Description

Technical Field

[0001] The invention relates to the technical field of material level sensor detection, in particular to a semi-automatic sensor testing tool. Background Art

[0002] The material level sensor is a branch of the material level sensor, which is mainly used to detect and monitor the material storage level in the silo or tank. It can measure the material stacking height, quantity, shape and other information in the silo or tank to achieve automatic control, adjustment and management. It is widely used in industrial production, logistics, storage and transportation and other fields.

[0003] Since the material level sensor is mostly detected manually, when the material splashes, the splash detection speed is slow, which may cause false alarms. As a result, the rest of the functions of the material level sensor are normal, but the splash function has problems, and finally defective products are circulated in the market. To solve the above problems, the following solution is proposed, which is a semi-automatic sensor testing tool. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a semi-automatic sensor testing tool, comprising a bracket mechanism, a material level sensor, and a bottom shell platform arranged in the bracket mechanism, characterized in that it also includes:

[0005] The bracket mechanism is provided with an installation space for providing a basic mounting frame;

[0006] The fixing mechanism is provided with a movable clamping device for fixing the sensor for easy detection;

[0007] The sand throwing mechanism is provided with a loading device for filling various granular materials for detecting the sensor;

[0008] The outer wall of the bottom shell platform is fixedly connected to several arc-shaped plates, the outer walls of the several arc-shaped plates are fixedly connected to the material barrel, the outer wall of the bottom shell platform is fixedly connected to several rear plate brackets, the outer wall of the rear plate bracket is fixedly connected to the mobile platform, the inner wall of the mobile platform is rotatably connected to a threaded rod, and the outer wall of the threaded rod is engaged with the fixed platform.

[0009] Preferably, the support mechanism comprises:

[0010] A bracket assembly is fixedly connected to the inner wall of the bracket mechanism and is used to provide a basic fixing frame;

[0011] The moving component is fixedly connected to the outer wall of the bracket component and is used to provide moving power.

[0012] Preferably, the fixing mechanism comprises:

[0013] A fixed component, the fixed component is fixedly connected to the outer wall of the movable component and is used to provide a clamping fixed position;

[0014] The sliding component is fixedly connected to the bottom of the fixed component and is used to clamp the sensor for detection.

[0015] Preferably, the sand throwing mechanism comprises:

[0016] A detection component is fixedly connected to the outer wall of the bracket assembly and is used to provide a detection environment;

[0017] A power assembly is fixedly connected to the outer wall of the bracket assembly and is used to lift the sliding assembly.

[0018] Preferably, the bracket assembly includes a motor fixedly connected to the outer wall of the mobile platform. The curvature of the arc plate is utilized. When the material level sensor moves up and down due to the curvature of the arc plate, when passing through the rear end of the barrel to detect the splash function, because the two arc plates at the rear end are set close, when driving the material level sensor to move, it moves forward in a wavy line, so that the sand and gravel thrown by the arc plate hit different parts of the bottom of the material level sensor, avoiding different sensing responses at different positions of the bottom of the material level sensor, resulting in normal detection but false alarms during use.

[0019] Preferably, the moving assembly includes a plurality of fixed sliders fixedly connected to the outer wall of the fixed platform, the outer wall of the moving platform is fixedly connected to a plurality of slide bars, and the outer walls of the plurality of fixed sliders are meshedly connected with the outer walls of the slide bars.

[0020] Preferably, the fixing assembly includes a connecting block fixedly connected to the outer wall of the fixed platform, the outer wall of the connecting block is fixedly connected to a spring telescopic rod, the bottom of the spring telescopic rod is fixedly connected to an arc-shaped electrode piece, the bottom of the spring telescopic rod is fixedly connected to a splint, and the outer wall of the connecting block is fixedly connected to a fixed plate. By placing the material level sensor along the opening of the splint, the arc-shaped electrode piece is stuck into one end of the material level sensor electrical port, providing a basic weak current for the material level sensor, maintaining the normal use of the uploading light on the material level sensor, and at the same time, when the arc-shaped electrode piece is stuck into the material level sensor potential connection, it can prevent the material level sensor from shaking during detection. When taking it down, push the material level sensor forward to make the arc of its arc-shaped electrode piece shrink and pop out along the inner ring of the material level sensor, so as to avoid the tail end of the arc-shaped electrode piece pressing against the inner wall of the inner ring of the material level sensor when pulling it back, which makes it impossible to take out and damage the detection equipment.

[0021] Preferably, the sliding assembly includes an extension plate fixedly connected to the inner wall of the splint, support plates fixedly connected on both sides of the extension plate, rollers rotatably connected to the bottom of the support plates on both sides, and the rollers are fitly connected to the outer wall of the arc plate. By utilizing the force of the movement of the above-mentioned fixed platform, when the fixed platform drives the bottom assembly to move, the support plate moves, and the rollers rotatably connected at the bottom will squeeze the surface of the arc plate, thereby causing the spring telescopic rod to contract and the fixed assembly to move upward, causing the rollers to move along the surface of the arc plate, thereby preventing the material level sensor from hitting the outer wall and partition of the barrel, causing damage to the material level sensor and affecting the function of the material level sensor.

