[0017] 1. This energy-saving control device for a 10KV industrial frequency refrigeration unit is provided with a control panel, a switch, a finger pad, an electromagnet, a winding drum, a card plate, a card slot and a permanent magnet. The staff holds two handles with both hands respectively and presses the switch synchronously. The electromagnet disconnects the power supply and the control panel can be removed from the side of the control cabinet body. The finger pad provides support for the holding fingers, and the two switches are connected in series to the power supply to ensure that the electromagnet is demagnetized under the premise that the staff holds the control panel stably, thereby ensuring safe control. After removing the control panel, the staff can move freely with the control panel and adjust the unit components after moving to a position where the unit components can be visually seen, thereby ensuring convenient control. The first control cable is wound on the winding drum. When the control panel is moved, the winding drum The baffle plate rotates relative to the mounting plate, and the first control cable wrapped around the surface of the drum is released to adapt to the movement of the control panel. The card plate can be taken out from the inside of the card slot, and the mounting plate and the baffle plate are placed on the ground. When the control panel is moved, the mounting plate and the baffle plate are pulled by the first control cable to roll and move with the control panel, so that the staff can reel in the first control cable anytime and anywhere. After the control panel moves to the position where long-term positioning is required, the staff will control the switch with both hands synchronously again, and the electromagnet will conduct electricity again, so that the control panel can be adsorbed on the iron structure at the positioning position to ensure flexible installation. When the electromagnet fails, the changing mechanism and the electromagnet can be disassembled, and the control panel can be adsorbed and fixed by permanent magnets, thereby improving the device's ability to cope with failures.

[0018] 2. This energy-saving control device for a 10KV industrial frequency refrigeration unit is equipped with a crank, a shaft seat, a rotating head, a key slot and a limit key. By turning the crank, the baffle and the winding drum can be driven to rotate, and the first control cable can be actively retracted and released. The crank is held and rotated with the rotating shaft as the axis. The rotation is stopped after the limit key is aligned with the key slot. The rotating head is pushed along the slide groove until the limit key is inserted into the key slot to complete the connection between the rotating head and the shaft seat. The crank is stabilized in the horizontal direction to facilitate the rotation of the baffle and the winding drum. When the crank is not in use, the above operation is reversed, the key slot is pulled out from one side of the limit key, and the rotating head is pulled along the slide groove. At this time, the crank is parallel to the baffle, which is convenient for the storage of the crank.

[0019] 3. The energy-saving control device of a 10KV industrial frequency refrigeration unit is provided with a fixed clamp, a movable clamp, a spring, a rotating handle and a supporting block. When the first control cable needs to be fixed, the end of the first control cable close to the control panel is inserted between the fixed clamp and the movable clamp. The movable clamp is displaced after being pushed upward by the first control cable, and the spring is squeezed together with the pressure plate. The movable clamp presses and fixes the first control cable through the reaction force of the spring. The limit rod limits the movement direction of the movable clamp. When the first control cable needs to be released, the supporting block is rotated by the rotating handle so that the longer side of the supporting block is supported between the two clamping grooves. The supporting block bears the pressure of the spring instead of the first control cable, and the movable clamp leaves the outer wall of the first control cable. At this time, the first control cable can freely pass through the gap between the fixed clamp and the movable clamp.

[0020] 4. This energy-saving control device for a 10KV industrial frequency refrigeration unit, by setting a steering rod, a steering ball, a screw rod, a stud and a screw sleeve, the steering rod and the steering ball can both be rotated, and the installation angle and installation position of the control panel can be adjusted by rotating the steering ball and the steering rod, which is convenient for the staff to use. After the angle and position adjustment are completed, the screw rod is rotated by the knob to make the two steering rods move towards each other, increasing the pressure on the steering balls, so that the two steering balls will not be deflected by their own weight, thereby completing the positioning of the angle and position of the control panel. The guide rod limits the direction of the steering rods when they move towards each other to avoid the steering ball from detaching. The steering ball is rotated, and the stud rotates synchronously and separates from the screw sleeve, which is convenient for the disassembly of the steering mechanism.

When it is necessary to fix the first control cable 15, the end of the first control cable 15 close to the control panel 4 is inserted between the fixed clamp 32 and the movable clamp 33. The movable clamp 33 is displaced after being pushed upward by the first control cable 15, and the spring 41 is squeezed together with the pressure plate 20.

The length of the support block 44 is greater than its own height, and a turning handle 45 is fixedly connected to the middle of one side of the support block 44.

The steering ball 26 and the steering rod 6 can be rotated to adjust the installation angle and installation position of the control panel 4, which is convenient for the staff to use. After the angle and position adjustment are completed, the screw rod 24 is rotated by the knob 7 to make the two steering rods 6 move in a direction close to each other, increase the pressure on the steering ball 26, so that the two steering balls 26 will not be deflected by the influence of their own weight, thereby completing the positioning of the angle and position of the control panel 4. The guide rod 25 limits the direction of the steering rods 6 when they move towards each other to prevent the steering balls 26 from detaching.

The electromagnet 5 disconnects the power supply and the control panel 4 can be removed from the side of the control cabinet body 1. The finger pad 30 provides support for the holding fingers, and the two switches 31 are connected in series to the power supply to ensure that the electromagnet 5 is demagnetized under the premise that the staff holds the control panel 4 stably, thereby ensuring safe operation. After removing the control panel 4, the staff can carry the control panel 4 and move freely. After moving to a point where the unit components can be visually seen, the unit components can be adjusted to ensure convenient operation. The first control cable 15 is wound around the winding The reel 12 and the baffle 13 rotate relative to the mounting plate 11 when the control panel 4 is moved. The first control cable 15 on the surface of the reel 12 is released to adapt to the movement of the control panel 4. The card plate 22 can be taken out from the inside of the card slot 23, and the mounting plate 11 and the baffle 13 are placed on the ground. When the control panel 4 is moved, the mounting plate 11 and the baffle 13 are pulled by the first control cable 15 to roll and move with the control panel 4, so that the staff can reel in the first control cable 15 anytime and anywhere. After the control panel 4 moves to the position where long-term positioning is required, the staff again controls the switch 31 with both hands synchronously, and the electromagnet 5 conducts electricity again, so that the control panel 4 can be adsorbed on the iron structure at the positioning position to ensure flexible installation. When the electromagnet 5 fails, the direction-changing mechanism and the electromagnet 5 can be disassembled, and the control panel 4 can be adsorbed and fixed by the permanent magnet 18.
