Description

Technical Field

[0001] The invention relates to the technical field of water conservancy drainage and drainage, and in particular to a drainage and drainage device for water conservancy projects. Background Art

[0002] For example, the Chinese patent with announcement number CN220978261U discloses a drainage device for water conservancy projects. When the device is in use, the pipeline may be blocked by impurities, resulting in failure to divert and drain water normally. The filter plate filters out impurities such as mud and sand in the water. If it cannot be cleaned quickly, the device will be blocked. It includes a drainage component, a first water diversion component, and a second water diversion component. Water is diverted by the first water diversion component and the second water diversion component to solve the problem that when the device is in use, the pipeline may be blocked by impurities, resulting in failure to divert and drain water normally.

[0003] However, the above scheme has the following shortcomings: in the above patent, the garbage is taken out of the canal through the storage box for cleaning, and then reinstalled into the canal after cleaning; when there are too many impurities on the filter screen, the filter screen is taken out of the canal for cleaning, and then reinstalled into the canal for use after cleaning, so as to solve the problem that the filter plate filters out impurities such as mud and sand in the water, and if it cannot be cleaned quickly, it will cause the device to be blocked. However, in actual use, this method also requires manual removal of the storage box and the filter screen from the canal, dumping the garbage in the storage box, and cleaning the filter screen before installing it back into the canal before drainage can be carried out again, which is more troublesome to operate. For this reason, we have introduced a new type of drainage device for water conservancy projects. Summary of the invention

The water source entering the drainage box 1 passes through the filter plate 2 and enters the drainage pipe 15. A lifting plate 5 is slidably connected to the drainage box 1, and one side of the lifting plate 5 is tightly connected to the inner side of the drainage box 1. The first side of the lifting plate 5 is tightly fitted with the filter plate 2, and the other side is tightly fitted with the filter plate 2, so that the lifting plate 5 can scrape the garbage on the surface of the filter plate 2 when it moves upward. The upper end of the lifting plate 5 is fixedly connected with the first traction rope 4, and the upper end of the first traction rope 4 extends out of the drainage box 1 and is fixedly connected with the wire-reeling mechanism. The first traction rope 4 is rolled up by the wire-reeling mechanism, so that the lifting plate 5 drives the garbage and debris on its upper end to move upward. The wire-reeling mechanism is movably sleeved on the outside of the connecting shaft 12, and the connecting shaft 12 is movably connected to the inside of the U-shaped plate 10. The U-shaped plate 10 is fixedly installed on the upper end of the drainage box 1, and two sets of square rings 22 are fixedly sleeved on the outside of the connecting shaft 12;

[0026] Two groups of push plates 3 are provided on the upper side of the lifting plate 5, and a gap is provided between the two groups of push plates 3 for the first traction rope 4 to pass through, so that when the wire-retracting mechanism drives the two groups of push plates 3 to move, they will not contact the first traction rope 4, resulting in the push plates 3 being unable to move. The two groups of push plates 3 are slidably connected in the storage cavity 33, and the storage cavity 33 is opened on the inner side of the drainage box 1. Two groups of second traction ropes 20 are fixedly connected to one side of the push plate 3. After the end of the second traction rope 20 away from the push plate 3 passes through the discharge port 32 and the positioning ring 19, it is connected to the wire-retracting mechanism. When the connecting shaft 12 rotates, the wire-retracting mechanism will drive the two groups of push plates 3 to disengage from the storage cavity 33, and push the garbage and debris on the upper end of the lifting plate 5 to move to the position of the discharge port 32, so that the garbage and debris are discharged into the external environment;

[0027] The positioning ring 19 is fixedly installed on the upper end of the drainage box 1, and the two sets of second traction ropes 20 are guided and positioned by the positioning ring 19. A discharge port 32 is opened in one side of the drainage box 1, and the garbage and debris on the upper end of the lifting plate 5 are discharged from the drainage box 1 through the discharge port 32. The outer side of the connecting shaft 12 is movably sleeved with a support ring 17, and the support ring 17 is fixedly connected to the side of the wire-taking mechanism with two sets of clamping rods 26. The clamping rods 26 are clamped in the clamping holes 25, and the clamping holes 25 are opened in the wire-taking mechanism. One end of the connecting shaft 12 is fixedly connected to the output end of the motor 13, and the motor 13 is fixedly installed A drain pipe 15 is fixedly installed at the upper end of the drainage box 1 and the lower end of the drainage box 1. A trigger mechanism is provided in the drain pipe 15. Sensors 9 are fixedly connected to the inner side of the drainage box 1 and one end of the lifting plate 5. The sensor 9 can be selected into a suitable model and size in actual use. When the sensor 9 located in the lifting plate 5 moves to the position of the sensor 9 inside the drainage box 1, the lifting plate 5 will stop moving. A certain gap will be left between the lifting plate 5 and the push plate 3. When the take-up wheel 11 on the right side moves to the left, the first traction rope 4 is pulled, and the lifting plate 5 contacts the push plate 3.

