Description

Technical Field

[0001] This utility model relates to the field of water intake devices for fire truck water hydrants, and in particular to a water intake device for fire truck water hydrants. Background Technology

[0002] In routine firefighting and rescue missions, water intake is of paramount importance for fire trucks. Therefore, to effectively complete these missions, it is essential to equip them with onboard water intake devices. Currently, the water intake interface for fire truck water cranes generally uses a circular hole with a metal cap. This design is inconvenient in practice. Each time water is added, personnel must climb to the roof via a ladder at the rear of the vehicle to manually align the water crane outlet with the water tank's intake, requiring frequent communication with the driver to ensure accurate stopping and refilling. The entire process is time-consuming and inefficient. Furthermore, the existing water intake interface has a small diameter and lacks an effective flow guiding structure, frequently causing water scattering during refilling. This results in an actual water utilization rate of only 75%, leading to unnecessary waste. Utility Model Content

The sliding door panel 4 is fixedly mounted on the output part of the door panel drive assembly, and the fixing part of the door panel drive assembly is fixedly mounted inside the positioning seat 2. The connecting seat 1 is sealed and fixed to the water tank of the fire truck. The positioning seat 2 is fixed to the connecting seat 1 and can be removed from the connecting seat 1 as needed. The positioning seat 2 has a funnel groove 5 to facilitate alignment with the water crane. With the assistance of the positioning component, quick alignment is achieved without the need for firefighters to operate the water crane, improving water filling efficiency. The funnel groove 5 also expands the water filling range of the water inlet 6 to prevent leakage during water filling. A guide pipe 3 is set to allow more water to enter the water tank, reducing water waste. A sliding door panel 4 is set to close the guide pipe 3 to prevent damage to the vehicle's water pump caused by impurities. The fire truck is equipped with a control center, which is electrically connected to the door panel drive assembly and the positioning assembly. Under the control of the control center, the operation of the door panel drive assembly and the positioning assembly can be controlled.

[0025] In some embodiments, the door panel drive assembly includes a drive motor 7, a transmission screw 8, a sliding block 9, and a guide rail 10.

The heating seat 13 is used to install the heating component 15, which is an electromagnetic heating component in the prior art. The heating component 15 is electrically connected to and controlled by the control center. Under the action of the heating component 15, the device is prevented from being affected by low temperatures, preventing icing and malfunction. Even if ice forms on the guide pipe 3, it will melt, allowing water to be added normally at low temperatures. Simultaneously, the door panel drive assembly will not become stuck due to icing, and the camera 12 will not become blurry or malfunction due to icing.

[0029] In some embodiments, first hooks 16 are fixedly provided on opposite sides of the heating base 13, and first slots that cooperate with the first hooks 16 are provided on the side of the positioning base 2. Second hooks 17 are fixedly provided on all four sides of the connecting base 1, and second slots that cooperate with the second hooks 17 are provided on all four sides of the heating base 13. The connecting base 1 and the heating base 13 are fixedly connected by two electromagnetic lock assemblies, which are arranged symmetrically at the center. The electromagnetic lock assembly includes an electromagnetic component 18, a telescopic lock cylinder 19, a mounting plate 20, and a lock cylinder insert plate 21. The mounting plate 20 is fixedly provided on the connecting base 1, the electromagnetic component 18 is fixedly provided on the mounting plate 20, the telescopic lock cylinder 19 is provided on the output part of the electromagnetic component 18 and cooperates with the insertion hole on the lock cylinder insert plate 21, and the lock cylinder insert plate 21 is fixedly provided on the heating base 13. The first hooks 16 and the second hooks 17 are both prior art. The heating base 13 and the positioning base 2 are connected by two first hooks 16, which facilitates the disassembly of the positioning base 2. The connection between the connecting seat 1 and the heating seat 13 is not only secured by four second hooks 17, but also by an electromagnetic lock assembly. This double-fixing mechanism ensures a more stable connection between the connecting seat 1 and the heating seat 13. The electromagnetic component 18 is existing technology; its function is to drive the telescopic lock cylinder 19 to extend and retract. When the telescopic lock cylinder 19 is inserted into the hole on the lock cylinder insert plate 21, the connecting seat 1 and the heating seat 13 are double-fixed. When the telescopic lock cylinder 19 leaves the hole on the lock cylinder insert plate 21, the connecting seat 1 and the heating seat 13 are only connected by the second hooks 17. The mounting plate 20 serves to fix the electromagnetic component 18 to the connecting seat 1.
