Description

Technical Field

[0001] The present invention relates to the technical field of floating gates, and in particular to a monitoring device and method for a floating gate. Background Art

[0002] In existing buoy gate monitoring devices, a buoy and a swing arm are usually used to close or open the gate. However, the buoy and the gate in the existing technology are mostly fixed. Due to the influence of external factors such as wind, the height of the buoy on the water surface will constantly change, which not only affects the sealing effect of the gate, but also causes rapid wear of the gate mechanism and its components. In addition, the traditional buoy gate mechanism lacks an effective automatic adjustment mechanism to adapt to water level fluctuations, which limits its stability and reliability under complex hydrological conditions.

[0015] In a feasible embodiment, the monitoring device of the buoy gate is also provided with a cleaning mechanism, which includes: a pump body, fixedly mounted on the top outer wall of the gate enclosure; a hose, one end of which is connected to the output end of the pump body and the other end extends toward the gate assembly; and a water immersion sensor, fixedly mounted on the bottom end of the outer wall of the buoy.

[0016] In a feasible embodiment, the inner cavity of the reinforcing rod is in a hollow state, the cavity of the reinforcing rod is connected to the output end of the hose, and the bottom end of the reinforcing rod is also provided with a first fan-shaped nozzle, and the first fan-shaped nozzle is facing the bottom end of the door panel; the inner cavity of the door panel is also provided with a second fan-shaped nozzle connected to the reinforcing rod, and the second fan-shaped nozzle is located on the other side of the inner side of the door panel opposite to the first fan-shaped nozzle, and the second fan-shaped nozzle does not protrude from the outer wall of the door panel.

By setting that the buoy can swing slightly independently relative to the gate assembly, the sealing performance of the gate assembly and the durability of the equipment are ensured, thereby improving operational reliability.

Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also include elements inherent to such process, method, article or equipment.

The term "two or more" includes two or more than two cases. Example

[0037] See also Figures 1 to 10 As shown, in the first aspect of an embodiment of the present application, a monitoring device for a floating gate is provided, comprising an installation frame 1 and a gate enclosure 2 arranged on the inner side of the installation frame 1, a gate opening being opened on the gate enclosure 2, and a floating gate mechanism 3 is also provided on the gate enclosure 2, the floating gate mechanism 3 being rotatably arranged on the gate enclosure 2, the floating gate mechanism 3 being used to close or open the gate opening, and the state of the floating gate mechanism 3 can be controlled by a controller.

[0038] The buoy gate monitoring device of the present application realizes efficient control of the gate; further, the floating gate mechanism 3 is composed of a buoy 31, a steering seat 32, a gate assembly 33, a reinforcing rod 34, a swing rod 35 and a movable seat 36. The buoy 31 floats up and down according to the large changes in water level, driving the swing rod 35 to move, thereby realizing the opening or closing of the gate; the steering seat 32 is fixed above the gate and serves as the fulcrum of the entire floating gate mechanism 3; the movable seat 36 is located on the outside of the steering seat 32, and through the movable seat 36, the buoy 31 is connected to the steering seat 32 through the swing rod 35 and the movable seat 36, allowing the swing rod 35 to swing within a certain range to adapt to small fluctuations in the water level.

[0039] In addition, the gate assembly 33 is connected to the steering seat 32 through a reinforcing rod 34, and its design can effectively block the gate and prevent water from flowing through; the reinforcing rod 34 not only provides the necessary strength and stability for the gate assembly 33, but also transmits the floating action of the float 31 to the gate assembly 33 through the connection with the steering seat 32, the movable seat 36 and the swing rod 35, thereby achieving precise control; the float 31 and the swing rod 35 can swing within the range allowed by the movable seat 36 without affecting the sealing state of the gate assembly 33; therefore, the present application achieves precise control of the gate, improves sealing, reduces wear caused by water level fluctuations, and significantly improves the service life of the entire monitoring device.

