Description

Technical Field

[0001] This utility model relates to the field of float barriers, and more particularly to a float barrier device that can be lifted out of the water. Background Technology

[0002] Conventional drift barriers are primarily designed to intercept floating objects in low-velocity conditions and then salvage them ashore. However, when the current velocity in the drift-blocking area exceeds 3.0 m / s, the drift barriers become ineffective, and since they cannot be dismantled, the tension on the barriers far exceeds the design value for normal flow velocities. This can damage the drift-blocking boxes or even the anchoring piers. To avoid this, the barriers need to be dismantled in advance to protect the entire drift-blocking system; otherwise, significant economic losses may occur. When drift barriers operate in northern waters that freeze in winter, manual dismantling is necessary before winter arrives. However, manual dismantling is very difficult, poses high safety risks to personnel, and restoration is time-consuming, labor-intensive, and extremely costly.

[0003] In the existing technology of drift barriers, Chinese invention patent: an automatic control system and method for drift barriers, publication number: CN118128004A, discloses that by installing a tension sensor and a water level sensor on the drift barrier unit, and connecting a lifting winch and a tensioning winch to both ends of the drift barrier unit, the lifting winch lifts the drift barrier unit after the water level sensor detects that the water level exceeds the set value, ensuring that the drift barrier unit is always on the water surface.

[0004] The above document has the following problems:

[0005] 1. The technical solution described in the aforementioned comparative document is to adjust the height of the drift barrier by raising or lowering it using a lifting winch and a tensioning winch, based on changes in water level. This ensures that the drift barrier unit is always on the water surface. During the adjustment process, some floats are always on the water surface to provide buoyancy support for the drift barrier. Therefore, it is not intended to lift the entire drift barrier out of the water.

[0006] 2. If the technical solution described in the aforementioned comparative document is used to lift the entire drift barrier out of the water, without the support of buoyancy from the water surface, the main traction cable of the drift barrier will be subjected to excessive tension during the lifting process from both ends, which may cause the main traction cable to break. If the main traction cable breaks, the drift barrier box will also be damaged. Furthermore, since the lifting winch is located on the anchor pier, when the anchor pier is subjected to the huge tension brought by the main traction cable, it may cause the anchor pier to be pulled over, resulting in damage to the entire drift barrier device and a major safety accident. Summary of the Invention

[0007] The purpose of this invention is to overcome the above-mentioned problems of the prior art and to propose a float-blocking device that can be lifted out of the water, thus solving the problem that the float-blocking device cannot be lifted out of the water as a whole when the current speed in the float-blocking area exceeds the limit or the water is frozen and there is no buoyancy to support it.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A float-blocking device that can be lifted out of the water is characterized in that it includes a float-blocking end lifting mechanism and a float-blocking middle lifting mechanism. The float-blocking end lifting mechanism is used to drive the float-blocking to move upward or downward from both ends of the float-blocking, and the float-blocking middle lifting mechanism is used to drive the float-blocking to move upward or downward from the middle of the float-blocking. The float-blocking end lifting mechanism and the float-blocking middle lifting mechanism work together to lift the entire float-blocking to the water surface.

[0010] The drift barrier end lifting mechanism consists of two parts, which are respectively installed on the first anchoring pier and the second anchoring pier.

[0011] Both the first anchoring pier and the second anchoring pier are equipped with sliding limiting mechanisms; both the first anchoring pier and the second anchoring pier are equipped with ground anchor devices on their outer sides; one end of the main cable steel wire rope of the cross-pier is connected to the ground anchor device on the outer side of the first anchoring pier, and the other end of the main cable steel wire rope of the cross-pier passes through the sliding limiting mechanisms on the first anchoring pier and the second anchoring pier in sequence before connecting to the ground anchor device on the outer side of the second anchoring pier.

[0012] The drift barrier includes a drift box, a grate, and a drift barrier traction cable. The two ends of the drift barrier traction cable are respectively set on the lifting mechanisms at the ends of the two drift barriers. The drift box and the grate form a drift barrier on the drift barrier traction cable.

[0013] The middle lifting mechanism of the drift barrier includes two drift barrier lifting devices and a remote steel wire rope. The two drift barrier lifting devices are set on the first anchoring pier and the second anchoring pier. One end of the remote steel wire rope is connected to the drift barrier lifting device, and the other end of the remote steel wire rope passes through the guide device on the main cable of the cross-pier and is connected to the suspension point on the main traction cable of the drift barrier.

