The tensioning mechanism is used to connect the two ends of the main rope 51 together. The tensioning mechanism includes a basket bolt 53 and a rope shackle 54 connected to the two ends of the basket bolt 53, respectively. The two ends of the main rope 51 are respectively provided with a rope ring 52. The rope shackle 54 constitutes a connecting piece for connecting the rope ring 52 of the main rope 51. The two ends of the main rope 51 are respectively connected to the rope shackles 54 at the two ends of the tensioning mechanism. One end of the main rope 51 and the corresponding end of the tensioning mechanism respectively constitute two ends of the traction rope 50. By twisting the basket bolt 53, the two ends of the main rope 51 can be tightened, and in turn the traction rope 50 is tensioned. This is convenient for adjusting the tensioning force and ensuring reliable installation of the steel wire rope. In other embodiments, the tensioning mechanism can not be provided. The two ends of the main rope 51 are directly connected through a shackle. The steel wire rope has a certain amount of sag, which does not affect the movement of the steel wire rope.

[0034] The rope ring 52 of the main pull rope 51 forms a head end traction connection structure for connecting the head end of the trash barrier, the joint of the head end of the trash barrier is provided with a connection hole, the joint of the head end of the trash barrier is connected at the rope ring 52 through a shackle, the size of the rope ring 52 can meet the connection of the rope shackle 54 of the tensioning mechanism and the shackle of the joint of the head end of the trash barrier, and the head end of the trash barrier is connected with one of the rope rings 52. It should be understood that before the trash barrier is laid, the rope ring 52 is moved to a position close to the river bank by the winch 30 to drive the traction rope 50, so as to facilitate the connection operation of the head end of the trash barrier. The trash barrier is connected by using the existing rope ring 52, which is simple in structure and convenient to connect. In other embodiments, a connecting ring can be separately fixed at other positions of the traction rope, and the connecting ring is used to form a head end traction connection structure for connecting the trash barrier, which can ensure that the traction rope drives the trash barrier to move.

[0035] The pulley assembly 40 includes a mounting frame, the mounting frame includes a fixed part for being fixed with the head end fixed pile 20 and a cantilever part cantilevered based on the fixed part, and the deflection pulley 43 is installed at the end of the cantilever part. The fixed part of the mounting frame is a component clamp 41, and the cantilever part of the mounting frame is a cantilever support. The component clamp 41 is tightly clamped and fixed on the head end fixed pile 20, the cantilever support is cantilevered to the horizontal side of the head end fixed pile 20, one end of the cantilever support is fixed with the component clamp 41, and the other end is provided with a pulley mounting lug 42, and the deflection pulley 43 is rotatably installed on the pulley mounting lug 42. The deflection pulley 43 is installed by using the cantilever part of the mounting frame, the mounting frame has a certain deformation ability, which can reduce the stress generated by the pulley assembly 40 under the pulling of the traction rope 50, and is beneficial to reliable use. The clamp is fixed with the head end fixed pile 20, which is convenient for disassembly and maintenance. In other embodiments, the cantilever support can not be provided, and the pulley mounting lug is directly fixed on the component clamp. In other embodiments, the mounting support can be directly welded and fixed on the head end fixed pile.

[0036] The component clamp 41 is a clamp of the pulley assembly 40, and the component clamp 41 includes two clamping pieces oppositely arranged. The two ends of the clamping pieces are respectively provided with connecting lugs, the two clamping pieces are fixed and connected by the connecting lugs at the ends through bolts and nuts, and are tightly clamped and fixed on the corresponding fixed piles. The cantilever support of the pulley assembly 40 shares the bolts and nuts with the connecting lugs at the ends of the two clamping pieces for fixing, which can simplify the connection structure. In other embodiments, a fixed connection structure for fixing the cantilever support can be separately provided on one side clamping piece of the component clamp.

[0037] The first end fixed pile 20 is provided with a first end connecting structure, which can adopt the same structure as the tail end connecting structure, not shown in the figure. When moving the trash barrier first end from one bank of the river to the other bank, the trash barrier first end can be detached from the traction rope 50 and connected to the first end connecting structure on the first end fixed pile 20. In this way, the first end connecting structure of the first end fixed pile 20 and the tail end connecting structure of the tail end fixed pile 10 are used to respectively fasten the first end and the tail end of the trash barrier to the fixed piles on the two banks of the river, and the fixed piles bear the force, avoiding that the traction rope 50 bears a large tension all the time, which is conducive to improving the use reliability. In other embodiments, if the traction rope 50 can ensure reliable force bearing, the first end connecting structure can also not be provided, and the position of the trash barrier is maintained by the traction rope in cooperation with the winch.

[0038] The rack 33 of the winch 30 is provided with a rack holding hoop 31 for holding the tail end fixed pile 10. The rack holding hoop 31 has the same structure as the assembly holding hoop 41. The rack 33 body is fixedly connected to the rack holding hoop 31 through a connecting plate. The tail end fixed pile 10 is held tightly by the rack holding hoop 31, which is convenient for on-site assembly and fixation. In other embodiments, a fixed seat can be welded on the fixed pile, and the winch is fixed on the fixed seat.

