Description

Technical Field

[0001] The utility model relates to the technical field of mud performance detection, in particular to a mud multi-parameter automatic detection device. Background Art

[0002] At present, in civil engineering, the quality index of mud is related to the quality and safety of buildings. For example, in the construction of underground continuous walls and bored piles and other foundations, mud is required for wall protection construction. The three properties of mud, namely specific gravity, sand content and viscosity, have a great relationship with the quality of wall protection and the molding quality of wall (pile body). Therefore, the three properties of mud should be tested frequently during the on-site construction process to ensure that the three properties meet the requirements of the specifications and adapt to the geological conditions of on-site construction, so as to ensure the quality and index of mud, ensure the quality of buildings and reduce engineering accidents.

[0003] In current construction, mud buckets are mostly used to manually sample mud in the tank or hole, and then three tests are conducted on the ground using three different instruments: a traditional mud density meter, a funnel viscometer, and a sand content meter to detect the three properties of the mud. This method of sampling is highly dangerous and complicated, and requires the cooperation of multiple testers. It is time-consuming, labor-intensive, and inefficient. At the same time, due to the uneven operating levels of the surveyors and the great influence of environmental factors, manual judgment of the mud indicators in the hole may result in a large deviation between the measurement results and the actual results. The detection accuracy of the mud performance is not high, which affects the pile foundation mud detection standards and quality, thereby reducing the overall construction quality of the pile foundation and burying construction quality risks for the entire project. In addition, due to the complex construction site environment, personal injury may also occur. Utility Model Content

DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0023] like Figure 1As shown, the mud multi-parameter automatic detection device of this embodiment includes a detection box 100, a specific gravity detection module 200, a viscosity detection module 300 and a sand content detection module 400, a slurry extraction device 500, a water extraction device 600 and a controller. The specific gravity detection module 200, the viscosity detection module 300 and the sand content detection module 400 are arranged vertically from top to bottom in the detection box 100, and a modular design is adopted, which is convenient for on-site assembly, installation and disassembly, and easy to carry; and the three detection modules of the specific gravity detection module 200, the viscosity detection module 300 and the sand content detection module 400 are integrated, so that the three parameters of the specific gravity, viscosity and sand content of the mud can be detected at one time, which is convenient and fast. The slurry collecting device 500 and the water collecting device 600 are arranged outside the detection box 100 and are electrically connected to the electric pump. The slurry collecting device 500 and the water collecting device 600 are located above the specific gravity detection module 200. The power provided by the electric pump can enable the slurry collecting device 500 to extract the mud to be tested and transport it to the specific gravity detection module 200 to realize automatic sampling. The slurry collecting device 500 adopts an electric pump, which can automatically extract the deep mud of the pile foundation, without the need for manual cooperation with the drilling rig to obtain the mud, reducing the risk of on-site managers and testers transferring to the pile foundation and mechanical injuries from the site, and has higher safety; the output port of the slurry collecting device 500 is connected to the input port of the specific gravity detection module 200, and is used to extract mud. The slurry is transported to the specific gravity detection module 200, the viscosity detection module 300 and the sand content detection module 400 in sequence to measure the properties of the slurry. The input port of the water intake device 600 is also connected to the input port of the specific gravity detection module 200, so as to extract clean water and transport the clean water to the specific gravity detection module 200, the viscosity detection module 300 and the sand content detection module 400 for filtration and cleaning. A partition 101 is arranged in the detection box 100, and the partition 101 is arranged between the specific gravity detection module 200 and the viscosity detection module 300 to support the specific gravity detection module 200, so that the weight of the slurry to be tested in the specific gravity detection module 200 is fully borne by the partition 101, thereby facilitating the measurement of the slurry. Accurate measurement of slurry specific gravity; the sand content detection module 400 includes a filter bin 401 and a sand content detector 402, the sand content detector 402 is placed below the filter bin 401 and the input port of the sand content detector 402 is connected to the bottom of the filter bin 401, for cleaning the mud filtered in the filter bin 401 and flushing it into the sand content detector 402 for measuring the sand content, a filter port is provided on the side wall at the bottom of the filter bin 401, a screen 4011 is installed on the filter port, so that the mud to be tested is filtered through the screen 4011 in the filter bin 401, and the filter port is connected to the outside of the detection box 100, so that the filtered slurry water can flow to the outside of the device to avoid affecting the measurement in the detection box 100.Preferably, the device also includes a controller, which is electrically connected to the slurry extraction device 500, the water extraction device 600, the specific gravity detection module 200, the viscosity detection module 300 and the sand content detection module 400. The controller controls the opening and closing of each module to realize automatic synchronous measurement of the specific gravity, viscosity and sand content of the mud or measure them separately, and controls each module to realize automatic cleaning function after the measurement. At the same time, it can receive and record the detection data and display it in real time.

