Detailed Implementation
[0026] To facilitate understanding of this utility model, a more comprehensive description of this application will be given below with reference to the accompanying drawings, which show preferred embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.
[0027] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0029] like Figures 1 to 4 As shown, this application provides a foam spray fire extinguishing device, including a mobile frame 100 and a foam storage tank 110. The foam storage tank 110 is fixed on the mobile frame 100, which is used to move the foam storage tank 110. A drain pipe 150 is fixed at the bottom of the foam storage tank 110 to facilitate the discharge of cleaning liquid during cleaning. A foam proportioner 120 is fixed on the foam storage tank 110. The foam proportioner 120 uses the principle of the Venturi tube to form a negative pressure in the mixing chamber. Under the action of atmospheric pressure, the foam liquid in the foam storage tank 110 is drawn into the Venturi tube and mixed with water to achieve proportioning. The foam storage tank 110 is composed of a cylinder and two hemispheres. The two hemispheres are respectively fixed at both ends of the cylinder, and the foam storage tank 110 is a hollow tank.
[0030] A cleaning plate 160 is positioned inside the foam storage tank 110. The cleaning plate 160 consists of an arc-shaped plate and two hemispherical arc-shaped plates. One hemispherical arc-shaped plate is fixed to the end face of the arc-shaped plate. The arc-shaped plate abuts against the inner wall surface of the foam storage tank 110, and the hemispherical arc-shaped plate abuts against the inner wall surfaces at both ends of the foam storage tank 110.
[0031] A fixing rod 161 is fixed to the side of the cleaning plate 160. The fixing rod 161 extends out of the foam storage tank 110, and a turntable 162 is fixed to the extended end of the fixing rod 161. The connection between the fixing rod 161 and the foam storage tank 110 is rotatably sealed.
[0032] It is worth noting that the cleaning plate 160 can fit closely to the internal shape of the foam storage tank 110. When cleaning the foam storage tank 110, rotating the turntable 162 can drive the fixing rod 161 to rotate at the foam storage tank 110, thereby causing the cleaning plate 160 to rotate along the inner wall of the foam storage tank 110, scraping away impurities on the inner wall of the foam storage tank 110, and better cleaning the dead corners of the foam storage tank 110.
[0033] Specifically, such as Figures 3 to 6 As shown, an arc-shaped gas soft bag 164 is fixed to the outside of the cleaning plate 160. A silicone brush 166 is fixed to the outside of the gas soft bag 164 near the inner wall of the foam storage tank 110. The silicone brush 166 does not easily adsorb foam and can clean the inner wall of the foam storage tank 110. The silicone brush 166 is in contact with the inner wall of the foam storage tank 110.
[0034] As is easily understood, the silicone brush 166 increases the contact force with the inner wall of the foam storage tank 110, enabling better cleaning of the inner wall of the foam storage tank 110.
[0035] Specifically, such as Figures 3 to 6 As shown, a vent pipe 163 is fixed on the foam storage tank 110. One end of the vent pipe 163 is connected to an air pump, which is fixed on the foam storage tank 110. One end of the vent pipe 163 passes through a fixing rod 161 and extends into the gas soft bag 164. The fixing rod 161 and the vent pipe 163 are not connected to each other, and the rotation of the fixing rod 161 does not affect the air intake of the vent pipe 163. The connection between the vent pipe 163 and the gas soft bag 164 is airtight and fixed.
[0036] As is easily understood, by inflating the air tube 163 with an air pump, the gas soft bag 164 expands, causing the silicone brush 166 to press against the foam storage tank 110, further increasing the contact force between the silicone brush 166 and the foam storage tank 110, making it easier to clean stubborn impurities from the inner wall of the foam storage tank 110.
[0037] Specifically, such as Figure 5 and Figure 6 As shown, a liquid soft capsule 165 is fixed to the outside of the gas soft capsule 164. The liquid soft capsule 165 is filled with two-thirds liquid. A silicone brush 166 is fixed to the liquid soft capsule 165.
[0038] It is worth noting that when the cleaning plate 160 moves on the inner wall of the foam storage tank 110, the liquid in the liquid soft bag 165 will shake during the movement, thereby causing the silicone brush 166 to vibrate and clean as it moves on the inner wall of the foam storage tank 110.
[0039] In the above embodiment, when cleaning the inside of the foam storage tank 110, the gas soft bag 164 is inflated through the vent pipe 163, causing the gas soft bag 164 to expand and drive the silicone brush 166 to contact the inner wall of the foam storage tank 110. Then, the turntable 162 is rotated to drive the fixed rod 161 to rotate, so that the cleaning plate 160 rotates and cleans inside the foam storage tank 110. By repeatedly inflating and deflating the gas soft bag 164, the contact force between the silicone brush 166 and the foam storage tank 110 is increased, improving the cleaning effect and thoroughly cleaning the inside of the foam storage tank 110 to ensure safety for the next use.
[0040] Specifically, such as Figures 1 to 8 As shown, a push plate 130 is fixed on the mobile frame 100. The push plate 130 facilitates the user to push the mobile frame 100 and move the foam storage tank 110. A winding part 140 is fixed on the push plate 130, which is used to wind up the water hose.
[0041] Specifically, such as Figure 7 and Figure 8 As shown, the winding section 140 includes a movable shaft 141;
[0042] The push plate 130 is a hollow rectangular frame, and the movable shaft 141 is rotatably connected within the installation space of the push plate 130.
[0043] A mounting frame 142 is fixed on the movable shaft 141. The mounting frame 142 is a U-shaped frame and a take-up roller 143 is rotatably connected to its opening.
[0044] Specifically, such as Figure 7 and Figure 8 As shown, the mounting frame 142 and the push plate 130 are positioned by a rod 144. The push plate 130 has a slot 131, and the mounting frame 142 has a through groove on its side. One end of the rod 144 is inserted into the slot 131, and the other end of the rod 144 is inserted into the through groove of the mounting frame 142.
[0045] This means that the mounting frame 142 and the push plate 130 are positioned by the insertion rod 144 to prevent the mounting frame 142 from flipping over and to facilitate the winding of the water hose.
[0046] In the above embodiments, when winding the water hose, the mounting frame 142 is flipped outward, and the mounting frame 142 is positioned by the insert rod 144 to prevent the winding roller 143 from shifting. The water hose is wound around the winding roller 143, and the water hose is wound up by rotating the winding roller 143. This avoids the water hose from getting tangled, which would increase the time for fire rescue, and also avoids the water hose from getting tangled and causing the bending part to break, thus ensuring the safety of use.
[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
