Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing agent filling technology, specifically a valve-type fire extinguishing agent filling structure. Background Technology

[0002] Fire extinguishing agent filling refers to the process of adding or replacing the fire extinguishing agent stored in a fire extinguisher to ensure that the fire extinguisher can function properly in an emergency.

[0003] For example, the Chinese authorized patent with announcement number CN206858121U (A water-based fire extinguisher filling production line with automatic valve tightening) includes: support legs, production line, filling cabinet, automatic valve tightening cabinet, water-based fire extinguishing agent tank, photoelectric electronic eye, laser detector, mechanical wrench, positioning electronic eye, filling fixture, air filling pipe, exhaust valve, and filling interface. Support legs are set at the bottom of the production line. The automatic valve tightening cabinet and filling cabinet are arranged sequentially on the production line. The water-based fire extinguishing agent tank is located on the right side of the production line. The photoelectric electronic eye, laser detector, and mechanical wrench are all located inside the automatic valve tightening cabinet. The positioning electronic eye, filling fixture, and filling interface are all installed on the automatic filling cabinet. The filling interface is connected to the water-based fire extinguishing agent tank through the air filling pipe. An exhaust valve is set on the air filling pipe.

[0004] However, most existing fire extinguishing agent filling tanks have their discharge ports facing downwards and sealed by valves. The angle is not adjustable, and when the valves age or are damaged by collisions, the discharge ports will continuously discharge, resulting in waste of fire extinguishing agent. Therefore, this does not meet the current requirements. To address this, we propose a valve-type fire extinguishing agent filling structure. Utility Model Content

[0005] The purpose of this utility model is to provide a valve-type fire extinguishing agent filling structure to solve the problem mentioned in the background art that most of the existing fire extinguishing agent filling tanks have their discharge ports facing downwards and sealed by valves with non-adjustable angles. When the valves age or are damaged by collisions, the discharge ports will continue to discharge, resulting in waste of fire extinguishing agents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a valve-type fire extinguishing agent filling structure, comprising: a support frame and a filling tank, wherein the support frame is located outside the filling tank, a base is welded to the front surface of the bottom end of the support frame, a connecting sleeve is welded to the center of both ends of the filling tank, a rotating shaft is inserted into one end of the connecting sleeve, a ball bearing is provided at one end of the rotating shaft, a rotating groove is provided on both sides of the support frame, and the ball bearing is embedded in the rotating groove, and the rotating shaft is rotatably connected to the support frame through the ball bearing, and a stabilizing component is provided at the center of the front surface of the filling tank.

[0007] Preferably, both the connecting sleeve and the rotating shaft have mounting holes on one side surface, and the mounting holes penetrate the connecting sleeve and the rotating shaft. A fastener is inserted into the mounting hole, and one end of the fastener is connected to a nut.

[0008] Preferably, the stabilizing component includes a stabilizing baffle, with stabilizing side plates provided on both sides of one end of the stabilizing baffle. A first insertion hole is provided at the center of the upper surface of the stabilizing side plate, and a second insertion hole is provided on the upper surface of the support frame. A U-shaped pin is inserted into one end of the second insertion hole, and the insertion end of the U-shaped pin passes through the first insertion hole and is inserted into the interior of the second insertion hole. A stabilizing notch is provided on the front surface of the top of the support frame for inserting the stabilizing baffle.

[0009] Preferably, the stabilizing component further includes a fixing plate, which is located on both sides of the other end of the stabilizing baffle and is fixed to the filling tank by external bolts.

[0010] Preferably, a limit baffle is provided on the upper surface of the filling tank near the rear end, a feed pipe is provided on the upper surface of the filling tank near the front end, a discharge pipe is provided on the front surface of the filling tank near the bottom end, and a solenoid valve is provided at one end of the discharge pipe.

[0011] Preferably, a mounting groove is provided at the center of the upper surface of the base, and the front surface of the base has a heat dissipation vent that communicates with the mounting groove.

[0012] Preferably, the mounting slot is provided with an electric push rod, and the output end of the electric push rod is provided with a placement platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model changes the position of the discharge pipe by rotating the filling tank. During normal filling, the discharge port of the discharge pipe faces downward and the opening of the feed pipe faces upward. The limiting baffle contacts the support frame, keeping the filling tank horizontal and not rotating. After filling, the filling tank is rotated clockwise, and the stabilizing baffle rotates into the stabilizing notch. It is reinforced by the U-shaped pin to prevent the filling tank from rotating back. At this time, the discharge pipe is located at the upper end and does not contact the fire extinguishing agent stored inside the filling tank. When the solenoid valve ages or is damaged by collision, there will be no leakage and waste of fire extinguishing agent. This solves the problem that most of the discharge ports of existing fire extinguishing agent filling tanks face downward and are sealed by valves. The angle is not adjustable. When the valve ages or is damaged by collision, the discharge port will continue to discharge, resulting in waste of fire extinguishing agent.

