An automatic sediment removal structure for water conservancy facilities in municipal engineering

Abstract

The present invention discloses an automatic sediment removal structure for water conservancy facilities in municipal engineering, relates to the technical field of sediment removal, and solves the problem that plastic bags are blocked outside by filter cages. Although the plastic bags can be prevented from clogging sediment pumps, the sediment needs to enter the sediment pump through the filter cage during sediment cleaning by the sediment pump. When there is a plastic bag blocking the filter cage, the sediment is difficult to enter the sediment pump and be discharged. The present invention comprises a sediment pump for extracting sediment deposited in a river channel, and a feed hopper is fixedly installed at the inlet end of the sediment pump. The present invention installs a cleaning component between a baffle and a conveying component, and a thorn rod in the cleaning component wraps the plastic bag around the outside of a casing and takes it away, so that the plastic bag blocked outside the baffle can be quickly cleaned to ensure the normal operation of the sediment pump. By installing an adjusting component in the casing, the thorn rod can be stored in the casing, which can effectively prevent workers from being accidentally injured by the thorn rod and barbs when cleaning the plastic bag on the casing.

Description

Technical Field

[0001] The invention relates to the technical field of sediment removal, in particular to an automatic sediment removal structure for water conservancy facilities in municipal engineering. Background Art

[0002] At present, with the large-scale construction of water conservancy and hydropower projects in my country, river siltation has become a prominent problem in its operation, maintenance and management. Due to the continuous increase in urban water diversion and irrigation water consumption, the upstream water volume has been continuously reduced, and the waste has been continuously increasing, resulting in continuous siltation of the river and the rise of the riverbed, which has reduced the original flood control and waterlogging resistance standards and water storage capacity of the river. Therefore, it is necessary to strengthen the management of the existing working conditions of the river;

[0003] The existing Chinese public patent 201911117421.1 discloses a sediment removal structure for water conservancy facilities. A filter cage is used to prevent plastic bags and other garbage from clogging the sediment pump. The sediment pump is started regularly at regular intervals to discharge the sediment accumulated on the diversion plane through a transport pipe to the water surface, preventing the sediment from accumulating on the diversion plane.

[0004] However, during the operation of the above device, the plastic bag is blocked outside by the filter cage. Although it can prevent the plastic bag from clogging the sediment pump, the sediment needs to pass through the filter cage to enter the sediment pump during the sediment cleaning process. When there is a plastic bag blocking the filter cage, the sediment is difficult to enter the sediment pump and be discharged. If the device is to operate normally, it is necessary to monitor in real time whether there is a plastic bag blocking the outside of the filter cage. If there is a plastic bag blocking it, the plastic bag needs to be removed immediately to ensure the normal operation of the device, which is inconvenient to use. Summary of the Invention

[0029] Example 1

[0031] See also Figure 6The cleaning component 6 includes a fixed base 601 fixedly mounted on the conveyor belt 504 by a plurality of sets of screws, and the plurality of sets of screws are distributed in a horizontal straight line. A sleeve 602 is installed on the fixed base 601, and two symmetrically distributed ball bearings 603 are fixedly mounted at the connection between the sleeve 602 and the fixed base 601, and the sleeve 602 is rotatably connected to the fixed base 601 through the ball bearings 603.

[0032] See also Figure 6 and Figure 8 Several groups of array-distributed thorn rods 604 are installed on the outside of the sleeve 602, and the ends of the thorn rods 604 are cone-shaped. The cone-shaped ends of the thorn rods 604 can penetrate into the interior of the circular tube 4. Two symmetrically distributed rubber rollers 605 are fixedly installed on the outside of the sleeve 602, and the rubber rollers 605 can roll on the left end of the baffle 3 after contacting the baffle 3. A first knob 606 is fixedly installed on the rear end of the sleeve 602, and several groups of equally distributed barbs 607 are fixedly welded on the upper and lower sides of the thorn rod 604.

[0033] See also Figure 7 The outer side of the sleeve 602 is provided with reserved through grooves 608, the number of which is equal to the number of the thorn rods 604, at the thorn rod 604, and the front end face of the reserved through groove 608 is an inclined end face. The thorn rod 604 is movably connected to the sleeve 602 through the reserved through groove 608, and the rear end of the thorn rod 604 is movably abutted with a top bead 609, and the top bead 609 is located in the reserved through groove 608 and fixedly welded to the sleeve 602.

[0034] See also Figure 1 The two transmission rollers 502 are rotatably connected to the mounting frame 501 through sealed bearings. One end of the transmission roller 502 located on the upper side is fixedly connected to the driving motor 503 through a coupling, and the driving motor 503 is fixedly connected to the mounting frame 501 through bolts.

[0035] See also Figure 5 A rotating shaft 8 is installed on the lower side of the conveyor belt 504 at the center of the lower end of the mounting frame 501, and the rotating shaft 8 is rotatably connected to the mounting frame 501 through a sealed bearing. Two symmetrically distributed cylindrical rods 10 are fixedly installed on the outer side of the rotating shaft 8, and a connecting component 9 is installed between the rotating shaft 8 and the transmission roller 502 located on the lower side.

[0036] See also Figure 5 The connecting component 9 includes a turbine 901 fixedly mounted on the lower end of the rotating shaft 8 and located inside the mounting frame 501. The outer side of the turbine 901 is located in the mounting frame 501 and is equipped with a worm 902 meshing with it. The front end of the worm 902 is fixedly welded with a connecting rod 903.

The outer sides of the two synchronous wheels 904 are sleeved with synchronous belts 905 meshing with them.

