Description

Technical Field

[0001] The present disclosure relates to the technical field of manhole covers, and in particular to a manhole cover. Background Art

[0002] During takeoff or landing, the aircraft will taxi onto the runway or return to the designated parking position via the taxiway to avoid collision with other aircraft or ground vehicles.

[0003] In the related art, when an aircraft is taxiing on a taxiway, the engines on both sides of the aircraft wings eject high-speed, high-pressure airflow, which can easily cause the manhole cover next to the taxiway to be blown open or flipped over by the strong airflow, affecting the aircraft's taxiing safety. Utility Model Content

[0004] In view of this, the present disclosure provides a manhole cover, which can be more securely fixed to the manhole body, thereby improving the safety of aircraft taxiing.

[0005] Specifically, the present disclosure is achieved through the following technical solutions:

[0006] According to a first aspect of an embodiment of the present disclosure, there is provided a manhole cover, which is applied to a well body, and the manhole cover includes a cover body, a fastening assembly, and a locking assembly. The cover body is arranged on the well body, and the cover body is provided with a locking groove. The fastening assembly is connected to the cover body. The fastening assembly can be sleeved on the well body and fixedly connected to the outer wall of the well body to fix the manhole cover to the well body. The locking assembly includes a locking member and a reset member, the locking member can be rotatably connected to the well body, the locking member can be subjected to force to rotate relative to the well body, and cooperate with the locking groove to fix the cover body to the well body. The reset member is connected to the locking member to provide a reset force for the locking member to be disconnected from the locking groove.

[0007] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0008] When the manhole cover is in use, the cover body is placed on the manhole body to close the manhole body. The fastening assembly is sleeved on the manhole body and fixedly connected to the outer wall of the manhole body, and the fastening assembly is connected to the cover body so that the cover body and the manhole body are relatively fixed. The locking member of the locking assembly can be rotatably connected to the manhole body, and the locking member can rotate relative to the manhole body when subjected to force. For example, when the high-speed airflow gas generated by the aircraft is generated, the locking member can be subjected to wind force and rotate relative to the manhole body. When the locking member rotates, it can cooperate with the locking groove of the cover body, so that the cover body and the manhole body are further fixedly connected, reducing the possibility of the manhole cover being blown open by the strong airflow generated by the aircraft, thereby improving the safety of the aircraft taxiing on the taxiway. When the wind disappears, the locking member is no longer subjected to wind force. At this time, under the action of the reset member, the locking member is disconnected from the locking groove, so that the staff can open the cover body to open the manhole body.

[0009] The technical solution of the present disclosure will be further described below:

[0010] In one embodiment, the fastening assembly includes a connecting member and a first fastener. The connecting member can be sleeved on the well body, and the connecting member is fixedly connected to the well body through the first fastener. The cover body is rotatably connected to the connecting member to open or close the well body.

[0011] In one embodiment, the cover body is provided with a gripping member, and the cover body opens or closes the well body through the gripping member.

[0012] In one embodiment, the manhole cover further includes a second fastener. When the cover body closes the well body, the cover body can be fixedly connected to the fastening assembly through the second fastener so that the cover body and the well body are relatively fixed.

[0013] In one embodiment, a stop member is provided on the inner side wall of the locking groove. The locking member includes a locking portion that can cooperate with the stop member. When the locking member is forced to rotate relative to the well body, the locking portion can abut against the stop member to fixedly connect the cover body to the well body.

[0014] In one embodiment, the locking member further includes a connecting portion disposed opposite to the locking portion. The reset member includes a spring. One end of the spring is connected to the connecting portion, and the other end is connected to the well body to provide a reset force for the locking portion to disengage from the stop member.

[0015] In one embodiment, the distance from the locking portion to the connection point of the locking member and the well body is greater than the distance from the connecting portion to the connection point of the locking member and the well body.

[0016] In one embodiment, the locking assembly further includes a rotating shaft. The locking member is rotatably connected to the well body through the rotating shaft. The reset member further includes a torsion spring. The torsion spring includes a first torsion rod and a second torsion rod. The torsion spring is sleeved on the rotating shaft, and one of the first torsion rod and the second torsion rod is connected to the locking member, and the other is connected to the well body.

[0017] In one embodiment, the cover body is integrally formed.

[0018] In one embodiment, the diameter of the cover body is greater than the inner diameter of the well body.

Detailed implementation manners

[0028] Here, the technical solutions in the embodiments (or "implementation manners") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements.

In addition, terms such as "first" and "second" in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0030] With the development of the economy, airplanes have gradually become a common means of transportation for travel. During the takeoff or landing of an airplane, the airplane will taxi through the taxiway into the runway or return to the designated parking position to avoid collisions with other airplanes or ground vehicles. In some airports, the oil pipelines leading to the apron pipe network are laid parallel to the apron taxiway, and manhole covers are provided in these oil pipelines to discharge pollutants in the pipelines.

