Description

Technical Field

[0001] The utility model relates to the technical field of sewage extraction, in particular to a sewage extraction and storage device for environmental monitoring. Background Art

[0002] A sewage extraction and storage device for environmental monitoring (publication number: CN219957034U) disclosed on the Chinese patent website solves the problem that the traditional sewage extraction equipment sampling method is relatively simple. It directly uses a jar to collect water from the target sewage source, then covers it with a lid and takes it back for testing. This device can only collect water on the surface of the sewage source and cannot extract water at a certain depth. However, the following problems still exist:

[0003] In actual use, not only does it need to push the sampling tank deep into the water body at a certain depth, but it also needs to control the tank to only collect water within the depth range. Most of the existing underwater sampling equipment uses complex electrical equipment such as sensors for underwater control. The sensor control system usually requires complex electronic and mechanical structures, which increases the complexity and cost of the system, and the maintenance cost is high. Due to the complexity of mechanical equipment such as sensors, the maintenance and repair costs may be high, and regular maintenance is required to ensure normal operation, which is inconvenient to use. Utility Model Content

[0004] Based on the technical problem that the existing sewage extraction and storage device for environmental monitoring has a complex structure, the utility model proposes a sewage extraction and storage device for environmental monitoring.

[0005] The utility model proposes a sewage extraction and storage device for environmental monitoring, which comprises a frame and a lifting assembly. The lifting assembly is installed on the inner wall of the frame. A sampling mechanism is installed on the lifting end of the lifting assembly. The sampling mechanism comprises a sampling barrel. The sampling barrel is in the shape of a cylinder with an opening on the lower surface. The inner bottom wall of the sampling barrel is concave. A weight-increasing groove is provided inside the side wall of the sampling barrel. The inner bottom wall of the sampling barrel is concave, so that the sample can be retained easily.

[0006] Preferably, an expansion groove is provided on the inner wall of the lower end of the sampling barrel, the upper end opening of the expansion groove is connected to the interior of the weight-increasing groove, the end of the expansion groove is connected to the inner wall of the lower opening of the sampling barrel, the inner wall of the expansion groove is fixedly connected with an expansion tape, and the inner wall of the lower opening of the sampling barrel is fixedly connected with a rubber gasket.

[0007] Through the above technical scheme, the expansion tape expands when it encounters water and squeezes the rubber gasket, so that the rubber gasket bulges inward. A metal mesh can also be fixedly installed on the other side of the expansion tape through the inner wall of the expansion groove, so that water can contact the expansion tape and the expansion tape can squeeze the rubber gasket.

[0008] Preferably, a sealing plug is slidably inserted into the lower opening of the sampling tube, a slot is provided on the side wall surface of the sealing plug, and a counterweight is fixedly connected to the lower surface of the sealing plug.

[0009] Through the above technical scheme, a groove is opened on the surface of the sealing plug, so that the rubber gasket can be squeezed into the groove after being squeezed, and the diameter of the sealing plug is set to be smaller than the inner diameter of the opening of the sampling tube to avoid friction between the surface of the sealing plug and the opening surface of the sampling tube.

[0010] Preferably, the lower surface of the counterweight block is fixedly connected to a bottom plate, and the upper surface edge of the bottom plate is fixedly connected to a connecting rod.

[0011] Through the above technical solution, the weight block is used to increase the gravity of the sampling mechanism, thereby facilitating the sampling mechanism to sink in the water body.

[0012] Preferably, a sliding block is slidably sleeved on the surface of the connecting rod, a side wall surface of the sliding block is fixedly connected to an outer side wall surface of the sampling tube, and a top plate is fixedly connected to the upper surface of the connecting rod.

[0013] Through the above technical solution, the sampling tube is movably installed on the surface of the connecting rod through the slider, so that the sampling tube can be easily lifted and lowered on the surface of the connecting rod.

[0014] Preferably, the sampling tube is located between the counterweight block and the top plate, and the upper surface of the top plate is fixedly connected to the hoisting end of the lifting assembly.

[0015] Through the above technical solution, the top plate is used to limit the rising height of the sampling tube, thereby preventing the sampling tube from being completely separated.

[0016] The beneficial effects of the present invention are:

[0017] The sampling mechanism is installed at the lower end of the lifting assembly, and the sampling mechanism does not have any electrical equipment. When the sampling mechanism sinks into the water body, the buoyancy of the sampling tube increases with the increase of depth, which eventually causes the sampling tube to separate from the sealing cover, and then the water sample is taken. By filling different amounts of fillers into the weight-increasing groove, the gravity of the sampling tube is changed, and the depth of the water body when the sampling tube is separated from the sealing cover is adjusted, so that the sampling tube is separated from the sealing cover at a specified depth, and sampling is performed, so that the sampling mechanism has the characteristic of sampling water bodies at a specified depth.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 A sewage extraction and storage device for environmental monitoring includes a frame 1 and a lifting assembly 2. The lifting assembly 2 is installed on the inner wall of the frame 1. A sampling mechanism is installed on the lifting end of the lifting assembly 2. The sampling mechanism includes a sampling barrel 3. The sampling barrel 3 is cylindrical with an opening on the lower surface. The inner bottom wall of the sampling barrel 3 is concave. A weight-increasing groove 31 is opened inside the side wall of the sampling barrel 3. The inner bottom wall of the sampling barrel 3 is concave, so that the sample can be retained easily.

