Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a high-efficiency and energy-saving motor speed control device. Background Technology

[0002] Electric motors, as the core equipment for converting electrical energy into mechanical energy, play an irreplaceable and crucial role in modern industry and daily life. They are commonly used in electric vehicles, precision machine tools, and other applications. AC motors are simple in structure and reliable in operation, and are widely used in industrial fans, water pumps, and household appliances. From robotic arms on industrial production lines to fans and washing machines in homes, motors are ubiquitous, continuously injecting strong power into the automation and intelligentization processes of various fields. Motor speed control devices are diverse in type and function. For DC motor speed control, there are thyristor speed controllers, which adjust the armature voltage by changing the thyristor firing angle and have strong overload capacity.

[0003] However, most existing speed controllers have exposed terminals, which may come into contact with other conductors, causing short circuits, burning out the speed controller or motor, or even causing serious consequences such as electrical fires. At the same time, dust, moisture and other impurities can easily enter the terminals, causing poor contact, making the speed controller work unstable and causing problems such as motor speed fluctuations. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of exposed terminals of existing speed controllers, which may come into contact with other conductors, causing short circuits, burning out the speed controller or motor, or even causing serious consequences such as electrical fires. At the same time, dust, water vapor and other impurities can easily enter the terminals, resulting in poor contact, unstable operation of the speed controller and fluctuations in motor speed. Therefore, this utility model proposes a high-efficiency and energy-saving motor speed control device.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency and energy-saving motor speed control device, including a speed controller and a protection device. One end of the speed controller is equipped with a terminal block. The protection device is disposed on the surface of the speed controller and includes a column fixedly connected to the speed controller. A threaded rod is fixedly connected to the upper surface of the column. A retaining sleeve is fitted onto the upper surface of the terminal block. A cylinder is fixedly connected to one side of the retaining sleeve. The cylinder, threaded rod, and column are fitted together. A retaining wall is fixedly connected to the surface of the retaining sleeve. A knob is threadedly connected to the surface of the threaded rod. By setting up the protection device, after wiring is completed, rotating the knob in the opposite direction allows the retaining sleeve and retaining wall to tightly fit the terminal block, forming a relatively enclosed space. This effectively prevents external dust, moisture, foreign objects, etc., from entering, reducing damage to the terminal block due to moisture, corrosion, short circuits, etc., and extending the service life of the terminal block.

[0006] Preferably, the knob contacts the cylinder, and there are multiple barriers arranged in a linear array. By rotating the knob to move it upward, the constraint on the cylinder can be released. At this time, the elastic force of the pressure spring is released, which in turn squeezes the cylinder and drives the sleeve to rise, thereby opening the terminal and creating conditions for wiring operations. This provides sufficient space for the operator to easily connect the wire to the terminal.

[0007] Preferably, a pressure spring is fitted on the surface of the column. The two ends of the pressure spring are fixedly connected to the speed controller and the cylinder, respectively. By setting the pressure spring, when the knob is turned to move it upward, the cylinder is unrestrained. At this time, the pressure spring releases the stored elastic potential energy and generates elastic force. This elastic force will squeeze the cylinder. Since the sleeve is connected to the cylinder, under the action of the pressure spring, the cylinder will drive the sleeve to rise upward, thereby opening the terminal and providing the necessary space for wiring operation, so that the operator can smoothly connect the wire to the terminal.

[0008] Preferably, a clamping device is provided on one side of the speed controller. The clamping device includes a fixed sleeve, which is fixedly connected to the speed controller. A push plate is slidably connected to the inner wall of the fixed sleeve, and a pressure block is fixedly connected to the surface of the push plate. By setting the clamping device, after the power cord passes through the fixed sleeve, the clamping device plays its role. The fixed spring generates elastic force to squeeze the push plate, and the push plate drives the pressure block to firmly press the power cord in a specific position. This ensures that the power cord remains fixed during and after wiring, preventing the power cord from moving due to external pulling, vibration, etc., ensuring a stable connection between the power cord and the terminal, reducing problems such as poor contact and arcing that may be caused by loose power cords, and ensuring the normal operation of the circuit.

