[0002] A sluice is a hydraulic structure used to control water flow, with the dual functions of retaining water and discharging water. It is mainly composed of a gate panel, a hoist, a driving screw, a control cabinet and other structures.

[0003] When the existing small sluices are in use, generally, the hoist of the gate panel is controlled by a wired control cabinet fixedly installed beside the sluice. And because many of the existing small sluices do not have intelligent control functions, the control operation of the existing small sluices completely depends on manual labor, which is very inconvenient, and the accuracy of manual control of the sluice is also relatively low.

[0004] Therefore, it is very necessary to invent a portable small sluice intelligent control detection device to solve the above problems. Summary of the Invention

The centers of the spherical clamping strip, the center of the arc-shaped groove, and the center of the spherical protrusion coincide, and the outer arc surface of the spherical protrusion is kept in contact with the inner arc surface of the spherical clamping strip.

[0010] Further, the centering structure includes a limiting block, an adjusting rod, a gear, a limiting rod, an adjusting plate, and a locking structure. The number of the adjusting plates is two, and the adjusting plates are semi-annular structures. An annular groove is provided on the top surface after the two reflectors are spliced together, and the two adjusting plates are rotatably installed in the annular groove.

Since the reflector is in a horizontal state, it can ensure that the vertical distances at each position on the top of the reflector irradiated by the laser sensor are the same, thus avoiding the detection error of the laser sensor caused by the inclination of the reflector, and then improving the accuracy of controlling the gate panel.

[0020] 3. By providing a centering structure, before using the laser sensor in cooperation with the reflector to detect the moving distance of the driving screw in the vertical direction, the reflector and the driving screw can be coaxially adjusted through the centering structure, thus avoiding deviation in the position where the laser sensor irradiates on the adjusting plate, and then ensuring the accuracy of the laser sensor in detecting the moving distance of the driving screw in the vertical direction in subsequent cooperation with the adjusting plate.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0033] The present invention provides asFigures 1 to 10 A portable small sluice intelligent control detection device shown in the figure includes a sluice component and a control box 1. A detection component is arranged in the control box 1. The detection component includes a laser sensor 2. A sensing connection mechanism is connected to the side of the laser sensor 2 for installing the laser sensor 2 on the sluice component. A reflection mechanism used in cooperation with the laser sensor 2 is arranged at the bottom of the laser sensor 2. The reflection mechanism includes two semi-annular fixed bases 3. An arc-shaped groove is formed at the top of the fixed base 3. The arc-shaped grooves at the tops of the two fixed bases 3 can be perfectly spliced together, and the centers of the two arc-shaped grooves are at the same position. A magnetic part 4 is installed at the bottom of the fixed base 3. The magnetic part 4 can be a magnet. First insertion blocks 5 are fixedly connected to both ends of one of the fixed bases 3. First insertion holes 6 matching the first insertion blocks 5 are formed at both ends of the other fixed base 3. Two semi-annular reflection plates 7 are correspondingly arranged at the tops of the two fixed bases 3. Second insertion blocks 8 are fixedly connected to both ends of one of the reflection plates 7. Second insertion holes 9 matching the second insertion blocks 8 are formed at both ends of the other reflection plate 7. A sensing leveling structure for leveling the reflection plate 7 is arranged at the bottom of the reflection plate 7. A centering structure for keeping the reflection plate 7 coaxial with the sluice component is arranged on the inner side surface of the reflection plate 7. The sluice component is an existing sluice structure, including a gate plate 27, a driving screw 28, a portal fixing member 29, and a hoist 30 for driving the driving screw 28 to move in the vertical direction. The gate plate 27 is slidably installed vertically inside the portal fixing member 29. The driving screw 28 vertically penetrates and is inserted into the top of the portal fixing member 29, and the bottom end of the driving screw 28 is rotatably connected to the top of the gate plate 27. The hoist 30 is sleeved on the driving screw 28, and the bottom of the hoist 30 is fixedly connected to the top of the portal fixing member 29. A storage battery and an MCU are built in the control box 1. The storage battery is used to supply power to the hoist 30. The laser sensor 2 communicates with the MCU in the control box 1 by means of Bluetooth;

