Description

Technical Field

[0001] The invention belongs to the technical field of water pollution control, and in particular relates to a device for absorbing harmful substances in water. Background Art

[0002] With the rapid advancement of my country's industrialization, urbanization and new countryside construction, a large amount of industrial waste, construction waste and domestic waste are dumped indiscriminately, waste liquid, wastewater and sewage are discharged at will, and a large amount of dead branches and leaves, residual animal manure, etc. generated by rural planting and breeding industries are dumped into nearby rivers, causing serious pollution. The water body turns black and smells, resulting in the disappearance of fish and shrimp in the river, and the river water is useless. Especially in the rivers near urban and rural fringe areas and industrial blocks, the pollution is particularly serious and the ecological environment is severely damaged.

[0003] At present, the treatment of rivers and lakes polluted by harmful substances usually involves first adding adsorbents to the polluted water, waiting for the harmful substances to be adsorbed and settle to the bottom of the river, then pumping out the sewage, cleaning the sludge, and finally draining the water back. This method is certainly good, but a large amount of adsorbents is required in the early stage, and the large-scale use of chemical adsorbents has potential impacts on the environment.

[0032] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a device for absorbing harmful substances in water, such as Figure 1-11 As shown, the harmful substance adsorption device in the water body includes: an annular floating airbag 1, which is a regular annular structure; a support ring 2, which is fixedly installed on the inner ring of the annular floating airbag 1; a hanging suspension shell 3, which is fixedly installed on the inner ring of the support ring 2, and the hanging suspension shell 3 is provided with a power groove 4 in the middle of the top and a through-port 5 in the middle of the bottom; a hanging connection tube 6, which is placed in the power groove 4, and the bottom extends to the through-port 5; an adsorption medium placement net tube 7, which is fixedly installed at the bottom of the hanging connection tube 6 and is used to place the adsorption medium.

[0035] In this embodiment, when the device is in use, the annular floating airbag 1 is first used to stably suspend it in the water body. The support ring 2 serves as a structural support to ensure the overall stability of the device. The power slot 4 in the hanging suspension shell 3 provides an installation space for the hanging connection tube 6, and the through-hole 5 allows the hanging connection tube 6 and the adsorption medium placement net tube 7 at the bottom thereof to be freely suspended in the water body. The adsorption medium (such as activated carbon, biochar, etc.) is placed in the adsorption medium placement net tube 7. When the device is placed in a polluted water body, the adsorption medium begins to adsorb and remove harmful substances in the water.

[0036] The working principle of the device is mainly based on adsorption. The adsorption medium in the adsorption medium placement net tube 7 has a large specific surface area and pore structure, and can effectively adsorb harmful substances in water, such as heavy metal ions, organic matter, pigments, etc. When water flows through the adsorption medium placement net tube 7, the harmful substances are adsorbed on the surface of the adsorption medium, thereby achieving the purpose of purifying water quality.

[0037] The device is suitable for the treatment of various polluted water bodies, including industrial wastewater, domestic sewage, agricultural wastewater, etc. In particular, for those water bodies with high concentrations of harmful substances that are difficult to treat by traditional methods, the device shows good application prospects. In addition, since the device adopts a suspended design and is not restricted by terrain and water depth, it can be widely used in pollution control of natural waters such as rivers, lakes, and reservoirs.

[0038] The device adopts a suspended design and does not require complicated installation and fixing steps. It can start working by simply placing the device in the polluted water body. The device is suitable for the treatment of various polluted water bodies and is not restricted by terrain and water depth. It has broad application prospects. It does not require a large amount of energy and chemicals during operation, and is environmentally friendly and energy-saving. The device has a simple structure and is easy to clean and maintain, reducing operating costs.

[0039] In a further preferred embodiment of the present invention, the height of the support ring 2 is less than the height of the annular floating airbag 1, the upper and lower sides of the support ring 2 do not exceed the upper and lower sides of the annular floating airbag 1, the height of the hanging floating shell 3 is greater than the height of the annular floating airbag 1, and the upper and lower sides of the hanging floating shell 3 extend to the outside of the annular floating airbag 1.

[0040] In this embodiment, the height of the support ring 2 is designed to be smaller than the height of the annular floating airbag 1, which means that the upper and lower sides of the support ring 2 will not exceed the boundaries of the annular floating airbag 1. Such a design helps to maintain the stability and balance of the device, ensuring that the device will not tilt or roll due to the shift of the center of gravity during the suspension process.

