Further: the limiting unit comprises an installation seat 35 arranged at the lower end of the installation plate 18, and a limiting rod 33 is longitudinally and elastically arranged on the installation seat 35 through a first spring 34 and a fixing part 32 in a penetrating manner; when the first spring 34 is free, the limiting rod 33 can be located on the moving path of the free end of the second elastic telescopic rod 21 to limit the movement of the free end; the lower end of the limiting rod 33 is provided with a driving part 33-1; the upper end of the second rack 22 is fixedly provided with a wedge-shaped extrusion block 23, and the extrusion block 23 can extrude the limiting rod 33 downwards through the driving part 33-1, so that the limiting rod 33 is separated from limiting the second elastic telescopic rod 21.
The intercepting net replacing device comprises a net bag 10 with limiting lugs 10-1 at two sides; the mounting plate 18 is internally and symmetrically provided with second elastic telescopic rods 21 in a sliding manner, and the end parts of the second elastic telescopic rods 21 can push the net bag 10 above the mounting plate 18 into an intercepting station through a slideway in the mounting plate 18; a limiting groove 25-1 for limiting the net bag 10 to move downwards is arranged below the mounting plate 18, the limiting groove 25-1 is fixedly arranged in a limiting shell 25 fixedly connected with the mounting plate 18, and the diameter of the inner wall of the limiting shell 25 is matched with the diameter of the upper end of the net bag 10; the upper end of the limiting groove 25-1 is provided with a damping section 29 (the damping section 29 can enable the net bag 10 to resist water pressure for a period of time, and the net bag 10 is prevented from directly falling along the limiting groove 25-1, so that impact is generated between the net bag and the ejector rod 13); the limit groove 25-1 is internally provided with a mandril 13 in a sliding way; a first rack 14 is fixedly arranged on the outer side of the ejector rod 13, the first rack 14 is meshed with a driving gear 17, and a second rack 22 is meshed on the upper side of the driving gear 17; the second rack 22 is not coincident with the first rack 14 path; the end part of the second rack 22 is fixedly connected with the end part of the second elastic telescopic rod 21 through a connecting plate 20; the rear part of the connecting plate 20 is connected with a fixing plate 9 through a return spring 11, and the fixing plate 9 is fixedly connected with the shell 5; the free end part of the second elastic telescopic rod 21 is provided with a limiting unit; the limiting unit is used for limiting the movement of the free end of the second elastic telescopic rod 21, and the limiting of the second elastic telescopic rod is cancelled when the net bag 10 is replaced.
Further: the limiting unit comprises an installation seat 35 arranged at the lower end of the installation plate 18, and a limiting rod 33 is longitudinally and elastically arranged on the installation seat 35 through a first spring 34 in a penetrating manner; when the first spring 34 is free, the limiting rod 33 can be located on the moving path of the free end of the second elastic telescopic rod 21 to limit the movement of the free end; the lower end of the limiting rod 33 is provided with a driving part 33-1; the upper end of the second rack 22 is fixedly provided with a wedge-shaped extrusion block 23, and the extrusion block 23 can extrude the limiting rod 33 downwards through the driving part 33-1, so that the limiting rod 33 is separated from limiting the second elastic telescopic rod 21.
Because the power of the suction pump is constant, when the interception net needs to be replaced, the suction pump is often required to be closed or a part of the pipe body is required to be closed, which can cause the instantaneous great change of the pipe pressure, further causes the water hammer effect and damages the pipe body.
When in use: firstly, a net bag 10 (namely an intercepting net) is arranged at a working position (namely the position of a reference numeral 10 in figure 9), and then a standby net bag 10 is arranged at the front end of an installation plate 18 (shown in figures 4 and 5); when water flows through a station, the net bag 10 can generate a filtering effect on the water flow, and as time goes on, sundries accumulated in the net bag 10 are more and more, the water outlet area of the net bag becomes smaller, so that the pressure applied to the whole net bag 10 is increased, and the limiting lug 10-1 of the net bag 10 partially moves downwards along the limiting groove 25-1 and overcomes the force of the ejector rod 13; at the same time: the mandril 13 drives the first rack 14 to move downwards, so as to drive the driving gear 17 to rotate, and therefore the connecting plate 20 is driven by the second rack 22 to move leftwards (for example, 9 is combined with the figure 4) against the elastic force of the return spring 11; when the connecting plate 20 moves leftwards, the free end of the second elastic telescopic rod 21 is limited by the limiting rod 33, so that the leftward movement of the connecting plate 20 finally causes the second elastic telescopic rod 21 to elastically shorten; with the continuous downward movement of the net bag 10, when the net bag 10 moves to the bottommost end of the limiting groove 25-1, correspondingly, the extrusion block 23 at the upper end of the second rack 22 moves to the position of the extrusion driving part 33-1, and the extrusion driving part 33-1 moves downward until the limiting rod 33 loses the limiting effect on the free end of the second elastic telescopic rod 21; when the limit rod 33 loses a moment of limit; the second elastic expansion link 21 moves leftwards under the action of the elastic force in the second elastic expansion link, so that the prepared net bag 10 is pushed to rapidly enter a station; then the saturated tuck net 10 at the bottom end of the limiting groove 25-1 is manually dismounted, after the tuck net 10 is taken out, because the saturated tuck net 10 does not extrude the limiting ejector rod 13 downwards any more, the connecting plate 20 resets under the action of the return spring 11, so that the first rack 14 is driven to reset, the ejector rod 13 is further driven to reset to return to the initial position again, and the tuck net 10 which crosses the damping section 29 is prepared to be caught. Thus, one complete switching can be completed.
