Description

Technical Field

[0001] The invention belongs to the technical field of safety management of pool roof openings, and in particular relates to a hydraulically opened opening cover plate for preventing a pool roof from falling. Background Art

[0002] The safety management of the openings on the top of the pool has always been an important concern, especially in sewage treatment plants, water supply plants, and industrial water pools. These pools are usually equipped with openings for material addition, operation and maintenance, or observation of the pool conditions, and the cover of the opening is a key component to ensure the safety of these operations. Traditional covers generally have the following problems: the design fails to fully consider the drainage needs, and rainwater or other liquids can easily penetrate into the hole, affecting the water quality in the pool or the normal operation of the equipment; the material selection is not flexible enough, and it is difficult to meet various working conditions and environmental requirements; some are directly placed on the groove of the opening, although it can play a basic sealing role, but due to its heavy weight, it is easy to be dragged down the pool by the cover due to insufficient strength when operated by a single person, resulting in safety accidents; some use a slide rail type, which has certain requirements for the space around the opening after opening, and cannot be applied to many small areas; some openings are low from the standing operating surface, and there is a risk of people falling after opening the cover; the opening of the top of the pool stipulates that two people must operate at the same time, but this measure only relies on regulations and lacks structural guarantees, and safety hazards still exist. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a hydraulically openable hole cover for preventing a pool top from falling, so as to solve the deficiencies in the prior art.

[0004] In order to achieve the above object, the present invention is achieved through the following technical solutions:

[0006] As described in the hydraulically opened hole cover for preventing the top of a pool from falling, the edge protection mechanism is automatically lifted up as the cover is opened to form a semi-closed protection structure.

[0007] As described in the hydraulically opened hole cover for preventing the top of a pool from falling, the edge protection mechanism includes a horizontal guardrail, both ends of the horizontal guardrail are fixedly connected to the concrete hole through folding hinges, and one end of the horizontal guardrail is hinged to the cover through a hinge.

[0008] As described in the hydraulic opening hole cover for preventing a pool from falling, the handle mechanism includes a semicircular hidden handle, the cover is provided with a rotating shaft, the bottom frame is provided with a slot corresponding to the position of the hidden handle, and the hidden handle is hidden in the slot after being horizontally rotated around the rotating shaft.

[0009] As described in the hydraulically openable hole cover for preventing a pool top from falling, wherein the cover has a replaceable surface layer.

[0010] As described in the hydraulic opening hole cover for preventing the top of a pool from falling, a mother-child drainage trough is provided at the joint of two mutually spliced ​​cover plates.

[0011] The beneficial effects of the technical solution of the present invention are:

[0012] 1. This anti-fall hydraulic opening hole cover on the top of the pool is specially designed to enhance the safety of the pool hole area. It uses high-strength stainless steel as the main material to ensure the stability of the structure and is suitable for working conditions containing slightly corrosive liquids and gases in the pool;

[0013] 2. The cover surface can be flexibly replaced to adapt to different environmental requirements, and supports the embedding of solar panels to realize the use of green energy as a power source for opening the hole;

[0014] 3. In the design of the cover structure, the drainage needs are fully considered to effectively prevent rainwater from flowing into the cave;

[0015] 4. To further improve safety, a two-person operating handle mechanism is set up to ensure that only two operators can open the cover at the same time, effectively avoiding possible misoperation or safety risks caused by single-person operation, greatly improving the safety factor of the work site;

[0016] 5. When the cover is successfully opened, the built-in edge protection guardrail at the opening will lift the cover into place to form a semi-enclosed protection area, effectively reducing the risk of personnel falling during observation or operation. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0030] See also Figures 1 to 3As shown, in a preferred embodiment, the anti-fall hydraulic opening hole cover for the top of the pool of the present invention is suitable for holes with material addition, operation and maintenance, or observation of the conditions in the pool. It can be arranged in a single piece or in pairs according to the size of the hole, including a cover 1 and a bottom frame 2. The bottom frame 2 is fixedly connected to the concrete hole, one side of the cover 1 is hinged to the bottom frame 2, and the edges of the opposite sides of the cover 1 are provided with a damping hydraulic rod 3, an edge protection mechanism, and a handle mechanism. The cover 1, the bottom frame 2, and the damping hydraulic rod 3 are all made of stainless steel. The use of stainless steel can be applied to working conditions containing slightly corrosive liquids and gases in the pool. The cover 1 is opened and closed upwards smoothly and reliably through the damping hydraulic rod 3.

[0031] The edge protection mechanism automatically rises as the cover plate 1 is opened and forms a semi-enclosed protection structure, thereby realizing linkage with the cover plate 1. Figure 2 , Figure 3 As shown, the edge protection mechanism includes a horizontal guardrail 4, both ends of which are fixedly connected to the concrete hole through folding hinges, and one end of the horizontal guardrail 4 is hinged to the cover plate 1 through a hinge, so that the guardrail can be folded and hidden in the hole when the cover plate 1 is closed.

[0032] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the handle mechanism includes a semicircular hidden handle 5, the cover plate 1 is provided with a rotation axis 6, and the bottom frame 2 is provided with a slot 7 corresponding to the position of the hidden handle 5. The hidden handle 5 rotates horizontally around the rotation axis 6 and then hides in the slot 7. The hidden handle 5 rotates through the semicircular handle, so that when the cover plate 1 is closed, the handle is rotated inward and locked in the reserved slot of the bottom frame 2. Since the hidden handle 5 is provided on both sides of the cover plate 1, when one person operates, only one side of the handle can be unlocked, and the cover plate 1 cannot be opened normally. Two people must be on both sides at the same time to rotate the handle outward to unlock the cover plate 1 and lift it upward, effectively avoiding possible misoperation or safety risks when a single person operates, thereby realizing a double-operation handle mechanism.

[0033] The damping stainless steel hydraulic rod is selected according to the weight and opening degree requirements of the cover plate 1, and the installation position is finally determined.

[0034] The cover 1 has a replaceable surface layer. The top of the cover 1 supports the surface layer by means of snaps and the like, and can be flexibly replaced, such as plastic wood boards, solar panels, etc., to adapt to different environmental requirements, while realizing the use of green energy as a power source for opening the hole.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, a mother-child drainage trough 8 is provided at the joint of two cover plates 1 spliced ​​to each other. When the two cover plates 1 of the opening are spliced, the mother-child drainage trough 8 can quickly discharge the leaked rainwater from both sides.

[0036] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
