[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to Figures 1-4 , an embodiment provided by the present utility model: a concrete vibrator with overload and open-phase protection, including a fixed frame 1 and a concrete controller body 14. The concrete controller body 14 includes a three-phase asynchronous motor body 5, a transmission hose 6, a vibrating rod 7, a locking rotating handle 8, a control device body 9, an indicator light 10, a fixed pipe 12, and a cable 13. A fixing plate 2 is fixedly connected to the fixed frame 1, a mounting plate 3 is fixedly connected to the fixing plate 2, and a connecting plate 4 is fixedly connected to the fixing plate 2. The three-phase asynchronous motor body 5 is fixedly connected to the mounting plate 3. The transmission hose 6 is detachably connected to the three-phase asynchronous motor body 5. The vibrating rod 7 is fixedly connected to one end of the transmission hose 6 away from the three-phase asynchronous motor body 5. The locking rotating handle 8 is rotatably connected to the three-phase asynchronous motor body 5. By incorporating an overload and open-phase protection mechanism in the concrete vibrator, with three-in-three-out internal three sets of wire harnesses, and through the control device to monitor the operating state of the motor in real time, once an abnormal situation is detected, such as motor overload or power supply open-phase, the system will immediately cut off the power supply, effectively preventing safety accidents that may be caused by motor overheating and damage, and ensuring the safety of construction personnel.

[0028] The control device body 9 is fixedly connected to the three-phase asynchronous motor body 5. The indicator light 10 is provided on one side of the control device body 9. The fixed pipe 12 is provided on the control device body 9. The cable 13 passes through the fixed pipe 12 and is connected to the inside of the control device body 9. The vibrating rod 7 is inserted into the concrete. One end of the cable 13 is connected to the power supply. Rotating the locking rotating handle 8 fixes the transmission hose 6 to the three-phase asynchronous motor body 5. There are two sets of fixed frames 1 and connecting plates 4 respectively, providing a stable support structure for the entire vibrator. The fixed frame 1 is connected to the mounting plate 3 through the fixing plate 2, ensuring the stability and reliability of the vibrator during operation.

[0029] Working principle: One end of the cable 13 is connected to an external power supply to provide power support for the entire system. The cable 13 passes through the fixed pipe 12 and is connected to the control device body 9. The three internal wire harnesses are three-in and three-out to ensure the safety and stability of power transmission. The control device body 9 is fixedly connected to the three-phase asynchronous motor body 5, responsible for receiving power signals and performing control processing. The indicator light 10 is arranged on one side of the control device body 9 to display the working state of the device, such as normal operation, overload, phase loss, etc., so that the operator can timely understand the device status. The three-phase asynchronous motor body 5 is the power source of the entire vibrator and is stably installed by being fixedly connected to the mounting plate 3. When the power is turned on and started, the motor starts to run and generates a driving force. The transmission hose 6, as a key component connecting the motor and the vibrating rod 7, adopts a detachable connection method for easy maintenance and replacement. By rotating the locking handle 8, it can ensure that the transmission hose 6 is firmly connected to the three-phase asynchronous motor body 5 to prevent loosening or falling off. The vibrating rod 7 is fixedly connected to the end of the transmission hose 6 away from the motor. When the motor runs, the power is transmitted to the vibrating rod 7 through the transmission hose 6, causing it to generate high-frequency vibration and insert into the concrete. This vibration effect can effectively remove the air bubbles in the concrete and enhance the density and uniformity of the concrete. The control device internally is equipped with an intelligent monitoring circuit that can real-time detect the operating state of the motor. Once an overload or phase loss situation is detected, the control device will immediately cut off the power supply and send a warning signal through the indicator light 10 to protect the motor from damage and prevent the occurrence of safety accidents. There are two groups of fixed frames 1 and connecting plates 4 respectively, providing a stable support structure for the entire vibrator. The fixed frame 1 is connected to the mounting plate 3 through the fixing plate 2 to ensure the stability and reliability of the vibrator during operation.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
