[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1 to 8, A hydrographic survey sampling device with an ice melting mechanism, including sampling cylinders 1. There are multiple sampling cylinders 1. A connecting piece for mutual connection is connected to the sampling cylinder 1. The connecting piece includes a connecting top ring 101 and a connecting bottom ring 102. The connecting top ring 101 is fixedly sleeved on the top end of the sampling cylinder 1, and the connecting bottom ring 102 is fixedly sleeved on the bottom end of the sampling cylinder 1. A hook 103 is connected to the bottom end of the connecting top ring 101 through a chain. A ring opening matching the hook 103 is opened on the connecting bottom ring 102. By hanging the hook 103 on the ring opening, the connecting bottom ring 102 and the connecting top ring 101 can be connected, thereby connecting the sampling cylinders 1. Multiple sampling cylinders 1 are connected in sequence. The distance between two adjacent sampling cylinders 1 can be controlled by controlling the length of the chain, thereby adjusting the sampling depth. The sampling cylinder 1 at the top is hung with a rope or a chain through the hook 103, and multiple sampling cylinders 1 can be sunk into the water for sampling. It also includes a protective cover cylinder 2, an ice melting mechanism, a stabilizing cylinder 4, and a sampling mechanism. Compared with the method of manually chiseling for sampling under ice in the prior art, in the present invention, a drill bit 301 that can be heated is provided to automatically drill holes in the ice surface. The stability of the sampling device is ensured by the vacuum suction cup 201. The drill hole is stabilized by the stabilizing cylinder 4 to reduce the re-freezing of water in the drill hole. Multiple sampling cylinders 1 are connected by the connecting piece. The water is sucked into the sampling cylinder 1 by the cooperation of the draw plate 401 and the blow-suction dual-purpose air pump 402 to sample water at different depths.

[0046] An adsorbing component for adsorbing on the ice surface is installed on the protective cover cylinder 2. A sampling opening for the sampling cylinder 1 to pass through is opened at the top of the protective cover cylinder 2. The adsorbing component includes a vacuum suction cup 201. The vacuum suction cup 201 is installed at the bottom of the protective cover cylinder 2. The vacuum suction cup 201 can be sucked and adsorbed on the ice surface by the blow-suction dual-purpose air pump 402. The bottom of the vacuum suction cup 201 is in close contact with the ice surface. The vacuum suction cup 201 is communicated with the blow-suction dual-purpose air pump 402. By sucking air into the vacuum suction cup 201 by the blow-suction dual-purpose air pump 402, the vacuum suction cup 201 is evacuated and tightly adsorbed on the ice surface, reducing the movement of the protective cover cylinder 2, thereby ensuring the stability of subsequent drilling and sampling. The vacuum suction cup 201 is rotationally communicated with an air extraction seat 203 through an adjusting rod 202. Multiple air extraction seats 203 are communicated with each other through a hose. One of the hoses is communicated with the blow-suction dual-purpose air pump 402 through an air extraction pipe 204. A valve 205 is installed on the air extraction pipe 204. The outside of the adjusting rod 202 is provided with threads, and the adjusting rod 202 is threadedly connected to the protective cover cylinder 2. Rotating the adjusting rod 202 can adjust the height of the vacuum suction cup 201 to a certain extent, facilitating better close contact between the vacuum suction cup 201 and the ice surface. The hose can adapt to the lifting of the vacuum suction cup 201. After the blow-suction dual-purpose air pump 402 sucks air into the vacuum suction cup 201 and it is tightly adsorbed on the ice surface, the air extraction pipe 204 is closed by the valve 205 to ensure the stability of the vacuum suction cup 201.

