Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing water bag filling technology, and in particular to a fire extinguishing water bag filling device for fire fighting. Background Technology

[0002] Fire extinguishing water bag filling is an important part of fire extinguishing preparation. Therefore, a fire extinguishing water bag filling device, with announcement number CN219728600U, is proposed. The inlet pipe is connected to an external water source. First, the fire extinguishing water bag is placed at one end of the base. Then, the threaded ring is pulled down to slide out the inner tube, so that the inner tube is inserted into the threaded pipe. At the same time, the operator rotates the threaded ring to connect the threaded ring and the threaded pipe together. The water pump sprays water into the inside of the fire extinguishing water bag through the inlet pipe, outer pipe, and inner pipe. It is not necessary to manually hold the inner tube with one hand and the threaded pipe with the other during filling.

[0003] The solution involves manually connecting the threaded ring to the threaded tube at the opening of the fire hose for filling. While this achieves a degree of automation, it requires manual connection of the threaded ring and the threaded tube, a process that demands skill and time. This can significantly reduce filling efficiency, especially when fire hoses are frequently replaced. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art, and to propose a fire extinguishing water bag filling device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire extinguishing water bag filling device, comprising a frame and a water bag, wherein a vertically arranged electric push rod is fixedly installed at the top of the frame, the telescopic end of the electric push rod faces downward and is fixedly installed with a water injection pipe, a connector is installed at the mouth of the water bag, the central axis of the connector is hollowed out and the upper and lower parts of the hollowed-out part are cylindrical and rectangular respectively, the bottom end of the water injection pipe is inserted into the upper hollowed-out part of the connector and extends to the lower part of the hollowed-out part of the connector, a sealing gasket is fixedly installed on the outer wall of the water injection pipe and overlaps with the top of the connector, and several spring rods are embedded in the top edge of the lower part of the hollowed-out part of the connector, the telescopic ends of the several spring rods face downward and are fixedly installed with sealing plugs that are inserted into the upper hollowed-out part of the connector.

[0006] Preferably, the water bag opening is fitted onto the outer side of the connector, and the outer side of the connector has an annular groove near the center, with a clamp engaged in the groove.

[0007] Preferably, the sealing plug is a T-shaped rotating body with a gap fit between the side of the sealing plug and the inner wall of the hollowed-out part of the connector, and the water outlet of the water injection pipe is located on the surface near the bottom.

[0008] Preferably, a horizontally arranged bidirectional lead screw is rotatably installed on the inner side of the frame, and a slider sleeved on the frame is threadedly connected to the threaded ends on both sides of the bidirectional lead screw. A connecting rod is fixedly installed on the same side of the two sliders, and the two connecting rods are slidably connected to the outer side of the connector, and the outer side of the connector extends outward in a ring shape and overlaps the upper surface of the two connecting rods.

[0009] Preferably, the two connecting rods are fitted with retaining frames, and hollow frames fixed on the machine frame are inserted into the two ends of the retaining frames. A pin is provided through the retaining frame to be inserted into the hollow part of the hollow frame.

[0010] Preferably, a support frame is rotatably connected between the hollow frame and the bottom surface of the frame, and the two support frames are respectively located at the free ends of the two connecting rods, with the free ends of the connecting rods overlapping the top edges of the support frames at adjacent positions.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a spring rod, when the water injection pipe is inserted into the connector 13, its bottom end will push the sealing plug to overcome the tension of the spring rod and descend to the lower part of the connector's hollow part. That is, the gap between the sealing plug and the lower part of the connector's hollow part allows the water sprayed from the water injection pipe to enter the water bag. Conversely, when the water injection pipe rises and disengages from the connector, the elastic contraction of the spring rod can automatically make the sealing plug rise and seal the upper part of the connector's hollow part, thus achieving a seal to prevent water leakage. The whole process does not require manual operation, is simple and quick, and ensures filling efficiency.

