Description

Technical Field

[0001] The utility model belongs to the technical field of sewage sampling, and particularly relates to a multi-level sewage sampling device. Background Art

[0002] The Chinese utility model patent currently announced as CN216050866U discloses a sewage sampling device, which is provided with a shell, which is barrel-shaped, has side walls and an open inner cavity, and a sampler for collecting sewage, and is detachably arranged in the inner cavity. The above arrangement realizes a replaceable and reusable sewage sampling device. After collecting a sewage sample, the clean sampler can be replaced in time, and the replaced sampler can be taken back to the laboratory for cleaning and reused. The sampler has a simple structure and high practical value, and can better meet the monitoring needs of sewage sampling.

[0003] Although the patent allows the sampler to be disassembled, it can only sample sewage according to its depth during the sampling process. Sampling of sewage at different depths requires multiple times, which makes the operation process cumbersome and wastes time. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-level sewage sampling device to solve the problems mentioned in the above background problems.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a multi-level sewage sampling device, including a mounting table, a mounting cylinder is provided on the lower surface of the mounting table, a mounting groove is provided on the side wall of the mounting cylinder, the mounting groove is threadedly connected to a sampling bottle, the sampling bottle is tilted upward, a water inlet hole is provided on the sampling bottle, the water inlet hole cross-section is trapezoidal, a sliding sleeve is provided on one side of the water inlet hole, a through hole is provided at one end of the sliding sleeve close to the water inlet hole, the through holes are several and arranged circumferentially, a first sealing plug is threadedly provided at one end of the sampling bottle, the first sealing plug is in contact with the sliding sleeve and seals the sliding sleeve, and a sealing mechanism is provided inside the sliding sleeve.

[0006] The above technical scheme is adopted, by arranging a mounting platform, a mounting tube, a mounting groove, a sampling bottle, a water inlet, a sliding sleeve, a through hole, a first sealing plug and a sealing mechanism. When in use, the mounting platform can install the mounting tube, and then the sampling bottle is threadedly connected to the mounting groove. By cross-arranging multiple sampling bottles on the mounting tube, sewage of different depths can be sampled, and then the first sealing plug seals one end of the sampling bottle close to the mounting tube. When the sampling bottle reaches the specified depth and needs to be sampled, it is only necessary to control the sealing mechanism to slide in the sliding sleeve to leak out the water inlet and the through hole. Sewage of different depths first enters the sliding sleeve through the water inlet and then enters the sampling bottle through the through hole. After sampling is completed, it is only necessary to drive the sealing mechanism to move in the sliding sleeve to re-seal the water inlet.

[0007] The utility model is further configured as follows: the sealing mechanism includes a second sealing plug, a connecting rod, a first micro cylinder and a moving rod, the second sealing plug is arranged inside the sliding sleeve, the second sealing plug is arranged to fit the cross-section of the water inlet hole, the connecting rod is arranged at one end of the second sealing plug, the connecting rod passes through the first sealing plug and extends to the inside of the mounting tube, the first micro cylinder is arranged inside the mounting tube, the moving rod is arranged on the telescopic end of the first micro cylinder, and the other end of the connecting rod is hinged to the moving rod.

[0008] The above technical solution is adopted, by setting a second sealing plug, a connecting rod, a first micro cylinder and a moving rod. When in use, first open the first micro cylinder to move the moving rod downward in the installation tube. Since the connecting rod and the moving rod are hinged, the connecting rod can drive the second sealing plug to slide in the sliding sleeve, thereby leaking out the water inlet and the through hole, thereby realizing the sampling of sewage. When the sampling is completed, it is only necessary to drive the moving rod to move upward in the sliding sleeve by the first micro cylinder, so that the second sealing plug can re-seal the water inlet. At this time, when the sampling bottle is taken out, sewage of different depths will not enter the sampling bottle, thereby avoiding contamination of the sample sewage in the sampling bottle.

[0009] The utility model is further configured as follows: a water depth sensor is arranged on some of the sampling bottles, a controller is arranged on the mounting platform, the controller is electrically connected to the water depth sensor and the first micro cylinder, a display is arranged on the controller, and the display is electrically connected to the water depth sensor.

