[0002] The traditional fire hose is composed of an inner lining layer and a braided layer, and is mainly used to connect fire hoses and fire hydrants to achieve the purpose of delivering high-pressure water flow to extinguish fires. After the fire hose is produced, it needs to undergo wear detection to ensure the quality of the fire hose. However, in the existing wear detection process of the fire hose, it is usually only detected by friction or replacement of friction materials. However, when the fire hose is actually used, it is often necessary to face the influence of high temperature accompanied by fire, and the surface temperature of the ground after the fire source is extinguished is extremely high. After the fire hose contacts the ground after the fire source is extinguished, the fire hose will rub against the high-temperature ground.

DETAILED DESCRIPTION

[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention. Example 1

[0026] A fire-fighting equipment quality testing device, such as Figure 1-3 As shown, it includes a base frame 1, a detection box 2 and a conveying assembly; the base frame 1 is connected to the detection box 2, the detection box 2 is provided with a sewage outlet 2a, the detection box 2 is provided with a conveying outlet 2b; the detection box 2 is connected to the conveying assembly;

[0027] It also includes an electric push rod 5, an electric heating roller 6 and a grinding disc 7; two symmetrically arranged electric push rods 5 are bolted to the detection box 2; the telescopic ends of all the electric push rods 5 are fixedly connected to the electric heating roller 6; and six grinding discs 7 are connected to the electric heating roller 6.

[0028] The conveying assembly includes a conveying wheel 3, a conveying roller 8 and a first limit plate 9; two symmetrically arranged conveying wheels 3 are rotatably connected to the detection box 2; the conveying roller 8 is rotatably connected to the electric heating roller 6; and the first limit plate 9 is fixedly connected inside the detection box 2.

[0029] The grinding disc 7 and the electric heating roller 6 are arranged in a detachable structure, which is used to replace the grinding disc 7 of different materials to restore different conditions of the escalator.

[0030] It should be noted that the wear detection of the existing fire hose 4 after production is usually carried out only by friction or replacement of friction materials. However, when the fire hose 4 is actually used, it often needs to face the influence of high temperature accompanied by fire, and the surface temperature of the ground after the fire source is extinguished is extremely high. After the fire hose 4 contacts the ground after the fire source is extinguished, the fire hose 4 will rub against the high-temperature ground. In addition, when fighting a fire in a corridor, most of the escalators in the corridor are made of metal materials, that is, the escalator has strong thermal conductivity, and the heat of the escalator is higher than that of the ground. In the process of fire fighting, it is inevitable that the fire hose 4 will contact the escalator. Therefore, when testing the wear of the fire hose 4, only the friction coefficient of the fire hose 4 can be obtained, and it is impossible to know whether the quality of the fire hose 4 in actual use meets the requirements;

[0031] Therefore, when the quality inspection of the fire hose 4 is carried out, the staff first installs the fire equipment quality inspection device at the position where it is needed, and then uses the external conveying pipe to connect with the feed trough 107. Then the staff will hold the fire hose 4, first pass the fire hose 4 through the two conveying wheels 3, and then carry the fire hose 4 on the electric heating roller 6, and make the fire hose 4 contact with the conveying roller 8, and then support the fire hose 4 on the first limit plate 9, and then pass it through the conveying port 2b and fix it on the external conveying equipment, such as Figure 2As shown, water is then passed into the fire hose 4, and an external temperature detector is installed at the head nozzle of the fire hose 4 (the external temperature detector is located at one end of the fire hose 4 passing through the conveying port 2b) to detect the temperature of the water in the fire hose 4. Then the staff controls the electric heating roller 6 to operate to increase the temperature of the electric heating roller 6, that is, the heat of the electric heating roller 6 is transferred to the fire hose 4. Then the conveying wheel 3 and the external conveying equipment are controlled to drive the fire hose 4 to move. At the same time, the conveying roller 8 plays a guiding role to avoid excessive friction between the fire hose 4 and the edge of the installation part of the electric heating roller 6, which makes it difficult to move the fire hose 4. Then the two electric push rods 5 are controlled to cooperate with each other to drive the electric heating roller 6 to move back and forth, and the electric heating roller 6 drives the grinding disc 7 to move back and forth, that is, the grinding disc 7 and the fire hose 4 rub against each other (in actual use During use, the position where the fire hose 4 contacts the ground and the escalator will change as the fire hose 4 moves. Therefore, it is necessary to control the electric heating roller 6 to drive the grinding disc 7 to move back and forth so that the contact position of the fire hose 4 with the electric heating roller 6 and the grinding disc 7 changes. The grinding disc 7 is used to simulate the contact and friction between the fire hose 4 and the stair surface or the ground to simulate the fire hose 4 in the actual fire extinguishing scenario. The fire hose 4 contacts the high-temperature ground, and in the process where the electric push rod 5 cooperates with each other to drive the electric heating roller 6 to move back and forth, the electric heating roller 6 and the grinding disc 7 will contact the fire hose 4 alternately, and the fire hose 4 is driven to move by the conveying wheel 3 and the external conveying equipment, thereby simulating the scene where the fire hose 4 moves between the stair surface and the escalator during the fire extinguishing process, so that the detection of the fire hose 4 is closer to the actual fire extinguishing usage scenario.

