Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a deep water quality sampler. Background Art

[0002] Sampling is a critical step in water quality monitoring. Depth is a key factor affecting sampling quality, and different water quality indicators have different depth requirements. For example, suspended solids testing requires capturing the concentration of all suspended solids in the water, while dissolved matter testing requires a shallower depth. For certain high-standard water quality tests, inlet water sampling should generally reach the center of the water body. This is because water quality may vary above and below the center of the water body.

[0003] Existing water quality samplers can seal the sampling tube after taking water to prevent water from other depths from entering the sampling tube. For example, Chinese patent application number CN202320867567.3 discloses a water quality sampler of different depths, including a sampling tube, a counterweight chassis is provided at the bottom of the sampling tube, a sample tube rack is provided at the top of the sampling tube, the sample tube rack is connected to a hand rope, the tube mouth of the sampling tube is equipped with a sample tube plug, and a buoyancy valve that can block the tube mouth is also placed inside the sampling tube.

[0004] The buoyancy valve of this sampler will rise as the water level inside the sampling tube rises until the buoyancy valve blocks the mouth of the sampling tube, thereby achieving a sealing effect. When sampling in rivers and lakes, the sampling tube is easily affected by the water flow under the water surface, causing the sampling tube to tilt. The water inside the sampling tube alone is difficult to effectively support the buoyancy valve, resulting in a change in the position of the buoyancy valve, which in turn allows external water to enter the sampling tube, affecting subsequent detection. Utility Model Content

[0005] Technical problems solved

[0006] In view of the deficiencies in the prior art, the utility model provides a deep water quality sampler, which solves the problem of the sampler being loosely sealed after sampling under the water surface.

[0007] Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a deep water quality sampler, comprising an outer cylinder, the interior of the outer cylinder is slidably connected to a cylinder body, the upper surface of the cylinder body is symmetrically penetrated with an opening, the upper surface of the cylinder body is connected to a rope, the upper surface of the outer cylinder is connected to a sealing tube, the upper end of the rope extends upward and passes through the sealing tube, a limiting ring is connected to the top of the outer cylinder through a connecting rod, a through opening is penetrated on one side of the outer cylinder, a rubber block is fitted inside the through opening, the rubber block is connected to a sealing block away from the rope side, a pull rope is connected to the surface of the sealing block, and the pull rope extends upward and passes through the limiting ring.

[0009] Preferably, a first magnet is connected to the interior of the cylinder, and two second magnets are symmetrically connected to the upper side of the interior of the outer cylinder.

[0010] Preferably, a counterweight is connected to the lower surface of the outer cylinder.

[0011] Preferably, the outer surface of the pull rope is connected to a limiting plate, and the limiting plate is in conflict with the lower surface of the limiting ring.

[0012] Preferably, a gasket is connected to the lower surface of the second magnet.

[0013] Preferably, the surface of the cylinder is covered with rubber.

[0014] Preferably, a fixing frame is connected to the lower surface of the limiting ring, and the fixing frame is located between the rope and the pull rope.

[0015] Beneficial effects

[0016] The utility model provides a deep water quality sampler with the following beneficial effects:

[0017] By setting up the rope, cylinder and other structures, when the outer cylinder reaches the specified depth, the pull rope is pulled to separate the rubber block from the through-hole. At this time, water enters the outer cylinder from the through-hole, and the rope is pulled to raise the height of the cylinder. When the cylinder reaches the height of the through-hole, it will block the through-hole, so that the outer cylinder is in a sealed state and prevent water from continuing to flow into the outer cylinder. Compared with the existing technology, the sealing effect is achieved by pulling the rope to make the cylinder block the through-hole. Continuing to pull the rope can pull the outer cylinder out of the water. Since the cylinder is always subjected to the tension of the rope during the pulling process, even if the outer cylinder is tilted by the impact of the water flow, the cylinder will still remain in the upper position inside the outer cylinder, so that the outer cylinder remains sealed.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-5 The utility model provides a technical solution: a deep water quality sampler, including an outer cylinder 1, which is slidably connected to the cylinder body 2 inside the outer cylinder 1, and an opening is symmetrically penetrated on the upper surface of the cylinder body 2. A rope 3 is connected to the upper surface of the cylinder body 2, and a sealing tube 4 is connected to the upper surface of the outer cylinder 1. The upper end of the rope 3 extends upward and passes through the sealing tube 4. A limiting ring 5 is connected to the upper part of the outer cylinder 1 through a connecting rod. A through opening 6 is penetrated on one side of the outer cylinder 1, and a rubber block 7 is fitted inside the through opening 6. The rubber block 7 is connected to a sealing block 8 on the side away from the rope 3. A pull rope 9 is connected to the surface of the sealing block 8. The pull rope 9 extends upward and passes through the limiting ring 5. The rope 3 and the pull rope 9 are both plastic-coated ropes, and their performance is coated with PVC, which is the existing technology and will not be repeated here. The outer surface of the rope 3 is in contact with the inner wall of the sealing tube 4. The sealing tube 4 is made of silicone, and the sealing block 8 is in contact with the surface of the outer cylinder 1.

