Description

Technical Field

[0001] The utility model relates to the field of airport lighting fixtures, in particular to an underground bucket. Background Art

[0002] With the continuous increase in aviation business volume, the increasing airport throughput and the control of airport operating costs, since there are multiple navigation lights installed on the airport runway, in order to facilitate the staff to control the navigation lights, strict requirements are placed on the installation and quality of the navigation lights. The airport's control mechanism leads to power lines, which are electrically connected to multiple navigation lights on the airport's waterway. The power lines are mainly used to energize the navigation lights, and the power lines also have the function of transmitting signals to the navigation lights. Underground navigation lights are a common type of navigation lights at airports, and they play a vital role in guiding vehicles within the airport. However, existing underground navigation lights are prone to extending from the ground, rotating, and the strength of the navigation lights themselves is insufficient. The above-mentioned situation seriously affects the daily use of the navigation lights, so how to optimize the structure of the navigation lights is an urgent problem to be solved.

[0003] Chinese patent document CN104696810A discloses an "airport navigation light". The airport navigation light includes a lamp housing, a fixing plate, multiple light sources, multiple lenses and a transparent part. The fixing plate is fixed to one end of the lamp housing, the transparent part is fixed to the other end of the lamp housing, the multiple light sources are distributed on the fixing plate, the multiple lenses are respectively located between the corresponding light sources and the transparent part and fixed on the light path of the corresponding light sources, and the multiple lenses are used to refract the light emitted by the light source to form collimated light rays. However, the navigation light involved in this patent still has the problem of insufficient installation firmness and poor strength. Summary of the invention

The underground barrel of the patent is provided with an upper fixing pattern at the top of the barrel body and a plurality of grooves in the upper fixing pattern, and a bottom fixing pattern is provided at the bottom of the barrel body. The combination of the upper fixing pattern, the bottom fixing pattern and the groove ensures that the underground barrel will not be ejected from the ground due to vibration when buried underground. The load-bearing column arranged in the barrel body can greatly support the barrel body itself and strengthen the strength of the barrel body.

[0005] The above technical problems of the utility model are mainly solved by the following technical solutions: the utility model comprises a barrel body, a fixed part is provided at the edge of the barrel body, a hollow groove which passes upward is provided in the barrel body, a load-bearing column is provided on the side wall of the hollow groove, a first step surface is provided above the hollow groove, and a braces opening is provided on the first step surface.

[0019] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] Embodiment: The underground barrel of this embodiment, the rapid development of aviation industry has further increased the demand for navigation lights. Due to the particularity of channel guidance and the requirement for accuracy of channel guidance, very high requirements are placed on the durability and stability of underground lamps. Underground navigation lights are a type of navigation lights, which play a vital role in the field of aircraft navigation. However, existing navigation lights have the problems of insufficient strength, easy to be vibrated and protrude from the ground during use, and inconvenient installation. The above problems have affected the service life and stability of underground navigation lights to a certain extent. Therefore, in order to solve the above problems, this patent improves the existing problems by improving the structure of the underground navigation light barrel. Figure 1 and Figure 2As shown, the underground navigation light housing is an underground barrel. In this embodiment, the underground barrel body itself is cylindrical, and an empty groove is dug in the underground barrel body. The empty groove is upwardly connected. A number of bearing columns are arranged on the barrel wall surrounding the edge of the empty groove, and the distance between adjacent bearing columns is the same. A first step surface is arranged at a certain distance from the top of the barrel body, and the first interface is annular. The bearing columns are respectively connected to the bottom of the barrel body and the first step surface. The cross section of the bearing column is triangular, and the whole is a triangular prism. Due to the hollowing out of the barrel body, the rigidity strength of the barrel body itself is reduced. When buried underground, it is easy to be squeezed and deformed by the soil. Therefore, a number of bearing columns are arranged around the barrel wall to enhance the rigidity of the underground barrel body, so that the barrel body will not easily be squeezed and deformed. The bearing column of the triangular prism itself has higher stability and strength, which can further enhance the rigidity and strength of the barrel body. A circular bottom opening is dug in the center of the bottom end of the barrel body, so that workers can connect the wires from below when installing the underground navigation light to ensure the normal use of the navigation light. Several fixing ports are arranged around the bottom opening. After the bottom wire of the navigation light is connected and installed, the fixing parts are screwed into the corresponding fixing ports to close the barrel body, ensuring the normal operation of the barrel body. The bottom end will not be loose and affect the normal operation of the navigation light. The barrel body of the buried barrel is cylindrical. Due to the actual light direction requirements, the top cover of the barrel body needs to determine the installation direction, and then install the top cover. If the installation structure is not affected, it is easy to cause the top cover to be unable to be installed according to the established position. The barrel body itself is buried underground. After the installation, the way of rotating the barrel body to change the light direction affects the layout of the wires and the difficulty of rotation. Therefore, several bayonet ports are arranged at equal angles near the top of the barrel wall, and the bayonet position is higher than the first step surface. At the same time, the top of the barrel body has a certain width, and an installation guide groove is arranged on the inner side of the top, and the installation guide groove passes through the top of the bayonet. Through the bayonet and the installation guide groove, the staff can quickly embed and install the top cover according to the actual top cover direction requirements, thereby improving the installation efficiency of the buried navigation light. The installation guide groove also plays the role of a guide rail, guiding the rotation of the top cover during installation, reducing the installation burden of the staff. The top cover is aligned with the bayonet position, and there is a corresponding protrusion on the top cover that sinks into the bayonet to determine the position. The bayonet can also determine the position of the top cover after the top cover is installed to prevent the top cover from rotating and offsetting, thereby affecting the use of the navigation light. A number of tooth braces are provided on the first step surface, and stainless steel tooth braces are provided in the tooth braces. The actual installation environment of the underground navigation light is near the airport runway. Since the aircraft body itself is large, the ground will be subjected to greater impact and vibration during take-off and landing. Conventional fixation is prone to the problem of loosening or even separation of the fixings and the fixing ports during high-frequency and high-impact vibration. Once the fixings are loose, it is very easy to cause the direction of the navigation light to change, which in turn leads to errors in the navigation signal, and ultimately endangers the safety of people in the airport. Therefore, in this embodiment, a stainless steel tooth brace is provided in the tooth brace of the first step surface, and a double-stacked self-locking gasket is used to greatly improve the locking effect and prevent the fixings of the underground navigation light from loosening due to the vibration of the aircraft taking off and landing.At the same time, due to the need to install lighting equipment in the barrel, a large hollow groove is dug in the center of the barrel, and the barrel wall is relatively thin, resulting in insufficient rigidity of the barrel itself. In addition to the load-bearing columns set on the barrel wall, the wall thickness of the barrel itself must be greater than 6mm to meet the pressure of the barrel itself to prevent the soil from squeezing toward the center of the barrel body and reduce the deformation of the barrel.