[0031] In the related art, during the taxiing process of an airplane on the taxiway, the high-speed and high-pressure airflow gas ejected from the engines on both sides of the airplane wing is very likely to blow open or flip the manhole cover located beside the taxiway, affecting the safety of the airplane taxiing.

[0032] Based on this, it is necessary to provide a manhole cover that can be more firmly fixed to the well body to improve the safety of the airplane taxiing.

[0033] As Figures 1 to 3 shown, the present application provides a manhole cover 100, which is applied to a well body 200. The manhole cover 100 includes a cover body 110, a fastening assembly 120, and a locking assembly 130. The cover body 110 covers the well body 200, and the cover body 110 is provided with a locking groove 111. The fastening assembly 120 is connected to the cover body 110. The fastening assembly 120 can be sleeved on the well body 200 and fixedly connected to the outer wall of the well body 200 to fixedly connect the manhole cover 100 to the well body 200. The locking assembly 130 includes a locking member 131 and a reset member 132. The locking member 131 is rotatably connected to the well body 200. The locking member 131 can rotate relative to the well body 200 under force and cooperate with the locking groove 111 to fixedly connect the cover body 110 to the well body 200. The reset member 132 is connected to the locking member 131 to provide a reset force for the locking member 131 to disengage from the locking groove 111.

[0034] Thus, when the manhole cover 100 is in use, the cover body 110 is placed on the well body 200 to close the well body 200. The fastening assembly 120 is sleeved on the well body 200 and fixedly connected to the outer wall of the well body 200, and the fastening assembly 120 is also connected to the cover body 110, so that the cover body 110 and the well body 200 are relatively fixed. The locking member 131 of the locking assembly 130 is rotatably connected to the well body 200, and the locking member 131 can rotate relative to the well body 200 when a force is applied. For example, when high-speed airflow is generated by an aircraft, the locking member 131 can be forced by the wind to rotate relative to the well body 200. When the locking member 131 rotates, it can cooperate with the locking groove 111 of the cover body 110, so as to further fixedly connect the cover body 110 and the well body 200, reducing the possibility that the manhole cover 100 is blown open by the strong airflow generated by the aircraft, thereby improving the safety of the aircraft taxiing on the taxiway. When the wind force disappears, the locking member 131 is no longer affected by the wind force. At this time, under the action of the reset member 132, the locking member 131 is disengaged from the locking groove 111, enabling the staff to open the cover body 110 to open the well body 200.

[0035] It should be noted that there are various specific implementation methods for the material of the manhole cover 100, including stainless steel, copper, copper alloy, iron, and iron alloy, etc.

[0036] It should be noted that there are various specific implementation methods for the reset member 132, including elastic reset and magnetic reset, etc. As long as it can provide a reset force for the locking member 131 to disengage from the locking groove 111.

[0037] It should be noted that there are various specific implementation methods for the shape of the cover body 110, including cylindrical shape, multiple cylinders stacked, etc.

[0038] As Figure 4 shown, in some embodiments, the fastening assembly 120 includes a connecting member 121 and a first fastener 122. The connecting member 121 can be sleeved on the well body 200, and the connecting member 121 is fixedly connected to the well body 200 through the first fastener 122. The cover body 110 is rotatably connected to the connecting member 121 to open or close the well body 200. Thus, when installing the manhole cover 100 on the well body 200, the connecting member 121 is sleeved on the well body 200, and then the connecting member 121 is fixedly connected to the well body 200 through the first fastener 122. This installation method is simple and easy to implement. And the cover body 110 and the connecting member 121 are rotatably connected, enabling the staff to open or close the well body 200 through the cover body 110.

[0039] It should be noted that there are many specific implementation methods for the first fastener 122, including but not limited to threaded fasteners such as fastening screws and fastening bolts.

[0040] AsFigure 4 As shown, in some embodiments, the cover body 110 is provided with a gripping member 112, and the cover body 110 opens or closes the well body 200 through the gripping member 112. In this way, by providing the gripping member 112 on the cover body 110, the staff can more conveniently open or close the crystal through the gripping member 112, which is beneficial to improving the use experience of the staff.

[0041] In some embodiments, the manhole cover 100 further includes a second fastener. When the cover body 110 closes the well body 200, the cover body 110 can be fixedly connected to the fastening assembly 120 through the second fastener so that the cover body 110 and the well body 200 are relatively fixed. In this way, when the staff does not need to open the manhole cover 100, the cover body 110 is closed to the well body 200, and then the cover body 110 and the fastening assembly 120 are fixedly connected by using the second fastener, so that the cover body 110 and the well body 200 are relatively fixed, thereby further reducing the possibility that the cover body 110 is blown open by the strong airflow generated by the aircraft and improving the safety of the aircraft taxiing on the taxiway.

[0042] It should be noted that there are many specific implementation manners of the second fastener, including but not limited to threaded fasteners such as fastening screws and fastening bolts.

