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 making creative efforts shall fall within the protection scope of the present invention.

[0023] During specific implementation: As Figures 1-6As shown in the figure, a rotary trash rack for the water inlet of a river sluice includes a support housing 1 and a trash rack body 2: A trash rack body 2 is connected and arranged between the inner walls on both sides of the support housing 1. An external rotary cleaning mechanism 3 for cleaning river impurities is provided outside the trash rack body 2. A monitoring and control mechanism 4 for monitoring the operating speed of the above rotary cleaning mechanism 3 is provided outside the support housing 1. Positioning support mechanisms 5 for fixing the whole device are symmetrically arranged on the sides of the support housing 1. The rotary cleaning mechanism 3 includes a first support sprocket 31, a second support sprocket 32, a third support sprocket 33, a drive chain 34, a support shaft 35, a drive motor 36 and a cleaning plate 37. The first support sprocket 31 and the second support sprocket 32 are symmetrically and rotatably installed on the inner walls on both sides of the support housing 1 near the top position. The first support sprocket 31 and the second support sprocket 32 are arranged in a parallel position relationship. The third support sprocket 33 is symmetrically and rotatably installed on the inner walls on both sides of the support housing 1 near the bottom position. A drive chain 34 is connected between the first support sprocket 31, the second support sprocket 32 and the third support sprocket 33. The first support sprocket 31, the second support sprocket 32 and the third support sprocket 33 are all arranged outside the support shaft 35. Both ends of the support shaft 35 are rotatably installed on the side inner walls of the support housing 1. The extended end of the support shaft 35 inside the first support sprocket 31 is connected to the drive motor 36. The drive motor 36 is connected to the side outer wall of the support housing 1. Two sets of drive chains 34 are provided, and cleaning plates 37 are connected and installed in an equidistant and circumferential manner between the two sets of drive chains 34; When the drive motor 36 is turned on, it will automatically drive the support shaft 35 inside the first support sprocket 31 to rotate. Subsequently, the first support sprocket 31 will automatically rotate under the drive of the support shaft 35. Furthermore, when the first support sprocket 31 rotates, it will automatically drive the drive chain 34 to rotate, thereby driving the second support sprocket 32 and the third support sprocket 33 to rotate synchronously. Here, the support shafts 35 provided inside the second support sprocket 32 and the third support sprocket 33 play a role of limiting and supporting their rotation. And the design of the support shaft 35 can synchronously drive the two sets of first support sprocket 31, second support sprocket 32, third support sprocket 33 and drive chain 34 to synchronously drive. At the same time, when the two sets of drive chains 34 rotate synchronously, they will also synchronously drive multiple cleaning plates 37 to rotate. When the cleaning plates 37 rotate, they will automatically convey and clean the fallen leaves and impurities accumulated on the side of the trash rack body 2. For the specific cleaning process, refer to the rotary trash rack in the prior art to understand.

[0024] The monitoring and control mechanism 4 includes a transmission shaft 41, a support cover 42, and a driving gear 43. The outer side wall of the second support sprocket 32 is connected to one end of the transmission shaft 41. The other end of the transmission shaft 41 is rotatably installed on the inner side wall of the support cover 42. The support cover 42 is connected to the outer side wall of the support housing 1. A driving gear 43 is arranged outside the transmission shaft 41 located inside the support cover 42. A transmission gear 44 is meshed and installed on the side of the driving gear 43. The transmission gear 44 is arranged outside the monitoring shaft 45. One end of the monitoring shaft 45 is rotatably installed on the outer side wall of the support housing 1. The other end of the monitoring shaft 45 is connected to a rotational speed monitoring sensor 46. The rotational speed monitoring sensor 46 is connected to the inner side wall of the support cover 42. A power supply member 47 and a controller 48 are arranged on the top outer wall of the support housing 1. Both the power supply member 47 and the controller 48 are arranged inside the protective cover 49, and the bottom outer wall of the protective cover 49 is connected to the top outer wall of the support housing 1. Here, before the rotational speed monitoring sensor 46 is used, the monitoring threshold range needs to be set according to the normal operating rotational speed of the device. Subsequently, the rotational speed monitoring sensor 46 is turned on. When the second support sprocket 32 rotates, it will also synchronously drive the transmission shaft 41 to rotate. When the transmission shaft 41 rotates, it will automatically drive the driving gear 43 to rotate, thereby driving the transmission gear 44 to rotate. Subsequently, when the transmission gear 44 rotates, it will automatically drive the monitoring shaft 45 to rotate. The setting of the rotational speed monitoring sensor 46 here is to understand the rotational speed of the monitoring shaft 45 in real time. The specific installation method can be carried out according to the existing technical standards, as long as the rotational speed monitoring sensor 46 can monitor the rotational speed of the monitoring shaft 45. Since the rotational speed of the monitoring shaft 45 is directly proportional to the rotational speed of the second support sprocket 32, once the rotational speed of the second support sprocket 32 becomes slower, it will cause the rotational speed of the monitoring shaft 45 to become slower. And the rotational speed of the second support sprocket 32 is directly affected by the transmission speed of the cleaning plate 37. Once the lowermost cleaning plate 37 is stuck by a large stone or obstructs the transmission, at this time, when the cleaning plate 37 is stuck, the transmission chain 34 cannot operate normally. And when the transmission chain 34 cannot transmit, it will directly cause the second support sprocket 32 to not operate. At this time, the rotational speed of the second support sprocket 32 drops significantly, and at the same time, it directly affects the rotational speed of the monitoring shaft 45. Then, once the rotational speed of the monitoring shaft 45 is lower than the monitoring range of the rotational speed monitoring sensor 46, the rotational speed monitoring sensor 46 will automatically transmit information to the controller 48. At this time, the controller 48 will automatically control the power supply member 47 to stop supplying power to the driving motor 36, so as to achieve the effect of promptly stopping the operation of the device. A more advanced method is to connect to a relevant system for monitoring. Once it is found that the device stops, the signal can be directly received through the system, so as to facilitate the staff to promptly repair the device.

