Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a sampling device for water conservancy engineering testing. Background Technology
[0002] During the construction and operation of water conservancy projects, it is necessary to regularly sample the water environment. Only by taking samples can various subsequent performance tests be conducted to assess information on water pollution, ecological health, and water resource management, ensuring the safety of project operation and confirming that water conservancy operations will not have a negative impact on the water environment.
[0003] Existing technologies, such as patent number CN220568485U, can sample water sources at different depths in a single descent and prevent water from other depths from mixing into the already sampled sampling chamber, ensuring the integrity of samples from each water source depth. However, the more sampling chambers there are, the more electric telescopic rods are required, which increases costs. Therefore, this application provides a sampling device for water conservancy engineering testing to meet the requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a sampling device for water conservancy engineering testing, so as to solve the problem that the more sampling chambers there are, the more electric telescopic rods are required, which leads to increased costs.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A sampling device for water conservancy engineering testing includes an outer shell. A top cover is mounted on the top of the outer shell via two locking mechanisms. A water storage cylinder is disposed inside the outer shell, penetrating the bottom of the outer shell and fixedly connected thereto. Multiple equally spaced partitions are fixedly connected from bottom to top inside the water storage cylinder. An inner inlet and an inner outlet are provided vertically on one side of the inner wall of the water storage cylinder between the partitions and between the partitions and the top of the water storage cylinder. A sampling mechanism is mounted on the outer surface of the water storage cylinder. The sampling mechanism includes multiple sealing blocks sleeved on the water storage cylinder and blocking the inner inlets and outlets. A passage is provided on the side of each sealing block. The first opening is at the same height as the inner water inlet. On the opposite side of the first opening, a second opening is also provided on the sealing block. The second opening is at the same height as the inner water outlet. The sealing blocks are fixedly connected together by two connecting rods. The top end of each connecting rod is fixedly connected to the same turntable. The bottom of the turntable can abut against the top of the water storage cylinder. An eccentrically set limiting rod is fixedly connected to the top of the turntable. A fixing plate is fixedly connected to the inner wall of the top cover. An electric telescopic rod is installed on the top of the fixing plate. One end of the electric telescopic rod is fixedly connected to a limiting strip sleeved on the limiting rod. The limiting rod can slide inside the limiting strip.
[0007] Preferably, the outer surface of the outer casing has a plurality of external water inlets and external water outlets arranged vertically, and the number and position of the external water inlets and external water outlets correspond to the number and position of the internal water inlets and internal water outlets.
[0008] Preferably, the bottom inner wall of the outer casing abuts against the bottom of the sealing block at the lowest point on the water storage cylinder.
[0009] Preferably, the outer wall of the outer shell has two opposing grooves, the outer wall of the top cover has two opposing limiting grooves, the locking mechanism includes a "C"-shaped limiting frame, one end of the limiting frame is slidably connected to the groove, the other end of the limiting frame away from the groove is fixedly connected to a limiting block, the limiting block slides inside the limiting groove, and a spring is provided between the limiting block and one inner wall of the limiting groove.
[0010] Preferably, a rubber ring is fixedly connected to the bottom of the top cover to prevent water from entering the interior of the top cover and the outer casing.
[0011] Preferably, a counterweight is provided on the bottom inner wall of the water storage cylinder, and the top of the counterweight abuts against the partition plate.
[0012] Compared with the prior art, this utility model has at least the following beneficial effects:
[0013] In the above scheme, by setting up a sampling mechanism, when sampling is needed, a rope is connected to the top of the outer shell, and the electric telescopic rod is activated, extending a small portion of the rod. This causes the limiting strip to rotate the turntable via the limiting rod. The rotation of the turntable rotates the connecting rod, which in turn rotates the sealing block, blocking both openings one and two on the sealing block against the inner wall of the outer shell. The outer shell is then placed into the water area to be sampled. The electric telescopic rod is then activated again, retracting to rotate the turntable. This, via the connecting rod, rotates the sealing block, connecting one side of opening one to the inner inlet and the other side to the outer inlet. Water then flows from the outside through the outer inlet, opening one, and the inner inlet into the water storage tank, ensuring water is stored between the partitions and between the partitions and the top of the water storage tank. After water sampling is completed, the sample is then... The electric telescopic rod is activated, causing the turntable to rotate and the sealing block to be blocked again by the inner wall of the outer casing, stopping the water intake. The outer casing can then be removed from the water area to be sampled using a rope. When the water sample inside the storage tank needs to be removed, the electric telescopic rod is activated to extend to the top, causing the turntable to rotate the sealing block via the connecting rod. When the electric telescopic rod extends to the top, one side of the second opening will connect to the inner outlet, and the other side will connect to the outer outlet. Water will flow out from inside the storage tank through the inner outlet, the second opening, and the outer outlet. The advantage of this method is that it ensures that water sources at different depths can be sampled, ensuring the integrity of the water source depth samples, while also saving on the use of too many electric telescopic rods. Only one electric telescopic rod is needed to complete the sampling and collection of water sources at different depths, saving on usage costs.