[0009] Preferably, the fixing sleeve is located below the terminal block, and the surface of the fixing sleeve has a wire through hole.

[0010] Preferably, a pull rod is fixedly connected to one end of the push plate, and there are multiple pressure blocks. The pressure blocks correspond to the wire holes. By setting the pressure blocks, the pressure blocks directly contact the power cord and apply pressure under the force transmitted by the fixed spring through the push plate. Through this direct physical action, the power cord is firmly fixed in a specific position to prevent it from moving during or after wiring.

[0011] Preferably, a fixing spring is fixedly connected to the surface of the push plate. The end of the fixing spring away from the push plate is fixedly connected to the fixing sleeve. By setting the fixing spring, the main function of the fixing spring is to generate elastic force. When the pull rod is released, the elastic force generated by it can squeeze the push plate, thereby driving the pressure block to press the power cord tightly. This elastic force is the key power source for fixing the power cord, ensuring that the power cord remains stable after being connected and will not easily loosen.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this utility model, by setting up a protective device and a clamping device, when in use, rotating the knob moves the knob upward, at which point the cylinder is unrestrained, and the pressure spring generates elastic force to squeeze the cylinder and drive the sleeve to rise, opening the terminal and allowing for wiring. After wiring is completed, rotating the knob in the opposite direction moves the knob downward, squeezing the cylinder at the same time. The cylinder drives the sleeve and the guard to cover the terminal, which is convenient for protecting the terminal. When wiring, the power cord is passed through the fixed sleeve and the pull rod is released. The fixed spring generates elastic force to squeeze the push plate and drive the pressure block to press the power cord tightly, reducing the possibility of the power cord becoming loose.

[0014] By incorporating this utility model, after wiring is completed, rotating the knob in the opposite direction allows the sleeve and enclosure to tightly fit the wiring terminal, forming a relatively enclosed space. This effectively prevents external dust, moisture, foreign objects, etc. from entering, reducing damage to the wiring terminal due to moisture, corrosion, short circuits, etc., and extending the service life of the wiring terminal.

[0021] Please see Figures 1-5This utility model provides a technical solution: a high-efficiency and energy-saving motor speed control device, including a speed controller 1 and a protection device 3. One end of the speed controller 1 is equipped with a terminal 2, and the protection device 3 is disposed on the surface of the speed controller 1.

[0022] The specific settings and functions of its protection device 3 and clamping device 4 will be explained below.

[0023] In this implementation scheme: the protection device 3 includes a column 37, which is fixedly connected to the speed controller 1. A threaded rod 34 is fixedly connected to the upper surface of the column 37. A retaining sleeve 31 is fitted onto the upper surface of the terminal 2. A cylinder 33 is fixedly connected to one side of the retaining sleeve 31. The cylinder 33 is fitted onto the threaded rod 34 and the column 37. A retaining wall 32 is fixedly connected to the surface of the retaining sleeve 31. A knob 35 is threaded onto the surface of the threaded rod 34. By setting the protection device 3, after wiring is completed, rotating the knob 35 in the opposite direction can tightly fit the retaining sleeve 31 and the retaining wall 32 onto the terminal 2, forming a relatively closed space. This can effectively prevent external dust, moisture, foreign objects, etc. from entering, reduce damage to the terminal 2 due to moisture, corrosion, short circuits, etc., and extend the service life of the terminal 2.

[0024] Specifically, the knob 35 contacts the cylinder 33, and there are multiple barriers 32 arranged in a linear array. By rotating the knob 35 to move it upward, the constraint on the cylinder 33 can be released. At this time, the elastic force of the pressure spring 36 is released, which in turn squeezes the cylinder 33 and drives the sleeve 31 to rise, thereby opening the terminal 2, creating conditions for wiring operation, and providing enough space for the operator to easily connect the wire to the terminal 2.

