When the steel wire rope 12 and the crimping section 131 are crimped, the barb portion 1312 is pressed to hook the steel wire rope 12, thereby increasing the stability of the connection between the steel wire rope 12 and the crimping section 131.

[0064] Preferably, the shape of the crimping section 131 after crimping is a regular hexagon. The regular hexagon has the characteristics of symmetry and uniform force distribution, can withstand a large load, and alleviate the situation of excessive local force, thereby improving the stability of the overall structure of the crimping head 13, which is conducive to maintaining the stability of the connection.

[0065] The crimping joint 13 can increase the safety and stability of connecting the steel wire rope 12 to the water blocking member 2. The barb 1312 can be provided on the inner wall of the fixed cavity 1311 to hook the steel wire rope 12 under pressure when the steel wire rope 12 and the crimping section 131 are crimped, thereby increasing the stability of the connection between the steel wire rope 12 and the crimping section 131; the crimping section 131 has a regular hexagonal shape after crimping, which has a large bearing capacity, and can reduce stress concentration, withstand a large load, and alleviate the situation of excessive local stress, thereby improving the stability of the overall structure of the crimping joint 13, which is conducive to maintaining the stability of the connection.

[0067] This embodiment provides a method for fixing a steel wire rope used in the steel wire rope assembly described in Embodiment 1, using a crimping die 3, such as Figure 4 As shown, the following steps are included:

[0068] S1: Connect the wire rope 12 to the wire rope hub shaft 11;

[0069] S2: insert the end of the steel wire rope 12 into the fixing cavity 1311;

[0070] S3: crimping the steel wire rope 12 and the crimping section 131;

[0071] S4: Check the crimping quality;

[0072] S5: Install and secure the wire rope assembly.

[0073] In step S1 , specifically, the steel wire rope 12 is introduced into the steel wire rope hub shaft 11 , so that the steel wire rope hub shaft 11 cooperates with the steel wire rope 12 , and the retraction and extension of the steel wire rope 12 can be controlled by rotating the steel wire rope hub shaft 11 .

[0074] In step S2 , specifically, the crimping head 13 is connected to the steel wire rope 12 , so that the end of the steel wire rope 12 enters the fixing cavity 1311 .

[0075] Furthermore, step S3 specifically includes the following steps:

[0076] Step S31: placing the crimping section 131 on the crimping die 3;

[0077] Step S32: pressurizing the crimping section 131 .

[0078] like Figure 5 As shown, the crimping mold 3 includes a placing platform 31 and a pressurizing platform 32. A placing groove 311 is arranged on the placing platform 31, and the length of the placing groove 311 corresponds to the crimping section 131. A pressurizing groove 321 is arranged on the pressurizing platform 32. When the pressurizing platform 32 is pressed tightly against the placing platform 31, the pressurizing groove 321 cooperates with the placing groove 311 to form a regular hexagonal cavity.

[0079] In step S31 , specifically, the crimping section 131 is placed in the placement groove 311 .

[0080] In step S32, specifically, the pressurizing platform 32 is controlled by a hydraulic press to pressurize the crimping section 131, so that the pressurizing groove 321 cooperates with the placement groove 311 to pressurize the crimping section 131 into a regular hexagon at one time, so that the inner wall of the fixing cavity 1311 presses the wire rope tightly, and at the same time the barb portion 1312 hooks the wire rope 12 tightly.

[0081] By crimping the steel wire rope 12 and the crimping section 131, the inner wall of the fixed cavity 1311 can be pressed tightly against the steel wire rope, and at the same time, the barb portion 1312 can hook the steel wire rope 12, thereby increasing the stability of the connection between the steel wire rope 12 and the crimping section 131; the crimping section 131 after crimping is in a regular hexagon, has a large load-bearing capacity, and can reduce stress concentration, withstand large loads, and alleviate the situation of excessive local force, thereby improving the stability of the overall structure of the crimping head 13.

