Description

Technical Field

[0001] This application relates to the field of seismic devices, especially the seismic devices for fire protection mechanical and electrical systems. Background Art

[0002] Currently, the seismic standards clearly require that for buildings involving the production and storage of important equipment and facilities that need to quickly resume their functions after an earthquake, the seismic fortification category shall not be lower than the key fortification category. For example, the cabinet room for power dispatching, which undertakes the task of regional power supply guarantee, must be designed according to the seismic grade of Class B, and the seismic measures need to be increased by one degree based on the local fortification intensity.

[0003] The fire control cabinet is a functional cabinet that controls the operation of the fire pump. When the fire pump control cabinet receives a fire alarm signal, it immediately starts or stops the fire pump according to the command to achieve fire extinguishing. The fire control cabinet is used for the start control of the fire pump and the pressure stabilizing pump, has a dual-power supply inlet, has two working modes of manual and automatic, and has a linkage function with the fire control center, and plays a protective role for the fire pump and the pressure stabilizing pump against phase loss, overload, etc.

[0004] In the prior art, a seismic device for a fire protection mechanical and electrical cabinet includes a base, and there are multiple connecting springs between the base and the cabinet. The base is used to be fixed on the ground. During an earthquake, the base and the cabinet are connected through the connecting springs to reduce the shaking of the cabinet and improve the stability of the cabinet in use.

[0005] For the above-mentioned related patents, when an earthquake comes, the longitudinal wave is transmitted to the building first, causing the building to jolt up and down, and then the transverse wave, causing the building to shake left and right. Using connecting springs has a good effect on the up-and-down jolting of the longitudinal wave. Due to the large volume and high height of the fire protection mechanical and electrical cabinet, when the shaking at the top of the cabinet cannot keep up with the shaking at the bottom of the cabinet during the left-and-right shaking of the transverse wave, it is not only easy to damage the structure of the cabinet, but also easy to cause the separation between the cabinet and the base, resulting in the cabinet being separated from the ground and damaging the normal use of the cabinet, which needs to be improved. Summary of the Invention

[0006] In order to reduce the damage of the cabinet during an earthquake, improve the stability of the cabinet fixation, and ensure the normal use of the cabinet, this application provides a seismic device for a fire protection mechanical and electrical system.

[0007] The seismic device for a fire protection mechanical and electrical system provided by this application adopts the following technical solutions:

[0008] It includes a base, a side seat and a cabinet, a plurality of bottom slides are provided at the bottom of the cabinet, a bottom sealed cavity is opened in the bottom slide, a bottom slider is slidably connected in the bottom sealed cavity, a first compression spring is provided between the end of the bottom slider away from the bottom slide and the base, a plurality of side slides are provided on the rear side of the cabinet, a side sealed cavity is opened in the side slide, the opening direction of the side sealed cavity is opposite to the opening direction of the bottom sealed cavity, the side sealed cavity is communicated with the bottom sealed cavity, a side slider is slidably connected in the side sealed cavity, a second compression spring is provided on the side of the side slider away from the side slide, and the second compression spring is provided between the side seat and the side slider.

[0009] By adopting the above technical solution, when an earthquake strikes, the longitudinal wave drives the building to vibrate up and down. Under the action of the first compression spring and the second compression spring, the vibration of the cabinet can be reduced, thereby improving the stability of the cabinet. When a transverse wave strikes, it will first drive the bottom of the cabinet to shake. At this time, on the one hand, the vibration of the cabinet is reduced under the action of the first compression spring and the second compression spring, and then the bottom slider is driven to slide closer to or away from the side slide. Since the bottom sealing cavity is connected to the side sealing cavity, the gas in the sealing cavity pushes the side slide in the side sealing cavity out or in. At this time, the cabinet can be shaken synchronously up and down, reducing the situation where the upper and lower parts of the cabinet shake in different directions, reducing damage to the cabinet structure, and reducing the inertia force generated when the cabinet shakes, which causes the cabinet to fall off, thereby improving the stability of the cabinet fixation.

