Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, specifically to a mechanical emergency starting device for a high-pressure fire pump starter cabinet. Background Technology

[0002] According to fire safety specifications, high-pressure fire pumps are automatically started via relays. However, if a relay or weak current signal malfunction prevents the fire pump from starting automatically, the fire pump should be started directly using the "mechanical emergency start device" installed in the fire pump control cabinet. This "mechanical emergency start device" is a device that directly starts the fire pump through a mechanical interlocking device. Normally, its start handle is in a stopped state, and it must be forcibly started by the appropriate management personnel in case of an emergency fire.

[0003] A search revealed an existing patent (publication number: CN212028149U) disclosing a mechanical emergency starting device for a fire pump, comprising a base, a rotating shaft, and a drive shaft. One end of the drive shaft has a connecting end. The base has a mounting groove for the drive shaft to rotate and be fitted into. The connecting end of the drive shaft extends out of the base and has a retaining ring. A fixing ring is located at the end of the base near the retaining ring. The rotating shaft is fixed to the connecting end. The end face of the drive shaft has an inwardly recessed V-shaped groove. A propulsion shaft is also located within the mounting groove. The end face of the propulsion shaft has a V-shaped protrusion, and the other end has a push rod. The propulsion shaft has two limiting posts. The base has two elongated holes through which the limiting posts of the propulsion shaft pass. One end of the base has two fixing posts, and an elastic element is provided between the fixing posts and the limiting posts. This invention's starting device allows for direct starting of the fire pump by rotating the rotating shaft when the fire pump cannot be started through the control center, reducing the loss of life and property caused by the inability to start the fire pump in a timely manner for firefighting operations.

[0004] However, in the existing technologies, some require opening the cabinet door to operate the mechanical emergency start device, which is inconvenient. Others, although located outside the cabinet, pose a risk of misoperation and are not easy to lock during use, making them inconvenient to use.

[0005] In view of this, the present invention proposes a mechanical emergency starting device for a high-pressure fire pump starter cabinet. Utility Model Content

[0006] This utility model proposes a mechanical emergency starting device for a high-pressure fire pump starter cabinet, which solves the problems of inconvenience in preventing accidental activation and inconvenience in self-locking in related technologies.

[0007] The technical solution of this utility model is as follows: A mechanical emergency starting device for a high-pressure fire pump starter cabinet includes a cabinet door; a mechanical emergency starting device body disposed on the back of the cabinet door, a fixed cylinder fixedly connected to the cabinet door; a sliding groove opened on one side of the fixed cylinder, a fixed groove being opened inside the fixed cylinder on one side of the sliding groove, a movable seat slidably connected inside the fixed groove, one end of the movable seat extending into the sliding groove and fixedly connected to a sliding plate, a connecting rod extending to the outside of the sliding groove being fixedly connected to one side of the sliding plate, a return spring being wound inside the sliding groove on the surface of the connecting rod, and a connecting seat being fixedly connected to one end of the connecting rod; a self-locking component assembled on the fixed cylinder, the self-locking component being used to achieve limit self-locking after the movable seat is pushed; a fixed handle fixedly connected to one end of the movable seat, a sliding handle being disposed on one side of the fixed handle; a fixing component assembled on the fixed handle and the sliding handle, the fixing component being used to achieve limit fixation after the sliding handle slides.

[0008] The self-locking assembly includes: a reserved groove formed on one side of the top wall of the fixed groove, a limiting block extending to the outside of the fixed groove being slidably connected inside the reserved groove, a pull rod extending to the outside of the fixed cylinder being fixedly connected to the top of the limiting block, and a pull ring being fixedly connected to the top of the pull rod; a fixing spring wrapped around the surface of the pull rod, the two ends of the fixing spring being fixedly connected to the top wall of the reserved groove and the bottom end of the limiting block, respectively; and a limiting ring groove formed annularly on one side of the surface of the movable seat.

[0009] Preferably, the pull ring has an O-groove, and the bottom end of the pull ring and the top end of the pull rod are welded together as an integral structure.