[0041] At the same time, the height of the hanging floating shell 3 is set to be greater than the height of the annular floating airbag 1, and its upper and lower sides extend to the outside of the annular floating airbag 1. This design has several advantages: first, it increases the buoyancy of the device, so that the entire device can be stably suspended in a wider range of waters; second, it expands the exposure area of ​​the adsorption medium placing net tube 7 in the water, thereby improving the efficiency of adsorbing harmful substances; finally, this design also enhances the stability and adaptability of the device under complex water flow conditions.

[0042] In a further preferred embodiment of the present invention, the power slot 4 and the through-hole 5 are connected and pass through the hoisting suspension shell 3 , and the power slot 4 and the through-hole 5 are both opened in a circular shape, and the inner diameter of the through-hole 5 is smaller than the inner diameter of the power slot 4 .

[0043] In this embodiment, the design of the power tank 4 and the through-port 5 in this solution ensures the stability and efficient operation of the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7.

[0044] Specifically, the power tank 4 and the through-port 5 are connected and pass through the entire hoisting suspension shell 3. Such a design enables the suspension connecting tube 6 to be stably placed in the power tank 4, and its bottom can smoothly pass through the through-port 5, thereby ensuring that the adsorption medium placement net tube 7 can be completely immersed in the water body.

[0045] The power tank 4 and the through-port 5 are both designed to be circular, which makes the structure more stable and can withstand greater water flow impact. In addition, the inner diameter of the through-port 5 is smaller than the inner diameter of the power tank 4. This design helps to fix the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7 to prevent them from shaking or deflecting under the action of water flow, thereby ensuring the stability and working efficiency of the adsorption medium placement net cylinder 7.

[0046] Since the stability and working efficiency of the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7 are improved, the device is less likely to fail or be damaged during long-term operation, thereby reducing the cost of maintenance and replacement.

[0047] In a further preferred embodiment of the present invention, the suspension connecting tube 6 has an upper section with a bead and a lower section with a straight tube, the outer ring of the bead and the lower side of the suspension connecting tube 6 are rotatably contacted with the inner wall of the power groove 4, the straight tube of the suspension connecting tube 6 is located in the through-opening 5, and the diameter of the straight tube of the suspension connecting tube 6 is smaller than the inner diameter of the through-opening 5.

[0048] In this embodiment, the suspension connecting tube 6 adopts a unique structure of an upper edge and a lower straight tube.

[0049] The outer ring and the lower side of the suspension connection tube 6 are rotatably contacted with the inner wall of the power groove 4. This design allows the suspension connection tube 6 to rotate freely in the power groove 4, and this rotatable connection mode also helps the suspension connection tube 6 to flexibly adjust the angle when needed.

[0050] The straight portion of the suspension connection tube 6 is located in the through-opening 5, and its diameter is smaller than the inner diameter of the through-opening 5. This design ensures that the straight portion of the suspension connection tube 6 can pass through the through-opening 5 smoothly.

[0051] In a further preferred embodiment of the present invention, a protective mesh cover 8 is fixedly installed on the bottom of the hoisting suspension shell 3, and the protective mesh cover 8 is located outside the upper end of the adsorption medium placement net tube 7, and the protective mesh cover 8 has a through hole for the adsorption medium placement net tube 7 to move through.

[0052] In this embodiment, the protective mesh cover 8 is fixedly installed at the bottom of the hoisting suspension shell 3, and its position is located outside the upper end of the adsorption medium placement net tube 7. The presence of the protective mesh cover 8 can also effectively prevent large impurities or floating objects in the water body from entering the adsorption medium placement net tube 7, thereby protecting the adsorption medium from pollution and improving its service life and adsorption efficiency.

[0053] The protective net cover 8 is designed with a through hole for the adsorption medium placement net cylinder 7 to move through. This design allows the adsorption medium placement net cylinder 7 to rotate freely in the water body, thereby ensuring that the adsorption medium can fully contact the water body and improve the adsorption efficiency. At the same time, the design of the through hole also takes into account sufficient space to avoid excessive restrictions on the movement of the adsorption medium placement net cylinder 7.

[0054] In a further preferred embodiment of the present invention, the hoisting suspension shell 3 is provided with power chambers 9 located on both sides of the power slot 4, and the hoisting suspension shell 3 and the protective net cover 8 are provided with a pair of power mechanisms, and the pair of power mechanisms are respectively arranged corresponding to the two power chambers 9.