[0010] Preferably, a support plate is hingedly connected to the bottom slide, and the support plate abuts against the base for supporting the cabinet. A limiting ring is provided on the side wall of the support plate, and a limiting hole is opened on the bottom slide. A limiting rod is passed through the limiting hole, and the limiting rod is also passed through the limiting ring.

[0011] By adopting the above technical solution, under normal working conditions, the support piece can be limited by inserting the limit rod into the limit ring and the limit hole, so that the support piece can support the cabinet more stably and improve the stability of the cabinet fixation. When an earthquake strikes, the vibration of the cabinet will drive the limit rod to impact the bottom slide, causing the support piece to be displaced from its original position and lose its function of supporting the cabinet, making the cabinet more convenient to resist earthquakes. At the same time, the limit on the bottom slide can be cancelled, improving the convenience of using the earthquake resistance function. When the limit rod is away from the bottom slide, the limit rod can be bent and drive the support piece to be displaced from the supporting position, making the cabinet more convenient to resist earthquakes. Using such a design not only meets the stability of the fire motor when used horizontally and reduces the shaking of the fire motor, but also reduces the shaking of the fire motor when an earthquake occurs, improving the stability of the use of the fire motor.

[0012] Preferably, four slide rails are symmetrically arranged at the four corners of the base. The length direction of the slide rails extends outward from the center of the base. A sliding seat is slidably connected to the slide rails. The bottom of the first compression spring is fixed to the sliding seat. A locking device for locking the position of the sliding seat is arranged on the sliding seat.

[0013] By adopting the above technical solution, when the cabinet shakes, the sliding seat will be driven to slide on the slide rail at this time. Then, in cooperation with the locking device, the sliding seat is locked, so as to realize the movement locking of the sliding seat. By adopting such a design, a dislocation can be generated between the sliding seat and the bottom slider, so that the first compression spring can support the cabinet in an inclined state, so as to better cope with the shaking of the transverse wave, ensure the stability of the cabinet, and reduce the damage to the cabinet.

[0014] Preferably, the locking device includes a positioning hole opened on one side of the sliding seat close to the slide rail. A positioning ball is arranged in the positioning hole. A positioning compression spring for pushing the positioning ball out is arranged in the positioning hole. A positioning arc groove for abutting against the positioning ball is opened at the position of the slide rail corresponding to the bottom slider. A positioning slot for inserting and matching with the positioning ball is opened on the surface of one end of the slide rail away from the positioning groove.

[0015] By adopting the above technical solution, when the positioning ball is inserted into the positioning arc groove, the first compression spring can support the cabinet vertically, improve the stability of the cabinet fixation, and reduce the movement of the cabinet. When the positioning ball is inserted into the positioning slot, the position of the sliding seat can be restricted under the action of the positioning ball, so that the first compression spring can more stably limit the vibration of the cabinet and improve the seismic effect of the fire protection electromechanical equipment.

[0016] Preferably, the slide rail is inclined downward along the direction from the center of the cabinet to the outside.

[0017] By adopting the above technical solution, the inclined slide rail can enable the sliding seat to better support the first compression spring, so that the pressure can be more evenly applied to the sliding seat during the deformation process of the first compression spring, and the stability of using the first compression spring is improved.

[0018] Preferably, an installation cavity is arranged in the cabinet. A plurality of installation plates are arranged in the installation cavity. Installation slots are arranged on the opposite side walls of the installation cavity. The installation plates are inserted into the installation slots. A deformation cavity is formed between the installation plates and the installation slots. A buffer pad is arranged in the deformation cavity. A hanging seat is arranged at the top of the installation cavity. A plurality of connecting ropes are arranged on the hanging seat. The connecting ropes connect the plurality of installation plates in sequence from top to bottom.

