Description

Technical Field

[0001] This utility model relates to the field of gate opening monitoring technology, specifically to an integrated gate opening meter. Background Technology

[0002] In early water conservancy projects, the monitoring of gate opening mainly relied on manual observation or mechanical measurement, such as rulers and dials, which had the following problems: low accuracy: manual readings are easily affected by the environment and have large errors; poor real-time performance: remote monitoring is not possible and it is difficult to meet the needs of automated control; difficult maintenance: mechanical parts are easily worn and require frequent calibration.

[0003] With the development of automation technology, split-type gate opening instruments have emerged, which are usually composed of sensors, transmitters, and display instruments. However, they still have shortcomings: complex installation: separate sensor and signal transmission lines are required, making construction difficult; low reliability: many connecting parts, high failure rate, and high maintenance cost. Utility Model Content

[0004] The purpose of this invention is to provide an integrated gate opening meter to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An integrated gate opening device includes a base, on the top of which a wire rope guide wheel assembly is fixedly mounted. A transmission assembly is rotatably mounted on the right side of the wire rope guide wheel assembly. An encoder is located on the right side of the transmission assembly. A limit sensor assembly and a limit trigger assembly are located on the top of the base. The transmission assembly and the limit trigger assembly rotate. The front side of the limit trigger assembly is in contact with the rear trigger point of the limit sensor assembly. The wire rope guide wheel assembly includes a wire rope body, one end of which is connected to the gate.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the base includes a connecting plate and a bottom plate, with the bottom plate fixedly installed on top of the connecting plate.

[0009] Furthermore, the wire rope guide wheel assembly also includes a spring chamber, a wire rope winding wheel, a rope guide wheel, and mounting plates. There are two mounting plates, which are fixedly installed on the top of the base plate. The spring chamber is fixedly installed on the rear side of the left mounting plate. The wire rope winding wheel is rotatably installed inside the two mounting plates. The left side of the central axis of the wire rope winding wheel extends into the spring chamber and is connected to the inner end of the spring. There are two rope guide wheels, both of which are rotatably installed inside the two mounting plates. The wire rope body is wound along the outer side of the outer circumference of the wire rope winding wheel, and both ends pass over the two rope guide wheels and extend forward.

[0010] Furthermore, the wire rope guide wheel assembly also includes a lead wire fixing plate, a wire rope output guide wheel, and a connecting bracket. The lead wire fixing plate is fixed to the front side of the two mounting plates. A lead wire sleeve is provided on the front side of the lead wire fixing plate. The wire rope output guide wheel is fixedly installed on the left side of the connecting bracket. A pin is provided inside the wire rope output guide wheel. The front side of the wire rope body enters the interior of the wire rope output guide wheel and is located behind the pin.

[0011] Furthermore, the transmission assembly includes a large gear, a small gear, a fixed block, a worm, and a worm wheel. The interior of the large gear is fixedly connected to the right side of the central shaft of the wire rope winding wheel. The encoder is fixed by the fixed block. The left side of the encoder is fixedly connected to the interior of the small gear. The large gear and the small gear mesh with each other. The worm is fixedly connected to the outside of the central shaft of the wire rope winding wheel. The worm and the worm wheel mesh with each other.

[0012] Furthermore, the limit sensor assembly includes a sensor bracket and limit sensors. The sensor bracket is fixedly installed on the top of the base plate, and there are two limit sensors, which are evenly distributed inside the sensor bracket.

[0013] Furthermore, the limit triggering component includes a rotating shaft, an upper limit block, and a lower limit block. The rotating shaft is rotatably mounted on the top of the base plate. The inside of the worm gear is fixedly connected to the outside of the rotating shaft. The upper limit block and the lower limit block are both fixedly mounted on the outside of the rotating shaft. The front sides of the upper limit block and the lower limit block are respectively attached to the rear trigger points of the two limit sensors.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] When the gate opening changes, the wire rope body pulls the wire rope winding wheel to rotate. Under the action of the central shaft of the wire rope winding wheel, the large gear rotates, and the meshing small gear rotates synchronously, thereby driving the encoder to work. The encoder can convert the mechanical rotation angle into an electrical signal in real time. By calculating the correspondence between the rotation angle and the wire rope stroke, the current opening value of the gate can be output in real time, thereby monitoring the gate status in real time and avoiding safety accidents caused by jamming or over-limit operation.