[0015] (2) By installing an electric push rod inside the installation slot, the fire extinguisher canister is placed on the placement platform. The electric push rod drives the placement platform to move up, so that the discharge pipe is inserted into the filling port of the fire extinguisher canister. This avoids the phenomenon of fire extinguishing agent being contaminated and spilled due to the gap between the discharge pipe and the fire extinguisher canister during discharge, thereby improving filling safety and reducing waste.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a valve-type fire extinguishing agent filling structure, comprising: a support frame 1 and a filling tank 2, wherein the support frame 1 is located outside the filling tank 2, a base 3 is welded to the front surface of the bottom end of the support frame 1, and a connecting sleeve 18 is welded to the center of both ends of the filling tank 2, a rotating shaft 6 is inserted into one end of the connecting sleeve 18, a ball bearing 5 is provided at one end of the rotating shaft 6, a rotating groove 4 is provided on both sides of the support frame 1, and the ball bearing 5 is embedded in the rotating groove 4, and the rotating shaft 6 is rotatably connected to the support frame 1 through the ball bearing 5, and a mounting hole 19 is provided on one side of both the connecting sleeve 18 and the rotating shaft 6, and the mounting hole 19 passes through the connecting sleeve 18 and the rotating shaft 6, a fastener 20 is inserted into the mounting hole 19, and a nut is externally connected to one end of the fastener 20, and the fastener is fixed by threaded connection of the nut after passing through the mounting hole 19, thereby realizing the connection of the support frame 18 and the rotating shaft 6. 8 is fixed to the rotating shaft 6. When the rotating shaft 6 rotates, the connecting sleeve 18 will rotate, which will drive the filling tank 2 to rotate. A stabilizing component 24 is provided at the center of the front surface of the filling tank 2. A limit baffle 15 is provided on the upper surface of the filling tank 2 near the rear end. A feed pipe 17 is provided on the upper surface of the filling tank 2 near the front end. A discharge pipe 10 is provided on the front surface of the filling tank 2 near the bottom end. A solenoid valve 11 is provided at one end of the discharge pipe 10. Under normal conditions, the discharge port of the discharge pipe 10 of the filling tank 2 faces downward and the opening of the feed pipe 17 faces upward. Since the stabilizing component 24 is heavier than the limit baffle 15, it will drive the filling tank 2 to rotate counterclockwise. At this time, the limit baffle 15 contacts the support frame 1, so that the filling tank 2 remains horizontal and does not rotate. The extinguishing agent is delivered into the filling tank 2 for storage through the feed pipe 17. The feed pipe 17 is used to install a sealing cap (not shown in the figure) for sealing.

[0023] The stabilizing component 24 includes a stabilizing baffle 7. Stabilizing side plates 8 are provided on both sides of one end of the stabilizing baffle 7. A first insertion hole 9 is provided at the center of the upper surface of the stabilizing side plate 8. A second insertion hole 13 is provided on the upper surface of the support frame 1. A U-shaped pin 14 is inserted into one end of the second insertion hole 13, and the insertion end of the U-shaped pin 14 passes through the first insertion hole 9 and then inserts into the second insertion hole 13. A stabilizing notch 12 is provided on the front surface of the top of the support frame 1 for inserting the stabilizing baffle 7. A mounting groove is provided at the center of the upper surface of the base 3. 21, and the front surface of the base 3 has a heat dissipation vent that communicates with the mounting groove 21. An electric push rod 23 is installed inside the mounting groove 21. The output end of the electric push rod 23 is provided with a placement platform 22. The heat dissipation vent facilitates the heat dissipation of the electric push rod 23. During filling, the fire extinguisher canister is placed on the placement platform 22. The electric push rod 23 drives the placement platform 22 to move upward, so that the discharge pipe 10 is inserted into the filling port of the fire extinguisher canister. The filling of the extinguishing agent is controlled by the solenoid valve 11. The fire extinguisher canister with the filling port is an existing device.

[0024] After filling, the electric push rod 23 moves the placement platform 22 down to its initial position, separating the discharge pipe 10 from the fire extinguisher tank. The filling tank 2 rotates clockwise, causing the stabilizing baffle 7 to rotate into the stabilizing notch 12, thus limiting rotation and preventing further rotation of the filling tank 2. The U-shaped pin 14, through the first insertion hole 9, is inserted into the second insertion hole 13, fixing the stabilizing baffle 7 and preventing the filling tank 2 from rotating backward. At this point, the discharge pipe 10 is at the upper end and does not contact the extinguishing agent stored inside the filling tank 2. Figure 2 As shown, when the solenoid valve 11 ages or is damaged by collision, there will be no leakage or waste of extinguishing agent.

[0025] Furthermore, the stabilizing assembly 24 also includes a fixing plate 16, which is located on both sides of the other end of the stabilizing baffle 7. The fixing plate 16 is fixed to the filling tank 2 by external bolts, which facilitates the disassembly and replacement of the stabilizing assembly 24.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