[0039] The part of the winch 30 after removing the rack holding hoop 31 and the connecting plate is the main body part thereof. Figure 3 、 Figure 4 、 Figure 5 The center shaft 36 is fixed on the rack 33 of the winch 30, and the winding drum 32 is rotatably installed on the center shaft 36. Two operation shafts are rotatably installed on the rack 33, which are a slow operation shaft 34 and a fast operation shaft 35. The operation shafts are in transmission connection with the winding drum 32. The traction rope 50 is wound on the winding drum 32. When the operation shafts rotate, the winding drum 32 is driven to rotate to drive the traction rope 50 to move. The operation shafts are provided with operation ends for connecting a screwing tool. The operation ends are exposed to facilitate connection with the screwing tool. The winding and unwinding actions of the winch 30 are driven by the additional screwing tool, which can simplify the structure of the winch 30. The winch 30 itself does not have a motor, which is conducive to long-term placement in an outdoor environment and facilitates manual operation without the need to carry a power source. In other embodiments, the winch can also be configured with a motor. When in use, a mobile power source is carried to drive the motor to work to realize the movement of the traction rope.

[0040] The slow operation shaft 34 and the fast operation shaft 35 are both in transmission connection with the winding drum 32, but the transmission ratios of the two shafts to the winding drum 32 are different. When the winch 30 is operated, the rotating speed of the winding drum 32 is lower than that of the operation shaft. The transmission ratio of the slow operation shaft 34 to the winding drum 32 is greater than that of the fast operation shaft 35 to the winding drum 32. When the slow operation shaft 34 is operated, the moving speed of the traction rope 50 is slow, and when the fast operation shaft 35 is operated, the moving speed of the traction rope 50 is fast. Different operation shafts can be selected according to the needs to facilitate the control of the moving speed of the trash barrier. In other embodiments, only one operation shaft can be provided.

[0041] The transmission structure between the operation shaft and the winding drum 32 includes a worm gear mechanism, and the mechanical locking function of the worm gear mechanism can avoid the reverse movement of the traction rope 50. In other embodiments, a conventional gear transmission structure can also be used according to the needs.

[0042] The slow operation shaft 34 is in transmission connection with the fast operation shaft 35 through a gear set. The worm gear mechanism includes a worm wheel 37 fixedly connected with the winding drum 32 and a worm 38 integrally formed on the fast operation shaft 35. When the fast operation shaft is operated by a screwing tool, the worm gear mechanism is used to reduce the speed and increase the torque. When the slow operation shaft is operated by a screwing tool, the gear set and the worm gear mechanism are used to reduce the speed and increase the torque. The screwing tool can be an electric wrench or a manual wrench.

[0043] The fixed pile is a steel pipe with a length of 3 m, and the buried depth is not less than 1.8 m. The steel pipe is filled with cement mortar. The steel wire rope part of the traction rope 50 is a steel wire rope with a diameter of Φ8 mm. The winch 30 is a friction type winch. In this embodiment, the trash barrier is an oil containment boom.

[0044] The use of the trash barrier arrangement will be described below in combination with the layout process of the oil containment boom.

[0045] After the oil containment boom is transported to the site, each section of the oil containment boom is unfolded and placed on the road in sequence to ensure that there is no obstacle to enter the water. Each section of the oil containment boom is provided with a thickened joint with holes at both ends. When connected, the joints of the adjacent two sections are overlapped and assembled together by connecting bolts and the through holes in the joints.

[0046] The first section of the oil containment boom is connected with the towing rope 50 by a U-shaped shackle at the end of the oil containment boom, and the last section of the oil containment boom is fixedly connected with the steel wire rope on the tail end fixing post 10 on the tail end of the oil containment boom on the left bank wave protection wall by a U-shaped shackle. After the oil containment boom is connected, the winch 30 is driven by a rotating tool, and the oil containment boom is slowly dragged into the water by the towing rope 50. Before being put into the water, the skirt body of the oil containment boom is arranged to avoid twisting and entanglement of the oil containment boom after being put into the water, and to ensure smooth deployment. In order to prevent damage to the oil containment boom, a mat or a sliding rack is laid at the water inlet of the oil containment boom to prevent sharp objects from damaging the oil containment boom. The oil containment boom is dragged by an operator holding an electric tool to drive the winch 30, and when the load is small, the fast operation shaft 35 can be used for traction, and when the load is large, the slow operation shaft 34 is switched.

[0047] When the oil containment boom approaches the opposite bank of the river, the operator detaches the oil containment boom from the towing rope 50 and connects it to the first end fixing post 20 on the right bank of the river through the steel wire rope and the shackle, thereby completing the anchor point switching of the oil containment boom. The recovery steps of the oil containment boom are opposite to the deployment steps.

[0048] The deployment device uses a portable handheld electric tool to drive the winch instead of manual dragging, so that 5 people can complete the rapid deployment of the oil containment boom within 30 minutes, greatly reducing the labor input, improving the deployment efficiency, and ensuring that the emergency event can be responded quickly. The deployment device basically does not involve dangerous operation during operation, and the risk of mechanical injury is low when the electric tool is used to drive the winch, which can reduce the risk of illegal operation of personnel and improve the safety performance of the equipment. The deployment device can be deployed multiple times, has high work efficiency, requires less resource input, runs stably and reliably, and has low equipment maintenance cost.

[0049] Finally, it should be noted that the above-described preferred embodiments of the present application are not intended to limit the present application, and although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments without creative labor, or make equivalent substitutions for some technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