[0040] In order to reduce the impact of impurities in the water on the floating gate mechanism 3, an interception net 5 is optionally provided on the inner side of the gate enclosure 2. The interception net 5 can filter the water flow entering the gate enclosure 2 to prevent garbage from flowing into the water area on the output side of the gate, thereby improving the functionality of the device.

[0041] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 and Figure 10 As shown, in some examples, further, the steering seat 32 also includes: a central rotating shaft 321, a first boss 322, a rotating collar 323, a second boss 324 and a push rod motor 325, the central rotating shaft 321 can be rotatably set on the gate enclosure 2, and the central rotating shaft 321 is connected to the gate assembly 33 through the reinforcing rod 34; the first boss 322 is fixedly arranged on the outside of the central rotating shaft 321; the rotating collar 323 can be rotatably sleeved on the outside of the central rotating shaft 321, and a movable seat 36 is fixedly provided on the outer wall of the rotating collar 323; the second boss 324 is fixedly arranged on the outside of the rotating collar 323; the two ends of the push rod motor 325 are rotatably connected between the first boss 322 and the second boss 324, and the push rod motor 325 is used to change the angle formed among the swing arm 35, the steering seat 32 and the gate assembly 33.

[0042] In this example, the steering seat 32 allows dynamic adjustment between the gate assembly 33 and the buoy 31 through the rotation ability of the central shaft 321; the central shaft 321 serves as a connection point and is connected to the gate assembly 33 through the reinforcing rod 34, ensuring the stability and responsiveness of the gate assembly 33; the rotating collar 323 can be rotatably mounted on the outside of the central shaft 321, and the movable seat 36 on its outer wall is further connected to the buoy 31 through the swing rod 35, allowing the swing rod 35 and the buoy 31 to swing within a certain range, so as to adapt to the water level changes and flexibly adjust the appropriate timing of opening and closing the gate; the second protrusion 324 is fixed to the outside of the rotating collar 323, and together with the first protrusion 322 As the fulcrum of the push rod motor 325; the two ends of the push rod motor 325 are respectively connected between the first protrusion 322 and the second protrusion 324. Its main function is to change the angle formed by the swing rod 35, the steering seat 32 and the gate assembly 33 through telescopic movement to set a higher or lower water level to trigger the opening or closing mechanism of the gate; in addition, when the opening and closing state of the gate needs to be adjusted, the float 31 floats on the water surface and maintains a relatively fixed position. Through the telescopic movement of the push rod motor 325, the gate assembly 33 is pushed to rotate, thereby realizing active control of the gate; therefore, this example can perform active adjustments under different water level conditions, thereby improving the adaptability to environmental changes.

[0043] like Figures 6 to 8 As shown, in some examples, further, the gate assembly 33 includes: a door panel 331, a telescopic motor 332, a first travel switch 333, a limit seat 334 and a contact seat 335; the door panel 331 is fixedly connected to the end of the reinforcing rod 34 away from the steering seat 32; and the door panel 331 corresponds to the position of the gate; the telescopic motor 332 is fixedly arranged at the edge position of the door panel 331, and a card block is provided on the output end of the telescopic motor 332; the first travel switch 333 is fixedly installed at the edge position of the door panel 331; the limit seat 334 is fixedly arranged on the gate enclosure 2, and corresponds to the position of the telescopic motor 332, and is used to limit the card block at the output end of the telescopic motor 332; the contact seat 335 is fixedly arranged on the gate enclosure 2, and corresponds to the position of the first travel switch 333, and is used to trigger the first travel switch 333.

[0044] In this example, the gate assembly 33 includes a door panel 331, which serves as the main closing structure, is fixed on the reinforcing rod 34 and corresponds to the gate position, and is responsible for directly blocking or opening the gate; the telescopic motor 332 is installed on the edge of the door panel 331, and the block at its output end is used to engage or disengage the limit seat 334, which is used to limit the locking of the position of the door panel 331 in the gate blocking state; the first travel switch 333 is installed on the edge of the door panel 331. When the door panel 331 is in the position blocking the gate, the first travel switch 333 contacts the contact seat 335, thereby triggering the first travel switch 333 and sending a signal indicating that the position is locked.