[0028] Embodiment 2:

[0029] On the basis of Example 1, in order to enable the first traction rope 4 and the second traction rope 20 to be separately wound up, the take-up mechanism includes two groups of take-up wheels 11, and a slip ring 23 is provided between the two groups of take-up wheels 11. Both ends of the slip ring 23 are movably connected to the corresponding take-up wheels 11. Through the setting of the slip ring 23, one group of take-up wheels 11 can drive the other group of take-up wheels 11 to move when moving. A connecting ring 24 is movably connected to one end of the left take-up wheel 11. The motor 13 is started and drives the connecting shaft 12 to rotate. Under the elastic force of the connecting spring 18, the take-up wheel 11 on the right side will be sleeved on the right side. The square ring 22 of the U-shaped plate 10 is on the outside of the square ring 22. At this time, during the rotation of the connecting shaft 12, the take-up wheel 11 on the right side will be driven to start rotating, so that the first traction rope 4 is wound up. After the first traction rope 4 is wound up, the lifting plate 5 will drive the garbage and debris to move upward. A connecting spring 18 is sleeved on the outside of the connecting shaft 12. One end of the connecting spring 18 is fixedly connected to the inner side of the U-shaped plate 10, and the other end is fixedly connected to the connecting ring 24. One end of the two sets of second traction ropes 20 away from the push plate 3 is fixedly connected to the take-up wheel 11 on the left side. One end of the first traction rope 4 away from the lifting plate 5 extends out of the drainage box 1 and is fixedly connected to the take-up wheel 11 on the right side.

[0030] A plurality of groups of snap-in holes 25 are provided in one end of the right take-up wheel 11 close to the support ring 17. When the sensor 9 in the lifting plate 5 moves to the position of the sensor 9 inside the drainage box 1, the motor 13 stops rotating, and the telescopic cylinder 16 starts to drive the support ring 17 to move to the left. The support ring 17 moves to the left and drives the two groups of snap-in rods 26 to snap into the corresponding snap-in holes 25, so that the take-up wheel 11 on the right is limited and cannot rotate. At the same time, the support ring 17 pushes the two groups of take-up wheels 11 to move, so that the take-up wheel 11 on the right is separated from the outside of the square ring 22 on the right, and the take-up wheel 11 on the left moves to the position of the square ring 22 on the left. At this time, the motor 13 restarts, and when the connecting shaft 12 rotates, the take-up wheel 11 on the right will not rotate with it, but the take-up wheel 11 on the left will rotate with it.

[0031] Two groups of T-shaped rods 8 are fixedly connected to the outside of the push plate 3. The T-shaped rods 8 are slidably connected to the T-shaped slots 21. The T-shaped slots 21 are opened on the inside of the drainage box 1. A reset spring 6 is fixedly connected to the T-shaped slots 21. The other end of the reset spring 6 is fixedly connected to the T-shaped rod 8. After the two groups of second traction ropes 20 are wound up, they will drive the corresponding push plates 3 to start moving. When the push plates 3 move, they drive the T-shaped rods 8 to slide along the T-shaped slots 21, so that the reset springs 6 are compressed. When the winding of the two groups of second traction ropes 20 is cancelled, the two groups of push plates 3 will return to their original positions under the elastic force of the reset springs 6.