[0025] Specifically, a pressure spring 36 is fitted on the surface of the column 37. The two ends of the pressure spring 36 are fixedly connected to the speed controller 1 and the cylinder 33, respectively. By setting the pressure spring 36, when the knob 35 is rotated to move it upward, the cylinder 33 is unrestrained. At this time, the pressure spring 36 releases the stored elastic potential energy and generates elastic force. This elastic force will squeeze the cylinder 33. Since the sleeve 31 is connected to the cylinder 33, under the action of the elastic force of the pressure spring 36, the cylinder 33 will drive the sleeve 31 to rise upward, thereby opening the terminal 2 and providing the necessary space for wiring operation, so that the operator can smoothly connect the wire to the terminal 2.

[0026] Specifically, a clamping device 4 is provided on one side of the speed controller 1. The clamping device 4 includes a fixed sleeve 41, which is fixedly connected to the speed controller 1. A push plate 43 is slidably connected to the inner wall of the fixed sleeve 41, and a pressure block 42 is fixedly connected to the surface of the push plate 43. By setting the clamping device 4, after the power cord passes through the fixed sleeve 41, the clamping device 4 plays its role. The fixed spring 44 generates elastic force to squeeze the push plate 43. The push plate 43 drives the pressure block 42 to press the power cord tightly in a specific position, so that the power cord can remain fixed during the wiring process and after the wiring is completed. This avoids the power cord from moving due to external pulling, vibration, etc., and ensures the stable connection between the power cord and the terminal 2. It also reduces problems such as poor contact and arcing that may be caused by loose power cords, and ensures the normal operation of the circuit.

[0027] Specifically, the fixing sleeve 41 is located below the terminal 2, and the surface of the fixing sleeve 41 is provided with a wire through hole.

[0028] Specifically, a pull rod 45 is fixedly connected to one end of the push plate 43, and there are multiple pressure blocks 42, which correspond to the wire holes.

[0029] In this embodiment: by setting up a pressure block 42, the pressure block 42 directly contacts the power cord and applies pressure under the force transmitted by the fixed spring 44 through the push plate 43. Through this direct physical action, the power cord is firmly fixed in a specific position to prevent it from moving during or after wiring.

[0030] Specifically, a fixing spring 44 is fixedly connected to the surface of the push plate 43, and the end of the fixing spring 44 away from the push plate 43 is fixedly connected to the fixing sleeve 41.

[0031] In this embodiment: By setting a fixed spring 44, the main function of the fixed spring 44 is to generate elastic force. When the pull rod 45 is released, the elastic force generated by it can squeeze the push plate 43, thereby driving the pressure block 42 to press the power cord tightly. This elastic force is the key power source for fixing the power cord, ensuring that the power cord remains stable after being connected and will not easily loosen.

[0032] Working principle: By setting up the protection device 3 and the clamping device 4, during use, rotating the knob 35 causes it to move upwards. At this time, the cylinder 33 is unrestrained, and the pressure spring 36 generates elastic force to squeeze the cylinder 33 and drive the clamping sleeve 31 to rise, opening the terminal 2 for wiring. After wiring is completed, rotating the knob 35 in the opposite direction causes it to move downwards, squeezing the cylinder 33. The cylinder 33 drives the clamping sleeve 31 and the retaining wall 32 to cover the terminal 2, facilitating protection of the terminal 2. During wiring, the power cord... After passing through the fixing sleeve 41 and releasing the pull rod 45, the fixing spring 44 generates elastic force to squeeze the push plate 43 and drive the pressure block 42 to press the power cord tightly, reducing the possibility of the power cord being loose. By setting up this utility model, after the wiring is completed, by rotating the knob 35 in the opposite direction, the sleeve 31 and the enclosure 32 can be tightly fitted to the terminal 2, forming a relatively closed space, which can effectively prevent external dust, moisture, foreign objects, etc. from entering, reduce the damage to the terminal 2 due to moisture, corrosion, short circuit, etc., and extend the service life of the terminal 2.
