Description

Technical Field

[0001] The invention belongs to the technical field of water reservoirs, and in particular relates to an environmentally friendly water reservoir for water conservancy projects. Background Art

[0002] The environmental protection water storage tank device for small water conservancy projects is a relatively compact water storage facility designed for small water conservancy projects, with a focus on environmental protection functions. It is usually a device that collects, stores and utilizes water resources in a small area and minimizes the negative impact on the surrounding environment.

[0003] During the operation of the reservoir, the precipitation of water is inevitable. Due to the relatively simple design of traditional small reservoirs, it is difficult to effectively clean up the silt and other sediments that gradually accumulate at the bottom of the pool during the water storage period. As time goes by, the silt continues to accumulate and will occupy a considerable part of the pool space, which will directly lead to a significant reduction in the amount of water stored, weakening the original water storage capacity of the reservoir and failing to fully meet the water demand. Not only that, the silt at the bottom of the pool will ferment after a long period of accumulation. This process will breed a large number of harmful microorganisms and various chemical substances, such as ammonia nitrogen, hydrogen sulfide, etc., which will seriously damage the water quality of the reservoir, making the water turbid and emitting odors, and may even cause a decrease in the dissolved oxygen content in the water, threatening the survival of aquatic organisms. This deterioration of water quality is extremely unfavorable for the storage and subsequent rational use of water sources. Whether it is used for agricultural irrigation, it may affect the growth of crops, or as miscellaneous water for daily life, it will also bring potential risks to the health of users. Therefore, innovative solutions are urgently needed to improve this situation. Summary of the invention

[0020] To further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.

[0021] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Please refer to Figures 1 to 6, an environmental protection reservoir for water conservancy projects provided by an embodiment of the present invention includes a housing 1. The housing 1 includes a water inlet mechanism 2 and a water outlet mechanism 3. It is characterized in that a plurality of first sub-holes 4 are arranged on the bottom wall of the housing 1 in an annular array. A rotatable retaining plate 5 is provided on the bottom wall of the housing 1. A connecting shaft 6 is fixedly connected to the center of the retaining plate 5. The connecting shaft 6 is connected to the bottom wall of the housing 1. A plurality of second sub-holes 7 are arranged on the retaining plate 5 in an annular array. When at least a part of the second sub-holes 7 coincides with the first sub-holes 4, water and impurities are discharged from the coincident part. A bearing frame 8 is provided on the upper side of the housing 1. A motor 9 is provided on the bearing frame 8. The output end of the motor 9 is fixedly connected to a rotating shaft 10 through a coupling. The rotating shaft 10 is rotatably connected to the bearing frame 8 through a bearing. Blades 11 are provided on the rotating shaft 10.

[0023] Through this setting, during the normal operation of the environmental protection reservoir for water conservancy projects, water enters the interior of the housing 1 through the water inlet mechanism 2. As time goes by, impurities in the water (such as sediment, suspended particles, etc.) gradually settle to the bottom wall of the housing 1 under the action of gravity. And when needed, the water in the housing 1 can be pumped out through the water outlet mechanism 3. When it is necessary to clean the precipitated impurities, the motor 9 on the bearing frame 8 is started. The output end of the motor 9 drives the rotating shaft 10 to rotate, and the blades 11 on the rotating shaft 10 rotate at a high speed accordingly. During the rotation of the blades 11, the precipitated impurities at the bottom of the housing 1 are disturbed, so that the impurities are fully mixed with the surrounding water to form a mixed liquid with a higher impurity content. Since a plurality of first sub-holes 4 are arranged on the bottom wall of the housing 1 in an annular array, and a rotatable retaining plate 5 is provided at the bottom wall of the housing 1, and there are a plurality of second sub-holes 7 arranged on the retaining plate 5 in an annular array. When the motor 9 drives the rotating shaft 10 to rotate, the retaining plate 5 is rotated. When at least a part of the second sub-holes 7 coincides with the first sub-holes 4, under the push of the water pressure in the housing 1 and the power generated by the stirring of the blades 11, the water mixed with impurities is discharged from the holes in the coincident part out of the housing 1, realizing the cleaning work of the impurities. The discharged impurities can be transported to a special treatment area through subsequent drainage pipes or channels to prevent pollution to the surrounding environment.

