Description

Technical Field

[0001] The invention relates to the technical field of water resource sampling equipment, and in particular to a sampling device for hydrological and water resource ecological detection. Background Art

[0002] Hydrology refers to various phenomena such as the changes and movements of water in nature. Water resources refer to water sources that can be used or have the potential to be used. This water source should have sufficient quantity and appropriate quality and meet the specific utilization needs of a certain place within a period of time. Water resources refer to water on the earth with a certain quantity and available quality that can be supplemented and used from nature. Due to the increasingly rapid development of industry, the environment is becoming more and more polluted. Water, as an important resource, must be managed more strictly. It is necessary to understand the water quality of each water source for targeted management. Therefore, it is necessary to collect and sample water from the water source.

[0003] In the prior art, when opening the lid of a horizontal sampling bin, the user first presses the limit switch to place the limit switch in a specified position, and then pulls up the lower end of the connecting frame on the bin cover so that the upper end of the connecting frame on the bin cover rests under the limit switch. When multiple sampling samples are needed, the lids of multiple horizontal sampling bins need to be opened manually, which is not only time-consuming and laborious, but also difficult to quickly collect samples from multiple sampling bins and quickly perform the next sampling when multiple sampling of the water area is required, resulting in low sampling efficiency.

[0004] Therefore, the present application provides a sampling device for hydrological and water resource ecological detection to meet the needs. Summary of the invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, the connecting block is pushed to move downward inside the main body by pressing the control pressure rod, and the two opening and closing connecting strips are rotatably connected to each other through the connection block, so that the two opening and closing connecting strips are relatively rotated on the connection block, so that the opening and closing angles of the two opening and closing connecting strips are gradually reduced, so that when the control pressure rod is pressed down, the two connecting frames can be pulled by the two opening and closing connecting strips to rotate around the rotating connection frame as the axis to open the sealing cover, and then the two sealing covers can be opened at one time by pressing, which saves time and effort, and when performing multi-bin sampling, after multiple sampling devices are installed on the multi-bin sampling mechanism, multiple sampling devices can be opened at one time by pressing the multi-bin connection frame downward. The sealing cover on the horizontal sampling chamber of the device is opened, which improves the convenience of the sampling device during use, and in this way, after the sample collection is completed, the collecting vessel can be placed under each horizontal sampling chamber, and the sealing covers on multiple horizontal sampling chambers can be opened at one time to allow the sample to flow into the vessel containing the sample, so that the samples inside the multiple horizontal sampling chambers can be quickly collected, and the next sampling can be carried out immediately after the samples are collected, which greatly improves the efficiency of the sampling work, and after the sealing covers of the multiple sampling devices are opened, the top of the support sheet will be against the bottom of the multi-chamber connecting frame, thereby improving the stability of the overall support of the multi-chamber sampling mechanism and the multiple sampling devices.

[0017] By controlling the pressure rod to descend and drive the connecting frame and the sealing cover to open the opening of the horizontal sampling chamber, the blocking connecting frame is simultaneously pushed down, so that the opening and closing angle between the two double-headed connecting strips gradually increases, and the two interlocking sealing plates inside the horizontal sampling chamber can be pushed to move outward at both ends of the horizontal sampling chamber. Therefore, when there are many debris in the water area to be sampled, the device can prevent larger debris inside the water area from entering the entrance of the horizontal sampling chamber through the anti-stuck frame after entering the water, thereby avoiding that when the sealing cover is reset to close the entrance of the horizontal sampling chamber, large debris is stuck at the entrance of the horizontal sampling chamber, affecting the sealing of the sealing cover on the horizontal sampling chamber, thereby avoiding the outflow of samples taken from the horizontal sampling chamber when the sampling device is taken out of the water.

[0018] When water flows through the anti-stuck frame and enters the interior of the horizontal sampling bin, an interlocking closing plate is provided on the side of the two anti-stuck frames away from each other. When water flows through the anti-stuck frame and enters the interior of the horizontal sampling bin, it will not enter the anti-stuck frame and the horizontal sampling bin from the position of the interlocking closing plate, thereby preventing water from actively flowing to the end face of the interlocking closing plate with debris when entering the interior of the horizontal sampling bin, reducing the probability of debris being sandwiched between the interlocking closing plate and the sealing cover during the sealing process of the horizontal sampling bin by the sealing cover, thereby reducing the impact of debris on the sealing process of the horizontal sampling bin by the sealing cover during sampling.

