Description

Technical Field

[0001] This utility model relates to the field of coal mine safety equipment technology, specifically a negative pressure audible and visual alarm device for coal mine gas extraction pump stations. Background Technology

[0002] Coal mine gas extraction pumping stations are key facilities in coal mine safety production, mainly used to extract underground gas (coalbed methane), reduce mine gas concentration, and simultaneously achieve the recovery and utilization of clean energy. Based on underground production needs, surface gas extraction pumping stations are essential equipment. During operation, the gas extraction pumps in surface gas extraction pumping stations may experience abnormalities such as broken impeller pins, water outages, power outages, etc. During breaks in personnel patrols, the gas extraction pumps may be stopped for extended periods, leading to system shutdown and potentially causing underground gas levels to exceed limits. Therefore, this application proposes a negative pressure audible and visual alarm device for coal mine gas extraction pumping stations to address these problems. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a negative pressure audible and visual alarm device for coal mine gas extraction pumping stations, which solves the technical problems mentioned in the background.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a negative pressure audible and visual alarm device for a coal mine gas extraction pump station, comprising multiple electrical contact pressure gauges, each of which is installed on a gas pipeline inlet pipe, and each of which is electrically connected to an audible and visual alarm, which is powered by the pump station's 127V power supply, and a rapid alarm identification structure is also provided between the multiple audible and visual alarms.

[0007] Preferably, multiple sound and light alarms are mounted on a mounting plate, and multiple sound and light alarms are installed in the duty room via the mounting plate.

[0008] Preferably, the distance between the plurality of said audible and visual alarms is greater than 20cm.

[0009] Preferably, the alarm rapid identification structure includes multiple numerical codes and multiple rings, with each numerical code corresponding to a multiple audible and visual alarm, and the multiple rings are positioned outside the corresponding audible and visual alarm and numerical code, and are mounted on a mounting plate.

[0010] Preferably, the plurality of numerical numbers, starting with the number 1, correspond to the gas pipeline inlet pipes respectively, and the numerical numbers are luminous characters, and the numerical numbers are electrically connected to the corresponding audible and visual alarms.

[0011] (III) Beneficial Effects

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This type of negative pressure audible and visual alarm device for coal mine gas drainage pump stations uses an electric contact pressure gauge installed on the gas pipeline inlet pipe. The electric contact pressure gauge is electrically connected to the audible and visual alarm in the duty room. When the negative pressure in the gas pipeline inlet pipe is lower than the set value during the operation of the gas drainage system, the contacts in the electric contact pressure gauge are connected, triggering the audible and visual alarm. Real-time monitoring of the gas pipeline inlet pipe can be achieved in the duty room to ensure the normal operation of the gas drainage pump.

[0014] 2. This type of negative pressure audible and visual alarm device for coal mine gas extraction pump stations, through its alarm rapid identification structure, triggers the audible and visual alarm, and the corresponding number illuminates synchronously. The ring design visually unifies the audible and visual alarm with the corresponding number, creating a visual connection. Personnel in the control room can quickly observe the number corresponding to the audible and visual alarm, identify the corresponding gas pipeline inlet pipe, and achieve rapid identification of the triggered alarm. This avoids incorrect identification of the gas pipeline inlet pipe in emergency situations, ensuring rapid and accurate alarm identification. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1As shown, this utility model provides a technical solution: a negative pressure audible and visual alarm device for a coal mine gas extraction pump station, including multiple electrical contact pressure gauges 1, which are respectively installed on multiple gas pipeline inlet pipes 2, and each of the multiple electrical contact pressure gauges 1 is electrically connected to an audible and visual alarm 3. The audible and visual alarm of the audible and visual alarm 3 can be more easily identified in a noisy duty room. The electrical contact pressure gauges 1 are installed on the gas pipeline inlet pipes 2, and the electrical contact pressure gauges 1 are set with gas pipeline... The minimum negative pressure in the air inlet pipe 2 is set below the set value of the electric contact pressure gauge 1 during the operation of the gas extraction system. This causes the contact in the electric contact pressure gauge 1 to conduct, triggering the corresponding audible and visual alarm 3. Multiple audible and visual alarms 3 are mounted on the mounting plate 4 and installed in the duty room via the mounting plate 4. The distance between the multiple audible and visual alarms 3 is greater than 20cm. This spacing ensures that the multiple audible and visual alarms 3 are separated, preventing multiple alarms from malfunctioning simultaneously. For easy identification, multiple audible and visual alarms 3 are powered by the 127V power supply 5 of the pump station. A rapid alarm identification structure is also installed between the multiple audible and visual alarms 3. This structure includes multiple numerical numbers 6 and multiple rings 7, with each numerical number 6 corresponding to one of the multiple audible and visual alarms 3. The rings 7 are positioned outside the corresponding audible and visual alarms 3 and numerical numbers 6, and are mounted on the mounting plate 4. The rings 7 also provide visual consistency between the audible and visual alarms 3 and their corresponding numerical numbers 6, serving as a visual link. The multiple numerical numbers 6, starting from number 1, correspond to multiple gas pipeline inlet pipes 2, and are numbered 1, 2, 3... The numerical numbers 6 are illuminated and electrically connected to the corresponding audible and visual alarms 3. When an audible and visual alarm 3 is triggered, the corresponding numerical number 6 will light up synchronously. Personnel in the duty room can quickly observe the numerical number 6 corresponding to the audible and visual alarm 3 and determine the corresponding gas pipeline inlet pipe 2 for handling.

[0019] The operational steps for this application are as follows:

[0020] The electric contact pressure gauge 1 is installed on the gas pipeline inlet pipe 2. If the negative pressure in the gas pipeline inlet pipe 2 is lower than the set value of the electric contact pressure gauge 1 during the operation of the gas extraction system, the internal contact of the electric contact pressure gauge 1 will be connected, triggering the corresponding audible and visual alarm 3. After the audible and visual alarm 3 is triggered, the corresponding number 6 will light up synchronously. The ring 7 at the same time provides visual consistency between the audible and visual alarm 3 and the corresponding number 6, serving as a visual link. The duty personnel in the duty room can quickly observe the number 6 corresponding to the audible and visual alarm 3 and determine the corresponding gas pipeline inlet pipe 2 for handling.
