Embodiment 1

[0021] according to Figure 1 to Figure 5 As shown, the present embodiment is a kind of equipment for controlling cyanobacteria, including a hull 4, a mixing device 5 fixedly installed above the front of the hull, two input pipes 2 connected to both sides of the mixing device in rotation, fixedly connected to two The sludge collection device 1 at the other end of the input pipe is connected to the mixing device at one end, and the output pipe 6 near the propeller at the tail of the hull is arranged at the other end, and the lifting device 3 fixedly installed above the rear of the hull to adjust the height of the sludge collection device .

[0022] Described silt collecting device comprises the base plate 11 of a rectangular frame shape, the baffle cover 12 that is fixedly connected on the base plate, the silt stirring blade 14 that is connected between the two ends of the baffle cover by bearing, and is fixedly connected in the baffle cover. One end of the cover and the first...

Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 lies in the difference of the elevating device. The elevating device of this embodiment includes a bracket 33, and the bracket at least includes two parallel side plates and a joint welded between the ends of the two side plates. A top plate, a reel 32 is installed between the two side plates of the support, and a second motor 31 for driving the reel forward and reverse is installed on a side plate; a rope 321 is wound on the reel, and a rope 321 is wound in the middle of the rope. It is fixed with the reel, and the two ends of the reel are respectively connected with two tension sensors, the other end of the tension sensor is fixedly connected with the middle part of the input pipe, and the tension sensor and the second motor are respectively electrically connected with the controller. In this way, the magnitude of the pulling force measured by the pulling force sensor can determine whether the silt collection devi...

Abstract

The invention discloses a device for preventing and controlling blue-green algae. The device comprises a mixing device installed in the front of a ship body, two input pipes rotationally connected to the two sides of the mixing device, a sludge collecting device connected to the other ends of the two input pipes, an output pipe with one end connected with the mixing device and the other end arranged near a propeller at the tail portion of the ship body, and a lifting device installed above the rear portion of the ship body and used for adjusting the height of the sludge collecting device. River bottom sludge and river water are mixed through sludge stirring blades of the sludge collecting device, sludge containing water is sucked into the mixing device through the input pipes by means of a water suction pump, the sludge containing water is stirred through the mixing device, evenly mixed with liquid chemicals added in a liquid chemical barrel and then discharged through a water outlet pipe, the sludge is evenly scattered on the water surface through the effect of the propeller of the ship body, the sludge adsorbs nutrient enrichment components in water in the sedimentation process and brings the nutrient enrichment components to the river bottom, the nutrient enrichment degree of river water is changed, the survival conditions of blue-green algae are broken, and the effect of preventing and controlling the excessive growth of blue-green algae is achieved.

Description

technical field [0001] The invention belongs to the field of water treatment equipment, and in particular relates to an equipment structure for preventing and controlling blue algae. Background technique [0002] At present, most of the means to prevent the excessive growth of blue-green algae are to directly salvage the blue-green algae, which cannot change the problem of eutrophication of the water body. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device with a novel and reasonable structure and a good effect of preventing and controlling blue algae pollution in view of the deficiencies in the prior art. [0004] In order to realize the purpose of the present invention, adopt the following technical proposals to realize: a kind of equipment of preventing and treating blue-green algae, comprises hull, is fixedly installed on the mixing device above the front part of the hull, rotates and connects two input...
