Description

Technical Field

[0001] This utility model relates to the field of medium and low pressure natural gas transmission and distribution technology, specifically to an indoor sewage regulation device. Background Technology

[0002] In medium- and low-pressure natural gas transmission and distribution systems, pressure regulating stations serve as critical pressure regulation facilities, and their regular maintenance is a crucial aspect of ensuring stable system operation. However, some medium- and low-pressure natural gas pressure regulating stations were not planned and constructed with supporting sewage treatment ponds during the initial design phase. This forces the pressure regulating stations to resort to on-site sewage discharge during maintenance operations. Furthermore, many pressure regulating devices are installed in brick buildings or stainless steel cabinets due to installation requirements; these enclosed or semi-enclosed installation spaces restrict gas emissions and impurity treatment during the sewage discharge process.

[0003] The aforementioned design flaws, combined with the installation environment, directly lead to a dual problem: firstly, the natural gas released during sewage discharge is difficult to expel from brick houses or stainless steel cabinets through an effective path, easily accumulating in enclosed spaces; secondly, impurities, oily wastewater, and other pollutants discharged from the natural gas pipelines cannot be collected centrally, remaining directly inside the house or cabinets. This not only poses serious safety hazards such as fire and explosion due to natural gas accumulation, but also significantly increases the difficulty and workload of subsequent cleaning due to the adhesion and accumulation of pollutants. Utility Model Content

[0004] The purpose of this invention is to provide an indoor sewage regulation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an indoor sewage regulation device, installed in a pressure regulating station and connected to a natural gas pressure regulating box, comprising:

[0006] A tank body, which is connected to the pressure regulating box, is used to load impurities from the pressure regulating station;

[0007] A top cover, which is disposed on the tank body and is used to seal the top of the tank body;

[0008] A connecting structure is provided on the tank body and connected to the top cover, and the connecting structure is used to drive the top cover to rotate and open.

[0009] Preferably, the tank body is provided with an inlet pipe and an outlet pipe, and both the inlet pipe and the outlet pipe are provided with connectors, which are used to connect with external structures;

[0010] The feed pipe is used to feed material into the tank;

[0011] The discharge pipe is used to discharge impurities from the tank.

[0012] Preferably, the tank is equipped with a pressure gauge, which is used to display the pressure inside the tank;

[0018] Preferably, the outer side of the tank is provided with at least three support feet, which are used to stabilize and support the tank.

[0019] Preferably, the top cover is provided with a handle, which facilitates lifting the tank.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This indoor sewage regulation device effectively solves the safety hazards and cleaning difficulties caused by the lack of a supporting sewage tank in medium and low pressure natural gas pressure regulating stations, resulting in on-site sewage discharge. The tank can centrally load the impurities and sludge discharged from the pressure regulating station, preventing them from directly remaining inside brick buildings or stainless steel cabinets, greatly reducing the difficulty of subsequent cleaning. The top cover, combined with the snap-fit ​​structure, can achieve a reliable seal on the top of the tank. Combined with the pressure gauge on the tank, the internal pressure can be monitored in real time to prevent natural gas leakage and accumulation during sewage discharge, which could lead to safety risks. The observation mirror facilitates a direct view of the accumulation of impurities inside the tank, which is conducive to timely maintenance. The connecting structure uses a rotating shaft and connecting plate to drive the top cover to rotate and open, making operation convenient and efficient. The connectors on the inlet and outlet pipes facilitate quick docking with the pressure regulating box and external structures, with strong adaptability. The support feet ensure the stability of the tank. The overall device has a simple structure and strong practicality, effectively improving the safety and convenience of sewage discharge operations at pressure regulating stations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a technical solution: an indoor sewage regulation device, which is installed in a pressure regulating station and connected to a natural gas pressure regulating box, comprising:

[0027] Tank 1 is connected to the pressure regulating box. Tank 1 is used to load impurities from the pressure regulating station and temporarily loads them to ensure that impurities discharged from the pressure regulating box are not directly discharged onto the ground of the pressure regulating station. Tank 1 is equipped with an inlet pipe 13 and an outlet pipe 14. Both the inlet pipe 13 and the outlet pipe 14 are equipped with connectors 6. Connectors 6 are equipped with connecting pipes and valves for controlling the feeding and discharging of tank 1. Connectors 6 are used for connecting to external structures. The inlet pipe 13 is used to feed impurities into tank 1. The feed and discharge pipes 14 are used to discharge impurities from the tank 1. The tank 1 is equipped with a pressure gauge 11, which is used to display the pressure inside the tank 1. The pressure indicates the amount of impurities loaded in the tank 1. The tank 1 is also equipped with an observation mirror 12, which is used to observe the inside of the tank 1 with the naked eye. The observation mirror 12 is used to observe the inner side of the tank 1. The outer side of the tank 1 is equipped with at least three support feet 2, which are used to stably support the tank 1 in the pressure regulating station. The support feet 2 are used to stabilize the support of the tank 1.

[0028] First, the feed pipe 13 on tank 1 is connected to the natural gas pressure regulating box via connector 6. The valve on connector 6 controls the feed opening, allowing impurities discharged from the pressure regulating box to enter tank 1 temporarily via feed pipe 13, preventing impurities from being directly discharged to the ground of the pressure regulating station. At the same time, the pressure gauge 11 on tank 1 displays the pressure inside the tank in real time, reflecting the amount of impurities loaded inside the tank. The observation mirror 12 allows for visual observation of the impurities inside tank 1. When it is necessary to discharge impurities from the tank, the discharge pipe 14 on tank 1 is connected to the external sewage discharge structure via connector 6. The valve on connector 6 is operated to discharge the impurities through discharge pipe 14. At least three support feet 2 on the outside of tank 1 always provide stable support to tank 1, ensuring that the device remains stable within the pressure regulating station throughout the sewage discharge process.

