Description

Technical Field

[0001] The utility model relates to the technical field of meteorological monitoring, and in particular to a sandstorm concentration monitoring device. Background Art

[0002] Dust storm is the general term for sandstorm and dust storm, which is a sign of desertification. It refers to the weather phenomenon that strong winds roll up a large amount of sand and dust from the ground, making the horizontal visibility less than 1 km. This phenomenon is characterized by suddenness and short duration. Although the probability is small, it is very harmful. Among them, sandstorm refers to a sand-carrying storm formed by strong winds blowing a large amount of sand into the near-ground layer, while dust storm is a storm formed by strong winds rolling a large amount of dust and other fine particles into the high altitude. Sandstorm is a weather phenomenon in wind erosion desertification, and its formation is jointly affected by natural factors and human activities. Natural factors include strong winds, reduced precipitation and sand sources. Human activity factors refer to the destruction of vegetation by humans in the process of economic development, which leads to an increase in the frequency of sandstorm outbreaks. Sandstorm weather mainly occurs in winter and spring. This is because there is little precipitation in semi-arid and arid areas in winter and spring, the surface is extremely dry and loose, and the ability to resist wind erosion is very weak. When there is a strong wind, a large amount of sand and dust will be rolled into the air, forming sandstorm weather.

[0003] Dust storm is a common natural disaster that has a serious impact on human society and the natural environment. In order to effectively deal with sandstorms, the prior art usually uses a sandstorm concentration monitoring device to monitor sandstorms, so as to timely and accurately grasp the concentration information of sandstorms, and timely grasp the coverage area and movement path of sandstorms, and issue timely warnings to human activities to reduce losses. However, in the actual application of the existing monitoring device, since there is no protective structure, when a sandstorm passes, large solid objects such as branches and soil blocks carried by strong winds will hit the sampling detection head on the device at a relatively fast speed, causing a large impact on it, resulting in wear on the surface of the sampling detection head, and in severe cases, damage, affecting the monitoring of sandstorms. Therefore, there is an urgent need for a sandstorm concentration monitoring device with a protective function that can protect the sampling detection head from damage to solve the above problems. Utility Model Content

[0004] In view of the existing deficiencies, the utility model provides a sandstorm concentration monitoring device, which solves the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A dust storm concentration monitoring device comprises a column, an electric control box is installed on the upper side of the column, a base plate is fixedly arranged on the top of the electric control box in the horizontal direction, a wind vane is installed on the left end of the base plate, a wind speed sensor is arranged on the right end of the base plate, a sampling detection head is fixedly installed on the upper side of the base plate, a protective mechanism is arranged on the outside of the sampling detection head, the protective mechanism comprises a shielding cover, a protective mesh cover, a locking assembly and a positioning pressure plate, the protective mesh cover is arranged on the outside of the sampling detection head, a shielding cover is arranged on the top of the protective mesh cover, arc-shaped positioning pressure plates are fixedly arranged on the left and right sides of the annular surface of the protective mesh cover near the bottom, a locking assembly is arranged on the base plate outside the positioning pressure plate, and the positioning pressure plate is fixed to the base plate by the locking assembly.

[0007] Furthermore, the diameter of the shielding cover is larger than the diameter of the protective mesh cover, and slots are provided on the left and right sides of the upper end surface of the shielding cover near the edge. Ear plates are fixed on the left and right sides of the upper end of the protective mesh cover, and the shielding cover is mounted on the ear plates through the slots. Pin rods are provided inside the two groups of ear plates.

[0008] Furthermore, an inspection slot is provided on the front side of the protective mesh cover ring, and a movable mesh cover matching the inspection slot is provided at the inspection slot.

[0009] Furthermore, a plurality of groups of buckles are fixedly provided at the upper and lower edges of the inspection slot, and the movable net cover is detachably connected to the slot via the buckles.

[0010] Furthermore, the locking assembly includes a handle, a fixed box, a supporting spring, a connecting rod and a clamping block. The fixed box is fixed on the bottom plate outside the positioning pressure plate. A connecting rod is horizontally penetrated inside the fixed box. A supporting spring is sleeved on the connecting rod. A clamping block with an inclined upper end surface is fixed on the right end of the connecting rod. The left end of the connecting rod extends from the fixed box and a handle is fixed on it.