[0022] Preferably, the detection component includes a sand throwing wheel rotatably connected to the inner wall of the barrel, and the output shaft of the sand throwing wheel is fixedly connected to the gear. To solve the problem of inaccurate splash detection, when the fixed component drives the sliding component to move, it will pass through the barrel. When the motor is turned on and the threaded rod starts to rotate, the fixed platform will move forward along the slide bar, thereby driving the bottom component to move for detection. When passing through the barrel, the front end of the material level sensor will be immersed in the gravel filled in the barrel to test whether the material level sensor senses the presence of material. When the material level sensor is normal, it will emit a bright light, and when it is immersed in the sand, it will emit a bright light. There is no flashing light in the gravel. This indicates that there is an abnormality in the material level sensor. The material level sensor passes the rear end of the barrel. Since the gravel at the rear end is in a low position, it cannot directly touch the material level sensor. However, when the equipment moves to this point, the fixed plate will push the gear rod forward, thereby contacting the gear, causing the gear to rotate and control the rotation of the sand throwing wheel. When the sand throwing wheel rotates, it will drive the gravel upward and collide with the bottom of the material level sensor, preventing the material level sensor from detecting false alarms and avoiding the detection of splashing gravel and submerged gravel being consistent, which will cause the material level sensor to report false alarms during use.

[0023] Preferably, the power assembly includes a connecting plate fixedly connected to an end of the fixing plate away from the connecting block, an outer wall of the connecting plate is fixedly connected to a gear rod, and an outer wall of the gear rod is fit-connected to an outer wall of the bottom shell platform.

[0024] The present invention has the following beneficial effects:

[0025] (1) The present invention addresses the problem of inaccurate splash detection. When the material level sensor passes the rear end of the barrel, the sand and gravel at the rear end are in a low position and cannot directly touch the material level sensor. However, when the equipment moves to this point, the fixed plate will push the gear rod forward, thereby contacting the gear, causing the gear to rotate and controlling the rotation of the sand throwing wheel. When the sand throwing wheel rotates, it will drive the sand and gravel upward and collide with the bottom of the material level sensor, preventing the material level sensor from making a false alarm and avoiding the detection of splashing sand and gravel being consistent with that of submerged sand and gravel, which will cause the material level sensor to make a false alarm during use.

[0026] (2) The present invention utilizes the force of the movement of the above-mentioned fixed platform. When the fixed platform drives the bottom assembly to move, the roller connected to the bottom end of the support plate will squeeze the surface of the arc plate when the support plate moves, thereby causing the spring telescopic rod to contract and the fixed assembly to move upward, causing the roller to move along the surface of the arc plate, thereby preventing the material level sensor from hitting the outer wall and partition of the barrel, causing damage to the material level sensor and affecting the function of the material level sensor.

[0027] (3) The present invention utilizes the curvature of the arc plate. When the material level sensor moves up and down due to the curvature of the arc plate, when it passes through the rear end of the barrel to detect the splashing function, because the two arc plates at the rear end are set close to each other, when driving the material level sensor to move, it moves forward in a wavy line, so that the sand and gravel thrown by the arc plate hit different parts of the bottom of the material level sensor, avoiding different sensing responses at different positions of the bottom of the material level sensor, thereby causing the problem of normal detection but false alarm during use.

[0028] (4) The present invention utilizes the curvature of the arc plate. When the material level sensor moves up and down due to the curvature of the arc plate, when it passes through the rear end of the barrel to detect the splashing function, because the two arc plates at the rear end are set close to each other, when driving the material level sensor to move, it moves forward in a wavy line, so that the sand and gravel thrown by the arc plate hit different parts of the bottom of the material level sensor, avoiding different sensing responses at different positions of the bottom of the material level sensor, thereby causing the problem of normal detection but false alarm during use.

[0048] The outer wall of the bottom shell platform 111 is fixedly connected to a plurality of curved plates 312, the outer walls of the plurality of curved plates 312 are fixedly connected to the material barrel 311, the outer wall of the bottom shell platform 111 is fixedly connected to a plurality of rear plate brackets 112, the outer wall of the rear plate bracket 112 is fixedly connected to the movable platform 113, the inner wall of the movable platform 113 is rotatably connected to the threaded rod 121, and the outer wall of the threaded rod 121 is engaged and connected to the fixed platform 122.

