Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy garbage interception, and particularly relates to a water conservancy garbage interception device. 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, and are also called water projects. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet the needs of humans. Only by building water conservancy projects can the water flow be controlled, flood disasters be prevented, and the regulation and distribution of water volume be carried out to meet the needs of people's lives and production for water resources.

[0003] When floating garbage appears in the river channel, it is usually intercepted by a garbage interception device in the river channel.

[0004] A Chinese patent with the publication number of CN114150635B discloses a water-utilizing bridge-type garbage interception device, including: a bridge body and a descending mechanism, with a descending mechanism provided on the bridge body; a frame, with a frame provided on the descending mechanism; a stop block, with fourteen stop blocks rotatably provided on the frame; a pressing mechanism, with a pressing mechanism provided between the bridge body and the descending mechanism; a clamping mechanism, with a clamping mechanism provided at the bottom of the bridge body.

[0005] However, the above patent has the following problems: 1. In the above patent, the telescopic rod of the cylinder moves downward to drive the first slider to move downward, thereby driving the frame to move downward, and then driving the stop block to move downward, so that the stop block can intercept the garbage in the river channel. However, the cylinder and the sliding structure in the structure for driving the stop block in the above patent are both immersed in water without interception, resulting in garbage being easily blocked in these structures, thus causing the device to malfunction.

[0006] In the above patent, people pull the fourth slider outward to compress the seventh spring. When the fourth slider moves outward, people can use a nail to nail into the soil from the small hole in the fourth slider. However, the nail in the above patent is a smooth rod-shaped structure and cannot expand an additional fixing structure when the nail is inserted into the riverbed, thus reducing the fixing strength of the device. Summary of the Invention

[0007] The present invention provides a water conservancy garbage interception device, aiming to solve the problem that the cylinder and the sliding structure in the structure for driving the stop block in the above patent are both immersed in water without interception, resulting in garbage being easily blocked in these structures, thus causing the device to malfunction.

[0008] The present invention is implemented as follows. A water conservancy garbage blocking device includes a base. A mounting bin is fixedly connected to the top of the base. The number of the mounting bins is set to two, and the two mounting bins are symmetrically distributed about the center line of the base. A blocking door is provided between the two mounting bins. A lifting mechanism is provided between the blocking door and the two mounting bins, and the lifting mechanism is used to lift and adjust the blocking door. A fixing mechanism is provided on the surface of the base, and the fixing mechanism is used to plug and fix the device to the riverbed.

[0009] Preferably, the lifting mechanism includes a lifting structure and a driving structure. The number of the lifting structures is set to two, and the two lifting structures are respectively arranged inside the two mounting bins. The driving structure is used to drive the two lifting structures simultaneously.

[0010] Preferably, the lifting structure includes a through groove, a mounting plate and a guide wheel. The through groove penetrates through the side wall of the mounting bin. The mounting plate is arranged inside the mounting bin. Both sides of the mounting plate are fixedly connected to the inner wall of the mounting bin. The number of the mounting plates is set to two. A limiting rod is fixedly connected between the two mounting plates. A moving sleeve is sleeved on the outer periphery of the limiting rod. The moving sleeve is slidably connected to the limiting rod. A connecting rod is fixedly connected to the side wall of the moving sleeve. The middle part of the connecting rod penetrates through the through groove. The end of the connecting rod is fixedly connected to the blocking door. The guide wheel is arranged inside the mounting bin. Both ends of the guide wheel are rotatably connected to the inner wall of the mounting bin. The number of the guide wheels is set to two. A blocking belt is sleeved between the two guide wheels. The blocking belt is matched with the through groove. The middle part of the connecting rod penetrates through the blocking belt. Both sides of the blocking door are respectively fixedly connected to the two connecting rods. When the two connecting rods are both pulled upward, the blocking door can be driven to move upward, so that the blocking door can be opened. During this process, the connecting rod will drive the blocking belt penetrated by it to move synchronously, so that the blocking belt rotates between the two guide wheels, and the outer periphery of the blocking belt is always in contact with the through groove during rotation, so that external garbage can be prevented from entering the mounting bin through the through groove. Therefore, it can be avoided that the lifting structure is stuck due to garbage blockage during long-term use.

