Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampler technology, specifically to a fishing rod-type electric water quality sampler. Background Technology
[0002] Water sampling mainly involves collecting water samples from water bodies for laboratory analysis.
[0003] Chinese patent CN208721443U discloses a fishing rod-type long-distance water sampler. One end of the fishing line passes through the float and connects to the upper and lower covers of the water sampler. The other end of the fishing line is mounted on a pneumatic component to complete the long-distance casting of the water sampler. This enables precise casting and retrieval of the water sampler in areas far from the shore or where direct human contact with the water surface is impossible, improving the convenience, safety, and practicality of sampling.
[0004] However, its applicable environment is still limited to open waters where the water surface is not frozen and the sampling path is unobstructed. In winter low-temperature environments or frozen waters, the sampler cannot directly contact the water due to the obstruction of the ice layer, resulting in the device being unable to complete effective sampling. The fundamental reason is that this type of device lacks an ice-breaking structure and cannot achieve physical penetration and thermal melting of the ice layer in a coordinated manner. Therefore, once the ice layer is thick or the ice surface is smooth and hard, even if the sampler is accurately thrown to the target location, it cannot break through the ice layer to contact the water, thus losing the sampling function. In addition, since the fishing line structure design mainly relies on the float to control the position and stability, it cannot be fixed on the ice surface and is prone to slippage, which leads to increased positioning deviation and reduced sampling accuracy. Therefore, the existing technology has significant shortcomings when facing special environments such as frozen water bodies and is difficult to meet the needs of field water quality sampling in all climates and all weather conditions.
[0005] Therefore, those skilled in the art provide a fishing rod-type electric water sampler to solve the problems mentioned in the background art. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] Please see Figures 1-3As shown, this utility model provides a technical solution: a fishing rod-type electric water sampler, including an electric telescopic rod 1, which allows for height adjustment, facilitating flexible operation in environments with varying ice thicknesses, water surfaces, or shorelines, while also improving operator safety. The electric telescopic rod 1 is equipped with a delivery pipe 2, one end of which is fitted with an electric water pump 3, and the other end with an ice-breaking mechanism 5. The ice-breaking mechanism 5 includes:
[0027] The outer shell 51 has several spiked protrusions 53 arranged in an array at its bottom. The spiked protrusions 53 are fixed to the ice surface to prevent slippage, making the subsequent rotating icebreaker cone head 58 work more stably and efficiently. The inner wall of the outer shell 51 is equipped with a telescopic motor 54. The output shaft of the telescopic motor 54 is fixedly connected to a drive motor 55. The output shaft of the drive motor 55 is equipped with a protective component 6. The protective component 6 is connected to a hollow connector 56. The protective component 6 is used to transmit power. The outer wall of the hollow connector 56 is equipped with an internal heating element 57. The bottom of the hollow connector 56 is equipped with a cone head 58.
[0028] Telescopic tube 59, one end of which is fixedly connected to the inner wall of hollow connector 56, and the other end of which is fixedly connected to conveying pipe 2. In use, the electric telescopic rod 1 is extended, and the spiked protrusion 53 of the ice-breaking mechanism 5 is placed on the ice surface. The spiked protrusion 53 increases the friction. Then, the telescopic motor 54 is turned on to drive the drive motor 55 downward. The drive motor 55 drives the hollow connector 56, the inner heating element 57, and the conical head 58 to rotate through the protective component 6, so that the conical head 58 can spirally cut into the ice layer. The inner walls of the hollow connector 56, the inner heating element 57, and the conical head 58 are hollow. The electric water pump 3 is turned on to pump water into the conveying pipe 2 through the hollow connector 56, the inner heating element 57, and the conical head 58.
[0029] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, a suspension line 4 is provided on the outer casing 51. One end of the suspension line 4 is fixedly connected to the outer casing 51, and the other end of the suspension line 4 is fixedly connected to the electric telescopic rod 1.
[0030] As one implementation method in this embodiment, please refer to Figures 1-3 As shown, an external heating element 52 is provided on the spike protrusion 53. The external heating element 52 is used to heat the spike protrusion 53. When the ice surface is extremely smooth, ordinary spikes are easy to slip. However, after being heated, the spike protrusion 53 will partially melt the ice surface to form a micro-melting zone. After cooling, it forms a "thermal anchoring" effect, that is, the spike and the ice surface are partially fused and frozen, which improves the adhesion and stability and prevents shaking or displacement during operation.
