Description

Technical Field

[0001] The utility model relates to the technical field of dust prevention of sampling ports, in particular to a dust prevention device for a fuel tank sampling tube. Background Art

[0002] There are two types of dust prevention measures at the sampling tube mouth of the power plant oil tank. One is to plug a rubber sealing plug at the inner hole of the sampling outlet, and the other is to install a rubber tube at the sampling tube mouth and fix it with a clip or wrap it with plastic paper. However, both methods cannot guarantee the cleanliness of the sampling tube, and are also prone to leakage of residual oil samples in the sampling tube and the risk of the plug falling off. In similar sampling fields, in the prior art, screw-connected covers are also used for sealing, such as the patent with publication number CN217483944U, which discloses the use of sealing sleeves, sealing covers, and sealing strips; however, it is not convenient for repeated use, and there is a possibility of accumulation of residual oil and oil residues combined with dust at the sealing place, which is not convenient for cleaning and has a limited service life.

[0003] Based on the above description, there is an urgent need for a dust-proof device for a fuel tank sampling tube that is not easy to accumulate dust and has a long service life. Utility Model Content

[0011] Preferably, a sealing gasket is provided at the top of the elastic groove; the sealing gasket abuts against the oil outlet of the sampling tube.

[0012] Preferably, a hemispherical protrusion is provided at one end of the elastic groove close to the sealing gasket; the hemispherical protrusion extends toward the oil outlet of the sampling tube.

[0013] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0014] The utility model preliminarily sleeves an umbrella-shaped cover body on a sampling tube, then sleeves a support plate and screws it on the sampling tube to support the umbrella-shaped cover body, and further connects a sealing sleeve to an end of the support plate away from the bulk cover body through a connecting piece, thereby ensuring that the oil outlet end of the sampling tube is sealed in the inner cavity of the sealing sleeve; wherein, the use of the umbrella-shaped cover body is convenient for staff to temporarily knock, vibrate and shake off dust, thereby reducing the number of times of disassembly and cleaning; in addition, the umbrella-shaped cover body, the support plate and the sealing sleeve are all detachably screwed, thereby facilitating disassembly, cleaning and repeated use, and facilitating replacement of the sealing gasket in the sealing sleeve.

[0019] Example 1

[0020] See also Figure 1 to Figure 2 The utility model provides the following technical solutions: a dustproof device for a fuel tank sampling tube, which is suitable for sealing and dustproofing the fuel tank sampling tube.

[0021] Specifically, Figure 1 and Figure 2As shown, a dustproof device for a fuel tank sampling tube comprises a sampling tube 1 and a dustproof assembly 2; the dustproof assembly 2 comprises an umbrella-shaped cover body 21, a support plate 22 and a sealing sleeve 23; the umbrella-shaped cover body 21 is sleeved on the oil outlet end of the sampling tube 1; the support plate 22 is inserted into the sampling tube 1 to support the umbrella-shaped cover body 21; a connector 4 is provided at one end of the support plate 22 away from the umbrella-shaped cover body 21; the sealing sleeve 23 is connected to the support plate 22 via the connector 4; the sealing sleeve 23 is sleeved on the sampling end of the sampling tube 1.

[0022] Specific implementation process: pre-sleeve the umbrella-shaped cover body 21 on the sampling tube 1, then put the support plate 22 on and screw it to the sampling tube 1 to support the umbrella-shaped cover body 21, and further connect the sealing sleeve 23 to the end of the support plate 22 away from the bulk cover body 21 through the connecting piece 4 to ensure that the oil outlet end of the sampling tube 1 is sealed in the inner cavity of the sealing sleeve 23; wherein, the use of the umbrella-shaped cover body 21 is convenient for the staff to temporarily knock, vibrate and shake off dust, thereby reducing the number of times of disassembly and cleaning; in addition, the umbrella-shaped cover body 21, the support plate 22 and the sealing sleeve 23 are all detachably screwed, which is convenient for disassembly and cleaning, repeated use, and replacement of the sealing structure in the sealing sleeve 23.

[0023] In this embodiment, the connector 4 is a threaded tube. The support plate 22 is threadedly connected to the sampling tube 1; the support plate 22 is concavely provided with a limit groove for the umbrella-shaped cover body 21 to be inserted; or the extended end of the umbrella-shaped cover body 21 is connected to the support plate 22 through an outer ring plate. In addition, in order to further ensure the sealing of the connection, a communicating sealing groove is provided between the connector 4 and the sealing sleeve 23, and the sealing groove is used to insert a sealing ring.

[0024] The use of the limit groove can prevent the umbrella-shaped cover body 21 from being displaced and moved, and is also convenient for collecting dust inside the groove for unified cleaning after vibration shaking; in addition, an outer ring plate can be used to connect the umbrella-shaped cover body 21 and the support plate 22 to directly shake off the dust.