[0034] The sensing connection mechanism includes a sensing connection block 10, a sensing clamping block 11, a sensing extrusion block 12, and a sensing adjustment screw 13. The sensing connection block 10 is fixedly connected to the side of the laser sensor 2. The sensing clamping block 11 is detachably and slidably clamped with the sensing connection block 10. The sides of the sensing clamping block 11 and the sensing connection block 10 facing each other are both arc-shaped designs. A sliding groove is formed on the side of the sensing clamping block 11 close to the sensing connection block 10. The sensing extrusion block 12 is slidably installed horizontally in the sliding groove, and the side of the sensing extrusion block 12 facing the sensing connection block 10 is also an arc-shaped design. The sensing adjustment screw 13 vertically threadedly penetrates and is inserted into the side of the sensing clamping block 11 away from the sensing connection block 10, and the end of the adjustment rod 20 close to the sensing connection block 10 is rotatably connected to the sensing extrusion block 12;

[0035] When controlling an existing small sluice, the control box 1 is pulled to the position of the existing sluice. Then, the power supply in the control box 1 is connected to the hoist 30 of the existing small sluice. After the connection is completed, the detection component is taken out from the control box 1. First, the arc surface of the side sensing connection block 10 of the laser sensor 2 is pressed tightly against the driving screw 28. Subsequently, the sensing clamping block 11 is clamped with the sensing connection block 10 from top to bottom. Then, the sensing adjustment screw 13 is turned, so that the sensing pressing block 12 gradually approaches the surface of the driving screw 28 under the pushing action of the sensing adjustment screw 13. When the sensing pressing block 12 is pressed tightly against the surface of the driving screw 28, the laser sensor 2 can be fixed on the driving screw 28 under the clamping action of the sensing pressing block 12 and the sensing connection block 10 on the driving screw 28;

[0036] After the laser sensor 2 is fixed on the driving screw 28, the two reflecting plates 7 are sleeved on the driving screw 28 through the second plug blocks 8 and the second jacks 9. Then, the fixed base 3 is sleeved on the driving screw 28 through the first plug blocks 5 and the first jacks 6 and is located at the bottom of the reflecting plate 7. The bottom of the fixed base 3 can be adsorbed on the top of the hoist 30 through the magnetic part 4, so as to ensure the stability of the fixed base 3. After the fixed base 3 is assembled, the reflecting plate 7 can be connected to the fixed base 3 through the sensing leveling structure. The reflecting plate 7 can be adjusted first through the centering structure, so that the adjusting plate 23 can be coaxial with the driving screw 28. Furthermore, during the subsequent detection process, as the driving screw 28 drives the laser sensor 2 to rotate and rise, the laser emitted by the laser sensor 2 can be irradiated on the same annular area of the reflecting plate 7, thereby reducing the error during the detection of the laser sensor 2;

[0037] After the centering adjustment operation of the reflecting plate 7 is completed, the reflecting plate 7 can be leveled through the sensing leveling structure, so as to ensure that the reflecting plate 7 can maintain a horizontal state. Furthermore, during the subsequent detection process, the heights of the laser emitted by the laser sensor 2 irradiated on the same annular area of the reflecting plate 7 are the same, thereby improving the accuracy of the subsequent detection of the laser sensor 2 and further improving the control precision of the gate plate 27;

[0038] When controlling an existing small sluice, when the hoist 30 is opened, the driving screw 28 can rise under the action of the hoist 30. At this time, the laser sensor 2 can measure the distance change amount and the time used for the distance change between the laser sensor 2 and the reflecting plate 7, so as to calculate the rising speed of the gate through the MCU in the control box 1, and then realize the intelligent control of the precise control of the gate plate 27;

[0039] After completing the control operation of the ram 27, the detection component can be disassembled from the sluice component and placed in the control box 1 and taken away, thus facilitating the intelligent control operation of the existing small sluice.