[0026] During operation, hold the upper end of the pull rope 9 and put the outer cylinder 1 into the water. After the outer cylinder 1 is placed in the specified depth, pull the pull rope 9 upward to pull up the sealing block 8, and the sealing block 8 drives the rubber block 7 to disengage from the through-port 6. At this time, water flows into the outer cylinder 1 from the through-port 6. After there is enough sample in the outer cylinder 1, pull the rope 3 upward to move the cylinder body 2 upward and reach the same height as the through-port 6. At this time, the upper surface of the cylinder body 2 fits with the inner wall of the outer cylinder 1, and the cylinder body 2 will block the through-port 6, so that the outer cylinder 1 is in a sealed state to prevent external water from continuing to enter the interior of the outer cylinder 1. Continue to pull the rope 3 until the outer cylinder 1 is pulled out of the water to complete the sampling.

[0027] See also Figures 1-5 The utility model provides a technical solution: a first magnet 10 is connected to the inside of the cylinder 2, and two second magnets 11 are symmetrically connected to the upper side of the inner part of the outer cylinder 1. The two second magnets 11 correspond to the two opening positions on the upper surface of the cylinder 2.

[0028] During operation, when the upper surface of the cylinder 2 fits against the inner wall of the outer cylinder 1, the first magnet 10 and the second magnet 11 will also fit together, and the first magnet 10 and the second magnet 11 will produce a magnetic attraction effect, which can improve the stability of the cylinder 2 in the current position.

[0029] See also Figures 1-5 The utility model provides a technical solution: a counterweight block 12 is connected to the lower surface of the outer cylinder 1.

[0030] During operation, the counterweight 12 can be arranged to move the entire center of the sampler downward, thereby improving the stability of the outer cylinder 1 during use.

[0031] See also Figures 1-5 The utility model provides a technical solution: the outer surface of the pull rope 9 is connected to a limiting piece 13, the limiting piece 13 conflicts with the lower surface of the limiting ring 5, and the limiting piece 13 is made of rubber.

[0032] During operation, the setting of the limiting piece 13 can increase the friction between the pull rope 9 and the limiting ring 5, thereby improving the stability of the outer tube 1 when it is lowered into the water.

[0033] See also Figures 1-5 The utility model provides a technical solution: a gasket 14 is connected to the lower surface of the second magnet 11, and the gasket 14 is made of rubber.

[0034] During operation, the spacer 14 can play a buffering role between the first magnet 10 and the second magnet 11 to prevent the first magnet 10 and the second magnet 11 from contacting too quickly and causing debris.

[0035] See also Figures 1-5 The utility model provides a technical solution: the surface of the cylinder 2 is covered with rubber.

[0036] During operation, by coating the surface of the cylinder 2 with rubber, the sealing performance between the cylinder 2 and the through port 6 can be improved.

[0037] See also Figures 1-5 The utility model provides a technical solution: the lower surface of the limiting ring 5 is connected to a fixing frame 15, and the fixing frame 15 is located between the rope 3 and the pull rope 9.

[0038] During operation, when the sealing block 8 is pulled up, it will be stuck between the limiting ring 5 and the fixing frame 15. The setting of the fixing frame 15 can prevent the sealing block 8 from being released from the rope 3, which is beneficial to the subsequent normal use of the rope 3.

[0039] In summary, hold the upper end of the pull rope 9 and put the outer cylinder 1 into the water. After the outer cylinder 1 is placed in the specified depth, pull the pull rope 9 upward to pull up the sealing block 8, and the sealing block 8 drives the rubber block 7 to disengage from the through-port 6. At this time, the water flows into the outer cylinder 1 from the through-port 6. After there is enough sample in the outer cylinder 1, pull the rope 3 upward to move the cylinder 2 upward and reach the same height as the through-port 6. At this time, the upper surface of the cylinder 2 fits with the inner wall of the outer cylinder 1, and the cylinder 2 will block the through-port 6, so that the outer cylinder 1 is in a sealed state, preventing the external water flow from continuing to enter the interior of the outer cylinder 1. At the same time, the first magnet 10 and the second magnet 11 will fit together, and the magnetic attraction effect generated by the first magnet 10 and the second magnet 11 can improve the stability of the cylinder 2 in the current position. Continue to pull the rope 3 until the outer cylinder 1 is pulled out of the water to complete the sampling.
