Description

Technical Field

[0001] The utility model belongs to the technical field of rubber component structures, and in particular relates to a protective end cover for pipeline equipment. Background Art

[0002] The protective end cap used for pipeline equipment refers to the protective cover installed on the exposed end of the pipeline. The main functions of the above protective end cap are two: to ensure smooth flow of gas in and out of the pipeline and to prevent small animals from entering as much as possible.

[0003] Generally, the protective end cap is an integrally formed rubber part, and its structural components mainly include: a mounting ring and a baffle. The mounting ring is connected to the pipeline, and the baffle appropriately blocks the middle opening of the mounting ring to ensure that gas can enter and exit, and small animals are difficult to enter.

[0004] For example, a Chinese utility model patent with authorization announcement number CN207368631U and authorization announcement date 2018.05.15 discloses a cable entry sealing cover for a UCP cabinet between cabinets, including a cover tube inserted into a preset cabinet hole, the cover tube is a cylindrical structure with openings at both ends, the upper end of the cover tube is connected to a cover outer ring, the cover outer ring is an annular structure with a diameter larger than the cover tube, a number of buckles are connected to the outer wall of the cover tube, and at least one layer of a plugging cap structure for sealing the upper opening of the cover tube is arranged inside the cover tube.

[0005] The sealing cover plate in this utility model patent has the following advantages: simple structure, low cost, very convenient operation for on-site personnel, and can effectively prevent small animals from entering the cabinet room, ensuring the safe and stable operation of the natural gas long-distance pipeline.

[0006] However, in actual use, the sealing cover plate still has at least the following two shortcomings, which are also the technical problems to be solved by the present utility model, namely:

[0007] 1. The horizontal projection of the blocking cap structure cannot completely cover the middle opening of the cover plate, so the effect of blocking small animals is average, and debris is relatively easy to enter;

[0008] 2. The connection size of the central part of the plugging cap structure is small, the connection strength is low, and it is easy to break.

[0009] Therefore, in summary, there is an urgent need for a new type of protective end cover with fully covered opening area and strong connection strength of the covering structure itself, so as to be used on various pipes with exposed ports. Utility Model Content

[0010] The utility model provides a protective end cover for pipeline equipment, which can be arranged on an open hole ring unit. The method of extending the pipe unit and a plurality of inclined plates is to achieve the following: 1. The plurality of inclined plates are together to ensure that the total lateral projection can completely cover the extending pipe unit, thereby increasing the difficulty of small animals and debris entering the pipeline; 2. At least two ends of the inclined plate are connected to the extending pipe unit, so that it has a higher connection strength.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problem is: a protective end cover for pipeline equipment, the structure of which includes an open hole ring unit for connecting the pipeline, an open extension pipe unit arranged on the open hole ring unit, and a plurality of inclined plates at least two ends of which are arranged on the inner annular surface of the open extension pipe unit and the lateral projection completely covers the open extension pipe unit.

[0012] A further preferred technical solution is that the perforated ring unit comprises a rectangular ring body and a circular hole provided on the rectangular ring body and used for installing a bolt.

[0013] A further preferred technical solution is that the perforated ring unit further includes a rectangular inner ring disposed on the rectangular ring body and used for engaging with the inner side surface of the pipe.

[0014] A further preferred technical solution is that the perforated ring unit further includes a rectangular outer ring disposed on the rectangular ring body and used for engaging with the outer side surface of the pipe.

[0015] A further preferred technical solution is that the open extension tube unit includes a rectangular tube which is arranged on the opening of the rectangular ring body and is used to increase the distance between adjacent inclined plates and extend the gas channel formed between the inclined plates.

[0016] A further preferred technical solution is that the open extension tube unit also includes a protruding block arranged on the lower surface of the rectangular tube and used to set the upper and lower installation edge orientation prompt words of the protective end cover.

[0017] A further preferred technical solution is that the open extension tube unit further includes a bolt anti-drop protection block which is arranged on the outer annular surface of the rectangular tube and is used to prevent the bolt from loosening.

