Description

Technical Field

[0001] This utility model relates to the technical field of oil sampling equipment, and in particular to a portable manual oil sampler. Background Technology

[0002] In many fields such as environmental monitoring, petrochemicals, food processing, and water conservancy projects, the detection and analysis of oily substances is a key link in assessing the degree of water pollution, ensuring product quality, and ensuring project safety. The accurate collection of oily samples is the basic prerequisite for all subsequent testing work, and the quality of the sampling directly determines the accuracy and reliability of the test results.

[0003] In real-world sampling scenarios, different monitoring tasks have varying requirements for sampling depth. Some scenarios require collecting oil samples from shallow water (depth less than the sampler's own height), while others require collecting samples from deep water (depth greater than the sampler's own height). However, some traditional samplers use simple sampling bottles, which are only suitable for sampling in shallow water and cannot meet the diverse depth sampling needs.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a portable manual oil sampler to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a portable manual oil sampler, which aims to solve the following problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable manual oil sampler includes a sampling cylinder with a bottom cover fixedly connected to its bottom end. The bottom cover has multiple evenly distributed feed holes. A top cover is fixedly connected to the top end of the sampling cylinder, and the top cover has an air outlet. A support cylinder is also fixedly connected to the top cover. A handle is fixedly connected to the upper end of the support cylinder. A sliding rod is slidably connected inside the top cover. A lifting assembly is fitted between the handle and the sliding rod. A sealing plate is fixedly connected to the lower end of the sliding rod through the bottom cover. Multiple evenly distributed sealing plugs are fixedly connected to the sealing plate, and each sealing plug corresponds to one of the feed holes. A symmetrically distributed second limiting groove is formed on the inner wall of the support cylinder. A symmetrically distributed second limiting block is fixedly connected to the outer wall of the sliding rod, and each second limiting block corresponds to one of the second limiting grooves. The second limiting block is slidably connected to the inner wall of the corresponding second limiting groove. A spring is provided between the second limiting block and the top cover, and the spring is sleeved on the outer wall of the sliding rod.

[0008] In a further technical solution, both the feed hole and the sealing plug are in the shape of a frustum.

[0009] In a further technical solution, a flexible hose is fixedly connected to the air outlet.

[0010] In a further technical solution, the outer wall of the support cylinder is provided with a first scale line, and the outer wall of the sampling cylinder is provided with a second scale line.

[0011] A further technical solution includes a sliding groove, a first limiting groove, a first limiting block, a sliding plate, a rotating plate, and an opening groove; the side wall of the support cylinder has an opening groove, and the handle has a sliding groove. The inner walls of the sliding grooves are provided with first limiting grooves on both sides. The inner walls of the sliding grooves are slidably connected to the sliding plate, and the two sides of the sliding plate are fixedly connected to the first limiting blocks. The first limiting blocks correspond one-to-one with the first limiting grooves. The first limiting blocks are slidably connected to the inner walls of the corresponding first limiting grooves. The lower end of the sliding plate is rotatably connected to the sliding rod, and the rotating plate abuts against the inner wall of the opening groove.

[0012] In a further technical solution, the upper end of the skateboard is higher than the upper surface of the handle.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. The lifting assembly drives the slide bar to descend, which in turn drives the sealing plate to descend. The sealing plate then drives the sealing plug to disengage from the feed hole, thereby opening the feed hole. The sample enters the sampling cylinder through the feed hole, and the air in the sampling cylinder is discharged through the air outlet. After sampling is completed, the sliding plate is released, and the spring pushes the second limit block to slide upward along the inner wall of the second limit groove. Then, the second limit block drives the slide bar to move upward, and the slide bar drives the sealing plate to move upward until the sealing plate drives the sealing plug to block the feed hole. When the sampling depth is lower than the height of the sampling cylinder, it can be directly observed and sampled through the second scale line. When the sampling depth is higher than the height of the sampling cylinder, the sampling depth is observed through the first scale line. By connecting a hose to the air outlet, the air in the sampling cylinder is discharged through the hose, thereby achieving deep sampling and adapting to sampling needs at different depths.

