Description

Technical Field

[0001] The invention belongs to the field of measuring equipment, and in particular relates to an automatic testing device for controllable water bleeding rate of low-strength materials. Background Art

[0002] Currently, the water bleeding rate of materials is usually measured by two methods: volume method and mass method.

[0003] The volumetric method of water seepage rate measurement requires starting the timer from the time the material is left to stand after being stirred with water. The newly mixed material is placed in a container and allowed to stand for a period of time to allow water to be secreted. The timer starts from the time it is left to stand and the water is sucked out with a pipette several times. The amount of water seepage is then determined by measuring the volume of the exuded water in the container. The water seepage rate is determined by calculating the ratio of the volume of the exuded water to the volume of the original water in the material.

[0004] The mass method for measuring water seepage rate is to place the newly mixed material (such as concrete mixture) into a specific container, let it stand for a period of time, and then use a pipette or other tools to collect the water that seeps out of the surface. The mass of the exuded water is determined by weighing it, and the water seepage rate is determined by calculating the ratio of the mass of the exuded water to the mass of the original water in the material.

[0005] However, most of the current devices used to measure material exudation require manual multi-step operations, and changes in ambient temperature have a significant impact on the experimental results. The measured values have large errors and are greatly affected by the subjective factors of the operator.

[0006] Therefore, a new design is needed that can reduce the measurement errors caused by environmental and human factors and can perform continuous and automatic measurement of water seepage rate. Summary of the Invention

[0055] The present invention will be further described below with reference to specific embodiments.

[0056] like Figure 1 and Figure 2 As shown, the present invention mainly includes a base, a hanging component, a lifting component, a conveying component and a feeding component. A support plate 501 is provided on one side of the base, and a feeding component is provided on the support plate 501. The top surface of the base and the top surface of the support plate 501 are jointly provided with a conveying component. The positions above the base and on both sides of the conveying component are respectively provided with a hanging component and a lifting component. The entire testing device is uniformly controlled by a control center 104 provided inside the base, so as to realize the automation of water seepage rate detection.

[0057] In this embodiment, the control center 104 is controlled by a single-chip microcomputer, which collects data from various electronic devices for processing, and then controls relays to drive the electronic devices to operate. The single-chip microcomputer and relays and other components are all integrated inside the base. There is no limit to the type and model of the single-chip microcomputer and each electronic device, as long as they can realize the functions required by this solution.

[0058] Four leveling devices 103 are provided at the bottom of the base, respectively provided at the four top corners of the base. The leveling devices 103 are specifically foot pads that can be adjusted in height by rotating the thread. The specific structure is relatively common, so it will not be described here in detail.

[0059] like Figure 1 and Figure 3 As shown, the suspension component is arranged above the base, and the suspension component mainly includes a support rod 201 and a mounting seat 202. The mounting seat 202 is arranged at the top end of the support rod 201 and extends to the top of the lifting component.

[0061] A temperature sensor 203, a heat dissipation component 204 and a heating tube 209 are provided on the side of the support rod 201, and a liftable water absorption component 205 and a distance measuring component 206 are provided on the lower surface of the mounting seat 202. The lifting component is mainly used to carry the sample tube 601, and the position where the water absorption component 205 and the distance measuring component 206 are arranged is directly above the position where the lifting component carries the sample tube 601.

[0062] The mounting base 202 and the support rod 201 are hollow structures that are interconnected, and the lines of each component can be connected from the inside of the support rod 201 and the mounting base 202 to the control center 104 inside the base.

[0063] like Figure 4 As shown, the water absorption component 205 includes an electric push rod 2051 and a micro water pump 2054. The electric push rod 2051 is arranged on the lower surface of the mounting base 202, and the telescopic end of the electric push rod 2051 is arranged downward. The telescopic end of the electric push rod 2051 is fixedly connected to a hollow tube 2052, and a pressure sensor probe 2053 is provided at the end of the hollow tube 2052. A micro water pump 2054 is provided on the side of the pressure sensor probe 2053, and a water hose 207 is connected to the side of the micro water pump 2054. A water tank 208 is provided on the base, and the other end of the water hose 207 is connected to the water tank 208. There are two sets of water absorption components 205. The movement direction of the driving end of the electric push rod 2051 in one set of water absorption components 205 is perpendicular to the mounting base 202, and the movement direction of the driving end of the electric push rod 2051 in the other set of water absorption components 205 is at a certain angle to the mounting base 202.

[0064] When absorbing water, the control center 104 drives the electric push rod 2051 to adjust the height of the hollow tube 2052, so that the hollow tube 2052 moves toward the direction of the sample cylinder 601. The pressure sensor at the end of the hollow tube 2052 is used to determine whether it contacts the surface of the material to be tested. When the pressure reaches a certain level, it indicates that it has contacted the surface of the material to be tested. At this time, the control center 104 issues a command to stop the movement of the electric push rod 2051 and start the micro water pump 2054 to pump water.

