[0031] The material blocking support device includes a linear motor 3 fixedly arranged on the support plate 10, a pedal 30 horizontally extends from the output end of the linear motor 3, and a gap 32 is arranged on the pedal 30 at a position corresponding to the screw rod 221; a scraper 31 is arranged on the support plate 10 at a position corresponding to the pedal 30, and the lower end surface of the scraper 31 abuts against the upper end surface of the pedal 30.
[0032] A hanging ring 301 is arranged on the extending end of the pedal 30, a pull rope 111 is arranged on the groove wall of the lifting net groove 11, and a hook 112 is arranged on the pull rope 111, and the hook 112 is connected with the hanging ring 301 when the pedal 30 is moved to the extending position.
[0033] A horizontal protrusion 4 extends from one side of the lifting net groove 11, a first filter screen 110 is arranged on the protrusion 4 and communicates with the water inlet channel, the upper end surface of the extending end of the protrusion 4 is provided with a first inclined surface section 41 with an outer high and an inner low, and a second inclined surface section 33 with an outer low and an inner high is arranged on the upper end surface of the extending section of the pedal 30; when the pedal 30 is extended by the linear motor 3, the extending end surface of the pedal 30 abuts against and is limited by the outer side wall of the protrusion 4, and the first inclined surface section 41 and the second inclined surface section 33 communicate to form an inclined surface structure for guiding sewage to the first filter screen 110.
[0034] Two horizontal supporting rods 5 are symmetrically arranged on the outer side wall of the protrusion 4, and a second guide plate 51 is vertically arranged on the extending end of each supporting rod 5, and the inner side wall of the second guide plate 51 abuts against the outer side wall of the corresponding end of the slag blocking frame 2.
[0035] The water inlet of the water tank 1 is communicated with the water inlet channel, and a second filter screen 12 is arranged at the water inlet.
[0036] The use principle of the utility model is as follows:
[0037] As Figure 1 shown, during normal use, the slag blocking frame 2 is located in the water inlet channel, and the slag blocking screen 23 blocks impurities in water, at this time, the inner side wall of the second guide plate 51 is attached to the outer side wall of the corresponding end of the slag blocking frame 2, and the screw rod 221 screwed with the slag blocking frame 2 also plays a role of directional connection, so that the slag blocking frame 2 does not produce deflection in the direction of water flow, that is, the slag blocking frame 2 remains vertical in the water inlet channel, and no gap is generated at the bottom of the water inlet channel, which can effectively prevent impurities from leaking, and the second filter screen 12 only plays a role of secondary filtration at this time.
[0038] As Figures 2 to 7 shown, when the slag blocking screen 23 needs to be cleaned, the water pumping motor (not marked) is closed, and after the water flow of the water inlet is smooth (that is, the amount of subsequent water inlet has passed the slag blocking screen 23), the power motor 22 is started, and the slag blocking frame 2 screwed by the screw rod 221 is moved upward, in this process, first, the inner side wall of the second guide plate 51 is attached to the outer side wall of the corresponding end of the slag blocking frame 2, which can prevent the slag blocking frame 2 from rotating and moving upward, after rising a distance, the outer side wall of the first guide plate 24 is attached to the outer side wall of the corresponding end of the slag blocking frame 2, and at this time, the second guide plate 51 still remains attached to the slag blocking frame 2, and the first guide plate 24 is still attached to the slag blocking frame 2 when the slag blocking frame 2 is moved to the position; therefore, the slag blocking frame 2 is limited by the attachment of the first guide plate 24 and the second guide plate 51 in the axial direction of the screw rod 221, and the stable upward movement of the slag blocking frame 2 is effectively realized.
[0039] Then, the power motor 22 is closed, and the linear motor 3 is started, the pedal 30 is horizontally extended, the corresponding position of the exposed screw rod 221 is moved into the accommodation groove 32, the end face of the extended end of the pedal 30 is abutted and limited to the outer side wall of the boss 4, at the same time, the first inclined section 41 and the second inclined section 33 are communicated to form an inclined surface structure for guiding the cleaning sewage to the first filter screen 110, that is, the pedal 30 constitutes a new platform position for the movement of the staff in the lifting screen groove 11, which can prevent the cleaned sundries from directly falling back to the water inlet channel, and the cleaning sewage flows to the first filter screen 110 through the inclined surface structure and flows into the water inlet channel, which also achieves the purpose of saving water resources; then, the hook 112 is hung with the hanging ring 301 to support the pedal 30, which ensures the safety in use, and also reduces the stress on the output end of the linear motor 3 to prevent the pedal 30 from tilting due to stress deformation.
[0040] After the slag screen 23 is cleaned, the staff leaves the position of the footboard 30, and the linear motor 3 is started to move the footboard 30 back. Since the lower end surface of the scraper 31 is in contact with the upper end surface of the footboard 30, the scraper can scrape the residual material on the upper end surface of the footboard 30 during the movement of the footboard 30 back. Due to the setting of the hanging ring 301, the footboard 30 does not need to be moved back completely, but only needs to leave enough space for the slag rack 2 to move downward. In this way, the scraped and accumulated residual material can be cleaned together when the slag screen 23 is cleaned next time.
[0041] Finally, the linear motor 3 is turned off, and the driving motor 22 is started. The screw-coupled slag rack 2 is driven by the screw rod 221 to move downward under the limiting and contacting state of the first guide plate 24. During the movement, the second guide plate 51 also assists in limiting and contacting. When the slag rack 2 is moved to the position, the second guide plate 51 still contacts with the slag rack 2. During the whole process, the slag rack 2 moves in a vertical state.
[0042] It should be noted that in the present embodiment, in order to not block the cleaning of the slag screen 23, the connecting rod 210 should be provided with two, and the first guide plate 24 should also be adapted to be symmetrically provided with two left and right, leaving a space for the impurities to fall between the two first guide plates 24. Similarly, in order to ensure the stability of use, the pull rope 111 should be provided with two, and the hook 112 and the hanging ring 301 should also be adapted to be provided with two, so that the footboard 30 is evenly stressed and is not easy to be inclined and deviated, ensuring the safety of the staff in use. When the footboard 30 is moved back, the hook 112 does not need to be removed from the hanging ring 301. When used next time, with the extension of the footboard 30, the pull rope 111 is straightened to play a supporting role.
