Description

Technical Field

[0001] The present invention relates to the field of surface water monitoring, and in particular to a sampling device based on surface water monitoring. Background Art

[0002] In the existing sampling process of lakes during the freezing period, since the water to be sampled is in a frozen state, it is necessary to drill an annular through-hole in the ice layer by a drilling device, and the inside of the annular through-hole is the icicle to be sampled. However, in this process, since the drilling device drills the ice layer from top to bottom, and the drill teeth of the drilling device drill the annular through-hole in the ice layer by planing, the drill teeth generate high temperature during the planing process. When the drill teeth come into contact with the planed ice chips, some of the ice chips will quickly melt into water, flow down along the icicle, and come into contact with other parts of the icicle, causing the icicle to come into contact with water melted by ice chips at different depths, thereby affecting the subsequent detection of water melted by icicles at different depths;

[0003] Moreover, at the moment when the hole-opening equipment opens the annular hole, the river water under the ice layer will surge upward in an instant and come into contact with the icicle from bottom to top. Then the icicle is affected by the river water under the ice layer, resulting in inaccurate subsequent detection data. Moreover, after the hole-opening equipment opens the annular hole, it is difficult to remove the icicle because it is relatively heavy and has a smooth surface. Summary of the Invention

[0035] The power assembly includes a first moving block 101, a cross mounting plate 102, a first push rod 103, a second push rod 104, an annular fixing frame 105, an annular mounting plate 106, a first gear 107, a motor 108 and a second gear 109; the frame shell 2 is slidably connected to the first moving block 101; the first moving block 101 is fixedly connected to the cross mounting plate 102; a first push rod 103 is fixedly connected to the front and rear sides of the cross mounting plate 102; a first push rod 103 is fixedly connected to the left and right sides of the cross mounting plate 102 The second push rods 104 are provided, and the telescopic parts of the two second push rods 104 are fixedly connected to the first annular push piece 7; the telescopic parts of the two first push rods 103 are fixedly connected to the annular fixing frame 105; the annular fixing frame 105 is rotatably connected to the circular mounting plate 106; the outer side of the circular mounting plate 106 is fixedly connected to the first gear 107; the annular fixing frame 105 is bolted to the motor 108; the output shaft of the motor 108 is fixedly connected to the second gear 109, and the second gear 109 is meshed with the first gear 107.

[0036] The pulling assembly includes a first wire take-up device 201 and a first rope 202 ; the hollow cylinder 3 is bolted to the first wire take-up device 201 , and the other end of the first wire take-up device 201 passes through the hollow cylinder 3 and is fixed to the second annular push piece 8 .

[0037] The specific working of the above embodiment 1 is as follows: It should be noted that the hoisting machine 1 is provided with a battery for powering all the electrical appliances of the device;

[0038] First, manually inject a portion of salt water into the second cavity 6a formed by the cooperation of the hollow cylinder 3, the cylindrical tube 5 and the annular member 6. At this time, since the second annular push piece 8 is located at the bottom of the first cavity 3a, all the second channels 4c are blocked, so the salt water will only flow through the first channel 4b to the inside of the corresponding drill teeth 4 and will not flow. Then, manually put snow into the second cavity 6a. When the snow contacts the salt water, the salt water will accelerate the speed of the snow. In the process of melting into snow water, the snow will absorb the nearby heat. Then, the frame shell 2, The hollow cylinder 3, the drill teeth 4, the cylindrical tube 5, the circular ring 6, the first annular push piece 7, the second annular push piece 8, the power assembly and the pulling assembly are placed at the position where the icicles need to be removed. Then, the telescopic parts of the two first push rods 103 simultaneously push the annular fixing frame 105 and the parts connected to the annular fixing frame 105 to move downward. At the same time, the motor 108 drives the first gear 107, the annular mounting plate 106 and the parts connected to the annular mounting plate 106 to rotate through the second gear 109, thereby drilling an annular through hole in the ice layer in a planing manner through the drill teeth 4;