[0055] In this embodiment, the suspension shell 3 is provided with power chambers 9 on both sides of the power tank 4. The two power chambers 9 provide installation space for the power mechanism, so that the device can adjust the angle of the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7 as needed.

[0056] At the same time, a pair of power mechanisms are provided on the suspension shell 3 and the protective net cover 8, and the pair of power mechanisms are respectively arranged corresponding to the two power chambers 9. The power mechanism enables the whole to move in the water, and the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7 can flexibly rotate in the water.

[0057] Through this design, the harmful substance adsorption device in water of the present invention has stronger controllability and adaptability in practical applications. The operator can adjust the adsorption position of the entire device by controlling the power mechanism according to factors such as the flow of the water body, the distribution of harmful substances, and the use of the adsorption medium, thereby improving the adsorption efficiency.

[0058] In a further preferred embodiment of the present invention, the power mechanism includes a drive motor 10, a drive spindle 11, an impeller shaft 12, an impeller blade 13, an active bevel gear 14 and a driven bevel gear 15, the drive motor 10 is fixedly installed in the power chamber 9, the bottom of the hanging suspension shell 3 is rotatably installed with a drive spindle 11, the drive spindle 11 is vertically arranged in the longitudinal direction, the top end of the drive spindle 11 extends into the power chamber 9, and the bottom end extends into the protective net cover 8, the top end of the drive spindle 11 is connected to the drive motor The output shaft of the machine 10 is fixedly connected, and an impeller shaft 12 located below the driving main shaft 11 is rotatably installed in the protective net cover 8. The impeller shaft 12 is longitudinally arranged and perpendicular to the driving main shaft 11. A plurality of impeller blades 13 are fixedly installed on the impeller shaft 12 for paddling to drive the device to move. An active bevel gear 14 is fixedly provided on the bottom end of the driving main shaft 11, and a driven bevel gear 15 is fixedly provided on the impeller shaft 12. The active bevel gear 14 is meshed with the driven bevel gear 15.

[0059] In this embodiment, the device for absorbing harmful substances in water of the present invention introduces a power mechanism design to provide more flexible and efficient controllability. This design enables the device to actively paddle and achieve autonomous movement, thereby covering a wider range of polluted waters and improving treatment efficiency.

[0060] Specifically, the power mechanism includes a drive motor 10, a drive main shaft 11, an impeller shaft 12, an impeller blade 13, an active bevel gear 14 and a driven bevel gear 15. The drive motor 10 is fixedly installed in the power chamber 9 to provide a power source for the entire power mechanism. The drive main shaft 11 is rotatably installed at the bottom of the hanging suspension shell 3. The drive main shaft 11 is vertically arranged in the longitudinal direction, and its top end extends into the power chamber 9 and is fixedly connected to the output shaft of the drive motor 10, and the bottom end extends into the protective mesh cover 8.

[0061] Inside the protective net cover 8, at a position below the driving main shaft 11, an impeller shaft 12 is rotatably mounted. The impeller shaft 12 is arranged longitudinally, perpendicular to the driving main shaft 11, and a plurality of impeller blades 13 are fixedly mounted thereon. These impeller blades 13 rotate under the drive of the driving main shaft 11, paddle the water body, and provide the device with forward power.

[0062] In order to realize the power transmission between the driving main shaft 11 and the impeller shaft 12, the bottom end of the driving main shaft 11 is fixedly sleeved with an active bevel gear 14, and the impeller shaft 12 is fixedly sleeved with a driven bevel gear 15. The active bevel gear 14 is meshed with the driven bevel gear 15 to ensure that the power is smoothly transmitted from the driving main shaft 11 to the impeller shaft 12, thereby driving the impeller blade 13 to rotate.

[0063] This design enables the device to move actively as needed, covering a wider area of ​​water and improving the treatment efficiency. At the same time, due to the rotation of the impeller blades 13, the device can also generate a certain amount of water flow disturbance during movement, which helps to improve the contact efficiency between the adsorption medium and the harmful substances in the water body, and further enhance the treatment effect.

[0064] In summary, by introducing the design of the power mechanism, the harmful substance adsorption device in water of the present invention has been significantly improved in terms of controllability, adaptability and treatment efficiency, providing a more efficient, flexible and practical solution for water pollution control.

