DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] Example: Reference Figure 1-Figure 11 A ventilation and heat dissipation device for an energy storage battery cabinet comprises a shell 101, on which eight covering slides 102 are slidably mounted in a rectangular array, the shell 101 is arranged on the back plate of the energy storage battery cabinet, and the energy storage battery cabinet stores eight batteries in a rectangular array, and the eight covering slides 102 correspond one-to-one to the corresponding battery positions in the battery cabinet, respectively, and square ventilation holes are arranged on the shell 101, and the eight covering slides 102 are arranged in pairs and opposite to each other, and two adjacent covering slides 102 located on the same side of the shell 101 are slidably matched, and when two oppositely arranged cooling fans 104 are in a contact state, the square ventilation holes on the shell 101 are in a covering state, and the cooling fans 104 correspond one-to-one to the positions of the corresponding covering slides 102.

[0028] A limit assembly is provided between the cover slide 102 and the housing 101, the limit assembly includes a fan-shaped strip 118 rotatably mounted on the housing 101, an L-shaped slide 114 is fixedly provided on the cover slide 102, a spring is provided between the L-shaped slide 114 and the housing 101, the L-shaped slide 114 is provided on the inner side of the housing 101, the cover slide 102 is provided on the outer side of the housing 101, an arc-shaped slide groove cooperating with the fan-shaped strip 118 is provided on the L-shaped slide 114, and the limit assembly also includes a limit rack 120 slidably mounted on the housing 101 3. A torsion spring is arranged between the fan-shaped strip 118 and the housing 101, one end of the torsion spring is fixedly connected to the fan-shaped strip 118, and the other end of the torsion spring is fixedly connected to the housing 101. A limit gear 121 is fixedly installed on the fan-shaped strip 118, and the limit gear 121 and the limit rack 123 are meshed to form a gear rack pair. A quick push plate 113 is symmetrically slidably installed on the housing 101, and an expansion push block 124 is fixedly arranged on the limit rack 123. The two quick push plates 113 are respectively used to push the corresponding four expansion push blocks 124 to move synchronously.

[0029] In the initial position, the square ventilation holes of the shell 101 are covered by eight covering slides 102. At this time, the springs between the covering slides 102 and the shell 101 are in a stretched state, and the torsion springs between the fan-shaped strips 118 and the shell 101 are not compressed, that is, the fan-shaped strips 118 and the corresponding arc-shaped grooves on the L-shaped slides 114 are in engagement. Under the action of the fan-shaped strips 118, the corresponding L-shaped slides 114 cannot move freely, thereby achieving the locking of the position of the corresponding covering slides 102.

[0030] Pushing the unfolding push block 124 alone will move the corresponding limit rack 123, thereby causing the limit gear 121 to rotate, and the fan-shaped strip 118 to rotate synchronously. The torsion spring between the fan-shaped strip 118 and the shell 101 is compressed, and finally the fan-shaped strip 118 is disengaged from the corresponding L-shaped slide 114, that is, the position of the L-shaped slide 114 is locked. Under the action of the spring between the L-shaped slide 114 and the shell 101, the covering slide 102 and the L-shaped slide 114 move synchronously in a direction away from the relatively arranged covering slide 102.

[0031] A self-locking unit 1 is arranged between the fan-shaped strip 118 and the shell 101. The self-locking unit 1 includes a self-locking ratchet ring 119 slidably mounted on the shell 101. A spring is arranged between the self-locking ratchet ring 119 and the shell 101. A self-locking ratchet 120 is also fixedly mounted on the limiting gear 121. When the self-locking ratchet 120 and the self-locking ratchet ring 119 are engaged, a ratchet mechanism is formed.

