Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of protective devices, in particular to a large composite storage tank roof protection device. BACKGROUND

[0002] The common oil storage tank is mainly a vertical cylindrical tank, which is divided into fixed dome roof tank and floating roof storage tank according to the structure of the tank top. The inner floating roof storage tank is formed by adding a floating roof inside the fixed dome roof tank. The floating roof added in the tank can reduce the volatilization loss of the medium, and the inner floating roof effectively isolates the liquid in the tank and the air, which can reduce the risk level of fire and explosion to a certain extent. The outer dome roof can prevent rainwater, snow and dust from entering the tank, ensuring the cleanliness of the medium in the tank. However, the storage tank needs to be protected by a protective device when it is placed.

[0003] Some existing storage tanks are prone to continuously attaching debris to the top after being placed for a long time, and the height of the storage tank is relatively high. Therefore, the operator needs to climb to a high place to clean the tank top when cleaning the tank top, which is relatively troublesome. Therefore, we propose a large composite storage tank roof protection device to solve the above-mentioned problems. SUMMARY

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present application and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the title of the invention to avoid obscuring the purpose of this section, the abstract of the specification and the title of the invention, and such simplifications or omissions cannot be used to limit the scope of the present application.

[0005] Therefore, the purpose of the present application is to provide a large composite storage tank roof protection device, which can solve the problem that the existing storage tank is prone to continuously attaching debris to the top after being placed for a long time, and the height of the storage tank is relatively high. Therefore, the operator needs to climb to a high place to clean the tank top when cleaning the tank top, which is relatively troublesome.

[0006] To solve the above technical problems, the present application provides a large composite storage tank roof protection device, which adopts the following technical scheme: a protection mechanism is provided, which includes a tank body and a protection cover, a plurality of insertion slots are arranged on the outer wall of the upper end of the tank body in a circumferential direction, a plurality of grooves are arranged on the inner side of the protection cover, an insertion plate is movably arranged in the groove, one end of the insertion plate is connected with the inner wall of the groove through a spring, and the other end of the insertion plate is inserted into the insertion slot.

[0007] A cleaning mechanism includes a rotating shaft vertically inserted into the top of a protective cover. The upper end of the rotating shaft passes through the protective cover and is fixedly provided with a plurality of first fan blades. A bearing is fixedly inserted into the top of the inner wall of the protective cover. The rotating shaft passes through the protective cover and is fixedly inserted into the bearing. A cleaning plate is fixedly sleeved on the rotating shaft. When the rotating shaft rotates, the cleaning plate scrapes the protective cover.

[0008] By adopting the above technical solution, this solution uses wind power to drive the first fan blade and the rotating shaft to rotate. At the same time, the cleaning plate follows the rotating shaft to clean the debris on the top of the protective cover, thereby reducing the possibility of debris accumulating on the top of the protective cover and making it more convenient to clean the protective cover.

[0009] Optionally, the inner wall of the protective cover is provided with a plurality of connecting rods, and a motor is fixedly connected to one end of each connecting rod away from the inner wall of the protective cover. The inner wall of the protective cover is provided with guide blocks corresponding to the number of insert plates. A take-up reel is fixedly connected to the lower end of the motor's rotating shaft. A steel cable corresponding to the number of insert plates is wound on the take-up reel. The end of the steel cable away from the take-up reel passes through the guide block and is fixedly connected to the insert plate. The motor is fixed inside the protective cover by the cooperation of the plurality of connecting rods.

[0010] By adopting the above technical solution, when the motor is running, it drives the winding reel to rotate and wind up the steel cable. At the same time, the guide block guides the steel cable. At this time, the steel cable pulls the insert plate to move and separate it from the slot, which makes it easy for the operator to disassemble the protective cover.

[0011] Optionally, the top of the motor is provided with an electric push rod, and the extended end of the electric push rod is provided with several insert rods. When the electric push rod pushes the insert rods upward, the insert rods insert upward into the lower end of the rotating shaft and limit the rotation shaft.