[0016] By monitoring the opening of the encoder, the actual opening of the gate is fed back in real time. In conjunction with the limit sensor, the gate is triggered to be fully open or fully closed, thereby accurately controlling the opening of the gate during irrigation or water supply and reducing water waste.

[0017] With its integrated design, on-site installation only requires connecting the front of the wire rope body to the gate and fixing the base on-site. Then, the power supply and controller connection lines are connected, which greatly reduces the workload of on-site assembly and debugging and facilitates rapid installation.

[0018] Its internal transmission structure mainly relies on the wire rope body, wire rope winding wheel, gears and worm gears, without complex electronic components. Furthermore, the encoder and limit sensor are well-known components, which improves the reliability during use. In addition, the two limit sensors can be used together to avoid the safety risks caused by the failure of a single sensor. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 As shown, this utility model provides an integrated gate opening device, including a base 1, a wire rope guide wheel assembly 2 fixedly installed on the top of the base 1, a transmission assembly 3 rotatably installed on the right side of the wire rope guide wheel assembly 2, an encoder 4 provided on the right side of the transmission assembly 3, a limit sensor assembly 5 provided on the top of the base 1, and a limit trigger assembly 6 provided on the top of the base 1. The transmission assembly 3 and the limit trigger assembly 6 rotate, and the front side of the limit trigger assembly 6 is in contact with the rear trigger point of the limit sensor assembly 5. The wire rope guide wheel assembly 2 includes a wire rope body 201, one end of which is connected to the gate.

[0027] The base 1 includes a connecting plate 101 and a base plate 102, with the base plate 102 fixedly installed on the top of the connecting plate 101.

[0028] With this configuration, the connecting plate 101 is installed using a U-shaped profile, which has inwardly extending support flanges. This allows the bottom of the base plate 102 to fit snugly against the top of the support flanges during installation. Furthermore, the base plate 102 can be positioned and installed using the pre-drilled mounting holes on the support flanges (processed during the U-shaped profile forming process). This eliminates the need for separate marking and drilling on the connecting plate 101 and base plate 102 on-site, thus increasing installation speed and distributing the stress on the base plate 102, reducing the load on fasteners, and thereby improving the stability of the entire opening meter during use.

[0029] The wire rope guide wheel assembly 2 also includes a spring chamber 202, a wire rope winding wheel 203, a rope guide wheel 204, and a mounting plate 205. There are two mounting plates 205, which are fixedly installed on the top of the base plate 102. The spring chamber 202 is fixedly installed on the rear side of the left mounting plate 205. The wire rope winding wheel 203 is rotatably installed inside the two mounting plates 205. The left side of the central axis of the wire rope winding wheel 203 extends into the spring chamber 202 and is connected to the inner end of the spring. There are two rope guide wheels 204, which are rotatably installed inside the two mounting plates 205. The wire rope body 201 is wound along the outer side of the outer circumference of the wire rope winding wheel 203, and both ends pass around the two rope guide wheels 204 and extend forward.

[0030] With this configuration, when the gate is opened, the wire rope body 201 is pulled, and the wire rope winding wheel 203 rotates as the wire rope body 201 is pulled. This causes the spring in the spring chamber 202 to twist and store elastic potential energy, resulting in a restoring torque on the wire rope winding wheel 203 during its rotation. This torque is transmitted through the central axis of the wire rope winding wheel 203, applying a rewinding force to the wire rope body 201 wound around the outside of the wire rope winding wheel 203. At the same time, the two rope guide wheels 204 limit the direction of the wire rope body 201, forming a tensioning path. This ensures that the wire rope body 201 remains taut under the combined action of the rewinding force and the guiding action of the rope guide wheels 204.

[0031] The wire rope guide wheel assembly 2 also includes a lead wire fixing plate 206, a wire rope output guide wheel 207, and a connecting bracket 209. The lead wire fixing plate 206 is fixed to the front side of the two mounting plates 205. A lead wire sleeve 208 is provided on the front side of the lead wire fixing plate 206. The wire rope output guide wheel 207 is fixedly installed on the left side of the connecting bracket 209. A pin 210 is provided inside the wire rope output guide wheel 207. The front side of the wire rope body 201 enters the interior of the wire rope output guide wheel 207 and is located behind the pin 210.