[0040] As Figures 3 to 8 , the sensing and leveling structure includes a sensing support rod 14, a ball 15, a glass water column 16, a spherical clamping strip 17 and a spherical protrusion 18. The sensing support rod 14 is vertically and fixedly connected to the bottom of the reflector 7. The number of sensing support rods 14 at the bottom of the same reflector 7 is at least two, and the sensing support rods 14 at the bottom of the reflector 7 are evenly distributed. The ball 15 is rotatably installed at the bottom end of the sensing support rod 14, and the ball 15 can be kept in contact with the inner wall of the arc-shaped groove of the fixed base 3. The glass water column 16 is horizontally installed on the top surface of the reflector 7, and there is a bubble in the glass water column 16. The spherical clamping strip 17 is fixedly connected to the inner top edge position of the arc-shaped groove. The spherical protrusion 18 is fixedly connected to the bottom of the reflector 7. The centers of the spherical clamping strip 17, the arc-shaped groove and the spherical protrusion 18 coincide, and the outer arc surface of the spherical protrusion 18 is kept in contact with the inner arc surface of the spherical clamping strip 17. The spherical clamping strip 17 has magnetism. The material of the spherical protrusion 18 is iron, and the length of the spherical clamping strip 17 is greater than the length of the spherical protrusion 18;

[0041] During the process of the laser sensor 2 cooperating with the reflector 7 to measure the vertical movement distance of the driving screw 28, if the reflector 7 is placed obliquely, it will cause a deviation in the distance where the laser sensor 2 shines on different positions at the top of the reflector 7 during the process of the laser sensor 2 rotating and rising along with the driving screw 28, thus affecting the accuracy of the detection by the laser sensor 2. At this time, through the setting of the sensing and leveling structure, after the two reflectors 7 are sleeved on the driving screw 28 by splicing the second plug 8 and the second jack 9, the two fixed bases 3 are placed on the top of the hoist 30 and spliced together. During the splicing process, as the two fixed bases 3 approach each other, the spherical clamping strips 17 on the two fixed bases 3 can gradually approach the spherical protrusions 18 at the bottoms of the two reflectors 7. When the two fixed bases 3 are completely spliced together, the sensing support rods 14 at the bottom of the reflector 7 can be in contact with the arc-shaped grooves of the fixed bases 3 through the balls 15, and the spherical protrusions 18 at the bottoms of the reflectors 7 can be rotatably clamped with the spherical clamping strips 17 of the fixed bases 3, so that the two reflectors 7 can deflect horizontally with the center of the spherical protrusion 18 as the center of the circle;

[0042] After the fixed base 3 and the reflector 7 are spliced together, it is possible to judge whether the reflector 7 is in a horizontal state by observing the bubbles in the glass water column 16. When the bubbles are not located in the middle position of the glass water column 16, the reflector 7 is not in a horizontal state. At this time, it is possible to press the side where the bubbles of the reflector 7 are biased, so as to horizontally adjust the reflector 7 until the bubbles in the glass water column 16 are at the middle of the glass water column 16. At this time, the reflector 7 can be in a horizontal state;

[0043] As the hoist 30 drives the driving screw 28 to rotate and rise, the laser sensor 2 fixed on the driving screw 28 can rotate and rise together with the driving screw 28. Since the reflector 7 is in a horizontal state, it is possible to ensure that the vertical distance of each position where the laser sensor 2 irradiates on the top of the reflector 7 is the same, thus avoiding the detection error of the laser sensor 2 caused by the inclination of the reflector 7, and further improving the accuracy of controlling the gate 27;

[0044] In addition, since the spherical clamping strip 17 has magnetism, when the horizontal adjustment of the reflector 7 is completed, the suction force of the spherical clamping strip 17 on the spherical protrusion 18 can make the reflector 7 remain stationary after adjusting the position, avoiding the deflection of the reflector 7 caused by the vibration generated during the operation of the hoist 30.