[0032] When the two electric push rods 5 cooperate with each other to drive the electric heating roller 6 to move back and forth, the distance of the extension and contraction of the telescopic ends of the two electric push rods 5 can be controlled to prevent the grinding plate 7 from contacting the fire hose 4, simulating the scene in which the fire hose 4 only contacts the escalator during the fire extinguishing process. At the same time, the front electric push rod 5 can be controlled to move backward first, and the telescopic end of the rear electric push rod 5 can be adaptively contracted. Then, the distances of the extension and contraction of the telescopic ends of the two electric push rods 5 are the same, so that the electric heating roller 6 does not contact the fire hose 4, simulating the scene in which the fire hose 4 only contacts the stair surface or the ground during the fire extinguishing process.

[0033] When the conveying wheel 3 and the external conveying equipment drive the fire hose 4 to move, the infrared detector built into the conveying port 2b is used to determine whether the surface of the fire hose 4 is worn, cracked, has holes or is damaged. At the same time, the temperature detection device at the nozzle of the head of the fire hose 4 detects the temperature of the sprayed water to determine the thermal insulation performance of the fire hose 4. That is, in the above manner, the influence of the fire environment on the fire hose 4 when the fire hose 4 is actually used is simulated to know the actual quality of the fire hose 4 in the specific usage scenario. Example 2

[0034] On the basis of the above-mentioned embodiment 1, Figure 4-5 As shown, it also includes a cleaning plate 101; two symmetrically arranged cleaning plates 101 are fixedly connected inside the detection box 2, and the bristles on the cleaning plates 101 are in contact with the surface of the electric heating roller 6.

[0035] It also includes a cleaning component, which includes a telescopic airbag 102, an air intake plate 103, an exhaust pipe 104 and an air intake pipe 106; the detection box 2 and the electric heating roller 6 are detachably connected to two symmetrically arranged telescopic airbags 102; each telescopic airbag 102 is fixedly connected to two symmetrically arranged air intake plates 103, each air intake plate 103 is provided with eight annular array air intake holes, and a one-way valve is provided in the air intake hole of each air intake plate 103; each telescopic airbag 102 is connected to an exhaust pipe 104, and each exhaust pipe 104 is also provided with a one-way valve; the delivery port 2b is connected to the air intake pipe 106.

[0036] The detection box 2 further includes a cover 105 ; the cover 105 is fixedly connected to the inside of the detection box 2 , and the opening on the cover 105 is communicated with the delivery port 2 b ; the cover 105 is fixedly connected to the air inlet pipe 106 .

[0037] The cover 105 is configured to have an arc-shaped structure to prevent water and impurities from accumulating on the cover 105 .

[0038] The testing box 2 also includes a material feeding trough 107 . The testing box 2 is provided with a material feeding trough 107 .

[0039] In the process of testing the fire hose 4 in Example 1, the staff first uses an external delivery pipe to connect the exhaust pipe 104 and the intake pipe 106. Then, during the reciprocating movement of the electric heating roller 6 to perform quality testing on the fire hose 4, water and impurities such as dust are passed into the testing box 2 through the feed trough 107 through the external delivery pipe, so that the mixture of water and impurities contacts the fire hose 4, and part of the mixture of water and impurities adheres to the fire hose 4, so as to simulate the fire hose 4 in the process of extinguishing the fire, the fire hose 4 contacts the ground, and the fire hose 4 is adhered with water and impurities generated by the fire extinguishing, and then the water and impurities adhere to the fire hose 4. The fire hose 4 is in contact with the electric heating roller 6 and the grinding disc 7 to further restore the situation at the fire scene to ensure the accuracy of the detection results. It should be noted that the water and impurities attached to the fire hose 4 will increase the friction between it and the stairs and escalators, but in this process, too much water and impurities will be attached to the electric heating roller 6 and the grinding disc 7, that is, the two electric push rods 5 drive the electric heating roller 6 to move back and forth, so that the electric heating roller 6 contacts the bristles on the cleaning plate 101, and the bristles on the cleaning plate 101 are used to clean the water and impurities attached to the electric heating roller 6 during the friction of the fire hose 4, so as to avoid excessive impurities attached to the electric heating roller 6 affecting its thermal conductivity.

