DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-10 An embodiment of the present invention discloses an anti-blocking narrow river gate, which is used to automatically clean pollutants in the river to ensure smooth drainage. Specifically, the gate includes a gate frame 2 installed in the river 1 and a gate plate 3 sliding in the gate frame 2. The gate frame 2 described in this embodiment can be set as a U-shaped structure, which is fixed inside the river 1. Slide grooves can be opened on the two inner sides of the gate frame 2. The gate plate 3 slides between two opposite slide grooves to achieve sliding guidance of the gate plate 3. The gate frame 2 is provided with a lifting mechanism 4 for driving the gate plate 3 to move;

[0040] Among them, a salvage mechanism 5 is arranged in front of the gate plate 3 along the water flow direction in the river channel 1. The salvage mechanism 5 is used to salvage pollutants in front of the gate plate 3 to avoid blockage problems at the subsequent gate frame 2. Preferably, two salvage mechanisms 5 described in this embodiment can be arranged, which are respectively arranged on both sides of the river bank of the river channel 1 to optimize the comprehensiveness of salvage. A power mechanism 6 is arranged on the rear side of the gate plate 3 along the water flow direction, and a transmission mechanism 7 is arranged inside the gate plate 3. The power mechanism 6 is driven by the water flow and drives the salvage mechanism 5 to move through the transmission mechanism 7.

[0041] That is, in this embodiment, water flow is used to drive the power mechanism 6 to provide energy, aiming to reduce energy demand and achieve energy conservation and emission reduction. Specifically, the power mechanism 6 drives the salvage mechanism 5 to perform salvage operations through the transmission mechanism 7. This design enables the salvage work of the water surface of the river channel 1 to be automatically completed during the process of opening the gate for drainage.

[0042] Reference Figure 3 In some embodiments, the lifting mechanism 4 of the present invention includes a screw 41 fixed on the gate plate 3;

[0043] The top of the gate frame 2 is rotatably connected to a nut gear 42, and the nut gear 42 is threadedly connected to the screw rod 41, wherein a motor 43 is also installed above the gate frame 2. It should be noted that, in this embodiment, the motor 43 can be installed on the upper end of the gate frame 2 through a bracket, and the bracket serves as a supporting base for the motor 43. A driving gear 46 meshing with the nut gear 42 is fixedly installed on the shaft end of the motor 43.

[0044] During specific operation, when it is necessary to lift the gate plate 3 for drainage, the driving gear 46 is driven to rotate by the motor 43. Since the driving gear 46 and the nut gear 42 are meshed for transmission, the nut gear 42 will rotate. By means of the threaded connection between the nut gear 42 and the screw 41, the entire gate plate 3 can be driven to move up and down through the linear movement of the screw 41. When the gate plate 3 moves upward, the river channel 1 can be opened for drainage. Otherwise, the river channel 1 will be cut off for water storage.

[0045] Reference Figure 3 On the basis of the above-mentioned embodiment, the lifting mechanism 4 in the present invention further includes a photovoltaic unit 44 and a control unit 45 installed on the gate frame 2. The photovoltaic unit 44, the control unit 45 and the motor 43 are electrically connected. Specifically, the photovoltaic unit 44 in the present invention may include a bracket installed on the gate frame 2 and a photovoltaic panel fixed on the bracket. Of course, a battery may also be configured for electricity storage. This type of photovoltaic power supply method is a conventional means for technicians in the relevant field and will not be elaborated here.

[0046] In addition, the control unit 45 described in this embodiment is electrically connected to the motor 43, and the control unit 45 can control the start and stop and forward and reverse rotation of the motor 43 to achieve the up and down lifting control of the gate 3. As a preferred embodiment, the control unit 45 described in this embodiment can also be connected to the server via a wireless module, so that the user can remotely control the movement of the motor 43, thereby further realizing the convenience of the motion control of the gate 3.

[0047] Reference Figure 3 , Figure 4As a preferred embodiment, the power mechanism 6 in the present invention includes two arms 61 rotatably connected to the gate plate 3, the two arms 61 are rotatably connected to the gate plate 3 through a rotating seat, a water wheel 62 is rotatably connected between the ends of the two arms 61, the water wheel 62 includes a central axis rotatably connected between the two arms 61, and a plurality of connecting plates are distributed on the outer circumference of the central axis. When water flows through, it continuously pushes the plurality of connecting plates to rotate, thereby realizing continuous rotation of the central axis, and a driving worm 63 is also rotatably connected to the end surface of the gate plate 3, and the driving worm 63 and the water wheel 62 are connected and transmitted through a power structure 64.

