Description

Technical Field

[0001] The invention relates to the technical field of voltage stabilizers, and in particular to a mobile voltage regulator. Background Art

[0002] A voltage stabilizer (also known as a voltage regulator) is a device that stabilizes the output voltage. One type of voltage stabilizer is one that adjusts the position of the carbon brush to change the coil turns ratio to maintain a stable output voltage, for example: a voltage stabilizer with intelligent protection function applied by the applicant on January 21, 2022.

[0003] As we all know, carbon brushes are consumables and are made of relatively soft materials. During long-term use, the carbon brushes are prone to wear due to friction, which will form impurities inside the body (that is, the shell) of the voltage stabilizer, affecting the use of the voltage stabilizer. The existing methods require the body of the voltage stabilizer to be opened for cleaning, which is very inconvenient.

[0004] Secondly, in order to facilitate movement, the existing voltage stabilizer has running wheels at the bottom of the voltage stabilizer. In order to ensure the smooth movement of the voltage stabilizer, the running wheels need to be cleaned regularly. However, the running wheels are generally set at the bottom of the voltage stabilizer. When cleaning, the running wheels need to be removed, or the voltage stabilizer needs to be tipped over as a whole for cleaning, which is not convenient.

[0017] The present invention has at least the following beneficial effects: 1. The moving wheel of the present invention is supported by the worm gear and is movable, so the circumferential side of the moving wheel (that is, the walking surface of the moving wheel) will not be blocked by the traditional moving wheel bracket. Because of this, the moving wheel of the present invention can be automatically cleaned by the cleaning structure. Therefore, the purpose of cleaning can be achieved without removing the moving wheel or tipping over the entire voltage stabilizer, thereby ensuring smooth movement of the voltage stabilizer.

[0018] 2. When the present invention cleans the moving wheel, the driving structure is used to control the rotation of the worm gear disk, so that the moving wheel can rotate and adjust its posture. In the cleaning posture, the moving direction of the cleaning part is the same as the axial direction of the moving wheel. Therefore, when the cleaning part contacts the moving wheel, impurities on the surface of the moving wheel can be scraped off. In the driving posture, the moving direction of the cleaning part is perpendicular to the axial direction of the moving wheel. Therefore, after the cleaning part contacts the moving wheel, the moving wheel can be driven to rotate, thereby changing the contact position of the moving wheel and the cleaning part in the cleaning posture. Therefore, through the cooperation of the driving structure and the cleaning structure, the moving wheel can be comprehensively cleaned, thereby improving the cleaning effect.

[0019] 3. In order to ensure the stable operation of the voltage stabilizer, the present invention provides a heat dissipation and dust removal device to remove dust from the machine cavity of the voltage stabilizer and to dissipate heat from the voltage stabilizer, namely: In normal heat dissipation (the air intake structure is located below the machine cavity, and the exhaust port is located above the machine cavity): the air intake structure supplies air into the machine cavity and exhausts it from the exhaust port, and the air intake structure and the exhaust port are located at the two farthest positions of the base, so that the air entering the machine cavity can flow inside the machine cavity and fully take away the heat, ensuring the heat dissipation effect; During dust removal: when the air intake structure takes air into the machine cavity, the driving structure is used to control the air intake structure to move back and forth longitudinally, and to "sweep" the pressure regulating device in the machine cavity, so that the impurities are separated from the pressure regulating device, and then the air intake structure is controlled to move to a high position. The exhaust port is now located at a low position. When the air intake structure is started, the impurities can be discharged from the exhaust port, and the exhaust port at a low position is more conducive to the discharge of impurities.

[0020] 4. When the present invention dissipates heat efficiently, the air intake structure can be driven to move back and forth longitudinally and supply air to the pressure regulating device. When the air intake structure moves, the position of the exhaust port is also changed in real time, so that the hot air in different areas of the machine cavity can be discharged, thereby achieving efficient heat dissipation.

[0021] 5. In order to ensure the stability of the moving wheel and the cleaning of the machine cavity, the present invention can use a vertical pole to support the machine body, so that the moving wheel floats in the air, which makes it easier to clean the moving wheel. At the same time, the electric push rod can be used to control the support rod to press the vertical pole to avoid shaking of the vertical pole, thereby making the supporting process more stable.

