Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, and more specifically to a sewage chemical testing sampling device. Background Art

[0002] Sewage refers to water containing wastewater and pollutants from life, industry or other activities. It is wastewater generated after the use of water, and contains various organic matter, inorganic salts, microorganisms, suspended matter, dissolved matter and other pollutants. In the process of sewage treatment, it is necessary to conduct chemical testing on sewage, and the test results can reflect the pollution of sewage.

[0003] In the related art, sewage sampling is mostly done by hanging a rope on a container and then dropping the container into the sewage. However, this sampling method disturbs the sewage when stratified sampling is performed, which results in the sewage accuracy of stratified sampling being not good enough and the chemical test value having a certain deviation. Based on the above problems, we provide a sewage chemical test sampling device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a sewage chemical testing sampling device.

[0006] The utility model provides a sewage chemical testing sampling device adopts the following technical solutions:

[0007] A sewage chemical inspection sampling device comprises a sampling container; a plurality of partition plates equidistantly mounted in the sampling container for partitioning the containing cavity of the sampling container; a plurality of water inlet mechanisms sequentially mounted on the side of the sampling container for opening the sampling container to allow external sewage to enter the sampling container; each of the water inlet mechanisms corresponds one-to-one to a single containing cavity formed by the sampling container.

[0008] Preferably, the water inlet mechanism includes a transverse tube connected to the side of the sampling container, a support sleeve is fixedly connected to the interior of the transverse tube, a moving rod is slidably connected to the side of the support sleeve, one end of the moving rod is fixedly connected to a shielding cover, and the shielding cover can cover the side port of the transverse tube, a spring is inserted into the middle part of the moving rod at the position of the shielding cover and the support sleeve, a protective sleeve is fixedly connected to the side of the support sleeve, and the other end of the moving rod is inserted into the protective sleeve, an electromagnet is installed in the protective sleeve, and the electromagnet can absorb and pull the moving rod.

[0009] Preferably, a water inlet is provided at the top of the sampling container, and the water inlet passes through each partition plate in sequence. The top of the sampling container is rotatably connected with a rotating shaft, and the rotating shaft passes through each partition plate in sequence. A plurality of eccentric disks are fixedly connected to the middle of the rotating shaft relative to the water inlet, and the eccentric disks can shield the water inlet.

[0010] Preferably, a rotating sleeve is fixedly connected to the top end of the rotating shaft for rotating the rotating shaft.

[0011] Preferably, a limiting rod is slidably inserted into the top of the rotating sleeve, and two limiting grooves are provided on the top of the sampling container, and the bottom end of the limiting rod can be inserted into the limiting groove.

[0012] Preferably, an iron pad is fixedly connected to the bottom end of the sampling container to assist the sampling container to enter the sewage water body.

[0013] In summary, the utility model includes the following beneficial technical effects:

[0014] 1. Hang a rope on a sampling container and then throw the sampling container into the sewage flow. When the sampling container is in the water body, open each water inlet mechanism intermittently, thereby filling the chamber of the sampling container with sewage in turn.

Detailed implementation manners

[0023] The following further Figures 1 to 5 describes the present utility model in detail with reference to the attached

[0024] It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size for illustration, and any size is only exemplary and not limiting. In addition, the same structural elements, components or fittings that appear in more than two figures are denoted by the same reference numerals to reflect similar features.

[0025] An embodiment of the present utility model discloses a sewage chemical inspection sampling device. Referring to Figures 1 to 5 , a sewage chemical inspection sampling device includes a sampling container 1; a plurality of partition plates 2, which are equidistantly assembled in the sampling container 1 and are used to partition the cavity of the sampling container 1; a plurality of water inlet mechanisms 3, which are sequentially assembled on the side of the sampling container 1 and are used to open the sampling container 1 to allow external sewage to enter the sampling container 1; each water inlet mechanism 3 corresponds to a single cavity formed by the sampling container 1, and a U-shaped hanging plate is assembled on the top of the sampling container 1 for hanging an external rope.