[0014] By setting up a locking mechanism, when a problem occurs inside the outer casing and requires repair, simply pull the limiting brackets on both sides of the outer casing outwards. This allows the limiting block at one end of the limiting bracket to slide inside the limiting groove, stretching the spring. The other end of the limiting bracket will then slide out of the groove. At this point, lifting the top cover upwards will separate the top cover from the outer casing, allowing operation to be performed inside the outer casing or the top cover. This prevents the difficulty of disassembly when a problem occurs inside the outer casing and requires repair. After the repair is completed, pull the limiting bracket again, aligning one end of the limiting bracket with the inside of the groove. Releasing the limiting bracket will cause the reset spring to reinstall one end of the limiting bracket into the groove, completing the installation. Attached Figure Description

Detailed Implementation
[0024] The sampling device for water conservancy engineering testing provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should also be noted that, in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can also use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.
[0025] like Figures 1-5As shown, an embodiment of this utility model provides a sampling device for water conservancy engineering testing, including an outer shell 1. A top cover 2 is installed on the top of the outer shell 1 through two locking mechanisms 5. A water storage cylinder 6 is arranged inside the outer shell 1, penetrating the bottom of the outer shell 1 and fixedly connected to it. Multiple equally spaced partitions 8 are fixedly connected from bottom to top inside the water storage cylinder 6. The partitions 8 and the partitions 8 are located on one side of the inner wall of the water storage cylinder 6. The water storage cylinder 6 has an inner inlet 9 and an inner outlet 10 arranged vertically. A sampling mechanism 7 is installed on the outer surface of the water storage cylinder 6. The sampling mechanism 7 includes multiple sealing blocks 71 that are sleeved on the water storage cylinder 6 and block the inner inlet 9 and the inner outlet 10. A first opening 73 is opened on the side of the sealing block 71. The first opening 73 is at the same height as the inner inlet 9. On the opposite side of the first opening 73, a second opening 74 is also opened on the sealing block 71. The second opening 74 is at the same height as the inner outlet 10. Similarly, the sealing blocks 71 are fixedly connected together by two connecting rods 72. The top end of each connecting rod 72 is fixedly connected to the same turntable 75. The bottom of the turntable 75 can abut against the top of the water storage cylinder 6. An eccentrically positioned limiting rod 76 is fixedly connected to the top of the turntable 75. A fixing plate 14 is fixedly connected to the inner wall of the top cover 2. An electric telescopic rod 78 is installed on the top of the fixing plate 14. One end of the electric telescopic rod 78 is fixedly connected to a limiting rod sleeved on the limiting rod 76. The limiting strip 77 and the limiting rod 76 can slide inside the limiting strip 77. The outer surface of the outer shell 1 is provided with multiple external water inlets 3 and external water outlets 4 arranged vertically. The number and position of the external water inlets 3 and external water outlets 4 correspond to the number and position of the internal water inlets 9 and internal water outlets 10. The bottom inner wall of the outer shell 1 abuts against the bottom of the sealing block 71 at the lowest point on the water storage cylinder 6. The bottom inner wall of the water storage cylinder 6 is provided with a counterweight 11, and the top of the counterweight 11 abuts against the partition plate 8.
[0026] By setting up the sampling mechanism 7, when sampling is needed, a rope is connected to the top of the outer shell 1, and the electric telescopic rod 78 is activated, extending a small portion of the electric telescopic rod 78. This causes the limiting strip 77 to rotate the turntable 75 via the limiting rod 76. The rotation of the turntable 75 drives the connecting rod 72, which in turn drives the sealing block 71 to rotate. This causes both the first opening 73 and the second opening 74 on the sealing block 71 to be blocked by the inner wall of the outer shell 1. At this point, the outer shell 1 is placed into the water area to be sampled. The electric telescopic rod 78 is then activated again, causing it to retract and rotate the turntable 75. This, via the connecting rod 72, causes the sealing block 71 to rotate, connecting one side of the first opening 73 to the inner inlet 9 and the other side to the outer inlet 3. Water then enters the water storage tank 6 from the outside through the outer inlet 3, the first opening 73, and the inner inlet 9, storing water between the partitions 8 and between the partitions 8 and the top of the water storage tank 6. After the water sample is collected, Activating the electric telescopic rod 78 again drives the turntable 75 to rotate the sealing block 71, causing the openings 73 and 74 on the sealing block 71 to be blocked again by the inner wall of the outer casing 1, stopping water intake. The outer casing 1 can then be removed from the water area to be sampled using a rope. When it is time to remove the water sample from inside the water storage tank 6, the electric telescopic rod 78 is activated to extend to the top, causing the turntable 75 to rotate the sealing block 71 via the connecting rod 72. When the electric telescopic rod 78 extends to the top, one side of the opening 74 will connect to the inner outlet 10, and the other side will connect to the outer outlet 4. Water will flow out from inside the water storage tank 6 through the inner outlet 10, the opening 74, and the outer outlet 4. The advantage of this is that it ensures that water sources at different depths can be sampled, ensuring the integrity of the water source depth samples, while also saving on the use of too many electric telescopic rods 78. Only one electric telescopic rod 78 is needed to complete the sampling and collection of water sources at different depths, saving on usage costs.
