Description

Technical Field

[0001] The invention relates to the technical field of flow monitor devices, in particular to an anti-tilting Huangchi ditch pool body flood prevention flow monitor. Background Art

[0002] Huangchigou is a typical small water catchment area in mountainous areas. Affected by factors such as large terrain undulations and sudden rainfall, it is very easy to form mountain torrents in a short period of time, posing a serious threat to downstream villages and towns and infrastructure. As an important facility for water storage and regulation, the structural stability and flood control capabilities of the pond are directly related to flood prevention safety. However, most of the existing pond monitoring devices are single-function, mainly focusing on water level or rainfall monitoring, making it difficult to achieve dynamic perception and accurate recording of instantaneous flow, and especially lacking an effective early warning mechanism for the risk of pond overturning.

[0003] After searching, it was found that the prior art publication number is CN221527771U, which discloses a river water level monitor, including a floating shell, an air bag is provided at the bottom end of the inner wall of the floating shell, a guide cylinder is connected at the center of the bottom end of the outer wall of the floating shell, a lifting component is provided at the bottom end of the inner wall of the winding roller and directly above the guide cylinder, the bottom end of the lifting component passes through the guide cylinder and is fixed with a pressure water level detector, a vertical pole is installed at the top end of the outer wall of the floating shell, and an ultrasonic water level detector is installed at the upper end of the vertical pole. This scheme can measure the water level by detecting the water pressure at the bottom of the river and then performing corresponding calculations through the set pressure water level detector, and can monitor the water level at the monitoring point by ultrasonic detection through the set ultrasonic water level detector, so that personnel can monitor the water level of the monitoring point at the required location through this device.

[0004] Therefore, based on the above search and combined with existing technologies, many float devices fail to effectively cope with the impact force caused by violent fluctuations in the water surface, resulting in frequent up and down movement of the float under extreme water flow conditions, thereby affecting the stability and service life of the equipment. The traditional structure lacks an effective buffer mechanism and cannot adjust the contact state between the float and the steel cable in time, which may cause damage or failure of the internal device, affecting the accuracy and reliability of measurement and monitoring. For this reason, this application proposes an anti-tilt Huangchigou pool flood control flow monitor. Summary of the Invention

[0005] The purpose of the present invention is to provide a flood prevention flow monitor for a Huangchi ditch pool body that is anti-tilting, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a Huangchigou pool body flood prevention flow monitor for preventing overturning, comprising a support rod, an extension rod fixedly installed on the upper end of the support rod, a float arranged below the extension rod, a steel cable passed through the inner end of the float, and the end of the steel cable away from the float is fixedly connected to the extension rod, the bottom end of the float is fixedly connected to a stabilizing cylinder, a plurality of air bags are fixedly sleeved on the outer surface of the stabilizing cylinder, and the air bags keep the float on the water surface at all times through the buoyancy effect, and are used for real-time measurement of the vertical movement distance of the float to reflect the water level change and the deformation trend of the pool body, the end of the steel cable away from the stabilizing cylinder is fixedly connected to a fixing cone, and the fixing cone penetrates the bottom of the pool to keep the steel cable in a vertical state and prevent the steel cable from drifting under the influence of water flow, the inner end of the stabilizing cylinder is penetrated by a monitoring cylinder, and the outer surface of the stabilizing cylinder is sleeved with a pulp plate.

[0007] As a further solution of the present invention, a center rod is rotatably installed on the inner end of the monitoring tube, a rotating sleeve is fixed on the outer surface of the center rod, and a plurality of fan blades are rotatably installed on the outer surface of the rotating sleeve. The fan blades are arranged in a ring shape and automatically unfold and rotate under the action of water flow.

[0008] As a further solution of the present invention, the inner end of the rotating sleeve is provided with a support ring, and a plurality of downward pressure rods are rotatably installed on the outer surface of the rotating sleeve. The downward pressure rods are arranged in a ring shape, and a plurality of through holes are opened on the outer surface of the rotating sleeve. Force blocks are passed through the through holes, and the force blocks correspond to the downward pressure rods. One end of the downward pressure rod away from the force block contacts the outer surface of the fan blade, and the other end contacts the outer surface of the force block.

