Description

Technical Field

[0001] The utility model relates to the technical field of gas monitoring, in particular to an underground protection sleeve and a gas monitoring device. Background Art

[0002] The existing underground gas monitors are integrated with the protective casing and have a fixed length. They can only be fixedly buried on the ground or installed above the ground. The gas leaked from the underground gas pipe can only be detected and an alarm can be sounded after it diffuses to the equipment installation point. When the equipment needs maintenance or battery replacement, the integrated equipment needs to dig up the surrounding road surface to remove the equipment, which causes great damage to the surrounding road surface and the environment and has high maintenance costs. In addition, the buried depth of gas pipes in different regions is different (usually 0.5 to 2 meters), and there is a permafrost layer in the north in winter (the deepest permafrost layer can reach 1.6 meters), and the soil will freeze and become airtight. If the equipment can only be fixed on the ground because the casing and the equipment are integrated, it will not be able to detect small leaks in the deeply buried pipe or leaks under the permafrost layer. It cannot be detected at all, which poses a serious safety hazard. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 , Figure 2 and Figure 3The embodiment of the utility model provides an underground protective sleeve, including a tube body 1 that can be buried underground, the tube body 1 having an inner cavity 10 for detachably installing a gas monitor 2, the inner cavity 10 of the tube body 1 is provided with a fixing structure 3 for fixing a signal transmitting end 4, the signal transmitting end 4 is used to transmit the monitoring signal of the gas monitor 2, and the fixing structure 3 is installed on the tube body 1 close to the ground. In this embodiment, by designing a tube body 1 for installing the gas monitor 2, when the equipment needs maintenance or battery replacement, it is no longer necessary to dig up the surrounding road surface to remove the equipment, which is friendly to the surrounding road surface and the environment and has low maintenance costs. By designing a separate tube body 1, the length can be cut arbitrarily, and it can adapt to natural gas pipelines of any buried depth, ensuring that the monitoring equipment is always close to the gas pipeline, ignoring the airtightness of the frozen soil layer in winter, and there are no hidden dangers in gas monitoring. Specifically, when installing the buried protective sleeve underground, since the sleeve does not have equipment, not only the core equipment is damaged, but it only needs to drill a hole in the ground to install it, with low construction cost and little damage to the road surface. However, the existing integrated equipment needs to excavate the ground on a large scale first, and then bury the integrated equipment underground, and then cover and restore it. The whole process requires large construction actions, damages the environment, and has high costs. Moreover, if inspection and maintenance are required, the existing integrated equipment needs to excavate the foundation again and take out the entire equipment for inspection and maintenance. However, the sleeve of this embodiment is adopted. Since the gas monitor 2 and the sleeve are detachably connected, we only need to dig the soil layer above the sleeve, open the sleeve, and take out the gas monitor 2 for repair and maintenance. The operation is completed without damaging the environment. The maintenance cost is very low, avoiding secondary construction and accelerating the maintenance cycle, ensuring safe and long-lasting gas monitoring. In addition, since the size of the existing integrated equipment is fixed when it leaves the factory, if the gas pipeline is buried deep, in order not to affect the signal, the existing integrated equipment cannot be buried too deep, and if it is not buried deep, it is impossible to accurately monitor the situation of the gas pipeline. The present application adopts a split design, and the pipe body 1 can be cut on site as needed. The pipe body 1 can be easily cut to a suitable length by hand saws or angle grinders. The pipe body 1 can be buried near the gas pipeline to ensure that it can respond quickly when the gas pipeline leaks and is not affected by the frozen soil under the frozen soil layer. It can quickly monitor small leaks and speed up the emergency response time. Preferably, the pipe body 1 is provided with air holes 11 to facilitate the leaked gas to enter the tank body 1 for monitoring by the gas monitor 2. In addition, the air holes 11 are designed to facilitate the discharge of the accumulated water in the pipe body 1. The air holes 11 are evenly arranged on the pipe body 1. The design of the air holes 11 on the pipe body 1 does not affect the safety of the gas monitor 2. The gas safety instrument 2 itself also has protective measures. The pipe body 1 is mainly to protect the gas safety instrument 2 from being damaged by sharp objects or other objects that may damage it. Preferably, the pipe body 1 can adopt a PE round pipe, which has an inner cavity 10 and is easy to cut. The gas monitor 2 shown in this embodiment can use existing equipment and can be directly purchased.

