Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a water quality monitoring and sampling device used in wastewater treatment plants. Background Technology

[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of the daily lives of ordinary people.

[0003] In the process of sewage treatment, it is often necessary to sample and monitor the sewage in the sewage tank to determine whether the treated sewage meets the discharge standards. In many existing devices, sampling is simply done at a fixed depth or position at the edge of the sewage tank, which cannot comprehensively reflect the water quality of different levels and areas in the sewage tank, resulting in inaccurate monitoring results. Therefore, it is necessary to design a water quality monitoring and sampling device for sewage treatment plants. Utility Model Content

[0006] Furthermore, the lifting assembly includes a motor, a take-up roller, a guide roller, and a chain. The upper end of the first support frame is rotatably connected to the take-up roller via a first support base, and the front end of the first support base is fixedly installed with a motor. The output shaft end of the motor is fixedly connected to the take-up roller. The left end of the first support frame and the interior of the first support frame are rotatably connected to guide rollers via second support bases. A chain is wound around the circumference of multiple guide rollers and the take-up roller, and the chain passes through the first support frame. A through hole for the chain to move is opened on the left end face of the first support frame. The end of the chain away from the take-up roller passes through the bottom end of the first support frame and is fixedly installed on the top of the left sampling assembly.

[0007] Furthermore, the sampling assembly includes a sampling cylinder, a waterproof electric push rod, a connecting frame, a pull rod, and a piston. The bottom end of the support rod and the end of the chain away from the take-up roller are both fixedly connected to the connecting frame. The sampling cylinder and the waterproof electric push rod are fixedly connected inside the connecting frame, and the waterproof electric push rod is located at the upper end of the sampling cylinder. The piston is slidably connected inside the sampling cylinder, and the top end of the piston is fixedly connected to the pull rod. The pull rod extends upward through the sampling cylinder, and the output end of the waterproof electric push rod is fixedly installed at the top end of the pull rod.

[0008] Furthermore, a sealing ring is fixedly connected inside the sampling tube, and the sealing ring is tightly fitted to the pull rod.

[0009] Furthermore, a counterweight is fixedly connected to the circumferential surface of the sampling cylinder.

[0010] Furthermore, a scale is provided on the circumferential surface of the sampling tube.

[0011] Furthermore, the connector includes a fixed plate, a slot, a top plate, a rod, a spring, and a connecting plate. The fixed plate is fixedly connected to the upper end of the fixed frame, and the fixed plate and the fixed frame are an integral structure. Multiple slots are provided on the upper surface of the fixed plate. The connecting plate is fixedly connected to the circumferential surface of the rotating shaft.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with the existing technology, this water quality monitoring sampling device applied to sewage treatment plants can sample sewage at different depths in the sewage tank of sewage treatment plants through the cooperation of the lifting component and the sampling component. Specifically, the lifting component can drive the left sampling component to rise and fall, so that the left sampling component can be inserted into the sewage tank at different depths, thereby sampling sewage at different depths. By sampling sewage at different depths and then monitoring it, the final sewage monitoring results can be more accurate.

[0015] 2. Compared with existing technologies, this water quality monitoring sampling device applied to sewage treatment plants, through the cooperation of a rotating shaft, a first support frame, a second support frame, a sampling component, a sliding hole, a threaded shaft, a nut, and a support rod, can sample sewage at different locations at the same depth in a sewage tank within a sewage treatment plant. Specifically, the nut can be loosened, and then the second support frame can be extended and retracted to change the relative position between the second and first support frames, thereby changing the position of the support rod and the sampling component on the right. After adjustment, the first support frame can be rotated around the rotating shaft, which in turn drives the second support frame and the sampling component to rotate around the rotating shaft until the desired position is reached. This facilitates the sampling and monitoring of sewage at different locations at the same height within the sewage tank using the sampling component. This sampling and monitoring method allows for the monitoring of water quality in different areas, ultimately resulting in more accurate sewage monitoring results. Attached Figure Description

