Description

Technical Field

[0001] This utility model relates to the field of fire equipment testing technology, specifically a fire equipment testing and maintenance device. Background Technology

[0002] Fire equipment inspection and maintenance involves the regular inspection, testing, repair, and maintenance of fire equipment such as fire hydrants, fire extinguishers, and alarm systems. It covers performance parameter testing (such as fire hydrant water pressure), equipment integrity inspection, and troubleshooting and repair, ensuring that the equipment operates normally in emergencies and protecting fire safety. In the daily maintenance and safety inspection of fire facilities, the water pressure of fire hydrants is a key indicator for measuring their effectiveness in emergency situations such as fires.

[0003] However, traditional methods of monitoring the water pressure of fire hydrants often rely on manual operation using scattered testing tools carried to the site. These tools are often fragmented and prone to being lost or damaged during transport, which affects the normal operation of the monitoring work. To address these issues, the inventors have proposed a fire equipment testing and maintenance device. Utility Model Content

[0004] In order to solve the problem of easy testing of fire-fighting equipment, the purpose of this utility model is to provide a fire-fighting equipment testing and maintenance device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fire equipment testing and maintenance device, including a fire hydrant, a connector fixedly connected to the side of the fire hydrant, an installation head fixedly installed on one side of the connector, a stroke pipe communicating with the interior of the installation head fixedly connected to one side of the installation head, a U-shaped plate fixedly connected to the side of the stroke pipe away from the installation head, a pressure measuring component provided on the inner side of the U-shaped plate, the pressure measuring component being used to detect the water pressure of the fire hydrant, a reading component provided on the U-shaped plate, the reading component being used to read the deformation amount, and an adjustment component provided on one side of the pressure measuring component, the adjustment component being used to adjust the preload of the pressure measuring component.

[0006] Preferably, the pressure measuring assembly includes a fixed plate, which is fixedly connected to the inside of one side of the stroke tube. A telescopic rod is movably passed through the fixed plate. A piston plate is fixedly connected to one end of the telescopic rod. The piston plate is slidably engaged inside the stroke tube. A movable plate is movably sleeved on the outside of the telescopic rod. A spring is provided between the side of the movable plate away from the piston plate and the inner wall of the U-shaped plate. The spring is movably sleeved on the outside of the telescopic rod.

[0007] Preferably, the reading component includes a movable groove, which is formed at the top and bottom of the U-shaped plate. Two symmetrically distributed guide rods are fixedly connected to the side of the movable plate. The guide rods are slidably engaged in the movable groove. A pointer is fixedly connected to the ends of the two guide rods that are far apart from each other. A scale line is provided on the side of the U-shaped plate near the pointer. The position of the pointer corresponds to the position of the scale line.

[0008] Preferably, the adjusting assembly includes a threaded groove on the outside of the telescopic rod, an adjusting knob is rotatably connected to one side of the moving plate and threaded to the outside of the threaded groove, a spline is fixedly connected to the side of the telescopic rod, and a keyway is provided at one end of the U-shaped plate, with the spline slidingly engaged in the keyway.

[0009] Preferably, the side of the connector is fixedly connected to two arc-shaped plates that are centrally symmetrically distributed, and the side of the mounting head is fixedly connected to two locking blocks that are centrally symmetrically distributed. Each locking block has a locking groove on the side that is close to each other. The locking groove is movably locked in the arc-shaped plate, and the arc-shaped plate has a gradually changing trend from one end to the other.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Under the action of water pressure, the piston plate and telescopic rod are pushed to move towards one side of the spring, compressing the spring and causing the pointer to move horizontally along one side of the scale line. The horizontal displacement of the pointer is read using the scale line, which is the amount of spring compression. Finally, the pressure value is calculated according to Hooke's Law F=KX. The operation is simple and convenient, avoiding the reliance on manual carrying of scattered detection tools to the site. The detection tools are scattered, and parts are easily missed or damaged during the carrying process, which affects the normal operation of the monitoring work.

[0012] 2. By rotating the adjustment knob along the outside of the threaded groove, the moving plate is pushed to move towards the side of the spring, providing a certain preload to the piston plate. This reduces the horizontal displacement of the piston plate along the inside of the stroke tube when the water pressure is applied to the piston plate, preventing the piston plate from moving beyond its stroke.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-5 As shown, this utility model provides a fire equipment testing and maintenance device, including a fire hydrant 1, a connector 2 fixedly connected to the side of the fire hydrant 1, an installation head 3 fixedly installed on one side of the connector 2, a travel pipe 4 communicating with the inside of the installation head 3 fixedly connected to one side of the installation head 3, a U-shaped plate 5 fixedly connected to the side of the travel pipe 4 away from the installation head 3, a pressure measuring component 6 provided on the inner side of the U-shaped plate 5, the pressure measuring component 6 being used to detect the water pressure of the fire hydrant 1, a reading component 7 provided on the U-shaped plate 5, the reading component 7 being used to read the deformation amount, and an adjustment component 8 provided on one side of the pressure measuring component 6, the adjustment component 8 being used to adjust the preload of the pressure measuring component 6.