[0065] like Figure 5As shown, the heat dissipation component 204 mainly includes a packaging box 2041, which is arranged on the side of the support rod 201. The side of the packaging box 2041 facing the lifting component is an open structure, and the side of the packaging box 2041 away from the lifting component is provided with multiple heat dissipation holes. A hollow vertical rod 2042 is provided inside the packaging box 2041, and a fan motor 2043 is provided on the hollow vertical rod 2042. The output end of the fan motor 2043 is provided with fan blades 2044. The fan motor 2043 is electrically connected to the control center 104. The temperature sensor 203 is located above the heat dissipation component 204, and the heating pipe 209 is located below the heat dissipation component 204.

[0066] The control center 104 can control the opening and closing of the heat dissipation component 204 and the heating tube 209 according to the real-time temperature detected by the temperature sensor 203. When the temperature is too high, the heat dissipation component 204 is started for ventilation and cooling. When the temperature is too low, the heating tube 209 is started to heat up the surrounding environment, so that the detection environment can be maintained at a more appropriate level, reducing the impact of the ambient temperature on the water seepage rate detection.

[0067] In this embodiment, the distance measuring component 206 uses a laser distance measuring sensor to measure the distance between the material inside the sample tube 601 and the mounting seat 202 by laser, and calculates the actual volume of the material in combination with the pre-set various dimensional data of the sample tube 601.

[0068] like Figures 6 to 9As shown, the lifting component mainly includes a lifting base 301 and a table 3016.

[0074] like Figure 1 and Figure 8 As shown, the overall structure of the tray 3032 includes four vertical rods perpendicular to the upper surface of the electronic scale 303 and clamping blocks arranged at the top of the vertical rods. The clamping blocks arranged on the four vertical rods together form a shape that matches the bottom 604 of the sample tube 601.

[0080] The conveying component is mainly used to convey the sample tube 601, so that the sample tube 601 moves back and forth above the base and the support plate 501 to convey the material. In order to ensure the levelness between the support plate 501 and the base, a column foot 502 is provided under the support plate 501, and a column foot leveling device 503 is provided at the bottom of the column foot 502. The structure of the column foot leveling device 503 is the same as that of the leveling device 103. The support plate 501 is leveled by the column foot leveling device 503 so that the support plate 501 and the base are in the same plane.

[0081] like Figure 15 As shown, the feeding component is arranged above the support plate 501, and the feeding component includes a bracket seat 504 fixedly arranged above the support plate 501. A feeding funnel 505 is installed on the top of the bracket seat 504. When the sample cylinder 601 is moved by the conveying component to the bottom of the feeding funnel 505 of the support plate 501, the material can be fed into the sample cylinder 601 through the feeding funnel 505.

[0082] like Figure 2 As shown, the control center 104 is arranged inside the base, and several relays are also arranged inside the base. The control center 104 is electrically connected to the relay, and then electrically connected to the electric push rod 2051, the micro water pump 2054, the lifting platform motor 3014, the spiral lifting motor 302 and the electronic control equipment in other components through the relay, so as to uniformly control the electronic control components in other components, and each sensor is directly connected to the control center 104, such as the pressure sensor probe 2053, the temperature sensor 203, and the distance measuring component 206, and the collected data is directly processed by the control center 104.

[0083] like Figure 1As shown, a display screen 101 and a plurality of control buttons 102 are also provided on the periphery of the base. The display screen 101 can more intuitively show the temperature conditions and the mass and volume of the material to be tested. The control buttons 102 can be used to manually intervene in the operation of the entire device, such as start, stop, and reset, so that the staff can promptly deal with emergencies that occur during the normal operation of the device, such as excessive lifting of the lifting parts, failure of the conveying parts to be delivered to the right place, etc.

[0084] To better understand the working status of each component of the device during operation, the specific usage process of this embodiment is as follows. However, it should be noted that the time, angle and other factors used in the usage process are only used as a reference to demonstrate the usage process and do not constitute a limitation of this solution:

[0085] Before the experiment begins, the device is first adjusted to a horizontal level using the leveling device 103 under the base and the column foot leveling device 503 under the support plate 501 in conjunction with the spirit level 210. Then the device is turned on, the control center 104 is started, and the reset start button on the base is pressed to initialize the entire device. At this time, the hollow tube 2052 rises to the highest point to prevent the hollow tube 2052 from colliding with the sample tube 601.

[0086] The staff first installs the sample tube 601 on the conveying plate 407, and moves the sample tube 601 to the top of the electronic scale 303 through the conveying component, so that the base 604 of the sample tube 601 matches the position of the tray 3032 of the electronic scale 303. Then the lifting component rises, the electronic scale tray 3032 is engaged with the base 604 of the sample tube 601, and the sample tube 601 is lifted from the conveying plate 407. At the same time, the driving end of the stepper motor 3033 is docked with the tube cover 605 of the sample tube 601. The stepper motor 3033 rotates to rotate and open the cylinder cover 605 of the sample cylinder 601. After the cylinder cover 605 is opened, the lifting component descends, and the sample cylinder 601 falls back onto the conveying plate 407 again. By driving the conveying plate 407 of the conveying component to move to the bottom of the feeding funnel 505 set on the support plate 501, the mud to be tested is added to the sample cylinder 601 through the feeding funnel 505, and the system initialization and feeding work are completed.

