DETAILED DESCRIPTION

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

[0025] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: an unmanned hydrological monitoring boat for coal mine water control, comprising a sealed hull shell 1. The hull shell 1 adopts a sealed design to ensure that the internal components will not be damaged by water ingress. An engine assembly 2 is fixedly installed on the rear side of the lower part of the outer surface of the hull shell 1. A propeller 3 is provided at the output end of the engine assembly 2. The engine assembly 2 and the propeller 3 are in the prior art. A user can remotely operate the engine assembly 2 to control the propeller 3, thereby changing the direction of the propeller 3 to control the movement of the hull shell 1 in the water. A lifting mechanism 4 is provided at the rear part of the inner cavity of the hull shell 1. The lifting mechanism 4 is used to control the buoyancy and sinking of the unmanned boat to obtain water samples at different depths. A sampling mechanism 5 is provided at the front part of the inner cavity of the hull shell 1 for collecting water samples when the unmanned boat reaches a suitable position.

[0026] In order to control the floating and sinking of the unmanned boat in the water, Figure 2 and Figure 3 As shown, the lifting mechanism 4 includes a mounting frame 41 fixedly mounted in the middle of the inner cavity of the hull shell 1, a first motor 42 is mounted on the inner surface of the mounting frame 41, an output end of the first motor 42 is fixedly connected to a first gear 43, and a plurality of connecting blocks 46 in a circumferential array are also fixedly connected to the middle of the inner cavity of the hull shell 1, the rear ends of the plurality of connecting blocks 46 are rotatably connected to external gear rings 47, the plurality of external gear rings 47 are all meshed with the first gear 43, the inner surfaces of the plurality of external gear rings 47 are all threadedly connected to hollow threaded rods 48, the inner surfaces of the plurality of hollow threaded rods 48 are all slidably connected to guide rods 49, and the front ends of the plurality of guide rods 49 are all fixedly connected to the inner surface of the hull shell 1. Therefore, when the first motor 42 is working, it will drive the first gear 43 to rotate continuously, and the first gear 43 will drive the plurality of external gear rings 47 to rotate simultaneously, so that the hollow threaded rods 48 threadedly connected to the inner surfaces of the plurality of external gear rings 47 move forward or backward along the guide rods 49 at the same time.

[0027] Furthermore, water storage cylinders 44 are fixedly installed at positions corresponding to the plurality of connection blocks 46 on the inner cavity rear wall of the hull shell 1, and the rear ends of the plurality of water storage cylinders 44 are fixedly connected to water diversion pipes 45 connected to the outer surface of the hull shell 1, and the inner surfaces of the plurality of water storage cylinders 44 are slidably connected to pistons 410, and the front ends of the plurality of pistons 410 are fixedly connected to the corresponding hollow threaded rods 48. In the initial state, the pistons 410 are located at the rear of the corresponding water storage cylinders 44, and at this time, most of the inner cavity of the hull shell 1 is air, so that the unmanned boat is The body density is less than that of water, and it will float on the water surface. The user can move the position of the unmanned boat on the water surface by controlling the propeller 3. Then, when the first motor 42 is working, multiple hollow threaded rods 48 will move forward at the same time, causing the hollow threaded rods 48 to pull the piston 410 forward, and the external water will enter the part behind the piston 410 in the water storage cylinder 44 through the water diversion pipe 45, increasing the overall density of the hull shell 1, allowing the unmanned boat to gradually sink, and when it sinks to a suitable depth, the sampling mechanism 5 will work to collect water samples.

[0028] In order to collect water samples when the unmanned vessel reaches a suitable location, Figure 4 and Figure 5 As shown, the sampling mechanism 5 includes two connecting rods 52 fixedly mounted on the upper front side of the inner surface of the hull 1, the lower ends of the two connecting rods 52 are commonly fixedly connected to a second motor 51, and the output end of the second motor 51 is fixedly connected to a toothless gear 53, so when the second motor 51 is working, it will drive the toothless gear 53 to rotate.

[0029] Specifically, a plurality of mounting rods 54 are fixedly installed on the lower side of the front inner cavity of the hull 1, and a winding drum 55 is rotatably installed at the rear ends of the plurality of mounting rods 54, and a second gear 57 is fixedly connected to the rear ends of the plurality of winding drums 55, and the plurality of second gears 57 are adapted to the gear tooth portion of the toothless gear 53. Therefore, when the gear tooth portion of the toothless gear 53 passes through the corresponding second gear 57, it will drive the corresponding second gear 57 to rotate, thereby driving the winding drum 55 to rotate.

