Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mud detection, and particularly relates to a mud hydrometer. Background Art
[0002] The water-cement ratio of cement slurry refers to the ratio of the weight of water to the weight of cement in the slurry. It is an important factor determining the strength of the composite foundation of cement mixing piles and the strength of the foundation reinforced by high-pressure jet grouting, and is an important content for quality inspectors and supervisors to control the construction quality.
[0003] Generally, the water-cement ratio of cement slurry needs to be measured using a cement slurry hydrometer. The traditional cement slurry specific gravity needs to be measured under the condition that the slurry is flowing. The measuring device generally includes a box body and a hydrometer arranged at the bottom of the box body. When in use, it is necessary to continuously pump the slurry into the box body through the liquid inlet pipe, and at the same time, continuously pump out the slurry in the box body through the liquid outlet pipe to keep the liquid level of the slurry always maintained at the specified scale position of the box body. In order to avoid problems such as the slurry solidification during the measurement process and the influence of the slurry flow on the hydrometer, the flow rate of the slurry is usually relatively large, which results in the need to set a relatively large volume for the box body. The overall movement of the measuring device is difficult, and a lifting tool or a carrier needs to be used for movement, which is extremely inconvenient during use and is not conducive to the on-site measurement of the water-cement ratio; moreover, due to the large volume of the box body, the cleaning work after measurement is also more difficult, and the overall use cost of the device remains high. Summary of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0046] It should be noted that the orientation or positional relationship indicated by terms such as "length", "width", "height", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "head", "tail", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model.
[0047] It should also be noted that unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", "setting", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0048] In addition, the terms "first" and "second" are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, the meanings of "a plurality" and "several" are two or more, unless otherwise specifically defined.
[0049] Please refer to Figures 1 to 7 simultaneously. Now, the mud hydrometer provided by the present utility model will be described. It includes a handheld housing 1, a cylindrical material holding container 2, a pressure sensor 3, and a display component 4; the handheld housing 1 is provided with a receiving cavity 11 with an upward opening; the cylindrical material holding container 2 is fixed at the opening of the receiving cavity 11, a feed port is formed at the top of the material holding container 2, and an opening is provided at the bottom of the material holding container 2; the pressure sensor 3 is arranged at the bottom of the receiving cavity 11, a detection surface 31 is provided on the upper surface of the pressure sensor 3, and the detection surface 31 seals the bottom opening of the material holding container 2; the display component 4 is arranged on the handheld housing 1 and is communicatively connected to the pressure sensor 3.
[0050] It should be noted that the detection surface 31 only measures the weight of the mud liquid in the material holding container 2. Using the condition that the inner cavity volume of the material holding container 2 is known, the volume of the mud liquid can be obtained, and the density of the mud liquid can be deduced through a formula, thereby obtaining the water-cement ratio of the cement slurry.
[0051] It should be noted that the size of the detection surface 31 is the same as the size of the bottom opening of the material holding container 2, so that when the pressure sensor 3 and the material holding container 2 are docked, the detection surface 31 just seals the bottom opening of the material holding container 2.
[0052] It should be noted that this device is a handheld hydrometer, which can be easily moved by a single person and is convenient to carry compared with the existing large-scale hydrometers.
[0053] It should be noted that in this application, the mud liquid is injected into the material holding container 2, and the pressure sensor 2 senses the weight of the mud liquid.
[0054] It should be noted that the material holding container 2 is a cylindrical quantitative container, and the overall weight of the mud liquid will completely fall on the detection surface 31. This application measures the specific gravity of the static mud liquid, and the mud liquid can be weighed multiple times to take the average value of multiple data.
[0055] It should be noted that in this application, multi-region sampling of the mud liquid is performed, and the specific gravity of the mud liquid in each region is measured. Since the amount of mud liquid used for sampling by the device is small, multi-region sampling will not increase the working intensity of the staff.
[0056] It should be noted that in this application, the mud liquid can be sampled at different time periods respectively.
