[0040] The identification end placed on the execution device includes a camera 9 and a density sensor 13, which are respectively used for monitoring the color change and the density change of the water in the channel, and through the combination of image recognition technology and density change, the area and diffusion degree of the plastic floating object are determined, and the information is transmitted to the control end;

In the embodiment, the diameter of the small hole is 0.03 meters, and the distance between two adjacent small holes is 0.2 meters. After the gas enters the inflation pipe 4 through the sliding inflation interface 3, the gas is sprayed through the nozzle to form a plurality of bubble plumes, which jointly form a bubble barrier to intercept the floating plastic.

[0044] The positioner 6 comprises an outer shell 14, the left side of the outer shell 14 is located in the same vertical plane as the left side of the hollow end 15, a hollow groove is arranged on the right side of the outer shell 14, and the homopolar electromagnet comprises a fixed core 11 and a movable core 12, wherein the fixed core 11 is fixedly connected with the inner wall of the hollow groove, the movable core 12 is slidably connected with the inner wall of the hollow groove, the outer surfaces of the fixed core 11 and the movable core 12 are both wound with wires 10 in opposite directions, and the left side of the movable core 12 is in close contact with the right side of the fixed core 11 in the static state, and the fixed core 11, the movable core 12 and the two sections of wires 10 wound in opposite directions jointly form the homopolar electromagnet, which is convenient for electrically controlling the diving depth of the inflation pipe 4.

[0045] A first inclined surface which is matched with the holder 5 is arranged on the right side of the outer shell 14, the end of the movable core 12 is arranged as a second inclined surface which is matched with the right side of the outer shell 14, and the front end of the holder 5 is in contact with the second inclined surface. Under the lubrication of the water body, the abrasion can be reduced.

[0046] The sliding inflation interface 3, the telescopic holder top 7, the fixed core 11 and the two sections of wires 10 corresponding to the movable core 12 are all electrically connected with the control end.

[0047] The execution device is at an angle of 45° with the water flow vertical plane, that is, the longitudinal reference section plane which is perpendicular to the water surface, and the whole execution device is inclined, so that the floating plastic can be automatically collected in combination with the water flow while the interception is considered; the included angle between the positioner 6 and the sliding inflation interface 3 is set as an acute angle, and the sliding inflation interface 3 is at an angle of 25° with the slide rod 2 in the static state. At this time, the sliding inflation interface 3 of the execution device is in the self-locking state. Under the lubrication condition, the friction coefficient between cast iron and rubber is 0.5, and under this condition, the sliding inflation interface is in the self-locking state, that is, there is always a force to keep the sliding inflation interface and the slide rod in the static state.

[0048] Camera 9 is placed on the top of the slide rod 2, and the density sensor 13 is placed on the upstream direction of the inflatable pipe 4.

[0049] The slide rod 2 is set as a combination of a cylinder and two cuboids, which is erected on the upstream side of the water conveying channel, and the outer side of the slide rod 2 is sleeved with waterproof rubber, which protects the slide rod 2, reduces the corrosion of the slide rod 2 by water, increases the service life of the execution device, and increases the friction factor to facilitate the formation of self-locking with the sliding inflatable interface 3.

[0050] The sliding inflatable interface 3 and the shell 14 are both made of cast iron.

[0051] When the density sensor 13 and the camera 9 of the identification end detect plastic floating objects in the water body, the collected information is quickly transmitted to the background control end. The control end immediately analyzes and calculates to determine the required inflatable pipe diving depth and the pump air volume for intercepting these plastics. Then, the pump air volume and diving depth instructions are sent to the execution device. After receiving the instructions, the execution device drives the electric push rod 7 to operate, and at the same time, the lead wire 10 in the shifter 6 is connected, so that the fixed core 11 and the moving core 12 form a same-pole electromagnetic iron. Under the action of magnetic force, the fixed core 11 and the moving core 12 repel each other, and the right end of the moving core 12 lifts the holder 5. Since the holder 5 is rigidly connected with the sliding inflatable interface 3 and overlaps with the inflatable pipe 4, at this time, the sliding inflatable interface 3, the inflatable pipe 4 and the holder 5 rotate around the contact axis of the sliding inflatable interface 3 and the left side of the slide rod 2. The inflatable pipe 4 forms a certain angle with the horizontal plane, and the angle between the sliding inflatable interface 3 and the slide rod 2 is greater than 25°, so the self-locking condition is broken, and the sliding state is entered. Under the synergistic action of the electric push rod 7, the shifter 6 and the thick spring 8, the sliding inflatable interface 3 starts to slide up and down. When the shifter reaches the specified position, the entire execution device is powered off, the magnetic force of the electromagnetic iron disappears, and the moving core 12 is again attached to the fixed core 11 under the pressure of the holder 5, so that the inflatable pipe 4 is fixed at the new position, thereby realizing the adjustment of the bubble generation height according to the actual demand and the efficient interception of floating plastics.

