[0044] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] The embodiments of the present application provide a water pollution monitoring sampling device, which can solve the problem of low cleaning efficiency of the sampling tank in the related art.

[0046] See also Figures 1 to 12 A water pollution monitoring sampling device comprises: a sampling tank 1, wherein the sampling tank 1 comprises a water outlet pipe 11 and a plurality of tank walls 12, wherein the plurality of tank walls 12 are arranged around the sampling tank, and a storage space for storing a sample is provided between the plurality of tank walls 12, wherein the water outlet pipe 11 is connected to the tank wall 12, and the water outlet pipe 11 is connected to the storage space;

[0047] A closing cover 2 is provided with a fixing tube 3 and a plurality of fixing structures 4 in the middle of the closing cover 2. The fixing structure 4 includes a slot 41 and an insert 42. The slot 41 is provided on the tank wall 12. The insert 42 is slidably connected to the fixing tube 3 and can be inserted into the slot 41.

[0048] In this embodiment, there are four tank walls 12 and four fixed structures 4, and two water outlet pipes 11. The two water outlet pipes 11 are located on two different tank walls 12, and the two tank walls 12 on which the water outlet pipes 11 are installed are arranged opposite to each other.

[0049] When assembling the tank walls 12, first place the four tank walls 12 around the fixed tube 3. At this time, the bottoms of the four tank walls 12 are assembled into a disc and the sides of the four tank walls 12 are assembled into a ring. Then rotate the closing cover 2 and the fixed tube 3 so that each fixing structure 4 corresponds to a tank wall 12, so that the staff can insert the mobile plug-in 42 into the slot 41, thereby fixing the tank wall 12 on the fixed tube 3. It should be pointed out that a water inlet is provided on the closing cover 2, and the opening of the water inlet is vertically oriented. After the four tank walls 12 are assembled, the closing cover 2 is covered on the four tank walls 12. The staff can place the present application in the sampling water by lifting the handles on both sides of the closing cover 2, and the liquid enters the storage space through the water inlet;

[0050] After the staff pours the sample out of the storage space, when it is necessary to clean the tank wall 12, they only need to remove the plug 42 from the slot 41 first. At this time, the staff can separate the tank wall 12 from the fixed tube 3. The staff only needs to rinse the removed tank wall 12 with clean water.

[0051] Furthermore, in this embodiment, the fixing structure 4 further includes a top block 43, a first spring 44, a sleeve 45, an inner tube 46, and a second spring 47;

[0052] The top block 43 is connected to the tank wall 12 and is in close contact with the plug-in 42 . The two ends of the first spring 44 are respectively connected to the plug-in 42 and the fixing tube 3 .

[0053] The sleeve 45 is in communication with the fixed tube 3, and the inner tube 46 is slidably connected to the sleeve 45. The inner tube 46 is connected to the plug 42. The inner tube 46 has a first position and a second position. When the inner tube 46 moves from the first position to the second position, one end of the inner tube 46 moves from the fixed tube 3 to the sleeve 45. The two ends of the second spring 47 are respectively connected to the inner tube 46 and the sleeve 45.

[0054] A driving rod 48 is slidably connected in the fixing tube 3 , and a placement slot 49 is provided on the driving rod 48 ;

[0055] A chute extending from top to bottom is provided on the tank wall 12, and a groove is formed at the tail end of the chute. The top block 43 is arranged in the groove. After the four tank walls 12 are placed around the fixed tube 3, the closing cover 2 is placed on the four tank walls 12. At the same time, the inner tube 46 is stuck in the chute and descends with the closing cover 2. When the closing cover 2 is completely covered, the inner tube 46 is located in the groove. At this time, the second spring 47 continuously provides a force to the inner tube 46 toward the first position, so that the inner tube 46 remains in the first position. The inner tube 46 is stuck in the placement groove 49, pressing the drive rod 48 downward. Figure 9As shown, the placement groove 49 will squeeze the inner tube 46 to move from the first position to the second position. During this process, the inner tube 46 continues to move into the groove, and the top block 43 in the groove will squeeze the plug-in 42, squeezing the plug-in 42 into the slot 41 until the inner tube 46 moves to the second position, and the plug-in block 42 is inserted into the slot 41. At the same time, the inner tube 46 will support the outer wall of the driving rod 48 to ensure that the inner tube 46 and the plug-in 42 will not move, thereby fixing the fixed tube 3 to the tank wall 12.

[0056] Furthermore, in this embodiment, a T-shaped block 5 is provided on the water outlet pipe 11;

[0057] A closing member 6 is provided in the water outlet pipe 11. The closing member 6 includes a cover 61, a cylinder 64, a third spring 65, and a sealing ring 66. A T-slot 62 is provided on the cover 61. A U-slot 63 is provided on the cover 61. The T-slot 62 is connected to the U-slot 63. The T-block 5 can pass through the T-slot 62.

[0058] The cylinder 64 is rotatably connected to the cover 61. The third spring 65 is located inside the cylinder 64. The third spring 65 is connected to the cylinder 64 and the cover 61 respectively. The sealing ring 66 is connected to the cylinder 64 and is in close contact with the inner wall of the water outlet pipe 11.

