Description

Technical Field

[0001] This utility model belongs to the field of generator control technology, specifically a generator automatic start-stop control device. Background Technology

[0002] Generator sets are power generation equipment provided by some departments to provide emergency power. The generator set control box is an important component of the generator set. The electronic components that control the automatic start and stop of the generator are installed inside the control box, and the box has a protective function for these electronic components.

[0003] A search revealed Chinese Patent Publication No. CN215646642U, which describes a self-starting control box. The box includes a control housing, with a battery and PLC controller installed at the bottom. A generator set is fixedly installed within the control housing, also working in conjunction with the PLC controller. A temperature sensor is installed on the inner wall of the control housing, and a cooling fan is located at the top, working in conjunction with the PLC controller. This invention uses the temperature sensor to detect the internal temperature of the control housing and transmits a command to the PLC controller. The PLC controller then controls the cooling fan to start automatically, thus automatically cooling the generator set and ensuring its normal operation. The PLC controller also detects whether the generator set is receiving power. When there is no power, the PLC controller controls the battery to supply power to the generator set, thus automatically powering the generator set.

[0004] In the aforementioned technology, the device can efficiently dissipate heat from the housing thanks to its designed structure. However, in actual use, the ventilation holes are always open. This allows external moisture to easily enter the housing when heat dissipation is not needed. Especially in rainy or humid weather, the electronic components inside the housing that control the automatic start-stop of the engine are highly susceptible to moisture damage, and may even experience short circuits, resulting in insufficient protection. Therefore, to address these issues, an automatic start-stop control device for a generator is proposed. Utility Model Content

[0026] 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.

[0027] Specific implementation examples are given below.

[0028] Please see Figure 1 - Figure 7This utility model provides an automatic start-stop control device for a generator, including a housing 1; a control door 2 is provided in the middle of the housing 1; a wire release hole 9 is provided at the bottom of the inner wall of the housing 1; an air outlet 7 is provided at the top of the housing 1; an air inlet pipe 6 is fixedly connected to the side wall of the air outlet 7; a fixing plate 34 is fixedly connected to the top of the inner wall of the housing 1; a fan 33 is fixedly connected to the end of the fixing plate 34; a cylindrical tube 311 is installed on the top of the fan 33; and the cylindrical tube 311 is driven by the fan 33; a sliding column 310 slides on the inner wall of the cylindrical tube 311; a protective plate 3 is fixedly connected to the top of the sliding column 310; a connecting plate 31 is fixedly connected to the side wall of the protective plate 3; a second protective plate 32 is fixedly connected to the other end of the connecting plate 31; the side wall of the second protective plate 32 is slidably connected to the end of the air inlet pipe 6; the cylindrical tube 311... The inner wall is provided with a spiral groove 312; the inner wall of the top of the cylindrical tube 311 is provided with an annular groove 313; the spiral groove 312 and the annular groove 313 are connected; a sliding rod 314 is fixedly connected to the side wall of the bottom of the sliding column 310; the sliding rod 314 slides on the inner wall of the spiral groove 312; during operation, the electronic components that automatically control the start and stop inside the housing 1 are connected to an external generator by using a wire. The wire shell passes through the wire release hole 9, and the generator is automatically started by adjusting the components set on the control door 2. The specific operation and wiring process are all existing technologies, which are understood by those skilled in the art, and will not be described here. When the components inside the housing 1 need to dissipate heat during use, the fan 33 can be started to dissipate the heat inside the housing 1. The air is blown out, while the air from the outer wall enters the interior of the housing 1 through the air inlet pipe 6, ensuring rapid heat dissipation inside the housing 1. When the fan 33 starts and drives the fan blades to rotate, the cylindrical tube 311 also rotates accordingly. At this time, the sliding rod 314 slides on the inner wall of the spiral groove 312 through the spiral amplitude of the spiral groove 312. With the amplitude of the spiral groove 312, it will drive the sliding column 310 to rise and open until the sliding rod 314 moves to the inner wall of the annular groove 313. At this time, the cylindrical tube 311 continues to rotate, and the sliding rod 314 can only slide on the inner wall of the annular groove 313. It will not continue to rise or fall. This state is the state where the protective plate 3 is fully open. In addition, when the protective plate 3 moves open... When the connecting plate 31 moves the second protective plate 32, it releases the seal of the second protective plate 32 on the air inlet pipe 6, thus ensuring that the housing 1 can dissipate heat smoothly. After the heat dissipation is completed, the fan 33 can be stopped and started, causing the fan 33 to rotate in the opposite direction. When the sliding rod 314 passes through the connection between the spiral groove 312 and the annular groove 313, it will enter the interior of the spiral groove 312 by gravity and move downward along the amplitude of the spiral groove 312. The subsequent structural cooperation is the same as above. This allows the first protective plate 3 and the second protective plate 32 to close synchronously, ensuring that when ventilation and heat dissipation are not required, external moisture will not take advantage of the situation to enter the interior of the housing 1, thus improving the service life of the electronic components inside the housing 1 that control the automatic start and stop of the engine.