[0049] The support mechanism 1 comprises:

[0050] The bracket assembly 11 is fixedly connected to the inner wall of the bracket mechanism 1 and is used to provide a basic fixing frame;

[0051] The moving assembly 12 is fixedly connected to the outer wall of the bracket assembly 11 and is used to provide moving power.

[0052] The fixing mechanism 2 comprises:

[0053] The fixed component 21 is fixedly connected to the outer wall of the moving component 12 to provide a clamping and fixing position;

[0054] The sliding component 22 is fixedly connected to the bottom of the fixed component 21 and is used to clamp the sensor for detection.

[0055] The sand throwing mechanism 3 comprises:

[0056] A detection component 31 is fixedly connected to the outer wall of the bracket component 11 and is used to provide a detection environment;

[0057] The power assembly 32 is fixedly connected to the outer wall of the bracket assembly 11 and is used to lift the sliding assembly 22 .

[0058] The bracket assembly 11 includes a motor 114 fixedly connected to the outer wall of the mobile platform 113. The curvature of the arc plate 312 is utilized. When the material level sensor 13 moves up and down due to the curvature of the arc plate 312, when passing through the rear end of the barrel 311 to detect the splashing function, because the two arc plates 312 at the rear end are set close to each other, when driving the material level sensor 13 to move, it moves forward in a wavy line, so that the sand and gravel thrown by the arc plate 312 hit different parts of the bottom of the material level sensor 13, avoiding different sensing responses at different positions of the bottom of the material level sensor 13, resulting in normal detection but false alarms during use.

[0059] For example 2, please refer to Figure 2-Figure 11 The present invention is a semi-automatic sensor testing tool. Based on Example 1, the moving component 12 includes a plurality of fixed sliders 123 fixedly connected to the outer wall of the fixed platform 122, and the outer wall of the moving platform 113 is fixedly connected with a plurality of slide bars 124, and the outer walls of the plurality of fixed sliders 123 are meshed with the outer walls of the slide bars 124.

[0060] The fixing assembly 21 includes a connecting block 211 fixedly connected to the outer wall of the fixing platform 122, the outer wall of the connecting block 211 is fixedly connected to a spring telescopic rod 212, the bottom of the spring telescopic rod 212 is fixedly connected to an arc-shaped electrode sheet 213, the bottom of the spring telescopic rod 212 is fixedly connected to a clamping plate 214, and the outer wall of the connecting block 211 is fixedly connected to a fixing plate 215. By placing the material level sensor 13 along the opening of the clamping plate 214, the arc-shaped electrode sheet 213 is stuck in one end of the electrical port of the material level sensor 13, The material level sensor 13 provides a basic weak current to maintain the normal use of the sensing light on the material level sensor 13. At the same time, when the arc-shaped electrode piece 213 is inserted into the material level sensor 13 and connected to the potential, it can prevent the material level sensor 13 from shaking during detection. When removing it, push the material level sensor 13 forward so that the arc of the arc-shaped electrode piece 213 shrinks and pops out along the inner ring of the material level sensor 13, so as to avoid the tail end of the arc-shaped electrode piece 213 being pressed against the inner wall of the inner ring of the material level sensor 13 when pulling it back, which makes it impossible to take it out and damage the detection equipment.

[0061] The sliding assembly 22 includes an extension plate 221 fixedly connected to the inner wall of the splint 214, and support plates 222 are fixedly connected on both sides of the extension plate 221. The bottom of the support plates 222 on both sides is rotatably connected to rollers 223, and the rollers 223 are fitly connected to the outer wall of the arc plate 312. By utilizing the force of the movement of the above-mentioned fixed platform 122, when the fixed platform 122 drives the bottom assembly to move, the support plate 222 moves, and the rollers 223 rotatably connected at the bottom will squeeze the surface of the arc plate 312, thereby causing the spring telescopic rod 212 to contract, and the fixed assembly 21 assembly to move upward, causing the rollers 223 to move along the surface of the arc plate 312, preventing the material level sensor 13 from hitting the outer wall and partition of the material barrel 311, causing damage to the material level sensor 13 and affecting the function of the material level sensor 13.

[0062] The detection component 31 includes a sand throwing wheel 313 rotatably connected to the inner wall of the barrel 311. The output shaft of the sand throwing wheel 313 is fixedly connected to the gear 314. To address the problem of inaccurate splash detection, when the fixed component 21 drives the sliding component 22 to move, it will pass through the barrel 311. When the motor 114 is turned on and the threaded rod 121 starts to rotate, the fixed platform 122 will move forward along the slide bar 124, thereby driving the bottom component to move for detection. When the material level sensor 13 passes through the barrel 311, the front end of the material level sensor 13 will be immersed in the gravel filled in the barrel 311 to test whether the material level sensor 13 senses the presence of material. When the material level sensor 13 is normal, it will emit a bright light. When the material level sensor 13 is immersed in the gravel and no light flashes, it means that there is an abnormality in the material level sensor 13. When the material level sensor 13 passes the rear end of the material barrel 311, the gravel at the rear end is in a low position and cannot directly touch the material level sensor 13. However, when the equipment moves to this point, the fixed plate 215 will push the gear rod 322 to move forward, thereby contacting the gear 314, causing the gear 314 to rotate and control the sand throwing wheel 313 to rotate. When the sand throwing wheel 313 rotates, it will drive the gravel to be thrown upward and collide with the bottom of the material level sensor 13, preventing the material level sensor 13 from detecting false alarms and avoiding the splashing gravel and the detection when the gravel is immersed in the gravel, which will cause the material level sensor 13 to detect false alarms during use.

