Description

Technical Field

[0001] This utility model relates to the field of water quality sampling technology, and in particular to a water quality sampling device for harmless sewage treatment. Background Technology

[0002] After wastewater undergoes harmless treatment, water quality monitoring of the treated water is necessary. Currently, a common water sampler is used for sampling. This sampler is a barrel-shaped container with a rope attached to its handle. To use it, one hand holds the rope while the other throws the container to collect a sample. While this sampler is simple in structure, it can only capture water from the surface of the pool and cannot easily sample water below the surface. To address this issue, our company's technicians designed a wastewater harmless treatment water quality sampling device as described in this application. Utility Model Content

[0003] The purpose of this invention is to provide a water quality sampling device for the harmless treatment of sewage, which can conveniently sample water at a certain depth below the water surface.

[0004] To achieve the above objectives, this utility model provides a wastewater harmless treatment water quality sampling device, including a tank body with a sampling hole at the bottom, a sliding rod, and a sliding plug. A pull ring is installed at the upper end of the sliding rod, and the lower end of the sliding rod is slidably inserted into the tank body from the top. The sliding plug is slidably installed at the bottom of the tank body. A lower through hole and an upper through hole are provided at the upper end of the sliding rod, and the lower through hole and the upper through hole communicate internally. The frictional force between the sliding rod and the tank body is greater than the weight of the tank body and the sliding plug. In use: when the sliding rod moves downward to the lower limit, the lower end of the sliding rod abuts against the sliding plug, causing the sliding plug to close the sampling hole. At this time, both the lower and upper through holes are located inside the tank body. When the sliding rod moves upward to the upper limit, the sliding rod disengages from the sliding plug. At this time, the lower through hole is located inside the tank body, and the upper through hole is located outside the tank body.

[0005] The top of the tank is provided with an extension ring, and an annular groove is provided inside the extension ring. A sealing ring is installed in the annular groove. The frictional force between the sliding rod and the sealing ring is greater than the weight of the tank and the sliding plug.

[0006] A guide frame is also fixedly connected inside the tank. The guide frame includes a guide ring and a support rod. The guide ring is slidably fitted outside the sliding rod, and the guide ring is fixedly connected to the inner wall of the tank through the support rod.

[0007] The sliding rod includes a vent pipe, a pull ring located at the top of the vent pipe, a lower through hole and an upper through hole provided on the vent pipe, and a limit ring provided on the vent pipe between the lower through hole and the upper through hole, the limit ring being located inside the tank.

[0008] The sliding rod also includes an extension rod, which is connected to the lower end of the vent pipe.

[0009] The sliding plug includes a sealing cap, a connecting rod, and a limiting part. The connecting rod is fixed between the sealing cap and the limiting part. The sealing cap is located in the tank body. A sliding hole is provided at the bottom of the tank body. The sampling hole is located outside the sliding hole. The connecting rod slides in the sliding hole. When the sealing cap is in contact with the bottom wall of the tank body, the sealing cap will close the sampling hole.

[0010] A sealing gasket is installed at the bottom of the closure.

[0011] The bottom of the tank has a conical structure.

[0012] Compared with the prior art, this utility model has the following technical effects:

[0013] 1. The tank of this utility model is used to hold sampled water, and the pull ring is used to connect with the pull line. As shown in the figure, when the sliding rod moves down to the lower limit, the lower end of the sliding rod abuts against the sliding plug so that the sliding plug closes the sampling hole. At this time, both the lower through hole and the upper through hole are located in the tank. In this state, it is convenient to put the sampling device below the water surface. During the placement process, since the friction between the sliding rod and the tank is greater than the weight of the tank and the sliding plug, the sliding rod will not slide and water will not enter the tank. Once the sampling device is below the water surface, quickly pull up the pull line. Due to inertia, the sampling device will remain stationary. The pulling force of the pull line exceeds the friction between the sliding rod and the tank body, causing the sliding rod to move to its upper limit and disengage from the sliding plug. At this point, the lower through-hole is inside the tank, and the upper through-hole is outside, connecting the tank to the water. Simultaneously, due to the height difference between the bottom sampling hole and the upper through-hole, the water pressure is different. Furthermore, because the sliding rod is disengaged from the sliding plug, water will push up the sliding plug from the sampling hole and enter the tank body. This invention allows for convenient sampling of water at a certain depth below the water surface.