[0032] The housing 101 is provided with a slide plate 109 which is slidably mounted, a transverse adjustment screw rod 107 which is rotatably mounted on the housing 101, the transverse adjustment screw rod 107 and the slide plate 109 forming a spiral pair, a transverse adjustment motor 108 which is fixedly mounted on the housing 101, the output shaft of the transverse adjustment motor 108 and the transverse adjustment screw rod 107 being fixedly connected, a driving push plate 115 which is slidably mounted on the slide plate 109, a vertical adjustment screw rod 110 which is rotatably mounted on the slide plate 109, the vertical adjustment screw rod 110 and the driving push plate 115 are connected to the slide plate 109, and the vertical adjustment screw rod 110 and the driving push plate 115 are connected to the slide plate 109. The push plate 115 forms a spiral pair, a vertical positioning motor 111 is fixedly installed on the positioning slide 109, the output shaft of the vertical positioning motor 111 is fixedly connected to the vertical positioning screw 110, an auxiliary push block 117 is fixedly set on the quick push plate 113, trapezoidal push blocks 116 are symmetrically fixed on the side of the driving push plate 115, and an unlocking push rod 122 is fixedly set on the self-locking ratchet ring 119. The trapezoidal push block 116 closest to the covering slide 102 is used to push the unlocking push rod 122 to move.

[0033] In the initial position, the spring between the self-locking ratchet ring 119 and the housing 101 is not compressed, and the self-locking ratchet ring 119 and the self-locking ratchet wheel 120 are in an engaged state.

[0034] The lateral positioning motor 108 is started to drive the lateral positioning screw 107 to rotate, so that the positioning slide 109 moves along the axis of the lateral positioning screw 107. The vertical positioning motor 111 is started to drive the vertical positioning screw 110 to rotate, so that the driving push plate 115 moves along the axis of the vertical positioning screw 110. When it is necessary to open the covering slide 102 corresponding to a certain battery, the lateral positioning motor 108 and the vertical positioning motor 111 are started to move the driving push plate 115 to the position where the expansion push block 124 corresponding to the covering slide 102 is located, and then the vertical positioning motor 111 is started to drive the driving push plate 115 to move in the direction close to the expansion push block 124, so that the driving push plate 115 contacts The expansion push block 124 drives the push plate 115 to continue moving, so that the limit rack 123 and the expansion push block 124 move synchronously, and then the fan-shaped strip 118 and the limit gear 121 rotate synchronously, and the torsion spring between the fan-shaped strip 118 and the shell 101 is compressed. Since the self-locking ratchet ring 119 and the self-locking ratchet 120 constitute a ratchet mechanism, the self-locking ratchet 120 rotates relative to the self-locking ratchet ring 119 at this time, but the self-locking ratchet 120 cannot rotate in the opposite direction relative to the self-locking ratchet ring 119 at this time, that is, the rotation direction of the fan-shaped strip 118 is restricted. After the fan-shaped strip 118 releases the lock on the L-shaped slide plate 114, the covering slide plate 102 moves to the outside of the square ventilation hole on the shell 101.

[0035] When it is necessary to return the covering slide 102 to the initial position, the lateral positioning motor 108 and the vertical positioning motor 111 are started to drive the push plate 115 to move to the outer side of the end of the L-shaped slide 114 corresponding to the covering slide 102, and then the vertical positioning motor 111 is started to drive the push plate 115 to move and contact the L-shaped slide 114, and then the push plate 115 is driven to continue to move, and the covering slide 102 and the L-shaped slide 114 move synchronously, and the spring between the L-shaped slide 114 and the housing 101 is stretched. During the movement of the driving push plate 115, the trapezoidal push block 116 closest to the covering slide 102 contacts the covering slide 102. 2, under the action of the inclined surface of the trapezoidal push block 116, the unlocking push rod 122 moves towards the direction close to the housing 101, the spring between the self-locking ratchet ring 119 and the housing 101 is compressed, and finally the self-locking ratchet ring 119 and the self-locking ratchet wheel 120 are disengaged, and the torsion spring between the fan-shaped strip 118 and the housing 101 is restored. Finally, under the action of the driving push plate 115, the covering slide 102 returns to the initial position. At this time, the trapezoidal push block 116 and the unlocking push rod 122 are still in the engaged state, that is, the fan-shaped strip 118 corresponding to the covering slide 102 is engaged with the arc-shaped slide groove on the corresponding L-shaped slide 114.

