Description

Technical Field

[0001] The present application relates to the technical field of water channel debris cleaning equipment, and in particular to a pollution intercepting device for an open channel. Background Art

[0002] As an important water flow channel, open channels carry the key task of water transportation and discharge. However, as water flows in the open channel, various types of dirt such as branches, plastic bags, domestic garbage and other strips and blocks of debris often enter. If these dirt are not cleaned up in time, it will not only cause blockage of the open channel and affect the smooth flow of water, but these debris may also flow into the downstream water body and even pose a threat to downstream water treatment equipment, pumping stations and other infrastructure, resulting in equipment damage and increased operating costs.

[0003] Traditional open channel cleaning methods mostly rely on manual salvage or regular shutdown cleaning. Traditional cleaning methods are not only inefficient and labor-intensive, but also difficult to be timely and effective. Especially when the water level fluctuates greatly, the difficulty and cost of cleaning are significantly increased, and frequent maintenance operations also increase the consumption of manpower and material resources.

[0004] Based on the above problems, there is an urgent need for a pollution-blocking device that can automatically intercept debris on the open channel and facilitate cleaning. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a pollution interception device for an open channel, which can intercept debris in the water to reduce the pollution of the environment by the debris.

[0006] The present application provides a pollution interception device for an open channel, comprising:

[0007] A fixed frame and at least two movable pollution-blocking frames; both sides of the fixed frame are connected to the channel wall of the open channel through connecting parts, the connecting ends of at least two movable pollution-blocking frames are movably connected to the fixed frame in turn, the intercepting ends of at least two movable pollution-blocking frames are downwardly suspended into the water of the open channel, the intercepting ends are controlled to rotate around the connecting ends, a height difference is set between adjacent intercepting ends, and the movable pollution-blocking frames intercept debris in the water through the intercepting ends.

[0008] Optionally, the connecting member is a bolt or an expansion screw, and transverse through holes are provided on both sides of the fixing frame, and the bolt or the expansion screw passes through the through holes to be connected to the channel wall.

[0009] Optionally, the connecting member is a fixing column, the fixing column is fixed on both sides of the fixing frame, the channel wall is provided with a step, the fixing frame is clamped on the step through the fixing column, and the step is used to adjust the height of the fixing column.

[0010] Optionally, the movable frame is composed of an intercepting rod, a connecting rod and side rods. The intercepting rod is arranged parallel to the connecting rod. Both ends of the intercepting rod are connected to both ends of the connecting rod through the side rods. The connecting rod is used for movably connecting with the fixed frame, and the intercepting rod is used for intercepting sundries in the water.

[0011] Optionally, a plurality of raised blocks are arranged on the surface of the intercepting rod.

[0012] Optionally, a groove is arranged on the fixed frame. The groove is used for accommodating the connecting rod, and the connecting rod is controlled to rotate in the groove.

[0013] Optionally, limiting plates are respectively arranged at both ends of the connecting rod. The diameter of the limiting plate is larger than that of the connecting rod. The limiting plate is used for restricting the connecting rod from moving back and forth on the fixed frame.

[0014] Optionally, both the fixed frame and the anti-pollution movable frame are made of stainless steel, fiberglass or polyethylene.

[0015] Optionally, 4 anti-pollution movable frames are arranged on the fixed frame. Each anti-pollution movable frame is detachably connected to the fixed frame.

[0017] In the present application, a fixed frame is arranged in the open channel, and at least 2 anti-pollution movable frames are movably connected to the fixed frame. The connecting ends of the anti-pollution movable frames are connected to the fixed frame, and the intercepting ends hang down into the water. When there are sundries in the water, the sundries are wound around the intercepting ends, so as to realize the automatic interception and collection of the sundries. With the impact of the water flow, the intercepting ends of the anti-pollution movable frames swing in the water, which is convenient for intercepting more sundries. When a certain number of sundries are intercepted, the anti-pollution movable frames are lifted manually to clean the sundries on the intercepting ends. Therefore, through the present application, the effect of automatically intercepting sundries in the open channel can be achieved, the number of sundries in the water can be reduced, and thus the degree of environmental pollution caused by the sundries can be reduced.

Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0030] To efficiently and flexibly intercept various types of debris in the water flowing through an open channel, such as floating objects, suspended solids, and some sediments, to ensure water quality safety and the normal operation of subsequent treatment equipment, this application provides a trash interception device for an open channel, which is used to intercept debris in the water to reduce environmental pollution caused by the debris. The specific implementation process of this application is described as follows.

[0031] Please refer to Figures 1 to 5 , a trash interception device for an open channel provided by this application includes:

[0032] A fixed frame 01 and at least two trash interception movable frames 02; both sides of the fixed frame 01 are connected to the channel wall 03 of the open channel through connectors, and the connection ends of at least two trash interception movable frames 02 are sequentially and movably connected to the fixed frame 01. The interception ends of at least two trash interception movable frames 02 hang down into the water of the open channel, and the interception ends are controlled to rotate around the connection ends. There is a height difference between adjacent interception ends, and the trash interception movable frames 02 intercept debris in the water through the interception ends.

[0033] The fixed frame 01 is usually made of high-strength materials (such as stainless steel, galvanized steel, or corrosion-resistant alloy) to ensure stability and durability for long-term use. In an implementable manner, both sides of the fixed frame 01 are firmly connected to the channel wall 03 of the open channel through connectors (such as expansion bolts, anchors, or welding methods) to ensure that the entire device will not shift or topple under the impact of water flow. The width of the fixed frame 01 matches the width of the open channel to ensure the maximum interception efficiency for debris in the open channel water.

[0034] At least two movable trash racks 02 are provided, and the number can be increased according to actual needs to enhance the interception effect. Each movable trash rack 02 is designed to be able to rotate flexibly around its connection point (i.e., the connection end) with the fixed rack 01 to adapt to different water flow conditions, different water levels, and different types of debris. The movable trash rack 02 is also made of corrosion-resistant materials, with a light but strong structure to withstand the impact of water flow and the weight of debris.

[0035] The interception end of the movable trash rack 02 hangs downward into the water of the open channel. The function of the interception end is to effectively intercept debris in the water. The interception end can be equipped with sharp or serrated edges to enhance the ability to capture debris. At the same time, there is a certain height difference between the interception ends of two adjacent movable trash racks 02, which helps to guide the water flow and disperse the debris, improving the interception efficiency.

[0036] The working principle of this application is as follows: When the water flow carries debris through this application, the debris is first captured and intercepted by the interception end of the movable trash rack 02. As the debris accumulates, when it reaches a certain level, the movable trash rack 02 is manually lifted upward, so as to manually clean the debris at the interception end, and then reinstalled into the fixed rack 01 to continue intercepting the debris.

[0037] In an alternative embodiment, the connecting piece is a bolt or an expansion screw. Through holes penetrating horizontally are provided on both sides of the fixed rack 01, and the bolt or expansion screw passes through the through hole to connect with the channel wall 03.

[0038] In another alternative embodiment, the connecting piece is a fixed column 04. The fixed column 04 is fixed on both sides of the fixed rack 01. A step 05 is provided on the channel wall 03. The fixed rack 01 is stuck on the step 05 through the fixed column 04, and the step 05 is used to adjust the height of the fixed column 04.

[0039] The fixed column 04 is made of high-strength and corrosion-resistant materials, such as stainless steel or galvanized steel. The shape of the fixed column 04 can be cylindrical, square, or other shapes customized according to actual needs. The fixed column 04 and the fixed rack 01 are integrally formed. The step 05 matching the fixed column 04 is set in advance on the channel wall 03. The number and position of the steps 05 should be planned according to the installation position and height requirements of the fixed rack 01. Different heights are provided between adjacent steps 05. Therefore, when the fixed column 04 is stuck on the step 05, the fixed column 04 can be moved to the step 05 at the corresponding height according to the actual water level height to realize the adjustment of the height of the fixed rack 01.

[0040] In an optional embodiment, the movable frame is composed of an intercepting rod 06, a connecting rod 07 and a side rod 08. The intercepting rod 06 is arranged parallel to the connecting rod 07. The two ends of the intercepting rod 06 are connected to the two ends of the connecting rod 07 through the side rod 08. The connecting rod 07 is used to be movably connected to the fixed frame 01, and the intercepting rod 06 is used to intercept debris in the water.

