[0002] In the nuclear energy industry, medical radioactive material applications and other radioactive waste treatment fields, the monitoring and control of wastewater discharge is an important task to protect the environment and public health. At present, when the detection device is in use, since the wastewater contains a large amount of impurities, in order to prevent the impurities inside it from affecting the test results, it is generally filtered by a filter plate. However, some impurities will inevitably accumulate on its surface after long-term filtration.

[0003] In the prior art, in order to clean impurities on the filter plate, before the wastewater test is required, the tester usually needs to disassemble the filter plate for cleaning. However, the filter plate is usually fixed by bolts, which requires the tester to use tools to disassemble the filter plate and then clean it, thereby increasing downtime and affecting the test efficiency.

[0004] Therefore, a radioactive wastewater discharge detection device and monitoring system are needed to solve the problem that existing monitoring devices require detection personnel to use tools to disassemble and clean the filter plate, resulting in increased downtime. Utility Model Content

[0024] Embodiment 1

[0025] See also Figures 1 to 7 The utility model provides a technical solution: a radioactive wastewater discharge detection device, including a detection box 1, a water pump 2 is installed on the top of the detection box 1, a placement box 6 is arranged on the inner wall of the detection box 1, two detector bodies 12 are installed inside the placement box 6, a wastewater tank 5 is plugged into the lower side of the detection box 1, a filter plate 9 is installed on the top of the placement box 6, a moving block 7 is arranged on the upper side of the inner wall of the detection box 1, a brush 11 is installed on the bottom of the moving block 7, and a recovery box 3 is installed on the right side of the detection box 1.

[0026] The inspector first turns the hand crank at the right end of the screw 8 to drive the moving block 7 to slide along the outer side of the slide rod 10, so that the moving block 7 can move smoothly to the right, and then drive the brush 11 to clean the surface of the filter plate 9. At the same time, in the process of moving to the right, it drives these impurities to move to the right to the inside of the recovery box 3, so as to facilitate the collection of impurities. After the cleaning is completed, the inspector starts the water pump 2 to pump the wastewater to be tested into the inside of the placement box 6, and filters it through the filter plate 9, so as to reduce the impurities entering the inside of the placement box 6. Then the inspector checks the test results through the detection of the two detector bodies 12, which is convenient for the inspector to use and reduces the downtime. After the detection is completed, the solenoid valve at the bottom of the placement box 6 is opened to discharge the tested wastewater into the inside of the wastewater tank 5 to prevent these wastewaters from causing harm to the environment.

[0027] Embodiment 2

[0028] On the basis of Example 1, in order to enable the moving block 7 to drive the brush 11 to clean the filter plate 9 while moving, a screw 8 is inserted into the rear side of the detection box 1, and the right end of the screw 8 passes through the right side of the recovery box 3, a slide rod 10 is installed on the front side of the detection box 1, and the right end of the slide rod 10 is installed on the front side of the recovery box 3, the rear side of the moving block 7 is threadedly connected to the outside of the screw 8, and the front side of the moving block 7 is slidably connected to the outside of the slide rod 10.

[0029] By rotating the lead screw 8, the movable block 7 moves to the right following the rotation of the lead screw 8, and the front side of the movable block 7 slides on the outside of the slide rod 10, so that the movable block 7 can slide smoothly during the reciprocating movement left and right, thereby conveniently driving the brush 11 to clean the surface of the filter plate 9, and at the same time, it can also sweep these impurities into the inside of the recovery box 3, so as to facilitate subsequent maintenance personnel to carry out maintenance.

[0030] Embodiment 3

[0031] On the basis of Example 2, in order to facilitate subsequent maintenance personnel to clean the recycling box 3, a baffle 4 is hinged on the right side of the recycling box 3, a slide groove 16 is opened on the rear side of the recycling box 3, a limit block 15 is installed inside the slide groove 16, two springs 14 are installed on the front side of the limit block 15, a card block 13 is fixedly connected to the middle part of the limit block 15, and a plug plate 17 is inserted on the right side of the recycling box 3.

[0032] After long-term use, a large amount of impurities will accumulate inside the recycling box 3. The maintenance personnel first pulls out the plug plate 17 to the right. Due to the elastic force of the two springs 14, the limit block 15 is driven to slide to the rear side of the slide slot 16, and the card block 13 is driven to move backward, thereby releasing the baffle 4. The maintenance personnel then opens the baffle 4 to clean the impurities inside the recycling box 3. After cleaning, the baffle 4 is reset and the plug plate 17 is inserted into the recycling box 3. Since the rear end of the card block 13 fits against the plug plate 17, the card block 13 is driven to move forward and plugged into the rear side of the baffle 4, making it convenient for the maintenance personnel to clean the recycling box 3.

[0033] Embodiment 4

[0034] A monitoring system includes a radioactive wastewater discharge detection device.

[0035] During actual use, the inspector first turns the hand crank at the right end of the screw 8. Since the rear side of the moving block 7 is threadedly connected to the outer side of the screw 8, the moving block 7 is driven to move to the right, and the front side of the moving block 7 slides on the outer side of the slide rod 10, so that the moving block 7 can move smoothly to the right, thereby driving the brush 11 to clean the surface of the filter plate 9. At the same time, in the process of moving to the right, it drives these impurities to move to the right to the inside of the recovery box 3, so as to facilitate the collection of impurities. After cleaning, the inspector starts the water pump 2 to pump the wastewater to be tested into the inside of the placement box 6, and filters it through the filter plate 9, thereby reducing the entry of impurities into the inside of the placement box 6. Subsequently, the inspector checks the test results through the detection of the two detector bodies 12, which is convenient for the inspector to use and reduces the downtime. After the detection is completed, the solenoid valve at the bottom of the placement box 6 is opened to discharge the tested wastewater into the inside of the wastewater tank 5 to prevent these wastewaters from causing harm to the environment.
