Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be accurately conveyed to those skilled in the art.

[0025] Embodiment one

[0026] As Figures 1-6 shown, the utility model discloses a kind of fire hose storage measuring device, which is installed with support shaft 12 on the front side of support plate 2, rotatingly installed with guide wheel 4 outside support shaft 12, rotatingly installed with rotary encoder 11 at the front end of guide wheel 4, and the rotary encoder can detect the rotating number of guide wheel;First connecting rod 9 and second connecting rod 8 are also fixedly installed on support shaft 12 simultaneously. Wherein, the other end of first connecting rod 9 is inclined to left and down, and first rotating shaft 1 is rotatingly installed at the front side of its terminal end, and the rear end of first rotating shaft is coaxially connected with first drive motor 10, and the first drive motor 10 is fixed on support plate 2;The other end of second connecting rod 8 is inclined to right and down, and second rotating shaft 6 is rotatingly installed at the front side of its terminal end, and the rear end of second rotating shaft is coaxially connected with second drive motor 10, and the second drive motor 10 is slidingly connected with support plate 2 in vertical plane.The end of fire hose is fixed on first rotating shaft 1, and first motor 10 drives first rotating shaft 1 to rotate, so that fire hose can be wound on the outside of first rotating shaft 1 in a circle, to realize the rapid storage of fire hose. After the end of fire hose 3 located at the outermost side of first rotating shaft 1 is fixed on second rotating shaft 6 across guide wheel 4, second drive motor 14 is started to rotate, and second drive motor 14 drives second rotating shaft 6 to rotate, so that fire hose 3 is reversed from first rotating shaft 1 to second rotating shaft 6 in a circle, and fire hose is always transmitted to second rotating shaft 6 through guide wheel 4, so as to drive guide wheel 4 to rotate, and rotary encoder 11 coaxially arranged with guide wheel 4 counts the rotation of guide wheel, and finally the length of fire hose is obtained according to the following formula.

[0027]

[0028] In the formula, L: total length of fire hose;

[0029] L1: length of first connecting rod;

[0030] L2: second link length;

[0031] D: guide wheel diameter;

[0032] Φ: angle of hose on the guide wheel;

[0033] N: total number of rotations of the rotary encoder.

[0034] Example Two

[0035] To ensure that the fire hose 3 and the guide wheel 4 are in full contact and can drive the guide wheel 4 to rotate, a tightening adjustment mechanism 5 is provided on the upper part of the second link 8, which can adjust the included angle between the two links according to specific needs to achieve the optimal angle of wrap.

[0036] The tightening adjustment mechanism 5 is selected from a pneumatic cylinder or an electric cylinder, the upper end of which is fixedly connected with the support plate 2, and the lower end of which is designed as a spherical surface tangent to the upper side of the link. When the pneumatic cylinder or electric cylinder is extended, the second link 8 is pressed down, the angle formed by the two links becomes smaller, and correspondingly, the angle of wrap of the fire hose on the outside of the guide wheel becomes larger. Since the movement of the second link 8 is a rotation with the support shaft 12 as the center, the point where the pneumatic cylinder or electric cylinder is released from the second link 8 is not fixed, and the end of the pneumatic cylinder or electric cylinder is designed as a spherical surface, the contact mode is changed to tangency, which can adjust the contact point in time according to the position of the second link 8, without interference. To prevent the pneumatic cylinder or electric cylinder from pressing the second link 8 down indefinitely, a buffer mechanism is also provided on the support plate 2. The buffer mechanism includes a spring 7, and an arc-shaped recess is formed on the support plate, the arc shape of the arc-shaped recess is parallel to the movement track of the second link 8, and the spring 7 is slidingly installed in the recess. The second drive motor 14 is slidingly installed at the upper end of the spring in the recess, and is subjected to the upward tightening force of the spring 7, and the position of the second link 8 is fixed between the tightening force of the pneumatic cylinder or electric cylinder and the reverse force of the spring.

[0037] Example Three

[0038] The inductor 13 is installed at the front side of the support plate 2 and outside each rotating shaft, and a load sensor is arranged on the rotating shaft. When the load exceeds a certain load, the power is cut off, the motor stops, and the water hose conveying is completed. The distance from the inductor 13 to the center of the rotating shaft is greater than the radius of the rotating shaft. The motor is provided with a speed adjusting system, and communicates with the inductor 13 through a program and a circuit. When the fire hose is wound, the motor speed is set to be fast. Since the water hose reel is small, the inductor 13 cannot sense the existence of the water hose reel. When the fire hose is wound for many turns, the water hose reel becomes large, the load of the motor also increases, and the motor must be slowed down under high load operation to protect the motor and prevent overload. When the water hose reel becomes large enough to be located in the sensing area of the inductor 13, the inductor 13 senses the existence of the water hose reel and sends a signal to slow down the driving motor. The setting can realize fast storage or measurement, and the motor speed gradually slows down as the diameter of the water hose reel increases. When the storage or measurement is completed, the motor is automatically stopped under the control of the load sensor.

[0039] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. The present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
