Description

Technical Field

[0001] The utility model relates to the technical field of sewage and wastewater quality detection, and specifically relates to a sewage and wastewater quality sampling device. Background Technique

[0002] A sewage and wastewater quality sampling device is a device used to obtain samples from sewage or wastewater for water quality analysis. Usually, the sampling device will use a specific mechanical device (such as a roller, rope, chain or steel cable, etc.) to lower the sampler or sampling bottle to the required sampling depth by moving up and down, and then lift it up. This device can help monitor and evaluate the pollution degree and water quality change of the water body, and is one of the important tools in environmental monitoring and management;

[0003] Traditional sewage and wastewater quality sampling devices usually fix ropes, chains or steel cables on the sampler to ensure that they are firmly connected together, and then drive the roller equipped with ropes, chains or steel cables to rotate through a motor to control the lowering height and speed of the sampler;

[0004] Traditional sewage and wastewater quality sampling devices have the following problems: The roller driven by the motor can only realize the vertical up and down movement of the sampler, and cannot perform horizontal or other complex movements, resulting in the phenomenon that ropes or chains may accumulate during the wire winding process. Especially when the movement is frequent or the speed is fast, this accumulation phenomenon will affect the stability and operation efficiency of the sampling device, and it cannot adaptively adjust the tension of ropes, chains or steel during wire winding and direction changing. For this reason, we propose a sewage and wastewater quality sampling device. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, and provide a sewage and wastewater quality sampling device, which can effectively prevent rope accumulation, ensure the stability of the sewage and wastewater quality sampling device during high-frequency or high-speed movement, and at the same time can adaptively adjust the tension of the sampler to be always appropriate during wire releasing and wire winding processes, and can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A sewage and wastewater quality sampling device, including a sampling outer shell, a mounting frame, a roller and a wire winding mechanism;

The middle part of the rope extends into the inside of the tension adjustment mechanism, and the right end of the rope is fitted and installed with the mounting ring;

[0010] Wire winding mechanism: It is arranged at the right end inside the sampling housing. The wire winding mechanism is fitted and installed with the rope, which can effectively prevent the rope from piling up, ensure the stability of the sewage and wastewater quality sampling device during high-frequency or high-speed movement, and at the same time can adaptively adjust the tension of the sampler to be always appropriate during wire releasing and wire winding, improving the operation stability and overall efficiency of the sewage and wastewater quality sampling device.

[0011] Furthermore, it further includes a single-chip microcomputer. The single-chip microcomputer is arranged at the left end of the front side of the sampling housing. The input end of the single-chip microcomputer is electrically connected to an external power supply, which is convenient for controlling the operation of each electrical appliance.

[0012] Furthermore, it further includes a motor 1. The motor 1 is installed on the middle part of the front side of the sampling housing through bolts. The rear end of the output shaft of the motor 1 is fixedly connected to the front end of the roller. The input end of the motor 1 is electrically connected to the output end of the single-chip microcomputer to realize the winding and unwinding of the rope.

[0013] Furthermore, the wire winding mechanism includes a limiting piece, a rotating shaft, an internally threaded block and a reciprocating lead screw. The reciprocating lead screw is rotatably connected between the front and rear inner walls at the right end of the sampling housing. The middle part of the reciprocating lead screw is threadedly connected with the internally threaded block. Two rotating shafts are fixedly connected to the upper surface of the internally threaded block. The middle part of the rope is fitted and installed between the two rotating shafts. Limiting pieces are respectively fixedly connected to the tops of the two rotating shafts to realize reciprocating motion.

[0014] Furthermore, the wire winding mechanism further includes a limiting rod, a pulley and a limiting groove. The limiting rod is fixedly connected to the lower surface of the internally threaded block. The bottom end of the limiting rod is rotatably connected with the pulley. The limiting groove is opened at the right end of the bottom wall of the sampling housing. The inner wall of the limiting groove is slidably connected with the outer surface of the pulley to limit the movement of the internally threaded block.

[0015] Furthermore, the wire winding mechanism further includes a motor 2. The motor 2 is installed on the right end of the front side of the sampling housing through bolts. The rear end of the output shaft of the motor 2 is fixedly connected to the front end of the reciprocating lead screw.

[0017] Furthermore, the tension adjustment mechanism further includes sliding holes, sliding columns and springs. The sliding columns are fixedly connected between the front and rear inner walls of the sliding grooves. The sliding holes are respectively opened at the upper and lower ends of the sliding blocks. The inner walls of the sliding holes are slidably connected to the middle parts of the adjacent sliding columns. The springs are fixedly connected between the side of the sliding block away from the center of the guiding groove and the inner wall of the adjacent sliding groove.

