It will be appreciated that the pump 2, valve 321 and actuator 71 are controlled by an external system, the end of the suction pipe 21 being placed in the waste water to facilitate the suction of the waste water, and the overflow pipe 33 and waste water pipe 40 being piped to a discharge pipe (not shown) for discharging excess waste water.
In this embodiment, the user is before sampling, the buckle 543 is relieved to the accessible, rotate movable clamp plate 542 again, make and separate between fixed clamp plate 541 and the movable clamp plate 542, thereby let the user can put the mouth of pipe of sample container 8 between fixed clamp plate 541 and the movable clamp plate 542, then reset movable clamp plate 542, make fixed clamp plate 541 and movable clamp plate 542 clip and fixed sample container 8, then buckle 543 is buckled, thereby fix sample container 8 at the lower extreme of the sample mouth 54 that corresponds respectively. In the above process, the elasticity of the clamping block 544 can prevent the sampling container 8 from being damaged by clamping, so as to achieve the effect of protecting the sampling container 8.
In the initial state, the first outlet 44 and the second outlet 46 are offset, the valve 321 is closed, and the outlet end of the rotating tube 323 is aligned with a sampling port 54.
During the sample, at first start water pump 2, let water pump 2 go into flow distribution box 3 with waste water pump through suction pipe 21, because in flow distribution box 3, the mouth of pipe of being connected between flow distribution box 3 and the preflow pipe 31 is less than the mouth of pipe of being connected between flow distribution box 3 and the sampling tube 32, waste water just can flow into preflow pipe 31 earlier through self gravity, because through-hole 314 can let floating plate 313 float, waste water just can pass through fender ring 312, through-hole 314 and boss 311 in proper order, flow through preflow pipe 31, get into preflow sleeve 315, flow into preflow sleeve 41 through preflow sleeve 315 at last.
The first discharge port 44 is blocked by the support plate 45 due to the deviation between the first discharge port 44 and the second discharge port 46, so that the waste water cannot flow out of the pre-flow cylinder 41, a sealed space is formed among the piston plate 42, the sealing ring 43 and the pre-flow cylinder 41 due to the edge of the sealing ring 43 being attached to the inner wall of the pre-flow cylinder 41, the waste water flowing out of the pre-flow sleeve 315 is continuously accumulated in the pre-flow cylinder 41, the pre-flow cylinder 41 is finally filled, and then the waste water is lifted into the pre-flow sleeve 315 and the pre-flow pipe 31.
The boss 311 is used for preventing the floating plate 313 from falling into the pre-flow sleeve 315, and as the wastewater in the pre-flow cylinder 41 rises into the pre-flow pipe 31, the floating plate 313 can rise together with the liquid level of the wastewater through the buoyancy of the floating plate 313 until the wastewater is blocked by the blocking ring 312, and the wastewater can continue to be accumulated above the floating plate 313. At this time, since the through hole 314 is blocked by the baffle ring 312, the floating plate 313 is attached to the lower side of the baffle ring 312 due to the buoyancy of the floating plate 313, so that the wastewater below the baffle ring 312 is isolated from the wastewater above the baffle ring 312, that is, during sampling, the initial stage wastewater which is sucked at the beginning is isolated in the pre-flow cylinder 41, so that the initial stage wastewater is separated from the subsequent wastewater and is prevented from being mixed with the subsequent wastewater.
Subsequent waste water is piled up in reposition of redundant personnel case 3, because the mouth of pipe height of overflow pipe 33 is greater than the height of sampling tube 32, when the mouth of pipe height of sampling tube 32 was piled up to waste water in the reposition of redundant personnel case 3, just can flow into in the sampling tube 32, because this moment valve 321 is closed state, waste water can't flow out the sampling tube 32, just can pile up in the sampling tube 32, and the waste water in sampling tube 32 and the reposition of redundant personnel case 3 is the waste water of sample this moment.
To sum up, realized the effect of isolation initial stage waste water when sampling at every turn, can keep apart remaining shallow layer waste water in the tub 21 that absorbs water in advance when sample waste water flows a section of thick bamboo 41, avoid it by the sample or mix with follow-up waste water, lead to the inaccurate phenomenon of detection after the sample, reach the effect that improves the sample degree of accuracy.
When the sampling tube 32 is filled, the waste water continues to accumulate in the diversion box 3, and finally flows out from the overflow tube 33 to discharge the excess waste water. At the moment, the starting time of the water pump 2 can be controlled by the system to ensure that sufficient waste water is sucked, and the water pump 2 is closed after the starting time is over; or when the operator observes the wastewater flowing out of overflow pipe 33, pump 2 is turned off.
After the water pump 2 is turned off, the system control valve 321 is opened, so that the wastewater sampled in the sampling pipe 32 flows into the sampling sleeve 322, and then falls into a sampling port 54 through the rotating pipe 323, so that the wastewater flows into a sampling container 8 through the sampling port 54 to complete one sampling.
