[0002] With the acceleration of urbanization, the existing rainwater pipe network and sewage pipe network are already operating at overload, especially on rainy days, when large amounts of initial rainwater and mixed sewage enter natural water bodies such as rivers and lakes, carrying with them a large amount of ditch sludge, oil pollution, domestic garbage, etc. If not salvaged in time, floating objects will spread everywhere and are extremely mobile. Once summer comes, high temperatures will cause the bottom mud to ferment and float, and floating objects to rot, causing secondary pollution to natural water bodies such as rivers and lakes, making the water bodies further black and smelly, seriously affecting the normal production and life of surrounding residents.

[0003] In the prior art, there are mainly the following methods for salvaging floating objects such as floating mud, oil pollution, garbage, etc. on the water surface:

[0004] First, the manual salvage operation has many defects: ① The salvage workload is large, the frequency is high, and there is a phenomenon of incomplete salvage, which misses a large number of small particles of floating objects; ② On rainy days, it is greatly restricted by external factors such as rainfall, temperature, and water flow, and cannot be salvaged in time, resulting in a large number of floating objects entering the downstream water body; ③ There are safety hazards and high costs.

[0005] Second, the use of automatic salvage ships has the following defects: ① The cost of purchasing ships is high, and the subsequent maintenance costs and operator wages are high; ② The automatic surface floating object salvage ship is large in size and cannot perform floating object salvage operations in small rivers, harbors, canals, and culverts.

[0006] Third, the operating method using fixed intercepting devices has the following defects: ① It affects the navigation channels of other operating ships on the water surface; ② As the operation time increases, the intercepting device needs to clear the silt and dirt hanging or adhering to the surface, and the operating personnel need to clean it on the water surface, which is difficult to clean and poses a safety hazard; ③ At extreme water flow rates, the fixed intercepting device is easily washed away.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0030] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0031] like Figure 1-2 As shown, the utility model provides a pollution screen for automatic collection of online floating objects, comprising a pollution blocking device 1 and a traction device 2; the pollution blocking device 1 comprises a float 11, an interception screen 12 connected to the float 11, and a counterweight 13 arranged at the bottom of the interception screen 12; the traction device 2 comprises a traction cable drum 21 and two groups of traction components respectively connected to the two ends of the pollution blocking device 1; the traction component comprises a traction cable 22 wound around the traction cable drum 21 and a hook 23 connected to the end of the traction cable 22, and the hook 23 is used to connect with the pollution blocking device 1.

[0032] Through the above method, the pollution-blocking device 1 is placed in the river channel where floating objects need to be collected. The counterweight 13 can be used to make the lower end of the interception screen 12 vertically submerged in the water, and the upper end of the interception screen 12 remains floating under the action of the float 11, thereby forming a barrier in the water for intercepting floating objects; on this basis, since the two ends of the pollution-blocking device 1 are respectively connected to the traction device 2, by controlling the traction components in the traction device 2 that are respectively connected to the pollution-blocking device 1, the two ends of the pollution-blocking device 1 can be gradually closed to collect and gather the intercepted floating objects, which will not affect the navigation channels of other operating ships on the water surface, and is also convenient for unified cleaning of the collected floating objects, effectively reducing labor costs, and will not affect the normal drainage of the river channel, and has a good practical effect.

[0033] The pollution intercepting device 1 can be set at the water surface downstream of the outlet of a small river, harbor channel, or culvert waiting for treatment (hereinafter only the river is used as an example for explanation). In the intercepting state, it is preferably kept at an angle of 45 to 60 degrees with the cross section of the river to effectively intercept. In the intercepting state, the pollution intercepting device 1 is unfolded, and its two ends can be connected by a traction device 2, or other fixing devices can be used to detachably fix the two ends of the pollution intercepting device 1 to the two banks of the river as needed. If other fixing devices are used for fixing, when it is necessary to close and collect, it is necessary to first unlock the fixing device, and then use the traction device 2 to pull its two ends.

[0034] Specifically, in some embodiments of the present invention, the float 11 can be an integrated, bendable columnar structure, or a bendable structure formed by combining and connecting a plurality of float units, which can float on the water surface and can be closed under the traction of both ends, all of which belong to the protection scope of the present invention. The size of the float 11 can be adjusted according to actual needs. For example, in some embodiments of the present invention, the diameter of the float 11 is preferably 150 to 250 mm, and more preferably 200 mm.

[0035] In some embodiments of the present invention, the interception screen 12 is a mesh structure so as not to affect the water flow while intercepting floating objects. The material of the interception screen 12 can be selected according to actual needs, as long as it can remain firm in the water. For example, in some embodiments of the present invention, a 40-mesh PE net is specifically used as the interception screen 12, and the width of the interception screen 12 is preferably 400-600 mm to achieve a better interception effect.

