Description

Technical Field

[0001] This utility model relates to water conservancy equipment, and more particularly to a novel sluice gate. Background Technology

[0002] In existing technologies, river water level regulation methods include not only lift gates, but also rubber dams, hydraulic dams, and flap dams, each with its own advantages and disadvantages. Lift gates, hydraulic dams, and rubber dams can adjust their height during use to regulate water level and flow rate. Flap dams, however, can only be set at a specific water level; once the water level is exceeded, they are forcibly opened by water pressure and only close automatically after the water level returns to the predetermined value. Lift gates, to effectively resist water pressure, must be very heavy, making the lifting process difficult and requiring high-power motors or other mechanisms. However, they can adjust the lifting height as needed, thus infinitely regulating the water flow path. Their disadvantages include high cost and high power and energy consumption during the lifting process. Hydraulic dams use hydraulic mechanisms to adjust the dam height, and some hydraulic dams can also adjust the angle of the dam plates to regulate the water flow path. Their disadvantages also include high cost, the need to move the dam using hydraulic devices during adjustment, and high power and energy consumption during the adjustment process. Rubber dams are a type of overflow dam, which... Inflatable dams regulate the height of the dam body, thereby adjusting the overflow water level and water flow path. Their advantages include low cost, but disadvantages include the inability to adjust only the dam height and the susceptibility of rubber dams to damage. Flip-plate dams regulate water levels by automatically opening when the water level reaches a predetermined height and automatically closing when the water level drops to a predetermined height. However, these dams only exist in two states: open and closed, offering little adjustment over the water flow path, and once opened, they can only close after the water level drops to a fixed position. Magnetic flip-plate dams are an improved version of flip-plate dams, using magnetism as the water level adjustment mechanism. However, they also only exist in two states: open and closed, offering little adjustment over the water flow path, and once opened, they can only close after the water level drops to a fixed position. Therefore, a new type of sluice gate that can regulate water levels, has a simple structure, is easy to install, has low cost and maintenance, is widely applicable, convenient to operate, energy-efficient, and highly reliable, represents the current research direction for alternative products. Utility Model Content

[0003] To address the various problems in the prior art, this utility model provides a novel sluice gate.

[0004] A novel sluice gate is used to be installed on the outer wall of the water outlet side of the main dam body. It includes: two water-retaining plate slide rails, a water-retaining plate, and a water-retaining plate lifting device. The two water-retaining plate slide rails are respectively installed on the outer wall of the main dam body on the left and right sides of the water outlet. The water-retaining plate slide rails are both installed vertically and are parallel. Each side of the water-retaining plate is provided with a limiting device that cooperates with and slides with the water-retaining plate slide rail. The lifting component of the water-retaining plate lifting device is connected to the water-retaining plate, and the fixing component of the water-retaining plate lifting device is fixed to the main dam body.

[0005] Furthermore, in the aforementioned novel sluice gate: the slide rail is elongated and has an I-shaped cross-section, meaning the upper and lower plates are parallel, and the connecting plate in the middle is fixedly connected to both the upper and lower plates; the water baffle has an L-shaped fold on each of its left and right sides, with both L-shaped folds on the same side of the water baffle. The L-shaped fold on the left side of the water baffle forms a U-shaped space opening to the right, and the L-shaped fold on the right side of the water baffle forms a U-shaped space opening to the left. A limiting strip is provided on each of the left and right side plates on the same side of the water baffle. The dimension between the limiting strip and the vertical edge of the L-shaped fold on the same side is the width of the lower plate of the slide rail, and the dimension between the limiting strip and the horizontal edge of the L-shaped fold on the same side is the thickness of the lower plate of the slide rail. The left and right limiting strips are parallel to the axes of the left and right U-shaped spaces. The lower plate of the corresponding slide rail is fitted into the corresponding U-shaped space.

[0006] Furthermore, the novel sluice gate also includes two sets of sliding rail hinges and two sets of sliding rail electromagnets; each of the two water-retaining plate sliding rails has a sliding rail hinge at its top, the fixing part of the sliding rail hinge is installed on the outer wall of the main dam body, and the rotating and moving part of the sliding rail hinge is installed at the top of the water-retaining plate sliding rail. When the sliding rail hinge is open, the sliding rail rotates around the sliding rail hinge and lifts away from the main dam body; when the sliding rail hinge is closed, the sliding rail rotates around the sliding rail hinge and falls close to the main dam body; a sliding rail electromagnet is installed on the main dam body at the position where the bottom of the two water-retaining plate sliding rails falls close to each other; when the sliding rail hinge is closed, the water-retaining plate sliding rail presses the water-retaining plate against the outer wall of the main dam body, and a set of sliding rail electromagnets is installed at the bottom of the water-retaining plate sliding rail corresponding to the position against the outer wall of the main dam body when the sliding rail hinge is closed.

[0007] Furthermore, in the aforementioned novel sluice gate, the water-retaining plate lifting device includes a water-receiving bucket, a water-receiving bucket slide rail, a fixed pulley, and a steel cable. The water-receiving bucket is used to collect water leaking from the main dam's water passage. A drainage hole is provided at the bottom or lower part of the side wall of the water-receiving bucket, and an electrically controlled drainage valve is installed on the drainage hole. One end of the steel cable is connected to the handle of the water-receiving bucket, and the other end of the steel cable is connected and fixed to the upper end of the water-retaining plate. The middle part of the steel cable is wound around the rotating device of the fixed pulley, and the fixed part of the fixed pulley is fixedly installed on the outer wall of the main dam. When the electrically controlled drainage valve is closed, the weight of the water-receiving bucket increases as it continuously collects water, causing the water-receiving bucket to descend. The water-receiving bucket pulls the steel cable, and the steel cable, wound around the fixed pulley, pulls the water-retaining plate at the other end to rise relatively. When the electrically controlled drainage valve is opened, the water in the water-receiving bucket is discharged, reducing its weight. The steel cable is pulled by the gravity of the water-retaining plate, causing the water-retaining plate to descend, and the water-receiving bucket is pulled up.

[0008] A slider is fixedly connected to the outer wall of the water receiving bucket, and the slider is slidably engaged in the water receiving bucket slide rail, which is vertically installed on the outer wall of the main dam. The descent or elevation of the water receiving bucket is achieved by sliding along the water receiving bucket slide rail.

[0009] The slider has a T-shaped structure. The free end of the vertical rod in the T-shaped structure is fixed to the outer wall of the water receiving bucket, and the two ends of the horizontal rod in the T-shaped structure are respectively fixed to the axle of a roller.

[0010] The water receiving bucket slide rail has a concave cross-section and is semi-closed. On each side of the concave opening of the slide rail, there is an inwardly rolled elongated limiting plate, with the two plates facing back-to-back. Each limiting plate and the corresponding side of the water receiving bucket slide rail form a limiting groove in the elongated space. The two rollers of the slider are respectively installed and limited within the limiting grooves on their respective sides. The rollers roll within the grooves, causing the slider to move axially along the water receiving bucket slide rail. The gap between the two grooves is used to limit the vertical rod in the T-shaped structure of the slider. The steel cable is parallel to the water receiving bucket slide rail.