[0021] In addition to the problem of insufficient strength of the underground barrel body, existing underground navigation lights also have the problem that the barrel body is easily turned and extended from the ground due to vibration. During the take-off and landing of the aircraft, the surrounding ground will vibrate with high frequency and high impact, and the underground navigation lights installed around the runway will be most directly affected. Although the cylindrical shape of the underground barrel body increases its own rigidity and is not easily squeezed and deformed by the external environment, during the vibration process, the cylindrical barrel body is prone to rotate and extend out of the ground due to its own smooth shape. However, in the airport, the underground navigation lights at any position have fixed light directions. Once the barrel body rotates or extends out of the ground, the light direction changes randomly, which greatly affects the progress of the pilotage work. The frequent rotation and extension of large-scale barrels from the ground not only increases the maintenance burden of maintenance personnel, but also causes the navigation light to be in the wrong direction, endangering the lives of relevant personnel. Figure 3 and Figure 4As shown, in order to solve the problem that the barrel body is prone to rotation due to vibration, in this embodiment, an upper fixing groove is arranged around the top edge of the cylindrical barrel body, grooves are arranged in the upper fixing groove at equal distances, and a bottom fixing groove is arranged at the bottom of the barrel body. Since the upper fixing groove is arranged at the top of the barrel body and the lower fixing groove is arranged at the bottom of the barrel body, the diameters of the upper and lower ends of the barrel body are greater than the diameter of the middle part of the barrel body. When the barrel body is buried underground, the soil will fill the middle part of the upper fixing groove and the bottom fixing groove. The design of the concave structure will cause the soil to produce a corresponding force. When the buried barrel tends to move upward due to the vibration of the aircraft take-off and landing, the soil in the middle part of the buried barrel body that is relatively deeply sunken will give a downward reaction force to the bottom fixing groove at the bottom of the barrel body due to the stability of its own position. Under the influence of this reaction force, the frequency of the buried barrel body extending out of the ground due to vibration during the take-off and landing of the aircraft is reduced. After the grooves are evenly spaced in the middle of the upper fixed pattern, when the barrel is installed and buried underground, a part of the soil sinks into the grooves and the concave lines in the middle of the upper fixed pattern, increasing the contact area between the top of the barrel and the soil, increasing the friction of the barrel's rotation, and the irregular top edge shape further enhances the friction between the soil and the barrel. When the buried barrel is affected by the vibration of the aircraft taking off and landing and wants to rotate, the soil deep in the concave part of the upper fixed pattern and the groove will give the groove and the upper fixed pattern a force in the opposite direction of the barrel's rotation due to its own stability, preventing the barrel from rotating due to the vibration. Therefore, after the barrel in this embodiment is buried underground, it is not easy to rotate due to the vibration generated by the aircraft taking off and landing, causing the light to deviate, interfering with the daily navigation process of the navigation light.

[0022] When the underground barrel body of this embodiment is used in actual installation work: after determining the installation position, find an underground barrel body that is suitable for the size of the installation opening, install the lighting equipment in the empty slot of the barrel body and connect it with the wire through the bottom opening at the bottom end. After the connection is completed, use fasteners to install it in the fixed opening around the bottom opening. After completion, bury the barrel body in the pit, and then cover the top cover on the top of the barrel body. The top cover rotates along the installation guide groove to the set position. The pre-set protrusion on the top cover is embedded in the bayonet. The top cover and the barrel body are fastened by using fasteners through the brace opening on the first step surface to achieve the installation of the underground navigation light barrel body. After the installation is completed, turn on the power supply, and the underground navigation light works normally.

[0023] The buried navigation light in this embodiment improves the structural strength and installation stability of the buried navigation light by improving the structure of the barrel itself. A number of triangular prism-shaped load-bearing columns are set in the buried barrel to give the barrel wall a certain support force, enhance the rigidity of the barrel itself, and set a certain barrel thickness to enhance the structural strength of the barrel itself. At the same time, the upper fixing grooves and grooves are set at the top of the barrel and the bottom fixing grooves are set at the bottom to increase the friction of the barrel during the rotation process, so that the buried barrel in this embodiment has a higher structural strength and will not be squeezed and deformed by the soil. At the same time, when subjected to the vibration of aircraft take-off and landing, it maintains a stable working state and is not prone to protruding from the ground and rotating, thereby reducing the impact on normal pilot work.
