Description

Technical Field

[0001] This invention relates to the field of hydropower technology, specifically to an adjustable lighting system for a wastewater treatment plant. Background Technology

[0002] Wastewater treatment plants can be seen as the "kidneys" of a city, responsible for purifying the dirty wastewater generated from domestic and industrial activities to meet the standards for safe discharge back into natural water bodies or reuse. Wastewater itself contains enormous energy, which can be recycled and converted into electricity through a series of technologies for the plant's own operation, especially lighting systems, thereby achieving energy conservation, emission reduction, and even "energy self-sufficiency."

[0003] For example, the patent document with authorization announcement number CN204511751U, authorization announcement date July 29, 2015, entitled "A Household Impact Water Bucket Type Sewage Power Generation and Lighting System," includes a sewage inlet, a sewage collection tank, a power generation unit, power transmission equipment, energy storage equipment, electrical equipment, and other related equipment. This system has a simple structure and clear hierarchy, representing the secondary development of water resources and improving water resource utilization efficiency.

[0004] In existing technologies, the sewage inlet direction is generally tangent to the turbine. In this case, if the sewage inlet path is too far from the center of the turbine, the sewage will fall to a position slightly above the turbine. In this case, the torque of the sewage impacting the turbine to drive it to rotate is small and cannot effectively drive the turbine to rotate. If the sewage inlet path is too far from the center of the turbine, some sewage will flow out directly without contacting the turbine. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable lighting system for wastewater treatment plants to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An adjustable lighting system for a wastewater treatment plant includes a lighting module and a power generation module. The power generation module includes a water turbine for generating electricity and a wastewater pipe disposed above the water turbine. Two water turbines are symmetrically arranged, and the wastewater pipe is located between the two water turbines. When the wastewater flows downward, it drives the two water turbines to rotate in opposite directions.

[0008] The aforementioned adjustable lighting system for a wastewater treatment plant includes a water turbine comprising a rotating shaft and several blades fixed on the rotating shaft.

[0009] The aforementioned adjustable lighting system for a wastewater treatment plant also includes a transfer chamber, in which both water turbines are rotatably connected.

[0010] In the aforementioned adjustable lighting system for a wastewater treatment plant, the blade tip is fitted to the inner wall of the transfer chamber.

[0011] The aforementioned adjustable lighting system for a wastewater treatment plant includes a drainage pipe installed at the bottom of the transfer room.

[0012] In the aforementioned adjustable lighting system for a wastewater treatment plant, a movable plate is slidably connected to the blade.

[0013] In the aforementioned adjustable lighting system for a wastewater treatment plant, the blades are provided with elastic elements for forcing the movable plate away from the rotating shaft.

[0014] In the aforementioned adjustable lighting system for a wastewater treatment plant, the movable plate is provided with movable strips, and the blades are provided with movable grooves, with the movable strips slidably connected within the movable grooves.

[0015] In the aforementioned adjustable lighting system for a wastewater treatment plant, as the blades on the two water turbines rotate synchronously and approach each other, the ends of the corresponding movable plates abut against each other, forcing the elastic element to deform until the two corresponding blades move away from each other, at which point the elastic element returns to its original position.

[0016] The aforementioned adjustable lighting system for a wastewater treatment plant also includes a transmission component for forcing two water turbines to rotate synchronously and in opposite directions.

[0017] In the above technical solution, the present invention provides an adjustable lighting system for a sewage treatment plant. When sewage is discharged from the sewage pipe, it can simultaneously impact two water turbines, so that the sewage flow path is as far away from the center of the water turbines as possible, and at the same time, it avoids sewage being discharged directly without contacting the water turbines. In this way, the power of the sewage is effectively used to rotate the two water turbines to generate electricity, thereby providing power to the lighting module. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figure 1-7 This invention provides an adjustable lighting system for a wastewater treatment plant, including a lighting module and a power generation module. The power generation module includes a water turbine 1 for generating electricity and a wastewater pipe 2 disposed above the water turbine 1. Two water turbines 1 are symmetrically arranged, and the wastewater pipe 2 is located between the two water turbines 1. When the wastewater flows downward, it drives the two water turbines 1 to rotate in opposite directions.

