[0007] Preferably, a wire-passing hole is opened at the top of the mounting plate, and one end of the first control cable close to the first wiring seat is inserted into the inside of the wire-passing hole.

[0008] Preferably, a shaft seat is fixedly connected to the top of the side of the baffle away from the control cabinet body. A rotating head is rotatably connected to the side of the shaft seat away from the baffle. A crank is fixedly connected to the end of the rotating head away from the shaft seat.

[0009] Preferably, a limiting key is fixedly connected to the inner wall of the shaft seat, and a key groove adapted to the limiting key is opened at one end of the rotating head close to the shaft seat.

[0010] Preferably, sliding grooves are opened on both sides of the shaft seat. The same rotating shaft is inserted into the two sliding grooves. The rotating shaft is rotatably connected to the middle of the rotating head. Snap rings are fixedly connected to both ends of the rotating shaft. The shaft seat is located between the two snap rings. The outer diameter of the snap ring is larger than the height of the inner wall of the sliding groove.

[0011] Preferably, a fixed clamp is fixedly connected to one side of the baffle close to the mounting plate. Limit rods are fixedly connected to the four corners of the side of the fixed clamp close to the mounting plate. The same pressing plate is fixedly connected to the ends of the four limit rods away from the fixed clamp. A moving clamp is slidably connected to the middle parts of the four limit rods.

[0015] Preferably, a wire-binding hoop is fixedly connected to the outer wall of one of the steering rods. The middle of the second control cable is clamped inside the wire-binding hoop.

[0016] Compared with the prior art, the present invention provides an energy-saving control device for a 10KV power-frequency refrigeration unit, which has the following beneficial effects:

[0017] 1. The energy-saving control device for a 10KV power frequency refrigeration unit. By setting a control panel, switches, finger pads, electromagnets, winding drums, clamping plates, card slots, and permanent magnets, when the staff holds two handles with both hands and presses the switches simultaneously, the power supply of the electromagnets is cut off, and the control panel can be removed from the side of the control cabinet body. The finger pads provide support for the held fingers, and the two switches are connected in series to the power supply to ensure that the electromagnets are demagnetized on the premise that the staff firmly holds the control panel, guaranteeing operation safety. After removing the control panel, the staff can move freely with the control panel. After walking to a position where the unit components can be visually observed, the unit components can be regulated, ensuring convenient operation. The first control cable is wound on the winding drum. When moving the control panel, the winding drum and the baffle rotate relative to the mounting plate, and the first control cable on the surface of the winding drum is released to adapt to the movement of the control panel. The clamping plate can be taken out from the inside of the card slot, and the mounting plate and the baffle are placed on the ground. When moving the control panel, the mounting plate and the baffle roll under the traction of the first control cable and move along with the control panel, facilitating the staff to wind up the first control cable at any time and anywhere. After the control panel moves to a position where long-term positioning is required, the staff controls the switches synchronously with both hands again, and the electromagnets conduct electricity again, and the control panel can be adsorbed to the iron structure at the positioning place, ensuring flexible installation. When the electromagnets fail, the steering mechanism and the electromagnets can be disassembled, and the control panel is adsorbed and fixed by the permanent magnets, improving the device's ability to handle failures.

[0018] 2. The energy-saving control device for a 10KV power frequency refrigeration unit. By setting a crank, a shaft seat, a rotating head, a keyway, and a limit key, turning the crank drives the baffle and the winding drum to rotate, and the first control cable can be actively wound and unwound. Hold the crank and rotate around the rotating shaft. Stop rotating after the limit key aligns with the keyway. Push the rotating head along the chute until the limit key is inserted into the keyway, completing the connection between the rotating head and the shaft seat, stabilizing the crank in the horizontal direction, facilitating driving the baffle and the winding drum to rotate. When the crank is not in use, reverse the above operation, pull out the keyway from one side of the limit key, and pull the rotating head along the chute. At this time, the crank is parallel to the baffle, facilitating the storage of the crank.

[0019] 3. The energy-saving control device of the 10KV power frequency refrigeration unit fixes the first control cable by setting a fixed clamp, a movable clamp, a spring, a turning handle and a support 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. After the movable clamp is pushed upward by the first control cable and generates displacement, it squeezes the spring together with the pressure plate. The movable clamp compresses and fixes the first control cable through the reaction force of the spring. The limiting rod limits the moving direction of the movable clamp. When the first control cable needs to be released, the support block is rotated by turning the turning handle so that the longer side of the support block supports between the two clamping grooves. The support 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. The energy-saving control device of the 10KV power frequency refrigeration unit adjusts the installation angle and position of the control panel by setting a steering rod, a steering ball, a screw rod, a stud and a nut sleeve. Both the steering rod and the steering ball can rotate. Rotating the steering ball and the steering rod can adjust the installation angle and position of the control panel, which is convenient for the staff to use. After the angle and position adjustment are completed, the screw rod is rotated by turning the knob, so that the two steering rods move towards each other, increasing the pressure on the steering ball, so that the two steering balls will not deflect under the influence of their own weight, thus completing the positioning of the angle and position of the control panel. The guide rod limits the direction when the steering rods move towards each other to prevent the steering ball from detaching. Rotating the steering ball, the stud rotates synchronously and separates from the nut sleeve, which is convenient for the disassembly of the steering mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

