Description

Technical Field

[0001] This utility model relates to the field of power controller technology, and more specifically, to a dual-power ventilation shaft butterfly valve control device. Background Technology

[0002] Because the ventilation shaft butterfly valve control system is controlled by a single power source, when power outages or ventilation stoppages occur in places such as coal mines, the ventilation system will be affected, leading to poor air circulation in the mine and potentially causing safety hazards such as gas accumulation and insufficient oxygen. In order to reduce the operator's operation time during the reversing operation, a dual-power ventilation shaft butterfly valve control device is set up to switch between the main power source and the backup power source, ensuring that the control device has a stable power supply at all times and ensuring that the reversing operation is completed within the specified time.

[0003] A search revealed Chinese patent application number 202321142819.2, which discloses a dual-power supply switching control device, relating to the field of power control technology. The device includes a main body with a control component on its front side. The control component includes a fixing plate fixedly mounted on the front side of the main body. A fixing pin is threaded onto the front side of the fixing plate. A controller is fixedly mounted on the front side of the fixing plate, with a display screen embedded in its front side and control keys fixedly mounted thereon. Mounting bolts are threaded onto the front side of the mounting plate. This invention's monitoring module can monitor the dual-power supply status. When the power supply is abnormal or fails, the monitoring module can switch the power supply, thus enabling the device to maintain a normal power supply state. This ensures normal power supply during power outages or abnormalities, improving the reliability of the device's power supply. The control module can control the drive module to operate according to the backup power supply voltage status, improving the convenience of control and adjustment.

[0004] The above patent still has the following shortcomings: (1) The cable connection is prone to loosening. Due to the harsh underground environment, the connection between the device and the cable is prone to loosening due to vibration, movement or external force during the use of the device, resulting in poor circuit contact. This will not only affect the normal operation of the equipment, but may also cause short circuits, leading to electrical failures, fires and other safety accidents.

[0005] (2) It is inconvenient to connect cables. In the process of using existing devices, bolts are usually used to hold the cable in place and connect the cable to the internal circuit of the device. The connection process requires the use of tools, which reduces the installation efficiency of the device.

[0006] Therefore, a dual-power supply control device for the butterfly valve of the ventilation shaft is urgently needed to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to address the existing defect of easy loosening of cable connections. Due to the harsh underground environment, the connection between the device and the cable is prone to loosening during use due to vibration, movement or external force, resulting in poor circuit contact.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A dual-power ventilation shaft butterfly valve control device includes a mounting bracket, and further includes,

[0010] A power controller is installed on one side of the mounting bracket, and an indicator light is installed at the top of one side of the power controller. A manual switching knob is installed inside the bottom of one side of the power controller.

[0011] A backup power connector is installed on one side of the power controller and is electrically connected to the power controller. A wiring structure is provided at the top of the backup power connector.

[0012] A common power connector is installed on the other side of the power controller, and the common power connector is electrically connected to the power controller. The top of the common power connector has a common power connection port, and the bottom of the common power connector has a load power connection port. Both the common power connector and the backup power connector have conductive copper plates installed inside.

[0013] The wiring structure is installed inside the main power supply terminal, the load power supply terminal, and the backup power supply terminal, respectively, for connecting and fixing the cable to the device;

[0014] A reinforcement structure is respectively installed at the top of the backup power connector and at both ends of the main power connector. The reinforcement structure includes a rotating seat rotatably connected to the top of the backup power connector and at both ends of the main power connector, a pressure plate fixed to one side of the rotating seat, a second fixing seat fixed to one side of the pressure plate, and a locking assembly installed on one side of the pressure plate.

[0015] As a preferred technical solution of this application, the locking assembly includes a fixing plate fixed to the top of the backup power connector and the two ends of the main power connector respectively, a first fixing seat installed on one side of the fixing plate and a lead screw rotatably connected to the top of the fixing plate, a baffle fixed to the top of the pressure plate and located outside the lead screw, and a screw cap threaded to the outside of the lead screw.

[0016] As a preferred technical solution of this application, the lead screw is provided in two sets, and the two sets of lead screws are symmetrically distributed on the vertical center line of the pressure plate.

[0017] As a preferred technical solution of this application, the second fixed seat and the first fixed seat are located on the same horizontal center line, and the pressure plate and the rotating seat are welded together as an integrated structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the scheme of this application:

[0022] 1. By pulling the pressure plate, the second and first fixed seats come into contact with the cable. Rotating the nut pushes the pressure plate toward the fixed plate, so that the second and first fixed seats fix the position between the cable and the device. This realizes the connection reinforcement function of the device, effectively reducing the risk of wire breakage caused by cable loosening, bending or external force, ensuring a stable connection between the device and the air shaft butterfly valve, and making the cable arrangement more neat and orderly, which is convenient for subsequent wiring, maintenance and management.

[0023] 2.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1-4 As shown, the dual-power ventilation shaft butterfly valve control device proposed in this embodiment includes a mounting bracket 1, and further includes...

[0031] Power controller 2 is installed on one side of mounting bracket 1, and an indicator light 3 is installed on the top of one side of power controller 2. A manual switching knob 8 is installed inside the bottom of one side of power controller 2.

[0032] A backup power connector 11 is installed on one side of the power controller 2 and is electrically connected to the power controller 2. A wiring structure 9 is provided at the top of the backup power connector 11.