[0024] Before measurement, the device is calibrated by supplying clean water into the device. Specifically, the water intake device 600 is turned on, and clean water is supplied to the specific gravity detection module 200 and the viscosity detection module 300 in turn. When the measured specific gravity and viscosity of the clean water meet the requirements, the calibration of the device is completed, and the water intake device 600 is closed. Then, the mud properties are measured. Specifically, the slurry taking device 500 is turned on, and the slurry taking device 500 is used to transport the extracted mud to be tested to the specific gravity detection module 200 for specific gravity measurement. When the extracted mud to be tested reaches a preset volume, the slurry taking device 500 is turned off, and the mud to be tested is transported from the specific gravity detection module 200 to the viscosity detection module 300 for viscosity measurement. After the viscosity measurement is completed, the mud in the viscosity detection module 300 is transported to the filter bin 401 of the sand content detection module 400. At the same time, the water taking device 600 is turned on, the filter port is opened, and the water taking device 600 is controlled by the controller to add water to the filter bin 401 so that the mud in the filter bin 401 can be filtered. The sieve 4011 on the side wall is used for filtering, that is, the filtered slurry is discharged from the filter port to the outside of the detection box 100, and the filtered mud residue is attached to the surface of the sieve 4011 located on one side of the filter chamber 401. After the filtering is completed, the filter port is closed, and the bottom of the filter chamber 401 is connected to the input port of the sand content detector 402 through the controller, and water is continuously added to the filter chamber 401 to flush the mud residue on the sieve 4011 in the filter chamber 401 into the sand content detector 402. After the liquid level in the sand content detector 402 reaches a certain height, the water intake device 600 is controlled to be closed, and the reading of the sand content detector 402 after standing is the measured sand content value of the mud. At this point, the device completes the measurement of the specific gravity, viscosity and sand content of the mud. Finally, the water intake device 600 is started again to deliver clean water into the detection box 100, so that the clean water flows through the specific gravity detection module 200, the viscosity detection module 300 and the sand content detection module 400 to clean the device. After cleaning, prepare for the next measurement.