[0052] In the specific embodiment, the water conveying main channel is B, the depth is H, the base 1 has a size of 0.54×0.22×0.1H m, and is made of C35 concrete. The hollow end 15 of the slide rod 2, the sliding inflatable interface 3 and the shifter 6 are made of cast iron, and the density is 7.5 g / cm 3 , wherein the height of the slide rod 2 above the base is 1.2H, the total width is 0.2m, the diameter of the middle cylinder is 0.1m, the width of the side cuboid is 0.05m, and the surface is coated with butyl rubber as waterproof material. The size of the hollow end of the sliding inflatable interface is 0.33×0.12×0.05m, and the thickness is 0.002m. The size of the solid end is the same as that of the hollow end, and the solid end is made of hard PVC material, and the density is 1.3 g / cm 3The size of the transducer 6 is 0.43*0.12*0.05m. The friction factor of butyl rubber and cast iron under water lubrication is 0.5. When the included angle between the sliding inflation interface 3 and the slide rod 2 is less than or equal to 25°, the device is in a self-locking state. The inflation pipe 4 is made of cast iron pipe, with a length of 1.414B, an inner diameter of 0.03m, and an outer diameter of 0.032m. Small holes with a diameter of 0.03m are opened on the upper surface every 0.2m, and a nozzle is installed at each small hole. The holder 5 is made of hard PVC, with a density of 1.3g / cm 3 , a rectangular cross-section of 0.032*0.02m, and its ends are lapped in the middle of the inflation pipe 4. In the static state, the transducer 6 is kept at a distance of 0.1H from the front end of the sliding inflation interface 3, and the minimum distance between the transducer 6 and the base 1 is 0.1H.

[0053] Specifically, it is known that the friction factor of cast iron and rubber is 0.5, the material density of the slide rod 2, the hollow end of the sliding inflation interface 3, and the inflation pipe 4 is 7.5g / cm 3 , and the material density of the holder 5 is 1.3g / cm 3 The size of the hollow end of the sliding inflation interface 3 is 0.33*0.12*0.05m, and the thickness is 0.002m. The solid end has the same size as the hollow end, and is made of hard PVC material with a density of 1.3g / cm 3 The length of the inflation pipe 4 is 1.414B, the inner diameter is 0.03m, and the outer diameter is 0.032m. It can be calculated that the overall volume of the sliding inflation interface 3 is 0.00372m 3 , and the overall mass is 2.578kg. The related parameters of the inflation pipe 4 and the holder 5 are shown in Table 1.

[0054] Table 1 Related parameters of inflation pipe and holder

[0055]

[0056] Specifically, the force analysis of the execution device in the static state is shown in Figure 11 . After force translation, it can be known that the force at the force point is the gravity G1 of the sliding inflation interface 3, the inflation pipe 4, and the holder 5; the moment M1 generated after the translation of G1; the pressure P and the supporting force F1 of the slide rod 2 on the sliding inflation interface 3, the inflation pipe 4, and the holder 5; the friction force f that prevents the sliding inflation interface 3, the inflation pipe 4, and the holder 5 from sliding downward; the supporting force F2 of the transducer on the sliding inflation interface 3, the inflation pipe 4, and the holder 5; the moment M2 generated after the translation of F2; and the balance moment M3 of the slide rod itself. Since the execution device is in a self-locking state when it is static, the overall force is in a balanced state, and in the horizontal direction:

[0057] P*cosθ=F1+F2

[0058] In the vertical direction, there is:

[0059] f = μ (F1 - F2) = G1 + P sin θ

[0060] Moment on the upper:

[0061] M1 + M2 + M3 = 0

[0062] Wherein, μ is the dynamic friction factor, empirical value, known gravity acceleration is g = 9.8 m / s 2 , θ = 25 °, μ = 0.5, F2 = 0, then M2 = 0, the moment is in the positive direction with the same direction of the mark, and the channel water depth is 3 m, the required bending strength σ of the sliding rod 2 can be calculated, and the calculation results are shown in table 2. Figure 11

[0063] Table 2 data table of stress analysis calculation results

[0064]

[0065] Therefore, according to the required bending strength σ of the sliding rod 2, the material meeting the strength requirement can be selected for manufacturing.

[0066] Specifically, the identification end takes pictures when the floating plastic on the water surface is away from the vertical channel section B (B is the channel width) of the sliding rod by a distance, measures the water density at the same time, and transmits the information to the control end. The control end imports the processed information into the BP neural network through information preprocessing, calculates the floating plastic area S and the diffusion degree γ (the area proportion of floating plastic in unit area of water area), and generally, the air flow Q 气 Is fixed, the channel flow is Q, the interception efficiency is related to the diving depth h. Due to the characteristics of the bubble, with the increase of the diving depth h, the number of bubbles on the water surface decreases, and the control and collection efficiency decreases; the diving depth h decreases, the control efficiency increases, but the water disturbance increases, which is not conducive to the concentration of plastic floating objects; it is necessary to ensure that 0.24 < h / H < 0.4, so as to achieve sufficient water surface bubbles and controllable water disturbance. The channel flow Q, the air flow Q 气 , the floating plastic area S, the diffusion degree γ and the condition 0.24 < h / H < 0.4 are imported into the BP neural network for prediction, so as to calculate the reasonable diving depth.

[0067] The preferred embodiments of the utility model are described in detail above, but the utility model is not limited to the specific details in the above embodiments, and various equivalent transformations of the technical solutions of the utility model can be made within the technical concept of the utility model, and these equivalent transformations all belong to the protection scope of the utility model.​