The closing mechanism 2 is used to block the entrance and exit of the horizontal sampling chamber 101. The closing mechanism 2 includes two connecting frames 201, and the two connecting frames 201 are rotatably connected to the inside of two rotating connecting frames 102 respectively, and the two connecting frames 201 are symmetrically arranged with the horizontal sampling chamber 101 as the center. The two connecting frames 201 are fixedly connected with sealing covers 202 on one side close to each other, and two tensioning springs 203 are fixedly connected between the two sealing covers 202. The two sealing covers 202 are respectively arranged corresponding to the two entrances and exits of the horizontal sampling chamber 101, and the two connecting frames 201 are rotatably connected on one side close to each other. The two opening and closing connecting strips 204 are connected, and the connecting block 205 is rotatably connected between the two opening and closing connecting strips 204. The pressing control lever 301 is pushed to push the connecting block 205 to move downward inside the main body 1, and the two opening and closing connecting strips 204 are rotatably connected to the connecting block 205, so that the two opening and closing connecting strips 204 are relatively rotated on the connecting block 205, so that the opening and closing angles of the two opening and closing connecting strips 204 are gradually reduced, so that the two connecting frames 201 can be pulled by the two opening and closing connecting strips 204 to rotate around the rotating connecting frame 102 as the axis while the pressing control lever 301 is lowered, so that the sealing cover 202 can be opened, and then the two sealing covers 202 can be opened at the same time by pressing; like Figure 2 , Figure 3 , Figures 5 to 7 and Fig.10As shown, it includes a pressing mechanism 3, which is arranged inside the main body 1. The pressing mechanism 3 includes a control pressing rod 301, which is slidably connected inside the main body 1. The pressing mechanism 3 is used to control the closing mechanism 2 to open and close the entrance and exit of the horizontal sampling chamber 101. The pressing mechanism 3 also includes an extended connecting plate 302, which is fixedly connected to the outer wall of the control pressing rod 301 at one end close to the top outer wall of the main body 1. The connecting block 205 is fixedly connected to the outer wall of the control pressing rod 301.

Two bayonet holes 306 are provided at the bottom of the limit block 305. The position of the stopper 305 near the bayonet 306 corresponds to the inclined surface of the right-angled triangle block 106 for use in conjunction with the inner movable box 105, and the right-angled triangle block 106 is slidably connected to the inner movable box 105, and the right-angled triangle block 106 is slidably connected to the inner movable box 105. In the process of pressing the control lever 301, the stopper 305 is simultaneously driven to slide downward inside the inner movable box 105. In this process, the position of the bottom of the stopper 305 near the bayonet 306 will abut against the inclined surface of the right-angled triangle block 106, and through the inclined surface of the right-angled triangle block 106, the stopper 305 is in contact with the inner movable box 105. When the opening 306 continues to move downward, it will push the right-angled triangle block 106 to slide through the side wall of the inner movable box 105 and stretch the reset spring 108. When the right-angled triangle block 106 completely enters the inside of the bayonet 306, the horizontal sampling chamber 101 is in an open state, and the elasticity of the reset spring 108 will push the right-angled triangle block 106 to reset, so that the bottom of the right-angled triangle block 106 is against the inner wall of the bottom of the limit block 305, thereby positioning the limit block 305 and the control pressure rod 301; like Figure 1 , Figure 8 and Fig.11As shown, it includes a multi-bin sampling mechanism 6, which is arranged on the outer wall of the control pressure rod 301. The multi-bin sampling mechanism 6 cooperates with the pressing mechanism 3 to control multiple main bodies 1. The multi-bin sampling mechanism 6 also includes a multi-bin connecting frame 601, which is slidably connected to one end of the outer wall of the control pressure rod 301 located outside the main body 1. Two mounting strip holes 605 are set through the top of the multi-bin connecting frame 601, and an opening is set at a place corresponding to the two mounting strip holes 605 on one side of the multi-bin connecting frame 601. The top of the multi-bin connecting frame 601 corresponds to the two mounting strip holes 605. A plurality of groups of engaging grooves 606 are provided at both ends of the multi-bin connection frame 601. A screw rotating frame 602 is rotatably connected to the center of the top of the multi-bin connection frame 601. The outer wall of the screw rotating frame 602 is threadedly connected to the limited position closing frame 603. A sling hook 604 is fixedly connected to the top of the limited position closing frame 603. The circular plate at the top of the control pressure rod 301 is engaged with the engaging groove 606. The bottom of the limited position closing frame 603 is against the circular plate at the top of the control pressure rod 301 connected to the inside of the mounting strip hole 605. The limited position closing frame 603 is connected to the multi-bin connection frame 601 by bolts and nuts. The two main bodies corresponding to each group of engaging grooves 606 are connected. The outer wall of the double-bin connecting strip 607 is detachably connected, and the outer wall of the double-bin connecting strip 607 is fixedly connected with a supporting sheet 608. Through the opening of the multi-bin connecting frame 601 at one end of the two mounting strip holes 605, the control pressure rod 301 can be slid into the inside of the mounting strip hole 605. After the device is moved to the specified position, the circular plate on the top of the control pressure rod 301 is engaged with the engaging groove 606. After the multiple devices are connected to the multi-bin sampling mechanism 6, the screw rod rotating frame 602 is rotated to drive the limit sealing frame 603 to descend and press on the top of each control pressure rod 301 on the multiple devices, and the bolts and nuts are used to fix the control pressure rod 301. The limiting closing frame 603 and the multi-bin connecting frame 601 are tightly connected, and then the double-bin connecting strip 607 is connected to the two opposite main bodies 1 inside the two mounting strip holes 605 by bolts, so that the multi-bin connecting frame 601 and the sampling devices connected to the multi-bin connecting frame 601 can be supported by multiple support plates 608. After multiple devices are installed on the multi-bin connecting frame 601, the slings on mobile transportation tools such as drones and cranes are connected to the sling hooks 604, and the multiple sampling devices connected to the multi-bin connecting frame 601 can be moved as a whole to the designated release waters for sampling.