[0045] The working principle and process are as follows: when the water level drops and the gate needs to be opened, the telescopic motor 332 is started according to the instruction of the controller, driving the card block to retract in the limit seat 334; after the card block retracts, the locked state of the door panel 331 position is released, and the gate can be opened as the float 31 moves downward; when the water level rises and the gate needs to be closed, the float 31 rises and drives the door panel 331 to move toward the gate. When it reaches the position where the gate is fully closed, the first travel switch 333 is triggered by the contact seat 335, and a signal is sent back to the controller, indicating that the door panel 331 has reached the correct position; the controller controls the telescopic motor 332 to drive the card block to be stuck in the limit seat 334, keeping the door panel 331 locked; therefore, this example enhances the automation level of the device and improves the convenience and safety of operation through precise mechanical control and electronic feedback.

[0046] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, in some examples, further, the monitoring device of the buoy gate is also provided with a cleaning mechanism 4, which includes: a pump body 41, a hose 42 and a water immersion sensor 43. The pump body 41 is fixedly mounted on the top outer wall of the gate enclosure 2; one end of the hose 42 is connected to the output end of the pump body 41, and the other end extends to the gate assembly 33; the water immersion sensor 43 is fixedly mounted on the bottom end of the outer wall of the buoy 31.

[0047] In this example, it can be understood that the cleaning mechanism 4 is the part of the buoy gate monitoring device used to maintain the cleanliness and normal operation of the equipment; the pump body 41 is fixed on the top outer wall of the gate enclosure 2, and is responsible for providing the gas or liquid required for cleaning. When the sludge cleaning source is liquid, a nearby surface water source can be selected; the gas or liquid pumped out by the pump body 41 is transported to the gate assembly 33 through the hose 42, thereby completing the sludge cleaning. The water immersion sensor 43 is installed at the bottom end of the outer wall of the buoy 31, and is used to monitor in real time whether the buoy 31 is immersed in water.

[0048] The working principle and process are as follows: when the water immersion sensor 43 detects that the float 31 is suspended above the water surface, that is, there is no water covering the bottom of the float 31, this may mean that sludge or other sediment has accumulated at the bottom of the door panel 331, resulting in the door panel 331 being stuck and unable to open normally after the water level drops, which affects the normal operation of the gate; at this time, the water immersion sensor 43 transmits a signal to the controller, and the controller immediately starts the pump body 41, and sprays air or water to the lower half of the door panel 331 through the hose 42 to remove sediment or silt; the cleaning process continues until the water immersion sensor 43 detects that the bottom of the float 31 is covered with water again, indicating that the cleaning work is completed. At this time, the controller turns off the pump body 41 and the equipment returns to normal monitoring status; therefore, by automatically detecting and cleaning sediments, the need for manual intervention is reduced and maintenance costs are reduced; equipment failures caused by difficulty in opening the door panel 331 are avoided, and the intelligence level of the entire device is improved.

[0049] like Figure 1 、 Figure 2 and Figure 5 As shown, in some examples, further, the inner cavity of the reinforcing rod 34 is in a hollow state, the cavity of the reinforcing rod 34 is connected to the output end of the hose 42, and the bottom end of the reinforcing rod 34 is also provided with a first fan-shaped nozzle 341, and the first fan-shaped nozzle 341 faces the bottom end of the door panel 331; the inner cavity of the door panel 331 is also provided with a second fan-shaped nozzle 342 connected to the reinforcing rod 34, and the second fan-shaped nozzle 342 is located on the other side of the inner side of the door panel 331 opposite to the first fan-shaped nozzle 341, and the second fan-shaped nozzle 342 does not protrude from the outer wall of the door panel 331.

