Description

Technical Field

[0001] The utility model relates to the technical field of fire safety, in particular to a centralized fire control system for large storage tank areas. Background Art

[0002] A large storage tank area usually refers to an area for storing high-risk chemicals, petroleum, natural gas and other liquids or gases, and effective fire protection needs to be carried out on this area. There are many related devices and corresponding fire pipelines in the existing storage tank area. At the same time, the number of control valves for controlling the above pipeline devices is large and relatively scattered. During fire control, multiple operators are required to rotate and open and close different valves, which takes a lot of time in this process, and it is impossible to ensure that the valves can be stably controlled, reducing the fire fighting efficiency and accuracy, and it is not convenient to carry out rapid centralized control and extinguishing in case of a fire.

[0003] In the prior art, a centralized power control of multiple valves is set through a control system, and the valves can be opened immediately when a fire breaks out so that the fire extinguishing materials are ejected. When the above control system is running, corresponding modules are established with the help of computer equipment. When the computer control equipment is used, and the outer screen is exposed, it is easy to be contaminated with a lot of dust, resulting in poor heat dissipation of the internal electronic components of the control equipment, thereby affecting the performance and stability of the equipment and reducing the efficiency of centralized fire control.

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0030] The embodiment of the present utility model discloses a fire control centralized control system for large storage tank areas.

[0031] Example 1

[0032] The utility model provides a centralized fire control system for a large storage tank area as shown in Figures 1-4 Figure 1, which includes a control host 1 and a control screen 2 arranged on the upper end of the control host 1. It is characterized in that a PLC controller 3 is fixedly arranged inside the control host 1, a plurality of control cables 4 are communicated and arranged on the side wall of the control host 1, a control valve 5 is communicated and arranged at the end of the control cable 4, and a heat sensor 6 is fixedly arranged on the outer wall of the control valve 5;

[0033] A sleeve plate 7 is fixedly sleeved on the lower end of the outer wall of the control host 1. A cavity is opened inside the sleeve plate 7. Rotating rods 8 are rotatably arranged at the lower ends of both sides inside the cavity. A winding wheel 9 is fixedly sleeved on the rod wall of the rotating rod 8. A first pulling rope 10 is fixedly arranged inside the winding wheel 9. Second pulling ropes 11 are arranged through elastic mechanisms on both sides inside the cavity. A plurality of through holes for the first pulling rope 10 and the second pulling rope 11 to pass through are opened at the top of the sleeve plate 7. The upper ends of the first pulling rope 10 and the second pulling rope 11 both pass through the sleeve plate 7 and a protective cloth 12 is fixedly arranged. A dust-proof net 22 is fixedly embedded inside the protective cloth 12. Two guiding plates 21 are fixedly arranged at both upper ends of both sides of the control host 1. The protective cloth 12 is in contact and cooperation with the guiding plates 21. The protective cloth 12 covers the outside of the control screen 2. Two symmetrically arranged support rods 13 are fixedly arranged at both upper ends of both sides of the control host 1. The protective cloth 12 covers the outside of the support rods 13. Limiting plates 20 are fixedly arranged on the outer walls of a plurality of support rods 13. The protective cloth 12 is arranged between a plurality of limiting plates 20.

[0034] When carrying out fire control on the storage tank area, a plurality of fire pipelines in the storage tank area are controlled through a plurality of switching valves 5. Through the connection between the control cable 4 and the control host 1, the control host 1 can centrally control a plurality of fire pipelines remotely. At the same time, with the arrangement of the heat sensor 6 and the PLC controller 3, the fire control work of the storage tank area can be carried out in a timely manner. When the control host 1 is in daily use, the protective cloth 12 is in contact with the outside of a plurality of support rods 13. At this time, the control screen 2 can be covered. And with the arrangement of the dust-proof net 22, it can prevent external dust from covering the outside of the control screen 2 and affecting the viewing clarity of the control screen 2, and reduce the heat dissipation effect of the internal electronic components of the control host 1, ensuring that the control host 1 can operate continuously and stably and improving the fire control accuracy;

[0035] When fire control work needs to be carried out, the rotating rod 8 can drive the winding wheel 9 to rotate, so that the first pulling rope 10 is wound. Through the arrangement of a plurality of support rods 13, the protective cloth 12 is separated from the control screen 2 by the pulling rope. At this time, the control screen 2 can be exposed for use without affecting the fire control work.

[0036] Example 2

[0037] Example 2 is based on Example 1. In order to drive the rotating rod 8 to rotate stably, the first pulling rope 1 is wound. As Figure 1 shown, a winding and separating mechanism for driving the protective cloth 12 away from the control screen 2 is provided on the rod wall of the rotating rod 8. The winding and separating mechanism includes an electric push rod 16. The electric push rod 16 is fixedly arranged at the lower end outside the sleeve plate 7, and the end of the output shaft penetrates into the cavity and is fixedly provided with a connecting plate 17. The connecting plate 17 is a U-shaped connecting plate. Rack bars 18 are fixedly arranged at both ends of the connecting plate 17. The rack bars 18 are engaged with a gear 19. The gear 19 is fixedly sleeved on the rotating rod 8. The heat sensor 6, the control valve 5, the control cable 4, the control host 1, the PLC controller 3 and the electric push rod 16 are electrically connected.

[0038] When the heat sensor 6 senses the appearance of high heat in the storage tank area, the PLC controller 3 controls the electric push rod 16 to start, so that the electric push rod 16 drives the connecting plate 17 to move. Supported by the connecting plate 17, the two rack bars 18 move simultaneously to drive the gear 19 to rotate. At this time, the gear 19 drives the rotating rod 8 to rotate, so that the winding wheel 9 starts the winding work, and the protective cloth 12 can be wound and separated from the control screen 2.

[0039] Example 3

[0040] Example 3 is based on Example 1. In order to ensure the setting stability of the protective cloth 12, as Figures 1-2 shown, the elastic mechanism includes a sliding rod 14. Sliding grooves are respectively opened on the inner walls of the cavity close to each other. The sliding rod 14 is slidably arranged in the sliding groove and is fixedly connected with the inner wall of the sliding groove through a spring 15. The bottom of the second pulling rope 11 is fixedly connected with the sliding rod 14.

[0041] In the daily state, through the engagement of the rack bar 18 and the gear 19, the position of the rotating rod 8 is determined at this time. Under the connection of the sliding rod 14 and the spring 15, the spring 15 elastically pulls the sliding rod 14. At this time, the second pulling rope 11 can be in a tensioned state. Through the connection of the protective cloth 12, the first pulling rope 11 is also in a tensioned state, so that the setting position of the protective cloth 12 can be fixed, and the control screen 2 can be stably covered and protected.

[0042] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