[0025] like Figure 1As shown, the specific gravity detection module 200 includes a specific gravity bin 201 and a specific gravity sensor, the specific gravity bin 201 is used to receive a preset volume of mud to be tested delivered by the slurry taking device 500, and the specific gravity sensor is used to measure the mud to be tested in the specific gravity bin 201; the specific gravity bin 201 is placed on the partition 101, so that the partition 101 bears the total weight of the specific gravity bin 201 and the mud to be tested in the specific gravity bin 201, and the gravity sensor 202 is arranged between the specific gravity bin 201 and the partition 101 and installed at the bottom of the specific gravity bin 201, so that the gravity sensor 202 can sense the total weight of the mud to be tested in the specific gravity bin 201, so as to accurately sense the weight of the mud to be tested in the specific gravity bin 201. Preferably, the gravity bin 201 includes a cylindrical upper bin body and a conical lower bin body, so that the diameter of the upper opening of the gravity bin 201 is larger than the diameter of the lower opening. On the one hand, the upper end of the gravity bin 201 can receive all the mud to be tested delivered by the slurry taking device 500 to avoid mud loss; on the other hand, the setting of the conical lower bin body can guide the flow of mud, so that the speed at which the mud to be tested in the gravity bin 201 flows out from the lower end is accelerated, thereby improving the detection efficiency. The gravity sensor 202 is electrically connected to the controller, and the gravity sensor 202 plays the role of collecting and transmitting the weight of the injected mud. The electrical connection with the controller can transmit the weight of the mud measured by the gravity sensor 202 to the controller, and the measured specific gravity value is displayed and stored by the controller, thereby realizing the specific gravity measurement of the mud, and remote monitoring and data storage can be implemented for easy later reference. The output port of the gravity bin 201 can be penetrated through the partition 101, or can be set on the side of the gravity bin 201, and is connected to the viscosity detection module 300 below through a pipeline. A first solenoid valve 203 is installed on the output port or the connecting pipeline, and the controller is electrically connected to the first solenoid valve 203 to control the opening and closing of the first solenoid valve 203. When in use, before the gravity detection module 200 measures the specific gravity of the mud, the controller controls the first solenoid valve 203 to close, and the slurry taking device 500 transports the mud to be measured into the gravity bin 201. When the mud to be measured received in the gravity bin 201 reaches a preset volume, the slurry taking device 500 is closed, and then the gravity sensor 202 starts to measure the weight of the mud in the gravity bin 201, and then the measured value is transmitted to the controller for recording and display, thereby completing the measurement of the mud specific gravity. After the specific gravity measurement is completed, the controller opens the first solenoid valve 203, so that the mud in the specific gravity bin 201 flows from the output port of the specific gravity bin 201 to the viscosity detection module 300 below for viscosity measurement. Optionally, an electronic scale can also be used to measure the specific gravity. Preferably, the gravity sensor 202 measures the total weight of the specific gravity bin 201 and the mud to be measured. Since the mass of the mud to be measured is much heavier than that of the specific gravity bin 201, it can be approximately considered that the gravity sensor 202 measures the weight of the mud to be measured.Of course, in order to make the measurement result more accurate, the weight of the specific gravity bin 201 may be pre-set in the controller, and the weight of the specific gravity bin 201 may be subtracted from the weight measured by the gravity sensor 202 to obtain the weight of the mud to be measured.

[0026] like Figure 1 As shown, the viscosity detection module 300 includes a viscosity detector 301, a first liquid level sensor 302 and a timer 303. The viscosity detector 301 includes an input port arranged in the direction of the specific gravity bin 201 and an output port arranged in the direction of the sand content detection module 400. The input port is connected to the output port of the specific gravity bin 201 through a flexible tube, and a second solenoid valve 304 is arranged on the output port. The viscosity detector 301 is fixedly installed in the detection box 100 to avoid its own gravity from affecting the specific gravity bin 201 above and affecting the measurement of the specific gravity of the mud by the specific gravity detection module 200; the first liquid level sensor 302 is installed at a preset volume on the inner wall of the viscosity detector 301. Specifically, the liquid level sensor is arranged at a volume of 500ml on the inner wall of the viscosity detector 301. The first liquid level sensor 302 has waterproof and anti-corrosion properties and is fixed by waterproof glue. The timer 303 can be an electronic stopwatch, which is arranged on the outer wall of the viscosity detector 301. The first liquid level sensor 302, the timer 303, the first electromagnetic valve 203 and the second electromagnetic valve 304 are all electrically connected to the controller. When in use, after the specific gravity detection module 200 completes the specific gravity measurement of the mud, the second electromagnetic valve 304 is in a closed state. At this time, the first electromagnetic valve 203 on the specific gravity bin 201 is opened by the controller, so that the mud in the specific gravity bin 201 flows into the viscosity detector 301. At the same time, the controller starts the timer 303, so that the timer 303 starts timing when the first electromagnetic valve 203 is opened. When the mud in the viscosity detector 301 reaches 500ml, the liquid level sensor sends a signal to the controller to stop the timer 303. The time recorded by the timer 303 is the viscosity of the mud to be measured. Preferably, the viscosity detector 301 is a measuring cylinder marked with a 700ml scale.

