Description

Technical Field

[0001] The utility model relates to the technical field of electric circuit devices, in particular to a ship electric circuit control device. Background Art

[0002] The converter in the electric propulsion system is an electric energy conversion component that plays a connecting role. The converter receives the constant voltage and frequency AC power from the diesel engine, converts the constant voltage and frequency AC power into variable voltage and frequency AC power for the propulsion motor, and the propulsion motor drives the propeller through the gearbox to achieve the ship's forward, backward, traction, braking, acceleration, deceleration, parking and other actions. Therefore, it is necessary to set up a special ship electrical circuit control device to provide comprehensive control and protection for the electrical circuits of the diesel engine, converter, gearbox, propulsion motor, ship status, ship clock, etc.

[0003] For example, a ship electrical circuit control device with patent announcement number CN214478477U can install an air handling cabinet under the control cabinet to suck in the humid air in the ship through an exhaust fan, heat the internal temperature of the air handling cabinet through a heating plate to dry the humid air, and then perform secondary treatment through a lime storage box to ensure the efficiency of air entering the control cabinet, ensure that the air entering the control cabinet is dry air and then extracted, thereby ensuring air circulation in the control cabinet and preventing humid air from entering and causing harm to the electrical circuits.

[0004] Although the above equipment can dry the humid air in the control cabinet by installing an air handling cabinet, a heating plate and a lime storage box, and perform secondary treatment to ensure the efficiency of air entering the control cabinet, the control cabinet and the cabinet door are mostly simple opening and closing cooperation, the cooperation gap is large and the locking device is not reliable. For ships operating at sea, moisture will cause additional closed loops between circuits, increasing the abnormal loss of electric energy. At the same time, the box is fixed by flanges and multiple sets of screws, making it very inconvenient to disassemble the box to repair the internal electrical components. For this reason, we propose a new type of ship electrical circuit control device. Utility Model Content

[0028] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a ship electrical line control device, comprising:

[0029] A control cabinet 4, wherein a vent 3 is provided at the top of the control cabinet 4, and a cabinet door 1 is installed at one end of the control cabinet 4;

[0030] A replacement mechanism 5, arranged inside the control cabinet 4, for replacing electrical components;

[0031] The locking mechanism 2 is arranged outside the control cabinet 4 and is used to fix the control cabinet door 1 on the control cabinet 4 .

[0032] The replacement mechanism 5 comprises:

[0033] A horizontal plate 505 is installed at both ends of the inner side of the control cabinet 4, and thread grooves are set at both ends of the horizontal plate 505. A screw 502 is installed on the inner side of the thread groove, a rotating block 504 is installed on the top of the screw 502, and a fixing nut 506 is installed on the outer wall of the screw 502. The fixing nut 506 is located at the top of the horizontal plate 505. A sliding plate 501 is installed at the bottom end of the screw 502, and a storage plate 503 is installed on the inner side of the sliding plate 501.

[0034] like Figure 2 As shown, it should be noted that: by setting the sliding plate 501, it is convenient to disassemble and replace the electrical components on the storage plate 503, the top of the sliding plate 501 is fixedly connected with the screw 502, and rotating the rotating block 504 can adjust the distance between the sliding plate 501 and the horizontal plate 505, so as to adapt to different electrical components. After adjusting to the appropriate position, the screw 502 can be fixed to the horizontal plate 505 by screwing the fixing nut 506 alone, thereby fixing the sliding plate 501.

[0035] The locking mechanism 2 comprises:

[0036] A keyhole plate 210 is installed on one side of the cabinet door 1, and an installation box 209 is installed on the same side of the control cabinet body 4. An auxiliary box 212 is installed at the bottom of the installation box 209. A sliding box 202 is installed on one side of the auxiliary box 212. A movable groove 201 is provided on the other side of the auxiliary box 212, and a sliding rod 203 is installed on the inner side of the sliding box 202.

[0037] A second spring 217 is installed on the inner side of the auxiliary box 212, a fixed column 216 is installed on the top of the second spring 217, a trapezoidal block 219 is installed on one side of the top of the fixed column 216, a movable rod 213 is installed on the outer wall of the fixed column 216, the movable rod 213 is located in the movable groove 201, a trapezoidal groove 218 is provided on the inner side of the fixed column 216, and one end of the sliding rod 203 is located in the trapezoidal groove 218.

[0038] A plug pin 211 is installed at one end of the inner side of the installation box 209, and the plug pin 211 is located on the inner side of the keyhole plate 210. A blocking ring 215 is installed at one end of the plug pin 211, and the blocking ring 215 is attached to one side of the trapezoidal block 219. A push rod 206 is installed at the other end of the blocking ring 215, and a fixing sleeve 214 is installed on the outer wall of the push rod 206.

[0039] First springs 208 are installed at both ends of the fixing sleeve 214, a fixing ring 207 is installed at one end of the first spring 208, a crank 204 is installed on the outer wall of the fixing ring 207, a sliding rod 203 is installed on the inner side of the other end of the crank 204, and a pushing plate 205 is installed at one end of the pushing rod 206.

[0040] like Figure 3 As shown, it should be noted that: pushing the fixed ring 207 can compress the first spring 208, and at the same time the crank 204 will drive the sliding rod 203 to slide. During the sliding process of the sliding rod 203, the fixed column 216 can be lowered through the trapezoidal groove 218. At this time, the movable rod 213 is located at the bottom of the movable groove 201. After the fixed column 216 is lowered, the trapezoidal block 219 will not block the blocking ring 215. After there is no obstruction, the stored force generated by the compression of the first spring 208 will be released, and the pin 211 will be ejected synchronously as if it were a lock. In the orifice plate 210, the second spring 217 drives the fixed column 216 to rise, and the movable rod 213 is located at the top of the movable groove 201, fixing and limiting the cabinet door 1 and the control cabinet body 4. When the cabinet door 1 needs to be opened, the movable rod 213 is pushed down to the bottom of the movable groove 201, and the push plate 205 is pulled through the push rod 206 to drive the blocking ring 215 to pass over the trapezoidal block 219. After passing over the trapezoidal block 219, the movable rod 213 is released, and the second spring 217 rebounds again to cause the trapezoidal block 219 to limit the blocking ring 215.

[0041] In summary, the ship electrical circuit control device, by pushing the fixing ring 207 to synchronously drive the sliding rod 203 and the pushing rod 206 to move, can drive the fixing column 216 to descend, so that the plug 211 is ejected into the keyhole plate 210, and the cabinet door 1 and the control cabinet body 4 can be fixed, thereby improving the airtightness of the device; at the same time, by setting the sliding plate 501, it is convenient to disassemble, replace and repair the electrical components on the storage plate 503, and the position of the storage plate 503 can be adjusted by rotating the screw 502 to meet the installation of electrical components of different specifications, thereby improving the compatibility and practicality of the device.
