Description

Technical Field

[0001] The utility model relates to the technical field of rain protection for sand tanks, and specifically, to a rain protection device for an underground fracturing combined sand tank. Background Art

[0002] A fracturing sand tank is a large container used for storing, metering, and conveying proppants to a fracturing blender truck, where the proppants are mainly quartz sand or ceramsite. These tanks are usually placed side by side or stacked on the ground to form a sand supply system. A combined sand tank refers to combining multiple independent fracturing sand tanks on the ground to form a larger-capacity, more flexible, and more efficient proppant supply system to meet the demand for a large amount of proppants in large-scale fracturing operations, especially multi-stage fracturing of horizontal wells.

[0003] In the prior art, the openings of fracturing sand tanks are generally open for feeding at any time. When feeding, a crane is used to lift a ton bag, and by puncturing the bottom of the ton bag, quartz sand or ceramsite is released into the feed inlet of the fracturing sand tank. This also causes that once it rains, rainwater can enter the fracturing sand tank, affecting the sand stored in the fracturing sand tank. Content of the Utility Model

[0004] The utility model aims at the above problems and provides a rain protection device for an underground fracturing combined sand tank, which is used to provide a rain protection device that can prevent water from entering the fracturing sand tank in rainy days.

[0005] The utility model is realized through the following technical solutions: A rain protection device for an underground fracturing combined sand tank includes an outer frame, and a "mouth" - shaped frame is fixedly connected inside the outer frame. Rain protection covers are respectively slidably connected to both sides of the top of the "mouth" - shaped frame, and driving members for driving the rain protection covers to slide are fixedly connected to both sides of the outer frame;

[0006] The thickness of one side of the rain protection cover away from the driving member is greater than that of the side close to the driving member.

[0007] Furthermore, several reinforcing beams are provided between the outer frame and the "mouth" - shaped frame.

[0008] Furthermore, telescopic ears and towing hanging rings are provided at the four corners of the outer frame.

[0009] Furthermore, the driving member is an electric push rod.

[0010] Furthermore, the number of electric push rods is 4.

[0011] Furthermore, abutting blocks and air cylinders are respectively fixedly connected to the bottoms of the two rain protection covers on the side away from the driving member, and the nozzles of the air cylinders face the sides of the two rain protection covers away from the driving member.

[0012] The technical solution of the utility model has at least the following beneficial effects:

[0013] In use, the outer frame is installed on the sand tank. During installation, the outer frame is assembled on the inner top wall of the sand tank, so that the "mouth" - shaped frame fits the opening of the sand tank. When it rains, the driving member can be controlled to drive the rain covers to move closer to each other, so that the rain covers close the opening of the sand tank, making it difficult for rainwater to enter the sand tank and ensuring that the sand stored in the sand tank does not come into contact with rainwater.

[0014] The thickness of the side of the rain cover far from the driving member is greater than that of the side close to the driving member, so that the top of the rain cover has a certain slope. Since rainwater is a fluid, when it rains, the rainwater will flow along the top of the rain cover to both sides of the rain cover, so that the rainwater will not accumulate on the rain cover.

[0015] After the rain stops, due to the slope of the rain cover, the rainwater can be drained out, and the accumulation amount is extremely small, which can quickly meet the opening condition for continued operation after opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is a further detailed description through specific embodiments:

[0026] Embodiment 1:

[0027] As shown in the attached Figures 1-5 figure: A rainproof device for an underground fracturing combined sand tank, including an outer frame 1. The size of the outer frame 1 is 2400×2400×200 (a 200-channel formed by folding 5mm steel plates) mm. Inside the outer frame 1, a "mouth" - shaped frame 2 is fixedly welded by a reinforcing beam 5. On both sides of the top of the "mouth" - shaped frame 2, rainproof covers 3 are respectively slidably connected. The size of the rainproof cover 3 is 1400×1000×100 (a 100-channel formed by folding 5mm steel plates) mm. On both sides of the outer frame 1, driving members 4 for sliding the rainproof cover 3 are bolt - fixed; the thickness of one side of the rainproof cover 3 away from the driving member 4 is greater than the thickness of the side close to the driving member 4. Specifically, the thickness of the side of the rainproof cover 3 away from the driving member 4 is 14mm, and the thickness of the side close to the driving member 4 is 5mm.

[0028] At the four corners of the outer frame 1, telescopic ears 6 and traction hanging rings 7 are fixedly welded.

[0029] The driving member 4 is an electric push rod. The number of electric push rods is 4, and all 4 electric push rods are equipped with synchronizers, and the synchronizers are used to control the synchronous start and stop of the electric push rods.

[0030] In use, the outer frame 1 is installed onto the sand jar. During installation, the outer frame 1 is fitted onto the inner top wall of the sand jar, ensuring the "U"-shaped frame 2 fits snugly against the opening of the sand jar. During installation, the outer frame 1 can be lifted using the traction ring 7, bringing it to the desired installation position for easy operation. The telescopic lug 6 serves for leveling. When the outer frame 1 is suspended in the air by the traction ring 7, it may be tilted. The telescopic lug 6 can be extended or shortened to fine-tune the center of gravity of the outer frame 1, maintaining its balance and facilitating operation.

[0031] When it rains, the drive unit 4 can control the rain cover 3 to move closer together, sealing the opening of the sand container and preventing rainwater from entering, thus ensuring that the sand stored inside does not come into contact with rainwater. The electric push rod can drive the rain cover 3 to move closer together, and the synchronizer on the electric push rod can make the electric push rod start and stop synchronously, ensuring consistency of operation and reducing the probability of mechanical damage due to asynchrony.

[0032] The side of the rain cover 3 furthest from the drive component 4 is thicker than the side closest to the drive component 4, giving the top of the rain cover 3 a certain slope. Since rainwater is a fluid, it flows along the top of the rain cover 3 to both sides during rain, preventing rainwater from accumulating on the rain cover 3. After the rain stops, the slope of the rain cover 3 allows rainwater to be discharged, resulting in minimal accumulation and enabling faster opening of the cover for continued operation.

[0033] Example 2:

[0034] The difference from the above embodiment is that: the bottom of the two rain covers 3 away from the driving member 4 is respectively bolted with a stop block 8 and an air cylinder 9, the air nozzle 901 of the air cylinder 9 is located at the top of the air cylinder 9, and the air nozzle 901 of the air cylinder 9 faces the side of the two rain covers 3 away from the driving member 4.

[0035] The rain cover 3 closes when it rains, thus preventing rainwater from entering. The effectiveness of the seal of the rain cover 3 determines whether it can completely prevent rainwater from entering. Since the sand tank normally stores sand through an opening, the sand entering the sand tank through the opening may adhere to the contact surfaces of the two rain covers 3. When the rain covers 3 are closed, the adhered sand may cause damage through abrasion and reduce the sealing performance of the rain covers 3.

[0036] In this embodiment, when the rain cover 3 is closed, the abutment 8 contacts the air cylinder 9 before the rain cover 3 closes. As the rain cover 3 approaches each other, it squeezes the air cylinder 9, causing the air cylinder 9 to expel gas and release it from the air nozzle 901. The released gas impacts the contact surface of the rain cover 3, blowing away the sand adhering to the contact surface, thereby reducing the abrasive effect of the sand and extending the service life of the rain cover 3.

[0037] Furthermore, the contact between the block 8 and the air cylinder 9 can form a new closed surface, which can intercept rainwater seeping out of the closed seam of the rain cover 3 for a second time, thereby reducing the probability of rainwater entering the sand tank.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