[0043] As Figure 4 shown, in some embodiments, a stop member 101 is provided on the inner side wall of the locking groove 111. The locking member 131 includes a locking portion 102 that can cooperate with the stop member 101. When the locking member 131 is forced to rotate relative to the well body 200, the locking portion 102 can abut against the stop member 101 so that the cover body 110 is fixedly connected to the well body 200. In this way, when the high-speed airflow gas generated by the aircraft causes the locking member 131 to be affected by the wind force and the locking member 131 rotates relative to the well body 200, the locking portion 102 of the locking member 131 abuts against the stop member 101 in the locking groove 111, further ensuring the fixed connection between the cover body 110 and the well body 200 to further improve the safety of the aircraft taxiing on the taxiway.

[0044] It should be noted that there are various specific implementation manners of the stop member 101 and the cover body 110, including integrally forming the stop member 101 and the cover body 110 and separately manufacturing and then assembling the stop member 101 and the cover body 110, etc.

[0045] As Figure 4As shown, in some embodiments, the locking member 131 further includes a connecting portion 103 disposed opposite to the locking portion 102. The reset member 132 includes a spring, one end of the spring is connected to the connecting portion 103, and the other end is connected to the well body 200 to provide a reset force for the locking portion 102 to disengage from the stopper 101. In this way, by connecting one end of the spring to the connecting portion 103 and the other end to the well body 200, when the locking member 131 is stressed, the locking member 131 will rotate relative to the well body 200, causing the spring to deform and provide a reset force for the locking member 131. When the locking member 131 is no longer affected by the wind force, under the action of the reset force of the spring, the locking member 131 rotates relative to the well body 200 and disengages from the locking groove 111, so that the locking portion 102 disengages from the stopper 101, enabling the staff to open the cover body 110.

[0046] Of course, as Figure 4 shown, in some embodiments, the reset member 132 can also be a torsion spring, and the locking member 131 is rotatably connected to the well body 200 through a rotating shaft 104. The torsion spring includes a first torsion rod and a second torsion rod. The torsion spring is sleeved on the rotating shaft 104, and one of the first torsion rod and the second torsion rod is connected to the locking member 131, and the other is connected to the well body 200. In this way, the locking member 131 is rotatably connected to the well body 200 by rotation, and the torsion spring is sleeved on the rotating shaft 104. When the locking member 131 is stressed, the locking member 131 will rotate relative to the well body 200, causing relative movement between the first torsion rod and the second torsion rod of the torsion spring and generating a reset force for the locking member 131 to rotate back. When the locking member 131 is no longer affected by the wind force, under the action of the reset force of the torsion spring, the locking member 131 rotates relative to the well body 200 and disengages from the locking groove 111, so that the locking portion 102 disengages from the stopper 101, enabling the staff to open the cover body 110.

[0047] It can be understood that the locking assembly 130 can be provided with only a spring to provide a reset force for the locking portion 102 to disengage from the stopper 101, or only a torsion spring to provide a reset force for the locking portion 102 to disengage from the stopper 101, or both a spring and a torsion spring can be provided together to provide a reset force for the locking portion 102 to disengage from the stopper 101.

[0048] In the experiments of this application, the researchers found that when the wind force is slightly small, the rotation amplitude of the locking member 131 relative to the well body 200 will decrease, which may cause the locking portion 102 not to cooperate with the blocking member 101. Based on this, in some embodiments, the distance from the locking portion 102 to the connection between the locking member 131 and the well body 200 is greater than the distance from the connecting portion 103 to the connection between the locking member 131 and the well body 200. In this way, using the lever principle, when the locking member 131 is stressed, due to the fact that the distance from the locking portion 102 to the connection between the locking member 131 and the well body 200 is greater than the distance from the connecting portion 103 to the connection between the locking member 131 and the well body 200, the wind force received by the locking portion 102 will increase, which is beneficial to increasing the rotation amplitude of the locking member 131 relative to the well body 200, thereby further improving the reliability of the cooperation between the locking portion 102 and the blocking member 101.

[0049] In some embodiments, there may be multiple locking assemblies 130, which are respectively arranged at intervals along the circumference of the well cover 100. In this way, by respectively arranging multiple locking assemblies 130 at intervals along the circumference of the well cover 100, the wind in different directions can blow the locking member 131 to rotate relative to the well body 200, so as to cooperate with the blocking member 101 to fix the cover body 110 and the well body 200.

[0050] As Figure 4 shown, in some embodiments, the cover body 110 is integrally formed. In this way, the assembly process can be reduced, and the assembly efficiency of the well cover 100 can be improved.

[0051] In some areas with a lot of rain in the rainy season, in addition to preventing the well cover 100 from being blown open or flipped open, it is also necessary to prevent rainwater from entering the oil pipeline through the well cover 100, so as to avoid the influence of rainwater on the quality of the oil products in the oil pipeline. Based on this, as Figure 4 shown, in some embodiments, the diameter of the cover body 110 is greater than the inner diameter of the well body 200. In this way, by using the fact that the diameter of the cover body 110 is greater than the inner diameter of the well body 200, the cover body 110 can completely cover the well body 200, thereby preventing rainwater from entering the well body 200 and polluting the oil products in the oil pipeline.

[0052] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0053] The above embodiments only illustrate several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application.