On the side of the mounting plate 11 away from the control cabinet body 1, a winding drum 12 is rotatably connected. On the side of the winding drum 12 away from the control cabinet body 1, a baffle 13 is fixedly connected. On the outer wall of the control cabinet body 1 close to the winding drum 12, a first wiring seat 10 is arranged. In the middle of the side of the control cabinet body 1 close to the winding drum 12, a positioning plate 3 is embedded. On the side of the positioning plate 3 away from the control cabinet body 1, an electromagnet 5 is magnetically adsorbed. On the side of the electromagnet 5 away from the control cabinet body 1, a direction-changing mechanism is rotatably connected. At one end of the direction-changing mechanism away from the control cabinet body 1, a control panel 4 is rotatably connected. On the side of the control panel 4 close to the control cabinet body 1, a permanent magnet 18 is fixedly connected. Between the control panel 4 and the first wiring seat 10, the same first control cable 15 is fixedly connected. The middle part of the first control cable 15 is wound around the outer wall of the winding drum 12. On both sides of the control panel 4, side frames 8 are fixedly connected. On the sides of the two side frames 8 away from the control cabinet body 1, handles 9 are fixedly connected. On the inner walls of the two handles 9, finger pads 30 are fixedly connected. On the tops of the two finger pads 30 on the side close to the control cabinet body 1, switches 31 are fixedly connected. Between the electromagnet 5 and the control panel 4, a second control cable 17 is fixedly connected. The electromagnet 5 is connected to a power supply through the second control cable 17. Both switches 31 are connected in series in the circuit where the electromagnet 5 and the power supply are located.

[0031] In the present invention, a wire passing hole 21 is opened at the top of the mounting plate 11. One end of the first control cable 15 close to the first wiring seat 10 is inserted into the inside of the wire passing hole 21.

[0032] In the present invention, on the top of the side of the baffle 13 away from the control cabinet body 1, a shaft seat 34 is fixedly connected. On the side of the shaft seat 34 away from the baffle 13, a rotating head 37 is rotatably connected. At one end of the rotating head 37 away from the shaft seat 34, a rocking handle 14 is fixedly connected. By rotating the rocking handle 14, the baffle 13 and the winding drum 12 are driven to rotate, and the first control cable 15 can be actively retracted and released.

[0033] In the present invention, a limiting key 35 is fixedly connected to the inner wall of the shaft seat 34. A key groove 38 adapted to the limiting key 35 is opened at one end of the rotating head 37 close to the shaft seat 34.

[0034] In the present invention, chutes 36 are provided on both sides of the shaft seat 34. A same rotating shaft 39 is inserted into the two chutes 36. The rotating shaft 39 is rotatably connected to the middle of the rotating head 37. Snap rings 40 are fixedly connected to both ends of the rotating shaft 39. The shaft seat 34 is located between the two snap rings 40. The outer diameter of the snap ring 40 is greater than the height of the inner wall of the chute 36. Hold the crank 14 and rotate it with the rotating shaft 39 as the axis. Stop rotating after aligning the limit key 35 with the key slot 38. Push the rotating head 37 along the chute 36 until the limit key 35 is inserted into the key slot 38, completing the connection between the rotating head 37 and the shaft seat 34, stabilizing the crank 14 in the horizontal direction, facilitating driving the baffle 13 and the winding drum 12 to rotate. When the crank 14 is not in use, reverse the above operation, pull out the key slot 38 from one side of the limit key 35, and pull the rotating head 37 along the chute 36. At this time, the crank 14 is parallel to the baffle 13, facilitating the storage of the crank 14.