[0048] Optionally, the power structure 64 described in this embodiment can be configured as a pulley and a synchronous belt assembly, that is, pulleys are installed on the shaft of the water wheel 62 and the shaft of the driving worm 63, and the two pulleys are transmitted through a synchronous belt. In this way, when the water wheel 62 rotates due to the impact of the water flow, the driving worm 63 will be driven to rotate with the help of the power structure 64.

[0049] In other embodiments, in further embodiments, the above-mentioned power structure 64 can also be set as a sprocket and chain assembly, and its specific connection principle is the same as the connection principle of the above-mentioned pulley and synchronous belt, which will not be elaborated here.

[0050] Furthermore, in the initial state, the water wheel 62 is at the bottom of the river channel 1 due to the action of gravity, which can reduce the force on the two arms 61 when closing the gate. When opening the gate, the gate plate 3 moves upward, and the two arms 61 rotate due to the upward movement of the gate plate 3. In this embodiment, a stop boss is formed at the bottom of the gate plate 3. When the two arms 61 rotate to a certain angle, they will contact the stop boss to limit the position. At this time, the arms 61 cannot rotate. When following the further upward movement of the gate plate 3, the entire water wheel 62 will be pulled away from the bottom of the river channel 1. At this time, the water wheel 62 is no longer in contact with the bottom of the river channel 1. In this way, when the water flow hits the water wheel 62 when opening the gate, the smooth rotation of the water wheel 62 can be guaranteed. When the water wheel 62 rotates, the driving worm 63 can be driven to rotate by the power structure 64.

[0051] Reference Figure 5 , Figure 6 On the basis of the above-mentioned embodiment, the transmission mechanism 7 in the present invention comprises an energy storage worm wheel 71 rotatably connected to the rear side of the gate plate 3 along the water flow direction, a groove is provided on the end surface of the energy storage worm wheel 71, the energy storage worm wheel 71 and the driving worm 63 are meshed for transmission, a cavity is provided on the inner side of the gate plate 3, and a shaft 72 penetrating into the cavity is rotatably connected at the center of the energy storage worm wheel 71;

[0052] A coil spring 73 is fixedly connected between the groove wall of the energy storage worm wheel 71 and the shaft member 72 . The coil spring 73 is accommodated in the above-mentioned groove. A release component 74 for releasing the kinetic energy of the shaft member 72 is arranged in the cavity.

[0053] Reference Figure 7 , Figure 8 As a preference, the release assembly 74 in this embodiment includes a kinetic energy gear 741 fixedly connected to the shaft end of the shaft member 72, and the front end of the gate plate 3 is movably plugged with a sleeve 742 sleeved on the outside of the kinetic energy gear 741, and the inner end of the sleeve 742 is provided with a limit gear 743, and the teeth of the kinetic energy gear 741 and the limit gear 743 are both provided with chamfers, and the teeth of the two are engaged with each other. Of course, in the engaged state, the kinetic energy gear 741 and the limit gear 743 can also move relative to each other. The chamfer design is used to ensure that the shaft member 72 can rotate by the chamfer of the kinetic energy gear 741 against the chamfer of the limit gear 743 when the torque value of the coil spring 73 is too large. The specific principle will be described in detail later, and no further details will be given here;

[0054] Both sides of the gate plate 3 are rotatably connected with a worm 744, and the middle part of the worm 744 is connected to the shaft 72 through a transmission assembly 745. Specifically, in this embodiment, grooves are opened on both sides of the gate plate 3, and the grooves and the above-mentioned cavity are connected to each other. The worm 744 is vertically rotatably connected in the grooves. Of course, in order to facilitate the installation of the transmission assembly 745, the transmission assembly 745 described in this embodiment is installed inside the connection between the groove and the cavity.