[0022] 6. The present invention can be moved by means of a handrail, and the handrail can adjust the angle between the handrail and the ground by controlling the air intake structure, so that different users can more conveniently pull the stabilizer to move; moreover, the filtering structure arranged on the handrail can prevent impurities from being directly discharged during heat dissipation, thereby protecting the environment.

[0023] In addition, other advantages of the present invention will be shown in the embodiment of the present invention, thereby making the beneficial effects of the present invention more significant. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In this embodiment: the driving structure includes: The longitudinal drive shaft 40 is rotatably connected to the lower body 101 through a motor (not shown in the figure, which can be installed on the lower body 101); At least two second pulleys 41, respectively mounted on the longitudinal drive shaft 40 and connected to any first pulley 30 via a transmission shaft; A second transmission belt 42 is transmission-connected between the second pulleys 41; A plurality of horizontal drive shafts 43 are rotatably disposed on the lower body 101 and correspond to the worm gears, and a worm 44 cooperating with the worm wheel 21 is mounted at one end of the horizontal drive shaft 43; A first bevel gear 45 is mounted on the longitudinal drive shaft 40; A plurality of second bevel gears 46 are respectively mounted on each horizontal driving shaft 43 and mesh with the first bevel gear 45 .

[0034] In this embodiment: the longitudinal drive shaft 40 includes: The first shaft 401 is provided with the second pulley 42; The second shaft 402 is equipped with the first bevel gear 45; Among them, the mating ends of the first shaft body 401 and the second shaft body 402 are respectively provided with a transmission groove 403 and a transmission block 404 that are adapted to each other, and a plurality of grooves 404a are provided on the circumferential side wall of the transmission block 404, and a one-way support block 404b is hinged in each groove 404a, and a clamping spring 404c is provided between the one-way support block 404b and the groove 404a, and a one-way support groove 403a adapted to the one-way support block 404b is provided on the circumferential groove wall of the transmission groove 403.

[0035] In this embodiment: a vertical rod 101a is hinged on the lower body 101.

[0036] refer to Figure 1-Figure 6 , the principle of this embodiment is: When moving, the chassis is pushed and the moving wheel body can be used to move the body. The moving wheel is composed of a worm wheel disc rotatably arranged on the lower body and a wheel body rotatably connected to the worm wheel disc, so that the chassis can be turned when moving.

[0037] When cleaning the moving wheel, the lower body is supported by the vertical rod, and the moving wheel is separated from the ground, the first shaft of the longitudinal drive shaft is driven by the motor to reciprocate clockwise and counterclockwise, and the first pulley is driven by the second pulley and the second transmission belt to rotate alternately clockwise or counterclockwise, so that the cleaning part reciprocates between adjacent first pulleys; When the cleaning part moves and contacts the wheel body, the wheel body can be cleaned, thereby achieving the purpose of cleaning.

[0038] In order to further improve the cleaning effect of the moving wheel, the longitudinal drive shaft of this embodiment is composed of a first shaft body and a second shaft body. Figure 6 Due to the transmission blocks and transmission grooves arranged on the first shaft body and the second shaft body, when the first shaft body rotates clockwise, the second shaft body will not be transmitted, and when the first shaft body rotates counterclockwise, the first shaft body drives the second shaft body to rotate with the help of the one-way support block, thereby achieving the transmission purpose, wherein the first shaft body that rotates clockwise and counterclockwise can drive the first pulley to rotate through the second pulley, thereby ensuring the reciprocating movement of the cleaning part, and the second shaft body that can only rotate counterclockwise drives the worm gear of each moving wheel to rotate in one direction through the cooperation of the first bevel gear and the second bevel gear, thereby avoiding repeated cleaning of the same position of the wheel body when cleaning the wheel body, thereby ensuring the comprehensiveness of the cleaning of the wheel body.

[0039] In summary, when the worm wheel rotates, the wheel body on the worm wheel will switch between the cleaning position or the driving position. In the cleaning position (refer to Figure 2 When the cleaning part contacts the wheel body of the moving wheel, the moving direction of the cleaning part is contrary to the rotation direction of the wheel body. Therefore, the impurities on the surface of the wheel body can be scraped off with the help of the scraper, and the cleaning brush and other scrapers can be used to complete the secondary cleaning; In the driving pose (ref. Figure 2 When the cleaning part contacts the wheel body of the moving wheel, since the moving direction of the cleaning part is consistent with the rotation direction of the wheel body, when the scraper or cleaning brush of the cleaning part contacts the moving wheel, the moving wheel will be driven to rotate, thereby changing the position where the moving wheel contacts the cleaning part in the cleaning posture, so as to completely clean the circumferential side wall of the wheel body.

