Description

Technical Field

[0001] The present invention relates to the field of water conservancy projects, and more specifically, to a trash interception device for water gates in water conservancy projects. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature to achieve the purpose of eliminating disasters and bringing benefits. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, water gates, intakes, channels, aqueducts, raft channels, fishways, etc. to achieve their goals. A flood control dam is one of the water conservancy projects used to intercept floods to prevent soil erosion and ecological damage downstream.

[0003] All water conservancy projects are equipped with waterproof gates to achieve the purposes of flood control and irrigation. Since the waterproof gate is the only way for water to flow into the downstream, a large amount of trash often accumulates here. After the trash accumulates, it will block the valve, resulting in unsmooth drainage of the valve, and it will also pollute the downstream. Currently, the trash at the gate is generally collected through a filter net, and then the collected trash is fished out manually.

[0004] Chinese Patent with the authorization announcement number CN113774870B discloses a trash interception device for water gates in water conservancy projects. Through the water wheel drive mechanism, when the gate discharges water, the driving force for the runner to fish can be provided by the impact force of the water flow. This not only reduces the cost of trash fishing, but also can automatically adjust the rotation speed according to the size of the water flow to ensure the flexibility of trash fishing; the arc-shaped plate on the second shaft can quickly cut into the water, reducing the resistance of the water, and can maximize the conversion of the energy of the water into driving force; and through belt transmission, the first shaft and the second shaft can rotate in the same direction, and the trash in the water can be dialed onto the conveyor belt to avoid waste of energy.

[0005] In view of the above problems, the existing patent gives a solution, but the fishing depth is fixed. When installing the interception mechanism for different gates, it is necessary to produce interception mechanisms of different specifications, which leads to poor adaptability of the interception mechanism, and increases the production difficulty and production cost.

[0006] Therefore, a trash interception device for water gates in water conservancy projects is proposed. Summary of the Invention

[0013] Further, the guiding block is inclined and installed inside the collecting cylinder, one end of the conveyor belt is located below the discharge hole, and the collecting box is located below one end of the conveyor belt.

[0014] Further, the water control mechanism includes a fixing frame fixed on the surface of the top of the collecting box, an electric telescopic rod is fixedly installed at the bottom of the middle part of the fixing frame, the output end of the electric telescopic rod is rotatably connected with a rotating part, a torsion spring is fixedly installed on one side of the rotating part, and an extrusion plate is fixedly installed at the bottom of the rotating part.

[0015] Further, the detection mechanism includes a first detection plate fixed to the surface of the lock body.

[0018] Further, the bottom of the collection box is fixedly connected to the surface of the top of the second detection plate. One end of the top of the second pushing spring is fixedly connected to the surface of the second detection plate. The first trigger switch is located below the second detection plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] (1) In this solution, through the interception mechanism, the rotating filter shell and the filter plate intercept and salvage the floating objects on the water surface and the suspended substances in the water, so that the cleaning effect of the garbage can be improved more thoroughly. And a leak-proof plate is arranged at one end of the filter plate, so that after the garbage is intercepted and salvaged, the garbage can follow the filter plate and the filter shell to rotate at a specified angle, so that the problem of garbage falling during rotation can be avoided. And the filter plate can also extend or shorten inside the filter shell, so that it can be adjusted adaptively according to different lock bodies, and then the effect of meeting the use of locks of different specifications can be achieved.

[0021] (2) In this solution, through the cleaning mechanism, when the filter shell and the filter plate rotate to the top of the transmission cylinder, the extrusion block will squeeze the reciprocating block, and then the reciprocating block can drive the positioning plate and the positioning groove to no longer be engaged. Then, under the action of the counterweight, the filter plate moves downward and collides with the filter shell. The vibration generated by the collision causes the garbage to fall, which can increase the falling speed of the garbage and also avoid the problem that some garbage adheres to the surfaces of the filter shell and the filter plate, resulting in blockage of the filter shell and the filter plate and inconvenience in cleaning.

[0022] (3) With the collection mechanism in this solution, a collection cylinder is installed below the filter housing and the filter plate. As a result, the garbage inside the filter housing and the filter plate can enter the interior of the collection cylinder through the feed inlet. Then, the guide block guides the garbage, causing it to move in the direction of the conveyor belt. Subsequently, the conveyor belt can transport the garbage into the collection bin, thus completing the automatic collection of the garbage and reducing the labor intensity of the staff.

