Description

Technical Field

[0001] This utility model relates to the field of refueling device technology, specifically to an online refueling device. Background Technology

[0002] Online refueling devices are widely needed and used in thin oil lubrication equipment, especially in equipment such as speed reducers, hydraulic stations, and thin oil stations where regular oil replenishment is required.

[0003] Currently, the most commonly used thin oil refueling devices are mainly as follows: Figure 1 The funnel refueling device shown is used by removing the vent cap of the equipment and connecting the funnel to the equipment via threads or flanges to replenish oil.

[0004] While existing funnel-type refueling devices are convenient and easy to operate in practice, and readily accessible, they suffer from the following drawbacks due to the lack of synchronized venting:

[0005] 1. Due to the positive pressure inside the oil tank or transmission box, when using a funnel refueling device to replenish oil, the positive pressure inside the tank can easily exert lateral pressure on the sealing positions of the tank, resulting in a decrease in sealing performance and a potential risk of oil leakage.

[0006] 2. When the pressure inside the tank accumulates to a certain value, it can easily backflush the oil in the funnel, causing oil to splash and posing certain hidden dangers and impacts to on-site oil replenishment operations and the on-site environment.

[0007] In addition, the existing funnel refueling device is not equipped with a filter, which does not effectively guarantee the cleanliness of the environment and the cleanliness of the oil during the refueling process, which can easily lead to oil contamination and performance degradation. Utility Model Content

[0012] The oil replenishment pipe is installed in the oil replenishment pipe mounting hole. One end of the oil replenishment pipe is used to communicate with the inside of the oil tank or transmission box, and the other end of the oil replenishment pipe is connected to the outside. The filter assembly is set in the oil replenishment pipe and is used to filter the replenished oil.

[0013] As a further improvement of this utility model, the connecting part is a connecting thread or connecting flange provided at the bottom of the oil replenishing funnel, used to connect with the installation interface of the vent cap on the oil tank or transmission box.

[0014] As a further improvement of this utility model, the one-way valve assembly is a one-way float ball, which is movably disposed inside the exhaust pipe.

[0015] As a further improvement of this utility model, it also includes an exhaust cap, which is provided at the end of the exhaust pipe away from the oil tank or transmission box, that is, the exhaust cap is provided at the outer end of the exhaust pipe, and the exhaust cap has a lateral exhaust hole.

[0016] As a further improvement of this utility model, the filter component is an oil replenishment filter screen, which is fixedly or detachably installed inside the oil replenishment pipe.

[0017] As a further improvement of this utility model, the length of the oil replenishment pipe extending into the oil tank or transmission box is greater than the length of the exhaust pipe extending into the oil tank or transmission box, and the bottom of the oil replenishment pipe is provided with a tapered inclination angle facing away from the exhaust pipe.

[0018] As a further improvement of this utility model, it also includes a guide plate, which is fixedly disposed inside the oil replenishment funnel, and one end of the guide plate extends to the inlet of the oil replenishment pipe.

[0019] As a further improvement of this utility model, the oil replenishment funnel has a conical structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention, by setting up an exhaust pipe and a one-way valve assembly, can achieve pressure balance inside and outside the oil tank or transmission box, avoid the influence of positive pressure inside the box on the sealing position, reduce the risk of oil leakage, and also prevent oil splashing caused by pressure backflow, thus improving the safety of online oil replenishment.

[0022] The one-way valve assembly of this invention ensures that gas inside the chamber is discharged while effectively preventing external gas and dust from entering the chamber, thus ensuring a clean environment inside the chamber.

[0023] This invention, by installing a filter component inside the oil replenishment pipe, can filter the replenished oil, ensuring the cleanliness of the oil and avoiding oil contamination and performance degradation.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings:

[0032] like Figure 2 As shown, this utility model provides an online cleaning and refueling device, including an oil replenishment funnel 1, an exhaust pipe 3, a one-way float 4, an oil replenishment pipe 8, an oil replenishment filter 9, and a guide plate 10.

[0033] The oil replenishment funnel 1 of this utility model has a conical structure with a connecting thread 2 at its bottom. This thread 2 allows it to connect to the interface on the oil tank or transmission box after the vent cap has been removed, providing a stable connection and good sealing performance. It can also be extended to a flange connection according to actual needs. Oil can be replenished into the oil tank or transmission box through the oil replenishment funnel 1. Figure 3As shown, the oil replenishment funnel 1 has an exhaust pipe mounting hole 1.1 and an oil replenishment pipe mounting hole 1.2, which are used to install the exhaust pipe 3 and the oil replenishment pipe 8, respectively.