[0040] Embodiment 2 is different from Embodiment 1 in that: like Figure 1-Figure 2 as well as Figure 7-10 As shown, in this embodiment: the upper body 100 includes: The main body 50 has the machine cavity 51 and is detachably connected to the lower body 101. A limit frame 50a is provided at the bottom of the main body 50 of this embodiment, and a bolt hole 50b is provided on the limit frame 50a. The lower body 101 is also provided with a limit frame 50a. When the upper body and the lower body are assembled, the limit frames of the two are staggered (that is, they are staggered inside and outside, and the connection is completed by bolts passing through the bolt holes); A heat dissipation port 52 is formed on the side wall of the body 50; A heat dissipation and dust removal device is installed at the heat dissipation port 52; The heat dissipation and dust removal device is composed of a base 6 rotatably arranged at the heat dissipation port 52, an airflow structure installed on the base 6, an air intake structure capable of lifting and moving and driving the base 6 to rotate, and a screw structure for driving the air intake structure to lift and move; The screw of the screw structure can be driven to rotate by the first pulley 30 and control the reciprocating lifting and lowering movement of the air intake structure in the machine cavity 51 .

[0041] In this embodiment: the base 6 includes: The base 60 is rotatably mounted at the heat dissipation port 52, and the outer wall of the base 60 and the inner wall of the heat dissipation port 52 are provided with an annular slide groove 61 and an annular slide rail 62 that are adapted to each other, and the annular slide rail 62 can enable the base 60 to rotate coaxially at the heat dissipation port 52; A mounting cavity 63, an eccentric depression provided on the base 60; An air inlet cavity 64, a coaxial depression provided on the base body 60; A filter screen 65 is disposed in the air inlet cavity 64; A filter cover 66 is detachably mounted on the base body 60 and covers the air inlet cavity 64, and an air inlet 67 is disposed on the filter cover 66; The exhaust port 68 is eccentrically disposed on the base body 60 and is disposed through the base body 60; The installation cavity 63 and the exhaust port 68 are symmetrically arranged.

The screw rods 70 are circumferentially equidistantly distributed in the machine cavity 51. The screw bearing seat 71 is mounted on each screw 70; One end of each screw rod 70 passes through the upper body 100, and is rotatably connected to a driven gear 73 that cooperates with the end of the screw rod 70 on the lower body 101. A driving gear 74 that meshes with the driven gear 73 is coaxially mounted on the transmission shaft of the first pulley 30. A driven groove 73a is provided on the driven gear 73, and one end of the screw rod 70 is adapted to the driven groove 73a. When one end of the screw rod 70 cooperates with the driven groove 73a, the screw rod can rotate with the driven gear. The diameter of the driving gear in this embodiment can be larger than the diameter of the driven gear. Therefore, when the first pulley rotates, the large gear drives the small gear to cooperate, so that the stroke of the screw rod driving the screw rod bearing seat to move back and forth longitudinally can be matched with the stroke of the first pulley driving the cleaning part to move back and forth horizontally.

[0043] The air intake structure of this embodiment includes: The gas inlet 80 is mounted on the screw bearing seat 71 and is located between adjacent screws 70; The air inlet cavity 81 is formed in the air inlet 80 and communicates with the air inlet cavity 64 through the air inlet pipe 82; The air inlet 80 is equipped with a plurality of exhaust fans 83, and is rotatably connected to a driving body 84 in the installation cavity 63, wherein the driving body 84 is provided with a slide groove for the air inlet 80 to slide; A guide body 85 is detachably mounted on the top of the machine cavity 51 by means of screws 85a. The guide body 85 has a guide cavity 86, and a gas inlet end 87 (a gas inlet provided on the side wall of the guide body 85 and connected to the guide cavity 86) that can communicate with the gas inlet 80 is provided on the side wall of the guide body 85. An exhaust end 88 (an exhaust port provided at the bottom of the guide body 85) is provided at the bottom of the guide body 85. The guide body 85 can guide the gas discharged from the gas inlet 80 to flow longitudinally from top to bottom. When the air intake 80 is raised or lowered, the base 60 is controlled to rotate by the driving body 84 .

