Description

Technical Field

[0001] This utility model relates to the field of salt production technology, specifically to a negative pressure windproof device for salt granaries. Background Technology

[0002] Salt granaries are places in salt fields used to store salt produced during the drying process. To prevent rainwater from washing away the salt, they need to be completely covered with rainproof plastic sheeting. Windproof netting and windproof counterweights should then be added on top of the rainproof plastic sheeting.

[0003] Currently, to prevent the rainproof plastic sheet covering the salt granary from being blown away by strong winds, it is necessary to add windproof nets and windproof counterweights on the rainproof plastic sheet. However, in daily work, the workload of manual operation is relatively large, the efficiency is low, and the material consumption is large. Therefore, we propose a negative pressure windproof device for salt granaries. Utility Model Content

[0004] The purpose of this utility model is to provide a negative pressure windproof device for salt sheds, which enables the rainproof plastic sheet to be tightly covered on the salt shed under negative pressure, preventing it from being blown away by strong winds. This eliminates the need for windproof nets and windproof counterweights, greatly reducing the workload of workers, lowering labor intensity, and improving work efficiency. It solves the problem that currently, to prevent the rainproof plastic sheet covering the salt shed from being blown away by strong winds, it is necessary to add windproof nets and windproof counterweights on the rainproof plastic sheet. However, in daily work, the workload of manual operation is relatively large, the efficiency is low, and a lot of materials are consumed.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a negative pressure windproof device for a salt pan, comprising a rainproof plastic sheet and an exhaust pipe, wherein the upper surface of the rainproof plastic sheet is provided with a through-hole, and a raised ring is provided on the upper surface of the rainproof plastic sheet above the through-hole, and the exhaust pipe passes through the raised ring and the through-hole.

[0006] Preferably, the outer surface of the raised ring is provided with a fixing strap, which makes the raised ring tightly attached to the outer surface of the suction pipe, thereby achieving a sealing effect.

[0007] Preferably, the extraction pipe is equipped with a tripod bracket inside. The tripod bracket is inserted into the salt silo to fix the extraction pipe in place, so as to prevent the extraction pipe from being inserted into the salt silo, thereby facilitating the extraction pipe to remove the air between the rainproof plastic sheet and the salt silo.

[0008] Preferably, a raised baffle is provided on the upper surface of the rainproof plastic sheet near the edge. When rainwater falls on the rainproof plastic sheet, it blocks the rainwater, allowing some rainwater to accumulate at the edge of the rainproof plastic sheet. The weight of the rainwater makes the edge of the rainproof plastic sheet adhere tightly to the ground. At the same time, the raised baffle can also prevent the counterweight on the edge of the rainproof plastic sheet from slipping off.

[0009] Preferably, a flexible sealing strip is fixedly installed on the lower surface of the rainproof plastic fabric near the edge. The flexible sealing strip seals the edge of the lower surface of the rainproof plastic fabric with the ground, preventing rainwater from flowing into the salt pan and also preventing a large amount of air from entering between the salt pan and the rainproof plastic fabric.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a rainproof plastic sheet, a through-hole, a raised ring, and an air extraction pipe, achieves the effect of allowing the rainproof plastic sheet to tightly cover the salt silo under negative pressure, preventing it from being blown away by strong winds. This eliminates the need for windproof nets and windproof counterweights, greatly reducing the workload of workers, lowering labor intensity, and improving work efficiency. By covering the salt silo with the rainproof plastic sheet and using weights to press down the edges of the rainproof plastic sheet, and removing the air between the rainproof plastic sheet and the salt silo through the air extraction pipe, the rainproof plastic sheet tightly covers the salt silo under negative pressure and will not be blown away by strong winds.

[0012] 2. By setting a tripod fixing bracket, this utility model achieves the effect of better removing the air between the rainproof plastic sheet and the salt silo by the suction pipe. The tripod fixing bracket is inserted into the salt silo to fix the suction pipe, so as to prevent the suction pipe from being inserted into the salt silo, thereby facilitating the suction pipe to remove the air between the rainproof plastic sheet and the salt silo.

[0013] 3. By setting up raised baffles, this utility model can block rainwater when it falls on the rainproof plastic sheet, so that some rainwater accumulates at the edge of the rainproof plastic sheet. The weight of the rainwater makes the edge of the rainproof plastic sheet adhere tightly to the ground. At the same time, the raised baffles can also prevent the counterweight on the edge of the rainproof plastic sheet from slipping off.

[0014] 4. This utility model uses a flexible sealing strip to seal the edge of the lower surface of the rainproof plastic sheet and the ground, preventing rainwater from flowing into the salt pan and also preventing a large amount of air from entering between the salt pan and the rainproof plastic sheet.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model proposes a negative pressure windproof device for salt silos, including a rainproof plastic sheet 1 and an air extraction pipe 2. The rainproof plastic sheet 1 covers the salt silo to prevent rainwater from washing away the salt. A through-hole 8 is provided on the upper surface of the rainproof plastic sheet 1, and a raised ring 5 is provided on the upper surface of the rainproof plastic sheet 1 above the through-hole 8. The raised ring 5 and the rainproof plastic sheet 1 are integrally formed, and the air extraction pipe 2 passes through the raised ring 5 and the through-hole 8, and the air extraction pipe 2 draws air out from between the salt silo and the rainproof plastic sheet 1. When the rainproof plastic sheet 1 is in place, it tightly covers the salt silo under negative pressure. The outer surface of the raised ring 5 is provided with a fixing strap 4, which makes the raised ring 5 tightly attached to the outer surface of the suction pipe 2, thus achieving a sealing effect. The suction pipe 2 is provided with a tripod fixing bracket 7. The tripod fixing bracket 7 is inserted into the salt silo, which fixes the suction pipe 2 to prevent it from being inserted into the salt silo, thereby facilitating the suction pipe 2 to remove the air between the rainproof plastic sheet 1 and the salt silo.

[0023] In use, the rainproof plastic sheet 1 is placed over the salt silo, and the edges of the rainproof plastic sheet 1 are pressed down with a weight. The tripod bracket 7 is inserted into the salt silo to fix the air extraction pipe 2. The air is then removed from between the rainproof plastic sheet 1 and the salt silo through the air extraction pipe 2. Under the action of negative pressure, the rainproof plastic sheet 1 is tightly covered over the salt silo and will not be blown away by strong winds. This eliminates the need for windproof nets and windproof counterweights, greatly reduces the workload of workers, reduces labor intensity, and improves work efficiency.

[0024] Example 2

[0025] like Figure 1 and Figure 3 As shown, the present invention proposes a negative pressure windproof device for a salt pan. Compared with the first embodiment, this embodiment also includes a raised baffle 3 on the upper surface of the rainproof plastic cloth 1 near the edge. The raised baffle 3 and the rainproof plastic cloth 1 are integrally formed. A flexible sealing strip 6 is fixedly installed on the lower surface of the rainproof plastic cloth 1 near the edge.

[0026] In this embodiment, when rainwater falls onto the rainproof plastic sheet 1, the raised baffle 3 acts as a barrier, causing some rainwater to accumulate at the edge of the rainproof plastic sheet 1. The weight of the rainwater causes the flexible sealing strip 6 on the lower surface edge of the rainproof plastic sheet 1 to adhere tightly to the ground, preventing rainwater from flowing into the salt silo and also preventing a large amount of air from entering between the salt silo and the rainproof plastic sheet 1. At the same time, the raised baffle 3 can also prevent the counterweight on the edge of the rainproof plastic sheet 1 from slipping off.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
