Description

Technical Field

[0001] This utility model relates to the field of underwater engineering technology, and in particular to a bottom anchor block for an oxygenation device that effectively improves the stability of the oxygenation device in water. Background Technology

[0002] As crucial water resource management and flood control projects, reservoirs inevitably impact the surrounding ecological environment during their construction and operation. Enclosed water bodies like reservoirs and freshwater lakes are prone to vertical thermal stratification, hindering the downward transfer of oxygen from the upper water layers and resulting in poor water flow. Simultaneously, the deep water layers remain chronically oxygen-deficient, accelerating the release of endogenous pollutants from bottom sediments, leading to water quality deterioration. Therefore, in the remediation of deep water bodies, reoxygenation, fluid flow field optimization, and suppression of pollutant release from bottom sediments are key.

[0003] Existing technologies for treating enclosed water bodies include enhanced natural remediation, sediment dredging, and in-situ covering. Enhanced natural remediation, particularly through artificial reoxygenation, involves introducing air or pure oxygen into the water. Dissolved oxygen reacts with black and odorous substances at the bottom of the water body via an oxidation-reduction reaction, thus inhibiting the release of pollutants from the sediment. Enhanced natural remediation includes methods such as water aeration and reoxygenation, artificial addition of biological agents, and ecological restoration. Water aeration and reoxygenation, in particular, helps accelerate the restoration of the aquatic ecosystem to a normal state, offering good results and relatively low investment and operating costs. In recent years, deep-water aeration and reoxygenation technologies (such as DWBZ reoxygenation technology) have gradually become the preferred technology in the field of deep reservoir remediation. By injecting oxygen into the bottom layer of the water, the reoxygenated water rises to the surface, promoting the exchange of water between the upper and lower layers of the deep reservoir and optimizing the flow field of the enclosed water body. This accelerates the decomposition of organic matter in the overlying water, purifying the water quality, while simultaneously oxidizing the anoxic sediment at the bottom, thereby inhibiting the release of pollutants from the sediment and achieving integrated sediment and water management.

[0004] Currently, when installing deep-water aeration and reoxygenation devices, it is necessary to fix the devices underwater to prevent them from shifting with the water flow. The traditional method is to use sink blocks for connection and fixation. A pulley is installed on the sink block, and a steel cable on the shore passes through the pulley and connects to the bottom of the reoxygenation device. This achieves underwater fixation of the reoxygenation device. When the water depth changes, the height of the reoxygenation device can be adjusted by raising and lowering the steel cable to meet the needs.

[0005] However, during use, because only one steel cable is connected to the reoxygenation device, the stability is poor. When the reoxygenation device is subjected to external force, it is prone to shaking, which affects the aeration effect. Summary of the Invention

[0006] The present invention aims to solve the problem that existing aeration and reoxygenation devices rely solely on a steel cable connected to the sinker, which leads to instability under external forces. It provides a reoxygenation device with a bottom anchoring sinker that effectively improves the stability of the reoxygenation device in water.

[0007] The underwater anchor block of this utility model for a reoxygenation device is characterized by having a connecting plate, pulley, rotating shaft, steel cable, winch, connecting rope, steering wheel, and fixing block. The fixing block is fixed to the bottom of the water, the connecting plate is horizontally positioned above the fixing block, and the steering wheel is fixed to the fixing block. Bearing seats are provided on both sides of the connecting plate, and the rotating shaft is horizontally mounted on the bearing seats. The pulley is fixed at the center of the rotating shaft, and the rotating shaft rotates with the pulley. The winch is divided into two groups, symmetrically fixed on the rotating shaft on both sides of the pulley, and the winch rotates with the rotating shaft. The connecting rope is positioned between the connecting plate and the reoxygenation device, with the upper ends of several connecting ropes fixed at equal intervals to the bottom of the reoxygenation device, and the lower ends fixedly connected to the winch one by one. The upper end of the steel cable is connected to the winch on shore, and the lower end passes through the steering wheel, then goes up and around the pulley on the connecting plate, and then hangs down to connect with the steering wheel. The surface of the steel cable is provided with raised strips, and the surfaces of the pulley and steering wheel are also provided with raised strips, with the raised strips on the steel cable matching the raised strips on the pulley.

[0008] The upper end of the steel cable is connected to a winch on the shore, and the length of the steel cable underwater is adjusted by pulling the steel cable with a motor.

