according to the utility model, foreign matters and impurities filtered by the filter iron plates 31 are blocked and transferred by the filter screens 32 on the side walls of every two adjacent filter iron plates 31 and finally transferred to the outer ends of the filter screens 32 in the middle position, so that the problem that the filter iron plates 31 are blocked due to the fact that the filter iron plates 31 are rotated and inclined every time and the foreign matters are transferred to the rotating areas of the adjacent filter iron plates 31 is effectively solved.

As a further scheme of the utility model, the middle side walls of the two loading plates 11 are fixedly connected with fishing plates 35, two symmetrical screw rods 36 with opposite threads are rotatably arranged between the fishing plates 35, the outer ends of the screw rods 36 are in threaded connection with buckets 39, the rear ends of the buckets 39 are contacted with the outer wall of the filter screen 32, the two screw rods penetrate through the outer wall of one end of the upper fishing plate 35 and are coaxially and fixedly connected with driving wheels 37, the two driving wheels 37 are meshed, and the outer wall of one driving wheel 37 is meshed with a fishing motor 38; the debris of middle filter screen 32 front end are piled up too much, start fishing motor 38 and rotate to drive wheel 37 rotates, and redrive lead screw 36 rotates, thereby upwards rises scraper bowl 39, scrapes the debris on the filter screen 32 of front end and gets in scraper bowl 39, promotes upside salvage plate 35 lower extreme again, and it can to retrieve again, thereby has effectively solved the problem of artifical salvage.

As a further scheme of the utility model, the fishing motor 38 adopts a deceleration fishing motor to obtain larger torque.

As a further scheme of the present invention, a protective shell 40 is fixedly disposed at the lower end of the loading plate 11 at the lower end, an arc elongated slot 41 using the power rod 13 as a circle center is disposed on the upper end surface of the protective shell 40, and a bracket for fixing the filter iron plate 31 at the front end of the rotating plate 30 is sleeved in the arc elongated slot 41, so that under the condition that the operation of the equipment is not affected, the damage of the parts of the equipment is avoided, and the service life of the equipment is prolonged.

The working principle is as follows: when the utility model is used, the equipment is installed in a pipeline (the normal starting state is shown in figure 1, the whole equipment rotates ninety degrees in figure 1, the upper and lower positions in figure 1 are the right and left directions of the equipment, the left and right directions in figure 1 are the front and back directions of the equipment), when the gate needs to be closed, a crank 24 is used for anticlockwise rotating a variable speed driving disc 23 (as shown in figures 3 and 5, the rotating shaft point of a middle X bracket 16 is rotatably arranged at the upper end of a loading plate 11 when being seen from the right upper part of the equipment), the variable speed driving disc 23 rotates and drives a trigger rod 22 at the upper end of the symmetrical position of an X bracket 16 to anticlockwise rotate, the trigger rod 22 rotates and drives the X bracket 16 to reduce the front and back angles and increase the left and right angles, meanwhile, the X bracket 16 drives two outer X brackets 16 at four hinge points at two ends to perform the same operation action, so that the X bracket 16 which is not in the middle gets close to the middle, and drives each non-middle mobile rod 13 to move along a long circular groove 12 to the middle of the equipment when the X bracket 16 gets close to the middle, at the same time the variable speed drive disk 23 drives the lower gear lever 13 to rotate ninety degrees, and the gear lever 13 rotates ninety degrees causing the intermediate cutting plate 14 between the two load plates 11 to rotate ninety degrees, thereby completing the closed state; in the process, the other non-intermediate X-bracket 16 moves towards the middle and simultaneously drives the synchronous brackets 29 on the front and rear hinged points to move towards the middle along with the X-bracket 16, and simultaneously the front and rear two points of the X-bracket 16 move towards the front and rear outer sides, so that the hinged points between the two X-brackets 16 and the motor rod 13 are close to each other (as shown in fig. 5, when the front and rear two points of the X-bracket 16 move towards the front and rear outer sides, the sliding rod 25 on the hinged point between the two X-brackets 16 slides in the long circular hole formed in the synchronous bracket 29, so as to compensate the distance difference of the front and rear two points of the X-bracket 16 moving towards the front and rear outer sides), when the central hinged point of the two adjacent X-brackets 16 is close to each other (as shown in fig. 1, the driving device is driven by hinging of the end points of the plurality of X-brackets 16, when one of the X-brackets 16 acts, the other X-bracket 16 can quickly drive the other X-bracket 16 to rotate, thereby achieving the purpose of fast reaction speed and high efficiency), the trigger rack 27 on the sidewall of the synchronous bracket 29 drives the driving gear 28 coaxially and fixedly connected with the upper end of the driving rod 13 to rotate ninety degrees, thereby the cutting board 14 at the lower end also rotates, thereby completing the closing state (as shown in fig. 5, the limit plate 26 at the lower end of the synchronous bracket 29 slides in the oblong slot 12, thereby ensuring that the synchronous bracket 29 does not shake back and forth, thereby the trigger rack 27 is always meshed with the driving gear 28, thereby the driving rod 13 rotates), while the cutting boards 14 at the two ends move towards the middle and close (as shown in fig. 1, the cutting boards 14 close by closing by pressing another cutting board 14, thereby achieving the sealing effect, secondly, the cutting boards 14 slowly close, thereby the inside of the water flow is slowly cut off, the cutting plates 14 rotate to close and simultaneously inhibit the speed of water flow, and finally the water flow is completely closed), the motor rod 13 on the left and right sides drives the trigger rod 17 to move towards the middle along the inner wall of the long round hole 18 through the bracket, the trigger rod 17 moves to drive the semi-circular gate plate 19 to move towards the middle, the semi-circular gate plate 19 moves towards the middle to pull the sliding plate 20 to slide in the U-shaped sealing plate 21, and the cutting plates 14 at the outer ends of the left side and the right side rotate to close in the semi-circular gate plate 19, so that the edges are also in a sealing state; at this time, the cutting plate 14 completes the action of rotating and closing while moving to the middle, thereby completing the closing of the gate, and the state of opening the gate is opposite, which is not described herein.