[0026] Specifically, the water inlet mechanism 3 includes a transverse tube 300 connected to the side of the sampling container 1, a support sleeve 301 is fixedly connected inside the transverse tube 300, a movable rod 302 is slidably connected to the side of the support sleeve 301, one end of the movable rod 302 is fixedly connected to a shielding cover 303, and the shielding cover 303 can cover the side port of the transverse tube 300, a spring is inserted into the middle of the movable rod 302 at the position between the shielding cover 303 and the support sleeve 301, a protective sleeve 304 is fixedly connected to the side of the support sleeve 301, and the other end of the movable rod 302 is inserted into the protective sleeve 304, an electromagnet 305 is installed in the protective sleeve 304, the electromagnet 305 is powered by an external battery and controlled by a control switch, and the electromagnet 305 can absorb and pull the movable rod 302.

[0027] First, hang a rope on the sampling container 1, and then throw the sampling container 1 into the sewage flow. When the sampling container 1 is in the water body, open each water inlet mechanism 3 intermittently, thereby filling the sewage into the cavity of the sampling container 1 in turn. When the sewage is full, pull up the sampling container 1, thereby completing the stratified sampling of the sewage. Through this structural design, stratified sampling can be carried out in the sewage, and the stratification of the sewage is a single sampling, which can reduce the influence of the sewage in each stratification on each other.

[0028] The use of the water inlet mechanism 3 is that the operator turns on the circuit of the electromagnet 305, so that the electromagnet 305 has magnetic force, and then the electromagnet 305 attracts the movable rod 302, so that the movable rod 302 moves to move the shielding cover 303 to the side port of the transverse tube 300, and the channel of the transverse tube 300 is shielded. When the sampling container 1 completely enters the sewage, the circuits of each electromagnet 305 are intermittently disconnected, so that the spring pushes the shielding cover 303 to separate from the transverse tube 300, thereby taking water. After the water is taken from a single cavity, the circuit of the electromagnet 305 is turned on, so that the transverse tube 300 is shielded, thereby completing the stratified sampling of sewage.

[0029] Reference Figure 3 A water inlet 4 is provided at the top of the sampling container 1, and the water inlet 4 passes through each partition plate 2 in sequence. A rotating shaft 5 is rotatably connected to the top of the sampling container 1, and the rotating shaft 5 passes through each partition plate 2 in sequence. A plurality of eccentric disks 6 are fixedly connected to the middle of the rotating shaft 5 relative to the water inlet 4, and the eccentric disk 6 can shield the water inlet 4. When stratified sampling is not required, the operator can rotate the rotating shaft 5 to separate each eccentric disk 6 from the corresponding water inlet 4, thereby connecting each cavity, and then the operator throws the sampling container 1 into the sewage to take samples.

[0030] Reference Figure 5 A rotating sleeve 7 is fixedly connected to the top end of the rotating shaft 5 for rotating the rotating shaft 5 .

[0031] Specifically, a limiting rod 8 is slidably inserted into the top of the rotating sleeve 7, and two limiting grooves 9 are opened on the top of the sampling container 1. The bottom end of the limiting rod 8 can be inserted into the limiting groove 9. After the rotating shaft 5 rotates, the limiting rod 8 can be pushed so that the limiting rod 8 is inserted into the corresponding limiting groove 9, thereby completing the limitation of the position of the rotating shaft 5.

[0032] Reference Figure 1 and Figure 2 An iron pad 10 is fixedly connected to the bottom of the sampling container 1 to assist the sampling container 1 to enter the sewage body.

The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0034] The implementation principle of a sewage chemical inspection sampling device according to an embodiment of the utility model is as follows: first, a rope is hung on a sampling container 1, and then the sampling container 1 is thrown into the sewage flow. When the sampling container 1 is in the water body, each water inlet mechanism 3 is intermittently opened to fill the sewage into the cavity of the sampling container 1 in turn. When the sewage is full, the sampling container 1 is pulled up to complete the stratified sampling of the sewage.

[0035] For the use of the water inlet mechanism 3, the operator turns on the circuit of the electromagnet 305 so that the electromagnet 305 has magnetic force, and then the electromagnet 305 attracts the movable rod 302, so that the movable rod 302 moves to move the shielding cover 303 to the side port of the transverse tube 300, and the channel of the transverse tube 300 is shielded. When the sampling container 1 completely enters the sewage, the circuits of each electromagnet 305 are intermittently disconnected, so that the spring pushes the shielding cover 303 to separate from the transverse tube 300, thereby taking water. After the water is taken from a single cavity, the circuit of the electromagnet 305 is turned on, so that the transverse tube 300 is shielded, thereby completing the stratified sampling of sewage.
