Description

Technical Field

[0001] This utility model generally relates to the field of fire truck technology, and more specifically, to a fire truck water supply test device and recovery system. Background Technology

[0002] In existing technologies, such as Figure 1 As shown, the coupled water supply system includes a fire truck 100 and a water supply truck 200. The water supply truck 200 is located behind the fire truck 100; the water supply truck 200 can be referred to as the rear truck, and the fire truck 100 as the front truck. The outlet of the water supply truck 200 is connected to the inlet of the fire truck 100 to provide fire water for various water output tests of the fire truck 100. The pressure at the outlet is generally below 0.6 MPa to ensure stable pressure delivery without damaging the water pump of the fire truck 100, thus forming a stable water supply system. However, the water supply capacity of the water supply truck 200 is limited; its maximum tank capacity does not exceed 25 tons. During water supply tests, it cannot provide sufficient water flow, preventing the water supply system from achieving high-flow, stable output and affecting the accuracy of the fire truck 100's tests.

[0054] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0055] This embodiment provides a fire truck water supply testing device for the water supply testing process of a fire truck, wherein the fire truck specifically refers to the fire truck to be tested described below. Figures 2-6 As shown, the fire truck water supply test device includes a water storage structure 1, a water supply circuit assembly 2, and a drive assembly 3. The water storage structure 1 is located outside the fire truck under test and is used to contain fire-fighting water. That is, the water storage structure 1 does not refer to the water tank on the fire truck under test, but rather a separately installed water storage structure 1 within the factory. One end of the water supply circuit assembly 2 is connected to the water storage structure 1, and the other end is used to connect to the fire truck under test (not shown in the figure). The drive assembly 3 is configured to transport the fire-fighting water in the water storage structure 1 to the fire truck under test through the water supply circuit assembly 2.

[0056] For example, the water storage structure 1 can be a water tank, a reservoir, etc. The water storage structure 1 can be a cuboid or cylindrical structure, or other regular or irregular structures. The water storage structure 1 is used to store fire-fighting water, and its volume is greater than 50 tons, for example, 50 tons, 80 tons, 100 tons, etc., to ensure that the fire truck under test has sufficient fire-fighting water for water supply tests or coupling tests. The fire-fighting water can be ordinary water, foam, or other fire-extinguishing agents with fire-extinguishing functions.

[0057] The water storage structure 1 is equipped with a liquid level sensor, which is used to detect the liquid level in the water storage structure 1. The liquid level sensor is electrically connected to the controller and the alarm. When the liquid level sensor detects that the actual liquid level in the water storage structure 1 is lower than the preset liquid level, it means that the liquid level in the water storage structure 1 is relatively low. The liquid level sensor transmits the low liquid level signal to the controller, and the controller controls the alarm to sound an alarm, so as to prompt the user to replenish the fire water in the water storage structure 1 in a timely manner.

[0058] The fire truck water supply testing device provided in this embodiment, compared with the existing water supply truck for supplying water to fire trucks, has a water storage structure 1 used to hold fire water, which can supply water to the fire truck under test for a long time and stably. The drive component 3 can transport the fire water in the water storage structure 1 to the fire truck under test through the water supply circuit component 2. When the fire truck under test is undergoing factory testing, the longer water supply duration and the greater the flow rate of fire water improve the accuracy of the performance testing of the fire truck under test.

[0059] If the water pressure output by the water supply component 2 to the fire truck under test is insufficient, it will affect the spray test results of the fire truck under test. Therefore, the fire truck water supply test device also includes a pressure stabilizer 4, which is connected to the water supply component 2 and is used to apply pressure to the water supply component 2.

[0060] If the actual pressure in the water supply circuit component 2 is lower than the preset pressure, for example, when the preset pressure is 0.5MPa, the pressure stabilizer 4 can automatically replenish the pressure, thereby ensuring the stability of the pressure of the entire water supply circuit component 2.

[0061] For example, the pressure regulator 4 may be a pressurizing drive source such as an air pump, which is connected to the water supply circuit component 2 and is used to pressurize the water supply circuit component 2.