[0018] A further preferred technical solution is that the number of the inclined plates is 4-10, the shape of the inclined plates is rectangular, and the inclined plates are arranged parallel to each other.

[0019] A further preferred technical solution is that: among two adjacent inclined plates, the height of the lower side of the upper inclined plate is lower than the height of the upper side of the lower inclined plate.

[0020] A further preferred technical solution is that the difference in number of the circular holes on the upper and lower mounting edges of the rectangular ring body is at least 1. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0032] As attached Figure 1-6 As shown, a protective end cover for pipeline equipment includes an open hole ring unit 1 for connecting a pipeline a, an open extension pipe unit 2 arranged on the open hole ring unit 1, and a plurality of inclined plates 3 at least two ends of which are arranged on the inner annular surface of the open extension pipe unit 2 and the lateral projection completely covers the open extension pipe unit 2.

[0033] In this embodiment, the perforated ring unit 1, the open extension pipe unit 2 and the inclined plate 3 are integrally formed and made of common rubber. The protective end cap is used for the pipe a or the opening of the pipe equipment, and the shape and size of the pipe a and the opening are ensured to correspond to the perforated ring unit 1.

[0034] The functions of the open extension tube unit 2 mainly include the following two aspects:

[0035] First, the distance between adjacent inclined plates 3 is increased so that the pipeline equipment has a larger air inlet and outlet area;

[0036] Second, the gas passage formed between the inclined plates 3 is extended, so that it is more difficult for small animals and debris to enter the pipe a.

[0037] In addition, the upper and lower sides of the inclined plates 3 are both horizontal, but the entire plate is tilted so that the sum of the lateral projections of all the inclined plates 3 can completely cover the open extension pipe unit 2, further preventing small animals from entering.

[0038] Finally, in order to prevent leaves and other fallen objects from falling into the pipe a as much as possible, the upper and lower faces of the protective end cover are restricted, that is, the outer port of the gas channel formed between the inclined plates 3 must face downward and cannot face upward.

[0039] The perforated ring unit 1 includes a rectangular ring body 101 and a circular hole 102 disposed on the rectangular ring body 101 and used for installing a bolt b.

[0040] In this embodiment, the rectangular contour and rectangular opening of the rectangular ring body 101 can be chamfered as needed. The circular hole 102 does not need to be threaded, and the bolt groove on the pipe a has preset threads to ensure that the bolt b can effectively install the protective end cover.

[0041] The perforated ring unit 1 further includes a rectangular inner ring 103 which is arranged on the rectangular ring body 101 and is used for engaging with the inner side surface of the pipe a.

[0042] The perforated ring unit 1 further includes a rectangular outer ring 104 disposed on the rectangular ring body 101 and used for engaging with the outer side surface of the pipe a.

[0043] In this embodiment, the perforated ring unit 1 can be divided into the following four categories according to whether it is engaged with the pipe a:

[0044] First, there is no snap-fit ​​structure, and positioning is performed only by the circular hole 102;

[0045] Second, there is a snap-fit ​​structure, and only the rectangular inner ring 103 is provided;

[0046] Third, there is a snap-fit ​​structure, and only the rectangular outer ring 104 is provided;

[0047] Fourth, there is a snap-fit ​​structure, and the rectangular inner ring 103 and the rectangular outer ring 104 are provided at the same time.

[0048] The above four types of perforated ring units 1 all have their applicable conditions and their own advantages and disadvantages. For example, the alignment operation of the perforated ring unit 1 of the fourth structural style is relatively simple during installation, but its applicable scope is relatively small and its applicability is not as good as the above three types.

[0049] The open extension pipe unit 2 includes a rectangular pipe 201 which is arranged on the opening of the rectangular ring body 101 and is used to increase the distance between adjacent inclined plates 3 and extend the gas channel formed between the inclined plates 3 .

[0050] In this embodiment, the rectangular outline size and shape of the outer annular surface of the rectangular tube 201 are determined by the rectangular opening of the rectangular ring body 101. The length and width of the inner annular surface of the rectangular tube 201 are determined by itself, and it is optional whether to have chamfers.

