DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1

[0032] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a pollution interception method for automatically cleaning floating objects.

[0033] The floating objects are blocked by the first filter plate 204c and the second filter plate 204d. After the blocking is completed, the first filter plate 204c and the second filter plate 204d are lifted up and cleaned by the push assembly 101;

[0034] The floating objects are blocked by the first filter plate 204c and the second filter plate 204d, and then driven by the operation of the transmission assembly 203 to move the first filter plate 204c and the second filter plate 204d upward, and then the floating objects are cleaned by the pushing mechanism;

[0035] After the first filter plate 204c and the second filter plate 204d have finished blocking the floating objects, the pushing component 101 can be used to push the floating objects into the collection box 102c for collection, so as to facilitate subsequent processing;

[0036] After the floating objects are pushed out by the first filter plate 204c and the second filter plate 204d, the second filter plate 204d is driven again by the screw 203c to move downward and plug into the puncture plate 301, so that the second filter plate 204d can be punctured.

[0037] Example 2

[0038] Reference Figure 1 , 2 , 4, and 5 are the second embodiment of the present invention, which provides a blocking mechanism 200.

[0039] The blocking mechanism 200 includes a fixed rod 201 arranged at the top of the fence 100, a support rod 202 is arranged on one side of the fixed rod 201, a transmission assembly 203 is arranged on one side of the support rod 202, and a filter component 204 is arranged on the surface of the transmission assembly 203; the transmission assembly 203 includes a fixed block 203a arranged on one side of the support rod 202, a motor 203b is arranged on the top of the fixed block 203a, a screw rod 203c is connected to the output end of the motor 203b, a limiting rod 203d is rotatably connected to the bottom of the screw rod 203c, and the opposite side of the limiting rod 203d is fixedly connected to the inner wall of the fence 100; the filter component 204 includes a transmission block 204a arranged on the surface of the screw rod 203c, and a filter component 204 is arranged on the opposite side of the transmission block 204a. There is a filter frame 204b, a first filter plate 204c is arranged at the bottom of the filter frame 204b, and a second filter plate 204d is arranged on the front side of the first filter plate 204c; a puncture plate 301 is arranged at the bottom of the second filter plate 204d, and a plurality of puncture blocks 302 are arranged on the top of the puncture plate 301, and the puncture blocks 302 are used to puncture the second filter plate 204d; an extrusion groove 303 is opened on the opposite side of the fence 100, and a vertical rod 304 is arranged on the surface of the extrusion groove 303, and a spring 305 is sleeved on the surface of the vertical rod 304, and the bottom of the spring 305 is fixedly connected to the surface of the extrusion groove 303, and a connecting rod 306 is arranged on the top of the spring 305, and the bottom of the connecting rod 306 is fixedly connected to the top of the puncture plate 301.

[0040] Specifically, the transmission assembly 203 is driven by a motor 203b, which is installed on the top of the fixed block 203a, and its output end is transmission-connected to the screw 203c. When the motor 203b is started, the screw 203c starts to rotate. Since the bottom of the screw 203c is fixedly connected to the inner wall of the fence 100 through the limiting rod 203d, the rotation of the screw 203c is stable. The rotation of the screw 203c drives the transmission block 204a and the filter component 204 connected thereto to move, thereby filtering and cleaning floating objects.

[0041] Furthermore, when the motor 203b is started, the screw 203c starts to rotate. Since the bottom of the screw 203c is fixedly connected to the inner wall of the fence 100 through the limiting rod 203d, the filter component 204 is composed of a transmission block 204a, a filter frame 204b, a first filter plate 204c and a second filter plate 204d. When the transmission block 204a moves up and down with the screw 203c, the filter frame 204b and the first filter plate 204c and the second filter plate 204d thereon also move accordingly, and the floating objects are blocked in the fence 100, first passing through the first filter frame 204b and the second filter plate 204c and the second filter plate 204d thereon. Plate 204c performs preliminary filtration, and then passes through the second filter plate 204d for further filtration. The filtered floating matter is trapped on the second filter plate 204d and waits for subsequent processing. The puncture plate 301 is located at the bottom of the second filter plate 204d. When the second filter plate 204d moves downward, the puncture block 302 punctures the second filter plate 204d. The puncture action helps to clean the floating matter attached to the second filter plate 204d and prevent blockage. After puncture, the spring 305 returns to its original position, and the puncture plate 301 also drops accordingly, waiting for the next puncture action.

[0042] Example 3

[0043] Reference Figure 1 , 3 6 is a third embodiment of the present invention, which provides a pushing component 101 and a collecting component 102.

[0044] The pushing assembly 101 includes a support block 101a arranged on the top of the fence 100, an electric push rod 101b is arranged on one side of the support block 101a, the output end of the electric push rod 101b is connected to a pushing plate 101c, a guide block 101d is arranged on one side of the pushing plate 101c, the bottoms of the pushing plate 101c and the guide block 101d are in contact with the surface of the second filter plate 204d, two telescopic rods 101e are arranged at both ends of the right side of the pushing plate 101c, and the right sides of the two telescopic rods 101e are connected to the pushing plate 101c. A card block 101f is provided, and the bottom of the card block 101f is fixedly connected to the top of the fence 100; the collecting component 102 includes a plug-in block 102a arranged on the left side of the fence 100, and two plug-in blocks 102a are provided, and plug-in rods 102b are penetrated on the upper and lower sides of the two plug-in blocks 102a, and a collecting box 102c is provided on the top of the plug-in rod 102b; a plurality of through holes 307 are opened on the surface of the collecting box 102c, and the plurality of through holes 307 are used to filter the water source attached to the floating objects.