[0009] As a further solution of the present invention, a passive ring is provided inside the rotating sleeve. The passive ring is connected to the rotating sleeve via a return spring, and the force-bearing block is connected to the rotating sleeve via a passive spring. When the force-bearing block is compressed, the passive spring pushes the passive ring away from the support ring. The coordinated design of the rotating sleeve, passive ring, return spring, and passive spring effectively achieves automatic adjustment of the force-bearing block after compression. Under the action of force, the passive ring moves away from the support ring, thereby ensuring the flexibility and stability of the system.

[0012] As a further solution of the present invention, a rotating rod is rotatably installed on the inner end of the detection surface shell, and a swing plate is fixedly sleeved on the outer surface of the rotating rod, and an air guide cylinder is fixedly installed on the inner end of the detection surface shell. Through the design of the rotating rod and the swing plate, precise swing adjustment can be achieved during the detection process, ensuring that the detection surface shell can adapt to different working environments and conditions.

[0013] As a further solution of the present invention, a movable plug is passed through the inner end of the gas guide cylinder, and the end of the movable plug close to the rotating rod is fixedly connected to an abutment sleeve, and the end of the rotating rod close to the abutment sleeve is fixedly connected to an abutment column, and an arc-shaped groove is provided on the side of the abutment sleeve close to the abutment column, and the abutment column is passed through the groove.

[0014] As a further solution of the present invention, a rotating plate is rotatably installed on the inner bottom end of the float, and two supporting wheels are rotatably installed on the inner end of the rotating plate. The outer surface of the steel cable contacts the outer surfaces of the two supporting wheels respectively. Through the design of the rotating plate and the supporting wheels, it can be ensured that the steel cable always maintains a stable contact state when the float moves, avoiding deviation of the steel cable due to water fluctuations or shaking of the float, thereby ensuring the accuracy and stability of the measurement.

[0015] As a further solution of the present invention, a support plate is fixedly installed on the inner bottom end of the float, and a depth meter is fixedly installed on the end of the support plate away from the rotating plate.

[0018] 2. When the present invention is in use, when the water surface fluctuates violently, the buoyancy generated by the buffer bag can drive the movable ring to drive the rotating plate to deflect, so that the support wheel is automatically adjusted to a vertical state and the steel cable is tightened, thereby limiting the violent up and down movement of the float, effectively buffering the impact force, preventing damage to the internal device, and improving the stability and service life of the entire device;

[0019] 3. When the present invention is in use, the auxiliary sleeve is pushed to move and drive the fan blades to rotate through the water flow, and the center rod rotates accordingly.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figure 1-Figure 3 , a Huangchi ditch pool body flood control flow monitor for preventing overturning, comprising a support rod 1, an extension rod 11 is fixedly installed on the upper end of the support rod 1 by bolts, a float 3 is provided below the extension rod 11, a steel cable 2 is passed through the inner end of the float 3, and the end of the steel cable 2 away from the float 3 is fixedly connected to the extension rod 11, specifically, embedded parts are embedded in the embankment of the pool body, and the support rod 1 is fixed to the embedded parts by locking bolts to achieve stable installation and prevent it from tipping over when standing for a long time, and a signal transmitter is provided at the inner end of the support rod 1 for transmitting flood flow status information in real time;

[0039] A stabilizing cylinder 5 is fixedly welded to the bottom end of the float 3, and a plurality of air bags 4 are fixedly sleeved on the outer surface of the stabilizing cylinder 5. The air bags 4 keep the float 3 on the water surface at all times through the buoyancy. The end of the steel cable 2 away from the stabilizing cylinder 5 is fixedly connected to the fixing cone 6. The fixing cone 6 passes through the bottom of the pool to keep the steel cable 2 in a vertical state and prevent the steel cable 2 from drifting due to the influence of the water flow. It is used to measure the vertical movement distance of the float 3 in real time to reflect the water level changes and the deformation trend of the pool body. A monitoring cylinder 101 is passed through the inner end of the stabilizing cylinder 5, and a water flow monitoring device is provided inside the monitoring cylinder 101 for real-time monitoring of the water flow rate. A paddle plate 102 is sleeved on the outer surface of the stabilizing cylinder 5. When the water flows through the stabilizing cylinder 5, the paddle plate 102 automatically maintains the downstream direction to ensure that the water flows smoothly through the monitoring cylinder 101, thereby improving the monitoring accuracy.

