Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a novel mud specific gravity testing device. Background Technology

[0002] Mud hydrometers are widely used on construction sites to measure the specific gravity of drilling mud for pile foundations, cement grout, etc. The traditional method for measuring the specific gravity of mud is to take a sample of mud and place it in a container on one side, move the rider until the scale is balanced, and then take a reading to obtain the specific gravity of the mud. The operation process of the traditional mud hydrometer is relatively cumbersome, requires certain operating skills from the operator, and can be cheated by adding stones or removing marbles, and the specific gravity of the mud is not intuitive. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a new type of mud specific gravity detection device. During the mud preparation stage, the float can be placed in the mud preparation container to obtain the mud specific gravity directly without sampling, and the operation is simple.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is a novel mud specific gravity detection device, comprising:

[0005] A container for holding mud, the container having an opening at the top;

[0006] A cylindrical pontoon for vertically floating on the mud has multiple scale lines arranged along the axial direction on the pontoon, and each scale line is marked with a mud specific gravity value that is inversely proportional to the height of the scale line. This allows the mud specific gravity to be determined by observing the mud specific gravity value corresponding to the scale line aligned with the mud surface when the pontoon is vertically floating in the mud.

[0007] A limiting collar is provided in the horizontal direction. One end of the limiting collar is detachably connected to the container. The limiting collar is adapted to the float. By fitting the limiting collar around the outer periphery of the float, the float remains vertical in the floating state.

[0008] A further improvement of this novel mud specific gravity testing device is that the certain inverse proportional relationship is: h = F_buoyancy / (ρ_mud gπr) 2 ), wherein h represents the height of the scale line, ρ mud represents the specific gravity of the mud, F buoyancy represents the weight of the buoy, g represents the acceleration due to gravity, π represents pi, and r represents the radius of the buoy.

[0009] A further improvement of this novel mud specific gravity detection device is that multiple balls are rolled around the inner circumference of the limiting collar, and when the limiting collar is fitted around the outer circumference of the float, the multiple balls are all in contact with the float.

[0010] A further improvement of this novel mud specific gravity testing device is that the number of limiting collars is two, and the two limiting collars are spaced apart along the axial direction of the float.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] The specific gravity of the mud can be directly determined by observing the draft of the buoy. It can be measured directly during the mud preparation stage without sampling, making the operation simple. Attached Figure Description

[0018] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0019] The novel mud specific gravity detection device of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figures 1-3 A new type of mud specific gravity testing device includes:

[0021] Container 1 for holding mud 6, the container 1 having an opening at the top;

[0022] The cylindrical float 2 is used to float vertically on the mud 6. Multiple scale lines 5 are arranged on the float 2 along the axial direction. Each scale line 5 is marked with a mud specific gravity value that is inversely proportional to the height of the scale line 5. This allows the mud specific gravity of the mud 6 to be obtained by observing the mud specific gravity value corresponding to the scale line 5 aligned with the surface of the mud 6 when the float 2 is floating vertically in the mud 6.

[0023] A limiting collar 3 is set in the horizontal direction. One end of the limiting collar 3 is detachably connected to the container 1. The limiting collar 3 is adapted to the float 2. By fitting the limiting collar 3 around the outer periphery of the float 2, the float 2 remains vertical in the floating state.

[0024] Specifically, a connecting rod 4 is connected to the outer side of the limiting collar 3, and a buckle for engaging with the mouth of the container 1 is connected to the end of the connecting rod 4 that is relatively away from the limiting collar 3.

[0025] like Figure 3 As shown, the float 2 can be placed directly in the mud pool, and a person can hold the connecting rod 4 to keep the limiting collar 3 horizontal, thereby ensuring that the float 2 remains vertical, so as to directly detect the specific gravity of the mud in the mud pool without taking samples to the container 1, thus improving the detection efficiency.

[0026] Preferably, this inverse relationship is: h = F_buoyancy / (ρ_mud gπr) 2 ), where h represents the height of the scale line 5, ρ represents the specific gravity of the mud, F represents the weight of the buoy, g represents the gravitational acceleration, π represents pi, and r represents the radius of the buoy.

[0027] Based on Archimedes' principle: F_buoyancy = ρ_mud gV_displaced; V_displaced = πr 2 *h; This yields h = F_buoyancy / (ρ_mud gπr) 2 In this equation, F_buoyancy, g, π, and r are constants, while h and ρ_mud are variables. That is, given a fixed mass and radius of the buoy 2, the draft (i.e., the height at which the scale line 5 is set) is inversely proportional to the mud specific gravity. Based on this principle, it is relatively easy to obtain the draft corresponding to different mud specific gravities. Thus, the draft at the corresponding specific gravity is marked to form the scale line 5, and then the scale line 5 is used to detect the mud specific gravity.

[0028] Specifically, before testing, the container 1 and the float 2 should be kept clean and free of impurities, and the contact between the collar and the float 2 should be smooth and even.

[0029] Preferably, the inner circumference of the limiting collar 3 is connected with a plurality of balls, and when the limiting collar 3 is fitted onto the outer circumference of the float 2, the plurality of balls are all in contact with the float 2.

[0030] By setting multiple of these ball bearings, the vertical floating stability of the float 2 is ensured, preventing it from tipping over and affecting the detection results.

[0031] Preferably, there are two limiting collars 3, and the two limiting collars 3 are spaced apart along the axial direction of the float 2.

[0032] By setting two limiting collars 3, the floating stability of the pontoon 2 is improved, and tilting is avoided.
