Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1:
as shown in fig. 1, 2 and 3, the invention discloses a vertical pipeline pump capable of preventing blockage, which comprises a pipeline pump body 1, wherein input pipelines 11 and output pipelines 12 are arranged at two ends of the pipeline pump body 1, a driving motor 2 is arranged on the top surface of the pipeline pump body 1 through a bearing seat 21, and the pipeline pump body 1 is connected with an automatic blockage preventing mechanism 3 through the input pipelines 11;
it should be noted that, when the driving motor 2 is opened, the driving motor 2 can drive the impeller inside the pipeline pump body 1 to rotate through the output shaft, the rotating impeller can make the pipeline pump body 1 generate suction, that is, the liquid in the input pipeline 11 can be conveyed to the output pipeline 12 through the pipeline pump body 1, and the automatic anti-blocking mechanism 3 connected with the input pipeline 11 is used for removing foreign matters in the liquid, so that the working efficiency of the pipeline pump body 1 is not affected;
as shown in fig. 3, the automatic anti-blocking mechanism 3 comprises a mechanism main body 31, two ends of the mechanism main body 31 are fixedly connected with butt flanges 32, a sliding filter screen 33 is arranged in the mechanism main body 31, a limit rail 34 is arranged on the top surface of the mechanism main body 31, a scraper 36 is arranged in the limit rail 34, a pollution discharge roller 37 is arranged at the bottom of the mechanism main body 31 corresponding to the position of the scraper 36, the filter screen 33 judges the amount of net surface blocking according to the received resistance, and after the received resistance of the filter screen 33 reaches a set value, the scraper 36 is controlled to scrape the surface of the filter screen 33;
specifically, the mechanism main body 31 is in sealing connection with the input pipeline 11 through the butt flange 32 at one end, the mechanism main body 31 is in sealing connection with the liquid supply pipeline through the butt flange 32 at the other end, so that liquid can enter the pipeline pump body 1 through the liquid supply pipeline, the mechanism main body 31 and the input pipeline 11 and finally be output through the output pipeline 12, and the filter screen 33 arranged in the mechanism main body 31 can filter the liquid entering the mechanism main body 31, so that the liquid entering the pipeline pump body 1 is ensured to contain no foreign matters;
because the filter screen 33 is slidable, when liquid enters the pipeline pump body 1 from the liquid supply pipeline, the mechanism main body 31 and the input pipeline 11, the filter screen 33 is necessarily subjected to the resistance action of the liquid, and if the more foreign matters are intercepted on the surface of the filter screen 33, the more the resistance is, the amount of net surface plugs can be judged according to the resistance of the filter screen 33, in actual operation, the threshold value of the resistance of the filter screen 33 is preset, when the resistance of the filter screen 33 reaches the threshold value, the scraper 36 can be started to scrape the surface of the filter screen 33, the foreign matters on the surface of the filter screen 33 are removed, and the mechanism main body 31 can normally filter the liquid;
it should be emphasized that, the magnitude of the threshold value of the resistance to be applied to the filter screen 33 is very important in the operation of the automatic anti-blocking mechanism 3, because the threshold value is set too small, the filter screen 33 is caused to frequently start the scraper 36 to scrape the surface of the filter screen 33, the high-frequency operation of the scraper 36 can increase the loss of the scraper 36, thus the service life of the scraper 36 is reduced, while when the threshold value is set large, the filter screen 33 can intercept more foreign matters, the filter screen 33 cannot start the scraper 36, and the trafficability of the filter screen 33 is affected by the more foreign matters accumulated on the surface of the filter screen 33, so that the working efficiency of the pipeline pump body 1 is indirectly affected, therefore, the threshold value of the resistance to be applied to the filter screen 33 needs to be tested for a limited number of times, and the specific measurement method is as follows:
the first step, the driving motor 2 is turned on to enable the pipeline pump body 1 to normally carry out the work of transporting liquid, and then the foreign matter amount is gradually increased into the automatic anti-blocking mechanism 3;
secondly, as the amount of foreign matter intercepted by the filter screen 33 increases, the resistance of the filter screen 33 increases on one hand, and the trafficability decreases on the other hand;
thirdly, installing a flowmeter on the output pipeline 12, monitoring the working efficiency of the pipeline pump body 1, installing a force sensor in the mechanism main body 31, and monitoring the resistance change of the filter screen 33;
fourth, when the working efficiency of the pipeline pump body 1 is reduced, the flow meter mounted on the output pipeline 12 monitors the working efficiency of the pipeline pump body 1, and the force sensor in the mechanism main body 31 reads the resistance of the filter screen 33 at the moment, wherein the resistance is the threshold value of the resistance of the filter screen 33, and in order to ensure the working efficiency of the pipeline pump body 1, the threshold value of the resistance of the filter screen 33 can be adjusted by 5% -10% downwards in practice.