[0025] The positioning and supporting mechanism 5 includes a mounting base plate 51 and a support member 52. The mounting base plates 51 are symmetrically arranged on the outer walls on both sides of the support housing 1. The support member 52 is arranged on the top outer wall of the mounting base plate 51. The support member 52 is arranged in a triangular structure and is connected to the side outer wall of the support housing 1. The positioning and mounting blocks 53 are symmetrically arranged on the outer walls on both sides of the mounting base plate 51. A positioning hole 54 is penetrated and opened on the top outer wall of the positioning and mounting block 53. A ground nail 55 is arranged inside the positioning hole 54; when it is necessary to install the device into the river channel, at this time, only need to adjust the device to a suitable position and then place it into the river channel. Here, it is necessary to ensure that the two mounting base plates 51 are in contact with the upper surface of the river bank. Subsequently, directly drive the ground nail 55 through the positioning hole 54 and into the river bank foundation to complete the installation.

[0026] When the present utility model is in use, when it is necessary to install the device into the river channel, at this time, only need to adjust the device to a suitable position and then place it into the river channel. Here, it is necessary to ensure that the two mounting base plates 51 are in contact with the upper surface of the river bank. Subsequently, directly drive the ground nail 55 through the positioning hole 54 and into the river bank foundation to complete the installation;

[0027] When the driving motor 36 is turned on, it will automatically drive the support shaft 35 inside the first support sprocket 31 to rotate. Subsequently, the first support sprocket 31 automatically rotates under the drive of the support shaft 35. Furthermore, the rotation of the first support sprocket 31 will automatically drive the transmission chain 34 to rotate and then drive the second support sprocket 32 and the third support sprocket 33 to rotate synchronously. Here, the support shafts 35 arranged inside the second support sprocket 32 and the third support sprocket 33 play a role in limiting and supporting their rotation. And the design of the support shaft 35 can synchronously drive two groups of the first support sprocket 31, the second support sprocket 32, the third support sprocket 33 and the transmission chain 34 to synchronously drive. At the same time, when the two groups of transmission chains 34 rotate synchronously, they will also synchronously drive multiple groups of cleaning plates 37 to rotate. When the cleaning plates 37 rotate, they will automatically convey and clean the fallen leaves, impurities, etc. accumulated on the side of the trash rack body 2.

[0028] Before use, the rotational speed monitoring sensor 46 here needs to set the monitoring threshold range according to the rotational speed of the device during normal operation. Then, the rotational speed monitoring sensor 46 is turned on. When the second support sprocket 32 rotates, it will synchronously drive the transmission shaft 41 to rotate. When the transmission shaft 41 rotates, it will automatically drive the drive gear 43 to rotate, which in turn drives the transmission gear 44 to rotate. Subsequently, when the transmission gear 44 rotates, it will automatically drive the monitoring shaft 45 to rotate. The rotational speed monitoring sensor 46 is provided to understand the rotational speed of the monitoring shaft 45 in real time. The specific installation method can be carried out according to the existing technical standards, as long as the rotational speed monitoring sensor 46 can monitor the rotational speed of the monitoring shaft 45. Since the rotational speed of the monitoring shaft 45 is directly proportional to the rotational speed of the second support sprocket 32, once the rotational speed of the second support sprocket 32 becomes slower, the rotational speed of the monitoring shaft 45 will also become slower. The rotational speed of the second support sprocket 32 is directly affected by the transmission speed of the cleaning plate 37. Once the lowermost cleaning plate 37 is stuck by a large stone or obstructs the transmission, the stuck cleaning plate 37 will cause the transmission chain 34 to be unable to operate normally. If the transmission chain 34 cannot transmit power, it will directly cause the second support sprocket 32 to stop operating. At this time, the rotational speed of the second support sprocket 32 drops significantly, which directly affects the rotational speed of the monitoring shaft 45. Furthermore, once the rotational speed of the monitoring shaft 45 is lower than the monitoring range of the rotational speed monitoring sensor 46, the rotational speed monitoring sensor 46 will automatically transmit the information to the controller 48. At this time, the controller 48 will automatically control the power supply component 47 to stop supplying power to the drive motor 36, so as to achieve the effect of promptly stopping the operation of the device. A more advanced method is to connect to a relevant system for monitoring. Once it is found that the device has stopped, the signal can be directly received through the system, so as to facilitate the staff to promptly repair the device.

[0029] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
