Example

[0024] Reference Figure 1-4 A printing and dyeing wastewater sampling device comprises a chassis 1, a sampling tube 2 is installed on the top wall of the chassis 1, and sampling holes 201 are evenly opened on the side wall below the sampling tube 2, so that wastewater sampling can be carried out from multiple points. A filter cover 3 is detachably installed on the top of the chassis 1 and located outside the sampling tube 2. The floating impurities in the wastewater can be filtered through the setting of the filter cover 3; a bracket 4 is provided on one side of the chassis 1, and a clamping mechanism is provided between the bracket 4 and the sampling tube 2. The clamping mechanism comprises two groups of clamping plates 5 with adjustable spacing. The two groups of clamping plates 5 can clamp and position the sampling tube 2. Through the adjustable spacing of the clamping plates 5, sampling tubes 2 of different sizes can be clamped and fixed, and the applicability is relatively wide.

[0025] In this embodiment, a first motor 6 is installed in the middle of the top wall of the sampling tube 2. The output shaft at the output end of the first motor 6 passes through the top wall of the sampling tube 2 and is connected to a threaded rod 7. The bottom end of the threaded rod 7 is rotatably connected to the inside of a groove opened on the inner bottom wall of the sampling tube 2. The outer surface of the threaded rod 7 is threadedly connected to a piston plate 8, and the outer portion of the piston plate 8 slides on the inner wall of the sampling tube 2.

[0026] It should be noted that when the power is turned on, the first motor 6 drives the threaded rod 7 to rotate, and the threaded rod 7 drives the piston plate 8 threadedly connected to it to move upward inside the sampling tube 2. The pressure change in the sampling cavity inside the sampling tube 2 is utilized to allow the printing and dyeing wastewater to enter the sampling cavity through multiple sampling holes 201 after being filtered by the filter cover 3.

[0027] In this embodiment, the clamping mechanism also includes a limit plate 9, a second motor 10 is installed at one end of the limit plate 9, a sliding cavity 901 is opened in the middle of one side of the limit plate 9, and the output shaft at the output end of the second motor 10 passes through one end of the limit plate 9 and is connected to a bidirectional screw 11. The outside of the bidirectional screw 11 is symmetrically provided with a threaded block 12, the threaded block 12 is threadedly connected to the bidirectional screw 11, the threaded block 12 is slidably connected to the inner side of the sliding cavity 901, the outer end of the threaded block 12 is fixedly connected to a connecting column 13, the clamping plate 5 is connected to the end of the connecting column 13, and the two groups of connecting columns 13 are connected and fixed by a fixing rod 14.

[0028] It should be noted that when the power is turned on, the second motor 10 drives the bidirectional screw 11 to rotate, and the bidirectional screw 11 drives the two threaded blocks 12 threadedly connected to it to approach each other, and the two threaded blocks 12 drive the connecting column 13 and the two clamping plates 5 connected to it to approach each other until the sampling tube 2 is clamped and fixed. When the upper group of clamping plates 5 approach each other, under the action of the fixing rod 14 connecting the two groups of connecting columns 13, the two lower clamping plates 5 approach synchronously, thereby achieving clamping and fixing of different positions on the sampling tube 2, and the clamping effect is stable.

[0029] In this embodiment, a top plate 15 is fixedly connected to the top of the bracket 4, a cylinder 16 is fixedly installed at the bottom of the top plate 15, a fixing plate 17 is connected to the end of the actuator rod of the cylinder 16, and one end of the fixing plate 17 is fixedly connected to the side wall of one of the limit plates 9.

[0030] It should be noted that, the downward extension of the actuator rod of the cylinder 16 pushes the fixed plate 17 downward, so that the clamped and fixed sampling tube 2 moves toward the inside of the wastewater pool. When the bottom of the sampling tube 2 is located in the sampling area, sampling can begin. By continuing to extend the actuator rod of the cylinder 16, the sampling tube 2 can be placed in a deeper sampling area, thereby sampling printing and dyeing wastewater of different depths. At the same time, the contractility of the telescopic member 19 can further stably support the device to maintain the stability of the device during the falling process.

[0031] In this embodiment, a bottom plate 18 is fixedly connected to the side wall below the bracket 4 , a telescopic member 19 is fixedly connected to the top of the bottom plate 18 , and a telescopic end of the telescopic member 19 is connected to the bottom wall of the fixed plate 17 .

[0032] It should be noted that the contractility of the telescopic member 19 can be used to provide further stable support for the device, thereby maintaining the stability of the device during the falling process.

[0033] The working principle of the utility model is as follows: the operator first fixes the bracket 4 and the bottom plate 18 to the side of the printing and dyeing wastewater pool, the chassis 1 is located above the printing and dyeing wastewater pool, the sampling tube 2 is installed on the chassis 1, and the filter cover 3 is installed outside the sampling tube 2. Then the power is turned on and the second motor 10 drives the bidirectional screw 11 to rotate. The bidirectional screw 11 drives the two threaded blocks 12 threadedly connected to it to approach each other. The two threaded blocks 12 drive the connecting column 13 and the two clamping plates 5 connected to it to approach each other until the sampling tube 2 is clamped and fixed. When the upper group of clamping plates 5 are close to each other, under the action of the fixing rod 14 connecting the two groups of connecting columns 13, the two clamping plates 5 at the bottom are synchronized to approach each other, thereby achieving clamping and fixing of different positions on the sampling tube 2. The clamping effect is stable, and the sampling tube 2 is clamped and fixed. After being fixed, the downward extension of the cylinder 16 actuator rod pushes the fixing plate 17 downward, so that the clamped and fixed sampling tube 2 moves toward the inside of the wastewater pool. When the bottom of the sampling tube 2 is located in the sampling area, the power is turned on and the first motor 6 drives the threaded rod 7 to rotate. The threaded rod 7 drives the piston plate 8 threadedly connected thereto to move upward inside the sampling tube 2. By utilizing the pressure change in the sampling cavity inside the sampling tube 2, the printing and dyeing wastewater passes through the filter cover 3 and then enters the sampling cavity through multiple sampling holes 201. By continuing to extend the cylinder 16 actuator rod, the sampling tube 2 can be placed in a deeper sampling area, so that printing and dyeing wastewater at different depths can be sampled. At the same time, the contractility of the telescopic member 19 can further stably support the device to maintain the stability of the device during the falling process.

[0034] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