[0029] Furthermore, such as Figure 1 - Figure 2 and Figure 4 - Figure 5 As shown, an annular airbag 44 is fixedly connected to the inner wall of the wire feeding hole 9; a sealing cylinder 4 is provided at the bottom of the box body 1, and a pull rod 42 is slidably connected through the end of the sealing cylinder 4; a piston block 49 is fixedly connected to the end of the pull rod 42; the piston block 49 is piston-connected to the inner wall of the sealing cylinder 4; a one-way valve 43 is installed on the side wall of the end of the sealing cylinder 4; a one-way valve 48 is installed on the side wall of the end of the piston block 49, located on one side of the one-way valve 43; a T-shaped tube 45 is installed on the top of the one-way valve 48; the T-shaped tube 45 is fixedly connected to the inner wall of the bottom end of the box body 1; the other end of the T-shaped tube 45 is installed on the side of the annular airbag 44. During operation, when the cable is passed through the cable release hole 9, the pull rod 42 can be repeatedly pushed and pulled. The pull rod 42 will drive the piston block 49 to move within the inner wall of the sealing cylinder 4. In this way, outside air will enter the interior of the sealing cylinder 4 through the one-way valve 43 and the interior of the T-shaped tube 45 through the one-way valve 48. Then, it will enter the interior of the annular air bladder 44, causing the annular air bladder 44 to expand and compress the cable. This will fill the gap between the cable and the cable release hole 9, improve the sealing effect of the housing 1, and also improve the stability of the cable.

[0030] Furthermore, such as Figure 3 As shown, a filter plate 5 slides through the side wall of the air inlet pipe 6; the filter plate 5 and the air inlet pipe 6 are interference fit. During operation, the filter plate 5 can filter impurities and dust from the outside. The interference fit between the filter plate 5 and the air inlet pipe 6 can ensure the stability of the filter plate 5 installation. Furthermore, when the filter plate 5 needs to be replaced, it can be pulled directly. The disassembly and assembly process is quick and convenient, improving its practicality.

[0031] Furthermore, such as Figure 2 and Figure 6 As shown, the inner wall of the vent 7 is provided with a sliding groove 8; the bottom of the protective plate 3 is fixedly connected to an L-shaped sliding plate 38; the bottom of the L-shaped sliding plate 38 is slidably connected to the inner wall of the sliding groove 8; the top of the housing 1 is provided with a sealing groove 10; the bottom of the protective plate 3 is fixedly connected to a sealing frame 39; the sealing frame 39 contacts the inner wall of the sealing groove 10. When the protective plate 3 moves, it will simultaneously drive the L-shaped sliding plate 38 and the sealing frame 39 to move. The L-shaped sliding plate 38 will slide on the inner wall of the sliding groove 8 to ensure that the protective plate 3 can move stably up and down horizontally. The cooperation between the sealing frame 39 and the sealing groove 10 can ensure the sealing performance of the protective plate 3 when it is closed.

[0032] Furthermore, such as Figure 3As shown, a rectangular groove 61 is provided at the end of the air inlet pipe 6; a slider 37 is fixedly connected to the side wall of the second protective plate 32; the slider 37 is slidably connected to the inner wall of the rectangular groove 61; a fixing strip 36 is fixedly connected to the bottom end of the rectangular groove 61; a sealing strip 35 is fixedly connected to the bottom of the second protective plate 32; the sealing strip 35 contacts the inner wall of the fixing strip 36. When the second protective plate 32 moves, it will drive the slider 37 and the sealing strip 35 to move. The slider 37 will slide on the inner wall of the rectangular groove 61 to ensure the smooth movement of the second protective plate 32. The sealing strip 35 will detach from or insert into the inner wall of the fixing strip 36. With the cooperation of the sealing strip 35 and the fixing strip 36, the sealing performance of the second protective plate 32 when closed can be guaranteed.

