Description

Technical Field

[0001] The present application relates to the technical field of concrete detection, and in particular to a concrete moisture content detector. Background Art

[0002] Concrete is the most common construction material in civil engineering construction and plays a vital role in the construction of buildings. Before concrete is transported to the site by tankers and poured, checking the water content of the concrete is one of the important steps. If the water content is too low, the concrete will become sticky and its fluidity will decrease. Uneven vibration will cause more bubbles in the later formed structure. If the water content is too high, the setting time of the concrete will increase, and the coarse aggregate will be distributed under the structure due to the influence of gravity, resulting in reduced strength above the structure.

[0003] Therefore, it is necessary to test the moisture content of concrete, but the detection instrument panels currently on the market do not have corresponding protection measures for the detection probes. During the placement or movement process, the probe surface is not subjected to any protective treatment. When friction or collision occurs, the detection accuracy of the probe is easily damaged, which invisibly reduces the accuracy of the detection results. A Chinese patent (Announcement No.: CN215525797U) discloses a concrete sand and gravel moisture content detection device, which can protect the detection end of the detector. However, the above document does not facilitate cleaning the concrete contaminated on the detection end. Since the detection end of the detector needs to be inserted into the concrete pile during detection, the concrete is easily contaminated on the detection head. In order to avoid affecting the results of the secondary detection, the user is also required to carry wiping items such as paper towels for wiping. It is easy for the user to not carry wiping items, which makes it inconvenient to wipe the detection end. Utility Model Content

[0004] In response to the deficiencies in the prior art, the present application provides a concrete moisture content detector that has the advantages of being easy to clean, thus solving the problem of inconvenient cleaning.

[0005] To achieve the above objectives, the present application provides the following technical solutions: a concrete moisture content detector, comprising a detector body, a detection terminal mounted on the top of the detector body for measurement, a protective cylinder provided at the lower end of the detector body for protecting the detection terminal, limit assemblies provided at the upper and lower ends of the detector body for fixing the protective cylinder to the detector body, and a wiping assembly provided on the inner side of the protective cylinder for cleaning and wiping the detection terminal;

[0006] The wiping assembly includes a cylinder cover, a wiping block, two vertical plates installed on the top of the cylinder cover, clamping blocks installed on the left and right sides of the wiping block for plugging it into the vertical plates, an inserting block installed on the opposite sides of the two vertical plates, and a pulling block installed on the top of the cylinder cover.

[0007] By adopting the above technical solution, the contaminated concrete on the detection end can be wiped off without the user having to carry additional wiping items to prevent the user from not carrying the wiping items.

[0008] Furthermore, the protection tube is in the shape of a rectangle with its upper and lower ends missing, and both the left and right walls of the inner cavity of the protection tube are provided with sliding grooves for the insert to slide inside.

[0009] The above technical solution can prevent the vertical plate and the cylinder cover from falling off the protective cylinder.

[0010] Furthermore, a spring is fixed to the bottom of the inner side of the slide groove, and the other end of the spring is fixed to the bottom of the insert block.

[0011] The above technical solution can ensure that the cylinder cover can always abut against the protective cylinder.

[0012] Furthermore, a slot for the card block to be engaged is provided on one side opposite to the two vertical plates, and a through hole is provided on the top of the wiping block for the detection end to pass through the outside of the wiping block.

[0013] The adoption of the technical solution makes it easy to replace the wiping block.

[0014] Furthermore, the limiting assembly includes a frame plate, two limiting blocks, two pull rods, two torsion springs, a slide plate, a connecting block installed on the left and right inner walls of the slide plate, and an I-shaped rod installed on the left and right inner walls of the frame plate to prevent the connecting block from falling. The torsion spring is sleeved on the outside of the I-shaped rod, the limiting block is hingedly connected to the top end of the pull rod, the connecting block is hingedly connected to the end of the pull rod away from the limiting block, and the slide plate is slidably connected to the outside of the frame plate.

[0015] By adopting the above technical solution, the protective tube can be fixed to the upper end or the lower end of the detector body to prevent the protective tube from being lost.

[0016] Furthermore, a sliding block is fixed on the opposite side of the two limit blocks to prevent them from falling, and the front and rear walls of the frame plate cavity are provided with two sets of sliding grooves for the sliding blocks to slide inside.

[0017] The above technical solution can prevent the limiting block from falling off.

[0018] Furthermore, both left and right ends of the frame plate are provided with sliding holes for two connecting blocks to pass through.

[0019] The above technical solution is adopted to connect the slide plate with the connecting block.

[0020] Furthermore, two card slots for the limit blocks to be engaged are provided at both the left and right ends of the protective tube.

[0021] The above technical solution is adopted to fix the protective tube in the frame plate.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] The concrete moisture content detector is provided with a wiping component, which can wipe off the concrete contaminated on the detection end 2, without the user having to carry additional wiping items to prevent the user from not carrying the wiping items. By providing a limiting component, the protective tube can be fixed to the top or bottom of the detector, which can effectively prevent the protective tube from being lost.

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] See also Figure 1-2In this embodiment, a concrete moisture content detector includes a detector body 1, a detection end 2 installed on the top of the detector body 1 for measurement, a protective tube 4 for protecting the detection end 2 is provided at the lower end of the detector body 1, and limit assemblies for fixing the protective tube 4 on the detector body 1 are provided at the upper and lower ends of the detector body 1, and a wiping assembly for cleaning the detection end 2 is provided on the inner side of the protective tube 4.

[0034] See also Figure 3 The wiping assembly in this embodiment includes a cylinder cover 51, a wiping block 54, two vertical plates 52 installed on the top of the cylinder cover 51, clamping blocks 53 installed on the left and right sides of the wiping block 54 for plugging it into the vertical plates 52, inserting blocks 55 installed on the opposite sides of the two vertical plates 52, and a pulling block 56 installed on the top of the cylinder cover 51.