[0012] By adopting the above technical solution, this solution uses an electric push rod to push the insertion rod upward and connect it to the rotating shaft, thereby reducing the possibility of the rotating shaft rotating. When the electric push rod drives the insertion rod downward, it separates from the rotating shaft. At this time, the wind power can drive the first fan blade and the rotating shaft to rotate.

[0013] Optionally, the insert plate includes a movable plate and a connecting plate. One end of the movable plate is inserted into the groove and connected to the inner wall of the groove by a spring. The connecting plate is fixedly connected to the other end of the movable plate. The end of the steel cable away from the winding reel passes through the guide block and is fixedly connected to the connecting plate.

[0014] By adopting the above technical solution, when the motor is running, it drives the winding reel to rotate and wind up the steel cable. At this time, the connecting plate and the movable plate are moved by the steel cable and separated from the slot, thereby causing the protective cover to lose its limit and making it easier for the operator to disassemble the protective cover.

[0015] Optionally, a compression spring is fixedly connected to the bottom of the inner wall of the slot, and a top plate is fixedly connected to the upper end of the compression spring. The upper end of the top plate abuts against the bottom surface of the insert plate, and the top plate is L-shaped.

[0016] By adopting the above technical solution, this solution facilitates the upward movement of the insert plate and the protective cover by cooperating with the compression spring and the top plate. When the protective cover is impacted, the protective cover drives the insert plate downward, and at this time the compression spring buffers the impact force.

[0017] Optionally, the protective cover includes a semi-circular cover and a first circular tube. The first circular tube is fixedly connected to the lower end of the semi-circular cover. A circular ring is fixedly connected to the lower end of the first circular tube. The groove is formed inside the circular ring. A second circular tube is fixedly sleeved on the outer wall of the circular ring. A storage groove is formed between the first circular tube and the second circular tube.

[0018] By adopting the above technical solution, this solution uses a semi-circular cover to protect the top of the tank and a collection trough to collect the debris scraped off by the cleaning plate, thus facilitating the operator to clean up the debris in a unified manner later.

[0019] Optionally, the cleaning plate includes four scrapers, each with one end fixedly connected to a rotating shaft. The scrapers are arc-shaped, and when the rotating shaft rotates, the scrapers rotate synchronously and scrape the outer wall of the protective cover.

[0020] By adopting the above technical solution, this solution uses wind power to drive the first fan blade and the rotating shaft to rotate. At this time, the four scrapers rotate simultaneously with the rotating shaft, and the scrapers facilitate the scraping of debris on the outer wall of the protective cover.

[0021] Optionally, the lower end of the rotating shaft passes through a protective cover and is fixedly provided with several second fan blades.

[0022] By adopting the above technical solution, when the shaft rotates, it drives the second fan blade to rotate. At this time, the rotation of the second fan blade increases the airflow speed inside the protective cover, thereby heat dissipating the protective cover.

[0023] In summary, the present invention has at least one of the following beneficial effects: 1. The tank is relatively tall, so the wind force at the top of the tank is relatively strong. At this time, the wind force drives the first fan blade and the rotating shaft to rotate. At the same time, the cleaning plate follows the rotating shaft to rotate and sweeps away the debris on the top of the protective cover, thereby reducing the possibility of debris accumulating on the top of the protective cover and making it more convenient to clean the protective cover.

[0024] 2. When the motor is running, it drives the winding reel to rotate and wind up the steel cable. At the same time, the guide block guides the steel cable. At this time, the steel cable pulls the insert plate to move and separate it from the slot, which makes it easier for the operator to disassemble the protective cover. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0033] Example 1, refer to Figures 1-4 In this embodiment, to address the problem that existing storage tanks tend to accumulate debris on their tops after prolonged storage, and that the tanks are relatively tall, requiring operators to climb to higher ground for cleaning, making the process cumbersome, this invention discloses a protective device for the top of large composite storage tanks.