[0050] In this example, the inner cavity of the reinforcing rod 34 is in a hollow state, allowing it to be connected to the output end of the hose 42 to form a channel, so that the cleaning medium (such as air or water flow) can be transported from the pump body 41 through the hose 42 to the cavity of the reinforcing rod 34; the first fan-shaped nozzle 341 at the bottom end of the reinforcing rod 34 faces the bottom end of the door panel 331, and the second fan-shaped nozzle 342 in the inner cavity of the door panel 331 is connected to the reinforcing rod 34, located on the other side opposite to the first fan-shaped nozzle 341, and does not protrude. This design ensures that the cleaning medium can act on both the inside and outside of the door panel 331 at the same time without affecting the daily opening and closing actions.

[0051] The working principle and process are as follows: when the controller receives the signal from the water immersion sensor 43, the float 31 is suspended above the water surface. When there may be sludge accumulation at the bottom of the door panel 331, the pump body 41 starts and transports the cleaning medium to the cavity of the reinforcing rod 34 through the hose 42; the cleaning medium flows in the inner cavity of the reinforcing rod 34 and is sprayed to the bottom of the door panel 331 through the first fan-shaped nozzle 341. At the same time, the second fan-shaped nozzle 342 also sprays at the corresponding position on the inner side of the door panel 331, forming a synchronous cleaning effect on the inside and outside, effectively removing the sediment and sludge at the bottom of the door panel 331; this two-way injection mechanism increases the cleaning range of the sludge near the bottom end of the door panel 331, ensuring that the cleaning medium can cover a large area of ​​the bottom of the door panel 331; ensuring that the gate monitoring device can operate stably for a long time under various environmental conditions.

[0052] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 As shown, in some examples, further, the movable seat 36 includes: a sector seat 361, a swing shaft 362, two elastic support pieces 363, a fixed frame 364 and a second travel switch 365; the sector seat 361 is fixedly mounted on the outer wall of the rotating ring 323; the swing shaft 362 is rotatably mounted on one side of the sector seat 361 close to the rotation axis of the rotating ring 323, and the swing shaft 362 is located on the middle dividing line of the sector seat 361, and the end of the swing rod 35 is sleeved on the swing shaft 362, so that the swing shaft 362 divides the angle of the sector seat in half; the two elastic support pieces 36 3 are respectively arranged on the inner walls of the upper and lower ends of the sector-shaped seat 361. The end of the elastic support piece 363 away from the swing shaft 362 is fixed, and the other end of the elastic support piece 363 is a movable end. The middle part of each elastic support piece 363 has an elastic protrusion, which abuts against the outer wall of the swing rod 35. The fixed frame 364 is fixedly fastened to the inner wall of the sector-shaped seat 361 and movably sleeved on the movable end of the elastic support piece 363. The second travel switch 365 is fixedly mounted on the outer wall of the bottom end of the sector-shaped seat 361. The second travel switch 365 has a contact located on the inner side of the elastic protrusion.

[0053] In this example, the movable seat 36 is a component in the buoy gate monitoring device that ensures that the door panel 331 is not affected by the slight movement of the buoy 31 on the water surface; the fan-shaped seat 361 is fixed on the outer wall of the rotating ring 323, serving as the base structure of the entire movable seat 36; the swing shaft 362 is installed in the fan-shaped seat 361 to ensure the stability of the rotation of the swing rod 35 when following the slight fluctuations of the water surface; the end of the swing rod 35 is sleeved on the swing shaft 362, and the other end of the swing rod 35 is connected to the buoy 31, so after the buoy 31 moves up or down slightly following the movement of the water surface, the swing rod 35 is allowed to rotate within a certain range without triggering the drive steering of the center shaft 321 and the door panel 331.