[0065] In a further preferred embodiment of the present invention, a plurality of teeth 16 are fixedly mounted on the outer ring of the suspension connection cylinder 6, and the plurality of teeth 16 are evenly arranged in a circular array and are located in the through-port 5. A rotating drive shaft 17 is rotatably mounted on the inner wall of one side adjacent to the through-port 5 and any one of the power chambers 9, and both ends of the rotating drive shaft 17 are respectively located in the through-port 5 and the corresponding power chamber 9. A driving circular gear 18 is fixedly sleeved on one end of the rotating drive shaft 17 located in the through-port 5, and the driving circular gear 18 is meshed with the teeth 16, and is used to drive the suspension connection cylinder 6 and the adsorption medium placing net cylinder 7 to rotate. An active bevel gear 2 19 is fixedly sleeved on the driving main shaft 11 corresponding to the rotating drive shaft 17, and a driven bevel gear 2 20 is fixedly sleeved on one end of the rotating drive shaft 17 located in the power chamber 9, and the driven bevel gear 2 20 is meshed with the active bevel gear 2 19.

[0066] In this embodiment, the device for adsorbing harmful substances in water of the present invention has an innovative design in the rotation mechanism of the suspension connecting cylinder 6. This design enables the suspension connecting cylinder 6 and the adsorption medium placement net cylinder 7 to rotate more flexibly, thereby increasing the contact area with the harmful substances in the water and improving the adsorption efficiency.

[0067] Specifically, a plurality of teeth 16 are fixedly mounted on the outer ring of the suspension connection tube 6, and the teeth 16 are evenly arranged in a circular array and located in the through-hole 5. Such a design enables the teeth 16 to effectively mesh with the drive mechanism when the suspension connection tube 6 rotates in the through-hole 5, thereby achieving stable and efficient rotation.

[0068] In order to realize the rotation of the suspension connection cylinder 6, the present invention rotatably installs a rotation drive shaft 17 on the inner wall of one side adjacent to the through-hole 5 and any power chamber 9. The two ends of the rotation drive shaft 17 are respectively located in the through-hole 5 and the corresponding power chamber 9, so that the rotation drive shaft 17 can be connected to the suspension connection cylinder 6 and the power mechanism at the same time.

[0069] At one end of the through hole 5, the rotating drive shaft 17 is fixedly sleeved with a driving circular gear 18, which meshes with the teeth 16 on the suspension connection tube 6. When the rotating drive shaft 17 rotates, the driving circular gear 18 drives the suspension connection tube 6 to rotate together through the teeth 16. Such a design ensures that the rotation of the suspension connection tube 6 is stable and controllable.

[0070] In order to drive the rotation of the rotating drive shaft 17, the present invention is provided with a fixed sleeve of an active bevel gear 2 19 on the driving main shaft 11 corresponding to the rotating drive shaft 17, and a fixed sleeve of a driven bevel gear 2 20 is provided at one end of the rotating drive shaft 17 located in the power chamber 9. The active bevel gear 2 19 is meshed with the driven bevel gear 2 20 to form a gear transmission mechanism. When the driving motor 10 drives the driving main shaft 11 to rotate, the active bevel gear 2 19 will drive the driven bevel gear 2 20 to rotate together, thereby driving the rotating drive shaft 17 and the driving circular gear 18 to rotate, and finally driving the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7 to rotate.

[0071] This design allows the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7 to be flexibly rotated as needed. By adjusting the rotation speed and direction of the suspension connection cylinder 6, the contact mode and contact time between the adsorption medium and the harmful substances in the water body can be optimized, thereby further improving the adsorption efficiency. At the same time, this design also increases the flexibility and adaptability of the device, enabling it to better adapt to different water environments and treatment needs.

[0072] In a further preferred embodiment of the present invention, the rotating drive shaft 17 is arranged in parallel with the corresponding impeller shaft 12 , the diameter of the adsorption medium placement net cylinder 7 is smaller than the diameter of the suspension connection cylinder 6 , and is staggered with the driving circular gear 18 .

[0073] In this embodiment, the harmful substance adsorption device in water of the present invention has been carefully adjusted in the layout of the rotating drive shaft 17 and the impeller shaft 12, as well as the size and position of the net cylinder 7 for placing the adsorption medium, so as to improve the overall operating efficiency and safety.