[0032] This configuration, with the wire rope body 201 pulled forward along the path of the guide plate 206, the wire rope output guide wheel 207, the guide sleeve 208 (with an inner hole that fits the diameter of the wire rope body 201), and the pin 210, constrains the wire rope body 201 onto a fixed axial path. This avoids errors in opening monitoring caused by slippage or entanglement of the wire rope body 201 due to external factors such as gate vibration. Furthermore, under the action of the wire rope output guide wheel 207, rolling friction replaces sliding friction, significantly reducing the transmission resistance of the wire rope body 201. Combined with the preload of the coil spring, stable tension is maintained, preventing slack or excessive bending, and ensuring the stability of the wire rope body 201 during use.

[0033] The transmission assembly 3 includes a large gear 301, a small gear 302, a fixed block 303, a worm 304, and a worm wheel 305. The interior of the large gear 301 is fixedly connected to the right side of the central shaft of the wire rope winding wheel 203. The encoder 4 is fixed by the fixed block 303. The left side of the encoder 4 is fixedly connected to the interior of the small gear 302. The large gear 301 and the small gear 302 mesh with each other. The worm 304 is fixedly connected to the outside of the central shaft of the wire rope winding wheel 203. The worm 304 and the worm wheel 305 mesh with each other.

[0034] With this configuration, as the wire rope winding wheel 203 rotates, the rotation of its central shaft causes the large gear 301 to rotate, which in turn causes the small gear 302 to rotate further. Under the action of the coupling, the encoder 4 on the fixed block 303 is driven to work, thereby monitoring the opening degree of the gate by rotation. Furthermore, the central shaft drives the worm gear 304 to rotate, causing the worm wheel 305 to rotate synchronously.

[0035] The limit sensor assembly 5 includes a sensor bracket 501 and a limit sensor 502. The sensor bracket 501 is fixedly installed on the top of the base plate 102, and there are two limit sensors 502, which are evenly distributed inside the sensor bracket 501.

[0036] This configuration improves the stability of limit information transmission through two limit sensors 502, preventing problems caused by a single sensor that could prevent the transmission of limit information and lead to safety hazards.

[0037] The limit trigger assembly 6 includes a rotating shaft 601, an upper limit block 602, and a lower limit block 603. The rotating shaft 601 is rotatably mounted on the top of the base plate 102. The inside of the worm gear 305 is fixedly connected to the outside of the rotating shaft 601. The upper limit block 602 and the lower limit block 603 are both fixedly mounted on the outside of the rotating shaft 601. The front sides of the upper limit block 602 and the lower limit block 603 are respectively attached to the rear trigger points of the two limit sensors 502.

[0038] With this configuration, the worm gear 305 rotates synchronously during the opening and closing of the gate, which in turn drives the rotating shaft 601 to rotate. This causes the upper limit block 602 and the lower limit block 603 to rotate synchronously and come into contact with the rear trigger points of the two limit sensors 502, thereby achieving the function of transmitting limit information.

[0039] Working principle: A coil spring is installed inside the spring chamber 202, which keeps the wire rope body 201 wound on the wire rope winding wheel 203 in a naturally taut state. The wire rope body 201 on the wire rope output guide wheel 207 is connected to the gate. The gate rises or falls, causing the wire rope winding wheel 203 to rotate. The wire rope winding wheel 203 transmits power through the central shaft to the large gear 301, which drives the small gear 302 to rotate. The central shaft of the small gear 302 is connected to the encoder 4, which records data. At the same time, the rotation of the large gear 301 also drives the worm gear 304 on the same central shaft to drive the worm wheel 305 to rotate. The rotation of the rotating shaft 601 connected to the worm wheel 305 causes the upper limit block 602 and the lower limit block 603 on the rotating shaft 601 to rotate by an angle, hitting the adjusted limit sensor 502, so that it plays a limiting role when the gate rises or falls to its limit.
