Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a device for testing the humidity of concrete walls. Background Technology

[0002] Concrete: refers to a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as a cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] After concrete is poured and dried, mortar and other materials need to be applied to the concrete surface to level it. However, the drying time of concrete is relatively long, so it is necessary to test the internal humidity of the concrete to determine the dryness of the concrete and facilitate subsequent construction. Current equipment is not very accurate in detecting the humidity of concrete because it is in contact with the environment. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings by proposing a concrete wall humidity testing device: after the micro fan is started, it draws gas from inside the testing chamber through a cylindrical filter. The gas enters the testing chamber from the bonding ring and the concrete. After the humidity sensor is activated, it detects the humidity inside the testing chamber to determine the dryness of the concrete, facilitating subsequent output and improving the accuracy of the test.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A humidity testing device for concrete walls includes a detection cover. A fitting ring is welded to the outer wall of one end of the detection cover, and a detection structure is installed on the top outer wall and the inner wall of the detection cover.

[0008] Preferably, both the other ends of the first connecting seat and the second connecting seat are hinged with telescopic rods, and the bottom outer wall of the telescopic rod at the bottom of the first connecting seat is welded with a plug-in protrusion.

[0009] Preferably, the input end of the micro fan is connected to a pipe, and the other end of the pipe is connected to one end of the cylindrical filter screen.

[0010] Preferably, a bonding groove is provided at the center of one side of the outer wall of the bonding ring, and a silicone frame is bonded in the bonding groove.

[0011] Preferably, the miniature fan and humidity sensor are connected to the controller via wires, and the controller is connected to the battery via wires.

[0012] After the miniature fan starts, it draws gas from inside the detection hood through a cylindrical filter. The gas enters the detection hood from the bonding ring and the concrete. After the humidity sensor starts, it detects the humidity inside the detection hood to determine the dryness of the concrete, which facilitates subsequent output and improves the accuracy of the detection.

[0013] The beneficial effects of this utility model are as follows:

[0014] After the miniature fan starts, it draws gas from inside the detection hood through a cylindrical filter. The gas enters the detection hood from the bonding ring and the concrete.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0020] Reference Figure 1-3A concrete wall humidity testing device includes a detection cover 1. A fitting ring 2 is welded to the outer wall of one end of the detection cover 1. A detection structure 3 is installed on the top outer wall and the inner wall of the detection cover 1. A connecting seat 4 is installed at the center of one side outer wall of the detection cover 1, and a connecting seat 5 is installed at the center of the bottom outer wall of the detection cover 1. The detection structure 3 includes a humidity sensor 11 installed at the center of one side of the inner wall of the detection cover 1, a miniature fan 12 installed on the top outer wall of the detection cover 1, a cylindrical filter 13 installed on the top inner wall of the detection cover 1, and a battery 14 installed on the top outer wall of the detection cover 1. Gas enters the interior of the detection cover 1 from the fitting ring 2 and the concrete. After the humidity sensor 11 is activated, it detects the humidity inside the detection cover 1 to determine the dryness of the concrete, which facilitates subsequent output and improves the accuracy of the test.

[0021] Extend the telescopic rod 3 on the connecting seat 1 and the connecting seat 2. The telescopic rod 3 will attach the detection cover 1 together with the detection cover 1 to the concrete surface, which is convenient for detection on the concrete surface at different heights.

[0022] An observation opening is provided on the outer wall of one end of the detection cover 1, and an observation window 8 is installed at the observation opening of the detection cover 1. The observation window 8 has an "L" shaped cross-section, and personnel can observe the internal condition of the detection cover 1 through the observation window 8, which is convenient for use.

[0023] Both the other ends of the connecting seat 1 4 and the connecting seat 2 5 are hinged with telescopic rods 6, and the bottom outer wall of the telescopic rod 6 at the bottom of the connecting seat 1 4 is welded with a plug-in protrusion 7. The inclined structure of the connecting seat 1 4, the telescopic rod 6 and the plug-in protrusion 7 adheres the detection cover 1 to the surface of the concrete. The telescopic rod 6 presses the silicone frame 10 on the fitting ring 2, so that the detection cover 1 adheres to the outer wall of the concrete, reducing gas leakage.

[0024] The input end of the miniature fan 12 is connected to a pipe, and the other end of the pipe is connected to one end of the cylindrical filter 13. After the miniature fan 12 is started, it draws the gas inside the detection hood 1 through the cylindrical filter 13.

[0025] A bonding groove 9 is provided at the center of one side of the outer wall of the bonding ring 2, and a silicone frame 10 is bonded in the bonding groove 9.

[0026] The miniature fan 12 and the humidity sensor 11 are connected to the controller via wires, and the controller is connected to the battery 14 via wires.

[0027] Working principle: In use, the telescopic rods 3 on connecting seat 1 and connecting seat 2 are extended, and the telescopic rods 3 attach the detection cover 1 to the concrete surface, facilitating detection on concrete surfaces at different heights and making it easy to use. The insertion protrusion 7 at the bottom of the telescopic rod 6 on connecting seat 1 contacts the ground. The inclined structure of connecting seat 1, telescopic rod 6, and insertion protrusion 7 attaches the detection cover 1 to the concrete surface. The telescopic rod 6 presses against the silicone frame 10 on the bonding ring 2, making the detection cover 1 fit against the outer wall of the concrete, reducing gas leakage. After the micro fan 12 is started, it draws the gas inside the detection cover 1 through the cylindrical filter 13. The gas enters the inside of the detection cover 1 from the bonding ring 2 and the concrete. After the humidity sensor 11 is started, it detects the humidity inside the detection cover 1 to determine the dryness of the concrete, which facilitates subsequent output and improves the accuracy of detection. Personnel can observe the internal condition of the detection cover 1 through the observation window 8 of the detection cover 1 for easy use.