[0040] When the water attached to the fire hose 4 contacts the electric heating roller 6, that is, under the action of the electric heating roller 6, part of the water will vaporize and generate water vapor. When the electric push rod 5 drives the electric heating roller 6 to move back and forth, the electric heating roller 6 will squeeze and stretch the corresponding telescopic airbag 102. That is, when the electric heating roller 6 squeezes the telescopic airbag 102, the gas in the telescopic airbag 102 enters the air inlet pipe 106 through the exhaust pipe 104 and the external delivery pipe. When the electric heating roller 6 stretches the telescopic airbag 102, the water vapor generated around the electric heating roller 6 enters the telescopic airbag 102 through the air inlet plate 103. That is, when the telescopic airbag 102 is compressed later, the water vapor entering the telescopic airbag 102 will pass through the exhaust pipe 104 and the external delivery pipe. The pipe enters the air inlet pipe 106 and then is ejected through the delivery port 2b. The water vapor ejected from the delivery port 2b blows away the water and impurities remaining on the fire hose 4 to prevent the water and impurities on the fire hose 4 from affecting the detection of the infrared detector. At the same time, the water vapor is discharged through the telescopic airbag 102, the exhaust pipe 104 and the air inlet pipe 106 to prevent the water vapor from gradually accumulating in the detection box 2. The water vapor is easy to penetrate into the electrical equipment in the detection box 2, thereby preventing the electrical equipment in the detection box 2 from being damaged. It should be noted that a one-way valve is provided at the air inlet of the air inlet plate 103, so that the air inlet of the air inlet plate 103 can only take in air, and a one-way valve is also provided at the exhaust pipe 104, so that the exhaust pipe 104 can only exhaust air.

[0041] When the fire hose 4 is installed and passed through the conveying port 2b, the fire hose 4 contacts the cover 105, and the moisture and impurities on the fire hose 4 are first cleaned through the cover 105, so as to first reduce the moisture and impurities on the fire hose 4, and then the remaining water and impurities on the fire hose 4 are cleaned with the help of the water vapor sprayed from the conveying port 2b, which is beneficial to ensure the cleaning effect of the fire hose 4, and when the cover 105 first cleans the moisture and impurities on the fire hose 4, the cleaned water and impurities will be guided to the sewage outlet 2a through the guide part 2c, and the water and impurities discharged from the sewage outlet 2a are collected by placing a collection box under the sewage outlet 2a, thereby reducing the amount of impurities dropped on the ground when cleaning the moisture and impurities on the fire hose 4, and reducing the subsequent manual cleaning intensity.

[0042] At the same time, the water and impurities introduced into the detection box 2 from the feed trough 107 are guided to the sewage outlet 2a through the guide portion 2c, so as to prevent the water and impurities from accumulating in the detection box 2. Example 3

[0043] Based on the above embodiment 2, Figure 1-2 and Figure 6-7As shown, it also includes a detection component, which includes a first connecting plate 201, a spring limiting rod 202, a slider 203, an extrusion block 204, a second limiting plate 205, a second connecting plate 206 and an extrusion plate 207; four first connecting plates 201 distributed in a rectangular shape are fixedly connected inside the detection box 2; each first connecting plate 201 is fixedly connected to a spring limiting rod 202; the two spring limiting rods 202 on the same side are commonly connected to the slider 203; all the sliders 203 are slidably connected to the electric heating roller 6; the extrusion block 204 is fixedly connected to the electric heating roller 6; the second limiting plate 205 is slidably connected to all the spring limiting rods 202; the second limiting plate 205 is fixedly connected to the second connecting plate 206; the extrusion plate 207 is connected to the second connecting plate 206.

[0044] A detachable structure is provided between the second connecting plate 206 and the extrusion plate 207 for replacing different materials to simulate the friction test of different materials on the fire hose 4 .

[0045] When the quality of the fire hose 4 is tested, the electric heating roller 6 can be driven to move backward or forward by the two electric push rods 5, and the extrusion block 204 follows the electric heating roller 6 to move. In the process of the extrusion block 204 following the electric heating roller 6, the spring limiting rod 202 is limited by the first connecting plate 201, that is, the first connecting plate 201 remains stationary, that is, the electric heating roller 6 slides on the slider 203, and at the same time, the electric heating roller 6 drives the extrusion block 204 to move and squeeze the second limiting plate 205, so that the second limiting plate 205 slides on the limiting rod of the spring limiting rod 202 and compresses the corresponding spring, and then the second limiting plate 205 drives the second connecting plate 206 and the extrusion plate 207 to move downward, squeezing the fire hose 4 on the first limiting plate 9, so that the fire hose 4 generates friction with the extrusion plate 207 during the movement, and the extrusion plate 207 is normally tested for wear resistance, and the extrusion plate 207 can be removed and replaced with different materials, such as metal parts, glass, cement and other materials.
