Description

Technical Field

[0001] The utility model belongs to the field of oil engines and relates to a data acquisition device for DC oil engines. Background Art

[0002] The data acquisition device for oil engines can be applied to various types of engines and machinery. It can help operators monitor the normal operation of oil engines, detect potential faults, and improve maintenance efficiency. Generally speaking, such collectors are suitable for DC power supplies, such as 12V or 24V power supplies, and can be applied to various gasoline and diesel engines, as well as some other railway, water transportation, and aviation equipment.

[0003] Currently, the data acquisition device for oil engines is not only used indoors but also commonly used outdoors. When used outdoors, the connectors of the data acquisition device for oil engines are exposed to the air for a long time during idle periods, which can cause dust and oil stains to enter, easily lead to poor electrical contact in the circuit, cause local heating and short circuits, and even trigger fires. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a data acquisition device for DC oil engines, which solves the problem that when the data acquisition device for oil engines is used outdoors, the connectors of the data acquisition device for oil engines are exposed to the air for a long time during idle periods, resulting in dust and oil stains entering.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The data acquisition device for DC oil engines includes a collector main body. A circular male connector is installed on the outer wall of the collector main body. A protective shell is installed outside the male connector. The protective shell is a cylindrical tube with both ends completely open. The male connector is located inside the protective shell, and one end of the protective shell is fixedly connected to the outer wall of the collector main body. The other end of the protective shell is detachably connected with a sealing cover for blocking the port of the protective shell.

[0007] The sealing cover and the protective shell are fixedly connected through a telescopic rod. The telescopic direction of the telescopic rod is parallel to the axial direction of the protective shell. An ear plate is installed at one end of the telescopic rod. The other end of the telescopic rod is fixedly connected to the outer wall of the sealing cover. The ear plate is installed on a horizontally placed fixed shaft. The fixed shaft is fixedly connected to the outer wall of the protective shell. The ear plate is rotatably connected to the fixed shaft. The extension line of the central axis of the fixed shaft and the extension line of the central axis of the protective shell form a 90° angle. The ear plate rotates around the fixed shaft as the rotation center. When the telescopic rod is shortened to the shortest, the sealing cover blocks the corresponding port of the protective shell.

[0008] The collector body in the present utility model is a prior art, such as an existing mobile diesel generator data collector; on the basis of the existing mobile diesel generator data collector, the present utility model is equipped with a protection device capable of dust-proofing the male connector, solving the problem that when the oil engine data collection device is used outdoors, the connector of the oil engine data collection device is exposed to the air for a long time during idle time, and dust and oil stains will enter.

[0009] In the present utility model, the protection shell wraps the male connector inside. One end of the protection shell is fixedly connected to the outer wall of the collector body, and the outer wall of the collector body seals the port of this end of the protection shell. The other end of the protection shell is hermetically connected through a detachable sealing cover. The sealing cover and the outer wall of the collector body form a relatively sealed cavity inside the protection shell. The male connector is located in this sealed cavity to achieve the purpose of being protected, and the male connector can avoid entering a large amount of dust by not being exposed to the environment for a long time.

[0010] When the present utility model needs to insert a female connector into the male connector, the sealing cover needs to be opened. However, after the sealing cover is opened, for the convenience of storage, the present utility model uses a telescopic rod, an ear plate, and a fixed shaft as the connection structure between the sealing cover and the protection shell; when the sealing cover is hermetically installed on the protection shell, the telescopic rod rotates around the fixed shaft through the ear plate until the telescopic rod is horizontally placed. At this time, the axial direction of the telescopic rod is parallel to the central axis of the protection shell. Subsequently, the telescopic rod is shortened to the shortest. During the shortening process of the telescopic rod, the sealing cover is driven to move towards the port of the protection shell. When the telescopic rod is shortened to the shortest, the sealing cover is tightly connected to the port of the protection shell, sealing the port of the protection shell, and a sealed cavity is formed inside the protection shell, and the male connector is protected inside the protection shell; when it is necessary to open the sealing cover and insert the female connector into the male connector, the telescopic rod first remains in a horizontal state, and then the telescopic rod is elongated along the axial direction of the protection shell. During the elongation process of the telescopic rod, the sealing cover is pushed to the side away from the protection shell. When the sealing cover completely disengages from the protection shell, the telescopic rod is rotated through the ear plate, and the telescopic rod rotates upward so that the sealing cover reaches above the protection shell. At this time, the port of the protection shell is completely exposed, and the female connector can pass through the corresponding port on one side of the protection shell and enter the inside of the protection shell and be plugged into the male connector; during the whole process, it is not necessary to completely disassemble the sealing cover from the protection shell, avoiding the situation of the sealing cover being lost when the sealing cover is opened.

