[0018] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] Refer to the attached Figure 1-3 The utility model proposes a fire water tank with water inlet buffering and noise reduction function, including a water tank body 10, and a first drain pipe 11 is installed at the bottom of the side wall of the water tank body 10; wherein a valve is provided on the first drain pipe 11 for controlling the opening and closing of the internal channel of the first drain pipe 11.

[0021] A buffer water tank 20 is fixedly installed at the top position of the side wall of the water tank body 10, and a second drain pipe 27 is installed on the bottom wall of the buffer water tank 20 (a valve is also installed on the second drain pipe 27); wherein the buffer water tank 20 is installed on the outer wall of the water tank body 10 in a ring shape.

[0022] An inlet pipe 21 is installed on the side wall of the buffer water tank 20; wherein, the inlet pipe 21 is arranged at an angle, that is, the water outlet of the inlet pipe 21 is at the lowest point, thus preventing impurities from flowing back into the water storage pump equipment through the inlet pipe 21.

[0023] A plurality of through holes 25 are provided at the top of the inner wall of the buffer water tank 20, and the through holes 25 are connected to the interior of the water tank body 10; wherein, the plurality of through holes 25 are provided in an array with the central axis of the water tank body 10 as a reference line. The purpose of providing the plurality of through holes 25 here is to speed up the outflow of water inside the buffer water tank 20, thereby saving time for filling the water tank body 10.

[0024] An arc-shaped baffle 26 is fixedly installed on the inner wall of the water tank body 10, and the arc-shaped baffle 26 is used to guide the water flowing out of the through hole 25 to the side wall of the water tank body 10; wherein, the bottom edge of the arc-shaped baffle 26 does not contact the inner wall of the water tank body 10, and the arc-shaped baffle 26 itself is arranged in an arc-shaped state, so that the water entering the arc-shaped baffle 26 can be guided to the inner wall of the water tank body 10 along the arc-shaped side wall of the arc-shaped baffle 26, so that the water is injected into the interior of the water tank body 10 along the side wall of the water tank body 10, thereby reducing the noise problem generated by the water flow.

[0025] A filter screen 30 is detachably installed inside the buffer water tank 20 , and the filter screen 30 is used to filter impurities in the water; wherein the filter screen 30 is also arranged in a ring shape.

[0026] The inner wall of the buffer water tank 20 is provided with a slot 22, and the filter screen 30 is placed on the inner bottom wall of the slot 22; wherein, after the slot 22 is provided on the inner wall of the buffer water tank 20, an installation groove is formed on the inner wall of the buffer water tank 20, and the outer wall of the filter screen 30 can be placed in the installation groove, so that the filter screen 30 can block impurities in the water to a certain extent and prevent the impurities from blocking the through hole 25.

[0027] The top wall of the buffer water tank 20 is installed with a cover plate 23 by bolts, and a pressure rod 24 is fixedly installed on the bottom wall of the cover plate 23, and the pressure rod 24 presses on the outer wall of the filter screen 30; wherein, a sealing gasket is provided at the outer edge of the cover plate 23, so that after the cover plate 23 is installed on the top of the buffer water tank 20, the water in the buffer water tank 20 can be prevented from flowing out. In addition, a pressure rod 24 is provided on the cover plate 23, and when the cover plate 23 is installed, the pressure rod 24 can press on the outer wall of the filter screen 30, thereby improving the stability of the installation of the filter screen 30; at the same time, through the set cover plate 23, the filter screen 30 can be disassembled and replaced, and the impurities on the bottom wall inside the buffer water tank 20 can also be cleaned up by removing the filter screen 30 at a later stage.

[0028] In this embodiment, the working principle of the device is as follows: when water is stored inside the water tank body 10, the water in the water inlet pipe 21 enters the buffer water tank 20 in advance. As the water source continues to flow into the buffer water tank 20, the water level inside the buffer water tank 20 rises. When the water level reaches the position of the through hole 25, the water in the buffer water tank 20 overflows into the interior of the water tank body 10 through the through hole 25. Under the blocking effect of the arc-shaped baffle 26, the water flows into the inner wall of the water tank body 10, and then is injected into the water tank body 10 along the inner wall of the water tank body 10, thereby reducing the noise caused by the water flow, reducing the interference of the water flow sound to residents, and improving the practicality of the device.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