The two main bodies 1 are connected by bolts, so that the multi-bin connection frame 601 and the sampling devices connected to the multi-bin connection frame 601 can be supported by multiple support sheets 608. After multiple devices are installed on the multi-bin connection frame 601, the slings on mobile transportation tools such as drones and cranes are connected to the sling hooks 604, and the multiple sampling devices connected to the multi-bin connection frame 601 can be moved as a whole to a designated release water area for release and sampling. Therefore, the device can not only sample multiple locations in the water area at the same time, but also can be used separately after the main body 1 is separated from the multi-bin connection frame 601; The control lever 301 is pressed to push the connection block 205 to move downward inside the main body 1, and the connection block 205 is connected to the two opening and closing connection strips 204 by rotation, so that the two opening and closing connection strips 204 are relatively rotated on the connection block 205, so that the opening and closing angles of the two opening and closing connection strips 204 are gradually reduced, so that when the control lever 301 is pressed to descend, the two connection frames 201 can be pulled by the two opening and closing connection strips 204 to rotate around the rotating connection frame 102 as the axis to open the sealing cover 202, and then the two sealing covers 202 can be opened at the same time by pressing, and when multi-bin sampling is performed, after multiple sampling devices are installed on the multi-bin sampling mechanism 6, the sealing cover 202 can be opened by pressing the two opening and closing connection strips 204. By pressing the multi-chamber connecting frame 601, the sealing covers 202 on the horizontal sampling chambers 101 of multiple devices can be opened at one time. In this way, after the sample collection is completed, the collecting vessel can be placed under each horizontal sampling chamber 101, and the sealing covers 202 on multiple horizontal sampling chambers 101 can be opened at one time to allow the sample to flow into the vessel for holding the sample. The samples inside the multiple horizontal sampling chambers 101 can be quickly collected, and the next sampling can be carried out immediately after the samples are collected. After the sealing covers 202 of the multiple sampling devices are opened, the top of the support sheet 608 will be against the bottom of the multi-chamber connecting frame 601, thereby improving the stability of the overall support of the multi-chamber sampling mechanism 6 and the multiple sampling devices.