[0019] Furthermore, it further includes universal wheels, which are respectively installed at the four corners of the lower surface of the sampling housing through bolts, facilitating the movement of the sewage and wastewater quality sampling device to the required location.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: The sewage and wastewater quality sampling device has the following advantages:

[0021] 1. After the sampler completes sampling, the single-chip microcomputer controls the operation of the first motor. The output shaft of the first motor drives the roller to rotate in the reverse direction, causing the rope to rotate reversely, resulting in the rope gradually winding back into the interior of the roller. At the same time, the single-chip microcomputer controls the operation of the second motor. The output shaft of the second motor rotates to drive the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw makes the internally threaded block move back and forth along the axis of the reciprocating lead screw, and drives the pulley to move back and forth along the inner wall of the limiting groove, so that the rope can be guided back and forth between the two rotating shafts. Thus, through the back-and-forth movement, the rope can be evenly wound on the roller, avoiding the phenomenon of rope accumulation that may occur during high-frequency or high-speed movement, ensuring the stability of the sewage and wastewater quality sampling device during operation, and avoiding damage or stoppage of the sewage and wastewater quality sampling device caused by accumulation.

[0022] 2. When the rope is being wound in, with the reciprocating movement of the rope driving the sliding block to move along the sliding column in the sliding groove, the movement of the sliding block compresses or stretches the adjacent springs to adjust the tension of the rope, ensuring that the rope always maintains an appropriate tension state during the pay-out and winding-in processes of the sampler, so that the tension of the rope can be adjusted in real time.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1-6 , this embodiment provides a technical solution: a sewage and wastewater water quality sampling device, including a sampling housing 3, a mounting bracket 8, a roller 13 and a wire winding mechanism 6;

[0032] Sampling housing 3: A guiding groove 7 is provided in the middle of its right side surface. A tension adjusting mechanism 12 is arranged inside the guiding groove 7. The tension adjusting mechanism 12 includes a sliding opening 121, a sliding block 122 and a sliding groove 123. The sliding grooves 123 are respectively provided at the upper and lower ends of the inner wall of the guiding groove 7. A sliding block 122 is slidably connected between the inner walls of the sliding grooves 123. A sliding opening 121 is provided in the middle of the sliding block 122. The middle part of the rope 11 is cooperatively installed inside the sliding opening 121. The tension adjusting mechanism 12 further includes a sliding hole 124, a sliding column 125 and a spring 126. The sliding columns 125 are fixedly connected between the front and rear inner walls of the sliding groove 123. The sliding holes 124 are respectively provided at the upper and lower ends of the sliding block 122. The inner walls of the sliding holes 124 are slidably connected to the middle parts of the adjacent sliding columns 125. The springs 126 are fixedly connected between the side of the sliding block 122 away from the center of the guiding groove 7 and the inner wall of the adjacent sliding groove 123. The springs 126 are sleeved on the outer surfaces of the sliding columns 125. When the rope 11 is being wound in, with the reciprocating movement of the rope 11, the sliding block 122 is driven to move along the sliding column 125 in the sliding groove 123. The movement of the sliding block 122 compresses or stretches the adjacent springs 126 to adjust the tension of the rope 11, ensuring that the rope 11 always maintains an appropriate tension state during the pay-out and winding-in processes of the sampler 9, so that the tension of the rope 11 can be adjusted in real time. It further includes a single-chip microcomputer 2, and the single-chip microcomputer 2 is arranged at the left end of the front side surface of the sampling housing 3. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply. It further includes a cover 1, and the cover 1 is buckled on the top end of the sampling housing 3. It further includes universal wheels 4, and the universal wheels 4 are respectively installed at the four corners of the lower surface of the sampling housing 3 by bolts. Push the sampling housing 3, and it can be moved to a designated location through the universal wheels 4;

[0033] Mounting frame 8: It is fixedly connected to the lower end of the right side surface of the sampling housing 3. A sampler 9 is clamped inside the mounting frame 8. An installation ring 10 is fixedly connected to the upper surface of the sampler 9. Take out the sampler 9 from the mounting frame 8;

[0034] Roller 13: It is rotatably connected between the front and rear inner walls in the middle of the sampling housing 3. A rope 11 is sleeved on the outer surface of the roller 13. The middle part of the rope 11 extends into the inside of the tension adjustment mechanism 12. The right end of the rope 11 is fitted and installed with the mounting ring 10. It also includes a first motor 5. The first motor 5 is installed on the middle part of the front side of the sampling housing 3 by bolts. The rear end of the output shaft of the first motor 5 is fixedly connected to the front end of the roller 13. The input end of the first motor 5 is electrically connected to the output end of the single-chip microcomputer 2. Open the cover 1 of the device, install the rope 11 on the roller 13, stretch the end to between the two rotating shafts 63, and pass through the sliding opening 121 on the slider 122, and finally connect to the mounting ring 10 on the sampler 9. By controlling the operation of the first motor 5 through the single-chip microcomputer 2, the rotation of the output shaft of the first motor 5 drives the rotation of the roller 13. The rotation of the roller 13 causes the rope 11 to gradually be released from the inside of the roller 13, so that the sampler 9 can descend to the required water depth. When the sampler 9 finishes sampling, by controlling the operation of the first motor 5 through the single-chip microcomputer 2, the output shaft of the first motor 5 drives the roller 13 to rotate in the reverse direction, causing the rope 11 to rotate in the reverse direction, resulting in the rope 11 gradually winding back into the inside of the roller 13;