[0030] It should be noted that the gear tooth width of the toothless gear 53 will only drive one of the second gears 57 to rotate, and will not contact the two second gears 57 at the same time.

[0031] Furthermore, a plurality of sampling barrels 58 are fixedly installed on the front part of the inner cavity of the hull shell 1, and the plurality of sampling barrels 58 are all located at the rear side of the corresponding mounting rods 54, and the open ends of the plurality of sampling barrels 58 all penetrate the outer surface of the hull shell 1, and the inner surfaces of the plurality of sampling barrels 58 are all provided with rubber sleeves 59, and the inner surfaces of the plurality of rubber sleeves 59 are all provided with samplers 6, and the rubber sleeves 59 are fixed to the sampling barrels 58, and the rubber sleeves 59 can ensure the sealing when the samplers 6 enter the interior thereof, and springs 511 are provided between the upper ends of the plurality of samplers 6 and the corresponding upper walls of the inner cavities of the rubber sleeves 59, and the outer surfaces of the plurality of winding drums 55 are all wound with steel wire ropes 56, and the starting ends of the plurality of steel wire ropes 56 are connected to the winding drums 55. The wire drum 55 is fixedly connected, and the tail ends of multiple steel wire ropes 56 all pass through the upper ends of the corresponding sampling tubes 58 and are connected to the upper ends of the corresponding samplers 6. Therefore, when the toothless gear 53 rotates forward, the gear tooth portion of the toothless gear 53 drives the corresponding second gear 57 to rotate, and the second gear 57 drives the winding drum 55 to rotate and pull the steel wire rope 56, so that the steel wire rope 56 applies an upward pulling force to the sampler 6 until the sampler 6 is received in the rubber sleeve 59. When the toothless gear 53 rotates in the opposite direction, it will move the second gear 57 that has been rotated before, and release the steel wire rope 56 wrapped around the surface of the winding drum 55, so that the sampler 6 is pushed out of the rubber sleeve 59 by the elastic force of the spring 511.

[0032] In addition, a pad strip 510 is provided on the side of the outer surface of the toothless gear 53 away from the multiple winding reels 55. The thickness of the pad strip 510 is lower than the thickness of the teeth on the outer surface of the toothless gear 53, so that when the tooth portion of the toothless gear 53 completely passes through a winding reel 55, the corresponding sampler 6 will completely enter the corresponding rubber sleeve 59, and the subsequent pad strip 510 will press against the winding reel 55, thereby preventing the winding reel 55 from continuing to rotate or returning to the initial position due to the elastic force of the spring 511, so each sampling only requires the toothless gear 53 to rotate forward a certain angle.

[0033] In addition, the sampler 6 is cylindrical in shape, and the middle part of the outer surface of the sampler 6 is hollowed out. When the sampler 6 is completely located outside the hull 1, the hollow part in the middle of the sampler 6 will be exposed in the water, and when the sampler 6 is folded, the cylinder at the end of the sampler 6 will block the opening part of the rubber sleeve 59, so that when the sampler 6 is retracted into the rubber sleeve 59, it will collect water samples of the corresponding depth to which the unmanned boat dives.

[0034] The working principle of the utility model is as follows: when the first motor 42 is working, the first gear 43 is driven to rotate continuously, and the first gear 43 drives multiple outer gear rings 47 to rotate simultaneously, so that the hollow threaded rods 48 threadedly connected to the inner surfaces of the multiple outer gear rings 47 move forward or backward along the guide rod 49 at the same time, thereby moving the position of the piston 410 in the water storage cylinder 44, thereby controlling the amount of external water entering the water storage cylinder 44 from the water diversion pipe 45, and then controlling the overall density inside the hull 1, so that the unmanned boat can be controlled to float or sink, and collect water samples at a suitable depth through the operation of the sampling mechanism 5;

[0035] In the unmanned boat, the second motor 51 drives the toothless gear 53 to rotate when it is working. When the toothless gear 53 rotates forward, the gear teeth of the toothless gear 53 drives the corresponding second gear 57 to rotate. The second gear 57 drives the winding drum 55 to rotate and pull the wire rope 56, so that the wire rope 56 applies an upward pulling force to the sampler 6 until the sampler 6 is put into the rubber sleeve 59. When the sampler 6 is put into the rubber sleeve 59, the water sample corresponding to the depth to which the unmanned boat dives will be collected;

[0036] When the toothless gear 53 of the unmanned boat rotates in the opposite direction, it will move the second gear 57 that has been rotated before, release the wire rope 56 wrapped around the surface of the winding drum 55, and make the sampler 6 be pushed out of the rubber sleeve 59 by the elastic force of the spring 511. At this time, the user can use the container to obtain the collected water sample below.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