[0062] For example, the pressure stabilizer 4 can also optionally be a diaphragm pressure tank, model SQL 1200×1.0, with a design pressure of 0.8MPa, a maximum working pressure of 1.0MPa, an effective volume of 600L, and a maximum working temperature of 50℃. Specifically, the diaphragm pressure tank includes a tank body and a flexible diaphragm. The flexible diaphragm is disposed inside the tank body, dividing the inner cavity of the tank body into two parts: a gas chamber and a liquid chamber. The gas chamber is used to fill with nitrogen or air, while the liquid chamber is connected to the water supply circuit assembly 2. When the pressure of the water supply circuit assembly 2 increases, the fire-fighting water in the water supply circuit assembly 2 is forced into the tank body of the diaphragm pressure tank, compressing the gas in the gas chamber; when the pressure of the water supply circuit assembly 2 decreases, the gas in the gas chamber expands, pushing the fire-fighting liquid in the tank body of the diaphragm pressure tank back into the water supply circuit assembly 2. The diaphragm pressure tank effectively absorbs pressure fluctuations through gas compression and expansion, thereby maintaining stable system pressure.

[0063] The following sections will provide a detailed introduction to each part of the water supply circuit component 2 and the drive component 3.

[0064] In one embodiment, such as Figures 2-6 As shown, the water supply system component 2 includes a first water supply pipeline 21 and a second water supply pipeline 22. The first water supply pipeline 21 is connected to the water storage structure 1 and the fire truck to be tested. The second water supply pipeline 22 is connected to the water storage structure 1 and the fire truck to be tested and is arranged parallel to and spaced apart from the first water supply pipeline 21.

[0065] Since the water storage structure 1 can store a large amount of fire water, the first water supply pipe 21 and the second water supply pipe 22 are branch pipes. The two water supply pipes, the first water supply pipe 21 and the second water supply pipe 22, can be used simultaneously to provide fire water to the fire truck to be tested, thereby increasing the flow of fire water and ensuring that the fire water supply to the fire truck to be tested is sufficient.

[0066] like Figures 2-6As shown, the water supply component 2 also includes a main pipe 23. One end of the main pipe 23 is connected to the first water supply pipe 21 and the second water supply pipe 22, and the other end is provided with a water supply port 231, which is used to connect to the fire truck to be tested. With this configuration, the main pipe 23 serves to converge the first water supply pipe 21 and the second water supply pipe 22, and the water supply port 231 is the connection joint between the water supply component 2 and the fire truck to be tested, so that the water supply component 2 can be connected to the fire truck to be tested through only one connection joint.

[0067] For example, the water supply inlet 231 and the water inlet of the fire truck to be tested can be detachably connected for easy installation and disassembly. For instance, the water supply inlet 231 and the water inlet of the fire truck to be tested can be connected by components such as flanges or connectors.

[0068] In one embodiment, the water supply assembly 2 further includes a control valve 24, which is disposed in at least one of the first water supply pipeline 21 and the second water supply pipeline 22. Exemplarily, both the first water supply pipeline 21 and the second water supply pipeline 22 are provided with a control valve 24, which is used to control the opening and closing of the corresponding water supply pipeline. The control valve 24 can be selected from at least one of a butterfly valve and a ball valve. Exemplarily, a butterfly valve and a ball valve are disposed on the first water supply pipeline 21, and also on the second water supply pipeline 22.

[0069] like Figures 2-6 As shown, the water supply assembly 2 also includes a check valve 25, which may be a one-way valve. The check valve 25 is provided in at least one of the first water supply pipeline 21 and the second water supply pipeline 22. For example, both the first water supply pipeline 21 and the second water supply pipeline 22 are provided with check valves 25. The check valves 25 are used to control the one-way flow of the corresponding water supply pipeline to prevent the backflow of fire-fighting water.

[0070] In one embodiment, the water supply circuit assembly 2 further includes a first pressure detection element 26, which may be a pressure gauge or a pressure sensor. The first pressure detection element 26 is disposed in the first water supply pipeline 21 and is used to detect the pressure in the first water supply pipeline 21 to prevent the pressure in the first water supply pipeline 21 from exceeding a reasonable range.

[0071] The water supply circuit assembly 2 also includes a second pressure detection element 27, which can be a pressure gauge or a pressure sensor. The second pressure detection element 27 is installed in the second water supply pipeline 22 to detect the pressure in the second water supply pipeline 22 and prevent the pressure in the second water supply pipeline 22 from exceeding the reasonable range.

[0072] In one embodiment, the water supply circuit assembly 2 further includes a third pressure detection element 29, which may be a pressure gauge, a pressure sensor, or a remote pressure gauge. The third pressure detection element 29 is disposed on the main pipeline 23 and is used to detect the pressure in the main pipeline 23 to prevent the pressure in the main pipeline 23 from exceeding a reasonable range.