[0031] As one implementation method in this embodiment, please refer to Figures 1-6As shown, the protective component 6 includes a connecting sleeve 61, which is fixedly connected to the top of the hollow connector 56. The inner wall of the connecting sleeve 61 is rotatably connected to the output shaft of the drive motor 55. A spring 62 is provided on the output shaft of the drive motor 55. One end of the spring 62 is fixedly connected to the inner wall of the output shaft of the drive motor 55, and the other end of the spring 62 is fixedly connected to a conical block 63. The conical block 63 is slidably connected to the inner wall of the output shaft of the drive motor 55. A conical groove 64 is provided on the inner wall of the connecting sleeve 61. When the output shaft of the drive motor 55 rotates, the output shaft of the drive motor 55 drives the conical block 63 to rotate. Under the action of the spring 62, the conical block 63 abuts against the conical groove 64, so that the conical block 63... The conical grooves 64 generate circumferential forces, causing the connecting sleeve 61 to rotate. The connecting sleeve 61 drives the hollow connecting piece 56 to rotate, which in turn drives the conical head 58 to rotate. When the resistance to rotation is too great, the spring 62 is compressed due to excessive pressure, causing the conical block 63 to retract into the inner wall of the output shaft of the drive motor 55, cutting off the driving force. When the conical head 58 encounters significant resistance during ice breaking or rotation, such as excessive ice thickness or obstruction by foreign objects, the conical block 63 retracts into the inner wall of the output shaft of the drive motor 55 after the spring 62 is compressed, actively disengaging from the conical grooves 64. This cuts off the power transmission path between the output shaft of the drive motor 55 and the connecting sleeve 61, preventing the drive motor 55 from stalling and burning out.
[0032] As one implementation method in this embodiment, please refer to Figures 1-6 As shown, the outer surface of the conical head 58 is provided with a spiral cutting edge to enhance the cutting efficiency during ice breaking and reduce ice resistance. A one-way check valve is provided between the electric water pump 3 and the delivery pipe 2 to prevent backflow of the extracted water sample.
[0033] As one implementation method in this embodiment, please refer to Figures 1-6 As shown, the conveying pipe 2 is made of flexible and cold-resistant material, which can remain soft and non-brittle in low-temperature environments. The electric telescopic rod 1 is equipped with a positioning buckle structure, which is used to achieve stable locking at different length positions.
[0034] As one implementation method in this embodiment, please refer to Figures 1-6 As shown, the internal heating element 57 is a resistance heating wire, which is wound around the outer wall of the hollow connector 56 and covered with an insulating coating. The electric water pump 3 is a low-noise DC micro pump to reduce the disturbance to aquatic organisms in the water.
[0035] As one implementation method in this embodiment, please refer to Figures 1-6 As shown, the handheld end of the electric telescopic pole 1 is equipped with a non-slip grip and a cold-proof covering layer to improve operating comfort and winter performance. The external heating element 52 and the internal heating element 57 share the same power control system and have an automatic power-off protection function for overheating.
[0036] Working principle: The fishing rod-type electric water sampler is carried to the ice surface to be sampled. When in use, the electric telescopic rod 1 is extended, and the spiked protrusion 53 of the ice-breaking mechanism 5 is placed on the ice surface. The spiked protrusion 53 increases the friction. Then, the telescopic motor 54 is turned on to drive the drive motor 55 downward. The drive motor 55 drives the hollow connector 56, the internal heating element 57, and the conical head 58 to rotate through the protective component 6, so that the conical head 58 can spirally cut into the ice layer. The inner walls of the hollow connector 56, the internal heating element 57, and the conical head 58 are hollow. The electric water pump 3 is turned on to pass water into the delivery pipe 2 through the hollow connector 56, the internal heating element 57, and the conical head 58 for sampling.
[0037] When the output shaft of the drive motor 55 rotates, it drives the conical block 63 to rotate. Under the action of the spring 62, the conical block 63 abuts against the conical groove 64, causing the conical block 63 and the conical groove 64 to generate a circumferential force, which causes the connecting sleeve 61 to rotate. The connecting sleeve 61 drives the hollow connecting piece 56 to rotate, and the hollow connecting piece 56 drives the conical head 58 to rotate. When the rotational resistance is too great, the spring 62 is compressed due to excessive pressure, causing the conical block 63 to retract into the inner wall of the output shaft of the drive motor 55, cutting off the driving force. When the conical head 58 encounters significant resistance during ice breaking or rotation, such as excessive ice thickness or obstruction by foreign objects, the conical block 63 retracts into the inner wall of the output shaft of the drive motor 55 after the spring 62 is compressed, actively disengaging from the conical groove 64, thereby cutting off the power transmission path between the output shaft of the drive motor 55 and the connecting sleeve 61, preventing the drive motor 55 from stalling and burning out.