[0019] By adopting the above technical solution, during use, electrical appliances such as switches are installed on the mounting plate. When installing, heavier electrical appliances are installed at the bottom, which can make the bottom heavier, lower the center of gravity of the entire anti-seismic device, and then cooperate with the connecting rope to apply the weight to the hook, so that the internal weight acts on the top of the cabinet. At this time, the weight is equivalent to applying a vertical pressure to the cabinet structure, making the connection between the components of the cabinet tighter. When horizontal or vertical vibrations occur during an earthquake, this pressure helps to resist the relative displacement and deformation between the components, making the cabinet as a whole more stable, reducing the deformation of the cabinet caused by loose connections, and improving the stability of using the cabinet.

[0020] Preferably, a plurality of connecting tension springs are arranged between the mounting plate and the side wall of the mounting cavity.

[0021] By adopting the above technical solution, the connecting tension springs can be used to limit the mounting plate, reduce the shaking of the mounting plate, and improve the stability of using the mounting plate.

[0022] Preferably, a positioning rod is arranged on one side of the cabinet close to the first compression spring, a positioning block is arranged on the base, the positioning block and the positioning rod are coaxially arranged, and a positioning ring is sleeved on the positioning block and the positioning rod. The positioning ring is composed of two mutually hinged positioning arc pieces. One of the positioning arc pieces is provided with a plug-in clamping block, and the other positioning arc piece is provided with a plug-in slot that is clamped and matched with the plug-in clamping block.

[0023] By adopting the above technical solution, positioning the positioning block and the positioning rod through the positioning ring can make the cabinet more stably fixed when there is no earthquake, and improve the stability of fixing the cabinet. After an earthquake, the positioning rod and the positioning block shake, which will push open the two positioning arc pieces, so that the cabinet can move freely, improve the anti-seismic ability of the cabinet, and improve the convenience of using the anti-seismic device.

[0024] Preferably, a plurality of positioning inserts are arranged on the inner wall of the positioning arc piece, and positioning locking grooves that are inserted and matched with the positioning inserts are opened on the side walls of the positioning rod and the positioning block.

[0025] By adopting the above technical solution, when the two positioning arc pieces are inserted and locked, at this time, inserting the positioning inserts into the positioning locking grooves can achieve locking in the vertical direction. When the longitudinal pressure is large, the positioning inserts can be directly damaged, or when the positioning arc pieces are opened, the positioning inserts are drawn out of the positioning locking grooves, so that the cabinet can be more stable when there is no earthquake and improve the convenience of the cabinet's anti-seismic performance.

[0026] Preferably, a plurality of threading holes are provided on the rear side of the cabinet, and a plurality of ball heads are provided on the cabinet near the threading holes. A ball head seat is connected to the ball head, and a first threading ring and a second threading ring are provided at both ends of the ball head seat respectively. The end of the ball head seat away from the ball head is rotatably connected to a hinged rod, and the end of the hinged rod away from the ball head seat is provided with a third threading ring.

[0027] By adopting the above technical solution, when connecting the wires, the wires are passed through the third wire ring, the second wire ring and the first wire ring in sequence, and finally enter the cabinet through the wire hole, so that the wires can be connected more conveniently. When an earthquake occurs, the hinged rod and the ball head seat provide the wires with more deformation space, reducing the damage to the wires during an earthquake and improving the stability of the cabinet.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. When an earthquake strikes, the longitudinal wave drives the building to vibrate up and down. Under the action of the first and second compression springs, the vibration of the cabinet can be reduced, thereby improving the stability of the cabinet. When a transverse wave strikes, it will first drive the bottom of the cabinet to shake. At this time, on the one hand, the vibration of the cabinet is reduced under the action of the first and second compression springs, and then the bottom slider is driven to slide closer to or away from the side slide. Since the bottom sealing cavity is connected to the side sealing cavity, the gas in the sealing cavity pushes the side slide in the side sealing cavity out or in. At this time, the cabinet can be shaken up and down synchronously, reducing the situation where the upper and lower parts of the cabinet shake in different directions, reducing damage to the cabinet structure, and reducing the inertia force generated when the cabinet shakes, which may cause the cabinet to fall off, thereby improving the stability of the cabinet fixation.

