Abstract

This invention relates to the field of water conservancy engineering technology, specifically to a debris-blocking and buffering system. It includes a pontoon frame, within which multiple pontoons are mounted and float up and down along guide rails. The pontoon frame contains a pontoon-limiting assembly that generates an inwardly converging rebound force to restrict the pontoons. A slot is formed on the upstream side of the pontoon frame, within which a buffering and resisting assembly is installed. One end of the buffering and resisting assembly is elastically and movably connected to the outer wall of the pontoon frame near the bottom, and the other end is elastically and movably connected to a limiting pressure member, the end of which abuts against the pontoon-limiting assembly. This invention allows the buffering and resisting assembly to switch from an "I" shape to a "V" shape, dispersing the impact force, thereby reducing stress concentration and minimizing impact damage. Simultaneously, the rebound force generated by the switching of the buffering and resisting assembly can buffer rigid impacts, slowing the rate of damage and deformation of the pontoon frame and increasing its service life.

Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and more specifically, to a sewage interception and buffer system with sewage guiding and buffering functions. Background Technology

[0002] A debris barrier is a facility used to intercept pollutants. It's a physical barrier installed in a body of water to block floating debris and garbage. Simply put, it acts like a "net," trapping floating trash, branches, oil, and other contaminants from polluting the water.

[0003] The current debris barrier system consists of two floating structures with pontoons inside, which float on the water surface. The two floating structures are connected by a string of pontoons, and the outer walls of the pontoons are equipped with debris barriers. As the pontoons float on the water surface, the debris barriers are submerged in the water to intercept various floating objects, preventing water pollution. Furthermore, as the string of pontoons prevents the movement of floating objects, it can guide the floating objects, which is beneficial for subsequent sewage discharge and pollution guidance.

[0004] However, the current floating box structure has limited strength. Upstream power stations accumulate a large amount of weeds and driftwood. During the flood season, when the power station discharges driftwood, a large amount of driftwood is discharged, causing the floating box structure to be subjected to strong impact damage. The outer wall of the floating box structure is mostly a planar structure, which not only cannot buffer the impact force, but is also very easy to deform upon impact. This results in a large opening on the outer wall of the floating box, causing the floats inside the floating box to be lost, which affects the effectiveness of supporting the float strings in intercepting foreign objects and guiding pollution.

[0005] Furthermore, the high-strength closed spiral buckles connecting the float strings are prone to unscrewing due to impact, causing the float connections to break and affecting the effectiveness of intercepting foreign objects and guiding pollution. Therefore, we propose a pollution interceptor with a pollution guiding and buffering function. Summary of the Invention

[0006] The purpose of this invention is to provide a wastewater interceptor with a wastewater guiding and buffering function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides a debris barrier with a debris-guiding and buffering function, comprising a float frame, wherein multiple pontoons are mounted inside the float frame and float up and down along guide rails; the float frame is provided with a pontoon limiting component for generating an inwardly converging rebound force to limit the pontoons; a slot is provided on the upstream side of the float frame, and a buffer resisting component is provided in the slot; one end of the buffer resisting component is elastically movably connected to the outer wall of the float frame near the bottom, and the other end is elastically movably connected to a limiting pressing component; the end of the limiting pressing component abuts against the pontoon limiting component, wherein:

[0008] The buffer component elastically absorbs the impact force on the pontoon frame, changing from an "I" shape to a "V" shape to fit the pontoon, and drives the limiting pressing component to move downward, again limiting and pressing against the top of the pontoon limiting component.

[0009] As a further improvement to this technical solution, the buffer and resisting component includes at least two grid baffles, and an elastic movable member is provided between the two grid baffles for driving the two grid baffles to rotate elastically. Elastic movable members are also provided between the ends of the two grid baffles and the bottom and top of the slotted inner cavity, respectively.

[0010] As a further improvement to this technical solution, the elastic movable component includes a rotating sleeve, the inner wall of which has a cavity, a spiral rod rotatably disposed inside the cavity, and a threaded spring sleeved on the outer wall of the spiral rod. One end of the spiral spring is fixedly connected to the end of the cavity, and the other end is fixedly connected to the outer wall of the spiral rod. The end of the spiral rod and the end of the rotating sleeve are respectively connected to the ends of the two grid baffles, the slotted inner cavity, and one of the grid baffle ends.

