[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 In this embodiment, an adjustable fire extinguishing agent filling and discharging device includes a transport vehicle 1 and a fire truck 2, and the transport vehicle 1 is provided with a filling and discharging mechanism.

[0023] In this embodiment, the filling and discharging mechanism includes a feed pipe 3 fixedly installed on the top of the fire truck 2. A protective shell 4 is provided on the transport vehicle 1. The protective shell 4 is made of a double-layer board, and the inside of the double-layer board is filled with sound-absorbing cotton. It is convenient to reduce the noise caused by the operation of the machine through the sound-absorbing cotton, thereby reducing environmental noise. An inspection door is hinged on the front of the protective shell 4, and the inspection door is located at the lower left of the protective shell 4, which is convenient for the staff to inspect and maintain the various structural equipment on the transport vehicle 1 through the inspection door, thereby ensuring the normal filling and discharge of the fire extinguishing agent.

[0024] Among them, a negative pressure bin 5 is arranged inside the protective shell 4, and a suction conveying blower 6 located inside the protective shell 4 and connected to the negative pressure bin 5 is fixedly installed on the top of the conveying vehicle 1. A variable frequency motor and a variable frequency controller are arranged inside the suction conveying blower 6, which is convenient for adjusting the power of the suction conveying blower 6 during use, thereby controlling the amount of suction.

[0025] Among them, a dust collector 7 is arranged inside the protective shell 4, a transport rotary feeder 8 is fixedly installed at the bottom of the negative pressure bin 5 and the dust collector 7, a first soft connecting pipe 9 is fixedly installed on the suction conveying blower 6 and the transport rotary feeder 8, an acceleration chamber 10 located at the transport rotary feeder 8 is fixedly installed on the outer side of the first soft connecting pipe 9, and a high-pressure induced draft fan 11 is arranged on the right side of the dust collector 7, and a negative pressure is formed inside the dust collector 7 by the high-pressure induced draft fan 11, so as to facilitate the inhalation of dust.

[0026] In this embodiment, the filling and discharging mechanism also includes a second soft connecting pipe 12 fixedly installed on the right side of the dust collector 7. A through hole is opened on the right side of the protective shell 4. The first soft connecting pipe 9 and the second soft connecting pipe 12 are extended to the outside of the protective shell 4 through the through hole. A control cabinet 13 is arranged on the front of the protective shell 4. Dust hoods 14 are arranged on the outside of the first soft connecting pipe 9 and the second soft connecting pipe 12. The size of the dust hood 14 is larger than that of the feed pipe 3, so that the top of the feed pipe 3 can be completely wrapped by the dust hood 14, so as to better absorb the dust. A suction pipe 15 extending to the outside of the protective shell 4 is arranged on the right side of the negative pressure bin 5, and a fire extinguishing agent bag 16 is arranged at the end of the suction pipe 15.

[0027] It should be added that the high-pressure induced draft fan 11 creates a negative pressure state inside the dust collector 7, and the second soft connecting pipe 12 sucks the dust at the feed pipe 3. After the dust enters the dust collector 7, it falls into the transport rotary feeder 8 due to gravity and is transported to the fire truck 2 again through the first soft connecting pipe 9, thereby reducing material waste.

[0028] There is no fixed model of the equipment, and other equipment can be configured according to actual production needs. After the pipeline interface comes out, it can be connected with a hose to increase the convenience of mobile operation. The external connecting pipe, blowing pipe, and exhaust pipe are all flexible to increase adaptability. According to the actual site environment, it can be lengthened or shortened to change the conveying distance or height. By adjusting the frequency converter, the actual output of the conveying can be controlled. The power supply can be connected to the site according to the site environment, or a mobile diesel (gasoline) generator can be configured to provide more convenience for mobile operations of enterprises.

[0029] It should be noted that the adjustable fire extinguishing agent filling and discharging device, through the filling and discharging mechanism, when the fire truck 2 needs to be filled or discharged with fire extinguishing agent, the fire extinguishing agent is transported to the interior of the fire truck 2 through the mutual cooperation between the various structures on the transport vehicle 1, and the raised dust is absorbed during the transportation process to prevent its leakage from polluting the environment and affecting the health of surrounding workers, thereby helping to improve the fire extinguishing agent filling and discharge efficiency of the fire truck 2.

[0030] The working principle of the above embodiment is:

[0031] The adjustable fire extinguishing agent filling and discharging device, when it is necessary to fill the fire extinguishing agent into the fire truck 2, firstly extend the first soft connecting pipe 9 and the second soft connecting pipe 12 into the fire truck 2, and use the dust collecting hood 14 to cover the feeding pipe 3 on the top of the fire truck 2, then start the suction conveying blower 6 through the control cabinet 13, and convey the fire extinguishing agent in the fire extinguishing agent ton bag 16 to the negative pressure bin 5 through the suction pipe 15, and then drop from the bottom of the negative pressure bin 5 to the transport rotary feeder 8, and under the action of the acceleration chamber 10, the fire extinguishing agent is conveyed to the fire truck 2 through the first soft connecting pipe 9, and the high-pressure induced draft fan 11 is started at the same time of conveying, and the oxygen dust is absorbed into the dust collector 7 through the second soft connecting pipe 12 on the right side of the dust collector 7, so as to avoid dust leakage and pollution to the environment, and when it is necessary to discharge the fire extinguishing agent in the fire truck 2, it is only necessary to exchange the position of the suction pipe 15 and the first soft connecting pipe 9 to realize the discharge of the fire extinguishing agent.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