[0023] As an optimization solution of the embodiment of the utility model, please refer to Figure 1 , Figure 2 and Figure 3 , the fixed structure 3 includes a bracket, the bracket includes a first frame 30 that can be fixed on the inner wall of the tube body 1 and a second frame 31 for the signal transmitting end 4 to be installed. In this embodiment, the fixed structure 3 can be refined into a bracket, the bracket includes a first frame 30 and a second frame 31, the first frame 30 can be a frame arranged along the tube wall, so as to be fixedly installed with the inner wall of the tube body 1, and the second frame 31 can be a frame placed horizontally in the tube body 1, so that the signal transmitting end 4 is suspended in the inner cavity 10, by arranging the frame near the outlet of the tube body 1, that is, close to the ground, so that the signal transmitting end 4 can be arranged as close to the ground as possible, so as to enhance the communication signal and ensure that the monitoring data can be transmitted smoothly. Preferably, a pin 32 is provided on the first frame 30, and a mounting position for the pin 32 to be installed on the inner wall of the tube body 1, and the bracket can be fixed on the tube body 1 through the pin 32. The mounting position can be a hole that matches the pin 32. Preferably, there are multiple mounting positions, each of which is sequentially arranged along the length direction of the tube body 1. Multiple mounting positions can be designed to facilitate adjusting the position of the bracket in the inner cavity 10 as needed. Preferably, the bracket can be a stainless steel elastic bracket, so that the pin 32 can be clamped in the mounting position of the inner wall of the tube body 1 through elastic tension.

[0024] To further optimize the above solution, please refer to Figure 1 , Figure 2 and Figure 3 , the second frame 31 has a hole for the signal transmitting terminal 4 to pass through. In this embodiment, the hole is designed on the second frame 31, which can facilitate the installation of the signal transmitting terminal 4 on the second frame 31. Preferably, a protective ring 33 is provided at the hole, and the protective ring 33 can be made of, for example, a silicone protective ring 33, which can protect the signal transmitting terminal 4, such as protecting the black paint on the surface of the antenna gain copper rod 40 from being hung off and corroded. Preferably, the signal transmitting terminal 4 includes an antenna gain copper rod 40, which is fixed in the protective ring 33, and its tail is connected to the antenna connector 8, and the antenna connector 8 is connected to the gas monitor 2 through the antenna shielding wire 5, and the internal thread at the bottom of the antenna gain copper rod 40 is connected to the external thread of the upper connector of the antenna shielding wire 5.

In this embodiment, the signboard 6 is set at the upper end of the tube body 1 to mark some information, such as the name and logo of the gas company, emergency repair telephone number, etc. The signboard 6 can be made of acrylic. Preferably, the size of the signboard 6 is larger than the diameter of the tube body 1, which can ensure that the tube body 1 will not sink below the surface under rain erosion. Preferably, the signboard 6 is fixed to the bracket by screws, and the bracket can be provided with a locking position for screw locking. The screw can be a special-shaped screw to prevent ordinary tools from opening it at will, which can effectively prevent theft and accidental damage and ensure the safety of public property. The signboard 6 can also mark the location of the equipment to facilitate finding the equipment and serve as a warning for excavation. If the gas monitor 2 needs to be maintained, just remove the special-shaped screws with a special-shaped wrench, then remove the antenna bracket with a clip, and directly take out the equipment for maintenance operation without moving the tube body 1 buried underground. After maintenance, put the equipment back as it is, cover it with the signboard 6 and tighten the screws.