[0011] As a further improvement to this technical solution, a groove is provided on the top of the pontoon frame, and the pontoon limiting assembly includes a pressure plate that slides inside the groove. An elastic element is fixedly connected between the pressure plate and the pontoon frame, and the elastic element is used to limit the pontoon between the pressure plate and the bottom of the pontoon frame's inner cavity when it is in a stretched state.

[0012] As a further improvement to this technical solution, a limiting groove is provided at the top edge of the floating box frame, and a limiting slide is provided between the rotating sleeve ends at the top of the grooved inner cavity. The limiting slide slides inside the limiting groove, and the end of the limiting pressing member is fixedly connected to the top of the limiting slide.

[0013] As a further improvement to this technical solution, the limiting pressing component and the floating box frame are in the shape of a "triangular" support.

[0014] As a further improvement to this technical solution, the pontoon frame is provided in two symmetrical configurations, with multiple pontoon components between the two pontoon frames. A connecting cable runs through the multiple pontoon components, and the multiple pontoon components are connected together by marine polymer cables to form a pontoon string. The two ends of the connecting cable are respectively connected and fixed to the top of the two pontoon frames.

[0015] As a further improvement to this technical solution, a filter plate is fitted on the outer wall of the float component, and multiple holes for water flow are opened on the surface of the filter plate, and multiple counterweights are fixedly connected to the end of the filter plate away from the float component.

[0016] As a further improvement to this technical solution, the two ends of the connecting cable are detachably connected to the two float frames by means of locking buckles.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In this debris-blocking and buffering system, when the pontoon frame is impacted by upstream foreign objects or water flow, the impact force acts directly on the surface of the buffering and resisting components, causing the buffering and resisting components to switch from an "I" shape to a "V" shape. The "V" shape has a larger surface area than the "I" shape, which can disperse the impact force, thereby reducing stress concentration and minimizing impact damage. At the same time, the rebound force generated by the switching of the buffering and resisting components can buffer the rigid impact, reduce the rate of damage and deformation of the pontoon frame, and improve its service life.

[0019] 2. In this debris barrier with a pollution guiding and buffering function, the elastic force of the float limiting component can gather and clamp the float in the limiting float frame body. When subjected to impact, during the switching state of the buffer resisting component, the limiting pressing component moves downward to abut against the float limiting component, which helps to improve the strength of the float limiting component in restricting the float. At the same time, the "V"-shaped buffer resisting component can also squeeze the float to prevent the float from detaching from the float frame body and causing the float to be lost.

[0020] 3. In this debris-blocking and buffering system, when the impact force stops, the buffering and resisting components reset to the "I" position, which can prevent the floats inside the float box frame from being damaged by prolonged compression. The floats are only compressed at the moment of impact. When there is no impact, the floats continue to be in an expanded state, driving the float string to intercept foreign objects and guiding the foreign objects as the float string moves, which is beneficial to the subsequent sewage discharge effect.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] A debris barrier is a facility used to intercept pollutants. It's a physical barrier installed in a body of water to block floating debris and garbage. Simply put, it acts like a net, trapping floating trash, branches, oil, and other contaminants to prevent them from polluting the water. (See also: [link to relevant documentation]). Figures 1-7 As shown, this embodiment provides a debris barrier with a debris-guiding and buffering function, including a float frame 100. Multiple floats are mounted inside the float frame 100 and float up and down along guide rails. The float frame 100 has a float limiting component 400 inside, which generates an inwardly converging rebound force to limit the floats. A slot is opened on the upstream side of the float frame 100, and a buffer resisting component 200 is provided in the slot. One end of the buffer resisting component 200 is elastically and movably connected to the outer wall of the float frame 100 near the bottom, and the other end is elastically and movably connected to a limiting pressing member 300. The end of the limiting pressing member 300 abuts against the float limiting component 400. Wherein:

[0036] The buffer component 200 elastically absorbs the impact force on the float frame 100, changing from an "I" shape to a "V" shape to fit the float, and drives the limiting pressing component 300 to move downward, again limiting and pressing against the top of the float limiting component 400.

