[0029] Example: A sewer foreign object isolation net, comprising an isolation net body;

[0030] The isolation net body consists of a through-hole nut 1, a main shaft 2, a secondary shaft 3, a sealing pressure spring 4, and an outer swing arm 5;

[0031] The upper part of the main spindle 2 has a first spindle hole 201 through it near its left end, and a second spindle hole 202 through it at its right end. The first and second spindle holes are machined on the same plane, which facilitates the identification of the direction after installation and rotation. The middle part of the auxiliary spindle 3 has an auxiliary spindle hole 301 through it. The main spindle 2 is set horizontally and the auxiliary spindle 3 is set vertically. The auxiliary spindle hole 301 on the auxiliary spindle 3 is connected to the first spindle hole 201 on the main spindle 2 by a rotary positioning bolt 6. The main spindle 2 and the auxiliary spindle 3 are connected in a cross shape. A return spring 7 is also provided at the rotary positioning bolt 6.

[0032] The right end of the main shaft 2 passes through the through nut 1, and the second main shaft hole 202 is located outside it. The sealing pressure spring 4 is sleeved between the main and auxiliary shaft connection and the bushing 101 of the through nut 1, and spring washers 8 are added at both ends. An O-ring seal 9 is provided between the spring washer 8 at the right end and the bushing 101 of the through nut 1. The outer swing arm 5 passes through the second main shaft hole 202.

[0033] The main functions of spring washer 8 are: the left end spring washer keeps the sealing spring opening vertical, reduces the spring friction coefficient when rotating the nut, and prevents damage to the spring; the right end spring washer keeps the sealing spring opening vertical, and the spring pressure is evenly distributed on the sealing ring, preventing water leakage.

[0034] Specific usage process:

[0035] The product consists of ten parts, among which the through-hole nut 1 is a welded component that makes up one part;

[0036] In its normal cross-shaped state, the product cannot enter the inner wall of the pipe through the sewer observation port. Therefore, by rotating the positioning bolt 6 at the connection between the main and auxiliary shafts, the auxiliary shaft 3 can be offset by 360 degrees, reducing the volume of the product entering the pipe cavity. A U-shaped groove 203 and a return spring 7 are added at the main shaft mounting positioning bolt, so that it automatically forms a cross structure when it enters the pipe. The principle is as follows: the two shafts are on the same straight line. Under the preload of the spring, the contact surface between the two shafts is large and the coefficient of friction is large. The two shafts remain stationary. When the external force causes them to offset more than 15 degrees along the center of the auxiliary shaft, the auxiliary shaft enters the U-shaped groove of the main shaft. Under the action of the spring, the auxiliary shaft is pulled into the U-shaped groove of the main shaft to form a cross shape.

[0037] A 30-degree chamfer 10 is designed at the bushing 101. The seal between the bushing 101 and the O-ring 9 will be squeezed inward more and more, and the seal will be more and more effective. Since the force of the spring is constant, the force of the outer swing arm 5 (rotating handle) is always the same. Moreover, unlike the O-ring installed inside the bushing, which will age and expand over time, making it impossible to rotate the outer swing arm 5.

[0038] This invention can intercept biodegradable substances such as water, paper towels, hard feces, and vegetable peels, as well as larger insoluble substances such as masks, rags, sanitary napkins, and plastic film bags. Through experiments and data analysis, using a 110mm diameter sewer observation port as a medium and adding an isolation net within it can fully achieve the above objectives.

[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
