Description

Technical Field

[0001] This utility model relates to the field of tugboat technology, specifically a protection structure for the steering gear of a port tugboat. Background Technology

[0002] A tugboat steering gear is an electric actuator capable of precisely controlling the rotation of a tugboat's steering surface. It receives command signals from an autopilot or manual control panel, and through internal components such as a motor, gear set, encoder, and control circuit, converts the signals into torque and speed, thereby driving the steering surface to continuously change angle and direction and maintain control.

[0003] When operating in the specific low-temperature environment of a port, the grease used in tugboat steering gear undergoes significant changes in its physical properties. Specifically, as the temperature decreases, the viscosity of the grease increases significantly. Viscosity is a measure of the fluidity of grease; high viscosity means the grease is more viscous and its fluidity is reduced. This change adversely affects the operating efficiency and performance of the tugboat steering gear.

[0004] First, the increased viscosity of the lubricating grease directly leads to an increase in mechanical damping. Mechanical damping refers to the energy dissipation caused by internal friction, material damping effects, and other factors during the vibration or motion of a mechanical system. In a servo system, high-viscosity lubricating grease increases the frictional resistance between moving parts, requiring the servo to overcome greater resistance when rotating, thereby reducing the system's response speed and flexibility.

[0005] Secondly, increased mechanical damping further affects the dynamic characteristics of the servo motor. Dynamic characteristics typically include key performance indicators such as system response time, stability, and accuracy. Under low-temperature conditions, the additional resistance caused by the high viscosity of the lubricating grease significantly prolongs the servo motor's response time; that is, the time from issuing a rudder command to the rudder blade actually reaching the designated position increases. This is highly disadvantageous for tugboats that require rapid and accurate adjustments to their course. Simultaneously, increased mechanical damping can also lead to instability in servo motor control, making the servo motor more prone to oscillations or overshoot during operation, reducing steering precision and reliability. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a protection structure for the steering gear of a port tugboat, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protection structure for a port tugboat steering gear, comprising a steering gear body, a temperature sensor, and a temperature control component;

[0008] The temperature sensor is mounted on the servo motor body, and the sensing end of the temperature sensor extends through and into the interior of the servo motor body. The temperature control component is mounted on the outside of the servo motor body.

[0009] The temperature control component includes a housing disposed on the outside of the servo motor body, a liquid storage tank disposed on the upper side of the servo motor body, the liquid storage tank being connected to the housing via a drain pipe, and at least one electric heating element being installed inside the liquid storage tank.

[0010] A water pump with its input end connected to the storage tank is installed on the outside of the storage tank, and a connecting pipe with one end connected to the tank body is connected to the output end of the water pump.

[0011] Furthermore, a water injection pipe is provided on the top of the liquid storage tank.

[0012] Furthermore, an aqueous solution is added inside the storage tank, and the heating element is located in the aqueous solution for heating the aqueous solution.

[0013] Furthermore, the temperature sensor is wired to the water pump and the heating element.

[0014] Furthermore, the side of the housing closest to the servo motor body is missing.

[0015] Furthermore, the housing is welded to the outside of the servo motor body.

[0016] Furthermore, the end of the drain pipe away from the tank body is connected to the bottom of the storage tank.

[0017] Furthermore, the liquid storage tank is connected to the tank body by at least two support members, and the side cross-section of the support member is a right-angled triangle.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. The port tugboat steering gear protection structure, through the installation of temperature control components, including electric heating elements, water pumps, liquid storage tanks and housings, can heat the lubricating grease inside the steering gear body in cold weather, effectively preventing the lubricating grease from becoming too viscous, thereby ensuring the normal operation and performance of the steering gear.

[0020] 2. The port tugboat steering gear protection structure uses an electric heating element to heat the aqueous solution inside the storage tank. The heated aqueous solution is then pumped into the tank, filling it with hot water. Once the tank is full, the hot water is drained back into the storage tank, forming a circulating heating system that maintains a constant water temperature inside the tank, thus continuously and effectively heating the lubricating grease inside the steering gear.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 In this embodiment, a port tugboat steering gear protection structure is used to heat the grease inside the steering gear body 1 in cold weather to prevent the grease inside the steering gear body 1 from becoming too viscous.