[0074] First, the rotary drive shaft 17 is arranged in parallel with the corresponding impeller shaft 12. This parallel layout not only makes the overall structure more compact and reduces unnecessary space occupation, but also reduces the risk of mechanical failure caused by mutual interference. More importantly, this design enables the rotary drive shaft 17 and the impeller shaft 12 to work together to drive the movement of the suspension connection cylinder 6 and the adsorption medium placement net cylinder 7, thereby improving the overall work efficiency.

[0075] Secondly, the diameter of the adsorption medium placement net cylinder 7 is smaller than the diameter of the suspension connection cylinder 6, and is staggered with the drive circular gear 18. This design has two advantages: on the one hand, the smaller diameter enables the adsorption medium placement net cylinder 7 to rotate more flexibly in the water body, thereby contacting and adsorbing harmful substances more widely; on the other hand, it is also convenient to take out the adsorption medium placement net cylinder 7 to replace the internal adsorption medium.

[0076] In a further preferred embodiment of the present invention, a closing cover 21 is detachably installed on the top of the hoisting suspension shell 3 for closing the power tank 4, a solar panel 22 is fixedly installed on the top of the closing cover 21, and a controller 23 is fixedly installed on the bottom of the closing cover 21, which can be located in the power tank 4 and is used to control the drive motor 10.

[0077] In this embodiment, the harmful substance adsorption device in water of the present invention is designed with a detachable closing cover 21 on the top of the suspended floating shell 3, and a solar panel 22 and a controller 23 are integrated on the closing cover 21.

This makes the harmful substance adsorption device in water of the present invention more advantageous in practical applications and can better meet the needs of water pollution control.

[0082] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0083] In another embodiment of the present invention, a mounting cover 24 is detachably mounted on the top of the suspension connection cylinder 6, a stirring shaft 25 is penetrated and mounted on the mounting cover 24, the mounting cover 24 can rotate and slide up and down along the stirring shaft 25, a portion of the stirring shaft 25 located below the mounting cover 24 is fixedly mounted with a plurality of stirring rods 45, the plurality of stirring rods 45 can be located in the adsorption medium placement net cylinder 7, and can be used to stir the adsorption medium, a connector 26 is fixedly mounted on the top of the stirring shaft 25, a rectangular slide 27 is fixedly mounted on the top of the connector 26, a rectangular sleeve 28 can be slidably sleeved on the rectangular slide 27, and the The top of the rectangular sleeve 28 is fixedly connected to the bottom of the closing cover 21, and a return spring 29 fixedly connected to the connecting head 26 is provided inside the rectangular slide 27. The top of the return spring 29 contacts the bottom of the closing cover 21. The connecting head 26 is provided with a walking ring 30 fixedly connected to the top of the assembly cover 24. The top of the walking ring 30 forms a walking guide inclined surface 31. A support shaft 32 is fixedly installed on one side of the connecting head 26. One end of the support shaft 32 extends to the top of the walking guide inclined surface 31 and is rotatably sleeved with a walking wheel 33. The walking wheel 33 can roll along the walking guide inclined surface 31.

[0084] In this embodiment, a detachable assembly cover 24 is designed on the top of the suspension connection cylinder 6, and a stirring shaft 25 and related components are provided to stir the adsorption medium during the adsorption process to improve the adsorption efficiency. The following is a detailed description of this embodiment:

[0085] The assembly cover 24 is penetrated with a stirring shaft 25, so that the stirring shaft 25 can rotate and slide up and down therein, and the stirring shaft 25 located below the assembly cover 24 is fixedly mounted with a plurality of stirring rods 45, and these stirring rods 45 can all be extended into the adsorption medium placement net cylinder 7. When the stirring shaft 25 rotates, the stirring rods 45 will rotate accordingly, thereby stirring the adsorption medium, increasing its contact area and contact time with harmful substances in the water body, and improving the adsorption efficiency.

[0086] In order to control the lifting and rotation of the stirring shaft 25, the present invention fixes a connector 26 on the top of the stirring shaft 25. A rectangular slide 27 is fixed on the connector 26, and a slidable rectangular sleeve 28 is sleeved in the rectangular slide 27. The top of the rectangular sleeve 28 is fixedly connected to the bottom of the closed cover 21. In use, since the adsorption medium placement net cylinder 7 rotates, the adsorption medium placement net cylinder 7 drives the assembly cover 24 and the walking ring 30 to rotate synchronously;

[0087] At this time, in order to guide the lifting and lowering movement of the stirring shaft 25 and ensure its stability, the present invention sets a walking ring 30 outside the connecting head 26. The top of the walking ring 30 forms a walking guide inclined surface 31, and a support shaft 32 is fixed to one side of the connecting head 26. One end of the support shaft 32 extends to the top of the walking guide inclined surface 31 and is sleeved with a rotatable walking wheel 33.

