AI Technical Summary
During the spraying process of the existing fire extinguisher coating device, it is difficult for the nozzle to accurately aim at the inner wall of the fire extinguisher tank mouth, resulting in incomplete coating. In addition, the lack of flexibility of the telescopic parts or control errors may cause the coating liquid to be sprayed to the outside of the tank or the inner wall port to remain uncoated.
A pressure sensor and controller are used in conjunction with a water pump. The resistance signal at the tank opening is sensed through the connector to automatically control the opening and closing of the nozzle and the spraying time to ensure that the coating liquid is accurately sprayed on the inner wall of the tank, including the use of elastic reeds and limit plates or movable telescopic sleeves to achieve precise control.
The comprehensiveness and accuracy of the coating on the inner wall of the fire extinguisher are achieved, the waste and incompleteness of the coating liquid are avoided, and the uniformity and efficiency of the coating are improved.

[0003] At present, when coating the inner wall of a fire extinguisher, a coating nozzle is usually driven by a telescopic part to enter the interior of the fire extinguisher tank. Under the action of pressure, the coating material is sprayed out from the nozzle and deposited on the inner wall of the fire extinguisher in a direction. However, due to the small diameter of the fire extinguisher tank mouth, when the telescopic part drives the sprinkler head to initially enter the tank body, it may be affected by the flexibility of the telescopic part or the control error, or the different heights of tanks of different specifications may cause the extension length of the telescopic part to be not adjusted in time. If the spraying is too early, the coating liquid will be sprayed to the outside of the tank body. If the spraying is too late, the port of the inner wall of the tank will partially not be sprayed with the coating liquid, resulting in the nozzle being unable to accurately spray and coat the inner wall of the tank mouth, and the coating is not comprehensive. Based on the above situation, it is necessary to design a fire extinguisher coating device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific drawings.
[0022] Referring to Figures 1-6 As shown in the figure, a fire extinguisher coating device, including for containing the containing part 11 and coating assembly 2 for tank body 1, coating assembly 2 includes spray head 21 and the material conveying hose 22 connected with spray head 21, and the input end of the material conveying hose 22 is connected with the container 23 for containing coating liquid, the material conveying hose 22 is equipped with water pump 24, still including the telescopic part 4 installed on the working frame 3, the telescopic part 4 coincides with the shaft center of the tank body 1, the movable end of the telescopic part 4 is connected with the spray head 21, for driving the spray head 21 to extend into the tank body 1 inside and carry out coating treatment, the telescopic part 4 can be electric telescopic rod or electric push rod mechanism, when the telescopic part 4 extends and drives the spray head 21 to enter the tank body 1 inside, the coating liquid in the container 23 is sprayed to the inner wall of the tank body 1 through the water pump 24, and the spray head 21 is continuously moved downward along with the telescopic part 4, thereby to carry out the spraying treatment from the top to the bottom of the inner wall of the tank body 1, and the bottom and the periphery of the spray head 21 are equipped with downward inclined spray ports, to carry out the spraying of the bottom inner wall of the tank body 1 when the spray head 21 moves to the lower end of the tank body 1, in order to spray the coating liquid in time when the spray head 21 enters the port of the tank body 1, still including the connecting part 5, the connecting part 5 is equipped with the pressure sensor 6, when the connecting part 5 moves to the opening end of the tank body 1 and is in contact, the pressure sensor 6 generates pressure signal in contact with the tank body 1, the output end of the pressure sensor 6 is electrically connected with the controller 61, and the output end of the controller 61 is used for outputting control signal, after the controller 61 receives the pressure signal of the pressure sensor 6, the water pump 24 is controlled to open and carry out coating work, which will be described in detail below in combination with specific embodiments.
[0023] As Figure 3-4As shown, this is the first embodiment provided by the present invention, the connecting member 5 includes a connecting plate 51 and a movable telescopic sleeve 52 connected to the upper end of the connecting plate 51, the pressure sensor 6 is installed at the lower end of the connecting plate 51, and a limit plate 53 is provided on the movable end of the telescopic member 4, the limit plate 53 is located between the connecting plate 51 and the nozzle 21, and is used to limit the position of the pressure sensor 6, the movable telescopic sleeve 52 is composed of at least two connecting pipes that slide with each other, when the telescopic member 4 drives the nozzle 21 to move downward and extend into the interior of the tank body 1, the pressure sensor 6 is driven by the gravity of the connecting plate 51 itself. The nozzle 21 moves upward to extend from the tank body 1, and the connecting plate 51 moves upward under the action of the limit plate 53, so that the two connecting pipes slide and the movable telescopic sleeve 52 is contracted. After the pressure sensor 6 is out of contact with the tank body 1, the spraying operation is stopped.
