Description

Technical Field

[0001] The utility model relates to the technical field of seawater pump controllers, in particular to a frequency conversion control device for a seawater pump controllable by a ship. Background Art

[0002] Seawater pumps are suitable for fire fighting, equipment cooling, and seawater desalination on offshore platforms. They can also be used for heating ground source heat pump air conditioners in coastal areas, all seawater lifting purposes, coastal square fountain landscapes, seawater aquaculture, etc. The equipment has low noise, high efficiency, and energy saving. It is suitable for various seawater, alkaline corrosive water, impurity-free clean water, chilled water / cooling water, rainwater, underground water from coal mines, iron mines, metal mines, drinking water, mineral water, etc. The controller refers to the main command device that controls the start, speed regulation, braking, and reverse of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit in a predetermined order. It consists of a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller. It is the "decision-making body" that issues commands, that is, it completes the coordination and command of the entire computer system. The existing seawater pump controller lacks a shock-absorbing mechanism, and the ship is prone to shaking during navigation. In the long run, the seawater pump controller is easily damaged, which affects the service life. At the same time, the seawater pump controller will also generate high temperature when working. In order not to affect its working performance, a large number of heat dissipation holes are generally opened. The externally installed controller is prone to dust accumulation, which affects the use of the controller. Therefore, a frequency conversion control device for seawater pumps that can be controlled by ships is proposed. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The frequency converter is supported by a combination of a damping spring, a connecting spring, a connecting rod and a movable block. When the ship is bumpy, the frequency converter compresses the damping spring, causing the internal spring of the damping spring to deform elastically, absorb part of the energy, and generate a reaction force. At the same time, the internal damper consumes energy through friction and fluid resistance, reducing the energy of the vibration system. Combined with elastic deformation and energy dissipation, the damping spring can effectively reduce the vibration amplitude of the structure, reduce the impact of the impact on the frequency converter, protect the frequency converter from damage, extend the service life of the frequency converter and improve safety, play a shock-absorbing and buffering role for the frequency converter, effectively reduce the impact force, and effectively avoid damage to the frequency converter.

[0013] 2. The temperature inside the frequency converter is detected by the temperature sensor, and the temperature signal is transmitted to the frequency converter through the temperature sensor. When the set value is reached, the frequency converter controls the drive motor and the electric telescopic operation, so as to timely dissipate heat inside the frequency converter, with a high degree of automation and timely cooling and heat dissipation. When the drive motor is running, the power output end of the drive motor rotates to drive the transmission rod, the transmission rod rotates to drive the second bevel gear, the second bevel gear rotates to drive the shaft, the shaft rotates to drive the fixing part, the fixing part rotates to drive the heat dissipation blades, the heat dissipation blades rotate to form air convection, accelerate the air flow inside and outside the frequency converter housing, replace the hot air, and accelerate the heat dissipation effect. When the electric telescopic rod is controlled to run, the movable end of the electric telescopic rod moves to drive the baffle to move, and the movement of the baffle drives the second heat dissipation hole thereon to move, so that the second heat dissipation hole is connected with the first heat dissipation hole, thereby opening the first heat dissipation hole, which is convenient for the internal and external replacement of hot air. When not in use, the first heat dissipation hole can also be closed to prevent external dust, debris, and insects from entering the frequency converter, thereby ensuring the safety of the frequency converter.