[0036] When it is necessary to quickly open the covering slide 102, the driving adjustment slide 109 and the vertical adjustment motor 111 make the driving push plate 115 contact one of the two auxiliary push blocks 117, and then under the action of the driving push plate 115, the quick push plate 113 is moved in the direction away from the other quick push plate 113, so that the four unfolding push blocks 124 corresponding to the quick push plate 113 are moved synchronously, and then the four fan-shaped strips 118 corresponding to the quick push plate 113 are rotated synchronously, so that the four fan-shaped strips 118 corresponding to the quick push plate 113 are all unlocked from the corresponding covering slide 102 position, that is, the covering slide 102 corresponding to the quick push plate 113 is quickly opened, and the above steps are repeated to move the other quick push plate 113, that is, the eight covering slides 102 are quickly opened.

[0037] Eight cooling fans 104 are rotatably mounted on the shell 101 in a rectangular array, eight transmission pulleys 106 are rotatably mounted on the shell 101, a transmission belt 105 is arranged between the eight transmission pulleys 106, an auxiliary short rod 112 is arranged between two adjacent transmission pulleys 106, the auxiliary short rods 112 are fixedly mounted on the shell 101, the shell 101 is used to make the transmission pulleys 106 in contact with the transmission belt 105, a protective cover 125 is symmetrically fixedly mounted on the inner side of the shell 101, the protective cover 125 is used to protect internal components, a cooling motor 103 is fixedly mounted on the protective cover 125, the output shaft of the cooling motor 103 is fixedly connected to the corresponding self-locking ratchet 1206, the cooling motor 103 is started to drive the corresponding transmission pulley 106 to rotate, and under the action of the transmission belts 105 and 11, the eight transmission pulleys 106 rotate synchronously.

[0038] A transmission assembly is provided between the cooling fan 104 and the corresponding transmission pulley 106, and the transmission assembly is used to make the transmission pulley 106 drive the corresponding cooling fan 104 to rotate. The transmission assembly includes an L-shaped slide 132 slidably mounted on the housing 101, and a transmission friction wheel 129 is rotatably mounted on the L-shaped slide 132. The cooling fan 104 and the transmission friction wheel 129 are both fixedly mounted with pulleys. An elastic belt 133 is provided between the pulley on the cooling fan 104 and the pulley on the transmission friction wheel 129 in the same transmission assembly. The elastic belt 133 is elastic, and a limit block is fixedly arranged on the L-shaped slide 132. The limit block on the L-shaped slide 132 is used to limit the position of the L-shaped slide 132 relative to the shell 101, that is, under the action of the limit block and the elastic belt 133, the elastic belt 133 is in an unstretched state, and the elastic belt 133 will not be out of contact with the corresponding pulley. A driving friction wheel 128 is fixedly installed on the transmission pulley 106, and there is friction between the driving friction wheel 128 and the corresponding transmission friction wheel 129 when the two are in contact.

[0039] Repeat the above steps, start the positioning slide 109 and the vertical positioning motor 111, so that the driving push plate 115 contacts the L-shaped slide 132 corresponding to the covering slide 102 to be opened. At this time, the driving push plate 115 is in contact with the unfolding push block 124 corresponding to the covering slide 102, and then the driving push plate 115 is driven to move. At this time, the L-shaped slide 132 and the unfolding push block 124 move synchronously. The movement of the L-shaped slide 132 causes the transmission friction wheel 129 to rotate synchronously, and the elastic belt 133 is stretched. Finally, when the fan-shaped strip 118 releases the lock on the position of the L-shaped slide 114, the transmission friction wheel 129 contacts the corresponding driving friction wheel 128. Under the action of the friction force between the driving friction wheel 128 and the transmission friction wheel 129, the transmission friction wheel 129 rotates synchronously, and then under the action of the elastic belt 133, the cooling fan 104 is rotated.