[0055] Reference Figure 8 Optionally, the transmission assembly 745 described in this embodiment can also be configured as a pulley and a synchronous belt assembly, that is, two pulleys are installed on the outer side of the shaft 72, and a fixed pulley is also mounted on the middle part of the worm 744, and the two pulleys are connected and transmitted by a synchronous belt. It should be noted that in this embodiment, since the shaft 72 and the worm 744 extend in a vertical direction in space, the above-mentioned synchronous belt in this embodiment should be twisted.

[0056] In specific operation, when the lifting mechanism 4 drives the gate plate 3 to move upward to drain water, the water flow impacts the water wheel 62 to rotate it. Since the water wheel 62 and the driving worm 63 are driven by the power structure 64, when the water wheel 62 rotates, the driving worm 63 is driven to rotate. Since the driving worm 63 is meshed with the energy storage worm gear 71, it will synchronously drive the energy storage worm gear 71 to rotate continuously.

[0057] During this process, the other end of the shaft 72 cannot rotate due to the clamping action of the kinetic energy gear 741 and the limit gear 743. Therefore, when the energy storage worm gear 71 rotates, it will drive the coil spring 73 to rotate continuously to store energy. At the same time, since the structural design of the worm gear 71 is adopted in this scheme, with the help of its one-way transmission characteristic, the one-way rotation of the energy storage worm gear 71 can store energy in the coil spring 73, while making it impossible to reversely drive the worm 63.

[0058] Reference Figure 6 , Figure 7 , Figure 8 On the basis of the above embodiments, in order to ensure that the limit gear 743 maintains a certain clamping pre-tightening force on the kinetic energy gear 741 in the initial state, the sleeve 742 in this embodiment is located at the outer end of the gate plate 3 and is connected to a trigger plate 746, and a plurality of springs 747 are connected between the trigger plate 746 and the gate plate 3. Of course, in order to prevent the trigger plate 746 from rotating circumferentially along the sleeve 742, in this embodiment, plug rods can be installed at the four corners of the trigger plate 746, and the plug rods and the gate plate 3 are plugged in. At the same time, the springs 747 can be sleeved on the outside of the plug rods, so that the linear plug-in movement of the trigger plate 746 can be limited and rotational movement cannot be performed.

[0059] Reference Figure 8 Furthermore, since the teeth of the kinetic energy gear 741 and the limit gear 743 in this scheme are both provided with chamfers, when the energy storage worm gear 71 rotates continuously to make the coil spring 73 reach a certain torque value, the clamping pre-tightening force between the kinetic energy gear 741 and the limit gear 743 will be overcome. At this time, the chamfer of the kinetic energy gear 741 will rotate along the chamfer of the limit gear 743 to resist the entire sleeve 742 from moving a small distance inward and squeezing the spring 747, that is, the entire shaft 72 will rotate. When the shaft 72 rotates, the worm 744 on both sides will be driven to rotate through the transmission assembly 745, thereby completing the transmission of the salvage mechanism 5, so that the salvage mechanism 5 can salvage the pollutants on the water surface of the river channel 1 and complete the automatic cleaning operation of the pollutants.

[0060] Reference Figure 3 Optionally, in this embodiment, a cover plate 31 covering the outside of the energy storage worm gear 71 is connected to the end surface of the gate plate 3, and the bottom of the cover plate 31 has a avoidance opening for avoiding the driving worm 63. The driving worm 63 is meshed with the energy storage worm gear 71 at the avoidance opening. In this embodiment, the cover plate 31 is designed to shield and protect the energy storage worm gear 71. Preferably, the cover plate 31 described in this embodiment can be connected to the gate plate 3 by fasteners such as bolts to facilitate disassembly and maintenance.

[0061] Reference Fig. 9 , Fig.10, in some embodiments, the salvage mechanism 5 of the present invention includes a floating frame 51;

[0062] An accommodation position is provided at the river bank of the river channel 1. Specifically, the accommodation position described in this embodiment can be set as a groove formed by cement pouring. The floating frame 51 is movably connected in the accommodation position and is slidably connected with the gate frame 2. Specifically, in this embodiment, a guide column is provided on the side of the gate frame 2. One end of the floating frame 51 is movably plugged into the guide column. At the same time, a guide groove is also provided on the side of the gate frame 2. The floating frame 51 slides in the guide groove to achieve sliding guidance.