[0011] Furthermore, in the aforementioned new type of sluice gate, the water receiving bucket and the water receiving bucket slide rail are arranged below the water baffle; one side of the water receiving bucket is flat, and the cross-section of the water receiving bucket is D-shaped.

[0012] Furthermore, the novel sluice gate also includes an automated electrical control system, which includes a data processor, a first intermediate relay, an upstream water level sensor group, a first limit switch, a second limit switch, and a third limit switch.

[0013] The signal output terminals of the first limit switch, the second limit switch, and the third limit switch are respectively connected to the first limit switch signal input terminal, the second limit switch signal input terminal, and the third limit switch signal input terminal of the data processor.

[0014] The sluice gate opening signal output terminal of the data processor is connected in series with the coil of the first intermediate relay and then grounded. The normally closed contact of the first intermediate relay is connected between the power supply of the slide rail electromagnet and the slide rail electromagnet. When there is no signal output from the sluice gate opening signal output terminal of the data processor, the slide rail electromagnet is energized and the corresponding slide rail electromagnet attracts the corresponding slide rail. When the sluice gate opening signal output terminal of the data processor outputs a control signal, the coil of the first intermediate relay is energized, the normally closed contact of the first intermediate relay is opened, the slide rail electromagnet is de-energized, and the corresponding slide rail electromagnet releases the corresponding slide rail.

[0015] The data processor's water tank drainage control signal output terminal is connected to the control terminal of the water tank's electrically controlled drainage valve. When the data processor's sluice gate opening signal output terminal outputs a signal, the data processor's water tank drainage control signal output terminal outputs an electrical signal to the water tank's electrically controlled drainage valve, reducing the weight of the water tank during drainage until the upward pulling force on the baffle plate is reduced to a threshold. The baffle plate then slides down the baffle plate slide rail under its own weight, gradually covering the water passage hole. When the data processor's water tank drainage control signal output terminal has no signal output, the water tank's electrically controlled drainage valve is de-energized, and the weight of the water tank increases until it reaches a weight threshold, pulling the baffle plate upward along the baffle plate slide rail.

[0016] The first limit switch is located on the main dam body next to the electromagnet, and the sensing component of the first limit switch faces the slide rail; when the slide rail and the slide rail electromagnet are attracted, the first limit switch is in the open state.

[0017] The slide rail lifts upward away from the sensing component of the first limit switch after leaving the main dam body. The signal output terminal of the first limit switch outputs a signal to the first limit switch signal input terminal of the data processor.

[0018] Both the second and third limit switches are mounted on the slide rail: the second limit switch is located on the slide rail directly opposite the upper limit feedback range of the water passage hole, which extends from the upper edge of the water passage hole to 30cm above it; the third limit switch is located on the slide rail directly opposite the lower limit feedback range of the water passage hole, which extends from the lower edge of the water passage hole to 30cm below it; the sensing element of the second limit switch is lower than the lower edge of the baffle when it is raised to its full position, and the sensing element of the third limit switch is directly opposite the lower side of the baffle when it is lowered to its full position; the vertical distance between the horizontal lines of the second and third limit switches is less than or equal to the height of the baffle; when the baffle is raised to its full position, the sensing elements of both the second and third limit switches are not obstructed, and both switches are in an open state and do not emit signals; when the baffle is lowered to its full position, the sensing element of the second limit switch is directly opposite the upper side of the baffle. The sensing component of the third limit switch is positioned directly opposite the lower end of the baffle plate. The second and third limit switches send signals to the second and third limit switch signal input terminals of the data processor, respectively. During the rise or fall of the baffle plate, the sensing component of the second limit switch is blocked by the baffle plate, while the sensing component of the third limit switch is not blocked by the baffle plate. The second limit switch outputs a signal to the second limit switch signal input terminal of the data processor, while the signal output terminal of the third limit switch does not send a signal.

[0019] The upstream water level sensor group of the sluice gate includes two upstream water level sensors: a first upstream water level sensor and a second upstream water level sensor. The height of each upstream water level sensor is set such that the first upstream water level sensor is lower than the second upstream water level sensor. The signal output terminals of the first and second upstream water level sensors are respectively connected to the first and second water level signal input terminals of the data processor. The upstream water level sensor group is located 1.5 meters upstream of the sluice gate. When the water level at the sensor group is lower than the location of the first upstream water level sensor, all water level sensors have no signal, indicating a "low" water level. When the water level at the sensor group is higher than the location of the first upstream water level sensor but lower than the location of the second upstream water level sensor, only the first upstream water level sensor has a signal, while the second upstream water level sensor has no signal, indicating a "medium" water level. When the water level at the sensor group is higher than the location of the second upstream water level sensor, both the first and second upstream water level sensors have signals, indicating a "high" water level.

[0020] Furthermore, the novel sluice gate also includes a remote communication device, a remote host computer, and a local voice alarm. The remote host computer includes a mobile phone alarm signal output device and an intelligent voice broadcast speaker. The remote host computer communicates with the data processor through the remote communication device, and the data input / output terminal of the remote communication device is connected to the remote data input / output terminal of the data processor. The remote data input / output terminal of the data processor includes a host computer command receiving interface, a host computer programming data transmission interface, a data processor data acquisition upload interface, and a data processor alarm signal upload interface. The local alarm signal output terminal of the data processor is connected to the local voice alarm.

[0021] Furthermore, the novel sluice gate also includes an upstream flow velocity sensor, which is located 5 to 10 meters upstream of the sluice gate; the signal output terminal of the upstream flow velocity sensor is connected to the upstream flow velocity sensor signal input terminal of the data processor.