[0030] Specifically, in the sewage treatment process, sewage needs to flow between different treatment units by gravity or power. Thus, the water turbine 1 power generation structure can be installed on the sewage flow path, allowing the high-level sewage to impact the blades of the water turbine 1 at a high velocity, driving the water turbine 1 to rotate. This converts the mechanical energy of the rotating water turbine 1 into electrical energy to power the lighting module. The above are all existing technologies and will not be elaborated further. The innovation of this embodiment lies in that, in the power generation module, two symmetrically arranged water turbines 1 together receive sewage discharged from the same sewage pipe 2. The two water turbines 1 are equivalent to two horizontally symmetrical and tangent circular structures, and the path of the sewage discharged from the sewage pipe 2 is equivalent to a vertical straight line tangent to the two water turbines 1. This allows the sewage path to be as far away from the center of the water turbine 1 as possible, increasing the torque when driving the water turbine 1 to rotate, while minimizing sewage discharge without contacting the water turbine 1, thus maximizing the efficiency of sewage power generation.

[0031] In another embodiment of the present invention, the water turbine 1 further includes a rotating shaft 101 and a plurality of blades 102 fixed on the rotating shaft 101. Specifically, the rotating shaft 101 of the water turbine 1 is connected to an external generator set to generate electricity when the rotating shaft 101 rotates. This is prior art and is not shown in the figure, so it will not be described in detail here. The blades 102 are arranged in a ring array on the rotating shaft 101 so as to absorb the impact force of sewage through the blades 102, thereby driving the rotating shaft 101 to rotate.

[0032] Furthermore, it also includes a transfer chamber 3, in which both waterwheels 1 are rotatably connected. The ends of the blades 102 are in contact with the inner wall of the transfer chamber 3. A drain pipe 4 is provided at the bottom of the transfer chamber 3. Specifically, the inner wall of the transfer chamber 3 is smoothly formed, and the shafts 101 of both waterwheels 1 are rotatably connected to the inner wall of the transfer chamber 3 (a dynamic seal can be provided between the shafts 101 and the transfer chamber 3); the ends of the blades 102 are in contact with the inner wall of the transfer chamber 3. This arrangement allows sewage to remain on the blades 102 after impacting them, so that gravity can continue to force the shafts 101 to rotate; after the sewage flows down from the blades 102, it can continue to be discharged through the drain pipe 4 at the bottom of the transfer chamber 3.

[0033] In another embodiment of the present invention, a movable plate 5 is slidably connected to the blade 102. An elastic element 6 is provided on the blade 102 to force the movable plate 5 away from the rotating shaft 101. Specifically, the length of the movable plate 5 is the same as the length of the blade 102, that is, the ends of both the movable plate 5 and the blade 102 are attached to the inner wall of the transfer chamber 3; the movable plate 5 is slidably arranged along the width direction of the blade 102 (the sliding path is perpendicular to the axis of the rotating shaft 101); preferably, the movable plate 5 is provided with a movable strip 7, and the blade 102 is provided with a movable groove 8, the movable strip 7 being slidably connected within the movable groove 8. Both the movable groove 8 and the movable strip 7 are arranged along the width direction of the blade 102 (that is, the radial direction of the rotating shaft 101). This allows the movable plate 5 to slide along the movable groove 8 via the movable strip 7 (a protruding structure can be provided between the movable strip 7 and the movable groove 8 to limit the sliding stroke of the movable plate 5 and prevent the movable plate 5 from detaching from the blade 102 as much as possible; this is prior art and will not be elaborated further); the elastic element 6 can be a spring structure from the prior art, with one end fixed to the outer wall of the rotating shaft 101 and the other end fixed to the movable plate 5, so that the elastic element 6 can force the movable plate 5 to move to the extreme position away from the rotating shaft 101. In the above embodiment, only the ends of the two blades 102 that have rotated to the horizontal position between the two waterwheels 1 can abut against each other (e.g., Figure 1When the two blades 102 between the two rotating shafts 101 abut each other, a container can be formed between the two abutting blades 102, the two rotating shafts 101 and the inner wall of the transfer chamber 3 to collect sewage. This has the advantage that when the impact force of the sewage is small, the formed container can accumulate sewage and use the gravity of the sewage to drive the two water turbines 1 to rotate, further improving the efficiency of power generation when the sewage flow is small.

