[0002] After the fly ash-based polymer is processed, it is usually necessary to test its water stability in the following way to determine the stability of the fly ash-based polymer in engineering applications involving water and to prove the reliability of the material in a water environment. In actual testing, it is usually necessary to go through sample preparation, immersion, setting time, observation and detection, and result analysis.

[0003] Since the purpose of water stability test is to understand the durability and stability of the polymer in water environment in order to determine its reliability in practical applications, relevant strength tests are usually carried out after immersion, such as compressive strength or flexural strength, to determine the impact of water stability on material properties.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The water stability test device for the fly ash-based polymer is provided with a driving mechanism and an impact mechanism. When the motor drives the driving shaft to rotate in the forward direction, the driving shaft will synchronously drive the ventilation fan blades to rotate, so that the ventilation fan blades extract the air on one side of the motor and continuously inject the air into the storage assembly on the left side, so that the air in the storage assembly continues to accumulate, and the driving shaft will synchronously drive the sealing cover and the exhaust pipe to rotate. When the exhaust pipe rotates 360 degrees, the exhaust pipe will be connected to the through hole on the surface of the aeration shell, so that the gas in the air storage shell quickly enters the aeration shell along the connecting pipe and the docking cover, and then the explosively injected gas will enter the elastic telescopic sleeve along the conduit, so that The elastic telescopic sleeve pops out quickly and pushes the impact block to impact the fly ash-based polymer to be tested. As the drive shaft continues to rotate, when the docking cover slides along the limiting slide groove and is not connected to the aeration shell, the elastic telescopic sleeve will recover under the action of its own elastic force and discharge the gas along the through holes on the surface of the aeration shell, and so on, thereby repeatedly pushing the impact block through aeration to test the strength of the fly ash-based polymer. Since the motor rotation speed is adjustable, the discharged gas pressure is controllable, thereby ensuring that the device can stably test the strength of the fly ash-based polymer multiple times, thereby facilitating the detection of the strength and toughness of the fly ash-based polymer.

[0032] 2. The water stability testing device of the fly ash-based polymer is provided with a driving mechanism and a bending mechanism, so that the motor drives the driving shaft and the second telescopic rod to rotate in the reverse direction. Since the plane of the docking block will be mutually engaged with the plane in the docking groove during the reverse rotation, the second telescopic rod can synchronously drive the docking plate and the transmission wheel to rotate, so that the driving shaft and the transmission wheel synchronously rotate in the reverse direction, and the transmission wheel will synchronously drive the first telescopic rod and the screw rod to rotate. Since the screw rod is connected with a nut outside, the screw rod will gradually push the push block to move toward the fly ash-based polymer during the rotation, and the first telescopic rod will gradually extend, and the push block will squeeze the fly ash-based polymer, so as to test the bending performance of the fly ash-based polymer. By continuously running the motor, the bending angle of the fly ash-based polymer is controlled. When the fly ash-based polymer reaches the specified bending angle, the test is completed. At this time, it is necessary to judge the test data by whether there are cracks on the surface of the fly ash-based polymer and the recovery after bending, thereby reducing the difficulty of the device to test the fly ash-based polymer, reducing the test process, and ensuring the accuracy of the test data.

[0033] 3. The water stability testing device for the fly ash-based polymer is provided with a docking assembly, and the running direction of the motor can be controlled when the motor is running. When the motor drives the drive to rotate in the forward direction, the motor will simultaneously drive the drive shaft and the second telescopic rod to rotate. At this time, the second telescopic rod will drive the docking block to rotate during the rotation process. However, at this time, the rotation direction of the docking block will cause its arc surface to contact with the arc surface in the docking groove, making it difficult for the docking block to drive the docking plate to rotate, so that the motor will not adjust the position of the push block when rotating in the forward direction, thereby ensuring that the device can stably detect the strength of the fly ash-based polymer through the impact block.

