Description

Technical Field

[0001] This utility model relates to the technical field of oil replenishment devices, specifically an oil replenishment device for a Roots vacuum pump. Background Technology

[0002] A Roots vacuum pump is a mechanical vacuum pump commonly used in high vacuum and ultra-high vacuum systems. It consists of a pair of meshing but non-contacting impellers, often referred to as "Roots impellers" or "Roots gears." This design allows Roots pumps to operate at low pressures and produce high pumping speeds, making them highly effective across a range from atmospheric pressure to high vacuum.

[0003] For example, application number CN202420810588.6 relates to the field of oil replenishment devices. To address the shortcomings of existing technologies that require repeated manual replenishment of lubricating oil in the oil cup, resulting in low work efficiency, this invention proposes a Roots vacuum pump oil replenishment device. The device includes an equipment box, with an oil storage tank fixedly installed inside. An oil pipe is fixedly installed on one side of the top of the oil storage tank, and a pipe joint is provided on the surface of the oil pipe. A vacuum pump body is fixedly installed on the top of the equipment box. This invention, through the arrangement of the oil pipe, oil storage tank, piston block, and piston rod, pushes a certain amount of lubricating oil through the oil pipe into the gearbox of the vacuum pump body. Then, the piston block resets, carrying excess lubricating oil back to the oil storage tank. By setting the piston block's movement to increase by an equal amount each time, it can automatically replenish the gearbox in the vacuum pump body with equal amounts of lubricating oil multiple times, eliminating the need for repeated manual delivery of equal amounts of lubricating oil, reducing the workload of workers, and improving the efficiency of equipment oil replenishment.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem of the need for manual replenishment of lubricating oil cups multiple times, and the need to control the amount added during the replenishment process, which increases the workload and reduces work efficiency, the continuous friction between the cleaning plate and the heat dissipation holes during prolonged use will cause the cleaning plate to gradually wear down. This wear will reduce the cleaning effect of the cleaning plate, making it unable to effectively remove dust and dirt from the heat dissipation holes, thereby affecting the heat dissipation performance of the system.

This solves the problem that when cleaning the heat dissipation holes for a long time, the continuous friction between the cleaning plate and the heat dissipation holes will cause the cleaning plate to gradually wear down. This wear will reduce the cleaning effect of the cleaning plate, making it unable to effectively remove dust and dirt from the heat dissipation holes, thereby affecting the heat dissipation performance of the system.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Roots vacuum pump oil replenishment device, comprising an equipment box, a protective cover, heat dissipation holes, a cleaning plate, a maintenance door, and a movable rod. The protective cover is fixedly connected to the top of the equipment box. The heat dissipation holes are all located on the right side of the equipment box and the right side of the protective cover. The cleaning plate is movably connected to the right side of the heat dissipation holes. The maintenance door is movably connected to the front of the equipment box. The movable rod is movably connected to the right side of the equipment box. A fixing seat is fixedly connected to the right end of the movable rod. A first groove is provided on the back of the fixing seat. A connector is fixedly connected to the front of the cleaning plate. The connector is movably connected to the first groove. A positioning component is provided inside the first groove. A cleaning component is provided on the left side of the surface of the movable rod.

[0007] In a preferred embodiment of the present invention, the positioning component includes a second groove, a first spring, and a positioning member. The second groove is formed on the right side of the positioning member, and the positioning member is movably connected inside the second groove. The first spring is fixedly connected to the right side of the positioning member, and the other end of the first spring is fixedly connected to the right side of the first groove.

[0008] In a preferred embodiment of this invention, the cleaning assembly includes a fixing plate, a second spring, and a cleaning component. The fixing plate is fixedly connected to the left side of the surface of the movable rod, and the second spring is fixedly connected to the right side of the fixing plate. Several second springs are provided and are distributed in a rectangular, equidistant manner. The cleaning component is fixedly connected to the other end of the second spring and is movably connected to the heat dissipation hole.

[0009] As a preferred embodiment of this utility model, a collection box is provided on the right side of the equipment box, and a locking block is fixedly connected to both sides of the left side of the collection box. A slot is provided on both sides of the right side of the equipment box, and the locking block engages with the slot.

[0010] As a preferred embodiment of the present invention, a first pin is fixedly connected to the right side of the positioning member, the right end of the first pin extends through to the right side of the fixing seat, and the first spring is sleeved on the surface of the first pin.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a fixed base, a first groove, and a connector, allows the cleaning plate to move along with the connector, and then the connector is inserted into the first groove of the fixed base. This allows the connector to move the cleaning plate into the first groove, facilitating installation and disassembly. It solves the problem that when cleaning the heat dissipation holes for a long time, the continuous friction between the cleaning plate and the heat dissipation holes will cause the cleaning plate to gradually wear down. This wear will reduce the cleaning effect of the cleaning plate, making it unable to effectively remove dust and dirt from the heat dissipation holes, thus affecting the heat dissipation performance of the system. This utility model has the advantage of easy installation and disassembly of the cleaning plate.

