[0009] Furthermore, the two springs are movably sleeved on the outer walls of the two telescopic rods, and one end of the third gear of the two springs is fixedly connected to the inner wall of the long frame.

[0010] Furthermore, the multiple sliders are arranged in pairs, forming two groups. The sliders in the two groups are threadedly connected to the outer walls of the two bidirectional screws.

[0016] 1. This utility model proposes a helicopter precision fire-fighting water cannon device. A centrifugal pump draws water from a water tank, which is then sprayed through a rigid pipe and guide block via a first pipe. An electrical signal from the control panel inside the helicopter causes a second motor to drive a first gear, a second gear, and a first pipe, continuously adjusting the lateral spray angle. The control panel also sends an electrical signal to a second motor to drive a rotating ring, which in turn drives the stainless steel corrugated section of the first pipe to rotate, adjusting the longitudinal spray angle. Different spray angles can be adjusted without requiring the helicopter itself to adjust its position. 2. This utility model also proposes a helicopter precision fire-fighting water cannon device. By moving the locking block to the right and rotating the bidirectional screw, two sliders move in opposite directions, entering the base. The same operation is performed on the other side. When all four sliders are inside the long frame, the entire device is fixed to the bottom of the helicopter, allowing for quick disassembly for replacement or cleaning. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-6This utility model provides an embodiment of a helicopter precision fire-fighting water cannon device, including an adjustment mechanism 1, a locking mechanism 2, and two bases 208. The adjustment mechanism 1 includes a centrifugal pump 101, a first gear 108, and a first motor 104. An iron pipe 111 is fixedly connected to the inner wall of the rear end of the centrifugal pump 101. A guide block 109 is fixedly connected to the outer wall of the bottom of the iron pipe 111. A first pipe 103 is rotatably connected to the inner wall of the bottom of the guide block 109. A second gear 110 is fixedly connected to the outer wall of the first pipe 103 near the top. The outer wall of the bottom of the first pipe 103 is fixed. A drive ring 102 is provided. The output end of the first motor 104 is fixedly connected to the outer wall of the rear end of the drive ring 102. The locking mechanism 2 includes two long frames 201. Two sliders 204 are slidably connected to the inner walls of the two long frames 201. A bidirectional screw 202 is connected to the center of the inner wall of the two long frames 201 through a bearing. A third gear 203 is fixedly provided on the outer wall of the two bidirectional screws 202 near the center. A locking block 205 is slidably connected to the outer wall of the two third gears 203. A spring 207 is fixedly connected to the end of the two locking blocks 205 away from the third gear 203.

[0027] Specifically, the centrifugal pump 101 is activated to draw water from the water tank, which then enters the guide block 109 through the iron pipe 111. The water is then sprayed out through the first pipe 103. The control panel inside the helicopter controls the electrical signals to activate the second motor 107, which in turn drives the first gear 108 to rotate. The first gear 108 drives the second gear 110 and the first pipe 103 to rotate along the inner wall of the top guide block 109, adjusting the lateral spray angle. The top of the first pipe 103 is embedded inside the guide block 109 and does not move, only rotates. The control panel inside the helicopter controls the electrical signals to activate the second motor 107, which drives the ring 102 to rotate, causing the bottom of the first pipe 103 to be a stainless steel corrugated pipe. Partial rotation adjusts the longitudinal spray angle, allowing the spray nozzle to rotate laterally without dead angles and adjust longitudinally over a wide range. When the locking block 205 moves to the right and slides out of the inside of the third gear 203, the bidirectional screw 202 rotates, causing the two sliders 204 to move along the inner wall of the long frame 201 in the front and rear directions and enter the inside of the front and rear bases 208. The same operation is performed on the other side. When multiple sliders 204 enter the inner wall of the long frame 201, the whole is fixed. Then, release the lever, and the locking block 205 will be locked between the two teeth of the third gear 203 under the action of the spring 207, preventing the third gear 203 from rotating and causing the spray nozzle to become unstable.

[0028] Reference Figures 1-6Two locking blocks 205 are fixedly connected to telescopic rods 206 at their ends away from gear 3 203. The ends of the two telescopic rods 206 away from gear 3 203 are fixedly connected to the inner wall of the long frame 201. Two springs 207 are movably sleeved on the outer walls of the two telescopic rods 206. The ends of the two springs 207 away from gear 3 203 are fixedly connected to the inner wall of the long frame 201. Multiple sliders 204 are arranged in pairs, forming two groups. The interiors of the two groups of sliders 204 are threadedly connected to the outer walls of two bidirectional screws 202. The ends of the two groups of sliders 204 away from gear 3 203 are slidably set on the inner walls of the two bases 208, driving the inner wall of the ring 102 to be fixedly connected to the bottom outer wall of tube 103. A locking plate 105 is fixedly connected to the bottom outer wall of tube 103. The upper two-thirds of pipe 103 is a rigid pipe, and the lower one-third of pipe 103 is a stainless steel corrugated pipe. The outer wall of the rear end of motor 104 is fixedly connected to a clamping plate 105. The inner wall of clamping plate 105 is fixedly connected to the rigid pipe. The inner wall of gear 110 is fixedly connected to the rigid pipe at the two-thirds end of pipe 103. Motor 107 is fixedly connected to the bottom center of gear 108. Clamping plate 106 is fixedly connected to the outer wall of motor 107. A water tank is fixedly connected to one end of clamping plate 106 near clamping mechanism 2. Centrifugal pump 101 is fixedly connected to the inner wall of water tank via a water pipe at one end near water tank. Centrifugal pump 101 is fixedly connected to the outer wall of water tank at one end near water tank. Gear 108 and gear 110 mesh with each other.

[0029] Specifically, the telescopic rod 206 prevents the spring 207 from tilting, ensuring the compression path of the spring 207. The slider 204 is restricted by the long frame 201 and will not rotate. The part of the multiple sliders 204 that enters the base 208 is U-shaped, which provides a more stable fixing effect than a cylinder. The top two-thirds of the first tube 103 is a rigid tube that provides fixation and support for the first clamping plate 105. The remaining bottom one-third is a stainless steel corrugated pipe that has a certain strength and can be bent at any angle. The second clamping plate 106 provides fixation and support for the second motor 107. The centrifugal pump 101 is fixed together with the water tank. The second clamping plate 106 is fixed together with the water tank. The first gear 108 and the second gear 110 mesh with each other.

[0030] Working principle: The centrifugal pump 101 is started to draw water from the water tank, which enters the iron pipe 111, then the guide block 109, and finally sprays out through the first pipe 103. When adjusting the angle, the second motor 107 is started, and its output end drives the first gear 108 to rotate. The first gear 108 drives the second gear 110 to rotate. The second gear 110 drives the first pipe 103 to rotate along the inner wall of the top guide block 109, continuously adjusting the horizontal spray angle. The output end of the second motor 107 is started to drive the drive ring 102 to rotate. The drive ring 102 drives the stainless steel corrugated part at the bottom of the first pipe 103 to rotate, adjusting the vertical spray angle.

[0031] Secondly, when fixing the overall mechanism, first move the locking block 205 to the right. When the locking block 205 slides out from inside the third gear 203, rotate the double-acting screw 202 to make the two sliders 204 move along the inner wall of the long frame 201 in the front and back directions and enter the base 208 on the front and back sides. The same operation is performed on the other side. When multiple sliders 204 enter the inner wall of the long frame 201, the whole can be fixed. Then release the lock and let the locking block 205 enter between the two teeth of the third gear 203 under the action of the spring 207 to fix the third gear 203.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