[0022] Furthermore, the novel sluice gate also includes two sets of sliding rail hinges and two sets of sliding rail clamping devices; each of the two water-retaining plate sliding rails has a sliding rail hinge at its top. The fixing parts of the sliding rail hinges are installed on the outer wall of the main dam body, and the rotating and moving parts of the sliding rail hinges are installed at the top of the water-retaining plate sliding rails. When the sliding rail hinges are open, the sliding rails rotate around the sliding rail hinges and lift away from the main dam body; when the sliding rail hinges are closed, the sliding rails rotate vertically around the sliding rail hinges and fall close to the main dam body. The two sets of sliding rail clamping devices have the same structure and are symmetrically arranged. One set of sliding rail clamping devices includes: a clamping lever, a set of movable joints, a set of clamping electromagnets, and a spring locking tongue. The limiting device and movable joint include a first and a second fixing mechanism arranged face-to-face, and a movable joint disposed between the two fixing mechanisms. The first fixing mechanism is fixed to the clamping lever, and the second fixing mechanism is fixed to the slide rail. The axes of the two clamping levers are arranged horizontally. Taking the movable joint as a reference point, the part of the clamping lever between the two slide rails is the inner side, and the part outside the two slide rails is the outer side of the clamping lever. The inner length of the clamping lever is longer than the outer length. In the clamping state, a clamping electromagnet is set at a corresponding position close to the main dam body on the inner end of the clamping lever. The inner end of the clamping lever is made of magnetic material. A spring-locking tongue limiting device is installed at the corresponding position of the outer end of the clamping lever, close to the main dam body. The spring-locking tongue limiting device includes a fixed locking body and a spring-locking tongue. The fixed locking body is fixed to the main dam body, and the spring-locking tongue is elastically mounted on the fixed locking body. The extension and retraction direction of the spring-locking tongue is parallel to the main dam body. The side of the spring-locking tongue facing the main dam body is a flat plane, and the other side of the spring-locking tongue facing away from the main dam body is an inclined plane that gradually slopes downwards towards the main dam body from the fixed locking body to the far end. In the clamping state, the outer end of the clamping lever is restricted between the plane of the spring-locking tongue and the main dam body. The inner end of the lever is attracted to the electromagnet; at this time, the clamping lever presses the slide rail against the main dam body; when the clamping electromagnet is de-energized, the inner end of the clamping lever is released, and the baffle plate and the slide rail are pushed upward by the water flow around the slide rail hinge. The bottom of the baffle plate and the slide rail move away from the main dam body; the clamping lever and the slide rail move away from the main dam body. Then the spring lock tongue prevents the outer end of the clamping lever from lifting, and the clamping lever rotates around the movable joint until it rotates to a sufficient angle. After that, the clamping lever slides off the spring lock tongue and enters the free state.

[0023] When returning from the released state to the pressed state, the pressing lever gradually approaches the main dam body under the action of the slide rail. The outer end of the pressing lever presses against the inclined surface of the spring lock tongue, compressing the spring lock tongue until it retracts into the fixed lock body. At the same time, the inner end of the pressing lever approaches the pressing electromagnet. After the pressing electromagnet is energized, the inner end of the pressing lever is attracted to the pressing electromagnet.

[0024] The novel sluice gate provided by this utility model is convenient and efficient to operate when adjusting the water level, and does not require manual on-site operation during normal operation, which greatly protects the personal safety of maintenance personnel; it provides timely warnings remotely and on-site when the water level exceeds the set value; it has the advantages of wide applicability, simple structure, easy installation, low cost and maintenance, energy saving during operation, and high reliability.

[0029] This utility model provides a novel sluice gate, which is installed on the outer wall of the water outlet side of the main dam body. It adopts an upper suspension structure, uses magnetic force for locking, and utilizes the gravity of the water flow to automatically reset the dam gate. Figure 1A , Figure 1B These are a front structural diagram and a side sectional view of the new type of sluice gate. Figure 1A and Figure 1B All labels are explained as follows: Label 1 is the main dam body, Label 2 is the fixed pulley, Label 3 is the slide rail hinge, Label 4 is the water-retaining plate slide rail, Label 5 is the water-retaining plate, Label 6 is the water passage hole, Label 7 is the slide rail electromagnet, Label 8 is the water receiving bucket, Label 9 is the water receiving bucket slide rail, and Label 10 is the steel cable.

[0030] The new type of sluice gate includes two water-retaining slide rails (the two water-retaining slide rails are symmetrically arranged on the left and right sides in the figure, and only one water-retaining slide rail is marked, numbered 4), one water-retaining plate 5, and a set of water-retaining plate lifting device; the two water-retaining slide rails are respectively installed on the outer wall of the main dam body 1 on the left and right sides of the water passage 6. The water passage 6 is shown in the figure with a dashed line because it is blocked by the water-retaining plate 5; the two water-retaining slide rails are parallel and installed vertically, and the water-retaining plate 5 is set between the two slide rails, forming an upper suspension structure together with the slide rails.

[0031] Figure 2The diagram shown is an enlarged view of the installation structure of the baffle slide rail and the baffle plate. Each side of the baffle plate 5 is equipped with a limiting device that engages and slides with the baffle slide rail, allowing the baffle plate to slide along the slide rail. The baffle slide rail 4 is elongated, with an I-shaped or horizontally placed H-shaped cross-section. The baffle plate 5 has an L-shaped folded edge on each side, forming a nested structure with a certain gap between it and the slide rail 4. Here, the area between the two slide rails 4 is considered the inner side, and the area outside the two slide rails 4 is considered the outer side. The L-shaped folded edge is located outside the slide rail 4. On the side, at appropriate positions on the inner side of both slide rails 4, baffles or limiting strips are provided to prevent the nested structure from falling out; the baffle 5 can slide along the slide rail 4, but will not detach from the slide rail during the sliding process; the baffle slide rail 4 can also be designed in other forms besides this shape, such as Z-shaped, or the slide rail can be designed as a square solid steel strip, or the slide rail can be designed as a rectangular hollow steel strip. Correspondingly, the L-shaped folded edge on the side of the baffle 5 used for enclosure and the baffles or limiting strips on both sides can be matched with the corresponding slide rail to play a limiting role.

[0032] The novel sluice gate also includes two sets of sliding rail hinges 3 and two sets of sliding rail electromagnets 7; each of the two water-retaining plate sliding rails 4 has a sliding rail hinge 3 at its top and a sliding rail electromagnet 7 at its bottom; the fixing parts of the sliding rail hinges 3 are installed on the outer wall of the main dam body 1, and the rotating and moving parts of the sliding rail hinges 3 are installed on the top of the water-retaining plate sliding rails 4. When the sliding rail hinges 3 are open, the sliding rails 4 rotate around the sliding rail hinges 3 and lift away from the main dam body 1; when the sliding rail hinges 3 are closed, the sliding rails 4 rotate around the sliding rail hinges 3 and fall back close to the main dam body 1; the sliding rail hinges are in the closed state. The sliding rail electromagnet 7 provides magnetic force to keep it in a fitted state, while the baffle plate sliding rail 4 presses the baffle plate 5 against the outer wall of the main dam body 1. Each set of sliding rail electromagnets can include only one electromagnet, which can be of a fixed specification or an adjustable electromagnet. The adjustable electromagnet can adjust the magnetic force by adjusting the current to achieve different sluice gate opening water levels. Each set of sliding rail electromagnets can also be a combination of two or more electromagnets. Opening different numbers of electromagnets corresponds to different sluice gate opening water levels, which can achieve gradient adjustment.

