Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to a sampling device for urban sewage treatment. Background Technique

[0002] Urban sewage treatment refers to measures taken to change the nature of sewage so that it does not harm the environmental water area. During the sewage treatment process, it is necessary to sample and detect it to determine the current sewage nature and subsequent treatment plans;

[0003] In the prior art, a patent with the publication number of CN216816132U discloses a sewage sampling device for urban sewage treatment, including a protective cylinder. A sampling cylinder is provided below the protective cylinder. Water outlet grooves are opened at the left parts of the upper ends of the sampling cylinder and the protective cylinder, and air exchange grooves are opened at the right parts of the upper ends of the sampling cylinder and the protective cylinder. A water outlet pipe is fixedly provided on the water outlet groove on the left. Symmetrically arranged positioning grooves are opened on the inner wall of the protective cylinder. During the sampling process, the air pressure inside the device can be kept stable through the air exchange groove. At the same time, through the cooperation of the positioning block and the positioning groove, the two water outlet grooves and the air exchange groove can coincide after sampling to ensure the pouring out of the sewage after sampling. The design of the utility model is novel and reasonable, which can avoid sampling personnel from contacting the sewage, prevent the sampler from being contaminated by the sewage, and the sampling is relatively clean;

[0004] In the above prior art, after sewage sampling, the sampling cylinder is exposed outside, and there is still a possibility that the operator contacts the sewage adhered to the surface of the sampling cylinder, so the practicability is poor. Moreover, in the above prior art, after sewage sampling, the sampling cylinder and the water outlet pipe are in a communicating state, resulting in that during the sampling process, when the sampling cylinder shakes or tilts, the sewage in the sampling cylinder will flow out through the water outlet pipe. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sampling device for urban sewage treatment to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sampling device for urban sewage treatment, including:

[0008] A protective cylinder, on the surface of which a water outlet is fixedly provided, and a guiding groove is opened on the inner wall of the protective cylinder;

[0009] A sampling cylinder, which is slidably arranged inside the protective cylinder. A sampling chamber is arranged inside the sampling cylinder. A water inlet is opened on the surface of the sampling cylinder. An auxiliary push rod is fixedly connected above the sampling cylinder;

[0010] An upper baffle, which is slidably arranged inside the protective cylinder, and a lower baffle is arranged between the upper baffle and the sampling cylinder.

[0011] Preferably, a finger buckle is fixedly installed at the top end of the protective cylinder. A main push rod telescopic hole is opened inside the finger buckle, and the main push rod telescopic hole communicates with the inside of the protective cylinder.

[0012] Preferably, two groups of water outlets are opened, and the two groups of water outlets are symmetrically arranged on the side surface of the protective cylinder.

[0013] Preferably, the sampling cylinder is arranged below the water outlet, the water inlet is communicated with the sampling bin, and the water inlet is arranged above the sampling bin.

[0014] Preferably, one end of the auxiliary push rod away from the sampling cylinder is fixedly connected with a main push rod. The diameter of the main push rod is larger than that of the auxiliary push rod. The main push rod is slidably inserted into the main push rod telescopic hole, and a pressing plate is fixedly installed at one end of the main push rod away from the auxiliary push rod.

[0015] Preferably, the upper baffle is arranged above the sampling cylinder. A first auxiliary push rod telescopic hole is opened on the surface of the upper baffle, and the upper baffle is slidably sleeved on the surface of the auxiliary push rod through the first auxiliary push rod telescopic hole.

[0016] Preferably, the lower baffle is arranged between the upper baffle and the sampling cylinder. A second auxiliary push rod telescopic hole is opened on the surface of the lower baffle, and the lower baffle is slidably sleeved on the surface of the auxiliary push rod through the second auxiliary push rod telescopic hole. A guide block is fixedly arranged on the surface of the lower baffle, and the guide block is slidably arranged inside the guide groove. A compression spring is arranged between the lower baffle and the upper baffle.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] 1. By arranging a telescopic sampling cylinder inside the protective cylinder, when sewage enters the sampling bin, the sampling cylinder retracts into the protective cylinder, so that the protective cylinder covers the sampling cylinder, avoiding the operator from contacting the sewage adhered to the surface of the sampling cylinder.

