Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction sampling technology, specifically a sampling device for water conservancy engineering construction. Background Technology

[0002] A sampling device for water conservancy engineering construction is a specialized device or system designed for collecting and analyzing water, soil, and other samples at the construction site of water conservancy projects. This device can accurately acquire samples at specific depths or locations for subsequent testing and analysis, thereby ensuring project quality and safety.

[0003] This device typically consists of a sampler (such as a sampling tube or bottle), a positioning device, a data transmission and recording system, and possibly automated analytical instruments. These components work together to ensure effective sample collection, precise positioning, and accurate data recording and transmission.

[0004] During water sampling, the water is often affected by various impurities in the water. The water intake is easily blocked, making sampling difficult. Moreover, a large amount of debris carried by impurities is easily drawn into the sampling tube, resulting in a decline in sampling quality. Utility Model Content

[0005] The purpose of this invention is to provide a sampling device for water conservancy engineering construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for water conservancy engineering construction, comprising a sampling box, a floating ring fixedly connected to the outside of the sampling box and a sampling tube disposed on the lower side of the sampling box, wherein a filtration mechanism is disposed inside the sampling box and a dredging mechanism is disposed on the lower side of the filtration mechanism.

[0007] The unblocking mechanism includes an oscillation component and a filtration component. The oscillation component is located outside the filtration component. The filtration mechanism includes a diversion box, which is fixedly connected to the inner wall of the sampling tube. A sampling motor is fixedly connected inside the diversion box. A partition is fixedly connected inside the sampling box. A turbo fan I and a turbo fan II are fixedly connected to the output end of the sampling motor.

An opening is opened on the annular pipe. A connecting pipe is connected to the upper end of the water tank. The connecting pipe is connected to the space below the partition.

[0008] Preferably, the water tank is connected to the outside of the annular pipe through a water pipe, an annular pipe, and an opening.

[0009] Preferably, the sampling motor is installed inside the diversion box, and the water flows through the outside of the sampling motor into the space above the partition for later use.

[0010] Preferably, the water pipe is made of a rigid material and is used to support the water tank.

[0011] Preferably, the oscillation assembly includes a waterproof housing and an oscillation motor.

[0013] Preferably, the transmission rod is fixedly connected to the conical filter plate.

[0014] Compared with the prior art, this utility model provides a sampling device for water conservancy engineering construction, which has the following beneficial effects:

[0015] 1. The filtration mechanism is used to remove large particulate impurities, such as decaying weeds in the water, to provide a cleaner sampling environment for subsequent sampling. Specifically, the sampling motor output drives the first and second turbofans. The second turbofan uses the filtration tube to remove impurities from the water in advance and works with the unblocking mechanism to further remove impurities from the water.

[0016] 2. The unblocking mechanism is used to drive the conical filter plate to shake, preventing impurities from accumulating on the conical filter plate during the sampling process. At the same time, a filter-passing plate is set up to work with the conical filter plate to unblock any impurities that may accumulate on the conical filter plate. After the impurities on the conical filter plate are unblocked, the sampling tube is in a sealed state. After the impurities lose the suction of the first turbine fan, they are removed by the second turbine fan. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Example 1:

[0027] Please see Figure 1-5This utility model provides a technical solution: a sampling device for water conservancy engineering construction, including a sampling box 1, a floating ring 2 fixedly connected to the outside of the sampling box 1, and a sampling tube 3 set on the lower side of the sampling box 1. A filtration mechanism 4 is provided inside the sampling box 1, and a dredging mechanism 5 is provided below the filtration mechanism 4. The filtration mechanism 4 includes a diversion box 401, which is fixedly connected to the inner wall of the sampling tube 3. A sampling motor 402 is fixedly connected inside the diversion box 401. A partition 403 is fixedly connected inside the sampling box 1. 02 The output end is fixedly connected to turbofan 1 404 and turbofan 2 405. A water tank 406 is sleeved on the outside of turbofan 2 405. The water tank 406 is rotatably connected to the outside of the output end of sampling motor 402. A water pipe 407 is connected to the lower surface of the water tank 406. The water pipe 407 is fixedly connected to the water tank 406. An annular pipe 408 is fixedly connected to the lower end of the water pipe 407. An opening 409 is opened on the annular pipe 408. A connecting pipe 410 is connected to the upper end of the water tank 406. The connecting pipe 410 is connected to the space below the partition 403.

[0028] Furthermore, the water tank 406 is connected to the outside of the annular pipe 408 via the water pipe 407, the annular pipe 408, and the opening 409.