[0030] 2. Under normal working conditions, the support piece can be limited by inserting the limit rod into the limit ring and the limit hole, so that the support piece can support the cabinet more stably and improve the stability of the cabinet fixation. When an earthquake strikes, the vibration of the cabinet will drive the limit rod to impact the support block, causing the support piece to be out of position and lose its function of supporting the cabinet, making the cabinet more convenient to resist earthquakes. At the same time, the limit on the bottom slider can be cancelled, improving the convenience of using the earthquake resistance function. When the support block is away from the bottom slide, the limit rod can be bent and drive the support piece out of the support position, making the cabinet more convenient to resist earthquakes. This design not only meets the stability of the fire motor when used horizontally and reduces the shaking of the fire motor, but also reduces the shaking of the fire motor when an earthquake occurs, improving the stability of the use of the fire motor.

[0031] 3. During use, install electrical appliances such as switches on the mounting plate. When installing, install heavier electrical appliances at the bottom, which can make the bottom heavier, lower the center of gravity of the entire seismic device, and then cooperate with the connecting rope to apply the weight to the hook, so that the internal weight acts on the top of the cabinet. At this time, the weight is equivalent to applying a vertical pressure to the cabinet structure, making the connection between the components of the cabinet closer. When horizontal or vertical vibrations occur during an earthquake, this pressure helps to resist the relative displacement and deformation between components, making the entire cabinet more stable, reducing the deformation of the cabinet caused by loose connections, and improving the stability of the cabinet during use.

Detailed Description of the Invention

[0039] The following is combined with the attached Figure 1 -Figure 6 Further detailed description of this application is provided as follows.

[0040] An embodiment of this application discloses a seismic device for a fire protection mechanical and electrical system.

[0041] Embodiment 1

[0042] Referring to Figure 1 , the seismic device for the fire protection mechanical and electrical system includes a base 4, a side seat 2 and a cabinet 1. The base 4 and the side seat 2 form an L-shaped steel plate, and the L-shaped steel plate is fixed to the ground. The cabinet 1 is a rectangular cabinet. A plurality of bottom sliding seats 14 are provided at the bottom of the cabinet 1. A bottom sealing cavity 15 is formed in the bottom sliding seat 14. A bottom slider 21 is slidably connected in the bottom sealing cavity 15. The bottom slider 21 can push the air in the bottom sealing cavity 15. One side of the bottom slider 21 close to the cabinet 1 abuts against the cabinet 1. A first compression spring 3 is installed between one end of the bottom slider 21 away from the bottom sliding seat 14 and the base 4. The first compression spring 3 is used to reduce the transmission of lateral and longitudinal vibrations to the frame. A plurality of side sliding seats 5 are fixed to the rear side of the cabinet 1. The side sliding seats 5 are arranged close to the top of the cabinet 1. A side sealing cavity is formed in the side sliding seat 5. The opening direction of the side wall sealing cavity is opposite to that of the bottom sealing cavity 15. The side sealing cavity is communicated with the bottom sealing cavity 15. A side slider 6 is slidably connected in the side sealing cavity. One side of the side slider 6 close to the cabinet 1 abuts against the cabinet 1. A second compression spring 7 is fixed between the side seat 2 and the side slider 6 on the side away from the side sliding seat 5 of the side slider 6, so as to reduce the transmission of vibrations of the side seat 2 to the cabinet 1 and improve the fixing stability of the cabinet 1. By means of the first compression spring 3 and the second compression spring 7, the vibrations transmitted to the cabinet 1 can be greatly reduced. When the bottom of the cabinet 1 starts to vibrate, it will pull or push the bottom slider 21 to move, so as to push the gas in the bottom sealing cavity 15 into the side sealing cavity. Under the action of air pressure, the side sealing cavity will pull or push the side slider 6 to move. Since the bottom sealing cavity 15 and the side sealing cavity are arranged oppositely, the top and bottom of the cabinet 1 can be driven to move synchronously, so as to reduce the left-right swing of the cabinet 1 and the inertial force generated when the cabinet 1 swings, and improve the stability of using the cabinet 1.

