Technical Field

[0001] This utility model relates to the field of waste liquid sampling technology, specifically a radioactive waste liquid graded sampling device. Background Technology

[0002] With the continuous development of industry, wastewater and waste liquid generated during industrial production have become one of the most important aspects of environmental protection. Many industrial wastewaters contain a certain amount of radioactive substances, which need to be sampled and analyzed to determine the safety of the wastewater from the corresponding industrial production.

[0003] There are currently no effective solutions to the problems in the relevant technologies.

[0004] 1. Existing radioactive waste liquid classification sampling devices are mostly unable to determine the sampling content during use, and cannot accurately control the amount to be sampled, which is inconvenient for staff to operate and causes unnecessary trouble for staff. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a radioactive waste liquid graded sampling device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A radioactive waste liquid grading sampling device includes a sampling tube, a disc, and a fixing assembly. The bottom of the disc is fixedly connected to a baffle tube via a connecting shaft. The sampling tube has a sampling cavity inside, and the baffle tube is located inside the sampling cavity. The outer wall of the sampling tube has an array of first through slots with equal spacing, and the outer wall of the baffle tube has an array of second through slots with equal spacing. The fixing assembly includes a fixing block, and the outer wall of the disc has an array of fixing slots with one more than the number of first through slots.

[0008] A further improvement of this utility model is that: the number of the first through groove and the second through groove are the same; the second through groove is arrayed and spirally opened on the outer wall of the baffle; the spacing between the fixed grooves opened in the circumferential array is the same as the spacing between the second through grooves opened in the rotating array.

[0009] In the above technical solution, the spacing between the fixed grooves and the spacing between the second through grooves are the same. When the rotating disc drives the baffle, the corresponding second through groove from bottom to top will coincide with the corresponding first through groove, and the corresponding fixed groove will coincide with the fixed block.

[0010] A further improvement of the present invention is that: the upper end of the sampling cylinder is provided with a rotating groove communicating with the sampling cavity, and the connecting shaft that is fixedly connected between the disc and the baffle is rotatably connected inside the rotating groove.

[0011] A further improvement of this utility model is that a connecting rod is fixedly connected to the upper end of the sampling cylinder, and a connecting rotating rod is fixedly connected to the upper end of the disc.

[0012] Using the above technical solution, the connecting rod can be held by the operator to prevent waste liquid from splashing onto the operator's hands, thereby preventing radioactive substances in the waste liquid from causing harm to the human body. The rotation of the connecting rod can drive the disc to drive the baffle to rotate.

[0013] A further improvement of the present invention is that: a support block is fixedly connected to the upper end of the sampling tube, a movable groove is provided inside the support block, a fixed block is slidably connected inside the movable groove, and a pull rod is fixedly connected to one end of the fixed block.

[0015] Using the above technical solution, the limiting block and limiting groove in the solution can limit the fixed block, so that the fixed block can make linear sliding motion and will not disengage from the movable groove.

[0016] A further improvement of this utility model is that a reset spring is fixedly connected to one end of the limiting block, and the end of the reset spring away from the limiting block is fixedly connected to the inner wall of the limiting groove.

[0017] Using the above technical solution, the reset spring in the solution can drive the limit block to drive the fixed block to perform a reset movement, so that the fixed block returns to its original position, thereby making the fixed block snap into the inside of the fixed groove to fix the disc and the baffle. This allows the staff to realize which first and second through grooves are currently overlapping and connected, thereby understanding and controlling the amount that can be sampled.

[0018] A further improvement of the present invention is that: a cover is threadedly engaged at the bottom of the sampling cylinder, a first thread pattern is provided on the outer wall of the bottom of the sampling cylinder, and a second thread pattern is provided on the inner wall of the cover. The cover is threadedly engaged with the bottom of the sampling cylinder through the first thread pattern and the second thread pattern.

[0019] Using the above technical solution, the cover can be opened to facilitate the pouring out of the sample liquid.

[0020] The beneficial effects of this utility model are as follows:

[0021] By rotating the baffle, the corresponding second through groove from bottom to top will coincide with the corresponding first through groove, and the corresponding fixed groove will coincide with the fixed block. The staff can observe which fixed groove the fixed block is aligned with to confirm which first through groove and second through groove are currently connected, thereby understanding and controlling the sampling amount, which is convenient for controlling the sampling amount.

[0022] The reset spring can drive the limit block to move the fixed block to reset, so that the fixed block returns to its original position, thereby fixing the disc and the baffle inside the fixed groove and ensuring the stability during sampling. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] According to an embodiment of the present invention, a radioactive waste liquid grading sampling device is provided. Example 1

[0032] like Figure 1-4 As shown, the radioactive waste liquid grading sampling device according to an embodiment of the present invention includes a sampling cylinder 1, a disc 2, and a fixing component 3. The bottom of the disc 2 is fixedly connected to a baffle 203 via a connecting shaft. The sampling cylinder 1 has a sampling cavity inside, and the baffle 203 is disposed inside the sampling cavity. The outer wall of the sampling cylinder 1 has an array of first through grooves 103 with the same spacing, and the outer wall of the baffle 203 has an array of second through grooves 204 with the same spacing. The fixing component 3 includes a fixing block 301, and the outer wall of the disc 2 has an array of fixing grooves 201 with one more number than the number of first through grooves 103.