Example 2:
as shown in fig. 4, 5 and 6, an air pressure cavity 311 is formed in the mechanism main body 31, one side, close to the air pressure cavity 311, of the filter screen 33 is connected with a moving plate 331 through a long rod, and the moving plate 331 is matched with the air pressure cavity 311;
it should be noted that, the moving plate 331 divides the air pressure cavity 311 into two cavities, the end face of the air pressure cavity 311 near the scraper 36 is provided with a through hole (shown in fig. 5), the through hole is directly communicated with the external environment, when the scraper 36 pushes the moving plate 331, taking fig. 6 as an example, the through hole balances the air pressure in the cavity on the right side of the air pressure cavity 311, so that the air pressure cavity 331 is guaranteed not to receive the reaction force of the air pressure, and the cavity on the right side of the air pressure cavity 311 is a sealed cavity, so that in the process of moving the moving plate 331 to the left, the moving plate 331 gradually presses the cavity on the right side of the air pressure cavity 311, the air pressure in the cavity on the right side of the air pressure cavity 311 is increased, and the air pressure also acts on the side of the moving plate 331, and the moving plate 331 can act on the scraper 36 through a long rod, so that the scraper 36 can counteract the resistance in the mechanism main body 31.
Example 3:
as shown in fig. 6, an adjusting plate 315 matched with the air pressure cavity 311 is further arranged at the inner side of the air pressure cavity 311, a hydraulic cylinder 316 is arranged at one side of the adjusting plate 315 far away from the moving plate 331, and the output displacement of the hydraulic cylinder 316 is in direct proportion to the rotating speed of the driving motor 2, namely the power of the vertical pipeline pump;
in the actual use process of the vertical tube pump, the vertical tube pump adjusts the power of the vertical tube pump according to the situation of the site, that is, the power of the vertical tube pump is changed, when the power of the vertical tube pump is increased, the flow rate of the vertical tube pump is increased, and the resistance of the scraper 36 in the mechanism main body 31 is increased, so that the threshold value of the resistance of the scraper 36 needs to be correspondingly increased, which is specifically as follows:
the first step, dividing the power of the vertical pipeline pump into P1 and P2 … … Pn from low to high;
and a second step of: the threshold values F1, F2 … … Fn of the resistance force received by the filter screen 33 corresponding to the powers P1, P2 … … Pn were measured by the method of measuring the threshold value of the resistance force received by the filter screen 33 in example 1;
and a third step of: controlling the output displacement of the hydraulic cylinder 316, and when the resistance threshold values F1 and F2 … … Fn received by the maximum displacement of the filter screen 33 are recorded, controlling the corresponding displacement L1 and L2 … … Ln of the output of the hydraulic cylinder 316;
by the method, the output displacement of the hydraulic cylinder 316 can be adjusted according to the power of the vertical pipeline pump, so that the resistance threshold value received by the filter screen 33 can be indirectly adjusted, and the resistance threshold value received by the filter screen 33 is ensured to be matched with the actual work of the vertical pipeline pump.
