Description

A mechanical controllable water surface walking mechanism

technical field

The invention relates to a water surface walking mechanism, in particular to a mechanically controllable water surface walking mechanism, which belongs to the technical field of water surface walking mechanisms.

Background technique

Studies have found that, except for 20%-30% of the nutrients such as nitrogen and phosphorus input into the water body are absorbed and utilized by aquatic organisms, the rest all enter the water body environment, and about 60-70% of them are deposited in the mud bottom. On the one hand, the existence of a large amount of organic matter in the bottom mud not only leads to bottom sedimentation, but also produces reducing substances such as ammonia nitrogen, nitrite, methane, hydrogen sulfide, etc., causing deterioration of water quality and seriously affecting the safety of the water environment. On the other hand, the mud bottom of the water body is also a nutrient pool, and a large amount of nutrients needed for the primary productivity of the water body come from the mud bottom. Reasonable release and utilization of nutrients in the bottom mud is an important way to improve the bottom environment and water body productivity.

At present, domestic and foreign treatment methods for water body sediment mainly include mechanical dredging, microbial improvement, and chemical drug adjustment. Mechanical dredging mainly uses water conservancy pond dredging units to remove the silt at the bottom of the water. This method cannot reuse the nutrients in the bottom mud; although the microbial method improves the resource utilization of nutrients in the bottom mud, it cannot be controlled. The growth conditions of microorganisms cannot stabilize the effect; although chemical methods are effective, they are easy to cause the accumulation of chemical residues, which are harmful to farmed animals and pollute the water environment, which cannot fundamentally solve the problem.

In order to realize the conditioning and improvement of the bottom mud of the water body, people will use a solar bottom sediment control machine to improve the bottom mud of the water body. This solar energy substrate control machine is usually provided with a water surface self-propelled mechanism. The publication date is January 8, 2014, and the Chinese patent document with document number CN102942296B discloses a "water surface controllable walking mechanism". When the travel control block is in contact with the travel switch, the travel switch is triggered to send a signal, and the motor is controlled to reverse through the controller module, so as to achieve the purpose of linear motion of the traction rope in the opposite direction. It can be seen that the control method of the water surface controllable walking mechanism needs to be equipped with multiple electronic control components, and the motor must also use a forward and reverse bidirectional motor, so the reliability is low and failures are prone to occur; and once a failure occurs, the on-site management Personnel cannot inspect and maintain it, and it needs to be removed from the floating body on the river surface, loaded by ship, transported ashore, and then sent to a specific place for fault inspection, which makes inspection and maintenance very inconvenient.

A spring 2-6 is sheathed on the push rod 2-5 of the guide rod assembly 2 for the smooth pushing of the push rod 2-5.

The magnet assembly 1-6 is disc-shaped.

The box assembly 1 has an elliptical or approximately elliptical structure.

The inner wall of the box assembly 1 is also provided with a pair of gear limit blocks, gear limit blocks A1-12 and gear limit blocks B1-15, and the gear limit blocks 1-15 are limited.