[0011] Preferably, the driving structure includes a connecting bin and a mounting frame. The connecting bin is arranged between the two mounting bins. Both ends of the connecting bin are fixedly connected to the two mounting bins respectively. Guide cylinders are respectively arranged through the connecting bin and the two mounting bins. A rotating rod is arranged inside the connecting bin. Both ends of the rotating rod are rotatably connected to the inner wall of the connecting bin. Two winding discs are fixedly connected to the outer periphery of the rotating rod. A first stepping motor is fixedly connected to the side wall of the connecting bin. The output shaft of the first stepping motor is fixedly connected to the rotating rod. The number of the installation frames is set to two. The two installation frames are respectively arranged in two installation bins. The side walls of the two installation frames are respectively fixedly connected with the inner walls of the two installation bins. Guide wheels are rotatably connected to the inner walls of the two installation frames. A traction rope is arranged between the winding disc and the connecting rod on the same side. One end of the traction rope is fixedly connected with the connecting rod, and the other end of the traction rope is fixedly connected with the winding disc. The middle part of the traction rope passes through the guiding cylinder, and the middle part of the traction rope is also arranged in a way that it is placed on the adjacent guide wheel. By starting the first stepping motor, the rotating rod can be driven to rotate forward. While the rotating rod rotates, the two winding discs can be driven to wind the two traction ropes respectively. Then, the two connecting rods can be pulled to move upward respectively through the two traction ropes. When the first stepping motor drives the rotating rod to rotate reversely, the two winding discs can be driven by the rotating rod to unwind the two traction ropes respectively. At this time, the two connecting rods are not under tension, so that the blocking doors connected by the two connecting rods move downward under the action of gravity, thus closing the blocking doors. And the driving structure is arranged at the top of the device and inside the connecting bin without contacting water. At the same time, a protective shell can be arranged on the outer periphery of the first stepping motor, so that the driving structure can avoid the reduction of the service life of the device caused by water immersion and the difficulty of maintenance.

[0012] Preferably, the fixing mechanism includes a first positioning groove and a fixing plate. The first positioning groove penetrates through the base, and the number of the first positioning grooves is set to be multiple. The fixing plate is arranged between the two installation bins. The two ends of the fixing plate are respectively fixedly connected with the two installation bins. The second positioning groove penetrates through the surface of the fixing plate, and the number of the second positioning grooves is set to be multiple. The multiple second positioning grooves are coaxially distributed with the multiple first positioning grooves respectively. A fixing cylinder penetrates through between the first positioning groove and the second positioning groove. The fixing cylinder is slidably connected with the first positioning groove and the second positioning groove. A fixing frame is fixedly connected above the fixing plate. The fixing frame is in the shape of an inverted "U". A second stepping motor is fixedly connected to the top of the fixing frame. The output shaft of the second stepping motor is fixedly connected with a threaded rod. The bottom of the threaded rod is rotatably connected with the fixing plate. A moving frame is threadedly connected to the outer periphery of the threaded rod. The bottom of the moving frame is fixedly connected with multiple fixing cylinders. A locking structure is arranged inside the fixing cylinder. By starting the second stepping motor, the threaded rod can be driven to rotate forward, and then the moving frame threadedly connected with it can be driven to move downward. At the same time, the moving frame will synchronously drive the multiple fixing cylinders to move downward, so that the bottom ends of the multiple fixing cylinders are inserted into the riverbed, and thus the device can be fixed.

