Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering detection equipment, in particular to a concrete water content detection device. Background Art

[0002] Concrete is one of the most commonly used materials in construction projects. Its strength, durability and other properties are closely related to the moisture content in concrete. Therefore, accurate and reliable detection of the moisture content in concrete is crucial to ensure the quality and safety of construction projects. The moisture content in concrete not only affects the strength and durability of concrete, but is also directly related to the construction performance and later maintenance of concrete. In actual operation, the weighing method is usually the simplest to detect the moisture content of concrete, that is, to measure the moisture content of concrete by weighing. The specific method is to first sample the concrete, dry it at a specific temperature (such as 105°C) until the mass remains unchanged, and then measure its mass change to calculate the moisture content in the concrete. However, in the prior art, the water in the concrete is mixed with the concrete. During the drying process, the water in the concrete is difficult to heat quickly and the evaporation rate is extremely slow, which makes the detection process time-consuming and labor-intensive, affecting the efficiency of concrete moisture content detection.

[0046] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the specification of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0047] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0048] Example: See Figure 1-Figure 6 The utility model provides a concrete moisture content detection device. In practical application, in order to improve the detection efficiency when used for concrete moisture content detection, the device comprises an outer box body 1, a box cover 2 connected to the outer box body 1, a vibration mechanism 3, a weighing mechanism 4 and an evaporation component 5 arranged in the outer box body 1.

[0049] Specifically, the outer box body 1 is a square box body with an open top. The outer box body 1 is used to protect the internal structure and extend the service life of the equipment. The outer box body 1 is also provided with a plurality of slide grooves 11. Preferably, the number of the slide grooves 11 is four, and the four slide grooves 11 are located at the four corners of the bottom end of the outer box body 1. The outer box body 1 is movably connected to the vibration mechanism 3 to increase the stability of the vibration mechanism 3 during vibration.

[0050] The interior of the box cover 2 is a cavity, and the box cover 2 is arranged at the top opening of the outer box body 1. The box cover 2 is adapted to the outer box body 1 so that the box cover 2 can fit more closely to the edge of the outer box body 1 when closed on the outer box body 1, reducing the gap generated when the box cover 2 is buckled with the outer box body 1, thereby improving the sealing between the two. The box cover 2 is provided with an air intake 21 on one side close to the outer box body 1, and a plurality of exhaust holes 22 are provided on the top of the box cover 2. The water vapor after baking enters the box cover 2 through the air intake 21 and is then discharged through the exhaust holes 22.

[0051] like Figure 2-Figure 6 As shown, in this embodiment, the vibration mechanism 3 is arranged in the outer box body 1, and the vibration mechanism 3 is movably connected to the plurality of chutes 11, that is, the vibration mechanism 3 can vibrate along the paths of the four chutes 11, and the vibration mechanism 3 can vibrate the concrete test block to make the coarse aggregate and silt and other materials in the concrete test block sink, thereby accelerating the analysis of water in the concrete.

[0052] The vibration mechanism 3 includes an inner box 31, a gear ring 32 and an elastic component 35 connected to the inner box 31, a rotating ring 33 connected to the gear ring 32, and a motor 34 connected to the rotating ring 33. The inner box 31 is arranged in the outer box 1, and a sliding support adapted to the slide groove 11 is fixedly arranged at the bottom end of the inner box 31, and the inner box 31 slides on the slide groove 11 through the sliding support. The gear ring 32 is arranged on one side of the inner box 31, and the gear ring 32 is fixedly connected to the inner box 31, wherein a plurality of tooth grooves are arranged circumferentially on the gear ring 32, and the tooth grooves on the gear ring 32 are all right-angled trapezoidal grooves. The rotating ring 33 is arranged on one side of the gear ring 32, and the rotating ring 33 is adapted to the gear ring 32, and a plurality of trapezoidal teeth adapted to the trapezoidal grooves are arranged on the side of the rotating ring 33 close to the gear ring 32. The motor 34 is fixedly arranged at one side of the outer box 1, and the output shaft of the motor 34 rotates through the outer box 1 and extends into the outer box 1. The rotating ring 33 is fixedly arranged at the end of the output shaft of the motor 34, and the motor 34 can drive the rotating ring 33 to rotate rapidly. The elastic component 35 is arranged on a side of the inner box 31 away from the gear ring 32, and the two ends of the elastic component 35 are fixedly connected to the inner box 31 and the outer box 1 respectively, so that the inner box 31 is reset by the elastic force of the elastic component 35 after moving. In this embodiment, when the motor 34 drives the rotating ring 33 to rotate, the trapezoidal teeth slide out of the tooth grooves. Since the trapezoidal teeth abut against the protrusions of the two adjacent tooth grooves on the tooth ring 32, the trapezoidal teeth can push the tooth ring 32 to move, thereby driving the inner box body 31 to move within the path of the slide groove 11, and the inner box body is quickly reset under the action of the elastic component 35, so that the inner box body 31 can move back and forth along the path of the slide groove 11, that is, the purpose of rapid vibration.