[0040] See also Figure 3-Figure 6 The inner end of the monitoring tube 101 is rotatably mounted with a center rod 105, and the center rod 105 is rotatably mounted on the inner end of the monitoring tube 101. The outer surface of the center rod 105 is fixedly sleeved with a rotating sleeve 103, and the outer surface of the rotating sleeve 103 is rotatably mounted with a plurality of fan blades 106 through a rotating shaft. The fan blades 106 are arranged in a ring and automatically unfold and rotate under the action of water flow. The outer surface of the center rod 105 is sleeved with an auxiliary sleeve 104, and the auxiliary sleeve 104 is funnel-shaped, with the opening in the direction of water flow in, and the outer surface of the auxiliary sleeve 104 contacts the outer surface of the fan blades 106. The auxiliary sleeve 104 moves toward the direction of the rotating sleeve 103 under the action of the water flow, and during the movement, it pushes the fan blades 106 to rotate and opens the fan blades 106. The auxiliary sleeve 104 and the rotating sleeve 103 are connected by a pressure spring 107;

[0041] The inner end of the rotating sleeve 103 is provided with a support ring 110, and the outer surface of the rotating sleeve 103 is installed with multiple pressure rods 108 through the rotation of the rotating shaft. The pressure rods 108 are arranged in a ring shape, and the outer surface of the rotating sleeve 103 is provided with multiple through-holes, and force blocks 109 are penetrated in the through-holes, and the force blocks 109 correspond to the pressure rods 108. Specifically, one end of the pressure rod 108 away from the force block 109 contacts the outer surface of the fan blade 106, and the other end contacts the outer surface of the force block 109. After the fan blade 106 rotates a certain angle, it drives the pressure rod 108 to rotate. When the pressure rod 108 rotates, it squeezes the force block 109 to make it move toward the inside of the rotating sleeve 103.

[0042] Example 2: Please refer to Figure 6-Figure 8, a flood control flow monitor for the Huangchi ditch pool body that prevents tipping, based on the basis of Example 1, the support ring 110 corresponds to the force block 109, and the inner sleeve of the rotating sleeve 103 is provided with a passive ring 111, and the passive ring 111 and the rotating sleeve 103 are connected by a reset spring 112, and the force block 109 and the rotating sleeve 103 are connected by a passive elastic piece 113. Specifically, a rounded guide groove is provided at the inner end of the support ring 110 to guide the passive elastic piece 113 to achieve steering. After the force block 109 is compressed, the passive ring 111 is pushed away from the support ring 110 through the passive elastic piece 113;

[0043] The inner end of the monitoring tube 101 is fixedly mounted with a central tube 301 by means of bolts. The central rod 105 is rotatably connected to the central tube 301. A passive sleeve 303 is passed through the inner end of the central tube 301. The passive sleeve 303 is rotatably connected to the passive ring 111. A rotation sensor 114 is fixedly mounted on the inner end of the central tube 301 by means of a clamp. The rotating shaft of the rotation sensor 114 is fixedly connected to the central rod 105. The rotation sensor 114 is an existing mature technology. The specific working principle will not be described in detail here. The rotation of the central rod 105 drives the input shaft of the rotation sensor 114 to rotate. The water flow velocity is calculated by combining the rotation speed and the internal volume of the monitoring tube 101 (the internal volume of the monitoring tube 101 is a fixed value), thereby determining the real-time water flow rate: ;

[0044] Where Q is the volume flow rate (m³ / s), A is the effective water flow cross-sectional area inside the monitoring tube 101 (m2), and v is the average velocity of the water flow (m / s). The water flow velocity is then converted into a rotational speed according to the linear relationship of the conversion: , where n is the rotation speed of the rotary sensor 114, k is the proportional coefficient related to the structure (m / revolution), and the volume of water flowing in a certain time t is, ;

[0045] It is worth noting that the above calculation steps are all calculated after the rotation sensor 114 transmits the data back to the monitoring center;

[0046] A conductive tube 304 is fixedly welded to one end of the passive sleeve 303 away from the center rod 105. A rectangular groove is provided on the outer surface of the conductive tube 304. A rectangular block is fixedly installed on the inner end of the center tube 301. The rectangular block is embedded in the rectangular groove to prevent the conductive tube 304 from rotating during reciprocating motion.