[0039] It should be noted that, when the drill teeth 4 drill an annular through hole in the ice layer, the two second push rods 104 extend their telescopic parts at the same time to push the first annular push piece 7 downward, and then move downward in the second cavity 6a. At the same time, all the first wire take-ups 201 pull the second annular push piece 8 upward through the corresponding first ropes 202. In this process, Figure 11 As shown, the first annular push piece 7 will push the snow water to flow downward, while the second annular push piece 8 will suck the snow water to flow upward, forming positive and negative pressure, so that the snow water can flow through the first channel 4b and the second channel 4c in sequence, and then flow into the first cavity 3a. In the process of the snow water flowing from the first channel 4b into the corresponding drill tooth 4 and then flowing out from the second channel 4c, the snow water will cool the drill tooth 4. In this way, the drill tooth 4 is cooled by absorbing the nearby heat when the snow water melts, so as to avoid the drill tooth 4 from generating high temperature during the planing process. When the drill tooth 4 contacts the planed ice chips, part of the ice chips will quickly melt into water, flow downward along the icicle, and contact other parts of the icicle, thereby affecting the subsequent detection of the water melted from icicles at different depths, and the snow water inside the drill tooth 4 is replaced by flowing to avoid the drill tooth 4 being unable to continue to cool down when the snow water absorbs enough heat.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1-2 and Figure 5-7As shown, it also includes an ice chip extraction component; the ice chip extraction component includes an ice chip extraction pipe 301, a first annular pipe 302, a pump 303, a second annular pipe 304 and an ice chip outlet pipe 305; the outer surface of the hollow cylinder 3 is bolted to the pump 303; the hollow cylinder 3 is bolted to the first annular pipe 302, and the first annular pipe 302 is connected to the feed pipe of the pump 303; the hollow cylinder 3 is bolted to the second annular pipe 304, and the second annular pipe 305 is connected to the feed pipe of the pump 303; the hollow cylinder 3 is bolted to the second annular pipe 304, and the second annular pipe 305 is connected to the feed pipe of the pump 303. The second annular tube 304 is connected to the discharge pipe of the pump 303, and the second annular tube 304 is located above the first annular tube 302; the hollow cylinder 3 is fixed with ten ice chip extraction tubes 301, and the other ends of all ice chip extraction tubes 301 pass through the hollow cylinder 3 and are connected to the first annular tube 302; the second annular tube 304 is connected to ten ice chip discharge tubes 305, and the other ends of the ice chip discharge tubes 305 pass through the hollow cylinder 3 and are connected to the second cavity 6a.

[0042] Each drill tooth 4 is provided with a plurality of convex teeth 4a, and the plurality of convex teeth 4a provided on each two adjacent drill teeth 4 are staggered; therefore, in the process of the drill tooth 4 drilling an annular through hole on the ice layer, the ice chips shaved out are relatively fine, and can better pass through the ice chip extraction tube 301, preventing the ice chips from being too large and getting stuck in the ice chip extraction tube 301.

[0043] The specific operation of the above embodiment 2 is as follows: It should be noted that, if Figure 7 As shown, in the process of the drill teeth 4 drilling an annular through hole in the ice layer in a planing manner, the pump 303 is started to allow the ice chips planed by the drill teeth 4 to be sucked into the first annular tube 302 through all the ice chip extraction tubes 301, and then pumped into the pump 303 through the feed port of the pump 303, and then discharged from the discharge port of the pump 303, so as to realize the transfer of the ice chips planed by the drill teeth 4, and avoid the ice chips being stuck between two adjacent drill teeth 4, causing the drill teeth 4 to malfunction. It should be noted that the ice chips discharged from the discharge port of the pump 303 will pass through the second annular tube 304 and the ice chip discharge tube 305 in turn, and be discharged into the second cavity 6a. At this time, the first When the annular push piece 7 slides downward in the second cavity 6a, the ice chips will be on the upper surface of the first annular push piece 7. After the drill teeth 4 drill an annular through hole in the ice layer, the ice chips in the second cavity 6a form an isolation layer to keep the icicle warm and prevent the water generated when the icicle melts from flowing downward and contacting other parts of the icicle. Moreover, since each drill tooth 4 is provided with a plurality of convex teeth 4a, and the plurality of convex teeth 4a provided on each two adjacent drill teeth 4 are staggered, the ice chips shaved out in the process of the drill teeth 4 drilling the annular through hole in the ice layer are relatively fine, and can better pass through the ice chip extraction tube 301, preventing the ice chips from being too large and getting stuck in the ice chip extraction tube 301.