[0037] The working principle is convenient for cleaning the filtered plastic bags: when the sand pump 1 is running, the silt at the bottom of the river enters the hopper 2 from between the conveyor belt 504 and the baffle 3. When the silt contains plastic bags, the circular tube 4 installed on the baffle 3 filters the plastic bags out, and the driving motor 503 drives the transmission roller 502 on the upper side to rotate. Under the condition that the conveyor belt 504 is meshed with the transmission roller 502, the transmission roller 502 on the upper side drives the transmission roller 502 on the lower side to rotate through the conveyor belt 504, and the conveyor belt 504 transmits the cleaning component 6 to the baffle 3. After the rubber roller 605 in the cleaning component 6 contacts the baffle 3, the rubber roller 605 rotates while the cleaning component 6 continues to move. The rotation of the rubber roller 605 drives the sleeve 602 and several groups of thorn rods 604 to rotate together. Several groups of thorn rods 604 can pierce the plastic bags during the rotation. The plastic bag is passed into the circular tube 4. During the continuous rotation of the thorn rod 604, the barbs 607 on the outside of the thorn rod 604 can prevent the plastic bag from escaping from the thorn rod 604. Then, the rotation of the thorn rod 604 can wrap the plastic bag around the sleeve 602 and take it away, which is beneficial to keep the circular tube 4 unobstructed and ensure the normal operation of the sand pump 1. During the rotation of the transmission roller 502, the transmission roller 502 drives the connecting rod 903 and the worm 902 to rotate together through the synchronous wheel 904 and the synchronous belt 905. Under the condition that the turbine 901 is meshed with the worm 902, the rotation of the worm 902 drives the turbine 901 and the rotating shaft 8 to rotate, and the rotating shaft 8 drives the cylindrical rod 10 to rotate, which is beneficial to make the mud and sand deposited at the bottom of the mounting frame 501 flow and be discharged with the water flow, thereby preventing the bottom mud and sand from obstructing the cleaning assembly 6 when the cleaning assembly 6 moves to the bottom of the conveyor belt 504.

[0038] Example 2

[0039] See also Figure 6 、 Figure 7 and Figure 8 , this embodiment further explains Example 1, an adjustment component 7 is installed inside the sleeve 602, and the adjustment component 7 includes an adjustment rod 701 that is movably embedded in the sleeve 602 and can move back and forth inside the sleeve 602, and an articulated seat 702 equal to the number of the thorn rod 604 is fixedly installed on the outside of the adjustment rod 701, and a connecting shaft 703 passes through the thorn rod 604, and the thorn rod 604 is rotatably connected to the articulated seat 702 through the connecting shaft 703, and the front side of the thorn rod 604 is located between the thorn rod 604 and the adjustment rod 701, and an arc-shaped circular spring 704 equal to the number of the thorn rod 604 is installed.

[0040] See also Figure 7 and Figure 8The two ends of the arc-shaped circular spring 704 are respectively fixedly connected to the adjusting rod 701 and the thorn rod 604. The front end of the adjusting rod 701 is fixedly welded with a limiting sleeve 705. The limiting sleeve 705 is movably embedded with a limiting piece 706. The front end of the limiting piece 706 is fixedly welded with a screw 707. The screw 707 is rotatably connected to the limiting sleeve 705 through the limiting piece 706. The front end of the sleeve 602 is fixedly embedded with an internal threaded tube 709, and the connection between the screw 707 and the internal threaded tube 709 is a threaded connection. The front end of the screw 707 is located on the outside of the sleeve 602 and is fixedly connected to a second knob 708.

[0041] In this embodiment: when the conveyor belt 504 conveys the cleaning component 6 to the outside of the water surface and pauses, the staff member's left hand and right hand respectively pinch the first knob 606 and the second knob 708, and rotate the second knob 708 to rotate the screw rod 707. Under the condition that the screw rod 707 is rotatably connected with the limiting sleeve 705 through the limiting piece 706, the rotation of the screw rod 707 can move the adjusting rod 701 backward a certain distance through the limiting piece 706 and the limiting sleeve 705. In the process of the adjusting rod 701 moving backward, the top ball 609 pushes the thorn rod 604 to rotate forward. In the process of the adjusting rod 701 continuing to move backward, the thorn rod 604 can be completely retracted into the inside of the sleeve 602, so that the staff will not be accidentally injured by the thorn rod 604 and the barbs 607 on the thorn rod 604 when cleaning the plastic bag on the sleeve 602, and It can also increase the cleaning speed of plastic bags and improve cleaning efficiency. Although the thorn rod 604 can bring the distributed plastic bags into the sleeve 602, due to the ductility of the plastic bags, the staff can pull the plastic bags away from the thorn rod 604. After that, the staff will move the adjusting rod 701 forward a certain distance by rotating the screw 707 again. In the process of the adjusting rod 701 moving forward, the arc spring 704 drives the thorn rod 604 to rotate and reset. When the adjusting rod 701 moves to the top, since the front end face of the reserved through groove 608 is an inclined end face, the arc spring 704 is avoided to prevent the arc spring 704 from getting stuck. The thorn rod 604 is driven by the arc spring 704 to extend out from the reserved through groove 608 on the sleeve 602 again. Finally, the staff cleans up the plastic bag fragments remaining on the thorn rod 604.

[0042] Example 3

[0043] See also Figure 3 As with 4, this embodiment further illustrates other embodiments, where the left end of the circular tube 4 protrudes from the left end surface of the baffle 3.

[0044] In this embodiment, the circular tube 4 protrudes from the left end surface of the baffle 3, which can effectively prevent the plastic bag from fitting against the left end surface of the baffle 3, so that the thorn rod 604 can easily roll up the plastic bag and take it away.