[0045] Such as Figures 3 to 9 , the centering structure includes a limiting block 19, an adjusting rod 20, a gear 21, a limiting rod 22, an adjusting plate 23 and a locking structure. The number of adjusting plates 23 is two, and the adjusting plate 23 is a semi-ring structure. The area where the adjusting plate 23 is located is always directly opposite to the area where the bottom probe of the laser sensor 2 is located, and the top surface of the adjusting plate 23 is smooth. An annular groove is formed on the top surface after the two reflectors 7 are spliced together, and the two adjusting plates 23 are rotatably installed in the annular groove. The bottom of the adjusting plate 23 is uniformly provided with teeth. The limiting block 19 is located inside the two spliced adjusting plates 23. The end of the limiting block 19 away from the adjusting rod 20 is designed as an arc surface. The number of limiting blocks 19 in the inner area of the two reflectors 7 is multiple, and the multiple limiting blocks 19 are evenly distributed in a ring. The adjusting rod 20 is vertically and rotatably connected to the side of the limiting block 19 close to the adjusting plate 23. An installation groove is formed at the position on the bottom inner wall of the annular groove opposite to the limiting block 19, and the end of the adjusting rod 20 away from the limiting block 19 is threadedly inserted into the installation groove. The gear 21 is fixedly sleeved on the end of the adjusting rod 20 away from the limiting block 19, and the gear 21 meshes with the teeth at the bottom of the adjusting plate 23. The limiting rod 22 is fixedly connected to the side of the limiting block 19 close to the adjusting rod 20. The limiting rod 22 is parallel to the adjusting rod 20, and the limiting rod 22 is slidably inserted into the inside of the reflector 7;

[0046] There are two locking structures, each located where the two ends of the two adjustment plates 23 are butted together. The locking structure includes two locating pins 24, with a connecting plate 25 fixedly connected between the top ends of the two locating pins 24. Locating holes 26 are provided at the top of the adjustment plates 23 near both ends, and the two locating pins 24 in the same locking structure are respectively inserted into two adjacent locating holes 26 on the two adjustment plates 23.

[0047] By providing a centering structure, after the fixed adjustment plate 23 is installed in the arc groove on the top of the fixed base 3, the two adjustment plates 23 are installed in the annular groove spliced together on the top of the two reflective plates 7. At this time, the teeth at the bottom of the adjustment plate 23 can keep meshing with the multiple gears 21, and then the two locking structures are respectively inserted between the two ends of the two adjustment plates 23, so that the two positioning pins 24 in the locking structure are respectively inserted into the positioning holes 26 on the two adjustment plates 23, thereby realizing the locking operation of the two adjustment plates 23. Then, while fixing the reflective plate 7 with one hand to keep it stationary, use the other hand to move the connecting plate 25, so that it drives the two adjustment plates 23 to rotate along the annular groove, and as the adjustment plate 23 rotates, the adjustment plate 23 can pass through its bottom The teeth drive the gears 21 on the multiple adjusting rods 20 to rotate synchronously, and as the gear 21 rotates, the adjusting rod 20 can push the limit block 19 to move in the direction close to the driving screw 28 under the limiting effect of the limit rod 22 on the limit block 19. During this process, the distance between each limit block 19 and the driving screw 28 can be observed, thereby adjusting the position of the fixed base 3 so that the multiple limit blocks 19 can eventually keep in contact with the surface of the driving screw 28 at the same time. At this time, the fixed base 3 and the adjusting plate 23 are both coaxial with the driving screw 28, thereby avoiding deviation in the position of the laser sensor 2 irradiated on the adjusting plate 23, thereby ensuring the accuracy of the laser sensor 2 in subsequent detection of the distance moved in the vertical direction of the driving screw 28 in cooperation with the adjusting plate 23;

[0048] After multiple limit blocks 19 are kept in contact with the drive screw 28, the adjustment plate 23 is then rotated in the opposite direction, so that the adjustment plate 23 can drive the adjustment rod 20 to rotate through the gear 21, and then the limit blocks 19 are separated from the surface of the drive screw 28 under the pull of the adjustment rod 20, avoiding the influence of the limit blocks 19 on the adjustment plate 23 when the drive screw 28 moves in the vertical direction.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