[0044] Example 3

[0045] On the basis of Example 2, Figure 1-2、 Figure 5-10 and Figure 12-13 As shown, it also includes an edge fitting component; the edge fitting component includes an elastic member 401, a T-shaped mounting plate 402 and a flexible card plate 403; the second annular push piece 8 is fixedly connected to five elastic members 401 for pushing the second annular push piece 8 to move downward, and the elastic member 401 is fixedly connected to the hollow cylinder 3; the first annular push piece 7 is bolted to three T-shaped mounting plates 402; each T-shaped mounting plate 402 is fixedly connected to a flexible card plate 403 for clamping icicles.

[0046] The bottom of the flexible card board 403 is provided with an inclined portion 403a for guiding the flexible card board 403. The inclined portion 403a guides the flexible card board 403 to prevent the flexible card board 403 from being unable to be inserted between the icicle and the cylindrical tube 5 due to the relatively small gap between the two.

[0047] Several triangular blocks are provided on the side of the flexible card board 403 close to the icicle, and the triangular blocks are tilted upward. The sharp points of the triangular blocks pierce the surface of the icicle to clamp the icicle, thereby preventing the flexible card board 403 from being unable to fix the icicle due to insufficient friction between the smooth surface of the icicle and the flexible card board 403, causing the icicle to move downward and come into contact with the river water.

[0048] It also includes a wrapping component; the wrapping component includes a second wire take-up device 501, a second rope 502 and a limiting block 503; the hollow cylinder 3 is fixed with two limiting blocks 503 symmetrically distributed front and back; the hollow cylinder 3 is bolted with two second wire take-ups symmetrically distributed front and back; the two second wire take-ups 501 are commonly connected with two second ropes symmetrically distributed left and right, and both ends of the second rope 502 pass through the corresponding limiting blocks 503 and the hollow cylinder 3.

[0049] The circular ring 6 is made of a flexible material, and its lower part can expand into a tray shape to support the icicle and move it upward away from the ice layer to avoid the icicle being difficult to remove due to its relatively heavy weight and smooth surface.

[0050] The specific operation of the above embodiment 3 is as follows: It should be noted that, during the process in which the first wire take-up device 201 pulls the second annular push piece 8 upwards through the first rope 202 , the elastic member 401 is in a compressed state;

[0051] It should be noted that, when the drill teeth 4 drill an annular through hole in the ice layer, the first annular push piece 7 slides downward in the second cavity 6a, which drives the T-shaped mounting plate 402 and the flexible card plate 403 to move downward together. During the movement, the flexible card plate 403 is stuck in the gap between the ice column and the cylindrical tube 5. Since the bottom of the flexible card plate 403 is provided with a tilting portion 403a for guiding the flexible card plate 403, the tilting portion 403a guides the flexible card plate 403, preventing the flexible card plate 403 from being unable to be inserted between the ice column and the cylindrical tube 5 due to the relatively small gap between the two.