[0014] 2. In this utility model, the distance between the two sliders can be adjusted to facilitate the adjustment of the distance between the two connecting rods, thereby making it easy to make adaptive adjustments according to the size of the connector used, so as to achieve a smooth connection of the connector. The position of the baffle can be adjusted according to the diameter of the connector to ensure that when an empty water bag is installed, the connector slides on the upper surface of the two connecting rods until the baffle touches the connector, and the connector is located directly below the water injection pipe, which facilitates the positioning of the connector.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4As shown, a fire extinguishing water bag filling device includes a frame 1 and a water bag 2. A vertically mounted electric push rod 8 is fixedly installed at the top of the frame 1. The telescopic end of the electric push rod 8 faces downwards and is fixedly mounted with a water injection pipe 11. The top of the water injection pipe 11 is connected to an existing water pump (not shown in the figure), which draws fire-fighting water into the water injection pipe 11 and sprays it out along the pipe. A connector 13 is installed at the mouth of the water bag 2, which overlaps and is fixedly positioned on the frame 1. The connector 13 has a through-hole at its central axis, with the upper and lower parts of the through-hole being cylindrical and rectangular, respectively. The bottom end of the water injection pipe 11 is inserted into the upper through-hole of the connector 13 and extends to the lower part of the through-hole. A sealing gasket 12 is fixedly installed on the outer wall of the water injection pipe 11, overlapping the top of the connector 13. The extension of the electric push rod 8 lowers the water injection pipe 11 to the surface of the connector 13, until the sealing gasket 12 is reached on the surface of the water injection pipe 11. A seal is achieved by tightly fitting the top of the connector 13. Several spring rods 16 are embedded in the top edge of the lower part of the hollow section of the connector 13. The telescopic ends of the spring rods 16 face downward and are fixedly installed with sealing plugs 15 that are inserted into the upper part of the hollow section of the connector 13. The sealing plugs 15 are T-shaped rotating bodies with a gap fit between the side of the sealing plugs 15 and the inner wall of the lower part of the hollow section of the connector 13. The water outlet of the water injection pipe 11 is located near the bottom of the surface. When the water injection pipe 11 is inserted into the connector 13, its bottom end will push the sealing plug 15 to overcome the tension of the spring rods 16 and descend to the lower part of the hollow section of the connector 13. That is, the gap between the sealing plug 15 and the lower part of the hollow section of the connector 13 allows the water sprayed from the water injection pipe 11 to enter the water bag 2. Conversely, when the water injection pipe 11 rises and disengages from the connector 13, the elastic contraction of the spring rods 16 can automatically make the sealing plug 15 rise and seal the upper part of the hollow section of the connector 13, thus achieving a seal and preventing water leakage.

[0023] To facilitate the installation of connector 13 and water bag 2: the opening of water bag 2 is fitted onto the outer side of connector 13. Near the center of the outer side of connector 13, there is an annular groove with a clamp 14. The clamp 14 can be used to tightly bind and fix the opening of water bag 2 to the groove on the surface of connector 13.

[0024] A horizontally mounted bidirectional lead screw 3 is rotatably installed on the inner side of the frame 1. Slider blocks 4, fitted onto the frame 1, are threaded onto both sides of the bidirectional lead screw 3. Rotation of the bidirectional lead screw 3 allows the two sliders 4 to move relative to or towards each other to adjust their spacing. Connecting rods 9 are fixedly installed on the same side of each slider 4. The two connecting rods 9 are slidably connected to the outer side of the connector 13, with the outer side of the connector 13 extending outward in a ring shape and overlapping the upper surface of the two connecting rods 9. Adjusting the spacing between the two sliders 4 facilitates adjustment of the spacing between the two connecting rods 9, allowing for adaptive adjustment according to the size of the connector 13 used, and ensuring smooth overlap of the connector 13. A retaining frame 6 is fitted onto each of the two connecting rods 9. A perforated frame 5, fixed to the frame 1, is inserted into both ends of the retaining frame 6. A pin 7, inserted into the perforated portion of the perforated frame 5, passes through the retaining frame 6. The frame 6 is located between the connector 13 and the bidirectional lead screw 3, and the side of the frame 6 abuts against the annular protrusion on the outside of the connector 13. The pin 7 connects the frame 6 to the cutouts at different positions on the cutout frame 5 to facilitate the adjustment of the position of the frame 6. This allows the position of the frame 6 to be adjusted according to the diameter of the connector 13, ensuring that when the empty water bag 2 is installed, the connector 13 slides on the upper surface of the two connecting rods 9 until the frame 6 abuts, at which point the connector 13 is positioned directly below the water injection pipe 11. A support frame 10 is rotatably connected between the cutout frame 5 and the bottom surface of the frame 1. The two support frames 10 are located at the free ends of the two connecting rods 9, and the free ends of the connecting rods 9 overlap with the top edges of the adjacent support frames 10. By rotating the two support frames 10 to the bottom edge of the corresponding connecting rod 9 end, the bending and deformation of the connecting rod 9 due to the weight of the water bag 2 during water injection can be prevented.

[0025] Working principle: Based on the size of the connector 13 at the mouth of the water bag 2, the distance between the two connecting rods 9 is adjusted by rotating the two-way screw 3, and the position of the baffle 6 is adjusted again according to the size of the connector 13. The connector 13 is stuck between the two connecting rods 9 and slides along the upper surface of the connecting rods 9 until it contacts the surface of the baffle 6. Then, the electric push rod 8 extends to lower the water injection pipe 11 to the surface of the connector 13. When the water injection pipe 11 is inserted into the connector 13, its bottom end will push the sealing plug 15 to overcome the tension of the spring rod 16 and descend to the lower part of the hollow part of the connector 13. That is, the gap between the sealing plug 15 and the lower part of the hollow part of the connector 13 allows the water sprayed from the water injection pipe 11 to enter the water bag 2.

[0026] The wiring diagram of the electric push rod 8 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric push rod 8 will not be explained in detail.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or equivalent variations to the above-disclosed technical content and apply them to other fields. However, any simple modifications, equivalent variations and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