[0009] At least four connecting cables are equidistantly connected to the bottom of the reoxygenation device, providing tension between the device and the connecting plate within a circumferential range. The stability of the reoxygenation device is greatly improved by the fixing blocks that are fixedly connected to the connecting plate. When the water level rises, the steel cable length is appropriately extended. After the steel cable is relaxed, the pulley, winch, and connecting cables are all in a relaxed state. When the reoxygenation device rises due to its own buoyancy, the connecting cables release an appropriate length to meet the device's buoyancy requirements. When the water level falls, the steel cable is tightened. During the tightening process, the steel cable is first released from the steering wheel, then passes around the pulley, and moves upwards from below the steering wheel to tighten. During this movement, the convex strips on the steel cable drive the pulley to rotate. When the pulley rotates, it drives the winch on the pulley to rotate via the shaft. The winch gathers the connecting cable wound on it, thus simultaneously tightening the connecting cable, reducing the height of the reoxygenation device, and allowing it to maintain an optimal working height.

[0010] The connecting plate has a groove in the middle, and bearing seats are set at both ends of the groove. The rotating shaft is installed in the bearing seats and located in the groove. This structure can effectively reduce the size of the connecting plate and reduce the impact of water flow on the rotating shaft and its transmission components.

[0011] The reoxygenation device of this invention features a bottom anchor block with a reasonable structure, scientific design, and convenient use. It is connected to the reoxygenation device at multiple points through a connecting plate and multiple connecting cables, which improves stability. The height of the reoxygenation device is adjusted synchronously using pulleys, a rotating shaft, and multiple winches to adapt to the water depth, thereby increasing the stability of the reoxygenation device during operation and improving its working efficiency.

[0016] Example 1: A reoxygenation device with an underwater anchor block. The anchor block is equipped with a connecting plate 1, a pulley 2, a rotating shaft 3, a steel cable 4, a winch 5, a connecting cable 6, a steering wheel 9, and a fixing block 7. The fixing block 7 is fixed to the bottom of the water. The connecting plate 1 is horizontally positioned above the fixing block 7, and the steering wheel 9 is fixed to the fixing block 7. Bearing seats 8 are provided on both sides of the connecting plate 1, and the rotating shaft 3 is horizontally mounted on the bearing seats 8. The pulley 2 is fixed at the center of the rotating shaft 3, and the rotating shaft 3 rotates with the pulley 2. The winch 5 is divided into two groups and symmetrically fixed to the pulley 2. On the two sides of the rotating shaft 3, the winch 5 rotates with the rotating shaft 3; the connecting cable 6 is set between the connecting plate 1 and the reoxygenation device, and the upper ends of several connecting cables 6 are fixed at equal intervals to the bottom of the reoxygenation device, and the lower ends are fixedly connected to the winch 5 one by one; the upper end of the steel cable 4 is connected to the onshore winch, and the lower end passes through the steering wheel 9 and then goes up to the pulley 2 on the connecting plate 1, and then hangs down to connect with the steering wheel 9; the surface of the steel cable 4 is provided with convex strips, and the surfaces of the pulley 2 and the steering wheel 9 are provided with convex strips, and the convex strips on the steel cable 4 match the convex strips on the pulley 2.

[0017] The upper end of steel cable 4 is connected to a winch on the shore. The motor pulls steel cable 4 to adjust its length underwater.

[0018] At least four connecting cables 6 are equidistantly connected to the bottom of the reoxygenation device, providing tension between the reoxygenation device and the connecting plate 1 within a circumferential range. The stability of the reoxygenation device is greatly improved by the fixing block 7, which is fixedly connected to the connecting plate 1. When the water level rises, the length of the steel cable 4 is appropriately increased. After the steel cable 4 is relaxed, the pulley 2, winch 5, and connecting cables 6 are all in a relaxed state. When the reoxygenation device floats up due to its own buoyancy, the connecting cables 6 release an appropriate length to meet the floating requirements of the reoxygenation device. When the water level drops, the steel cable 4 is tightened. During the tightening process, the steel cable 4 is first released from the steering wheel 9, then passes around the pulley 2, and then moves upwards from the bottom of the steering wheel 9 to tighten. During this movement, the protrusions on the steel cable 4 drive the pulley 2 to rotate. When the pulley 2 rotates, it drives the winch 5 on it to rotate through the rotating shaft 3. The winch 5 gathers the connecting cables 6 wound on it, thus simultaneously tightening the connecting cables 6, reducing the height of the reoxygenation device, and allowing the reoxygenation device to maintain an optimal working height.

[0019] A slot can also be provided in the middle of the connecting plate 1, and bearing seats 8 are provided at both ends of the slot. The rotating shaft 3 is installed in the bearing seats 8 and located in the slot. This structure can effectively reduce the size of the connecting plate 1 and reduce the impact of water flow on the rotating shaft 3 and its transmission components.
