Description

Technical Field

[0001] The invention relates to the technical field of water quality detection, and in particular to a suspended water quality detection device with a display function. Background Art

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

[0003] In actual use, common buoy-type water quality detection devices usually rely on water quality detection sensors installed at the bottom of the buoy to achieve the purpose of detecting water quality conditions. However, the buoy is generally connected to a fixed object on the shore with the help of a rope, and the buoy is positioned by the pulling action of the rope. Therefore, water quality detection can only be carried out at a fixed point, so the water quality data obtained can often only reflect the situation within a limited range of the fixed point and its surroundings. It is difficult to detect water quality at different depths, and the detection limitations are large. Therefore, the present application provides a suspended water quality detection device with a display function to meet the needs. Summary of the invention

[0012] Preferably, hoses are installed on opposite sides of the partition and corresponding to the drainage holes. The two hoses are respectively located inside cavity one and cavity two. A counterweight head is fixed to one end of the hose away from the partition, and a small hole is opened on the outer wall of the counterweight head.

[0013] Preferably, the hose is a silicone tube and the counterweight head is made of stainless steel.

[0014] 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.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, through the arrangement of the spherical shell, the inner sphere and the water quality detection sensor, the spherical shell floats on the water surface, the water pump is started to pump water to the second chamber, and 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 is turned 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 channel.

Even if the water surface fluctuates, it will not affect the stable extraction of water samples by the suction head, which effectively guarantees the continuity and stability of the water sample collection work.

[0017] Through the setting of flexible solar panels, when the spherical shell floats on the water, the flexible solar panels are installed on the upper part of the spherical shell. When sunlight shines on the flexible solar panels, the flexible solar panels convert solar energy into electrical energy to charge the battery pack. At the same time, the flexible solar panels are protected by a transparent protective shell.

[0018] Through the setting of the rubber scraper, when the arc rod rotates upward, it drives the rubber scraper to rotate upward. The upward rotation of the rubber scraper realizes automatic cleaning of the surface of the transparent protective shell, making the surface of the transparent protective shell cleaner and tidier, effectively preventing the adhesion and accumulation of impurities on the transparent protective shell, reducing the obstruction of impurities on the transparent protective shell to sunlight, and ensuring the power generation capacity of the flexible solar cell panel.

[0019] Through the setting of the rubber scraper pad, when the arc rod rotates upward, the suction head is driven to rotate upward, and the filter on the side of the suction head contacts the rubber scraper pad at the fixed block. The rubber scraper pad is used to scrape off impurities attached to the surface of the filter, thereby realizing automatic cleaning of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides a suspended water quality detection device with a display function, comprising: The spherical shell 1 has a partition 4 fixed in the middle of the spherical shell 1. The partition 4 divides the interior of the spherical shell 1 and forms a cavity 1 2 and a cavity 2 3. A battery pack 28 and a positioner 29 are respectively embedded in the wall thickness of the spherical shell 1. The battery pack 28 and the positioner 29 are both located below the cavity 2 3. The battery pack 28 is electrically connected to the positioner 29. The spherical shell 1 serves as the main floating component of the entire device, so that the device can stably float on the water surface, providing a basic platform for subsequent water quality detection work. The positioner 29 is used to locate the spherical shell 1, which is convenient for the staff to observe the movement trajectory of the spherical shell 1 and facilitate the subsequent search for the spherical shell 1. The battery pack 28 makes the lower half of the spherical shell 1 relatively heavy, which is conducive to the stability of the spherical shell 1 when floating on the water surface. In the subsequent water filling process of the cavity 2 3, it can sink steadily as the water volume increases, realizing water quality detection at different depths; The flipping mechanism 5 includes an inner sphere 8 and a hollow shaft 7 which are rotatably connected in the partition 4. A sealing ring is installed in the partition 4 for sealing between the inner sphere 8 and the partition 4. The end of the hollow shaft 7 is fixedly connected to the surface of the inner sphere 8. A servo motor 6 is installed in the partition 4. The servo motor 6 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 sphere 8. The inner sphere 8 is located between the servo motor 6 and the hollow shaft 7. An electromagnetic brake 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 brake assembly is started, and the friction force generated by the electromagnetic force tightly holds the output shaft to prevent it from rotating freely, thereby preventing the ball shell 1 and the partition 4 from rotating relative to the inner sphere 8. When the rotation command is received, the electromagnetic brake assembly releases the lock on the output shaft, and the output shaft rotates normally at this time; The detection mechanism 9 includes a water pump 11 installed in the inner sphere 8, the water pump 11 is electrically connected to the battery pack 28, the hollow shaft 7 is connected to the water inlet of the water pump 11, the end of the hollow shaft 7 away from the inner sphere 8 movably penetrates the spherical shell 1 and is fixed with an arc rod 13, a sealing ring is embedded in the wall thickness of the spherical shell 1, the sealing ring is used for sealing between the spherical shell 1 and the hollow shaft 7, a water inlet channel 14 is opened inside the arc rod 13, a suction head 15 is installed on the side of the arc rod 13 away from the spherical shell 1, the suction head 15 is connected to the water inlet channel 14, and the water inlet channel 14 is connected to the hollow shaft 7 A water supply hole 12 is provided on the inner sphere 8 at the water outlet corresponding to the water pump 11, a notch 31 is provided on the surface of the inner sphere 8, the length of the notch 31 is less than the thickness of the partition 4, to prevent the situation where the cavity 1 2 and the cavity 2 3 are connected at the notch 31 when the inner sphere 8 rotates, a water quality detection sensor 10 is fixed in the notch 31, a drainage pump 18 is installed in the partition 4, the water quality detection sensor 10 and the drainage pump 18 are both electrically connected to the battery pack 28, and two drainage holes are provided on the partition 4 at the water inlet corresponding to the drainage pump 18, the drainage holes are used for the connection between the cavity 1 2 and the cavity 2 3 and the water inlet on the drainage pump 18, and the partition Drainage channels 33 are provided on the side of the plate 4 and the surface of the spherical shell 1. A solenoid valve is installed at the corresponding drainage hole inside the partition 4. The solenoid valve is powered by the battery pack 28. The solenoid valve is opened synchronously when the drainage pump 18 is started, and is closed synchronously when the drainage pump 18 is closed. The solenoid valve is used to prevent water from entering the drainage pump 18 and being discharged from the drainage channel 33 during the water quality detection process. The spherical shell 1 floats on the water surface, and the water pump 11 is started to pump water into the cavity 2 3. The water quality detection sensor 10 in the cavity 2 3 detects the water sample flowing into the cavity 2 3. At the same time, as the amount of water in the cavity 2 3 increases, the spherical shell 1 sinks due to the weight of the water, and the cavity 2 3 is filled with water. After the water sample 23 is tested, the servo motor 6 of the flip mechanism 5 drives the inner sphere 8 to rotate, so that the water supply hole 12 turns to cavity 1 2, and the water pump 11 injects water into cavity 1 2. The water quality detection sensor 10 detects again, thereby realizing the detection of water quality at different depths in the river channel. After the detection is completed, the drainage pump 18 drains the water in cavity 1 2 and cavity 2 3, and the ball shell 1 floats back to the water surface and can float with the water flow. The detection range is wider and more flexible. The data detected by the water quality detection sensor 10 is transmitted to the controller, and the wireless transmission module in the controller is used to transmit the data to the background control system, thereby realizing data upload.