[0034] The system includes a protective mechanism 100, which comprises a tank 101 and a protective cover 102. The protective cover 102 includes a semi-circular cover 102a1 and a first circular tube 102a2. The first circular tube 102a2 is fixedly connected to the lower end of the semi-circular cover 102a1. A circular ring 102a3 is fixedly connected to the lower end of the first circular tube 102a2. A groove 104 is formed inside the circular ring 102a3. A second circular tube 102a4 is fixedly sleeved on the outer wall of the circular ring 102a3. A collection groove 102a5 is formed between the first circular tube 102a2 and the second circular tube 102a4. The semi-circular cover 102a1 is used to protect the top of the tank 101, and the collection groove 102a5 is used to collect the debris scraped off by the cleaning plate 204, thereby facilitating the operator to clean up the debris in a unified manner later.

[0035] The outer wall of the upper end of the tank 101 is provided with a number of slots 103 distributed around its circumference. The inner side of the protective cover 102 is provided with a number of grooves 104. An insert plate 105 is movably disposed in the groove 104. One end of the insert plate 105 is connected to the inner wall of the groove 104 by a spring 106. The other end of the insert plate 105 is inserted into the slot 103. First, the protective cover 102 is hoisted onto the tank 101. Then, the spring 106 pushes the insert plate 105 to move and insert it into the slot 103, thereby fixing the protective cover 102 to the upper end of the tank 101. The protective cover 102 then protects the top of the tank 101.

[0036] The cleaning mechanism 200 includes a rotating shaft 201 vertically inserted into the top of the protective cover 102. The upper end of the rotating shaft 201 passes through the protective cover 102 and is fixedly provided with several first fan blades 202. The tank 101 is relatively high, so the wind force at the top of the tank 101 is relatively large. At this time, the wind force drives the first fan blades 202 and the rotating shaft 201 to rotate.

[0037] A bearing 203 is fixedly inserted into the top of the inner wall of the protective cover 102. The rotating shaft 201 passes through the protective cover 102 and is fixedly inserted into the bearing 203. The bearing 203 helps to increase the stability of the rotating shaft 201 when it rotates.

[0038] A cleaning plate 204 is fixedly sleeved on the rotating shaft 201. When the rotating shaft 201 rotates, the cleaning plate 204 scrapes the protective cover 102. The cleaning plate 204 includes four scrapers, and the opposite ends of the four scrapers are fixedly connected to the rotating shaft 201. The scrapers are arc-shaped. When the rotating shaft 201 rotates, the scrapers rotate synchronously and scrape the outer wall of the protective cover 102. The first fan blade 202 and the rotating shaft 201 are rotated by wind power. At this time, the four scrapers rotate with the rotating shaft 201. The scrapers facilitate the scraping of debris on the outer wall of the protective cover 102, making it more convenient to clean the outer wall of the protective cover 102.

[0039] The lower end of the rotating shaft 201 passes through the protective cover 102 and is fixedly provided with several second fan blades 205. When the rotating shaft 201 rotates, it drives the second fan blades 205 to rotate. At this time, the rotation of the second fan blades 205 increases the air flow speed inside the protective cover 102, thereby dissipating heat from the protective cover 102 and reducing the heat at the top of the tank 101.

[0040] The specific working principle is as follows: The tank body 101 is relatively high, so the wind force at the top of the tank body 101 is relatively strong. At this time, the wind force drives the first fan blade 202 and the rotating shaft 201 to rotate. At the same time, the cleaning plate 204 rotates with the rotating shaft 201 and cleans the debris on the top of the protective cover 102, thereby reducing the possibility of debris accumulating on the top of the protective cover 102 and making it more convenient to clean the protective cover 102.

[0041] Example 2, refer to Figures 2-4 In this embodiment, in order to solve the problem that the disassembly of some existing protective devices is relatively troublesome, based on the same concept as in Embodiment 1 above, the large composite material storage tank top protective device further includes:

[0042] The inner wall of the protective cover 102 is provided with a plurality of connecting rods 102a. A motor 102b is fixedly connected to one end of each connecting rod 102a away from the inner wall of the protective cover 102. Guide blocks 102c, corresponding to the number of insert plates 105, are provided on the inner wall of the protective cover 102. A take-up reel 102d is fixedly connected to the lower end of the rotating shaft of the motor 102b. Steel cables 102e, corresponding to the number of insert plates 105, are wound on the take-up reel 102d. The steel cables 102e are located away from the take-up reel 102d. One end passes through the guide block 102c and is fixedly connected to the insert plate 105. Several connecting rods 102a cooperate with the side to fix the motor 102b inside the protective cover 102. When the motor 102b runs, it drives the winding reel 102d to rotate and wind up the steel cable 102e. At the same time, the guide block 102c guides the steel cable 102e. At this time, the steel cable 102e pulls the insert plate 105 to move and separate it from the slot 103, so that the operator can easily disassemble the protective cover 102.