[0088] When the walking ring 30 rotates, the rectangular sleeve 28 and the rectangular slide 27 limit the connecting head 26 and the stirring shaft 25 so that they will not rotate. At this time, the rotating walking ring 30 uses the walking guide slope 31 to cooperate with the walking wheel 33 to lift the connecting head 26, thereby lifting the stirring shaft 25. At this time, the rectangular slide 27 slides along the rectangular sleeve 28 and compresses the reset spring 29. The reset spring 29 is compressed or released to cooperate in reciprocating motion. When the stirring shaft 25 is lifted or lowered, the walking wheel 33 rolls along the walking guide slope 31 to ensure the smooth lifting and lowering of the stirring shaft 25. The lifted stirring shaft 25 drives the stirring rod 45 to lift and lower synchronously, thereby improving the stirring effect of the adsorption medium. It should be noted that the adsorption medium must not enter the suspension connecting tube 6 when being put in to provide a movement gap during stirring.

[0089] In the present invention, the top end of the return spring 29 is in contact with the closing cover 21 , and the rectangular sleeve 28 and the rectangular slide 27 are slidably connected and can be actually pulled apart without affecting the disassembly of the closing cover 21 .

[0090] In summary, the stirring shaft 25 and related component designs in this embodiment can effectively stir the adsorption medium, improve its contact efficiency with harmful substances in the water body and improve the adsorption effect. At the same time, the coordination of the walking wheel 33 and the walking guide inclined surface 31 ensures the stability and reliability of the lifting movement of the stirring shaft 25.

[0091] In another embodiment of the present invention, two mounting openings 34 are provided on the corresponding two sides of the support ring 2, and a chemical storage cylinder 35 can be detachably installed in the two mounting openings 34. The side of the chemical storage cylinder 35 is detachably connected to the support ring 2 by a fixing block 36. The bottom of the chemical storage cylinder 35 has a discharge opening 37, and the height of the discharge opening 37 is higher than the water surface by more than 20CM. The discharge opening 37 is located on one side of the hoisting suspension shell 3 and is rotatably installed with a driven shaft 38. The driven shaft 38 is A plurality of discharge blades 40 are fixedly installed on the part of the driving shaft 38 located in the discharge port 37, and a driving shaft 39 is rotatably installed on the side of the power chamber 9 adjacent to the mounting port 34. The end of the driving shaft 39 located in the mounting port 34 is detachably connected to the driven shaft 38, and a driven bevel gear three 41 is fixedly installed on the end of the driving shaft 39 located in the power chamber 9. An active bevel gear three 42 is fixedly sleeved on the driving spindle 11, and the active bevel gear three 42 is meshed with the driven bevel gear three 41.

[0092] In this embodiment, two installation openings 34 are provided on both sides of the support ring 2, and the two installation openings 34 are used to install a chemical storage cylinder 35. The chemical storage cylinder 35 is used to store chemicals that need to be put into the water body, such as disinfectants, flocculants, etc. The side of the chemical storage cylinder 35 is detachably connected to the support ring 2 through a fixing block 36, and such a design facilitates replacement or cleaning of the chemical storage cylinder 35 when necessary.

[0093] A discharge port 37 is provided at the bottom of the chemical storage tube 35. The height of the discharge port 37 is set to be more than 20 cm above the water surface to prevent the release of the chemical from being affected by water fluctuations. A driven shaft 38 is rotatably installed on the side of the discharge port 37 where the suspended shell 3 is suspended. A plurality of discharge blades 40 are fixedly installed on the part of the driven shaft 38 inside the discharge port 37. When the driven shaft 38 rotates, these discharge blades 40 can push the chemical to be discharged from the discharge port 37.

[0094] In order to drive the driven shaft 38 to rotate, the present invention rotatably installs a driving shaft 39 on one side of the power chamber 9 adjacent to the mounting opening 34. One end of the driving shaft 39 located in the mounting opening 34 is detachably connected to the driven shaft 38, so that the rotation of the driving shaft 39 can drive the driven shaft 38 to rotate, thereby driving the discharge blade 40 to work.