[0047] like Figure 8 、 Figure 9As shown, a rectangular hole is provided on the outer surface of the central tube 301, and a detection surface shell 302 is passed through the rectangular hole. The detection surface shell 302 is rotatably connected to the central tube 301, and a passive ejector rod 305 is rotatably installed on the end of the conductive tube 304 away from the passive sleeve 303 through a rotating shaft, and the passive ejector rod 305 is located below the detection surface shell 302, and a triangular plate 306 is fixedly welded to the inner end of the central tube 301, and the triangular plate 306 corresponds to the passive ejector rod 305. Specifically, the end of the passive ejector rod 305 away from the conductive tube 304 contacts the inclined surface of the triangular plate 306. When the conductive tube 304 moves in a direction away from the central rod 105, the passive ejector rod 305 is squeezed by the inclined surface of the triangular plate 306, begins to rotate upward, and begins to squeeze the detection surface shell 302.

[0048] More specifically, a triangular guide plate is provided on the outer surface of the detection surface shell 302 to reduce water flow resistance and ensure smooth flow.

[0049] A rotating rod 401 is rotatably mounted on the inner end of the detection surface shell 302, and a swing plate 402 is fixedly sleeved on the outer surface of the rotating rod 401. When the detection surface shell 302 rotates (the detection surface shell 302 is now intersecting with the central tube 301), the swing plate 402 is exposed on the outside of the central tube 301. As the water flows through the guide plate on the outer surface of the detection surface shell 302, a Karman vortex street effect is formed at the swing plate 402, driving the swing plate 402 to swing back and forth.

[0050] An air guide cylinder 406 is fixedly installed at the inner end of the detection surface shell 302, and a movable plug 405 is passed through the inner end of the air guide cylinder 406, and the movable plug 405 and the air guide cylinder 406 are connected by a reset spring piece. The movable plug 405 is fixedly welded with an abutment sleeve 404 at one end close to the rotating rod 401, and the rotating rod 401 is fixedly welded with an abutment column 403 at one end close to the abutment sleeve 404. An arc-shaped groove is provided on the side of the abutment sleeve 404 close to the abutment column 403, and the abutment column 403 is passed through the groove. When the rotating rod 401 rotates back and forth, it rotates back and forth through the abutment column 403. At this time, the abutment column 403 rotates in the arc-shaped groove of the abutment sleeve 404 and squeezes the abutment sleeve 404, so that the movable plug 405 moves away from the rotating rod 401. Subsequently, during the resetting process of the abutment column 403, the movable plug 405 returns to its initial state under the elastic force of the reset spring piece, and reciprocates in this way.

[0051] Example 3: Please refer to Figure 10-12, a flood control flow monitor for the Huangchi ditch body that prevents tipping over, based on the basis of Examples 1 and 2, a rotating plate 204 is rotatably installed on the inner bottom end of the float 3, and two supporting wheels 207 are rotatably installed on the inner end of the rotating plate 204 through a rotating shaft. The outer surfaces of the steel cable 2 are respectively in contact with the outer surfaces of the two supporting wheels 207. Specifically, the two supporting wheels 207 squeeze the steel cable 2 into an "S" shape, and the outer surfaces of the two supporting wheels 207 are engraved with diamond-shaped anti-skid grooves to provide better biting force on the steel cable 2 and further prevent slipping;

[0052] A support plate 205 is fixed to the inner bottom end of the float 3 by bolts, and a depth meter 206 is fixed to the end of the support plate 205 away from the rotating plate 204 by bolts. The support wheel 207 located below is fixedly connected to the input shaft of the depth meter 206. Specifically, the rotation center of the rotating plate 204 coincides with the rotation axis of the support wheel 207. When the float 3 moves up or down, the support wheel 207 rotates under the action of the friction between the steel cable 2. The depth meter 206 will calculate the height of the current water level line according to the number of rotations of the support wheel 207 when it moves up or down, and use this to determine whether it is the flood season. The specific working principle of the depth meter 206 is an existing mature technology and will not be elaborated here.

[0053] like Figures 8-11 As shown, a sensing tube 203 is fixedly mounted on the inner bottom end of the float 3, a probe 310 is rotatably mounted on the inner end of the sensing tube 203, the end of the probe 310 is a magnetic head, an encoder is fixedly mounted on the inner end of the sensing tube 203, and through the magnetic swing of the end of the sensing probe 310, a control terminal (not shown in the figure) is fixedly mounted on the inner end of the sensing tube 203 for integrating the swing signal state of the encoder detection probe 310 into an instantaneous flow diagram and transmitting it back to the monitoring center;

[0054] An output air push rod 309 is fixed to the inner end of the sensing tube 203 by bolts. The telescopic end of the output air push rod 309 contacts the bump on the outer surface of the probe 310. The bump of the probe 310 and the sensing tube 203 are connected by an auxiliary spring 311. After the telescopic end of the output air push rod 309 pushes the probe 310 to rotate through the bump, it then returns to its initial state under the elastic force of the auxiliary spring 311.

