Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment 1

[0025] like Figure 1 As shown, a water quality detection device for a reservoir environment includes a sampling mechanism and a detection platform.

The detection platform is equipped with a GPS locator 2, a wind turbine 1, and a photovoltaic panel 3. The sampling mechanism includes a sampler 7. The sampler 7 enters and exits the detection platform through the sampling channel 8. The sampling channel 8 is an inverted cone. The power cabin 5 is provided with a power cabin water inlet 55 on the side close to the sampling channel 8. The power cabin water inlet 55 is located on the conical surface of the sampling channel 8; the detection cabin 4 surrounds the sampling channel 8, and the sampler 7 and the detection cabin 4 are connected by a hose.

[0026] Through the above arrangement, the sampling channel 8 is used to store the sampler 7 when it stops working, which is beneficial to transport the water quality detection device to avoid damage to the sampler 7, and to avoid damage to the sampler 7 when the water quality detection device is moved in the reservoir environment; the power cabin water inlet 55 of the power cabin 5 is arranged on one side of the sampling channel 8, and the sampling channel 8 will block the animals in the reservoir environment to prevent animals from entering the power cabin 5; the water inlet of the inverted cone-shaped sampling channel 8 is small, which is beneficial to avoid debris and aquatic plants and animals from entering the sampling channel 8; the water on the cone surface generates downward pressure, and the water flow rate entering the power cabin 5 through the power cabin water inlet 55 is faster; the sampler 7 needs to sample water at different depths in the reservoir environment. In order to facilitate the lowering and recovery of the sampler 7 and the transportation of the water sample in the sampler 7 to the detection cabin 4, the sampler 7 and the detection cabin 4 are connected by a bendable and hollow hose.

[0027] Combination Figure 2 and Figure 3As shown, the detection chamber 4 includes a partition plate 44 and six detection devices. The partition plate 44 separates and fixes the detection devices. The partition plate 44 is provided with through holes, which allow the detection devices to communicate with each other. The detection devices include a pH sensor 41, a conductivity sensor 42, a dissolved oxygen sensor 43, a data processor and a communication module, and their battery packs.

[0028] Through the above-mentioned settings, the detection equipment is separated by a partition board 44, and the detection cabin 4 is divided into fixed areas. Different detection equipment is arranged in each area to facilitate maintenance; the partition board 44 assists in fixing the detection equipment to prevent the detection equipment from colliding with each other or the inner wall of the detection cabin 4 during the movement of the water quality detection equipment; further, the surface of the partition board 4 is provided with an elastic material layer, such as a replaceable partition board filled with sponge, which can effectively protect the detection equipment and absorb the water vapor in the detection cabin 4 at the same time.

[0029] Combination Figure 4 , Figure 5 and Figure 6 As shown, the detection platform also includes a power cabin 5, which includes four power devices, which are evenly distributed around the bottom of the power cabin 5. The power cabin water inlet 55 corresponds to the power device, which includes a water pump 51 and a water quality improvement mechanism. The water quality improvement mechanism includes a filter basket 53 and a baffle 54. The filter basket 53 is located below the power cabin water inlet 55. A counterweight is provided in the empty position of the power cabin 5 to lower the overall center of gravity of the water quality detection device and prevent the water quality detection device from overturning due to impact or other reasons. The power device can enable the water quality detection device to move in the reservoir environment, so that the reservoir detection device can detect the water quality of the reservoir at different locations, collect the overall water quality data of the reservoir, and better reflect the water quality status of the reservoir; the power device is provided with a filter basket 53, which can filter the water entering and leaving the power device, remove aquatic plants or debris in the water body, and prevent the power device from being blocked; the filter basket 53 can collect the filtered aquatic plants or debris, which has the effect of improving the water quality of the water body; the filter basket 53 prevents aquatic plants or debris from entering the water pump 51, and prevents the water pump 51 from being blocked or damaged.

[0030] like Figure 1 , Figure 2 Figure 3 As shown, Figure 2The direction of the middle arrow is the direction of water flow. Four fenders 6 are arranged outside the detection cabin 4, and the positions of the fenders 6 correspond to the power device; counterweights are arranged inside the detection cabin 4 and the power cabin 5. At least two fenders 6 are arranged outside the detection platform, and the fenders 6 include an absorption part 61, and the absorption part 61 is provided with at least two mutually parallel absorption grooves 64 away from the detection platform, and the bottom of the absorption groove 64 is provided with a fender drainage hole 65. The water quality detection device moves in the reservoir environment to prevent aquatic animals and debris from actively or passively colliding with the detection cabin 4. A fender 6 is arranged outside the detection cabin 4 to avoid damage to the detection device in the detection cabin 4; during the recovery process of the water quality detection device, the water quality detection device needs to be docked or close to the ship. In order to avoid a rigid collision between the water quality detection device and the shore or the side of the ship, a fender 6 is arranged outside the detection cabin 4 to reduce the impact force; the absorption part 61 of the fender 6 is provided with an absorption groove 64, which can release the impact force of the wave perpendicular to the detection platform along the direction of the absorption groove 64, and at the same time can effectively slow down the ups and downs of the detection platform caused by the waves; the fender drain hole 65 can discharge the water flow that flows into the fender 6 due to the approach of floating objects and aquatic animals to the detection platform, forming a water flow away from the detection platform, which has a driving effect on the approaching floating objects and aquatic animals; the fender drain hole 65 is provided at the bottom of the absorption groove 64, which can prevent the fender drain hole 65 from being deformed when the absorption part 61 is hit.

The connecting part is fixed outside the detection platform, and the absorbing part 61 is slidably connected to the connecting part 62. The upper and lower surfaces of the connecting part 62 are provided with fender water inlets 63. When the impactor approaches, water flows into the inside of the fender 6 through the fender water inlet 63. Since the absorbing part 61 and the connecting part 62 are slidably connected, when the water flows out from the fender drain hole 65, it forms a water flow away from the detection platform, reducing the relative speed between the detection platform and the impactor, and at the same time, pushing the absorbing part 61 to extend out of the connecting part 62 to meet the possible impact. When the impactor collides with the absorbing part 61, since the absorbing part 61 and the connecting part 62 are slidably connected, the water flow that continuously flows into the connecting part from the fender water inlet 63 needs to be compressed during the retraction of the absorbing part 61, which can further absorb the impact force generated by the impact.

[0032] The water quality detection device moves in the reservoir environment to prevent aquatic animals and debris from actively or passively colliding with the detection cabin 4. A fender 6 is arranged outside the detection cabin 4 to avoid damage to the detection device in the detection cabin 4. During the recovery process of the water quality detection device, the water quality detection device needs to be docked or close to the ship.