[0082] In step S4 , specifically, tension in opposite directions is applied to the steel wire rope 12 and the crimping section 131 according to the designed bearing capacity and safety factor of the steel wire rope 12 to test whether the steel wire rope 12 will fall off from the fixing cavity 1311 .

[0088] Furthermore, the control unit 4 includes a driving unit 41, a rotating shaft 42, a transmission unit 43 and a support member 44. The support member 44 is connected to the frame unit 5. The driving unit 41 and the transmission unit 43 are fixed on the support member 44. The driving unit 41 is connected to the rotating shaft 42 through the transmission unit 43. The rotating shaft 42 passes through the wire rope hub shaft 11 and is connected to the support member 44 through a bearing seat. The wire rope hub shaft 11 can rotate with the rotating shaft 42. The driving unit 41 can drive the rotating shaft 42 to rotate, thereby driving the wire rope hub shaft 11 to rotate, causing the wire rope 12 to be retracted and released, and driving the water blocking member 2 to move.

[0089] Furthermore, if Figure 7 As shown, the driving part 41 includes a motor 411, and the transmission part 43 includes a reducer 431. The reducer 431 is fixed on the support member 44. The rotating shaft of the motor 411 passes through the support member 44 and is connected to the reducer 431. The reducer 431 transmits the rotation of the rotating shaft to the rotating shaft 42, and drives the rotating shaft 42 to rotate through the rotation of the rotating shaft.

[0090] Preferably, Figure 7 As shown, the driving part 41 also includes a hand crank 412, and the transmission part 43 also includes a transmission box 432. The transmission box 432 is fixed in the support member 44. The rotating shaft of the motor 411 passes through the transmission box 432 and is connected to the reducer 431. The hand crank 412 passes through the support member 44 and is connected to the transmission box 432. When the motor 411 cannot work normally, rotating the hand crank 412 can drive the rotating shaft of the motor 411 to rotate through the transmission box 432, thereby driving the rotating shaft 42 to rotate.

[0091] By setting up a hand crank 412 and a transmission part 43, the water conservancy control device can realize both electric control and manual driving modes, so that the staff can remotely control the opening and closing of the water blocking member 2, and can also manually control the water blocking member 2 through the hand crank 412 according to the on-site conditions, thereby increasing the flexibility and convenience of operation. At the same time, the water blocking member 2 can be controlled when power is limited, providing emergency protection for the water conservancy control device and improving the safety of the water conservancy control device.

[0092] Furthermore, if Figure 8 As shown, the transmission box 432 includes an active member 4321, a driven member 4323 and a box body 4324. The box body 4324 is fixed in the support member 44. The active member 4321 and the driven member 4323 are arranged in the box body 4324. The active member 4321 is connected to the hand crank 412, and rotating the hand crank 412 can drive the active member 4321 to rotate; the driven member 4323 is connected to the rotating shaft of the motor 411, and the driven member 4323 can rotate with the active member 4321, thereby driving the rotating shaft of the motor 411 to rotate.

[0093] Exemplarily, the active member 4321 and the driven member 4323 are gears, and the active member 4321 is meshingly connected with the driven member 4323 .

[0094] Preferably, the transmission box 432 also includes a transmission connecting member 4322, and the active member 4321 is connected to the driven member 4323 through the transmission connecting member 4322. The transmission connecting member 4322 transmits the rotation of the active member 4321 to the driven member 4323, thereby increasing the length of the transmission box 432 and preventing the active member 4321 from being too close to the driven member 4323 to interfere with the movement of the hand crank 412.

[0095] Exemplarily, the active member 4321 , the transmission connection member 4322 and the driven member 4323 are all gears, and the active member 4321 and the driven member 4323 are both meshingly connected with the transmission connection member 4322 .

[0096] Exemplarily, the active member 4321 and the driven member 4323 are both pulleys, the transmission connection member 4322 is a transmission belt, and the active member 4321 drives the driven member 4323 to rotate via the transmission belt.