[0022] The pressure measuring assembly 6 includes a fixed plate 61, which is fixedly connected to the inside of one side of the stroke tube 4. A telescopic rod 63 is movably passed through the fixed plate 61. A piston plate 62 is fixedly connected to one end of the telescopic rod 63. The piston plate 62 is slidably engaged in the stroke tube 4. A movable plate 64 is movably sleeved on the outside of the telescopic rod 63. A spring 65 is provided between the side of the movable plate 64 away from the piston plate 62 and the inner wall of the U-shaped plate 5. The spring 65 is movably sleeved on the outside of the telescopic rod 63.

[0023] By adopting the above technical solution, when monitoring the water pressure of fire hydrant 1, the valve is opened to allow water to enter the interior of the installation head 3. Under the pushing action of water pressure, the piston plate 62 and the telescopic rod 63 are pushed to move towards the side of spring 65 and compress spring 65. Based on the compression of spring 65, the pressure value is calculated using Hooke's Law F=KX.

[0024] The reading assembly 7 includes a movable groove 71, which is formed at the top and bottom of the U-shaped plate 5. Two symmetrically distributed guide rods 72 are fixedly connected to the side of the movable plate 64. The guide rods 72 are slidably engaged in the movable groove 71. A pointer 73 is fixedly connected to the ends of the two guide rods 72 that are far apart from each other. A scale line 74 is provided on the side of the U-shaped plate 5 near the pointer 73. The positions of the pointer 73 and the scale line 74 correspond to each other.

[0025] By adopting the above technical solution, under the action of water pressure, the moving plate 64 is pushed to move to one side of the spring 65. The moving rod 72 is guided by the movable groove 71, thereby driving the pointer 73 to move horizontally along one side of the scale line 74. The horizontal displacement of the pointer 73 is read by the scale line 74, which is the compression amount of the spring 65.

[0026] The adjusting assembly 8 includes a threaded groove 81, which is located on the outside of the telescopic rod 63. An adjusting knob 82 is rotatably connected to one side of the movable plate 64, and the adjusting knob 82 is threadedly connected to the outside of the threaded groove 81.

[0027] By adopting the above technical solution, when the water pressure is too high and exceeds the stroke of the piston plate 62, the moving plate 64 can be moved to the side of the spring 65 by rotating the adjusting knob 82 along the outside of the threaded groove 81 in advance, so as to provide a certain preload to the piston plate 62. Thus, when the water pressure acts on the piston plate 62, the horizontal displacement of the piston plate 62 along the inside of the stroke tube 4 is reduced, and the movement of the piston plate 62 is prevented from exceeding the stroke.

[0028] A spline 84 is fixedly connected to the side of the telescopic rod 63, and a keyway 83 is opened at one end of the U-shaped plate 5. The spline 84 is slidably engaged in the keyway 83.

[0029] By adopting the above technical solution, the cooperation between the keyway 83 and the spline 84 facilitates the guidance of the movement of the telescopic rod 63, so that the telescopic rod 63 can always maintain horizontal movement.

[0030] Two centrally symmetrically distributed arc-shaped plates 11 are fixedly connected to the side of the connector 2, and two centrally symmetrically distributed snap-fit ​​blocks 9 are fixedly connected to the side of the mounting head 3. Each snap-fit ​​block 9 has a snap-fit ​​groove 10 on the side that is close to each other, and the snap-fit ​​groove 10 is movably snapped into the arc-shaped plate 11.

[0031] By adopting the above technical solution, when installing the mounting head 3 and the connector head 2, the slot 10 is engaged with the outside of the arc plate 11, thereby limiting the separation of the connector head 2 and the mounting head 3 and realizing the quick docking operation between the connector head 2 and the mounting head 3.

[0032] The curved plate 11 changes gradually from one end to the other.

[0033] By adopting the above technical solution, and by setting the arc plate 11 to gradually change from one end to the other, when the mounting head 3 rotates relative to the connecting head 2, it drives the slot 10 to move along the outer side of the arc plate 11. By utilizing the change in the width of the arc plate 11, the slot 10 can be tightly engaged with the arc plate 11, and the mounting head 3 moves towards one side of the connecting head 2, compressing the sealing ring between the connecting head 2 and the mounting head 3, thereby further improving the sealing performance of the connection between the connecting head 2 and the mounting head 3.

[0034] Working principle: When monitoring the water pressure of fire hydrant 1, the slot 10 is engaged with the outside of the arc plate 11, thereby limiting the separation of connector 2 and mounting head 3, and realizing the quick docking operation of connector 2 and mounting head 3. Then, the valve of fire hydrant 1 is opened, allowing water to enter the interior of mounting head 3. Under the pushing action of water pressure, piston plate 62 and telescopic rod 63 are pushed to move towards one side of spring 65, compressing spring 65. The movable groove 71 guides the movement of guide rod 72, thereby driving pointer 73 to move horizontally along one side of scale line 74. The horizontal displacement of pointer 73 is read using scale line 74, which is the compression of spring 65. Finally, the pressure value is calculated according to Hooke's Law F=KX.

[0035] Meanwhile, when the water pressure exceeds the stroke of the piston plate 62, the moving plate 64 can be moved toward the side of the spring 65 by rotating the adjusting knob 82 along the outside of the threaded groove 81 in advance, so as to provide a certain preload to the piston plate 62. This reduces the horizontal displacement of the piston plate 62 along the inside of the stroke tube 4 when the water pressure is applied to the piston plate 62, and prevents the piston plate 62 from moving beyond its stroke.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
