DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0033] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0034] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0035] like Figure 1-10 The present invention provides an operating method of a concrete durability testing device, comprising the following steps:

[0036] S1. First, the coating material is stored in the storage sleeve 42 of the device for uniform coating of the impermeable test piece. The top button 31 is squeezed to drive the telescopic inner rod 32 to stretch up and down to squeeze the stored coating material. The coating material seeps out to the outer surface of the storage sleeve 42 along with the adjustment of the rotating cavity 38. Then, the rotating handle 35 is rotated to drive the storage sleeve 42 to rotate close to the inner side of the impermeable test mold. During the coating operation, the limiting plate 3 is fixed to the side of the impermeable test mold. Then, the top button 31 is squeezed to make the coating material seep out to the outer surface of the storage sleeve 42. Finally, the rotating handle 35 is rotated to make it rotate along the side of the impermeable test mold for one circle to complete the uniform coating operation.

[0037] S2, placing the test block into the anti-seepage test mold; then placing the anti-seepage test mold on the durability testing device to start the concrete durability anti-seepage test;

[0038] S3, attach the sensor 48 to the anti-seepage test mold, and send the test block humidity to the mobile phone in real time through the network. When 3 (primary anti-seepage) or 6 (secondary anti-seepage) of the 6 test blocks reach the humidity setting value, the mobile phone will ring and vibrate immediately to remind the staff to record the test data and remotely operate the switch 52 through the mobile phone 43 to turn off the durability detection device;

[0039] S4. When demoulding is required, the operator holds the rubber sleeve 144 on the impermeability test mold and pushes the hand wheel 141 on the impermeability test mold to rotate. The hand wheel 141 drives the rotating part 12 to rotate. The test block is separated from the inner wall of the cylinder under the action of the torsional force. At this time, the rotating part 12 is moved upward to separate it from the fixed part 11, thereby exposing the test block, which is convenient for the operator to quickly take out the test block; the whole process will not generate impact force on the test block, thereby greatly reducing the possibility of the test block being broken;

[0040] S5. Place the anti-seepage test mold with the exposed test block into the anti-seepage inverted demoulding device. The fixing part 11 is placed on the fixing support plate 25 of the anti-seepage inverted demoulding device. The mold fixing clamp 23 is fixed on the connecting column 24 of the anti-seepage inverted demoulding device through a clamping sleeve. The height and angle of the mold fixing clamp 23 can be adjusted by loosening and tightening the clamping sleeve so that the mold fixing clamp 23 supports the upper end of the fixing part 11. Finally, push the lower support plate 27 to drive the demoulding top block 26 to support the lower end of the test block and push the test block out of the fixing part 11, thereby completing the demoulding of the test block.

After moving to a suitable position, the electric push rod 3 is started, and the electric push rod 3 is lifted upward with the protective frame 2 to move upward. When the electric push rod 3 lifts the protective frame 2 to a suitable position, it can stop. Outdoors, the protective frame 2 will protect the body 1 to prevent direct sunlight from shining on the body 1. When it rains, the rain will directly fall on the top of the body, and the rain falling on the top of the body will flow into the drainage trough 4, which is set on both sides of the top of the protective frame 2; when the staff takes a break during work, the sunshade net 6 is put down to shade one side of the body 1 to prevent the sun from shining on the body when the sun's irradiation position changes, thereby realizing that the durability detection device can be used outdoors and can achieve the functions of rain and sun protection. The sunshade net 6 is set at both ends of the protective frame 2. When the sunshade net 6 is not in use, the sunshade net 6 is in a rolled-up state; when the sunshade net needs to be used, the sunshade net 6 is put down.

6. The concrete durability testing device according to claim 1, characterized in that: The durability detection device is provided with a mobile phone monitoring alarm, which includes a mobile phone monitoring alarm system, a sensor control system (50), a main control board (51), and a power switch (52); the mobile phone monitoring alarm system establishes a wireless communication connection with the sensor control system (50) through the MQTT protocol; the power switch (52) is connected to the durability test device, and the power switch is connected to the sensor control system (50).

7. A concrete durability test device and an operating method, based on the concrete durability test device according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1. First, the coating material is stored in the storage sleeve (42) of the device for uniformly coating the impermeable test piece. The top button (31) is pressed to drive the telescopic inner rod (32) to extend and retract up and down to squeeze the coating material in the storage sleeve (42). The coating material oozes out to the outer surface of the storage sleeve (42) as the rotating cavity (38) is adjusted. Then, the rotating handle (35) is turned to rotate the storage sleeve (42) closely against the inner side of the impermeable test mold; S2, placing the test block into the anti-seepage test mold; then placing the anti-seepage test mold on the durability testing device to start the concrete durability anti-seepage test; S3, attaching the sensor (48) to the anti-seepage test mold, and sending the humidity of the test block to the mobile phone in real time through the network; S4. When demoulding is required, the operator holds the rubber sleeve (144) on the impermeable test mold and pushes the hand wheel (141) on the impermeable test mold to rotate. The hand wheel (141) drives the rotating part (12) to rotate. The test block is separated from the inner wall of the cylinder under the action of the torsional force. At this time, the rotating part (12) is moved upward to separate it from the fixed part (11); S5. Place the impermeable test mold with the exposed test block into the impermeable inverted demoulding device, place the fixed part (11) on the fixed support plate (25) of the impermeable inverted demoulding device, fix the mold fixing clamp (23) on the connecting column (24) of the impermeable inverted demoulding device through a clamping sleeve, adjust the height and angle of the mold fixing clamp (23) by loosening and tightening the clamping sleeve so that the mold fixing clamp (23) supports the upper end of the fixed part (11), and finally push the lower support plate (27) to drive the demoulding top block (26) to support the lower end of the test block and push the test block out of the fixed part (11), thereby completing the demoulding of the test block.