[0027] like Figure 1 , Figure 2 and Figure 5 As shown, two opposing grooves 12 are provided on the outer wall of the outer shell 1, and two opposing limiting grooves 13 are provided on the outer wall of the top cover 2. The locking mechanism 5 includes a limiting frame 51 in the shape of a "C". One end of the limiting frame 51 is slidably connected to the groove 12, and the other end of the limiting frame 51 away from the groove 12 is fixedly connected to a limiting block 52. The limiting block 52 slides inside the limiting groove 13. A spring 53 is provided between the limiting block 52 and one side inner wall of the limiting groove 13. A rubber ring 15 is fixedly connected to the bottom of the top cover 2 to prevent water from entering the interior of the top cover 2 and the outer shell 1.
[0028] By setting the locking mechanism 5, when there is a problem inside the outer shell 1 that needs to be repaired, simply pull the limiting brackets 51 on both sides of the outer shell 1 outward, so that the limiting block 52 at one end of the limiting bracket 51 slides inside the limiting groove 13, stretching the spring 53, and the other end of the limiting bracket 51 will slide out of the groove 12. At this time, lifting the top cover 2 upward will separate the top cover 2 from the outer shell 1, allowing operation inside the outer shell 1 or inside the top cover 2. The advantage of this is that it prevents the problem of difficult disassembly when there is a problem inside the outer shell 1 that needs to be repaired. After the repair is completed, pull the limiting bracket 51 again, so that one end of the limiting bracket 51 is aligned with the inside of the groove 12. After releasing the limiting bracket 51, the reset spring 53 will allow one end of the limiting bracket 51 to be reinstalled into the groove 12, completing the installation.
[0029] The technical solution provided by this utility model involves setting up a sampling mechanism 7. When sampling is required, a rope is connected to the top of the outer shell 1, and the electric telescopic rod 78 is activated, extending a small portion. This causes the limiting strip 77 to rotate the turntable 75 via the limiting rod 76. The rotation of the turntable 75 drives the connecting rod 72, which in turn drives the sealing block 71 to rotate. This causes both the first opening 73 and the second opening 74 on the sealing block 71 to be blocked by the inner wall of the outer shell 1. At this point, the... The outer casing 1 is placed in the water area to be sampled, and then the electric telescopic rod 78 is activated to retract, causing the turntable 75 to rotate. This, via the connecting rod 72, drives the sealing block 71 to rotate, connecting one side of the inlet 73 to the inner inlet 9 and the other side to the outer inlet 3. Water then flows from the outside through the outer inlet 3, the inlet 73, and the inner inlet 9 into the water storage tank 6, ensuring water is stored between the partitions 8 and between the partitions 8 and the top of the water storage tank 6. When the sample is collected... After the water sample is collected, the electric telescopic rod 78 is activated again, driving the turntable 75 to rotate the sealing block 71. This causes the openings 73 and 74 on the sealing block 71 to be blocked again by the inner wall of the outer shell 1, stopping the water intake. The outer shell 1 can then be removed from the water area to be sampled using a rope. When it is time to remove the water sample from inside the water storage cylinder 6, the electric telescopic rod 78 is activated to extend to the top, allowing the turntable 75 to rotate the sealing block 71 via the connecting rod 72. When the electric telescopic rod 78 extends to the top, one side of the opening 74 will connect to the inner outlet 10, and the other side will connect to the outer outlet 4. Water will flow out from inside the water storage cylinder 6 through the inner outlet 10, the opening 74, and the outer outlet 4. The advantage of this method is that it ensures that water sources at different depths can be sampled, ensuring the integrity of the water source depth samples, while also saving on the use of too many electric telescopic rods 78. Only one electric telescopic rod 78 is needed to complete the sampling and collection of water sources at different depths, saving on usage costs.
[0030] By setting the locking mechanism 5, when there is a problem inside the outer shell 1 that needs to be repaired, simply pull the limiting brackets 51 on both sides of the outer shell 1 outward, so that the limiting block 52 at one end of the limiting bracket 51 slides inside the limiting groove 13, stretching the spring 53, and the other end of the limiting bracket 51 will slide out of the groove 12. At this time, lifting the top cover 2 upward will separate the top cover 2 from the outer shell 1, allowing operation inside the outer shell 1 or inside the top cover 2. The advantage of this is that it prevents the problem of difficult disassembly when there is a problem inside the outer shell 1 that needs to be repaired. After the repair is completed, pull the limiting bracket 51 again, so that one end of the limiting bracket 51 is aligned with the inside of the groove 12. After releasing the limiting bracket 51, the reset spring 53 will allow one end of the limiting bracket 51 to be reinstalled into the groove 12, completing the installation.