[0043] A support piece 16 is hinged to the bottom sliding seat 14. The support piece 16 abuts against the base 4 to support the cabinet 1. When the support piece 16 rotates, the support piece 16 loses the function of supporting the cabinet 1. A limit ring 13 is fixed to the side wall of the support piece 16. A limit hole 11 is formed in the bottom slider 21. A limit rod 12 is inserted into the limit hole 11. The limit rod 12 also passes through the limit ring 13, which can limit the movement of the bottom slider 21. In the normal state, it can lock the cabinet 1, reduce the shaking of the cabinet 1, and improve the fixing stability of the cabinet 1.

[0044] The four corners of the base 4 are axisymmetrically designed with four slide rails 10. The length directions of the four slide rails 10 extend outward from the center of the base 4. The slide rails 10 are inclined upward in the direction outward along the middle line. A sliding seat 17 is slidably connected to the slide rails 10. The bottom of the first compression spring 3 is fixed to the sliding seat 17. A locking device for locking the sliding seat 17 is provided on the sliding seat 17. The locking device includes a positioning hole opened on one side of the sliding seat 17 close to the slide rail 10. A positioning ball 19 is installed in the positioning hole. A positioning compression spring 20 for pushing the positioning ball 19 to eject is fixed in the positioning hole. A positioning arc groove 18 for abutting against the positioning ball 19 is opened at the position of the slide rail 10 corresponding to the bottom slider 21. A positioning slot 40 for plugging and cooperating with the positioning ball 19 is opened on the surface of one end of the slide rail 10 far from the positioning arc groove 18. The depth of the positioning slot 40 is greater than the radius of the positioning ball 19. Thus, when the positioning ball 19 is plugged into the positioning slot 40, the locking of the sliding seat 17 can be realized, and the convenience of locking the sliding seat 17 is improved.

[0045] An installation cavity 24 is opened in the cabinet 1. A switch door is hingedly connected at the opening of the installation cavity 24. The opening and closing of the cabinet 1 are realized through the switch door. A plurality of mounting plates 9 are fixed in the installation cavity 24. The mounting plates 9 are rectangular plates and are vertically installed, so that electrical appliances such as switches can be fixed more conveniently. Mounting slots 26 are opened on the opposite side walls of the installation cavity 24. The mounting plates 9 are plugged into the mounting slots 26. A deformation cavity is formed between the mounting plates 9 and the mounting slots 26. A buffer pad 25 is adhesively fixed in the deformation cavity. The buffer pad 25 is made of rubber material. The buffer pad 25 has greater elasticity, reduces the support of the installation on the side walls of the mounting slots 26, and can play a buffering role. A hanging seat 22 is fixed at the top of the installation cavity 24. A plurality of connecting ropes 23 are connected to the hanging seat 22. The connecting ropes 23 are made of thinner steel wires to better ensure the strength of the connecting ropes 23. The connecting ropes 23 are sequentially connected to a plurality of mounting plates 9 from top to bottom, so that the weight of the mounting plates 9 acts on the connecting ropes 23. A plurality of connecting tension springs 8 are fixed between the mounting plates 9 and the side walls of the installation cavity 24. The position of the mounting plates 9 can be restricted, and the stability of the fixing of the mounting plates 9 is improved.

