Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower engineering, in particular to a deep-water ground anchor connection device and a connection method. Background Art

[0002] Large reservoirs experience temperature stratification. If the water intake of a power station is located at a low elevation, low-temperature water will be discharged during the spring-summer transition due to power generation. This can easily cause a series of serious ecological problems downstream, such as affecting fish reproduction and leading to the extinction of some aquatic species. To address this phenomenon, a water barrier can be installed across the entire river section in front of the power station's water intake. Since the low-temperature water in the lower and middle parts of the reservoir is blocked by the barrier, the normal-temperature water at the surface of the reservoir passes through the top of the barrier, thereby raising the temperature of the water discharged from the power station and reducing the adverse impact of low-temperature water on the downstream ecology.

[0003] The watertight curtain wall bears a huge load, which needs to be transferred to the pontoon on the water surface and the ground anchor at the bottom of the reservoir through the cable net structure. Therefore, ensuring a reliable connection between the ground anchor and the longitudinal cables of the cable net structure is a key factor for the success of the project.

[0004] Underwater anchoring projects typically rely on divers to connect the anchors to the longitudinal cables of the cable net structure. However, for high dams and large reservoirs, the maximum water depth reaches 200 meters, making them deepwater anchoring projects. Conventional air diving has a maximum safe depth of only 60 meters, making conventional diving methods incapable of completing deepwater anchor connections. Saturation diving, a method used in marine engineering, can accomplish this task, but it is expensive, requires bulky specialized equipment, is difficult to transport inland, and is considered a high-risk operation. Experiments have also shown that using underwater robots (ROVs) to replace divers is a viable option. However, due to their limited operational flexibility and adaptability to underwater currents, this approach offers a limited guarantee of effective connections.

[0005] When connecting and installing the longitudinal cables of the watertight curtain wall to the deepwater anchors, the curtain needs to be lowered along with the cable net structure. This process presents complex working conditions and a short installation period. Currently, no mature and reliable technical solution has been developed to accomplish this connection. To achieve the project goals, a fast, effective, and reliable deepwater anchor connection device was required to complete the underwater connection between the longitudinal cables of the watertight curtain wall and the anchors. Summary of the Invention

[0055] To further clarify the objectives, technical solutions, and advantages of the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be described clearly and completely below, in conjunction with the accompanying drawings of the embodiments. It should be noted that the described embodiments represent only a portion of the embodiments of the present invention, and not all of them. Based on the described embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features therein may be combined with each other, unless otherwise defined. Unless otherwise defined, technical or scientific terms used in the present invention should have the same meanings as those commonly understood by persons of ordinary skill in the art to which the present invention pertains. The terms "first," "second," and similar expressions used in the present invention do not denote any order, quantity, or importance, but are used only to distinguish between different components. The terms "include," "comprising," and similar expressions mean that the elements or objects preceding the term include the elements or objects listed after the term, and their equivalents, without excluding other elements or objects.

[0056] At least one embodiment of the present invention provides a deep water anchor connection device, such as Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, it includes a male end connector 11, a female end connector 12, a locking assembly 13, a tightening assembly 14, and a traction rope 7. The lower part of the female end connector 12 is provided with a cavity structure 124, and the locking assembly 13 and the tightening assembly 14 are both arranged in the cavity structure 124.

[0057] The female connector 12 is plug-connected to the upper end of the male connector 11 through the cavity structure 124, and the load is transferred through the movable block 133 of the locking assembly 13, and is fixed at the same time. The tightening assembly 14 further locks the male connector 11 to ensure that the connection between the male connector 11 and the female connector 12 is reliable. The female connector 12 and the male connector 11 are both provided with rope grooves (123, 1132) for the traction rope 7 to pass through; the lower end of the male connector 11 is provided with a joint 114 for connecting to the ground anchor 8, and the upper end of the female connector 12 is connected to the longitudinal rope 4 through a connecting assembly. The connecting assembly includes a shackle 2 and a ring 3.