[0037] This invention addresses the issue that current pontoon structures have planar surfaces, which not only fail to buffer impact forces but are also highly susceptible to deformation. This results in large openings in the outer wall of the pontoon, potentially causing the loss of internal pontoons and affecting the effectiveness of the pontoon string in intercepting foreign objects. Therefore, as... Figure 2 and Figure 6 As shown, when the pontoon frame 100 is impacted by upstream foreign objects or water flow, the impact force is directly applied to the surface of the buffer and resist component 200, causing the buffer and resist component 200 to switch from an "I" shape to a "V" shape. The "V" shape has a larger surface area than the "I" shape, which can disperse the impact force, thereby reducing stress concentration and minimizing impact damage. At the same time, the rebound force generated by the switching of the buffer and resist component 200 can buffer the rigid impact, reduce the rate of damage and deformation of the pontoon frame 100, and improve its service life.

[0038] Furthermore, the elastic force of the float restraint component 400 can inwardly gather and clamp the float inside the limit float frame 100. When subjected to impact, during the switching state of the buffer resist component 200, the limit pressing component 300 moves downward to press against the float restraint component 400, which helps to improve the strength of the float restraint component 400 in restricting the float. At the same time, the "V"-shaped buffer resist component 200 can also squeeze the float to prevent the float from detaching from the float frame 100 and causing the float to be lost.

[0039] When the impact force stops, the buffer component 200 resets to the "I" position, which can prevent the floats inside the float box frame 100 from being damaged by prolonged compression. The floats are only compressed at the moment of impact. When there is no impact, the floats continue to be in an expanded state, driving the float string to intercept foreign objects and ensuring structural integrity.

[0040] Based on the above, the specific structure needs to be disclosed:

[0041] First, to ensure that the buffer resisting component 200 can absorb impact forces, the structure of the buffer resisting component 200 is further disclosed; please refer to [link to relevant documentation]. Figure 5 As shown, the buffer and resisting assembly 200 includes at least two grid baffles 210. An elastic movable member 220 is provided between the two grid baffles 210 for driving the two grid baffles 210 to rotate elastically. Elastic movable members 220 are also provided between the ends of the two grid baffles 210 and the bottom and top of the slotted inner cavity, respectively.

[0042] Specifically, the elastic movable component 220 includes a rotating sleeve 221, with a cavity 223 formed in the inner wall of the rotating sleeve 221. A helical rod 222 is rotatably mounted inside the cavity 223. A threaded spring is fitted onto the outer wall of the helical rod 222. One end of the helical spring is fixedly connected to the end of the cavity 223, and the other end is fixedly connected to the outer wall of the helical rod 222. The end of the helical rod 222 and the end of the rotating sleeve 221 are respectively connected to the ends of two grid baffles 210, the slotted inner cavity, and the end of one of the grid baffles 210. When the grid baffle 210 is subjected to an impact force, the spiral rod 222 rotates inside the cavity 223, causing the spiral spring to twist. This generates a rotational rebound force between the two grid baffles 210 and between the grid baffle 210 and the slot. The rebound force can buffer the impact and allow the grid baffle 210 to switch to a "V" shape. Conversely, when the impact force stops, the rebound force of the spiral spring causes the two grid baffles 210 to return to their original position and cover the slot, preventing the float frame 100 from deforming and being damaged.

[0043] Furthermore, to enable the float restraint assembly 400 to generate an inwardly converging force to prevent the float from detaching from the float box frame 100, please refer to [link to relevant documentation]. Figure 3 As shown, the results of the float limiting assembly 400 are further disclosed. A groove 120 is provided on the top of the float frame 100. The float limiting assembly 400 includes a pressure plate 410 that slides inside the groove 120. An elastic member 420 is fixedly connected between the pressure plate 410 and the float frame 100. The elastic member 420 is used to limit the float between the pressure plate 410 and the bottom of the inner cavity of the float frame 100 when it is in a stretched state.