[0011] A locking structure of the telescopic rod is provided on the telescopic rod in the present utility model. The locking structure can be a chuck, a clamp, a bolt, etc. The locking structures of the telescopic rod such as a chuck, a clamp, a bolt, etc. are all prior arts, and the telescopic rod matching with the above structure is also a prior art.

[0012] Further, the telescopic rod includes a sleeve and a sliding rod with coincident central axes. A part of the sliding rod is located inside the sleeve, and the sliding rod is slidably connected to the sleeve. The sleeve is a cylindrical tube with completely open ends at both ends. One end of the sleeve is fixedly connected to the ear plate, and a coaxial hollow chuck is installed at the other end of the sleeve. The sliding rod passes through the middle channel of the hollow chuck along its axial direction. One end of the sliding rod is located inside the sleeve, and the other end of the sliding rod is fixedly connected to the outer wall of the sealing cover. The sleeve locks the sliding rod through the hollow chuck.

[0013] In the present utility model, the sleeve and the sliding rod are used as the main parts of the telescopic rod. The sleeve is fixed, and the sliding rod slides along the axial direction of the sleeve to realize the telescoping of the telescopic rod. After the sliding rod slides to the target position, the sliding rod is fixed by the hollow chuck, thereby realizing the locking of the sliding rod, and further realizing the locking of the entire telescopic rod.

[0014] Further, one end of the protective shell is fixedly connected to the outer wall of the collector body. At the port of the other end of the protective shell, a circular flexible separator pad matching the shape of the port of the protective shell is installed. The flexible separator pad is composed of multiple independent and circumferentially evenly distributed sector-shaped elastic pads. All the sector-shaped flexible pads are sequentially connected to form a complete circular structure. The arc-shaped walls of all the sector-shaped flexible pads are sequentially connected to form a complete circumferential wall. The circumferential wall is fixedly connected to the port wall of the protective shell. When the female connector matching the male connector is inserted into the male connector, all the sector-shaped elastic pads are deformed and bent to form a channel for the female connector to pass through.

[0015] In the present utility model, a flexible separator pad is installed at the port where the male and female connectors of the protective shell are inserted. The flexible separator pad is composed of multiple independent and circumferentially evenly distributed sector-shaped elastic pads. After removing the sealing cover, the female connector is directly inserted into the protective shell from the center of the flexible separator pad. During the movement of the female connector, the sector-shaped elastic pads will be squeezed and deformed. After the tips of all the sector-shaped elastic pads are bent and deformed, a channel for the female connector to move through will be formed in the middle of all the sector-shaped elastic pads. When the female connector is pulled out, all the sector-shaped elastic pads will return to their original state due to elastic deformation, and all the sector-shaped elastic pads will form a complete circular pad again. The complete circular pad plays a certain protective role for the port, and even if the sealing cover is forgotten to be installed, it also plays a certain dust-proof role for the male connector. Therefore, the sealing cover and the flexible separator pad in the present utility model play a double-layer protection role for the male connector.

[0016] Further, a rubber pad is installed on the inner bottom surface of the sealing cover. When the sealing cover seals the corresponding port of the protective shell, the port of the protective shell is in close contact with the rubber pad.

[0017] The rubber pad plays a role in strengthening the seal, which is the same as that of the existing sealing pad.

[0018] Further, the male connector is a multi-pin core connector.

[0019] Furthermore, the hollow chuck is a hollow three-jaw chuck.

[0020] Furthermore, the sealing cover and the protective shell are fixedly connected by two synchronously moving telescopic rods, and the two telescopic rods are respectively located on both sides of the sealing cover.

[0021] The two telescopic rods play a role in maintaining balance.

[0022] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0023] 1. On the basis of the existing mobile oil engine data collector, the present utility model is equipped with a protective device capable of dust-proofing the male connector, solving the problem that when the oil engine data collection device is used outdoors, the connector of the oil engine data collection device is exposed to the air for a long time during idle time, and dust and oil stains will enter.

[0024] 2. The present utility model installs a flexible spacer on the port where the male and female connectors of the protective shell are inserted, and the sealing cover and the flexible spacer play a double-layer protection role for the male connector. BRIEF DESCRIPTION OF THE DRAWINGS