[0041] The movable frame mainly consists of three parts: an interception rod 06, a connecting rod 07 and a side rod 08. The interception rod 06 is used to directly intercept and collect debris in the water flow, such as leaves, plastic bottles, etc. The length and number of the interception rods 06 can be adjusted according to actual needs to cover a wider interception area. Two interception rods 06 can be set on the side rod 08 at the same time, and there is a certain distance between the interception rods 06. By setting two interception rods 06, the interception rate of debris is improved.

[0042] The connecting rod 07 is arranged parallel to the intercepting rod 06, and plays the role of connecting and supporting the intercepting rod 06. The side rod 08 connects the two ends of the intercepting rod 06 with the two ends of the connecting rod 07 to form a stable frame structure. The length and angle of the side rod 08 can be adjusted as needed to ensure the overall stability and interception effect of the movable frame.

[0043] In this optional embodiment, the surface of the interception bar 06 is provided with a plurality of protrusions. In this embodiment, the surface of the interception bar 06 is designed to have a plurality of protrusions, and the protrusions may be regular or irregular in shape. The protrusions can increase the contact area and friction between the interception bar 06 and the debris in the water flow, thereby more effectively intercepting and fixing the debris to prevent it from being washed away by the water flow. Under the impact of the water flow, the interception bar rotates with the connecting rod as a fulcrum, and the rotation amplitude is related to the flow velocity of the water flow.

[0044] In this optional embodiment, a groove 09 is provided on the fixing frame 01, and the groove 09 is used to accommodate the connecting rod 07. The connecting rod 07 is controlled to rotate in the groove 09. In this embodiment, a groove 09 is provided on the fixing frame 01, and the groove 09 is used to accommodate the connecting rod 07. The shape and size of the groove 09 match the connecting rod 07 to ensure that the connecting rod 07 can rotate smoothly in the groove 09.

[0045] In this optional embodiment, limiting plates 10 are respectively provided at the ends of both ends of the connecting rod 07, and the diameter of the limiting plates 10 is larger than the diameter of the connecting rod 07. The limiting plates 10 are used to limit the back and forth movement of the connecting plates on the fixing frame 01. In this embodiment, limiting plates 10 are respectively provided at both ends of the connecting rod 07, and the diameter of the limiting plates 10 is larger than the diameter of the connecting rod 07, and the diameter of the limiting plates 10 is also larger than the diameter of the bottom of the groove 09, so as to limit the range of back and forth movement of the connecting rod 07 on the fixing frame 01, and prevent it from being separated from the groove 09 or damaging the fixing frame 01 due to excessive water flow.

[0046] In an alternative embodiment, both the fixed frame 01 and the movable trash rack 02 are made of stainless steel, fiberglass or polyethylene. In this embodiment, by selecting high-performance materials such as stainless steel, fiberglass or polyethylene to manufacture the fixed frame 01 and the movable trash rack 02, not only the stability and durability of the trash interception device are improved, but also the maintenance cost and usage risk are reduced, providing strong support for water resource protection and water quality improvement.

[0047] In an alternative embodiment, there are 4 movable trash racks 02 arranged on the fixed frame 01. Each movable trash rack 02 is detachably connected to the fixed frame 01. The 4 movable trash racks 02 are sequentially and movably connected to the fixed frame 01 along the water flow direction. 2 movable trash racks 02 form a set of debris interception groups on the fixed frame 01. Therefore, there are 2 sets of debris interception groups on the fixed frame 01. In each set of debris interception groups, there is a height difference at the interception ends of the 2 movable trash racks 02, that is, the lengths of the side rods 08 of the 2 interception movable racks are different; by setting 2 sets of debris interception groups, the interception efficiency of debris can be improved. When the debris intercepted by any set of debris interception groups reaches the level that needs to be cleaned, lift this set up for cleaning. At this time, the other set still plays the role of debris interception, thus further reducing the situation of debris flowing into the downstream water body.

[0048] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