[0034] In this embodiment, a movable plate 5 and an elastic element 6 are provided on the blade 102 so that the movable plate 5 can move away from the blade 102 under the action of the elastic element 6. This is equivalent to extending the length of the blade 102. During the synchronous and counter-rotating process of the two water turbines 1, the corresponding water turbines 1 do not need to rotate to a horizontal position to achieve end connection through the movable plate 5, thereby forming multiple containers for collecting sewage. The water turbines 1 are then forced to rotate by the impact force of the sewage and then by the gravity of the sewage to generate electricity. The advantage is that, as Figure 3 As shown ( Figure 3 In the middle, elastic element 6 is not shown. Figure 4 (The elastic element 6 is shown in the figure). The three sets of connected movable plates 5 between the two water wheels 1 (one set of movable plates 5 is two symmetrical and corresponding movable plates 5) can all form a container for receiving sewage. Among them, the uppermost set of movable plates 5 can simultaneously utilize the impact force and gravity of the sewage, while the two sets of movable plates 5 below mainly utilize the gravity of the sewage, thereby forming a resultant force to drive the rotating shaft 101 to rotate.

[0035] With this configuration, as the blades 102 on the two water turbines 1 rotate synchronously and approach each other, the ends of the corresponding movable plates 5 abut against each other, forcing the elastic element 6 to deform until the two corresponding blades 102 move away from each other, at which point the elastic element 6 returns to its original position. Specifically, as shown... Figure 3 As shown, for the three sets of movable plates 5 between the two rotating shafts 101, the uppermost set of movable plates 5 receives the most kinetic energy from the sewage. Correspondingly, it needs to overcome the elastic force of the elastic element 6 so that the elastic element 6 stores elastic potential energy. After the set of movable plates 5 rotates to the horizontal position, the set of movable plates 5 begins to move away from each other, so that the gravitational potential energy of the sewage and the elastic potential energy of the elastic element 6 can be used together to force the rotating shaft 101 to rotate. In this way, the force situation of the multiple sets of movable plates 5 between the two rotating shafts 101 can be balanced, further improving the stability of the rotation of the two rotating shafts 101 to generate electricity.

[0036] Preferably, the system also includes a transmission assembly for forcing the two waterwheels 1 to rotate synchronously and in opposite directions. Specifically, the transmission assembly can be a gear set from the prior art. The gear set's transmission connection allows the two rotating shafts 101 to rotate synchronously and in opposite directions. This is prior art and is not shown in the figure, so it will not be described in detail here. This arrangement can ensure that the two waterwheels 1 rotate synchronously and in opposite directions as much as possible, so that the corresponding set of movable plates 5 can abut against each other at their ends when they move closer or further apart.

[0037] In another embodiment of the present invention, as an alternative to the above-mentioned transmission component, preferably, on the two corresponding movable plates 5, one movable plate 5 is provided with a connecting post 9, and the other movable plate 5 is provided with a locking mechanism for locking the connecting post 9. When the two corresponding movable plates 5 abut against each other, the locking mechanism operates to lock the connecting post 9, until the two movable plates 5 are about to separate, at which point the locking mechanism releases the locking of the connecting post 9. Specifically, for the movable plate 5 with the connecting post 9, an extension plate 15 is provided at the end away from the rotating shaft 101, and the connecting post 9 is fixed to the movable plate 5 through the extension plate 15; the locking mechanism can be an automatic latching structure in the prior art, so that the corresponding locking mechanism is triggered when the rotating shaft 101 rotates to the corresponding angle; for the two waterwheels 1, the movable plates 5 of one waterwheel 1 can both be provided with locking mechanisms, or both can be provided with connecting post 9 structures, or locking mechanisms and connecting post 9 structures can be provided alternately, so that corresponding locking can be achieved when the two waterwheels 1 rotate in opposite directions. The advantage of this configuration is that, in this embodiment, the transmission components of the above embodiments are omitted. By setting up the snap-fit ​​mechanism and the connecting column 9, the two water wheels 1 can snap into each other and rotate synchronously when rotating in opposite directions, achieving an effect similar to gear transmission. At the same time, the snap-fit ​​mechanism and the connecting column 9 can improve the sealing and stability when the two movable plates 5 are connected, and minimize the risk of the two movable plates 5 overcoming the elastic force of the elastic element 6 and shifting due to the impact force of sewage or gravity, and minimize the risk of sewage leaking out of the "receiving container".