[0033] The lifting component of the water-retaining plate lifting device is connected to the water-retaining plate 5, and the fixing component of the water-retaining plate lifting device is fixed to the main dam body. The water-retaining plate lifting device includes a water receiving bucket 8, a water receiving bucket slide rail 9, a fixed pulley 2, and a steel cable 10. The water receiving bucket 8 is used to collect water leaking from the water passage 6 of the main dam body. A drainage hole is provided at the bottom or lower part of the side wall of the water receiving bucket 8, and an electrically controlled drainage valve is installed on the drainage hole. The steel cable 10 is the lifting component. One end of the steel cable 10 is connected to the handle of the water receiving bucket 8, and the other end of the steel cable 10 is connected and fixed to the upper end of the water-retaining plate 5. The intermediate part is wound around the rotating device of the fixed pulley 2, and the fixed part of the fixed pulley 2 is fixedly installed on the outer wall of the main dam body 1. The fixed part of the fixed pulley 2 is the fixed part of the water baffle lifting device. When the electric control drain valve is energized and closed, the water receiving bucket 8 continues to receive water and the weight increases. The water receiving bucket 8 descends and pulls the steel cable 10. The steel cable 10, around the fixed pulley 2, pulls the water baffle 5 at the other end to rise relatively. When the electric control drain valve is de-energized, the valve opens. At this time, the water in the water receiving bucket 8 is discharged and the weight decreases. The steel cable 10 is pulled by the gravity of the water baffle 5, the water baffle 5 descends, and the water receiving bucket 8 is pulled up.

[0034] A slider is fixedly connected to the outer wall of the water receiving bucket 8. This slider is slidably engaged within the water receiving bucket slide rail 9, which is vertically installed on the outer wall of the main dam body 1. The descent or elevation of the water receiving bucket 8 is achieved by sliding along the water receiving bucket slide rail 9. Figure 3 The enlarged view of the slider structure shown indicates that the slider is a T-shaped structure. The free end of the vertical rod in the T-shaped structure is fixed to the outer wall of the water receiving bucket 8. The two ends of the horizontal rod in the T-shaped structure are respectively fixed to the axis of a roller. The rollers rotate around the axis, causing the slider to slide along the axis of the water receiving bucket slide rail 9. The cross-section of the water receiving bucket slide rail 9 is U-shaped and semi-closed. At the openings on both sides of the U-shaped water receiving bucket slide rail 9, there is an L-shaped long strip limiting plate with an inwardly rolled edge. The two long strip limiting plates are arranged back to back. Each long strip limiting plate and the corresponding side of the water receiving bucket slide rail form a limiting receiving groove in the long strip space. The two rollers of the slider are respectively installed and limited in the limiting receiving grooves on the corresponding sides. The rollers roll in the receiving grooves, causing the slider to move along the axis of the water receiving bucket slide rail 9. The gap between the two receiving grooves is used to limit the vertical rod in the T-shaped structure of the slider. The steel cable 10 is parallel to the water receiving bucket slide rail 9. The water receiving bucket 8 and the water receiving bucket slide rail 9 are located below the water baffle 5; one side of the water receiving bucket is flat, and the cross-section of the water receiving bucket is D-shaped. The water receiving bucket can also be designed as a cuboid or a cube. The water receiving bucket can also be any shape.

[0035] In another embodiment, a water inlet pipe can be installed on the main dam body on one side of the water inlet hole, and a water receiving bucket and a water receiving bucket slide rail can be installed on the main dam body below the water inlet pipe.

[0036] The novel sluice gate also includes an automated electrical control system, which includes a data processor, a first intermediate relay, an upstream water level sensor group, a first limit switch 15c, a second limit switch 15a, and a third limit switch 15b; in this embodiment, the data processor is a PLC; the signal output terminals of the first limit switch 15c, the second limit switch 15a, and the third limit switch 15b are respectively connected to the first limit switch 15c signal input terminal, the second limit switch 15a signal input terminal, and the third limit switch signal input terminal of the PLC;

[0037] The PLC's sluice gate opening signal output terminal is connected in series with the coil of the first intermediate relay and then grounded. The normally closed contact of the first intermediate relay is connected between the power supply of the slide rail electromagnet and the slide rail electromagnet. When the PLC's sluice gate opening signal output terminal has no signal output, the slide rail electromagnet is energized, and the corresponding slide rail electromagnet attracts the corresponding slide rail. When the PLC's sluice gate opening signal output terminal outputs a control signal, the coil of the first intermediate relay is energized, the normally closed contact of the first intermediate relay is opened, the slide rail electromagnet is de-energized, and the corresponding slide rail electromagnet releases the corresponding slide rail.

[0038] The PLC's water tank drainage control signal output terminal is connected to the control terminal of the water tank's electrically controlled drainage valve. When the PLC's water gate opening signal output terminal outputs a signal, the PLC's water tank drainage control signal output terminal outputs an electrical signal to the water tank's electrically controlled drainage valve, reducing the weight of the water tank during drainage until the upward pulling force on the baffle plate is reduced to a threshold. The baffle plate then slides down the baffle plate slide rail under its own weight, gradually covering the water passage hole. When the PLC's water tank drainage control signal output terminal has no signal output, the water tank's electrically controlled drainage valve is de-energized, and the weight of the water tank increases until it reaches a weight threshold, pulling the baffle plate upward along the baffle plate slide rail.

[0039] The first limit switch 15c is installed on the main dam body next to the slide rail electromagnet, and the sensing component of the first limit switch 15c faces the slide rail. When the slide rail and the slide rail electromagnet are attracted, the first limit switch 15c is in the open state. When the slide rail leaves the main dam body and lifts up away from the sensing component of the first limit switch 15c, the signal output terminal of the first limit switch 15c outputs a signal to the first limit switch 15c signal input terminal of the PLC.

[0040] Both the second limit switch 15a and the third limit switch 15b are mounted on the slide rail. The second limit switch 15a is located on the slide rail directly opposite the upper limit feedback range of the water passage hole. The upper limit feedback range is the area from the upper edge to 30cm above the upper edge, preferably at the slide rail position directly opposite the horizontal line of the range 10-20cm above the upper edge of the water passage hole, such as the slide rail positions corresponding to the horizontal lines of 10cm, 12cm, and 15cm above the upper edge of the water passage hole. The third limit switch 15b is located on the slide rail directly opposite the lower limit feedback range of the water passage hole. The lower limit feedback range is the area from the lower edge to 30cm above the lower edge, preferably at the slide rail position corresponding to the horizontal line of the area 10-20cm below the lower edge of the water hole, such as the slide rail positions corresponding to the horizontal lines of 10cm, 12cm, and 15cm below the lower edge of the water hole; the sensing element of the second limit switch 15a is located at the lower edge of the baffle when the baffle is raised to its full position, and the sensing element of the third limit switch 15b is directly opposite the lower end side of the baffle when the baffle is lowered to its full position; the vertical distance between the horizontal lines of the second limit switch 15a and the third limit switch 15b is less than or equal to the height of the baffle; when the baffle is raised to its full position, the sensing elements of the second limit switch 15a and the third limit switch 15b are not obstructed, and both the second limit switch 15a and the third limit switch 15b are in an open state and do not emit signals; when the baffle is lowered to its full position, the sensing element of the second limit switch 15a is directly opposite the upper end side of the baffle at this time. The sensing element of the third limit switch 15b is directly opposite the lower end side of the baffle plate. The second limit switch 15a and the third limit switch 15b respectively send signals to the second and third limit switch signal input terminals of the PLC. During the process of the baffle plate rising or falling, the sensing element of the second limit switch 15a is blocked by the baffle plate, while the sensing element of the third limit switch 15b is not blocked by the baffle plate. The second limit switch 15a outputs a signal to the second limit switch signal input terminal of the PLC, while the signal output terminal of the third limit switch 15b does not send a signal. The aforementioned limit switches are waterproof limit switches, such as lever type or magnetic induction type switches.