[0059] Before assembling the four tank walls 12, after the four tank walls 12 are placed around the fixed pipe 3, it is necessary to first install the closure member 6 on the outlet pipe 11, and the cylinder 64 is matched with the outlet pipe 11. First, the sealing ring 66 is inserted into the outlet pipe 11, and then the cylinder 64 is inserted into the outlet pipe 11. The sealing ring 66 plays a sealing role to prevent the sample from flowing out of the outlet pipe 11. The cylinder 64 has a guiding role, which facilitates the subsequent cover body 61 to completely cover the pipe mouth of the outlet pipe 11. In the process of fitting the cover body 61 to the pipe mouth of the outlet pipe 11, it is necessary to adjust the angle of the cover body 61, align the T-slot 62 with the T-block 5, so that the T-block 5 passes through the T-slot 62. After the T-block 5 passes through the T-slot 62, rotate the cover body 61 so that the T-block 5 enters the U-slot 63, thereby fixing the cover body 61 and the sealing ring 66 to the outlet pipe 11;

[0060] It should be pointed out that the third spring 65 in this application is a torsion spring. After the T-block 5 passes through the T-slot 62, the cover body 61 will automatically slide into the U-slot 63 under the influence of the third spring 65, which is convenient for the staff to operate.

[0061] The closure member 6 further includes a locking ring 67, a locking tongue 68 and a fourth spring 69;

[0062] The locking ring 67 is connected to the cover 61 and is arranged around the fixing tube 3. The fixing tube 3 is provided with a first locking opening, and the locking ring 67 can be inserted into the first locking opening.

[0063] The locking tongue 68 is slidably connected to the locking ring 67. The driving tube is provided with a second locking opening, and the locking tongue 68 can be inserted into the second locking opening. The two ends of the fourth spring 69 are respectively connected to the locking tongue 68 and the ring.

[0064] During the process of installing the closure on the water outlet pipe 11, the two locking rings 67 surround the fixed tube 3, and the locking ring 3 is inserted into the first locking port. At this time, since the driving rod 49 is not pressed down, the locking tongue 68 presses against the driving rod 49, and the fourth spring 69 is squeezed. When the driving rod 49 is pressed down, the second locking port moves to a position corresponding to the locking tongue 68, and the fourth spring bounces the locking tongue 68 into the second locking port. Since the moving direction of the locking tongue 68 is perpendicular to the moving direction of the driving rod 49, the locking tongue 68 fixes the driving rod 49. At the same time, after the cover body 61 is fixed on the water outlet pipe 11, the driving rod 49 is prevented from automatically rising after being pressed down.

[0065] Here's how this application works:

[0066] When assembling the present application, first place the four tank walls 12 around the fixed pipe 3. During the placement process, it is necessary to pay attention to aligning the inner tube 46 with the slide groove, and then slide the inner tube 46 into the groove. Then insert the closure 6 into the outlet pipe 11, plug the sealing ring 66 into the outlet pipe 11, and then plug the cylinder 64 into the outlet pipe 11. In the process of fitting the cover body 61 with the outlet pipe 11, it is necessary to adjust the angle of the cover body 61 and align the T-slot 62 with the T-block 5. The T-block 5 is passed through the T-slot 62. After the T-block 5 passes through the T-slot 62, the cover 61 is rotated so that the T-block 5 enters the U-slot 63, thereby fixing the cover 61 and the sealing ring 66 to the outlet pipe 11. During the installation of the closure on the outlet pipe 11, the two locking rings 67 surround the fixed pipe 3, and the locking ring 3 is inserted into the first locking port. At this time, the driving rod 48 is pressed down, and the placement groove 49 squeezes the inner pipe 46 from the first position to the second position. In this process, The inner tube 46 moves continuously into the groove, and the top block 43 in the groove squeezes the plug 42, squeezing the plug 42 into the slot 41 until the inner tube 46 moves to the second position and the plug 42 is inserted into the slot 41. At the same time, the inner tube 46 presses against the outer wall of the driving rod 48 to ensure that the inner tube 46 and the plug 42 do not move, thereby fixing the fixed tube 3 to the tank wall 12. At the same time, the second lock moves to a position corresponding to the lock tongue 68, and the fourth spring bounces the lock tongue 68 into the second lock mouth. Since the moving direction of the lock tongue 68 is perpendicular to the moving direction of the driving rod 49, the lock tongue 68 fixes the driving rod 49. At the same time, after the cover body 61 is fixed to the water outlet pipe 11, the driving rod 49 is prevented from automatically rising after being pressed down. It should be pointed out that the present application fixes the position of the fixed tube 4 and the driving rod 48 by fixing the cover body 61 to the water outlet pipe 11, and then fixes the four tank walls 12 and the cover body to ensure the stability of the device.

[0067] After the device is installed, the staff can place the application in the sampled water by lifting the handles on both sides of the closing cover 2, and the liquid enters the storage space through the water inlet. After the staff pours the sample out of the storage space, when it is necessary to clean the tank wall 12, first remove the cover body 61 from the outlet pipe 11, and then lift the drive rod 48. After that, under the action of the first spring 44, the plug-in 42 leaves the slot 41, and under the action of the second spring 47, the inner tube 4 moves from the second position to the first position. At this time, the four tank walls 12 are separated from the fixed tube 3, and the staff only needs to rinse the disassembled tank wall 12 with clean water.
