[0002] Fire pumps refer to special fire pumps or ordinary clean water pumps that meet the national standard "Fire Pump Performance Requirements and Test Methods" GB6245. Most fire water sources provide fire water that needs to be pressurized by fire pumps to meet the requirements for water pressure and water volume during fire fighting.

[0003] Since fire pumps are only used in the event of a fire or accident, they are usually kept in a closed state for a long time. In actual use, the pump will not be started for a long time, causing its internal rotating structure to rust and jam. As a result, the fire pump cannot work normally when it is needed in a fire or accident. Therefore, under normal circumstances, the fire pump needs to be used regularly. The use of the fire pump not only wastes water resources but also requires a lot of labor costs to operate. Utility Model Content

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] Example: See Figure 1-3 The utility model provides a technical solution: based on the modified structure of a fire pump for a building, it includes a fire pump body 1, the two ends of the fire pump body 1 are respectively connected with an inlet pipe 2 and an outlet pipe 4, the sides of the inlet pipe 2 and the outlet pipe 4 are respectively connected with an outlet pipe 3 and an inlet pipe 5, the side of the fire pump body 1 is connected with a shell 6, and the shell 6 is connected with an air pressure component 8 and a filter component 7, which are used to form an air circulation in the fire pump body 1;

[0022] Furthermore, the filter component 7 includes a filter shell 701, an air flow baffle 702 is obliquely connected to the filter shell 701, a magnet 703 is connected to the filter shell 701, an air intake pipe 5 is connected to the side of the filter shell 701, and the other end of the filter shell 701 is connected to the side of the pneumatic component 8. The circulating airflow can be filtered through the filter shell 701, and the iron filings in the airflow can be adsorbed through the structure of the magnet 703, thereby avoiding the iron filings from affecting the transmission structure inside the fire pump.

[0023] The pneumatic component 8 includes a connecting shell 801, a pneumatic shell 802 is connected to the top of the connecting shell 801, an electric telescopic rod 803 is connected to the top of the pneumatic shell 802, a pneumatic plate is provided at the bottom of the electric telescopic rod 803, the pneumatic plate is slidably connected to the inner wall of the pneumatic shell 802, two one-way valves 804 are connected inside the connecting shell 801, the two one-way valves 804 are respectively arranged on both sides of the pneumatic shell 802, the communication directions of the two one-way valves 804 are both toward the direction of the outlet pipe 3, a pressure sensor 805 is connected inside the connecting shell 801, which is used to ensure that the airflow inside the device flows in a single direction, and the side of the connecting shell 801 away from the filter component 7 is connected to the air inlet pipe 5;

[0024] Furthermore, the one-way valve 804 includes a rotating blocking plate and a limiting plate. The limiting plate is connected to the inner wall of the connecting shell 801, and the rotating blocking plate is rotatably connected to the connecting shell 801. The rotating blocking plate is in contact with the limiting plate. The two one-way valves 804 can ensure that the airflow inside the device flows in one direction, so that a circulating one-way airflow is formed under the drive of the lifting and sliding of the air pressure plate driven by the electric telescopic rod 803, ensuring the effect of the device in driving the internal rotation of the fire pump.

[0025] The water inlet pipe 2 and the water outlet pipe 4 are provided with control valves, the air outlet pipe 3 and the air inlet pipe 5 are provided with control valves, the water inlet pipe 2 and the water outlet pipe 4 are provided with three-way pipes, and the water inlet pipe 2 and the water outlet pipe 4 are connected with the air outlet pipe 3 and the air inlet pipe 5 through the three-way pipes.

[0026] An adhesive layer is provided on the surface of the airflow baffle 702 , and a plurality of airflow baffles 702 are arranged at equal intervals and tilted inside the filter housing 701 , and the magnet 703 is arranged between the plurality of airflow baffles 702 .

[0027] The device can be conveniently installed and fixed on the outside of an existing fire water pump, thereby reducing the difficulty of installing the device and making the device effectively compatible with the existing fire water pump structure.

[0028] When the device is in working state, the connection combination structure of the device can be realized by installing a three-way pipe on the water inlet pipe 2 and the water outlet pipe 4, and an air circuit inside the fire water pump can be formed through the air outlet pipe 3 and the air inlet pipe 5.

[0029] When the control valves on the water inlet pipe 2 and the water outlet pipe 4 are in a closed state, the control valves on the air outlet pipe 3 and the air inlet pipe 5 are opened to ensure smooth circulation of the airflow.

[0030] When the air outlet pipe 3 and the air inlet pipe 5 are in an open state, the electric telescopic rod 803 is turned on. When the electric telescopic rod 803 drives the air pressure plate to slide upward, the one-way valve 804 close to one side of the air outlet pipe 3 is in close contact with the limit plate, thereby preventing the air flow from passing through. The one-way valve 804 on the other side rotates the blocking plate counterclockwise under the drive of the reduced air pressure inside the air pressure shell 802, thereby achieving the effect of air intake from one end of the air outlet pipe 3 of the device. When the air pressure plate slides downward under the drive of the electric telescopic rod 803, the air inside the connecting shell 801 is squeezed, so that the one-way valve 804 close to one side of the air outlet pipe 3 is in close contact with the limit plate, thereby preventing the air flow from flowing back and ensuring that the squeezed air flow is discharged from the air outlet pipe 3, thereby achieving the one-way airflow effect of the device.

[0031] During the process of squeezing air by the device, the air pressure inside the current connection shell 801 can be detected in real time through the pressure sensor 805. When the fire water pump rotates under the drive of the airflow, the air pressure inside the connection shell 801 gradually decreases as the fan blades inside the water pump rotate, thereby reaching a balanced air pressure. When the air pressure inside the connection shell 801 continues to rise, it can be determined that the current fire water pump is in a stuck state and needs manual maintenance.

[0032] When the fire pump is not in a stuck state, the reciprocating sliding of the electric telescopic rod 803 can form a continuous unidirectional airflow inside the shell 6, and the circulating airflow can clean the inside of the water pump. When the airflow passes through the inside of the filter shell 701, the airflow can be blocked by the airflow baffle 702. Dust particles will be adhered by the adhesion layer on the surface of the airflow baffle 702, reducing the dust inside the water pump. At the same time, iron filings generated by wear in the water pump will be adsorbed on the magnet 703, thereby avoiding continuous wear inside the water pump.

[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0034] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