[0073] The pressure stabilizer 4 is connected to the main pipeline 23. Since the fire water in the first water supply pipeline 21 and the second water supply pipeline 22 both flow into the main pipeline 23, the pressure in the main pipeline 23 is the pressure at which the fire water is delivered to the fire truck to be tested. By connecting the pressure stabilizer 4 to the main pipeline 23, the pressure of the fire water can be directly increased, ensuring that the fire water delivered to the fire truck to be tested has a certain flow rate and pressure, thereby improving the accuracy of the test.

[0074] For example, there are multiple pressure stabilizers 4, which are respectively disposed on both sides of the main pipeline 23 to ensure the stability of pressurization to the main pipeline 23. For example, there are four pressure stabilizers 4, which are respectively disposed on both sides of the main pipeline 23 and are staggered to avoid pressure impact and interference.

[0075] In one embodiment, such as Figures 2-6 As shown, the drive assembly 3 includes a variable frequency drive source 31 and a fixed frequency drive source 32. One of the variable frequency drive source 31 and the fixed frequency drive source 32 can transport the fire water in the water storage structure 1 to the fire truck to be tested through the first water supply pipeline 21, and the other can transport the fire water in the water storage structure 1 to the fire truck to be tested through the second water supply pipeline 22.

[0076] For example, the variable frequency drive source 31 includes a variable frequency motor and a variable frequency water pump. The output end of the variable frequency motor is connected to the variable frequency water pump to drive the variable frequency water pump to rotate. The variable frequency drive source 31 is installed on the first water supply pipeline 21, so that the fire water in the water storage structure 1 is delivered to the fire truck to be tested through the main pipeline 23 after passing through the first water supply pipeline 21.

[0077] For example, the fixed-frequency drive source 32 includes a fixed-frequency motor and a fixed-frequency water pump. The output end of the fixed-frequency motor is connected to the fixed-frequency water pump to drive the fixed-frequency water pump to rotate. The fixed-frequency drive source 32 is installed on the second water supply pipeline 22, so that the fire water in the water storage structure 1 is delivered to the fire truck to be tested through the main pipeline 23 after passing through the second water supply pipeline 22.

[0078] For example, the flow rates of the variable frequency pump and the fixed frequency pump are 540 cubic meters per hour, and these two pumps can reach over 1000 cubic meters per hour. The water supply test system formed by the water storage structure 1 and the two pumps has the advantages of stability, large flow rate, and good continuity. Utilizing the well-supplied water storage structure 1 and sufficient pumps to supply water to the fire truck under test can solve the problem of insufficient water supply during actual operation. For example, the fire truck under test can conduct a continuous water supply test for 1 hour.

[0079] In one embodiment, such as Figures 2-6 As shown, the water supply circuit assembly 2 also includes a shock absorber 28, which is disposed between one of the variable frequency drive source 31 and the fixed frequency drive source 32 and the first water supply pipeline 21; and / or, the shock absorber 28 is disposed between the other of the variable frequency drive source 31 and the fixed frequency drive source 32 and the second water supply pipeline 22.

[0080] For example, the shock absorber 28 is disposed between the variable frequency drive source 31 and the first water supply pipeline 21; the shock absorber 28 is also disposed between the fixed frequency drive source 32 and the second water supply pipeline 22.

[0081] For example, the damping component 28 can also be called a vibration damper throat, and the damping component 28 can be a bellows, a telescopic tube, etc. The bellows or telescopic tubes are usually used to absorb vibration, compensate for thermal expansion or displacement, so as to reduce the large vibration generated by the variable frequency drive source 31 and the fixed frequency drive source 32 during operation.

[0082] The fire truck water supply test device also includes an electrical control box 5, which is electrically connected to a frequency converter 31 and a fixed frequency converter 32. The electrical control box 5 mainly provides 380V power to power the entire system, enabling a stable water supply for extended periods. This is completely different from the traditional 24V power supply of fire trucks. By utilizing the voltage and power supply within the factory, a larger flow rate water pump can be configured, improving the stability of the entire fire truck water supply test device.

[0083] The fire truck water supply test device also includes a controller (not shown in the figure), which is electrically connected to the electrical control box 5, the first pressure detection element 26, the second pressure detection element 27, the third pressure detection element 29, the variable frequency drive source 31, and the fixed frequency drive source 32. It is understood that the fire truck water supply test device may also include a mobile control box, in which the first pressure detection element 26, the second pressure detection element 27, the third pressure detection element 29, the drive assembly 3, and the transmitter data of the fire truck under test can all be integrated.