[0033] The common power connector 6 is installed on the other side of the power controller 2, and the common power connector 6 and the power controller 2 are electrically connected. The top of the common power connector 6 is provided with a common power connection port 5, and the bottom of the common power connector 6 is provided with a load power connection port 7. Both the common power connector 6 and the spare power connector 11 are equipped with conductive copper sheets 12.

[0034] Wiring structure 9 is installed inside the common power supply terminal 5, the load power supply terminal 7 and the backup power supply terminal 10 respectively, and is used to connect and fix the cable to the device.

[0035] The reinforcement structure 4 is respectively disposed at the top of the backup power connector 11 and at both ends of the main power connector 6. The reinforcement structure 4 includes a rotating seat 406 rotatably connected to the top of the backup power connector 11 and the two ends of the main power connector 6, a pressure plate 407 fixed to one side of the rotating seat 406, a second fixing seat 408 fixed to one side of the pressure plate 407, and a locking assembly disposed on one side of the pressure plate 407.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the locking assembly further includes a fixing plate 401 fixed to the top of the backup power connector 11 and both ends of the main power connector 6, a first fixing seat 402 mounted on one side of the fixing plate 401 and rotatably connected to the top of the fixing plate 401, a baffle 404 fixed to the top of the pressure plate 407 and located outside the lead screw 403, and a screw cap 405 threadedly connected to the outside of the lead screw 403. Two sets of lead screws 403 are provided, and the two sets of lead screws 403 are symmetrically distributed on the vertical center line of the pressure plate 407. The second fixing seat 408 and the first fixing seat 402 are located on the same horizontal center line. The pressure plate 407 and the rotating seat 406 are welded together. Pulling the pressure plate 407 causes the rotating seat 406 to rotate the pressure plate 407. Then, the second fixed seat 408 and the first fixed seat 402 are located on the outside of the cable. Rotating the lead screw 403 causes the lead screw 403 to be inserted into the baffle 404. At the same time, the nut 405 is located on one side of the baffle 404. Rotating the nut 405 causes the nut 405 to move towards the fixed plate 401 through the thread on the surface of the lead screw 403. At the same time, the nut 405 pushes the pressure plate 407 towards the fixed plate 401, so that the second fixed seat 408 and the first fixed seat 402 clamp the outer surface of the cable, fixing the position between the cable and the device.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, the wiring structure 9 further includes a connecting piece 904 installed inside the common power connector 6 and connected to the conductive copper sheet 12, a groove 905 formed on one side of the connecting piece 904, a rotating shaft 903 fixed inside the common power connector 6, a cam 902 rotatably connected to the outside of the rotating shaft 903, and a hand lever 901 fixed to the top of one side of the cam 902. The side cross-section of the connecting piece 904 has a "U" shaped structure. When the hand lever 901 moves into the interior of the common power connector 6, the convex... The wheel 902 squeezes the connecting piece 904. By pulling the lever 901 to one side, the cam 902 rotates around the shaft 903 and separates from the connecting piece 904. At the same time, the connecting piece 904 is released from the squeezing of the cam 902 and unfolds, allowing the cable to be fully inserted into the interior of the connecting piece 904. Then, the lever 901 is pushed to drive the cam 902 to rotate, causing the cam 902 to squeeze the connecting piece 904. The connecting piece 904 then clamps and fixes the cable, making full contact between the cable and the connecting piece 904, and conducting the current through the connecting piece 904 to the interior of the conductive copper sheet 12.

[0038] Specifically, when using this dual-power ventilation well butterfly valve control device: the main power cable is connected to the main power connector 6 through the main power connection port 5, the backup power cable is connected to the backup power connector 11 through the backup power connection port 10, and the ventilation well butterfly valve load cable is connected to the main power connector 6 through the load power connection port 7, thus connecting the power controller 2 to the power supply and detecting the power current. Under normal use, the main power current is introduced into the load power connection port 7 through the power controller 2 to supply the ventilation well butterfly valve. When the power controller 2 detects that the main power current is disconnected, the power controller 2 disconnects from the main power cable and then introduces the backup power cable into the load power connection port 7, connecting the backup power cable to the ventilation well butterfly valve load cable. The cable is fixed by the wiring structure 9, and the cable is reinforced by the reinforcement structure 4 to prevent the cable from loosening or falling off.

[0039] By pulling the lever 901 to one side, the cam 902 rotates around the shaft 903 and separates from the connecting piece 904. At the same time, the connecting piece 904 is released from the pressure of the cam 902 and unfolds, allowing the cable to be fully inserted into the interior of the connecting piece 904. Then, the lever 901 is pushed to rotate the cam 902, causing the cam 902 to press against the connecting piece 904. The connecting piece 904 then clamps and fixes the cable, ensuring full contact between the cable and the connecting piece 904, and conducting the current through the connecting piece 904 to the interior of the conductive copper sheet 12.

[0040] After the cable wiring is completed, pull the pressure plate 407 to make the rotating seat 406 drive the pressure plate 407 to flip. Then, the second fixed seat 408 and the first fixed seat 402 are located on the outside of the cable. Rotate the lead screw 403 to insert the lead screw 403 into the baffle 404. At the same time, the nut 405 is located on one side of the baffle 404. Rotate the nut 405 to move it through the thread on the surface of the lead screw 403 toward the fixed plate 401. At the same time, the nut 405 pushes the pressure plate 407 toward the fixed plate 401, so that the second fixed seat 408 and the first fixed seat 402 clamp the outer surface of the cable and fix the position between the cable and the device. At the same time, the pressure plate 407 can limit the hand lever 901 to prevent the cam 902 from loosening and rotating.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