[0014] The end lifting mechanism of the drift barrier includes a lifting device, a sliding track, and an end trolley. The sliding track is set on the anchor pier, the lifting device is fixedly set on the top of the sliding track, and the end trolley is set on the sliding track. The lifting device is connected to the end trolley, the drift barrier traction main cable is connected to the end trolley, and the end trolley is lifted by the lifting device to drive the end of the drift barrier traction main cable to be lifted.

[0015] The sliding limiting mechanism is a slide groove or a pulley.

[0016] The guiding device is a guide pulley.

[0017] The main traction cable of the drift barrier has at least one suspension point.

[0018] The advantages of using this utility model are:

[0019] I. Compared with the prior art, the present invention can quickly lift the entire float out of the water by means of the lifting mechanism at the end of the float and the lifting mechanism in the middle of the float, thus preventing the float box from being damaged by high-speed impacts from floating objects.

[0020] II. When it is necessary to lift the drift barrier out of the water, the drift barrier traction main cable is connected to the main cable of the drift barrier through the central lifting device passing through the main cable of the cross pier. At this time, the main cable of the cross pier slides slightly in the groove or pulley at the top of the anchoring pier after being under tension, automatically adjusting the tension at both ends to a balanced state. The anchoring pier mainly bears the vertical downward pressure or very small radial tension of the main cable of the cross pier, and there is no risk of overturning due to excessive tension. The tension on the main cable of the cross pier is transferred to the ground anchor device, thereby ensuring the safety of the drift barrier system.

[0021] Third, this utility model sets up a main cable steel wire rope across the pier, which can lift the main cable of the drift barrier out of the water in multiple sections, thereby reducing the suspension catenary sag of each section, reducing the height of the anchor pier, lowering the center of gravity of the anchor pier, and significantly reducing the risk of the anchor pier overturning.

[0022] Fourth, the main cable of the cross-pier is equipped with guide pulleys, which can quickly and efficiently lift the buoy out of the water and is easy to operate.

[0023] Fifth, for operating conditions where the flow rate changes frequently or the flow rate is frequently adjusted, this utility model can quickly switch between the drift interception function and the drift interception and discharge function to the water surface according to the changes in operating conditions, thereby protecting the drift interception system.

[0024] VI. When the watershed is frozen, this utility model does not require the removal of the floatation barrier. The floatation box and accessories are simply lifted out of the water and lowered back down to restore the floatation barrier function after the watershed thaws, which greatly saves costs.

Detailed Implementation

[0031] Example 1

[0032] A float-blocking device that can be lifted out of the water includes a float-blocking end lifting mechanism 3 and a float-blocking middle lifting mechanism 4. The float-blocking end lifting mechanism 3 is used to drive the float-blocking 1 to move upward or downward from both ends of the float-blocking 1, and the float-blocking middle lifting mechanism 4 is used to drive the float-blocking 1 to move upward or downward from the middle of the float-blocking 1. The float-blocking end lifting mechanism 3 and the float-blocking middle lifting mechanism 4 work together to lift the float-blocking 1 out of the water as a whole.

[0033] There are two lifting mechanisms 3 at the end of the drift barrier, which are respectively installed on the first anchor 5 and the second anchor 6.

[0034] Both the first anchoring pier 5 and the second anchoring pier 6 are equipped with sliding limiting mechanisms 7; both the first anchoring pier 5 and the second anchoring pier 6 are equipped with ground anchor devices 12 on their outer sides; one end of the main cable steel wire rope 11 is connected to the ground anchor device 12 on the outer side of the first anchoring pier 5, and the other end of the main cable steel wire rope 11 passes through the sliding limiting mechanisms 7 on the first anchoring pier 5 and the second anchoring pier 6 in sequence before connecting to the ground anchor device 12 on the outer side of the second anchoring pier 6.

[0035] The drift barrier 1 includes a drift barrier box 17, a hanging grid 18, and a drift barrier traction main cable 2. The two ends of the drift barrier traction main cable 2 are respectively set on the two drift barrier end lifting mechanisms 3. The drift barrier box 17 and the hanging grid 18 form the drift barrier 1 on the drift barrier traction main cable 2.

