Description

Technical Field

[0001] This utility model belongs to the field of protective device technology, and in particular relates to a dustproof and rainproof cover device for a gate opening and closing machine room. Background Technology

[0002] Currently, during the construction of sluice gate lever-type hoist rooms, the lever rises as the gate is lifted. Because the hoist room's height is insufficient, a hole needs to be pre-drilled in the roof to allow the lever to extend beyond it. This allows rainwater and dust to enter the hoist room through this hole. The hoist room typically houses numerous electronic devices for gate opening and closing control; some sluice gate management rooms are even located within the hoist room, along with intelligent management equipment such as video surveillance. The rainwater and dust entering the room through the lever hole deteriorate the internal environment, affecting the normal operation of the facilities.

[0003] In summary, it is necessary to design a dustproof and rainproof device that does not affect the opening and closing operation of the gate in order to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dustproof and rainproof cover device for the opening and closing machine room, which can be linked with the gate screw to achieve the effect of dustproof and rainproof without affecting the gate opening and closing operation, and prevent rainwater and dust from entering the machine room.

[0005] The technical solution adopted by this utility model is as follows: a dustproof and rainproof cover device for a gate operating room, including a base fixedly connected to the top surface of the gate operating room and a top cover located above the base. An annular base is provided on the base, and a waterproof canvas sleeve is provided between the base and the top cover. The upper end of the waterproof canvas sleeve is fixedly connected to the edge of the top cover, and the lower end of the waterproof canvas sleeve is fixedly connected to the annular base. A bearing seat is provided in the middle of the bottom surface of the top cover, and a ball bearing is installed in the bearing seat. The upper end of the gate screw passes through a window provided in the middle of the base and enters the interior of the waterproof canvas sleeve, and the upper end of the gate screw is fixedly connected to the inner ring of the ball bearing. An anti-torsion structure is also provided between the base and the top cover.

[0006] Preferably, the anti-torsion structure includes multiple connecting seats on the bottom surface of the top cover, with a lifting guide rod extending downward in the axial direction installed on each connecting seat, and multiple guide holes provided at corresponding positions on the inner edge of the base, with the lower part of each lifting guide rod located in each guide hole respectively.

[0007] Preferably, multiple support rings are provided inside the waterproof canvas sleeve along the axial direction, and the outer surface of each support ring is fixedly connected to the inner wall of the waterproof canvas sleeve.

[0008] Preferably, an annular wing plate extending downward is provided at the edge of the top cover, and a groove is provided on the inner wall of the annular wing plate. The upper end of the waterproof canvas sleeve is located inside the annular wing plate and is fixedly connected by an elastic retaining ring embedded in the groove.

[0009] Preferably, the lower end of the waterproof canvas sleeve is fitted onto the outside of the annular base and fixedly connected by a clamp.

[0010] Preferably, it also includes a sealing gasket, which comprises a horizontal sealing gasket and a downwardly extending sealing sleeve. The sealing gasket is located between the base and the top surface of the hoisting machine room, and the sealing sleeve is inserted into the screw hole on the top surface of the hoisting machine room.

[0011] The advantages and positive effects of this utility model are:

[0012] This utility model provides a dustproof and rainproof cover device for a gate control room. It is installed on a pre-drilled screw hole in the ceiling of the gate control room, effectively sealing the screw hole and preventing rainwater and dust from entering the room, thus ensuring the normal operation of the facilities inside. The dustproof and rainproof cover device positions the upper end of the gate screw within a waterproof canvas sleeve, and the upper end of the gate screw is connected to the top cover via a bearing. During the lifting and lowering movement of the gate screw, the top cover and the gate screw move synchronously, causing the waterproof canvas sleeve to extend and retract, continuously keeping the screw hole closed. Because the upper end of the gate screw is connected to the top cover via a bearing and an anti-torsion structure is installed between the top cover and the base, the top cover only moves synchronously without rotating during the lifting and lowering movement of the gate screw. This effectively prevents the waterproof canvas sleeve from twisting, thus preventing tearing and extending its service life. Attached Figure Description

[0017] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0018] Please see Figure 1 and Figure 2 The dustproof and rainproof cover device for the hoisting machine room of this utility model includes a base 11 fixedly connected to the top surface 14 of the hoisting machine room and a top cover 4 located above the base 11. An annular base 15 is provided on the base 11. A waterproof canvas sleeve 9 is provided between the base 11 and the top cover 4. The upper end of the waterproof canvas sleeve 9 is fixedly connected to the edge of the top cover 4, and the lower end of the waterproof canvas sleeve 9 is fixedly connected to the annular base 15.