Example 4:
as shown in fig. 5 and 6, the top surface of the limit rail 34 is fixedly connected with a power motor 35, an output shaft of the power motor 35 is fixedly connected with a screw rod 351, a ball nut 361 matched with the screw rod 351 is fixedly connected to the position of the top surface of the scraper 36 close to the screw rod 351, a butt-joint terminal 332 is fixedly connected to the middle position of the inner wall of the air pressure cavity 311, and the butt-joint terminal 332 is used for controlling the on-off of the power motor 35;
it should be noted that, when the moving plate 331 moves to the position of the butt-joint terminal 332, that is, the resistance of the filter screen 33 reaches the preset resistance threshold, a conductor piece is arranged at the position of the side surface of the moving plate 331 close to the butt-joint terminal 332, the conductor piece is connected with two butt-joint terminals 332, that is, a starting circuit of the power motor 35, when the starting circuit of the power motor 35 is connected, the power motor 35 rotates, because an output shaft of the power motor 35 is fixedly connected with the lead screw 351, the power motor 35 directly drives the lead screw 351 to rotate, and because the position of the top surface of the scraper 36 close to the lead screw 351 is fixedly connected with a ball nut 361 matched with the lead screw 351, the rotating lead screw 351 cooperates with the ball nut 361 of the top surface of the scraper 36, the scraper 36 can drive the scraper 36 to move downwards in the limit track 34, in the process of the downward movement of the scraper 36, the bottom surface of the scraper 36 scrapes the side surface of the filter screen 33, the foreign matters on the side surface of the filter screen 33 are pushed into the drain roller 37, automatic cleaning of the foreign matters on the side surface of the filter screen 33 is realized, when the scraper 36 scrapes the foreign matters on the side surface of the filter screen 33, and the power motor 35 is directly driven by the power motor 35 to rotate, the lead screw 351 is directly to rotate in the opposite direction to the side of the filter screen 33, and the opposite to the limit track 33 is disconnected, and the power motor 33 moves to the power 35 is completely, and the power plate 33 is disconnected when the side of the filter screen 33 is moved, and the power 35 is completely moves in the opposite to the side of the filter screen 33, and the side of the filter screen 33 is separated;
it should be emphasized that the side surface of the scraper 36 is hollowed out, so that the liquid in the mechanism main body 31 is not affected to pass through the filter screen 33 in the process that the scraper 36 moves up and down on the side surface of the moving plate 331.
The top of the limiting rail 34 is communicated with the inner cavity of the mechanism main body 31 through a pipeline, and it is to be noted that the top surface of the inner cavity of the limiting rail 34 is communicated with the inner cavity of the mechanism main body 31 through a pipeline, so that when the power motor 35 is opened to drive the scraper 36 through the cooperation of the screw rod 351 and the ball nut 361, liquid in the inner cavity of the mechanism main body 31 flows into the limiting rail 34 through the pipeline, namely the top end of the scraper 36, and thus the liquid pressure born by the top end of the scraper 36 and the liquid pressure born by the bottom end of the scraper 36 are mutually offset, and the scraper 36 is ensured to normally enter the inner cavity of the mechanism main body 31 to scrape the side surface of the moving plate 331.
Example 5:
as shown in fig. 7, a moving rail 312 matched with the filter screen 33 is provided in the mechanism main body 31 at a position close to the filter screen 33, a drain groove 313 is provided at a position close to the drain roller 37 on the bottom surface of the moving rail 312, and the drain groove 313 is engaged with the scraper 36;
it should be noted that, since the moving track 312 is matched with the filter screen 33, the filter screen 33 can slide freely along the axial direction of the butt flange 32 in the moving track 312, and the moving track 312 can limit the moving range of the filter screen 33, so that the filter screen 33 can slide stably within a certain range, and the stability of the filter screen 33 is ensured, and the dirt discharging groove 313 is matched with the scraper 36, so that when the scraper 36 slides down along the side surface of the filter screen 33, the scraper 36 can scrape all the foreign matters on the side surface of the filter screen 33 into the dirt discharging groove 313, thereby preventing the foreign matters from remaining in the mechanism main body 31, and ensuring the effect of the scraper 36 for removing the foreign matters on the side surface of the filter screen 33.
The bottom of the mechanism main body 31 is installed on the blow-down roller 37 through a rotating shaft, four sewage storage grooves are formed in the side face of the blow-down roller 37, a locking mechanism 38 is arranged in the mechanism main body 31 and close to the blow-down roller 37, and the sewage storage grooves are matched with the sewage discharge grooves 313.
