Description

The invention relates to mechanics (valve and mechanical engineering), in particular to devices for draining fluids from the crankcase cavities of machines, and can be used in their maintenance and repair both in field and stationary conditions.

Drainage devices are widely used in the maintenance and repair of machines. A device is known, consisting of a container with a fixed tube rigidly attached to its upper part, a funnel with a movable tube telescopically interacting with a fixed tube (US Patent 1951489 A, (WHITNEY), 01/25/1930) [1].

The disadvantage of the known device is that it has a complex and expensive design. However, it does not provide the ability to use the container as a removable (replaceable) element.

The closest technical solution, chosen as a prototype, is a device for draining oil from the crankcase cavities of machines into canisters. It also consists of a funnel with a rigid base under it in the shape of a tube, an adapter with drain pipes vertically built into it, the number of which is more than one, oil canisters installed on the base, the number of which is equal to the number of drain pipes. In this case, the upper sections of the adapter tubes lie in the same horizontal plane with the upper edge of the adapter itself, and the lower sections of these tubes are made with the possibility of connecting sleeves to them for the simultaneous passage of oil into the canisters. The throughput of the hoses is greater than the throughput of the drain pipes, and the throughput of these pipes is greater than the throughput of the funnel mesh, the throughput of which exceeds the throughput of the crankcase drain hole. The canisters have the same capacity, and their total capacity is 15 ... 20% more than the volume of oil drained from the crankcase. This device includes a funnel with a mesh and a tube. (Decision to issue a patent of the Russian Federation on application No. 2017109512, F16N 31/00 (2006.01), 03/21/2017) [2].

The disadvantage of this device is that it is not well suited for intended use due to the low stability of the canisters in the vertical position, which makes it possible for them to overturn when they are accidentally exposed to force, and this leads to oil spillage.

The objective of the invention is to provide a drain device with the possibility of simultaneous drainage of oil from the crankcase of the machine into several canisters of small capacity.

The essence of the invention is as follows. The adapter is placed in the cavity of the tube for the funnel and is rigidly connected to a stand made in the form of a rod, to the side surface of which drain tubes are rigidly attached. In this case, the axis of rotation of the rod coincides with the axis of rotation of the tube for the funnel, the upper sections of the drain pipes lie in the same horizontal plane with the upper cut of the rod, its free end is made to form a thread onto which a nut is screwed and through which the rod is connected to a disk placed horizontally, and the nut has the ability to interact with its lower end surface with the upper end surface of the disc. To the disk, from the side of its lower end surface, supports are rigidly attached with the possibility of installing the device on the base in a vertical position. The canisters are installed horizontally on the base, and so that their necks are at the top and the handles are at the bottom. In this position, the total capacity of the canisters, taking into account the filling of oil in their cavity to the level passing through the lower point of the outer side surface of the neck, is 15 ... 20% more than the volume of liquid drained from the crankcase. Taken together, this made it possible to create a drain device with the ability to simultaneously drain oil from the crankcase of the machine into several canisters of small capacity. At the same time, the stability of the canisters on the base is ensured, since they are placed horizontally, and the level of the collected oil in them is lower than the location of the necks, which reduces the possibility of canisters tipping over when accidentally applied to them, and this leads to a decrease in the risk of oil spillage.

FIG. 1, 2, 3, 4 and 5 show a device for collecting oil in cans during maintenance of machines, in particular in FIG. 1 shows its general view (front view) with local sections, FIG. 2 - section A-A, in Fig. 3 - view B, Fig. 4 and 5 show sections B-B and G-D.

The device consists of a funnel 3 with a tube 5 for it, an adapter 14 with vertically integrated drain tubes 7, the number of which is more than one (for example, three), 15 canisters for oil of the same capacity, installed on the base 13, the number of which is equal to the number of drain tubes 7. The adapter 14 is placed in the cavity of the tube 5 under the funnel 3 and is rigidly connected to the post 6, made in the form of a rod, to the side surface of which the drain pipes are rigidly attached 7. In this case, the axis of rotation of the rod of the post 6 coincides with the axis of rotation of the tube 5 under the funnel 3 The upper sections of the drain tubes 7 lie in the same horizontal plane with the upper sections of the rod of the rack 6 and the adapter itself 14. The lower sections of these tubes 7 are made with the possibility of being connected to them by means of nipples 8 of the sleeves 9 for the simultaneous passage of oil into the cans 15. For this, the free ends sleeves 9 are lowered into the cavity of canisters 15 through their necks. The free end of the rod of the rack 5 is made with the formation of a thread onto which the nut 10 is screwed and by means of which the rod is connected to the disk 11 placed horizontally, and the nut 10 has the ability to interact with its lower end surface with the upper end surface of the disk 11. To the disk 11, from the side its lower end surface, supports 12 are rigidly connected with the possibility of installing the device on the base 13 in a vertical position. The canisters 15 are mounted on the base 13 horizontally, and in such a way that their necks are at the top and the handles are at the bottom (handles are not shown). In this position, the total capacity of the canisters is 15, taking into account the filling of oil in their cavity to the level passing through the lower point of the outer lateral surface of the neck, by 15 ... 20% more than the volume of liquid drained from the crankcase. The throughput of the sleeves 9 is greater than the throughput of the drain pipes 7, and the throughput of these pipes 7 is greater than the throughput of the mesh 4 of the funnel 3, the throughput of which exceeds the throughput of the crankcase drain hole (not shown).

The principle of operation of the device is as follows. Install the device on the base 13 under the crankcase 1, for example, the engine - in the area of the drain plug 2 (Fig. 1). Loosen the nut 10 and adjust the position of the funnel 3 in height by screwing or unscrewing the rod of the rack 6 into the disk 11. Then the nut 10 is tightened, pressing it to the disk 10. The free ends of the sleeves 9 are lowered into the cavities of the canisters 15, installed horizontally on the base 13. Then unscrew the plug 2 and drain the oil from the crankcase L into the canisters 15. With sufficient throughput of the structural elements of the device, the oil through the funnel 3 with the mesh 4, tubes 7 and sleeves 9 freely drains into canisters 15, displacing air from their cavities into the atmosphere through the gaps in necks. Since the canisters 9 have the same capacity, and their total capacity to the level of the necks is 15 ... 20% more than the volume of oil drained from the crankcase of the machine, then the overflow of canisters 15, taking into account the possible uneven distribution of oil along the sleeves 9, is not observed. At the end of the process of draining the oil, the sleeves 9 are removed from the canisters 15, and the device is removed from under the crankcase 1.

Thus, the proposed drainage device with the ability to simultaneously drain oil from the crankcase of the machine into several canisters of small capacity. At the same time, the stability of the canisters on the base is ensured, since they are placed horizontally, and the level of the collected oil in them is lower than the location of the necks, which reduces the possibility of canisters tipping over when accidentally applied to them, and this leads to a decrease in the risk of oil spillage.