[0038] Preferably, the locking mechanism includes an arcuate groove 10 constructed on the movable plate 5 and an arcuate plate 11 rotatably connected to the movable plate 5. The movable plate 5 is constructed with a sliding groove, and the inner wall of the sliding groove is constructed with an inclined groove 12. The end of the inclined groove 12 near the arcuate plate 11 is further away from the corresponding blade 102. A slider 13 is slidably connected in the inclined groove 12. The slider 13 and the movable strip 7 have the same thickness. When the slider 13 is located at the end of the inclined groove 12 away from the arcuate plate 11, the slider 13 protrudes from the movable strip 7. When the slider 13 is located at the end of the inclined groove 12 near the arcuate plate 11, the slider 13 is flush with the movable strip 7. A connecting rod 14 is hinged to the side of the slider 13 away from the movable strip 7. The other end of the connecting rod 14 is hinged to the arcuate plate 11. A torsion spring (not shown) is provided on the movable plate 5 to force the arcuate plate 11 closer to the blade 102, thereby forcing the slider 13 to be at the end of the inclined groove 12 away from the arcuate plate 11. Specifically, the arc-shaped groove 10 is constructed at the end of the movable plate 5 away from the rotating shaft 101, and the arc-shaped plate 11 is hinged at the end of the movable plate 5 away from the rotating shaft 101. The arc-shaped plate 11 has an open state and a closed state on the movable plate 5. In the open state, the arc-shaped plate 11 is away from the arc-shaped groove 10 so that the corresponding connecting post 9 can enter or leave. When the connecting post 9 is attached to the arc-shaped groove 10, the arc-shaped plate 11 switches to the closed state to lock the connecting post 9. At this time, the inner wall of the arc-shaped plate 11 is smoothly connected to the arc-shaped groove 10. At the same time, since the connecting post 9 is a columnar structure, the connecting post 9 can still rotate relative to the arc-shaped groove 10 and the arc-shaped plate 11 and maintain the locking after being locked (the arc-shaped groove 10 and the arc-shaped plate 11 form a "C" shape, and the angle of its surrounding of the connecting post 9 is greater than 180 degrees, so that the connecting post 9 is locked while rotating), so as to adapt to the rotation of the two movable plates 5.

[0039] The thickness of the chute and slider 13 is the same as the thickness of the movable bar 7 and the movable groove 8. The slider 13 is movably set in the chute so that it can slide along the inclined groove 12. The slider 13 and the arc plate 11 are connected by a connecting rod 14, so that the slider 13 can drive the arc plate 11 to switch states when sliding along the inclined groove 12. When the slider 13 moves to the end of the inclined groove 12 away from the arc plate 11, the arc plate 11 switches to the open state. When the slider 13 moves to the end of the inclined groove 12 close to the arc plate 11, the arc plate 11 switches to the closed state. In this embodiment, under the impact force and gravity of the sewage, the two water wheels 1 rotate. When the ends of the two opposing movable plates 5 abut, the two movable plates 5 overcome the elastic force of the elastic element 6 and approach the corresponding rotating shaft 101 due to the rotation of the shaft 101. During the process, the end of the blade 102 abuts against the slider 13 (because the slider 13 protrudes from the movable bar 7, such as...). Figure 6As shown), this forces the slider 13 to move along the inclined groove 12 to one end near the arc plate 11, so that the slider 13 is flush with the movable bar 7 and can enter the movable groove 8 with the movable bar 7. At this time, the arc plate 11 switches to the closed state, and then the two opposing movable plates 5 can remain engaged and rotate with the corresponding blades 102, and the slider 13 will not affect the sliding of the movable plate 5 on the corresponding blades 102 (as shown). Figure 7 As shown, the two blades 102 are in a horizontal state, and the slider 13 enters the movable groove 8 together with the movable bar 7. The diameter of the connecting rod 14 is smaller than the thickness of the movable groove 8, so that the connecting rod 14 also enters the movable groove 8 together with the slider 13, without affecting the sliding connection between the movable plate 5 and the blades 102.

[0040] The advantage of this arrangement is that, for the three sets of movable plates 5 between the two rotating shafts 101, the middle set of movable plates 5 will remain in a snap-fit ​​state to assist the other two sets of movable plates 5 in stably snapping or separating (e.g., Figure 5 As shown, there are three sets of movable plates 5 engaged between the two rotating shafts 101. The middle set is in a stable engaged state, the upper set has just finished engaging, and the lower set is about to disengage. This creates a gear-like transmission effect during the rotation of the two water wheels 1, so that the two water wheels 1 rotate synchronously and in opposite directions, while improving the connection and sealing between the two movable plates 5.

[0041] It should be noted that during the process of water turbine 1 rotating to generate electricity, the rotational speed of water turbine 1 is relatively low, and the centrifugal force has little impact on the state of arc plate 11.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