[0015] 2. This utility model, by setting a positioning component, allows the connecting piece to contact the positioning component inside the first groove when the cleaning plate drives the connecting piece to insert into the first groove. The positioning component then compresses the first spring, causing the connecting piece to insert deep into the first groove, with the left side of the positioning component contacting the right side of the connecting piece. Simultaneously, when the second groove is opposite the positioning component, the first spring releases pressure, causing the positioning component to move and insert into the first groove. This allows the positioning component and the second groove to work together to position the connecting piece. Furthermore, by setting a cleaning component, when the equipment box drive source rotates the movable rod, the movable rod rotates the fixed plate, which in turn rotates the second spring. The second spring then rotates the cleaning component, causing it to connect movably with the heat dissipation holes. This allows the cleaning component to clean the dust inside the heat dissipation holes. Finally, when the fixed plate rotates the second spring, it causes the positioning component to reset and insert into the next row of heat dissipation holes, preventing blockage.

[0016] 3. This utility model, by setting up a collection box, a card block, and a card slot, allows the collection box to drive the card block to move, and then the card block to insert into the inside of the card slot. After that, the collection box cleans the dust off the cleaning plate and collects it. Thus, the card block and the card slot work together to facilitate the disassembly and installation of the collection box. Furthermore, by setting up a first pin, the safety and stability of the first spring are increased, preventing the first spring from twisting and being damaged during the compression and contraction process, thereby extending the service life of the first spring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 3 As shown, the present invention provides a Roots vacuum pump oil replenishment device, including an equipment box 1, a protective cover 2, heat dissipation holes 3, a cleaning plate 4, a maintenance door 5, and a movable rod 6. The protective cover 2 is fixedly connected to the top of the equipment box 1. The heat dissipation holes 3 are all opened on the right side of the equipment box 1 and the right side of the protective cover 2. The cleaning plate 4 is movably connected to the right side of the heat dissipation holes 3. The maintenance door 5 is movably connected to the front of the equipment box 1. The movable rod 6 is movably connected to the right side of the equipment box 1. A fixing seat 7 is fixedly connected to the right end of the movable rod 6. A first groove 8 is opened on the back of the fixing seat 7. A connector 9 is fixedly connected to the front of the cleaning plate 4. The connector 9 is movably connected to the first groove 8. A positioning component 10 is provided inside the first groove 8. A cleaning component 11 is provided on the left side of the surface of the movable rod 6.

[0024] refer to Figure 2 The positioning component 10 includes a second groove 101, a first spring 102, and a positioning member 103. The second groove 101 is formed on the right side of the positioning member 103. The positioning member 103 is movably connected inside the second groove 101. The first spring 102 is fixedly connected to the right side of the positioning member 103. The other end of the first spring 102 is fixedly connected to the right side inside the first groove 103.

[0025] As a technical optimization of this utility model, by setting a positioning component 10, when the cleaning plate 4 drives the connector 9 to be inserted into the first groove 8, the connector 9 comes into contact with the positioning component 103 inside the first groove 8. Then, the positioning component 103 drives the first spring 102 to compress and shrink, and then the connector 9 is inserted deep into the first groove 8, so that the left side of the positioning component 103 contacts the right side of the connector 9. At the same time, when the second groove 101 is opposite to the positioning component 103, the first spring 102 releases pressure and drives the positioning component 103 to move and insert into the first groove 8, so that the positioning component 103 and the second groove 101 work together to position the connector 9.

[0026] refer to Figure 3 The cleaning assembly 11 includes a fixed plate 111, a second spring 112, and a cleaning component 113. The fixed plate 111 is fixedly connected to the left side of the surface of the movable rod 6. The second spring 112 is fixedly connected to the right side of the fixed plate 111. Several second springs 112 are provided and are distributed in a rectangular shape at equal intervals. The cleaning component 113 is fixedly connected to the other end of the second spring 112 and is movably connected to the heat dissipation hole 3.

[0027] As a technical optimization of this utility model, by setting up a cleaning component 11, when the drive source of the equipment box 1 drives the movable rod 6 to rotate, the movable rod 6 drives the fixed plate 111 to rotate, and then the fixed plate 111 drives the second spring 112 to rotate. After that, the second spring 112 drives the cleaning component 113 to rotate, and at the same time, the cleaning component 113 is movably connected to the heat dissipation hole 3, so that the cleaning component 113 cleans the dust inside the heat dissipation hole 3. Thus, when the fixed plate 111 drives the second spring 112 to rotate, it drives the positioning component 103 to reset and insert into the next row of heat dissipation hole 3 to prevent the hole from being blocked.

