14 is provided inside the arc-shaped rod 13. A suction head 15 is installed on the side of the arc-shaped rod 13 away from the spherical shell 1, and the suction head 15 is connected to the water inlet channel 14, which is connected to the hollow rotating shaft 7. The inner sphere 8 has a water supply hole 12 corresponding to the outlet of the water pump 11. A notch 31 is formed on the surface of the inner sphere 8, the length of which is less than the thickness of the partition 4, to prevent the connection between cavity 2 and cavity 3 at the notch 31 when the inner sphere 8 rotates. A water quality sensor 10 is fixed inside the notch 31. A drain pump 18 is installed inside the partition 4. Both the water quality sensor 10 and the drain pump 18 are electrically connected to the battery pack 28. Two drain holes are formed on the partition 4 corresponding to the inlet of the drain pump 18. These drain holes allow the cavity 2 and cavity 3 to connect with the inlet of the drain pump 18. Drainage channels 33 are provided on the side of plate 4 and the surface of spherical shell 1. Solenoid valves are installed inside plate 4 at the corresponding drainage holes. These solenoid valves are powered by battery pack 28. When drainage pump 18 starts, the solenoid valves open synchronously; when drainage pump 18 stops, the solenoid valves close synchronously. The solenoid valves prevent water from entering drainage pump 18 during water quality testing and from being discharged outwards through drainage channels 33. Spherical shell 1 floats on the water surface. Water pump 11 is started to pump water into cavity 2 3. Water quality sensor 10 in cavity 2 3 detects the water sample flowing into cavity 2 3. Simultaneously, as the amount of water in cavity 2 3 increases, spherical shell 1 sinks due to its weight. After the water sample 3 is tested, the servo motor 6 of the flipping mechanism 5 drives the inner ball 8 to rotate, causing the water supply hole 12 to rotate to cavity 2. The water pump 11 injects water into cavity 2, and the water quality sensor 10 detects again, thus realizing the detection of water quality at different depths in the river. After the detection is completed, the drainage pump 18 empties the water in cavity 2 and cavity 3, and the ball shell 1 floats back to the water surface and can drift with the water flow, making the detection range wider and more flexible. The data detected by the water quality sensor 10 is transmitted to the controller, and the wireless transmission module in the controller transmits the data to the background control system, thus realizing the data upload.

[0042] like Figure 2 and Figure 5As shown in this embodiment, a groove 25 is provided on the outer wall of the spherical shell 1 at the cavity 2. A flexible solar panel 26 is adhered in the groove 25 and electrically connected to the battery pack 28. A transparent protective shell 27 is installed in the groove 25 to protect the flexible solar panel 26. The groove 25 on the spherical shell 1 provides a suitable installation position for the flexible solar panel 26, allowing it to receive sunlight when the spherical shell 1 floats on the water surface. The flexible solar panel 26 converts solar energy into electrical energy to charge the battery pack 28, thus realizing the energy supply of the device. This greatly extends the working time of the device in an environment without an external power source and reduces maintenance costs. The transparent protective shell 27 effectively protects the flexible solar panel 26 from damage caused by external factors such as impacts from floating objects on the water surface and erosion from rainwater, ensuring the stability and durability of its power generation performance and guaranteeing the reliability of the energy supply of the entire device.

[0043] like Figures 2-4 As shown in this embodiment, a rubber scraper 17 is fixed on the side of the arc-shaped rod 13 near the spherical shell 1. When the arc-shaped rod 13 rotates upward during operation, the rubber scraper 17 rotates accordingly and contacts the transparent protective shell 27. Utilizing the softness and friction of the rubber material, it can effectively remove impurities attached to the surface of the transparent protective shell 27, preventing these impurities from attaching and blocking light, ensuring the power generation capacity of the flexible solar panel 26, and maintaining the stability of the device's energy supply.

[0044] like Figure 2 As shown, in this embodiment, the center of the arc-shaped rod 13 coincides with the center of the spherical shell 1; the concentric design makes the arc-shaped rod 13 more stable during rotation, and at the same time makes the rubber scraper 17 stably adhere to the transparent protective shell 27 when the arc-shaped rod 13 rotates.

[0045] like Figure 1 and Figure 7 As shown in this embodiment, filter screens 16 are embedded on both sides of the suction head 15. Two bent rods 21 are installed on the outer wall of the spherical shell 1 at the corresponding cavity 2. The ends of the bent rods 21 are fixed with fixing blocks 22, and rubber scraper pads 23 are installed on the sides of the fixing blocks 22. The filter screens 16 on both sides of the suction head 15 can effectively filter out large particulate impurities in the water when suctioning water samples, preventing these impurities from entering the device and clogging the water inlet channel 14, damaging key components such as the water pump 11, and ensuring the normal operation of the detection mechanism 9. When the arc rod 13 rotates upward, the suction head 15 rotates upward as well, and the filter screen 16 on its side contacts the rubber scraper pad 23 at the fixing block 22. The rubber scraper pad 23 is used to scrape off the impurities attached to the surface of the filter screen 16, realizing automatic cleaning of the filter screen 16, and further ensuring the suction efficiency and stability of the suction head 15.

