Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to fire-fighting hose detection equipment with automatic water filling and pressure stabilization. Background Art

[0002] Fire hoses are used to deliver high-pressure water when extinguishing fires at the scene of a fire. Their quality is related to the safety of life and property, so fire hoses need to be inspected regularly.

[0003] However, when conducting pressure resistance tests on fire hoses, the fire hoses are usually inspected manually by visually inspecting them. This method has poor detection effects and low detection accuracy. In addition, after the test, the water in the fire hose is not easy to recover, which easily leads to a waste of water resources.

[0023] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0024] The utility model provides a fire hose detection device with automatic water filling and pressure stabilization, comprising:

[0025] The water tank 1 has a water outlet pipe connected to the side wall, and a water inlet connected to the upper wall of the water tank 1, which can facilitate the staff to add water from the outside into the water tank 1. The water outlet pipe is fixedly connected to the side wall of the water tank 1, which can facilitate the water in the water tank 1 to flow out;

[0026] The detection box 2 is arranged on the upper end surface of the water tank 1, and the side wall is connected with a water inlet pipe. The lower end surface of the detection box 2 is welded to the upper end surface of the water tank 1, so that the detection box 2 and the water tank 1 can be fixed to each other, and the water inlet pipe is fixedly connected with the side wall of the detection box 2;

[0027] A connecting pipe 3 is connected to one end of the water outlet pipe. One end of the connecting pipe 3 is threadedly connected to one end of the water outlet pipe, so that one end of the connecting pipe 3 is fixedly connected to one end of the water outlet pipe.

[0028] The first solenoid valve 4 is arranged on the connecting pipe 3. The first solenoid valve 4 is fixedly mounted on the connecting pipe 3. When the first solenoid valve 4 is opened, the water in the water tank 1 can flow out from the connecting pipe 3. When the first solenoid valve 4 is closed, the connecting pipe 3 can be sealed to prevent the water from flowing out.

[0029] The two ends of the fire hose 5 are respectively connected to one end of the connecting pipe 3 and one end of the water inlet pipe. The two ends of the fire hose 5 are respectively threadedly connected to the water inlet pipe and one end of the connecting pipe 3, which can facilitate the water in the water tank 1 to flow into the fire hose 5;

[0030] The drain pipe 6 has one end connected to the side wall of the detection box 2 and the other end penetrating the upper wall of the water tank 1. The drain pipe 6 can allow the water in the detection box 2 to flow back into the water tank 1;

[0031] The second solenoid valve 7 is arranged on the drain pipe 6. The second solenoid valve 7 is fixedly mounted on the drain pipe 6. When the second solenoid valve 7 is opened, the water in the detection box 2 can flow back to the water tank 1. When the second solenoid valve 7 is closed, the drain pipe 6 can be closed to prevent water from flowing into the water tank 1.

[0032] The water pressure sensor 8 is arranged in the detection box 2. The water pressure sensor 8 is fixedly mounted on the inner wall surface of the detection box 2, and can detect the water pressure in the fire hose 5 and the detection box 2;

[0033] The water pump 9 is arranged on the lower end surface of the water tank 1, and the water outlet end is connected with one end of the water outlet pipe. The water pump 9 is fixedly installed on the lower end surface of the interior of the water tank 1. When the staff starts the water pump 9, the water in the water tank 1 can be pumped and transported to the water outlet pipe at the same time.

[0034] Specifically, a control panel 10 is installed on the outer wall of the water tank 1. The control panel 10 is electrically connected to the water pressure sensor 8 and the water pump 9 respectively. The control panel 10 is fixedly installed on the outer wall of the water tank 1 and can remain fixed. At the same time, the water pressure sensor 8 can transmit the detected pressure value to the control panel 10 and display it, which is convenient for the staff to watch and record. At the same time, the control panel 10 can control the opening or closing of the water pump 9, which is convenient for pumping the water in the water tank 1.

[0035] Specifically, a glass window 11 for observation is installed on the side wall of the water tank 1. The glass window 11 allows the staff to observe the water level in the water tank 1 and the water outflow of the drain pipe 6 at the same time.

[0036] Specifically, rollers 12 for movement are installed on the lower end surface of the water tank 1. There are two pairs of rollers 12, which are rotatably installed on the lower end surface of the water tank 1, so that the staff can move and transport the water tank 1 conveniently.

[0037] Specifically, a handle 13 is installed on the outer wall of the water tank 1 . The handle 13 is a pair and both are welded to the outer wall of the tank body 1 , so that the staff can push the water tank 1 conveniently.

[0038] Working principle: First, the staff injects external water into the water tank 1 from the water inlet. At this time, the staff connects the two ends of the fire hose 5 to one end of the water outlet pipe and one end of the connecting pipe 3 respectively. The staff starts the water pump 9 and opens the first solenoid valve 4 and the second solenoid valve 7 at the same time. The water pump 9 pumps the water in the water tank 1 and transports it to the connecting pipe 3 and the fire hose 5. At this time, the staff observes the drain pipe 6 through the glass window 11. When water flows out of one end of the drain pipe 6, it proves that there is no air in the fire hose 5. At this time, the staff closes the second solenoid valve 7 to prevent water from flowing out of the detection box 2. At this time, because the detection box 2 is closed, the water pressure in the detection box 2 and the fire hose 5 increases. At the same time, the water pressure sensor 8 transmits the detected pressure value to the control panel 10, which is displayed on the control panel 10. When the water pressure reaches the detected value, the staff turns off the water pump 9 and the first solenoid valve 4 at the same time. The first solenoid valve 4 is closed to stabilize the water pressure in the fire hose 5 and the detection box 2. At this time, the staff observes the water pressure value on the control panel 10. When the water pressure value decreases, it means that the fire hose 5 is damaged. Otherwise, the fire hose 5 is intact. After the detection is completed, the staff disassembles the connection between the water inlet and the connecting pipe 3, and opens the first solenoid valve 4 at the same time. The water in the fire hose 5 and the detection box 2 can be collected to prevent waste, which brings convenience to people.