[0054] In addition, an elastic support sheet 363 is provided in the movable seat 36, and the two ends of the elastic support sheet 363 are respectively fixed and movably provided. The elastic protrusion in the middle abuts against the outer wall of the swing rod 35, providing necessary elastic support and buffering effect, allowing the swing rod 35 to have a slight swing space when the water fluctuates, while limiting its swing amplitude. Although this device has a swinging area of ​​the buoy 31 that does not affect the door panel 331, the elastic support sheets 363 at both ends are provided, so that when the door panel 331 is not locked, the swing rod 35 still has a default angle with the reinforcing rod 34. In this way, when the water level rises, the swing rod 35 is also in the center position of the movable seat 36 under the abutment of the elastic support sheet 363, and can still accurately drive the door panel 331 to move close to the gate, so as to achieve the goal of driving the door panel 331 to restore the closed state of the gate under the predetermined water level.

[0055] The second travel switch 365 is installed at the bottom end of the fan-shaped seat 361, and its contact is located on the inner side of the elastic protrusion. When the door panel 331 is in the locked state and the water level drops significantly, the swing rod 35 presses down the elastic support piece 363 due to the drop of the float 31, and at the same time presses the contact, and the contact sends a signal to the controller; this signal indicates that the position of the float 31 has dropped to a certain extent, and the state of the door panel 331 needs to be changed to open, and then the controller controls the telescopic motor 332 to drive the block to release the limit on the door panel 331, and the door panel 331 can move with the float 31, thereby opening the gate; so that the gate assembly 33 can respond to water level changes in time and maintain the best working state.

[0056] In some examples, further, the gate assembly 33 also includes a controller having two signal input terminals, which are respectively connected to the first travel switch 333 and the second travel switch 365 ; the output terminal of the controller is connected to the telescopic motor 332 .

[0057] In this example, the controller is responsible for logic processing and command issuance in the gate assembly 33; the controller has two signal input terminals that receive signals from the first limit switch 333 and the second limit switch 365 respectively; the first limit switch 333 and the second limit switch 365 respectively correspond to different position states of the door panel 331, and the first limit switch 333 is triggered when the door panel 331 completely closes the gate, while the second limit switch 365 is triggered when the float 31 drops to a certain position.

[0058] When the door panel 331 completely blocks the gate, the first travel switch 333 is triggered and sends a signal to the controller. The telescopic motor 332 pushes the block into the limit seat 334, thereby locking the position of the door panel 331; if the water level drops, the float 31 drops accordingly, pressing the elastic support sheet 363, triggering the second travel switch 365, which sends a signal to the controller. After the controller receives the signal, the controller immediately sends an instruction to the telescopic motor 332 to adjust the position of the block, allowing the door panel 331 to move away from the gate as the float 31 drops, thereby realizing automatic opening of the gate.

[0059] In some examples, further, the controller is also provided with a third signal input terminal, the third signal input terminal is connected to the Internet of Things module 6, and the output terminal of the controller is also connected to the push rod motor 325.

[0060] In this example, the third signal input terminal added to the controller is connected to the Internet of Things module 6, which improves the intelligence and remote control capabilities of the buoy gate monitoring device; the Internet of Things module 6 is responsible for collecting data from the controller and transmitting it to a remote server or the user's smart device, and can also receive remote instructions and feedback to the controller; in this way, the user can monitor the gate status in real time through the Internet and remotely adjust the opening and closing of the gate when necessary.

[0061] This example can be applied to the situation where the water level remains unchanged. When the user issues an instruction on the gate opening and closing status through the smart device, the instruction is transmitted to the controller through the Internet of Things module 6; the controller controls the action of the push rod motor 325 through its output end according to the received instruction; the push rod motor 325 retracts and contracts according to the instruction, thereby changing the angle between the float 31 and the gate assembly 33, thereby achieving fine adjustment of the gate opening and closing state; for example, if the gate needs to be closed only at a higher water level, the controller issues a retraction instruction for the push rod motor 325, and the retraction instruction of the push rod motor 325 can control the retraction of the push rod motor 325. The retraction of the push rod motor 325 can increase the angle between the swing arm 35, the steering seat 32 and the door panel 331, so that the door panel 331 can completely close the gate only when the water level rises to a higher position.