When the bottom of the right-angled triangle block 106 leaves the bottom inner wall of the limit block 305, the spring force between the bottom of the spring rod 304 and the top inner wall of the slide chamber box 103 and the pulling force of the two tension springs 203 on the two sealing covers 202 quickly reset the control rod 301 and the two sealing covers 202. like Figure 2 , Figure 3 , Figure 6 Figure 7 As shown, the horizontal sampling chamber 101 includes an anti-stuck mechanism 5 arranged inside, and the anti-stuck mechanism 5 includes a blocking connection frame 501, and the blocking connection frame 501 is fixedly connected to the bottom of the control pressure rod 301, and the blocking connection frame 501 slides through the bottom of the main body 1 to the inside of the horizontal sampling chamber 101, and the opposite sides of the blocking connection frame 501 are rotatably connected to the double-headed connecting strips 502 at one end located inside the horizontal sampling chamber 101, and the two double-headed connecting strips 502 are rotatably connected to the anti-stuck frame 503 at one end away from the blocking connection frame 501, and the anti-stuck frame 503 is slidably connected to the inside of the horizontal sampling chamber 101, and the two anti-stuck frames 503 The sides away from each other are fixedly connected with a mosaic closing plate 504, and the mosaic closing plate 504 is mosaicked with the entrance and exit of the horizontal sampling chamber 101. When water flows through the anti-stuck frame 503 and enters the interior of the horizontal sampling chamber 101, the mosaic closing plate 504 is set on the sides away from each other through the two anti-stuck frames 503. When water flows through the anti-stuck frame 503 and enters the interior of the horizontal sampling chamber 101, it will not enter the anti-stuck frame 503 and the horizontal sampling chamber 101 from the position of the mosaic closing plate 504, thereby preventing the water from actively flowing to the end face of the mosaic closing plate 504 with debris when entering the interior of the horizontal sampling chamber 101.

[0031] The working principle of the technical solution provided by the present invention is as follows: When the latch 306 is pressed downward, the stopper 305 is pushed back to slide in the inner part of the inner movable box 105. During this process, a portion of the bottom of the stopper 305 near the slot 306 will abut against the inclined surface of the right-angled triangle block 106. When the slot 306 continues to move downward, the right-angled triangle block 106 will be pushed to slide through the side wall of the inner movable box 105 and stretch the reset spring 108. When the right-angled triangle block 106 completely enters the slot 306, the horizontal sampling chamber 101 is in an open state, and the elasticity of the reset spring 108 will push the right-angled triangle block 106 to reset, so that the bottom of the right-angled triangle block 106 abuts against the inner wall of the bottom of the stopper 305, thereby tightening the stopper 305 and the control rod 30 1. When the sampling device is placed in the designated waters, the electric-controlled retractor 303 automatically contracts after receiving the signal sent by the shore personnel. The upper connecting plate 402 can drive the two lower pressure bars 401 to be pressed down, so that the lower pressure push wheel 404 at the bottom of the lower pressure bar 401 located inside the limit block 305 is against the inclined surface of the right-angled triangle block 106, and the right-angled triangle block 106 is pushed to the position of the bayonet 306. When the bottom of the right-angled triangle block 106 leaves the bottom inner wall of the limit block 305, the spring force between the bottom of the spring rod 304 and the top inner wall of the sliding chamber box 103 and the pulling force of the two tensioning springs 203 on the two sealing covers 202 make the control pressure rod 301 and the two sealing covers 202 quickly reset, thereby sealing the water entering the horizontal sampling chamber 101. When the control pressure rod 301 is lowered to drive the connecting frame 201 and the sealing cover 202 to open the opening of the horizontal sampling chamber 101, the blocking connecting frame 501 is simultaneously pushed down, so that the opening and closing angle between the two double-headed connecting strips 502 gradually increases, and the two embedded sealing plates 504 inside the horizontal sampling chamber 101 can be pushed to move outwards toward the two ends of the horizontal sampling chamber 101. Therefore, when there are many debris in the water area to be sampled, the device can prevent larger debris in the water area from entering the entrance of the horizontal sampling chamber 101 through the anti-stuck frame 503 after entering the water; When water flows through the anti-stuck frame 503 and enters the interior of the horizontal sampling chamber 101, it is affected by the sealing effect of the interlocking sealing plate 504 and the water flow can only enter the interior of the horizontal sampling chamber 101 from the outer wall of the anti-stuck frame 503, thereby preventing the water flow from actively flowing to the end face of the interlocking sealing plate 504 with debris when entering the interior of the horizontal sampling chamber 101, thereby reducing the probability of debris being sandwiched between the interlocking sealing plate 504 and the sealing cover 202 during the sealing process of the horizontal sampling chamber 101 by the sealing cover 202.