[0027] Specifically, it includes a servo motor body 1, a temperature sensor 2, and a temperature control component 3; the temperature sensor 2 is installed on the servo motor body 1, and the sensing end of the temperature sensor 2 penetrates and extends into the interior of the servo motor body 1, while the temperature control component 3 is installed on the outside of the servo motor body 1.

[0028] In actual setup, temperature sensor 2 is installed on servo body 1, and the sensing end of temperature sensor 2 is ensured to penetrate and extend into the interior of servo body 1 to accurately measure the temperature of internal grease. Temperature sensor 2 continuously monitors the temperature of grease inside servo body 1. When the temperature drops to a level that may affect the performance of grease, temperature control component 3 will automatically start and transmit mass to temperature control component 3. Temperature control component 3 heats the interior of servo body 1 to prevent excessive grease viscosity.

[0029] Please see Figure 2-3In order to heat the lubricating grease inside the servo motor body 1, the temperature control component 3 in this embodiment includes a housing 301 located on the outside of the servo motor body 1, a liquid storage tank 302 located on the upper side of the servo motor body 1, the liquid storage tank 302 being connected to the housing 301 via a drain pipe 303, and at least one electric heating element 304 installed inside the liquid storage tank 302; a water pump 305 located on the outside of the liquid storage tank 302 with its input end connected to the liquid storage tank 302, and a connecting pipe 306 connected at one end to the housing 301 being connected to the output end of the water pump 305.

[0030] It should be noted that a water injection pipe 307 is provided on the top of the liquid storage tank 302. Aqueous solution can be added into the liquid storage tank 302 through the water injection pipe 307, so that the heating element 304 is located in the aqueous solution and the aqueous solution inside the liquid storage tank 302 is heated by the heating element 304.

[0031] In actual use, the aqueous solution heated by the heating element 304 is pumped by the water pump 305 into the interior of the housing 301, filling the interior of the housing 301 with hot water. The hot water then transfers its heat to the servo motor body 1. During this process, once the housing 301 is full of hot water, it is pumped back to the storage tank 302 through the drain pipe 303, and so on, keeping the water temperature inside the housing 301 constant. This effectively heats the grease inside the servo motor body 1, thereby reducing the viscosity of the grease.

[0032] In actual setup, the end of the drain pipe 303 furthest from the tank 301 is connected to the bottom of the storage tank 302.

[0033] Furthermore, in order to facilitate monitoring of the temperature of the lubricating grease inside the servo motor body 1, and to control the operation of the water pump 305 and the heating element 304, the temperature sensor 2 in this embodiment is wired to the water pump 305 and the heating element 304.

[0034] It should be noted that the above-mentioned electronic devices and their electrical connection methods are all existing technologies. However, the main innovation of this application lies in the design of its mechanical structure. This application mainly protects how to cleverly set up the temperature sensor 2, water pump 305, electric heating element 304 and their mechanical connection and layout with the servo motor body 1 to ensure that the lubricating grease inside the servo motor body 1 can be effectively heated in cold weather, while maintaining the stability and reliability of the system.

[0035] In addition, in order to ensure that the hot water in the housing 301 can effectively transfer its internal heat to the servo motor body 1, the side of the housing 301 near the servo motor body 1 in this embodiment is missing, and the housing 301 is welded to the outside of the servo motor body 1.

[0036] In actual setup, the hot water injected into the detailed 301 comes into direct contact with the outer surface of the servo body 1, thereby effectively transferring the heat from the hot water to the lubricating grease inside the servo body 1.

[0037] Furthermore, in order to improve the stability of the liquid storage tank 302 installation, in this embodiment the liquid storage tank 302 is connected to the box body 301 by at least two support members, and the shape of the side cross section of the support member is a right triangle.

[0038] In addition, when encountering high temperatures and the internal temperature of the servo motor body 1 is too high and heat dissipation is required, coolant can be added to the inside of the liquid storage tank 302, and the heating element 304 can be turned off. The coolant can be pumped and circulated by the water pump 305, so that the coolant flows on the outside of the servo motor body 1, thereby effectively dissipating heat from the servo motor body 1.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
