Description

Technical Field

[0001] This utility model relates to the field of wastewater extraction technology, and in particular to an extraction device for wastewater detection. Background Technology

[0002] Wastewater refers to wastewater discharged from domestic and industrial sources that has been polluted to a certain extent. Water that has lost its original function is simply called wastewater. Wastewater is caused by the introduction of new substances into the water or changes in external conditions, leading to water deterioration and the inability to maintain its original function. Some factories, in order to save costs, secretly discharge untreated wastewater, which seriously harms the natural environment and affects ecological stability.

[0003] The locations of wastewater discharges from some factories that violate regulations are often quite hidden, and it is difficult for pedestrians to approach the discharge outlets directly. This makes it difficult for sampling personnel to collect wastewater samples for testing, and it increases the safety risks for the sampling personnel themselves during the wastewater collection process. This is not conducive to the collection and testing of wastewater, and consequently, it is not conducive to the investigation and treatment of wastewater. Utility Model Content

[0004] The purpose of this application is to provide an extraction device for wastewater testing, in order to solve the problem mentioned in the background art that the location of illegally discharged wastewater is generally hidden, and the location of the discharge outlet is difficult for pedestrians to approach directly. This makes it difficult for sampling personnel to extract wastewater samples for testing, and increases the safety risks for the sampling personnel themselves during the wastewater extraction process, which is not conducive to the extraction and testing of wastewater, and thus not conducive to the investigation and treatment of wastewater.

[0005] To achieve the above objectives, this application provides the following technical solution: an extraction device for wastewater testing, comprising a sampling cylinder, a top cover threadedly connected to the top of the sampling cylinder, an inlet pipe fixedly connected to the bottom of the sampling cylinder, a piston slidably installed in the sampling cylinder, a first traction rope fixed to the top of the piston, a fixing ring fixed to the other end of the first traction rope after passing through the top cover, a first connecting rope fixed to the bottom of the piston, a sealing plug fixed to the other end of the first connecting rope after passing through the inlet pipe, a through hole for the first traction rope to pass through the top cover, a connecting post fixed to the top cover, an extension assembly installed on the connecting post, a take-up assembly installed on the extension assembly, the extension assembly for delivering the sampling cylinder to the wastewater sampling point, and the take-up assembly for pulling the piston upwards in the sampling cylinder.

[0006] Furthermore, a second connecting rope is fixed to the bottom of the sealing plug, and a counterweight ball is fixed to the other end of the second connecting rope.

[0007] Furthermore, an auxiliary rod is fixed on the top cover, and a sleeve is fitted over the outside of the top cover. The top cover and the sleeve are threaded together, and a package bag is fixedly connected to the bottom of the sleeve. The package bag is fitted over the outside of the sampling cylinder.

[0008] Furthermore, the extension assembly includes a carrier cylinder, an extension rod is slidably inserted into the open side of the carrier cylinder, a connecting cylinder is fixed to the end of the extension rod away from the carrier cylinder, a connecting post is threadedly connected to the connecting cylinder, a stud is threadedly connected to the carrier cylinder, the stud is used to lock the carrier cylinder and the extension rod, and a knob is fixed to the bottom end of the stud.

[0009] Furthermore, auxiliary rings are fixed on the top cover, the carrier cylinder, and the connecting cylinder, and a handle is fixed on the other side of the carrier cylinder.

[0010] Furthermore, a limiting post is fixed on the extension rod, and a limiting groove for sliding the limiting post is provided on the carrier cylinder.

[0011] Furthermore, the take-up assembly includes a winding reel, which is rotatably mounted on a carrier drum. A second traction rope is wound on the winding reel, one end of which is fixedly mounted on the winding reel, and the other end of which is fixed with a safety buckle.