[0053] like Figure 4-Figure 6 As shown, in this embodiment, the weighing mechanism 4 is disposed in the vibration mechanism 3, and the weighing mechanism 4 is movably connected to the vibration mechanism 3, and the weighing mechanism 4 is used to weigh the concrete test block before and after drying.

[0054] The weighing mechanism 4 includes a carrying box 41, a gravity sensor 42 and a display 43. The carrying box 41 is arranged in the inner box 31 and is movably connected to the inner box 31. The carrying box 41 is used to hold concrete test blocks, that is, the carrying box 41 can slide up and down in the inner box 31. The gravity sensor 42 is arranged at the bottom end of the carrying box 41, and the gravity sensor 42 is fixedly connected to the inner box 31. The gravity sensor 42 is used to measure the weight of the concrete test block placed in the carrying box 41. It is a prior art and will not be described in detail here. The display 43 is arranged on the outer box 1, and the gravity sensor 42 is electrically connected to the display 43 to display the value measured by the gravity sensor 42.

[0055] In this embodiment, the evaporation component 5 is fixedly disposed in the box cover 2. When the box cover 2 and the outer box body 1 are closed, the evaporation component 5 can bake the moisture in the concrete at high temperature to evaporate and discharge the moisture.

[0056] The evaporation component 5 includes a first heater 51 connected to the box cover 2, a suction fan 52 and a first power supply 53. The first heater 51 is arranged at the bottom of the box cover 2 and is fixedly connected to the box cover 2. When the box cover 2 and the outer box body 1 are closed, the first heater 51 is located directly above the concrete test block, and the concrete test block in the carrier box 41 is baked by the first heater 51. Preferably, the first heater 51 is a vortex heating tube. The heating tube with a vortex structure can increase the heating area, so that the water precipitated in the concrete is heated more fully and the evaporation rate is accelerated. The suction fan 52 is arranged in the box cover 2, wherein the suction fan 52 is an exhaust fan to extract water vapor into the external environment. The first power supply 53 is arranged at the top of the box cover 2, and the first power supply 53 is electrically connected to the first heater 51 and the suction fan 52 respectively. The first power supply 53 is used to supply power to the first heater 51 and the suction fan 52 separately to prevent the first heater 51 and the suction fan 52 from stopping working due to power reasons.

[0057] In this embodiment, a concrete test block is placed in the weighing mechanism 4. At this time, the weight of the concrete test block is recorded for the first time, and then the box cover 2 and the outer box body 1 are closed. Under the action of the vibration mechanism 3, the water in the concrete test block is quickly precipitated, and the precipitated water is quickly dried by the evaporation component 5, and the water vapor is discharged. When the weight of the concrete test block in the weighing mechanism 4 no longer changes, it means that the water in the concrete has been completely evaporated and discharged. At this time, the weight of the concrete test block is recorded again, and the water content in the concrete test block can be obtained by the difference between the two recorded concrete weights. That is, the disadvantage of the slow evaporation rate of the water in the concrete test block by baking in the prior art is effectively solved, and the technical effect of quickly drying the water in the concrete and improving the efficiency of concrete water content detection is achieved.

[0058] In some preferred embodiments, in order to improve the weighing accuracy of the concrete test block, the weighing mechanism 4 also includes two groups of slide rails 44, and the two groups of slide rails 44 are symmetrically arranged on both sides of the inner wall of the inner box 31, and are fixedly connected to the inner box 31, wherein each two slide rails 44 form a group, and each slide rail 44 is also slidably provided with a slider, and the slider is fixedly connected to the supporting box 41, thereby reducing the friction between the supporting box 41 and the inner box 31 when sliding, preventing the friction between the two from having a significant impact on the weighing result of the concrete test block, and improving the accuracy of the numerical value measured by the gravity sensor 42.

[0059] In this embodiment, the elastic component 35 includes a return spring 351 and a telescopic sleeve 352. The return spring 351 is arranged on a side of the inner box 31 away from the gear ring 32. One end of the return spring 351 is fixedly connected to the outer box 1, and the other end is fixedly connected to the inner box 31. The inner box 31 is reset after moving by the elastic force of the return spring 351. The telescopic sleeve 352 is sleeved outside the return spring 351. The telescopic sleeve 352 is adapted to the return spring 351, that is, the internal size of the telescopic sleeve 352 matches the size of the return spring 351, so as to prevent the return spring 351 from being twisted and deformed, thereby losing its elasticity.

[0060] In some preferred embodiments, in order to further accelerate the evaporation of water in the concrete, the carrier box 41 is further provided with a second heater 411, which is arranged in the box wall of the carrier box 41 and is a spiral heating pipeline, so that the second heater 411 evenly heats the inner wall of the carrier box. A second power supply 412 is further provided in the inner box 31, and the second heater 411 is electrically connected to the second power supply 412, and the second power supply 412 is used to supply power to the second heater 411.

[0061] In some preferred embodiments, in order to facilitate the staff to take the box cover 2, two handles 23 are further provided on the box cover 2. The two handles 23 are symmetrically arranged on both sides of the box cover 2 and are fixedly connected to the box cover 2. When the box cover 2 needs to be taken, the box cover 2 can be moved by the handles 23, which is more convenient.