[0034] 4. The water stability test device for the fly ash-based polymer is provided with a filter assembly and a pressure assembly. After the strength test of the fly ash-based polymer is completed, the motor needs to be started again. At this time, the ventilation fan blades will draw the gas in the air storage shell through the connecting pipe, and the gas in the two filter boxes connected to the air storage shell will quickly flow into the air storage shell. At the same time, the filter box will draw the air above the test platform through the collecting cover, and some impurities dropped by the fly ash-based polymer after the impact test will enter the collecting cover together with the impurities pushed by the gas and be retained in the filter box by the filter plate, so that the device can automatically recycle the impurities dropped after the fly ash-based polymer is tested, so as to avoid the impurities from continuously adhering to the surface of the test platform and reduce the difficulty of personnel cleaning the device.

When the exhaust pipe 204-4 rotates 360 degrees, at this time, the exhaust pipe 204-4 will be connected to the through hole on the surface of the aeration shell 205-1, so that the gas in the air storage shell 204-1 is quickly discharged. The gas will quickly enter the aeration shell 205-1 along the connecting pipe 204-2 and the docking cover 204-5, and then the explosively injected gas will enter the elastic telescopic sleeve 302 along the conduit 206, so that the elastic telescopic sleeve 302 will quickly pop out and push the impact block 303 to impact the fly ash-based polymer to be tested. As the driving shaft 202 continues to rotate, when the docking cover 204-5 slides along the limiting slide groove 205-2 and is not connected to the aeration shell 205-1, the elastic telescopic sleeve 302 will recover under the action of its own elastic force and discharge the gas along the through holes on the surface of the aeration shell 205-1, and so on, thereby repeatedly pushing the impact block 303 to detect the strength of the fly ash-based polymer through aeration. Since the rotation speed of the motor 201 is adjustable, the pressure of the discharged gas is controllable, thereby ensuring that the device can stably detect the strength of the fly ash-based polymer for multiple times, thereby facilitating the detection of the strength and toughness of the fly ash-based polymer.

During reverse rotation, the plane of the docking block 401-3 will engage with the plane in the docking groove 401-5, so that the second telescopic rod 401-1 can synchronously drive the docking plate 401-4 and the transmission wheel 402-1 to rotate, so that the driving shaft 202 and the transmission wheel 402-1 rotate synchronously in the opposite direction, and the transmission wheel 402-1 will synchronously drive the first telescopic rod 403 and the screw rod 405 to rotate. Since the screw rod 405 is connected with a nut 406, the screw rod 405 will gradually push the push block 409 to move toward the fly ash base polymer during the rotation process, and The first telescopic rod 403 gradually extends, and the push block 409 squeezes the fly ash base polymer, thereby testing the bending performance of the fly ash base polymer.

When the motor 201 drives the drive to rotate in the forward direction, the motor 201 will simultaneously drive the drive shaft 202 and the second telescopic rod 401-1 to rotate. At this time, the second telescopic rod 401-1 will drive the docking block 401-3 to rotate during the rotation process.

The shapes of the docking groove 401-5 and the docking block 401-3 are adapted. The other ends of the second telescopic rod 401-1 and the spring 401-2 are tightly welded to the output shaft on one side of the motor 201, and the other side of the docking plate 401-4 is fixedly connected to the transmission assembly 402. Next, the transmission assembly 402 includes two transmission wheels 402-1, and the two transmission wheels 402-1 are connected by a transmission belt 402-2, wherein the two sides of the transmission wheel 402-1 located at the bottom are fixedly connected to the docking plate 401-4 and the rotator 104 respectively, and the transmission wheel 402-1 located at the top is fixedly connected to the corresponding end of the first telescopic rod 403, and the setting of the spring 401-2 can ensure that the second telescopic tube continues to push the docking block 401-3 to move toward the docking plate 401-4 and the docking groove 401-5, and when the docking block 401-3 is inserted into the docking groove 401-5 and the motor 201 drives the second telescopic rod 401-1 to rotate in the opposite direction, the connection effect of the docking block 401-3 and the docking groove 401-5 is achieved.

