Description

Technical Field

[0001] This utility model relates to the field of aviation airport engineering technology, specifically a self-alarm manhole cover for apron valve wells. Background Technology

[0002] As an important component of the airport's underground pipeline system, apron valve wells typically house valves for critical pipelines such as fuel, fire protection, and drainage. Their normal operation is crucial for the safe operation of the airport.

[0003] Self-alarm apron valve well covers generally consist of a cover body, monitoring sensors, signal processing modules, alarm devices, and a power supply system. The cover body is made of high-strength composite materials or metal to ensure load-bearing capacity and durability. The monitoring sensors typically include displacement sensors, tilt sensors, and vibration sensors, which can detect changes in the position and angle of the cover and abnormal vibrations in real time.

[0004] However, in actual use, the above-mentioned equipment lacks an automatic alarm function and can only rely on manual periodic inspections to check the condition of the manhole covers. With a large apron area and a large number of manhole covers, manual inspections are inefficient and costly, and there are situations where problems cannot be detected in time during the inspection intervals, making it difficult to ensure the continuous safety of apron operations. In view of this, we propose a self-alarming manhole cover for apron valve wells. Utility Model Content

[0005] The purpose of this utility model is to provide a self-alarming manhole cover for apron valve wells to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-alarming manhole cover for apron valve wells includes a cover body, an anti-slip groove formed on the cover body, a sealing ring fixedly installed at the bottom of the cover body, a reinforcing rib fixedly installed at the bottom of the cover body, and an installation assembly provided on the cover body, the installation assembly including:

[0008] A right-angle frame is fixedly installed below the manhole cover body, and a sliding cylinder is slidably installed on the right-angle frame. An alarm body is fixedly installed at the bottom of the sliding cylinder.

Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A self-alarm type manhole cover for apron valve well includes a manhole cover body 1, an anti-slip groove 2 on the manhole cover body 1, a sealing ring 3 fixedly installed at the bottom of the manhole cover body 1, and a reinforcing rib 4 fixedly installed at the bottom of the manhole cover body 1.

[0033] In one embodiment of this utility model, a mounting assembly 5 is provided on the manhole cover body 1. The mounting assembly 5 includes a right-angle bracket 51. The right-angle bracket 51 is fixedly installed below the manhole cover body 1. A slide cylinder 52 is slidably installed on the right-angle bracket 51. An alarm body 53 is fixedly installed at the bottom of the slide cylinder 52. A threaded cylinder 54 is fixedly installed on the alarm body 53. A screw 55 is threaded onto the threaded cylinder 54. A threaded hole 56 is provided on the right-angle bracket 51. A mounting cylinder 57 is fixedly installed at the top of the slide cylinder 52. One end of a spring 58 is fixedly installed inside the mounting cylinder 57. A ball-head positioning rod 59 is fixedly installed at the other end of the spring 58. A positioning hole 510 is provided on the right-angle bracket 51. Multiple sets of threaded cylinder 54, screw 55, threaded hole 56, mounting cylinder 57, spring 58, ball-head positioning rod 59 and positioning hole 510 are provided. The spring 58 and ball-head positioning rod 59 are located inside the mounting cylinder 57. The circular cross-section of the ball-head positioning rod 59 is the same size as the circular cross-section of the positioning hole 510. The screw 55 is threaded through the threaded cylinder 54 and threadedly installed in the threaded hole 56. The alarm body 53 is located at the center of the bottom of the manhole cover body 1.

[0034] In this embodiment, before installing the alarm body 53, the right-angle bracket 51 is first fixed below the manhole cover body 1 to provide a stable support foundation for the entire installation structure. Based on the specific layout and installation requirements of the valve well, the position of the sliding cylinder 52 on the right-angle bracket 51 is adjusted. After the position is adjusted, the alarm body 53 is fixed. Multiple sets of threaded cylinders 54 are fixed to the alarm body 53. Screws 55 are passed through the threaded cylinders 54 and threaded into the corresponding threaded holes 56 on the right-angle bracket 51. By rotating the screws 55, the connection between the threaded cylinders 54 and the right-angle bracket 51 gradually tightens, thus firmly fixing the alarm body 53 to the right-angle bracket 51. During installation, when the sliding cylinder 52 moves to the appropriate position, the ball-head positioning rod 59, under the elastic force of the spring 58, precisely... The positioning hole 510 further enhances the stability of the alarm body 53. At the same time, the spring 58 acts as a buffer, reducing the impact of external vibrations on the alarm body 53 and ensuring stable operation of the alarm in daily use. When the manhole cover body 1 is in the normally closed state, the alarm body 53 is in standby mode. Once the manhole cover body 1 is opened or subjected to abnormal external forces (such as improper opening, violent vibration, etc.), the alarm body 53 installed at the center of the bottom of the manhole cover body 1 will sense these changes. Since the alarm body 53 and the manhole cover body 1 are tightly connected through the mounting component 5, the state change of the manhole cover body 1 will be transmitted to the alarm body 53, and the alarm body 53 will then sound an alarm to remind the apron staff to pay attention and ensure the safety of apron operations.

[0035] In one embodiment of this utility model, an auxiliary component 6 is provided on the right-angle frame 51. The auxiliary component 6 includes a rubber strip 61. The rubber strip 61 is fixedly installed at the bottom of the manhole cover body 1. A hinge frame 62 is fixedly installed on the mounting cylinder 57. Each hinge frame 62 is rotatably mounted with a roller 63. A slot 64 is opened on the right-angle frame 51. An elastic strip 65 is fixedly installed on the right-angle frame 51. An arc-shaped blocking block 66 is fixedly installed on the elastic strip 65. Multiple sets of hinge frames 62, rollers 63, slots 64, elastic strips 65 and arc-shaped blocking blocks 66 are provided. A sliding cylinder 52 is arranged between multiple sets of arc-shaped blocking blocks 66. The elastic strip 65 and arc-shaped blocking blocks 66 are arranged above the slots 64. The hinge frame 62, rollers 63, slots 64, elastic strips 65 and arc-shaped blocking blocks 66 are arranged below the rubber strip 61. The rollers 63 are attached to the rubber strip 61.

[0036] In this embodiment, multiple sets of rollers 63 rotate simultaneously against the rubber strip 61. The rotation of the rollers 63 reduces friction between the manhole cover and the alarm body 53, preventing wear on the edges of the manhole cover and valve well during frequent opening and closing, thus extending their service life. The right-angle frame 51 has a slot 64 to provide installation space for the elastic strip 65 and the arc-shaped blocking block 66. When the slide cylinder 52 slides on the right-angle frame 51, the arc-shaped blocking block 66 limits the slide cylinder 52, preventing it from sliding excessively and detaching from the right-angle frame 51 or affecting the normal installation position of the alarm body 53. The elastic strip 65 provides a certain elastic buffer. When the slide cylinder 52 is subjected to external impact or moves too fast, the elastic strip 65 will undergo elastic deformation, buffering the impact force on the slide cylinder 52, further stabilizing the slide cylinder 52, enhancing the stability of the slide cylinder 52 in the installation assembly 5, ensuring the stable installation of the alarm body 53, and improving the overall performance of the self-alarm type apron valve well cover.

[0037] All electrical components appearing in this application are electrically connected to the controller and power supply. The controller is a conventional and known device that can control the alarm body 53. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