[0044] In this embodiment: the airflow structure includes: The support rod 90 is mounted on the base 60 through a first connecting column 91 and a second connecting column 92 which are arranged at intervals, wherein the second connecting column 92 is connected to the exhaust port 68 to form an exhaust cavity 92a; A rod cavity is formed in the support rod 90 and is provided through one end close to the second connecting column 92; The filter element 94 is installed in the rod cavity and defines a filter cavity 94a in the rod cavity that communicates with the exhaust cavity 92a. A support rod 95 is slidably disposed in the rod cavity, and one end of the support rod 95 passes through the filter element 94 coaxially, and a press plug 95a is connected to one end of the support rod 95; An electric push rod 96 is installed in the rod cavity to drive the support rod 95 to move, and an air outlet 95b connected to the chamber in the center of the filter element 94 is formed on the pressure plug 95a. The gas exhausted from the chassis is filtered by the filter element and then discharged from the air outlet.

[0045] In this embodiment: the lower body 101 is hinged with a vertical rod 101a, and the vertical rod 101a and the outer side wall of the lower body 101 are respectively provided with mutually adapted clamping protrusions 101b and clamping grooves 101c. When the vertical rod is folded, the vertical rod can be limited to the side wall of the lower body by the clamping protrusions and the clamping grooves, so that the chassis can be moved smoothly; One end of the vertical rod 101a is recessed to form a positioning groove 101d adapted to the pressing plug 95a.

[0046] The principle of this embodiment is: 1. The heat dissipation principle is: when dissipating heat, the air inlet is located at the bottom of the machine cavity. After the induced draft fan is started, the airflow is introduced from the air inlet cavity (the air is filtered by the filter in the air inlet cavity) and introduced from each induced draft fan on the air inlet and sent to the machine cavity. After dissipating heat to the pressure regulating device, it is directly discharged from the exhaust port on the top to complete the heat dissipation; 1.1 Another heat dissipation method of this embodiment is: when dissipating heat, the screw drives the intake gas to move up and down in the machine cavity, and enables the airflow to dissipate heat to the pressure regulating device in all directions. When the intake gas moves, the base also rotates, thereby changing the position of the exhaust port, so that the exhaust port can discharge the heat in the machine cavity from different positions, thereby improving the heat dissipation effect. This action can also make the impurities flowing with the airflow in the machine cavity be gradually gathered in the filter cavity, and the purpose of dust removal is achieved simultaneously.

[0047] 2. Dust removal principle: During dust removal, the intake air performs reciprocating lifting and lowering activities, and first removes dust from the pressure regulating device, so that impurities are separated from the pressure regulating device, and the intake air moves to the top position of the machine cavity to cooperate with the drainage body (so that the gas discharged from the intake air enters the drainage cavity, and then is discharged from the exhaust end on the drainage body). At this time, the exhaust port is located at the bottom position of the machine cavity (which can make it easier to discharge impurities and make it more convenient to clean the pressure plug). At this time, the intake air supplies air to the drainage cavity, and the airflow is guided by the drainage cavity to flow from top to bottom, and guides the impurities in the machine cavity to be discharged from the exhaust port to complete the dust removal.

[0048] It should be noted that: during dust removal, when the exhaust port moves to the bottom position of the machine cavity, the electric push rod controls the pressure plug to open the rod cavity, and makes the pressure plug fit into the positioning groove on the vertical pole, thereby pressing the vertical pole to prevent the vertical pole from shaking and ensure stability. The impurities discharged from the exhaust port will be discharged from one end of the rod cavity to complete the dust removal.

[0049] During heat dissipation, the rod cavity is sealed by a plug, so that when heat is dissipated, impurities flowing with the air flow will be gathered in the filter cavity, thereby preventing the impurities from being directly discharged and causing environmental pollution.

[0050] It is worth mentioning that the air intake structure and the cleaning part of the lower body of this embodiment can be controlled synchronously, so that the dust removal and cleaning of the moving wheel and the machine cavity can be carried out synchronously. Secondly, the air intake of this embodiment is not only used for dust removal, but also for heat dissipation. According to the heat generation position of the pressure regulating device, the original air intake can be adjusted from horizontal air supply to vertical air supply, thereby better cooling the pressure regulating device.
