In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant to the invention.
As depicted in figs. 1 and 2, a kind of big flow jet pump, including the pump housing 1, set that there are one sliding slot, institutes on the pump housing 1
Sealing plate 2 there are one being set at sliding slot is stated, a transmission shaft 3, the end connection of the transmission shaft 3 are connected on the sealing plate 2
There are a drive link 4, the upper and lower ends of the drive link 4 to be all provided with there are one sliding block 5, each sliding block 5 is arranged at a guide rail 6
On, and each sliding block 5 is all connected with there are one adjustable plate 7, the guide rail 6 is arranged on the pump housing 1, and guide rail 6 is arc-shaped, and arc
The center of circle is on the pump housing 1；The pump housing 1 includes work water inlet 1-1, sucks water inlet 1-3, mixing chamber 1-4 and discharge outlet 1-6,
The work water inlet 1-1 and sucking water inlet 1-3 are connected to by mixing chamber 1-4 with discharge outlet 1-6, are also set in the pump housing
There are one the outer ends of nozzle 1-2, the nozzle 1-2 to be connected to work water inlet 1-1, and inner end is located at the entrance of mixing chamber 1-4,
And the interior end cross-sectional area of nozzle 1-2 is less than outer end cross-sectional area, which can increase flow velocity；The both sides of the mixing chamber 1-4 are
One piece of elastic plate 1-5, two pieces of elastic plate 1-5 and two sliding blocks 5 are corresponded and are interconnected；The middle part of the mixing chamber 1-4
If there are one ball 8, the ball 8 is connect with transmission shaft 3；The guide rail 6 is located at the both ends of elastic plate 1-5, and with pump
Body 1 is fixedly connected；The both ends of every piece of elastic plate 1-5 are connect with the pump housing 1, are set on the outside of every piece of elastic plate 1-5 there are one fluting,
The adjustable plate 7 is located at the inside of corresponding fluting；Sealing strip is equipped between the sealing plate 2 and sliding slot；In work water inlet
Flange there are one being all provided at 1-1, sucking water inlet 1-3 and discharge outlet 1-6；The periphery of the pump housing 1 is coated with anti-decaying paint.
As shown in figure 3, the junction of the transmission shaft 3 and sliding slot is set, there are one through-holes 9, and the both ends of the through-hole 9 are all provided with
There are one steel ball 11, interconnected by an elastic parts between two steel balls 11, the inner wall of the sliding slot is equipped with and steel ball
11 matched limiting slots, the elastic parts are spring 10, and spring 10 is in compressive state when transmission shaft 3 moves always
It waits, steel ball 11 will be squeezed by the cell wall of sliding slot to the inside of through-hole 9, after transmission shaft 3 is moved to designated position, steel ball 11