Detailed Implementation

[0027] Reference Figure 1-9This utility model provides a water quality monitoring and sampling device for a sewage treatment plant, comprising a fixed frame 1, a rotating shaft 2 rotatably connected inside the fixed frame 1, a connector 11 installed between the rotating shaft 2 and the fixed frame 1, and the connector 11 used to fix the rotating shaft 2, a first support frame 3 fixedly connected to the top of the rotating shaft 2, a second support frame 4 slidably connected inside the first support frame 3, a support rod 6 slidably connected inside the second support frame 4, a disc 9 fixedly connected to the top of the support rod 6, a handle 10 fixedly connected to the upper end of the disc 9, and a lifting assembly 7 installed at the upper end of the first support frame 3. Sampling components 5 are installed at the left end of the support rod 6, and at the bottom of both the lifting assembly 7 and the support rod 6. The sampling components 5 are used to collect sewage, and the lifting assembly 7 is used to adjust the lifting of the sampling components 5. A sliding hole 12 is provided on the front end face of the first support frame 3. A threaded shaft 15 is slidably connected inside the sliding hole 12. The threaded shaft 15 passes through the sliding hole 12 and extends to the front end of the first support frame 3. The threaded shaft 15 is fixedly installed at the front end of the second support frame 4. A nut 16 is threadedly connected to the circumferential surface of the threaded shaft 15. The nut 16 is located at the front end of the first support frame 3 and fits tightly against it. During operation, this invention can sample sewage at different depths at the same location, and can also sample and monitor sewage at different locations at the same depth. The two methods work together to sample and monitor sewage at different levels and areas in the sewage tank. This sampling and monitoring method makes the final monitoring results more accurate, and the entire process does not require operators to get too close to the sampler, eliminating the danger of falling into the sewage tank.

[0028] Furthermore, the lifting assembly 7 includes a motor 701, a take-up roller 702, a guide roller 703, and a chain 704. The upper end of the first support frame 3 is rotatably connected to the take-up roller 702 through a first support base, and the front end of the first support base is fixedly installed with the motor 701. The output shaft end of the motor 701 is fixedly connected to the take-up roller 702. The left end of the first support frame 3 and the interior of the first support frame 3 are rotatably connected to the guide roller 703 through a second support base. The circumferential surfaces of the multiple guide rollers 703 and the take-up roller 702 are jointly wound with the chain 704, and the chain 704 passes into the first support frame 3. The left end face of the first support frame 3 has a through hole for the chain 704 to move. The end of the chain 704 away from the take-up roller 702 passes through the bottom end of the first support frame 3 and is fixedly installed on the top of the left sampling assembly 5. During operation, the motor 701 can drive the winding roller 702 to rotate. At this time, the chain 704 can be gradually wound up or unwound with the cooperation of multiple guide rollers 703, thereby completing the lifting and lowering adjustment of the left sampling component 5 so that the sampling component 5 can be used to take samples at different depths in the sewage tank.

[0029] Furthermore, the sampling assembly 5 includes a sampling cylinder 501, a waterproof electric push rod 502, a connecting frame 503, a pull rod 504, and a piston 505. The bottom end of the support rod 6 and the end of the chain 704 away from the take-up roller 702 are both fixedly connected to the connecting frame 503. The sampling cylinder 501 and the waterproof electric push rod 502 are fixedly connected inside the connecting frame 503, and the waterproof electric push rod 502 is located at the upper end of the sampling cylinder 501. The piston 505 is slidably connected inside the sampling cylinder 501. The top end of the piston 505 is fixedly connected to the pull rod 504. The pull rod 504 extends upward through the sampling cylinder 501, and the output end of the waterproof electric push rod 502 is fixedly installed at the top end of the pull rod 504. During operation, the waterproof electric push rod 502 is an IP69K linear push rod. When in use, the waterproof electric push rod 502 retracts, and with the cooperation of the pull rod 504, it will drive the piston 505 to move upward. At this time, the sewage in the sewage tank can enter the sampling cylinder 501, thereby completing the sampling work.

[0030] Furthermore, a sealing ring is fixedly connected inside the sampling cylinder 501, and the sealing ring fits tightly against the pull rod 504. During operation, the presence of the sealing ring improves the sealing effect between the sampling cylinder 501 and the pull rod 504, reducing the possibility of sewage entering the sampling cylinder 501 along the gap between the pull rod 504 and the sampling cylinder 501, thus affecting sampling.

[0031] Furthermore, a counterweight 8 is fixedly connected to the circumferential surface of the sampling cylinder 501. During operation, the presence of the counterweight 8 increases the weight of the sampling cylinder 501, allowing it to smoothly enter the sewage for sampling instead of floating.

[0032] Furthermore, a scale is provided on the circumference of the sampling cylinder 501. During operation, the scale allows operators to visually see the exact amount of wastewater collected from the sampling cylinder 501.

