DETAILED DESCRIPTION

[0016] like Figures 1 to 12 As shown, the present invention comprises a base 1, a water spraying mechanism and an energy storage mechanism. The structure and working principle of the present invention are described in detail below in conjunction with the accompanying drawings.

[0017] like Figures 1 to 12 As shown, a high-voltage electrical fire sprinkler device comprises a base 1, a water spraying mechanism and an energy storage mechanism. The water spraying mechanism is located at one end of the base 1. Figure 4 As shown, the water spray mechanism includes a cylinder 4, an energy storage spring 41, a piston 45 and a piston rod 42. Figure 1 , Figure 3As shown, both ends of the cylinder 4 are fixedly connected to the base 1 through cylinder fixing members 44, as shown in FIG. Figure 4 As shown, both ends of the cylinder 4 are open, one end of the cylinder 4 is a water outlet 47, a piston 45 is slidably arranged inside the cylinder 4, one end of the piston rod 42 is fixedly connected to the piston 45, the other end of the piston rod 42 extends out of the cylinder 4 through the other end of the cylinder 4, and an energy storage spring 41 is arranged between the piston 45 and the other end of the cylinder 4. In a natural state, under the action of the energy storage spring 41, the distance between the piston 45 and the other end of the cylinder 4 is the maximum. A water storage chamber is formed between the piston 45 and the water outlet 47, and the side wall of the cylinder 4 has a one-way valve 43 connected to the water storage chamber. The setting of the one-way valve 43 allows water to enter the water storage chamber through the one-way valve 43, but cannot flow out of the water storage chamber through the one-way valve 43. The energy storage mechanism is located at the other end of the base 1. The energy storage mechanism compresses the energy storage spring 41 to store energy by pulling the piston rod 42 toward the side away from the water outlet 47. After the energy storage mechanism releases the piston rod 42, the energy storage spring 41 releases elastic potential energy to spray the water in the water storage chamber through the water outlet 47, thereby achieving live cleaning of the electrical equipment. In order to achieve one-way blocking of the water outlet 47, a duckbill valve 48 is provided in the water outlet 47, and when the energy storage spring 41 stores energy, a negative pressure is formed by the setting of the duckbill valve 48, so that the external water enters the water storage chamber through the one-way valve 43. The present invention provides two embodiments of the energy storage mechanism, and the three implementation methods of the energy storage mechanism are described separately below.

[0018] Embodiment 1: like Figures 1 to 4 As shown, the energy storage mechanism includes a reducer 2, a motor 3, a rack 5 and a gear 51. The reducer 2 is fixed on the base 1, the motor 3 is fixed on the top of the reducer 2, the output end of the motor 3 is connected to the input shaft of the reducer 2, the gear 5 is fixed on the output shaft 21 of the reducer 2, the gear 5 is an incomplete gear, the rack 51 is slidably arranged on the base 1 and is used to mesh with the gear 5, and the other end of the piston rod 42 is fixedly connected to the rack 51. After starting the motor 3, the rotational motion output by the motor 3 is transmitted to the gear 5 after being decelerated by the reducer 2, so that the gear 5 rotates clockwise. During the rotation of the gear 5, the teeth on the gear 5 mesh with the rack 51, driving the rack 51 to move to the left, that is, to move away from the side of the cylinder 4. At this time, the piston 45 moves to the left in the cylinder 4, and the volume of the water storage chamber becomes larger to generate negative pressure, and water is sucked in through the one-way valve 43. At this time, the energy storage spring 41 stores energy. When the teeth on the gear 5 are no longer meshed with the rack 51 , the energy storage spring 41 releases its elastic potential energy, and the water in the water storage chamber is discharged through the water outlet 47 to perform the cleaning operation.

[0019] To facilitate assembly, Figure 4As shown, the other end of the piston rod 42 extends into the rack 51, and the other end of the piston rod 42 is threadedly connected to the rack 51, thereby achieving a fixed connection between the piston rod 42 and the rack 51. The threaded connection between the piston rod 42 and the rack 51 facilitates adjustment of the relative position between the two. Of course, the piston rod 42 can also be welded to the rack 51. Figures 2 to 4 As shown, a slider 53 is fixed to the bottom of the rack 51, and a guide rail 52 is fixed to the base 1. The slider 53 is slidably connected to the guide rail 52, thereby realizing the sliding connection between the rack 51 and the base 1. A square steel 12 is provided at the bottom of the base 1 to facilitate the installation and fixation of the base 1.

[0020] Embodiment 2: like Figures 5 to 8 As shown, the energy storage mechanism includes a cylinder 54 and a claw 57. The two ends of the cylinder 54 are fixedly connected to the base 1 through a cylinder fixing member 55. The claw 57 is located on the top rod 541 of the cylinder 54 and moves with the extension and retraction of the top rod 541. When the top rod 541 is extended to the maximum stroke, the claw 57 clamps the other end of the piston rod 42. During the retraction of the top rod 541, the piston rod 42 moves with the top rod 541 to compress the energy storage spring 41 and store energy. When the top rod 541 is retracted to the origin, the claw 57 releases the piston rod 42. After the cylinder 54 is started, the top rod 541 of the cylinder 54 is retracted. While the claw 57 at the end of the top rod 541 grabs the piston rod 42, it pulls the piston rod 42 to the left, and then pulls the piston 45 to move to the left in the cylinder 4. At this time, the volume of the water storage chamber increases and negative pressure is generated, and then water is sucked in through the one-way valve 43. At this time, the energy storage spring 41 is compressed and stores energy. When the push rod 541 retracts to the original position, the claw 57 releases the piston rod 42 , and the energy storage spring 41 releases its elastic potential energy to discharge the water in the water storage chamber through the water outlet 47 .