[0014] 2. After taking water using this utility model, place the sampling device into the container. When the limiting part contacts the bottom of the container, as the sampling device moves down, the limiting part will lift the sealing cover. At this time, the sampling hole is opened, which facilitates the water in the tank to flow out. Attached Figure Description

[0029] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0030] Example 1:

[0031] Please see Figure 1-7 A wastewater harmless treatment water quality sampling device includes a tank 10, a sampling hole 11 at the bottom of the tank 10, a sliding rod 20 and a sliding plug 40. The upper end of the sliding rod 20 is equipped with a pull ring 26, and the lower end of the sliding rod 20 is slidably inserted into the tank 10 from the top. The sliding plug 40 is slidably installed at the bottom of the tank 10. The upper end of the sliding rod 20 is provided with a lower through hole 23 and an upper through hole 24, which are internally connected. The friction between the sliding rod 20 and the tank 10 is greater than the weight of the tank 10 and the sliding plug 40.

[0032] Tank 10 is used to hold the sampled water, and pull ring 26 is used to connect to pull line 50. See below. Figure 1 When the sliding rod 20 moves downward to the lower limit, the lower end of the sliding rod 20 abuts against the sliding plug 40, so that the sliding plug 40 closes the sampling hole 11. At this time, both the lower through hole 23 and the upper through hole 24 are located inside the tank 10. In this state, it is convenient to put the sampling device below the water surface. During the placement process, since the friction between the sliding rod 20 and the tank 10 is greater than the weight of the tank 10 and the sliding plug 40, the sliding rod 20 will not slide, and water will not enter the tank 10.

[0033] It should be noted that, in order for the sampling device of this application to be deployed below the water surface, the weight of the sampling device needs to be greater than its buoyancy.

[0034] Once the sampling device is below the water surface, quickly pull up the pull line 50. Due to inertia, the sampling device will remain stationary. The pulling force of pulling up the pull line 50 is greater than the frictional force between the sliding rod 20 and the tank body 10. At this point, the sliding rod 20 moves upward to its upper limit position. (See below) Figure 4 When the sliding rod 20 disengages from the sliding plug 40, the lower through hole 23 is located inside the tank 10 and the upper through hole 24 is located outside the tank 10, allowing the inside of the tank 10 to communicate with the water. At the same time, due to the height difference between the bottom sampling hole 11 and the upper through hole 24, the water pressure is different. Also, because the sliding rod 20 disengages from the sliding plug 40, water will push up the sliding plug 40 from the sampling hole 11 and enter the tank 10.

[0035] It should be noted that, in order to facilitate the water's ability to lift the sliding plug 40, the weight of the sliding plug 40 is slightly greater than its buoyancy. The sliding plug 40 can be made of plastic.

[0036] Once no more bubbles emerge from the water surface, continue pulling the line 50 upwards. As the sampling device approaches the water surface, the water in tank 10 tends to flow out of the sampling hole 11. At this point, under the combined action of the gravity of the sliding plug 40 and the water flow within tank 10, see... Figure 6 The sliding plug 40 moves down to close the sampling hole 11, thereby extracting the water.

[0037] In this embodiment, see Figure 1 An extension ring 12 is provided at the top of the tank body 10, and an annular groove 13 is provided inside the extension ring 12. A sealing ring 14 is installed in the annular groove 13. The frictional force between the sliding rod 20 and the sealing ring 14 is greater than the weight of the tank body 10 and the sliding plug 40. Through the above structure, the sliding rod 20 and the sealing ring 14 can slide together, and a sealing effect can be achieved. At the same time, since the inner hole of the sealing ring 14 is elastic, the frictional force between the sliding rod 20 and the sealing ring 14 can be guaranteed.

[0038] In this embodiment, the sealing ring 14 is a skeleton oil seal, and a spring is installed inside the skeleton oil seal, which enables the inner hole of the sealing ring 14 to have a good sliding sealing effect and also provides friction.

[0039] Example 2:

[0040] Based on Example 1, see Figure 1 , 2 A guide frame 30 is also fixedly connected inside the tank body 10. The guide frame 30 includes a guide ring 31 and a support rod 32. The guide ring 31 is slidably fitted outside the sliding rod 20, and the guide ring 31 is fixedly connected to the inner wall of the tank body 10 through the support rod 32. The above structure ensures the directional sliding of the sliding rod 20.