[0029] Top cover 3 is provided on tank body 1. Top cover 3 is used to seal the top of tank body 1. Top cover 3 is provided with a handle, which makes it easy to lift tank body 1.

[0030] The top cover 3 is located on the tank body 1. Its core function is to seal the top of the tank body 1. By cooperating with the tank body 1, it achieves a closed state and prevents the impurities loaded in the tank body 1 from overflowing. At the same time, the handle on the top cover 3 provides a gripping point when the tank body 1 needs to be moved, making it convenient for operators to move the tank body 1 by pulling the handle, thereby realizing convenient handling of the tank body 1.

[0031] The connecting structure 5 is located on the tank body 1 and connected to the top cover 3. The connecting structure 5 is used to drive the top cover 3 to rotate and open. The connecting structure 5 includes a second connecting seat 51 located on the tank body 1. The second connecting seat 51 is provided with a second rotating shaft 52. The second rotating shaft 52 is used to drive the connecting plate 53 to rotate, thereby driving the top cover 3 to open the tank body 1. The connecting plate 53 is connected to the second rotating shaft 52, and one side of the connecting plate 53 is connected to the top cover 3.

[0032] The connecting structure 5 is installed on the tank body 1 and is connected to the top cover 3 through the connecting plate 53. The second connecting seat 51 is fixed on the tank body 1 and provides installation support for the second rotating shaft 52. When the top cover 3 needs to be opened, the second rotating shaft 52 can rotate around its own axis. Since the second rotating shaft 52 is connected to the connecting plate 53 and the connecting plate 53 is connected to the top cover 3, the rotation of the second rotating shaft 52 will drive the connecting plate 53 to rotate synchronously, and then the connecting plate 53 will drive the top cover 3 to rotate and open.

[0033] The tank body 1 is also provided with a snap-fit ​​structure 4. There are at least four snap-fit ​​structures 4 arranged in a ring around the top of the tank body 1. The snap-fit ​​structure 4 is used to fasten the top cover 3 to the top of the tank body 1. The snap-fit ​​structure 4 includes a first connecting seat 41 on the tank body 1. The first connecting seat 41 is provided with a first connecting shaft 43. A connecting rod 42 is provided on the outside of the first connecting shaft 43. The connecting rod 42 can rotate on the first connecting shaft 43. After rotation, the snap-fit ​​plate 45 is placed on the top of the snap-fit ​​platform 44 to complete the snap-fit ​​and thus fix the top cover 3. The snap-fit ​​structure 4 also includes a snap-fit ​​platform 44 on the top cover 3. The snap-fit ​​platform 44 is provided with a snap-fit ​​groove for accommodating the connecting rod 42. The connecting rod 42 is provided with a snap-fit ​​plate 45. The snap-fit ​​plate 45 is snapped onto the top of the snap-fit ​​platform 44. The snap-fit ​​plate 45 is provided with a control handle 46 for controlling the connecting rod 42.

[0034] At least four snap-fit ​​structures 4 are provided on the top of the tank body 1 and arranged in a ring shape. They are used to fasten the top cover 3 to the top of the tank body 1. During operation, by operating the control handle 46 on the snap-fit ​​plate 45, the connecting rod 42 connected to the outside of the first connecting shaft 43 can be rotated around the first connecting shaft 43 on the first connecting seat 41. After the connecting rod 42 rotates into the snap-fit ​​groove of the snap-fit ​​platform 44 on the top cover 3, it continues to rotate so that the snap-fit ​​plate 45 is placed and snapped on the top of the snap-fit ​​platform 44, thereby achieving the fixed and secure fixation of the top cover 3.

[0035] When using the indoor sewage regulation device, it is first stabilized by at least three support feet 2 on the outside of the tank body 1. During operation, the connector 6 of the feed pipe 13 on the tank body 1 is connected to the natural gas pressure regulating box. The valve on the connector 6 is operated to open the feed, allowing the impurities discharged from the pressure regulating box to enter the tank body 1 through the feed pipe 13 for temporary loading, avoiding direct discharge to the ground of the pressure regulating station. At the same time, the pressure gauge 11 on the tank body 1 displays the pressure inside the tank in real time to reflect the amount of impurities loaded, and the condition of impurities inside the tank body 1 is observed with the naked eye using the observation window 12. The top cover 3 is closed on the top of the tank body 1 for sealing, and is secured by at least four snap-fit ​​structures 4 arranged in a ring on the top of the tank body 1. The operating mechanism on the snap-fit ​​plate 45 is then used to control the flow of the impurities. The handle 46 drives the connecting rod 42 to rotate around the first connecting shaft 43 on the first connecting seat 41, so that the connecting rod 42 enters the snap-fit ​​groove of the snap-fit ​​platform 44 on the top cover 3, and is then snapped into the top of the snap-fit ​​platform 44 by the snap-fit ​​plate 45 to complete the fixation; when it is necessary to open the top cover 3, it is achieved through the connecting structure 5: the second connecting seat 51 fixed on the tank body 1 supports the second rotating shaft 52, the second rotating shaft 52 rotates and drives the connected connecting plate 53, thereby pulling the top cover 3 to rotate and open; when it is necessary to discharge impurities, the connector 6 of the discharge pipe 14 on the tank body 1 is connected to the external sewage discharge structure, and the valve on the connector 6 can be operated to discharge impurities; when it is necessary to move the device, the tank body 1 can be lifted by the handle on the top cover 3 for convenient handling.