[0084] Table 1 Comparison of Test Sites

[0085]

[0086] As can be seen from Table 1, when the water cannon flow rate of the fire truck under test remains unchanged, the water supply test device can effectively reduce the engine speed and water pump impeller speed of the fire truck under test, thus reducing the water supply burden and pressure of the fire truck under test.

[0087] Industrial water costs are high, and the large flow rate required for coupled water supply tests leads to significant waste, resulting in high testing costs. Therefore, such as... Figure 6 As shown, this embodiment also provides a recycling system, which includes a recycling device 10 and the above-mentioned fire truck water supply test device. The recycling device 10 is configured to receive the fire water sprayed by the fire truck and transport it to the water storage structure 1 of the fire truck water supply test device.

[0088] The recycling system provided in this embodiment allows the recycling device 10 and the fire truck to be tested to be positioned facing each other during the testing process. This allows the fire water sprayed by the fire truck to be directly sprayed into the recycling device 10 and collected. The fire water in the recycling device 10 is then re-injected into the water storage structure 1 of the fire truck water supply test device, thus achieving the recycling of fire water. This ensures the normal testing process of the fire truck while also saving water and reducing production costs.

[0089] Specifically, the recovery device 10 includes a water collection tank 101. The water storage structure 1 can be a cuboid or cylindrical structure, or other regular or irregular structures. The water storage structure 1 is used to store fire-fighting water sprayed from the fire truck to be tested. The water collection tank 101 is provided with an opening 1011, allowing fire-fighting water to enter the water storage structure 1 through the opening 1011.

[0090] Specifically, the recovery device 10 also includes a blocking member 102, which is disposed on the side of the water collection tank 101 facing the opening 1011. When the fire truck to be tested sprays water at the blocking member 102, the blocking member 102 can block most of the fire water and change the spray route of the fire water to recover the fire water into the water collection tank 101.

[0091] It is understandable that the blocking member 102 is rotatably connected to the water collection tank 101. The blocking member 102 can also function as a cover. The blocking member 102 can selectively cover the opening 1011 to realize the opening and closing of the opening 1011.

[0092] In one embodiment, the recovery device 10 further includes a recovery valve 103, which is disposed in the water collection tank 101. When the actual liquid level in the water collection tank 101 reaches the preset liquid level, the recovery valve 103 can be opened to facilitate the delivery of fire-fighting water in the water collection tank 101 to the water storage structure 1.

[0093] Specifically, the recovery valve 103 can be connected to the water storage structure 1 via a connecting pipe and driven by a water pump to transport the fire water in the collection tank 101 to the water storage structure 1 through the connecting pipe. Alternatively, the recovery valve 103 can be connected to other existing equipment with extraction functions. For example, the connecting pipe includes a first connecting pipe and a second connecting pipe. The recovery valve 103 can be connected to a water tanker or other fire truck via the first connecting pipe and connected to the water storage structure 1 via the second connecting pipe. By utilizing the pumping function of the water tanker or other fire truck, the fire water in the collection tank 101 can be transported to the water storage structure 1. This method uses locally sourced materials and has a relatively low modification cost.

[0094] In one embodiment, such as Figure 6 As shown, the recycling device 10 also includes a roller 104, which is located at the bottom of the water collection tank 101 and rotatably connected to the water collection tank 101 to facilitate the movement of the water collection tank 101.

[0095] In one embodiment, the recycling device 10 further includes a baffle assembly 105 disposed within the water collection tank 101. The baffle assembly 105 strengthens the inner wall of the water collection tank 101, preventing damage caused by long-term impact from high-pressure jets of fire-fighting water. Additionally, the baffle assembly 105 divides the inner cavity of the water collection tank 101 into multiple areas to meet various user needs. Specifically, the baffle assembly 105 includes multiple horizontal plates 1051 and multiple vertical plates 1052. The horizontal plates 1051 are arranged parallel and spaced apart, and the vertical plates 1052 are arranged parallel and spaced apart, with the horizontal plates 1051 and vertical plates 1052 perpendicular to each other.

[0096] Table 2 Comparison of Test Sites

[0097]

[0098] As shown in Table 2 above, when the engine speed of the fire truck under test remains constant, the outlet pressure of both the water cannon and the water pump of the fire truck under test will increase after water is supplied using the fire truck water supply test device, and the water outlet flow rate will also increase by approximately 11.43 L / s. Therefore, using the fire truck water supply test device can effectively increase pressure and flow, achieving the same effect as the fire truck water supply test device coupled with the vehicle's water supply. Furthermore, this fire truck water supply test device can completely replace external water supply vehicles and has a larger water storage structure, resulting in a larger water flow rate and more stable water pressure to maintain the water supply.
