Description

Technical Field

[0001] This utility model relates to the field of fire hydrant technology, and in particular to a fire hydrant that supports multiple positioning methods and can automatically switch positioning modes. Background Technology

[0002] Fire hydrants are fixed fire-fighting facilities mainly used to connect fire hoses and nozzles to transport fire-fighting water for extinguishing fires. They are an important part of the urban fire protection system. As a basic fire-fighting facility, the proper design, correct use, and regular maintenance of fire hydrants are crucial for fire fighting. The public needs to understand their location and how to use them so that they can respond quickly in emergencies.

[0003] In the existing technology, fire hydrants are fixedly installed on the ground to ensure stable use. However, in actual use, fire hydrants are not easy to adjust in terms of angle according to usage needs, which can cause water pipes to become tangled during subsequent use. This not only affects the water supply but also causes damage. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, fire hydrants are fixed on the ground to ensure stable use, but in actual use, the angle of the fire hydrant cannot be flexibly adjusted according to the needs of use, which will cause the water pipe to become entangled during subsequent use, which will not only affect the water supply but also cause damage. Therefore, this invention proposes a fire hydrant that supports multiple positioning methods and can automatically switch positioning modes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fire hydrant that supports multiple positioning methods and can automatically switch positioning modes includes a base and a fire hydrant. A connecting ring is fixedly connected to the bottom of the fire hydrant. A connecting plate is fixedly connected to the side wall of the base. A servo motor is fixedly connected to the bottom of the connecting plate. The output shaft end of the servo motor passes through the connecting plate and is fixedly connected to a connecting shaft. A gear is fixedly sleeved on the shaft wall of the connecting shaft. Multiple teeth are fixedly connected around the side wall of the connecting ring, and the multiple teeth are respectively meshed with the gear.

[0007] Preferably, the fire hydrant has a connecting sleeve inside, and the bottom inner wall of the base is rotatably connected to an encoding controller, with the connecting sleeve positioned above the encoding controller.

[0008] Preferably, a connecting seat is fixedly connected to the side wall of the base, and a water supply pipe is provided on the side wall of the connecting seat, the water supply pipe extending into the interior of the connecting sleeve.

[0009] Preferably, the water supply pipe is configured as a spiral pipe.

[0010] Preferably, the top inner wall of the base is provided with an annular groove, and the bottom of the connecting ring is fixedly connected with a guide slider, which is slidably disposed on the inner wall of the annular groove.

[0011] Preferably, the bottom of the guide slider is provided with rolling balls, which are rolled on the inner wall of the annular groove.

[0012] Compared with the prior art, this utility model provides a fire hydrant that supports multiple positioning methods and can automatically switch positioning modes, and has the following beneficial effects:

[0013] 1. This fire hydrant, which supports multiple positioning methods and can automatically switch positioning modes, is equipped with a servo motor mounted at the bottom of the connecting plate. Its output shaft drives the connecting shaft and gear to rotate. The gear meshes with the teeth on the side wall of the connecting ring, thereby driving the fire hydrant to rotate and achieve orientation adjustment. The connecting sleeve inside the fire hydrant works with the encoder controller in the base. The encoder controller can monitor the rotation angle and position of the fire hydrant in real time, convert the data into electrical signals and transmit them to the control system to achieve angle positioning function. When it is necessary to switch positioning modes, the control system can automatically adjust the operation of the servo motor according to the requirements to complete the positioning mode switch.

[0014] 2. This fire hydrant supports multiple positioning methods and can automatically switch positioning modes. It connects to the water supply pipe through the connecting seat on the side wall of the base. The water supply pipe is a spiral tube that can extend, retract, or bend with the fire hydrant as it rotates, avoiding the twisting and breaking of the water supply pipe due to the rotation of the fire hydrant, ensuring smooth water supply. The spiral tube design allows the water supply pipe to move freely within a certain range while maintaining sealing performance.