[0097] like Fig. 9 As shown, Figure 6As shown, the frame unit 5 includes a bottom frame 51 and a side frame 52, and the bottom frame 51 is connected to the side frame 52. The water blocking member 2 also includes a water blocking side plate 22 and a water blocking panel 23, and the water blocking panel 23 is movably connected to the bottom frame 51. The water blocking side plate 22 is arranged at both ends of the water blocking panel 23, and the connecting member 21 is arranged on the water blocking side plate 22. The water blocking side plate 22 can be pulled to move by the steel wire rope 12, so that the water blocking panel 23 rotates along the bottom frame 51 to control the water flow passing through the hydraulic water control device.

[0098] Furthermore, if Fig.10 As shown, the frame unit 5 further includes a water blocking layer 53 , which is disposed on the bottom frame 51 and the side frame 52 to prevent water from leaking from the gap between the water blocking member 2 and the frame unit 5 .

[0099] Preferably, Fig.11 As shown, the first protrusion 531 and the second protrusion 532 are arranged on the water-blocking layer 53, and the first protrusion 531 and the second protrusion 532 press the water-blocking side plate 22 or the water-blocking panel 23. By arranging the first protrusion 531 and the second protrusion 532, a two-way water-stopping effect can be achieved. The first protrusion 531 and the second protrusion 532 form a water-stopping horizontal plane, which increases the water-stopping area and can still maintain a stable sealing performance when subjected to a large water pressure.

[0100] Preferably, Fig.12 As shown, the frame unit 5 further includes a water level gauge placement portion 54, which is disposed in the side frame 52 and is used to place a water level gauge to measure the water level at the location of the hydraulic water control device.

[0101] Further, the water level gauge placement portion 54 includes a first placement cavity 541 and a second placement cavity 542, and the first placement cavity 541 and the second placement cavity 542 are used to place the water level gauge, so as to measure the water level on both sides of the water blocking member 2. When the water blocking member 2 is in the water blocking state, the first placement cavity 541 and the second placement cavity 542 are separated and arranged on both sides of the water blocking panel 23, and are not connected to each other. The water level gauge is placed in the first placement cavity 541 and the second placement cavity 542. The first protrusion 531 and the second protrusion 532 are arranged between the first placement cavity 541 and the second placement cavity 542, and the water blocking layer 53 is provided with a plurality of water inlet holes at positions corresponding to the first placement cavity 541 and the second placement cavity 542, and the water inlet holes are respectively connected with the first placement cavity 541 and the second placement cavity 542, and the water flow can enter the first placement cavity 541 and the second placement cavity 542 through the water inlet holes, so that the water level in the first placement cavity 541 and the second placement cavity 542 is the same as the water level of the water flow on the side. The water levels of the first placement cavity 541 and the second placement cavity 542 are respectively recorded by a water level meter, so as to measure the water levels on both sides of the hydraulic water control device.

[0102] The first placement cavity 541 and the second placement cavity 542 can provide a stable measurement environment for the water level meter, thereby reducing the influence of water flow fluctuations and impurities on the measurement results, and improving the accuracy and stability of water level measurement. The water flow through the hydraulic water control device can be calculated by calculating and analyzing the water level data of the first placement cavity 541 and the second placement cavity 542.

[0103] Example 4

[0104] This embodiment provides a hydraulic water control device, such as Fig.13 As shown, the difference from Example 3 is that no water inlet hole is set on the water blocking layer 53, and the frame unit 5 also includes a filter assembly 55, which is arranged at the bottom of the side frame 52. The position of the filter assembly 55 corresponds to the first placement cavity 541 and the second placement cavity 542, and is used to connect the external water flow with the first placement cavity 541 and the second placement cavity 542, and prevent impurities from entering the first placement cavity 541 and the second placement cavity 542 to affect the measurement accuracy of the water level meter.