[0063] Furthermore, a compression spring 52 is connected between the floating frame 51 and the gate frame 2, a collecting rake 53 is rotatably connected to the inner side of the floating frame 51, a worm gear shaft 54 ​​is installed on the shaft end of the collecting rake 53, the compression spring 52 is sleeved on the outer side of the worm gear shaft 54, and the two sides of the compression spring 52 are respectively in contact with the side edges of the gate frame 2 and the floating frame 51, and the design of the compression spring 52 is used to achieve force support for the floating frame 51 and reset after displacement, and the worm gear shaft 54 ​​and the worm 744 are meshed for transmission;

[0064] Specifically, in the present invention, by adopting the worm gear shaft 54, it can be ensured that during the lateral movement of the floating frame 51, the worm gear shaft 54 ​​can always be meshed and transmitted with the worm 744. At the same time, during the up and down movement of the gate plate 3, the worm 744 can always be in a power transmission state with the worm gear shaft 54. The structural design is simple and ingenious.

[0065] A resisting rod 55 that resists the trigger plate 746 is fixedly installed on the inner side of the floating frame 51 .

[0066] In the above-mentioned embodiment, the energy storage worm wheel 71 rotates, and when the torque value of the coil spring 73 is greater than the elastic force value of the spring 747, the relative position between the kinetic energy gear 741 and the limit gear 743 is changed, so as to achieve the purpose of rotating the shaft member 72. In this way, the entire shaft member 72 rotates intermittently, that is, the salvage mechanism 5 is in a slow working state;

[0067] In this embodiment, the floating frame 51 is slidably connected to the gate frame 2. When the gate is opened to drain water, if too much pollutants accumulate on the collecting rake 53, the pollutants will increase the force-bearing area of ​​the collecting rake 53 when water flows through. Therefore, the collecting rake 53 will move to one side of the gate plate 3 after being stressed and squeeze the compression spring 52. At this time, the resistance rod 55 on the collecting rake 53 will resist the trigger plate 746 to move inward. When the trigger plate 746 moves inward, it can drive the limit gear 743 and the kinetic energy gear 741 to separate. In this state, the shaft 72 is in a free state. Therefore, when the energy storage worm gear 71 rotates to store energy, the shaft 72 will rotate rapidly and continuously to ensure that the collecting rake 53 rotates rapidly and continuously to salvage the pollutants on the river surface.

[0068] Reference Figure 1 Optionally, the embodiment of the present invention further includes a collection pool 56 installed at the embankment of the river channel 1. When installing the collection pool 56, a groove can be first dug on the embankment, and the collection pool 56 can be installed in the groove. The collection pool 56 is designed to realize centralized collection and treatment of pollutants to improve the convenience of subsequent manual treatment of pollutants. Of course, the collection pool 56 described in the present invention is also provided with two, which are used to adapt to the pollutant salvage and collection of the two salvage mechanisms 5;

[0069] A guide rake 57 is fixedly mounted on the upper side of the floating frame 51 , and a groove is provided on the end surface of the guide rake 57 that matches the teeth of the collecting rake 53 one by one. The tail end of the guide rake 57 slides over the opening of the collecting pool 56 .

[0070] The guide rake 57 described in this embodiment is used to scrape the pollutants on the collecting rake 53, so that when the collecting rake 53 is in a continuous rotating cleaning process, the pollutants can be scraped on the guide rake 57, and finally slide along the guide rake 57 and fall into the interior of the collecting pool 56 for centralized collection. Secondly, the guide rake 57 in the present invention is movably connected above the collecting pool 56 to ensure that when the floating frame 51 moves, the guide rake 57 can always maintain mobile adaptation.

[0071] In summary, the present invention provides energy by adopting a water flow-driven power mechanism 6, aiming to reduce energy demand and achieve energy conservation and emission reduction. Specifically, the power mechanism 6 drives the salvage mechanism 5 to perform salvage operations through the transmission mechanism 7. This design enables the salvage work on the water surface of the river 1 to be automatically completed during the process of opening the gate to drain water. Secondly, the salvage mechanism 5 in the present invention adopts a floating design. When too many pollutants accumulate, it will move to trigger the transmission mechanism 7, and the salvage speed can be automatically adjusted according to the pollutant situation on the water surface of the river 1. The overall structural design is simple and novel, which greatly improves the salvage efficiency of surface pollutants and effectively avoids blockage when the gate of the river 1 is opened.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