[0024] like Figure 5-6 As shown, this is a second embodiment of the present invention. The connecting member 5 includes an elastic spring 501 connected to the nozzle 21 and a connecting rod 502 connected to the elastic spring 501. The pressure sensor 6 is installed at one end of the connecting rod 502 away from the elastic spring 501. When the telescopic member 4 drives the nozzle 21 into the port of the tank body 1, the nozzle 21 drives the elastic spring 501 to come into conflict with the inner wall of the tank body 1. The elastic spring 501 is deformed to cause the connecting rod 502 to drive the pressure sensor 6 to come into conflict with the outer wall of the movable end of the telescopic member 4, thereby generating a pressure signal to turn on the water pump 24 for spray coating. Working, as the telescopic part 4 continues to move downward, the inner diameter of the tank body 1 becomes larger, and the elastic spring 501 recovers its deformation. Then, when the telescopic part 4 contracts and drives the nozzle 21 to move upward, the elastic spring 501 again conflicts with the inner wall of the port of the tank body 1, so that the connecting rod 502 drives the pressure sensor 6 to conflict with the outer wall of the movable end of the telescopic part 4 to turn off the water pump 24. The material of the connecting rod 502 is elastic material, such as rubber. When the elastic spring 501 drives the connecting rod 502 to conflict with the nozzle 21, the connecting rod 502 made of elastic material can be deformed to avoid the phenomenon of the connecting rod 502 breaking.
[0025] The other end of the first reed can also be connected with the movable end outer wall of the telescopic part 4. The mounting positions of the connecting plate 51 and the connecting rod 502 are on the upper end surface of the spray head 21. When the connecting plate 51 or the connecting rod 502 drives the pressure sensor 6 to generate a pressure signal, the upper end surface of the spray head 21 is just flush with the upper end surface of the port of the tank body 1. Thus, the spraying and plating can be performed from the uppermost part of the port of the tank body 1, so as to improve the comprehensiveness of plating.
[0026] Further, the holding part 11 or the plating assembly 2 can rotate. Specifically, a rotating device can be mounted on the plating assembly 2 or the holding part 11 during use, so as to realize the rotation of the holding part 11 driving the tank body 1 or the rotation of the plating assembly 2 driving the spray head 21. Thus, the downward movement of the spray head 21 driven by the telescopic part 4 can be realized, so as to realize the comprehensive spraying on the inner wall of the tank body 1. Since the plating assembly 2 needs a large space during rotation and is inconvenient to rotate, the holding part 11 is preferably rotated. For example, a driving motor is arranged in the holding recess 12 of the holding part 11 on the working frame 3, so as to drive the tank body 1 in the holding recess 12 to rotate (not shown in the figure). This technology is prior art and is known to those skilled in the art, and thus will not be described in detail. A plurality of holding recesses 12 can be arranged on the holding part 11, and a rotating mechanism can be arranged at the bottom of the holding part 11. After the tank body 1 at the bottom of the spray head 21 is plated, the holding recesses 12 at other positions can be moved to the bottom of the spray head 21 through the rotation of the holding part 11. The tank body 1 after plating is taken out, and a tank body 1 before plating is put in, so as to improve the working efficiency.
[0027] As shown in Figure 2 , when the tank body 1 rotates, in order to reduce the friction between the tank body 1 and the connecting plate 51, the movable plate 7 is rotatably connected to the working frame 3. The movable telescopic sleeve 52 is connected to the movable plate 7. When the tank body 1 rotates and rubs against the connecting plate 51, the rotation of the movable plate 7 driven by the movable telescopic sleeve 52 can make the connecting plate 51 move, so as to avoid the large friction between the connecting plate 51 and the tank body 1, and thus avoid the abrasion of the port of the tank body 1.
[0028] Further, as shown in Figure 4 , when the connecting plate 51 abuts against the opening of the tank body 1, the opening of the tank body 1 is blocked. Specifically, the shape and number of the connecting plate 51 are not limited. When the connecting plate 51 abuts against the port of the tank body 1 under the action of its own gravity, the port of the tank body 1 is blocked, so as to avoid the spraying of the plating liquid to the outside of the tank body 1 when the spray head 21 below sprays and plates.
[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
