[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] The gate 6 system grab beam 5 deep-water cable 3 fixing and compensation device of the embodiment of the present invention includes: a fixing component 1 and a compensation component 2, wherein the fixing component 1 is sleeved on the cable 3, one end of the compensation component 2 is connected to the fixing component 1, and the other end of the compensation component 2 is connected to the grab beam 5, and the compensation component 2 includes a first elastic component 21, one end of the first elastic component 21 is connected to the fixing component 1, and the other end of the first elastic component 21 is connected to the grab beam 5.

[0030] Specifically, Figures 1 to 4 As shown, the fixing component 1 is sleeved on the cable 3 to fix the fixing component 1 and the cable 3.

[0031] The upper end of the compensation component 2 is connected to the fixed component 1, and the lower end of the compensation component 2 is connected to the grab beam 5, and the grab beam 5 is connected to the gate 6 of the hydropower station. The gate 6 of the hydropower station moves in the up and down directions to open or close the gate.

[0032] The design of the compensation component 2 is intended to solve the relative displacement problem between the grab beam 5 and the cable 3 during the opening and closing of the gate 6. It is also caused by factors such as the movement of the gate 6, water flow impact or temperature change. For example, during the operation of the gate 6, the gate 6 moves downward, and the cable drum 4 above the gate 6 rotates to release a portion of the cable 3. During the operation of the original cable 3, the cable 3 released by the cable drum 4 has a large margin. For example, a 3-meter cable 3 margin is set. The excess cable 3 will be hung on the surrounding adjacent equipment under the influence of gravity and water flow impact. When the gate 6 moves up and down later, the cable 3 interferes with the surrounding equipment, causing the cable 3 to be damaged by excessive force or affecting the service life of the cable 3.

[0033] In the present application, when releasing the cable 3, the cable reel 4 can reduce the released margin of the cable 3. For example, the margin of the cable 3 can be set to 1 meter, or 50 cm, to cope with the change in the length of the cable 3 caused by temperature changes. At the same time, the reduction in the length of the cable 3 also reduces the probability of interference between the cable 3 and surrounding equipment, thereby increasing the service life of the cable 3.

[0034] At the same time, when the elastic component is in use, it is used to keep the cable 3 tight when the gate 6 moves up and down or the cable reel 4 collects the cable 3, so as to prevent the cable reel 4 from releasing and retracting the cable 3 unevenly when the gate 6 moves. When the cable 3 is released or reeled, the cable 3 is quickly fixed to prevent the cable 3 from swinging.

[0035] For example, when the cable 3 is subjected to a hard pulling force, the pulling force is first transmitted to the elastic component, and the elastic component is stretched to buffer the force when the cable reel 4 retracts the cable 3, thereby avoiding damage to the cable 3.

[0036] The gate 6 system grab beam 5 deep-water cable 3 fixing and compensating device of the embodiment of the present invention can quickly fix the cable 3, protect the cable 3 during the operation of the grab beam 5, extend the service life of the equipment, and reduce maintenance costs.

[0037] In some embodiments, the compensation component 2 further includes a limiting component 22, one end of the limiting component 22 is pivotally connected to an end of the first elastic component 21 adjacent to the fixing component 1, and the other end of the limiting component 22 is pivotally connected to an end of the first elastic component 21 adjacent to the grab beam 5.

[0038] Specifically, Figures 1 to 4 As shown, the upper end of the limiting component 22 is connected to the upper end of the first elastic component 21, the lower end of the limiting component 22 is connected to the lower end of the first elastic component 21, the lower end of the limiting component 22 is pivotally connected to the lower end of the first elastic component 21, and the limiting component 22 stretches or contracts in the up and down directions to limit the movement range of the first elastic component 21 in the up and down directions.

[0039] In some embodiments, the first elastic component 21 includes an elastic adjustment member 211, an elastic member 212 and a connecting plate 213, one end of the elastic adjustment member 211 is connected to the fixing assembly 1, the other end of the elastic adjustment member 211 is connected to one end of the elastic member 212, and the other end of the elastic member 212 is connected to the connecting plate 213 arranged on the grab beam 5.