[0052] When the distance sensor set inside the drill tooth 4 senses that the drill tooth 4 is still a little distance away from the bottom of the ice layer, the distance sensor transmits the information to the controller, and then the controller controls the motor 108, the pump 303, the first push rod 103 and the second push rod 104 to stop working. At this time, Figure 12 As shown, the first annular push piece 7 is located above the circular ring member 6, and the second annular push piece 8 is located above the first cavity 3a. Then all the first wire take-ups 201 loosen the first rope 202 at the same time. At this time, the second annular push piece 8 moves downward under the push of the elastic member 401, pushing the snow water to flow. The snow water passes through the second channel 4c and the first channel 4b in turn from the first cavity 3a, and then flows back to the second cavity 6a. At this time, since the first annular push piece 7 is located above the circular ring member 6, it will block the snow water. The thrust of the second annular push piece 8 to push the snow water to flow will push the circular ring member 6 to fit the icicle, and then pass through the two first push rods. The telescopic part 103 extends again to push the annular fixing frame 105 and the parts connected to the annular fixing frame 105 downward, so that the drill teeth 4 can pierce the last connection between the ice layer and the icicle. During this piercing process, since all the flexible card plates 403 cooperate with each other to fix the icicle, the icicle will not move downward and come into contact with the river water. In addition, a plurality of triangular card blocks are provided on the side of the flexible card plate 403 close to the icicle, and the triangular card blocks are tilted upward. The sharp points of the triangular card blocks pierce the surface of the icicle to clamp the icicle, which can better fix the icicle and prevent the icicle from moving downward due to insufficient friction between the smooth surface of the icicle and the flexible card plate 403.

[0053] In the process of the drill tooth 4 piercing the last connection between the ice layer and the icicle, at this time, the circular ring member 6 is fitted with the icicle under the push of snow water, and all the flexible card plates 403 cooperate with each other to fix the icicle and prevent the icicle from moving downward. In the process of the drill tooth 4 piercing the last connection between the ice layer and the icicle, the circular ring member 6 slides downward on the outer surface of the icicle in a fitting manner. At the moment when the drill tooth 4 pierces the last connection between the ice layer and the icicle, the river water is restricted by the circular ring member 6 and cannot surge upward through the annular through hole and contact the icicle, thereby avoiding the river water surging up through the annular through hole and contacting the icicle at the moment when the drill tooth 4 pierces the last connection between the ice layer and the icicle, resulting in inaccurate subsequent detection data.

[0054] It should be noted that after the drill teeth 4 pierce the last connection point between the ice layer and the icicle, the sampling icicle 100 is located above the circular ring 6. Figure 13 As shown, the two second ropes 502 are then tightened simultaneously by the two second take-ups 501. During the tightening process, the second ropes 502 are restricted by the restriction blocks 503, which pull the two sides of the circular ring 6 toward the middle. Then, the hoisting machine 1 drives the frame shell 2 and the parts connected to the frame shell 2 to move upward and away from the ice layer. During the moving away process, the two sides of the circular ring 6 move toward the middle to form a tray, which supports the sampling icicle 100 and moves it upward and away from the ice layer, thereby preventing the sampling icicle 100 from being difficult to remove due to its relatively heavy weight and smooth surface.

[0055] It should be noted that after the two sides of the circular ring member 6 move closer to the middle, two cavities will be formed. At this time, the second annular push piece 8 will continue to push the snow water to flow under the push of the elastic member 401. At this time, the first annular push piece 7 is still located above the circular ring member 6, and the snow water fills the two cavities formed by the circular ring member 6. At this time, the snow water in the two cavities formed by the circular ring member 6 will form an isolation layer to keep the sampling icicle 100 warm.