[0043] An electric push rod 102f is provided on the top of the motor 102b. Several insertion rods 102g are provided on the extended end of the electric push rod 102f. When the electric push rod 102f pushes the insertion rods 102g upward, the insertion rods 102g are inserted into the lower end of the rotating shaft 201 and limit the rotating shaft 201. The electric push rod 102f pushes the insertion rods 102g upward and inserts them into the rotating shaft 201, thereby inserting the rotating shaft 201 and reducing the possibility of the rotating shaft 201 rotating. When the electric push rod 102f drives the insertion rods 102g downward, they separate from the rotating shaft 201. At this time, the wind can drive the first fan blade 202 and the rotating shaft 201 to rotate. At the same time, the rotating shaft 201 drives the cleaning plate 204 to rotate and scrape the outer wall of the protective cover 102.

[0044] The specific working principle is as follows: when the motor 102b is running, it drives the winding reel 102d to rotate and wind up the steel cable 102e. At the same time, the guide block 102c guides the steel cable 102e. At this time, the steel cable 102e pulls the insert plate 105 to move and separate it from the slot 103, so that the operator can easily disassemble the protective cover 102.

[0045] Conversely, when the motor 102b drives the winding reel 102d to rotate in the opposite direction, the steel cable 102e is released. At this time, the spring 106 pushes the insert plate 105 to move and insert it into the slot 103, thereby fixing the protective cover 102 to the upper end of the tank 101, and thus protecting the top of the tank 101 through the protective cover 102.

[0046] Example 3, refer to Figures 2-4 In this embodiment, to address the problem that existing protective devices are directly installed on the tank body for protection, but when the protective device is impacted, the impact force is easily transmitted directly to the tank body, thus easily damaging the tank body, based on the same concept as the above embodiment one, this large composite storage tank top protection device further includes: an insert plate 105 including a movable plate 105a and a connecting plate 105b. One end of the movable plate 105a is inserted into the groove 104 and connected to the inner wall of the groove 104 through a spring 106. The connecting plate 105b is fixedly connected to the other end of the movable plate 105a. The end of the steel cable 102e away from the winding reel 102d passes through the guide block 102c and is fixedly connected to the connecting plate 105b. When the motor 102b is running, it drives the winding reel 102d to rotate and wind up the steel cable 102e. At this time, the connecting plate 105b and the movable plate 105a are moved by the steel cable 102e and separated from the slot 103, thereby causing the protective cover 102 to lose its limit, thus making it easier for the operator to disassemble the protective cover 102.

[0047] A compression spring 103a is fixedly connected to the bottom of the inner wall of the slot 103. A top plate 103b is fixedly connected to the upper end of the compression spring 103a. The upper end of the top plate 103b abuts against the bottom surface of the insert plate 105. The top plate 103b is L-shaped. A damper is provided between the top plate 103b and the insert plate 105. The damper reduces the possibility of the protective cover 102 shaking. The compression spring 103a and the top plate 103b cooperate to push the insert plate 105 and the protective cover 102 upward. When the protective cover 102 is impacted, the protective cover 102 drives the insert plate 105 downward. At this time, the compression spring 103a buffers the impact force. Therefore, the protective cover 102 provides better protection for the tank 101.

[0048] The specific working principle is as follows: First, the protective cover 102 is hoisted onto the tank 101. Then, the spring 106 pushes the insert plate 105 to move and insert it into the slot 103, thereby fixing the protective cover 102 to the upper end of the tank 101. The protective cover 102 then protects the top of the tank 101. When the protective cover 102 is impacted, it drives the insert plate 105 to move down. At this time, the compression spring 103a buffers the impact force. Therefore, the protective cover 102 provides better protection for the tank 101.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
