DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0022] Embodiment one:
[0023] As Figures 1 to 5 shown, the present embodiment provides a solid-liquid density detector, which comprises a control display host 1 and a weighing assembly A and a weighing assembly B installed in a shell body 2. Specifically, the control display host 1 is electrically connected with a weighing sensor A 32 and a weighing sensor B 42. The weighing sensor A 32 is located in the weighing assembly A, and the weighing sensor B 42 is located in the weighing assembly B. The control display host 1 is a prior art, which is used to display the weighing reading of the weighing sensor A 32 and the weighing sensor B 42, and also has a zero setting function.
[0024] Weighing component A is installed on the bottom inner surface of the outer casing 2. Specifically, weighing component A includes a weighing sensor A32 and a load-bearing plate A33. The weighing sensor A32 is installed on the bottom of the load-bearing plate A33 and is installed on the bottom inner surface of the outer casing 2. A bracket 31 is installed on the weighing component A and the bracket 31 extends out of the equipment opening 21 on the upper end of the outer casing 2. Specifically, the bottom end of the bracket 31 is fixedly installed on the upper surface of the load-bearing plate A33. The top four corners of the bracket 31 have clamping grooves 311. A positioning screw 312 is threaded to one side wall of the clamping groove 311. The positioning screw 312 tightens the suspension rope 9 in the clamping groove 311 by rotating. By setting the clamping groove 311 and the positioning screw 312, the clamping of the suspension rope 9 can be easily achieved.
[0025] A glass container 41 is mounted on weighing component B, which is mounted on weighing component A and located inside bracket 31. Specifically, weighing component B includes a load cell B42 and a load-bearing plate B43. The load cell B42 is mounted on the bottom of the load-bearing plate B43 and on the upper surface of the load-bearing plate A33. The glass container 41 is mounted on the upper surface of the load-bearing plate B43. The load cell B42 is used to measure the weight of the object to be measured. By mounting weighing component B on weighing component A, the load cell A32 can measure the weight of weighing component B and its related equipment, as well as the weight of the object to be measured.
[0026] like Figure 2 and Figure 3 As shown, when testing the density of a solid, an appropriate amount of liquid water 411 is injected into the glass container 41. The liquid water 411 completely submerges the auxiliary basket 5. The upper end of the auxiliary basket 5 is equipped with a cover that can be opened and locked, so that the block to be tested 51 can be placed inside the auxiliary basket 5. The density of the auxiliary basket 5 is much greater than that of water. Under the gravity of the auxiliary basket 5, the block to be tested 51 is completely submerged in the liquid water 411. The upper end of the auxiliary basket 5 is suspended from the top of the bracket 31 by a rope 9, and the block to be tested 51 is placed inside the auxiliary basket 5. Solid density testing operation procedure: Preparation (install the matching auxiliary basket 5 on the calibrated instrument. The auxiliary basket 5 should not be in contact with the glass container 41. Add an appropriate amount of water to the glass container 41 to submerge the auxiliary basket 5 and the block to be tested 51) → Turn on the control and display host 1 and zero it → Place the block to be tested 51 into the auxiliary basket 5 and completely submerge it (if the density of the block to be tested 51 is less than that of water, to prevent it from floating, close the lid to ensure that the auxiliary basket 5 is submerged) → Output the results.
[0027] Principle: After the preparation work is completed and the control and display host 1 is powered on and zeroed, the weighing sensor will detect the added weight. The block to be tested 51 is gently placed into the auxiliary basket 5. After the block to be tested 51 is stationary and stable, according to the structural characteristics of this device, the reading detected by the weighing sensor B42 is the mass G1 of the block to be tested 51: G1 = F 浮 =v排 ρ 水 g = m 水 g, therefore mass m 水 =v 排 ρ 水 Where G1 is the mass of the block 51 to be tested, and F 浮 The test block 51 is subjected to the buoyancy of water, ρ 水 ρ is the volume of water displaced when the test block 51 is submerged in water, which is also equal to the volume of the test block 51. 水 Let g be the density of water and g be the acceleration due to gravity. Since the density of water is 1 g / cm³, when the volume unit of water is cubic centimeters and the mass unit is grams, the volume and mass values are consistent. This device uses grams as the mass unit. When the load cell B42 converts the weight it carries into mass, it measures the volume (v) of water in cubic centimeters. Simultaneously, the load cell A32 measures the net weight of the object being measured, G² = mg, which can be converted into the mass (m). In summary, the load cell B42 measures the volume (v) of the object in cubic centimeters, and the load cell A32 measures the mass (m) of the object in grams. The density of the solid being measured can be calculated using the density formula ρ = m / v.
[0028] like Figure 4 and Figure 5 As shown, when testing liquid density, an appropriate amount of the liquid to be tested 412 is poured into the glass container 41. The liquid to be tested 412 completely submerges the auxiliary block 6. The density of the auxiliary block 6 is high enough to ensure that the auxiliary block 6 can be completely submerged in the liquid to be tested 412. The upper end of the auxiliary block 6 is suspended from the top of the bracket 31 by the suspension rope 9. Liquid density testing operation procedure: Preparation: Install the matching auxiliary block 6 (the auxiliary block 6 is a custom block with a known volume v1) on the calibrated instrument. The auxiliary block 6 must not be in contact with the glass container 41, which is achieved by the suspension rope 9 → Power on the control and display host 1 and zero it → Pour the liquid to be tested 412 directly into the glass container 41 and submerge the auxiliary block 6 → Output the result.
[0029] Principle: After the device is prepared and zeroed, the weighing sensor will detect the added weight. The liquid to be tested, 412, is gently poured into the glass container 41 and allowed to settle. Based on the device's structural characteristics, the weighing sensor B42 will bear a weight G3 = net weight of the liquid to be tested 412 + buoyancy force exerted by the liquid to be tested 412 on the auxiliary block 6. The weighing sensor A32 will bear a weight G4 = net weight of the liquid to be tested 412. Therefore, G3 - G4 = buoyancy force F exerted by the liquid to be tested 412 on the auxiliary block 6. 浮1 ; From the formula force F 浮1 =v 排1 ρ 液1 g = m 液1 g; where v排1 For auxiliary block 6 discharge the volume of the liquid to be measured 412, also equal to the volume of auxiliary block 6, ρ 液1 For the density of the liquid to be measured 412, g is the acceleration of gravity, =m 液1 For the mass of the liquid to be measured 412; can be converted to m 液1 Value, auxiliary block 6 is the known volume v1; according to the density formula ρ 液1 = m 液1 / v1 can be obtained by measuring the liquid density results.
[0030] In this embodiment, by installing the glass container 41 on the weighing assembly B, the support 31 on the weighing assembly A, and the weighing assembly B on the weighing assembly A; with the help of the auxiliary basket 5 and water, the density of any shape solid can be measured conveniently; with the help of the auxiliary block 6, the density of liquid can be measured conveniently, efficiently and accurately.

[0032] Please refer to Figure 1 , Figure 2 and Figure 4 , on the basis of reserving all the technical features in the specific embodiment one, the support feet 7 are threadedly connected at the four corner positions of the outer bottom of the outer shell 2, and the bubble level 8 is installed on the inner bottom surface of the outer shell 2; by arranging the bubble level 8, the weighing accuracy is improved, and the density detection accuracy is indirectly improved.
[0033] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