After the system control valve 321 is opened for a period of time, the valve 321 is closed to ensure that the sampled wastewater can flow into a sampling container 8 completely. Then the system starts the driver 71, so that the system starts the driver 71 to drive the sampling sleeve 322 to rotate a certain angle through the output shaft 72, so that the outlet end of the rotating pipe 323 rotates to the position between the originally aligned sampling port 54 and the adjacent sampling port 54, and stays for a period of time.
When the sampling sleeve 322 rotates, the sampling sleeve 322 drives the pre-flow sleeve 315 to rotate together through the transmission gear 34, and the pre-flow sleeve 315 pushes the sliding slot 411 through the sliding block 316, so that the pre-flow cylinder 41 rotates together. Since the collecting cylinder 47 is fixed to the housing 1, the collecting cylinder 47 can clamp the screw 66 through the clamping block 49 and the clamping groove 67, so that the screw 66 is fixed to the support plate 45 and cannot rotate, and the pre-flow cylinder 41 and the support plate 45 rotate relatively.
When the rotary pipe 323 stays between the two sampling ports 54, the first discharge port 44 is aligned with a second discharge port 46, so that the waste water in the preflow cylinder 41 falls into the collecting cylinder 47 through the first discharge port 44 and the second discharge port 46 and is discharged through the waste water pipe 40. Because the waste water in the pre-flow cylinder 41 is reduced, the floating plate 313 descends along with the liquid level of the waste water, so that the waste water remained in the shunt box 3 and the pre-flow pipe 31 can flow into the pre-flow cylinder 41 and then flow into the collecting cylinder 47, and is discharged through the waste water pipe 40, and the effect that the pre-flow assembly 4 is driven to discharge the waste water remained in the pre-flow cylinder 41 and the shunt box 3 after the waste water sampling is completed is achieved, so as to prepare for the next sampling.
The rotary tube 323 stays between the two sampling ports 54 for a period of time to ensure that all the residual wastewater in the pre-flow cylinder 41 and the flow dividing box 3 is discharged, and then the system starts the driver 71 again to drive the sampling sleeve 322 to rotate until the rotary tube 323 moves to the position where the outlet end faces the sampling port 54 adjacent to the originally aligned sampling port 54 and stops. At this time, the rotary tube 323 is aligned with the sampling port 54 of another sampling container 8, and the first discharge port 44 and the second discharge port 46 are shifted again, so that the first discharge port 44 is blocked by the support plate 45 again, that is, the preflow assembly 4 and the sampling assembly 5 are restored to the initial state, and the next sampling can be performed.
Further, as shown in fig. 8, in the process of rotating the outlet end of the rotating pipe 323 from one sampling port 54 to the other sampling port 54 clockwise, the fixed teeth 52 engage the elastic member 551 between the two sampling ports 54, so that the fixed teeth 52 push the elastic member 551, and the rotating shaft 55 rotates until the cover 552 is stopped by the edge of the rotating wheel 51 and cannot rotate any further. At this time, on the one hand, the elastic member 551 can be disengaged from the fixed teeth 52 by the elastic deformation of the elastic member 551, thereby preventing the rotation wheel 51 from being caught; on the other hand, the cover 552 can block the sampling port 54 above the sampling container 8 after sampling is completed, and close the upper opening of the sampling container 8, so as to reduce the influence of the external environment on the sampled wastewater in the sampling container 8.
When the driver 71 rotates one turn, the sampling container 8 is completely sampled, and the system prompts the operator to take the sample.
After the worker takes the sample and replaces the sampling container 8, the driver 71 needs to rotate reversely for one circle, so that the fixed tooth 52 drives the rotating shaft 55 to rotate reversely until the stop lever 56 blocks the cover plate 552, and the cover plate 552 can open the sampling port 54; alternatively, the rotation shaft 55 is manually rotated to rotate the cover plate 552 into contact with the stopper 56, thereby opening the sampling port 54.
In this embodiment, the volume of the sampling tube 32 can be changed by changing the shape of the sampling tube 32 or by changing the thickness of the sampling tube 32, so that the amount of wastewater to be sampled can be changed. Accordingly, when the waste water is pumped in, the amount of the waste water flowing into the sampling pipe 32 is changed along with the change of the volume of the sampling pipe 32, so that the amount of the waste water flowing into the sampling container 8 is changed, and the effect of changing the amount of the waste water for sampling is achieved.
In addition, in this embodiment, the user can also change the amount of waste water that can be accumulated by changing the size of the space formed between the preflow cylinder 41 and the piston plate 42; the specific operation is as follows: through rotating the screw sleeve 65, because the collecting cylinder 47 blocks the screw 66 through the fixture block 49 and the fixture groove 67 and can not rotate, the screw sleeve 65 is in threaded connection with the screw 66, the screw 66 is driven to extend and contract in the screw sleeve 65, the screw 66 can drive the pre-flow cylinder 41 to move up and down through the support plate 45, because the position of the piston plate 42 is unchanged, the up and down movement of the pre-flow cylinder 41 can change the size of a space formed between the pre-flow cylinder 41 and the piston plate 42, and the amount of waste water which can be accumulated in the pre-flow cylinder 41 can be changed.