[0040] A self-locking unit 2 is provided between the transmission assembly and the shell 101, and the self-locking unit 2 includes a self-locking slide 130 slidably mounted on the shell 101, a spring is provided between the self-locking slide 130 and the shell 101, and a plurality of ratchets are evenly and fixedly provided on the self-locking slide 130 and the L-shaped slide 132. When the ratchets on the self-locking slide 130 are engaged with the ratchets on the corresponding L-shaped slide 132, a ratchet mechanism is formed. A quick push plate 2 126 is also symmetrically and slidably mounted on the shell 101. The two quick push plates 126 are respectively used to push the corresponding four L-shaped slides 132 to move, and an auxiliary push block 2 127 is fixedly provided on the quick push plates 126. An unlocking push rod 2 131 is fixedly provided on the self-locking slide 130, and the trapezoidal push block 116 farthest from the covering slide 102 is used to push the unlocking push rod 2 131 to move.

[0041] In the initial position, the spring between the self-locking slide 130 and the housing 101 is not compressed. At this time, the self-locking slide 130 and the corresponding L-shaped slide 132 form a ratchet mechanism, pushing the L-shaped slide 132 to move in the direction close to the corresponding driving friction wheel 128. The L-shaped slide 132 slides relative to the self-locking slide 130. At this time, the L-shaped slide 132 cannot move relative to the self-locking slide 130 in the direction away from the driving friction wheel 128. When the trapezoidal push block 116 closest to the housing 101 pushes the unlocking push rod 122 to move. When the self-locking ratchet ring 119 releases the lock on the position of the self-locking ratchet wheel 120, the self-locking slide plate 130 releases the lock on the position of the L-shaped slide seat 132, and under the action of the elastic force of the elastic belt 133, the L-shaped slide seat 132 returns to the initial position, and finally the limit block on the L-shaped slide seat 132 contacts the shell 101 and cannot move further, that is, the L-shaped slide seat 132 returns to the initial position.

[0042] Working principle: Multiple temperature sensors are arranged inside the housing 101, and the temperature of each battery is monitored by the temperature sensors. When the temperature of a battery becomes high, the horizontal adjustment motor 108 and the vertical adjustment motor 111 are started to make the fan-shaped strip 118 corresponding to the covering slide 102 unlock the covering slide 102. Under the action of the spring between the covering slide 102 and the housing 101, the covering slide 102 is quickly opened, and at the same time when the fan-shaped strip 118 unlocks the covering slide 102, the transmission friction wheel 129 corresponding to the covering slide 102 contacts the corresponding driving friction wheel 128, so that the covering slide 102 is opened. 02, the cooling fan 104 corresponding to the cover slide 102 rotates, that is, the rapid cooling of the battery is achieved. When the cover slide 102 needs to be closed, the horizontal positioning motor 108 and the vertical positioning motor 111 are started to make the L-shaped slide 114 corresponding to the cover slide 102 move toward the direction close to the relatively set cover slide 102, and in the process of driving the push plate 115 to move, the self-locking unit 1 and the self-locking unit 2 corresponding to the cover slide 102 release the lock on the position of the fan-shaped strip 118 and the L-shaped slide seat 132, that is, the fan-shaped strip 118 re-locks the position of the cover slide 102, and the cooling fan 104 stops rotating.

[0043] When rapid heat dissipation of the interior is required, the lateral positioning motor 108 and the vertical positioning motor 111 are started so that the driving push plate 115 first pushes one of the two rapid push plates 113 to slide, and the rapid push plate 2 126 corresponding to the rapid push plate 113 slides synchronously, so that the four covering slides 102 corresponding to the rapid push plate 113 are quickly opened and the four cooling fans 104 are rotated, and then the above steps are repeated so that the other rapid push plate 113 and the rapid push plate 2 126 slide synchronously, so that the eight covering slides 102 are opened and the eight cooling fans 104 are rotated, thereby achieving rapid heat dissipation of the interior.

[0044] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