[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, the sampling cylinder can be sent to areas inaccessible to the sampling personnel by means of the extension component. The take-up component can pull the first traction rope to move the piston upward in the sampling cylinder, causing the sewage to be sucked into the sampling cylinder along the inlet pipe. As the piston continues to move upward, the piston will pull the sealing plug upward with the help of the first connecting rope until the sealing plug enters the inside of the inlet pipe and seals the inlet pipe, thus completing the sewage extraction work, making sewage extraction safer and more convenient.

[0013] In this invention, the auxiliary rod provides a point of leverage for the sampling personnel to hold the top cover and connect the sleeve to the top cover with threads, so that the packaging bag covers the outside of the sampling tube. In this way, the sewage adhering to the outside of the sampling tube can be prevented from overflowing, thus ensuring the safety of sampling.

[0014] In this invention, a safety buckle hooks onto a fixing ring, and rotating the winding reel can wind up the second traction rope. This causes the second traction rope to move the safety buckle and the fixing ring toward the location of the winding reel. The fixing ring pulls the first traction rope to move toward the outside of the sampling cylinder, causing the first traction rope to pull the piston upward in the sampling cylinder, which facilitates the suction of sewage into the sampling cylinder to complete the sampling work.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: Reference Figure 1-4 The wastewater testing extraction device shown includes a sampling cylinder 1, a top cover 2 threadedly connected to the top of the sampling cylinder 1, and an inlet pipe 3 fixedly connected to the bottom of the sampling cylinder 1. A piston 4 is slidably installed in the sampling cylinder 1. A first traction rope 5 is fixed to the top of the piston 4, and the other end of the first traction rope 5 passes through the top cover 2 and is fixed to a fixing ring 6. A first connecting rope 7 is fixed to the bottom of the piston 4, and the other end of the first connecting rope 7 passes through the inlet pipe 3 and is fixed to a sealing plug 8. A second connecting rope 9 is fixed to the bottom of the sealing plug 8. The other end of 9 is fixed with a counterweight ball 10. The sealing plug 8 is connected to the counterweight ball 10 through the second connecting rope 9. The counterweight ball 10 can move the sealing plug 8 down into the sewage by its own weight, so that the sampling tube 1 can sample the sewage. The top cover 2 is provided with a through hole for the first traction rope 5 to pass through. A connecting column is fixed on the top cover 2. An extension component is installed on the connecting column. A take-up component is installed on the extension component. The extension component is used to send the sampling tube 1 to the sewage sampling point. The take-up component is used to pull the piston 4 up in the sampling tube 1. With the help of the extension component, the sampling cylinder 1 can be sent to an area that the sampling personnel cannot reach. The take-up component can pull the first traction rope 5 to move the piston 4 upward in the sampling cylinder 1, causing the sewage to be sucked into the sampling cylinder 1 along the inlet pipe 3. As the piston 4 continues to move upward, the piston 4 will pull the sealing plug 8 upward with the help of the first connecting rope 7 until the sealing plug 8 enters the interior of the inlet pipe 3 and seals the inlet pipe 3, thus completing the sewage extraction.

[0020] The top cover 2 is fixed with an auxiliary rod 11, and a sleeve 13 is sleeved on the outside of the top cover 2. The top cover 2 and the sleeve 13 are threaded together. A wrapping bag 12 is fixedly connected to the bottom of the sleeve 13. The wrapping bag 12 is sleeved on the outside of the sampling cylinder 1. With the help of the force point provided by the auxiliary rod 11, the sampling personnel can hold the top cover 2 and thread the sleeve 13 to the top cover 2 so that the wrapping bag 12 covers the outside of the sampling cylinder 1. In this way, the sewage adhering to the outside of the sampling cylinder 1 can be prevented from overflowing, ensuring the safety of sampling.