[0041] The upstream water level sensor group of the sluice gate includes two upstream water level sensors: a first upstream water level sensor and a second upstream water level sensor. The height of each upstream water level sensor is set such that the first upstream water level sensor is lower than the second upstream water level sensor. The signal output terminals of the first and second upstream water level sensors are respectively connected to the first and second water level signal input terminals of the PLC. The upstream water level sensor group of the sluice gate is set at a distance of 1.5 to 5 meters upstream of the sluice gate.

[0042] The novel sluice gate also includes a remote communication device, a remote host computer, and a local voice alarm. The remote host computer includes a mobile phone alarm signal output device and an intelligent voice broadcast speaker. The remote host computer communicates with the data processor through the remote communication device, and the data input / output terminals of the remote communication device are connected to the remote data input / output terminals of the data processor. The remote data input / output terminals of the data processor include a host computer command receiving interface, a host computer programming data transmission interface, a data processor data acquisition upload interface, and a data processor alarm signal upload interface. The local alarm signal output terminal of the data processor is connected to the local voice alarm. The remote communication device is a wireless communication module.

[0043] Based on the aforementioned control process of the new type of sluice gate, which sets three different water levels—"high," "medium," and "low"—the process includes the following steps:

[0044] Step 1) The system performs a periodic self-test. During a self-test, the remote host computer sends a self-test signal to the data processor via the remote communication device. After the data processor completes the self-test normally, it uploads a normal self-test return signal via the remote communication device. If the remote host computer determines that both the remote communication device and the data processor are working normally, it proceeds to Step 2). If the remote host computer does not receive the self-test return signal from the remote communication device, then the remote communication device or the data processor has malfunctioned. The remote host computer sends an alarm message "The remote communication device or data processor has malfunctioned" to the administrator's mobile phone via the mobile phone alarm signal output device. At the same time, the remote host computer plays the voice signal "The remote communication device or data processor has malfunctioned" repeatedly through the intelligent voice broadcast speaker.

[0045] Step 2) The data processor determines whether there is a signal input at the first and second water level signal input terminals upstream:

[0046] If the data processor determines that both the first and second water level signal input terminals upstream have received signals, proceed to step 2-1).

[0047] If the data processor determines that a signal has been received at the first upstream signal input terminal, but no signal has been received at the second upstream water level signal input terminal, proceed to step 2-2).

[0048] If the data processor determines that there is no signal input at either the first or second water level signal input terminal upstream, proceed to step 2-3).

[0049] If the data processor determines that the signals from the first and second water level signal input terminals upstream do not fall into the above three categories, the data processor will upload a signal to the host computer via its remote data input / output terminal: "Water level sensor malfunction" and report a fault alarm signal to the host computer.

[0050] Step 2-1): The data processor determines that the water level upstream of the sluice gate is "high" and uploads the aforementioned data acquisition signals ("both upstream low water level signal input and upstream high water level signal input have received signals") to the host computer through its remote data input / output terminal. Simultaneously, it uploads the upstream "high" water level alarm signal to the host computer's voice alarm device to broadcast a "high water level warning" voice signal. At the same time, the data processor's on-site alarm signal output terminal outputs a drive signal, driving the on-site voice alarm device to broadcast a "high water level warning upstream of the sluice gate" voice signal. Afterwards, proceed to step 3).

[0051] Step 2-2): The data processor determines that the current upstream water level of the sluice gate is "medium". The data processor uploads the data acquisition signal to the host computer through the remote data input / output terminal: "The upstream low water level signal input terminal received a signal, while the upstream high water level signal input terminal had no signal input"; return to step 1).

[0052] Steps 2-3): The data processor determines that the current upstream water level of the sluice gate is "low". The data processor uploads the data acquisition signal "No signal input at both the upstream low water level signal input terminal and the upstream high water level signal input terminal" to the host computer through the remote data input / output terminal. At the same time, it uploads the upstream "low" water level alarm signal to the host computer's voice alarm device to broadcast the "low water level warning" voice signal. Simultaneously, the data processor's on-site alarm signal output terminal outputs a drive signal to drive the on-site voice alarm device to broadcast the "sluice gate upstream low water level warning" voice signal. After that, proceed to step 8).

[0053] Step 3): The data processor checks if there is a signal input to the first limit switch. If there is a signal input to the first limit switch, the slide rail is in close contact with the main dam body. The data processor outputs a "sluice gate open" signal at the sluice gate opening signal output terminal and a "drainage valve closed" signal at the water receiving bucket drainage control signal output terminal. The power control terminal of the slide rail electromagnet is de-energized. Subsequently, the water flow thrust pushes the baffle, causing the baffle plate and slide rail to lift. The water passage opens, and the flood discharge plate slides upward along the baffle plate slide rail. Then, proceed to Step 4). If there is no signal input to the first limit switch, proceed directly to Step 4.

[0054] Step 4) The data processor starts timing, i.e., timing 1, and simultaneously checks every 1 second whether there is a signal input at the first limit switch input terminal: If there is a signal input at the first limit switch input terminal and it is still within the first timing cycle, then the timing continues and the check is repeated every second; if there is a signal input at the first limit switch and the first timing cycle has ended, then the signal "slide rail release timeout or first limit switch failure" is uploaded to the host computer through the remote data input / output terminal, and a fault alarm signal is reported to the host computer; if there is no signal input at the first limit switch and timing 1 has not exceeded the set time, then the signal "sluice gate has been opened" is uploaded to the host computer through the remote data input / output terminal, and then proceeds to Step 5).

[0055] Step 5) The data processor starts timing, i.e., timing 2, and simultaneously checks the third limit switch for signal input every 1 second and makes a judgment: If the third limit switch has a signal input, the baffle is in the lowered position, and timing 2 has not exceeded the set time, so the timing continues and the check is repeated every second; if the third limit switch has a signal input and timing 2 exceeds the set time, the signal "baffle rising fault" is uploaded to the host computer through the remote data input / output terminal, and a fault alarm signal is reported to the host computer; if the third limit switch has no signal input and timing 2 has not exceeded the set time, the signal "baffle is rising" is uploaded to the host computer through the remote data input / output terminal, and then proceeds to step 6).