The intercepting net replacing device judges the saturation degree of the net bag 10 by using the water pressure, and the force is stored for replacing the intercepting net through the movement of the net bag 10 on the path, so that the effect of automatically replacing the net bag 10 can be achieved; on one hand, the automation degree is improved, and the efficiency of replacing the interception net is improved; on the other hand, the replacing device does not need to be stopped, and does not need to seal a branch pipeline, so that the water hammer effect caused by severe pipe pressure change can be effectively prevented, and the pipeline can be protected.
The device also comprises an arc blocking 2-1 which is used for preventing water flow from sputtering and slides on the inner wall of the distribution pipe 2, wherein the arc blocking 2-1 falls and is blocked by means of gravity, so that the water flow is prevented from overflowing from a slide way of the net bag 10, the slide way is prevented from being blocked by sundries, secondly, the arc blocking 2-1 is jacked up when the net bag 10 enters a station through a wedge surface of the arc blocking 2-1, and the arc blocking 2-1 is prevented from blocking the falling position of the net bag 10.
Further: the lower end of the limiting groove 25-1 is provided with a transfer device for transferring the saturated net bag 10; the transfer device comprises a one-way rotating shaft 15 which is rotatably arranged on the inner wall of the shell 5, and a shifting fork 12 is arranged on the rotating shaft at equal angles; a guide rail 24 which is used for transferring the saturated tuck net 10 and is fixed with the shell 5 is arranged between the shifting forks 12 at the two sides, and a drainage plate 27 which is fixed with the shell 5 and is used for extruding the tuck net 10 is arranged at the lower end of the guide rail 24; the upper end of the shell 5 is provided with a split shell 5-1 for separating the distribution pipes 2; a net outlet 5-2 for discharging the net bag 10 is arranged on the inner wall of the split shell 5-1 corresponding to the tail end of the guide rail 24; the transfer device further comprises a pushing unit for pushing the saturated tuck net 10 to the path of the shifting fork 12; the end of the driving gear 17 is in transmission connection with the one-way rotating shaft 15 through a driving belt 16.
Because the saturated tuck net 10 contains more water among the sundries besides the sundries, different from fresh water, the seawater has stronger corrosivity and too much water content, and is not beneficial to the centralized treatment of the sundries in the back; meanwhile, the difficulty is high when the net bag 10 is manually taken down in a rapid stream.
When in use:
when the net bag 10 falls into the bottom end of the limiting groove 25-1, the net bag 10 is pushed to the motion path of the shifting fork 12 through the pushing unit; then when the push rod 13 is pressed down again after being reset, the driving gear 17 can drive the one-way rotating shaft 15 to rotate through the driving belt 16, so as to drive the shifting fork 12 to rotate anticlockwise (as shown in fig. 4); when the shifting fork 12 rotates, the net bag 10 is driven to move upwards along the guide rail 24, so that the net bag 10 is extruded and drained under the action of the drainage plate 27; it should be noted that the shift fork 12 only rotates in one direction under the action of the one-way rotating shaft 15; secondly, because the descending speed of the top rod 13 is slow (related to the proportion of impurities in water, but certainly slower than the resetting speed of the top rod 13), the net bag 10 has longer draining time on the drainage plate 27, thereby effectively draining water, and when the shifting fork 12 rotates for a certain angle, the net bag 10 can be discharged through the net outlet 5-2.
According to the invention, the shifting fork 12 is arranged, so that firstly, the shifting fork 12 can automatically rotate and increase the interception force of the net bag 10, and secondly, the shifting fork 12 can effectively increase the draining time of the net bag 10, so that the residual seawater of the saturated net bag 10 can be automatically removed; thereby further protecting external equipment, reducing the risk of corrosion and simplifying the subsequent sundries treatment steps.