[0044] As for the pontoon frame 100, it can be spliced ​​from multiple angle steels to form a frame structure, and the top and bottom of the pontoon frame 100 are covered by upper and lower steel plates, and only the steel plate at the top of the pontoon frame 100 forms a groove 120 for the pressure plate 410 to move up and down.

[0045] Next, when the buffer and resist component 200 is subjected to impact force, the limiting pressing component 300 moves downward to abut against the pressure plate 410, increasing the strength of the pressure plate 410 in restricting the pontoon. A limiting groove 110 is opened at the top edge of the pontoon frame 100. A limiting slide plate 310 is provided between the ends of the rotating sleeve 221 at the top of the groove. The limiting slide plate 310 slides inside the limiting groove 110, and the end of the limiting pressing component 300 is fixedly connected to the top of the limiting slide plate 310. The limiting groove 110 not only restricts the movement of the upper grid baffle 210 in the vertical direction to prevent the grid baffle 210 from falling out of the groove, but also drives the limiting slide plate 310 to move downward to abut against the pressure plate 410 and press it down again, further restricting the pontoon.

[0046] Specifically, the limiting pressing component 300 and the float frame 100 are in the shape of a "triangular" support. Even if the limiting pressing component 300 is impacted, the "triangular" support structure can provide greater bending resistance, thereby better resisting bending deformation caused by impact.

[0047] Then, to achieve the ability to intercept and guide garbage in the water, such as... Figure 1 and Figure 6 As shown, there are two symmetrical pontoon frames 100, and multiple pontoon components 500 are provided between the two pontoon frames 100. A connecting cable 510 runs through the multiple pontoon components 500. The multiple pontoon components 500 are connected together by marine polymer cables through the connecting cable 510 to form a pontoon string. The two ends of the connecting cable 510 are respectively connected and fixed to the top of the two pontoon frames 100. The two pontoon frames 100 are installed on the top of the trash rack pier and move longitudinally along the guide structure, so that the pontoon frames 100 float on the water surface with the buoyancy of the pontoons. This pulls the pontoon string formed by the multiple connecting cables 510. Furthermore, the marine polymer cables of the connecting cables 510 are usually made of high-strength synthetic fibers, such as nylon, polyester, Kevlar, etc., which have high tensile strength and wear resistance, and can withstand large tensile forces and friction forces, reducing the breakage between the pontoon strings and the loss of the pontoons of the pontoon components 500.

[0048] Among them, marine polymer cables are used instead of high-strength closed spiral buckles, and 15 additional pontoon components 500 are manufactured, including 2 steel pontoons, which are installed at the contact position of the trash rack piers to achieve a smaller spacing between the pontoon components 500, thereby improving the subsequent trash interception and guidance effect. In addition, the two steel pontoons at both ends are made of LLDPE pontoons: which are widely used, have high buoyancy, small size, light weight, and are easy to replace. Furthermore, steel pontoons are sturdy, have strong impact resistance, and are heavy and large in size.

[0049] Specifically, in order to improve the sewage guiding effect of the multiple pontoon components 500 and prevent excessive garbage accumulation that would cause the garbage below to float past the bottom of the pontoon components 500, such as... Figure 6 As shown, a filter plate 520 is fitted onto the outer wall of the float 500. The surface of the filter plate 520 has multiple holes for water flow. Multiple counterweights 521 are fixedly connected to the end of the filter plate 520 away from the float 500. The weight of the counterweights 521 pulls the lower end of the filter plate 520 into the water, and the float 500 drives the filter plate 520 to float in the water. This allows the float 500 to intercept floating garbage on the water surface. When a large amount of garbage accumulates, the garbage submerged in the water is intercepted by the filter plate 520, improving the garbage interception effect.

[0050] The two ends of the connecting cable 510 are detachably connected to the two pontoon frames 100 via latches. When it is necessary to discharge or guide the waste, the connecting cable 510 is released from the latches, so that the ends of the connecting cable 510 are detached from the pontoon frame 100. With the help of other equipment (boat, pulling rod, etc.), the ends of the two connecting cables 510 are pulled to move, so that the waste is pushed by the pontoon component 500 and guided to the required location for discharge.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