[0095] A driven bevel gear 3 41 is fixedly mounted on one end of the driving shaft 39 located in the power chamber 9, and a driving bevel gear 3 42 is fixedly sleeved on the driving main shaft 11. The driving bevel gear 3 42 meshes with the driven bevel gear 3 41, so that when the driving main shaft 11 rotates, the driving shaft 39 can be rotated through the transmission of the driving bevel gear 3 42 and the driven bevel gear 3 41, thereby driving the discharge blade 40 to work.

[0096] Usage and principle: When it is necessary to put chemical agents into the water body, it is only necessary to start the driving main shaft 11 to rotate it. The rotation of the driving main shaft 11 will drive the driving bevel gear three 42 to rotate, and then the driven bevel gear three 41 and the driving shaft 39 to rotate. The rotation of the driving shaft 39 will drive the driven shaft 38 and the discharge blade 40 to rotate, so that the chemical agents are discharged from the discharge port 37.

[0097] This design is suitable for situations where chemical agents need to be added to the water body, such as sewage treatment, water purification, etc. When treating the water body, a small amount of chemical agents is used to minimize the impact on the environment. After the sewage is adsorbed, it is extracted and finally the silt on the riverbed is cleaned.

[0098] By this design, chemical agents can be conveniently placed in the water body, and the placing speed and the placing amount of the agents can be adjusted as required. In addition, due to the height setting of the discharge port 37, the accidental release of the agents can be prevented to a certain extent, thereby improving the safety of use.

[0099] In another embodiment of the present invention, a rectangular connecting groove 43 is formed at one end of the driving shaft 39 connected to the driven shaft 38 , and a rectangular connecting block 44 is fixedly installed at one end of the driven shaft 38 , and the rectangular connecting block 44 can be embedded in the rectangular connecting groove 43 .

[0100] In this embodiment, the connection method between the driving shaft 39 and the driven shaft 38 is further optimized, and specifically a detachable connection method of a rectangular connection groove 43 and a rectangular connection block 44 is adopted.

[0101] Specifically, the driving shaft 39 has a rectangular connecting groove 43 at one end connected with the driven shaft 38. The shape and size of this rectangular connecting groove 43 are precisely designed to ensure matching with the rectangular connecting block 44 on the driven shaft 38.

[0102] At the same time, a rectangular connecting block 44 is fixedly installed at one end of the driven shaft 38. The size and shape of this rectangular connecting block 44 are completely consistent with the rectangular connecting groove 43, and can be accurately embedded in the rectangular connecting groove 43.

[0103] When removing or installing the chemical storage cylinder 35, when the driving shaft 39 and the driven shaft 38 need to be connected, it is only necessary to align the rectangular connecting block 44 with the rectangular connecting groove 43 and then insert it. This connection method is not only simple and fast, but also firmly connected, which can ensure that when the driven shaft 38 rotates, the driving shaft 39 can rotate synchronously, thereby driving the discharge blade 40 to work.

[0104] Due to the detachable connection mode, when the chemical storage cylinder 35 needs to be removed, it is only necessary to take out the rectangular connection block 44 from the rectangular connection groove 43 without removing other components, which greatly improves the convenience of maintenance.

[0105] The method and principle of use are the same as those of the previous embodiment. When the driving main shaft 11 rotates, the driving shaft 39 is rotated through the transmission of the active bevel gear three 41 and the driven bevel gear three 42, and then the driven shaft 38 and the discharge blade 40 are driven to rotate through the connection between the rectangular connecting block 44 and the rectangular connecting groove 43, thereby realizing the delivery of chemical agents.

[0106] This detachable connection mode of the rectangular connection groove 43 and the rectangular connection block 44 not only improves the firmness of the connection and the convenience of maintenance, but also further enhances the practicality and reliability of the present invention.

[0107] In summary, compared with related technologies, this device adopts a suspended design and does not require complicated installation and fixing steps. It only needs to be placed in the polluted water body to start working. This device is suitable for the treatment of various polluted water bodies, is not restricted by terrain and water depth, and has broad application prospects. It does not require a large amount of energy and chemicals during operation, and is environmentally friendly and energy-saving. The device has a simple structure and is easy to clean and maintain, which reduces operating costs.