[0087] After the feeding is completed, the conveying component brings the sample cylinder 601 to the top of the electronic scale 303 again, and rises again through the lifting component. The stepping motor 3033 rotates the cylinder cover 605 of the sample cylinder 601 to close it, and the sample cylinder 601 is left stationary for a while until the water is secreted.

[0088] The timing starts from the moment of standing still. Every 15 minutes during the first 30 minutes, the control center 104 sends a signal to the stepper motor 3033 and the water absorption component 205, rotates to open the cylinder cover 605 of the sample cylinder 601, controls the electric push rod 2051 of the water absorption component 205 perpendicular to the mounting base 202 to extend, and drives the micro water pump 2054 to move downward. When the pressure sensor probe 2053 detects a certain resistance (the resistance is greater than the buoyancy of the water), the pressure sensor probe 2053 transmits this signal to the control center 104, and then the control center 104 controls the electric push rod 2051 to stop moving and controls the micro water pump 2054 to start working. The micro water pump 2054 is turned off after 10S. During this period, the water sucked out by the micro water pump 2054 flows to the water tank 208 through the hose.

[0089] After 30 minutes, the tilting water absorption operation is performed every 30 minutes. When tilting water absorption, the control center 104 controls the spiral lifting motor 302 on the lifting component to rotate, and the internal internal threaded rod rotates to make the threaded nested rod 3021 rise along the direction of the guide groove inside the hollow cylinder 3022, and the upward movement of the push rod 3023 presses against the positioning groove 3036 below the slider 3035. Under the action of the push rod 3023, the slider 3035 inside the slide groove moves obliquely upward along the slide groove, pushing one end of the electronic scale base 3031 to tilt a certain angle. When it rises to the top, the model tube 601 tilts 20 degrees.

[0090] At this time, the control center 104 controls the electric push rod 2051 of the water absorbing component 205 which is at a certain angle to the mounting seat 202 to descend to perform water absorbing operation. The working principle of the water absorbing process is consistent with that of the water absorbing component 205 set perpendicular to the mounting seat 202.

[0091] When the tilting water absorption is completed, the control center 104 sends a signal to make the electric push rod 2051 rise, and at the same time controls the spiral lifting motor 302 to reverse, so that the sample cylinder 601 returns to the horizontal position. After each water absorption is completed, the control center 104 controls the laser distance sensor to measure the distance of the water-exuding material. The laser distance sensor transmits the obtained signal to the control center 104, and after conversion, the material volume and mass are output to the LCD screen 101.

[0092] During each water absorption operation, the control center 104 first controls the stepper motor 3033 to open the lid 605 of the sample cylinder 601 to absorb water and measure the sample. After the absorption and measurement are completed, the control center 104 controls the stepper motor 3033 to reverse and close the lid 605 of the sample cylinder 601. Simultaneously, after each distance measurement, the high-precision dedicated electronic scale 303 above the lifting component measures the mass of the exuded material in real time. In the previous preparatory step, when the sample cylinder 601 moves above the electronic scale 303, the lifting component activates the lifting platform motor 3014, causing the table 3016 to rise steadily. During the ascent of the high-precision dedicated electronic scale 303, the tray 3032 of the electronic scale 303 engages the support base 604 below the sample cylinder 601, freeing the sample cylinder 601 from the support of the conveyor plate 407. The electronic scale 303 continuously measures the mass of the material in the sample cylinder in real time, displaying the mass on the base LCD 101.

[0093] A plurality of control buttons 102 are installed on the side of the base, which can be used to manually control the electric push rod 2051 to absorb water and lift, control the operation of the spiral lifting motor 302, and control the operation of the stepping motor 3033. This ensures that when the entire device is working, the staff can manually intervene and promptly deal with various emergencies that occur during the operation of the device. Under normal working conditions, no additional control is required through the control button 102.

[0094] When the measurement of the entire process is completed, the sample cylinder 601 is sent to a position in the middle of the conveying device that is easy to remove. At this time, the sample cylinder 601 is removed, and the piston 602 inside the sample cylinder 601 is pushed by the push rod 603 under the sample cylinder 601 to more conveniently remove all the waste materials, and then the sample cylinder 601 is cleaned to avoid contamination.

[0095] In terms of environmental variables, the current ambient temperature is detected in real time by the temperature sensor 203 and displayed on the display screen 101 of the base. The specific height of the heat dissipation component 204 is the same as the height when the sample tube 601 is placed on the electronic scale 303. If the current ambient temperature is lower than the set temperature range, the control center 104 turns on the heating tube 209; if the current ambient temperature is higher than the set temperature range value, the control center 104 turns on the heat dissipation device until it reaches the set temperature range, at which time the control center 104 sends a signal to turn off the heat dissipation component 204 and the heating tube 209.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