[0056] Step 6) The data processor starts timing, i.e., timing 3, and simultaneously checks the second limit switch for signal input every 1 second and makes a judgment: If the second limit switch has a signal input and timing 3 has not exceeded the set time, then the timing continues and the check is repeated every second; if the second limit switch has a signal input and timing 3 has exceeded the set time, then the signal "Water baffle not raised to the position on time" is uploaded to the host computer through the remote data input / output terminal, and a fault alarm signal is reported to the host computer; if the second limit switch has no signal input and timing 3 has not exceeded the set time, then the signal "Water baffle raised to the position" is uploaded to the host computer through the remote data input / output terminal, and then proceeds to Step 7).

[0057] Step 7) The data processor starts timing, i.e., timing 4, and simultaneously checks the first limit switch for signal input every 1 second and makes a judgment: If the first limit switch has no signal input, the slide rail is not closed, and timing 4 has not exceeded the set time, so the timing continues and the check is repeated every second; if the first limit switch has a signal input and timing 4 has exceeded the set time, the signal "Slide rail not reset on time" is uploaded to the host computer through the remote data input / output terminal, and a fault alarm signal is reported to the host computer; if the first limit switch has a signal input and timing 4 has not exceeded the set time, the signal "Sluice gate is fully open and meets the closing conditions" is uploaded to the host computer through the remote data input / output terminal, and then the process returns to step 1).

[0058] Step 8): The data processor detects whether there is a signal input at the first limit switch input terminal. If there is a signal input at the first limit switch, the slide rail is in close contact with the main dam body. The data processor outputs a "sluice gate closed" signal and a "drainage valve open" signal at the sluice gate opening signal output terminal. The "sluice gate closed" signal controls the power control terminal of the slide rail electromagnet to engage, locking the slide rail onto the main dam body. The "drainage valve open" signal controls the water receiving bucket to open, allowing the water receiving bucket to start releasing water until the weight reaches the threshold. The water receiving bucket then moves upward and pulls the baffle plate down the baffle plate slide rail, gradually closing the water passage. Afterward, proceed to step 9). If there is no signal input at the first limit switch, the slide rail is not in close contact with the main dam body and cannot be closed. The data processor then uploads a signal to the host computer via the remote data input / output terminal: "The sluice gate is currently open but not reset." Afterward, return to step 1).

[0059] Step 9): The data processor starts timing, i.e., timing 5, and simultaneously checks the second limit switch for signal input every 1 second and makes a judgment: If the second limit switch has no signal input, the baffle is still in the raised position, and timing 5 has not exceeded the set time, so the timing continues and the check is repeated every second; if the second limit switch has no signal input and timing 5 has exceeded the set time, the signal "Baffle has not started to descend on time" is uploaded to the host computer through the remote data input / output terminal, and a fault alarm signal is reported to the host computer; if the second limit switch has a signal input and timing 5 has not exceeded the set time, the signal "Baffle has started to descend" is uploaded to the host computer through the remote data input / output terminal, and then proceeds to step 10).

[0060] Step 10) The data processor starts timing, i.e., timing 6, and at the same time starts checking whether there is a signal input to the third limit switch every 1 second and makes a judgment: If there is no signal input to the third limit switch and timing 6 has not exceeded the set time, then the timing continues and the check is repeated every second; if there is no signal input to the third limit switch and timing 6 has exceeded the set time, then the signal "Water baffle has not descended to the position on time" is uploaded to the host computer through the remote data input / output terminal, and a fault alarm signal is reported to the host computer; if there is a signal input to the second limit switch and timing 6 has not exceeded the set time, then the signal "Water gate is closed" is uploaded to the host computer through the remote data input / output terminal, and then the process returns to step 1).

[0061] The water level sensor can be a float-type water level sensor. When the water level drops to the specified level, the float set at the corresponding water level changes from a floating state to a suspended state, and outputs a corresponding switching signal.

[0062] This utility model also provides another embodiment of the novel sluice gate, which, in addition to the aforementioned baffle plate 5, baffle plate slide rail 4, baffle plate lifting device, and a set of slide rail hinges 3 at the upper end of each of the two baffle plate slide rails, also includes two sets of slide rail clamping devices, such as... Figure 4A , Figure 4BThe diagram shown is a front view and a side sectional view of another embodiment of the novel sluice gate: the two sets of slide rail clamping devices have the same structure and are symmetrically arranged; one set of slide rail clamping devices includes a clamping lever 12, a set of movable joints 11, a set of clamping electromagnets 7, and a spring locking tongue limiting device. The movable joint 11 includes a first and a second fixing mechanism arranged face to face, and a movable joint movably connected between the two fixing mechanisms. The first fixing mechanism is fixed to the clamping lever 12, and the second fixing mechanism is fixed to the slide rail 4; the two clamping levers 12... The axis is set horizontally; taking the movable joint 11 as a reference point, the part of the clamping lever 12 between the two slide rails is the inner side, and the part outside the two slide rails is the outer side of the clamping lever 12. The inner length of the clamping lever 12 is longer than the outer length. Preferably, the inner length of the clamping lever 12 is 2 to 5 times the outer length. In the clamping state, a set of clamping electromagnets 7 is set at the corresponding position of the inner end of the clamping lever 12 close to the main dam body. The inner end of the clamping lever 12 is made of magnetic material or magnetic material such as connecting and fixing iron blocks. A spring-locking tongue limiting device is installed at the corresponding position of the outer end of the clamping lever 12 close to the main dam body. The spring-locking tongue limiting device includes a fixed locking body 13 and a spring-locking tongue 14. The fixed locking body 13 is fixed to the main dam body, and the spring-locking tongue 14 is elastically mounted on the fixed locking body 13. The extension and retraction direction of the spring-locking tongue 14 is parallel to the surface of the main dam body. The side of the spring-locking tongue 14 facing the main dam body is a flat surface, and the other side of the spring-locking tongue 14 facing away from the main dam body is an inclined surface that gradually slopes downwards towards the main dam body from the position of the fixed locking body 13 to the distal end of the tongue tip. In the clamping state, the outer end of the clamping lever 12 is restricted to the plane of the spring-locking tongue 14 and the outer wall surface of the main dam body 1. Between the surfaces, the inner end of the clamping lever 12 is attracted to the electromagnet 7; at this time, the clamping lever 12 presses the slide rail 4 onto the main dam body 1; when the clamping electromagnet 7 is de-energized, the inner end of the clamping lever 12 is released, the baffle plate 5 and the slide rail are pushed upward by the water flow around the slide rail hinge, the bottom of the baffle plate 5 and the slide rail 4 move away from the main dam body, and the clamping lever 12 and the slide rail 4 move away from the main dam body accordingly. Then the spring lock tongue 14 prevents the outer end of the clamping lever 12 from lifting, and the clamping lever 12 rotates around the movable joint until it rotates to a sufficient angle. Then the clamping lever 12 slides off the spring lock tongue 14 and the clamping lever 12 enters the free state.