[0058] Figure 6What is shown is the main view of the male end connector. The upper end of the male end connector 11 is provided with a connecting head 111, and the connecting head 111 is a truncated cone structure 1111 or a conical structure with a cross section that is small at the top and large at the bottom, which is convenient for positioning and centering the male end connector 11 and the female end connector 12. When it is squeezed and matched with the arc surface 1333 on the outer side of the movable block 133 of the locking assembly 13, it can ensure that the movable block 133 does not self-lock due to friction, and the movable block 133 can be smoothly returned to the slide groove 125 when squeezed. The lower end face of the connecting head 111 is an annular bearing surface 1112, and the annular bearing surface 1112 is perpendicular to the axis of the male end connector 11. An annular groove 1113 is provided on the annular bearing surface 1112. Correspondingly, a convex body 1334 is provided at the corresponding position on the upper surface of the slider 1332 of the locking assembly 13. The cross-sectional shape of the annular groove 1113 matches the cross-sectional shape of the convex body 1334. Figure 5 As shown, when the male end connector 11 and the female end connector 12 are connected, the protrusion 1334 is embedded in the annular groove 1113 to prevent the movable block 133 from returning to the slide groove 125 after the first spring 132 fails, thereby realizing self-locking of the deep-water anchor connection device 1 and further improving the connection reliability of the device.

[0059] In this embodiment, an annular groove 1113 is provided on the annular bearing surface 1112, and a protrusion 1334 is provided at a corresponding position on the upper surface of the slider 1332. The two are matched and tightly locked to achieve self-locking of the device. In other embodiments, a protrusion may be provided on the annular bearing surface, and an annular groove may be provided at a corresponding position on the upper surface of the slider. The cross-sectional shapes of the protrusion and groove are not limited to semicircular, rectangular, triangular, etc.

[0060] Combine Figure 10 、 Figure 11 The axis of the rope threading groove on the male connector 11 is J-shaped. The rope threading groove enters from the top of the male connector 11 along the axis and exits from the side of the middle or lower part of the male connector 11. Specifically, the male connector 11 includes a baffle 112 and a rope guide block 113. The rope guide block 113 is fixed to the rope guide block mounting hole at the lower part of the male connector 11 via the baffle 112 and bolts. For ease of manufacturing, the rope guide block 113 is split, composed of two symmetrical half rope guide blocks 1131. An arcuate half rope groove 133 is machined into each half rope guide block 1131. When the two half rope guide blocks 1131 are combined, a complete arcuate rope groove is formed. Together with the straight rope groove inside the male connector, it forms a "J"-shaped rope threading groove 1132, reducing the difficulty of manufacturing the rope threading groove.

[0061] Figure 7The figure shows the front view of the female connector. The upper part of the female connector 12 is provided with two ear plates 121, and an ear plate clamping groove 122 is formed between the two ear plates 121. The lower part of the female connector 12 is provided with a cylindrical cavity structure 124. The bottom of the cavity structure 124 is a trumpet opening 126, which is convenient for centering and connecting with the connecting head 111 of the male connector 11. A plurality of slide grooves 125 are radially opened in the middle position of the cavity structure 124, and the movable block 133 of the locking assembly 13 can slide radially in the slide groove 125. The female connector 12 is provided with a rope threading groove 123 for passing the traction rope 7.

[0062] Figure 8 The figure shows a cross-sectional view of the locking assembly. The locking assembly 13 includes a fixed seat 131, a first spring 132, a movable block 133, and a pull ring 134. The fixed seat 131 is mounted on the cavity structure 124, and the inner cavity of the fixed seat 131 is connected to the cavity structure 124 via the movable block 133. The first spring 132 is horizontally disposed within the fixed seat 131. One end of the movable block 133 is connected to the fixed seat 131 via the first spring 132, and the other end passes through the cavity structure 124. A circular hole is defined in the center of the fixed seat baffle 1311, which coincides with the center of the chute 125. The fixed seat 131 is fixedly connected to the outside of the chute 125 of the female connector 12 via bolts. A first spring 132 is positioned between the fixed seat baffle 1311 and a slider 1332. The movable block 133 comprises a connected polished rod 1331 and a slider 1332. The polished rod 1331 of the movable block 133 extends through the circular hole of the fixed seat baffle 1311, whereupon its end is threadedly connected to a pull ring 134. The slider 1332 of the movable block 133 can move radially within the chute 125 (i.e., horizontally as shown in the figure) under the action of elastic force or external force. A protrusion 1334 is formed on the upper surface of the slider 1332, and the outer end surface of the slider 1332 extending into the cavity structure 124 is a curved surface 1333. There are at least two groups of locking components 13 , and the two groups of locking components 13 are symmetrically arranged in the cavity structure 124 .