[0035] In the present invention, a fixed clamp 32 is fixedly connected to the side of the baffle 13 close to the mounting plate 11. Limit rods 42 are fixedly connected to the four corners of the side of the fixed clamp 32 close to the mounting plate 11. A same pressing plate 20 is fixedly connected to the ends of the four limit rods 42 away from the fixed clamp 32. A same movable clamp 33 is slidably connected to the middle of the four limit rods 42. A same spring 41 is fixedly connected between the movable clamp 33 and the pressing plate 20. When it is necessary to fix the first control cable 15, insert the end of the first control cable 15 close to the control panel 4 between the fixed clamp 32 and the movable clamp 33. After the movable clamp 33 is subjected to the upward thrust of the first control cable 15, it generates displacement, and together with the pressing plate 20, compresses the spring 41. The movable clamp 33 presses and fixes the first control cable 15 through the reaction force of the spring 41. The limit rods 42 limit the movement direction of the movable clamp 33.

[0036] In the present invention, clamping grooves 43 are provided on the sides of the movable clamp 33 and the fixed clamp 32 close to each other. A same support block 44 is clamped between the two clamping grooves 43. The length of the support block 44 is greater than its own height. A rotating handle 45 is fixedly connected to the middle of one side of the support block 44. When it is necessary to release the first control cable 15, rotate the support block 44 through the rotating handle 45 so that the longer side of the support block 44 supports between the two clamping grooves 43. The support block 44 bears the pressure of the spring 41 instead of the first control cable 15. The movable clamp 33 leaves the outer wall of the first control cable 15. At this time, the first control cable 15 can freely pass through the gap between the fixed clamp 32 and the movable clamp 33.

[0037] In the present invention, the direction-changing mechanism includes a screw rod 24, two steering rods 6, two steering balls 26 and two guide rods 25. The screw rod 24 is rotatably connected to the middle of one of the steering rods 6, the screw rod 24 is threadedly connected to the other steering rod 6, one end of the screw rod 24 is fixedly connected to a knob 7, the two guide rods 25 are fixedly connected to the side of one of the steering rods 6, and the two guide rods 25 are slidably connected to the other steering rod 6. Both the steering rod 6 and the steering ball 26 can rotate. Rotating the steering ball 26 and the steering rod 6 can 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 towards each other, increasing the pressure on the steering balls 26, so that the two steering balls 26 will not deflect under the influence of their own weight, thereby completing the positioning of the angle and position of the control panel 4. The guide rods 25 define the direction when the steering rods 6 move towards each other to prevent the steering balls 26 from detaching.

[0038] In the present invention, on the side of the electromagnet 5 close to the control panel 4, there are fixedly connected with screw sleeves 28. On the side of the two screw sleeves 28 close to each other, there are threadedly connected with screw studs 27. The two steering balls 26 are respectively fixedly connected to the two screw studs 27. Rotating the steering balls 26, the screw studs 27 rotate synchronously and separate from the screw sleeves 28, which is convenient for the disassembly of the direction-changing mechanism.

[0039] In the present invention, a cable binding hoop 16 is fixedly connected to the outer wall of one of the steering rods 6. The middle of the second control cable 17 is clamped inside the cable binding hoop 16. The position of the second control cable 17 is restricted by the cable binding hoop 16 to prevent the second control cable 17 from interfering with the steering rod 6 during the process of adjusting the control panel 4.

[0040] In use, the control circuit of the 10KV industrial frequency refrigeration unit is centrally installed inside the control cabinet body 1. The control panel 4 is connected to the control circuit inside the control cabinet body 1 through the first control cable 15. The unit can be stably adjusted from the outside through the control panel 4 and is not affected by wireless signals. The staff holds the two handles 9 with both hands and presses the switches 31 simultaneously. The electromagnet 5 is powered off, and the control panel 4 can be removed from the side of the control cabinet body 1. The finger pads 30 provide support for the held fingers, and the two switches 31 are connected in series to the power supply to ensure that the electromagnet 5 is demagnetized on the premise that the staff stably holds the control panel 4, ensuring operation safety. After removing the control panel 4, the staff can move the control panel 4 freely. After walking to a position where the unit components can be visually observed, the unit components can be controlled, ensuring convenient operation. The first control cable 15 is wound on the winding drum 12. When the control panel 4 is moved, the winding drum 12 and the baffle 13 rotate relative to the mounting plate 11, and the first control cable 15 on the surface of the winding drum 12 is released to adapt to the movement of the control panel 4. The clamping plate 22 can be taken out from the inside of the clamping groove 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 roll under the traction of the first control cable 15 and move along with the control panel 4, facilitating the staff to wind up the first control cable 15 at any time and anywhere. After the control panel 4 is moved to a position where long-term positioning is required, the staff controls the switches 31 synchronously with both hands again, and the electromagnet 5 conducts electricity again, and the control panel 4 can be adsorbed on the iron structure at the positioning place, ensuring flexible installation. When the electromagnet 5 fails, the steering mechanism and the electromagnet 5 can be disassembled, and the control panel 4 is adsorbed and fixed by the permanent magnet 18.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
