DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative work fall within the protection scope of the utility model.

[0023] Please refer to Figs. 1 to 3 A portable fire pump, including fire pump body 1, fire pump body 1 outside is provided with the carrying structure 2 for carrying loading and the support structure 3 installed below fire pump body 1;Carrying structure 2 includes loading box 201, handle 202, gyro wheel 203, support leg 204 and conveying structure;Conveying structure includes servo motor 206, screw 207 and bearing table 205, one end of screw 207 is fixed with servo motor 206 output shaft, and the other end of screw 207 extends into the inside of bearing table 205, and bearing table 205 is screw connected with screw 207. Servo motor 206 is fixedly installed on the back of loading box 201, and screw 207 extends to the inside of loading box 201.

[0024] Specifically, loading box 201 is hollowly arranged, and a sealing cover is hingedly installed on one side of the outer portion of loading box 201, and handle 202 is fixedly installed on the outer surface of loading box 201. A support fixed with the lower surface of loading box 201 is rotatably installed on the outer portion of gyro wheel 203, and support leg 204 is fixedly installed on the lower surface of loading box 201. Loading box 201 is further provided with two positioning structures for clamping fire pump body 1. A shoulder strap is installed on the side of loading box 201 close to handle 202. Through the use of shoulder strap, handle 202 and gyro wheel 203, different carrying modes can be realized.

[0025] In this embodiment, the bearing table 205 is fixedly connected with the guide block 208 on both sides, which is slidingly connected with the inside of the loading box 201. The sliding connection of the guide block 208 with the inside of the loading box 201 provides stable guidance for the displacement of the bearing table 205, preventing it from shaking or deviating from the predetermined track during movement. The upper surface of the bearing table 205 is bolted with a protective pad 209 to prevent the fire pump body 1 from sliding. The protective pad 209 is usually made of soft and wear-resistant materials such as rubber or plastic, which can effectively buffer and disperse the impact force of the fire pump body 1 on the bearing table, thereby protecting it from damage. At the same time, the sliding connection of the guide block 208 also helps to reduce the wear of the bearing table on the loading box 201 during movement, prolonging the service life of the equipment. The displacement distance of the bearing table 205 is matched with the length of the lead screw 207, and a limiting block is also installed in the loading box 201 for sliding connection with the guide block 208 to limit the displacement of the bearing table 205, avoiding the bearing table 205 from disengaging from the loading box 201.

[0026] In this embodiment, the support structure 3 includes a mounting table 301, a threaded sleeve 303, a lifting screw 304, and a support block 305. The mounting table 301 is bolted with a pad 302 between the fire pump body 1. The installation of the pad 302 not only increases the contact area between the mounting table 301 and the fire pump body 1, but also disperses the pressure, and plays a buffering and damping role. This helps to protect the fire pump body 1 from vibration and impact, prolonging its service life. The threaded sleeve 303 is rotatably installed on the upper surface of the mounting table 301, the lifting screw 304 penetrates the inside of the mounting table 301 and the threaded sleeve 303, and the lifting screw 304 is threadedly connected with the threaded sleeve 303. The support block 305 can realize stable support of the fire pump body 1 through the threaded connection of the lifting screw 304 and the threaded sleeve 303. This design not only prevents the pump from shaking or tilting during work, but also ensures its stable operation.

[0027] Moreover, by rotating the rotating sleeve 306 to drive the threaded sleeve 303 to rotate, and then driving the lifting screw 304 to move up and down, the height of the support block 305 can be easily adjusted. This height adjustability enables the support structure to adapt to different terrains and installation requirements, ensuring that the fire pump body 1 is in the best working position.

[0028] Specifically, the outer surface of the threaded sleeve 303 is fixedly installed with a rotating sleeve 306, the support block 305 is fixedly installed at the bottom end of the lifting screw 304, the threaded connection has self-locking property, which can prevent the lifting screw 304 from moving accidentally due to external force to a certain extent, thereby ensuring the stability and accuracy of the support height. In addition, by accurately controlling the number of turns of the rotating sleeve 306, fine adjustment of the support height can be realized. The number of mounting tables 301 is two, and the number of threaded sleeves 303, lifting screws 304 and support blocks 305 is four.

[0029] The working principle of the above embodiment is as follows:

[0030] The fire-fighting water pump body 1 is loaded by the carrying structure 2 and is displaced to the required position. When in use, the servo motor 206 is started to drive the lead screw 207 to rotate, the lead screw 207 rotates to drive the bearing table 205 to displace, so that the bearing table 205 moves the fire-fighting water pump body 1 out of the loading box 201, then the rotating sleeve 303 is driven to rotate by the rotating sleeve 306, the rotating sleeve 303 is engaged with the lifting screw 304 to drive the support block 305 to displace up and down, thereby supporting the fire-fighting water pump body 1 to enable stable work.

[0031] The mounting mode, connection mode or setting mode disclosed in the embodiment are all common mechanical connection modes, as long as the beneficial effects can be achieved, and the electrical elements appearing in the embodiment are all electrically connected with the master controller and the power supply. The master controller can be a conventional known device such as a computer which plays a control role. A person skilled in the art can control the electrical elements through simple programming, and the existing disclosed power connection technology also belongs to the common knowledge in the art. Therefore, the specific structure and working principle of the embodiment will not be described in detail.