When deeper wastewater is sampled, the water inlet end of the water suction pipe 21 can extend into the deeper wastewater, and under the condition that more shallow wastewater exists in the water suction pipe 21, the pre-flow cylinder 41 can be moved downwards, the amount of wastewater which can be stored in the pre-flow cylinder 41 is increased, so that more initial wastewater can be stored, the initial wastewater can be completely stored in the pre-flow cylinder 41, and the accuracy of deep wastewater sampling is ensured; when the shallow waste water of sample, the end of intaking of pipe 21 that absorbs water can stretch into in the shallow waste water, can be with flowing a section of thick bamboo 41 upward movement in advance, and the waste water volume that can deposit in flowing a section of thick bamboo 41 in advance reduces, can deposit less initial stage waste water promptly, and after initial stage waste water all flowed into a section of thick bamboo 41 in advance, a section of thick bamboo 41 that flows in advance can be filled with the back fast, gets into the sample step more fast, promotes the sampling speed.
In conclusion, the effect of adapting to different depths of wastewater sampling by changing the capacity of the pre-flow cylinder 41 is achieved.
In this embodiment, when the screw sleeve 65 rotates clockwise, the preflow cylinder 41 moves upward, and the capacity of the preflow cylinder 41 is reduced; when the screw housing 65 rotates counterclockwise, the preflow cylinder 41 moves downward, increasing the capacity of the preflow cylinder 41.
When the height of the preflow cylinder 41 is adjusted to a proper level, the bolt 69 is inserted through a second fixing hole 64 and into the first fixing hole 62 aligned with the second fixing hole 64, and the bolt 69 fixes the screw housing 65, thereby fixing the height of the preflow cylinder 41.
In addition, in the present embodiment, the following operations are also possible: after the user wraps the pull cord 68 around the screw housing 65, the plug 69 is inserted into a threaded hole 75 in a pull wheel 73, and the plug 69 is threadedly secured in the threaded hole 75.
After once taking a sample and accomplishing, the rotatory in-process of output shaft 72 just can drive traction wheel 73 and tighten up haulage rope 68, and haulage rope 68 is tightened up the process of pull, just can drive screw rod cover 65 rotatory, makes screw rod cover 65 through the threaded connection with screw rod 66, drives screw rod 66 and stretches out and draws back in screw rod cover 65, adjusts the height of a class section of thick bamboo 41 in advance to the volume of adjustment initial segment waste water makes after taking a sample at every turn, and the volume of initial segment waste water all can change. And through changing the direction that the haulage rope 68 twines on screw rod cover 65, can change when haulage rope 68 is restrainted by traction wheel 73, drive the rotatory direction of screw rod cover 65, namely control after sampling each time, the volume of initial stage waste water increases gradually or dwindles.
If after sampling at every turn, need increase the degree of depth of waste water sampling, shallow layer waste water in the corresponding suction tube 21 can increase gradually, after the anticlockwise winding of haulage rope 68 on screw rod sleeve 65 this moment, fix bolt 69 on traction wheel 73 again, sample at this moment at every turn and accomplish the back, when traction wheel 73 is rotatory, just can be through binding up haulage rope 68, drive screw rod sleeve 65 anticlockwise rotation, thereby reduce and flow a 41 height in advance, reach the effect that increases the capacity of a 41 in advance gradually, thereby adapt to the volume of the shallow layer waste water that constantly increases.
If after sampling at every turn, can constantly reduce the degree of depth of waste water sampling, shallow layer waste water that corresponds in the pipe 21 that absorbs water can reduce gradually, after clockwise winding haulage rope 68 on screw sleeve 65 this moment, fix bolt 69 on traction wheel 73 again, the back is accomplished in every turn sampling this moment, when traction wheel 73 is rotatory, just can be through binding up haulage rope 68, drive screw sleeve 65 clockwise rotation, thereby increase and flow a section of thick bamboo 41 height in advance, reach the effect that reduces the capacity of a section of thick bamboo 41 in advance one by one, thereby the volume of the constantly reduced shallow layer waste water of adaptation.
In conclusion, the effect of adapting to continuous sampling of different depths of wastewater is achieved.
The speed of the drawstring 68 is also varied by the user securing the latch 69 to a different diameter of the drawstring wheel 73.
The larger the diameter of the traction wheel 73 is, the more the traction rope 68 is bundled after sampling each time, the more the rotation amount of the screw sleeve 65 is, and the more the variation amount of the height of the preflow cylinder 41 is, that is, after sampling each time, the larger the variation amplitude of the wastewater amount in the initial stage is, so that the sampling depth difference is adapted to the larger case;
the smaller the diameter of the traction wheel 73 is, the more the traction rope 68 is bound after sampling every time, the less the rotation amount of the screw sleeve 65 is, the smaller the variation of the height of the pre-flow cylinder 41 is, namely, after sampling every time, the smaller the variation amplitude of the initial-stage wastewater quantity is, and the smaller the depth difference of the sampling is adapted.
In conclusion, the condition of adapting to different sampling depth differences is achieved.