It should be noted that, since the dirt storage tank is matched with the dirt discharge tank 313, the foreign matter entering the dirt discharge tank 313 will finally enter the dirt storage tank formed on the side surface of the dirt discharge roller 37 under the pushing of the scraper 36, and when the scraper 36 pushes the foreign matter into the dirt storage tank, the scraper 36 will also control the locking mechanism 38, so that the locking mechanism 38 releases the locking of the dirt discharge roller 37, and the dirt discharge roller 37 can be guaranteed to rotate ninety degrees clockwise, and a new dirt storage tank is replaced at the bottom of the dirt discharge tank 313, so that the dirt storage tank can receive the foreign matter again, as shown in fig. 8 and 9, and the process of discharging the foreign matter from the dirt storage tank is as follows:
firstly, foreign matters can enter a dirt storage tank at the top end position of the surface of the dirt discharging roller 37, after the scraper 36 controls the locking mechanism 38 to unlock the dirt discharging roller 37, the dirt discharging roller 37 can rotate under the action of the liquid pressure in the mechanism main body 31, clockwise rotation and anticlockwise rotation can be realized, as an example, fig. 9 is anticlockwise rotation, and in addition, note that the dirt discharging roller 37 is arranged at the bottom of the mechanism main body 31 through a rotating shaft, the friction force between the rotating shaft and the mechanism main body 31 is controlled, so that the rotation speed of the dirt discharging roller 37 is less than 10s/r, namely, when the dirt discharging roller 37 rotates for 90 degrees, the required time is at least 2.5s, here, taking 2.5s as an example, and the scraper 36 is required to be ensured to be separated from the locking mechanism 38 in the 2.5s, and when the dirt discharging roller 37 passes through 2.5s and then rotates anticlockwise by 90 degrees, the dirt storage tank at the side position of the dirt discharging roller 37 can be locked again by the locking mechanism 38;
when the scraper 36 pushes the foreign matters into the dirt storage groove at the top end position of the surface of the dirt discharging roller 37 again, as shown in fig. 10, after the locking mechanism 38 at this time releases the locking of the dirt discharging roller 37, the dirt discharging roller 37 must rotate anticlockwise due to the fact that the gravity on the left side of the dirt discharging roller 37 is greater than the gravity on the right side of the dirt discharging roller 37, so that the dirt discharging roller 37 can rotate 90 degrees again, and as shown in fig. 11, the dirt storage groove at the bottom of the dirt discharging roller 37 can automatically discharge the foreign matters under the action of gravity, so that the continuous automatic foreign matters discharge can be circulated under the automatic rotation of the dirt discharging roller 37, and the continuous operation of the automatic anti-blocking mechanism 3 is ensured.
As shown in fig. 9 and 12, the locking mechanism 38 includes a driving lock tongue 381, a first oil cavity 382 matching with the driving lock tongue 381 is provided in the interior of the mechanism main body 31 near the driving lock tongue 381, the driving lock tongue 381 is provided on the side wall of the drain groove 313, the first oil cavity 382 is connected with two second oil cavities 385 through an oil pipe 383, the interior of the two second oil cavities 385 is provided with a moving piston 386, the two moving pistons 386 are connected with a locking lock tongue 384 through a long rod, and the two locking lock tongues 384 are symmetrically provided on the side surface of the drain roller 37 and are used for being clamped on the drain groove on the side surface of the drain roller 37;
it should be noted that, a transverse spring is disposed in the first oil cavity 382, two locking bolts 384 are clamped on the inner wall of the pollution discharge groove aligned with the side surface of the pollution discharge roller 37, when the scraper 36 moves down to enter the pollution discharge groove 313, the scraper 36 extrudes the driving bolts 381, the driving bolts 381 extruded by the scraper 36 extrudes the hydraulic oil in the first oil cavity 382 against the elastic force of the spring, the hydraulic oil in the first oil cavity 382 enters the second oil cavity 385 through the oil pipe 383, the hydraulic oil entering the second oil cavity 385 pushes the movable piston 386 to move, the movable piston 386 drives one end of the locking bolts 384 away from the pollution discharge roller 37 to move, so that the locking bolts 384 are separated from the inner wall of the pollution discharge groove, and the locking of the pollution discharge roller 37 is released;
when the scraper 36 moves upwards to move out of the dirt discharging groove 313, the scraper 36 is separated from the driving lock tongue 381, the driving lock tongue 381 moves towards one end of the outer side of the first oil cavity 382 under the action of spring force, hydraulic oil in the second oil cavity 385 is pumped through the oil pipe 383, and at the moment, the moving piston 386 drives the locking lock tongue 384 to move towards one end close to the dirt discharging roller 37, so that the locking lock tongue 384 can be clamped on the inner wall of the dirt discharging groove again.
The foregoing describes one embodiment of the present invention in detail, but the description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