[0047] The ice melting mechanism can move below the sampling port to drill and heat the ice surface. The ice melting mechanism includes a drill bit 301, which is movably arranged inside a protective cover cylinder 2. A heat-conducting liquid is contained inside the drill bit 301, and a heater 302 for heating the heat-conducting liquid is installed inside the drill bit 301. The drill bit 301 can move up and down to drill into the ice surface. An electric cylinder 303 is installed inside the protective cover cylinder 2, and an electric cylinder 304 is installed at the output end of the electric cylinder 303. The electric cylinder 303 moves horizontally, and the electric cylinder 304 moves vertically. A motor 305 is installed at the output end of the electric cylinder 304, and the drill bit 301 is fixedly installed at the output end of the motor 305. The drill bit 301 can be moved to the center position of the protective cover cylinder 2, that is, the position corresponding to the sampling port, by the electric cylinder 303. The drill bit 301 is driven to rotate by the motor 305, and the drill bit 301 is driven to descend by the electric cylinder 304, so as to drill the ice surface through the drill bit 301. The inside of the drill bit 301 is a cavity, and a storage battery is installed inside the drill bit 301 to supply power to the heater 302. The heater 302 heats the heat-conducting liquid inside the drill bit 301. As the drill bit 301 rotates, the heat-conducting liquid flows inside the drill bit 301, expanding the contact with the peripheral wall of the drill bit 301, so as to better heat the drill bit 301, facilitate the melting of the ice surface during the drilling process, improve the opening efficiency. At the same time, a baffle is fixedly connected inside the drill bit 301 to isolate the storage battery and the heat-conducting liquid, avoiding damage to the storage battery caused by the heat-conducting liquid.

[0048] To concentrate the heat, a sealing ring 3 is fixedly connected to the bottom end of the protective cover cylinder 2, and the sealing ring 3 abuts against the ice surface. When the blow-suction dual-purpose air pump 402 sucks air into the vacuum sucker 201 to fix the protective cover cylinder 2 on the ice surface, the sealing ring 3 seals the gap between the protective cover cylinder 2 and the ice surface, reducing the entry of external cold air into the inside of the protective cover cylinder 2, thereby reducing the loss of heat dissipated by the drill bit 301, and making the inside of the protective cover cylinder 2 in a relatively high temperature environment. The bottom end of the protective cover cylinder 2 is a disc shape with a relatively large area, reducing the pressure on the ice surface, so as to avoid the rupture of the ice surface caused by pressure during the ice melting and drilling process.

[0049] The stabilizing cylinder 4 and the ice melting mechanism move synchronously. A second heater is installed on the stabilizing cylinder 4. The stabilizing cylinder 4 can move and descend to the opening after drilling is completed to block the ice water. The output end of the first electric cylinder is equipped with a third electric cylinder 6. The stabilizing cylinder 4 is fixedly installed at the output end of the third electric cylinder 6. The third electric cylinder 6 moves vertically. The first electric cylinder 303 drives the drill bit 301 and the stabilizing cylinder to move synchronously. When the drill bit 301 is at the drilling position, the stabilizing cylinder is away from the drilling. After drilling is completed, the second electric cylinder 304 drives the drill bit 301 to rise above the ice surface. The first electric cylinder 303 drives the stabilizing cylinder to move to the drilling position, and at the same time the drill bit 301 is away from the drilling. The third electric cylinder 6 drives the stabilizing cylinder to move downward until it contacts the hole wall of the drilled ice hole, isolating the ice surface and the water in the drilling. The stabilizing cylinder is heated by the second heater, thereby heating the water in the drilling, reducing the obstruction caused by the refreezing of the water in the drilling to the lifting of the sampling cylinder 1. The outer wall dimensions of the drill bit 301 and the stabilizing cylinder are adapted, and the diameters of the drill bit 301 and the stabilizing cylinder are larger than the diameter of the sampling cylinder 1. The sampling cylinder 1 can pass through the stabilizing cylinder and enter the water for sampling.