[0010] Preferably, the inner wall of the reserved groove is provided with a sliding groove, and the top two sides of the limiting block are fixedly connected with sliders that slide in cooperation with the inside of the sliding groove.

[0011] Preferably, the lower end of one side of the limiting block is arc-shaped, and the side of the movable seat near the limiting block is arc-shaped.

[0012] Preferably, the limiting ring groove is O-shaped, and the width inside the limiting ring groove is greater than the width of the limiting block.

[0013] Preferably, the fixing component includes: an adjustment groove formed inside one side of the sliding handle, and an adjustment bolt extending into the adjustment groove is movably connected to one side of the front of the sliding handle; and an adjustment plate fixedly connected to one side of the fixed handle, wherein bolt holes that are threadedly engaged with one end of the adjustment bolt are equally spaced on the front of the adjustment plate.

[0014] Preferably, the adjusting plate and the interior of the adjusting groove form a sliding structure, and the adjusting plate and the adjusting groove are I-shaped.

[0015] Preferably, the surface of the adjusting bolt nut is provided with anti-slip textures at equal angles, and the anti-slip textures are arc-shaped.

[0016] Preferably, the top of the sliding handle has a finger groove, and the finger groove is wavy in shape.

[0017] The beneficial effects of this utility model are as follows:

[0018] In this invention, pushing the fixed handle causes the movable seat to slide. When one side of the movable seat contacts the limiting block, the arc shape of the limiting block and one side of the movable seat allows the limiting block to rise directly without obstructing the pushing of the movable seat. When the movable seat is fully pushed in, the elastic force of the fixed spring causes the limiting block to descend into the limiting ring groove, thereby achieving self-locking of the movable seat and preventing the movable seat from returning to its original position after being released, which would cause the connecting seat to disengage from the drive rod of the mechanical emergency start device body. At the same time, when it is not necessary to manually start the high-pressure fire pump, the pull ring can be pulled to make the limiting block rise into the reserved groove, and then the elastic force of the return spring can be used to make the movable seat slide back to its original position. Thus, when starting the mechanical emergency start device body, it is necessary to push and then rotate, avoiding accidental operation caused by rotating the fixed handle and the sliding handle, and improving its practicality.

[0019] In this invention, after the sliding handle is pulled to a suitable length, the adjusting bolt is tightened to screw it into the appropriate bolt hole. This allows the overall length of the fixed handle, adjusting plate, and sliding handle to be changed, so that it can be adjusted according to the space of the high-pressure fire pump starter cabinet. That is, when the space is sufficient to allow the sliding handle to slide a longer distance, it is also more convenient and less strenuous for the staff to rotate the drive rod on the mechanical emergency starter body.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0028] A preferred embodiment of the mechanical emergency starting device for the high-pressure fire pump starter cabinet provided by this utility model is, for example... Figures 1 to 5 The diagram shows a mechanical emergency starting device for a high-pressure fire pump starter cabinet, comprising a cabinet door 1; a mechanical emergency starting device body 6 disposed on the back of the cabinet door 1, with a fixed cylinder 7 fixedly connected to the cabinet door 1; a sliding groove 11 formed on one side of the fixed cylinder 7, with a fixed groove 13 formed inside the fixed cylinder 7 on one side of the sliding groove 11, a movable seat 14 slidably connected inside the fixed groove 13, one end of the movable seat 14 extending into the sliding groove 11 and fixedly connected to a sliding plate 12, a connecting rod 9 extending to the outside of the sliding groove 11 fixedly connected to one side of the sliding plate 12, a return spring 10 wound inside the sliding groove 11 on the surface of the connecting rod 9, and a connecting seat 8 fixedly connected to one end of the connecting rod 9; a self-locking component 2 assembled on the fixed cylinder 7, the self-locking component 2 being used to achieve limit self-locking after the movable seat 14 is pushed; a fixed handle 3 fixedly connected to one end of the movable seat 14, with a sliding handle 5 provided on one side of the fixed handle 3; and a fixing component 4 assembled on the fixed handle 3 and the sliding handle 5, the fixing component 4 being used to achieve limit fixation after the sliding handle 5 slides.