[0015] 3. This fire hydrant supports multiple positioning methods and can automatically switch positioning modes. The connecting ring at the bottom of the fire hydrant cooperates with the annular groove at the top of the base through the guide slider. The ball bearings at the bottom of the guide slider can reduce friction and allow the connecting ring to rotate flexibly. The small gap between the guide slider and the annular groove can ensure that the fire hydrant can rotate flexibly and prevent it from shaking up and down. The ball bearings are made of stainless steel to reduce friction. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A fire hydrant that supports multiple positioning methods and can automatically switch positioning modes includes a base 1 and a fire hydrant 2. A connecting ring 3 is fixedly connected to the bottom of the fire hydrant 2. A connecting plate 4 is fixedly connected to the side wall of the base 1. A servo motor 5 is fixedly connected to the bottom of the connecting plate 4. The output shaft end of the servo motor 5 passes through the connecting plate 4 and is fixedly connected to a connecting shaft 6. A gear 7 is fixedly sleeved on the shaft wall of the connecting shaft 6. Multiple teeth 8 are fixedly connected around the side wall of the connecting ring 3. The multiple teeth 8 are respectively meshed with the gear 7. A connecting sleeve 10 is provided inside the fire hydrant 2. An encoder controller 11 is rotatably connected to the bottom inner wall of the base 1. The connecting sleeve 10 is located above the encoder controller 11.

[0022] A connecting seat 9 is fixedly connected to the side wall of the base 1. A water supply pipe 12 is provided on the side wall of the connecting seat 9. The water supply pipe 12 extends into the interior of the connecting sleeve 10 and is configured as a spiral tube.

[0023] Servo motor 5 is installed at the bottom of connecting plate 4. Its output shaft drives connecting shaft 6 and gear 7 to rotate. Gear 7 meshes with teeth 8 on the side wall of connecting ring 3, thereby driving fire hydrant 2 to rotate and achieve orientation adjustment. Connecting sleeve 10 inside fire hydrant 2 cooperates with encoder controller 11 in base 1. Encoder controller 11 can monitor the rotation angle and position of fire hydrant 2 in real time, convert the data into electrical signals and transmit them to the control system to achieve angle positioning function. When it is necessary to switch the positioning mode, the control system can automatically adjust the operation of servo motor 5 according to the requirements to complete the positioning mode switch.

[0024] The connecting seat 9 on the side wall of the base 1 connects to the water supply pipe 12. The water supply pipe 12 is a spiral tube that can extend, retract, or bend with the fire hydrant 2 when it rotates, preventing the water supply pipe from twisting and breaking due to the rotation of the fire hydrant, ensuring smooth water supply. The spiral tube design allows the water supply pipe to move freely within a certain range while maintaining sealing performance.

[0025] When the fire hydrant needs to be positioned at an angle, the encoder controller 11 generates a corresponding encoded signal by detecting the rotation angle of the connecting sleeve 10 to achieve precise angle positioning. If the positioning mode is switched to another mode, the control system will turn off the signal output of the encoder controller 11 and instead receive the position data from the control module. The servo motor 5 adjusts the orientation of the fire hydrant 2 according to the new positioning data to ensure that it is accurately aligned with the water source or rescue position.

[0026] In order for the connecting ring 3 to rotate flexibly, such as Figure 1-3 As shown, an annular groove is provided on the inner wall of the top of the base 1, and a guide slider 13 is fixedly connected to the bottom of the connecting ring 3. The guide slider 13 is slidably disposed on the inner wall of the annular groove, and a ball bearing 14 is rolled on the bottom of the guide slider 13.

[0027] The connecting ring 3 at the bottom of the fire hydrant 2 is engaged with the annular groove at the top of the base 1 via the guide slider 13. The ball bearing 14 at the bottom of the guide slider 13 can reduce friction and allow the connecting ring 3 to rotate flexibly. The clearance between the guide slider 13 and the annular groove is designed to be 0.1-0.3mm, which can ensure that the fire hydrant 2 rotates flexibly and prevent it from shaking up and down. The ball bearing 14 is made of stainless steel to reduce friction.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