[0010] By adopting the above technical solution, a water depth sensor, a controller and a display are set. When in use, the water depth sensor can detect the depth of the sampling bottle, and then transmit the data of the depth of the sampling bottle to the display, so that the staff can understand the depth of the sampling bottle, and then the controller can control the first micro cylinder and the water depth sensor.

[0011] The utility model is further configured as follows: a fixing cone is arranged at the lower end of the installation tube, and a supporting platform for limiting the descending distance of the moving rod is arranged at the lower end of the interior of the installation tube.

[0012] By adopting the above technical solution, a fixed cone and a support platform are set. When in use, the fixed cone is set at the lower end of the mounting tube. When the mounting tube moves downward, the fixed cone can reduce the buoyancy effect of the water surface on the mounting tube. Then the support platform can prevent the moving rod from moving too far in the mounting tube, prevent the second sealing plug from moving too far in the sliding sleeve, and avoid affecting the sampling bottle.

[0013] The utility model is further configured as follows: a limiting rod is arranged on the support platform, a limiting groove is arranged inside the moving rod, and the limiting rod is arranged inside the limiting groove.

[0014] By adopting the above technical solution, a limit rod and a limit groove are set. When in use, the limit rod is set in the limit groove. When the moving rod moves in the mounting tube, the limit rod and the limit groove are used in combination to limit the movement of the moving rod so that the moving rod can only move along the direction of the limit rod.

[0015] The utility model is further configured as follows: an installation cavity is provided inside the installation platform, a second micro cylinder is provided inside the installation cavity, the second micro cylinder is electrically connected to the controller, and a telescopic shaft of the second micro cylinder is connected to the installation tube.

[0016] By adopting the above technical solution, by setting up the installation cavity and the second micro cylinder, when in use, the installation cavity can install the second micro cylinder, and then the second micro cylinder can drive the installation tube to move, moving the sampling bottle to the corresponding depth in the sewage.

[0017] The utility model is further configured as follows: a handle is provided on the upper surface of the mounting platform to provide a fulcrum for the staff.

[0018] By adopting the above technical solution and providing a handle, the handle can provide a fulcrum for the staff when in use, so that the staff can take the installation table.

[0019] In summary, the utility model has the following beneficial effects:

[0020] By arranging a mounting platform, a mounting tube, a mounting groove, a sampling bottle, a water inlet, a sliding sleeve, a through hole, a first sealing plug and a sealing mechanism, when in use, the mounting platform can be used to mount the mounting tube, and then the sampling bottle is threadedly connected to the mounting groove; by cross-arranging a plurality of sampling bottles on the mounting tube, it is possible to sample sewage of different depths; then the first sealing plug seals one end of the sampling bottle close to the mounting tube; when the sampling bottle reaches a specified depth and needs to be sampled, it is only necessary to control the sealing mechanism to slide in the sliding sleeve to leak out the water inlet and the through hole; sewage of different depths first enters into the sliding sleeve through the water inlet, and then enters into the sampling bottle through the through hole; after sampling is completed, it is only necessary to drive the sealing mechanism to move in the sliding sleeve to re-seal the water inlet.

[0021] By setting a second sealing plug, a connecting rod, a first micro-cylinder and a moving rod, when in use, first open the first micro-cylinder to move the moving rod downward in the installation tube. Since the connecting rod and the moving rod are hinged, the connecting rod can drive the second sealing plug to slide in the sliding sleeve, thereby leaking out the water inlet and the through hole to achieve sewage sampling. After the sampling is completed, it is only necessary to drive the moving rod to move upward in the sliding sleeve by the first micro-cylinder to make the second sealing plug re-seal the water inlet. At this time, when the sampling bottle is taken out, sewage of different depths will not enter the sampling bottle, thereby avoiding contamination of the sample sewage in the sampling bottle.

[0022] Based on the above-mentioned improvements, the overall technical effect achieved by the present device is that several sampling bottles can be cross-arranged on the mounting tube, so that sewage of different depths can be sampled and processed, thereby avoiding the situation where traditional sewage sampling devices need to perform multiple sampling when sampling sewage of different depths.
