Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, and in particular to an electric push rod ball valve switch control device. Background Technology

[0002] Road maintenance and cleaning vehicles are equipped with various water spraying devices, such as front sprayers, side sprayers, high-pressure flushing nozzles, and manual high-pressure spray guns. Therefore, the water outlet pipe inside the vehicle branches into multiple branch pipes, each connected to a different spraying device, and the opening and closing of each branch pipe is controlled by a ball valve. If workers had to leave the cab to manually operate the ball valves, the workflow would be complex, and operational safety could not be guaranteed. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides an electric push rod ball valve switching control device, which uses an electric push rod to drive the control handle to move the ball valve, replacing the manual opening and closing of the ball valve.

[0004] Technical Solution: To achieve the above objectives, this utility model provides an electric push rod ball valve switch control device, comprising a vertical frame and a distribution pipe. A horizontal frame is connected to one side of the vertical frame, and the distribution pipe is placed on the horizontal frame. The distribution pipe is connected to several branch pipes, and each branch pipe is equipped with a ball valve. The control handles connected to each ball valve extend towards the vertical frame. Several electric push rods are suspended on the vertical frame, and each electric push rod corresponds to a ball valve. The output end of the electric push rod is connected downward to the control handle. When the electric push rod extends or retracts, it drives the control handle to actuate the ball valve.

[0005] Furthermore, the upper end of the electric push rod is hinged to the upright, the lower end of the electric push rod is hinged to one end of the control handle, and the other end of the control handle is fixedly connected to the valve core of the ball valve.

[0006] Furthermore, the rotation plane of the electric actuator and the rotation plane of the control handle are in the same vertical plane.

[0007] Furthermore, the control handle is a crank, and a strain sensor is provided on the control handle, which can measure the bending change of the control handle.

[0008] Furthermore, the control handle has a downward-curving arc-shaped connecting portion; the strain sensor is a strain gauge, which is correspondingly attached to the inner curve above the arc-shaped connecting portion.

[0009] Furthermore, a crossbeam is provided on the upright frame, and several hinge seats are arranged below the crossbeam. The upper end of the electric push rod is hinged to the hinge seat.

[0010] Furthermore, the bottom of the distribution tube is flat, and a fixing cover is provided on the cross frame. The fixing cover presses onto the distribution tube so that the bottom of the distribution tube is close to the cross frame.

[0011] Beneficial effects: The electric push rod ball valve switch control device of this utility model has the following beneficial effects:

[0012] 1) A ball valve is installed on the branch pipe of the distribution pipe; the upper end of the electric push rod is hinged to the upright, and the lower end of the electric push rod is hinged to the control handle. The extension and retraction of the electric push rod can be remotely controlled by an electrical signal, which in turn drives the control handle to move the ball valve, so as to replace the manual opening and closing of the ball valve.

[0013] 2) The control handle is a crank, and strain gauges are attached to the bending part of the control handle. The strain gauges are used to detect the force on the control handle, thereby determining whether the valve core of the ball valve has rust, jamming or other faults, and preventing the electric push rod from being forcibly extended and retracted and damaged in the event of a valve core failure. Attached Figure Description

[0014] Appendix Figure 1 This is a schematic diagram of the overall structure of this utility model. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] As attached Figure 1 The electric push-rod ball valve switch control device includes a vertical frame 1 and a distribution pipe 3. A horizontal frame 2 is connected to one side of the vertical frame 1, and the distribution pipe 3 is placed on the horizontal frame 2. The horizontal frame 2 includes two opposing support plates, and the two ends of the distribution pipe 3 are respectively placed on the two support plates. Several branch pipes 9 are connected to the bottom of the distribution pipe 3, and the branch pipes 9 extend downward from between the two support plates. Each branch pipe 9 is equipped with a ball valve 8, which is used to control the opening and closing of each branch pipe 9. In practical applications, one end of the distribution pipe 3 is connected to a water supply device through a pipeline. The water supply device supplies water to the distribution pipe 3, and then the distribution pipe 3 distributes the water to each branch pipe 9.

[0017] The valve core of ball valve 8 is connected to control handle 7 via valve stem, and the control handle 7 connected to each ball valve 8 extends towards the support frame 1. Several electric actuators 4 are suspended on the support frame 1. Each electric actuator corresponds to each ball valve 8. The output end of the electric actuator is connected downward to the control handle 7. When the electric actuator extends or retracts, it drives the control handle 7 to actuate the ball valve 8, thereby controlling the opening and closing of the ball valve 8.

[0018] In this invention, the extension and retraction of the electric push rod can be remotely controlled by an electrical signal to replace the manual opening and closing of the ball valve 8, thereby controlling the water flow of each branch pipe 9.

[0019] The upper end of the electric actuator is hinged to the support frame 1, and the lower end of the electric actuator is hinged to one end of the control handle 7. The other end of the control handle 7 is fixedly connected to the valve core of the ball valve 8. During the extension and retraction of the electric actuator, the angle of the control handle 7 relative to the ball valve 8 changes, and correspondingly, the electric actuator itself will swing on the support frame 1 to adapt to the angle change of the control handle 7. If the upper end of the electric actuator is fixedly connected to the support frame 1, there will be motion interference between the electric actuator and the control handle 7.

[0020] The rotation plane of the electric push rod and the rotation plane of the control handle 7 are in the same vertical plane so that the force of the electric push rod can be transmitted to the control handle 7.

[0021] The control handle 7 is a crank, and a strain sensor is installed on the control handle 7 to measure the bending change of the control handle 7. Under normal circumstances, if the ball valve 8 is not obstructed, during the rotation of the ball valve 8, the valve core will only strike the limiting component inside the ball valve 8 at the moment of opening or closing, thereby generating a reverse force and causing a change in the bending degree of the control handle 7, thus changing the measurement value of the strain sensor. However, if the ball valve 8 is obstructed due to factors such as rust or foreign objects, the valve core will generate additional force due to the obstruction during the rotation of the ball valve 8, thereby causing the control handle 7 to bend. By detecting the additional bending change by the strain sensor, it can be determined whether the ball valve 8 is obstructed. Preferably, the control handle 7 has a downward-curved arc-shaped connecting part 11. The strain sensor is a strain gauge, which is attached to the inner bend above the arc-shaped connecting part 11, and the strain gauge is not easy to fall off the control handle 7.

[0022] A crossbeam 6 is also provided on the upright frame 1, and several hinge seats 5 are arranged below the crossbeam 6. The upper end of the electric push rod is hinged to the hinge seat 5.

[0023] The bottom of the distribution pipe 3 is flat, and a fixing cover 10 is provided on the cross frame 2. The fixing cover 10 covers the distribution pipe 3 so that the bottom of the distribution pipe 3 is close to the cross frame 2.

[0024] In one embodiment, the automatic control device for the ball valve 8 of this invention is applied to a road maintenance and cleaning vehicle. The support frame 1 is fixedly installed inside the vehicle compartment, where a water tank serves as the water supply system, with a high-pressure water pump delivering water to the distribution pipe 3. Each branch pipe 9 on the distribution pipe 3 is connected to different water spraying devices on the road maintenance and cleaning vehicle. An electronic screen is installed in the driver's cab, connected to a controller. Workers operate the system via the electronic screen, sending commands to the controller, which then controls the extension and retraction of each electric actuator, thereby adjusting the opening degree of each ball valve 8. Thus, workers do not need to leave the driver's cab to manually open and close the ball valves 8, thereby improving operational safety and simplifying the workflow.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