[0057] Compared with the prior art, the mud hydrometer provided in this embodiment is provided with a handheld housing 1. Inside the handheld housing 1, a material holding container 2, a pressure sensor 3 and a display component 4 are installed. A small amount of mud liquid is taken and placed in the material holding container 2, and the data obtained by the pressure sensor 3 is displayed on the display component 4, which is convenient to operate. The mud hydrometer of this application is small in size, can be held by hand, is convenient to carry, does not require the assistance of large lifting tools for transportation, saves transportation costs, and can also reduce the use difficulty and improve the measurement efficiency; at the same time, the volume of the material holding container 2 is small, the amount of mud used is greatly reduced, the loss of the mud liquid generated by the measurement is less, and the material holding container 2 is relatively easy to clean after use, and the difficulty of later maintenance of the mud hydrometer is low, reducing the maintenance cost.
[0058] In some embodiments, refer to Figure 5 , a dust-proof cover 13 is detachably covered on the feed inlet. The dust-proof cover 13 can cover the feed inlet and the material holding container 2, protect the material holding container 2 during transportation, and prevent the material holding container 2 and the detection surface 31 from being damaged by bumping or being contaminated with dust, etc., which affects the determination quality.
[0059] As an assembly method of the dust-proof cover 13 and the feed inlet, hinge joints and buckle joints are respectively provided on the opposite sides of the dust-proof cover 13. On the handheld housing 1, hinge protrusions are provided corresponding to the hinge joints, and buckle rings are provided corresponding to the buckle joints; the hinge joints and the hinge protrusions are always hinged together, and the hinge axis is parallel to the surface of the handheld housing 1 where the feed inlet is provided; when the dust-proof cover 13 is buckled to the feed inlet, the buckle ring and the buckle joint are buckled to realize sealing the feed inlet with the dust-proof cover 13.
[0060] As another assembly method of the dust-proof cover 13 and the feed inlet, a threaded ring is connected to the side surface of the dust-proof cover 13 facing the feed inlet, and a thread is correspondingly formed on the outer wall of the feed inlet. The threaded ring and the inner wall of the feed inlet are in threaded cooperation to realize the sealed connection of the dust-proof cover 13 and the feed inlet.
[0061] In some embodiments, refer to Figures 1 to 3 , the size of the detection surface 31 is adapted to the bottom opening size of the material holding container 2. The volume of the material holding container 21 remains unchanged, and the volume of the mud liquid received is certain. The detection surface 31 has the same size as the bottom opening of the material holding container 2, and the detection surface 31 is only affected by the mud liquid and stressed, which improves the accuracy and credibility of the final data.
[0062] In some embodiments, refer to Figure 3, the display component 4 includes a display screen 41 and a data processor 42. The display screen 41 is provided on the handheld housing 1; the data processor 42 is provided inside the handheld housing 1 and is communicatively connected to the pressure sensor 3 and the display screen 41 respectively. The data processor 42 receives data from the pressure sensor 3, processes and stores it. The data processor 42 can feedback the processed data to the display screen 41 for intuitive display, facilitating the staff to read the data; the setting of the display screen 41 enables the staff to more intuitively observe the measurement results and improves the detection efficiency.
[0063] In some embodiments, referring to Figure 2 , the mud hydrometer further includes a data output component 5, and the data output component 5 includes an operation keyboard 51 and a ticket printer 52. The operation keyboard 51 is provided on the handheld housing 1, and the operation keyboard 51 is communicatively connected to the data processor 42; the ticket printer 52 is provided inside the handheld housing 1 and is communicatively connected to the data processor 42. An outlet is provided on one side of the ticket printer 52 away from the material holding container 2.
[0064] The data output component 5 provided in this embodiment is simple to manufacture, can make full use of the space inside the handheld housing 1. The operation keyboard 51 enables the staff to input a printing command into the data processor 42. The data processor 42 controls the ticket printer 52 to print out the corresponding data sheet for the staff to use according to the printing command. The overall structure is simple, reducing the work difficulty of the staff.
[0065] It should be noted that the structure of the ticket printer 52 is similar to the structure of the ticket printer in the prior art. That is to say, it is the prior art that the ticket printer 52 can receive data for printing, which will not be elaborated here.
[0066] In some embodiments, referring to Figure 1 and Figure 2 , the ticket printer 52 is further provided with an output interface 521, and the output interface 521 is connected to a printer through a data line. The output interface 521 is connected to the printer through a data line, and various styles of files can be printed through the printer, increasing the functional diversity of the device; moreover, when the number of tickets stored in the ticket printer 52 is insufficient, connecting the printer can continue printing to ensure the normal progress of the mud specific gravity detection work.