[0023] (4) With the water control mechanism in this solution, the electric telescopic rod drives the extrusion plate to move. Consequently, the extrusion plate can squeeze the garbage inside the collection bin, thereby squeezing out the water inside the garbage. The water then drains out through the drain holes, thus completing the cleaning of the water inside the garbage and avoiding the problem that a large amount of water absorbed by the garbage makes it inconvenient to handle the garbage.

[0024] (5) With the detection mechanism in this solution, when the garbage inside the collection bin increases, the weight of the collection bin becomes greater. As a result, the collection bin presses down on the second detection plate, causing the second detection plate to move downward and contact the first trigger switch. The first trigger switch then controls the electric telescopic rod to drive the extrusion plate to move, thereby completing the quantitative extrusion of the garbage and avoiding the existing problem of manual control of extrusion.

[0025] (6) With the alarm mechanism in this solution, when the collection bin is full of garbage, when the electric telescopic rod drives the extrusion plate to squeeze the garbage, it cannot continue to squeeze downward. As a result, the electric telescopic rod squeezes upward on the third push spring, causing the third push spring to contract. Subsequently, the electric telescopic rod contacts the second trigger switch, and the second trigger switch controls the alarm to sound, enabling the reminder of the staff to promptly handle the garbage.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0039] Please refer toFigures 1 to 10 , a trash interception device for a water conservancy project sluice, comprising a sluice main body 1, a driving mechanism 2 is fixedly installed on one side of the sluice main body 1, a first transmission rod 3 is fixedly installed on one side of the driving mechanism 2, a first transmission wheel 4 is fixedly installed at one end of the first transmission rod 3, a transmission belt 5 is sleeved on the surface of the first transmission wheel 4, an interception mechanism 6 is fixedly installed on one side of the sluice main body 1, and a water control mechanism 7 is fixedly installed on one side of the sluice main body 1.

[0040] The driving mechanism 2 adopts the prior art, which is a water wheel driving mechanism named in the patent with the authorization announcement number CN113774870B, and uses water flow to achieve the purpose of rotating the first transmission wheel 4.

[0041] As Figures 1 - 3 shown, the interception mechanism 6 includes a mounting frame 61 fixed on the surface of the sluice main body 1, a rotating cylinder 62 is rotatably connected inside the mounting frame 61, a connecting rod 63 is fixedly installed on the surface of one end of the rotating cylinder 62 inside the mounting frame 61, a transmission cylinder 64 is fixedly installed at one end of the connecting rod 63, a filter housing 65 is fixedly installed on the surface of the transmission cylinder 64, a filter plate 66 is slidably connected to the inner surface of the filter housing 65, a leak-proof plate 67 is fixedly installed at one end of the filter plate 66, a counterweight 68 is fixedly installed on the surface of one end of the leak-proof plate 67, a cleaning mechanism 69 is fixedly installed on the surface of one side of the filter housing 65, and a second transmission wheel 610 is fixedly installed at one end of the rotating cylinder 62.

[0042] In view of the problems existing in the actual use process, the prior art still has limited installation space and a relatively large salvage structure, resulting in a relatively high production cost of the salvage equipment.

[0043] In the present invention, by setting the interception mechanism 6, when it is necessary to salvage floating objects and suspended substances, the driving mechanism 2 drives the first transmission rod 3 and the first transmission wheel 4 to rotate. The rotation of the first transmission wheel 4 drives the transmission belt 5 to rotate. The rotation of the transmission belt 5 drives the second transmission wheel 610 to rotate. The rotation of the second transmission wheel 610 drives the rotating cylinder 62 to rotate. The rotation of the rotating cylinder 62 drives the connecting rod 63 and the transmission cylinder 64 to rotate, and then can drive the filter housing 65 and the filter plate 66 to rotate, so that the filter housing 65 and the filter plate 66 intercept foreign objects by salvaging.

[0044] As Figure 1 , Figure 5As shown, the cleaning mechanism 69 includes a limit frame 691 fixed to one side surface of the filter housing 65. A reciprocating block 692 is slidably connected inside the limit frame 691. A positioning plate 693 is fixedly installed on the surface of the reciprocating block 692 close to the filter housing 65. A positioning groove 694 is formed inside the filter plate 66 close to the positioning plate 693. A push plate 695 is fixedly installed on the surface of one side of the reciprocating block 692. A first push spring 696 is fixedly installed on the surface of the push plate 695. An extrusion block 697 is fixedly installed on the surface of the top of the mounting frame 61. A collection mechanism 698 is arranged on one side of the extrusion block 697.