[0011] Furthermore, two groups of limit baffles are symmetrically fixed on the upper surface of the positioning pressure plate, and the two groups of limit baffles are respectively located at the front and rear sides of the clamping block.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model can effectively protect the sampling detection head from the impact of larger objects caught in the sandstorm by the protective mechanism provided, thereby improving the protective effect of the sampling detection head, thereby extending its service life and ensuring the accuracy and continuity of sandstorm monitoring.

[0014] 2. The utility model can protect the sampling and monitoring head inside the protective cover from the upper side through the shielding cover, provide more comprehensive protection for the sampling and detection head, and at the same time play the role of shielding against wind and rain, which can reduce the aging of the sampling and monitoring head. The shielding cover can be limited and fixed by the ear plate and the pin rod, ensuring the stable connection between the shielding cover and the protective mesh cover, and improving the stability of the shielding cover.

[0015] 3. The inspection slot allows the staff to access the sampling detection head more conveniently, which is convenient for regular inspection and maintenance of the sampling detection head. At the same time, the inspection slot can be closed by the movable net cover, so that the protective net cover forms a whole, ensuring comprehensive protection of the sampling monitoring head.

[0016] 4. The locking assembly is used to tighten and fix the positioning pressure plate, which can ensure that the protective mesh cover is stably fixed on the bottom plate. When installing the protective mesh cover, place the protective mesh cover on the outside of the sampling monitoring head, press the protective mesh cover downward, and make the positioning pressure plate contact the card block. When the positioning pressure plate contacts the card block, due to the inclined design of the upper end face of the card block, the positioning pressure plate will gradually slide downward under pressure, while pushing the card block to move outward. When the positioning pressure plate is inserted into the lower side of the card block and contacts the bottom plate, the elastic force of the supporting spring drives the card block to move in the opposite direction and reset, ensuring that the card block fits tightly on the positioning pressure plate, thereby forming a stable locking state. When unlocking is required, the operator only needs to pull the handle outward to make the card block gradually slide out of the locked position, and then the protective mesh cover can be easily removed.

[0017] 5. Two sets of limit baffles are symmetrically fixed on the upper surface of the positioning plate, and the two sets of limit baffles are respectively located on the front and rear sides of the block. The limit baffles can limit the block from the side, effectively preventing the protective net from rotating, and further improving the stability of the protective net.

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 5 As shown, a dust storm concentration monitoring device comprises a column 1, an electric control box 2 is installed on the upper side of the column 1, a bottom plate 7 is fixedly arranged on the top of the electric control box 2, a wind vane 3 is mounted on the left end of the bottom plate 7, a wind speed sensor 4 is arranged on the right end of the bottom plate 7, a sampling detection head is fixedly installed on the upper side of the bottom plate 7, and the electric control box 2, the wind speed sensor 4 and the sampling detection head all adopt corresponding components of the dust storm concentration monitoring device in the prior art. A protective mechanism 5 is arranged on the outside of the sampling and detection head, and the protective mechanism 5 includes a shielding cover 51, a protective mesh cover 53, a locking assembly 55 and a positioning pressure plate 56. The protective mesh cover 53 is arranged on the outside of the sampling and detection head, and a shielding cover 51 is arranged on the top of the protective mesh cover 53. The left and right sides of the ring surface of the protective mesh cover 53 near the bottom are fixed with arc-shaped positioning pressure plates 56, and a locking assembly 55 is arranged on the bottom plate 7 outside the positioning pressure plate 56. The positioning pressure plate 56 is fixed to the bottom plate 7 through the locking assembly 55. This design solves the problem that in the actual application of the existing monitoring device, due to the lack of a protective structure, when a sandstorm passes, larger solid objects carried by the strong wind, such as branches and soil blocks, will hit the sampling and detection head on the device at a faster speed, causing a greater impact on it, resulting in wear on the surface of the sampling and detection head, and in severe cases, damage, thereby affecting the monitoring of the sandstorm.

[0027] The diameter of the shielding cover 51 is larger than the diameter of the protective mesh cover 53. Slots 511 are provided on both sides of the upper end surface of the shielding cover 51 near the edge. Ear plates 531 are fixed on both sides of the upper end of the protective mesh cover 53. The shielding cover 51 is sleeved on the ear plates 531 through the slots 511. Pins 532 are provided inside the two groups of ear plates 531. The shielding cover 51 can protect the sampling and monitoring head 6 inside the protective cover from the upper side, providing more comprehensive protection for the sampling and detection head, while playing a role in shielding from wind and rain, and can reduce the aging of the sampling and monitoring head 6. The ear plates 531 and the pins 532 can limit and fix the shielding cover 51, ensure the stable connection between the shielding cover 51 and the protective mesh cover 53, and improve the stability of the shielding cover 51.