[0019] 2. By arranging a water inlet, during the sampling process, sewage enters the sampling bin through the water inlet. Since the caliber of the water inlet is small, it can filter large-particle impurities in the sewage. And when the sampling cylinder retracts into the protective cylinder, the side wall of the protective cylinder will brush the surface of the sampling cylinder, so as to scrape off the impurities adhered to the entrance of the water inlet.

[0020] 3. By opening the water outlet above the sampling cylinder, the side wall of the protective cylinder blocks the water inlet, avoiding the problem of sewage spilling during the sampling process. And by symmetrically arranging two groups of water outlets, the sewage can be poured out from both sides, improving the convenience of operation. At the same time, when the sewage is poured out through one water outlet, the other water outlet plays a role in ventilation, avoiding the problem that the sewage inside the sampling bin cannot be poured out due to air pressure reasons.

[0031] Please refer to the attached Figure 1 to the attached Figure 4 As shown, the present utility model provides a sampling device for urban sewage treatment, including:

[0032] A protective cylinder 1, on the surface of the protective cylinder 1, there is a water outlet 11 fixedly arranged. There are two groups of water outlets 11, and the two groups of water outlets 11 are symmetrically arranged on the side surface of the protective cylinder 1. At the top end of the protective cylinder 1, a finger buckle 12 is fixedly installed. Inside the finger buckle 12, there is a main push rod telescopic hole 13, and the main push rod telescopic hole 13 is communicated with the inside of the protective cylinder 1. On the inner wall of the protective cylinder 1, there is a guide groove 14;

[0033] A sampling cylinder 2, the sampling cylinder 2 is slidably arranged inside the protective cylinder 1. Inside the sampling cylinder 2, there is a sampling chamber 21. On the surface of the sampling cylinder 2, there is a water inlet 22. The sampling cylinder 2 is arranged below the water outlet 11, and the water inlet 22 is communicated with the sampling chamber 21. The water inlet 22 is arranged above the sampling chamber 21. Above the sampling cylinder 2, there is an auxiliary push rod 32 fixedly connected. One end of the auxiliary push rod 32 away from the sampling cylinder 2 is fixedly connected with a main push rod 3. The main push rod 3 is slidably inserted into the inside of the main push rod telescopic hole 13. One end of the main push rod 3 away from the auxiliary push rod 32 is fixedly installed with a pressing plate 31;

[0034] The upper baffle plate 4 is slidably arranged inside the protection cylinder 1. The upper baffle plate 4 is arranged above the sampling cylinder 2. A first auxiliary push rod telescopic hole 41 is formed on the surface of the upper baffle plate 4. The upper baffle plate 4 is slidably sleeved on the surface of the auxiliary push rod 32 through the first auxiliary push rod telescopic hole 41. A lower baffle plate 5 is arranged between the upper baffle plate 4 and the sampling cylinder 2. The lower baffle plate 5 is arranged between the upper baffle plate 4 and the sampling cylinder 2. A second auxiliary push rod telescopic hole 51 is formed on the surface of the lower baffle plate 5. The lower baffle plate 5 is slidably sleeved on the surface of the auxiliary push rod 32 through the second auxiliary push rod telescopic hole 51. A guide block 52 is fixedly arranged on the surface of the lower baffle plate 5. The guide block 52 is slidably arranged inside the guide groove 14. A compression spring 6 is arranged between the lower baffle plate 5 and the upper baffle plate 4. Embodiment

