Detailed implementation manners

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model will be further described below with reference to the embodiments.

[0022] Embodiment: Refer to Figures 1 to 3 , an automatic pressure-applying concrete penetrometer for building material detection, comprising a box body 1, a plurality of bases 2 are fixedly installed at the top of the box body 1, and a water outlet hole 21 is opened at the center of the base 2. The top of each of the plurality of bases 2 is connected with a female mold 3 through a fixing component. The fixing component includes arc plates 4 fixedly installed in a circular array at the bottom of the female mold 3. Arc grooves 41 are opened at the top of the base 2 and at corresponding positions with respect to the arc plates 4. The arc plates 4 are rotationally clamped with the arc grooves 41. The bottom of the arc plate 4 is fixedly installed with a U-shaped plate 42, and the outer wall of the U-shaped plate 42 is in contact with the inner wall of the arc groove 41. Connecting rods 43 are fixedly installed at both top ends of the U-shaped plate 42. Clamping grooves 44 are opened inside the base 2 and at corresponding positions with respect to the connecting rods 43. The connecting rods 43 are clamped with the clamping grooves 44. During detection, first, the concrete blocks to be detected are placed inside each female mold 3, and then the staff inserts the arc plates 4 at the bottom of the female mold 3 into the arc grooves 41 at the corresponding positions at the top of the base 2 until the arc plates 4 move to the bottom of the arc grooves 41. Then, the female mold 3 is rotated clockwise to drive the arc plates 4 at the bottom to rotate, so that the arc plates 4 are clamped, and the two connecting rods 43 at the top ends of the U-shaped plate 42 are clamped with the clamping grooves 44 at the corresponding positions, thereby being able to fix the female mold 3 again. The whole fixing process is convenient and fast, improving the detection efficiency.

[0023] The inner bottom wall of the box body 1 is fixedly installed with a water pump 5. The water outlet end of the water pump 5 is communicated with a connecting pipe 51, and the top end of the connecting pipe 51 is communicated with a plurality of flexible hoses 52 through a multi-way pipe. The other ends of the plurality of flexible hoses 52 all penetrate through the top of the box body 1 and are communicated with each water outlet hole 21. By turning on the water pump 5, the water inside the box body 1 can be pumped out and the concrete inside each female mold 3 can be subjected to penetration detection through the plurality of flexible hoses 52.

[0024] The outer wall of the box body 1 is communicated with a water inlet pipe 6, and the bottom end of the box body 1 is communicated with a water outlet pipe 61. Solenoid valves 62 are arranged on the outer sides of both the water inlet pipe 6 and the water outlet pipe 61. When water needs to be added, the solenoid valve 62 on the outer side of the water outlet pipe 61 is opened to complete the water addition. When the detection is completed or when it is not in use, the solenoid valve 62 on the outer side of the water outlet pipe 61 is opened to complete the drainage.

[0025] Two limiting grooves 7 are symmetrically formed in the inner wall of the box body 1. A floating plate 71 is slidably connected in the two limiting grooves 7 in a limiting manner. Sensors 72 are arranged on both the top wall and the bottom wall of one of the limiting grooves 7. Both of the two sensors 72 are electrically connected to the solenoid valve 62 on the outer side of the water inlet pipe 6. During the detection process, the floating plate 71 moves simultaneously with the change of the water level inside the box body 1 under the influence of buoyancy. When the floating plate 71 contacts the lower sensor 72 with the change of the water level, the solenoid valve 62 on the outer side of the water inlet pipe 6 is controlled to open to inject water into the box body 1. On the contrary, when the floating plate 71 contacts the upper sensor 72 due to the change of the water level, the solenoid valve 62 on the outer side of the water inlet pipe 6 is controlled to close, and at this time, the water injection stops, preventing the phenomenon of running out of water or overfilling with water, and improving the use effect of the device.

[0026] An annular groove 8 is formed in the top of the base 2, and a sealing ring 81 is placed inside the annular groove 8, which plays a sealing role and prevents water from flowing out through the gap between the base 2 and the female mold 3 during the detection process, improving the use effect of the device.

[0027] Two handles 31 are symmetrically and fixedly installed on the outer wall of the female mold 3. The length of the arc-shaped groove 41 is greater than the length of the arc-shaped plate 4, and the length of the arc-shaped groove 41 is at least twice the length of the arc-shaped plate 4, which is convenient for the staff to rotate the female mold 3 and facilitates its installation.

[0028] The working principle of the present utility model is as follows: During detection, first place the concrete block to be detected inside each female mold 3. Then, the staff inserts the arc-shaped plates 4 at the bottom of the female mold 3 into the arc-shaped grooves 41 at the corresponding positions on the top of the base 2 until the arc-shaped plates 4 move to the bottom of the arc-shaped grooves 41. Then, rotate the female mold 3 clockwise to drive the arc-shaped plates 4 at the bottom to rotate, so that the arc-shaped plates 4 are clamped, and the two connecting rods 43 at the top of the U-shaped plate 42 are clamped with the corresponding slots 44, thereby being able to fix the female mold 3 again. The entire fixing process is convenient and fast, improving the detection efficiency. Then, start the water pump 5 to pump out the water inside the box body 1 and conduct penetration detection on the concrete inside each female mold 3 through multiple hoses 52. During the detection process, the floating plate 71 moves simultaneously with the change of the water level inside the box body 1 under the influence of buoyancy. When the floating plate 71 contacts the lower sensor 72 with the change of the water level, control the solenoid valve 62 outside the water inlet pipe 6 to open and inject water into the box body 1. On the contrary, when the floating plate 71 contacts the upper sensor 72 due to the change of the water level, control the solenoid valve 62 outside the water inlet pipe 6 to close, and stop injecting water at this time to prevent the phenomenon of running out of water or adding too much water, improving the use effect of the device.

[0029] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