[0029] Furthermore, the sampling motor 402 is installed inside the diversion box 401, and the water flows through the outside of the sampling motor 402 into the space above the partition 403 for standby.

[0030] Furthermore, the water pipe 407 is made of rigid material and is used to support the water tank 406. During the output of the sampling motor 402, it drives the first turbo fan 404 and the second turbo fan 405 to rotate. During the rotation of the first turbo fan 404, a suction force is generated inside the sampling tube 3. The sampling liquid enters the sampling box 1 through the sampling tube 3 and the drainage box 401. During this process, the second turbo fan 405 is driven to rotate by the sampling motor 402. The second turbo fan 405 outputs negative pressure in the water tank 406. The annular pipe 408 is set below the conical filter plate 522 and its opening 409 is larger than the opening 409 of the conical filter plate 522. Large particles of impurities will be sucked into the water tank 406 by the negative pressure through the water pipe 407. Subsequently, the impurities enter the space below the partition 403 under the push of the second turbo fan 405, thus initially purifying the sampling environment.

[0031] Example 2:

[0032] Please see Figure 1-5Furthermore, in conjunction with Embodiment 1, it is further obtained that the unblocking mechanism 5 includes an oscillation component 51 and a filter component 52. The oscillation component 51 is disposed on the outside of the filter component 52. The oscillation component 51 includes a waterproof shell 501 and an oscillation motor 503. The waterproof shell 501 is fixedly connected to one side of the sampling box 1. A limit box 502 is fixedly connected to the right side of the waterproof shell 501. The oscillation motor 503 is fixedly connected inside the waterproof box 406. A crank 504 is fixedly connected to the output end of the oscillation motor 503. An annular sleeve 505 is slidably connected inside the limit box 502. The crank 504 is slidably connected to the inner wall of the annular sleeve 505. A transmission rod 506 is fixedly connected to the lower surface of the annular sleeve 505. The transmission rod 506 extends through the limit box 502 to the outside of the limit box 502.

[0033] Furthermore, the filter assembly 52 includes a chute 521, which is formed inside the sampling tube 3. A conical filter plate 522 is slidably connected inside the chute 521. The conical filter plate 522 is disposed on the inner side above the annular pipe 408. A fixing block 523 is fixedly connected to the inner wall of the sampling tube 3. A filter plate 524 is fixedly connected to the inner side of the fixing block 523. A through column 525 is fixedly connected to the lower surface of the filter plate 524.

[0034] Furthermore, the transmission rod 506 is fixedly connected to the conical filter plate 522. The output of the oscillating motor 503 drives the annular sleeve 505 to reciprocate within the limiting box 502. Each rotation of the output end of the oscillating motor 503 causes the annular sleeve 505 to reciprocate once within the limiting box 502. The annular sleeve 505 drives the transmission rod 506 to slide synchronously within the limiting box 502. The transmission rod 506 then drives the conical filter plate 522 to slide synchronously within the sliding groove 521. During the sample extraction process by the turbine fan 404, the suction force generated by the turbine fan 404 may attract impurities from the water onto the conical filter plate 522. These impurities can easily clog the conical filter plate 522, making sampling difficult. During the reciprocating motion of the conical filter plate 522, the surface of the conical filter plate 522... When the surface of the filter plate 522 is in contact with the lower surface of the filter plate 524, the through column 525 on the filter plate 524 clears the impurities accumulated on the conical filter plate 522. At this time, the sampling tube 3 is in a closed state. (A magnetic coupling can be used to connect the turbine fan 404 and the motor output shaft to prevent the pressure imbalance caused by the instantaneous closure of the sampling tube 3. The magnetic coupling can disconnect the turbine fan from the motor output shaft when the rotation pressure increases and reconnect after the pressure is restored.) The lower side of the conical filter plate 522 loses the attraction of the turbine fan 404, while the turbine fan 405 is not affected. Under the attraction of the turbine fan 405, the impurities enter the sampling box 1 through the water pipe 407 and the water tank 406, further eliminating any impurities that may remain on the conical filter plate 522, thus isolating the impurities from the sampling area and ensuring the sampling environment.

[0035] In actual operation, when this device is used, it is placed in water and sampled through sampling tube 3. Under the output of sampling motor 402, turbo fan 404 performs sampling work, turbo fan 405 purifies the environment during the sampling process, and filter plate 524 unclogs and cleans impurities from conical filter plate 522 with the help of oscillating motor 503, so as to ensure that the water quality is not affected by impurities during the sampling process and increase the quality of the sample.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