[0045] In the actual use process, there is still a problem in the prior art that during the process of garbage salvage and interception, foreign objects will adhere to the surface of the salvage equipment, which will affect the subsequent salvage.

[0046] In the present invention, by setting the cleaning mechanism 69, when it is necessary to clean the garbage salvaged on the surfaces of the filter housing 65 and the filter plate 66, when the filter housing 65 and the filter plate 66 rotate, the reciprocating block 692 will be driven to rotate. When the reciprocating block 692 rotates to one side of the extrusion block 697, the extrusion block 697 will extrude the reciprocating block 692, and then the reciprocating block 692 will drive the positioning plate 693 to move. The movement of the positioning plate 693 will cause the positioning plate 693 to no longer be located inside the positioning groove 694. Furthermore, under the action of the counterweight block 68, the filter plate 66 can fall rapidly, and then the filter plate 66 and the filter housing 65 will collide, causing the filter plate 66 and the filter housing 65 to vibrate.

[0047] As Figures 3 - 5 As shown, the collection mechanism 698 includes a collection cylinder 6981 rotatably arranged inside the transmission cylinder 64. A feed inlet 6982 is formed on one side of the top of the collection cylinder 6981. A guiding block 6983 is fixedly installed at the bottom inside the collection cylinder 6981. An outlet hole 6984 is formed on one side of the collection cylinder 6981. A conveyor belt 6985 is fixedly connected to the surface of the water gate body 1 on one side of the outlet hole 6984. A collection box 6986 is arranged on one side of the conveyor belt 6985. A drain hole 6987 is formed inside the collection box 6986.

[0048] In the actual use process, there is still a problem in the prior art that it is inconvenient to collect the intercepted and salvaged garbage.

[0049] In the present invention, by providing a collection mechanism 698, when the filter housing 65 and the filter plate 66 vibrate, the garbage will fall downward, and then the garbage will enter the interior of the collection cylinder 6981 through the feed inlet 6982. Then, under the action of the guiding block 6983, the direction of the discharge hole 6984 of the garbage bin will be shifted, and then the conveyor belt 6985 is controlled to operate, so that the conveyor belt 6985 conveys the garbage falling from the discharge hole 6984 into the interior of the collection box 6986.

[0050] As Figures 1 - 5 shown, the guiding block 6983 is inclinedly installed inside the collection cylinder 6981. One end of the conveyor belt 6985 is located below the discharge hole 6984, and the collection box 6986 is located below one end of the conveyor belt 6985.

[0051] The top surface of the guiding block 6983 is an inclined surface, so that the garbage can move in the direction of the discharge hole 6984 under the action of the inclined surface.

[0052] As Figure 8 shown, the water control mechanism 7 includes a fixing frame 71 fixed to the top surface of the collection box 6986. At the bottom of the middle part of the fixing frame 71, an electric telescopic rod 72 is fixedly installed. The output end of the electric telescopic rod 72 is rotatably connected to a rotating member 73. One side of the rotating member 73 is fixedly installed with a torsion spring 74, and a pressing plate 75 is fixedly installed at the bottom of the rotating member 73. A limiting block 76 is fixedly installed on the inner surface of the fixing frame 71 and on one side of the middle part of the pressing plate 75, and a detection mechanism 77 is fixedly installed on one side of the fixing frame 71.

[0053] In the actual use process, in the prior art, there is still a large amount of water in the garbage, which will make the garbage heavier, resulting in inconvenient transportation and treatment of the garbage.

[0054] In the present invention, by providing the water control mechanism 7, when it is necessary to clean the water in the garbage in the collection box 6986, the control switch controls the output end of the electric telescopic rod 72 to move downward. The downward movement of the output end of the electric telescopic rod 72 will drive the pressing plate 75 to move downward. The downward movement of the pressing plate 75 will cause the limiting block 76 to no longer restrict the pressing plate 75. Then, under the action of the torsion spring 74, the pressing plate 75 is horizontally placed above the collection box 6986. Then, under the action of the electric telescopic rod 72, the pressing plate 75 squeezes the garbage in the collection box 6986, so that the water in the garbage flows out through the drain hole 6987, and thus the purpose of cleaning the water in the garbage can be achieved.