[0021] The extension assembly includes a carrier cylinder 14, an extension rod 15 is slidably inserted into the open side of the carrier cylinder 14, a connecting cylinder 18 is fixed to the end of the extension rod 15 away from the carrier cylinder 14, a connecting post is threadedly connected to the connecting cylinder 18, a stud 16 is threadedly connected to the carrier cylinder 14, the stud 16 is used to lock the carrier cylinder 14 and the extension rod 15, a knob 17 is fixed to the bottom end of the stud 16, an auxiliary ring 20 is fixed to the top cover 2, the carrier cylinder 14 and the connecting cylinder 18, the auxiliary ring 20 is set to facilitate the movement of the second traction rope 24 and the first traction rope 5, a handle 19 is fixed to the other side of the carrier cylinder 14, a limit post 21 is fixed to the extension rod 15, and a limit groove 22 is opened on the carrier cylinder 14 for the limit post 21 to slide. Pulling the extension rod 15 outward can adjust the combined length of the carrier cylinder 14 and the extension rod 15. Turning the knob 17 can lock the carrier cylinder 14 and the extension rod 15 in place by turning the connecting cylinder 18. After the length of the extension assembly is adjusted, the sampling cylinder 1 can be sent to the location of the sewage for convenient sewage sampling. The cooperation of the limiting column 21 and the limiting slide 22 can prevent the carrier cylinder 14 and the extension rod 15 from completely separating.

[0022] The winding assembly includes a winding reel 23, which is rotatably mounted on the carrier drum 14. A second traction rope 24 is wound on the winding reel 23. One end of the second traction rope 24 is fixedly mounted on the winding reel 23, and the other end of the second traction rope 24 is fixed with a safety buckle 25. By using the safety buckle 25 to hook the fixing ring 6, the winding reel 23 can be rotated to wind up the second traction rope 24, so that the second traction rope 24 drives the safety buckle 25 and the fixing ring 6 to move towards the location of the winding reel 23. The fixing ring 6 pulls the first traction rope 5 to move towards the outside of the sampling cylinder 1, so that the first traction rope 5 pulls the piston 4 to move upward in the sampling cylinder 1, making it convenient to suck the sewage into the sampling cylinder 1 to complete the sampling work.

[0023] Working principle of this utility model: Screw the connecting post on the top cover 2 into the inside of the connecting cylinder 18. The connecting post and the connecting cylinder 18 are threaded together, so that the top cover 2 can be fixed on the connecting cylinder 18. The sampling cylinder 1 is threadedly connected to the top cover 2, so that the sampling cylinder 1 is indirectly fixed on the connecting cylinder 18. Pull the extension rod 15 outward to adjust the combined length of the carrier cylinder 14 and the extension rod 15 so that the extension assembly reaches the specified length. Turn the knob 17 to drive the connecting cylinder 18 to rotate. Use the connecting cylinder 18 to lock the carrier cylinder 14 and the extension rod 15. Pull the safety buckle 25 to hook it onto the fixing ring 6. After preparation, the staff holds the handle 19 and uses the extension assembly to send the sampling cylinder 1 to the sewage discharge point, so that the inlet pipe 3 on the sampling cylinder 1 is submerged in the sewage. The counterweight ball 10 uses its own weight to drive the sealing plug 8 into the sewage. The winding reel 23 is rotated to wind the second traction rope 24, so that the second traction rope 24 pulls the first traction rope 5 to move to the outside of the sampling cylinder 1. The first traction rope 5 pulls the piston 4 upward, so that the sewage is sucked into the interior of the sampling cylinder 1 along the inlet pipe 3. At the same time, the piston 4 pulls the sealing plug 8 upward with the help of the first connecting rope 7, so that the sealing plug 8 enters the interior of the inlet pipe 3 to seal the inlet pipe 3. Then, the sampling cylinder 1 is retrieved with the extension assembly, the packaging bag 12 is taken out, and the packaging bag 12 is put on the outside of the sampling cylinder 1, so that the sleeve 13 is threadedly connected to the top cover 2. Then, the connecting post on the top cover 2 is removed from the connecting cylinder 18, and the extension assembly is folded and stored, thus completing the sewage extraction work.