[0029] The self-locking assembly 2 includes: a reserved groove 203 formed on one side of the top wall of the fixed groove 13, a limiting block 206 extending to the outside of the fixed groove 13 is slidably connected inside the reserved groove 203, a pull rod 202 extending to the outside of the fixed cylinder 7 is fixedly connected to the top of the limiting block 206, and a pull ring 201 is fixedly connected to the top of the pull rod 202; a fixing spring 208 wrapped around the surface of the pull rod 202, the two ends of the fixing spring 208 being fixedly connected to the top wall of the reserved groove 203 and the bottom end of the limiting block 206 respectively; and a limiting ring groove 207 formed annularly on one side of the surface of the movable seat 14.

[0030] In this embodiment, after the fixed handle 3 is pushed to drive the movable seat 14 to slide until it engages with the drive rod on the connecting seat 8 and the mechanical emergency start device body 6, the elastic force of the fixed spring 208 can be used to make the limiting block 206 descend into the limiting ring groove 207, thereby realizing the self-locking of the movable seat 14. At the same time, the shape and width of the limiting ring groove 207 will not hinder the rotation of the movable seat 14, which facilitates the subsequent rotation action.

[0031] In a further preferred embodiment of the present invention, an O-groove is provided on the pull ring 201, and the bottom end of the pull ring 201 and the top end of the pull rod 202 are welded together as an integral structure.

[0032] In this embodiment, a pull ring 201 with an O-shaped groove is used to facilitate the operation of the pull rod 202 by the operator.

[0033] In a further preferred embodiment of the present invention, a sliding groove 204 is provided on the inner wall of the reserved groove 203, and sliders 205 that slide and cooperate with the inside of the sliding groove 204 are fixedly connected to the top of both sides of the limiting block 206.

[0034] In this embodiment, the sliding of the slider 205 and the inside of the groove 204 makes the up-and-down sliding of the limiting block 206 more stable.

[0035] In a further preferred embodiment of the present invention, the lower end of one side of the limiting block 206 is arc-shaped, and the side of the movable seat 14 near the limiting block 206 is arc-shaped.

[0036] In this embodiment, the shape of the limiting block 206 and one side of the movable seat 14 is utilized so that the movable seat 14 can be directly pushed to engage the connecting seat 8 with the drive rod on the mechanical emergency start device body 6.

[0037] In a further preferred embodiment of the present invention, the limiting annular groove 207 is O-shaped, and the width inside the limiting annular groove 207 is greater than the width of the limiting block 206.

[0038] In this embodiment, the use of a wider and O-shaped limiting ring groove 207 ensures that the smooth rotation of the movable seat 14 is not affected by the large friction between the surface of the limiting block 206 and the inner wall of the limiting ring groove 207 when the movable seat 14 rotates. Example

[0039] Based on Embodiment 1, a preferred embodiment of the mechanical emergency starting device for the high-pressure fire pump starter cabinet provided by this utility model is, for example... Figures 1 to 5 As shown: The fixing component 4 includes: an adjustment groove 403 opened inside one side of the sliding handle 5, and an adjustment bolt 404 extending into the adjustment groove 403 is movably connected to one side of the front of the sliding handle 5; an adjustment plate 402 fixedly connected to one side of the fixing handle 3, and bolt holes 401 that are threadedly engaged with one end of the adjustment bolt 404 are opened at equal intervals on the front of the adjustment plate 402.

[0040] In this embodiment, after the sliding handle 5 is pulled to a suitable length, the adjusting bolt 404 is tightened so that it is screwed into the suitable bolt hole 401. This allows the overall length of the fixed handle 3, the adjusting plate 402, and the sliding handle 5 to be changed, so that it can be adjusted according to the space of the high-pressure fire pump starter cabinet.

[0041] In a further preferred embodiment of the present invention, a sliding structure is formed between the interior of the adjusting plate 402 and the adjusting groove 403, and the shapes of the adjusting plate 402 and the adjusting groove 403 are I-shaped.