And further: the pushing unit comprises a position-giving part 13-1 arranged at the upper end of the ejector rod 13 and a first elastic telescopic rod 19 fixedly arranged on a connecting plate 20; the free end part of the first elastic telescopic rod 19 is provided with a supporting block 30 which is elastically and rotatably arranged; the supporting block 30 can be attached to the side wall of the ejector rod 13 to limit the free end of the first elastic telescopic rod 19, and the supporting block 30 can slide through the abdicating part 13-1 to cancel the limit on the free end of the first elastic telescopic rod 19; the upper side of the free end of the first elastic telescopic rod 19 is elastically and rotatably provided with a second pushing block 31 for pushing the net bag 10 through a fixing block 26-1; the height difference between the lower side of the second pushing block 31 and the upper end of the supporting block 30 is greater than the height difference between the upper end of the positioning portion 13-1 and the upper surface of the mandril 13.
When in use:
in the descending process of the ejector rod 13, the first elastic telescopic rod 19 and the second elastic telescopic rod 21 both store power, and the first elastic telescopic rod 19 is limited by the supporting block 30 and the ejector rod 13; when the top rod 13 descends to a position-letting part 13-1 to be flush with the supporting block 30, the supporting block 30 passes over the top rod 13 under the action of the first elastic telescopic rod 19, so that the free end of the first elastic telescopic rod 19 is free, the second pushing block 31 passes over the upper end part of the top rod 13, the net bag 10 is pushed into the end part of the guide rail 24 through the limiting lug 10-1 of the net bag, and the net bag 10 enters the path of the shifting fork 12. When the supporting block 30 contacts the relief part 13-1, the mandril 13 cannot reset; when the push rod passes through the yielding part 13-1, the push rod 13 starts to reset; meanwhile, after the top rod 13 is completely reset, the first elastic telescopic rod 19 is reset, and because the top rod 13 can not limit the rightward movement of the second pushing block 31 and the supporting block 30 (the direction is as shown in fig. 4, the characteristics are combined with fig. 6, wherein the state of the supporting block 30 in fig. 6 is the extreme rotation angle state, the end part of the supporting block 30 can only rotate towards the direction of the first elastic telescopic rod 19); therefore, the first elastic telescopic rod 19 can be completely restored.
According to the invention, through the matching among the supporting block 30, the first elastic telescopic rod 19 and the second pushing block 31, the full-automatic non-stop replacement of a whole set of net bags 10 can be completed completely; in addition, no external power source is introduced in the replacement process of the net bag 10, so that the cost can be effectively controlled, and introduced electrical elements can be prevented from being corroded.
Further: the free end of the first elastic telescopic rod 19 is elastically and slidably provided with a wedge-shaped adjusting block 26 to adjust the position of the shifting fork 12.
Because the shifting fork 12 rotates by using the one-way bearing, and the transmission ratio of the one-way bearing is difficult to be accurate, the situation that the limiting lug 10-1 can directly impact the end part of the shifting fork 12 under few situations can be caused, and the shifting fork 12 is difficult to work stably all the time; in this section, the adjusting block 26 is designed to adjust the position of the shift fork 12, which may cause the collision between the end portion of the shift fork and the limiting lug 10-1, to a certain degree counterclockwise, thereby avoiding the collision between the shift fork and the limiting lug 10-1 (the end portion of the shift fork 12 and the adjusting block 26 have no collision, and the inclined surface of the adjusting block 26 is a dangerous area in practice).
And further: a collecting part 8 for collecting the saturated tuck net 10 is arranged between the sub-shells 5-1 (the collecting part 8 can be a transmission belt or a box body).
And further: the net bags 10 are longitudinally stacked at the end part of the mounting plate 18 through an external limiting mechanism, and the net bag 10 at the lowest part can be pushed into the lower end of the distribution pipe 2; the upper end of the second elastic telescopic rod 21 is elastically and rotatably provided with a first pushing block 28; the first pushing block 28 can pass over the lowermost string bag 10 by rotating when the return spring 11 is returned.
When in use, the horizontal degree of freedom of the net bag 10 can be limited through the frame body, so that only the net bag 10 at the lowest part has the degree of freedom of horizontal movement to the left; the first pusher block 28, like the second pusher block 31, can be actuated in only one direction; thereby effectively restoring the first pusher block 28.
Further: the lower end of the mounting frame 7 is provided with a roller 6 to facilitate the transfer of the equipment.
