Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and more specifically, it relates to a water surface garbage interception device for water conservancy engineering. Background Technology

[0002] A large amount of garbage floats in the river, and the garbage is spread downstream by the water flow.

[0003] To reduce the downstream spread of garbage, existing water conservancy projects use bridges and place floating rods in the bridge arches. The two ends of the floating rods are fixed to the bridge piers by ropes. The flexible connection of the ropes allows the floating rods to rise and fall with the water level, and the floating rods intercept garbage on the water surface.

[0004] However, the above solution also has its drawbacks. After the garbage is intercepted by the floating poles, the river cleaning staff regularly drive the boats to transport the garbage under the bridge to the garbage boats, making it difficult to collect the intercepted garbage on the shore.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1: A surface debris interception device for water conservancy projects, referring to... Figures 1-5 This includes: buoys 11 that are intercepted on the bridge piers. The number of buoys 11 corresponds exactly to the number of bridge openings. For example, if there are three bridge openings on the bridge body 01, then three buoys 11 are installed to ensure that each buoy 11 accurately covers the water surface area of ​​a single bridge opening without any interception gaps.

[0034] The length of a single buoy 11 is greater than the width of the water surface of the corresponding bridge arch, specifically as follows:

[0035] Length: The length of a single buoy 11 = the width of the water surface of the corresponding bridge opening + 2 × 0.5m; Example: If the width of the water surface of the bridge opening is 6m, then the length of buoy 11 is 7m.

[0036] Float 11 structure: Stainless steel metal rings are pre-set at both ends of float 11. The stainless steel metal rings are fixed to float 11 by screws or by heat fusion.

[0037] The surface of the float 11 is sprayed with red and white reflective markings every 1m to improve its visibility.

[0038] The float 11 is made of high-density polyethylene hollow rod, which has the characteristics of being resistant to acid and alkali corrosion to adapt to river water quality, resistant to ultraviolet aging for long-term outdoor use, and having stable buoyancy (density ≤0.95g / cm³).

[0039] Reference Figure 4 Adjacent floats 11 are connected in series using flexible connectors 12. The flexible connectors 12 are connecting ropes. In this embodiment, nylon ropes are used, mainly considering the characteristic that nylon is not easily degraded after long-term immersion.

[0040] The connecting rope is wrapped around and fixed to the metal ring at the end of the float 11 to achieve a soft connection to the adjacent float 11.

[0041] Three buoys 11 are connected to form an interception assembly 1, which intercepts garbage on the river surface. Figure 1 The direction indicated by the middle arrow is the direction of water flow.

[0042] Reference Figure 1 Insertion 21 and Insertion 22 are located on both sides of the riverbank.

[0043] Reference Figure 1 and Figure 2 A U-shaped metal ring is welded to the top of the first insert 21 to fasten the first pull rope 31; an L-shaped plate is welded to the lower end of the first insert 21, and the lower end of the first insert 21 is placed in the riverbank soil and fixed with cement.

[0044] Reference Figure 1 and Figure 3The top of the second insert 22 is welded with a cylindrical rope-winding post. The side of the rope-winding post is equipped with an M10 bolt locking device. When the second pull rope 32 is wound in place, the bolt is screwed in to tighten the pull rope and prevent it from loosening. An L-shaped plate is also welded and fixed below the rope-winding post. The lower end of the second insert 22 is placed in the riverbank soil and fixed with cement.

[0045] The length of the second pull rope 32 is greater than the length of the bridge so that it can be pulled from the opposite bank. In this embodiment, the length of the second pull rope 32 is three times the length of the bridge. In other embodiments, the length ratio can be 2 times, 4 times, or 5 times.

[0046] Both pull rope 31 and pull rope 32 are made of nylon rope with an anti-aging coating on the surface.

[0047] The working principle is:

[0048] Figure 5 Workers can untie the second rope 32 of the second insert 22, then take the extra second rope 32 and walk along the bridge body 01 to the other side, and pull the second rope 32 from the other side. In other embodiments, multiple people cooperate. One person can take the extra second rope 32 to the other side first, and then another person can untie the second rope 32 of the second insert 22 and then pull the second rope 32 from the other side.

[0049] When the second rope 32 is pulled from the opposite bank, the first rope 31 and the second rope 32 are located on the same bank. The staff must keep a certain distance from the first insert 21 so that the interception component 1 has enough deformation space when pulled. This is also the design purpose of the second rope 32 needing to be three times the length of the bridge. In other embodiments, the second rope 32 can be longer.

[0050] The interception component 1 uses a soft connection in the middle. The interception component 1 eventually moves towards the shore in a semi-enclosed manner and collects the garbage to the shore so that the staff can collect the garbage on the shore.

[0051] This core design achieves the goals of efficiently intercepting surface debris and facilitating convenient collection along the riverbank, and can be adapted to water conservancy scenarios with different numbers of bridge arches and river widths.

[0052] Example 2 differs from Example 1, as detailed below. Figure 6 The connecting rope outer sleeve 4 is provided as a flexible connector 12.

[0053] The flexible float 4 is made of EVA foam material, which has a density less than water to ensure it floats on the water surface. Both ends of the flexible float 4 are sealed with waterproof adhesive to prevent water ingress and increased weight. The buoyancy of the flexible float 4 is used to lift the connecting rope, reducing the time the rope is immersed in water.

[0054] Of course, flexible floats 4 can also be used on the parts of the first pull rope 31 and the second pull rope 32 that are on the water surface. The flexible floats 4 are designed to be soft and deformable.

[0055] Example 3 differs from Example 1 or Example 2, as detailed below. Figure 7 An interception net 5 is installed below the float 11.

[0056] The interception net 5 is a rigid net body, specifically made of rigid galvanized steel wire mesh. Under the action of gravity, the interception net 5 is set vertically downward. The mesh of the interception net 5 can trap some underwater debris, and the mesh can allow water to pass through.

[0057] The two ends of the interception net 5 are equipped with hanging rings, which are fastened to the stainless steel metal rings of the float 11 to achieve the installation of the two. The height of the interception net 5 is designed to be 10-20cm, and in this embodiment it is designed to be 15cm.

[0058] The buoyancy of the float 11 and the tension of the rope ensure that the float 11 floats on the water surface. The purpose of the interception net 5 is to intercept underwater garbage with a density similar to water.

[0059] Example 4, which differs from Example 1, Example 2, or Example 3, is described in detail below. Figure 8 The tail of the second pull rope 32 is equipped with a marker buoy 6. If the second pull rope 32 falls into the water, it can be located and quickly retrieved using the marker buoy 6.

[0060] The marker buoy 6 is a solid HDPE sphere with no hollow structure to prevent damage, water ingress, and sinking. The marker buoy 6 is a bright red color for easy identification by staff. A perforation is provided in the marker buoy 6, through which the second pull rope 32 is inserted and secured. In other embodiments, the marker buoy 6 and the second pull rope 32 are connected using a stainless steel universal buckle.

[0061] In other embodiments, a flexible sleeve may be fitted over the outer surface of the float 11 and fixed with adhesive, thus making the surface of the float 11 soft.

[0062] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