[0045] Specifically, the pushing component 101 can automatically push the floating objects on the second filter plate 204d to the collecting component 102 through the drive of the electric push rod 101b, without manual intervention, thereby greatly improving the cleaning efficiency. The setting of the collecting component 102 facilitates the subsequent processing of the floating objects.

[0046] Furthermore, the pushing assembly 101 is mainly composed of an electric push rod 101b, a pushing plate 101c, a guide block 101d, a telescopic rod 101e and a clamping block 101f. When the electric push rod 101b is started, its output end pushes the pushing plate 101c to move along the guide block 101d. This design ensures the stable movement of the push plate 101c. The bottom of the push plate 101c contacts the surface of the second filter plate 204d. Therefore, when the push plate 101c moves, it pushes the floating objects on the second filter plate 204d to the collection assembly 102. The telescopic rod 101e and the block 101f are used to provide additional support and stability for the push plate 101c to ensure that it will not be damaged due to uneven force during the pushing process. The collection assembly 102 consists of a plug-in block 102a, a plug-in rod 102b and a collection box 102c. The plug-in block 102a is fixed to the left side of the fence 100. The plug-in rod 102b runs through the upper and lower sides of the plug-in block 102a and is connected to the collection box 102c. 2c is connected to the top of the collection box 102c. When the pushing component 101 pushes the floating objects toward the collecting component 102, the floating objects are trapped in the collecting box 102c. The design of the collecting box 102c is convenient for disassembly and cleaning. The collecting box 102c can be easily removed by simply pulling out the plug rod 102b from the plug block 102a. A plurality of through holes 307 are provided on the surface of the collecting box 102c. The function of these through holes 307 is to filter the water source attached to the floating objects. When the floating objects are trapped in the collecting box 102c, the attached water source will flow out through the through holes 307 to achieve dry and wet separation. This design not only helps to reduce the accumulation of water in the collecting box 102c, but also facilitates the subsequent treatment and disposal of the floating objects.

[0047] The remaining structure is the same as that of Example 2.

[0048] Example 4

[0049] Reference Figures 1 to 6 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a trash rack for automatically cleaning floating objects.

[0050] When using the trash rack;

[0051] The transmission assembly 203 starts to work, the motor 203b drives the screw 203c to rotate, driving the transmission block 204a and the filter frame 204b to move up and down along the screw 203c. When the floating objects enter the area of ​​the fence 100 along with the water flow, they will be blocked and intercepted by the first filter plate 204c. The first filter plate 204c and the second filter plate 204d filter the floating objects and intercept larger debris.

[0052] When a certain amount of floating objects are accumulated on the second filter plate 204d, the filter frame 204b is driven to move upward by the screw rod 203c through electric operation, and the first filter plate 204c and the second filter plate 204d are driven to move upward at the same time. After the first filter plate 204c and the second filter plate 204d are moved, the electric push rod 101b is started to push the push plate 101c to move along the guide block 101d, and the floating objects on the second filter plate 204d are pushed toward the collecting assembly 102. At the same time, the telescopic rod 101e and the block 101f ensure the stable movement of the push plate 101c to avoid deviation.

[0053] When the floating objects are pushed into the collection box 102c, the attached water source is filtered through the through holes 307 on the surface of the collection box 102c to achieve dry and wet separation. The design of the plug-in block 102a and the plug-in rod 102b facilitates the disassembly and cleaning of the collection box 102c. When using the plug-in block 102a and the plug-in rod 102b, the collection box 102c only needs to be lifted upwards to separate the plug-in rod 102b from the plug-in block 102a.

[0054] After the floating objects are cleaned, the first filter plate 204c and the second filter plate 204d are moved downward and plugged into the puncture plate 301 through the transmission of the screw rod 203c. Under the action of the spring 305, the puncture plate 301 punctures the second filter plate 204d through the puncture block 302 to help clean the floating objects attached to the filter plate and avoid clogging. During the puncture process, the spring 305 is linked with the puncture plate 301 through the connecting rod 306 to buffer the resistance, so that the puncture plate 301 can have a certain buffer space when encountering resistance, thereby protecting the device from impact.

[0055] In rivers of different depths, the puncture plate 301 and the spring 305 are linked together by the spring 305 and the connecting rod 306, so that the puncture plate 301 can be squeezed to move downward, so as to adapt to rivers of different depths.

[0056] In summary: This trash rack that automatically cleans floating objects can achieve fully automatic interception, cleaning and collection through mechanical linkage, significantly reducing the need for manual intervention. Its dynamic filtration, puncture, buffer protection and modular collection designs make it suitable for scenes such as rivers and sewage treatment plants. It can efficiently handle floating objects and improve water quality management efficiency.
