Description

Technical Field

[0001] This utility model relates to the technical field of covering pit devices, specifically horizontal pit covers. Background Technology

[0002] With the continuous expansion of urban construction and the rapid development of industrial technology, underground pits, as key facilities such as underground garbage stations and maintenance wells, are increasingly widely used in the construction and infrastructure fields. These pits not only play an important functional role but also directly relate to the safety and efficiency of urban operations. However, traditional pit cover designs have revealed many shortcomings in practical applications, making it difficult to meet the stringent requirements of modern urban management and industrial production.

[0003] First, poor sealing is a major drawback of traditional pit cover designs. Due to the poor sealing performance between the cover and the edge of the pit, debris, dust, and even moisture can easily seep into the pit. This not only threatens the operation of equipment inside the pit but may also cause environmental sanitation problems, affecting the city's image and the quality of life of residents.

[0004] Secondly, inconvenient operation is a major drawback of traditional pit cover design. The traditional manual opening and closing method is not only time-consuming and labor-intensive, but also particularly inadequate when dealing with large pits or requiring frequent operation. Furthermore, this manual operation method increases the workload of workers and raises safety risks, especially in complex and changing construction environments, posing numerous hidden dangers.

[0005] Furthermore, low safety is also one of the problems that traditional pit cover designs urgently need to solve. Although existing electric cleaning station pit covers use power sources such as electric push rods to lift the covers, the maximum angle between the covers and the ground after lifting is often no more than 90 degrees. This design not only fails to effectively avoid creating indoor obstacles, but also increases the risk of workers tripping, especially in dimly lit or complex environments, where the safety hazards are particularly prominent.

[0006] In addition, severe friction and wear is a major drawback of traditional pit cover designs. During the sliding process, due to the lack of effective guiding and buffering mechanisms, the cover is prone to severe friction with the internal structure of the pit. Especially when the cover is set horizontally, the direct contact between its front end and the top of the garbage bin exacerbates the wear phenomenon, which not only shortens the service life of the equipment but also significantly increases maintenance costs.

[0007] Finally, excessive noise is another problem that cannot be ignored in the design of traditional pit covers. During opening and closing, due to the lack of effective vibration reduction and sound insulation measures, traditional covers often produce ear-piercing noise, which not only affects the aesthetics and tranquility of the surrounding environment, but may also have a negative impact on the mental health of the staff. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] In view of the shortcomings of the existing technology, this utility model provides a horizontal pit cover.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution: The horizontal pit cover of this utility model includes a baffle body, wherein multiple baffle bodies are provided and arranged in a rectangular structure. Each baffle body includes a receiving box, a cover plate, and a driving assembly. The receiving box has a receiving groove, and the bottom of the receiving groove has an adjustment groove. The driving assembly includes a drive motor and a threaded screw. The drive motor is fixedly installed at the rear end of the adjustment groove, and the threaded screw is rotatably installed in the adjustment groove. The output end of the drive motor is connected to the threaded screw. The cover plate is slidably installed in the receiving groove, and the rear end of the cover plate is sleeved on the threaded screw via a slider. Sliding grooves are provided on both sides of the receiving groove, and the two sides of the cover plate are slidably connected to the sliding grooves.

[0012] Preferably, the sides of the cover plate are wrapped with rubber pads.

[0013] More preferably, the sides of the receiving box have a sloping structure.

[0014] Preferably, the receiving trough has a sloping structure, and the slope of the receiving trough is 0-15 degrees.

[0015] Preferably, guide wheels are embedded in the top and bottom of the receiving groove, and the guide wheels are rotatably installed in the receiving groove.

[0016] More preferably, the guide wheel is covered with a cushioning rubber pad.

[0017] Preferably, the surfaces of the cover plate and the receiving box are provided with anti-slip textures.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a horizontal pit cover, which has the following beneficial effects:

[0020] Rectangular structure, comprehensive coverage:

[0021] The horizontal pit cover is mainly composed of multiple baffle bodies, which surround to form a rectangular structure that can completely cover the pit, ensuring the pit's safety, closure, and aesthetics.

[0022] Modular design for easy maintenance:

[0023] Each baffle body includes a receiving box, a cover plate, and a drive assembly. This modular design not only simplifies the installation process but also facilitates later maintenance and component replacement, improving the reliability and service life of the equipment.

[0024] The high efficiency and convenience of the drive system

[0025] Motor-driven, automated operation:

[0026] The drive assembly consists of a drive motor and a lead screw, installed in the adjustment slot of the receiving box. The rotation of the drive motor drives the lead screw, which in turn drives the cover plate to slide within the receiving slot, thus opening and closing the cover plate. This design makes operation simpler and faster, reduces manual intervention, and improves work efficiency.

[0027] Parallel deployment reduces safety hazards:

[0028] Compared to traditional electric cleaning station pit covers (which typically use electric push rods or other power sources to flip up the traditional cover, with the maximum angle between the flipped cover and the ground not exceeding 90 degrees), the cover of this utility model unfolds parallel or is stored in the tray, reducing the safety hazards caused by indoor obstacles created by the traditional cover flipping up at 90 degrees and improving on-site safety.

[0029] Improve sealing performance:

[0030] The rubber gaskets wrapped around the sides of the cover plate effectively increase the seal between the cover plate and the edge of the pit, effectively preventing debris, dust or moisture from entering the pit and keeping the inside of the pit clean and dry.