[0024] Traditional reservoirs often have difficulty in efficiently cleaning impurities such as silt deposited at the bottom of the pool, resulting in the accumulation of impurities, reducing the water storage capacity and affecting the water quality. However, through the cooperation of the first sub-holes 4, the motor 9, the rotating shaft 10 and the blades 11, this environmental protection reservoir can actively mix the impurities deposited at the bottom with water and discharge them, effectively solving the problem of impurity accumulation, ensuring the effective water storage capacity of the reservoir, and maintaining its normal water storage function.

[0025] Moreover, the first sub-holes 4 and the second sub-holes 7 are distributed in an annular array, and the motor 9 is used to drive the baffle plate 5 to rotate to control the impurity discharge timing and the impurity discharge amount. The structural design is relatively compact and reasonable. The operator only needs to start the motor 9 to achieve the impurity cleaning work, without complex manual dredging operations, reducing the labor intensity and maintenance costs. Timely cleaning of the impurities at the bottom of the pool also helps to prevent the fermentation of impurities from having an adverse impact on the stored water quality, ensuring the storage quality of the water source, enabling the reservoir to provide cleaner and higher-quality water for related water conservancy projects such as irrigation and industrial water use, reducing the potential harm caused by water pollution to the surrounding ecological environment and water users, meeting the environmental protection requirements, and being conducive to the sustainable development of water conservancy projects.

[0026] Furthermore, a first gear 12 is fixedly connected to the connecting shaft 6; a second gear 13 is fixedly connected to the rotating shaft 10, and the second gear 13 meshes with the first gear 12.

[0027] With this setting, when the motor 9 is started, the output end of the motor 9 drives the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 will drive the connecting shaft 6 to rotate through gear transmission, and then the baffle plate 5 will rotate. In this process, because the tooth number ratio of the second gear 13 to the first gear 12 is set such that the second rotating shaft 10 rotates several circles to drive the first rotating shaft 10 to rotate one circle, when the rotating shaft 10 drives the blades 11 to stir the impurities at a high speed, the baffle plate 5 rotates at a relatively slow speed. When the rotating shaft 10 drives the blades 11 to rotate at a high speed, the blades 11 violently disturb the impurities deposited at the bottom of the housing 1, causing the impurities to be fully mixed with the water to form a mixed liquid. During the slow rotation of the baffle plate 5, for a part of the time, the second sub-holes 7 do not coincide with the first sub-holes 4. At this time, the mixed liquid in the housing 1 is fully circulated and mixed inside under the stirring of the blades 11 and will not be discharged outward. As the baffle plate 5 rotates, when the second sub-holes 7 gradually coincide with the first sub-holes 4, under the push of the water pressure in the housing 1 and the remaining power generated by the stirring of the blades 11, the water mixed with impurities will be discharged from the overlapping part of the holes out of the housing 1, realizing the impurity cleaning work.

[0028] The rotation of the rotating shaft 10 is converted into two functions, namely, the stirring of the blade 11 and the rotation of the baffle plate 5 through gear transmission, realizing the efficient integrated utilization of power. Driven by the same power source (motor 9), the blade 11 can fully stir and mix impurities, and the rotation of the baffle plate 5 can be accurately controlled to achieve the timed and quantitative discharge of impurities, avoiding problems such as increased cost and complex structure caused by setting multiple power devices, and improving the operation efficiency and stability of the entire device. And since the second sub-hole 7 of the baffle plate 5 does not coincide with the first sub-hole 4 most of the time during the stirring process, impurities and water have enough time to be fully mixed in the housing 1 to form a uniform mixed liquid. In this way, when draining water and impurities, it can ensure that the impurity content in the discharged mixed liquid is relatively stable, avoiding problems such as incomplete discharge of impurities or uneven concentration of the discharged liquid caused by premature or too rapid drainage, improving the effect of impurity cleaning, and further ensuring the water quality and water storage capacity of the reservoir.

[0029] Further, a floating member 14 is slidably sleeved on the rotating shaft 10, a height sensor 15 is provided on the floating member 14, and the height sensor 15 is signal-connected to the motor 9 and the water outlet mechanism 3.

[0030] During the operation of the environmental protection reservoir in water conservancy projects, the amount of water injected into the housing 1 by the water inlet mechanism 2 each time is fixed and the same, for example, set to 20 tons (the ton here is for the convenience of exemplifying the concept of the amount of water corresponding to the liquid level). When there is no impurity precipitation at the bottom of the housing 1, the liquid level reaches the height corresponding to 20 tons of water after the first injection. However, over time, the impurities in the water precipitate to the bottom wall of the housing 1, which causes that when the water outlet mechanism 3 extracts water, due to the precipitated impurities occupying a certain space at the bottom of the housing 1, the actual amount of water that can be extracted is less than the originally supposed 20 tons. After repeating the water injection and pumping operations many times, each time 20 tons of water is injected, due to the accumulation of impurity precipitation, the liquid level will gradually be higher than the previous liquid level, and shows a trend of getting higher each time.