[0041] Example 3:

[0042] Based on Example 1 or 2, see Figure 1 , 3 The sliding rod 20 includes a vent pipe 21, a pull ring 26 located at the top of the vent pipe 21, a lower through hole 23 and an upper through hole 24 provided on the vent pipe 21, and a limit ring 22 provided on the vent pipe 21 between the lower through hole 23 and the upper through hole 24, the limit ring 22 being located inside the tank body 10. The limit ring 22 is used to limit the vent pipe 21 to prevent it from detaching from the tank body 10 when the pull line 50 is lifted.

[0043] Furthermore, the sliding rod 20 also includes an extension rod 25, which is connected to the lower end of the vent pipe 21. In this embodiment, the guide ring 31 is slidably fitted onto the outside of the extension rod 25.

[0044] Example 4:

[0045] Based on Example 1, 2, or 3, see [link to example]. Figure 1 , 5 The sliding plug 40 includes a sealing cap 41, a connecting rod 42, and a limiting part 43. The connecting rod 42 is fixed between the sealing cap 41 and the limiting part 43. The sealing cap 41 is located in the tank body 10. A sliding hole is provided at the bottom of the tank body 10, and the sampling hole 11 is located outside the sliding hole. The connecting rod 42 slides in the sliding hole. When the sealing cap 41 is in contact with the bottom wall of the tank body 10, the sealing cap 41 closes the sampling hole 11. The sealing cap 41 is used to close the sampling hole 11, and the limiting part 43 is used to limit the sealing cap 41 to prevent the connecting rod 42 from falling out of the sliding hole.

[0046] Simultaneously, through the above structure, see [link / reference] Figure 7 After water is collected, the sampling device is placed in the container 60. When the limiting part 43 contacts the bottom of the container 60, the limiting part 43 lifts the sealing cover 41 as the sampling device moves down. At this time, the sampling hole 11 is opened, and the water in the tank 10 flows out into the container 60.

[0047] Furthermore, a sealing gasket 44 is provided at the bottom of the sealing cover 41. The sealing gasket 44 is made of rubber to improve the sealing effect. During installation, the annular sealing gasket 44 is adhered to the bottom of the sealing cover 41, and the sealing gasket 44 is located outside the sampling hole 11.

[0048] Example 5:

[0049] Based on Example 1, 2, 3, or 4, see [link to example]. Figure 1 The bottom of the tank 10 has a conical structure 15, and the bottom area of ​​the tank 10 is smaller, which makes it easier for the bottom of the tank 10 to break through and enter below the water surface.

[0050] The working principle or operation process of this utility model is as follows:

[0051] See Figure 1 During sampling, the sliding rod 20 is first moved downward to the lower limit position, so that the lower end of the extension rod 25 abuts against the sliding plug 40. The sliding plug 40 closes the sampling hole 11. At this time, both the lower through hole 23 and the upper through hole 24 are located inside the tank 10. In this state, it is convenient to put the sampling device below the water surface. During the placement process, since the friction between the sliding rod 20 and the tank 10 is greater than the weight of the tank 10 and the sliding plug 40, the sliding rod 20 will not slide, and water will not enter the tank 10.

[0052] Once the sampling device is below the water surface, quickly pull up the pull line 50. Due to inertia, the sampling device will remain stationary. The pulling force of pulling up the pull line 50 is greater than the frictional force between the sliding rod 20 and the tank body 10. At this point, the sliding rod 20 moves upward to its upper limit position. (See below) Figure 4 When the sliding rod 20 disengages from the sliding plug 40, the lower through hole 23 is located inside the tank 10, and the upper through hole 24 is located outside the tank 10. The inside of the tank 10 is connected to the water. At the same time, due to the height difference between the bottom sampling hole 11 and the upper through hole 24, the water pressure is different. Also, because the sliding rod 20 disengages from the sliding plug 40, water will push up the sliding plug 40 from the sampling hole 11 and enter the tank 10.

[0053] Once no more bubbles emerge from the water surface, continue pulling the line 50 upwards. As the sampling device approaches the water surface, the water in tank 10 tends to flow out of the sampling hole 11. At this point, under the combined action of the gravity of the sliding plug 40 and the water flow within tank 10, see... Figure 6 The sliding plug 40 moves down to close the sampling hole 11, thereby extracting the water.

[0054] After taking water, see Figure 7When the sampling device is placed in the container 60, and the limiting part 43 contacts the bottom of the container 60, the limiting part 43 lifts the sealing cover 41 as the sampling device moves down. At this time, the sampling hole 11 is opened, and the water in the tank 10 flows out into the container 60.
