It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0035] Embodiment 1:

[0036] The present invention provides an automatic pipe reel device, comprising a pipe reel rack 1, a power mechanism and a detection mechanism, wherein the pipe reel rack 1 is mounted on a rotating shaft 5, and a storage space is provided on the pipe reel rack 1 along the circumference, and the storage space is used to store a pressure pipe 8, the power mechanism and the detection mechanism are both mounted on the pipe reel rack 1, and the power mechanism can output driving power to drive the pipe reel rack 1 to rotate around the axis of the rotating shaft 5 at a preset speed, thereby realizing the retraction and release of the pressure pipe 8, and the pressure pipe 8 generates winding pressure on the pipe reel rack 1, and the detection mechanism is used to detect the winding pressure, wherein the driving power matches the winding pressure, and the detection mechanism preferably adopts a pressure sensor 4. The power mechanism adopts a DC motor or an AC motor.

[0037] In the present invention, the pressure in the pressure tube 8 is detected by the pressure sensor 4. When the pressure in the high-pressure tube 8 increases, the high-pressure tube 8 is tightened and presses the pressure sensor 4. The greater the pressure inside the pressure tube 8, the greater the pressure the pressure sensor 4 can withstand.

[0038] Specifically, the present invention also includes a control mechanism, the control architecture includes a main control board 3 and a potentiometer, the main control board 3 is electrically connected to the power mechanism and the potentiometer respectively, the power mechanism includes a motor 7 and a reducer 6, and the main control board 3 is electrically connected to the motor 7.

[0039] Specifically, a storage space is provided inside the pipe reel rack 1, and the control mechanism and the power mechanism are both installed inside the storage space, which can fully utilize the internal space of the pipe reel rack 1 and is conducive to the miniaturization of the equipment.

[0040] Specifically, the power mechanism and the pipe reel 1 adopt any one of gear transmission, belt transmission and chain transmission.

[0041] The pipe reel rack 1 includes a pipe reel hub 2, and side plates 9 are respectively provided on both sides of the pipe reel hub 2 in the radial outward direction. The pipe reel hub 2 is fixedly connected or rotationally matched with the rotating shaft 5 in the radial inward direction. The power mechanism drives the pipe reel rack 1 to rotate by driving the rotating shaft 5 or directly drives the pipe reel rack 1 to rotate.

[0042] Embodiment 2:

[0043] This embodiment is a preferred example of Embodiment 1.

[0044] In this embodiment, Figure 1 , Figure 2 As shown, the pipe reel 1 is integrally connected with the rotating shaft 5, and the rotating shaft 5 is installed on the load-bearing frame. The power mechanism includes a motor 7 and a reducer 6. The reducer 6 and the rotating shaft 5 are transmitted by gears. When the motor 7 drives the reducer 6 to rotate, the reducer 6 can drive the rotating shaft 5 to rotate through the gears and then drive the pipe reel 1 to rotate to realize the retraction and extension of the pressure pipe 8.

[0045] Embodiment 3:

[0046] This embodiment is another preferred example of Embodiment 1.

[0047] In this embodiment, the tube reel rack 1 includes a tube reel hub 2. Side plates 9 are respectively provided on both sides of the tube reel hub 2 in the radially outward direction. The tube reel hub 2 rotates in cooperation with the rotating shaft in the radially inward direction.

[0048] Furthermore, the pipe reel rack 1 is rotatably matched with the rotating shaft 5 through the pipe reel hub 2 through bearings. Both ends of the rotating shaft 5 are fixed on the load-bearing frame. Two support plates are provided on the load-bearing frame. The two support plates are respectively arranged at both ends of the accommodating space. The motor 7 and the reducer 6 are both installed on the support plates and extend into the accommodating space. The reducer 6 and the inner wall of the pipe reel rack 1 are transmitted by gears. When the motor 7 drives the reducer 6 to rotate, the reducer 6 can drive the pipe reel rack 1 to rotate around the rotating shaft 5 through gears, thereby realizing the retraction and extension of the pressure pipe 8.

[0049] Taking Example 2 as an example, the working principle of the present invention is as follows:

[0050] The pressure sensor 4 is installed on the pipe reel hub 2 at the center of the pipe reel rack 1 and can detect the winding pressure of the pressure pipe 8 on the pipe reel hub 2. The potentiometer is installed on the main control board 3. The potentiometer converts the external pressure signal into an electrical signal and transmits it to the main control board 3. The main control board 3, the motor 7, and the reducer 6 are all installed in the accommodating space inside the pipe reel hub 2. The main control board 3 is electrically connected to the motor 7. After receiving the electrical signal from the potentiometer, the main control board 3 converts the signal into a current signal, adjusts the current of the motor 7, and thus adjusts the input power of the motor 7, so that the motor 7 can keep the pipe reel rack 1 rotating at a constant speed under different loads.

[0051] Furthermore, the motor 7, the reducer 6, and the rotating shaft 5 are connected in sequence, the motor 7 provides a rotational power source for the rotating shaft 5, the reducer 6 converts the high rotation speed of the motor 7 into a set rotational speed for uniform rotation, the rotating shaft 5 is fixedly connected to the pipe reel rack 1, and the motor 7 provides a rotational power source for the pipe reel rack 1.

[0052] When the pressure sensor 4 is under pressure, it transmits a signal to the potentiometer at the back, and the potentiometer adjusts the resistance value of the potentiometer according to the pressure signal transmitted by the pressure sensor 4. The signal is transmitted to the main control board 3 through the change of resistance value. The greater the pressure on the pressure sensor 4, the greater the change in the resistance value of the adjustment potentiometer, and the greater the current after the signal conversion of the main control board 3. The main control board 3 adjusts the power of the motor (7) according to the real-time resistance value and thus adjusts the output power. The motor (7) is connected to the reducer 6 to achieve the set speed rotation.

[0053] After receiving the signal from the potentiometer, the main control board 3 will adjust the input power of the motor 7 accordingly to maintain the dynamic balance of the rotation of the pipe reel 1. When the pressure of the pressure pipe 8 is low, the load on the pipe reel 1 is small, and the load of the motor 7 is reduced accordingly. Under the condition of unchanged speed, the demand for the output power of the motor 7 is reduced. At the same time, the smaller the pressure on the pressure sensor 4, the smaller the current converted by the main control board 3. At this time, the motor 7 reduces the input power, and the output power of the motor 7 will be reduced accordingly. When the pressure of the high-pressure pipe 8 increases, the load on the pipe reel 1 increases, and the load of the motor 7 increases accordingly. Under the condition of unchanged speed, the demand for the output power of the motor increases. At the same time, the greater the pressure on the pressure sensor 4, the greater the current converted by the main control board 3, and the corresponding input and output power of the motor 7 will increase accordingly. In this way, through the adjustment of the main control board 3, when the pressure of the high-pressure pipe 8 changes, the speed of the motor 7 will remain unchanged, so that the uniform rotation of the pipe reel 1 can be guaranteed.
