Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an automatic valve switching device. Background Technology

[0002] Valves are divided into automatic on / off valves and manual on / off valves. Manual on / off valves require manual rotation of the handle. For some large manual on / off valves, this can require dozens, hundreds, or even thousands of rotations, which is extremely labor-intensive. Therefore, there is an urgent need to develop an automatic valve on / off device that is easy to install and use, automatically opening and closing manual on / off valves, saving manpower, and overcoming the shortcomings of current applications to meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide an automatic valve switching device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic valve switching device includes a base plate, a switching mechanism, and an automatic switching mechanism. Three switching mechanisms are detachably connected to the outer side of the base plate. Each switching mechanism includes a switching frame, a pin, and a tightening bolt. A pin penetrating the base plate is detachably mounted on the upper end of the switching frame, and a tightening bolt is mounted on the lower end of the switching frame. The automatic switching mechanism is mounted on the base plate and includes a drive motor, a small sprocket, a large sprocket, a chain, a drive shaft, a turntable, and a clamping mechanism. The drive motor is fixed to the base plate. A small sprocket is fixed on the output shaft of the drive motor. The small sprocket is rotatably connected to a large sprocket via a chain. The large sprocket is fixed on a drive shaft, which is rotatably connected to a base plate. The turntable is fixedly connected to the large sprocket. Two clamping mechanisms are detachably installed on the turntable. The clamping mechanisms are used to fix the turntable to a valve handle. Each clamping mechanism includes a fastening bolt, a base plate, and a nut. There are two fastening bolts, which penetrate the base plate. Each fastening bolt has a detachable nut.

[0006] Preferably, the turntable is provided with an arc-shaped groove for fastening bolts to pass through.

[0007] Preferably, the three connecting mechanisms are evenly distributed in a circle with the central axis of the substrate as the reference.

[0008] Preferably, a mobile power supply and a motor controller are mounted on the substrate, the mobile power supply supplies power to the motor controller and the drive motor, and the motor controller controls the drive motor.

[0009] Preferably, a handle is fixed on the substrate.

[0010] The beneficial effects of this utility model are as follows: When using this automatic valve switching device, first remove the clamping mechanism from the turntable and the adapter mechanism from the base plate. Then, place the turntable on top of the valve handle and place the base plate under the valve handle. Next, pass the fastening bolt through the arc-shaped groove and through the base plate. Then, tighten the nut from the bottom of the base plate onto the fastening bolt, thereby fixing the turntable and valve handle together. Then, fix the adapter frame to the base plate using a pin, and then tighten the top bolt to press it against the valve body, thereby fixing the base plate and valve body together. Then, start the drive motor to drive the small sprocket and large sprocket to rotate. The large sprocket drives the turntable to rotate, which in turn drives the valve handle to rotate. The forward and reverse rotation of the drive motor achieves automatic opening and closing of the valve. In summary, this utility model is easy to install and use, and can automatically open and close manually operated valves, saving manpower. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-6 In this embodiment of the present invention, an automatic valve switching device includes a base plate 1, a connecting mechanism 3, and an automatic switching mechanism 4. Three connecting mechanisms 3 are detachably connected to the outer side of the base plate 1. These three connecting mechanisms 3 are evenly distributed in a circle around the central axis of the base plate 1. The connecting mechanisms 3 are used to secure the base plate 1 to the valve body. The automatic switching mechanism 4 is mounted on the base plate 1 and includes: a drive motor 401, a small sprocket 402, a large sprocket 403, a chain 404, a transmission shaft 405, a turntable 406, and a clamping mechanism 407. The drive motor 401 is fixed to the base plate 1. The small sprocket 402 is fixed to the output shaft of the drive motor 401. The small sprocket 402 is rotatably connected to the large sprocket 403 via the chain 404. The large sprocket 403 is fixed to the transmission shaft 405, which is rotatably connected to the base plate 1. The turntable 406 is fixedly connected to the large sprocket 403. Two clamping mechanisms 407 are detachably installed on the turntable 406. The clamping mechanisms 407 are used to fix the turntable 406 to the valve handle. The clamping mechanism 407 includes: fastening bolts 4071, base plate 4072, and nuts 4073. There are two fastening bolts 4071, which pass through the base plate 4072. Each fastening bolt 4071 can be detachably installed with a nut 4073. The turntable 406 is provided with an arc-shaped groove 4061 for the fastening bolts 4071 to pass through. First, the clamping mechanism 407 is removed from the turntable 406. During installation, the base plate 4072 is placed under the valve handle. Then, the fastening bolts 4071 are passed through the arc-shaped groove 4061 and then through the base plate 4072. Finally, the nuts 4073 are tightened from the underside of the base plate 4072 onto the fastening bolts 4071, thereby fixing the turntable 406 to the valve handle.

[0022] A handle 2 is fixed on the base plate 1, so that the entire device can be lifted away by the handle 2.

[0023] The adapter mechanism 3 includes an adapter frame 301, a pin 302, and a tightening bolt 303. The upper end of the adapter frame 301 is detachably equipped with a pin 302 that penetrates the base plate 1, and the lower end of the adapter frame 301 is equipped with a tightening bolt 303. In use, the adapter frame 301 is first fixed to the base plate 1 by the pin 302, and then the tightening bolt 303 is turned to tighten it onto the valve body, thereby fixing the base plate 1 and the valve body together.

[0024] A mobile power supply 5 and a motor controller 6 are mounted on the base plate 1. The mobile power supply 5 supplies power to the motor controller 6 and the drive motor 401. The motor controller 6 controls the drive motor 401 (the wires in the figure are not shown).

[0025] Working principle: When using this automatic valve switching device, first remove the clamping mechanism 407 from the turntable 406 and the adapter mechanism 3 from the base plate 1. Then, place the turntable 406 on top of the valve handle, and place the base plate 4072 under the valve handle. Next, pass the fastening bolt 4071 through the arc-shaped groove 4061 and then through the base plate 4072. Finally, tighten the nut 4073 from the underside of the base plate 4072 onto the fastening bolt 4071, thereby moving the turntable 406... 6. Fix the valve handle together, then fix the adapter 301 to the base plate 1 through the pin 302, and then tighten the top bolt 303 to press it against the valve body, thereby fixing the base plate 1 and the valve body together. Then, start the drive motor 401 to drive the small sprocket 402 and the large sprocket 403 to rotate. The large sprocket 403 drives the turntable 406 to rotate, and the turntable 406 drives the valve handle to rotate. The forward and reverse rotation of the drive motor 401 realizes the automatic opening and closing of the valve.
