[0024] In the figure: bent guide rod 901, salvage net 902, main load-bearing belt 9021, sliding buckle 903, rotating seat 9031, semi-circular sliding sleeve 9032, inner buckle rod 9033, ball 9034, towing rope 904, hanging rod 905, counterweight pendant 906, pull ring 907, emergency floating object salvage device 9, self-cleaning grille 13, control switching valve 24. Specific implementation method

[0025] The preferred solution is as Figures 1 to 7 shown. An emergency floating object salvage device for a sewage treatment plant includes a bent guide rod 901. A salvage net 902 is provided between two bent guide rods 901. A sliding buckle 903 is provided on the salvage net 902 for sliding along the bent guide rod 901; both ends of the salvage net 902 are used for installing a towing rope 904.

[0026] The bent guide rod 901 can be selected as an arc-shaped rod, a semi-circular rod, etc. The lower half of the bent guide rod 901 is used to sink into the water, and the sliding buckle 903 is used to sleeved on the bent guide rod 901. During use, all the sliding buckles 903 are uniformly sleeved on the bent guide rod 901 from one end of the bent guide rod 901, and then one end of the salvage net 902 is towed and slid through the towing rope 904, and the other end of the salvage net 902 is pulled cooperatively through the towing rope 904. When the sliding buckle 903 at one end of the salvage net 902 is towed to the other end of the bent guide rod 901, the salvage net 902 is completely unfolded. When there are too many floating objects on the sewage surface, lift the towing ropes 904 at both ends of the salvage net 902 simultaneously to salvage the floating objects on the sewage surface. After one salvage is completed, use the same method to deploy the salvage net 902 under the floating objects. The process of deploying the salvage net 902 will not be interfered by the floating objects.

[0027] Further, the bent guide rod 901 in this embodiment is a U-shaped guide rod, and the planes where the two U-shaped guide rods are located are parallel to each other; the lower half of the U-shaped guide rod is used to sink underwater.

[0028] The salvage net 902 is located between the two U-shaped guide rods. The length of the salvage net 902 is greater than the opening width of the U-shaped guide rod, and the width of the salvage net 902 is slightly greater than the distance between the two U-shaped guide rods. Attached Figure 1 The shown salvage net 902 is in a taut state, but in actual use, the salvage net 902 is preferably a structural net bag with a concave shape, which is conducive to salvaging more floating objects at one time.

[0029] Further, the sliding buckle 903 includes a rotating seat 9031, and the rotating seat 9031 is rotatably connected to the semi-circular sliding sleeve 9032; there are at least four rotating seats 9031, and the four rotating seats 9031 are respectively installed at the four corners of the salvage net 902, and the semi-circular sliding sleeve 9032 is used to slide on the bent guide rod 901.

[0030] The semi-circular sliding sleeve 9032 is in rotational fit with the rotating seat 9031. The semi-circular sliding sleeve 9032 is used to sleeved on the bent guide rod 901. The semi-circular sliding sleeve 9032 can rotate adaptively with the change of the orientation of the fishing net 902. The rotating seat 9031 and the fishing net 902 can be connected by a snap connection or by a tethering method.

[0031] Further, the arc of the semi-circular sliding sleeve 9032 exceeds 180 degrees. Inner buckling rods 9033 are respectively provided at both ends of the semi-circular sliding sleeve 9032. A ball 9034 is provided at the end of the inner buckling rod 9033. The ball 9034 is used for rolling fit with the bent guide rod 901.

[0032] The ball 9034 is used to reduce the resistance between the sliding buckle 903 and the bent guide rod 901, facilitating the smooth sliding of the sliding buckle 903 on the bent guide rod 901.

[0033] Further, a suspension rod 905 is provided on the side of the bent guide rod 901. The diameter of the suspension rod 905 is smaller than the diameter of the bent guide rod 901, and the diameter of the suspension rod 905 is smaller than the distance between the two balls 9034. The semi-circular sliding sleeve 9032 is used to slide along the bent guide rod 901, and the opening of the semi-circular sliding sleeve 9032 can pass through the suspension rod 905. The suspension rod 905 is used to connect the support frame.

[0034] The support frame suspends the two bent guide rods 901 in the water through the suspension rod 905. The bent guide rods 901 do not sink completely to the bottom, which facilitates the smooth movement of the sliding buckle 903 from one end of the bent guide rod 901 to the other end. The suspension rod 905 will affect the operation of the sliding buckle 903. In order to avoid the conflict between the sliding buckle 903 and the suspension rod 905, the structure of the sliding buckle 903 of the present utility model is refined. The specific structure is as follows: the semi-circular sliding sleeve 9032 is not completely closed, and there is enough space between the two balls 9034 to pass through the suspension rod 905. The diameter of the suspension rod 905 is smaller than the diameter of the bent guide rod 901, and the suspension rod 905 is L-shaped, so that the sliding buckle 903 can pass through the suspension rod 905 and will not detach from the bent guide rod 901. When it is necessary to salvage floating objects, the fishing net 902 can be completely removed from the bent guide rod 901.

[0035] Further, a counterweight pendant 906 is provided at one end of the fishing net 902.

[0036] When the fishing net 902 is installed on the bent guide rod 901, the counterweight pendant 906 can provide a downward pulling force, which can smoothly pull down one end of the fishing net 902.

[0037] Further, at least four pull rings 907 are provided on the fishing net 902. The pull rings 907 are connected to the towing rope 904. The towing rope 904 is towed by mechanical equipment or manually towed.

[0038] This device belongs to an emergency device and is used less frequently. If there are too many floating objects and the self-cleaning grille cannot handle a large number of floating objects in a short time, this device can be put into use. The traction method can be manual traction. If the manpower is not enough to clean the floating objects, a winch can be used to traction the traction rope 904.

[0039] Furthermore, the salvage net 902 includes four main load-bearing belts 9021. The four main load-bearing belts 9021 enclose a rectangular structure, and a net bag is woven on the four main load-bearing belts 9021. The length of the salvage net 902 is greater than the opening width of the U-shaped guide rod.

[0040] The four main load-bearing belts 9021 can be made of nylon belts, which can ensure sufficient mechanical strength while also having a certain degree of flexibility.

[0041] The location where this device is used is selected at the front end of the self-cleaning grille process. In some sewage treatment plants, two treatment processes are adopted in the dry season and the rainy season. The rainy season refers to the time period with sufficient rain. When the water level rises during the rainy season, there will be more floating objects. The inlet of the rainy season treatment process will pass through the self-cleaning grille. When the self-cleaning grille cannot quickly clean a large number of floating objects, this device can be put into use for emergency treatment.
