2 are set, and the triggering compression bar c-2 is when lifting on basket grid c with can bend, in order to from the cavity of the upper end pumping plant cylinder a
It takes out.
Specifically used method:
A kind of grid device applied to prefabricated pumping plant of the present invention passes through the hand basket sheet of basket grid c under normality
Body c-1 block is filtered in water inlet pipe b exit site, and is lifted on hand basket ontology c-1 and passed through the spare of spare grid d when clearing up
Grid ontology 41a is filtered:
Embodiment one, hand basket ontology c-1 is filtered water inlet pipe b under normality:
Under normality, the hand basket ontology c-1, triggering compression bar c-2 downlink squeeze the trigger device 2, the triggering cross bar
23, sliding sleeve 22 overcome the first pressure spring 26 active force and downlink；
The input rack gear of 22 rear end face of sliding sleeve, which acts on the right side, which sets gear wheel 31c, makes its rotation, the right side
Set that gear wheel 31c drives the right side to set pinion gear 32c, gear wheel 32b rotation is set on a left side, the left side is set gear wheel 32b and finally driven

Filter, as shown in Figure of description 4.
Embodiment two, when lifting cleaning on hand basket ontology c-1, spare grid ontology 41a is filtered water inlet pipe:
The hand basket ontology c-1 needs lifting to be lifted to outside pumping plant cylinder a using the more sundries of accumulation after a period of time
It is cleared up.
Once uplink, first pressure spring 26 acts on the triggering cross bar by the hand basket ontology c-1, triggering compression bar c-2
23,22 uplink of sliding sleeve；
The input rack gear of 22 rear end of sliding sleeve, which acts on the right side, which sets gear wheel 31c, rotates backward it, described

Its plane is vertical with water inlet pipe b water (flow) direction under grid ontology 41a normality, and the spare grid ontology 41a is in water inlet pipe b
Water flow is filtered, as shown in Figure of description 3.
A kind of grid device applied to prefabricated pumping plant of the present invention can also adjust the spare grid ontology
The angle of 41a.For example, when the hand basket ontology c-1, triggering compression bar c-2 uplink cleaning, where the spare grid ontology 41a
Plane can not be exactly perpendicularly to water (flow) direction, lead to that complete filter effect cannot be played.
When the hand basket ontology c-1, triggering compression bar c-2 are cleared up by lifting uplink, maintenance personal can pass through people
Hole, which enters, carries out repair and maintenance inside pumping plant cylinder a, can the angle of spare grid ontology 41a be checked and be adjusted at this time
It is whole:
23 downlink a small distance of triggering cross bar that artificial downlink presses the trigger device 2 can drive spare grid sheet
Body 41a rotates certain low-angle.It will be apparent that the triggering cross bar 23 is in upper lift posture and pushes the operation between posture
Section, the spare grid ontology 41a rotational angle are exactly 90 °.But the initial attitude of the spare grid ontology 41a can
It can shift: when the triggering cross bar 23 drops to bottom, if plane and water flow where the spare grid ontology 41a
Direction is consistent, then the posture of the spare grid ontology 41a is correct；The plane where the spare grid ontology 41a deviates from
Water (flow) direction then illustrates that its posture shifts, and needs to be corrected.
Spare grid ontology 41a attitude updating method: it will be apparent that described standby when the definition pushing triggering cross bar 23
90 ° are rotated forward with grid ontology 41a, then the spare grid ontology 41a rotates backward 90 ° when unclamping the trigger device 2.
Wherein, pushing and lift primary triggering cross bar 23 becomes the action cycle of primary triggering cross bar 23.
By taking positive direction deviation has occurred relative to water (flow) direction in spare grid ontology 41a described under normality as an example, to spare
The adjusting of grid is as follows:
When pushing the triggering cross bar 23, transmission device 3 is subjected to interruption appropriate, the spare grid ontology 41a is just
90 ° are discontented with to rotational angle: being pulled the adjusting transverse slat 52a to the right, driven the adjustment collar 51 to move right, the adjusting
Lantern ring 51 drives clamping rings 51, the right side to set pinion gear 32c and the elastic force of the second pressure spring 53 is overcome to move to right, and pinion gear 32c is set on the right side
It sets gear wheel 32b with a left side to disengage, the transmission of the transmission device 3 is interrupted；And when the upper lift triggering cross bar 23, unclamp institute
Stating adjusting transverse slat 52a resets the transmission of transmission device 3, and the spare grid ontology 41a rotates backward angle equal to 90 °.I.e.
Within the action cycle of a triggering cross bar 23, the spare grid ontology 41a has rotated backward certain angle.It repeats above-mentioned dynamic
Make, until the spare grid ontology 41a posture stops when correct.
And when the spare grid ontology 41a has occurred opposite direction relative to water (flow) direction and deviates, then pushing triggering
Cross bar 23 is and the interruption transmission device 3 appropriate when upper lift triggers cross bar 23 so that transmission device 3 is always maintained at effective connection
Connection, then spare grid ontology 41a can be made to rotate forward within the action cycle of a triggering cross bar 23.It repeats above-mentioned
The posture of spare grid ontology 41a can be then corrected by movement.