[0050] The sampling mechanism is used to suck the water sample into the sampling tube 1. The sampling mechanism includes a pull-out plate 401 and a blowing and sucking dual-purpose air pump 402. The pull-out plate 401 is sealingly and slidably arranged inside the sampling tube 1. The blowing and sucking dual-purpose air pump 402 is used to draw a vacuum above the pull-out plate 401 to drive the pull-out plate 401 to rise and suck the water sample into the sampling tube 1. In order to prevent the pull-out plate 401 from falling from the sampling tube 1, the bottom end of the sampling tube 1 is connected to a limiting ring 403 for limiting the pull-out plate 401. At the same time, the limiting ring 403 can reduce the bottom opening of the sampling tube 1. The top of the sampling tube 1 is connected with a three-way joint 404, and two adjacent three-way joints 404 are connected through a connecting pipe 405. The three-way joint 404 at the top is connected with the suction port of the blowing and suction dual-purpose air pump 402, and the bottom of the three-way joint 404 at the bottom is connected with a plug 406. The ends of the three-way joint 404 and the connecting pipe 405 can be set as threads, and the connecting pipe 405 can be connected through the threads. The pipe 405 is connected to the three-way joint 404, and the plug 406 is also connected to the bottom end of the three-way joint 404 at the bottom through a threaded connection to seal, so that multiple sampling tubes 1 are connected to the dual-purpose air pump 402 for blowing and sucking. The sampling tubes 1 are connected in advance through the hook 103 and the ring mouth, and two adjacent sampling tubes 1 are connected through the connecting pipe 405. In the process of lowering the sampling tube 1 into the water, the dual-purpose air pump 402 is used to blow air into the interior of the sampling tube 1, so that the pull-out plate 401 is located below the sampling tube 1 and the limit ring 40 3, the limit ring 403 limits the pull-out plate 401 to prevent it from escaping from the sampling tube 1. The limit ring 403 has a heavy weight, so that the sampling tube 1 is in a stable vertical state in the water. When the sampling tube 1 descends to a suitable depth, the blowing and suction dual-purpose air pump 402 sucks air into the sampling tube 1, and the air pressure above the pull-out plate 401 decreases. Under the action of the higher pressure in the water, the pull-out plate 401 rises to quickly suck the water at the sampling tube 1 into the interior of the sampling tube 1 for collection, and then the sampling tube 1 is pulled out of the water to collect the water sample inside it.

[0051] The working principle or use process of the hydrological survey sampling device with an ice melting mechanism is as follows: the device is placed at the position to be sampled on the ice surface, the ice surface is flattened in advance, and then the adjustment rod 202 is rotated to make the vacuum suction cup 201 close to the ice surface, and the suction pipe 204 is opened through the valve 205. The dual-purpose air pump 402 sucks air into the vacuum suction cup 201 to fix the protective cover tube 2 on the ice surface, and then the valve 205 is closed, and the electric cylinder 1 303 drives the drill bit 301 to move to the bottom of the sampling port, the motor 305 drives the drill bit 301 to rotate, and the electric cylinder 2 304 drives the drill bit 301 to descend to drill a hole in the ice surface, and at the same time, the heater 1 302 heats the drill bit 301 to assist in melting the ice and opening the hole;

[0052] After the drilling is completed, the second electric cylinder 304 drives the drill bit 301 to rise. Then, the first electric cylinder 303 drives the stabilizing cylinder 4 to move to the drilling position. The third electric cylinder 6 drives the stabilizing cylinder 4 to descend into the drilling hole and contact the hole wall. The second heater 5 heats the stabilizing cylinder 4 to prevent the water in the drilling hole from freezing again.

[0053] According to the need of the sampling depth, select an appropriate number of sampling cylinders 1. At the same time, adjust the length of the chain, and lower the sampling cylinders 1 through the sampling port and the drilling hole to underwater in sequence. During the descent, the blow-suction air pump 402 blows air into the sampling cylinder 1, so that the pull plate 401 is at the bottom of the sampling cylinder 1. After descending to an appropriate depth, the blow-suction air pump 402 sucks air into the sampling cylinder 1, so that the pull plate 401 quickly rises to suck the water at the corresponding depth into the interior of the sampling cylinder 1.

[0054] Lift the sampling cylinder 1 above the water surface and take it out from the sampling port. The blow-suction air pump 402 blows air into the sampling cylinder 1 to make the pull plate 401 move downward, collect the water sample in the sampling cylinder 1 and conduct subsequent detection. The third electric cylinder 6 drives the stabilizing cylinder 4 to move out of the drilling hole. Open the air extraction pipe 204 through the valve 205. The blow-suction air pump 402 blows air into the vacuum suction cup 201 through the air extraction pipe 204 to release the fixation of the protective cover cylinder 2, and then move the hydrographic survey sampling device with the ice melting mechanism.