[0040] Specifically, Figures 1 to 4As shown, the upper end of the elastic member 212 is connected to the upper end of the elastic force adjustment member 211, the lower end of the elastic member 212 is connected to the connecting plate 213, the connecting plate 213 is connected to the grab beam 5, and the elastic member 212 stretches or contracts in the up and down direction to keep the cable 3 tight when the gate 6 moves up and down or the cable reel 4 collects the cable 3. It is prevented that the cable reel 4 retracts and releases the cable 3 unevenly when the gate 6 moves. When the cable 3 is released or reeled, the cable 3 is quickly fixed to prevent the cable 3 from swinging.

[0041] The size of the elastic adjustment component in the up and down directions can change, for example, the elastic adjustment member 211 is extended to reduce the elastic force of the elastic member 212 when the cable 3 is released to the same position, or the elastic adjustment member 211 is contracted to increase the elastic force of the elastic member 212 when the cable 3 is released to the same position.

[0042] This makes it easier for on-site personnel to adjust the length of the elastic adjustment piece according to actual usage during installation or use.

[0043] Furthermore, the elastic member 212 is a spring, and the tension on the cable 3 is determined by the weight of the cable 3 when the gate 6 is closed, and the spring type is determined by the tension spring model specification comparison table. For example, when the gate 6 is closed, that is, when the gate 6 moves to the bottom, the maximum length of the cable 3 released by the cable drum 4 is determined, and then the gravity or weight of the cable 3 released by the cable drum 4 is determined, and a suitable spring type is selected according to the weight of the cable 3.

[0044] In some embodiments, the elastic adjustment member 211 includes a connecting line 2111, an outer tube 2112 and an inner tube 2113, one end of the connecting line 2111 is connected to the elastic member 212, the other end of the connecting line 2111 is connected to one end of the inner tube 2113, the other end of the inner tube 2113 is connected to the outer tube 2112, and the inner tube 2113 is provided with scale lines.

[0045] Specifically, Figures 1 to 4 As shown, the upper end of the connecting line 2111 is connected to the inner cylinder 2113, and the lower end of the connecting line 2111 is connected to the elastic member 212. The inner cylinder 2113 is threadedly connected to the outer cylinder 2112, and the size of the inner cylinder 2113 and the outer cylinder 2112 in the up-down direction after the connection can be changed by rotating the inner cylinder 2113. Then the tension of the elastic member 212 is adjusted, and the elastic member 212 can be an existing spring. The inner cylinder 2113 is provided with scale lines extending in the up-down direction, so that the operator can determine the size of the inner cylinder 2113 extending into the outer cylinder 2112 through the scale lines exposed by the inner cylinder 2113, and then determine the length of the inner cylinder 2113 and the outer cylinder 2112 in the up-down direction, so as to change the elastic force of the elastic member 212, and to adjust the tension of the gate 6 received by the elastic member 212 when it moves up and down.

[0046] In some embodiments, the limiting component 22 includes a first frame 221 and a second frame 221 hinged to each other, and a limiting frame 223, the limiting frame is hinged to the first frame 221, the limiting frame is provided with a plurality of first through holes 225 arranged at intervals along the extending direction of the first elastic component 21, and the bolt 224 passes through any one of the first through holes 225 and is connected to the second frame 221.

[0047] Alternatively, the limiting frame is hinged to the second frame 221 , and the limiting frame is provided with a plurality of first through holes 225 arranged at intervals along the extending direction of the first elastic component 21 , and the bolt 224 passes through any first through hole 225 to be connected to the second frame 221 .

[0048] The first through hole 225 is in a rectangular or elliptical shape.

[0049] Specifically, Figures 1 to 4 As shown, the upper end of the first frame 221 is pivoted to the fixing assembly 1, the lower end of the first frame 221 is pivoted to the upper end of the second frame 221, the lower end of the second frame 221 is pivoted to the connecting plate 213, the limiting frame is rotatably provided on the first frame 221 or the second frame 221, and the other end of the limiting frame is provided with a plurality of first through holes 225 arranged at intervals along the up-down direction, the bolt 224 can pass through any first through hole 225 to be connected to the second frame 221 or the first frame 221, and the bolt 224 can move in the up-down direction in the first through hole 225 passed through.