[0063] The power assembly 32 includes a connecting plate 321 fixedly connected to the end of the fixing plate 215 away from the connecting block 211 . The outer wall of the connecting plate 321 is fixedly connected to a gear rod 322 . The outer wall of the gear rod 322 is in close contact with the outer wall of the bottom shell platform 111 .

[0064] A specific application of this embodiment is: before use, the front section of the material barrel 311 is filled with sand and gravel specially used for detection, and then filled with sand and gravel that is highly parallel to the sand throwing wheel 313, or a single material of the detection product is filled and tested, the power of the equipment is turned on, the material level sensor 13 is manually placed on the clamping plate 214, and the equipment is turned on. When the fixed component 21 drives the sliding component 22 to move, it will pass through the material barrel 311. When the motor 114 is turned on and the threaded rod 121 starts to rotate, the fixed platform 122 will move forward along the slide bar 124, thereby driving the bottom component to move for detection. When the material level sensor 13 passes through the material barrel 311, the front end of the material level sensor 13 will be immersed in the sand and gravel filled in the material barrel 311 to test whether the material level sensor 13 senses the presence of material. When the material level sensor 13 is normal, it will emit a bright light, and when it is immersed in the sand and gravel, it will not flash. The light is bright, which means that there is an abnormality in the material level sensor 13. The material level sensor 13 passes the rear end of the material barrel 311. Since the sand at the rear end is in a low position, it cannot directly touch the material level sensor 13. However, when the equipment moves to this point, the fixed plate 215 will push the gear rod 322 to move forward, thereby contacting the gear 314, causing the gear 314 to rotate, controlling the rotation of the sand throwing wheel 313. When the sand throwing wheel 313 rotates, it will drive the sand to be thrown upward and collide with the bottom of the material level sensor 13, preventing the material level sensor 13 from detecting false alarms and avoiding the same detection when the splashing sand is consistent with the detection when the sand is immersed, thereby causing the material level sensor 13 to detect false alarms during use. At the same time, the rear end bottom of the material barrel 311 is set to a slope. The thrown sand will fall to the bottom when it collides with the material level sensor 13, and will roll back to the sand throwing wheel 313 through the slope setting for reuse.

[0065] By utilizing the force of the movement of the above-mentioned fixed platform 122, when the fixed platform 122 drives the bottom assembly to move, the roller 223 connected to the bottom end of the support plate 222 will be squeezed onto the surface of the arc plate 312 when the support plate 222 moves, thereby causing the spring telescopic rod 212 to contract, and the fixed assembly 21 assembly to move upward, causing the roller 223 to move along the surface of the arc plate 312, thereby preventing the material level sensor 13 from hitting the outer wall and partition of the barrel 311, causing damage to the material level sensor 13 and affecting the function of the material level sensor 13.

[0066] By utilizing the curvature of the arc plate 312, when the material level sensor 13 moves up and down due to the curvature of the arc plate 312, when passing through the rear end of the barrel 311 to detect the splash function, because the two arc plates 312 at the rear end are set close to each other, when driving the material level sensor 13 to move, it moves forward in a wavy line, causing the sand and gravel thrown by the arc plate 312 to hit different parts of the bottom of the material level sensor 13, avoiding different sensor responses at different positions of the bottom of the material level sensor 13, thereby avoiding the problem of normal detection but false alarm during use.

[0067] By placing the material level sensor 13 along the opening of the clamping plate 214, the arc-shaped electrode piece 213 is stuck into one end of the material level sensor 13 electrical port, providing the material level sensor 13 with a basic weak current, and maintaining the normal use of the sensing light on the material level sensor 13. At the same time, when the arc-shaped electrode piece 213 is stuck into the material level sensor 13 to connect the potential, it can prevent the material level sensor 13 from shaking during detection. When removing the material level sensor 13, push the material level sensor 13 forward to make the arc of the arc-shaped electrode piece 213 shrink and pop out along the inner ring of the material level sensor 13, so as to avoid the tail end of the arc-shaped electrode piece 213 being pressed against the inner wall of the inner ring of the material level sensor 13 when pulling it back, which makes it impossible to take out and damage the detection equipment.