[0067] In some embodiments, referring to Figure 1 and Figure 2, the mud hydrometer is also provided with a display lamp 7. The display lamp 7 is arranged on the handheld housing 1 and is electrically connected to the data processor 42. The staff can input standard data into the data processor 42 through the operation keyboard 51, and the data processor 42 stores the data to compare the actual measurement data with the standard data. The data processor 42 controls the display lamp 7 to emit light according to the comparison result, enabling the staff to more intuitively judge the actual situation of the water-mud ratio of the mud liquid. Specifically, when implemented, if the actual measurement data does not conform to the standard data (for example, the actual measurement data is higher or lower than the standard data), the data processor 42 controls the display lamp 7 to emit light of a specified color to remind the staff to adjust the composition of the mud liquid accordingly.
[0068] Specifically, when implemented, the staff inputs the water-mud ratio value of the standard mud from the operation keyboard 51, pours a fixed amount of mud liquid into the material containing container 2, and the pressure sensor 3 transports the real-time water-mud ratio value into the data processor 42 for comparison in the data processor 32.
[0069] Specifically, when implemented, the display lamp 7 has two groups of different lights. Taking the red lamp and the blue lamp as an example, if the actual measurement data is greater than the standard data, the display lamp 7 emits red light; if the actual measurement data is less than the standard data, the display lamp 7 emits blue light, enabling the staff to more clearly and quickly judge the specific gravity of the mud.
[0070] As a lighting mode of the display lamp 7, there are two display lamps 7, one emits green light and the other emits red light. The two display lamps 7 are respectively electrically connected to the data processor 42. If the actual measurement data is greater than the standard data, the red display lamp 7 emits light and the green display lamp 7 does not emit light; if the actual measurement data is less than the standard data, the green display lamp 7 emits green light and the red display lamp 7 does not emit light.
[0071] In some embodiments, refer to Figure 1 , the handheld housing 1 is also provided with a power interface 12. The power interface 12 is respectively electrically connected to the pressure sensor 3 and the display component 4. The power interface 12 can be externally connected to a power source to enable the pressure sensor 3 and the display component 4 to operate normally.
[0072] In some embodiments, refer to Figure 4 , a replacement cylinder 6 is inserted into the material containing container 2. The axis of the replacement cylinder 6 coincides with the axis of the material containing container 2, and the outer wall of the replacement cylinder 6 fits with the inner wall of the material containing container 2. The detection surface 31 seals the bottom opening of the replacement cylinder 6.
[0073] In this embodiment, the replacement cylinder 6 is used as the container for the mud liquid. By replacing the replacement cylinder 6 with different major axes, different volumes of mud liquid can be contained each time. Record the mud ratio measured by each replacement cylinder 6, and then take the average value of all the mud ratios. For example, select three replacement cylinders 6 with gradually increasing major axis lengths. The data read by the data processor 42 are F1, F2, and F3 respectively. Then take the average value of the three data to ensure the credibility of the test data.
[0074] In some embodiments, referring to Figure 6 and Figure 7 , a leveling assembly 8 is provided at the bottom of the handheld housing 1. The leveling assembly 8 includes a first bracket 81, a second bracket 82, and a base 83. The first bracket 81 is provided at the bottom of the handheld housing 1; one end of the second bracket 82 is inserted into the first bracket 81; the base 83 is hinged to the other end of the second bracket 82. The base 83 contacts the plane, and the second bracket 82 supports the first bracket 81, thereby driving the handheld housing 1 to be supported, so that the handheld housing 1 is kept in a horizontal state, and further ensuring that the top opening of the material storage container 2 is in a horizontal state.
[0075] As an implementation manner of the insertion connection between the first bracket 81 and the second bracket 82, the first bracket 81 has a cross-shaped hinge hole 811. The cross-shaped hinge hole is divided into a horizontal hole arranged along the length direction of the handheld housing 1 and a vertical hole arranged along the thickness direction of the handheld housing 1. The horizontal hole and the vertical hole communicate with each other and are vertically crossed. The second bracket 82 is provided with a hinge head corresponding to the cross-shaped hinge hole 811. In the storage state, the hinge head extends into the horizontal hole, and in the support state, the hinge head extends into the vertical hole.
[0076] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