[0031] The floating member 14, such as a floating plate or an airbag, is arranged on the liquid surface inside the housing 1 and can float up and down with the rise and fall of the liquid surface. Since the height sensor 15 is provided on the floating member 14 and the height sensor 15 is signal-connected to the motor 9 and the water outlet mechanism 3, when the liquid level rises to a preset first preset height, the height sensor 15 will detect this liquid level change and transmit the signal to the water outlet mechanism 3. At this time, the water outlet mechanism 3 can normally perform the water extraction operation.

[0032] As the water outlet mechanism 3 continuously pumps water, the liquid level gradually drops. When the liquid level drops to the second preset height, the height sensor 15 detects the liquid level change again and transmits a signal to the motor 9 and the water outlet mechanism 3. At this time, the water outlet mechanism 3 stops the pumping operation, and at the same time, after receiving the signal, the motor 9 starts and enters the impurity removal process. During the whole process, the rotating shaft 10 plays a limiting role on the floating member 14, preventing it from moving randomly when floating up and down on the liquid surface, and the rotation of the rotating shaft 10 itself will not drive the floating member 14 to rotate, so as to ensure that the height sensor 15 can accurately monitor the liquid level change and realize the corresponding control function.

[0033] The above settings have the following effects: First, by setting the floating member 14 and the height sensor 15 and establishing a signal connection with the water inlet mechanism 2, the water outlet mechanism 3 and the motor 9, accurate monitoring and automatic control of the liquid level in the reservoir are realized. It can accurately judge the impurity precipitation situation and water use status in the reservoir according to the liquid level change, without the need for manual frequent checking of the liquid level and judgment of when to carry out impurity removal and other operations, greatly improving the automation degree of the reservoir operation and reducing the manual management cost. Second, based on the liquid level change, the pumping of the water outlet mechanism 3 and the start of the motor 9 for impurity removal are controlled, so that the two links of water use and impurity removal can be reasonably coordinated. On the premise of ensuring normal water use requirements, when the liquid level reaches a certain height and may affect subsequent water use due to impurity precipitation, impurity removal operations are carried out in a timely manner, avoiding problems such as reduced water storage capacity and deteriorated water quality caused by excessive accumulation of impurities, and at the same time ensuring that each pumping can be carried out within a reasonable liquid level range, improving the utilization efficiency of water resources. Third, this automatic control method according to the liquid level helps to protect related equipment. For example, it avoids excessive energy consumption or blockage and other failures of the water outlet mechanism 3 during pumping due to excessive impurities, and at the same time can prevent the motor 9 from starting frequently when it is unnecessary, extending the service life of the equipment and ensuring the stable operation of the entire water conservancy project environmental protection reservoir device.

[0034] Exemplarily, the floating member 14 is set as a floating plate or an airbag.

[0035] Further, a bearing is fixedly connected to the rotating shaft 10, and a bearing plate 16 is provided on the bearing for supporting the floating member 14 to prevent the floating member 14 from colliding with the blade 11 and preventing the floating member 14 from being driven to rotate when the rotating shaft 10 rotates. Specifically, a guide rod can also be provided at the lower end of the carrier 8, and a guide sleeve can be provided on the floating member 14, and the guide rod is inserted into the guide sleeve, thereby restricting the rotation of the floating member 14. The advantage is to prevent the hose 32 from being wound.

[0036] Further, the water outlet mechanism 3 includes a fixed pipe 31, a flexible pipe 32, and a water pump 33; the fixed pipe 31 is fixedly connected to the carrier 8, the outer end of the fixed pipe 31 communicates with the water pump 33, the inner end of the fixed pipe 31 communicates with the flexible pipe 32, and the other end of the flexible pipe 32 is installed on the floating member 14.