[0027] like Figure 2 and Figure 5As shown, in this embodiment, a groove 25 is opened at the outer wall of the spherical shell 1 corresponding to the cavity 1-2, and a flexible solar panel 26 is adhered in the groove 25, and the flexible solar panel 26 is electrically connected to the battery pack 28. A transparent protective shell 27 is installed in the groove 25, and the transparent protective shell 27 is used 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, so that when the spherical shell 1 floats on the water, it can receive sunlight. The flexible solar panel 26 converts solar energy into electrical energy to charge the battery pack 28, realizing the energy supply of the device, greatly extending the working time of the device in an environment without an external power supply, and reducing the maintenance cost. The transparent protective shell 27 effectively protects the flexible solar panel 26 from damage by external factors such as impact of floating objects on the water surface and erosion by rain, ensuring the stability and durability of its power generation performance and the reliability of the energy supply of the entire device.

[0028] like Figure 2-Figure 4 As shown, in the present embodiment, a rubber scraper 17 is fixed to one side of the arc rod 13 close to the spherical shell 1; when the arc rod 13 rotates upward during operation, the rubber scraper 17 rotates accordingly, and contacts the transparent protective shell 27. By utilizing the softness and friction of the rubber material, the impurities attached to the surface of the transparent protective shell 27 can be effectively removed to prevent these impurities from adhering to and blocking light, thereby ensuring the power generation capacity of the flexible solar cell panel 26 and maintaining the energy supply stability of the device.

[0029] like Figure 2 As shown, in this embodiment, the center of the arc rod 13 coincides with the center of the spherical shell 1; the concentric design makes the arc rod 13 more stable during rotation, and at the same time makes the rubber scraper 17 stably fit with the transparent protective shell 27 when the arc rod 13 rotates.

[0030] like Figure 1 and Figure 7 As shown, in the present embodiment, filter screens 16 are inlaid on opposite sides of the suction head 15, and two bent rods 21 are installed at the outer wall of the spherical shell 1 corresponding to the cavity 1-2, and the ends of the bent rods 21 are fixed with fixed blocks 22, and the sides of the fixed blocks 22 are installed with rubber scraper pads 23; the filter screens 16 on both sides of the suction head 15 can effectively filter out large particles of impurities in the water when sucking water samples, prevent these impurities from entering the interior of the device, blocking the water inlet channel 14, and damaging key components such as the water pump 11, thereby ensuring the normal operation of the detection mechanism 9; when the arc rod 13 rotates upward, the suction head 15 rotates upward accordingly, and its side filter screen 16 contacts the rubber scraper pad 23 at the fixed block 22, and the rubber scraper pad 23 is used to scrape off impurities attached to the surface of the filter screen 16, thereby realizing automatic cleaning of the filter screen 16, and further ensuring the suction efficiency and stability of the suction head 15.

