DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] See also Figure 1-3 A detection device for a fire pump comprises a first baffle plate 1, wherein the center of one side wall of the first baffle plate 1 is fixedly connected to the tail end of a hydraulic mechanism 2, the output end of the hydraulic mechanism 2 is fixedly connected to the corner of a drain pipe 3, the side wall of the drain pipe 3 is connected with a pressure gauge 4, the starting end of the drain pipe 3 is fixedly connected to one side of the center of a movable plate 5, the other side of the movable plate 5 is fixedly connected with a water outlet pipe interface 6 corresponding to the position of the drain pipe 3, support blocks 18 are symmetrically arranged at the lower part of both sides of the water outlet pipe interface 6, the bottom of the support block 18 is fixedly connected to one side of the top of a slider 17, the bottom of the slider 17 is slidably connected with a support plate 10, one side of the support plate 10 is fixedly connected to the side wall of the movable plate 5, the The outer wall of the support plate 10 is fixed to one end of the L-shaped block 11, and the side wall of the other end of the L-shaped block 11 is rotatably connected to one end of the screw rod 14. The other end of the screw rod 14 is threadedly connected in sequence and passes through the round through hole 1701 of the symmetrically arranged slider 17 and is rotatably connected to the side wall of the L-shaped block 11 on the other side. One end of the screw rod 14 passes through the L-shaped block 11 and is fixedly connected to the turning handle 12. The four corners of the first baffle plate 1 are fixed to one end of the limiting column 9. The other end of the limiting column 9 slides through the four corners of the movable plate 5 and is fixedly connected to the four corners of the second baffle plate 8. The center of the inner wall of the second baffle plate 8 is fixedly connected to the water inlet pipe interface 7. The lower parts of both sides of the water inlet pipe interface 7 are arranged with the same structure as the water outlet pipe interface 6.

[0019] Among them, the support block 18 is symmetrically and obliquely installed in an inverted eight shape, and multiple groups of rollers 1801 are rotatably connected to the oblique side surfaces of the support block 18. A drainage hole 1802 is provided at the bottom end of the installation groove of the roller 1801. By arranging the roller 1801, the sliding friction is converted into rolling friction, thereby reducing the wear when the interface of the fire pump contacts the support block 18. At the same time, during the inspection, it is inevitable that test water enters the installation groove of the roller 1801 and affects the rolling of the roller 1801.

[0020] Among them, an L-shaped through hole 1702 is provided above the circular through hole 1701 of the slider 17, and the L-shaped through hole 1702 is penetrated by a water baffle 19 for non-contact matching connection. Both ends of the water baffle 19 are respectively fixed to the L-shaped block 11. By providing the water baffle 19, the test water can be prevented from splashing onto the screw rod 14 and corroding the screw rod 14, thereby improving the service life.

[0021] Among them, the two sides of the bottom end of the slider 17 are slidably connected to the T-shaped groove 1002 opened on the bottom surface of the support plate 10 through symmetrically arranged corner T-shaped structures 1703. One side of the corner T-shaped structure 1703 needs to pass through the through hole groove 1001 opened on the support plate 10 and be slidably connected to the support plate 10. The T-shaped groove 1002 set at the bottom can prevent test water from entering the T-shaped groove 1002 and causing corrosion to affect the service life.

[0022] The screw rod 14 is a symmetrically fixed structure of a left-hand screw rod and a right-hand screw rod, so as to realize the reverse movement of two symmetrical sliders 17 .

[0023] Among them, the end of the screw rod 14 close to the turning handle 12 is threadedly connected to one end of the movable ruler 15, and the other end of the movable ruler 15 is slidably clamped in the inside of the circular ruler frame 16. The upper part of the outer side of the circular ruler frame 16 is provided with a scale 1601. The scale 1601 is determined by the matching displacement of the screw rod 14 and the movable ruler 15 and the rotational lateral displacement of the screw rod 14 and the slider 17, and then according to different fire pump interface sizes, the distance between the two support blocks 18 is adjusted by observing the scale 1601.

[0024] Working principle: First, according to the diameter of the fire pump connector, manually turn the handle 12, and then the screw 14 rotates accordingly, and then the movable ruler 15 moves accordingly, and the other end of the movable ruler 15 is displaced in the circular ruler frame 16, and the diameter of the corresponding fire pump is determined by observing the alignment value of the scale 1601 on the movable ruler 15 and the circular ruler frame 16. At the same time, the corner T-shaped structure 1703 at the lower end of the slider 17 slides along the T-shaped groove 1002, and then the distance between the two support blocks 18 follows the change to match the center position of the connector of the fire pump is always aligned with the center of the outlet pipe interface 6 and the inlet pipe interface 7. Then, the interfaces on both sides of the fire pump are hoisted onto the support block 18 by driving, and then the hydraulic mechanism 2 is started to push the movable plate 5 to move and clamp the fire pump. At the same time, the interfaces at both ends of the fire pump move on the surface of the support block 18, thereby driving the roller 1801 to roll, and finally, the test water is introduced to observe the value of the pressure gauge 4 to complete the detection of the fire pump.