[0062] It should also be understood that when the angle between the swing arm 35, the steering seat 32 and the door panel 331 in this device is small, only a lower water level is required to drive the door panel to close the gate. When the angle between the swing arm 35, the steering seat 32 and the door panel 331 in this device is large, a higher water level is required to drive the door panel to close the gate.

[0063] In some examples, further, the controller is further provided with a fourth signal input terminal, the fourth signal input terminal is connected to the water immersion sensor 43 , and the output terminal of the controller is further connected to the pump body 41 .

[0064] In this example, the fourth signal input terminal added to the controller is connected to the water immersion sensor 43, providing an automated cleaning and maintenance mechanism for the buoy gate monitoring device; the water immersion sensor 43 is responsible for real-time monitoring of whether the bottom of the buoy 31 is immersed in water, so as to determine whether there is sludge accumulation or other conditions that require cleaning; when the sensor detects that the buoy 31 is suspended or sludge accumulation causes cleaning needs, it will send a signal to the controller; cooperate with the cleaning mechanism 4 to spray the cleaning medium, so that the cleaning medium acts on the inside and outside of the door panel 331, effectively removing sludge and other sediments, and restoring the normal operation of the door panel 331 and the buoy 31.

[0065] A second aspect of the present application provides a monitoring method for a monitoring device of a buoy gate, which adopts the monitoring device of the buoy gate of the first aspect and specifically includes the following steps:

[0066] When the water level rises, the float 31 moves upward under the action of buoyancy, driving the door plate 331 to rotate closer to the gate, and finally completely close the gate. At this time, the first limit switch 333 is triggered by the contact seat 335. The controller receives the gate closure signal from the first limit switch 333 and controls the telescopic motor 332 to extend the clamping block and clamp it to the limit seat 334, ensuring that the door plate 331 is fixed.

[0067] When the water surface is slightly undulated due to wind or other factors, the buoy 31 can swing slightly up and down on the water surface, while the swing rod 35 swings within a part of the range of the movable seat 36 to unload the force without affecting the sealing effect of the gate and avoiding accelerated wear of parts;

[0068] When the water level drops, the buoy 31 moves down with the water surface, and the gravity of the buoy 31 drives the swing rod 35 to press the second travel switch 365 in the movable seat 36. The second travel switch 365 transmits this signal to the controller; the controller controls the telescopic motor 332 to retract the block from the limit seat 334, releasing the limit of the door panel 331; at this time, the door panel 331 rotates as the buoy 31 descends, gradually moving away from the gate, and realizing the automatic opening of the gate.

[0069] The third signal input terminal of the controller receives active control instructions to control the extension and retraction of the push rod motor 325 and change the angle between the door panel 331 and the float 31; after adjustment, a higher or lower water level can be set to trigger the opening or closing of the gate.

[0070] It should also be understood that when the angle between the swing arm 35, the steering seat 32 and the door plate 331 in the present device is small, only a lower water level is required to enable the door plate to close the gate. When the angle between the swing arm 35, the steering seat 32 and the door plate 331 in the present device is large, a higher water level is required to enable the door plate to close the gate. For details, please refer to Figure 6 (smaller angle) and Figure 8 (Larger angle) Different angle states between the swing rod 35, the steering seat 32 and the door panel 331.

[0071] When the buoy 31 is completely above the water surface, but the door panel 331 is difficult to open due to sludge blockage, the water immersion sensor 43 detects that the buoy 31 is suspended above the water surface, triggering the pump body 41 to start; the pump body 41 sprays air or water to the lower half of the door panel 331 through the connected hose 42 to remove the sludge; after the water immersion sensor 43 detects that the buoy 31 has re-entered the water, the pump body 41 is shut down and the equipment resumes normal operation.

[0072] The above are merely embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