[0057] On the basis of Example 3, Figure 1-4As shown, it also includes a snow transfer assembly; the snow transfer assembly includes a second moving block 601, a bearing plate 602, a third push rod 603, a U-shaped mounting plate 604, an annular mounting plate 605, an L-shaped mounting plate 606, a flexible arc plate 607 and a fourth push rod 608; the frame shell 2 is slidingly connected to the second moving block 601; the second moving block 601 is fixed to the bearing plate 602; the bearing plate 602 is bolted to two third push rods 603; the telescopic parts of the two third push rods 603 are commonly fixed to the U-shaped mounting plate 604; the U-shaped mounting plate 604 is fixed to the annular mounting plate 605; the annular mounting plate 605 is fixed to four L-shaped mounting plates 606; a flexible arc plate 607 for spreading the snow is commonly fixed between each two adjacent L-shaped mounting plates 606; the annular mounting plate 605 is fixed to four third push rods 603, and the telescopic parts of the third push rods 603 are fixed to the corresponding flexible arc plates 607.

[0058] The annular mounting plate 605 cooperates with the four flexible arc plates 607 to form a snow-binding groove 606a, and the snow-binding groove 606a has the same size as the channel of the second cavity 6a, so that snow can be transferred to the second cavity 6a through the snow-binding groove 606a without the need to manually transfer the snow to the second cavity 6a.

[0059] The specific operation of the above-mentioned embodiment 4 is as follows: It should be noted that when the hoisting machine 1 places the frame shell 2 and the parts connected to the frame shell 2 to the position where the icicles need to be removed, the telescopic portion of the fourth push rod 608 is extended, and the midpoint of the flexible arc plate 607 is used as the pushing point to push the corresponding flexible arc plates 607 closer to each other. At this time, the four flexible arc plates 607 are fitted together, presenting the following Figure 3 In the state shown, the telescopic parts of the two third push rods 603 are extended to push the U-shaped mounting plate 604 and the parts connected to the U-shaped mounting plate 604 to move downward. When the annular mounting plate 605 contacts the ice layer, the telescopic part of the third push rod 603 stops extending, and then the four fourth push rods 608 drive the telescopic part to retract and drive the corresponding flexible arc plate 607 to recover. During the recovery process, the four flexible arc plates 607 cooperate with each other to push the snow on the inside of the annular mounting plate 605 and contact the annular mounting plate 605. During this pushing process, the snow will continue to compress and then be compressed in the snow-holding groove 606a formed by the cooperation between the annular mounting plate 605 and the four flexible arc plates 607. In this way, the snow on the upper surface of the icicle part to be removed is removed by pushing, so as to avoid the melted water from the snow flowing down along the side of the icicle during the icicle removal process, causing the snow water to adhere to the surface of the icicle, affecting the subsequent detection effect.

[0060] Then, the two third push rods 603 drive the U-shaped mounting plate 604 and the parts connected to the U-shaped mounting plate 604 to move upward and away from the ice layer, and the snow compressed in the snow-binding groove 606a is restricted by the cooperation between the annular mounting plate 605 and the flexible arc plate 607, and will move together. Then, first control the first moving block 101 to drive the cross mounting plate 102 and the parts connected to the cross mounting plate 102 to move forward. When the annular mounting plate 605 is located in the middle of the first annular push piece 7 and the annular fixing frame 105, at this time, the snow-binding groove 606a is located directly above the second cavity 6a, and then the third push rod 603 is extended and retracted. The fourth push rod 608 is extended again to push the U-shaped mounting plate 604 and the parts connected to the U-shaped mounting plate 604 downward, so that the annular mounting plate 605 contacts the hollow cylinder 3 and the flexible arc plate 607 contacts the cylindrical tube 5. At this time, the snow-binding groove 606a coincides with the second cavity 6a, and then the telescopic part of the four fourth push rods 608 is controlled to extend again, pushing the flexible arc plate 607 to release the restriction on the snow compressed in the snow-binding groove 606a. It should be noted that since the snow-binding groove 606a and the second cavity 6a have the same channel size, the compressed snow will fall directly into the second cavity 6a, and there is no need to manually transfer the snow to the second cavity 6a.

[0061] It should be noted that the first push rod 103 , the second push rod 104 , the third push rod 603 and the fourth push rod 608 are all multi-section push rods.