[0105] like Figure 13-14 As shown, the filter assembly 55 includes a housing 551, a water inlet 552 and a water outlet 558. The housing 551 passes through the water-blocking layer 53 and is connected to the first placement cavity 541 or the second placement cavity 542. The water inlet 552 and the water outlet 558 are arranged on the housing 551. The position of the water inlet 552 is higher than the water outlet 558. Water flows into the housing 551 through the water inlet 552 and enters the first placement cavity 541 or the second placement cavity 542 through the water outlet 558. A filter screen is arranged on the water outlet 558 to filter the water flow entering the first placement cavity 541 or the second placement cavity 542.

[0106] Preferably, a sealing ring is provided between the shell 551 and the water blocking layer 53 to prevent water from flowing into the first placement cavity 541 or the second placement cavity 542 through the gap between the shell 551 and the water blocking layer 53 .

[0107] Furthermore, if Fig.14As shown, the filter assembly 55 also includes a hydraulic rotating member 553, a follower 554, a swinging member 555, a cleaning member 556 and a fixed shaft sleeve 557. The position of the hydraulic rotating member 553 matches the position of the water inlet 552, so that when the water flows into the shell 551 from the water inlet 552, it can push the hydraulic rotating member 553 to rotate. The hydraulic rotating member 553 is connected to the follower 554, and the follower 554 is connected to the swinging member 555. The follower 554 can rotate with the hydraulic rotating member 553, thereby driving the swinging member 555 to swing. The fixed shaft sleeve 557 is fixed in the shell 551. One end of the cleaning member 556 passes through the fixed shaft sleeve 557 and is connected to the swinging member 555, and the other end corresponds to the filter screen of the water outlet 558. The swinging of the swinging member 555 can drive the cleaning member 556 to move, so as to clean the impurities adsorbed on the filter screen and prevent the impurities from clogging the filter screen.

[0108] The hydraulic rotating part 553 includes a wheel 5531, a bearing connecting seat 5532 and a connecting rod 5533. The bearing connecting seat 5532 is fixed in the housing 551. The wheel 5531 is connected to the housing 551 through the bearing connecting seat 5532. One end of the connecting rod 5533 is connected to the wheel 5531, and the other end is connected to the follower 554, so that the follower 554 moves with the wheel 5531.

[0109] Exemplarily, the impeller 5531 is configured as a waterwheel structure, and when water flows into the housing 551 , the impeller 5531 can rotate under the push of the water flow.

[0110] The follower 554 includes a follower wheel 5541, a bearing sleeve 5542 and a transmission rod 5543. The follower wheel 5541 is arranged in the bearing sleeve 5542. The bearing sleeve 5542 is connected to the swing member 555 through the transmission rod 5543. The follower wheel 5541 is non-coaxially connected to the rotating wheel 5531 through a connecting rod 5533, so that when the follower wheel 5541 rotates with the rotating wheel 5531, it can drive the bearing sleeve 5542 to move up and down, thereby driving the swing member 555 to swing through the transmission rod 5543. The cleaning member 556 includes a linkage rod 5561 and a cleaning section 5562. One end of the linkage rod 5561 passes through the fixed shaft sleeve 557 and is connected to the swinging member 555, and the other end is fixedly connected to the cleaning section 5562. The linkage rod 5561 and the transmission rod 5543 are arranged on different axes. The position of the cleaning section 5562 corresponds to the filter. The swinging of the swinging member 555 can drive the linkage rod 5561 to rotate, thereby causing the cleaning section 5562 to rotate around the linkage rod 5561 as the axis to clean the filter.

[0111] Preferably, a scraper or a cleaning brush is provided on the cleaning section 5562 to increase the cleaning effect on the filter.

[0112] By setting up the filter component 55, the water flow entering the first placement chamber 541 and the second placement chamber 542 can be filtered to prevent impurities in the water flow from entering the first placement chamber 541 and the second placement chamber 542 to affect the measurement accuracy of the water level meter and cause inaccurate measurement results; the water flow entering the filter component 55 drives the hydraulic rotating part 553 to rotate, so that the cleaning part 556 swings with the rotation of the hydraulic rotating part 553 to clean the filter screen of the water outlet 558, thereby preventing impurities from clogging the filter screen and affecting the water flow entering the first placement chamber 541 and the second placement chamber 542.