[0051] At this point, the rectangular tube 201 upgrades the originally "dense, oblique and short" inclined plate 3 to "relatively sparse, relatively flat and relatively long", thereby increasing the air permeability area and extending the length that small animals and debris need to pass through to enter the pipeline. Figure 6 .

[0052] The open extension tube unit 2 further includes a protruding block 202 disposed on the lower surface of the rectangular tube 201 and used to set the upper and lower mounting edge orientation prompt words of the protective end cover.

[0053] In this embodiment, the upper and lower installation edges of the protective end cover may be oriented in a prompting manner, such as "this side faces downward". The lower surface refers to the side of the protective end cover that faces downward when it is correctly installed, i.e., the side of the outer opening of the gas passage formed by the inclined plate 3, i.e., the side of the attached Figure 3 The lower surface of the rectangular tube 201.

[0054] The upper and lower mounting edges of the protective end cover face the prompting words in order to prevent the outer opening of the gas passage from facing upward, otherwise leaves and other debris may easily float in.

[0055] The function of the protruding block 202 is to prevent the prompt words from occupying the thickness of the rectangular tube 201 during molding and to prevent it from reducing the structural strength of the rectangular tube 201 .

[0056] The open extension pipe unit 2 further includes a bolt anti-drop protection block 203 which is arranged on the outer circumferential surface of the rectangular pipe 201 and is used to prevent the bolt b from being loosened.

[0057] In this embodiment, the entire protective end cover has a certain elasticity, including the bolt anti-drop protection block 203. When the bolt b is normally disassembled, the bolt anti-drop protection block 203 needs to be manually bent to ensure that the bolt b can be smoothly inserted and removed.

[0058] The function of the bolt anti-drop protection block 203 is that when the bolt b is loosened by being twisted outward, it can block the head of the bolt b to prevent the loosening range from further increasing, or at least prevent the bolt b from falling and being lost due to complete loosening.

[0059] In other words, when the head of the bolt b abuts against the bolt anti-drop protection block 203, the bolt b is still screwed to the pipe a, but the screwing strength is reduced.

[0060] Finally, the bolt anti-drop protection blocks 203 are provided in plurality, corresponding one to one with the number of positions of the circular holes 102, or a complete annular block is directly provided to block and protect all the bolts b.

[0061] The number of the inclined plates 3 is 4-10, the shape is rectangular, and they are arranged parallel to each other.

[0062] In this embodiment, the top and bottom inclined plates 3 are connected to the inner annular surface of the rectangular tube 201 through three side edges, while the other two ends of the middle inclined plates 3 are respectively connected to the inner annular surface of the rectangular tube 201, ultimately ensuring that all the inclined plates 3 can be stably installed without weak structural strength.

[0063] Of the two adjacent inclined plates 3 , the height of the lower side of the upper inclined plate 3 is lower than the height of the upper side of the lower inclined plate 3 .

[0064] In this embodiment, when looking directly at the protective end cover, the rectangular opening of the rectangular ring body 101 is completely covered because the inclined plates 3 are stacked in sequence, and there is an overlapping area of ​​lateral projection between two adjacent inclined plates 3, which ultimately makes it difficult for debris to be blown into the pipe a.

[0065] The difference in number of the circular holes 102 on the upper and lower mounting edges of the rectangular ring body 101 is at least one.

[0066] In this embodiment, the long sides of the rectangular ring body 101 are upper and lower mounting edges, and the number of the two groups of circular holes 102 on the upper edge is not equal. For example, three circular holes 102 are set at the upper mounting edge and two circular holes 102 are set at the lower mounting edge. A total of five circular holes 102 are staggered with each other.

[0067] This method is to correctly install the protective end cover to prevent the outer port of the gas channel formed by the inclined plate 3 from facing upward. Of course, the bolt holes on the pipeline a must also be correctly opened at this time. In other words, the pipeline a also has a unique correct upper and lower surface orientation restriction.

[0068] The purpose of this method is consistent with that of the protruding block 202. The former is an "active restriction" for the correct selection of the upper and lower mounting edges of the protective end cover, and the latter is a "passive reminder".

[0069] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
