[0027] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] As Figures 1 - 3 shown, a concrete strength detection device for a water conservancy project includes a main machine 1 and a detection component 2. The detection component 2 is connected to the main machine 1 based on radio data. It is characterized in that it further includes cabin boxes 3 that are symmetrically arranged and connected into one body through a rod body 4. A vertical rod 5 is hinged on the mounting rod 37 of the cabin box 3;

[0029] The two vertical rods 5 deflect towards each other and can be switched from a state perpendicular to the rod body 4 to a parallel state;

[0030] A limiting sleeve 52 is slidably arranged on the vertical rod 5, and a resistance spring 53 is arranged on the vertical rod 5. In the default state of the resistance spring 53, the limiting sleeve 52 is distributed at the connection where the vertical rod 5 and the mounting rod 37 are coaxial;

[0031] Rectangular strip grooves 51 are formed on the adjacent sides of the two vertical rods 5, and an insertion sleeve 6 with a port facing the rectangular strip groove 51 and located on the vertically driven sliding of the vertical rod 5 is further included;

[0032] The two detection components 2 are respectively inserted into the insertion sleeve 6, and the detection surfaces are adjacent to each other.

[0033] Specifically, the main machine 1 and the detection component 2 in the embodiment are Q62 concrete strength detectors, which are existing products, so the specific principle will not be described in detail. For the convenience of measuring the dam body, the data transmission of the main machine 1 and the detection component 2 in the embodiment can be connected by wire or wirelessly, such as well-known wireless connection methods such as radio.

[0034] Secondly, when in use, the relationship between the vertical rod 5 and the cabin box 3 is alsoFigure 1 The state shown, that is, the vertical rod 5 is perpendicular to the rod body 4. The detection component 2 is fixed in advance through the insertion sleeve 6, and the detection surfaces of the two detection components 2 face the dam body. The rod body 4 is spanned across the dam body, and then the vertical rod 5 is extended to the side wall of the dam body. By driving the insertion sleeve 6 to move downward, the detection requirements for the concrete hardness at multiple points on the dam body are realized.

[0035] In the above technology, by inserting the two detection components 2 into the insertion sleeves 6 on the vertical rod 5 respectively and driving the insertion sleeve 6 to move downward, the detection requirements for multiple points at the height of the dam body are met.

[0036] Secondly, the vertical rod 5 in the embodiment is hinged to the mounting rod 37 of the cabin box 3. Through the limit sleeve 52, the vertical rod 5 can be switched between a state perpendicular to the rod body 4 and a parallel state for easy use and storage.

[0037] As a further embodiment provided by the present utility model, a slide rail member 70 is arranged inside the vertical rod 5, and the insertion sleeve 6 is slidably arranged on the slide rail member 70;

[0038] At both ends of the slide rail member 70 extending into the cabin box 3, guide rollers 71 are rotatably arranged. A steel cable 72 is sleeved between the two guide rollers 71, and the insertion sleeve 6 is fixedly connected to the steel cable 72.

[0039] As a further embodiment provided by the present utility model, the slide rail member 70 is horizontally movable inside the vertical rod 5 and is centrally arranged inside the vertical rod 5 through an equidistant spring group 8 arranged on the inner wall of the vertical rod 5.

[0040] Furthermore, a rotating handle 31 is movably arranged on the cabin box 3. A transmission gear 32 is arranged on the shaft rod of the rotating handle 31, and a driven gear 33 meshing with the transmission gear 32 is arranged on the shaft rod of the guide roller 71 located inside the cabin box 3;

[0041] A retaining disc 331 is arranged on the driven gear 33. A plurality of balls arranged in a circumferential array are arranged on the side surface of the retaining disc 331 in contact with the transmission gear 32. The retaining disc 331 and the transmission gear 32 are in a blocking and disassembling fit, so that the slide rail member 70 moves horizontally along with the rotating handle 31.

[0042] Specifically, taking Figure 2 the shown position as a reference, push the rotating handle 31 to the left. Thus, under the blocking and disassembling of the retaining disc 331 and the transmission gear 32, the slide rail member 70 is inclined, so that the detection surface of the detection component 2 is away from the wall surface of the dam body. Then rotate to drive the steel cable 72 to move. At this time, the detection component 2 moves to a predetermined position following the insertion sleeve 6. At this time, the pushing force on the rotating handle 31 is withdrawn. Under the action of the equidistant spring group 8, the slide rail member 70 resets to the central state, and then the detection surface of the detection component 2 fits the wall surface of the dam body.

[0043] As a further embodiment provided by the present utility model, a flywheel 34 is arranged on the shaft rod of the rotating handle 31, and the flywheel 34 is in detection cooperation with a Hall sensor arranged in the cabin box 3;

[0044] A display is arranged on the rotating handle 31, and the display is data-connected to the Hall sensor.

[0045] Specifically, in the embodiment, the Hall sensor is used to detect the flywheel 34 so as to obtain the downward movement height of the plug sleeve 6, thereby facilitating the height adjustment of the two plug sleeves 6 to keep them consistent.

[0046] It should be noted that the above-mentioned electronic components and control programs in the embodiments belong to the common general knowledge of those skilled in the art, so no detailed description will be given.

[0047] As a further embodiment provided by the present utility model, a conical rubber sleeve 61 is arranged on the inner wall of the plug sleeve 6, and the wide mouths of the two conical rubber sleeves 61 are arranged adjacent to each other.

[0048] Specifically, for the conical rubber sleeve 61 adopted in the embodiment, after the detection component 2 is inserted, the conical rubber sleeve 61 will deform to ensure the fixing effect on the detection component 2.

[0049] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