[0055] The central tube 301 and the sensing tube 203 are connected via an outer protective tube 307 , and the output gas push rod 309 and the gas guide tube 406 are connected via an air guide tube 308 , which is disposed inside the outer protective tube 307 .

[0056] like Figure 12As shown, when the water surface fluctuates violently, in order to prevent the float 3 from being affected and causing damage to the internal device, a buffer ring 201 is provided on the inner end of the float 3, and a plurality of buffer capsules 202 are fixedly connected to the outer surface of the buffer ring 201 through a clamp. A movable ring 208 is rotatably installed on the inner end of the buffer ring 201, and the movable ring 208 is rotatably connected to the upper end of the rotating plate 204. When the water surface fluctuates and directly submerges the buffer capsule 202, the buffer capsule 202 drives the rotating plate 204 to move away from the float 3 through the movable ring 208 under the action of buoyancy. At this time, the two support wheels 207 gradually tend to be vertical, and thereby tighten the steel cable 2 (under normal conditions, the two support wheels 207 are not in a horizontal state, ensuring that they are always in contact with the outer surface of the steel cable 2). Under the action of the extrusion force, the float 3 is prevented from moving up and down frequently.

[0057] The working principle of the present invention is:

[0058] During operation, when water flows through the interior of the monitoring tube 101, the float 3 moves upward or downward, and the support wheel 207 rotates under the action of the friction between the support wheel 207 and the steel cable 2. The depth meter 206 calculates the current water level according to the number of rotations of the support wheel 207 when it moves upward or downward, and uses this to determine whether it is the flood season;

[0059] The auxiliary sleeve 104 moves toward the rotating sleeve 103 under the action of the water flow, pushing the fan blades 106 to rotate and open during the movement. Then, when the water flows through, the fan blades 106 are driven to rotate, and the central rod 105 begins to rotate. At this time, the monitoring center calculates the current water flow rate based on the rotation speed of the fan blades 106 using the rotation sensor 114;

[0060] When the speed of the water flow becomes faster, the auxiliary sleeve 104 moves toward the rotating sleeve 103 under the action of the extrusion force, so that the fan blades 106 are further opened. Due to the faster speed of the water flow, the fan blades 106 rotate faster. Since the angle of the fan blades 106 is larger, the lower pressure rod 108 is driven to rotate, and the lower pressure rod 108 begins to squeeze the force block 109 to move in the direction of the support ring 110. Then the force block 109 pushes the passive ring 111 to move through the passive spring piece 113. During the movement of the passive ring 111, the passive sleeve 303 and the conductive tube 304 are driven to move, and then the passive push rod 305 also moves accordingly. The end of the passive push rod 305 away from the conductive tube 304 contacts the inclined surface of the triangular plate 306. When the conductive tube 304 moves in the direction away from the center rod 105, the passive push rod 305 is squeezed by the inclined surface of the triangular plate 306 and begins to rotate upward, and begins to squeeze the detection surface shell 302 to rotate;

[0061] After the detection surface shell 302 rotates and is exposed on the outside of the central tube 301, the water flows through the detection surface shell 302 to form a Karman vortex street effect, which begins to drive the swing plate 402 to swing, and the abutment column 403 rotates in the arc-shaped groove of the abutment sleeve 404 and squeezes the abutment sleeve 404, causing the movable plug 405 to move in the direction away from the rotating rod 401. Subsequently, during the resetting process of the abutment column 403, the movable plug 405 returns to its initial state under the elastic force of the resetting spring piece, and reciprocates in this way. The movable plug 405 begins to regularly squeeze the air inside the air guide cylinder 406. The faster the water flow rate, the faster the activity frequency of the movable plug 405, which makes the telescopic end of the output air push rod 309 drive the probe 310 to swing faster. The control terminal integrates the swing amplitude signal state of the encoder detection probe 310 into an instantaneous flow graph, and transmits it back to the monitoring center, and uses it for analysis to determine whether it is the flood season.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