[0015] 2. The spring pushes the second limiting block to slide upward along the inner wall of the second limiting groove. Then the second limiting block drives the slide rod to move upward, and the slide rod drives the sealing plate to move upward until the sealing plate drives the sealing plug to block the feed hole, thereby effectively preventing the operator from pushing the slide plate to reset and reducing labor intensity.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1-3 As shown, this utility model embodiment provides a portable manual oil sampler, including a sampling cylinder 1. A bottom cover 2 is fixedly connected to the bottom end of the sampling cylinder 1. The bottom cover 2 has multiple evenly distributed feed holes 3. A top cover 7 is fixedly connected to the upper end of the sampling cylinder 1. An air outlet 8 is provided on the top cover 7. A support cylinder 9 is also fixedly connected to the top cover 7. A handle 10 is fixedly connected to the upper end of the support cylinder 9. A sliding rod 6 is slidably connected inside the top cover 7. A lifting assembly 11 is provided between the handle 10 and the sliding rod 6. The lower end of the sliding rod 6 passes through the bottom cover. A sealing plate 4 is fixedly connected to the 2, and a plurality of evenly distributed sealing plugs 5 are fixedly connected to the sealing plate 4. The sealing plugs 5 correspond one-to-one with the feed holes 3. The inner wall of the support cylinder 9 is provided with symmetrically distributed second limiting grooves 12. The outer wall of the slide rod 6 is fixedly connected with symmetrically distributed second limiting blocks 13. The second limiting blocks 13 correspond one-to-one with the second limiting grooves 12. The second limiting blocks 13 are slidably connected to the inner wall of the corresponding second limiting grooves 12. A spring 14 is provided between the second limiting blocks 13 and the top cover 7. The spring 14 is sleeved on the outer wall of the slide rod 6.

[0024] Furthermore, all three sealing plugs 5 of the feed hole are frustum-shaped.

[0025] Furthermore, the hole in which the top cover 7 and the slide rod 6 slide together is tightly fitted with an elastic sealing element (such as a sealing ring) to seal the gap.

[0026] Furthermore, a flexible hose is fixedly connected to the air outlet 8, so that when the sampling cylinder 1 is submerged, the gas inside the sampling cylinder 1 can be discharged through the flexible hose, thereby allowing the sample to enter the sampling cylinder 1 through the feed hole 3.

[0027] Furthermore, the outer wall of the support cylinder 9 is provided with a first scale line 15, and the outer wall of the sampling cylinder 1 is provided with a second scale line (not shown in the figure). The sampling depth is observed through the first scale line 15 and the second scale line.

[0028] like Figure 1 and Figure 2 As shown, the lifting assembly 11 includes a slide groove 111, a first limiting groove 112, a first limiting block 113, a slide plate 114, a rotating plate 115, and an opening groove 116. The side wall of the support cylinder 9 has an opening groove 116, and the handle 10 has a slide groove 111. The inner walls of the slide groove 111 are provided with first limiting grooves 112 on both sides. The inner wall of the slide groove 111 is slidably connected to the slide plate 114. The two sides of the slide plate 114 are fixedly connected with first limiting blocks 113. The first limiting blocks 113 correspond one-to-one with the first limiting grooves 112. The first limiting blocks 113 are slidably connected to the inner walls of the corresponding first limiting grooves 112. The lower end of the slide plate 114 is rotatably connected to the slide rod 6, and the rotating plate 115 abuts against the inner wall of the opening groove 116.

[0029] Furthermore, the upper end of the skateboard 114 is higher than the upper surface of the handle 10, which facilitates the movement of the skateboard 114.

[0030] In practical application, the slide plate 114 is pushed to slide along the inner wall of the slide groove 111 towards the support cylinder 9. Then the slide plate 114 drives the rotating plate 115 to move. The rotating plate 115 drives the slide rod 6 to descend. The slide rod 6 drives the sealing plate 4 to descend. Then the sealing plate 4 drives the sealing plug 5 to disengage from the feed hole 3, thereby opening the feed hole 3.