[0028] An inspection slot 54 is provided on the front side of the protective mesh cover 53, and a matching movable mesh cover 52 is provided at the inspection slot 54. The inspection slot 54 allows the staff to more conveniently access the sampling and detection head, which is convenient for regular inspection and maintenance of the sampling and detection head. At the same time, the inspection slot 54 can be closed by the movable mesh cover 52, so that the protective mesh cover 53 forms a whole, ensuring comprehensive protection of the sampling and monitoring head 6.

[0029] Multiple sets of buckles 541 are fixed at the upper and lower edges of the inspection slot 54, and the movable net cover 52 is detachably connected to the slot through the buckles 541. The multiple sets of buckles 541 are convenient for clamping and fixing the movable net cover 52, ensuring the connection stability between the movable net cover 52 and the protective net cover 53.

[0030] The locking assembly 55 includes a handle 551, a fixing box 552, a support spring 553, a connecting rod 554 and a block 555. The fixing box 552 is fixed on the bottom plate 7 outside the positioning plate 56. A connecting rod 554 is arranged horizontally inside the fixing box 552. The connecting rod 554 is sleeved with a support spring 553. The right end of the connecting rod 554 is fixed with a block 555 with an inclined upper end surface. The left end of the connecting rod 554 extends out of the fixing box 552 and is fixed with a handle 551. The locking assembly 55 is used to press and fix the positioning plate 56, which can ensure that the protective net cover 53 is stably fixed on the bottom plate 7. When installing the protective net cover 53, the protective net cover 53 is placed outside the sampling monitoring head 6, and the protective net cover 53 is pressed downward to make the positioning plate 56 contact the block 555. When the positioning plate 56 contacts the block 555, due to the inclined design of the upper end surface of the block 555, the positioning plate 56 will gradually slide downward under pressure, while pushing the block 555 to move outward. When the positioning plate 56 is inserted into the lower side of the block 555 and contacts the bottom plate 7, the elastic force of the support spring 553 drives the block 555 to move in the opposite direction and reset, ensuring that the block 555 fits tightly on the positioning plate 56, thereby forming a stable locking state. When unlocking is required, the operator only needs to pull the handle 551 outward to make the block 555 gradually slide out of the locking position, and then the protective net cover 53 can be easily removed.

[0031] Two groups of limit baffles 561 are symmetrically fixed on the upper surface of the positioning plate 56, and the two groups of limit baffles 561 are respectively located at the front and rear sides of the block 555. The limit baffles 561 can limit the block 555 from the side, effectively preventing the protective net cover 53 from rotating, and further improving the stability of the protective net cover 53.

[0032] The working principle of the dust storm concentration monitoring device is as follows: the protective mechanism 5 can effectively protect the sampling detection head from being hit by larger objects in the dust storm, thereby improving the protective effect of the sampling detection head, thereby extending its service life and ensuring the accuracy and continuity of the dust storm monitoring. During installation, the protective mesh cover 53 is first sleeved on the outside of the sampling monitoring head 6, and then the protective mesh cover 53 is pressed downward to make the positioning plate 56 contact the block 555. When the positioning plate 56 contacts the block 555, due to the inclined design of the upper end face of the block 555, the positioning plate 56 will gradually slide downward under pressure, while pushing the block 555 to move outward. When the positioning plate 56 is inserted into the lower side of the block 555 and contacts the bottom plate 7, the elastic force of the support spring 553 drives the block 555 to move in the opposite direction and reset, ensuring that the block 555 is tightly fitted on the positioning plate 56, thereby forming a stable locking state. When unlocking is required, the operator only needs to pull the handle 551 outward to make the block 555 gradually slide out of the locked position, and then the protective mesh cover 53 can be easily removed. The inspection slot 54 provided enables the staff to more conveniently access the sampling and detection head, which is convenient for regular inspection and maintenance of the sampling and detection head. At the same time, the inspection slot 54 can be closed by the movable mesh cover 52 provided, so that the protective mesh cover 53 forms a whole, ensuring comprehensive protection of the sampling and monitoring head 6. The shielding cover 51 is sleeved on the ear plate 531 through the slot 511 and is fixed by the pin 532. The shielding cover 51 can protect the sampling and monitoring head 6 inside the protective cover from the upper side, provide more comprehensive protection for the sampling and detection head, and at the same time play a role in sheltering from wind and rain, which can reduce the aging of the sampling and monitoring head 6.

[0033] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