[0021] The claw 57 can also be an electric claw, and travel switches are respectively set at the starting point and the end point of the travel of the push rod 541. When the claw 57 touches the travel switch at the end point, the claw 57 grabs the piston rod 42; when the claw 57 touches the travel switch at the starting point, the claw 57 releases the piston rod.

[0022] To facilitate assembly, Figure 8As shown, a connecting plate 58 is fixed to the end of the push rod 541, and the connecting plate 58 is slidably connected to the base 1, and the claw 57 is located on the connecting plate 58. Specifically, the connecting plate 58 has a plurality of claw connection ends 581, and the claw 57 is hingedly connected to the claw connection end 581 and a pre-tightening member is provided between the two. One end of the claw 57 is a clamping end 572, and the pre-tightening member acts to clamp the other end of the piston rod 42 in a natural state. The other end of the claw 57 is a driving end 571, and the base 1 has a driving member for squeezing the driving end 571. At the end of the retraction process of the push rod 541, the driving member squeezes the driving end 571 of the claw 57 so that the driving ends 571 are close to each other, and the clamping ends 572 are away from each other under the action of the lever principle. At this time, the clamping end 572 gradually opens until the piston rod 42 is released. The other end of the piston rod 42 has a conical baffle 45, and a transition surface is provided between the large end and the small end of the baffle 45. The large end of the baffle 45 is fixedly connected to the piston rod 42, and the small end of the baffle 45 faces the ejector rod 541. During the extension of the ejector rod 541, the clamping end 572 moves along the transition surface until the baffle 45 is surrounded by the clamping end 572. Figure 5 to Figure 6 As shown, the driving member is a shrink sleeve 56, and the driving member has a circular hole 561. The claw 57 squeezes the driving end 571 against the inner wall of the circular hole 561 during the process of the ejector rod 541 retracting, and the side of the driving end 571 that contacts the circular hole 561 is an inclined surface 574. During the process of the driving end 571 gradually moving along the axial direction of the circular hole 561 relative to the driving member 56, the inclined surface 574 moves relative to the inner wall of the circular hole 561, and then the degree of squeezing of the driving end 571 by the driving member 56 gradually increases, the opening degree of several driving ends 571 gradually decreases, the contraction degree gradually increases, and the opening degree of the clamping end 572 gradually increases until the clamping end 572 separates from the baffle 45 and releases the baffle 45 and the piston rod 42. The claw 57 has a mounting member 573, and the mounting member 573 is hingedly connected to the claw connection end 581, thereby realizing the hinge connection between the claw 57 and the claw connection end 581. In the embodiment of the present invention, three claw connection ends 581 are provided on the connection plate 58, and three claws 57 are provided. The connection plate 58 is fixed on the slider 53, and the guide rail 52 is fixed on the base 1. The slider 53 is slidably connected to the guide rail 52, thereby realizing the sliding connection between the connection plate 58 and the base 1.

[0023] Embodiment three: like Figures 9 to 12 As shown, the energy storage mechanism includes a driving wheel 22 and a shifting block 6. The driving wheel 22 is fixed on the output shaft 21, and an eccentrically arranged shifting rod 23 is fixed on the end surface of the driving wheel 22. Fig.11 , Fig.12 As shown, the shift block 6 is a rectangular parallelepiped structure. Fig.12As shown, the lower part of the shift block 6 has a guide groove 63, and the shift block 6 is slidably connected to the guide rail 52 through the guide groove 63. The shift block 6 has a vertically arranged long groove 61 on the side facing the driving wheel 22, and the top of the long groove 61 has a flared opening 62. After starting the motor 3, the rotational motion output by the motor 3 is decelerated by the reducer 2, and drives the driving wheel 22 to rotate clockwise. When the driving wheel 22 rotates, the shift rod 23 rotates with the driving wheel 22. When the shift rod 23 rotates to the same height as the output shaft 21, the shift rod 23 enters the flared opening 62, and then after the shift rod 23 enters the long groove 61, the rotation of the shift rod 23 begins to push the shift block 6 to move leftward along the guide rail 52. At this time, the shift rod 23 moves downward relative to the shift block 6 along the long groove 61. The shift block 6 moves leftward, and the piston rod 42 pulls the piston 42 to move leftward. At this time, the energy storage spring 41 is compressed, the volume of the water storage chamber increases to generate negative pressure, and the external water enters the water storage chamber through the one-way valve 43. After the lever 23 rotates past the lowest point, the rotation of the lever 23 continues to push the shift block 6 to move to the left, and then the lever 23 moves upward along the long slot 61 relative to the shift block 6. When the lever 23 rotates again to the same height as the output shaft 21, the lever 23 returns to the flared opening 62 again. At this time, the energy storage spring 41 is compressed to the maximum, and the energy storage reaches the maximum value; the volume of the water storage chamber reaches the maximum value, and the water storage capacity is the maximum. With the further rotation of the driving wheel 22, the lever 23 then moves out of the flared opening 62. At this time, the lever 23 eliminates the shifting effect on the shift block 6, and the energy storage spring 41 releases the elastic potential energy, spraying the water in the water storage chamber through the water outlet 47 to clean the electrical equipment.

[0024] The present invention uses intermittent water spraying to isolate the passage of electric current, thereby realizing live cleaning, solving the problem of high cost of using pure water during live cleaning of traditional fire-fighting equipment. The present invention combines two usage scenarios of cleaning and fire extinguishing, uses intermittent water spraying at low cost, and is not limited to the use of media.