[0035] Wire winding mechanism 6: It is arranged at the right end inside the sampling housing 3. The wire winding mechanism 6 is fitted and installed with the rope 11. The wire winding mechanism 6 includes a limit piece 62, a rotating shaft 63, an internally threaded block 64, and a reciprocating lead screw 65. The reciprocating lead screw 65 is rotatably connected between the front and rear inner walls at the right end of the sampling housing 3. The middle part of the reciprocating lead screw 65 is threadedly connected with the internally threaded block 64. The upper surface of the internally threaded block 64 is fixedly connected with two rotating shafts 63. The middle part of the rope 11 is fitted and installed between the two rotating shafts 63. The top ends of the two rotating shafts 63 are respectively fixedly connected with limit pieces 62. The wire winding mechanism 6 also includes a limit rod 66, a pulley 67, and a limit groove 68. The limit rod 66 is fixedly connected to the lower surface of the internally threaded block 64. The bottom end of the limit rod 66 is rotatably connected with the pulley 67. The limit groove 68 is opened at the right end of the bottom wall of the sampling housing 3. The inner wall of the limit groove 68 is slidably connected with the outer surface of the pulley 67. The wire winding mechanism 6 also includes a second motor 61. The second motor 61 is installed on the right side of the front side of the sampling housing 3 by bolts. The rear end of the output shaft of the second motor 61 is fixedly connected to the front end of the reciprocating lead screw 65. The input end of the second motor 61 is electrically connected to the output end of the single-chip microcomputer 2. By controlling the operation of the second motor 61 through the single-chip microcomputer 2, the rotation of the output shaft of the second motor 61 drives the rotation of the reciprocating lead screw 65. The rotation of the reciprocating lead screw 65 causes the internally threaded block 64 to move back and forth along the axis of the reciprocating lead screw 65, and drives the pulley 67 to move back and forth along the inner wall of the limit groove 68, so that the rope 11 can be guided back and forth between the two rotating shafts 63, so that the rope 11 can be evenly wound on the roller 13 through the back-and-forth movement.

[0036] The working principle of a sewage and wastewater quality sampling device provided by the present utility model is as follows: First, open the cover 1 of the device, install the rope 11 on the roller 13, stretch the end to between the two rotating shafts 63, and pass it through the sliding opening 121 on the slider 122, and finally connect it to the mounting ring 10 on the sampler 9. Then, take out the sampler 9 from the mounting frame 8, and then push the sampling housing 3, and move it to the designated location through the universal wheels 4. Control the operation of the first motor 5 through the single-chip microcomputer 2. The rotation of the output shaft of the first motor 5 drives the rotation of the roller 13. The rotation of the roller 13 causes the rope 11 to gradually be released from the inside of the roller 13, so that the sampler 9 can descend to the required water depth. When the sampler 9 finishes sampling, control the operation of the first motor 5 through the single-chip microcomputer 2. The output shaft of the first motor 5 drives the roller 13 to rotate in the reverse direction, causing the rope 11 to rotate in the reverse direction, resulting in the rope 11 gradually being wound back into the inside of the roller 13. At the same time, control the operation of the second motor 61 through the single-chip microcomputer 2. The rotation of the output shaft of the second motor 61 drives the rotation of the reciprocating lead screw 65. The rotation of the reciprocating lead screw 65 causes the internally threaded block 64 to reciprocate back and forth along the axis of the reciprocating lead screw 65, and drives the pulley 67 to reciprocate back and forth along the inner wall of the limiting groove 68, so that the rope 11 can be reciprocally guided between the two rotating shafts 63, and thus the rope 11 can be evenly wound on the roller 13 through the reciprocating motion back and forth. However, when the rope 11 is being wound in, with the reciprocating motion of the rope 11 driving the slider 122 to move along the sliding column 125 in the sliding groove 123, the movement of the slider 122 compresses or stretches the adjacent spring 126 to adjust the tension of the rope 11, ensuring that the rope 11 always maintains an appropriate tension state during the process of the sampler 9 paying out and winding in the line, so that the tension of the rope 11 can be adjusted in real time.

[0037] It should be noted that the specific model of the single-chip microcomputer 2 disclosed in the above embodiments is S7-200, and it is recommended to select YBE4-0.75KW-2 for the first motor 5 and the second motor 61. The single-chip microcomputer 2 controls the operation of the first motor 5 and the second motor 61 by using the commonly used methods in the prior art.

[0038] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