[0042] In this embodiment, the smoothness of sliding of the sliding handle 5 is improved by utilizing the sliding between the I-shaped adjusting plate 402 and the inside of the adjusting groove 403.

[0043] In a further preferred embodiment of the present invention, the surface of the adjusting bolt 404 nut is provided with anti-slip textures 405 at equal angles, and the shape of the anti-slip textures 405 is arc-shaped.

[0044] In this embodiment, the arc-shaped anti-slip texture 405 is used to increase the friction when the operator's fingers rotate the adjusting bolt 404 nut, and a hexagonal groove is provided on one side of the adjusting bolt 404 nut to facilitate rotation with a hexagonal wrench when rotation is inconvenient.

[0045] In a further preferred embodiment of the present invention, a finger groove 15 is provided at the top of the sliding handle 5, and the finger groove 15 is wavy in shape.

[0046] In this embodiment, the wave-shaped finger groove 15 is used to facilitate the operator to hold the sliding handle 5 and rotate it.

[0047] The working principle of this utility model is as follows: First, install the mechanical emergency start device body 6 at a suitable position in the high-pressure fire pump starter cabinet and connect the wires. Then, install the fixing cylinder 7 on the cabinet door 1, so that the connecting seat 8 is coaxial with the drive rod on the mechanical emergency start device body 6. Then, adjust according to the external space of the high-pressure fire pump starter cabinet. At this time, loosen the adjusting bolt 404 until it is completely disengaged from the bolt hole 401. Then, pull the sliding handle 5 to slide to a suitable length, and then tighten the adjusting bolt 404 so that it is screwed into the suitable bolt hole 401. This can change the overall length of the fixing handle 3, the adjusting plate 402 and the sliding handle 5, so that it can be adjusted according to the space of the high-pressure fire pump starter cabinet. That is, when the space is sufficient for the sliding handle 5 to slide longer, it is more convenient and less strenuous for the staff to rotate the drive rod on the mechanical emergency start device body 6.

[0048] Then, when manual start is required, the fixed handle 3 can be pushed to slide the movable seat 14. When one side of the movable seat 14 contacts the limiting block 206, the limiting block 206 will rise, causing the pull rod 202 to slide upward and compress the fixed spring 208. After the movable seat 14 is fully pushed in, the elastic force of the fixed spring 208 can be used to make the limiting block 206 descend into the limiting ring groove 207. The limiting ring groove 207 is relatively wide and O-shaped, so that after the movable seat 14 rotates, the limiting block 206 and the limiting ring groove 207 slide relative to each other, thereby realizing the movement of the movable seat. The push of 14 is self-locking and will not hinder the rotation of the movable seat 14. At this time, the connecting seat 8 will be locked onto the drive rod on the mechanical emergency start device body 6. Then the sliding handle 5 can be rotated to make the fixed handle 3 and the movable seat 14 rotate, thereby driving the sliding plate 12, the connecting rod 9 and the connecting seat 8 to rotate, causing the drive rod on the mechanical emergency start device body 6 to rotate, realizing the action of forcibly starting the electric fire pump. Furthermore, the return spring 10 is not fixed to one end of the sliding plate 12, so the return spring 10 will not rotate when the connecting rod 9 and the sliding plate 12 rotate.

[0049] Meanwhile, when the high-pressure fire pump does not need to be manually started, the pull ring 201 can be pulled to raise the pull rod 202, causing the limit block 206 to rise into the reserved slot 203. Then, the elastic force of the return spring 10 is used to make the movable seat 14 slide back to its original position. The push and rotation steps prevent the operator from accidentally turning the sliding handle 5 directly. When not in use, the connecting seat 8 is separated from the drive rod on the mechanical emergency start device body 6, so that the opening or closing of the cabinet door 1 is not obstructed. The fixed handle 3 and the sliding handle 5 are outside the cabinet door 1, so the electric fire pump can be started in an emergency without opening the cabinet door 1.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