[0063] When the lever 12 returns to the clamping state from the released state, it gradually approaches the main dam body under the action of the slide rail. The outer end of the lever 12 presses against the inclined surface of the spring lock tongue 14, pressing the spring lock tongue 14 until it retracts into the fixed lock body 13. At the same time, the inner end of the lever 12 approaches the clamping electromagnet 7. After the clamping electromagnet 7 is energized, the inner end of the lever 12 is attracted to the clamping electromagnet 7.

[0064] When the slide rail is locked, the magnetic force arm of the clamping electromagnet is amplified several times by the clamping lever. For example, taking the center point of the spring latch in the popped-out state as a reference, the distance between the slide rail central axis and the center point of the latch is 0.2m, and the distance between the clamping electromagnet and the center point of the latch is 1m. At this time, the magnetic force arm of the electromagnet will be amplified by 5 times, and only 1 / 5 of the magnetic force in the first embodiment mentioned above is needed to achieve equivalent control.

[0065] The aforementioned electrically controlled drain valve for the water receiving bucket can be a solenoid valve, suitable for situations where the water flow is relatively clear, free of debris, and not prone to clogging. Since the solenoid valve can open and close at any water level, the water level in the bucket can be adjusted by controlling the valve's opening and closing, thereby regulating the speed at which the baffle plate rises and falls. Alternatively, the electrically controlled drain valve for the water receiving bucket can be configured as a miniature magnetic flap dam, also controlled by a PLC output. This miniature magnetic flap dam is suitable for situations where the water flow contains a lot of debris and is prone to clogging.

[0066] This technical solution allows for the installation of multiple water-retaining devices on a single main dam body, each of which can be independently controlled. The opening and closing of electromagnets and the magnitude of their magnetic force can be indirectly controlled via a PLC, enabling remote control of any water-retaining device. Furthermore, a remote communication module and a dedicated app can be added to allow remote control of any water-retaining device via mobile phone or other devices. This invention utilizes the adjustable magnetic force of electromagnets, achieving gate locking and opening without damage or loss after forced opening. The water flow after the sluice gate is opened serves as the power for the baffle plate to reset, allowing for repeated opening and closing of the sluice gate. Moreover, this sluice gate can be designed to open under specific water pressure (water level), with an absolutely reliable and virtually lossless opening process. This sluice gate can handle sudden water flows and situations where the water flow carries rocks or trees. Compared to ordinary lift-type sluice gates, this sluice gate can open its water passages upon power failure, with an energy-saving and reliable opening process and virtually no energy consumption during the baffle plate reset process. After the sluice gate has been open for a period of time, the water passages can be closed even if the water level at the sluice gate's location has not decreased. This sluice gate has a simple and reliable structure, requiring no high-power motors or hydraulic devices, resulting in low cost. Daily maintenance only requires operating a few electromagnets, resulting in low power consumption and minimal maintenance. This sluice gate can be integrated with other dam structures; for example, a standard lift sluice gate can be used as the main dam, with this sluice gate mounted on top. Even if a large water-retaining plate is used, this sluice gate can serve as the main dam, with a smaller version mounted on top. Each sluice gate system can be independently controlled. The total water flow can be adjusted by opening different numbers of water passages. Furthermore, the water-retaining plate lifting device can be modified to use other methods, such as waterwheels, flywheels, chains, or direct electric motor-driven lifting.

[0067] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.

4. The novel sluice gate as described in claim 3, characterized in that... The aforementioned water-receiving plate lifting device includes a water-receiving bucket, a water-receiving bucket slide rail, a fixed pulley, and a steel cable. The water-receiving bucket is used to collect water leaking from the main dam's water passages. A drain hole is provided at the bottom or lower part of the side wall of the water-receiving bucket, and an electrically controlled drain valve is installed on the drain hole. One end of the steel cable is connected to the handle of the water-receiving bucket, and the other end of the steel cable is connected and fixed to the upper end of the water-receiving plate. The middle part of the steel cable is wound around the rotating device of the fixed pulley, and the fixed part of the fixed pulley is fixedly installed on the outer wall of the main dam. When the electrically controlled drain valve is closed, the water-receiving bucket continues to collect water, increasing its weight and causing it to descend. The water-receiving bucket pulls the steel cable, and the steel cable, wound around the fixed pulley, pulls the water-receiving plate at the other end to rise relatively. When the electrically controlled drain valve is opened, the water in the water-receiving bucket is discharged, reducing its weight. The steel cable is pulled by the gravity of the water-receiving plate, causing the water-receiving plate to descend, and the water-receiving bucket is pulled up. A slider is fixedly connected to the outer wall of the water receiving bucket, and the slider is slidably engaged in the water receiving bucket slide rail, which is vertically installed on the outer wall of the main dam.

On each side of the concave opening of the slide rail, there is an inwardly rolled elongated limiting plate, with the two plates facing back-to-back. Each limiting plate and the corresponding side of the water receiving bucket slide rail form a limiting groove in the elongated space. The two rollers of the slider are respectively installed and limited within the limiting grooves on their respective sides. The rollers roll within the grooves, causing the slider to move axially along the water receiving bucket slide rail. The gap between the two grooves is used to limit the vertical rod in the T-shaped structure of the slider. The steel cable is parallel to the water receiving bucket slide rail.

5. The novel sluice gate as described in claim 4, characterized in that... The water receiving bucket and its sliding rail are located below the baffle plate; one side of the water receiving bucket is flat, and the cross-section of the water receiving bucket is D-shaped.