[0033] Furthermore, such as Figure 2 and Figure 4 As shown, a fixing block 47 is fixedly connected to the bottom of the box 1; the outer wall of the sealing cylinder 4 is fixedly connected to the inner wall of the fixing block 47. During operation, the fixing block 47 ensures the stability of the sealing cylinder 4 during use, reduces the risk of shaking, and improves its practicality.

[0034] Furthermore, such as Figure 4 As shown, an exhaust pipe 46 is fixedly connected to the side wall of the T-shaped tube 45; the exhaust pipe 46 passes through and is fixed to the side wall at the bottom of the housing 1; a sealing cap 41 is inserted into the inner wall of the end of the exhaust pipe 46. During operation, when it is necessary to disassemble the wire in the middle of the wire release hole 9, the sealing cap 41 can be opened. At this time, the air in the inner wall of the annular airbag 44 will enter the T-shaped tube 45 and be discharged through the exhaust pipe 46, which improves the convenience of use. The outer wall of the sealing cap 41 that contacts the inner wall of the exhaust pipe 46 is made of rubber, and it will be squeezed and deformed when inserted into the inner wall of the exhaust pipe 46, which improves the stability of the sealing cap 41 to the exhaust pipe 46.

[0035] Working principle: When heat dissipation is required, the fan 33 can be started to blow out the hot air inside the housing 1, while the air from the outer wall will enter the housing 1 through the air inlet pipe 6, ensuring rapid heat dissipation inside the housing 1. When the fan 33 starts and drives the fan blades to rotate, the cylindrical tube 311 will also rotate. At this time, the sliding rod 314 will slide on the inner wall of the spiral groove 312 through the spiral amplitude. With the amplitude of the spiral groove 312, it will drive the sliding column 310 to rise and open until the sliding rod 314 moves to the inner wall of the annular groove 313. At this time, the cylindrical tube 311 continues to rotate, and the sliding rod 314 can only slide on the inner wall of the annular groove 313. It will not continue to rise or fall. This state is the state where the protective plate 3 is fully open. In addition, when the protective plate 3 moves open, the connecting plate 31 will drive the protective plate 32 to move, releasing the seal of the protective plate 32 on the air inlet pipe 6. This ensures that the housing 1 can dissipate heat smoothly. After heat dissipation is completed, the fan 33 can be stopped and started, causing the fan 33 to rotate in the opposite direction. When the sliding rod 314 passes through the connection between the spiral groove 312 and the annular groove 313, it will enter the interior of the spiral groove 312 by gravity and move downward along the amplitude of the spiral groove 312. The subsequent structural cooperation is the same as above. This allows the protective plate 3 and the protective plate 32 to close synchronously, ensuring that when ventilation and heat dissipation are not required, external moisture will not enter the interior of the housing 1, thus improving the service life of the electronic components inside the housing 1 that control the automatic start and stop of the engine.

[0036] When the cable is threaded through the feed hole 9, the lever 42 can be pushed and pulled repeatedly. The lever 42 will drive the piston block 49 to move against the inner wall of the sealing cylinder 4. In this way, outside air will enter the interior of the sealing cylinder 4 through the one-way valve 43 and the T-shaped tube 45 through the one-way valve 48. Then, it will enter the interior of the annular airbag 44, causing the annular airbag 44 to expand and compress the cable. This will fill the gap between the cable and the feed hole 9, improve the sealing effect of the housing 1, and also improve the stability of the cable. When it is necessary to disassemble the cable in the middle of the feed hole 9, the sealing cover 41 can be opened. At this time, the air inside the annular airbag 44 will enter the T-shaped tube 45 and be discharged through the exhaust pipe 46, which improves the convenience of use.

[0037] Meanwhile, the filter plate 5 can filter out impurities and dust from the outside. The filter plate 5 and the air inlet pipe 6 are interference fit, which can ensure the stability of the filter plate 5 installation. In addition, when the filter plate 5 needs to be replaced, it can be pulled directly. The disassembly and assembly process is quick and convenient, which improves its practicality.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
