Specific embodiment
Below in conjunction with attached drawing, by example, the utility model is described in further detail.
Referring to attached drawing 1, a kind of mining large pump water suction mouth protecting device, includes valve body 1, water pump suction pipe 3, connecting rod
4, pin shaft 5, flap 6 and strainer 11, the valve body 1 are tubulose, and one end of valve body 1 is equipped with pin shaft 5, and the pin shaft 5 is equipped with two
The other end of a semicircular flap 6, valve body 1 is fixedly connected by connecting rod 4 with water pump suction pipe 3, and strainer is equipped in valve body 1
11, the strainer 11 is fixed on valve body 1 close to one end of water pump suction pipe 3.
In the present embodiment, referring to attached drawing 1,2, valve body 1 is tubular metal body, and a circle metal card is fixed in the upper end of valve body 1
Junctor 2, locking member 2 are coniform clamp, and lower end center line is equipped with pin shaft 5.
Water pump suction pipe 3 is located at the center of 1 upper end of tubular valve body, and is connected with water pump, and water pump suction pipe 3 passes through connecting rod
4 are connected as an entirety with valve body 1.
Referring to attached drawing 3, pin shaft 5 is the metallic rod of rule, and both ends are welded on the inner wall of valve body 1, passes through pin hole 7 and flap
6 rotation connections.Flap 6 shares two valves, for semicircle, can be freely rotated upwards by pin hole 7 around pin shaft 5.
Referring to attached drawing 4,5, filter element 8 is made of metal lining 9, hanging ring 10 and strainer 11, and filter element 8 can pass through
The rope being connected on hanging ring 10 is put into the space being made of valve body 1, locking member 2, water pump suction pipe 3, to enter Pump Suction
