Abstract
Description
Technical Field
[0001] This utility model relates to the field of interception grids, specifically an interception grid for water conservancy projects. Background Technology
[0002] Initially, bar screens were porous structures that could intercept debris floating on the water surface. With development, bar screens with transmission functions emerged, which could not only intercept debris but also lift it up and actively discharge it with the help of a conveyor belt.
[0003] In existing technologies, bar screens and conveyor belts are constantly running, resulting in high energy consumption. Utility Model Content
[0004] The purpose of this utility model is to provide an interception grid for water conservancy projects in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an intercepting screen for water conservancy projects, comprising a transmission screen machine, a fixing rod fixedly installed on the end plate of the transmission screen machine, the fixing rod extending to the back end of the transmission screen machine and having a receiving hopper installed thereon, a temporary storage box connected to the output end of the receiving hopper, a blocking mechanism extending to the output port of the temporary storage box being installed outside the temporary storage box, a driving mechanism for driving the blocking mechanism to move up and down being installed outside the temporary storage box, and a reset guide mechanism for moving the blocking mechanism being installed outside the temporary storage box.
[0006] As a further embodiment of this utility model: the reset guide mechanism includes two guide shafts fixedly installed outside the temporary storage box, and a sliding lug is slidably connected to the outer wall of the guide shaft. A spring abuts between the top end of the sliding lug and the top protrusion of the guide shaft.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-3 In this embodiment of the present invention, an intercepting screen for water conservancy projects includes a transmission screen machine 1. A fixing rod 2 is fixedly installed on the end plate of the transmission screen machine 1. The fixing rod 2 extends to the back end of the transmission screen machine 1 and is equipped with a receiving hopper 3. The output end of the receiving hopper 3 is connected to a temporary storage box 4. A blocking mechanism extending to the output port of the temporary storage box 4 is installed on the outside of the temporary storage box 4. A driving mechanism for driving the blocking mechanism to move up and down is installed on the outside of the temporary storage box 4. A reset guide mechanism for moving the blocking mechanism is also installed on the outside of the temporary storage box 4.
[0018] In this embodiment: When the transmission bar screen 1 is running, the debris floating on the water surface (such as branches, plastic bags, etc.) is pulled up by the transmission bar screen and transported to the back end. When the debris reaches the top of the back end of the transmission bar screen 1, it falls into the receiving hopper 3 under its own weight. Since the blocking mechanism is closed at this time, the debris accumulates in the temporary storage box 4 through the receiving hopper 3. After the debris accumulates to a certain amount, it needs to be discharged. At this time, the drive mechanism is started. During the operation, the drive mechanism pushes the blocking mechanism to move upward. After the blocking mechanism moves to the top, it falls again under the push of the reset guide mechanism, so as to realize the intermittent discharge of debris.
[0019] It should be noted that a V-shaped conveyor belt should be installed at the output end of the temporary storage box 4. The conveyor belt should be started before the drive mechanism, so that the intermittently discharged dirt can fall onto the V-shaped conveyor belt in an orderly manner and be output outward, avoiding the rapid outflow of dirt and the resulting scattering. It also avoids the problem of the V-shaped conveyor belt running for a long time.
[0020] Please refer to this carefully. Figure 2 and Figure 3 The reset guide mechanism includes two guide shafts 5 fixedly installed on the outside of the temporary storage box 4. A sliding lug 13 is slidably connected to the outer wall of the guide shaft 5. A spring 6 abuts between the top of the sliding lug 13 and the top protrusion of the guide shaft 5.
[0021] In this embodiment: During the operation of the drive mechanism, the drive mechanism pushes the blocking mechanism to move upward. During this process, the spring 6 is compressed. After the blocking mechanism moves to the top, the drive mechanism stops pushing the blocking mechanism. Then the reset spring 6 can push the blocking mechanism to reset downward.
[0022] During the above process, the upward-moving blocking mechanism no longer blocks the dirt in the temporary storage box 4, and the dirt is discharged outward along the temporary storage box 4. When the blocking mechanism resets downward, it blocks the dirt, thus realizing the intermittent discharge of dirt and avoiding the problem of scattering caused by the rapid outflow of dirt.
[0023] Please refer to this carefully. Figure 2 and Figure 3 The blocking mechanism includes a horizontal plate 7 fixedly connected to one end of two sliding ears 13. A connecting plate 8 that penetrates into the inner cavity of the output end of the temporary storage box 4 is fixedly installed at the bottom end of the horizontal plate 7. A blocking plate 9 with a porous structure is fixedly installed at the bottom end of the connecting plate 8.
[0024] In this embodiment: when the drive mechanism is running, the drive mechanism drives the horizontal plate 7 to move upward, the sliding lug 13 of the horizontal plate 7 moves along the guide shaft 5, and at the same time the horizontal plate 7 drives the connecting plate 8 to move synchronously, and the connecting plate 8 drives the blocking plate 9 to move. At this time, the blocking plate 9 no longer closes the output port of the temporary storage box 4.
[0025] When the blocking mechanism resets downwards, the blocking plate 9 closes the output port of the temporary storage box 4 again, thus achieving the purpose of intermittent discharge of waste.
[0026] The porous baffle plate 9 allows water mixed with pollutants to be discharged outwards.
[0027] Please refer to this carefully. Figure 2 and Figure 3 The drive mechanism includes a rotary motor 10 mounted on the outside of the temporary storage box 4 via a bracket. A rotating disk 11 is fixedly mounted on the output end of the rotary motor 10. An eccentric rod 12 is rotatably mounted on the end of the rotating disk 11 away from the rotary motor 10 at an eccentric position.
[0028] In this embodiment: When the rotary motor 10 is running, the eccentric rod 12 is driven to rotate by the rotating disk 11. During the upward rotation of the eccentric rod 12 from the lowest point, it applies a squeezing force to the bottom end of the horizontal plate 7. At this time, the horizontal plate 7 can move upward until the eccentric rod 12 rotates to the highest position and then rotates downward. The downward rotating eccentric rod 12 no longer applies a squeezing force to the bottom end of the horizontal plate 7. At this time, the spring 6 can push the blocking mechanism to reset.
[0029] Please refer to this carefully. Figure 3 The interior of the temporary storage box 4 has a strip groove for the connecting plate 8 to slide.
[0030] In this embodiment: the strip groove allows the connecting plate 8 and the blocking plate 9 to slide.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