[0033] In this embodiment, by rotating the disc 2 to drive the baffle 203, the corresponding second through groove 204 from bottom to top will coincide with the corresponding first through groove 103, and the corresponding fixing groove 201 will coincide with the fixing block 301. The operator can observe which fixing groove 201 the fixing block 301 is aligned with to confirm which first through groove 103 and second through groove 204 are currently overlapping and connected, thereby understanding and controlling the amount that can be sampled, and facilitating the control of the amount of sampled. Example 2

[0034] like Figure 1-4 As shown, in the radioactive waste liquid classification sampling device according to the embodiment of this utility model, the number of first through grooves 103 and second through grooves 204 is the same. The second through grooves 204 are arrayed and spirally opened on the outer wall of the baffle cylinder 203. The spacing between the fixed grooves 201 opened in the circumferential array is the same as the spacing between the second through grooves 204 opened in the rotating array. The upper end of the sampling cylinder 1 is provided with a rotating groove 102 communicating with the sampling cavity. The connecting shaft fixedly connected between the disc 2 and the baffle cylinder 203 is rotatably connected to the inside of the rotating groove 102. The upper end of the sampling cylinder 1 is fixedly connected with a connecting rod 101, and the upper end of the disc 2 is fixedly connected with a connecting rotating rod 202.

[0035] In this embodiment, the spacing between the fixed grooves 201 and the spacing between the second through grooves 204 are the same. When the rotating disc 2 drives the baffle 203, the corresponding second through groove 204 from bottom to top will coincide with the corresponding first through groove 103, and the corresponding fixed groove 201 will coincide with the fixed block 301. The connecting rod 101 can be held by the operator to prevent waste liquid from splashing onto the operator's hands, thereby preventing radioactive substances in the waste liquid from causing harm to the human body. The rotation of the connecting rod 202 can drive the disc 2 to drive the baffle 203 to rotate. Example 3

[0036] like Figure 1-4 As shown, in the radioactive waste liquid grading sampling device according to an embodiment of the present invention, a support block 105 is fixedly connected to the upper end of the sampling cylinder 1. A movable groove 106 is provided inside the support block 105. A fixed block 301 is slidably connected to the inside of the movable groove 106. A pull rod 304 is fixedly connected to one end of the fixed block 301. Limiting grooves 107 are provided on both sides of the inner wall of the movable groove 106. Limiting blocks 302 are fixedly connected to both sides of the fixed block 301. The limiting blocks 302 are slidably connected to the inside of the limiting grooves 107. The fixed block 301... The limiting block 302 and the limiting groove 107 are slidably connected inside the movable groove 106. One end of the limiting block 302 is fixedly connected to a return spring 303. The end of the return spring 303 away from the limiting block 302 is fixedly connected to the inner wall of the limiting groove 107. The bottom of the sampling cylinder 1 is threadedly engaged with a cover 4. The outer wall of the bottom of the sampling cylinder 1 is provided with a first thread pattern 104, and the inner wall of the cover 4 is provided with a second thread pattern 401. The cover 4 is threadedly engaged with the bottom of the sampling cylinder 1 through the first thread pattern 104 and the second thread pattern 401.

[0037] In this embodiment, the limiting block 302 and the limiting groove 107 can limit the fixed block 301, so that the fixed block 301 can slide linearly and will not disengage from the movable groove 106. The reset spring 303 can drive the limiting block 302 to drive the fixed block 301 to perform a reset movement, so that the fixed block 301 returns to its original position, thereby making the fixed block 301 snap into the inside of the fixed groove 201 to fix the disc 2 and the baffle 203. This allows the staff to know which first channel 103 and second channel 204 are currently overlapping and connected, so as to understand and control the amount of sample that can be taken. The cover 4 can be opened to facilitate the pouring out of the sample liquid.

[0038] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0039] In practical applications, rotating the disc 2 drives the baffle 203. At this time, the corresponding second through groove 204 from bottom to top will coincide with the corresponding first through groove 103, and the corresponding fixing groove 201 will coincide with the fixing block 301. The operator can observe which fixing groove 201 the fixing block 301 is aligned with to confirm which first through groove 103 and second through groove 204 are currently aligned and connected. Subsequently, the reset spring 303 can drive the limit block 302 to drive the fixing block 301 to perform a reset movement, so that the fixing block 301 returns to its original position. This allows the fixing block 301 to engage inside the fixing groove 201, fixing the disc 2 and the baffle 203 for sampling. The waste liquid will enter the sampling chamber through the first through groove 103 and the second through groove 204. After sampling, pull the lever 304 to pull the fixing block 301 out of the fixing groove 201, and then rotate the disc 2 so that the fixing block 301 engages inside the leftmost fixing groove 201. At this time, none of the second through grooves 204 are connected to the first through groove 103. Then, take out the sampling cylinder 1. When it is necessary to pour out the waste liquid, simply unscrew the baffle 4.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