[0036] The middle lifting mechanism 4 of the drift barrier includes two drift barrier lifting devices 8 and a remote steel wire rope 9. The two drift barrier lifting devices 8 are set on the first anchoring pier 5 and the second anchoring pier 6. One end of the remote steel wire rope 9 is connected to the drift barrier lifting device 8, and the other end of the remote steel wire rope 9 passes through the guide device on the main cable steel wire rope 11 of the cross pier and is connected to the suspension point 10 on the drift barrier traction main cable 2.

[0037] The end lifting mechanism 3 of the drift barrier includes a lifting device, a sliding track 15, and an end trolley 16. The sliding track 15 is set on the anchor pier, the lifting device is fixedly set on the top of the sliding track 15, and the end trolley 16 is set on the sliding track 15. The lifting device is connected to the end trolley 16, and the drift barrier traction main cable 2 is connected to the end trolley 16. The end trolley 16 is lifted by the lifting device, which drives the end of the drift barrier traction main cable 2 to be lifted.

[0038] The sliding limiting mechanism 7 is a groove or a pulley.

[0039] The guiding device is a guide pulley 13.

[0040] The main traction cable 2 of the drift barrier has at least one suspension point 10.

[0041] like Figure 1-5 As shown, when it is necessary to lift the drift barrier 1 out of the water, the lifting device 14 lifts the end pulley 16 to rise, thereby lifting the end of the drift barrier traction main cable 2. The drift barrier box 17 and the hanging grid 18 or hanging net installed on the drift barrier traction main cable 2 also rise accordingly until they are completely out of the water. This must be coordinated with the drift barrier middle lifting mechanism 4. Guide pulleys 13 are installed at corresponding positions on the main cable 11 of the cross-pier above the lifting position of the drift barrier traction main cable 2 to guide the remote steel wire rope 9 of the drift barrier 1 middle lifting device. Lifting points 10 are set at one, two or more suitable positions on the drift barrier traction main cable 2, and the drift barrier lifting device 8 of the drift barrier middle lifting mechanism 4 tightens the remote steel wire rope 9 to lift the remote steel wire rope 9 of the drift barrier traction main cable 2 middle lifting device of the drift barrier 1. The drift barrier box 17, the hanging grid 18 or hanging net can be lifted out of the water from one, two or more positions at the same time.

[0042] The lifting devices in the end lifting mechanism 3 and the middle lifting mechanism 4 of the drift barrier can be operated in conjunction or independently, depending on the needs of the on-site operation, until all drift barriers 17 and hanging grids 18 are lifted out of the water.

[0043] This invention is highly suitable for operating conditions where flow velocity changes frequently or flow rates are often adjusted (such as flood discharge and sediment flushing) and for watersheds that may freeze in winter. Traditionally, before the watershed freezes, the floating box 1 and related components of the floating barrier 1 need to be completely removed to protect the floating box 17 from damage caused by the enormous squeezing force generated by freezing. The process of removing the floating box and restoring the floating barrier 1 is very time-consuming, labor-intensive, costly, and involves a huge amount of work with high safety risks. In these operating conditions, it is necessary to switch between raising the floating box 17 to the surface and lowering it for flood control at any time. This invention uses the lifting mechanism 3 at the end of the floating barrier 1 and the lifting mechanism 4 in the middle of the floating barrier 1 to safely and quickly raise the floating barrier 1 to the surface, making it very suitable for the above-mentioned operating conditions.

[0044] In order to reduce the tension of the main cable 11 across the pier and the main traction cable 2 of the drift arrester, the present invention allows for multiple anchoring piers. Pulleys or grooves are installed on the anchoring piers, allowing the main cable 11 across the pier to slide slightly on the grooves or pulleys at the top of the anchoring pier, automatically adjusting the tension at both ends to a balanced state. This ensures that the anchoring piers primarily bear the downward vertical pressure or very small radial tension of the main cable 11 across the pier, eliminating the risk of overturning due to excessive tension. The tension on the main cable 11 across the pier is then transferred to the ground anchor device 12. The number of other components can be increased accordingly to match this.

[0045] In order to reduce the tension of the relevant steel wire ropes in the entire float-blocking system, it is necessary to reduce the weight of the individual float-blocking box 17. The float-blocking box 17 should preferably be made of high-strength non-metallic materials (such as polyethylene PE plastic) or lightweight metal materials (such as aluminum alloy).