[0037] When the environmental protection reservoir in the water conservancy project is in operation, the liquid level will change with the injection or extraction of water. In the initial state, the floating member 14 is near the water surface, and the part of the flexible pipe 32 connected to it naturally hangs down. When water is injected into the housing 1, the liquid level rises, and the floating member 14 moves upward under the action of buoyancy. Since one end of the flexible pipe 32 is installed on the floating member 14, the flexible pipe 32 will be pulled up as the floating member 14 rises; conversely, when the water level in the housing 1 drops, the floating member 14 drops, and the flexible pipe 32 also drops accordingly. When the water pump 33 is started for pumping operation, the water pump 33 extracts water through the channel formed by the fixed pipe 31 and the flexible pipe 32. Since the other end of the flexible pipe 32 is connected to the floating member 14 and is always near the water surface with it, the water pump 33 always extracts the liquid on the upper layer of the water surface during the working process. Regardless of how the liquid level fluctuates, the flexible pipe 32 can adjust its own posture according to the position change of the floating member 14, ensuring that the pumping point is always located in the upper layer of the water body, effectively isolating the bottom sediment area.

[0038] Through the above settings, the following effects are achieved: First, through the cooperation of the flexible pipe 32 and the floating member 14, the upper clean liquid is accurately extracted, avoiding the bottom sediment from being pumped into the pumping system. This characteristic greatly reduces the content of impurities in the water, ensuring that the extracted water has a high cleanliness and can be directly used for various water conservancy project purposes with high water quality requirements, such as reducing the blockage of soil pores by sediment when irrigating crops and avoiding the damage of production equipment by impurities in industrial production. At the same time, preventing sediment from entering equipment such as the water pump 33 reduces the probability of equipment failures such as wear and blockage, extends the service life of the equipment, and reduces the equipment maintenance cost. Second, the design of the flexible pipe 32 part endows the pumping system with excellent liquid level adaptability. Under different water level conditions, whether it is the liquid level rising stage during the water storage process or the liquid level dropping stage during the water use process, the pumping system can operate stably and always maintain the effective extraction of the upper liquid. This flexibility ensures that under the actual working conditions of the dynamic change of the liquid level in the water conservancy project reservoir, the pumping operation can be carried out continuously and stably, without being interrupted or affecting the pumping effect due to the liquid level fluctuation, improving the reliability and continuity of the operation of the entire water conservancy project. Preferably, when the water outlet mechanism 3 is pumping water and the floating member 14 does not drop, it means that the floating member 14 has dropped to the upper surface of the sediment, and the height sensor 15 controls the water outlet mechanism 3 to close, which can prevent the suction of impurities.

[0039] Further, the housing 1 includes a drain pan 17. An installation hole is provided on the bottom wall of the housing 1, and the drain pan 17 is installed in the installation hole. A rubber sealing ring is provided at the outer edge of the drain pan 17, and the first sub-hole 4 is located on the drain pan 17. The drain pan 17 includes an upper plate and a lower plate, and there is a cavity between the upper plate and the lower plate. The baffle plate 5 is located in the cavity. A connecting ring 18 is fixedly connected to the lower side of the bottom wall of the housing 1, and a connecting ring 19 is fixedly connected below the lower plate. The connecting ring 19 and the connecting ring 18 are connected by bolts.

[0040] An installation hole is provided on the bottom wall of the housing 1 for installing the drain pan 17. The drain pan 17 is composed of an upper plate and a lower plate, and a cavity structure is formed between the two, which is used to accommodate the baffle plate 5. During installation, the drain pan 17 is in close fit with the installation hole by means of the rubber sealing ring at the outer edge, ensuring good sealing performance and preventing water from leaking from the installation gap between the drain pan 17 and the bottom wall of the housing 1. This sealing design not only ensures the overall water tightness of the reservoir, avoids waste of water resources, but also prevents adverse effects such as the surrounding foundation being soaked due to leakage, maintaining the stability of the reservoir structure and the normal surrounding environment.

[0041] The inner connecting ring 19 fixed below the lower plate is connected to the outer connecting ring 18 fixed to the lower side of the bottom wall of the housing 1 by bolts, realizing the firm fixation of the drain pan 17 on the bottom wall of the housing 1. This connection method is not only convenient for the installation, disassembly and maintenance of the drain pan 17. When the drain pan 17 is damaged or components such as the internal baffle plate 5 need to be maintained and replaced, it can be easily operated; but also can withstand the acting forces such as water pressure and water flow impact during daily operation, ensuring the stable position and complete structure of the drain pan 17.