[0046] The implementation principle of the seismic device for the fire protection electromechanical system in the embodiment of the present application is as follows: During normal operation, the cooperation between the limit rod 12 and the support piece 16 realizes the locking of the bottom slider 21 and the first compression spring 3, reducing the movement of the cabinet 1 and improving the stability of the cabinet 1 during use. When an earthquake strikes, first, the first compression spring 3 and the second compression spring 7 block the shear waves and longitudinal waves, reducing the shaking of the cabinet 1. Then, when the bottom slider 21 slides in the bottom sealing cavity 15, it can drive the side slider 6 to slide in the side sealing cavity, so that the upper and lower parts of the cabinet 1 can shake synchronously, reducing the situation of different-position shaking up and down of the cabinet 1, reducing the overall damage to the cabinet 1, and especially reducing the situation of the cabinet 1 detaching from the base 4, improving the fixing stability of the cabinet 1. And with the cooperation of multiple mounting plates 9 for fixing, heavier electrical appliances can be installed at the bottom, making the bottom heavier and lowering the center of gravity of the entire seismic device. Then, with the cooperation of the connecting rope 23, the weight acts on the hook, so that the internal weight acts on the top of the cabinet 1. At this time, the weight is equivalent to applying a vertical pressure to the structure of the cabinet 1, making the connection between the components of the cabinet 1 tighter. When horizontal or vertical vibrations occur during an earthquake, this pressure helps to resist the relative displacement and deformation between the components, making the cabinet 1 more stable as a whole, reducing the deformation of the cabinet 1 caused by loose connections, and improving the stability of the cabinet 1 during use.

[0047] Embodiment 2

[0048] Referring to Figure 5 and Figure 6 In this embodiment, the difference from Embodiment 1 is that a positioning rod 30 is fixed on one side of the cabinet 1 close to the first compression spring 3, and a positioning block 33 is fixed on the base 4. The positioning block 33 and the positioning rod 30 are coaxially arranged. A positioning ring is sleeved on the positioning block 33 and the positioning rod 30. The positioning ring is composed of two mutually hinged positioning arc pieces 27. A plug-in card block 29 is fixed on one of the positioning arc pieces 27, and a plug-in card slot 28 that is in snap-fit with the plug-in card block 29 is opened on the other positioning arc piece 27. Thus, during an earthquake, the two positioning arc pieces 27 can be opened by the shaking of the positioning rod 30 and the positioning block 33. A plurality of positioning inserts 31 are arranged on the inner wall of the positioning arc piece 27, and positioning lock grooves 32 that are in plug-in fit with the positioning inserts 31 are opened on the side walls of the positioning rod 30 and the positioning block 33. Through the cooperation of the positioning inserts 31 and the positioning lock grooves 32, the first compression spring 3 can be locked during normal use, improving the fixing stability of the cabinet 1.

[0049] A plurality of wire passing holes 37 are formed in the rear side of the cabinet 1. A plurality of ball heads 36 are fixed at positions of the cabinet 1 close to the wire passing holes 37. A ball head seat 35 is connected to the ball heads 36. A first wire passing ring 38 and a second wire passing ring 39 are respectively connected to two ends of the ball head seat 35. One end of the ball head seat 35 away from the ball head 36 is rotatably connected to a hinge rod 41. A third wire passing ring 34 is fixed at one end of the hinge rod 41 away from the ball head seat 35.

[0050] The implementation principle of Embodiment 2 is as follows: During operation, the electric wire passes through the third wire passing ring 34, the second wire passing ring 39 and the first wire passing ring 38 in sequence, and finally enters the installation cavity 24 through the wire passing hole 37. With such a design, when the cabinet 1 shakes, the risk of the electric wire breaking can be reduced, and the stability of connecting the cabinet 1 can be improved. Cooperating with the positioning arc piece 27 and the positioning insertion piece 31, the cabinet 1 can be limited. When no earthquake occurs, the cabinet 1 can be fixed more stably, and the fixing effect of the cabinet 1 can be improved.

[0051] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