[0032] A telescopic cylinder 16 is fixedly connected inside the U-shaped plate 10, and the output end of the telescopic cylinder 16 is fixedly connected to the support ring 17. A T-shaped guide rod 27 is fixedly connected inside the U-shaped plate 10, and one end of the T-shaped guide rod 27 is fixedly connected to the support ring 17. When the sensor 9 located in the lifting plate 5 moves to the position of the sensor 9 inside the drainage box 1, the motor 13 will stop rotating, and the telescopic cylinder 16 will start to drive the support ring 17 to move to the left. The support ring 17 moves to the left and drives the two sets of clamping rods 26 to be clamped into the corresponding clamping holes 25, so that The right side take-up wheel 11 is limited and cannot rotate, and the trigger mechanism includes a connecting plate 14, and two groups of T-shaped support rods 30 are fixedly connected to the upper end of the connecting plate 14. The T-shaped support rod 30 is slidably connected in a sliding cavity 31, and the sliding cavity 31 is opened in the drain pipe 15. A support spring 28 is sleeved on the outer side of the T-shaped support rod 30, and one end of the support spring 28 is fixedly connected to the sliding cavity 31, and the other end is fixedly connected to the T-shaped support rod 30. A press switch 29 is provided on the upper side of the T-shaped support rod 30, and the press switch 29 is fixedly installed in the upper end of the sliding cavity 31.

[0033] Working principle: when in use, connect the external water pipe to the input end of the water pump 7, turn on the water pump 7 to pump the water source to be drained into the drainage box 1, and the water source entering the drainage box 1 passes through the filter plate 2 and enters the drainage pipe 15. Since there is no accumulation of garbage and debris in the drainage box 1, the water source on the left side of the filter plate 2 will all pass through the filter plate 2 and enter the drainage pipe 15. Under the impact of the water flow, the connecting plate 14 located in the drainage pipe 15 will be driven to move downward, and the movement of the connecting plate 14 drives the two groups of T-shaped support rods 30 connected to its upper end to move downward, so that the support spring 28 is compressed, and at this time the T-shaped support rod 30 will cancel the pressing of the press switch 29;

[0034] When there is a lot of garbage and debris accumulated in the drainage box 1, the filter plate 2 will be blocked and the water flow entering the drainage pipe 15 will become smaller. When the impact force of the water flow is less than the elastic force of the support spring 28, the T-shaped support rod 30 will move upward and press the push switch 29 under the elastic force of the support spring 28. At this time, the water pump 7 will stop pumping water into the drainage box 1. At the same time, the motor 13 will start and drive the connecting shaft 12 to rotate. Under the elastic force of the connecting spring 18, the right side take-up wheel 11 will be sleeved on the outside of the right side square ring 22. At this time, during the rotation of the connecting shaft 12, the right side take-up wheel 11 will be driven to start rotating, so that the first traction rope 4 is wound. After the first traction rope 4 is wound, the lifting plate 5 will drive the garbage and debris to move upward. When the sensor 9 located in the lifting plate 5 moves to the position of the sensor 9 inside the drainage box 1, the motor 13 will stop rotating, and the telescopic cylinder 16 will start to drive the support ring 17 to move to the left.

[0035] The support ring 17 moves to the left and drives the two groups of clamping rods 26 to be clamped into the corresponding clamping holes 25, so that the right-side take-up wheel 11 is limited and cannot rotate. At the same time, the support ring 17 will push the two groups of take-up wheels 11 to move, so that the right-side take-up wheel 11 is disengaged from the outside of the right square ring 22, and the left-side take-up wheel 11 moves to the position of the left square ring 22. At this time, the motor 13 will restart, and when the connecting shaft 12 rotates, the right-side take-up wheel 11 will not rotate with it, while the left-side take-up wheel 11 will rotate with it. When the take-up wheel 11 rotates, the two groups of second traction ropes 20 are reeled in. At this time, the two groups of push plates 3 will be disengaged from the storage chamber 33, and push the garbage and debris on the upper end of the lifting plate 5 to move to the position of the discharge port 32, so that the garbage and debris are discharged into the external environment;

[0036] When the discharge is completed, the motor 13 will drive the connecting shaft 12 to rotate in the opposite direction, so that the left take-up wheel 11 will stop rewinding the second traction rope 20. Under the elastic force of the reset spring 6, the two sets of push plates 3 will be retracted into the storage chamber 33. At this time, the telescopic cylinder 16 will drive the push plates 3 to move right back to their initial position. Under the elastic force of the connecting spring 18, the right take-up wheel 11 will move back to the position of the square ring 22 on the right. At this time, the motor 13 controls the connecting shaft 12 to rotate in the opposite direction to return the lifting plate 5 to its original position.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
