Embodiment 1

[0024] Embodiment 1: A filter device for deep water intake and suction port and insulation for underwater pipelines. It is composed of different diameter pipes, plastic pipes, a water suction head 1 and a water suction pipe 2 formed by heat melting through the head. The water suction pipe 2 is connected to the suction pipe through the flange. Head 1 connection. Suction pipe 2 comprises metal interior pipe 21, as Figure 4 As shown, the outer surface of the inner tube is wrapped with a diving insulation jacket 22 for one week, and the alternate parts are bonded and fixed with nylon Velcro 23 after the wrapping. Waterproof membrane layer, rubber foam material layer, inner waterproof membrane layer, nylon fleece layer.

[0025] The water suction head is provided with a pipe body 12, and one end of the pipe body 12 is welded with a short pipe equal in diameter to the suction pipe 2, and the pipe diameter in the water suction pipe 2 is 800mm, and the short pipe diameter is also 80...

Embodiment 2

[0026] Embodiment 2: The structure of the suction pipe 2 is the same as that of Embodiment 1. The wing plate is provided with two parallel pieces, i.e. the upper wing plate 6 and the lower wing plate 7, forming a double-wing body 5, such as Figure 5 As shown, in order not to affect the quantity requirement of the filter mesh, the two wing plates are respectively located at the upper and lower top ends of the double-wing tube body 5 . Then, reinforcing ribs are respectively provided on both sides of the two wing plates to increase the welding strength with the double-wing tube body 5 .

Embodiment 3

[0027] Embodiment 3: The structure of the suction head 1 is the same as that of Embodiment 1. The suction pipe 2 is made of polypropylene PP plastic pipe, and the surface of the suction pipe 2 may not be equipped with a diving insulation jacket 22 .

[0028] When the above embodiments are installed and used, a vertical weight positioning device is hung on the water suction head 1 along the suction pipe 2 according to 10 meters. The vertical weight positioning device is provided with a counterweight 3, and the counterweight 3 passes through the fixed height rope. 4 is connected and fixed with the suction head 1.

Abstract

The invention relates to a water suction opening filtering and underwater pipeline insulation device for deep water taking. The device aims to solve the problems of algae and lower-layer poor-quality water at the position of a water suction opening for water drawing in lakes and reservoirs. The water suction opening filtering and underwater pipeline insulation device for deep water taking comprises a plastic water suction head and a water drawing pipe connected to one end of the water suction head. The water suction opening filtering and underwater pipeline insulation device for deep water taking is characterized in that the water suction head comprises a pipe body, a wing plate is arranged on the pipe body, and filtering screen holes are formed in the pipe body; the water drawing pipe comprises an inner pipe body, and a diving insulation jacket is arranged on the outer surface of the inner pipe body; a vertical weight positioning device is arranged at the position of the water suction head. Algae is skillfully prevented from being attached to the device through the wing plate, the optimal water suction layer is determined according to a height determining rope, the situation that the algae floating on the upper layer and sludge on the bottom layer or poor-quality water are sucked is directly avoided, the area of water filtering holes is increased, the flow rate of water inlets is lowered, and stable horizontal water flow can be obtained.

Description

technical field [0001] The invention relates to the technical field of pumping machinery and equipment, in particular to a filter device for a deep water intake suction port and an underwater pipeline insulation. Background technique [0002] More and more tap water is taken from lakes and reservoirs. Due to the bad behavior of human activities, the eutrophication of lake water quality has been accelerated, and the sign is the algae outbreak in the water body. Eutrophication has become a serious problem of water sources of lakes and reservoirs, and the deterioration of water quality has greatly increased the difficulty and cost of water purification in water plants. There are many water suction filter devices in the prior art, but these devices are basically ineffective to the long entangled algae of fiber. For example, the patent announcement number is CN2103040Y, a water intake filter equipped with a microporous filter tube, mainly composed of a water collection chamber, ...