[0046] like Figure 7As shown in this embodiment, the side of the rubber scraper pad 23 is provided with a bevel 24; the design of the bevel 24 makes the edges of the rubber scraper pad 23 in contact with the filter screen 16 sharper, so that when cleaning the filter screen 16, it can more comprehensively and stably scrape off the impurities on the surface of the filter screen 16, ensuring the cleaning effect of the filter screen 16.

[0047] like Figure 2 As shown in this embodiment, a hollow circular shaft 32 is installed on the outer wall of the spherical shell 1. The hollow circular shaft 32 is connected to the drainage channel 33, and the arc-shaped rod 13 is rotatably connected to the outer wall of the hollow circular shaft 32. The hollow circular shaft 32 provides a stable support structure for the rotation of the arc-shaped rod 13, ensuring that the arc-shaped rod 13 can rotate flexibly and smoothly during the process of pumping water samples and cooperating with the flipping mechanism 5. At the same time, the hollow design is connected to the drainage channel 33, which does not affect the normal operation of the drainage pump 18, making the structure of the device more compact and reasonable, and improving the space utilization rate.

[0048] like Figure 2 As shown in this embodiment, flexible hoses 19 are installed on opposite sides of the partition 4 at the corresponding drainage hole positions. The two flexible hoses 19 are located inside cavity 2 and cavity 3, respectively. A counterweight head 20 is fixed to the end of the flexible hose 19 away from the partition 4. The outer wall of the counterweight head 20 has small holes. When the spherical shell 1 tilts or rotates due to the influence of water flow, the counterweight head 20 can automatically adjust its position in cavity 2 or cavity 3 under its own weight, thereby ensuring that the drainage pump 18 can stably pump water from cavity 2 and cavity 3.

[0049] like Figure 2 As shown in this embodiment, the flexible hose 19 is a silicone tube, and the counterweight head 20 is made of stainless steel. The silicone flexible hose 19 is elastic and prevents blockage when bent by the elasticity of its own tube wall, thereby ensuring the stable suction of water from chamber 1 2 and chamber 2 3 by the drain pump 18. The stainless steel counterweight head 20 has high strength and corrosion resistance, which can improve its service life.

[0050] like Figure 1 As shown in this embodiment, an indicator light 30 is installed on the outer wall of the spherical shell 1. The indicator light 30 is electrically connected to the battery pack 28. As a visual component of the device, the indicator light 30 can flash continuously when powered by the battery pack 28, so as to facilitate the staff to observe the position of the spherical shell 1 when retrieving it, thus facilitating the retrieval of the spherical shell 1.

[0051] Working principle: The spherical shell 1 floats on the water surface and can drift with the water flow to realize water quality detection at different locations in the river. During detection, the water pump 11 is started. The water pump 11 draws water in from the suction head 15 and passes through the water inlet channel 14 and the hollow rotating shaft 7 in sequence before being discharged from the water supply hole 12 into the second cavity 3. The water quality detection sensor 10 in the second cavity 3 detects the incoming water sample. At the same time, as the amount of water in the second cavity 3 increases, the spherical shell 1 sinks under the combined action of the weight of the water in the second cavity 3 and the weight of the battery pack 28.

[0052] After the spherical shell 1 sinks and the water sample in cavity 2 3 is tested, the servo motor 6 drives the inner sphere 8 to rotate, causing the water supply hole 12 on the inner sphere 8 to rotate into cavity 1 2. The water pump 11 then runs again to inject water into cavity 1 2, and the water quality sensor 10 tests again, thus realizing comprehensive testing of water quality at different depths in the river. After the test is completed, the drainage pump 18 operates, and the water in cavity 1 2 and cavity 2 3 enters through the small hole of the counterweight head 20 and passes through the hose 19. Under the action of the drainage pump 18, the water is discharged from the hollow circular shaft 32 position at the drainage channel 33. After the water in cavity 1 2 and cavity 2 3 is discharged, the spherical shell 1 floats back to the water surface due to the reduced weight and can drift with the water flow, widening the detection range and making the detection more flexible.

[0053] A flexible solar panel 26 is attached to the groove 25 in the upper half of the spherical shell 1. When sunlight shines, it can convert solar energy into electrical energy to charge the battery pack 28. The transparent protective shell 27 in the groove 25 protects the flexible solar panel 26. When the inner sphere 8 rotates, it drives the arc rod 13 to rotate upward through the hollow rotating shaft 7. The rubber scraper 17 rotates accordingly. When the rubber scraper 17 contacts the transparent protective shell 27, it scrapes off the impurities attached to the surface of the transparent protective shell 27 to prevent the impurities from blocking the light and ensure the power generation capacity of the flexible solar panel 26.

[0054] As the arc rod 13 rotates upward, it drives the suction head 15 to rotate upward. At this time, the filter screen 16 on the side of the suction head 15 contacts the rubber scraper pad 23 on the fixing block 22 at the end of the bent rod 21. The inclined surface 24 on the side of the rubber scraper pad 23 is designed to remove impurities, realize automatic cleaning of the filter screen 16, and ensure that the suction head 15 can stably extract water samples.

[0055] After the water in chamber 2 and chamber 3 is drained, the servo motor 6 drives the inner ball 8 to rotate in the opposite direction, thereby rotating the arc rod 13 to the bottom of chamber 3, and at the same time rotating the water quality detection sensor 10 into chamber 3, waiting for the next detection.

[0056] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art will fully understand this invention even without these detailed descriptions.

[0057] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