[0068] Working principle: When in use, the soaked fly ash-based polymer needs to be installed between two clamps 102 on the test platform 101, and the fly ash-based polymer is fixed by the clamps 102. At this time, the motor 201 can be started to test the toughness and strength of the fly ash-based polymer;

[0069] When the motor 201 is running, the running direction of the motor 201 can be controlled. When the motor 201 drives the driving to rotate in the forward direction, the motor 201 will simultaneously drive the driving shaft 202 and the second telescopic rod 401-1 to rotate. At this time, the second telescopic rod 401-1 will drive the docking block 401-3 to rotate during the rotation process. However, at this time, the rotation direction of the docking block 401-3 will cause its arc surface to contact with the arc surface in the docking groove 401-5, making it difficult for the docking block 401-3 to drive the docking plate 401-4 to rotate.

[0070] When the motor 201 drives the drive shaft 202 to rotate forward, the drive shaft 202 will synchronously drive the ventilation blades 203-3 to rotate, so that the ventilation blades 203-3 extract the air on one side of the motor 201 and continuously inject the air into the storage component 204 on the left, so that the air in the storage component 204 continues to accumulate, and the drive shaft 202 will synchronously drive the sealing cover 204-3 and the exhaust pipe 204-4 to rotate. When the exhaust pipe 204-4 rotates 360 degrees, at this time, the exhaust pipe 204-4 will be connected to the through hole on the surface of the aeration shell 205-1, so that the gas in the air storage shell 204-1 quickly enters along the connecting pipe 204-2 and the docking cover 204-5. The gas injected explosively then enters the elastic telescopic sleeve 302 along the conduit 206, so that the elastic telescopic sleeve 302 pops out quickly and pushes the impact block 303 to impact the fly ash-based polymer to be tested. As the driving shaft 202 continues to rotate, when the docking cover 204-5 slides along the limiting slide groove 205-2 and is not connected to the aeration shell 205-1, the elastic telescopic sleeve 302 will recover under the action of its own elastic force and discharge the gas along the through hole on the surface of the aeration shell 205-1, and so on, thereby repeatedly pushing the impact block 303 to test the strength of the fly ash-based polymer by aeration.

[0071] After the strength test of the fly ash-based polymer is completed, the motor 201 needs to be started again. At this time, the ventilation fan blades 203-3 will extract the gas in the gas storage shell 204-1 through the connecting pipe 204-2, and the gas in the two filter boxes 207-1 connected to the gas storage shell 204-1 will quickly flow into the gas storage shell 204-1. At the same time, the filter box 207-1 will extract the air above the test platform 101 through the collection cover 207-5, and some impurities dropped by the fly ash-based polymer after the impact test will enter the collection cover 207-5 together with the gas push and be retained in the filter box 207-1 by the filter plate 207-3;

[0072] The motor 201 drives the drive shaft 202 and the second telescopic rod 401-1 to rotate in the reverse direction. Since the plane of the docking block 401-3 will be mutually engaged with the plane in the docking groove 401-5 during the reverse rotation, the second telescopic rod 401-1 can synchronously drive the docking plate 401-4 and the transmission wheel 402-1 to rotate, so that the drive shaft 202 and the transmission wheel 402-1 synchronously rotate in the reverse direction, and the transmission wheel 402-1 will synchronously drive the first telescopic rod 403 and the screw rod 405 to rotate. Since the screw rod 405 is connected by a nut 406 The screw rod 405 will gradually push the push block 409 to move toward the fly ash base polymer during the rotation, and the first telescopic rod 403 will gradually extend, and the push block 409 will squeeze the fly ash base polymer, so as to test the bending performance of the fly ash base polymer. By continuously running the motor 201, the bending angle of the fly ash base polymer can be controlled. When the fly ash base polymer reaches the specified bending angle, the test is completed. At this time, it is necessary to judge the test data by whether there are cracks on the surface of the fly ash base polymer and the recovery after bending.