[0035] Among them, the protective tube 4 is a rectangle with missing upper and lower ends, and the left and right walls of the inner cavity of the protective tube 4 are provided with sliding grooves for the insert block 55 to slide inside it, so that when the vertical plate 52 slides in the protective tube 4, it can effectively prevent it from falling out of the protective tube 4, and can keep the two vertical plates 52 always connected to the protective tube 4.

[0036] In addition, a spring is fixed to the bottom of the inner side of the slide groove, and the other end of the spring is fixed to the bottom of the insert block 55. The spring can provide a certain resistance to the insert block 55. When the protective tube 4 is fixed to the lower end of the detector body 1, it can ensure that the two vertical plates 52 will not slide out of the protective tube 4, so that the tube cover 51 can always be in contact with the protective tube 4.

[0037] In addition, slots for the card blocks 53 to be engaged are provided on the opposite sides of the two vertical plates 52, so that the wiping block 54 can be installed on the two vertical plates 52, so that the two vertical plates 52 can drive the wiping block 54 to move in the protective tube 4 through the card blocks 53, and a through hole is provided on the top of the wiping block 54 for the detection end 2 to pass through the outside of the wiping block 54, so that the detection end 2 can pass through to the outside of the wiping block 54, so that the wiping block 54 can wipe the outside of the detection end 2.

[0038] See also Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The limiting assembly in this embodiment includes a frame plate 31, two limiting blocks 32, two pull rods 33, two torsion springs 36, a slide plate 37, a connecting block 34 installed on the left and right inner walls of the slide plate 37, and an I-shaped rod 35 installed on the left and right inner walls of the frame plate 31 to prevent the connecting block 34 from falling. The torsion spring 36 is sleeved on the outside of the I-shaped rod 35, the limiting block 32 is hingedly connected to the top end of the pull rod 33, the connecting block 34 is hingedly connected to the end of the pull rod 33 away from the limiting block 32, the slide plate 37 is slidably connected to the outside of the frame plate 31, and the slide plate 37 and the frame plate 31 are both hollow plates.

[0039] Secondly, sliding blocks are fixed on opposite sides of the two limit blocks 32 to prevent them from falling, and two sets of sliding grooves are opened on the front and rear walls of the inner cavity of the frame plate 31 for the sliding blocks to slide inside.

[0040] At the same time, two card slots for the limit blocks 32 to be engaged are provided at both ends of the left and right sides of the protective tube 4, so that the protective tube 4 can be fixed on the inner side of the frame plate 31, and since the internal structure position and orientation of the upper and lower limit components are the same, and the two limit components are respectively located at the upper and lower ends of the detector body 1, and one end of the protective tube 4 is abutted against the tube cover 51, the ports of the protective tube 4 fixed in the two limit components are consistent. However, when the protective tube 4 is fixed at the upper and lower ends respectively, the positions of the card slots moved into by the upper limit component and the lower limit component are different. Therefore, if the protective tube 4 is fixed at the lower end of the detector body 1, the two limit blocks 32 of the lower limit component are engaged with the two card slots at the top of the protective tube 4, and vice versa, the two limit blocks 32 of the upper limit component are engaged with the two card slots at the lower end of the protective tube 4.

[0041] In addition, sliding holes are provided at both ends of the frame plate 31 for the two connecting blocks 34 to pass through, so that the two connecting blocks 34 can be connected to the slide plate 37, so that the slide plate 37 can drive the two connecting blocks 34 to move, and a round hole is provided on the top of the connecting block 34 for the I-shaped rod 35 to pass through, so that the connecting block 34 can slide on the outside of the I-shaped rod 35.

[0042] The working principle of the above embodiment is:

[0043] When in use, when it is necessary to wipe the detection end 2 of the detector body 1 for secondary detection, by fixing the protective cylinder 4 on the top of the detector body 1, the detection end 2 can be inserted into the interior thereof through the through hole of the wiping block 54, and the user can pull the cylinder cover 51 upward through the pulling block 56, so that the inserting block 55 squeezes the spring, so that the cylinder cover 51 drives the wiping block 54 to move through the two vertical plates 52, so that the wiping block 54 can wipe off the concrete contaminated on the detection end 2, and the user does not need to carry additional wiping items such as paper towels, which can reduce the probability of forgetting to carry wiping items and avoid affecting the secondary detection of the detector body 1. If the wiping block 54 needs to be replaced, the protective cylinder 4 is removed from the detector body 1, and the above steps are repeated, so that the two vertical plates 52 can pull the wiping block 54 out of the protective cylinder 4, and the wiping block 54 can be removed from the two vertical plates. The plate 52 is pulled out so that a new wiping block 54 can be replaced; when the detection end 2 needs to be protected, the slide plate 37 is pulled downward, so that the slide plate 37 pulls the two pull rods 33 to move through the two connecting blocks 34, and at the same time the connecting block 34 squeezes the torsion spring 36, so that the two pull rods 33 can pull the two limit blocks 32 to move away from each other, so that the protective tube 4 can be sleeved on the outside of the detection end 2, and the slide plate 37 is released. Under the elastic force of the torsion spring 36, the two limit blocks 32 can be pushed to move relative to each other and move into the two card slots at the lower end of the protective tube 4, so that the protective tube 4 can be fixed in the upper end frame plate 31, so that the protective tube 4 can protect the detection end 2, and if the detector body 1 needs to be tested, the protective tube 4 is removed from the top of the detector body 1 and can be installed at the lower end of the detector body 1 to avoid the protection tube 4 being lost.