[0035] When the sampling device for urban sewage treatment proposed by the present utility model is in use, the finger is buckled into the finger buckle 12, and then the pressing plate 31 is pushed. The pressing plate 31 drives the sampling cylinder 2 to extend out of the protection cylinder 1 through the main push rod 3 and the auxiliary push rod 32. At the same time, the main push rod 3 squeezes the upper baffle plate 4 towards the direction close to the lower baffle plate 5. The sampling cylinder 2 is inserted into the sewage to be sampled, and the sampling cylinder 2 is controlled to shake in the sewage, so that the sewage enters into the sampling chamber 21 through the water inlet 22. Then, the pressing on the pressing plate 31 is released. At this time, under the resilience of the compression spring 6, the upper baffle plate 4 pushes the main push rod 3 to move upwards, thereby driving the sampling cylinder 2 to retract into the protection cylinder 1, and the protection cylinder 1 covers the sampling cylinder 2;

[0036] By arranging the telescopic sampling cylinder 2 inside the protection cylinder 1, after the sewage enters into the sampling chamber 21, the sampling cylinder 2 retracts into the protection cylinder 1, so that the protection cylinder 1 covers the sampling cylinder 2, avoiding the operator from contacting the sewage adhered to the surface of the sampling cylinder 2;

[0037] By arranging the water inlet 22, during the sampling process, the sewage enters into the sampling chamber 21 through the water inlet 22. Since the caliber of the water inlet 22 is small, it plays a role in filtering large particle impurities in the sewage. And when the sampling cylinder 2 retracts into the protection cylinder 1, the side wall of the protection cylinder 1 will brush the surface of the sampling cylinder 2, thereby scraping off the impurities adhered to the entrance of the water inlet 22. Embodiment

[0038] On the basis of the first embodiment, by opening the water outlet 11 above the sampling cylinder 2, the side wall of the protective cylinder 1 seals the water inlet 22. When it is necessary to take out the sewage inside the sampling chamber 21, by pulling the pressing plate 31 to drive the sampling cylinder 2 to move in the direction close to the upper baffle 4, the lower baffle 5 is extruded during the movement of the sampling cylinder 2. When the water inlet 22 is aligned with the water outlet 11, the protective cylinder 1 is tilted, so that the sewage inside the sampling chamber 21 is poured out through the water outlet 11, thus avoiding the problem of sewage spilling during the sampling process. And by symmetrically arranging two groups of water outlets 11, the sewage can be poured out from both sides, improving the convenience of operation. At the same time, when the sewage is poured out through the water outlet 11 on one side, the water outlet 11 on the other side plays a role in ventilation, avoiding the situation that the sewage inside the sampling chamber 21 cannot be poured out due to air pressure reasons.

[0039] Working principle: The treatment of urban sewage refers to the measures taken to change the nature of sewage so that it does not cause harm to the environmental water area. A sampling device for urban sewage treatment proposed by the present utility model, when in use, insert the finger into the finger buckle 12, and then push the pressing plate 31. The pressing plate 31 drives the sampling cylinder 2 to extend from the inside of the protective cylinder 1 through the main push rod 3 and the auxiliary push rod 32. At the same time, the main push rod 3 extrudes the upper baffle 4 in the direction close to the lower baffle 5, inserts the sampling cylinder 2 into the sewage to be sampled, and controls the sampling cylinder 2 to shake in the sewage, so that the sewage enters the inside of the sampling chamber 21 through the water inlet 22. Then release the pressing on the pressing plate 31. At this time, under the resilience of the compression spring 6, the upper baffle 4 pushes the main push rod 3 to move upward, thereby driving the sampling cylinder 2 to retract into the inside of the protective cylinder 1, covering the sampling cylinder 2 through the protective cylinder 1. When it is necessary to take out the sewage inside the sampling chamber 21, by pulling the pressing plate 31 to drive the sampling cylinder 2 to move in the direction close to the upper baffle 4, the lower baffle 5 is extruded during the movement of the sampling cylinder 2. When the water inlet 22 is aligned with the water outlet 11, the protective cylinder 1 is tilted, so that the sewage inside the sampling chamber 21 is poured out through the water outlet 11.