[0027] like Figure 1As shown, the filter chamber 401 is in the shape of a cone, including an input port arranged in the direction of the viscosity detector 301 and a slag flushing port arranged in the direction of the sand content detector 402. The diameter of the input port is larger than the diameter of the slag flushing port, so as to receive the mud to be tested transported in the viscosity detector 301. The setting of the cone can guide the flow of the mud, accelerate the flow of the mud in the filter chamber 401, and improve the detection efficiency; the filter port is arranged on the side wall at the bottom of the filter chamber 401, and a screen 4011 is installed on the filter port for filtering the mud in the filter chamber 401. The filter port is connected to the outside of the detection box 100 through a filter tube 4012, so that the mud in the filter chamber 401 is filtered through the screen 4011, and the slurry water is filtered out from the filter chamber 401. The pipe 4012 flows to the outside of the detection box 100, and the mud residue is left on the surface of the screen 4011 facing the filter bin 401. The filter pipe 4012 is provided with a fourth solenoid valve 404, which is electrically connected to the controller, and the opening and closing of the fourth solenoid valve 404 is controlled by the controller; the slag flushing port is provided at the bottom of the filter bin 401, and is connected to the sand content detector 402, which is used to flush the mud residue attached to the screen 4011 from the slag flushing port to the sand content detector 402 to measure the sand content after the slurry inside is filtered. The slag flushing port is provided with a third solenoid valve 403, which is electrically connected to the controller, and the opening and closing of the third solenoid valve 403 is controlled by the controller. Optionally, the filter pipe 4012 is a flexible pipe. During use, after the viscosity detection module 300 completes the viscosity measurement, the controller opens the second solenoid valve 304 on the viscosity detector 301 and the fourth solenoid valve 404 on the filter tube 4012 at the same time, and the third solenoid valve 403 remains closed at this time, so that the mud to be tested in the viscosity detector 301 flows into the filter bin 401 and is filtered through the screen 4011, and at the same time, the water intake device 600 is started to add water to the filter bin 401 to assist in filtering, so that the mud residue after filtering the mud to be tested adheres to the inner surface of the screen 4011; after the filtering is completed, the fourth solenoid valve 404 is closed, and the third solenoid valve 403 is opened, and the water adding operation of the water intake device 600 is maintained, so that the mud residue on the screen 4011 flows to the sand content detector 402 under the action of the water flow to measure the sand content.

[0028] like Figure 1As shown, a second liquid level sensor is provided at the top of the inner wall of the sand content detector 402, and the controller is electrically connected to the third solenoid valve 403 and the water intake device 600, and is used to control the third solenoid valve 403 to open and simultaneously start the water intake device 600 for cleaning, and the controller is electrically connected to the second liquid level sensor, and is used to control the third solenoid valve 403 to close when receiving the liquid level signal sent by the second liquid level sensor. During use, after the mud to be tested in the filter bin 401 is filtered, the fourth solenoid valve 404 is closed by the controller, the third solenoid valve 403 is opened, and the water adding operation of the water intake device 600 is maintained, so that the mud residue on the screen 4011 flows into the sand content detector 402 under the action of the water flow. The sand content detector 402 senses the liquid level through the second liquid level sensor at the top, so that the second liquid level sensor sends the sensing signal to the controller, and the water intake device 600 is controlled to be closed by the controller. The sand content detector 402 is left to stand until the internal mud residue is stable at the bottom, and the value read on the sand content detector 402 is the measured sand content of the mud.

[0029] like Figure 1 As shown, a protective tube 700 is connected between the specific gravity bin 201 and the viscosity detector 301, between the viscosity detector 301 and the filter bin 401, and between the filter bin 401 and the sand content detector 402 to prevent the mud to be tested from splashing out.