[0063] Figure 9The figure shows a cross-sectional view of the tightening assembly. The tightening assembly 14 is located at the top of the cavity structure 124 and comprises a first sleeve seat 141, a second sleeve seat 144, and a second spring 142. The end surface of the seat plate of the first sleeve seat 141 is fixed to the upper surface of the cavity structure 124. The first sleeve seat 141 and the second sleeve seat 144 are sleeved together. The second spring 142 is sleeved around the outer rings of the sleeves of the first and second sleeve seats 141, 144 and positioned between the end surfaces of the seat plates of the first and second sleeve seats 141, 144. The first and second sleeve seats 141, 144 can move axially relative to each other within a certain range and generate a corresponding axial tightening force. A stop screw 143 is provided on the side of the sleeve of the first sleeve seat 141, and a stop slot is provided on the side of the sleeve of the second sleeve seat 144. The screw head of the stop screw 143 is retained in the stop slot. When the connection is completed, the tightening assembly 14 is squeezed to generate an axial tightening force, thereby offsetting the weight of the component, so that the annular bearing surface 1112 of the male end connector 11 and the bearing surface 1335 on the movable block 133 are always tightly fitted, thereby improving the reliability of the device connection.

[0064] Based on the same inventive concept, the present invention also proposes a deep-water anchor connection method, comprising the deep-water anchor connection device as described above, combined with Figure 1 , including the following steps:

[0065] S1. Pass the traction rope 7 through the "J"-shaped rope threading groove 1132 on the male end connector 11. The male end connector 11 is connected to the anchor 8 at the bottom of the reservoir through the joint 114 at its bottom. The upper end of the male end connector 11 is exposed above the riverbed 9. The two ends of the traction rope 7 are temporarily fixed to the buoyancy tank 5 on the water surface.

[0066] S2. When it is necessary to connect the longitudinal cable 4 of the water-blocking curtain wall with the ground anchor 8 at the bottom of the reservoir, the lower end of the longitudinal cable 4 is connected to the ear plate 121 of the female end connector 12 through the ring 3 and the shackle 2. The traction rope 7 passing through the top of the male end connector 11 is further passed through the rope threading groove 123 on the female end connector 12. The rope end of the traction rope 7 is braided to form an eyelet 71 and is sleeved on the shackle pin in the ear plate clamping groove 122.

[0067] S3. Use a winch to pull the other end 72 of the traction rope 7 upward at an appropriate speed, and at the same time release the longitudinal rope 4 downward at a corresponding speed, so that the traction of the traction rope 7 causes the trumpet opening 126 of the lower cavity structure 124 of the female end connector 12 to reach the vicinity of the upper portion of the male end connector 11;

[0068] S4. Under the pulling force of the traction rope 7, the male connector 11 and the female connector 12 are automatically aligned, and the male connector 11 located at the bottom is inserted into the cylindrical cavity structure 124 of the female connector 12. By squeezing the locking assembly 13, the movable block 133 is retracted into the slide groove 125, and the pressing assembly 14 is squeezed to reach the predetermined position. The movable block 133 of the locking assembly 13 automatically rebounds under the action of the first spring 132, and then the pulling force of the traction rope 7 is released to relax it. The pressing assembly 14 presses the annular bearing surface 1112 of the male connector 11 to the movable block 133, and the protrusion 1334 on the bearing surface of the movable block 133 is embedded in the annular groove 1113 of the male connector 111, thus completing the underwater connection between the waterproof curtain wall longitudinal cable 4 and the ground anchor 8, and realizing the self-locking of the deep-water ground anchor connection device.

[0069] The structural dimensions of the deepwater ground anchor connection device of the present invention are determined by the load it is designed to withstand. For example, when the device is designed to withstand a load of 50 tons, the maximum overall dimensions of the device (after connection) are 0.5m × 0.5m × 1.3m, which is suitable for deepwater reservoirs with depths of 120 to 180 meters. For large reservoirs, especially deep ones, 20 to 40 deepwater ground anchor connection devices are required at the bottom of the entire watertight curtain wall. The number of deepwater ground anchor connection devices is determined by a combination of factors, such as the reservoir depth, the width of the watertight curtain wall, and the load it is designed to withstand.

[0070] The deepwater ground anchor connection device and method of the present invention feature simple assembly and convenient operation. The male and female connectors are precisely positioned during connection, resulting in efficient installation and reliable connection. The device can be quickly connected underwater to the longitudinal cable of a water-blocking curtain wall and a deepwater ground anchor simply by inserting the male connector into the female connector using a towing rope operated above water. The deepwater ground anchor connection device of the present invention is suitable for connecting water-blocking curtain walls and ground anchors in deepwater reservoirs with a maximum water depth of 200 meters, and exhibits strong underwater adaptability.

[0071] The contents illustrated in the above embodiments should be understood as these embodiments are only used to more clearly illustrate the present invention, and are not used to limit the scope of the present invention.