6. The novel sluice gate as described in claim 4 or 5, characterized in that... It also includes an automated electrical control system, which includes a data processor, a first intermediate relay, a group of upstream water level sensors for the sluice gate, a first limit switch, a second limit switch, and a third limit switch. The signal output terminals of the first limit switch, the second limit switch, and the third limit switch are respectively connected to the first limit switch signal input terminal, the second limit switch signal input terminal, and the third limit switch signal input terminal of the data processor. The sluice gate opening signal output terminal of the data processor is connected in series with the coil of the first intermediate relay and then grounded. The normally closed contact of the first intermediate relay is connected between the power supply of the slide rail electromagnet and the slide rail electromagnet. When there is no signal output from the sluice gate opening signal output terminal of the data processor, the slide rail electromagnet is energized and the corresponding slide rail electromagnet attracts the corresponding slide rail. When the sluice gate opening signal output terminal of the data processor outputs a control signal, the coil of the first intermediate relay is energized, the normally closed contact of the first intermediate relay is opened, the slide rail electromagnet is de-energized, and the corresponding slide rail electromagnet releases the corresponding slide rail. The data processor's water tank drainage control signal output terminal is connected to the control terminal of the water tank's electrically controlled drainage valve. When the data processor's sluice gate opening signal output terminal outputs a signal, the data processor's water tank drainage control signal output terminal outputs an electrical signal to the water tank's electrically controlled drainage valve, reducing the weight of the water tank during drainage until the upward pulling force on the baffle plate is reduced to a threshold. The baffle plate then slides down the baffle plate slide rail under its own weight, gradually covering the water passage hole. When the data processor's water tank drainage control signal output terminal has no signal output, the water tank's electrically controlled drainage valve is de-energized, and the weight of the water tank increases until it reaches a weight threshold, pulling the baffle plate upward along the baffle plate slide rail. The first limit switch is located on the main dam body next to the electromagnet, and the sensing component of the first limit switch faces the slide rail; when the slide rail and the slide rail electromagnet are attracted, the first limit switch is in the open state. The slide rail lifts upward away from the sensing component of the first limit switch after leaving the main dam body. The signal output terminal of the first limit switch outputs a signal to the first limit switch signal input terminal of the data processor. Both the second and third limit switches are mounted on the slide rail: the second limit switch is located on the slide rail directly opposite the upper limit feedback range of the water passage hole, which extends from the upper edge of the water passage hole to 30cm above it; the third limit switch is located on the slide rail directly opposite the lower limit feedback range of the water passage hole, which extends from the lower edge of the water passage hole to 30cm below it; the sensing element of the second limit switch is lower than the lower edge of the baffle when it is raised to its full position, and the sensing element of the third limit switch is directly opposite the lower side of the baffle when it is lowered to its full position; the vertical distance between the horizontal lines of the second and third limit switches is less than or equal to the height of the baffle; when the baffle is raised to its full position, the sensing elements of both the second and third limit switches are not obstructed, and both switches are in an open state and do not emit signals; when the baffle is lowered to its full position, the sensing element of the second limit switch is directly opposite the upper side of the baffle. The sensing component of the third limit switch is positioned directly opposite the lower end of the baffle plate. The second and third limit switches send signals to the second and third limit switch signal input terminals of the data processor, respectively. During the rise or fall of the baffle plate, the sensing component of the second limit switch is blocked by the baffle plate, while the sensing component of the third limit switch is not blocked by the baffle plate. The second limit switch outputs a signal to the second limit switch signal input terminal of the data processor, while the signal output terminal of the third limit switch does not send a signal. The upstream water level sensor group of the sluice gate includes two upstream water level sensors: a first upstream water level sensor and a second upstream water level sensor. The height of each upstream water level sensor is set such that the first upstream water level sensor is lower than the second upstream water level sensor. The signal output terminals of the first and second upstream water level sensors are respectively connected to the first and second water level signal input terminals of the data processor. The upstream water level sensor group is located 1.5 meters upstream of the sluice gate. When the water level at the sensor group is lower than the location of the first upstream water level sensor, all water level sensors have no signal, indicating a "low" water level. When the water level at the sensor group is higher than the location of the first upstream water level sensor but lower than the location of the second upstream water level sensor, only the first upstream water level sensor has a signal, while the second upstream water level sensor has no signal, indicating a "medium" water level. When the water level at the sensor group is higher than the location of the second upstream water level sensor, both the first and second upstream water level sensors have signals, indicating a "high" water level.

7. The novel sluice gate as described in claim 6, characterized in that, It also includes a remote communication device, a remote host computer, and an on-site voice alarm. The remote host computer includes a mobile phone alarm signal output device and an intelligent voice broadcast speaker. The remote host computer communicates with the data processor through the remote communication device, and the data input / output terminals of the remote communication device are connected to the remote data input / output terminals of the data processor. The remote data input / output terminals of the data processor include a host computer command receiving interface, a host computer programming data transmission interface, a data processor data acquisition upload interface, and a data processor alarm signal upload interface. The on-site alarm signal output terminal of the data processor is connected to the on-site voice alarm.

8. The novel sluice gate as described in claim 6, characterized in that, It also includes an upstream flow velocity sensor, which is installed 5 to 10 meters upstream of the sluice gate; the signal output terminal of the upstream flow velocity sensor is connected to the upstream flow velocity sensor signal input terminal of the data processor.

9. The novel sluice gate as described in claim 2, characterized in that... It also includes two sets of slide rail hinges and two sets of slide rail clamping devices; each of the two water-retaining slide rails has a slide rail hinge at its top. The fixed part of the slide rail hinge is installed on the outer wall of the main dam body, and the rotating and moving part of the slide rail hinge is installed at the top of the water-retaining slide rail. When the slide rail hinge is open, the slide rail rotates around the slide rail hinge and lifts away from the main dam body. When the slide rail hinge is closed, the slide rail rotates vertically around the slide rail hinge and falls close to the main dam body. The two sets of slide rail clamping devices have the same structure and are symmetrically arranged. One set of slide rail clamping devices includes: a clamping lever, a set of movable joints, a set of clamping electromagnets, and a spring locking tongue limiting device. The joint includes a first and a second fixing mechanism arranged face-to-face, and a movable joint disposed between the two fixing mechanisms. The first fixing mechanism is fixed to the clamping lever, and the second fixing mechanism is fixed to the slide rail. The axes of the two clamping levers are arranged horizontally. Taking the movable joint as a reference point, the part of the clamping lever between the two slide rails is the inner side, and the part outside the two slide rails is the outer side of the clamping lever. The inner side of the clamping lever is longer than the outer side. In the clamped state, a clamping electromagnet is installed at a corresponding position close to the inner end of the clamping lever, and the inner end of the clamping lever is made of a magnetic material. A spring-locking tongue limiting device is installed at the corresponding position of the outer end of the clamping lever, close to the main dam body. The spring-locking tongue limiting device includes a fixed locking body and a spring-locking tongue. The fixed locking body is fixed to the main dam body, and the spring-locking tongue is elastically mounted on the fixed locking body. The extension and retraction direction of the spring-locking tongue is parallel to the main dam body. The side of the spring-locking tongue facing the main dam body is a flat plane, and the other side of the spring-locking tongue facing away from the main dam body is an inclined plane that gradually slopes downwards towards the main dam body from the fixed locking body to the far end. In the clamping state, the outer end of the clamping lever is restricted between the plane of the spring-locking tongue and the main dam body. The inner end of the lever is attracted to the electromagnet; at this time, the clamping lever presses the slide rail against the main dam body; when the clamping electromagnet is de-energized, the inner end of the clamping lever is released, and the baffle plate and the slide rail are pushed upward by the water flow around the slide rail hinge. The bottom of the baffle plate and the slide rail move away from the main dam body; the clamping lever and the slide rail move away from the main dam body. Then the spring lock tongue prevents the outer end of the clamping lever from lifting, and the clamping lever rotates around the movable joint until it rotates to a sufficient angle. After that, the clamping lever slides off the spring lock tongue and enters the free state. When returning from the released state to the pressed state, the pressing lever gradually approaches the main dam body under the action of the slide rail. The outer end of the pressing lever presses against the inclined surface of the spring lock tongue, compressing the spring lock tongue until it retracts into the fixed lock body. At the same time, the inner end of the pressing lever approaches the pressing electromagnet. After the pressing electromagnet is energized, the inner end of the pressing lever is attracted to the pressing electromagnet.