[0019] A bearing seat 3 is provided in the middle of the bottom surface of the top cover 14, and a ball bearing 2 is installed in the bearing seat 3. The upper end of the gate screw 8 passes through the window in the middle of the base 11 and enters the interior of the waterproof canvas sleeve 9, and the upper end of the gate screw 8 is fixedly connected to the inner ring of the ball bearing 2. When the gate screw 8 moves up and down, the top cover 4 moves up and down synchronously with the gate screw 8. Since the top end of the gate screw 8 is connected to the top cover 4 through the ball bearing 2, the top cover 4 and the gate screw 8 can rotate relative to each other.

[0020] In this embodiment, a downwardly extending annular wing plate is provided at the edge of the top cover 4, and a groove is provided on the inner wall of the annular wing plate. The upper end of the waterproof canvas sleeve 9 is located inside the annular wing plate and is fixedly connected by an elastic retaining ring 1 embedded in the groove. In this embodiment, the lower end of the waterproof canvas sleeve 9 is sleeved on the outside of the annular base 15 and is fixedly connected by a clamp 10. In this way, the upper end of the waterproof canvas sleeve 9 and the top cover 4, and the lower end of the waterproof canvas sleeve 9 and the annular base 15 are detachably connected, so that the waterproof canvas sleeve 9 can be replaced when it ages or is damaged.

[0021] In this embodiment, multiple support rings 7 are provided inside the waterproof canvas sleeve 9 along the axial direction. The outer surface of each support ring 7 is fixedly connected to the inner wall of the waterproof canvas sleeve 9. Specifically, the outer surface of the support ring 7 and the inner wall of the waterproof canvas sleeve 9 can be fixedly connected by adhesive. The function of providing multiple support rings 7 is to support the waterproof canvas sleeve 9, preventing frictional contact between the waterproof canvas sleeve 9 and the internal gate screw 8 when the waterproof canvas sleeve 9 retracts downwards. Multiple support rings 7 also enhance the overall structural strength of the waterproof canvas sleeve 9. The support rings 7 can be stainless steel rings or aluminum alloy rings.

[0022] An anti-torsion structure is also provided between the base 11 and the top cover 4. By setting the anti-torsion structure, the top cover 4 can be effectively prevented from rotating, thereby preventing the waterproof canvas sleeve 9 from torturing. This can prevent the waterproof canvas sleeve 9 from tearing or aging due to torsion, and can improve the service life of the waterproof canvas sleeve 9.

[0023] As shown in the figure, the anti-torsion structure includes multiple connecting seats 5 disposed on the bottom surface of the top cover 4. Each connecting seat 5 is equipped with a lifting guide rod 6 extending downwards in the axial direction. Multiple guide holes are provided at corresponding positions on the inner edge of the base 11, with the lower part of each lifting guide rod 6 located within its respective guide hole. In this embodiment, each connecting seat 5 has a threaded connection hole in its center, and a threaded portion is provided at the upper end of the lifting guide rod 6. The upper end of the lifting guide rod 6 is threadedly connected to the connecting seat 5.

[0024] It also includes a sealing gasket 12, which consists of a horizontal sealing gasket and a downwardly extending sealing sleeve. The sealing gasket is located between the base 11 and the top surface 14 of the hoisting machine room, and the sealing sleeve is inserted into a pre-drilled screw hole on the top surface 14 of the hoisting machine room. The purpose of setting the sealing gasket 12 is to improve the sealing effect between the base 11 and the top surface 14 of the hoisting machine room, preventing rainwater and dust from entering the machine room through this location.

[0025] like Figure 1 As shown, multiple mounting holes are provided around the lead screw hole on the top surface 14 of the gate hoist room, and multiple threaded mounting holes are provided at the corresponding positions on the base 11. During installation, multiple mounting screws 13 pass through the mounting holes on the top surface 14 of the gate hoist room from bottom to top and their upper ends are screwed into the threaded mounting holes on the base 11.

[0026] How to use:

[0027] Assemble the various components of this dustproof and rainproof cover, insert the upper end of the gate screw 8 into the waterproof canvas sleeve 9 and fix the upper end of the gate screw 8 to the inner ring of the ball bearing 2. Then, place a sealing gasket 12 in the screw hole on the top surface 14 of the hoisting room, press the base 11 on top of the sealing gasket 12, and then fix the base 11 to the top surface 14 of the hoisting room from below using multiple mounting screws 13. During operation, as the gate screw 8 rises, the top cover 4 rises synchronously but will not rotate under the action of the anti-torsion structure. The waterproof canvas sleeve 9 gradually extends upward. As the gate screw 8 lowers downward, the top cover 4 lowers synchronously but will not rotate. The waterproof canvas sleeve 9 gradually contracts and stacks downward.