[0031] like Figure 7As shown, in this embodiment, a slope 24 is provided on the side of the rubber scraper 23; the design of the slope 24 makes the contact edge of the rubber scraper 23 and the filter 16 sharper, and when cleaning the filter 16, it can more comprehensively and stably scrape off impurities on the surface of the filter 16, thereby ensuring the cleaning effect of the filter 16.

[0032] like Figure 2 As shown, in the present embodiment, a hollow circular shaft 32 is installed on the outer wall of the spherical shell 1, the hollow circular shaft 32 is connected with the drainage channel 33, and the arc 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 rod 13, ensuring that the arc rod 13 can rotate flexibly and smoothly during the process of sucking water samples and cooperating with the action of the flipping mechanism 5. At the same time, the hollow design is connected with the drainage channel 33, which does not affect the normal drainage work of the drainage pump 18, making the structure of the device more compact and reasonable, and improving the space utilization rate.

[0033] like Figure 2 As shown, in this embodiment, hoses 19 are installed on opposite sides of the partition 4 and corresponding to the positions of the drainage holes. The two hoses 19 are respectively located inside cavity 1 2 and cavity 2 3. A counterweight head 20 is fixed at one end of the hose 19 away from the partition 4, and a small hole is opened on the outer wall of the counterweight head 20. When the spherical shell 1 is tilted or rotated due to the influence of water flow, the counterweight head 20 can automatically adjust its position in cavity 1 2 or cavity 2 3 under the action of its own weight, thereby ensuring that the drainage pump 18 can stably pump water in cavity 1 2 and cavity 2 3.

[0034] like Figure 2 As shown, in this embodiment, the hose 19 is a silicone tube and the counterweight head 20 is made of stainless steel; the silicone hose 19 is elastic and prevents clogging when bending through the elasticity of its own tube wall, thereby ensuring that the drainage pump 18 can stably pump water from chamber 1 2 and chamber 2 3, and the stainless steel counterweight head 20 is high in strength and corrosion-resistant, and can increase its service life.

[0035] like Figure 1 As shown, in this embodiment, an indicator light 30 is installed on the outer wall of the spherical shell 1, and the indicator light 30 is electrically connected to the battery pack 28; the indicator light 30 serves as a visual component of the device, and can flash continuously when powered by the battery pack 28, so that the staff can observe the position of the spherical shell 1 when salvaging the spherical shell 1, thereby facilitating the salvage of the spherical shell 1.

[0036] 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 positions in the river. During detection, the water pump 11 is started, and the water pump 11 sucks water from the suction head 15 and sequentially passes through the water inlet channel 14 and the hollow shaft 7, and then discharges it from the water supply hole 12 to the cavity 2 3. The water quality detection sensor 10 in the cavity 2 3 detects the inflowing water sample. At the same time, as the amount of water in the cavity 2 3 increases, the spherical shell 1 sinks under the combined effect of the weight of the water in the cavity 2 3 and the weight of the battery pack 28; After the ball shell 1 sinks and the water sample in the cavity 2 3 is detected, the servo motor 6 drives the inner ball 8 to rotate, so that the water supply hole 12 on the inner ball 8 is transferred to the cavity 1 2, and the water pump 11 is operated again to inject water into the cavity 1 2, and the water quality detection sensor 10 is detected again, thereby realizing a comprehensive detection of the water quality at different depths of the river. After the detection is completed, the drainage pump 18 works, and the water in the cavity 1 2 and the cavity 2 3 enters from 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 at the drainage channel 33. After the water in the cavity 1 2 and the cavity 2 3 is discharged, the ball shell 1 floats back to the water surface due to the weight reduction, and can float with the water flow, thereby widening the detection range and making the detection more flexible; A flexible solar panel 26 is adhered in the groove 25 of the upper part of the spherical shell 1. When exposed to sunlight, the solar energy can be converted 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, the arc rod 13 is driven to rotate upward through the hollow shaft 7, and the rubber scraper 17 rotates accordingly. When the rubber scraper 17 contacts the transparent protective shell 27, the rubber scraper 17 is used to scrape off impurities attached to the surface of the transparent protective shell 27 to prevent the impurities from adhering to and blocking the light, thereby ensuring the power generation capacity of the flexible solar panel 26. When the arc rod 13 rotates upward, the suction head 15 is driven 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 fixed block 22 at the end of the curved rod 21. The side slope 24 of the rubber scraper pad 23 is designed to scrape away impurities, realize automatic cleaning of the filter screen 16, and ensure that the suction head 15 can stably extract water samples. After the water in chamber 1 2 and chamber 2 3 is drained, the servo motor 6 drives the inner sphere 8 to rotate in the opposite direction, thereby rotating the arc rod 13 to the bottom of chamber 2 3, and at the same time rotating the water quality detection sensor 10 to chamber 2 3, waiting for another detection and use.

[0037] The present invention encompasses any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