[0055] As Figure 7 and Figure 9As shown, the detection mechanism 77 includes a first detection plate 771 fixed to the surface of the sluice body 1. A L-shaped plate 772 is fixedly installed on the surface of one side of the first detection plate 771. A second push spring 773 is fixedly installed on the surface of the L-shaped plate 772, and a first trigger switch 774 is fixedly installed on the surface of the L-shaped plate 772. A second detection plate 775 is slidably connected to the surface of the L-shaped plate 772. An alarm mechanism 776 is fixedly installed at one end of the electric telescopic rod 72 close to the fixed frame 71.

[0056] When the second detection plate 775 contacts the first trigger switch 774, it will cause the electric telescopic rod 72 to complete a reciprocating motion.

[0057] In the actual use process, there is still a problem in the prior art that the water in the garbage cannot be quantitatively cleaned.

[0058] In the present invention, by setting the detection mechanism 77, when the garbage in the collection box 6986 becomes more and more, it will cause the garbage to press down the second detection plate 775, and then the second detection plate 775 will move downward. The downward movement of the second detection plate 775 will cause the second detection plate 775 to contact the first trigger switch 774, and then the output end of the electric telescopic rod 72 is controlled by the first trigger switch 774 to move, and then the garbage can be quantitatively dehydrated.

[0059] As Figure 10 As shown, the alarm mechanism 776 includes a trigger cylinder 7761 fixed to the inner surface of the fixed frame 71. A third push spring 7762 is fixedly installed inside the trigger cylinder 7761, and a second trigger switch 7763 is fixedly installed on the inner surface of the trigger cylinder 7761 and inside the third push spring 7762.

[0060] An alarm is installed on the sluice body 1, so that when the electric telescopic rod 72 contacts the second trigger switch 7763, the alarm will sound, so as to remind the staff.

[0061] In the actual use process, there is still a problem in the prior art that when the garbage in the collection box 6986 is full, an alarm cannot be issued in time to remind the staff to clean the garbage in time.

[0062] In the present invention, by providing an alarm mechanism 776, when the garbage inside the collection bin 6986 is full, when the electric telescopic rod 72 pushes the garbage, it cannot continue to push the garbage downward. As a result, the electric telescopic rod 72 moves upward, causing the electric telescopic rod 72 to squeeze the third pushing spring 7762. Consequently, the third pushing spring 7762 contracts, enabling the electric telescopic rod 72 to come into contact with the second trigger switch 7763. The second trigger switch 7763 controls the alarm to sound, reminding the staff to clean up the garbage.

[0063] As Figures 7 - 10 shown, the fixing frame 71 is U-shaped and is located on one side of the collection bin 6986. The surface of the extrusion plate 75 is slidably connected to the inner surface of the collection bin 6986.

[0064] As Figures 7 - 10 shown, the bottom of the collection bin 6986 is fixedly connected to the top surface of the second detection plate 775. One end of the top of the second pushing spring 773 is fixedly connected to the surface of the second detection plate 775. The first trigger switch 774 is located below the second detection plate 775.

[0065] The second detection plate 775 is connected to the L-shaped plate 772 through a convex block and a convex groove, enabling the second detection plate 775 to only move up and down and preventing it from falling off the surface of the L-shaped plate 772.

[0066] Usage method: Driven by the driving mechanism 2, the second transmission wheel 610 rotates, causing the second transmission wheel 610 to drive the transmission cylinder 64 to rotate. The transmission cylinder 64 drives the filter housing 65 and the filter plate 66 to rotate, intercepting and salvaging the garbage. When the filter housing 65 and the filter plate 66 drive the garbage to rotate above the transmission cylinder 64, the extrusion block 697 squeezes the reciprocating block 692, causing the positioning plate 693 and the positioning groove 694 to no longer be engaged. As a result, the filter plate 66 moves downward under the action of the counterweight 68, causing the filter plate 66 to collide with the filter housing 65, generating vibrations in the filter plate 66 and the filter housing 65. Consequently, the garbage on the filter plate 66 and the filter housing 65 falls off and enters the interior of the collection cylinder 6981 through the feed port 6982. Then, under the action of the guiding block 6983, it moves towards the conveyor belt 6985, and the conveyor belt 6985 drives the garbage into the interior of the collection bin 6986. Subsequently, the electric telescopic rod 72 drives the extrusion plate 75 to squeeze the garbage, causing the water in the garbage to drain through the drain hole 6987.

[0067] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
