The mounting seat side wall has a baffle inclined downward and outward. The mounting seat has a notch on its lower surface. The stirring rod is rotatably connected in the notch. The length of the stirring rod is equal to one third to one half of the length of the stirring shaft.

[0006] Furthermore, the length of the stirring rod is one third of the length of the stirring shaft, the number of the mounting seats is two, and the two mounting seats are arranged at an interval up and down.

[0007] Furthermore, the stirring shaft is also provided with an impeller, and the impeller is located above the mounting seat.

[0008] Furthermore, the impeller is fixedly connected to the mounting seat by bolts.

[0009] Furthermore, an ultrasonic detector is installed below the second storage tank.

[0010] Furthermore, a probe is installed below the first storage tank, and the probe extends into the first storage tank.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the second storage tank of the utility model, a mounting seat is installed on the circumferential surface of the stirring shaft, a notch is provided on the lower surface of the mounting seat, a baffle is provided on the side wall of the mounting seat, and the stirring rod is rotatably connected in the notch. When the stirring shaft starts to rotate, the stirring rod starts to swing outward under the action of centrifugal force until the side wall of the stirring rod hits the baffle. Then, the arrangement can greatly increase the stirring range and the stirring rod will not hit the inner wall of the second storage tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0017] like Figure 1-Figure 2 As shown, this embodiment provides a pump-type agent suppression fire extinguishing device, including a first storage tank 1 and a second storage tank 2.

[0018] The first storage tank 1 and the second storage tank 2 are connected to the input end of the pump assembly through a first pipeline, and a control valve assembly is provided on the first pipeline; the first storage tank 1 is filled with fire extinguishing inhibitor, and a probe is installed below the first storage tank 1, and the probe extends into the first storage tank 1. The second storage tank 2 is filled with water-based fire extinguishing agent, and an ultrasonic detector is installed below the second storage tank 2.

[0019] The second storage tank 2 is provided with a stirring shaft 21 and a stirring rod 23. The stirring shaft 21 has a mounting seat 22 on its circumference. The side wall of the mounting seat 22 has a baffle 221 that is tilted downward and outward. The lower surface of the mounting seat 22 has a notch, and the number of notches is 2-3. The stirring rod 23 is rotatably connected in the notch. The length of the stirring rod 23 is equal to one-third to one-half of the length of the stirring shaft 21. In this solution, the length of the stirring rod 23 is one-third of the length of the stirring shaft 21. There are two mounting seats 22, and the two mounting seats 22 are arranged at intervals up and down. The stirring shaft 21 is also provided with an impeller 24, which is located above the mounting seat 22. The impeller 24 is fixedly connected to the mounting seat 22 by bolts. By providing the impeller 24, the impeller 24 and the stirring rod 23 can be synchronously double stirred to improve the stirring efficiency.

[0020] In the second storage tank 2 of the present scheme, a mounting seat 22 is installed on the circumference of the stirring shaft 21, and a notch is provided on the lower surface of the mounting seat 22. A baffle 221 is provided on the side wall of the mounting seat 22, and the stirring rod 23 is rotatably connected in the notch. When the stirring shaft 21 starts to rotate, the stirring rod 23 starts to swing outward under the action of centrifugal force until the side wall of the stirring rod 23 hits the baffle 221. Then, the setting can greatly increase the stirring range and the stirring rod 23 will not hit the inner wall of the second storage tank 2.