[0028] refer to Figure 2 A collection box 12 is provided on the right side of the equipment box 1. Both sides of the left side of the collection box 12 are fixedly connected with a card block 13. Both sides of the right side of the equipment box 1 are provided with a card slot 14, and the card block 13 and the card slot 14 are engaged.

[0029] As a technical optimization of this utility model, by setting up a collection box 12, a card block 13 and a card slot 14, the collection box 12 drives the card block 13 to move, and then the card block 13 is inserted into the inside of the card slot 14. After that, the collection box 12 cleans the dust off the cleaning plate 4 and collects it, so that the card block 13 and the card slot 14 work together to facilitate the disassembly and installation of the collection box 12.

[0030] refer to Figure 3The right side of the positioning component 103 is fixedly connected to a first pin 15, the right end of the first pin 15 extends through to the right side of the fixed seat 7, and the first spring 102 is sleeved on the surface of the first pin 15.

[0031] As a technical optimization of this utility model, by setting the first pin 15, the safety and stability of the first spring 102 are increased, and the first spring 102 is prevented from twisting and being damaged during the compression and contraction process, thereby extending the service life of the first spring 102.

[0032] refer to Figure 3 A pull rod 16 is fixedly connected to the right end of the first pin 15. The surface of the pull rod 16 is provided with anti-slip texture 17, which is provided in several rectangular and equally spaced patterns.

[0033] As a technical optimization of this utility model, by setting a pull rod 16 and anti-slip texture 17, when it is necessary to disassemble the connecting piece 9, by gripping the pull rod 16, the pull rod 16 drives the first pin 15 to move, then the first pin 15 drives the positioning piece 103 to move, then the positioning piece 103 drives the first spring 102 to compress and contract, and at the same time, the positioning piece 103 disengages from the first groove 8. Finally, the cleaning plate 4 drives the connecting plate to be pulled out from the inside of the first groove 8, so that the pull rod 16 drives the positioning piece 103 to move and complete the removal and disassembly of the cleaning plate 4. At the same time, when gripping the handle, the friction generated by contacting the anti-slip texture 17 is increased to prevent slippage when contacting the pull rod 16.

[0034] refer to Figure 4 The left side of the cleaning component 113 is fixedly connected to a second pin 18, the left end of the second pin 18 extends through to the left side of the fixing plate 111, and the second spring 112 is sleeved on the surface of the second pin 18.

[0035] As a technical optimization of this utility model, by setting a second pin 18, the safety and stability of the second spring 112 are increased, preventing the second spring 112 from twisting and being damaged during the compression and contraction process, thereby extending the service life of the second spring 112.

[0036] The working principle and usage process of this utility model are as follows: During use, when the drive source of the equipment box 1 drives the movable rod 6 to rotate, the movable rod 6 drives the fixed plate 111 to rotate. Then, the fixed plate 111 drives the second spring 112 to rotate. Subsequently, the second spring 112 drives the cleaning component 113 to rotate, simultaneously causing the cleaning component 113 to movably connect with the heat dissipation hole 3. This allows the cleaning component 113 to clean the dust inside the heat dissipation hole 3. As the fixed plate 111 drives the second spring 112 to rotate, it causes the positioning component 103 to reset and insert into the next row of heat dissipation hole 3 to prevent blockage. Simultaneously, when the cleaning plate 4 drives the connecting component 9 to insert into the first groove 8, the connecting component... The connector 9 contacts the positioning member 103 inside the first groove 8, and then the positioning member 103 drives the first spring 102 to compress and shrink. Then, the connector 9 is inserted deep inside the first groove 8, so that the left side of the positioning member 103 contacts the right side of the connector 9. At the same time, when the second groove 101 is opposite to the positioning member 103, the first spring 102 releases pressure and drives the positioning member 103 to move and insert into the first groove 8. Thus, the positioning member 103 and the second groove 101 work together to install and position the connector 9. Then, the movable rod 6 drives the cleaning plate 4 to rotate through the fixed seat 7 to clean the heat dissipation hole 3. This gives the cleaning plate 4 the advantage of installation and disassembly.

[0037] In summary, this Roots vacuum pump oil replenishment device, through the setting of a fixed base 7, a first groove 8, and a connecting member 9, allows the cleaning plate 4 to move along with the connecting member 9, and then the connecting member 9 is inserted into the first groove 8 opened in the fixed base 7. This allows the connecting member 9 to move the cleaning plate 4 into the first groove 8, facilitating its installation and disassembly. This solves the problem that when cleaning the heat dissipation holes for a long time, the continuous friction between the cleaning plate and the heat dissipation holes will cause the cleaning plate to gradually wear down. This wear will reduce the cleaning effect of the cleaning plate, making it unable to effectively remove dust and dirt from the heat dissipation holes, thus affecting the heat dissipation performance of the system.