[0034] The exhaust pipe 3 of this invention is vertically installed in the exhaust pipe mounting hole 1.1. One end of the exhaust pipe 3 is connected to the inside of the oil tank or transmission box, and the other end extends to the outside of the oil replenishment funnel 1. A one-way float 4 is installed inside the section of the exhaust pipe 3 outside the oil replenishment funnel 1. This one-way float 4 constitutes a one-way valve assembly, allowing the positive pressure gas inside the oil tank or transmission box to be discharged outwards in one direction, while preventing external gas, dust, etc., from entering the box. An exhaust cap 5 is installed on the end of the exhaust pipe 3 away from the oil tank or transmission box. A side exhaust hole 6 is provided on the exhaust cap 5 to ensure the orderly discharge of gas inside the box, avoiding the impact of vertical exhaust on the oil replenishment process. It also prevents dust from falling in and facilitates the condensation and backflow of oil and gas, avoiding environmental impact. An oil tank vent 7 is provided on the oil tank or transmission box at the position corresponding to the exhaust pipe 3. This oil tank vent 7 is a side-opening design, which avoids high oil and gas content in the vertical airflow and ensures the smooth discharge of the upper positive pressure gas.

[0035] The oil replenishment pipe 8 of this invention is installed inside the oil replenishment pipe mounting hole 1.2. One end of the oil replenishment pipe 8 extends into the oil tank or transmission box, with a length greater than that of the exhaust pipe 3 extending into the box, to effectively avoid positive pressure airflow and ensure smooth oil replenishment. The other end of the oil replenishment pipe 8 is connected to the outside. The bottom of the oil replenishment pipe 8 is designed with a tapered inclination angle and faces away from the exhaust pipe 3, further ensuring safe oil replenishment. An oil replenishment filter 9 is fixedly or detachably installed inside the oil replenishment pipe 8. The oil replenishment filter 9 constitutes a filtration assembly, which can further filter the replenished oil to ensure oil cleanliness and prevent accidental contaminants from entering the box.

[0036] The guide plate 10 of this utility model is welded inside the oil replenishment funnel 1, with one end extending to the inlet of the oil replenishment pipe 8, which can ensure that the oil flows into the oil replenishment pipe 8 in a conical manner; the exhaust pipe 3 can pass through the oil replenishment pipe 8 to ensure the sealing between the oil replenishment pipe 8 and the exhaust pipe 3, and to ensure the smooth execution of the oil replenishment process.

[0037] The working process of this utility model is as follows:

[0038] During online oil replenishment, this device is installed on the oil tank or transmission box via the connecting thread 2 at the interface after removing the vent cap. Oil is poured into the oil replenishment funnel 1, and guided by the guide plate 10, it enters the oil replenishment pipe 8. After being filtered by the oil replenishment filter screen 9, the oil enters the oil tank or transmission box through the oil replenishment pipe 8. During the oil replenishment process, the positive pressure gas inside the oil tank or transmission box enters the exhaust pipe 3 through the oil tank vent 7, pushing open the one-way float 4 and exiting through the side exhaust port 6 on the exhaust cap 5, achieving pressure balance inside and outside the box. When the pressure inside the box is balanced with the outside or after oil replenishment is completed, the one-way float 4 falls back, sealing the exhaust pipe 3 to prevent external dust, moisture, etc., from entering the box.

[0039] The advantages of this utility model are:

[0040] This invention, by setting up an exhaust pipe and a one-way valve assembly, can achieve pressure balance between the inside and outside (cavity and external environment) of the oil tank or transmission box during oil replenishment, avoiding the influence of positive pressure inside the box on the sealing position and reducing the risk of oil leakage; at the same time, it also prevents oil splashing caused by pressure backflow, improving the safety of online oil replenishment.

[0041] The one-way valve assembly of this invention ensures that gas inside the chamber is discharged while effectively preventing external gas and dust from entering the chamber, thus ensuring a clean environment inside the chamber.

[0042] This invention, by installing a filter component inside the oil replenishment pipe, can filter the replenished oil, ensuring the cleanliness of the oil and avoiding oil contamination and performance degradation.

[0043] This utility model has a reasonable structural design and is easy to operate, which can effectively improve the efficiency of online oil replenishment and is suitable for oil replenishment under various working conditions.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