[0013] Preferably, the locking structure includes a through groove, a sliding groove, a rotating column and a jack. The through groove penetrates through the side wall of the fixing cylinder. The sliding grooves are provided in multiple groups, and multiple groups of the sliding grooves are all formed on the outer periphery of the fixed cylinder, and the multiple groups of the sliding grooves are coaxially distributed; The number of each group of the sliding grooves is set to two, and insertion plates are slidably arranged inside the two sliding grooves, and limiting grooves are respectively formed through the surfaces of the two insertion plates; The rotating column is arranged inside the fixed cylinder, the top of the rotating column is rotationally connected with the top wall of the fixed cylinder, an extension rod is fixedly connected to the side wall of the rotating column, the middle of the extension rod penetrates through the through groove, a fixing bolt is fixedly connected to the end of the extension rod, a rotating disc is arranged below the rotating column, the bottom of the rotating disc is rotationally connected with the bottom wall of the fixed cylinder, two limiting shafts are fixedly connected between the rotating disc and the rotating column, the two limiting grooves respectively penetrate through a plurality of coaxially distributed limiting grooves, and the limiting shafts are movably connected with the limiting grooves; The jacks are formed on the surface of the moving frame, the number of the jacks is set to multiple, and the multiple jacks are respectively matched with the multiple fixing bolts; After the bottom end of the fixed cylinder is inserted into the riverbed, by pulling the extension rod, the rotating column can be driven to rotate. At the same time, the rotating column will drive the two limiting shafts to rotate. When the two limiting shafts rotate, they will respectively press the movably connected limiting grooves, thereby driving the insertion plates to move away from the center of the fixed cylinder in the sliding grooves, so that the insertion plates can be inserted into the soil of the riverbed, thereby increasing the fixing strength between the fixed cylinder and the riverbed. Finally, rotate the fixing bolt and insert the end of the fixing bolt into the corresponding jack, thereby fixing the extension rod.

[0014] Preferably, limiting frames are arranged on both sides of the through groove, and the side walls of the two limiting frames are fixedly connected with the inner wall of the installation bin; Limiting wheels are rotatably arranged on the inner circumference of the limiting frames, the number of the limiting wheels is set to multiple, and the multiple limiting wheels are evenly distributed; The two sides of the blocking belt can be respectively limited by the multiple limiting wheels on the surfaces of the two limiting frames, so as to prevent the blocking belt from elastically deforming due to water pressure and moving away from the through groove, thereby avoiding a large gap between the blocking belt and the through groove and causing garbage to enter the lifting structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By arranging the lifting mechanism, the lifting of the blocking door can be adjusted, so as to adjust the opening and closing of the blocking door. Moreover, the part of the lifting structure immersed in water can block garbage from entering the lifting structure and causing the lifting structure to get stuck. The driving part of the lifting structure is arranged at the top of the device and is not immersed in water and has a protection structure, which is beneficial to improving the service life of the lifting structure.

[0016] By setting the fixing mechanism, multiple fixing cylinders at the bottom of the device can be inserted into the riverbed, thereby improving the structural strength during the installation of the device. Moreover, multiple groups of insertion plates can be deployed on the outer periphery of the fixing cylinder and inserted into the riverbed, further enhancing the fixing strength of the fixing cylinder, which is conducive to improving the fixing strength of the fixing cylinder.

[0031] Working principle and usage process of the present invention: After the present invention is installed, by starting the first stepping motor 226, the rotating rod 224 can be driven to rotate forward. While the rotating rod 224 rotates, the two winding disks 225 can be driven to wind the two traction ropes 228 respectively, and then the two connecting rods 216 can be pulled upward by the two traction ropes 228 respectively, driving the blocking door 12 to move upward, so as to open the blocking door 12.

At the same time, a protective shell can be arranged on the outer periphery of the first stepping motor 226, so that the driving structure 22 can avoid the service life of the device from being reduced and the maintenance from being difficult due to water immersion; By starting the second stepping motor 36, the threaded rod 37 can be driven to rotate forward, and then the moving frame 38 threadedly connected with it can be driven to move downward. At the same time, the moving frame 38 will synchronously drive a plurality of fixed cylinders 34 to move downward, so that the bottom ends of the plurality of fixed cylinders 34 are inserted into the riverbed, thereby fixing the device; After the bottom end of the fixed cylinder 34 is inserted into the riverbed, by pulling the extension rod 397, the rotating column 393 can be driven to rotate. At the same time, the rotating column 393 will drive the two limiting shafts 3910 to rotate. When the two limiting shafts 3910 rotate, they will respectively squeeze the limiting grooves 396 to which they are movably connected, and then drive the insertion plate 395 to move away from the center of the fixed cylinder 34 in the sliding groove 392, so that the insertion plate 395 can be inserted into the soil of the riverbed, thereby increasing the fixing strength between the fixed cylinder 34 and the riverbed. Finally, rotate the fixing bolt 398 and insert the end of the fixing bolt 398 into the corresponding jack 394 to fix the extension rod 397.