[0031] Reduce noise:

[0032] The rubber gasket not only improves the seal but also significantly reduces noise when the cover is opened and closed, providing users with a quieter working environment.

[0033] Enhance construction safety:

[0034] The sloping design on the sides of the tray box avoids obstruction caused by the protrusion of the tray box, reduces safety hazards during construction, such as tripping, and improves the safety of the construction site.

[0035] Reduce friction and wear:

[0036] The sloping structure of the collection trough ensures that the cover maintains a certain gap with the garbage bin in the pit when it is opened, preventing friction. At the same time, the guide wheels embedded in the collection trough further guide the cover to slide smoothly, reducing friction and wear and extending the cover's service life.

[0037] Improve operational stability:

[0038] The buffer pads wrapped around the guide wheel not only reduce friction and noise between the cover plate and the guide wheel, but also increase the wear resistance of the guide wheel, making the operation more stable and reliable.

[0039] Increase aesthetics:

[0040] The anti-slip texture on the surface of the cover and tray not only improves stability during operation, but also gives the product a more aesthetically pleasing appearance and enhances the overall user experience. Attached Figure Description

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figure 1-3 The present invention relates to a horizontal pit cover, comprising a baffle body, wherein multiple baffle bodies are provided and arranged in a rectangular structure. The baffle body includes a receiving box 1, a cover plate 2, and a driving assembly. The receiving box 1 has a receiving groove 3, and the bottom of the receiving groove 3 has an adjustment groove 4. The driving assembly includes a driving motor 6 and a threaded screw 5. The driving motor 6 is fixedly installed at the rear end of the adjustment groove 4, and the threaded screw 5 is rotatably installed in the adjustment groove 4, with the output end of the driving motor 6 connected to the threaded screw 5. The cover plate 2 is slidably installed in the receiving groove 3, and the rear end of the cover plate 2 is sleeved on the threaded screw 5 via a slider 9. The receiving groove 3 has sliding grooves 7 on both sides, and the two sides of the cover plate 2 are slidably connected to the sliding grooves 7.

[0047] This horizontal pit cover is mainly composed of multiple baffle bodies that form a rectangular structure to cover the pit. Each baffle body includes a receiving box 1, a cover plate 2, and a drive assembly. The drive assembly (composed of a drive motor 6 and a threaded screw 5) is installed in the adjustment groove 4 of the receiving box 1. The rotation of the drive motor 6 drives the threaded screw 5 to rotate, which in turn drives the cover plate 2 to slide in the receiving groove 3, thus opening and closing the cover plate 2. Compared with traditional pit covers, existing electric cleaning station pit covers use electric push rods or other power sources to flip up the traditional cover plate. After flipping up, the maximum angle with the ground does not exceed 90 degrees, creating an indoor obstacle and causing safety hazards. This design allows the cover plate 2 to unfold horizontally or be stored in the receiving groove 3, reducing the safety hazards caused by the indoor obstacle created by the traditional cover plate flipping up at 90 degrees.

[0048] Working principle of the preferred technical solution

[0049] The cover plate has 10 rubber pads wrapped around its two sides.

[0050] Working principle: Wrapping the side of the cover plate 2 with rubber pads 10 can increase the sealing between the cover plate 2 and the edge of the pit, prevent debris or water from entering the pit, and reduce the noise when the cover plate 2 is opened and closed.

[0051] The side of the receiving box 1 has a sloping structure.

[0052] Working principle: The sides of the collection box 1 are designed as a sloping structure, so that the collection box 1 has a buffer slope when it is arranged around the pit, so as to avoid the protrusion of the collection box 1 from causing obstruction, affecting the construction operation or easily tripping the workers.

[0053] The receiving trough 3 has a sloping structure.

[0054] Working principle: The receiving trough 3 is designed as a sloping structure (slope of 0-15 degrees). When the cover plate 2 is extended and opened, the slope design of the receiving trough 3 makes the front end of the cover plate 2 abut against the garbage bin in the pit, so that there is a certain gap between the cover plate 2 and the top of the garbage bin in the pit. This avoids the phenomenon that the cover plate 2 would easily rub against the top of the garbage bin in the pit when it is opened or closed if the cover plate 2 is set horizontally.

[0055] 3-board groove with embedded guide wheel 8

[0056] Working principle: Guide wheels 8 are embedded in the top and bottom of the receiving groove 3. The guide wheels 8 are rotatably installed in the receiving groove 3, which can guide the cover plate 2 to maintain a stable trajectory during the sliding process, reduce friction and wear, and improve the service life of the cover plate 2.

[0057] The guide wheel 8 is wrapped with a buffer pad 10.

[0058] Working principle: Wrapping the guide wheel 8 with a buffer pad 10 can further reduce the friction and noise between the cover plate 2 and the guide wheel 8, while increasing the wear resistance of the guide wheel 8 and extending its service life.

[0059] The surfaces of cover plate 2 and receiving box 1 are provided with anti-slip texture.

[0060] Working principle: Anti-slip textures are set on the surface of cover plate 2 and receiving box 1, which can increase the stability during operation, prevent safety accidents caused by slipping hands or feet, and improve the overall aesthetics.

[0061] In summary, all the preferred technical solutions for horizontal pit covers are designed to improve the operating efficiency, sealing performance, wear resistance, and safety of the cover 2, thereby meeting the usage requirements in different scenarios.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