[0036] In the pollution intercepting device 1, the function of the counterweight 13 is to keep the lower end of the interception screen 12 submerged in water. The material can be selected according to actual needs, as long as the density is greater than that of water and does not react in water; all belong to the protection scope of the present utility model. Preferably, the number of counterweights 13 can be multiple, and each counterweight 13 is arranged at equal intervals at the bottom of the interception screen 12 to ensure that all parts of the bottom of the interception screen 12 are vertically submerged in water. Among them, the weight of each counterweight 13 is preferably 80 to 120g, and the spacing between adjacent counterweights 13 is preferably 80 to 120mm. For example, in one embodiment of the present utility model, the counterweight 13 is a lead sinker, each counterweight 13 is 100g, and the spacing between adjacent counterweights 13 is 100mm.

[0037] Please join us Figure 3 In some embodiments of the utility model, the traction cable drum 21 includes a fixed bracket and two groups of rotating components respectively arranged at both ends of the fixed bracket; the fixed bracket can be fixedly arranged on the river bank on one side of the river channel, and each group of rotating components is used to connect with a group of traction components. In this way, the traction cables 22 in the two groups of traction components can be controlled by a traction cable drum 21, which not only makes the structure simpler, but also is more conducive to finally closing the two ends of the pollution-blocking device 1; and the two groups of traction components are respectively controlled by the two groups of rotating components, which can make the two groups of traction components relatively independent, and can pull the two ends of the pollution-blocking device 1 with different amplitudes, making the adjustment more convenient. In some embodiments of the utility model, the rotating component preferably includes a rotating shaft and a hand crank connected to the rotating shaft, and the traction cable 22 is evenly wound around the rotating shaft. By rotating the hand crank to drive the rotating shaft to rotate, the traction cable 22 can be retracted and released.

[0038] More specifically, in one embodiment of the utility model, the traction cable drum 21 specifically adopts a double-groove drum, in which each groove body has an outer diameter of 240 mm and a width of 900 mm; the traction cable 22 wound on the traction cable drum 21 is a steel wire rope with a diameter of 20 mm, and the hook 23 is a 304 stainless steel hook weighing 0.656 kg to improve the firmness of the traction device 2.

[0039] More preferably, in some embodiments of the present invention, each group of the traction assembly further includes a traction sheave 24, which can be arranged on the side wall of the river channel, and the traction cable 22 passes over the traction sheave 24 and is connected to the trash intercepting device 1. In this way, the traction sheave 24 can be used to guide the traction cable 22, so as to facilitate the control of the direction of the traction cable 22. In one embodiment of the present invention, the traction sheave is a 304V-type 68 tripod wheel.

[0040] Combine the following Figure 4-5 The working principle of the pollution blocking screen for automatic online floating object collection provided by the utility model is described as follows:

[0041] In actual application, the pollution blocking device 1 can be set in advance at the water surface downstream of the outlet of the river, so that the pollution blocking device 1 is fixed to both sides of the river and forms an angle of 45°. Figure 4 The lower end of the interception screen 12 in the trash intercepting device 1 is vertically submerged in the water under the action of the counterweight 13, and the upper end of the interception screen 12 is extended out of the water under the action of the float 11, so as to intercept floating objects such as garbage.

[0042] When floating objects need to be collected or a large ship needs to pass through the waters, the two groups of rotating components in the traction cable drum 21 are rotated respectively to drive the traction cable 22 to be wound and wound, so that the hook 23 at the end of the traction cable 22 pulls the two ends of the pollution interception device 1. During the traction process, the pollution interception device 1 can collect floating objects such as floating bottom mud, oil pollution and garbage on the water surface along the way, and the floating objects are collected and gathered in the process of the two ends of the pollution interception device 1 gradually closing, so as to be uniformly and centrally removed from the waters.

[0043] Through the above-mentioned method, the online floating object automatic collection pollution blocking screen provided by the utility model can effectively intercept and collect floating objects on the water surface without affecting the navigation of ships and flood discharge and drainage, and can meet the needs of practical applications.

[0044] In summary, the utility model provides a pollution screen for automatically collecting floating objects online, including a pollution screen 1 and a traction device 2; the pollution screen 1 includes a floating body 11, an interception screen 12 connected to the floating body 11, and a counterweight 13 arranged at the bottom of the interception screen 12; the traction device 2 includes a traction cable drum 21 and two groups of traction components respectively connected to the two ends of the pollution screen 1; the traction component includes a traction cable 22 wound on the traction cable drum 21 and a hook 23 connected to the end of the traction cable 22, and the hook 23 is used to connect with the pollution screen 1. In the above manner, the utility model can effectively intercept floating objects on the water surface by using the pollution screen 1, and at the same time, use the traction device 2 to tow the pollution screen 1, so that the pollution screen 1 can collect and gather floating objects while intercepting, so that it will not affect the navigation channel of other operating ships on the water surface, and it is also convenient to uniformly clean up the collected floating objects, effectively reducing the labor cost, and not affecting the normal drainage of the river channel, and has a good practical effect.

[0045] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