[0031] In this embodiment of the invention, the lifting assembly 11 drives the sliding rod 6 to descend, which in turn drives the sealing plate 4 to descend. The sealing plate 4 then drives the sealing plug 5 to disengage from the feed hole 3, thereby opening the feed hole 3. The sample enters the sampling cylinder 1 through the feed hole 3, and air inside the sampling cylinder 1 is discharged through the air outlet 8. After sampling is completed, the sliding plate 114 is released, and the spring 14 pushes the second limiting block 13 to slide upward along the inner wall of the second limiting groove 12. Then, the second limiting block 13 drives the sliding rod 6 to move upward, which in turn drives the sealing plate 4 to move upward until the sealing plate 4 drives the sealing plug 5 to seal the feed hole 3. When the sampling depth is lower than the height of the sampling cylinder 1... Sampling can be directly observed and taken through the second scale line. When the sampling depth is higher than the sampling cylinder height 1, the sampling depth can be observed through the first scale line 15. By connecting the air outlet 8 to the hose, the air in the sampling cylinder 1 can be discharged through the hose, thereby achieving deep sampling and adapting to sampling needs of different depths. The spring 14 pushes the second limit block 13 to slide upward along the inner wall of the second limit groove 12. Then the second limit block 13 drives the slide rod 6 to move upward, and the slide rod 6 drives the sealing plate 4 to move upward until the sealing plate 4 drives the sealing plug 5 to block the feed hole 3, thereby effectively preventing the operator from pushing the slide plate 114 to reset and reducing labor intensity.

[0032] The working principle of this utility model is as follows: When the sampling depth is lower than the height of the sampling cylinder 1, the sampler is placed in the surface water. Then, the depth reached by the bottom end of the bottom cover 2 is observed through the second scale line. After reaching the target depth, the sliding plate 114 is pushed to slide along the inner wall of the sliding groove 111 towards the support cylinder 9. Then, the sliding plate 114 drives the rotating plate 115 to move, the rotating plate 115 drives the sliding rod 6 to descend, the sliding rod 6 drives the sealing plate 4 to descend, and then the sealing plate 4 drives the sealing plug 5 to disengage from the feed hole 3, thereby opening the feed hole 3. The sample enters the sampling cylinder 1 from the feed hole 3, and the air in the sampling cylinder 1 is discharged through the air outlet 8. After sampling is completed, the sliding plate 114 is released, the spring 14 pushes the second limiting block 13 to slide upward along the inner wall of the second limiting groove 12, and then the second limiting block 13 drives the sliding rod 6 to move upward, the sliding rod 6 drives the sealing plate 4 to move upward, until the sealing plate 4 drives the sealing plug 5 to seal the feed hole 3; when the sampling depth is higher than the target depth, the sampler is placed in the surface water. The ... When the sampling cylinder 1 is at its height, the flexible tube is attached to the air outlet 8, and the sampler is placed in the surface water. Then, the depth reached by the bottom of the bottom cover 2 is observed through the first scale line 15. After reaching the target depth, the sliding plate 114 is pushed to slide along the inner wall of the slide groove 111 towards the support cylinder 9. Then, the sliding plate 114 drives the rotating plate 115 to move, the rotating plate 115 drives the sliding rod 6 to descend, the sliding rod 6 drives the sealing plate 4 to descend, and then the sealing plate 4 drives the sealing plug 5 to disengage from the feed hole 3, thereby opening the feed hole 3. The sample enters the sampling cylinder 1 from the feed hole 3. The air in the sampling cylinder 1 enters the flexible tube through the air outlet 8 and is then discharged through the flexible tube. After sampling is completed, the sliding plate 114 is released, and the spring 14 pushes the second limiting block 13 to slide upward along the inner wall of the second limiting groove 12. Then, the second limiting block 13 drives the sliding rod 6 to move upward, the sliding rod 6 drives the sealing plate 4 to move upward, until the sealing plate 4 drives the sealing plug 5 to block the feed hole 3.