[0042] When the motor 9 is started, the rotating shaft 10 drives the blade 11 to stir the sediment impurities at the bottom of the housing 1 to form a mixed liquid. At the same time, the connecting shaft 6 is driven to rotate through gear transmission, and the connecting shaft 6 drives the baffle plate 5 located in the cavity of the drain pan 17 to rotate. Since a number of first sub-holes 4 are provided on the drain pan 17 and are distributed in an annular array, and there are corresponding second sub-holes 7 on the baffle plate 5. During the rotation of the baffle plate 5, when at least part of the sub-holes of the two coincide, under the push of the water pressure in the housing 1 and the remaining power of the blade 11 stirring, the water mixed with impurities is discharged from the overlapping part of the holes through the drain pan 17 out of the housing 1, realizing the impurity cleaning work. The discharged impurities can be guided to a special treatment area through the subsequent drainage channel to avoid polluting the surrounding environment.

[0043] With the above settings, the following effects are achieved: First, the closely-fitted mounting hole design of the rubber sealing ring effectively solves the possible water leakage problem at the connection between the drainage tray 17 and the bottom wall of the housing 1, maintains the water storage capacity of the reservoir, and ensures the water supply stability of the water conservancy project. Especially under the long-term water storage operation condition, it avoids negative conditions such as water loss and pool wall erosion caused by the accumulation of minute leakage. Second, the bolt connection method between the inner connecting ring 19 and the outer connecting ring 18 makes the drainage tray 17 and the housing 1 a stable whole, which can resist the acting forces caused by the full water, drainage of the reservoir and external environmental factors such as wind load and vibration, prevent the drainage tray 17 from loosening and shifting, ensure the continuous normal operation of functional components such as impurity drainage, reduce the maintenance frequency, and extend the overall service life of the device. Third, the modular design of the drainage tray 17, which is composed of an upper tray and a lower tray combined and detachably connected, and the relatively independent and stable installation method with the housing 1 greatly facilitates the subsequent operation and maintenance work. When key impurity drainage components such as the baffle 5 and the connecting shaft 6 inside the drainage tray 17 fail, or the drainage tray 17 itself is damaged due to corrosion, wear, etc., the staff can conveniently disassemble the drainage tray 17, precisely repair and replace the internal components, reduce the operation and maintenance difficulty and cost, shorten the shutdown maintenance time, and ensure the efficient operation of the water conservancy project. Fourth, the first sub-hole 4 is arranged on the drainage tray 17, and the baffle 5 is placed in the cavity space of the drainage tray 17, optimizing the water flow path and spatial layout of impurity drainage. It makes the mixture of impurities and water drain more smoothly and efficiently, and is concentrated to drain out of the housing 1 through the drainage tray 17 in an orderly manner, preventing the impurities from remaining and accumulating disorderly in the housing 1, improving the thoroughness of each impurity drainage, continuously ensuring the effective water storage capacity and good water quality of the reservoir, and meeting the environmental protection and stable operation requirements of the water conservancy project.

[0044] Furthermore, a limiting ring 20 is fixedly connected to the upper tray, and the lower end of the rotating shaft 10 is inserted into the limiting ring 20. Through this setting, the limiting ring 20 can limit the rotating shaft 10 to prevent the rotating shaft 10 from tilting.

[0045] The working principle of the present invention: During the normal operation of the environmental protection reservoir in the water conservancy project, water enters the interior of the housing 1 through the water inlet mechanism 2. As time goes by, impurities in the water (such as sediment, suspended particles, etc.) gradually settle to the bottom wall of the housing 1 under the action of gravity. And when it is necessary to use the water, the water in the housing 1 can be pumped out through the water outlet mechanism 3. When it is necessary to clean the precipitated impurities, the motor 9 on the carrier 8 is started, and the output end of the motor 9 drives the rotating shaft 10 to rotate, and the blades 11 on the rotating shaft 10 rotate at high speed accordingly. During the rotation of the blades 11, the precipitated impurities at the bottom of the housing 1 are disturbed, so that the impurities are fully mixed with the surrounding water to form a mixed liquid with a higher impurity content. Since a number of first sub-holes 4 are arranged in an annular array on the bottom wall of the housing 1, and a rotatable retaining disc 5 is arranged at the bottom wall of the housing 1, and a number of second sub-holes 7 are arranged in an annular array on the retaining disc 5. When the motor 9 drives the rotating shaft 10 to rotate, the retaining disc 5 is rotated. When at least part of the second sub-holes 7 coincides with the first sub-holes 4, under the push of the water pressure in the housing 1 and the power generated by the stirring of the blades 11, the water mixed with impurities is discharged from the overlapping part of the holes out of the housing 1, realizing the cleaning work of the impurities. The discharged impurities can be transported to a special treatment area through subsequent drainage pipes or channels to prevent pollution to the surrounding environment.