[0033] Furthermore, the connector 11 includes a fixed plate 1101, a slot 1102, a top plate 1103, a plug rod 1104, a spring 1105, and a connecting plate 1106. The fixed plate 1101 is fixedly connected to the upper end of the fixed frame 1, and the fixed plate 1101 and the fixed frame 1 are an integral structure. Multiple slots 1102 are opened on the upper end surface of the fixed plate 1101. The connecting plate 1106 is fixedly connected to the circumferential surface of the rotating shaft 2. The plug rod 1104 is slidably connected inside the connecting plate 1106, and the plug rod 1104 can be inserted into the slot 1102. The top end of the plug rod 1104 is fixedly connected to the top plate 1103. The spring 1105 is sleeved on the circumferential surface of the plug rod 1104. One end of the spring 1105 is fixedly connected to the top plate 1103, and the other end of the spring 1105 is fixedly connected to the connecting plate 1106. During operation, before adjusting the angle of the first support frame 3, hold the top plate 1103 and move it upwards, causing the insertion rod 1104 to move in the direction of disengaging from the slot 1102. At the same time, the spring 1105 is stretched until the insertion rod 1104 is completely disengaged from the corresponding slot 1102. Then, the first support frame 3 can be rotated around the rotating shaft 2 to adjust the angle of the first support frame 3, the second support frame 4, and the sampling component 5. This allows the sampling component 5 to be adjusted to different positions for sampling. Adjusting the sampling component 5 to a direction away from the sewage tank also facilitates the subsequent removal of the sample from the sampling tube 501. After the angle adjustment is completed, release the top plate 1103. Under the action of the spring 1105, the insertion rod 1104 is inserted into the corresponding slot 1102, thus fixing the rotating shaft 2. This ensures that the rotating shaft 2 is stably located within the fixing frame 1 and is not prone to arbitrary deflection, thus facilitating stable sampling operations in the future.

[0034] Furthermore, a threaded groove 14 is provided on the upper end face of the second support frame 4, and a circular hole is provided on the upper end face of the disc 9. The circular hole is located directly above the threaded groove 14, and a screw 13 is installed inside the circular hole. The screw 13 is inserted into the threaded groove 14 along the circular hole. During operation, after the screw 13 is installed along the threaded groove 14, it can be ensured that the sampling component 5 on the right side is stably connected to the second support frame 4 with the cooperation of the support rod 6 and the disc 9, and is not easily moved.

[0035] Working principle:

[0036] In use, the mounting bracket 1 is fixedly installed on the side of the sewage treatment tank in the sewage treatment plant. First, operate the connector 11 to move the insert rod 1104 away from the slot 1102. Then, rotate the first support frame 3, causing the first support frame 3 to rotate the second support frame 4 to a position convenient for operators. Next, loosen the nut 16 and adjust the extension and retraction of the first and second support frames 3 and 4 to change their relative positions, thereby changing the position of the sampling component 5 on the right. This facilitates the subsequent sampling of sewage at the same depth from different locations by the right-side sampling component 5. After adjusting the position, retighten the nut 16 to ensure that the second support frame 4 is stably located within the first support frame 3 and not easily moved. Then, rotate the first support frame 3 again around the rotating shaft 2, causing it to rotate the sampling component 5 back into the sewage tank. After the angle adjustment is complete, insert the insert rod 1104 in the connector 11 into the corresponding slot 1102 to fix the rotating shaft 2 and prevent the rotating shaft 2 from interfering with the first support frame 3. The support frame 3 can be rotated freely, and then the lifting component 7 can be controlled to operate, driving the left sampling component 5 to rise and adjust, so that the left sampling component 5 can move to different depths for sampling. After sampling is completed, the lifting component 7 is controlled again to move the left sampling component 5 to the top of the sewage tank. Then the angle of the first support frame 3 is adjusted so that the sampling component 5 can be rotated to a position that is convenient for the operator to take out the sample. Then the screw 13 is rotated to move it away from the thread groove 14. With the help of the support rod 6, the handle 10 can be held to drive the right sampling component 5 to rise, so that the right sampling component 5 can also be removed from the sewage tank, so that the operator can take out the sample inside the sampling tube 501 and carry out subsequent monitoring work. In this utility model, since the operator can sample sewage at different depths at the same location, or sample and monitor sewage at different locations at the same depth, the two can be combined to sample and monitor sewage at different levels and areas in the sewage tank. This sampling and monitoring method can make the final monitoring results more accurate.

[0037] It should be noted that the waterproof electric push rod 502 and the motor 701 are respectively connected to external control terminals, which can be controlled to open and close by external control terminals. The control terminals are not shown in the figure, but they are existing technology and will not be described in detail here.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