[0050] At the same time, when the bolt 224 moves to the upper end or the lower end of the first through hole 225, the first frame 221 and the second frame 221 no longer rotate to limit the elastic member 212 from being over-stretched or compressed, thereby avoiding damage to the elastic member 212. When the spring is compressed, the device is prevented from being damaged by pressure. When the spring is compressed to the limited position, the limit assembly is activated to avoid further compression and damage of the spring, thereby improving the stability and safety of the use of the elastic member 212.

[0051] The first frame 221 and the second frame 221 are integrally formed into a "<"-shaped hinge structure, and the hinge is flexible and can move in the vertical direction with the spring to avoid bending of the spring. At the same time, the limit device and the "<"-shaped hinge structure form a triangle to improve the structural stability of the device.

[0052] The compensation device of the embodiment of the present invention first transmits the pulling force to the spring when the cable 3 is subjected to hard pulling force, and the spring is stretched. When the pulling force continues to increase, the spring tension limiting device is activated before the spring tension reaches a limit, thereby avoiding damage to the cable 3; when the spring is compressed, the spring is prevented from being damaged by compression, that is, when the spring is compressed to the limiting position, the limiting component 22 is activated to avoid further compression and damage of the spring, thereby improving the stability and safety of the device.

[0053] In some embodiments, the number of the limiting components 22 is multiple, and the multiple limiting components 22 are coplanar and spaced apart. For example, multiple limiting components 22 are spaced apart in the front-to-back direction or the left-to-right direction, and the multiple limiting components 22 are coplanar, so as to improve the protection effect of the elastic member 212. For example, the number of the limiting components 22 is two, and the whole is a double <-shaped support hinge structure, the hinge is flexible, and can move in the vertical direction with the spring to avoid the spring from bending. At the same time, the limiting device and the "<"-shaped support hinge structure form a triangle, which improves the structural stability of the device.

[0054] In some embodiments, the fixing component 1 includes a clamping part 11 and a rubber pad 12, wherein the clamping part 11 is sleeved on the cable 3, and the rubber pad 12 is arranged between the cable 3 and the clamping part 11. The combination of the clamping part 11 and the rubber pad 12 enables the fixing component 1 to not only effectively fix the cable 3 and increase the stability of the connection between the fixing component 1 and the cable 3, but also provide additional buffering and protection through the elastic design of the rubber pad 12. The clamping part 11 can be an existing clamp, for example, a split clamp. The split clamp is used to fix the cable 3, and the material is a galvanized clamp, and the rubber pad 12 is attached to the inner wall, which protects the cable 3 and fixes it more firmly.

[0055] In some embodiments, a second elastic component is further included, one end of the second elastic component is connected to one end of the first frame 221 away from the second frame 221, and the other end of the second elastic component is connected to one end of the second frame 221 away from the first frame 221. The second elastic component may be an elastic rope, and when the elastic member 212 is damaged and cannot work, the elastic member 212 may be replaced to a certain extent, and the tension is first transmitted to the elastic rope when the cable 3 is subjected to hard tension, so as to facilitate the temporary use of the grab beam 5 and facilitate the subsequent operators to replace the elastic member 212 in time.

[0056] Furthermore, the material of the second elastic component is rubber to provide the necessary elasticity and compensation function. Rubber can undergo elastic deformation in a large range and quickly return to its original state after the external force is removed. This characteristic makes rubber an ideal material for compensating for the relative displacement between the cable 3 and the grab beam 5 caused by the operation of the gate 6 or environmental factors. The rubber material has good wear resistance and can maintain stable performance in a long-term underwater environment, reducing the risk of failure caused by friction and wear. Rubber has good corrosion resistance to a variety of chemical substances and water environments, and can maintain the stability of its physical and chemical properties in harsh underwater environments, thereby improving the stability and safety of the cable 3 using the compensation device.