[0025] In order to fix the sealing cover, an expansion groove is provided on the inner wall of the lower end of the sampling tube 3, the upper end opening of the expansion groove is connected to the interior of the weight-increasing groove 31, the end of the expansion groove is connected to the inner wall of the lower end opening of the sampling tube 3, the inner wall of the expansion groove is fixedly connected with an expansion tape 32, and the inner wall of the lower end opening of the sampling tube 3 is fixedly connected with a rubber gasket 33. The expansion tape 32 expands when it encounters water and squeezes the rubber gasket 33, so that the rubber gasket 33 protrudes inward, and a metal mesh can be fixedly installed on the other side of the expansion tape 32 through the inner wall of the expansion groove, so that water can contact the expansion tape 32 and the expansion tape 32 can squeeze the rubber gasket 33.

[0026] In order to close the lower opening of the sampling tube 3, a sealing plug 34 is slidably inserted into the lower opening of the sampling tube 3, a groove is provided on the side wall surface of the sealing plug 34, and a counterweight 35 is fixedly connected to the lower surface of the sealing plug 34. The groove is provided on the surface of the sealing plug 34 to facilitate the rubber gasket 33 to be squeezed into the groove after being squeezed, and the diameter of the sealing plug 34 is set to be smaller than the inner diameter of the opening of the sampling tube 3 to avoid friction between the surface of the sealing plug 34 and the opening surface of the sampling tube 3. The lower surface of the counterweight 35 is fixedly connected to a bottom plate 36, and the upper surface edge of the bottom plate 36 is fixedly connected to a connecting rod 37. The counterweight 35 is used to increase the gravity of the sampling mechanism, thereby facilitating the sampling mechanism to sink in the water body.

[0027] By installing a sampling mechanism at the lower end of the lifting assembly 2, utilizing the closure between the sampling tube 3 and the sealing cover in the sampling mechanism, and when sinking into the water body, the buoyancy of the sampling tube 3 increases with the increase in depth, which eventually causes the sampling tube 3 to be separated from the sealing cover, and then water samples are collected. By filling different amounts of fillers into the weight-increasing groove 31, the gravity of the sampling tube 3 is changed, and the depth of the water body when the sampling tube 3 is separated from the sealing cover is adjusted, so that the sampling tube 3 is separated from the sealing cover at a specified depth, and sampling is performed, so that the sampling mechanism has the characteristic of sampling water bodies at a specified depth.

[0028] A slider 38 is slidably sleeved on the surface of the connecting rod 37, and the side wall surface of the slider 38 is fixedly connected to the outer wall surface of the sampling tube 3. The upper surface of the connecting rod 37 is fixedly connected to the top plate 39. The sampling tube 3 is movably installed on the surface of the connecting rod 37 through the slider 38, so that the sampling tube 3 can be lifted and lowered on the surface of the connecting rod 37. The sampling tube 3 is located between the counterweight block 35 and the top plate 39. The upper surface of the top plate 39 is fixedly connected to the lifting end of the lifting assembly 2. The top plate 39 is used to limit the rising height of the sampling tube 3, so as to prevent the sampling tube 3 from completely detaching.

[0029] Working principle:

[0030] When in use, a proper amount of weight is added into the weight-added groove 31 according to the sampling depth, and then the sampling tube 3 is dropped from the surface of the connecting rod 37 so that the lower end opening of the sampling tube 3 is blocked by the sealing cover, and then the entire sampling mechanism is sunk into the water body through the lifting assembly 2;

[0031] When the sampling tube 3 is in shallow water, the gravity of the sampling tube 3 overcomes the buoyancy, so that the sampling tube 3 is squeezed against the surface of the sealing plug 34 and the heavy object, and the water cannot enter the sampling tube 3. When the water is in deep water, the buoyancy of the sampling tube 3 increases, the sampling tube 3 rises on the surface of the connecting rod 37, the sampling tube 3 is separated from the sealing plug 34, the water sample enters the sampling tube 3 and enters the depression at the bottom of the sampling tube 3, the gravity of the sampling tube 3 increases, and it is closed with the sealing plug 34 again, part of the water sample contacts the expansion tape 32 through the expansion groove, the expansion tape 32 expands and squeezes the rubber gasket 33, the rubber gasket 33 is stuck in the groove on the surface of the sealing plug 34 to be closed, and then the sampling mechanism is lifted by the lifting assembly 2.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
