It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] Embodiment 1:

[0021] See also Figure 1-7 The utility model provides a technical solution: a fire-fighting water intake device, comprising a spherical housing 100, wherein a water filling cavity 107 is provided in the spherical housing 100, wherein the spherical housing 100 is fixedly connected to a hollow tube 104 with one end located in the water filling cavity 107 and one end located on the upper side of the spherical housing 100, wherein a ventilation pipe 112 is provided in the hollow tube 104, wherein the hollow tube 104 is fixedly connected to four side plates 109 distributed in a circumferential row, wherein each of the side plates 109 is fixedly connected to a hydraulic pump 1 10. The spherical housing 100 is provided with four water holes 114 distributed in a circular array. The water holes 114 are coaxially aligned with the hydraulic pump 110 one by one. The hydraulic pump 110 is dynamically connected to a sealing cover 101. The spherical housing 100 is provided with four snap-in grooves 118 coaxially aligned with the water holes 114. The sealing cover 101 can be snapped into the snap-in grooves 118 for sealing, so that the sealing cover 101 can be opened and closed to load and unload the fire-fighting water in the water-filling chamber 107.

[0022] Each of the clamping grooves 118 is provided with two upper and lower through holes 119, and a positioning rod 116 having one end fixedly connected to the sealing cover 101 is slidably connected to the through hole 119, and each of the positioning rods 116 is slidably connected to a fixing rod 108, and the other end of the fixing rod 108 is fixedly connected to the hollow tube 104, thereby playing a role in limiting the movement of the sealing cover 101;

[0023] The right side plate 109 is fixedly connected with a remote control device 113, and the hydraulic pump 110 is controlled to start and stop by the remote control device 113;

[0024] The hollow tube 104 is provided with four air holes 111 located in the water filling chamber 107. The air holes 111 and the ventilation pipe 112 can ensure the air pressure inside and outside the water filling chamber 107 when loading and unloading water, thereby ensuring the rapid loading and unloading of water.

[0025] The spherical housing 100 is fixedly connected to four fixing plates 102 distributed in a circular array, and a connecting rope 103 is fixedly connected to the upper end surface of each fixing plate 102. The other end of the connecting rope 103 is fixedly connected to a connecting plate 105. The connecting plate 105 is coaxially aligned with the hollow tube 104 in the upper and lower directions, and a main rope 106 connected to a helicopter is fixedly connected to the upper end surface of the connecting plate 105, so that the spherical housing 100 can be smoothly driven to move by the helicopter.

[0026] Working principle:

[0027] The main rope 106 is fixedly connected to the helicopter, and then the main rope 106 is pulled by the helicopter to move, and the hollow tube 104 is used to improve the stability of the spherical housing 100, and the remote control device 113 is remotely controlled in advance to start the hydraulic pump 110, and the hydraulic pump 110 drives the sealing cover 101 to start, and the sealing cover 101 moves out of the clamping groove 118;

The air hole 111 and the ventilation pipe 112 can ensure that the air pressure inside and outside the spherical housing 100 is consistent, so as to ensure the rapid loading and unloading of water. After the water-filling chamber 107 is filled with water, the hydraulic pump 110 is started again, and the hydraulic pump 110 drives the sealing cover 101 to move again and snap into the snap-in groove 118 for sealing. Then, the spherical housing 100 is pulled out of the tax by a helicopter and moved to the top of the fire. After opening the sealing cover 101, the water is poured out to quickly extinguish the fire.

[0029] When the sealing cover 101 moves, the positioning rod 116 slides in the rod groove 117 of the fixing rod 108 to ensure the stability of the movement of the sealing cover 101 and to play a limiting role at the same time.
