DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Reference Figures 1 to 4A capacitor compensation cabinet with dustproof function includes a cabinet body 1, an air inlet is fixed at the bottom of the cabinet body 1, a dustproof plate 15 is fixed at the air inlet, the dustproof plate 15 has dustproof holes 14 distributed in a rectangular array, and a filter belt 25 is fitted on one side of the dustproof plate 15 close to the inside of the cabinet. The filter belt 25 is used to absorb dust in the air and reduce the impact of dust on the capacitor compensation cabinet.

[0026] Reference Figure 3 , and two pairs of pillars 2 are fixed at the inner bottom end of the cabinet 1, one pair of pillars 2 is rotatably connected to the opposite side with a material roller 22, and the other pair of pillars 2 is rotatably connected to the opposite side with an electric roller 21 and a roller 23, and the electric roller 21 is located above the roller 23, and each pair of pillars 2 is rotatably connected to the opposite side with a limit shaft 24 at a corresponding position, and a motor 26 for driving the electric roller 21 is fixedly installed on one of the pillars 2, and the material roller 22 releases a surplus belt and a filter belt 25. To ensure that the filter belt 25 can still drive the roller 23 to rotate when the surplus is insufficient, a surplus belt is set at the end of the filter belt 25, and the filter belt 25 bypasses two limit shafts 24 and a roller 23 and is reeled up by the electric roller 21. To allow air to flow through the filter belt 25, a limit shaft 24 is set to fit the filter belt 25 to the dustproof plate 15, and the filter belt 25 completely covers the dustproof hole 14.

[0027] An air volume sensor (the prior art) is provided at a position near the filter belt 25 of the cabinet. The air volume sensor is preset with a lower limit value of the air volume. When the air volume sensor detects that the air volume has reached the lower limit value, a signal is sent to the controller to start the motor 26 to drive the electric roller 21 to rotate. The electric roller 21 winds up the filter belt 25 to pull the filter belt 25, and transmits it under the guidance of the roller 23 and the limit shaft 24, so that the area where the filter belt 25 was originally blocked by dust is wound by the electric roller 21, and the new filter belt 25 on the material roller 22 is transmitted to the top of the dustproof hole 14. During the transmission process, the filter belt 25 always keeps in contact with the dustproof plate 15 due to the limiting effect of the limit shaft 24.

[0028] In order to ensure that the length of the filter belt 25 is consistent each time it is replaced and to alarm when there is no remaining filter belt 25, the following settings are made: referring to the pillar 2, the inner wall of the cabinet 1 is horizontally fixedly connected with a fixing plate 3, the lower end of the fixing plate 3 is rotatably connected with a screw 36, the lower end of the screw 36 is fixedly connected with a connecting rod 363, and the lower end of the connecting rod 363 is rotatably connected to the inner bottom end of the cabinet 1, the lower end of the fixing plate 3 is fixedly connected to the inner bottom end of the cabinet 1 with a measuring rod 35, the measuring rod 35 has a plurality of through holes 31 evenly distributed in the vertical direction, the spacing between adjacent through holes 31 is consistent with the length of the filter belt 25 to be replaced, and the measuring rod 35 is distributed in parallel with the screw 36, and a slide plate 3 is sleeved on the screw 36 and the measuring rod 35 4, and a through-beam photoelectric sensor is fixed on the slide plate 34. When the slide plate 34 slides upward, the transmitting end 32 and the receiving end 33 at both ends of the through-beam photoelectric sensor form a through-beam through the through hole 31, and send a signal to the controller, indicating that the filter belt 25 covering the dustproof hole 14 is completely replaced and the motor 26 is turned off, and the controller has a counting ability. In order to reduce the loss of the through-beam photoelectric sensor, when the wind volume sensor detects that the wind volume does not reach the set wind volume lower limit, the through-beam photoelectric sensor will be in a silent state. When the wind volume sensor detects that the wind volume reaches the set wind volume lower limit, this wind volume sensor will transmit a signal to start the motor and wake up the through-beam photoelectric sensor in the silent state.

[0029] An alarm 12 is fixed to the outside of the cabinet 1 near the top of the measuring rod 35. When the slide plate 34 slides to the top, the corresponding through-type photoelectric sensor moves up to the corresponding position of the uppermost through hole 31 of the measuring rod 35. The number of times the filter belt 25 is replaced counted by the controller reaches the set peak value, and the controller will activate the alarm 12 to remind that the surplus belt on the material roller 22 covers the dustproof hole 14 and the filter belt 25 needs to be replaced.

[0030] In order to enable the screw rod 36 to drive the measuring rod 35 to rise through the limiting effect during the rotation process, a hexagonal slot is provided at the lower end of the slide plate 34, and the hexagonal nut 361 is threadedly connected with the screw rod 36, and the hexagonal nut 361 located in the hexagonal slot and the slide plate 34 are raised by the rotation of the screw rod 36;

[0031] The hexagonal slot is not limited to a hexagonal shape, and other shape features with a limiting function can be adopted. The main purpose is that the slot can constrain the nut on the screw rod 36 so that the nut can drive the slide plate 34 to move upward.

[0032] After replacing the filter belt 25, the slide plate 34 needs to be restored to the starting position to provide space for lifting the slide plate 34 upwards. Therefore, this size limit is set: there is a distance between the through hole 31 at the top and the fixing plate 3 that is greater than the thickness of the slide plate 34, so that the lower end of the slide plate 34 fits into the hexagonal nut 361 in the hexagonal slot and rotates to the bottom of the screw rod 36. The slide plate 34 can be put down and restored to the starting position to reuse the replaced filter belt 25.

[0033] The inner and outer sides of the pillar 2 are connected and power is transmitted through a bevel gear pair 362. The bevel gear pair 362 includes an active bevel gear and a passive bevel gear that mesh with each other. The active bevel gear is fixed to one end of the roller 23, and the passive bevel gear is fixed to the lower end of the screw 36 without affecting the upward movement of the hexagonal nut 361. The roller 23 rotates to make the slide plate 34 slide upward to replace the filter belt 25 and issue an alarm.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
